PURPOSE: This study was conducted to analyze the effects of virtual reality inspiratory muscle training and conventional inspiratory muscle training on diaphragm movement and pulmonary function in patients with thoracic restriction. METHODS: This study measured diaphragm movement, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and thoracic mobility (upper, middle, and lower trunk) under two different conditions. Forty young women between 19 and 24 years of age who had no history of orthopedic symptoms for the last 6 months were divided into experimental and control groups. The experimental group performed virtual reality inspiratory muscle training and diaphragm breathing, and the control group performed conventional inspiratory muscle training and diaphragm breathing. RESULTS: The control group showed a significant increase in all dependent variables except for lower trunk mobility and PEF. The experimental group showed a significant increase in all dependent variables except for lower trunk mobility. Particularly, the experimental group showed significant increases in diaphragm movement (p<.05), FVC (p<.05), FEV1 (p<.05), and PEF (p<.05) relative to the control group. CONCLUSION: We recommend inspiratory muscle training with a virtual reality program over conventional training to improve diaphragm movement and pulmonary function in patients with thoracic restriction.

The patient was 21-year old male who had gastrostomy and tracheostomy after swallowing lye-stuff in July 1971. He could restore his normal voice and breathing after removal of his destructed epiglottis obstructing his upper airway two years later. Pharyngogastrostomy was performed in Nov 1973. The esophagus which was totally obliterated in its full length was removed and the stomach was brought high up to the level of pharynx where it was anastomosed to the posterior wall of pharynx. His postoperative course was temporarily complicated by aspiration of small food into trachea which could be completely relieved with training, and he is doing his normal life quite well on the follow-up.

This report is a analysis of 72 cases of mediastinal tumors which are originated in mediastinum or probably metastasized from other organs, and classified on the basis of histopathological types. And all are experienced in the Depart. Thoracic and cardiovascular Surgery, National Medical Center from 1959 to April 1976. Among these cases, 58 cases were confirmed by histopathologically, and remained 14 cases were considered as mediastinal tumor by clinically and roentgenologically. In this series, dermoid cyst and teratoma was most frequent tumor among histopathologically confirmed cases(27.6%), and thymoma 20.7%, neurogenic tumors 17.2%, carcinoma 19%, lymphoid tumor 8.6% and others was 5.9%. The cases of not verified histopathologically were 14 cases. The main clinical symptoms were dyspnea on exertion or orthopnea (62.55%), productive or irritative cough (59.77%), decreased breathing sound (43. 09%). S.V.C syndromes was seen in 25.02%, and there were no definitive symptom in 4.2% of all cases. The main treatment method was surgical removal and irradiation therapy.

흉추 측면검사에서의 T-spine breathing technique을 실제 임상에서 사용되고 있는 4가지 검출기인 computer radiography (CR), charge coupled device (CCD), indirect digital radiography (IDR)와 direct digital radiography (DDR)을 사용하여 임상 유용성을 넓히고자 하였다. 화질 평가는 흉추 측면검사의 평가요소 중 5곳 (극돌기, 추궁근, 추체, 추간공, 추간)을 Image J 프로그램을 이용하여 관심영역을 정하고 신호 평균값과 표준편차를 구하여 대조도 잡음비와 신호 대 잡음비를 측정하여 비교하였다. 실험결과 4가지 검출기에서 T-spine breathing technique에서 극돌기, 추궁근, 추체, 추간공, 추간의 5곳 구조에서 우수하게 나타났다. 기존의 T-spine exhalation technique에 비해 T-spine breathing technique으로 촬영한 영상은 우수한 화질을 제공하므로 추후 심호기가 어려운 고령환자들에게 유용한 방법이라 사료된다. 그리고 4가지 검출기에서 contrast to noise ratio (CNR)와 signal to noise ratio (SNR) 같은 정량적인 수치를 제시함으로써 T-spine breathing technique의 적용 가능성을 나타내었다.

폐탈출증은 근골격으로 구성된 흉곽 밖으로 폐실질이 빠져나와 돌출되는 것으로, 최근까지 문헌으로 보고된 예는 300 례 미만이다. 환자는 늑골 골절을 포함한 외상을 입었던 과거력을 가진 37세와 57세 남자 이며 주소는 전흉부에 무통성의 부드러운 종괴로 호기시나 기침시 그 크기가 증가하였고, 흡기시 혹은 조용한 호흡시에는 감소하였다. 수술은 흉벽 결손에 대한 일차 봉합술을 시행하였으며, 술후 재발은 아직 까지 관찰되지 않았다 저자들은 지금까지 국내 발생보고 예가 없는 후천성 폐탈출증 2례를 수술 치험하였기에 문헌고찰과 함께 보고하는 바이다.

