The Silent Epidemic of Road Traffic Injury: What Can Music Therapists do About It?
Simon Gilbertson
Voices: A World Forum for Music Therapy , 2008,
Abstract: Can music therapists do anything about road traffic injury and its effects? Road traffic crashes are responsible for up to 1.2 million deaths and up to 50 million injuries globally each year. One quarter of these injuries are traumatic brain injuries. In this paper, the literature related to music therapy and traumatic brain injury is reviewed. By analysing this literature, it becomes apparent that music therapists have provided for those injured almost to the exclusion of those affected by traumatic brain injury, the family, the community and the society. Using literature related to trauma, the author discusses ways in which music therapists may change the scope of music therapy in relation to caring for people affected by road traffic injury and considers the role music therapists may play in the prevention of road traffic injury in the future.

BMC Medical Research Methodology , 2006, DOI: 10.1186/1471-2288-6-56
Abstract: The checklist was developed by listing the most commonly used assessment criteria for clinical studies. Additionally, specific lists for individual applications were included. The categories of biases of internal validity (selection, performance, attrition and detection bias) correspond to structural, treatment-related and observational differences between the test and control groups. Analogously, we have extended these categories to address external validity and model validity, regarding similarity between the study population/conditions and the general population/conditions related to structure, treatment and observation.A checklist is presented, in which the evaluation criteria concerning external validity and model validity are systemised and transformed into a questionnaire format.The checklist presented in this article can be applied to both planning and evaluating of clinical studies. We encourage the prospective user to modify the checklists according to the respective application and research question. The higher expenditure needed for the evaluation of clinical studies in systematic reviews is justified, particularly in the light of the influential nature of their conclusions on therapeutic decisions and the creation of clinical guidelines.It is known that clinical studies can generate discordant results. This observation is addressed scientifically in various ways. Deviant study results may be understood as an expression of spreading or scattering from a supposed true value (whereas deviation depends on the precision of the methods). An alternative approach is to explain differences not statistically but by way of content [1]. In considering individual studies, there should be an estimate to what extent the study conclusions are distorted by systematic factors of bias. Here the focus lies usually on so called internal validity, the comparability of test and control groups. (Detailed definitions of internal validity and other validity categories are given
Myelodysplastic Syndrome with t(1;7) Associated with Marked Dysmegakarypoiesis & Severe Thrombocytopenia: A Case Report and Review of the Literature
Michael Gilbertson,Annabel Tuckfield,Surender Juneja
Case Reports in Hematology , 2012, DOI: 10.1155/2012/167653
Abstract: We present the case of a 70-year-old woman who had a bone marrow examination performed to investigate marked thrombocytopenia in the context of a recent history of metastatic glucagonoma. Surprisingly this identified marked dysmegakaryopoiesis and fulfilled diagnostic criteria for refractory cytopenia with multilineage dysplasia, with a relatively uncommon associated cytogenetic lesion t(1;7). We present the case and review the literature of this cytogenetic lesion.
An Unusual Complication of an Infiltrated Intravenous Catheter: Heterotopic Ossification in a Newborn
Lavi Nissim,Dorothy Gilbertson-Dahdal
Journal of Radiology Case Reports , 2008, DOI: 10.3941/jrcr.v2i2.30
Abstract: Heterotopic ossification refers to formation of lamellar bone in soft tissues. The etiology is diverse and includes genetic, post-traumatic, and metabolic causes. Elicitation of bone morphogenic proteins are thought to play a key role in the pathogenic process. Initially, heterotopic ossification presents a clinical and radiographic challenge in that it can be mistaken for other more worrisome entities which present with calcified soft tissue masses. However, a spontaneous clinical resolution, temporal relationship to an inciting agent, and radiographic evolution to a peripherally-calcified lesion are all clues to the diagnosis. Here we present the clinical and radiographic features of heterotopic ossification as a result of an infiltrated peripheral IV.

