Thymic tumors are very rare neoplasms in children and account for less than 1% of mediastinal tumors in pediatric patients. One-third of the pediatric patients present with symptoms related to the compression of the tumor mass on the surrounding anatomic structures, and paraneoplastic syndromes such as myasthenia gravis, pure red cell aplasia, acquired hypogammaglobulinemia, and connective tissue disorders, which rarely occur in children with thymic tumors. Herein, we report a case of thymic carcinoma mimicking the symptoms of a connective tissue disease with symmetrical polyarthritis accompanying myositis, fever, weight loss, and malaise in a 15-year-old male patient. To our knowledge, this is the first case pediatric thymic carcinoma accompany with severe polyarthritis and myopathy, thus we have reviewed the current literature regarding the cases of thymic malignancies coexisting with paraneoplastic syndromes in children., (© 2024 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Objectives: The objective was to describe changing patterns of etiological factors and treatment modalities for massive hemoptysis., Material and Methods: From January 2008-December 2012, the medical records of 58 massive hemoptysis patients were reviewed., Results: Fifty-eight patients, 44 were men (75.9%) and 14 were women (24.1%), with a mean age of 51.4 years (range= 19-84 years), were divided into three groups; surgical management (n= 37, 63.8%), conservative management (n= 14, 24.1%) and bronchial artery embolization (n= 6, 10.4%). One case (1.7%) had combined treatment modality; bronchial artery embolization was followed by surgical resection. Anatomical lung resections were the most preferred resection type in the surgical management group (n= 34, 91.9%). The most common etiological factor was bronchiectasis (n= 19, 32.8%); followed by bronchial cancer (n= 14, 24.1%). The duration of hospitalization in the surgical management group was 11.4 days (range= 4-24); whereas in the bronchial artery embolization group, hospitalization was only four days (range= 2-7) (p< 0.01). Prolonged air leak (n= 7; 18.9%) was the most common complication in the surgical management group., Conclusion: We emphasize that bronchiectasis was leading cause of massive hemoptysis. Surgical treatment remains the definitive therapy in the management of massive hemoptysis with decreased mortality rates over decades; whereas bronchial artery embolization is an effective therapeutic tool., Competing Interests: Conflict of Interest: All authors declare that there is no conflict of interest.

Background/aim: This retrospective study evaluated the clinical presentation, underlying lung disease, surgical indications, technique, treatment outcomes, and postoperative complications of pulmonary aspergilloma., Materials and Methods: We evaluated 77 patients who underwent pulmonary resection of an aspergilloma at Atatürk Chest Diseases and Thoracic Surgery Research and Training Hospital between January 2000 and December 2013. The initial operations were 4 pneumonectomies, 24 lobectomies, 9 lobectomy plus myoplasties, 10 segmental resections, and 30 wedge resections. Six reoperations were carried out to deal with postoperative complications: 1 myoplasty, 2 completion lobectomies plus myoplasties, 2 myoplasties with rib resections, and 1 completion lobectomy., Results: The subjects comprised 53 males (mean age: 44.26 (range: 10-73) years) and 24 females (mean age: 48.25 (range: 26-70) years). The most common indication for surgery was hemoptysis in 52 patients (67.53%). The most common underlying lung disease was tuberculosis in 37 patients (48.05%). Forty patients (51.94%) had a simple pulmonary aspergilloma and 37 (48.05%) had a complex pulmonary aspergilloma. Major complications occurred in 18 patients (23.37%). The postoperative mortality rate was 3.89%, with 3 patients dying., Conclusion: Surgical resection of pulmonary aspergilloma is the best way to prevent recurrent hemoptysis with low morbidity and mortality.

