BACKGROUND: Although studies on dental fear in relation to sex and age have been conducted, there have been few nationwide studies particularly on the youth sector. In addition, no validity and reliability verifications have been implemented for new research groups on the Korean version of the Dental Fear Survey (K-DFS). Therefore, this study aimed to apply the K-DFS developed in a previous study on Korean youth to draw conclusions on dental fear among the youth.METHODS: This study used the K-DFS, a Korean translation of Kleinknecht's Dental Fear Survey for elementary school, middle school, and high school students. This study selected 2,161 young people of various ages as participants and increased the validity of the research results by expanding nationwide the scope of the study area.RESULTS: Differences in fear levels according to sex were higher in boys fear behavior scores than in girls' regarding dental treatment (P < 0.05). Students with dental fear had higher scores on items associated with dental treatment and fear of dental stimuli compared with students without dental fear (P < 0.05). Differences were observed among the three groups (P < 0.05). However, the results of logistic regression analysis showed no statistically significant differences for dental visits based on sex, grade, and other subcomponents (P > 0.05).CONCLUSION: By verifying the validity of the newly developed K-DFS, this research confirmed its utility as a dental fear questionnaire. Therefore, there can be no objection that the grounds for criticism have been established according to conventional wisdom. In the future, however, developing and studying the limits of K-DFS that overcome the factors of dental fear, especially pain, will help reduce dental fear in adolescents.

This study was understand in order to examine the effect of hardness on stress-causing factors, defined in this study as burnout in nursing. The subjects were 248 nurses working in three general hospitals in Taejon. The instruments used for this study were a survey of general characteristics, modified Health-Related Hardiness Scale(HRHS) (25 items), job stress scale (63 items), and burnout scale(20 items). Analysis of data was done through the mean, percentage, Person correlation coefficient, and stepwise multiple regression done with a SAS program. The results of this study are as follows. 1) The average item score for the job stress was high at 4.44. In the subcategories, the highest degree of stress was night duty(5.11), and work overload(4.70), responsibility for extra affairs(4.70), conflict in nurse-doctor relationships(4.69), and low reward (4.63) in that order. 2) In the stepwise multiple regression analysis, hardiness(11.55%) was a significant determinant of burnout along with job stress(17.24%) and job duration(12.94%). The results of this study show that hardiness has an effect on psychological distress caused by stress.

We present a rare case of abdominal compartment syndrome due to a bulimic attack in a 19-year-old female patient with bulimia nervosa. She was admitted to our emergency room with complaints of progressive abdominal pain following bulimia. Computed tomography showed dilated stomach with food and air pressed other visceral organs and major abdominal vessels. Decompression using nasogastric tube or gastric lavage tube failed. At laparotomy, we performed gastrotomy and decompression was performed. After decompression, she fell into hypovolemic shock due to bleeding in the intra-gastric and peritoneal cavity. Twelve hours after the operation, the patient died due to refractory hypovolemic shock from uncontrolled bleeding following decompression of abdominal compartment. It should keep in mind that binge-eating habits in patients with bulimic nervosa could cause abdominal compartment syndrome due to gastric distension and this may be a potentially fatal condition.

The osteopoikilosis is commonly known as harmatoma in which metaphyseal and epiphyseal area of long bones and the bone of pelvis, hands, feet and et al, contain islands of dense cortical bone with normal Harversian system without any symptoms. The radiologic findings of the osteopoikilosis is multitude of oval or well-circumscribed areas of increased density, 2 to 10 mm in size, in symmetrical distribution and normal uptake in bone scan. Buschke-Ollendorff syndrome, which is transmitted by autosomal dominant, is characterized by the association of osteopoikilosis and connective tissue nevi which are popular and symmetrically distributed lesions on chest, back, buttock, thigh or arm. Authors report three Buschke-Ollendorff syndrome, studied by CT scan, MRI, bone scan and bone and skin biopsy, among five patients associated with osteopoikilosis found by simple radiologic study from ten members in one family with their pedigree.

OBJECTIVE: To evaluate the effects of intra-articular injection of shoulder and subscapularis motor point block on painful hemiplegic shoulder. METHOD: Thirty painful hemiplegic shoulder of recent onset stroke were divided randomly into three groups, i.e. group I: range of motion (ROM) exercise only, group II: intra-articular injection with ROM exercise, group III: subscapularis motor point block with ROM exercise. The intra-articular injection of shoulder was done with 20 ml of normal saline, 5 ml of 1% lidocaine, and 40 mg of triamcinolone. The subscapularis motor point block was done with 5 ml of 5% phenol under electromyographic guide. The ROM in external rotation and simple X-ray of shoulder in full abduction were checked in three groups at pre-treatment and post-treatment 3 week, and the glenohumeral abduction and scapulohumeral rhythm were obtained from the shoulder X-ray. RESULTS: There were significant (p<0.05) improvements of glenohumeral abduction, external rotation, and scapulohumeral rhythm of shoulder in group II and III, but improvement of only glenohumeral abduction was significant in group I. Angular increment of glenohumeral abduction and external rotation was most significant in group III compared with other two groups. CONCLUSION: These results suggest that the intra-articular injection of shoulder and subscapularis motor point block are potentially useful techniques in the prevention and management of the painful hemiplegic shoulder.

