Nipple Aspirate Cytology And Pathologic Parameters Predict Residual Cancer And Nodal Involvement After Excisional Breast Biopsy., E R Sauter, H Ehya, A Mammen, G Klein

Department of Surgery Faculty Papers

We previously demonstrated that abnormal nipple aspirate fluid (NAF) cytology predicted residual breast cancer (RC) and tumour size after excisional biopsy (EB), although normal NAF cytology did not exclude RC. Tumour size correlates with the risk of lymph node (LN) metastases. LN metastases provide prognostic information allowing medical and radiation oncologists to determine the need for adjuvant therapy. We hypothesized that pathologic factors known after EB, combined with NAF cytology, would predict with a high degree of accuracy the presence of RC and LN spread. NAF cytology and pathologic parameters: tumour distance from biopsy margins, multifocal and multicentric disease, sub-type …

Prevalence Of Smokers Among Air-Conditioned Coaches, Pakistan, R Mal, N Rizvi, S Rathi

Section of Otolaryngology, Head & Neck Surgery

Objective: To estimate the proportion of smokers among passengers of air-conditioned (A/C) coaches running between Karachi and Hyderabad. Pakistan.METHOD: A cross-sectional survey was done on passengers and staff members of 20 air-conditioned coaches.Results: Of 847 passengers interviewed, 17.3% were smokers and 11.7% passengers smoked during travel while rest of them remained passive smokers. Out of 147 smokers 91.2% were literate persons. Among staff members 59.3% were smokers. Approximately 56% of smokers among passengers were in the age range of 14-40 years. In 95% of A/C coaches there were no anti-smoking warning signs or written words present.CONCLUSION: In this study majority …

Continuous Quality Assessment; Development Of A Simple Computer Based Model For Audit, N K. Waheed, F S. Awan, A Ahad, A Rahman, K M. Pal

Department of Surgery Docs

Objective: Accurate assessment of quality of care is a fundamental first step in the process of quality improvement. The vast amount of data generated in a hospital mandates some form of computerization for management of information. We describe a locally developed simple computer based program to access relevant information from a hospital patient management network. The objective was to reduce the amount of manual work involved for busy clinicians attempting to audit quality of care.Methods: A single surgical procedure, Laparoscopic Cholecystectomy was chosen. Quality indicators were identified by literature review as conversion rate from laparoscopic to open cholecystectomy and length …

Neoplastic Growth Of Cerebral Cavernous Malformation Presenting With Impending Cerebral Herniation: A Case Report And Review Of The Literature On De Novo Growth Of Cavernomas, Arshad A. Siddiqui, Rashid Jooma

Section of Neurosurgery

Background: Cerebral cavernomas are rare vascular anomalies and their expansile growth has been considered to be mainly due to recurrent hemorrhages. They are not generally reported to show aggressive behavior.
Case description: A 27-year-old male presented with headache, visual disturbances, and a 17-year history of seizures. He was known to have a temporal lobe lesion on CT scan, consistent with a diagnosis of cavernous malformation but with no relevant family history. Serial clinical and radiological follow-up revealed a progressive increase in the size of the lesion with formation of a growing cyst of 7 cm in diameter, which produced mass …

An Audit Of Blood Cross-Match Ordering Practices At The Aga Khan University Hospital: First Step Towards A Maximum Surgical Blood Ordering Schedule, T Chawla, G N. Kakepoto, M A. Khan

Department of Surgery Docs

Objective: In the absence of an explicit maximum blood order policy, ordering for blood transfusion is frequently based on subjective anticipation of blood loss instead of evidence based estimates of average requirement in a particular procedure. This study was done to assess current practice and the feasibility of a prospective randomized work to develop practice guidelines.METHOD: We audited transfusion data for elective surgical procedures in our hospital during the last 2 years. Cross-matched to transfused ratio (C/T ratio) and Transfusion Index (Ti) for each of the elective surgical procedures was performed during the study period. C/T ratio is used as …

Association Of Viral Genome With Graft Loss In Children After Cardiac Transplantation., Girish S. Shirali, J Ni, R E. Chinnock, J K. Johnston, G L. Rosenthal, N E. Bowles, J A. Towbin

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The survival of recipients of cardiac allografts is limited by rejection, lymphoproliferative disease, and coronary vasculopathy. The purpose of this study in children who had received heart transplants was to evaluate the cardiac allografts for myocardial viral infections and to determine whether the presence of viral genome in the myocardium correlates with rejection, coronary vasculopathy, or graft loss.

METHODS: We enrolled heart-transplant recipients 1 day to 18 years old who were undergoing evaluation for possible rejection and coronary vasculopathy. Endomyocardial-biopsy specimens were evaluated for evidence of rejection with the use of standard criteria and were analyzed for the presence …

Diagnostic Issues In Abdominal Tuberculosis, M R. Khan, I R. Khan, K M. Pal

Department of Surgery Docs

Objective: To analyze the modes of presentation and diagnostic issues in the management of abdominal tuberculosis at a tertiary care hospital in a developing country, where most of the established diagnostic modalities are available.SETTING: The Aga Khan University Hospital, Karachi.Methods: This study is a retrospective review of medical records of all inpatients, diagnosed to have abdominal tuberculosis, from January 1991 to December 1997. The data was collected and particularly analyzed for spectrum of presentation and role of various diagnostic modalities. Of special interest was the sub-group of patients, who after all investigations did not have a firm diagnosis. Following a …

Vestibular Schwannomas: Clinical Presentation, Management And Outcome, M S. Awan, H U. Qureshi, A A. Sheikh, M M. Ali

Section of Neurosurgery

Objective: To review the demographic trends clinical spectrum, diagnosis, management and outcome of patients with vestibular Schwannoma and to identify areas where improvements are needed.
Methods: All patients with vestibular schwannoma admitted to the Aga Khan University Hospital over the past 11 years were reviewed retrospectively.

Other clinical features included cranial nerve palsies (59%) and headache (55%). Fifty percent had signs of raised intracranial pressure. Neuroimaging revealed "Stage IV b" (tumor distorting the brainstem and compressing the …

Is Extended Volume Of External Beam Irradiation Beneficial In Post-Esophagectomy High Risk Patients Receiving Combined Chemoradiation Therapy?, E. Yu, A. R. Dar, R. Ash, G. Videtic, P. Truong, L. Stitt, A. Tomiak, M. Vincent, R. Malthaner, I. Craig, E. Brecevic, W. Kocha, R. Inculet, M. Lefcoe

OBJECTIVE: To assess the value of extended volume irradiation with anastomotic coverage in high risk resected esophageal cancer patients.

METHOD: A retrospective study was undertaken at LRCC from 1989-1999 for high risk resected esophageal cancer patients. Adjuvant treatments consisted of 4 cycles of chemotherapy (epirubicin/fluorouracil/cisplatin or cisplatin/fluorouracil), and local regional irradiation with or without coverage of the anastomotic site. Radiation dose ranged from 45-60Gy at 1.8-2.0 Gy/fraction given with initial anterior-posterior/posterior-anterior arrangement with either extended (with anastomotic coverage) or small (without anastomotic coverage) field followed by oblique fields for boost.

RESULT: One hundred eighty-eight charts were reviewed. Seventy-two patients were …
