Abstract
A bidirectional causal relationship has been established between temporomandibular disorders (TMDs) and chronic headaches. Recent advances in the neurobiology of chronic pain offer a framework for understanding the comorbidity between these two conditions that might reside in the shared biomolecular mechanisms of peripheral and central sensitization. The initiation of these processes is inflammatory in nature and is most likely mediated by key molecules, including calcitonin gene-related peptide (CGRP). This scoping review proposes that CGRP-mediated neuroinflammation in the trigeminal ganglion may partly explain the biomolecular bidirectional link between TMDs and chronic headaches. Finally, clinical implications of this neuropathologic process are briefly discussed.

Abstract
Increased concentrations of atmospheric greenhouse gases have led to a global mean surface temperature 1.0°C higher than during the pre-industrial period. We expand on the recent IPCC Special Report on global warming of 1.5°C and review the additional risks associated with higher levels of warming, each having major implications for multiple geographies, climates, and ecosystems. Limiting warming to 1.5°C rather than 2.0°C would be required to maintain substantial proportions of ecosystems and would have clear benefits for human health and economies. These conclusions are relevant for people everywhere, particularly in low- and middle-income countries, where the escalation of climate-related risks may prevent the achievement of the United Nations Sustainable Development Goals.

Abstract
Angiography is the current gold standard for imaging during percutaneous coronary interventions but has significant limitations. Catheter-based intravascular imaging techniques such as intravascular ultrasound and the more recent optical coherence tomography have the potential to overcome these limitations and thus optimize clinical outcomes. In this update, we discussed the current applications of the available imaging techniques, existing evidence, continuing unmet needs, and potential areas for further research.

Abstract
Significant left main coronary artery (LMCA) disease is found in 5–6% of all patients undergoing coronary angiography. It usually presents as acute coronary syndrome and is commonly associated with multi-vessel coronary artery disease (CAD). Complete occlusion of LMCA is a much rarer finding, since these patients usually present as unstable angina, myocardial infarction and cardiogenic shock. We report a case of a young female, who presented with chronic stable angina and had an isolated chronic total occlusion (CTO) of LMCA with no lesions in the other coronary arteries. Aortogram failed to demonstrate the stump of occluded LMCA and demonstrated the filling of the left coronary system from the right coronary artery. Apart from dyslipidemia, she had no other risk factors for CAD. She was extensively evaluated for non-atherosclerotic causes of LMCA CTO including vasculitis. She underwent coronary artery bypass graft successfully without any peri-procedural complications.

Abstract
Background Informed consent is a systematic process for obtaining permission before conducting a healthcare intervention. In a developing country, gaining informed consent is generally perceived to be a ritual only to comply with legal requirements. The present study examined this by assessing the process of informed consent in patients undergoing gastrointestinal surgery or living donor liver transplantation (LDLT) and their relatives, based on their comprehension and overall satisfaction, in India. Methods All patients undergoing any gastrointestinal surgery or LDLT procedure between August 2015 and July 2016 and their relatives were included, and were administered a structured questionnaire 5 days after the procedure. Results The majority of patients (94·2 per cent) could recall the nature of their disease, the surgery performed (81·6 per cent) and anticipated complications (55·6 per cent). Among their relatives, these proportions were 97·8, 87·3 and 58·5 per cent respectively. Recall was associated with age, occupation and education among both patients and relatives. Patients undergoing LDLT, their donors and their relatives had better recall than those who had other gastrointestinal procedures (P < 0·001). Many patients found the process of informed consent useful and reassuring. Conclusion The details and risks of an operation were understood by most of the patients, especially those undergoing liver transplantation. Patients from developing countries can generally understand ‘informed consent’, and value it.

