Pulmonary light chain deposition disease is a rare entity characterized by immunoglobulin deposition within the lung parenchyma with pathologic features distinct from pulmonary amyloidosis. Here, the authors present the clinical presentation, associations, and radiologic features of pulmonary light chain deposition disease in a series of 4 patients as well as discuss the distinctions from amyloidosis. The present case series highlights the frequent presence of both cysts and nodules at CT. Clinically, lymphoma and/or autoimmune disease are often associated.

BACKGROUND: To equip radiographers to tackle the negative impacts of climate change, it is crucial to offer in-depth education on planetary health and sustainability. This study aimed to use a tertiary institution in Zimbabwe as a case study to assess radiography students\' views on the integration of sustainability into their curriculum.
METHODS: A quantitative cross-sectional study using a questionnaire took place at a tertiary institution in Harare, Zimbabwe, where students were sampled consecutively. Categorical variables were described using frequencies and percentages. Data analysis was carried out using Stata 13.1.
RESULTS: A total of 96 out of 111 students participated, with an 86% response rate. The majority of students believed in the importance of environmentally friendly radiography practices (90.62%) and felt that sustainability is crucial for better patient care. While sustainability teaching was acknowledged in the curriculum, many students were not confident about the topic in exams. There was no consensus on the preferred methods of teaching sustainability. University lecturers specializing in climate-related fields were seen as the most suitable teachers for sustainability education.
CONCLUSIONS: The curriculum reflects efforts in sustainability education, but student confidence and awareness of climate-focused research units require improvement. Continuous education is crucial to link sustainability awareness with practical implications in radiography. Future studies should investigate tailored teaching methods to engage students effectively in sustainable radiography practices.
CONCLUSIONS: The findings highlight the importance of ongoing education and awareness campaigns to address the disconnect between understanding the importance of sustainability and implementing it effectively in radiography practice.

OBJECTIVE: Health technology assessment (HTA) is a systematic process used to evaluate the properties and effects of healthcare technologies within their intended use context. This paper describes the adoption of HTA process to assess the adoption of the EOSedge™ system in clinical practice.
METHODS: The EOSedge™ system is a digital radiography system that delivers whole-body, high-quality 2D/3D biplanar images covering the complete set of musculoskeletal and orthopedic exams. Full HTA model was chosen using the EUnetHTA Core Model® version 3.0. The HTA Core Model organizes the information into nine domains. Information was researched and obtained by consulting the manufacturers\' user manuals, scientific literature, and institutional sites for regulatory aspects.
RESULTS: All nine domains of the EUnetHTA Core Model® helped conduct the HTA of the EOSedge, including (1) description and technical characteristics of the technology; (2) health problem and current clinical practice; (3) safety; (4) clinical effectiveness; (5) organizational aspects; (6) economic evaluation; (7) impact on the patient; (8) ethical aspects; and (9) legal aspects.
CONCLUSIONS: EOS technologies may be a viable alternative to conventional radiographs. EOSedge has the same intended use and similar indications for use, technological characteristics, and operation principles as the EOS System and provides significant dose reduction factors for whole spine imaging compared to the EOS System without compromising image quality. Regarding the impact of EOS imaging on patient outcomes, most studies aim to establish technical ability without evaluating their ability to improve patient outcomes; thus, more studies on this aspect are warranted.

