PURPOSE: Combined chemoradiotherapy is standard management for locally advanced non-small cell lung cancer (LA-NSCLC), but standard treatment for elderly patients with LA-NSCLC has not been confirmed yet. We evaluated the feasibility and efficacy of concurrent chemoradiotherapy (CCRT) for elderly patients with LA-NSCLC. MATERIALS AND METHODS: Among patients older than 65 years with LA-NSCLC, 36 patients, who underwent CCRT were retrospectively analyzed. Chemotherapy was administered 3-5 times with 4 weeks interval during radiotherapy. Thoracic radiotherapy was delivered to the primary mass and regional lymph nodes. Total dose of 54-59.4 Gy (median, 59.4 Gy) in daily 1.8 Gy fractions and 5 fractions per week. RESULTS: Regarding the response to treatment, complete response, partial response, and no response were shown in 16.7%, 66.7%, and 13.9%, respectively. The 1- and 2-year overall survival (OS) rates were 58.2% and 31.2%, respectively, and the median survival was 15 months. The 1- and 2-year progression-free survivals (PFS) were 41.2% and 19.5%, respectively, and the median PFS was 10 months. Regarding to the toxicity developed after CCRT, pneumonitis and esophagitis with grade 3 or higher were observed in 13.9% (5 patients) and 11.1% (4 patients), respectively. Treatment-related death was not observed. CONCLUSION: The treatment-related toxicity as esophagitis and pneumonitis were noticeably lower when was compared with the previously reported results, and the survival rate was higher than radiotherapy alone. The results indicate that CCRT is an effective in terms of survival and treatment related toxicity for elderly patients over 65 years old with LA-NSCLC.

BACKGROUND: A central venous catheter (CVC) is commonly used for administering chemotherapy to cancer patients. The institutional guideline of the Gyeongsang National University Hospital (GNUH) for blood culture analysis of indwelling CVC patients recommended 6 sets (2 from the periphery and 4 from each lumen). We analyzed the usefulness of this guideline, because complying with this recommendation requires an abundant amount of the sample and it is both inconvenient and expensive. METHODS: Adult patients (age: > or =18 yr old) who were admitted to the cancer center of GNUH between January 2011 and April 2012 were requested to have their blood culture analysis done. The positive rate, contamination rate, and distribution of microorganisms were compared according to the number of requested sets. The positive results of the stipulated 6 sets were analyzed. RESULTS: A total of 5,263 blood cultures were analyzed during the study period; of them, 74.4% were requests of 2 sets and 20.0% were requests of 6 sets. The positive rates in 2 set requests and 6 set requests were 8.0% and 14.3%, respectively (P<0.001). The requests for 6 sets were repeated about 5 times. All 6 sets showed positive in 16 cases (9.1%), whereas a part of the 6 sets was positive in 18 cases (10.3%). CONCLUSIONS: Although the positive rate was relatively high in the 6 set-requested groups, they had to be repeatedly requested. Microbial growth in a part of the 6-set requests was observed in a very small proportion (10.3%) of the patients, indicating that the benefit of blood culture of 6 sets is very low.

PURPOSE: The objective of our study was to compare preoperative "Monitor Templating" with postoperative results for total hip replacement and to investigate the accuracy of "Monitor Templating" that was carried out by monitoring with picture archiving communication system (PACS). MATERIALS AND METHODS: Forty five patients underwent primary cementless total hip replacements. For setting parameters, we located the 10cm rod placed in the medial thigh on anteroposterior view of both hips and in the anterior thigh on Lowenstein lateral view. We measured implant sizes and the predictive value of corrective change in leg length and horizontal offset, by using radiographs magnified 120% of the anteroposterior views of both hips and Lowenstein lateral view of PACS on 27 inch monitor. We examined the correlation between preoperative monitor templating and the actual implant size, postoperative leg length and horizontal offset difference. RESULTS: The preoperative monitor templating showed a high rate of coincidence with the actual implant size, the postoperative leg length, and the horizontal offset difference. The averages in accurate prediction were 98% in the acetabular cup, 98% in the femoral stem, 97% in the postoperative actual difference of leg length, and 97% in the horizontal offset. With regard to leg length discrepancy, the sick limb was on average 4.7 mm shorter and 0.5 mm longer postoperatively than the contralateral limb. The average ratio of horizontal offset of the sick limb to the contralateral limb was 94.6% preoperatively and increased to 97.8% postoperatively. CONCLUSION: Preoperative "Monitor Templating" using PACS images on 26 inch monitor is an easy and effective method for predicting implant size, correcting leg length discrepancy and restoring horizontal offset.

