A prospective case series study was conducted Jan 1991-Oct 1991 on 108 neonates admitted to NICU, Lusaka. 90 patients satisfied inclusion criteria, 45 cases and 45 controls. Symptomatic seropositive babies born to seropositive mothers presented with failure to thrive, fever, persistent or recurrent thrush, severe Sepsis and large liver. Tendency to prematurity among cases was high. Diarrhoea, Sepsis and Haemolytic Anaemia appear to be terminal signs. Neonates suffer the most aggressive form of HIV/AIDS, with symptomatic cases dying 3-4/52 of onset of symptoms. Over one quarter of the mothers were symptomatic. Congenital malformations and Lymphadenopathy were not significantly associated. Microcephaly occurred in association with failure to thrive and was not an isolated finding.

Chloroquinoxaline sulfonamide (CQS) is a halogenated heterocyclic sulfanilamide identified by the in vitro human tumor colony-forming assay as an active agent in a variety of human solid tumors. In this phase I study, 182 courses of CQS were administered intravenously every 28 days to 88 patients at doses ranging from 18 to 4870 mg/m2. Hypoglycemia associated with hyperinsulinemia was the dose-limiting adverse effect at 4870 mg/m2. Supraventricular tachyarrhythmias were observed at doses > 4000 mg/m2. Less common reactions included infusion site phlebitis, nausea, anemia, alopecia, perioral numbness, and diarrhea. Cumulative toxicity was not observed. Minor objective antitumor responses were noted in 7 patients; 6 of the 7 responses occurred in patients with non-small cell lung cancer. Results of pharmacokinetic studies were consistent with the preclinical observations that CQS is highly bound to plasma protein. Plasma elimination followed a two-compartment model; the mean t 1/2 alpha was 2.7 +/- 0.3 h and the t 1/2 beta was 52 +/- 6 h (+/- SE). The total body clearance and the volume of distribution at steady state of CQS both increased with the dose (distribution at steady state, 3.7-10.5 liter/m2; total body clearance, 53-264 ml/h/m2 for doses of 18-4060 mg/m2) and may reflect saturation of the protein binding and "free" drug clearance. Although inactive against common animal tumors in preclinical screening systems both in vitro and in vivo, CQS has demonstrated definite activity in the human tumor stem cell colony-forming assays, as well as modest anticancer activity in this phase I study in patients with advanced solid tumors. The pharmacokinetic results and the limiting effect of transient hypoglycemia suggest that considerably higher cumulative doses of CQS could be administered using a more frequent dosing schedule.

Infections with Ancylostoma caninum are transmitted orally or percutaneously. The transmission of infectious stages with the milk of particular importance for the distribution of the species. It occurs during the dissemination of larvae that follows every infection as well as after reactivation of resting somatic larvae in the bitch at the end of the pregnancy. The galactogenic transmission of larvae occurs even when, due to existing immunity, no patent infections develop in the bitch. Immunity does not or only to a low extent influence impatient infections or the migration of reactivated somatic larvae. It also allows a limited reestablishment of a deposit of larvae in the bitch. Following percutaneous infection dermatitis occurs in the area of larval penetration and the lung is affected by migrating larvae. Intestinal stages of Ancylostoma caninum damage the host by ingestion of the mucosa of the small intestine and withdrawal of blood. Main symptoms of ancylostomiasis are a mucous haemorrhagic diarrhoea and anaemia, that become visible 8 to 10 days post infection. The examination for impatient infections with Ancylostoma caninum can be done by immunofluorescence and ELISA. With both methods antibodies against third stage larvae can be detected from the first or second week post infection onward. Patent infections with Ancylostoma caninum can easily be detected by faecal examination for the presence of the characteristic oval, thin-walled eggs containing few blastomeres. Galactogenic infections with Ancylostoma caninum can be prevented or reduced by a regular treatment of the bitch with albendazole, fenbendazole or oxfendazole during the activation of larvae in the last third of the pregnancy or by repeated treatment with ivermectin shortly before and after birth. To prevent patent infections, galactogenic infected puppies have to be treated early and repeatedly.

