Bilateral occlusion of the middle cerebral artery (MCA) trunk theoretically should be a very severe condition, but its actual prognosis has never been studied. Nine of 1,377 patients (7 Asians, 1 Black, 1 Caucasian) from the Cooperative Study of Extracranial/Intracranial Arterial Anastomosis were found to have atherosclerotic bilateral occlusion of the middle cerebral artery (MCA) trunk before ...

OBJECTIVE Otitis media with effusion (OME) is a condition in which fluid is retained in the middle ear cavity. The association between endocrine disorders and OME has not yet been determined. This study aimed to investigate the presence of OME in children diagnosed with an endocrine disease and the relationship between these two conditions. METHODS The study was conducted on 918 pediatric pat...

The increasing emergence and spread of antimicrobial resistance (AMR) is a serious public health issue. Increasing the awareness of the general public about appropriate antibiotic use is a key factor for combating this issue. Several public media campaigns worldwide have been launched; however, such campaigns can be costly and the outcomes are variable and difficult to assess. Social media plat...

1994). Theoretically, early compromise of speech perception could, therefore, adversely affect phonologic awareness as well as oral and written language skills. As Johnson et al. (this issue) point out in their review of the literature, some have argued (Eimas & Clarkson, 1986) that persistent middle ear effusion, which can cause partial and intermittent impairment of hearing, can pose a threat...

Background: The aim of the study was to analyze the performance of PCR-DGGE based assay and its applicability as a tool for the identification of bacteria in the middle ear of children with otitis media with effusion (OME). Methods: The middle ear effusions from 20 children with OME were analyzed both by bacterial culture and by 16S rDNA-gene-targeted PCR assay, DGGE fingerprinting and sequenci...

BACKGROUND Middle ear effusion (MEE) is rare among adults, but has a higher incidence among ICU patients. The aim of this study was to analyze the effect of nasogastric tube (NGT) on MEE and to assess other predisposing factors. METHODS Prospective observational study, carrying out an otoscopic examination and tympanometry in 100 mechanically ventilated patients. Immittance testing was carrie...

Acute otitis media (AOM) is a multifactorial disease with a significant socioeconomic impact. The pathogenesis of AOM is attributed to a variety of well-established internal and extrinsic factors. Recent evidence strongly points to bacterial biofilm formation as an important contributor to this disease entity. The nasopharynx is a likely reservoir for infection with subsequent seeding of pathog...

In this study, the effect of cladded tungsten carbide layer upon HSS - M2 tool steel on microstructure, hardness, and wear behavior has been studied in two cases without using the middle layer and using the middle layer of nickel. Tungsten Carbide cladded on HSS - M2 tool steel by Arc Weld ( SMAW ). The ASTM-G65 wear test was used to determine its application for use in the mineral indus...

Wideband middle ear power (WMEP) measurement is a method of middle ear analysis that may provide improved diagnostic capability over single-frequency tympanometry. However, normative data, information about test-retest reliability, and results in clinical disorders are needed for clinical application. Normative and reliability data on WMEP in children three days to 47 months of age were obtaine...
