Hepatitis B antigen in Montréal blood donors: childhood institutionalization as an epidemiologic factor.

In 1971 the Canadian Red Cross blood tranfusion service instituted routine screening for HBAg of all blood donors, using nationwide a standardized counterimmunoelectrophoretic technique. The prevalence of carriers in the Province of Québec is unusually high (0.51%), being 3 to 12 times higher than in the other nine provinces. Among the carriers found in the Montréal area 289 volunteered to be seen by our group for an extensive interview and a series of laboratory tests. There were 243 men and 46 women; their ages ranged from 18 to 55, 90% being less than 40. Twenty-nine were of foreign origin and 260 were born in Canada. The epidemiologic data revealed that the reservoir of HBAg carriers among the blood donors of the Montréal area was found predominantly in the autochthonous population of French origin. Moreover, it appeared that 149 (52%) had lived in institution when they were infants or children: 127 were orphans and had been placed in institutions as newborns or babies, and 22 others had lived in institutions for at least 1 year between the ages of 5 and 10. This was by far the most important single epidemiologic factor that could contribute to the explanation of the abnormally high prevalence of HBAg carriers in the population studied.

Gastroesophageal reflux among severely retarded children.

Of 136 institutionalized severely retarded children, 20 (15%) had recurrent vomiting. Of these 20, 15 had gastroesophageal reflux diagnosed by x-ray examination, acid reflux text, or both. Esophagitis was noted by endoscopy in ten of 14 patients with GER. Four patients were anemic and six had had one or more episodes of aspiration pneumonia in the 12 months prior to study. Reduced basal lower esophageal sphincter pressure was the most common manometric abnormality noted in the patients with GER. Responses of the LES to bethanechol and swallow were normal, as was the basal pressure of the upper esophageal sphincter. Abnormal propagation of esophageal peristalsis was seen in six patients, all of whom had moderate or severe esophagitis. When compared to the nonvomiting retarded patients, the GER patients had significantly lower mental age and higher incidence of scoliosis. Patients with GER who had basal LES pressure less than 10 mm Hg did not improve with medical management. Recurrent vomiting is a common and serious problem in severely retarded children, the organic cause of which can be demonstrated by the application of appropriate investigative techniques.

The prevalence and transmission of hepatitis B virus infection in urban, rural and institutionalized black children of Natal/KwaZulu, South Africa.

The sera of statistically selected urban (805), rural (238) and institutionalized (127) black children were tested for markers of hepatitis B virus (HBV) infection. The age-standardized (6-14 years) prevalence rates of HBs antigenaemia for comparison between urban, rural and institutionalized children were 10%, 18.5% and 25.1% and the HBV exposure rates were 31.4%, 62.1% and 72.0% respectively. In the newborn to six years age group the prevalence rates of HBsAg and HBV exposure were 2.5% and 7.1% for urban children and 53.1% and 70.3% for institutionalized children. Peak prevalences of HBsAg occurred in the 6-8 year age group and were 14.4% and 22.6% in urban and rural children respectively. Hepatitis Be Antigen (HBeAg) was detected in 46.5% and antibodies to hepatitis Be antigen (HBeAb) in 10.0% of all HBsAg positive children. Multiple mechanisms involving horizontal rather than vertical transmission appeared to be important in urban children, with HBV exposure in females being significantly associated with ear-piercing (p less than 0.001) and scarification (p less than 0.05). In addition, HBsAg was detected in 25 of 29 pools of bloodfed mosquitoes caught at the children's institution and was negative in all four pools of unfed mosquitoes, suggesting that these arthropods may also be one factor in the horizontal spread of HBV infection. Familial clustering of HBV infection was suggested by a significantly higher (p less than 0.01) prevalence of HBsAg amongst family contacts of HBsAg positive urban children (17.7%) than in the control groups of family contacts of HBsAb positive children (8%) and children who were negative for all HBV markers (2.4%). The significance and implications of these findings are discussed.

Immunization of institutionalized asthmatic children and patients with psychomotor retardation using live attenuated cold-adapted reassortment influenza A H1N1, H3N2 and B vaccines.

Live attenuated cold-adapted reassortant (CR) influenza virus vaccines were evaluated in institutionalized asthmatic children and severe psychomotor-retarded (SPR) patients. Almost all the vaccinees were seropositive to the vaccine strains before immunization. Trivalent CR vaccine (containing A H1N1 (CR-125), A H3N2 (CR-149) and B (CRB-117)), bivalent CR vaccine (CR-125 and CR-149) and monovalent CRB-117 were inoculated to 19 asthmatic children and 36 and 16 SPR patients, respectively. Overall 49, 22, and 11% of vaccinees were infected by A H1N1, A H3N2 or B vaccine viruses, respectively, as indicated by significant haemagglutination-inhibition (HI) antibody titre rises 4 weeks after inoculation. No severe adverse reactions associated with CR vaccination were observed in the handicapped patients. A nosocomial outbreak of influenza A H1N1 occurred in the ward with asthmatic children, but none of the 19 CR-trivalent vaccinees became infected. However, five of 20 non-vaccinees in the same ward, and ten of 30 vaccinees in another ward that received inactivated split vaccine became infected. The CR vaccines demonstrated significant protective effects against natural exposure to the A H1N1 virus, and were well tolerated and safe when given to patients with bronchial asthma and severe psychomotor retardation.

