淫羊藿（苷）对男性生殖系统的作用和机制

淫羊藿是一种常用的中药材,淫羊藿苷是从淫羊藿中提取的一种黄酮类化合物,也是淫羊藿中最主要的活性物质。研究发现,淫羊藿苷具有促进成骨细胞的生成和活化、调节免疫、抗衰老和抗炎等多种功能。临床上淫羊藿（苷）用于治疗生殖系统、骨关节系统、呼吸系统、神经系统、心血管系统和免疫系统等多种疾病。淫羊藿（苷）对男性生殖系统的作用及机制主要包括具有雄性激素样作用,促进睾内睾酮的合成和分泌。淫羊藿（苷）通过改善精子发生的微环境、增强睾丸抗氧化作用促进精子生成,增加精子密度,改善精子活力,减缓生殖衰退。此外,淫羊藿（苷）可促进阴茎勃起,治疗勃起功能障碍及早泄。     

CO2点阵激光联合伊可尔治疗难治性掌跖疣疗效观察

目的观察CO₂点阵激光联合伊可尔治疗难治性掌跖疣的临床疗效及安全性。方法:选取掌跖部多发,经其他疗法治疗后复发的难治性掌跖疣患者58例,患者平均分为两组,对照组29例先选择激光功率0.5-2W将皮损磨削薄直至焦痂或点状出血,之后采用CO₂点阵模式10-20mJ/cm2治疗,每周治疗一次,连续治疗4周。观察组29例观察组:CO₂点阵激光治疗仪器及治疗方法与对照组相同。激光治疗完毕,使用伊可尔药水棉片湿敷患处2小时,激光治疗后连续湿敷伊可尔棉片5天,停药2天至下一次激光治疗后继续湿敷,连续治疗4周。2组均随访观察6个月。结果:58例患者均完成治疗,治疗4周后,观察组总有效率93.10%,病损清除率为77.82%,均高于对照组的72.41%、60.81%,组间差异均有统计学意义(P<0.05)。6个月后,观察组复发率10.34%,对照组复发率37.93%,组间差异有统计学意义(P<0.05),两组不良反应差异无统计学差异。结论:CO₂点阵激光联合伊可尔治疗难治性掌跖疣疗效优于单用CO₂点阵激光。联用伊可尔降低了难治性掌跖疣的复发率,并且操作简便,安全性高。     

Presentación atípica de infección por virus de herpes simple tipo ii (VHS II) refractaria a tratamiento con aciclovir en 2 pacientes hematológicos

Herpesvirus infections are not uncommon in hematologic patients. Our first patient, diagnosed with chronic lymphatic leukemia, presented extensive genital herpes infection refractory to treatment with aciclovir and with a partial response to foscarnet, which had to be withdrawn due to systemic adverse effects. The second patient, diagnosed with follicular Hodgkin lymphoma, presented hypertrophic herpes infection refractory to treatment with aciclovir but that responded to intralesional cidofovir and topical imiquimod. As in other immunocompromised patients, herpesvirus infection in hematologic patients can present atypical manifestations, as well as resistance to treatments that are activated by the viral thymidine kinase. A high level of clinical suspicion is therefore needed to make an early diagnosis, together with extensive knowledge of the different treatments available.     

Preschool Girl With Vaginal Bleeding Due to Pinworm Endometritis

Genital tract bleeding in prepubertal girls is a rare clinical condition, which can occur for multiple reasons. It frequently generates anxiety in the family and in health care professionals. A thorough anamnesis and careful genital inspection can give important diagnostic hints; however, there are cases in which the cause remains doubtful and a complete gynecological evaluation (including cultures and vaginoscopy) is necessary. Therefore, the attending physician should always consider less frequent diagnoses in order to perform the necessary studies in a sequential and rational manner. We present the case of a preschool girl with vaginal bleeding due to pinworm endometritis, which, to our knowledge, has never been reported before as a cause of genital bleeding in prepubertal girls.     

胎膜早破孕妇血清炎性标志物变化､生殖道感染情况及羊膜腔感染危险因素分析

目的研究胎膜早破(PROM)孕妇血清炎症标志物水平变化?生殖道感染情况及引起羊膜腔感染的可能相关因素,并分析引起PROM的危险因素。方法将2017年6月至2020年6月台州市中心医院收治的113例PROM患者纳入观察组,同期正常妊娠并分娩的120例孕产妇纳入对照组。比较两组血清炎性标志物[血管细胞黏附分子-1(VCAM-1)?C反应蛋白(CRP)]及下生殖道感染情况,并行单因素及多因素Logistic回归分析影响PROM的独立危险因素;分析PROM孕产妇的羊膜腔感染情况,分析血清炎性标志物?生殖道感染与羊膜腔感染的关系。结果观察组血清炎性标志物VCAM-1?CRP水平及下生殖道感染率均显著高于对照组(P<0.05);多因素Logistic回归分析显示,下生殖道感染?血清VCAM-1水平?血清CRP水平及双胎妊娠均是影响PROM的独立危险因素;统计发现,PROM合并羊膜腔感染者共31例,其血清VCAM-1水平?血清CRP水平及下生殖道感染率均显著高于非羊膜腔感染者(P<0.05)。结论下生殖道感染?血清炎性标志物水平升高及双胎妊娠是PROM发生的独立危险因素,且下生殖道感染及炎性标志物水平升高还可能是影响羊膜腔感染发生的因素之一。     

Chronic mucocutaneous anogenital herpes: series of ten cases and literature review

Anogenital herpes is one of the most prevalent sexually transmitted infections worldwide. It has several clinical manifestations, from cases of primary herpes infection to recurrent forms, among them chronic mucocutaneous herpes. This presentation is rare, characterized by a duration of more than four weeks, usually associated with immunosuppression and resistance to classic anti-herpetic treatment. The present study presents a series of ten cases of chronic mucocutaneous herpes with a discussion about its clinical, laboratory, and therapeutic aspects.
