Round atelectasis is an uncommon benign pulmonary condition not relevant to neoplastic or inflammatory lung disease, usually presenting as a peripheral parenchymal round mass density on a chest roentgenogram. Recently, authors experienced one patient with this disease entity associated with spontaneous pneumothorax who was treated surgically with a successful outcome. The case is thought to be the first documented report of round atelectasis in Korea.

Background: Cytological examination of pleural effusions is very important in the diagnosis of malignant lesions. Thoracentesis is the first investigation to be performed in a patient with pleural effusion. In this study, we aimed to compare traditional with cell block methods for diagnosis of lung disease accompanied by pleural effusion. Materials and Methods: A total of 194 patients with exudative pleural effusions were included. Ten mililiters of fresh pleural fluid were obtained by thoracentesis from all patients in the initial evaluation. The samples gathered were divided to two equal parts, one for conventional cytological analysis and the other for analysis with the cell block technique. In cytology, using conventional diagnostic criteria cases were divided into 3 categories, benign, malignant and undetermined. The cell block sections were evaluated for the presence of single tumor cells, papillary or acinar patterns and staining with mucicarmine. In the cell block examination, in cases with sufficient cell counts histopathological diagnosis was performed. Results: Of the total undergoing conventional cytological analyses, 154 (79.4%)were reported as benign, 33 (17%) as malignant and 7 (3.6%) as suspicious of malignancy. With the cell block method the results were 147 (75.8%) benign, 12 (6.2%) metastatic, 4 (2.1%) squamous cell carcinoma, 18 (9.3%) adenocarcinoma, 5 (2.6%) large cell carcinoma, 2 (1%) mesothelioma, 3 (1.5%) small cell carcinoma, and 3 (1.5%) lymphoma. Conclusions: Our study confirmed that the cell block method increases the diagnostic yield with exudative pleural effusions accompanying lung cancer.

Purpose: Remnant gastric cancer (RGC) are generally detected at advanced stages or infiltration of adjacent organs. We retrospectively reviewed the surgical outcomes and clinicopathologic results of remnant gastric cancers that have operated during fourteen years in one institution of Korea. Materials and Methods: 34 patients who were diagnosed with RGC at Ajou University Hospital from April 1995 to October 2009 were enrolled. We analyzed the features of previous operation, and according to these results, surgical outcomes and clinicopathologic results for RGC were analyzed. Results: Of 34 patients, 20 patients had previously undergone distal gastrectomy for malignant disease, and 14 patients for benign disease. The period between previous operation and surgery for RGC in the patients underwent operation for malignant disease was shorter than that in benign patients (P<0.001). In surgical field, 31 patients (91.0%) were resected and curative resection was possible in 23 patients (67.6%). When 31 patients who underwent resection for RGC were divided into previous malignant and benign disease, there was no significantly different in terms of surgical outcomes and pathologic findings between two groups. Meanwhile, the patients who recently (after 2005) underwent surgery for RGC showed less advanced stage compared with the patients who underwent surgery before 2004. Conclusions: Resection was possible in the higher proportion (91.0%) of patients diagnosed with RGC compared with previous reports. The cause of previous operation did not effect on the surgical outcomes for surgery of RGC. Recent trend of RGC is to increase the proportion of early stage gastric cancer. Therefore, surgeons should consider curatively surgical resection for RGC the regardless of pattern of previous operation.

Benign prostatic hyperplasia (BPH) is the most common prostate disease in middle aged and elderly men. Therefore, identifying risk factors for BPH is crucial for understanding the etiology and for undertaking interventions or targeting strategies. The survey was carried out in two steps: first, pilot study was conducted prior to the main study in order to estimate baseline characteristics. Second, main study investigated prevalence and risk factors of BPH by clinical diagnostic tests and questionnaire. A total of 641 male aged 50-79 years participated in this community-based cross-sectional study. Using 24 hour recall of food consumption, we found that animal fat intakes increased the risk of BPH with adjusted for age, chronic bronchitis, PSA level, drinking frequency, and excercise frequency (odds ratio 1.84,95% confidence interval 1.10-3.06) . Although BPH has been considered as unavoidable disease with advancing age, if these dietary risk factors are clearly identified, it can be prevented effectively by laying special emphasis on those at risk.

