PURPOSE: The purposes of this article are to identify CT findings distinguishing nasal polyps, that are the most common cause of the nasal polypiod lesions, from other nasal cavity masses and to identify differential points between benign and malignant masses of nasal cavity. MATERIALS AND METHODS: We classified 567 cases of pathologically proved nasal cavity masses into 4 different groups on CT according to the sites of origin and surrounding bone changes. RESULT: The nasal polyps were the most common cause of nasal cavity masses(515/567). Group I had a high diagnostic specificity for the nasal polyps (513/515, 99.6%) although inverted papilloma (8/522) and malignant melanoma(1/522) showed similar CT appearances. The representitive nasal mass of Group Ila was the inverted papilloma (15/24, 66.5% of the inverted papilloma). Group III pattern was seen in 3 cases of benign minor salivary gland tumor and 2 cases of pyogenic granuloma. Group IV suggested malignancy and thus was mostly observed in malignant tumors except I case of inverted papilloma and 1 case of granulomatous necrosis. CONCLUSION: The differential diagnosis between nasal polyps and the other nasal cavity masses is possible by characteristic bone changes and their sites of origin revealed on CT. In addition, it is possible to differentiate malignant masses from benign in most cases.

We performed a randomized, prospective study to evaluate the effect of intraoperative, intracameral carbachol or acetylcholine on early postoperative intraocular pressure(IOP) after extracapsular cataract extraction(ECCE) and posterior chamber lens(PCL) implantation. Fifty-six eyes of 56 patients scheduled for routine ECCE and PCL implantation were randomly assigned into three groups: (1)carbachol infusion (19 eyes) (2) acetylcholine infusion (15 eyes) (3)balanced salt solution (BSS) infusion (control, 22 eyes). We compared the preoperative IOP, early postoperative IOP, postoperative 24 hours IOP and postoperative 1 week IOP. In the measurement of early postoperative IOP, IOP was measured at least twice at 3, 6 or 9 hours postoperatively. There was no significant difference in IOP between the three groups preoperatively, at postoperative 3 hours, and 1 week. At postoperative 6 hours, both the carbachol infusion group and acetylcholine infusion group were significantly different from the BSS infusion group. At postoperative 9 and 24 hours, only carbachol infusion group had a significant difference from BSS infusion group in suppression of postoperative IOP increase. Our results suggest that intraoperative, intracameral administration of carbachol or acetylcholine prevents early postoperative IOP increase, and that carbachol has a more lasting effect.

BACKGROUND: Many people experience varying levels of discomfort when confronted with the prospect of dental treatment. Dental treatment can be a traumatic experience, especially for children and adolescents with dental anxiety. In this age group, dental fear causes a significant problem in dental management and has been related to severe dental caries and dental pain. The Dental Fear Survey ( DFS ) is the most widely used measure of dental fear. This study was undertaken to develop the Korean version of the DFS ( K-DFS ) and test its reliability and validity. METHODS: The K-DFS, which uses projective techniques to measure children's and adolescents' dental fear, was developed. The DFS was translated into Korean and participants were selected via convenience sampling. Reliability and validity were tested using data from a sample of 813 middle school students in Gyeonggi Province, selected from the Self questionnaire survey. The K-DFS was administered twice to 102 adolescents aged 12-15 years. RESULTS: The K-DFS had high internal consistency reliability (99.1%) but low test-retest reliability. CONCLUSIONS: The results indicate that the Korean versions of the DFS have good internal consistency reliabilities and test-retest validities. However, we need to further examine the test-retest reliability of the K-DFS and replicate the current study in different samples covering various age groups.

BACKGROUND: There are few previous studies investigating the relationship of dental fear and anxiety (DFA) with dental pain among children and adolescents. To address this issue, we examined the literature published between November 1873 and May 2015 to evaluate the prevalence of DFA and dental pain among children and adolescents, and their relationships with age and sex. METHODS: We performed a broad search of the PubMed database using 3 combinations of the search terms dental fear, anxiety, and dental pain and prevalence. A large proportion of the identified articles could not be used for the review due to inadequate end points or measures, or because of poor study design. Thirty-two papers of acceptable quality were identified and reviewed. RESULTS: We found that the prevalence of DFA was estimated to be 10%, with a decrease in prevalence with age. It was more frequently seen in girls, and was related to dental pain. CONCLUSIONS: We concluded that dental fear, anxiety, and pain are common, and several psychological factors are associated with their development. In order to better understand these relationships, further clinical evaluations and studies are required.

PURPOSE: To estimate the influences of pain and urinary symptoms on quality of life and determine the item that has the most predicting ability for quality of life in young men with chronic prostatitis-like symptoms. MATERIALS AND METHODS: Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. of 28,841 men aged 20 years dwelling in the community, 16,321 men(a response rate 56.6%) completed self-administered questionnaires. A total of 1,057men who complained symptoms suggestive of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined by the logistic regression analysis. The receiver operating characteristic(ROC) curve was used to provide the predicting ability of each item quality of life. RESULTS: In multivariate analysis, pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, and pain contributed more than urinary symptoms. Among items of pain and urinary symptoms, pain severity had the most predicting ability for impact, overall quality of life and quality of life impact domain. The areas under the ROC curves for impact, overall quality of life and quality of life impact domain were 71.3%, 69.3% and 67.0%, respectively. CONCLUSIONS: Urinary symptoms as well as pain may be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influencing factor for quality of life in this population.

Among the four-hundred patients with cerebral aneurysms confirmed by cerebral angiography, we divided them into two age groups, one with ages 39 years or younger(young-aged group: 51 patients, 12.8%), and another with ages 65 years or older(old aged group: 45 patients, 11.3%). A comparison was undertaken in regard to clinical characteristics and overall outcome in two groups. In young-aged group, the female-to-male ratio was 2.2: 1 whereas, women was predominant by five times more in old aged group. Anterior communicating artery aneurysm was the most common site(43.1%) in young-aged group, unlike to old aged group where posterior communicating artery was the most common site(33.3%). The most common symptom was headache in both groups, and the hypertension was more frequent in young-aged group(45.5%) than old-aged group(33.3%). Surgery was performed in 43 patients(84%) in younger group, and 37 patients(82.2%) in elderly group. Young-aged group showed more favorable outcome(91%) than old-aged group(70%).
