Fatal Transfusion Related Acute Lung Injury Following Coronary Artery By-Pass Surgery: A Case Report., Fauzia Ahmad Bawany, Hasanat Sharif

Section of Cardiothoracic Surgery

Background:Transfusion related acute lung injury (TRALI) is a potentially fatal Acute Lung Injury following transfusion of blood components. Hypotheses implicate donor-derived anti-human leukocyte antigen or granulocyte antibodies reacting with recipients' leukocytes, releasing inflammatory mediators. Lack of agreement on underlying cellular and molecular mechanisms renders improving transfusion safety difficult and expensive.

Case Presentation:

Literature search has not revealed any case of TRALI from Pakistan. We report the case of fatal TRALI in a 68 year old male who received blood products after coronary artery by-pass surgery.

Conclusion:

This article aims to create awareness about this complication and suggests that post …

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

Section of Urology

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 …

Use Of Anticonvulsants Drugs For Neuropathic Painful Conditions, Aziza Mohammad Hussain, Gauhar Afshan

Department of Anaesthesia

Neuropathic pain, a form of chronic pain initiated and sustained by an insult to the peripheral or central nervous system, is a challenge to clinicians as it does not respond well to traditional pain therapies. However exact pathophysiology is not known but considering similarities between epilepsy models and in neuropathic pain models justify the rationale for use of anticonvulsant drugs in the symptomatic management of neuropathic pain disorders. The role of anticonvulsant drugs in the treatment of neuropathic pain is evolving and various clinical trials have used these anticonvulsants and shown positive results in the treatment of trigeminal neuralgia, painful …

Surgical Management Of Blunt Pancreatic Trauma: A Modus Operandi Or Individualized Therapy?, Muhammad Rizwan Khan, Kiran Ejaz

Section of General Surgery

The overall rate of blunt pancreatic trauma observed in level one trauma centers is rather low compared to other injuries, with a reported prevalence of 0.4 per 100,000 hospital admissions. The situation may be further complicated by the presence of associated major visceral injuries in these patients. A number of previous reports indicate that blunt pancreatic trauma carries high morbidity and mortality rates, especially when diagnosis is delayed or inappropriate surgery is attempted. Many mandate prompt surgical explorations for organ-specific diagnosis on CT; however other literature and upcoming studies prove otherwise. Over the years, several technologic advances have increased the …

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

Section of Urology

BACKGROUND:

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 …

Migraine And Patent Foramen Ovale: Exploring The Association And A Possible Treatment Option, Muhammed Yaser Hasan

Department of Biological & Biomedical Sciences

Migraine is a very common type of headache. With a prevalence of 10-12%, migraine ranks 19th among diseases causing worldwide morbidity. Number of studies have shown a high prevalence of patent foramen ovale (PFO) in patients with migraine, especially migraine with aura. The right to left shunting of blood in a PFO could serve as a conduit for chemicals that would exert a trigger effect on hyper excitable neurons leading to the development of migraine. Furthermore patients with PFO and migraine also show a marked improvement in their symptoms after percutaneous closure of the PFO. This review is a close …
