Abstract
BACKGROUND Occupationally related limitations of earning capacity can be recognized under social legislation and may be subject to compensation ("reduction in earning capacity"). For this purpose, legislators have defined a list of occupational diseases ("BK list"). Recognition of an occupational disease requires a legal assessment procedure based on a medical appraisal. The aim of the assessment is to prove the "causality" and the "causality giving rise to liability". METHOD In addition to clinical findings and workplace analyses, imaging methods (projection radiography, MRI) are primarily used to substantiate liability. These methods enable proof of load-conforming damage patterns for occupational diseases 2108/2110 (damage to intervertebral discs). RESULTS AND CONCLUSION In addition to the legal background, the following review article primarily presents the image criteria for load-conforming damage patterns of the spine. On the basis of the consensus paper on the "Assessment of occupational disc diseases of the lumbar spine", image criteria are assigned to age-atypical grades of findings, and "typical constellations of findings" are defined for vibration (BK 2108) or lifting (BK 2110) loads. The aim of Part 1 is to explain the image criteria of the comparative images presented as image plates in Part 2 and thus to present a reference catalog of findings. KEY STATEMENTS · Occupational diseases are defined by legislators in the "List of Occupational Diseases".. · For occupational intervertebral disc diseases (BK 2108/2110), constellations of findings are defined.. · In the context of imaging diagnostics, a large number of image criteria are used.. · Part 1 explains the basics.. · Part 2 provides the image criteria on the basis of "comparative images" as a reference catalog..

Abstract
The prevalence of Work-Related Musculoskeletal Disorders (WRMSDs) among ultrasound professionals has been significant. National and international efforts to create industry standards have focused primarily on injuries in sonographers. In addition, the Centers for Disease Control and Prevention (CDC) and National Institute for Occupational Safety & Health (NIOSH) have published documents related to this occupational exposure. There has also been significant attention on equipment utilization and design to help reduce the prevalence of WRMSDs. The American Institute of Ultrasound in Medicine (AIUM) developed the AIUM Practice Principles for Work-Related Musculoskeletal Disorder in collaboration with other organizations whose members use ultrasound [see Collaborating Societies and Representatives]. This document supports the "Industry Standards for the Prevention of Work-Related Musculoskeletal Disorders in Sonography" and aims to expand on these Standards to include safety practices for all health care professionals who utilize ultrasound. These professionals include members of the scientific community, a wide variety of medical professionals, and dental professionals. These ultrasound users and operators will collectively be referred to in this document as "operator(s)" except in those instances where data addressed those holding a specific job title, such as sonographer. In addition, this document will support guidance for quality improvement specific to preventing and reducing injury rates.

Abstract
The utility of chest x-ray examination (CXR) in mandatory annual health examinations for occupational health is debatable in Japan. This study aimed to provide basic data to consider future policies for mandatory annual health examinations in the workplace. A nationwide descriptive survey was performed to determine the rate of detection of tuberculosis, lung cancer, and other diseases through CXR in organizations associated with National Federation of Industrial Health Association. The rate of finding on CXR conducted during annual health examinations in FY2016 was evaluated. Data regarding diagnosis based on follow-up examination findings were obtained and compared with the national statistics. In addition, CXR findings were compared with the results of low-dose lung computed tomography performed at the Hitachi Health Care Center. From 121 surveyed institutions, 88 institutions with 8,669,403 workers were included. For all ages, 1.0% of examinees required follow-up examination. Among 4,764,985 workers with diagnosis data, the tuberculosis detection rate was 1.8–5.3 per 100,000 persons. For Lung cancer, 3,688,396 workers were surveyed, and 334 positive cases were detected. The lung cancer detection rate using CXR was 9.1–24.4 per 100,000 persons. From 164 cases with information regarding the clinical stage, 72 (43.9%) had Stage I lung cancer. From 40,045 workers who underwent low-dose computed tomography multiple times, 31 lung cancer cases, all with Stage I disease, were detected (detection rate: 77.4 per 100,000 persons). Our findings suggest that CXR plays a little role in the detection of active tuberculosis. With regard to LC screening, the detection rate of LC by CXR was lower, approximately 50%, than the expected rate (41.0 per 100,000 persons) of LC morbidity based on the age–sex distribution of this study population. However, the role of CXR for LC screening cannot be mentioned based on this result, because assessment of mortality reduction is essential to evaluate the role.

Abstract
With the growing population and rapid change in the social environment, nurses in China are suffering from high rates of stress; however, the neural mechanism underlying this occupation related stress is largely unknown. In this study, mental status was determined for 81 nurses and 61 controls using the Symptom Checklist 90 (SCL-90) scale. A subgroup (n = 57) was further scanned by resting-state functional MRI with two sessions. Based on the SCL-90 scale, "somatic complaints" and "diet/sleeping" exhibited the most prominent difference between nurses and controls. This mental health change in nurses was further supported by the spatial independent component analysis on functional MRI data. First, dynamic functional connectome analysis identified two discrete connectivity configurations (States I and II). Controls had more time in the State I than II, while the nurses had more time in the State II than I. Second, nurses showed a similar static network topology as controls, but altered dynamic properties. Third, the symptom-imaging correlation analysis suggested the functional alterations in nurses as potential imaging biomarkers indicating a high risk for "diet/sleeping" problems. In summary, this study emphasized the high risk of mental deficits in nurses and explored the underlying neural mechanism using dynamic brain connectome, which provided valuable information for future psychological intervention.

Abstract
PURPOSE Photic retinal toxicity induced by exposure to arc welding can lead to irreversible vision loss. Serial multimodal imaging is characterized in a patient with outer retinal damage secondary to welder's maculopathy. METHODS A single case was retrospectively reviewed. RESULTS Spectral domain optical coherence tomography acutely revealed disruption of the ellipsoid zone, hyperreflective bands through the outer nuclear layer, and outer retinal cavitation consistent with phototoxicity. Subsequently, disruption and hypertrophy of the subfoveal retinal pigment epithelium developed. Autofluorescence depicted central hypoautofluorescence. CONCLUSION We report serial multimodal imaging in welder's maculopathy to better characterize the evolution of lesions. Multimodal imaging including spectral domain optical coherence tomography in arc welding phototoxicity may share features with other forms of phototoxicity such as hand-held laser maculopathy.

