Una paciente con fenómeno de Raynaud del pezón e hipertiroidismo / A patient with Raynaud's phenomenon of the nipple and hyperthyroidism

Introducción: el fenómeno de Raynaud del pezón es una patología poco frecuente. Puede presentarse asociada a hipertiroidismo o enfermedades autoinmunes del tejido conectivo. Presentamos un caso asociado a hipertiroidismo.Caso clínico: mujer, de 39 años, que consulta por dolor en pezón que se agrava con la lactancia 1 mes después del parto. Se diagnosticó fenómeno de Raynaud del pezón, que mejoró con la toma de nifedipino. Tres meses después, la paciente presentó fiebre. El análisis de sangre mostró hormona estimulante del tiroides (TSH) 0,0008 mU/L (normal: 0,55-4,75 mU/L) y T4 libre 48 pg/mL (normal: 2,30-4,20 pg/mL). Los anticuerpos antitiroglobulina fueron > 500 UI/mL. La T3, los anticuerpos antiperoxidasa (TPO) y la inmunoglobulina estimulante del tiroides fueron normales. Se diagnosticó tiroiditis posparto (TPP). Dos meses después, los niveles de TSH y T4 libre volvieron a la normalidad.Conclusión: nuestra paciente presenta una TPP asociada a un fenómeno de Raynaud.(AU)

Introduction: Raynaud's phenomenon of the nipple is a rare pathology. It can occur associated with hyperthyroidism or autoimmune connective tissue diseases.We report a case associated with hyperthyroidism.Case study: a 39-year-old woman consulted for nipple pain, which worsened with breastfeeding, one month after childbirth. Raynaud's phenomenon of the nipple was diagnosed, which improved with nifedipine. Three months later the patient developed fever. Blood test revealed thyroid stimulating hormone (TSH) 0.0008 mU/L (normal 0.55-4.75 mU/L) and free T4 48 pg/mL (normal 2.30-4.20 pg/mL). Antithyroglobulin antibodies were >500 IU/mL. T3, antiperoxidase antibodies (TPO), and thyroid-stimulating immunoglobulin were normal. Postpartum thyroiditis (PPT) was diagnosed. Two months later, TSH and free T4 levels returned to normal.Conclusion: our patient presented PPT associated with Raynaud's phenomenon.(AU)

Impacto de la fragilidad y COVID-19 en una cohorte de gente mayor de la ciudad de Barcelona / Frailty impact on COVID-19 disease in an older cohort from the city of Barcelona

Objetivo: Describir la incidencia y mortalidad de COVID-19, durante la primera ola, en la población de personas mayores de Barcelona, según sus niveles previos de fragilidad. Diseño: Estudio de cohortes retrospectivo. Emplazamiento y participantes: Población de 65 o más años asignada a los centros de Atención Primaria de Barcelona del Institut Català de la Salut, seguidos entre marzo y junio de 2020. Mediciones principales: Fragilidad calculada al inicio a partir de la historia clínica informatizada. Resultados durante el seguimiento: diagnóstico de COVID-19, posible o confirmado con PCR y mortalidad por todas las causas. Resultados: Se analizaron 251788 mayores de 64 años. Un 61,3% tenían algún nivel de fragilidad, 27,8% moderada o grave. La incidencia de COVID-19 fue de 3,13 casos por 100 habitantes (N = 7883) y la mortalidad por COVID-19 fue del 21,5% (N =1 691). Tanto la incidencia como la mortalidad por COVID-19 fueron superiores a mayor edad, en hombres, a mayor privación y a mayor nivel de fragilidad. Los individuos con fragilidad leve, moderada y grave tuvieron un hazard ratio ajustado de enfermedad por COVID-19 de 1,47, 2,08 y 3,50 respectivamente. Entre los sujetos con COVID-19, aquéllos con fragilidad leve, moderada y grave tuvieron un hazard ratio ajustado de mortalidad por COVID-19 de 1,44, 1,69 y 2,47 respectivamente. Conclusiones: Consideramos necesario el abordaje de la fragilidad también en situación de pandemia, dado que es una condición tratable y a su vez factor de riesgo de COVID-19 más grave, donde el papel de la Atención Primaria es primordial, por su accesibilidad y longitudinalidad.(AU)

