The possibility of concomitant immunity and its potential mechanisms in Onchocerca volvulus infection were examined by analyzing cytokine and antibody responses to infective larval (third-stage larvae [L3] and molting L3 [mL3]), adult female worm (F-OvAg), and skin microfilaria (Smf) antigens in infected individuals in a region of hyperendemicity in Cameroon as a function of age. Peripheral blo...

INTRODUCTION Colonic volvulus is a rare entity associated with high mortality rates. Most studies come from areas of high endemicity and are limited by small numbers. No studies have investigated trends, outcomes, and predictors of mortality at the national level. METHODS The Nationwide Inpatient Sample 2002-2010 was retrospectively reviewed for colonic volvulus cases admitted emergently. Pat...

The macrofilaricidal effects of local infiltration of high concentrations of chloroquine into the capsule of onchocercal nodules on adult worms of Onchocerca volvulus was determined. Six weeks post infiltration, histological examination of single nodules showed all adult worms to be dead. With nodule conglomerates, there was localized action of chloroquine only on the adult worms in the infiltr...

Factors that affect the propensity of a simuliid species to act as a host to Onchocerca volvulus and to naturally transmit this filarial worm in nature are discussed. Presence or absence of a cibarial armature is believed to be a major factor that has been previously overlooked and this is considered in relation to the choice of control methods currently advocated for onchocerciasis. The curren...

introduction the use of an umbilical catheterization is a usual practice in neonatal units. the insertion of the catheter has potential complications. case presentation here, we report on our observation of a seven-day-old female newborn admitted for an abdominal distention and vomiting bile. initially, diagnosis was midgut volvulus, for which an operation was performed. during the surgery, no ...

The colon involved with the sigmoid volvulus is much thicker than the normal colon. It is easy to handle and holds sutures well. Patients who have sigmoid-colon volvulus do not have much faecal loading. Most of the distension is gaseous. In the hands of experienced surgeons primary anastomosis can be done after sigmoid colectomy with safety and excellent results.

The filarial parasite Loa loa overlaps geographically with Onchocera volvulus and Wuchereria bancrofti filariae in central Africa. Accurate information regarding this overlap is critical to elimination programs targeting O. volvulus and W. bancrofti. We describe a case of loiasis in a traveler returning from Bioko Island, Equatorial Guinea, a location heretofore unknown for L. loa transmission.

Small gut volvulus is rare in adults and usually presents with acute intestinal obstruction. We report a 25-year-old man with primary small gut volvulus who presented with hematemesis. The gangrenous gut was resected at laparotomy. He is well 3 months later.
