Intraoperative catheter directed thrombolytic therapy for the treatment of superior mesenteric and portal Vein thrombosis.

INTRODUCTION AND CASE PRESENTATION: Acute portal and superior mesenteric vein thrombosis(SMV) is a rare but potentially lethal condition that is often characterized by generalized and non-specific symptoms. A high index of suspicion is warranted for early diagnosis and management. We present a case of 54 year old male who presented with generalized abdominal pain which was later accompanied by hemodynamic instability and radiological diagnosis of portal vein and superior mesenteric vein thrombosis. DISCUSSION: The management of SMV can be divided into medical and surgical therapy. Patients who have clear signs of peritonitis will require emergent surgery. Interventions for life-threatening portal vein thrombosis are limited and poorly described in the literature. CONCLUSION: We report a case of extensive portal vein thrombosis(PVT) advancing proximally to involve the superior mesenteric vein. Rapid portal vein patency and improved hepatic function was achieved with the direct use of tissue plasminogen activator infusion via operatively placed middle colic vein catheter.

Caecal diverticulitis: a rare cause of right iliac fossa pain.

We present a case of a young boy with an unusual cause of right iliac fossa pain. His history, examination and laboratory investigations suggested a diagnosis of acute appendicitis. However preoperative abdominal CT revealed an inflamed solitary caecal diverticulum and a normal appendix. He was subsequently treated conservatively and recovered well, saving him from undergoing a general anaesthetic and abdominal surgery.

In vitro and in vivo anticancer effects of mevalonate pathway modulation on human cancer cells.

BACKGROUND: The increasing usage of statins (the 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors) has revealed a number of unexpected beneficial effects, including a reduction in cancer risk. METHODS: We investigated the direct anticancer effects of different statins approved for clinical use on human breast and brain cancer cells. We also explored the effects of statins on cancer cells using in silico simulations. RESULTS: In vitro studies showed that cerivastatin, pitavastatin, and fluvastatin were the most potent anti-proliferative, autophagy inducing agents in human cancer cells including stem cell-like primary glioblastoma cell lines. Consistently, pitavastatin was more effective than fluvastatin in inhibiting U87 tumour growth in vivo. Intraperitoneal injection was much better than oral administration in delaying glioblastoma growth. Following statin treatment, tumour cells were rescued by adding mevalonate and geranylgeranyl pyrophosphate. Knockdown of geranylgeranyl pyrophosphate synthetase-1 also induced strong cell autophagy and cell death in vitro and reduced U87 tumour growth in vivo. These data demonstrate that statins main effect is via targeting the mevalonate synthesis pathway in tumour cells. CONCLUSIONS: Our study demonstrates the potent anticancer effects of statins. These safe and well-tolerated drugs need to be further investigated as cancer chemotherapeutics in comprehensive clinical studies.

Cadaveric renal transplantation: a single-center experience.

INTRODUCTION: Renal transplantation remains the treatment of choice for end-stage renal disease (ESRD) in regard to patient survival. Iran was one of the first countries in the Middle East that began renal transplantation. METHODS: In a follow-up study, we enrolled all of our cadaveric renal transplant recipients from 2001 to 2007, namely, 39 cases. Related variables collected through checklists were entered into SPSS software version 16 and analyzed using the Kaplan-Meier method and by descriptive statistics. RESULTS: The mean age of the recipients was 35.18 +/- 14.27 years. Twenty-one patients (53.8%) were men. The underlying disease for development of ESRD was diabetes (7 cases, 21.2%), hypertension (24.2%), glomerulopathies (36.4%), polycystic disease (PKD; 2.6%), and 5 (15.2%) were unknown. Four recipients (10.3%) were hospitalized again because of acute tubular necrosis after transplantation. An acute rejection episode was diagnosed in 7 (17.9%) graft recipients. Surgical complications after transplantation were as follows: urinoma, lymphocele, and surgical site leakage (each 1 case). One-year patient survival rate was 89.7% in this study; 4 recipients died within 1-9 months after transplantation. Death-censored 1-year graft survival rate was 100%. DISCUSSION: The survival rate of cadaveric transplant was in an acceptable range.
