Foreign body (FB) aspiration is an infrequent cause of respiratory distress in adults. Advancing age, central nervous system disorders or trauma, drug or alcohol addiction, neuromuscular diseases, and mental health issues and illnesses are the main risk factors. The authors present an atypical clinical presentation of a 3-week-lasting foreign body aspiration mimicking a tumour that led to severe acute respiratory insufficiency and required aggressive artificial lung ventilation. Diagnosis of FB was based on the results of the chest computed tomography (CT) scans and flexible bronchoscopy, which, however, initially assumed a neoplastic disease in the right main bronchus. During FB extraction via flexible fiberoptic bronchoscopy inserted through an 8.5 mm endotracheal tube high-frequency ventilation through a catheter placed between the vocal cords was used to ensure adequate alveolar ventilation and maintain sufficient oxygenation. After extraction of the FB, thoracosurgical intervention was performed to resolve empyema as a septic complication of the FB aspiration. After this therapy, a complete resolution of pleural empyema and lung atelectasis was observed.

An 82-year-old woman with COPD presented to the emergency department with cough, increasing sputum production, wheezing, and worsening shortness of breath for two weeks. On imaging studies, the patient was found to have a right upper lobe spiculated nodule and an endobronchial lesion with near total occlusion of the right lower lobe bronchus with sub-segmental atelectasis. Bronchoscopy with EBUS-TBNA of subcarinal and right hilar lymph nodes revealed lung cancer with clear cell phenotype. Given the predominance of clear cell morphology, the diagnosis of metastatic renal or ovarian cancer was entertained. However, there was no evidence of renal or ovarian lesions on the PET-CT scan, ruling out the possibility. Salivary gland type lung cancer (STLC), which is responsible for less than 1% of all lung cancer cases in adults, was also considered. The two distinct STLCs that may have similar morphologic appearances are hyalinizing clear cell carcinoma (HCCC) and mucoepidermoid carcinoma (MEC). The other type of tumour in the lung that demonstrates a clear cell phenotype is perivascular epithelioid cell neoplasms or PEComa, which are mesenchymal in origin. Immunohistochemical staining was strongly positive for p63, CK5/6, CK7, CK-LMW, and negative for TTF-1, Napsin A, p16, and CK20. Additional staining, including HMB-45, S-100, and mucicarmine, were also negative. Next-generation sequencing for the salivary gland fusion panel, including EWSR1-ATF1 fusion and EWSR1 gene rearrangement for HCCC and MAML2 gene rearrangements for MEC, was negative. She was diagnosed with non-small cell lung cancer favouring squamous cell carcinoma with clear cell phenotype, a rare entity.

OBJECTIVES
The prevalence of respiratory infectious diseases has changed in the post-COVID-19 epidemic era, and mycoplasma pneumoniae (MP) infection in children has attracted wide attention.
METHODS
Children hospitalized for pneumonia in Wuhan, China, in 2023 were enrolled. Respiratory secretions were obtained for the targeted next-generation sequencing (tNGS) including mutation of MP. Pulmonary inflammation was divided into bronchopneumonia and pulmonary consolidation/atelectasis according to lung computed tomography imaging.
RESULTS
Of the 667 pediatric pneumonia, 478 were MP positive (72%). The positive rate of MP detected by tNGS increased from April, and MP had become the primary pathogen of pneumonia in children in 2023. The 23S rRNA mutations were all A2063G, accounting for 85% of detected MP. The clinical symptoms of the mutant and wild-type strains were similar, with half of them experiencing atelectasis and lung consolidation. Early bronchoscopic lavage combined with azithromycin in pediatric pulmonary consolidation was an effective therapy strategy, which could be an alternative selection to MP pneumonia treatment.
CONCLUSIONS
A2063G mutant strain MP was the primary pathogen of mycoplasma pneumoniae in children recently, which was often complicated by extra-pulmonary symptoms and complications.

Re-expansion pulmonary edema is defined as pulmonary edema that occurs when a chronically collapsed lung rapidly re-expands, most commonly following chest tube placement for pneumothorax, re-expansion of severe atelectasis, and evacuation of pleural effusion. Though it is very rare, the sudden onset and clinical features of re-expansion pulmonary edema make it a lethal complication that requires urgent treatment. We present a 60-year-old patient who underwent an aortic valve replacement with pre-existing large bilateral pleural effusions. Intraoperatively, upon evacuation of the pleural effusions, the patient developed worsening lung compliance, refractory hypoxemia, and hypercapnia that required emergent veno-venous extracorporeal membrane oxygenation support.

Comparative Study
Comparative analysis of pulmonary ventilation distribution between low-cost and branded incentive spirometers using electrical impedance tomography in healthy adults: Study protocol.
BACKGROUND
The Incentive Spirometer (IS) increases lung volume and improves gas exchange by visually stimulating patients to take slow, deep breaths. It prevents respiratory complications and treats postoperative atelectasis in patients undergoing abdominal, thoracic, and neurosurgical procedures. Its effectiveness has been validated in studies that support improved lung capacities and volumes in individuals with respiratory complications, postoperative thoracic surgery, upper abdominal surgery, and bariatric surgery. The modified Pachón incentive spirometer (MPIS) is a cost-effective alternative to branded IS. It is crucial to validate whether the MPIS distributes ventilation as effectively as commercial devices do. Ventilation distribution will be measured using electrical impedance tomography.
OBJECTIVE
The aim is to compare the distribution of pulmonary ventilation between the MPIS and another commercial IS in healthy adults using electrical impedance tomography.
METHODS
A crossover clinical trial is proposed to evaluate the measurement of pulmonary ventilation distribution using EIT in a sample of healthy adults. All participants will use a commercial flow IS and the MPIS, with the order of assignment randomized. This research will use electrical impedance tomography to validate the operation of the MPIS.
CONCLUSIONS
This study protocol will compare two incentive spirometers' impact on pulmonary ventilation, potentially endorsing the adoption of a cost-effective device to enhance accessibility for targeted populations.
TRIAL REGISTRATION
The study was registered in ClinicalTrials.gov (NTC05532748).

