Speech and lingual behavior before and after mandibular osteotomy.

A procedure was applied to compare the oral behavior of five patients before and after mandibular osteotomy for correction of Class III malocclusions. It was found that observable changes in oral behavior do occur after mandibular osteotomy. Fewer errors were found in sibilant articulation, while more maladaptive lingual behaviors were found in lingual diadochokinetic tasks. Changes were also found in swallowing behaviors. Performance tasks of speech, diadochokinetics, and swallowing were recorded on audio-videotape.

Towards a broader view of recovery.

It is estimated that tobacco use accounts for 25% of the total economic cost of illness in America. Chemically dependent patients have a smoking rate that ranges from 80% to 95% in different studies, almost triple the national average. Despite these staggering statistics, only a handful of chemical dependency treatment programs treat nicotine as an addictive drug and actively encourage their patients to quit. Denial by treatment staff and fears in the Recovery community that Recovery would be jeopardized by quitting are two factors contributing to the reluctance to develop smoke-free programs and treat nicotine dependence. The fear that patients would refuse admission to a facility that prohibits smoking and resistance from staff who smoke appear to be the major barriers to adopting a smoke-free policy. The time has come to face the burdensome costs of tobacco use and to address nicotine dependence in chemical dependents. It is time to develop a broader view of Recovery.

Plasma lipid levels in insulin-dependent diabetes mellitus.

Because several recent reports have indicated a high incidence of hyperlipidemia in insulin-dependent juvenile diabetes, the plasma lipid levels were measured in a population of insulin-dependent diabetic patients to determine if hyperlipidemia is necessarily associated with diabetes. Only one patient had an elevated cholesterol concentration (greater than 220 mg. per deciliter) and two patients had an elevated triglyceride concentration (greater than 140 mg. per deciliter), giving an incidence of 6.4 per cent. A normal control group had an incidence of hyperlipidemia of 5.7 per cent. The mean cholesterol level (164 "/- 38 mg. per deciliter) of the diabetic population was significantly less than that of the normal control group (183 +/- 38 mg. per deciliter). The diabetic patients were divided into groups on the basis of 24-hour urinary glucose excretion and records of glycosuria. The serum triglyceride of the patients in group 4 (highest urinary glucose content and spills) was significantly elevated above three other groups with less glucosuria. Dietary history revealed that group 4 patients consumed a significantly higher percentage of fat. Cholesterol levels did not correlate with parameters of regulation of the diabetes.

Lack of relationship between parity and level of carcinoembryonic antigen in women with breast cancer.

Women with high parity appear to be protected against the development of breast cancer. It has been suggested that those tumours which secrete carcinoembryonic antigen (CEA) are destroyed in women who develop cell-mediated immunity to embryonic antigen at the time of pregnancy or childbirth at an early age. A study of 335 patients with breast cancer was designed to test the hypothesis that circulating levels of CEA would be lower in women with high parity and an early age at first pregnancy or live birth. CEA levels were higher if measured in the presence of tumour metastasis. There was no association between CEA levels and parity, age at first live birth, age at diagnosis or cigarette smoking. Thus we have no evidence that breast cancers which express embryonic antigens, such as CEA, are preferentially destroyed by an immune response which has arisen from embryonic inoculation during or around an early childbirth.
