PURPOSE: To report a case of primary conjunctival giant cell tumor (GCT). CASE SUMMARY: A 67-year-old female visited our clinic with the chief complaint of a 10-year-history of conjunctival mass in the left eye. The patient had no marked changes in the mass size, and her visual acuity and intraocular pressure were within the normal range. The protruding conjunctival mass invaded the limbal area at the 8 o’clock direction in the left eye and was 5 × 4 × 2 mm in size. Moreover, the pink-colored mass had a lobulated shape with a well-defined margin. In the adjacent mass region, concurrent presence of the conjunctival injection was observed. However, the patient did not exhibit pain or tenderness. We performed wide excision of the conjunctival mass concomitantly with amniotic membrane transplantation. Then, histopathological examinations and immunohistochemical staining of the surgical site were performed. On histopathology, the patient had findings suggestive of GCT. Additionally, immunohistochemistry was positive for CD68 and vimentin. leading to the final diagnosis of GCT. CONCLUSIONS: To our knowledge, this is the first case of GCT of the conjunctiva, which has not been described in the literature. Our case highlights the importance of differential diagnosis from other protuberant conjunctival tumors. A complete removal of GCT of the conjunctiva and a recovery of aesthetic outcomes can be achieved by surgical excision of the mass.

This study was performed to evaluate the effect of hydrogen peroxide-producing Lactobacillus acidophilus V-2Oonthe replication of periodontal pathogens, Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis. When A. actinomycetemcomitam and P. gingivalis were incubated alone and in the combination with L. acidophilus V-20, the viable cell numbers of A. actinomycetemcomitans and P. gingivalis were compared between those cultures. The effect of S. mutans, E. durans, and L. lactis on the replication of A. actinomycetemcomitans and P. gingivalis was also evaluated. The change of periodontal indexes(probine depth, gingival index, GCF volume) and the viable cell numbers of A. actinomycetemcomitans and black pigmented bdcteroides in subgingival plaque sample were evaluated following gargling of fermented milk made from L. acidophilus V-20 for 1 month on patients with periodontal disease in maintenance phase. In the mixed culture of L. acidophilus V-20 and A. actinomycetemcomitans or P. gingivalis, the replication of A. adinomycetemcomitam or P. gingivalis was completely inhibited. But in the mixed culture of P. gingivalis and hydrogen peroxide-nonproducing Lactobacillus casei, the viable cell numbers of P. gingivalis was not decreased when compared with the numbers in the mixed culture of P. gingivalis and L. acidophilus V-20. In the mixed culture of A. actinomycetemcomitam and S. mutans, E. durans, or L. lactis, the viable cell number of A. adinomycetemcomitans was not almost changed when compared with the numbers in the culture of A. actinomycetemcomitans alone. And in the mixed culture of P. gingivalis and E. durans or L. lactis, the viable cell numbers of P. gingivalis was not almost changed compared with the counts in the culture of P. gingivalis alone. But the replication of P. gingivalis was completely inhibited in the mixed culture of P. gingivalis and S. mutans. When the change of periodontal indexes following gargling of fermented milk was compared with baseline, probing depth and gingival index were not changed, but GCF volume was significantly dcreased(p (0.05). And when the viable cell numbers of microorganisms in subgingival plaque sample were compared with baseline, total viable cell number was almost unchanged and the viable cell numbers of A. actinomycetemcomitans and black pigmented bdcteroides were significantly decreased(p<0.05). These results suggest that L. acidophilus V-20 inhibit the replication of A. actinomycetemcomitans and black pigmented bacteroides by the formation of hydrogen peroxide.

Angiodysplasia is an important vascular lesion of the gastointestinal tract , located at the site of ectasia of intestinal submucosal veins and overlying mucosal capillaries. It is a major cause of morbidity from gastrointestinal bleeding in old age, but rather rare in children. Its cause is still unknown, though is mostly considered to be acquired as a result of a degenerative process associated with aging. We experienced a case of colonic angiodysplasia in 14-year old boy, diagnosed by colonoscopy. The patient had a history of repeated hematochezia for a year. This report summarized our case and reviewed the literature.

Lindera obtusiloba has been widely used as a traditional medicine for the treatment of lots of diseases, including abdominal pain, bruise, and hepatocirrhosis. Here in this study, we elucidated the lifespan-extending effect of methanolic extract of Lindera obtusiloba (MLO) using Caenorhabditis elegans model system. We found that MLO has potent lifespan extension activities under normal culture condition. Then, we determined the protective effects of MLO on the stress conditions such as osmotic, thermal and oxidative stress. To reveal possible mechanism of MLO-mediated lifespan, we further investigated the effect of MLO on the antioxidant enzyme activities and intracellular ROS levels. Our results demonstrated that superoxide dismutase and catalase activities were significantly up-regulated by MLO treatment, resulted in reduced intracellular ROS levels. In this work, we also tested whether MLO-mediated longevity activity was associated with aging-related factors such as food intake and growth. Our data revealed that both of pharyngeal pumping rate and body length were significantly shifted by MLO treatment, indicating these factors were involved in MLO's lifespan-extension effects. Although MLO induces reduction in food intake, the body movement of MLO-fed aged worms was not decreased, compared to untreated control worms, indicating MLO might extend lifespan without affecting healthspan.

