RESUMO

Abstract Objective: To investigate the prognostic factors to developing parotid and neck metastasis in locally advanced and relapsed Cutaneous Squamous Cell Carcinoma (CSCC) of the head and neck region. Methods: Single-center retrospective cohort study enrolling consecutive patients with advanced CSCC from 2009 to 2019. Seventy-four cases were identified. Study variables demographic data, clinical skin tumor stage, neck stage, parotid stage (P stage), surgical treatment features, and parotid, regional, and distant metastases. Survival measures: Overall Survival (OS) and Disease-Specific Survival (DSS). Results: The study group included 72.9% men (median age, 67 years); 67.5% showed T2/T3 tumors, 90.5% comorbidities, 20.2% immunosuppressed, with median follow-up: 35.8 months. The most frequent skin primary were auricular and eyelid regions, 75% underwent primary resection with flap reconstruction. Parotid metastasis was present in 50%, 32.4% showing parotid extracapsular spread, multivariate analysis found OR = 37.6 of positive parotid metastasis evolving into positive neck metastasis, p = 0.001. Occult neck metastasis, neck metastasis, and neck extracapsular spread were observed in 13.5%, 51.3%, and 37.8%, respectively. Kaplan-Meier survival: Clinical T4 versus T1, p = 0.028, P1 stage: 30% and 5% survival at 5 and 10 years, P3 stage: 0%, p = 0.016; OS and DSS showed negative survival for the parotid metastasis group, p = 0.0283. Conclusion: Our outcomes support a surgically aggressive approach for locally advanced and relapsed CSCC, with partial parotidectomy for P0, total parotidectomy for P1-3, selective I-III neck dissection for all patients and adjuvant radiochemotherapy to appropriately treat these patients with advanced CSCC of the head and neck region.

RESUMO

Abstract Objective: Goiters and benign nodules detected in the thyroid are growing lesions and the COVID-19 pandemic have negatively impacted on their surgical treatment. The appropriate selection of patients to treatment will improve the overall health status. This article review will focus on the impact of the COVID-19 pandemic on treatment of benign conditions of the thyroid gland and their implications. Methods: This review pointed out the status of the health system in developing country and the problems to treat benign surgical diseases of thyroid. Aspects of epidemiology, incidence, clinical presentation and surgical treatment of goiters, economic and health status impact were cited. Results: All surgical treatment of goiter and other benign conditions were postponed, forced to redirect, and reschedule all benign surgeries, situation aggravated by poor public management and closure of hospital beds. These conditions have caused deterioration in patients' physical (decompensated thyroid disease) and mental health status, increasing work disabilities and burdening society by increasing the social and health cost. The overall situation could be catastrophic in emergent countries where this increased disease-related social expenditure on surgical treatment may increase the risk of national impoverishment as increase the treatment cost. Brazilian Society Head and Neck Surgery related some recommendations and new suggestions were made to safely treat these high potential hazard surgical conditions. Conclusions: Surgeries for goiter and benign thyroid conditions can be performed during the COVID-19 pandemic, following strict safety protocols for the patient and the medical team, reducing the negative economic and on patient health impact.

Resumo Objetivo: Bócios e nódulos benignos detectados na tireoide são lesões em crescimento e a pandemia de Covid-19 impactou negativamente seu tratamento cirúrgico. A seleção adequada de pacientes para o tratamento vai melhorar o estado geral de saúde. Esta revisão de artigos se concentrará no impacto da pandemia de Covid-19 no tratamento de condições benignas da glândula tireoide e suas implicações. Método: Esta revisão evidenciou a situação do sistema de saúde em países em desenvolvimento e os problemas para tratar doenças cirúrgicas benignas da tireoide. Aspectos da epidemiologia, incidência, apresentação clínica e tratamento cirúrgico do bócio, impacto econômico e no estado de saúde foram relatados. Resultados: Todos os tratamentos cirúrgicos de bócio e outras condições benignas foram adiados, forçados a se redirecionar e a remarcar todas as cirurgias benignas, situação agravada pela má gestão pública e fechamento de leitos hospitalares. Essas condições têm causado deterioração do estado de saúde física (doença da tireoide descompensada) e mental dos pacientes, aumentam as incapacidades para o trabalho e sobrecarregando a sociedade e o custo social e de saúde. A situação geral pode ser catastrófica em países emergentes, onde esse aumento dos gastos sociais relacionados à doença sob tratamento cirúrgico pode aumentar o risco de empobrecimento nacional à medida que aumenta o custo do tratamento. A Sociedade Brasileira de Cirurgia de Cabeça e Pescoço forneceu algumas recomendações e novas sugestões foram feitas para tratar com segurança essas condições cirúrgicas de alto risco potencial. Conclusão: As cirurgias para bócio e condições benignas da tireoide podem ser feitas durante a pandemia de Covid-19, se forem seguidos rigorosos protocolos de segurança para o paciente e equipe médica, o que reduz o impacto negativo na economia e na saúde do paciente.

