Neurofibromatosis type 1 (NF1; also known as von Recklinghausen's neurofibromatosis) is inherited in an autosomal dominant fashion, although it can also arise due to spontaneous mutation. Gastrointestinal involvement of NF1 is seen in 10% to 25% and causes symptoms in fewer than 5%. Histologically, the gastro intestinal (GI) manifestation of NF1 occurs in three forms: hyperplasia of the gut neural tissue, stromal tumors, and duodenal or periampullary endocrine tumors. A 31-year-old female, diagnosed with NF1, presented with poor oral intake and vomiting for 10 days prior to admission. Preoperative gastrofiberscopic finding was gastric outlet obstructing polypoid duodenal bulb lesion. The patient underwent hemigastrectomy with antecolic gastrojejunostomy due to gastric outlet obstruction. The final pathologic report was submucosal neurofibromatous proliferation with Brunner's gland hyperplasia located at the duodenal bulb in the NF1 patient. We report this case with a review of literatures.

BACKGROUND: Basal cell carcinoma (BCC) is the most common skin cancer. About 74% cases of basal cell cancer occur on the head and neck. Basal cell carcinoma on the face may have a higher degree of subclinical spread than tumors arising elsewhere. And incompletely excised BCCs become more aggressive when they recur. So the surgical removal and reconstruction of BCC located on the face are important to make perfect curing and cosmetic results. METHODS: A retrospective study was done with 128 patients (137 cancers) who were treated with BCC on the face since 1987 to 2011. General data of these cases such as the primary site of cancer, age and sex of the patients, operative methods, and recurrence rate were reviewed. RESULTS: The ratio of men to women was 1:1.4. And 86.9% of the patients with BCC were older than the age of 50 years with the mean age of 65.8 years. The distribution of facial basal cell carcinoma was on the nose, eyelids, cheek, and nasolabial fold. Surgical methods for treatment were local flap, full thickness skin graft, primary closure, and split thickness skin graft. Specifically, local flap consists of V-Y advancement flap, cheek advancement flap, limberg flap, forehead flap, nasolabial flap, rotation flap, transposition flap, bilobed flap, and island flap. Six cases recurred and all of them were treated with reoperation. CONCLUSION: The authors reviewed facial basal cell carcinoma cases in our hospital. This study might be helpful to choose appropriate operation method to manage BCC on face in Korea.

STUDY DESIGN: A prospective radiological assessment was performed using computerized tomography measurements. OBJECTIVES: The aim of this study was to assess the changes in the dimensions of the neural foramen after anterior interbody fusion with posterior fixation in spondylolisthesis. SUMMARY OF LITERATURE REVIEW: Anterior lumbar interbody fusion distracts the height and width of the neural foramen. MATERIALS AND METHODS: Anterior interboody fusion with posterior fixation was performed in twenty-five patients. The sagittal parameters were the height and area of the neural foramen. The fused lumbar segments was imaged in the direct sagittal projections in a CT (SOMATOM Senstaion; SIMENS, Germany) and 1-mm slice thickness before surgery and after solid fusion. Computer digitation was used for the measurements independently by three different observers. Statistical analysis was performed using a Wilcoxon signed test and a paired T-test to determine the correlation between the measurements, and Pearson correlation to determine the level of interobserver and intraobserver agreement. RESULTS: After anterior interbody fusion and posterior fixation, the height and the area of the neural foramen had increased significantly by 15.5+/-14.0%(p.0.001) and 23.2+/-17.7%(p.0.001). There was a significant confidence in interobserver (0.9466~0.9996) and intraobserver(0.8896~0.9991) agreement. CONCLUSIONS: Anterior interbody fusion significantly increased the changes in the dimensions of the neural foramen. Anterior distraction and decompression with anterior interbody fusion increased the area of the neural foramen This study shows that anterior interbody fusion can be used to decompress the neural foramen in the spondylolisthesis.

OBJECTIVES: Patient's behavior features are important factors which influences the clinical judgement including diagnosis. However, most psychiatrists build up a picture of patients' behavior from an amalgamation of their own brief observations and nurses' reports, which often lack in the objectiveness. Several behavioral scales have been developed to alleviate this difficulty, but the poor efficiency and reliability of these scales have made them less useful. The recently developed Ward Daily Behavior Scale is an objective tool for evaluating all the daily noteworthy behaviors of patients, and is easily applicable to wide ranges of diagnoses and ages. This study tried to prove the reliability and validity of the Ward Daily Behavior Scale-Korean version. METHODS: The 112 patients, 63 males and 49 females, at a chronic psychiatric inpatient ward were selected as subjects. Experienced and unexperienced nurses rated patients' behaviors independently with the Ward Daily Behavior Scale-Korean version, after observing behaviors of subjects for 8 hours during day duty time. And then we tested the inter-rater reliability, internal consistency, and concurrent validity of this scale. RESULTS: The Ward Daily Behavior Scale-Korean version proved to be both reliable and valid for measuring of behaviors of psychiatric inpatients. CONCLUSIONS: The Ward Daily Behavior Scale-Korean version will be a valuable tool to observe and quantify patients' behavior in psychiatric wards.

