Onchocerca volvulus: immunohistochemical and immunoelectron microscopical distribution of a polyamine oxidizing enzyme.
We studied the distribution of a polyamine oxidizing enzyme (PAO) in Onchocerca volvulus and other nematode parasites by immunohistochemistry and electron microscopy with immunogold technique using a polyclonal antiserum raised against purified PAO from Ascaris suum. In adult O. volvulus the protein was localized in the outer zone and the area of the basal labyrinth of the hypodermis and occasionally in the outer zone of the uterine epithelium. Further, the fluid in the body cavity was strongly stained. No specific labelling was observed in the cuticle, muscles, epithelia of intestine, ovaries, testis and vas deferens or in sperm, oocytes and embryos. Third-stage larvae of O. volvulus in Simulium soubrense showed strong staining; the same was observed in Anisakis sp. larvae, where the inner and outer zone of the hypodermis were strongly labelled. All mature, intact and dead microfilariae in nodules, skin and lymph nodes were well stained and it was possible to show that the cytoplasm of the hypodermal cells, but not the mitochondria, nuclei or other organelles of muscle cells, was preferentially labelled by immunogold particles. Investigation of adult A. suum presented specific labelling of the hypodermis, but the basal labyrinth was more strongly marked than the outer zone.
The fine structure of adult Onchocerca volvulus. V. The digestive tract and the reproductive system of the female worm.
The morphology of the oesophagus, the intestine, the ovary, the uterus, the vagina and some inclusions in the body cavity are described in worms of different ages. The oesophagus wall comprises mostly muscle fibrils and a few glandular regions located only in the posterior portion. In the lumen, some material was found. From the anterior to the posterior end, the lumen of the intestine is reduced. The plasm of the intestinal cells of older worms is filled with concentric spherules containing iron, which are absent in mature but not full-grown worms. The ovarial cells contain in their outer region some fibrils and in the inner region some dense bodies. The ring-muscles of the uterine wall run in clefts of the basal lamina. They usually have accumulated iron containing bodies. In the final portion of the uterus and in the vagina the muscles are very thick. A comparison of the general morphology of the midbody regions of young, not full-grown worms, one less than five years old worm and some worms at least five years old is given.
[Chronic intestinal pseudo-obstruction syndrome in infants and associated anomalies].
The authors report 2 cases of functional intestinal pseudo-obstruction in infancy associated with intestinal and urologic anomalies. In the first case many intestinal obstructions occurred from the age of 3 weeks and the boy was operated on at 14 months of age. A short small bowel and an intestinal malrotation were found at surgery; the alimentary canal was completely aperistaltic, and an ileostomy was performed. Further operations were carried out, for obstruction due to adhesions, and lastly to perform another ileostomy. An antenatal diagnosis of megacystis had been made with ultrasonography. In the second case, the pseudo-obstruction syndrome occurred at the age of 1 month, due to a volvulus of the small bowel with malrotation. A second operation, one month later because of lack of intestinal transit showed an aperistaltic bowel and a colostomy was performed. The intestinal continuity was set up again at the age of 9 months and a fractional feeding was started. A megacystis was found during urologic investigations. Growth is correct for both children at 3 years of age. A review of the literature allowed to list the most frequent digestive or extradigestive anomalies associated with this syndrome.
Duodenal atresia.
The intestinal obstruction of duodenal atresia needs urgent differential diagnosis from malrotation with its risk of midgut volvulus and gangrene. There is an uncommon variant with a high incidence of familial recurrence, and a significant association with Down's syndrome, although the majority of the babies are otherwise normal. Oblique end-to-end anastomosis around the atresia is the preferred treatment and has a high success rate.

Intestinal obstruction at a provincial hospital in Kenya.
OBJECTIVE: To determine the presentation, aetiological pattern, management and outcome of intestinal obstruction at the Central Provincial General Hospital, Nyeri, Kenya. DESIGN: A descriptive retrospective study. SETTING: Surgical Department, Central Provincial General Hospital, Nyeri, Kenya. SUBJECTS: All patients who were admitted and operated on for intestinal obstruction in the surgical department of the above hospital between January 1992 and May 1999. RESULTS: A total of 139 patients were studied. There were 102 males and 37 females giving a male:female ratio of 2.8:1. The age range was two days to 85 years with the majority (43.2%) of the patients being in the age group 0-10 years. Vomiting and abdominal pain were the commonest symptoms while abdominal distension and abdominal tenderness were the leading signs. Abount seventy of the patients had any form of investigation with plain abdominal x-ray being the leading investigation. Sigmoid volvulus, external herniae, adhesions and bands and ileo-colic intussusception were the commonest causes of bowel obstruction. About a third (32.4%) of the patients were found to have gangrenous gut. Sixty three complications were recorded in 47 patients, with the leading complication being death (17.3%) followed by wound infection (14.4%). CONCLUSION: Five leading causes of intestinal obstruction in Nyeri, Kenya, are: sigmoid volvulus, external herniae, adhesions and bands, ileocolic intussusception and small bowel volvulus.
