RESUMEN
Background: Sexually transmitted infections (STIs) are a significant public health concern worldwide, yet data on their prevalence and epidemiology, particularly in Central and Eastern Europe, remain scarce. This study aimed to assess the prevalence, anatomical localization, symptomatic/asymptomatic course, and co-infection patterns of STIs among men. Methods: This retrospective study analyzed data collected between May 2021 and July 2023, including sociodemographic, sexual behavior, and clinical data from 139 male participants. Molecular polymerase chain reaction (PCR) tests were conducted for Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Mycoplasma genitalium, and Trichomonas vaginalis. Results: Of the participants, 36% tested positive for at least one STI, with the urethra being the most common site of infection. NG and CT were the most prevalent infections. The majority of infections were asymptomatic, highlighting the importance of comprehensive screening, especially in high-risk populations like men who have sex with men (MSM). Conclusions: This study emphasizes the need for targeted screening strategies, particularly for extragenital STIs, and underscores the role of MSM in STI epidemiology. The findings highlight the importance of routine screening, even for asymptomatic individuals, to effectively control STI spread. Future research should validate and expand upon these findings to enhance STI prevention and management efforts.
RESUMEN
Dermatophytoses of the skin and scalp are common disorders in the pediatric population. The resemblance of the clinical presentation to other dermatoses can make fungal infections challenging to diagnose. We present three cases of dermatophytoses in children. The presence of fungi within skin lesions was confirmed in all cases. The diagnoses were "id" reaction in response to Trichophyton tonsurans infection, Kerion celsi because of Microsporum canis infection, and hair loss during microsporosis. Based on our review and clinical experience, we suggest diagnostic paths and treatments for dermatophytoses in children.

Vitiligo is an acquired chronic depigmenting disorder of skin. It is mostly asymptomatic and characterized by amelanotic macules and patches that affects 0.5% to 2% of the world's population. The etiology of vitiligo has not been clearly elucidated and multiple theories have been proposed regarding the causes of the disorder. Among the most prevalent theories, the genetic predisposition, oxidative stress theory, promotion of cellular stress and pathologic influence of lymphocytes T have been highlighted. As a result of increases in in-depth knowledge concerning the pathogenetic processes in vitiligo, we review the most recent information concerning its etiopathogenesis and treatment methods including topical and oral Janus kinase inhibitors, prostaglandins and their analogues, namely afamelanotide, Wnt/ß-catenin-signaling agonists and cell-based therapies. Topical ruxolitinib has been registered for vitiligo treatment, whereas other agents as oral ritlecitinib, afamelanotide and latanoprost have been studied in ongoing clinical trials. New highly effective therapeutic strategies may be developed thanks to molecular and genetic studies.

INTRODUCTION: There is growing evidence of the potential uses of dermoscopy in diagnostics of demodicosis. No previous studies have analyzed dermoscopic features in patients with ocular demodicosis. OBJECTIVES: To evaluate the potential usefulness of videodermoscopy in diagnostics of ocular demodicosis. METHODS: It was a single-center prospective observational study in which results of videodermoscopic examination of the eyelids were compared to the results of classic microscopic examination in patients with suspected ocular demodicosis and healthy volunteers. RESULTS: Study group included 16 women and 15 men. In fifteen (48.4%) patients, microbiological examination of epilated eyelashes was positive. The results of forms filled by the patients concerning known subjective clinical symptoms of ocular demodicosis revealed no significant differences between the group with positive and negative results of microscopic examination. The presence of Demodex tails and madarosis observed during dermoscopic assessment correlated positively with positive results of microscopic examination. At least one Demodex tail was found in 86.7% (13/15) cases with positive results of microscopic examination. In the two remaining cases microscopic evaluation showed the presence of Demodex brevis. In 37.5% (6/16) of patients with negative results of microscopic examination, videodermoscopy showed the presence of Demodex tails. CONCLUSIONS: Videodermoscopy may facilitate the diagnostics of ocular demodicosis. Patients reporting clinical symptoms suggesting ocular demodicosis but negative results of videodermoscopic examination should be referred to classical microscopic examination to exclude the presence of Demodex brevis. In patients with negative microscopic examination results and symptoms suggesting ocular demodicosis, dermoscopy-guided microscopic re-evaluation could be considered.
RESUMEN
The skin barrier defect in cutaneous T-cell lymphomas (CTCL) was recently confirmed to be similar to the one observed in atopic dermatitis (AD). We have examined the expression level of cornified envelope (CE) proteins in CTCL, AD and healthy skin, to search for the differences and their relation to the courses of both diseases. The levels of FLG, FLG2, RPTN, HRNR, SPRR1A, SPRR1B, SPRR3 and LELP-1 mRNA were determined by qRT-PCR, while protein levels were examined using the ELISA method in skin samples. We have found that mRNA levels of FLG, FLG2, LOR, CRNN and SPRR3v1 were decreased (p ≤ 0.04), whereas mRNA levels of RPTN, HRNR and SPRR1Av1 were increased in lesional and nonlesional AD skin compared to the healthy control group (p ≤ 0.04). The levels of FLG, FLG2, CRNN, SPRR3v1 mRNA increased (p ≤ 0.02) and RPTN, HRNR and SPRR1Av1 mRNA decreased (p ≤ 0.005) in CTCL skin compared to the lesional AD skin. There was a strong correlation between the stage of CTCL and increased SPRR1Av1 gene expression at both mRNA (R = 0.89; p ≤ 0.05) and protein levels (R = 0.94; p ≤ 0.05). FLG, FLG2, RPTN, HRNR and SPRR1A seem to play a key role in skin barrier dysfunction in CTCL and could be considered a biomarker for differential diagnosis of AD and CTCL. SPRR1Av1 transcript levels seem to be a possible marker of CTCL stage, however, further studies on a larger study group are needed to confirm our findings.
