A case of arm swelling and muscle Wii-kness.

The Nintendo Wii is now the world's most popular home games console owing to its simple interface and replication of sports activities. Although safety advice is provided by the manufacturer, a number of injuries have previously been described. We describe a case of arm swelling with associated rise in serum creatine kinase to over 8000 U/L in a man, following unaccustomed and sustained strenuous muscle exertion through the use of the Nintendo Wii. His condition spontaneously resolved with rest and conservative measures. His presentation represents significant muscle injury through the use of this games console and the replication of sporting activities; physicians should be aware of the variety of musculoskeletal presentations such use of these devices can produce.

Neuropsychological deficits associated with schizophrenic syndromes.

A battery of computerised tests and the classical Stroop test were administered to a group of 56 patients with DSM-III-R schizophrenia and 17 controls to explore the nature of the mental processes associated with the psychomotor poverty and disorganisation syndromes. In patients with persistent illness, psychomotor poverty was associated with slower responses in a two-choice guessing task in which the appropriate response was not dictated by the circumstances. This association was not observed in patients with remitting illness, providing neuropsychological support to the distinction between 'negative' and 'deficit' symptoms in schizophrenia. Disorganisation syndrome was associated with impaired performance in the classical Stroop test, as shown in previous studies, but not with impairment in a task which required suppression of processing of irrelevant aspects of a stimulus, nor with impairment in a task which required the suppressing of a primed but irrelevant non-verbal response. This suggests that the disorganisation syndrome might be associated with a specific difficulty in suppressing irrelevant verbal responses.