WHO finds that the health services and the health systems in India have improved. For example, India has made considerable improvement in expansion of health services to rural areas (7-10% expansion) and to the poor. Further, allocation to the minimum needs program, according to the state sector plan, has risen from 42.6% to 50%. In addition, infant and maternal mortality rates have fallen. Improved immunization coverage, prenatal care services, diarrhea prevention, malaria control, and contraceptive use have all contributed to the reduction in infant and maternal deaths. Health and welfare programs have generally institutionalized the primary health care concept of community participation. Training for health workers, policymakers, and personnel from nongovernmental organizations has expanded. Nevertheless, life expectancy has essentially not changed. Besides, WHO notes that the disease patterns have not changed. Some regions of India have disease patterns of developed countries, however. India has the highest number of malaria cases in southeastern Asia (almost 71%) and the second highest number of women with anemia. The number of HIV-positive and AIDS cases is growing. More than 374 million people are at risk of lymphatic filariasis, and Japanese encephalitis has become entrenched in India. 5% of the population are positive for hepatitis viruses. 1% have iodine deficiency disorders.

A clinical AIDS case definition is needed for surveillance in countries where the CDC case definition is not practical. To derive such a definition, we compared 110 HIV-seropositive and 135 randomly selected HIV-seronegative adult medical-ward inpatients in Brazil. Multivariate analysis of clinical signs and symptoms and simple diagnoses resulted in a discriminant function with sensitivity of 89% and specificity of 96% in predicting for AIDS. These data were the empirical basis for a clinical definition of AIDS in adults drafted in a Caracas, Venezuela, workshop sponsored by the Pan American Health Organization. The revised "Caracas" definition presented here requires a positive HIV serology, the absence of cancer or other cause of immunosuppression, plus > or = 10 cumulative points, as follows: Kaposi's sarcoma (10 points); extrapulmonary/noncavitary pulmonary tuberculosis (10); oral candidiasis or hairy leukoplakia (5); cavitary pulmonary/unspecified tuberculosis (5); herpes zoster < 60 years of age (5); CNS dysfunction (5); diarrhea > or = 1 month (2); fever > or = 1 month (2); cachexia or > 10% weight loss (2); asthenia > or = 1 month (2); persistent dermatitis (2); anemia, lymphopenia, or thrombocytopenia (2); persistent cough or any pneumonia except TB (2); and lymphadenopathy > or = 1 cm at > or = 2 noninguinal sites for > or = 1 month (2). This definition has a sensitivity of 95% and a specificity of 100% (91% without HIV serology) when applied to the Brazilian patients in this study. The Caracas definition has been adopted by Brazil, Honduras, and Surinam, and is in validation elsewhere. The use of a reasonably sensitive and specific case definition commensurate with available diagnostic resources should facilitate AIDS surveillance in developing countries.

A total of 25 patients with metastatic renal cancer were treated on a phase II protocol with 5 days of continuous-infusion fluorodeoxyuridine (FUDR), (0.1 mg/kg daily) together with high-dose oral leucovorin (100 mg 4 h) and daily x6 high-dose interferon-alpha 2b (30 x 10(6) IU/m2). Despite the good performance status of the patients and the inclusion of 14 previously untreated patients in the cohort, no response was observed among the 20 evaluable patients. Toxicities included high fever, moderate anemia, transient leukopenia, transient and mild elevations of transaminases, and moderate to severe nausea, vomiting, diarrhea, and mucositis. There were also two episodes each of confusion, fluid retention, and pancreatitis and one episode of increased creatinine levels. During the study three deaths occurred, two of which were possibly therapy-related. Despite previous reports of activity of FUDR in metastatic renal cancer, the present regimen cannot be recommended.

Gastrointestinal symptoms were present at the time of diagnosis in 81 (76%) of 107 patients with coeliac disease: 56% had diarrhoea/steatorrhoea, 32.7% abdominal pain and 15% constipation. Gastrointestinal symptoms were commonest in young adults (20-39 years) and less frequent in children (0-19 years). Anaemia, low serum levels of folic acid, albumin and calcium, and raised serum alkaline phosphatase may be of help in raising the index of diagnostic suspicion, but in over half of our patients with clinically and histologically active disease these values were within normal limits. In patients adhering to a gluten free diet remission of symptoms correlated well with histological response; the continuation of symptoms indicated a higher incidence of histological abnormality. No patient not complying to the diet had normal histology on repeat biopsy. Five patients died over the ten year period, one from a small bowel lymphoma.

