The prognostic significance of virus-associated changes in grade 1 cervical intra-epithelial neoplasia.
Virus-associated changes of the cervix uteri were assessed in patients treated for grade 1 cervical intra-epithelial neoplasia (CIN). Of 106 patients evaluated, 67 (63%) had virus-associated changes. The patients were treated without regard to the presence/absence of virus-associated changes. In 26 patients the treatment was unsuccessful (persistence, recurrence, or progression of the neoplasia). The frequency of treatment failure was 33% in patients with, and 10% in patients without virus-associated changes (p less than 0.025). It is recommended that patients with CIN 1 and virus-associated changes should, after initial treatment, be followed-up with increased attention.
Ureteric obstruction as a complication to the appendicular abscess. Case report.
In three patients an appendicular abscess caused right-sided ureteric obstruction, and temporary decompression of the upper urinary tract was necessary in two. All recovered completely following combined appendectomy and drainage of the abscess. Since early treatment is essential, the possibility of obstructive uropathy must be kept in mind in the treatment of the appendiceal abscess, especially when nonoperative management is favored.
Whole gut lavage for colonoscopy. A comparison between preparation at home or at the hospital.
The clinical efficiency and patient acceptability of peroral colonic lavage with a 3 liters balanced electrolyte solution (BES), when performed either at the hospital on the day of colonoscopy or during the preceding evening in the patient's home, was evaluated in 62 consecutive outpatients. No significant difference was found between adequacy of bowel preparation, when the lavage was performed in the patient's home or at the hospital. The bowel preparation was found to be satisfactory in 61% and 77% of the patients. The percentage of sufficient preparation was 60% of the patients, who were not able to drink 3 litres of BES within the 2-hours period. This study demonstrated that colonic lavage with BES could be performed equally well at home the day before colonoscopy as at the hospital on the day of colonoscopy. The relatively low rate of sufficient preparation was related to the fixed and small volume of BES ingested. To improve the adequacy of bowel preparation a graded intake of BES is suggested.

Carcinoid of Meckel's diverticulum. Report of two cases with perforation, in one with concomitant foreign body.
Histologic examination of two perforated Meckel's diverticula revealed carcinoid tumours. One of the diverticula also contained a foreign body. All resected diverticula should be histologically examined, as ileal carcinoids often are multiple, and even small tumours have metastasization potentiality.
