Spontaneous Pneumothorax Complicating Miliary Tuberculosis: About a Case at the “Centre Medical Principal De La Gendarmerie Nationale Du Mali”

Introduction: Spontaneous pneumothorax is a rare but serious complication of tuberculosis. Miliary tuberculosis (MT) is a severe form of tuberculosis secondary to hematogenous spread of Mycobacterium tuberculosis. Objective: To report a case of MT complicated by pneumothorax. Methodology: This was a 25-year-old patient, farmer, followed up at the Pneumo-phtisiology department of the CHU du Point G for MT whose condition was improving after the introduction of anti-tuberculosis chemotherapy. He consulted again after experiencing chest pain. Clinical and imaging revealed a Spontaneous pneumothorax complicating MT. The treatment combined anti-tuberculosis chemotherapy, chest drainage and respiratory physiotherapy. Outcome was favorable with improvement of clinical and radiological signs. Conclusion: Pneumothorax complicating MT requires a reflective diagnostic approach and rapid management to improve its prognosis.

Nonintubated uniportal video-assisted thoracoscopic surgery for primary spontaneous pneumothorax

Objective： The objective of the current study was to evaluate the feasibility and safety of nonintubated nniportal video-assisted thoracoscopic surgery （VATS） for the management of primary spontaneous pneumothorax （PSP）. Methods： From November 2011 to June 2013, 32 consecutive patients with PSP were treated by nonintubated uniportal thoracoscopic bullectomy using epidnral anaesthesia and sedation without endotracheal intubation. An incision 2 cm in length was made at the 6th intercostal space in the median axillary line. The pleural space was entered by blunt dissection for placement of a soft incision protector. Instruments were then inserted through the incision protector to perform thoracoscopic bullectomy. Data were collected within a minimum follow-up period of 10 months. Results： The average time of surgery was 49.0 rain （range, 33-65 rain）. No complications were recorded. The postoperative feeding time was 6 h. The mean postoperative chest tube drainage and hospital stay were 19.3 h and 41.6 h, respectively. The postoperative pain was mild for 30 patients （93.75%） and moderate for two patients （6.25%）. No recurrences ofpneumothorax were observed at follow-up. Conclusions： The initial results indicated that nonintubated uniportal video-assisted thoracoscopic operations are not only technically feasible, but may also be a safe and less invasive alternative for select patients in the management of PSP. This is the first report to include the use of a nonintubated uniportal technique in VATS for such a large number of PSP cases. Further work and development of instruments are needed to define the applications and advantages of this technique.

Video-assisted thoracoscopic surgery (VATS) for bilateral primary spontaneous pneumothorax

Objective： To review our experience of the treatment of bilateral primary spontaneous pneumothorax （PSP） by video-assisted thoracoscopic surgery （VATS）. Materials and methods： Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results： Twelve males and one female, with age ranging from 15 to 36 years （mean 23.1 years）, were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously （n=4） or sequentially （n=9）. The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients （84.6%） had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was （45.6±18.3） min （range 25-96 min） and （120.6±28.7） min （range 84-166 min） respectively for the non-simultaneous （second VATS for the recurrence of contralateral side after first VATS） and simultaneous （bilateral VATS in one operation） procedures. There was no postoperative mortality. However, prolonged air leakage （〉7 d） occurred in one patient （7.7%） who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions： VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side.

