In this study, the tolerability and safety of ramipril, as monotherapy and in combination with a low dose of furosemide, were assessed in patients with mild-to-moderate hypertension in general practice. After a placebo run-in phase, patients received ramipril as monotherapy in a dose of 2.5 to 5 mg daily for 6 weeks. Nonresponders (diastolic blood pressure greater than 90 mm Hg) entered a double-blind treatment period, and received either 10 mg of ramipril daily, or 5 mg of ramipril in combination with 20 mg of furosemide daily. The tolerability of the study medication was assessed by reported adverse events, and by monitoring blood cell count, electrolytes, serum creatinine, fasting blood glucose, and apolipoproteins AI and B. Of a total of 770 patients who entered the placebo run-in phase, 661 patients were enrolled in the first active treatment period. The most commonly reported adverse events were headache, cough, dizziness, asthenia, cramps, diarrhea, and nausea, but not all of these events were related to ramipril treatment. A total of 38 patients discontinued active treatment due to nonserious adverse events, mainly cough, dizziness, or diarrhea. There appeared to be a relationship between the prevalence of cough and ramipril dosage; however, an increased incidence of cough was also observed during outbreaks of influenza in France. There were no significant changes in laboratory variables during the study.

60,000 women in France have received RU 486 and a prostaglandin to induce abortion. In the late 1980's, clinical researchers assessed the safety and effectiveness of 600 mg of oral RU 486 in 2040 French women. 2 days later, health workers either injected 0.25-0.5mg of sulprostone or inserted a 1mg vaginal suppository of gemeprost in 1964 women who had not yet aborted. 96% experienced complete abortions. Physicians needed to conduct either a vacuum aspiration of dilation and curettage on the other 4%. RU 486 was most successful with 0.5mg of sulprostone, but these women also experienced considerable vaginal bleeding and pain. Overall uterine bleeding occurred for 8.9 days. The researchers recommended that adequate medical facilities be accessible to women using this method. Mild side effects were nausea, vomiting, and diarrhea. Efficacy and safety matched those of other early abortion methods. In April 1991, a grand multiparous women who smoked heavily and received RU 486 and a prostaglandin died--the 1st reported RU 486 related death. RU 486 may be able to treat fibroids, endometriosis, premenstrual syndrome, meningioma, hypertension, adrenal cancer, glaucoma, some forms of Cushing's syndrome, and breast cancer. The US Food and Drug Administration forbade the commercial import of RU 486 in 1989, even though it deemed RU 486 safe and effective. FDA considered the antiabortion view of the Bush Administration when making this decision. It made this decision despite the fact that abortion was still legal. RU 486 should be available soon for use as an abortifacient in the UK, the Netherlands, Sweden, Norway, Denmark, and Finland. These countries do not intent providing it to US women, however. Further the manufacturer is not willing to provide it to US researchers because it is afraid of antiabortion repercussions which may jeopardize WHO's approval of RU 486.

Between 1982 and 1989, 78 children with diarrhoea-associated haemolytic uraemic syndrome (HUS) were referred to this hospital. Most presented with abdominal pain, bloody diarrhoea and vomiting. Seven had severe gastrointestinal involvement, four of whom required resection for bowel perforation or necrosis. One also developed an oesophageal stricture, a previously unreported complication of HUS. These seven children had a high incidence of other complications including hypertension, and cerebral and pancreatic involvement. One died from severe cerebral involvement, one has a residual neurological deficit and one has residual renal impairment. Severe gastrointestinal involvement did not significantly affect the long-term outcome. Simple haematological indices helped predict severe gut involvement. Four of the 78 children had undergone appendicectomy before the diagnosis of HUS was made. The operative findings were in no case typical of primary acute appendicitis, although histological examination did confirm inflammation of the appendix in two patients. Diagnosis is difficult in early disease, but increased awareness may help prevent unnecessary appendicectomy.

