Comparison of early recurrence in young-onset primary spontaneous pneumothorax following surgery using different covering methods.

Objectives: The treatment of primary spontaneous pneumothorax not only involves bulla resection via video-assisted thoracic surgery but also covers the lesion. Ideal treatment should minimize adhesions and reduce the recurrence rate. This study aimed to explore different covering methods and compare the frequency of early recurrence for each covering method.

A component of high-grade fetal lung adenocarcinoma diagnosed as the cause of lymph node metastasis.

High-grade fetal lung adenocarcinoma (H-FLAC) is a rare type of tumor. There have been no reports demonstrating the degree of metastatic susceptibility of this tumor type. In this report, we describe a case in which 15% of the adenocarcinoma components were H-FLAC diagnosed as the cause of lymph node metastasis.

[Invasive Mucinous Adenocarcinoma that Invades the Wall of a Cystic Lesion:Report of a Case].

Invasive mucinous adenocarcinoma (IMA) is a rare and special type of lung adenocarcinoma. We report a case of IMA presenting as a cystic lesion in the S10 of the right lung, diagnosed by surgical biopsy and treated with right lower lobectomy. The patient was a 60-year-old man who was found to have a 10-mm-sized frosted ground-glass opacity with a 10-mm-sized air space in the S10 of the right lung while undergoing follow-up after renal cancer surgery in 2018.

[Inflammatory Polyp due to Peanut Aspiration, Needed to Differentiate from Malignant Tumor: Report of a Case].

The patient was in his 70s. He was addmitted to our hospital because of obstructive pneumonia for 3 months. Chest computed tomography( CT) showed a nodule at the base of the right B8, obstructing the basal branch, with consolidation of the peripheral lung.

[Echinococcosis Detected by a Solitary Shadow in the Lung].

Here we report a rare case of pulmonary coin lesion due to echinococcosis. An woman in her 60s who has no symptom was found a nodular shadow of the left lung incidentally. Since the nodule was enlarging, surgical treatment was done.

Parietal pleural small holes found in patients with primary spontaneous pneumothorax associated with relatively mild chest wall flatness: a retrospective study.

Background: During surgery for spontaneous pneumothorax, parietal pleural small holes (PPSHs) are occasionally found around the apex of the intrapleural space; however, this has not been well recognized. Additionally, chest wall flatness is usually observed in patients with primary spontaneous pneumothorax (PSP) and PPSHs. This study aimed to investigate the prevalence of PPSH and evaluate the characteristics of patients with PPSH.

Insufficient initial treatment but good recovery after diagnosis of pulmonary actinomycosis.

Actinomycosis is an infrequent invasive bacterial disease. Although multiple different clinical features of actinomycosis have been described, pulmonary actinomycosis (PA) is a rare but challenging diagnosis and complete cure to make. Here we report the case of a 41-year-old Asian woman who had a mass-like consolidation in the right middle lung field.

[Birt-Hogg-Dubé Syndrome Incidentally Found at Chest Trauma;Report of a Case].

Birt-Hogg-Dubé syndrome (BHDS) is usually diagnosed at the incidence of pneumothorax. A 65-year-old male fell from the stairs in his house and was injured. Chest computed tomography (CT) revealed fractures of right 1st rib and sternum and hematoma in mediastinum.

[Birt-Hogg-Dubé Syndrome Incidentally Found at Surgery for Idiopathic Hemopneumothorax;Report of a Case].

We suspected Birt-Hogg-Dubé syndrome (BHDS) from intraoperative findings of emergency operation for idiopathic hemopneumothorax. A 34-year-old man was delivered to our center due to sudden chest pain and dyspnea. Under the diagnosis of hemopneumothorax, emergency operation was performed.

[Assessment of Surgical Treatment for Chronic Pulmonary Aspergillosis].

Objectives: The purpose of this study is to assess retrospectively our treatment strategy for chronic pulmonary aspergillosis(CPA).

Patients And Method: From 2002 to 2015, 11 patients underwent pulmonary resection for CPA in our hospital. Six patients were diagnosed simple pulmonary aspergilloma (SPA) and 5 were chronic progressive pulmonary aspergillosis(CPPA).

[Bronchial Foreign Body Removed by Bronchotomy from the Anterior Side of the Pulmonary Hilum；Report of a Case].

Although many bronchial foreign bodies can be extracted by flexible bronchoscopy, it is sometimes difficult because of size and form of foreign bodies. A 78-year-old man who had been bedridden for 1 year presented to another hospital due to fever and hemoptysis. Chest X-ray showed a dental crown in the left inferior lobe bronchus.

[Thymoma with Hemorrhage and Necrosis Presenting with Fever and Chest Pain;Report of a Case].

