Neurocognitive functioning over the course of trauma-focused psychotherapy for PTSD: Changes in verbal memory and executive functioning.

OBJECTIVES: Individuals with post-traumatic stress disorder (PTSD) have neurocognitive deficits in verbal memory and executive functioning. In this study, we examined whether memory and executive functioning changed over the course of treatment and which clinical variables were associated with change. DESIGN: Neuropsychological assessments were administered at baseline and endpoint of a randomized controlled trial as secondary outcome. METHODS: Trauma survivors (n = 88) diagnosed with PTSD received trauma-focused psychotherapy within a 17-week randomized controlled trial. Neuropsychological tests were the California Verbal Learning Test, Rivermead Behavioural Memory Test, Stroop Color Word Test, and Trail Making Test. RESULTS: Significant, small- to medium-sized improvements in verbal memory, information processing speed, and executive functioning were found after trauma-focused psychotherapy (Cohen's d 0.16-0.68). Greater PTSD symptom decrease was significantly related to better post-treatment neurocognitive performance (all p < .005). Patients with comorbid depression improved more than patients with PTSD alone on interference tasks (p < .01). No differences emerged between treatment conditions and between patients on serotonergic antidepressants and those who were not. CONCLUSIONS: This study suggests that neurocognitive deficits in PTSD can improve over the course of trauma-focused psychotherapy and are therefore at least partly reversible. Improvements over treatment are in line with previous neuropsychological and neuroimaging studies and effect sizes exceed those of practice effects. Future research should determine whether these changes translate into improved functioning in the daily lives of the patients. PRACTITIONER POINTS: Patients with PTSD have difficulties performing verbal memory tasks (e.g., remembering a grocery list, recall of a story) and executive functioning tasks (e.g., shifting attention between two tasks, ignoring irrelevant information to complete a task). Verbal memory, information processing speed, and executive functioning significantly improved in patients with post-traumatic stress disorder over the course of trauma-focused psychotherapy. Improvements were equal in size for two different trauma-focused psychotherapies (Eye movement desensitization and reprocessing therapy and brief eclectic psychotherapy for PTSD). Medium-sized effects were found for recall of a story, whereas effects in other aspects of verbal memory, information processing speed, and executive functioning were small-sized. No causal attributions can be made because we could not include a control group without treatment for ethical reasons. Findings may be more reflective of patients who completed treatment than patients who prematurely dropped out as completers were overrepresented in our sample.

Functional nonretentive fecal incontinence: do enemas help?

OBJECTIVE: To assess the current treatment of functional nonretentive fecal incontinence, which consists of education, toilet training, and positive motivation. STUDY DESIGN: Patients, age 6 years and older, referred for fecal incontinence (FI) and diagnosed with functional nonretentive fecal incontinence were eligible candidates. Seventy-one children (76% boys, median age 9.3 years) were randomized to receive conventional therapy (control group) or conventional therapy in addition to daily enemas during 2 weeks. Treatment success was defined as <2 episodes of FI/month without use of enemas. RESULTS: At intake, the median FI frequency was 6.1 per week, whereas the median defecation frequency was 7.0 per week. At the end of the treatment period, the median number of FI episodes was significantly decreased in both groups: from 7.0 (IQR 4.0-11.5) to 1.0 (IQR 0.5-2.0) in the intervention group and from 6.0 (IQR 4.0-10) to 2.0 (IQR 0.5-3.5) in the control group. No statistical difference was found between the groups at the end of the treatment period (P = .08) nor during additional follow-up (average success rate 17% for both groups, P = .99). CONCLUSION: Temporarily application of additional rectal enemas did not significantly improve treatment success compared with conventional therapy alone.

Gut-directed hypnotherapy for functional abdominal pain or irritable bowel syndrome in children: a systematic review.

