We have encountered two patients with volvulus of the small intestine at the ileocolic anastomosis, occurring after jejunoileal bypass. This uncommon complication is generally seen many months after bypass and may be difficult to diagnose. Barium enema examination was helpful in one patient. If there are acute, severe abdominal symptoms, mechanical obstruction and early operation should be considered. Attention has been called to other intestinal syndromes with obstructive features developing after jejunoileal bypass, and these have been compared.

The results of the radiological examination of 330 children following oral administration of barium are reported. It is pointed out that if one just takes into account the undoubted organic diseases, only a few children would benefit from the examination; in our case only 9 of them (a gastric and a duodenal ulcer, a pancreas pseudocyst, 5 hiatal hernias, and a celiac disease), i.e. 3%. This is not very satisfactory from a practical point of view. This situation improves radically when one looks for diseases usually rated as questionable: small hiatal hernia (cardiotuberositary malposition), functional disturbances of the small intestine, reactive hyperplasia of the lymphoid tissue, and chronic appendicitis. Thus we were able to offer 177 children, i.e. 53% of them, an efficacious therapy. The importance of chronic appendicitis and of functional disturbances of the small intestine as a cause of abdominal pain in children is pointed out, and their radiological symptoms are discussed. Finally the not uncommon, but not very well known disease of incomplete sigmoid volvulus is described.

A recent experience with cecal volvulus of acute and chronic types is presented. The four cases were treated surgically by both reconstructive and extirpative means with equally good results. Early diagnosis and vigorous treatment are emphasized to avoid a high mortality rate in this condition.

Seven patients with acute and progressive abdominal distension secondary to massive cecal and right colon ileus are analyzed. Five had pseudoobstruction of the colon and two had cecal volvulus. Two of the patients with pseudoobstruction and one with cecal volvulus died from preexisting diseases. Pseudoobstruction of the colon is not a rare complication of elderly, sick, bedridden patients. Differential diagnoses include cecal and sigmoid volvulus and acute gastric dilation. Initial conservative therapy is warranted if no peritoneal signs are present. If the cecal diameter is more than 12 cm, colonoscopic decompression with a fiberscope should be attempted. If unsuccessful, tube cecostomy will provide curative, life-saving therapy even if taenia splitting is present. Perforation or widely scattered areas of necrosis make resection mandatory.

In a kindred with a familial visceral myopathy, seven patients had operations seeking relief of chronic abdominal pain and other symptoms of intestinal obstruction; one patient had an 80% cystectomy and a Y-V-plasty of the bladder neck for urinary retention. Five patients with megaduodenum had bypass operations; a side-to-side duodenojejunostomy was done in four and a retrocolic gastrojejunostomy in one. Two of these died of postoperative complications, and one developed symptomatic adhesions. Two other patients who had duodenojejunostomy have done well for 6 years and 1 1/2 years respectively. One patient with dilation of the distal jejunum and proximal ileum had relief of intestinal obstructive symptoms from jejunostomy to decompress the destal jejunum. One patient who had a resection of the descending and sigmoid colon for sigmoid volvulus has done well for four years. Three of these seven patients developed peritonitis postoperatively, and two had symptomatic adhesions after operations. Duodenal aspiration from a patient who developed postoperative peritonitis grew E. coli, 10(13) colonies per ml. After review of the results of operations in other families and in our kindred, we favor side-to-side duodenojejunostomy in megaduodenum. Duodenal aspirate must be cultured before operation. Evidence of bacterial overgrowth in the aspirate should prompt appropriate antibiotic treatment to reduce the likelihood of sepsis.

Volvulus of the transverse colon is a rare condition requiring early diagnosis and treatment. In the absence of ischaemic changes within the redundant bowel, success can be anticipated with conservative fixation procedures. A case is reported which was treated by reduction, decompression and parallel colopexy. Although this disease has been infrequently reported in the past there may well be an increasing incidence with the introduction of high fibre diets and the use of the colonoscope.

Two complete days of collections and dissections of all black fly species landing on two persons infected with Onchocerca volvulus were made at monthly intervals for 13 months within a single endemic area of Guatemala. A comparison of the infective biting densities and transmission potentials showed that Simulium ochraceum was the only significant vector.

Six onchocerca-nodules from five Liberian patients were examined by electron microscopy. The bulk of cells in the centre of the nodules consists of lymphocytes and macrophages. The lymphocytes can be observed in various stages of differentiation. A major part of the macrophages shows degenerative changes with decrease of lysosomes and increase of fatty vacuoles. Near the worms epithelioid cells and giant cells can be found. Other cells in the nodule include polymorphonuclear neutrophils, eosinophils, plasma cells, and mast cells. Adult Onchocerca volvulus show the basic nematode body plan. The cuticle is subdivided into cortex and two layers with differently arranged fibrillar structures. The characteristics of the hypodermal cells are best seen in the lateral chords, in the interchordal regions the hypodermis is flattened by a muscle layer. The intestine typically contains pigment granules, the cells of the epithelium have folds of their cell membranes forming a basal labyrinth. The uterus consists of two tubes in which the development of the microfilariae from the early embryonic forms to the mature stages is examined.

A pilot study on onchocerciasis and sowda was carried out in the south-western region of the Yemen Arab Republic. Of 61 persons examined in eight villages 35 (= 57%) were found positive for microfilariae by the skin-snip method, 13 had typical manifestations of sowda, 17 had other onchocercal-suggestive skin lesions and five had subcutaneous nodules. A single larva of Simulium damnosum s.I. was collected in Wadi Barakani. Numerous larvae and pupae of S. ruficorne and S. hargreavesi were taken in fast-flowing streams in four localities. The examination of microfilariae and adult worms by scanning electron microscopy as well as the histochemical staining of microfilariae for the demonstration of acid phosphatase activity confirmed that the concerned filaria belongs to the species Onchocerca volvulus. No morphological differences could be detected between the smaller number of the examined worms from the Yemen and the extensive parasite material from Liberia, West Africa.

We present 4 patients with serious complications after retroperitoneal lymphadenectomy. Chylothorax developed in the first patient; hypertension, blindness, and paralysis of the lower extremities in the second; volvulus and necrosis around an adhesion in the right upper quadrant in the third; and small-bowel obstruction and radiation myelitis in the fourth patient. These complications and modes of treatment and prevention are discussed.