Objective: Motion-corrected averaging with a single-shot technique was introduced for faster acquisition of late-gadolinium-enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging while free-breathing. We aimed to evaluate the image quality (IQ) of free-breathing motion-corrected single-shot LGE (moco-ss-LGE) in patients with hypertrophic cardiomyopathy (HCM). Materials and Methods: Between April and December 2019, 30 patients (23 men; median age, 48.5; interquartile range [IQR], 36.5-61.3) with HCM were prospectively enrolled. Breath-held single-shot LGE (bh-ss-LGE) and free-breathing moco-ss-LGE images were acquired in random order on a 3T MR system. Semi-quantitative IQ scores, contrast-to-noise ratios (CNRs), and quantitative size of myocardial scar were assessed on pairs of bh-ss-LGE and moco-ss-LGE. The mean ± standard deviation of the parameters was obtained. The results were compared using the Wilcoxon signed-rank test. Results: The moco-ss-LGE images had better IQ scores than the bh-ss-LGE images (4.55 ± 0.55 vs. 3.68 ± 0.45, p < 0.001). The CNR of the scar to the remote myocardium (34.46 ± 11.85 vs. 26.13 ± 10.04, p < 0.001), scar to left ventricle (LV) cavity (13.09 ± 7.95 vs. 9.84 ± 6.65, p = 0.030), and LV cavity to remote myocardium (33.12 ± 15.53 vs. 22.69 ± 11.27, p < 0.001) were consistently greater for moco-ss-LGE images than for bh-ss-LGE images. Measurements of scar size did not differ significantly between LGE pairs using the following three different quantification methods: 1) full width at half-maximum method; 23.84 ± 12.88% vs. 24.05 ± 12.81% (p = 0.820), 2) 6-standard deviation method, 15.14 ± 10.78% vs. 15.99 ± 10.99% (p = 0.186), and 3) 3-standard deviation method; 36.51 ± 17.60% vs. 37.50 ± 17.90% (p = 0.785). Conclusion: Motion-corrected averaging may allow for superior IQ and CNRs with free-breathing in single-shot LGE imaging, with a herald of free-breathing moco-ss-LGE as the scar imaging technique of choice for clinical practice.

Six patients with flail chest were performed operative stabilization with Judet`s Struts.The indications of opertive stabilization were exploratory thoracotomy or laparotomy in 4 patients, and severe chest pain due to displaced ribs which deteriorated respiratory pattern and gas exchange in 2 patients. After operation, all patients became comfortable and complained less pain.Two patients restored spontaneous breathing without ventilator therapy and 2 patients were ventilated during 4 days and 5 days, respectively.There were no morbidity and mortality related to operative stabilization.

Congenital diaphragmatic eventration is a rare disease and generally accepted as an abnormally high position of part or all of the diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area. There were 4 cases of the congenital diaphragmatic eventration at the Dept. of Thoracic Surgery, Seoul National University Hospital, from 1957 to 1977. They were two boys and two girls and ranging from 1 day to 3 years of age. They were all repaired by surgical operation and one was expired postoperatively, another one was dead one year later due to complication. The ratio between right and left was 1:3 and their symptoms were cyanosis, dyspnea and frequent respiratory disease. In physical examination there was noted decreased breathing sound on the affected lung field and bowel sound was audible in some cases. Diagnosis was done by Chest X-ray and plication of the affected diaphragm was usually done in operation. There were noted atelectasis and cystic change of the affected side lung. And the liver, colon, spleen and small intestine were found in the dome of the eventrated diaphragm.

A 14-year-old castrated male Persian cat presented with a 2-week history of respiratory difficulty. On physical examination, the patient showed intermittent open-mouth breathing and thoracic auscultation revealed wheezing. Thoracic radiographs revealed a narrowed upper airway and pulmonary infiltration. Computed tomography detected a mass occluding the lumen of the trachea at the level of the entrance to the thorax, a mass causing right main bronchus stenosis, and a nodule on the right caudal lung lobe. Bronchoalveolar lavage cytology tentatively diagnosed a carcinoma. Tracheal mass resection was performed through tracheostomy. Histopathology confirmed the presence of tracheobronchial carcinoma. The survival time after diagnosis was 10 months, during which time the cat underwent tracheostomy, debulking by endotracheal tube, and tracheal stent placement procedures in combination with toceranib phosphate adjuvant chemotherapy.