During a 9-year period(March 1985 to February 1994), 111 consecutive total thyroidectomies and modified or radical neck dissections were performed at 81. Vincent Hospital, Catholic University Medical College, for benign and malignant disease. There were three permanent complications, persistent hypoparathyroidism, in total thyroidectomies. Overall complications were observed 20(62.5%) in benign diseases, 47(59.5%) in malignancy. In benign and malignant thyroid diseases. the complications were transient hypoparathyroidisms (28.8%), transient hoarsenesses(21.6%), wound infections (3.6%), bleedings(3.6%), and permanent hypoparathyroidisms(2.7%). Our experience suggests that the morbidity of total thyroidectomy relates primarily to the extracapsular extension, necessitating en bloc exision accompanied by additional lymph node dissection. The low incidence of permanent complications in thyroid disease suggests the feasibility of total thyroidectomy as the operation of choice when surgeons are familiar with the technique and indications.

We report a case with dysphagia for solids. A 51-year-old man with benign esophageal stricture was transferred for endoscopic treatment. He had lye ingestion history at 9 years old and underwent esophagectomy with right colonic interposition for the treatment of the benign esophageal stricture. But his symptom was acting up 2 years ago and lasted afterward even though he had underwent endoscopic treatments for dysphagia several times, including balloon dilation and stent insertion. He had polypoid enhancing wall thickening around anastomosis site of stomach with perigastric soft tissue density and suspicious nodular extension to omentum on the small bowel computed tomography. So he had a surgical resection of small bowel and jejunojejunostomy, and the pathological result was adenocarcinoma, intestinal type with soft tissue infiltration. Later he underwent total gastrectomy with segmental resection of interpositional colon and segmental resection of duodenum and ileo-colic anastomosis revision. And recently he has been on chemotherapy.

Acquired esophagobronchial fistula is relatively rare disease. Its causes are malignancy of esophagus or bronchus, infection, trauma, and diverticulum of esophagus. Malignant esophagobronchial fistula is more frequent than benign origin. The patient was 21-year-old female and had typical Onos sign. On esophagogram, fistulous tract was identified between esophagus and left lower lobe bronchus. The cause was nonspecific inflammation of mediastinum. The fistulous tract was resected and reinforced by mediastinal pleura. Postoperative course was uneventful.

Arrhythmias in the neonatal period are not uncommon, and may occur in neonates with a normal heart or in those with structural heart disease. Neonatal arrhythmias are classified as either benign or nonbenign. Benign arrhythmias include sinus arrhythmia, premature atrial contraction, premature ventricular contraction, and junctional rhythm; these arrhythmias have no clinical significance and do not need therapy. Supraventricular tachycardia, ventricular tachycardia, atrioventricular conduction abnormalities, and genetic arrhythmia such as congenital long-QT syndrome are classified as nonbenign arrhythmias. Although most neonatal arrhythmias are asymptomatic and rarely life-threatening, the prognosis depends on the early recognition and proper management of the condition in some serious cases. Precise diagnosis with risk stratification of patients with nonbenign neonatal arrhythmia is needed to reduce morbidity and mortality. In this article, I review the current understanding of the common clinical presentation, etiology, natural history, and management of neonatal arrhythmias in the absence of an underlying congenital heart disease.

Aircraft accidents caused by dizziness of aviation workers are so common that they account for 5% to 10% of the total, and in most cases, have fatal consequences. Therefore, it is essential to diagnose and treat the dizziness of aviation workers properly. Common diseases caused by abnormal vestibular function include benign paroxysmal positional vertigo, Meniere's disease, and vestibular neuritis. In this paper, we first proposed an overview of these diseases' pathophysiology, diagnosis, and treatment. Also, we evaluated the importance of these diseases in aerospace medicine and presented aerospace medical dispositions for aviation medical examiners.
