BACKGROUND The transient left ventricular apical ballooning syndrome, also known as takotsubo cardiomyopathy was first described in Japan approximately 20 years ago (Satoh and coworkers, 1991). It was later described elsewhere as well and is being increasingly recognized. Takotsubo Cardiomyopathy characterized by transient apical and midventricular LV dysfunction in the absence of significant coronary artery disease that is triggered by emotional or physical stress. Its name refers to a contraption used for catching octopuses and suggests the aspect assumed by the ventricle during the systole due to the typical regional wall motion abnormalities that occur after onset. Takotsubo cardiomiopathy occurring mainly in post-menopausal women, echocardiography in the Takotsubo cardiomyopathy reveals during its acute phase a ballooning resembling the octopus trap configuration--the apex and lateral ventricular segments are hypokinetic while the base is hyperkinetic--along with reduced ejection fraction. Ventricular function will usually recover within a few days/weeks. OBJECTIVE AND PURPOSE The objective of this study is to determine the role of echocardiography in detecting and establishing the diagnosis of Takotsubo cardiomiopathy in patients with suspect acute coronary syndrome and during the follow up period. PATIENTS AND METHODS The study covered 12 adult patients the majority are women (92%) who were subjected to echocardiography evaluation as part of the clinical cardiological examination due to suspect acute coronary syndrome or Takotsubo Stress Cardiomyopathy. The patients were examined on an ultrasound machine Philips iE 33 x Matrix, ATL HDI and GE Vived 7 equipped with all cardiologic probes for adults and multi-plan TEE probes. We evaluated clinical characteristics, LV systolic function, biomarkers, and prognosis in all patients. RESULTS Among all the patients referred for Echocardiographic evaluation for left ventricle motion abnormalities with suspect acute coronary syndrome, the echo exam revealed 12 patients with acute apical ballooning which involving the left ventricular apex and med-ventricle. The triggering factors were physical stress in 4 patients (33%) and emotional stress in 8 patients (67%). The initial symptom was chest pain (n = 8, 67%) rather than dyspnea (n = 4, 33%). An initial electrocardiogram (EKG) presented ST-elevation (n = 10, 83%) and T-wave inversion (n = 2, 17%), other data are shown on Table 2. Among the all patients 8 of them (66%) had normal EF by the 1st follow up (47 +/- 51 days), and the rest 4 patients (34%) had normal EF by 68 +/- 96 days. CONCLUSION Widespread uses of echocardiography has contributed to more frequent recognition of Takotsubo stress cardiomyopathy and highlight the central role of this noninvasive method from an echocardiographers' perspective.

The open prospective combined cytogenetic and clinical study investigated the impact of biological therapy Rituximab on number and structure of chromosomes in Rheumatoid arthritis patients. The purpose of this study was to investigate safety of Rituximab on chromosomes as well as cytotoxic therapy Methotrexate. A total of 8 seropositive Rheumatoid arthritis patients were analyzed for primary end point of eventual cytotoxic effect of Rituximab. Assessment was done before and 1 month later, actually 2 weeks after the administration of full course of Rituximab in infusion. Patients suffering from active Rheumatoid arthritis were randomly assigned according to established protocol to receive infusion of Rituximab in a full dose of 2.0 grams divided in a two doses of 1.0 gram on days 1 and 15. The lymphocytes from peripheral blood were cultured according to Moorhead method. The results obtained from this investigation showed that normal male and female karyogram was found after the full therapy of Rituximab. The results from this study, that was done on a rather small number of subjects, indicate that Rituximab does not express either clastogenic or aneugenic effects. But, co-finding of this study was that Methotrexate had a side effect on chromosomal aberration in one female RA patient, and after discontinuation of this treatment the normal karyogram was observed.