Introduction: Pulmonary Langerhans cell histiocytosis (PLCH) is a rarely seen disease of younger population. Almost all of the patients were smoker. In this study we aimed to evaluate the characteristics, diagnosis, treatment modalities and prognosis of 11 cases with PLCH., Materials and Methods: We retrospectively reviewed our case series of eleven patients who were pathologically diagnosed as PLCH. The median age was 35 years (19-51) and male to female ratio (M/F) was 5/6. All of the patients were symptomatic. The most common symptoms were dyspnea (81.8%) and dry cough (72.7%). Mean duration of the symptoms was 10.8 months. All patients except two of them were smoker (81.8%). All patients were also passive smokers., Results: Bilateral cystic appearance (n= 9, 81.8%), interstitial findings [septal and peribronchovascular thickening (72.7%) and nodular pattern (54.5%)] were common radiological findings. Spontaneous pneumothorax was present in two cases. All patients were diagnosed with surgical biopsies (90.9%) or transbronchial parenchymal biopsy (9.1%). Smoking cessation (81.8%) and immunosupression therapy (methylprednisolone) were the treatment modalities. Mean follow-up period was 5.40 ± 1.78 years. Generally, symptoms were improved with smoking cessation or methylprednisolone therapy. One patient was readmitted to our clinic with recurrent pneumothorax. In conclusion, it should be kept in mind that passive smoking is also responsible in the pathogenesis of PLCH., Conclusion: Exact consensus for PLCH treatment was not present except a few recommendations. In the future, with the understanding of the pathogenesis of the disease, new therapeutic agents will be discovered for this rare condition.

We have evaluated our cases of "Kergin" pneumonectomy in which a bronchial flap of the medial part of the right main stem bronchus was created during right pneumonectomy and was turned upward to cover the lateral airway defect at the level of the carina. Five male patients with a mean age of 53.6 underwent "Kergin" pneumonectomy due to nonsmall cell carcinoma arising from right upper lobe entrance, which does not allow a classical pneumonectomy. Postoperative pathology stagings were stage IIB in 1 patient and stage IIIA in 4 patients. Any operative mortality or short-term complication was not observed. Two of the patients died in the second year of follow-up. "Kergin" pneumonectomy is a rarely performed procedure with acceptable morbidity and mortality and good lung cancer resection. Actually, our current report of five cases will be one of the largest series of "Kergin" pneumonectomy., (Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Objective: Recent studies have shown that tumor cell adhesion molecules CD44 and matrix metalloproteinases (MMP-2) are expressed strongly in many tumors and associated closely with invasion and metastasis of these tumors. Although solitary fibrous tumors (SFT) have a good prognosis, a minority behave malignantly. The aim of this study was to analyze the correlation between CD44 and MMP-2 expression with histopathological parameters in SFT., Material and Method: Haemotaxylin-Eosin stained sections of 10 patients with SFT were reexamined for evaluation of histopathological parameters. Immunostaining of CD44 and MMP-2 was performed by using the streptavidin-biotin method with mouse monoclonal antibody., Results: Our cases consisted of three male and seven female patients with a mean age of 54.5 years. Three patients had a history of asbest exposure. Complete resection was performed in 2 malignant (multiple masses) and 8 benign SFT cases. One intrapulmonary tumor was treated with pneumonectomy. 3 cases originated from the right and 7 from the left hemithorax. Tumor size ranged from 5 to 27cm. All cases expressed strong CD44. Only 2 malignant SFT and intrapulmonary SFT expressed focal MMP-2., Conclusion: Although MMP-2 positivity was observed in 2 malignant cases, CD44 positivity was not associated with malignancy criteria in solitary fibrous tumors.

Background: Sleeve resection is an advanced technique that was developed as an alternative to pneumonectomy. This study evaluated our cases of sleeve resection for squamous cell carcinoma of the lung and compared the outcomes with the literature reports., Methods: In total, 26 bronchial, 5 bronchovascular, and 3 vascular sleeve lobectomies were performed between January 2000 and July 2005 in our clinic. Age, gender, operations, postoperative diagnosis and staging, and postoperative morbidity and mortality were evaluated., Results: Sleeve resections were performed in 34 patients. All patients were male, with a mean age of 59.4 years. The operations consisted of 16 right upper, 14 left upper, and 1 left lower sleeve lobectomies and 3 superior sleeve bilobectomies. The most common postoperative pathological staging group was stage IIb (32.3%). Operative mortality was 5.9% (n=2). Postoperative morbidity was 20.5% (n=7), including 4 prolonged air leaks plus empyema, 1 prolonged air leak, 1 postoperative bleeding needing revision, and 1 severe bronchostenosis; of these, 6 had persistent atelectasis. The local tumour recurrence rate was 11.7% (n=4). The median survival time and 5-year survival were 36 months and 42%, respectively., Conclusions: Sleeve resection proved to be good therapy for lung cancer and has a lower morbidity and mortality than standard pneumonectomies and results in better lung function and quality of life. The anastomosis-related complications are experience-related technical complications and training thoracic surgeons to perform SRs at experienced centres will reduce the morbidity associated with SRs., (Copyright (c) 2010 Australasian Society of Cardiac and Thoracic Surgeons and the Cardiac Society of Australia and New Zealand.

