The insertion of prostheses at mastectomy for carcinoma of the breast--a preliminary report.

There has been a move away from radical surgery for carcinoma of the breast to more conservative measures. However, even simple mastectomy causes considerable mutilation and is psychologically very upsetting for most patients. This has led to attempts at reconstruction of the breast and more recently to prostheses being inserted at the time of mastectomy (1). The early results of this procedure in 30 patients--the total experience of a general surgeon--are reported in this paper.

Exploration of the common bile duct--the relevance of the clinical picture and the importance of peroperative cholangiography.

A series of 500 cholecystectomies performed over a 7-year period was reviewed retrospectively. The reliability of preoperative clinical features such as jaundice and pancreatitis was assessed in determining the presence of choledocholithiasis, and was found to be of limited value. Investigations such as intravenous cholangiography and liver function tests were found also to be inaccurate in the detection of common duct stones as was the appearance of the duct at operation. The usefulness of the peroperative cholangiogram in the detection of common duct stones that would otherwise have been overlooked is emphasized. Common duct stones would have remained undetected in 25 per cent of patients with choledocholithiasis. Despite the use of routine peroperative cholangiography common duct stones were overlooked in 11.25 per cent of patients who underwent exploration.

Incidence of sperm antibodies before and after vasectomy.

Sperm-agglutinating antibodies were present in three (2-6%) of 117 fertile men and in 19 (33-9%) of 56 men who had been vasectomized. Twenty-four of the 56 vasectomized men had been studied before vasectomy; sperm-agglutinating antibodies were present in one (4-3%) compared with eight (33-3%) after vasectomy. No sperm-immobilizing antibodies were detected before vasectomy but were present in 10 (17-9%) of the 56 men after vasectomy.

Initial results of the use of a drug-interaction system.

Dentists' knowledge about drug interactions, particularly in medically compromised older patients, may not be adequate. An on-line drug interaction system was tested for 4 months in a dental clinic to ascertain its usefulness in training students. Characteristics of high-risk patients are described, as well as opinions of users about the applicability of information presented and its relation to patient care. Approximately 3% of the patients seen were at risk of trauma from drug interactions, half of which were considered likely to occur. Implications of drug interaction data are also discussed in relation to treatment planning.

Challenges in geriatric oral health research methodology concerning caregivers of cognitively impaired elderly adults.

Little is known about oral health care behaviors of community-dwelling, cognitively impaired elderly (CIE) persons. Few studies have been conducted regarding the actual provision of oral care for CIE persons or the attitudes and concerns about oral health among their caregivers. The CIE person's ability to perform self-care decreases over time, and the role of the caregiver in daily oral care becomes increasingly important. The purpose of this pilot study was to explore the attitudes toward oral health and identify related concerns among caregivers who care for community-dwelling CIE persons. Caregivers were surveyed by means of a self-administered, mailed questionnaire. To maintain confidentiality, an intermediary was used for recruitment and data collection. Overall, 148 caregivers were invited by an intermediary to participate in the survey; only 21 (14%) consented to participate and returned the questionnaire. This paper discusses some of the numerous methodological challenges identified when an attempt was made to survey care-givers' attitudes toward and barriers to providing oral care for a dependent CIE.

Tobacco-related attitudes and counseling practices of Iowa dentists.

Evidence suggests that dentists' efforts to encourage their patients to stop tobacco use can significantly decrease tobacco-related morbidity and mortality. This study identified attitudes and counseling practices of 1116 Iowa dentists and compared results of a subgroup (N = 55) surveyed in both 1983 and 1989 to note changes in their tobacco-related attitudes and practices. Although only 9% of the dentists from the statewide survey felt counseling their patients on tobacco use was inappropriate, 56% reported they did not routinely ask their new patients about tobacco use. With some frequency 90% of the dentists discussed negative health effects of tobacco, whereas only 64% advised their smokers to quit. In addition, fewer than half made special efforts with pregnant patients or those at high risk for heart disease. The vast majority reported seldom if ever using intervention tools such as pamphlets or referral to cessation programs. Data from the subgroup surveyed in 1983 and 1989 indicated few substantial changes in attitudes and counseling practices. Substantial discrepancies exist between dentists' attitudes and counseling practices. Well-designed programs are needed to help dentists select and implement appropriate interventions.
