An unusual case of glroependymal cyst involving the lateral ventricle, 3rd ventricle, cerebellopontine angle cistern and prepontine cistern, simultaneously, is reported. The glroependymal cyst is benign developmental cyst that mainly occurs in the cerebrospinal axis in relation to ventricle, but occasionally occurs in relation to extraventricular system, such as subarachnoid space, brain stem and cerebral parenchyme. The histological characteristics of ependymal cyst wall are ependyma-like epithelium and neuroglial tissue.

STUDY DESIGN: A randomized, controlled animal study. PURPOSE: To investigate the effectiveness of fusion and new bone formation induced by demineralized bone matrix (DBM) strips with jelly strengths. OVERVIEW OF LITERATURE: The form of the DBM can make a difference to the outcome. The effect of different jelly strengths on the ability of DBM to form new bone is not known. METHODS: Forty-eight rabbits were randomized into a control group and two experimental groups. In the control group (group 1), 1.4 g of autologous iliac crest bone was placed bilaterally. In the experimental groups, a high jelly strength DBM-hyaluronic acid (HA)-gelatin strip (group 2) and a low jelly strength DBM-HA-gelatin strip (group 3) were used. The fusion was assessed with manual manipulation and radiographs. The volume of the fusion mass was determined from computed tomographic images. RESULTS: The fusion rates as determined by manual palpation were 37.5%, 93.8% and 50.0% in group 1, group 2, and group 3, respectively (p<0.05). By radiography, the fusion rate of High jelly strength DBM strip was statistically significantly greater than that of the other alternatives (p<0.05). The mean bone volume of the fusion mass as determined by computed tomography was 2,142.2+/-318.5 mm3, 3,132.9+/-632.1 mm3, and 2,741.5+/-380.4 mm3 in group 1, group 2, and group 3, respectively (p<0.05). CONCLUSIONS: These results indicate that differences in the structural and mechanical properties of gelatin that are associated with jelly strength influenced cellular responses such as cell viability and bony tissue ingrowth, facilitating greater bone fusion around high jelly strength implants.

This study was designed for the facial reconstruction of Father Dae -Gun (Andrea) Kim, who is the first priest in Korea. The study was entrusted by Seoul great parish, Myeongdong Cathedral and was conducted during 15 months from September 1999. To reconstruct the face of Father Dae -Gun (Andrea) Kim, we used photographs and metric data of Father Dae -Gun (Andrea) Kim's skull, which was measured by Department of Anatomy, Catholic Medical College at 1971. Based on above data, we found a skull similar to Father Dae -Gun (Andrea) Kim, replicated it, and modified it to be consistent with that of Father Dae -Gun (Andrea) Kim measured at 1971. The face of Father Dae -Gun (Andrea) Kim was reconstructed on the modified replica of Father Dae -Gun (Andrea) Kim's skull using the forensic anthropological data about the average skin depth and the relationships of skull morphology to facial features of Korean. The average skin depth of Korean face was obtained from direct measurement of cadavers and indirect measurement of live Korean using ultrasonography. The result of facial reconstruction of Father Dae -Gun (Andrea) Kim was made as the bronze bust. The forensic anthropologic method such as facial reconstruction is one of the methods to identify unidentified -skull. This study is the first facial reconstruction on the base of Korean physical anthropological data and is thought to be helpful to the facial reconstruction for identification.

Nasopharyngeal tuberculosis is an uncommon disease, and isolated nasopharyngeal tuberculosis is an even rarer condition. An 18-year-old male came to our clinic with left nasal obstruction. Upon physical examination, there was no cervical lymphadenopathy. Nasal endoscopic examination revealed an isolated 2.0x1.5 cm sized pedunculated mass at the midline of the nasopharynx. Histopathological findings of the nasopharyngeal mass showed a caseating granuloma with multinucleated giant cells. He was diagnosed with nasopharyngeal tuberculosis and treated with antituberculous agents. We herein report a case of isolated nasopharyngeal tuberculosis without cervical lymphadenopathy with review of the literature.

