Abstract
Bullous lung diseases may cause primary spontaneous pneumothorax (PSP) in children. The microRNAs (miRNAs) are non-coding RNAs that participate in regulation of inflammation and cancer. We hypothesized that children with bullous lung disease and PSP may have altered miRNA expressions in their exhaled breath condensates (EBCs). Therefore, a prospective study was performed to evaluate the miRNA-24 and 21 expression, and the matrix metalloproteinase-7 (MMP-7) levels in EBC of children with PSP. Children with PSP were evaluated for age, gender, clinical features and results of surgical treatment. EBC samples (500-1000 ml) were collected to evaluate the miRNA-21, 24 expressions, and MMP-7, and tissue-inhibitor-MMP-1 (TIMP-1) levels. miRNA expressions and MMP levels of patients were compared with healthy controls (control group (CG),n= 12). Subjects (n= 16) with a mean age of 15 years (10-19 years), and a male-to-female ratio of 14:2 were enrolled in this study. The most common presenting symptom was sudden chest pain (n= 14). In 62.5% of the cases an underlying bullous lung disease were detected. During an average of 16.6 months (1-60 months) follow up period, four subjects relapsed. The mean MMP-7 (1.74-1.57 ng ml-1), and TIMP-1 (1.92-1.84 ng ml-1) levels were similar between both groups (p> 0.05). miRNA-24 expression was significantly decreased in the PSP group, when compared to the CG (0.16-1 2-ΔΔCT,p< 0.05). In addition, the miRNA-21 expression was not different between the two groups (p> 0.05). In conclusion, the miRNA-24 levels were significantly decreased in children with PSP. Taken together, children with PSP, especially those with bullous disease, should be closely monitored in the long-term period.

Abstract
This study investigated the correlation between spontaneous pneumothorax (SP) and meteorological factors during different seasons. Patients who visited emergency rooms (ERs) in large cities in Korea and were discharged with SP from 2014 to 2016 were included in this study. Data on temperature, air pressure, and wind speed for each region were collected to obtain each factor's daily maximum, minimum, average, and changes. Days with more than 1 case of SP per million were referred to as pneumothorax days (PD) and those with less than 1 case of SP per million were referred to as non-pneumothorax days (NPD). The environmental factors were assessed on the same day (Day 0), 1 day prior (Day-1), and 2 days prior (Day-2) to PD and NPD per season. A total of 17,846 patients were included in this study. During winter, 4080 patients with SP visited the ERs of large cities with low population densities. The maximum temperature (0.16°C vs 0.76°C, 0.04°C vs 0.87°C, and 0.09°C vs 0.91°C), change in temperature (0.24°C vs 0.90°C, 0.38°C vs 0.81°C, and 0.41°C vs 0.83°C), average atmospheric pressure (0.16 vs 0.52 hPa, 0.25 vs 0.42 hPa, 0.34 vs 0.40 hPa), and maximum atmospheric pressure (0.15 vs 0.53 hPa, 0.28 vs 0.49 hPa, 0.33 vs 0.71 hPa) were greater for Day 0, Day-1, and Day-2, respectively, in PD than in NPD. Meanwhile, the average (0.31 vs 0.48 m/s, 0.28 vs 0.46 m/s, 0.20 vs 0.40 m/s), minimum (0.20 vs 0.31 m/s, 0.18 vs 0.25 m/s, 0.16 vs 0.25 m/s), and maximum (0.44 vs 0.67 m/s, 0.36 vs 0.71 m/s, 0.26 vs 0.58 m/s) wind speeds were slower, and the changes in wind speed (0.44 vs 0.67 m/s, 0.36 vs 0.71 m/s, 0.16 vs 0.25 m/s) were lower for all 3 days in PD than in NPD. High average and change in temperature, slow and unchanging wind speed, and high average and maximum atmospheric pressure were associated with SP. Since many findings of this study were contradictory to previous studies, it is assumed that the interaction of various factors affects SP.

