Background: Red eye is a frequently encountered condition by primary care doctors both in the in-patient and ambulatory settings. While most cases can be easily managed, it is important that the astute physician recognizes cases which require immediate referral to a specialist to prevent vision loss.

Case Report: We report a 78 year old female who presented with a red eye since 3 days. She denied any vision changes. Past medical history included Glaucoma, HTN, DM, CVA, and hypothyroidism. She had undergone bilateral extracapsular cataract extraction, glaucoma filtration procedure in the left eye and pan-retinal photocoagulation for proliferative diabetes mellitus. On evaluation in the affected eye she was noted to have 20/60 vision and hypotony, with an IOP (intra-ocular pressure) of 5 mm Hg. The slit lamp exam revealed a turbid, thin avascular bleb with surrounding injection of the conjunctiva.  The corneal exam was unremarkable. Funduscopic exam showed choroidal folds with serous retinal detachment. A subsequent vitreal tap was negative for any infection. Her vision eventually worsened to 20/400. Upon treatment with oral and intra-ocular antibiotics, her bleb showed increasing translucency with a decrease in inflammation. Her hypotony resolved and subsequently her choroidal folds resolved as well. At last check her vision was 20/80 and intraocular pressure was 11 mm Hg. 

Discussion:  In a patient with known glaucoma filtration surgery, primary care physicians should entertain the possibility of a bleb infection (blebitis) as a cause of red eye. The filtering bleb is a rather thin walled structure. In some cases the wall is extremely thin and intermittently even leaks fluid through it. This is not unusual in a person who has had a very successful glaucoma operation in the past. This requires immediate attention as, if blebitis occurs, it quickly can lead to endophthalmitis. Endophthalmitis commonly can cause severe loss of vision. Blebitis in our case, resulted in overfiltration, leading to hypotony and resulting in choroidal folds and retinal detachment.

Sinai-Grace Hospital, Detroit Medical Center/Wayne State University, Detroit, Michigan.

 

Introduction:  Malignant mesothelioma (MM) is a rare malignant tumor which arises from the mesothelial surfaces of pleura and peritoneum. The tumor is significant in view of its recognized association with occupational exposure to asbestos. Prolonged asbestos exposure is considered more significant rather than heavy exposure.

 

Case Report:  A 54 year old retired assembly line worker with a history of COPD and 20 pack year smoking history presented with progressively worsening dyspnea of 2 weeks.  He was tachypneic, tachycardic and hypoxic using accessory muscles, had decreased breath sounds on right lower lung field and diffuse crackles bilaterally. Patient had to be intubated in the ER for worsening dyspnea and hypoxia. Chest X-ray showed right sided pleural effusion. CT guided thoracentesis revealed bloody pleural fluid with lymphocytosis and mesothelial cells. Pleural biopsy showed areas of poorly differentiated malignant neoplasm with focal areas of necrosis and mitosis, epitheloid cells with  pleomorphic nuclei intermixed with neoplastic spindle cells with elongated nuclei. This kind of mixed pattern is characteristic for mesothelioma. Staining was positive for cytokeratin and calretinin, which favored a diagnosis of mesothelioma.  The patient is currently oxygen dependent and followed up as out patient, awaiting  chemotherapy with cisplatin and alimta.

 

Discussion:  We report a unique case of localized malignant mesothelioma presenting with dyspnea and unilateral pleural effusion in a patient with a risk of occupational exposure to asbestos. Lifetime risk of developing mesothelioma is 8-13 % in workers exposed to asbestos. The incidence of mesothelioma is expected to increase till 2020 and then decrease due to environmental legislation in place since 1990. There are almost 2500 new cases every year. Average survival time is one year. There are new emerging therapies that improve survival and provide palliation.   It is therefore important that this serious condition be recognized as a differential diagnosis in patients presenting like ours.

Bhavin Dalal, MD, (Associate); Ishani Dalal, MD; Pranav Dalal, MD; Umang Shah, MD; Suniel Dalal, MD; Kamal Nasser, MD

Introduction: Despite the rise in occurrence, echinococcosis remains a very rare disease (<1 case per 1 million inhabitants) in the continental United States. 60% of the hydatid cysts are found in liver, 30% in lungs, 2.5% in kidney, 2.5% in heart and pericardium and 5% in other areas. We are reporting a case report of multiple hydatid cysts in heart.

Case report: A 30 year old male came to the out patient clinic with complaints of intermittent chest pain & palpitations. Physical examination was normal except PMI was displaced laterally. EKG was showing RVH with RBBB. 2D echo showed multiple well defined cystic lesions with presence of daughter cysts, the appearance compatible with Hydatid Cyst. Patient underwent for open heart surgery and all the cysts were removed. Patient was also prescribed Albendazole (400 mg twice a day) for period of 12 weeks. Postoperative 2D Echo didn’t reveal any cyst.

Discussion: Cardiac involvement of hydatid cyst is rare though, solitary hydatid cyst of heart is well documented. In our patient there were multiple cysts in heart with predominance in RV and IVS. In spite of that he was minimally symptomatic. Diagnosis of hydatid cyst in heart can be easily made by 2D echo. CT scan or MRI may help for lesions with mixed echogenic pattern on echocardiography. Casoni’s test, complement fixation, indirect haemagglutination, latex agglutination and indirect fluorescent antibody tests are used to make diagnosis. Cysts excision is the mainstay of treatment. If untreated, hydatid cyst of heart can cause arrhythmia, syncope, rupture of cyst in heart. Albendazole or Mebendazole is given to sterilize the cyst and to prevent recurrence if spillage occurred during surgery. Public education is essential to prevent echinococcosis.

 

 

 

 

 


Morgagni’s hernia as a cause of Hemodynamic instability – A rare entity!

Dalal B MD (Associate), Sinai-Grace Hospital / Detroit Medical Center, Wayne State University, Detroit, Michigan

Dhar S, MD, Dalal S MD, Desai N MD Department of Internal Medicine,Temple University Hospital, Philadelphia, PA

 

Introduction: The liver, bowel, or mesenteric fat may herniate directly through small congenital defects in the anterior diaphragm (i.e., Morgagni's foramina). We are reporting a case in which Morgagni’s hernia was responsible for hemodynamic instability and surgical emergency.

Case Report: A 63 year old man was transferred to the hospital with two episodes of hematemesis at boarding home. EGD revealed erosive esophagitis and a healing duodenal ulcer without an active source of bleeding.  On the evening of day two, patient was restless and 2 mg of lorazepam was given intravenously. Subsequently he became lethargic and he was intubated for hypercapnic failure. On third day patient dropped his blood pressure tachycardia. He was aggressively hydrated without any significant response. Patient was started on dopamine drip. A thoracic radiograph revealed increased cardiac silhouette and some gaseous shadows in mediastinum. Subsequently a stat chest CT scan was performed which revealed a huge Morgagni’s hernia compressing the heart anteriorly and causing atelectasis of left lower lobe of lung. Patient was taken to operating room, where laparoscopic reduction of Morgagni’s hernia was performed with closure of defect.

Discussion: Morgagni’s hernia accounts for 2-4% of all diaphragmatic herniae. The majorities of hernias occurs on the right side and are asymptomatic. In our patient Morgagni’s hernia caused compression of heart from anteriorly and mimicked like a cardiac temponade. Surgical closure is required in all symptomatic patients.

 

 

 

 


Determinants of Central Apneas in Patients with Sleep-Disordered Breathing

Dalal Bhavin, MD, Ghabhsa Ahmed, MD, Badr Safwan, MD, Rowley James, MD

Detroit Medical Center, Wayne State University

Introduction: Research has shown that men are more susceptible to the development of central apneas compared to women under research conditions, suggesting that gender differences in the control of ventilation may explain the increased prevalence of sleep-disordered breathing (SDB) in men.  It is unclear if this physiologic finding translates into a clinical finding of increased central apneas in men presenting for evaluation of SDB. Hypothesis: men are more likely than women to have an increased central apnea index on polysomnography.

