Only a few cases of pityriasis rosea (PR)/pityriasis rosea-like eruption (PRLE) after anti-SARS-CoV-2 vaccination have been reported. In the period May 2021-February 2022 we observed five cases of clinically typical PR that appeared 2 to 3 weeks after anti-SARS-CoV-2 vaccination with BNT162b2 (3 patients) or mRNA-1273 (2 patients). In 4 patients PR appeared after the first vaccination; in one patient after the second one. In 3 patients a biopsy for histopathological examinations was carried out. Results were typical for PR. In all patients laboratory examinations were with-in normal ranges. All patients were treated with cetirizine. Complete remission was observed within 14-30 days. Four patients were subjected to the second vaccination, but no skin lesions appeared. All patients are currently in good general health. It is possible that a relationship between anti-Sars-CoV-2 vaccination and PR/PRLE exists; however, it is very rare, in consideration of millions of vaccinated subjects and the low number of reported cases of PR/PRLE. The pathogenesis of this relationship is unknown. However, some hypotheses may be advanced: PR/PRLE following anti-Sars-CoV-2 vaccination may be just a coincidence; anti-Sars-CoV-2 vaccines cause a reactivation of HHV-6 and/or HHV-7; vaccines can induce a delayed hypersensitivity response clinically similar to drug-induced PRLE.

Introduction: Neisseria gonorrhoeae (NG) antimicrobial susceptibility trends to azithromycin, cefixime and ceftriaxone were analyzed, from 2009 to 2016, to monitor changing antimicrobial susceptibility concomitant with the change in prescribing practice in 2012 from cefixime, or ceftriaxone, to ceftriaxone plus azithromycin. Patient characteristics predictive to be infected by antibiotic resistant N. gonorrhoeae were estimated. Finally, the protocol for the treatment of gonorrhoea, in comparison with the international guidelines, was also evaluated. Materials and methods: Data on NG antimicrobial resistance were obtained from a network of sexually transmitted diseases clinics and other laboratories in 12 cities in Italy. We tested the 1,433 gonococci for antimicrobial susceptibility to azithromycin, cefixime and ceftriaxone using a gradient diffusion method. Logistic-regression methods with cluster robust standard errors were used to investigate the association of resistance categories with demographic and clinical patient characteristics and to assess changes in prescribing practices. To minimize bias due to missing data, all statistical models were fitted to data with forty rounds of multiple imputation, using chained equations. Results: The percentage of isolates resistant to cefixime was 17.10% in 2009 and declined up to 1.39% in 2016; at the same time, those resistant to azithromycin was 23.68% in 2009 and 3.00% in 2012. Starting from 2013, azithromycin resistant gonococci tended to increase up to 7.44% in 2016. No ceftriaxone resistant isolates were observed. By multivariate analysis, the men who have sex with women (MSW) and women had a proportional adjusted OR of resistance of 1.25 (95%CI: 0.90; 1.73) and 1.67 (95%CI: 1.16; 2.40), respectively, in comparison with men who have sex with men (MSM). An aOR of resistance of 0.48 (95%CI: 0.21; 1.12) among NG isolated in the pharynx, compared with those isolated in genital sites, was calculated. The proportional aOR of resistance was 0.58 (95%CI: 0.38; 0.89) for presence vs absence of co-infection and 2.00 (95%CI: 1.36; 2.96) for past history vs no history of gonorrhoea.Finally, at least for the period 2013–2016, the older, subjects with anorectal or pharyngeal gonorrhoea infection, subjects with a co-infection, subjects with a previous gonorrhoea infection were not always correctly treated. Conclusions: Overall, our findings suggest the shifts in N. gonorrhoeae susceptibility to cefixime and azithromycin in the time frame period. First of all, the increasing rate of azithromycin resistance in 2015–2016 in NG isolated in the country need to be monitor in the future. Finally, extensive information on treatment regimens may be useful to asses treatment adherence particularly for the older subjects, subjects with an anorectal or pharyngeal infection, subjects with a co-infection and subjects with a previous history of gonorrhoea. Gonorrhoea treatment strategy should be based on the evidence obtained by the local antimicrobial surveillance system and data about treatment failures. [ABSTRACT FROM AUTHOR]

A quiz concerning the diagnosis of the 29-year-old Egyptian warehouse man who was presented with a six-month history of multiple papular nodular lesions on limbs, erosions on his legs and erythematous plaque on left wrist.

The article presents a case study of a 24-year-old circumcised man presented with an ulcerative lesion on the penis which had been present for 3 days and reported that the lesion had appeared after sexual intercourse with his girlfriend. His clinical examination revealed an ulcerative and crusted posthitis with multiple ulcers, penile oedema and bilateral inguinal lymphadenopathy. He was diagnosed with penile ulceration due to silicone injections.

A medical quiz about the diagnosis of an older patient with vegetating nodules after dental erosions is presented.

The article presents case studies heterosexual man and bisexual man due to the painless, indurated ulcerative lesions of the oral mucosa known as syphilitic chancre. The patients underwent several examinations and found out that they engaged in unprotected receptive orogenital contact with different partners. The patients were treated with intramuscular benzathine penicillin G 2.4 million units and the disease becomes negative after three months.

The article discusses a study of lichen sclerosus et atrophicus (LSA) disease that involves the genital area. It references a research published in the "Acta Dermato-Venereologica." Topics discussed include the diagnosis and histopathology of LSA, link of LSA to the development of squamous cell cancer (SCC) in men and women and steroidal cream as the first line therapy for LSA.

An introduction to the journal is presented in which the editors discuss the subject of venereology and the role of dermatologists in the field.

Molecular analyses of mip and ompA genes were performed on 20 Neisseria gonorrhoeae isolates. The genes were present with a high degree of conservation in all strains. Sera from patients with urethritis or disseminated gonococcal infections were able to recognize the purified Neisseria gonorrhoeae macrophage infectivity potentiator (Ng-MIP) and Neisseria gonorrhoeae outer membrane protein A (Ng-OmpA).