Abstract
INTRODUCTION Musculoskeletal disorders (MSDs) currently represent the first occupational health problem. Tendinopathy of the shoulder is the most common occupational diseas. It is responsible for variable aftereffects arriving until the articular steepness. AIM To determine the influence of clinical and radiological investigations in setting the rate of permanent partial disability related to occupational shoulder tendinopathies. METHODS This is a retrospective study of 63 patients followed for tendinopathy of the shoulder. The files were collected from the regional commission of attribution of the rates of permanent partial incapacity of the victims of the occupational accidents and diseases. For each patient we collected the social and occupational data, the result of the clinical examination and the radiological investigations as well as the attributed PPD rate (partial permanent disability). The data analysis allowed to determine the variation of the PPD according to the articular mobility and according to the severity of the hurts revealed by the radiological investigations. RESULTS The average age of our patients was of 45 years with a feminine predominance (sex ratio 6.87). The patients were mainly workers of confections (51%). The imaging objectified a tendinopathy without tear in 23 cases (36,5 We showed that the rate of PPD increased in a proportional way according to the severity of the limitation of the mobility expressed in degrees lost of abduction or of extension as well as according to the gravity of the hurts revealed by the radiological investigations. CONCLUSION we were able to attribute for every type of radiological lesion and according to the limitation of the mobility an interval of rather specific PPD, this allows directing the experts in the compensation of occupational shoulder tendinopathy victims.

Abstract
Real-time risk assessment for work-related musculoskeletal disorders (MSD) has been a challenging research problem. Previous methods such as using depth cameras suffered from limited visual range and wearable sensors could cause intrusiveness to the workers, both of which are less feasible for long-run on-site applications. This document examines a novel end-to-end implementation of a deep learning-based algorithm for rapid upper limb assessment (RULA). The algorithm takes normal RGB images as input and outputs the RULA action level, which is a further division of RULA grand score. Lifting postures collected in laboratory and posture data from Human 3.6 (a public human pose dataset) were used for training and evaluating the algorithm. Overall, the algorithm achieved 93% accuracy and 29 frames per second efficiency for detecting the RULA action level. The results also indicate that using data augmentation (a strategy to diversify the training data) can significantly improve the robustness of the model. The proposed method demonstrates its high potential for real-time on-site risk assessment for the prevention of work-related MSD. A demo video can be found at https://github.com/LLDavid/RULA_2DImage.

Abstract
A large number of healthcare workers have been infected with coronavirus disease-2019 (COVID-19). We aimed to investigate their clinical and chest computed tomography (CT) characteristics.The clinical, laboratory test and CT features of 43 medical and hospital staff with confirmed COVID-19 (MP group, 26-70 years old) were retrospectively analyzed, and compared to 43 non-medical related patients (non-MP group, 26-71 years old). Follow-up CT characteristics were analyzed to assess the disease progression in the period of hospitalization.At admission, the main complaints of the MP group, including fever (81.4%), fatigue (48.8%) and cough (41.9%), were similar to the non-MP group. The C-reactive protein, erythrocyte sedimentation rate, and lactate dehydrogenase levels were higher in the non-MP group than the MP group (17.5 ± 22.4 mg/L, 20.2 ± 23.4 mm/H and 219 ± 66U/L, respectively, P < .05). Ground-grass opacities, consolidation, interstitial thickening were common CT features of both groups. The severity of opacities on initial CT were less in the MP group (5.3 ± 3.9 scores) than in the non-MP group (9.1 ± 4.8 scores, P < .05). Before regular treatments, the sum score of the opacities showed weak to moderate correlations with duration, C-reactive protein, erythrocyte sedimentation rate and lactate dehydrogenase levels (R ranged from 0.341-0.651, P < .05). In the study time window, the duration from illness onset to when the most obvious pulmonary opacities were observed, according to CT findings, were similar in the MP group (13.3 ± 6.6 days) and the non-MP group (13.8 ± 5.1 days, P = .69). Mild to moderate anxiety and depression were observed in both groups.Despite greater knowledge of how to protect themselves than the general population, healthcare workers are also susceptible to COVID-19 infection. Occupational exposure is a very important factor. Healthcare workers have a higher vigilance about the infection in the early stage of the disease.

Abstract
BACKGROUND Health care workers spend extended times standing and walking short distances and are at risk for development of chronic venous insufficiency (CVI). We conducted a hospital-wide venous screening program designed to measure the prevalence of and risk factors for clinical manifestations of CVI and ultrasound evidence of venous reflux or obstruction in health care workers. We also determined their risk for deep venous thrombosis (DVT). METHODS Free venous screening and education were offered to all hospital employees; the program started in April 2016, and results are presented from the first year. Demographics, medical history, and use of compression stockings were recorded. A physical examination determined the clinical class of the Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) classification for clinical disease, and an ultrasound test evaluated for reflux or obstruction in the common femoral vein, popliteal vein, and saphenofemoral junction. The Caprini score was recorded to evaluate risk of DVT. Descriptive statistics were reported, and logistic regression was used for multivariate analysis of risk factors. RESULTS We enrolled 636 participants (1272 legs); 93.0% were women. The median age was 42 years (interquartile range, 31-52 years), mean body mass index was 29.2 ± 6.6 kg/m2, and most participants were white (49.1%) or African American (39.5%); 18% reported having hypertension, 7.1% had diabetes, and 6.1% were current smokers. The majority reported occasional leg pain (72.7%) and evening leg swelling (42.3%). Only 2.7% used daily compression stockings. Clinical evidence of CVI was present in at least one leg in 69.1% (C1, 49.0%; C2, 17.7%; C3, 1.9%; C4, 0.2%; C5, 0.2%). Venous reflux was present in at least one leg in 82.1%; obstruction was rare (0.2%). Reflux in either the superficial (saphenofemoral junction) or the deep (femoral or popliteal) venous system was present in the majority (71.0%) of patients with CVI (clinical class ≥C1). Reflux and white race were risk factors for clinical disease; clinical disease, age, female sex, and white race were risk factors for reflux. On the basis of the Caprini score, 14.1% of participants were in the highest risk category for DVT when experiencing a high-risk situation (including 2.2% with history of DVT). CONCLUSIONS Prevalence of clinical CVI and venous reflux is high among health care workers despite a low frequency of cardiovascular comorbidities. Increased awareness about CVI and DVT and preventive strategies for venous disease must be instituted in this high-risk cohort.

