Treatment and Outcomes of 844 Cases of Pneumothorax in Heritable Connective Tissue Disorders. Ann Thorac Surg 2024:S0003-4975(24)00466-1. [PMID: 38878950 DOI: 10.1016/j.athoracsur.2024.05.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 05/11/2024] [Accepted: 05/28/2024] [Indexed: 07/04/2024]
Abstract
BACKGROUND Characteristics, practice patterns, and clinical outcomes of secondary spontaneous pneumothorax (SSP) with heritable connective tissue disorders (Marfan, Ehlers-Danlos, and Birt-Hogg-Dubé syndromes) are unclear. METHODS A nationwide Japanese inpatient database that included data of 524 patients with SSP (884 hospitalizations) and 137,821 with primary spontaneous pneumothorax between July 2010 and March 2020 was used in this study. Hospitalization for SSP (n = 884) was categorized into surgical (n = 459) and nonsurgical (n = 425) groups, and the patient characteristics, treatment, and outcomes were compared between the groups. Multivariable analyses were performed to evaluate risk factors for pneumothorax recurrence. We also compared the characteristics of patients with different underlying heritable connective tissue disorders. RESULTS Compared with the nonsurgical group, the surgical group had less frequent readmission for pneumothorax (26% vs 44%; hazard ratio, 0.47; 95% CI, 0.38-0.58). Young patients (2.46; 1.83-3.32) or those with Birt-Hogg-Dubé syndrome (2.53; 1.77-3.63) had a high risk of recurrence. Pneumothorax occurred frequently in teenagers with Marfan syndrome, in those aged 20 to 39 years with Ehlers-Danlos syndrome, and in those aged ≥40 years with Birt-Hogg-Dubé syndrome. CONCLUSIONS Detailed information on the characteristics and clinical course of SSP in heritable connective tissue disorders will aid in the clinical decision-making process.

Management of primary spontaneous pneumothorax in children: A single institution protocol analysis. J Pediatr Surg 2023:S0022-3468(23)00075-1. [PMID: 36803908 DOI: 10.1016/j.jpedsurg.2022.12.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 12/13/2022] [Accepted: 12/31/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND The Midwest Pediatric Surgery Consortium (MWPSC) suggested a simple aspiration of primary spontaneous pneumothorax (PSP) protocol, failing which, Video-Assisted Thoracoscopic Surgery (VATS) should be considered. We describe our outcomes using this suggested protocol. METHODS A single institution retrospective analysis was conducted on patients between 12 and 18 years who were diagnosed with PSP from 2016 to 2021. Initial management involved aspiration alone with a ≤12 F percutaneous thoracostomy tube followed by clamping of the tube and chest radiograph at 6 h. Success was defined as ≤2 cm distance between chest wall and lung at the apex and no air leak when the clamp was released. VATS followed if aspiration failed. RESULTS Fifty-nine patients were included. Median age was 16.8 years (IQR 15.9, 17.3). Aspiration was successful in 33% (20), while 66% (39) required VATS. The median LOS with successful aspiration was 20.4 h (IQR 16.8, 34.8), while median LOS after VATS was 3.1 days (IQR 2.6, 4). In comparison, in the MWPSC study, the mean LOS for those managed with a chest tube after failed aspiration was 6.0 days (±5.5). Recurrence after successful aspiration was 45% (n = 9), while recurrence after VATS was 25% (n = 10). Median time to recurrence after successful aspiration was sooner than that of the VATS group [16.6 days (IQR 5.4, 19.2) vs. 389.5 days (IQR 94.1, 907.0) p = 0.01]. CONCLUSION Simple aspiration is safe and effective initial management for children with PSP, although most will require VATS. However, early VATS reduces length of stay and morbidity. LEVEL OF EVIDENCE IV. Retrospective study.

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
Air in the pleural cavity is termed pneumothorax. When this occurs in the absence of trauma or medical intervention, it is called spontaneous pneumothorax. Primary spontaneous pneumothorax typically occurs in young patients without known lung disease. However, the idea that these patients have “normal” lungs is outdated. This article will review evidence of inflammation and respiratory bronchiolitis on surgical specimens, discuss the identification of emphysema-like change (i.e., blebs and bullae), the concept of pleural porosity and review recent data on the overexpression of matrix metalloproteinases in the lungs of patients who have had pneumothorax.

Abstract
INTRODUCTION The management of primary spontaneous pneumothorax (PSP) in pediatrics remains controversial. The aim of this study was to investigate the risk of recurrence after non-surgical treatment vs. surgery, the difference in the length of stay (LOS) between various treatment options, and the role of computed tomography (CT) in the management of PSP. MATERIALS AND METHODS We retrospectively reviewed patients admitted to our Pediatric Surgery Unit for an episode of PSP between June 2009 and July 2020. Medical records including clinical presentation at admission, diagnostics, treatments, complications, and LOS were collected. RESULTS Twenty-three patients (22 males and 1 female) were included in this study. Median age was 15.65 (range 9-18). Chest X-rays were performed in all patients and showed 5 small (22%) and 18 large (78%) PSP. Chest drain was used for large PSP (≥2 cm) if the patient was clinically unstable. Eleven patients (48%) were managed non-operatively with observation alone and a recurrence rate of 18%, chest drain was used in 11 patients with a recurrence rate of 36%, and surgery was deemed necessary as a first treatment choice in one case. Six patients (27%) had an episode of relapse after non-operative management or chest drain placement. Following surgery, a relapse occurred in 2 of the 6 patients. Chest drain insertion was associated with a longer LOS than observation alone (6.36 vs. 2.4 days), and surgery resulted in a longer LOS than other types of treatment (P = 0.001). CONCLUSION According to our experience, small PSP or clinically stable larger PSP can be treated conservatively with observation alone. Operative management should be taken into consideration in children with large symptomatic PSP, persistent air leak, and/or relapse after chest drain insertion.

