Tumours of the nasal cavity.

Tumours of the nasal cavity are rare in domestic animals, most cases occurring in the dog. Epithelial tumours are the most common type in carnivores (dogs and cats). In general, the same types of tumour occur in domestic animals as occur in man. There was no significant predisposition for breed in dogs, but in both dogs and cats far more males than females were affected. Metastases occurred only rarely.

Circadian rhythm of cardiac responses to vagal stimulation tests.

To evaluate the existence of a circadian rhythm in cardiac responses to vagal stimulation tests, 10 children without neurologic or cardiopulmonary disease, were studied using a standardized procedure. A trigeminal airstream stimulation test (TAS) and an ocular compression test (OCT) were subsequently performed at 4 nonequidistant hours. These 2 vagal stimulation tests were performed according to well-established, previously published techniques. Prolongation of the RR-interval during TAS and OCT was calculated and compared to the mean control RR-interval preceding the stimulation period. Prolongation of the RR-interval during the stimulation period was obtained in all instances during TAS and OCT. Chronobiologic analysis was determined by the cosinor method and bootstrap analysis. A significant circadian rhythm was found in cardiac responses to vagal stimulation for both TAS and OCT. The maximal response hour for TAS was between 9:06 p.m. and 5:18 a.m. and for OCT between 10:18 p.m. and 4:24 a.m. The mean value and 95% intervals for the cardiac responses to both vagal stimulation tests revealed, when using the bootstrap analysis, an important overlap in the hour of appearance of the maximal responses to these procedures; the bootstrap analysis of the peak of the acrophase was at 2:50 a.m. for TAS and 1:15 a.m. for OCT. Our results indicate that there is a circadian rhythm in cardiac responses to vagal stimulation tests and demonstrate a preponderance of these responses during the early morning hours.

Plasma amino acid concentrations in term-born infants fed a whey predominant or a whey hydrolysate formula.

BACKGROUND: Hydrolysates are used in the treatment and prevention of cows milk protein allergy. Hydrolysis might alter the plasma level of amino acids. METHODS: Forty-five infants were included in a double-blind prospective study and were randomized in two groups: one receiving a whey predominant formula (n = 20) and the second group receiving a whey hydrolysate formula (n = 25). Weight and length gain was evaluated up to the age of 13 weeks, when blood was sampled for determination of fasting plasma amino acids. RESULTS: Four infants of the hydrolysate group dropped out because refusal to ingest the formula. Weight and length gain at 13 weeks of age were extremely comparable. Significant differences in plasma concentrations were observed for a number of nonessential and essential amino acids (p = .035 to .0001). Threonine and lysine were both higher in the hydrolysate group, and aspartic acid, cystine, methionine, tyrosine, phenylalanine, histidine, and arginine were lower in the hydrolysate group. CONCLUSIONS: These differences in plasma amino acid levels have to be regarded with care because all concentrations were within normal ranges, with the exception of threonine. Weight and length gain of the hydrolysate and the whey predominant formula were identical.

Radiotherapy in three suspect cases of feline thymoma.

Radiation therapy for three cases of suspect feline thymoma is described. The thymoma was controlled for 4 years in case no. 1. Case no. 2 responded well to radiation therapy but was euthanized after 2 months because of a nasal adenocarcinoma. Case no. 3 continues to do well more than 8 months after radiotherapy. Difficulties in diagnosing feline thymomas are discussed, and biological behavior as well as different treatment modalities of feline and human thymomas are compared.