Methods: Database review of 773 patients diagnosed with sleep apnea (AHI &#8805;5) between 8/2001 and 7/2004.  Records were reviewed for gender, age, body mass index (BMI), neck circumference (NC), co-morbidities including hypertension, heart disease, diabetes mellitus and tobacco use, apnea-hypopnea index (AHI), central apnea index (CAI), and obstructive apnea index (OAI). Patients were divided into two groups: Group 1, CAI&#8805;5/hr (n=91), Group 2, CAI<5 (n=682). Demographic and comorbid parameters and indices of SDB were compared between the groups. Multivariate logistic regression was performed to determine the independent predictors of the presence of a CAI &#8805;5/hr.

Results: Group 1 patients were more likely to be male (60.4% v. 37.0%). NC was larger in Group 1 patients (44.1±5.1 cm v. 41.9±5.1 cm, Group 2, p<0.001) but there was no difference in either age (48.0±14.9 yrs v. 50.1±13.0 yrs) or BMI (41.3±10.2 kg/m2 v. 41.1±11.5 kg/m2).  Both AHI (111.3±71.9 v. 51.4±49.8, p<0.001) and OAI (68.1±61.3 v. 36.7±45.9, p<0.001) were increased in Group 1 compared to Group 2. The prevalence of comorbidities did not differ between the two groups. After multiple logistic regression, gender (OR 2.00, p=0.012), AHI (OR 1.04, p<0.001) and OAI (OR 0.97, p<0.001) but not NC were found to be independent predictors of a CAI&#8805;5/hr.

Conclusions: Men are twice as likely to demonstrate central apneas on polysomnography than women, consistent with the research finding of an increased susceptibility to the development of central apnea. Central apneas are also more likely in patients with increased overall AHI, suggesting that all types of SDB are more common in patients with severe disease.

 

 

 

 


Solitary Plasmacytoma presenting as Spinal compressions syndrome

Jeevan C. Gowda M.D. Associate, Lourin Chahin M.D. Associate, Dr. Tanu Sahay M.D. Member

Case Presentation

We present the case of an 85-year-old African American Male with a previous history of hypertension, congestive heart failure, and previous tumor of the pituitary gland, which was surgical resected.  He presents with a history of progressive weakness over the past three days prior to admission.   Patient was using his wife’s old walker to ambulate when he lost all function of his lower extremities and called EMS.  He also complains of urinary and bladder disturbances.  Patient denied any back pain, trauma or history of falls.   His neurological exam showed absence of all sensation up to the T8 level. Patient also had reduced power 0/5 in both lower extremities. As well as loss of DTR and loss of sphincter tone.  A Stat MRI of the patients back showed a mass of the spinal cord at the level of L5-L6.  Neurosurgery was consulted for decompression and the patient was started on Dexamethasone.  Histological examination of the tumor showed sheets of plasma cells, consistent with a plasma cell tumor with Kappa cell restriction.

Discussion

Though normally presenting with back pain, spinal cord compression is one of the presentations of plasmacytoma.  Treatment is surgical decompression followed by Radiotherapy.  The patient should be monitored with serum and urine immunofixation every 4-6 months for the 1st year and then annually, for Multiple Myeloma.  As well as Annual MRI’s to rule out local recurrence.

 

 

 

 

 


ACQUIRED ANGIOEDEMA AS A PARANEOPLASTIC PHENOMENON SECONDARY TO HODGKIN'S DISEASE.

Introduction:  Angioedema is characterized by extravasation of fluid into interstitial tissues. It can be mast cell mediated or complement mediated. The complement mediated can be hereditary or acquired.  Acquired angioedema subtype is usually seen in the second or third decade of life and is usually due to an underlying disease. We report a case of acquired angioedema in a patient with Hodgkin’s disease.

Case Report: A 35-year-old African American female came with multiple episodes of angioedema and weight loss of 50 lbs for last four months. No previous documented cases of angioedema in her family were reported. Physical examination was normal except for angioedema of the upper lip. There was no evidence of lymphadenopathy. Chest x-ray and CT scan showed anterior mediastinal mass. Patient underwent resection of the mass. Pathology showed classic Hodgkin’s lymphoma, syncytial variant of nodular sclerosis type. Patient’s CT scan of abdomen, pelvis and bone marrow biopsy were negative. PET scan showed increased uptake in mediastinum. She was diagnosed to have stage 2B Hodgkin’s disease. Serum levels of C3, C4, and functional C1-esterase inhibitor were normal. Pt is being treated with ABVD chemotherapy.

Discussion: Acquired C1-inhibitor deficiency is well recognized in B-cell lymphoproliferative disorders with a prevalence of approximately 0.5%. The typical association of acquired angioedema is with non-Hodgkin’s lymphoma. Upon review of English literature, there was one reported case of acquired angioedema secondary to Hodgkin’s disease. 

Conclusion: Patients with angioedema are often referred to an allergist to rule out an allergic cause. In most cases no allergic cause is identified and the cases are labeled as “idiopathic.” An adult onset angioedema without family history should raise the suspicion of other underlying diseases. The clinician should be aware of the possibility of Hodgkin’s disease as a cause of this paraneoplastic phenomenon.

 

 

 

 

 


Hemodynamic and Clinical Changes in Patients Following Alcohol Septal Ablation for Hypertrophic Obstructive Cardiomyopathy

Irfan Hameed, MD, Associate, Amr Abbas, MD, Stacy Brewington, MD, Judy Boura, MS, William O’Neil, MD, Sinai Grace Hospital and William Beaumont Hospital, Michigan

 

Background:

Dynamic left ventricular outflow tract obstruction is an important determinant of patient’s symptoms and prognosis. Relief of outflow obstruction leads to positive clinical and hemodynamic effects. Alcohol Septal Ablation (ASA) is a reliable alternative to surgical myomectomy in symptomatic patients with Hypertrophic Cardiomyopathy (HCM) who fail medical therapy. We sought to determine the clinical and hemodynamic benefits following the procedure.

Methods:

A retrospective analysis of 40 patients who underwent ASA for HCM from 1999 to 2004 was conducted. Baseline clinical and echocardiographic findings were reviewed and compared at follow up. The changes from baseline to follow-up were compared using a chi-square or fisher's exact test. The differences were tested using a paired t-test. A p<0.05 was considered significant.

Results:

The mean age was 52 with 63% male. Median clinical follow up was 80 days and echocardiographic follow up was 46 days.

Clinically, a sustained improvement was noted in NYHA class, chest pain, palpitation, syncope, and use of medications. The majority of patients were NYHA class 3-4 at baseline (86%) and improved to class 1 (26%) at follow up, seventy percent of patients had no symptoms. Similarly, by echo an improvement in septal thickness (from 2.2 ± 0.6 to 1.6 ± 0.4 cm, P<0.0019), mitral regurgitation (from 96% to 58%, P< 0.039), and outflow gradient (from 74.0 ± 46 to 29 ± 33 mm Hg, P<0.0004) was noted.

Conclusion:

ASA leads to a hemodynamic and clinical improvement in patients with HCM.

Soft Tissue Amyloidoma in a Patient with Multiple Myeloma

 

Wahed Ishaqsei, MD; Amer Tfaili, MD; Kamal Nasser, MD; Leopoldo Eisenberg, MD

 

Introduction: Amyloidosis represents a heterogeneous group of disorders characterized by abnormal extra cellular deposition of insoluble fibrillar proteinacious material. Amyloidoma, which is an uncommon finding, is defined as localized nodular mass of amyloid deposit with or without systemic amyloidosis.

Case Report: We report a rare case of a 66-year-old woman who presented with right shoulder pain and limping due to left hip pain of few months’ duration and a 7-pound weight loss over 6 weeks prior to presentation. On exam there was tenderness to slight percussion over the left scapula, minimal tenderness to the chest wall, and slight discomfort to the right shoulder, both humeri proximally, and the left groin.