Natural History of Contralateral Bullae/Blebs After Ipsilateral Video-Assisted Thoracoscopic Surgery for Primary Spontaneous Pneumothorax: A Retrospective Cohort Study. Chest 2022; 162:1213-1222. [PMID: 35562058 DOI: 10.1016/j.chest.2022.05.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 05/02/2022] [Accepted: 05/02/2022] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Contralateral bullae/blebs are frequently found in patients who are scheduled to undergo ipsilateral video-assisted thoracoscopic surgery (VATS) for primary spontaneous pneumothorax (PSP). RESEARCH QUESTION Should visible contralateral bullae/blebs be simultaneously resected when ipsilateral VATS bullectomy is performed? STUDY DESIGN AND METHODS In this single-center, retrospective cohort study, we included patients aged ≤ 30 years who underwent ipsilateral VATS for PSP from April 2009 to December 2019. Electronic medical records, radiograph images, and preoperative high-resolution CT images were reviewed. The primary end point was recurrence-free survival (no contralateral pneumothorax) after discharge of ipsilateral VATS for PSP, determined via Kaplan-Meier analysis. Recurrence was compared between the group with and that without contralateral bullae/blebs by using the log-rank test. A multivariable Cox proportional hazards model was constructed to investigate risk factors for contralateral pneumothorax. RESULTS Among 567 patients, contralateral pneumothorax occurred in 86 of them after ipsilateral VATS (15.2%) during a median follow-up period of 51.3 (interquartile range, 67.2) months. The 1-, 5-, and 10-year recurrence-free survival rates were 92.2%, 83.7%, and 79.9%, respectively. Contralateral recurrence was higher in the group with (82/455, 18.0%) than in that without (4/112, 3.6%) contralateral bullae/blebs (P < .001). Age (hazard ratio [HR], 0.701; 95% CI, 0.629-0.780; P < .001), current smoking (HR, 2.106; 95% CI, 1.158-3.831; P = .015), and the presence of bullae/blebs (increasing with size, HR, 4.818-8.980; all P < .05) were independent risk factors for contralateral pneumothorax. The annual rates of contralateral pneumothorax in the group with (4.0%) and in that without (0.7%) contralateral bullae/blebs declined over time. INTERPRETATION Although contralateral bullae/blebs were common in patients who underwent ipsilateral VATS for PSP and were statistically significantly associated with future pneumothorax, the annual rate of pneumothorax was 4.0% in such patients, and it decreased over time. Therefore, a conservative approach on unruptured contralateral bullae/blebs is recommended.

Abstract
Kawasaki disease after respiratory viral infections is often observed but following Human Metapneumovirus infection (HMPV) is uncommon. Pulmonary presentation of Kawasaki disease without its classical features, though uncommon, can present as bronchopneumonia refractory to routine supportive care and antibiotics treatment. Lung collapse and pneumothorax as a pulmonary presentation of atypical Kawasaki disease are described very infrequently. We report an infant with atypical Kawasaki disease secondary to Human Metapneumovirus infection where the above pulmonary complications were observed.

Abstract
Objectives: To identify specific characteristics, distribution and associated findings of lesions causing secondary spontaneous pneumothorax (SSP) Methods: Computed tomography (CT) chest of 37 patients (between October 2011 and January 2020) was evaluated by two radiologists. They were classified into ‘Infectious’ and ‘Non-infectious’ groups, based on cause of pneumothorax. A scoring system (score 0–10) was proposed based on parameters which were statistically significant Results: Out of 37 patients with pneumothorax, 18 could be attributed to infectious aetiology and remaining 19 were due to noninfectious causes. The most common infectious cause of spontaneous pneumothorax was tuberculosis and noninfectious cause was chronic obstructive airway disease (COAD). Statistically significant difference was found for lesion wall thickness and presence of solid component between these two groups. No significant difference was found between both groups when comparing age, gender, lesion size and lesion distribution. The presence of pleural thickening, consolidation and mediastinal lymphadenopathy were statistically significant. Pleural effusion was never present in the noninfectious group. The area under receiver operating characteristic for differentiating patients in the two groups was 0.931 (standard error, 0.038; 95% CI, 0.856–1.000), and optimal threshold score for identifying patients with infectious causes was 4.5, with 77.8% sensitivity and 89.5% specificity Conclusion: Pneumothorax is almost equally common due to infectious and noninfectious causes. The most common infectious cause of spontaneous pneumothorax was tuberculosis and noninfectious cause was COAD. Based on certain CT findings, we have proposed a scoring system to differentiate between these two groups.

