A 71-year-old man was admitted to the Wake Forest University/Baptist Hospital Medical Center on February 1, 1989, with pharyngitis and a cutaneous eruption that began that day. The past history was significant for a diagnosis of chronic lymphocytic leukemia (CLL) made in 1984, and for longstanding hypertension, severe coronary artery disease, and prostatic hypertrophy. The patient had required no therapy for his CLL until August, 1988, when he developed hemolytic anemia and was treated with oral chlorambucil, 4 mg/day, and a tapering course of prednisone. By December, 1988, the prednisone therapy had been discontinued, but the patient required hospital admission for pneumococcal pneumonia, which responded well to intravenous antibiotic therapy. One day prior to the current admission the patient complained of persistent fevers, sore throat, productive cough, and headache. He noted a new cutaneous eruption on the day of admission in February, 1989. The past history was positive for occasional herpes stomatitis. The patient did not know if he had previously been infected with varicella. Skin examination revealed multiple (greater than 20), single, and grouped vesicles in a generalized distribution involving the bilateral trunk, head, neck, arms, and legs. The heaviest involvement was on the right posterior auricular area and on the neck. A Tzanck preparation obtained from an early lesion was positive for multinucleated giant cells. Viral culture was negative at 24 hours and at 1 week. A skin biopsy of an early vesicular lesion was performed and revealed intraepidermal vesicles with acantholysis and giant cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Blacks, Hispanics, and whites were interviewed in a door-to-door survey assessing personal concern about AIDS relative to other health threats and willingness to attend in-home AIDS education programs. The survey consisted of three parts: (1) an open-ended inquiry regarding which health problems individuals wanted to learn more about, (2) ratings of concern about AIDS and nine other common health threats, and (3) assessment of willingness to participate in future neighborhood-based AIDS education programs. Usable data were obtained from 453 respondents. Sixty-seven health threats were mentioned in response to the open-ended inquiry; AIDS was mentioned by 50.7%, followed by cancer (19.9%). AIDS was mentioned more frequently by blacks (63.9%) than by Hispanics (42.5%) or whites (45.7%), X2(3) = 32.07, p less than .002. Participants also reported higher levels of concern about AIDS than any other health problem with the exception of cancer. Concern about AIDS was greater among blacks (M = 2.68) than among Hispanics (M = 2.33) or whites (M = 2.36), F(2,351) = 5.06, p less than .01. Differences as a function of ethnicity, gender, and/or age were observed with respect to concern about heart disease, high blood pressure, diabetes, drug abuse, colds and flu, and herpes. In general, blacks and Hispanics expressed more interest in participating in AIDS education programs than did whites. Concern about AIDS and other health threats was not consistently related to either disease prevalence or severity.

This article reports the first successful human orthotopic liver transplantation performed in Mexico. The recipient was a 41 year old white male, with a history of essential hypertension and hepatitis in 1975. The diagnosis of postnecrotic cirrhosis was made in 1985 by liver biopsy. The HBsAg was negative and the functional reserve of the liver was limited (Stage "C" of the Child-Pugh classification). A liver graft was obtained through the National Cadaver Organ Transplant Program on May 2, 1988 and an orthotopic liver transplantation was performed without incidents, using the portosystemic veno-venous bypass. Inmunosuppression was carried out with triple drug therapy, cyclosporine, azathioprine, and prednisone. His postoperative course was characterized by idiopathic cholestasis, one episode of acute rejerction, arterial hypertension, renal dysfunction, esophageal herpes and inguinal lymphocele, all of which resolved. Currently the patient is alive 22 months postransplantation with normal liver function and adequate quality of life.

To determine the importance of intracranial hypertension in central nervous system acute infections, we studied intracranial pressure (ICP) in 27 patients, aged 45 days to 13 years. Fourteen had meningitis and 13 had encephalitis; all were in deep coma with a Glasgow Coma Scale 7 or less. Intracranial hypertension defined by a mean ICP above 15 mm Hg was observed in 12 patients with meningitis (86%) and in 9 with encephalitis (69%). Patients with meningitis exhibited a very early and severe intracranial hypertension. A striking difference is noted between survivors and non-survivors who had a very high maximal ICP with a severe reduction in cerebral perfusion pressure. Intracranial hypertension occurred in all patients with acute primitive encephalitis but only in 3/7 patients with post-infectious encephalitis. ICP monitoring seems to be important in the comatose forms of bacterial meningitis in the early period, herpes encephalitis and postinfectious encephalitis with severe status epilepticus.

