RESUMO
Background: The objectives of this study were to find out of normal reference value for age?dependent longitudinal strain values in children and find its correlation with conventional echocardiographic parameters. Methods: In total, 100 healthy normal children aged between 2 and 15 years were enrolled and divided into three age groups, namely, 2–5 years, 5–10 years, and 10–15 years. Using the GE Vivid 7 ultrasound platform with 4 or 7 MHz probes, both LV and RV global longitudinal strains and conventional echocardiographic parameters were acquired. Results: In normal healthy children, left ventricular GLS values were –20.10 to –19.68 (mean: –19.89), –21.93 to –21.02 (mean: –21.48), and –20.87 to –20.41 (mean: –20.64)) in children aged 2–5 years, 5–10 years, and 10–15 years and right ventricular GLS values were –16.80 to –16.44 (mean: –16.62), –27.85 to –27.27 (mean: –27.56), –28.44 to –27.93 (mean: –28.19) in the above three groups, respectively. No significant increase was noted in the left ventricular strain value from basal to the apical segment from age group 2 years to 15 years and no gender differences were seen. None of the conventional echocardiographic parameters commonly used to assess the left or right ventricular systolic function had a significant correlation with LVGLS and RVGLS. Conclusions: The mean LVGLS values were –19.89, –21.48, and –20.64 and RVGLS were –16.62, –27.56, and –28.19 in healthy normal children aged 2–5 years, 5–10 years, and 10–15 years, respectively, and conventional echocardiographic parameters did not have any significant correlation with these values.
RESUMO
Background & objectives: In India, Kyasanur Forest Disease has been reported from the states of Karnataka, Kerala, Goa, and Maharashtra. The relationship between climatic factors and transmission of KFD remains untouched, therefore, the present study was undertaken. Methods: Based on the occurrence of cases, Shivamogga district (Karnataka) and Wayanad district in Kerala and northern Goa (Goa state) were selected for the study. Data on the incidence of KFD and climate factors were collected from concerned authorities. To determine the relationship between dependent and independent variables, spearman’s correlation was calculated for monthly as well as with lag months. Results: KFD cases and temperature (°C) were found significantly correlated up to 1 months’ lag period (p<0.05) while with precipitation relationship was found negatively significant for 0-3 months’ lag. The range of suitable temperature for KFD in Shivamogga, Goa and Wayanad was found as 20-31°C, 25-29°C and 27-31°C respectively. The cumulative precipitation during transmission months (November–May) ranged from <150-500mm, while in non-transmission months (June-October) from >1100-2400mm. Interpretation & conclusion: The analysis of three sites revealed that with the increase in temperature, the intensity of KFD transmission decreases as corroborated by the seasonal fluctuations in Shivamogga, Goa and Wayanad. High precipitation from June to October rovides suitable ecology to tick vector and sets in transmission season from November to May when cumulative precipitation is <500 mm.
RESUMO
Background: The development of pulmonary hypertension i.e.mean pulmonary artery pressure (mPAP) above 25 mmHg withnormal capillary wedge pressure and pulmonary vascularresistance(PVR) above 240 dyn/s/cm−5 in association withelevated pressure in portal circulation is known asportopulmonary hypertension (POPH). Comparing withidiopathic PAH, patients with POPH have a worst survivalprofile, with a 3-year survival of only 38% versus78% foridiopathic PAH. Recent evidence from France shows thatPOPH is the fourth most common form of PAH reported overallin the population-based French National Registry, afteridiopathic PAH and PAH associated with connective tissuediseases and con- genital heart disease. The aim of this studyis to evaluate frequency of POPH in portal hypertensivepatient.Materials and Methods: A cross sectional study of patientadmitted in RIMS, medicine department was performedfulfilling features of portal hypertension with ultrasoundshowing splenomegaly, ascites, portal vein diameter more than13 mm, portal vein velocity less than 15 cm/s and uppergastrointestinal endoscopy showing esophageal varices andpatient with connective tissue disease, congenital heartdisease, left ventricular systolic or diastolic dysfunction,valvular heart disease, lungs disease, sleep related breathingdisorder, chronic hemolytic and myeloproliferative disorderwere excluded. All patient underwent screening withechocardiography for measuring pulmonary artery systolicpressure (PASP) and PASP more than 35 mmHg wereconsidered for POPH which was confirmed with right heartcatheterisation by measuring mean pulmonary artery pressure(mPAP) of more than 25 mmHg.Observation: Among forty-two patient in this study, there werethirty-three male patients and nine female patients. POPH wasseen three female and two male patients with total of five out offorty- two with prevalence of 11.9% out of which 7.1% werefemale and 4.8% were male.Conclusion: Portopulmonary hypertension prevalence is 2–6%. In this study pulmonary hypertension is significantly high inportal hypertensive patient with percentage of 11.9% and moreprevalent in female.
RESUMO
Background: In coronary artery disease (CAD), the DELC (diagonal ear lobe crease) has been proposed as a marker but association remains controversial. The aim of the present study was to evaluate the frequency of DELC in patients with CAD. Materials and Methods: One hundred fifty four patients with coronary artery angiography proven CAD from RIMS, Ranchi, Jharkhand, India were evaluated for the presence or absence of DELC. The DELC was said to be present if the patient had crease extending diagonally from the tragus across the lobule to the rear edge of the without discontinuity. Observation: DELC was seen in 82 patients out of 154, and the prevalence was 53.24%. Prevalence of Hypertension, diabetes and dyslipidemia were 38.3% ,33.8% and 24.0% respectively and hypertension, diabetes and dyslipidemia were insignificant(P=0.245, P=0.526, P=0.203 respectively).There were 43 smoker (27.9%) and DELC with smoking was significant with p value(0.021). Conclusion: The frequency of DELC in patients with CAD was high in our study. The data suggest that the DELC sign may be a useful marker for the presence of CAD in patients and may help in early segregating at risk patient of CAD
