Cubitus varus--correction by distraction osteogenesis.

Cubitus varus deformity in thirty children was corrected by gradual medial opening wedge osteotomy. The osteotomy was stabilized and distracted by simple external fixator-cum-distractor. The patients of both sexes and age from 6 to 14 years, had varus deformity from 17 degrees to 43 degrees. We achieved good to excellent results in 28 cases as regards to correction of deformity and range of motion at elbow joint. None of the cases had neurological deficit or permanent stiffness. One case had fair result due to under-correction and another case had a poor result as osteotomy united before correction. The main complication faced was superficial pin-site infection particularly in summer season and a in fatty children but was managed by good pinsite dressing and care. The technique has been found to be quite effective, technically simple, cosmetically acceptable and with little, if any, lazy S deformity.

Unicompartmental osteoarthritis of the knee: an innovative osteotomy.

Thirty patients with unicompartmental osteoarthritis of the knee and genu varum deformity ranging from 2 degrees to 15 degrees were treated with high tibial osteotomy by using a medial open wedge, stabilized and distracted with our fixator. Pain relief and correction of deformity were achieved in all except two cases.

Persistence and movement of phorate at high concentrations in soil.

The entrance of a large number of chemicals into the agricultural market has caused concern to both cultivators and scientists because of their effectiveness at the target site, possibility of underground water contamination, and other undesirable effects such as phytotoxicity and effects on nontarget species. The persistence and movement of phorate--a systemic granular insecticide--were studied at high concentrations (4 and 8 kg a.i./ha) in field soil in two seasons, i.e., winter and summer. Periodic sampling for total phorate residues (TPR) at various vertical depths showed that it leached more efficiently at the higher dose (i.e., 8 kg a.i./ha) in both seasons. The horizontal mobility was also higher at this dose. Irrespective of the treatments, TPR leaching was significantly greater in winter with the higher dose, whereas its movement in the horizontal plane was comparatively greater in summer with this dose. The TPR concentration peaks remained stationary at 7.5 cm depth at all the redistribution times until the pesticide was nearly dissipated under both treatments and in both seasons. TPR persistence was higher at the higher dose. Its persistence was comparatively greater in winter than in summer. The present findings show that there seems to be no threat of underground water contamination by this pesticide even at a rate as high as 8 kg a.i./ha.

Evaluation of bacteria and biliary tract diseases.

Bile specimens were taken for culture from 100 patients who had disease originating in the biliary tract. Routine cases of chronic cholecystitis with cholelithiasis were found to have a low incidence of infected bile. An acute process appears to be needed in order to produce infected bile, and an acute obstruction of the bile duct due to gallstones produced infected bile. An effort should be made to select these patients and begin antibiotic therapy as soon as possible.
