Abstract
In high-risk basal cell carcinomas (BCCs), micrographic surgery (MS) has high tissue preservation and low recurrence rates. The Mohs technique is the most commonly used technique, with limited use of other MS techniques. No studies have been designed to compare the MS methods. This review aimed to assess BCC recurrence rates of different MS techniques. A systematic review and meta-analysis was conducted to search for related studies in PubMed, LILACS, EMBASE, SCOPUS, WEB OF SCIENCE, CINHAL, and COCHRANE until March 2021. Randomized clinical trials (RCTs) and observational studies involving patients with BCC and indications for different MS techniques were included. Study selection and data extraction were performed independently by three peer reviewers, as was the risk of bias assessment using the Joanna Briggs Institute tool. Pooled estimates were assessed using the random-effects model (Logit), and heterogeneity was assessed by the chi-square test (χ2 ). Stata Software version 17.0 was used for analysis. Eighteen studies were included, 2 RCTs and 16 observational studies. The overall recurrence rate was 2% (95% CI, 1.0-3.0%; χ2 = 46.2; p = 0.00; 18 studies, 10,424 BCCs). In studies using the Mohs technique, the recurrence rate was 3.0% (95% CI, 1.0-5.0%; χ2 = 11.0; p = 0.00; 6 studies; 1,582 BCCs), with the Munich technique 3.0% (95% CI, 2.0-5.0%; χ2 = 0.0; no heterogeneity; 3 studies; 404 BCCs), with Tubingen technique 1% (95% CI, 1.0-2.0%; χ2 = 12.1; p = 0.00; 8 studies; 8,374 BCCs) and with the Muffin technique 0.0% (95% CI, 0.0-6.0%; 1 study; 64 BCCs). Relapse rates between MS techniques were low and appeared to be similar. However, the design of this review and the absence of primary studies that directly compare the techniques do not allow us to assert the superiority between them.

Abstract
BACKGROUND Melasma can be refractory to treatment, and relapses are frequent. Thiamidol is a new potent tyrosinase inhibitor that has been found effective as a cosmeceutical for the depigmenting of melasma. OBJECTIVE This study compared the efficacy and tolerability of topical 0.2% Thiamidol vs. 4% hydroquinone for facial melasma. METHODS Fifty women with facial melasma participated in a randomized, evaluator-blinded, controlled study from September through November 2020. Patients were randomly assigned to apply a double layer of 0.2% Thiamidol twice a day or 4% hydroquinone cream at bedtime, for 90 days. Both groups received tinted sunscreen (sun protection factor 60, PPD 20). The primary outcome was the change from the baseline Modified Melasma Area Seve:rity Index (mMASI) score. Secondary outcomes were improvements in the patients' quality of life [Melasma Quality of Life Index (MELASQoL)], colourimetry, and Global Aesthetic Improvement Scale (GAIS) evaluation. RESULTS One participant, from the hydroquinone group, did not complete the study (unrelated to adverse effects). The mean (SD) age of the participants was 43 (6) years, and 86% were phototypes III-IV. Both groups exhibited a reduction in mMASI, MELASQoL, and colour contrast scores (P < 0.01). The mean [95% confidence interval (CI 95%)] reductions of the mMASI scores were 43% (35-50%) for Thiamidol and 33% (23-42%) for hydroquinone. There was no difference between the groups in the reductions in mMASI, MELASQoL, colourimetric contrast and GAIS scores (P ≥ 0.09). The GAIS analysis resulted in an improvement of 84% (CI: 95% 67-97%) for participants in the Thiamidol group and 74% (CI: 95% 61-93%) for those in the hydroquinone group. There were only mild adverse effects in the Thiamidol group, but allergic contact dermatitis was evidenced in two (8%) participants. CONCLUSION The melasma improvement achieved using 0.2% Thiamidol did not differ from that of 4% hydroquinone cream. Thiamidol can be considered a suitable option for melasma patients with poor tolerability or treatment failure with hydroquinone.