Background: Echinococcosis is a near-cosmopolitan zoonosis caused by adult or larval stages of tapeworms (cestodes) into the genus Echinococcus (family Taeniidae). It was demonstrated that platelets were capable of killing parasites independent from leukocytes., Purpose: The aim of our study was to examine mean platelet volume (MPV), platelet mass (PM) and platelet count (PC), which are practical indicators of platelet activity in preoperative and postoperative periods of the patients with hydatid cyst., Methods: In this retrospective study we evaluated 72 patients admitted to clinic of chest surgery with a diagnosis of pulmonary hydatid cyst in our hospital between January, 2006, and October, 2008. The MPV, PC, and PM were evaluated by complete blood count. PM was calculated by multiplying MPV and PLT., Results: PREOPERATIVE MPV VALUES OF THE PATIENTS WAS FOUND TO BE SIGNIFICANTLY HIGHER THAN POSTOPERATIVE MPV VALUES (MEAN: 8.07±0.83, 7.78±0.87, p= 0.002). Preoperative PM values (median: 2456.75, range: 1013.70-5046.60) was found to be higher when compared to postoperative PM values (median: 2280.80, range: 134.20-4042.60) (p= 0.039). PC values were not significantly different between two periods (Preoperative-postoperative PC mean values: 320.48±98.42, 307.29±96.45, p= 0.286)., Conclusion: In this study, we demonstrated that there were no statistical difference in PC for both periods but, MPV and PM were found statistical higher than postoperative period in preoperative period. PM and PM can be used as markers of disease activity in patients who undergo surgical resection of hydatid cyst.

Background: Angiogenesis is an early step in tumor progression, and vascular endothelial growth factor (VEGF) is an important angiogenic factor. In this study, we investigated the prognostic significance of VEGF immunostaining in tumor tissues of non-small cell lung cancer (NSCLC) patients during a 5-year follow-up period., Methods: The study comprised 50 male patients diagnosed with NSCLC with a mean age of 57.26 +/- 8.64 years (range: 40-74 years). All patients had early stage NSCLC and none of the patients received chemo- or radiation therapy before surgery. VEGF immunostaining was performed in tumor tissues and immunoreactivity was graded as negative (0-10%), weak (10-50%), and strong (>50% tumors are stained)., Results: VEGF staining was weak in 20 (40%) specimens and strong in 13 (26%) specimens, whereas VEGF staining was negative in 17 (34%) specimens. Strong VEGF staining showed a significant correlation with both short time of relapse (p = 0.0001) and short survival (p = 0.0005). Multivariate analysis using Cox regression model was performed to determine the independent prognostic factors. Age (p = 0.029, OR: 1.05), tumor stage (p = 0.001, OR: 14.89), and VEGF staining (p = 0.006, OR: 4.65) were all found as independent prognostic factors in NSCLC., Conclusions: Strong VEGF immunostaining in tumor tissues was found to be an important prognostic factor for time to relapse and survival in patients with early stage disease.

