BACKGROUND The incidence of radiation-induced hypothyroidism (RIH) in patients with head and neck cancer is >50%. The purpose of this study was to assess the long-term efficacy of free thyroid transfer (FTT) for prevention of RIH in patients with head and neck cancer. METHODS Hemithyroid dissection was completed in 10 patients with advanced head and neck cancer undergoing ablation, radial for...

Sports-related concussion is the most common athletic head injury with football having the highest rate. Traditionally, research on the biomechanics of football-related head impacts has been focused at the collegiate level. Less research has been performed at the youth and high school level, despite undetermined rates of concussion among youth football players. The objective of this study is to...

PURPOSE To determine the timing of mitochondrial mutations in the progression of head and neck squamous cell carcinoma. EXPERIMENTAL DESIGN Twenty-three mitochondrial mutations were identified in 12 tumors using a high-throughput mitochondrial sequencing array. Areas of adjacent dysplastic and normal epithelium adjacent to tumors were sequenced using conventional methods for the presence of m...

BACKGROUND Head injuries rank high among morbidities due to trauma. Computerised tomography is an important modality in the investigation of these cases. However, literature on this subject in the south-south geopolitical zone of Nigeria is sparse. This study therefore aimed to document the computerized tomographic features of patients with head injury managed at the University of Benin Teachin...

the optimal fractionation schedule for radiotherapy of head and neck cancer has been controversial. the objective of this randomized trial was to test the efficacy of hyperfractionation vs. standard fractionation. patients with squamous cell carcinoma of head and neck organs were randomly assigned to receive radiotherapy delivered with a) standard fractionation at 2 gy/fraction/day, 5 days/week...

granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. occurrence in limbs is even rarer. these tumors account for approximately 0.5% of all soft tissue tumors. granular cell tumor can also affect other organs including skin, breast, and lungs. local recurrence and metastasis is potentially higher in m...

MEG forward problem has been solved for about 2000 dipoles placed on the brain surface using a very ®ne 3-layer realistic model of the head and the boundary element method (BEM). For each dipole, spherical models, one-layer realistic BEM models and coarser 3-layer realistic BEM models, were used to reconstruct the dipole. It was found that the localization bias induced by using a spherical mode...

The risk of Sudden Infant Death Syndrome is increased in infants sleeping with their head covered by bedding items. This study was designed to evaluate cardiac autonomic nervous controls in infants sleeping with the head covered by bedclothes. Sixteen healthy infants with a median age of 12 weeks (range 9-13 weeks) were recorded polygraphically for one night. While they slept in their usual sup...

OBJECTIVE To determine the incidence and types of head or neck trauma and headache characteristics among US Army soldiers evaluated for chronic headaches at a military neurology clinic following a combat tour in Iraq. BACKGROUND Head or neck trauma and headaches are common in US soldiers deployed to Iraq. The temporal association between mild head trauma and headaches, as well as the clinical...
