Hearing aid dermatitis.

Allergic eczematous contact dermatitis developed in the external auditory canals and external ears of a woman who wore bilateral "in-the-ear" hearing aids. Patch tests demonstrated that methyl methacrylate monomer was the offending chemical. Heat curling the resin increased polymerization and reduced the amount of residual acrylic monomer, thus alleviating the problem.

Etiologic considerations in penoscrotal hypospadias repair.

Superficial location of fivrous bands causing chordee in patients with penoscrotal hypospadias has been demonstrated by microscopic and gross photographs. Our technique to manage this problem is similar to that described by Allen and Spence and by King for distal hypospadias and has been used in 120 patients. The technique involves the repair of the embryologic penile defect by advancing the closure of the urethral groove and transposing the scrotum to its appropriate caudal position. The repair is applicable in patients with failure of fusion rather than failure of the development of the urethral groove as in perineal hypospadias.

[Portal blood flow in minipig and its change by nicotinic acid (author's transl)].

The chronic double catheterisation of portal vein permits estimation of portal flow by dye dilution for example, the withdrawal of blood from the mesenteric vein and proximal portal vein, the injection of drugs into the portal circulation and measurement of portal pressure simultaneously. Beside the well known diminution of portal flow by vasopressin, which is extreme in anaesthetised minipig, there could be shown a remarkable diminution by high intravenous doses of nicotinic acid too without significant changes of systemic blood pressure and heart rat. Nicotinic acid causes also a diminution of pH in portal and venous blood.

[Cystic degeneration of the vessel walls. The differential diagnosis of obliterative angiopathies: (author's transl)].

Cystic degeneration of the vessel wall is a rare disease predominantly localized in the region of the popliteal artery. It appears in the frequent clinical picture of intermittent claudication. Two cases are presented. The etiology of this syndrome is not clear. The appearance of intermittent claudication, preferably in middle-aged men without risk factors is typical for an obliterative angiopathy. Angiophically there are smooth-walled stenoses or occlusions, especially of the popliteal artery, with an otherwise inconspicuous vascular system. The prognosis after surgical treatment by excision or resection is good.
