ABSTRACT

The compound "ADE" is an injectable oil for veterinary use which contains large amounts of vitamins A, D and E. The parenteral application in humans leads to a granuloma reaction which triggers hypercalcemia. A 42-year-old man was admitted with lower limb pain, nephrolithiasis and nephrocalcinosis. Laboratory tests revealed creatinine 4.59 mg/dl, calcium 13.3 mg/dl and parathormone 13.8 pg/ml. He underwent an ureterolithotripsy, stent placement, intravenous crystalloid fluids, and corticosteroid. He improved symptoms, kidney function and normalized serum calcium. The "ADE"-induced hypercalcemia diagnosis can be challenging. The early diagnosis may avoid negative outcomes.


O composto "ADE'' é um óleo veterinário injetável que contém grandes quantidades de vitaminas A, D e E. A aplicação parenteral causa reação granulomatosa e hipercalcemia. Um homem de 42 anos foi admitido com dor no membro inferior, nódulos musculares endurecidos, nefrolitíase e nefrocalcinose. O laboratório revelou creatinina 4,59 mg/dl, cálcio 13,3 mg/dl e paratormônio 13,8 pg/ml. Foi tratado com ureterolitotripsia, cateter duplo-J, cristaloide intravenoso e corticoterapia. Ele apresentou melhora dos sintomas, função renal e normalizou cálcio. O diagnóstico da hipercalcemia pelo "ADE'' pode ser desafiador. O diagnóstico precoce pode evitar desfechos negativos.

ABSTRACT

Background: hypercalcemia mediated by a silicone-induced granulomatous reaction is a condition that, despite being rare, must be remembered since there is an increasing demand for aesthetic procedures among the general population. It is necessary to rule out other causes of hypercalcemia, such as hyperparathyroidism, hypercalcemia of malignancy, infectious and non-infectious granulomatous diseases, as well as the use of drugs. Case presentation: We present a patient with a history of large amounts of silicone implants who was admitted to a hospital presenting hypercalcemia and chronic kidney disease. A skin biopsy revealed a granulomatous foreign body reaction associated with exogenous siliconomatous material. Treatment with corticosteroids was initiated, with partial renal function improvement, with no renal replacement therapy needed. Conclusion: Patients with silicone implants should be carefully monitored for renal function and may be informed to avoid nephrotoxic agents as there is sufficient evidence that this type of aesthetic procedure can trigger hypercalcemia and CKD.


Introdução: a hipercalcemia mediada por uma reação granulomatosa induzida por silicone é uma condição que, apesar de rara, deve ser lembrada, pois há uma demanda crescente por procedimentos estéticos na população em geral. É necessário descartar outras causas de hipercalcemia, como hiperparatireoidismo, hipercalcemia da malignidade, doenças granulomatosas infecciosas e não infecciosas, bem como o uso de medicamentos. Relato de caso: apresentamos um paciente com histórico implante de grandes quantidades de silicone, que foi admitido em um hospital apresentando hipercalcemia e doença renal crônica (DRC). A biópsia de pele revelou reação granulomatosa tipo corpo estranho associada a material siliconomatoso exógeno. Foi iniciado tratamento com corticosteroides, com melhora parcial da função renal, sem necessidade de terapia renal substitutiva. Conclusão: os pacientes com implantes de silicone devem ser cuidadosamente monitorados quanto à função renal e devem ser informados para evitar agentes nefrotóxicos, pois há evidências suficientes de que esse tipo de procedimento estético pode desencadear hipercalcemia e DRC.

ABSTRACT

Introducción: describir el caso de un paciente con pancreatitis aguda secundaria a hipercalcemia por hiperparatiroidismo prImario. Esta es una causa poco frecuente de pancreatitis, asociada a morbimortalidad significativa en caso de no ser diagnosticada oportunamente Caso clínico: un hombre de 44 años, con antecedente de pancreatitis de presunto origen biliar que había requerido previamente colecistectomía, consultó por dolor abdominal y náuseas. Los estudios complementarios fueron compatibles con un nuevo episodio de pancreatitis aguda. Presentaba hipercalcemia y hormona paratiroidea (PTH) elevada, configurando hiperparatiroidismo primario. La gammagrafía informó hallazgos compatibles con adenoma paratiroideo. Se inició tratamiento con reanimación hídrica y analgesia con adecuada disminución de calcio sérico y resolución de dolor abdominal. Después de la paratiroidectomía se logró normalizar los niveles de calcio y PTH. Discusión: la pancreatitis aguda es una condición potencialmente fatal, por lo que la sospecha de causas poco frecuentes como la hipercalcemia debe tenerse en cuenta. El tratamiento de la hipercalcemia por adenoma paratiroideo se basa en reanimación hídrica adecuada y manejo quirúrgico del adenoma, con el fin de evitar recurrencia de pancreatitis y mortalidad. (AU)


