  • It is generally acknowledged that congenital coronary artery fistula is an abnormal communication of the coronary artery with the right ventricle, right atrium,left atrium and left ventricle. In young people the symptoms are unusual , but significant symptoms and complications appear among the older age group such as congestive heart failure, subacute bacterial endocarditis, coronary steal syndrome, aneurysm formation, rupture, and pulmonary hypertension. Therefore, early surgical treatment is recommended. We experienced a case of coronary arteriovenous fistula that was involving the circumflex branch of the left coronary artery with the right ventricle. It was 10mm in diameter with multiple vegetation. We repaired the fistula under extracoporeal circulation. The patient was discharged in a healthy condition twelve days after operation .

  • A case of severe complications following intrathecal administration of 45 ml of hypertonic saline solution for the treatment of postherpetic neuralgia was presented. Transient immediate complications included were tachycardia, hypertension, neck stiffness and muscle twitch. Pulmonary edema, paralytic intestinal obstruction, and the cauda equina syndrome including sphincter disorder with atonic urinary bladder developed shortly after the injection. Tenesmus and sensory abnormality around perineum and soles were the longlasting complications.

  • Partial trisomy 3p results from either unbalanced translocation or $de$ $novo$ duplication. Common clinical features consist of dysmorphic facial features, congenital heart defects, psychomotor and mental retardation, abnormal muscle tone, and hypoplastic genitalia. In this paper, we report a case of partial trisomy 3p with rare clinical manifestations. A full-term, female newborn was transferred to our clinic. She had cleft lip-plate, dysgenesis of the corpus callosum, patent ductus arteriosus, pulmonary hypertension, and severe right-sided hydronephrosis, associated with ureteropelvic junction obstruction. Cytogenetic investigation revealed partial trisomy 3p; 46,XX,der(4)t(3;4)(p21.1;p16). The karyotype of her father showed a balanced translocation, t(3;4)(p21.1;p16). Therefore, the size of duplication can be an important factor.

  • The endothelial to mesenchymal transition (EndMT) is a newly recognized, fundamental biological process involved in development and tissue regeneration, as well as pathological processes such as the complications of diabetes, fibrosis and pulmonary arterial hypertension. The EndMT process is tightly controlled by diverse signaling networks, similar to the epithelial to mesenchymal transition. Accumulating evidence suggests that microRNAs (miRNAs) are key regulators of this network, with the capacity to target multiple messenger RNAs involved in the EndMT process as well as in the regulation of disease progression. Thus, it is highly important to understand the molecular basis of miRNA control of EndMT. This review highlights the current fund of knowledge regarding the known links between miRNAs and the EndMT process, with a focus on the mechanism that regulates associated signaling pathways and discusses the potential for the EndMT as a therapeutic target to treat many diseases.

  • Takayasu arteritis (TA) is a chronic inflammatory disease of unknown etiology that affects mainly the aorta, main aortic branches, and pulmonary arteries. Diverse neurological manifestations of TA have rarely been reported in children. Posterior reversible encephalopathy syndrome (PRES) is a neuroradiological condition that presents with headache, seizure, visual disturbances, and characteristic lesions on imaging. Inflammatory condition and severe hypertension in TA can cause PRES. We report of a 5-year-old girl with presumed TA who presented with PRES and chronic total occlusion in the renal artery. The findings on magnetic resonance imaging suggested PRES. Left nephrectomy was performed for total occlusion of the left renal artery, and the confirmatory diagnosis of TA was based on the pathologic findings of the renal artery.

  • A one-year-old, 3.25 kg intact male Chinchilla cat presented with acute right hind limb paralysis. Diagnostic imaging studies found cardiomegaly with interstitial lung pattern, abnormal mitral valve leaflets without maximum opening at the end of the ventricular diastole and during atrial systole and severe mitral inflow obstruction. Based on these findings and its young age, the case was diagnosed as congenital mitral valve stenosis. Treatment was directed to stabilize clinical conditions related to heart failure, to prevent further formation of thrombus and to relieve pain associated with thromboembolism. After one month of therapy, hind limb motor function was fully recovered.

  • Gaucher disease is a multisystemic disorder arising from a deficient activity of the lysosomal enzyme glucocerebrosidase, which leads to accumulation of glycosylceraide and other glycolipids in the regiculoendothelial system. The characteristics of Gaucher disease are anemia, thrombocytopenia, hepatosplenomegaly, and skeletal disease. Enzyme replacement therapy (ERT) has been proven to prevent progressive manifestations of Gaucher disease and effective in improving anemia, thrombocytopenia, bone markers and biomarkers. However, some patient needs still remain unmet because of the inaccessibility of certain sites including brain, bone and various organs. ERT could not Improve the irreversible lesion such as liver fibrosis, hepatopulmonary syndrome, and necrosis or infarction of bone and other organs. Adult patients with Gaucher disease should be screened for longterm complication such as bone disease, pulmonary hypertension, gallstone, and cancer, especially in patients with splenectomy. Parkinsonism and polyneuropathy was also reported among patients with type 1 Gaucher disease, but ERT does not improve neurological function. We need to review the benefits and unmet needs of ERT in Gaucher disease.

  • Takayasu`s arteritis is an arteritis of unknown etiology involving larger elastic arteries such as aorta and its branches, pulmonary arteries, and rarely coronary arteries. The late pathologic feature is vascular obstructive change and the resulting clinical manifestations are local ischemic symptoms such as syncope, visual disturbance, claudication of extremities, hypertension, and angina. the disease occurs predominantly in females, with the age of onset between 10 and 30 years. Recently we have experienced one case of Takayasu`s arteritis involving aortic arch and all its major branches. The patient was 36 year-old female and she was admitted because of headache, blurred vision, and easy fatigability and motor weakness of upper extremities. Aortogram revealed total obstruction of both carotid arteries at the site of its origin and partial irregular obstructive change in the innominate artery and both subclavian arteries. Bypass graft surgery using Gore-Tex grafts was performed with successful result.

  • Sleep-disordered breathing (SDB) is associated with increased cardiovascular and cerebrovascular morbidity. Epidemiological and clinic-based studies have shown that SDB is related to impaired glucose tolerance and increased insulin resistance, independent of obesity. Despite of a consistent association between SDB and impaired glucose-insulin metabolism, the mechanism underlying this relationship has not been fully elucidated. It is recognized that hypoxemia and hypercapnia that occur in SDB provoke sympathetic nervous activity and catecholamine, epinephrine and norepinephrine, and cortisol are released. Sympathetic hyperactivity and increased catecholamines can impair glucose homeostasis by increasing glycogenolysis and gluconeogenesis, which can result in increased circulating insulin levels and increased risk of insulin resistance. A prospective study is needed to investigate the causal relationship between SDB and impaired glucose-insulin metabolism in a healthy population without diabetes, hypertension and obesity as etiologic risk factors.

  • Congenital coronary arteriovenous fistula is a ~are condition, and with widespread use of cardiac catheterization, angiography and selective coronary arteriography is being recognized with increasing frequency. Surgical correction is strongly recommended to prevent the development of congestive heart failure,angina, subacute bacterial endocarditis, myocardial infarction, and pulmonary hypertension, as well as coronary aneurysm formation with subsequent rupture or embolization. I report a case of congenital coronary arteriovenous fistula of the left main coronary artery to the fight atrium in a 23 year old female, which is associated with bacterial endocarditis with right atrial vegetation.
