Effect of functional bracing, quadriceps and hamstrings on anterior tibial translation in anterior cruciate ligament insufficiency: a preliminary study.

Anterior tibial translation was measured in six patients with anterior cruciate ligament insufficiency. The tests were done in 15, 45, and 90 degrees of knee flexion, partly with activated quadriceps or hamstrings, and partly with subjects wearing a 4-point functional DonJoy brace. The translation was evaluated with a computerized electrogoniometer (Acufex KSS). The anterior tibial translation was significantly reduced by use of the hamstrings in all three degrees of knee flexion. The effect of the 4-point brace was only significant in 15 and 45 degrees of flexion. The quadriceps did not reduce the anterior tibial translation.

Early detection of circulating anodic antigen (CAA) in a case of acute schistosomiasis mansoni with Katayama fever.

A 34-year-old male developed acute Katayama fever with fever, diarrhoea, joint pains, headache, urticarial rash and eosinophilia 18 days after falling into and spending 15 min in the water during water-skiing in the outlet of the Volta river. Low anti-schistosomal antibody titres were found by the immunofluorescence assay after 4 weeks, and the first Schistosoma mansoni eggs were found in faeces after 6 weeks. Both symptoms and eosinophilia increased the first days after treatment with oxamniquine, after which he improved gradually. Examination of frozen sera by the newly developed Magnetic Beads Antigen Capture-EIA (MBAC-EIA) later demonstrated a peak in schistosomal circulating anodic antigen (CAA) levels of diagnostic significance already 4 weeks after he was infected.

Comparison of induction with and first hour of recovery from brief propofol and methohexital anesthesia.

Anesthesia and recovery during the first hour after propofol and methohexital anesthesia for termination of pregnancy, lasting about 12 min, were compared, the latter in a double-blind manner by means of psychomotor tests (coin counting and continuous auditory reaction time). Muscle movements and hiccups were seen significantly more frequently during methohexital inductions. No differences were seen regarding pain at the site of injection or apnea between the groups. At 15 min after the last dose of anesthetic, recovery after methohexital was ahead of that after propofol, but after 1 h, psychomotor performance was better in the propofol group. Side-effects during recovery were few, and incidences did not differ significantly. Although the difference in reaction time test was significant, it was hardly large enough to be of any clinical importance. Both drugs are useful for brief outpatient anesthesia, but smoother induction gives propofol an edge over methohexital.

[20 years experience with chlorprothixene (author's transl)].

Chlorprothixene was the first neuroleptic of the thioxanthene group and was marketed in 1959 under the trade names of Taractan and Truxal. Since then 20 years have passed and the authors were of the opinion that it would be opportune to study the literature published during these 20 years. They perused 801 publications, hereof 542 clinical works. Of these clinical works 109 were suited for statistical analysis. They represented 7109 patients. The other publications comprise 4378 patients which means that all the literature studied consists of a total of 11487 patients. The chlorprothixene proved to be a broad-spectrum neuroleptic with good therapeutic effects. Side effects, especially the extrapyramidal symptoms, appeared only seldom. Among the 11487 patients only 1.02% showed extrapyramidal symptoms and of these only 0.05% had tardive dyskinesias. Sme evidence seems to exist that these are schizophrenic patients showing extrapyramidal symptoms, without having received neuroleptics. It is the authors' opinion that chlorprothixene is still a neuroleptic of topical interest.
