The COMQ-12 questionnaire has been elaborated to evaluate the deterioration in the quality of life of the subjects suffering from chronic suppurative otitis media (CSOM) based on the reports of the patients themselves. This questionnaire is of special interest in that it allows to register the complaints of the patients stated by them in the order of priority beginning from those that are responsible for the most pronounced manifestations of the impairment in the quality of life. It, in turn, helps the medical practitioner to rationally organize the treatment of a concrete patient taking into consideration his or her individual expectations...

OBJECTIVE: The aim was to study the relationship between the labyrinthine portion (LP) of the facial canal and the cochlea in human inner ear molds and temporal bones using micro-CT and 3D rendering. A reduced cochlea-facial distance may spread electric currents from the cochlear implant to the LP and cause facial nerve stimulation. Influencing factors may be the topographic anatomy and otic capsule properties. METHODS: An archival collection of human temporal bones underwent micro-CT and 3D reconstruction...

With the aging of society, the number of elderly with reduced cognitive function has been increasing worldwide. As a test to measure the cognitive function, the Revised Hasegawa's Dementia Scale (HDS-R) has been used in Japan, Korea, and China. Since there was no HDS-R version for Laotians, the questionnaire and manual were developed through the cooperation of Lao and Japanese researchers. Back-translation was conducted to confirm the accuracy of the translation. The score on the 9-item HDS-R ranges 0 to 30 points, and reduced cognitive function is usually defined as a score of 20 points or lower...

The inner ear is composed of a complex mixture of cells, which together allow organisms to hear and maintain balance. The cells in the inner ear, which undergo an extraordinary process of development, have only recently begun to be studied on an individual level. As it has recently become clear that individual cells, previously considered to be of uniform character, may differ dramatically from each other, the need to study cell-to-cell variation, along with distinct transcriptional and regulatory signatures, has taken hold in the scientific community...

Children who are deaf and receive bilateral cochlear implants (BiCIs) perform better on spatial hearing tasks using bilateral rather than unilateral inputs; however, they underperform relative to normal-hearing (NH) peers. This gap in performance is multi-factorial, including the inability of speech processors to reliably deliver binaural cues. Although much is known regarding binaural sensitivity of adults with BiCIs, less is known about how the development of binaural sensitivity in children with BiCIs compared to NH children...

Datura metel L. is a medicinal herb that contains withasteroids and has a wide range of biological activities. We isolated 7 withasteroids from the flowers of D. metel L(1) . and examined their ability to inhibit immune responses in vitro and in vivo. Among the withasteroids, B2(2) exhibited the strongest inhibitory effect on immune responses comparing B2 with other isolated compounds from D. metel L., including suppressing the differentiation of CD4(+3) T cells by inhibiting the expression and production of T cell lineage-specific master regulators and cytokines and directly suppressing the cytokine-induced JAK/STAT(4) signaling pathways...

We have developed dual-axis optical coherence tomography (DA-OCT) which enables deep tissue imaging by using a novel off-axis illumination/detection configuration. DA-OCT offers a 100-fold speed increase compared with its predecessor, multispectral multiple-scattering low coherence interferometry (ms2/LCI), by using a new beam scanning mechanism based on a microelectro-mechanical system (MEMS) mirror. The data acquisition scheme was altered to take advantage of this scanning speed, producing tomographic images at a rate of 4 frames (B-scans) per second...

Acoustic neuroma surgery is a procedure in which a benign mass is removed from the internal auditory canal (IAC). Currently, this surgical procedure requires manual drilling of the temporal bone followed by exposure and removal of the acoustic neuroma. This procedure is physically and mentally taxing to the surgeon. Our group is working on the development of an acoustic neuroma surgery robot (ANSR) to perform the initial drilling procedure. Planning the ANSR's drilling region using preoperative CT requires expertise and takes about 35 min...

Metastatic renal cell carcinoma (RCC) involving the temporal bone is a rare entity. It is usually asymptomatic and misdiagnosis as acute otitis media, mastoiditis, and Ramsay-Hunt syndrome in early onset is not uncommon. We report a case of RCC metastasis to the postoperative temporal bone in the middle of molecular targeted therapy. A 60-year-old man presented left facial palsy with severe retro-auricular pain and he also underwent left middle ear surgery for cholesteatoma more than 30 years before and had been aware of discontinuous otorrhea; therefore, initially we speculated that facial palsy was derived from recurrent cholesteatoma or Ramsay-Hunt syndrome...