X-rays showed punched-out lesion of the proximal humerus and pelvis consistent with multiple myeloma. Her hemoglobin was 10.2, creatinine 1.6 and 24-hour urine revealed 1226mg bence jones type protein. Bone marrow revealed markedly increased number of atypical kappa restricted plasma cells, with 47% plasma cells of total nucleated cells with normal karyotype. Patient was treated on Zometa, Decadron, Thalidomide and procrit with clinical improvement, but with persistence of left groin pain. An MRI of the groin revealed a 9cm x 6cm x 5cm mass in the left inguinal region with intercapsular extension in the left hip joint with synovial thickening and no bony erosion. A CT-guided biopsy revealed hypocellular lesion in which bland spindled cells were deposited in an amorphous eosinophilic matrix. A Congo red stain revealed an apple-green birefringence under polarized light, consistent with soft tissue amyloidoma. A successful surgical resection was done with good result.

Discussion: Only three reported cases of kappa-light chain Amyloidoma presenting simultaneously with multiple myeloma were found in the English literature. It is important to establish a differential diagnosis of amyloidoma in soft tissue tumor. The clinical presentation mimics other aggressive pathologic processes. The prognosis of amyloidoma is excellent, and cure can be expected by local resection when occurring primarily in a localized anatomic area and no recurrence has been described yet. The therapy of multiple myeloma as in our case, does not affect the course of amyloidoma.

 

 

 

 

 


LOW BONE MASS DUE TO HYPOESTROGENISM IN A PATIENT WITH CARBOHYDRATE DEFICIENT GLYCOPROTEIN SYNDROME.

Cortney V. Jones, MD; Kamal A. Nasser, MD; Gary W. Edelson, MD

Department of Medicine, Sinai Grace Hospital, Detroit, Michigan.

 

BACKGROUND: Carbohydrate Deficient Glycoprotein Syndrome (CDGS) is a rare autosomal recessive condition caused by incomplete glycosylation of plasma proteins. There are less than 200 documented cases of CDGS, with four described types, each caused by a specific enzyme deficiency.

 

CASE REPORT: An eighteen-year-old female with a history of CDGS was referred to an endocrinologist regarding osteoporosis. She had mental retardation, cerebellar hypoplasia, ataxia, pectus deformity, antithrombin III deficiency, and primary ovarian failure.  Serum estradiol, FSH, and LH, done in February 2002, were consistent with postmenopausal values; TSH was normal. In August 2002, a bone density by DXA technique revealed a lumbar spine density of 0.465 gm/cm2 (Z score -5.0).  Femoral neck density was 0.498 gm/cm2 (Z score –3.7). Teriparatide 20 mcg subcutaneously daily was started. In addition, weight bearing exercises were engaged. In May 2004, repeat DXA technique revealed a lumbar spine density of 0.561 gm/cm2 (Z score –4.8).  Femoral neck density was 0.509 gm/cm2 (Z score –3.9). An improvement of 20.6%, 2.2%, and 6.4% in spine, femoral neck, and total hip density respectively was noted with teriparatide therapy, so she was advised to continue it for 24 months and have a repeat DXA scan in 12 months.

 

DISCUSSION: Skeletal abnormalities present in CDGS include: kyphoscoliosis, pectus carinatum, inverted nipples, ankle and hip contractures, and short stature.  In our patient, primary ovarian failure led to decreased attained peak bone mass. The etiology of low bone mass was hypoestrogenism, lack of weight bearing exercise, and inadequate glycosylation of bone proteins. The only reasonable option to increase bone mass was human recombinant parathyroid hormone. Aledronate is indicated in patients with accelerated bone loss, and a hypercogulable state is a contraindication to estrogen therapy. Literature review confirmed the use of DXA technique for bone density assessment in CDGS; however, the use of teraperatide to increase bone mass was novel.             

 

CONCLUSION: The inadequate glycosylation of plasma proteins has systemic effects. Until enzyme supplementation proves to be beneficial, the mainstay of therapy is supportive care.  This entails a meticulous investigation of each organ system and should include bone density assessment.

 

 

 

 

 


Rarest of the Rare Tumor: Primary Leiomyosarcoma of the Sacrum

Department of Internal Medicine, Sinai-Grace Hospital, Detroit Medical Center, Detroit, MI.

 

INTRODUCTION: Primary leiomyosarcoma of the bone is regarded as a rare form of bone sarcoma and thus, few cases have been reported in literature. To our knowledge, this is the second case report of primary leiomyosarcoma involving the spine.

CASE REPORT: A 52 yr old African American female with history of leiomyosarcoma of the sacrum diagnosed and treated with chemotherapy and radiotherapy in 1999, presented to the hospital with complaints of  back pain, weakness in her legs, saddle anesthesia, bladder and bowel incontinence. In the lower limb, there was decreased sensation to pinprick, decreased motor power, and positive babinski bilaterally. She was found to have recurrence few months prior to this admission and was started on chemotherapy. Cord compression was ruled out. Her bone scan did not show any other bone involvement and tissue was negative for C-Kit. Patient was started on gemcitabine, and analgesics. She received in-patient rehabilitation and was given the following options upon discharge: photon therapy, combined radiotherapy and chemotherapy, and sacrectomy.

DISCUSSION: Primary leiomyosarcoma of the bone (PLB) is a rare condition. The origin of the leiomyosarcoma can be one of the following: (1) Primary soft tissue tumor invading the bone, (2) Metastases to bone from leiomyosarcoma, either gastrointestinal tract or uterus, and (3) Primary tumor arising from the bone. Most PLBs are located in the metaphysis of the long bones of the lower extremities. Rarely, it involves the axial skeleton. The origin of the leiomyosarcoma is thought to be from the smooth muscles cells in the intraosseous blood vessels, although an origin from other cells like perivascular, pleuripotent or mesenchymal cannot be ruled out.  Diagnosis of leiomyosarcoma still remains tissue based.  These tumors are usually osteolytic and can be aggressive with interpenetration of the cortical bone.  The lesions have atypical radiographic appearance and can mimic various other primary and secondary malignant tumors.  We are presenting this case report to emphasize that primary leiomyosarcoma of the sacrum, though rare, is associated with mortality as high as 50% with a median survival of 3.4 years after diagnosis. Therefore, clinicians should take an aggressive approach in diagnosing as well as treating this condition.

 

 

 

 

 


Effects of Free Fatty Acid on Glomerular Mesangial Cell Viability and Extracellular Matrix Protein Expression

Aamir Memon, MD, Lalit P. Singh, PhD, and Errol D. Crook, MD. Wayne State University School of Medicine and John D. Dingell VA Medical Center, Detroit, Michigan.

Diabetes and insulin resistance are marked by the presence of hyperglycemia and high serum free fatty acids (FFA). High glucose condition has been shown to cause changes in mesangial cells of the kidneys via different pathways including the Hexosamine Biosynthesis Pathway (HBP). There are limited studies on the effects of high free fatty acids on mesangial cell survival and matrix protein expression under normal or high glucose conditions. To address these questions, we employed tissue culture techniques using a mouse mesangial cell line (MES-13), and exposed them to different concentrations of free fatty acids. Different techniques such as MTT (absorbance) and CyQuant (Fluorescent) assays were used to measure cell viability and proliferation rates. SDS-polyacrylamide gel electrophoresis and Western blots were also performed to detect laminin, a glycoprotein component of ECM, on MES-13 extracts. We used palmitate (saturated fatty acid) and oleate (unsaturated fatty acid) bound to bovine serum albumin (BSA) used as a carrier protein, and used BSA as our standard. MTT assay was performed in a 96 plate well, after incubating MES-13 cells with FFAs for 48 h using, in a Gemini absorbance microplate reader. Similar technique was used was used to calculate nucleic acid content of the cells exposed to FFA by CyQuant assay in 24, 48 and 72 hours. The addition of 0.25 mM palmitate to mesangial cells in culture showed decreased cell viability and proliferation when compared to the control either at normal (5.5 mM) and high glucose (25 mM) conditions. However, the nucleic acid content was marginally increased though the effect was not significant. The effect of Oleate on either MTT or CyQuant was similar to that of the palmitate. Palmitate enhanced the production of laminin-g1 subunit pointing to increase matrix production in glomerular mesangial cells. These results show, though preliminary, that free fatty acids alter some functions of mesangial cells contributing to the development of diabetic nephropathy.

