Krishnappa Amita,S. Vijay Shankar,Kuchangi C. Nischal,Haleuoor B. Basavaraj 대한병리학회 2013 Journal of Pathology and Translational Medicine Vol.47 No.1

Benign triton tumors (BTT) are very rare lesions composed of mature skeletal muscle and neural tissue. We report a case of a 14-year-old boy who presented with asymptomatic swelling of the chin over an 18-month duration which increased gradually to involve the left side of the lower lip. Clinically, a diagnosis of neurofibroma was made. Excisional biopsy confirmed the diagnosis of a BTT. Having an affinity for large nerve trunks like the brachial and sciatic, these tumors rarely occur in the head and neck region. When they do, they may involve the large central cranial nerve trunk and present as intracranial masses or involve the smaller peripheral nerve twigs and present as asymptomatic skin nodules, of which only four cases involving peripheral nerves are reported in the English literature. Here, we report the fifth documented case of a BTT involving the mental branch of the trigeminal nerve. A brief review of the literature is also provided.

Long-Term Minute-Wise Wind Forecasting using Time Series Modelling

Harish Krishnappa 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.8

With innovations in technology, alternate energies like solar and wind are becoming more popular. Utilities in some parts of the world rely on Wind energy over coal or gas fired power. Wind energy output is highly mercurial in nature, it changes rapidly even within the course of minutes. Hence, power system operators have to predict changes of the wind power production in order to schedule the Spinning reserve capacity and to manage the grid operations. To reduce the reserve capacity and increase the wind power penetration, the accurate forecasting of wind speed is needed. In addition, wind power forecasting plays an important role in the allocation of balancing power. Although the prediction accuracy of wind power forecasting is lower than the prediction accuracy of load forecasting, wind power forecasts still play a key role to address the operation challenges in electricity supply. This paper deals with Long-term forecast of wind energy for the state grid of Karnataka by employing a simple time series multiplicative modelling. Wind energy production is predicted for the year 2015 using the data collected from 2011-2014.

Background: With increase in life expectancy, adoption of newer lifestyles and screening using prostate specific antigen (PSA), the incidence of prostate cancer is on rise. Globally prostate cancer is the second most frequently diagnosed cancer and sixth leading cause of cancer death in men. The present communication makes an attempt to analyze the time trends in incidence for different age groups of the Indian population reported in different Indian registries using relative difference and regression approaches. Materials and Methods: The data published in Cancer Incidence in Five Continents for various Indian registries for different periods and/or publications by the individual registries served as the source materials. Trends were estimated by computing the mean annual percentage change (MAPC) in the incidence rates using the relative difference between two time periods (latest and oldest) and also by estimation of annual percentage change (EAPC) by the Poisson regression model. Results: Age adjusted incidence rates (AAR) of prostate cancer for the period 2005-2008 ranged from 0.8 (Manipur state excluding Imphal west) to 10.9 (Delhi) per $10^5$ person-years. Age specific incidence rates (ASIR) increased in all PBCRs especially after 55 years showing a peak incidence at +65 years clearly indicating that prostate cancer is a cancer of the elderly. MAPC in crude incidence rate(CR) ranged from 0.14 (Ahmedabad) to 8.6 (Chennai). Chennai also recorded the highest MAPC of 5.66 in ASIR in the age group of 65+. Estimated annual percentage change (EAPC) in the AAR ranged from 0.8 to 5.8 among the three registries. Increase in trend was seen in the 55-64 year age group cohort in many registries and in the 35-44 age group in Metropolitan cities such as Delhi and Mumbai. Conclusions: Several Indian registries have revealed an increasing trend in the incidence of prostate cancer and the mean annual percentage change has ranged from 0.14-8.6.

Purpose: To evaluate the preoperative and intraoperative risk factors for revision after artificial urinary sphincter (AUS) implantation in male patients with stress urinary incontinence (SUI). Methods: A retrospective analysis from a prospectively maintained database was performed. Male patients, with moderate-tosevere SUI, undergoing AUS implantation were included. All patients underwent placement of AMS 800. Cause of revision, type of revision, and time to revision were recorded. Multivariable analyzes were performed using a logistic regression to investigate the risk factors. Competing risk analysis according to Fine-Gray model was used to study time to event data. Results: A total of 70 patients were included. Revision surgery was performed in 22 of 70 patients (31.4%), after a median (interquartile range) time of 26.5 months (6.5–39.3 months). Overall, 19 of 22 repairs (86.4%) and 3 of 22 explants (13.6%) were recorded. Mechanical dysfunction, urethral erosion, urethral atrophy, and device infection were the causes of revision in 11 of 22 (50.0%), 6 of 22 (27.3%), 3 of 22 (13.6%), and 2 of 22 patients (9.1%). Vesicourethral anastomosis stenosis (P=0.02), urethral cuff size of 3.5 cm (P=0.029), and dual implantation (P=0.048) were independent predictors for revision. Vesicourethral anastomosis stenosis (P=0.01) and urethral cuff size of 3.5 cm (P=0.029) predicted a lower survival of the AUS. Conclusions: The vesicourethral anastomosis stenosis, urethral cuff size of 3.5 cm, and dual implantation are independent predictors for revision after AUS implantation. However, only the vesicourethral anastomosis stenosis and urethral cuff size of 3.5 cm predict a lower survival of AUS.

Antifungal efficacy of Azotobacter nigricans on Fusarium infection, total seedlings mass,root and shoot length, and seed germination in maize, sorghum, and wheat were investigated. Antifungal efficacy of A. nigricans against Fusarium sporotrichioides, Fusarium graminearum, Fusariumpoae and Fusarium equiseti showed a significant reduction in growth and Fusarium infection incidence(up to 50%) in all the three treated cereals. However, challenge inoculation of Fusarium spp. to thethree cereals showed 100% infection incidence. Total mass of the maize seedlings increased two foldby A. nigricans treatment; however, only a slight increase was observed in sorghum and wheatseedlings. The highest vigour index recorded in maize was 1321 against Fusarium crookwellense,1616.71 against Fusarium sporotrichioides in sorghum, and 1584.8 against Fusarium acuminatum inwheat treated with A. nigricans. Highest germination incidence of 64% was in maize, 67% in sorghum,and 56% in wheat treated with A. nigricans.

Objectives: The quality of life declines gradually as women enter menopause, owing to the various problems associated with estrogen deficiency and aging, which adds to their morbidities. This study aimed to investigate the patterns of morbidity among rural menopausal women and compare the morbidity patterns among menopausal transition group and post-menopausal women. Methods: This community-based cross-sectional study included menopausal women aged 45-55 years from rural areas of the Etawah district, Uttar Pradesh, India. To select blocks and villages of the district, multistage random sampling was performed. According to a pretested, semistructured schedule, data were collected through interviews. Results: A total of 315 women participated in the study. The most frequent complaints among the participants were of feeling tired and worn out (85.1%) and of muscle and joint pains (67.6%). Poor memory (P = 0.046) and diabetes (P = 0.024) were more common in women who were in the menopause transition phase than in those who were in the postmenopausal phase. Conclusions: This study showed that majority of the menopausal women suffered from physical problems. Lifestyle modification and awareness programs will be beneficial among women in menopausal transition, to reduce the morbidity later in post-menopausal stage. Behaviour change communication, family and community support are essential in post-menopausal women, to help them cope with various morbid conditions.
