Answer: B A 25-year-old male presented with an asymptomatic nodule on his forehead. It first appeared 2 years ago and gradually enlarged with time. Physical examination revealed a 13 mm x 15 mm smooth solitary skin-coloured nodule on his forehead (Fig. 1a). He also had several skin-coloured papules on his nose and over his left periocular region (Fig. 1b), oral papillomatosis on his tongue (Fig...

 Use of human milk is the preferred food substrate for neonates due to its immunologic properties and better tolerance by the immature GI tract. There is a dose-dependent correlation in the first month of life for reduction of feeding intolerance, nosocomial infection, necrotizing enterocolitis (NEC), chronic lung disease and retinopathy of prematurity compared to formula feeding. (Ronnestad, ...

We describe a clinical case involving a 62-year-old white male, diagnosed with lymphocytoma cutis (Spiegler-Fendt sarcoid) in the cephalic segment. The diagnosis was carried out by pathological study and confirmed by immunohistochemical panel: evidence of polyclonality. Phototherapy sessions were suggested as treatment (13 PUVA sessions, with an accumulated dose of 58.65 J/cm2 ). The improvemen...

In this study we appraised three new criteria for the computation of baroreflex sensitivity (BRS) using the transfer function magnitude (TFM) method, with the aim of overcoming the conventional requirement of a coherence ≥ 0.5 between arterial pressure and RR interval time series. Measurements were carried out in a sample of 44 post-myocardial infarction patients at risk of malignant arrhythmia...

Reverse causality is a common attribution error that distorts the evaluation of private actions and public policies. This paper explores implications this when decision maker acts on it therefore affects very statistical regularities from which he draws faulty inferences. Applying Bayesian-network approach Spiegler (2016) , I explore equilibrium effects certain class reverse-causality errors, i...

Nanofiltration and reverse osmosis are investigated as a possible alternative to the conventional methods of Cr(VI) removal from model water and industrial effluent. The influences of feed concentration, water recovery, pH, and the coexisting anions were studied. The results have shown that retention rates of hexavalent chromium can reach 99.7% using nanofiltration membrane (NF-HL) and vary fro...
