The effect of cyproheptadine hydrochloride (Periactin®) and megestrol acetate (Megace®) on weight in children with cancer/treatment-related cachexia

Background Children with cancer frequently have associated cachexia and malnutrition. Failure to thrive affects nearly 40% of oncology patients with advanced or progressive disease. Malnutrition can erode quality of life and adversely impact disease prognosis. Appetite stimulation and increased food intake is 1 approach to combat cancer-related cachexia. Materials and Methods Cyproheptadine hydrochloride (CH), an appetite stimulant, was administered to children with cancer-associated cachexia to prevent further weight loss. All participants started CH and were evaluated for response after 4 weeks. Efficacy of megestrol acetate (MA) was evaluated in patients who did not respond to CH. Medical evaluation, weight measurements, prealbumin, and serum leptin levels were preformed at follow-up visits. Results Seventy patients were enrolled. Of the 66 evaluable patients, 50 demonstrated a response to CH (average weight gain 2.6 kg and mean weight-for-age z-score change of 0.35, P=0.001). Seven of the 16 nonresponders received MA. Six patients completed 4 weeks of MA, 5 responded (average weight gain of 2.5 kg). The most commonly reported side effect of CH was drowsiness. One patient on MA developed low cortisol levels and hyperlipidemia. Conclusions This study demonstrates that CH is a safe and effective way to promote weight gain in children with cancer/treatment-related cachexia.

Adolescent Asthma Self-Management: Patient and Parent-Caregiver Perspectives on Using Social Media to Improve Care.

BACKGROUND Self-management of asthma can now leverage new media technologies. To optimize implementation they must employ a consumer-oriented developmental approach. This study explored benefits of and barriers to improved asthma self-management and identified key elements for the development of a digital media tool to enhance asthma control. METHODS Between August 2010 and January 2011, 18 teens with asthma and 18 parent-caregivers participated in semistructured in-depth interviews to identify mechanisms for improving asthma self-management and propose characteristics for developing a digital media tool to aid such efforts. RESULTS Teens and caregivers enumerated physician-recommended strategies for asthma management as well as currently employed strategies. Both groups thought of a potential digital media solution as positive, but indicated specific design requirements for such a solution to have utility. Whereas most participants perceived mobile platforms to be viable modes to improve asthma self-management, interest in having social networking capabilities was mixed. CONCLUSIONS A digital media product capable of tracking conditions, triggers, and related asthma activities can be a core element of improved asthma control for youth. Improved asthma control will help decrease school absenteeism.

Physicians’ perceptions of mobile technology for enhancing asthma care for youth:

This study assessed physicians’ receptivity to using mobile technology as a strategy in patient care for adolescents with asthma. Understanding physicians’ perceived barriers and benefits of integrating mobile technology in adolescents’ asthma care and self-management is an initial step in enhancing overall patient and disease outcomes. We conducted in-depth interviews with second- and third-year pediatric residents and attending physicians who oversee pediatric residents in training (N = 27) at an academic medical center in the southeastern United States. We identified both benefits from and barriers to broader use of mobile technologies for improving asthma outcomes in adolescents. Resident physicians demonstrated greater readiness for integrating these technologies than did attending physicians. Prior to adoption of mobile technologies in the care of adolescent asthma patients, barriers to implementation should be understood. Prior to widespread adoption, such systems will need to be evaluated against traditional care for demonstration of patient outcomes that improve on the current situation.

Late-Presenting Left-Sided Morgagni Congenital Diaphragmatic Hernia in a 9-Year-Old Male

Congenital diaphragmatic hernias are common, primarily occurring through the foramen of Bochdalek. However, in contrast, defects through the foramen of Morgagni are much more rare. When late presentations occur, patients may be asymptomatic or may be critically ill with respiratory and gastrointestinal symptoms. In this paper, we present a 9-year-old male who presented with recurrent, vague abdominal pain, and a previously normal abdominal CT scan. Initial investigation via an abdominal radiograph demonstrated an unexpected left lower lobe abnormality. Further evaluation and management revealed this abnormality to be an unusual left-sided congenital diaphragmatic hernia that appeared through the retrosternal foramen of Morgagni, a rare occurrence.

INTRALOBAR PULMONARY SEQUESTRATION ASSOCIATED WITH A CONGENITAL PULMONARY AIRWAY MALFORMATION TYPE II

Intralobar pulmonary sequestration (ILPS) is a rare congenital malformation of the lung. It is described as a segment of lung parenchyma with normal pleura and systemic blood supply and it has poor communication with the tracheobronchial tree. Patients usually present in later childhood or adulthood with a history of recurrent pneumonias. The malformation is rarely associated with other congenital anomalies such as a congenital pulmonary airway malformation (CPAM). A CPAM is a congenital cystic lesion of the lung that presents usually in the newborn period as respiratory distress. We describe the case of a 2-month-old female who presented to the local emergency room with the initial diagnosis of pneumonia, surgical diagnosis of ILPS, and a final pathological diagnosis of ILPS with an associated CPAM.

Sleep Duration Trajectories and Systemic Inflammation in Young Adults: Results From the National Longitudinal Study of Adolescent to Adult Health (Add Health)

Study Objectives This study examines the effects of short and long sleep duration patterns in young adults on the levels of C-reactive protein (CRP), as well as the potential effect modification by sex. Methods Using data from waves III (age 18-26) and IV (age 24-32) of the National Longitudinal study of adolescent to adult health, we examined the association between sleep trajectories in young adults, and the risk of elevated high sensitivity-CRP (hs-CRP), a marker of systemic inflammation. Results Short sleep trajectories were associated with significantly elevated log-transformed hs-CRP (coefficient = 0.11, p-value .03) and with significantly higher odds of having hs-CRP levels > 3 mg/L (OR = 1.86, 95% CI 1.29, 2.67). The association was modified by sex, with the association between short sleep duration and hs-CRP limited to males. Both the continuous (coefficient 0.117, p-value = .0362) and the categorized hs-CRP (OR = 2.21, 95% CI 1.48, 3.30) were significantly elevated with short sleep durations in males, whereas no significant associations were seen in females with short sleep durations. By contrast, log hs-CRP was significantly elevated in females with long sleep durations (coefficient = 0.232, p-value = .0296), with a nonsignificant increase in the odds of having hs-CRP levels greater than 3 mg/L (OR = 1.48, 95% CI 0.75, 2.93), whereas there were no associations with long sleep duration in males. Conclusions Systemic inflammation, measured by an elevated level of hs-CRP, is seen with persistent short sleep duration in young adult men and persistent long sleep duration in young adult women.

How to Measure Secondhand Smoke Exposure in a Pediatric Clinic Setting

T here has been a recent focus to decrease environmental tobacco smoke (ETS) exposure among children, but an important obstacle to overcome is how to accurately measure ETS exposure. Standardized questionnaires are associated with a high frequency of underreporting. Cotinine, a biomarker for tobacco exposure, appears to be a more promising method to accurately detect ETS exposure, but testing is currently expensive and results are not immediately available. We conducted a study to evaluate the use of a urine dipstick to measure cotinine as an alternative to the current complex testing.
