Ten goats were inoculated with peste des petits ruminants virus, a paramyxovirus closely related to rinderpest virus. All goats developed severe clinical disease, 8/10 having coughing or dyspnea as prominent clinical signs. In addition, all of the goats had stomatitis and diarrhea. Histopathologic and immunohistochemical studies were done only on the respiratory tracts. Pathologic changes ranged from mild multifocal bronchiolitis and bronchitis to severe bronchointerstitial pneumonia. Lesions were more severe in anteroventral than caudal lobes. The histologic nature of the viral process in the goat lungs had many features in common with the processes of pneumonia in dogs, due to canine distemper, or pneumonia in human beings, due to measles virus. Immunohistochemical staining of formalin-fixed, paraffin-embedded respiratory tract tissue was performed using an indirect system with rabbit anti-rinderpest virus serum, biotinylated anti-rabbit antibody, streptavidin-alkaline phosphatase, and nitroblue tetrazolium chromogen. Staining was sensitive, highlighting the presence of viral antigen in both lung and trachea of all goats. Viral antigen was found in both cytoplasm and nucleus of tracheal, bronchial, and bronchiolar epithelial cells, type II pneumocytes, syncytial cells, and alveolar macrophages. In general, the amount of staining correlated directly with the severity of the inflammatory process.

During a 2-year period from January 1988 to December 1989, 125 patients (68 boys, 57 girls), aged 30 days to 9 years, were diagnosed as rotavirus gastroenteritis at this hospital. Diagnosis was made by identification of the rotavirus antigen in stool samples by latex agglutination assay. Ninety-nine (79.2%) of them were under 2 years of age. The seasonal peak in incidence was from January to March. The most common clinical characteristics were watery diarrhea (100%), followed by vomiting (68.8%), fever (68.0%), cough (42.4%), rhinorrhea (17.6%), convulsions (6.4%) and moderate to severe dehydration (1.6%). Fecal occult blood was positive in 4 patients and fecal leukocytes were positive in one patient. Stool cultures revealed concomitant infections with enteropathogenic Escherichia coli in 4 patients. Of the 106 patients who underwent serum electrolyte examinations, serum sodium concentrations ranged from 135-145 meq/L in 81.9% (86/106) and serum potassium concentrations ranged from 3.5-5.0 meq/L in 86.8% (92/106). Leukocyte counts greater than 15,000/mm3 were found in 10.8% (13/120) of the patients. All 125 patients recovered from the diarrheal illness on follow-up. Our results showed a different seasonal distribution of this disease from that of a previous observation between 1983-1984 in Taipei City and provides original clinical information on rotavirus gastroenteritis in children living in an area of Taipei County. Using the simple and rapid latex agglutination assay, we can make early diagnosis of rotavirus gastroenteritis. Thus, early treatment and early isolation of patients to prevent nosocomial infection among hospitalized patients is possible.

The diagnosis of childhood illness by maternal health interview surveys is widely used to estimate the prevalence of childhood morbidity in developing countries. To determine the validity of interview-based diagnoses, and to define simple, sensitive and specific diagnostic algorithms, we compared symptoms and signs reported by mothers during structured interviews with physicians' diagnoses for 271 children on the Philippine island of Cebu. The 271 children had 318 physician diagnosed illnesses: 105 acute lower respiratory infections (ALRI), 121 diarrhoeas, 36 measles, 50 upper respiratory infections (URTI), 5 roseola infantums and one milaria rubria. An algorithm for measles (age greater than or equal to 120 days, rash and fever greater than or equal to 3 days and fading of rash) had a sensitivity and specificity of 94%. For ALRI an algorithm of cough, dysponea and fever had a sensitivity of 82%, but specificity was lower in comparison with URTI (58%) than with children who had no respiratory illness (79%). Inclusion of signs of respiratory distress (flaring of nostrils, intercostal retraction) raised the specificity to 83-84%, but reduced sensitivity to 68%. Diagnosis of diarrhoea based on frequent loose or liquid stools had a sensitivity of 95-97% and specificity of 80% in children with or without concomitant non-diarrhoeal illnesses. Addition of questions on numbers of stools (greater than or equal to 6 per day), and no signs of dehydration increased specificity to 95% but reduced the sensitivity to 84-86%. However, specific signs of dehydration were not well reported by the mothers.(ABSTRACT TRUNCATED AT 250 WORDS)

The knowledge and opinions of health professionals of Botucatu about the frequency and severity of thirteen symptoms and signs of diseases were studied with a view to comparing then with the opinions of Botucatu's urban population. Four hundred and thirty-five active health professionals (physicians, nurses, nurse aides, health workers (orderlies) and others were interviewed. Most of them were women, with ages ranging from 25 to 44. The health workers (orderlies) were the most numerous category. In general, the last five symptoms included in the form: bloody sputum, vaginal bleeding, breast lump, seizures and bloody urine, were considered less frequent and more serious as compared with the first eight symptoms: shortness of breath, fever, weakness, back pain (backache), chest pain, headache, cough and diarrhoea. Among the categories, the physicians differed from the other categories in less frequently attributing high scores to frequency and severity. The clinicians gave more value to these two factors than the surgeons for almost all symptoms. The comparison with the opinions of the laymen interviewed showed similar tendencies although the laymen regarded frequency and severity as more significant.