Objective: Large series about pulmonary sequestration from a single institute are rare in the literature. In this study, we aimed to evaluate diagnosis, treatment, and outcomes of pulmonary sequestration in a single institute., Methods: Records of patients with pulmonary sequestration between January 1982 and January 2006 were reviewed retrospectively. Age, sex, symptoms, diagnostic procedures, operative findings, operative techniques, postoperative complications, and follow-up results were evaluated., Results: Twenty-seven patients, 17 male and 10 female, with an average age of 23.3 were operated on for pulmonary sequestration. Twenty patients had preoperative symptoms including recurrent pneumonia attacks, chest pain, hemoptysis, and shortness of breath. Chest radiography, thoracic computed tomography, aortography, magnetic resonance imaging, and bronchoscopy were used as diagnostic methods. Of the cases, 19 (70%) were intralobar pulmonary sequestration and 8 (30%) were extralobar pulmonary sequestration. Surgical procedures were lower lobectomy in 18 and segmentectomy in 1 of the patients with intralobar pulmonary sequestration and simple mass excision in all of those with extralobar pulmonary sequestration. Postoperative histopathologic examinations excluded any other alternative diagnosis. Furthermore, it detected an aspergilloma ball in 1 of the intralobar pulmonary sequestration specimens. Two patients had a postoperative complication (prolonged air leak in 1 patient and empyema in the other). During the follow-up period (mean 2.3 years), none of the patients presented a problem. No mortality was encountered., Conclusion: Owing to the potentially severe complications they can cause, pulmonary sequestrations should be removed whenever they are diagnosed. Since careful dissection provides sufficient surgical comfort, preoperative identification of the aberrant vessels is not a rule for the success of the operation.

Objective: Though there is a gradual decrease in the prevalence of bronchiectasis, it is still a cause of mortality and morbidity among children in developing countries such as Turkey. We reviewed the morbidity and mortality rates and the outcome of surgical treatment for childhood bronchiectasis., Patients and Methods: Age, sex, etiological factors, symptoms, radiological examinations, surgical procedures, postoperative morbidity and mortality in patients aged 16 years and younger, operated for bronchiectasis between January 1991 and April 2006 in the Thoracic Surgery Clinic of Atatürk Training and Research Hospital for Chest Disease and Chest Surgery were reviewed retrospectively., Results: Between January 1991 and April 2006, 176 cases aged 16 and younger were operated for bronchiectasis. There were 95 females (54%) and 81 males (46%), with a mean age of 12.3 years (range: 3.4-16 years). The most common cause of bronchiectasis was lung infection (n: 87, 49.4%). Main symptoms were coughing (n: 167, 94.9%), sputum (n: 139, 79%), hemoptysis (n: 78, 44.3%), and fever (n: 77, 43.7%). Mean duration of the symptoms in patients who were operated was 3.8 years (range: 0-7.6 years). Cases underwent a total of 201 operations: 19 cases had bilateral surgical resection and 6 cases had completion pneumonectomy. Majority of cases had complete resection (n: 165, 93.75%) while only 11 cases (6.25%) had incomplete resection. Mean duration of hospitalization was 8.9 days (range: 5-39 days). The outcome, based on the responses of patients postoperatively, was 'perfect' in 129 cases (73.3%), 'improved' in 41 cases (23.3%), and 'no changes' in 6 cases (3.4%). The mean follow-up after surgery was 4.3 years (range: 14 months to 7.2 years), mortality was 0% and morbidity was 13% (n: 23)., Conclusion: With acceptable mortality and morbidity rates and high chance of cure after complete resection, surgical treatment is a successful and reliable method of treatment in childhood bronchiectasis that yields marked improvement in the quality of life.

Objective: To present a case of hydatid disease of the first rib as a rare cause of thoracic outlet syndrome., Clinical Presentation: A 57-year-old female patient who had suffered from pain on the left shoulder radiating to the arm and numbness and weakness on the left arm for 3 months was admitted to our hospital. She had undergone an operation due to a mass lesion of the first rib compressing the thoracic outlet which was detected in the preoperative examinations. During the intraoperative examination it was decided that the lesion was a hydatid cyst and the first rib was totally resected., Conclusion: This report shows that hydatid disease should be taken into consideration amongst the tumoral diseases of the first rib as a very rare cause of thoracic outlet syndrome., (Copyright (c) 2007 S.

