RESUMEN El hiperparatiroidismo es una enfermedad eminentemente clínica que se presenta cuando existe un aumento en la producción de hormona paratiroidea, superior a las necesidades que el organismo requiere, dando lugar a hipercalcemia, trastornos óseos y renales en un grado variable. Se presenta el caso de un paciente de 64 años con hiperparatiroidismo secundario a un adenoma paratiroideo que fue diagnosticado por hallazgo casual, posterior a que el paciente venía presentando dolores óseos frecuentes de más de un año de evolución. Durante su internación se obtuvo el diagnóstico de adenoma paratiroideo por lo que fue intervenido quirúrgicamente con exéresis y tratamiento ambulatorio. ABSTRACT Hyperparathyroidism is an eminently clinical disease that occurs when there is an increase in the production of parathyroid hormone, greater than the needs that the body requires, leading to hypercalcemia, bone and kidney disorders to a variable degree. We present the case of a 64-year-old patient with hyperparathyroidism secondary to a parathyroid adenoma that was diagnosed by chance finding, after the patient had been presenting frequent bone pain of more than a year of evolution. During his hospitalization, a diagnosis of parathyroid adenoma was obtained, for which he underwent surgery with excision and outpatient treatment.

RESUMEN El hiperparatiroidismo terciario se caracteriza por hipercalcemia e hiperparatiroidismo autónomo en el contexto de hiperparatiroidismo secundario persistente. El HPT3 se relaciona con calcificaciones extraesqueléticas o calcifilaxis, fracturas, dolor óseo, pérdida progresiva de la densidad mineral ósea, nefrocalcinosis, litiasis, disfunción o rechazo del aloinjerto, alteraciones neuropsiquiátricas, enfermedad cardiovascular y aumento de la morbimortalidad. La paratiroidectomía subtotal es el tratamiento de elección, con altas tasas de curación. Presentamos el caso de una paciente con hiperparatiroidismo terciario como enfermedad ósea metabólica después de un trasplante renal exitoso, con evolución insidiosa y daño óseo severo, con adecuada respuesta al tratamiento oportuno con paratiroidectomía subtotal. El diagnóstico y tratamiento oportuno del hiperparatiroidismo terciario en el paciente con trasplante renal es fundamental para disminuir la incidencia de comorbilidades, mejorar el pronóstico del paciente y optimizar recursos de salud. ABSTRACT Tertiary hyperparathyroidism (THPT) is characterized by hypercalcemia and autonomous hyperparathyroidism in the context of persistent secondary hyperparathyroidism (SHPT). THPT is related with extraskeletal calcifications, calciphylaxis, fractures, bone pain, progressive loss of bone mineral density, nephrocalcinosis, lithiasis, kidney allograft dysfunction and rejection, neuropsychiatric alterations, cardiovascular disease, and high morbimortality. Subtotal parathyroidectomy is the gold standard for treatment, with high cure rates. We described a case of THPT as a manifestation of Bone Mineral Metabolism Disease after a successful kidney transplant, with an insidious evolution and severe bone damage, with an adequate response to subtotal parathyroidectomy. We evidenced that early diagnosis and treatment of THPT in kidney transplant recipients is essential to the diminution of comorbidities, the improvement of prognosis and the optimization of health resources.

Existen numerosas causas de hipercalcemia que exigen un amplio diagnóstico diferencial, entre las que se encuentra el adenoma paratiroideo, una etiología rara en la edad pediátrica. El adenoma paratiroideo produce un incremento de hormona paratiroidea (PTH) que desencadena hipercalcemia mediante aumento de la absorción gastrointestinal y tubular renal de calcio, y mayor resorción ósea. El tratamiento inicial tiene como objetivo reducir la calcemia y el tratamiento definitivo consiste en la exéresis quirúrgica del adenoma, ayudada de monitorización de niveles intraoperatorios de PTH. Se presenta el caso de una paciente de diez años, con hallazgo de hipercalcemia en un estudio de dolor abdominal de larga evolución, que en los últimos días asociaba vómitos, anorexia, poliuria y polidipsia. Se trata de un hiperparatiroidismo debido a un adenoma paratiroideo en el que fue necesario utilizar todos los escalones terapéuticos de la hipercalcemia, concluyendo finalmente con la exéresis quirúrgica del adenoma. There are numerous causes of hypercalcemia, which require a wide differential diagnosis, including parathyroid adenoma, a rare etiology in the pediatric age. Parathyroid adenoma produces an increase in parathyroid hormone (PTH) that triggers hypercalcemia by increasing gastrointestinal and tubular calcium absorption and increased bone resorption. The initial treatment aims to reduce the calcemia and the definitive treatment consists in the surgical excision of the adenoma, aided of monitoring of intraoperative levels of PTH. We present the case of a 10-year-old patient with a finding of hypercalcemia in the study of abdominal pain of long evolution, which associated vomiting, anorexia, polyuria and polydipsia. It is a hyperpar-athyroidism due to a parathyroid adenoma in which it was necessary to use all the therapeutic steps of hypercalcemia finally concluding with surgical excision of the adenoma.

Objetivo: Describir un caso de hiperparatiroidismo inducido por litio. Caso Clínico: Paciente femenina de 62 años de edad referida para evaluación de hipercalcemia persistente. Refería diagnóstico de trastorno bipolar tratado con litio durante 10 años. Negaba síntomas de hiperparatiroidismo. El examen físico estuvo dentro de los límites normales. Las pruebas de laboratorio demostraron concentraciones séricas elevadas de calcio y parathormona. La densitometría ósea estaba disminuida. La tomografía computarizada mostró lesión paratiroidea izquierda de aproximadamente 5 milímetros. La gammagrafía con sestamibi con tecnecio-99m mostró retención de isótopos en el polo inferior izquierdo de la glándula tiroides. Todos estos hallazgos llevaron a la posibilidad diagnóstica de hiperparatiroidismo inducido por litio. Se suspendió el tratamiento y se inició el uso de calcimiméticos, pero después de 2 meses, debido a una recaída del trastorno psiquiátrico fue sometida a paratiroidectomía. Durante el postoperatorio, las concentraciones séricas de calcio y parathormona volvieron a la normalidad. Se reanudó el tratamiento con litio para controlar los síntomas psiquiátricos. Conclusión: El litio es un tratamiento efectivo para algunas condiciones psiquiátricas. Uno de los efectos secundarios es sobre las glándulas paratiroides y puede causar exacerbación del hiperparatiroidismo preexistente o causar función alterada de la parathormona, lo que lleva a la hiperplasia paratiroidea. La prevalencia de la enfermedad multiglandular es alta y no existe consenso sobre el tratamiento específico y la reanudación del litio. En casos de hipercalcemia no controlada o fracaso del tratamiento médico, se debe realizar la paratiroidectomía. Objective: To describe a case of lithium-induced hyperparathyroidism. Clinical case: A 62-year-old female patient who was referred for evaluation of persistent hypercalcemia. She reported a diagnosis of bipolar disorder treated with lithium for 10 years. She denied symptoms of hyperparathyroidism. The physical examination was within normal limits. Laboratory tests demonstrated elevated serum calcium and parathormone concentrations. Bone densitometry was decreased. Computed tomography showed a left parathyroid lesion of approximately 5 millimeters. Technetium-99m sestamibi scintigraphy showed isotope retention in the lower-left pole of the thyroid gland. All of these fi ndings led to the diagnostic possibility of lithium-induced hyperparathyroidism. The treatment was suspended and the use of calcimimetics was started, but after 2 months, due to a relapse of the psychiatric disorder, she underwent parathyroidectomy. During postoperative period, serum calcium and parathormone concentrations returned to normal. Lithium treatment was resumed to control psychiatric symptoms. Conclusion: Lithium is an effective treatment for some psychiatric conditions. One of the side effects is on the parathyroid glands, and can cause exacerbation of pre-existing hyperparathyroidism or cause impaired parathormone suppression, leading to parathyroid hyperplasia. The prevalence of the multiglandular disease is high and there is no consensus on the specifi c treatment and resumption of lithium. In cases of uncontrolled hypercalcemia or failure of medical treatment, a parathyroidectomy must be performed. 61-66 sippenbauch@gmail.com Cuatrimestral http://www.saber.ula.ve/rvem/

