Prevalence of new onset erectile dysfunction among Damietta governorate men after contracting COVID-19.

BACKGROUND: Several reports showed that sexual function was affected during and after the COVID-19 pandemic. AIMS: The objective of the study was to demonstrate whether a realistic association exists between the COVID-19 pandemic and erectile dysfunction (ED) among a sampled Egyptian population in Damietta governorate. METHODS: This cross-sectional study consisted of 330 adult males diagnosed with COVID-19 infection. They were categorized in three age groups (18-29, 30-39, and 40-50 years, respectively). COVID-19-confirmed cases were assessed by the Arabic version of the International Index of Erectile Function questionnaire (IIEF) scores. RESULTS: The prevalence of ED according to the IIEF was 55.1%. The ED was categorized into mild ED which represents 25.8% of the patients, mild to moderate which represents 22.4% of the patients, moderate which represents 7% of the patients, and severe which represents 0% of the patients. We found a significant negative correlation between the age of the patients and the IIEF score. Also, we found an association between the severity of COVID-19 infection and the IIEF score. CONCLUSION: An association of new-onset ED in men who suffered COVID-19 infection was established. This may be due to virus-induced endothelial cell dysfunction; however, an underlying mechanism and causation have not yet been clearly elucidated. While it appears that COVID-19 infection may be a risk factor for ED, additional research is needed to establish causality.

Hair disorders associated with post-COVID-19 infection in females: a cross-sectional study.

BACKGROUND: Coronavirus disease (COVID-19) currently named SARS-CoV-2 is a contagious disease caused by a coronavirus. The virus may infect the hair follicles directly or indirectly through systemic changes in the immune or hormonal systems. AIMS: In the current study we aimed to determine the prevalence of hair disorders in females infected with COVID-19. METHODS: Data was collected using a questionnaire covering four main domains: personal data, past medical history, COVID-19 history and treatment, and existence of any hair problems and their management. No identifier or sensitive data were collected. Those complaining of hair loss were subjected to complete general and local hair examination using trichoscopy to confirm hair loss. RESULTS: Hair problems were reported in 307 (61.4%) of COVID-19-infected female subjects. A total of 68.1% patients reported that hair loss existed and increased after COVID-19; 29.6% reported their hair problems only post-COVID-19 while 2.3% had hair shedding issues during infection only. The main reported hair problems were telogen effluvium (60.8%), increased gray hair (13.8%), seborrheic dermatitis (5.6%) trichotillomania (3.6%), and alopecia areata (2.2%). CONCLUSION: In conclusion, we reported prevalence of post-COVID hair fall that was confirmed by trichoscopy and which affected approximately 61.4% of infected females.

Fractional Carbon Dioxide Laser versus Trichloroacetic Acid 20% Peel in the Treatment of Acanthosis Nigricans: A Split Neck Comparative Study.

Background: Acanthosis nigricans (AC) is a common chronic skin disorder clinically presenting as velvety, hyperpigmented lesions that can affect any part of the body, including the face.OBJECTIVE: We sought to evaluate and compare the efficacy and safety of fractional CO2 laser and TCA 20% peel in the treatment of pseudo-acanthosis nigricans. Methods: The current study adopted an experimental, comparative split-neck design. It included a total of 20 patients with bilateral pseudo-acanthosis nigricans of the neck. Each patient was subjected to four sessions, spaced three weeks apart, involving fractional CO2 laser therapy on the right side and TCA 20% application on the left side. The evaluation of cases involved the utilization of the ANASI score and the assessment conducted by two dermatologists blinded to the treatment, both prior to and three months following the treatment. Results: Regarding Clinical improvement, 20% of the Fractional CO2 laser side had excellent improvement, and 45 percent had marked improvement. In contrast, the TCA 20% peel side had 2 percent marked improvement, 50 percent moderate improvement, and 40 percent mild improvement. In terms of response to therapy sessions, there was a statistically significant difference between the studied treatment sides (p<0.001). Regarding ANASI score differences between treated sides before and after treatment, a statistically significant reduction in ANASI score was observed, with a higher percentage of reduction in the Fractional CO2 laser side compared to the TCA 20% peel side. Limitations: The primary limitations are the small sample size and short follow-up period. Conclusion: In the treatment of pseudo-acanthosis nigricans, it appears that fractional CO2 laser and TCA 20% are promising, effective, and well-tolerated modalities. However, the Fractional CO2 laser was associated with a better response.

