OBJECTIVE To determine hearing outcomes in young children receiving early and repeated tympanostomy tube insertion for recurrent acute otitis media or otitis media with effusion. DESIGN Prospective 14-year follow-up. SETTING Central Hospital of Central Finland, a tertiary care hospital. Patients Three hundred five consecutive infants and young children with otitis media received initial tym...

background: otitis media with effusion (ome) is the most frequent indication for surgery in children. some surgeons prefer to use adenoidectomy and myringotomy with tympanostomy tubes insertion to prevent the sequelae of the disease and also more improvement of hearing. the aim of this study is to compare adenoidectomy-myringotomy with adenoidectomy-myringotomy plus tympanostomy tube in the man...

The purpose of this study was to obtain a preliminary estimate of how otitis media with effusion affects the hearing sensitivity of infants. An observer-based method was used to estimate detection thresholds for IOOOor 4000-Hz tones for infants diagnosed with otitis media by a physician and for control infants. These preliminary results suggest that otitis media with effusion produces a mild to...

B. megatherium cells were grown in various culture media, centrifuged and washed, and suspended in other culture media containing "C" or "T" phage. The per cent of infection, rate of growth, lysis, and phage production were determined. The behavior of the system depends on the culture medium in which the cells were grown and also on the culture medium in which they were mixed with phage. With t...

Aim Social media (SoMe) platforms have become leading methods of communication and dissemination of scientific information in the medical community. They allow for immediate discussion and widespread engagement around important topics. It has been hypothesized that the activity on Twitter positively correlates with highly cited articles. The purpose of this study was to analyze the prevalence a...

Most existing human mobility literature focuses on exterior characteristics of movements but neglects activities, the driving force that underlies human movements. In this research, we combine activity-based analysis with a movement-based approach to model the intra-urban human mobility observed from about 15 million check-in records during a yearlong period in Shanghai, China. The proposed mod...

BACKGROUND It is widely accepted that the passive dissemination of national clinical guidance has little or no impact on practice. OBJECTIVE To assess the impact in England of an Effective Health Care bulletin on childhood surgery for glue ear issued in 1992 and to understand the reasons for any change (or lack of change) in practice that ensued. METHOD Time series analysis of the rate of u...

This document specifies an application-level protocol (i.e., payload type) for hand-raising tools using the Real Time Protocol for Distributed Interactive Media (RTP/I). RTP/I defines a standardized framing for the transmission of application data and provides protocol mechanisms that are universally needed for the class of distributed interactive media. A hand-raising tool can support collabor...

Twitter and related social media feeds have become valuable data sources to many fields of research. Numerous researchers have thereby used social media posts for spatial analysis, since many of them contain explicit geographic locations. However, despite its widespread use within applied research, a thorough understanding of the underlying spatial characteristics of these data is still lacking...
