INTRODUCTION: The aim of the present study was to evaluate clinical presentation and management of sigmoid volvulus in children. Sigmoid volvulus is one of the three leading causes of acute obstruction of the colon and is between 50 and 90% of all large bowel volvulus. In the pediatric population only 3 to 5% of bowel obstructions are caused by volvulus and there are less than 100 cases reported in the literature. The presence of a redundant sigmoid with a narrow mesentery (dolicosigmoide) is a prerequisite for the volvulus formation...

CASE DESCRIPTION A 13-year-old female green iguana (Iguana iguana) was examined because of a 6-day history of vomiting, anorexia, and lethargy and a 4-day history of decreased fecal and urate output. CLINICAL FINDINGS Physical examination revealed a distended abdomen, signs of depression, pallor, tachycardia, harsh lung sounds, and vomiting. Abdominal radiographs revealed gas distention of the stomach and small intestine with fluid lines evident on the lateral view. Plasma biochemical analysis indicated hypochloremic metabolic alkalosis, hyperglycemia, and hyperuricemia...

Human onchocerciasis (river blindness) is one of the few neglected tropical diseases (NTDs) whose control strategies have been informed by mathematical modelling. With the change in focus from elimination of the disease burden to elimination of Onchocerca volvulus, much remains to be done to refine, calibrate and validate existing models. Under the impetus of the NTD Modelling Consortium, the teams that developed EPIONCHO and ONCHOSIM have joined forces to compare and improve these frameworks to better assist ongoing elimination efforts...

The endosymbiotic bacteria, Wolbachia, induce neutrophilic responses to the human helminth pathogen Onchocerca volvulus. The formation of Neutrophil Extracellular Traps (NETs), has been implicated in anti-microbial defence, but has not been identified in human helminth infection. Here, we demonstrate NETs formation in human onchocerciasis. Extracellular NETs and neutrophils were visualised around O. volvulus in nodules excised from untreated patients but not in nodules from patients treated with the anti-Wolbachia drug, doxycycline...

Introduction. Gallbladder volvulus is a rare, potentially fatal condition unless diagnosed and treated early. Choledochal cysts are rare congenital malformations of the biliary tree predisposing to different pathologies and posing the risk of degradation into cholangiocarcinoma and gallbladder cancer. Dealing with both diseases at once has not been published yet in the literature. Presentation of Case. We report a case of gallbladder volvulus in an elderly female who happened to have a concomitant type I choledochal cyst...

Colonic volvulus usually occurs as a single event that can affect various parts of the colon. The usual sites affected being the sigmoid colon (75%) and the caecum (22%). The phenomenon of multiple sites simultaneously undergoing volvulus is an extremely rare occurrence. Synchronous double colonic volvulus is extremely rare and to the best of our knowledge, this is the 4th reported case of simultaneous sigmoid and caecal volvulus in the English literature. The clinical presentation and the radiological findings are that of large bowel obstruction...

BACKGROUND: Genetic surveillance of the human filarial parasite, Onchocerca volvulus, from onchocerciasis endemic regions will ideally focus on genotyping individual infective larval stages collected from their intermediate host, Simuliid blackflies. However, blackflies also transmit other Onchocerca species, including the cattle parasite O. ochengi, which are difficult to distinguish from the human parasite based on morphological characteristics alone. This study describes a versatile approach to discriminate between O...

Torsion of a uterine leiomyoma is a rare complication that can be life threatening because of ischemia or necrosis. This condition may also lead to gastrointestinal complications such as obstruction or, more rarely, small bowel volvulus. Its diagnosis is difficult and can be facilitated with the use of computed tomography or magnetic resonance imaging. Treatment is based on emergency surgical resection of the twisted uterine leiomyoma and detorsion of the small bowel volvulus.

BACKGROUND: There is compelling evidence that not only do anti-filarials significantly reduce larval forms, but that host immune responses also contribute to the clearance of filarial parasites; however, the underlying mechanisms have not been fully elucidated. MAIN TEXT: Filarial infections caused by Wuchereria bancrofti and Brugia species (lymphatic filariasis) and Onchocerca volvulus (onchocerciasis) affect almost 200 million individuals worldwide and pose major public health challenges in endemic regions...

