Planned parathyroidectomy: the new standard in hypercalcemic crisis.

Objective: The study sought to determine the clinical features of hyperparathyroid-induced hypercalcemic crisis (HIHC) along with treatment options and outcomes. Subjects and methods: This is a retrospective analysis of our historical cohort of patients with primary hyperparathyroidism (PHPT). Patients were divided in groups according to their calcium levels and clinical presentation. HIHC (group 1) was assumed when patients had high calcium levels and needed emergency hospitalization. Group 2 was composed of patients with calcium levels above 16 mg/dL or patients who needed hospitalization for classical PHPT symptoms. Group 3 was composed of clinically stable patients with calcium levels between 14 and 16 mg/dL, who were electively treated. Results: Twenty-nine patients had calcium levels above 14 mg/dL. HIHC group had seven patients, and initial clinical measures had good response in two patients, moderate response in one patient, and poor response in four patients. All poor responders underwent immediate surgery, and one of them died due to HIHC complications. Group 2 had nine patients, and all were successfully treated during hospitalization. Group 3 had 13 patients, and all had a successful elective surgery. Conclusion: HIHC is a life-threatening condition that requires fast clinical intervention. Surgery is the only definitive treatment and should be planned for all patients. Poor response to initial clinical measures should direct treatment toward surgery to avoid disease progression and clinical deterioration.

Parotidectomy and neck dissection in locally advanced and relapsed cutaneous squamous cell carcinoma of the head and neck region,,

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.

Sestamibi scan in renal parathyroidectomy: a worthwhile preoperative exam? / Cintilografia com sestamibi na paratireoidectomia renal: um exame pré‐operatório que vale a pena?

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.

Quality of life after sialendoscopy: prospective non-randomized study.

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.

Perineural Invasion as Worsening Criterion for Salivary Gland Mucoepidermoid Carcinoma.

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.

Prediction of bone mass changes after successful parathyroidectomy using biochemical markers of bone metabolism in primary hyperparathyroidism: is it clinically useful?

OBJECTIVE: To measure type 1 serum amino-terminal propeptide procollagen (P1NP) and type 1 cross-linked C-terminal telopeptide collagen (CTX) before parathyroidectomy (PTX) in PHPT patients, correlating these measurements with bone mineral density (BMD) changes. SUBJECTS AND METHODS: 31 primary hyperparathyroidism (HPTP) were followed from diagnosis up to 12-18 months after surgery. Serum levels of calcium, parathyroid hormone (PTH) vitamin D, CTX, P1NP, and BMD were measured before and 1 year after surgery. RESULTS: One year after PTX, the mean BMD increased by 8.6%, 5.5%, 5.5%, and 2.2% in the lumbar spine, femoral neck (FN), total hip (TH), and distal third of the nondominant radius (R33%), respectively. There was a significant correlation between BMD change 1 year after the PTX and CTX (L1-L4: r = 0.614, p < 0.0003; FN: r = 0.497, p < 0.0051; TH: r = 0.595, p < 0.0005; R33%: r = 0.364, p < 0.043) and P1NP (L1-L4: r = 0,687, p < 0,0001; FN: r = 0,533, p < 0,0024; TH: r = 0,642, p < 0,0001; R33%: r = 0,467, p < 0,0079) preoperative levels. The increase in 25(OH)D levels has no correlation with BMD increase (r = -0.135; p = 0.4816). On linear regression, a minimum preoperative CTX value of 0.331 ng/mL or P1NP of 37.9 ng/mL was associated with a minimum 4% increase in L1-L4 BMD. In TH, minimum preoperative values of 0.684 ng/mL for CTX and 76.0 ng/mL for P1NP were associated with a ≥ 4% increase in BMD. CONCLUSION: PHPT patients presented a significant correlation between preoperative levels of turnover markers and BMD improvement 1 year after PTX.

Localization of ectopic and supernumerary parathyroid glands in patients with secondary and tertiary hyperparathyroidism: surgical description and correlation with preoperative ultrasonography and Tc99m-Sestamibi scintigraphy.

INTRODUCTION: Hyperparathyroidism is an expected metabolic consequence of chronic kidney disease (CKD). Ectopic and/or supernumerary parathyroid glands (PT) may be the cause of surgical failure in patients undergoing total parathyroidectomy (PTX). AIM: To define the locations of ectopic and supernumerary PT in patients with renal hyperparathyroidism and to correlate intraoperative findings with preoperative tests. MATERIALS AND METHODS: A retrospective study was conducted with 166 patients submitted to PTX. The location of PT during surgery was recorded and classified as eutopic or ectopic. The preoperative localizations of PT found by ultrasonography (USG) and Tc99m-Sestamibi scintigraphy (MIBI) were subsequently compared with intraoperative findings. RESULTS: In the 166 patients studied, 664 PT were found. Five-hundred-seventy-seven (86.4%) glands were classified as eutopic and 91(13.6%) as ectopic. Eight supernumerary PT were found. The most common sites of ectopic PT were in the retroesophageal and thymic regions. Taken together, USG and MIBI did not identify 56 (61.5%) ectopic glands. MIBI was positive for 69,7% of all ectopic glands located in the mediastinal and thymic regions. CONCLUSION: The presence of ectopic and supernumerary PT in patients with renal hyperparathyroidism is significant. Although preoperative imaging tests did not locate most of ectopic glands, MIBI may be important for identifying ectopic PT in the mediastinal and thymic regions.