- Abstract
Background: Brown tumors of bones are an uncommon manifestation of hyperparathyroidism. Case report: We report a 35 years old male presenting with pain and paresis of the left superior limb. Part of his humerus was excised due to a diagnosis of a giant cell tumor. He was admitted again to the hospital due to pelvic pain, malaise and constipation. A right cervical nodule was found. Laboratory evaluation confirmed the presence of a hyperparathyroidism. The biopsy of the pelvic lesion disclosed a brown tumor. The patient was subjected to a parathyroidectomy and the pathological study of the surgical piece showed a right parathyroid adenoma and a right thyroid papillary micro carcinoma. In the postoperative period the patient had a hungry bone syndrome, which was adequately treated. [ABSTRACT FROM AUTHOR]

RESUMEN Introducción y objetivos: Describir la etiopatogenia y el diagnóstico diferencial entre el hiperparatiroidismo primario y otras causas de hipercalcemia. Material y métodos: Revisión narrativa. Resultados: El hiperparatiroidismo primario (HPP) es una enfermedad endocrina frecuente, que se define de forma convencional como la existencia de hipercalcemia en presencia de niveles elevados de hormona paratiroidea (PTH). Conclusiones: Aunque la forma más común de presentación en la actualidad sea como hipercalcemia asintomática, la elevada morbilidad asociada con esta patología requiere que se realice un diagnóstico precoz y preciso, tanto de la etiología como de sus complicaciones, para poder llevar a cabo un manejo adecuado de los pacientes afectados.

Primary hyperparathyroidism is an endocrine disorder characterized by hypercalcemia and elevated or inappropriately normal levels of parathyroid hormone. The diagnosis is based on a biochemical evaluation, and a neck ultrasound is the first choice during pregnancy to access the parathyroid glands. Manifestations during pregnancy are rare and can be present with life-threatening complications, so the diagnosis is challenging. The conservative treatment is limited, and there is not enough data about its safety and efficacy during pregnancy. Surgery is the only curative treatment, and a parathyroidectomy performed during the second or third trimesters is considered safe. Recently, some authors suggested an association between primary hyperparathyroidism and preeclampsia. We describe a case of preeclampsia with severe features at 27 weeks of gestational age. The severity of the preeclampsiamotivated an early termination of the pregnancy by cesarean section. During the postpartum period, the patient presented life-threatening complications, such as severe hypercalcemia and acute pancreatitis. An ultrasound exam found two parathyroid nodules, suggestive of parathyroid adenomas. The patient recovered after the pharmacological correction of the calcemia levels. Resumo O hiperparatiroidismo primário é umdistúrbio endócrino caraterizado pela elevação do cálcio sérico associada a níveis de paratormona elevados ou inapropriadamente normais. O diagnóstico é baseado em análises bioquímicas, e, na gravidez, o exame de imagem de primeira linha é a ecografia cervical. É uma doença rara na gravidez, e pode se apresentar com complicações ameaçadoras de vida, pelo que o seu diagnóstico é desafiante. O tratamento médico disponível é limitado, havendo poucos dados relativos à sua eficácia e segurança na gravidez. A cirurgia é o único tratamento curativo, e pode ser realizada no segundo ou terceiro trimestres. Tem sido descrita uma relação entre hiperparatiroidismo primário e pré-eclâmpsia. Apresenta-se um caso de uma grávida de 27 semanas com pré-eclâmpsia com critérios de gravidade, o que obrigou ao término da gravidez por cesariana. Verificou-se agravamento clínico no período pós-parto, com aparecimento de complicações graves, tais como hipercalcemia grave e pancreatite aguda. Ecograficamente, constataram-se duas massas paratiróideias sugestivas de adenomas da paratiroide. A doente recebeu tratamento médico, e teve melhora apenas após a correção dos níveis de cálcio sérico.

Background: Persistent hyperparathyroidism post-transplant is associated with increases in the incidence of cardiovascular events, fractures, and deaths. The aim of this study was to compare both therapeutic options available: parathyroidectomy (PTX) and the calcimimetic agent cinacalcet. Methods: A single center retrospective study including adult renal transplant recipients who developed hypercalcemia due to persistent hyperparathyroidism. Inclusion criteria: PTH > 65 pg/mL with serum calcium > 11.5 mg/dL at any time after transplant or serum calcium persistently higher than 10.2 mg/dL one year after transplant. Patients treated with cinacalcet (n=46) were compared to patients treated with parathyroidectomy (n=30). Follow-up period was one year. Clinical and laboratory data were analyzed to compare efficacy and safety of both therapeutic modalities. Results: PTX controlled calcemia faster (month 1 x month 6) and reached significantly lower levels at month 12 (9.1±1.2 vs 9.7±0.8 mg/dL, p < 0.05); PTX patients showed significantly higher levels of serum phosphate (3.8±1.0 vs 2.9±0.5 mg/dL, p < 0.05) and returned PTH to normal levels (45±51 pg/mL). Cinacalcet, despite controlling calcium and phosphate in the long term, decreased but did not correct PTH (197±97 pg/mL). The proportion of patients that remained with PTH above normal range was 95% in the cinacalcet group and 22% in the PTX group. Patients treated with cinacalcet had better renal function (creatinine 1.2±0.3 vs 1.7±0.7 mg/dL, p < 0.05). Conclusions: Surgical treatment was superior to cinacalcet to correct the metabolic disorders of hyperparathyroidism despite being associated with worse renal function in the long term. Cinacalcet proved to be a safe and well tolerated drug. RESUMO Introdução: O hiperparatireoidismo persistente pós-transplante está associado a aumento na incidência de eventos cardiovasculares, fraturas e óbitos. O objetivo deste estudo foi comparar as opções terapêuticas disponíveis: paratireoidectomia (PTX) e o agente calcimimético cinacalcete. Métodos: Estudo retrospectivo de um único centro incluiu pacientes transplantados renais adultos que desenvolveram hipercalcemia devido a hiperparatireoidismo persistente. Critérios de inclusão: PTH > 65 pg/mL com cálcio sérico > 11,5 mg/dL a qualquer momento após o transplante, ou cálcio sérico persistentemente superior a 10,2 mg/dL um ano após o transplante. Os pacientes tratados com cinacalcete (n = 46) foram comparados aos pacientes tratados com paratireoidectomia (n = 30). O período de acompanhamento foi de um ano. Dados clínicos e laboratoriais foram analisados para comparar a eficácia e a segurança de ambas as modalidades terapêuticas. Resultados: a PTX controlou a calcemia mais rapidamente (mês 1 x mês 6) e atingiu níveis significativamente mais baixos no mês 12 (9,1 ± 1,2 v.s. 9,7 ± 0,8 mg/dL, p < 0,05); pacientes submetidos à PTX apresentaram níveis significativamente mais altos de fósforo sérico (3,8 ± 1,0 v.s. 2,9 ± 0,5 mg/dL, p < 0,05) e retornaram aos níveis normais de PTH (45 ± 51 pg/mL). O cinacalcete, apesar de controlar o cálcio e o fósforo no longo prazo, diminuiu, mas não corrigiu o PTH (197 ± 97 pg/mL). A proporção de pacientes que permaneceram com PTH acima da faixa normal foi de 95% no grupo cinacalcete e 22% no grupo PTX. Os pacientes tratados com cinacalcete apresentaram melhor função renal (creatinina 1,2 ± 0,3 v.s. 1,7 ± 0,7 mg/dL, p < 0,05). Conclusões: O tratamento cirúrgico foi superior ao cinacalcete para corrigir os distúrbios metabólicos do hiperparatireoidismo, apesar de estar associado a pior função renal no longo prazo. Cinacalcete provou ser um medicamento seguro e bem tolerado.

