Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication and restricted, repetitive patterns of behavior and interest. Sleep problems are not uncommon in children with autism spectrum disorders. Symptoms of insomnia are the most frequent sleep problems in individuals with ASD. Sleep problems can cause significant difficulties in the daily life of children with ASD and their families. Genetic factor, deregulations of melatonin synthesis, extraneous environmental stimuli and psychiatric and medical conditions may cause sleep problems. The first line treatment of sleep problems in ASD includes managements for potential contributing factors and parent education about sleep hygiene care for child and behavioral therapy. Supplementation with melatonin may be effective before considering other medications, such as risperidone, clonidine, and mirtazapine.

BACKGROUND: Echocardiographically detected left ventricular(LV) hypertrophy is a risk factor for cardiovascular morbidity and mortality. A better understanding of the determinants of LV mass may aid in strategies directed toward the promary and secondary prevention of LV hypertrophy and its consequences. Previous studies have reported that male gender, arterial blood pressure(BP), obesity, age, aortic valvular stenosis, dietary sodium, endocrine factors, and physical activity are positively correlated with LV mass. Of these determinants male gender, hypertension, and obesity are well known but age and blood pressure in healthy adults are controversial. To assess the determinants of LV mass, the relation of 2-dimensional(2D) echocardiographically determined LV mass to body mass inedx(BMI), age, sex, casual BP, and 24 hour ambulatory blood pressure(ABP : systolic, diastolic, and mean BP of 24 hour, day-time, and night-time) was examined in healthy adults. METHODS: The study population consisted of 200 healthy adults who were normotensive, nonobese, and had no evidence of cardiovascular disease(range in age from 20 to 69 years, five decades, 20 men and 20 women per each decade). LV mass was derived from area length method measurements obtained by 2D echocardiography and corrected for height. ABP monitoring was performend over 24 hour(divided into day-time(6am-10pm) and night-time(10pm-6am)periods) with 30 minute inervals. RESULTS: 1) BMI was significantly and independently related to LV mass corrected for height (p<0.001, partial R2=0.31 in men and 0.43 in women). An increase of BMI by 1 kg/m2increased LV mass corrected for height by 1.9g/m in men and 2.0g/m in women. 2) Age was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.15 in men and 0.17 in women). The increments of Lv mass corrected for height per decade were 2.1 g/m in men and 3.4 g/m in women. 3) Gender was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.12), which was greater in men than in women by 6.34g/m. 4) Casual Bp and 24 hour ABP were not significantly associated with LV mass corrected for height in total population and women, and 24 hour systolic BP was significantly related to LV mass corrected for height only in men(p<0.001) with weak partial R2(0.05). CONCLUSION: BMI, age, and male gender were statistically significant and independent correlates of LV mass corrected for height(p<0.001). Maintenance of ideal body weight and normal BP, weight reduction in obese persons and BP control inhypertensive patients may contribute to the primary and secondary prevention of LV hypertrophy and its sequalae.

Severely worn dentition causes various complications such as loss of tooth structure, discoloration, pulp complications and loss of function and aesthetics. In this case, the patient showed particularly severe attrition in the anterior teeth and lack of space for restoration. The amount of vertical dimension was determined based on the diagnostic wax up, and the patient’s adaptation was evaluated by using a removable occlusal splint for 6 weeks. Thereafter, the coordination of the muscular nervous system, aesthetics, temporomandibular joint were re-evaluated for 3 months by restoring the fixed provisional restoration. Through the above treatment process, the final restoration was completed with full mouth fixed prosthesis using monolithic zirconia, and functionally and aesthetically stable results were obtained.

We assessed about growth hormone binding proteins (GHBP) activity which was measured eluted biotin GH fraction with alkaline phosphatase-streptavidine in children with insulin dependent diabetes mellitus (IDDM), short stature due to growth hormone deficiency (GHD), chronic renal failure, short stature due to nutritional deficiency. hypothyroidism and normal control groups using high pressure liquid chromatography protein pak 300 sw column. The following results are observed: 1) There were 3 types of growth hormone (GH) in serum: first GH binded with type I (minor) GHBP suggesting 200K dalton of molecular weight, second GH binded with type II (major) GHBP suggesting 60~70K dalton of molecular weight, and third GH were free form GH suggesting 20~25K dalton of molecular weight. 2) Type II (major) GHBP showed considerable individual variation in all ages. Neonates had the lowest levels of GHBP activity, but by the puberty the levels had increased & remained stable from adolescent to adult periods. 3) GHBP activity of children with IDDM at diagnosis was low value as compared to the same agenormal control group (p<0.05), and difference of GHBP activity among children with IDDM was related with height velocity (r=+0.92). Follow up GHBP activity during insulin therapy was reverse correlation with HbAlc. 4) GHBP activity of children with GHD at diagnosis was a slightly low compared to aged matched control and follow-up GHBP activity after 1 dose GH therapy showed increasing tendency (r=-0.68). 5) Otherwise, children with chronic renal failure, short stature due to nutritional deficiency, and hypothyroidism were assessed lower value than normal control group. Above results, GHBP activity had the lowest levels at neonatal period and then increasing tendency until puberty period and remained steady level until adult period. Regulation of GHBP may be closely related with metabolic control state by insulin, GH, nutritional status, and thyroid hormone..

