    The present study attempts to know the attitude of secondary school students towards their school climate. It explores their attitude with reference to certain demographic variables like gender, medium of instruction in the school and educational level of parents. The study has been conducted on the sample of 358 students studying at various secondary level schools of India. The tool of Hatboro-Horsham (2008) was adapted to meet the requirement of the present study. The findings of the study revealed that there is a significant difference in the attitude of secondary school students with reference to their gender and medium of instruction. However, no difference has been found in the attitude of secondary school students towards school climate in relation to their parental education.

    This study aims at the development of a safe and effective formulation to counter the effects of lethal irradiation. The sub-fraction (G-001M), prepared from Podophyllum hexandrum has rendered high degree of survival (>90%) at a dose of 6 mg kg−1 body weight (intramuscular) in lethally irradiated mice. Therapeutic dose of G-001M, at about 20 times lower concentration than its LD100, has revealed a DRF of 1.62. Comet assay studies in peripheral blood leukocytes have reflected that, treatment of G-001M before irradiation has significantly reduced DNA tail length (P < .001) and DNA damage score (P < .001), as compared to radiation-only group. Spleen cell counts in irradiated animals had declined drastically at the very first day of exposure, and the fall continued till the 5th day (P < .001). In the treated irradiated groups, there was a steep reduction in the counts initially, but this phase did not prolong. More than 60% decline in thymocytes of irradiated group animals was registered at 5 h of irradiation when compared with controls, and the fall progressed further downwards with the similar pace till 5th day of exposure (P < .001). At later intervals, thymus was found fully regressed. In G-001M pre-treated irradiated groups also, thymocytes decreased till the 5th day but thereafter rejuvenated and within 30 days of treatment the values were close to normal. Current studies have explicitly indicated that, G-001M in very small doses has not only rendered high survivability in lethally irradiated mice, but also protected their cellular DNA, besides supporting fast replenishment of the immune system

    Background Post-partum haemorrhage is the leading cause of maternal death worldwide. Early administration of tranexamic acid reduces deaths due to bleeding in trauma patients. We aimed to assess the effects of early administration of tranexamic acid on death, hysterectomy, and other relevant outcomes in women with post-partum haemorrhage. Methods In this randomised, double-blind, placebo-controlled trial, we recruited women aged 16 years and older with a clinical diagnosis of post-partum haemorrhage after a vaginal birth or caesarean section from 193 hospitals in 21 countries. We randomly assigned women to receive either 1 g intravenous tranexamic acid or matching placebo in addition to usual care. If bleeding continued after 30 min, or stopped and restarted within 24 h of the first dose, a second dose of 1 g of tranexamic acid or placebo could be given. Patients were assigned by selection of a numbered treatment pack from a box containing eight numbered packs that were identical apart from the pack number. Participants, care givers, and those assessing outcomes were masked to allocation. We originally planned to enrol 15 000 women with a composite primary endpoint of death from all-causes or hysterectomy within 42 days of giving birth. However, during the trial it became apparent that the decision to conduct a hysterectomy was often made at the same time as randomisation. Although tranexamic acid could influence the risk of death in these cases, it could not affect the risk of hysterectomy. We therefore increased the sample size from 15 000 to 20 000 women in order to estimate the effect of tranexamic acid on the risk of death from post-partum haemorrhage. All analyses were done on an intention-to-treat basis. This trial is registered with ISRCTN76912190 (Dec 8, 2008); ClinicalTrials.gov, number NCT00872469; and PACTR201007000192283. Findings Between March, 2010, and April, 2016, 20 060 women were enrolled and randomly assigned to receive tranexamic acid (n=10 051) or placebo (n=10 009), of whom 10 036 and 9985, respectively, were included in the analysis. Death due to bleeding was significantly reduced in women given tranexamic acid (155 [1·5%] of 10 036 patients vs 191 [1·9%] of 9985 in the placebo group, risk ratio [RR] 0·81, 95% CI 0·65–1·00; p=0·045), especially in women given treatment within 3 h of giving birth (89 [1·2%] in the tranexamic acid group vs 127 [1·7%] in the placebo group, RR 0·69, 95% CI 0·52–0·91; p=0·008). All other causes of death did not differ significantly by group. Hysterectomy was not reduced with tranexamic acid (358 [3·6%] patients in the tranexamic acid group vs 351 [3·5%] in the placebo group, RR 1·02, 95% CI 0·88–1·07; p=0·84). The composite primary endpoint of death from all causes or hysterectomy was not reduced with tranexamic acid (534 [5·3%] deaths or hysterectomies in the tranexamic acid group vs 546 [5·5%] in the placebo group, RR 0·97, 95% CI 0·87-1·09; p=0·65). Adverse events (including thromboembolic events) did not differ significantly in the tranexamic acid versus placebo group. Interpretation Tranexamic acid reduces death due to bleeding in women with post-partum haemorrhage with no adverse effects. When used as a treatment for postpartum haemorrhage, tranexamic acid should be given as soon as possible after bleeding onset.

