    Loss of an eye to mucormycosis following corticosteroid therapy for COVID-19
    (2022) RODRIGUES, M. G.; SEKIGUCHI, W. K.; GONçALVES, S.; CASAL, Y. R.; FRASSETTO, F. P.; SILVA, V. T. G. da; SANTO, M. P. D. E.; MAGRI, M. M. C.
    Mucormycosis is a rare, sometimes severe fungal infection that has emerged as a possible complication of COVID-19. We report a case of a non-diabetic, apparently immunocompetent patient diagnosed with rhino-orbital-cerebral mucormycosis shortly after COVID-19 treatment with dexamethasone. The patient received optimized systemic antifungal therapy and extensive surgical treatment. So far, four months after the last hospital discharge, the patient has been in good general condition. This case is a dramatic reminder that beneficial corticosteroid therapy in general inevitably carries a risk of opportunistic infection, and corticosteroid therapy for COVID-19 risks orbital-rhinocerebral mucormycosis that clinicians should watch for with vigilance. © 2021 The Author(s).

    Incidental thyroid carcinoma: Correlation between FNAB cytology and pathological examination in 1093 cases
    (2022) RODRIGUES, Mariana Goncalves; SILVA, Luiz Fernando Ferraz da; ARAUJO-FILHO, Vergilius Jose Furtado de; MOSCA, Leticia de Moraes; ARAUJO-NETO, Vergilius Jose Furtado de; KOWALSKI, Luiz Paulo; CARNEIRO, Paulo Campos
    Objective: To investigate Incidental Thyroid Carcinoma (ITC) by comparing the results of Fine Needle Aspiration Biopsy (FNAB) cytology and the postoperative pathological findings. Methods: Data of 1479 patients who underwent total thyroidectomy were retrieved. Three hundred eighty-six patients were excluded due to insufficient data. Each surgical specimen studied received two histopathological diagnoses: the local diagnosis - for the same area in which the FNAB was performed; and the final diagnosis, which includes a study of the entire surgical specimen. Results: A thousand and ninety-three patients were investigated. FNAB result was malignant in 187 patients, benign in 204, suspicious or indeterminate in 668 cases, and inconclusive in 34 cases. The prevalence of ITC was 15.1%. Most of the ITC in this series was less than 0.5 cm. The incidence of ITC was higher in Bethesda III (17.5% ITC) and IV (19% ITC) than in Bethesda II cases (1.5% false negatives and 9% ITC). Conclusion: Although the incidence of false-negative results in Bethesda II nodules is only 1.5%, 9% of these patients had ITC in the thyroid parenchyma outside the nodule that underwent preoperative FNAB. The incidence of ITC in the same scenario was even higher in Bethesda III (17.5%) and Bethesda IV cases (19%). Ultrasonography-guided FNAB is an excellent method for the assessment of thyroid nodules. However, biopsy sites should be carefully selected. Despite the high incidence of incidentalomas, total thyroidectomy should not always be the treatment of choice due to its rare but potentially serious complications. The findings of the present study can assist future clinical decisions towards active surveillance strategies for the management of papillary thyroid carcinoma.

    Substernal goiter and laryngopharyngeal reflux
    (2017) RODRIGUES, Mariana Gonçalves; ARAUJO FILHO, Vergilius José Furtado de; MATOS, Leandro Luongo de; HOJAIJ, Flávio Carneiro; SIMÕES, Cesar Augusto; ARAUJO NETO, Vergilius José Furtado de; RAMOS, Daniel Marin; MAHMOUD, Renata Lorencetti; MOSCA, Letícia de Moraes; MANTA, Gustavo Borges; VOLPI, Erivelto Martinho; BRANDÃO, Lenine Garcia; CERNEA, Claudio Roberto
    ABSTRACT Objective This study aims to compare the prevalence of laryngopharyngeal reflux signs between two groups of patients undergoing thyroidectomy for voluminous goiter: substernal goiters and voluminous cervical goiter without thoracic extension. Subjects and methods A retrospective case-control study was performed with data retrieved of the charts of the patients submitted to thyroidectomies occurred at a tertiary care center (Head and Neck Surgery Department, University of São Paulo Medical School) between 2010 and 2014. The selected thyroidectomies were allocated in two groups for study: patients with substernal goiters and patients with voluminous cervical goiter without thoracic extension. Cervical goiters were selected by ultrasonography mensuration. Clinical criterion was used to define substernal goiter. Results The average thyroid volume in patients with substernal goiter was significantly greater than the average volume in patients with only cervical goiter (p < 0.001). The prevalence of signs of reflux laryngitis at laryngoscopy was significantly greater in substernal goiter patients (p = 0.036). Moreover, substernal goiter was considered as the unique independent variable for high reflux laryngitis signs at laryngoscopy (OR = 2.75; CI95%: 1.05-7.20; p = 0.039) when compared to only cervical goiter patients. Conclusion This study shows a significant association between substernal goiters and signs of laryngopharyngeal reflux at preoperative laryngoscopy. Therefore, when compared with voluminous cervical goiters, the substernal goiters increase the chance of reflux laryngitis signs in patients.
