Abstract

There are numerous causes, such as environmental factors, medications, endocrine disorders, and genetic factors, that can lead to obesity. However, severe early-onset obesity with abnormal feeding behavior, mental retardation, dysmorphic features, organ-specific developmental abnormalities, and endocrine disorders suggest a genetic etiology. Mutations in genes related to the leptin-melanocortin pathway play a key role in genetic obesity. This pathway controls hypothalamic regulation of food intake. A few cases have been reported to have mutations in leptin (LEP) or leptin receptor (LEPR) genes. The cases had severe early-onset obesity, hyperphagia, and additional features, such as altered immune function, hypogonadism, and hypothyroidism. We present a 3-year-old male patient with severe early-onset obesity whose genetic analysis revealed a homozygous, novel, and pathogenic variant (c.1603+2T>C) in LEPR.

Verbände und Cremes gegen Dekubitus: „Wir wissen nicht, was sie bringen!“

Die Datenlage zur Wirksamkeit von Verbänden oder topischen Mitteln zur Prävention von Druckgeschwüren sei schlecht, so die Verfasser einer aktuellen Cochrane-Studie. Letztlich bleibe es unsicher, ob solche Maßnahmen den Betroffenen nutzen oder schaden.

Schützt das tägliche Glas Milch vor Darmkrebs?

Die Milch machts – sie bietet Frauen nach Daten einer großen Ernährungsanalyse den besten Darmkrebsschutz aller Lebensmittel, was am hohen Kalziumgehalt liegen dürfte. Am anderen Ende des Spektrums steht der Alkoholkonsum: Das Glas Wein am Abend ist eher ungünstig.

Vorsicht mit Glukokortikoiden bei Glomerulopathie

Auch niedrig dosierte Glukokortikoide zur Behandlung einer primären Glomerulopathie lassen offenbar die Infektionsgefahr steigen. In einer US-Studie hing das Risiko vor allem mit der kombinierten Anwendung von Immunsuppressiva zusammen.

KI-gestütztes Mammografiescreening überzeugt im Praxistest

Mit dem Einsatz künstlicher Intelligenz lässt sich die Detektionsrate im Mammografiescreening offenbar deutlich steigern. Mehr unnötige Zusatzuntersuchungen sind laut der Studie aus Deutschland nicht zu befürchten.