Abstract
When commercial sea harvesters have dive accidents, it is sometimes difficult to obtain an accurate dive history and make a definitive diagnosis. We report a sea harvest diver who dived to collect sea snails (Rapana venosa) by using a hookah dive system. He experienced mediastinal and subcutaneous emphysema due to interruption of breathing airflow. Thoracic computed tomography performed one year prior to the accident revealed paramediastinal subpleural blebs on both lung apices. Emphysema was resolved by administering normobaric oxygen.

Abstract
The International Classification of High-resolution Computed Tomography for Occupational and Environmental Respiratory Diseases (ICOERD) has been developed for screening and diagnosis of occupational lung diseases. We evaluated the association of icoerd with the International Labor Organization (ILO) classification and respiratory functions in pneumoconiosis. Chest x-rays of patients with pneumoconiosis were classified with ilo and icoerd using hrct, irregular opacity, pleural pathology, and emphysema was detected in 78, 19, and 53 patients, and using chest x-rays in 47, 4, and 14 patients, respectively. There was a significant correlation between ILO categories and ICOERD grades. There was a negative correlation between ILO categories and FEV1% and FVC%, whereas, ICOERD grades were not correlated with FEV1% and FVC%. HRCT was superior to chest x-rays to detect pneumoconiosis in early stage, but not in evaluating pulmonary functions.

Abstract
Interstitial pulmonary fibrosis is rare clinical entity related to welding usually associated with long term and heavy exposure to welding fumes. A 56-year-old asymptomatic male patient was referred to our clinic due to abnormal chest X-ray findings that was requested for regular controls. He has been working as a welder both indoor and outdoor settings for the last 25 years. The radiological findings were compatible with usual interstitial pneumonia on computed tomography of thorax. Pulmonary function tests, exercise capacity and laboratory results were within normal limits. Collagen tissue markers were negative. In order to confirm the relation of welding with pulmonary fibrosis, bronchoalveolar lavage was performed and stained with Prussian blue. The demonstration of hemosiderin-laden macrophages (25%) confirmed this association and allowed differential diagnosis. Besides it helped the patient decide to leave his job.

Abstract
BACKGROUND: Spontaneous aneurysm of the superficial temporal artery in a helicopter pilot while operating in the extreme cold climatic conditions of a very high altitude area led to a thorough search for etiological possibilities related to this case.CASE REPORT: A 38-yr-old military helicopter pilot, while flying at altitudes ranging from 4500 m to 6000 m (15,000 to 20,000 ft) reported with an acute onset of a subcutaneous swelling on his left temple. History and clinical profile did not suggest any traumatic, hematologic, or vasculitic etiology. His inflammatory markers, anti-nuclear antibody, anti-neutrophil cytoplasmic antibodies, complement levels, and whole-body PET scan did not suggest any evidence of vasculitis. Presence of any other intracranial aneurysms was also ruled out. He underwent curative excision biopsy, which showed perivascular inflammation. He was diagnosed as a case of left superficial temporal artery aneurysm. The recovery period was uneventful and the follow-up color Doppler flow imaging of the temporal artery and acute phase reactants was normal.DISCUSSION: Spontaneous aneurysms involving the superficial temporal artery is a very rare diagnosis. Occurrence of such an aneurysm in a young pilot without any identifiable predisposing factors led the authors to hypothesize a possible etiological combination of environmental and mechanical factors along with aviation stresses with the likely compounding role of the helmet. Management and aeromedical aspects of this unique case are discussed in this paper.Sekhar BM, Sheoran S, Routh D, Sharma S.

Abstract
PURPOSE In the 30 years since the Stockholm Workshop Scale (SWS) was published, the scientific literature on hand-arm vibration syndrome (HAVS) has grown and experience has been gained in its practical application. This research was undertaken to develop an up-to-date evidence-based classification for HAVS by seeking consensus between experts in the field. METHODS Seven occupational physicians who are clinically active and have had work published on HAVS in the last 10 years were asked to independently take part in a three-round iterative Delphi process. Consensus was taken when 5/7 (72%) agreed with a particular statement. Experts were asked to provide evidence from the literature or data from their own research to support their views. RESULTS Consensus was achieved for most of the questions that were used to develop an updated staging system for HAVS. The vascular and neurological components from the SWS are retained, but ambiguous descriptors and tests without adequately developed methodology such as tactile discrimination, or discriminating power such as grip strength, are not included in the new staging system. A blanching score taken from photographs of the hands during vasospastic episodes is recommended in place of self-recall and frequency of attacks to stage vascular HAVS. Methods with the best evidence base are described for assessing sensory perception and dexterity. CONCLUSIONS A new classification has been developed with three stages for the clinical classification of vascular and neurological HAVS based on international consensus. We recommend it replaces the SWS for clinical and research purposes.

