Reduction of free water clearance with cephalic venous hypertension.

A laboratory model was developed in the dog to quantitate the effects of cerebral venous hypertension on inappropriate antidiuretic hormone (ADH) secretion. When cerebral venous pressure was abruptly increased during continuous water loading, there was a sharp rise in urine osmolality within 30 minutes. Urine osmolality continued to increase during, and ten minutes after, the period of hypertension. On lowering cerebral venous pressure, the osmolality returned to baseline within 60 minutes. The effects could be extended for at least three hours and presumably longer. A 50% response threshold for this ADH effect occurred at a cerebral venous pressure between 18 and 19 cm of water. The effect correlated with plasma ADH levels. The study paralled documented clinical observations. The results are discussed in light of the recognition and management of surgical states where increased cerebral venous pressure might produce a severe antidiuretic effect.

Sjogren's syndrome in SLE: Part I. The frequency of the clinical and subclinical features of Sjogren's syndrome in patients with SLE.

Clinical features of Sjogren's syndrome were found in 31 percent of 32 patients with SLE. Eight patients had features of KCS while four had xerostomia. Subclinical abnormalities were found in six other patients tested with sialography and labial salivary gland biopsy and there were abnormalities in 65 percent of SLE patients in whom labial salivary gland biopsy was performed. The prevalence of Raynaud's phenomenon and renal disease in SLE patients with and without Sjogren's syndrome were similar but four of the five patients with SLE and an erosive arthritis had symptomatic Sjogren's syndrome.

Sjogren's syndrome in SLE: Part 2. An examination of the clinical significance of Sjogren's syndrome by comparison of its frequency in typical and atypical forms of SLE, overlap syndromes and scleroderma.

The clinical features of Sjogren's syndrome were found in 24 percent of Glasgow patients with SLE without other atypical features. Sjogren's syndrome was found in one (13 percent) of a group of eight patients with features of both SLE and scleroderma, one of three patients with features of both polymyositis and scleroderma and in three of 12 (25 percent) patients with scleroderma. The highest frequency of Sjogren's syndrome was seen in six patients with features of SLE and an erosive polyarthritis, five of whom (83 percent) had Sjogren's syndrome. In patients satisfying diagnostic criteria for SLE no relationship between the presence of Sjogren's and the presence or absence of renal disease was found.

A physiologic approach to the problems of simutaneous bilateral neck dissection.

A number of physiologic derangements have been observed resulting from the management of head and neck cancer with resection and simultaneous bilateral neck dissection. A protocol evolved to minimize morbidity from these complications was used on seventeen patients. Eleven are alive and free of disease and there was no mortality.
