Clinical Pediatrics

A sixth dose of tetanus, diphtheria, acellular pertussis (Tdap) vaccine in adolescents might produce a differing reactogenicity and/or immunogenicity response depending on the composition of the 5 prior doses of DTaP or DT-whole cell pertussis (DTwP) vaccine. Reactions and immune responses following receipt of the Sanofi Pasteur (Adacel) and GlaxoSmithKline (Boostrix) Tdap vaccines were assessed in 229 adolescents. No differences were observed for reactions to either Tdap vaccine regardless of the prior DTaP/DTwP vaccination history. Seroprotective levels and antibody concentrations were comparable regardless of prior DTaP/DTwP vaccine history. A sixth sequential dose of Tdap after 5 doses of DTaP appears safe and immunogenic.

We prospectively quantified disease severity associated with epidemiologic and socioeconomic parameters as well as the clinical factors in 195 previously healthy infants with confirmed respiratory syncytial virus (RSV) infection. Infants were enrolled into three subgroups according to disease severity: outpatients (82 patients), inpatients (100 patients), and intensive care unit patients (13 patients). Epidemiologic parameters such as gestational age, birth weight, chronologic age at presentation, and gender as well as socioeconomic factors such as ethnic origin, family history of asthma, exposure to cigarette smoke, number of family members, presence of pets at home, breast-feeding, and day-care attendance were not found to predict the severity of RSV illness in previously healthy infants. Our results emphasize the complexity of predicting disease severity in previously healthy infants with RSV infection and suggest that other parameters such as host genetic background might explain the clinical variability.

The purpose of the study was to determine the effect of ethyl vinyl chloride vapocoolant spray on pain reported by children undergoing intravenous cannulation. A randomized, double-blinded, placebo-controlled trial was conducted on eligible children between the ages of 9 and 18 years seen in a pediatric emergency department and requiring intravenous cannulation. Informed consent was obtained, and children were randomized to receive ethyl vinyl chloride spray, isopropyl alcohol spray, or no spray (control group). Patient demographics and information pertaining to each intravenous cannulation were recorded. Children indicated the degree of pain associated with intravenous cannulation on a 100-mm visual analog scale (VAS) compared to a baseline pain score of “zero.” Statistical analysis was performed by using Stata version 7. One hundred twenty-seven subjects were enrolled: 37 received ethyl vinyl chloride vapocoolant spray, 48 received isopropyl alcohol spray (placebo), and 42 received no pretreatment. Mean VAS scores for pain experienced during cannulation were 34, 33, and 31 mL for each group, respectively. Ethyl vinyl chloride vapocoolant spray failed to measurably reduce pain associated with intravenous cannulation when compared to those pretreated with isopropyl alcohol spray or receiving no intervention.

This study sought to investigate the efficacy of dextromethorphan (DM), diphenhydramine (DPH), and placebo (PL) for symptoms attributed to upper respiratory infections as determined by children, and to evaluate the concordance of perception of nocturnal symptoms between children and parents. A total of 37 children age 6 to 18 years of age were randomized in a double-masked fashion to receive a single bedtime dose of DM, DPH, or PL. Children found no significant difference in the effect of DM, DPH, or PL for any study outcome, and responses by parents and children were significantly correlated.

Clarithromycin is widely used to treat respiratory tract and superficial skin infections in pediatric and adult populations. Using clinical endpoints and 7-day therapy, we compared the efficacy of clarithromycin 250 mg tablets given twice daily versus clarithromycin 500 mg extendedrelease tablets given once daily in ambulatory children and adolescents 6 to 16 years old. Of the 199 evaluable patients, 124 were infected with group A streptococcal pharyngitis, 39 with sinusitis, 21 with ambulatory pneumonia, and 15 with superficial skin infections. The overall cure rate exceeded 90% for each treatment group. Discontinuation rates and adverse events were 4.5% and 24.6%, respectively.

A model of training pediatricians in mental health diagnosis and intervention was developed to increase the pediatrician's competency in dealing with the increasing number of children with these problems. The model consisted of a pediatric psychiatrist working in collaboration with community pediatricians and training pediatricians in mental health interview and evaluation techniques, recognition and diagnosis of behavioral and mental disorders, and intervention and treatment. Following implementation of this model, the community pediatricians demonstrated an increase in mental health diagnoses in their practices. This model represents one approach in preparing pediatricians to respond to the increasing number of children with mental health and behavioral problems.

The purpose of the study was to examine whether participation in a youth development program positively impacted participants' adult outcomes. Length of time adolescents spent in a comprehensive youth development program was correlated to their adult outcomes and functioning was assessed. All 141 adult past participants of a youth development program were identified. A survey was administered to 97% of the past participants located. School completion, higher education, alcohol and drug use, pregnancy and childbearing, employment, and involvement with the juvenile and adult justice systems were assessed. Degree of involvement in the program (low, medium, and high) was calculated and correlated with outcomes. Of the six areas surveyed, statistically significant findings (p<0.05) were obtained in three: education, employment, and criminal justice. Nonsignificant, but positive, trends were observed in the areas of pregnancy/parenthood and illicit drug use. Best outcomes were achieved with those who participated for at least 201 days.
