Oral manifestations and injuries related to covid- 19: an experience report on the role of hospital dentistry / Manifestações orais e lesões relacionadas à covid-19: um relatório de experiência sobre o papel da odontologia hospitalar / Manifestaciones orales y lesiones relacionadas con covid- 19: un informe de experiencia sobre el papel de la odontología hospitalaria

SARS-COV-2 is transmitted among human beings by saliva droplets that come in direct contact with the oral cavity, nose, and eyes. Since the mouth is one of the anatomical sites primarily contaminated, oral manifestations have also been reported beyond the serious consequences inherent to progressive respiratory failure. This study aimed to identify oral manifestations possibly related to the infection by COVID-19 in hospitalized patients. A prospective study was carried out with patients diagnosed with COVID-19 in the period between March and June 2021, admitted to the Moderate COVID-19 Care Unit of the Hans Dieter Schmidt Regional Hospital, by applying a form and performing a clinical exam of the oral cavity. Out of all patients (n=45), 33.3% reported both olfactory (anosmia) and taste dysfunction (dysgeusia), with an average duration of 5.9 ±3.0 days. Regarding other oral manifestations evaluated, two patients reported dry and burning mouth and one patient reported a change in taste associated with plaque-like changes in the tongue. No patients presented ulcers or other lesions in the oral cavity. Olfactory and taste dysfunction were symptoms recognized of the novel coronavirus disease (COVID-19). However, the association with other oral manifestations is still controversy. Unfortunately, dentistry professionals are still not part of most teams in the hospital environment, mostly because of the lack of prioritization of dental care. Working with a multidisciplinary team may avoid possible systemic complications due to poor dental care.

Sars-COV-2 é transmitida entre os seres humanos por gotículas de saliva que entram em contato direto com a cavidade oral, nariz e olhos. Uma vez que a boca é um dos sítios anatômicos principalmente contaminados, as manifestações orais também foram relatadas para além das graves consequências inerentes à insuficiência respiratória progressiva. Este estudo teve como objetivo identificar manifestações orais possivelmente relacionadas à infecção por Covid-19 em pacientes hospitalizados. Foi realizado um estudo prospetivo com pacientes diagnosticados com Covid-19 no período entre março e junho de 2021, internados na Unidade de Atendimento Moderado contra a Covid-19 do Hospital Regional Hans Dieter Schmidt, aplicando um formulário e realizando um exame clínico da cavidade oral. De todos os pacientes (n=45), 33,3% relataram disfunção olfativa (anosmia) e gustativa (disgeusia), com duração média de 5,9 ±3,0 dias. Em relação a outras manifestações orais avaliadas, dois pacientes relataram boca seca e ardente e um paciente relatou alteração no paladar associada a alterações semelhantes a placas na língua. Nenhum paciente apresentou úlceras ou outras lesões na cavidade oral. Disfunção olfativa e gustativa foram sintomas reconhecidos do novo coronavírus (Covid-19). No entanto, a associação com outras manifestações orais ainda é controversa. Infelizmente, os profissionais de odontologia ainda não fazem parte da maioria das equipes do ambiente hospitalar, principalmente por causa da falta de priorização dos cuidados odontológicos. Trabalhar com uma equipe multidisciplinar pode evitar possíveis complicações sistêmicas devido a cuidados odontológicos deficientes.

Differences in the diagnosis of primary cutaneous melanoma in the public and private healthcare systems in Joinville, Santa Catarina State, Brazil

Abstract: Background: Cutaneous melanoma accounts for up to 80% of deaths caused by skin cancer. Diagnostic suspicion and access to medical care and early intervention in suspected cases is vital to the patient's prognosis. Objectives: To compare demographic and histopathological characteristics of primary cutaneous melanoma diagnosed in the public healthcare system (Sistema Único de Saúde SUS) and the private system in Joinville, Santa Catarina State, Brazil. Methods: This cross-sectional retrospective study analyzed primary cutaneous melanoma cases recorded from 2003 to 2014 in the resident population of Joinville. Ethical approval was obtained from the local Research Ethics Committee. Results: 893 cases of primary cutaneous melanoma were identified. Patients in the private system were mostly younger, while there were more elderly patients in the public healthcare system (p <0.001). There was no statistically significant association between type of care (public/private) and gender or presence of multiple primary cutaneous melanomas. Histological diagnosis of superficial spreading melanoma was more common in patients treated in private healthcare, while nodular melanoma was more frequent in patients in the public healthcare system (p <0.001). Mean Breslow depth in patients treated in private healthcare was 1.35mm, compared to 2.72mm in the public system (p <0.001). Study limitations: This was a retrospective study using secondary databases. Conclusions: thin cutaneous melanoma (in situ cutaneous melanoma and Breslow T1) showed the strongest association with the private healthcare system, while thick cutaneous melanoma was more frequent in the public system (Breslow category T3 and T4) (p <0.001).

