RESUMO
Objectives The aim of this study was to ascertain whether pattern of cutaneous lesions, age, sex, ethnicity, long-term medication use, arterial oxygen saturation at the first examination, setting of care, and number of medications used to treat SARS-CoV-2 infection are associated with mortality in patients with a confirmed diagnosis of coronavirus disease 2019 (COVID-19) and cutaneous manifestations. In addition, to evaluate the occurrence of cutaneous manifestations in patients with a confirmed diagnosis of COVID-19 through a review of medical records and in-person evaluation by a dermatologist. Methods This investigation consisted of two components - (A) a cross-sectional study with a retrospective review of the medical records of all patients with a positive reverse-transcriptase polymerase chain reaction (RT-PCR) test for SARS-CoV-2 treated at Santa Casa de Misericórdia de Porto Alegre between March 2020 and November 2020, and (B) a prospective case series with in-person skin examination by an attending dermatologist of all patients admitted to COVID-19 wards between April 2021 and July 2021. The pattern of skin lesions and other variables were assessed. Results Information from 2968 individuals with COVID-19 was collected (2826 from the medical records and 142 from the in-person examination by a dermatologist). Of these, a total of 51 patients (1.71%) had COVID-19-related cutaneous lesions - 36 from the medical records group (1.27% of cutaneous manifestations) and 15 from the examinated group (10.56% of cutaneous manifestations). Of 51 patients, 15 (29.41%) died. There was no association between mortality and patterns of cutaneous manifestations. The variables male sex (p=0.021), intensive care unit (ICU) admission (p=0.001), and use of three or more antibiotics (p=0.041) were associated with higher mortality. Conclusions The risk factors, proven by our study, for mortality in patients with COVID-19 and cutaneous manifestations were male sex, ICU stays, and use of three or more antibiotics. Using the review of medical records as a tool for evaluating cutaneous manifestations related to COVID-19, there are about 10 times fewer occurrences when compared to in-person evaluation by a dermatologist.
RESUMO
BACKGROUND: In March 2020, social isolation measures were imposed in Brazil to contain the spread of the novel coronavirus (SARS-CoV-2), requiring health services to implement contingency plans. The main objective of the study was to verify the status of the disease, self-reported by patients who discontinued phototherapy, during a period of social isolation. METHODS: All patients receiving phototherapy at the Santa Casa de Porto Alegre, Brazil, prior to the implementation of social distancing measures were eligible for inclusion in the study. 86 patients answered a questionnaire during a medical evaluation. RESULTS: 95% of patients who stopped phototherapy reported a worsening of disease status. Only 19% of patients continued to attend phototherapy sessions during the social isolation period. CONCLUSION: The COVID-19 pandemic led most patients to stop phototherapy, resulting in the perception of increased disease severity in an outpatient sample in southern Brazil.

RESUMO Objetivo: Analisar o perfil clínico de pacientes em acompanhamento dermatológico encaminhados para avaliação oftalmológica. Métodos: A amostra foi composta de pacientes dermatológicos encaminhados para avaliação oftalmológica, nos anos de 2016 e de 2017. Estudou-se a concomitância de doenças dermatológicas com as afecções oftalmológicas por meio da coleta simultânea do histórico dermatológico (prontuários registrados com dados gerais e diagnóstico) e de dados da consulta oftalmológica após o encaminhamento. Resultados: Foram avaliados pela oftalmologia 224 pacientes, sendo 65% do sexo feminino, 80% caucasianos, com idade variando entre 1 mês e 85 anos. As situações cujo encaminhamento foi mais prevalente foram psoríase, lúpus, vitiligo e rosácea (18,3%, 13,8%, 12,9% e 10,7%, respectivamente). Fototerapia crônica e uso de hidroxicloroquina representaram 35,7% e 22,3% dos pacientes. Casos de neurofibromatose, micose fungoide, líquen plano, neoplasias de pele, atopias, pênfigo e esclerodermia também estiveram presentes. Cegueira legal foi detectada em 6%, e deficiências visuais ligadas a afecções dermatológicas foram verificadas em 16,5% dos casos. As alterações oculares mais prevalentes foram catarata (18,9%), blefarite (15,9%), pterígio (5,3%) e conjuntivite (5,3%). Conclusão: Encontrou-se elevada frequência de alterações oftalmológicas em uma população de pacientes com doenças dermatológicas. Assim, o estudo e a análise de manifestações oculares em pacientes dermatológicos podem auxiliar na detecção precoce e na prevenção de complicações.
ABSTRACT Objective: To analyze the clinical profile of patients under dermatological care and referred to ophthalmological evaluation. Methods: The sample comprised dermatology patients referred to ophthalmological evaluation in 2016 and 2017. The simultaneous occurrence of skin and ophthalmic diseases was studied, by collecting dermatological history (medical records containing general data and diagnosis) and ophthalmic consultation data following referral. Results: A total of 224 patients were assessed, 65% were female, 80% were white, and age varied between one month and 85 years. The conditions more often referred were psoriasis, lupus, vitiligo and rosacea (18.3%, 13.8%, 12.9% and 10.7%, respectively). Chronic phototherapy and use of hydroxychloroquine were observed in 35.7% and 22.3% of patients, respectively. Cases of neurofibromatosis, mycosis fungoides, lichen planus, skin cancer, atopic dermatitis, pemphigus and scleroderma were also reported. Legal blindness was detected in 6% and visual impairment related to skin conditions in 16.5% of patients. The most prevalent ocular changes were cataracts (18.9%), blepharitis (15.9%), pterygium (5.3%) and conjunctivitis (5.3%). Conclusion: A high frequency of ophthalmic changes in a population of dermatological patients was found. In this context, studying and analyzing ocular manifestations in dermatological patients could be useful in early detection and prevention of complications.

