Topical application of fluorides on teeth

Abstract Prevention of caries in exposed root surfaces constitutes an important clinical problem. It is thus important that clinicians involved with periodontology have an insight into fluoride prophylaxis. The understanding of the cariostatic mechanism of fluoride has improved during recent years. The aim of the present review is to give a short account of the present concept. Calcium fluoride appears to be the only product which is formed on enamel, dentin or cementum during brief topical treatments with fluoride or use of toothpaste containing fluoride. This calcium fluoride is stable in the oral environment: this is contrary to what was believed until recently. The calcium fluoride constitutes a pH-dependant reservoir of fluoride which releases fluoride when pH drops. The practical consequences of this concept is discussed.     

Periodontal treatment needs in populations under 20 years of age in Espoo, Finland and Chiangmai, Thailand

The aim of this study was to assess the periodontal treatment needs at under 20 yr of age in the affluent area of Espoo, Finland, offering comprehensive public dental health care, as compared to a less advantaged area in Chiangmai, Thailand. In Espoo, 50 girls and 50 boys were examined in each age group of 7, 12 and 17 yr. In Chiangmai equal numbers of girls and boys were examined to obtain a group of 89 subjects aged 18.5 + 0.6 yr. According to the Community Periodontal Index of Treatment Needs (CPITN) the need of scaling increased in Espoo from 6% of the 7-yr-olds to 39% of the 17-yr-olds. Moderate pocketing (4-5 mm) occurred in one subject at age 12 and in three subjects at age 17. In Chiangmai, deep pockets (6 mm and over) were recorded for 1%, moderate pockets for a total of 44%, and dental calculus as the highest treatment need indicator in the remaining 55%, indicating a need for professional treatment in 100% of the group examined. The mean number of sextants requiring scaling was 0.6 per person at age 17 in Espoo as compared to 4.5 at 18.5 yr of age in Chiangmai. Three or more healthy sextants per subject were recorded for 47% of the 17-yr-olds in Espoo and for only 6% of the 18.5-yr-olds in Chiangmai. It was concluded that already at young age vast differences occur between periodontal treatment needs in industrialized and developing countries.     

A preventive intervention for enhancing resilience among highly stressed urban children

Describes the development and evaluation of a pilot 12-session, school-based preventive intervention designed to enhance resilience among inner-city children who have experienced major life stress. Thirty-six 4th–6th grade children participated in the intervention in groups of 5–8 co-led by school personnel. The curriculum focussed on understanding feelings in oneself and others, perspective-taking, social problem-solving, dealing with solvable and unsolvable problems, and building self-efficacy and esteem. Pre-post evaluation showed significant improvement among participants on teacher-rated indices of learning problems and task orientation and on child ratings of perceived self-efficacy, realistic control attributions and anxiety. Program limitations and factors that restrict generalization are considered and new directions for program development and research are proposed.     

Preventive Measures in Mite Asthma

To evaluate the effect of preventive measures 46 patients, all allergic to house-dust mites (Dermatophagoides spp.), were randomly allocated to a study and a control group. According to the patients' subjective recordings of symptom score and use of medicine, compared with the control group, the study group had improved. There was, however, no improvement when comparing the objective recordings of morning and evening peak flow and use of medicine, and it is concluded that the preventive measures in this programme are not very effective for patients allergic to house-dust mites. The reduction in indoor humidity in the study group was limited and, as a high indoor humidity is the cause of huge populations of house-dust mites in homes, it is emphasized that future programmes of preventive measures should focus more on damp problems, particularly those related to bad housing construction.     

Epistaxis

Epistaxis is a common problem that can affect the whole population. The majority of cases are self-limiting and do not require any medical intervention, but epistaxis can be associated with morbidity and even death in very rare circumstances. If epistaxis does not resolve with first aid measures, or episodes are frequent, patients may require specialist assessment and treatment by ENT, either in the outpatient clinic or via an unscheduled (emergency) admission to the hospital. Here, we provide an overview of the management of epistaxis in the outpatient setting and during an emergency admission in both paediatric and adult patients. We highlight the key considerations in the history and management, covering the common and rare conditions that are associated with epistaxis. This article provides an update from our previous article published in 2018 to include the more recent literature and a useful learning resource for examinations.     

Primary and preventive care in a university obstetrics and gynecology group practice

Objective: Our purpose was to determine whether primary and preventive care is practiced by a university obstetrician-gynecologist group practice.Study design: A retrospective chart review spanning 2 years of four academic physicians' private practices was performed. A total of 335 patients were reviewed with 739 patient encounters and 1032 patient problems identified. The definition of a primary care physician according to The American College of Obstetricians and Gynecologists was used to standardize data collection and evaluation.Results: Obstetric complaints accounted for 27.7% of all visits, whereas 65.4% were for gynecologic problems. Almost 7% of all complaints were neither obstetric nor gynecologic, and of those 74.6% were primary care problems completely managed by the obstetrician-gynecologist. Only 19.7% of these were referred for management. More than 89% of all encounters () involved some element of primary care.Conclusion: This study provides evidence that the majority of health care provided by the obstetrician-gynecologists is primary care.     

Neuroleptic malignant syndrome during low dosed neuroleptic medication in first-episode psychosis: a case report

 Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal side-effect of antipsychotic drug therapy, especially of dopamine receptor antagonists. As a dose relationship has been postulated, low dose neuroleptization would be expected to help to avoid this side-effect. In contrast, we report on a 21-year-old female following low dose fluphenazine treatment with 2.5 mg/day. The patient recovered from NMS after 3 days of dantrolene administration. Eventually, remission from psychotic symptoms was achieved with clozapine. At 8-month follow-up, psychopathology remained stable and there were no more signs of NMS.

论医疗纠纷处理技巧与防范程序的建立

近年来,医院发生医疗纠纷的频率有上升态势,处理纠纷难度亦日益加大,是医院管理者经常面临的难题。依据多年从事医院医疗质量管理的实践经验和相关资料分析认为:医疗纠纷增多的现象不仅与医务人员的医疗技术、服务态度、管理人员素质、管理作风和医院对纠纷处理的方式有关,与公民的社会保健知识和法律意识的增强等因素亦有相关性。令人满意的医疗纠纷处理办法在于是否能从错综复杂的医疗纠纷中寻找其发生、发展和解决的规律,处理医疗纠纷重在把握好三个基本原则和运用技巧。此外,认为解决纠纷与防范纠纷具有同等的重要性,并对医疗缺陷防范程序的建立以及在现代医院管理中的意义进行了初步探讨。
