Edward Yu

PURPOSE: In this pilot study of high-dose-rate brachytherapy to the lumpectomy site as the sole radiation, ipsilateral and contralateral breast recurrences are documented with specific attention to the location of recurrence relative to the lumpectomy site. METHODS: Between March 1992 and January 1996, 39 patients with T1 (32 patients) and T2 breast cancers received 37.2 Gy in 10 fractions (b.i.d.) over 1 week prescribed to a volume encompassing the surgical clips. Thirteen received adjuvant tamoxifen, and 4 received chemotherapy. Follow-up included annual bilateral mammograms and clinical breast examination every 3 to 6 months. Whereas 13 patients had intraoperative implantation of …

Septic Arthritis Of The Hip In Children: Aga Khan University Hospital Experience In Pakistan, Muhammad Umer, Pervaiz Hashmi, Tashfeen Ahmad, M Ahmed, Masood Umer

Section of Orthopaedic Surgery

Objective: To present clinical, radiological and bacteriological features and short term outcome of septic arthritis of the hip in children.
Methods: There were 23 male and 16 female children, including 6 neonates and 10 infants with a mean age of 3.9 years. Diagnosis of septic hip was made on clinical grounds, supplemented by X-rays, leukocyte count and the erythrocyte sedimentation rate (ESR). Thirty nine patients with 40 hips were followed for a mean time period of 76 weeks. All patients had a positive joint aspirate (pus) and underwent surgical decompression along with intravenous antibiotic therapy.
Results: Symptoms of pain, fever …

Peritumoral Cystic Meningioma, Arshad A. Siddiqui, Junaid Asharaf, Ahmed Ali Shah

Section of Neurosurgery

A case of 39 years old male is described who presented with headache, right-sided focal fits and decreased power in the right hand. CT scan brain showed a left fronto-parietal cystic lesion with centrolateral intramural nodule with homogenous enhancement. At surgery, the extra-axial lesion with cyst containing xanthochromic fluid had a well-defined capsule that could easily be separated from the peri-lesional cortical surface. The dural-based nodule with its cyst wall was resected in toto. The histopathology of mural nodule was reported as meningioma while the cyst wall histology revealed meningothelial cells.

Experience In 118 Consecutive Patients Undergoing Ct-Guided Stereotactic Surgery Utilizing The Cosman-Robert-Wells (Crw) Frame, G. R. Sharma, H. Siddiqui, Rashid Jooma

Section of Neurosurgery

Aims: To evaluate the efficacy of CT-guided neurosurgical procedures done on patients operated by this modality.
Methods: Between January 1997 and March 2000, 118 patients undergoing CT-guided stereotactic procedures were recruited to the study. The CRW III stereotactic system (Radionics, USA) and the TSX-00ZA CT Scanner (Toshiba, Japan) were used for all the procedures in the series. These procedures were directed to symptomatic brain lesions or for the treatment of Parkinsonian tremor.
Results: Of 118 patients, 109 had intra-cranial lesions and 9 had Parkinson's Disease. The stereotactic procedures performed on these patients were: biopsies in 62, guided mini-craniotomies in 22, …

Radiosurgery For The Control Of Glomus Jugulare Tumours, Muhammad Ehsan Bari, A A. Kemeny, D M C Forster, M W. Radatz

Section of Neurosurgery

Objective: To ascertain the efficacy of stereotactic radiosurgery (gamma knife) for the control of glomus jugulare tumours.
Method: Between March 1994 and December 1997 we treated eight patients of glomus jugulare tumour with radiosurgery. These patients have been followed for more than four years (range 52 to 97 months). The age of the patients ranged between 32-64 years (mean 53 years). The male: female ratio was 3:5. Three patients had previously undergone surgery and one had unsuccessful embolization. The dose applied to tumour margin ranged between 16-25 Gy (median 25 Gy). Patients were followed up with yearly MRI scans and …

Effects Of Tacrolimus On Ischemia-Reperfusion Injury., Shawn D. St Peter, Adyr A. Moss, David C. Mulligan

Manuscripts, Articles, Book Chapters and Other Papers

In addition to efficacious immunosuppression for the benefit of organ transplantation, tacrolimus has diverse actions that result in amelioration of ischemia-reperfusion injury. Knowledge is accumulating rapidly on the mechanisms through which tacrolimus exerts these cytoprotective effects, including alterations in microcirculation, free radical metabolism, calcium-activated pathways, inflammatory cascades, mitochondrial stability, apoptosis, stress-response proteins, and tissue recovery. Within the nucleus, actions mediating the effects of tacrolimus appear to be dominantly influenced by interactions with the transcription factor, nuclear factor-kappaB. Because tacrolimus is a cornerstone agent in immunosuppression regimens throughout the world and knowledge of its cellular mechanisms is evolving, it is important …

Tacrolimus As A Liver Flush Solution To Ameliorate The Effects Of Ischemia/Reperfusion Injury Following Liver Transplantation., Shawn D. St Peter, David J. Post, Manuel I. Rodriguez-Davalos, David D. Douglas, Adyr A. Moss, David C. Mulligan

Manuscripts, Articles, Book Chapters and Other Papers

The goal of this report is to evaluate in a prospective randomized fashion the effect of flushing hepatic allografts with tacrolimus before transplantation. A prospective, double-blinded, randomized trial was performed. Twenty patients receiving orthotopic liver transplants from October 2000 to October 2001 were randomized into two groups. Group 1 (active) was administered tacrolimus, 20 ng/mL, plus Plasma-lyte A (Baxter Healthcare Corp, Deerfield, IL) liver flush solution; and group 2 (placebo) was administered only Plasma-lyte A. Ischemia/reperfusion injury was assessed in both groups after transplantation by means of serum laboratory values to assess hepatocellular damage, synthetic function, and ion transport capacity. …

Optimization Of Low Pre-Operative Hemoglobin Reduces Transfusion Requirement In Patients Undergoing Transurethral Resection Of Prostate, Hammad Ather, Nuzhat Faruqui, F. Abid

Section of Urology

Objective: To identify factors that influence peri-operative hemorrhage in view of reducing the need for transfusions in patients undergoing trans uretheral resection of prostate (TURP).
Methods: All patients undergoing TURP between January 1997 and December 1999 were identified using lCD 9CM coding and indexing system. Overall 430 patients were identified, however, 384 charts were included and reviewed for demographics, pre and intra-operative data and post-operative morbidity. Patients were divided into two groups on the basis of presence of significant hemorrhage.
Results: Overall 384 patients were analyzed. Nineteen patients had hemorrhage - group I whereas 365had no significant hemorrhage …

The Prevalence Of Silent Kidney Stones: An Ultrasonographic Screening Study, Buchholz Niels-Peter, Farhat Abbas, R Khan, Jamsheer J. Talati, M Afzal, I Rizvi

Section of Urology

Objective: Silent and not yet discovered stones of the upper urinary tract are potentially dangerous, since in due course they may cause infection, obstruction and renal damage. The aim of this study was to determine the prevalence of such silent kidney stones in a representative Pakistani population of Karachi.
Subjects and Methods: We studied 201 consecutive subjects at our hospital who underwent additional kidney screening whilst undergoing abdominal ultrasound. All these subjects did not have a history or symptoms of urolithiasis.
Results: We found silent kidney stones in 3% of subjects. All stone bearers were males. Most stones were in …
