External auditory canal injuries in maxillofacial trauma - Proposal of a symptom-based treatment algorithm with a report of twelve cases.

Purpose: Injury to the external auditory canal (EAC) may occur following facial trauma. They manifest as otalgia, ear bleeding, otorrhea, facial palsy, or altered hearing. But literature regarding its management is sparse.

Clinical relevance of double-arm blood pressure measurement and prevalence of clinically important inter-arm blood pressure differences in Indian Primary Care.

Hypertension guidelines recommend measuring blood pressure (BP) in both arms at least once. However, this is seldom done due to uncertainties regarding measurement procedure and the implications of finding a clinically important inter-arm BP difference (IAD). This study aimed to provide insight into the prevalence of clinically important IADs in a large Indian primary care cohort.

Cardiological society of India document on safety measure during echo evaluation of cardiovascular disease in the time of COVID-19.

An echocardiographic investigation is one of the key modalities of diagnosis in cardiology. There has been a rising presence of cardiological comorbidities in patients positive for COVID-19. Hence, it is becoming extremely essential to look into the correct safety precautions, healthcare professionals must take while conducting an echo investigation.

Quantitative assessment of left ventricular systolic function using 3-dimensional echocardiography.

Assessment of left ventricular systolic function is the commonest and one of the most important indications for performance of echocardiography. It is important for prognostication, determination of treatment plan, for decisions related to expensive device therapies and for assessing response to treatment. The current methods based on two-dimensional echocardiography are not reliable, have high degree of inter-observer and intra-observer variability and are based on presumptions about the geometry of left ventricle (LV).

Patterns and predictors of prehypertension among "healthy'' urban adults in India.

Cardiovascular disease is still on the increase in India owing to changing socioeconomic factors and unhealthy lifestyles. Better understanding of the role of hypertension (HTN) has led to new Joint National Committee (JNC-7) guidelines for its diagnosis and management. The authors aimed to evaluate the predictors and correlates of prehypertension (PreHTN) among adults in urban India.

Safety and efficacy of enalapril in multivalvular heart disease with significant mitral stenosis--SCOPE-MS.

Angiotensin-converting enzyme inhibitors (ACEI) are often used in preventing and treating heart failure due to regurgitant valve disease. The majority of patients with symptomatic rheumatic heart disease (RHD) have significant mitral stenosis (MS) and are denied ACEI therapy, because of the fear of hypotension in the presence of fixed obstruction. The authors assessed the safety and efficacy of ACEI in 109 consecutive patients with RHD and with significant mitral stenosis (mitral valve orifice, MVO < 1.

Efficacy and optimal dose of sildenafil in primary pulmonary hypertension.

Purpose: We aimed to assess the effects of sildenafil and evaluate optimal dosing in primary pulmonary hypertension (PPH). Sildenafil selectively inhibits phosphodiesterase 5 (PDE5), which is abundant in pulmonary and penile tissue. This results in increasing nitric oxide (NO) at tissue level leading to pulmonary vasodilatation.

Role of transthoracic Doppler pulmonary venous flow pattern in large atrial septal defects.

Objective: Large uncomplicated atrial septal defect (ASD) alters the pulmonary venous flow (PVF) pattern. We aimed to study the role of transthoracic echocardiography (TTE) in estimating the PVF Doppler abnormalities in ASD. By repeating the study soon after ASD closure, we correlated the hemodynamics of atrial shunting with PVF patterns.

Right atrial aneurysm in adults--report of three cases and review of literature.

Right atrial aneurysm (RAA) or RA diverticula are described as saccular structures originating from the RA free wall. This must be differentiated from aneurysmal dilation of the entire right atrium. We diagnosed three cases of RAA since 2000.

Myocardial performance index in evaluation of acute right ventricular myocardial infarction.

