Purpose: This study was conducted to evaluate the record completeness of the nursing process in the Electronic Nursing Record(ENR) in a university hospital. Methods: We compared nursing statements documented in 2004 with those from the year 2007, given the fact that the ENR system had been utilized since 2004. The ENRs of 35 gastrectomy patients in each year were selected for evaluation. The selected data were 11,822 nursing statements in 2004 and 27,870 in 2007. Results: The number of nursing records which documented the whole nursing process completely was 4,010 (48.3%) in 2007, whereas 513 (5.9%) in 2004 (p<.001). The number of incomplete records in 2004 was 8,142 (94.1%), while 4,300 (51.7%) in 2007 (p<.001). The number of nursing diagnoses was 846 in 2004 and 4,313 in 2007, which increased in number more than 5 times. The most frequently used diagnoses were 'pain', 'risk for infection' and 'risk for ileus' in both years. Conclusion: There was a significant increase in the record completeness on nursing process in 2007 compared to the records in 2004. The reasons for this increase are attributed to nurse training for encouraging to complete recording and nursing record auditing.

Purpose: The purpose of this study was to investigate hemato-oncology patients' discomfort and bleeding in relation to the bedrest time after bone marrow examination. Methods: A descriptive correlational study was conducted. The data were collected using self- report questionnaire from total of 131 patients who underwent bone marrow examination from January 2017 to September 2017. Data were analyzed with descriptive statistics, Wilcoxon Signed-rank test, McNemar's test and logistic regression. Results: The level of discomfort after 4 hours of bedrest was significantly higher when compared to 2 hours of bedrest(p<.001). The occurrence of bleeding after 2 hours of bedrest was significantly higher than 4 hours of bedrest(p<.001), however the degree of bleeding was slight. No bleeding occurred in 84% of the patients after 2 hours of bedrest. Conclusion: The results of this study demonstrated that shortening the bed rest time after bone marrow examination was helpful in improving the patient's well-being. Bedrest time could be shortened according to the site of bone marrow examination and patient's condition.

Purpose: This study was performed to verify reliability and validity of the Korean Pediatric Patient Classification System (KPPCS) and estimate nursing time conversion index. Methods: The study was conducted in 9 children's hospital which included various areas and size of bed settings. To verify intraclass correlation reliability and construct validity, staff nurses and nurse managers of 21 wards classified 575 patients according to KPPCS comparing differences by age, days of stay, type of stay and medical department. Direct and indirect nursing time of 575 patients were measured by 284 nursing staffs by stopwatch observation and self reports for 24 hours. Results: KPPCS has 12 categories, 55 nursing activities and 80 criterions. High agreement among nurses (r=.91, p<.001) suggested substantial reliability. Construct validity was verified by comparing differences in age, days of stay, type of stay and medical department (p<.05). The correlation of nursing time and classification score was also statistically significant (r=.59, p<.001). The nursing time conversion index was 10.78 minutes per 1 classification score. The entire patient group were classified to four groups using KPPCS. Conclusion: The findings suggest that KPPCS would be a useful tool for estimating nursing demands related to the complexity of pediatric patients.

니볼루맙을 사용하는 도중 폐렴이 발생할 수 있고, 폐렴이 의심되면 치료하기 이전에 바이러스를 포함한 감염 여부와 림프관성 암의 진행 상태 및 울혈성 심장 기능 상실 여부 등의 감별이 필요하며 폐렴의 등급과 중증도를 평가하여 스테로이드를 경험적으로 쓰는 것이 중요하다. 본 증례에서는 감염을 배제하기 위하여 기관지 폐포세척을 시행한 후 폐포자충 폐렴이 진단된 사례로 드물기는 하지만 페포자충 폐렴의 감별이 필요함을 보여주어 증례로 보고하는 바이다.

동결절편검사는 수술과 연계하여 암 전이 여부를 판단하기 위한 응급한 병리검사가 필요할 때 이용된다. 합성곱 신경망은 이미지 분류에 뛰어난 성능을 보이는 딥러닝 기법으로 본 논문에서는 이를 이용하여 유방암 전이 여부를 자동적으로 진단하는 방법을 제안한다. 실험과정은 전처리, 학습, 후처리의 과정으로 구성되어 있으며, 합성곱 신경망으로는 Resnet-18 모델을 사용하였다. 실험결과 예측 정확도 및 종양의 최대 길이 정합 여부를 점수로 환산하여 약 0.514 의 결과를 보였다.

