The importance of atrial fibrillation (AF) as a risk factor (RF) for cerebral infarction (CI) is well-known. It is probably caused by cardiac embolism but other explanations can also justify this association. Our aim was to analyse the features of the patients with CI and AF and sinus rhythm (SR), as well as to form hypotheses as regards the pathogenesis. 250 patients with CI, 204 in RS and 46 in AF (31 non-valvular and 15 associated to a valvular disease) were studied, analysing the prevalence of RF and initial blood tests. The group of patients with valvular AF of probably embolic mechanism had a minor prevalence of RF (hypertension, diabetes, smoking, alcoholism) but higher mortality. The group with non-valvular AF, had a lower RF prevalence compared to the SR group (non-embolic mechanism), without statistical significance and with a similar mortality rate. We concluded that the atherothrombotic mechanism can be the cause of a considerable proportion of CI in patients with non-valvular AF.

Disorders of lipid metabolism, either hyperlipidemia or hypolipidemia, are associated with the formation of corneal opacities. Corneal arcus, the most commonly encountered peripheral corneal opacity, is frequently associated with abnormal serum lipid levels, but may occur without any predisposing factors. Reports also have linked corneal arcus with alcoholism, diabetes mellitus and atherosclerotic heart disease. Unilateral arcus is a rare entity that is associated with carotid artery disease or ocular hypotony. Diffuse corneal opacities associated with hypolipidemic disorders such as LCAT deficiency, fish eye disease and Tangier disease, may be the initial manifestation of these disorders and puts the ophthalmologist in a position to make an early diagnosis. Corneal arcus, along with a central corneal opacity, is seen in Schnyder's crystalline stromal distrophy. The association of the disorder with a dyslipidemia remains controversial. A review of lipid metabolism, corneal arcus and several disorders of lipid metabolism that affect the cornea are presented.

Several autoimmune diseases have been linked to an aberrant expression of major histocompatibility complex (MHC) products Ethanol enhances Class I and Class II products on a variety of cell types, and there is evidence for an autoimmune etiology in numerous pathologies associated with alcoholism. We examined whether ethanol alters the expression of Class I and Class II MHC products on human fetal islet-like cell clusters. Incubation of islet-like clusters for 48 hr in ethanol at a starting concentration of 1.5% increased the percentage of single cells expressing Class I. The percentage of cells expressing Class II did not change, but their relative mean fluorescence increased significantly. These findings suggest that alcohol ingestion could alter MHC expression on pancreatic islet cells in vivo perhaps affecting the development of diabetes in genetically predisposed individuals. These findings also support the hypothesis that the rising incidence of type 1 diabetes seen in areas of the world where the per capita consumption of alcohol is also increasing may be a consequence of the immunological effects of alcohol intake.

Magnesium (Mg) deficiency in man may result in hypocalcemia, impaired PTH secretion, and low serum concentrations of 1,25-dihydroxyvitamin D [1,25-(OH)2D]. To determine whether these changes are due to selective Mg depletion, we studied 26 normal subjects before and after a 3-week low Mg (less than 1 meq/day) diet. This diet induced Mg deficiency, as demonstrated by a fall in pre- to postdiet serum Mg levels from 0.80 +/- 0.01 to 0.61 +/- 0.02 mmol/L (P less than 0.001), an increase in Mg retention from 11 +/- 4% to 62 +/- 4% (P less than 0.001), and a fall in red blood cell free Mg2+ from 205 +/- 10 to 162 +/- 7 microM (P less than 0.001). Serum calcium (Ca) fell significantly from 2.36 +/- 0.02 to 2.31 +/- 0.03 mmol/L (P less than 0.05), and serum 1,25-(OH)2D fell from 55 +/- 4 to 43 +/- 3 pmol/L (P less than 0.05). PTH secretion was impaired, as demonstrated by a fall or no change in serum PTH in 20 of 26 subjects despite a fall in the serum Ca and Mg. In addition, an iv injection of Mg in eight subjects after the diet resulted in a significant rise in PTH from 15 +/- 2 to 19 +/- 2 ng/L (P less than 0.01), whereas a similar injection given to six of the subjects before the diet resulted in a significant fall from 28 +/- 5 to 13 +/- 3 ng/L (P less than 0.001). The fall in serum 1,25-(OH)2D may be due to both the decrease in PTH secretion and a renal resistance to PTH. PTH resistance was suggested, as no increase in serum 1,25-(OH)2D was observed in the six subjects in which the PTH concentration rose by mean of 68% after the diet. Also, the rise in serum 1,25-(OH)2D after a 6-h human PTH-(1-34) infusion was significantly less after Mg deprivation. The results demonstrate that mild Mg depletion can impair mineral homeostasis and may be implicated as risk factor for osteoporosis in disorders such as chronic alcoholism and diabetes mellitus, in which Mg deficiency and osteoporosis are both common.