Abstract
BACKGROUND In adults with primary spontaneous pneumothorax (PSP), contralateral recurrence occurs in about 25-28% when there are asymptomatic blebs. How to treat contralateral recurrence of PSP in pediatric populations remains controversial. This study evaluated the outcomes of excising contralateral blebs to prevent recurrence in adolescents being operated on for PSP under the same anesthesia. METHODS One hundred thirty-two male PSP patients under age 19 were surgically treated in a single institution between January 2008 and December 2016. Thoracoscopic blebectomies with pleurodesis were performed in all patients. The patients were categorized into those with contralateral blebs receiving one-stage bilateral surgeries (32 patients), those with contralateral blebs only receiving unilateral surgeries (40 patients), and those without contralateral blebs only receiving unilateral surgeries (60 patients). Perioperative details and outcomes were retrospectively analyzed. RESULTS Significant differences in contralateral recurrence rate were found among the three groups (0%, 30%, and 1%, respectively; P < 0.001). Multivariate analysis showed that being under 16.5 years old was a risk factor for overall recurrence (Hazard ratio [HR] 2.81, 95% confidence interval [CI] 1.08-7.30, P = 0.034). Moreover, patients who had contralateral blebs and only received unilateral surgery were at greater risk of overall recurrence (HR 6.06, 95% CI 1.77-20.75, P = 0.004). Kaplan-Meier analysis showed that contralateral and overall recurrence-free survival differed among the three groups (P < 0.0001, P = 0.0002). CONCLUSIONS Although younger male PSP adolescents treated with surgery were more likely to have postoperative recurrences, the performance of simultaneous contralateral blebectomies in those receiving one-stage bilateral surgeries significantly reduced future contralateral recurrence without compromising patient safety.

Abstract
OBJECTIVES This retrospective cohort study aimed to analyse the impact of asymptomatic blebs/bullae on the occurrence of primary spontaneous pneumothorax (PSP) by monitoring the natural course of contralateral blebs/bullae in patients with ipsilateral pneumothorax. METHODS From January 2003 to December 2017, 1055 patients [age 19.6 ± 3.98 years (mean ± standard deviation), 953 men] experiencing the first episode of unilateral PSP were enrolled in this study, excluding patients aged 30 years or more. The presence, number and maximal size of the blebs/bullae were investigated in contralateral asymptomatic lungs based on high-resolution computed tomography. RESULTS Multiple and single blebs/bullae were noted in contralateral lungs in 425 (40.3%) and 88 (8.3%) patients, respectively. The median follow-up period was 44.0 (interquartile range 71.5) months. The 1-, 3- and 5-year cumulative occurrence rates of PSP in contralateral lungs were 7.9%, 13.7% and 16.7%, respectively. On multivariable analysis, younger age [hazard ratio (HR) 1.19, 95% confidence interval (CI) 1.12-1.27; P < 0.001) and multiple bullae (HR 4.42, 95% CI 3.06-6.38; P < 0.001) were independent risk factors for spontaneous pneumothorax in the contralateral lung. The 5-year cumulative occurrence rates of PSP were significantly higher in patients with multiple blebs/bullae than in those with no or a single bleb/bulla (28.2% vs 8.5%, respectively; P < 0.001). CONCLUSIONS Asymptomatic blebs/bullae often lead to PSP. If the patient is eligible for surgery for pneumothorax, preemptive surgery for contralateral bullae could be considered, especially in patients with multiple blebs/bullae.

Abstract
Background Primary spontaneous pneumothorax (PSP) prevalence is typically higher in juvenile patients than in adults. We aimed to evaluate the optimal treatment for primary spontaneous pneumothorax and its efficacy and safety in juveniles. Materials and methods We searched PubMed, Embase, and Cochrane databases for eligible studies published from database inception to October 10, 2020, and conducted a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary and secondary outcomes were recurrence rate and hospital stay length, respectively. Odds ratios (OR) and mean differences were used for quantitatively analyzing binary and continuous outcomes, respectively. In total, nine retrospective studies with 1,452 juvenile patients (aged <21) were included for the quantitative analysis. The surgical approach led to a lower recurrence rate than did conservative approaches (OR: 1.95, 95% confidence interval: 1.15–3.32). Moreover, the recurrence rate was low in patients who underwent conservative treatment first and received surgery later. Conclusions Surgical approach for first-line management might have a greater effect on recurrence prevention than do conservative approaches. An upfront surgery might be an optimal choice for juvenile primary spontaneous pneumothorax.

Abstract
BACKGROUND Spontaneous pneumothorax is a common problem globally. Bullas and blebs have been implicated in this problem, but the etiology of their formation is unknown. We aim to show the relation between a novel clinical finding, the pulmonary delayed inflation (PDI) sign, and the etiology of bulla and bleb formation in young patients. METHODS We retrospectively analyzed data from 111 patients with pneumothorax and a control group of 27 patients. We evaluated the relation between the PDI sign and other clinical factors. RESULTS The PDI sign was observed in 78 patients. Of these, 75 exhibited the PDI sign in only the upper lobe. Regardless of smoking status, patients 34 years of age or younger had a significantly higher incidence of the PDI sign than, patients 55 years of age or older and control patients. The inflation time in patients 34 years of age or younger, regardless of smoking status, was significantly longer than in patients 55 years of age or older and patients in the control group. There was no significant association between inflation time and the presence of asthma. CONCLUSIONS The novel PDI sign is seen in patients 34 years of age or younger. Because this sign may indicate a peripheral bronchial abnormality and may be related to the formation of blebs and bullae in young patients with spontaneous pneumothorax, it is possible that it can be used to develop effective treatments for pneumothorax in young patients.

