PURPOSE: In addition to regulating calcium and phosphorus homeostasis and bone metabolism, vitamin D is known as an immune modulator. Recently, there has been increased worldwide interest in the association between low levels of vitamin D and allergic diseases. The purpose of this study was to assess the relationship between serum vitamin D levels and allergic/vasomotor rhinitis (AR/VR) in children. METHODS: This study included 164 patients. The sample included 59 patients with AR, 42 patients with VR, and 63 controls. Their ages ranged from 0 to 16 years. We examined the levels of 25-hydroxyvitamin D, Immunoglobulin E, specific IgE, and eosinophil cationic protein; peripheral blood eosinophil count; and the results of a skin prick test. RESULTS: Serum 25-hydroxyvitamin D levels were 19.0+/-8.5 ng/mL in the AR group, 25.5+/-10.9 ng/mL in the VR group, and 26.9+/-10.7 ng/mL in the control group. After adjustment for body mass index and season at the time of blood sampling, vitamin D levels in the AR group were lower than those of the VR group (P=0.003) and control group (P<0.001). Vitamin D levels were inversely correlated with Immunoglobulin E levels (r=-0.317, P<0.001). AR patients with food allergy or atopic dermatitis did not have lower levels of 25-hydroxyvitamin D than AR patients without these diseases. CONCLUSION: This study demonstrates a possible relationship between vitamin D levels and allergic rhinitis in Korean children.

PURPOSE: Bilateral high signal intensity in basal ganglia on Tl-weighted images is unusual. the purpose of this study is to describe the pattern of high signal intensity and underlying disease. METHODS AND MATERIALS: During the last three years, 8 patients showed bilateral high signal intensity in basal ganglia on Tl-weighted image, as compared with cerebral white matter. Authors analized the images and underlying causes retrospectively. Of 8 patients, 5 were male and 3 were female. The age ranged from 15 days to 79 years. All patient were examined by a 0.5T superconductive MRI. Images were obtained by spin echo multislice technique. RESULTS: Underlying causes were 4 cases of hepatopathy, 2 cases of calcium metabolism disorder, and one case each of neurofibromatosis and hypoxic brain injury. These process were bilateral in all cases and usually symmetric. In all cases the hyperintense areas were generally homogenous without mass effect or edema, although somewhat nodular appearence was seen in neurofibromatosis. Lesions were located in the globus pallidus and internal capsule in hepatopathy and neurofibromatosis, head of the caudate nucleus in disorder of calcum metabolism, and the globus pallidus in hypoxic brain injury. CONCLUSION: Although this study is limited by its patient population, bilateral hyperintense basal ganglia is associated with various disease entities. On analysis of hyperintense basal ganglia lesion, the knowledge of clinical information improved diagnostic accuracy.

Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology. We report a case of KD with acute respiratory distress syndrome (ARDS) after intravenous immunoglobulin (IVIG) infusion. Lung manifestations associated with KD have previously been reported in the literature. Although IVIG infusion is an effective therapy for acute KD, there are some reported complications related to IVIG infusion: hypotension, aseptic meningitis, acute renal failure, hemolytic anemia, etc. The case of KD reported here was treated with IVIG and aspirin. A few days after recovery from KD, the patient developed fever and maculopapular rash. A diagnosis of relapse KD was made and retreated with IVIG infusion. However, the patient developed ARDS four days after the second IVIG infusion. The patient recovered from ARDS after nine days of ICU care, which included high frequency oscillation ventilation with inhaled nitric oxide, steroid treatment and other supportive care.

BACKGROUND: Various tools for the acute response system (ARS) predict and prevent acute deterioration in pediatric patients. However, detailed criteria have not been clarified. Thus we evaluated the effectiveness of bradycardia as a single parameter in pediatric ARS. METHODS: This retrospective study included patients who had visited a tertiary care children's hospital from January 2012 to June 2013, in whom ARS was activated because of bradycardia. Patient's medical records were reviewed for clinical characteristics, cardiologic evaluations, and reversible causes that affect heart rate. RESULTS: Of 271 cases, 261 (96%) had ARS activation by bradycardia alone with favorable outcomes. Evaluations and interventions were performed in 165 (64.5%) and 13 cases (6.6%) respectively. All patients in whom ARS was activated owing to bradycardia and another criteria underwent evaluation, unlike those with bradycardia alone (100.0% vs. 63.2%, p = 0.016). Electrocardiograms were evaluated in 233 (86%) cases: arrhythmias were due to borderline QT prolongation and atrioventricular block (1st and 2nd-degree) in 25 cases (9.2%). Bradycardia-related causes were reversible in 202 patients (74.5%). Specific causes were different in departments at admission. Patients admitted to the hemato-oncology department required ARS activation during the night (69.3%, p = 0.03), those to the endocrinology department required ARS activation because of medication (72.4%, p < 0.001), and those to the gastroenterology department had low body mass indexes (32%, p = 0.01). CONCLUSIONS: Using bradycardia alone in pediatric ARS is not useful, because of its low specificity and poor predictive ability for deterioration. However, bradycardia can be applied to ARS concurrently with other parameters.

