An uncommon clinical case of an adult woman who was referred to the hospital with severe symptoms attributable to cystic echinococcosis (CE) is described in this report. According to a questionnaire, the subject was exposed to a high risk of infection since she was employed on a farm about 20 years before diagnosis. She lived close to several animal species and handled vegetables in inadequate hygienic conditions. Medical and laboratory investigations confirmed the presence of massive echinococcal cystic lesions in each lung and in the liver. Given the peculiarity of the case, pharmacological and surgical treatments were the only conceivable option. The association of pharmacological treatment, surgery, and interventional radiology procedure represented a reliable and effective way to handle a complex case of human hydatidosis. A multi-disciplinary approach was mandatory, resulting in a clear and conclusive diagnosis of CE caused by the zoonotic parasite E. granulosus sensu stricto of the G1 genotype.

Introduction: Exhaled breath condensate (EBC) sampling has been suggested as a less-invasive and cost-effective method to detect biological macromolecules, including miRNA. To explore the feasibility of its use as a biomarker of early effects of asbestos exposure, we conducted a preliminary test on male volunteers by comparing the miRNA profile in the EBC and the plasma using 2 different sequencing platforms. Methods: Six male volunteers, all retired and unexposed to dust or fumes, participated in the test. RNA was extracted from 200 μL EBC samples and same-size plasma samples. Sample aliquots were processed in 2 laboratories using 2 different sequencing platforms: a MiSeq Illumina® platform and a more performing HiSeq Illumina® platform. Results: The HiSeq3000® sequencing platform identified twice as many unique molecular indexes (UMI)-validated miRNA as the MiSeq® platform. The Spearman's correlation coefficient between EBC counts and plasma counts was significant in 5/6 subjects with either platform (MiSeq® = 0.128-0.508, P =.026-<.001; HiSeq® = 0.156-0.412, P =.001-<.001). The intraclass correlation coefficient confirmed the consistency of the miRNA profile over the 6 participants with both biospecimens. Exploring the agreement between the EBC and plasma samples with Bland-Altman plots showed that using the HiSeq3000® platform substantially improved the EBC miRNA detection rate. Conclusion: Our preliminary study confirms that, when using the HiSeq® sequencing platform, EBC sampling is a suitable, non-invasive method to detect the miRNA profile in healthy subjects.

Background: Mediastinal hemangiomas are rare, and their etiology remains unclear. Most patients affected have no pathognomonic clinical symptoms, and the diagnosis is often incidental. Due to the paucity of the available literature regarding the management of this disease, the choice and timing of treatment remains controversial. Case presentation: Herein, we report the case of a hemangioma of the azygos vein arch in a 66-year-old woman who presented with dyspnea, chest discomfort, dysphagia, and weight loss. A simultaneous right chylothorax refractory to conservative management was found. A CT-guided biopsy of the mass was performed, and it confirmed the vascular nature of the lesion. Therefore, the patient underwent an angiography followed by endo-vascular embolization. Three days later, thoracoscopic surgical resection of the mass and the repair of the chyle leakage were performed safely. The patient was discharged uneventfully on postoperative day seven, with complete resolution of all the presenting symptoms. Conclusions: Treatment of symptomatic mediastinal hemangiomas could be mandatory, but a thorough multidisciplinary approach to these rare malformations is essential. Despite the risk of intraoperative bleeding, selective endovascular embolization followed by thoracoscopic surgery allowed for a complete and safe resection with a good outcome.

Background: Persistent air leak and the management of intraoperative blood loss are common threats in thoracic surgical practice. The availability of new procedures, technology and materials is constantly evolving topical hemostats and surgical sealants must be added to this toolkit. Topical hemostats and surgical sealants differ according to their chemical nature and physical characteristics, to their origin and mechanism of action, regulatory/registration and vigilance paths. A Delphi consensus was set to highlight the different points of view on the use of topical haemostatic products and sealants among the members of Italian Society of thoracic surgery., Methods: The board was formed by a group of five Italian experts; in the first phase after a careful review of the scientific literature and two rounds, the board finally generated 16 consensus statements for testing across a wider audience. During the second phase, the statements were collated into a questionnaire, which was electronically sent to a panel of 46 Italian surgeons, experts in the field., Results: Out of 46 Italian surgeons, 33 (72%) panel members responded to the Delphi questionnaire. All the items reached a positive consensus, with elevated levels of agreement, as demonstrated by the presence of a 100% consensus for nine items. For the remaining 7 statements the minimum level of consent was 88% (29 participants approved the statement and 4 disagreed) and the maximum was 97% (32 participants approved the statement and 1 was in disagreement)., Conclusions: The present Delphi analysis shows that air leak and intraoperative bleeding are clinical problems well known among thoracic surgeons. Nevertheless, the aim of the scientific societies and of the group of experts is to execute the education activities in the surgery community. This Delphi survey suggest the need of wider and updated scientific information about technical and registration characteristics of most recent technologic solutions, such as the of topical hemostats and surgical sealants to provide healthcare and administrative staff with the opportunity to work and interact through a common and shared language and eventually to guarantee minimal requirements of assistance., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-22-619/coif).

