Nutritional supplementation, psychosocial stimulation, and growth of stunted children: the Jamaican study

The benefits of nutritional supplementation, with or without psychosocial stimulation, on the growth of stunted children were evaluated. Children aged 9-24 mo with lengths less than -2 SD of the National Center for Health Statistics references (n = 129) were randomly assigned to four groups: control, nutritional supplementation, stimulation, and both interventions. A fifth group with lengths greater than -1 SD was also enrolled. Length, weight, head and arm circumferences, and triceps and subscapular skinfold thicknesses were measured on enrollment and 6 and 12 mo later. Multiple-regression analysis was used to determine the effects of the interventions in which age, sex, initial status, initial dietary intake, and several socioeconomic variables were controlled for. Stimulation had no effect on growth and there was no interaction between the interventions. After 12 mo supplemented children had significantly increased length, weight, and head circumference (all P less than 0.01). The effects of supplementation were not cumulative but occurred in the first 6 mo.     

Peripheral pulmonary artery aneurysm in a patient with limited respiratory reserve: controlled resection using cardiopulmonary bypass

Pulmonary artery aneurysms are rare lesions for which operative management is not frequently undertaken. When operation is indicated, central lesions involving the pulmonary trunk, right main pulmonary artery, or left main pulmonary artery are repaired using cardiopulmonary bypass. Peripheral aneurysms in segmental intrapulmonary arteries have been managed most frequently by lobectomy, but occasionally by aneurysmectomy and pulmonary arterial repair. We used cardiopulmonary bypass for peripheral pulmonary aneurysmectomy in a patient with limited respiratory reserve because he had undergone prior contralateral bilobectomy; this allowed controlled resection while preserving a maximal amount of pulmonary parenchyma.     

Toxocariasis: a serological survey of blood donors in the Australian Capital Territory together with observations on the risks of infection

The sera from 660 healthy blood donors from Canberra were tested for antibodies to Toxocara canis by the ELISA test. The results were compared with those from patients with suspected or confirmed visceral larva migrans or ocular toxocariasis. Over 7% of Canberra sera showed elevated levels of antibody reacting with T. canis antigen. Sera from patients resident in Australia with other helminth parasites did not cross-react with T. canis antigen in our tests. However, studies of sera collected in several tropical countries with other parasitic infection, show that cross-reactions with other parasites are possible. The use of purified glycoprotein antigen does not alter the possibility of cross-reaction. Observations and experiments show that people in Canberra may be exposed to the infective eggs of T. canis.     

Academia Eurasiana Neurochirurgica Brain Death

Conclusions Brain death (or cerebral death) means definitive cessation of all neural functions above the spinal cord, thus implying the irreversible loss of all cerebral and brain stem functions.Spinal cord activity may persist after brain death-priapism, persistence of myotatic reflexes- for a few minutes and this spinal activity may be responsible for coarse limb movements after life-support machines have been turned off.The preservation of these spinal reflexes reinforces the advice to allow only responsible doctors to assist at the declaration of death of the patient.     

High risk factors for rehospitalization within six months

Objective. 1. To identify risk factors associated with psychiatric rehospitalization within six months, using global clinical assessments and demographic information and; 2. To determine if risk factors for a hospital in a rural region are similar to those reported for urban hospitals. Method. The setting was a psychiatric unit within a general hospital. All adult admissions for one year were assigned scores on the North Carolina Functional Assessment Scale (NCFAS) and the Global Assessment of Functioning (GAF) scale. Patients were interviewed six months after discharge to determine if they had been rehospitalized and to assign new NCFAS and GAF scores. Results. Significant risk of rehospitalization was predicted by: 1. NCFAS score >90; 2. history of prior hospitalization; 3. nursing home residence; 4. referral from a small community hospital and; 5. non-compliance with outpatient appointments. Conclusions. Global assessments and demographic information collected during an index admission can generate factors to identify patients at risk for rehospitalization within six months. History of prior admissions and non-compliance with outpatient treatment, reported as risk factors in urban settings, were found also to be risk factors in a rural region.He was formerly Assistant Professor, Center for Health Sciences Statistics, East Carolina University School of Medicine.
