BackgroundEpidemiology of (NG) infection remains inadequately understood.AimWe aimed to characterise NG epidemiology in Europe.MethodsWe used Cochrane and PRISMA guidelines to systematically review, report, synthesise and analyse NG prevalence data from 1949 to 30 September 2021. Random-effects meta-analyses estimated pooled prevalence. Meta-regression analyses investigated associations and sources of heterogeneity.ResultsThe 844 included publications yielded 1,573 prevalence measures. Pooled prevalence of current urogenital infection was 1.0% (95% CI: 0.7-1.2%) among general populations, 3.2% (95% CI: 1.8-4.8%) among female sex workers, 4.9% (95% CI: 4.2-5.6%) among sexually transmitted infection clinic attendees and 12.1% (95% CI: 8.8-15.8%) among symptomatic men. Among men who have sex with men, pooled prevalence was 0.9% (95% CI: 0.5-1.4%), 5.6% (95% CI: 3.6-8.1%), and 3.8% (95% CI: 2.5-5.4%), respectively, for current urogenital, anorectal or oropharyngeal infection. Current urogenital, anorectal or oropharyngeal infection was 1.45-fold (95% CI: 1.19-1.77%), 2.75-fold (95% CI: 1.89-4.02%) and 2.64-fold (95% CI: 1.77-3.93%) higher among men than women. Current urogenital infection declined 0.97-fold (95% CI: 0.96-0.98%) yearly, but anorectal and oropharyngeal infection increased (1.02-fold; 95% CI: 1.01-1.04% and 1.02-fold; 95% CI: 1.00-1.04%), respectively.Conclusions epidemiology in Europe has distinct and contrasting epidemiologies for vaginal sex transmission in heterosexual sex networks vs anal and oral sex transmission in MSM sexual networks. Increased transmission may facilitate drug-resistant strain emergence. Europe is far from achieving the World Health Organization target of 90% incidence reduction by 2030.

The microbiota of perianal abscesses is scarcely investigated. Identifying causative bacteria is essential to develop antibiotic therapy. However, culture-based methods and molecular diagnostics through 16S PCR technology are often hampered by the polymicrobial nature of perianal abscesses. We sought to characterize the microbiota composition of perianal abscesses via metagenomic next-generation sequencing (mNGS). Fourteen patients suffering from perianal abscesses between March 2023 and August 2023 underwent retrospective assessment. Information from medical records was used, including clinical information, laboratory data, and culture and mNGS results. Forty bacterial taxa were identified from perianal abscesses through mNGS, with (71.4%), (57.1%), and (50.0%) representing the most prevalent species. mNGS identified an increased number of bacterial taxa, with an average of 6.1 compared to a traditional culture-based method which only detected an average of 1.1 in culture-positive perianal abscess patients, predominantly (75.0%), revealing the polymicrobial nature of perianal abscesses. Our study demonstrates that a more diverse bacterial profile is detected by mNGS in perianal abscesses, and that is the most prevalent microorganism, potentially serving as a potential biomarker for perianal abscess.IMPORTANCEAccurately, identifying the bacteria causing perianal abscesses is crucial for effective antibiotic therapy. However, traditional culture-based methods and 16S PCR technology often struggle with the polymicrobial nature of these abscesses. This study employed metagenomic next-generation sequencing (mNGS) to comprehensively analyze the microbiota composition. Results revealed 40 bacterial taxa, with (71.4%), (57.1%), and (50.0%) being the most prevalent species. Compared to the culture-based approach, mNGS detected a significantly higher number of bacterial taxa (average 6.1 vs 1.1), highlighting the complex nature of perianal abscesses. Notably, emerged as a potential biomarker for these abscesses. This research emphasizes the importance of mNGS in understanding perianal abscesses and suggests its potential for improving diagnostic accuracy and guiding targeted antibiotic therapy in the future.