Introduction: we describe the case of a patient with acute pancreatitis secondary to hypercalcemia due to primary hyperparathyroidism. This is a rare cause of pancreatitis associated with significant morbidity and mortality if not diagnosed in time. Clinical case: a 44-year-old man with a history of pancreatitis of presumed biliary origin, which had previously required cholecystectomy, consulted for abdominal pain and nausea. The laboratory findings were compatible with a new episode of acute pancreatitis. He presented hypercalcemia and an elevated parathyroid hormone (PTH), configuring primary hyperparathyroidism. Scintigraphy was performed, yielding findings compatible with parathyroid adenoma. Treatment with fluid resuscitation and analgesia was started, resulting in an adequate decrease in serum calcium and resolution of abdominal pain. After parathyroidectomy, calcium and PTH levels were normalized. Discussion: acute pancreatitis is a potentially fatal condition; therefore the suspicion of rare causes, such as hypercalcemia, should be considered. The treatment of hypercalcemia due to parathyroid adenoma is based on adequate fluid resuscitation and surgical management of the adenoma, to avoid recurrence of pancreatitis and death. (AU)

ABSTRACT

@#Primary hyperparathyroidism commonly affects elderly women. When present in the young population, it is usually asymptomatic, most frequently due to a parathyroid adenoma and the definitive management is surgical excision. Uncommonly, 5-10% of patients fail to achieve long-term cure after initial parathyroidectomy and 6-16% of them is due to an ectopic parathyroid adenoma that will require focused diagnostic and surgical approaches. We report a 21-year-old male who had bilateral thigh pain. Work-up revealed bilateral femoral fractures, brown tumors on the arms and multiple lytic lesions on the skull. Serum studies showed hypercalcemia (1.83 mmol/L), elevated parathyroid hormone [(PTH) 2025.10 pg/mL], elevated alkaline phosphatase (830 U/L), normal phosphorus (0.92 mmol/L) and low vitamin D levels (18.50 ng/mL). Bone densitometry showed osteoporotic findings. Sestamibi scan showed uptake on the left superior mediastinal region consistent with an ectopic parathyroid adenoma. Vitamin D supplementation was started pre-operatively. Patient underwent parathyroidectomy with neck exploration; however, the pathologic adenoma was not visualized and PTH levels remained elevated post-operatively. Chest computed tomography with intravenous contrast was performed revealing a mediastinal location of the adenoma. A repeat parathyroidectomy was done, with successful identification of the adenoma resulting in a significant drop in PTH and calcium levels. Patient experienced hungry bone syndrome post-operatively and was managed with calcium and magnesium supplementation. A high index of suspicion for an ectopic adenoma is warranted for patients presenting with hypercalcemia and secondary osteoporosis if there is persistent PTH elevation after initial surgical intervention. Adequate follow-up and monitoring is also needed starting immediately in the post-operative period to manage possible complications such as hungry bone syndrome.

ABSTRACT

Objective: To investigate the causative factors of renal function in newly diagnosed multiple myeloma (MM) patients with renal inadequacy. Methods: 181 MM patients with renal impairment from August 2007 to October 2021 at Peking Union Medical College Hospital were recruited, whose baseline chronic kidney disease (CKD) stage was 3-5. Statistical analysis was performed based on laboratory tests, treatment regimens, hematological responses, and survival among various renal function efficacy groups. A logistic regression model was employed in multivariate analysis. Results: A total of 181 patients were recruited, and 277 patients with CKD stages 1-2 were chosen as controls. The majority choose the BCD and VRD regimens. The progression-free survival (PFS) (14.0 months vs 24.8 months, P<0.001) and overall survival (OS) (49.2 months vs 79.7 months, P<0.001) of patients with renal impairment was considerably shorter. Hypercalcemia (P=0.013, OR=5.654) , 1q21 amplification (P=0.018, OR=2.876) , and hematological response over a partial response (P=0.001, OR=4.999) were independent predictive factors for renal function response. After treatment, those with improvement in renal function had a longer PFS than those without (15.6 months vs 10.2 months, P=0.074) , but there was no disparity in OS (56.5 months vs 47.3 months, P=0.665) . Conclusion: Hypercalcemia, 1q21 amplification, and hematologic response were independent predictors of the response of renal function in NDMM patients with renal impairment. MM patients with CKD 3-5 at baseline still have worse survival. Improvement in renal function after treatment is attributed to the improvement in PFS.