Abstract
This article reviews fluid therapy and medications in pediatric trauma. For resuscitation in the setting of hemorrhagic shock, isotonic crystalloid solution is the first-line agent of choice. Colloid solutions offer no additional benefit, introduce possible increased risks and cost more than crystalloids. Blood products, starting with pRBCs, should be introduced after 20-40 ml/kg of crystalloid has been administered if there is ongoing need for volume replacement. The use of a massive transfusion protocol of 1:1:1 (if >30 kg) or 30:20:20 (if <30 kg) of pRBCs:FFP:platelets is suggested after an initial 30 ml/kg of pRBcs has been administered. Cryoprecipitate should be given for documented low fibrinogen or ongoing bleeding after administration of 1 round of all 3 blood components. For patients at risk of massive hemorrhage, early administration of tranexamic acid with an initial loading dose of 15 mg/kg (maximum 1 g) is recommended. Choice of medication for intubation of the patient with Traumatic Brain Injury (TBI) may best be guided by physiology: in the TBI patient with a high mean arterial pressure, premedication with lidocaine, fentanyl and use of etomidate may be most appropriate, whereas in the hemodynamically compromised patient, use of ketamine alone may be considered. If needed, norepinephrine has been recommended as a temporizing agent for vasopressor support in the setting of fluid-refractory shock. Although controversial, in the setting of significant spinal cord injury, the potential benefits of administering 24-48 hours of steroids (initial 30 mg/kg of methylprednisolone within 8 hours of injury) may outweigh the risks especially in previously healthy pediatric patients.

Abstract
A well-studied RNA-binding protein Hu Antigen-R (HuR), controls post-transcriptional gene regulation and undergoes stress-activated caspase-3 dependent cleavage in cancer cells. The cleavage products of HuR are known to promote cell death however, the underlying molecular mechanisms facilitating caspase-3 activation and HuR cleavage remains unknown. Here, we show that HuR cleavage associated with active caspase-3 in oral cancer cells treated with ionizing radiation and chemotherapeutic drug, paclitaxel. We determined that oral cancer cells overexpressing cyclooxygenase-2 (COX-2) limited the cleavage of caspase-3 and HuR, which reduced the rate of cell death in paclitaxel resistant oral cancer cells. Specific inhibition of COX-2 by celecoxib, promoted apoptosis through activation of caspase-3 and cleavage of HuR in paclitaxel-resistant oral cancer cells, both in vitro and in vivo. In addition, oral cancer cells overexpressing cellular HuR increased the half-life of COX-2 mRNA, promoted COX-2 protein expression and exhibited enhanced tumor growth in vivo in comparison with cells expressing a cleavable form of HuR. Finally, our ribonucleoprotein immunoprecipitation and sequencing (RIP-seq) analyses of HuR in oral cancer cells treated with ionizing radiation (IR), determined that HuR cleavage product-1 (HuR-CP1) bound and promoted the expression of mRNAs encoding proteins involved in apoptosis. Our results indicated that, cellular non-cleavable HuR controls COX-2 mRNA expression and enzymatic activity. In addition, overexpressed COX-2 protein repressed the cleavage of caspase-3 and HuR to promote drug resistance and tumor growth. Altogether, our observations support the use of the COX-2 inhibitor celecoxib, in combination with paclitaxel, for the management of paclitaxel resistant oral cancer cells.

Abstract
Pharmacometricians require three skills to be influential: technical, business (e.g., drug development), and soft skills (e.g., communication). Effective communication is required to translate technical and often complicated quantitative findings to interdisciplinary team members in order to influence drug development or regulatory decisions. In this tutorial, we highlight important aspects related to communicating pharmacometric analysis to influence decisions.