UNASSIGNED: Femoral and tibial fractures may result in delayed union and nonunion, posing significant challenges in orthopedic practice. The Ilizarov technique has emerged as a promising solution for managing these complex cases.
UNASSIGNED: Evaluate the radiographic and functional results of Ilizarov fixation in the treatment of nonunion of tibia and femur fractures.
UNASSIGNED: Retrospective.
UNASSIGNED: Hospitals affiliated with a university hospital.
UNASSIGNED: Patient demographics, fracture characteristics, and treatment details were analyzed for the period from October 2015 to September 2022 in patients who were treated for nonunion of the tibia and femur using the Ilizarov fixator. Clinical and radiological assessments were performed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. The study focused on assessing the average duration for union and frame removal, bone results, successful union rates, and functional results using the ASAMI criteria, obtaining data from the existing medical records, spanning various medical facilities treating nonunion fractures.
UNASSIGNED: 126 patients.
UNASSIGNED: The average duration for union and frame removal was 8 months, with excellent bone results observed in 60.32% of cases. Out of 126 patients, 118 achieved successful union, while there were 2 failure cases necessitating amputation (1.52%). Functional results revealed excellent outcomes in 39.68% of cases. Complications included pin tract infections, ankle and knee stiffness, and limb shortening. External fixation duration and infection eradication were consistent with previous research, emphasizing the technique\'s effectiveness.
UNASSIGNED: The Ilizarov technique proved highly effective in managing nonunion tibia and femur fractures, offering favorable outcomes in terms of union, infection control, pain relief, and functional recovery. While excellent bone outcomes do not guarantee optimal function, this method remains a reliable approach for complex cases.
UNASSIGNED: Potential biases inherent in retrospective analyses and the need for further randomized controlled trials to comprehensively compare treatment modalities.

METHODS: We report a case of an intramuscular thigh hemangioma in a 19-year-old woman with a several year history of atraumatic thigh pain. Radiographs obtained by her primary care physician demonstrated periosteal bone reaction, prompting referral to Orthopaedic Oncology department. The patient had successful symptomatic management with propranolol.
CONCLUSIONS: The case highlights the diagnosis and potential treatments. In a stepwise approach to care for symptomatic benign vascular lesions, propranolol has been a proven therapeutic option and may be a useful first-line therapy for symptomatic hemangiomas.

OBJECTIVE: We created an infrastructure for no code machine learning (NML) platform for non-programming physicians to create NML model. We tested the platform by creating an NML model for classifying radiographs for the presence and absence of clavicle fractures.
METHODS: Our IRB-approved retrospective study included 4135 clavicle radiographs from 2039 patients (mean age 52 ± 20 years, F:M 1022:1017) from 13 hospitals. Each patient had two-view clavicle radiographs with axial and anterior-posterior projections. The positive radiographs had either displaced or non-displaced clavicle fractures. We configured the NML platform to automatically retrieve the eligible exams using the series\' unique identification from the hospital virtual network archive via web access to DICOM Objects. The platform trained a model until the validation loss plateaus. Once the testing was complete, the platform provided the receiver operating characteristics curve and confusion matrix for estimating sensitivity, specificity, and accuracy.
RESULTS: The NML platform successfully retrieved 3917 radiographs (3917/4135, 94.7 %) and parsed them for creating a ML classifier with 2151 radiographs in the training, 100 radiographs for validation, and 1666 radiographs in testing datasets (772 radiographs with clavicle fracture, 894 without clavicle fracture). The network identified clavicle fracture with 90 % sensitivity, 87 % specificity, and 88 % accuracy with AUC of 0.95 (confidence interval 0.94-0.96).
CONCLUSIONS: A NML platform can help physicians create and test machine learning models from multicenter imaging datasets such as the one in our study for classifying radiographs based on the presence of clavicle fracture.

Transphyseal fractures of the distal humerus are usually seen in children younger than 3 years of age and are considered as Salter-Harris Type I epiphysiolysis. Neonatal transphyseal distal humerus injuries are extremely rare. It usually occurs due to trauma during difficult labour but can also be seen after child abuse. Since the distal humerus is composed of cartilaginous tissue in newborns, it is difficult to make a diagnosis with direct radiography. Patients are often diagnosed with elbow dislocation. However, elbow dislocation is almost never seen under the age of 3 years. Transphyseal fractures can be seen as a result of manoeuvres performed to deliver the baby during difficult normal delivery. Transphyseal humeral injuries can also be seen after caesarean section, child abuse and falling on the hyperextended arm. Clinical symptoms include pain, swelling, ecchymosis and crepitation at the elbow. Pseudoparalysis is present due to pain. In children with a history of difficult birth or trauma, evaluation with direct radiography should be performed initially. Radiocapitellar line is distorted on radiographs and the elbow joint appears subluxated. The treatment algorithm for transfusional humeral fractures in neonates is varied. It should be remembered that patients in this age group have a tremendous healing capacity. In conservative treatment, 2-4 weeks of follow-up with a long-arm splint after reduction is sufficient. In addition, closed reduction-internal fixation or open reduction-internal fixation can be applied according to the amount of displacement of the fracture. Cubitus varus, osteonecrosis, growth disturbance, decreased range of motion, compartment syndrome, neurovascular injury and infection are the main complications seen after transfusional humeral fractures.

