Hemangioma of the heart, presenting as a primary cardiac tumor is extremely rare; it accounts for approximately 2% of all primary resected heart tumors. In our patient, the tumor was located in the orifice of the right lower pulmonary vein. Few cases of cardiac hemangiomas have been reported to arise from the left atrial (LA) wall. Left atrial hemangiomas, especially those attached to the LA wall, may be erroneously diagnosed as myxomas. Cardiac hemangioma is a rare disease; furthermore, a tumor arising from the LA wall and misconceived as a myxoma is extremely rare. We removed a mass misdiagnosed as a myxoma; it was pathologically confirmed to be a cardiac capillary hemangioma. Therefore, we report a rare case of a cardiac hemangioma misconceived as a myxoma; the tumor was removed successfully.
Synovial sarcoma is a malignant soft tissue tumor that most commonly occurs in the extremities of young and middle-aged adults, in the vicinity of large joints. Although synovial sarcoma is frequently associated with joints, it may arise in unexpected sites, such as the mediastinum, heart, lung, pleura, or chest wall. Primary synovial sarcoma of the pleura is rare. To date, nearly 36 cases of primary synovial sarcoma of the pleura have been reported since Gaertner et al. published the first case in 1996. The oncologic characteristics, treatment, and prognosis for pleural synovial sarcomas are not well defined because of a paucity of data. However, a multimodal approach, including surgical resection, chemotherapy, and radiotherapy, has generally been suggested. We report the outcome of one patient with primary pleural synovial sarcoma treated with radical resection and adjuvant treatment.
The purpose of this study was to investigate the influence of recycled aggregates powder (RP) contents on recycled aggregates (RA) using fly-ash (FA) mortar in a condition of zero cement targeting earth filling materials, and the results can be summarized as follows. First, there was a tendency that as RP contents increased, W/B and air contents increased also. In the case of compressive strength, the strength was hardly developed at the early age, which was prior to 14 days; however, with the starting point of 14 days of age, strength of around 1.5 ∼2.0 MPa was developed when it arrived at 28 days. At a curing temperature of 20℃, the more RP contents increased, the more the compressive strength increased in comparison with FA 100% at all levels except RP 100 %, showing the highest compressive strength at RP 25 %. At a curing temperature of 35℃, the temperature-dependence appeared to be large, as the RP contents were decreased compared to the curing temperature of 20℃. In addition, based on SEM analysis, this study was able to confirm that a pozzolanic reaction formed by an alkali stimulus of RA with the lapse of certain days even in 100 percent FA, causing the densification of tissues, and with RP 25%, hydrate was created the most densely by the hydration of unhydrated cement particles and pozzolanic reaction of FA.
BackgroundTreatment for patent ductus arteriosus (PDA) in premature infants can consist of medical or surgical approaches. The appropriate therapeutic regimen remains contentious. This study evaluated the role of surgery in improving the survival of premature neonates weighing less than 1,500 g with PDA.Materials and MethodsFrom January 2008 to June 2011, 68 patients weighing less than 1,500 g with PDA were enrolled. The patients were divided into three groups: a group managed only by medical treatment (group I), a group requiring surgery after medical treatment (group II), and a group requiring primary surgical treatment (group III).ResultsThe rate of conversion to surgical methods due to failed medical treatment was 67.6% (25/37) in the patients with large PDA (≥2 mm in diameter). The number of patients who could be managed with medical treatment was nine which was only 20.5% (9/44) of the patients with large PDA. There was no surgery-related mortality. Group III displayed a statistically significantly low rate of development of bronchopulmonary dysplasia (BPD) (p=0.008). The mechanical ventilation time was significantly longer in group II (p=0.002).ConclusionMedical treatment has a high failure rate in infants weighing less than 1,500 g with PDA exceeding 2.0 mm. Surgical closure following medical treatment requires a longer mechanical ventilation time and increases the incidence of BPD. Primary surgical closure of PDA exceeding 2.0 mm in the infants weighing less than 1,500 g should be considered to reduce mortality and long-term morbidity events including BPD.
Objective: There are still a limited number of studies assessing the prevalence of metabolic syndrome in the community. The aim of this study is to investigate the prevalence and gender-related characteristics of metabolic syndrome in Korean community. Methods: A total of 417 community subjects (mean age was 60.7±13.6 years, 35.3% were men) who attended the routine check-up were analyzed. National Cholesterol Education Program-Adult Treatment Panel (NCEP-ATP) III clinical guideline was used to define metabolic syndrome. Results: Metabolic syndrome was diagnosed in 38.1% of study subjects. The prevalence of metabolic syndrome was not different between men and women (men 39.0% vs. women 37.5%, p=0.766). The positive association between age and the prevalence of metabolic syndrome was more pronounced in women (χ 2 =17.52, p for trend<0.001) than men (χ 2 =2.38, p for trend=0.123). In young age group (<50 years), the prevalence of metabolic syndrome was higher in men than in women (34.7% vs. 11.7%, p=0.042). This gender difference was not observed in older group (≥50 years). The most prevalent factor of metabolic syndrome was hypertriglyceridemia (49.9%) and hypertension (47.6%) in both genders. Among metabolic syndrome components, central obesity (40.5% vs. 25.2%, p=0.002) and hypertriglyceridemia (54.5% vs. 41.8%, p=0.015) were more prevalent in women than in men, and the prevalence of other components were similar between genders. Conclusions: In the community, metabolic syndrome was highly prevalent in middle-aged and elderly Korean adult. Age related change in the prevalence of metabolic syndrome was gender specific. Age and gender effects should be considered for the effective control of metabolic syndrome in the community.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
