RESUMEN
INTRODUCTION: The high morbidity and mortality of tuberculosis has led to the development of numerous therapeutic interventions during the pre-antibiotic era. In 1894, Forlanini proposed the technique of collapse therapy, using spontaneous pneumothorax. In 1926, Bernou developed the oleothorax technique to induce an iatrogenic collapse of the lung through the instillation of oil into the pleural cavity, which was subsequently removed. Nowadays, there are few patients that still represent a living testimony of this historic technique and have been described through traditional radiology. CASE PRESENTATION: We report the case of a patient with evidence of a right oleothorax that was investigated not only with traditional radiology but also with the use of chest ultrasonography. Ultrasounds were able to show peculiar characteristics of the oleothorax, including its particular echogenicity, the rigidity and static nature of the collection, the presence of peripheral calcifications, and the negative impact of the collection on diaphragmatic mobility and excursion. CONCLUSION: To our knowledge, this is the first report of an ultrasound description of oleothorax. We have observed that ultrasound examination, in cases of basal oleothorax, is able to add information regarding its radiological appearance and physiopathological implications on ventilatory mechanics and diaphragmatic distress.

RATIONALE: Osimertinib is the third-generation, pyrimidine-based, irreversible epidermal growth factor receptor-tyrosine kinase inhibitor that received approval from the FDA in November 2015 and has become the standard approach in patients with advanced, epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC), especially with brain metastases. Osimertinib is beneficial in terms of progression-free and overall survival in patients with EGFR-mutated NSCLC. However, the rarity of bilateral pneumothorax among adverse events necessitates further research on its potential fatality rate. PATIENT CONCERNS: A 72-year-old man diagnosed with stage IV (T2NxM1) NSCLC with the 21L858R mutation of the EGFR gene received osimertinib treatment. Unfortunately, 10 weeks after osimertinib treatment, the patient developed severe interstitial lung disease and pneumothorax. Thus, osimertinib treatment was discontinued, and prednisolone (160 mg/day) and supportive treatment were administered. DIAGNOSES: Osimertinib-induced severe interstitial lung disease and pneumothorax. INTERVENTIONS: Osimertinib treatment was discontinued, and prednisolone (160 mg/day) and supportive treatment were administered. OUTCOMES: The bilateral pneumothorax was difficult to correct and the patient eventually died. LESSONS: Osimertinib-induced pneumothorax occurred approximately 10 weeks after receiving the drug and had severe cough and chest tightness as initial symptoms. In addition, the incidence of drug-induced pneumothorax increases in patients treated with osimertinib when combined with underlying respiratory diseases.

Nitrous oxide, commonly known as 'laughing gas', has become a popular recreational drug. Whippets, small canisters containing gas in pressurized form, can be easily obtained from a food store. However, inhaling nitrous oxide from these canisters, which contain a 100% concentration, can lead to hypoxia, resulting in seizures or even death. Inhalation of nitrous oxide rarely causes pneumothorax, pneumomediastinum, and pneumopericardium. This case study highlights the potential dangers of recreational abuse of nitrous oxide.

Anlotinib is a tyrosine kinase inhibitor that targets the vascular endothelial growth factor receptor for the treatment of lung cancer. Pneumothorax is a rare complication of anlotinib treatment. Here, the case of a male patient in his early seventies, with lung cancer combined with emphysema, who developed a pneumothorax during treatment with anlotinib, is described. The patient was admitted to hospital mainly for dyspnoea and was diagnosed with pneumothorax after digital radiography of the chest. The patient's symptoms improved significantly after closed chest drainage, and a repeat chest digital radiography showed a more resolved pneumothorax. The patient had no previous history of pneumothorax. After discontinuation of anlotinib, the latest follow-up chest computed tomography assessment in August 2023 showed no recurrence of pneumothorax, thus, the pneumothorax is presumed to have been associated with anlotinib in this patient. In addition, the authors speculate that emphysema may be a cause of pneumothorax in patients with lung cancer receiving anlotinib treatment. Therefore, clinicians should be alert to the risk of pneumothorax occurrence in patients with emphysema combined with lung cancer who are treated with anlotinib.

BACKGROUND: Pembrolizumab as immunotherapy is increasingly used in adjuvant, neoadjuvant, and standalone therapy and has been described as safe. We share an experience of lung erosion post-thoracic surgery with the use of adjuvant pembrolizumab. CASE PRESENTATION: A 65-year-old Chinese gentleman with metastatic renal cell carcinoma underwent lung metastasis resection and presented with delayed onset pneumothorax while on adjuvant pembrolizumab. Failure of conservative management warranted repeat surgical intervention, and intraoperative findings showed erosion of staple lines possibly caused by poor healing associated with pembrolizumab. CONCLUSION: Adjuvant pembrolizumab may impair wound healing, including stapler line healing. Presentation of delayed pneumothorax in a post-surgical patient undergoing immunotherapy should warrant early surgical intervention.

