Ethnicity: post-traumatic stress disorder (PTSD) differences among black, white, and Hispanic veterans who differ in degrees of exposure to combat in Vietnam.

Clinical observations and empirical evidence suggest that, among Vietnam combat veterans, Blacks are more maladjusted than Whites (e.g., Parsons, 1985; Penk et al., 1985). The prediction that minority group status is associated with poorer post-war adjustment and higher rates of PTSD was examined among Vietnam combat veterans who were seeking treatment for addiction disorders. Adjustment scores among groups comparable in combat exposure were found to be similar for both Whites and Hispanics; Blacks, however, score significantly higher on both PTSD symptoms on MMPI scales. These findings indicate that ethnicity contributes importantly to PTSD in selected instances, but that minority group status alone does not account for observed differences. Additional research is indicated in which careful attention is given to the complicating and interacting role of addiction disorders in sampling.

Perioperative nursing research. Part VII: Postoperative care.

The implications for further research will be determined by the changes in surgery and perioperative nursing itself. Things are changing. The development of biliary lithotripsy and more flexible laser angioplasty, to name but two, will reduce the potential for traditional complications of surgery. Bleeding and infection will diminish with less invasive procedures. Similarly, the postoperative course of surgical patients will be assisted by earlier signs detected by pulse oximeters, more accurate assessments of neurological status, and even intraoperative management of acute myocardial infarction. The role of the perioperative nurse will be by no means diminished. In fact, it will expand.

Amino acid pools in the feto-maternal system.

The determinations of the amino acid pools, including tryptophan (by fluorescence spectrometry), in the arterial and venous blood of the mother, the arterial and venous blood of the fetus (cord blood), the amniotic fluid and the placenta was done in eight women at the moment of delivery. Only nine amino acids (asp, try, met, phe, ser, cys, lys, gly, thr) were significantly retained and four (arg, glu, pro and glu-NH2) were significantly released by the fetal tissues. In contrast with this behavior most amino acids were retained by the maternal tissue, try, phe and hist showing the highest retention. When the amino acids are grouped as essential and nonessentials, the maternal tissues retained both categories without apparent discrimination, while the fetal tissues retained essential amino acids preferentially. Our results emphasize the importance of the placenta as the regulating system of the fetal milieu under normal conditions. Thus human fetal blood levels of amino acids are patterned after the placental ones and not after the maternal values obtained at the same time. It is apparent that the placenta seems to function as a nonspecific retention filter for outgoing amino acids, but that its function is selective in respect to the release of amino acids into the fetal circulation.

[Multiple cerebral tuberculomas].

INTRODUCTION: The tuberculosis is a disease that continues being important cause of morbidity and mortality at worldwide level. Its presentation as tuberculomas cerebral manifold at level of the central nervous system is little frequent in immunocompetent patients and can be confused with other etiology. CASE REPORT: An indigenous young man, immunocompetent consulted for history of headache, nausea, vomits, convulsions, double vision and hemiparesia left side, which in the cerebral tomography of revenue was showing injuries compatible with cerebral abscesses; for which he received treatment with antibiotics without improvement for what there takes biopsy of the injuries that reported tuberculomas, specific treatment being initiated later and the primary area being investigated without the same one be detecting. After the first procedural step with evident clinical and radiographic improvement. CONCLUSIONS: The tuberculosis in anyone of their forms of presentation must be included within the diagnosis differential of the patients in our endemic countries for this disease. The clinical and radiological diagnosis of cerebral injuries is difficult and single usually it obtains to the diagnosis during a pathology study that shows tuberculomas with caseosa necrosis, epiteliodes cell and the acid alcohol bacilli resistant.

Treatment of acute leukemia during pregnancy: presentation of nine cases.

The hematologic and obstetric problems of nine pregnant patients with acute leukemia are analyzed. Seven patients received chemotherapy during various trimesters of pregnancy, four during the first 10 weeks, and there was no evidence of congenital malformations in any of their offspring. Six of nine babies are alive and healthy with a normal growth 2 months to 15 years after birth, one child was stillborn, and two children died 21 and 90 days after birth. These results were compared with others in the literature and the conclusions are that pregnancy is not a contraindication for treatment of acute leukemia, that cytotoxic drugs may not cause congenital malformations, and that the management of pregnant patients with acute leukemia should be carefully planned.
