RESUMO

BACKGROUND: Although rare, the possibility of encountering an anomalous coronary artery is a reality. The outcome of such a procedure is greatly influenced by the awareness of the operator about the anatomical variations and the technique required. CASE PRESENTATION: A 50-year-old female patient presented with chest pain. On evaluation, she was found to have an inferior wall myocardial infarction. Left coronary angiography showed non-obstructive disease in the left anterior descending (LAD) and left circumflex artery (LCX). The right coronary artery could not be hooked despite multiple attempts and catheter changes. A non-specific aortic angiogram revealed anomalous origin of the right coronary artery (RCA) above the sinotubular junction on the left side. RCA was hooked with the AL-2 diagnostic catheter, and the percutaneous coronary intervention (PCI) procedure was completed via the same diagnostic catheter. CONCLUSION: In a life-threatening difficult situation like acute coronary syndrome with anomalous origin of coronary arteries, PCI can be done using a diagnostic catheter.

RESUMO

Reninoma, a renin-secreting tumor of the juxta-glomerular cells of the kidney, is a rare but surgically treatable cause of secondary hypertension in children. We report a case of reninoma presenting as cardiac syncope with long QTc on electrocardiogram due to hypokalemia.

RESUMO

Activation of mast cells in rheumatoid synovial tissue has often been associated with tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-8 production and disease pathogenesis by adjacent cell types. Butea monosperma (BM) is a well known medicinal plant in India and the tropics. The aim of this study was to examine whether a standardized extract of BM flower (BME) could inhibit inflammatory reactions in human mast cells (HMC) using activated HMC-1 cells as a model. Four previously characterized polyphenols--butrin, isobutrin, isocoreopsin, and butein--were isolated from BME by preparative thin layer chromatography, and their purity and molecular weights were determined by liquid chromatography/mass spectrometry analysis. Our results showed that butrin, isobutrin, and butein significantly reduced the phorbol 12-myristate 13-acetate and calcium ionophore A23187-induced inflammatory gene expression and production of TNF-alpha, IL-6, and IL-8 in HMC-1 cells by inhibiting the activation of NF-kappaB. In addition, isobutrin was most potent in suppressing the NF-kappaB p65 activation by inhibiting IkappaBalpha degradation, whereas butrin and butein were relatively less effective. In vitro kinase activity assay revealed that isobutrin was a potent inhibitor of IkappaB kinase complex activity. This is the first report identifying the molecular basis of the reported anti-inflammatory effects of BME and its constituents butrin, isobutrin, and butein. The novel pharmacological actions of these polyphenolic compounds indicate potential therapeutic value for the treatment of inflammatory and other diseases in which activated mast cells play a role.

RESUMO

Eccrine Porocarcinoma (ECP) is a malignant tumour arising from the intraepithelial ductal parts of the sweat gland. It has also been described as malignant hidroacanthoma simplex, sweat gland carcinoma, malignant intra-epidermal eccrine poroma, eccrine poroepithelioma, dysplastic poroma, malignant syringo acanthoma and porocarcinoma. Treatment with wide local excision but metastatic lesions can be treated with chemotherapy. Here, we present a case report of 52 years old male who presented with a fungating growth on left pre-auricular region that came out to be a case of ECP on histopathological examination.

RESUMO

Several recent studies have documented that supplementation with pomegranate fruit extract inhibits inflammatory symptoms in vivo. However, the molecular basis of the observed effects has not been fully revealed. Although previous studies have documented the inhibition of nitric oxide and cyclooxygenase (COX) activity in vitro by plant and fruit extracts added directly into the culture medium but whether concentrations of bioactive compounds sufficient enough to exert such inhibitory effects in vivo can be achieved through oral consumption has not been reported. In the present study we determined the effect of rabbit plasma obtained after ingestion of a polyphenol rich extract of pomegranate fruit (PFE) on COX enzyme activity ex vivo and the IL-1beta-induced production of NO and PGE2 in chondrocytes in vitro. Plasma samples collected before and 2 hr after supplementation with PFE were tested. Plasma samples collected after oral ingestion of PFE were found to inhibit the IL-1beta-induced PGE2 and NO production in chondrocytes. These same plasma samples also inhibited both COX-1 and COX-2 enzyme activity ex vivo but the effect was more pronounced on the enzyme activity of COX-2 enzyme. Taken together these results provide additional evidence of the bioavailability and bioactivity of compounds present in pomegranate fruit after oral ingestion. Furthermore, these studies suggest that PFE-derived bioavailable compounds may exert an anti-inflammatory effect by inhibiting the inflammatory cytokine-induced production of PGE2 and NO in vivo.

RESUMO

OBJECTIVE: Although consumption of dietary supplements containing pomegranate extract (POMx) by patients with arthritis is on the rise, the efficacy of such preparations in suppressing joint inflammation and damage is not known. The present study was designed to evaluate a standardized preparation of POMx using collagen-induced arthritis (CIA) in mice, a widely used animal model of rheumatoid arthritis. METHODS: CIA-susceptible DBA/1 mice were fed POMx by gavage before and after immunization with chicken type II collagen. Severity of clinical arthritis was scored using a visual scoring system. Arthritic joints were analyzed by histopathology and graded. Lysates were generated from mouse joints and levels of anti-type II collagen immunoglobulin G and inflammatory cytokines interleukin (IL)-1beta, IL-6, and tumor necrosis factor-alpha were quantified by enzyme-linked immunosorbent assay. The effect of POMx on lipopolysaccharide-induced nitric oxide production was determined by Griess reaction and mitogen-activated protein kinase activation was studied by western immunoblotting in mouse macrophages. RESULTS: Consumption of POMx potently delayed the onset and reduced the incidence of CIA in mice. Severity of arthritis was also significantly lower in POMx-fed animals. Histopathology of the arthritic joints from POMx-fed mice demonstrated reduced joint infiltration by the inflammatory cells, and the destruction of bone and cartilage were alleviated. Levels of IL-6 were significantly decreased in the joints of POMx-fed mice with CIA. In mouse macrophages, POMx abrogated multiple signal transduction pathways and downstream mediators implicated in the pathogenesis of rheumatoid arthritis. CONCLUSION: Our studies suggest that inhibition of a spectrum of signal transduction pathways and the downstream pathogenic cellular response by POMx or compounds derived from it may be a useful approach for the prevention of the onset and severity of inflammatory arthritis.