ABSTRACT

A leucemia de células plasmocitárias (LCP) é uma neoplasia hematológica rara, de caráter agressivo, ainda sem consenso quanto ao melhor esquema terapêutico e prognóstico da doença. Alguns estudos a consideram como uma variante do mieloma múltiplo. O objetivo deste estudo foi realizar um relato de caso e desenvolver uma revisão sistemática da literatura sobre os fatores prognósticos relacionados a essa enfermidade. Esta revisão sistemática seguiu o protocolo PRISMA, utilizou o PubMED como base de dados, buscando estudos que avaliassem fatores prognósticos da LCP. Os estudos selecionados foram posteriormente avaliados quanto a sua qualidade pelo protocolo STROBE. A primeira busca identificou 260 artigos. Após aplicado critério de exclusão, dez foram selecionados. Destes, oito avaliaram fatores prognósticos clínicos e laboratoriais; cinco avaliaram, além disso, fatores citogenéticos; e um avaliou apenas a idade como fator prognóstico. A qualidade dos estudos, avaliada pelo protocolo STROBE, apresentou uma classificação média de 79,1%. Nos estudos analisados, idade > 65 ou > 60 anos, performance status ECOG > 2, hipercalcemia, aumento de lactato desidrogenase (LDH), aumento da creatinina, plaquetopenia e hipoalbuminemia foram encontrados como preditores de prognóstico ruim. Foram também demonstradas alterações citogenéticas consideradas de alto risco, como as translocações e deleções de genes. Diversas condições clínicas, laboratoriais e citogenéticas parecem estar associadas ao pior prognóstico na LCP. O conhecimento desses fatores pode interferir na prática clínica. Entretanto, ainda são necessários estudos mais robustos, multicêntricos e com maior número amostral para aprofundar o conhecimento sobre essa patologia.


Plasma Cell Leukemia (PCL) is rare and aggressive hematologic disorder, with no consensus on the best therapeutic scheme or disease prognosis. Some studies consider it to be a variant of multiple myeloma. This research sought to report a PCL case and to present a systematic literature review on its prognostic factor related. Bibliographic search followed the PRISMA protocol, and was conducted on the PubMED database to identify studies on PCL prognostic factors. Of the 260 articles identified, only ten were included after application of exclusion criteria. Of these, eight evaluated clinical and laboratorial prognostic factors; five assessed cytogenetic factors; and only one investigated age as a prognostic factor. Quality of the selected studies was evaluated by STROBE protocol, presenting a median classification of 79.1%. Age >65 or >60 years old, status performance ECOG>2, hypercalcemia, increased DHL, increased creatinine, thrombocytopenia, and hypoalbuminemia were the factors identified as predictors of a bad prognosis. Studies also showed high-risk cytogenetic abnormalities such as genetic translocation and deletions. Many clinical, laboratorial and cytogenetic conditions seem to be related to a worse PCL prognosis. Since knowledge of these factor can interfere in the clinical practice, more robust studies are needed on this pathology.

El objetivo de este estudio fue realizar un reporte de caso y desarrollar una revisión sistemática de la literatura sobre los factores pronósticos relacionados con esta enfermedad. Esta revisión sistemática siguió el protocolo PRISMA, utilizó PubMED como base de datos para la búsqueda de estudios que evaluaran los factores pronósticos para LCP. Los estudios seleccionados fueron posteriormente evaluados por su calidad mediante el protocolo STROBE. La primera búsqueda identificó 260 artículos. Después de aplicados los criterios de exclusión, se seleccionaron diez. De estos, ocho evaluaron los factores pronósticos clínicos y de laboratorio, cinco evaluaron también los factores citogenéticos y uno evaluó la edad solo como factor pronóstico. La calidad de los estudios, evaluada por el protocolo STROBE, presentó una calificación promedio del 79,1%. En los estudios analizados, la edad > 65 o > 60 años, el estado funcional ECOG > 2, la hipercalcemia, el aumento de lactato deshidrogenasa (LDH), el aumento de creatinina, la trombocitopenia y la hipoalbuminemia fueron los predictores de mal pronóstico. También se demostraron alteraciones citogenéticas que se consideraron de alto riesgo, como translocaciones y deleciones de genes. Varias condiciones clínicas, de laboratorio y citogenéticas parecen estar asociadas con peor pronóstico en LCP. El conocimiento de estos factores puede interferir en la práctica clínica. Sin embargo, aún se necesitan estudios más robustos, multicéntricos y con mayor tamaño muestral para profundizar en el conocimiento sobre esta patología.

