Dermatofibrosarcoma protuberans en el dorso del pie: a propósito de un caso

El dermatofibrosarcoma protuberans es un tumor de partes blandas poco frecuente, de etiología desconocida y crecimiento lento. Con una incidencia de metástasis inferior al 5%, presenta una tasa de recidivas superiores al 30%. Presentamos el caso de un dermatofibrosarcoma protuberans en el dorso del pie que requirió una amplia resección del tumor y la posterior cobertura mediante colgajo pediculado libre anterolateral de muslo. El paciente se encuentra tras 4 años libre de enfermedad completamente incorporado a su actividades previasDermatofibrosarcoma protuberans is a rare tumor of soft tissue of unknown etiology and slow growth. With a lower incidence of metastasis than 5%, it has a recurrence rate more than 30% of cases. We present the case of dermatofibrosarcoma protuberans on the dorsum foot which required a wide resection of the tumor and subsequent coverage by free pedicled anterolateral thigh flap. The patient is free of illness after four years and is fully incorporated into their previous activitie

Psycho-emotional disorders as incoming risk factors for myocardial infarction with non-obstructive coronary arteries

  Background: There is an emerging field underlying the myocardial infarction (MI) with non-obstruc­tive coronary arteries (MINOCA). The aim of this study was to evaluate the impact of psycho-emotional disorders and social habits in MINOCA patients. Methods: The study included 95 consecutive patients diagnosed of MINOCA and 178 patients with MI and obstructive lesions. MINOCA patients were included when they fulfilled the three main criteria: accomplishment of the Third Universal Definition of Myocardial Infarction, absence of obstructive coronary arteries and no clinically overt specific cause for the acute presentation. Results: MINOCA patients had a higher frequency of previous psychiatric illnesses than the obstructive coronary arteries group (29.7% vs. 12.9%, p = 0.001). MINOCA patients recognized emotional stress in 75.7% of the cases, while only 32.1% of the obstructive related group did (p < 0.001). The relation­ship remained after excluding takotsubo syndrome from the analysis (26 cases, 27.4%): psychiatric diseases (27.9% vs. 12.9%, p < 0.01) and recognition of emotional stress (70.8% vs. 32.1%, p < 0.001). Social habits which could act as stress modulating showed no significant relation with MINOCA. Conclusions: Psycho-emotional disorders are related to MINOCA and they could act as risk fac­tor. This relationship is maintained after excluding takotsubo from the analysis. (Cardiol J 2018; 25, 1: 24–31

HISTORICAL RECONSTRUCTION OF HEAVY METAL CONCENTRATION IN THE GULF OF CARIACO, VENEZUELA

<div>210-Pb activity is an useful technique in environmental investigation, to determine sediments accumulation rates, geochronology, and to study metals. Its activity decline exponentially with depth, and is inversely proportional to the</div><div>sedimentation rate at non-impacted ecosystem. Dating of sediments, combined with chemical profile, allow the study of the impact events in coastal zones. In the present study, we have investigated the history of metals concentrations</div><div>and sedimentation rates of recent sediments (100 years) in the Cariaco Gulf, Venezuela (Fig. 1), an important fishery area at the Caribbean Sea, with industrial, harbor, agricultural and urban activities (Fig. 2).</div