The goal of this study was to evaluate the role of Doppler time interval-derived myocardial performance index (MPI) in the setting of acute right ventricular myocardial infarction (RVMI). Inferior myocardial infarction is accompanied by RVMI in over a third of cases. We do not have easily applicable noninvasive tools for reliably quantifying the right ventricular (RV) dysfunction in RVMI and to serially follow alterations.

Congenital submitral aneurysm and sinus of valsalva aneurysm.

Submitral aneurysm (SMA) is congenital outpouching of the left ventricular (LV) wall invariably occurring adjacent to the posterior leaflet of mitral valve. SMA is typically diagnosed in young adults who present with severe mitral regurgitation, heart failure, systemic embolism, and sudden cardiac death. African blacks account for the majority of the reported SMA cases.

Safety and efficacy of angiotensin-converting enzyme inhibitors in symptomatic severe aortic stenosis: Symptomatic Cardiac Obstruction-Pilot Study of Enalapril in Aortic Stenosis (SCOPE-AS).

Background: Animal models have demonstrated a benefit of angiotensin-converting enzyme inhibitors (ACEI) in experimental aortic stenosis (AS), and intravenous nitroprusside has shown hemodynamic improvements in AS with left ventricular (LV) dysfunction. Although routinely used in most heart failure situations, ACEI are avoided in AS because of the risk of hypotension. We aimed to determine the clinical tolerance and efficacy of the ACEI enalapril in the setting of symptomatic severe AS.

Massive left atrial appendage aneurysm presenting as supraventricular tachycardia.

Left atrial appendage aneurysm is a rarely reported condition. Symptoms are absent in childhood and diagnosis is usually incidental. Systemic embolization or arrhythmia can bring these cases to medical attention.

Percutaneous transluminal mitral commissurotomy--experience with inoue balloon and over the wire technique.

Objective: To compare the immediate and long-term results, safety and complication profile of inoue balloon technique (IBT) and over the wire technique (OWT) in the treatment of rheumatic mitral stenosis.

Methods: We have compared the IBT in 104 patients and OWT in 40 patients. Preprocedural, immediate post-procedure and follow-up echocardiograms of both groups of patients were done.

Isolated congenital left ventricular diverticulum in adults.

Isolated congenital ventricular diverticulum or aneurysm is rare and usually arises from the left ventricle. The presentation of this condition is diverse. We report three cases of isolated congenital left ventricular diverticula.

Valvuloplasty balloon detaching from the stem of a catheter.

A 12-year-old boy underwent pulmonary balloon valvotomy for isolated critical pulmonary stenosis. Following valvotomy, blood was found to be drawn into the syringe during deflation of the balloon, so a provisional diagnosis of a burst balloon was made. However, when the balloon catheter was withdrawn, the balloon got detached from the stem of the catheter at the level of the right atrium and was retained over the exchange guidewire.

Propofol versus midazolam for monitored sedation: a comparison of intraoperative and recovery parameters.

Study Objective: To compare intraoperative and recovery parameters in patients who received either propofol infusion (PI), propofol bolus (PB), or midazolam bolus (MZ) for sedation.

Design: Randomized clinical study.

Setting: Medical/surgical patients in a specialized hospital.

Postthoracotomy respiratory muscle mechanics during incentive spirometry using respiratory inductance plethysmography.

We undertook this study to characterize the postthoracotomy compartmental displacement and respiratory mechanical changes occurring during and after the performance of the incentive spirometry maneuver. We also evaluated the effect of recumbency angle on compartmental recruitment. Sixteen patients were randomized to perform incentive spirometry either at 30 degrees or 60 degrees recumbency angle.

Effect of midazolam on the auditory event-related potential: measures of selective attention.

To elucidate the delayed effects of midazolam, we assessed electrophysiologic and motor responses by measuring auditory event-related potentials and a button-press reaction time response in 10 normal volunteers (aged 25-36 yr). Fifty minutes after intravenous infusion of 0.07 mg/kg of midazolam, subjects were mildly sedated, oriented, and readily responsive to verbal commands.
