口腔检查

Examinationoftheoralcavityispartofeverygeneralphysicalexamination.Oralfindingsinmanysystemicdiseasesareunique,aresometimespathognomonic,andmaybethefirstsignofthedisease.Earlydetectionoforalcancermaybepossible.口腔检查是全身检查的一部分.在许多系统性疾病中,口腔表现是独特的,有时是病征性的,可以是疾病的首先征兆.口腔癌的早期发现是可能的.

经常的,自发的,大量出血,表示血液病.反复出现的口腔感染,可能存在糖尿病（此为最常见原因）,粒细胞缺乏症,中性粒细胞减少症,白血病,免疫球蛋白缺乏病或白细胞功能紊乱.免疫抑制者可经历口腔单纯疱疹的疼痛反应,并伴有口腔溃疡而导致妨碍摄食.

Athoroughevaluationrequiresgoodillumination,atongueblade,gloves,andagauzepad.Adentalorlaryngealmirror,ifavailable,ishelpful.全面的评估需要良好的照明,压舌板,手套和纱布垫.口镜或咽喉镜有助于口腔检查.

然后巡检硬软腭,悬雍垂和口咽部.请患者尽快地伸出舌,暴露舌背,并且尽快地向每侧移动舌,这样就可看到舌的后侧表面.如果患者不能将舌伸出足够以使轮状乳头能被看见时,检查者可用纱布垫拉住舌尖,使其伸出到所需的体位.然后巡检舌腹部表面和口底,再检视牙齿和牙龈.

盗汗

首先要排除发烧引起的出汗。

发烧性出汗应另行诊断。

20世纪前，盗汗通常提示有结核菌感染。

现在，其他很多不适都与此症状相关。

盗汗通常是某已知病症的标志，如糖尿病（特别是伴夜间低血糖者）、癌症、头外伤和各种风湿病。

盗汗也可能是新的疾病的一种症状，在给盗汗报告病人进行检查时，需检查既往病史及新的症状。

II.History.Nightsweatscanbecharacterizedbydeterminingonset,frequency,exacerbations,andremissionsofsymptoms.Questionpatientsaboutthecurrentstateofknowndisorders.Excessivesweatingisassociatedwithpoornocturnalglycemiccontrol.Flaresofrheumatologicdisorders（rheumatoidarthritis,lupus,juvenilerheumatoidarthritis,andtemporalarteritis）causesweatingtoo.Pregnancytemporarilychangestheintrinsicthermostatinmanywomenwhoperspireexcessively.Patientswhoareimmuno-compromisedareatincreasedriskforinfections,especiallywithatypicalagents.Patientswithahistoryofsubstanceabuseneedtobeaskedaboutneedleuseandcontaminants.II.病史。

盗汗可通过确认发作时间、次数、加剧及症状消退加以确定。

询问病人已知疾病。

多汗也与夜间血糖控制不良有关。

风湿性疾病（如类风湿关节炎、狼疮、幼儿性类风湿性关节炎、颞关节炎等）也导致出汗，妇娠也会暂时的改变很多妇女的体温状况，导致出汗过多。

免疫代偿病人感染风险增加，特别是非典型性病原体感染。

有药物滥用史病人需询问其针头使用及其他接触状况。

A.Reviewofsystems.Othersymptomsthatcanaccompanynightsweatsincludeflushing（carcinoidsyndrome,pheochromocytoma）,jointpain,sleepapnea,menstrualirregularities,reflux,cough,headache,dysuria,dyspnea,rashes,fatigue,palpitations,andweightandbowelhabitchanges.A.系统检查。

伴随盗汗的其他症状包括潮红（类癌综合症、嗜铬细胞瘤）、关节痛、睡眠性呼吸暂停、月经不调、反流、咳嗽、头痛、排尿困难、睡眠困难、皮疹、疲乏、心悸及体重与排便习惯改变。

询问最近免疫及新药使用情况，如抗抑郁剂、胆碱能药、哌替定、雌激素抑制剂、促性腺激素抑制剂、烟酸、类固醇、兴奋剂、非处方制剂、解热剂和自然疗法。

询问病人有无接触性传染病（STD）、HIV、肝炎、结核病，有否职业性及旅游相关性接触。

也应询问周围夜间体温总体变化增多情况。

C.Psychologicalfactors.Anxiety,nightmares,andpsychoactivepreparationscanprecipitatenightsweatsinhealthyindividuals.C.精神因素。

焦虑、噩梦及兴奋剂可导致健康个体盗汗。

有遗传疾病及可能的恶性肿瘤家庭史病人应进行适当的筛检。