Abstract
Cryptorchidism (CPT), the most common male congenital abnormality, is variably associated with other male reproductive tract problems. We evaluated if cryptorchid rats develop enhanced testicular susceptibility to dibutyl phthalate (DBP) or acrylamide (AA) after extended exposure. Three studies with rats were performed: (1) in utero and postnatal exposure to DBP or AA; (2) establishment of CPT and orchiopexy; and (3) in utero and postnatal exposures to DBP or AA associated with CPT/orchiopexy. Seminiferous tubules were histologically scored according to the severity of lesions: (1) Rats exposed to DBP (score 1.5) or AA (score 1.1) presented mostly preserved spermatogenesis. Some seminiferous tubules showed vacuolated germinative epithelium, germ cell apoptosis, and a Sertoli cell-only (SCO) pattern. (2) CPT (score 3.3) resulted in decreased absolute testes weights, degenerated and SCO tubules, and spermatogenesis arrest that were reversed by orchiopexy (score 1.1). (3) Exposure to DBP or AA with CPT/orchiopexy led to atrophic testes, spermatogenesis arrest, germ cell exfoliation/multinucleation, and SCO tubules (both chemicals score 2.5). Exposure to chemicals such as DBP or AA prevented the recovery of cryptorchid testes by orchiopexy. The possible role of environmental contaminants should be considered when looking for factors that modulate human testicular disorders associated with CPT.

Abstract
BACKGROUND The physiopathology of epidermal hypermelanization in melasma is not completely understood. Several cytokines and growth factors are increased in skin with melasma, nevertheless, nor the pathways involved in the increased αMSH expression have been adequately evaluated, nor a model for sustained focal melanogenesis is available. OBJECTIVE To explore stimulatory pathways for epidermal pigmentation in facial melasma related to αMSH: those linked to ultraviolet radiation, oxidative stress, inflammation, neural crest pigmentation cell differentiation and antagonism of αMSH. METHODS Paired skin biopsies (3 mm) from 26 women with facial melasma and from normal adjacent skin (<2 cm far) were processed for immunofluorescence with markers for p53, p38, αMSH, MC1R, Melan-A, IL-1α, COX2, Wnt1, WIF-1 and ASIP. RESULTS The fluorescence intensity in the skin from melasma was higher for MC1R, αMSH at epidermis as at melanocytes (P < 0.05). There were no differences between the sites in epidermal protein expression of COX2, IL-1α, p53, WIF-1 and ASIP (P > 0.1). P53 was expressed only in epidermis, without difference between sites (P = 0.92). WNT1 was remarkable in the epidermis of melasma (P < 0.01), but not in dermis. Positive p38 cells were prominent in the upper dermis of melasma (P < 0.01), despite no marking in epidermis. CONCLUSION Melanogenesis in melasma involves epithelial secretion of αMSH and activation of the Wnt pathway; nevertheless, it seems to be independent of the stimulation by ultraviolet radiation/p53, IL-1α, COX2/PgE2 , WIF-1 and ASIP. Damaged cells at upper dermis suggest the role of senescence/autophagy in sustained pigmentation in melasma.

Abstract
BACKGROUND Melasma is a common chronic focal hypermelanosis that affects photexposed areas as face, mainly in women at fertile age. It inflicts a significant impact in quality of life; nevertheless, quality of life scores (e.g. MELASQoL) are not strongly correlated with clinical severity (e.g. MASI) in facial melasma, suggesting that different factors can influence the perception of disease beyond the clinical extension or the intensity of pigmentation. OBJECTIVES To explore clinical and socio-demographic aspects that influences MELASQoL scores. METHODS Cross-sectional study enrolling 155 adults (>18 y.o.) with facial melasma. MELASQoL, MASI, clinical and demographic information were assessed. The associations among factors were explored by multivariable methods. RESULTS The mean (SD) age of the participants was 39 (8) years, and 134 (86%) were females. The correlation (Spearman's rho) between MELASQoL and MASI was 0.35 (P < 0.05). In a multivariate regression, MELASQoL score was associated (P ≤ 0.05) to MASI score (β = 0.6), lower income (β = 6.8), be single (β = 4.2) and low education level (β = 5.0). At multiple correspondence analysis, MASI, sex, marriage, education and income were associated with MELASQoL, as well as MASI was associated to skin phototypes, income and education level. CONCLUSION The perception of life quality impairment in melasma is influenced by low scholarly, low family income, single marital status and greater clinical severity.