Os principais órgãos acometidos são os rins e os ossos, no entanto, também pode afetar os sistemas cardiovascular e neurológico. Objetivo: Avaliar retrospectivamente os pacientes submetidos a paratireoidectomia para tratamento de hiperparatireoidismo primário no Hospital das Clínicas da Faculdade de Medicina de Botucatu, no período de 1999 a 2019 e elaborar um protocolo para abordagem dos referidos casos. Casuística e Método: Foram avaliados 47 pacientes submetidos a paratireoidectomia neste serviço e que fizeram o acompanhamento pré e pós-operatório em nosso ambulatório. Realizou-se um estudo coorte com avaliação dos dados epidemiológicos a partir de prontuários. Resultados: 38 (80,5%) eram do sexo feminino e a média das idades foi de 60 anos. Em relação aos sinais e sintomas apresentados, 25 pacientes (54,3%) apresentavam queixas renais, 19 (41,3%) tinham história de litíase renal. Vinte e seis pacientes (56,5%) relatavam sintomas ósseos e 32 (73,7%) tinham alteração na densitometria óssea. Treze pacientes (27,65%) não apresentavam qualquer sintoma. Dez pacientes (21,7%) tiveram ultrassonografia positiva e em 36 (81,8%) a cintilografia detectou a glândula doente. Trinta pacientes (66,7%) apresentaram adenoma, seguidos por hiperplasia (23,3%) e carcinoma (8,9%). A comparação entre os exames pré e pós-operatórios mostrou significância nos valores do cálcio, fósforo, albumina e PTH. Observamos, quando comparados com os resultado do anatomopatológico, que nos casos de carcinoma e hiperplasia houve significância para os valores do cálcio e PTH. Conclusão: A paratireoidectomia é um procedimento seguro para o tratamento do hiperparatireoidismo primário com elevadas taxas de sucesso e baixa incidência de complicações. A normalização dos níveis de PTH, cálcio e fósforo, que possibilita a diminuição da agressão osteoarticular e renal, confirma a efetividade da cirurgia no tratamento do hiperparatireoidismo primário. A cintilografia de paratireoides permite identificar a glândula doente na maioria dos adenomas. Introduction: Primary hyperparathyroidism is characterized by an increase in the levels of parathyroid hormone (PTH) in the blood, which generates an imbalance in calcium homeostasis due to the hyperfunction of one or more parathyroid glands. The main organs affected are the kidneys and the bones, however, can also affect the cardiovascular and neurological systems. Objective: A retrospectively assess patients was undergoing parathyroidectomy for the treatment of primary hyperparathyroidism at the Hospital das Clínicas of the Faculty of Medicine of Botucatu, from 1999 to 2019, and to develop a protocol to address these cases. Casuistry and Method: 47 patients who underwent parathyroidectomy in this service and underwent pre and postoperative follow-up were evaluated. A cohort study was conducted with the evaluation of epidemiological data from medical records. Results: 38 (80.5%) were female and the average age was 60 years. When regarded the signs and symptoms presented, 25 patients (54.3%) had renal complaints, 19 (41.3%) had a history of renal lithiasis. Twenty-six patients (56.5%) reported bone symptoms and 32 (73.7%) had changes in bone densitometry. Thirteen patients (27.65%) had no symptoms. Ten patients (21.7%) had positive ultrasonography and in 36 (81.8%) scintigraphy detected the diseased gland. Thirty patients (66.7%) had adenoma, followed by hyperplasia (23.3%) and carcinoma (8.9%). The comparison between pre and postoperative exams showed significance in the values of calcium, phosphorus, albumin and PTH. We observed when compared with the results of the histopathological study that in the cases of carcinoma and hyperplasia, there was significance for the values of calcium and PTH. Conclusion: Parathyroidectomy is a safe procedure for the treatment of primary hyperparathyroidism with high success rates and low incidence of complications. The normalization of levels and PTH, calcium and phosphorus allow the reduction of osteoarticular and renal aggression confirm the effectiveness of surgery in the treatment of primary hyperparathyroidism. Parathyroid scintigraphy makes it possible to identify the diseased gland in most adenomas.

Resumen Existen numerosas causas de hipercalcemia que exigen un amplio diagnóstico diferencial, entre las que se encuentra el adenoma paratiroideo, una etiología rara en la edad pediátrica. El adenoma paratiroideo produce un incremento de hormona paratiroidea (PTH) que desencadena hipercalcemia mediante aumento de la absorción gastrointestinal y tubular renal de calcio, y mayor resorción ósea. El tratamiento inicial tiene como objetivo reducir la calcemia y el tratamiento definitivo consiste en la exéresis quirúrgica del adenoma, ayudada de monitorización de niveles intraoperatorios de PTH. Se presenta el caso de una paciente de diez años, con hallazgo de hipercalcemia en un estudio de dolor abdominal de larga evolución, que en los últimos días asociaba vómitos, anorexia, poliuria y polidipsia. Se trata de un hiperparatiroidismo debido a un adenoma paratiroideo en el que fue necesario utilizar todos los escalones terapéuticos de la hipercalcemia, concluyendo finalmente con la exéresis quirúrgica del adenoma.

Parathyroid adenoma produces an increase in parathyroid hormone (PTH) that triggers hypercalcemia by increasing gastrointestinal and tubular calcium absorption and increased bone resorption. The initial treatment aims to reduce the calcemia and the definitive treatment consists in the surgical excision of the adenoma, aided of monitoring of intraoperative levels of PTH. We present the case of a 10-year-old patient with a finding of hypercalcemia in the study of abdominal pain of long evolution, which associated vomiting, anorexia, polyuria and polydipsia. It is a hyperparathyroidism due to a parathyroid adenoma in which it was necessary to use all the therapeutic steps of hypercalcemia finally concluding with surgical excision of the adenoma.

Relato de caso (Dra. Letícia Luz): Uma mulher branca, 45 anos, branca, veio ao HCPA em 16/10/02 com queixa de dor abdominal difusa, dores no corpo, constipação e ausência de diurese há 24 horas. Tinha estado internada recentemente em outro hospital por hemiparesia direita. Tinha história de hipertensão arterial sistêmica e vinha em uso de captopril, AAS, ibuprofeno e óleo mineral. Ao exame: TA= 160/100 mm Hg; FC= 133 bpm; FR= 30 mpm; Sat O2‚ 97% ; temperatura axilar= 36,7 °C. Apresentava fácies de dor. O abdômen tinha ruídos hidroaéreos positivos, estava levemente distendido e a paciente referia dor à sua palpação, identificando-se massa palpável na região supra-pública. O toque retal mostrou fecaloma. Foram drenados 500 mL de urina, por sondagem vesical. Na ecografia abdominal, o fígado estava aumentado, com lesões heterogêneas, a maior com 12,8 X 9,8 cm., sem plano de clivagem entre a lesão hepática e o rim direito; pequena quantidade de líquido livre na pelve. O exame radiológico de tórax (RX) mostrou elevação da hemicúpula diafragmática direita e imagem nodular densa na base pulmonar direita. RX de abdômen agudo mostrou cólon e retossigmóide preenchido por fezes e alguns níveis hidroaéreos em alças de intestino delgado.No dia 17/10, a paciente apresentou estado confusional. Ao exame, identificou-se, a palpação abdominal, massa pétrea em hipocôndrio D e epigástrio. O exame neurológico mostrou plegia do membro superior direita (MSD) e Babinski bilateral. A tomografia do crânio mostrou aumento de partes moles junto à calvária, que determinava alteração óssea associada, e numerosas áreas de rarefação óssea na alta convexidade. No dia 18/10, foram iniciados hidratação parenteral e pamidronato EV, com melhora parcial da confusão mental. No dia 19/10, a paciente persistia com plegia do MSD, identificando-se também perda acentuada da força em membro inferior esquerdo e arreflexia em membros inferiores. Foi iniciado dexametasona EV. A tomografia mostrou, ao nível da porção lateral direita do canal modular em C5 e C6, material hiperdenso de formato semilunar, presumivelmente extradural. Mostrou também lesões nas asas laterais direitas de C4 e C6. No dia 20/02, houve piora do estado confusional. No dia 21/10, foi realizada laminectomia em C5-C6, com a retirada de lesão espessa, sólida, brancacenta, pouco vascularizada à direita do saco dural. Iniciado ampicilina-sulbactam EV.No dia 22/10, a paciente apresentou oligúria, sendo iniciados hidratação, alopurinol e furosemide. Em 23/10, a paciente evoluiu com insuficiência renal aguda não oligúrica e acidose metabólica, sendo admitida na unidade tratamento intensivo. Permanecia com sinais vitais estáveis. Em 24/10, a paciente evoluiu com piora da acidose, recebendo bicarbonato. Foi iniciada ventilação mecânica. O RX de tórax mostrou extenso derrame pleural à D, o qual foi puncionado. Após, apresentou hipotensão arterial e oligúria, evoluindo a óbito na manhã do dia 25/10.