Abstract
Pleural space diseases such as recurrent pleural effusion and pneumothorax inflict a significant symptomatic burden on patients. Guidelines and studies are available to guide best practices in the setting of refractory effusions, mostly in the setting of malignancy, and recurrent pneumothorax. Less data is available to guide management of refractory transudative effusions. Recurrent pleural effusions can be treated with tunneled pleural catheters or catheter-based pleurodesis. While refractory transudative effusions can benefit from tunneled pleural catheter, this is an area of ongoing research. Regarding recurrent pneumothorax, video-assisted thoracoscopic surgery (VATS) pleurodesis using mechanical or laser/argon beam coagulation is the most effective means of preventing recurrence. Catheter based pleurodesis, a less invasive means of administering chemical sclerosant via percutaneous thoracostomy tube, is only used when surgery is not an option. However, both approaches induce inflammation of the pleural space, resulting in adherence of the parietal and visceral pleura to prevent fluid or air re-accumulation. This article will discuss catheter based chemical pleurodesis geared toward the interventional radiologist, including a review of disease processes and indications, technique, and strategies to mitigate complications as well as a literature review comparing percutaneous chemical pleurodesis to other therapies.

Abstract
Various complications of hyperemesis gravidarum and pneumomediastinum have been documented in the literature. Commonly, these cases resolve spontaneously or with the use of antiemetics and supportive care. In rare instances, these symptoms persist into the second trimester and are associated with an increased risk of complications. Herein, we present a case of a healthy 20-year-old female with a history of marijuana use who presented with intractable nausea and vomiting and was found to have multiple rare complications of spontaneous pneumomediastinum.

Abstract
Pulmonary Langerhans cell histiocytosis is a rare disease caused by the proliferation of CD1a-positive histiocyte-like cells infiltrating the lung's interstitial layer. Most cases affect young to middle-aged persons, especially adult heavy cigarette smokers. A 49-year-old male heavy smoker (40 pack-year), with non-productive cough, dyspnoea and desaturation, presented with a right-sided pneumothorax on chest x-ray with total atelectasis. Chest computed tomography (CT) revealed bilateral multiple thick-walled infiltrated cysts and multiple ground-glass nodules throughout the entire lung. Surgery with minimal invasive thoracoscopic lung biopsy and pleurodesis was performed. Pathology showed histiocyte-like cells aggregates in the pulmonary parenchyma. Immunohistochemical stain demonstrated CD1a(+), S100(+) and CD68(+). After 3 months of smoking cessation, clear improvement was evidenced with a chest CT showing bilateral multiple thin-walled rounded cysts and multiple ground-glass nodules that are smaller in size and decreased in numbers. Early minimal invasive thoracoscopic lung biopsy and pleurodesis can also be a choice if the development of secondary spontaneous pneumothorax occurs.