To determinate the importance of intracranial hypertension in central nervous system (CNS) acute infections, we studied intracranial pressure (ICP) in 27 patients, age 45 days to 13 years. Fourteen had meningitis and 13 had encephalitis; all were in deep coma with Glasgow Coma Scale 7 or less. Intracranial hypertension defined by a mean ICP above 15 mmHg, was observed in 12 patients with meningitis (86%) and in 9 with encephalitis (69%). Patients with meningitis exhibited a sudden and severe intracranial hypertension. A striking difference was noted between survivors and non survivors who had a very high maximal ICP with a severe reduction of cerebral perfusion pressure (CPP). Intracranial hypertension occurred in all patients with acute primary encephalitis but in only 3/7 patients with post-infectious encephalitis. ICP monitoring seems to be important in the comatose forms of: (1) bacterial meningitis in the early period (2) herpes encephalitis (3) post-infectious encephalitis with severe status epilepticus.

In a double-blind group comparative study, 36 adult, birch pollen-allergic outpatients with seasonal rhinoconjunctivitis, were treated with either oral prednisolone 7.5 mg daily for 3 weeks or an injection with 2 ml suspension of betamethasone dipropionate and betamethasone disodium phosphate (Diprospan) immediately prior to the birch pollen season. Both treatments were able to prevent an increase in symptoms from the nose and the eyes during the 3-week birch pollen season. There was no significant difference in symptom score or nasal peak flow between the two treatments. However, there was a significant suppression of adrenal gland function after oral prednisolone treatment in contrast to Diprospan treatment. Unless there are contraindications for treatment with depot steroid injections (children, pregnant women, patients suffering from peptic ulcer, tuberculosis, eye disease, herpes, hypertension or diabetes) it seems to be a reasonable alternative to oral prednisolone in hay fever patients.

One hundred sixty-six adult patients of a community family practice program were questioned about their understanding of the terms hypertension, virus, strep throat, herpes, tumor, Pap smear, and uterus. Significant misconceptions were common among patients of all ages and educational backgrounds, although a positive association of education and knowledge was demonstrated. In using these and similar terms, clinicians must be cautious to ensure that the patient is receiving the intended message.

In 36 subjects in chronic hemodialysis treatment and in 36 patients with a renal transplant, well functioning for more than one year, the ocular complications related to the specific form of treatment were evaluated and compared. In the group of the dialyzed subjects ocular pathology was composed by: lens opacities in 9 cases, corneal calcifications in 7 cases, hypertensive fundus in 8 cases. In no patient these lesions produced measurable visus reductions. In the transplant group ocular pathology was composed by: lens opacities in 28 patients, hypertensive fundus in 7 and intraocular hypertension in one. One case of herpes cheratytis and one case of endophtalmytis have also been observed. In 9 patients these lesions produced a remarkable visus reduction. In conclusion renal transplantation shows a greater incidence of ocular complications if compared to hemodialysis. This situation has not important consequences on the rehabilitation of the transplanted subject for the possibility of surgical correction of the cataract.

Recent studies have illustrated that in addition to the well known risk factors, such as lipoproteins, smoking, hypertension, there are others that cause atherosclerosis and myocardial infarction. Our knowledge of atherosclerotic lesions has increased. We now know that atherosclerotic changes are due to inflammatory cell infiltration as well as to increases in migration of vascular smooth muscle cells. Endothelial cells play a major role in the pathology of vascular changes. In recent years a new risk factor for coronary artery disease has been discovered: chlamydia pneumonial infections. Herpes class viruses have also been associated with pathology of atherosclerotic lesions. Studies show that dental status and bacterial infections are also related to the risk of myocardial infarction. This review discusses the possible mechanisms of infection and inflammation and whether they are major or modifying risk factors for atherosclerosis and myocardial infarction.

The causes of intrauterine growth retardation (IUGR) are multiple, involving many different factors. Studies in humans and animals have shown that the maternal environment is the most important determinant of newborn weight, accounting for more similarity in birth weights of siblings than does genetic affinity. In addition to a direct relationship with the degree of maternal plasma volume expansion, many clinical factors are associated with IUGR. These factors include multiple gestation; fetal, genetic, and chromosomal anomalies (Down's syndrome and Turner's syndrome); infections such as TORCH syndrome (acronym for toxoplasmosis, rubella, cytomegalic disease, and herpes); and various maternal disorders including anemia, severe chronic asthma, chronic renal disease, heart disease and hypertension. Maternal stress factors, including narcotic addiction, cigarette smoking and chronic alcoholism, are associated with IUGR. Placental anomalies including hemangiomas, placental infarcts, single umbilical artery, and small placental size are also associated with intrauterine growth retardation. Poor nutritional status of the mother at conception and inadequate energy and protein intakes during pregnancy can also result in IUGR. Because IUGR children are not a homogeneous group, they have a broad spectrum of growth, health, and developmental outcomes. In general they have higher rates of subnormal growth, morbidity, and neurodevelopmental problems. The biomedical mechanisms reflected in nutritional, infection-related, hormonal, and metabolic parameters are not likely to be independent causative factors of IUGR, but important mediating factors of a pathologic process set in motion by other agents and insults. This paper focuses mainly on the possible negative effects that a deficient maternal diet might have on fetal development and growth.
