Question: Unintentional injuries are the leading cause of death in children, and falls are the most common type of unintentional injury in the US. The incidence of falls from windows, a common cause of death in urban areas, has not been described outside major cities such as New York and Chicago, and rates in urban and suburban areas have not been compared.', 'To estimate the incidence and identify the population at risk for falls from windows among children in Hamilton County, Ohio.', "Retrospective case series identified using Cincinnati Children's Hospital Medical Center (CHMC) Trauma Registry.", 'Hamilton County, Ohio, which has urban and nonurban areas.', 'Children less than 15 years old residing in Hamilton County, Ohio, presenting to CHMC in Cincinnati, Ohio, after a fall from a window between January 1, 1991, and December 31, 1997.', 'Annual incidence by age, race, gender, and residence of those who fell from windows.', 'Over the 7-year study period, 86 (6.3%) of 1,363 falls were from windows. The mortality rate for falls from windows was 4.7%, compared to 0.07% for all other falls presenting to CHMC (P<.0001). Children 0-4 years old had a higher rate of falls than children aged 5-14 (14.6/100,000 vs. 2.0/100,000) (P<.0001). Males were twice as likely to fall as females (P<.016), and black children were three times more likely to fall than non-black children (P<.002). The incidence of falls in the city of Cincinnati was four times that of the non-urban area (P<.0002).

Answer: Does childhood injuries and deaths due to fall from windows?

Question: The biliary cast syndrome (BCS) is a frequent problem following liver transplantation. The pathogenesis of this complication is not well understood. Previous research has demonstrated that the soluble form of MICA (sMICA) is significantly higher in patients with chronic liver disease and hepatocellular carcinoma (HCC) than in healthy volunteers. The aim of this study is to investigate the possible involvement of sMICA in the formation of BCS after liver transplantation.', 'Serum soluble MICA was retrospectively evaluated in pre- and post-transplant sera from 133 consecutive primary liver transplant patients and in sera from 88 healthy volunteers using sandwich ELISA. Normal distribution of serum sMICA was described by the data obtained from healthy population and sMICA concentration that was greater than the upper bound 95% normal range was considered as high levels of sMICA. Patient records were reviewed to identify patients who developed BCS.', 'The results demonstrated that 37.6% of patients with end-stage liver diseases had significantly higher pre-transplant serum sMICA than in healthy population. 34.4% of recipients with post-transplant high levels of sMICA developed BCS. In contrast, 17.3% of patients with post-transplant normal levels of sMICA developed BCS. The risk of BCS development is significantly associated with the presence of post-transplant high levels of sMICA (P=0.0365). Further analysis disclosed that patients with decreased post-transplant sMICA following liver transplantation had a lower incidence rate of BCS than those with remained high levels of sMICA after transplantation (10.5% vs. 38.7%, P=0.0302). Furthermore, log-rank test showed that BCS occurrence was significantly associated with dynamic changes of sMICA among different groups (P=0.0188).

Answer: Are high levels of soluble Major Histocompatibility Complex class I related chain A ( MICA ) associated with biliary cast syndrome after liver transplantation?

Question: Children involved with child welfare systems are at high risk for emotional and behavioral problems. Many children with identified mental health problems do not receive care, especially ethnic/minority children.', 'To examine how patterns of specialty mental health service use among children involved with child welfare vary as a function of the degree of coordination between local child welfare and mental health agencies.', 'Specialty mental health service use for 1 year after contact with child welfare was examined in a nationally representative cohort of children aged 2 to 14 years. Predictors of service use were modeled at the child/family and agency/county levels. Child- and agency-level data were collected between October 15, 1999, and April 30, 2001.', 'Ninety-seven US counties.', 'A total of 2823 child welfare cases (multiple informants) from the National Survey of Child and Adolescent Well-being and agency-level key informants from the participating counties.', 'Specialty mental health service use during the year after contact with the child welfare system.', 'Only 28.3% of children received specialty mental health services during the year, although 42.4% had clinical-level Child Behavior Checklist scores. Out-of-home placement, age, and race/ethnicity were strong predictors of service use rates, even after controlling for Child Behavior Checklist scores. Increased coordination between local child welfare and mental health agencies was associated with stronger relationships between Child Behavior Checklist scores and service use and decreased differences in rates of service use between white and African American children.

Answer:
Do contextual predictors of mental health service use among children open to child welfare?