Intradermal injection of tranexamic acid versus platelet-rich plasma in the treatment of melasma: a split-face comparative study.

Millions of people throughout the world suffer from the acquired condition of hyperpigmentation known as melasma. Melasma is characterized by symmetrically oriented hyperpigmented macules and patches. Many treatment options are available with variable degrees of efficacy and tolerability. The aim of the work was to evaluate and compare the effectiveness and safety of intradermal tranexamic acid (TXA) versus intradermal platelet-rich plasma (PRP) in the treatment of various types of melasma. The current split-face prospective study included 40 cases with melasma. Tranexamic acid (TXA) was injected intradermally into the right side of the face by using a concentration of 4 mg/ml, while platelet-rich plasma (PRP) was injected intradermally into the left side. In both sides, a total of three sessions of treatment were provided, once every 4 weeks. Digital photographs were taken before each treatment session and 3 months after the last session. The modified melasma area severity index (mMASI) grading system and dermoscopy were used to assess the improvement in the condition. The disease severity and percentage of improvement were assessed by mMASI score before and after therapy across both sides of the face. along with determining the degree of satisfaction and side effects among the included cases. The mean mMASI score before therapy in the TXA side was 4.59 ± 2.87, while in the PRP side, the mean mMASI score before therapy was 4.72 ± 2.72 with no statistically significant difference between the two sides (p = 0.841). After 3 months of treatment, the mean mMASI score in the TXA-treated side was 2.49 ± 1.58 with a mean percentage of decrease of 45.67 ± 8.10%, while in the PRP side, the mean mMASI score after treatment was 2.17 ± 1.41 with a mean percentage of decrease of 53.66 ± 11.27%. There was a high statistically significant decrease in the mMASI score after treatment on both sides (p < 0.001); however, the percentage of score reduction in the PRP side compared to the TXA side was statistically higher. Intradermal injection with PRP revealed higher efficacy in the treatment of melasma as compared to TXA injection with no significant difference regarding the associated side effects.

Comparative study between topical application of triamcinolone acetonide after fractional carbon dioxide laser versus microneedling in the treatment of resistant alopecia areata.

Alopecia areata (AA) is a disease that affects the psychological well-being of the affected individuals. Laser-assisted drug delivery and microneedling (MN) are promising methods for the treatment of different dermatological diseases. The aim of the study was to compare the efficacy of topical application of triamcinolone acetonide after fractional carbon dioxide laser versus MN in the treatment of resistant AA from a clinical and dermoscopic perspective. Thirty patients were randomly divided into two groups of 15 patients each: the Laser group received fractional CO2 laser treatment followed by topical application of triamcinolone acetonide, and the MN group received dermapen treatment followed by topical application of triamcinolone acetonide. In our study, we found no statistically significant difference between the studied groups before and after treatment, except for black dot, which is higher in the MN group than in the laser group (46.7% vs. 13.3%). There is a statistically significant difference between the studied groups in terms of treatment response at the first follow-up, with 13.3% of the laser group seeing terminal hair regrowth compared to 0 in the MN group after 12 weeks. Regarding the degree of improvement, there was no statistically significant difference between the laser group and the MN group. The use of fractional CO2 laser and MN for transepidermal drug delivery (TED) allowed for more uniform drug distribution. There was no significant difference between the two treatment methods in terms of their high effectiveness in the treatment of resistant AA.

