The Diego blood group system consists of two pairs of antigens, Dia and Dib The incidence of Dia is low among pure Caucasian, Blacks, Polynesian and Eskimo, however, the rnongolians and American indians have both Dia and Dib. We report a case of two days old male who was admitted on first day of life for jaundice and subsquently exchange transfusion was performed on second day of life for bilirubin of 20 mg/dl. The blood groups of patient and his mother were both Rh D positive 0 type. Direct and indirect Coombstest were strong positive in the patient and indirect Coombstest was positive in his mother. We found anti-Dib antibody in his rnother's serum. The phenotype of Diego blood group system of the patient and his mother were Di (a+b+) and Di (a+b- ), respectively and hemolytic anemia in this case was due to anti-Dib antibody.

Purpose: This study aimed to identify the mental fitness, perspective taking, attitude toward the elderly, and quantitative encephalogram among caregivers. Methods: In this mixed method research, 14 female caregivers at an elderly care facility in Y city were participated from December 1st to December 31st, 2019. Structured questionnaires were applied to measure general characteristics, mental fitness, perspective taking, and attitude toward the elderly. Brain waves were measured by quantitative encephalogram in the prefrontal lobe. High frequency and high level of care tasks were analyzed using content analysis. Results: According to analysis of brain waves, caregivers experienced high level of physical strain & stress and psychological distraction & stress.Mental fitness (p<.05) and perspective taking (p<.001) were associated with attitude toward the elderly.Moreover, physical strain & stress was associated with psychological distraction & stress (p<.05, p<.001). High frequency and high level tasks were excretion and position change & movement care related tasks, respectively. Conclusion These findings should be consider as an evidence for supporting care tasks based on concrete and objective understanding of caregivers using self-reported index as well as neurophysiological indicators including brain waves.

The aim of this study was to compare the length between the mesio-buccal and mesio-lingual canal of the mandibular molars before and after early coronal flaring at the different measuring time using several electronic apex locators. Fifty mandibular molars with complete apical formation and patent foramens were selected. After establishing the initial working length of the buccal and lingual canal of the mesial root using a surgical microscope (Carl Zeiss Co. Germany) at 25X with #15 K-file tip just visible at the foramen, radiographs were taken for the working length. After measuring the length of mesio-buccal and mesio-lingual canal (control group), the electronic lengths were measured at different times using several electronic apex locators (experimental groups; I-Root ZX, II-Bingo, III-Propex, IV-Diagnostic). After early coronal flaring using the K3 file, the additional electronic lengths were measured using the same manner. The results were as follows: One canal has a correct working length for the mesial root of the mandibular molar, it can be used effectively for measuring the electronic working length of another canal when the files are superimposed or encountered at the apex. In addition, the accuracy of the electronic apex locators was increased as the measurement was accomplished after the early coronal flaring of the root canal and the measuring time was repeated.

Fahr's disease (FD) is a rare neurologic disorder characterized by the symmetric and bilateral intracerebral calcification in a patient. We describe the case of a 65-year-old woman who presented with gait disturbance, abnormal mentality, and visual field defect. The result of a brain computerized tomography showed spontaneous intracranial hemorrhage in the right parieto-occipital area, and also showed the incidence of symmetric and bilateral intracerebral calcification. Moreover, laboratory studies indicated characteristic hypoparathyroidism. This brings us to understand that additionally, one of her sons also presented with similar intracerebral calcification, and was subsequently diagnosed with FD. Thus, her case was consistent with that of a patient experiencing FD. The patient had hypertension, which we now know might have caused the intracerebral hemorrhage. However, this patient's brain lesions were in uncommon locations for spontaneous intracerebral hemorrhage, and the lesions were noted as occurring away from the identified heavily calcified areas. Thus, it seemed that the massive calcification of cerebral vessels in the basal ganglia, the most common site of intracerebral hemorrhage, might have prevented a hypertensive intracerebral hemorrhage. Eventually, an intracerebral hemorrhage occurred in an uncommon location in the patient's brain.

