Abstract: Cryosurgery is now a widely accepted modality for the treatment of basal cell carcinomas. This article presents a practical approach to using cryosurgery for this purpose in the dermatologist's office. Understanding the cryobiologic basis of cryosurgery is a prerequisite. Aspects of treatment covered include selection and use of appropriate equipment, indications and contraindications for specific tumors, preoperative preparation, various treatment technics with clinical and instrumental depth-dose monitoring, postoperative care, cure rate, and cosmetic and functional end results. The overall results obtained by cryosurgery compare favorably with those obtained by other modalities. Cryosurgery is the treatment of choice for some basal cell carcinomas and a satisfactory alternate treatment for others.

Abstract: Twenty-three male Black African and 23 male Caucasian subjects, ascertained as sedentary, participated in this study designed to determine whether there were differences in skeletal muscle histochemical and biochemical characteristics between racial groups. Muscle fiber type proportions (I, IIa, and IIb), fiber areas and activities of several enzyme markers of different energy metabolic pathways were determined from a biopsy of the vastus lateralis. Results indicated that Caucasians had a higher percent type I (8%, P less than 0.01) and a lower percent type IIa (6.7%, P less than 0.05) fiber proportions than Africans. No significant differences were observed between the two racial groups in the type IIb fiber proportion or in the three fiber type areas. Enzymes catalyzing reactions in phosphagenic [creatine kinase (CK)] and glycolytic [hexokinase (HK), phosphofructokinase (PFK), and lactate dehydrogenase (LDH)] metabolic pathways had significantly higher activities (about 30-40%) in the Black African group than in the Caucasian group (P less than 0.01). No significant difference was noted in the activities of oxidative enzymes [malate dehydrogenase (MDH), oxoglutarate dehydrogenase (OGDH), and 3-hydroxyacyl-CoA dehydrogenase (HADH)]. Consequently, the PFK/OGDH ratio was significantly elevated in Africans (P less than 0.05). The racial differences observed between Africans and Caucasians in fiber type proportion and enzyme activities of the phosphagenic and glycolytic metabolic pathways may well result from inherited variation. These data suggest that sedentary male Black individuals are, in terms of skeletal muscle characteristics, well endowed for sport events of short duration.

Abstract: The combined experience at two institutions was reviewed to evaluate endometrial biopsy and the prognosis for pregnancies affected by endometrial sampling during the cycle of conception. In the evaluation of 1,084 patients, 1,174 biopsies were performed. Twenty-seven endometrial biopsies were done during the cycle of conception, with spontaneous abortion occurring in six cases (22.2%). Multiple diagnoses were made (including luteal phase defects, endometritis and polyps), and interruption of pregnancy occurred. Several cases illustrate disturbing complications. Methods of minimizing pregnancy interruption and patient discomfort are available.
