Platelets And Leucocyte Counts In Pregnancy, Saadiya Aziz Karim, Javaid H. Rizvi, Iffat Rizwana, Mohammad Khurshid, Sadiqua N. Jafarey Jan 1992

Platelets And Leucocyte Counts In Pregnancy, Saadiya Aziz Karim, Javaid H. Rizvi, Iffat Rizwana, Mohammad Khurshid, Sadiqua N. Jafarey

Department of Obstetrics & Gynaecology

A study involving the obstetric clinic population of 3 major teaching hospitals of Karachi has been conducted to define changes in leucocyte and platelet counts as pregnancy progresses. 573 “normal” pregnant women - 183 in the first trimester, 195 in the second trimester and 194 in the third trimester were included in this analysis. We have found leucocytosis to be a feature of normal pregnancy; the change is subsequent to a progressive increase in granulocytes. Platelet counts were found to decrease slightly as pregnancy progresses

Role Of Thymectomy In Myasthenia Gravis, Sohaila Mohsin Ali, Aziz Sonawalla, Irfan Altafullah, Hizbullah Sheikh Jan 1992

Role Of Thymectomy In Myasthenia Gravis, Sohaila Mohsin Ali, Aziz Sonawalla, Irfan Altafullah, Hizbullah Sheikh

Section of Urology

Thirteen patients with myasthenia gravis underwent total thymectomy between January, 1988 and December, 1991. The duration of symptoms prior to surgery varied from 2 months to 20 years. In a follow-up ranging from 2 months to 4 years, 11 patients showed a significant improvement with either complete discontinuation of medication of a marked reduction in doses. One patient with a small benign thymoma showed some improvement but subsequently required stepping up of anticholinesterase medication and addition of steroids and immune suppressants; another patient with atrophic thymic tissue had complete remission after thymectomy but developed myasthenic symptoms six months later requiring …

Radiation Induced Tumor Lysis Syndrome In Patients With Leukemia, Imtiaz A. Malik, Paul Vellozo, Mohammad Khurshid, M. Ata Khan Jan 1992

Radiation Induced Tumor Lysis Syndrome In Patients With Leukemia, Imtiaz A. Malik, Paul Vellozo, Mohammad Khurshid, M. Ata Khan

Department of Medicine

Tumour lysis syndrome is a catastrophic complica­lion of treatment of certain neoplasms. It is usually seen with the tumours that have high growth fractions, increased bulk and extreme sensitivity to cytotoxic therapy. Most commonly it occurs in association with hematologic malignancies such as lymphomas and leukaemias. Rarely it has been observed with solid tumours like small cell lung cancer, seminoma and carcinoma of the breast. The syndrome develops due to massive cell lysis occurring within a few hours to a few days of starting the cytotoxic therapy. It is characterized by hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcaemia. Acute renal failure, cardiac …

Supervised Training Of Practical Procedures In The Internal Medicine Residency, Z Abbas, S Abid, J A. Khan, A Jabbar

Section of Gastroenterology

In order to get feedback whether the medical residents are getting adequate supervised training to perform practical procedures, a questionnaire was distributed among the residents asking their involvement in sixteen frequently performed procedures in the medical unit of the Aga Khan University Medical Centre. Though the residents were satisfied about their training in doing lumbar punctures, pleural and peritoneal aspirations, bone marrow aspiration and trephine and chest tubes placement, they showed their concern about training in putting central lines, venous cut downs, cardiac pacing and biopsies. A better schedule training programme, organized subspecialty rotation, continuous evaluation of resident's skill, credentialing …

Yet Another Cause Of Chronic Viral Hepatitis?, H A. Shah, S Abid, S Hamid, S W. Jafri, Z Abbas, T Qaseem, H Shaikh, A H. Khan

Section of Gastroenterology

The clinical features, course and histology of liver in 20 patients; mostly middle aged to elderly females, closely resembling chronic Non A Non B hepatitis is presented. They presented quite late in their disease and therefore, complications such as variceal bleeds, ascites and encephalopathy were frequent. Our patients were negative for hepatitis B and C virus serology. Metabolic and immune causes of chronic liver disease were also ruled out. To the best of our knowledge, this is the first study of its kind elaborating the clinical features, course and histology of liver in chronic Non B Non C hepatitis and …

Sertoli Cell Only Syndrome (Secos): Lessons From Case Studies, Jamsheer J Talati, Hizbullah Sheikh