Hispanics are the fastest growing minority in the United States. Typically, they are divided into five subgroups: Mexican American, Puerto Rican, Cuban American, Central or South American, and "other" Hispanics. Risk factors for morbidity and mortality vary among these subgroups. Use of health care services is affected by perceived health care needs, insurance status, income, culture, and language. Compared with whites, Hispanics are more likely to live in poverty, be unemployed or underemployed, and have little education and no private insurance. Hispanics are at an increased risk for certain medical conditions, including diabetes, hypertension, tuberculosis, human immunodeficiency virus infection, alcoholism, cirrhosis, specific cancers, and violent deaths. Proportionate to their representation in the population, there are few Hispanic health providers, emphasizing the need for all medical personnel to be knowledgeable about Hispanic health care needs.

Nationally, the number of female prison inmates--although small compared with the number of male inmates--is on the upswing. Since correctional facilities are legally mandated under the eighth amendment to provide inmates with their constitutional right to health care, innovative methods of delivering that care will have to be devised within a current system that is neither funded nor prepared to design and dispense such programs. The most frequent medical problems among incarcerated women are drug/alcohol addiction, gynecological diseases, and exacerbation of chronic health problems, particularly hypertension, diabetes and epilepsy. The prison health care system is also being faced with management of an increasing number of pregnant and postpartal inmates. Health needs of this group include basic health care, teaching, counseling and supportive care--services that can be appropriately provided by nurse practitioners and other health care providers.

A retrospective study of 111 patients admitted to the Dermatology department of the Bichat hospital, Paris, between 1981 and 1988 for treatment of erysipelas revealed the following data: 1. Erysipelas was located on the lower limbs in 88.3 p. 100 of the cases and on the face in only 9.8 p. 100. 2. Facilitating and/or aggravating factors were: portal of entry in 75 p. 100 of the cases; impairment of venous and lymphatic circulations (41 p. 100); diabetes mellitus (13.5 p. 100); alcoholism and its socio-economic consequences (29 p. 100); unnecessary prescription of anti-inflammatory agents (11 p. 100). 3. Insufficient consideration was given to the clinical diagnosis: in 7.2 p. 100 of the patients erysipelas was diagnosed either after failure of heparin therapy or because phlebography was normal; some clinical features, notably bullae (30 p. 100) or purpura on the lower limbs (13 p. 100), confused the physicians. Delayed treatment was the main cause of local complications, such as abscess (4 cases) or focal cutaneous necrosis (4 cases). Erysipelas was recurrent in 23.5 p. 100 of the patients. 4. Bacteriological data in this series were insufficient to establish percentages of responsible organisms. However, penicillin G in mean doses of 12 million units per day administered intravenously for 5.5 days, then intramuscularly for 10 days was effective as first-line treatment in 80 p. 100 of the cases. Penicillin therapy may fail in patients with insulin-dependent diabetes or belated treatment with complications. No thromboembolic complication was observed (89 p. 100 of patients with lower limb erysipelas had received anticoagulants). There was only one death due to a severe underlying condition.

Necrotizing fasciitis is an uncommon and severe soft tissue infection characterized by cutaneous gangrene, suppurative fasciitis, and vascular thrombosis. The disease is usually preceded by trauma in patients that have systemic problems, most commonly diabetes and alcoholism. Streptococcus pyogenes and Staphylococcus aureus are the most frequent bacterial etiologies; however, combinations of numerous facultative and anaerobic organisms have also been isolated. Involvement of the face and periocular region is rare. A case is presented here, as well as a review of the clinical features of 15 other patients previously described, in whom eyelid necrosis due to periorbital necrotizing fasciitis developed. Early surgical debridement and drainage of necrotic tissues and appropriate parenteral antibiotics are the mainstay of therapy. The mortality rate in patients with periorbital spread was 12.5%, with the prognosis known to be adversely affected by delay in diagnosis and treatment and/or extension of infection from the face to the neck. Reconstruction of the eyelids with skin grafts was necessary in most cases to avoid such complications as cicatricial lid retraction, lid malpositions, and lagophthalmos.

We report four cases of cutaneous botryomycosis. The predisposing factors included alcoholism, diabetes, and trauma. Clinically, the patients had nodules, suppurative plaques, or ulcers. In two cases, Staphylococcus aureus was cultured. In one case Neisseria species was cultured and in another a coagulase-negative Staphylococcus and Corynebacterium species were the only organism cultured. All patients responded to systemic antibiotic therapy.
