This study examines the impact of HIV-1 infection and AIDS on 500 of 563 consecutive deaths at University Hospital, Kinshasa, Zaire, in late 1987. HIV-1 seroprevalence was 31% for the entire population and 43% for the 247 adults. Forty-two (38%) of the 110 HIV-1-seropositive adult deaths occurred in those between the ages of 25 and 34 years. The mean age of death for seropositives was 36 years, 7.5 years less than seronegative deaths. AIDS and AIDS-associated diagnoses such as cryptococcal meningitis, chronic diarrhea and pneumonia accounted for 42% of all adult deaths and 74% of all HIV-1-seropositive adult deaths. Seventeen per cent of 50 sera initially negative by enzyme-linked immunosorbent assay (ELISA) were ultimately found to be HIV-1-seropositive by Western blot or p24 antigen testing. The data indicate that HIV-1 infection and AIDS contribute significantly to adult mortality in Kinshasa population and that sensitivity of ELISA tests decreases in terminal HIV-1 infection.

Cancer patients were randomized to receive an every 4 hour or every 8 hour schedule of cefoperazone plus aztreonam during 617 febrile episodes. The overall response rate for the 478 evaluable episodes was 76% and there was no difference in response rate between the two schedules. The response rate was 79% for cases of pneumonia and 63% for cases of bacteremia. Only 50% of the microbiologically documented infections caused by gram-positive organisms responded whereas 95% of gram-negative infections, including all of those caused by Pseudomonas aeruginosa, responded. Response rates were lower among patients whose neutrophil counts decreased during therapy than among those whose neutrophil counts increased (64% vs. 85%, p = 0.008). Side-effects that were possibly or probably related to antibiotic therapy were observed during 11% of the episodes. The most common side-effects were diarrhea and rashes including one case of Stevens-Johnson syndrome. Three patients developed a coagulopathy during therapy. Cefoperazone plus aztreonam proved to be an effective combination for treatment of gram-negative infections and fever of unknown origin in cancer patients and an every 8-hour schedule of administration was as effective as an every 4-hour schedule. Approximately half of the patients with gram-positive infections required additional antibiotics for successful therapy.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

Eight cases of mother-to-child transmission of HIV-2 were documented by ELISA and Western blot in Gambia between January 1988-September 1989 from a hospital-based screening of 205 malnourished children, 864 subjects in a malaria study, 34 patients with probable immunodeficiency and 24 children of 17 HIV-2 seropositive mothers. AIDS was diagnosed by WHO clinical definition. Diagnosis of HIV-2 was made if sera were positive by ELISA and Western blot (LAV Blot2, Diagnostics Pasteur, Marnes-La-Coquette, France) and negative by Wellcozyme I competitive ELISA to HIV-a (Wellcome Diagnostics, Dartford, UK). The children ranged in age from 17 months-5 years, and in ponderal index from 50-90%. 6 had CD4 percentages or counts below the normal range. 7 of the 8 could only have been infected pre- or perinatally, while 1 had been transfused from her mother. The clinical features included 5 with diarrhea 1 month; 3 with Cryptosporidium, 3 with Candida, a pneumonia, an interstitial pneumonia by x-ray, a streptococcus abscess, a staphylococcus abscess, 1 infant with failure to thrive and 1 4-year old who was asymptomatic. This group of patients was more severely affected than a series reported from Guinea Bissau: their mothers also had advanced AIDS in comparison to asymptomatic mothers in the other series. While mother-to-child transmission of HIV-1 occurs in approximately 33% of children of HIV-1 seropositive mothers, these data cannot estimate the actual rate of transmission of HIV-2.

