[Changes in emergency visits of patients infected by human immunodeficiency virus since the widespread use of protease inhibitors].

OBJECTIVE: To evaluate the changes in the urgent visits made by HIV+ patients after generalisation of the protease inhibitors. PATIENTS AND METHODS: Comparison on the visits made during a period prior to and after use of protease inhibitor. RESULTS: After the generalisation of the protease inhibitors the visits rate decreased, the motives for consulting with the physician and complementary examinations changed, invasive therapeutic procedures, admissions from urgencies and death rates decreased. CONCLUSIONS: The protease inhibitors have changed the urgent visits profile of HIV+ patients.

Effect of temperature on the lactose hydrolytic capacity of a lactase derived from Kluyveromyces lactis.

In vitro studies of lactose hydrolysis in milk with 20-125 neutral lactase units (NLUs) carried out at 38.0 degrees C for 15 min with a beta-galactosidase derived from Kluyveromyces lactis (Lactaid, Lactaid Inc, Pleasantville, NJ) resulted in 85-95% of the hydrolysis observed with standard incubation conditions (24 h at 4-5 degrees C with 1000 NLU/L). Thirty-three lactose-maldigesting Guatemalan subjects, 16 children and 17 adults, were challenged with oral doses of lactose in milk (children aged less than 12 mo, 2 g/kg body wt; children aged 12-24 mo, 15 g/kg body wt; older children and adults, 18 g/kg body wt) preincubated for 20 min at 38 +/- 0.5 degrees C with 50-125 NLU Lactaid. Under these conditions the subjects consumed milk without presenting any signs of intolerance. Furthermore, their breath-hydrogen excretion showed a 91-93% reduction when compared with a similar load of milk containing nonhydrolyzed lactose.

Family Life Education in the English-speaking Caribbean.

Unique experience has accumulated in the English-speaking Caribbean in the field of family life education for youth. Although birth rates are relatively low, the increase in adolescent pregnancy and births is becoming more visible. Mother-centered homes are frequent, and support from the father is often lacking. A series of family life education (FLE) programs funded by the United National Fund for Population Activities is aimed at providing help to the various groups in the Caribbean in an acceptable and non-threatening manner. These out-of-school FLE techniques include several approaches: integration of the proposed program into an already established place (a factory, youth center, or community center); education in human growth, food and nutrition, environmental health, mental health, safety and first-aid, dental health and human relations, including human sexuality, rights and responsibilities, and decision making; and the use of specially trained personnel who understand the conditions of the particular community. In some countries adolescent pregnancy is viewed as a problem. In others it may not be so considered. It is vital for the staff and community leaders to review proposals for the FLE program and bring into the centers all subjects that are free of controversy. Family planning, contraceptive delivery and even human sexuality may be acceptable subjects in some quarters, and not in others. Efforts must be continued to find innovative approaches to assure that the benefits of these learning activities continue to be provided, and expanded in response to growing acceptance.

[Turner's syndrome and heart surgery. Presentation of 3 clinical cases].

Three patients with Turner's Syndrome are shown; one associated with coarctation of the aorta, other with patent ductus arteriosus and the last one with congenital valvular aortic stenosis. The cytogenetic and clinical picture of the disease are reviewed, also its association with some cardiovascular malformations. The results of the surgical treatment of the congenital heart disease are reported. The difficulties to establish the operatory indication are described and besides the technical problems that occur frequently in these patients.

[Surgical correction of acute congenital cardiopathies in the newborn infant].

The experience of the Cardiac Surgery Service at the Hospital del Niño IMAN with the deep hypothermia method and hemodynamic arrest is shown in 30 infants with severe congenital cardiac malformations. The procedures followed before and during the operation are carefully described in their three aspects; anesthesia, extracorporeal circulation and surgery, including postoperative care. Ventilatory assistance is stressed. Results are analyzed considering postoperative evolution; stress is made on the causes of morbidity and mortality. Considering the results of this and other similar reports, we believe that the deep hypothermia method and heart arrest in treating severe cardiac malformations in infants are of outstanding importance since they have significantly improved results in these problems.

Anesthesia, General↗

[Surgical treatment of pulmonary valve stenosis].

"Open" pulmonary valvotomy with vena cava occlusión and normothermia was first performed by Varco in 1950, but the procedure was abandoned with the arrival of extracorporeal circulation. This paper compares two groups of patients who were operated with Varco's procedure and extracorporeal circulation. Similar data of both procedures are analyzed as well as their advantages and disadvantages. It is concluded that Varco's proceduce is useful in well selected patients with no associated anomalies in which the possibility of complications of extracorporeal circulation is avoided. Also, equipment, personnel, surgical time and stay in the Intensive Care Unit and in the hospital are reduced, saving cost as much as 50%.