Immune checkpoint inhibitor is associated with variety of immune-related adverse events. We present a case of polyneuropathy induced by immune checkpoint inhibitor, which was refractory to steroid and immunoglobulin. While high-dose steroid and immunoglobulin were not effective, we tried rituximab which is effective in other immune-mediated polyneuropathy. After rituximab treatment, patient's clinical symptom and nerve conduction study finding was markedly improved. We suggest rituximab might be effective in polyneuropathy induced by immune checkpoint inhibitor.

Background/Aims: To investigate the predictive factors for improvement of atrophic gastritis (AG) and intestinal metaplasia (IM). Materials and Methods: A total of 778 subjects were prospectively enrolled and followed up for 10 years. Histological analysis of AG and IM was performed by using the updated Sydney system. To find the predictive factors for reversibility of AG and IM, 24 factors including genetic polymorphisms and bacterial and environmental factors were analyzed. Results: In all subjects, the predictive factor by multivariate analysis for improvement of both antral and corpus AG was successful eradication. The predictive factors for improvement of antral IM were age and successful eradication. The predictive factor for improvement of corpus IM was successful eradication. In patients with Helicobacter pylori infection, age and cagA were predictive factors for improvement of AG and IM. In patients with H. pylori eradication, monthly income and cagA were predictive factors for improvement of AG and IM. Conclusions: H. pylori eradication is an important predictive factor of regression of AG and IM and would be beneficial for the prevention of intestinal-type gastric cancer. Young age, high income, and cagA are additional predictive factors for improving AG and IM status. Thus, various factors affect the improvement of AG and IM.

Background/Objectives: Cancers of the abdominal or pelvic organ rarely metastasize to the cervical lymph nodes. Although it indicates distant metastasis, perceivable prolongation of survival or cure may be possible in selected cases. We sought to identify patients with cervical metastasis from cancers below the diaphragm and identify patients who may benefit from aggressive treatment. Materials & Methods: From 2009 to 2017, patients with pathologically confirmed metastatic cervical lymph nodes originating from below the diaphragm were included for analysis. Patient demographics, cancer characteristics, treatment course, and clinical outcomes were analyzed. Results: 208 patients were identified. Left supraclavicular node (Virchow's node) was the most frequently involved. Irrespective of treatment, survival for uterine cervical and ovarian cancers was significantly longer than that of other primaries. Patients with isolated cervical metastasis (oligometastasis) had significantly longer median survival compared to patients with concomitant bone, lung, brain, and mediastinal metastases. Conclusion: Although cervical metastasis from cancers of the abdominal and pelvic organ represent distant metastasis, patients with uterine cervix and ovary primary and oligometastatic lesions may benefit from aggressive treatment. Prudent patient selection and further investigation is warranted.

목적 만성 뇌동맥 협착-폐색증에서 아세타졸아미드 부하 다상 동맥 스핀 표지(multi-phase arterial spin labeling; 이하 MP-ASL) 자기공명관류영상을 이용하여 뇌혈류 예비능(cerebrovascular reservoir; 이하 CVR)과 동맥 통과 시간(arterial transit time; 이하 ATT)의 변화를 탐색하였다. 대상과 방법 2019년 6월부터 2020년 10월까지 새롭게 만성 협착-폐색증으로 진단되어 아세타졸아미드 부하 MP-ASL을 시행한 환자를 후향적으로 모집하였다. 부하 전후의 뇌혈류(cerebral blood flow), CVR, 부하전 ATT 및 부하 전후의 ATT 변화량을 중증 협착과 완전 폐색간, 만성 뇌경색 병변의 유무에 따라 비교하였다. 결과 5명의 양측성 협착-폐색을 포함하여 총 32명의 환자가 본 연구에 포함되었다. CVR은 완전 폐색에서 중증 협착보다 유의하게 낮았다(26.2% ± 28.8% vs. 41.4% ± 34.1%, p = 0.004). ATT의 변화는 두 군간 유의한 차이는 없었다(p = 0.717). 만성 뇌경색 병변의 유무에 따른 CVR의 통계적 차이는 미미하였다(29.6% ± 39.1% vs. 38.9% ± 28.7%, p = 0.076). 하지만, 만성 뇌경색 병변이 있는 환자에서 ATT의 단축 정도는 유의하게 작았다(-54 ± 135 vs. -117 ± 128 ms, p = 0.013). 결론 만성 협착-폐색증에서 아세타졸아미드 부하 MP-ASL 검사는 MRI 기반의 CVR 평가 도구로 사용될 수 있다.
