BACKGROUND: Appendectomy is the most common emergency surgery performed in the USA. Removal of a non-inflamed appendix during unrelated abdominal surgery (prophylactic or incidental appendectomy) can prevent the downstream risks and costs of appendicitis. It is unknown whether such a strategy could be cost saving for the health system. METHODS: We considered hypothetical patient cohorts of varying ages from 18 to 80, undergoing elective laparoscopic abdominal and pelvic procedures...

BACKGROUND: Acute appendicitis (AA) is the most common cause of acute abdomen during pregnancy. Most of the signs of appendicitis are also found during normal pregnancy period, however, and diagnosis of appendicitis during pregnancy remains challenging. The aim of the current study was to report our clinical experience of AA during pregnancy and investigate optimal management of this difficult situation. METHODS: Records of 20 pregnant women with diagnosis of AA who underwent appendectomy between 2005 and 2015 were included in this study...

BACKGROUND: Acute appendicitis (AA) is the most common reason for abdominal surgery in the world. The aim of this study was to evaluate the effect of medical treatment on histological findings in rabbits with AA. METHODS: Twenty-one male New Zealand rabbits were divided into 3 groups: appendix ligation and medical treatment, appendix ligation and no treatment, and control group, which underwent only laparotomy. RESULTS: In appendix ligation without treatment group, AA findings were much more severe...

Pulmonary sequestration is a rare and usually asymptomatic congenital anomaly. Optimal management of this condition is still a subject of debate, including superiority of surgical resection or angiographic embolization of the aberrant arterial vessel. Presently described is rare case of a 51-year-old male who presented with hemoptysis related to pulmonary sequestration associated with acute right lower quadrant abdominal pain caused by perforated appendicitis.

BACKGROUND: Laparoscopic appendectomy (LA) has obtained wide acceptance over the last two decades. However, some studies suggest that there is an increased rate of intraabdominal abscess (IAA) when is compared with open appendectomy. Since postoperative IAA is associated with high morbidity, identifying predictive factors of this complication may help to prevent it. The aim of this study was to identify preoperative and intraoperative risk factors for IAA after LA. METHODS: From January 2005 to June 2015, all charts of consecutive patients underwent to LA were revised...

Dimerization of G protein-coupled receptors (GPCR) may play an important role in maturation, internalization, signaling and/or pharmacology of these receptors. However, the location where dimerization occurs is still under debate. In our study, variants of Ste2p, a yeast mating pheromone GPCR, were tagged with split EGFP (enhanced green fluorescent protein) fragments inserted between transmembrane domain seven and the C-terminus or appended to the C-terminus. Bimolecular Fluorescence Complementation (BiFC) assay was used to determine where receptor dimerization occurred during protein trafficking by monitoring generation of EGFP fluorescence, which occurred upon GPCR dimerization...

Human islet amyloid polypeptide (hIAPP), also known as amylin, is a 37 residue peptide hormone that is stored and co-secreted with insulin. hIAPP plays a pivotal role in type 2 diabetes and is the major component of amyloid deposits found in the pancreas of patients afflicted with the disease. The self-assembly of hIAPP and the formation of amyloid is linked to the death of insulin producing -cells. Recent findings suggest soluble hIAPP oligomers are the cytotoxic species responsible for -cell loss whereas amyloid fibrils themselves may indeed be innocuous...

Meckel's diverticulum is the most common congenital abnormality of the small intestine that results from incomplete closure of the vitelline (omphalo-mesenteric) duct. This true diverticulum, ~2 ft from the ileocecal valve commonly found on the anti-mesenteric border of the ileum, is benign and majority asymptomatic. Diagnosis challenges arise when it became inflamed or presented in following ways, for example, haemorrhage (caused by ectopic pepsin-and hydrochloric acid-secreting gastric mucosa), intestinal obstruction (secondary to intussusception or volvulus) or the presence of diverticulum in the hernia sac (Littre's hernia)...