In a multicenter study in general practice, the tolerability and safety of ramipril alone and in combination with a low dose of furosemide were assessed in moderate hypertension. After a placebo run-in period involving 770 patients, 661 were included in the active treatment period and received ramipril alone (2.5-5 mg/day). After 6 weeks, the nonresponders entered in a double-blind period and they received daily ramipril 10 mg or ramipril 5 mg in combination with furosemide 20 mg. In this hypertensive population, the adverse events more commonly reported were headache, cough, dizziness, asthenia, cramps diarrhea and nausea, but not all these events were related to ramipril. There was seemingly a relation between cough prevalence and rampiril dosage; an increased incidence was also observed during the outbreaks of flu-syndrome in our country. 38 patients discontinued the active treatment due to non-serious adverse events, mainly cough, dizziness or diarrhea. No serious adverse drug reaction was observed. Laboratory data (blood cells count, electrolytes, serum creatinine, fasting blood glucose, apolipoproteins AI and B) remained most commonly unaffected. In moderate hypertension in general practice, this study confirms that ramipril is well tolerated, especially with regard to the class effects of the angiotensin converting enzyme inhibitors.

Immunotherapy with interleukin (IL)-2 possesses great potential in the treatment of immune-mediated diseases and cancers. However, only a few reports on a small number of children have appeared in the literature. From March 1988 to March 1989, 11 children and adolescents were treated with IL-2. They included 1 patient with hepatocellular carcinoma, 1 with hepatoblastoma, 6 with childhood atopic dermatitis, and 3 with juvenile rheumatoid arthritis. The dosages ranged from 10,000 to 50,000 U/kg every 8 hours by intravenous drip. The following side effects were observed: anorexia, fever, and chillness (100%), general malaise (82%), irritability (64%), diarrhea (100%), nausea and vomiting (73%), weight gain (82%), edema (82%), abdominal distension (73%), oliguria (82%), cough (91%), dyspnea (27%), pleural effusion (40%), hypotension (82%), skin eruption (82%), oral ulcer (18%), enlarged liver (73%) liver function abnormalities (82%), renal function impairment (36%), electrolyte imbalance (73%), anemia (91%), thrombocytopenia (54%), leukopenia (18%), and eosinophilia (73%). Immunologically, numbers of natural killer cells were increased and natural killer and lymphokine-activated killer cell activities were augmented after IL-2 treatment. There was a tendency for serum levels of IL-2 and receptor IL-2 to decrease, especially in patients with atopic eczema. Ten patients (91%) completed one course (9 to 12 days) of therapy, and the remaining patient interrupted the treatment because of intolerable adverse effects. Clinically, complete remission for 3 months was obtained in 1 juvenile rheumatoid arthritis patient, transient improvement (2 to 6 weeks) in all atopic dermatitis patients, minor response in the hepatoblastoma patient, and no response in the patient with hepatocellular carcinoma.

The seroprevalence, clinical epidemiology, modes of transmission, clinical presentation in adults, pregnancy women and children, diagnosis, impact and control strategies of AIDS in Africa are covered in this review. HIV-1, the causative virus in AIDS, is epidemic in a central Africa belt from Gabon to the east coast, and from Uganda to Zimbabwe, with the highest prevalence in the lakes and highlands of Central Africa. HIV-2 causes a milder disease in Western Africa centered in Senegal. HIV infections occur primarily in young adult men aged 30-34, women aged 20-24, infants and children under 4, and a few girls. Transmission patterns vary widely depending on sexual customs in the ethnically diverse continent. Prevalence tends to be high in cities and among subgroups such as prostitutes, where promiscuity is restricted. Where female sexual permissiveness exists, seropositivity is high in women generally. Besides sexual behavior, risk factors for HIV in Africa also include uncircumcised man, oral contraception, STDs causing genital ulceration and Chlamydia infection. Transmission to neonates occurs, especially if the mother has advanced AIDS, but transmission by breast milk is uncertain. Transmission by blood transfusion is common because transfusion are up to 10 times as common in Africa as in the West, especially in obstetrics and pediatrics. Clinically, HIV infections present as herpes zoster in 95% of Africans, and commonly as slim disease: weakness, fever, chronic watery diarrhea and weight loss of unknown cause. Associated infection are candidiasis, cryptosporidiosis, isosporiasis, tuberculosis and salmonellosis. Other presenting symptoms are unusual sites of lymphadenopathy, cough and sepsis. Diagnosis can be made by the WHO clinical case definition, or be screening tests, which are now more reliable for African patients than formerly. In Africa, AIDS can cause destitution and disgrace for families, and will probable severely affect progress made national economies because of deaths of young productive adults. Strategies for control of HIV in Africa are outlined.