OBJECTIVES: Gut directed hypnotherapy (HT) is shown to be effective in adult functional abdominal pain (FAP) and irritable bowel syndrome (IBS) patients. We performed a systematic review to assess efficacy of HT in paediatric FAP/IBS patients. METHODS: We searched Medline, Embase, PsychINFO, Cumulative Index to Nursing and Allied Health Literature databases and Cochrane Central Register of Controlled Trials for randomised controlled trials (RCT) in children with FAP or IBS, investigating efficacy of HT on the following outcomes: abdominal pain scores, quality of life, costs and school absenteeism. RESULTS: Three RCT comparing HT to a control treatment were included with sample sizes ranging from 22 to 52 children. We refrained from statistical pooling because of low number of studies and many differences in design and outcomes. Two studies examined HT performed by a therapist, one examined HT through self-exercises on audio CD. All trials showed statistically significantly greater improvement in abdominal pain scores among children receiving HT. One trial reported beneficial effects sustained after 1 year of follow-up. One trial reported statistically significant improvement in quality of life in the HT group. Two trials reported significant reductions in school absenteeism after HT. CONCLUSIONS: Therapeutic effects of HT seem superior to standard medical care in children with FAP or IBS. It remains difficult to quantify exact benefits. The need for more high quality research is evident.

Triage of frail elderly with reduced exercise tolerance in primary care (TREE). A clustered randomized diagnostic study.

BACKGROUND: Exercise reduced tolerance and breathlessness are common in the elderly and can result in substantial loss in functionality and health related quality of life. Heart failure (HF) and chronic obstructive pulmonary disease (COPD) are common underlying causes, but can be difficult to disentangle due to overlap in symptomatology. In addition, other potential causes such as obesity, anaemia, renal dysfunction and thyroid disorders may be involved.We aim to assess whether screening of frail elderly with reduced exercise tolerance leads to high detection rates of HF, COPD, or alternative diagnoses, and whether detection of these diseases would result in changes in patient management and increase in both functionality and quality of life. METHODS/DESIGN: A cluster randomized diagnostic trial. Primary care practices are randomized to the diagnostic-treatment strategy (screening) or care as usual. PATIENT POPULATION: Frail (defined as having three or more chronic or vitality threatening diseases and/or receiving five or more drugs chronically during the last year) community-dwelling persons aged 65 years and older selected from the electronic medical files of the participating general practitioners. Those with reduced exercise tolerance or moderate to severe dyspnoea (≥2 score on the Medical Research Counsel dyspnoea scale) are included in the study.The diagnostic screening in the intervention group includes history taking, physical examination, electrocardiography, spirometry, blood tests, and echocardiography. Subsequently, participants with new diagnoses will be managed according to clinical guidelines. Participants in the control arm receive care as usual. All participants fill out health status and other relevant questionnaires at baseline and after 6 months of follow-up. DISCUSSION: This study will generate information on the yield of screening for previously unrecognized HF, COPD and other chronic diseases in frail elderly with reduced exercise tolerance and/or exercise induced dyspnoea. The cluster randomized comparison will reveal whether this yield will result in subsequent improvements in functional health and/or health related quality of life. TRIAL REGISTRATION: ClinicalTrials.gov NCT01148719.

Brief eclectic psychotherapy v. eye movement desensitisation and reprocessing therapy for post-traumatic stress disorder: randomised controlled trial.

BACKGROUND: Trauma-focused cognitive-behavioural therapy (CBT) and eye movement desensitisation and reprocessing therapy (EMDR) are efficacious treatments for post-traumatic stress disorder (PTSD), but few studies have directly compared them using well-powered designs and few have investigated response patterns. AIMS: To compare the efficacy and response pattern of a trauma-focused CBT modality, brief eclectic psychotherapy for PTSD, with EMDR (trial registration: ISRCTN64872147). METHOD: Out-patients with PTSD were randomly assigned to brief eclectic psychotherapy (n = 70) or EMDR (n = 70) and assessed at all sessions on self-reported PTSD (Impact of Event Scale - Revised). Other outcomes were clinician-rated PTSD, anxiety and depression. RESULTS: Both treatments were equally effective in reducing PTSD symptom severity, but the response pattern indicated that EMDR led to a significantly sharper decline in PTSD symptoms than brief eclectic psychotherapy, with similar drop-out rates (EMDR: n = 20 (29%), brief eclectic psychotherapy: n = 25 (36%)). Other outcome measures confirmed this pattern of results. CONCLUSIONS: Although both treatments are effective, EMDR results in a faster recovery compared with the more gradual improvement with brief eclectic psychotherapy.

