ABSTRACT

BACKGROUND: Sleep disorder is a common problem in adults and affects physical and mental health. We investigated factors associated with poor sleep quality in Korean primary care. METHODS: A total of 129 couples (129 husbands and 129 wives) aged 30 to 79 years were included in this study from March, 2009 to February, 2010. The subjects were surveyed using a specific questionnaire. Sleep disorder was defined by a Pittsburgh Sleep Quality Index global score greater than 5 (poor sleepers). The subjects were divided into a group of good sleepers (n = 160) and a group of poor sleepers (n = 98). Socio-demographic and clinical covariates including age, sex, depression, spouse sleep disorder, and spouse depression were reported. RESULTS: Poor sleep quality was present in 38.0% of total subjects. According to chi-square test results, female, patients with depression, and low sleep quality of spouse were significantly associated with sleep disorder. In multivariate logistic regression analysis, depression increased the risk of poor sleep quality (odds ratio [OR], 7.775; 95% confidence interval [CI], 2.555 to 23.661), and non-risky drinking decreased the risk of poor sleep quality (OR, 0.343; 95% CI, 0.128 to 0.924). CONCLUSION: In our study, more than one-third of participants had poor sleep quality. Depression was a strong independent factor associated with sleep problems.

ABSTRACT

INTRODUCTION: Mammalian tooth pulp is densely innervated by sensory nerves that are mostly C fibers and A delta fibers. However, there is evidence suggesting that many unmyelinated axons in the pulp are in fact parent meylinated axons. MATERIALS AND METHODS: The pulp was removed from healthy premolars and 3rd molars extracted from juveniles and adults undergoing orthodontic treatment, and immunohistochemical staining were applied with NPF200 antibodies, which specifically dye myelinated axons. The specimens underwent an electron microscopy examination with diaminobenzidine (DAB) immunostaining after observation and analysis by fluorescence and confocal laser scanning microscopy. RESULTS: The NPF200 immuno-positive axons in the radicular pulp areas were observed as bundles of many nerve fibers. Many small bundles were formed with fewer axons when firing to the coronal pulp areas and then reachrd a different direction. CONCLUSION: Myelinated fibers innervated to the dental pulp maintain their myelins in the radicular portion, but these fibers lost myelins in the coronal portion. Afterthe loss of myelin, the size of the axoplasm also decreased.

ABSTRACT

Odontogenic Myxoma of the jaws is a rare benign tumor derived from embryonic mesenchymal elements of dental anlage. It appears to originate from the dental papilla, follicle or periodontal ligament. Odontogenic Myxoma of the maxilla is less frequent but behaves more aggressively than that of the mandible, because it spreads through the maxillary sinus. Radiographically, the tumors present as unilocular or multilocular radiolucent lesions with well-defined borders with fine, bony trabeculae. On gross examination, the tumor appears as a smooth, glistening, gelatinous, lobulated mass. On microscopic examination, these neoplasms exhibit loose arrangement of stellate-shaped cells. The intercellular substance is a mucinous and homogeneous matrix. We report a case of odontogenic myxoma of the maxilla observed in our clinic with good prognosis after partial maxillectomy.