Abstract
Ascending infection of the uterus with Gram-negative bacteria is responsible for postpartum endometritis in cattle and buffalo and can adversely affect fertility. Development of a laboratory animal model for bovine endometritis would facilitate the understanding of the pathogenesis as it is difficult to conduct controlled experimentation in the native host. In the present study, 30 virgin Swiss Albino mice (5-8 weeks old) were used to evaluate the pathogenic potential of Escherichia coli, isolated from the normally calved postpartum buffalo to induce endometritis. Mice in the diestrus phase of the estrous cycle were randomly allotted to one of the following four intravaginal inoculation (100 μL) treatments: EG (experimental group)-1: sterile normal saline; EG-2, -3 and -4: E. coli@ 1.5 × 104, 105 and 106 CFU/ml, respectively. The animals were then scarified 36 h post-inoculation to study gross and microscopical lesions. Gross changes were confined to EG-4. Acute endometritis was recorded in 50% of the EG-3 and 66.7% of the EG-4. The rate of acute endometritis development was significantly higher in EG-4 (P<0.05) as compared to the other groups. The present study demonstrated that the animal model for bubaline endometritis can be developed in mice by intravaginal inoculation of E.coli@ 1.5 × 106 CFU/ml at diestrus. Ease of intravaginal inoculation, apparent absence of systemic involvement and high infective rate are the advantages of the model over other studies.

Abstract
The role of melatonin as a protective neurohormone against restoring cyclicity in summer anoestrous animals in photoperiod species has gained wider acceptance. This study was designed to uncover the evidence the slow-release melatonin (MLT) has on initiation of ovarian cyclicity and conception rate (CR) in summer anoestrous buffaloes. Thus, buffaloes diagnosed as summer anoestrous (absence of overt signs of oestrus, concurrent rectal examination and radioimmunoassay for serum progesterone at 10 days interval) were grouped as untreated (Group I, sterilized corn oil, n = 8) and treated (Group II, single subcutaneous injection of MLT @18 mg/50 kg bwt in sterilized corn oil, n = 20). Animals treated and detected in oestrus were artificially inseminated (AI) followed by division into Group III (second dose of MLT on 5th day post-AI, n = 8) and Group IV (no melatonin administration, n = 10). Blood samples were collected at 4 days interval for estimation of serum MLT, progesterone and oestrogen using radioimmunoassay kit. Mean oestrous induction rate (OIR), oestrous induction interval (OII), interoestrous interval (IOI) and CR were estimated. Compared to control, concentration of melatonin was significantly (p < 0.05) higher in treated group ranging from 14.34 ± 1.72 to 412.31 ± 14.47 pg/ml whereas other two hormones did not show any concentration difference. Melatonin-administered buffaloes showed significantly (p < 0.05) higher (90%) OIR with OII of 18.06 ± 1.57 days. Results showed improvement in conception rate in buffaloes administered with post-insemination melatonin. It can be concluded from the study that slow-release melatonin supplementation restored cyclicity in summer anoestrous animals resulting in improvement in conception rate in buffaloes.

Abstract
OBJECTIVE To develop surface landmarks for blind axillary vein puncture for pacemaker lead implantation. METHODS AND RESULTS Patients for routine coronary angiography were counseled for participating in our study. 20 patients who gave consent were taken up for axillary venogram after proper positioning at the time of coronary angiogram. The venograms of these 20 patients, were reviewed and the landmarks were used to develop a blind axillary puncture technique. Success rate of 100% was achieved with surface landmark guided axillary vein puncture. The implantation time while using surface landmark guided axillary puncture was not significantly longer than when venography based approach was used. Another interesting observation made from the study was that increasing BMI had a positive correlation with the time taken for venous access, the fluoroscopic time and the volume of contrast used, all the associations being statistically significant. Thus, the surface landmark guided technique is more safe and expeditious in non obese patients and probably in pediatric patients as well. Moreover, the new surface landmark guided approach is a significant safety step in terms of reducing the unwanted and avoidable radiation exposure to the hands. CONCLUSION The results of this study demonstrate that placement of endocardial permanent pacemaker and ICD leads via the developed surface landmarks is effective and safe and is devoid of the harmful effects of radiation and contrast exposure.