BACKGROUND: Synthetic cannabinoids are a recreational drug that can cause toxicity with significant side effects. CASE: We report a 21-year-old incarcerated male with a delayed presentation of pneumothorax, pneumomediastinum, and pneumoperitoneum following synthetic cannabinoid use with altered mental status. DISCUSSION: This case not only highlights the need to consider pneumothorax when evaluating synthetic cannabinoid toxicity but it also emphasizes a vulnerable population (incarcerated individuals at risk for trauma, substance use disorders, and mental illness) who are at risk for delayed medical care and poor follow-up.

RATIONALE: Anlotinib is an oral tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor, and has been approved for the treatment of patients with advanced nonsmall cell lung cancer who had received at least 2 previous chemotherapy and epidermal growth factor receptor/anaplastic lymphoma kinase targeted therapy regimens. Pneumothorax is a rare adverse reaction of this drug. Here, we present a case of pneumothorax following anlotinib treatment in a patient with lung cancer. PATIENT CONCERNS: A 61-year-old Asian male long-term smoker was admitted to the hospital in November 2019 with sputum production and dyspnea. DIAGNOSIS: The patient was diagnosed with right lung adenocarcinoma with mediastinal and rib metastases, combined with chronic obstructive pulmonary disease and pulmonary bullous disease. INTERVENTIONS: The patient was treated with oral administration of anlotinib. The patient had a recurrent pneumothorax that improved after drug withdrawal and was free of recurrence. Therefore, pneumothorax caused by rupture of the pulmonary bullous due to anlotinib was considered. OUTCOMES: After discontinuing anlotinib, the patient has not developed pneumothorax to date. LESSONS: Pneumothorax may occur when VEGF is inhibited, which can promote the proliferation and repair of alveolar wall substances, leading to alveolar rupture. With respect to pneumothorax, it is necessary to be aware of the risk of pulmonary bullous rupture during antitumor treatment with small-molecule tyrosine kinase drugs.

To investigate pneumothorax patterns in pazopanib treatment by focusing on the positional relationship between the visceral pleura and metastatic lung tumor, we examined 20 patients with advanced soft tissue tumors who developed lung metastases and underwent pazopanib treatment between 2012 and 2019. Pneumothorax was classified into two types based on the location of the metastatic lesion around the visceral pleural area before pazopanib treatment: subpleural type, within 5 mm from the pleura; and central type, >5 mm from the pleura. We investigated the rates of pneumothorax and the associated risk factors. Five patients experienced pneumothorax (three subpleural and two central types). Cavitation preceded pneumothorax in 83% of patients and led to connection of the cavitated cyst of the metastatic lesion to the chest cavity in the shorter term in patients with the subpleural type. Conversely, a more gradual increase in the cavity size and sudden cyst rupture were observed in the central type. The risk factors for pneumothorax were cavitation after initiating pazopanib and intervention before pazopanib, either ablation or surgery. The location of the metastatic lesions was not a risk factor for the occurrence of pneumothorax. In conclusion, pneumothorax is an adverse event associated with pazopanib treatment. Therefore, attention must be paid to predisposing factors such as the formation of cavitation after pazopanib initiation and previous interventions to the lungs. Moreover, because subpleural pneumothorax tends to occur earlier than the central type, a different time course can be anticipated based on the positional relationships of the metastatic lesions to the visceral pleura.

A young man presented in emergency department with shortness of breath and cough after accidental inhalation of chlorine gas. Initial presentation was unremarkable; therefore, he was kept under observation for 8 hours and was later discharged. After 5 hours, the patient presented again in emergency department with sudden-onset shortness of breath and chest discomfort. On examination, subcutaneous crepitation around the neck and chest was found. Chest and neck X-ray revealed subcutaneous emphysema and pneumomediastinum. CT neck and chest was done, which revealed subcutaneous emphysema and pneumomediastinum and a linear air density in close approximation to right posterolateral wall of trachea at the level of superior margin of sternum was reported. These findings raised the possibility of tracheal injury which was later confirmed by fiberoptic laryngoscopy. The patient was intubated due to hypercapnic respiratory failure resulting from hypoventilation and respiratory distress. Bilateral chest tube insertion was done due to worsening subcutaneous emphysema, high ventilator parameters and prevention of progression to pneumothorax. He was extubated after 5 days; bilateral chest tubes were removed before discharge and underwent uneventful recovery.

