OBJECTIVES: This study was conducted to determine whether or not newly proposed high-resolution activity features could provide a superior analytic foundation compared to those commonly used to assess transitions in children's activities, under circumstances in which the types of courses attended exert different situational effects on activity levels. METHODS: From 153 children at a local elementary school, 10 subjects with attention deficit hyperactivity disorder (ADHD) and 7 controls were recruited. Their activity data was collected using an actigraph while they attended school. Ratios of partitioned activity ranges (0.5-2.8 G) during the entire activity were extracted during three classes: art, mathematics, and native language (Korean). Extracted activity features for each participant were compared between the two groups of children (ADHD and control) using graphs and statistical analysis. RESULTS: Activity distributions between ADHD and control groups for each class showed statistically significant differences spread through the entire range in art class compared to native language and mathematics classes. The ADHD group, but not the control group, experienced many significantly different intervals (> 50%) having low to very high activity acceleration regions during the art and languages courses. CONCLUSIONS: Class content appears to influence the activity patterns of ADHD children. Monitoring the actual magnitude and activity counts in a wide range of subjects could facilitate the examination of distributions or patterns of activities. Objective activity measurements made with an actigraph may be useful for monitoring changes in activities in children with ADHD in a timely manner.

PURPOSE: Although acute nonspecific mesenteric lymphadenitis (ANML) is probably common cause of abdominal pain in children, which can be severe enough to be an abdominal emergency, the clinical features of mesenteric lymphadenitis are not clear. Also, a differential diagnosis with acute appendicitis (APPE) is indispensable to avoid serious complications. The clinical features of ANML were determined, and the risk factors for differential diagnosis with APPE were analyzed. METHODS: Between November 2000 and May 2001, data from 26 patients (aged 1 to 11 years) with ANML and 21 patients (aged 2 to 13 years) with APPE were reviewed. ANML was defined as a cluster of five or more lymph nodes measuring 10 mm or greater in their longitudinal diameter in the right lower quadrant (RLQ) without an identifiable specific inflammatory process on the ultrasonographic examination. There were risk factors on patient's history, physical examination, and laboratory examination; the location of abdominal pain, abdominal rigidity, rebound tenderness, fever, nocturnal pain, the vomiting intensity, the diarrhea intensity, the symptom duration, and the peripheral blood leukocytes count. RESULTS: Of the 26 ANML patients and 21 APPE patients, abdominal pain was noted on periumbilical (76.9% vs 14.2%), on RLQ (11.5% vs 71.4%), with abdomen rigidity (7.6% vs 80.9%), with rebound tenderness (0.0% vs 76.1%)(p<0.05), in the lower abdomen (11.5% vs 14.2%), and at night (80.8% vs 100.0%) (p>0.05). The clinical symptoms were vomiting (38.4% vs 90.4%), the vomiting intensity (1.5+/-0.7 [1~3] /day vs 4.5+/-2.9 [1~10] /day), diarrhea (65.3% vs 28.5%) (p<0.05), and fever (61.5% vs 76.2%)(p>0.05). The period to the subsidence of abdominal pain in the ANMA patients was 2.5+/-0.5 (2~3) days. The laboratory data showed a significant difference in the peripheral blood leukocytes count (8,403+/-1,737 [5,900~12,300] /mm3 vs 15,471+/-3,749 [5,400~20,800] /mm3)(p<0.05). Discriminant analysis between ANML and APPE showed that the independent discriminant factors were a vomiting intensity and the peripheral blood leukocytes count and the discriminant power was 95.7%. CONCLUSION: The clinical characteristics of ANML were abrupt onset of periumbilical pain without rigidity or rebound tenderness, a mild vomiting intensity, normal peripheral leukocytes count, and relatively short clinical course. If the abdominal pain persist for more than 3 days, and/or the vomiting intensity is more than 3 times/day, and/or the peripheral leukocytes count is over 13,500/mm3, abdominal ultrasonography is recommended to rule out APPE.

In February 2011, the Korean Society for Sexual Medicine and Andrology (KSSMA) realized the necessity of developing a guideline on erectile dysfunction (ED) appropriate for the local context, and established a committee for the development of a guideline on ED. As many international guidelines based on objective evidence are available, the committee decided to adapt these guidelines for local needs instead of developing a new guideline. Considering the extensive research activities on ED in Korea, data with a high level of evidence among those reported by Korean researchers have been collected and included in the guideline development process. The latest KSSMA guideline on ED has been developed for urologists. The KSSMA hopes that this guideline will help urologists in clinical practice.

Gastritis Cystica Profunda is a rare condition showing multiple small cysts in the mucosa and submucosa of the stomach. These lesions have been found not only at the site of a gastroenterostomy but also in tbe stomchs of patients without any previous surgery. Recently, We witnessed a 56-year old e wale gastritis cystica profunda who had not undergone previous gastric surgery. The UGI and EGD revealed a 3.0 * 4.5 cm sized submucosal mass on the posterior wall of the antrum, and endoscopic ultrasonography(EUS) discovered a thickening of the third layer in which well-defined, round and nearly anechoic areas with posterior enhancement were gathered. They were thought to be cystic lesions. We report a case of gastritis cystica profunda without having had any previous surgery, the diagnosis was made based on findings from the EUS and histologic findings through surgery.

PURPOSE: Delivering bad news is a task that occurs in most medical practices, rendering communication skills essential to competent patient care. The purpose of this study was to identify factors that are associated with scores on an assessment of medical students' communication skills in delivering bad news to help develop more effective curricula to enhance these essential skills. METHODS: One hundred fifty-four fourth-year medical students at Pusan National University were included. Skills for delivering bad news were assessed using the SPIKES protocol in the CPX. The students were categorized into three main groups according to total scores: 'Exceeds expectations (E)', 'Meets expectations (M)', and 'Needs development (N)'. Personal experiences with misfortune and attitudes toward breaking bad news were surveyed, and school records were collected. The differences between the E and N groups were analyzed based on performance test and survey. RESULTS: Compared with students in the N group, E group students acquired significantlyhigher scores on the items of Perception, Invitation, a division of Knowledge, Empathy and Strategy, and Summary but not on Setting and a part of Knowledge. E group students had better records in classes and clerkships. There were no differences in personal experiences and attitudes toward breaking bad news between the groups. CONCLUSION: Personal experience with delivering bad news does not guarantee better communication, and attitudes toward this task do not influence student performance. We expect that deliberate educational programs will have a positive impact on improving communication skills for delivering bad news.