Recurrence rate and risk factors for recurrence after thoracoscopic surgery for primary spontaneous pneumothorax: A nationwide population-based study. J Formos Med Assoc 2020; 120:1890-1896. [PMID: 33384212 DOI: 10.1016/j.jfma.2020.12.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 10/18/2020] [Accepted: 12/08/2020] [Indexed: 11/28/2022] Open
Abstract
PURPOSE This large-scale nationwide population-based study aimed to determine the recurrence rate and risk factors for recurrence after video-assisted thoracoscopic surgery (VATS) for primary spontaneous pneumothorax (PSP). METHODS This retrospective study used data from the Taiwan National Health Insurance Database to identify individuals who underwent VATS for PSP from 2007 to 2014. All patients were followed up until December 31, 2017. Study variables included demographic characteristics, intensive care unit admission, lung resection status, use of non-steroidal anti-inflammatory drugs (NSAIDs), and hospital level. The primary outcome was 1-year recurrence, and the secondary outcomes were the 1-year rate of reintervention for recurrence and overall recurrence rate. RESULTS During the study period, 6654 patients underwent VATS for PSP (average age: 23.2 years, 89.1% male), including 910 patients (13.7%) who experienced recurrence within 1 year and 531 patients (8.0%) who required reintervention within 1 year. The overall recurrence rate was 24.8%, with an average follow-up time of 6.7 years. Age ≤18 years and the use of NSAIDs, especially ketorolac, were significant risk factors for 1-year recurrence and overall recurrence. Younger age was a risk factor for 1-year reintervention. In subgroup analysis, NSAID use was a significant risk factor for 1-year recurrence, 1-year reintervention, and overall recurrence in pediatric patients but not in adult patients. CONCLUSIONS In Taiwan, the 1-year recurrence rate was 13.7% after VATS for PSP. Younger age and the use of NSAIDs, especially ketorolac, were significant risk factors for short- and long-term recurrence after VATS for PSP.

Abstract
Background Patients with Marfan syndrome (MFS) often develop pneumothorax, but the features of pneumothorax in the context of MFS have not been well described in the literature. We clarified the clinical and histopathological characteristics of this condition in these patients. Methods Patients with MFS were selected from among all patients who underwent surgery for pneumothorax, between December 1991 and January 2015, in our hospital. We studied the histopathological characteristics of the resected lungs as well as the clinical features of the selected patients, including surgical findings and postoperative recurrence status. Results There were 966 operations underwent pneumothorax-related surgeries in our hospital. A total of 16 operations (1.66%) were performed on patients with MFS in 11 cases. In this study, 9 patients (6 men, 3 women) were included. Clinically, 7 patients (77.8%) had bilateral pneumothoraces and 4 (44.4%) exhibited postoperative recurrent pneumothoraces. Pathologically, the resected pulmonary bullae exhibited blood vessel cystic medial degeneration (55.6% of cases), calcification (55.6% of cases), and demonstrated elastic fiber fragmentation and degeneration (all cases). Conclusions As in few previous reports, many patients with MFS develop bilateral or postoperative recurrent pneumothoraces. In many patients, characteristic changes in the pulmonary bullae, possibly caused by degenerated elastic fibers, were observed.

Abstract
OBJECTIVE Primary spontaneous pneumothorax is relatively rarer in women than in men. In addition, women develop secondary spontaneous pneumothorax, such as lymphangioleiomyomatosis, which is rare and difficult to diagnose. Therefore, the clinical characteristics of primary spontaneous pneumothorax in women remain unknown presently. We compared the clinical characteristics of primary spontaneous pneumothorax between the two sexes at two pneumothorax centers. METHODS Between January 2015 and July 2019, we retrospectively evaluated 627 cases (106 women and 521 men) who underwent first video-assisted thoracoscopic surgery for primary spontaneous pneumothorax and extracted the medical backgrounds and postoperative recurrence between the sexes. Univariate and multivariate analysis was used to examine the effect of sexual specificity on postoperative recurrence. RESULTS Among women and men with PSP, the mean ages were 27.8 ± 10.7 and 24.3 ± 10.0 years, respectively; their mean heights were 162.0 ± 5.9 and 173.3 ± 6.1 cm, respectively. These differences were statistically significant. Three women (2.8%) and 54 men (10.4%) developed postoperative recurrence, which showed significant difference on Kaplan-Meier analysis (p = 0.027). Univariate and multivariate analysis showed the factors; women (p = 0.045, hazard ratio: 0.289 [95% confidence interval 0.086-0.973]) and smoker (p = 0.035, hazard ratio: 0.269 [95% confidence interval 0.079-0.909]) had the preventing factor for postoperative recurrence, respectively. CONCLUSIONS Women with PSP had lower postoperative recurrence rate than men. Although we could not reveal why women had lower postoperative recurrence rates than men in this study, the sexual difference such as hormonal cycle, development of body structure possibly affects the clinical characteristics of women with primary spontaneous pneumothorax.

