Role Of Surgery In Locally Advanced Prostate Cancer, 2016 Aga Khan University
Role Of Surgery In Locally Advanced Prostate Cancer, Nazim Syed Muhammad, Farhat Abbas
A significant proportion of patients present with locally advanced prostate cancer with inherent higher risk of local recurrence and systemic relapse after initial treatment. Recent literature favors combination of radiation therapy and extended hormonal therapy for this subset of patients. The effectiveness of Radical prostatectomy (RP) alone for locally advanced prostate cancer is controversial and is a focus of debate. However, it can decrease the tumor burden and allows the accurate and precise pathological staging with the need for subsequent treatment. Comparison of RP and other treatment modalities is difficult and incorrect because of inherent selection bias. RP as a ...
Surgical Management Of Penile Cancer--Report Of Two Cases., 2016 Aga Khan University
Surgical Management Of Penile Cancer--Report Of Two Cases., M Amjad Noor, Hammad Ather, M Nasir Sulaiman, Farhat Abbas
Penile carcinoma (PC) is a rare tumor, accounting for 0.4-0.6% of all male malignancies. There are remarkable racial and geographic differences in the prevalence of penile cancer. In United States, 1% of all male cancers are penile malignancies, with annual incidence of 1-2 new cases per 100,000 men. In certain areas of South America, Asia and Africa the frequency is as high as 10-20% of all male cancers. Many areas in Asia however, have very low figures; in Taiwan for example it comprised only 0.25% of all male cancers1. Penile carcinoma is most frequent ...
Surgical Management Of Pheochromocytoma In A 13-Week Pregnant Woman., 2016 Aga Khan University
Surgical Management Of Pheochromocytoma In A 13-Week Pregnant Woman., Mazhar Ali Memon, Wajahat Aziz, Farhat Abbas
A 34-year-old 13-week pregnant woman presented with hypertension refractory to medical therapy and on workup was found to have a right adrenal mass. Due to her persistent increased blood pressure she was advised urinary vanillylmandelic acid (VMA) and its level was raised. MRI of the abdomen showed a well-circumcised lesion in the right adrenal of 3.0×2.5 cm suggestive of pheochromocytoma. The patient was started on antihypertensives including α-blockers and β-blockers and planned for right open adrenalectomy. Intraoperatively, blood pressure was raised up to 180/110 mm Hg on slight manipulation of adrenal gland which was controlled with ...
Silencing Of Mbd1 And Mecp2 In Prostate-Cancer-Derived Pc3 Cells Produces Differential Gene Expression Profiles And Cellular Phenotypes., Yaqinuddin Ahmed, Farhat Abbas, Syed S. Naqvi, Mohammad U. Bashir, Romena Qazi, Sohail A. Qureshi
Alterations in genomic CpG methylation patterns have been found to be associated with cell transformation and neoplasia. Although it is recognized that methylation of CpG residues negatively regulates gene expression, how the various MBPs (methyl-binding proteins) contribute to this process remains elusive. To determine whether the two well characterized proteins MeCP2 (methyl-CpG-binding protein 2) and MBD1 (methyl-CpG-binding domain 1) have distinct or redundant functions, we employed RNAi (RNA interference) to silence their expression in the prostate cancer-derived PC3cell line, and subsequently compared cell growth, invasion and migration properties of these cell lines in addition to their respective mRNA-expressionprofiles. Cells devoid ...

Renal Arteriovenous Malformation: An Unusual Cause Of Recurrent Haematuria., 2016 Aga Khan University
Renal Arteriovenous Malformation: An Unusual Cause Of Recurrent Haematuria., Mazhar Ali, Wajahat Aziz, Farhat Abbas
A 54-year-old woman presented with gross painless haematuria. Initial workup showed no abnormality except mild hydronephrosis on CT scan. Cystoscopy and retrograde pyelography did not find any gross lesion and her urine cytology was also negative. She had recurrent haematuria so her CT was reviewed with the radiologist with clinical suspicion of arteriovenous malformation (AVM) which was suggested by relatively increased contrast density in the hemiazygous vein and renal vein in the arterial phase. She underwent angioembiolisation of left renal AVM after which her haematuria settled.
Post-Chemotherapy Residual Mass In Stage Iic Seminomatous Testicular Tumor, 2016 Aga Khan University
Post-Chemotherapy Residual Mass In Stage Iic Seminomatous Testicular Tumor, N A. Ahmad, S R. Biyabani, Farhat Abbas
The management of patients with residual masses following chemotherapy for advanced seminoma remains a difficult problem with no clear guidelines. While most patients with advanced seminoma achieve a complete or partial response with cisplatin based chemotherapy1, a significant number will reveal a residual mass on follow up CT scan or MR imaging2,3. Management options for post chemotherapy residual mass in a case of seminoma include close observation, radiation therapy and excisional surgery. While 80 to 85% of residual masses represent either fibrosis or necrotic tissue needing no further therapy, 10 to 15% may contain viable tumor ...