A patient with the Pearson marrow and pancreas syndrome is presented. She showed an anaemia with neutropenia and thrombopenia, failure to thrive, diarrhoea, disturbed glucose homeostasis and lactic acidosis. An exocrine pancreatic insufficiency was lacking. The disease followed a fatal course. Biochemical investigations of skeletal muscle revealed a disturbed mitochondrial energy metabolism, while many ultrastructural abnormal features were observed in the muscle tissue. Molecular genetic studies showed a de novo deletion in the mitochondrial DNA (mtDNA), different in size from the already published deletions and flanked by two 4 bp direct repeats, interspaced by 4-5 non-repeated nucleotides. mtDNA from 12 other tissues showed the same deletion in different percentages. No obvious relation between these percentages and tissue dysfunction was found. In spite of an open reading frame of 74 codons, only little transcription product of the genomic region resulting from the deletion was found.

The clinical features and results of laboratory investigations of the first 19 Indian patients with AIDS seen in our hospital are presented. Weight loss, fever, and diarrhea were the most common symptoms. Tuberculosis (TB) was the most common secondary infectious disease; among 13 patients, seven had only pulmonary TB, five had pulmonary and extrapulmonary TB, and one had only extrapulmonary TB. Oropharyngeal candidiasis was found in 11 patients. Other secondary infections were predominantly by virulent bacteria. Opportunistic infections other than candidiasis were infrequent; one patient had cryptococcosis, two had symptomatic cryptosporidiosis, one had noncoagulase-positive staphylococcus septicemia, and one had cytomegalovirus retinitis. Reduced lymphocyte counts (particularly of the CD4 subset), anemia, hypoalbuminemia, hyperglobulinemia, and elevated liver enzyme levels were frequent laboratory findings. Six patients are under follow-up, two are lost to follow-up, and 11 have died. Lymphocyte counts less than 500/mm3 were only seen in those patients who subsequently died. Response to antituberculosis therapy was good in several patients. Thus, the clinical profile of Indian patients with AIDS is not different from the common picture of patients of low socioeconomic and poor hygienic standards; patients presented with TB, undernutrition, and multiple infections. Therefore, a large population of patients with AIDS in India will not be recognized unless they are tested for evidence of HIV infection.

1. Minimum inhibitory concentrations (MICs) of levofloxacin (LVFX, DR-3355), ofloxacin (OFLX), tosufloxacin (TFLX), norfloxacin (NFLX) were determined, with an inoculum size of 10(6) cfu/ml, against 122 strains of Staphylococcus aureus isolated from lesions of skin infections. LVFX showed most frequent MIC values of 0.20 micrograms/ml. OFLX, TFLX, and NFLX showed most frequent MIC values of 0.39 micrograms/ml, less than or equal to 0.05 micrograms/ml and 0.78 micrograms/ml, respectively. 2. Serum and skin levels of LVFX after oral administration (10 mg/kg, fasting) were determined in rats. Serum levels were 1.79, 1.29, 0.60, 0.43 and 0.18 micrograms/ml, and corresponding skin levels were 1.63, 1.77, 1.04, 0.87 and 0.64 micrograms/g (wet weight) at 0.5, 1, 2, 4 and 8 hours after administration (n = 5), respectively. 3. LVFX was used clinically in 43 cases at doses of 200-300 mg divided into 2 or 3 doses, and evaluated for final overall clinical efficacy in 41 cases. Cure was observed in 21 cases, remarkable improvement in 13 cases, improvement in 4 cases, unchanged in 1 case, aggravation in 1 case, and remarkable aggravation in 1 case. Diarrhea was observed in 2 cases, diffuse erythema with feverishness in 1 case and slight dyspnea in 1 case. Transient slight eosinophilia, elevation of Al-P, anemia and leukopenia were observed.
