The case of an infant admitted for evaluation of severe emaciation with intermittent ocular anomalies including strabismus and nystagmus is reported. This case demonstrates the value of magnetic resonance imaging and transfontanellar ultrasonography for the diagnosis of diencephalic syndrome of infancy. The prognosis of this condition is usually grim, in particular because of the severe emaciation which is disproportionate with the tumour spread. Pathophysiologic hypotheses put forward to explain this cachexia are reviewed. Although cytokines such as TNF alpha are currently incriminated in the pathophysiology of cachexia induced by a number of conditions, they have not yet been studied in diencephalic syndrome of infancy. TNF alpha is a potent lipolytic agent. Excessive production of TNF alpha may be involved in the genesis of the emaciation characteristic of diencephalic syndrome. Inappropriate production of TNF alpha may respond to the administration of specific anti-TNF monoclonal antibodies. This approach may be considered as a means for treating emaciation in patients with diencephalic syndrome of infancy.

Unusual clinical and pathological observations in the field in goats and sheep suffering from Strongyloides papillosus infection prompted experimental work on this parasite. Goats were infected percutaneously with either single or multiple, low or high levels of S. papillosus. Young goats up to 12 months of age were found to be the most susceptible. Some animals, however, showed substantial resistance to infective doses. Clinical signs included transient diarrhoea, misshapen, elongated faecal pellets terminally, dehydration, anorexia, cachexia, gnashing of teeth, foaming at the mouth, anaemia and nervous signs such as ataxia, a wide-based stance, stupor and nystagmus. A 'pushing syndrome' was seen in 22% of the animals. The pathological changes are described and included enteritis, status spongiosus in the brain, hepatosis leading to rupture of the liver, nephrosis, pulmonary oedema, interstitial pneumonia and pneumonia. About 6% of the goats died acutely from fatal hepatic rupture. The development of an acquired immunity was determined. The immunity elicited an allergic skin reaction at the application site of larvae or injection sites of larval metabolites. This immunity, however, could be breached by large doses of larvae. The most profound clinicopathological changes induced by the parasites were an anaemia (most pronounced in the young goats) and hypophosphataemia. Trace element analyses provided evidence of Cu, Mn and possibly Se deficiencies in some goats.

Atypical Teratoid Rhabdoid Tumor (ATRT) is a rare malignant intracranial neoplasm more commonly diagnosed in young children. The authors report the case of an 11-year-old boy with a long standing history of slowly progressive weight loss, fatigue, and weakness over 1.5 years whose magnetic resonance imaging revealed a large heterogeneous enhancing dorsally exophytic lower brainstem mass. Examination revealed extreme cachexia, gaze-evoked nystagmus, dysphagia, dysarthria, bilateral dysmetria, and global weakness without ambulation. The protracted history and neuroimaging features were most suggestive of a low grade glioma. However, pathology revealed a hypercellular tumor with large hyperchromatic nucleoli and loss of INI-1 staining on immunohistochemistry consistent with a diagnosis of an ATRT. The child died shortly after surgery due to complications from his brainstem infiltrative disease. This case illustrates the diverse presentation of ATRT in childhood that can clinically and radiographically mimic that of low grade glioma.