ABSTRACT

Severe hypercalcemia may cause acute pancreatitis. We report a 75-yearold male presenting with abdominal pain and confusion. The initial laboratory showed elevated amylase levels and a serum calcium of 19.0 mg/dl with highly elevated parathormone levels. An abdominal CT scan disclosed pancreatitis. A neck CT scan showed a parathyroid tumor, which was successfully excised. The pathology of the surgical piece showed a parathyroid adenoma.

ABSTRACT

Las urgencias oncológicas son complicaciones comunes de la evolución natural del tumor o de su manejo. Algunas pueden presentarse de manera sutil y ser pasadas por alto, lo que aumenta la morbimortalidad. El objetivo de esta revisión narrativa es recopilar información actualizada de las principales complicaciones oncológicas, para ello se realizó una revisión de artículos originales, revisiones sistemáticas y narrativas en bases de datos como Scopus, SciELO, PubMed, ScienceDirect y en el buscador Google Scholar. Se seleccionaron 63 referencias que mostraran información relevante acerca de las urgencias oncológicas planteadas para el desarrollo del artículo. En la revisión se discute que las complicaciones pueden clasificarse de acuerdo con su origen en infecciosas (neutropenia febril), metabólicas (síndrome de lisis tumoral e hipercalcemia maligna) y obstructivas (síndrome de vena cava superior, obstrucción intestinal, compresión medular y taponamiento cardiaco). El diagnóstico requiere un alto índice de sospecha, el médico debe tener la capacidad resolutiva y el conocimiento necesarios para el manejo y hacer uso racional de los recursos diagnósticos. Es necesario adoptar medidas terapéuticas que impacten positivamente en el pronóstico y que reduzcan la morbimortalidad.


Oncological emergencies are common complications resulting from the natural evolution of the tumor or its management; however, some of them may be subtle or even overlooked, which contributes to greater morbidity and mortality. Our aim was to gather updated information on the main oncological complications. A narrative literatura review was performed by searching for original articles, systematic reviews and narratives, in databases such as Scopus, SciELO, PubMed, ScienceDirect and in the Google Scholar search engine. 63 references were selected that addressed relevant information about the oncological emergencies raised for the development of the article. According to their origin, complications can be classified into infectious (febrile neutropenia), metabolic (tumor lysis syndrome and malignant hypercalcemia) and obstructive (superior vena cava syndrome, intestinal obstruction, spinal cord compression and cardiac tamponade). Facing these complications requires a high level of suspicion; the physician must be able to resolve each complication and have the necessary knowledge to approach each case, with a rational use of diagnostic resources. It is also necessary to adopt therapeutic measures that positively impact patients. patient prognosis, decreasing morbidity and death.

ABSTRACT

Introducción. La hipocalcemia es la complicación más frecuente de la tiroidectomía. La profilaxis con calcio/calcitriol es una alternativa costo-efectiva, sencilla y expedita para disminuir esta situación, sin alterar la función paratiroidea residual. Lo que no está claro es si hay superioridad de una dosis frente a otra, por lo que el objetivo de este estudio fue evaluar el comportamiento entre diferentes esquemas de profilaxis para hipocalcemia. Métodos. Estudio de cohorte retrospectivo de adultos operados en un hospital de cuarto nivel, entre febrero de 2017 y diciembre de 2020. Se calculó la tasa de síntomas, la hipocalcemia e hipercalcemia bioquímica en el control postquirúrgico durante las siguientes dos semanas. Se hizo análisis bivariado y multivariado entre dosis de calcio/calcitriol, otros factores asociados y los desenlaces mencionados. Resultados. Se incluyeron 967 pacientes. El 10 % presentaron síntomas. No hubo diferencias significativas en el calcio sérico del control posquirúrgico entre los grupos con distintas dosis de calcio. La dosis de carbonato de calcio >3600 mg/día y el calcio en las primeras 24 horas de cirugía se asociaron a la presencia de síntomas. La dosis de calcitriol <1 mcg/día y el bocio aumentaron el riesgo de hipocalcemia bioquímica, mientras que la dosis de 1,5 mcg/día lo disminuyó. Ninguna variable evaluada se asoció a hipercalcemia bioquímica. Conclusiones. Podemos establecer que dosis altas de carbonato de calcio no se asocian con menos hipocalcemia bioquímica, lo cual está a favor de usar dosis intermedias (3600 mg/día). De forma similar, la dosis de calcitriol de 1,5 mcg/día disminuye el riesgo de este desenlace. La identificación de variables que aumentan o disminuyen el riesgo de hipocalcemia posterior a tiroidectomía, como bocio o el nivel de calcio en las primeras 24 horas para este estudio, pueden determinar ajustes individuales en la dosis rutinaria profiláctica de calcio/calcitriol.