Abstract
OBJECTIVE Compare gene and protein expression for oestrogen receptor-β (ER-β) and progesterone receptor (PR) in facial melasma and adjacent healthy skin. METHODS A cross-sectional study including 42 women with facial melasma, conducted at the Dermatology Service of Botucatu Medical School of São Paulo State University, Brazil. Biopsies of the melasma skin were performed, together with healthy surrounding skin. The gene expression (real-time PCR) of the hormone receptors in the tissue was evaluated. Subsequently, skin fragments were immunostained for nuclear ER-β and PR, evaluated according to their HSCORE (epidermis) and percentage of staining per microscopic field (dermis). RESULTS Messenger RNA tissue expression for ER-β and PR showed no difference between melasma-affected skin fragments and the healthy perilesional areas (P > 0.2). Median nuclear epithelial expression for ER-β and PR was higher in lesioned skin (HSCORE 157 and 58) than in the healthy perilesional skin (HSCORE 97 and 19; P < 0.01), with no difference in dermal immunostaining. Nuclear histological expression for ER-β was associated to sun-induced melasma and negative familiar background; PR expression was associated to sun-induced melasma and darker phototypes. CONCLUSION No difference was observed in gene expression for oestrogen-β and progesterone receptors in melasma-affected skin compared with adjacent healthy skin. However, the higher protein expression of these receptors in melasma-affected epithelia suggests hormonal participation in the pathogenesis of this disease.

Abstract
BACKGROUND The aim of this study was to evaluate the symptoms of dry mouth and salivary flow in menarche and menopausal women. METHODS Objective and subjective assessment of salivary function were analysed by Xerostomia Inventory and Visual Analogue Scale questionnaire in menopausal and menarche women (control group). Salivary flow was evaluated by a chemical absorption stimulation test. Each subject provided three saliva samples: S1, non-stimulated saliva; S2, saliva initially stimulated with two drops of citric acid 2.5%; and S3, saliva super-stimulated with two drops of citric acid 2.5% every 30 seconds for two minutes. RESULTS No intergroup association was observed between Xerostomia Inventory and Visual Analogue Scale questionnaire. In both groups, the salivary flow was greatest at S3, followed by S2 and finally S1. Salivary flow was lower in the menopausal group compared to the control group only in S2 and S3. CONCLUSIONS In the menopausal group, the salivary flow showed reduction but without clinical symptoms of dry mouth. It is important to normalize salivary flow to prevent oral abnormalities and maintain oral health.

Abstract
BACKGROUND The pathogenesis of melasma and the role of keratinocytes in disease development and maintenance are not completely understood. Dermal abnormalities, the expression of inflammatory mediators, growth factors, epithelial expression of melanocortin and sexual hormones receptors suggest that not only melanocytes, but entire epidermal melanin unit is involved in melasma physiopathology. OBJECTIVES To compare nuclear morphological features and chromatin texture between basal keratinocytes in facial melasma and adjacent normal skin. METHODS We took facial skin biopsies (2 mm melasma and adjacent normal skin) from women processed for haematoxylin and eosin. Thirty non-overlapping basal keratinocyte nuclei were segmented and descriptors of area, highest diameter, perimeter, circularity, pixel intensity, profilometric index (Ra) and fractal dimension were extracted using ImageJ software. RESULTS Basal keratinocyte nuclei from facial melasma epidermis displayed larger size, irregular shape, hyperpigmentation and chromatin heterogeneity by fractal dimension than perilesional skin. CONCLUSION Basal keratinocytes from facial melasma display changes in nuclear form and chromatin texture, suggesting that the phenotype differences between melasma and adjacent facial skin can result from complete epidermal melanin unit alterations, not just hypertrophic melanocytes.

