A homozygous mucosa-associated lymphoid tissue 1 (MALT1) mutation in a family with combined immunodeficiency.

Background: Combined immunodeficiency (CID) is characterized by severe recurrent infections with normal numbers of T and B lymphocytes but with deficient cellular and humoral immunity. Most cases are sporadic, but autosomal recessive inheritance has been described. In most cases, the cause of CID remains unknown.

Anticipatory guidance and early child development: pediatrician advice, parent behaviors, and unmet needs as reported by parents from different backgrounds.

Anticipatory guidance is acknowledged as an important aspect of pediatric practice, and research shows that parents expect and value the information and advice they receive from their pediatric health care providers. This study surveyed 373 parents (88% mothers) of infants in waiting rooms of diverse pediatric practices in Memphis,Tennessee, about their recall of anticipatory guidance received, unmet needs for anticipatory guidance, preferences for sources of information, and activities to promote healthy development. Most parents recalled specific guidance received (diet, communication, and discipline being the most common), and unmet needs (discipline and development being among the most common).

Prevalence and costs of acute and chronic potentially avoidable pediatric hospitalizations in Tennessee.

Background: Potentially avoidable pediatric hospitalizations (PAPH) can now be identified using an analytical tool developed by the federal Agency for Healthcare Research and Quality (AHRQ). We apply this new tool to Tennessee inpatient discharge records for 2005 to determine the prevalence of PAPH and analyze the variation patterns of PAPH across racial, gender, and insurance status lines.

Methods: Retrospective analysis of administrative data based on the UB-92 claims forms submitted by all short-term acute-care hospitals in Tennessee for 2005.

Variations in costs for the care of low-birth-weight infants among academic hospitals.

Objectives: To determine the relative role that academic hospitals (AHs) play in providing neonatal care for low-birth-weight infants within a single state and to determine if there are variations in inpatient costs for neonatal services among AHs.

Design: Retrospective analysis of hospital costs for low-birth-weight infants.

Setting: Cases were identified using 2003-2005 data from the Tennessee Hospital Discharge Data System.

Is environmental tobacco smoke exposure a risk factor for acute gastroenteritis in young children?

Because passive smoke exposure has not been previously linked to diarrhea diseases in children, it was hypothesized that very young children exposed to environmental tobacco smoke (ETS) exposure at home would also be more likely to develop infectious gastroenteritis (GE) than their unexposed counterparts. During 1-year period, 260 children 36 months and younger were prospectively followed up in a private pediatric practice in a southern community in the United States. Multiple logistic regression analysis showed that ETS was strongly predictive of acute GE in the univariate analysis (P = .

Potentially avoidable pediatric hospitalizations as defined by the Agency for Healthcare Research and Quality: what do they tell us about disparities in child health?

This study was conducted to determine if the Agency for Healthcare Research and Quality's newly established pediatric quality monitors, which measure potentially avoidable hospitalizations, are useful in detecting disparities in health care delivery. Data for all hospital discharges in Tennessee in 2002 were evaluated for the 5 pediatric discharge monitors identified by the Agency for Healthcare Research and Quality. These diagnoses were asthma, short-term complications of diabetes, gastroenteritis, urinary tract infection, and perforated appendix.

Do first years really last a lifetime?

Multiple early childhood intervention programs have been introduced to provide at-risk children with a better start in life. This is due to the recognition that early childhood experiences, both positive and negative, can affect the physical, mental, behavioral, and economic well-being of the child. A few of these programs have evaluated long-term outcomes and have demonstrated that the effects of interventions may still be apparent years after the intervention.

Black/white differential use of health services by young children in a rural Mississippi community.

Background And Objectives: Use of health services in rural communities has not been well studied. We explored how black and white children used health services in a rural Mississippi community.

Methods: Data were prospectively collected for 396 children attending a private practice to determine if race was associated with the use of health services in this community.

Environmental tobacco smoke exposure: prevalence and mechanisms of causation of infections in children.

Background And Objectives: Environmental tobacco smoke (ETS) exposure is probably one of the most important public health hazards in our community. Our aim with this article is to (1) review the prevalence of ETS exposure in the United States and how this prevalence is often measured in practice and (2) summarize current thinking concerning the mechanism by which this exposure may cause infections in young children.

Methods: We conducted a Medline search to obtain data published mainly in peer-reviewed journals.
