Evaluation of the frequency of adrenal crises and preventive measures in patients with primary and secondary adrenal insufficiency in Switzerland.

Aims Of The Study: Adrenal insufficiency is a dangerous clinical condition, leading to significant morbidity or mortality in situations with inadequate glucocorticoid replacement treatment. We aimed to assess preventive measures in adrenal insufficiency and the incidence and risk factors of adrenal crisis, as well as to test the patients' knowledge about their disease.

Methods: All patients in May and June 2016 and December 2016 and January 2017 with primary (17.

[False aneurysm of the superior mesenteric artery complicating a pancreatic pseudocyst].

The authors report a case of false aneurysm of the superior mesenteric artery, complicating acute pancreatitis. They insist on the sonographic signs of "the cyst within a cyst"; the presence of a cystic lesion located within a larger mass an US Scanning is highly suggestive of a false aneurysm included in a pseudocyst. They demonstrate the correlation between US Scanning, CT Scan and arteriogram.

[Anuria due to bilateral ureteral blockage by the iliac pedicles (retro-iliac ureters)].

The authors report a case of bilateral retro-iliac ureter with renal failure. The transvascular segments of the ureters were eliminated, and the two ureters were reanastomosed in front of the iliac vessels.

[Lactic acid in the human umbilical cord. Influence of glycolysis in the blood in cord and in cordonal tissue (author's transl)].

The blood staid in human umbilical cord increases his lactate concentration (about + 4 mg/l/mn, in average). It is the fact of an high metabolic activity of foetal erythrocytes for glycolysis, but also of action of cordonal tissue itself. This tissue, after elimination of blood, allows an high concentration of lactate, which increases when cord is kept at room temperature, reaching and rising above 1 or 2 g/kg, after many hours.

Our surgical approach towards the treatment of urethrocele and urethral fistula.

A new technique, described in the text, has been elaborated inspired by that of Monseur (1968) for urethral techniques. It has been performed with success in three paraplegics and in one incomplete tetraparesis. The plastic reconstruction of the diseased part of the urethra after excision of the stenosis and a fistula or diverticula by rotation and fixation to the subcavernal groove creates, in fact, an enlarged neo-urethra rendering the recurrence of the primary lesion practically impossible.

[Lactate dehydrogenase and its isoenzymes in human umbilical cord tissue].

Study on umbilical cord tissue, completely bloodless, for determination of lactate deshydrogenase activity and its distribution among the five iso-enzymes. Comparison with placenta, amniotic fluid, serums of blood of cord and of mother. Cord tissue is very active (about 360 muKatals, in average) and it is a similar result in placenta (as it is possibly bloodless).

[Cholinesterases and arylesterase in the umbilical cord, the placenta, and the amniotic membrane, in the female at term].

Cholinesterasic activity of umbilical cord (tissue), completely bloodless, is exclusively due to pseudocholinesterase. Cholinesterase is more active in placenta than in cord; it is an acetylcholinesterase at 80 per cent. Both forms coexist, about equally, in amniotic membrane.

[Cholinesterases (acetyl and pseudocholinesterase) in human amniotic fluid].

Study on 41 cases. The cholinesterasic activity of human amniotic fluid, free from blood, is very weak, in average 0,10 microkatal, approximatively 300 times weaker than mother's serum. In this "total cholinesterase", we find a large amount (about 40%) of acetylcholinesterase.

[Amniotic fluid arginase in women at term].

Study on 34 cases. A considerable arginasic activity is observed in amniotic fluid in women at the end of pregnancy. This activity is weak, but increased by Mn2+ (about 5 to 8 times).
