Wernicke's encephalopathy after vertical banded gastroplasty for morbid obesity.

Thiamine deficiency is known to lead to certain neurological sequelae including Wernicke- Korsakoff encephalopathy. Signs attributable to this condition include ataxia, ophthalmoplegia, nystagmus, and mental confusion. Recognised predisposing conditions include alcoholism gastric carcinoma, pyloric obstruction, hyperemesis gravidarum, and prolonged intravenous feeding. We have recently encountered two cases of Wernicke's encephalopathy after vertical banded gastroplasty for morbid obesity . Other neurological sequelae are recognised after vertical banded gastroplasty, including Guillain-Barre syndrome, psychosis, and pseudoathetosis, but the causes are multifactorial.

Ventilatory failure in myasthenia gravis.

This retrospective study over the decade 1969-1978 examines the precipitating factors and outcome in thirty-one patients with myasthenia gravis who developed ventilatory failure. An unusual example of chronic alveolar hypoventilation is discussed in detail. The most favourable outcome occurred in younger patients with a hyperplastic thymus, in contrast to a poorer outlook for older patients with an atrophic gland. Eleven patients died during the period of follow up: three deaths were unrelated to myasthenia but the remaining eight were attributed directly or indirectly to it. The mortality of 36% represents a marked improvement on a 70% mortality in a similar group of patients, reported from this hospital for the years 1960-1968.

Association between polyneuritis and multiple sclerosis.

We report two cases in which multiple sclerosis and inflammatory polyneuritis occurred separately, and suggest that this association supports the idea that the two conditions may have an aetiological link.

The thoracic outlet syndrome.

Thirty-one patients with thoracic outlet syndrome have been studied in detail in the neurological and vascular clinics at this hospital. The patients were classified on the basis of their presenting symptoms into four groups--predominantly vascular, neurological, combined vascular and neurological, and pain and paraesthesiae alone. The majority of patients had radiological abnormalities and all had structural lesions in the superior thoracic aperture seen at operation. All operations were carried out through a standard supraclavicular approach, enabling the compressive structures to be visualized. This would not have been the case had the commoner trans-axillary approach for first rib resection been followed and in fact none of the operations included removal of the first rib. The results of operation were evident in our patients with a marked relief in their vascular symptoms, their pain and paraesthesiae and a slight but definite improvement in muscle bulk and power.

Unilateral cataplexy associated with systemic lupus erythematosus.

A patient with systemic lupus erythematosus (SLE) developed attacks of unilateral cataplexy precipitated by laughter. Unilateral cataplexy has not been described previously in detail and its association with SLE is unique. The clinical details, investigations, and diagnostic criteria are discussed and a causal relationship between cataplexy and SLE is suggested.

Abetalipoproteinaemia. A case report with pathological studies.

The clinical and pathological features of a case of abetalipoproteinaemia in a 38-year-old patient are described in detail. A feature not previously recorded was a marked reduction in the velocity of ocular horizontal saccadic movements. Pathological studies revealed an active chronic demyelinating process. The patient showed no response to large doses of vitamin E. The rationale for this therapy, and the possible reasons for its failure are discussed.
