PURPOSE: The purpose of this study was to construct and test a structural equation model to investigate the risk factors of metabolic syndrome in rural women. METHODS: The raw data in this study was collected from the Korean Genome and Epidemiology Study supervised by the Korea Centers for Disease Control and Prevention from 2005 to 2010. The data included physical examinations and surveys of 1,125 women, who resided in three rural areas of South Korea. The structural model in this study was composed of five latent variables: depression, stress, social support, health behavior, and metabolic syndrome. The structural equation model was used to assess the relationships among the variables. RESULTS: The results of the study showed that depression and stress had direct effects on metabolic syndrome. Social support had a direct effect on health behavior and metabolic syndrome. Also, health behavior had a direct effect on metabolic syndrome. CONCLUSION: This study may serve as a guideline for interventions and strategies used to reduce metabolic syndrome in rural women.

Sarcoma of the uterus is very rare malignant tumor arising from the muscle or connective tissue, and there are only a few cases reported in Korea. We have experienced 16 cases of uterine sarcomas for 10 years from 1986 to 1995. The results are as follows: 1. The incidence of uterine sarcomas in uterine leiomyomas was estimated to 0.69%. 2. The pathologic types were 5 cases(31.3%) of leiomyosarcoma, 3 cases(18.8%) of endometrial stromal sarcoma, 6 cases(37.5%) of malignant mixed Mllerian tumor 2 cases(12.5%) of rhabdomyosarcoma in order. 3. The mean age was 46.4 years. 4. Seven(58.7%) were stage I, 2(16.7%) were stage III, and 3(25.6%) were stage IV. 4. The chief complaints on admission were abdominal mass(50%), abnormal bleeding(25%), and pelvic or abdominal pain(25%). 5. The estimated median survival was 43 months, and there was no correlation between survival and number of mitotic figure per 10 high power fields, stages, or radiation therapy.

An angiomatous polyp originates from a sinochoanal polyp, and may be confused with a vascular neoplasm. Compromise of their vascular supply may occasionally lead to infarction, resulting in clinical, radiological and pathological features that simulate a neoplastic process. Recently, we experienced a case of angiomatous nasal polyp that eroded the anterior wall of maxilla at the time of its presentation in a 15-year-old boy. Angiomatous nasal polyps are poorly documented in clinical literature. Although entirely benign, they may simulate neoplastic processes. Thus, awareness of their existence is of considerable importance.

OBJECTIVE: To compare the clinical outcomes of patients with vitrified-thawed embryos transferred using either the 0.25 mL straw method and the pull and cut straw (PNC) method. To evaluate the clinical outcomes of patients with transferred embryos that underwent assisted hatching at the cleaved embryo (day 3) or the blastocyst (day 5) stage. METHODS: The study population consisted of women who underwent vitrified-warmed embryo transfer between May 2000 and December 2011 and assisted hatching was performed after warming of embryos. Cycles of thawing between assisted hatching treated and non treated groups were compared for survival and pregnancy rates. RESULTS: The PNC vitrification method improved survival and pregnancy rates in partial lysed embryos. While assisted hatching did not affect the developmental and clinical pregnancy rates of the vitrified-warmed blastocyst group, it did increase the pregnancy rate of poor quality vitrified-warmed cleaved embryos. CONCLUSION: These results suggest that PNC may increase the number of clinical pregnancies via the vitrification of both cleaved embryos and blastocysts. In addition, selective assisted hatching treatment of embryos that show a poor prognosis after warming may increase the rate of clinical pregnancy.

BACKGROUND AND OBJECTIVES: Clinical differentiation of peritonsillar abscess (PTA) from peritonsillar cellulitis is sometimes difficult and physicians often rely on blind needle aspiration to locate abscess formation. According to previous studies, intraoral ultrasound is a useful, simple, and noninvasive technique that candifferentiate PTA from cellulitis in clinically equivocal cases, although it may cause some discomfort. The objective of this study was to establish a neck ultrasonographic technique that candifferentiate PTA from cellulitis in borderline cases and thereby to avoid unnecessary needle aspiraton. SUBJECTS AND METHOD: The study population included 44 patients (32 males and 12 females; age range 13 to 59 years) with clinically suspected PTA. These patientsunderwent neck ultrasonography examination before needle aspiration of abscess. RESULTS: On the basis of neck ultrasonography, 38 patients were considered as PTA and 6 as cellulitis. Neck ultrasonography was able to detect peritonsillar abscess in 94.7 per cent of the cases (sensitivity). The specificity of the test was 83.3 per cent, and accuracy was 79.1 per cent. CONCLUSION: Neck ultrasonography is a useful, simple, well-tolerated non-invasive technique that can be used to differentiate PTA from cellulitis in clinically equivocal cases.

We report a recently encountered case of angioleiomyoma in oropharynx. The patient was a 26-year-old woman. The main symptoms were feeling of narrowing down of the pharynx and difficulty in breathing in the left supine position. Laryngoscopy revealed a 3.5cm-sized, spherical mass with a smooth surface, originating in the right oropharyngeal wall. The tumor was successfully removed using suspension microlaryngoscopy under general anesthesia. Histopathologically, it was well circumscribed and composed of proliferating smooth muscle fibers and dilated blood vessels. The tumor is a benign nature and recurrence is rare. Complete removal is the treatment of choice with care taken to avoid profuse bleeding.

Self-induced pneumoparotitis is a rare cause of swelling of the parotid gland. It has been reported to be a result of psychosomatic disorder, unintentional habit, and it is sometimes self-induced by patients to achieve secondary gain. We report a case of a 18-year-old man who had a self-induced pneumoparotitis complicated by recurrent parotitis, subcutaneous emphysema and pneumomediastinum. With repeated behavior of insufflation, parotid acini may rupture and air may extend into the retropharyngeal space, causing pneumomediastinum or pneumothorax. In self-induced cases, treatment should necessitate psychologic therapy for behavior modification.

Myxoma is a relatively rare tumor of mesenchymal origin that can be found in numerous sites throughout the body including heart, skin, and subcutaneous tissue along with various sites in the head and neck. It is presumed to be originated from dental malformation or missing teeth, but occasionally myxoma without dental abnormalities is found giving arguments for its embryogenesis. Myxoma in the head and neck is usually managed by radical operation in order to prevent the possible recurrence. A case of recurrent myxoma of maxilla is described, which was treated with en-bloc removal via lateral rhinotomy incision. The purpose of this article is to present a case of myxoma of maxilla with a review of the literature and is to give a special emphasis on the proper modalities of treatment which minimizes recurrence and functional deficit.

Objectives: The purpose of this study was to evaluate risk factors and symptoms in cemento-osseous dysplasia (COD) patients. Materials and Methods: In this study, 62 patients who were diagnosed histologically with COD were investigated from 2010 to 2020 at the author’s institution. We compared clinical and radiological characteristics of symptomatic and asymptomatic patients. The factors were sex, age, lesion size, site, radiologic stage of lesion, apical involvement, sign of infection, and history of tooth extraction. Statistical analysis was performed using Fisher’s exact test and the chi-square test. Results: COD was more prevalent in female patients. With the exception of three cases, all were focal COD. The majority of patients presented with symptoms when the lesion was smaller than 1.5 cm in size. Symptoms were observed when the apex of the tooth was included in the lesion or there was a local infection around the lesion. The history of tooth extraction and previous endodontic treatment were evaluated, and history was not a significant predictor for the onset of symptoms. Conclusion In this study, risk factors associated with symptomatic patients were size of lesion, apical involvement, and local infection.