 

 

 

 

 


SULPHASALAZINE INDUCED PULMONARY TOXICITY

Rama Nadella, MD, Associate, Jayasree Grandhi, MD, Associate, Ahmed Ghabsha, MD, Associate, and , Rajika Munasinghe MD, Fellow, Sinai-Grace Hospital/Wayne State University, Detroit, Michigan.

INTRODUCTION: Sulphasalazine is widely used in the treatment of Inflammatory Bowel disease (IBD) and Rheumatoid arthritis (RA). Pulmonary toxicity due to Sulphasalazine is rare. The most common pulmonary complication is hypersensitivity pneumonitis with or without eosinophilia. Fibrosing alveolitis, bronchiolitis obliterans and non-cardiogenic pulmonary edema are also reported. Differentiating Sulphasalazine induced lung toxicity from pulmonary manifestations of IBD can be difficult.

CASE REPORT: A 60 year old female with past medical history of ulcerative colitis, was admitted to the hospital with progressive difficulty in breathing, chest pain, fever, 13 pound weight loss over one month and failure to respond to multiple trials of antibiotics. She was on Sulphasalazine 500mg four times a day.  She had bilateral inspiratory crackles and chest X-ray showed lower lobe infiltrates. The possibilities of tuberculosis, malignancy and interstitial pneumonitis secondary to active IBD were considered and excluded by transbronchial biopsy, bronchio-alveolar lavage and colonoscopy with biopsy. Lung biopsy results showed non-specific interstitial pneumonitis. Discontinuation of Sulphasalazine resulted in a relapse of her IBD and treatment with steroids and 5-amino salicylic acid (5-ASA) was initiated. Her symptoms and infiltrates on chest X-ray resolved in 6-8 weeks.

DISCUSSION: Pulmonary toxicity of Sulphasalazine is attributed to Sulphapyridine and can occur within one to six months of exposure and even up to six years later. IBD can itself cause lung manifestations such as pulmonary vasculitis, chronic bronchitis, and bronchiectasis and bronchiolitis obliterans. The rapid resolution of symptoms in this patient after Sulphasalazine withdrawal and treatment with steroids is consistent with the diagnosis of delayed hypersensitivity reaction due to Sulphasalazine. The definite way to establish causality is to re-challenge with Sulphasalazine. However, due to prior case reports of fatal pulmonary toxicity associated with Sulphasalazine and the availability of safer 5-ASA agents as alternative therapy for IBD, re-challenge with Sulphasalazine was not attempted.

EFFICACY OF NON-PHARMACOLOGICAL MODALITIES TO TREAT DEMENTIA

BACKGROUND : Gingko biloba (Gingko) has been used medicinally for over one thousand years. Ginkgo represents one of the most studied and commonly used herbal remedies for Dementia. Vitamin E has been tried in the treatment of Demetia as it is an anti-oxidant scavenging toxic free radicals.

DATA SOURCES : Medline database from 1985 – 2004 using PubMed and Ovid.

STUDY SELECTION : Gingko: Randomized controlled trial by Le Bars (N-309) and Metaanalysis conducted by Le Bars using only well conducted randomized trials since 1989 (Eg: Le Bars, Kanowski, Maurer and Hofferberth analyses) were studied to see whether Gingko works over Placebo in cognitive disorders, and if it works, how safe is it in treatment of Dementia.

Vitamin E: Sano 1996 is a double blind randomized trial (N-341), which showed effect of a-tocopherol compared with Placebo in the treatment of Alzheimers disease.

OUTCOME MEASURES:     

Gingko => Outcome evaluation was done at 12, 26 and 52 weeks, wherein higher the score poorer the function.

1. ADAS – Cog (to assess memory, language and orientation)

2.GERRI (to assess daily living and social behavior)

3.CGIC (to assess general psychopathology)

Vitamin E => Survival time to the first of four end points :

1.   Death    2.   Institutionalization    

3.Severity of Dementia  4.   Loss of 2 out of 3 basic activities of daily living.

RESULTS:

Gingko: The primary outcome measures were analyzed using intent-to-treat analysis showing a significant improvement in ADAS-Cog score and GERRI score with a p-value < 0.05. No difference was seen in CGIC score.

Vitamin E: There appeared some benefit from Vitamin E with fewer participants reaching end point (only 58%), showing a Peto odds ratio of 0.49 (95% CI 0.25 – 0.96). Moreover, there were excess of falls in Vitamin E group compared to Placebo.

CONCLUSION: Gingko is safe and appears capable of improving cognitive performance and social functioning of Demented patients for 6 months to 1 Year.There is insufficient evidence of efficacy of Vitamin E in the treatment of dementia.

 

 

 

 

 


SEVERE SYMPTOMATIC HYPOCALCEMIA DUE TO VITAMIN D DEFICIENCY PRESENTING AS TETANY.

Padmaja Naidu, MD, Associate, Wahed Ishaqsei, MD, Associate, Rajika Munasinghe, MD, Fellow, Dept. of Medicine, Sinai-Grace Hospital, Wayne State University, Detroit, Michigan

Introduction: Vitamin D deficiency is increasingly recognized as an important cause of osteomalacia, osteoporosis and fracture in adult patients with limited exposure to sunlight and reduced dietary intake of Vitamin D. Most patients are asymptomatic except for an increased risk of fracture. Severe symptomatic hypocalcemia is rare. Patients with Vitamin D deficiency should be evaluated for additional predisposing conditions when they present with severe hypocalcemia.

Case Report: We present a 54 year old female with who presented to our emergency department with involuntary jerks in all four extremities. She had a past medical history of chronic renal failure secondary to obstructive nephropathy from bladder cancer treated by cystectomy and urostomy, history of partial gastrectomy for peptic ulcer disease, diabetes mellitus, breast cancer and osteoporosis. She was significantly debilitated from her multiple medical conditions and reported only very limited exposure to sunlight. She was found to have severe hypocalcemia ( calcium 4.3 mg/dL) and  renal insufficiency (creatinine 2.9 mg/dL). She also had elevated serum parathyroid hormone levels (PTH 187 pg/ml) along with low 25 OH Vitamin D levels(<5ng/ml). The serum, 1,25(OH) Vitamin D was normal (25 pg/ml).

Discussion: Severe hypocalcemia with tetany is a rare complication of Vitamin D deficiency and is usually associated with the concurrent presence of other risk factors. Our patient had previously undergone a partial gastrectomy, which contributes to malabsorption of fat and fat solvable Vitamins such as Vitamin D. She also had renal insufficiency although the normal levels of serum 1,25(OH) Vitamin D, suggest that renal conversion of 25(OH) Vitamin D to 1,25(OH) Vitamin D was probably not affected to a significant extent. The combined presence of Vitamin D malabsorption and inadequate sunlight exposure contributed to the severity of hypovitaminosis D and resulting hypocalcemia in our patient. It is important to recognize patients at risk of Vitamin D deficiency and institute adequate dietary supplement of calcium and Vitamin D to prevent serious skeletal and metabolic complications.

 

 

 

 

 


IMPACT OF LONG TERM USE OF INHALED CORTICOSTEROIDS ON BONE MINERAL DENSITY

Padmaja Naidu, MD, Associate, Sinai-Grace Hospital, Wayne State University, Detroit, Michigan

Research Question:

Does long term use of inhaled corticosteroid decrease bone mineral density?

