RESUMO
Abstract The frequency of the use of drugs that act on the epidermal growth factor receptor (EGFR) is increasing, with the consequent onset of cutaneous toxicity, specifically acneiform eruption. The authors extensively review the topic, focusing on describing how these drugs can affect the skin and its appendages, that is, the pathophysiology that encompasses the cutaneous toxicity related to the use of EGFR inhibitors. In addition, it was possible to list the risk factors that may be associated with adverse effects of these drugs. Based on this recent knowledge, the authors expect to aid in the management of patients who are more vulnerable to toxicity, reduce morbidities, and improve the quality of life of patients undergoing treatment with EGFR inhibitors. Other issues related to the toxicity of EGFR inhibitors, such as the clinical aspects of the acneiform eruption grades, and other different types of cutaneous and mucosal reactions, are also included in the article.
RESUMO
BACKGROUND: In cutaneous melanomas in general, tumor inflammatory infiltrate (TII) can protect against distant metastases, but there is no consensus when only thin primary cutaneous melanomas (TPCM) are considered. OBJECTIVE: To investigate the presence of TII in TPCM and the relationship between TII and the occurrence of metastases. METHODS: Case-control study including 50 patients with TPCM, 22 metastatic (MC group) and 28 non-metastatic (NMC group). The presence of TII was evaluated and, if present, qualified as mild, moderate or marked. RESULTS: The mean age was 50.7 years in the MC and 56.2 years in the NMC group (pâ¯=â¯0.234), and the male sex predominated in the MC group (63.6%). The average Breslow thickness was higher in the MC when compared to that observed in the NMC (respectively 0.8 vs. 0.6â¯mm, pâ¯=â¯0.012). The presence of ulceration occurred in 22.7% of the MC and 17.9% of the NMC (pâ¯=â¯0.732). TII was present in all 50 TPCM, being marked or moderate in 67.9% of the NMC and 54.5% in the MC group (pâ¯=â¯0.503). In the multivariate analysis, the presence of moderate and marked TII had an Odds Ratio (OR) of 0.57 (95% Confidence Interval [CI]: 0.18â1.8) and adjusted OR of 0.68 (95% CI 0.13â3.99). STUDY LIMITATIONS: Small sample size. CONCLUSIONS: TII was present in all TPCM (with and without metastases), and it was not possible to demonstrate a protective effect of TII against the appearance of metastases.

Increasing research has been conducted on the role of probiotics in disease treatment. Kefir, a safe, low-cost probiotic fermented milk drink, has been investigated in many in vitro and animal studies, although parameters for human therapeutic dose or treatment time have not yet been determined. Here we perform a scoping review of clinical studies that have used kefir as a therapeutic agent, compiling the results for perspectives to support and direct further research. This review was based on Joanna Briggs Institute guidelines, including studies on the effects of kefir-fermented milk in humans. Using the term KEFIR, the main international databases were searched for studies published in English, Spanish or Portuguese until 9 March 2022. A total of 5835 articles were identified in the four databases, with forty-four eligible for analysis. The research areas were classified as metabolic syndrome and type 2 diabetes, gastrointestinal health/disorders, maternal/child health and paediatrics, dentistry, oncology, women's and geriatric health, and dermatology. The many study limitations hampered generalisation of the results. The small sample sizes, methodological variation and differences in kefir types, dosage and treatment duration prevented clear conclusions about its benefits for specific diseases. We suggest using a standard therapeutic dose of traditionally prepared kefir in millilitres according to body weight, making routine consumption more feasible. The studies showed that kefir is safe for people without serious illnesses.

Abstract Background In hospital settings, dermatology can offer substantial clinical support for the diagnosis and management of skin conditions, reducing morbidity and mortality. Thus, the study aimed to analyze the profile of referrals and consultations performed by the Dermatology Service of the Santa Casa de Misericordia de Porto Alegre, from August 2018 to January 2020. Methods This study is descriptive, quantitative, and retrospective, conducted through data collection and review of medical records and referrals. The variables included were clinical data of referrals, in-patients profiles, dermatological diagnoses, complementary exams, therapeutic conduct, and recommended follow-ups. Results A total of 1020 referrals were analyzed, which resulted in 641 consultations (328 men, 313 women). The most prevalent skin disease groups were 'Dermatitis and Eczema' (33.1%) and 'Other infectious skin diseases (21.8%), while the most frequent ICD-10 were 'Drug eruptions - L27' (9.9%) and 'Other and unspecified dermatitis - L30' (6.6%). Corticoids were the most recommended treatments (27.7%), followed by antifungals (13.1%). 'Consultation Discharge' (44%) and 'Outpatient' Dermatology follow-up (27%) were the most frequent causes for ending consultation. Study limitations Among the study limitations, the authors highlight its retrospective nature, with data analysis based on referrals and medical records, which may present inaccurate or incomplete information. In addition to this, the study may demonstrate a certain degree of subjectivity due to the review and interpretation process conducted by the researchers. However, the definition of objective criteria based on previous studies attenuates such possible bias. Furthermore, considering that the Dermatology teams are composed of a preceptor dermatologist and residents, the established diagnoses were not submitted to third-party verification, except in the cases of skin biopsies and cultures. Thus, the professional's experience and skills may have influenced the dermatological diagnoses. Conclusions These findings underlie the importance of Dermatology in hospital assistance, contributing to the management of a wide range of skin conditions.
RESUMO
Abstract This publication is an update of the "Consensus on the therapeutic management of atopic dermatitis - Brazilian Society of Dermatology" published in 2019, considering the novel, targeted-oriented systemic therapies for atopic dermatitis. The initial recommendations of the current consensus for systemic treatment of patients with atopic dermatitis were based on a recent review of scientific published data and a consensus was reached after voting. The Brazilian Society of Dermatology invited 31 experts from all regions of Brazil and 2 international experts on atopic dermatitis who fully contributed to the process. The methods included an e-Delphi study to avoid bias, a literature search and a final consensus meeting. The authors added novel approved drugs in Brazil and the indication for phototherapy and systemic therapy for AD. The therapeutical response to systemic treatment is hereby reported in a suitable form for clinical practice and is also part of this updated manuscript.
