Purpose: The study aims to evaluate the effects of Tai Chi applied cardiac rehabilitation program (TCCRP) on cardiovascular risks, recurrence risk in ten years, and cardiac specific quality of life in individuals with coronary artery disease. Methods: The sample was comprised of individuals diagnosed with coronary artery disease within six months of the study who were referred by their primary physicians to participate in the TCCRP. The design was a pretest/posttest with non-equivalent groups with 30 in TCCRP program and 33 wait-listed comparison group. Results: The average age of all participants was sixty seven years. At the completion of the TCCRP, the Tai Chi group showed significant reduction in their ten year recurrent risk for coronary artery disease measured by Framingham's algorithm. The quality of life for the experimental group was reported as significantly higher than the comparison group, especially the area of general symptom. Conclusion: The outpatient cardiac rehabilitation with Tai Chi was applied effectively and safely without any complication to individuals with coronary artery disease. Tai Chi can be useful as an alternative exercise for cardiac rehabilitation program which may provide more access to individuals for cardiovascular risk management in the community settings.

The mediastinum is the most prevalent site of extragonadal teratomas. Patients with mediastinal mature teratomas are usually young adults, and the condition does not show significant sexual differences. Mediastinal teratomas are mostly located in the anterior mediastinum. Patients are usually asymptomatic, although they can have several complications when the teratomas become large or rupture. Most mediastinal teratomas can be diagnosed using CT. Diagnosing ruptured or malignant teratomas is challenging because of their atypical clinical and radiological presentations. In this article, we describe various manifestations of mediastinal teratomas, with an emphasis on radiologic features.

Objective This study aimed to investigate the clinicopathologic risk factors for type-specific persistence of high-risk human papillomavirus (hrHPV) and residual/recurrent cervical intraepithelial neoplasia (CIN) after surgical treatment. Methods Patients with CIN-2/3 who underwent conization or loop electrosurgical excision procedure (LEEP) at Korea University Hospital were enrolled. All patients underwent hrHPV testing and genotyping before conization or LEEP followed by both hrHPV genotyping and cytology. The significance of associations between patient characteristics and persistence of infection were assessed by multivariate logistic regression analyses. Results Among 398 women with pathologically confirmed CIN-2/3, 154 (38.7%) patients showed hrHPV persistence after surgical treatment. In multivariate analysis, high preoperative hrHPV load (P

A uterocutaneous fistula is rarely reported clinical condition after uterine procedures. Many diagnostic and management strategies are being suggested. In this case report, uterocutaneous fistula after pelviscopic myomectomy was diagnosed simply with hystero-salpingo contrast sonography and managed by surgical tract excision without hysterectomy and uterine wall dehiscence repair combined with medical treatment using gonadotropin-releasing hormone agonist succeeded to preserve fertility in young woman.

ObjectiveThe aim of this study was to compare and determine the feasibility, surgical outcomes, learning curves of robotic radical hysterectomy with lymph node dissection (RRHND) to conventional laparoscopic radical hysterectomy with lymph node dissection (LRHND) performed by a single surgeon, in patients with cervical cancer.MethodsBetween April 2009 and March 2013, 22 patients underwent LRHND and 19 patients underwent RRHND. Variables such as age, body mass index, International Federation of Gynecology and Obstetrics stage, histological results, number of dissected lymph nodes, operative time, estimated blood loss, days of hospitalization and complications were reviewed. Learning curves of operation time was obtained using cumulative sum (CUSUM) method.ResultsBoth groups showed similar patient and tumor characteristics. In surgical outcome analysis, RRHND (51.8±10.4 minutes) showed longer preparing time than LRHND (42.5±14.1 minutes). In the LRHND group, 8 patients experienced postoperative complications (5 void difficulty, 1 postoperative bleeding, 1 right basal ganglia infarction, 1 fever). On the other hand, in the RRHND group, 4 patients experienced a postoperative complication (2 bleeding, 1 peritonitis, 1 dehiscence of trocar site). Using CUSUM method, the learning curves were obtained by plotting the cumulative sequential differences between each data point and the average operation time, and showed two distinct phases in both type of operations.ConclusionRRHND would be appropriate surgical approach in patients with cervical cancer with favorable outcome of less voiding difficulty. A minimum of 13 cases of robotic radical hysterectomies are required to achieve surgical improvement in the treatment of cervical cancer.

