Purpose: The purpose of this study was to examine the effect of tooth-brushing oral care on oral health and ventilator-associated pneumonia of patients in Intensive Care Unit (ICU). Methods: A total of 74 participants were recruited from a medical, surgical, or neurosurgical ICU at S Hospital in Seoul, Korea, from September of 2010 to January of 2011. An experimental group (n= 36) received oral care with tooth-brushing while a control group (n=38) received oral care with cotton ball and gauze. In both group, the oral care was done three times a day at least one minute for 7 days. Oral health was examined by the Modified Oral Assessment Guide before the intervention and each night. Results: There is no difference between the groups in aspect of passage of time (p = .603), interaction between time and intervention (p =.300), the performance intervention (p = .766), and the incidence of VAP (p = .486). Conclusion: The effect of oral care with tooth-brushing on oral health and VAP was not different from that of usual oral care in ICU. However, further study is necessary due to high attrition in this study.

MicroRNAs (miRNAs) are small, endogenous RNAs that play important gene-regulatory roles by binding to the imperfectly complementary sequences at the 3'-UTR of mRNAs and directing their gene expression. Here, we first discovered that miR-576-3p was down-regulated in human bladder cancer cell lines compared with the non-malignant cell line. To better characterize the role of miR-576-3p in bladder cancer cells, we over-expressed or down-regulated miR-576-3p in bladder cancer cells by transfecting with chemically synthesized mimic or inhibitor. The overexpression of miR-576-3p remarkably inhibited cell proliferation via G1-phase arrest, and decreased both mRNA and protein levels of cyclin D1 which played a key role in G1/S phase transition. The knock-down of miR-576-3p significantly promoted the proliferation of bladder cancer cells by accelerating the progression of cell cycle and increased the expression of cyclin D1. Moreover, the dual-luciferase reporter assays indicated that miR-576-3p could directly target cyclin D1 through binding its 3'-UTR. All the results demonstrated that miR-576-3p might be a novel suppressor of bladder cancer cell proliferation through targeting cyclin D1.

Recently, interferon gamma releasing assay has been recommended to compensate the tuberculin skin test (TST) for screening for latent tuberculosis infection (LTBI). Although it improved the detection of LTBI before treatment with tumor necrosis factor blocker, its application to immune suppressed patients is limited. We report a case of peritoneal tuberculosis (TB) developed in a patient who tested positive for TST and QuantiFERON-TB Gold (QFT-G) before infliximab therapy, to emphasize the importance of monitoring during treatment. A 52-year-old woman presented with abdominal distension. She had been diagnosed with seropositive rheumatoid arthritis six years ago. She had started taking infliximab six months ago. All screening tests for TB were performed and the results of all were negative. At admission, the results of repeated TST and QFT-G tests were positive. Histopathological examination confirmed peritoneal TB. The patient started anti-TB therapy and the symptoms were relieved.

Objectives: The objective of this study is to review the diagnostic methods of neurologic symptoms by non-organic causes. Methods: We experienced a case of a motor and sensory disturbance patient without abnormal findings in the diagnostic tests. Using this process, we became aware that it is important to remember some of the methods when treating patients who are suspicious of neurologic symptoms by non-organic causes. Results: First, we should perform a variety of diagnostic tests to exclude the organic causes. Second, we should persistently observe a consistency of the patient's symptoms and attitude. Finally, we should perform a neurological examination in order to acquire the objective physical findings. Conclusions: Because there are limitations in the methods above, we have to be aware of making a mistake regarding the disability by organic causes as that by non-organic causes.

Neurolymphomatosis is a complication of lymphoma and initial presentation of cranial nerve involvement has been rarely reported. We describe a patient with neurolymphomatosis who presented as facial palsy mimicking steroid responsive Bell's palsy, a common and benign condition. This case shows that even minor neurologic deficit of lymphoma patient should not be absolutely regarded as a benign condition.

Hyperhomocysteinemia is an independent risk factor for cardiovascular, cerebrovascular and peripheral vascular diseases that are complicated by atherosclerosis and a thromboembolism. An increased level of plasma homocysteine develops from a genetic defect in the of enzyme for the homocysteine metabolism or a vitamin deficiency. Hyperhomocysteinemia has direct toxic effect on the vascular endothelium and causes damages to the antithrombotic action of vascular endothelial cells. Most cases of hyperhomocysteinemia are asymptomatic, but cardiopulmonary or cerebrovascular incidents developin rare cases. In the case of a thromboembolism with an unknown cause, hyperhomocysteinemia should be considered in a differential diagnosis. The authors report a case of pulmonary thromboembolism in a patient with hyperhomocysteinemia with a review of the relevant literature.

Systemic vasculitis involving the lung is a rare manifestation of myelodysplastic syndrome (MDS), and secondary vasculitis is considered to have poor prognosis. A 44-year-old man presented with fever and dyspnea of 1 month duration. A chest radiograph revealed bilateral multiple wedge shaped consolidations. In addition, the results of a percutaneous needle biopsy for non-resolving pneumonia were compatible with pulmonary vasculitis. Bone marrow biopsy was performed due to the persistence of unexplained anemia and the patient was diagnosed with MDS. We reported a case of secondary vasculitis presenting as non-resolving pneumonia, later diagnosed as paraneoplastic syndrome of undiagnosed MDS. The cytopenia and vasculitis improved after a short course of glucocorticoid treatment, and there was no recurrence despite the progression of underlying MDS.

Dermoid cysts are benign congenital tumors composed of keratinizing squamous epithelium and dermal derivatives. They account for less than 1% of all intracranial tumors and are rarely exhibited at the base of the skull. To the best of our knowledge, only one case report has presented computed tomography and conventional T1-weighted magnetic resonance (MR) findings that revealed an infratemporal dermoid cyst. In the present study, we report an unusual case of a dermoid cyst in the right infratemporal fossa, which was incidentally detected by MR imaging with the Dixon technique. This article also highlights the importance of meticulous radiological review and the usefulness of the Dixon technique in everyday clinical practice.

The purpose of this study is to report that a patient suffered from Common Peroneal Neuropathy (CPN) caused by ankle sprain was improved by acupuncture plus electro-acupuncture. In this study, the patient was diagnosed with magnetic resonance image(MRI) and electomyography(EMG). We treated at acupoints ST36, ST41, SP9, GB34, GB39 and LR3 by acupuncture plus electro-acupuncture twice a day for 16 days; a total of 30 times. We used evaluation scale including muscle manual testing(MMT) and visual analogue scale (VAS). MMT changed from Grade 0 to Grade 5 and VAS changed from 10 to 2 after treatment for 16days with hospitalization. Though it is a case report, these results suggest that acupuncture and electrical acupuncture might have valid effect on CPN in controlled environment.

A 21-year-old male was admitted for evaluation of a mass shadow on chest film. On chest computed tomography showed 5 cm sized homogeneous low density based on the second thoracic vertebral body in the posterior mediastinum. The patient had been performed thoracic sympathectomy 6 months before admission and oxidized cellulose was used for hemostasis at that operation. Surgical resection was performed and microscopic result was foreign body granuloma caused by oxidized cellulose. Oxidized cellulose is an absorbable sterile mesh and used to control capillary or venous bleeding. Although the manufacturer recommends its removal after hemostasis is achieved, in clinical practice it is usually left in situ to reabsorb spontaneously, usually with no untoward effect.
