Total 193 patients over 16 years of age who have underwent a surgical correction of congenital heart diseases during the period 1964 to September of 1979 were reviewed. 106 patients were male and 87 patients were female. 85 patients were in the ages of 16 years through 20 years. The oldest patient was 54 years old male who had atrial septal defect. The commonest defects were atrial septal defect that accounted for 66 cases [34.2%]. Ventricular septal defect was next one that accounted for 66 cases [34.2%]. Patients with tetralogy of Fallot defects were 34 cases [17.6%]. 25 cases had patent ductus arteriosus [13.0%]. Patients with pulmonary stenosis were 17 cases [8.8%] and transposition of the great arteries cases were 2 cases [1%]. There were 14 cases of operative death in this series. So operative mortality rate was 7.3%. The commonest cause of death was low output syndrome and next was renal failure. This reviewed series reveals the incidence of operable congenital heart defects appearing in adult cardiac surgical patients and an aggressive surgical approach can be justified with low operative mortality like as pediatric age group.

The prevalence of childhood obesity is increasing worldwide at an alarming rate. While obesity is known to increase a variety of cardiovascular and metabolic diseases, it also acts as a risk factor for the development and progression of chronic kidney disease (CKD). During childhood and adolescence, severe obesity is associated with an increased prevalence and incidence of the early stages of kidney disease. Importantly, children born to obese mothers are also at increased risk of developing obesity and CKD later in life. The potential mechanisms underlying the association between obesity and CKD include hemodynamic factors, metabolic effects, and lipid nephrotoxicity. Weight reduction via increased physical activity, caloric restriction, treatment with angiotensin-converting enzyme inhibitors, and judicious bariatric surgery can be used to control obesity and obesity-related kidney disease. Preventive strategies to halt the obesity epidemic in the healthcare community are needed to reduce the widespread deleterious consequences of obesity including CKD development and progression.

Nephrotic syndrome (NS) is a common chronic glomerular disease in children characterized by significant proteinuria with resulting hypoalbuminemia, edema, and hyperlipidemia. Renal biopsy findings of diffuse foot processes effacement on electron microscopy and minimal change disease, focal segmental glomerulosclerosis (FSGS), or diffuse mesangial proliferation on light microscopy. It has been speculated that circulating permeability factors would be implicated in the pathogenesis of NS because they have been reportedly detected in the sera of patients and in experimental models of induced proteinuria. Moreover, a substantial portion of the patients with primary FSGS recurrence shortly after transplantation. This report reviews the current knowledge regarding the role of circulating permeability factors in the pathogenesis of proteinuria in NS and suggests future targeted therapeutic approaches for NS.

C3 glomerulopathy is a renal disorder involving dysregulation of alternative pathway complement activation. In most instances, a membranoproliferative pattern of glomerular injury with a prevalence of C3 deposition is observed by immunofluorescence microscopy. Dense deposit disease (DDD) and C3 glomerulonephritis (C3GN) are subclasses of C3 glomerulopathy that are distinguishable by electron microscopy. Highly electron-dense transformation of glomerular basement membrane is characteristic of DDD. C3GN should be differentiated from post-infectious glomerulonephritis and other immune complex-mediated glomerulonephritides showing C3 deposits.

The combination of central nervous system abnormalities and renal impairment is a notable characteristic of Galloway-Mowat syndrome (GAMOS), a disease which often accompanies microcephaly, developmental delay, and nephrotic syndrome. Many subtypes exist having various phenotypes and genotypes, and many genetic causes are still being identified. An 18-month-old boy first visited our clinic for seizure, delayed development, and microcephaly. During follow-up visits he developed proteinuria and nephrotic syndrome at the age of 6. Nephrotic syndrome became refractory to treatment. These phenotypes were suggestive of GAMOS. Next generation sequencing was performed for genetic analysis and revealed novel compound heterozygous variants in the WDR4 gene: c.494G>A (p.Arg165Gln) and c.540C>G (p.Ile180Met). This is the first case in Korea of GAMOS involving the WDR4 gene.

Type 2 diabetes mellitus (T2DM) leads to many health problems like diabetic nephropathy (DN). One of the key factors for chronic kidney disease and end-stage renal disease (ESRD) is T2DM. Extensive work is being done to delineate the pathogenesis of DN and to extend possible remedies. This review is intended to understand the nature of DN risk factors, progression, effects of glycemic levels, and stages of DN. We also explored the novel diagnostic and therapeutic approaches for DN such as gene therapy and stem cell treatments.

Dyslipidemia in nephrotic syndrome (NS) is often characterized by marked increases in the levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and other lipoproteins, such as very low-density lipoprotein, intermediate-density lipoprotein, and lipoprotein(a). It has been suggested that impaired catabolism of lipoproteins and cholesterol is mainly due to decreased lipoprotein lipase and hepatic lipase activity, and increased biosynthesis of lipoproteins in the liver. The management strategies for dyslipidemia in patients with NS consist of lifestyle modification, lipid-lowering agents represented by statins, second-line agents such as fibrates and bile acid sequestrants, and lipid apheresis. Compared with dyslipidemia in adult NS patients, whose risks of atherosclerotic disease and progressive renal injury are considered high, clinical data on dyslipidemia in pediatric NS patients are limited. Therefore, it is necessary to pay more attention to the evaluation and management of dyslipidemia in pediatric patients with NS in clinical practice.

The present communication attempts to evaluate the physicochemical and preliminary phytochemical studies on the fruit of Terminalia chebula Retz. Combretaceae family. Haritaki is one of the most celebrated herbs in the Indian traditional medicine system, Ayurveda. Terminalia chebula is known to exhibit different properties like anticancer, anti-inflammatory, anti-protozoal, antimicrobial, antioxidant, hepato and renal protective activities, and in the management of metabolic syndrome. As there is no detailed standardisation work reported on fruit, the physicochemical parameters, preliminary phytochemical constants, heavy metals, analysis are carried out. The phytochemical screening indicated the presence Tannin, Alkaloid, Phenol, Carbohydrate, Steroids, Protein and Resin compounds in CO₂ extract of Haritaki. The present investigation will helpful in assessing the quality and purity of a crude drug. Thus, the study provides facts that CO₂ extract of Haritaki contains medicinally important bioactive phytochemical compounds which justifies the use of plant species as conventional medicine for treatment of many diseases.

Gadolinium-based contrast agents (GBCAs) are commonly used for enhancement in MR imaging and have long been considered safe when administered at recommended doses. However, since the report that nephrogenic systemic fibrosis is linked to the use of GBCAs in subjects with severe renal diseases, accumulating evidence has suggested that GBCAs are not cleared entirely from our bodies; some GBCAs are deposited in our tissues, including the brain. GBCA deposition in the brain is mostly linked to the specific chelate structure of the GBCA: linear GBCAs were responsible for brain deposition in almost all reported studies. This review aimed to summarize the current knowledge about GBCA brain deposition and discuss its clinical implications.
