Aplicación de las nuevas tecnologías en Atención Primaria en el control del paciente con sobrepeso u obesidad y factores de riesgo cardiovascular / Application of new technologies in Primary Care to monitor overweight or obese patients with cardiovascular risk factor

El objetivo es evaluar un seguimiento telemático (web o aplicación [app]) para pacientes con sobrepeso/obesidad y otros dos factores de riesgo cardiovascular: hipertensión arterial (HTA), dislipemia, diabetes mellitus (DM), sedentarismo, consumo tabáquico. Diseño: es un estudio de intervención con asignación aleatoria al grupo intervención (web o app) y al grupo control. Emplazamiento: centros de salud rurales y urbanos, docentes y no docentes, del Sector Zaragoza I. Participantes: 261 personas con índice de masa corporal (IMC) > 25 kg/m2 y otros dos factores de riesgo. Intervenciones: seguimiento de 18 meses con puntos de corte al inicio, 1, 6, 12 y 18 meses. Las mediciones principales son peso, tensión arterial, consumo tabáquico, eventos cardiovasculares, calidad de vida y bioquímica. Resultados: el grupo control finalizó el estudio en mayor proporción (79% versus 14%). El grupo control consiguió una pérdida del 8% de la mediana de peso al año y el grupo intervención un 5%. A los 6 meses, el grupo control logró disminuir el 7% la tensión arterial sistólica y el 5% la diastólica. La hemoglobina glicosilada (HbA1c) descendió un 1% en el grupo control y un 0,5% en el grupo intervención (test de Wilcoxon: 10; p = 0,089). El colesterol de lipoproteínas de baja densidad (cLDL) del grupo control descendió 9 mg/dL, y el del grupo intervención, 7 mg/dl (test de Wilcoxon: 1.089; p = 0,018). El hábito tabáquico disminuyó en todos los grupos (test de Wilcoxon: 21; p = 0,036). El grupo control presentó mayor prevalencia de eventos cardiovasculares. La calidad de vida mejoró en todos los grupos (test Wilcoxon: 979; p = 0,041). Conclusiones: las/los pacientes que acuden al centro de salud para un seguimiento de peso consiguen mejores resultados que si el seguimiento se hace de forma telemática.(AU)

The aim was to evaluate remote assistance (Web or App) for overweight/obese patients with two extra cardiovascular risk factors: hypertension, dyslipidemia, diabetes, smoking, sedentary lifestyle. Design: intervention study using random assignment for Web Group and App Group. The App Group was subsequently selected. Location: urban and rural health centres, teaching and non-teaching centres, in the Zaragoza I health area. Subjects: 261 people with BMI> 25 Kg/m2 and two extra cardiovascular risk factors. Interventions: 18 months follow up, initial checkups and after 1, 6, 12 and 18 months. The primary endpoints were: weight, blood pressure, tobacco consumption, cardiovascular events, quality of life and blood tests. Results: The control group completed the study in a higher proportion (79% vs 14%). The control and intervention groups attained a loss of 8% in and 5% median weight per year, respectively. After 6 months, the control group managed to reduce systolic and diastolic blood pressure by 7% and 5%, respectively. Glycosidic haemoglobin was 1% and 0.5% lower in the control and intervention groups, respectively (Wilcoxon Test=10; P= 0.089). Both groups reduced tobacco consumption (Wilcoxon=21; P=0.03). The control group had a higher prevalence of cardiovascular events. Quality of life improved (Wilcoxon Test=979; P=0.041). Conclusion: Patients visiting health centres to monitor weight obtain better results than those remotely assisted.(AU)

Extranodal natural killer/T-cell lymphoma, nasal type: a Spanish multicentric retrospective survey.

