          Abstract

          Objetivo: Evaluar la utilidad de los métodos de diagnóstico, la efectividad de la paratiroidectomía y sus complicaciones. Sede: Hospital de Especialidades del Centro Médico Nacional Siglo XXI. Diseño: Estudio retrospectivo, descriptivo, observacional, transversal. Análisis estadístico: Medidas de tendencia central más pruebas de valor diagnóstico. Pacientes y método: Se incluyeron 21 pacientes adultos consecutivos operados por hiperparatiroidismo primario (HPTP), del 1 de enero al 31 de diciembre de 2009. Las variables analizadas fueron: edad, género, antecedentes familiares de patología paratiroidea, manifestaciones clínicas, cuantificación de niveles séricos de calcio, fósforo y hormona paratiroidea en preoperatorio y postoperatorio, depuración de creatinina y densitometría ósea; valor diagnóstico de estudios preoperatorios de localización y reporte histopatológico. Resultados: El 90% de los pacientes perteneció al sexo femenino y la edad media fue de 57 años. La nefrolitiasis, hipertensión arterial sistémica y fatiga fueron las manifestaciones clínicas y entidades asociadas con mayor frecuencia a hiperparatiroidismo primario. La ultrasonografía y la centellografía mostraron baja sensibilidad, bajo valor predictivo positivo, moderada especificidad y moderado valor predictivo negativo. El abordaje quirúrgico fue unilateral en 10 pacientes (47.5%), bilateral en 52.5%; la efectividad terapéutica fue de 85.7% en la primera intervención y 100% en la reintervención. Se registraron complicaciones en el 4.7% de los pacientes. Conclusión: En esta serie los pacientes con hiperparatiroidismo primario presentaron nefrolitiasis con mayor frecuencia; la sensibilidad diagnóstica de la ultrasonografía y centellografía en relación con la localización específica de las glándulas es inferior a lo informado. Se tuvo alta efectividad quirúrgica de la paratiroidectomía y baja frecuencia de complicaciones.

          Objective: To assess the usefulness of the diagnostic methods and the efficacy of parathyroidectomy and its complications. Setting: Third level health care center (Specialty Hospital of the National Medical Center ''Siglo XXI'') Design: Retrospective, descriptive, observational, cross-sectional study. Statistical analysis: Central tendency measures and diagnostic value tests. Patients and method: The study included 21 consecutive adult patients subjected to surgery due to primary hyperparathyroidism (PHPT) from January 1st to December 31st 2009. Analyzed variables were: age, gender, familial antecedents of parathyroid pathology, clinical manifestations, pre-operative and post-operative serum levels of calcium, phosphorus, and parathyroid hormone levels, creatinine depuration, bone densitometry; diagnostic value of preoperative location study and histopathological report. Results: Ninety percent of patients were women with a mean age of 57 years. Nephrolithiasis, systemic arterial hypertension, and fatigue were the clinical manifestations most frequently associated with primary hyperparathyroidism. Ultrasonography and scintigraphy showed low sensitivity, low positive predictive value, moderate specificity, and moderate negative predictive value. Surgical approach was unilateral in 10 patients (47.5%), bilateral in 52.5%; therapeutic efficacy was of 85.7% for the first intervention, and of 100% for re-intervention. Complications were encountered in 4.7% of patients. Conclusion: In this series, patients with primary hyperparathyroidism presented nephrolithiasis more frequently, sensitivity of ultrasonography and scintigraphy in relation to specific location of glands was lower than reported. High surgical efficacy of the parathyroidectomy was achieved with low frequency of complications.

          Guidelines for the management of asymptomatic primary hyperparathyroidism: summary statement from the third international workshop.

          Asymptomatic primary hyperparathyroidism (PHPT) is a common clinical problem. The purpose of this report is to guide the use of diagnostics and management for this condition in clinical practice. Interested professional societies selected representatives for the consensus committee and provided funding for a one-day meeting. A subgroup of this committee set the program and developed key questions for review. Consensus was established at a closed meeting that followed and at subsequent discussions. Each question was addressed by a relevant literature search (on PubMed), and the data were presented for discussion at the group meeting. Consensus was achieved by a group meeting. Statements were prepared and reviewed by all authors who represented the Planning Committee and the participating professional societies.

            Parathyroid imaging: technique and role in the preoperative evaluation of primary hyperparathyroidism.

            This article discusses the commonly used techniques for imaging the parathyroid glands and their role in the preoperative evaluation of patients with primary hyperparathyroidism. The importance of sonography and sestamibi scintigraphy in the preoperative evaluation of patients with primary hyperthyroidism has increased with the adoption of minimally invasive parathyroidectomy techniques at most medical centers. When the results of these studies are concordant, the cure rates of minimally invasive surgery equal those of traditional bilateral neck exploration.

              Presentation of asymptomatic primary hyperparathyroidism: proceedings of the third international workshop.

              At the Third International Workshop on Asymptomatic Primary Hyperparathyroidism (PHPT) in May 2008, recent data on the disease were reviewed. We present the results of a literature review on issues arising from the clinical presentation and natural history of PHPT. Questions were developed by the International Task Force on PHPT. A comprehensive literature search for relevant studies was reviewed, and the questions of the International Task Force were addressed by the Consensus Panel. 1) Data on the extent and nature of cardiovascular involvement in those with mild disease are too limited to provide a complete picture. 2) Patients with mild PHPT have neuropsychological complaints. Although some symptoms may improve with surgery, available data remain inconsistent on their precise nature and reversibility. 3) Surgery leads to long-term gains in spine, hip, and radius bone mineral density (BMD). Because some patients have early disease progression and others lose BMD after 8-10 yr, regular monitoring (serum calcium and three-site BMD) is essential in those followed without surgery. Patients may present with normocalcemic PHPT (normal serum calcium with elevated PTH concentrations; no secondary cause for hyperparathyroidism). Data on the incidence and natural history of this phenotype are limited. 4) In the absence of kidney stones, data do not support the use of marked hypercalciuria (>10 mmol/d or 400 mg/d) as an indication for surgery for patients. 5) Patients with bone density T-score -2.5 or less at the lumbar spine, hip, or distal one third radius should have surgery.
