Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. 82 cases of traumatic optic neuropathy were investigated to evaluate the effectiveness of high dose corticosteroid for the visual improvement. Age, sex, initial visual acuity, final visual acuity, interval to treatment, the type of trauma and the affected region were studied retrospectively.250 mg of Methylprednisolone was administered intravenously every 6 hours for 3 days, and then followed by tapering using oral prednisone The vision was improved in 36 of 82 cases[43.9%]. It was difficult to interpret the relation-ships between the affected region and visual improvement, the interval for each treatment and final visual acuity. However, the vision was improved in 45 of 50 cases who had an initial visual acuity of above light perception, but in the two of 32 cases with no light perception. If indicated, fifteen cases were treated with a combination of high dose corticosteroid and optic nerve decompression. In initial treatment of traumatic optic neuropathy, high dose corticosteroid was effecive. Whether or not initial visual acuity was better than light perception was a key risk factor in the outcome.

Animal models are useful tools to study the molecular basis of schizophrenia pathophysiology and efficacy of potential therapeutic agents. Schizophrenia animal models can be subdivided into three classes ; drug-induced models, genetic models, and environmental models and each model is designed based on specific traits corresponding to the characteristic symptoms of human schizophrenia patients. Psychomotor agitation and sensitivity to psychotomimetic drugs are often thought to reflect positive symptoms. Social interaction deficits and affective impairments are known to correspond to negative symptoms. Also, cognitive symptoms have been linked to the working memory impairments, attention deficits and related cognitive deficits in animals. To analyze such components in quantifiable manners, various behavioral paradigms have been developed and utilized. Here, we overview these animal models, focusing on underlying rationales for their use in the context of schizophrenia research.

Synovial sarcoma is an uncommon, highly malignant soft tissue tumor usually arising from the synovial lining of a joint, bursa and tendon sheath. Occurence in muscle fascia is extremely rare. We present a case of synovial sarcoma of the left calf muscle fascia, which was confirmed by microscopically sarcomatous growth of spindle cells and irregular small multiloculation. Above knee amputation was done.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

PURPOSE: The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS: A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS: In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 +/- 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). CONCLUSION: Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival.

A retrospective study was designed to evaluate the clinical characteristics of canalicular injury including causes and associated ocular traumas, time of operation, and appropriate operating methods and materials. The authors retrospectively reviewed the charts of 60 patients who underwent repair of lacerated canaliculi from June 1992 to September 1997 at Chonnam University Hospital. Most injuries occurred at second and third decades(30, 50%). The most common cause was fist blow(19, 31.7%). Among a total of 44 patients who could be followed for more than 6 months, 30 of 32 eyes(93.8%) who were repaired with Mini-Monoka and 11 of 12 eyes(91.7%) with bicanalicular stent met with successful results. There were 8 prolapses of tube, 2 granuloma formations, 2 wound infections, one punctal slit, and one canalicular stenosis as the postoperative complication. All of them ware treated successfully. Canaliculoplasty was not successful in cases that operation was performed 48 hours after trauma and the tube was prolapsed within 3 months. No significant associations were found between presence of postoperative epiphora and sex, causes of injury, location of injury and type of canalicular stent. Canaliculoplasty with either Mini-Monoka or bicanalicular stent had successful postoperative outcomes without any significant complications.

BACKGROUND: This is a retrospective, descriptive study, evaluating the observed agreement between 1996 & 2002 Centers for Disease Control and Prevention (CDC) definitions of nosocomial pneumonia (NP) for medical intensive care unit (MICU) and surgical intensive care unit (SICU) patients. METHODS: A total of 476 adult patients who were over 15 years of age and had been admitted to the MICU & SICU of a university hospital between August 1, 2005 and August 1, 2007 were enrolled. Data were collected from electronic medical records according to the 1996 & 2002 CDC definitions of NP. RESULTS: According to the 1996 CDC definitions of NP, there were a total of 116 NP cases and incidence rate was 11.6 per 1,000 patient-days; when analyzed with the 2002 CDC definitions of NP, 75 cases met the criteria and the incidence rate was 7.5 per 1,000 patient-days. Kappa value measuring agreement between the two definitions was 0.67 (95% confidence interval 0.601-0.706). When 1996 CDC definitions were compared with 2002 CDC definitions, sensitivity, specificity, positive predictive value, and negative predictive value were 93.3, 88.5, 60.3, and 98.6%, respectively. CONCLUSION: Even though the aforementioned NP criteria had been applied to the same study population, the number of patients that met the definitions changed depending on which criteria had been used. Therefore, it is necessary to consider the differences when making a comparison.
