RESUMEN
BACKGROUND: Mycoplasma genitalium (MG) is an emerging sexually transmitted infection, often harboring resistance-associated mutations to azithromycin (AZM). Global surveillance has been mandated to tackle the burden caused by MG, yet no data are available for Austria. Thus, we aimed to investigate the prevalence of MG, disease characteristics, and treatment outcomes at the largest Austrian HIV-and STI clinic. METHODS: All MG test results at the Medical University of Vienna from 02/2019 to 03/2022 were evaluated. Azithromycin resistance testing was implemented in 03/2021. RESULTS: Among 2671 MG tests, 199 distinct and mostly asymptomatic (68%; 135/199) MG infections were identified, affecting 10% (178/1775) of all individuals. This study included 83% (1479/1775) men, 53% (940/1775) men who have sex with men (MSM), 31% (540/1754) HIV+, and 15% (267/1775) who were using HIV pre-exposure prophylaxis (PrEP). In logistic regression analysis, 'MSM' (aOR 2.55 (95% CI 1.65-3.92)), 'use of PrEP' (aOR 2.29 (95% CI 1.58-3.32)), and 'history of syphilis' (aOR 1.57 (95% CI 1.01-2.24) were independent predictors for MG infections. Eighty-nine percent (178/199) received treatment: 11% (21/178) doxycycline (2 weeks), 52% (92/178) AZM (5 days), and 37% ( 65/178) moxifloxacin (7-10 days) and 60% (106/178) had follow-up data available showing negative tests in 63% (5/8), 76% (44/58) and 85% (34/40), respectively. AZM resistance analysis was available for 57% (114/199)) and detected in 68% (78/114). Resistance-guided therapy achieved a cure in 87% (53/61), yet, empiric AZM-treatment (prior to 03/2021) cleared 68% (26/38). CONCLUSIONS: Mycoplasma genitalium was readily detected in this Austrian observational study, affected predominantly MSM and often presented as asymptomatic disease. We observed a worryingly high prevalence of AZM resistance mutations; however, empiric AZM treatment cleared twice as many MG infections as expected.
RESUMEN
BACKGROUND AND OBJECTIVES: Serovar L1-L3 of Chlamydia trachomatis (CT) causes lymphogranuloma venereum (LGV). A surge in LGV-cases has been observed among HIV-positive men who have sex with men (MSM). Discrimination between LGV and non-LGV is pivotal since it has major treatment implications. Here, we aimed to determine the prevalence and characteristics of LGV among CT-infections. PATIENTS AND METHODS: All CT-positive results from 04/2014-12/2021 at the four largest Austrian HIV and STI clinics were evaluated. Disease characteristics and patient demographics were analyzed. RESULTS: Overall, n = 2,083 infections of CT were documented in n = 1,479 individual patients: median age was 31.4 years, 81% were male, 59% MSM, 44% HIV-positive, 13% on HIV pre-exposure-prophylaxis. Available serovar analyses (61% [1,258/2,083]) showed L1-L3 in 15% (192/1,258). Considering only MSM with rectal CT-infection, LGV accounted for 23% (101/439). Cases of LGV vs. other CT-infections were primarily MSM (92% [177/192] vs. 62% [1,179/1,891], p < 0.001), more often HIV-positive (64% [116/180] vs. 46% [631/1,376]; p < 0.001) and had frequently concomitant syphilis infection (18% [32/180] vs. 7% [52/749]; p < 0.001). LGV commonly manifested as proctitis (38% [72/192]) whereas 45% (87/192) were asymptomatic. CONCLUSIONS: Lymphogranuloma venereum accounted for 23% of rectal CT-infections in MSM. Furthermore, 45% of all LGV-cases were asymptomatic. In the absence of CT-serovar analysis, a high LGV prevalence should be considered in risk-populations and guide empiric treatment selection.

Syphilis is a curable systemic infectious disease with a clear increase in incidence in recent years. The disease presents with a broad clinical spectrum and challenges clinicians due to the long incubation period and the sometimes complex interpretation of serological test results. Penicillin G remains the treatment of choice in all stages of syphilis.

