Wrist fractures are common injuries in musicians, and a number of these fractures heal in a mal-united position, interfering with wrist rotation. This can prevent musicians who play keyboard instruments and the smaller string instruments from assuming the required wrist positions. Resection of the distal ulna (Darrach procedure), while somewhat discredited for the general population, has proved to be the ideal operation for this problem in musicians and has been used successfully on five professional musicians. This procedure, the rationale for its use in musicians, and the important technical details are discussed.

Summary Using an approach based on the sociology of quantification, this article illustrates how actors utilised statistics when importing family planning to Taiwan and exporting their experience to international policy makers. The functions of statistics—producing knowledge and making policies—assisted the implementation of international programmes in Taiwan, where any actions leading to a population decrease were prohibited in the 1950s. The Population Council and Taiwanese officials first secured the provincial government’s tacit consent by claiming the programme to be an experiment in general population policy rather than one focused on the insertion of intra-uterine devices (IUDs). They went on to win the central government’s endorsement in 1964 by presenting IUD insertions as tools for achieving the ideal population size for economic development. Finally, experts packaged and repackaged the Taiwan programme as a success by wielding locally-collected statistics, reframing the programme to fit the conclusions of international research at the time.

AIM: To investigate the impact of tinnitus on professional musicians in the UK. BACKGROUND: Tinnitus is the experience of sound when an external source is absent, primarily associated with the ageing process, hearing loss, and noise exposure. Amongst populations exposed to industrial noise, noise exposure and noise-induced hearing loss (NIHL) have been found to be the factors most associated with tinnitus. The risk of NIHL amongst professional musicians is greater than that amongst the general population, meaning they may be at increased risk of tinnitus. METHODS: Seventy-four professional musicians completed an online survey involving closed and open-ended questions, and completed the Tinnitus fuctional Index (TFI) questionnaire. Descriptive statistics and thematic analysis of open-ended qualitative responses were used to analyse the data. RESULTS: Three themes were generated from the analysis of the responses to the open-ended questions. These themes were: (1) the impact of tinnitus on the lives of professional musicians, (2) professional musician experience of tinnitus services, support, and hearing health and safety, and (3) the support professional musicians want. The mean global TFI score for professional musicians was 39.05, interpreted as tinnitus being a moderate problem. Comparisons with general population data revealed lower TFI scores for the TFI subscales of ‘sense of control’ and ‘intrusiveness’ for professional musicians and higher for auditory difficulties associated with tinnitus amongst professional musicians. CONCLUSION: Tinnitus can negatively impact on professional musicians’ lives. There is a need for bespoke self-help groups, awareness raising, and education to prevent tinnitus and promote hearing health among musicians.

The Ideal

Hypospadias is associated with an increased incidence of "significant" urologic anomalies as compared with the general population. Most do not require immediate surgical intervention, but this information may be important in planning the long-term management of the boy, including follow-up and advice given in regard to contact sports. Ultrasonography avoids the possible hazards of intravenous urography and would seem to be the ideal screening test for detecting the urologic anomalies associated with hypospadias. Intravenous urography should be reserved for a selected group of children with hypospadias with abnormal ultrasonograms or urologic symptomatology.

Limited Role

Review of 825 musicians presenting with upper limb symptoms to a specialized musicians clinic in London shows that only 45% had a recognized structural disorder, of whom only 4% were possible candidates for surgery. Surgical experience on musicians is therefore limited and fragmented, and many misconceptions exist. The most common reason for surgery in this group is coincidental trauma (25%), followed by other common inflammatory and degenerative conditions seen in the general population. The indications for surgery and the techniques used need to be modified. Review of 49 consecutive professional musicians treated surgically along the guidelines discussed show that 98% returned to full-time professional playing, confirming the essential if limited role surgery plays in the care of musicians’ hands.

Caesalpinia Echinata

Abstract Caesalpinia echinata Lam. (pau-brasil) is a Brazilian tree with symbolic character for Brazilian forestry, which is at risk of extinction because of illegal logging activities and exportation as raw material for bows of string instruments. Additional studies are required to select substitutes for pau-brasil, i.e., other wood species are being sought with potentially suitable characteristics for bow manufacture. The present paper is dedicated to the evaluation of six native Brazilian woods by comparing their anatomical features, specific gravity, speed of sound propagation, and dynamic modulus of elasticity in relation to the corresponding properties of C. echinata that are considered as standard for bow manufacture. The results showed that length, diameter, lumen diameter, and wall thickness of fibers are the most important variables contributing to specific gravity. Additionally, ray dimensions influenced sonic velocity. The values of dynamic modulus of elasticity are directly related to dimensions of rays and fibers. Among the six woods included in this study, Dipteryx spp., Handroanthus spp., and Hymenaea spp. were considered as the best alternatives to C. echinata wood as sources of bow construction. The bows from the first two woods were already tested by professional musicians and their suitability was certified. The Diplotropis spp. wood also showed promising characteristics. Mezilaurus itauba and Astronium lecointei do not have the necessary properties for bows.

Abstract Abdominal wall hernias are a common problem in the general population. A Western estimate reveals that the lifetime risk of developing a hernia is about 2%.1–3 As a result, hernia repairs likely comprise the most frequent general surgery operations. More than 20 million hernias are estimated to be repaired every year around the world.4 Numerous repair techniques have been described to date however tension-free mesh repairs are widely used today because of their low hernia recurrence rates. Nevertheless, there are some ongoing debates regarding the ideal approach (open or laparoscopic),5,6 the ideal anesthesia (general, local, or regional),7,8 and the ideal mesh (standard polypropylene or newer meshes).9,10

The technique of labeling of macromolecules with ferritin conjugated antibody has been successfully used for extracellular antigen by means of staining the specimen with conjugate prior to fixation and embedding. However, the ideal method to determine the location of intracellular antigen would be to do the antigen-antibody reaction in thin sections. This technique contains inherent problems such as the destruction of antigenic determinants during fixation or embedding and the non-specific attachment of conjugate to the embedding media. Certain embedding media such as polyampholytes (2) or cross-linked bovine serum albumin (3) have been introduced to overcome some of these problems.

The reconstruction of a three-dimensional image of a specimen from a set of electron micrographs reduces, under certain assumptions about the imaging process in the microscope, to the mathematical problem of reconstructing a density distribution from a set of its plane projections.In the absence of noise we can formulate a purely geometrical criterion, which, for a general object, fixes the resolution attainable from a given finite number of views in terms of the size of the object. For simplicity we take the ideal case of projections collected by a series of m equally spaced tilts about a single axis.
