Introduction: Telemedicine is rapidly expanding across various fields worldwide. While it finds application in respiratory diseases due to the imperative need for protection against the risk of transmission and the close monitoring of patients with chronic diseases, there is a scarcity of publications detailing telemedicine experiences in respiratory diseases. This study aims to retrospectively evaluate the prospective management of patients with respiratory diseases through videoconference-based telemedicine, intending to establish a foundation for its judicious application in pulmonology cases.

Materials and methods: In this descriptive study, anonymized medical records of all 478 patients assessed via videoconference-based telemedicine over an eight-month period from June 2020 to February 2021 were reviewed. The analysis included demographic characteristics, disease history, attendance methods, the necessity for in-person physical examination after the initial videoconference (VC) session, the inclusion of investigations, pre-diagnosis, diagnosis processes, follow-up period, and outcomes. Follow-up data for all patients included in the study were reviewed at the end of June 2021.

Result: Median age of the patients was 55 (44-67), with a male predominance of 55%. Approximately 30% resided in a city other than the one in which the physician offering telemedicine was situated. Seventy-nine (16.7%) individuals received telemedicine via VC sessions without the requirement for any in-person examinations. The most prevalent disease among those who applied for telemedicine was asthma. Median duration of the initial VC session was 13 (8-18) minutes. At least half of the individuals seeking videoconference-based telemedicine for chronic respiratory disorders, such as asthma, COPD, and interstitial lung disease, had previously been followed by either the telemedicine provider or another physician in the same hospital. However, the vast majority of telemedicine applications in disease categories such as COVID, post-COVID, pulmonary nodules, and lung cancer were submitted by first-time applicants.

Conclusions: This pioneering study suggests that videoconference-based telemedicine may be an alternative/complementary tool for patients, particularly those with chronic respiratory diseases.

Introduction: Pulmonary thromboembolism (PTE) is a life-threatening disease, with substantial treatment-related complications, difficult follow-up, treatment compliance, and high costs. This study aimed to assess treatment costs with various maintenance therapy regimens, complications, and patient adherence to treatment over a one-year follow-up period.

Materials and methods: This observational, prospective study included 142 patients with PTE who received maintenance anticoagulation therapy between November 2020 and March 2023. The patients were observed at three-month intervals for a year. Possible treatment-related complications, recurrence, mortality, and treatment costs were recorded.

Result: Our results showed that there was no significant difference in bleeding risk based on the drugs used for initial or maintenance treatment. In maintenance therapy, low-molecular-weight heparin (LMWH), warfarin, and direct oral anticoagulant (DOAC) treatment regimens had similar treatment adherence and comparable efficacy and safety in terms of recurrence and bleeding (p> 0.05). Four patients (2.8%) were diagnosed with chronic thromboembolic disease. The one-year mortality rate was 24.6% (n= 35), of which 82.9% (n= 29) occurred within the first three months. Hospital mortality rates with the different maintenance therapies were 8.8% in the LMWH group, 5.7% in the warfarin group, and 3.2% in the DOAC group. The annual cost of using LMWH was higher than that of rivaroxaban, apixaban, and warfarin (p< 0.001) while there was no significant cost difference between DOACs and warfarin (p> 0.05).

Conclusions: In our study, the LMWH, warfarin, and DOAC treatment regimens had similar efficacy, safety, and patient compliance. In terms of cost, LMWH was the costliest while DOAC and warfarin were similar.

Mycosis fungoides is the most commonly seen type of cutaneous T-cell lymphoproliferative disease. While mycosis fungoides is linked to an increased risk of developing secondary malignancies, the occurrence of B-cell-originated disease in association with it is exceedingly rare. A 66-year-old male with persistent papillomatous skin eruption was admitted due to dyspnea. Chest X-ray, positron emission tomography, and chest computed tomography revealed axillary and mediastinal lymph node enlargement and right lower pulmonary lobe infiltration along with right-sided massive pleural effusion. Histological and immunohistochemical findings of pleural biopsy and axillary lymph nodes suggested a diagnosis of pulmonary extranodal marginal zone lymphoma. Skin biopsies from the abdomen, chest, and legs revealed CD4/CD8 double-positive patch stage of mycosis fungoides. After completing six cycles of chemotherapy, complete remission of lymphoma was achieved, with the skin eruptions remaining unchanged. Herein, the authors present a unique case of concomitant diagnoses of mycosis fungoides and marginal zone B-cell lymphoma of the respiratory system to emphasize the importance of careful evaluation of each finding.

