Entrapment of the extensor pollicis longus tendon is reported rarely on Smith's fractures in children. In our case, a 15 year old boy with Smith's fracture received treatment of closed reduction at another hospital. When he visited our hospital, a wide gap at the fracture site was detected on radiograph and the thumb movement was limited. We have doubt the entrapment of the soft tissue, especially the tendon. We decided on open reduction. In the operation field, entrapment of the extensor pollicis longus tendon at the gap of the fracture site was found through dorsal approach. In addition, fracture treatment with K-wire fixation after reduction of extensonr pollicis longus tendon reduction was done. Therefore, we report this case with a review of the literatures.

Norovirus (NV) has caused large outbreaks of gastroenteritis in schools. Studies of NV epidemiology in schools related to NV outbreaks have been frequently reported. However, reports of that in schools without outbreaks are not found. Presently, NV molecular epidemiology surveillance was carried out in asymptomatic food handlers working at nonoutbreak elementary schools in Incheon, Korea, in March, April and December, 2009. NV prevalence was examined by real-time reverse transcription-PCR (RT-PCR) and the positive products were re-evaluated by conventional RT-PCR for sequencing. Fecal samples (n = 776) were collected from 776 food handlers in 60 schools. NV was detected in 26 of them (3.4%). Of these, 17 (65%) were positive for NV GII and 10 (38%) were positive for NV GI. Of the 26 samples, 19 were positive by conventional RT-PCR. Sequencing of these 19 strains revealed GII/4 (n = 5), GI/6 (n = 3), GI/14 (n = 2), GII/8 (n = 2), GI/2 (n = 2), GI/10 (n = 1), GII/1 (n = 1), GII/3 (n = 1), GII/7 (n = 1), and GII/16 (n = 1). In this survey, the food handler population unrelated to NV outbreaks was found to normally contain asymptomatic carriers of NV. The excretion of NV from asymptomatic food handlers should be an infection source of NV outbreaks.

Abdominal pregnancy that is a life threatening variant of ectopic pregnancy, has been a rare event with high maternal mortality. It is very difficult to diagnose a abdominal pregnancy clinically. We have experienced a case of early abdominal pregnancy diagnosed at emergency laparotomy and this case was presented with a brief review of the literatures.

BACKGROUND: Hyperlipidemia has been known as an independent risk factor in the develop-ment of coronary artery disease. This study was carried out to compare nutrient intakes, smo-king status, antioxidant vitamins, and plasma lipids in patients with coronary heart disease (CHD) and in normal healthy subjects among Korean population in Taegu. Possible causes of this dis-ease in patients are discussed. METHODS: Anthropometric assessments included mean intakes of nutrients, and the levels of plasma lipids (apolipoprotein [Apo] A - I, Lipoprotein [Lp] [a]), and antioxidant vitamins (such as vitamins A and E) were measured in female and male subjects with CHD against healthy con-trols. RESULTS: Dietary cholesterol and fat intakes were significantly higher in CHD groups in men and women. Total plasma cholesterol, LDL-C, triglyceride, thiobarbituric acid reactive subst-ance (TBARS), atherogenic index and Lp (a) levels were significantly higher in CHD patients than in the normal group in both men and women. Apo A-I, HDL-C and vitamin E levels were lower in CHD patients than in the normal group. The number of smokers was higher in CHD patients than in the normal group in both sexes of subjects. CONCLUSION: High fat and high cholesterol intakes seemed to be a major factor for the hyperlipidemia in the CHD patients. Their abnormal lipoprotein profile, which appeared in pati-ent plasma, corresponded well to dietary intake patterns. However, long term studies are need-ed to investigate the effects of smoking on lipid metabolism in CHD patients among the Korean population.