CHAP syndorme consists of choreoathetosis, orofacial dyskinesia, affective change, hypotonia, and pseudobulbar signs. CHAP syndrome was firstly des- cribed with onset 1 to 7 days after induced profound hypothermia and complete circulatory arrest for con- genital heart lesion repair. Since then, only a few cases have been reported until now. Case We report a patient who demonstrated all of the elements of the CHAP syndrome in severe cachexic state. Brain SPECT(99mTC-ECD) shows decreased perfusion in left fronto-parieto-temporal lobe. Comments The pathogenesis of CHAP syndrome is obscure. However our case led us to suggest that more essential component pre- disposing to the CHAP syndrome is hypoxia rather than hypothermia. Furthermore, it seems to be related with circulatory insufficiency in extrapyramidal nervous systems.

6.A Case of Type II Congenital Cystic Adenomatoid Malformation of the Lung in a Transdiaphragmatic Extralobar Pulmonary Sequestration.
Korean Journal of Obstetrics and Gynecology 2003;46(8):1604-1609
With the current widespread use of obstetric ultrasonography, increasing cases of congenital malformations have been demonstrated antenatally. Both pulmonary sequestration and congenital cystic adenomatoid malformation of the lung (CCAM) are two infrequent congenital pulmonary diseases. The combination of these entities is rare. In the review of literature, this abnormality is so rare that only 80 cases were reported worldwide. To our knowledge, there has been no report that this combined malformation is located transdiaphragmatically. We report the first case of transdiaphragmatic extralobar pulmonary sequestration (ELS) associated with CCAM which was diagnosed by prenatal ultrasonography at 24 weeks gestational age.

Right aortic arch with isolation of the left subclavian artery is a rare anomaly. The incidence of bilateral ductus arteriosus is sporadic, and a right aortic arch with isolation of the left subclavian artery in association with bilateral ductus arteriosus is therefore extremely rare. Since the symptoms and signs of isolation of the left subclavian artery can include the absence or underdevelopment of the left arm, subclavian steal syndrome, or pulmonary artery steal syndrome, the proper therapeutic approach is controversial. We report a case in which surgical reconstruction was used to treat isolation of the left subclavian artery with right aortic arch in association with bilateral ductus arteriosus and a ventricular septal defect.

PURPOSE: In this study, the changes in ocular surface parameters and tear meniscus after strabismus surgery when treated with or without artificial tears were evaluated using optical coherence tomography (OCT). METHODS: The present study included 30 patients who received bilateral lateral rectus recession surgery for exotropia. The patients instilled artificial tear eye drops only in the left eye. Before and 2, 4, 8, and 12 weeks after surgery, tear film break-up time (BUT), Schirmer's test, corneal staining test, tear meniscus height and area were measured using OCT and compared in both eyes. Before and 8 weeks after surgery, conjunctival compression cytology test was performed. RESULTS: The mean patient age was 8.7 years. After 8 weeks, BUT and corneal staining scores were 12.3 ± 1.5 seconds and 1.3 ± 0.4 in patients treated with artificial tears and 9.5 ± 1.0 seconds and 2.0 ± 0.7 in patients not treated with artificial tears (both p < 0.000). Four weeks after surgery, tear meniscus height and area using OCT were 290.2 ± 42.3 µm and 566.7 ± 48.2 pixels in patients treated with artificial tears and 246 ± 45.5 µm and 504.0 ± 29.7 pixels in patients not treated with artificial tears (p = 0.045 and p = 0.019, respectively). Goblet cell count was significantly different between the eyes 8 weeks after surgery (p = 0.033). CONCLUSIONS: Instability of tear meniscus can be detected after strabismus surgery using BUT, Schirmer's test, corneal staining test, tear meniscus height and area, and OCT. After surgery, artificial tears help treat dry eye symptoms by corneo-conjunctival wound healing mechanism and increasing tear meniscus stability.

BACKGROUND: Pulmonary vessels constrict when they are exposed to hypoxia, unlike other vessels. It is hypothesized that the decreased concentration of cAMP in the hypoxic condition causes this reaction, HPV (hypoxic pulmonary vasoconstriction). When cAMP concentration is increased by either activating adenylate cyclase, using adenosine, or inhibiting the cAMP hydrolysing enzyme, phosphodiesterase type 3, using amrinone, then HPV can be reversed. The aims of this study were to develop HPV in an isolated perfused rat lung preparation, and to investigate the vasodilating effects of adenosine and amrinone on HPV. METHODS: Isolated lungs from male rats (270 330 g) were ventilated with a normoxic gas mixture (21%O2-5%CO2-74%N2) or a hypoxic gas mixture (3%O2-5%CO2-92%N2) alternately, and perfused with calcium-containing perfusate solution. Adenosine (6 x 100-2 microgram, n = 6) and amrinone (5 x 101-3 microgram, n = 6) were mixed to perfusate solution, and the initial hypoxic pressor response { Pin = Pmax (maximum pulmonary artery pressure) - Pin (initial pulmonary artery pressure)} and hypoxic pressor responses after drug administration { Pdrug = Pmax (maximum pulmonary artery pressure) - Pbase (baseline pulmonary artery pressure)} were measured. Meclofenamate was used to block prostaglandin-mediated vasorelaxation. RESULTS: Adenosine did not decrease Pdrug compared to Pin. But amrinone inhibited HPV effectively a with a linear dose-response relationship (r = 0.842, P< 0.05). y = 26.72 x log (x) 35.79y: % relaxation = 100 [ Pdrug/ Pin] 100 , x: amount of drug, microgram, CONCLUSIONS: Amrinone attenuated HPV, and it can be concluded that increased levels of cAMP helpful to relax pulmonary vessels in hypoxic condition.
