OBJECTIVE: To investigate the correlation between magnetic resonance imaging (MRI) findings for children with cerebral palsy (CP) and the severity of their developmental disability. METHOD: MRI and M nchener Funktionelle Entwicklungs Diagnostik (MFED) were used for the evaluation of 52 children with CP. MFED quotient (MFED age/corrected age 100) was compared to the MRI findings. RESULTS: Of the 52 MRIs, no abnormalities were found in 7 cases (13%), periventricular leukomalacias (PVLs) in 37 cases (71.2%), corpus callosum abnormalities in 33 cases (63.5%), delayed myelinations in 8 cases (15.4%), congenital brain abnormalities in 6 cases (11.5%), and central sulcus abnormalities in 3 cases (5.8%). Among 27 patients who were born preterm, the major MRI finding was PVL (100%), indicative of a hypoxic brain injury. All patients with a normal MRI were born at term. There were significant correlations between the MFED quotient and the severity of PVL. The ratio of corpus callosum length/brain anteroposterior diameter was correlated with a developmental disability. CONCLUSION: MRI findings for the patients with CP are well correlated with the developmental disabilities and the timing of brain insult.

The study aimed to compare the whitening efficacy of a strip and gel containing 2.9% hydrogen peroxide, using a tooth whitening light activator. The whitening effect was compared through in vitro and in vivo studies. In the in vitro study, we used stained hydroxyapatite (HAP) specimens as artificial teeth. HAP specimens were made using HAP powder and polyvinyl alcohol solution, and stained by modified Stookey's method. A whitening gel and whitening strip were applied to the respective specimens for 20 minutes, with a light activator. The color changes were measured using a colorimeter. In the in vivo study, one group (test 1) used the gel with a light activator and the other group (test 2) used a strip with the same activator for 15 minutes a day, for four consecutive days. An organoleptic evaluation using a Vita shade guide and instrumental evaluation using a Shade eye-NCC (Shofu Co., Japan) were performed. The color change values (ΔE*) in the in vitro study revealed the strip with the light activator to be more effective than the gel with the same activator (p<0.001). In the in vivo study, even though there was no significant difference between the groups with respect to the ΔE*, using either the Shade eye-NCC or the Vita shade guide, the change in yellowness (Δb*) was statistically significant (p=0.024). In conclusion, test 2 group that used 2.9% hydrogen peroxide strip with a light activator, showed a tendency towards increased whitening than test 1 group that used the gel with the same activator; however further studies are needed to validate the above finding.

Background: Branch retinal artery occlusion (BRAO) is characterized by a sudden, painless monocular visual loss. The condition usually has a favorable prognosis but can sometimes cause severe visual loss. Currently, no clinical guidelines are available for the treatment of BRAO.Case Report: A 38-year-old man presented with vision loss. Initial visual acuity was 0.08/1.0 and a lower-altitudinal visual field defect was detected in the right eye. Occlusion of the superior temporal branch of the retinal artery was observed using fluorescein angiography. The patient was diagnosed with BRAO, and intra-arterial thrombolysis (IAT) was performed 11 hours after the first abnormality. The patient demonstrated rapid improvement after IAT. Visual acuity recovered to 0.8/1.0 and only the cecocentral scotoma remained at 5-month follow-up. Conclusion For patients with BRAO and severe vision loss, IAT may be an effective treatment. However, owing to potential complications, this procedure should be reserved for selected patients.

PURPOSE: Gender differences in personality are considered to have biological bases. In an attempt to understand the gender differences of personality on neurobiological bases, we conducted correlation analyses between regional brain glucose metabolism and temperament factors of personality in males and females. MATERIALS AND METHODS: Thirty-six healthy right-handed volunteers (18 males, 33.8+/-17.6 y; 18 females, 36.2+/-20.4 y) underwent FDG PET at resting state. Three temperament factors of personality (novelty seeking (NS), harm avoidance (HA), reward dependence (RD)) were assessed using Cloninger's 240-item Temperament and Character Inventory (TCI) within 10 days of FDG PET scan. Correlation between regional glucose metabolism and each temperament factor was tested using SPM2. RESULTS: In males, a significant negative correlation between NS score and glucose metabolism was observed in the bilateral superior temporal gyri, the hippocampus and the insula, while it was found in the bilateral middle frontal gyri, the right superior temporal gyrus and the left cingulate cortex and the putamen in females. A positive HA correlation was found in the right midbrain and the left cingulate gyrus in males, but in the bilateral basal ganglia in females. A negative RD correlation was observed in the right middle frontal and the left middle temporal gyri in males, while the correlation was found in the bilateral middle frontal gyri and the right basal ganglia and the superior temporal gyrus in females. CONCLUSION: These data demonstrate different cortical and subcortical metabolic correlates of temperament factors of personality between males and females. These results may help understand biological substrate of gender differences in personality and susceptibility to neuropsychiatric illnesses.