Abstract
OBJECTIVES To determine the lung cancer screening yield and stages in a union-sponsored low-dose computerized tomography scan program for nuclear weapons workers with diverse ages, smoking histories, and occupations. METHODS We implemented a low-dose computerized tomography program among 7189 nuclear weapons workers in 9 nonmetropolitan US communities during 2000 to 2013. Eligibility criteria included age, smoking, occupation, radiographic asbestos-related fibrosis, and a positive beryllium lymphocyte proliferation test. RESULTS The proportion with screen-detected lung cancer among smokers aged 50 years or older was 0.83% at baseline and 0.51% on annual scan. Of 80 lung cancers, 59% (n = 47) were stage I, and 10% (n = 8) were stage II. Screening yields of study subpopulations who met the National Lung Screening Trial or the National Comprehensive Cancer Network Group 2 eligibility criteria were similar to those found in the National Lung Screening Trial. CONCLUSIONS Computerized tomography screening for lung cancer among high-risk workers leads to a favorable yield of early-stage lung cancers. Public Health Implications. Health equity and efficiency dictate that screening high-risk workers for lung cancer should be an important public health priority.

Abstract
Individuals with posttraumatic stress disorder (PTSD) show deficits in recruiting neural regions associated with cognitive control. In contrast, trauma exposed individuals (TEIs) show increased recruitment of these regions. While many individuals who experience a trauma exhibit some PTSD symptoms, relatively few develop PTSD. Despite this, no work has examined the relationship between changes in PTSD symptoms and changes in neural functioning in TEIs longitudinally. This study examined the neural correlates of changing PTSD symptom levels in TEIs. Twenty-one military service members completed the affective stroop task while undergoing fMRI within 2 months of returning from deployment and a second scan 6-12 months later. Participants with PTSD or depression at baseline were excluded. PTSD symptom improvement was associated with greater increase in response to incongruent relative to congruent negative stimuli in dorsal anterior cingulate cortex and inferior frontal gyrus/anterior insula and increased BOLD response over time to emotional relative to neutral stimuli in inferior parietal cortex. Improvement in PTSD symptoms were not associated with changes in amygdala responsiveness to emotional stimuli. In short, the current data indicate that TEIs who become more able to recruit regions implicated in cognitive control show greater reductions in PTSD symptom levels.

Abstract
Musicians report a high prevalence of annual musculoskeletal pain (86-89%), attributed to prolonged playing times consisting of repetitive static and dynamic muscle activity. The aim of this study was to explore, compare and synthesise evidence on electromyographic (EMG) muscle activity in neck, shoulder and spinal musculature between painful and asymptomatic instrumental musicians. Ovid, Wiley, Web of Science and Scopus databases were searched in August 2016 for cross-sectional studies that compared EMG activity of neck, shoulder and spinal musculature between musicians with musculoskeletal pain and asymptomatic comparisons. An updated search was performed in May 2017, adding a further study. Two authors independently assessed papers for inclusion and then quality, determined using a modified Downs and Black Checklist. Means and standard deviations were extracted from each study to calculate effect sizes and compare results. Six studies were found to fulfil inclusion criteria. Five studies were deemed high-quality with one being low-quality. Conflicting evidence was found supporting increases in upper trapezius EMG muscle activity in musicians reporting of pain. Moderate-quality evidence indicates increased SCM activity in musicians reporting pain. There was limited evidence supporting increased activity of deltoids, lower trapezius and the upper cervical extensors in musicians reporting of musculoskeletal pain. Meta-analysis of results of three studies assessing upper trapezius activity were conflicting with these not being statistically significant. Further studies with prospective designs, larger population sizes and on broader instrumental groups are warranted.

Abstract
PURPOSE To report the case of a 65-year-old metalworker with no known history of ocular trauma, who suffered from intense ocular pain during magnetic resonance imaging (MRI) of the brain, due to a retained intraocular metallic foreign body (IOFB). CASE REPORT Meticulous ophthalmological examination was inconclusive. An IOFB was confirmed with X-ray scan, whereas its exact localization was enabled by means of ultrasonography and ultrasound biomicroscopy (UBM). CONCLUSIONS Despite appropriate screening protocols, MRI-related ocular complications might occur in the presence of a hidden metallic IOFB. Clinical detection of ocular foreign bodies can sometimes be challenging. Ultrasonography and UBM are valuable adjuncts for the accurate localization, especially of small or hidden particles.

Abstract
We examined the chest CT scans of 1,453 WTC responders using the International Classification of High-resolution CT for Occupational and Environmental Respiratory Diseases. Univariate and bivariate analyses of potential work-related pleural abnormalities were performed with pre-WTC and WTC-related occupational exposure data, spirometry, demographics and quantitative CT measurements. Logistic regression was used to evaluate occupational predictors of those abnormalities. Chest CT scans were performed first at a median of 6.8 years after 9/11/2001. Pleural abnormalities were the most frequent (21.1%) across all occupational groups In multivariable analyses, significant pre-WTC occupational asbestos exposure, and work as laborer/cleaner were predictive of pleural abnormalities, with prevalence being highest for the Polish subgroup (n = 237) of our population. Continued occupational lung disease surveillance is warranted in this cohort.

Abstract
This study draws attention to difficulties in the diagnosis and the understanding of the mechanism of action of mushroom compost worker's lung. Descriptions are given of 4 workers in one factory who developed acute respiratory failure within a 6-month period; 13 others who were unaffected were also studied. Serological investigation appears to be largely unhelpful, and the evidence against the condition being included amongst the extrinsic allergic alveolitides is discussed. A detailed clinical and occupational history is essential for diagnosis.