Between 1985 and 1988, a two-phase epidemiological study was conducted at the "Ruta 100" company in Mexico City to examine the harmful effects of the working conditions on drivers of urban transport vehicles. In the first phase, five groups of nine drivers each were interviewed regarding their opinions about their working conditions and possible work-related disorders. On the basis of this information, an epidemiological survey was developed and applied using a polytypic sampling design to some 200 drivers plus two other groups of approximately the same size, one consisting of maintenance workers and the other of office workers, which served as controls. The driver group showed a high prevalence of respiratory and neuropsychiatric disorders, diarrhea, myopia, arterial hypertension, urinary disorders, hemorrhoids, hearing loss, back pain, varicose veins, peptic ulcers, diabetes, cardiopathies, abdominal hernias, and appendicitis. For arterial hypertension, hemorrhoids, nervous disorders, and psychiatric disorders the prevalence ratios of drivers/maintenance workers and drivers/administrative workers were statistically significant.

This case report describes a 15 months-old patient with Wilms' tumor, who was treated with radical operation and chemotherapy. During hospitalization the patient suffered from recurrent lung infections, which were treated with appropriate antibiotics. Subsequently, the patient developed severe abdominal affection with daily melena, liver and kidney involvement, and generalized edema and hypertension. Cl. difficile and its cytotoxin was demonstrated in feces, and the patient was successfully treated with vancomycin. Although rare, Cl. difficile may cause severe generalised illness in children under two years of age, and it is important to examine any infant with abdominal symptoms for the occurrence of Cl. difficile, even though no diarrhoea is present.

The failure of up to half of all patients in developing countries to adhere to recommended drug regimens may reflect inadequate physician- provider communication rather than resistance to treatment. There is substantial evidence that patients are more likely to conform to treatment regimens when they are fully informed about their medical condition and the medication prescribed. To investigate the extent to which patients in Zimbabwe received this type of information, household heads in 910 households in the Mashonaland West Province were interviewed. The sample included equal numbers of respondents from urban, rural, and commercial farming areas. Diseases most commonly reported by rural residents and farmers were diarrhea, influenza, cough, hypertension, and malaria. Most of the illnesses were attributed to natural or supernatural causes, and 80% of respondents in these subsamples claimed to distrust their health care provider and never asked questions about medications prescribed. The rural residents perceived health care personnel as too busy to answer questions and did not believe they would understand any information offered. On the other hand, these respondents indicated they would like to have information on the cause of their illness, its duration and treatment, the best way to take prescribed drugs, actions to take when drugs produce side effects, and storage of medication. Physicians who treat semi-literate rural residents with indigenous health beliefs are urged to provide information about medication tailored to match the individual perceptions and needs of the patient. This need is less urgent in urban areas, where 60% of respondents had general knowledge about the action of various medicines and were able to obtain information from pharmacists.

Sixteen patients with relapsed non-Hodgkin's lymphoma underwent autologous bone marrow transplantation and infusion of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF). Treatment consisted of involved-field radiotherapy, cyclophosphamide 60 mg/kg/d intravenously (IV) for 2 days, and fractionated total body irradiation (1,200 cGy). Autologous bone marrow was thawed and infused IV, followed 3 hours later by the first infusion of IV rhGM-CSF 11 micrograms/kg/d over 4 hours. Infusions of rhGM-CSF were continued daily until either both neutrophil count exceeded 1,500/microL and platelet count exceeded 50,000/microL, or until 30 days after marrow re-infusion. Toxicities encountered were mild and included fever, chills, hypertension, alopecia, rash, diarrhea, stomatitis, myalgias, and synovial (knee) effusions. Neutrophil recovery greater than 500/microL occurred a median of 14 days (range, 9 to 30 days) after marrow infusion, significantly earlier than in a comparable group of historic controls who recovered counts at a median time of 20 days (range, 12 to 51 days) (P = .00002). Median time to self-sustaining platelet counts greater than 20,000/microL was 23.5 days (range, 12 to 100 days), comparable with the historic group (P = .38). One bacteremia (central venous catheter exit site infection with Staphylococcus epidermidis) and one local infection (Giardia lamblia in stool) occurred. Patients received a median of 11.4 (range, 4.4 to 20.2) x 10(4) colony-forming unit granulocyte-macrophage (CFU-GM) progenitors per kg. Stem cell progenitors CFU-GM, CFU-granulocyte, erythroid, monocyte, megakaryocyte (CFU-GEMM), and burst-forming unit-erythroid (BFU-E) were detected in the bone marrow as early as 7 days after marrow re-infusion, and increased in proportion to peripheral blood counts, but by 30 to 60 days still remained much lower than before transplant. Neutrophils transiently decreased in 13 of 16 patients (median decrease, 42%) within 24 to 72 hours of discontinuing rhGM-CSF infusions. These data suggest that rhGM-CSF therapy enhances neutrophil recovery by forcing stem cells to produce mature elements at an enhanced rate but may not affect marrow stem cell and early progenitor population sizes.