A 53-year-old man was admitted to our hospital for treatment of fever and chest pain. Chest computed tomography showed an anterior mediastinal cystic tumor 39×57 mm in size surrounded by fat with edema and left pleural effusion. After one course of antibiotic administration, the edema of fat surrounding the tumor disappeared and the patient underwent scheduled tumor resection with thymectomy through a median sternotomy.

[Complete resection of a posterior mediastinal tumor after preoperative identification of artery of Adamkiewicz].

The thoracolumbar spinal cord receives its blood supply primarily from the artery of Adamkiewicz (AA), a branch of thoracolumbar intercostal arteries. Aortic cross-clamping during operation for descending aortic aneurysms can cause paraplegia due to spinal cord ischemia secondary to low blood flow through the AA. A 69-year-old woman was diagnosed with a left posterior mediastinal tumor measuring 66 mm.

[Video-assisted thoracoscopic surgery for intrathoracic extramedullary hematopoiesis].

Extramedullary hematopoiesis (EMH) is associated with hematopoietic disorders, with intrathoracic EMH being a rare presentation. We report a case of posterior mediastinal EMH masses in 63-year-old male with congenital hemolytic anemia. Multiple paravertebral masses with dense soft parts and well defined borders, but without accompanying calcification or bone erosion were identified on a chest computed tomography (CT) scan during an examination for another disease.

Spontaneous thymic hemorrhage in an adult.

Spontaneous thymic hemorrhage in a normal thymus in neonates and infants has been reported in the literature. Only one case of spontaneous thymic hemorrhage in an adult has been reported to our knowledge. We herein report the case of an adult who had a cardiac operation 26 years previously and who was on anticoagulation.

[Evaluation of long-term results in patients who underwent reconstruction of thoracic wall with curved metal plates].

Between 1992 and 2011, 22 patients underwent surgery of reconstruction of thoracic wall with curved metal plates for multiple rib fracture and resection of thoracic wall tumor. They were divided into 2 groups according to original disorders. Twelve cases of group A accepted surgical stabilization of traumatic multiple rib fractures with the metal plates fixed on the fractured ribs as an external brace.

[Prognostic factors of resected metastatic lung tumor originated from renal cell carcinoma].

We performed retrospective analysis of 22 cases who received pulmonary resection of metastases originated from renal cell carcinoma between 1997 and 2011. Patients comprised 18 men and 4 women with a mean age of 63 years (range, 39~79). The total pulmonary resection was 30 times, lobectomy was performed 5 times and wedge resection was 25 times.

The cervical anterior approach for the resection of superior posterior neurogenic tumor: a case report.

Many approaches for resection of the superior mediastinal tumors have been reported. We introduce an approach, which we call the cervical anterior approach. This approach is only cervical and does not require a sternotomy.

Long-term survival after complete mediastinal lymph node resection and lobectomy in patients with bulky N2 non-small cell lung cancer.

Background: At Juntendo University Hospital, Japan, two patients with complete resection of bulky N2 non-small cell lung cancer (NSCLC) has survived over the long term. Therefore, we decided to retrospectively study patients who also had a complete resection of the tumor including the "bulky" superior mediastinal node for the purpose of reviewing covariates that might be related to the favorable outcome.

Methods: We retrospectively analyzed the relation between covariates and survival after complete lobectomy and mediastinal lymph node resection (from April 1997 to August 2007) in 15 patients with bulky N2 NSCLC, lymph nodes greater than 2 cm in short-axis diameter (bulky nodal disease) measured on preoperative chest computer tomography.

Impact of renal failure on the tumor markers of mesothelioma, N-ERC/mesothelin and osteopontin.

Background: Knowledge of the characteristics and effective use of tumour markers for mesothelioma is essential for early-stage diagnosis of mesothelioma. We examined whether renal dysfunction influences blood concentrations of promising new tumour markers, N-ERC/mesothelin (N-ERC) and osteopontin (OPN), to an important degree.

Patients And Methods: Levels of serum N-ERC and plasma OPN in 32 patients with chronic renal dysfunction, 22 of whom were on hemodialysis (CKD group), and 102 healthy volunteers were measured.

Use of silicone gel sheets for prevention of keloid scars after median sternotomy.

Purpose: A keloid scar often appears at the incision site of patients after median sternotomy. Use of silicone gel to treat hypertrophic burn scars and fresh incisions has yielded encouraging results. In this study, we report our experience with the preventive use of silicone gel sheets for keloid scars after median sternotomy.

Experience of silicone gel sheets for patients with keloid scars after median sternotomy.

Purpose: It is often difficult to control hypertrophic scars and keloids with drug therapy, steroid injection, surgery, radiation therapy, laser, or wound pressing. Use of silicone gel to treat hypertrophic burn scars and fresh incisions has yielded encouraging results. We report our experience of silicone gel sheets for patients with keloids following median sternotomy.