Features of typhoid fever were correlated with age and gender through a review of the charts of 552 hospitalized culture-positive patients with diarrhea in Bangladesh. Seizures occurred more frequently in children from birth through 10 years of age (5%-11%) and pneumonia more frequently in children from birth through 5 years of age (8%-15%) than in older age groups (P less than .05), whereas intestinal perforation occurred more frequently in patients greater than or equal to 11 years of age (5%-25%) than in younger age groups (P less than .005). Compared with older age groups, children from birth through 10 years of age were more anemic, those from birth through 5 years of age had a higher mean white blood cell count, and those from birth through 1 year of age had a lower mean blood carbon dioxide content (all P less than .05). Female patients were more severely anemic than male patients (P less than .05). The case-fatality rate was 4.3% overall, with the highest rates for children from birth through 1 year of age (11%) and adults greater than or equal to 31 years of age (10%). Female patients had a higher case-fatality rate (6%) than male patients (3%), although the difference was not significant (P greater than .05). Death was independently associated with seizures, intestinal perforation, pneumonia, and delirium or coma. These results indicated that the patients with typhoid fever who were at highest risk of complications and death were children from birth through 1 year of age and adults greater than or equal to 31 years of age.

Thirty-nine and 47 randomly selected Colorado cow-calf operations participated in the National Animal Health Monitoring System (NAHMS) during rounds 2 (October 1986 to September 1987) and 3 (October 1987 to September 1988), respectively. Data on the incidence of disease conditions within each herd were collected by federal and state Veterinary Medical Officers and university veterinarians through monthly visits to the ranches. Annual disease incidence for disease classes and the most frequently reported individual disease conditions were determined and expressed on a per 100 cow basis. The mean annual disease incidences for all diseases in these herds were 48.8 and 47.7 new cases per 100 cows for rounds 2 and 3, respectively. The ranges for herd annual disease incidence were wide in both study years. The enteric disease class had the highest mean annual disease incidence in both years of the study, and this was primarily because of diarrhea of unknown cause in calves. Diarrhea of unknown cause accounted for approximately 25% of all new disease cases in both rounds of the study. The mean annual disease incidences were not different for any disease class between the two rounds. The data indicate that, on the average, diarrhea of unknown cause, pneumonia, dystocia, foot rot (interdigital necrobacillosis), pinkeye (infectious keratoconjunctivitis), respiratory tract infection, death of unknown cause, and nonpregnancy had the highest incidences in these Colorado beef herds during the study period. However, because of the wide variation of the predominant disease problems between herds, a herd's disease history as well as the common disease problems in the geographic area of a herd must be considered in designing a herd health program.

Cefixime (CFIX) was evaluated clinically in pediatric respiratory tract infections, particularly those caused by Haemophilus influenzae: 1. The total number of children in this study treated with CFIX was 232, out of which 215 cases were evaluated for clinical efficacy and 224 cases were investigated for safety. A daily dosage of 3-6 mg/kg/day was given divided into 2 to 3 times daily for 3-15 days. 2. Causative organisms were identified in 146 cases, out of which 128 cases were found to be single microbial infections and 18 cases were mixed infections. In single microbial infections, clinical efficacy was 100% for those caused by H. influenzae/Haemophilus parainfluenzae, and was 95% for Streptococcus pyogenes with an overall efficacy of 96.9%. In mixed infections, the clinical efficacy was 100% for those caused by a combination of H. influenzae and Streptococcus pneumoniae, and the overall rate was 94.4%. An involvement of H. influenzae was observed in 108 cases with a clinical efficacy rate of 99.1%, and definite involvement of beta-lactamase secreting strains of H. influenzae was found in 32 cases with a clinical efficacy of 96.9%. 3. Bacteriological effect was studied for 164 strains identified in 146 cases, and eradication rates were 89.5% for H. influenzae, 100% for H. parainfluenzae and S. pyogenes, and 71.4% for S. pneumoniae. The overall eradication rate was 91.4%. Superinfection was observed in 21 cases. MICs against 78 strains of H. influenzae were in a range of less than or equal to 0.10 microgram/ml regardless of beta-lactamase production, and far superior to cefaclor and amoxicillin. MICs against S. pyogenes and S. pneumoniae were in ranges of less than or equal to 0.10 microgram/ml and 0.39 micrograms/ml, respectively. 4. Clinical efficacy was 93.0% in 215 cases (excellent: 136, good: 64, fairly good: 10, poor: 5). CFIX attained a high efficacy in the range of 89.4-95.7% in acute pharyngitis, acute tonsillitis, acute bronchitis and acute pneumonia. 5. Safety was monitored in 224 cases and there were only one case of loose stool and another of diarrhea as side effects. There were no abnormal findings in 31 cases of the laboratory test. In conclusion, it was confirmed that CFIX is excellent and safe in the treatment of the respiratory tract infections.

