Background: Patients with Thoracolumbar Injury Classification and Severity (TLICS) score of 4 fall into a gray zone between surgical and conservative management. The integrity of posterior ligamentous complex (PLC) evaluated by magnetic resonance imaging (MRI) contributes to surgical decision-making. Load-sharing classification (LSC) may provide a modifier to further guide decision-making in these patients.

Intraoperative middle ear effusion (MEE) is a risk factor for future BMTs in children with recurrent acute otitis media (RAOM). However, the impact of the type of MEE is unknown.

This study shows that the mentioned probes tend to compromise their accuracy and trending stability at lower NO of <1.0 mg N/L, which if used as a measuring variable for PI feedback controller for denitrification (biological reduction of nitrate to nitrogen gas), would cause overfeeding the external carbon source.

Despite extensive research and clinical trials over the past 50 years, very little progress has been made to significantly alter its lethal prognosis. The current standard of care (SOC) includes maximal surgical resection, radiation therapy and chemotherapy and temozolomide (TMZ), including the selective use of glucocorticoids for symptom control.

Rats received (intraperitoneally) one 75 mg/kg dose (Acute-1 and Acute-2 groups), three 25-mg/kg doses 1 hour apart (Repeated group), or nine single daily ketamine doses of 75 mg/kg followed by a 24-h washout period (Chronic group). Following euthanasia, all animals decomposed to skeleton outdoors.

Methods: Patients age 65 or older admitted for the first time with head injury (ICD-9 800-804 or 850-854) during 1999 were identified in a complete national sample of fee-for-service Medicare hospitalization and denominator data.