    Expanding the clinical phenotype of individuals with a 3-bp in-frame deletion of the NF1 gene (c.2970_2972del): an update of genotype–phenotype correlation

    Get PDF
    Purpose: Neurofibromatosis type 1 (NF1) is characterized by a highly variable clinical presentation, but almost all NF1-affected adults present with cutaneous and/or subcutaneous neurofibromas. Exceptions are individuals heterozygous for the NF1 in-frame deletion, c.2970_2972del (p.Met992del), associated with a mild phenotype without any externally visible tumors. Methods: A total of 135 individuals from 103 unrelated families, all carrying the constitutional NF1 p.Met992del pathogenic variant and clinically assessed using the same standardized phenotypic checklist form, were included in this study. Results: None of the individuals had externally visible plexiform or histopathologically confirmed cutaneous or subcutaneous neurofibromas. We did not identify any complications, such as symptomatic optic pathway gliomas (OPGs) or symptomatic spinal neurofibromas; however, 4.8% of individuals had nonoptic brain tumors, mostly low-grade and asymptomatic, and 38.8% had cognitive impairment/learning disabilities. In an individual with the NF1 constitutional c.2970_2972del and three astrocytomas, we provided proof that all were NF1-associated tumors given loss of heterozygosity at three intragenic NF1 microsatellite markers and c.2970_297

    Multiple vascular anomalies and refractory pericardial effusion in a young patient with Cantu syndrome: a case report and review of the literature

    No full text
    Abstract Background Cantu syndrome is a rare and complex multisystem disorder characterized by hypertrichosis, facial dysmorphism, osteochondroplasia and cardiac abnormalities. With only 150 cases reported worldwide, Cantu syndrome is now gaining wider recognition due to molecular testing and a growing body of literature that further characterizes the syndrome and some of its most important features. Cardiovascular pathology previously described in the literature include cardiomegaly, pericardial effusion, vascular dilation and tortuosity, and other congenital heart defects. However, cardiovascular involvement is highly variable amongst individuals with Cantu syndrome. In some instances, it can be extensive and severe requiring surgical management and long term follow up. Case presentation Herein we report a case of a fourteen-year-old female who presented with worsening pericardial effusion of unknown etiology, and echocardiographic findings of concentric left ventricular hypertrophy, a mildly dilated aortic root and ascending aorta. Her medical history was notable for hemoptysis and an episode of pulmonary hemorrhage secondary to multiple aortopulmonary collaterals that were subsequently embolized in early childhood. She was initially managed with Ibuprofen and Colchicine but continued to worsen, and ultimately required a pericardial window for the management of refractory pericardial effusion. Imaging studies obtained on subsequent visits revealed multiple dilated and tortuous blood vessels in the head, neck, chest, and pelvis. A cardiomyopathy molecular studies panel was sent, and a pathogenic variant was identified in the ABCC9 gene, confirming the molecular diagnosis of autosomal dominant Cantu syndrome. Conclusions Vascular anomalies and significant cardiac involvement are often present in Cantu syndrome, however there are currently no established screening recommendations or surveillance protocols in place. The triad of hypertrichosis, facial dysmorphism, and unexplained cardiovascular involvement in any patient should raise suspicion for Cantu syndrome and warrant further investigation. Initial cardiac evaluation and follow up should be indicated in any patient with a clinical and/or molecular diagnosis of Cantu syndrome. Furthermore, whole body imaging should be utilized to evaluate the extent of vascular involvement and dictate long term monitoring and care

