On Pump Coronary Surgical Revascularization In A Patient With Chronic Immune Thrombocytopenic Purpura, Saulat Fatimi, Danesh K Kella, Marium Muzaffar, Hashim Muhammad Hanif

Section of Cardiothoracic Surgery

We performed on-pump coronary artery bypass graft surgery on a 54-year-old female, known case of chronic Idiopathic Thrombocytopenic Purpura (ITP), hypertension and dyslipidaemia who had presented to us with progressive exertional shortness of breath and chest pain. The decision of going on with CABG was made after two weeks of preoperative treatment with prednisolone. Her platelet counts pre-operatively and on the 4th post-operative day were 135 x 10(9)/L and 32 x 10(9)/L. She had an unremarkable post-operative recovery, without requiring whole blood or platelet transfusions. We recommend preoperative steroid treatment in patients with chronic ITP undergoing CABG.

Department of Pathology and Laboratory Medicine

OBJECTIVE: To report trends of extended spectrum beta lactamase (ESBL), multidrug resistant (MDR) ESBL and emergence of carbapenem resistant ESBL producing isolates of K. pneumoniae from Pakistan.

METHODS: Retrospective analysis of laboratory data was conducted (2002-2007). K. pneumoniae were isolated and identified from clinical samples using standard microbiological techniques. Antimicrobial susceptibility testing was performed by Kirby Bauer. ESBL was detected using combined disc method. Statistical analysis was performed using SPSS version 13.

RESULTS: 15914 K. pneumoniae isolates (2002-2007) were analyzed. Significant increase in ESBL and MDR ESBL producing K. pneumoniae (p = or < 0.0001) was observed. We found significant association of ESBL positive K. pneumoniae with age less than 10 years, males and blood isolates (p = 0.001). 0.4% (n=23) of ESBL positive isolates were carbapenem resistant.

Hepatitis D: Scenario In The Asia-Pacific Region, Z Abbas, Wasim Jafri, Sajjad Raza

Department of Medicine

Hepatitis D virus (HDV) infection is present worldwide and affects all age groups. Around 18 million people are estimated to be infected with HDV. An important trend in HDV infection is global decline. HDV prevalence has decreased significantly in Europe since the 1970s and 1980s when it was first reported. The Asia-Pacific region now seems to be where HDV is a major health concern. There is a lack of available data from most of the countries from this region, hence, the true status of HDV cannot be determined. In South Asia, most of the countries have conditions that are favorable …

Antibiotics In Acute Necrotizing Pancreatitis: Perspective Of A Developing Country, Afrasyab Khan, Sadaf Khan

Section of General Surgery

Prophylactic antibiotics in acute necrotizing pancreatitis is controversial. The mortality of acute necrotizing pancreatitis is 8-25% in the western world. In view of the limited resources available for managing the complications of infected pancreatitis in developing countries, the use of prophylactic antibiotics may be recommended in selected cases.
Various antibiotics show good penetration into the pancreatic tissue; imipenem and quinolones have better penetration. Clinical trials on the use of prophylactic antibiotics in necrotizing pancreatitis have been reviewed.
Prophylactic antibiotics have been considered if greater than 30% pancreatic necrosis as documented by CT scan. Imipenem can be given for a duration …

Ganglionic Plexus Ablation During Pulmonary Vein Isolation--Predisposing To Ventricular Arrhythmias?, Faizel Osman, Suman Kundu, Jiun Tuan, Jeilan Mohamed, Peter J. Stafford, G. Andre' Ng

Internal Medicine, East Africa

Catheter ablation is increasingly used to treat patients with atrial fibrillation (AF). Ablation of ganglionic plexi is often performed to reduce vagal innervation and has been shown to confer a better long-term outcome in terms of AF recurrence. We report a case of a patient having AF ablation with a profound vagal response, suggesting ganglionic plexus ablation, who subsequently developed ventricular fibrillation after programmed ventricular stimulation. Reduced vagal modulation is known to predispose to ventricular arrhythmias and vagal denervation following AF ablation may predispose to ventricular arrhythmias and requires further study.