Necrobiosis lipoidica (NL) is a rare chronic granulomatous disease that manifests as sharply demarcated, telangiectatic, brownish-red plaques with atrophic yellowish centers prone to ulceration and occurs predominantly on the shins. In children, NL is extremely rare, but resistance to therapy, troublesome cosmetic appearance, painful ulcerations, and possible development of squamous cell carcinoma in long-persisting lesions are challenges during treatment. Our review includes 29 reports of NL in patients aged <18 years published from 1990 on PubMed, EMBASE, and Medline. The mean age of patients was 14.3 years, with a female predominance of 2 : 1 and a high prevalence of diabetes mellitus (80%). Data showed that potent topical steroids up to twice daily is the first-line treatment. For refractory cases, therapy can be switched to tacrolimus. Ulcerations benefit from phase-adapted wound care and anti-inflammatory medical dressings such as medical honey. Adding hyperbaric oxygenation to local or systemic therapy in difficult-to-treat ulcerated lesions can be considered. Refractory cases may be switched to topical photochemotherapy or systemic treatment with TNF-α inhibitors, systemic steroids (preferably in non-diabetic patients), pentoxifylline, or hydroxychloroquine. Necrobiosis lipoidica in childhood is difficult to treat, with a treatment failure rate of 40%. Therefore, further research through patient registries is recommended.
RESUMEN
BACKGROUND AND OBJECTIVES: This study analyzed the extent to which the recent introduction of more effective treatments has led to an improvement in real-world psoriasis patients. PATIENTS AND METHODS: Patient characteristics and the first-year treatment effectiveness in biologic-naive patients have been analyzed since 2004 until now, irrespective of treatment switches. RESULTS: Data from 2,729 patients were eligible for this analysis. The proportion of female patients increased significantly over the years from 29.9% to 36.2% (p < 0.028), while the number of patients with psoriatic arthritis declined from 36.6% to 30.0% (p < 0.001). Moreover, the duration of psoriatic disease and PASI at the start of the treatment significantly decreased. Last observation carrief forward (LOCF) analysis indicated that PASI 90 response increased from 18.9 to 44.6% at 3 months and from 32.9 to 66.8% at 12 months after treatment started. Similary, the PASI ≤ 3 rates increased from 33.2% to 66.0% at 3 months and from 41.9% to 78.9% at 12 months after the treatment started. CONCLUSIONS: The continuous introduction of more efficient biologics has led to significant improvements in patient care and clinical outcomes. Though one out of three to five patients, depending on the endpoint selected, nowadays still does not achieve an entirely satisfactory treatment response (i.e., PASI 90 or PASI ≤ 3).

Ulcerations of the prepuce or foreskin of the penis are rare in the day-to-day life of a urologist. The most common differential diagnosis is invasive penile cancer, which is why other diagnoses are often overshadowed. We report a case of a syphilitic lesion which was initially misdiagnosed as penile cancer. Considering the rising incidence of syphilis worldwide, syphilis should be considered as a possible cause of any solitary penile ulcer.

Urethritis is mainly caused by sexually transmitted pathogens, such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) [1]. Close to 90 million adults are infected annually with NG [2]. Treatment shall be performed according to national guidelines and resistance profiles [2, 3]. Enterobius vermicularis (EV) is the most common helminth in humans with 1 billion people globally infected [4-6]. Symptoms include anal pruritus; however, many infections are asymptomatic [4-7]. A case of urethritis due to simultaneous infection with NG and EV is reported.

Trichoblastic carcinosarcoma is a seldom biphasic adnexal tumor with malignant epithelial and mesenchymal components. The authors report the first tumor on the neck developed from preexistent trichoblastoma showing aggressive, recurrent behavior. An 82-year-old man presented with a solitary 3-cm exophytic lesion. Histology verified the diagnosis of trichoblastic carcinosarcoma. Four years earlier, a trichoblastic carcinoma arising in a preexisting trichoblastoma was excised at the same location. Despite successful surgical treatments, three local recurrences within 4 years were diagnosed. After the second relapse, the patient agreed on adjuvant radiation. Twelve months later, another relapse was excised in toto. In the last surgical specimen, only the mesenchymal component was found. Copy number variation analysis of the preexisting tumor and two recurrences revealed the same entity and additional chromosomal aberrations in the recurrences. Adnexal carcinosarcomas are seldom, yet presumably underdiagnosed biphasic tumors with aggressive growth potential. They should have adequate preoperative clarification with wide tumor excision, as radiosensitivity seems to be of limited effect.

The purpose of this mini-review was to provide the latest information and concepts on diagnosis and treatment of the most common sexually transmitted pathogens causing urethritis. The incidence of several sexually transmitted infections that cause urethritis is increasing, and this genitourinary syndrome is among the most common reason young men see clinical care. The authors performed a literature search including the currently valid guidelines, and an overview of the most relevant pathogens is given. Moreover, the authors developed a clinically applicable diagnostic and therapeutic algorithm, because early diagnosis and correct treatment can sometimes prevent infected individuals from significant morbidity. Future research will focus on new methods to combat pathogens that cause urethritis, including vaccination.