A single institution experience using the LigaSure vessel sealing system in video-assisted thoracoscopic surgery for primary spontaneous pneumothorax

This study sought to report our 6-year experience with the LigaSure vessel sealing system（LVSS） in videoassisted thoracoscopic surgery（VATS） for primary spontaneous pneumothorax.A series of 180 consecutive patients with primary spontaneous pneumothorax were operated on in our institution from May 2005 to December 2010.Intraoperatively,large lesions（bullae or blebs） with a diameter more than 2 cm were resected by staplers,and the residual lesions were treated by LVSS.LVSS was also used to ablate the apical area when no lesions were found.Conventional apical pleural abrasion was done in all cases.All patients were successfully treated using VATS with minimal perioperative bleeding.The mean operating time was 76 minutes（range,43-160 minutes） for single-side procedures and 169 minutes（range,135-195 minutes） for bilateral procedures,the mean number of applied staples was 1.93 per patient（range,0-8 days）,the duration of drainage was 3.8 days（range,2-15 days）,and the duration of hospital stay was 5.8 days（range,3-16 days）.Postoperative complications included persistent air leak（〉 5 days） in 11 cases（6.1%） and residual pneumothorax in 6（3.3%）.None required reoperation.The mean duration of follow-up was 57 months（range,24-105 months）.Recurrence was seen in three cases（1.7%）,and all underwent another operation thereafter.None of the lesions in the relapse cases received ablation with LVSS in the first operation.LVSS can optimize VATS for primary spontaneous pneumothorax and reduces the use of single-use staples.The method is safe,easy to use,and cost-effective and produces satisfactory results.

FAMILIAL SPONTANEOUS PNEUMOTHORAX

it is believed that there are some factors related with familial spontaneous pneumothorax. These factors are hereditary,homologous leucocytic antigen (HLA),α-antrypsin (α-AT) and lanky somatotype,According to the analysis or 7 cases with the disease and references review, in this paper,we believe that the familial spontaneous pneumothorax is related with HLA,and α-AT,ut not every patient has this relation. The phenotype of HLA and α-AT can he passed on to next generation from either father or mother. It is also believed that the formation of spontaneous pneumothorax in this group is related with the maldevelopment of local lung and bronchiole rather than with the lanky somatotype.

Matrix Metalloproteinase-9 Promoter Polymorphism in Primary Spontaneous Pneumothorax

Primary spontaneous pneumothorax （PSP） is a common clinical problem occurring in apparently healthy subjects. However emphysema like changes （ELC） in patients with （PSP） has been demonstrated, which is associated with the degradation of extraceilular matrix （ECM）. MMP-9 has been proposed to play a role in the development of emphysema and is involved in the digestion of （ECM）. Among several polymorphic changes reported in MMP-9 regulatory region, the C-1562T polymorphism increases its promoter activity Aim of the work： To test the hypothesis that the MMP-9 C-1562T polymorphism has a role in the occurrence of PSP. Subjects and Methods： MMP-9 （C-1562T） genotypes of 104 PSP patients and 97 healthy subjects （control） were determined by the polymerase chain reaction, followed by a restriction fragment length polymorphism analysis. Results： This study showed that the genotype frequency for MMP-9 1562 C 〉 T differed significantly between healthy individuals and PSP patients, with higher T allele in MMP-9 promoter in PSP patients, and the C/T ＋ T/T genotypes significantly modified the risk of developing PSP, and were associated with increased risk for PSP. Conclusion： MMP-9-1562C/T genotype may be a potentially indicative factor for susceptibility to PSP, that is, genotypes with the T allele significantly increase the risk of development of PSP.

Analysis of Recurrence and Influencing Factors of Spontaneous Pneumothorax After Thoracoscopic Surgery

