OBJECTIVES
In Italy, asbestos was used intensively until its ban in 1992, which was extended for asbestos cement factories until 1994. The aim of this study was to evaluate the dose-response between asbestos exposure and asbestosis mortality across a pool of Italian occupational cohorts, taking into account the presence of competing risks.
METHODS
Cohorts were followed for vital status and the cause of death was ascertained by a linkage with mortality registers. Cause-specific (CS) Cox-regression models were used to evaluate the dose-exposure relationship between asbestosis mortality and the time-dependent cumulative exposure index (CEI) to asbestos. Fine and Gray regression models were computed to assess the effect of competing risks of death.
RESULTS
The cohort included 12,963 asbestos cement workers. During the follow-up period (1960-2012), of a total of 6961 deaths, we observed 416 deaths attributed to asbestosis, 879 to lung cancer, 400 to primary pleural cancer, 135 to peritoneal cancer, and 1825 to diseases of the circulatory system. The CS model showed a strong association between CEI and asbestosis mortality. Dose-response models estimated an increasing trend in mortality even below a CEI of 25 ff/mL-years. Lung cancer and circulatory diseases were the main competing causes of death.
CONCLUSIONS
Asbestos exposure among Italian asbestos-cement workers has led to a very high number of deaths from asbestosis and asbestos-related diseases. The increasing risk trend associated with excess deaths, even at low exposure levels, suggests that the proposed limit values would not have been adequate to prevent disability and mortality from asbestosis.

Right perirenal urinoma and urinothorax in an infant after neonatal ablation of posterior urethral valve: A rare complication diagnosed by pleural aspiration and treated with perinephric drainage: a case report.
OBJECTIVE
Urinothorax and urinoma are rare complications of obstructive uropathy. They might occur due to persistent high back pressure on the renal parenchyma. Urinothorax usually arises while the obstruction exists; in contrast to our case, the child presented after being operated on. He had falsely high creatinine before the operation, which was later explained by creatinine recirculation.
CLINICAL PRESENTATION AND INTERVENTION
We are reporting an uncommon case of late presentation of ruptured urinoma in a 2-month-old Kuwaiti male. It led to urinothorax/uroperitoneum that caused respiratory distress and was associated with creatinine recirculation, requiring retroperitoneal perinephric catheter insertion. The child had recovered and was discharged home.
CONCLUSION
A high index of suspicion is required to diagnose urinothorax, especially in patients with a history of obstructive uropathy. Aspiration of the pleural effusion will guide you to reach the diagnosis. Creatinine recirculation is rarely described in the literature. Having a patient with urinothorax/uroperitoneum should raise the suspicion of falsely elevated creatinine levels.

Comparative Study
BACKGROUND
Nocardia species can affect both immunocompetent and immunocompromised people.
METHOD
This retrospective study, from 2009 to 2022, aims to compare the survival analyses of pulmonary nocardiosis in AIDS and non-AIDS patients in northeastern Thailand.
RESULTS
A total of 215 culture-confirmed cases of pulmonary nocardiosis: 97 with AIDS and 118 without AIDS. The median CD4 count of AIDS patients was 11 cells/µL (range: 1-198), and 33% had concurrent opportunistic infections. 63.6% of 118 non-AIDS patients received immunosuppressive medications, 28.8% had comorbidities, and 7.6% had no coexisting conditions. Disseminated nocardiosis and pleural effusion were more prevalent among AIDS patients, whereas non-AIDS patients revealed more shock and respiratory failure. One hundred-fifty patients underwent brain imaging; 15 (10%) had brain abscesses. Patients with pulmonary nocardiosis have overall 30-day and 1-year mortality rates of 38.5% (95% CI: 32.3%, 45.4%) and 52.1% (95% CI: 45.6%, 58.9%), respectively. The Cox survival analysis showed that AIDS patients with disseminated nocardiosis had a 7.93-fold (95% CI: 2.61-24.02, p < 0.001) increased risk of death within 30 days compared to non-AIDS patients when considering variables such as age, Charlson comorbidity index, concurrent opportunistic infections, duration of illness, shock, respiratory failure, multi-lobar pneumonia, lung abscesses, and combination antibiotic therapy. While AIDS and pulmonary nocardiosis had a tendency to die within 30 days (2.09 (95% CI, 0.74-5.87, p = 0.162)).
CONCLUSION
AIDS with pulmonary nocardiosis, particularly disseminated disease, is a serious opportunistic infection. Early diagnosis and empiric treatment with a multidrug regimen may be the most appropriate approach in a resource-limited setting.