BACKGROUND A recently described zoonotic viral infection, mpox (monkeypox), is an Orthopoxvirus transmitted by close contact, which causes symptoms similar to smallpox, although less severe. This report presents the case of a 40-year-old man with anemia, proctitis, rectal bleeding, and a perianal rash due to mpox infection. CASE REPORT A 40-year-old man with a medical history of human immunodeficiency virus (HIV) and syphilis presented multiple times with progressive and painful perianal lesions. On initial presentation, swabbing of the lesions and polymerase chain reaction (PCR) testing confirmed a diagnosis of mpox infection, and treatment with a 14-day course of Tecovirimat was started. Nine days after initiating Tecovirimat, the patient presented again with worsening perianal pain and associated hematochezia resulting in acute symptomatic anemia. Despite a blood transfusion to treat his anemia, the patient's status declined as his viral symptoms progressed. Computed tomography (CT) investigation demonstrated significant proctitis with interval development of small perianal abscesses. A multidisciplinary approach for medical management and treatment was instituted. The resolution of the patient's anemia and mpox proctitis was confirmed on follow-up. CONCLUSIONS Despite treatment with antiviral agents, mpox infection can progress quickly; thus, swift management with a multidisciplinary approach and close follow-up is needed to treat and prevent secondary complications such as anemia and proctitis. Further data collection regarding the sexual practices of those with diagnoses of mpox as well as seminal, anorectal, and genital swabbing would be valuable to confirm the mode of transmission and cause of mpox proctitis.

Journal of the Anus, Rectum and Colon 2023The aim of this study was to evaluate the effectiveness of transperineal repair of secondary perineal hernia (SPH) using a mesh with a memory-recoil ring.
OBJECTIVES
The aim of this study was to evaluate the effectiveness of transperineal repair of secondary perineal hernia (SPH) using a mesh with a memory-recoil ring.
METHODS
Seven patients with SPH who underwent transperineal repair (TPR) between July 2010 and May 2022 were retrospectively analyzed. TPR was performed using a mesh with a memory-recoil ring.
RESULTS
All SPHs developed after abdominoperineal resections in patients with anorectal malignancies. The median longitudinal and transverse diameters of the hernia orifice were 8 (7-10) cm and 6 (5-7) cm, respectively. In all cases, the mesh was fixed to the ischial tuberosity, residual levator muscle, coccygeus muscle, and coccyx after thorough dissection of the sac. The median operation time was 154 (142-280) min. Perioperative complications occurred in 2 cases (29%). One was enterotomy, which caused postoperative mesh infection requiring extraction of the mesh. The other was vaginal injury, which resulted in vaginal fistula but closed spontaneously. The median postoperative length of stay was 9 (5-14) days. No recurrence was observed during a median follow-up of 35 (9-151) months.
CONCLUSIONS
TPR using a mesh with a memory-recoil ring is safe, feasible and promising technique for SPH repairs.

Infection and Drug Resistance 2023This paper aims to investigate the effect of Tounong San (TNS), a well-known traditional Chinese medicine prescription for suppurative infections, on the immune function.
PURPOSE
This paper aims to investigate the effect of Tounong San (TNS), a well-known traditional Chinese medicine prescription for suppurative infections, on the immune function.
METHODS
A suppurative infection model was established by injecting into subcutaneous tissue on the backs of rats. The expressions of CD68, CD163, CD31 and MPO in abscess tissues, phagocytosis rate and reactive oxygen species (ROS) of neutrophils in blood, phagocytosis function of peritoneal macrophages, and proliferation of blood lymphocytes, expression of IL-1, IL-6, CH50, TNF-α, IFN-γ, IgG, IgM in serum were detected at different time points.
RESULTS
On the 3rd day of medication, fibrinogen wrapped around the abscesses was visible in TNS groups, with an increase in new blood vessels and the expression of a large number of macrophages and neutrophils. On the 6th day, the pus of TNS groups diminished, and the number of new blood vessels reached its peak. On the 9th day, the abscesses disappeared in TNS groups, fewer new blood vessels, macrophages, and neutrophils were expressed, and more fibrocytes appeared and filled the original pus cavities. On the 3rd and 9th day of medication, the phagocytic rates of neutrophils and macrophages were significantly improved in TNS group, and the ROS content of neutrophils was increased on the 9th day. TNS has no effect on lymphocyte proliferation in vitro, but it can regulate the secretion of IgG and IgM by lymphocytes. TNS increases the level of IL-1, decreases the levels of IL-6 and TNF-α, and regulates the expressions of IFN-γ and CH50 in two ways.
CONCLUSION
TNS can form fibrinogen-wrapped pus to prevent bacterial infection from going deeper, and to improve the phagocytic function of phagocytes, the secretion of lymphocytes, and the defense function of the complement system. Therefore, it is a competitive drug for the treatment of suppurative diseases.