Abstract
BACKGROUND Corrective eyeglasses are frequently worn by adults, particularly at older ages. Their lenses and frames provide ultraviolet protection. Medial canthal basal cell carcinomas are infrequent (3-8%), and their relation with the use of corrective glasses was not yet investigated. OBJECTIVES To assess the prevalence of corrective eyeglasses use in individuals with medial canthal basal cell carcinoma. METHODS Case-control study using two controls matched by age, gender, and ethnicity for each case. Cases were patients with medial canthal basal cell carcinoma, and controls were patients with basal cell carcinoma elsewhere on the face. The prevalence of major risk variables was estimated and adjusted by conditional multiple logistic regression. RESULTS Fifty cases and 100 controls were assessed. The mean patient age was 69.7 years, and 54% of the subjects were females. No difference regarding the eyeglasses use or use duration was found between groups. However, when visual defects were separately evaluated, eyeglasses for myopia correction were independently associated with lower risk of medial canthal basal cell carcinoma development (OR=0.26; P=0.03), what can be related to long term local photoprotection. CONCLUSION The use of eyeglasses for myopia correction is associated with lower prevalence of medial cantal basal cell carcinoma. Risk-reducing mechanisms should be elucidated.

Abstract
BACKGROUND Palmoplantar pustulosis (PPP) discloses some differences compared to vulgar psoriasis (PV) in terms of age of onset, female predominance and low occurrence of psoriasis lesions elsewhere. Cigarette smoking has been associated to PPP in international studies; nevertheless, these studies were never performed among Brazilian. OBJECTIVES To compare prevalence of smoking among PPP, PV and other dermatologic patients (NPD). METHODS Case-control study involving 25 PPP patients from a reference psoriasis centre. Two control groups were matched according to gender and age: 50 patients with PV and 50 NPD. Confounders were adjusted by conditional multiple logistic regression. RESULTS Among cases, 84.0% were female and PPP age of disease onset (41.4 years) was greater than PV (34.5 years). Prevalence of ever smoking was higher among cases (92.0%) than PV (52.0%) and NPD (30.0%). Adjusted odds ratio of PPP ever smoking compared to PV and NPD was 9.5 and 36.2, respectively. All smokers reported the onset of their habit before the development of PPP. CONCLUSIONS There was significant association between PPP and smoking. However, the impact of giving it up in the clinical course of the disease remains to be established.

Abstract
We established a Website which allowed clinical dermatology cases to be submitted, with digital images, through a simple online form. The case could then be managed within the public health service. A database containing 6000 drug interactions was also available on the Website to help clinical management. The Website was tested by 10 junior doctors, who examined dermatology patients, filled in the electronic form with their clinical observations and descriptions, and forwarded digital images. Five dermatologists then evaluated the 71 cases stored on the Website. The agreement between the virtual evaluation and the definitive diagnosis (on face-to-face examination) was 95%. The Website could be used in national health strategies, as a tool for promoting voluntary medical attendance, and for multicentre epidemiological surveillance.

Abstract
Localized lymphatic sporotrichosis generally develops after the fungus Sporothrix schenckii is traumatically introduced into skin or mucosa by contaminated plant material. An 18-year-old male fisherman was injured by spines of the dorsal fin of a fish on the left third finger. The lesion became ulcerated, edematous and suppurative and did not respond to tetracycline and cephalexin. Fifteen days after the accident, a nodular lymphangitic pattern of swelling was observed. Histopathological findings and an intradermal test were suggestive of sporotrichosis and mycological cultures confirmed the diagnosis. The lesions resolved after oral treatment with potassium iodide. Sporotrichosis is a common subcutaneous mycosis in Brazil, and there is a previous report in the literature of this disease being acquired via trauma involving fish spines.
