Persistent trigeminal artery is an embryonic remnant of the anastomotic channel linking the internal
carotid artery and the basilar artery. Cases of vertebrobasilar insufficiency caused by the persistent
trigeminal artery with internal carotid artery stenosis has been described previously, but vertebrobasilar
insufficiency entirely due to in situ stenosis of the persistent trigeminal artery has not been reported.
A 71-year-old man presented with frequent dizzy episodes. The brain MRI showed no parenchymal
lesions. MR angiography showed poor visualization of vertebrobasilar system. He was diagnosed as
having vertebrobasilar insufficiency. Cerebral angiography revealed that there was complete occlusion
at the vertebrobasilar junction, and the basilar artery was supplied by the persistent trigeminal artery
which had severe stenosis at its origin. There was no stenosis of the internal carotid artery of both
sides. We believe that this is the first report of vertebrobasilar insufficiency due to stenosed persistent
trigeminal artery, without internal carotid artery stenosis.
2.Challenges and Pitfalls of Stroke Therapeutics Research.
Korean Journal of Stroke 2011;13(1):11-15
Ischemia-reperfusion injury is complicated with multiple injury pathways. If a particular agent is used to restore blood flow and prevent cell death, many damaged neurons may come back to life. However, for stroke victims, there are no effective curative therapeutic approaches available other than thrombolytic treatment. The efficacy of neuroprotective agents are limited by low diffusion, narrow time window, strict dose titration, and lack of confidence at the preclinical level. NXY-059 reflects the fundamental limitation of neuroprotectant. There are recent attempts to overcome these limitations, with use of annexin A2, fingolimod, hydrogen, nitrite, and more. By covering two components, this report reviews what we have recently learned. In addition, it sheds light on some of the newer issues in clinical application.

Fetal teratomas rarely complicate pregnancy,having an incidance of only 20,000:1 to 40,000:1 of live births. Overthere, cervical teratomas are rare and accounts for only 5.5% of all neonatal teratomas. We have experienced a large cervical immature teratoma and present this case with a brief review of literatures.

4.New Pathophysiological Considerations on Cerebral Aneurysms.
Neurointervention 2018;13(2):73-83
Cerebral aneurysm is a common cerebrovascular disease that is sometimes complicated by rupture or an enlarged mass. We are now aggressively evaluating and managing unruptured cerebral aneurysms based on a significant concern for the high morbidity and mortality related to its associated complications. However, the actual rupture rate is very low and the diagnostic and treatment modalities are expensive and invasive, which may lead to unnecessary costs and potential medical complications. This disproportionate situation is related to a poor understanding of the natural course and pathophysiology of cerebral aneurysms. In consideration of the concept that not all cerebral aneurysms must be removed, we need to examine their course and progression more accurately. Cerebral aneurysms may follow a variety of pathophysiological scenarios over their lifetime, from formation to growth and rupture. The disease course and the final outcome can differ depending on the timing and intensity of the pathological signals acting on the cerebral vessel wall. We should delineate a method of predicting the stability and risk of rupture of the lesion based on a comprehensive knowledge of the vessel wall integrity. This review deals with the basic knowledge and advanced concepts underlying the pathophysiology of cerebral aneurysms.

BACKGROUND: Overweight and obesity are associated with increased mortality and morbidity. Obesity is influenced by multiple factors, both genetic and environmental factors. We investigated the relationship between socioeconomic, behavioral, dietary, reproductive factors and body mass index(BMI). METHODS: The subject were 3000 adults who had visited the Health Screening and Diagnosis Center of Yeungnam University School of Medicine from February to June, 1997. We evaluated BMI and occupation, exercise, smoking, alcohol intake, total calory intake, fat and carbohydrate intake in both gender and reproductive factors in women. Then, we analyzed the association between BMI and such variables as above. RESULTS: 1629 men and 1371 women were analyzed. The mean BMI was 23.4+/- 2.8kg/M(2) in men, 22.9+/- 3.1kg/M(2) in women. In both gender, 9.7% of our population had BMl over 27. Mean BMI increased with age. Those who were active and light smokers( 20cigarette/day) had the lowest BMI in men. But no relationship was observed between BMI and exercise, smoking in women. Heavy alcohol drinkers(> 1cup/day) had higher BMI than other group in both gender. We found significant correlation between BMI and total calory intake, calory intake to recommended calory ratio in both gender. In women, the group whose number of parity was above 3 had significantly higher BMI than the other. And age at first birth was significantly correlated with BMI in a negative direction. CONCLUSIONS: Our results showed that BMI was associated with age, smoking, alcohol, total calory intake, calory intake to recommended calory ratio, parity, age at first birth. Socioeconomic class, exercise and diet composition appeared to have little influence.