Data Source:

Pubmed, Ovid Medline 1966 to 2004 July 01

Study Selection: Randomised trials were identified by Medline search term “Inhalation Steroids” and “Bone mineral density”. One Meta-analysis and two randomized controlled trials were selected for  study,  out of 143 search results found. Out of these three, only the meta-analysis was accepted for present study as other two had incomplete follow up of patients. In the meta analysis selected, published and unpublished articles were identified using Medline and Embase databases.

Data Extraction: Studies reporting BMD among adult asthma and COPD patients using Inhaled steroids(ICS)  and non-ICS controls were identified. Studies selected for review included at least 1 year of follow up. Two independent reviewers evaluated studies, data from those meeting specified inclusion criteria were abstracted for inclusion  in the meta-analysis.

Results: In the meta-analysis, 266 studies were reviewed, out of which fourteen(5.3%)  met specified inclusion criteria. Sufficient data was available to perform meta-analysis on 3 measures for ICS using patients (lumbar, femoral neck and major trochanter BMD)  and one measure(lumbar BMD)  for non-ICS using controls. Using current National Asthma Education and Prevention Program definitions, the majority of studies (12 of 14) included patients receiving moderate to high doses of ICSs. Among ICS users, annual changes from baseline in lumbar, femoral neck and major trochanter BMD(-0.23%, -0.17%, and +1.46% respectively) were not statistically significant for subgroups of patients with asthma or COPD. Mean change in lumbar BMD were also not significantly different from controls(-0.02%). Further annual changes in lumbar BMD were not significantly  different for subgroups of patients with asthma or COPD.

Conclusions: Long term use of ICSs in patients with asthma or COPD was not associated with statistically significant changes in BMD.

INTRODUCTION: Torsades de pointes (Tdp) represents a type of polymorphic ventricular tachycardia associated with the long QT syndrome. Antiarrythmics, antihistamines, macrolide antibiotics, and psychotropics are the major drug classes associated with Tdp. We are reporting a case of levofloxacin-induced recurrent episodes of Tdp in a young female with ESRD and CHF.

CASE REPORT: A 37 year old Caucasian female came with an infected indwelling hemodialysis catheter. She received one dose of levofloxacin 500mg intravenously (IV) in ED and another dose two days later. Because of sepsis and respiratory failure, the patient was transferred to the intensive care unit on mechanical ventilation. Within nine hours of the last levofloxacin dose, she had recurrent episodes of Tdp in association with prolongation of the QTc interval from 395 ms at presentation to 525 ms at onset of the first Tdp. Each episode required immediate nonsynchronized electric defibrillation. IV magnesium sulfate was given and levofloxacin was discontinued, but these episodes persisted. Serum levofloxacin concentration was 3 then 1.2 mcg/ml at 6 and 12 days respectively (therapeutic range 0.6 – 6.4 mcg/ml). After the addition of isoproterenol, Tdp episodes became self terminating and less frequent with normalization of the QTc interval. Patient was discharged 25 days later in stable condition with a levofloxacin level of < 0.5 mcg/ml, and QTc of 398 ms.

DISCUSSION: Levofloxacin is renally cleared, with 80-90% of the dose excreted unchanged in the urine. Its half-life extends from approximately 6 hours in patients with normal renal function to greater than 35 - 72 hours in patients with ESRD, and it is not removed to any significant extent by hemodialysis. Only two cases of levofloxacin-induced Tdp have been reported in the literature none of which was recurrent. The persistently elevated concentration of the drug 6 and 12 days following the last dose of levofloxacin might explain the recurrence of Tdp.

CONCLUSION: Caution has been advised with the use of levofloxacin in patients with risk factors for Tdp such as heart disease, electrolyte disturbances, and concomitant use of other QT-prolonging drugs. This case calls for more caution to be exercised when these patients also have ESRD due to the longer levofloxacin half-life which could render a possible Tdp recurrent. 

 

 

 

 

 


POST TRANSPLANT GLOMERULOPATHY IN HEPATITIS C POSITIVE

PATIENTS WITH RENAL ALLOGRAFTS

 

Vibha Nayak, MD, Abdolreza Haririan, MD, Jose-Marie El-Amm, MD, Department of Medicine,Sinai-Grace Hospital/Harper Hospital, Detroit Medical Center, Wayne State University, Michigan.

 

 

Little is known about risk factors for development of post transplant glomerulonephritis (GN) in Hep C+ kidney transplant (KT) recipients. The records of 41 Hep C + patients transplanted between 9/98 and 5/04 and followed for 2 yrs (median) were reviewed. The induction and maintenance agents used in conjunction with Mycophenolate Mofetil were steroids,Calcineurin Inhibitors(CI),Sirolimus and Interleukin-2 receptor antibodies(IL-2R). Transplant glomerulopathy in 2 pts, was not considered a GN variant. Association between GN and different variables were examined using x2 or t-test, as appropriate. P<0.05 was considered as significant. Patient characteristics were their age, race, sex, number of years on hemodialysis, presence of coronaty artery disease, delayed graft function(DGF), Donor Hep C status, the use of steroids, calcineurin inhibitors, interleukin-2 receptor antibodies, and sirolimus.

Five pts (12%) developed membranoproliferative/membranous GN (MPGN/MGN) and 9 (22%)developed focal segmental glomerulosclerosis(FSGS). Fourteen pts (34%) experienced acute rejection (AR). Donor Hep C status, DGF, and CI use were not associated with GN. We observed that post transplant GN occurs in one-third of Hep C+ KT recipients, with FSGS accounting for two-thirds of these cases in our predominantly African-American population. There was an association between use of maintenance steroid and IL-2R antibody induction with development of FSGS, and also between Sirolimus use and AR with development of MPGN/MGN.

                    

 

 

 

 


Scleroderma Renal Crises in Pregnancy

Asmita Patel, MD, Associate, Amer Tfaili, MD, Associate, Ramesh Kotihal, MD, Associate, Kamal Nasser, MD, Member, Department of Internal Medicine,

Sinai-Grace Hospital/Detroit Medical Center, Wayne State University, Detroit, Michigan.

 

Introduction: Scleroderma is an uncommon systemic disease, which affects 1 to 2 per 100,000 individuals in the USA. Scleroderma renal crisis (SRC) develops in 10 to 15% of patients with early diffuse cutaneous scleroderma. In the pregnant patients, however, it is difficult to distinguish hypertensive crisis due to SRC from that secondary to eclampsia.

Case Report: A 32 year-old pregnant African-American female with gestational age of 35 weeks, and past medical history of diffuse cutaneous scleroderma, diagnosed one year prior to presentation, presented to the emergency department (ED) with two witnessed tonic-clonic seizures and elevated blood pressure. Patient was diagnosed with eclampsia and managed with intravenous magnesium sulfate and hydralazine followed by an emergent cesarean section. Postpartum, her renal function progressively worsened and blood pressure remained uncontrolled. This was attributed to eclampsia, and the blood pressure was managed with esmolol and hydralazine. An ACE inhibitor was also added to this treatment regimen. Patient’s renal function continued to deteriorate with a rise in creatinine levels from 1.8 to 3.3 mg/dl. ACE inhibitor was withheld, which was followed by further elevation in creatinine levels to 9.8 mg/dl along with anuria. This deterioration in renal function was thought to be due to SRC and ACE inhibitor was reintroduced at that time. Hemodialysis was eventually initiated for signs of volume overload. Patient was discharged home in a stable condition.

