Background Acne vulgaris is one of the most common cutaneous chronic diseases. The disease itself or the side effects of medications can play a crucial role in the development of sexual dysfunction. Aim Assessment of the occurrence of sexual dysfunction in female patients with acne vulgaris. Methods The study included 82 women diagnosed with acne vulgaris and 133 female controls without skin diseases. The sexual health of the subjects was assessed using the Female Sexual Function Index (FSFI) via an online anonymous questionnaire. Additional information regarding patients' medical history was analysed. Results There was no statistically significant difference in the total FSFI score between patients and controls (p > 0.05). Patients had significantly higher scores than controls in the satisfaction domain (p < 0.05). There was a positive correlation between the question about the subjective effect of skin condition on sexual desire and the likelihood of sexual dysfunction in the FSFI (p < 0.05, r = 0.33). Patients using retinoids had a slightly reduced FSFI (p = 0.44), which correlated negatively with retinoid use (p = 0.0428, r = -0.4257). Women receiving oral retinoids had downward trends in the satisfaction and pain domains (p = 0.41 and p = 0.198, respectively). Retinoid treatment was negatively correlated with the overall FSFI lubrication domain score (p = 0.0423, r = -0.4268). In addition, there was also a negative correlation between retinoid therapy and the overall FSFI orgasm domain score (p = 0.0024, r = -0.6014). Limitations The inability to evaluate the severity of acne vulgaris; the relatively small sample size; no matching of cases and controls with respect to age; and the lack of physician-confirmed data regarding the effectiveness of the administered treatment. Conclusions Some female patients with acne vulgaris may be at higher risk of sexual dysfunction. Decreased self-esteem and the general psychological burden of this dermatosis may negatively influence sexual functioning, so it is important to pay attention to this aspect. Patients who need help in this area should be referred to appropriate specialists.

Background Ageing is a degenerative process that affects the entire body. Skin ageing is characterised by a decrease in the levels of collagen, elastin fibre, and hyaluronic acid (HA), resulting in a loss of skin elasticity and hydration. Prior studies suggest that oral collagen supplements can help increase collagen, elastin, and HA levels, ultimately improving skin health. Objective To assess the impact of collagen-based supplements on the signs of skin ageing and determine the effective dosage. Methods This systematic review and meta-analysis utilized PubMed, Clinical Key, ProQuest, and Cochrane Library databases to identify studies published from 2010 to 2021. It includes ten randomised controlled trials (RCTs) with a total of 646 participants. Results The findings indicate that collagen supplements were statistically effective in increasing skin hydration (SMD 1.25 (CI: 0.77-1.74)) and elasticity (SMD 0.61 (CI: 0.21-1.02)). The most commonly administered dose was 4 g/day, with a median dose of 3.5 g/ day. Limitations Most of the studies could not control for weather-related factors. The findings are more applicable to females. Moderate heterogeneity (I2 = 55.5-56.5%) may limit generalisability. The risk of bias was generally unclear, and publication bias could not be assessed due to the small number of studies. Conclusion Oral administration of collagen supplement in a dose ranging from 1-10 g/day was statistically effective in increasing the skin hydration and elasticity.

Background The exact mechanisms underlying the eradication of the human papillomavirus (HPV) by cellular immunity remain obscure. Individuals with treatment-resistant warts frequently have immune deficiencies. Amino-peptidases (ERAP1, ERAP2) of the endoplasmic reticulum are essential for the production of antigenic epitopes that attach to the Major Histocompatibility Complex (MHC) class I and activate T-lymphocytes or natural killer (NK) cells. Aim To assess ERAP1 and ERAP2 serum concentrations in patients with resistant warts. Methods The current study included 200 subjects. They were split into 2 groups. Group (I) patients had resistant warts (n = 100), and group (II) age- and sex-matched subjects had a history of treated warts with no recurrence (n = 100). Clinical assessment and ERAP1 and ERAP2 serum level determination via ELISA were conducted. Results ERAP1 and ERAP2 levels were significantly lower in group (I) than in group (II) (p < 0.0001 for each). A significant positive relationship was observed between ERAP1 and ERAP2 (p < 0.001). A significant negative correlation was found between ERAP1, ERAP2, the number of warts, and a number of recurrences (p < 0.001). Limitations The small sample size, the lack of measurements of ERAP1 and ERAP2 before and after the treatment, and the exclusion of medical conditions such as diabetes mellitus and hypertension. Conclusion The current study findings highlight the potential utility of serum ERAP1 and ERAP2 as novel biomarkers for identifying patients with recalcitrant warts.

The gut microbiome and human body have co-evolved in a synergistic host-microbial relationship. The ideal composition of human gut microbiota is an elusive concept, but every individual has a unique gut microbiota profile with regional differences. Newer diagnostic techniques have helped identify different bacteria and their roles in health and disease. The gut microbiome composition is affected by various factors like age, diet, immune system, environmental factors, exercise, and drugs. The microbiome has varied roles in metabolism, immune response, immune tolerance and antimicrobial protection. Diet plays an important role in maintaining the gut microbial diversity. Loss of homoeostasis in the microbiome results in dysbiosis. Dysbiosis plays a role in many dermatological diseases like atopic dermatitis, psoriasis, acne, rosacea, hidradenitis suppurativa, connective tissue disorders and many other systemic conditions like obesity, diabetes, neurological disease and malignancy. Reconstitution of the gut microbiome ecology in the form of bacteriotherapy with the reintegration of certain strains of microbiota has a beneficial role in many of these disorders.
