Intraperitoneal Haemorrhage Secondary to Rupture of Right Colic Artery Pseudoaneurysm: A Case Report and Literature Review.

This article presents the case of a 58-year-old woman who presented feeling unwell with pain in the right upper abdomen for three days. She had a history of splenic infarcts, was on lifelong warfarin and had recently returned from a trip to Gambia. She was admitted to the hospital under suspicion of sepsis of unknown origin, and a CT scan later revealed haemoperitoneum along with a pseudoaneurysm of the right colic artery.

Mirizzi's syndrome: A scoring system for preoperative diagnosis.

Background/aim: Mirizzi's syndrome (MS) is an unusual complication of gallstone disease and occurs in approximately 1% of patients with cholelithiasis. Majority of cases are not identified preoperatively, despite the availability of modern imaging techniques. A preoperative diagnosis can forewarn the operating surgeon and avoid bile duct injuries in cases of complicated cholecystitis.

Malrotation of Small Bowel-Diagnostic Computed Tomography (CT) Signs and Intraoperative Findings.

Right paraduodenal hernia usually occurs in setting of nonrotated small bowel, when small bowel herniates through Waldeyer's fossa (a defect in the first part of jejunal mesentery). It lies behind the superior mesenteric artery and inferior to the transverse colon or third portion of duodenum. We studied two cases of right paraduodenal hernia, an incomplete rotation, and nonrotation of small bowel, respectively, and describe CT abdomen signs, which can give a preoperative diagnosis.

Evidence Based Surgery: How Difficult is the Implication in Routine Practice?

Surgery as a discipline has perhaps been slower than other specialties to embrace evidence based principles. Today, surgeons all over Asia are prepared to challenge the dogma of yesterday. Surgical science which rests on a strong foundation of laboratory and clinical research can now be broadened to include the armamentarium of evidence based practice to advance surgical knowledge.

Enterolithiasis complicating eosinophilic enteritis: A case report and review of literature.

We report a case of eosinophilic enteritis involving the proximal small bowel, a relatively rare entity, presenting unusually as enteroliths in a 68-year-old man with complaints of anemia, malena and abdominal pain. The disease if diagnosed in the initial stages responds well to medical treatment but if associated with complications or misdiagnosed, surgical modality is the treatment of choice. In our case, the patient presented with enteroliths and strictures.

Ni(2+) selective sensors based on meso-tetrakis-{4-[tris-(4-allyl dimethylsilyl-phenyl)-silyl]-phenyl}porphyrin and (sal)(2)trien in poly(vinyl chloride) matrix.

PVC-based membranes of meso-tetrakis-{4-[tris-(4-allyl dimethylsilyl-phenyl)-silyl]-phenyl}porphyrin (I) and (sal)(2)trien (II) as electroactive material with dioctylphthalate (DOP), tri-n-butylphosphate (TBP), chloronapthalene (CN), dibutylphthalate (DBP) and dibutyl(butyl) phosphonate (DBBP) as plasticising solvent mediators have been found to act as Ni(2+) selective sensor. The best performance was obtained with the sensor having a membrane of composition of I: sodium tetraphenyl borate: PVC in the ratio 5:5:150. The sensor exhibits Nernstian response in the activity range 2.

Aluminum(III) selective potentiometric sensor based on morin in poly(vinyl chloride) matrix.

Al(3+) selective sensor has been fabricated from poly(vinyl chloride) (PVC) matrix membranes containing neutral carrier morin as ionophore. Best performance was exhibited by the membrane having composition as morin:PVC:sodium tetraphenyl borate:tri-n-butylphosphate in the ratio 5:150:5:150 (w/w, mg). This membrane worked well over a wide activity range of 5.

Manganese (II) selective PVC based membrane sensor using a Schiff base.

N,N',N'',N'''-1,5,8,12-tetraazadodecane-bis(salicylaldiminato)(H(2)L) has been used as ionophore for preparing Mn(2+) selective sensor. Membranes of different composition with regard to ratio of H(2)L:PVC:NPOE:NaTPB have been prepared and investigated. The best performance was obtained with the membrane of composition 10:150:150:10 (H(2)L:PVC:NPOE:NaTPB) (w/w; mg).

An iron(III) ion-selective sensor based on a mu-bis(tridentate) ligand.

A mu-bis(tridentate) ligand named 2-phenyl-1,3-bis[3'-aza-4'-(2'-hydroxyphenyl)-prop-4-en-1'-yl]-1,3-imidazolidine (I) has been synthesized and scrutinized to develop iron(III)-selective sensors. The addition of sodium tetraphenyl borate and various plasticizers, viz., chloronaphthalene, dioctylphthalate, o-nitrophenyl octyl ether and dibutylphthalate has been used to substantially improve the performance of the sensors.