Abstract
Medicinal plants having immunomodulatory properties provide an alterna-tive potential to conventional chemotherapy for a variety of diseases espe-cially in relation to host defense mechanism. Curcumin one of major curcu-minoids of Curcuma longa, reportedly possess several pharmacological prop-erties including anti-inflammatory, anti-cancer, immunomodulatory activi-ties. Curcumin blocks inflammatory enzymes cyclooxygenase (COX), lipooxy-genase (LOX), matrix metalloproteinase (MMP). Curcumin suppresses the proliferation of a wide variety of tumour cells, including breast carcinoma, colon carcinoma, and renal cell carcinoma through cell cycle arrest. It in-duced apoptosis by downregulation of antiapoptotic protein (Bcl-2 and Bcl-xL). Curcumin modulates immune system by suppressing T-cells, proliferating number of B-cells and reducing proliferation of immature B-cell lymphoma cells. Curcumin treatment inhibited the production of cytokines (IL-8, MIP-1α, MCP-1, IL-1β, TNF-α) and dimerisation of TLR’s. Immunoregulatory activi-ty of curcumin is by inhibiting phosphorylation of IKKβ which ultimately leads to suppression of NF-κB (transcriptional activator protein). This activity of curcumin has renewed scientific interest in its potential to prevent and treat the diseases such as arthritis, allergy, asthma & cancer.

Abstract
This study was undertaken to compare the effect of oxytocin and human chorionic gonadotrophin (hCG) on ovulation and conception. A total of 100 women with anovulatory infertility were allocated into two equal groups to take clomiphene citrate plus hCG or clomiphene citrate plus oxytocin. The size and number of follicles by transvaginal sonography determined the administration of hCG or oxytocin. The serum progesterone concentration was measured to provide evidence for ovulation. The ovulation and pregnancy rate of the two groups were compared. There was no significant difference between the groups with respect to mean number of follicles, mean follicular size and rate of ovulation in three cycles. The rate of pregnancy was higher in the oxytocin group compared with the hCG group (12% vs 4%) but it failed to reach statistical difference (p = 0.140). Mild pain was the only side-effect observed in the two groups. Oxytocin was found to be a viable alternative to hCG for triggering ovulation in infertile patients.

Abstract
Atypical vascular lesions (AVL) and angiosarcomas (AS) are lesions known to arise after radiation therapy. These lesions can show overlap in both their gross and histologic pictures, and distinction between the two can be extremely challenging at times. They are known most commonly to arise in the breast region after radiation therapy. We present the first unique case of post-radiation AVL/AS arising in the larynx of a 51 year old woman, occurring 8 years after she received radiation for tonsillar squamous cell carcinoma.

Abstract
PREAMBLE: The potential risk of contrast-induced acute kidney injury (CI-AKI) has made utilization of coronary angiography in the work-up for the diagnosis of coronary artery disease in CKD quite low.(1) This is in contrast to increasing prevalence and severity of CAD as the serum creatinine rises.(2) In fact most CKD patients will succumb to CAD and not to ESRD.(3) Thus the judicious use of CAG/PCI in this setting is of prime importance but underused. The CSI began to develop guidelines for Indian context as most guidelines are those developed by ACC/AHA or ESC. The aim was to assist the physicians in selecting the best management strategy for an individual patient under his care based on an expert committee who would review the current data and write the guidelines with relevance to the Indian context. The guidelines were developed initially in June 2010 as an initiative of Delhi CSI. Three interventional cardiologist (SB, AS, KKS), one nephrologist (SCT) and two clinical cardiologists (ST, RG) along with Dr. Roxana Mehran (New York) and Dr. Peter McCullough (Missouri), U.S.A.; were involved in a three-way teleconference to discuss/debate the data. This was presented by SB, and over the next two hours each data subset was debated/agreed/deleted and this resulted in the "Guidelines for CAG in Renal Dysfunction Patients". These were then written and re- circulated to all for final comments. Further, these guidelines were updated and additional Task Force Members nominated by Central CSI were involved in the formation of the final CSI Guidelines. Both (Roxana Mehran and Peter McCullough) reviewed these updated Guidelines in October 2012 and after incorporating the views of all the Task Force members-the final format is as it is presented in this final document.

