RESUMO
BACKGROUND: Women have polycystic ovarian syndrome (PCOS) at higher rates than any other endocrine condition with an average incidence rate of 6 to 8%. Acne is an immune mediate common condition frequently affecting adolescents and adults and is often associated with PCOS. The objective of the study was to assess the impact of oral isotretinoin on ovarian functions of acne patients suffering from PCOS. Forty women with a clinical diagnosis of acne as well as PCOS participated in this prospective clinical trial. Participants were given oral doses of isotretinoin ranging from 0.5 to 1 milligram per kilogram (mg/kg), for a total of 120 to 150 mg/kg. To establish baseline values of hormone levels, on days 2-5 of the menstrual cycle, venous blood samples were obtained. Moreover, global acne grading system (GAGS), follicle count, and bilateral ovarian volumes were evaluated both before and after isotretinoin treatment. RESULTS: A significant reduction in global acne score from pre-treatment levels to post-treatment levels was observed (11.58 ± 5.857 vs. 1.65 ± 1.369). Ovarian volume was significantly reduced from 10.26 ± 1.539 before treatment to 8.74 ± 1.436 after treatment on the right side (P < 0.001) and from 11.08 ± 1.564 before treatment to 9.36 ± 1.479 after treatment on the left side (P < 0.001). A significant reduction in free testosterone level and hirsutism scores were observed after treatment (P < 0.001; P < 0.01 respectively. CONCLUSION: Isotretinoin may exert beneficial effects in hyperandrogenic women with PCOS and needs to be further evaluated by large multicentre controlled trials.

Alpha-lipoic acid (ALA) is a natural short chain fatty acid containing sulfhydryl groups generated from octanoic acid and cysteine in the mitochondria, and is found in both the aqueous and lipid phases. The present study aimed to assess the efficacy of ALA supplementation in primary infertile males complaining of idiopathic asthenozoospermia. Eighty patients were randomly allocated to treatment group A (n = 40) and control group B (n = 40) groups, receiving daily doses of 600 mg (divided into two daily doses of 300 mg each) of alpha lipoic acid (ALA) or an identical placebo for 90 days. Semen analysis, anthropometric and total antioxidant capacity were analysed and compared before and after treatment. Daily supplementation with ALA improved total motility and progressive motility of the spermatozoa. In the ALA-treated group, sperm motility and progressive motility increased significantly, similarly, the mean percentage of sperm vitality demonstrated a significant increase among the ALA treated group (p < 0.001). Analysis revealed a statistically significant increase in semen volume and sperm concentration in the ALA supplemented group, while abnormal morphology decreased significantly (p < 0.001). ALA supplementation significantly improved sperm parameters and functional tests in group A patients. ALA supplementation in patients with idiopathic asthenozoospermic thus enhanced sperm quality and viability, which could therefore be considered as an adjunct therapy pending further verification of its association and mechanisms involved.
RESUMO
BACKGROUND: Cutaneous warts are frequent conditions that possess much challenge to treat. OBJECTIVE: To verify the potential role of vitamin D in the pathogenesis of viral warts by measuring the serum levels of vitamin D in patients diagnosed with viral warts compared to healthy controls and to verify whether oral vitamin D supplementation of those vitamin D-deficient patients would result in wart clearance. METHODS: To evaluate the serum vitamin D levels, the study recruited 80 subjects, including 40 patients diagnosed with viral warts and 40 age- and sex-matched healthy controls. All patients were subjected to detailed history taking and examination to detect duration and type of warts. Serum vitamin D levels were measured using ELISA. RESULTS: Thirty-five percent of patients had sufficient vitamin D levels (54-90 nmol/L), and 40% of patients had insufficient levels (50-80 nmol/L), while 25% of them had deficient levels (<50 nmol/L). In healthy group, 30% had sufficient levels, and 45% had insufficient levels, while 25% had deficient levels. There was an insignificantly lower serum level of vitamin D as well as an insignificantly deficient vitamin D status among patients compared to healthy controls. CONCLUSION: Vitamin D serum levels appear to be lower among viral wart patients, and oral supplementation studies need to be more intensely investigated before elucidating its role; if any, in wart clearance.