Abstract
BACKGROUND During coronavirus pandemic, despite the increase in the number of studies on spontaneous pneumothorax (SP), there is not enough bibliometric study in the literature. In this study, it was aimed to analyze scientific articles published on SP. METHODS Studies published on SP between 1980 and 2021 were obtained from the Web of Science database and analyzed using statistical and bibliometric methods. Spearman correlation coefficient was used for correlation studies. The exponential smoothing estimator was used to forecast publication trend for coming years. Network visualization maps were used to analyze citations and identify trending topics. RESULTS A total of 2422 publications were found. 1403 (57.9%) of these publications were articles. The articles on SP have increased with a non-linear trend in recent years. The top 5 contributors to the literature were USA (231, 16.4%), Japan (161, 11.4%), United Kingdom (98, 6.9%), France (81, 5.7%), and Taiwan (78, 5.5%). The top 3 most active institutions were National Taiwan University Hospital (22, 1.5%), Catholic University Korea (19, 1.3%), and National Taiwan University (19, 1.3%). The top 3 journals that published the most articles were Chest (51), Annals of Thoracic Surgery (46), and Journal of Thoracic Disease (45). The most studied subjects were primary SP, recurrence, thoracoscopy, pleurodesis, video-assisted thoracoscopic surgery, COVID-19, video-assisted thoracic surgery, chest tube(s), and secondary spontaneous pneumothorax. According to trend topics analysis, the keywords studied in recent years are COVID-19, chest tubes, pneumonia, subcutaneous emphysema, risk factors, dyspnea, primary SP, FLCN gene, tension pneumothorax, uniportal, postoperative recurrence, secondary spontaneous pneumothorax, chronic obstructive pulmonary disease, and uniportal. CONCLUSION In this comprehensive bibliometric study, we summarized 1403 articles about SP, which has an increasing trend in the number of articles during the COVID-19 pandemic process. This article can be a useful resource for clinicians and scientists through presenting a summary of worldwide studies related to SP, including the ones during COVID-19 pandemic.

Abstract
Background: Since the onset of the COVID-19 pandemic, there have been many reported cases showing the consequences—or the collateral damages—of COVID-19 on patients with non-COVID-related diseases. This study aimed to compare the clinical manifestations and treatment results of non-COVID-related pneumothorax patients before and during the pandemic. Methods: We retrospectively reviewed non-COVID-related pneumothorax patients who visited our hospital before the onset of the pandemic and during the pandemic. The primary outcome was the difference in the amount of pneumothorax between the two periods, and the secondary outcome was the difference in the treatment results between them. Multivariable logistic regression was conducted to find risk factors related to massive pneumothorax. Results: There were 122 and 88 patients in the pre-pandemic and pandemic groups, respectively. There was no significant difference between the two groups with respect to the preoperative demographic variables. However, the median amount of pneumothorax was significantly higher in the pandemic group (pre-pandemic: 34.75% [interquartile range (IQR) 18.30–62.95] vs. pandemic: 53.55% [IQR 33.58–88.80], p < 0.0001) and massive pneumothorax were more frequent in the pandemic group (52.3% vs. 30.3%, p = 0.002). Furthermore, more patients experienced re-expansion pulmonary edema after treatments during the pandemic (p = 0.0366). In multivariable analysis, the pandemic (OR: 2.70 [95% CI 1.49–4.90], p = 0.0011) was related to the occurrence of massive pneumothorax. Conclusion: During the pandemic, patients presented with a larger size of pneumothorax and had more re-expansion pulmonary edema, even in a country that handled the COVID-19 pandemic relatively well.

Abstract
INTRODUCTION There are various reports of air leaks with coronavirus disease 2019 (COVID-19). We undertook a systematic review of all published case reports and series to analyse the types of air leaks in COVID-19 and their outcomes. METHODS The literature search from PubMed, Science Direct, and Google Scholar databases was performed from the start of the pandemic till 31 March 2021. The inclusion criteria were case reports or series on (1) laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, (2) with the individual patient details, and (3) reported diagnosis of one or more air leak syndrome (pneumothorax, subcutaneous emphysema, pneumomediastinum, pneumoperitoneum, pneumopericardium). RESULTS A total of 105 studies with 188 patients were included in the final analysis. The median age was 56.02 (SD 15.53) years, 80% males, 11% had previous respiratory disease, and 8% were smokers. Severe or critical COVID-19 was present in 50.6% of the patients. Pneumothorax (68%) was the most common type of air leak. Most patients (56.7%) required intervention with lower mortality (29.1% vs. 44.1%, p = 0.07) and intercostal drain (95.9%) was the preferred interventional management. More than half of the patients developed air leak on spontaneous breathing. The mortality was significantly higher in patients who developed air leak with positive pressure ventilation (49%, p < 0.001) and required escalation of respiratory support (39%, p = 0.006). CONCLUSION Air leak in COVID-19 can occur spontaneously without positive pressure ventilation, higher transpulmonary pressures, and other risk factors like previous respiratory disease or smoking. The mortality is significantly higher if associated with positive pressure ventilation and escalation of respiratory support.