Physicians investigated a nosocomial diarrhea outbreak among 11 2 year old undernourished children in the nutrition service of the pediatric teaching hospital, Hospital Infantile, in Mexico City, Mexico in April 1988. Health practitioners took at least 2 stool samples from each ill child to be analyzed for Cryptosporidium oocysts. The attack rate stood st 82%. The hospital admitted a malnourished child with chronic diarrhea and pneumonia on March 22. Laboratory tests revealed that he had many Cryptosporidium oocysts and was positive for HIV. Hospital staff did not isolate him. He died on May 9 of Escherichia coli and Candida septicemia. The outbreak ended 1 week later. Laboratory tests detected Cryptosporidium oocysts in 9 cases all of whom were 3-13 months old. Further the symptoms (mean duration 14 days, fever [mean peak 38.6 degrees Celsius, and vomiting] matched those of other reported Cryptosporidium diarrhea outbreaks. The epidemic curve suggested a common source of the outbreak. Since the infants received intravenous feedings or sterilized formula, food and water could not have been the source. The physicians believed the AIDS case was that source. Direct person to person transmission was probably not responsible since each infant had his/her own separate crib. Even though the physicians could not conclusively identify the vehicle of transmission, it was most likely the hands of hospitals staff either directly by touching the infants or by contaminating the nasogastric tubes. After the outbreak, the physicians observed that only 30% of medical personnel indeed washed their hands before caring for an infant. 4 previous studies on nosocomial Cryptosporidium diarrhea outbreaks also reported the source case as immunodeficient, but these studies only included adults.

The authors reviewed all measles cases admitted to the pediatric ward of Goroka Base Hospital in 1989, and also interviewed a sample of measles patients attending the pediatric outpatient department. Measles accounted for 11% of all pediatric admissions and 32% of deaths. The case fatality rate for measles was 17%. Children with nosocomial infections and those of low birthweight were more likely to die. The most common complications of measles were pneumonia and diarrhea, pneumonia being the most common cause of death. 12 cases of subacute sclerosing panencephalitis were admitted during the year (0.5% of pediatric admissions). Measles was underreported because it was frequently omitted from the discharge diagnosis, the emphasis being placed on complications. The majority of children with measles admitted to the ward and seen as outpatients had not been vaccinated. Nosocomial infections could have been reduced if all pediatric admissions ages 6-35 months had been vaccinated on admission. The authors strongly endorse the policy of vaccinating children in Papua New Guinea against measles from the age of 6 months.

Eleven children were identified as being seropositive for HIV-1 at the Ethio-Swedish Children's Hospital, Addis Abeba, Ethiopia between January 1988 and September 1989. The diagnosis was confirmed by both ELISA and Western blot methods performed at the National Research Institute of Health, Special Laboratory for AIDS. The mean age was 2 years and 5 months, with a range of 1 week to 10 years. There were 7 boys and 4 girls. The most common admitting diagnoses were pneumonia (5), gastroenteritis (5), marasmus (5), disseminated tuberculosis (4), and abandonment (3). One patient had extensive facial molluscum contagiosum. Symptoms at admission or during hospitalization included diarrhoea (9), failure to thrive (8), fever (7), and cough (7). Physical findings included hepatosplenomegaly (5), lymphadenopathy (3), and oral candidiasis (2). No patient with an opportunistic infection or radiographic evidence of lymphocytic interstitial pneumonitis (LIP) was identified. Five patients were classified as marasmic and 4 as underweight. Evidence suggestive of encephalopathy (developmental delay and/or microcephaly) was present in 5 patients. The VDRL was non-reactive in the 5 patients in whom it was tested. Nine children were presumed to have acquired the infection by perinatal transmission, though the passive transfer of maternal antibodies or postnatally acquired infection could not be excluded. One child was thought to have acquired the infection by blood transfusion. Three children died during their hospital stay. Paediatric HIV infection exists in Ethiopia; however, these children do not present with characteristic opportunistic infections but with signs and symptoms reflecting the most common paediatric problems seen in the country. Prevention of HIV infection in children entails the prevention of infection in women of childbearing age, counselling of infected women, and effective screening of blood products.
