BACKGROUND: Korea is expected to become an ultra-aged society, in which the elderly population will account for more than 20% of the total population, after 2025. Thus, the social costs due to osteoporotic fractures are expected to increase. Therefore, this study aimed to measure disability weights (DWs) of osteoporosis and osteoporotic fractures in Korea. METHODS: The scenarios were developed to standardize the severity of 6 health statuses: osteoporosis and osteoporotic fractures including wrist, hip, post-hip, vertebral, and post-vertebral fracture. The values for these 6 health statuses were sought via a person trade-off (PTO) approach. We measured the value by PTO and we calculated it to DW of 6 health statuses. Three clinical expertise panels of 33 experts were established, and face-to-face interviews were conducted from July to December 2017. RESULTS: The distribution of DW varied by panel. DWs ranged from 0.5 (Osteoporosis) to 0.857 (Hip fracture) for Panel 1, 0.091 (Osteoporosis) to 0.5 (Hip fracture) for Panel 2, and 0.091 (Osteoporosis) to 0.726 (Hip fracture) for Panel 3. The final values for the 6 health statuses obtained by pooling all data from 3 panels ranged from 0.286 (Osteoporosis) to 0.750 (Hip fracture). There was no significant difference in rankings for the 6 health statuses among the 3 panels. CONCLUSIONS: Comparing the DW of osteoporotic fracture in this study with other diseases in previous studies, it is predicted that osteoporotic fractures, especially hip fractures, will have a considerable burden of disease.

Pneumatosis intestinalis is an uncommon condition that is characterized by the presence of gas within the bowel wall. We experienced a case of pneumatosis intestinalis after cession of chemotherapy and we herein report on this case. A 58-year old man was admitted to our hospital for the evaluation of incidentally recognized pneumatosis intestinalis. He was diagnosed as having non small cell lung cancer in August 2006 and he received radiation therapy for concomitant brain metastasis and SVC syndrome in September 2006. He achieved a partial response after completing 6 cycles of chemotherapy with gemcitabine and cisplatin. Newly enlarged lymph nodes were observed on the follow-up CT, and chemotherapy with paclitaxel and carboplatin was started in July 2007. Due to the lack of a response, the therapeutic regimen was switched to oral erlotinib. After 1 month of treatment, the follow-up CT for response evaluation revealed pneumatosis intestinalis in the ascending colon without any subjective symptoms such as fever or abdominal pain. The laboratory results were within the normal range except for a slight increase of leukocytes. He underwent right hemicolectomy, but he didn't survive his postoperative acute renal failure and pneumonia

Metronidazole is an antimicrobial agent widely used for the treatment of trichomoniasis, giardiasis, amebiasis, and anaerobic bacterial infections. It has been reported that metronidazole-induced neurotoxicity is associated with responsible lesions on brain MRI. We report 2 patients with metronidazole-induced neurotoxicity, who had no responsible lesions on brain MRI for their neurological deficits. The pathogenic mechanisms are discussed.

As one of trials on neuroprotection after spinal cord injury, we used pregabalin. After spinal cord injury (SCI) in rats using contusion model, we observed the effect of pregabalin compared to that of the control and the methylprednisolone treated rats. We observed locomotor improvement of paralyzed hindlimb and body weight changes for clinical evaluation and caspase-3, bcl-2, and p38 MAPK expressions using western blotting. On histopathological analysis, we also evaluated reactive proliferation of glial cells. We were able to observe pregabalin's effectiveness as a neuroprotector after SCI in terms of the clinical indicators and the laboratory findings. The caspase-3 and phosphorylated p38 MAPK expressions of the pregabalin group were lower than those of the control group (statistically significant with caspase-3). Bcl-2 showed no significant difference between the control group and the treated groups. On the histopathological analysis, pregabalin treatment demonstrated less proliferation of the microglia and astrocytes. With this animal study, we were able to demonstrate reproducible results of pregabalin's neuroprotection effect. Diminished production of caspase-3 and phosphorylated p38 MAPK and as well as decreased proliferation of astrocytes were seen with the administration of pregabalin. This influence on spinal cord injury might be a possible approach for achieving neuroprotection following central nervous system trauma including spinal cord injury.