Cosmetic injections of fillers are common plastic surgery procedures worldwide. Polymethylmethacrylate (PMMA) is a filler approved only for minimally invasive procedures in facial tissue and is among the most frequently used injectable substances for cosmetic purposes. Injection of a large volume of PMMA may lead to the development of severe hypercalcemia and chronic kidney damage in a probably underestimated frequency. In such cases, hypercalcemia develops due to a granulomatous foreign body reaction with extrarenal production of calcitriol. In the present report, we describe the cases of two patients who received injections of large volumes of PMMA and developed severe hypercalcemia and advanced chronic kidney disease. These reports highlight the importance of adhering to regulations regarding the use of PMMA and properly informing patients of the possibility of complications before undertaking such procedures. Resumo Injeções de preenchimento de caráter estético são procedimentos comuns em cirurgia plástica em todo o mundo. O polimetilmetacrilato (PMMA) é um material de preenchimento aprovado apenas para procedimentos minimamente invasivos no tecido facial, e está entre as substâncias injetáveis mais frequentemente usadas para fins estéticos. A injeção de um grande volume de PMMA pode levar ao desenvolvimento de hipercalcemia grave e lesão renal crônica em uma frequência provavelmente subestimada. Nesses casos, a hipercalcemia se desenvolve devido a uma reação granulomatosa de corpo estranho, secundária à produção extrarenal de calcitriol. No presente artigo, descrevemos os casos de dois pacientes que receberam injeções de grandes volumes de PMMA e desenvolveram hipercalcemia grave e doença renal crônica avançada. Esses relatos destacam a importância de seguir as regulamentações sobre o uso do PMMA e informar adequadamente os pacientes sobre a possibilidade de complicações antes de realizar tais procedimentos.

A administração de lítio é uma alternativa terapêutica indicada, comumente, no tratamento de episódios maníacos nos transtornos afetivos bipolares, podendo causar severos danos à função renal do paciente em terapia de longo termo, desencadeando o surgimento e desenvolvimento de doenças como a diabetes insipidus nefrogênica e, mais raramente, o estágio final de doença renal crônica (ESRD). Sabe-se que a ESRD pode ser prevenida e os danos renais estagnados se a terapia de lítio for interrompida com antecedência, posto que após a retirada do lítio, a diabetes insipidus nefrogênica permanece apenas em alguns poucos pacientes.

RESUMEN: Antecedentes: La hipercalcemia maligna es la complicación más frecuente en los pacientes oncológicos, sin embargo, en la población colombiana no hay una descripción publicada sobre las características clínicas de los pacientes con hipercalcemia maligna. Objetivo: Determinar las características clínicas, paraclínicas y terapéuticas de la hipercalcemia maligna en un hospital de alta complejidad en Medellín – Colombia. Métodos: Estudio descriptivo de una cohorte retrospectiva del Hospital San Vicente Fundación entre enero de 2011 y agosto de 2018. La muestra fue seleccionada por conveniencia para los pacientes con hipercalcemia maligna de ese período. Se incluyeron variables demográficas, clínicas y paraclínicas de cada paciente. Resultados: Se incluyeron 70 pacientes. La edad media fue de 60,7 años (Desviación Estándar, DE 15,3). Las neoplasias más frecuentes asociadas a la hipercalcemia de la malignidad fueron el cáncer de pulmón (21.4%), el linfoma (20%) y el mieloma múltiple (14,3%). La mediana de calcio inicial fue de 13,2 mg/dL y la de hormona paratiroidea (PTH) fue de 8,3 pg/mL. Las manifestaciones clínicas más frecuentes fueron neurológicas (91,4%), síntomas generales (88,6%), musculoesqueléticas (81,4%) y gastrointestinales (74,3%). La mortalidad intrahospitalaria fue del 35,7%. Conclusión: En una cohorte en Medellín- Colombia la hipercalcemia maligna se asoció principalmente a cáncer de pulmón, linfoma y mieloma múltiple, las manifestaciones neurológicas fueron su presentación más frecuente y fue un marcador de pobre pronóstico ABSTRACT: Background: Malignancy-associated hypercalcemia is the most frequent complication in cancer patients, however, in the Colombian population there is not a published description about the clinical characteristics of patients with cancer-related hypercalcemia. Objective: To determine the clinical, paraclinical and therapeutic characteristics of malignancy-associated hypercalcemia in a high complexity hospital in Medellín – Colombia. Methods: Descriptive study of a retrospective cohort of the Hospital San Vicente Fundación between January 2011 and August 2018. A convenience sample was taken for the patients with cancer-related hypercalcemia of that period. Demographic, clinical and paraclinical variables of each patient were included. Results: 70 patients were included. The mean age was 60.7 years old (SD 15,3). The most frequent malignancies in cancer-related hypercalcemia were lung cancer (21.4%), lymphoma (20%) and multiple myeloma (14.3%). The median initial calcium was 13.2 mg / dL and parathyroid hormone (PTH) was 8.3 pg/mL. The most frequent clinical manifestations were neurological (91.4%), general symptoms (88.6%), musculoskeletal (81.4%) and gastrointestinal (74.3%). In-hospital mortality was 35.7%. Conclusion: In a cohort in Medellín-Colombia, cancer-related hypercalcemia was mainly associated with lung cancer, lymphoma and multiple myeloma, neurological manifestations were its most frequent presentation and it was a marker of poor prognosis

O pamidronato dissódico, bifosfonato utilizado no tratamento de diversas condições, como hipercalcemia oncogênica, osteoporose e Doença de Paget, pode alterar a biodistribuição do MDP-99m Tc na cintilografia óssea. Relata-se um caso de importante redução da fixação óssea e aumento da captação em partes moles e pulmões em paciente neoplásico com metástases ósseas e hipercalcemia oncogênica tratado recentemente com pamidronato intravenoso. O provável mecanismo responsável pela alteração descrita seria a competição do MDP pelo mesmo sítio de ligação do pamidronato nos cristais de hidroxiapatita. Já o acúmulo do radiotraçador nos pulmões pode ser atribuído à provável formação de microcalcificações decorrente da hipercalcemia apresentada pelo paciente. Vale ressaltar, portanto, a importância do conhecimento dessas possíveis alterações pelos especialistas em medicina nuclear, a fim de se evitar erros diagnósticos.

Primary hyperparathyroidism (PHPT) is characterized by the autonomous production of parathyroid hormone (PTH), in which there is hypercalcemia or normal-high serum calcium levels in the presence of elevated or inappropriately normal serum PTH concentrations. Exceptionally in symptomatic patients, a diagnosis can be established on the basis of clinical data. PHPT must always be evaluated in patients with clinical histories of nephrolithiasis, nephrocalcinosis, osseous pain, subperiosteal resorption, and pathologic fractures, as well as in those with osteoporosis-osteopenia, a personal history of neck irradiation, or a family history of multiple endocrine neoplasia syndrome (types 1 or 2). Diagnosis of PHPT is biochemical. Asymptomatic hypercalcemia without guiding signs or symptoms is the most frequent manifestation of the disease. For differential diagnosis, PTH must be measured, as well as phosphate, chloride, 25-hydroxyvitamin D, 1,25 dyhidroxyvitamin D and calcium-to-creatinine clearance. The diagnosis and differential diagnosis of primary hyperparathyroidism will be discussed here. [ABSTRACT FROM AUTHOR]

The endocrine or humoral paraneoplastic síndromes can be defined as clinical entities, caused by a distance effect of a tumor, independiently of the local effect of its metastases, thath ocurrs mediated by the ectopical production of hormonal peptides o their precursors, citokines and rarely by tiroid hormone or D vitamin. The endocrine paraneoplastic syndromes, are important clinic entities associated to many kind of tumors. The importance of the knowledge of this syndromes is the chance to make a early diagnostic of a previously undiagnosed oncologic entity, avoid the diagnostic mistake induced by this syndromes that can be the predominant clinical scenario, or can be useful for monitoring the evolution and response to the treatment of the neoplasm that originate them. In this review are considerated the next paraneoplastic syndromes: the inappropriate secretion of the antidiuretic hormone, the malignancy's hypercalcemia, hypoglycaemia, Cushing syndrome and acromegaly.

