ABSTRACT

BACKGROUND: Telemedicine involves distant exchange of medical information between health providers and patients via a telecommunication device with/without the aid of an audiovisual interactive assistance. The current COVID 19 pandemic impact on health services mandated an utmost readiness to implement telemedicine which in part is dependent on health care providers willingness to adopt such platforms. AIM: The aim of this cross sectional study was to assess knowledge and attitude toward telemedicine Egyptian dermatologists amidst the COVID 19 pandemic. PATIENTS AND METHODS: A cross sectional study was designed and data were collected using structured self-administered online questionnaires. RESULTS: Dermatologists had a good knowledge about telemedicine (mean 4.17 ± 1.63; p < .05). Of those completing the questionnaire, 193 (68.9%) were familiar with the term 'telemedicine' and 164 (58.6%) were familiar with tools like teleconferencing. The majority of responding dermatologists 227 (81.1%) were confident that the COVID 19 pandemic is a good opportunity to start applying telemedicine protocols however the majority 234 (83.6%) preferred using it on trial basis at first before full implementation. CONCLUSION: In conclusion an overall good attitude toward telemedicine was reported with a mean of 3.39 (p < .05). Further large scale studies are required to verify such findings.

ABSTRACT

BACKGROUND AND OBJECTIVES: The management of melasma is challenging and requires multiple uses of available therapeutic options. To compare the short-term efficacy and safety of topical silymarin and low fluence 1064-nm Q-switched ND:YAG laser for treatment of melasma with dermoscopic follow-up. STUDY DESIGN/MATERIALS AND METHODS: Fifty female patients with melasma were included in this study. They were randomly divided into two groups. Group A: 25 patients were treated with six sessions of low fluence Q switched ND:YAG 1064-nm laser, and group B: 25 patients were treated with topical silymarin cream 1.4% with a 3-month treatment duration. Patients were evaluated clinically by the modified melasma area and severity index (mMASI) score. Dermoscopic examinations were performed before and after the treatment sessions. RESULTS: The severity of melasma, as evaluated dermoscopically and clinically by mMASI score, was significantly reduced after treatment in all patients with no recorded side effects. There was no statistically significant difference between both studied groups regarding the change in mMASI score and dermoscopic assessment of the patients after the treatment sessions. CONCLUSION: Both low fluence Q switched ND:YAG 1064-nm laser and topical silymarin cream appear to be safe and effective modalities in the treatment of melasma. © 2021 Wiley Periodicals LLC.

ABSTRACT

BACKGROUND AND OBJECTIVES: Acne is a widespread disorder of the pilosebaceous unit. Isotretinoin is the background treatment of cases of severe acne. Side effects associated with the standard 0.5-1 mg/kg/day dose decrease patient compliance. Pulsed dye laser (PDL) was proved effective in the management of inflammatory acne. The focus was to evaluate the efficacy of combining low-dose isotretinoin (0.25 mg/kg/day) with PDL in comparison with the standard higher-dose isotretinoin (0.5 mg/kg/day) as monotherapy for the management of acne vulgaris. STUDY DESIGN/MATERIALS AND METHODS: The current prospective randomized comparative study included 46 acne patients, who were randomly divided into two groups. The first (ISO/PDL group) was treated with oral isotretinoin (0.25 mg/kg/day) and five sessions of PDL. The second (ISO group) was treated with oral isotretinoin (0.5 mg/kg/day). The physician's clinical assessment was done by three blinded dermatologists using quartile scale score and erythema score at baseline, 3 months, and 6 months and global acne grading system (GAGS) at baseline and 6 months. Patient satisfaction was assessed using the Cardiff Acne Disability Index (CADI). RESULTS: Both groups showed a significant improvement in all assessed parameters compared with baseline at 3 and 6 months. Comparing both groups together, the ISO/PDL group showed a statistically significantly greater improvement regarding all parameters at both assessment times. Regarding adverse events, six patients (26%) suffered from flare in the ISO group versus none in the combined group. Dryness was encountered in 20 patients (86%) in the ISO group versus five patients (21%) in the other group. The ISO/PDL group received significantly less cumulative isotretinoin dosage (48.7 ± 5.7 mg/kg) in comparison to the ISO group (100.4 ± 3.1 mg/kg) (P < 0.05). CONCLUSION: The current study offers a new collaboration between two well-studied and established treatment modalities leading to a harmony of therapeutic synergism while minimizing the risk of side effects. Longer periods of follow-up are recommended to diagnose any relapses and modify the proposed protocol. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

ABSTRACT

Warts are tumors or growths caused by infection with human papilloma virus (HPV). Currently, over 170 HPV types have been identified. This study aimed to evaluate the efficacy and safety of intralesional injection of methotrexate (MTX) for the treatment of plantar warts. Sixty patients presented with plantar warts were divided into two groups. Group A patients were injected with intralesional MTX (2 mg/ml). Group B patients were injected with intralesional saline as a placebo. The injections were repeated every week for a maximum of six sessions or until complete clearance, whichever was earlier. The patients were followed up for 6 months after the last injection. In the intralesional MTX group, 2 patients (6.7%) showed complete improvement, 8 patients (26.7%) showed partial improvement, and 20 patients (66.7%) showed no improvement. In the intralesional saline group, 3 patients (10%) showed complete improvement, 4 patients (13.3%) showed partial improvement, and 23 patients (76.7%) showed no improvement. Reported adverse events were local reactions in the form of swelling, pain, and infection in both groups. There was no statistically significant difference between the therapeutic responses to intralesional MTX injection and saline.