Randomized Controlled Trial
[Effects of injection on intrapulmonary shunt and blood IL-6 and TNF-α levels during single lung ventilation in patients undergoing radical resection of esophageal cancer].
OBJECTIVE
To explore the effects of Rhodiola rosea injection on pulmonary shunt and serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels during single lung ventilation in patients undergoing radical resection of esophageal cancer.
METHODS
Forty-six patients undergoing radical operation for esophageal cancer were randomized equally into control group and Rhodiola rosea injection group. In the Rhodiola group, 10 mL of Rhodiola rosea injection was added into 250 mL of normal saline or 5% glucose solution for slow intravenous infusion, and normal saline of the same volume was used in the control group after the patients entered the operation room. At T, T and T, PaO of the patient was recorded and 2 mL of deep venous blood was collected for determination of serum TNF-α and IL-6 levels. The incidence of postoperative atelectasis of the patients was recorded.
RESULTS
Compared with those in the control group, the patients receiving Rhodiola rosea injection had significantly higher PaO and Qs/Qt at T and T (<0.05) and lower serum IL-6 and TNF-α levels at T (<0.05). No significant difference in the incidence of postoperative atelectasis was observed between the two groups (>0.05).
CONCLUSION
Rhodiola rosea injection before anesthesia induction can reduce intrapulmonary shunt during single lung ventilation, improve oxygenation, reduce serum IL-6 and TNF-α levels, and alleviate intraoperative lung injury in patients undergoing radical resection of esophageal cancer.

BACKGROUND
Malignant airway obstruction (MAO) secondary to tumor growth occurs in nearly a third of patients with lung cancer and portends a very poor prognosis if untreated. Treatment options include bronchoscopic intervention with tumor debulking, stent placement, endobronchial brachytherapy, or palliative radiotherapy.
CASE REPORT
This is a report of a 74-year-old woman with a medical history of metastatic lung adenocarcinoma, hospitalized for dyspnea, hemoptysis, and chest pain with a radiographic finding of MAO on chest X-ray and computed tomography. Patient underwent radiation with a total dose of 13 Gy in two once-weekly fractions of 6.5 Gy per fraction. Three days after the end of radiation treatment, chest X-ray showed a completely right lung re-expansion without atelectasis. Two weeks after radiotherapy treatment, the patient was discharged from hospital without pulmonary symptoms.
CONCLUSION
A different fractionation with a lower equivalent dose in 2 Gy fraction compared to literature data showed efficacy in resolving MAO with excellent local control in the first three months of follow-up.

Silent sinus syndrome is a rare clinical entity affecting the maxillary sinus, characterized by ipsilateral enophthalmos and hypoglobus. Its etiology and pathophysiology are still debated. It is diagnosed by clinical examination and confirmed with computed tomography. It is commonly managed surgically. We present the case of a 34-year-old woman with silent sinus syndrome treated with a patient-specific implant for orbital reconstruction, functional endoscopic sinus surgery approach, intraoperative scan, and surgical navigation, successfully restoring orbital volume and sinus ventilation.

BACKGROUND
The risk of morbidity and mortality in the group of people qualified for kidney transplantation is high. Although currently, the qualification for kidney transplantation is very extensive and detailed, the final examination and assessment at the transplant center is crucial for the success of the transplantation.
CASE REPORT
A 50-year-old woman with end-stage kidney disease was admitted to the Department of General, Vascular, and Transplant Surgery on July 21, 2023, for kidney transplantation. A month earlier, she had undergone surgery to create an arteriovenous fistula on the left forearm. The regional anesthesia was performed. Apart from temporary pain and cough, the postoperative course was uncomplicated. Upon admission to the Department, the patient was in good general condition, and only a dry cough was noted during the physical examination. Chest X-ray revealed pneumothorax on the left side with partial lung atelectasis. The patient was temporarily disqualified from kidney transplantation and the pneumothorax was cured. She is currently on the active list waiting for a kidney transplant.
CONCLUSIONS
The analysis of the above case emphasizes the importance of a physical examination and final qualification at the transplant center. Detailed examination and evaluation at the above center can improve patients' quality of life and survival.

Successful Management With Continuous Negative Abdominal Pressure Therapy in a Severely Obese Patient With Inhalation Burn-Induced Severe Respiratory Failure Requiring Veno-Venous Extracorporeal Membrane Oxygenation: A Case Report.
Continuous negative abdominal pressure (CNAP) therapy effectively provides respiratory support in patients with respiratory failure and severe obesity; however, its use in clinical practice remains limited. In this case, we report a significant improvement in the respiratory condition of a patient with severe obesity and inhalation burns following the application of CNAP in addition to venovenous extracorporeal membrane oxygenation (V-V ECMO) and mechanical ventilation. The patient was able to wean off these devices successfully. This case highlights the potential of CNAP therapy as an adjunct treatment for severe respiratory failure, particularly in obese patients for whom conventional interventions are insufficient.
