The effects of HIV/AIDS intervention groups for high-risk women in urban clinics.

OBJECTIVE: This study reports the results of a behavior change intervention offered to women at high risk for human immunodeficiency virus (HIV) infection seen in an urban primary health care clinic. METHODS: Participants were 197 women randomly assigned to either an HIV/acquired immunodeficiency syndrome (AIDS) risk reduction group or a comparison group. Women in the HIV/AIDS intervention group attended five group sessions focusing on risk education; skills training in condom use, sexual assertiveness, problem solving, and risk trigger self-management; and peer support for change efforts. Women in the comparison group attended sessions on health topics unrelated to AIDS. RESULTS: At the 3-month follow-up, women in the HIV/AIDS intervention group had increased in sexual communication and negotiation skills. Unprotected sexual intercourse had declined significantly and condom use had increased from 26% to 56% of all intercourse occasions. Women in the comparison group showed no change. CONCLUSIONS: Socially disadvantaged women can be assisted in reducing their risk of contracting HIV infection. Risk reduction behavior change interventions should be offered routinely in primary health care clinics serving low-income and high-risk patients.

[Mucinous papillary cystadenoma of the pancreas].

The case of a 15-years-old female patient is presented, who referred pain and presence of a mass in the left upper quadrant of the abdomen. Diagnostic imaging showed a 9 cm diameter cystic lesion in the tail of the pancreas which was removed surgically. Histology demonstrated a pancreatic mucinous cystadenoma with borderline biological behaviour. A review of the literature related to cystic neoplasms of the pancreas is realized.

[Vascular compression of the duodenum].

The acute vascular compression of the duodenum is a well-recognized clinical entity, characterized by recurrent vomiting, abdominal distention, weight loss, post prandial distress. The cause of compression is considered to be effect produced as a result of the angle formed by the superior mesenteric vessels and sometimes by one of its first two branches, and vertebrae and paravertebral muscles, when the angle between superior mesenteric vessels and the aorta it's lower than 18 degrees we can saw this syndrome. The duodenojejunostomy is the best treatment, as well as in our patient.

[Oral cholecystosonography. A method to establish the diagnosis of minute cholesterol calculi].

We have studied five patients with clinical symptoms and/or ultrasonography with sludge-like irregularities, but not conclusive for gallstones. The layering of bile and floating of cholesterol gallstones induced manly by administration of oral cholecystographic contrast, has been well demonstrated since 1933. These 5 patients were given doses of iopanoic acid. The day after we performed other ultrasonography--oral cholecystosonography method. With this second cholecystosonography was demonstrated inside the gallbladder en layer or a line of hyperechogenic little floating spots of cholesterol gallstones.