Abstract
INTRODUCTION Immunocompetent individuals are rarely affected by Aspergillus species and its prime importance lies in immunocompromised patients where it can cause disease, ranging from primarily pulmonary infections to dissemination anywhere in the body. Invasive aspergillosis (IA) occurs in patients with risk factors including prolonged neutropenia, neutrophil dysfunction, patient on cytotoxic drugs, steroid therapy, hematological malignancy, AIDS or in patients with bone marrow transplantation. A recently documented risk factor for IA is the exposure to environmental aspergillus spores at construction sites which makes it an important public health issue. We report here a case of primary CNS aspergillosis in an immunocompetent person who was initially diagnosed as a case of meningioma, and had a history of working in an area with excessive ongoing construction. He had no other primary focus of infection anywhere in the body. He was timely diagnosed and broad spectrum antifungals were started immediately. MATERIAL AND METHODS The brain biopsy and pus sampleas were subjected to direct microscopy using KOH mount and lactophenol cotton blue (LPCB) stain and culture on Sabourad's Dextrose Agar in Microbiology laboratory. Later patient was started on fluconazole and caspofungin. RESULTS Thin, hyaline, septate hyphae on direct microscopy and growth of Aspergillus flavus on SDA culture were observed. The patient improved only with antifungals, without surgery. DISCUSSION This case study highlights the importance of keeping the differential diagnosis of Aspergillus spp. in mind even in individuals with no immunodeficiency. The immunocompetent individuals have better prognosis and if timely diagnosed, can be treated even without surgery. The prevalence of aspergillus spores at construction and demolition sites makes it an important public health issue, hence precautions must be advocated at these sites.

Abstract
BACKGROUND Minor events that occur in the workplace sometimes are evaluated with MRI, which may reveal age-related changes in the symptomatic body part. These age-related changes are often ascribed to the event. However, evidence of similar or worse pathophysiology in the contralateral joint would suggest that the symptoms might be new, but the pathophysiology is not. QUESTIONS/PURPOSES Using a convenience sample of occupational injury claimants with bilateral MRI to evaluate unilateral knee or shoulder symptoms ascribed to a single event at work, we sought to determine whether MRI findings of the shoulder and knee are more often congruent or incongruent with new unilateral symptoms. METHODS Two hundred ninety-four occupational injury claimants employed at companies throughout Texas that do not subscribe to workers' compensation insurance, who were older than 40 years, and with unilateral shoulder or knee symptoms, were studied. Starting in 2012, all patients seen by OccMD Group PA who present with unilateral symptoms ascribed to work undergo bilateral MRI, based on several previous occasions where bilateral MRI proved to be a compelling demonstration that perceived injuries are more likely age-related, previously well-adapted pathophysiology. MRI findings (anything described as abnormal by the radiologist; eg, defect size or signal change) was considered congruent if the abnormality of one or more structures on the symptomatic side was greater than that of the corresponding structures in the asymptomatic joint. Bivariate analysis was used to compare the frequency of MRI findings congruent and incongruent with symptoms. Logistic regression was used to evaluate factors associated with MRI findings of the shoulder or knee. RESULTS Less than half of the patients with shoulder (90 of 189; 48%; p = 0.36) or knee (45 of 105; 43%; p = 0.038) symptoms had worse pathologic features on the symptomatic side. Older age was associated with disorders in the infraspinatus tendon (59 ± 8 versus 56 ± 8 years; p = 0.012), glenoid labrum (60 ± 9 versus 57 ± 8 years; p = 0.025), and biceps tendon (60 ± 8 versus 57 ± 8 years; p = 0.0038). Eighty-seven percent of patients (91 of 105) had structural changes in the medial meniscus described by the radiologist. CONCLUSIONS Occupational injury claimants 40 years of age and older with unilateral knee and shoulder symptoms ascribed to a work event tend to have bilateral age-related MRI changes. Age-related disorders should be distinguished from acute injury. LEVEL OF EVIDENCE Level IV, diagnostic study.

Abstract
Post-traumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) are two of the most common consequences of combat deployment. Estimates of comorbidity of PTSD and mTBI are as high as 42% in combat exposed Operation Enduring Freedom, Operation Iraqi Freedom and Operation New Dawn (OEF/OIF/OND) Veterans. Combat deployed Veterans with PTSD and/or mTBI exhibit deficits in classic executive function (EF) tasks. Similarly, the extant neuroimaging literature consistently indicates abnormalities of the ventromedial prefrontal cortex (vmPFC) and amygdala/hippocampal complex in these individuals. While studies examining deficits in classical EF constructs and aberrant neural circuitry have been widely replicated, it is surprising that little research examining reward processing and decision-making has been conducted in these individuals, specifically, because the vmPFC has long been implicated in underlying such processes. Therefore, the current study employed the modified Iowa Gambling Task (mIGT) and structural neuroimaging to assess whether behavioral measures related to reward processing and decision-making were compromised and related to cortical morphometric features of OEF/OIF/OND Veterans with PTSD, mTBI, or co-occurring PTSD/mTBI. Results indicated that gray matter morphometry in the lateral prefrontal cortex (lPFC) predicted performance on the mIGT among all three groups and was significantly reduced, as compared to the control group.

Abstract
We report the case of a 54-year-old male compressed-air worker with gas bubbles detected by computed tomography (CT). He had complained of strong abdominal pain 30 minutes after decompression after working at a pressure equivalent to 17 meters of sea water for three hours. The initial CT images revealed gas bubbles in the intrahepatic portal vein, pulmonary artery and bilateral femoral vein. After the first hyperbaric oxygen treatment (HBO₂ at 2.5 atmospheres absolute/ATA for 150 minutes), no bubbles were detected on repeat CT examination. The patient still exhibited abdominal distension, mild hypesthesia and slight muscle weakness in the upper extremities. Two sessions of U.S. Navy Treatment Table 6 (TT6) were performed on Days 6 and 7 after onset. The patient recovered completely on Day 7. This report describes the important role of CT imaging in evaluating intravascular gas bubbles as well as eliminating the diagnosis of other conditions when divers or compressed-air workers experience uncommon symptoms of decompression illness. In addition, a short treatment table of HBO₂ using non-TT6 HBO₂ treatment may be useful to reduce gas bubbles and the severity of decompression illness in emergent cases.

