Coexistence of primary central nervous system lymphoma and primary breast lymphoma: Clinical presentation,imaging features,and treatment management

The presence of synchronous dual hematological diseases is an uncommon finding. We report an unusual case of coexistence of primary central nervous system lymphoma and primary breast lymphoma without systemic involvement in an immunocompetent patient. To our knowledge a similar case has not yet been reported in the literature. We especially focus on presenting the imaging features, the associated clinical findings and treatment management of each entity, with the aim of raising awareness on these two rare types of lymphomas and the possibility of their coexistence.     

Prevalence of drug interactions in hospital healthcare

Aim of the review To study the prevalence of drug interactions in hospital healthcare by reviewing literature. Method A review was carried out of studies written in Spanish and English on the prevalence of drug interactions in hospital care published in Pubmed between January 1990 and September 2008. The search strategy combined free text and MeSH terms, using the following keywords: ??Drug interaction??, ??prevalence?? and ??hospital??. For each article, we classified independent variables (pathology, age of population, whether patients were hospitalized or not, geographical location, etc.) and dependent variables (number of interactions per 100 patients studied, prevalence of patients with interactions, most common drug interactions, and others). Results The search generated 436 articles. Finally, 47 articles were selected for the study, 3 provided results about drug interactions with real clinical consequences, 42 about potential interactions, and 2 described both. The prevalence of patients with interactions was between 15 and 45?% and the number of interactions per 100 patients was between 37 and 106, depending on the group of studies analyzed. There was a considerable increase in these rates in patients with heart diseases and elderly persons. Conclusion There is a large number of studies on the prevalence of drug interactions in hospitals but they report widely varying results. The prevalence is higher in patients with heart diseases and elderly people.     

High risk for sleep apnea in the Berlin questionnaire and coronary artery disease

Introduction  

Obstructive sleep apnea (OSA) affects up to 30% of the adult population and is a risk factor for coronary artery disease (CAD). The diagnostic process, involving polysomnography, may be complex. Berlin questionnaire (BQ) is a validated and economical screening tool.     

Iniciativa GOLD 2011. ¿Cambio de paradigma?

Ten years after the publication of the first GOLD strategy (Global Strategy for the Diagnosis, Management, and Prevention of COPD) for chronic obstructive pulmonary disease (COPD), the new revision published on the GOLD website at the end of 2011 represents a significant change in the diagnostic approach, clinical evaluation and therapeutic treatment of the disease. This revision debates not only the most significant aspects, which remain relatively intact, but also, and in particular, those that have been substantially modified compared with the GOLD revision from 2006.     

Effects of radial shock waves therapy on osteoblasts activities

Radial shock waves therapy (RSWT) differs from extracorporeal shock waves therapy (ESWT) in that it produces a non-focused wave that is dissipated radially at the skin. Few studies have yet explored the effects of RSWT on bone tissue. Osteoblasts in culture flasks were studied by polymerase chain reaction after treatment with RSW (500 impulses, 0.05?mJ/mm²). An inhibited osteoblastogenesis was observed, with a statistically significant reduction in type 1 collagen, osterix, bone sialoprotein and receptor activator NF kappa ligand expression at 24 and 48?h, of osteocalcin at 24, 48 and 72?h, and osteopontin at 48 and 72?h. These findings show that RSWT is not indicated for treatment of delayed fracture union, pseudoarthrosis, and complex regional pain syndrome. The observed reduction in the receptor activator of nuclear factor-kB ligand/osteoprotegerin ratio suggests that it has an inhibiting effect on osteoclastogenesis, which could make it a useful tool for applications in proliferative diseases.     

Epidemiology of hip fractures in northwestern Italy: a multicentric regional study on incidence of hip fractures and their outcome at 3-year follow-up

Piedmont is a region in northwestern Italy counting 4.2 million inhabitants. The purpose of our study was to update data on incidence and outcomes of hip fractures (HF) in our region to present days. The data of all patients affected by HF in 2003 in Piedmont (total: 5,386 patients) were analyzed, determining the incidence of HF, mean age, sex, fracture pattern and treatment adopted. Additionally, 564 patients underwent a questionnaire on comorbidities, complications, functional outcome and survivorship. Overall incidence of HF was 126.13/100,000 inhabitants-year. Mean hospitalization was 13.67 days. Mean time to surgery was 2.67 days. Survivorship was 94% at 3-month, 71.32% at 1-year and 60.21% at 3-year follow-up. These up-to-date data on HF in our region are in accordance with the international literature and could prove useful for Orthopaedic and Trauma surgeons for giving information to patients and their relatives.     

Validity and reliability of the SPORTS score

Purpose  

Successful outcomes for an athlete usually consist of returning to their sport. The Subjective Patient Outcome for Return to Sports (SPORTS) score has been recently proposed as an easy to use score for evaluating an athlete’s ability to return to their sport. The aim of this study was to test the reliability and validity of the SPORTS score in athletes 5–10 years after anterior cruciate ligament reconstruction.
