Evidence for spirochetal origin of Sudeck's atrophy (algodystrophy, reflex sympathetic dystrophy).
Four female patients with Sudeck's atrophy (SA) were evaluated at our department. Sera of all patients were investigated for antibodies against Borrelia burgdorferi. ⋯ In one patient structures identical with B. burgdorferi could be detected on histological sections from the skin of the affected limb. Our data and those of other authors suggest that a spirochetal infection can be regarded as an important etiopathogenetic factor in the development of SA.

Review Case ReportsTransient osteoporosis of the hip in the first trimester of pregnancy. A case report and review of Japanese literature.
A patient with transient osteoporosis of the hip in her first trimester of pregnancy is reported in this study. Rapid symptomatic improvement after artificial abortion was observed. These findings exclude pressure on the obturator nerve, Sudeck's osteodystrophy, venous obstruction, and excessive demand of proteins and calcium in the etiology of this condition. Rather it is here suggested that chemical or hormonal factors related to pregnancy play an important role in the etiology.

Pharmacokinetics of methylmethacrylate monomer during total hip replacement in man.
The concentration of methylmethacrylate monomer (MMA) in the blood stream after implantation of the components of 15 total hip prostheses using bone cement was determined in the pulmonary artery, the radial artery, and the superior vena cava after cement application, and correlated with the observed drop in blood pressure and the increase in the pulmonary arterial pressure. In all samples MMA was found. The values ranged from 0.02 micrograms/ml to 59 micrograms/ml. ⋯ The pulmonary arterial mean pressure increased from 18 to 20 mmHg during the first 10 min. Although in some patients a drop in blood pressure started at the same time as MMA reached maximum values, high concentrations did not result in a greater effect on the circulatory parameters. Statistical analysis by the Spearman test revealed no correlation between MMA concentrations and the decrease in blood pressure or the increase in the pulmonary arterial pressure.

Reduction of shoulder dislocations under interscalene brachial blockade.
Even under short sedation, reduction of shoulder dislocations is often difficult, because of the reflectory contraction of the muscles around the humeroglenoidal joint in response to pain. Administration of interscalene brachial blockade produces analgesia and complete relaxation of the muscles of the shoulder joint. We report on ten consecutive shoulder dislocations which were reduced while the patients were under interscalene brachial blockade. In all cases, reduction was easy and free from complications.

Case ReportsIntraarticular calcaneal fractures in children. Report of two cases and a survey of the literature.
Calcaneal fractures in young children are seen very infrequently. Intraarticular calcaneal fractures in children under the age of ten years make up 8-39% of the calcaneal fractures in that age group, and most often non or only a slight displacement is seen. ⋯ Generally the treatment is conservative and the prognosis very good. Two cases of severely displaced intraarticular calcaneal fractures in children aged six and ten years are presented together with a survey of the literature.
