Study Design: Cross-sectional study.Objective: To investigate the equivalence of electronic and paper version of self-report questionnaires for the assessment of disability, pain, fear of movement, depression, and physical activity of patients with chronic low back pain (LBP).Summary Of Background Data: Paper and electronic versions of self-report questionnaires are commonly used for assessment of patients with LBP. However, the equivalence of self-report questionnaires commonly used for assessment of patients with chronic LBP remains unclear.Methods: Seventy-nine individuals with chronic LBP seeking physiotherapy care were recruited. Participants attended the clinic twice with an interval of 1 week and completed the self-reported questionnaires in a random order. The following questionnaires were administered: Roland Morris Disability Questionnaire (RMDQ); 11-point numerical rating scale (NRS); Tampa Scale for Kinesiophobia (TSK); Center for Epidemiological Studies-Depression (CES-D), and Baecke Habitual Physical Activity Questionnaire (BPAQ). To investigate the equivalence between the two questionnaire versions, intraclass correlation coefficient with 95% confidence interval and Bland-Altman plotting was used.Results: The paper and electronic versions of the RMDQ, TSK, and CES-D showed good reliability and the showed moderate reliability. In contrast, the NRS showed poor reliability between the electronic and paper versions.Conclusion: Our findings support that the electronic version of the RMDQ, TSK, CES-D, and BPAQ can be administered in clinical and research settings for assessment of patients with chronic LBP. Nevertheless, electronic version of the NRS for assessment of pain intensity should not be used interchangeably in clinical practice in patients with chronic LBP.Level Of Evidence: 3.

Background: Exogenous materials may be encountered in skin biopsies as contamination. Contamination may occur during the biopsy procedure in the clinic or during tissue processing in the laboratory. Although the experienced pathologist may often instinctively ignore clear examples of contamination, such tissue may be a source of confusion for young pathologists and those in training. Foreign materials can typically be recognized as exogenous by morphology, polarizability, and the presence or absence of a tissue reaction, but we have rarely encountered situations in which exogenous materials could be misinterpreted as organisms, either by their morphologic appearance or staining properties., Methods: Exogenous materials used during skin biopsy and grossing were embedded in a nonhuman tissue scaffold and prepared into histologic slides. Hematoxylin and eosin (H&E), periodic acid-Schiff with diastase, and Grocott methenamine silver stains were performed, and each material was evaluated under polarized microscopy., Results: Exogenous materials were divided into the following 3 categories with shared morphologic appearances and staining properties: suture materials, plant-based materials, and synthetic materials., Conclusion: We present a comprehensive characterization of the morphologic and cytochemical staining properties of multiple exogenous materials that may contaminate a skin biopsy. This characterization will aid the pathologist by providing a mechanism to identify potential contaminants in skin biopsies., Competing Interests: Dr. Gardner has disclosed that he was a consultant for Bristol-Myers Squibb and Leica Biosystems.

Objective: We hypothesized that a paper documentation and discharge bundle can expedite patient care during an influenza-related surge., Methods: Retrospective cohort study of low-acuity patients younger than 21 years surging into a pediatric emergency department between January and March 2018 with influenza-like illness. Patient visits documented using a paper bundle were compared with those documented in the electronic medical record on the same date of visit. The primary outcome of interest was time from physician evaluation to discharge for patient visits documented using the paper bundle compared with those documented in the electronic medical record. Secondary outcome was difference in return visits within 72 hours. We identified patient and visit level factors associated with emergency department length of stay., Results: A total of 1591 patient visits were included, 1187 documented in the electronic health record and 404 documented using the paper bundle. Patient visits documented using the paper bundle had a 21% shortened median time from physician evaluation to discharge (41 minutes; interquartile range, 27-62.8 minutes) as compared with patient visits documented in the electronic health record (52 minutes; interquartile range, 35-61 minutes; P < 0.001). There was no difference in return visits (odds ratio, 0.7; 95% confidence interval, 0.2, 2.2)., Conclusions: Implementation of paper charting during an influenza-related surge was associated with shorter physician to discharge times when compared with patient visits documented in the electronic health record. A paper bundle may improve patient throughput and decrease emergency department overcrowding during influenza or coronavirus disease-related surge., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

The authors aim to analyze the effects of oral antibiotic treatment for traumatic tympanic membrane perforations and to compare the outcomes of patients with traumatic tympanic membrane perforation after paper-patching procedure and spontaneous healing.In this study, 80 patients with traumatic tympanic membrane perforation diagnosed in the otorhinolaryngology emergency department and outpatient clinic from March 2010 to January 2015 were retrospectively reviewed. If the patient is diagnosed at first week and the edge of perforation is moist with blood, our routine procedure is paper-patching (group 1). However, if the patients reject treatment or delay in admission, the authors follow up patients for spontaneous closure (group 2). Some of the patients got oral antibiotics for 7 days (amoxicillin/clavulanic acid, 1000 mg 2 times/d) while some others did not. Closure rates and effectivity of oral antibiotics were evaluated and compared between 2 groups.In total, 80 patients were analyzed. The closure rates of perforations were 95.2% for group 1 (n = 42) and 81.6% for group 2 (n = 38). Although the paper-patched patients (group 1) perforation closure rate (95.2%) is higher than the nontreated patients (group 2) closure rate (81.6%), it is not statistically significant (P > 0.05). Antibiotic administered 55 patients had a significantly higher closure rate (94.5%) than the 25 patients who are not treated with antibiotics (76%) (P = 0.023; P < 0.05).In patients with traumatic tympanic membrane perforations, spontaneous closure rate is quite high. This study showed us that antibiotherapy and paper-patch treatments increase the healing rates.