Primary hyperparathyroidism is caused by unique adenoma in 85% of cases; it should be suspected on detecting high blood calcium levels. Prevalence is extremely low in persons under 50 years. High-resolution ultrasound is the imaging mode of choice for diagnostic evaluation. We present the case of a woman 31 years of age in week 20 of pregnancy, with sudden onset primary hyperparathyroidism due to a giant parathyroid adenoma identified during ultrasound exploration of the neck. The patient initially presented neuromuscular values with accelerated deterioration which led to coma. The patient was admitted due to acute pancreatitis associated with hypercalcemic crisis, which was resolved with surgical resection of the tumor. At follow-up she was asymptomatic. Clinical evolution, diagnosis, and treatment are discussed. [ABSTRACT FROM AUTHOR]

ResumenIntroducciónEl cáncer de paratiroides es poco frecuente. Suele presentarse como hiperparatiroidismo primario, en ocasiones como crisis hipercalcémica, con malestar general, náuseas, vómitos, alteraciones del ánimo y pérdida de peso. En algunos casos se presenta como osteítis fibrosa quística, osteopenia difusa, osteoporosis y fracturas patológicas. El diagnóstico suele estar dado por biopsia quirúrgica que muestra invasión a estructuras adyacentes, o metástasis locales y distantes. El tratamiento es la resección quirúrgica del tumor, sin uso de terapias adyuvantes. Su tasa de recurrencia es alta, de 25 a 100%. Algunos factores de mal pronóstico son metástasis a linfonodos en la presentación inicial, metástasis distantes y carcinomas no funcionantes.Caso clínicoPaciente masculino de 64 años que consultó por compromiso del estado general, bradipsiquia, poliuria, cefalea y masa cervical. Además presentaba hipercalcemia y gran elevación de PTH. Se realizó resección quirúrgica de la masa cervical, con biopsia rápida con atipias y mitosis 1/10, y de un nódulo hiperplásico tiroideo. Tras esto, sus niveles de PTH disminuyeron, así como también descendieron sus niveles de calcio.DiscusiónLos pacientes que presentan cáncer de paratiroides suelen tener valores más elevados de calcemia y PTH. Para su diagnóstico, no se recomienda usar biopsia por punción, por riesgo de diseminación y por el bajo rendimiento de esta técnica.ConclusiónPese a ser poco frecuente, se debe pensar en cáncer de paratiroides en el contexto de un paciente con hipercalcemia, especialmente si presenta PTH muy elevada. La sospecha clínica de este diagnóstico tiene directa relación con la posibilidad de tratamiento y pronóstico de la enfermedad.AbstractIntroductionParathyroid cancer is rare. Usually presented as primary hyperparathyroidism, sometimes as hypercalcemic crisis, with general malaise, nausea, vomiting, mood disturbances and low weight. In some cases it occurs as osteitis fibrosa cystica, diffuse osteopenia, osteoporosis and pathological fractures. The diagnosis is usually made by surgical biopsy shows invasion of adjacent structures, or local and distant metastases. The treatment is surgical resection of the tumor, without the use of adjuvant therapies. Their recurrence rate is high, 25 to 100%. Poor prognostic factors are lymph node metastases at initial presentation, distant metastases and nonfunctional carcinomas.Case reportMale patient consulted for 64 years in general conditions, bradypsychia, polyuria, headache and neck mass. He also had hypercalcemia and high elevation of PTH. Surgical resection of the cervical mass was performed, with rapid biopsy atypia and mitosis 1/10, and hyperplastic thyroid nodule. After this, PTH decreased levels as well as levels of calcium.DiscussionPatients with parathyroid cancer tend to have higher serum calcium and PTH of values. For diagnosis, it is not recommended to use needle biopsy, risk of spread and the poor performance of this technique.ConclusionDespite being rare, you should think parathyroid cancer in the context of a patient with hypercalcemia, especially if you have very high PTH. The clinical suspicion of this diagnosis is directly related to the possibility of treatment and prognosis of the disease.

tBackground: Despite well-documented risks, injectable supplements containing high dosesof vitamins are commonly used.Objectives: To describe acute kidney injury (AKI) as a complication of vitamin intoxication.Methods: Our series consisted of 16 patients with kidney complications resulting from theuse of veterinary intramuscular injection supplements of vitamin A, D and E. The patientswere admitted to two referral hospitals in Fortaleza (Brazil) between January 2010 and Jan-uary 2015.Results: Patients’ mean age was 28.3 ± 8.9 years (19–53 years), and 11 (68.7%) were male.Main signs and symptoms upon admission were nausea (68.7%), vomiting (62.5%), weightloss (43.7%), epigastric pain (31.2%) and headache (31.2%). At hospital admission the meanlaboratory values were: hemoglobin 10 ± 2.0 g/dL (6.1–14.2), leukocytes 10,542 ± 4871/mm3(4100–15,100), creatinine 3.9 ± 5.2 mg/dL (0.7–22) and urea 91 ± 88 mg/dL (22–306), respec-tively. Serum calcium was 12 ± 2.2 mg/dL (8.8–15.5), 24-h urine calcium was 575 ± 329 mg(10.7–1058), serum PTH was 55 ± 141 pg/mL (2–406), and serum vitamin D concentration was135 ± 75 ng/mL (22–265). Using KDIGO criteria, AKI was diagnosed in 13 patients (81.2%),classified as stage 1 (n = 3), stage 2 (n = 3) or stage 3 (n = 7). No deaths occurred in the studyperiod.Conclusions: Excessive use of veterinary vitamin supplements containing high doses of vita-min A, D and E was associated with AKI. Hypercalcaemia, which was a common finding,appears to be a contributing factor to the development of this type of AKI. Antecedentes: Suplementos inyectables que contienen altas dosis de vitaminas son utilizados con frecuencia, a pesar de los riesgos bien documentados. Objetivo: Describir la ocurrencia de dan˜ o renal agudo (IRA) como complicación de intoxi- cación por suplementos vitamínicos. Métodos: Esta es una serie de 16 pacientes con complicaciones renales resultantes de la utilización de inyección intramuscular de suplementos veterinarios con vitaminas A, D y E. Los pacientes fueron ingresados en 2 hospitales de referencia en Fortaleza (Brasil), entre enero de 2010 y enero de 2015. Resultados: La edad media de los pacientes fue de 28,3 ± 8,9 an˜ os (19–53 an˜ os) y 11 (68,7%) eran varones. Signos y síntomas principales al ingreso fueron náuseas (68,7%), vómitos (62,5%), pérdida de peso (43,7%), dolor epigástrico (31,2%) y cefalea (31,2%). Al ingreso en el hospital los valores medios de laboratorio fueron: hemoglobina 10 ± 2,0 g/dL (6,1–14,2), leucocitos 10.542 ± 4.871/mm3 (4.100–15.100), creatinina 3,9 ± 5,2 mg/dL (0,7–22) y urea 91 ± 88 mg/dL (22–306), respectivamente. El nivel de calcio sérico fue de 12 ± 2,2 mg/dL (8,8–15,5), el de calcio en orina de 24 h fue de 575 ± 329 mg (10,7–1.058), el de PTH sérico fue de 55 ± 141 pg/mL (2–406) y el nivel de vitamina D sérica fue de 135 ± 75 ng/mL (22–265). Utilizando criterios KDIGO, se diagnosticó IRA en 13 pacientes (81,2%); fueron clasificadas como clase 1 (n = 3), clase 2 (n = 3) y clase 3 (n = 7). No hubo muertes en el período de estudio. Conclusiones: El uso excesivo de suplementos vitamínicos veterinarios que contienen altas dosis de vitamina A, D y E se asoció con IRA. La hipercalcemia, un hallazgo común, parece ser un factor que contribuye al desarrollo de este tipo de IRA.