Discussion: In pregnant patients, it is difficult to distinguish hypertensive crisis due to SRC from eclampsia. The cutaneous manifestations of scleroderma help this distinction to a certain extent. Liver function tests, which are usually normal in SRC and elevated in eclampsia, and the fast deterioration of renal function in SRC could also be helpful clues. In patients with scleroderma who develop eclampsia, therapy with ACE inhibitors, particularly captopril, has been shown to improve survival and shorten the duration of dialysis (1-year survival: 15% without and 76% with ACE inhibitors). ACE inhibitors should be promptly initiated and maintained in the postpartum period. Despite initiation of ACE inhibitor therapy, poor outcome is associated with an uncontrolled blood pressure, congestive heart failure, and initial serum creatinine more than 3.0 mg/dl.

Introduction: Prostate cancer is the second most common malignancy in males in the United States. Bone metastases occur in about 65% to 75% of patients with advanced prostate cancer, typically involving the lumbar spine, ribs, and pelvis. Involvement of skull convexity is frequent, but skull base and orbits are rarely affected. We report a rare case of orbital wall metastasis from a prostate cancer.

Case Report: A 66-year-old Caucasian male was diagnosed with prostate cancer seven years prior to this presentation, when he underwent a prostatectomy for acute urinary retention, and outlet obstruction. Bone scan had showed a left tabular and lumbar vertebral lesion. Patient was believed to have metastatic disease, and was treated with radiation therapy. Five years later, a repeat bone scan revealed multiple lesions, notably a right periorbital lesion. Combined androgen blockade therapy was started. He discontinued his hormonal therapy after a total of six months, and did not seek follow-up care.

During this presentation, patient had diminished visual acuity, right eye pain and difficulty in depth perception. There were no other painful sites, neurological changes or constitutional symptoms. Patient had developed proptosis, and orbital nerve compression was suspected. MRI of the orbits showed a 2 cm lesion in the posterolateral right orbital wall compressing the optic nerve. Bone scan and computed tomography (CT) of abdomen and pelvis showed extensive skeletal and skull involvement, along with metastatic disease of the lung parenchyma and pancreas. Patient was restarted on combined androgen blockade therapy (Depo-Luprolide and Casadex). Vision in the right eye was restored, and patient remained in stable condition.

Discussion: Metastases of prostate carcinoma to the orbit are rare. Cancer of breast and lung, lymphomas, and leukemia are amongst the commonest primary neoplasms known to metastasize to the orbit. The mean age at the onset of symptoms is greater for patients with orbital metastasis secondary to prostate cancer as compared to those with other orbital metastases (70.1 versus. 53.6 years). Prostate metastases to the orbit frequently present as osteoblastic lesions, whereas other orbital tumors present as osteolytic lesions or soft-tissue masses. Clinical history, high resolution CT scan, MRI as well as immunoperoxidase staining for cytoplasmic acid phosphatase can help establish the diagnosis of prostatic orbital metastases. Testosterone determines the rate of tumor growth in most cases. Consequently, hormonal manipulation has been shown to alter the course of systemic disease. A workup of osteoblastic orbital lesion should include a urologic evaluation since metastatic lesions from prostate carcinoma have good response to androgen blockade.

Surgical management of a lung abscess : A Review

Asmita Patel, MD, Associate, Department of Internal Medicine,

Sinai-Grace Hospital/Detroit Medical Center, Wayne State University, Detroit, Michigan.

Question:  After failure of optimal antibiotic therapy in patients with a lung abscess, what are the benefits of surgical intervention?

 Data Sources:  Data was collected by searching Medline, Pubmed, and Cochrane library from 1980 to 2004, using the search terms "lung abscess" and "pulmonary abscess". Different modes of surgical interventions available were reviewed.

 Methods:  A retrospective analysis of the patients who underwent lobectomy was studied.  A review of literature also revealed four case series, which studied various modes and efficacy of surgical management of lung abscess.  The outcome measures studied in these case series included the cure rate, rapidity of recovery, and residual defects. No randomized control trials were found.

 Results:  The cure rate with lobectomy was 81% and mortality was reduced to 14%. Patients with percutaneous mode of drainage also had comparable cure rates, but had slower resolution requiring up to 30 days. The mean duration of hospital stay was 10 days with percutaneous drainage, compared to 21 days with lobectomy.

 

 

 

 

 


SPONTANEOUS KIDNEY RUPTURE IN A DIALYSIS PATIENT

Department of Internal Medicine, Sinai-Grace Hospital, Detroit Medical Center, Wayne State University, Detroit, MI.

 

INTRODUCTION: Spontaneous subcapsular or perinephric bleeding of the kidney is an uncommon clinical scenario. Acquired cystic kidney disease (ACKD) is one of the rare causes of such bleeding. It is frequently oligosymptomatic and thus needs a high level of suspicion for the diagnosis. We present a case of ACKD complicated by perinephric hemorrhage.

CASE REPORT: A 62 year-old male with past medical history of ESRD on hemodialysis (HD), hypertension and hepatitis C was transferred from his dialysis center due to sudden onset of a right sided flank pain during HD. The pain was dull aching, severe 10/10 in intensity, non-radiating and not associated with any aggravating or relieving factors. The patient usually made little urine daily and had noticed a reddish discoloration of his urine one day prior to admission. He denied any fever or chills, history of trauma, kidney stones or bleeding diathesis. On admission, the patient was hemodynamically stable and had minimal right flank tenderness. The rest of his exam was non-revealing. His hemoglobin was 14.9mg/dl and hematocrit was 44.6 %. A computed tomography of his abdomen and pelvis revealed multiple cysts in both kidneys and a perinephric infiltration around the posterior aspect of the right kidney suggestive of a retroperitoneal hemorrhage. The patient was admitted to the medical floor and the urology service was consulted. His condition was closely monitored for any signs of extension of the retroperitoneal bleeding with serial hemoglobin concentrations and renal ultrasound imaging. The bleeding proved to be stable so the patient was managed conservatively and later discharged home in stable condition to follow-up with the urologist as an outpatient.

CONCLUSION: ACKD is a complication of long standing ESRD and is almost the rule after 10 years of HD independent of the cause of the renal failure. Intracystic or retroperitoneal bleeding is one of the main complications in addition to neoplastic transformation in these patients. Early diagnosis of such a bleed with an imaging study is essential to prevent a life-threatening bleeding. Non-massive bleeding in a hemodynamically stable patient is managed conservatively and nephrectomy is indicated for severe hematomas and in cases where malignancy is suspected.

 

 

 

 

 


Orthostatic Hypotension; is it a sign of post concussion syndrome?

S. Rajaguru, M.D (Associate), A. Reddy M.D (Associate), S. Marur MD (Member), Department of Medicine, Sinai Grace Hospital/Wayne State University, Detroit, Michigan.

Background: Patients sustaining mild traumatic brain injuries often report physical, cognitive, and emotional or behavioral symptoms referred to as post concussion syndrome (PCS).

Case report: A 35-year-old African American male with no significant past medical history presented to Sinai Grace emergency department for new onset seizures after sustaining a closed head injury from “pistol whipping”. He developed seizure activity in the emergency department as well. Initial presentation revealed a 2.5 cm laceration to the border of his parieto-occipital area with hematoma on the inferior aspect of his left occipital area. During the hospital stay, the patient continued to have seizure, headache, anxiety, and symptomatic orthostatic hypotension, which did not respond to IV fluid boluses. Further, the orthostasis did resolved with fludrocortisone treatment.

Discussion: The most commonly reported post concussion symptoms are headache, dizziness, decreased concentration, memory impairments, irritability, fatigue, visual disturbances, sensitivity to noise, judgment impairments, depression, and anxiety. However the occurrence of autonomic dysfunctions like orthostatic hypotension following head trauma in the absence of other causes such as hypovolemia is not documented thus far.

Conclusion: Here we would like to announce the first reported case of autonomic dysfunction presenting as orthostatic hypotension with post concussion syndrome.

 

 

 

 

 


Efficacy of Trnscutaneous Pacing in Asystole.

