Child and family factors that ameliorate risk between 4 and 13 years of age.

Protective processes in at-risk children between 4 and 13 years of age were examined in a longitudinal study. A multiple risk index was used at 4 years to identify 50 high-risk children and 102 who were at low risk. Cognitive and social-emotional status were measured at each time point. The following indicators of protective processes were related to positive change in cognitive and/or social-emotional function in the high-risk children between 4 and 13 years: mother-child interaction; child perceived competence, locus of control, life events, and social support; and maternal parenting values, social support, depression, and expressed emotion. Many of these factors were also related to improvement in the low-risk children. Some variables showed an interaction effect, where impact was substantially higher in the high-risk group compared with the low-risk group. The utility of multiple risk constructs and process oriented approaches to protective factors are discussed.     

Physical and Sexual Abuse and their Relation to Psychiatric Disorder and Suicidal Behavior among Adolescents who are Psychiatrically Hospitalized

Adolescents who were psychiatrically hospitalized ( N = 105) were classified as sexually abused, physically abused, both sexually and physically abused, or not abused, and studied to determine the prevalence of suicidal behavior and psychiatric disorders. Self-reports of hopelessness, depression, coping, and self-concept were also examined. No difference in suicidal behavior or psychiatric disorder, based on abuse history, was found, with one exception. Adolescents who were sexually abused, particularly those who experienced the most severe sexual abuse, used negative coping strategies more often than those not sexually abused. Findings suggest that symptomatology of adolescents who are psychiatrically hospitalized does not differ markedly based on history of abuse.     

Is major depressive disorder in adolescence a distinct diagnostic entity?

The concept of major depressive disorder in childhood and adolescence is reviewed and it is suggested that contemporary enthusiasm for this diagnosis may have outrun the evidence that it is a distinct categorical entity. To test the hypothesis that major depression is not a qualitatively distinct disorder in adolescence, but rather a continuously distributed, noncategorical syndrome, the behavioral rating scales (CBCL-P) of 216 hospitalized adolescent patients were analyzed first by principal components analysis and then by cluster analysis. Three behavioral syndromes were isolated by principal components analysis. Of three groups of patients identified by a subsequent cluster analysis, one was consistent with the concept of a categorically distinct "nuclear" depression. However, a noncategorical continuously distributed depressive syndrome appears to affect a larger number of patients in this age group, and the "nuclear" disorder may be less prevalent than is currently assumed. One explanation of these findings would combine a categorical model of nuclear depression with a dimensional model of dysthymia.     

New non-cocaine-containing topical anesthetics compared with tetracaine-adrenaline-cocaine during repair of lacerations

OBJECTIVE: To compare the effectiveness of three new topical anesthetics that do not contain cocaine (prilocaine-phenylephrine, tetracaine-phenylephrine [tetraphen], and tetracaine-lidocaine-phenylephrine) to that of tetracaine-adrenaline-cocaine (TAC) during laceration repair in children. DESIGN: Prospective, randomized, double-blind clinical trial. SETTING: The emergency department of an urban children's hospital. PARTICIPANTS: Children 1 year of age or older with a laceration /= 5 years of age using a visual analogue scale (VAS). Suture technicians, research assistants, and parents also scored pain using a seven-point Likert scale. In addition, suture technicians completed an anesthetic effectiveness scale. RESULTS: There was consistently no difference demonstrated between the effectiveness of tetraphen and that of TAC for each outcome measure of each observer group. A statistically significant difference was seen among anesthetics when comparing VAS and Likert scale scores of suture technicians and Likert scale scores of research assistants. Based on post hoc analyses, these statistically significant differences were between TAC and prilocaine-phenylephrine (suture technician VAS and Likert scale) and between TAC and tetracaine-lidocaine-phenyl-ephrine (suture technician Likert scale), but not between TAC and tetraphen. When power analyses were performed using alpha = 0.05 and beta = 0.20, it was possible to detect a difference of 1.2 VAS units for each of the observer groups. Based on anesthetic effectiveness scale scores, the three new topical preparations collectively performed significantly better on the face and scalp than on the extremities (relative risk = 1.83; 95% confidence interval 1.20 < relative risk < 2.79). CONCLUSION: This study demonstrated the effectiveness and safety of three new non-cocaine-containing topical anesthetics. Consistently, there was no statistical difference demonstrated between the effectiveness of tetraphen and that of TAC for each outcome measure of each observer group. Tetraphen offers an effective alternative to TAC during laceration repair in children.     

Comparison of serum and plasma measurements of Müllerian inhibiting substance

The authors sought to determine whether measurement of plasma Müllerian inhibiting substance (MIS) is a suitable substitute for measurement of serum MIS. Eighteen samples of serum and plasma were examined that were drawn simultaneously. Levels of MIS were measured with an ELISA kit, and plasma levels were studied in parallel to serum samples. A 98.5% correlation was found between serum and plasma MIS values.
