CONTEXT: There is some controversy whether T(4) treatment is indicated in obese humans with hyperthyrotropinemia. OBJECTIVE: The objective of this study was to examine whether hyperthyrotropinemia is a cause or a consequence of obesity. DESIGN: The study was designed as a cross-sectional comparison between obese and lean children and includes a 1-yr follow-up study. SETTING: The study was set in a primary care facility. PATIENTS: The patients were 246 obese and 71 lean children. INTERVENTION: The 1-yr intervention program was based on exercise, behavior therapy, and nutrition education. MAIN OUTCOME MEASURES: The main outcome measures were TSH, free T(3) (fT3), free T(4) (fT4), high-density lipoprotein, low-density lipoprotein, and total cholesterol at baseline and 1 yr later. RESULTS: TSH (P = 0.009) and fT3 (P = 0.003) concentrations were significantly higher in obese children than in normal weight children, whereas there was no difference in fT4 levels (P = 0.804). Lipids did not correlate significantly to thyroid hormones in cross-sectional and longitudinal analyses. fT3, fT4, and lipids did not differ significantly in the 43 (17%) children with TSH levels above the normal range from the children with TSH levels within the normal range. Substantial weight loss in 49 obese children led to a significant reduction of TSH (P = 0.035) and fT3 (P = 0.036). The 197 obese children without substantial weight loss demonstrated no significant changes of thyroid hormones. CONCLUSIONS: Because fT3 and TSH were moderately increased in obese children and weight loss led to a reduction, the elevation of these hormones seems to be rather a consequence of obesity than a cause of obesity. Because fT3 and TSH were both increased in obesity and thyroid hormones were not associated to lipids, we put forward the hypothesis that there is no necessity for thyroxine treatment.
BACKGROUND: Faecal incontinence is a common and potentially distressing disorder of childhood. OBJECTIVES: To assess the effects of behavioural and/or cognitive interventions for the management of faecal incontinence in children. SEARCH STRATEGY: We searched the Cochrane Incontinence Group Specialised Trials Register (searched 1 February 2006). SELECTION CRITERIA: Randomised and quasi-randomised trials of behavioural and/or cognitive interventions with or without other treatments for the management of faecal incontinence in children. DATA COLLECTION AND ANALYSIS: Reviewers selected studies from the literature, assessed study quality, and extracted data. Data were combined in a meta-analysis when appropriate. MAIN RESULTS: Eighteen randomised trials with a total of 1168 children met the inclusion criteria. Sample sizes were generally small. All studies but one investigated children with functional faecal incontinence. Interventions varied amongst trials and few outcomes were shared by trials addressing the same comparisons. Combined results of nine trials showed higher rather than lower rates of persisting symptoms of faecal incontinence up to 12 months when biofeedback was added to conventional treatment (OR 1.11 CI 95% 0.78 to 1.58). This result was consistent with that of two trials with longer follow-up (OR 1.31 CI 95% 0.80 to 2.15). In one trial the adjunct of anorectal manometry to conventional treatment did not result in higher success rates in chronically constipated children (OR 1.40 95% CI 0.72 to 2.73 at 24 months). In one small trial the adjunct of behaviour modification to laxative therapy was associated with a significant reduction in children's soiling episodes at both the three month (OR 0.14 CI 95% 0.04 to 0.51) and the 12 month assessment (OR 0.20 CI 95% 0.06 to 0.65). AUTHORS' CONCLUSIONS: There is no evidence that biofeedback training adds any benefit to conventional treatment in the management of functional faecal incontinence in children. There was not enough evidence on which to assess the effects of biofeedback for the management of organic faecal incontinence. There is some evidence that behavioural interventions plus laxative therapy, rather than laxative therapy alone, improves continence in children with functional faecal incontinence associated with constipation.