BACKGROUND: Bronchial asthma is a complex genetic disorder. Although serum IgE level and bronchial hyperresponsiveness are well known to be under genetic control, the influence of genetic factors on basophil releasability has been seldom studied. OBJECTIVE: The present study was carried out to investigate whether genetic factors may influence the basophil histamine releasability. MATERIALS AND METHODS: We studied 50 children, 32 with atopic asthma (AA) and 18 normal control (NC), and their parents. Suspensions of leukocytes were isolated and stimulated with Ca ionophore and anti-IgE antibody. Then, histamine in the supernatant was as-sayed by an automated fluorometric analyzer. RESULTS: Among the probands, AA children had a significantly higher anti-IgE induced histamine release than NC children. In contrast, Ca ionophore-induced histamine release was similar between the two groups. Ca ionophore-induced or anti-IgE-induced histamine release was not significantly different between parents of AA children and those of NC children. However, the maximal histamine release by Ca ionophore in parents had a significant correlation with that of probands, whereas the values by anti-IgE were not correlated between probands and their parents. CONCLUSION: We confirmed that basophils from patients with atopic asthma are characterized by a specific increase in IgE-mediated histamine release. The significant correlation of Ca ionophore-induced maximal histamine release between children and their parents suggests that genetic factors may play an important role in the control of non-IgE-mediated relessability from basophils.

BACKGROUND: There have been no studies of airway management strategies for difficult intubation and cannot intubate, cannot ventilate (CICV) situations in Korea. This study was intended to survey devices or methods that Korean anesthesiologists and intensivists prefer in difficult intubation and CICV situations. METHODS: A face-to-face questionnaire that consisted of a doctor's preference, experience and comfort level for alternative airway management devices was presented to anesthesiologists and intensivists at study meetings and conferences from October 2014 to December 2014. RESULTS: We received 218 completed questionnaires. In regards to difficult intubation, the order of preferred alternative airway devices was a videolaryngoscope (51.8%), an optical stylet (22.9%), an intubating laryngeal mask airway (11.5%), and a fiber-optic bronchoscope (10.6%). One hundred forty-two (65.1%) respondents had encountered CICV situations, and most of the cases were identified during elective surgery. In CICV situations, the order of preferred methods of infraglottic airway management was cricothyroidotomy (CT) by intravenous (IV) catheter (57.3%), tracheostomy by a surgeon (18.8%), wire-guided CT (18.8%), CT using a bougie (2.8%), and open surgery CT using a scalpel (2.3%). Ninety-eight (45%) of the 218 respondents were familiar with the American Society of Anesthesiologists' difficult airway algorithm or Difficult Airway Society algorithm, and only 43 (19.7%) had participated in airway workshops within the past five years. CONCLUSION: The videolaryngoscope was the most preferred device for difficult airways. In CICV situations, the method of CT via an IV catheter was the most frequently used, followed by wire-guided CT method and tracheostomy by the attending surgeon.