BACKGROUND: Acrochordons (fibroepithelial polyps, skin tags, papillomas) are common benign neoplasms of the skin. AIM: To identify the prevalence of colonic polyps among patients presenting with skin tags and to determine a useful criteria for screening with colonoscopy. METHODS: Two hundred patients who fulfilled the selection criteria underwent physical, biochemical evaluation (fasting blood sugar (FBS), body mass index (BMI) calculation, occult blood in stool), and histopathological examination of the skin tags. Colonoscopy was performed in patients with positive blood in stool, and any polyps identified were resected or biopsied. RESULTS: Occult blood in stool was insignificantly detected in 12 (6%) of the 200 subjects (p < 0.001), and they were referred for colonoscopy. A prevalence rate of 3.5% was reported, and of twelve colonoscopies performed, three patients were polyp-free, two were diagnosed with ulcerative colitis (UC), and seven patients were diagnosed with polyps that were removed and/or biopsied (p = 0.421). Of the seven polyps, three were hemorrhoidal polyps and the four other polyps were adenomatous polyps (villous adenoma). CONCLUSION: The mere presence of skin tags does not significantly correlate with existence of colonic polyps and does not justify screening colonoscopy unless other metabolic, GIT, and biochemical markers are identified.

BACKGROUND: Psoriasis is a chronic inflammatory hyper proliferative skin disease. Angiogenesis play an important role in Psoriasis pathogenesis, occurring even before plaque formation. Angiopoietins play an important role in angiogenesis and hence are described as angiogenic factors. AIMS: To evaluate serum levels of angiopoeitin 2 (Ang-2) following treatment with narrowband ultraviolet B (NBUVB) in patients with moderate-severe plaque psoriasis and correlate it to psoriasis area and severity index (PASI). PATIENTS/METHODS: This cross sectional study included 38 patients complaining of moderate to severe plaque psoriasis and 38 healthy controls. Psoriasis area and severity index (PASI) was determined and was correlated to serum levels of Ang-2 before and after treatment with NBUVB. RESULTS: PASI scores and serum values of angiopoietin 2 demonstrated a significant difference between the baseline and at the end of the 12 weeks NBUVB treatment. A statistically significant positive correlation was established between psoriasis severity and Ang-2 serum levels before and after treatment. CONCLUSION: The study demonstrated a potential contribution of Ang-2 in the pathogenesis of psoriasis, as well as its usefulness as a biomarker of psoriasis severity.

BACKGROUND: Granulocyte-macrophage colony-stimulating factor (GM-CSF) is believed to play an important role in the development of acne vulgaris. AIM OF THE WORK: To investigate the presence of GM-CSF 3928C/T and GM-CSF 3606 T/C promoter gene polymorphisms in Egyptian acne patients. METHODS: To examine whether GM-CSF single nucleotide polymorphisms (SNPs) are associated with susceptibility to acne vulgaris (AV), we investigated the genotype and allele frequencies of the SNP 3928C/T and 3606T/C of the GM-CSF gene in 100 Egyptian acne patients (29 with mild acne, 38 with moderate acne, and 33 with severe acne) and 100 controls, using a PCR restriction fragment length polymorphism (RFLP) method. RESULTS: There was a highly significant difference in genotype and allele frequencies of the 3928C/T group between patients with acne vulgaris and controls for the SNP site. Regarding the 3606 T/C subgroup only a marginal significant difference was found between cases and controls in TC pattern (p = 0.039); with the TC genotype appearing more in cases (53% of patients) than controls (35% of healthy controls). CONCLUSION: We report a novel GM-CSF 3928C/T promoter gene polymorphism contributing to the pathogenesis of acne in Egyptian population.