This study was performed to investigate pneumothorax characteristics and association with clinical outcomes in patients with osteosarcoma treated with apatinib. We retrospectively reviewed the medical records of osteosarcoma patients treated with apatinib between January 2016 and April 2020 at three institutions. We evaluated the prevalence, healing time, recurrence, severity, clinical management, and prognosis of pneumothorax in these patients. A total of 54 osteosarcoma patients who received apatinib treatment were enrolled in this study. Among them, 14 patients had pneumothorax. There were significant differences between the patients with and without pneumothorax with regard to the cavitating rate of lung metastases (92.86 vs. 32.50%, respectively, P < 0.001), objective response rate (42.86 vs. 10.00%, P = 0.013), disease control rate (85.71 vs. 42.50%, P = 0.006), 4-month progression-free survival (PFS) rate (57.10 vs. 20.00%, P < 0.001), and median PFS (5.65 vs. 2.90 months, P = 0.011). Compared with pneumothorax patients treated with chest tube drainage only [non-staphylococcal enterotoxin C (SEC) group], those treated with chest tube drainage and SEC thoracic perfusion in parallel (SEC group) had a shorter pneumothorax healing time (12.00 ± 4.50 days vs. 24.00 ± 14.63 days for SEC group and non-SEC group, respectively, P = 0.103), a lower recurrence rate of pneumothorax (25.00% vs. 66.67%, P = 0.277), and a longer median PFS (5.9 months vs. 4.75 months, P = 0.964). however, these numerical differences for the SEC/non-SEC data did not reach statistical significance. Pneumothorax and cavitation in lung metastases may be effective prognostic markers for patients with osteosarcoma treated with apatinib. SEC may be effective for treatment of such pneumothorax patients, warranting further study.

Lenvatinib is an inhibitor of tyrosine kinases, such as vascular endothelial growth factor receptor and fibroblast growth factor receptor, and was first approved for use in thyroid cancer in 2015 in Japan. Additional approval was given in March 2018 for its use as a first-line treatment for advanced or unresectable hepatocellular carcinoma. Herein, we report a case of pneumothorax during lenvatinib treatment for multiple lung metastases of hepatocellular carcinoma in a 71-year-old man. Although the development of pneumothorax during treatment with anticancer agents for lung metastases is well-known, this is the first report of pneumothorax induced by lenvatinib during treatment for lung metastases of hepatocellular carcinoma.

Pneumothorax has been reported as a pazopanib-associated adverse event in patients with lung metastases of soft tissue sarcoma (STS). However, pneumothorax triggered by eribulin treatment has never been reported. We herein report two cases of spontaneous pneumothorax in patients with STS treated with eribulin. Both patients experienced pneumothorax accompanied by sudden dyspnea on day 9 or 10 of eribulin treatment. These two cases suggest that spontaneous pneumothorax may occur as an adverse event of eribulin treatment in such patients. We should therefore be alert for the potential development of pneumothorax during eribulin treatment of patients with STS and lung metastases.

RATIONALE: A link is established between air pollution and respiratory diseases. Very few studies evaluated this link with primary spontaneous pneumothorax (PSP). Contrasted results, low statistical power and methodological limits of these studies brought us to evaluate in a more thorough way this link. OBJECTIVES: (1) to estimate the relation between PSP and air pollutants namely nitrogen dioxide (NO2), ozone (O3) and particulate matter with a diameterâ¯≤â¯10⯵m (PM10); (2) to investigate a time lag effect between these pollutants and occurrence of PSP. METHODS: This study has a case-crossover design. Subjects aged ≥18â¯years admitted from 1st June 2009 to 31st May 2013, in 14 Emergency Departments centers on the French territory. Were excluded: patients with traumatic, secondary, recurrent or history of previous pneumothorax. NO2, O3 and PM10 data were collected hourly in monitoring stations. Three exposure assessments were retained: quantitative values, fast increase concentration of air pollutants and peak of pollution. These assessments were calculated for the entire exposure period and for each of the four days of all case and control periods. RESULTS: 948 subjects included. Whatever the pollutant considered, no differences were observed between case and control periods, regardless of whether the quantitative values of air pollutants exposure (pâ¯>â¯0.09), fast increase concentration (pâ¯>â¯0.46) and peak of pollution (pâ¯>â¯0.20). CONCLUSIONS: We failed to show a relation between PSP and short-term air pollution exposure to low levels of NO2 and PM10. An association between O3 exposure and PSP cannot be ruled out. An impact at higher exposure level, and/or a potentiating effect of different meteorological factors remain to be demonstrated.

