The aim of the study is to assess the diagnostic value of preoperative conventional radiographs for diagnosing infection associated with internal fixation devices. We prospectively collected data of patients undergoing removal of internal fixation devices for any reason. Infection was diagnosed in case of purulence, sinus tract, positive histopathology and/or positive peri-implant tissue or sonication fluid culture. In radiographs radiolucent lines, implant breakage or displacement, or periosteal reaction were assessed. White blood cell count (WBC) and serum C-reactive protein (CRP) were determined at admission. We included 421 surgeries in 380 patients (median age 53.6 years, range 11-98 years), mainly indicated for infection (24.9%), nonunion (20.0%) and symptomatic implants (13.5%). Radiologic signs of infection included radiolucent lines (11.4%); implant breakage (12.4%) or displacement (10.7%); and periosteal reaction (7.1%). Infection was confirmed in 116 cases (27.6%). Only radiolucent lines (OR = 1.86 [95%CI 1.00-3.38]) and periosteal reaction (OR = 2.48 [95%CI 1.17-5.26]) were associated with infection, with a low sensitivity (16.4 and 12.1%, respectively), and high specificity (90.5 and 94.8%, respectively). Preoperative WBC and CRP had a sensitivity of23.0 and 35.3%, and specificity of91.7 and 89.5%, respectively. Radiological signs suggestive of infection were uncommon. Radiolucency and periosteal reaction were associated with infection, though with low sensitivity.Radiological signs suggestive of infection were uncommon.

There has been a growing interest in using all pedicle screw construct in posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) surgery in recent years. However, studies focusing on perioperative outcome and complications utilizing only pedicle screw system in AIS population are lacking. This study aims to evaluate perioperative outcomes and to determine the prevalence of major and minor complications following single-staged PSF for AIS. In this retrospective study of prospectively collected data, 1057 AIS patients operated between 2012 and 2019 were included. Main outcome measures were operative time, intraoperative blood loss, allogeneic blood transfusion rate, length of hospital stay after surgery, complication rate, and mean drop of haemoglobin (Hb) level. We documented the number of fusion levels, screw density, and postoperative radiographic parameters. There were 917 females and 140 males. Majority were Lenke 1 curve type (46.9%). Mean age was 15.6 ± 3.7 years, with mean BMI of te of minor complications. Rate of neurologic complication was 0.47% while non-neurologic postoperative complications was 1.80% with infection being the leading complication at 1.32%. Chronic low back pain is the most frequent medical problem and the condition with the most years lived with disability in Western countries. The objective of this study was to assess a new treatment, Medi-Taping, which aims at reducing complaints by treating pelvic obliquity with a combination of manual treatment of trigger points and kinesio taping in a pragmatic RCT with pilot character. One hundred ten patients were randomized at two study centers either to Medi-Taping or to a standard treatment consisting of patient education and physiotherapy as control. Treatment duration was 3weeks. Measures were taken at baseline, end of treatment and at follow-up after 2months. Main outcome criteria were low back pain measured with VAS, the Chronic Pain Grade Scale (CPGS) and the Oswestry Low Back Pain Disability Questionnaire (ODQ). Patients of both groups benefited from the treatment by medium to large effect sizes. All effects were pointing towards the intended direction. While Medi-Taping showed slightly beutsches Register Klinischer Studien). URL of trial registry record https//www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00017051 . The COVID-19 pandemic has required governments around the world to suspend face-to-face learning for school and university students. Colleges of pharmacy are faced with the challenge of training students in hospitals that are under considerable pressure at this time. The government of Saudi Arabia has moved all classes and training online to limit the spread of the virus. This study describes the experience of the Introductory and Advanced Pharmacy Practice Experience (IPPE and APPE) students and preceptors engaged in the virtual IPPE training. A cross-sectional study was conducted to describe and appraise the implemented virtual IPPE training from the experiences of IPPE and APPE students, and their preceptor. click here The IPPE students described their experiences in close-ended questionnaires, while APPE students in open-ended questionnaires, and the preceptor described the experiences in narrative. The study focused on highlighting the advantages, opportunities, challenges, and shortcomings of the virtual traino improve IPPE students' learning experiences and outcomes.Future training programs should be organized to overcome the challenges and to maximize the benefits of training experiences. Schools of pharmacy may benefit from the training materials constructed, prepared, and administered by APPE students to improve IPPE students' learning experiences and outcomes. Controlled vocabularies are fundamental resources for information extraction from clinical texts using natural language processing (NLP). Standard language resources available in the healthcare domain such as the UMLS metathesaurus or SNOMEDCT are widely used for this purpose, but with limitations such as lexical ambiguity of clinical terms. However, most of them are unambiguous within text limited to a given clinical specialty. This is one rationale besides others to classify clinical text by the clinical specialty to which they belong. This paper addresses this limitation by proposing and applying a method that automatically extracts Spanish medical terms classified and weighted per sub-domain, using Spanish MEDLINE titles and abstracts as input. The hypothesis is biomedical NLP tasks benefit from collections of domain terms that are specific to clinical subdomains. We use PubMed queries that generate sub-domain specific corpora from Spanish titles and abstracts, from which token n-grams are collected and metrics of relevance, discriminatory power, and broadness per sub-domain are computed.