Abstract
Mucocutaneous leishmaniasis has rarely been reported from India. The usual causative organisms of this infection are Leishmania braziliensis and L. tropica. Another species, L. donovani, which usually causes visceral leishmaniasis, has recently been reported to cause mucocutaneous disease in a few patients from Sri Lanka. We report two patients who had undiagnosed chronic skin lesions for several years. Skin biopsies revealed Leishmania and the species was characterized as L. donovani in both patients. There was considerable improvement in the skin lesions following treatment with liposomal amphotericin B.

Abstract
Due to radiation-induced immune depression and development of pathologies such as cancer, there is increasing urgency to identify radiomitigators that are effective when administered after radiation exposure. The main goal of this study was to determine the radiomitigation capacity of MnTE-2-PyP[Mn(III) tetrakis (N-ethylpyridinium-2-yl) porphyrin], a superoxide dismutase (SOD) mimetic, and evaluate leukocyte parameters in spleen and blood. C57BL/6 mice were total-body exposed to 2 Gy γ-rays (Co-60), i.e., well below a lethal dose, followed by subcutaneous implantation of 5 × 10(5) RM-9 prostate tumor cells and initiation of MnTE-2-PyP treatment (day 0); interval between each procedure was 1-2 h. The drug was administered daily (12 times). Tumor progression was monitored and immunological analyses were performed on a subset per group on day 12. Animals treated with MnTE-2-PyP alone had significantly slower tumor growth compared to mice that did not receive the drug (P < 0.05), while radiation alone had no effect. Treatment of tumor-bearing mice with MnTE-2-PyP alone significantly increased spleen mass relative to body mass; the numbers of splenic white blood cells (WBC) and lymphocytes (B and T), as well as circulating WBC, granulocytes, and platelets, were high compared to one of more of the other groups (P < 0.05). The results show that MnTE-2-PyP slowed RM-9 tumor progression and up-regulated immune parameters, but mitigation of the effects of 2 Gy total-body irradiation were minimal.

Abstract
BACKGROUND Chronic fissure in ano is a common distressing problem with high recurrence rates. Any treatment modality should be simple, effective and reversible with no permanent sequelae. Long term medical management with poor compliance or surgical therapy with risk of incontinence are both less than ideal. In this scenario chemical sphincterotomy using Botulinum toxin offers an alternative modality. METHODS A total of 30 patients of chronic fissure in ano were treated with Botulinum toxin injection in the internal sphincter. RESULT All patients had significant symptomatic relief with high rates of fissure healing. The simplicity of administration, lack of complications and cost effectiveness make it a useful alternative to the currently practiced approaches. CONCLUSION Botulinum toxin offers a simple outpatient treatment of chronic fissure in ano, which is safe, cost effective and reversible without significant complication. It has the potential of being used as a first line treatment in chronic fissure in ano.

Abstract
This prospective double blind study was undertaken to compare the safety and efficacy of oral vs vaginal misoprostol in equivalent doses (50 microg) for induction of labour. A total of 128 term pregnancies with indication for induction of labour were allocated to two groups to receive 50 microg misoprostol orally or vaginally, every 4 h until adequate contractions were achieved or a maximum of 200 microg dose. Induction to delivery interval was significantly shorter in the vaginal group compared with the oral group (14.6 h vs 22.5 h; p < 0.001). There was no significant difference between the groups with respect to mode of delivery, neonatal outcome and maternal side-effects. However, the incidence of abnormal contractility pattern was more common in the vaginal group (10/68, 14.6%) as compared with the oral group (4/60, 6.6%) (p = 0.146).
