Acute carpal tunnel syndrome as a complication of oral anticoagulant therapy.

Acute carpal tunnel syndrome is well recognized in patients with haemophilia and conservative management with factor replacement and temporary splinting is recommended. There have, however, been very few reported cases of acute carpal tunnel syndrome as a complication of oral anticoagulant therapy. We describe such a case in a patient on long-term warfarin anticoagulation, drawing attention to particular features of the history and clinical findings. In contrast to previous reports, we recommend prompt decompression under local anaesthesia and continuation of the anticoagulant therapy.

Unilateral lower limb hypoplasia in arterial fibromuscular dysplasia.

Hypoplasia or hyperplasia of limbs can be unilateral or bilateral and can involve the upper or lower extremities in any combination. The etiology is varied, and the presentation, clinical features, and investigative pathway differ to some extent among patients. Reported here is a child, referred for limb lengthening, with claudicating unilateral leg pain and unilateral hypoplasia of the same limb. Investigations revealed multiple arterial stenoses consistent with fibromuscular dysplasia. In such cases, early diagnosis and intervention with angioplasty may enhance subsequent growth of the limb, thus avoiding the need for limb lengthening procedures.

A comparative study of the disease in cattle caused by Theileria parva or T. lawrencei: II. Hematology, clinical chemistry, coagulation studies and complement.

Theileria lawrencei tick-derived stabilate infection of 8 cattle resulted in the development of panleukopenia and hypoproteinemia. In addition to these changes, T. parva infection caused mild normocytic, normochromic, non-responsive anemia at either of two dose rates. Disseminated intravascular coagulation, as indicate by positive protamine paracoagulation tests, prolonged prothrombin and partial thromboplastin times, and thrombocytopenia, developed in cattle infected with either of the Theileria spp., and was probably an important intermediary mechanism leading to death. Infection of calves with a high dose of T. parva stabilate resulted in more rapid onset of clinico-pathologic changes than did the low dose infection. Theileria lawrencei infection produced a severe, acute syndrome, the clinico-pathologic alterations of which varied in time of onset and severity between those of the T. parva high dose and low dose groups.

The demonstration of maedi/visna virus in sheep in Great Britain.

A virus indistinguishable from that causing maedi/visna has been isolated from a sheep flock in Great Britain. The virus was identified in cell cultures using immunofluorescent and electron microscopical techniques. The complement fixation test and the agar gel immunodiffusion test were used to assess the proportion of serological reactors within the flock. There has been no evidence of clinical disease in the flock into which foreign imports were introduced in the years prior to 1976.

Tibial tuberosity excision for symptomatic Osgood-Schlatter disease.

A modified Ferciot procedure was used to excise the tibial tubercle in patients with persistently symptomatic Osgood-Schlatter disease. Forty-two knees in 35 patients were reviewed at a mean follow-up of 5 years to assess outcome. The results revealed relief of pain in 95% of patients and reduction of prominence in 85.5% with minimal complication, in particular no evidence of genu recurvatum. The pathogenesis of the condition is outlined, and some of the theories and treatment modalities discussed. Tibial tubercle excision is recommended as the treatment of choice in those few cases that fail with conservative treatment.

Comparative and multilaboratory studies of two immunodiffusion method enrichment protocols and the AOAC/Bacteriological Analytical Manual culture method for detection of Salmonella in all foods.

The single enrichment immunodiffusion (1-step), the preenrichment and selective enrichment immunodiffusion (2-step), and the AOAC/Bacteriological Analytical Manual culture methods for Salmonella were evaluated for equivalence in 2 separate studies, a comparative evaluation and a multilaboratory dilution study. In the comparative study, all 3 methods were performed on 10 food types. For 550 samples, analyses resulted in 99.3 and 99.6% agreement between the culture method and the 1-step and 2-step methods, respectively. False negative rates were 0.9 and 0.3% for 1-step and culture, and 0.0% and 0.6% for the 2-step and culture, respectively. Subsequently, 6 food types were included in a multilaboratory dilution-to-extinction study. A sequential dilution series of Salmonella in foods was analyzed by the 3 methods to determine their lower limits of detection for Salmonella. A total of 1185 samples analyzed resulted in 98.9% agreement between 1-step and culture, and 99.7% agreement between 2-step and culture. False negative rates were 1.8 and 0.1% for 1-step and culture, and 0.4 and 0.1% for 2-step and culture, respectively. During these evaluations, 1735 samples and controls representing 10 different naturally contaminated and inoculated foods were tested. The data indicate statistical equivalence of all 3 methods when analyzing all food types.
