BACKGROUND This study describes epidemiological data of non-Hodgkin's lymphoma (NHL) diagnosed from 2001 to 2008 among Saudi men. MATERIALS AND METHODS Retrospective data from all NHL cancer cases among Saudi men recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008 were used. Descriptive statistics, analysis of variance, Poisson regression, and simple linear regr...

BACKGROUND Patients with unilateral sensorineural hearing loss (USNHL) experience great difficulty listening to speech in noisy environments. A directional microphone (DM) could potentially improve speech recognition in this difficult listening environment. It is well known that DMs in behind-the-ear (BTE) and custom hearing aids can provide a greater signal-to-noise ratio (SNR) in comparison t...

he risk of infection is generally based on the susceptibility of a surgical wound to microbial contamination. Clean surgery carries a 1-5% risk of postoperative wound infection, and in dirty procedures that are significantly more susceptible to endogenous contamination, 27% risk of infection has been estimated.1 The Guideline for Prevention of Surgical Site Infection, 1999 issued by the Centers...

A digital measurement method for lowinvasive clinical diagnosis of metallic prosthesis osseointegration was proposed. Electrical impedance spectroscopy is exploited to characterize the quality of the interface bone-prosthesis tissue. In this paper, in vitro and in vivo experimental results of the application of the proposed method to the evaluation of osseointegration of metallic implants used ...

The photophysics and photochemistry of the β-lapachone derived diphenyldihydrodioxin 3 were investigated using steady-state and time resolved techniques. Laser excitation of 3 leads to the formation of its cation radical 4 (absorption maxima at 410 and 450 nm and a lifetime of 10 μs), which was confirmed by its thermal generation employing tris(2,4-dibromophenyl)-aminium hexachloroantimonate (B...

Bone anchored hearing implants/aids (BAHI/BAHA) utilise a bone anchored hearing aid system to assist people with conductive hearing loss who cannot use traditional hearing aids. It was introduced in the 1970 ́s in the field of dentistry by Swedish Professor Per-Inge Brånemark who implanted titanium dental fixtures in the jaw. He then proceeded to develop titanium implants to anchor hearing aids ...

OBJECTIVES To assess complications occurring in patients with a bone-anchored cochlear stimulator (Baha) following split-thickness skin graft harvested with two surgical modalities: the TriVerse (TV) system and the molecular resonance generator (MR). STUDY DESIGN Prospective, randomized, two-group (TV and MR) study of 24 patients who underwent Baha surgery. SETTING Tertiary care institution...

OBJECTIVE To evaluate the sound localization capabilities of patients with unilateral, profound sensorineural hearing loss who had been treated with either a bone-anchored hearing device (Baha BP100) or a TransEar 380-HF bone-conduction hearing device. STUDY DESIGN Nonrandomized, prospective study. SETTING Tertiary referral private practice. PATIENTS Patients with unilateral, profound senso...