The nasopharynx is a rare anatomical location where a foreign body may become lodged after being ingested or inhaled. We are presenting a rare case of nasopharyngeal foreign body impaction in a two-and-a-half-year-old child that had been missed for almost a year. The child presented with a history of right-sided foul-smelling nasal discharge, snoring and mouth breathing. An X-Ray soft tissue lateral view of the post-nasal space showed an irregular partially radiopaque nasopharyngeal foreign body. The removal of the foreign body was performed under general anaesthesia successfully. Foreign body impaction in the nasopharynx can easily be missed and it is important to keep this region in mind when dealing with missing inhaled or ingested foreign bodies.

BACKGROUND: Total hip arthroplasty (THA) is the gold standard procedure for patients with end-stage osteoarthritis after failed conservative therapy. Digital templating is commonly employed in preoperative preparation for THA and contributes positively to its outcome. However, the impact of coxa valga and antetorta (CVA) configurations on stem size prediction accuracy remains not reported. Previous studies demonstrated that the size of the lesser trochanter (LT) can be used to determine femoral anteversion on pelvis radiographs. This study investigates the accuracy of preoperative digital templating in predicting stem size in patients with CVA undergoing cementless THA.
METHODS: Preoperative radiographs of 620 patients undergoing cementless THA were retrospectively investigated. Radiographs were standardized with patients standing and the leg internally rotated by 15°. A CVA group was established including patients with a CCD angle greater than 140° and a lesser trochanter (LT) size of at least 10 mm for men and 8 mm for women. For the control group, radiographs with a CCD angle ranging from 125-135° and LT size 3-10 mm for men and 3-8 mm for women were selected. Preoperative templating was performed using mediCAD. To reduce confounding factors, case-control matching was carried out for BMI and body height.
RESULTS: After case-control matching, a total of thirty-one matches were analyzed. Stem size was underestimated in 74% (23/31) in the CVA and 13% (4/31) in the control group (p < 0.001). Moreover, patients with CVA were more likely to be underestimated by two sizes compared to controls (p < 0.004). In contrast, the exact stem size was predicted more frequently in the control group (p < 0.001).
CONCLUSIONS: Stem size in patients with a CVA configuration are at high risk of being underestimated when using digital templating. These findings can be valuable for guiding in intraoperative decisions and lowering the risk of complications associated with an undersized femoral component.

BACKGROUND: Evaluating isolated extremity discomfort can be challenging when initial imaging and exams provide limited information. Though subtle patient history hints often underlie occult pathologies, benign symptoms are frequently miscategorized as idiopathic.
METHODS: We present a case of retained glass obscuring as acute calcific periarthritis on imaging. A 48-year-old White male with vague fifth metacarpophalangeal joint pain had unrevealing exams, but radiographs showed periarticular calcification concerning inflammation. Surgical exploration unexpectedly revealed an encapsulated glass fragment eroding bone. Further history uncovered a forgotten glass laceration decade prior. The foreign body was removed, resolving symptoms.
CONCLUSIONS: This case reveals two imperative diagnostic principles for nonspecific extremity pain: (1) advanced imaging lacks specificity to differentiate inflammatory arthropathies from alternate intra-articular processes such as foreign bodies, and (2) obscure patient history questions unearth causal subtleties that direct accurate diagnosis. Though initial scans suggested acute calcific periarthritis, exhaustive revisiting of the patient\'s subtle decade-old glass cut proved pivotal in illuminating the underlying driver of symptoms.
CONCLUSIONS: Our findings underscore the critical limitations of imaging and the vital role that meticulous history-taking plays in clarifying ambiguous chronic limb presentations. They spotlight the imperative of probing even distant trauma when symptoms seem disconnected from causative events. This case reinforces the comprehensive evaluation of all subtle patient clues as key in illuminating elusive extremity pain etiologies.
