Introduction: In order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. One of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its origina...

BACKGROUND The severity and course of spinal pain is poorly understood in adolescents. The study aimed to determine the prevalence and two-year incidence, as well as the course, frequency, and intensity of pain in the neck, mid back, and low back (spinal pain). METHODS This study was a school-based prospective cohort study. All 5th and 6th grade students (11-13 years) at 14 schools in the Reg...

S ometimes when a child is sick or hurt, it is necessary for physicians to do a procedure. The purpose of some procedures is to get more medical information; examples include doing a blood draw using a needle or collecting urine through a plastic tube called a catheter that goes into your child’s urethra. The purpose of other procedures is for a treatment, such as putting in stitches for a cut ...

We formulate a conjecture that arithmetic locally symmetric manifolds have simple homotopy type, and prove it for the non-compact case. More precisely, we show that, for any symmetric space S of noncompact type without Euclidean de Rham factors, there are constants α = α(S) and d = d(S) such that any non-compact arithmetic manifold, locally isometric to S, is homotopically equivalent to a simpl...
