Casos e óbitos por COVID-19 e tabagismo nas capitais e regiões brasileiras: estudo ecológico / COVID-19 cases and deaths and smoking in Brazilian capitals and regions: an ecological study / Casos y muertes por COVID-19 y tabaquismo en las capitales y regiones Brasileñas: estudio ecológico

Objetivo: Analisar a relação entre casos e óbitos por COVID-19 e o percentual de tabagistas nas capitais e regiões do Brasil. Métodos: Realizou-se estudo ecológico nas regiões brasileiras do número de casos e óbitos por COVID-19, de março a dezembro de 2020, e a prevalência de tabagismo em 2019, a partir dos bancos de dados do Painel Coronavírus da Secretaria de Vigilância em Saúde e do Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL ­ 2019). Com informações extraídas em janeiro de 2021, calcularam-se os coeficientes de incidência e mortalidade por COVID-19 por capital brasileira e região, bem como se utilizou a correlação de Pearson para verificar a relação entre as variáveis do estudo. Adotou-se nível de significância de 5%. Resultados: Análises bivariadas mostraram correlações positivas entre tabagistas do sexo feminino e coeficiente de incidência de COVID-19 nas capitais da região do Centro-Oeste (r=0,957; p=0,043), e entre fumantes do sexo masculino e coeficiente de mortalidade de COVID-19 nas capitais do Nordeste (r=0,706; p=0,034). Conclusão: O tabagismo teve impacto na incidência de casos e óbitos por COVID-19 em diversas capitais brasileiras, alertando que o fumo pode ser fator de predisposição e agravamento do estado clínico dos pacientes.

Objective: To analyze the relationship between COVID-19 cases and deaths and the percentage of smokers in the capitals and regions of Brazil. Methods: An ecological study was carried out in the Brazilian regions to assess the number of cases and deaths by COVID-19 from March to December 2020 and the prevalence of smoking in 2019 based on the Coronavirus Panel databases of the Health Surveillance Secretariat and the System for Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone-based Survey (Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico - VIGITEL ­ 2019). With information extracted in January 2021, the COVID-19 incidence and mortality coefficients were calculated by Brazilian capital and region and Pearson's correlation was used to verify the relationship between the study variables. A significance level of 5% was adopted. Results: Bivariate analyses showed positive correlations between female smokers and COVID-19 incidence coefficient in capitals of the Midwest region (r=0.957; p=0.043), and between male smokers and COVID-19 mortality coefficient in the capitals of the Northeast (r=0.706; p=0.034). Conclusion: Smoking had an impact on the incidence of COVID-19 cases and deaths in several Brazilian capitals, which warns that smoking can be a predisposing factor and worsen the clinical status of patients.

Conclusión: El tabaquismo tuvo impacto en la incidencia de casos y muertes por COVID-19 en diversas capitales brasileñas, advirtiendo que el humo puede ser factor de predisposición y agravamiento del estado clínico de los pacientes.

Molecular profile of non-small cell lung cancer in northeastern Brazil.

OBJECTIVE: To investigate the histological subtypes and mutational profiles of non-small cell lung cancer in Brazil, looking for correlations among histological subtypes, expression of anaplastic lymphoma kinase (ALK), EGFR mutation status, and programmed death-ligand 1 (PD-L1) expression. METHODS: We evaluated 173 specimens obtained from patients with lung adenocarcinoma in northeastern Brazil. Expression of PD-L1 and ALK was evaluated by immunohistochemistry; EGFR mutation status was evaluated by sequencing. We categorized the histological subtypes in accordance with the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification. RESULTS: The most common histological subtypes of lung adenocarcinoma were solid predominant (in 46.8%), acinar predominant (in 37.0%), and lepidic predominant (in 9.8%). ALK expression was detected in 10.4% of the samples, and 22.0% of the tumors harbored EGFR mutations. The most common EGFR mutation was an exon 21 L858R point mutation (in 45.5%), followed by an exon 19 deletion (in 36.3%). The tumor proportion score for PD-L1 expression was ≥ 50% in 18.2% of the samples, 1-49% in 32.7%, and 0% in 49.5%. The solid predominant subtype was significantly associated with wild-type EGFR status (p = 0.047). Positivity for PD-L1 expression was not found to be significantly associated with ALK expression or EGFR mutation status. CONCLUSIONS: Our results suggest that the molecular profile of non-small cell lung cancer in northeastern Brazil differs from those of populations in other regions of the country, with ALK positivity being higher than the other biomarkers. Further studies including clinical and genetic information are required to confirm these differences, as well as studies focusing on populations living in different areas of the country.