A survey of the health, social and economic problems of the village of A1 Awayda, in Gezira province, Sudan, by medical students, was conducted over 2 weeks as part of their field training research and rural development curriculum. A 40% random household survey was based on a pretested structured questionnaire. The village comprises 195 households of 1201 people, with 40% under 15. As a result of the Sennar Sugar Scheme begun in 1978, 58% of the population work in the sugar factory. Rain-fed crops have failed for the last 2 years because of drought, and subsistence acreage has contracted because of sorghum planting for sugar. Sanitation consists of latrines in 15% of houses. People are at risk of contracting schistosomiasis from crossing the irrigation canal to reach the well. The diet is based on the staple starch, dura in the form of kisra. Breast feeding is continued for 1-2 years, with 47% supplementation by bottle or kisra or rice water at an average of 7 months. The major health problems are malaria, schistosomiasis, cough and diarrhea. 54% of families were immunized. 11.5% of women used modern contraceptives. Non-users cited religion as a reason for non-use. Female circumcision is common. It was recommended that latrines be dug, and that health education, immunization, prenatal care and family planning be provided.

Recently there has been extensive development of orally active angiotensin converting enzyme (ACE) inhibitors in addition to those already marketed, for example, captopril, enalapril, lisinopril and ramipril. It was initially thought that ACE inhibitors were likely to be most useful as antihypertensive agents in conditions in which circulating renin and angiotensin II were elevated. However, it is now clear that they can also lower arterial pressure when plasma renin is not high. In addition, they have beneficial effects in cardiac failure. Thus, captopril, enalapril, lisinopril and ramipril can be used in the treatment of mild to moderate hypertension either alone or in conjunction with diuretics or calcium antagonists. Broadly speaking, efficacy appears to be similar to that of beta-blockers or diuretics. Unfortunately, however, there are no long term studies comparing one ACE inhibitor with another or with other classes of antihypertensive agents. Furthermore, there are no prognostic studies which show that use of ACE inhibitors reduces morbidity or mortality in hypertension. Many new ACE inhibitors are undergoing clinical assessment, including alacepril, cilazapril, fosenopril, perindopril, quinapril and ramipril. The drugs vary, in that some exist in the active form whereas others are prodrugs which are converted to the active agent following absorption. In addition they each possess one of several ligands, for example, carboxyl, phosphinyl or sulfhydryl groups, and so vary in their affinity for ACE. Although many of these agents are renally excreted, a small number are metabolised via the liver (e.g. quinapril and spirapril) and this may prove advantageous in the presence of renal impairment. In common with captopril and enalapril, the new ACE inhibitors inhibit the renin-angiotensin system and initial results suggest that they are effective in lowering blood pressure in essential hypertension. Furthermore, they reduce systemic vascular resistance in the absence of a reflex tachycardia. There are a number of adverse effects which are attributable to the pharmacological mechanism of the ACE inhibitors as a group; these include hypotension, particularly in patients with high renin levels, prior diuretic use, renal impairment or in the elderly. Additional adverse effects may relate to chemical structure. The high incidence of adverse effects noted in early studies related to excess dosage and to the presence of a sulfhydryl group, which the more recently developed ACE inhibitors lack. The adverse effects most commonly reported with established and new ACE inhibitors include headache and fatigue, cough, skin rashes, hypotension and diarrhoea. As a group, ACE inhibitors have an acceptable but not negligible adverse effect burden.(ABSTRACT TRUNCATED AT 400 WORDS)

Simple cardiopulmonary functions were studied serially in 26 mountaineers between sea level and an altitude of 25,200 ft. Up to 12,000 ft there was no altitude sickness, though there were complaints of leech bite (26.9%) and blisters (3.8%). One member died of exhaustion, two developed pulmonary oedema, one "flu" (at 15,600 ft) and one pleural rub (at 21,000 ft). Up to 16,000 ft altitude, 4 to 7.7% developed diarrhoea or epistaxis only, but at higher levels 25 to 50% subjects developed several symptoms, besides excessive dyspnea. These included diarrhoea (35-60%), vomiting (30%) abdominal pain (35-60%), rectal bleeding (15%), chest pain (10-40%), dry cough (40-60%), giddiness (30%) and poor memory (7.7%). A small rise in blood pressure was seen (for systolic at lower and diastolic at greater altitudes). After 18,200 ft the steady increase seen in VE slowed and the rise in heart rate and respiratory rate (f) became steeper. After a small rise at 7,800 ft, FVC and FEV1 showed a gradual decline at higher altitudes. After a large initial increase in PEFR up to 12,000 ft, a gradual decline was seen. The mean weight loss during the expedition was 8 +/- 2.7 kg. These changes seem to be due to an incomplete acclimatisation, which future mountaineering teams should take into consideration to avoid health problems and improve performance.