PURPOSE: To evaluate the visual outcome and optical quality in eyes with diffractive multifocal intraocular lens (DMIOL) implantation after myopic refractive surgery. METHODS: Nineteen eyes (15 patients) were implanted with AcriSof ReSTOR(R) SN6AD1, the aspheric DMIOL after myopic refractive surgery (laser-assisted in situ keratomileusis [LASIK] 14 eyes, photorefractive keratectomy [PRK] 4 eyes, laser-assisted subepithelial keratomileusis [LASEK] 1 eye). Preoperative and postoperative visual acuities and manifest refraction were measured. Preoperative corneal higher-order aberrations (HOAs) were measured using Hartmann-Shack (H-S) aberrometer in dilated pupils, and optical qualities were measured 1 month postoperatively using H-S aberrometer and a double-pass system under mesopic conditions. Patient satisfaction was investigated using a questionnaire at 2 months postoperatively. RESULTS: Uncorrected distant and near visual acuities at postoperative 2 months were 0.11 +/- 0.19, and 0.19 +/- 0.12 (log MAR), respectively. Postoperative spherical equivalent (SE) of 16 eyes (84.2%) was within +/-0.50 diopters (D) and all eyes were within +/-1.00 D from emmetropia. Preoperative corneal and postoperative ocular spherical aberrations in a 4.0 mm pupil diameter were 0.08 +/- 0.08 and 0.07 +/- 0.07 (microm), respectively. Objective scatter index was 3.42 +/- 1.71 and modulation transfer function (MTF) cut-off value was 21.03 +/- 12.37 cpd. General satisfaction score was 3.52 +/- 0.96 points out of 5, and 8 patients (11 eyes) were not satisfied with DMIOL implantation. CONCLUSIONS: After DMIOL implantation in the eyes with previous myopic refractive surgery, postoperative SE was close to the target D, but optical qualities and patient satisfaction were poor.

Phlorotannins (marine algal polyphenols) have been reported to exhibit beneficial biological activities, serving as both antioxidants and anti-inflammatory agents. Among marine algae, Ecklonia cava, a member of the Laminariaceae, is a very popular food regarded as healthy in Korea and Japan. Recently, benefits afforded by phlorotannins in the treatment of various clinical conditions have been reported, but any therapeutic effects of such materials in the treatment of neurodegenerative diseases such as stroke remain unclear. Also, the mechanisms of action of the algal components remain poorly understood. In the present in vivo study, administration of Ecklonia cava polyphenols (ECP) at 10 mg/kg and 50 mg/kg intraperitoneally (i.p.) significantly decreased infarct size and the extent of brain edema in the rat after induction of transient focal ischemia via middle cerebral artery occlusion (MCAO). Further, terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay revealed dose-dependent blockage of neuronal apoptosis upon intravenous ECP treatment. Neurobehavioral tests performed over the 6 days after MCAO revealed a reduction in neurological motor performance in control animals, but administration of ECP (50 mg/kg i.p.) prevented this decline. In vitro, a significant neuroprotective effect of ECP was evident when cell viability was assayed after induction of H2O2-mediated oxidative stress, upon retinoic acid treatment, in the differentiated neuroblastoma cell line SH-SY5Y. Interestingly, ECP blocked the rise in cytosolic calcium, in a dose-dependent manner, in differentiated SH-SY5Y cells exposed to H2O2. Together, the results suggest that ECP exerts neuroprotective effects in the focally ischemic brain by reducing Ca(2+)-mediated neurotoxicity.

Post-menopausal osteoporosis (PMO) is a major global human health concern. Owing to the need for therapeutic drugs without side effects, natural extracts containing various polyphenolic compounds that may exert estrogenic effects have been studied in depth. Rhus verniciflua Stokes (RVS), which has been used as a traditional herbal medicine for centuries in Korea, was recently revealed to exert estrogenic effects attributable to its bioactive ingredients sulfuretin and butein, which have strong estrogen receptor–binding affinities. In this study, the protective potential of RVS in PMO was evaluated by using an experimental animal model of PMO, which was established by ovariectomy (OVX) of female Sprague Dawley rats. The oral administration of RVS at 20 mg/kg or 100 mg/kg for 8 weeks markedly protected against OVX-induced atrophy of the uterine tube and reversed the elevation in the ratio of serum receptor activator of nuclear factor-κB ligand to osteoprotegerin, which is a marker of disease severity. In addition, RVS inhibited OVX-induced tibia bone loss, activated osteogenic activity, and suppressed osteoclastic activity in the tibial epiphyseal plate, a region of bone remodeling. Collectively, these factors indicated that the oral intake of RVS might be beneficial for the prevention of PMO.

As chorion and amnion fusion usually occurs between 14 and 16 weeks of gestation, sonographic identification of chorion and amniotic membrane separation is a normal finding before 14 weeks. However, persistent separation after 16 weeks of gestation is considered rare and abnormal findings. Complete chorioamniotic membrane separation (CMS) may occur spontaneously, but has also been described as a complication of all invasive intrauterine procedures, including amniocentesis. Complete CMS have a significant morbidity and mortality due to intrauterine fetal death, cord complications, and preterm delivery. Aggressive treatment with hospitalization is necessary. We now report 2 cases of complete CMS identified by prenatal ultrasound; 1 in spontaneous complete CMS diagnosed at 24 weeks of gestation, and health premature child was born at 29+3 weeks of gestation, who was alive and well at present; 1 in complete CMS diagnosed at 21 weeks of gestation after amniocentesis, and fetal demise at 24 weeks of gestation due to cord strangulation by an amniotic band. We experienced two cases of complete CMS and report with a brief review of literatures.