S. Rajaguru MD (Associate), S. Marur MD (Member) Department of Medicine, Sinai Grace Hospital/ Wayne state University, Detroit, MI

 

Background: Asystole is the absence of electrical activity in the myocardium. Confirmation of the rhythm is crucial in the management of Asystole. Transcutaneous pacing (TCP) is the electrical stimulation from pads placed on the body to stimulate heart contraction. This is indicated as an emergency temporary solution to improve asystole, a slow heart rate with inadequate cardiac output. The aim of this study is to identify the efficacy of transcutaneous pacing in Asystole management.

Method: Extensive literature search was carried out on the studies done on asystole from 1980 onwards. Ovid and Pub med search were done using asystole and transcutaneous pacing as keywords. Selection criteria were randomized controlled prospective studies with reasonable number of population. Six studies were selected based on the selection criteria.

Results: Three out of these studies were done in pre-hospital settings. Two studies were conducted in the emergency department and the other study was carried out in in-hospital. All the studies done in pre-hospital setting came to a similar conclusion.

Conclusion: Out of hospital studies concluded that transcutaneous pacing does not improve the survival of the patient with asystolyic cardiac arrest. In-hospital studies basically concluded that TCP should be done early enough to have a satisfactory out come.

Discussion: Asystole occurs due to several underlying conditions. However, the studies done so far have not taken etiology in to consideration. Here we suggest designing a retrospective study conducting on inpatients that develop asystolic cardiac arrest and received TCP as a study group. The control group will be the patients who develop asystolic cardiac arrest but did not receive TCP. Further more this study will analyse the out come considering underlying condition which can be obtained from the medical records.

 

 

 

 

 


A Rare Case of Uremic Enteropathy

M. Reddy, MD, K. Majekodunmi, MD, M. Sklar, MD

Sinai-Grace Hospital, Wayne State University, Detroit, Michigan.

Background: Since the advent of hemodialysis, the long-term complications of uremia have been reduced. But there are rare instances of complications even on patients undergoing Hemodialysis. Among the many organ systems affected by uremia, gastrointestinal tract (GI) tract is most profoundly affected. Some of the clinical manifestations include anorexia, nausea, vomiting, metallic taste in mouth and some times bloody diarrhea1, 2. Studies done prior to the start of dialysis had shown changes in mucosa and submucosa including hemorrhage, ulceration, and pseudomembranous lesions in End Stage Renal Disease (ESRD) patients3, 4. 

Clinical Vignette: We report a rare case of a 33 yr old female with ESRD on hemodialysis for 9 yrs who was not shown to have any changes in the GI tract on Esophagogastroduedunoscopy (EGD) and colonoscopy did show remarkable changes in the small intestine on capsule endoscopy. The patient came to the hospital with complaints of nausea, vomiting and severe diarrhea associated with hematochezia for 24-hrs. The patient had developed ESRD secondary to lupus between ages 18-21, also had other co-morbidities like hypertension, hyperlipidemia, multiple graft placements for hemodialysis, as well as had a renal transplant in Feb 2004. Physical exam was unremarkable except for the presence of vascular grafts. Labs showed a WBC count of 4.5, Hb 10.6, platelets of 151,000, Potassium 5.1, BUN 66 and Cr 11.6. Colonoscopy showed small internal hemorrhoids with a tortuous and redundant colon. EGD showed esophagitis, esophageal ulcers, and non-bleeding erythematous gastropathy with mild nodularity. The living non-related renal transplant did not show any signs of rejection or immune complex mediated process on biopsy. The patient was then scheduled for a capsule endoscopy, which showed multiple sites of hemorrhagic, polypoid folds. The mucosa had a mosaic pattern with absence of villi. These findings were suggestive of enteropathy most probably related to uremia.

Discussion: There has been evidence of motility disorders of the esophagus as a result of ESRD induced neuropathy5, and hemorrhagic gastritis and hemorrhagic duodenitis6. There have not been enough studies to look at the remainder of the small intestine to note chronic changes as a result of ESRD. Our case here represents changes occurring in the small intestine as a result of ESRD. In ESRD patients with iron deficiency anemia with negative EGD and colonoscopy need to further investigation by other means such as capsule endoscopy.

Wireless capsule endoscopy offers an optimal approach for evaluating patients with obscure gastrointestinal bleed. Wireless capsule endoscopy is as or more sensitive than other methods for the diagnosis of small bowel sources of blood loss including push enteroscopy. Its main advantages are that it is noninvasive and permits examination of the entire small bowel, which is not always possible during enteroscopy. Further work however needs to be done to utilize this device in tissue sampling.

 

 

 

 

 


Hypothyroidism: A possible risk factor for Hepatocellular Carcinoma

Arvind Reddy, MD, MPH, (Associate) Sinai Grace Hospital/Wayne State University

Background:

Hepatocellular Carcinoma (HCC) is the fifth most common cancer world wide. While most HCCs are diagnosed in those with a known underlying chronic liver disease, about 25% are diagnosed in patients with no known cause. Most cases of this later group are believed to be a consequence of Non Alcoholic Fatty Liver Disease (NFLD). Hypothyroidism could lead to a series of events such as obesity, hyperlipidemia, insulin resistance and lipid peroxidation which have been implicated in the pathogenesis of NFLD. Studies on rat hepatocytes have shown that triiodothyronine (T3) induces apoptosis by direct action on mitochondria, thus making it plausible that hypothyroidism could play an active role in pathogenesis of HCC. Abnormal liver function tests in patients with hypothyroidism can be reversed by pharmacological correction of their thyroid status, thus widening the therapeutic implications of thyroid replacement. Although an association between hypothyroidism and Non Alcoholic Steatohepatitis (NASH) has been recently suggested, association between hypothyroidism and HCC has not been studied.

We conducted a case control study at the Mayo Clinic, Rochester to evaluate the relationship between hypothyroidism and HCC.

Methods

Subjects were consecutive patients diagnosed with HCC between Jan1, 1999 and March 31, 2004 at the Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester. Cases (n = 54) were patients with HCC in whom an underlying etiology for chronic liver disease (alcohol, infectious, metabolic or autoimmune) could not be detected after detailed history, examination and investigations. Two groups of HCC patients were selected as controls – patients with underlying hepatitis C (n=57) and patients with a history of heavy alcohol consumption (> 60g/week) (n=49).

Data were abstracted from the medical records using structured forms designed for the purpose of the study. Hypothyroidism was defined as TSH level >5.0 or as history of hypothyroidism prior to cancer diagnosis as stated in the medical history or as history of being on thyroid hormone replacement at the time of diagnosis of HCC.

We used multivariate logistic regression to model the relationship between history of hypothyroidism and etiology of HCC, controlling for all possible covariates.

Results

HCC patients with unknown etiology had a greater proportion of females; were more likely to be non-smokers, have a biopsy proven HCC diagnosis, have larger tumors; have an advanced stage of HCC at diagnosis, have symptoms at diagnosis, have a history of hypertension; and were less likely to have cirrhosis; as compared to control HCC patients with underlying hepatitis C or alcoholic liver disease.

Out of the 160 HCC patients in our study, 18 (11 percent) had a history of hypothyroidism. Of those, 12 (67 percent) were in patients with unknown etiology, 2 (11 percent) were in those with underlying HCV and 4 (22 percent) were in patients with alcoholic liver disease. After controlling for covariates, compared to HCC patients with underlying hepatitis C, patients with an unknown etiology were more likely to have a history of hypothyroidism prior to cancer diagnosis (POR: 14.7 , 95% confidence interval: 1.3, 136.27). HCC patients with an unknown etiology were also more likely to have a history of hypothyroidism as compared to patients with underlying alcoholic liver disease, but the result was not statistically significant (POR: 3.95, 95% confidence interval: 0.59, 47.31). When we pooled patients in the two control groups to form a common control group, the patients with unknown etiology were 7.29 times more likely (95% confidence interval: 1.24, 42.76) to have a history of hypothyroidism. These results are adjusted for the effects of age, gender, BMI, smoking status, platelets, tumor size, TNM stage, presence/absence of cirrhosis, screening for HCC, history of diabetes and history of hypertension and features of metabolic syndrome. The adjustment was made in different levels to assess the role of covariates.

