A technique for skin grafting of postmastectomy defects.

A technique for grafting defects at the site of the mastectomy uses full thickness grafts taken from the lower portion of the abdomen. Primary closure of the donor site can be achieved easily with minimal postoperative discomfort.

[Community laboratories as tools of scientific research on health society in Venezuela].

The School of Dentistry of Zulia University, Maracaibo, Venezuela, set up "community laboratories" to investigate alternative solutions to Venezuelan oral health problems. These academic-administrative units were used to make trial of different arrangements for the provision of dental care in different community situations. The purposes of the community laboratories were to design, develop, and compare comprehensive dental care systems, delegate functions to auxiliary personnel selected in the communities themselves, use simplified equipment, design techniques for reducing costs while maintaining quality, generate a methodology for community motivation, apply preventive techniques on a mass scale, offer the experience so acquired to the public services and to the profession at large, and supply information on the community essential for the design of curricula. The result has been highly encouraging because of the degree of community participation obtained and the salutary effect on student training and attitudes.

Cocaine-codom ingestion. Surgical treatment.

We report one survivor and two deaths from cocaine toxicity. Cocaine, packaged in condoms, was deliberately ingested to avoid detection by customs agents. Because cocaine is a toxic drug, we recommend surgical removal of the ingested packages, as alternative methods of removal are unreliable and potentially dangerous.

A critical appraisal of two common "neonatal" experiment subjects.

A comparative study of 11 physiologic variables in 200 piglets and puppies during the first 7 days of life was done. Seven of 11 physiologic variables significantly changed in the 1st wk of the piglets' life. Five of 11 variables significantly changed in the first week of the puppies' life. Six of 11 variables were significantly different when the newborn piglet was compared to the newborn puppy. The rate and/or direction of 7 of 11 physiologic changes during the first day of life were significantly different when the piglet was compared to the puppy. It was concluded that there are marked physiologic differences between: the newborn piglets and the 7 day old piglet; the newborn puppy and the 7 day old puppy; the newborn piglet and the newborn puppy and the "maturation" rate of the piglet and the puppy.

Profile of pediatric drowning victims in a water-oriented society.

Drowning accounts for 32% of all pediatric accidental deaths in Dade County, Florida. Swimming pools, primarily home pools, are the most common site, 38%; followed by canals, 27%; lakes, ponds and rockpits, 13%; and the ocean and bay, 11%. The majority of drowning victims could not swim and were dead at the scene of the accident. Most pool victims were white, male, and 3 years old. Most victims were thought to be engaged in a non-pool related activity before the accident. Children who drowned in lakes, ponds, and rockpits, canals, and the ocean and bay were usually of school age and unsupervised. Black children had a higher rate of drowning than white children in these sites. Recommendations to prevent drowning: 1) Community education programs; 2) Safety fence around the perimeter of swimming pool; 3) Higher water levels in pools; 4) Investigation of "drown-proofing" instructions for preschool children; 5) Mandatory swimming and water safety instructions in public schools; 6) More supervised public swimming sites.

Colloid versus crystalloid resuscitation in experimental bowel obstruction.

The physiologic effects of fluid resuscitation were studied in 20 piglets with advanced small bowel obstruction. Two solutions were compared: 5% albumin in normal saline and normal saline. Animals resuscitated with albumin-containing solution showed higher serum colloid oncotic pressure, greater loss of peritoneal fluid, lower urine output, and progression of muscular dehydration, when compared to animals resuscitated with similar volumes of normal saline solution.
