炎症期拔除下颌智齿临床进展

下颌智齿冠周炎是口腔科的常见病和多发病,主要发生在18~30岁智齿萌出期的青年人。传统的冠周炎治疗是先行反复的冠周冲洗,重者需配合抗生素治疗,待炎症消退后拔除智齿。此法疗效肯定,但需多次就诊,疗程较长。对于一些待殊人群如部队官兵、弱残患者及工作忙碌的年轻人,反复就诊     

部队门诊就诊人员智齿发病率调查分析

智齿，在口腔临床学被称为第三磨牙，是口腔中最后萌出的牙齿，萌出年龄大约18～30岁，常常引起冠周炎及间隙感染而需要拔除，军队人员的主要年龄段正是智齿萌出的时期，智齿的发病率也相对较高，现就部队门诊就诊人员智齿发病率的情况进行分析。     

门诊就诊的部队人员智齿发病率调查分析

智齿，在口腔临床学被称为第三磨牙，是口腔中最后萌出的牙齿，萌出年龄大约18-30岁，常常引起冠周炎及间隙感染而需要拔除。军队人员的主要年龄段正是智齿萌出的时期，智齿引起的发病率也相对较高。本文对我院门诊2000年-2005年间部队就诊人员智齿发病率的情况进行调查分析。     

某部队团以下干部智齿情况调查

目的 调查部队干部智齿萌出及危害性情况。方法 对2005年5月我院到所保障的某部队对其干部进行口腔体检。并对智齿萌出及危害性情况进行分类列表分析。结果 主要年龄段正是智齿萌出的时期，绝大部分智齿萌出位置异常，造成多种并发症的发生（主要为急、慢性冠周炎，占85．45％），危害极大。结论 应对部队干部建立合理的口腔普查机制，对不正常及有隐患的智齿尽早进行预防性或治疗性拔除。

部队官兵智齿阻生位置及冠周炎发病情况调查

智齿冠周炎(pericoronitis of wisdom tooth,PWT)是指覆盖于正在萌出或部分阻生智齿牙冠表面和周围软组织的炎症,在颌面部炎症疾病中占了很大的比例,是口腔科的常见病。部队官兵的主要年龄段正是智齿萌出的时期,因此,部队因PWT所致非战斗减员情况时有发生。我院口腔科于2004年1     

焦虑抑郁状态对智齿冠周炎复发的影响

 目的 探讨焦虑抑郁状态对非外科手术治疗的智齿冠周炎复发的影响。方法 选择就诊于中日友好医院口腔医学中心的首发非外科治疗的智齿冠周炎患者,通过发放电子问卷收集如下信息:人口学信息、焦虑量表(GAD-7)和抑郁量表(PHQ-9)。半年后对随访患者的复发情况进行统计,采用多因素logistic回归分析智齿冠周炎复发与患者发病时情绪状态的关系。结果 共收集568份有效问卷,其中7.0%患者存在焦虑状态(GAD-7≥10),13.7%存在抑郁状态(PHQ-9≥10),半年后随访智齿冠周炎的复发率为11.4%。分析智齿冠周炎6个月后复发情况发现,男性的风险低于女性(OR=0.416,P＜0.05),焦虑增加了智齿冠周炎的复发风险(OR=1.124,P＜0.05)。结论 口腔医师应关注患者焦虑抑郁情绪状态,有助于智齿冠周炎的预防和治疗。     

Optimization of the system of medical service of students of Cadet Schools of the Ministry of Defense of the Russian Federation

One of the factors of the successful military career guidance Cadet schools students is preserving and promoting their health. Medical support of children and adolescents aged 10-17 years should include the full range of medical and preventive measures defined for this group. The state of providing outpatient care for pupils at the Cadet School in St. Petersburg was studied. These results show that full medical care in accordance with the standards can be based only on children's health clinics. It is important that the organization of medical support pupils cadet schools should be cooperate with civilian health care.

Estimation of accumulated dose of radiation by method of ESR-spectrometry of dental enamel of mammals

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P_1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method.     

Analysis of the results of the international comparison of activity measurements of a solution of Fe

The results of an international comparison of activity measurements of a solution of ⁵⁵Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a ⁵⁵Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.

The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison.     

Evaluation of the results of various technics of non-surgical therapy of varicocele

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood.     

延迟性脾破裂误漏诊原因分析

目的探讨延迟性脾破裂误漏诊原因和预防措施.方法回顾性分析总结12例延迟性脾破裂中的诊断和误漏诊的经验与教训.结果本组延迟性脾破裂的误漏诊5例(41.66%).对多发伤与脾破裂并存可能认识不足,外伤史轻微或伤员隐瞒外伤史,缺乏腹痛-缓解-突然再腹痛的典型病史,缺乏“对冲性脾破裂”力学分析和整体化诊断思路等为其误漏诊的主要原因.结论详细的外伤史和全面系统检查,重视腹以外多发伤掩盖腹内脏器伤及延迟性脾破裂可能.确立外伤-腹内脏器伤-脾破裂整体化诊断思路.不间断地辅以B超检查脾形态学变化和腹内有无积液,腹腔穿刺确定有无血腹、X线胸腹部检查观察左侧胸肋角和膈肌运动情况、必要时CT检查以尽早发现脾包膜下血肿,降低延迟性脾破裂误漏诊率.