The conventional pretraining-and-finetuning paradigm, while effective for common diseases with ample data, faces challenges in diagnosing data-scarce occupational diseases like pneumoconiosis. Recently, large language models (LLMs) have exhibits unprecedented ability when conducting multiple tasks in dialogue, bringing opportunities to diagnosis. A common strategy might involve using adapter layers for vision-language alignment and diagnosis in a dialogic manner. Yet, this approach often requires optimization of extensive learnable parameters in the text branch and the dialogue head, potentially diminishing the LLMs' efficacy, especially with limited training data. In our work, we innovate by eliminating the text branch and substituting the dialogue head with a classification head. This approach presents a more effective method for harnessing LLMs in diagnosis with fewer learnable parameters. Furthermore, to balance the retention of detailed image information with progression towards accurate diagnosis, we introduce the contextual multi-token engine. This engine is specialized in adaptively generating diagnostic tokens. Additionally, we propose the information emitter module, which unidirectionally emits information from image tokens to diagnosis tokens. Comprehensive experiments validate the superiority of our methods.

Is there a change in the view of treatment for primary spontaneous pneumothorax?: The effect of thoracic CT and autologous blood pleurodesis: a retrospective cohort study.
This study investigated recurrence rates and treatment efficacy based on tomographic findings during a long-term follow-up after primary spontaneous pneumothorax (PSP) treatment. We retrospectively analyzed patients with PSP treated at our hospital between 2003 and 2020. Patients were categorized into 2 groups based on computed tomography (CT) findings: group 1 (no bulla/bleb) and group 2 (bullae-bleb <3 cm). Data on demographics, recurrence, treatment methods, and outcomes were also collected and compared. A total of 251 PSP cases were evaluated, predominantly male (93.6%) with a mean age of 29.23 ± 1.14 years. Most cases (57%) occurred on the right side. Recurrence rates were highest within the first year (77.8%), with the first and second recurrences occurring at rates of 26% and 27.3%, respectively. In group 1 (n = 117), conservative treatment was applied in 15 cases, tube thoracostomy in 81, autologous blood pleurodesis (ABP) in 19, and surgery in 12. Recurrence rates were 46.6%, 21%, 5.3%, and 8.3%, respectively. In group 2 (n = 134), the recurrence rates were 50%, 32.7%, 20%, and 3.1%, respectively (P < .001). No mortality was observed for any patient. The treatment groups included conservative (n = 19), thoracostomy (n = 179), ABP (n = 34), and surgical (n = 44) groups. Recurrence rates were 47.3%, 27.4%, 11.8% (group 1: 5.3%, group 2: 20%, P = .035), and 4.5% (0% vs 6.3%), respectively. ABP effectively reduced recurrence in group 1 PSP patients without bullae or blebs on CT, potentially avoiding surgery. Video-assisted thoracoscopic surgery should be preferred in group 2 cases with bullae or blebs to minimize recurrence. These results underscore the importance of tailoring treatment strategies based on CT findings to optimize PSP management outcomes.

The aim of this study is to delineate the distinctive high-resolution computed tomography features of pulmonary cryptococcosis in non-HIV-infected patients. This retrospective analysis encompasses high-resolution computed tomography scans from 58 patients with histologically confirmed pulmonary cryptococcosis, focusing on the diagnostic challenges and the factors that lead to misdiagnosis. Analysis of computed tomography scans from these patients indicated that nodular or mass-like presentations were evident in 32 cases (55.2%), consolidation presentations in 7 cases (12.1%), and mixed presentations in 19 cases (32.8%). Lesions were predominantly located in the lower lobes of the lungs (40 cases, 69.0%) and in peripheral zones (55 cases, 94.8%). Notable radiographic signs included the presence of the burr sign in 55 cases (94.8%), lobulation sign in 53 cases (91.4%), halo sign in 53 cases (91.4%), and air bronchogram in 46 cases (79.0%). Moreover, 24 cases (41.4%) exhibited necrosis or cavitation, mediastinal lymphadenopathy was noted in 6 cases (10.3%), and pleural effusion was present in 5 cases (8.6%). Lesions were devoid of calcification. Pulmonary cryptococcosis ought to be contemplated in the differential diagnosis when computed tomography imaging exhibits patterns including, but not limited to, lower lobe and peripheral distribution, a broad base abutting the pleura, clustered growth with a propensity for fusion, air bronchogram within lesions, and peripheral halo sign.

