The aim of this study was to examine the factors influencing perceived oral health in elderly individuals residing in the community.

We experienced a case of simple pneumonediastinum showing the findings of pleural effusion. Frontal chest radiography showed not only pneumomediastinum but also diffuse haziness with sharp medial margin on left lower lung field, blunting of costophrenic angle, and indistinct contour of diaphragm simulating pleural effusion. CT scan confirmed that these findings arose from the displaced pleura and the associated compression atelectasis by loculated air on the anterior mediastinum.

Milk of calcium located in the breast is typically a benign entity. However, carcinoma may incidentally arise adjacent to or even within milk of calcium. Consequently, the characteristics of all observed calcific particles should be carefully analyzed. In this study, we report a case of carcinoma presented as malignant microcalcifications mixed within milk of calcium in a breast.

Complete testicular feminization syndrome (androgen insensitivity syndrome) is the most common form of male pseudohermaphroditism, transmitted by means of maternal X-linked recessive gene. This syndrome is marked by unique combination; Normal female phenotype, normal male karyotype, 46,XY, normal or slightly elevated male blood testosterone levels and a high LH. Clinically, the diagnosis should be considered in a female with inguinal hernias, a patient with primary amenorrhea and absent uterus. we present a case testicular feminization syndrome with blindly ended vagina and inguinal masses with a brief review of literatures.

OBJECTIVES: The aims of this study were to find and compare the effect of directional (DIR) processing of two different hearing aids via both subjective and objective methods, to determine the association between the results of the subjective and objective evaluations, and to find out individual predictive factors influencing the DIR benefit. METHODS: Twenty-six hearing aid users fitted unilaterally with each two different experimental hearing aid performed modified Korean Hearing in Noise Test (K-HINT) in three DIR conditions; omnidirectional (OMNI) mode, OMNI plus noise reduction feature, fixed DIR mode. In order to determine benefits from DIR benefit within a hearing aid and compare performance of the DIR processing between hearing aids, a subjective questionnaire was administrated on speech quality (SQ) and discomfort in noise (DN) domain. Correlation analysis of factors influencing DIR benefit was accomplished. RESULTS: Benefits from switching OMNI mode to DIR mode within both hearing aids in K-HINT were about 2.8 (standard deviation, 3.5) and 2.1 dB SNR (signal to ratio; SD, 2.5), but significant difference in K-HINT results between OMNI and OMNI plus noise reduction algorithm was not shown. The subjective evaluation resulted in the better SQ and DN scores in DIR mode than those in OMNI mode. However, the difference of scores on both SQ and DN between the two hearing aids with DIR mode was not statistically significant. Any individual factors did not significantly affect subjective and objective DIR benefits. CONCLUSION: DIR benefit was found not only in the objective measurement performed in the laboratory but also in the subjective questionnaires, but the subjective results was failed to have significant correlation with the DIR benefit obtained in the K-HINT. Factors influencing individual variation in perceptual DIR benefit were still hard to explain.

OBJECTIVE: Self-expanding stents are increasingly used for the treatment of complex intracranial aneurysms. The purpose of this study was to evaluate the usefulness and safety of a self-expanding nitinol stent (Enterprise) in the treatment of wide-necked intracranial aneurysms. METHODS: This was a retrospective study of 39 patients with 40 wide-necked intracranial aneurysms who were enrolled in a single-center registry of patients treated with the Enterprise between June 2009 and December 2011. Thirty patients were asymptomatic, four had cerebrovascular accident sequelae, and five had suffered subarachnoid hemorrhage. One aneurysm had reopened after prior coil embolization, while 39 had not been treated. Clinical charts, procedural data, and angiographic results, including both immediate post-procedural angiograms and follow-up imaging, were reviewed. RESULTS: The mean neck size of the aneurysms was 5.58 mm (range 3-15.1 mm). Embolization was successful in all patients. There were five procedure-related events. There were no fatalities, but one procedure-related morbidity was noted. The immediate angiographic results included eight complete occlusions (20%), six remnant necks (15%), and 26 remnant sacs (65%). At angiographic follow-up (mean: 11.3 months), out of 18 of the aneurysms treated with stent-assisted coiling, there were 13 (72.2%) complete occlusions, four (22.2%) remnant necks, and one recanalization (5.6%). CONCLUSION: Stent-assisted coiling using the Enterprise is effective for the treatment of wide-necked intracranial aneurysms. Further angiographic and clinical follow-up investigation will be needed for evaluation of the long-term outcomes.

Desmoid fibromatosis is a locally aggressive myofibroblastic neoplasm. In this study, we report a case of desmoid fibromatosis in the paraspinal muscle that was misdiagnosed as intramuscular schwannoma through incisional biopsy at another hospital. We performed total excision of the mass lesion with a clear margin. We found that for an accurate diagnosis, magnetic resonance imaging, incisional biopsy and excisional biopsy were required.

Inflammatory pseudotumor, originally described in the lung, is a relatively rare tumor-like lesion that occurs in various organs and tissues. It is usually well demarcated from the surrounding tissue, however it can be unfortunately resected as a malignant tumor. A few inflammtory pseudotumor in the kidney have been reported in English literature, but there have been no reports in Korea. We report a case with inflammatory pseudotumor of the kidney. A 48 year old woman had an intermittent flank pain on the right side. An ultrasonographic study suggested a renal cell carcinoma and a nephrectomy was done. Grossly, there were two separate masses with a well demarcated yellowish appearance, measuring 2.3 cm and 1.3 cm in diameter, respectively. Histologically, they were composed of smooth muscle actin positive spindle cells and a large number of foamy histiocytes, lymphocytes, and plasma cells in the fibrotic backgound.