Introduction: Acute lymphoblastic leukemia (ALL) is the most common malignant neoplasm in children and the leading cause of cancer death in this age group. Hypercalcemia associated with frank osteolytic lesions is a rare presentation of ALL. Case Report: 9-year-old male, 37 kg, presented with headache, pain and functional impotence in the lower right leg for 15 days. Laboratory tests showed elevation of erythrocyte sedimentation rate and C-reactive protein with hypercalcemia. Imaging studies revealed bone demineralization and diffuse osteolytic lesions. Bone marrow aspiration showed 10% of blasts, which did not characterize leukemia. Due to the improvement of his clinical condition, the patient continued the clinical investigation as an outpatient. Biopsy of lytic lesion in the hip and new bone marrow aspirations detected higher number of blasts and confirmed the diagnosis of ALL. Treatment was initiated, following the protocol of the Brazilian Group of Treatment of Leukemia in Childhood, 2009. After two years, he was well and without disease. Conclusion: Hypercalcemia is associated with only 0.6% to 4.8% of all ALL cases. The patient presented only diffuse bone pain and hypercalcemia, without the usual symptoms, which makes his clinical condition even rarer, with such presentation being very scarce in the literature. Although uncommon, hypercalcemia and diffuse osteolytic lesions may be the first and only manifestations of ALL in the pediatric range. The present report is important in helping to formulate early diagnosis of childhood leukemia, even in the presence of an atypical clinical condition. Introducción: La leucemia linfoblástica aguda (LLA) es la neoplasia maligna más común en los niños y principal causa de muerte por cáncer en ese grupo de edad. La hipercalcemia asociada a lesiones osteolíticas francas es una rara presentación de LLA. Relato del Caso: Paciente de 9 años, masculino, 37kg, presentaba cefalea, dolor e impotencia funcional en miembro inferior derecho hace 15 días. Los exámenes de laboratorio evidenciaron elevación de velocidad de sedimentación globular y proteína C reactiva con hipercalcemia. En los exámenes de imagen, presentaba desmineralización ósea y lesiones osteolíticas difusas. Aspirado de médula ósea (MO) evidenció el 10% de blastos, lo que no caracterizó la leucemia. Debido a la mejora del cuadro clínico, el paciente siguió la investigación diagnóstica ambulatoriamente. La biopsia de lesión lítica en cadera y nuevo aspirado de MO detectaron mayor número de blastos y confirmaron el diagnóstico de LLA. Se inició tratamiento con protocolo del Grupo Brasileño de Tratamiento de Leucemias en la Infancia, 2009. Conclusión: La hipercalcemia está asociada a sólo 0,6% a 4,8% de los casos de LLA. El paciente en cuestión presentaba sólo dolores óseos difusas e hipercalcemia, sin la sintomatología habitual, lo que hace el cuadro clínico del paciente aún más raro, siendo tal presentación muy escasa en la literatura. A pesar de inusual, hipercalcemia y lesiones osteolíticas difusas pueden ser las primeras y únicas manifestaciones de LLA en niños. El presente relato se vuelve importante al ayudar a la formulación de diagnósticos precoces de la leucemia infantil, incluso en la vigencia de un cuadro clínico atípico. Introdução: A leucemia linfoblástica aguda (LLA) é a neoplasia maligna mais comum em crianças e a principal causa de morte por câncer nessa faixa etária. A hipercalcemia associada a lesões osteolíticas francas é uma rara apresentação da LLA. Relato do Caso: Paciente de 9 anos, sexo masculino, 37kg, apresentava cefaleia, dor e impotência funcional em membro inferior direito há 15 dias. Exames laboratoriais evidenciaram elevação de velocidade de hemossedimentação e proteína C reativa com hipercalcemia. Nos exames de imagem, apresentava desmineralização óssea e lesões osteolíticas difusas. Aspirado de medula óssea (MO) evidenciou 10% de blastos, o que não caracterizou leucemia. Pela melhora do quadro clínico, o paciente seguiu com investigação diagnóstica ambulatorialmente. Biópsia de lesão lítica em quadril e novo aspirado de MO detectaram maior número de blastos e confirmaram o diagnóstico de LLA. Iniciou tratamento com protocolo do Grupo Brasileiro de Tratamento de Leucemias na Infância, 2009. Após dois anos, estava bem e sem doença. Conclusão: A hipercalcemia está associada a apenas 0,6% a 4,8% dos casos de LLA. O paciente em questão apresentava apenas dores ósseas difusas e hipercalcemia, sem a sintomatologia habitual, o que torna seu quadro clínico ainda mais raro, sendo tal apresentação muito escassa na literatura. Apesar de incomuns, hipercalcemia e lesões osteolíticas difusas podem ser as primeiras e únicas manifestações de LLA na faixa pediátrica. O presente relato torna-se importante ao auxiliar a formulação de diagnósticos precoces da leucemia infantil, mesmo na vigência de um quadro clínico atípico.

Recién nacidos prematuros; Hipercalcemia; Hipofosfatemia preterm infants; Hypercalcaemia; Hypophosphataemia Nounats prematurs; Hipercalcèmia; Hipofosfatèmia Introduction Aggressive parenteral nutrition with delivery of high amino acid and energy doses is used to improve growth and neurodevelopmental outcomes in very low birth weight (VLBW) preterm infants. Recent findings, however, suggest that this approach may cause electrolyte imbalances. The aim of our study was to compare the prevalence of hypercalcaemia, hypophosphataemia, and hypokalaemia in 2 groups of preterm infants that received parenteral nutrition with different amounts of amino acids and to analyse perinatal and nutritional variables associated with the development of electrolyte imbalances. Methods We conducted a retrospective observational study comparing 2 groups of preterm infants born before 33 weeks’ gestation with birth weights of less than 1500 g managed with parenteral nutrition. One of the groups received less than 3 g/kg/day of amino acids and the other received 3 g/kg//day of amino acids or more. We analysed the prevalence of electrolyte imbalances and possible associations with aggressive parenteral nutrition, adjusting for potential confounders. Results We studied 114 infants: 60 given less than 3 g/kg/day of amino acids (low-intake group) and 54 given at least 3 g/kg/day (high-intake group). The prevalence of electrolyte imbalances was similar in both groups. The prevalence of hypercalcaemia was 1.67% in the low-intake group and 1.85% in the high-intake group (P > .99), the prevalence of severe hypophosphataemia 11.7% vs 9.3%, and the prevalence of hypokalaemia 15.0% vs 11.1% (P > .99). A calcium to phosphorus ratio greater than 1.05 had a protective effect against hypophosphataemia (P = .007). Conclusions We did not find an association between hypercalcaemia, hypophosphataemia, and hypokalaemia and the amino acid dose delivered by PN in the high-intake group of preterm infants. Introducción La nutrición parenteral agresiva con aportes energéticos y proteicos altos se utiliza para mejorar el crecimiento y el neurodesarrollo en recién nacidos prematuros de muy bajo peso. No obstante, hallazgos recientes sugieren que su uso puede ocasionar alteraciones electrolíticas. El objetivo del estudio era comparar la prevalencia de hipercalcemia, hipofosfatemia e hipopotasemia en dos grupos de recién nacidos prematuros que recibieron nutrición parenteral con distintos aportes de aminoácidos, y analizar variables perinatales y nutricionales asociadas a la ocurrencia de alteraciones electrolíticas. Métodos Estudio retrospectivo observacional, con comparación de 2 grupos de recién nacidos prematuros con peso < 1500 g y edad gestacional < 33 semanas manejados con nutrición parenteral. Uno de los grupos recibió < 3 g/kg/d de aminoácidos mientras que el otro recibió ≥3 g/kg/d. Se analizó la prevalencia de distintas alteraciones electrolíticas y su asociación con la nutrición parenteral agresiva, con ajustes para posibles factores de confusión. Resultados El análisis incluyó 114 recién nacidos: 60 que recibieron < 3 g/kg/d de aminoácidos (ingesta baja) y 54 que recibieron ≥ 3 g/kg/d (ingesta alta). La prevalencia de alteraciones electrolíticas fue similar en ambos grupos. La prevalencia de hipercalcemia fue de 1,67% en el grupo de ingesta baja y 1,85% en el grupo de ingesta alta (p > 0,99). Los respectivos valores para las otras alteraciones fueron 11,7% vs. 9,3% en el caso de la hipofosfatemia grave y 15,0% vs. 11,1% en el caso de la hipopotasemia (p > 0,99). Se observó que una relación calcio:fósforo superior a 1,05 ofrecía un efecto protector frente a la hipofosfatemia (p = 0,007). Conclusiones No se observó asociación entre la hipercalcemia, hipofosfatemia o la hipopotasemia y el aporte de aminoácidos mediante nutrición parenteral en la población de recién nacidos prematuros con ingestas altas de aminoácidos.