Abstract: We present the case of a 70-year-old woman who had a bone marrow examination performed to investigate marked thrombocytopenia in the context of a recent history of metastatic glucagonoma. Surprisingly this identified marked dysmegakaryopoiesis and fulfilled diagnostic criteria for refractory cytopenia with multilineage dysplasia, with a relatively uncommon associated cytogenetic lesion t(1;7). We present the case and review the literature of this cytogenetic lesion. 1. Case Presentation A 70-year-old woman was referred to our institution in June 2010 for further evaluation of moderate to severe pancytopenia. She was clinically relatively well with no recent infective symptoms or bleeding events. Her past history was noteworthy for metastatic glucagonoma diagnosed in June 2009, for which she had undergone surgical resection and radiolabelled octreotide therapy. She had an FDG-PET scan which confirmed metabolic remission in March 2010 and was scheduled to continue octreotide therapy at the time of referral however, the degree of thrombocytopenia limited the patient’s tolerability of further octreotide. She also had insulin requiring type 2 diabetes as a result of the glucagonoma. Her initial full blood parameters (FBE) were Hb 107?g/L, MCV 105 fL, WBC 2.1 × 109/L (Neutrophils 1.6 × 109/L, Lymphocytes 0.3 × 109/L), and Platelets 20 × 109/L. The blood film showed mild red cell anisocytosis with macrocytosis and moderate numbers of tear-drop red cells (Figure 1). Granulocytes showed mild left shift and dysplastic changes (hyposegmented and hypersegmented neutrophils). Platelets were markedly reduced and showed marked anisocytosis with many large forms as well as abnormal granulation. Renal and liver functions were within normal limits. Previous FBEs performed at our institution in September 2008 revealed completely normal full blood parameters. Clinical examination was non-contributory. Figure 1: Mild red cell anisocytosis with macrocytosis and moderate numbers of tear drops. Mild granulocyte left shift and dysplastic changes (hyposegmented and hypersegmented neutrophils). Peripheral blood film. Wrights stain ×200. Bone marrow examination was undertaken to exclude metastatic disease—of which there was none demonstrated on three heamatoxylin and eosin (H&E) levels and relevant neuroendocrine immunohistochemistry (cytokeratin and synaptophysin Figures 5 and 6, resp.). Surprisingly, the bone marrow showed mild increase in megakaryocyte numbers with marked megakaryocyte dysplasia; although they appeared normal in size, the nucleus of most megakaryocytes was

Although most patients eventually reach this target, the time required varies substantially. This study aimed to determine whether length of time with below-target hemoglobin levels after dialysis initiation is associated with medical costs, and if so, whether intermediate factors underlie the associations. US patients initiating dialysis in 2002 were studied using the Centers for Medicare and Medicaid Services ESRD database. Anemia persistence (time in months with hemoglobin below 110 g/L) was determined in a six-month entry period, and outcomes were assessed in the subsequent six-month follow-up period. The structural equation modeling technique was used to evaluate associations between persistent anemia and medical costs and to determine intermediate factors for these associations. The study included 28,985 patients. Mean per-patient-per-month medical cost was $6267 (standard deviation $5713) in the six-month follow-up period. Each additional month with hemoglobin below 110 g/L was associated with an 8.9% increment in medical cost. The increased cost was associated with increased erythropoietin use and blood transfusions, and increased rates of hospitalization and vascular access procedures in the follow-up period.

BMC Nephrology , 2013, DOI: 10.1186/1471-2369-14-44
Abstract: Background Some hemodialysis patients require large doses of erythropoiesis-stimulating agents (ESAs) to manage anemia. These patients, termed “ESA hyporesponsive,” have been characterized using various definitions. We applied three definitions of hyporesponsiveness to a large, national cohort of hemodialysis patients to assess the impact of definition on counts and on characteristics associated with hyporesponsiveness. Methods We studied point-prevalent hemodialysis patients on May 1, 2008, with Medicare as primary payer, who survived through December 31, 2008. Included patients received recombinant human erythropoietin (EPO) in each month, August-December. Hyporesponsiveness definitions were: above the ninetieth percentile of total monthly EPO dose; above the ninetieth percentile of total monthly EPO dose divided by weight in kg; above the ninetieth percentile of total monthly EPO dose divided by hemoglobin level. Hyporesponsiveness was further classified as chronic, acute, or other. Comorbid conditions were assessed before and concurrent with the hyporesponsive period. Results Women, African Americans, and patients aged <40 years, with cause of renal failure other than diabetes or hypertension, or longer dialysis duration, were more likely to be hyporesponsive. Antecedent comorbid conditions most predictive of any subsequent hyporesponsiveness were congestive heart failure, peripheral vascular disease, other cardiac disease, gastrointestinal bleeding, and cancer. Concurrent comorbid conditions most strongly associated with any hyporesponsiveness were gastrointestinal bleeding and cancer. All conditions were somewhat more likely when ascertained concurrently. Comorbidity burdens were lowest for non-hyporesponsive patients. Conclusions As associations were similar between patient characteristics and three methods of characterizing EPO hyporesponsiveness, the simplest definition using EPO dose can be used.
