Disease in children infected with HIV in Abidjan, Côte d'Ivoire.

OBJECTIVE: To document the range of disease in African children infected with HIV. DESIGN: Necropsy results in consecutive children aged 1 month or more who were HIV positive and in children who were HIV negative for comparison; IgA western blots on serum samples from children under 2 years of age who were positive for HIV-1 to test the validity of routine HIV serology. SETTING: Largest hospital in Abidjan, Côte d'Ivoire. SUBJECTS: 78 children who were HIV positive and 77 children who were HIV negative on whom a necropsy was performed; their median ages at death were 18 and 21 months respectively. 36 HIV positive children and 29 HIV negative children were 1-14 months old; 42 HIV positive and 48 HIV negative children were > or = 15 months old. MAIN OUTCOME MEASURES: Cause of death and prevalence of diseases confirmed pathologically. RESULTS: Respiratory tract infections were more common in HIV positive than in HIV negative children (73 (94%) v 52 (68%); P < 0.05), and were aetiologically heterogeneous. Pneumocystis carinii pneumonia was found in 11 out of 36 (31%) HIV positive children aged < 15 months, but in no HIV negative children. Among older children measles was more common in HIV positive children (8/42 (19%) v 2/48 (4%); P < 0.06). Pyogenic meningitis was present in similar proportions of HIV positive and HIV negative children aged < 15 months (7/36 (19%) and 7/29 (24%)). In HIV positive children tuberculosis (1/78), lymphocytic interstitial pneumonitis (1/78), and HIV encephalitis (2/78) were rare. CONCLUSIONS: There is greater overlap between diseases associated with HIV infection and other common health problems in African children than there is in adults. Compared with adults, HIV positive children had a high prevalence of P carinii pneumonia and a low prevalence of tuberculosis. Measles, but not malaria, was associated with HIV infection.

Clinical spectrum of human immunodeficiency virus disease in children in a west African city. Project RETRO-CI.

OBJECTIVES: To determine the prevalence of HIV infection in children and to compare diagnostic syndromes and outcomes in HIV-positive and HIV-negative children. METHODS: Consecutive children hospitalized in Abidjan's three university hospitals were examined, tested for HIV infection and followed to discharge. Admission or discharge diagnoses and outcome (survived or died) were compared in HIV-positive and HIV-negative children. RESULTS: The prevalence of HIV infection in the 4480 children hospitalized for the first time was 8.2%; the highest age-specific rate (11.2%) was in children ages 15 to 23 months. Six clinical syndromes accounted for more than 80% of admissions in HIV-positive and -negative children (all ages combined): respiratory infection; malnutrition; malaria; anemia; diarrhea; and meningitis. The dominant syndromic diagnoses in HIV-positive children were respiratory infection (26.1%) and malnutrition (25.8%); in HIV-negative children they were malaria (30.4%) and respiratory infection (19.1%). The overall mortality rate in HIV-positive children was 20.8%, compared with 8.7% in HIV-negative children (relative risk, 2.4; 95% confidence interval, 1.9 to 3.1); the highest death rate (28.1%) was in children younger than 15 months. CONCLUSIONS: Clinical syndromes associated with HIV infection in African children are difficult to recognize without access to HIV serology. Respiratory infection and malnutrition were the dominant clinical syndromes in HIV-positive children in Abidjan. Greater overlap exists between the clinical presentations of HIV-associated disease and other common health problems in African children than in adults.

[Etiology of splenomegaly in children in the tropics. 178 cases reviewed at the university hospital center of Abidjan-Cocody (Ivory Coast)].

Discovery of an enlarged spleen in a child requires steps to identify the etiology. One hundred and seventy-eight patients seen over a four-year period (1985-1988) at the Cocody Teaching Hospital were reviewed. The incidence of splenic enlargement among pediatric inpatients was 1.6%. Males (n = 106) were more often affected than females (n = 72). Slightly over half the children (54.49%) were 0 to 5 years of age. The main clinical presenting features were fever (90%), anemia (72%), a decline in general health (36.50%), enlargement of the liver (33.50%), jaundice (26.50%), and enlarged lymph nodes (7%). Type II of Hackett's classification accounted for most cases (61.80%), followed by Type III (14%). Main etiologies included malaria (53%), salmonella infections (15%), sickle cell anemia (14%), schistosomiasis (9%), AIDS (3%), and thalassemia (2%). Malignancies (leukemia, lymphoma) were relatively infrequent. More than one etiology was found in 13 cases. The distribution of etiologies by age group was determined and a strategy for investigating children with splenic enlargement in tropical countries was developed.

Silent myocardial ischemia during Holter monitoring in ischemic heart disease.