BACKGROUND: Warts, or verrucae, are mucosal human papilloma virus (HPV) infections that are very challenging to treat. OBJECTIVE: To compare the safety and efficacy of intralesional injection of vitamin D3 versus intralesional injection of candida albicans antigen for plantar warts. METHODS: Forty patients were included in the study and were divided into two groups (A&B) with 20 patients each. Group A received intralesional vitamin D3 while Group B received intralesional Candida antigen. Injection was done every 3 weeks until clearance of warts or a maximum of three treatments. RESULTS: Nine patients showed complete clearance in group A (45%), while 6 patients (30%) showed partial response and no response in 5 patients (25%) of group (A). As for group (B), complete clearance of the treated warts was observed in 8 patients (40%), partial response in 6 patients (30%) while no response was observed in 6 patients (30%). No superiority of one treatment to the other was observed nor was any statistical significance in both groups’ responses noted. CONCLUSION: Treatment of multiple warts by intralesional injection of candida antigen or vitamin D3 is safe and effective, with good cure rates, has an excellent safety profile, with minimal recurrences and statistically equivalent. J Drugs Dermatol. 2021;20(5):546-549. doi:10.36849/JDD.5264.

BACKGROUND: Pumpkin (Cucurbita pepo L.) is an annual climber plant, and its seeds have considerable amount of oil with nutritional and medicinal importance. AIM: The present study aimed to investigate the clinical efficacy of pumpkin seed oil (PSO) in the treatment of female pattern hair loss (FPHL) and compare its effects with minoxidil 5% foam. METHODS: Patients with FPHL were randomly assigned to pumpkin seed oil (n = 30; group A) or minoxidil 5% foam (n = 30; group B) for a period of 3 months. Patients were evaluated clinically and dermoscopically at baseline, at one and half months, and at the end of the 3-month study. RESULTS: Among group A (pumpkin seed oil) candidates, a significant decrease was observed in hair shaft diversity before and after treatment (30.5 ± 6.2%, 24.0 ± 4.02, P < .001, respectively) as well as in the vellus hairs (22.5 ± 4.9, 15.8 ± 2.2, P < .001, respectively). Upright regrowing hairs significantly increased from (0.13 ± 0.5) before treatment to (0.9 ± 1.0) after treatment (P < .001). In group B (minoxidil applying) candidates, a significant decrease was observed in hair shaft diversity before and after treatment (31.5 ± 6.3%, 21.3 ± 2.2, P < .001, respectively) as well as in the vellus hairs (24.7 ± 6.4, 19.5 ± 5.4, P = .02, respectively). Conclusion Findings of the present trial provide evidence of a promising potential role of PSO in treating FPHL.

BACKGROUND: Androgenetic alopecia (AGA) is the most common form of alopecia in men. Cetirizine, a second-generation H1 blocker, is known for its anti-inflammatory properties and its ability to decrease prostaglandin D2 (PGD2) production. AIM: To evaluate the efficacy and tolerability of topical cetirizine in male patients with AGA. METHODS: Two groups of 30 patients each (healthy males aged between 22 and 55 years) with different grades of AGA classified according to the Hamilton-Norwood classification were recruited for this study. Group A subjects applied 1 mL of 1% topical cetirizine daily, while group B subjects served as controls and were instructed to apply 1 mL of a placebo solution for 6 months. RESULTS: Dermoscopic assessment revealed significantly higher hair regrowth among the cetirizine-treated group (P < .001). The patients' satisfaction was significantly higher among the cetirizine-treated group (P < .001). CONCLUSION: The current study highlights a potential role cetirizine might have in treating AGA. It should be noted that studies are lacking in this regard and more randomized and controlled trials are warranted in order to confirm or refute such early findings.