Objetive: To describe the incidence and mortality of the first wave of COVID-19 in the elderly population of Barcelona, according to their previous levels of frailty. Design: Retrospective cohort study. Setting and participants: Population aged 65 or over assigned to the Barcelona Primary Care centres of the Institut Català de la Salut, followed between March and June 2020. Main measurements: Frailty was calculated at baseline from the computerised medical records. Results during follow-up: diagnosis of COVID-19, possible or confirmed with PCR and all-cause mortality. Results: 251788 patients over 64 years of age were analysed, 61.3% had some level of frailty, 27.8% moderate or severe. The incidence of COVID-19 was 3.13 cases per 100 inhabitants (N=7883) and the mortality from COVID-19 was 21.5% (N=1691). Both the incidence and mortality from COVID-19 were higher at older age, in men, at greater deprivation and at a higher level of frailty. Individuals with mild, moderate, and severe frailty had an adjusted Hazard Ratio (HR) for COVID-19 disease of 1.47, 2.08, and 3.50, respectively. Among subjects with COVID-19, those with mild, moderate, and severe frailty had an adjusted HR for COVID-19 mortality of 1.44, 1.69, and 2.47, respectively. Conclusions: We consider it necessary to address frailty also in a pandemic situation, since it is a treatable condition and in turn a more serious risk factor for COVID-19, where the role of primary care is essential, due to its accessibility and longitudinal character.(AU)

[Sensitivity, specificity, positive and negative predictive values of the criteria for indicating a bone densitometry in the evaluation of medical techniques and research in Cataluña]. / Sensibilidad, especificidad y valor predictivo positivo y negativo de los criterios de indicación de densitometría ósea de la agencia de evaluación de tecnologías e investigación médicas de cataluña.

UNLABELLED: The Catalan Agency for Health Technology Assessment and Research (AETIM) proposed, in 2001, criteria for performing a bone densitometry (BD) for use in the consultations of the public health system. OBJECTIVE: To determine the sensitivity, specificity, positive predictive value and negative predictive value of the criteria to indicate BD. MATERIAL AND METHODS: Five groups of volunteers (premenopausal women aged 46 to 65 years, postmenopausal women aged 46 to 65 years, postmenopausal women aged> 65 years and men 46 to 65 years and> 65 years) underwent BD and a questionnaire on risk factors. The results obtained with the AETIM criteria are related to criteria for indication of BD proposed by the World Health Organization (1999 and 2003 criteria), the National Osteoporosis Foundation (1998 amd 2010 criteria) and the International Committee of Clinical Guidelines on Osteoporosis. RESULTS: Criteria from the Catalan Agency have low sensitivity to detect both low bone mass (T index<-1) and osteoporosis (T index<-2.5), specificity varied according to the group. The positive predictive value is low, but the negative predictive value for osteoporosis is high in all groups (except for postmenopausal women aged> 65 years). The remaining criteria have a high negative predictive value and, in women, good sensitivity and low specificity, especially for identifying patients with osteoporosis. CONCLUSION: Catalan Agency criteria are useful for selecting patients who would not need BD, but lack sufficient sensitivity to identify individuals with low bone mass. The other criteria also have a high negative predictive value for osteoporosis, and a better sensitivity.

Objetivo. La Agencia de Evaluación de Tecnologías e Investigación Médicas (AETIM) de Cataluña propuso en 2001 unos criterios de indicación de densitometría ósea (DO) para su uso en la consultas del sistema sanitario público. El objetivo fue conocer la sensibilidad, la especificidad, el valor predictivo positivo (VPP) y valor predictivo negativo (VPN) de los criterios de indicación de DO de la AETIM. Material y método. Cinco grupos de voluntarios (mujeres premenopáusicas de 46 a 65 años, posmenopáusicas de 46 a 65 años y posmenopáusicas de > 65 años, y varones de 46 a 65 años y de > 65 años) a los que se realizó DO y una encuesta sobre factores de riesgo. Se calcularon la sensibilidad, la especificidad, el VPP y el VPN de los criterios de la AETIM, y los resultados se compararon con los criterios de indicación de DO propuestos por la Organización Mundial de la Salud (en 1999 y 2003), la National Osteoporosis Foundation (en 1998 y 2010) y el Comité Internacional de Guías Clínicas en Osteoporosis. Resultados. Los criterios de la AETIM tienen una baja sensibilidad tanto para detectar baja masa ósea (índice T<−1) como osteoporosis (índice T<−2,5); la especificidad varía según el grupo. El VPP es bajo, pero el VPN para osteoporosis es alto en todos los grupos (excepto el de mujeres posmenopáusicas > 65 años). El resto de los criterios tienen un VPN alto y, en mujeres, buena sensibilidad y muy baja especificidad, especialmente para identificar pacientes con osteoporosis. Conclusiones. Los criterios de la AETIM son útiles para seleccionar pacientes a los que no sería necesario realizar una DO, pero carecen de sensibilidad suficiente para identificar individuos con baja masa ósea. El resto de criterios tienen también un VPN alto para osteoporosis y una sensibilidad algo mejor (AU)