Mediastinal Parathyroid Adenoma Causing Primary Hyperparathyroidism., 2016 Aga Khan University
Mediastinal Parathyroid Adenoma Causing Primary Hyperparathyroidism., Farhat Abbas, Syed Raziuddin Biyabani, Amanullah Memon, Jamsheer Talati
An ectopically placed parathyroid adenoma in the anterior mediastinum is a rare cause of persistent or recurrent primary hyperparathyroidism (PHPT) and is recognized as an important cause of failed primary neck exploration. We encountered 3 such cases amongst 70 surgically treated patients with PHPT (4.3%) over a 20-year period. In 2 cases, the offending adenoma could be removed at first exploration whereas in the 3rd case, it was successfully removed with mediastinal exploration after 2 failed neck explorations. In established cases of PHPT with equivocal preoperative localization studies or negative neck explorations, an ectopically placed parathyroid adenoma should ...

Down-Regulation Of Dnmt3b In Pc3 Cells Effects Locus-Specific Dna Methylation, And Represses Cellular Growth And Migration., Ahmed Yaqinuddin, Sohail A. Qureshi, Romena Qazi, Farhat Abbas
Aberrations in DNA methylation patterns promote changes in gene expression patterns and are invariably associated with neoplasia. DNA methylation is carried out and maintained by several DNA methyltransferases (DNMTs) among which DNMT1 functions as a maintenance methylase while DNMT3a and 3b serve as de novo enzymes. Although DNMT3b has been shown to preferentially target the methylationof DNA sequences residing in pericentric heterochromatin whether it is involved in gene specific methylation remains an open question. To address this issue, we have silenced the expression of DNMT3b in the prostate-derived PC3 cells through RNA interference and subsequently studied the accompanied cellular ...
Correlation Of Three Immunohistochemically Detected Markers Of Neuroendocrine Differentiation With Clinical Predictors Of Disease Progression In Prostate Cancer., M Hammad Ather, Farhat Abbas, Nuzhat Fauqui, Mohammad Israr, Shahid Pervez
Background: The importance of immuno-histological detection of neuroendocrine differentiation in prostatic adenocarcinoma with respect to disease at presentation and Gleason grade is gaining acceptance. There is limited literature on the relative significance of three commonly used markers of NE differentiation i.e. Chromogranin A (CgA), Neuron specific enolase (NSE) and Synaptophysin (Syn). In the current work we have assessed the correlation of immuno-histological detection of neuroendocrine differentiation in prostatic adenocarcinoma with respect to disease at presentation and Gleason grade and to determine the relative value of various markers. Materials and methods: Consecutive samples of malignant prostatic specimens (Transurethral resection of ...

An Unusual Combination Of Extra-Adrenal Pheochromocytoma And Arteriovenous Malformation Of The Ureter In A Young Adult., Ali Khawaja, Wajahat Aziz, Syed Muhammad Nazim, Farhat Abbas
We present a case of a 24-year-old gentleman who presented with painless pan haematuria for 2 weeks. During the workup, he was diagnosed to have a retrocaval mass after a CT scan while cystoscopy revealed a polypoidal pulsating lesion in the left ureter. After surgical manipulation of the retrocaval mass, the blood pressure of the patient raised to 260/130 mm Hg. It was completely resected and diagnosed as extra-adrenalpheochromocytoma (paraganglioma) after histopathology. The lesion in the ureter was completely excised and fulgurated and diagnosed as anarteriovenous malformation. To the best of our knowledge, this is the first patient to ...
