The Kids' Inpatient Database, reflecting 6.70 million pediatric discharges in 1997 and 7.30 million in 2000, was coupled with the US Census Bureau data and was used to elicit the epidemiology of idiopathic slipped capital femoral epiphysis (SCFE) that occurred in children 9-16 years. It was found that the overall incidence of SCFE in the United States for these years was 10.80 cases/100,000 children. The relative incidence of SCFE was 3.94 times higher in black children and 2.53 times higher in Hispanic children than in white children. The incidence rate was significantly higher in boys (13.35 cases/100,000 children) than in girls (8.07 cases/100,000 children). Higher incidence rates of SCFE were found in the Northeast and West when compared with rates in the Midwest and the South, suggesting that climate plays a role in the onset of SCFE. Increased incidence of SCFE was noted north of 40 degrees latitude during the summer and south of 40 degrees latitude during the winter. Age of onset was also lower than previously reported and seems to be on a downward trend. This study suggests that the relative incidences of SCFE in blacks and Hispanics are higher than previously reported in the United States. Geographic, racial, and seasonal variations suggest that both environmental and genetic factors may influence the development of SCFE.

Acute renal failure remains common among hospitalized patients with HIV and is associated with chronic kidney disease, liver disease, and increased mortality.

The frequency of UCL reconstruction is steadily rising in New York State and becoming more common in adolescent athletes. Emphasis on public education on the risks of overuse throwing injuries and the importance of adhering to preventative guidelines is essential in youth baseball today.

This dataset suggests that endovascular AAA repairs are being performed in a patient population with a higher frequency of comorbidities. However, endovascular repairs still are associated with significantly lower in-hospital mortality, fewer postoperative complications, and a dramatically shorter length of stay. These results suggest that, despite the rapid diffusion of this new technique, early perioperative outcomes may be superior to those with conventional open repair. However, prospective clinical studies are needed to confirm these insights, and such studies may require the infrastructure of consortia of hospitals or society-based registries.

There has been a substantial increase in the overall volume and the population-based incidence of acromioplasties in recent years on both the state and national levels in the United States. The reasons for this increase have yet to be determined and are likely multifactorial, with patient-based, surgeon-based, and systems-based factors all playing a role.

The cost of long-term LVAD implantation is commensurate with other life-saving organ transplantation procedures like liver transplantation. As an evolving technology, there are a number of opportunities for improvement that will likely reduce costs in the future.

Acute renal failure remains a common complication of nonrenal solid organ transplantation and is associated with increased mortality, prolonged hospitalization, and significant financial costs.