Abstract
The International Classification of Radiographs of Pneumoconioses is the scheme worked out by the International Labour Office in Geneva (ILO), to register radiographic chest abnormalities in a well-ordered, reproducible and comparable way. It is used for diagnosing abnormalities caused by dust exposure. Guidelines for the use of the ILO International Classification of Radiographs of Pneumoconioses contain detailed information and recommendations on how to use the classification, as well as how the chest X-ray examination should be performed and recorded. To facilitate the diagnosis of observed abnormalities the classification is completed by the set of standard radiograms illustrating typical irregularities referring to lungs and pleura, included in the classification. The article presents the key information on classification and the most important amendments adopted in the 2000 and 2011 ILO guidelines revisions. These changes refer to radiographs quality assessment, the way of presenting abnormalities registered in standard radiographs (QUAD set, digital images) and registration of failures not related to dust exposure. Particularly important complements result from the development of radiological imaging techniques. They are concerned about the classification of radiographic images of the chest recorded digitally.

Abstract
Hypothenar hammer (HH) syndrome and vibration-induced white finger (VWF) syndrome are the main occupation-related vascular diseases of the upper extremity. The clinical presentation is similar to that of Raynaud’s phenomenon. The characteristic history will lead to the appropriate diagnosis being confirmed by angiographic features in HH and by functional tests in VWF. While in HH the underlying cause, which is mostly thought to be an aneurysm of the ulnar artery, might be cured surgically, in VWF only medical treatment offers relief from the symptoms. The knowledge of these entities is necessary to suspect such disorders so that further exposure to risk factors like repetitive hypothenar trauma or work with vibrating hand-held tools can be avoided, which is of great importance for the overall prognosis of these patients.

Abstract
BACKGROUND Although occupational exposures contribute to a significant proportion of obstructive lung disease, the phenotype of obstructive lung disease associated with work-related organic dust exposure independent of smoking remains poorly defined. OBJECTIVE We identified the relative contributions of smoking and occupational endotoxin exposure to parenchymal and airway remodeling as defined by quantitative computed tomography (CT). METHODS The Shanghai Textile Worker Study is a longitudinal study of endotoxin-exposed cotton workers and endotoxin-unexposed silk workers that was initiated in 1981. Spirometry, occupational endotoxin exposure, and smoking habits were assessed at 5-year intervals. High-resolution computed tomography (CT) was performed in 464 retired workers in 2011, along with quantitative lung densitometric and airway analysis. RESULTS Significant differences in all CT measures were noted across exposure groups. Occupational endotoxin exposure was associated with a decrease (-1.3%) in percent emphysema (LAAI-950), a 3.3-Hounsfield unit increase in 15th percentile density, an 18.1-g increase in lung mass, and a 2.3% increase in wall area percent. Current but not former smoking was associated with a similar CT phenotype. Changes in LAAI-950 were highly correlated with 15th percentile density (correlation -1.0). Lung mass was the only measure associated with forced expiratory volume in 1 sec (FEV1) decline, with each 10-g increase in lung mass associated with an additional loss (-6.1 mL) of FEV1 (p = 0.001) between 1981 and 2011. CONCLUSIONS There are many similarities between the effects of occupational endotoxin exposure and those of tobacco smoke exposure on lung parenchyma and airway remodeling. The effects of occupational endotoxin exposure appear to persist even after the cessation of exposure. LAAI-950 may not be a reliable indicator of emphysema in subjects without spirometric impairment. Lung mass is a CT-based biomarker of accelerated lung function decline.

Abstract
AIM OF THE STUDY The article examines how big German insurance companies handle back pain in terms of occupational health management (OHM). METHODOLOGY Narrative interviews with experts from 8 out of the 20 biggest enterprises were conducted. RESULTS Musculoskeletal diseases are the number one or number two reason for sick leave. All enterprises offer OHM; there is a variety of measures, e. g., sport, massage, advice, ergonomics, healthy food and leadership training. The measures are hardly ever evaluated. DISCUSSION The literature is controversial whether or which OHM measures are effective. In our sample few measures were evaluated; for more evidence based treatment this should be changed.

Abstract
OBJECTIVES The job of firefighting can cause lumbar burden and low back pain. This study aimed to identify the association between age and lumbar intervertebral disc degeneration and whether the association differs between field and administrative (non-field) firefighters. METHODS Subjects were selected using a stratified random sampling method. Firefighters were stratified by geographic area, gender, age and type of job. First, 25 fire stations were randomly sampled considering regional distribution. Then firefighters were stratified by gender, age and their job and randomly selected among the strata. A questionnaire survey and MRI scans were performed, and then four radiologists used Pfirrmann classification methods to determine the grade of lumbar intervertebral disc degeneration. RESULTS Pfirrmann grade increased with lumbar intervertebral disc level. Analysis of covariance showed that age was significantly associated with lumbar intervertebral disc degeneration (p<0.05). The value of β (parameter estimate) was positive at all lumbar intervertebral disc levels and was higher in the field group than in the administrative group at each level. In logistic regression analysis, type of job was statistically significant only with regard to the L4-5 intervertebral disc (OR 3.498, 95% CI 1.241 to 9.860). CONCLUSIONS Lumbar intervertebral disc degeneration is associated with age, and field work such as firefighting, emergency and rescue may accelerate degeneration in the L4-5 intervertebral disc. The effects of field work on lumbar intervertebral disc degeneration were not clear in discs other than at the level L4-5.

Abstract
We report two cases of organizing pneumonia (OP) secondary to the inhalation of the dried tsunami sludge which formed during the 2011 Great East Japan Earthquake and the consequent tsunami. After the disaster, both of these patients had been engaged in the restoration work. About half a month later, they developed shortness of breath and pulmonary infiltrates. These patients were diagnosed with interstitial pneumonia. Their biopsy specimens revealed multifocal peribronchiolitis and OP. An electron probe microanalysis of these specimens demonstrated the presence of elements from the earth's crust in the inflammatory lesions. These two cases indicate that exposure to dried tsunami sludge can cause OP.