BACKGROUND AND OBJECTIVES: Striae distensae (SD) is a challenging skin condition. Striae alba (SA) represents the chronic late atrophic stage of SD. Fractional laser technology is among the modalities used for treating SD. Lately, fractional microneedling radiofrequency (FMR) is gaining increased popularity in treating SD. The aim of our study was to assess and compare the efficacy of FMR and fractional Er:YAG laser in the treatment of SA. STUDY DESIGN/MATERIALS AND METHODS: Twenty female patients were enrolled in the study fulfilling all inclusion and exclusion criteria. On a randomly selected half side of the body, the patients were treated with 2940 nm fractional Er:YAG laser while the other half side was treated with the FMR. RESULTS: Both modalities showed a significant reduction in the width of the widest striae (P < 0.005); however, there was no significant difference between them. Using optical coherence tomography, all patients demonstrated a mean significant increase in epidermal thickness; however, the FMR-treated sites showed significantly better results when compared with the ER:YAG-treated sides (P = 0.029). Scar improvements in both modalities did not correlate to skin type, duration, or site of the striae. CONCLUSION: Er:YAG and FMR represent two safe, effective, tolerable modalities for treating SA and are associated with minimal side effects. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

BACKGROUND: Cutaneous warts are frequent conditions that possess much challenge to treat. OBJECTIVE: To evaluate safety and efficacy of intralesional injection of tuberculin purified protein derivative (PPD) antigen injection vs MMR (mumps, measles, rubella) antigen for the treatment of multiple warts. METHODS: The study included 90 Patients who were divided into three groups (A, B, and C). Each group consisted of (30) patients. Group (A) subjects received intralesional PPD injections. Group (B) subjects received intralesional MMR antigen injection and Group (C) received intralesional saline injection. RESULTS: Full clearance of warts was observed in 18 (60%) of patients in group (A) (70%) vs 24 patients (80%) in group (B). Distal warts completely disappeared in 18 (60%) of patients in group A and 12 (40%) of patients in group B. Infrequent side effects including pain, erythema, and minimal induration were reported in both groups. CONCLUSION: We established a good safety and efficacy profile for tuberculin PPD and MMR antigens in resistant wart treatment.

BACKGROUND: Androgenetic alopecia (AGA) is a condition affecting both males and females. Aims We aimed to assess the demographic and clinical features of early-onset AGA among smokers and nonsmokers and to evaluate whether prevalence of AGA was affected by smoking. PAATIENTS/METHODS: One thousand (1000) healthy males aged between 20 and 35 years not complaining of any local scalp condition and free of any mental illness were recruited for this study and divided into two groups of 500 each based on their smoking attitudes. Androgenetic alopecia was classified according to the Hamilton baldness scale, and trichoscopy was used to confirm the diagnosis of AGA. A designed questionnaire to determine basic physical and smoking habits completed and results was interpreted and analyzed. RESULTS: The majority of smokers (425) had a form of AGA, while only (200) nonsmokers had a degree of AGA (P < .01). Of the smokers group, 235 (47%) had grade III AGA and 120 subjects (24%) had grade IV AGA. In the nonsmokers group, 100 subjects (20%) had grade II AGA and 50 subjects (10%) had either grade III or IV AGA. CONCLUSION: The prevalence of AGA among smokers was statistically higher than among nonsmokers, while severity of AGA was not associated with the intensity of smoking. Nicotine and its derivative cotinine might be responsible for accelerating AGA progress pending further validation.

Cancer stem cells (CSC) are populations of cells responsible for tumor initiation, progression and therapeutic resistance in many cancers. In the present study, we aimed to investigate the expression pattern and clinical significance of the stem cell marker nestin, in Squaous cell carcinoma (SCC) and basal cell carcinoma (BCC). The samples (23 cases of BCC and 22 cases of SCC) were immunohistochemically examined for the expression of nestin and its correlation with the corresponding clinical and pathological parameters. Nestin was expressed in four out of the 23 cases of BCC (17.4%) and was expressed in 10 out of the 22 cases of SCC (45.5%). Nestin expression between the two tumors was statistically significant (P = .042). Although a direct relationship was found between the tumor grade and nestin expression, the results were statistically insignificant (P = .495). The results of this study suggest that BCC and SCC may share some cellular origin but with different biologic behavior. The relation of nestin expression to the grade of SCC, although statistically insignificant, may suggest its role in predicting the biologic behavior of this tumor.