Prevalence of female sexual dysfunction among diabetic females: a cross-sectional case controlled study.

BACKGROUND: Sexual relationships, sexual functions are all parts of the female sexual identity and which influence physiological, psychological, and reproductive functions of women. AIM OF THE WORK: The study aimed to identify prevalence of Female Sexual Dysfunction (FSD) in women affected by type 1 and type 2 Diabetes Mellitus (DM) and to evaluate the impact of diabetes on female sexuality. PATIENT AND METHODS: This cross-sectional study was carried out on 400 married females who were interviewed to answer Female Sexual Function Index (FSFI) questionnaire and were divided into two groups: the first group included 300 diabetes patients (134 patients with type 1 DM and 166 patients with type 2 DM), while the second included 100 women not diagnosed with diabetes who served as controls. RESULTS: Considering female sexual dysfunction (score < 26.55), there was statistically significant increase of patients with female sexual dysfunction (FSD) in Type 1 DM (50.7%) when compared to type 2 DM patients (28.9%) or control group (10.0%). CONCLUSION: FSD is a significant health problem in premenopausal women complaining of DM. Females with type 1 DM were more affected than females with type 2 DM, who in turn were more affected than healthy controls. Long duration of the disease was the main risk factor for developing FSD.

Implications of Serum Anti-Ceramide Antibodies and Interleukin 4 on Nerve Damage and Physical Impairments Among Leprotic Patients: A Case-Controlled Study.

BACKGROUND: Leprosy is a chronic granulomatous disease affecting skin and nerves with a range of clinical and immunological responses. OBJECTIVES: The study aimed to identify levels of IL-4 and antibodies to ceramide in the sera of leprosy patients and healthy subjects using enzyme linked immunosorbent assay (ELISA) to evaluate their possible role in disease severity and their correlation to nerve involvement and physical impairments. METHODS: This study included 25 patients with multibacillary leprosy, 25 with paucibacillary, and 25 healthy controls who were subjected to history taking, clinical examination, and identification of sites and morphology of skin lesions, nerve examination, eye examination, as well as sensory examination. Slit skin smear examination was used for diagnosing paucibacillary (PB) and multibacillary (MB) leprosy cases. Anti-ceramide antibody (ACA) and IL-4 titers were estimated and correlated with the type of leprosy, disease duration, nerve damage, and disabilities. RESULTS: Serum ACA and IL-4 levels were significantly higher in MB than its level in PB leprotic patients and controls. A significant positive correlation was established between nerve affection; physical impairments and serum levels of ACA and IL-4. CONCLUSION: Levels of ACA and IL-4 can impact nerve affection in leprotic patients and can serve as potential biomarkers of disease progression J Drugs Dermatol. 2022;21(3):284-291. doi:10.36849/JDD.5543.

Topical hydrogen peroxide solution 40% in treatment of plane wart.

BACKGROUND: There are various available therapies for plane warts; however, no specific therapy has been established as entirely effective. OBJECTIVE: The aim of work was to assess the effectiveness and safety of topically hydrogen peroxide (HP) 40% solution in treating the plane warts. SUBJECTS AND METHODS: The study included 30 patients diagnosed clinically as plane warts. Topical HP 40% was applied with a single-use wood end of a cotton swab soaked with the solution to minimize filtration of effective drug to the surrounding areas. Duration of the treatment was planned to be 4 sessions for each lesion with 2-week interval and a 3-month follow-up period after treatment completion to detect any recurrence. RESULTS: Complete clearance of plane warts was observed in 27 (90%), and there was no recurrence of the lesions after a 3-month follow-up period. CONCLUSION: HP solution especially the 40% concentration may be considered a promising line of treatment for non-genital warts. It is a very effective, safe, cheap, and easy-to-use new topical treatment for non-genital warts.

Microneedling-assisted topical tranexamic acid solution versus 4% hydroquinone for treating melasma: A split-face randomized study.

