Skipped versus consecutive pedicle screw constructs for correction of Lenke 1 curves.

Purpose: Thoracic pedicle screws provide superior curve correction to hook and wire constructs in adolescent idiopathic scoliosis, while increasing cost. The number of implants required for best correction and outcome has not yet been determined.

Methods: We retrospectively reviewed pre- and post-operative radiographs and self-reported outcome measures in an age- and curve-matched cohort of 40 patients with Lenke I AIS who underwent selective fusions between T3/4 and L1.

Hospital readmission rates after surgical treatment of primary and metastatic tumors of the spine.

Study Design: Retrospective cohort study.

Objective: This study aimed to identify the rates and causes of unplanned hospital readmission at 30 days and 1 year after surgical treatment of primary and metastatic spinal tumors.

Summary Of Background Data: Primary spine tumors and non-spine tumors metastatic to the spine can represent complex problems for surgical treatment, but surgical intervention can provide significant patients with significant improvements in quality of life.

The increased prevalence of cervical spondylosis in patients with adult thoracolumbar spinal deformity.

Study Design: Retrospective cohort study.

Objective: To assess the concomitance of cervical spondylosis and thoracolumbar spinal deformity.

Summary Of Background Data: Patients with degenerative cervical spine disease have higher rates of degeneration in the lumbar spine.

Hospital readmission after spine fusion for adult spinal deformity.

Study Design: Retrospective cohort study.

Objective: To assess the rate, causes, and risk factors of unplanned hospital readmission after spine fusion for the treatment of adult spinal deformity.

Summary Of Background Data: Hospital readmissions in the elderly are common, and with increasing emphasis on the quality of health care, readmission rates are used to assess hospital performance.

Quality of information concerning cervical disc herniation on the Internet.

Background Context: Many Americans seek and are influenced in their decision making by medical information on the Internet. Past studies have repeatedly found information on most medical Web sites to be deficient and of low quality. Physicians must remain aware of the quality and reliability of the information available on the Internet for patient education purposes.

Uncontrolled hemorrhage in insulin-dependent diabetic rats.

Objectives: Diabetes mellitus (DM) is a known risk factor for higher morbidity and mortality after trauma. The authors tested the hypothesis that there is a difference in the response to uncontrolled hemorrhage between normal euglycemic rats and insulin-dependent diabetic rats.

Methods: Thirty-one adult male Sprague-Dawley rats were used in this study.

Progressive Gorham disease of the forearm.

Gorham's-Stout disease is a rare but potentially debilitating disease consisting of massive bone osteolysis and bone resorption associated with vascular proliferation and increased osteoclastic activity. Although it can present in a wide variety of forms, it typically involves bones formed by intramembranous ossification such as the skull, pelvis, and scapula. It can occur spontaneously or after trauma.

The effect of ethanol on uncontrolled hemorrhage in a rodent model.

Objectives: Ethanol intoxication has hemodynamic and metabolic effects after hemorrhage according to studies using fixed-volume controlled blood loss models. The authors tested the null hypothesis that after uncontrolled hemorrhage there would be no difference in the hemodynamic responses between ethanol-intoxicated (EtOH+) and nonintoxicated (EtOH-) rats.

Methods: Forty Sprague-Dawley rats were anesthetized with althesin intraperitoneally.

The validity of the OSA-18 among three groups of pediatric patients.

Objective: To compare the signs and symptoms of obstructive sleep apnea syndrome in three groups of pediatric patients; solid organ transplant recipients, healthy children, and children with leukemia; in order to examine the effects of chronic illness on the obstructive sleep apnea-18-item questionnaire and to investigate its validity as a screening tool for obstructive sleep apnea in the pediatric solid organ transplant population.

Methods: In this cross-sectional study, there were two hundred and six subjects; 46 kidney transplant recipients, 59 liver transplant recipients, 34 patients with leukemia, and 67 healthy children. Adenotonsillar enlargement was assessed by using the obstructive sleep apnea-18-item questionnaire and by performing a focused physical examination of the oral and nasal cavity at the time of the child's routine visit in either the transplant clinic, outpatient oncology center, or general pediatric clinic.
