Treatment-induced diabetes neuropathy: description of singular clinical signs to reach a prompt diagnosis.

A 23-year-old woman diagnosed with type 1 diabetes mellitus in 2011 came to our outpatient office because of an inability to walk correctly. She was under a basal bolus insulin regimen. In the summer of 2016, she experienced a rapid improvement in her glycaemic control. A few weeks later, she started to complain of a severe burning pain in the soles of her feet (pain score 10/10). Neither macrovascular nor microvascular complications were detected. The patient was forced to walk barefoot due to an intense pain using shoes or socks and used to soak her feet in water for several hours daily. She also developed severe intolerance to environmental heat, both indoors and outdoors. A diagnosis of treatment-induced diabetic neuropathy was made. The patient was admitted to a general ward to start pain therapy. After a 6-month course of different neuropathic pain drugs, the patient was able to walk autonomously again.

Nuevas tecnologías en la evaluación de la fragilidad ósea y su aplicación en Endocrinología / New technologies in the evaluation of bone fragility and its application in Endocrinology

La medición de la densidad mineral ósea mediante la absorciometría radiológica de doble energía es la técnica de elección para la valoración ósea y un predictor importante del riesgo de fractura. Sin embargo, la mayoría de las fracturas por fragilidad ocurren en personas sin osteoporosis densitométrica, especialmente en enfermedades endocrinológicas. Las herramientas para la estimación del riesgo de fracturas como FRAX han mejorado la sensibilidad diagnóstica aunque no consideran otras características óseas adicionales. La investigación de la microarquitectura ósea supone una mejoría en el abordaje de estos pacientes. En este documento elaborado por miembros del grupo de trabajo de Metabolismo Mineral y Óseo de la Sociedad Española de Endocrinología y Nutrición se revisan los nuevos avances en absorciometría radiológica de doble energía y otras técnicas más complejas para el estudio de la microarquitectura ósea así como los datos disponibles en diabetes tipo 2 y patología paratiroidea

Bone mineral density using dual-energy X-ray absorptiometry is the gold standard for the assessment of bone and an important predictor of fracture risk. However, most fragility fractures occur in people without densitometric osteoporosis, especially in endocrinological diseases. Fracture risk estimation tools such as FRAX have improved diagnostic sensitivity but do not include additional skeletal features. Bone microarchitecture research represents an improvement in the treatment of these patients. In this document members of the Mineral and Bone Metabolism Working Group of the Spanish Society of Endocrinology and Nutrition review new advances in dual-energy X-ray absorptiometry and other complex techniques for the study of bone microarchitecture as well as the available data on type 2 diabetes and parathyroid pathology

Trastornos del fosfato y actitud clínica ante situaciones de hipofosfatemia e hiperfosfatemia / Phosphate disorders and clinical management of hypophosphatemia and hyperphosphatemia

La concentración sérica de fósforo oscila entre 2,5 y 4,5 mg/dl (0,81-1,45 mmol/l) en adultos, con niveles más altos en la infancia, la adolescencia y durante la gestación. El fosfato intracelular está implicado en el metabolismo intermediario y otras funciones celulares esenciales, mientras que el extracelular es fundamental para la mineralización de la matriz ósea. La fosforemia se mantiene en un estrecho rango mediante la regulación de la absorción intestinal, la redistribución y la reabsorción tubular renal de fósforo. La hipofosfatemia y la hiperfosfatemia son situaciones clínicas frecuentes, aunque, en la mayoría de las ocasiones, se trata de alteraciones leves y poco sintomáticas. Sin embargo, pueden presentarse cuadros agudos y severos que requieren tratamiento específico. En este documento elaborado por miembros del Grupo de Trabajo de Metabolismo Mineral y Óseo de la Sociedad Española de Endocrinología y Nutrición se revisan los trastornos del fosfato y se proporcionan algoritmos de manejo clínico de la hipofosfatemia y la hiperfosfatemia

Serum phosphorus levels range from 2.5 and 4.5 mg/dL (0.81-1.45 mmol/L) in adults, with higher levels in childhood, adolescence, and pregnancy. Intracellular phosphate is involved in intermediary metabolism and other essential cell functions, while extracellular phosphate is essential for bone matrix mineralization. Plasma phosphorus levels are maintained within a narrow range by regulation of intestinal absorption, redistribution, and renal tubular absorption of the mineral. Hypophosphatemia and hyperphosphatemia are common clinical situations, although changes are most often mild and oligosymptomatic. However, acute and severe conditions that require specific treatment may occur. In this document, members of the Mineral and Bone Metabolism Working Group of the Spanish Society of Endocrinology and Nutrition review phosphate disorders and provide algorithms for adequate clinical management of hypophosphatemia and hyperphosphatemia

[Anemia in critically ill and surgical patient: treatment with intravenous iron]. / Anemia del paciente crítico y quirúrgico: tratamiento con hierro intravenoso.