Localizacao de glandulas paratireoides ectopicas e supranumerarias em pacientes com hiperparatireoidismo secundario e terciario: descricao cirurgica e correlacao com ultrassonografia e cintilografia Tc99m-Sestamibi pre-operatorios / Localization of ectopic and supernumerary parathyroid glands in patients with secondary and tertiary hyperparathyroidism: surgical description and correlation with preoperative ultrasonography and Tc99m-Sestamibi scintigraphy

Introdução: O hiperparatireoidismo é uma consequência metabólica esperada na doença renal crônica (DRC). Paratireoides (PT) ectópicas e/ou supranumerárias podem ser causa de falha cirúrgica nos pacientes submetidos à paratireoidectomia total (PTX). Objetivo: Definir cirurgicamente a localização das PT, em pacientes com hiperparatireoidismo associado à DRC, e correlacionar esses achados com os exames pré-operatórios. Materiais e métodos: Foi conduzido um estudo retrospectivo com 166 pacientes submetidos à PTX. A localização das PT no intraoperatório foi registrada, sendo classificada como tópica ou ectópica. A localização pré-operatória, definida pela ultrassonografia (USG) e pela cintilografia Tc99m-Sestamibi (MIBI), foi comparada com aos achados cirúrgicos. Resultados: Nos 166 pacientes, foram identificadas 664 PT. Foram classificadas como tópicas e ectópicas 577 (86,4%) e 91(13,6%) glândulas, respectivamente. Oito PT supranumerárias foram encontradas (7 tópicas e 1 ectópica). As localizações mais comuns de PT ectópicas foram as regiões retroesofágica e tímica. Associadas, a USG e a MIBI não identificaram 56 glândulas (61,5%) ectópicas. Entretanto, a MIBI foi positiva para 69,7% daquelas localizadas nas regiões tímicas e mediastinal. Conclusão: A presença de glândulas ectópicas e supranumerárias em pacientes com hiperparatireoidismo associado à DRC é significativa. Os exames de imagem pré-operatórios não localizaram a maioria das glândulas ectópicas. A MIBI pode ter importância na identificação de PT nas regiões tímica e mediastinal. .

A critical analysis of 33 patients with substernal goiter surgically treated by neck incision.

UNLABELLED: The possibility of needing a combined access, with neck and chest incisions makes the treatment of substernal goiter a challenge both in the pre-op and the intraoperative. We hereby, discuss a standardization of the surgical technique to minimize the need for a chest approach, making the substernal goiter a surgically treatable disease, through a single neck incision, and with low indices of complication. AIM: To assess the substernal goiter surgically approach through a neck incision and to analyze the surgical complications. MATERIALS AND METHODS: We carried out a historical cohort by retrospective analysis of the charts of patients submitted to thyroidectomy, and 33 of them (10.4%) had substernal goiter. RESULTS: All 33 patients were surgically treated through a neck incision without the need for sternotomy. We did not observe definitive lesions in the inferior laryngeal nerve or definitive hypoparathyroidism. Only 2 patients had recurrent nerve paresis; and 2 patients were re-operated because of a neck hematoma. CONCLUSION: Patients with substernal goiter can be safely treated surgically through a single neck incision, bearing low complication rates.

Avaliação crítica de 33 pacientes com bócio mergulhante tratados cirurgicamente por cervicotomia / A critical analysis of 33 patients with substernal goiter surgically treated by neck incision

A possibilidade de ser necessário um acesso combinado, com uma incisão cervical e outra torácica, torna o tratamento do bócio mergulhante um desafio tanto no pré quanto no intra-operatório. Discutimos uma padronização da técnica cirúrgica para minimizar a necessidade da abordagem torácica, tornando o bócio mergulhante uma patologia tratável cirurgicamente, por uma única incisão cervical, e com baixos índices de complicações. OBJETIVO: Avaliar a abordagem cirúrgica do bócio mergulhante por cervicotomia e analisar as complicações cirúrgicas. MATERIAL E MÉTODOS: Foi realizada uma coorte histórica com corte transversal por análise retrospectiva dos prontuários de pacientes submetidos à tireoidectomia no período de maio de 2002 a julho de 2007. Um total de 316 pacientes foi submetido à tireoidectomia sendo 33 (10,4 por cento) por bócio mergulhante. RESULTADOS: Todos os 33 pacientes foram tratados cirurgicamente por via cervical sem necessidade de esternotomia. Não foram observadas lesões definitivas de nervo laríngeo inferior ou hipoparatireoidismo definitivo. Apenas 2 pacientes apresentaram paresia de nervo recorrente e 2 pacientes foram reabordados por hematoma cervical. CONCLUSÃO: Pacientes com bócio mergulhante podem ser tratados cirurgicamente por uma única incisão cervical com segurança e baixos índices de complicação.
