[Concepts of the German Society of Tropical Surgery].

The DTC promotes access to surgical care facilities of acceptable medical quality for all people in third world countries. To achieve this goal following concepts and activities are persued: Establishment of a 2-year training programme district surgery Postgraduate surgical training in Germany Workshops and annual scientific meetings Development of adapted surgical technologies Cooperation with national and international organisations Promotion of north-south partnerships between colleagues and hospitals.

Neurological long-term sequelae after spinal anaesthesia in a tropical setting: a case control study.

Spinal anaesthesia (SA) is an important form of anaesthesia in tropical countries. It is considered to have few long-term complications or sequelae, although this hypothesis has not been proven in a rural tropical setting. In a case control study we found SA to he a significant risk factor for lower back pain, reflex abnormalities and muscular atrophy and mild impairment of muscle power in patients examined between 3 months and 4 years after SA.

[Osseous echinococcosis].

Hydatid disease is caused by the parasitic tapeworm Echinococcus. The larval stage of this parasite can thrive in many parts of the body, most frequently in the liver. Primary bone location is very rare, accounting for less than 2% of all hydatid lesions.

Hydatid disease of the pelvis and the femur. A case report.

We report a case of left-sided extended pelvic infestation of hydatid disease. The destruction of the hip joint, os pubis, larger parts of os ileum and the femoral head made pelvic resection and prosthetic replacement necessary. Recurrence of a hydatid cyst 5 years later in the left groin originating in the femur was treated with a second femoral resection and total hip replacement.