Epidemiological and histopathological aspects of primary cutaneous melanoma in residents of Joinville, 2003-2014

Abstract: Background: The worldwide incidence of cutaneous melanoma (CM) has been continuously increasing over the last decades. Primary and secondary prevention, with attention to risk factors and early diagnosis, remain the cornerstone for reducing the burden of cutaneous melanoma. Detailed information with respect to clinical and pathological data on cutaneous melanoma is scarce in Brazil. Objective: The purpose of our study was to analyze epidemiological and pathological characteristics of primary cutaneous melanoma in Joinville, southern Brazil. Methods: Observational, cross-sectional, retrospective study in which 893 reports of primary cutaneous melanoma from the local population were analyzed in the period 2003-2014. The study was approved by the local Ethics and Research Committee. Results: We observed a female predominance of cutaneous melanoma (56.3%). The age standardized incidence rate of primary cutaneous melanoma for the world population in the period 2003-06 was 11.8 per 100,000 population (CI 95%, 10.3-13.4), and 17.5 (CI 95%, 15.7-19.3) in 2011-14, revealing a significant increase of 48.3% (p < 0,05). Six and a half percent of patients had multiple cutaneous melanomas (mean 2.2 years and a maximum of 10.0 years between diagnoses). We observed significant differences between the location head/neck and cutaneous melanoma in situ, lower limb with Breslow depth S III and upper limb with Breslow depth S I. The comparison of the characteristics of cutaneous melanoma in the elderly and non-elderly (< 60 years old) showed significant differences with respect to all the variables studied. Study limitations: Using secondary data source. Conclusion: Joinville has high incidence coefficients for Brazilian standards, showing an increase in the incidence of cutaneous melanoma.

Importância clínica e correlação histológica das células glandulares atípicas detectadas no exame colpocitológico / Clinical implications and histological correlation of atypical glandular cells found in cervicovaginal smears

Introduction: Atypical glandular cells (AGC) are carriers of insufficient nuclear abnormalities for the diagnosis of adenocarcinoma, but exceed the criteria for classification as reactive glandular cells. This is an uncommon diagnosis, which may be associated with neoplastic lesions. Objective: To evaluate the clinical significance of primary cytological diagnosis of AGC through correlation with results of subsequent cyto-histologic examination. Materials and methods: 10 years retrospective study based on cervical cytologic results indicating AGC, classified as "possibly non-neoplastic" or "cannot exclude high-grade intraepithelial lesion". It was performed cyto-histopathological correlation in cases that were submitted to subsequent histopathological examination up to two years after cervical cytology analysis. Results: AGC were reported in 380 (0.06%) exams, providing 160 cases with subsequent biopsy. 85 (53.1%) of these, presented benign changes and 75 (46.9%) neoplastic lesions. From 114 "possibly non-neoplastic" cytological results, 71 (62.3%) had benign histological changes, and 43 (37.7%) neoplastic lesions, corresponding to a negative predictive value (NPV) of 62.3%. In contrast, among the 46 AGC "cannot exclude high-grade intraepithelial lesion" results, 14 (30.4%) presented benign changes and 32 (69.6%) neoplastic lesions (positive predictive value [PPV] = 69.6%). Discussion: The high rate of cancer associated with the diagnosis of AGC reassures the importance of recognizing these atypical cells in pap smears. The classification of "possibly non-neoplastic" and "cannot exclude high-grade intraepithelial lesion" may suggest the origin of cytological changes. Conclusion: Our results reinforce the importance of adequate follow-up of patients with AGC diagnosis on cervical cytology...

