Background: this study was designed to estimate whether specific risk factors could increase the postoperative complication rate of pneumonectomy for chronic complicated inf-lammatory lung disease. Material and Method: Eighty-five patients underwent pneumon-ectomy for chronic complicated inflammatory lung disease(tuberculosis, 67 ; bronchiecasis 11; aspergio- losis, 4; others, 3) between January 1991 and August 1998. We performed a univariated statistical analysis to identify preoperative and intraoperative risk factors associated with postoperative complications, Result: There was no operative mortality. There were a total of 18 postoperative complications(22.2%) Bronchopleural fistula(BPF) and empyema occurred in 5(5.9%) and 2(2.4%) respectively. General complication rate was significantly higher in patients with right-sided pneumonectomy(p=.029) extrapleural pneu-monectomy(p=.009) and intraoperative pleural spillage due to cavity or lesion perforation (p=.004). The prevalence of BPF and empyema was higher in patients with right sided pneumonectomy(p=.007) extrapleural pneumonectomy(p=.015) and intraoperative pl- eural spillage due to cavity or lesion perforation(p=.003) which is as the same results as gen-eral complication rate. Conclusion: The postoperative complication rate of pneumone-ctomy for chronic complicated lung disease is accptably low. But it is increase in patients with right sided pneumonectomy extrapleural pneumonectomy and intraoperative pleural spillage due to cavity or lesion perforation. therefore more careful and meticulous intra-operatve management are needed in right sided extrapleural pneumonectomy without intra- pleural spillage.

The term chronic lateral ankle instability (CLAI) embraces a spectrum of conditions that involve functional and mechanical instability, both in athletes and lower-demand patients. The hallmarks of CLAI are recurrent sprains, persistent pain, and repeated episodes of the ankle giving way. CLAI is the main complication of acute ankle sprains, which can cause discomfort in daily and sports activity. Approximately 10% to 30% of patients with acute ligament ruptures will develop chronic instability over the course of a year from the index injury. An accurate diagnostic approach and successful treatment plan should be established based on a comprehensive understanding of the concept of functional and mechanical instability. Unfortunately, the optimal modality for the management of CLAI is unclear. Even after conservative treatment or surgical intervention, it could result in degenerative changes to the ankle joint in the long term. Thus far, the incidence of ligamentous posttraumatic ankle osteoarthritis was reported to be 13% to 78%. The mean latency time between injury and osteoarthritis was at least 10 to 34.3 years. CLAI is an important pathological condition that can cause discomfort or dysfunction in daily activity in the short term, resulting in joint destruction in the long term. Therefore, it is important to understand the various complications that can occur when CLAI is not treated properly.

Technique of epidural analgesia is generally regarded a safe procedures which is widely applied in postoperative and chronic pain control. Incidence of neurologic complications following epidural analgesia are rare; however, increasing number of published reports describing transient or permanent neurologic complications following such procedures have been appearing more frequently. We report two cases of neurologic complications following epidural analgesia as we believe it is important to draw the attention of other anesthesiologist to the possibility of existence of other complications of significant medicolegal consequences.

Lung transplantation (LT) is now considered as an effective treatment option for end-stage lung diseases that improves the short and long-term survival rates and quality of life. As increasingly many LT procedures are being performed, the medical complications of LT are also increasing in frequency and emerging as a very important issue for transplant clinicians. Although chronic lung allograft dysfunction and infection are major causes of death after LT, many medical complications, several of which result from immunosuppressive treatment, contribute to increased mortality and morbidity. This article reviews the most frequent and important medical complications of LT, accompanied by a review of the literature and studies from South Korea, including lung allograft rejection, infection, and non-allograft organ systemic complications.

Burr hole drainage has been widely used to treat chronic subdural hematomas (SDH), and most of them are easily treated by simple trephination and drainage. However, various complications, such as, hematoma recurrence, infection, seizure, cerebral edema, tension pneumocephalus and failure of the brain to expand due to cerebro-cranial disproportion may develop after chronic SDH drainage. Among them, intracerebral hemorrhage after evacuation of a recurrent chronic SDH is very rare. Here, we report a fatal case of delayed intracerebral hemorrhage caused by coagulopathy following evacuation of a chronic SDH. Possible pathogenic mechanisms of this unfavorable complication are discussed and a review of pertinent literature is included.

The shoulder is a complex area which makes it vulnerable to painful pathologic processes. Chronic shoulder pain has become more common recently due to increased use of computers and a ,generally more sedentary life style among most people . Trigger point injection and neural blockade are useful for the management of chronic shoulder pain which has not improved with conservative treatment. Published articles concerning trigger point injection or neural blockade for chronic shoulder pain were reviewed to evaluate promising methods. If we are careful to remain aware of the details and complications in addition to adhering to effective treatments, these should be good armamentarium for doctors enthusiastic about the management of chronic shoulder pain.

Background: Conservative treatment is performed for isolated anterior wall of the maxillary sinus fractures, in many cases when the fracture is clinically not severe and asymptomatic. Despite the absence of symptoms, complications such as sinusitis, rhinitis, and chronic purulent secretion may develop; therefore, successful reduction is required. We attempted to reduce the risk of complications using an alternative technique: reduction of the fracture with two urinary balloon catheters inserted through the maxillary ostium and fixation using fibrin glue, which minimizes the damage to the bony fragments and sinus mucosa. Methods: In this study, 38 patients who were diagnosed with an isolated anterior wall of the maxillary sinus fracture at our hospital between January 2014 and January 2017 were enrolled. The fracture site was exposed via the Caldwell-Luc approach followed by reduction through the insertion of two urinary balloon catheters using a nasal endoscope and fixation with fibrin glue. The sex, cause of fracture, physical examination, and presence of complications were examined and patient's medical records and facial bone computed tomography scans were analyzed. Results: Radiological evaluation showed that there was no evidence of collapsed reduction fragments. Although some patients had remaining symptoms of hypoesthesia (15%; 3 patients), there were no complications such as infection, rhinitis, sinusitis, and chronic purulent secretion at the surgical site. Conclusion: In this study, we present an alternative surgical technique using two urinary balloon catheters and fibrin glue for the successful reconstruction of an isolated anterior wall of the maxillary sinus fracture. This technique enables precise restoration with a reduced risk of complications.

Chronic diseases including hypertension and its complications are major sources causing the national medical expenditures to increase. We aim to predict the risk of hypertension complications for hypertension patients, using the sample national healthcare database established by Korean National Health Insurance Corporation. We apply classification techniques, such as logistic regression, linear discriminant analysis, and classification and regression tree to predict the hypertension complication onset event for each patient. The performance of these three methods is compared in terms of accuracy, sensitivity and specificity. The result shows that these methods seem to perform similarly although the logistic regression performs marginally better than the others.
