Assessing alcoholism as a risk factor for acquired immunodeficiency syndrome (AIDS).

Acquired Immunodeficiency Syndrome (AIDS) is characterized by a range of risk factors that determine susceptibility to HIV and the clinical expression of the disease. These include sexual practices, intravenous drug use, and blood exchange. Appropriate preventive measures have been formulated for these risk factors.

Primary spinal epidural Burkitt's lymphoma.

Three Japanese children suffered from symptoms of spinal cord compression, and myelography demonstrated extradural masses compressing the spinal cord at different levels. Decompressive laminectomy revealed epidural tumors which were resected as completely as possible. Histologic pictures of the tumors showed Burkitt's lymphoma, and the diagnosis of primary epidural Burkitt's lymphoma with clinical stage A was made in each case after postoperative examination.

Ultrastructural study of initial calcification in the rat subcutaneous tissues elicited by a root canal filling material.

The ultrastructural aspects of initial calcification in the rat subcutaneous tissues elicited by the root canal filling material Vitapex, made up of calcium hydroxide and iodoform with the addition of silicone oil, were studied by means of electron microscopic and cytochemical techniques. The embedded paste caused heterotopic calcifications. These were divided into two types: dystrophic calcification and matrix vesicle calcification which resembled that of bone tissue.

A case of pericardial hemangioma with consumption coagulopathy cured by radiotherapy.

An infantile case of pericardial hemangioma with large pericardial effusion and consumption coagulopathy is described. This is the first reported case of pericardial hemangioma cured by radiotherapy.

Ultrastructural study of calcinosis universalis with dermatomyositis.

Calcinosis universalis associated with dermatomyositis occurred in a 58-year-old woman. Tissues removed from the sublingual region in the patient were studied by ordinary microscopy, electron microscopy, and an electron-microanalytic method. The calcified materials were distributed on collagen fibers and seemed to have a relationship with foci of fibrinoid degeneration.

Neuroepidemiology of acquired immune deficiency syndrome.

Neuroepidemiology is that branch of chronic disease epidemiology dealing with disorders that affect the nervous system. The potential for neurological involvement in the diagnosis and pathogenesis of Acquired Immune Deficiency Syndrome (AIDS) has recently been noted. The following review outlines the spectrum of neurological conditions seen in AIDS patients to date.

Mode of interaction of beta-hydroxy-beta-methylglutaryl coenzyme A reductase with strong binding inhibitors: compactin and related compounds.

The sodium salts of compactin (1) and trans-6-[2-(2,4- dichloro-6-hydroxyphenyl)ethyl]-3,4,5,6-tetrahydro-4-hydroxy-2H-pyran- 2-one (3) are inhibitors of yeast beta-hydroxy-beta-methylglutaryl coenzyme A (HMG-CoA) reductase. The dissociation constants are 0.24 X 10(-9) and 0.

Anxiety and dental caries.

It is accepted that emotional stress causes various kinds of degenerative physiological changes. We have assumed that it is important to study the relationship between anxiety and dental caries. Anxiety and personality of children were investigated and oral examinations and questionnaires about their life style were performed.
