Sciatica in the female patient: anatomical considerations, aetiology and review of the literature.

The principal author was confronted few years ago with the case of a 38-year-old woman with a 5-month history of ill-defined L5 sciatic pain that was referred to an orthopaedic department for investigation and eventual surgical treatment for what was suspected to be herniated disc-related sciatica. Removal of her enlarged uterus found unexpectedly close to the sacroiliac joint upon lumbar MRI abolished her symptoms. Review of the literature showed that the lumbosacral trunk is vulnerable to pressure from any abdominal mass originating from the uterus and the ovaries.

The cervical spine in calcium pyrophosphate dihydrate deposition disease. A prevalent case-control study.

Objective: To test the hypothesis that calcium pyrophosphate dihydrate (CPPD) deposition disease is a risk factor for neck pain.

Methods: A prevalent case-control study was conducted to assess cervical calcifications and neck pain between patients with and without known peripheral CPPD deposition disease. CPPD cases were included if diagnosed with CPPD deposition disease of peripheral joints, and excluded if their chief complaint was neck pain.

Vaccination against Leishmania major in a CBA mouse model of infection: role of adjuvants and mechanism of protection.

Gp63 is a major surface protein of Leishmania promastigotes. Its protective efficacy has been tested in several experimental models using different mouse strains, gp63 forms, adjuvants and routes of immunization, giving rise to conflicting results. This investigation was designed to determine whether these discrepancies could be ascribed to differing experimental procedures, and to compare gp63-induced protection with that achieved using live promastigotes.

Vaccine development against cutaneous leishmaniasis. Subcutaneous administration of radioattenuated parasites protects CBA mice against virulent Leishmania major challenge.

Experiments described in this paper were aimed at determining whether subcutaneous inoculation of live, avirulent Leishmania major would protect mice against infection by the virulent parasite. To this effect, promastigotes or amastigotes of a highly virulent strain of L. major (MRHO/IR/76), used in human trials of leishmanization, and which induces non-healing skin lesions in both CBA and BALB/c mice, were rendered non-pathogenic by gamma irradiation.
