[Diastatic perforations of the colon of neoplastic origin. Apropos of 15 cases].

Typical findings in 15 patients with diastatic perforation of colon due to neoplasm were the preferential site of perforation in cecum and of obstruction in left colon, and the very poor prognosis with postoperative mortality of approximately 50%. The very varied therapeutic attitude is the result of difficulties in deciding which operative procedure is required. When perforation and obstruction are adjacent, a fairly rare observation, radical excision of the segment of intestine involved appears the most suitable operation. When the two lesions are separated then in addition to conservative treatment (suture of perforation and anus bypass or cecostomy alone or combined with colon bypass) an increasing number of authors recommend initial subtotal colectomy.

[Factors in recurrence of perforated duodenal ulcer after simple suture. Therapeutic deductions].

Objective predisposing factors leading to relapse after simple suture for perforated duodenal ulcer were evaluated by a retrospective study of 80 cases. Statistical analysis showed 3 main factors to be involved: age under 45 years, presence of a previous ulcer ano smoking, and these were attributed a coefficient of severity. A simple method will enable a population at high risk of recurrence to be selected, for which immediate radical treatment can be applied when vital risk factors, also analyzed in this study, are lacking.

Xanthogranuloma of the dura in systemic Weber-Christian disease.

A 51-year-old woman who had systemic Weber-Christian disease (WCD) displayed multiple xanthomatous lesions and a large xanthogranuloma of the tentorium cerebelli with signs of brainstem and cerebellar compression. Three other cases of dural xanthomatous lesions associated with systemic WCD have been reported. These dural and leptomeningeal xanthomatous lesions in WCD, a nonsuppurative inflammatory condition, are similar to those of Hand-Schüller-Christian disease, a quasi-neoplastic process.

Isoproterenol induced pancreatic secretion in rats. A comparison with secretin.

The stimulatory effects of isoproterenol and secretin on external pancreatic secretion were compared in the rat. 1. In acute fistula, pylorus ligation, atropine, glucagon did not change either of the stimulated secretions. Propranolol inhibited isoproterenol-induced secretion and did not change secretin induced stimulation. Theophylline alone displayed a large hydrelatic stimulatory effect, without increasing protein excretion; the effect of theophylline was additive with the effects of isoproterenol or secretin but no evidence was found of potentiation or prolongation of action. Isoproterenol did not increase pancreatic blood flow and induced no variations in the plasma levels of immunoreactive secretin. Combining various doses of isoproterenol and secretin did not allow to reach secretory levels greater than the maximal response to secretin. 2. In conscious rats chronic fistulae, isoproterenol and secretin had a distinct effect.

[Lipoma of the colon].

Two cases of submucosal lipoma of the transverse colon are described with their anatomoclinic characteristics and the different aspects of their treatment. These lesions occur with the maximum frequency in the fifth or sixth decades of life and are mostly found in women. 18 per cent of them are located on the transverse colon. In 10 per cent of the cases, the lipomas are multiple. Their clinical symptoms are directly related to their size. Abdominal pains, rectal bleedings and signs of obstruction are the most common symptoms. Thanks to barium enema and endoscopic examination, they are usually diagnosed preoparatively and may be excised through a colotomy in the majority of cases, or by endoscopic removal.
