Heart failure following cavopulmonary shunt - An unusual story of desmin cardiomyopathy.

Partial cavopulmonary shunt is an established procedure for patients with abnormal right ventricular (RV) physiology. Late failure of the Glenn shunt is usually due to further progression of the primary disease process. However, there may be surprises, as in our patient.

Large left ventricular outflow tract mass in a young patient: uncommon presentation of a common disease! A case report.

Background: Infective endocarditis (IE) predominantly involves the cardiac valves. Timely diagnosis and initiation of therapy significantly reduce morbidity and mortality. Infective endocarditis presenting as a large left ventricular outflow tract (LVOT) mass is an atypical manifestation that provides significant challenges to the treating team.

Genetics of 67 patients of suspected primary ciliary dyskinesia from India.

Data are limited on the genetic profile of primary ciliary dyskinesia (PCD) from developing countries. Here, we report one of the first study on genetic profile of patients with suspected PCD from India. In this prospective cross-sectional study, we enrolled 162 children with suspected PCD.

Relevance of Partial p16 Immunostaining in Oral Squamous Cell Carcinoma and Co- Relation with HPV DNA Status.

Introduction: Immunostaining criteria for p16 positivity in oropharyngeal squamous cell carcinoma have been laid down by College of American Pathologists (CAP) and the American Society of Clinical Oncology (ASCO). The staining should be of moderate to strong intensity seen in 70 percent of the tumor cells. Recent studies have pointed out that a small minority of cases are missed using p16 as the surrogate marker at above mentioned cut off.

Effect of vinpocetine alone and in combination with enalapril in experimental model of diabetic cardiomyopathy in rats: possible involvement of PDE-1/TGF-β/ Smad 2/3 signalling pathways.

Objective: Diabetic cardiomyopathy (DC) is one of the severe secondary complications of diabetes mellitus in humans. Vinpocetine is an alkaloid having pleiotropic pharmacological effects. The present study is designed to investigate the effect of vinpocetine in DC in rats.

Diphtheritic myocarditis: An unusual and reversible cause of heart failure.

Diphtheria is a life-threatening infectious disease caused by . Although the disease is seen infrequently in the postvaccination era, sporadic cases continue to occur. Cardiac involvement, in the form of myocarditis, is the most serious manifestation of diphtheria and is the most common cause of mortality in these patients.

Differential effect of basal vitamin D status in monocrotaline induced pulmonary arterial hypertension in normal and vitamin D deficient rats: Possible involvement of eNOS/TGF-β/α-SMA signaling pathways.

Vitamin D deficiency is common and linked to poor prognosis in pulmonary arterial hypertension (PAH). We investigated the differential effect of basal vitamin D levels in monocrotaline (MCT) induced PAH in normal and vitamin D deficient (VDD) rats. Rats were fed a VDD diet and exposed to filtered fluorescent light to deplete vitamin D.

Pregestational diabetes alters cardiac structure and function of neonatal rats through developmental plasticity.

Pregestational diabetes (PGDM) leads to developmental impairment, especially cardiac dysfunction, in their offspring. The hyperglycemic microenvironment inside the uterus alters the cardiac plasticity characterized by electrical and structural remodeling of the heart. The altered expression of several transcription factors due to hyperglycemia during fetal development might be responsible for molecular defects and phenotypic changes in the heart.

Evaluation of clinical efficacy and laboratory indicators of non-cultured epidermal cell suspension and hair follicle cell suspension in surgical management of stable vitiligo: A randomized comparative trial.

Background: Non-cultured epidermal cell suspension (ECS) and hair follicle cell suspension (HFCS) are well-established methods of surgical treatment of stable vitiligo.

Aims: The aim of the present study was to compare the laboratory indicators and clinical efficacy of ECS and HFCS in the treatment of stable vitiligo.

Methods: This was a single centre, open-labeled randomized trial.

Ventricular Tachycardia: A Rare Case of Myocardial Silicosis.

Chronic exposure to silica is a recognized health hazard. Manifestations of pulmonary and extrapulmonary silicosis are well described. Secondary pulmonary arterial hypertension and pericardial involvement are described, but myocardial involvement has not been reported.

Clinico-pathological features in fatal COVID-19 infection: a preliminary experience of a tertiary care center in North India using postmortem minimally invasive tissue sampling.

Objectives: To study the histopathology of patients dying of COVID-19 using post-mortem minimally invasive sampling techniques.

Methods: This was a single-center observational study conducted at JPNATC, AIIMS. Thirty-seven patients who died of COVID-19 were enrolled.

Allyl Methyl Sulfide Preserved Pressure Overload-Induced Heart Failure Via Modulation of Mitochondrial Function.

Background: Cardiovascular diseases are the leading cause of death globally, and they are causing enormous socio-economic burden to the developed and developing countries. Allyl Methyl Sulfide (AMS) is a novel cardioprotective metabolite identified in the serum of rats after raw garlic administration. The present study explored the cardioprotective effect of AMS on thoracic aortic constriction (TAC)-induced cardiac hypertrophy and heart failure model in rats.

Sirt1 and Sirt3 Activation Improved Cardiac Function of Diabetic Rats via Modulation of Mitochondrial Function.

In the present study, we aimed to evaluate the effect of Sirt1, Sirt3 and combined activation in high fructose diet-induced insulin resistance rat heart and assessed the cardiac function focusing on mitochondrial health and function. We administered the Sirt1 activator; SRT1720 (5 mg/kg, i.p.

Primary intimal sarcoma of the pulmonary artery misdiagnosed as pulmonary thromboembolism: A case confirmed at medicolegal autopsy.

Misdiagnosed PAS confirmed at medicolegal autopsy Pulmonary artery sarcoma (PAS) is a rare disease and usually indistinguishable from acute or chronic thromboembolic disease of the pulmonary arteries. We present a case of pulmonary artery sarcoma in a 54-year-old male, who was clinically misdiagnosed as pulmonary thromboembolism. The patient died of disease; however, the actual diagnosis of PAS was made after a medicolegal autopsy.

Allylmethylsulfide, a Sulfur Compound Derived from Garlic, Attenuates Isoproterenol-Induced Cardiac Hypertrophy in Rats.

Allylmethylsulfide (AMS) is a novel sulfur metabolite found in the garlic-fed serum of humans and animals. In the present study, we have observed that AMS is safe on chronic administration and has a potential antihypertrophic effect. Chronic administration of AMS for 30 days did not cause any significant differences in the body weight, electrocardiogram, food intake, serum biochemical parameters, and histopathology of vital organs.

Biochemical findings in sudden unexpected death in epilepsy: Hospital based case-control study.

Purpose: A review study on the biochemistry of epilepsy showed that in epileptic patients, serum glucose and cholesterol concentrations are low, sodium is unaffected, potassium increases, glucose is high and mild hypocalcemia. We have conducted a biochemical study on sudden unexpected death in epilepsy (SUDEP) cases in an attempt to establish the characteristic biochemical values to diagnose these deaths.

Methods: This was a hospital based case-control study done at All India Institute of Medical Sciences, New Delhi for one year.
