Antibiotics for acute otitis media: a meta-analysis with individual patient data.

BACKGROUND: Individual trials to test effectiveness of antibiotics in children with acute otitis media have been too small for valid subgroup analyses. We aimed to identify subgroups of children who would and would not benefit more than others from treatment with antibiotics. METHODS: We did a meta-analysis of data from six randomised trials of the effects of antibiotics in children with acute otitis media. Individual patient data from 1643 children aged from 6 months to 12 years were validated and re-analysed. We defined the primary outcome as an extended course of acute otitis media, consisting of pain, fever, or both at 3-7 days. FINDINGS: Significant effect modifications were noted for otorrhoea, and for age and bilateral acute otitis media. In children younger than 2 years of age with bilateral acute otitis media, 55% of controls and 30% on antibiotics still had pain, fever, or both at 3-7 days, with a rate difference between these groups of -25% (95% CI -36% to -14%), resulting in a number-needed-to-treat (NNT) of four children. We identified no significant differences for age alone. In children with otorrhoea the rate difference and NNT, respectively, were -36% (-53% to -19%) and three, whereas in children without otorrhoea the equivalent values were -14% (-23% to -5%) and eight. INTERPRETATION: Antibiotics seem to be most beneficial in children younger than 2 years of age with bilateral acute otitis media, and in children with both acute otitis media and otorrhoea. For most other children with mild disease an observational policy seems justified.

Incidental finding of a large pulmonary valve fibroelastoma: a case report.

Papillary fibroelastoma (PFE) is an uncommon primary neoplasm of cardiac origin. They are solitary neoplasms that historically were an incidental finding at the time of autopsy. With the advent of two-dimensional echocardiography, symptomatic cases have been reported in current literature, thus causing a paradigm shift in the management of these tumors. Although the majority of PFE are benign, because of their potential risk for complication related to embolic and obstructive phenomena, they are now considered hazardous and require tumor excision even in asymptomatic patients. We report a case of an asymptomatic incidental large papillary fibroelastoma within the right ventricular outflow tract.

A mobile trauma database with charge capture.

BACKGROUND: Charge capture plays an important role in every surgical practice. We have developed and merged a custom mobile database (DB) system with our trauma registry (TRACS), to better understand our billing methods, revenue generators, and areas for improved revenue capture. METHODS: The mobile database runs on handheld devices using the Windows Compact Edition platform. The front end was written in C# and the back end is SQL. The mobile database operates as a thick client; it includes active and inactive patient lists, billing screens, hot pick lists, and Current Procedural Terminology and International Classification of Diseases, Ninth Revision code sets. Microsoft Information Internet Server provides secure data transaction services between the back ends stored on each device. Traditional, hand written billing information for three of five adult trauma surgeons was averaged over a 5-month period. Electronic billing information was then collected over a 3-month period using handheld devices and the subject software application. One surgeon used the software for all 3 months, and two surgeons used it for the latter 2 months of the electronic data collection period. This electronic billing information was combined with TRACS data to determine the clinical characteristics of the trauma patients who were and were not captured using the mobile database. RESULTS: Total charges increased by 135%, 148%, and 228% for each of the three trauma surgeons who used the mobile DB application. The majority of additional charges were for evaluation and management services. Patients who were captured and billed at the point of care using the mobile DB had higher Injury Severity Scores, were more likely to undergo an operative procedure, and had longer lengths of stay compared with those who were not captured. CONCLUSION: Total charges more than doubled using a mobile database to bill at the point of care. A subsequent comparison of TRACS data with billing information revealed a large amount of uncaptured patient revenue. Greater familiarity and broader use of mobile database technology holds the potential for even greater revenue capture.

Listening to young people with special needs: the influence of group activities.

The article reports on the experiences of group activities within an area of Yorkshire that helped young people with special needs to express their views and opinions. Significant issues were raised by the ethics of undertaking work with young people and these are reviewed. The young people involved in the research reported that their participation in the groups developed their self-confidence and advocacy skills. This led them to be more confident in expressing their needs at school and in the community. To establish wider generalizability for the study findings, the Yorkshire group activities were compared with another similar group in London where further data were collected from the young people involved. In facilitating group activities, willing staff were an important addition to the group because their presence provided and encouraged positive reactions to the distinctive achievements of the young people themselves. In both groups, members were committed to participation in project-based activities that raised their self-esteem and helped establish a sense of their own identity and purpose.

Mantle cell lymphoma disguised as marginal zone lymphoma.

We report a case of mantle cell lymphoma histologically indistinguishable from marginal zone lymphoma. An 83-year-old man presented with a 9.0-cm, slowly enlarging axillary mass. Microscopically, the neoplastic process was largely interfollicular, surrounding residual follicular centers, some of which had discernible small lymphocyte mantles. Overall, the morphologic pattern was highly suggestive of marginal zone lymphoma. However, flow cytometric and immunohistochemical results, including cyclin D1 positivity, revealed an immunophenotype that fit with mantle cell lymphoma. The differential diagnosis of mantle cell lymphoma is broad, and it is well known that mantle cell lymphoma can assume a number of histologic appearances, including, infrequently, that of more indolent B-cell non-Hodgkin lymphomas. Although not pathognomonic, cyclin D1 positivity is highly specific for mantle cell lymphoma and is key in distinguishing these clinically dissimilar malignant lymphomas. In recent years, detection of cyclin D1 has expanded the recognizable histologic spectrum of mantle cell lymphoma.
