Eating Disorders: All that a Pediatrician Should Know.

Eating Disorders are psychiatric conditions that can manifest clinically as malnutrition due to restrictive eating and weight control behaviors or obesity due to binge eating. Eating disorders such as anorexia and bulimia nervosa have peak onset during adolescence and young adulthood. This population is at the highest risk due to psychosocial changes surrounding identity development and body image that occurs during this life-stage. Though binge eating disorder and avoidant/restrictive food intake disorder are not characterized by body image overvaluation, peak onset is also during adolescence and young adulthood.

Bordetella pertussis in a four-time kidney transplant recipient: A call for immunization programs at transplant centers.

Pertussis, or whooping cough, is a highly contagious respiratory illness caused most frequently by Bordetella pertussis. Clinical presentation ranges in severity, but life-threatening illness disproportionately affects children and immunocompromised individuals. Acellular vaccines for pertussis have been available for decades, and they are recommended throughout the lifespan. A patient who had received a kidney transplant presented with respiratory distress and dry cough as manifestations of co-infection with B pertussis and Bordetella parapertussis/bronchiseptica. The goal of this case report was to highlight the importance of immunization programs at transplant centers, which are in the unique position to care for patients both with end-stage organ disease and in the post-transplant setting.

Healthy birth weight results in higher vitamin A storage in neonate piglets administered high-dose supplements.

A proposed intervention for newborn infants in countries with suspected vitamin A (VA) deficiency is to administer 50,000 IU retinyl palmitate at birth to reduce mortality risk. However, no studies have investigated birth weight effects. In this study, low birth weight (LBW; <1 kg, n = 18) and healthy birth weight (HBW) piglets (>1.5 kg, n = 18) from VA-depleted sows were dosed with 25,000 or 50,000 IU retinyl palmitate (26.2 or 52.4 µmol retinol equivalents) at birth to compare VA reserves. Blood was collected at varying times (n = 3-5/time/dose), and piglets were killed at 12 or 24 h for blood, liver, kidneys, spleen, lungs, adrenal gland, and intestinal contents. HBW piglets had significantly higher birth, death, and organ weights than LBW (P < 0.0001 for all). HBW and LBW piglets, which received VA, had higher liver and kidney VA concentrations (0.18 ± 0.09, 0.24 ± 0.10 µmol/g liver and 13.4 ± 4.1, 14.2 ± 4.5 nmol/g kidney, respectively) than controls (n = 10) (0.051 ± 0.01 µmol/g liver and 1.01 ± 0.43 nmol/g kidney) (P = 0.0061 and < 0.0001, respectively). Total liver (9.75 ± 5.16 µmol) and kidney retinol (204 ± 79.1 nmol) were higher in HBW than LBW piglets (P < 0.0001). Extrahepatic tissues, except lung, had higher VA concentration than controls (P < 0.0001). Serum retinol and ester concentrations were higher in treated than control piglets (P = 0.0028, P < 0.0001, respectively), and significantly changed during the times sampled (P = 0.022, P = 0.011, respectively). Peak serum retinyl ester concentrations, which occurred at 3 h, were higher in piglets that received 50,000 IU (4.2 ± 4.4 µmol/L) than 25,000 IU (2.7 ± 2.3 µmol/L) (P = 0.031). Regardless of dose amount, HBW piglets stored more supplemental VA than LBW piglets when administered at birth.