Abstract
In workers employed in the aluminum industry, the main harmful production factor is exposure to fluoride salts, which can cause chronic fluoride intoxication. For the assessment of the impact of chronic fluoride intoxication on the development of atherosclerosis, we conducted a comprehensive survey of 87 aluminum-metal makers with chronic fluoride intoxication and 43 aluminum-metal makers without occupational diseases, mean age--52.1 ± 0.4 years. There were considered the presence and severity of atherosclerosis of brachiocephalic arteries, and the arteries of the lower extremities in the studied group, there was evaluated the effect of other risk factors for atherosclerosis (smoking, presence of hypertension, diabetes, dyslipidemia). With the use of Doppler ultrasound of the arteries it was revealed that in metallurgists with chronic fluoride intoxication atherosclerosis was detected in 73.6% versus 55.8% in persons of the comparison group. The performed analysis of the prevalence of main risk factors for atherosclerosis showed that in metal makers with chronic fluoride intoxication in combination with atherosclerosis hypertension is more common (in 54.7%) than in metallurgists with chronic fluoride intoxication without atherosclerosis--only 26.1%. According to the frequency of occurrence of smoking, diabetes mellitus, hypercholesterolemia, and hypertriglyceridemia, there were no significant differences between the metallurgists with chronic fluoride intoxication, with and without atherosclerosis, and the control group, the increase in LDL cholesterol occurs significantly more often in metal-makers with chronic fluoride intoxication in combination with atherosclerosis if compared to workers without occupational diseases. Thus, chronic fluoride intoxication acts as a risk factor in the development of atherosclerosis: atherosclerosis in metal-makers with chronic fluoride intoxication occurs more frequently than in workers who do not have professional pathology. Hypertension and elevated levels of LDL cholesterol were established to increase the relative risk of developing atherosclerosis in metallurgists with chronic fluoride intoxication. At that there are no significant differences in the prevalence of common risk factors for atherosclerosis (smoking, diabetes, hypercholesterolemia, hypertriglyceridemia).

Changes of global and local myocardial contractility of Chernobyl accident clean-up workers (ChA CW) with stable angina were investigated. There were discovered that regular long-term treatment of ChA CW with stable angina using of antiischemic and metabolic drugs promoted to stabilization of global and local myocardial contractility indexes. Ejection fraction, degree of contraction of front-rear systolic left ventricle size, systolic thickness of interventricular septum sufficiently increased. Step-by-step worsening of global and local myocardial contractility indexes in cases of non-regular treatment was taken place. Sufficient differences between indexes of ejection fraction, left ventricle end-diastolic volume, systolic thickness and excursion of interventricular septum in stable angina patients of general population and ChA CW were discovered. Results of global and local myocardial contractility monitoring in ChA CW with stable angina substantiate the advisability of long-term supporting treatment using evidence-based drugs.

Abstract
INTRODUCTION Tasmania's aquaculture industry produces over 40,000 tonnes of fish annually, valued at over AUD500M. Aquaculture divers perform repetitive, short-duration bounce dives in fish pens to depths up to 21 metres' sea water (msw). Past high levels of decompression illness (DCI) may have resulted from these 'yo-yo' dives. This study aimed to assess working divers, using Doppler ultrasonic bubble detection, to determine if yo-yo diving was a risk factor for DCI, determine dive profiles with acceptable risk and investigate productivity improvement. METHODS Field data were collected from working divers during bounce diving at marine farms near Hobart, Australia. Ascent rates were less than 18 m·min⁻¹, with routine safety stops (3 min at 3 msw) during the final ascent. The Kisman-Masurel method was used to grade bubbling post dive as a means of assessing decompression stress. In accordance with Defence Research and Development Canada Toronto practice, dives were rejected as excessive risk if more than 50% of scores were over Grade 2. RESULTS From 2002 to 2008, Doppler data were collected from 150 bounce-dive series (55 divers, 1,110 bounces). Three series of bounce profiles, characterized by in-water times, were validated: 13-15 msw, 10 bounces inside 75 min; 16-18 msw, six bounces inside 50 min; and 19-21 msw, four bounces inside 35 min. All had median bubble grades of 0. Further evaluation validated two successive series of bounces. Bubble grades were consistent with low-stress dive profiles. Bubble grades did not correlate with the number of bounces, but did correlate with ascent rate and in-water time. CONCLUSIONS These data suggest bounce diving was not a major factor causing DCI in Tasmanian aquaculture divers. Analysis of field data has improved industry productivity by increasing the permissible number of bounces, compared to earlier empirically-derived tables, without compromising safety. The recommended Tasmanian Bounce Diving Tables provide guidance for bounce diving to a depth of 21 msw, and two successive bounce dive series in a day's diving.

Abstract
INTRODUCTION The well-digger is a craftsman who hollows wells often manually; this trade can be source of inhalation of the particles of silica. The whole of the radio clinical signs linked to this profession is known under the term "Well-digger's lung". The goal was to study the radio clinical aspects and progression in black African's pulmonological environment. METHODS Retrospective and descriptive study concerning the respiratory involvement of well-diggers in the Pulmonology service of the Teaching Hospital of Bamako, from January 2001 to December 2010. The admission registers were used as data verification support. RESULTS Among 4158 admissions for lung affection, we have collected 39 cases of well-digger's lung (0.9%), all young male adults. The average of exposition period was 13 ± 9 years, correlated to the patient's age (p<0.001). The principal reason of consultation was dyspnea (94.8%). The complications were frequent (cardiac, infectious, pleural). The radiological pictures were made of bilateral big opacities associated with small opacities. The evolution was unfavorable in the majority of the cases. CONCLUSION The well-digger's lung is a young adult pneumoconiosis linked to the inhalation of the particles of silica during the trade (profession) of well-digger that complicates frequently in chronic respiratory insufficiency.