Prospective evaluation of non-pharmacological treatment in vasovagal syncope.

AIMS: Initial treatment of vasovagal syncope (VVS) consists of assuring an adequate fluid and salt intake, regular exercise and application of physical counterpressure manoeuvres. We examined the effects of this non-pharmacological treatment in patients with frequent recurrences. METHODS AND RESULTS: One hundred patients with > or =3 episodes of VVS in the 2 years prior to the start of the study openly received non-pharmacological treatment. We evaluated this treatment both with respect to syncopal recurrences, factors associated with recurrence, and quality of life (QoL). The median number of syncopal recurrences was lower in the first year of non-pharmacological treatment compared with the last year before treatment (median 0 vs. 3; P < 0.001), but 49% of patients experienced at least one recurrence. In multivariable analysis, a higher syncope burden prior to inclusion was significantly associated with syncopal recurrence. Disease-specific QoL improved over time, with larger improvements for patients with more reduction in syncope burden. CONCLUSION: In patients with frequent recurrences of VVS, non-pharmacological treatment has a beneficial effect on both syncopal recurrence and QoL, but nearly half of these patients still experience episodes of syncope.

A randomized controlled trial of enemas in combination with oral laxative therapy for children with chronic constipation.

BACKGROUND & AIMS: After 5 years of intensive oral laxative use, up to 30% of constipated children still have an unsuccessful outcome. Children refractory to oral laxatives might benefit from regular rectal evacuation by enemas. This randomized controlled trial compared the effects of additional treatment with rectal enemas (intervention) with conventional treatment alone (oral laxatives, control) in severely constipated children. METHODS: In a tertiary hospital in the Netherlands, 100 children, aged 8-18 years, with functional constipation for at least 2 years were randomly assigned to intervention or control groups. The control group received education, behavioral strategies, and oral laxatives. The intervention group was also given 3 rectal enemas/week, reduced by 1 enema/week every 3 months. Outcome measures were defecation and fecal incontinence frequency and overall success at 12, 26, 39, and 52 weeks. Overall success was defined as 3 or more defecations/week and less than 1 fecal incontinence episode/week, irrespective of laxative use. RESULTS: Defecation frequency normalized in both groups but was significantly higher in the intervention group compared with controls at 26 and 52 weeks (5.6 vs 3.9/week, P = .02, and 5.3 vs 3.9/week, P = .02, respectively). There were no significant differences between groups in reduction of fecal incontinence episodes (P = .49) and overall success rates (P = .67). After 1 year of treatment, the overall success rate was 47.1% in the intervention group versus 36.1% in the control group. CONCLUSIONS: There is no additional effect of enemas compared with oral laxatives alone as maintenance therapy for severely constipated children.

Longitudinal follow-up of children with functional nonretentive fecal incontinence.

