Abstract

Acute appendicitis is the most common cause of acute abdomen requiring surgical intervention. The clinical diagnosis of acute appendicitis is not always easy due to variable symptomatology, particularly at the onset. The contributions of history-taking and physical examination in the diagnosis of acute appendicitis was studied in connection with the Research Committee of the World Organization of Gastroenterology (OMGE) survey of acute abdominal pain. Especially the suitability of diagnostic parameters in the construction of an expert system for automatic decision making was studied. The results clearly show that it is possible to construct an expert system for automatic decision making in the diagnosis of acute appendicitis.

[Acute hepatic porphyria and its neurological syndrome].

Certain of the hepatic porphyrias are classified as belonging to the acute hepatic prophyrias, namely acute intermittent porphyria (AIP), variegate porphyria (VP), hereditary coproporphyria (HCP) and ALA-dehydrase deficiency. The common feature of all acute hepatic porphyrias is the sudden onset of neurological symptoms. The whole syndrome consists of acute abdominal pain crises with autonomic dysfunction, global or focal central nervous system involvement and a predominantly motor polyneuropathy. Mono- or oligosymptomatic manifestations of acute porphyrias occur and are probably underestimated. The laboratory diagnosis of porphyria depends on the measurement of porphyrin precursors in urine, whereas the measurement of porphyrins in urine and feces is essential for evaluation of the porphyria type. Enzyme measurements are used to identify asymptomatic family members whose quantitative excretions of porphyrins are normal. At present the pathogenesis of neurological manifestations of acute porphyrias remains an unsettled question. The major hypotheses are discussed in this paper. The most important precipitating factor in acute hepatic porphyrias is drug ingestion. As many new drugs have not been in use for sufficiently long periods to assess their porphyrogenic activity, it is safer to avoid drugs in patients with porphyria. The most effective treatment of porphyria attacks is the administration of heme. Among the porphyria patients with epileptic seizures requiring antiepileptic medication, treatment with bromides should be taken into consideration.

Luteinized thecoma with sclerosing peritonitis presenting as an acute abdomen.

The seventh reported case of luteinized thecoma with sclerosing peritonitis is described. Unlike the other reported patients with this condition, the patient presented with a short history of secondary amenorrhea, a subsequent acute abdomen, and an absence of abdominal distention and ascites. The tumor had undergone extensive hemorrhagic necrosis secondary to infarction, and the patient's amenorrhea may have been secondary to the release of steroid hormones from the necrotic cells. The presence of extensive necrosis and a brisk mitotic rate raised the suspicion of a malignant thecoma, but the finding of subserosal fibrosis in the biopsied omental tissue led to the diagnosis of a benign luteinized thecoma with sclerosing peritonitis.
