However, in visceral leishmaniasis (VL), the efficiency of antimonials deteriorates in immunocompromised patients [15] accentuating the essential role of immune competency. In the same context, SbV was found to be dependent on the

There are several types of medical settings which use lasers. Dermatologists use lasers as it is non-invasive with preferential cosmetic outcomes and finer wound healing. The types of lasers are relying on their wavelengths and delivery systems.Over time, by using several distinct devices and strategies, new lasers have been generated; as a consequence, they are manipulated in a wide range of dermatological settings. In this review, laser applications in various vascular, infectious, and hyperpigmented cutaneous lesions were framed. We aimed to represent the fitness of phototherapy for each condition as well as the overall challenges that face laser. In addition, low-level laser therapy, and laser resurfacing were noted as the marketable line of lasers in the current time for cosmetic purposes.

Background: Some basal cell carcinoma (BCC) patients are considered as a high risk regarding the site, size, histopathological variant, or recurrence. High-risk BCC is a challenging therapeutic problem due to the trial to balance between complete surgical excision from one side and tissue preservation from the other side.Aim: To evaluate the efficacy of combining ablative CO 2 laser, imiquimod 5%, and diclofenac 3% as a therapeutic regimen in high-risk and inoperable BCC.Patients/Methods: The study was conducted on 14 patients that were assessed clinically and pathologically then categorized regarding the site, size, histopathology, and fitness for surgery as high-risk inoperable BCC. They received an ablative session of CO 2 laser, followed by application of diclofenac sodium 3% gel once daily for 5 days and imiquimod 5% cream for another 2 days. Results:The study included 11 males and 3 females. Nine lesions were located on the scalp, 4 on the face, and one lesion on the trunk. All lesions were of large size >5 cm in diameter. Histopathology showed 4 patterns: nodular type in 8 patients, infiltrating type in 3 patients, metatypical type in 2 patients, and micronodular type in one patient. At the end of the treatment period, 9 patients showed significant (moderate to marked) improvement while 5 patients showed weak (poor to mild) response.Significant improvement was more observed in nodular type. Relapse was more observed during the 5 th to 6th months with 2 patients showed no relapse. Conclusion:This combined regimen is a good alternative therapeutic modality in highrisk inoperable BCC especially the nodular pathologic pattern.

Purpose Basal cell carcinoma (BCC) is the most diagnosed type of cancer accounting for 80% of all keratinocyte malignancies. However, the exact demographic properties and clinicopathological criteria for BCC in Egyptians are not clearly reported. Our aim is to report and analyze the epidemiological and clinicopathological features of BCC in Egyptians. Methods We retrospectively reviewed the medical records for patients diagnosed pathologically with BCC during the period from January 2017 to December 2021. Data were recruited from four dermatology centers with different geographical distributions. Results We registered 544 patients. Their age ranged between 22–91 years with a mean of 61.6 ± 13.2 years. Females showed younger age of onset. The mean duration of the tumor was 3.9 ± 3.8 years. The most common involved region was the head (79.4%), and about one third of patients (32.2%) had a giant lesion (> 5 cm). The most common clinical presentation was ulcerative lesions (44.9%). Pathologically, the nodular type represented the most common variant (50.4%). Conclusion Our results proposed that the annual incidence of BCC is increasing among Egyptians. Ultraviolet radiation is considered a high-risk factor of BCC leading to a higher affection of the head region and more prevalence in men. This study also highlights some criteria of BCC in Egyptians such as the long duration of the tumor, the early onset in females, the higher percentage of giant types, and the predominance of nodular type. To our knowledge, this is the first report describing the characteristic features of BCC among Egyptians.
