Eosinophilic colitis.

Eosinophilic gastroenteritis, a condition of unknown etiology, has frequently been reported involving the stomach and small bowel. The colon is rarely cited as a site for the condition; however, a review of the literature reveals over 20 cases (including ours). The findings indicate that the colon is now a recognized, but rare, site of involvement and that the condition can be diagnosed via the colonoscope. No clear-cut etiology can be defined, but the presence of allergy (33 percent) and of the herring worm (two cases) is noted.

Whole-body nuclear magnetic resonance imaging: the first report of its use in surgical practice.

This is the first report of whole-body nuclear magnetic resonance (NMR) imaging being of value in clinical surgery. Following aortobifemoral grafting, a 54-year-old man developed a pyrexia and hypotension which did not respond to antibiotic therapy and which was thought to be caused by early graft infection. Whole-body NMR imaging showed the graft and iliac arteries to be normal and an empyema of the gallbladder to be present, NMR imaging is a safe, non-invasive technique for imaging the body in transverse sections and specifically measures the water concentration of tissues, enabling normal and inflamed tissues to be differentiated.

Intravenous radionuclide cystography for the detection of vesicorenal reflux.

Intravenous radionuclide cystography using a single intravenous injection of 99mtechnetium diethylenetriaminepentaacetic acid, provides information on individual kidney function, coarse anatomy and vesicorenal reflux. This study investigates the effectiveness of intravenous radionuclide cystography in detecting reflux. In 58 children intravenous radionuclide cystography detected 53 ureters with reflux compared to 32 detected by voiding cystography. This difference was investigated further with patients in whom other test suggested reflux. While there was no statistically significant difference for patients having pyelonephritis or hydronephrosis, intravenous radionuclide cystography detected significantly more ureters with reflux in patients with abnormal ureteral orifices or infected urine and, therefore, predisposed to reflux. Intravenous radionuclide cystography is a more comprehensive and sensitive test for vesicorenal reflux than voiding cystography.

Intussusception: a study of its surgical management.

Seventy-seven consecutive records of patients with intussusception presenting to the Royal Aberdeen Children's Hospital have been reviewed. The clinical features of the disease, the methods and the results of treatment are described. An attempt has been made to correlate clinical findings with the use, success and safety of operative intervention. Retrospectively, over 40 per cent of the cases possibly justified surgical intervention, but 10 per cent of those operated on had complications. There were no deaths in this series.

"Stasis"--a test for vesico-ureteric orifice competence in children with reflux.

Intravenous radionuclide cystography (IVRNC) with one injection on 99m-Tc-DTPA measures renal function and detects vesico-renal reflux [1, 2, 3]. This paper describes a possible means of detecting incompetent ureteric orifices during IVRNC examinations. In some patients a hold-up of material in the renal areas (stasis) was observed which suddenly cleared at micturition. A prospective study of 58 patients who had IVRNC and cystoscopy within 28 days of each other revealed that 76.3% had anatomically abnormal ureteric orifices on the same side as the stasis. This contrasted with only 12.8% of abnormal uretic orifices found in patients not showing stasis (p less than 0.005). As incompetent ureteric orifices are recognised as the major aetiological factor in vesico-renal reflux [4, 5, 6] this additional information gained at IVRNC could be of clinical use and perhaps avoid some cystoscopies.

The decline in incidence of acute intussusception in childhood in north-east Scotland.

The records have been studied of 77 cases of acute intussusception in children which occurred in Aberdeen City, Aberdeenshire, and Banffshire during the 10 years 1967--76. There has been a decrease in age-specific incidence of about a third since a previous study in the same region was carried out between 1950 and 1959. The decline in rates is greater for rural areas than for Aberdeen City and it is more marked for girls than for boys.

HL-A antigens and thyrotoxicosis.

HL-A phenotypes were determined in 60 patients with primary thyrotoxicosis and in 60 age-sex matched controls living in the same region in order to establish the frequencies of ten HL-A antigens in the two populations. HL-A1 was present in 28 patients and 18 controls (X2 equals 2;86, P greater than 0,05); HL-A13 was present in eigth patients and only one control (X2 equals 4.32, 0.05 greater than P greater than 0.025). These findings suggest that HL-A phenotypes may be of value in studies on the aetiology of primary thyrotoxicosis. The statistical significance of these results is discussed as these findings may be due to chance deviations.