Background: Sleep disturbances are common in children and adolescents. However, they are rarely diagnosed and treated because parents, who often report the symptoms, may fail to notice the problems. Factors that can affect parent-child discrepancy include child’s diagnosis, parent’s occupation, and child’s sex. The current study retrospectively analyzed the effect of these factors on parent-child discrepancies of sleep disturbance scores. Methods: Data for sleep-related items in Youth Self-Report (YSR) and Child Behavior Checklist (CBCL) from 2014 to 2020 August in South Korea were collected from psychiatric outpatient clinics at Konkuk University Medical Center and Soonchunhyang University Hospital. Results: A three-way analysis of variance revealed main effect of diagnosis type and interaction between diagnosis type and mother’s occupation. Discrepancies were greater for mood and anxiety disorders compared to conduct-related disorder. Interaction effect revealed greater discrepancies in mood disorders for reports completed by working mothers compared to homemaker mothers. Conclusion The results of this study emphasize the need to explore with caution the selfreported sleep disturbances in adolescents, especially in those with mood disorders. The results also suggest that mother’s occupation should be taken into account when evaluating sleep reports of parents and adolescents.

BACKGROUND: The purpose of this study was to elucidate the effects of fluid on the acid-base and electrolytes status and renal function after kidney transplantation (KT). METHODS: We retrospectively analyzed 103 patients who underwent KT. Analyses were performed separately according to the donor type (living, 52; deceased, 51). In the living donor KT group, 28 patients received normal saline solution (NS) and 24 patients received Hartmann's solution (HS). In the deceased donor KT group, 27 patients received NS, and 24 received HS. The acid-base and electrolyte status, urine volume, and renal function between patients receiving NS and patients receiving HS were compared in each group. RESULTS: Regardless of donor type, there were no differences in potassium, pH, base excess, PCO2 and HCO3 between HS and NS on immediate postoperative and postoperative day 1. However, changes to neutral acid-base balance in terms of pH, HCO3, and base excess were significantly higher in HS than in NS. In living donor KT, NS increased serum potassium and chloride significantly during fluid therapy. On postoperative day 7, renal function showed no difference between two groups but urine volume was significantly larger in NS than in HS. CONCLUSIONS: HS does not increase the incidence of hyperkalemia after KT. The use of HS resulted in less metabolic acidosis than the use of NS. Renal function was similar but polyuria was more severe in patients who received NS than in those who received HS.

PURPOSE: We assessed the repeatability and reproducibility of abutment teeth dental impressions, digitized with a blue light scanner, by comparing the discrepancies in repeatability and reproducibility values for different types of abutment teeth. MATERIALS AND METHODS: To evaluate repeatability, impressions of the canine, first premolar, and first molar, prepared for ceramic crowns, were repeatedly scanned to acquire 5 sets of 3-dimensional data via stereolithography (STL) files. Point clouds were compared and the error sizes were measured (n=10, per type). To evaluate reproducibility, the impressions were rotated by 10-20° on the table and scanned. These data were compared to the first STL data and the error sizes were measured (n=5, per type). One-way analysis of variance was used to assess the repeatability and reproducibility of the 3 types of teeth, and Tukey honest significant differences (HSD) multiple comparison test was used for post hoc comparisons (α=.05). RESULTS: The differences with regard to repeatability were 4.5, 2.7, and 3.1 µm for the canine, premolar, and molar, indicating the poorest repeatability for the canine (P<.001). For reproducibility, the differences were 6.6, 5.8, and 11.0 µm indicating the poorest reproducibility for the molar (P=.007). CONCLUSION: Our results indicated that impressions of individual abutment teeth, digitized with a blue light scanner, had good repeatability and reproducibility.