To investigate the risk factors and clinical characteristics of postrenal transplant diabetes mellitus (PTDM), we reviewed the records of 177 renal allograft recipients in Maryknoll Hospiatal whose allografts had functioned longer than 6 months. Nineteen patients (10.7%) developed PTDM at 5.0+/-7.8 (1-52) months; 9 (47%) of these within 1 month. PTDM patients were older than nondiabetic renal transplants (42+/-2 vs 37+/-1 years, P<0.05). Body mass index tended to be higher in PTDM (23.5+/-1.0 vs 21.8+/-0.3kg/m2, P=0.09). Number of acute rejections (0.6+/-0.2 vs 0.5+/-0.1) and serum creatinine at 1 year after transplantation (1.2+/-0.8 vs 1.3+/-0.3mg/dL) were not different. Fasting (103.6+/-10.4 vs 84.4+/-1.6mg/dL, P<0.05) and postprandial (189.2+/-24.8 vs 118.6+/-2.3 mg/dL, P<0.01) blood sugars, measured before transplantation, were higher in PTDM. CsA blood level at 1 month posttransplantation was higher in PTDM (350+/-34 vs 279+/-8ng/mL, P<0.05). Fasting serum insulin was significantly higher (28.2+/-12.2 vs 7.3+/-2.0 microunit/dL, P<0.05) and serum C-peptide tended to be higher in PTDM patients compared with euglycemic renal recipients (6.3+/-1.6 vs 3.8+/-0.9ng/dL, P=0.08). All the PTDM patients were treated by either insulin or oral agent; 15 of 19 required no treatment after 4.7+/-6.9 months. In conclusion, prevalence of PTDM was 10.7%. PTDM patients were older. Body mass index was tended to be higher. Fasting and postprandial blood sugars, measured before transplantation, were higher in PTDM. Faslting serum insulin was higher and C-peptide tended to be higher in diabetics. These results suggested that increased insulin resistance plays a major role in the pathogenesis of PTDM.

BACKGROUND: The rate of suicide of adolescents is recently significantly increasing in South Korea. Suicide is the first leading cause of death of adolescents aged 15 to 19 years in South Korea and the mortality rate due to suicide of adolescents is 8.9 per 100,000. The aims of this study is to investigate factors that affect suicidal ideation through inventory and scale. METHODS: A questionnaire was conducted to 820 high school students in a city, and 776 subjects who finished questionare were included in this study. Suicidal ideation, school bullying, excessive sexual thought and family conflict were checked by adolescent mental health and problem behavior screening questionnaire-II (AMPQ-II). Internet addiction degrees and depression was evaluated by internet addiction scale (IAS) and Beck's depression inventory (BDI), respectively. RESULTS: AMPQ-II, IAS, BDI, school bullying, suicidal ideation, and family conflict were closely related to each other. Binary logistic analysis showed that victims of school bullying (odds ratio [OR], 2.3; 95% confidence Interval [CI], 1.439-3.816), AMPQ-II high risk (OR 4.9; CI 2.546-9.433) and depression of all grade (OR 1.8 [mild], 2.2 [moderate], 6.4 [severe]) were related to suicidal ideation. CONCLUSIONS: Presence of school bullying, depression, and AMPQ-II high risk were closely related to suicidal ideation of high school students. Thus, AMPQ-II and BDI score can use as a screening tool for adolescent suicide ideation.

PURPOSE: The remarkable progress in information and communication technology has had a great effect on the healthcare delivery system. The development of smart phone applications is a new field. The aim of our research was to provide assistance in developing smart phone applications for community health nursing. METHODS: Based on an informative approach, this study developed persona and site maps, followed by a storyboard as a way of analyzing users' requirements and designing responses in the context of smart phone application development methodology. RESULTS: We developed persona, user interface and database design successfully, and then seven nurses selected four nursing problems (income, residence, pain, and digestion hydration). The search time in seconds for the 2005 English OMAHA guidelines to find three nursing interventions for these problems was used to evaluate the effectiveness of the smart phone application. The results showed that smart phone applications' search was 21 times faster on the average than book guidelines. CONCLUSION: An English version of the OMAHA system application was developed for the Android smart phone market. It is hoped that smart phone applications such as this will be used internationally for nursing education.
