Relationship Between Severity of Ischemia and Coronary Artery Disease for Different Stress Test Modalities in the ISCHEMIA Trial.

Background: The relationship between the extent and severity of stress-induced ischemia and the extent and severity of anatomic coronary artery disease (CAD) in patients with obstructive CAD is multifactorial and includes the intensity of stress achieved, type of testing used, presence and extent of prior infarction, collateral blood flow, plaque characteristics, microvascular disease, coronary vasomotor tone, and genetic factors. Among chronic coronary disease participants with site-determined moderate or severe ischemia, we investigated associations between ischemia severity on stress testing and the extent of CAD on coronary computed tomography angiography.

Methods: Clinically indicated stress testing included nuclear imaging, echocardiography, cardiac magnetic resonance imaging, or nonimaging exercise tolerance test.

Evaluation of Improvement in Chronic Rhinosinusitis After Endoscopic Sinus Surgery Using Sino-Nasal Outcome Test-22 (SNOT22) Symptom Score.

Sino-Nasal Outcome Test (SNOT-22) symptom score is the most widely used questionnaire due to its easy interpretation with respect to quality of life (QOL) in patients with chronic rhinosinusitis (CRS). It helps in deciding further treatment plan in patients with refractory CRS despite maximal medical therapy (MMT). Endoscopic sinus surgery (ESS) is suggested in patients not responding to medical treatment.

High-sensitivity troponin I for cardiovascular risk stratification in the general asymptomatic population: Perspectives from Asia-Pacific.

Cardiac troponin is a sensitive and specific biomarker for acute myocardial injury and has been used in the diagnosis of acute coronary syndromes, and has emerged as a tool for identifying high risk individuals for primary preventive therapy. Recent evidence has emerged indicating that high-sensitivity cardiac troponin assays, which allow robust detection of very low troponin concentrations, could detect subclinical injury in asymptomatic patients. On 24 March 2018, a group of cardiologists from the Asia Pacific region convened to review the data and discuss the potential utility of high-sensitivity troponin I (hsTnI) in the risk assessment of cardiovascular disease in the general population.

A study on the impact of CYP2C19 genotype and platelet reactivity assay on patients undergoing PCI.

Background: A thorough understanding of the patient's genotype and their functional response to a medication is necessary for improving event free survival. Several outcome studies support this view particularly if the patient is to be started on clopidogrel due to the prevalence of clopidogrel resistance. Such guided therapy has reduced the incidence of Major Adverse Cardiac Events (MACE) after stent implantation.

Genetics of coronary artery disease - a clinician's perspective.

Coronary artery disease (CAD) is the major cause of fatality and disability among all cardiovascular diseases (CVD). Intricate interactions of genes and environment dictate the outcomes of CAD. Technological advances in the different fields of genetics including linkage studies (LS), candidate gene studies (CGS) and genome-wide association studies (GWA studies) have augmented the knowledge of pathogenesis of CAD.

Chondroradionecrosis of larynx a delayed complication of radiotherapy: management and review of literature.

Unlabelled: Background/objectives Chondroradionecrosis (CRN) of the larynx is a rare and grave complication of radiotherapy which can be fatal if not managed aggressively. A recent trend towards organ preservation protocols towards even advanced stage laryngeal malignancies and with further advances in terms of technology and safety radiation as external beam and intensity modulated varieties are preferred for certain stages of squamous cell carcinomas. Materials and methods We are reporting a series of 4 cases of CRN of the larynx treated in our hospital with 3 cases of stage III carcinoma glottis and one stage III carcinoma supraglottis with no nodal metastasis.

Xeroderma pigmentosum: clinicopathological review of the multiple oculocutaneous malignancies and complications.

Multiple oculo-cutaneous malignancies are a common manifestation on sun-exposed facial areas in patients with Xeroderma pigmentosum (XP). Commonly seen are the basal cell carcinoma and the squamous cell carcinomas which manifest in the early first decade in contrast to fifth and sixth decade in the general population. XP manifests as photosensitivity, hyperpigmentation, premature skin aging and malignant changes like squamous cell carcinoma, basal cell carcinoma, fibrosarcoma and rarely malignant melanoma as well as internal malignancies.

Anatomic and mechanical considerations in restoring volume of the face with use of hyaluronic acid fillers with a novel layered technique.

Context: Facial fillers have revolutionized the field of cosmetic facial rejuvenation as it has become the prime sought - after rejuvenation procedure offering youthful, 3-dimensional look with minimal invasiveness. Fillers are expensive and need to be redone periodically hence a sound understanding of structural basis on which they are laid is important in reducing the quantity of filler required in each sitting as well as increasing the longevity of results.