RESUMO

Abstract Introduction Surgical treatment of hyperparathyroidism related to chronic kidney disease is a real challenge for Brazilian public health care. High cost medications and long waiting lines to perform preoperative exams, especially technetium Tc 99m Sestamibi (MIBI) are some of the reasons. Despite the reality that the aid of localization exams are questionable in this scenario, doctors are too apprehensive in performing surgery without it. Objective The study aimed at evaluating the efficacy of surgery for renal hyperparathyroidism without preoperative MIBI. Methods A total of 114 patients were surgically treated. Total parathyroidectomy with autotransplantation and subtotal parathyroidectomy were carried out without preoperative MIBI. Results and conclusion Among the 114 patients undergoing surgery, 37 had secondary hyperparathyroidism in dialysis replacement, and 77 patients had post-renal transplant persistent disease. We were successful in 107 cases with only 7 failures (93.8% of success rate). Among these failures, only one parathyroid gland was not found in 4 cases, 2 parathyroid glands were not found in 2 cases and in 1 patient the 4 glands were found but this patient remained hypercalcemic and a postoperative diagnosis of supernumerary parathyroid gland was made. Surgery for treatment of renal hyperparathyroidism proved to be an effective (93.8%) and reproductible procedure, even without MIBI.

Resumo Introdução O tratamento cirúrgico do hiperparatireoidismo relacionado à doença renal crônica é um verdadeiro desafio para a saúde pública brasileira. Medicamentos de alto custo e longas filas de espera para exames pré‐operatórios, principalmente a cintilografia com tecnécio Tc‐99m Sestamibi, MIBI, são alguns dos motivos. Apesar da contribuição de exames de localização ser questionável nesse cenário, os médicos ficam muito apreensivos por fazer uma cirurgia sem ele. Objetivo Avaliar a eficácia da cirurgia para hiperparatireoidismo renal sem o MIBI pré‐operatório. Método Foram tratados cirurgicamente 114 pacientes. A paratireoidectomia total com autotransplante e a paratireoidectomia subtotal foram feitas sem MIBI pré‐operatório. Resultados e conclusão Entre os 114 pacientes submetidos à cirurgia, 37 apresentavam hiperparatireoidismo secundário em reposição dialítica e 77 doença persistente pós‐transplante renal. Tivemos sucesso em 107 casos, com apenas 7 falhas (93,8% de taxa de sucesso). Entre essas falhas, uma glândula paratireoide não foi encontrada em 4 casos, 2 glândulas paratireoides não foram encontradas em 2 casos e em um paciente as 4 glândulas foram encontradas, mas ele permaneceu hipercalcêmico com diagnóstico pós‐operatório de glândula paratireoide supranumerária. A cirurgia para tratamento do hiperparatireoidismo renal mostrou‐se um procedimento eficaz (93,8%) e reprodutível mesmo sem MIBI.