Abstract
We report a 33-year-old man who presented with recurrent right pneumothorax. Computed tomography (CT) showed the presence of a large bulla with a maximum diameter of 8 cm in the right middle lobe; he subsequently underwent bullectomy. Histopathology revealed that pulmonary parenchyma adjacent to the bulla represented nodular proliferation of clear cells characterized by a papillary structure resembling placental chorionic villi. Immunohistochemically, clear cells were positive for CD10, suggesting placental transmogrification of the lung (PTL). We reviewed 36 surgical cases of PTL, and only 2 cases (5.6%), including our case, were operated for spontaneous pneumothorax. Bullous lesions secondary to PTL tend to appear as unilateral large cystic masses in non-upper lobes, which is atypical for primary spontaneous pneumothorax (PSP). Although PTL is considered a very rare cause of secondary pneumothorax, we must carefully differentiate this condition.

Abstract
Chiropractic is a very popular alternative medicine practice in the United States. Despite that, this practice has been associated with several complications raising concerns for its safety. We report the case of an otherwise healthy 36-years-old, tall and thin male who presented with sudden onset shortness of breath associated with chest pain two days after chiropractic spinal manipulation. Chest imaging revealed left-sided hemopneumothorax required treatment with left-sided chest tube placement. Patients with a high risk of developing primary or secondary pneumothorax should consider avoiding chiropractic chest or spinal manipulations due to possible complications.

Abstract
Background While the optimal treatment for primary spontaneous pneumothorax remains unclear, mechanical pleurodesis is a well-established treatment. The Pleurabrade is a spiral brush designed for mechanical pleurodesis during thoracoscopy. We present two patients who underwent mechanical pleurodesis with the Pleurabrade. Case Description Two patients with spontaneous pneumothorax underwent operative intervention including mechanical pleurodesis with the Pleurabrade. Chest tubes were removed within 48 hours postoperatively and they were discharged home. Both patients remain recurrence free at 11 and 22 months, respectively. Conclusion While further testing is needed, these case reports and operative video highlight the Pleurabrade as an efficient device for thoracoscopic mechanical pleurodesis.

Abstract
INTRODUCTION Cigarette smoking is associated with primary spontaneous pneumothorax (PSP). Electronic cigarettes (E-cigarettes) are touted as a healthier alternative to cigarettes; however, the impact E-cigarette use has on PSP management is not known. The goal of this study was to determine if E-cigarette use is associated with inferior outcomes after PSP, compared to never smokers and cigarette smokers. METHODS We conducted a retrospective cohort study of patients in a large tertiary care hospital system in an urban area who presented with PSP from September 2015 through February 2019. Primary spontaneous pneumothorax patients were identified from the institutional Society of Thoracic Surgeon (STS) database. Patients with pneumothoraces from traumatic, iatrogenic, and secondary etiologies were excluded. Baseline clinical and demographic data and outcomes including intervention(s) required, length of stay, and recurrence were evaluated. RESULTS Identified were 71 patients with PSP. Seventeen (24%) had unverifiable smoking history. Of the remaining, 7 (13%) currently vaped, 27(50%) currently smoked cigarettes, and 20(37%) were never smokers. Mean age was 33 years; 80% male. All vapers required tube thoracostomy vs 74% of current smokers and 75% of never smokers. Vaping was associated with increased odds of recurrence compared to never smokers (OR 2.00, 95% CI 0.35,11.44). Vapers had the shortest median time to recurrence after initial hospitalization (10 d[4,18] v 20 d[5,13] cigarette smokers v 27 d[13 275] never smokers, P < .001). CONCLUSION Vaping may complicate PSP outcomes. As vaping use increases, especially among adolescents, it is imperative that the manner of tobacco use is documented and considered when caring for patients, especially those with pulmonary problems.

