Tropical paediatric intussusception--is it a different disease entity?

The presentation of intussusception in children in Zaria, Nigeria has been studied with the aim of identifying any features that may differentiate it from that which obtains in temperate countries. Our data reveal no difference in age of peak incidence, sex ratio, absence of preceding upper respiratory infection or lack of significant seasonal variation. However, there is an unusually high incidence (41%) of caecocolic intussusception. It is believed that this may account for other observed features, such as the low occurrence of constipation and other evidence of intestinal obstruction, and the relatively high incidence of "painless" intussusception and sub-acute or chronic intussusception. Twenty-nine per cent of the patients had only one or two of the usual diagnostic features of the disease and this contributed to delayed diagnosis. In all but two patients the condition was idiopathic and there was no evidence to implicate bacterial enteritis or parasitic infestation in the aetiology of the disease.

Mucocele of the vermiform appendix with sonographic appearance of an adnexal mass.

Mucocele of the vermiform appendix is caused by mucus retention in its lumen, due to obstruction or hyperproduction. Appendiceal malignancy can be the underlying cause, making accurate preoperative diagnosis imperative. In women, it can sometimes present as an adnexal mass. A rare case of an appendiceal mucocele is presented, mimicking a cystic tumor of the right adnexum, both clinically and ultrasonographically. In addition, serum levels of CA-125 were increased. This is the first case of a mucocele of the appendix simulating an adnexal mass on ultrasound with increased levels of CA-125 to be reported. This clinical entity should be considered in patients presenting on ultrasound with a right-sided adnexal mass as a rare potential diagnosis.

Laparoscopic surgery in women with a clinical diagnosis of acute appendicitis.

OBJECTIVES: To assess the routine use of diagnostic laparoscopy and laparoscopic appendicectomy in women with a clinical diagnosis of acute appendicitis. METHODS: Women who presented with a clinical diagnosis of acute appendicitis between 1 January 1992 and 31 August 1993 were prospectively assessed and 107 underwent diagnostic laparoscopy. RESULTS: Appendicitis was confirmed in 63 women (59%) and no diagnosis could be made in seven (6%). An alternative diagnosis, most commonly a gynaecological disorder, was made in 37 women (35%). Twenty-eight women with an alternative diagnosis (76%) did not require a laparotomy. Seventy-three patients had a laparoscopic appendicectomy, with an 8% conversion rate to an open operation. The morbidity rate for laparoscopic procedures was 3%, the median inpatient stay was two days and the median time to return to normal activities was eight days. CONCLUSIONS: Diagnostic laparoscopy should be performed in women who present with a clinical diagnosis of acute appendicitis to confirm the diagnosis, reduce the rate of unnecessary appendicectomy and avoid an unnecessary laparotomy. When acute appendicitis is confirmed, appendicectomy may be performed laparoscopically.

[Pathological changes of early intestinal tuberculosis].

OBJECTIVE: To probe into the characteristics of pathological changes of early intestinal tuberculosis. METHOD: Three cases of early intestinal tuberculosis proved by colonoscopy were reported and analyzed. RESULT: Hyperemia and edema of the ileocecal mucosa were found. The involved mucosa looked friable and eroded, which was covered by fibrinopurulent exudates or forsty white mucus. The ileocecal valve was edematous and deformed. Tuberculous tubercles were found in intramucosal tissue under microscopy. Neither ulceration nor fiberous hypertrophy was found. CONCLUSION: It shows important significance to recognize the pathological manifestations of early intestinal tuberculosis for diagnosis of the disease.

[Mucocele of the appendix. Retrospective study of 10 cases].

PURPOSE: The purpose of our work was to assess the value of abdominal sonography (US) and computed tomography (CT) in the preoperative diagnosis of appendiceal mucocele. MATERIAL: and methods. We retrospectively reviewed 10 cases of mucocele of the appendix, 7 cases without pseudomyxoma peritonei, and 3 cases with pseudomyxoma peritonei. All cases were investigated radiologically by plain film and US, barium enema was performed in 3 cases and CT in 5 cases. RESULTS: Mucoceles of the appendix are rare and their clinical presentation is not specific. US confirms the appendicular involvement, but often poses the differential diagnosis with acute inflammation, abscess or localized appendicular peritonitis. CT appears as a mandatory examination since it allows accurate preoperative diagnosis period. In this series, the diagnosis was made preoperatively in the 5 cases where CT had been performed. CONCLUSION: US is useful to confirm the abnormal pattern of the appendix but does not allow accurate diagnosis of mucocele. CT is more specific and accurate for diagnosis of mucocele of the appendix.

Mortality causes of owl monkeys (Aotus nancymae and Aotus vociferans) in captivity.

To determine the main causes of death in "owl monkeys" (Aotus nancymae and A. vociferans) in captivity, 115 necropsies were performed. According to the macroscopic findings and clinical data, results are as follow: acute lobular pneumonia (25.2%), chronic nephropathy (10.4%), acute catarrhal enteritis (8.7%), acute hemorrhagic enteritis (7%), acute toxic hepatitis (5.2%), trauma (5.2%), and others.

Contribution to the question of relationships between Enterobius vermicularis (L.) and inflammatory processes in the appendix.

We evaluated a bioptic material of appendices from the hospital in Ceské Budĕjovice, obtained from 1977-1981. Of these, 2173 appendices were removed as cases of a clinical appendicitis, 788 for preventive reasons. In the cases of a clinical appendicitis with the incidence of pin worms in the appendix, the histological picture displayed significantly more chronical, inflammatory changes than in acute cases (test chi 2), while in cases of a clinical appendicitis without the presence of pin worms, we found more acute than chronical forms of inflammations. Our results are supported also by an analysis of preventively removed appendices, where again more chronical, inflammatory changes were found in appendices with pin worms.
