Shaken baby syndrome refers to the group of nonaccidental injuries occuring in infants and children as a consequence of violent shaking. The characteristic injuries include subdural and subarachnoid hemorrhages, retinal hemorrhages, traction-typed metaphyseal fracture of long bone and fractures of the ribs. General physical findings may include bruising and burns, but sometimes no extracranial injuries are detected. Affected children are nearly always under 2 years of age or younger. Common symptoms include lethargy, irritability, seizures, increased or decreased muscle tone, poor feeding, impaired consciousness, vomiting and apnea. We experienced a case of shaken baby syndrome in a 3-month-old girl. Although the history of trauma(shaking) is little known, our findings of clinical and radiographic features corresponded to shaken baby syndrome. (J Korean Pediatr Soc 2000;43:851-855)

This study was performed to investigate the factors related to tooth wear. For this study, 78 patients with temporomandibular disorders and 76 dental students without any signs and symptoms of temporomandibular disorders were selected as the patients group and as the normal group, respectively. Preferred chewing side, Angle's classification, lateral guidance pattern, head and shoulder posture wee observed clinically. Electromyographic activity of anterior temporalis and masseter muscle were recorded with BioEMG and occlusal status were recorded with T-Scan . Wear facet area of each tooth was measured from working model of upper arch corresponding to the occlusal status from T-Scan, Wear facet area were measured with planimeter in mm2. Total area were divided into incisal, canine, posterior tooth area. Anterior wearfacet area was incisor area plus canine area, and unilateral area was anterior area plus posterior area. The data collected were analyzed by SAS statistical program and the results of this study were as follows: 1. There was no significant difference between the two groups in total werafacet area, and male subjects showed tendency to have larger area in the normal group but female subjects showed tendency vice versa. 2. There was no significant difference related to preferred chewing side and Angle's classification, however, some difference was observed by lateral guidance pattern. Anterior wear facet area in subjects of canine guidance was the largest in the three subgroups. 3. Subjects with head tilting to right side had larger posterior and total area, and subjects with higher shoulder in right side had larger canine and anterior area than any other subgrous. 4. Electromyographic activity of masseter muscle was more correlated with wear facet area than anterior temporalis muscle, and tooth contact number and force were significantly correlated with wear facet area, but the most important factor affecting tooth attrition was age.

PURPOSE: The aim of this study is that the prevalence of rotavirus infection was evaluated by each group and clinical features of group A, B and C rotaviruses infections were described respectively to compare one with another. METHODS: Between January 2010 and December 2010, we enrolled a group of children below 10 years of age admitted for management of acute diarrhea at the Catholic University of Korea Bucheon St. Mary's Hospital. A total of 310 stool samples documented to be free of common bacterial pathogens were collected from children with diarrhea. The presence of group A, B or C rotavirus is indicated by amplification of DNA segments of the expected lengths after the first and second PCRs. RESULTS: In a total of 310 stool specimens, 40 (12.9%) specimens were positive for rotaviruses. These included 23 (7.4%) positive for group A, 5 (1.6%) for group B and 12 (3.9%) for group C rotaviruses. Group B rotavirus infected patients had significantly less diarrheas per day (group A: P=0.01, group C: P=0.01) and shorter duration of vomiting days (group A: P=0.03, group C: P=0.03) than those with group A and C rotaviruses infection respectively. All the group B rotaviruses had been isolated in March and October. Group C rotavirus infections were prevalent during late summer and early winter and peaked in October. CONCLUSION: These findings indicate that group B and C rotaviruses are notable causes or the contributing causes of diarrhea among infants and children in Korea.

OBJECTIVE: The present study was undertaken to examine the effects of magnesium ion in the culture medium on the development of mouse fertilized oocytes either before or after pronuclear formation, and to investigate whether the effect of magnesium ion is related with the redistributional change of mitochondria. METHODS: Fertilized oocytes obtained from the oviducts of mice at 15 hr after hCG injection before pronuclear formation (pre-PN) or 21 hr after hCG injection after pronuclear formation (post-PN) were used. The embryos were cultured for 3 days with basic T6 medium-magnesium free and various concentrations of magnesium ion, 0.0, 0.5, 1.0, 2.0, 4.0 or 8.0 mM, respectively. After culture, the developmental stages of embryos and the number of nuclei were evaluated. To observe the effects of magnesium ion on the mitochondrial distribution, fertilized oocytes were collected at 21 hr after hCG injection and cultured for 6 hr with various concentration of magnesium ion. As a control, fertilized oocytes with pronuclei at 27 hr after hCG injection were used. RESULTS: The concentration of magnesium ion to accelerate the in vitro development of mouse fertilized oocytes appeared to be at 2.0 mM for the pre-PN and the post-PN stage embryos. In the mitochondrial redistribution patterns, the embryos cultured in 2.0 mM concentration of magnesium ion showed the highest percentage (22.6%) of distinct perinuclear clustering pattern comparing to other experimental group. CONCLUSION: The effect of magnesium ion may be related to the cytoplasmic redistribution of mitochondria. This relationship seems to connect the developmental competence of preimplantation mouse embryos in vitro. These results can suggest that higher concentration of magnesium ion (2.0 mM) than those of conventional culture medium (0.2~1.2 mM) is more suitable for in vitro culture of preimplantation mouse embryos.

BACKGROUND: The purpose of this study was to investigate the outcomes after fixation using a 3.5-mm locking compression plate (LCP) hook plate for isolated greater tuberosity (GT) fractures of the proximal humerus. METHODS: We evaluated the postoperative radiological and clinical outcomes in nine patients who were followed up at least 1 year with isolated GT fractures. Using the deltopectoral approach, we fixed the displaced GT fragments with a 3.5-mm LCP hook plate (Synthes, West Chester, PA, USA). Depending on the fracture patterns, the hook plate was fixed with or without augmentation using either tension suture or suture anchor fixation. RESULTS: All the patient showed successful bone union. The mean time-to-union was 11 weeks. The radiological and clinical outcomes at the final follow-up were generally satisfactory. The mean visual analogue scale for pain, the University of California at Los Angeles score, the American Shoulder and Elbow Surgeons score, and the subjective shoulder value were 1.4, 30.3, 84.3, and 82.2%, respectively. The mean active forward flexion, abduction, external rotation, and internal rotation of the shoulder were 156.7°, 152.2°, 61.1°, and the 10th thoracic vertebral level, respectively. Only one patient presented with a postoperative complication of shoulder stiffness. The patient was treated through arthroscopic capsular release on the 5th postoperative month. CONCLUSIONS: We conclude that fixation using 3.5-mm LCP hook plates for isolated GT fractures of the proximal humerus is a useful treatment method that provides satisfactory clinical and radiological outcomes.
