Cephalosporin Resistant Shigella Flexneri From A Clinical Isolate--A Rare Finding, Nasim Sabir, Afia Zafar
Department of Pathology and Laboratory Medicine
Shigellosis is an important public health problem, especially in developing countries. Antibiotic treatment of dysentery aimed at resolving diarrhea or reducing its duration, and to prevent transmission to other close contacts. Isolates with resistance to first line drugs have been reported throughout world, third generation cephalosporins and quinolones are mainstay of treatment. Shigella flexneri resistant to third generation cephalosporins in a clinical isolate is a rare finding, and this has been reported for the first time in Pakistan.

Vi Antigen Expression In Salmonella Enterica Serovar Typhi Clinical Isolates From Pakistan, John Wain, Deborah House, Afia Zafar, Stephen Baker, Satheesh Nair, Claire Kidgell, Zulfiqar Bhutta, Gordon Dougan, Rumina Hasan
Department of Pathology and Laboratory Medicine
The accurate identification of Salmonella enterica subsp. enterica serovar Typhi variants that fail to express the capsular polysaccharide, Vi, is an important and much discussed issue for medical microbiology. We have tested a multiplex PCR method which shows the presence or absence of the genetic locus required for Vi expression. Of 2,222 Salmonella serovar Typhi clinical isolates collected from patients' blood over a 4-year period in a region of Pakistan where typhoid is endemic, 12 tested negative for Vi expression by serological agglutination. However, only 1 of these 12 was Vi negative by the multiplex PCR method. This result was …

Smoking Prevalence, Knowledge And Attitudes Among Medical Students In Karachi, Pakistan, F M. Khan, S J. Husain, A Laeeq, A Awais, S F. Hussain, J A. Khan
Section of Pulmonary & Critical Care
A survey of smoking prevalence and attitudes was made among medical students randomly selected from classes at the Aga Khan University, Karachi, Pakistan. Of 271 respondents, 14.4% were current smokers (22.0% male and 3.8% females) and 3.3% ex-smokers. A majority of students recognized the dangers associated with active as well as passive smoking although only 55% of current smokers planned to quit in the near future. Most smokers (96%) believed that they as well as other health professionals needed training on smoking cessation and 95% of all students believed that doctors should play a role model in smoking cessation by …
Solid And Cystic Epithelial Neoplasm Of Pancreas With Metastasis: Report Of A Highly Unusual Case, Zubair Ahmad, Nausheed Yaqboob, Suhail Muzaffar, Nadeem Ahmad
Solid And Cystic Epithelial Neoplasm Of Pancreas With Metastasis: Report Of A Highly Unusual Case, Zubair Ahmad, Nausheed Yaqboob, Suhail Muzaffar, Nadeem Ahmad
Department of Pathology and Laboratory Medicine
Solid and cystic papillary epithelial neoplasms of the pancreas are uncommon tumors occurring predominantly in young women. These tumors have excellent prognosis and after complete surgical resection, more that 95% patients are cured. Occasionally, they invade the surrounding pancreatic parenchyma. These tumors can recur even many years after resection, so long-term follow up is essential. Very few cases metastasize. We present a case of a middle aged woman with metastases to liver and omentum
Drug Related Critical Incidents, F A. Khan, M Q. Hoda
Drug Related Critical Incidents, F A. Khan, M Q. Hoda
Department of Anaesthesia
Drug related incidents are a common form of reported medical errors. This paper reviews the critical incidents related to drug errors reported from the main operating theatre suite in a teaching hospital in a developing country from January 1997 to December 2002. Each report was evaluated individually by two reviewers using a structured process. During this period, 44 874 anaesthetics were administered; 768 critical incidents were reported, 165 (21%) of which were related to drug errors. Underdosage, side-effect/drug reaction and syringe swap were the most common. A total of 76% were classified as preventable; 56% due to human error and …