RESUMO

BACKGROUND: The symptomatic (swelling and pain) salivary gland obstructions are caused by sialolithiasis and salivary duct stenosis, negatively affecting quality of life (QOL), with almost all candidates for clinical measures and minimally invasive sialendoscopy. The impact of sialendoscopy treatment on the QOL has been little addressed nowadays. The objective is to prospectively evaluate the impact of sialendoscopy on the quality of life of patients undergoing sialendoscopy due to benign salivary obstructive diseases, measured through QOL questionnaires of xerostomia degree, the oral health impact profile and post sialendoscopy satisfaction questionnaires. RESULT: 37 sialendoscopies were included, most young female; there were 64.5% sialolithiasis and 35.4% post-radioiodine; with 4.5 times/week painful swelling symptoms and 23.5 months symptom duration. The pre- and post-sialendoscopy VAS values were: 7.42 to 1.29 (p < 0.001); 86.5% and 89.2% were subjected to sialendoscopy alone and endoscopic dilatation respectively; 80.6% reported improved symptoms after sialendoscopy in the sialolithiasis clinic (p < 0.001). The physical pain and psychological discomfort domain scores were mostly impacted where sialendoscopy provided relief and improvement (p < 0.001). We found a positive correlation between sialendoscopy and obstructive stone disease (p < 0.001) and no correlation in sialendoscopy satisfaction in xerostomia patients (p = 0.009). CONCLUSIONS: We found improved symptoms with overall good satisfaction after sialendoscopy correlated with stones; and a negative correlation between xerostomia. Our findings support the evident indication of sialendoscopy for obstructive sialolithiasis with a positive impact on QOL and probably a relative time-dependent indication for stenosis/other xerostomia causes that little improved QOL satisfaction. LEVEL OF EVIDENCE: 2b-Prospective non-randomized study. TRIAL REGISTRATION: WHO Universal Trial Number (UTN): U1111-1247-7028; Brazilian Clinical Trials Registry (ReBeC): RBR-6p8zfs.

RESUMO

Objective: To assess botulinum toxin-A (BTX-A) on mandibular movements and bite force (BF%) in bruxism.Methods: Ten bruxers were divided into 2 groups based on BF% imbalance (G1: >10%, G2: <10%). BTX-A 140U was total injected into the masseter and temporalis muscles. A T-Scan® recorded BF%, occlusion time (OT), right, left, and protrusive disclusion time (DT) before administering BTX-A, as well as 15, 45, 90, and 120 days after injection.Results: The Friedman and Wilcoxon tests found significant differences in BF% in G1 subjects at 15 days (p = 0.028 s), OT at 90 (p = 0.043 s), and 120 (p = 0.027 s) days, DTR at 90 (p = 0.046 s) and 120 (p = 0.028 s) days, DTL at 15 (p = 0.043 s) and 90 (p = 0.027 s) days, and DTP 45-90 days (p = 0.043 s).Conclusion: BTX-A induced BF% starting at 15 days post-injection and influenced lateralities later.

RESUMO

Mucoepidermoid carcinomas (MECs) are a form of salivary gland malignancy. They are classified according to histological grade and perineural invasion (PNI). In another cancer subtypes, positive-PNI suggests increased poor prognosis; however, the role of isolated positive-PNI salivary gland MEC can still be better investigated as a risk factor. This study investigated whether isolated PNI is independently associated with poor outcomes. Retrospective study, cohort case-series, single-center hospital from 2009 to 2019. Patient demographics, primary tumor, intervention, and survival data are included. Univariate, multivariate, and Kaplan-Meier survival curve analyses were used for comparison.The study group consisted of 32 patients (15 PNI-positive tumors, and 17 PNI-negative tumors), all admitted for surgery. Univariate analysis showed differences in grade (p = 0.038), positive margins (p = 0.034), soft tissue invasion (p < 0.001), pathological stage (p = 0.014), recurrence (p = 0.015), distant metastasis (p = 0.015) and MEC related death (p = 0.015). The risk in PNI-positive patients to develop soft tissue invasion and positive surgical margins was OR = 8.57 and OR = 4.88, respectively. Multivariate analysis found age differences (p = 0.038), with OR = 1.08. The Disease Specific Survival (DSS) was worst in the PNI-positive group (log-rank p-value = 0.0011), where the probability of dying occurred in the 12-24 months period (log-rank p-value = 0.002). PNI-positive salivary gland MEC is an independent prognostic factor, with poor DSS, increased locoregional recurrence, close correlation with a more aggressive pattern of the disease, and should be reviewed as a high grade histological criteria. Our findings may imply changes in the clinical approach with a more aggressive attitude in the overall treatment.