This study was conducted to explore the factors that are influencing the recurrence of spontaneous pneumothorax after thoracoscopic surgery.Around 110 patients with spontaneous pneumothorax who underwent thoracoscopic bullectomy in Hebei Hospital from May 2017 to May 2021 were included in this study.The patients were divided into the recurrence group(15 cases)and the non-recurrence group(95 cases),and the influences of gender,age,smoking history,height,weight,operation time,the weight of the excised tissue,number of excised pulmonary bullae,postoperative chest tube maintenance time,duration of air leakage,and length of hospital stay on the recurrence of spontaneous pneumothorax after thoracoscopic surgery were investigated.This study found that the height/weight,operation time,duration of air leakage,number of pulmonary bullae removed,weight of the removed tissue,postoperative chest tube maintenance time,and duration of hospital stay in the recurrence group was 3.2±0.4,50.9±1.2,2.1±0.4,1.6±0.2,4.2±1.3,2.4±1.5 and 7.2±1.5,respectively.Meanwhile,the recurrence group was 2.6±0.3,50.8±1.3,1.3±0.2,1.8±0.9,4.4±1.2,4.1±1.7 and 6.9±1.6,respectively.After comparing the relevant factors between the recurrence group and the non-recurrence group,it was found that there was comparability between age,height/weight,duration of air leakage and postoperative chest tube maintenance time,where these factors were shown to affect the recurrence of spontaneous pneumothorax after thoracoscopic surgery,while gender,smoking,operation time,number of resected bullae,weight of resected tissue and length of hospital stay had no effect on recurrence after spontaneous pneumothoracoscopic surgery.In short,thoracoscopic bullectomy is the best clinical treatment for spontaneous pneumothorax,however the occurrence of recurrence of spontaneous pneumothorax after the operation,which is mainly influenced by the patient’s height/weight,postoperative air leakage duration,and chest tube maintenance time.Therefore,it is essential to pay attention to the surgical treatment of the patients,and fully identify the related factors of postoperative recurrence,thereby the follow-up clinical treatment can be carried out effectively.

Analyzing the CT Features of Primary Spontaneous Pneumothorax and Its Application Value

Objective:To explore the performance characteristics of CT examination in primary spontaneous pneumothorax(PSP)and the effect of pleurodesis on patients with PSP.Methods:Sixty-four patients with PSP,who received medical care in the Affiliated Hospital of Hebei University from January 2017 to December 2021,were selected as the research subjects,of which 40 were male and 24 were female patients.All 64 patients were examined by X-ray and CT;the density,enhancement,and morphology of the pneumothorax were observed and analyzed,and the classification of pneumothorax was done.Results:The clinical analysis of 64 patients with PSP showed that the number of cases with unilateral pneumothorax was 42,accounting for 65.63%,whereas the number of cases with bilateral pneumothorax was 22,accounting for 34.37%.Among the cases of unilateral pneumothorax,the number of cases with left pneumothorax was 26,accounting for 61.90%,whereas the proportion of cases with right pneumothorax was 38.10%.When examined by CT,the diagnostic coincidence rate of 64 patients with PSP was 73.44%;using X-ray examination,the diagnostic coincidence rate of 64 patients with PSP was 92.19%.Conclusion:The detection accuracy of CT is higher than that of X-ray examination,which may improve the treatment effect in PSP,ensure the accuracy of findings,and facilitate follow-up treatment as well as the effect of postoperative analysis.

Spontaneous Bilateral Pneumothorax in a Healthy Young Adult: A Comprehensive Case Report

Background: Spontaneous bilateral pneumothorax in healthy young adults is a rare and challenging condition that defies conventional diagnostic and etiological paradigms. This case report explores the presentation, diagnostic evaluation, management, and potential contributing factors in a 29-year-old male with no prior medical history who experienced bilateral spontaneous pneumothoraces. Aim: This case report aims to shed light on the complexities of managing spontaneous bilateral pneumothorax, particularly in the absence of common risk factors. It underscores the need for a thorough assessment and ongoing research to unravel the enigma surrounding this condition. Case Presentation: A healthy 29-year-old male presented with acute chest pain and shortness of breath, ultimately diagnosed with bilateral spontaneous pneumothoraces. Despite the absence of typical risk factors, advanced imaging techniques revealed valuable insights into the diagnosis and management of this unique presentation. Conclusion: Spontaneous bilateral pneumothorax in healthy individuals presents diagnostic challenges and raises questions about potential genetic predisposition, connective tissue disorders, and lifestyle-related triggers. While the acute phase was effectively managed, this case underscores the importance of interdisciplinary collaboration and ongoing research to comprehensively understand this condition.

