Atp1a2 and Kcnj9 Are Candidate Genes Underlying Sensitivity to Oxycodone-Induced Locomotor Activation and Withdrawal-Induced Anxiety-Like Behaviors in C57BL/6 Substrains.

Opioid use disorder is heritable, yet its genetic etiology is largely unknown. C57BL/6J and C57BL/6NJ mouse substrains exhibit phenotypic diversity in the context of limited genetic diversity which together can facilitate genetic discovery. Here, we found C57BL/6NJ mice were less sensitive to oxycodone (OXY)-induced locomotor activation versus C57BL/6J mice in a conditioned place preference paradigm.

Multicentric Reticulohistiocytosis.

A Caucasian woman in her twenties having asymptomatic papules on the hands for the past 6 months was referred by rheumatology for a skin biopsy. The patient had presented to rheumatologist for arthralgia. On physical examination, multiple, dull red, 2-5-mm papules were observed on her dorsal fingers, with most in the periungual regions.

Antibiotic over-administration in hospitalized infants with Adenovirus infection.

Background: Infection with Adenovirus in children may clinically resemble a bacterial infection in several aspects, including high and prolonged fever, and increased inflammation markers. We aimed to estimate the rate of antibiotics administration among hospitalized infants with Adenovirus infection and to evaluate its justification.

Methods: Included were hospitalized patients aged 2 months - 2 years who found positive for Adenovirus in PCR tests (Ct <36).