Introduction. Hypocalcemia is the most frequent complication of thyroidectomy. Calcium/calcitriol prophylaxis is a cost-effective, simple and expeditious alternative to reduce this situation, without altering residual parathyroid function. It is not clear whether there is superiority of one dose over another, so the objective of this study was to evaluate the behavior between prophylaxis doses for hypocalcemia. Methods. Retrospective cohort study of adults operated in a fourth level hospital, between February 2017 and December 2020. The rate of symptoms, biochemical hypocalcemia and hypercalcemia was calculated in the post-surgical control during the following two weeks. Bivariate and multivariate analyses were performed between calcium/calcitriol dose, other associated factors, and the mentioned outcomes. Results. Out of the 967 patients included, 10% presented symptoms. There were no significant differences in postoperative control serum calcium between the groups with different doses of calcium. The dose of calcium carbonate > 3600 mg/day and calcium in the first 24 hours of surgery were associated with the presence of symptoms. The dose of calcitriol <1 mcg/day and goiter increased the risk of biochemical hypocalcemia, while the dose of 1.5 mcg / day decreased it. No variable evaluated was associated with biochemical hypercalcemia. Conclusion. We can establish that high doses of calcium are not less associated with biochemical hypocalcemia, which is in favor of intermediate doses (i.e. 3600mg/day). In a similar way, the calcitriol dose of 1.5mcg/day decreases the risk of this outcome. The identification of variables that increase or decrease the risk of this complication (goiter or the 24h serum calcium in this study) can decide settings in the rutinary prophylactic dose of calcium/calcitriol.

ABSTRACT

La crisis hipercalcémica (CH) es una emergencia endocrina inusual, definida por la presencia de calcemia > 14 mg/dl asociada a disfunción renal, alteraciones cardiovasculares, gastrointestinales y del sensorio; también podría considerarse en pacientes con síntomas graves y calcemia menor. El hiperparatiroidismo primario (HPTP) y las neoplasias malignas son las etiologías más comunes de la hipercalcemia (90% de los casos); sin embargo, rara vez el primero se presenta como CH. Debido a la alta mortalidad asociada a esta entidad, es de gran importancia establecer diagnóstico y tratamiento precoces. Presentamos dos pacientes con crisis hipercalcémica como primera manifestación del HPTP, el 1.° con bloqueo auriculoventricular (AV) completo y el 2.° con pancreatitis aguda. La anatomía patológica (AP) reveló adenoma oxifílico en ambos casos, que es una variante histológica poco frecuente y puede manifestarse clínicamente de forma grave. Conclusiones: los adenomas paratiroideos son causa poco frecuente de CH. Consideramos el tipo histológico observado (adenoma oxifílico) como probable factor condicionante. La pancreatitis y especialmente el bloqueo AV son manifestaciones poco frecuentes de la CH. Resaltamos la importancia de la determinación de los niveles de calcio dentro de la evaluación inicial de todo paciente con bloqueo AV. (AU)


Hypercalcemic crisis (HC) is an unusual endocrine emergency, defined as the presence of serum calcium > 14 mg/dl related to kidney dysfunction, cardiovascular, gastrointestinal and sensory disturbances. It could also be considered in patients with severe symptoms and lower serum calcium levels. Primary hyperparathyroidism (PHPT) and malignant neoplasms are the most common hypercalcemia etiologies (90% of cases), nevertheless, the former hardly ever occurs as HC. Due to the high mortality associated with HC, it is crucial to establish early diagnosis and treatment.We report two patients with HC as the first manifestation of PHPT; the former with atrioventricular (AV) block and the latter with acute pancreatitis. Pathology revealed oxyphilic adenoma in both cases, which is an infrequent histological variant that can have a severe clinical manifestation. Conclusions: parathyroid adenomas are a rare cause of HC. We consider the histological type observed (oxyphilic adenoma) as a probable conditioning factor. Pancreatitis and especially AV block are rare manifestations of HC. We emphasize the importance of determining calcium levels in the initial evaluation of all patients with AV block. (AU)