Aim: The aim of the following study is to analyse a novel method of facial filling "The pillars pyramids and tie beams (PPT)" technique and its advantages over the conventional methods.

Endonasal DCR with Silicon Tube Stents: A Better Management for Acute Lacrimal Abscesses.

Acute dacryocystitis, or inflammation of the lacrimal sac with lacrimal abscess, is almost always secondary to nasolacrimal duct obstruction. The standard practice for the treatment is incision and drainage because of concerns about the risks of exacerbation and spread of infection. Here we tried to evaluate primary EnDCR as a treatment for acute dacryocystitis with abscess formation.

Paediatric nasopharyngeal carcinoma: an 8-year study from a tertiary care cancer centre in South India.

Nasopharyngeal carcinoma (NPC) accounts for less than 1 % of all paediatric cancers. Advances in imaging, radiation delivery, chemotherapy and improvement in multidisciplinary care have resulted in drastic changes in the outcome of this disease. Since NPC is extremely rare in paediatric population and there is paucity of data in Indian patients, we conducted the present study to analyze the outcome of paediatric NPC.

Laryngeal paraganglioma: a rare clinical entity managed by supraselective embolization and lateral pharygotomy.

Laryngeal paragangliomas are benign slow growing tumors with symptoms resembling squamous cell carcinoma. Hoarseness or dysphasia are the commonest presenting symptoms and usually it presents as an submucosal mass on laryngoscopy. Ninety percentage of these tumors occur in the supraglottic larynx and the rest in the glottis and the subglottic region.

Cutaneous malignancies in xeroderma pigmentosum: earlier management improves survival.

Xeroderma pigmentosum (XP) is a rare autosomal recessive disease, characterized by hypersensitivity of the skin to ultraviolet (UV) radiation leading to high incidence of skin cancer and progressive neurological complications. It results in premature development of neoplasias due to an exacerbated hypersensitivity to UV radiation causing premalignant and malignant lesions leading to death in early adulthood. Two cases of clinical features of xeroderma pigmentosa with skin lesions were managed in our department.

Paragangliomas of the carotid body: current management protocols and review of literature.

Paraganglioma is a rare neoplasm arising from carotid body usually benign and constitute 0.5 % of all total body tumors. They constitute 60-70 % of head and neck paraganglioma and resemble other paragangliomas of the body like glomus jugulare, glomus tympanicum, and pheochromocytoma.

Tonsillo-Styloidectomy for Eagle's Syndrome: A Review of 15 Cases in KVG Medical College Sullia.

Elongated styloid process causing Eagle's Syndrome is a rare clinical entity and the diagnosis is often difficult as a result of its vague symptomatology. However, palpation of tonsillar fossa with radiological demonstration of the elongated styloid process confirms the diagnosis. This is a report of a retrospective study conducted at the KVG Medical College, Hospital, Sullia, Karnataka, India where 15 patients who were surgically treated for Eagle's syndrome in the ENT department were retrospectively studied.

Genetic interactions between MTHFR (C677T), methionine synthase (A2756G, C2758G) variants with vitamin B12 and folic acid determine susceptibility to premature coronary artery disease in Indian population.

Background: Researchers have determined that Indians face a higher risk of heart disease, despite the fact that nearly half of them are vegetarians and lack many of the other traditional risk factors. In the below-30 age group, coronary artery disease mortality among Indians is three-fold higher than in the whites in United Kingdom and ten-fold higher than the Chinese in Singapore. High levels of homocysteine have been widely linked to the early onset of heart diseases in other populations, although a definite proof among Indians is lacking, which needs to be investigated by way of screening for factors responsible for high homocysteine levels.

Single-nucleotide polymorphisms in peroxisome proliferator-activated receptor gamma and their association with plasma levels of resistin and the metabolic syndrome in a South Indian population.

Studies on the association of the Pro12Ala and C1431T polymorphisms of PPAR? with diabetes and obesity have revealed extensive population-dependent variations. However, association of these polymorphisms with the metabolic syndrome and its individual components has not been well investigated in the Indian population. The Indian population harbours the maximum number of diabetics in the world who are thus more susceptible to metabolic disorders.

Premature coronary artery disease: role of free radical nitric oxide.

Aims/objectives: Over the last several decades, it has become amply evident that oxidative stress plays a significant role in the pathogenesis of coronary artery atherosclerosis and its complications. Relatively recent studies have demonstrated an association between increased oxidative stress and coronary artery disease. We therefore undertook this study to see the effect of free radical nitric oxide in patients with premature cardiovascular disease.