BACKGROUND: Borderline personality disorder (BPD) is a relatively common personality disorder with a major impact on health services as those affected often present in crisis, often self-harming. OBJECTIVES: To evaluate the effects of psychological interventions for people with borderline personality disorder. SEARCH STRATEGY: We conducted a systematic search of 26 specialist and general bibliographic databases (December 2002) and searched relevant reference lists for further trials. SELECTION CRITERIA: All relevant clinical randomised controlled trials involving psychological treatments for people with BPD. The definition of psychological treatments included behavioural, cognitive-behavioural, psychodynamic and psychoanalytic. DATA COLLECTION AND ANALYSIS: We independently selected, quality assessed and data extracted studies. For binary outcomes we calculated a standard estimation of the risk ratio (RR), its 95% confidence interval (CI), and where possible the number need to help/harm (NNT/H). For continuous outcomes, endpoint data were preferred to change data. Non-skewed data from valid scales were summated using a weighted mean difference (WMD). MAIN RESULTS: We identified seven studies involving 262 people, and five separate comparisons. Comparing dialectical behaviour therapy (DBT) with treatment as usual studies found no difference for the outcome of still meeting SCID-II criteria for the diagnosis of BPD by six months (n=28, 1 RCT, RR 0.69 CI 0.35 to 1.38) or admission to hospital in previous three months (n=28, 1 RCT, RR 0.77 CI 0.28 to 2.14). Self harm or parasuicide may decrease at 6 to 12 months (n=63, 1 RCT, RR 0.81 CI 0.66 to 0.98, NNT 12 CI 7 to 108). One study detected statistical difference in favour of people receiving DBT compared with those allocated to treatment as usual for average scores of suicidal ideation at 6 months (n=20, MD -15.30 CI -25.46 to -5.14). There was no difference for the outcome of leaving the study early (n=155, 3 RCTs, RR 0.74 CI 0.52 to 1.04). For the outcome of interviewer-assessed alcohol free days, skewed data are reported and tend to favour DBT. When a substance abuse focused DBT was compared with comprehensive validation therapy plus 12-step substance misuse programme no clear differences were found for service outcomes (n=23, 1 RCT, RR imprisoned 1.09 CI 0.64 to 1.87) or leaving the study early (n=23, 1 RCT, RR 7.58 CI 0.44 to 132.08). When dialectical behaviour therapy-oriented treatment is compared with client centred therapy no differences were found for service outcomes (n=24, 1 RCT, RR admitted 0.33 CI 0.08 to 1.33). However, fewer people in the DBT group displayed indicators of parasuicidal behaviour (n=24, RR 0.13 CI 0.02 to 0.85, NNT 2 CI 2 to 11). There were no differences for outcomes of anxiety and depression (n=24, 1 RCT, RR anxiety BAI >/=10 0.60 CI 0.32 to 1.12; RR depression HDRS >/=10 0.43 CI 0.14 to 1.28) but people who received DBT had less general psychiatric severity than those in the control (MD BPRS at 6 months -7.41 CI -13.72 to -1.10). Finally this one relevant study reports skewed data for suicidal ideation with considerably lower scores for people allocated to DBT. When psychoanalytically oriented partial hospitalization was compared with general psychiatric care the former tended to come off best. People who received treatment in a psychoanalytic orientated day hospital were less likely to be admitted into inpatient care when measured at different time points (e.g. n=44, RR admitted to inpatient 24 hour care >18 to 24 months 0.05 CI 0.00 to 0.77, NNT 3 CI 3 to 10) Fewer people in psychoanalytically oriented partial hospitalization needed day hospital intervention in the 18 months after discharge (n=44, 1 RCT, RR 0.04 CI 0.00 to 0.59, NNT 2 CI 2 to 8). More people in the control group took psychotropic medication by the 30 to 36 month follow-up, than those receiving psychoanalytic treatment (n=44, 1 RCT, RR 0.44 CI 0.25 to 0.80, NNT 3 CI 2 to 7). Anxiety and depression scores were generally lower in the psychoanalytically oriented partial hospitalization group (n=44, 1 RCT, RR >/=14 on BDI 0.52 CI 0.34 to 0.80, NNT 3 CI 3 to 6), as are global severity scores. People receiving psychoanalytic care in a day hospital had better social improvement in social adjustment using the SAS-SR at 6 to 12 months compared with people in general psychiatric care (MD -0.70 CI -1.08 to -0.32). Rates of attrition were the same (n=44, 1 RCT, RR leaving the study early 1.00 CI 0.23 to 4.42). AUTHORS' CONCLUSIONS: This review suggests that some of the problems frequently encountered by people with borderline personality disorder may be amenable to talking/behavioural treatments but all therapies remain experimental and the studies are too few and small to inspire full confidence in their results. These findings require replication in larger 'real-world' studies.