Department of Pathology and Laboratory Medicine
Objective: To provide frequency and distribution pattern of various types of irregular red cell alloantibodies in patients with thalassemia major.
Methods: This is a descriptive study conducted at two centers from January to December 2001. Purposive sampling was done and all patients diagnosed to have thalassemia major were included in the study. Antibody identification was carried out on serum employing commercial two-cell panel using standardized blood bank methods. If patients were found to have an irregular red cell alloantibody then the antibody identification was performed using 16 panel cells. Results: A total of ninety-seven patients were included …
Anaphylactic Reaction After Intramuscular Injection Of Cyanocobalamin (Vitamin B12): A Case Report, Fareena Bilwani, Salman Adil, Usman Sheikh, Ayesha Humera, Mohammad Khurshid
Anaphylactic Reaction After Intramuscular Injection Of Cyanocobalamin (Vitamin B12): A Case Report, Fareena Bilwani, Salman Adil, Usman Sheikh, Ayesha Humera, Mohammad Khurshid
Department of Pathology and Laboratory Medicine
We report a case of anaphylactic reaction to intramuscular injection of cyanocobalamin. This 52-year-old lady was diagnosed as a case of megaloblastic anemia secondary to dietary vitamin B12 deficiency. She had severe anaphylactic reaction after the parenteral administration of cyanocobalamine. Later she received oral vitamin B12 with no adverse effects. The purpose of this case report is to draw attention to the hypersensitive reaction to injectable vitamin B12, which is rarely seen. This could be due to sensitization to the vitamin B12 molecule itself or an IgE mediated reaction. We concluded that anaphylactic reaction to vitamin B12 is a rare …

The Long Shadow Of Cerebral Localization, Saad Shafqat
The Long Shadow Of Cerebral Localization, Saad Shafqat
Section of Neurology
In 1995, during my first week as a neurology resident at Massachusetts General Hospital, I had the privilege of meeting the late Raymond Adams. He was an established octogenarian by then, but the years had made no difference to his air of professionalism and academic authority. His reputation was made in the 1950s and 1960s, when he developed Boston as a major centre of clinical neurology. Among other things, he is immortalized through a famous textbook that has appeared in multiple editions. Our meeting took place at a clinical conference in which I was required to present a case. He …

Department of Family Medicine
A 55 year-old housewife presented to the Family Medicine Clinic due to recurrent oral ulcers for a year. She also had generalized itching, weakness, anorexia and abdominal distension after meals. She had visited several practitioners including family physicians and sub-specialists but a diagnosis was not reached. She was diagnosed to have Lichen Planus and Hepatitis C at family practice clinic. Since a health care system does not properly exist, patients seek treatment from sub-specialists without first consulting a primary care practitioner. This report identifies a failure in health care system and it is also recommended that all patients should be …

Elevated Ex Vivo Monocyte Chemotactic Protein-1 (Ccl2) In Pulmonary As Compared With Extra-Pulmonary Tuberculosis, Zahra Hasan, Irfan Zaidi, Bushra Jamil, M Aslam Khan, Akber Kanji, Rabia Hussain
Department of Pathology and Laboratory Medicine
Background: Tuberculosis causes 3 million deaths annually. The most common site of tuberculosis is pulmonary however; extra-pulmonary forms of the disease also remain prevalent. Restriction of Mycobacterium tuberculosis depends on effective recruitment and subsequent activation of T lymphocytes, mononuclear and polymorphonuclear cells to the site of infection. Tumor necrosis factor (TNF)-α is essential for granuloma formation and is a potent activator of monocyte chemotactic protein (MCP-1, CCL2). CCL2 is essential for recruitment of monocytes and T cells and has been shown to play a role in protection against tuberculosis. Interleukin -8 (CXCL8) is a potent activator of neutrophils. Increased …

Department of Medicine
Background
Autonomic nervous system (ANS) dysfunction is present in up to one third of patients with tetanus. The prognostic value of ANS dysfunction is known in severe tetanus but its value is not well established in mild to moderate tetanus.
Methods
Medical records of all patients admitted with tetanus at two academic tertiary care centers in Karachi, Pakistan were reviewed. The demographic, clinical and laboratory data was recorded and analyzed. ANS dysfunction was defined as presence of labile or persistent hypertension or hypotension and sinus tachycardia, tachyarrythmia or bradycardia on EKG.