Abstract
Primary spontaneous pneumothorax (PSP) is a commonly known condition due to the accumulation of air in the pleural space in otherwise healthy people, without apparent underlying lung disease. To date, the exact pathogenesis of PSP is unclear, but it still represents a public health issue. We performed a review of the literature concerning the epidemiology of PSP, examining age of onset and presentation symptoms, in order to assess the possible correlation between these characteristics and its occurrence. Data concerning age, signs, and symptoms were collected. For description purposes, information regarding aetiological and anthropomorphic data was also gathered. In total, 265 papers were evaluated. Regarding age of onset, PSP is a disease that can occur in a broad age group with a double cluster (15-30 and 40-45 yr). Regarding symptoms, pain and dyspnoea (in its various forms) are the most described in PSP. Pain was recorded in 69.25% (range, 9-100%) of the population studied, whereas dyspnoea was present in an average of 54.55% (range, 27-77.1%). Tobacco exposure seems to play an important role in the early onset of PSP. Concerning age at presentation, this review highlights that PSP can occur over a broad age range. The literature appears to be consistent in reporting PSP occurrence mostly below 45 years of age. Asymptomatic PSP is an almost unseen entity. Finally, of pollutants, cigarette smoking should be considered as the most significant exogenous risk factor in the development of PSP.

Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) is reported to be more common in young men who are thin and tall. This retrospective study aimed to analyze the clinical and chest wall characteristics associated with PSP. MATERIAL AND METHODS Between January 2008 to December 2017, the clinical and imaging data of 99 patients at first presentation with PSP were compared with 82 age-matched healthy controls. Computed tomography (CT) imaging was used to measure the anteroposterior and transverse diameters of the chest at four levels, including the aortic arch, tracheal bifurcation, right inferior pulmonary vein, and lower sternal edge. Chest deformity was calculated as the ratio of the transverse diameter of the hemithorax divided by anteroposterior diameter. Lung volume and average lung density of 32 cases with PSP were measured and compared with 10 patients without PSP. Intrapleural pressure of 43 cases PSP who were treated with a closed chest drain was measured and compared with 39 patients with mediastinal tumor who underwent thoracoscopic surgery. RESULTS Patients with PSP showed a normal age distribution with a median of 17-18 years. The patients with PSP had significantly reduced anteroposterior and transverse diameters of the chest when compared with controls at four levels on CT (p<0.01). The lung volumes in patients with PSP were significantly reduced when compared with the controls (p<0.05), as were the minimum intrapleural pressure and pressure difference (p<0.05). CONCLUSIONS The findings support that chest wall dimensions may be associated with lung development, which are contributing factors in PSP.

Abstract
Background Recurrence of pneumothorax after thoracoscopic surgery is a concerning issue for thoracic surgeons. In this study, we aimed to determine the risk factors for recurrence of spontaneous pneumothorax after thoracoscopic surgery. Methods A total of 192 patients with spontaneous pneumothorax aged <50 years who underwent thoracoscopic surgery from January 2010 to December 2016 were included in this study. Pre- and post-operative characteristics were obtained from medical records, and recurrent and non-recurrent cases were compared. Results Fourteen patients (7.3%) experienced pneumothorax recurrence. Pneumothorax recurrence was observed more frequently in patients aged <20 years (P=0.041) and those in whom bullae were not identified on preoperative computed tomography (CT) (P=0.049). The use of polyglycolic acid (PGA) sheets during surgery significantly decreased the recurrence rate (P=0.031). A history of ipsilateral pneumothorax before surgery was a significant risk factor for recurrence after thoracoscopic surgery (P=0.001). In the multivariate analysis, a history of ipsilateral pneumothorax and identification of bullae on CT were identified as significant risk factors for recurrence. Conclusions A history of ipsilateral pneumothorax, and inability to identify bullae on preoperative CT were risk factors for postoperative recurrence of pneumothorax.

Abstract
OBJECTIVES To review the literature for justification of thoracoscopic management of blebs in children. METHODS PubMed database was reviewed for articles in English, Portuguese and Spanish using the key words "thoracoscopy", "bleb" and "child". Data was collected for age, gender, type of surgery performed, operating time, conversions, complications, recurrences, follow-up and mortality. RESULTS Eleven studies with total 266 patients were included (27 bilateral cases; n = 293 surgeries). Median age was 15.7 y (range 11-18 y), 225 were male (87.9%) and 31 were female (12.1%) patients. Endo GIA™ was used in 10 cases, Endoloop® in 11 surgeries, unspecified stapler devices in 150 procedures and, in 122 surgeries, instruments were not mentioned. Pleurodesis was performed in 213 (72.7%) cases. There were 5 (1.7%) conversions (adhesions n = 3, bleeding n = 1, camera failure n = 1). Complications were documented in 8 (2.7%): pneumothorax after chest tube removal 4 (drain reinsertion n = 3, reoperation n = 1); prolonged air leak 3, all submitted to che pleurodesis; bleeding requiring reoperation 1. Recurrence occurred in 25 (8.5%): 10 re-operation, 7 conservative management, 2 chemical pleurodesis, 2 chest tube reinsertions and in 4 the management was not specified. The median follow-up was 46.1 mo (range 3 mo-11 y). There were no lethal outcomes. CONCLUSIONS Although data is scarce on specific instruments used, pleurodesis is performed in 70% of cases. Irrespective of this, thoracoscopic resection of blebs can be safely offered as it has a low complication and conversion rates and no mortality.

Abstract
OBJECTIVE The purpose of this study was to test the hypothesis that apical opacities on computed tomography (CT) are related to occurrence of primary spontaneous pneumothorax (PSP) in young male patients. METHODS We compared the frequency of apical opacities on thin-section CT between 70 male patients with PSP (PSP group) and 74 male patients without a history of PSP (non-PSP group). We also evaluated histopathologic findings of 39 specimens from 37 surgical cases in the PSP group. RESULTS Apical opacities were significantly more frequent in the PSP group than in the non-PSP group (right side, P = 0.01; left side, P = 0.005). Histopathologically, subpleural band-like alveolar collapse was seen in 35 specimens (89.7%), which was always accompanied by fibroelastosis and fibroblastic foci. CONCLUSIONS Apical opacities on CT were significantly associated with PSP in young male patients. These apical opacities histopathologically correspond to fibrotic pleural thickening with subpleural alveolar collapse.