ABSTRACT

Introduction. Familial hypocalciuric hypercalcemia is a rare inherited calcium metabolism disorder in which an alteration of the parathyroid hormone secretion set-point causes hypercalcemia with relative hypocalciuria. Some data suggest that its prevalence is around 74.1 per 100,000 inhabitants. Often, patients are asymptomatic. However, they can develop mild symptoms and an overactive parathyroid adenoma, its main differential diagnosis. The objective was to describe a patient's case and highlight the importance of clinical suspicion and diagnosis to avoid unnecessary surgical neck explorations for parathyroid adenomas. Case report. This is the case of a 40-year-old man with a biochemical profile compatible with primary hyperparathyroidism with anatomical and functional images negative for adenoma and a calcium/creatinine clearance ratio below 0.001, considering familial hypocalciuric hypercalcemia. Genetic studies evidence a mutation in the calcium sensor receptor gene and confirm the diagnosis. Discussion. Familial hypocalciuric hypercalcemia's main differential diagnosis is an overactive parathyroid adenoma. For both, mild or no symptoms may be present; serum calcium exceeds the upper limit, and parathormone is more than 25pg/ml. The calcium/creatinine clearance ratio should be used to differentiate one from the other and avoid unnecessary surgical neck explorations. Besides the lack of information on this topic, evidence supports the use of calcimimetics to treat symptomatic hypercalcemia. Conclusions. Patients with mild hypercalcemia with parathyroid hormone readings above 25pg/ml and a calcium/creatinine clearance ratio below 0.001, or patients with primary hyperparathyroidism with negative imaging, should not undergo surgical neck explorations. In these cases, familial hypocalciuric hypercalcemia is a reliable diagnosis; Cinacalcet may be administered in cases of symptomatic hypercalcemia.


Introducción. La hipercalcemia hipocalciúrica familiar es un trastorno hereditario poco común del metabolismo del calcio en donde una alteración del punto de ajuste de la secreción de hormona paratiroidea ocasiona hipercalcemia con hipocalciuria relativa. Algunos datos sugieren que su prevalencia es de alrededor de 74.1 por 100,000 habitantes. Los pacientes muchas veces son asintomáticos. Sin embargo, pueden desarrollar síntomas leves y un adenoma paratiroideo hiperactivo, que representa su principal diagnóstico diferencial. El objetivo fue describir el caso de un paciente y resaltar la importancia de la sospecha y el diagnóstico clínico para evitar exploraciones quirúrgicas cervicales innecesarias en búsqueda de adenomas paratiroideos. Reporte de caso. Este es el caso de un hombre de 40 años con un perfil bioquímico compatible con hiperparatiroidismo primario, con imágenes anatómicas y funcionales negativas para adenoma, además de una relación de depuración de calcio/creatinina menor a 0.001, con consideración de hipercalcemia hipocalciúrica familiar. Los estudios genéticos evidencian una mutación en el gen del receptor sensor del calcio y confirman el diagnóstico. Discusión. El principal diagnóstico diferencial de la hipercalcemia hipocalciúrica familiar es un adenoma paratiroideo hiperactivo. En ambos casos, es posible que no haya síntomas o que estos sean leves; el calcio sérico excede al límite superior, y la paratohormona es mayor de 25pg/ml. Se debe usar la relación de depuración de calcio/creatinina para diferenciar entre estas patologías y evitar exploraciones quirúrgicas cervicales innecesarias. Aparte de la falta de información sobre este tema, la evidencia apoya el uso de calciomiméticos para tratar la hipercalcemia sintomática. Conclusiones. Los pacientes con hipercalcemia leve, con valores de hormona paratiroidea mayores de 25pg/ml y con una relación de depuración de calcio/creatinina menor de 0.001, o los pacientes con hiperparatiroidismo primario con imágenes negativas, no deben ser sometidos a exploraciones quirúrgicas cervicales. En estos casos, la hipercalcemia hipocalciúrica familiar representa un diagnóstico confiable; se puede administrar Cinacalcet en casos de hipercalcemia sintomática.