Antecedentes: La hipercalcemia maligna es la urgencia endocrinológica en cáncer más común y en nuestro país no se ha caracterizado. Los factores relacionados a su presentación no han sido evaluados en la literatura internacional. Objetivo: Determinar los factores asociados a la presentación de Hipercalcemia maligna, en los pacientes que ingresaron al Instituto Nacional de Cancerología en el quinquenio 2014-2019. Materiales y métodos: Estudio analítico de casos y controles, retrospectivo. Población y muestra: Casos: Obtenidos mediante población censal. Para la Fase I, se incluyeron 100 casos de adultos con cáncer y medición de calcio sérico corregido por albúmina mayor o igual a 10.5 mg/dL. Controles: Se incluyeron 100 controles, de pacientes con cáncer y calcio sérico corregido normal (8.5 a 10.4 mg/dL), se usó una proporción similar de pacientes con Carcinoma escamocelular como variable emparejadora. Análisis: Se realizó análisis uni y bivariado. Las asociaciones entre las variables y la presentación de hipercalcemia maligna, se analizaron con el OR crudo que fue ajustado en un análisis multivariado. Aquellas con asociación estadísticamente significativa (p0.05), fueron incluidas en el análisis de regresión logística. Resultados: La mediana de Calcio para los casos y controles fue de 14.7 (13.3-15.9) vs 9.37 (8.93-9.75) (p 0.0001). La mediana de edad fue de 56 y 57 años respectivamente. En los controles fue más frecuente el sexo femenino. En los casos se encontró mayor proporción de metástasis con un 65% vs 42% (p: 0.001). Las variables que demostraron asociación con la presentación de hipercalcemia maligna fueron el sexo femenino OR 0.37 (IC 95% 0.18-0.77), la albúmina OR 0.37(IC 95% 0.21-0.64), índice de karnofsky OR 0.96 (IC95% 0.95-0.98) y presencia de metástasis OR 2.48 (1.21-5.09). El 63% de los casos desarrollo síntomas neurológicos. Los días de estancia hospitalaria tuvieron una mediana de 21 (9-26) para los casos vs 13 (7-17) para los controles (p: 0.0001) y la muerte intrahospitalaria se presentó en el 49% vs 10% (p: 0.0001). Conclusiones: El sexo femenino, los valores de albumina normales y el índice de karnofsky de 70 o más se comportaron como factores protectores asociados a la presentación de hipercalcemia maligna mientras que la presencia de metástasis es un factor de riesgo. Abstract: Background: Malignant hypercalcemia is the most common endocrinological emergency in cancer and in our country it has not been noticed. The factors related to its presentation have not been evaluated in the international literature. Objective: To determine the factors associated with the presentation of malignant hypercalcemia in patients admitted to the National Cancer Institute during the quinquennium 2014-2019. Materials and methods: Retrospective case-control analytical study. Population and sample: Cases: Obtained through census population. For phase I, it includes 100 cases of adults with cancer and measurement of calcium corrected by albumin greater than or equal to 10.5 mg / dL. Controls: 100 controls were included, from patients with cancer and normal corrected serum calcium (8.5 to 10.4 mg / dL), a similar proportion of patients with squamous cell carcinoma was used as a pairing variable. Analysis: A univariate and bivariate analysis was performed. The associations between the variables and the presentation of malignant hypercalcemia are analyzed with the OR that has been adjusted in a multivariate analysis. Those with statistically significant association (p 0.05), were included in the logistic regression analysis. Results: The median calcium for cases and controls was 14.7 (13.3-15.9) vs. 9.37 (8.93-9.75) (p 0.0001). The median age was 56 and 57 years respectively. In the controls the female sex was more frequent. In the cases, a higher proportion of metastases was found with 65% vs 42% (p: 0.001). The variables that demonstrated association with the presentation of malignant hypercalcemia were female sex OR 0.37 (95% CI 0.18-0.77), albumin OR 0.37 (95% CI 0.21-0.64), karnofsky index OR 0.96 (95% CI 0.95-0.98) and presence of metastases OR 2.48 (1.21-5.09). 63% of cases developed neurological symptoms. The days of hospital stay had a median of 21 (9-26) for cases vs 13 (7-17) for controls (p: 0.0001) and in-hospital death occurred in 49% vs. 10% (p: 0.0001). Conclusions: Female sex, normal albumin values and karnofsky index of 70 or more behaved as protective factors associated with the presentation of malignant hypercalcemia while the presence of metastases is a risk factor.

La injuria renal aguda es una entidad clínica compleja, caracterizada por la disminución abrupta de la función renal. La hipercalcemia como etiología de la misma es poco frecuente. Los mecanismos involucrados en su desarrollo son múltiples y poco estudiados. Se presenta el caso de un paciente varón de 59 años que desarrolló un cuadro severo de falla renal aguda como complicación de crisis hipercalcémica por un adenoma de paratiroides. Se observó alteración en los marcadores de daño y función renal. La bioquímica urinaria mostró una necrosis tubular aguda. Los niveles de calcio, parathormona y calciuria se asociaron a endocrinopatía. La ecografía, el centellograma y la biopsia paratiroidea mostraron la presencia de un adenoma. Se presentaron otras complicaciones sistémicas concomitantes como pancreatitis y complicaciones cardíacas. El tratamiento paliativo fue la hemodiálisis y el definitivo la paratiroidectomía. El síndrome de hueso hambriento se presentó como una complicación postquirúrgica. Tras el alta, la recuperación de la función renal nunca fue total. El daño renal agudo asociado a disfunción sistémica por hipercalcemia puede llevar a una recuperación parcial de la función renal. Se debe considerar el desarrollo de enfermedad renal crónica posterior a la falla renal aguda por hipercalcemia como complicación de la misma. Acute renal injury is a complex clinical entity, characterized by the abrupt worsening in renal function. Hypercalcemia as its etiology is rare. The mechanisms involved in its development are multiple and rarely studied. The case of a 59-year-old male patient who developed a severe acute renal failure as a complication of an hypercalcemic crisis due to a parathyroid adenoma is presented here. Alterations in markers of damage and renal function were observed. Urinary biochemistry showed acute tubular necrosis. Calcium, parathormone and urine calcium levels were associated with endocrinopathy. The ultrasound, the scintigraphy and the parathyroid biopsy showed the presence of an adenoma. There were other concomitant systemic complications such as pancreatitis and cardiac complications. Hemodialysis was the palliative treatment, while the definitive treatment was parathyroidectomy. The hungry bone syndrome occurred as a postoperative complication. After discharge, recovery of renal function was never complete. Acute renal damage associated with systemic dysfunction due to hypercalcemia can lead to a partial recovery of renal function. The development of chronic kidney disease after acute renal failure due to hypercalcemia should be considered one of its complications. A Lesão renal aguda é uma entidade clínica complexa, caracterizada pela diminuição abrupta da função renal. A hipercalcemia como etiologia da mesma não é muito frequente. Os mecanismos que participam no seu desenvolvimento são múltiplos e pouco estudados. Apresenta-se o caso de um paciente, homem, de 59 anos, que desenvolveu um quadro severo de insuficiência renal aguda como complicação de crise hipercalcêmica por um adenoma da paratireóide. Foi observada alteração nos marcadores de dano e função renal. A bioquímica urinária mostrou uma necrose tubular aguda. Os níveis de cálcio, paratormona e calciúria foram associados a endocrinopatia. A ultra-sonografia, a cintilografia, e a biópsia da paratireóide mostraram a presença de um adenoma. Apresentaram-se outras complicações sistêmicas concomitantes como pancreatite e cardíacas. O tratamento paliativo foi hemodiálise e o definitivo, a paratireoidectomia. A síndrome do osso faminto apresentou-se como uma complicação pós-operatória. Após a alta, a recuperação da função renal nunca foi total. O dano renal agudo associado à disfunção sistêmica por hipercalcemia pode levar para uma recuperação parcial da função renal. Deve ser considerado o desenvolvimento da doença renal crônica posterior à insuficiência renal aguda por hipercalcemia como complicação da mesma.

