Hypoglycaemia in insulin-treated Type 2 diabetes: frequency, symptoms and impaired awareness.

AIMS: Hypoglycaemia is considered to be less common in people with insulin-treated Type 2 diabetes than in Type 1 diabetes. A retrospective survey was made of 215 people with insulin-treated Type 2 diabetes to quantify the frequency and nature of hypoglycaemia experienced. METHODS: The frequencies of mild (self-treated) and severe (required assistance) hypoglycaemia during the preceding year were estimated retrospectively. The usual symptoms of hypoglycaemia and state of awareness of hypoglycaemia were scored using validated questionnaires and any history suggestive of impaired hypoglycaemia awareness was documented. RESULTS: In this cohort, 157 (73%) had experienced hypoglycaemia since commencing insulin, the frequency of which increased with duration of diabetes and of insulin therapy and was inversely related to current HbA1c (all P < 0.05). During the preceding year, 32 individuals (15%) had experienced severe hypoglycaemia, with an estimated incidence for the entire group of 0.28 episodes/patient/year. Principal components analysis revealed two underlying symptom groups (autonomic and neuroglycopenic), similar to those reported previously by young adults with Type 1 diabetes, but the total symptom score declined with advancing age. Of the 157 with a history of hypoglycaemia, the 13 (8%) individuals who gave a history of impaired awareness of hypoglycaemia had experienced a ninefold higher incidence of severe hypoglycaemia than those with normal awareness, and reported experiencing mainly neuroglycopenic symptoms. CONCLUSIONS: While the overall frequencies of mild and severe hypoglycaemia were lower in insulin-treated Type 2 diabetes than have been reported previously in Type 1 diabetes, the risk of hypoglycaemia was greater with increasing duration of diabetes and of insulin therapy. Although impaired awareness of hypoglycaemia was uncommon, it was associated with a higher incidence of severe hypoglycaemia.

The culture of special care units: an anthropological perspective on ethnographic research in nursing home settings.

Examining SCUs from an organizational cultural perspective requires an intraorganizational taxonomy of care settings, each with its own specific cultural framework for staff and resident behavior. Recognition of SCU cultural specifics allows for development of the best training curriculum for staff, means to maintain routine unit patterns, and a rationale for unit-specific distinctive features.

A model for Alzheimer's disease support group development in African-American and Hispanic populations.

Alzheimer's disease caregiver support groups were developed simultaneously in two southeastern cities with existing AD support groups but without ethnic minority use. The "ethic competence" concept, featuring targeted ethnographic methods, was applied in African-American and Hispanic communities in both sites. In 2 years, 114 ethnic minority primary caregiver and patient dyads were identified and African-American and Hispanic support groups were functioning.

Three-day clotrimazole treatment in candidal vulvovaginitis.

The accepted modern practice is to treat each sexually transmitted disease with the shortest possible course of treatment consistent with success. In candidal vulvovaginitis, six days is the minimum period that has so far been found to be successful, but we report here a further reduction to three days. Patients were given two clotrimazole pessaries nightly for three consecutive nights; the overall success rate was 89-4% one month after treatment. This compares favourably with the 93% cure rate reported with the six-day course of clotrimazole. With both the long and short courses, patients having their first attack of genital candidosis responded better than those with a history of previous infection. Short courses of clotrimazole treatment are particularly valuable in dealing with uncooperative women who stop treatment at the earliest possible moment. Clinical and laboratory diagnostic pitfalls and their possible influence upon the therapeutic outcome are also discussed.

The use of povidone-iodine ('Betadine') pessaries in the treatment of candidal and trichomonal vaginitis.

One hundred and thirty-five women suffering from trichomonal, candidal, or both infections simultameously, were treated with povidone-iodine pessaries, 2 pessaries being inserted nightly. Ninety-nine women were given a 7-day course of treatment, but the results obtained were disappointing, and the authors do not recommend such a regime for routine treatment. Better results were obtained with the recommended 14-day course. A further 36 women suffering from chronic trichomonal and/or canidal infections which had previously resisted orthodox treatment were given a prolonged 28-day course of pessary treatment. The results obtained were very encouraging, 92% of the trichomonal and 96% of the canidal infections being cured. Furthermore, although povidone-iodine is slightly less effective in trichomoniasis, most patients suffering from a chronic infection (candidal, as well as trichomonal) were cured by the one preparation. Side-effects did occur, but were significant in only 3 patients. Subjective symptoms, especially any offensive odour, disappeared within 3 days of the start of the treatment. The authors recommend that the 28-day course of povidone-iodine pessaries is used in those cases where trichomoniasis or candidosis has been a therapeutic problem in the past, particularly if the patient is currently on the oral contraceptive pill.
