In January 2020, COVID19 plunged the whole planet into a pandemic. This has caused great economic losses and is causing social confusion. COVID19 has a superior infection rate among people with underlying disease such as heart disease, high blood pressure, diabetes, stroke, depression, and cancer. In addition, it was studied that patients with underlying disease had a higher fatality rate than those without underlying disease. In this study, the presence or absence of underlying disease was classified using EEG data. The data used to classify the presence or absence of underlying disease was EEG data provided by Data Science lab, consisting of 33 features and 69 samples. Z-score was used for data pretreatment. Classification was performed using the neural network NEWFM and ZNN engine. As a result of the classification of the presence or absence of the underlying disease, the experimental results were 77.945 for NEWFM and 76.4% for ZNN. Through this study, it is expected that EEG data can be measured, the presence or absence of an underlying disease is classified, and those with a high infection rate can be prevented from COVID19. Based on this, there is a need for research that can subdivide underlying disease in the future and research on the effects of each underlying disease on infectious disease.

It has been found that the incidence and mortality of COVID-19 are high in patients with underlying chronic diseases. Amid COVID-19 pandemic, tooth brushing is as important as hand washing for health care. The aim of this study was to identify factors related to the rate of tooth brushing and hand washing in hypertensive patients. We analyzed 62,762 hypertensive patients over the age of 40 from the Community Health Survey 2020. The practice rate of hand washing was higher among women, younger age, higher education level, mask wearers when going out, and tooth brushing practitioners after lunch. The hand washing practice rate was higher in hypertensive patients who practiced tooth brushing. In conclusion, there was the relationship between oral hygiene and personal quarantine. It is necessary to prepare sustainable measures to increase the practice rate of infectious disease prevention behaviors for patients with underlying chronic diseases who are susceptible to COVID-19.

Pregnancy induces many physiologic changes, and it can cause hemoptysis in relation to the underlying or potential pulmonary diseases. Although hemoptysis is not a frequent event during pregnancy, a thorough search for its etiology and then immediate management should be initiated for a case of massive hemoptysis to avoid serious adverse effects on both the fetus and the mother. Most hemoptysis events during pregnancy are related to well known etiologies, but there are a few reported cases of hemoptysis in pregnant women who are without any underlying lung lesion. We report here on a case of a pregnant woman with total lung collapse due to hemoptysis, and a thorough search for the etiology after delivery could not reveal any etiology.

Ecthyma gangrenosum is usually seen in immunocompromised patients, particularly in those with underlying malignant disease. Ecthyma gangrenosum is rapidly progressing skin infection characterized by edema, hemorrhage, bullae and necrosis. We experienced the case of a 13-month-old male who had Ecthyma gangrenosum associated with liver abscess and renal abscess. The patient initially presented with skin lesions of multiple well defined central necrotic black colored large erythematous bullae. The multiple liver abscess with hepatomegaly and multifocal pyelonephritis with focal renal abscess revealed by abdominal ultrasonogram and computed tomogram. In the bacterial cultures of skin, urine and liver aspiration fluid, Pseudomonas aeruginosa was grown. The patient had no immune deficiency disease. We report this case with a review of related literatures.

Objectives : This study aimed to identify the group with high risk of suicide in general hospital inpatient by comparing the depression, anxiety, and distress and their clinical characteristics. Methods : The study included all patients admitted to a general hospital between January 2016 and December 2017, and the final 41,249 patients were analyzed. Distress thermometer (DT) and hospital anxiety-depression scale (HADS) were used for emotional state evaluation. Group with high risk of suicide was defined as showing more than 4 in the DT and more than 8 in one of the two subscales (anxiety and depression) of the HADS. Results : Among the subjects, 3,603 patients (8.7%) met the high-risk criteria for suicide. The group with high risk of suicide experienced more severe pain than the control patient group, and it was found that there was more underlying disease. Patients who reported pain showed higher scores than those who reported no pain on the DT and HADS subscales. Conclusions : Group with high risk of suicide showed more severe pain and more underlying disease. Therefore, suicide prevention program specifically targeted for the group with high risk of suicide should be developed according to the risk of the patient evaluated at the time of the admission.

The heifer electrocardiograph is a widely progressing research which is used in judgement to existence for a heart disease and analyzes electric potential changes of heart movement during continuous living of everyday after attaching to body portable holler recorder for twenty-four hours. In order to obtain electrocardiogram clearly, it must eliminate that 60Hz power line interference, baseline wandering, noise of muscle constriction. In holter electrocardiogram, the most big problem which is recorded signal of ECG(electrocardiogram) is a baseline wandering elimination, which is occurred by rhythm of respiration and muscle constriction of part from attaching to an electrode. Such baseline is roughly irregular wandering and shaking up and down therefore the part of baseline wandering elimination is very important because it is difficult of ECG diagnosis. In this study, it is stabilized baseline wandering in analog part as implementation f real-time signal processing digital filter so it is applicable to analyze patient's heart disease by way of design of baseline wandering elimination system.

The basal cell nevus syndrome is also known as the Gorlin-Goltz syndrom. It is a dominant autosomal disorder which is characterized by keratocystic odontogenic tumors in the jaw, skeletal abnormalities, and multiple basal cell nevi carcinomas. This study reports an 11-year-old boy with multiple odontogenic keratocysts in the jaw, hypertelorism, and frontal bossing. When a young patient has cystic lesions with an impacted permanent teeth, it is important to preserve the teeth. For a growing patient with impacted permanent teeth, a more conservative method is suggested, which will enable the preservation the permanent teeth in Gorlin-Goltz syndrome.

폐부종은 심인성, 혹은 비심인성 요인에 의해 발생한다. 심인성폐부종(Cardiogenic Pulmonary Edema, CPE)은 심질환, 좌심방 압력의 증가, 폐정맥과 폐모세혈관의 압력 증가와 관련있다. 이와는 대조적으로 비심인성 폐부종(Noncardiogenic Pulmonary Edema, NCPE)은 좌심방의 압력증가에 의해서 혹은 기저질환인 심장 질환과 관련없이 발생한 국소적인 정수압의 증가하여 발생하거나, 폐포나 모세혈관내 피표면의 투과도의 변화에 의해서 발생한다. 혹은 국소적인 정수압 및 투과도의 복합적인 변화 모두에 의하여 발생한다. NCPE의 환축을 적절하게 치료하기 위하여 CPE와 반드시 감별되어야 한다. 또한, 심인성 및 NCPE의 감별 및 적절한 처치를 위하여는 철저한 환축의 병력, 신체검사, 흉부방사선 촬영 등의 검사를 실시하여야 한다. NCPE는 원발요인과 치료반응에 따라 예후가 달라질 수 있다.

Nevoid basal cell carcinoma syndrome(NBCCS) is a autosomal dominant disorder, and its major manifestations are multiple basal cell carcinoma, keratocystic odontogenic tumor, rib anomalies, palmer and plantar pits, calcification of the falx cerebri. Keratocystic odontogenic tumor(KCOT) is defined as intraosseous tumor of odontogenic origin with a characteristic lining of parakeratinized stratified squamous epithelium and potential aggressive behavior. We report a case of a 3-year-old patient with nevoid basal cell carcinoma syndrome who initially presented with unilocular keratocystic odontogenic tumor in maxillary canine region. Keratocystic odontogenic tumor was treated by enucleation, and periodic follow-up check will be required for early diagnosis of additional diseases related with this syndrome.
