35 patients with chronic renal failure in the last phase receiving the periodical hemodialysis were examined by echocardiogram Doppler has shown that 100% of patients had left ventricular hypertrophy in which single hypertrophy (25.7%), hypertrophy combined with the left ventricular dilatation (34.3%) and left ventricular hypertrophy and dilatation and left ventricular systolic functional insufficiency (40%) the left ventricular diastolic function was significantly reduced. It was not found that there was close correlation between morphological change, cardiac hemodynamy and other factors

A prospective study on a group of 129 patient was echocardiographical compared with a group of 109 normal subjects: based on Framingham criteria, the prevalence of LV hypertrophy were 88.4%, LV dilatation - 58.9% and systolic dysfunction - 21.7%. To determine the influence of haemodyalysis on echo-Doppler indices of the heart, 58 patients were studied by Doppler-echocardiography immediately before and after haemodialysis. This procedure resulted in immediate alterations of the heart: decrease in blood pressure, increase in heart rate. Left ventricular diameters and volumes decreased significantly whereas, the systolic function, cardiac output and index increased. Haemodialysis elicited marked changes in the left ventricular filling pattern: mitral peak E, peak A, ratio E/A decreased and pulmonary vein flow S/D ratio increased. The results provide evidence for the pronounced preload-dependence of morphologic, functional and hemodinamic indices of the heart.

Study on 2 subject groups: control group including 48 healthy persons and case group: 34 patients (20 male, 14 female) with septic shock, all of them treated at Bach Mai Hospital from January 2003 to November 2003, aged from 16 to 75 year old. Subjects in control group underwent clinical and Doppler ultrasound examinations, had medical records. In case group, patients underwent clinical and paraclinical examinations for diagnosis and treatment followed by regime of the department. Results: 15/34 septic shock patients have cured and discharged (44.1%), 19 patients died (55.9%). At the first stage of septic shock, cardiac output (CO) and cardiac index (CI) increased (CO=6.461.85L/min; CI=4.351.24L/min/m2) but ejection fraction decreased (EF=50.69.27%), with 13 patients had EF<50% (38.2%). Before treatment, the CO and EF of survival group were lower than the dead group. During treatment, end-diastolic left ventricular volume increased along with EF, and heart rate reduced gradually to normal in survival group. These changes weren’t observed in the dead group.

51 patients with chronic renal failure of stage III (RF III group) were studied concerning clinical, biochemical, hematological with 109 healthy person (control group) and 117 patients with stage IV renal chronic failure (RF IV group). In RF III group, considerable changes were noted including dilation of left auricle and left ventricle, decrease of systolic function an disturbance of diastolic function, increase of pulmonary arterial pressure. In RT IV group, there are many differences in comparing with RT III group (more dilatation of left auricle and ventricle, less functioning of systole and higher level of diastole and of pulmonary arterial pressure. Therefore cardiac complications were more severe in RF IIIb versus RF IVa.

Background: Hypertension is one of the most common complications in chronic renal failure (CRF) patients. Dyslipidemia in primary hypertension has been considered a risk factor of cardiovascular diseases and progression of CRF. Objectives: To determine lipid disorders CRF patients with hypertension and the correlations between lipid disorders and blood pressure level in CRF patients. Subjects and method: The descriptive cross-sectional study involved 107 CRF patients under 45 years old, who had preservative treatments and were monitored at Bach Mai Hospital from 2000 to 2003. They were divided into 2 groups: hypertension (n=78; 72.9%) and nonhypertension (n=29, 27.1%). Results: In comparison with nonhypertension group, patients in the hypertension group had higher level of serum creatinine (877.7+/-597.1 vs. 587.6+/-381 micromol/L, p< 0.01), total cholesterol (5.35+/-1.34 vs. 4.81+/-1.23 mmol/L, p< 0.05), ApoB (1.07+/-0.34 vs. 1.00+/-0.32 g/L) and CT/HDL-C ratio (5.33+/-2.2 vs. 4.9+/-1.4). In the hypertension group, 25.6% patients had the total cholesterol >=6.2 mmol/L, significantly higher than those in the nonhypertension group (p< 0.05), and the prevalence of abnormal level of LDL-C and ApoB increased with the grade of CRF. Patients with grade III of hypertension had severe dyslipidemia: hypercholesterolemia, hyperglyceridemia, increased LDL-C and ApoB, and CT-HDL-C ratio >5. Among them, 92.1% had lipoprotein disorders. Conclusion: Increased total cholesterol accounted for 25.6% patients of hypertension group. Prevalence of patients with disorders of LDL-C and ApoB were high in hypertension group, and increased with the grade of CRF. Lipoprotein disorders were increased with the grade of hypertension.

Trombiculid “chigger” mites (Acari) are ectoparasites that feed blood on rodents and another animals. A crosssectional survey was conducted in 7 ecosystems of southern Vietnam from 2015 to 2016. Chigger mites were identified with morphological characteristics and assayed by polymerase chain reaction for detection of rickettsiaceae. Overall chigger infestation among rodents was 23.38%. The chigger index among infested rodents was 19.37 and a mean abundance of 4.61. A total of 2,770 chigger mites were identified belonging to 6 species, 3 genera, and 1 family, and pooled into 141 pools (10-20 chiggers per pool). Two pools (1.4%) of the chiggers were positive for Orientia tsutsugamushi. Ricketsia spp. was not detected in any pools of chiggers. Further studies are needed including a larger number and diverse hosts, and environmental factors to assess scrub typhus.
