[Vesico-urethral injuries in patients with pelvic fractures].

Rupture of the bladder and posterior urethra is a serious complication of pelvis fracture. From 1972 to 1984, 61 patients were admitted for genitourinary injuries. We present a review of 5 cases of bladder and urethral posterior injuries associated with pelvic fractures. We assess some current issues in the treatment and diagnosis.

[Congenital fibrosarcoma. Apropos of 2 cases].

Two cases of congenital fibrosarcoma are presented. Both tumors showed histological features of malignancy, but were successful treated with simple resections. Recurrent tumor does not seem to predispose to metastatic disease. Local excision is the initial treatment of choice for lesions occurring in newborns and infants.

Bulk preparation and crystallization of the Escherichia coli elongation factor Tu-Ts complex.

A simple procedure for the preparation of 10-500 mg of the Escherichia coli elongation Tu-Ts complex is described. The protocol is based on the separate purification and quantitation of EF-Tu-GDP and EF-Ts, followed by mixing of equimolar amounts of each protein and removal of the displaced GDP by dialysis. Single crystals grown from the final product have been analyzed by X-ray diffraction techniques. The procedure is also applicable to the bulk preparation and crystallization of the trypsin-modified Tu-Ts complex. Quantitation of the elongation factors by three methods is presented.

Quantitative testing of handgrip strength, myotonia, and fatigue in myotonic dystrophy.

An electrically calibrated, isometric hand dynamometer was used to quantitate maximum voluntary contraction (MVC(, relaxation time and fatigue time (at 50% MVC) in 18 normal and 10 myotonic dystrophy subjects. Precise measurements of MVC and fatigue time were obtained in normals and myotonic dystrophy patients. Relaxation times were markedly prolonged and were quite variable in all patients with myotonic dystrophy in contrast to the highly reproducible times in normals. Neither "warm-up" activity nor acetazolamide treatment altered relaxation time.

[Localized pulmonary interstitial emphysema. Therapeutic management of 3 cases].

Persistent localized interstitial emphysema (PLIE) is a severe complication of assisted ventilation in the neonatal period. From january 1980 to may 1982, 156 cases of IRDS where treated in our Intensive Care Unit. Three of these patients developed this type of emphysema. The initial management was conservative. In two cases, when high ventilatory pressures, and oxygen concentrations were needed to maintain normal blood gases, lobectomy was performed. In both of them mechanical ventilation could be withdrawn shortly after surgery. The third case was managed with conservative medical therapy, and the patient died. In conclusion, when PLIE is diagnosed and does not resolve with medical therapy, the patient needs increasingly higher oxygen concentrations and ventilatory pressures, or mechanical ventilation can not be withdrawn, lobectomy should be performed as long as the process is well localized.