Pleural effusion occurs in both benign and malignant pleural disease. In malignant pleural effusions, the diagnostic accuracy and sensitivity of pleural fluid cytology is less than perfect, particularly for the diagnosis of malignant pleural mesothelioma, but also in some cases for the diagnosis of metastatic pleural malignancy with primary cancer in the lung, breast or other sites. Extracellular vesicles (EVs) carry an enriched cargo of microRNAs (miRNAs) which are selectively packaged and differentially expressed in pleural disease states. To investigate the diagnostic potential of miRNA cargo in pleural fluid extracellular vesicles (PFEVs), we evaluated methods for isolating the extracellular vesicle (EV) fraction including combinations of ultracentrifugation, size-exclusion chromatography (SEC) and ultrafiltration (10 kDa filter unit). PFEVs were characterized by total and EV-associated protein, nanoparticle tracking analysis and visualisation by transmission electron microscopy. miRNA expression was analyzed by Nanostring nCounter® in separate EV fractions isolated from pleural fluid with or without additional RNA purification by ultrafiltration (3 kDa filter unit). Optimal PFEV yield, purity and miRNA expression were observed when PFEV were isolated from a larger volume of pleural fluid processed through combined ultracentrifugation and SEC techniques. Purification of total RNA by ultrafiltration further enhanced the detectability of PFEV miRNAs. This study demonstrates the feasibility of isolating PFEVs, and the potential to examine PFEV miRNA cargo using Nanostring technology to discover disease biomarkers.

Chylothorax is accumulation of chyle in pleural space. Causes include traumatic, such as after esophagectomy, and nontraumatic, most commonly malignancy. Lymphoma usually presents as asymptomatic lymphadenopathy, and chylothorax tends to occur late in disease course. Chylothorax as initial presentation of lymphoma is rare with only case reports. We present a case of 43-year-old female who presented with dyspnea only with no B symptoms and found to have left-sided chylothorax, and was later diagnosed to have stage IV follicular lymphoma. This case highlights an atypical presentation of follicular lymphoma, to help physicians to reach diagnosis earlier in similar cases.

Randomized Controlled Trial Comparative Study
BACKGROUND
Nowadays, there is a growing need for competence in bronchoscopy. However, traditional mentorship-based training presents limitations in learning consistency, subjective evaluation, and patient safety concerns. Simulation-based training has gained attention for its potential to enhance skill acquisition and objective assessment. This study explores the effectiveness of self-driven bronchoscopy simulation training using high-fidelity (HFM) and low-fidelity (LFM) models on novice medical students.
METHODS
Medical students without prior bronchoscopy experience were randomly assigned to a self-learn using either HFM or LFM for 4 hours. Pre and posttests were conducted to evaluate the students' knowledge and skill gains with a modified Bronchoscopy Skills and Tasks Assessment Tool. After their test results, students were asked to answer a questionnaire based on a Likert Scale to assess their satisfaction with self-learning.
RESULTS
The results revealed significant progression in both groups, but the HFM group outperformed the LFM group in terms of total score, knowledge, skills, and procedure duration. Participant satisfaction with the educational process was generally high in both groups. However, this study has certain limitations, such as a small sample size, a short training period, and the absence of real evaluation in patients.
CONCLUSION
This study demonstrates the efficacy of self-driven bronchoscopy simulation training using HFM and LFM of bronchoscopy, with HFM offering superior gain for skill and knowledge. Larger-scale and long-term studies are recommended to further investigate the effectiveness of this self-learning and retention of the bronchoscopy knowledge.