Introduction: Vaccines against severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) provide successful control of the coronavirus-2019 (COVID-19) pandemic. The safety and immunogenicity studies are encouraging in patients with inborn errors of immunity (IEI); however, data about mortality outcomes and severe disease after vaccination still need to be fully addressed. Therefore, we aimed to determine the clinical and immunological outcomes of SARS-CoV-2 infection in patients with IEI who have received vaccination.

Materials and methods: Eighty-eight patients with a broad range of molecular etiologies were studied; 45 experienced SARS-CoV-2 infection. Infection outcomes were analyzed in terms of genetic etiology, background clinical characteristics, and immunization history, including the type and number of doses received and the time elapsed since vaccination. In addition, anti-SARS-CoV-2 antibodies were quantified using electrochemiluminescent immunoassay.

Results: Patients were immunized using one of the three regimens: inactivated (Sinovac, Coronavac®), mRNA (BNT162b2, Comirnaty®, Pfizer-Biontech), and a combination. All three regimens induced comparable anti-SARS-CoV-2 IgG levels, with no differences in the adverse events. Among 45 patients with COVID-19, 26 received a full course of vaccination, while 19 were vaccine-naive or received incomplete dosing. No patients died due to COVID-19 infection. The fully immunized group had a lower hospitalization rate (23% vs. 31.5%) and a shorter symptomatic phase than the others. Among the fully vaccinated patients, serum IgM and E levels were significantly lower in hospitalized patients than non-hospitalized patients.

Conclusion: COVID-19 vaccines were well-tolerated by the IEI patients, and a full course of immunization was associated with lower hospitalization rates and a shorter duration of COVID-19 symptoms.

Introduction: Chronic obstructive pulmonary disease is a progressive airway disease that can progress to the terminal stage requiring oxygen supply. In this period, lung volume reduction therapies and/or lung transplantation may be considered. Morbidity and mortality risks due to transplant surgery and posttransplant immunosuppressive therapy show the importance of selecting the best candidates who will benefit from transplantation. In this context, BODE index criteria serve as important markers. This study aimed to analyze the outcomes of lung transplantation in patients with chronic obstructive pulmonary disease and to identify variables that may affect post-transplant clinical outcomes.

Materials and methods: Lung transplants diagnosed with chronic obstructive pulmonary disease performed in our center between March 2013 and January 2023 were included in the study. Demographic information and both pre-op and post-op clinical data of the transplant patients were collected. The effect of BODE index criteria and other pre-transplant clinical data on short- and long-term outcomes after transplantation were investigated.

Results: During the study period, 34 lung transplants were performed for chronic obstructive pulmonary disease. One patient died during the operation, three patients received single transplants, and 30 received double transplants. Post-operative primary graft dysfunction was more common in single transplant recipients. The results were comparable between single and double transplants in terms of post-transplant pulmonary function and the development of chronic lung allograft dysfunction. BODE index criteria had no effect on early and late post-operative clinical data, however intra-operative use of extracorporeal membrane oxygenation, primary graft dysfunction, and prolonged extubation were significantly higher in recipients younger than 60 years.

Conclusion: Our study suggests that prelisting demographic and clinical data of chronic obstructive pulmonary disease patients had no significant effect on post-operative outcomes, however, intra-operative ECMO use, prolonged extubation, primary graft dysfunction (p< 0.05 for each) and chronic rejection (p> 0.05) were more common in patients who are <60 years of age. These data need to be confirmed by larger studies.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUSTBNA) is a minimally invasive diagnostic tool used for the evaluation of mediastinal lymphadenopathy. It is a safe procedure, but complications such as bleeding and infection may occur. We report a case of a patient who developed a subcutaneous abscess abscess and mediastinitis after EBUSTBNA. A 75-year-old male with a history of right nephrectomy due to renal cell carcinoma and lung adenocarcinoma history underwent EBUS-TBNA for the evaluation of a right upper paratracheal lymph node. Two weeks after the procedure, the patient presented to the emergency department with skin induration and erythema on the right clavicular area. A non-contrast neck and thorax CT scan was performed, which revealed an extensive subcutaneous abscess on the right clavicular area, extending to the supraclavicular region. The patient was hospitalized, and empirical intravenous antibiotics were initiated due to deep neck infection. Repeated drainage of the subcutaneous abscess was performed. Bacteriologic examination revealed Streptococcus mitis. The patient showed improvement with antibiotic treatment, and a follow-up ultrasound showed a decrease in the size of the abscess and was discharged approximately four weeks after hospitalization. Although very rare, serious infectious complications may develop after EBUSTBNA, and our case report is an important example regarding its management process.