STUDY DESIGN: A retrospective study OBJECTIVES: To introduce the technique of minimally invasive transforaminal lumbar interbody fusion and examine its clinical and radiologic results. SUMMARY OF LITERATURE REVIEW: Transforaminal lumbar interbody fusion with a mini-incision using a tubular retractor was recently developed. The aim of this procedure is to reduce the approach-related morbidity and achieve better results in an effective and safe manner. MATERIALS AND METHODS: Thirty eight patients were followed up for more than 1 year. Their mean age was 57 years and the mean follow-up was 19 months. The diagnosis was spinal stenosis, spondylolisthesis and recurred herniated nucleus pulposus in 22, 14 and 2 patients, respectively. The Oswestry disability index, intervertebral disc space height, fusion rate and complications were evaluated. RESULTS: The Oswestry disability index improved from 30 points (range, 50~16 points) to 10 points (range, 2-24 points) at the last follow-up. Thirty-four patients (90%) showed excellent or good results. The intervertebral disc space height increased from 8.7 mm to 10.8 mm. Two cases showed nonunion but the clinical results were good. Complications included one case of infectious spondylitis requiring antibiotics, one case of cage dislodgement requiring additional surgery and one case of a pedicle screw malposition showing no clinical symptoms. CONCLUSIONS: Minimally invasive transforaminal lumbar interbody fusion reduced the soft tissue injury and blood loss and shortened the recovery period compared to the traditional open techniques.

PURPOSE: This study is to evaluate the clinical significance and possible etiologies of abnormal neurosonographic findings that revealed linear or branching linear hyperechoic vascular lesions in the thalami and basal ganglia of neonates and infants. METHODS: Analysis of 2,866 cranial sonograms (US) and doppler ultrasonography obtained from 1,150 patients identified 53 patients with linear hyperechoic vascular lesions in the thalami or basal ganglia. Patients with only punctate or coarse, nonlinear lesions of echogenicity in these lesions were excluded. Clinical records in 53 patients were reviewed for documentation of congenital cytomegalovirus (CMV) infection, rubella, syphilis, toxoplasmosis, chromosomal abnormality and other major diagnoses. Brain computed tomography (CT) had been performed in 23 of the 53 patients and these images were compared with the cranial sonograms. RESULTS: There were five CMV infection, two congenital syphilis, three Down syndrome, and one Patau syndrome patients. Other major diagnoses encountered included perinatal asphyxia, ventriculomegaly, intraventricular hemorrhage, periventricular leukomalacia, small-for-gestational age, prematurity with hyaline membrane disease, multiple congenital anomalies, neonatal seizure, meningitis, congenital choroid plexus cyst, neonatal hyperbilirubinemia, congenital heart disease, bronchopulmonary dysplasia and others. Brain CT found small calcification in basal ganglia from one patient. Resolution of lesions found in 5 cases with follow-up US studies. CONCLUSION: A broad etiologic basis for linear hyperechoic vascular lesions in the thalami and basal ganglia of neonates and infants indicates complete screening for possible various etiologies.

PURPOSE: To report a rare case of primary orbital synovial sarcoma. CASE SUMMARY: A 55-year-old male visited our clinic with a 2-month history of decreased visual field in the left eye. The best corrected visual acuity of the left eye was 1.0, and 2.5 mm of proptosis was observed. There was slight limitations in motility and a mild visual field defect in the inferotemporal quadrant of the left eye. Funduscopic examination of the left eye revealed papilledema. Orbital magnetic resonance imaging (MRI) demonstrated the presence of an orbital mass that extended inferotemporally into the left orbit. On magnetic resonance imaging, a well-demarcated and 2.7 x 2.0 x 2.2 cm sized tumor was identified with intermediate signal intensities on T1/T2-weighted scans with slight homogenous enhancement. We approached the orbital mass using a lateral conjunctival incision with left canthotomy and cantholysis and performed partial surgical resection of the mass because the mass encircled the optic nerve. The mass was diagnosed as synovial sarcoma based on the findings of both histopathology and immunohistochemical staining. Postoperatively, the patient underwent radiation therapy to the rest of the tumor site. CONCLUSIONS: Synovial sarcoma should be considered in the differential diagnosis of an orbital mass lesion encircling the optic nerve. Radiation therapy is useful to treat completely unresectable primary synovial sarcoma.