Background: There have been no studies of airway management strategies for difficult intubation and cannot intubate, cannot ventilate (CICV) situations in Korea. This study was intended to survey devices or methods that Korean anesthesiologists and intensivists prefer in difficult intubation and CICV situations. Methods: A face-to-face questionnaire that consisted of a doctor’s preference, experience and comfort level for alternative airway management devices was presented to anesthesiologists and intensivists at study meetings and conferences from October 2014 to December 2014. Results: We received 218 completed questionnaires. In regards to difficult intubation, the order of preferred alternative airway devices was a videolaryngoscope (51.8%), an optical stylet (22.9%), an intubating laryngeal mask airway (11.5%), and a fiber-optic bronchoscope (10.6%). One hundred forty-two (65.1%) respondents had encountered CICV situations, and most of the cases were identified during elective surgery. In CICV situations, the order of preferred methods of infraglottic airway management was cricothyroidotomy (CT) by intravenous (IV) catheter (57.3%), tracheostomy by a surgeon (18.8%), wire-guided CT (18.8%), CT using a bougie (2.8%), and open surgery CT using a scalpel (2.3%). Ninety-eight (45%) of the 218 respondents were familiar with the American Society of Anesthesiologists’ difficult airway algorithm or Difficult Airway Society algorithm, and only 43 (19.7%) had participated in airway workshops within the past five years. Conclusion: The videolaryngoscope was the most preferred device for difficult airways. In CICV situations, the method of CT via an IV catheter was the most frequently used, followed by wire-guided CT method and tracheostomy by the attending surgeon.

Epithelioid hemangioendothelioma (EHE) is a relatively rare and moderately aggressive type of vascular tumor. We describe a case of EHE that presented in a 24-year-old woman as a palpable nodule in the left cervical area. Radiological examinations and fine-needle aspiration cytology led to a preliminary diagnosis of metastatic lymphadenopathy with an unknown primary site. However, during surgery, we determined that the nodule was an intravascular tumor arising from the left internal jugular vein. The histopathological examination revealed cords of epithelioid endothelial cells distributed in a hyaline stroma, compatible with a diagnosis of EHE.

Background: Surgical enucleation is the treatment of choice for esophageal submucosal tumors (SMTs) with symptomatic, larger, or ill-defined lesions. The enucleation of SMTs has traditionally been performed via thoracotomy. However, minimally invasive approaches have recently been introduced and successfully applied. In this study, we present our experiences with the thoracotomic and thoracoscopic approaches to treating SMTs. Methods: We retrospectively reviewed 53 patients with SMTs who underwent surgical enucleation between August 1996 and July 2013. Demographic and clinical features, tumor-related factors, the surgical approach, and outcomes were analyzed. Results: There were 36 males (67.9%) and 17 females (32.1%); the mean age was 49.2±11.8 years (range, 16 to 79 years). Histology revealed leiomyoma in 51 patients, a gastrointestinal stromal tumor in one patient, and schwannoma in one patient. Eighteen patients (34.0%) were symptomatic. Fourteen patients underwent a planned thoracotomic enucleation. Of the 39 patients for whom a thoracoscopic approach was planned, six patients required conversion to thoracotomy because of overly small tumors or poor visualization in five patients and accidental mucosal injury in one patient. No mortality or major postoperative complications occurred. Compared to thoracotomy, the thoracoscopic approach had a slightly shorter operation time, but this difference was not statistically significant (120.0±45.6 minutes vs. 161.5±71.1 minutes, p=0.08). A significant difference was found in the length of the hospital stay (9.0±3.2 days vs. 16.5±5.4 days, p＜0.001). Conclusion: The thoracoscopic enucleation of submucosal esophageal tumors is safe and is associated with a shorter length of hospital stay compared to thoracotomic approaches.

Pyothorax-associated lymphoma is a relatively rare type of lymphoma that occurs in patients who have long histories of tuberculous pleuritis or induced pneumothorax. It is a type of non-Hodgkin’s lymphoma of mainly the B-cell phenotype and is strongly associated with Epstein−Barr virus infection. A majority of these cases have been reported in Japan, although some cases have occurred in Western countries. Here, we describe a case of pyothorax- associated lymphoma in a patient with a 30-year history of chronic tuberculous empyema. The patient underwent decortication under the impression of chronic empyema with fistula. The histopathologic diagnosis was a diffuse large B-cell lymphoma associated chronic inflammation.