BACKGROUND: The tyrosine kinase inhibitor pazopanib is used for treatment of sarcoma. Recent studies have suggested that the use of pazopanib may lead to the development of pneumothorax, an unexpected adverse effect in patients with sarcoma metastatic to the chest. METHODS: We conducted a retrospective case control study of patients with sarcoma with metastases to the chest with pneumothorax (cases) and without pneumothorax (controls). The control population was selected from tumor registry in a 1:4 (cases to controls) ratio. The primary outcome of interest was the association between pazopanib and pneumothorax risk in patients with sarcoma metastatic to the chest. Secondary objective was to evaluate risk factors for pneumothorax. RESULTS: We identified 41 cases and 164 controls. Using purposeful selection method the odds of developing pneumothorax while being on pazopanib was not significant in univariate (p = .06) and multivariable analysis (p = .342). On univariate analysis risk factors of pneumothorax in patients with sarcoma were age, male sex, African American race, the presence of cavitary lung nodules/masses, and the presence of pleural-based nodules/masses. On multivariate analysis, only the presence of cavitary lung nodules/masses (P < .001) and the presence of pleural-based nodules/masses (P < .001) remained as risk factors for developing pneumothorax. CONCLUSION: Pazopanib does not increase the risk of pneumothorax in patients with sarcoma and evidence of metastatic disease to the chest. Presence of cavitary lung nodules/masses and the presence of pleural-based nodules/masses were found to be risk factors for pneumothorax.

INTRODUCTION: The targeting of hepatocellular carcinomas (HCC) in the hepatic dome can be challenging during percutaneous thermal ablation (PTA). The aims of this study were (1) to evaluate the safety and efficacy of PTA of HCC in the hepatic dome that cannot be visualized under US, using artificial CO2 pneumothorax and CT-guidance and (2) to compare the results with US-visible HCC located in the liver dome treated under US-guidance. MATERIALS: Over a 32-month period, 56 HCC located in the hepatic dome were extracted from a prospectively maintained database. Twenty-eight cases (US-guidance group) were treated under US-guidance, while the others (n = 28, CT-CO2 group) were treated under CT-guidance using artificial CO2 pneumothorax after lipiodol tagging of the tumor. The primary technical success and complications rates of this technique were retrospectively assessed. Local tumor progression (LTP), intrahepatic distant recurrence (IDR), local recurrence-free survival (LRFS) and overall survival (OS) were also compared between both groups. RESULTS: Primary technical success was 100% in both groups. No major complications occurred. After a median follow-up of 13.8 months (range, 1-33.4 months), LTP occurred in 10.7% (3/28) in CT-CO2 vs. 25% (7/28) in the US-guidance group (p = NS). IDR occurred in 39.3% (11/28) in CT-CO2 vs. 28.6% (8/28) in the US-guidance group (p = NS). Death occurred in 17.9% (5/28) of patients in both groups. LRFS and OS did not significantly differ using Kaplan-Meier survival estimates. CONCLUSION: CT-guided PTA after artificially induced CO2 pneumothorax is a safe and efficient technique to treat HCC located in the hepatic dome.

MDMA (3,4-methylenedioxymethamphetamine) or 'Ecstasy' is an illicit drug frequently used by young people at parties and 'raves'. It is readily available in spite of the fact that it is illegal.1 It is perceived by a lot of young people as being 'harmless', but there have been a few high-profile deaths associated with its use.2 Known side effects of MDMA include hyperthermia, rhabdomyolysis, coagulopathy and cardiac arrhythmias.3 Rarer side effects include surgical emphysema and pneumomediastinum, which have been better described with cocaine abuse.4-6 We present a case of bilateral pneumothorax, surgical emphysema and pneumomediastinum in a young man after taking ecstasy.

We report the case of an 82-year-old woman who developed pneumothorax during treatment for nontuberculous mycobacterium (NTM). In year X, she was diagnosed with NTM at another hospital after abnormalities were pointed out on a chest X-ray. She received no treatment for NTM at that time. Antibiotic treatment was introduced at the department of respiratory medicine in our hospital in year X+15. The regimen was composed of clarithromycin (800 mg/day), ethambutol (750 mg/day) and rifampicin (600 mg/day); however, treatment with the three-drug antibiotic regimen was canceled at her request and changed to erythromycin. She was then referred to our department. However, right-side cavity wall thickening was detected on chest CT in year X+17.We resumed clarithromycin (600 mg/day), ethambutol (750 mg/day) and rifampicin (450 mg/day). On the 43rd day after treatment with three types of antibiotics, she felt dyspnea and she was admitted to the hospital and was diagnosed with right-side pneumothorax. The pneumothorax was thought to have been caused by a break in the adhesion of the cavity wall. The visceral pleura was weakened by the exacerbation of NTM and the thickness of the cavity wall was improved after the resumption of antibiotic therapy. This report is considered to be an important case in which pneumothorax developed as a complication in an elderly patient during treatment for NTM.