Introduction: One of COVID-19’s limitations is the reduced quality of life (QoL) caused by variety of underlying reasons. Even though multiple papers in the literature reveal a worsening of QoL after COVID-19, there is currently inadequate evidence on which patients’ QoL is impacted the most. Our study’s aim was to determine which patients’ quality of life was most compromised so that interventions for poor QoL should not be overlooked in the post-disease assessments of those in the risk group.

Materials and methods: Patients referred to our pulmonary rehabilitation center for Long COVID symptoms had their dyspnea perception, body composition, exercise capacity, muscle strengths, and psychological state evaluated. In addition, SF-36 was used to assess their QoL. After obtaining all medical data, the patients were separated into three groups based on whether they had the disease as an outpatient, inpatient in the hospital, or in the intensive care unit. The Anova and Kruskal Wallis tests were utilized in the statistical analysis of demographic data among patient groups. Pearson’s test was used for normal distributions, whereas Spearman’s test was used for non-normal distribution analyses. The factors affecting QoL were investigated using multivariate linear regression analysis.

Results: The majority of 173 study participants had poor QoL. Low exercise capacity (p= 0.026), impaired psychosocial status (p= 0.034 for anxiety, p= 0.022 for depression), and increased fatigue (p= 0.001) were the factors affecting SF-36’s physical component summary (PCS), whereas young age (p= 0.026), male sex (p= 0.037), impaired psychosocial status (p< 0.001 for anxiety, p= 0.002 for depression), and increased fatigue (p= 0.005) were the factors affecting the SF-36’s mental component summary (MCS).

Conclusion: Young age, male sex, reduced exercise capacity, poor psychosocial status, and increased fatigue are predictors for impaired QoL after COVID19. Therefore, non-medical treatment options that improve QoL should be considered in the follow-up of these patients.

Endobronchial solitary papillomas are extremely rare lung neoplasms originating from the bronchial surface epithelium. They often present with cough or recurrent hemoptysis. These tumors are benign, but they should be followed closely because they may even have a low probability of malignant transformation features. It should be kept in mind that malignancy may develop especially if the patient is a smoker. Although the etiology is not known for certain, it is thought to be caused by human papillomavirus in some cases. A 43-year-old male patient was admitted with a complaint of chronic cough. Rigid bronchoscopy was performed for diagnostic and therapeutic purposes after imaging techniques revealed a lesion obstructing the lumen of the right main bronchus. The pathology result was reported as mixed bronchial papilloma. We aimed to present our case because of its rarity and to indicate that chronic cough must be further evaluated.

Introduction: The aim of this study is to develop a model that differentiates between the radiological patterns of severe and mild emphysema using radiomics parameters, as well as to examine the parameters included in the model.

Materials and methods: Over the last 12 months, a total of 354 patients were screened based on the presence of terms such as “Fleischner”, “CLE”, and “centriacinar” in their thoracic CT reports, culminating in a study population of 82 patients. The study population was divided into Group 1 (Fleischner mild and moderate; n= 45) and Group 2 (Fleischner confluent and advanced destructive; n= 37). Volumetric segmentation was performed, focusing on the upper lobe segments of both lungs. From these segmented volumes, radiomics parameters including shape, size, first-order, and second-order features were calculated. The best model parameters were selected based on the Bayesian Information Criterion and further optimized through grid search. The final model was tested using 1000 iterations of bootstrap resampling.

Results: In the training set, performance metrics were calculated with a sensitivity of 0.862, specificity of 0.870, accuracy of 0.863, and AUC of 0.910. Correspondingly, in the test set, these values were sensitivity= 0.848; specificity= 0.865; accuracy= 0.857; and AUC= 0.907.

Conclusion: The logistic regression model, composed of radiomics parameters and trained on a limited number of cases, effectively differentiated between mild and severe radiological patterns of emphysema using computed tomography images.