BACKGROUND: Nonoperative treatment of acute appendicitis is embraced by many surgical teams, driven by low to moderate quality randomized studies that support noninferiority of antibiotics versus appendectomy for treatment of acute uncomplicated appendicitis. Several flaws of these studies have emerged, especially in the recruitment strategy and in the diagnostic criteria that were used. The growing confidence given to antibiotics, together with the lack of reliable criteria to distinguish between uncomplicated and perforated appendicitis, exposes patients with perforated appendicitis to the likelihood to be treated with antibiotics instead of surgery...

BACKGROUND: Confirmation of appendicitis in children often requires CT. A focused CT scan that is limited to the lower abdomen/pelvis might help to reduce radiation exposure. OBJECTIVE: To determine the position of the appendix relative to the umbilicus and derive a height-adjusted threshold for a focused CT that would identify most appendices. MATERIALS AND METHODS: We conducted a retrospective study of children younger than 18 years who underwent a CT scan for suspected appendicitis...

BACKGROUND: Dengue is the most important human viral disease transmitted by mosquitoes. It can be asymptomatic or it can present in any of its 3clinical forms: Dengue fever, dengue haemorrhagic fever and dengue shock syndrome. However, some atypical manifestations have been reported in surgical emergencies caused by acute appendicitis in patients with dengue fever. CLINICAL CASE: We report the case of an 18-year-old Mexican male who presented to the emergency department of the General Hospital of Culiacan, Sinaloa, with symptoms of dengue fever, accompanied by crampy abdominal pain with positive Rovsing and Dunphy signs...

Paramagnetic complexes of gadolinium(III) with acyclic or macrocyclic chelates are the most commonly used contrast agents (CAs) for magnetic resonance imaging (MRI). Their purpose is to enhance the relaxation rate of water protons in tissue, thus increasing the MR image contrast and the specificity of the MRI measurements. Current clinically approved contrast agents are low molecular weight molecules that are rapidly cleared from the body. The use of dendrimers as carriers of paramagnetic chelators can play an important role in the future development of more efficient MRI contrast agents...

A wild-type vertebrate embryo first generates its head and then extends its main body axis by successively appending trunk and tail. This rostro-caudal (head-to-tail) development is initiated by a set of morphogenetic movements known as gastrulation that recruits multipotent cells into one of the three morphologically distinct germ layers: ectoderm, endoderm, and mesoderm. These primordial tissues go on to form complementary sets of connective tissues and organs to build the head and at least some of the trunk...

BACKGROUND: Right iliac vein thrombosis is uncommon in pregnancy. Nonetheless, when it does occur, its presentation could be very unspecific with important diagnostic challenges and this could have negative therapeutic consequences especially in a resource limited setting. CASE PRESENTATION: The historical, clinical and laboratory data of a 30 year old G2P1001 woman of African ethnicity at 11 weeks of gestation pointed towards a right iliac vein thrombosis missed for an acute appendicitis with subsequent appendectomy and failure to cure...

The authors report the case of a 12-year-old boy admitted to the surgical emergency department of Charles de Gaulle Paediatric Teaching Hospital of Ouagadougou for acute abdominal pain. A strangulation of the terminal ileum by a tumour-like appendix wound around the bowel loop was seen during operation. The histological examination of the removed appendix disclosed eggs of Schistosoma haematobium and concluded to bilharzian appendicitis. A course of praziquantel treatment was instituted, and the patient underwent an event-free recovery...

BACKGROUND: Primary wound closure following laparotomy for peritonitis is generally believed to be associated with wound complications and long hospital stay. Open wound management has long been the most common practice after laparotomy for peritonitis. Primary closure (PC), however, has recently been advocated to reduce cost and morbidity. This study determined the incidence and severity of wound complications and their impact on hospital stay and overall outcome when PC of abdominal wounds is done following laparotomy for peritonitis...
