AIM The elderly are the major population receiving the implantation of a permanent pacemaker (PPM). Infection is a devastating complication. The present study is to verify the relationship between age and PPM implantation infection. METHODS All patients (162 adult and 292 elder patients) received the implantation of PPM. Subcutaneous tissue samples solution was collected in three time points,...

Cochlear implantation is a common surgical procedure for children with profound hearing loss who receive minimal or no benefit from traditional hearing aids. Cochlear implants bypass the damaged portion of the inner ear by providing direct electrical stimulation to the auditory nerve. This electrical stimulation attempts to simulate hearing and is highly successful in many children. However, pr...

objectives: profound hearing loss encounters children with delay in speech and language. as it is known language acquisition in young deaf children is a lengthy process, but cochlear implanted children have better spoken language skills than if they had not received the device. according to the importance of cochlear implant in deaf child's language development, this study evaluates the ef...

PURPOSE To objectively compare the optical quality and the intraocular scattering after implantation of the posterior chamber phakic implantable collamer lens (Visian ICL™, STAAR Surgical) with and without a central artificial hole for moderate to high ametropia. METHODS This retrospective study comprised 28 eyes of 28 consecutive patients undergoing Hole ICL implantation (mean age ± standard...

INTRODUCTION Cochlear implantation can facilitate the development of communication skills in children with profound hearing loss. The objectives of our study were to determine the average ages at suspicion and diagnosis of hearing loss, amplification, intervention, and performing the cochlear implantation and to investigate the effects of the parents' level of education and economic circumstanc...

IMPORTANCE This study reviewed whether advanced age should be a consideration when revision cochlear implantation is warranted. OBJECTIVE To examine whether age at revision cochlear implantation is related to postrevision speech perception performance. DESIGN, SETTING, AND PARTICIPANTS A retrospective analysis was performed in an academic tertiary care center. Participants included 14 young...

background: the emotional changes of patients undergoing cochlear implantation (ci) has been addressed in a few studies. to date, no special test has been developed to measure these changes .   objective: to measure the emotional status of children undergoing ci by interpreting their drawings.   methods : a prospective longitudinal study on prelingually deafened children from 4-14 years of age ...

background: anterior interbody fusion of the cervical spine have become the gold standard for treating spinal diseases, hence the aim of this study was to compare long term follow up results in patients with cervical disk disease treated with anterior peek cage implantation and without it in anterior approach. methods: retrospectively 63 patients with known cervical discogenic disorders who wen...

To determine the incidence and extent of calcification of implanted glutaraldehyde-treated porcine prosthetic heart valves, 82 valves explanted from 73 patients were examined for calcium by radiography and light microscopy. At the time of valve implantation, the patients were 21⁄4/4-76 years old. They included 15 children (patients younger than 15 years of age, mean age at time of valve implant...