The World Health Organization has recently defined the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections as a pandemic. The infection, which may cause a potentially very severe respiratory disease, now called coronavirus disease 2019 (COVID-19), has airborne transmission via droplets while less attention focused on aerosol transmission. Surgical smoke and plumes in laser clinics represent a source for aerosol particles. The aim of this article is to provide the authors' opinion for the correct use of "laser devices" in the COVID-19 emergency and to reduce potential risks of laser airborne contaminants.

BACKGROUND: Fractional CO2 laser is one of the most effective treatment options used to resurface scars. OBJECTIVE: To evaluate the efficacy and safety of early treatment of postsurgical scar by fractional ablative CO2 laser. METHODS: A total of 27 Egyptian patients with recent postoperative scars were enrolled in this study. Three sessions of fractional CO2 laser with a 1-month interval were started 4 weeks after surgery. Vancouver Scar Scale (VSS) was used as an assessment tool at 1 and 3 months after the final treatment. Patients reported their satisfaction using a subjective 4-point scale. RESULTS: Results demonstrated a statistically significant overall average improvement of the VSS (5.33±1.33) before compared with (2.55±1.06) 3 months after the last laser treatment (P≤0.001). Among the individual parameters in the VSS, the most significant improvements were found in pigmentation, height, and pliability. Patient's subjective satisfaction scores showed a significant greater degree of satisfaction after laser treatment. CONCLUSION: Fractional ablative CO2 laser is an effective and safe treatment modality for surgical scars in the early postsurgical period.
RESUMO
BACKGROUND: Warts, or verrucae, are benign epithelial profilerations of skin and mucosa caused by infection with HPV and poses a challenge to treat. OBJECTIVE: To compare between single and microneedling-assisted multipuncture techniques of intralesional application in treatment of plantar warts. METHODS: The study included 60 Patients who were divided into two groups (A&B). Each group consisted of (30) patients. Group (A) subjects received intralesional bleomycin with a single injection using syringe needle. For Group (B) subjects, we combined microneedling with topical spraying of bleomycin (MN + Bleo) and followed by occlusion for 2 hours. RESULTS: The results revealed complete clearance of warts in 21 patients in group (A) (70%) whom were treated by intralesional (IL) bleomycin vs 25 patients (83.3%) in group (B) whom were treated by spraying of bleomycin following microneedling. Side effects other than pain, erythema, and transient induration were relatively infrequent, and no nail changes or Raynaud's phenomenon was observed in both groups. CONCLUSION: We established a good safety and efficacy profile for bleomycin in plantar wart treatment and we demonstrated that microneedling followed by bleomycin spraying had a higher clearance and proved less painful as opposed to bleomycin injection.

BACKGROUND AND OBJECTIVE: Cutaneous leishmaniasis is a prevalent skin condition especially in the Middle Eastern region. The use of pulsed dye laser (PDL) for the treatment of cutaneous leishmaniasis (CL) has not been thoroughly evaluated. We assessed primarily the efficacy of 595-nm PDL in the treatment of CL lesions and interpreted its impact on the quality of life (QOL) of affected patients as measured by the Dermatology Life Quality Index (DLQI). PATIENTS AND METHODS: Twenty-five lesions from 12 patients were treated with a single pass of PDL over the whole lesions to develop a purpuric end point. Parameters used for this treatment were 7 J/cm2 fluence, 10-mm spot size, and 0.45-ms pulse duration. The laser settings were maintained in all subsequent treatments. RESULTS: Excellent response was noted in 13 of the 25 lesions after 3 sessions, while 12 of the remaining 25 lesions required 4 sessions toward complete recovery. The mean DLQI scores pre- and post-laser treatments were 12.67 and 4.25, respectively. All patients experienced a statistically significant improvement in their QOL (p < 0.05, paired t-test). CONCLUSION: The PDL is a new safe modality for treating cases of CL with further larger-scale studies could better determine its role.

