Sertoli Cell Only Syndrome (Secos): Lessons From Case Studies, Jamsheer J Talati, Hizbullah Sheikh Sep 1991

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 Jun 1991

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 Mar 1991

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 …

Extracorporeal Shock Wave Lithotripsy, Jamsheer J Talati Jan 1990

Extracorporeal Shock Wave Lithotripsy, Jamsheer J Talati

Section of Urology

After circumcision the first operations done on man were for bladder stone. Done by charlatans the operation often resulted in loss of life and caused the early lithotomists to maintain a peri­patetic existence, vanishing from the town the night after surgery was performed. About two centuries ago stones became a common disease amongst kings: surgeons took over from the charlatans and commenced blind skilful mechanical lithotripsy where a curved instrument was introduced per urethram, its jaws opened to engage the stone which was then crushed by a mechanical (screw driven) closure of the jaws. Now-a-days urinary bladder lithotripsy is done …

Neonatal Screening For Congenital Hypothyroidism In Pakistan, Murntaz Lakhani, Mohammad Khurshid, Shehla H. Naqvi, Mohammad Akber Jan 1989

Neonatal Screening For Congenital Hypothyroidism In Pakistan, Murntaz Lakhani, Mohammad Khurshid, Shehla H. Naqvi, Mohammad Akber

Department of Paediatrics and Child Health

Congenital hypothyroidism is a preventable cause of mental retardation. Since clinical signs of congenital hypothyroidism do not generally become obvious before three months of age, screening programmes have been introduced in North America and Europe, which consist of T4 or TSH screening on newborn infants on the third day of life. The screening for congenital hypothyroidism was initiated in Pakistan by the Aga Khan University Hospital (AKUH) in March 1987. By April 1988, 5000 neonates were screened and five cases of congenital hypothyroidism were diagnosed. The study revealed the incidence of hypothyroidism to be one case per 1000 newborns which …