Conclusion

We conclude that hypothyroidism may have a role to play in hepatocarcinogenesis and should be further investigated as a potential etiologic agent. If established, it can play an important role in preventive medicine as a reversible cause for HCC especially in patients with no underlying cause for chronic liver disease.

 

 

 

 

 


Role of Diet in Gout

M Reddy, MD

Sinai-Grace Hospital, Wayne State University, Detroit, Michigan.

Background: Gout is a chronic crystal induced arthropathy with an incidence of 20-35/100,000. Hyperuricemia leading to the gouty attacks is controlled by the use of drugs to decrease the production or increase excretion of uric acid. A 21 percent increase in the risk of having gout has been associated with the intake of food having high purine content.

Methods: Several studies were analyzed from OVID Medline. Two trials were selected for this study as they were comparing clinical outcomes versus measuring metabolite levels. The first is a Prospective clinical trial involving 13 patients, the second is a Prospective cohort study involving 47,150 patients in the Health Professionals Follow-up study. Pearson’s Correlation analyses and Relative Risks were used for analysis of the data.

Results: In the first study there was a significant (p=0.002) reduction in number of Gouty attacks from 2.1 attacks per month to 0.6 in patients on a low purine diet for 16 weeks. In the second study it was shown that there was a 21% increased risk of gout with each additional serving of meat a day, and a 7% increased risk with one additional weekly serving of seafood. In this study they also showed that there was no increased risk with purine rich vegetable intake. In both these studies there was a significant decrease in incidence of gouty attacks with reduction of BMI/ body weight and alcohol consumption.

Conclusions: There is convincing evidence about the reduction in the incidence of gouty attacks with reduced consumption of alcohol and a reduction in BMI/ body weight. There is some evidence to show that meat, and seafood intake can cause an increase in number of gouty attacks. However there is no convincing evidence to prove that a reduction in purine rich vegetable intake has any effect on the incidence.

Introduction: Microangiopathic hemolytic anemia is commonly seen after mitral valve replacement. But it is an uncommon complication of mitral valve repair and when it happens it is considered a failure of the valve repair. We present a case of hemolysis after mitral valve repair.

Case Report: A 54-year-old male with prior history of HTN and CHF presented with chest pain, exertional dyspnea and dark urine. Patient had undergone mitral valve repair approximately a month prior to this presentation for severe mitral regurgitation. The surgery was done using 30 mm Carpantier-Edward Physio ring as well as posterior valve resection. Lab results showed normocytic anemia, indirect bilirubinemia, raised LDH (2296 U/l), low haptoglobin (<6mg/dl) and raised creatinine (3 mg/dl). Coombs test was negative and urinalysis showed hematuria 3+blood and 2-5 RBC in urine. The peripheral smear showed schistocytes and polychromasia. Transthoracic echocardiography showed moderate to severe mitral regurgitation .No other cause of hemolysis was identified. Patient underwent reoperation 3 weeks after presentation. Intraoperative findings were dehiscence of the annuloplasty ring and paravalvular leak. The valve was replaced by St. Jude’s prosthetic valve and patient recovered from the surgery without complication. There was complete resolution of the hemolytic process after the surgery.

Discussion and Conclusion: This case is a unique presentation of early mitral valve repair failure. In the English literature 65 such cases have been reported showing development of hemolysis within 3-4 months. The mechanism of hemolysis in our case was attributed to fragmentation of RBC due to regurgitant jets against dehisced annuloplasty ring. In patients with signs and symptoms of worsening CHF with low hemoglobin who have recently undergone mitral valve repair, the etiology may be undergoing hemolysis and warrant reoperation.

Introduction: It is a general practice to send patients home on insulin regimen after an episode of diabetic ketoacidosis (DKA) with eventual switchover to oral hypoglycemics.

Clinical Question: What is the evidence for the use of Oral hypoglycemics in Diabetes mellitus type 2 status post-diabetic ketoacidosis?

Methods: Literature search was conducted utilizing Medline Ovid(1966-2004), Medline PubMed and Cochrane library with DKA, oral hypoglycemics and type 2 diabetes mellitus used as key words. Only double-blinded randomized controlled trials were to be selected.

Results: Only one relevant study meeting the above criteria observed use of oral hypoglycemics in African American patients who presented with severe hyperglycemia and DKA.  The study revealed that over a period of sixteen months, use of low dose sulfonylurea decreased the recurrence of hyperglycemia signifinicantly (p= 0.03), in patients post DKA from 60% to 14% when comparing with patients on diet alone. Assessment of beta-cell function showed improvement in basal and stimulated C peptide levels in patients with history of DKA and became comparable to patients with severe hyperglycemia (P<0.01).

Conclusions: This study was conducted on a select subset of the population and provided evidence that oral hypoglycemics decrease the incidence of hyperglycemic episodes post DKA. . It should be remembered that DKA occurs because of transient and reversible glucotoxicity of islets cell in patients with type two DM. Experts practices reveal a pattern of gradual transition of insulin to oral hypoglycemics , starting with secretogouges than adding other hypoglycemic agents with tapering of insulin over a period of time. Clear guidelines are strongly required. More randomized control studies are recommended to study the efficacy of different oral hypoglycemics agents against insulin in patients post DKA.

 

 

 

 

 


A Rare Presentation of Granulocytic Sarcoma as Isolated Cervical Adenopathy.

Introduction: Granulocytic Sarcoma, also known as Chloroma, is a rare extramedullary solid tumor composed of malignant immature cells of the granulocytic series. It is often misdiagnosed as it can be confused with lymphoma. It has unique cytologic features independent of the site of the tumor.

Case Report:  Our patient is a 55-year-old African American gentleman with a known history of metastatic prostate cancer and pancreatitis, who presented to the emergency department with abdominal pain, nausea and vomiting. On neck exam, he was found to have 4 masses which were hard, mobile, painless, each measuring approximately 3x4 cm. Lungs were clear. Abdominal exam revealed distension, positive bowel sounds, and diffuse tenderness without guarding or rebound. CBC and chemistry was within normal limits except for elevated alkaline phosphatase and AST. Peripheral smear was normal. Chest and abdominal x-rays revealed blastic disease of the dorsal spine and pelvis. A fine needle aspirate of a neck mass revealed numerous cells with increased nuclear/cytoplasmic ratio. The differential diagnosis was malignant lymphoma, poorly differentiated carcinoma or granulocytic sarcoma. Further analysis showed sheets of cells composed of myeloblasts, promyelocytes, myelocytes, mature neutrophils, numerous mitosis and occasional monocytes. Immunologic staining was positive for myeloperoxidase, lysozyme, CD68, synaptophysin and chromogranin. These findings strongly suggest a diagnosis of granulocytic sarcoma. The following stains were negative: pancytokeratin, leukocyte common antigen, vimentin, S100, CD3, CD10, CD20, CD34, and CD 43. These findings make lymphoma unlikely.

Discussion and Conclusion: Granulocytic sarcoma is a rare extramedullary solid tumor composed of malignant immature cells of the granulocytic series. It usually occurs in patients with acute myelogenous leukemia. Isolated chloromas, in the absence of acute myelogenous leukemia, are rare. The diagnosis of granulocytic sarcoma is difficult in the absence of abnormality in the peripheral blood or bone marrow. Hence histopathologic findings should be evaluated before a diagnosis of malignant lymphoma is pronounced. Granulocytic sarcoma has poor prognosis. One study showed that administration of intensive chemotherapy similar to that used to treat acute nonlymphoblastic leukemia, is associated with a significantly lower probability of developing acute myeloid leukemia and prolongs survival.
