The adrenocorticotrophic hormone (4-9) analog ORG 2766 benefits autistic children: report on a second controlled clinical trial.

In a second controlled crossover trial, 20 autistic children received 40 mg/day of the neuropeptide ORG 2766, a synthetic analog of ACTH (4-9), for 8 weeks. Parents' checklist ratings (ABC) as well as clinicians' ratings (CGI) pointed to significant improvements after the course of treatment; improvements were clearest on the ABC social withdrawal subscale. The analysis of individual target symptoms and the parents' treatment preferences substantiated the beneficial effects of ORG 2766. In an ethologically analyzed playroom session, ORG 2766 treatment was associated with an improvement in the children's play behavior and a significant increase in the social interaction between child and experimenter. Gaze coordination between child and experimenter also was improved.     

Reperfusion injury of pancreas allografts: relation to islet cell function

It is unknown to what extent preservation and/or reperfusion may damage islet cells in pancreas allografts. In this study, the release of insulin after reperfusion was used as a marker of injury to the islet cell and compared with the best insulin secretory response (ISR) after glucagon stimulation over a period of 100 days after pancreas transplantation.     

Similarities in Skeletal Muscle Strength and Exercise Capacity Between Renal Transplant and Hemodialysis Patients

Exercise intolerance is common in hemodialysis (HD) and renal transplant (RTx) patients. Aim of the study was to assess to what extent exercise capacity and skeletal muscle strength of RTx patients differ from HD patients and healthy controls and to elucidate potential determinants of exercise capacity in RTx patients. Exercise capacity, muscle strength, lean body mass (LBM) and physical activity level (PAL) were measured by cycle-ergometry, isokinetic dynamometry, DEXA and Baecke Questionnaire, respectively, in 35 RTx, 16 HD and 21 controls. VO2peak and muscle strength of the RTx patients were significantly lower compared to controls (p<0.01), but not different compared to HD patients. In RTx patients, strength (p<0.001), PAL (p=0.001) and age (p=0.045) were significant predictors of VO2peak. Muscle strength was related to LBM (p=0.001) and age (p=0.001), whereas gender (p<0.001) and renal function (p=0.01) turned out to be significant predictors of LBM. No effects of corticosteroids were observed. Exercise capacity and muscle strength seem equally reduced in RTx and HD patients compared to controls. In RTx patients, muscle strength and PAL are highly related to exercise capacity. Renal function appears to be a significant predictor of LBM, and through the LBM, of muscle strength and exercise capacity.     

Differences between conduct disordered and normal control children in their tendencies to escalate or neutralize conflicts when interacting with normal peers

The behavior of conduct disordered (CD) children was compared with normal control (NC) children in interaction with normal peers. Dyads consisting of a) a CD child and a normal peer and b) an NC child and the same normal peer as in a) were observed. CD boys were less able than NC boys to neutralize incipient conflicts. Hitherto most behavioral studies of CD boys have concentrated on their tendency to escalate conflicts but have paid very little attention to their difficulty in neutralizing conflicts.     

Recurrence of nephrocalcinosis after renal transplantation in an adult patient with primary hyperoxaluria type I

The medical history of a 42-year-old patient with primary hyperoxaluria type I is presented. Primary hyperoxaluria was suspected after renal transplantation, when oxalate deposits were found in a biopsy of the kidney graft. Diagnosis of type I hyperoxaluria was confirmed by the finding that significantly increased amounts of glycolic acid and oxalic acid were excreted. Treatment of the patient with 500 mg pyridoxine daily resulted in a decrease of the excretion of oxalate to normal values.     