Purpose: This study aimed to measure COVID-19 stress and the quantitative electroencephalography (QEEG) stress quotient and identify the coping styles of face-to-face service industry employees during the COVID-19 pandemic. Methods: This cross-sectional study administered structured questionnaires consisting of sections on general characteristics, COVID-19 stress, and coping style for stress to 21 face-to-face service industry employees between April 1 and April 18, 2021. The physical tension & stress quotient and psychological distraction & stress quotient were measured in the prefrontal lobe with QEEG. Results: Emotional easiness (r=.62, p=.002) and escape-avoidance (r=.55, p=.009) as a passive coping style were associated with COVID-19 stress, and seeking social support as an active coping style was associated with the left physical tension & stress quotient (r=.47, p=.031). Conclusion These findings provide evidence regarding the objective status of the mental health of face-to-face service industry employees using both a self-reported scale and neuroscientific indicators, including brain quotients.

PURPOSE: We created an 'AAPM TG18 Evaluation Tool' and we determined its usefulness for the quality control of a diagnostic monitor. MATERIALS AND METHODS: We created an evaluation tool (the AAPM TG18) for conducting quality control of a diagnostic monitor, and we evaluated the measurement items of the AAPM TG18 evaluation tool. The measurement items were geometric distortion, fixed quantity assessment and visual assessment of the veiling glare, and we carried out adjustment for the luminance meter 0% calibration, which was used to revise the diagnostic monitor DICOM LUT. RESULTS: With the AAPM TG18 Evaluation Tool, we measured the 2-dimensional length when evaluating the quantitative geometric distortions in the TG18-QC test pattern, and we measured the veiling-glare ring response function, which provided information regarding the spatial extent of the luminance spread, and this measurement of the can be performed using the TG18-GV pattern. Additionally, the AAPM TG18 Evaluation Tool can be used for sensor calibration to standardize the basic rate of 0% luminance when performing periodic calibration. CONCLUSION: The evaluation tool is a very useful for easily evaluating many of the examination items of the AAPM TG18 for performing quality control of a diagnostic monitor.

OBJECTIVE: With improved technology, the values of intraoperative computed tomography (iCT) have been reevaluated. We describe our early clinical experience with a mobile CT (mCT) system for iCT and discuss its clinical applications, advantages and limitations. METHODS: Compared with intraoperative magnetic resonance imaging, this mCT system has no need for major reconstruction of a preexisting operating room for shielding, or for specialized instruments or equipment. Patients are placed on a radiolucent head clamp that fits within the gantry. Because it consists simply of a scanner and a workstation, it can be moved between locations such as an operating room, an intensive care unit (ICU) or an emergency room without difficulty. Furthermore, it can achieve nearly all types of CT scanning procedures such as enhancement, temporal bone imaging, angiography and three-dimensional reconstruction. RESULTS: For intracranial surgery, mCT can be used for intraoperative real-time neuronavigation by interacting with preoperative images. It can also be used for intraoperative confirmation of the extent of resection of intracranial lesions and for immediate checks for preventing intraoperative unexpected accidents. Therefore, the goals of maximal resection or optimal treatment can be achieved without any guesswork. Furthermore, mCT can achieve improved patient care with safety and faster diagnosis for patients in an ICU who might be subjected to a ventilator and/or various monitoring devices. CONCLUSION: Our initial experience demonstrates that mCT with high-quality imaging offers very useful information in various clinical situations.

BACKGROUND: The relationship between viral hepatitis and lichen planus (LP) remains as a matter of controversy. Geographical variations are suggested to be a major factor influencing such association. Reliable figures from Korean patients are still lacking. OBJECTIVE: The aim of this study is to determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in Korean patients with lichen planus (LP) and to compare it with patients without LP. METHODS: The retrospective study was performed on 45 LP patients and 45 controls with matching age and gender. We examined for serological evidences of hepatic disease, hepatitis B surface antigen (HBsAg), and anti-HCV seropositivity. Statistical analysis was calculated by using an unpaired t-test and Fisher's exact test. RESULTS: No significant differences between the serum levels of alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were observed between the two groups. The prevalence of HBsAg in LP patients (4.4%) was not significantly higher (p>0.05) than those of the control subjects (2.2%). None of the patients with LP nor the control subjects had Anti-HCV. CONCLUSION: Korean patients with LP did not have any significant associations with liver diseases or HBV, and HCV infections. Although a large-scale multicenter study is needed to support our results, it is not advisable for Korean patients with LP to be tested for liver functions or HBV, and HCV infections as part of a routine screening test.
