Objectives:
Dental caries and periodontal disease are infectious and chronic diseases. The aim of the study was to investigate the antimicrobial effect of mentha extracts against Streptococcus mutans (S. mutans ) and Porphyromonas gingivalis (P. gingivalis ).
Methods:
This activity of mentha extracts were confirmed by the disk diffusion test and minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and colony forming unit (CFU) assays.
Results:
S. mutans and P. gingivalis showed the highest antimicrobial activity within the inhibition zones. The antimicrobial activity was interrupted as the MIC and MBC of the herbal extracts against the two bacteria were 1 mg/ml and 10 mg/ml, respectively. The antimicrobial effect was determined by the CFU assay.
Conclusions
Mentha herb extract demonstrated potential antimicrobial activity against S. mutans and P. gingivalis that cause dental caries and periodontal disease.

PURPOSE: This study aimed to identify multidimensional factors influencing burnout in intensive care unit(ICU) nurses. METHODS: A descriptive cross-sectional design was used. Data were collected during February 2016 from a convenience sample of 222 tertiary hospital ICU nurses and analyzed using t-test, ANOVA, correlation analysis, and multiple regression analysis. RESULTS: Burnout correlated positively with compassion fatigue (CF)(r=.37, p < .001), and negatively with compassion satisfaction (CS)(r=-.66, p < .001). The regression model explained 57% of the variance in burnout. For individual characteristics in the model, perceived health status (β=-.27, p < .001) and gender (β=.14, p=.028) were the most influential factors for ICU nurses' burnout. In the model with added work-related characteristics, nursing environment (β=-.22, p=.001), perceived health status (β=-.20, p=.001), and satisfaction with department (β=-.19, p=.007) were the most influential factors. Finally, for the model with psychological characteristics added, CS (β=-.56, p < .001) and CF (β=.35, p < .001) were the most influential factors. CONCLUSION: Results reveal that most ICU nurses have a moderate level of CF and a moderate to high level of CS and burnout, and that individual, work-related and psychological factors are relevant in ICU nurses' burnout. Programs or interventions to reduce burnout should be developed taking into account these multidimensional factors.

Using 3D ultrasound, bilateral chylothorax was diagnosed antenatally in the second trimester. Apparently stable, bilateral pleural effusion progressed rapidly to severe hydrops with facial edema during observation, and then we decided bilateral pleural-amniotic shunt operation. Here we present a case where drainage of pleural effusion by a double reverse pig tail stent made by ourself was achieved, although placement of the thoracoamniotic shunt resulted in near complete drainage of bilateral pleural effusion with normalization of intrathoracic anatomic relationships, subsequent resolution of fetal hydrops, but the ultimate outcome was unsuccessful due to the internalization of one catheter and unknown sudden death. We think that ongoing research is required to further evaluation about complications associated with this procedure, specifically failure of function due to obstruction, migration of the catheter,

A 53-year-old woman presented with left mandibular area pain, trismus, and facial numbness that had persisted for 4 years. Physical examination revealed a 3x5 cm, hard, non-tender, and round mass on the left mandibular area. Computed tomography and magnetic resonance imaging revealed an expansile tumor involving the left mandibular ramus and temporomandibular joint area with bone destruction, extending to the base of middle cranial fossa and left zygomatic bone. The mass at the segment of left mandible and zygomatic bone, and base of middle cranial fossa was removed. Pathological examination of the mass revealed a giant cell tumor. The defect was reconstructed with iliac bone for the mandible and temporal bone and fascia for the cranial bone and dura. The case is described along with a review of the literature.

We present an unusual case in which a patient was diagnosed with the preeclampsia associated with a partial hydatidiform mole and bilateral theca-lutein cysts. The patient newly developed proteinuric hypertension at 16 weeks' gestation. Ultrasound findings showed small multiple cystic spaces in the placenta and a live singleton fetus. Triploid 69, XXX was confirmed at karyotype analysis. Intrauterine fetal death was found at 18 weeks' gestation and termination of pregnancy was performed, and a partial hydatidiform mole was confirmed at pathologic examination. Torsion of bilateral theca-lutein cysts was developed at postpartum one week. Detorsion and aspiration of the bilateral theca-lutein cysts were performed under the laparoscopy.

BACKGROUND: The purpose of this study was to determine whether the injection rate affects the spread of spinal anesthesia in cesarean sections. METHODS: Spinal anesthesia was performed on 45 parturients in a cesaren section. Dural puncture was performed in the sitting position with a 27-gauge Whitacre needle. All patients received a mixture of 10 mg hyperbaric bupivacaine and 15 microgram fentanyl. Twenty five (Group I) patients received rapid injections (about 0.2-0.3 ml/sec) and twenty (Group II) received slow injections (about 0.1 ml/sec). Anesthetic levels, time to T4 sensory block, maximal height sensory block and incidence of hypotension were measured. RESULTS: There was significantly rapid T4 sensory block in group I but no differences in maximal height of sensory block and incidence of hypotension between the two groups. CONCLSIONS: We conclude that injection rate (about 0.1-0.3 ml/sec) has a statistically insignificant influence on the maximal height sensory block and incidence of hypotension.

