Child psychiatrists and paediatricians are faced by a number of disturbed children and adolescents who become a major treatment challenge due to a combination of their dangerous and/or disruptive behaviour and the unavailability of resources. Paediatricians and psychiatrists in one regional health area were questioned about the number of such children and adolescents under 18 years of age seen over a 20 month period. The response rate was 44% (86/194 specialists approached). A total of 72 children and adolescents were identified. For a health district with a total population of 200,000, this represents nearly five children (about one of these identified by paediatricians and one with associated learning disability). The majority of cases were adolescents with chronic problems (over one month's duration) but most cases reported by paediatricians were acute in preadolescents. Conduct disorders, autistic spectrum, and psychotic disorders were the most common clinical problems. Seriously disruptive behaviour had been present in two thirds and marked problems with behaviour that was a physical risk to others and to the self were present in over half and nearly a third of cases respectively. Services had been universally stretched by these children's difficulties. Clinicians thought the needs of these children would have been best met either through psychiatric day hospital type facilities or in combined paediatric/child psychiatric inpatient units.  相似文献

1. The aim of the present study was to determine the effects of prolonged prostaglandin E2 (PGE2) administration on the function of the foetal kidneys and lungs in order to gain a greater understanding of the role played by PGE2 in the control of foetal fluid balance. By studying the effects of PGE2 at two gestational ages, we have also been able to examine the influence of age. 2. We studied the effects of 26 h PGE2 infusion on foetal sheep at a mean (±SEM) of 120.0 ± 0.6 (n= 6) and 139.0 ± 0.8 (n= 4) days of gestation. In both groups, foetal urine production was significantly inhibited throughout the infusion period (P < 0.05). In younger, but not older foetuses, urine production returned to control values within 24 h of ending the infusion (P < 0.05). This PGE2-induced anti-diuresis was associated with foetal hypoxaemia and acidaemia, a reduction in free water clearance and an increase in foetal plasma arginine vasopressin concentrations (P < 0.05). 3. During PGE2 infusions, foetal breathing movements were inhibited, the effect being greater and more sustained in older foetuses (P < 0.05). 4. Infusions of PGE2 led to increased lung liquid production at both ages (P < 0.05); lung liquid volumes were reduced in older foetuses (P < 0.05), but were unchanged in younger foetuses. The reduction in lung liquid volume in older foetuses may have been due to inhibition of foetal breathing. 5. We conclude that increased circulating levels of PGE2 have profound effects on foetal renal and lung function which, if sustained, could compromise foetal lung development and perinatal well-being.  相似文献

The anti-A response in a group B patient accidentally given 1 unit transfusion of A1 blood is described. The antibody response is characterized both with conventional agglutination techniques and with radioimmunoassay using pure group A antigens with different core saccharide structures (type 1, 2, and 4 chains) and class-specific second antibodies. The anti-A titer rose to a maximum Days 11 to 14 after the incompatible transfusion. The antibodies involved were mainly of the IgG and IgA types, while the IgM response was moderate. The IgA antibodies seemed to be nonselective with respect to group A antigen type, while the IgG antibodies showed a specificity against type 2 chain group A antigens.  相似文献

Magnetic resonance (MR) imaging of the hip has been useful in the examination of patients for the presence of avascular necrosis (AVN). In the detection of AVN, MR imaging is more sensitive than computed tomography or nuclear scintigraphy. This study assessed the usefulness of MR imaging in the differentiation of AVN from other hip diseases. Twenty-two cases of non-AVN hip disease were matched with 23 biopsy-proved cases of AVN and ten normal controls. MR images were rated in a blinded manner by five experienced radiologists, and receiver operating characteristic (ROC) analysis was performed on the data. In the discrimination of AVN from other hip diseases or from normality, the A(z) value (the area under the ROC curve) was 98.6. With a specificity of 98%, MR imaging was 97% sensitive in the differentiation of AVN from normality, 85% sensitive in the differentiation of AVN from non-AVN disease, and 91% sensitive in the differentiation of AVN from both conditions. MR imaging may therefore help discriminate between AVN and other hip diseases.  相似文献

The social adjustment of 45 young adult renal patients who commenced treatment for end stage renal disease (ESRD) as children and of 48 age and sex matched controls were compared. Renal patients were less socially mature than controls. More lived with their parents, fewer had an intimate relationship outside the family, they had fewer school qualifications, and there was more unemployment among them. The majority, however, were in employment and the level of subjective stress and support derived from most of these areas was comparable in renal patients and in controls. Having a close relationship with a member of the opposite sex was the only domain in which renal patients reported more stress than controls. Early start of illness and current health problems were associated with poorer social outcome. A lifelong history of ESRD leads to suboptimal or delayed social functioning on conventional indicators. However this does not lead to increased overall distress in the patients about their social circumstances and quality of life does not appear to be substantially impaired.  相似文献

As a response to the need for more information about health problems in poor urban communities, a health survey was conducted in Rocinha, the largest squatter settlement, or favela, in Rio de Janeiro. A fifteen-day recall period was used to measure gastro-intestinal disorders, acute respiratory infections, and infections of the throat/ears/eyes in 600 children under 5 years of age. The respective prevalence of the three categories was 44, 79, and 14 per cent. Taking only severe episodes into account, the prevalence was 4, 12, and 2.5 per cent, respectively. Risk factors, such as household income and environmental conditions (socioeconomic status), migration status, maternal stress, magnitude of separation between child and mother, and age of child, are examined and implications of positive associations are discussed.  相似文献