Abstract
BACKGROUND Preventive surgery for contralateral recurrence of primary spontaneous pneumothorax (PSP) remains controversial and few studies discussed both ipsilateral and contralateral recurrences simultaneously. Thus, we aimed to identify the predictors of ipsilateral and contralateral PSP recurrence and to review literatures on the association of blebs/bullae on HRCT with PSP recurrence. METHODS We retrospectively reviewed consecutive patients who were treated at our hospital for first recurrence of PSP between January 2001 and December 2005. RESULTS This study included 553 patients who were followed-up for a mean period of 124 months. Ipsilateral and contralateral recurrence of PSP developed in 19.35% and 15.19% of patients, respectively. In the Cox regression analysis, the only significant predictors were no video-assisted thoracoscopic surgery (VATS) bullectomy (OR: 16.629, P<0.001) for ipsilateral recurrence, and the presence of blebs/bullae on HRCT (OR: 3.215, P=0.024) and low BMI (<18.5 kg/m2) (OR: 1.560, P=0.045) for contralateral recurrence. CONCLUSIONS VATS bullectomy was a strong independent predictor for prevention of ipsilateral PSP recurrence. Patients with contralateral blebs or bullae on chest HRCT or those with low BMI may be candidates for preventive VATS bullectomy to avoid recurrences and possible complications.

Abstract
BACKGROUND To examine the bone mineral density (BMD) and the role of bone biomarkers, including bone formation marker procollagen type I aminoterminal propeptide (PINP) and N-terminal midmolecule fragment osteocalcin (N-MID), bone resorption marker b-C-telopeptides of type I collagen (b-CTX) and tartrate-resistant acid phosphatase 5b (TRACP5b) in the pathogenesis of PSP. METHODS Eighty-three consecutive primary spontaneous pneumothorax (PSP) patients (PSP group) and 87 healthy individuals (control group) were enrolled in this study. General data, including gender, age, height, weight, and body mass index (BMI), were recorded. Dual-energy X-ray absorptiometry, electrochemiluminescence immunoassay (ECLIA), and ELISA were used to evaluate bone mineral density and expression levels of bone metabolism markers, including PINP, b-CTX, TRACP5b, N-MID, and 25-hydroxyvitamin D (25-OH VD). RESULTS Mean height was significantly greater in the PSP group compared with the control group, whereas weight and BMI were lower. Patients in the PSP group had significantly lower average bone mineral density, which mainly manifested as osteopenia (11/12, 91.7%); however, only one patient (8.3%) developed osteoporosis. Serum overexpression of PINP, b-CTX, TRACP5b, and N-MID were found in PSP patients. Expression of 25-OH VD was low in PSP patients. Bone resorption markers showed positive linear relationships with bone formation markers in all participants; whereas only TRACP5b expression negatively correlated with 25-OH VD. Expression levels of all bone turnover markers negatively correlated with BMI. Regression analysis identified risk factors of PSP as age, height, weight, and TRACP5b and 25-OH VD expression levels; whereas gender and PINP, b-CTX, and N-MID expression levels were not significantly associated with the onset of PSP. CONCLUSIONS It had lower bone mineral density in PSP patients. Bone formation marker PINP, N-MID and bone resorption marker b-CTX, TRACP5b were upregulated in PSP patients. 25-OH VD expression was relatively low in this population of PSP patients. Age, height, weight, and expression levels of TRACP5b and 25-OH VD may be risk factors for PSP.

Abstract
Despite elevated incidence and recurrence rates for Primary Spontaneous Pneumothorax (PSP), little is known about its etiology, and the genetics of idiopathic PSP remains unexplored. To identify genetic variants contributing to sporadic PSP risk, we conducted the first PSP genome-wide association study. Two replicate pools of 92 Portuguese PSP cases and of 129 age- and sex-matched controls were allelotyped in triplicate on the Affymetrix Human SNP Array 6.0 arrays. Markers passing quality control were ranked by relative allele score difference between cases and controls (|RASdiff|), by a novel cluster method and by a combined Z-test. 101 single nucleotide polymorphisms (SNPs) were selected using these three approaches for technical validation by individual genotyping in the discovery dataset. 87 out of 94 successfully tested SNPs were nominally associated in the discovery dataset. Replication of the 87 technically validated SNPs was then carried out in an independent replication dataset of 100 Portuguese cases and 425 controls. The intergenic rs4733649 SNP in chromosome 8 (between LINC00824 and LINC00977) was associated with PSP in the discovery (P = 4.07E-03, ORC[95% CI] = 1.88[1.22–2.89]), replication (P = 1.50E-02, ORC[95% CI] = 1.50[1.08–2.09]) and combined datasets (P = 8.61E-05, ORC[95% CI] = 1.65[1.29–2.13]). This study identified for the first time one genetic risk factor for sporadic PSP, but future studies are warranted to further confirm this finding in other populations and uncover its functional role in PSP pathogenesis.

