Antimicrobial resistance in Neisseria gonorrhoeae in the UK: surveillance and management

Successful antimicrobial therapy is fundamental to the public health control of gonorrhea, in the absence of a protective immune response. Neisseria gonorrhoeae, the causative agent, has presented a constant challenge for the provision of such therapy as it has demonstrated the ability to become resistant to successive highly active agents chosen for first-line treatment. Acquisition of plasmids from other bacteria and long-term use of a single agent has selected both single step high-level and low-level resistance due to multiple mutations. While therapeutic failure of the current recommended agents cefixime and ceftriaxone begins to emerge, choice of alternative therapies is limited. Guidelines for therapy will be dependent on surveillance programs but individual patient management will require a viable organism to detect emerging resistance. Advances in molecular detection, while advantageous for the diagnosis of gonorrhea, fail to provide a viable organism, posing even greater challenges for the definition of treatment failure, and appropriate end points for test of cure. Innovative and collaborative approaches will be essential to maintain gonorrhea as a treatable infection.     

Is There a Weekly Pattern for Health Searches on Wikipedia and Is the Pattern Unique to Health Topics?

Background

Online health information–seeking behaviors have been reported to be more common at the beginning of the workweek. This behavior pattern has been interpreted as a kind of “healthy new start” or “fresh start” due to regrets or attempts to compensate for unhealthy behavior or poor choices made during the weekend. However, the observations regarding the most common health information–seeking day were based only on the analyses of users’ behaviors with websites on health or on online health-related searches. We wanted to confirm if this pattern could be found in searches of Wikipedia on health-related topics and also if this search pattern was unique to health-related topics or if it could represent a more general pattern of online information searching—which could be of relevance even beyond the health sector.

Objective

The aim was to examine the degree to which the search pattern described previously was specific to health-related information seeking or whether similar patterns could be found in other types of information-seeking behavior.

Methods

We extracted the number of searches performed on Wikipedia in the Norwegian language for 911 days for the most common sexually transmitted diseases (chlamydia, gonorrhea, herpes, human immunodeficiency virus [HIV], and acquired immune deficiency syndrome [AIDS]), other health-related topics (influenza, diabetes, and menopause), and 2 nonhealth-related topics (footballer Lionel Messi and pop singer Justin Bieber). The search dates were classified according to the day of the week and ANOVA tests were used to compare the average number of hits per day of the week.

Results

The ANOVA tests showed that the sexually transmitted disease queries had their highest peaks on Tuesdays (P<.001) and the fewest searches on Saturdays. The other health topics also showed a weekly pattern, with the highest peaks early in the week and lower numbers on Saturdays (P<.001). Footballer Lionel Messi had the highest mean number of hits on Tuesdays and Wednesdays, whereas pop singer Justin Bieber had the most hits on Tuesdays. Both these tracked search queries also showed significantly lower numbers on Saturdays (P<.001).

Conclusions

Our study supports prior studies finding an increase in health information searching at the beginning of the workweek. However, we also found a similar pattern for 2 randomly chosen nonhealth-related terms, which may suggest that the search pattern is not unique to health-related searches. The results are potentially relevant beyond the field of health and our preliminary findings need to be further explored in future studies involving a broader range of nonhealth-related searches.     

广东省汕头市92株淋球菌药物敏感性检测

天津地区女性生殖道感染病原学分析

目的:了解天津地区性病门诊和妇科门诊女性患者的细菌性阴道病(BV)及其他性病患病情况及相关致病因素。方法:根据Biswas标准对546例女性患者进行细菌性阴道病的诊断及相关致病因素调查,同时进行其他性病病原学、血清学及组织学检测。结果:细菌性阴道病在性病门诊就诊人群的患病率为27.2%,在妇科门诊就诊人群的患病率为22.0%,两者间差异无统计学意义(P>0.05);混合感染共83例(63.4%);合并感染最多的为解脲脲原体(29.8%);流产史、宫内节育器使用、有多个性伴3个因素与BV发生有相关性。结论:细菌性阴道病不仅是妇科常见病之一,也是与性传播有关的疾病,发病率高且常合并其他性传播病原体感染,故应在高危人群中积极开展筛查工作。     

Prevalence and manifestations of endometritis among women with cervicitis

Thirty-five women referred from a clinic treating sexually transmitted diseases, because of suspected cervicitis, were studied for the presence of endometritis by transcervical endometrial biopsies and cervical and endometrial cultures. Fourteen (40%) of the patients had histologic evidence of endometritis. Findings that significantly correlated with endometritis included a history of intermenstrual vaginal bleeding, the presence of Chlamydia trachomatis, Neisseria gonorrhoeae, or Streptococcus agalactiae in the cervix, and the presence of serum antibodies to C. trachomatis or to Mycoplasma hominis.     

Nonviral sexually transmitted infections

In spite of having standard diagnostic methods and effective treatment regimens, nonviral sexually transmitted infections continue to cause significant morbidity and mortality. Nonviral infections are of special concern in young populations and have more serious consequences in women than in men. With perinatal exposure, newborns are at risk for both minor and major complications, including congenital anomalies, mental impairment, and death. To make an impact on the serious sequelae associated with these infections, nurses must recognize common signs and symptoms, select appropriate diagnostic tests, and rapidly initiate effective treatment. Appropriate emotional support and effective counseling are important components of infection management.

男性泌尿生殖道非淋球菌奈瑟菌感染的诊断与治疗研究

目的:探讨非淋球菌奈瑟菌感染对男性泌尿生殖道感染诊断与治疗的影响。方法:采集8例急性尿道炎或慢性前列腺炎患者的尿道分泌物、前列腺按摩液或/和精液标本,分别接种淋球菌培养基、血琼脂培养基、沙保氏琼脂培养基和支原体培养基分离淋病奈瑟菌与其他细菌、真菌、支原体以及Gemenez染色检查衣原体。对分离的革兰阴性双球菌分别进行氧化酶、生化反应、药物敏感试验及淋病奈瑟菌核酸荧光聚合酶链反应(PCR)检测与鉴定。根据药物敏感试验结果选择和使用抗菌药物,对患者以静脉注射或/和口服治疗。结果:从8例患者前列腺按摩液或精液内分离的8株革兰阴性双球菌分别鉴定为粘液奈瑟菌3株、灰色奈瑟菌4株、嗜乳糖奈瑟菌1株,各菌株的隐蔽质粒pJD1基因PCR检测均表现与淋病奈瑟菌相似的阳性反应。男性生殖道分离的非淋球菌奈瑟菌具有多重耐药性,对喹诺酮类药物和磷霉素具有显著高的耐药性。静脉或/和口服给予病原菌敏感的头孢菌素或/和米诺环素治疗7d后,病原学复查无菌和患者症状消失。结论:寄生人体上呼吸道的某些正常菌群奈瑟菌也可以感染男性泌尿生殖器官,引起淋病样尿道炎与慢性前列腺炎。仅仅通过形态、氧化酶试验或/和检测隐蔽质粒基因以及其他淋病奈瑟菌非特异性核苷酸序列的PCR方法,可导致淋病的临床和病原学诊断错误。根据病原学检查结果选择药物静脉注射或/和口服,能够有效治愈非淋病奈瑟菌引起的急性尿道炎与慢性前列腺炎等男性生殖器官感染疾病,病原菌耐药性是影响治疗效果的主要因素。
