Anterior cruciate ligament reconstruction in adolescents with open physes

The purpose of this study was to evaluate anterior cruciate ligament reconstructions performed in adolescents with open physes and a skeletal age of at least 14 years. At one center, from 1992 to 1996, 19 adolescents (ages, 11 to 15 years) with open physes and a skeletal age of at least 14 years underwent arthroscopic anterior cruciate ligament reconstruction using an Achilles tendon allograft placed through drill holes across the open physes in both the distal femur and proximal tibia. Fifteen patients returned for reevaluation at an average of 25 months postoperatively (range, 12 to 60 months); the remaining four patients were interviewed by telephone. There were no significant leg-length discrepancies or angular deformities as determined by scanograms and anteroposterior and lateral radiographs of the femur and tibia. The mean Lysholm knee score was 97 (range, 94 to 100) and the mean KT-1000 arthrometer side-to-side difference at 20 pounds of anterior force was 1.7 mm (range, 0.0 to 3.0). All patients were satisfied with the results of surgery, and 16 of 19 patients returned to the same sport they were participating in before the injury. This study demonstrates that anterior cruciate ligament reconstruction using an Achilles tendon allograft is a viable treatment option for skeletally immature patients with a skeletal age of 14 years who have sustained midsubstance tears of the anterior cruciate ligament.     

A comparison of Rasch with Likert scoring to discriminate between patients' evaluations of total hip replacement surgery

The purpose of this study was to examine whether there are advantages in terms of outcome assessment of using Rasch methods of scoring the 12-item Oxford Hip Score (OHS) questionnaire over conventionally Likert scores. As part of a prospective cohort study of total hip replacements in five former regions of England the OHS was sent to patients pre-operatively, at 3 months and 1 year post-operatively. Post-operative data was collected on over 5000 cases. Based on the level of satisfaction with surgery, patients were divided into satisfied and dissatisfied. Analyses were performed to test the relative precision (RP) of Rasch scoring vs. conventionally Likert scores in discriminating the groups experiencing different level of satisfaction. Considerable gains in precision were achieved with Rasch scoring methods when groups were compared 3 and 12 months post-operatively. The results from the current study suggest that in some situations there may be substantial gains in measuring health related outcomes using Rasch-based scoring methods.     

A Different Kind of Christmas Tree: Anomalous Origin of the Right Coronary Artery from the Pulmonary Artery (ARCAPA)

Anomalous right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly that has an incidence of 0.002%. We report a case of a previously healthy female who presented to our hospital with pneumonia and was incidentally discovered to have ARCAPA. This was initially diagnosed on echocardiography by the unusual echocardiographic finding of multiple color flow Doppler signals around the right ventricular free wall and apex which were subsequently confirmed by angiography to be due to extensive collateral circulation between the left and right coronary arteries. This represents an unusual echocardiographic manifestation of this very rare condition.     

Coronary Artery Disease in Patients ≥80 Years of Age

Coronary artery disease (CAD) is a major cause of morbidity and mortality in patients ≥80 years of age. Nonetheless, older patients have typically been under-represented in cardiovascular clinical trials. Understanding the pathophysiology, epidemiology, and optimal means of diagnosis and treatment of CAD in older adults is crucial to improving outcomes in this high-risk population. A patient-centered approach, taking into account health status, functional ability and frailty, cognitive skills, and patient preferences is essential when caring for older adults with CAD. The present systematic review focuses on the current knowledge base, gaps in understanding, and directions for future investigation pertaining to CAD in patients ≥80 years of age.     

Overweight and Obesity Among Hawai‘i Children Aged 4 to 5 Years Enrolled in Public Schools in 2007–2008 and Comparison with a Similar 2002–2003 Cohort

This assessment provides the most recent estimates of overweight and obesity among children 4 to 5 years old who were enrolled in public schools in the 2007–2008 school year, using data obtained from Student Health Records for 12,823 children, which represents 91% of the 14,070 children who were enrolled in kindergarten in 2007–2008. This assessment is a census of 4 to 5 year olds that entered public schools in Hawai‘i in 2007–2008 and represents approximately 38% of the total Hawai‘i population for those aged 4 to 5 years, since kindergarten is not a requirement. A limited data set with data on age, sex, height, and weight was used to calculate BMI (body mass index) percentiles. We compare this data with age and sex-specific BMI obtained from Student Health Records from 10,199 children aged 4 to 5 years entering public schools during 2002–2003. The results illustrate that like the 2002–2003 data (28.5%), over one in four (28.6%) of the children aged 4 to 5 years entering Hawai‘i public schools in 2007–2008 were either overweight or obese. Total proportions overweight and obese were persistently higher (32.5% or more in both 2002–2003 and 2007–2008) in some specific school complexes on O‘ahu as well as in some rural and Neighbor Island school complexes. Physicians, public health and school health professionals, advocates, schools, and communities should be vigilant about this persistent problem and seek to implement practices to combat overweight and obesity. In addition, the use of Student Health Records for on-going pediatric obesity surveillance should be explored more fully.