Background: According to the international guidelines, patients affected by interstitial lung disease with unusual clinical presentation and radiological findings that are not classic for usual interstitial pneumonia end up meeting criteria for surgical lung biopsy, preferably performed with video-assisted thoracic surgery. The growing appeal of non-intubated thoracic surgery has shown the benefits in several different procedures, but the strict selection criteria of candidates are often considered a limitation to this approach. Although several authors define obesity as a contraindication for non-intubated thoracoscopic surgery, the assessment of obesity as a dominant risk factor represents a topic of debate when minor tubeless procedures such as lung biopsy are considered. Our study aims to investigate the impact of obesity on morbidity and mortality in non-intubated lung biopsy patients with interstitial lung disease, analyzing the efficacy and safeness of this procedure., Materials and Methods: The study group of 40 obese patients consecutively collected from 202 patients who underwent non-intubated lung biopsy was compared with overweight and normal-weight patients, according to their body mass index. Post-operative complications were identified as the primary endpoint. The other outcomes explored were the early 30-day mortality rate and intraoperative complications, length of surgery, post-operative hospitalization, patient's pain feedback, and diagnostic yield., Results: The overall median age of the patients was 67.4 years (60, 73.5). No 30-day mortality or significant differences in terms of post-operative complications ( P = 0.93) were noted between the groups. The length of the surgery was moderately longer in the group of obese patients ( P = 0.02). The post-operative pain rating scale was comparable among the three groups ( P = 0.45), as well as the post-operative length of stay ( P = 0.96). The diagnosis was achieved in 99% of patients without significant difference between groups ( P = 0.38)., Conclusion: Our analysis showed the safety and efficacy of surgical lung biopsy with a non-intubated approach in patients affected by lung interstitiopathy. In the context of perioperative risk stratification, obesity would not seem to affect the morbidity compared to normal-weight and overweight patients undergoing this kind of diagnostic surgical procedure., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Cherchi, Ferrari, Guerrera, Grimaldi, Pinna-Susnik, Murenu, Rosboch, Lybéris, Ibba, Balsamo, Saderi, Fois, Ruffini and Sotgiu.)

Background: Surgical lung biopsy for interstitial lung disease (ILD) is traditionally performed through video-assisted thoracic surgery (VATS) and general anesthesia (GA). The mortality and morbidity rates associated with this procedure are not negligible, especially in patients with significant risk factors and respiratory impairment. Based on these considerations, our center evaluated a safe non-intubated VATS approach for lung biopsy performed in ILD subjects., Methods: Ninety-nine patients affected by undetermined ILD were enrolled in a retrospective cohort study. In all instances, lung biopsies were performed using a non-intubated VATS technique, in spontaneously breathing patients, with or without intercostal nerve blockage. The primary end-point was the diagnostic yield, while surgical and global operating room times, post-operative length of stay (pLOS), numeric pain rating scale (NPRS) after surgery and early mortality were considered as secondary outcomes., Results: All the procedures were carried out without conversion to GA. The pathological diagnosis was achieved in 97 patients with a diagnostic yield of 98%. The mean operating room length-of-stay and operating time were 73.7 and 42.5 min, respectively. Mean pLOS was 1.3 days with a low readmissions rate (3%). No mortality in the first 30 days due to acute exacerbation of ILD occurred. Both analgesia methods resulted in optimal feasibility with a mean NPRS score of 1.13., Conclusions: In undetermined ILD patients, surgical lung biopsy with a non-intubated VATS approach and spontaneous ventilation anesthesia appears to be both a practical and safe technique with an excellent diagnostic yield and high level of patient satisfaction., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/jtd-20-1551).
