Bilateral pneumothorax in a patient with anaplastic thyroid carcinoma and lung metastasis during lenvatinib therapy: a case report.

The prognosis of anaplastic thyroid carcinoma (ATC) is very poor. In most patients, ATC presents with cervical lymph node metastasis, and more than 40% of patients have distant metastasis at the time of diagnosis. Lenvatinib, a multi-targeted tyrosine kinase inhibitor, is a novel drug that has antitumor effects on radioactive iodine-refractory papillary cancer and anaplastic cancer.

Mild Ischemic Mitral Regurgitation: Is Revascularization Enough for Every Patient?

Background: The progress of mild ischemic mitral regurgitation (MR) after isolated coronary artery bypass is not clear. We aimed to determine the proportion of patients with mild ischemic MR undergoing isolated coronary artery bypass grafting (CABG) presenting with regression of or persistent MR one year after CABG and to identify the significantly different echocardiographic variables between regressing and persistent MR.

Methods: Sixty-three patients with preoperative mild ischemic MR were categorized into an MR- regression or an MR-persistence group one year after isolated CABG.

Primary Pulmonary Chordoid Meningioma.

Primary pulmonary meningioma is a rare disease, and chordoid meningioma is an uncommon variant of meningioma in the central nervous system (CNS) with a high recurrence rate. We report a case of primary pulmonary chordoid meningioma that presented as a solitary pulmonary nodule (SPN). The SPN was resected by thoracoscopic wedge resection and was revealed to have characteristics of chordoid meningioma.

Robotic Thyroidectomy: Comparison of a Postauricular Facelift Approach with a Gasless Unilateral Axillary Approach.

Objectives: Robotic thyroidectomy using remote access approaches has gained popularity with patients seeking to avoid neck scarring and enhanced cosmetic satisfaction. The aim of this study was to compare the efficacy and advantages of a postauricular facelift approach vs a gasless unilateral axillary (GUA) approach in robotic thyroidectomy.

Study Design: Case series with chart review.

Synergistic effect between celecoxib and luteolin is dependent on estrogen receptor in human breast cancer cells.

The anti-cancer effects of celecoxib and luteolin are well known. Although our previous study demonstrated that the combination of celecoxib and luteolin synergistically inhibits breast tumor growth compared with each of the treatments alone, we did not uncover the molecular mechanisms of these effects. The aims of our present study were to compare the effects of a celecoxib and luteolin combination treatment in four different human breast cell lines and to determine the mechanisms of action in vitro and in vivo.

Primary Sternal Osteomyelitis Caused by Actinomyces israelii.

Primary sternal osteomyelitis is a rare disease. Common infectious organisms causing primary sternal osteomyelitis include Staphylococcus aureus and Pseudomonas aeruginosa. Actinomyces species are common saprophytes of the oral cavity, but there have been few reports in the literature of primary sternal osteomyelitis caused by Actinomyces species.

Left ventricular pseudoaneurysm after valve replacement.

We present a case of left ventricular pseudoaneurysm, which is a very rare and fatal complication of cardiac procedures such as mitral valve replacement. A 55-year-old woman presented to the Department of Thoracic and Cardiovascular Surgery at Hanyang University Seoul Hospital with chest pain. Ten years prior, the patient had undergone double valve replacement due to aortic regurgitation and mitral steno-insufficiency.

Surgical Ligation on Significant Patent Ductus Arteriosus in Very Low Birth Weight Infants: Comparison between Early and Late Ligations.

Background: We aimed to evaluate the efficacy and safety of early surgical ligation (within 15 days of age) over late surgical ligation (after 15 days of age) by a comparative analysis of very low birth weight (VLBW) infants undergoing surgical correction for symptomatic patent ductus arteriosus (PDA) over the course of 6 years in our hospital.

Methods: We retrospectively reviewed all the medical records in the neonatal intensive care unit at Hanyang University Seoul Hospital, from March 2007 to May 2013, to identify VLBW infants (< 1,500 g) who underwent surgical PDA ligation.

Results: The gestational age (GA) in the late ligation (LL) group was significantly younger than in the early ligation (EL) group (p=0.

Radioactive iodine treatment for node negative papillary thyroid cancer with capsular invasion only: Results of a large retrospective study.