RESUMO

Abstract Introduction Upper aerodigestive tract cancer is among the most frequent malignancies and has epidemiological importance worldwide. Most cases are already advanced at the diagnosis, with a strong negative impact on survival and high cost to the government. Campaigns directed against these cancers have often failed in Brazil. Objective To evaluate the effectiveness of screening for upper aerodigestive tract cancers, using active search strategies and the use of equipped propaedeutics. Methods A cross-sectional, prospective, descriptive, analytical and exploratory study, since its objectives are based on the visualization of cancerous lesions in a sample consisting of individuals with risk factors, aiming to expand the necessary knowledge for cancer detection, aiming at secondary prevention of the oral cavity, oropharynx, larynx and hypopharynx cancer. Results A total of 16.7% of precancerous lesions and 0.5% of cancer lesions located in the upper aerodigestive tract were clinically visualized. Conclusion The method was effective in the identification of precancerous lesions for the purpose of secondary prevention, but equally important against upper aerodigestive tract cancer, since in the present study the chance of finding the latter was increased by 22.7, showing it is an alternative for future campaigns against the disease.

RESUMO

Introduction: Surgical management of thyroid disease in children presents several peculiarities and has increasingly developed in recent years, but historically few studies conducted with this population have been published. Objective: Analysis of the surgical approach and postoperative outcomes of 59 pediatric patients submitted to thyroidectomy between 2003 and 2019. Methods: An outpatient postoperative follow-up of 59 patients aged 3-18 years submitted to thyroidectomy for different causes was performed, and immediate and late postoperative outcomes were analyzed. The operations were performed at a University Hospital as well as at Private Tertiary Hospitals. Results: The following postoperative outcomes were observed: three tracheostomies, 22 patients with transient hypoparathyroidism, eight patients with definitive hypoparathyroidism, and three patients with vocal fold paralysis. Conclusion: Thyroidectomy in children is a procedure with a higher complication rate and needs to be performed by a team of high-volume surgeons. This study focuses on the adverse events, so that those interested in the subject are aware of them.

RESUMO

OBJECTIVES: To investigate whether disclosed symptoms (coughing, choking and throat clearing) can be used as early predictors of swallowing disorders in non-hospitalized elderly population. In addition, to determine the presence of early findings of swallowing disorders through fiber optic endoscopic evaluation of swallowing (FEES). MATERIALS AND METHODS: One hundred subjects older than 60 years were recruited from local community social meetings for seniors, they fulfilled inclusion criteria, and were given an oral interview and underwent FEES, with findings classified as: (1) saliva stasis; (2) pharyngeal residue; (3) penetration; (4) aspiration; (5) laryngeal sensitivity. RESULTS: Twenty-one percent of subjects declared previous choking, 10% coughing, and 7% throat clearing, 39% had pharyngeal residue; 6% saliva stasis; 9% penetration; 2% aspiration; and 92% laryngeal sensitivity present. Thirty-three percent showed pharyngeal residue without saliva stasis, while only 6% showed positivity for both (p = 0.003). CONCLUSIONS: Our data suggest that health care professionals should be aware that among an apparently healthy population, some subjects may have swallowing disorders without clinical complaints and that a nasolaryngoscopy exam may not be enough to predict dysphagia. We suggest that FEES should be performed to look for surrogate of dysphagia such as pharyngeal residue, laryngeal penetration, and aspiration.

RESUMO

Salivary gland neoplasms are a relatively uncommon disease, with nearly one case per 100.000 adults estimated per year and an overall incidence of 1% of all neoplasms. The benign neoplasms are majority and the prognosis depends on the histologic type, grade, localization, soft tissue infiltration, regional and distant metastasis. The main treatment is surgery with caution to facial nerve in the major salivary glands, followed by radiotherapy and chemotherapy in selected cases. The objective of this review is to provide the lector an historic approach about salivary gland diseases treatment, with special attention to the parotid neoplasms and its peculiarities associated to those who studied these glands in their history course.

As neoplasias das glândulas salivares são relativamente raras, compreendendo cerca de 1% das neoplasias de todo corpo, com incidência de 1/100.000 habitantes por ano. As neoplasias benignas predominam sobre as malignas. O prognóstico depende muito do tipo histológico, grau de diferenciação, localização, infiltração de tecidos vizinhos e da presença de metástases regionais ou a distância. O principal tratamento ainda é a cirurgia, com os seus desafios e dificuldades, devido aos ramos do nervo facial nas glândulas salivares maiores, seguido de radioterapia e em casos selecionados quimioterapia adjuvante. O objetivo desta revisão é fornecer ao leitor uma abordagem histórica sobre o tratamento das doenças das glândulas salivares, com especial atenção às doenças da glândula parótida assim como peculiaridades associadas aqueles que as estudaram ao longo da história.
