Trans-scaphoid perilunate dislocation with fractured carpal bones in a child.

Transcarpal fractures and dislocations in children are rarely reported in the orthopedics literature. This is a report of a 10-year-old boy who sustained a trans-scaphoid perilunate dislocation with fractures across the carpal structure: these included injuries to the scaphoid, capitate and triquetrum bones. Treatment consisted in a closed reduction for the dislocation and using the dorsal approach of an open reduction with internal fixation of the fractures. The injury healed well with a full return of good wrist function. This unusual pattern of injury is described so that it may be more readily appreciated in the future.

A case of bronchiolitis obliterans organizing pneumonia with renal dysfunction after renal transplantation.

A 35-year-old male renal transplant patient was admitted with 3-week history of cough and myalgia after a 3-month post-transplantation. The patient's posttransplant course was uncomplicated and had no rejection. But on admission, the serum creatinine was 3.0 mg/dl and high-resolution computed tomography (HRCT) showed bilateral patchy densities and peripheral consolidations. Renal biopsy revealed mononuclear cell infiltration and non-specific tubular injury without evidence of rejection. An open lung biopsy was performed which showed multiple fibroblast plugs filling airspaces that were typical pathologic features of bronchiolitis obliterans with organizing pneumonia (BOOP). After prednisone therapy, the patient's pulmonary symptoms and radiographic findings rapidly recovered and serum creatinine also decreased from 3.0 to 2.1 mg/dl. Although the cause of renal dysfunction was not elucidated, we herein report a rare case of BOOP with renal dysfunction after renal transplantation.

The comparative selection between spiral wound and disc tube membranes to treat steel industry wastewater.

To select the most suitable membrane process to treat the final effluent discharged from the S wastewater treatment facility at P Steel Works, the effluent was passed through two types of membrane (spiral wound and disc tube) in a pilot-scale study. The permeate flux and regeneration of each membrane were comparatively observed and the removal efficiency of contaminants determined. The experimental results from employing the disc tube membrane revealed that the fouling was comparably limited by operating the plant at 34 bar recovery and was highly sustained at permeate flux of 75% which equals to 32.9 l/hr.m2. In contrast, the fouling was significantly greater when applying the spiral would membrane with the recovery correspondingly diminished at 72%. The disc-tube membrane was chosen to treat the effluent to be recycled for process water as the water quality satisfied the industry water standards.

Comparative study of shortwave heating patterns in phantoms with polyethylene and silk partitions.

Specific absorption rate (SAR) and effective depths of heating patterns induced by a shortwave, pancake diathermy applicator in fat-muscle phantom are measured. Midplane partitions of polyethylene and silk screen with and without contact chemicals are used. Thermographically obtained SAR data show nearly the same value for silk-screen partitions with and without contact chemicals and slightly lower values with polyethylene partitions, provided that the partition midplanes are tightly pressed against each other. Thermometry data indicate that for low-power exposures the major error in thermographic measurements obtained after termination of heating is due to thermal diffusion and not evaporative cooling in the opened midplane of the phantom.