Analysis of our primary bronchogenic carcinoma is restricted to 65 cases that have been regarded as having satisfactory histological and cytological proof of diagnosis by bronchial washing and bronchos opic biopsy and they were primarily diagnosed by roentgenography. Of these 65 cases, 59 cases were diagnosed by bronchoscopic biopsy and 6 cases were proved by bronchial washing. In the sex incidence, there were 49 males and 16 females, The peak incidence of bronchogenic carcinoma was 41.5 per cent in the fifth decade, 30.8 per cent in the fourth decade, and 1.5 per cent in the second decade. Cough, sputum raising, chest pain, and dyspnea were the most common complaints but three patiens had no signs or symptoms. The pathological classification, metastasis and complication were discussed for these 59 cases. Radiological classification of lung cancer revealed the following types: central pneumonic form; central solid form; central infiltrating form; peripheral solid form; peripheral cavitary form. 86.2% was central hilar type and 13.8% was peripheral type. For distribution of these 65 cases, 60% showed right lung involvement and 40% showed left lung involvement.

The effects of dehydration on vasopressin and oxytocin immunoreactive neurons in the hypothalamus was investigated by using a immunohistochemistry. Adult Mongolian gerbil[Meriones unguiculates] were deprived of drinking water. Dehydrated animals were sacrificed on the 7th, 14th and 21st day of water retriction. The results are as follows : 1. The body weights were decreased about 1.8% daily. On the 21st day of dehydration, they were shown up to 45% compare to the control. 2. In the hypothalamus of the control group, majority of vasopressin and oxytocin immunoreactive neurons were located in the supraoptic and paraventricular nuclei. 3. Changes due to dehydrated stimulation were mainly observed in vasopressin immunoreactive neurons. And these changes in supraoptic nuclei were more severe than those in paraventricular nucleus. Size of vasopressin immunoreactived cells and of areas were increased as to proceed the dehydration. The numbers of those were increased on the 7th day of dehydration, and then they were continously decreased. 4. Although oxytocin immunoreactive neurons were slightly changed in numbers during dehydration, they were not shown conspicuous changes compare to vasopressin immunoreactive neurons. Thus it is appeared that vasopressin secretory neurons in the hypothalamus of Mongolian gerbil are affected by osmotic stress induced dehydration while oxytocin neurons may be affected by other factors.

The effects and interactions of pipecuronium and atracurium with diltiazem and verapalmil on the electrically-evoked twitch response, train-of-four and tetanic stimulation were studied in the isolated rat phrenic-hemidiaphragm preparation. Pipecuronium (3X10(-7) -4X10(-6)) and atracurium (10(-6) -3X10(-5) M) decreased the electrically-evoked twitch response, train-of-four and tetanus ratio in a dose-related fashion and the pipecuronium was more potent than atracurium. The inhibitory effects of pipecuronium and atracurium were potentiated by pretreatment of 5 uM diltiazem and verapamil, Ca++-channel blokers, in which the concentration of diltiazem or verapamil has no obvious effect on the twitch response itself. Futhermore, it is noteworthy that the inhibitory effects of pipecuronium and atraeurium were markedly potentiated by 150 uM hemicholinium pretreatment. On the basis of these findings, the results of present study suggests that the muscle relaxation by pipecuronium and atracurium is mediated by pre- and post-junctional receptor blockade, and that diltiazem or verapamil intensifies neuromuscular blockade produced by these musele relaxants. The potentiating effect of diltiazem or verapamil may be due to blocking influx of calcium and/or release of acetylcholine from presynaptic nerve terminals.

PURPOSE: To give a help in the interpretation of cardiac cine-MR examination, the extent, shape, and timing of appearance of signal void regions near atrioventricular(A-V) valve prospectively evaluated in the healthy population. MATERIALS AND METHODS: Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricualr valve areas. RESULTS: Transient signal void was observed within the atrium near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called "physiologic atrioventricular valvular insufficiency". Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects didnot show any evidences of physiologic insufficiency. This physiologic condition does not extend more than lcm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. CONCLUSION: Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpfal in the study of the normal cardiac physiology.

BACKGROUNDS: Intestinal obstruction is one of the main causes of neonatal operations. It is caused by congenital factors, inherited diseases, and acquired diseases. A study was made to understand the status of neonatal intestinal obstruction cases at our hospital. METHODS: This was a clinical analysis of 53 cases of neonatal intestinal obstruction which had been experienced from March 1992 to February 1998 at the Department of General surgery, Sung-Ae General Hospital. RESULTS: 1) Operations for neonatal intestinal obstructions accounted for 42.4% of all neonatal operations. 2) There were 38 males and 15 females; the male-to-female ratio was 2.5:1. 3) Gestational period of 9 cases (16.9%) was less than 36 weeks and the weight in 10 cases (18.8%) wre below 2,500 gm at birth. 4) The main clinical symptoms on admission were vomiting or abdominal distension. 5) There were 49 cases (92.4%) of mechanical obstruction and 4 cases of a paralytic ileus. 6) Associated anomalies were present in 9 cases (16.9%). 7) The postoperative complication and motality rates were 30.1% and 7.5% respectively. CONCLUSIONS: Our clinical data might provide clinical suspicisions leading to early diagnosis and treatment.
