[Significance of ultrasound examination in acute abdominal attack of hereditary angioneurotic oedema]

[INTRODUCTION - Hereditary angioneurotic oedema (HANO) is a rare cause of ascites. As acute abdominal attacks of the disease can mimic surgical emergencies, the prompt and accurate diagnosis is essential. This study was undertaken to evaluate the usefulness of abdominal ultrasound examinations in the differential diagnosis. PATIENTS AND METHODS - Seventy patients with HANO were followed up for almost a decade. All patients presenting with an acute oedematous attack underwent abdominal ultrasound, which was then repeated 24 and 48 hours after appropriate therapy. RESULTS - 22 patients with acute oedematous attacks with abdominal complaints severe enough to justify hospital admission occurred in the study population. Abdominal ultrasound performed during the attack showed oedematous thickening of the intestinal wall in 80 per cent of cases and invariably demonstrated the presence of free peritoneal fluid in all patients. Rapid symptomatic relief achieved by treatment was accompanied by the significant regression of ultrasound abnormalities. CONCLUSIONS - Demonstration of transitory ascites by abdominal ultrasound is a clue to the diagnosis of an acute abdominal attack of HANO. The possibility of HANO should always be considered whenever unexplained abdominal pain returns with or without ascites.]

[The value and the risk of X-ray studies in case of infants and children]

WEISENBACH János, TÓTH Áron, KHEZRI Seddiq

[INTRODUCTION - Nowadays the question of roentgenological examination's quantity and indications are getting more and more relevant and debated because of their riskbenefit factors. The authors did not find any publication in the Hungarian literature that carefully studied and measured the amount of radiation doses that are involved in patient's examinations concerning their diagnostic values. PATIENTS AND METHODS - 6094 roentgenological examination's indications and the radiation doses used were studied by the authors at the Department of Paediatrics of Pécs University. The data were analyzed from the examinations of chest, skull and limbs as conventional techniques, urological examinations e.g cystourethrography and intravenous urography, and the CT examinations done during 1999. The results were analysed concerning their effective diagnostic values. Conclusions were based on the results of 6094 examinations. RESULTS - 1591 chest X-ray examinations were performed due to the suspicion of infection. A high proportion of these examinations was negative (345) and 862 showed bronchitis. Similarly in traumatological skull X-ray examinations 225 of 343 were negative. One third of cystourethrographic examinations were also negative. In the case of intravenous urography the number of examinations done was low (30) and the results of those were of great value. CONCLUSION - Based on our results, the chest X-ray examinations with the indication of pneumonia and the traumatological cases of skull and limbs, the patients should be examined more carefully clinically before considering roentgenogical examinations in order to reduce the abundant examples of radiation induction.]

[Craniometry using conventional radiographs]

FEHÉRVÁRI Szabolcs

[I measured the length, width and height of the skull’s hole on standard two-direction radiographs. From these data the volume of the skull's hole can be calculated with high accuracy. I used for calculation the modified formula of sonographic determination of prostate size. Using this measurement method in 1.000 adults (500 male and 500 female) the average skull's hole volume was 1.492 cubic centimetres. In 100 children of 6-7 years (50 boys and 50 girls) average skull's hole volume was 1.423 cubic centimetres.]
