BACKGROUND Pseudo-allergic reactions caused by aspirin (acetyl salicylic acid; ASA) often resemble immediate-type hypersensitivity reactions consisting of urticaria and angioedema or rhinoconjunctivitis, asthma and nasal polyps. In the last few years, a new in vitro assay based on determination of sulfidoleucotrienes from isolated leucocytes (cellular(More)
BACKGROUND Adverse drug reactions to local anesthetics are frequently reported. However, little is known about the underlying mechanisms. Therefore we investigated 177 patients with a history of 197 events after application of these drugs. METHODS The diagnostic approach included prick and intracutaneous tests, provocative challenge tests with causative(More)
Delayed-type hypersensitivity reactions to subcutaneously (s.c.) injected heparins are common. Since similar reactions usually occur to different heparin preparations, semisynthetic heparinoids might be a therapeutic alternative. We report a patient exhibiting eczematous reactions to heparins as well as heparinoids; delayed-type hypersensitivity was(More)
Two essentially different implant-prosthetic concepts are known for the treatment of edentulous maxillae. One concept propagates a "concentrated" arrangement of four to six implants in the premolar and anterior regions with a fixed cantilever superstructure. An alternative is a "spread-out" implant arrangement of six implants placed in the tuberosity,(More)

After a treatment of 6 months with the antiperspirant Hydonan a contact dermatitis was found in the axillae of a 42 year-old soldier. Hydonan is a combination of 2 emphatic substances: aluminium hydrochloride and propantheline bromide. Aluminium hydrochloride is an adstringence substance, propantheline bromide is a topical active anticholinergic agent. As(More)
Percutaneous retrograde venography was performed in 717 patients with a left-sided idiopathic varicocele. In 674 (94.0%), testicular (internal spermatic) vein insufficiency was proved by contrast medium reflux from the left renal vein into the testicular vein, down to the pampiniform plexus. The different venographic patterns of the testicular veins were(More)
Of 31 boys 10 to 16 years old referred for treatment of a left grade II or III varicocele 28 underwent percutaneous sclerotherapy. Due to anatomical and technical obstacles sclerotherapy was not possible in 3 boys. At follow-up 1 of 16 boys (6.2 per cent) had a mild recurrence detected by Doppler sonography of the spermatic cord. Percutaneous sclerotherapy(More)
The purpose of this study was to investigate the effects of cooling and heating of muscles on parameters of surface EMG (SEMG) under various well defined grades of isometric muscle contraction. In 32 healthy volunteers, aged 20-30 years, turns and amplitude (RMS) analysis was done in SEMG from the hand extensors. Muscle strength was defined by a new(More)