Introdução. A hipercalcemia hipocalciúrica familiar é um distúrbio hereditário raro do metabolismo do cálcio, no qual uma alteração no ponto de ajuste da secreção do hormônio da paratireóide causa hipercalcemia com hipocalciúria relativa. Alguns dados sugerem que sua prevalência gira em torno de 74.1 por 100,000 habitantes. Os pacientes geralmente são assintomáticos. No entanto, eles podem desenvolver sintomas leves e um adenoma de paratireoide hiperativo, que representa seu principal diagnóstico diferencial. O objetivo foi descrever o caso de um paciente e destacar a importância da suspeita clínica e do diagnóstico para evitar exploração cirúrgica cervical desnecessária em busca de adenomas de paratireoide. Relato de caso. É o caso de um homem de 40 anos com perfil bioquímico compatível com hiperparatireoidismo primário, com imagens anatômicas e funcionais negativas para adenoma, além de relação depuração de cálcio/creatinina menor que 0.001, considerando hipercalcemia hipocalciúrica familiar. Estudos genéticos revelam uma mutação no gene receptor da sensibilidade ao cálcio e confirmam o diagnóstico. Discussão. O principal diagnóstico diferencial da hipercalcemia hipocalciúrica familiar é um adenoma de paratireoide hiperativo. Em ambos os casos, os sintomas podem estar ausentes ou leves; o cálcio sérico excede o limite superior e o hormônio da paratireóide é superior a 25pg/ml. A relação depuração de cálcio/creatinina deve ser usada para diferenciar entre essas patologias e evitar exploração cirúrgica cervical desnecessária. Além da falta de informações sobre esta questão, as evidências apoiam o uso de calcimiméticos para tratar a hipercalcemia sintomática. Conclusões. Pacientes com hipercalcemia leve, com valores de hormônio da paratireóide maiores que 25pg/ml e uma relação de depuração de cálcio/creatinina menor que 0.001, ou pacientes com hiperparatireoidismo primário com imagens negativas, não devem ser submetidos a exploração cirúrgica cervical. Nesses casos, a hipercalcemia hipocalciúrica familiar representa um diagnóstico confiável; Cinacalcet pode ser administrado em casos de hipercalcemia sintomática.

ABSTRACT

Abstract PTH-independent hypercalcemia due to granulomatous disease is well-documented and sarcoidosis is the most characteristic disease, although there are others. We describe a case of sarcoid-like granulomatous myositis. An 87-year-old man was referred with tetraparesis and hypercalcemia (albumin-corrected calcium of 13.4 mg/dl) following a trip to the Caribbean. The evaluation showed a suppressed PTH, 25-hydroxy vitamin D of 7.5 ng/ml, 18F-FDG PET/CT showed markedly increased uptake in intercostal, back, shoulder, but tock and thigh muscles and a deltoid biopsy confirmed extensive granulomatous myositis. He was prescribed glucocorticoids which resulted in normalized plasma calcium levels and complete recovery from tetraparesis. Sarcoid-like granulomatous myositis should be incorporated into the differential diagnosis of PTH-independent hypercalcemia, especially in the absence of clinical features of sarcoidosis and with special emphasis on the use of 18F-FDG PET/CT to ensure a correct approach.


Resumen La hipercalcemia PTH-independiente asociada a enfermedades granulomatosas está bien documentada y la sarcoidosis es la enfermedad más característica, a pesar de que existen otras. Des cribimos un caso de miositis granulomatosa simil-sarcoidea. Un hombre de 87 años consultó por tetraparesia e hipercalcemia (calcio corregido por albúmina 13.4 mg/dl) luego de un viaje al Caribe. La evaluación mostró una PTH suprimida, 25-hidroxivitamina D 7.5 ng/ml, 18F-FDG PET/CT mostró marcado aumento de captación a nivel de musculatura intercostal, dorsal, deltoidea, glúteos y muslos. Una biopsia deltoidea confirmó una miositis granulomatosa extensa. Se prescribieron glucocorticoides, resultando en normalización del calcio plasmático y completa recuperación de la tetraparesia. La miositis granulomatosa simil-sarcoidea debe ser incorporada den tro del diagnóstico diferencial de la hipercalcemia PTH-independiente, especialmente en ausencia de hallazgos clínicos de sarcoidosis y con especial énfasis en el uso de 18F-FDG PET/CT para su correcta aproximación.

ABSTRACT

Abstract 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.

