Currently, fixation with "absorbable plates and screws" is widely used for the treatment of facial bone fracture. But it is carefully used for mandible fracture, because it needs much stronger skeletal stability caused by deviation in part of fracture. And there are some complications by using it. We need "absorbable plates and screws" depending on the case of fracture site of mandible and combined fracture. And it was classified favorable or unfavorable fracture according to the aspect of fracture site. In favorable fracture without deviation of symphysis, only "one absorbable plate and screws" has been used, and in unfavorable fracture, we used "two absorbable plates and screws". In the cases of body and angle fracture, "two absorbable plates and screws" have been used because there is more underneath load in body and angle fracture than in symphysis fracture. As this way, we basically used Biosorb FX(R) 2.0 system and applied 21 patients in 34 cases. Finally, we got enough skeletal stability in mandibular fracture and there were not any complications such as malocclusion, ununion and late tissue response. So we report these results along with document consideration.

BACKGROUNDS: Obstructive sleep apnea syndrome(OSA) can divided into two groups, positional (PP) and non-positional(NPP) obstructive sleep apnea syndrome, according to the body position while sleeping. In this study, we evaluated the differences of anthropometirc data and polysomnographic recordings between the two types of sleep apnea syndrome. MATERIALS: Fifty patients with OSA were divided two groups by Cartwright's criteria. The supine respiratory disturbance index (RDI) was at least two times higher than the lateral RDI in the PP group, and the supine RDI was less than twice the lateral RDI in the NPP group. This patients underwent standardized polysomnographic recordings. The anthropometirc data and polysomnographic data were analyzed, statistically. RESULTS: Of all 50 patients, 30% were found to be positional OSA. BMI was significantly higher in the PP group(p<0.05). Total sleep time was significantly longer in the PP group (350.6±46.0min, p<0.05). Sleep efficiency was high in the PP group(89.6± 6.4%, 85.6±9.9%, p<0.05). Deep sleep was significantly higher and light sleep was lower in the PP group than in the NPP group but no difference was observed in REM sleep between the two groups. Apnea index(AI) and RDI were significantly lower(17.0±10.6, 28.5±13.3, p<0.05) and mean arterial oxygen saturation was higher in the PP group(92.7 ±1.8%, p<0.05) than in the NPP group. CONCLUSION: Body position during sleep has a profound effect on the frequency and severity of breathing abnormalities in OSA patients. A polysomnographic evaluation for suspected OSA patients must include monitoring of the body position. Breathing function in OSA patients can be improved by controlling their obesity and through postural therapy.

Purpose: The purpose of this program is to develop an educational program to improve the nursing management competency of middle-level nursing managers. Methods: The program outline is based on the results of the Importance Performance Analysis (IPA) and Systematic Review (SR). Also performed the content validity accordingly. Results: The result of the concepts are derived from 6 competencies for planning process, 4 competencies for organizing process, 4 competencies for staffing process, 26 competencies for directing process, and 12 competencies for controlling process by integrating IPA and SR. This outline of the program was constructed according to the derived integrated concept and both content validity and structured outline were interpreted as valid. Conclusion This suggests that middle-level managers need a systematic program and support to effectively lead the organization by recognizing the importance rather than performance.

BACKGROUND: Green tea extracts are approved as nonprescription drug and available as health functional foods, health foods, and beverages. Clinical information on the products is lacking. METHODS: Information about the products on green tea nonprescription drugs was obtained from the website of the Korea Pharmaceutical Information Center. The Naver, i.e., a top ranking online search portal, was used for compiling the list of the health functional food products using key words of ‘green tea catechin’ on August 23, 2018. The recommended daily dosages of catechins were calculated as 30% of the total dried mass of green tea and about 50% of the catechins were considered as epigallocatechin gallate (EGCG). RESULTS: A total of two types of nonprescription drugs containing green tea powder or extracts, nine health functional food products, and three types of health foods were found. The regulatory requirements of the EGCG exceeding 800 mg were reported to be associated with adverse effects of elevated liver enzyme. If consumers take several green tea products concurrently, such as nonprescription drugs with health functional foods or health foods, it could exceed the recommended amount of EGCG. CONCLUSION: The concurrent use of green tea products as nonprescription drugs, health functional foods, and healthy foods may lead to an increased exposure to EGCG. Pharmacists should be aware the availability of various types of green tea products and the potential risk of liver toxicity due to excessive consumption of EGCG.

We report a case of intravenous infusion amiodarone induced acute hepatitis, occurs within 1 day after initiation of drug in a 72-year-old woman with paroxysmal atrial fibrillation. Liver function test before intravenous infusion amiodarone treatment was normal. She was treated with intravenous infusion amiodarone, and then developed acute hepatitis next day. We suspected drug induced hepatitis due to intravenous infusion amiodarone. The liver function test returned to normal after the amiodarone was stopped. We described an unusual case which intravenous infusion amiodarone induced acute hepatitis within.

Upon contact with airway epithelial cells, mycobacteria activate several signal transduction events that are required for induction of inflammatory cytokines/chemokines. In this study, we found that Mycobacterium tuberculosis (Mtb)induced reactive oxygen species (ROS) production is essential for the expression of tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and CXC-chemokine ligand (CXCL) 8 through the activation of mitogen-activated protein kinases [MAPKs; extracellular signal-regulated kinase (ERK) 1/2 and p38 MAPK] in A549 cells representing alveolar epithelial cells. We observed that Mtb rapidly enhanced ROS production after stimulation in a toll-like receptor (TLR) 2-dependent manner. In addition, Mtb triggered ERK1/2 and p38 MAPK signaling pathways which were dependent on ROS generation in A549 cells. Moreover, Mtb stimulation significantly increased the secretion of TNF-alpha, IL-6, and CXCL8 over that in untreated controls. Pretreatment of A549 cells with the antioxidant, N-acetylcysteine and the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase inhibitor, diphenylene iodonium, substantially inhibited Mtb-induced production of TNF-alpha, IL-6, and CXCL8. Studies using inhibitors selective for ERK1/2 and p38 MAPK pathways showed that both pathways play an essential role in the induction of TNF-alpha, IL-6, and CXCL8 at transcriptional levels in A549 cells. Collectively, our findings indicate the critical role of TLR2-dependent ROS in the Mtb-induced inflammatory cytokine/chemokine production in alveolar epithelial cells through MAPK-dependent signaling pathways.

BACKGROUND: Acne vulgaris is the most common skin disease worldwide, with many available treatment modalities, including oral and topical medications and laser therapy. Recently, a novel device (Isolaz, Pleasanton, CA, USA) that combines vacuum pressure and a broadband light source (400 nm to 1,200 nm) was developed for the treatment of acne. OBJECTIVE: To determine the clinical efficacy and safety of photopneumatic therapy for the treatment of acne vulgaris of the face. METHODS: Twenty adults with mild to moderate facial acne vulgaris received 4 successive treatments on one side of the face with a combined photopneumatic device (intense pulsed light: fluence=5.8 J/cm2; negative pressure=iMP mode) at 2 week intervals. Acne lesions on the opposite side of the face were not treated. Lesion counts were performed at baseline, prior to each treatment session, and at 3 months after the final treatment session. RESULTS: Significant lesion improvements and reduced numbers of acne lesions were observed on the treated side of the faces. Most patients experienced global clinical improvement. No severe side effects occurred during the study, with only a few patients experiencing transient erythema, purpura and/or exacerbation of pre-existing acne. CONCLUSION: Photopneumatic therapy is a safe and effective treatment for mild to moderate acne vulgaris.
