ABSTRACT
ABSTRACT INTRODUCTION: Sialendoscopy is becoming the gold standard procedure for diagnosis and treatment of Salivary Gland Inflammatory Diseases. OBJECTIVE: To evaluate the learning progression of a single surgeon to implement and perform diagnostic sialendoscopy: to estimate how many procedures were necessary to achieve better results; if it was higher rate of complications in the beginning. METHODS: Retrospective analysis involving 113 consecutive sialendoscopies performed from 2010 to 2013. According to a descriptive analysis of the factors related to surgeon's experience, the casuistic was divided into two groups: group (A) comprising the first 50 exams, and group (B) the last 63. Groups were then compared concerning demographic and peri-operative aspects. RESULTS: In Group A, failure to catheterize papilla were 22% versus 3% in B (p = 0.001). Failure to complete examination was 30% in group A versus 6% in B (p = 0.001), and necessity to repeat exams was 22% in group A versus 10% in B (p = 0.058). The complication rates were 18% in group A, and 10% in B (p = 0.149). Operative time was slightly shorter in group B (56 versus 41 min, p = 0.045). CONCLUSION: We found better outcomes after the first 50 diagnostic sialendoscopies. Complication rates were statistically the same between early and late groups of experience with sialendoscopy.
RESUMO INTRODUÇÃO: A sialoendoscopia vem se tornando o procedimento de referência para o diagnóstico e o tratamento das doenças inflamatórias da glândula salivar. OBJETIVO: Avaliar a progressão de aprendizado de um mesmo cirurgião para implementação e realização da sialoendoscopia diagnóstica: verificar quantos procedimentos foram necessários para a obtenção de resultados melhores e se houve ocorrência de maior taxa de complicações no início do aprendizado. MÉTODO: Análise retrospectiva envolvendo 113 sialoendoscopias consecutivas realizadas de 2010 a 2013. De acordo com uma análise descritiva dos fatores relacionados à experiência do cirurgião, a casuística foi dividida em dois grupos: grupo (A), compreendendo os primeiros 50 exames; e grupo (B), os últimos 63. Em seguida, os grupos foram comparados, levando em consideração os aspectos demográficos e perioperatórios. RESULTADOS: No grupo A, a não realização do cateterismo papilar foi de 22% vs. 3% em B (p = 0,001). A não realização de um exame completo foi de 30% no grupo A vs. 6% em B (p = 0,001), e a necessidade de repetir o exame foi de 22% no grupo A vs. 10% em B (p = 0,058). Os percentuais de complicações foram 18% no grupo A e 10% em B (p = 0,149). O tempo operatório foi ligeiramente menor no grupo B (56 vs. 41 minutos, p = 0,045). CONCLUSÃO: Verificamos melhores desfechos após as 50 primeiras sialoendoscopias diagnósticas. Os percentuais de complicações foram estatisticamente semelhantes entre os grupos inicial e avançado de experiência com a sialoendoscopia.

Hypercalcemia is found frequently in patients with cancer. Besides the etiology related to the malignancy, other causes should be considered in the differential diagnostic, as primary hyperparathyroidism, granulomatous diseases and the use of thiazide diuretics. We present a case report of a severe hypercalcemia due to a rare association and review the relevant literature. A female patient, 57 years old, sent to the Endocrinology Service of Hospital das Clínicas da Universidade do Paraná (SEMPR) in order to investigate severe hypercalcemia with frequent need of hospitalization. The patient was in chemotherapy treatment for recurrence of clear cell renal cancer. During the investigation she presented high level of parathyroid hormone (PTH) and parathyroid scintigraphy suggestive of hyperplasia/ adenoma of parathyroid, histopathological diagnosis was confirmed after parathyroidectomy. After surgery the patient presented undetectable levels of PTH. However, she continued with progressive increase of serum calcium, with no signs of bone metastases or change in vitamin D metabolism. The investigation showed high levels of PTH-related protein (PTHrP), leading us to the diagnosis of hypercalcemia of malignancy. The patient presented severe hypercalcemia due to the rare association of primary hyperparathyroidism and humoral hypercalcemia of malignancy due to secretion of PTHrP by tumor cells. The presence of isolated primary hyperparathyroidism, as a cause of hypercalcemia in cancer patients, has been described in approximately 5-10% of the patients. However, the association of primary hyperparathyroidism and humoral hypercalcemia of malignancy (which means with concomitant elevation of PTH and PTHrP) is rare, only three cases have been described in the literature.

Introdução: A paratireoidectomia total com autotransplante imediato é utilizada no tratamento do hiperparatireoidismo renal. A descrição inicial do autotransplante de paratireoide utilizou vinte lojas com um fragmento em cada loja. Objetivo: O presente estudo analisa aspectos técnicos e funcionais de um método simplificado de autotransplante. Método: Análise retrospectiva do tempo empregado para realizar o implante de paratireoide pela técnica tradicional (grupo A, 18 to 20 lojas) e pela simplificada (grupo B, 5 lojas). A função do tecido autotransplantado foi avaliada de acordo com os níveis sistêmicos do paratormônio (PTH). A função do implante foi classificada em quatro grupos, de acordo com os níveis de PTH, como a seguir: estado funcional 1 (EF1), PTH abaixo da faixa normal para o método; estado funcional 2 (EF2), PTH dentro dos limites da normalidade; estado funcional 3 (EF3), PTH elevado não mais que três vezes o limite superior da normalidade e estado funcional 4 (EF4), PTH elevado acima de três vezes o limite superior da normalidade. Resultados: No grupo A, o tempo empregado para realizar o auto-implante variou de 30 a 60 minutos (média 44,0) e no grupo B, o tempo variou de 10 a 30 minutos (média 18,6) (p< 0,0001). A mediana do nível sistêmico do PTH foi de 43,1 pg/mL no grupo A e 39pg/mL no grupo B. A distribuição dos estados funcionais no grupo A e B foram, respectivamente: EF1 17% e14,6%; EF2 50% e 58,5%; EF3 23% e 22%; EF4 10% e 4,9%. (p=0,8). Conclusões: A redução do número de lojas criadas para autotransplante de paratireoide para cinco lojas não afetou o estado funcional e reduziu o tempo empregado para o implante.
Introduction: Total parathyroidectomy with immediate autotransplantation is employed in the management of renal hyperparathyroidism. The initial description of parathyroid autotransplantation employed twenty pockets with one fragment of parathyroid in each pocket. Objective: The present study analyzes technical and functional aspects of a simplified method of autotransplantation. Methods: Retrospective analysis of time spent to perform a traditional (Group A, 18 to 20 pockets) parathyroid autotransplantation and a simplified (Group B, 5 pockets) technique. The function of the transplanted tissue was evaluated according to systemic levels of parathyroid hormone (PTH). Graft function was classified into four groups according to PTH levels, as follows: Implant Functional Status 1(FS1): PTH below the normal range; FS2: PTH within the normal range; FS3:PTH elevated to no more than three times the upper limit, and FS4: PTH levels more than three times the upper limit. Results: In Group A, the time spent to perform the autograft varied from 30 to 60 minutes (mean 44.0) and in Group B it varied from 10 to 30 min (mean 18.6) (p< 0.0001). The median level of postoperative systemic PTH was 43.1 pg/mL in group A and 39 pg/mL in group B. Functional status distribution in Group A and B were, respectively: FS1 17% and 14.6%; FS2 50% and 58.5%; FS3 23% and 22%; FS4 10% and 4.9%. (p=0.8). Conclusions: The reduction of the number of pockets created for parathyroid autotransplantation to five pockets did not affect parathyroid transplant functional status and reduced the time spent for implantation.
