Surgical treatment of obturator nerve palsy resulting from extrapelvic extrusion of cement during total hip arthroplasty.

A female patient was successfully treated surgically for obturator nerve palsy resulting from extrapelvic extrusion of cement during total hip arthroplasty. Obturator nerve palsy developed because of the extrapelvic extrusion of cement medially in the anterior part of the incisura acetabuli in the zone of the extrapelvic exit of the obturator tunnel. Compression of the obturator nerve was confirmed by electromyography. After surgical removal of a piece of cement, 2.5 cm in length, which was done 11 months after total hip arthroplasty, and after 6 months of intensive postoperative rehabilitation, the patient was able to return to everyday activities and normal working habits. After 1 year, clinical and electromyography results were almost completely normal. A review of current knowledge regarding obturator nerve injuries resulting from total hip arthroplasty is presented.

[Clinico-laboratory characteristics of physical urticaria]. / Klinicko-laboratorijske karakteristike fizickih urtikarija.

Physical urticarias represent a specific reaction of the skin, which is characterised by local erythema, edema and pruritus at the site where the physical stimulus has been applied. However, local changes can be associated with various systemic manifestations. Specific cutaneous reactions due to physical factors may be the first manifestation of a systemic and/or infectious disease, which should be taken into account as physical urticarias generally occur in young patients. In view of the above mentioned, as well as unpredictable course of the disease and relatively limited therapeutic effects, the etiology and pathogenesis of the physical urticarias are one of the most interesting fields of investigation in contemporary medicine.

[Laboratory study of patients with endemic nephropathy]. / Prilog laboratorijskim ispitivanjima bolesnika sa endemskom nefropatijom.

The introduction deals with the main characteristics of two representatives of high risk pregnancies: diabetes mellitus and EPH gestoses. Particular interest was shown in risks that may occur in pregnant diabetics, with which they must be acquainted. Some theories are given on the pathogenesis of EPH gestoses. The aim of our investigation was to determine the concentration at which immunoglobulins G, M and A pass in cord blood, amniotic fluid and urine, and whether there is a significant difference between control group and among pregnant diabetics or those with EPH gestoses. The investigation was performed by the nephelometric technique on the Immunochemistry Analyzer. Each group consisted of 20 women, with a total of 60. Immunoglobulins A, M and G were determined in the mothers' sera, cord blood or amniotic fluid. IgG was obtained in urine in measurable concentrations. A significant increase of IgG was found in the urine of pregnant diabetics. IgM was significantly increased in the sera of diabetic mothers. IgA was significantly increased in pregnant diabetics, while both high risk pregnancy groups had an increased IgA in cord blood. The values of IgA in amniotic fluid were decreased in the EPH gestoses group in comparison to the group of diabetics. The authors find these variations interesting and feel they should be followed in other high risk pregnancy groups.