Abstract
Primary spontaneous pneumothorax recurs at a certain rate after thoracoscopic surgery, and risk factors for that recurrence are in question. The medical records of 248 patients with primary spontaneous pneumothorax who were followed for more than 2 years after thoracoscopic surgery were reviewed and retrospectively analyzed. Univariate and multivariate binary logistic regression analysis were used to identify possible risk factors. Twelve patients experienced the recurrence of primary spontaneous pneumothorax. Patients who experienced the recurrence of primary spontaneous pneumothorax were younger than patients who experienced no recurrence. A larger proportion of the patients who experienced recurrence did not undergo pleurodesis. The variables age, height, weight, body mass index, duration of air leakage, and pleurodesis (performed or not) with a p value less than 0.2 in univariate analysis were entered in multivariate analysis. A younger age and not undergoing pleurodesis were associated with a higher risk of postoperative ipsilateral recurrence of primary spontaneous pneumothorax. Not undergoing pleurodesis and a younger age are possible risk factors for recurrence of primary spontaneous pneumothorax after thoracoscopic surgery. Thoracic surgeons should pay more attention to pleurodesis, especially in younger patients.

Abstract
OBJECTIVES Although better nutritional support has improved the growth rates in children, the occurrence of primary spontaneous pneumothorax has also been increasing in children. The current study attempts to investigate the occurrence and recurrence of primary spontaneous pneumothorax and the efficacy of surgery for primary spontaneous pneumothorax in young adults and children. METHODS A total of 840 patients were treated for pneumothorax at our hospital from January 2006 to December 2010. Exclusion criteria for this study were age >25 or secondary, traumatic or iatrogenic pneumothorax, and a total of 517 patients were included. Patients were classified into three groups according to age at the first episode of primary spontaneous pneumothorax: Group A: ≤16 years; Group B: 17-18 years and Group C: ≥19 years. RESULTS The study group was composed of 470 male and 47 female patients. There were 234 right-sided, 279 left-sided and 4 bilateral primary spontaneous pneumothoraces. Wedge resection by video-assisted thoracic surgery was performed in 285 patients, while 232 were managed by observation or closed thoracostomy. In the wedge resection group, 51 patients experienced recurrence. The recurrence rates after wedge resection were 27.9% in Group A, 16.5% in Group B and 13.2% in Group C (P = 0.038). The recurrence rates after observation or closed thoracostomy were 45.7% in Group A, 51.9% in Group B and 47.7% in Group C (P = 0.764). CONCLUSIONS In the present study, postoperative recurrence rates were higher than those in the literature. Intense and long-term follow-up was probably one reason for the relatively high recurrence rate. The recurrence rate after wedge resection in patients aged ≤16 years was higher than that in older patients. There was no difference between the recurrence rates after observation or closed thoracostomy, regardless of age. These results suggest that wedge resection might be delayed in children.

Abstract
BACKGROUND We determined the chest height in a cohort of patients with primary spontaneous pneumothorax (PSP) who had received chest radiographic examinations prior to the attack. The aim of this study was to determine when their chest height began to change and how this was related to the PSP. METHODS From June 2009 to February 2012, the chest posteroanterior radiographs of 156 patients with PSP (Group 1) were reviewed. Among another 3134 patients with PSP, we identified 52 patients who had a chest posteroanterior radiograph prior to the attack (Group 2). We also recruited 196 controls for comparison (Group 3). The chest height and chest width at different levels were measured and analyzed. RESULTS Before 14 years of age, the chest height of patients in Group 2 was no different from that of patients in Group 3. By the age of 14 years, however, the chest height and upper chest width of patients with PSP was significantly higher than that of the normal controls. The difference from normal chest height did not increase at adulthood. CONCLUSION The rapid increase in chest height and upper chest width is a unique finding in patients with PSP. It might be attributable to the occurrence of PSP. This finding may also help to identify patients who are at risk of PSP.

Abstract
We describe two unrelated patients with molecularly confirmed Sotos syndrome with multiple subpleural blebs and pneumothorax. We propose this as a new association. Patient 1 is a 3-year-old boy with a 1.9 Mb interstitial deletion of the long arm of chromosome 5, with breakpoints at q35.2 and q35.3, encompassing NSD1 and Patient 2 is a 9-year-old girl with a de novo truncating mutation within NSD1. Both patients presented with sudden onset dyspnea due to a unilateral pneumothorax: Patient 1 at the age of 18 months and Patient 2 at 9 years. In both, the pneumothorax recurred following removal of the chest drain and, on further investigations, multiple subpleural blebs were identified necessitating a pleurodesis and tissue resection. This is the first report of multiple subpleural blebs leading to pneumothorax in association with Sotos syndrome. Given the similar and unusual presentation in the two affected patients, we suggest that this may be a real association, albeit a rare one. While screening would not be advocated for such a rare association, we recommend that clinicians consider pneumothorax in patients with Sotos syndrome and sudden onset of dyspnea and are aware that it may be refractory to first line treatment.

Abstract
PURPOSE Recurrence is the most common complication after an initial episode of primary spontaneous pneumothorax (PSP). However, preventive surgery in children remains a controversial issue. The purpose of this study was to determine predictive factors of recurrence to better inform early surgical referrals. METHODS We retrospectively reviewed all consecutive patients under 18 years of age who conservatively treated for an initial episode of PSP between March 2005 and September 2011. RESULTS One hundred fourteen patients were included in this study. The mean follow-up period was 43.1 months. Ipsilateral and contralateral recurrence developed in 47.3% and 14.0% of patients. The risk of ipsilateral recurrence for patients with or without air-containing lesions according to high-resolution computed tomography (HRCT) was 60.3% and 31.4%. In the multivariate analysis, the presence of air-containing lesions on HRCT scans and bullae on chest X-rays were independent risk factors for ipsilateral recurrence. CONCLUSION The presence of bleb or bullae on HRCT scans or chest X-rays after an initial episode of PSP was significantly related to the ipsilateral recurrence in children. If the risk factors are clarified in further studies, hospital stays and the recurrence of PSP after the first episode could be reduced with early video-assisted thoracoscopic surgery.

