Parvati Thiruvattar Subramoni,Joanna Philip Saratha 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.7

This paper presents an experimental investigation on the behaviour of Concrete Filled Double Skin Tubular (CFDST) columnconnected to Concrete Filled Steel Tubular (CFST) beam under reversed lateral loading. The CFDST column consists of twoconcentric cold-formed steel tubes with concrete sandwiched between them and the CFST member consist of cold-formed steelhollow section completely filled with concrete. The specimen in this study consists of a hollow square tube as the outer skin for bothCFDST and CFST members. The inner skin of the CFDST column is a circular steel tube and M30 grade concrete having 40%cement replaced with fly ash was filled in between the tubes. The connection between the beams and the columns were providedusing through bolts and angle plates. A pair of specimens considered as the control specimens having CFST members for both beamand column were also tested for comparison. All the four specimens were subjected to a constant axial load and reversed lateralloading which simulates the earthquake forces. The seismic characteristics like hysteretic behavior, peak load displacement, ductility,stiffness degradation and energy dissipation of CFDST beam-column were compared with that of the CFST beam-column. Thebeam-column specimens with CFDST columns exhibited favorable seismic behaviour with reduced self-weight and hence a betterchoice than CFST columns in regions of seismic risk.

Background: Cervical cancer is one of the commonest cancers among women all over the world. The association of cervical cancer with human papilloma virus (HPV) is well established. Knowledge about the causal relationship between HPV and cervical cancer is important to make appropriate, evidence-based health care choices. In this context we conducted a community based study among women about the knowledge, attitude and practice about HPV infections and their health effects. Materials and Methods: A cross sectional interview based house to house survey was conducted with a validated data collection tool covering sociodemographic factors, knowledge, attitude and practice about HPV and its health effects, among 1020 women from a rural village, Perdoor, in Udupi district, Karnataka, India in 2013-14. Results: The mean age of participants was 38.9 years (SD=12.6). Study participants showed a high literacy rate (85.7%). Only 2.4% of sexually exposed women had undergone Pap smear testing. Partners of 4.4%women had undergone circumcision and they belonged to the Muslim community. Male condom usage was reported by 26 women (2.6%). However, none of the participants had heard of HPV and its health effects. Conclusions: This community based study found complete ignorance about HPV among rural South Indian women in spite of a high literacy level.

Background: Cervical cancer is the second commonest cancer among Indian women and its association with human papilloma virus (HPV) is well established. This preventable cancer accounts for the maximum number of cancer related deaths among rural Indian women. Unlike in developed countries there are no organized cervical cancer screening programmes in India due to lack of resources and manpower. Objective: To detect genital HPV infection using urine samples among asymptomatic rural women in the age group of 18-65 years. Materials and Methods: The study area chosen was Perdoor village in Udupi Taluk, Karnataka State and all the women in the age group of 18-65 years formed the study cohort. A cross sectional study was conducted by house visits and 1,305 women were enrolled in the study. After taking written informed consent a data sheet was filled and early stream random urine samples were collected, transported to a laboratory at 4OC and aliquoted. Samples were tested using nested HPV PCR with PGMY09/11 and GP5+/6+ primers. Positive cases were genotyped by sequence analysis. Results: Study participants included 1,134 sexually active and 171 unmarried women with a mean age at marriage of 22.1 (SD=3.9) years. Study area showed high female literacy rate of 86.6%. Five urine samples tested positive for HPV DNA (0.4%). Conclusions: We found very low genital HPV infection rate among women from monogamous community. This is the first major population based study carried out among asymptomatic rural women to detect genital HPV infectio from Karnataka using urine samples.

Expediting venous drainage in large anterolateral thigh flaps for scalp electrical burns in India: two case reports on the use of primary vein grafts for second vein anastomosis

( Jyotica Jagadish Chawaria ),( Parvati Ravula ),( Nazia Tabassum ),( Srikanth Rangachari ) 대한외상학회 2023 大韓外傷學會誌 Vol.36 No.4

Large scalp defects resulting from high-voltage electrical burns require free flaps, preferably skin, to permit optimal coverage and enable future or simultaneous cranial vault reconstruction. The anterolateral thigh permits the harvest of a large area of skin supplied by a reliable perforator. The superficial temporal vessels offer the proximate choice of recipient vessels to enable adequate reach and coverage. The lack of a second vein at this site implies the inability to perform a second venous anastomosis; however, this obstacle can be overcome by using an interposition vein graft, to the neck veins primarily. This assures adequate venous drainage and complete flap survival.