RESUMO Objetivo: Investigar os subtipos histológicos e perfis de mutação do carcinoma pulmonar de células não pequenas no Brasil, bem como as correlações entre os subtipos histológicos, a expressão do gene anaplastic lymphoma kinase (ALK, quinase do linfoma anaplásico), o estado de mutação do gene EGFR e a expressão de programmed death-ligand 1 (PD-L1, ligante de morte celular programada 1). Métodos: Avaliamos 173 espécimes provenientes de pacientes com adenocarcinoma pulmonar no Nordeste brasileiro. A expressão de PD-L1 e ALK foi avaliada por meio de imuno-histoquímica, ao passo que o estado de mutação do EGFR foi avaliado por meio de sequenciamento. Os subtipos histológicos foram classificados de acordo com a International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society. Resultados: Os subtipos histológicos mais comuns de adenocarcinoma pulmonar foram o predominantemente sólido (em 46,8%), o predominantemente acinar (em 37,0%) e o predominantemente lepídico (em 9,8%). A expressão de ALK foi detectada em 10,4% das amostras, e 22,0% dos tumores apresentavam mutações do gene EGFR. As mutações mais comuns do EGFR foram a mutação pontual L858R no éxon 21 (em 45,5%) e a deleção do éxon 19 (em 36,3%). O tumor proportion score relativo à expressão de PD-L1 foi ≥ 50% em 18,2% das amostras, = 1-49% em 32,7% e = 0% em 49,5%. O subtipo predominantemente sólido relacionou-se significativamente com EGFR selvagem (p = 0,047). A expressão positiva de PD-L1 não se relacionou significativamente com a expressão de ALK ou o estado de mutação do EGFR. Conclusões: Nossos resultados sugerem que o perfil molecular do carcinoma pulmonar de células não pequenas no Nordeste brasileiro difere do de populações em outras regiões do país: a expressão positiva de ALK é maior que os demais biomarcadores. Mais estudos com informações clínicas e genéticas são necessários para confirmar essas diferenças, além de estudos que se concentrem em populações em diferentes áreas do país.

Kyrle's disease associated with HIV infection, diabetes, and chronic kidney disease.

Kyrle's disease (KD) is a rare skin pathology characterized by transepidermal elimination of abnormal keratin. The aim of this article is to report a rare case of KD associated with diabetes mellitus, chronic kidney disease, and HIV. A 51-year-old male patient complained of diarrhea for 8 months. He was submitted to HIV testing, which showed a positive result. He started antiretroviral therapy with zidovudine, lamivudine, and lopinavir. The diagnostic investigation was negative for opportunistic diseases. After 2 months, skin lesions started appearing, characterized by hyperchromic, pruritic macules and papules distributed in the trunk, back, and upper limbs. He also developed erythematous, scaly lesions in the facial region. A biopsy of the skin was performed, of which histopathological report consisted of perforating disorder, favoring a diagnosis of KD. Treatment with keratolytic soap (Actine) was started, with skin lesion improvement. In this reported case, it is possible that, in addition to diabetes and renal failure, HIV infection played an important role in the genesis of the lesions.

Invasive head and neck cutaneous squamous cell carcinoma: clinical and histopathological characteristics, frequency of local recurrence and metastasis.

BACKGROUND: squamous cell carcinoma is the second most common type of skin malignancy and may evolve to regional lymph node and distant metastases. OBJECTIVE: The objective of this study was to evaluate patients with head and neck cutaneous squamous cell carcinoma to identify its clinical and histopathological characteristics, as well as the frequency of local recurrence and metastasis. METHODS: A retrospective cohort of patients with head and neck cutaneous squamous cell carcinoma. INCLUSION CRITERIA: histopathological confirmation, follow-up for longer than one year after diagnosis. EXCLUSION CRITERIA: immunosuppression; lip and oral cavity squamous cell carcinoma; and non-surgical resection of the lesion. We evaluated demographic, clinical and anatomopathologic findings and explored their associations. RESULTS: Sixty-one patients with 79 tumors and followed by 4.8±3.0 years were selected. The average age was 67.1 years, and 63% of tumors had up to two centimeters. Seven tumors (8.9%) recurred and two of them had positive margins. Recurrence was associated with higher Broders' grade (p<0.01). Two patients (3.3%) had regional lymph node metastases. There were no distant metastases. Seventy tumors were considered to be usual tumors (89.7%), and 68 (87.2%) were classified as Broders' grade 1 and 2. Additionally, 64.1% of tumors had a depth of invasion below four millimeters. Thirteen tumors (16.7%) had positive histological margins. CONCLUSIONS: Most patients had good prognosis in the first year of follow-up, confirming that head and neck cutaneous squamous cell carcinoma has a better prognosis than squamous cell carcinoma of other regions such as mucosa, oral cavity, and internal organs.