Section of Urology

Between June 85 and December 87, 69 testicular biopsies were submitted for histopathological examination during investigation of infertility; ten (14%) patients had a Sertoli cell only syndrome. The history, clinical features, and hormonal profiles were analyzed in an attempt to categorize these patients on aetiological basis. Two followed treatment of malignancy--one by radiation for testicular cancer and one by cyclophosphamide for a lymphoma. One had unilateral cryptorchidism. Mumps was etiological factor in one patient. FSH levels determined in 6 patients were elevated in all suggesting a possible dependence of (sick) Sertoli cells on spermatogenic cells for production of inhibin. Alternative …

Transcutaneous Bilirubinometry In Pakistani Newborns: A Preliminary Report, Z A. Bhutta, K Yusuf Jul 1991

Transcutaneous Bilirubinometry In Pakistani Newborns: A Preliminary Report, Z A. Bhutta, K Yusuf

Department of Paediatrics and Child Health

Neonatal hyperbilirubinemia is a frequently encountered problem in the neonatal period and carries a potential risk of encephalopathy. Early detection and quantification is important, and transcutaneous bilirubinometry (TcB) has been recommended as a non-invasive method for rapid screening. We prospectively compared the efficacy of TcB in 65 normal Pakistani jaundiced newborns undergoing simultaneous serum bilirubin measurements. Although the correlation between the two methods was significant (r = 0.66, P less than 0.01), the scatter was wide and the specificity only 53%. Although the technique offers the potential for non-invasive early screening of neonatal hyperbilirubinemia, it requires further validation in a …

Heterogeneity Of Methotrexate Binding In Human Colon Tumor Cells, M P. Iqbal, N Mehboobali, M A. Waqar, M Ahmed

Department of Biological & Biomedical Sciences

[3H]-methotrexate binding at pH 5.0 and pH 7.2 by the cytosol of tumor tissues and the surrounding normal areas of the gastrointestinal tract of patients suffering from colon or gastric cancer has been used to identify in these cells the presence of a binder of methotrexate having low-affinity for this drug in addition to the enzyme dihydrofolate reductase. Scatchard analysis of the [3H]-methotrexate binding data by a colon tumor sample also reveals that there are two binders of this drug present in the cytosol of these cells. The association constant (Kass) for one binder of methotrexate is = 5.6 x …

Fulminant Hepatic Failure With Typhoid Fever In Childhood, Z A. Bhutta

Department of Paediatrics and Child Health

Although hepatic dysfunction has been described among adults with typhoid, there are few reports of significant hepatic functional impairment in children with typhoid. Of 355 children with culture proven typhoid seen at the Aga Khan University Hospital, hepatomegaly was noted in 118 (33%) and isolated right hypochondrial tenderness in 30 (8.5%). The liver function tests were normal in 78% and 47% of these children respectively and significant hepatic dysfunction was seen only in 26 (7.3%). However, children with typhoid and significant hepatic dysfunction had higher mortality (P less than 0.001) and two patients presented with a picture of fulminant hepatic …

Efficient Immortalization Of Luminal Epithelial Cells From Human Mammary Gland By Introduction Of Simian Virus 40 Large Tumor Antigen With A Recombinant Retrovirus, Bartek J, Bartkova J, Kyprianou N, El-Nasir Lalani, Staskova Z, Shearer M, Chang S, Taylor Papadimitriou J

Department of Pathology and Laboratory Medicine

When defined in terms of markers for normal cell lineages, most invasive breast cancer cells correspond to the phenotype of the common luminal epithelial cell found in the terminal ductal lobular units. Luminal epithelial cells cultured from milk, which have limited proliferative potential, have now been immortalized by introducing the gene encoding simian virus 40 large tumor (T) antigen. Infection with a recombinant retrovirus proved to be 50-100 times more efficient than calcium phosphate transfection, and of the 17 cell lines isolated, only 5 passed through a crisis period as characterized by cessation of growth. When characterized by immunohistochemical staining …

The Effects Of Suxamethonium And Pancuronium On The Haemodynamic Response To Endotracheal Intubation, F A. Khan, R S. Kamal

Department of Anaesthesia

The pharmacological effects of suxamethonium and pancuronium on the cardiovascular system may vary and therefore alter the haemodynamic response to intubation. The arterial blood pressure, the heart rate and the rate pressure product were measured as parameters of haemodynamic change in forty adult ASA. I and II patients undergoing laryngoscopy and endotracheal intubation in a randomised controlled study. The patients were induced with either thiopentone/suxamethonium (Group A) or thiopentone/pancuronium (Group B). There was no significant difference between the groups on comparison of systolic and diastolic blood pressure changes. Pancuronium, however, caused a significantly higher rise in the heart rate after …
