Entomological measures of transmission are important metrics specified by the World Health Organization to document the suppression and interruption of transmission of Onchocerca volvulus, the causative agent of onchocerciasis. These metrics require testing of large numbers of vector black flies. Black fly collection has relied on human landing collections, which are inefficient and potentially hazardous. As the focus of the international community has shifted from onchocerciasis control to elimination, replacement of human landing collections has become a priority...

We report the case of a 7-year old girl presenting with sub-occlusive syndrome associated with acute paroxysmal abdominal pain at the level of the upper abdomen, vomiting and no evacuation of faeces. Physical examination showed discomfort with palpation of the upper abdomen. Abdominal ultrasound showed poorly limited intraperitoneal tissue formation without vascular features on doppler, exercising a mass effect on the neighborhood structures; mesenteric vessels were in their normal position. This mass on CT scan scorresponded to a well limited lipomatous formation exercising a mass effect on the caecum associated with volvulus of the small intestine...

Sigmoid volvulus (SV) is a rare colonic obstruction in which the sigmoid colonwraps around itself. The principal strategy for the treatment of uncomplicated SV is emergency endoscopic detorsion, while emergency surgery is needed in complicated SV with bowel gangrene, bowel perforation, peritonitis, or unsuccessful endoscopic treatment. In the endoscopic examination of SV, endoscopic detorsion is performed if the bowels are viable, while emergency surgery is needed if the bowels are gangrenous. However, the treatment approach is not clear when endoscopic examination reveals borderline bowel ischemia, and in this short report, the possible treatment strategies are discussed...

Ischemic necrosis is a feared complication of acute gastric volvulus, occurring in 11% of patients presenting with the condition and responsible for mortality in 30%. In such cases, there are few well-validated options for surgical reconstruction. We present the case of a 77-year-old woman with intraabdominal mesenteroaxial gastric volvulus with segmental ischemic gastric necrosis who underwent wedge gastrectomy and hand-sewn gastrogastrostomy. She did well postoperatively and experienced no significant gastrointestinal complications...

BACKGROUND: Onchocerciasis is one of the tropical neglected diseases (NTDs) caused by the nematode Onchocerca volvulus. Control strategies currently in use rely on mass administration of ivermectin, which has marked activity against microfilariae. Furthermore, the development of resistance to ivermectin was observed. Since vaccine and safe macrofilaricidal treatment against onchocerciasis are still lacking, there is an urgent need to discover novel drugs. This study was undertaken to investigate the anthelmintic activity of Lophira lanceolata on the cattle parasite Onchocerca ochengi and the anthelmintic drug resistant strains of the free living nematode Caenorhabditis elegans and to determine the phytochemical profiles of the extracts and fractions of the plants...

In the search for potential vaccine candidates for the control of human lymphatic filariasis, we recently identified calponin-like protein, that regulates actin/myosin interactions, in a proinflammatory fraction F8 (45.24-48.64kDa) of Brugia malayi adult worms. In the present study, the gene was cloned, expressed, and the recombinant Calponin of B. malayi (r-ClpBm) was prepared and characterized. r-ClpBm bears homology with OV9M of Onchocerca volvulus, a non-lymphatic filariid that causes loss of vision and cutaneous pathology...

OBJECTIVE: The objective of our study was to assess the utility of CT features in the diagnosis of cecal volvulus. MATERIALS AND METHODS: Forty-three patients undergoing CT for cecal volvulus and with surgical or clinical follow-up were included. Two radiologists (11 years and 1 year of experience) evaluated CT examinations for the following: whirl sign, abnormal cecal position, "bird beak" sign, severe cecal distention, mesenteric engorgement, a newly described "central appendix" sign (defined as abnormal appendix position near midline), and overall impression for cecal volvulus...

We present a 4-week-old neonate with acute onset of bloody stools and abdominal distention. Point-of-care ultrasound performed in the emergency department allowed for rapid diagnosis of a large amount of free intra-abdominal fluid, which together with the physical findings, prompted emergent operative exploration revealing chylous ascites. Although no areas of active volvulus were identified intraoperatively, findings in the case were suggestive of small bowel volvulus and deemed as the most likely etiology for this patient's presentation...