Background/Aims: We explored whether high sodium intake, assessed by urinary excretion, determines the risk of sarcopenia and nonalcoholic fatty liver disease (NAFLD). Methods: We analyzed 10,036 adult participants with normal kidney function from the Korea National Health and Nutrition Examination Survey (2008–2011). NAFLD was identified using the fatty liver index, and the muscle mass was evaluated using dual X-ray absorptiometry. The dietary sodium intake was estimated using Tanaka’s equation. Results: The mean 24-hour urinary sodium excretion was 144.2±36.1 mmol/day (corresponding to 3.3 g/day Na) in the total population. The 24-hour urinary sodium excretion showed moderate accuracy in predicting NAFLD (area under the receiver operating characteristic, 0.702; 95% confidence interval [CI], 0.692 to 0.712). A cutoff value of 99.96 mmol/day (corresponding to 2.30 g/day Na) for urinary sodium excretion in predicting NAFLD showed 76.1% sensitivity and 56.1% specificity. The results of multiple adjusted models indicated that the participants with the highest urinary sodium excretion had a significantly higher risk of NAFLD (odds ratio, 1.46; 95% CI, 1.27 to 1.66; p<0.001) and sarcopenia (odds ratio, 1.49; 95% CI, 1.28 to 1.73; p<0.001) than those with the lowest urinary sodium excretion. The association between a higher 24-hour urinary sodium excretion and NAFLD was independent of sarcopenia. Conclusions Participants with a high sodium intake, as assessed by sodium excretion, had a substantial risk of NAFLD and sarcopenia

BACKGROUND: Epigenetic alterations in certain genes are now known as at least important as genetic mutation in pathogenesis of cancer. Especially abnormal hypermethylation in or near promoter region of tumor suppressor genes (TSGs) are known to result in gene silencing and loss of gene function eventually. The authors tried to search for new lung cancer-specific TSGs which have CpG islands and HpaII sites, and are thought to be involved in carcinogenesis by epigenetic mechanism. METHODS: Tumor tissue and corresponding adjacent normal tissue were obtained from 10 patients who diagnosed with non small cell lung cancer (NSCLC) and underwent surgery in Konyang university hospital in 2005. Methylation profiles of promoter region of 21 genes in tumor tissue & non-tumor tissue were examined with HpaII-MspI methylation microarray (Methyl-Scan DNA chip(R), Genomic tree, Inc, South Korea). The rates of hypermethylation were compared in tumor and non-tumor group, and as a normal control, we obtained lung tissue from two young patients with pneumothorax during bullectomies, methylation profiles were examined in the same way. RESULTS: Among the 21 genes, 10 genes were commonly methylated in tumor, non-tumor, and control group. The 6 genes of APC, AR, RAR-b, HTR1B, EPHA3, and CFTR, among the rest of 11 genes were not methylated in control, and more frequently hypermethylated in tumor tissue than non-tumor tissue. CONCLUSION: In the present study, HTR1B, EPHA3, and CFTR are suggested as possible novel TSGs of NSCLC by epigenetic mechanism.

With the progress of computed tomography (CT), the detection of small pulmonary nodules has been increased. The conventional diagnostic modalities for tissue confirmation, such as bronchoscopic biopsy or transthoracic needle biopsy, may not be successful in some cases. Too small a nodule or the nodules located far from the pleural surface can be marked and localized with device preoperatively and then this tissue can be obtained surgically. CT-guided hook wire fixation is useful in marking pulmonary nodules and there are few complications with this procedure. We report here on a case of double primary lung cancer that was diagnosed by percutaneous localization with using a hook wire

A small localized infarction in the dorsal pontine area can cause various eye-movement disturbances, such as abducens palsy, horizontal conjugate gaze palsy, internuclear ophthalmoplegia, and one-and-a-half syndrome. However, complete loss of vertical saccades and pursuit with horizontal gaze palsy has not been reported previously in a patient with a small pontine lesion. We report a 67-year-old man with a small dorsal caudal pontine infarct who exhibited total horizontal gaze palsy as well as loss of vertical saccades and pursuit.

A 39-year-old woman presented with symptoms of dyspnea. Ten years previously, she had received a tracheostomy because of the decision to not continue taking an anticonvulsant drug. Presently, chest computed tomography showed diffuse stenosis and focal web at the cervical trachea. We performed bronchoscopy and found a two-thirds reduction of the upper trachea due to the web-like fibrotic stenosis. Papillotome electrocautery removed the stenotic lesion. Endobronchial electrocautery is a valuable tool with potential for therapy of an endobronchial obstructing airway lesion. We report this case to introduce the successful treatment with papillotome electrocautery.