We report a case of phaeohyphomycosis that affected the leg of a 45-year-old Brazilian man, car mechanic and renal transplanted. The direct mycological examination evidenced dematiaceous septated hyphae. The pathogenic fungal species was identified as Exophiala xenobiotica. Antifungal activity in vitro revealed terbinafine as the best antifungal. For treatment, it was chosen surgical excision of the entire lesion and used systemic itraconazole. Phaeohyphomycosis caused by Exophiala xenobiotica is extremely rare and is closely related to transplant patients.
RESUMO
BACKGROUND: Ophthalmic findings in mycosis fungoides (MF) can be highly variable. It seems that the prevalence of ophthalmic findings could be much more common than previously assumed. OBJECTIVE: To present case series examined in the last 12 months, together with a literature review. METHODS: Symptomatic patients with biopsy-proven mycosis fungoides were examined ophthalmologically in a 12-month period. The medical records of affected patients were reviewed. RESULTS: Eight patients were examined. Of these, 75% were male, all were Caucasian, and average age was 58.2 years. Blepharitis (50.0%), thickened eyelids (37.5%), and flaking (25.0%) were the most prevalent findings. CONCLUSION: Incidence of MF affecting the eyes and surrounding structures may be greater than estimated. Early case management offers means to reduce difficulties experienced with later diagnosis. Regular monitoring by an ophthalmologist is justified, including that of asymptomatic cases.
RESUMO
Halitose é uma condição comum relacionada com fatores sistêmicos e orais que afeta diferentes grupos de idade. O objetivo deste estudo foi avaliar a prevalência de halitose autorreferida e fatores associados. Indivíduos que se apresentaram para o alistamento em Pelotas foram designados a comparecer no 9º Batalhão de Infantaria motorizado, em dia e hora previamente agendados. Na ocasião, os indivíduos responderam a um questionário com questões sobre saúde oral e geral que fazia parte de um consórcio envolvendo avaliação dermatológica e antropométrica. Dentre os avaliados, 2274 recrutas responderam ao questionário, dos quais 10,1% relataram apresentar halitose. Os indivíduos foram alertados sobre sua halitose por alguém de seu convívio próximo ou esporádico. As variáveis mais frequentemente mencionadas foram fumo, seguido de higiene oral pobre, associadas ao aumento da prevalência de halitose em 61% (PR=1.61; 95% CI: 1.18-2.20) e, aproximadamente 2.5% (PR=246; 95% CI: 1.26 4.83), respectivamente. A escolaridade também mostrou relação com halitose (p<0.001). Um total de 20,1% da amostra tentou mascarar seu mau hálito de alguma forma e 12% relatou algum tipo de preocupação com seu hálito. Concluiu-se que a halitose é uma condição comum na população estudada, estando associada ao fumo, higiene oral pobre e baixo grau de instrução. Indivíduos com halitose normalmente relatam desconforto associado com essa condição oral.
Halitosis is a common condition related to oral or systemic factors that affect different age groups. The study aimed to evaluate the prevalence of self-reported halitosis as well as associated factors to this condition. Subjects joining the Army in Pelotas were asked to be at the 9th Infantry Battalion on the day and time previously scheduled. On the occasion, the subjects answered a questionnaire containing questions on oral and general health. The questionnaire was completed by 2274 recruits and 10.1% of the subjects reported to have suffered from halitosis. They were told about it by someone living with them or by close persons who were part of their daily routine. The most often mentioned variables were related to smoking, which increased the prevalence of halitosis in 61% (PR=1.61; 95% CI: 1.18-2.20), followed by poor oral conditions which increased halitosis approximately 2.5 times (PR=2.46; 95% CI: 1. 26 4.83). Educational level was also associated with halitosis (p<0.001). A total of 20.1% from the sample tried to mask their bad breath in some way and 12% expressed some kind of concern related to it. It was concluded that halitosis is a common condition in evaluated population. It was found to be associated with smoking, poor oral health care and low education level. People with halitosis usually report some kind of discomfort caused by this oral condition.