Prurigo nodularis (PN) is a disease characterized by chronic itch and presence of firm nodules or papules on the skin. The underlying pathophysiology of PN is still under debate, but it has been reported to be due to synergistic neural- and immune-mediated mechanisms. In this review, the authors summarize the etiology, epidemiology, clinical characteristics, and diagnosis of PN and suggest management protocols for patients with PN despite the absence of local guidelines for PN in Korea. The prevalence of PN in Korea was reported as 0.036%, similar to that in other countries. The various etiologies of PN are known to be associated with neural sensitization and inflammation, and the related treatment targets being studied for PN include interleukin-4, 13, 31, and transient receptor potential vanilloid 1 (TRPV1). Understanding of predisposing factors or concomitant diseases is beneficial towards targeted management of patients with PN. In addition, it has been reported that PN is more frequently accompanied by metabolic diseases, or renal disorders compared to other inflammatory skin diseases characterized by itchiness such as atopic dermatitis or psoriasis. The clinical diagnosis of PN is generally based on three core symptoms; chronic pruritus over six weeks, firm lesions, and repeated scratching. To evaluate the severity of PN, the following objective and subjective assessments can be used: Investigator’s Global Assessment for PN or Peak Pruritus Numerical Rating Scale. We propose a localized work-up algorithm for PN. It is expected that the increased awareness of PN can facilitate its diagnosis, thereby reducing the disease burden of patients with PN.

OBJECTIVE: To investigate sympathetic vasomotor response of the hands to cold and warm stress on the foot with Digital Infrared Thermal Imaging (DITI) in normal healthy subjects. METHOD: Fifteen healthy subjects were participated in this study. The DITI was taken during immersing right foot in cold and warm water bath. The thermal images of the dorsal hands were captured at the starting point and then every 5-minute up to 30 minutes. The ratio of temperature between the ending point (30T) and the starting point (0T) was calculated. RESULTS: In cold stress test, the mean 30T/0T ratio were 92.8+/-2.4% and 92.2+/-2.7% in the right and left hands, respectively. There were no statistically significant side to side differences. The temperature of the each hand was significantly lowered at every 5 minutes interval (p<0.05). In warm stress test, the mean 30T/0T ratio were 104.5+/-1.8% and 104.4+/-2.0% in the right and left hands, respectively. The temperature of each hand was significantly increased at the first 5 minutes (p<0.05), and tended to increase until 10 minutes. After then, the temperature was not significantly changed until 30 miniutes. CONCLUSION: We could identify the normal sympathetic vasomotor response to the cold and warm stress with DITI. It might be served as an useful baseline data for the identification of sympathetic dysfunction.

Diabetes mellitus (DM) can accompany many musculoskeletal (MSK) diseases. It is difficult to distinguish the DM-related MSK diseases based on clinical symptoms alone. Sonography is frequently used as a first imaging study for these MSK symptoms and is helpful to differentiate the various DM-related MSK diseases. This pictorial essay focuses on sonographic findings of various MSK diseases that can occur in diabetic patients.

PURPOSE: This study analyzed the correlation between grade point average (GPA) of medical school and the score of Korean Medical Licensing Examination (KMLE). METHODS: This study based on the results of 67th KMLE applicants who graduated from a college of medicine in 2003. We also gathered data of these applicants from the college of medicine: gender, age, type of entrance, GPA of basic medicine, clinical medicine, clinical clerkships and final test scores. We analyzed whether there was discrimination between achievement of KMLE passed and that of KMLE failed, which of variables affected the results of KMLE. RESULTS: 173 applicants passed KMLE among 189. There were significant correlations between basic medicine, clinical medicine, final test score and the score of KMLE (respective p-value; < 0.0001). There were also significant differences of GPA between KMLE passed applicants and failed. Final test scores were the most correlated with those of KMLE. If the GPA of 2nd grade was below 2.5 and the GPA of 3rd year grade was below 2.3, they was a high-risk group for failing KMLE (sensitivity 100%, specificity 90%). CONCLUSION: There were significant correlations between the GPA of medical school and the score of KMLE, and significant differences between KMLE passed applicants and failed. A high-risk group of failing KMLE was the students that the GPA of 2nd grade was below 2.5 and the GPA of 3rd grade was below 2.3.

PURPOSE: We investigated the risk factors related to the development and aggravation of allergic rhinitis, which is associated with residential environment and lifestyle habits of children residing in Incheon. METHODS: A total of 182 children diagnosed with moderate to severe allergic rhinitis and 67 healthy children were enrolled. A detailed questionnaire of the environmental characteristics and the dietary habits were completed by the parents. Further, skin prick tests with 14 common allergens were performed. RESULTS: The mean age of the children with allergic rhinitis and healthy control was 8.2+/-2.8 and 9.4+/-2.0 years, respectively. The presence of indoor mold was associated with an increased risk of development of allergic rhinitis. (adjusted odds ratio [aOR], 4.26; 95% confidence interval [CI], 1.96-9.27) Among the food groups, there was no significant difference of the daily intake of milk and yogurt between the patients and the controls. However, daily intake of vegetables, except Kimchi, and daily intake of fruits or fruit juice were associated with a decreased risk of allergic rhinitis. (aOR, 0.43; 95% CI, 0.20-0.92 / aOR, 0.43; 95% CI, 0.13-0.90, respectively) CONCLUSION: The results indicate that an indoor dampness is one of the risk factors of development and aggravation of allergic rhinitis. Control of indoor humidity and daily intake of fruits and vegetables can prevent the development and control symptoms of allergic rhinitis.