BACKGROUND: Congenital diaphragmatic hernia (CDH) affects 1 in 3000 live births. Modern management strategies include delayed repair of the diaphragm to permit pre-operative optimization of cardiorespiratory status. We describe a cohort of neonates in whom early emergency operative intervention was required for potentially fatal intestinal compromise. METHODS: A retrospective review was performed of all neonatal CDH patients managed at a tertiary center in an 8-year period (2005-2012)...

PURPOSE: Although the principles of the Ladd's procedure for intestinal malrotation in children have remained unchanged since its first description, in the era of minimally invasive surgery it is controversial whether laparoscopy is advantageous over open surgery. The aim of our study was to determine whether the surgical approach for the treatment of malrotation had an impact on patient outcome. METHODS: Using a defined strategy (PubMed, Cochrane, Embase and Web of Science MeSH headings), two investigators independently searched for studies comparing open versus laparoscopic Ladd's procedure in children...

Percutaneous endoscopic colostomy (PEC) is a minimally invasive endoscopic procedure that offers an alternative treatment for high-risk patients with sigmoid volvulus or intestinal pseudo-obstruction who have tried conventional treatment options without success or those who are unfit for surgery. The procedure acts as an irrigation or decompressing channel and provides colonic 'fixation' to the anterior abdominal wall. The risk of complications highlights the importance of informed consent for patients and relatives...

Wandering spleen and gastric volvulus are two rare entities that have been described in association with congenital diaphragmatic hernia. The diagnosis is difficult and any delay can result in ischemia and necrosis of both organs. We present a case of a 13-year-old girl, previously operated on for anterior diaphragmatic hernia and intrathoracic gastric volvulus, that presented to our service for a subdiaphragmatic gastric volvulus recurrence associated with a wandering spleen. In this report we reviewed the literature, analyzing the clinical presentation, diagnostic assessment, and treatment options of both conditions, in particular in the case associated with diaphragmatic hernia...

Onchocerciasis is one of the two filarial helminth "neglected tropical diseases" (the other being lymphatic filariasis) that has been targeted for geographically local elimination followed by global eradication. The last known areas of Onchocerca volvulus transmission in the Americas have recently been reported to be eliminated. In contrast, achieving metrics for interruption of O. volvulus transmission in Africa, thus removing the requirement for continued monitoring and mass drug administration (MDA) with ivermectin, has been more challenging...

Onchocerciasis is a parasitic, vector borne disease caused by the filarial nematode Onchocerca volvulus. More than 99% of the population at risk of infection live in Africa. Onchocerciasis control was initiated in West Africa in 1974 with vector control, later complemented by ivermectin mass drug administration and in the other African endemic countries in 1995 with annual community directed treatment with ivermectin (CDTI.) This has significantly reduced infection prevalence. Together with proof-of-concept for onchocerciasis elimination with annual CDTI from foci in Senegal and Mali, this has resulted in targeting onchocerciasis elimination in selected African countries by 2020 and in 80% of African countries by 2025...

Colonoscopy is widely performed for the diagnosis and treatment of various colonic disorders and the screening and surveillance of colorectal neoplasia. According to research evidence, up to one-third of patients had at least 1 minor and transient gastrointestinal symptom after colonoscopy. Although severe complications developed uncommonly, they are potentially serious and life threatening. Here, we present the case of a 95-year-old man with chronic obstructive pulmonary disease who developed bilateral tension pneumothorax during therapeutic colonoscopy for sigmoid volvulus...

Cecal volvulus is characterized by torsion of the cecum around its own mesentery. However, cecal volvulus rarely develops soon after elective laparoscopic cholecystectomy. We report on a case of cecal volvulus that developed in a 54-year-old women 1 day after elective laparoscopic cholecystectomy and was successfully treated via colonoscopic decompression. The symptoms gradually improved in conjunction with recovery from postoperative ileus. Whether the incidence of volvulus has increased with the use of laparoscopic procedures, including laparoscopic cholecystectomy, has yet to be determined...

Gastrointestinal duplications can affect any part of the alimentary tract and are notorious for their variable presentation. Their association with malrotation and midgut volvulus is rare. We describe an 8-year old boy presented with episodes of abdominal pain. Radiological workup showed whirlpool sign and abnormal relationship of mesenteric vessels. At operation, malrotation with chronic volvulus was found. Incidentally, a jejunal communicating duplication cyst was also noted.