Aim: Intraoperative frozen section examination (FSE) is an important tool for determining how extensive a surgical procedure needs to be. In this study we reviewed the indications for FSE, the correlation between FSE and postoperative histopathology, and the contribution of intraoperative FSE in determining the extent of the surgical procedure., Methods: A total of 744 FSE performed in 721 patients between January 1995 and January 2004 were reviewed retrospectively. The FSE were divided into 7 groups according to the indications of the request for frozen section. False positivity and false negativity were evaluated., Results: The indications for FSE included intraoperative diagnosis of pulmonary masses (311, 41.8%), determination of N2 status with mediastinoscopy and mediastinotomy (153, 20.6%), staging of pulmonary carcinomas during the operation (86, 11.6%), assessment of the margin of bronchial surgical resection following pulmonary resection (54, 7.2%), presence of solitary pulmonary nodules (75, 10.1%), presence of mediastinal masses (39, 5.2%), and pleural thickening (26, 3.5%). When compared to postoperative paraffin sections, FSE was found to have a 1.9% (8) rate of false negatives and a 0.2% (1) rate of false positives (P < 0.001)., Conclusions: Intraoperative FSE in thoracic surgery is a rather reliable method. When FSE indicates malignancy, it is a valuable guide in directing the extent of the ongoing surgical procedure. However, when FSE indicates a benign lesion, surgeons should interpret this in the light of the patient's clinical and radiological features and the lesion's macroscopic nature when deciding how extensive an operation needs to be.

Purpose: Majority of tracheobronchial foreign body aspirations occur in paediatric age group and may constitute a life hazard. We examined the relationship between the time of admittance and complications in children with tracheobronchial foreign body aspiration., Material and Methods: Sex, age, time of admittance, presenting symptoms, radiological findings, and the nature of the foreign body were reviewed retrospectively in patients aged 16 and under follow-up for tracheobronchial foreign body aspiration between January 1990 and January 2005. Cases were randomly assigned into 6 groups based on admittance times., Results: Within 15-year period, 263 children under the age of 16 were followed-up for tracheobronchial aspiration of foreign body. The most commonly aspirated foreign bodies included sunflower seed, peanut, hazelnut, walnut. While the pathology could be detected radiographically in 80.3% (n : 211) of the cases, in 19.7% (n : 52) radiology was normal. All cases had rigid bronchoscopy under general anaesthesia. In 220 cases foreign body was detected and could successfully be removed in 209 cases. The remaining 11 cases required bronchotomy or pneumotomy to remove the foreign body. Among 679 cases operated for bronchiectasis during the same period, 22 cases (3.2%) had foreign body as the aetiology. No complications were observed when the patients presented to the hospital within the first 24 hours after the aspiration while fever, purulent sputum, haemoptysis and bronchiectasis were noted in those presented later. Most of the complications were medically treated., Conclusion: Paying medical attention within the first 24 hours after the aspiration of foreign bodies is critical in order to accomplish a complication-free course. Organic foreign bodies and retention period of 30 days and over, constitute major risk factors in the development of bronchiectasis. It is advisable to perform bronchoscopy in the early stages of all suspected cases to avoid serious complications such as bronchiectasis.

The diagnosis and management of pulmonary hydatid disease represents an important clinical problem in areas of the world endemic to echinococcal infection. We report two patients, ages 14 and 34, respectively, who were admitted to our clinic for investigation of nonresolving pneumonia. Neither had responded to antibiotics prior to admission. Chest x-rays demonstrated lobar collapse and consolidation in both patients. Fiberoptic bronchoscopy revealed laminated membrane of hydatid cyst occluding the bronchus of apicoposterior and anterior segmental bronchi of the left upper lobe in the first patient and the anterior segment of the right upper lobe in the second patient. The diagnoses were confirmed at the time of surgery.

