The diverse potential of thoracoscopic assisted surgery.
Thoracoscopy has been a part of thoracic surgical practice for many years. The introduction of the camera chip and newer instrumentation has awakened a new interest in this technique and led to the development of video-assisted thoracic surgery (VATS). One hundred and seventy consecutive procedures performed on 158 patients are reviewed. Video-assisted techniques have proven useful in a broad spectrum of thoracic surgical procedures both diagnostic (n = 90) and therapeutic (n = 80). Hospital mortality was 1.3%. Conversion to formal thoracotomy was required in 2.5%, and re-exploration for bleeding in 0.6%. The technique was safe and the incidence of complications acceptable. VATS was particularly helpful in diagnosing "indeterminate" pulmonary nodules (sensitivity of 95%), interstitial lung disease (histological diagnosis in all), anterior mediastinal masses and post transplant pneumonitis. VATS may now be the surgical treatment of choice in those with spontaneous pneumothorax, and it also proved useful in a variety of benign disorders. Its role in the management of empyaema is limited with a 57% conversion rate. While pulmonary resections are feasible, its role in the therapeutic management of malignancy is questioned. Further studies are required to define the precise role of VATS in thoracic surgery.

Pregnancy prevention among urban adolescents younger than 15: results of the 'In Your Face' program.
Data from a pregnancy prevention program operating through school-based clinics in four New York City junior high schools suggest that an intensive risk-identification and case-management approach may be effective among very young adolescents. Among students given a referral to a family planning clinic for contraception, the proportion who visited the clinic and obtained a method rose from 11% in the year before the program began to 76% in the program's third year. Pregnancy rates among teenagers younger than 15 decreased by 34% over four years in the program schools. In the fourth year of the program, the pregnancy rate in one school that was unable to continue the program was almost three times the average rate for the other three schools (16.5 pregnancies per 1,000 female students vs. 5.8 per 1,000).