The purpose of this study was to investigate the frequency and characteristics of silent myocardial ischemia in patients with proven ischemic heart disease using ambulatory ECG monitoring, and to clarify possible mechanisms for the absence of symptoms during these attacks. A total of 182 patients, including 78 patients with stable effort angina (EA), 12 with unstable angina (UA), and 92 with prior myocardial infarction (MI), were examined. During daily activities, 43% and 56% of all transient ST-segment depression observed was asymptomatic in patients with EA and MI, respectively. In addition, 74% of all ischemic episodes were asymptomatic in patients with UA. In patients with EA, 35% exhibited both symptomatic and asymptomatic attacks, and the duration and magnitude of ST-segment depression were greater for symptomatic attacks than for asymptomatic attacks. On the other hand, in patients with MI, 55% had only asymptomatic attacks. When asymptomatic episodes in patients who had only asymptomatic attacks were compared with symptomatic episodes in patients who had only symptomatic attacks, asymptomatic episodes tended to be associated with a greater magnitude of ST depression. They were also significantly longer in duration than the symptomatic episodes. All patients with UA had both symptomatic and asymptomatic episodes, and the magnitude and duration were significantly greater during the former. These results lead us to conclude that: (1) silent myocardial ischemia is observed frequently in patients with EA and MI during daily activities. In particular, patients with MI tend to have more severe silent ischemia. (2) In patients with EA and UA, the severity of ischemia is a fundamental factor in determining the presence or absence of pain during an ischemic attack.(ABSTRACT TRUNCATED AT 250 WORDS)

Geographic variations in elderly hospital and surgical discharge rates, New York State.

Hospital and surgical discharges for 1981, as recorded by the uniform hospital discharge data of New York State, were aggregated by county of residence and converted into age-sex adjusted rates. Elderly hospital discharge and surgery rates in New York State, 1981, varied 2.4- and 2-fold, respectively. Discharge rates of elderly with specific surgical procedures showed even greater variation. However, proportions of highly complex and non-elective procedures performed on the elderly were similar in counties with high and low surgical rates. A multiple regression model consisting of independent dimensions of county demographic and medical resources characteristics plus a proxy variable for surgical practice styles was applied to hospital and surgery rates. Variations in elderly surgical discharge rates were found to be related to the supply of medical resources and to surgical practice styles.

5-fluorouracil sensitivity and dihydropyrimidine dehydrogenase activity in advanced gastric cancer.

BACKGROUND: Dihydropyrimidine dehydrogenase (DPD) is the rate-limiting enzyme of 5-fluorouracil (5-FU) catabolism. Several studies have demonstrated the clinical importance of DPD in cancer patients, suggesting that the efficacy of 5-FU may be related to DPD activity in tumor tissue. In the present study, DPD activity and chemosensitivity to 5-FU were evaluated in advanced gastric cancer. MATERIALS AND METHODS: Thirty-four gastric cancers from 32 patients were studied and chemosensitivity to 5-FU was evaluated by histoculture drug response assay. RESULTS AND CONCLUSION: DPD activity and tumor inhibition of 5-FU among all cases showed no significant correlation, but among 14 histologically differentiated cases significant correlation was observed. DPD activity may be useful in determining the 5-FU sensitivity of differentiated gastric cancer.

[Long-lasting remission of Burkitt's disease in African children. Apropos of 6 cases].

Long complete remission in six cases of Burkitt's lymphoma in African children is reported. Complete remissions over eighteen months free of disease are considered as recovery because relapses are rare after this period. These remissions are obtained as well as in stage I and stages III-IV. If classic chemotherapy (cyclophosphamide and methotrexate) is effective, aggressive chemotherapy with several antimitotic drugs is recommended in the poor prognosis forms and relapses. Central nervous system chemoprophylaxis, radiation and maintenance chemotherapy are discussed. Prognosis improvement of Burkitt's lymphoma in African children needs early diagnosis and more aggressive treatment with less damage.

Significance of para-aortic lymph node dissection in patients with advanced and recurrent gastric cancer.

Among 243 patients who underwent radical gastrectomy for advanced gastric cancer, 19 patients underwent radical gastrectomy with extended lymphadenectomy including cancer-positive para-aortic lymph nodes. Their prognosis was unexpectedly good, with a mean postoperative survival time of 24.1 months and a 2-year-survival rate of 42.4 percent. Another 4 patients developed para-aortic lymph node recurrence detected by computed tomographic scan during a follow-up examination. These 4 patients were treated with macroscopic curative dissection of the para-aortic lymph nodes. Although 2 of the 4 patients died within 6 months after re-operation, the prognosis of the other two patients was rather good when treated with active combination chemotherapy consisting of 5-fluorouracil, adriamycin and cisplatin. Dissection of para-aortic lymph nodes is considered of valuable in the treatment of advanced gastric cancer, and dissection of the para-aortic lymph node recurrence may also be valid when combined with potent chemotherapy.