ABSTRACT

La hipercalcemia asociada a tumores malignos es una entidad poco frecuente en pediatría (0,5-1,3 % de los cánceres pediátricos). Es causada por diferentes mecanismos fisiopatológicos y los síntomas de presentación suelen ser inespecíficos, pero potencialmente graves. Presentamos un caso clínico de una paciente de 12 años con diagnóstico de disgerminoma ovárico bilateral. La enfermedad se presentó con hipercalcemia grave, tratada con hiperhidratación asociada a diuréticos de asa, bifosfonatos y, por último, la resección quirúrgica del tumor, que permitió la resolución definitiva del cuadro. A pesar de tratarse de un trastorno hidroeléctrico poco habitual en pediatría, dada la potencial gravedad de la hipercalcemia, es importante la detección y el tratamiento tempranos, con el fin de evitar complicaciones en el corto y el largo plazo


Hypercalcemia associated with malignant tumors is a rare entity in pediatrics (0.5-1.3 % of pediatric cancers). It responds to different pathophysiological mechanisms and the typical symptoms shown are usually nonspecific, but potentially serious. We present a clinical case of a 12-year-old patient with a bilateral ovarian dysgerminoma who was diagnosed with severe hypercalcemia at the onset, which required hyperhydration associated with loop diuretics, bisphosphonates and, eventually, the tumor resection surgery that allowed the final resolution of the clinical picture.Despite being a rare hydroelectric disorder in pediatrics, given the potential severity of hypercalcemia, early detection and treatment are important in order to avoid potential short- and long-term complications.

ABSTRACT

Parathyroid carcinoma is a rare malignant disease that presents as a sporadic or familial primary hyperparathyroidism (PHP). The latter is associated with some genetic syndromes. It occurs with equal frequency in both sexes, unlike PHP caused by parathyroid adenoma that is more common in women. It should be suspected in cases of severe hypercalcemia, with high parathyroid hormone levels and a palpable cervical mass. Given the difficulty in distinguishing between parathyroid carcinoma and adenoma prior to the surgery, the diagnosis is often made after parathyroidectomy. The only curative treatment is complete surgical resection with oncologic block resection of the primary tumor to ensure free margins. Adjuvant therapies with chemotherapy or radiation therapy do not modify overall or disease-free survival. Recurrences are common and re-operation of resectable recurrent disease is recommended. The palliative treatment of symptomatic hypercalcemia is crucial in persistent or recurrent disease after surgery since morbidity and mortality are more associated with hypercalcemia than with tumor burden.

ABSTRACT

El carcinoma paratiroideo (CP) es una neoplasia maligna con una incidencia de 0,015 cada 100.000 habitantes por año. Representa el 1% de los diagnósticos de hiperparatiroidismo primario y se manifiesta entre la 4.a y 5.a década de la vida, con una incidencia similar entre hombres y mujeres. La etiología del CP es incierta, ha sido asociada a formas esporádicas o familiares. Está caracterizado por altos niveles séricos de calcio y PTH y el desafío clínico-quirúrgico es el diagnóstico diferencial con otras entidades benignas como el adenoma o la hiperplasia de paratiroides. Aunque el diagnóstico de certeza es anatomopatológico, la sospecha clínica y el uso de métodos de baja complejidad (ecografía) con operadores avezados permite una correcta localización y abordaje pertinente del paciente para dirigir el tratamiento quirúrgico adecuado (resección en bloque) evitando persistencias y recurrencias de enfermedad. Se presenta el caso clínico de un paciente masculino que ingresa por síndrome de impregnación asociado a hipercalcemia, su abordaje diagnóstico, tratamiento y manejo interdisciplinario con discusión y revisión bibliográfica. (AU)


Parathyroid carcinoma (CP) is a malignant disease with an incidence of 0.015 per 100,000 inhabitants per year. It accounts for 1% of primary hyperparathyroidism diagnoses and occurs between the 4th and 5th decade of life, with a similar incidence between men and women. The etiology of CP is uncertain and has been associated with sporadic or family forms. CP is characterized by high serum calcium and PTH levels and the clinical-surgical challenge is the differential diagnosis with other benign entities such as parathyroid adenoma or hyperplasia. Although the diagnosis of certainty is achieved by pathological anatomy examination, the clinical suspicion and the use of low complexity methods (ultrasound) by experienced operators allows a correct localization and a patient-specific approach to direct the appropriate surgical treatment (block resection), avoiding persistence and recurrences of disease. The clinical case of a male patient admitted for severe hypercalcemia with multiple organ disfunction, the diagnostic approaches, treatment, and interdisciplinary management, together with review and discussion of the current literature are presented.
