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.

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.

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: 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: 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: Reduced cerebral blood flow and microvascular abnormalities have been suggested as the vascular pathogenesis of Alzheimer's disease (AD). Transcranial Doppler sonography (TCD) can be used as a noninvasive method for measuring cerebral vasomotor reactivity (VMR) which represent the capability of arterioles to dilate and constrict in order to maintain cerebral blood flow. OBJECTIVE: The objective of this study was to determine whether VMR is decreased in AD patients. Methods: Seventeen consecutive patients who met NINDS-ADRDA criteria for AD, and 17 age- and sex-matched controls were included in this study. MRI and MRA were performed for the grading of white-matter lesions. Patients with cerebral infarct or stenosis of the middle cerebral artery (MCA) were excluded. The fixed TCD probe was used to monitor the mean flow velocity (MFV) in the MCA. A 6-L rebreathing bag was applied to patients for at least 5 minutes to elevate the CO2 concentration, which was continuously monitored with a capnometer. VMR was calculated as the percentage change in the MFV. RESULTS: Baseline characteristics - including cerebrovascular risk factors, grades of white-matter lesions, baseline MFV, and pulsatility index - did not differ between the two groups. Mini-Mental State Examination score was significantly low in AD group (20.5 vs. 27.5, p<0.05). VMR was significantly reduced in AD group both in the right-side (24.5% vs. 36.6%, p<0.05) and left-side (20.7% vs. 34.1%, p<0.05) MCAs. CONCLUSIONS: Our finding that VMR is reduced in AD may be suggestive of underlying microangiopathic mechanism in AD patients. Future studies should check the validity of these experimental and hypothesis-generating pilot results.

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.

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.