OBJECTIVE: The features of childhood attention deficit hyperactivity disorder (ADHD) are significantly associated with adult mood disorders. Some genetic factors may be common to both ADHD and mood disorders underlie the association between these two phenotypes. The present study aimed to determine whether a genetic role may be played by the serotonin transporter-linked polymorphic region (5-HTTLPR) in the childhood ADHD features of adult patients with mood disorders. METHODS: The present study included 232 patients with major depressive disorder (MDD), 154 patients with bipolar disorder (BPD), and 1,288 normal controls. Childhood ADHD features were assessed with the Korean version of the Wender Utah Rating Scale (WURS-K). The total score and the scores of three factors (impulsivity, inattention, and mood instability) from the WURS-K were analyzed to determine whether they were associated with the 5-HTTLPR genotype. RESULTS: In the BPD type II group, the 5-HTTLPR genotype was significantly associated with the total score (p=0.029) and the impulsivity factor (p=0.004) on the WURS-K. However, the inattention and mood instability factors were not associated with the 5-HTTLPR genotype. BPD type I, MDD and normal control groups did not exhibit any significant associations between the WURS-K scores and the 5-HTTLPR genotype. CONCLUSION: The findings suggest that the 5-HTTLPR genotype may play a role in the impulsivity component of childhood ADHD in patients with BPD type II. Because of a small sample size and a single candidate gene, further studies investigating other candidate genes using a larger sample are warranted to determine any common genetic links.

BACKGROUND/AIMS: Helicobacter pylori eradication promotes healing and prevents recurrence of H. pylori associated peptic ulcer disease (PUD). However it is unclear whether H. pylori eradication therapy commenced on the initial course of treatment is more effective compared to therapy at a later course of treatment. We evaluated the optimal commencement time of eradication of H. pylori in patients with hemorrhagic PUD. MATERIALS AND METHODS: Between June 2002 through July 2013, a total of 486 patients who had hemorrhagic PUD were retrospectively evaluated. After exclusion, 79 patients who received H. pylori eradication therapy were assessed. RESULTS: Thirty patients with duodenal ulcer (38%) and 49 patients with gastric ulcer (62%) were enrolled. The overall eradication rate were 96.2%. The eradication rates of early eradication vs. late eradication (divided by standards of 3 days after diagnosis of PUD) were 94.3% vs. 100%, and was not significantly different (P=0.55). CONCLUSIONS: According to our study, medication commencement time does not have an effect on the eradication rate of H. pylori infection in patients with hemorrhagic PUD.

Acute pancreatitis rarely occurs in the postpartum period. Furthermore, there are very few reports of it after cesarean section delivery. A 35-year-old woman presented with dyspnea and abdominal distension on the third day after cesarean section delivery. Under a suspicion of acute pancreatitis, she was initially managed with conservative treatment. However, she developed intra-abdominal fluid collections and gastric bleeding, which were managed with percutaneous drainage, endoscopic hemostasis, and angiographic embolization. She was discharged with good clinical recovery. Postpartum pancreatitis, especially after cesarean section, is rare; however, its management is not different from that for usual pancreatitis.

OBJECTIVE: This study is aimed to evaluate the efficacy and safety of intravenous iron therapy (iron III hydroxide sucrose complex) in ptatients with postoperative anemia following obstetric and gynecologic operations. METHODS: We reviewed the data of 69 patients with postoperative anemia who had undergone obstetric and gynecologic surgery from September 2003 to September 2004, who refused transfusion for correction of post-operative anemia and agreed on treatment with intravenous iron therapy. Iron III hydroxide sucrose complex 200 mg diluted in 100 mL of 0.9% sodium chloride was administrated over 2 hours on postoperative day 1st, 3rd and 5th days. Hemoglobin levels checked and side effects were reviewed. RESULTS: After treatment of intravenous iron therapy, the hemoglobin levels increased rapidly. The lowest hemoglobin levels were observed on postoperative 3rd day but rapid increase of homoglobin levels were observed continously. After 2 weeks from operation, the hemoglobin levels have increased by 0.6+/-1.3 g/dL in the patients with cesarean section and 2.1+/-1.2 g/dL in the patients with gynecology operation. Major side effects such as anaphylaxis and allergic reaction were not observed, and minor side effects were observed in three patients (4%). Emesis, pain on the injection site and skin rash was observed in each patients. CONCLUSION: Intravenous iron sucrose therapy was safe and effective in anemia following obstetric and gynecologic surgery.

Endoscopic metal stent insertion has been widely performed to palliatively treat gastrointestinal (GI) tract obstruction in patients with cancer. The use of metal stents for benign strictures of the GI tract is increasing due to the low risk of major complications other than stent migration. The incidence of acute pancreatitis after placing a GI tract metal stent is rare. Herein, we report a case of acute pancreatitis caused by a covered metal stent that was initially inserted for a benign stricture of a gastroduodenal anastomosis that developed after the operation, then distally migrated, bent into a U-shape, and impacted into the second portion of the duodenum in a 56-year-old female who underwent a Billroth-I gastrectomy due to gastric cancer.
