[Predictive factors in the bipolarization of depressive disorders].

Since 1966 maniac-depressive illness has been divided into bipolar disorder (BP) and unipolar disorder (UP). Both groups are still in the process of subtyping (bipolar I,II,III and the tentative subtyping of unipolar group by Winokur). When affective disorder begins with depressive episodes is it possible to predict future mania and anticipate BP diagnosis? Are they variables of good predicting value for bipolarization? The issue is of importance since handicap, evolution, prognosis, treatment are somewhat different for UP and BP. Several studies indicate some possible predictors of bipolarization: pharmacological mania, bipolar familial antecedents, postpartum first episode, hypersomnia and psychomotor retardation, psychotic depression, etc. Special attention is given to switch to mania during antidepressant treatment.

[Endoscopic evaluation of the involvement of the esophagus, stomach and duodenum in human paracoccidioidomycosis].

The upper gastrointestinal tract was investigated endoscopically in 30 patients with paracoccidioidomycosis. Esophagus, stomach and duodenum showed, respectivelly, 40%, 53% and 43% of endoscopic alterations. The histopathological examination of biopsy tissue revealed no specific lesions in esophagus and stomach, but P. brasiliensis was observed in three cases of duodenal lesions: two cases with mucosal diffuse erosions and one case of duodenal polyp. It is concluded that duodenal paracoccidioidomycosis is not rare and could be revealed by endoscopic examination in patients with disseminated disease.

Contraceptive use and the need for family planning in Puerto Rico.

In 1982, 69 percent of Puerto Rican women in union were practicing contraception. Forty-five percent relied on contraceptive sterilization (40 percent, female, and five percent, male), eight percent were using the pill, four percent each, the IUD and the condom, five percent relied on rhythm, and three percent were using other methods. Thus, sterilization is the dominant form of fertility regulation in Puerto Rico, and there is relatively little use of reversible methods for childspacing. Reliance on female sterilization peaks among women in union in the age-group 35-44 (54 percent), whereas pill use is highest among those aged 15-24 (approximately 23 percent). Overall, eight percent of all women aged 15-49 are at risk of unintended pregnancy because they are fecund, sexually active, not pregnant or seeking pregnancy and not using any kind of contraceptive method. However, among women in union, this risk ranges from nine percent among those aged 30-39 to 22 percent among women aged 15-19. Reliance on sterilization rather than reversible methods of contraception is strongly influenced by socio-demographic variables. Women with less than a high school education, the wives of blue-collar workers, women living outside of the major cities and those born in Puerto Rico depend upon sterilization more than do women with a college education, the wives of white-collar employees, women living in cities and those born outside of the country. These findings point to the need for improved availability of reversible family planning services, especially for young women, and those whose childbearing is incomplete.

Acute thrombosis of abdominal aortic aneurysm. An uncommon entity.

Acute thrombosis of an abdominal aneurysm is a catastrophic complication which is little known. It presents as a sudden event, characteristically with lower abdominal pain, signs of profound lower extremity ischemia and pronounced bilateral lower extremity neuromuscular dysfunction. While the mechanism of thrombosis is not understood and is unpredictable, it is certain that the condition is rapidly fatal if uncorrected. The mortality of acute thrombosis is very high, similar to rupture, which is the most common complication of an abdominal aortic aneurysm. Diagnosis is not difficult, and must be followed by prompt surgical restoration of circulation of the lower half of the body, if death is to be prevented. This can be accomplished by aneurysm resection and graft replacement. Retrograde transfemoral thromboembolectomy should not be done. This report describes two successfully operated cases which dramatize the symptomatology of the condition and show the gratifying results of immediate surgical intervention. Only 30 cases (15 fatal) have been reported in the literature.

[Arterial hypertension in adolescents].

The clinical cases of 391 men and 609 women, adolescent all of them, are included in this study. T.A. values were obtained by the Korotkoff method and the lower figures in both measurements analized. The mean value for the men's cases were 112/72/67 and for the women's cases 105/71/67 respectively for K1, K4 and K5. The difference between the sistolic pressures is significant. Taking the mean men and 126/89/86 for the women. Such values might represent the higher values plus two standard derivations it was possible to obtain 139/92/88 for the normal limit. At higher values we found K1 at 1% for men and 10% for women; K4 at 1.2% for men and 5.7% for women; for K5 at 1.1% for men and 2.2% for women. There is a direct relation between obesity and higher figures in T.A. for K1 and K4 in both sexes (p.0.01). The use of too much salt influenced the coming up of K4 to (p.0.01).