RESUMEN La sarcoidosis es una enfermedad inflamatoria sistémica idiopática que afecta principalmente a los pulmones. Las manifestaciones extrapulmonares ocurren aproximadamente en 30% de los pacientes. Los sitios más comunes de enfermedad extrapulmonar incluyen la piel, los globos oculares, el sistema reticuloendotelial, el sistema musculoesquelético, las glándulas exócrinas, el corazón, los riñones y el sistema nervioso central. Presentamos un caso clínico de sarcoidosis con afectación de ganglios linfáticos periféricos, alteración renal y cutánea sin afectación pulmonar el cual representa un desafío diagnóstico por la ausencia de las características típicas de esta patología. ABSTRACT Sarcoidosis is an idiopathic systemic inflammatory disease that mainly affects the lungs. Extrapulmonary manifestations occur in approximately 30% of patients. The most common sites of extrapulmonary disease include the skin, eyeballs, reticuloendothelial system, musculoskeletal system, exocrine glands, heart, kidneys, and central nervous system. We present a clinical case of sarcoidosis with involvement of peripheral lymph nodes, renal and cutaneous alterations without pulmonary involvement, which represents a diagnostic challenge due to the absence of the typical characteristics of this pathology.

Neste artigo, os autores apresentam um caso de uma paciente de 60 anos que procurou um serviço de emergência com quadro de vômitos incoercíveis e que apresentava nos exames de urgência uma hipercalcemia de 19g/dL. Após estabilização do cálcio sérico com hidratação, corticóide e bifosfonatos, a elaboração diagnóstica revelou um linfoma de pequenas células não clivadas, tipo Burkitt, um linfoma não-Hodgkin que raramente tem sido associado a essa apresentação inicial. Os autores fazem, ainda, uma breve revisão da literatura sobre as neoplasias mais comumente associadas à hipercalcemia.

VITAMIN D deficiency , *KIDNEY failure , *HYPERCALCEMIA , *VITAMINS in the blood , *VITAMIN D - Abstract
The association between vitamin D deficiency and increased risk of, among others, cardiovascular and autoimmune diseases has lead in the last years to an enhanced interest in the usage of supplements to achieve the normalization of plasmatic values at 25(OH) D. Apparently this search for normalization is resulting in an higher incidence on vitamin D intoxication. We present the case of an 81 years old woman with metabolic encephalopathy and renal failure secondary to iatrogenic vitamin D intoxication. Calcium and vitamin D oral supplements were prescribed after an osteoporotic vertebral fracture. The patient improved clinically as well as analytically after receiving treatment with diuretics and hydration. We emphasize the importance of discarding hypercalcemia as a cause of metabolic encephalopathy; moreover we highly recommend keeping vitamin D intoxication in mind as an uncommon although always possible etiology of reversible hypercalcemia and renal failure.

ResumoIntroduçãoApesar da associação entre patologia tiroideia e hiperparatiroidismo primário ser frequente, a existência concomitante de hipertiroidismo e hiperparatiroidismo primário é extremamente rara.Descrição do casoDoente do sexo masculino de 46 anos, com antecedentes de litíase renal e gastrite. Referenciado a consulta externa de Endocrinologia por hipertiroidismo subclínico e bócio multinodular (BMN), detetados na sequência de investigação de quadro de perda de peso de 10kg em 2 meses. No exame objetivo destacava‐se tensão arterial (TA) 110/70mmHg, frequência cardíaca (FC) 70bpm, peso 76kg e nódulo elástico com cerca de 3‐4cm ao nível da transição istmo/lobo esquerdo da tiroide. A avaliação laboratorial confirmou o hipertiroidismo subclínico com anticorpos negativos, nomeadamente anticorpos antirrecetores da hormona tíreoestimulante – TSH – (TRAbs), e a cintigrafia tiroideia foi compatível com adenoma de Plummer no lobo esquerdo da tiroide, pelo que o doente foi proposto para terapêutica com iodo radioativo. Contudo, previamente à terapêutica, por lombalgia, realizou osteodensitometria, compatível com osteoporose, e repetiu avaliação laboratorial, que revelou hiperparatiroidismo primário. A cintigrafia com Sestamibi evidenciou hipercaptação ao nível da paratiroide inferior esquerda. Foi então submetido a lobectomia e paratiroidectomia inferior esquerdas, com anatomia patológica compatível com adenoma folicular da tiroide e adenoma de células claras da paratiroide. Atualmente, 4 meses após a cirurgia, encontra‐se sem sinais ou sintomas de alteração do metabolismo fosfocálcico, sob terapêutica com levotiroxina, cálcio e calcitriol.ComentárioO diagnóstico de hipercalcemia nos doentes com hipertiroidismo representa um desafio diagnóstico, uma vez que a sintomatologia é inespecífica e pode confundir‐se, ou ser camuflada pela sintomatologia do hipertiroidismo. Apesar de quase sempre ser secundária ao hipertiroidismo e resolver com a sua correção, deve ser realizado o doseamento da hormona paratiroideia (PTH) nos doentes com hipercalcemia e hipertiroidismo para deteção dos casos de hiperparatiroidismo primário, uma vez que este pode alterar a atitude terapêutica a tomar.AbstractIntroductionAlthough the association between thyroid disease and primary hyperparathyroidism is well recognized, the coexistence of hyperthyroidism and primary hyperparathyroidism is extremely rare.Case report46 year‐old man, with a past history of kidney stones and gastritis. He was referred to the Endocrinology outpatient department due to subclinical hyperthyroidism and multinodular goiter, found during the investigation of a weight loss of 22 pounds in two months. On examination the blood pressure was 110/70mmHg, the heart rate 70bpm and the weight 168 pounds and the thyroid exam revealed an elastic nodule with 3‐4cm in the transition between the left lobe and the isthmus. Laboratory tests confirmed the subclinical hyperthyroidism with negative antibodies, namely the thyrotropin receptor antibodies (TRAbs), and the thyroid scintigraphy revealed a left lobe Plummer adenoma, so the patient was referred to radioiodine therapy. However, and before the treatment was carried out, he complained of back pain. The bone densitometry detected osteoporosis, the blood tests primary hyperparathyroidism and the sestamibi parathyroid scintigraphy a hypercaptation area in the left inferior parathyroid. A left thyroid lobectomy and a left inferior parathyroidectomy were carried out. The histology revealed thyroid follicular adenoma and white clear cell parathyroid adenoma. Four months later, the patient is treated with levothyroxine, calcium and calcitriol and has no signs or symptoms of phospho‐calcium metabolism disfunction.DiscussionThe occurrence of hypercalcemia in a hyperthyroid patient may present a diagnostic problem, since the symptoms are non‐specific or may be masked by the hyperthyroidism symptoms. Although it is almost always secondary to the hyperthyroidism and cure with thyroid function normalization, the parathyroid hormone (PTH) assay must be carried out in hyperthyroid patients with hypercalcemia, because a primary hyperparathyroidism diagnose can probably change the treatment decision.
