补充资料:常见的生殖感染及危害
淋病
是由淋病双球菌所致的泌尿生殖系统化脓性炎症性疾病。主要通过性交传染,急性淋病潜伏期一般为2—5天。当尿道感染时,症状为:尿道口红肿、灼痛、伴有尿频、尿急、尿痛、继而有黄绿色脓性分泌物,有异味;症状不明显者,易造成误诊、漏诊。症状持续两个月以上者称为慢性淋病,若不及时诊治,可引起合并症、后遗症。如前列腺炎、精囊炎、附睾炎、不孕不育,播散性淋病可引起败血症、关节炎、心内膜炎、心肌炎等。
非淋菌性尿道炎
主要是由衣原体、支原体等所致的泌尿生殖器炎症,主要通过性接触传播,潜伏期1—3周。临床症状与淋菌性尿道炎相似,但程度较轻,可有尿道刺痒、烧灼感和排尿疼痛,有浆液性或脓性分泌物,有的需要手挤压尿道才见有分泌物溢出,部分患者无症状,约有50病人初诊被忽略或误诊,约有20的患者同时有淋球菌双重感染,如治疗不彻底可引起附睾炎、前列腺炎,及Reiter氏综合症(关节炎、结膜炎、尿道炎)。
尖锐湿疣
系人类乳头瘤病毒(HPV)感染所致的生殖器、会阴和肛门部位的表皮瘤样增生。可通过直接或间接接触传染、潜伏期为1—12个月,平均为3个月。临床表现:初期为淡红色丘疹,渐次增大、增多、融合成乳头状、菜花状增生物、自觉症状不明显,或有痒感、灼热感和恶臭。尿道内尖锐湿疣可引起血尿、尿路梗阻等。
生殖器疱疹
由人类单纯疱疹病毒感染(HSV),其中约90由HSV-II,10由HSV-I引起,男性好发于包皮、龟头或冠状沟,偶尔发生在尿道,表现为:生殖部位出现红斑、痒、成群的细小水疱、疱壁薄、破后糜烂、形成小脓疱有烧灼感,有的形成溃疡,患者常感到疼痛,初次感染症状较重复发率高,一年内平均复发4次,生殖器疱疹有诱发生殖器癌的危险性,常给患者带来极大的心理负担。
软下疳
感染后大部分病例约在1周以内,有时可在数周以后发病。初发为外生殖器部位的炎性小丘疹。24-—48小时后,迅速形成脓疱,3—5天后脓疱破溃后形成溃疡,境界清楚。
梅毒
是由苍白螺旋体引起一种慢性全身性传染病。主要通过性接触传染,潜伏期长,本病表现极为复杂,可侵犯全身各器官,造成多器官的损害。