OBJECTIVES: It has been known that there is a difference in anogenital distance (AGD) in the animals and newborn depending on the exposure of androgenic hormones. The anatomical changes occur in the female genitalia in women after menopause. This was pilot study to find out whether the menopause affects AGD. METHODS: We evaluated a total of 50 women targeted for premenopausal and postmenopausal group in each 25 people. AGD was defined as a length between the posterior commissure of labia and anal center. AGD was measured in lithotomy position using sterile paper ruler. In order to control bias of the height and weight, which could influence the AGD, anogenital index (AGI) is defined as the weight divided by the AGD value. We used a Mann-Whitney U test to analyze the relationship between AGD and menopause for statistical analysis. RESULTS: AGD was significantly longer in premenopausal women compared to postmenopausal women (34.8 +/- 6.4 vs. 30.3 +/- 6.6, P = 0.019). AGI was significantly higher in premenopausal women than postmenopausal women (1.7 +/- 0.4 vs. 1.3 +/- 0.3, P < or = 0.000). CONCLUSION: The changes of AGD and AGI in postmenopausal women demonstrated to have potential to be used as on scale predicting the physical changes that may occur after menopause. This study could be used as the cornerstone of a large-scale studies in the future.

As neonates are brought to the emergency department (ED) for various complaints, it is challenging for emergency physicians to clinically determine the urgency of the visit. We sought to explore clinical characteristics associated with urgent visits to the ED. We conducted a retrospective study by reviewing medical records of neonatal visits to a tertiary pediatric regional emergency center for 5 years. Cases of patients who were discharged after checking only chest or abdominal X-ray or discharged without workup, were classified as non-urgent visits. Cases where more examinations were performed, or when the patient was hospitalized, were classified as urgent visits. Various clinical features and process in the ED were compared between the groups. Of the 1,008 cases enrolled in this study, 856 (84.9%) were urgent and 152 (15.1%) were non-urgent visits. After adjustment by multiple logistic regression analysis, non-urgent visits were associated with self-referrals rather than physician-referrals (odds ratio [OR], 5.96), visits in the evening rather than at night or daytime (OR, 2.51), patient visits from home rather than from medical facilities (OR, 2.19; 95). Fever and jaundice were the most common complaints (25.7% and 24.5%, respectively), and their OR of non-urgent visit was relatively low (adjusted OR 0.03 and 0.03, respectively). However, other common complaints, such as vomiting and cough (7.4% and 7.1%, respectively), were more likely to be non-urgent visits (adjusted OR 2.96 and 9.83, respectively). For suspected non-urgent visits, emergency physicians need to try to reduce unnecessary workup and shorten length of stay in ED.

STUDY DESIGN: A retrospective study. OBJECTIVES: To evaluate the safety and usefulness of implant removal based on fusion by radiological change analyses and non-fused segment motion angle after open reduction, multi-segment fixation, and single segment fusion. SUMMARY OF LITERATURE REVIEW: There have been reports that discuss possible fracture of fixator, loss of reduction, or failure of fixation in certain cases of single segment fixation consistent with thoracolumbar fracture. MATERIALS AND METHODS: We analyzed 83 patients who had undergone treatment by fixation of the top 2 segments and the bottom segment. The posterolateral fusions were performed for the top segment for thoracolumbar fractures. The mean follow-up was 21.3 months. Wedge and local kyphotic angles, anterior, and posterior heights of the vertebral body were measured on plain radiograph. The range of motion of each segment was recorded by flexion-extension lateral radiographs at 6 month after the removal of implants. RESULTS: Radiologic assessments performed on 83 patients demonstrated preoperative mean wedge angle, kyphotic angle, mean anterior body height of 20.1degrees, 18.5degrees and 62.0%, respectively, and, postoperatively, these were corrected by 9.0degrees, 9.3degrees and 24.6%, respectively. In the 44 cases that had the implants removed, the correction losses were 0.4degrees(P=0.258) and 3.7degrees(P=0.000), 0.5%(P=0.756), and at the last follow-up, compared to measurements prior to the removal. There was no statistical significance in wedge angle or anterior body height. The range of motion measured on the non-fused segment was 3.9degrees on average at 6-months after the hardware removal. CONCLUSIONS: The multi-segments fixation and single-segment fusion for the thoracolumbar fracture can preserve correction and the motion of non-fusion segment. Although the implant removal after union can sustain motion, further studies regarding degenerative change of the non-fused segment are necessary.