Growth, morbidity, and mortality in a cohort of institutionalized HIV-1-infected African children.

OBJECTIVE: As a result of the HIV epidemic in Africa, much debate exists on whether institutionalized compared with community-based care provides optimum management of infected children. Previous reports calculated 89% mortality by age 3 years among outpatients in Malawi. No similar data are available for infected children in institutionalized care. We characterized patterns of morbidity and mortality among HIV-1-infected children residing at an orphanage in Nairobi. METHODS: Medical records for 174 children followed over 5 years were reviewed. Mortality was analyzed by Kaplan-Meier methods with adjustment to account for survival in the community before admission. Anthropometric indices were calculated to include mean z scores for weight for length and length for age. Low indices reflected wasting and stunting. Opportunistic infections were documented. RESULTS: Of 174 children, 64 had died. Survival was 70% at age 3 years. Morbidity included recurrent respiratory tract infections, gastroenteritis, parotitis, and lymphoid interstitial pneumonitis. No new cases of tuberculosis disease were noted after admission. Mean z scores for length for age suggested overall stunting (z = -1.65). Wasting was not observed (z = -0.39). CONCLUSION: The optimal form of care for HIV-infected children in resource-poor settings may be the development of similar homes. Absence of tuberculosis disease in long-standing residents may have contributed to improved survival. Stunting in the absence of wasting implied that growth was compromised by opportunistic infections and other cofactors.

Not by bread alone': impact of a structured 90-minute play session on development of children in an orphanage.

BACKGROUND AND OBJECTIVES: In developing countries, caring for the large number of babies in orphanages is very hard work. Whereas the physical needs of most of the children are met, play often gets neglected. Studies have repeatedly shown that babies in such institutionalized settings suffer from severe psychomotor retardation. The aim of this project was to develop an intervention programme of structured play. We hypothesized that such an intervention would result in acceleration of psychosocial development in otherwise healthy institutionalized children. DESIGN: Prospective longitudinal. SETTING: Mother Teresa's Orphanage, run by Missionaries of Charity. SUBJECT AND METHODS: All 30 children in the orphanage aged 6 months-2.5 years, were assessed for their Motor, Mental and Social Quotients, using the Indian adaptation of Bailey's Scale of Infant Development(DASII) and the Vineland's Social Maturity Scale. A structured 'Regime of Play' was then built into the routine of the orphanage. A repeat developmental assessment was performed at the end of 3 months to assess the impact. RESULTS: Out of the original cohort of 30, 19 children were available for post-intervention assessments. The remainder were adopted before their assessments. Their mean Motor Quotient rose from 63.7 to 81.7, mean Mental Quotient rose from 65.8 to 89.6 and the mean Social Quotient rose from 61.9 to 91.3, a gain of 18, 23 and 30 points respectively (p < 0.0001). There was also an overall change in the environment of the orphanage. Children became more active, playful, responsive and independent. Contrary to what caretakers assumed, their workload actually decreased. The responsiveness in the children awakened as a result of play, acted as a positive feedback for caretakers to continue the play sessions. CONCLUSIONS: This study shows that short daily sessions of play can significantly improve the development of children in such institutions. It is vital to remember that children grow 'Not by Bread Alone'.

[Analysis of quantitative information obtained in a field study of affective privation in institutionalized children under 3 years of age].

The aim of this paper is to demonstrate, with the aid of reliable numerical methods, the incidence of the variable, lack of mothering care, in an experimental group (GE) of 94 children under three years of age who had suffered, at least once, separation from mother and had lived for a while in a institution for young children. GE was compared with a control group (GC) of 79 children of similar age and socio-economic status who had never suffered separation from mother. The present paper was based on field research carried out by Julia Ferrari de Prieto in the Refugio Maternal (RM), an institution for young children located in a pediatric hospital in Buenos Aires. From the data gathered, comprising specimen observation, interviews, and results of Brunet and Lezine's Development Test for young children, the AA selected quantitative information--quotient of development (CD)--to make a computational program that proved the following: a) that GC, with a mean CD of 101.61 was really a random sample from a population of children under three years old who had received non-interrupted mothering care; b) that in all the experimental group (GET) the weight of the variable lack of mothering care was found to be very strong, and represented a development shortfall of about 20%; c) that the GET was really a non-homogeneous sample from which was set apart a small sub-group called experimental segregated group (GES) characterized by the short span spent in the RM and whose mean CD of 97.11 was comparatively high; d) that, however, GES was different from GC (Chi-squared test proved the non-dependency of GES and GC samples with a level of significance of 0.05); e) that, therefore, the variable, time when mothering care was lacking was one of very strong weight, even if the period spent in RM was a very short one (7 days for children of age over three months, and 30 days for children of age under three months, at the time of their arrival at the RM). The AA are now carring out an analysis of GES, to be published in a forthcoming paper, in view of the special characteristics of this small group.