Objective: A rib fracture secondary to blunt thoracic trauma is an important indicator of the severity of the trauma. In the present study we explored the morbidity and mortality rates and the management following rib fractures., Methods: Between May 1999 and May 2001, 1417 cases who presented to our clinic for thoracic trauma were reviewed retrospectively. Five hundred and forty-eight (38.7%) of the cases had rib fracture. There were 331 males and 217 females, with an overall mean age of 43 years (range: 5-78 years). These patients were allocated into groups according to their ages, the number of fractured ribs and status, i.e. whether they were stable or unstable (flail chest)., Results: The etiology of the trauma included road traffic accidents in 330 cases, falls in 122, assault in 54, and industrial accidents in 42 cases. Pulmonary complications such as pneumothorax (37.2%), hemothorax (26.8%), hemo-pneumothorax (15.3%), pulmonary contusion (17.2%), flail chest (5.8%) and isolated subcutaneous emphysema (2.2%) were noted. 40.1% of the cases with rib fracture were treated in intensive care units. The mean duration of their stay in the intensive care unit was 11.8+/-6.2 days. 42.8% of the cases were treated in the wards whereby their mean duration of hospital stay was 4.5+/-3.4 days, while 17.1% of the cases were followed up in the outpatient clinic. Twenty-seven patients required surgery. Mortality rate was calculated as 5.7% (n=31)., Conclusions: Rib fractures can be interpreted as signs of significant trauma. The greater the number of fractured ribs, the higher the mortality and morbidity rates. Patients with isolated rib fractures should be hospitalized if the number of fractured ribs is three or more. We also advocate that elderly patients with six or more fractured ribs should be treated in intensive care units due to high morbidity and mortality.

Objective: With the changing clinical presentation and histopathological pattern, carcinoids are now considered as a distinct and well-defined group in the neuroendocrine tumour scale. Surgery, especially parenchyma-sparing operations, are the treatment of choice for carcinoids., Methods: Over a 25-year period, 83 patients with typical carcinoid tumour underwent thoracotomy on in our institution. The records of the patients were reviewed and the results were evaluated., Results: The diagnosis was made with radiological methods and bronchoscopy. Cough and recurrent pneumonia were the most common symptoms. A variety of surgical procedures were performed. Thirty of the 83 patients underwent tissue-saving operations. Twenty patients underwent bronchotomy excision, eight were managed with sleeve or partial sleeve resective procedures, and two underwent segmentectomy., Conclusions: Conservative surgery is the treatment of choice of carcinoids, which were histologically typical and anatomically endobronchial. Especially for polypoid type carcinoids and for selected cases with sessile type, bronchotomy with simple excision and sleeve resections is a simple and effective method. As these types of operations produce a better functional result, they should be encouraged in these patients.

Objective: Hydatid disease is a parasitosis and endemic in many sheepraising areas; it is still an important health problem in Turkey. We report our experience with childhood hydatid cyst and discuss the concepts of treatment., Methods: The clinical courses of 128 children with thoracic and liver hydatid cyst operated on from 1994 to 2000 were reviewed. The group consisted of 71 boys and 57 girls aged from 8 months to 16 years. Intact cysts were found in 144 patients and ruptured cysts in 68., Results: In the postoperative course we have encountered 20 perioperative complications in 16 patients. The most common complication was residual pleural space and delayed air leakage, which occurred in 9 patients. There was no early death., Conclusion: Surgery is the treatment of choice for most patients with pulmonary hydatid disease. The aim of surgery is evacuation of the cyst, removal of the endocyst, and management of the residual cavity. Conservative surgical methods that preserve lung parenchyma should be preferred.

Background: Surgical treatment may be necessary in childhood chronic pleural empyema., Methods: Over a 21-year period 642 children with pleural empyema were hospitalized and 104 of them underwent surgical treatment. The records of the children who underwent surgery for the treatment of empyema were retrospectively reviewed to describe the role, indications, and results of surgical treatment of childhood chronic pleural empyema., Results: Etiologic diseases or conditions leading to empyema were pneumonia in 69 patients, tuberculosis in 13, hydatid cyst in eight, postpneumonectomy empyema in five, and other causes in nine patients. Indications for surgery were severe pleural thickening in 54 cases (51.9%), trapped lung in 36 cases (34.6%), loculated empyema in eight cases (7.7%) and broncho-pleural fistula in six cases (5.8%). Operations performed were decortication in 90 patients, pulmonary resection and decortication in seven, muscle flap closure in five, and pneumonectomy in two. Success rates in the treatment of nonspecific and tuberculous empyema were 93% and 54%, respectively., Conclusions: Surgical treatment is still necessary in childhood pleural empyema in developing countries, and success rates are very high in nonspecific pleural empyema and acceptable in tuberculous pleural empyema.
