A child is described who presented in the neonatal period with feeding difficulties, severe neurological abnormalities, lens dislocation of the eyes and dysmorphic symptoms of the head. Routine laboratory investigations revealed a decreased serum urate and a positive sulphite reaction of the urine. Subsequent chromatographic examinations showed xanthinuria and increased excretion of S-sulphocysteine and taurine to be present. In addition, high thiosulphate and low sulphate excretions in the urine were observed. Xanthine oxidase deficiency was demonstrated in a jejunal biopsy specimen, whereas the excretion of sulphur containing substances was considered to be characteristic of sulphite oxidase deficiency. This new combination of defects may be the result of malfunctioning of both enzymes, possibly caused by alterations in the essential molybdenum containing active centre of the enzymes, which they share in common.

A patient suffering froma mitochondrial myopathy leading to severe insufficiency of the voluntary muscles is described. Severe cerebral damage was present. Major biochemical symptoms were extreme lactic acidemia, hypophosphatemia and hyperphosphaturia, and generalized aminoaciduria, renal glucosuria, and polyuria. Muscular insufficiency resulted in lethal asphyxiz. All therapeutic trials were insufficient. The patient and two other children of the same family with a similar clinical picture all died before the 4th month of life. The condition is probably inherited in an autosomal recessive way. A defective respiratory chain in the mitochondria of the striated muscles is proposed as the underlying mechanism. Cytochromes aa3 were absent, b was nearly absent, but cc1 was present. In heart muscle cytochromes aa3 and b were at the level of the controls.

Intolerance of uncertainty (IU) is thought to play a key role in the development and maintenance of worry and generalised anxiety disorder (GAD). The present study investigated the psychometric properties of the Dutch translation of the Intolerance of Uncertainty Scale (IUS), the most frequently employed scale for measuring IU. The factor analysis of the IUS pointed in the direction of a one-factor solution. Furthermore, the Dutch IUS portrayed excellent internal consistency and testretest reliability. Tests of construct validity showed that the Dutch IUS correlated significantly more strongly with worry than with depression. The regression analysis demonstrated that IU contributed significantly to worry, after controlling for demographic variables and levels of anxiety and depression. In addition, it was demonstrated that the IUS successfully discriminated between patients with GAD and other anxiety disorders, and non-clinical participants. Overall, it seems safe to conclude that the Dutch IUS is a reliable and valid scale for assessing IU. (Netherlands Journal of Psychology, 62,(91)(92)(93)(94)(95)(96)(97)

Background Although early results of bariatric surgery are beneficial for most patients, some patients regain weight later. Cognitive behavioral therapy (CBT) has been suggested as a way to improve patients’ psychological health and maintaining weight loss in the longer term. The added value of preoperative CBT to bariatric surgery was examined. Pre- and posttreatment and 1-year follow-up data are presented. Methods In a multi-center randomized controlled trial, CBT was compared to a treatment-as-usual (TAU) control group. Measurements were conducted pre- and posttreatment/pre-surgery (T0 and T1) and at 1-year post-surgery (T2). Patients in the intervention group received 10 individual, weekly sessions of preoperative CBT focused on modifying thoughts and behaviors regarding eating behavior, physical exercise, and postoperative life style. Outcome measures included weight change, eating behavior, eating disorders, depression, quality of life, and overall psychological health. Results Though no significant differences between conditions were found per time point, in the CBT, condition scores on external eating, emotional eating, depressive symptoms, and psychological distress decreased significantly more over time between pre- (T0) and posttreatment (T1) pre-surgery compared to TAU. No significant time x condition differences were found at 1-year post-surgery (T2). Conclusions Compared to TAU, preoperative CBT showed beneficial effects on eating behavior and psychological symptoms only from pretreatment to posttreatment/pre-surgery, but not from pre-surgery to 1-year post-surgery. Preoperative CBT does not seem to contribute to better long-term outcomes post-surgery. Recent studies suggest that the optimal time to initiate psychological treatment may be early in the postoperative period, before significant weight regain has occurred.

CBT seems to be effective in reducing risk factors for weight regain after bariatric surgery, such as disordered eating behavior and depression. Controlled studies with long-term follow-up and larger sample sizes are needed to investigate the long-term effect of CBT interventions on weight loss results and psychological well-being.