Avaliação das características histopatológicas e imuno-histoquímicas do fronte de invasão tumoral do carcinoma espinocelular cutâneo de cabeça e pescoço e sua importância no comportamento biológico / Evaluation of histopathology and immunohistochemical characteristics of tumor invasion of forehead of cutaneous squamous cell carcinoma of the head and neck and its importance in biological behavior

O carcinoma espinocelular (CEC) é tumor maligno das células espinhosas da epiderme caracterizado por evolução mais rápida, maior poder invasivo e metastático em relação ao carcinoma basocelular (CBC). A área mais profunda e infiltrativa do CEC, conhecida como fronte de invasão, revela células neoplásicas malignas com menor grau de diferenciação comparadas à totalidade da lesão. Estudos recentes demonstram a influência do padrão do fronte de invasão tumoral no prognóstico de CEC de laringe e colo uterino. Contudo, não há estudos sobre o mesmo em relação a CEC cutâneos de cabeça e pescoço. Estudar as características clínicas, histopatológicas e perfil imuno-histoquímico do CEC de cabeça e pescoço e fronte de invasão tumoral, correlacionando-o com comportamento biológico. O estudo foi do tipo coorte retrospectivo, sendo selecionados os pacientes que tiveram diagnóstico de CEC de cabeça e pescoço confirmados pelo exame anatomopatológico no período de 1999 a 2009. A avaliação do fronte de invasão tumoral foi realizada empregando-se imuno-histoquímica para E-caderina, ki-67 e p53. Resultados: O tipo de fronte de invasão, bem como as expressões de E-caderina e ki-67, seja em sítio superficial ou profundo, não apresentaram associação com os critérios prognósticos histopatológicos. Os achados mostraram que a E-caderina, o p53 e o ki-67 foram mais expressos em tumores com tamanho ˃ 2cm. Em relação a espessura do tumor, observamos que o p53 foi mais expresso na profundidade nas lesões mais espessas (índice de Breslow maior que 2mm), e que foi acompanhada também pela expressão maior do Ki-67.A expressão de p53 em sítio superficial teve associação inversa com o critério de espessura (p<0,049) e, em sítio profundo, teve associação direta com a intensidade do processo inflamatório local (p<0,046)...

The Squamous Cell Carcinoma (SCC) is a malignant epidermal tumor of squamous epithelial cells, characterized for greater aggressiveness much higher incidence of metastasis than Basal Cell Carcinoma (BCC). The deepest invading tumor area, known as invasive tumor front usually disclose less differentiated malignant cells, compared with the whole lesion. Recent studies demonstrate the influence of the invasive tumor front pattern on the prognosis of larynx and uterine cervix SCC. However, there is no studies about that on cutaneuos SCC of the head and neck. To study the clinical, histopathological and immunohistochemical profile of the SCC from head and neck and its invasive tumor front, correlating it with its biological behavior. The study was a retrospective type coorte, where the patients with histopathological diagnosis of head and neck cutaneous SCC among 1999 to 2009 were selected. The evaluation of invasive tumor front was immunohistochemistry for E-cadherin, ki-67 and p53. The pattern of invasive tumor front, as well as E-cadherin and ki-67 expressions, at superficial and deep sites, did not present association with histopathological prognostic criteria. The findings showed that E-cadherin, p53 and Ki-67 were more highly expressed in tumors with size ˃ 2cm. Regarding the thickness of the tumor, we observed that p53 was expressed in depth in thicker lesions (Breslow thickness greater than 2 mm), which was also accompanied by higher expression of Ki-67. p53 expression, at superficial site, had inverse association with thickness criteria (p<0,049) and, at deep site, had direct association with local inflammatory process intensity (p<0,046). The invasive tumor front, as well as E-cadherin, ki-67 and p53 expressions, at superficial and deep sites, did not demonstrate impact on free disease survival...

Pediatric chronic sclerosing sialadenitis: Küttner tumor.

Chronic sclerosing sialadenitis is an uncommon cause of salivary gland enlargement mainly occurring in the fifth and seventh decade of life. In the Western population, chronic sclerosing sialadenitis has been characterized as an IgG4-related disease. Although rare, this lesion occurs in children. To increase awareness about this entity in the pediatric age group, we report the case of an 11-year-old boy with a hard, 4.0-cm circumscribed mass in the right submandibular gland. Histologically there was marked distortion of the gland architecture by a dense lymphocytic infiltrate and extensive fibrosis with septa that crossed and distorted the gland, leaving atrophic acini and dilated, irregular ducts. The lymphoid infiltrate formed multiple follicles with active germinal centers, numerous plasma cells, and areas with diffuse arrangement. Immunophenotyping showed abundant CD20- and CD3-positive lymphocytes; cytokeratin AE1/AE3 highlighted the distorted architectural pattern; IgG staining showed large numbers of positive cells infiltrating the interstitium and surrounding the atrophic acini and ducts. IgG4 staining revealed a large proportion of positive infiltrating elements. Küttner tumor belongs to the group of IgG4-related sclerosing diseases. The differential diagnosis includes pleomorphic adenoma and other salivary gland neoplasms. Its recognition in children is important clinically because this entity is amenable to steroid treatment, and additional work up and follow up is warranted to stave off other IgG4-related diseases/complications.