Diagnosis and treatment of primary spontaneous pneumothorax

Primary spontaneous pneumothorax(PSP) commonly occurs in tall,thin,adolescent men.Though the pathogenesis of PSP has been gradually uncovered,there is still a lack of consensus in the diagnostic approach and treatment strategies for this disorder.Herein,the literature is reviewed concerning mechanisms and personal clinical experience with PSP.The chest computed tomography(CT) has been more commonly used than before to help understand the pathogenesis of PSP and plan further management strategies.The development of video-assisted thoracoscopic surgery(VATS) has changed the profiles of management strategies of PSP due to its minimal invasiveness and high effectiveness for patients with these diseases.

Erlotinib treatment for persistent spontaneous pneumothorax in non-small cell lung cancer： a case report

Spontaneous pneumothorax （SP） develops secondary to primary lung cancer. It has a very low incidence and accounts for less than 1% of all cases.1 Once SP develops, the prognosis is usually very poor, and majority of patients live no longer than 3 months.1,2Most patients with advanced stage can not undergo resection due to the poor general condition. Thus, chest tube drainage remains among the treatments of choice although it is not always completely effective in preventing recurrence. In refractory SP, patients would bear the chest tube for their whole life.3 Here we report a case of SP following chemotherapy in adenocarcinoma of the lung with multiple organs metastases. In this case, chest tube drainage was not effective in preventing recurrence of SP.However, the treatment was successful with oral erlotinib,an epidermal growth factor receptor tyrosine kinase inhibitor （EGFR-TKI）.

Postoperative management of spontaneous pneumothorax in arthroscopic shoulder superior capsular reconstruction:A case report and review of literature

Arthroscopic superior capsular reconstruction is an innovative technique for the irreparable rotator cuff tears,but spontaneous pneumothorax after surgery is very rare.The present case was a 66-year-old female with irreparable rotator cuff tears of the right shoulder,treated with the arthroscopic shoulder superior capsular reconstruction.The general anesthesia and operation went smoothly,but the patient experienced stuffiness in the chest and shortness of breath after recovery from anesthesia.Thoracic CT scans showed spontaneous pneumothorax in the right side,which was successfully treated by the conservative treatments(oxygen therapy)according to multidisciplinary team.Prompt and accurate early-stage diagnosis is necessary in controlling postoperative complications and standardized treatment is the key to relieve the suffering.Spontaneous pneumothorax after arthroscopic shoulder surgery has been rarely reported in previous literatures.

A rare occurrence of a hereditary Birt-Hogg-Dubésyndrome:A case report

BACKGROUND Birt-Hogg-Dubé(BHD)syndrome is a rare autosomal dominant disease caused by germline mutations in the folliculin(FLCN)protein gene,which usually manifests as cutaneous fibrofolliculoma,pulmonary cysts,renal cell carcinoma,and spontaneous pneumothorax.CASE SUMMARY A 26-year-old woman with no history of smoking was admitted to the Respiratory Department of our hospital due to intermittent wheezing that lasted for 8 mo.She had experienced recurrent spontaneous pneumothorax more than four times during the past 8 mo.After admission,the patient again suffered from left pneumothorax without a clear reason.Lung computed tomography(CT)showed multiple low-density cystic changes in both lungs.Physical examination on admission revealed multiple white dome-shaped papules in the neck,the nape,and behind the ear.In addition,the patient had a family history of spontaneous pneumothorax.Her mother had suffered from pneumothorax four times(at age 36,37,42,and 50 years).Her second maternal aunt had suffered from a right pneumothorax at the age of 40.The multidisciplinary diagnosis of BHD,which included the Respiratory Department,Radiology Department,Pathology Department,and Dermatological Department,was BHD and was later confirmed by family genetic testing.The same variation(FLCN gene)was found in the patient’s mother and aunt.CONCLUSION This case highlights the importance of multidisciplinary diagnosis and a treatment platform for the diagnosis of BHD.