Terminal cancer pain is always a challenge to pain doctors.If the focus of the cancer pain is located in the restricted area, it is easy to control the pain. However, if the focus of cancer pain is widespread, it is very difficult to control the pain and it makes pain doctors embarrassed.Nowadays, the ultrasound-guided nerve block become a popular method. It is easy to find the nerve and helps to insert the catheter around the nerve for the continuous nerve block. We encountered a patient who was 59 years old with a stomach cancer and vertebral metastasis. He complained about the pain in his abdomen, back and left thigh. His abdominal and back pain vanished with the use of continuous lumbar epidural injection. However, the patient still complained about the pain and numbness on the left thigh, because of this, he couldn't get any sleep.We tried a continuous femoral nerve block under the ultrasound guidance, after that his pain was gone.The ultrasound-guided nerve block will be very helpful to control the pain.

OBJECTIVES: Obsessive-compulsive disorder (OCD) is highly prevalent in schizophrenia. And it has been suggested that schizophrenic patients with OCD have longer hospitalization, lower employment rate, and more severe psychopathology compared to those without OCD. The present study aimed to evaluate (1) the prevalence of OCD in subjects with schizophrenia, (2) the prognosis in schizophrenia with OCD, (3) the characteristics of OC symptoms, (4) the change of OC symptoms with selective serotonin reuptake inhibitor (SSRI) use. METHODS: We reviewed the medical records of 63 patients with schizophrenia and classified patients according to the existence of OC symptoms. And we evaluated the clinical and demographic data in 12 schizophrenic patients with OC symptoms and 51 schizophrenic patients without OC symptoms. RESULTS: Schizophrenic patients with OCD had more severe psychopathology (higher CGI) and poorer social functioning (lower GAF) than those without OCD. Social functoning estimated by the rate of employment showed near-significant differences between the two groups and the number of hospitalization was not significantly different. SSRI improved the OC symptoms in seven (70%) of the 10 SSRI users. CONCLUSION: Schizophrenic patients with OC symptoms had severe psychopathlogy and low social adaptation and needed antiobsessional therapy.

BACKGROUND/OBJECTIVE: Oxidative stress plays a key role in neuronal cell damage, which is associated with neurodegenerative disease. The aim of present study was to investigate the neuroprotective effects of perilla oil (PO) and its active component, alpha-linolenic acid (ALA), against hydrogen peroxide (H₂O₂)-induced oxidative stress in SH-SY5Y neuronal cells. MATERIALS/METHODS: The SH-SY5Y human neuroblastoma cells exposed to 250 µM H₂O₂ for 24 h were treated with different concentrations of PO (25, 125, 250 and 500 µg/mL) and its major fatty acid, ALA (1, 2.5, 5 and 25 µ/mL). We examined the effects of PO and ALA on H₂O₂-induced cell viability, lactate dehydrogenase (LDH) release, and nuclear condensation. Moreover, we determined whether PO and ALA regulated the apoptosis-related protein expressions, such as cleaved-poly ADP ribose polymerase (PARP), cleaved caspase-9 and -3, BCL-2 and BAX. RESULTS: Treatment of H₂O₂ resulted in decreased cell viability, increased LDH release, and increase in the nuclei condensation as indicated by Hoechst 33342 staining. However, PO and ALA treatment significantly attenuated the neuronal cell death, indicating that PO and ALA potently blocked the H₂O₂-induced neuronal apoptosis. Furthermore, cleaved-PARP, cleaved caspase-9 and -3 activations were significantly decreased in the presence of PO and ALA, and the H₂O₂-mediated up-regulated BAX/BCL-2 ratio was blocked after treatment with PO and ALA. CONCLUSIONS: PO and its main fatty acid, ALA, exerted the protective activity from neuronal oxidative stress induced by H₂O₂. They regulated apoptotic pathway in neuronal cell death by alleviation of BAX/BCL-2 ratio, and down-regulation of cleaved-PARP and cleaved caspase-9 and -3. Although further studies are required to verify the protective mechanisms of PO and ALA from neuronal damage, PO and ALA are the promising agent against oxidative stress-induced apoptotic neuronal cell death.