Abstract
The Royal Navy requires reliable advice on the safe limits of escape from a distressed submarine (DISSUB). Flooding in a DISSUB may cause a rise in ambient pressure, increasing the risk of decompression sickness (DCS) and decreasing the maximum depth from which it is safe to escape. The aim of this study was to investigate the pressure/depth limits to escape following saturation at raised ambient pressure. Exposure to saturation pressures up to 1.6 bar (a) (160 kPa) (n = 38); escapes from depths down to 120 meters of sea water (msw) (n = 254) and a combination of saturation followed by escape (n = 90) was carried out in the QinetiQ Submarine Escape Simulator, Alverstoke, United Kingdom. Doppler ultrasound monitoring was used to judge the severity of decompression stress. The trials confirmed the previously untested advice, in the Guardbook, that if a DISSUB was lying at a depth of 90 msw, then it was safe to escape when the pressure in the DISSUB was 1.5 bar (a), but also indicated that this advice may be overly conservative. This study demonstrated that the upper DISSUB saturation pressure limit to safe escape from 90 msw was 1.6 bar (a), resulting in two cases of DCS.

Abstract
BACKGROUND Pneumoconiosis is a form of diffuse interstitial lung disease, often resulting from occupational exposures. As dental prosthetic technicians (DPTs) build prostheses, they are exposed to many chemical materials that increase their risk of developing pneumoconiosis. AIMS To document pulmonary function and prevalence of pneumoconiosis in DPTs. METHODS A cross-sectional study of DPTs working in prosthetic laboratories who underwent pulmonary function test and high-resolution chest computed tomography (HRCT) scanning. RESULTS There were 76 participants and pneumoconiosis was diagnosed in 46%. The most commonly seen radiological finding was round opacities, present in 38%. Agreement among HRCT readers was moderate to good. As defined by HRCT, emphysema was diagnosed more often in those with a longer occupational history or a history of smoking, and low carbon monoxide diffusion capacity (DLCO), but not in those with pneumoconiosis. Forced expiratory rate and DLCO were significantly lower in those who had worked 16 years or more (all P < 0.05). DLCO values were significantly lower in technicians with emphysema and in current smokers (all P < 0.01). Round opacities were also present in a substantial proportion of DPTs who had 15 years or less exposure. Because HRCT is able to detect radiological changes of occupational lung disease very early, the prevalence of pneumoconiosis in our participants was quite high. CONCLUSIONS Pneumoconiosis identified by HRCT was present in almost half of DPTs surveyed. Appropriate education and workplace protection should be given to DPTs in order to prevent exposure to hazardous materials in dental prosthetics laboratories.

Abstract
Ultrasound scanning of main vessels (common carotid, internal carotid, common and superficial femoral, posterior tibial arteries) in staffers of shipyard "Nerpa"--branch of JSC "Shipbuilding center Zvezdochka" (Snezhnogorsk city Murmansk region)--engaged into atomic submarines utilization. Findings are atherosclerotic changes in common carotid and common femoral arteries--increased thickness of intima-media complex over the reference values or atherosclerotic plaque formation. The changes were maximal in a group of males aged over 50 with length of service over 25 years. Discriminant analysis helped to suggest a mathematic model to forecast cardiovascular diseases in personnel of "Nerpa" shipyard.

Abstract
The studies using multiple X-ray methods covered influence of complex containing working process and occupational environment factors on locomotory apparatus of upper limbs and cervical spine in female seamers engaged into various productions. Comparative analysis involved results of regular (standard X-ray) and special X-ray methods (stereoroentgenography, high definition roentgenography, roentgen densitometry, roentgenogrammetry) in 370 examinees with early and moderate clinical symptoms of occupationally mediated diseases of the stated areas. X-ray studies of locomotory apparatus of upper limbs and cervical spine in clothing manufacture workers, with special diagnostic methods, enabled to determine incidence and severity of functional and structural changes more reliably than via standard examination. The changes revealed were assigned mostly in "early" and "moderate" categories and matched with occupational peculiarities of the workers examined.

Abstract
In the study described here, we examined the feasibility of a longitudinal design to measure sonographically swelling of the median nerve caused by controlled exposure to a work task and to evaluate the relationship of changes in morphology to diagnostic standards. Fifteen macaques, Macaca fascicularis, pinched a lever in various wrist positions at a self-regulated pace (8 h/d, 5 d/wk, 18-20 wk). Nerve conduction velocity (NCV) and cross-sectional area (CSA) were measured every 2 wk from baseline through working and a 6-wk recovery. Trending across all subjects revealed that NCV slowed and CSA at the carpal tunnel increased in the working arm, whereas no changes were observed in CSA either at the forearm or for any measure in the non-working arm. There was a small negative correlation between NCV and CSA in the working arm. This study provides validation that swelling can be observed using a longitudinal design. Longitudinal human studies are needed to describe the trajectory of nerve swelling for early identification of median nerve pathology.

Abstract
PURPOSE The aim of the study was to evaluate echocardiographic changes in workers occupationally exposed to low doses of lead. METHODS We enrolled 63 men occupationally exposed to lead into the study (group I). Unexposed group consisted of 49 healthy men (group II). Blood lead concentration (Pb-B) and blood zinc protoporphyrin concentration (ZnPP) were determined. Transthoracic echocardiographic examination was performed. RESULTS In the studied groups, selected on the criterion of occupational exposure to lead, comparative analysis of echocardiographic parameters indicated statistically significant differences. A negative linear correlations between ZnPP and E' was observed in group I. It was proved that a higher concentration of ZnPP is independent risk factor of lowering the E' mean value in group I. CONCLUSIONS Occupational exposure to low doses of lead is associated with the occurrence of discreet morphological and functional heart changes that in the future may predispose to disclosed pathology of heart.

Abstract
X-ray imaging of occupational diseases remains topical so far. Contemporary methods of X-ray imaging of occupational broncho-pulmonary diseases, locomotory disorders and spinal diseases helped to emphasize importance of various X-ray methods combining various approaches in obtaining new X-ray images for better quality of diagnostic and therapeutic measures in occupational therapy. X-ray methods not only widen diagnostic potentialities in occupational therapy, but also can be major methods of in-vivo diagnosis of some occupational diseases.
