In a multicentre trial a single daily oral dose of indapamide 2.5 mg (Natrilix; Servier) was prescribed to 387 hypertensive patients by their general practitioners for a period of 12 weeks, the common protocol permitting adjuvant therapy where necessary. Excellent control was achieved in indapamide alone and in 51.2% of 123 patients with more severe hypertension who were treated with indapamide combined with other hypotensive agents. Non-limiting side-effects occurred in 0.03% of patients receiving indapamide alone. The drug is considered a safe and effective agent for the treatment of mild-to-moderate hypertension (diastolic blood pressure between 90 and 129 mmHg in private practice.
The diagnosis and treatment of oral mucosal lesions in HIV infected individuals is of importance. Oral lesions are reliable indicators of HIV infection and immunosuppression. They are important for staging HIV disease, they have been used as clinical markers in trials to test drug efficacy, and to determine the correct time for institution of treatment for HIV or prophylaxis against opportunistic infections. For the patients, they can cause pain, loss of taste and severe discomfort, leading to decreased quality of life. In more severe cases, they can disseminate and become life-threatening. Several types of lesions may affect the oral mucosa of HIV infected individuals. Although caused by different etiological agents, these lesions may have similar clinical appearance. They may also look like other oral mucosal lesions not commonly associated with HIV infection. Their correct diagnosis is important so adequate treatment can be prescribed. This article provides information to the dentist in private practice on how to elaborate a differential diagnosis and arrive to a final diagnosis of oral mucosal lesions in HIV infected individuals.
The purpose of this study was to identify the health education services provided by oral hygienists working in private dental practices. A questionnaire was designed, pilot tested and posted to all hygienists registered with the SAMDC. Thirty eight per cent returned the questionnaire. Results indicated that an average of only 6 to 10 minutes was spent on oral hygiene instruction per patient. The reasons given for this were identified as lack of time and resistance of patients to change their habits. Education procedures most often performed were the demonstration of brushing and flossing techniques. The least performed procedures included the use of disclosing agents and periodontal measurements. A statistical significant correlation was found between the number of patients consulted per day and salary paid by the dentist. Hygienists who earn more treat more patients per day, but do not spend less time on providing oral hygiene information. Patient resistance is an obstacle to oral hygiene instruction and more emphasis should be placed on the psychological approach to behavioural change than on techniques of oral hygiene. More time should be spent on oral health education and follow-up appointments should be scheduled to support patients in maintaining good oral health care.
The cumulative risk of developing colon cancer in patients with ulcerative colitis has been stated to increase 10%-20% for every decade of duration of disease after 10 yr. We reviewed the clinical course of 673 patients with inflammatory bowel disease restricted to the colon who were seen by the authors since 1955. A subset of 258 patients with a diagnosis of ulcerative colitis established before 1970 and followed by the authors was studied by both the classical life table and a generalized approach to estimate the risk of colorectal carcinoma. Only nine instances of colorectal carcinoma occurred. Using the former method and eliminating 3 patients referred with known colorectal carcinoma, the actuarial risk for developing this complication for all patients, regardless of extent of disease, was computed to be only 6.6% at 26 yr and 11.4% at 32 yr following the onset of ulcerative colitis. The cumulative probability of colorectal carcinoma among patients with universal colitis at 26 yr was 19.7% by the generalized method and 11.6% using the standard life table. The generalized approach consistently gave higher risk estimates due to a smaller number of patients in the denominator of the risk calculation. Using an alternative method, we calculated cancer risk from the date first seen for patients with universal extent and a history of greater than or equal to 10 yr of disease (means = 17.4 yr). The magnitude of the resulting colorectal carcinoma risk was even less than previously reported in hospitalized patients. This method is more suited for colorectal carcinoma risk assessment of a large series of ulcerative colitis patients seen in private practice and the results should modify the fear of cancer development in these patients.
In complying with the HIPAA security regulations, the large, multi-site academic radiology department is quite different from the small, private radiology practice. This article compares and contrasts the methods each of these two model organizations use to achieve compliance. In common between the two organizations is that complete documentation of the procedures and processes involved in data management must be prepared and reviewed. Although not required in the regulations, having the documentation conform to the regulation allows for easy monitoring, auditing, and certification of compliance by future independent bodies. The level to which each organization must secure their data, perform threat assessments, and implement security procedures and intrusion detection systems are very different. The regulations do not specify what level of due diligence is required. This must be determined by each organization using their own common-sense dictum. Although the solutions used by these two types of organizations may not be the same as those adopted by other radiology departments and practices, the approaches may still serve as useful templates to guide compliance efforts by others.

The French medical profession and health insurance organizations have jointly committed themselves to a concept termed the 'medical regulation' of care. They decided to promote the quality of health care, judging that an approach based on quality was the best option for reducing the increase in health costs. The Clinical Guidelines and Medical References programme was entrusted to ANDEM (Agence Nationale pour le Développement de L'Evaluation Médicale). Fifty working groups (669 experts) and 50 reading groups (1643 experts) met from June 1994 to November 1995 to produce guidelines. Learned societies were involved to propose experts. Hospital practitioners, doctors who specialized in the topic in question and those who did not had equal representation in the groups. The method consisted of a review of the literature to determine the level of scientific evidence. ANDEM's Scientific Council suggested modifications to the groups and agreed to disseminate 48 of the 50 texts. Careful observation of the operation of the groups identified factors that can positively influence the nature of the discussions and help avoid conflict: an abundance of high-quality literature, an understanding of clinical research methodology, the existence of guidelines from different institutions or different countries tending towards the same conclusions, good initial work carried out by the chairperson and the project manager, a limit to the number of questions asked of the group, the chairperson having good people skills and meeting-management skills, and an absence of professional and financial consequences for the participants. Good management of working groups is an additional factor in ensuring success. The regulatory medical references programme has led to changes of behaviour within the medical profession.
