Guideline for the Treatment of Breakthrough and the Prevention of Refractory Chemotherapy‐Induced Nausea and Vomiting in Children With Cancer

This clinical practice guideline provides an approach to the treatment of breakthrough chemotherapy‐induced nausea and vomiting (CINV) and the prevention of refractory CINV in children. It was developed by an international, interprofessional panel and is based on systematic literature reviews. Evidence‐based interventions for the treatment of breakthrough and prophylaxis of refractory CINV are recommended. Gaps in the evidence used to support the recommendations made in this clinical practice guideline were identified. The contribution of these recommendations to breakthrough and refractory CINV control in children requires prospective evaluation.     

Osmolality of enteral formula and severity of experimental necrotizing enterocolitis

Purpose

Administration of hyperosmolar formula is regarded as a risk factor for the development of necrotizing enterocolitis (NEC). However, there are limited number of reports about the relationship between formula osmolality and NEC. The aim of this study is to evaluate the effects of formula concentration in an experimental model of NEC.

Methods

We studied experimental NEC in C57BL/6 mice. NEC was induced by giving hypoxia, gavage administration of lipopolysaccharide and gavage formula feeding from postnatal day 5–9. We used two types of formula: (1) hyperosmolar formula (HF): 15 g Similac + 75 ml Esbilac (849 mOsm/kg); (2) diluted formula (DF): dilute hyperosmolar formula with an equal amount of water (325 mOsm/kg). Controls were fed by the mother. On postnatal day 9, the ileum was harvested and evaluated for severity of mucosal injury (hematoxylin/eosin staining) and inflammation (PCR for IL6 and TNFα mRNA expression).

Results

The incidence of NEC was same in both HF and DF (80%). The intestinal inflammatory response was similar between HF and DF (IL6: p = 0.26, TNFα: p = 0.69).

Conclusions

This study indicates the osmolality of enteral formula does not affect incidence of experimental NEC. This experimental study provides new insights into the relationship between formula feeding and NEC.

     

Sequential renal and bone marrow transplants in a child with Fanconi anemia

FA is an autosomal recessive disorder characterized by small stature and renal abnormalities. FA can lead to progressive bone marrow failure, myelodysplastic syndrome, or acute leukemia. Using a multidisciplinary team approach, we managed a 3‐yr‐old boy with FA who simultaneously developed renal and hematopoietic failure. Because renal function was insufficient to support the conditioning regimen for HCT, we performed a deceased donor renal transplant in December 2012 prior to HCT with the known risk of graft‐versus‐graft rejection of the donor kidney. Seven months later he underwent allogeneic HCT. He obtained myeloid engraftment on day +11 and peripheral blood chimerism demonstrated all donor by day +21. He developed asymptomatic CMV reactivation and despite antirejection medications, mild skin graft‐versus‐host disease. He has maintained excellent renal function and remains transfusion independent with full hematopoietic recovery. He has not experienced any renal rejection episodes nor developed donor‐specific antibodies toward his renal donor. Peripheral blood chimerism remains completely HCT donor. He is clinically well, now greater than two and a half yr after renal transplant and two yr after HCT. The continuing close collaboration between the Pediatric Nephrology and Bone Marrow Transplant teams is a major factor in this successful outcome.     

Alexithymia,Coping Styles and Traumatic Stress Symptoms in a Sample of Veterans Who Experienced Military Sexual Trauma

The current study examined the association between alexithymia and coping styles (planning, positive reinterpretation and growth, social‐emotion coping, and denial), and trauma symptoms in a clinical sample of 170 male and female veterans who experienced sexual trauma during military service. Denial was the only coping style positively associated with trauma symptoms, and it mediated the relationship between alexithymia and trauma symptoms. Alexithymia was negatively associated with planning. Likewise, alexithymia was negatively associated with social‐emotional coping and with positive reinterpretation and growth. The results speak to the significant role that alexithymia has in predicting individual coping styles. Copyright © 2014 John Wiley & Sons, Ltd.
