This is a case report of a cystic hygroma with polycystic kidney in a fetus which was suspected by ultrasonography and was confirmed by autopsy. Recently, we have experienced this case in 25-year old woman repeatedly and we report that with a brief review of relevant literature.

PURPOSE: We performed dynamic MR imaging using GdDTPA to find characteristic enhancement pattern of hepatic hemangioma distinguishing from hepatocellular carcinoma. METHODS AND MATERIALS: 28 hepatic hemangiomas and 10 hepatocellular carcinomas were evaluated. Serial dynamic scans after Gd-DTPA(0.1mmol/kg) intravenous injection were obtained by using 0.5T machine and analyzed contrast-to-noise ratio(CNR) of the lesion and enhancement pattern on each scan. RESULTS: Hepatic hemangiomas had positive CNR from 1-2 minute images, and revealed typical "fill-in phenomenon" on early phase with prolonged enhancement in 26 cases(92.8%), and early homogeneous enhancement with isointensity on delayed phase in 2 cases(7.2%) of small hemangiome~ Hepatocellular carcinomas revealed inhomogeneous enhancement with hypointensity on delayed phase in 10 cases(100%) and 3 cases (30%) of capsular enhancement. CONCLUSION: Hepatic hemangioma can be easily distinguished from hepatocellular carcinoma by using Gd DTPA enhanced dynamic MR imaging according to its typical enhancement pattern of "fill-in phenomenon" and prolonged enhancement.

We studied 21 neonates who required mechanical ventilation during study period in NICU OF Il Sin Christian Hospital with diagosis of prematurity, IRDS, pneumothorax and diaphragmatic hernia to evaluate the accuracy of pulse oximeter in predicting the arterial oxygen saturtion, hypoxia and hyperoxemia. We also studied whether the changes of birth weight, hematocrit, blood pressure and body temperature affect the accuracy of pulse oximeter. The results are 1) Linear regression analysis revealed a close correlation between in vivo pulse oximeter readings and in vitro SaO2 measurements in patients (Y=0.008X+12.34, r=0.946) 2) The changes of birth weight, hematocrit, blood pressure and body temperature did not affect the accuracy of pulse oximeter. 3) SpO2-PaO2 relationship was similar to the SsO2-PaO2 relationship. 4) When Nellcor N-100 pulse oximeter was setted at alarm limit 96% to avoid hyperoxemia, it identified 16 of 22 hyperoxemic instances (sensitivity 73%) and alarmed falsely in 48 of 92 nonhyperoxemic instances (specificity 59%).

Purpose: This study aimed at understanding the experiences of mental health nurses caring for mentally ill patients. Methods: Van Manen’s hermeneutic phenomenological method was used to analyze qualitative data. The partici- pants were 8 mental health nurses who worked in hospitals, mental health welfare centers, or psychiatric reha- bilitation facilities. Data were collected through in-depth interviews from July 24, 2017, to June 20, 2018. Results: Eight essential themes emerged: “A body that must endure severe symptoms”, “A hand that cares for the wound”, “Ambivalence in a closed space”, “Making them adapt to the open world”, “Being together and getting close to the patients”, “Going forward, leaning on each other”, “Time to protect even a small light”, and “Becoming a shining star by myself”. Conclusion Strategies are needed to cope with patient violence and prevent psychological trauma. Mental health nurses should be trained for empathetic competency to understand symptoms and build trusting relationships. Caring requires respect and love based on humanity. Mental health nurses learn from patients and experience mutual care that grows through self-reflection. Policy support including financial and manpower security is essential to improving the quality of care and preventing exhaustion.

In 10 cases with intracranial arterivenous malformation (AVMs) diagnosed by MR spin echo images, MR angiography was evaluated and compared with conventional angiography in regard to depiction of nidus, arterial feeders, and draining veins. Spin echo images demonstrated the nidus of the AVM in all cases, but displayed the feeding vassels inadequately. These vessels were directly visualized with 3 dimensional STAGE(small tip angle gradient echo) MR angiography using rephasing/dephasing pulse sequences. In 5 cases MR angiography and conventional angiography showed the same results. However, in the others, MR angiography showed lower resolution than conventional angiography. MR angiography is useful in preangiographic evaluation of intracranial AVM but improvement in image resolution, which is dependent on MR hard ware and pulse sequence, is still to be desired.
