A Rare Cause of Vitamin B12 Deficiency in the Pediatric Age.

Vitamin B12 plays an important role in DNA synthesis, hematopoiesis, and neuronal mechanisms, and its deficiency can be associated with insufficient intake or poor absorption and autoimmune and genetic diseases. Although rare, excessive, and chronic alcohol consumption may also justify a deficiency in this vitamin. We present a case of a 17-year-old Iraqi adolescent refugee in Portugal with a deficiency of vitamin B12 due to excessive and chronic alcohol consumption.

Palliative Care in Children with Inherited Metabolic Diseases: Why does it matter?

Background: Inherited metabolic diseases (IMD) bring considerable burden on the child and family. Challenging areas for health care include the identification of distressing symptoms, prognostic uncertainty, and bereavement. Literature regarding the impact of paediatric palliative care (PPC) is scarce.

Chronic pain impact on rodents' behavioral repertoire.

Rodent models have been fundamental to understand chronic pain (CP) pathophysiology and to test for potential treatments. Pain assessment in CP models is most frequently based on the evaluation of allodynia or hyperalgesia. However, these correspond only to a part of CP-related problems which include ongoing pain, depression, anxiety, disrupted sleep and attentional deficits.

High trait impulsivity potentiates the effects of chronic pain on impulsive behavior.

Preclinical studies on impulsive decision-making in chronic pain conditions are sparse and often contradictory. Outbred rat populations are heterogeneous regarding trait impulsivity manifestations and therefore we hypothesized that chronic pain-related alterations depend on individual traits. To test this hypothesis, we used male Wistar-Han rats in two independent experiments.