Abstract
Many diagnostic and therapeutic options exist for the evaluation and treatment of patients with pneumothorax. Guidelines from US and European professional societies and individual expert opinions differ in the approach to patient care. Advances in diagnostic techniques, such as real-time thoracic ultrasound, have added to the evaluation strategy. It is important for medical trainees and providers to become familiar with techniques utilized worldwide as they may be encountered in clinical practice. We review current evidence, expert recommendations, and compare professional society guidelines discussing the various diagnostic and management options for patients with pneumothorax to assist physicians and trainees involved in the care of hospitalized and outpatient adults who have primary, secondary, and traumatic iatrogenic pneumothorax. Management of traumatic non-iatrogenic pneumothorax is beyond the scope of this article, thus, not reviewed here.

Abstract
PURPOSE There is controversy regarding the best way to prevent recurrences of primary spontaneous pneumothorax (PSP) in children. The purpose of this study was to evaluate the efficacy of video-assisted thoracoscopic surgery (VATS) for pediatric PSP. METHODS We retrospectively reviewed patients under 29 years of age who underwent VATS for PSP between March 2005 and February 2011. Patients were divided into 2 groups: children (under the age of 17 years) and young adults (over the age of 18 years). RESULTS Two hundred eighty-one VATS procedures in 257 patients were included in this study. The mean follow-up was 47.1 ± 20.5 months. No mortality was observed. The mean duration of pleural drainage was 3.4 ± 2.2 days. The overall recurrence rate was 6.8 %. The operative outcomes did not differ significantly. However, the recurrence rate was significantly higher in the children's group than the young adult group (10.6 vs. 3.9 %, P = 0.032). Younger age and postoperative prolonged air leak had a significantly higher risk of postoperative recurrence. CONCLUSIONS VATS is a safe and effective procedure for PSP in children. However, the risk of recurrence is increased in children and it is related to the formation of new bullae.

Abstract
PURPOSE To clarify whether fibulins-5 is associated with primary spontaneous pneumothorax (PSP) in young PSP patients. METHODS Forty-six surgically resected, fresh lung specimens were used. Patients were divided into 3 groups: younger than 25 years with pneumothorax (group Y), 25 years or older with pneumothorax (group O), and without pneumothorax (group C). Chest X-ray, computed tomography data, height/width ratio (H/W) and anteroposterior/transverse diameter ratio (a/b) were measured. Elastica van Gieson staining and immunofluorescence staining for fibulin-5 were performed. Fibulin-5 mRNA expression and protein levels were measured by real-time PCR and western blotting. Direct sequences of the fibulin-5 gene in PSP patients were performed. RESULTS The mean H/W ratio in group Y was significantly larger than that in the other groups (p <0.01). The mean a/b ratio in group Y was significantly smaller than that in the other groups (p = 0.02). Fibulin-5 mRNA expression was not significantly different among the groups (p = 0.64). The relative intensity of fibulin-5 protein in group Y was significantly lower than that in group O (p = 0.006), with no significant differences between groups O and C (p = 0.14). CONCLUSIONS We showed that fibulin-5 is reduced in patients with PSP who are younger than 25 years.

Abstract
Pneumothorax is the accumulation of air in the pleural space. Pneumothorax may occur spontaneously (primary spontaneous pneumothorax, PSP). Chest tube drainage (CTD) is the most common choice for treatment of PSP. This study aimed to evaluate patients treated with CTD, regarding demographic and diagnostic characteristics, and to compare the effectiveness of apical and axillary approaches. We retrospectively analyzed a total of 217 patients with PSP regarding symptoms, duration of complaints, and treatment procedures. There were 196 (90.3%) male patients and mean age was 25.22 ± 5.37 years. The approach of CTD was determined randomly; being performed with the apical approach on 93 (42.9%) and axillary on 124 patients (57.1%). There were no statistically significant differences between the two groups in terms of age, sex, BMI, collapse size, and complaint duration. However, a statistically significant relationship was determined between collapse size and leading symptoms where the significance was related to dyspnea (p < 0.001). This led to the thought that dyspnea increases with the increase of collapse size. The patients who were admitted to hospital in the later term when compared with others, had a larger collapse size (p < 0.001). This also led to the thought that collapse increases in relation to time due to late admission of patients. Hospitalization time was significantly shorter in patients who had apical CTD (p < 0.001). In conclusion, inserting the tube from the apex could shorten the treatment period.

Abstract
Pneumothoraces are classified as spontaneous, traumatic and iatrogenic. Spontaneous pneumothoraces that occur without recognized lung disease are termed primary spontaneous pneumothoraces (PSP), whereas those that occur due to an underlying lung disease are termed secondary spontaneous pneumothoraces. The aetiology of secondary, traumatic or iatrogenic pneumothoraces is not usually debated. However, the aetiology of PSP is potentially controversial and often debated. Therefore, PSP is the focus of this article. There are several purported causes, which include blebs, bullae, emphysema-like changes (ELC) and pleural porosity. The controversy is valid because of the importance of recurrence prevention. This article reviews the current available evidence for the causes of PSP. The causes of PSP are likely a combination ELC, pleural porosity and other potential factors.

