Fibromatosis of bone in children

Radiographs, computed tomograms, and radionuclide bone scans were obtained preoperatively in three children with fibromatosis involving the bones and soft tissues of the extremities. Two of the children had identical scar-like bone lesions of the proximal tibia, which, to the authors' knowledge, have not been reported before in this disease. The lesions recurred in two children.     

Emphysema in the renal allograft

Two diabetic patients in whom emphysematous pyelonephritis developed after renal transplantation are described. Clinical recognition of this unusual and serious infection is masked by the effects of immunosuppression. Abdominal radiographic, ultrasound, and computed tomography findings are discussed. The clinical presentation includes urinary tract infection, sepsis, and acute tubular malfunction of the allograft in insulin-dependent diabetics.     

Non-declarative memory in the rehabilitation of amnesia

The ability of amnesic patients to learn and retain non-declarative information has been consistently demonstrated in the literature. This knowledge provided by basic cognitive neuroscience studies has been widely neglected in neuropsychological rehabilitation of memory impaired patients. This study reports the case of a 43 year old man with severe amnesia following an anterior communicating artery (ACoA) aneurysm rupture. The patient integrated a comprehensive (holistic) day treatment programme for rehabilitation of brain injury. The programme explored the advantages of using preserved non-declarative memory capacities, in the context of commonly used rehabilitation approaches (i.e. compensation for lost function and domain-specific learning). The patient's ability to learn and retain new cognitive and perceptual-motor skills was found to be critical for the patient's improved independence and successful return to work.     

Sex steroids and spermatogenesis in the African catfish (Clarias gariepinus)

Little is known about the physiological regulations of spermatogenesis of the African catfish (Clarias gariepinus), a species used as an experimental model for two decades. After a brief introduction to the cystic type of spermatogenesis in fish, the role of androgens and estrogens will be discussed, leading to a conclusion that androgens are required for spermatogenesis while their mode of action is poorly understood. In the cystic mode of spermatogenesis in fish, the Sertoli cells are formed cystic, in the somniferous lobules enclosing a single germ cell clone, providing suitable experimental models to address questions of relevance for vertebrate spermatogenesis in general.     

A population-based study of anxiety as a precursor for depression in childhood and adolescence

Background  

Anxiety and depression co-occur in children and adolescents with anxiety commonly preceding depression. Although there is some evidence to suggest that the association between early anxiety and later depression is explained by a shared genetic aetiology, the contribution of environmental factors is less well examined and it is unknown whether anxiety itself is a phenotypic risk factor for later depression. These explanations of the association between early anxiety and later depression were evaluated.

Papaveretum infusions in infants under 6 months of age

The effectiveness of a continuous low dose papaveretum infusion for the relief of postoperative pain was assessed in 29 infants aged 1-6 months nursed on the infant surgical ward following major abdominal surgery. Trained nursing staff were able to adjust the dosage within prescribed guidelines and satisfactory analgesia was obtained with a regimen which delivered up to 0.0375 mg/kg/hour, approximately half the dose recommended in children older than 12 months. There was one case of clinically significant respiratory depression.