BACKGROUND: Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is an aggressive lymphoma with a very low incidence in western populations. OBJECTIVE: To review the clinicopathological features and outcome of a multicentre series of ENKTL in Spain. MATERIALS & METHODS: A multicentre retrospective study was performed based on cases of ENKTL, collected from 1995 to 2004, from 12 dermatology departments included in the Spanish Lymphoma Study Group. The clinical, histopathological, and evolutive features of all these cases were reviewed. RESULTS: Eighteen patients (three male, 15 female) with median age of 67 years were included in the study. The onset of lesions occurred in the nasal region in 11 patients and on the skin outside this region in the remaining cases. The observed lesions were clinically heterogeneous, corresponding to papules, plaques, and nodules, with or without ulceration. All patients except four received different polychemotherapy regimens, either alone (n = 11) or in combination with radiotherapy (n = 4). After a variable follow-up period (1-36 months), only two patients remained alive. One patient was recently diagnosed (four months ago) with ENKTL in the nasal region and the other presented with skin-limited disease. The median overall survival was 9.5 months. CONCLUSIONS: The results of this retrospective survey confirm that ENKTL is a rare subtype of lymphoma in the Spanish population. All patients showed an aggressive clinical course and poor prognosis, regardless of the initial clinical presentation. Prospective data on larger series of patients treated homogenously are needed to establish the best treatment modality.

Epithelial-to-mesenchymal transition in penile squamous cell carcinoma.

PURPOSE: Epithelial-to-mesenchymal transition is a phenomenon in epithelial tumors that involves loss of intercellular adhesion, mesenchymal phenotype acquisition and enhanced migratory potential. While the epithelial-to-mesenchymal transition process has been extensively linked to metastatic progression of squamous cell carcinoma, studies of the role of epithelial-to-mesenchymal transition in squamous cell carcinoma containing high risk human papillomaviruses are scarce. Moreover, to our knowledge epithelial-to-mesenchymal transition involvement in human penile squamous cell carcinoma, which can arise through transforming HPV infections or independently of HPV, has not been investigated. We evaluated the presence of epithelial-to-mesenchymal transition markers and their relationship to HPV in penile squamous cell carcinoma. MATERIALS AND METHODS: We assessed the expression of E-cadherin, vimentin and the epithelial-to-mesenchymal transition related transcription factors Twist, Zeb1 and Snail by immunohistochemical staining in 64 penile squamous cell carcinoma cases. HPV was detected by polymerase chain reaction amplification. RESULTS: Simultaneous loss of membranous E-cadherin expression and vimentin over expression were noted in 43.5% of penile squamous cell carcinoma cases. HPV was significantly associated with loss of membranous E-cadherin but not with epithelial-to-mesenchymal transition. Recurrence and mortality rates were significantly higher in cases showing epithelial-to-mesenchymal transition. CONCLUSIONS: Our findings indicate that in penile squamous cell carcinoma epithelial-to-mesenchymal transition is associated with poor prognosis but not with the presence of HPV.

Chronic scalp ulceration as a late complication of fluoroscopically guided cerebral aneurysm embolization.

Fluoroscopy-induced chronic radiation dermatitis resulting from prolonged exposure to ionizing radiation during interventional procedures has been documented in the medical literature. However, this condition often requires a high clinical suspicion in order to establish a correct diagnosis. In this report, the development of deep scalp ulceration with bone exposure following the endovascular coiling of an anterior communicating artery aneurysm 8 years before is described. A skin biopsy specimen demonstrated changes consistent with chronic radiation dermatitis and ruled out malignancy. This case report expands the clinical manifestation spectrum of fluoroscopy-induced chronic radiation skin injury and highlights the importance of recognizing these lesions early to prevent morbidity related to radiation-induced skin damage.

Cutis laxa-like mycosis fungoides.

Mycosis fungoides is the most common form of primary cutaneous T-cell lymphoma. Several clinical and clinicopathological variants of mycosis fungoides have been reported. A 75-year-old woman presenting with multiple ill-defined areas of marked cutaneous wrinkling on the trunk and extremities is reported. Histopathological examination showed characteristic features of mycosis fungoides along with an interstitial dermal infiltrate composed predominantly of atypical lymphocytes with histiocytes intermingled within the collagen bundles. A focal reduction and fragmentation of elastic fibers was demonstrated. This observation illustrates a peculiar and previously unreported clinicopathological presentation of mycosis fungoides: cutis laxa-like mycosis fungoides, expanding the spectrum of mycosis fungoides variants associated with abnormalities of the dermal elastic fibers.