Introdução: Células glandulares atípicas (CGA) são portadoras de alterações nucleares insuficientes para o diagnóstico de adenocarcinoma, mas excedem os critérios para classificação como células glandulares reacionais. Trata-se de um diagnóstico incomum, porém pode relacionar-se com lesões neoplásicas. Objetivo: Avaliar o significado clínico do diagnóstico citológico primário indicando CGA por meio da correlação com os resultados de exames histológicos subsequentes. Materiais e métodos: Estudo retrospectivo de 10 anos com base em resultados colpocitológicos indicando CGA, classificados como "possivelmente não neoplásicas" ou "não se pode afastar lesão intraepitelial de alto grau". Realizou-se a correlação cito-histopatológica nos casos que foram submetidos ao exame histopatológico até dois anos após a análise colpocitológica. Resultados: CGA foram relatadas em 380 (0,06%) exames, dispondo-se de 160 casos com biópsia subsequente. Destes, 85 (53,1%) apresentavam alterações benignas e 75 (46,9%), lesões neoplásicas. Dos 114 resultados citológicos "possivelmente não neoplásicas", 71 (62,3%) apresentavam alterações histológicas benignas e 43 (37,7%), neoplásicas, correspondendo a um valor preditivo negativo (VPN) equivalente a 62,3%. Contrariamente, entre os 46 resultados de CGA "não se pode afastar lesão intraepitelial de alto grau", 14 (30,4%) apresentavam alterações benignas e 32 (69,6%), neoplásicas (valor preditivo positivo [VPP] = 69,6%). Discussão: As altas taxas de neoplasias associadas ao diagnóstico de CGA reafirmam a importância do reconhecimento dessas atipias. A classificação em "possivelmente não neoplásicas" e "não se pode afastar lesão intrapitelial de alto grau" pode sugerir a origem das alterações citológicas. Conclusão: nossos resultados reforçam a importância do segmento das pacientes com diagnóstico de CGA no exame colpocitológico...

Dirofilariose humana em Joinville-SC: avaliação clinicopatológica dos primeiros casos relatados na região Sul / Human dirofilariasis in Joinville-SC: clinical-pathological assessment of the first cases reported in the Southern region

INTRODUÇÃO: Dirofilariose é uma zoonose rara causada pelo gênero Dirofilaria e acomete principalmente os pulmões, sendo capaz de simular neoplasia pulmonar. Pouca informação está disponível na literatura sobre a ocorrência e a distribuição de dirofilariose humana na América do Sul. Até 2004, haviam sido descritos apenas 50 casos de dirofilariose humana pulmonar no Brasil, sendo 37 apenas em São Paulo. OBJETIVO: Comprovar a existência de dirofilariose na região de Joinville-SC. MATERIAIS E MÉTODOS: Revisão de arquivos de laboratórios de anatomia patológica da cidade à procura de casos com os termos granuloma parasitário, helminto, helmintíase, verme, Dirofilaria e dirofilariose. Foram incluídos na pesquisa casos que satisfizeram os critérios para dirofilariose, segundo literatura específica. Os prontuários foram revisados e as amostras reprocessadas e analisadas histologicamente por seis colorações diferentes. RESULTADOS: Encontrou-se um caso em globo ocular e sete casos pulmonares, sendo o lobo inferior a localização preferencial (cinco casos). A análise microscópica revelou, nos casos pulmonares, nódulo bem delimitado, frequentemente centrado em uma artéria, com reação granulomatosa e necrose associada à fibrose e infiltrado inflamatório mono e polimorfonuclear, sendo possível identificar segmentos do parasita degenerado, compatível com Dirofilaria immitis. DISCUSSÃO: Todos os parasitas encontrados apresentam características morfológicas idênticas às relatadas na literatura para Dirofilaria immitis. A presença de D. immitis no globo ocular, como observada em um dos pacientes na presente revisão, é rara. CONCLUSÃO: A ocorrência de dirofilariose humana foi confirmada em Joinville e região, sendo causada pela Dirofilaria immitis.

INTRODUCTION: Dirofilariasis is a rare zoonosis caused by Dirofilaria genus, which affects mainly the lungs and may be misdiagnosed as lung cancer. Little information is available regarding the occurrence and distribution of human dirofilariasis in South America. Only 50 cases of human pulmonary dirofilariasis were described in Brazil until 2004, of which 37 were located in São Paulo. OBJECTIVE: To prove the existence of dirofilariasis in Joinville, SC. MATERIAL AND METHODS: The records of anatomic pathology laboratories of the city were reviewed in search for cases with the terms parasitic granuloma, helminth, helminthiasis, worm, Dirofilaria and dirofilariasis. According to specific literature, the cases that met the criteria for dirofilariasis were included in the study. The medical records were reviewed and the samples reprocessed and histologically analyzed by six different stains. RESULTS: We found one ocular case and seven pulmonary cases. The lower lobe was the main location (five cases). In all pulmonary cases, microscopic analysis revealed well defined nodules, frequently centered in a pulmonary artery, with granulomatous reaction and necrosis associated with fibrosis and mono and polymorphonuclear inflammatory infiltrate. It was also possible to identify segments of the deteriorated worm consistent with Dirofilaria immitis. DISCUSSION: All parasites found in this study show morphological characteristics similar to those reported in the literature on Dirofilaria immitis. The presence of D. immitis in the eye, as reported in one of the patients from this review, is rare. CONCLUSION: The occurrence of human dirofilariasis was confirmed in Joinville and region and it was caused by Dirofilaria immitis.