Abstract
Spontaneous pneumomediastinum (SPM) and pneumothorax (PTX) have been described as rare complications of COVID-19 pneumonia. We present a case of COVID-19 pneumonia which was complicated by SPM on Day 13 of admission with progression to spontaneous PTX 2 days later which necessitated intercostal chest drainage. It was complicated by prolonged air leak (PAL) for the next 9 days despite being on continued low-dose suction and another additional larger bore intercostal drain inserted. Surgical pleurodesis was not an option in view of anaesthesia and operative risk expected in COVID-19. In view of this, autologous blood pleurodesis (ABP) to address the alveolar pleural leak was opted. ABP has been previously used for PAL in cases of non-COVID-19-related intractable spontaneous PTX. The air leak ceased with subsequent lung re-expansion, with good clinical and radiological improvement. He was discharged well after resolution of PTX which required intercostal drain for a total of 15 days.

The role of telomerase in the etiology of primary spontaneous pneumothorax. TURK GOGUS KALP DAMAR CERRAHISI DERGISI-TURKISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2021; 29:377-383.

Abstract
Background
This study aims to investigate the role of telomerase activity in the risk of primary spontaneous pneumothorax, which is most frequently encountered in the practice of thoracic surgery.
Methods
A total of 61 patients (56 males, 5 females; median age: 29.4 years; range, 17 to 43 years) who underwent treatment for primary spontaneous pneumothorax and 19 age- and sex-matched healthy controls (10 males, 9 females; median age: 29.1 years; range, 23 to 43 years) were included in this prospective study between January 2018 - August 2018. Telomerase activity was evaluated with enzyme-linked immunosorbent assay. The correlation between telomerase activity and clinical and demographic parameters was examined.
Results
The mean serum telomerase level was 3.4±0.6 ng/mL in the primary spontaneous pneumothorax group and 1.9±0.5 ng/mL in the control group, indicating significantly higher levels in the patient group (p<0.001). There was no significant association between the telomerase levels and presence of blebs and/or bullae on thoracic computed tomography, extent of pneumothorax, laterality (right, left, or bilateral), and pack years of cigarette smoking.
Conclusion
Telomerase levels of patients with primary spontaneous pneumothorax are significantly higher than healthy individuals. Future genetic studies may ultimately clarify a potential relationship between primary spontaneous pneumothorax and short telomere syndrome.

Abstract
Large primary spontaneous pneumothorax (PSP) has traditionally been managed with needle aspiration, chest tube drainage and, in refractory cases, thoracic surgery. A recent randomized trial, however, provided evidence that a conservative observational approach was safe and 85% of patients recovered without requiring pleural drainage interventions. A conservative approach provided similar re-expansion rates at 8 weeks compared with chest tube drainage and offered the advantages of early hospital discharge, fewer days off work and avoidance of procedural risks. Nonetheless, clinicians are understandably anxious with conservative (non-drainage) management for patients with very large pneumothorax. Here, we report a patient with a right-sided PSP and total lung collapse that was managed successfully without intervention with minimal time in hospital or off work.

