Acute caecal volvulus: A diagnostic paradigm.

Acute Caecal Volvulus is a rare etiology in cases of Intestinal obstruction. We are presenting the data of 11 cases out of 1032 cases of intestinal obstruction between June 2008 to June 2013, who presented in the emergency department of Bahawal Victoria Hospital Bahawalpur. The mean age was 36±3.

Properties of virion transactivator proteins encoded by primate cytomegaloviruses.

Background: Human cytomegalovirus (HCMV) is a betaherpesvirus that causes severe disease in situations where the immune system is immature or compromised. HCMV immediate early (IE) gene expression is stimulated by the virion phosphoprotein pp71, encoded by open reading frame (ORF) UL82, and this transactivation activity is important for the efficient initiation of viral replication. It is currently recognized that pp71 acts to overcome cellular intrinsic defences that otherwise block viral IE gene expression, and that interactions of pp71 with the cell proteins Daxx and ATRX are important for this function.

Renal artery stenosis in renal transplantation presentation and management.

A review of the angioplasty records between 1990 and 1995 at the King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia revealed ten cases of transplant renal artery stenosis (RAS). The diagnosis in these cases was confirmed by renal angiography and all were treated by angioplasty. All study patients presented with uncontrolled hypertension in spite of multiple medications; eight had renal functional impairment and two patients had recurrent unexplained pulmonary edema in addition.

Timing isn't everything: an analysis of when to start salvage chemotherapy in ovarian cancer.

Objective: Results from GOG 178 showed a prolongation of progression-free survival (PFS) with the immediate use of chemotherapy (CT) following a complete clinical response (CR) in patients with stage III-IV ovarian cancer. We wanted to evaluate our strategy of reserving second line (2nd line) chemotherapy to the time of clinical recurrence by determining PFS intervals following first, second, and third line agents and to compare these finding to results of GOG 178.

Methods: We conducted a retrospective parallel study to GOG 178 using identical criteria for PFS definitions.
