Development of a Regionalized,Comprehensive Care Network for Pediatric Sickle Cell Disease to Improve Access to Care in a Rural State

Sickle cell disease (SCD), an inherited group of blood disorders, is a major public health problem worldwide. Patients experience severe anemia, increased risk of life-threatening infections, painful crisis, and chronic organ damage. Access to comprehensive care for SCD is known to improve outcomes; however, it is only reported from large urban centers serving one metropolitan area. Alabama, US, is a largely rural state with a significant number of children born each year with SCD. Prior to the development of our regional clinic network, the Children and Youth Sickle Network (CYSN^SM), 50% of patients identified by newborn screening were not enrolled in comprehensive sickle cell care. The majority of non-enrolled patients lived in southern Alabama. Rural areas in this region are particularly plagued by poverty and poor access to healthcare. Life expectancy is equivalent to residents of Sri Lanka. This area has 15.7 doctors/10 000 residents compared with the statewide ratio of 41.9 doctors/10 000 residents.To improve access to care, a regional clinic network, the CYSN^SM, was established in 1995. This paper reviews the impact of the CYSN^SM on pediatrie SCD in Alabama over the first 5 years of implementation.Since its inception in 1995, the CYSN^SM has provided care for 923 patients compared with 450 prior to the development of the clinic network. Currently, 90% of all cases identified by newborn screening are enrolled compared with 50% pre-CYSN^SM. Prior to the network, the average age of patients at their first clinic visit was 21 months. In the post-CYSN^SM period, the average age at first clinic visit decreased substantially to 5.3 months. Prior to the CYSN^SM, patients traveled on average 90 miles to a comprehensive clinic. Post-CYSN^SM, this distance has been cut in half to an average of 45 miles. A total of 70% of patients now live within 30 miles of a clinic. Most importantly, the infection death rate has decreased from 5.71 deaths/100 patient years to 1.94 deaths/100 patient years.The development, implementation, and evaluation of the CYSN^SM show that comprehensive care delivery in a rural setting is feasible and improves outcomes in pediatric SCD.     

Preservice early childhood students' perceptions of written feedback on their essays

Lecturer feedback on students' essays is important to the quality of the experience students have at university (Norton & Norton, 2001). The aim of the present study was to investigate whether early childhood students at one university actually read lecturer feedback on their essays and, if they did, what they found helpful and not helpful to their learning. Feedback was defined as 'giving students information on how well or how poorly they are doing in their academic work' (Hounsell, 1987, p. 109). Using the Vygotskian concept of learning as a socially shared activity, qualitative data were collected from second-year students from a four-year early childhood degree programme via an anonymous survey and four focus groups. Major findings were that, in contrast with studies of students in other programmes, early childhood students read lecturer feedback on their essays and used feedback that was detailed and explanatory as a learning tool. Types of feedback students found to be most and least useful were identified.     

Severe influenza B myocarditis and myositis.

OBJECTIVE: To report an influenza B infection with associated myocarditis and severe skeletal myositis. DESIGN: Case report. SETTING: Cardiac intensive care unit in a university-affiliated children's hospital. PATIENT: A 4-yr-old girl. RESULTS: The patient was successfully supported with extracorporeal membrane oxygenation for profound myocardial dysfunction and a combination of plasmapheresis and continuous venovenous hemodialysis for rhabdomyolysis and acute renal failure. CONCLUSIONS: This case provides a reminder that patients presenting with viral illness or myoglobinuria accompanied by renal failure, with or without associated myocarditis, may be demonstrating symptoms of influenza B.     

MR imaging of the neonatal brain at 3 Tesla

3 Telsa MR scanners are now becoming more widely available and 3 Telsa is likely to become the filed strength of choice for clinical imaging of the brain. The neonatal brain can be safely and successfully imaged at 3 Telsa. The improved signal to noise afforded by a higher field strength may be used to improve image quality or shorten acquisition times. This may be exploited for conventional T1 and T2 weighted imaging and also for advanced techniques such as diffusion tensor imaging, angiography and functional magnetic resonance studies.
