Switching to bupropion in fluoxetine-resistant major depressive disorder.

Up to 50% of patients with major depressive disorder (MDD) fail to respond to an antidepressant trial, with most taking a selective serotonin reuptake inhibitor (SSRI) as an initial treatment. Switching to bupropion, for depressed patients not responding to SSRIs, is a popular strategy among clinicians. This study assesses the efficacy of bupropion SR in the management of MDD resistant to a prospective trial of fluoxetine. Twenty-nine patients with MDD refractory to an 8- to 12-week open-trial of fluoxetine were enrolled in an 8-week open-trial of bupropion SR. Both a completer analysis (n = 20) and a modified intent-to-treat analysis (n = 26) were performed to evaluate bupropion SR response rates. Using a completer analysis, seven patients (35.0%) were classified as responders, five (25.0%) partial responders, and eight (40.0%) nonresponders. A modified intent to treat analysis resulted in nine (34.6%) patients classified as responders, eight (30.8%) partial responders, and nine (34.6%) nonresponders. The overall proportion of remitters was 6/20 (30.0%) using a completer analysis and 6/26 (23.1%) using an MITT analysis. Approximately 60% of patients with MDD resistant to a prospective trial of fluoxetine experienced a full or partial response to bupropion SR. Bupropion SR should be considered as a potential treatment for patients who remain depressed despite treatment with SSRIs

Use of lidocaine-prilocaine patch to decrease intramuscular injection pain does not adversely affect the antibody response to diphtheria-tetanus-acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b conjugate and hepatitis B vaccines in infants from birth to six months of age.

BACKGROUND: Topical lidocaine-prilocaine (EMLA) effectively decreases the pain associated with minor procedures including immunization, although the effect on the antibody response to diphtheria-tetanus-acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b conjugate (DTaP-IPV-Hib) and hepatitis B vaccines has not been assessed. OBJECTIVE: To measure the antibody response to DTaP-IPV-Hib and hepatitis B vaccines; to measure pain reduction associated with the use of the lidocaine-prilocaine (EMLA) patch; and to assess safety by comparing adverse reactions. PARTICIPANTS AND SETTING: One hundred nine healthy 6-month-old infants (Part A of study) and 56 healthy infants birth to 2 months of age (Part B of study) undergoing primary immunization with DTaP-IPV-Hib and hepatitis B vaccines in an ambulatory setting. DESIGN AND INTERVENTIONS: Two center, randomized, double blind, controlled trial of EMLA patch or placebo before DTaP-IPV-Hib and hepatitis B immunization. Antibody titers measured at 0 to 2, 6 and 7 months. OUTCOME MEASURES: The primary outcome measure was the antibody response to diphtheria, tetanus, pertussis antigens, Haemophilus influenzae type b and hepatitis B by enzyme immunoassay; and poliovirus 1, 2 and 3 by neutralization. The secondary outcomes were pain scores by the Modified Behavioral Pain Scale and drug- and vaccine-associated adverse events collected with a parent diary and structured questionnaire. RESULTS: There was no difference in the antibody response between the EMLA- and placebo-treated groups as assessed by geometric mean antibody titers, rates of seroconversion or the proportion of participants achieving protective or positive antibody titers postimmunization. At the 6-month visit, EMLA recipients had less pain after immunization (total pain score, 6.75 vs. 7.35; P = 0.005; pain score increase, 3.99 vs. 4.74; P = 0.004) than did placebo recipients. Skin pallor and erythema at the patch application site were more frequently reported after EMLA use. Rates of vaccine-associated adverse events were similar in the two groups. CONCLUSIONS: The EMLA patch has no adverse effect on the antibody response to the vaccine antigens, is effective in reducing pain associated with DTaP-IPV-Hib and hepatitis B immunizations and does not result in any significant or unexpected adverse reactions.

Psychological impact of benign breast biopsy: a longitudinal, comparative study.

The impact of benign breast biopsy (BBB) on distress and perceptions of risk for breast cancer (BC) was examined. Interviews were conducted with 100 women shortly after notification of biopsy results and 4 and 8 months post-BBB. Compared with matched healthy comparison (HC) women without BBB, the BBB group evidenced greater BC-specific distress at baseline. BC-specific distress declined after BBB, remaining elevated relative to the HC group at the 8-month follow-up. Dispositional (optimism, informational coping style), demographic (education), clinical (family history of BC), and cognitive (BC risk perception) variables were associated with baseline levels of BC-specific distress or persistence of distress. Results support the monitoring process model (S. M. Miller, 1995) and the cognitive social health information processing model (S. M. Miller, Y. Shoda, & K. Hurley, 1996).

The role of parent training in treatment of preschoolers with ADDH.

The efficacy of group parent training was assessed in improving compliance and time on task in preschoolers with attention-deficit disorder with hyperactivity. Positive effects were obtained on measures of child compliance, but not on measures of attention. Parental compliance-management skills and overall style of interaction were also positively affected. The use of parent training for early intervention with ADDH children is discussed.

Outcome of parent-mediated treatment of preschoolers with attention deficit disorder with hyperactivity.

Despite the early onset of attention deficit disorder with hyperactivity (ADDH), there is a dearth of treatment studies with preschoolers with this disorder. Forty-six families with ADDH preschoolers were randomly assigned to either an immediate or a delayed group parent training program aimed at improving child compliance. Groups were balanced on demographic variables. Treatment outcome was evaluated by comparing the groups at pre- and posttreatment and 3-month follow-up on measures of parent-child interactions during free play, a compliance task, and parent-supervised activities, as well as on parent-completed Conners Hyperkinesis Index scores. Positive treatment effect was obtained on measures of compliance, parental style of interaction, and management skills. These improvements were maintained at 3-month follow-up. Evaluation of treatment effects on nontargeted child behaviors indicated no generalization.

Vicissitudes of follow-up studies: differential effects of parent training and stimulant medication with hyperactives.

A two-year outcome study of 73 hyperactive children supports both previous short-term studies which suggested that stimulant medication is superior to parent training and long-term studies which found no differences between the two interventions. The discrepancy is discussed in light of complications that inevitably arise in outcome studies and that tend to preclude meaningful outcomes in long-term studies. The development of new research strategies is called for.

Children's drawings of their pain.

Children and adolescents with recurrent migraine headaches or musculo-skeletal pain were asked to draw a picture of their pain and another picture of themselves in pain. The drawings were categorized according to content and color. No differences in content or dominant color of drawings was found for sex and there were no changes with age (5-18 years). Children with recurrent migraine more often drew themselves doing something to relieve their pain, than did children with musculo-skeletal pain. Implications for the use of pain drawings in the treatment of chronic and recurrent pain are discussed.