Abstract
OBJECTIVE Video-assisted thoracic surgery (VATS) for treatment of spontaneous pneumothorax refractory to nonoperative management was first reported in children by Rodgers in 1986 (Ann Surg. 1986; 204:677-680). Small series have shown success with apical blebectomy, mechanical or chemical (talc) pleurodesis, or combination techniques. We report the largest pediatric series of VATS for primary spontaneous pneumothorax (PSP) to date, to assess outcomes and compare techniques. METHODS Retrospective review of all children undergoing VATS for PSP between 1999 and 2007 at 2 university-affiliated hospitals by the same group of surgeons. Mann-Whitney U tests and chi(2) used (P < .05 = significant). RESULTS Thirty-two patients underwent 41 VATS procedures (32 initial-30 unilateral, 2 bilateral; 9 subsequent-7 contralateral, 2 ipsilateral recurrences). Mean age at presentation was 16.5 years (range, 13-20 years). Blebs were identified at the time of VATS in 95% of patients, but in 12.5%, they were on lower lobes. Mean duration of postoperative air leak was 2.7 days, postoperative hospital length of stay was 5.0 days, and postoperative chest tube duration was 5.1 days; 2 patients required Heimlich valves, which were managed at home. Five different surgical techniques were used as follows: blebectomy plus mechanical pleurodesis had the shortest length of stay (4.3 days) and need for chest tube drainage (4.1 days) but had a higher recurrence risk (6% major, 16% minor) than blebectomy plus chemical pleurodesis. The risk of requiring an additional VATS procedure (ipsilateral or contralateral) was 28%. Mean follow-up was 46 months. CONCLUSIONS Blebectomy plus either mechanical or chemical pleurodesis were both associated with acceptable outcomes. Blebectomy plus chemical pleurodesis appears to have less risk of ipsilateral recurrence but longer postoperative stay and chest tube drainage.

Abstract
OBJECTIVE Primary spontaneous pneumothorax (PSP) is a frequent and problematic disease, but its underlying causes and pathophysiology remain unclear. This study examined whether anger, which is related to many psychosomatic diseases, is a psychosocial factor associated with first-onset PSP. METHOD We administered the State-Trait Anger Expression Inventory, Stress Response Inventory, Coping Scale, Beck Depression Inventory and Global Assessment of Recent Stress to 91 patients with first-onset PSP and to 77 patients with recent minor trauma as controls. RESULTS The scores on anger-in, anger-out, state anger and trait anger were significantly higher in the PSP group than in the control group. Logistic regression analysis revealed that low body mass index and trait anger could be associated with PSP. CONCLUSION We hypothesize that anger could play a role in the pathophysiology of PSP.

Abstract
BACKGROUND To determine the prevalence of blebs or bullae using thoracoscopy in young healthy adults, and to compare patient characteristics among those with and without blebs. METHODS Bilateral thoracoscopic evaluation of the lungs was performed in healthy individuals who were referred for thoracoscopic thoracic sympathectomy for essential hyperhidrosis. Participants were enrolled into a registry and followed for up to 9 years. RESULTS Analysis was performed on 250 consecutive cases. Blebs were observed in 15 of 250 individuals (6%; male, n = 6; female, n = 9; mean age, 25.3 years; range, 15 to 51 years). Individuals with blebs had a significantly lower body mass index (BMI) [mean +/- SD, 20.7 +/- 2.4 kg/m(2) vs 22.7 +/- 3.4 kg/m(2); p = 0.027] when compared to individuals without blebs, whereas all other parameters were similar. Blebs were most prevalent among slim individuals (BMI < 22 kg/m(2)) who smoked (odds ratio, 5.9; 95% confidence interval, 1.19 to 29.20). CONCLUSION Blebs were identified thoracoscopically in 6% of young healthy adults with no underlying lung disease. Low BMI in combination with smoking may have an important role in the development of pleural blebs in healthy young adults; however, these changes may not be responsible for future spontaneous pneumothoraces.

Abstract
Management of patients with a spontaneous pneumothorax continues to challenge clinicians. Recent guidelines help provide care pathways for these patients and highlight the many areas in need of additional study. Management options for spontaneous pneumothoraces should be selected based primarily upon a patient's clinical status. Observation or pleural air drainage, in selected patients, plays a significant role in patients with primary spontaneous pneumothorax. By contrast, pleural air drainage plays the central role in patients with a secondary spontaneous pneumothorax. Surgically directed recurrence prevention and air leak management are preferred for both primary and secondary spontaneous pneumothorax patients.

Abstract
A 16-year-old boy with Marfan's syndrome was admitted with progressive dyspnea due to a large spontaneous pneumothorax. Bullous pulmonary dysplasia was confirmed and pleural tube drainage did not affect the air leak. Complete recovery required surgical resection of the bulla responsible for the ongoing air leak. This case report highlights the issue of management for severe spontaneous pneumothorax in general, showing that the choice of treatment should not depend on the presence of pulmonary bullous dysplasia but on the clinical evaluation of the individual patient.

Abstract
Spontaneous pneumothorax (SP) continues to be a frequent management problem. The lack of universally accepted management guidelines and a myriad of treatment options contribute to the current heterogeneous approach to SP. Forthcoming guidelines may improve management. Meantime, simple observation in stable patients with a primary spontaneous pneumothorax (PSP) is reasonable, and encouraging smoking cessation is paramount. More aggressive management of a patient with a secondary spontaneous pneumothorax (SSP) is advisable and should include at least chest tube drainage with chest tube size selection key. Careful assessment of recurrence risk and early corrective intervention for patients with a persistent air leak will improve care of both PSP and SSP patients. If chest tube-directed pleurodesis is chosen for recurrence prevention, talc is the most successful agent available. However, no more than 5 g of talc should be utilized, given the potential increased risk for acute respiratory failure at higher doses, and patients should be advised of alternatives such as doxycycline. No overwhelming clinical outcome advantages for a thoracoscopic over a limited thoracotomy approach to SP management has been reported in any randomized controlled trial. Institutional experience with and the availability of thoracoscopy or limited thoracotomy should dictate the operative approach to SP recurrence prevention and air leak correction until further study clarifies the choice.