Objective: The aim of this study was to investigate the association between occupational exposure and chronic rhinosinusitis., Methods: A random population from the region of Telemark, aged 16 to 50 years, answered a respiratory questionnaire including questions on chronic rhinosinusitis and exposure in the occupational environment., Results: A total of 16,099/48,142 subjects responded. The prevalence of chronic rhinosinusitis was 9%. Exposure associated with chronic rhinosinusitis comprised paper dust [odds ratio (OR) 1.3, 95% confidence interval (95% CI) 1.1 to 1.5], cleaning agents (OR 1.2, 95% CI 1.0 to 1.3), metal dust (OR 1.3, 95% CI 1.1 to 1.6), animals (OR 1.2, 95% CI 1.0 to 1.5), moisture/mould/mildew (OR 1.3, 95% CI 1.1 to 1.5), and physically strenuous work (OR 1.4, 95% CI 1.2 to 1.7)., Conclusion: Occupational exposure to paper dust, cleaning agents, metal dust, animals, moisture/mould/mildew, and physically strenuous work was independently related to having chronic rhinosinusitis. An occupational history should be reviewed when assessing patients with chronic rhinosinusitis.

This article reports our experience in developing a computerized cognitive assessment method in a nurse-led clinic. The assessment and report-writing time and the accuracy of using a computer as an assessment medium were compared with assessments that use the traditional pencil-and-paper method. The attitudes of professionals and service users toward the computerized approach were also collected. The results found that the computerized approach not only helped to reduce the time spent making assessments and writing reports but also improved the accuracy of the assessment when compared with the pencil-and-paper method. Most of the professionals and service users who were interviewed responded positively toward computerized assessments. The experience gained in this study will also help us to standardize our assessment procedures, promote communication among members of the clinical team, and facilitate data management and clinical research.

Thoron (Rn) exhalation from building materials has become increasingly recognized as a potential source for radiation exposure in dwellings. However, few studies have focused on mitigation strategies to reduce exposure from thoron and its progeny. Therefore, the purpose of this study is to (1) determine the reduction in thoron exhalation from building materials applied with regularly available surface barriers and (2) investigate the effects from surface roughness of the base material, barrier thickness, and surface cover on the thoron-retaining action of the surface barrier. The findings from this study demonstrate that regular surface barriers provide a potentially significant reduction in thoron exhalation, which can reach more than 90%. Despite this reduction, there are also materials that provide no reduction at all. Based on this work, no commonly available product property could be identified that provides good guidance on the barriers' performance to reduce thoron exhalation.

Although there were previous studies on the clinical aspects such as etiology, treatment modalities, studies regarding the necessity of radiologic evaluation for nasal foreign body were limited. The aim of this study is to evaluate the necessity and indication of radiologic evaluation for nasal foreign bodies. There are consecutive patients aged less than 10 years who presented with suspected foreign bodies in nasal cavity. We reviewed the patient's age and sex, including the methods of evaluation, management tools, and types of foreign bodies. There were 35 cases (11.4%) on whom radiographs were performed in the 24 uncooperative patients and 11 cooperative patients who were not identified with any foreign bodies via nasal endoscopy. Among them, only 4 cases had positive reports of foreign body and the others were normal radiologic findings. We suggest that the radiologic evaluation is always not necessary to find the location of nasal foreign bodies. It, however, should be performed in cases of negative findings of physical examination with anterior rhinoscopy or sinus endoscopy and unwitnessed foreign bodies to rule out metallic contents, especially button type battery.

Molecular testing of tumors from formalin-fixed paraffin-embedded (FFPE) tissue blocks is central to clinical practice; however, it requires histology support and increases test turnaround time. Prospective fresh frozen tissue collection requires special handling, additional storage space, and may not be feasible for small specimens. Filter paper-based collection of tumor DNA reduces the need for histology support, requires little storage space, and preserves high-quality nucleic acid. We investigated the performance of tumor smears on filter paper in solid tumor genotyping, as compared with paired FFPE samples. Whatman FTA Micro Card (FTA preps) smears were prepared from 21 fresh tumor samples. A corresponding cytology smear was used to assess tumor cellularity and necrosis. DNA was isolated from FTA preps and FFPE core samples using automated methods and quantified using SYBR green dsDNA detection. Samples were genotyped for 471 mutations on a mass spectrophotometry-based platform (Sequenom). DNA concentrations from FTA preps and FFPE correlated for untreated carcinomas but not for mesenchymal tumors (Spearman σ=0.39 and σ=-0.1, respectively). Average DNA concentrations were lower from FTA preps as compared with FFPE, but DNA quality was higher with less fragmentation. Seventy-six percent of FTA preps and 86% of FFPE samples generated adequate DNA for genotyping. FTA preps tended to perform poorly for collection of DNA from pretreated carcinomas and mesenchymal neoplasms. Of the 16 paired DNA samples that were genotyped, 15 (94%) gave entirely concordant results. Filter paper-based sample preservation is a feasible alternative to FFPE for use in automated, high-throughput genotyping of carcinomas.