Objectives: The present study was undertaken to study the maternal risk factors for preterm birth (PTB) and low birth weight (LBW) with a special emphasis on assessing the proportions of maternal genitourinary and periodontal infections among Indian women and their association with adverse pregnancy outcomes. Methods: A hospital-based prospective study comprising 790 pregnant women visiting the obstetrics clinic for a routine antenatal check-up was undertaken. Once recruited, all study participants underwent clinical and microbiological investigations for genitourinary infections followed by a dental check-up for the presence of periodontitis. The study participants were followed up until their delivery to record the pregnancy outcomes. Infectious and non-infectious risk factors for PTB and LBW were assessed using univariate and multivariate Cox regression analysis. Independent risk factors for PTB and LBW were reported in terms of adjusted relative risk (ARR) with the 95% confidence interval (CI). Results: Rates of PTB and LBW in the study population were 7.6% and 11.4%, respectively. Previous preterm delivery (ARR, 5.37; 95% CI, 1.5 to 19.1), periodontitis (ARR, 2.39; 95% CI, 1.1 to 4.9), Oligohydramnios (ARR, 5.23; 95% CI, 2.4 to 11.5), presence of Nugent's intermediate vaginal flora (ARR, 2.75; 95% CI, 1.4 to 5.1), gestational diabetes mellitus (ARR, 2.91; 95% CI, 1.0 to 8.3), and maternal height <1.50 m (ARR, 2.21; 95% CI, 1.1 to 4.1) were risk factors for PTB, while periodontitis (ARR, 3.38; 95% CI, 1.6 to 6.9), gestational hypertension (ARR, 3.70; 95% CI, 1.3 to 10.8), maternal height <1.50 m (ARR, 2.66; 95% CI, 1.3 to 5.1) and genital infection during later stages of pregnancy (ARR, 2.79; 95% CI, 1.2 to 6.1) were independent risk factors for LBW. Conclusions: Our study findings underscore the need to consider screening for potential genitourinary and periodontal infections during routine antenatal care in developing countries.

이 연구의 목적은 무릎의 연속돌림영상을 만들어서 무릎 해부학을 익히는 데 도움주는 것이다. 이를 위해서 고정한 시신의 무릎을 여덟 층으로 해부한 다음에 각 층을 5도 간격으로 돌리면서 사진 찍었다. 더불어 무릎관절을 조금씩 굽히면서 사진 찍었다. 각 영상마다 해부구조물의 이름을 붙였다. 이 결과로 한 층에 72개, 총 864개의 연속돌림영상을 만들었다. 같은 방법으로 고정하지 않은 시신의 무릎을 해부한 다음에 돌리면서 사진찍었다. 이 결과로 한 층에 72개, 총 1,296개의 연속돌림영상을 만들었다. 이 연구에서 마련한 무릎연속돌림영상은 무릎 해부학을 익히는 소프트웨어를 만드는 데 도움될 것이다. The purpose of this study is to present the serially rotated images (SRIs) of the dissected knee for the production of educational software of knee anatomy. In order to achieve the purpose, the SRIs of dissected knee were generated as follows. An embalmed knee was serially dissected to make eight layers of the dissected knee. The knee in each layer was serially rotated at every five degree angle and photographed to obtain 72 SRIs. In every SRI, all anatomical structures were annotated. The knee was serially flexed to make additional SRIs. Similar procedures were performed with a fresh knee. The SRIs of knee, prepared in this study, will be used as sources of the software, which will be helpful in educating knee anatomy.

Background: The human papillomavirus (HPV) and its variants show wide geographical distribution and have been reported to cause cervical lesions. With cervical neoplasia as the leading cancer in Indian women, the aim of the present study was to evaluate the multiple infection HPV type distribution and variant genotypes in cervical samples from the coastal Karnataka region, India. Materials and Methods: A total of 212 samples were screened by nested polymerase chain reaction using PGMY9/11 and GP5+/6+ primers. HPV positive samples were sequenced to identify the types and a phylogenetic tree was constructed using the neighbor-joining method. Results: Sequence analysis identified a total of 14 HPV types distributed in 20%, 73.3% and 82.5% of non-malignant, pre-malignant [low grade squamous intraepithelial lesion (LSIL) and high grade squamous intraepithelial lesion (HSIL)] and cervical cancer samples. The distribution of high risk HPV in cancer samples was HPV 16, 76.4%, HPV18, 11.7%, HPV81, 2.9%, HPV31, 1.4%, HPV35, 1.4% and HPV 45, 1.4%. Multiple infections were observed in 11.8% of tumor samples with HPV 16 contributing to 62.5% of cases. In non-malignant samples, 20% of HPV positive samples were detected with HPV16, 82.3%, HPV33, 5.8% and HPV58, 5.8% and very low incidence of multiple infections. Comparative phylogenetic analysis of HPV variants identified 9 HPV sequences as new papillomavirus species, predominantly classified as European lineage type. Conclusions: The findings for HPV infections associated with progression of cervical cancer in coastal Karnataka region and HPV variant analysis provide baseline data for prevention and HPV vaccination programs.
