Urinary excretion of 5-S-cysteinyldopa is enhanced by PUVA and is independent of skin type.

Urinary excretion of 5-S-cysteinyldopa (5-S-CD) was followed in 20 patients receiving PUVA therapy. Large increases were observed after PUVA treatment, more predominant in males and unrelated to skin types. Relative increases rather than absolute values paralleled cutaneous reactions.

Trichinella spiralis in rats: in vivo effects of the bile and in vitro action of secretory IgA from bile.

The biliary secretion of rats is diverted from the choledoch duct to the bladder. These rats are resuscitated by sub-cutaneous injections of a salt solution and then infected with Trichinella spiralis larvae. It is shown that the number of adult worms is increased (+ 66%); as is the female larvae production (+ 51%); the females' length is also increased (+ 25%). 40 days after the infection the number of muscular larvae is considerably increased (+ 79%) in comparison with control rats. Secretory IgA (SIgA) from rats bile were tested in vitro on the female production of larvae. This larvae production was more inhibited (59%) by immune SIgA than by control SIgA (25%).

[Use of radiology in the diagnosis of posttraumatic otoliquorrhea. A report on 33 operated cases (author's transl)]. / Apport de la radiologie dans le diagnostic des otoliquorrhées d'origine post-traumatique. A propos de 33 cas opérés.

The association of standard radiography and tomography can enable the origin of the fistula to be established with reasonable precision : complementary contrast cisternography should permit direct localization. Treatment is essentially the concern of the E.N.T. surgeon, but the problem cannot be resolved without a perfect understanding between the neurosurgeon, surgeon, E.N.T. specialist, and the radiologist.