ABSTRACT

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.

ABSTRACT

Introduction: Non-ablative fractional erbium-doped glass 1540 nm and fractional ablative 10600 nm carbon dioxide lasers are regarded as effective modalities for treating acne atrophic scars. In this study, we aimed to compare the effectiveness of fractional CO2 laser and fractional nonablative 1540 nm erbium doped glass laser in treating post acne atrophic scars in Egyptian patients. Methods: Fifty-eight patients complaining of moderate and severe acne atrophic scars were randomly divided into 2 groups of 29 patients each. Both groups were subjected to 4 treatment sessions with 3 weeks interval and were followed up for 3 months. In group A, enrolled patient sreceived C2 laser, while in group B, patients were treated with 1540 nm erbium glass fractional laser. Results: Clinical assessment revealed that the mean grades of progress and improvement were higher with fractional 10600 nm CO2 laser but with non-significant difference between both treatments (P = 0.1). The overall patients' satisfaction with both lasers were not significantly different (P = 0.44). Conclusion: Both fractional ablative CO2 and fractional non-ablative erbium glass lasers are good modalities for treating acne scars with a high efficacy and safety profile and good patient satisfaction. The fractional ablative laser showed higher efficacy while non-ablative laser offered less pain and shorter downtime.

ABSTRACT

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.

ABSTRACT

In this work, nanovesicular chitosan gels were prepared for dermal delivery of terbinafine hydrochloride (TBN HCl). Ethosomes and vesicles containing different types of penetration enhancers (PEs) viz. Terpenes (cineole and limonene), labrasol and transcutol were developed. The prepared vesicles were evaluated for physical characteristics as well as skin interaction. The selected vesicles were incorporated into chitosan gel. An in vivo animal study was done on rat induced superficial Candida infection model. Moreover, randomized double blind clinical study was done on patients to compare the effect of the selected nanovesicular gel against the market product. Results showed the formation of nearly spherical, mostly deformable vesicular systems with size range of 95.5-530nm, zeta potential range of -0.1 to 15mV and entrapment efficiency range of 20-96.7%. Penetration enhancer vesicles (PEVs) prepared with 4% limonene (ELI4) showed the highest percent of drug deposition in the skin (53%) and the highest local accumulation efficiency value (35.3). In vivo animal study showed that the lowest fungal burden produced with ELI4 chitosan gel. Clinical studies showed cure rate of 86% within 7days treatment in case of limonene nanovesicular gel compared to 20% for market product (Lamisil® cream).

ABSTRACT

To evaluate the use of a pinpoint irradiation technique followed by nonablative fractional technique in treatment of traumatic scars. Thirteen patients with traumatic sacrs were treated with pinpoint technique of CO2 laser using traditional headpiece activating laser at a frequency (50 Hz) to deliver pulsed mode with power of 1 W using the focusing technique followed by 3-5 passes of the nonablative 1540 nm fractional Er:glass laser. An independent physician evaluator assessed the treatment outcomes using Vancouver scar scale (VSS) and 5-point grading scale (grade 0, no improvement; grade 1, 1-25%; grade 2, 26-50%; grade 3, 51-75%; grade 4, 76-100% improvement). After the final treatment, average percentage changes of VSS were 41.5%. Improvement was evident in terms of vascularity, pigmentation, and height, while insignificant in terms of Pliability. Based on physician's global assessment, mean grade of 2.5 was achieved. Patient's subjective satisfaction scores paralleled the physician's objective evaluation. Pinpoint irradiation technique by CO2 laser followed by nonablative fractional laser is a safe and effective modality in treatment of scars.

ABSTRACT

OBJECTIVE: To assess sperm chromatin integrity in infertile men with varicocele before and after surgical repair. DESIGN: Prospective. SETTING: Academic setting. PATIENT(S): Seventy-two infertile men with varicocele compared with 20 healthy fertile men. INTERVENTION(S): History taking, genital examination, semen analysis, sperm chromatin condensation assessment by aniline blue stain before and 3 months after varicocelectomy. MAIN OUTCOME MEASURE(S): Stained sperm heads (abnormal chromatin condensation) before and 3 months after varicocelectomy. RESULT(S): The mean percentage of aniline blue-stained sperm heads was significantly higher in infertile men with varicocele compared with fertile controls. The mean percentage of stained sperm heads was significantly decreased in infertile men with varicocele 3 months after surgery compared with the preoperative data. There was a significant negative correlation between percentage of stained sperm heads and normal morphology where nonsignificant correlation was elicited regarding sperm count and sperm motility. CONCLUSION(S): There is a significant increase of abnormal sperm chromatin condensation in infertile men with varicocele that is markedly improved after varicocelectomy.
