The purpose of this paper is to review and update the subject of management of scars and lacerations. The surgion who accepts responsibility for management of soft tissue injuries must be aware of fundamental surgical principles as well as detailed technique. Knowledge of basic anatomy and wound physiology is utilized and applied. ⋯ It is the responsibility of the physician to act within the first few hours and to take the time necessary for accurate approximation and realignment of both soft tissue and bone injuries. Minimal scarring depends on accurate approximation of skin margins without tension. The need for early meticulous repair, so that unsightly scars and disfigurements may be prevented, cannot be overemphasized.

Comparative StudyComparison of free flaps with pedicled flaps for coverage of defects of the leg or foot.
The use of free flaps to repair defects of the leg or foot is a viable alternative to cross-leg flaps because (1) the total time of immobilization and hospitalization is less, (2) the total number of general anesthetics is less, and (3) the morbidity and cost are less. Increased experience will enhance the survival statistics for free flaps, making their use the method of choice for the reconstruction of defects in the distal part of the lower extremity.

Case ReportsHigh-frequency positive-pressure ventilation (HFPPV) in neonates and infants during neuroleptal analgesia and routine plastic surgery, and in postoperative management.
The low pulmonary compliance, the high airway resistance and the "rapid" breathing pattern of neonatal and paediatric patients make it necessary to design special ventilators to match the pulmonary physiology of infants. A ventilator system which also in small children has a negligible compression volume was evaluated in a lung model and during repair of cleft lip and palate in 16 patients under general anaesthesia and in two other infants during other operations. High-frequency positive-pressure ventilation (HFPPV) was given with an insufflation frequency (f) of 60 per min and a relative insufflation time (t%) of 32%. ⋯ Postoperative ventilation required conventional clinical observation and intermittent analyses of blood. HFPPV has been shown to depress, or abolish, spontaneous respiration via reflex mechanisms. In all patients in this investigation respiratory movements were absent at normo- or slight hyperventilation during HFPPV.

The significance of human chorionic gonadotropin in blood serum for the early diagnosis of ectopic pregnancy.
Determination of human chorionic gonadotropin (HCG) values in the serum by the radioimmunoassay technique, was performed in 23 women with suspected ectopic pregnancies. In 16 cases the values of HCG were high and the diagnosis of ectopic pregnancy was verified by laparoscopy and laparotomy. In 7 cases low HCG values were found and ectopic pregnancy was excluded. The detection of HCG in the serum was found to be an excellent tool for the early diagnosis of ectopic pregnancy, thus helping to prevent the dangerous sequelae which follow the late diagnosis of this condition.