Open Forum Infectious Diseases Oct 2023No randomized controlled trial (RCT) has compared the impact on the resistome of ceftriaxone (CRO) plus azithromycin (AZM) vs CRO for the treatment of (NG).
BACKGROUND
No randomized controlled trial (RCT) has compared the impact on the resistome of ceftriaxone (CRO) plus azithromycin (AZM) vs CRO for the treatment of (NG).
METHODS
This was an open-label, single-center, RCT comparing the effect on the resistome of CRO plus AZM vs CRO for the treatment of NG. Men who have sex with men (MSM) with genital, anorectal, or pharyngeal NG infection were randomized into the CRO/AZM and CRO arms. Oral rinse and anorectal samples were taken for culture and resistome profiling at 2 visits (baseline and day 14). The primary outcome was the ratio of mean macrolide resistance determinants in anorectal samples from day 14 between arms.
RESULTS
Twenty individuals were randomized into the CRO/AZM arm and 22 into the CRO arm. We found no significant difference in the mean macrolide resistance determinants in the day 14 anorectal samples between arms (ratio, 1.05; 95% CI, 0.55-1.83; = .102). The prevalence of baseline macrolide resistance was high (CRO/AZM arm = 95.00%; CRO arm = 90.91%).
CONCLUSIONS
We could not demonstrate a significant effect of dual CRO/AZM therapy on the resistome compared with CRO alone, likely due to a high baseline resistance to AZM. Interventions to prevent the emergence of antimicrobial resistance in MSM are needed.

BackgroundIn France, lymphogranuloma venereum (LGV) testing switched from universal to selective testing in 2016.AimTo investigate changes in LGV-affected populations, we performed a nationwide survey based on temporarily reinstated universal LGV testing from 2020 to 2022.MethodsEach year, during three consecutive months, laboratories voluntarily sent anorectal -positive samples from men and women to the National Reference Centre for bacterial sexually transmitted infections. We collected patients' demographic, clinical and biological data. Genovars L of were detected using real-time PCR. In LGV-positive samples, the A gene was sequenced.ResultsIn 2020, LGV positivity was 12.7% (146/1,147), 15.2% (138/907) in 2021 and 13.3% (151/1,137) in 2022 (p > 0.05). It occurred predominantly in men who have sex with men (MSM), with rare cases among transgender women. The proportion of HIV-negative individuals was higher than that of those living with HIV. Asymptomatic rectal LGV increased from 36.1% (44/122) in 2020 to 52.4% (66/126) in 2022 (p = 0.03). Among users of pre-exposure prophylaxis (PrEP), LGV positivity was 13.8% (49/354) in 2020, 15.6% (38/244) in 2021 and 10.9% (36/331) in 2022, and up to 50% reported no anorectal symptoms. Diversity of the LGV genotypes in the Paris region increased during the survey period. An unexpectedly high number of genotype L1 variant was reported in 2022.ConclusionIn rectal samples from MSM in France, LGV positivity was stable, but the proportion of asymptomatic cases increased in 2022. This underscores the need of universal LGV testing and the importance of continuous surveillance.

Septic pulmonary embolism (SPE) represents the occurrence of septic thrombi in circulation, originating from an extrapulmonary infectious source. Perianal and perirectal abscesses are frequently encountered anorectal issues, often stemming from obstructed anal crypt glands, resulting in pus accumulation within the subcutaneous tissue and intersphincteric plane. Timely surgical drainage is essential upon diagnosis of anorectal abscesses. Adult males exhibit a twofold higher incidence of anorectal abscesses and fistulae compared to females, with common symptoms including excruciating anal or rectal pain. This case report details the presentation and management of a 42-year-old male patient afflicted by perianal abscesses that led to SPE. The report underscores the importance of recognizing and treating anorectal abscesses promptly to avert potentially life-threatening complications such as sepsis and fistulae.

The monkeypox (mpox) outbreak that began in May 2022 spread globally with a wide range of presentations. Mpox proctitis has been recognized as one of the severe forms of the virus during this outbreak. We present the case of a 33-year-old male with well-controlled HIV engaging in receptive anal intercourse presented with profuse rectal bleeding, tenesmus, and anal pain in July 2022. His symptoms persisted despite treatment for his rectal chlamydia with doxycycline. Rectal imaging with computed tomography demonstrated impressive inflammation. Contrast-enhanced images highlighted rectal wall thickening and submucosal edema. Diffuse lymphadenopathy of the anorectal region was also clearly seen. He received symptomatic treatment with tecovirimat resulting in the resolution of his symptoms and complaints. Subsequent rectal imaging displayed improvement and decreased inflammation. A better understanding of various presentations, imaging characteristics, and management is necessary to curb further dissemination.