    Introduction: Endometrial cancer is the seventh most common cancer in women worldwide with Age Standardised Incidence Rate (ASIR) of 8.4 per lac. In Indian subcontinent, the incidence is lesser and the ASIR is 2.1/100,000 women. However, its incidence is on the steady rise in developing part of the world including India. Surgery is the primary treatment and adjuvant radiotherapy is given in patients with high-risk of recurrence and significant change has happened in the management in the last 20 years. From India limited literature is available for management practices for endometrial cancer. Aim: To assess the referral patterns, demography, staging, surgical practices, adjuvant treatment and follow-up policies for endometrial cancer in a tertiary care hospital in northern India. Materials and Methods: A retrospective cross-sectional study was done for patients having endometrial cancer treated between January 2000- December 2015 in a tertiary care hospital in northern India in January 2022. A total of 93 patients having endometrial cancer were referred for radiotherapy. For these patients, their referral patterns, demography, staging, surgical practices, adjuvant treatment and follow-up policies were analysed, retrospectively. Disease Free Survival (DFS) and Overall Survival (OS) were computed by Kaplan-Meier method. Results: The median age at presentation was 55 years. Postmenopausal vaginal bleeding was the commonest symptom 78 (83.87%). Ultrasonography 23 (24.73%) was the preferred first imaging modality. Type 1 endometroid carcinoma was 75 (80.64%) and total abdominal hysterectomy with bilateral salpingo-oophrectomy was done in 82 (88.17%). Adjuvant External Beam Radiotherapy (EBRT) with Brachytherapy (BT) was given in 61 (65.59%), EBRT alone in 7(7.52%) and BT alone given in 11 (11.83%). Median EBRT dose was 50.4 Gy. Vaginal cylinder applicator was used in 69 (95.83%) out of 72 patients receiving BT. A 6.0 Gy/# to a total of 2 fractions were given in 57 (79.16%). Median treated length of vagina was 3 cm (range 2-8 cm). Five year DFS and OS was 25% and 25% and 64% and 62% respectively in worst and best case scenario. Ten (10.75%) patients, all having high-risk had multiple visceral and local recurrence. Conclusion: In patients with endometrial cancer, total abdominal hysterectomy with bilateral salpingo-oophrectomy is commonest surgical practice with adjuvant radiotherapy in high-risk patients. In a developing country like India, assuring uniformity of treatment protocols is a challenging task

    Delineation of various target volumes using contrast-enhanced magnetic resonance imaging (MRI) and/or computed tomography (CT) constitutes the primary step for radiation therapy planning (RTP) in brain tumors. This study presents a quantification and comparative evaluation of the various clinical target volumes (CTV) and gross target volumes (GTV) as outlined by contrast-enhanced CT and MRI, along with its implications for postoperative radiotherapy of brain tumors. Twenty-one patients of gliomas were considered for this prospective study. Peritumoral edema as CTV and residual tumor as GTV were delineated separately in postoperative contrast-enhanced CT and MRI. These volumes were estimated separately and their congruence studied for contrast-enhanced CT and MRI. Compared to MRI, CT underestimated the volumes, with significant differences seen in the mean CTV (mean \ub1 SD: 1262.92 \ub1 93.99 cc; P = 0.006) and GTV (mean \ub1 SD: 1221.08 \ub1 36.04 cc; P = 0.014). These differences were found to be significant for high-grade gliomas (CTV: P = 0.045; GTV: P = 0.044), while they were statistically insignificant for low-grade gliomas (CTV: P = 0.080; GTV: P = 0.117). The mean differences in the volumes for CTV and GTV were estimated to be 12106.7% and 1262.6%, respectively, taking the CT volumes as the baseline. Thus, even though, electron density information from CT is essential for RTP, target delineation during postoperative radiotherapy of brain tumors, especially for high-grade tumors, should be based on MRI so as to avoid inadvertent geographical misses, especially in the regions of peritumoral edema

    58-64A number of samples of silver phosphate glasses doped with 1%, 5%, 10% and 20% zinc and cadmium halides were prepared. Control samples of undoped silver phosphate glasses were also prepared. These glasses were characterized by X-ray diffraction, IR spectra, ion transport, and DSC studies. The Tg values obtained from DSC curves were found to increase with increasing concentration of the dopants (Zn/CdX2) where X= Cl, Br, I in all the cases. The Tg and the conductivity values of all the samples of silver phosphate glasses show the following trend: Tg (CdX2) > Tg (ZnX2); X = Cl or Br or I; Tg ( MCl2 ) > Tg (MBr2) > Tg (MI2); M = Cd or Zn; σ (MI2) > σ (MBr2) > σ (MCl2); M = Cd or Zn. These results have been discussed and explained on the basis of changes in the structure of the glass matrix by the addition of the halide ions of different sizes, IR spectra and ion transport studies