PURPOSE: To evaluate the quality and scientific accuracy of internet information regarding precocious puberty. METHODS: We identified websites by entering "precocious puberty" or "early puberty" into 5 search engines from May to July 2011. The top 50 websites from each search engine were included, excluding websites that were duplicate, inaccessible, or had poor information (containing fewer than two subjects of definition, causes, diagnosis, or treatment); 60 sites were identified. We classified the websites according to website author, evaluated the quality with the DISCERN instrument, giving a scientific accuracy with information score (IS) ranging from 0 to 30 points. RESULTS: Analysis of the quality with the DISCERN instrument showed that the majority of websites received low overall ratings regardless of the authors. Assessing the scientific accuracy, the mean IS of oriental websites (10.82) was significantly low compared to that of academic authors (22.61), physician authors (21.50), commercial authors (22.88), and other authors (27.00). CONCLUSION: With the exception of oriental websites, scientifically accurate information was provided on the websites regarding precocious puberty. Most of the analyzed websites showed low reliability. It is important to provide reliable information as well as scientifically accurate information

Ascaris Lumbricoides was the most common helminth in Korea, but the prevalence of ascariais has decreased to 0.05%, so as the incidence of biliary ascariasis. The incidence of pancreatitis due to biliary ascariasis is relatively common in endemic areas, but in Korea only one case has been reported since 1985. A 71-year-old man was admitted with a sudden onset of nausea, vomiting and severe epigastric pain. He was diagnosed as acute pancreatitis based on physical findings and an elevated serum amylase level. Magnetic resonance cholangiopancreatography (MRCP) that was performed on admission revealed diffusely enlarged pancreas with fluid collection and long tubular structure in the common bile duct, which showed intermidiate signal intensity on T1 weighted image and low signal intensity on T2 weighted image. Also, endoscopic retrograde cholangiopancreatography (ERCP) was performed to treat biliary ascariasis. After sphincterotomy, ascaris was extracted by a basket without any complication.

BACKGROUND AND OBJECTIVES: Few studies were evaluated the effect of blindness on outcome in animal models, though a potential effect of blinding has been reported in clinical trials. We evaluated the effects of adipose tissue-derived stem cells (ADSCs) on cavernous nerve injury (CNI)-induced erectile dysfunction (ED) in the rat and examined how proper blinding of the outcome assessor affected treatment effect. METHODS AND RESULTS: We searched in Pubmed, EMBASE, Cochrane and Web of Science databases from inception to January 2019. We included CNI animal model, randomized controlled experiments, and ADSC intervention. Erectile function and structural changes were assessed by intracavernous pressure and mean arterial pressure (ICP/MAP) ratios, neuronal nitric oxide synthase (nNOS) levels, cavernous smooth muscle and collagen (CSM/collagen) ratios, and cyclic guanosine monophosphate (cGMP). RESULTS: Nineteen studies were included in the final meta-analysis. The ICP/MAP ratio of the ADSC treatment group increased compared to the control group (SMD=1.33, 95%CI: 1.11~1.56, I²=72%). The nNOS level (SMD=2.29, 95%CI: 1.74~2.84, I²=75%), CSM/collagen (SMD=2.57, 95%CI: 1.62~3.52; I²=85%), and cGMP (SMD=2.96, 95%CI: 1.82~4.10, I²=62%) were also increased in the ADSC treatment group. Preplanned subgroup analysis was conducted to explore the source of heterogeneity. Five studies with blinded outcome assessment were significantly less effective than the unblinded studies (SMD=1.33, 95%CI: 0.86~1.80; SMD=1.81, 95%CI: 1.17~2.46, respectively). CONCLUSIONS: ADSCs might be effective in improving erectile function and structural change in CNI-induced ED. However, non-blinded outcome assessors might cause detection bias and overestimate treatment efficacy. Therefore, the ADSC efficacy must be further evaluated with a rigorous study design to avoid bias.
