Q-switched Nd: YAG laser alone or with modified Jessner chemical peeling for treatment of mixed melasma in dark skin types: A comparative clinical, histopathological, and immunohistochemical study
Summary
Backgrounds
Treatment of mixed melasma remains challenging. Promising results have been achieved with low-fluence 1064-nm Q-switched Nd-YAG laser; however, multiple sessions are necessary with occurrence of complications especially in dark skin types. So, combination methods may be recommended.
Aims
To compare efficacy of Q-switched Nd-YAG laser alone or with modified Jessner's peel in mixed melasma in dark skin.
Patients/Methods
Nineteen patients with mixed melasma received 6 sessions of laser on left side of face and alternating laser and modified Jessner on right side. Evaluation was carried out clinically through modified melasma area and severity index at 1 month after last session. Using histopathological, immunohistochemical, and computerized morphometric analysis, objective evaluation of melanin particle surface area and MART-1-positive cells was performed for pre- and post-treated skin biopsies.
Results
There was significant clinical improvement on both sides of face (P < .001), without significant difference (P > .05). At the sixth laser session on left side of face, ill-defined mottled hypopigmentation was observed in 21.05% of patients. Histopathologically, melanin particle surface area and number of MART-1-positive cells (total, epidermal, and dermal) were significantly decreased after two treatment modalities (P < .001), without significant difference in their reduction percentage between both sides of face (P > .05).
Conclusion
Low-fluence Q-switched Nd-YAG laser alone and with modified Jessner's peel are equally effective regimens for mixed melasma clinically, histopathologically, and immunohistochemically. However, combined method is preferred, especially in dark skin, for obtaining better cosmetic result with fewer side effects of multiple laser sessions and decreasing cost rate of laser.

BackgroundHistological diagnosis of a clinically suspected nonmelanoma skin cancer (NMSC) is recommended before treatment. For NMSC, concordance between the histological subtype of the preoperative biopsy and the excision specimen of basal cell carcinoma (BCC) has been reported to range from 10% to 81%. No large study on the concordance between NMSC histology seen in a preoperative biopsy with the following tumour specimen from Mohs micrographic surgery (MMS) has been performed in a Latin American population.ObjectiveThe aim of this study was to analyse and compare the histological subtype of the incisional biopsies reviewed by the dermatopathologist with the histological subtype of the tumour specimen obtained during MMS interpreted by the dermatopathologist and the Mohs surgeon.MethodsA retrospective analysis of 320 NMSC was performed. The interobserver correlation was based on kappa values.ResultsThe mean weighted kappa value between the preoperative NMSC biopsy and intraoperative histological subtype of the tumour specimen from MMS analysed by the Mohs surgeon and the dermatopathologist was 0.22 and 0.24, respectively. The correlation in the histologic subtype of the intraoperative tumour specimen from MMS that was interpreted by the dermatopathologist and Mohs surgeon was 0.58.ConclusionsDermatologists need to be aware of the limited value of incisional biopsies to accurately diagnose the histological subtype of a NMSC. The concordance rate in the histological diagnosis of the tumour specimens that were obtained from MMS between the Mohs surgeon and the dermatopathologist is moderate. However, the correlation is low compared with incisional biopsy subtypes.

Inflammatory skin disorders and self-esteem
"I think you have ringworm. We can't accept a donation from you." The entire room went silent as everyone stared at Jennifer, age 34, who has suffered from severe plaque psoriasis since the age of 15 years and is now a patient advocate for the National Psoriasis Foundation (NPF). Jennifer was inspired to donate blood after her uncle received a lifesaving transfusion and hoped to help others like him, but she will likely never try again after this traumatizing experience. This was not the first time strangers had treated her as if she had a contagious skin infection.
Physiologic changes of pregnancy: A review of the literature
Throughout pregnancy, the body undergoes a variety of physiologic changes. The cutaneous findings can be most noticeable and often worrisome to both physicians and patients. Obstetricians and dermatologists must be able to differentiate between changes that are benign and those that may be pathologic. Most physicians recognize benign changes that are commonly described in literature such as hyperpigmentation, melasma, striae gravidarum, and telogen effluvium; however, they may be unaware of changes that tend to be less frequently discussed.
Radiation-induced circumscribed superficial morphea after brachytherapy for endometrial adenocarcinoma
Radiation-induced morphea (RIM) is a rare and underrecognized complication of radiation therapy that most commonly occurs in women after treatment for breast cancer. Although not fully understood, RIM is hypothesized to arise from an increase in cytokines that stimulate collagen production and extracellular matrix formation. Most documented cases of RIM occur 1 year after radiation therapy and are localized to areas that were treated for breast cancer. We report on a case of a female patient with stage IB endometrial adenocarcinoma who was treated with 24 Gray of adjuvant brachytherapy.