BACKGROUND/OBJECTIVES: The accumulation of amyloid-β (Aβ) in the brain is a hallmark of Alzheimer's disease (AD) and plays a key role in cognitive dysfunction. Perilla frutescens var. japonica extract (PFE) and its major compound, rosmarinic acid (RA), have shown antioxidant and anti-inflammatory activities. We investigated whether administration of PFE and RA contributes to cognitive improvement in an Aβ25-35-injected mouse model. MATERIALS/METHODS: Male ICR mice were intracerebroventricularly injected with aggregated Aβ25-35 to induce AD. Aβ25-35-injected mice were fed PFE (50 mg/kg/day) or RA (0.25 mg/kg/day) for 14 days and examined for learning and memory ability through the T-maze, object recognition, and Morris water maze test. RESULTS: Our present study demonstrated that PFE and RA administration significantly enhanced cognition function and object discrimination, which were impaired by Aβ25-35, in the T-maze and object recognition tests, respectively. In addition, oral administration of PFE and RA decreased the time to reach the platform and increased the number of crossings over the removed platform when compared with the Aβ25-35-induced control group in the Morris water maze test. Furthermore, PFE and RA significantly decreased the levels of nitric oxide (NO) and malondialdehyde (MDA) in the brain, kidney, and liver. In particular, PFE markedly attenuated oxidative stress by inhibiting production of NO and MDA in the Aβ25-35-injected mouse brain. CONCLUSIONS: These results suggest that PFE and its active compound RA have beneficial effects on cognitive improvement and may help prevent AD induced by Aβ.

OBJECTIVE: The sacral insufficiency fractures (SIFs) are not uncommon and usually occur in osteoporotic bone with minimal or unremembered trauma. Especially, if they are accompanied by osteoporotic compression fracture of the thoracolumbar spine, SIFs can be usually overlooked due to subtle clinical symptoms and signs coupled with radiographic findings. The review aims to be raising awareness of the incidence & risk factors of the SIFs. METHODS: We retrospectively reviewed the 252 patients who were admitted at our hospital due to osteoporotic compression fracture of the thoracolumbar spine with minimal or unremembered trauma for 5 years. We assessed the incidence of the SIF being accompanied by osteoporotic compression fracture of the thoracolumbar spine and the effects according to sex, age, probable risk factors (diabetes mellitus & arterial hypertension), the location of fracture and the severity of osteoporosis. RESULTS: 252 patients, including 36 men (14.3%) and 216 women (85.7%) were involved in this study and the osteoporotic compression fractures were located at thoracic (36 cases), thoracolumbar junction (180 cases), lumbar spine (36 cases). There are 18 cases (the incidence: 7.1%), including 2 men (5.5%) and 16 women (7.4%) in which the SIF was accompanied by osteoporotic compression fracture of the thoracolumbar spine. The effects according to sex, age, probable risk factors, the location of fracture and the severity of osteoporosis were not statistically different in both groups (group with SIF and group without SIF). CONCLUSION:The clinicians need to consider the possibility of SIF in patients of osteoporotic compression fracture of the thoracolumbar spine.
