Assessment of Metabolic Parameters For Autism Spectrum Disorders

Autism is a brain development disorder that first appears during infancy or childhood, and generally follows a steady course without remission. Impairments result from maturation-related changes in various systems of the brain. Autism is one of the five pervasive developmental disorders (PDD), which are characterized by widespread abnormalities of social interactions and communication, and severely restricted interests and highly repetitive behavior. The reported incidence of autism spectrum disorders (ASDs) has increased markedly over the past decade. The Centre for Disease Control and Prevention has recently estimated the prevalence of ASDs in the United States at approximately 5.6 per 1000 (1 of 155 to 1 of 160) children. Several metabolic defects, such as phenylketonuria, are associated with autistic symptoms. In deciding upon the appropriate evaluation scheme a clinician must consider a host of different factors. The guidelines in this article have been developed to assist the clinician in the consideration of these factors

VARIATION OF PEAK EXPIRATORY FLOW RATE WITH BODY MASS INDEX IN THE FIRST YEAR MALE MEDICAL STUDENTS OF VISWABHARATHI MEDICAL COLLEGE, KURNOOL

Background: Obesity has become one of the major health issues in India. WHO defines obesity as “A condition with excessive fat accumulation in the body to the extent that the health and wellbeing are adversely affectedâ€. Obesity results from a complex interaction of genetic, behavioral, environmental and socioeconomic factors causing an imbalance in energy production and expenditure. Peak expiratory flow rate is the maximum rate of airflow that can be generated during forced expiratory maneuver starting from total lung capacity. The simplicity of the method is its main advantage. It is measured by using a standard Wright Peak Flow Meter or mini Wright Meter. The pulmonary disorders due to obesity results in increased mortality and morbidity. Aims: To study the effect of Body Mass Index on Peak Expiratory Flow Rate in Medical students. Methods & Methods: study was performed on 60 Male age group of 17-22 Years, categorized as normal Weight BMI= 18.5-24.99kg/m2 and overweight BMI= 25-29.99 Kg/m2. There were 30 students with normal Weight BMI and 30 students with overweight BMI. Normal weight BMI subjects acted as control group to compare the Peak Expiratory Flow Rate with over weight. The parameters studied were weight, height, age, body mass index and Peak expiratory flow rate (PEFR). Student’s unpaired t-test was used for two group’s comparison. Results: The results of the investigation revealed a significantly lower Peak expiratory flow rate (PEFR) among the overweight BMI subjects compared to normal weight BMI subjects. Conclusion: Thus it is evident from the present study that obesity significantly affects the pulmonary functions which may give rise to long term complications and may lead to early morbidity and mortality.Key words: Peak Expiratory Flow Rate; Body Mass Index; Obesity

Sensor/Control Surface Fault Detection and Reconfiguration using Fuzzy Logic

In the aircraft flight control systems, a quick detection of the faults, that occur in actuators, control surfaces or sensors, is necessary. In this paper, sensor fault detection and reconfiguration is performed using Kalman filter by estimating the states of the plant and comparing them with respective measured values from the sensors. Sensor fault detection and reconfiguration is carried out using non-model-based fuzzy logic technique. Control surface fault detection and reconfiguration is carried out by identifying the elements of control distribution matrix using extended Kalman filter and fuzzy logic. In estimating the factor of effectiveness of the control surface using fuzzy logic, different implication methods such as Mamadani's minimum, Larsen's product, bounded product and drastic product have been used and a comparison is made.Defence Science Journal, 2010, 60(1), pp.76-86, DOI:http://dx.doi.org/10.14429/dsj.60.11

Demonstrating Antenna Miniaturisation for Radiolocation Applications using Double Elliptical Patches