Malrotation of the midgut is generally regarded as a paediatric pathology. It is rare in adults. Patients may present with symptoms of acute bowel obstruction or chronic abdominal pain. Barium study, Contrast Enhanced Computed Tomography (CECT), Magnetic Resonance Imaging (MRI), diagnostic laparoscopy and sometimes explorative laparotomy are used for diagnosis. Ladd's procedure through the open approach has been the treatment of choice for complete malrotation of midgut, however there are reports on successful outcome for both complete and incomplete malrotation after laparoscopic approach as well...

Ivermectin-based mass drug administration (MDA) programs have achieved remarkable success towards the elimination of onchocerciasis and lymphatic filariasis. However, their full implementation has been hindered in Central Africa by the occurrence of ivermectin-related severe adverse events (SAEs) in a subset of individuals with high circulating levels of Loa loa microfilariae. Extending MDA to areas with coincident L. loa infection is problematic, and inexpensive point-of-care tests for L. loa are acutely needed...

Gastric dilatation volvulus (GDV) was identified in six adult maned wolves ( Chrysocyon brachyurus ) housed at the Smithsonian Conservation Biology Institute in Front Royal, Virginia, and the Dickerson Park Zoo in Springfield, Missouri. Four individuals were found dead in their enclosures, and GDV was diagnosed postmortem based on radiographic and necropsy findings. Two individuals were diagnosed with GDV antemortem, with one wolf surviving following surgical intervention and supportive management. A concurrent splenic torsion was identified in three of six cases...

Anesthesia and surgery in cetaceans have inherent risks and have rarely been utilized as viable treatment options. This report represents the first known multidisciplinary team approach to emergency laparotomy in a compromised, 22-yr-old, female Pacific white-sided dolphin ( Lagenorhynchus obliquidens ). The inciting clinical signs and ancillary diagnostics were consistent with a mechanical ileus. Although no torsion or obstruction was apparent during surgery, severe enteritis and peritonitis were noted. Postoperatively, the animal was maintained on aggressive medical management with continuous supportive care until succumbing 3 days later with clinical pathology indicative of terminal sepsis and profound inflammation...

BACKGROUND: Treatment of onchocerciasis using mass ivermectin administration has reduced morbidity and transmission throughout Africa and Central/South America. Mass drug administration is likely to exert selection pressure on parasites, and phenotypic and genetic changes in several Onchocerca volvulus populations from Cameroon and Ghana-exposed to more than a decade of regular ivermectin treatment-have raised concern that sub-optimal responses to ivermectin's anti-fecundity effect are becoming more frequent and may spread...

Onchocerciasis, a neglected tropical disease prevalent in western and central Africa, is a major health problem and has been targeted for elimination. The causative agent for this disease is the human parasite Onchocerca volvulus. Onchocerca ochengi and Litomosoides sigmodontis, infectious agents of cattle and rodents, respectively, serve as model organisms to study filarial nematode infections. Biomarkers to determine infection without the use of painful skin biopsies and microscopic identification of larval worms are needed and their discovery is facilitated by an improved knowledge of parasite-specific metabolites...

OBJECTIVE To determine whether specific alleles of candidate genes of the major histocompatibility complex (MHC) and innate immune system were associated with gastric dilatation-volvulus (GDV) in Great Danes. ANIMALS 42 healthy Great Danes (control group) and 39 Great Danes with ≥ 1 GDV episode. PROCEDURES Variable regions of the 2 most polymorphic MHC genes (DLA88 and DRB1) were amplified and sequenced from the dogs in each group. Similarly, regions of 3 genes associated with the innate immune system (TLR5, NOD2, and ATG16L1), which have been linked to inflammatory bowel disease, were amplified and sequenced...

Intestinal cystic duplications are rare congenital anomalies, with an estimated incidence of approximately 1:4500 autopsies. The etiopathogenesis is uncertain. These duplications are cystic, tubular or diverticular structures lined with gastrointestinal mucosa. They share a common smooth muscle wall with the gastrointestinal tract but usually their lumens do not communicate with each other. Gastric duplication cysts represent 7-9% of the gastrointestinal tract duplication. They can be diagnosed prenatally by fetal ultrasound; magnetic resonance imaging characterizes the cyst and excludes other malformations...