Abstract
Video-assisted thoracic surgery (VATS) is the treatment of choice for recurrence prevention in patients with spontaneous pneumothorax (SP). Although the optimal surgical technique is uncertain, bullous resection using staplers in combination with mechanical pleurodesis, chemical pleurodesis and/or staple line coverage is usually undertaken. Currently, patient satisfaction, postoperative pain and other perioperative parameters have significantly improved with advancements in thoracoscopic technology, which include uniportal, needlescopic and nonintubated VATS variants. Ipsilateral recurrences after VATS occur in less than 5% of patients, in which case a redo-VATS is a feasible therapeutical option. Randomized controlled trials are urgently needed to shed light on the best definitive management of SP.

Abstract
Introduction: Simultaneous subcutaneous emphysema, spontaneous pneumothorax, and pneumomediastinum are complications rarely observed synchronously during an acute exacerbation of bronchial asthma. Although spontaneous pneumothorax has already been reported in asthma patients in the literature, its concurrence with subcutaneous emphysema and pneumomediastinum is extremely rare except for iatrogenic conditions. Case Study: We describe a patient who presented to the emergency room with progressive dyspnea and chest pain. Three days before, she consulted her general physician with a history of violent dry cough and wheezing. An acute asthma exacerbation was diagnosed, and an inhaled short-acting beta 2 agonist and oral prednisone were prescribed. The patient developed simultaneous subcutaneous emphysema, spontaneous pneumothorax, and pneumomediastinum, a rare complication of an asthma attack. Conclusions: Our aim is to emphasize that occult pneumothoraces should be considered in a patient presenting with an acute asthma attack failing to respond to conventional medical therapy.

Abstract
Spontaneous pneumothorax, which may have an acute or insidious onset in dogs and cats, results in respiratory difficulty and has the potential to be life threatening.1-3 Dogs commonly develop spontaneous pneumothorax due to bullae or blebs, while cats typically have underlying inflammatory disease, like feline allergic airway disease. Urgent therapeutic intervention is essential in animals with respiratory distress. The recommended therapeutic strategies are typically different in each of these species due to underlying etiology. The first part of this review article will focus on physiology, clinical presentation, and diagnosis of spontaneous pneumothorax in dogs and cats. Advances in diagnostics, especially the recent utility of point of care ultrasound, will be discussed. The second part of the series will provide an overview of therapeutic options and management of patients with spontaneous pneumothorax, as well as information on prognosis.

Abstract
Sudden unexpected death due to pneumothoraces caused by spontaneous rupture of bilateral pulmonary bullae is rare. This article reports the case of a 16-year-old girl who experienced this rare phenomenon without any precipitating factors. The patient did not have a history of chest pains or smoking but experienced chest tightness in the early morning and collapsed and died 4 h later. Autopsy identified the cause of death to be bilateral pneumothoraces and massive bilateral pulmonary collapse (atelectasis) due to ruptured apical bullae of the bilateral lungs. No injuries or other significant pathological findings were identified. A low body mass index (16.5) may have been a risk factor for the spontaneous tension pneumothoraces. In some situations, genetic counseling and testing may be helpful in identifying a heritable process associated with spontaneous pneumothoraces.

Abstract
Coronavirus disease 2019 (COVID-19) is an infectious disease primarily affecting the lungs with a spectrum of post-viral complications. There are well-described examples of pneumonia, empyema, pneumomediastinum, and spontaneous pneumothorax cases following COVID-19 infection within the literature. However, there is insufficient evidence implicating the cause of spontaneous pneumothorax in COVID-19 recovered patients. We present a previously infected COVID-19 patient who developed a secondary spontaneous pneumothorax two weeks after recovering. A review of the literature for similar cases was limited and therefore includes a summary of recommendations. Overall, the literature establishes that pneumothorax can occur during different phases of COVID-19 in patients without a history of pulmonary disease or barotrauma and is not necessarily associated with the severity of the viral infection. As in the case of our patient, the culmination of chronic inflammatory changes and an acute exacerbation from COVID-19 further predisposed him to a secondary spontaneous pneumothorax. In summary, all cases of recovered COVID-19 patients should maintain close follow-up with their physician and seek medical attention if acute respiratory symptoms develop.