Objective: To determine the accuracy of paper cardiopulmonary resuscitation records., Design: Case series., Setting: Twenty-six-bed video-monitored pediatric cardiac ICU., Patients: All patients who had a resuscitation event with available video and electronically stored vital sign and waveform data from May 2012 to February 2013., Interventions: None., Measurements and Main Results: There were 41 cardiopulmonary resuscitation events during the study period. Fifteen had complete and valid data from the paper cardiopulmonary resuscitation forms, the retrieved monitor data, and the continuous bedside video monitoring. These 15 events occurred in 12 individual patients, and there was 100% agreement of data in the documentation of interventions in place (ventilation, arterial catheter, pulse oximetry, and vascular access) and in the presence of a witness at the onset of the arrest. All events were witnessed. Of the 15 events, video and monitor review revealed that 14 used waveform and numeric capnometry to confirm endotracheal tube/tracheostomy placement, but this section was only completed on the paper cardiopulmonary resuscitation record in three of the 14 cases. All records showed no discrepancies in the time of return of spontaneous circulation. The video and monitor review revealed delay in initiating cardiopulmonary resuscitation (mode, 2 min; two cases ≥ 7 min) and shockable rhythms (ventricular arrhythmia) in two cases. A sign of pulseless state was discovered in seven cases classified on the paper record as "always with a pulse." Those include sudden loss of consciousness, flat arterial line tracing, and abrupt drop in the partial pressure of exhaled carbon dioxide tracing (< 10 mm Hg)., Conclusions: Eyewitness accounts of cardiopulmonary resuscitation are often inaccurate and incomplete. Review of information from video and electronically stored vital sign and waveform data provides more accurate information than review of paper-based cardiopulmonary resuscitation records and may provide the insight necessary to improving cardiopulmonary resuscitation.

The purpose of this study was to compare the outcomes of patients with acute tympanic membrane perforation after spontaneous healing and paper-patching procedure., Methods Design, Setting, and Participants: In this study, we performed a retrospective chart review with a prospective follow-up in 63 patients with tympanic membrane perforations. The patients undergoing a paper-patching procedure were assigned to group 1 (n = 33), whereas the patients that healed spontaneously were included in group 2 (n = 30). Retrospective analyses of the otoscopic examination findings and audiometric test results of the groups at the sixth-week follow-up were compared., Results: Eardrum healing was achieved in 90.9% of the patients in group 1 and 76.7% of the patients in group 2 at the sixth week (P > 0.05). The mean values of air conduction were significantly improved, and the air-bone gap was markedly decreased in the patients treated with paper patching, when compared with the patients in group 2 (P < 0.001). The area of perforation was found to be inversely related to the healing success., Conclusions: Early intervention by paper patching, which is a readily applicable procedure, may be offered to the patients with acute perforation of the tympanic membrane, because of the slightly better closure rates and significantly higher hearing functions when compared with simple observation.

Purpose: To introduce a novel interferometer and provide clinical data based on its use., Methods: Twenty-two normal subjects, 27 patients with dry eye syndrome, 1 patient with obstructive meibomian gland dysfunction, and 2 patients with ocular graft-versus-host disease were included in the study. We cut a piece of copy paper to create an interferometer comprising a handle, a window, and an illumination area. The patient sits in front of a biomicroscope with his or her head fixed on the headrest. The examiner holds the handle of the interferometer 10 mm from the front of the patient's eye. The examiner positions the illumination beam of the biomicroscope at the "illumination area." The examiner then observes a lipid layer interference pattern on the cornea through the window., Results: For the normal subjects, wave or amorphous patterns with white or grey color were observed in interferometry. The mean estimated lipid layer thickness in the dry eye group (43 ± 9 nm) was significantly thinner than that of the normal group (59 ± 29 nm) (P = 0.021). For the patient with obstructive meibomian gland dysfunction, interferometry revealed a white interference pattern (30 nm). For ocular graft-versus-host disease, the lipid pattern was brown and blue (165 nm). Patients felt no discomfort, and no complications occurred during examination., Conclusions: We could successfully obtain photographs of the lipid layer pattern with this novel interferometer without additional equipment or cost. This interferometer may be useful for research regarding the pathophysiology, diagnosis, and treatment of dry eye.
