Domiciliary dental care (DDC) makes regular dental visits possible for people with different functional limitations who otherwise would not be able to access a dental clinic. DDC also facilitates cooperation with nursing staff. To our knowledge, the effect of DDC on oral health among elderly people in nursing homes has not been studied. As part of a project to establish recommendations for DDC, the aim of this randomized, controlled, single-blind, pilot trial with three parallel arms was to study the effect of professionally conducted oral care intervention, in domiciliary setting, on gingival bleeding on probing, dental plaque and oral mucosa. For three months, the participants were given either A) monthly professional DDC with oral care intervention, B) monthly individual oral care instructions, or C) oral care as usual. A total of 102 (n = 107) individuals completed the study. After three months, gingival bleeding on probing was significantly reduced among more participants in groups A and B compared with group C (p ntal plaque scores changed significantly over three months for group B compared with group C (p mucosal-plaque scores were significantly reduced in group A compared with both group B and C (p ntergroup differences were statistically non-significant. Compared with care as usual, professional DDC has the most favourable effect on gingival bleeding, whereas individual oral care instructions result in the highest reduction of dental plaque. Both professional oral care interventions and individual oral-hygiene instructions should be included in a domiciliary oralcare programme.

为了解道路对豹猫(Prionailurus bengalensis)空间生态和时间生态的影响,使用无线电追踪技术对6只雌性个体和4只雄性个体进行了为期1-18个月的监测。道路上的车辆主要在白天出现,似乎不影响豹猫的位置或活动,即便在周末或假期车辆增加时,情形也是如此。需要更多的研究来确定本文报道的结果是否代表了该物种的整体情况,或者仅仅特定于Kao Yai国家公园。

OBJECTIVE: To estimate the effectiveness of paracervical block in controlling pain among women treated with manual vacuum aspiration for an incomplete abortion mETHODS: A randomized clinical trial was conducted at nuestra Senora de Altagracia, a maternal and perinatal referral hospital in the Dominican Republic The sample size was based on a clinical difference of 1.5 points in the level of pain measured with the visual analog scale using 90%power and a sampling error of 0.04. Women who were at 12 weeks of gestation or less with an incomplete abortion were eligible to participate. They were randomly assigned to receive either the standard treatment of care (manual vacuum aspiration for uterine evacuation with psychological support but no paracervical block) or manual vacuum aspiration treatment with psychological support and paracervical block using 1.0%lidocaine. Patients with active infections, severe illnesses, psychiatric disorders, or allergies to lidocaine were excluded. Intraoperative pain as reported by the women and as documented by an external observer was measured. RESULTS: Although Ae paracervical block technique used showed a slight reduction in severe pain, there were no clinically or statistically significant differences in intraoperative pain between the 2 groups (relative risk 0.73; 95%confidence interval 0.43, 1.23) with 50%of all patients registering 7 or higher score on a visual analog pain scale of 0-10. However, statistically significant differences were found in each group when comparing the level of preoperative and intraoperative pain described by the patient (P manual vacuum aspiration technique and the paracervical Hock were not accompanied by complications. COnCLUSIOn: The paracervical block technique used in this study along with psychological support was comparable with pain control using psychological support alone; neither pain management regimen provided sufficient pain control. It is recommended that randomized comparat