Detection of HLA class I and II antibodies by ELISA and complement-dependent cytotoxicity before and after transplantation

BACKGROUND: Anti-class I IgG can be detected by complement-dependent cytotoxicity (CDC) and by ELISA. We compared ELISA and CDC for both class I and class II antibodies on method agreement and relation to rejection-free and graft survival. METHODS: Peak, current, and posttransplant sera (n=429) of 143 renal allograft patients were tested by National Institutes of Health technique (NIHT), two-color fluorescence (TCF), and ELISA. Method agreement was assessed by intraclass correlation coefficient (ICC). Rejection and graft survival were analyzed by uni- and multivariate techniques. The screening results for each serum were compared, as was the change in result of current to posttransplant serum. RESULTS: The ICC of ELISA and NIHT was insufficient; it was lower for TCF than NIHT. Graft survival was not related to the result of any assay. Rejection-free survival was related to ELISA and NIHT in current and posttransplant serum. With the NIHT, the change in percent panel-reactive antibody (%PRA) correlated better with rejection than it did with ELISA. The combined antibody status of current and posttransplant serum was a risk factor for rejection in all assays, and for TCF also in multivariate analysis. The rejection rate was higher if the posttransplant serum was ELISA-negative/CDC-positive, rather than ELISA-positive/CDC-negative. For ELISA, class I specificities (and not %PRA) in peak and current sera were related to rejection, even if the antibodies were not donor-directed. In the case of the National Institutes of Health technique (NIHT), %PRA and not specificity was related to rejection. Class II antibodies were never related to rejection. CONCLUSIONS: ELISA and NEIT are complementary screening techniques in this patient population. They are of equal predictive value for rejection. The optimal strategy in combining these techniques must be determined.     

Non-surgical treatment for adult spinal deformity: results of an intensive combined physical and psychological programme for patients with adult spinal deformity and chronic low back pain—a treatment-based cohort study

Objectives

No evidence-based treatment exists for adult spinal deformity (ASD) patients with chronic low back pain (CLBP). Aim of this study: evaluate a combined physical and psychological programme (CPPP) for ASD patients with CLBP and to compare this with a non-ASD-cohort with CLBP.

Methods

Data were extracted from the database of CLBP-patients for whom surgery is not an option and completed CPPP. Two cohorts were selected: an ASD-cohort (n = 80) based on a Cobb angle of > 10° and a consecutive age- and gender-matched non-ASD-cohort (n = 240). Primary outcome: functional status (Oswestry Disability Index; ODI). Secondary outcomes: pain intensity, self-efficacy and quality of life. Assessments: pre and post treatment, one-month and one-year follow-up (FU). Clinical relevance: minimal important clinical change (MCIC; ODI 10 points), patient acceptable symptom state (PASS; ODI ≤ 22).

Results

Demographics ASD-cohort: 79% female, mean age 50.9 (± 14.1) years, mean CLBP duration 15.5 (± 12.5) years, mean Cobb angle 21.4 (± 9.4)°. Non-ASD-cohort: not significantly different. Both cohorts improved in functional status (F[1,318] = 142.982, p < .001; r = 0.31). The ASD-cohort improved from mean ODI 39.5(± 12.0) at baseline to mean ODI 31.8(± 16.5) at one-year FU. Clinical relevance: 51% of the ASD patients reached MCIC and 33% reached a PASS. An interaction effect is shown between time and both cohorts (F[1,318] = 8.2, p = .004; r = 0.03); however, not clinically relevant. All secondary outcomes: improvement at one-year FU.

Conclusion

This is the first study showing beneficial outcomes of a non-surgical treatment in selected ASD patients with longstanding CLBP. Improvement is shown in functional status, and appeared equivalent to the non-ASD cohort.

Psychiatric outcomes amongst adult survivors of childhood burns

Background

Research on the adult psychiatric outcomes of childhood burns is limited.

Aims

To examine the rates of DSM-IV psychiatric disorder amongst adult survivors of paediatric burns, and to explore factors likely to contribute to variation in outcomes. In line with Meyer and colleagues [1], it was expected that high levels of psychopathology would be found.

Method

Participants were 272 adults hospitalised for burns during childhood between the years 1980 and 1990. Structured interviews and self-report questionnaires were used to assess psychiatric symptoms.

Results

Lifetime prevalence of any DSM-IV disorder was 42%, 30% for depressive disorders, and 28% for anxiety disorders. Eleven percent had made a suicide attempt. Female gender, single relationship status, higher level of disfigurement, longer hospital stays and higher number of burn-related surgeries were associated with adverse psychiatric outcomes.

Conclusions

High rates of suicidality and depression were concerning in adults with a history of childhood burns. Factors found to predict psychiatric outcomes could be used to direct interventions and further research is needed to establish how this could best be done.