Control y vigilancia en fronteras. Papel de sanidad exterior durante las fases de contención de la pandemia (H1N1) 2009 / Health control at international borders. The role of foreign health during the containment phases of the Pandemic (H1N1) 2009

Los controles sanitarios en fronteras, establecidos con el objeti-vo de retrasar la entrada del virus pandémico en España, constituyen una de las actividades propias de las fases de contención de la enfer-medad. Su puesta en práctica como estrategia de salud pública en respuesta a epidemias es responsabilidad de la Dirección General de Salud Pública y Sanidad Exterior del Ministerio de Sanidad y Políti-ca Social, a través de la Subdirección General de Sanidad Exterior, y para ello se requiere una actuación coordinada con otros organismos implicados. Este trabajo tiene como finalidad describir las actuaciones reali-zadas en los aeropuertos internacionales durante dichas fases, así como evaluar su efectividad en la consecución del objetivo para el que fueron diseñadas. En este sentido, se establece una hipótesis que trata de explicar cómo las medidas adoptadas por Sanidad Exterior y la colaboración con los Servicios de Vigilancia Epidemiológica de las Comunidades Autónomas podrían haber contribuido a retrasar la propagación del virus en nuestro país. Se destaca la necesidad de consolidar los sistemas de vigilancia en fronteras potenciando dicha colaboración, así como la importan-cia de diseñar una estrategia clara de comunicación a la población en estos escenarios, que debe acompañar a la implementación de las demás medidas para evitar situaciones de incertidumbre(AU)

As a public health strategy in responding to epidemics, sanitary checks at borders to delay the entry of the pandemic virus into Spain are part of the containment phases activities. Their implementation is the responsibility of the Foreign Health Department and requires a coordinated action with other agencies involved in the response. This paper describes the actions undertaken at international air-ports during these phases and evaluates its efficacy in the execution of their objective. We establish a hypothesis to explain how the mea-sures undertaken by Foreign Health and the collaboration with the National Surveillance System may have contributed to delay the spread of the virus into our country. We want to emphasize the need for consolidating the border con-trol surveillance system and improving collaboration, as well as the importance of designing a clear communication strategy for the population in these settings. Together these measures, along with others, will prevent situations of uncertainty(AU)

Dermoscopic and reflectance confocal microscopic features of exogenous ochronosis.

BACKGROUND: Exogenous ochronosis presents as an acquired asymptomatic hyperpigmentation on photoexposed areas, predominantly over bony prominences, and is caused by the topical application of several skin-lightening agents. OBSERVATIONS: We describe a 63-year-old Hispanic woman who developed exogenous ochronosis lesions on her face after using topical bleaching creams containing hydroquinone, 2% to 3%, and oxybenzone, 2%, for several years. Dermoscopy revealed irregular brown-gray globular, annular, and arciform structures that corresponded to focal deposition of ochronotic pigment on the dermis. These deposits correlated with multiple banana-shaped nonrefractile structures seen using reflectance confocal microscopy. Histopathologic sections revealed the deposition of a banana-shaped, yellow to brown material in the papillary and middle dermis. Ultrastructural examination revealed an amorphous electron-dense material mostly located in the core of elastic fibers and also in smaller amounts in the interstitium with prominent degenerative changes in the elastic fibers. A good correlation was observed between the results of both noninvasive techniques and the diagnostic histologic features of this condition. CONCLUSIONS: We characterized by means of dermoscopy, reflectance confocal microscopy, and electronic microscopy a case of exogenous ochronosis. To our knowledge, this is the first description of reflectance confocal microscopic findings in this condition. Dermoscopy and reflectance confocal microscopy are proved to be useful noninvasive techniques for the diagnosis of this pigmentary disorder.