BACKGROUND: Melasma, also known as chloasma or mask of pregnancy, is a common, acquired, hyperpigmentary disorder usually affecting females. Tranexamic acid (TA), a derivative of amino acid lysine, has shown promising results over the past few years when used along with other therapies and when used as a stand-alone therapy. AIM OF THE WORK: In this study, we aimed to evaluate and compare the effectiveness of topically applied tranexamic acid after microneedling versus topically applied hydroquinone (HQ) 4% alone in patients with melasma. PATIENTS AND METHODS: Fifty selected patients were divided randomly according to the random number allocation method into two groups (25 patients each) of A (topical 4% hydroquinone, nightly application) and B (microneedling + topical 4% TA, every other week). RESULTS: After eight weeks of treatment, the mean modified MASI score of the HQ treated side changed from 6.604 ± 4.02 to 3.032 ± 1.19 with a mean decrease percentage of 54.8% ± 19.4%. This reduction in modified MASI score was found to be statistically significant, (p < 0.001). MASI score of group B (TA +microneedling) changed from 6.348 ± 3.84 to 3.712 ± 1.19 with mean decrease percentage of 57.4% ± 23.4% which was also statistically significant, (p < 0.001). CONCLUSION: We demonstrated safety and efficacy of both used modalities and with minimal side effects. Topical HQ application achieved minimal non-significant higher satisfactory results among raters and subjects.

Intralesional Candida antigen versus intralesional vitamin D3 in the treatment of recalcitrant multiple common warts.

BACKGROUND: There are various therapies available for recalcitrant common warts; however no specific therapy has been established as entirely effective. AIMS: To assess the efficacy and safety of intralesional Candida antigen injection of vs. intralesional vitamin D3 injection in the treatment of multiple recalcitrant common warts. PATIENTS AND METHODS: A total of 80 adult patients with multiple common warts were randomly assigned to one of three groups in this study. Thirty patients were assigned to Group I, who received a 0.3 ml intralesional injection of Candida antigen. Thirty patients were assigned to Group II, who received a 0.6-ml (60 000 IU) intralesional injection of vitamin D3. Twenty patients were in Group-III, who received 0.3 ml of normal saline as a control. Each agent was injected at the base of largest wart every 3 weeks until full clearance has been obtained, or for a maximum of four sessions. RESULTS: In the Candida antigen, vitamin D3, and saline groups, complete wart clearance was observed in 76.7 percent, 20%, and 0.0 percent, respectively. The side effects were negligible and transient, and there was no recurrence of the lesions. CONCLUSION: Intralesional injection of Candida antigen is as a safe, simple, cost-effective treatment modality for multiple recalcitrant common warts and it outperforms intralesional vitamin D3.

Calprotectin in acne vulgaris: A possible contributory role.

BACKGROUND: Acne vulgaris (AV) is a common inflammatory skin disease involving dysfunction of the pilosebaceous unit. Many mechanisms for the pathogenesis of acne have been postulated; however, the precise pathogenesis is still uncertain. AIM: Evaluation of the level of serum calprotectin in patients with AV and its correlation with the different clinical variables of the disease, particularly severity. PATIENTS AND METHODS: This is a case-control study that included ninety subjects who were subdivided into two groups; group I, which included sixty patients complaining of AV with different grades of severity, and group II that included thirty apparent healthy age and sex-matched participants as a control group. Severity of AV was determined according to the Global Acne Grading System (GAGS). Serum calprotectin level was measured in both patients and controls by the enzyme-linked immunosorbent assay (ELISA) method. RESULTS: A highly statistically significant difference in the serum calprotectin level was found between patients with AV and control subjects. A highly significant positive correlation was found between the serum calprotectin levels and the severity of acne. Similarly, a significant positive correlation was found between serum calprotectin levels and the duration of the disease. CONCLUSION: Serum calprotectin levels are increased in acne patients and are positively correlated with its severity.