Double Elliptical Micro-strip Patch Antenna (DEMPA) is developed out of Double Elliptical Patch (DEP) which is a recently proposed shape of patch. The use of DEP results in higher flexibility in design of patch antenna and thus promotes antenna miniaturisation. The present work is an attempt to demonstrate the miniaturisation of radiolocation antenna through the concept of Design Flexibility (DF). In this paper, optimised neural network model for synthesis of DEMPA has been developed for radiolocation applications for which the earmarked frequency band is 8.50 GHz – 10.50 GHz. With the help of synthesis model, for an arbitrary operational frequency of 9.85 GHz, radiolocation antennas with effective patch area ranging from 142 mm2 to 66 mm2 were designed by using DEPs. In this case, the percentage reduction in effective patch area was found to be 53.52%. It shows that double elliptical patches can be employed to develop miniaturised radiolocation antennas. One prototype antenna was fabricated and tested to demonstrate the efficacy of the methodology adopted. The fabricated antenna had resonance at 10.15 GHz with a reflection coefficient of -20.73dB and bandwidth of 3.106 GHz (from 7.458 GHz to 10.564 GHz). Its Fractional Bandwidth was 34.469%. Positive and reasonably good gain was maintained over the entire working band. At resonance, the peak gain was 4.22 dB.The measured characteristics of antenna were in close agreement with the simulated results. The methodology presented in this paper can also be applied to frequency bands for other wireless applications

Large chorangiomas: a seven years study in a tertiary care obstetrics and gynaecology hospital

Background: Chorangioma is a benign vascular placental tumour. It is composed of fetal capillary proliferation within the chorionic villi supported by a variable stroma. Smaller lesions are incidental, are often missed and carry no clinical significance. Larger lesions are associated with feto-maternal complications and are infrequently sent for histopathological examination.Methods: The study was conducted at the department of pathology, at a tertiary care obstetrics and gynaecology hospital. The study was a retrospective study which covered 7 years. Paraffin embedded blocks of placental specimens containing mass were taken up for the study. Sections were stained with haematoxylin and eosin (H and E). The results are compared and correlated with clinicopathologic factors. The statistical data are analysed manually.Results: A total of seven cases were included in the study, 4 cases were primi gravida, 1 case each in second, third and fourth gravida. Pregnancy outcome was intrauterine death in 1 case, dead born in 1 case, alive healthy children in 5 cases, birth weight was normal in 4 children, low birth weight in 2 children and 1 was extremely low birth weight. Of the total of 7 placental specimens 3 showed extraplacental mass and rest 4 showed intraplacental mass. All cases showed solitary lesions and measured > 5cm (large). Histopathological examination of all 7 specimens showed features of chorangioma.Conclusions: Careful inspection of the placenta is necessary following all deliveries. Any suspicious lesions should be documented and evaluated by histopathological examination there by predicting feto maternal complications and help the clinicians in better management of the mother and child accordingly. Meagre documentation of such cases prompted us to present this series of 7 cases of large chorangiomas with a mixed fetal outcome

Review of maternal mortality in a tertiary care urban teaching hospital: 10 year retrospective study

Background: The objectives of this study were to calculate the maternal mortality ratio, causes for maternal death in our institution and the duration of hospital admission to death interval.Methods: The study included collecting and analyzing the details of maternal death in women who were admitted to St. Johns Medical College Hospital, Bengaluru, from January 2007 to December 2016. Results: Total maternal deaths were 61 and live births were 26,001 during the study period. The maternal mortality ratio (MMR) was 234.6 per 100,000 live births. Majority of maternal deaths occurred in women aged 18 - 35 years 56 (91.80%) women, primipara 45 (73.77%) and referred cases to our institution from other hospitals 52 (85.24%).                      Most of the women died in the postnatal period 54 (88.52%). Direct obstetric causes accounted for 44 (72.13%) maternal deaths and indirect causes 17 (27.86%) deaths. Preeclampsia and eclampsia were the leading causes for death 13 (21.31%) followed by acute fatty liver of pregnancy 12 (19.67%), hemorrhage 7 (13.11%) and sepsis 6 (9.83%). Anemia was present in 77.04% of women at the time of admission to our hospital. Thirty six (59.01%) women died within a week of admission to the hospital, in which 13 (21.31%) women died in less than 24hours of admission. Twenty five (40.98%) women died after a week of admission to hospital.Conclusions: Apart from the triad of preeclampsia, obstetric haemorrhage and sepsis, acute fatty liver of pregnancy has emerged as an important cause of maternal death. Most of the maternal deaths are preventable. Early detection of complications and timely referral to tertiary care hospital in St. Johns Medical College Hospital, Bengaluru, Karnataka, India decreases maternal morbidity and mortality