BACKGROUND: Anemia is a common condition among surgical and critically ill patients and it is usually treated with allogenic blood transfusion (ABT). As ABT is associated with increased morbidity and mortality, alternative therapies for anemia in these patients are actively investigated. OBJECTIVES: To asses the potential usefulness of intravenous iron therapy in critically-ill or surgical patients with anemia. METHODS: Review of published papers with intravenous iron in these patients. Bibliographical search on database Medline (www.ncvi.nlm.nih.gov). RESULTS AND DISCUSSION: Treatment with intravenous iron is not sufficient to treat the anemia of critically ill patients. Its association with erythropoietin (EPO) may have an effect on the rate of ABT, but it has not been shown to improve morbidity, mortality or length of hospital stay. In gastrointestinal or trauma surgery there is no evidence to support the routine preoperative treatment with intravenous iron, although it may be beneficial when it is used with erythropoietin. Intravenous iron alone or in combination with EPO in the postoperative period has not been proved useful for rapid correction of anemia, reduction of hospital stay or mortality.

Serum 25 OH vitamin D concentrations and calcium intakeare low in patients with prostate cancer

Objective: To evaluate dietary calcium intake (DCI) and vitamin D serum concentrations in patients with prostate cancer. Methods: We conducted a cross-sectional study including 91 subjects with prostate cancer. We determined DCI by a questionnaire, 25 OH vitamin D levels and bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA).Results: According to current guidelines (1000 mg/day), calcium intake was low in patients with prostate cancer (394±201 mg/day). Twenty-two percent (20) of patients had adequate levels of vitamin D, whereas 29.7% (27) of patients were vitamin D deficient and 48.3% (44) were classified as vitamin D insufficiency. Vitamin D levels were not different in patients with or without androgen-deprivation therapy. There were no correlation between DCI, 25 OH vitamin and BMD. Conclusions: In summary, in our group of prostate cancer patients DCI was low and vitamin D deficiency is highly prevalent. Although this is a common condition in other populations, in this group of patients especially prone to osteoporosis could have more relevance. Additional research is needed to establish the consequences of low calcium intake and vitamin D deficiency in prostate cancer patients (AU)

Objetivo: Evaluar la ingesta dietética de calcio (DCI) y las concentraciones de vitamina D en pacientes con cáncer de próstata. Métodos: Estudio transversal que incluyó a 91 pacientes con cáncer de próstata. Se determinó la ingesta dietética de calcio a través de un cuestionario, las concentraciones séricas de 25 OH vitamina D y la densidad mineral ósea por dual energy X-ray absorptiometry (DXA). Resultados: Según las recomendaciones actuales (1000 mg/día) la ingesta dietética de calcio fue baja en pacientes con cáncer de próstata (394±201 mg/día). 22% (20) de los pacientes presentaron concentraciones adecuadas de vitamina D, mientras que el 29,7% (27) fueron deficitarios y el 48.3% (44) se clasificó como insuficiencia de vitamina D. Las concentraciones de vitamina D no mostraron diferencias de acuerdo al tratamiento o no con terapia de deprivación androgénica. No existió correlación entre la ingesta diaria de calcio, las concentraciones de vitamina D o la densidad mineral ósea. Conclusiones: En nuestro grupo de pacientes con cáncer de próstata la DCI es baja y el déficit de vitamina D es muy prevalente. Aunque esta es una situación frecuente en otros grupos de población, en este grupo de pacientes especialmente predispuestos al desarrollo de osteoporosis podría tener una mayor relevancia. Son necesarios estudios adicionales para establecer las consecuencias de estas dos situaciones en pacientes con cáncer de próstata (AU)