A case of polyarteritis nodosa (PN) in childhood involving various organs such as the gastrointestinal tract, skin, CNS, kidneys and liver with hypogammaglobulinemia is reported. This 6 month old girl was admitted to our hospital with vomiting, diarrhea, bloody stools with mucous and weight loss. For the past 5 months she had these abdominal symptoms. She was diagnosed as having PN of the Kussmaul-Maier variety on the grounds of the biopsy of skin lesion where a necrotizing vasculitis was found. Prednisolone and methylprednisolone pulse treatment were not effective in suppressing the progress of the disease. At the age of 1 year 7 month a combination therapy of prednisolone and immunosuppressants (cyclophosphamide) was started and this was found to be effective. She was discharged when she was 2 year and 2 month. The dosage of prednisolone was tapered as the activity of the PN decreased and she did well with a maintainance dosage of 9.5 mg/day. At 3 year 6 month of age she suddenly developed hypertension (the plasma renin activity was found to be 16.6 ng/m/hr. and the aldosterone 220 ng/dl). CNS involvement such as spinal cord dysfunction, left sided convulsions, cerebral hemorrhage developed 5 months later. Methylprednisolone pulse therapy was performed 3 times and 2 mg/kg/day of prednisolone was administered. In spite of this therapy she passed away with a massive cerebral hemorrhage at the age of 4 year 8 month. Unfortunately an autopsy was not performed. Results of the immunological tests proved that the hypogammaglobulinemia was a common variable immunodeficiency (CVI). It has been reported that primary immuno-deficiency syndrome is often associated with collagen disease and auto-immune disease. This lack of the defense mechanism against the virus or extra antigen could be related to the onset of collagen and auto-immune disease. As the correlation between CVI and PN has not been clarified this case is of interest as concerns the cause of PN.

Genetic factors are known to play an important role in the variations in blood pressure levels. However, genetic factors that explain the higher average blood pressure levels of western hemisphere blacks when compared with African blacks have not been seriously considered. Because the genetic makeup of a population is largely determined by biological and ecological forces in the past, an examination of the biohistory of blacks, specifically the slavery era, was conducted. An overview of the salient findings of that investigation is included in this article. The published historical evidence on the transatlantic slave trade and New World slavery (from the 16th century to the 19th century) reveals that conditions existed for "natural selection," and therefore, genetic changes were virtually inevitable in the slave populations. During this period of history, mortality was extremely high, and fertility (or reproductive success) was so low among the survivors that most plantation societies in the western hemisphere depended on a constant importation of captives (over 12 million) from Africa for the viability of the plantation communities. Because the major causes of death were salt-depletive diseases such as diarrhea, fevers, and vomiting, it is argued that individuals with an enhanced genetic-based ability to conserve salt had a distinct survival advantage over others and were, therefore, more likely to bequeath their genotype to subsequent generations of Western hemisphere blacks. Thus, it is predicted that blacks in the Americas have a greater frequency of individuals with an enhanced genetic-based ability to conserve salt than African blacks.(ABSTRACT TRUNCATED AT 250 WORDS)

A study was conducted among women in Khayelitsha to determine the relationship between urbanisation, health status and use of health services; 722 households were visited, and 659 female respondents provided information on acute and chronic illness for the 3,229 individuals who were members of their households. In addition, they provided information concerning their reproductive health, AIDS awareness, knowledge of cervical smears and use and knowledge of health services. Acute illness was reported for 4.3% of the study population, the commonest complaints being diarrhoea, abdominal pain and upper respiratory infections; 4.4% reported chronic illness, the commonest complaints being hypertension and tuberculosis; 16.2% of women reported gynaecological illness; 86% had of heard of AIDS (although their knowledge of transmission and prevention was poor); and 45% had heard of cervical smears. Patterns of illness and knowledge and use of health services vary in the different areas of residence of Khayelitsha. This appears to be related to urbanisation, age, and environmental and socio-economic factors.
