Cross-sectional study of patients fitted with fixed partial dentures with special reference to the caries situation

Abstract – The caries situation among 30 patients with fixed partial dentures was examined 3 yr after cementation of the constructions. The fit of the crowns on the abutment teeth, the size of the interproximal areas and the relation between the crown margin and the gingival margin were registered. Risk factors for caries development, such as salivary factors, microbiologic factors, oral hygiene and diet were evaluated for each patient. During the 3-yr period 54 caries lesions occurred in 25 patients. Eleven lesions were found on abutment teeth. Two were located on the root surfaces unconnected with the crown margin (>2mm from the gingival margin), three were recurrent lesions, where the crown margin was located above the gingival margin but closer than 2 mm and six were recurrent lesions where the crown margin was located under the gingival margin. No single caries risk factor seemed to be so closely correlated to the number of caries lesions developed that it could be used alone to select of patients at risk. When the sum of the assumed negative factors was used, more caries was found among the patients with three or more factors with negative values in the group as a whole. However, predicting the development of caries in an individual case with a high degree of probability seems to be complicated. Generally speaking there was no indication that caries disease development was caused by the presence of the fixed partial denture per se.

Impact of Ganogerma applanatum extraction on haematological profiles of laboratory rats: a preliminary study in Nigeria

ObjectiveExtracts of Ganoderma species have been widely used as herbal medicines in the treatment of several infections. This study was carried out to ascertain the haematological properties of aqueous Ganoderma applanatum (G. applanatum).MethodsSixty albino rats grouped into six equal groups (10 each) of A to F consisting of tests and controls. Laboratory albino rats in groups A, B and C were infected with Trypanosoma brucei brucei (T. brucei brucei) while groups A and B (test) were treated with aqueous G. applanatum extract; other groups served as control. Microscopy and haematological profiles from the albino rats were monitored on daily basis for blood parasites, packed cell volume (PCV), haemoglobin concentration (HC), total red blood cell count (RBC), mean cell haemoglobin (MCH), mean cell volume (MCV), mean cell haemoglobin concentration (MCHC), and total white blood cell count (WBC).ResultsAlbino rats in groups A, B and C infected with T. brucei brucei and treated with various concentrations of aqueous G. applanatum showed a progressive reduction in PCV, HC, RBC, MCH and MCHC compared to the controls (P<0.05). All the infected rats died by day 14 of the experiment from parasitaemia.ConclusionsG. applanatum lacks ability to boost haematological profiles of anaemic laboratory rats and also of no use in the treatment of African trypanosomiasis. Higher doses of the fungal extract may be required to test on laboratory rats with less lethal biological stimulants of anaemia before proving or otherwise its true haematological properties.     

Body Temperature in General Population Samples

ABSTRACT Oral body temperature was measured in 816 men, 57 and 67 years old, sampled from the general population of Göteborg, Sweden, and 22 physically highly active men, sampled on clinical grounds. The measurements were taken in the morning for 14 months. After adding 0.3°C to the readings to make them comparable with rectal readings, the mean body temperature was 36.8±0.4°C. There was a seasonal variation with a peak during the winter and a trough during the summer. Body temperature was inversely correlated with height and positively correlated with weight and body fat but not with lean body mass. High physical activity and sensitivity to heat were associated with a higher than average body temperature. Sensitivity to cold was associated with a lower than average body temperature. Smoking prior to the measurements did not appear to affect body temperature.     

上海市康复服务现状调查

目的 了解上海市康复服务的现状。方法 对以往相关文献及政策查阅梳理。通过康复服务调查表对全市康复医院及设有康复医学科的医院进行业务数据收集。并进行了现场个案调研和访谈。结果 目前本市康复资源呈现面广点散、力量薄弱的总体特征,康复服务整体发展缓慢,供给不足,康复医护人员紧缺,康复从业人员队伍不稳定。结论 应树立“大康复”理念,大力充实各类康复资源,加快推进专业化康复机构的发展,制定符合康复服务特点、有利于康复机构发展壮大的医保、物价等配套政策,提高康复从业人员的地位和职业吸引力。