Aim: With thyroid carcinoma the decision to use radioactive iodine (RAI) ablation depends on the risk of poor outcomes. Although extrathyroid extension (ETE) is well known as a risk of poor outcomes for papillary thyroid carcinoma (PTC), the definition of minimal ETE is too broad, as it encompasses both microscopic invasion of the thyroid capsule (capsular invasion [CI]) and macroscopic invasion of the sternothyroid muscle.

Methods: We conducted a retrospective study to analyze the prognostic benefit of RAI ablation according to the presence of CI in a consecutive series of patients with PTC between October 1997 and December 2008.

Antioxidant effect of captopril and enalapril on reactive oxygen species-induced endothelial dysfunction in the rabbit abdominal aorta.

Background: Reactive oxygen species (ROS) are known to be related to cardiovascular diseases. Many studies have demonstrated that angiotensin-converting enzyme inhibitors have beneficial effects against ROS. We investigated the antioxidant effect of captopril and enalapril in nitric oxide mediated vascular endothelium-dependent relaxations.

Silastic molding method for pectus excavatum correction using a polyvinyl alcohol (ivalon) sponge.

Pectus excavatum is rare, but it is the most common type of sternal congenital disorder. There are many surgical methods to correct pectus excavatum such as the Ravitch method, Wada method, Silastic mold method, and the Nuss operation. We report a case of minimal invasive surgery for pectus excavatum using a polyvinyl alcohol sponge.

Emergent surgical intervention for embolization of atrial septal defect closure device.

The percutaneous transcatheter closure of secundum atrial septal defect has recently become an increasingly widespread alternative to surgical closure in many centers. Although immediate, short, and intermediate term results of percutaneous transcatheter septal closure are promising, the procedure is not free from inherent complications that could be lethal. We report a case of device embolization necessitating emergent surgical retrieval.

Congenital cystic adenomatoid malformation with bronchial atresia in elderly patients.

Unlabelled: Congenital cystic adenomatoid malformation (CCAM) is an uncommon, nonhereditary anomaly caused by arrest of lung. Patients with CCAM may present with respiratory distress as newborns, or may remain asymptomatic until later in life. CCAM type I is rarely found in association with bronchial atresia (BA) in adults; we present such a case.

Postinfarct ventricular septal defect after coronary covered stent implantation.

We report a case of a postinfarction ventricular septal defect caused by an acute recurrent occlusion after the implantation of a covered stent, which was performed as a rescue procedure for the ruptured left anterior descending artery during a percutaneous coronary intervention. Although the emergent implantation of a covered stent for the ruptured coronary arteries such as the left main coronary artery or the origins of the left anterior descending artery can be performed during a percutaneous coronary intervention, and a coronary bypass surgery should be considered in order to decrease the risk of complete occlusion, thus providing a superior long term patency.

Omental mesothelial cyst herniated to the thorax through the esophageal hiatus: a case report.

Both mesothelial cyst in the omentum and omental herniation through the esophageal hiatus without abdominal visceral involvement are rare. We report a case of omental mesothelial cyst herniated to the thorax through the esophageal hiatus.

Parosteal lipoma of the rib.

Parosteal lipoma is a rare benign tumor that is composed mainly of benign mature lipocytes, and it has an intimate association with the underlying periosteum of affected bone. Parosteal lipoma involving the rib is quite rare. We believe that only four cases have been previously reported in the English literature.

Diagnosis and prognosis of traumatic pulmonary psuedocysts: a review of 12 cases.

Background: Traumatic pulmonary pseudocysts or post-traumatic pneumatocoeles are a relatively rare-encountered condition occurring after trauma and an even rarer talked about subject. Most resolve within a few weeks, but if complicated by hematoma, may persist for months. This study intends to evaluate the resolution times of traumatic pulmonary pseudocysts and their clinical significance.

Calcifying fibrous pseudotumor of the pleura.

Calcifying fibrous pseudotumor is an uncommon benign lesion that has unique histologic features. We report a case of calcifying fibrous pseudotumor of the pleura occurring in a 31-year-old woman. A computed tomographic scan revealed a pleural mass in the right anterior costophrenic angle.

Telangiectatic pulmonary arteriovenous malformation.

Telangiectatic pulmonary arteriovenous malformation is defined as a pulmonary arteriovenous malformation involving every segmental artery of at least one lobe of the lung. The authors report a case of telangiectatic pulmonary arteriovenous malformation in the left lower lobe of the lung.
