Drinking motives predict alcohol-related problems in college students.

Objective: Drinking motives have frequently been linked to both the quantity of alcohol consumption and the likelihood of negative consequences. For motivational models of drinking to be useful, however, drinking motives must have predictive power independent of other variables typically associated with alcohol-related problems. Thus, this study evaluated the relationship between drinking motives and alcohol-related problems, after first accounting for high-risk alcohol consumption and gender,

Method: Subjects were 139 male and female (61%) college undergraduates, who completed a battery of self-report questionnaires as part of a course requirement.

[Hemispheric functional specialization in motor aphasia. Neurophysiologic findings with computerized electroencephalographic brain mapping during musical and oral sound stimulation. Study of 2 cases].

This study concerns about brain electrical activity during auditory stimulation in 2 aphasic patients, one with classical (left hemisphere lesion) and another with cross aphasia (right hemisphere lesion). Both cases were submitted to dichotic listening test (consonant-vowel-consonant task) and music audition (gregorian chant), during brain mapping examination. We found, in both cases, a great proportion in delta frequency and power in non-lesional hemisphere during dichotic and musical stimulation.

Congenital sensory neuropathy with anhidrosis.

A 6-year-old girl had congenital sensory neuropathy with anhidrosis (CSNA), one of the five variants of a group of very rare genetic disorders of the peripheral nervous system--hereditary sensory neuropathies (HSN). Clinical, laboratory, and physiopathologic aspects are discussed. Dermatologic findings of anhidrosis and self-mutilation suggest the diagnosis.

Thyroid nodular hyperplasia: chromosomal studies in 14 cases.

Cytogenetic study of 14 thyroid nodular hyperplasias revealed a hyperdiploid karyotype in two cases (14%) and a normal chromosomal complement in the remaining cases. Some of the numerical alterations found were identical to the ones considered characteristic of a subset of thyroid adenomas (+5, +7, +9, +12, +14, and +16). Our findings suggest that the cytogenetic events involved in the pathogenesis of thyroid hyperplastic lesions and benign tumors may be closely related, which supports the hypothesis of a biologic "continuum" between these two types of lesions.

Cytogenetic findings in eleven gastric carcinomas.

We describe the results of the cytogenetic study of 10 primary adenocarcinomas of the stomach and one lymph node metastasis of a gastric adenocarcinoma after direct harvesting or short-term in vitro culture. All cases showed a variable number of numerical and/or structural clonal cytogenetic aberrations. Polysomy of chromosomes 2 and 20 were the most common numerical abnormalities.

Loss of Y chromosome in gastric carcinoma. Fact or artifact?

Loss of chromosome Y has been reported in gastric cancer cells together with other chromosomal abnormalities. We noted loss of chromosome Y and near-diploid karyotypes in five cases of gastric adenocarcinoma, but DNA flow cytometry performed on fresh tumor tissue showed aneuploid peaks in four of them. Our findings suggest that loss of the Y chromosome in gastric cancer probably reflects the karyotype of a subpopulation of stromal cells and not a neoplasia-related chromosomal aberration.

[Skin pathology in kidney transplant recipients].

Since 1990, 82 unselected renal allograft recipients were evaluated in order to establish the incidence of cutaneous disorders. This pathology was related to the period of immunosuppression according to time of transplantation: 0-3 months; 3-12 months; 12-36 months and beyond 36 months. Most of them were on triple immunosuppression (cyclosporine A, azathioprine and prednisone)--(51); Twenty-two also associated anti-timocyte globulin five days after transplantation; 7 were on Azathioprine and Prednisone and two of them associated Cyclosporine with Prednisone.

[Headache of cervical origin].

It has been known for many years that headaches can originate from abnormalities in the neck. However, their clinical pictures were never sufficiently systematized, at least not enough to allows for research on their pathogenesis. In 1983 Sjaastad et al.