A clinical study to evaluate the effect of Dashamoola Trivrit Taila Paana in Kashtartava w.s.r. Dysmenorrhoea

Dysmenorrhoea means difficult menstruation but the term is used to mean painful menstruation, but a more practical definition includes cases of painful menstruation of sufficient magnitude so as to incapacitate day to day activities.[1] Kashtartava is Pratyama Laxana of various Yonivyapads like - Vatala, Paripluta, Udavartini, Mahayoni, Antarmukhi, Sukimukki and also in Vataja Artava Dhushti, Khsina Artava Dhushuti, Asrgdara that affects approximately 50% of menstruating women. It is common reason for losing time at school or work or for visiting the family doctor. Pain is the biggest problem since the beginning of mankind. Morbid Vata Dosha especially Apana Vata is causative factor of Kashtartava. Drugs which have Vatahara Artava Doshahara properties are beneficial.

Ameliorative effect of ethanolic extract of roots of Tetracera akara (Burm. f.) Merr. on D-galactosamine induced hepatotoxicity in Wistar rats by downregulation of inflammatory mediators like TNFα, COX-2 and iNOS

161-171Tetracera akara, a climbing shrub locally called Nennalvalli or Pattuvalli, is an ethnomedicinal plant used by Kani tribe of Kerala to treat chronic liver disorders and inflammatory conditions.  The present study was aimed to evaluate the hepatoprotective activity of ethanolic extract of roots of Tetracera akara root on D-Galactosamine induced hepatotoxicity in Wistar rats. Hepatotoxicity was induced in Wistar rats by intraperitoneal injection of D-GalN (400 mg/kg in saline) in Wistar rats. Ethanolic extract of T. akara root (TA ETH) was administered to the experimental rats in varying doses of (50, 150 and 300 mg/kg/day), p. o. for 7 days. The hepatoprotective effect was evaluated by the estimation of biochemical markers of hepatic injury, anti-oxidant status of the liver by estimating hepatic catalase, superoxide dismutase, glutathione and malondialdehyde, gene and protein expression level of inflammatory marker genes and histopathological evaluation of experimental animals. Administration of TA ETH (150 and 300 mg/kg) significantly (P ≤0.05) restored the levels of serum bilirubin, protein and other hepatic enzymes almost comparable to the standard drug Silymarin-treated groups. The levels of antioxidant enzymes like SOD and CAT were elevated and lipid peroxidation was inhibited as evident from the reduced levels of MDA. The gene expression studies by quantitative PCR method showed that TA ETH significantly (P ≤0.05) downregulated pro inflammatory cytokines, inflammatory COX-2 genes and upregulated IL 10 gene levels in D-GalN induced liver tissue, which was further confirmed in protein estimation by ELISA method. The histopathological observations were in correlation with the biochemical findings showing the presence of normal hepatic architecture, which further evidenced the hepatoprotective effect of TA ETH. Ethanolic extract of the root of T. akara possesses significant hepatoprotective activity mainly by scavenging reactive free radicals, boosting the endogenous antioxidant system in liver and inhibiting pro-inflammatory mediator like TNF α, COX-2, iNOS and promoting the anti-inflammatory IL 10, thus substantiating the tribal claim