OBJECTIVE: To determine which compartments of placenta in the term pregnancy express the embryonic stem cell markers. METHODS: We have used immunohistochemical methods with antibodies to embryonic stem cell surface antigens, TRA 1-60 (Tumor rejection antigen 1-60), TRA 1-81 (Tumor rejection antigen 1-81), SSEA-3 (stage-specific embryonic antigen-3) and SSEA-4 (stage-specific embryonic antigen-4), to identify and localize stem cells in the term placenta. RESULTS: Stem cell marker-positive cells were found in all layer of placenta. Amnionic epithelial cells was immunoreactive with TRA 1-60, TRA 1-81. Amnionic mesenchymal stromal cells was immunoreactive with TRA 1-81. Chorionic mesenchymal stromal cells was immunoreactive with TRA 1-60 and TRA 1-81. SSEA-3 and SSEA-4 were not stained at any compartment of the term placenta. Compartment that was stained most strongly by TRA 1-60 was the amnionic epithelial cells layer. Compartment that was stained most strongly by TRA 1-81 was the chorionic mesenchymal stromal cells layer. CONCLUSION: The mesenchymal stroma cells of the amnion and chorion as well as amnionic epithelial cells may be useful source of pluripotent stem cells in the term placenta.

PURPOSE:
This study was a systematic review and meta-analysis to explore the factors related to quality of life in heart transplant recipients.
METHODS:
To identify studies that suggested the factors related to the quality of life in heart transplant recipients, we searched the articles published from 1974 to November 2018 using Six databases, PubMed, CINAHL, EMBASE, Cochrane, KMBASE and RISS. A total of 22 studies were selected out of 5,234 for the systematic review and meta-analysis on the basis of the PRISMA flow. The quality of study was assessed by assessment tool form the NIH and meta-analysis was performed using the ‘R 3.5.2’ version to analyze the correlated effect sizes.
RESULTS:
Factors related to quality of life in heart transplant recipients were categorized into six domains based on the health-related quality of life model introduced by Ferrans: individual, environmental, biological function, symptoms, functional status, and general health perception. In the meta-analysis, 34 factors were used and 17 factors having significant effect sizes were as follows: self-efficacy, demoralization, perceived control, current occupational status, age, marital status, health promotion life style in the individual characteristics; stress in environmental characteristics; physical function status, creatinine level, left ventricular ejection fraction (LVEF) in biological function; anxiety, depression, symptom frequency and distress in symptoms domain; coping, self-care compliance in functional status.
CONCLUSION
The findings indicate that the multi-dimensional factors influencing the quality of life in heart transplant recipients and provide the evidence for developing effective interventions for improving the quality of life of recipients.

Otosclerosis is a localized disorder of bone metabolism involving the endochondral bone of the otic and labyrinthine capsule. Both "advanced" and "very advanced" otosclerosis refer to the state of otosclerotic involvement of the otic capsule, which has progressed to result in profound deafness with undetectable bone and air conduction thresholds. Shea et al. estimated that 1.6% of patients with otosclerosis had developed profound hearing losses, and that hearing improvements after stapes surgeries in these patients were lower than the case of "not-advanced" otosclerosis. Stapedectomy and hearing aid amplification could be tried, but cochlear implantation is an established intervention for patients with profound sensorineural hearing loss due to otosclerosis. Although the reported results of cochlear implantations in otosclerosis patients are not significantly different from those of other cochlear implantees not affected by otosclerosis, in former conditions, potential ossification of cochlea, facial nerve stimulation, and instability of the results might take place. We report a case of otosclerosis histologically diagnosed for the first time here in Korea, and for which cochlear implantation was successfully performed.

Objectives:
The effectiveness of drugs currently used in medication, which is important in the treatment of alcohol use disorders, is limited. Recently, ondansetron which acts as 5-HT3 receptor antagonist, has been studied and proved possibility as new medication for alcohol use disorder. Meanwhile, there are studies supporting that 5-HT1A receptors are related to addictive behavior. Considering those studies, we expect that vortioxetine, which acts as both 5-HT3 receptor antagonist and 5-HT1A receptor agonist, may be effective in treatment of alcohol use disorder. The purpose of this study is to examine the effect of vortioxetine on alcohol intake of C57BL/6 mice.
Methods:
In this study C57BL/6 mice were randomly assigned to normal saline group, vortioxetine 10 mg/kg group and vortioxetine 1 mg/kg group. To study effect of vortioxetine on alcohol, water, food intake and body weight of mice, we administered each medication for 14 days.
Results:
The overall alcohol intake was different between the three groups (PGroup=0.021), and alcohol intake in vortioxetine 10 mg/kg group was significantly lower than one in placebo group. Change across time points (PTime<0.001) and the interaction between group and time (PGroup×Time =0.016) were also significant. However, there were no significant differences between the three groups in water, food intake and body weight.
Conclusions
These results indicated that administration of high dose vortioxetine reduced alcohol intake of mice.Therefore, it is necessary to conduct clinical studies to examine the effectiveness of vortioxetine as a new treatment for alcohol use disorder.