BACKGROUND: Prevalence of acne varies worldwide. Several factors (age, skin color, body fat, diet, and smoking) have been investigated as risk factors. OBJECTIVE: A total of 2,201 18-year-old males living in Pelotas, South Brazil, were evaluated in order to examine the prevalence of acne and associated factors. METHODS: A cross-sectional population-based study was conducted. A dermatologist performed the clinical examination of the face and trunk for identification of acne lesions. Acne was evaluated as clinically noninflammatory, inflammatory, and acne with both types of lesions. Skin color, schooling, height, smoking, skinfolds, waist circumference, BMI, and dietary dairy intake were the independent variables used. RESULTS: A response rate of 97.2% was obtained. Individuals without any acne lesion were 241 (10.9%); 161 (7.3%) only had noninflammatory lesions, 404 (18.4%) only inflammatory lesions; and 1,395 (63.4%) presented both types of lesions. In multivariate analysis, the type of lesions was different in light and dark skin phototype adolescents, with more common inflammatory lesions in the light phototype and noninflammatory ones in the dark phototype patients. Height was directly associated with the occurrence of all types of acne, whereas lower fat mass was associated with the occurrence of noninflammatory acne. While daily consumption of whole milk or yogurt was found to be associated with inflammatory acne in crude analysis, the association with milk was not detected and that with yogurt was low in multivariate analysis. CONCLUSION: Our results suggest that future studies should explore determinants of noninflammatory and inflammatory acne separately, especially if mixed populations are studied.

BACKGROUND: Psoriasis is an immune-mediated inflammatory disease for which treatment has evolved over the past few years due to the introduction of immunobiologic and small molecule inhibitor medications. A better understanding of the comparative efficacies of drugs may help doctors to choose the most appropriate treatment for patients. OBJECTIVE: The aim of this study was to conduct a systematic review and meta-analysis to assess the efficacy of immunobiologic and small molecule inhibitor drugs for patients with moderate to severe psoriasis. DATA SOURCES: The EMBASE, PUBMED, LILACS, Web of Science and ClinicalTrials.org databases were searched for trials published to 21 July 2016. STUDY SELECTION: Only randomized, double-blind, placebo-controlled clinical trials that evaluated the efficacy of immunobiologics or small molecule inhibitors for moderate to severe plaque-type psoriasis were selected by two independent authors. No restrictions were used. DATA EXTRACTION AND SYNTHESIS: Two authors independently extracted the data and a random-effects model meta-analysis was performed. MAIN OUTCOMES AND MEASURES: The Psoriasis Area and Severity Index (PASI) 75 was considered the primary outcome, measured at the primary endpoint of each study. RESULTS: Thirty-eight studies were included in our analysis. The overall pooled effect favored biologics and small molecule inhibitors over placebo (risk difference [RD] 0.59, 95% confidence interval [CI] 0.58-0.60). Ixekizumab at a dose of 160 mg on week 0 and then every 2 weeks (RD 0.84, 95% CI 0.81-0.88), brodalumab 210 mg (RD 0.79, 95% CI 0.76-0.82), infliximab 5 mg/kg (RD 0.76, 95% CI 0.73-0.79), and secukinumab 300 mg (RD 0.76, 95% CI 0.71-0.81) showed a greater chance of response (PASI 75) when compared with placebo. LIMITATIONS: The methodology of a traditional meta-analysis does not allow for drugs to be ranked. Included studies used short-term endpoints (10-16 weeks) to evaluate the primary outcome, therefore long-term efficacy could not be determined. CONCLUSIONS AND RELEVANCE: The anti-IL-17 drugs brodalumab, ixekizumab and secukinumab showed an equal or greater chance of helping patients achieve a 75% improvement on PASI compared with other reviewed drugs.

BACKGROUND: Acne vulgaris is a pilosebaceous follicle disorder affecting over 85% of adolescents to some degree. It frequently causes psychological distress that may persist into adulthood due to scarring. Little information about post-acne scarring epidemiology is available. OBJECTIVES: To describe prevalence, distribution patterns and associated factors of acne scarring in young males, drawing on a representative population sample from a southern Brazilian city. METHODS: A cross-sectional study was undertaken during presentation for military service, which is compulsory for all 18-year-old males. A questionnaire was applied, covering topics like diet, smoking habits, ethnicity, family structure, socio-economic level, as well as specific questions about active acne and resulting scars. Dermatologists conducted the clinical examination. RESULTS: A total of 2,201 male adolescents were interviewed and examined. The overall prevalence of acne scarring was 22%. The malar region was the most frequently involved, present in 80% of affected individuals, followed by the frontal region (31.5%), back (17%), anterior chest (8.2%) and mentonian region (6.4%). Correlation between the intensity of clinical acne and the presence of scars was found, but no association was observed with educational level, smoking, ethnicity, obesity or socio-economic status. CONCLUSIONS: There is a high prevalence of acne scars among this population. This is the first study to ascertain a correlation between acne scarring and factors such as socio-economic status and educational level. The direct relation between acne severity and scarring indicates that prompt and effective treatment is the best way to reduce scarring.