BACKGROUND & AIMS: Functional nonretentive fecal incontinence (FNRFI), incontinence in the absence of signs of fecal retention, is a frustrating phenomenon in children. No data on long-term outcome are available. The aim was to investigate the long-term outcome of FNRFI patients after intensive medical treatment. METHODS: Between 1990 and 1999, 119 patients (96 boys) with FNRFI were enrolled in 2 prospective, randomized trials investigating the effect of biofeedback training and/or laxative treatment. Follow-up (FU) was performed at 6 months, 1 year, and thereafter annually until September 2004. A standardized questionnaire was used to evaluate symptoms. Success was defined as a fecal incontinence frequency <1 per 2 weeks. RESULTS: Median age (25th-75th percentiles) was 9.2 years (range, 7.9-11.6 years). A 90% FU was achieved at all stages of the study. After 2 years of intensive therapy, 33 of 112 (29.5%) patients were successfully treated. The cumulative success percentage after 7 years of FU was 80%. At the biologic ages of 12 and 18 years, 49.4% (40/81) and 15.5% (9/58), respectively, of the patients still had fecal incontinence. Duration of fecal incontinence, with 4 years of age as the starting age for fecal incontinence (when a child should be toilet trained), was not related to successful outcome or relapse. Relapse occurred in 37% of patients. CONCLUSIONS: Only 29% of the patients with FNRFI were successfully treated after 2 years of intensive treatment. Despite recovery in the majority of patients beyond puberty, at age 18 years, 15% continued to have fecal incontinence.

Diagnosis of Hirschsprung's disease: a prospective, comparative accuracy study of common tests.

OBJECTIVE: To compare the diagnostic accuracy of contrast enema (CE), anorectal manometry (ARM), and rectal suction biopsy (RSB) for the detection of Hirschsprung's disease (HD). STUDY DESIGN: Following a prospective protocol, infants suspected of HD underwent all 3 index tests. Children with positive results on 2 or more index tests or who continued to have severe bowel problems underwent a full thickness biopsy as reference standard. Clinical follow-up was the reference standard in all other children. RESULTS: Between 2000 and 2003, 111 consecutive patients (67 boys; median age, 5.3 months) in whom HD was suspected were enrolled. HD was found in 28 patients. RSB had the highest sensitivity (93%) and specificity (100%) rates, but values were not significantly different from CE (sensitivity, 76%; specificity, 97%) or from ARM (sensitivity, 83%; specificity, 93%). Inconclusive test results occurred in 8 infants with CE, in 15 infants with ARM because of agitation, and in 2 infants with RSB. CONCLUSION: RSB is the most accurate test for diagnosing HD, and it has the lowest rate of inconclusive test results.

Prognostic significance of elevated cyclooxygenase 2 expression in patients with adenocarcinoma of the esophagus.

BACKGROUND & AIMS: Use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with a reduced risk of cancer in the digestive tract. Cyclooxygenase (COX) is the best-known target of NSAIDs, and expression of the COX-2 isoform is elevated in esophageal carcinomas but its clinical significance remains unclear. We examined COX-2 expression in esophageal adenocarcinomas and its relation to clinicopathologic parameters. METHODS: Tumor sections from 145 consecutive patients undergoing intentionally curative surgery for an adenocarcinoma arising from a Barrett's esophagus were immunohistochemically stained using a COX-2-specific anti-human monoclonal antibody. The specimens were scored based on the intensity and extent of COX-2 immunopositivity. RESULTS: COX-2 immunoreactivity was negative to weak in 21% (COX-2 low) and moderate to strong in 79% (COX-2 high) of the carcinomas. Patients with high COX-2 expression were more likely to develop distant metastases (P = 0.02) and local recurrences (P = 0.05), and survival was significantly reduced (P = 0.002, log-rank test) among patients with high COX-2 expression when compared with the COX-2 low group. Five-year survival rates were 35% (95% confidence interval [CI], 23-47) and 72% (95% CI, 53-90) in COX-2 high and COX-2 low categories, respectively. Furthermore, expression of COX-2 was recognized as an independent prognostic factor by multivariate analysis (relative risk, 3.5; 95% CI, 1.6-7.9). CONCLUSIONS: Elevated expression of COX-2 protein is associated with significantly reduced survival of patients undergoing surgery for esophageal adenocarcinoma. These findings support the effort to initiate clinical studies to investigate the effect of COX-2 inhibitors as a novel (adjuvant) chemotherapeutic modality for the treatment of adenocarcinoma arising from Barrett's esophagus.