BACKGROUND: Pruritus is a frequent symptom in the general population and in many skin and systemic diseases. Its frequency demonstrates a high burden and an impaired quality of life. AIM: Assessment of the efficacy of topically applied clove oil alone in the treatment of chronic pruritus. METHODS: Fifty selected subjects diagnosed with chronic pruritus due to either hepatic, renal, or diabetic causes were studied and divided into two groups of 25 patients each. Group I patients were instructed to hydrate the skin and then apply topical clove oil while group II patients applied petrolatum topically by hand; this application was done on the areas of pruritus, twice daily and for 2 weeks. The severity of the itch was assessed and compared before and after the study by 5-D itch scale. The results were analyzed by SPSS. Statistical methods such as descriptive analysis, independent-samples t-test, paired-samples t-test, and chi-square were employed. RESULTS: There was a significant improvement regarding all studied individual parameters (5-D itch scale) for the clove oil users with no significance among petrolatum users. Comparison of 5-D itch scale total score between patients of group I and patients of group II favored the improvement following the use of clove oil than using placebo (P value>.05). CONCLUSION: The topical treatment of chronic pruritus with clove oils is effective, easy to use, safe, cheap, and more acceptable for whom topical and systemic treatments tend to be irritating, contraindicated, or less well tolerated.

BACKGROUND: Pruritus is one of the commonest skin complaints. Peppermint oil can be effective in reducing the severity of such a condition. AIM: The aim of this study was to assess the efficacy of topically applied peppermint oil in the treatment of chronic pruritus. SUBJECTS AND METHODS: Fifty selected subjects diagnosed with chronic pruritus due to hepatic, renal, or diabetic cause were studied and divided into two groups of 25 patients each. Group I patients were instructed to hydrate the skin and then apply topical peppermint oil, while Group II patients applied petrolatum topically by hand; this application was done on the areas of pruritus, twice daily for 2 weeks. The severity of the itch was assessed and compared before and after the study by the 5-D itch scale (5D-IS). The results were analyzed by SPSS software. Statistical methods such as descriptive analysis, independent samples t-test, paired samples t-test, and chi-square test were employed. RESULTS: There was a significant improvement regarding all studied individual parameters (5-D IS) for the peppermint oil users with no significance among petrolatum users. A comparison of total score of 5-D IS between patients of Group I and patients of Group II favored the improvement following the use of peppermint oil than using placebo (P-value <0.05). CONCLUSION: The topical treatment of chronic pruritus with peppermint oil is effective, easy to use, safe, cheap, and more acceptable for those whose topical and systemic treatments tend to be irritating, contraindicated, or less well tolerated.
RESUMO
Striae distensae are common undesirable skin lesions of significant aesthetic concern. To compare the efficacy of two fluences (75 and 100 J/cm2) of long-pulsed Nd:YAG laser in the treatment of striae. Forty-five patients (Fitzpatrick skin types III-V) aged between 11 and 36 years with striae (23 patients with rubra type and 22 with alba type) were enrolled in the study. Each stria was divided into three equal sections, whereby the outer sections were treated with long-pulsed 1064 nm Nd:YAG laser, at a fluence of 75 or 100 J/cm2, and fixed laser settings of 5 mm spot size and 15 ms pulse duration. The middle section was an untreated control. All subjects received four treatments at 3 weeks interval. Three 2-mm punch biopsies were taken from six subjects, all of the same stria, one before treatment and the other two from the outer sections, 3 months after the last session. Paraffin-embedded skin sections were subjected to histological and quantitative morphometric studies for collagen and elastic fibres. Results were assessed clinically through photographic evaluation and were considered satisfactory for both doctors and patients. A significant improvement in appearance of striae alba using 100 J/cm2 was found while striae rubra improved more with 75 J/cm2. Histologically, collagen and elastin fibres increased in posttreatment samples. A satisfactory improvement in striae distensae lesions was seen through clinical and histological evaluation. Thus, long-pulsed Nd:YAG laser is a safe and effective module of laser treatment for these common skin lesions.
