RESUMEN
OBJECTIVE: To determine if early measurement of end-tidal carbon dioxide (ETCO2) in nonintubated patients triaged to a level 1 trauma center has utility in ruling out severe injury. METHODS: We performed a prospective cohort study of adult patients triaged to our urban, academic, level 1 trauma center. Included patients had ETCO2 measured within 30 minutes of arrival. Chart review was performed on enrolled patients to identify severe injury defined by: admission to an intensive care unit, need for an invasive procedure, blood product transfusion, acute blood loss anemia, and acute clinically significant finding on computed tomographic scan. RESULTS: Of 170 patients enrolled, 115 met the outcome of no severe injury. Mean ETCO2 for patients without and with severe injury was 33.1 mm Hg (SD, 5.8) and 30.3 mm Hg (SD, 6.7), respectively. This difference reached statistical significance (P=.05), but did not demonstrate added clinical utility when combined with Glasgow Coma Scale, systolic blood pressure, and age in predicting the primary outcome (area under curve, 0.70 with ETCO2 vs area under curve, 0.68 without ETCO2, P=.5). Patients with ETCO2 ≤30 mm Hg were found to be older, more likely to require intensive care unit admission or emergency operative intervention, develop acute blood loss anemia, and have an acute finding on computed tomography than patients with a higher ETCO2. CONCLUSION: End-tidal carbon dioxide cannot be used to rule out severe injury in patients meeting criteria for trauma center care. The ETCO2 ≤30 mm Hg may be associated with increased risk of traumatic severe injury.

BACKGROUND: This study examines the relationship among psychosocial factors, behavioral risks for abnormal cervical cytology, and abnormal cervical cytology. METHODS: A self-administered questionnaire was used to measure perceived stress, discrimination, lifetime stressful events, optimism, social support, and psychological state. Women with normal Pap smears attending a primary care clinic and women attending a colposcopy clinic because of an abnormal Pap smear were eligible. The scores between the two groups were compared. RESULTS: A total of 265 women participated in the study. There were no significant relationships between psychosocial factors and cervical cytology status. In a regression model, age (B = -0.057, p = 0.001) was predictive of having abnormal cervical cytology. Smoking was correlated with an increased family Apgar score (p = 0.021), Perceived Stress Scale (PSS) score (p = 0.049), and Revised Life Stressor Checklist score (p < 0.001). A higher mean number of lifetime male partners was related to increased family Apgar score (p = 0.012), Revised Life Stressor Checklist score (p < 0.001), and major event discrimination (p < 0.001). Earlier age at coitarche was associated with increased family Apgar score (p < 0.001). CONCLUSIONS: These results do not support that psychosocial factors play a role in the risk of developing abnormal cervical cytology. Behavioral risks for developing abnormal cervical cytology are associated with life stressors, family function, and perceived discrimination.

OBJECTIVE: The aim of this study was to conduct an initial evaluation of the efficacy of atomoxetine for attention-deficit/hyperactivity disorder (ADHD) symptoms in children with pervasive developmental disorders (PDDs). METHOD: Children with PDDs and a nonverbal IQ of >or=70 received atomoxetine (target dose 1.2-1.4 mg/kg/day) during the course of an 8-week, open-label, prospective study. Standardized assessments of efficacy and tolerability were collected at regular intervals during the trial. RESULTS: Sixteen children and adolescents (mean age 7.7 +/- 2.2 years, age range 6-14 years) with autistic disorder (n = 7), Asperger's disorder (n = 7), or PDD not otherwise specified (n = 2) received atomoxetine (mean dose 1.2 +/- 0.3 mg/kg/day). Twelve participants (75%) were rated as "much" or "very much improved" on the Clinical Global Impressions-Improvement scale. The most significant improvement was seen in the area of ADHD symptoms as measured by the SNAP-IV and Aberrant Behavior Checklist (effect size = 1.0-1.9). Improvements of lesser magnitude (effect size = 0.4-1.1) were seen in irritability, social withdrawal, stereotypy, and repetitive speech. There were no significant changes on the Conners' Continuous Performance Test. Atomoxetine was well tolerated with the exception of 2 participants (13 %) who stopped medication due to irritability. Weight decreased by a mean of 0.8 kg during the 8-week trial. CONCLUSIONS: Placebo-controlled studies are indicated to determine atomoxetine's efficacy for ADHD symptoms in PDDs.
