Background Aortic dilatation is associated with the presence of aortic diseases. Current guidelines for assessing the aortic root (AoR) depend on linear measurements acquired by two-dimensional (2D) echocardiography. We considered that real-time three-dimensional echocardiography, which correlates better with AoR volume obtained by computed tomography, is widely unavailable, and therefore, there is a need to determine the AoR volume using 2D echocardiography. Methods Fifty-one consecutive apparently healthy volunteers were recruited and subsequently divided into three age groups. Specified planes of acquisition and previously defined landmarks were identified, and phases of the cardiac cycle that allowed for measurement standardization were used. Volume was determined by the modified Simpson's method. Results Although the average diastolic and systolic volume measurements of the AoR dimensions were not significantly different across the three age groups in the study population, a highly significant difference was observed in the volume measurements between male and female normotensive persons, P < 0.01 in each case. AoR volume measurements were five times in the diseased compared with the normotensive individuals; however, linear measurements were only 1.5 times in size of the normal individuals. Both point and interval estimates of the volume measurements of AoR in adult normotensives in three age groups were presented as baseline information. Conclusions We hereby present a novel way to determine the AoR volume using 2D echocardiography and the normal reference range with respect to age and gender. We also established the relevance of our measurement by comparing the normal population with two isolated diseased aortas.

F.VIII R:Ag was determined by quantitative immunelectrophoresis (I.E.) with a prefabricated system. The prefabricated system consists of a monospecific f.VIII rabbit antiserum in agarose on a plastic plate for the one and two dimensional immunelectrophoresis. The lognormal distribution of the f.VIII R:Ag concentration in the normal population was confirmed (for n=70 the f.VIII R:Ag in % of normal is = 95.4 ± 31.9). Among the normal population there was no significant difference between blood donors (one blood donation in 8 weeks; for n=43 the f.VIII R:Ag in % of normal is = 95.9 ± 34.0) and non blood donors (n=27;f.VIII R:Ag = 94.6 ± 28.4 %). The f.VIII R:Ag concentration in acute hepatitis B ranged from normal to raised values (for n=10, a factor of 1.8 times of normal was found) and was normal again after health recovery (n=10, the factor was 1.0). in chronic hepatitis the f.VIII R:Ag concentration was raised in the majority of the cases (for n=10, the factor was 3.8). Out of 22 carrier sera 20 showed reduced, 2 elevated levels of the f.VIII R:Ag concentration. in 5 sera no f.VIII R:Ag could be demonstrated. The f.VIII R:Ag concentration was normal for n=10, reduced for n=20 and elevated for n=6 in non A-non B hepatitis (n=36). Contrary to results found in the literature no difference in the electrophoretic mobility of the f.VIII R:Ag was found between hepatitis patients sera and normal sera.

Objective: This study was conducted to quantify the normal indices of anthropometric measures related to ophthalmology including Interpupillary distance (IPD), Inner canthal distance (ICD), Outer canthal distance (OCD) in a normal, healthy Pakistani population. Methods: This is a cross sectional study. Total 500 patients were chosen randomly but 499 were included in this study. Patients were selected randomly in an outpatient department of Jinnah Post Graduate Medical Centre Karachi, over the period of five months. IPD, ICD & OCD all measurements were taken with the help of plastic rule by only one researcher to minimize chances of error as much as possible. IPD was reconfirmed from auto refractometer while ICD and OCD readings were taken twice by occluding one eye of researcher to reduce error. Participants were divided into four categories on basis of: Age, Gender, ethnicity and geographical location. Patients were further categorized on basis of Ethnicity to Urdu Speaking, Sindhi, Punjabi, Pathan, and others. Moreover, four age groups were drawn ranging from 15-24 years, 25-44 years, 45-64 years and 65 years and greater. Results: Our study comprised a total of 499 patents of which 272(54.5%) were males, and 227(45.5%) were females. The mean age of the participants was 39.3 ± 14.5 years. The mean values for the IPD, ICD and OCD in mm were 61.8 ± 6.2, 30.9 ± 2.9 and 85.2 ± 6.6 respectively. A statistically significant difference was observed between IPD, ICD and OCD Indices among male and female study participants (p<0.001, p=0.043, p<0.001). While comparing the IPD, ICD and OCD indices amongst the different ethnic groups, we found no statistically significant difference (p=0.09. p=0.28, p=0.06). Overall, there was no correlation between the age and other variables i.e. IPD, ICD, OCD, (r = 0.07, p = 0.085), (r = 0.005, p = 0.906), (r = -0.08, p = 0.058). Conclusion: This work has recommended normative values of IPD, ICD and OCD in Pakistani population on the basis different variables including gender, age, and ethnicity.

AbstractThis retrospective cohort study investigated the association between in-hospital survival and two-dimensional (2D) echocardiography within 24 hours after the return of spontaneous circulation (ROSC) in patients who underwent in-hospital cardiopulmonary resuscitation (ICPR) after in-hospital cardiopulmonary arrest (IHCA). The 2D-echo and non-2D-echo groups comprised eligible patients who underwent transthoracic 2D echocardiography performed by the cardiology team within 24 hours after ROSC and those who did not, respectively. After propensity score (PS) matching, 142 and 284 patients in the 2D-echo and non-2D-echo groups, respectively, were included. A logistic regression analysis showed that the likelihood of in-hospital survival was 2.35-fold higher in the 2D-echo group than in the non-2D-echo group (P < 0.001). Regarding IHCA aetiology, in-hospital survival after cardiac arrest of a cardiac cause was 2.51-fold more likely in the 2D-echo group than in the non-2D-echo group (P < 0.001), with no significant inter-group difference in survival after cardiac arrest of a non-cardiac cause (P = 0.120). In this study, 2D echocardiography performed within 24 hours after ROSC was associated with better in-hospital survival outcomes for patients who underwent ICPR for IHCA with a cardiac aetiology. Thus, 2D echocardiography may be performed within 24 hours after ROSC in patients experiencing IHCA to enable better treatment.

Static And Dynamic Tests

It was the purpose of this study to investigate differences between visual perception of static (non-moving) and dynamic (moving) two-dimensional objects at several ages. This study specifically assessed the ability of four age groups to perceive figure-ground: Elementary 1 (age 6 to 7 yr.); Elementary 6 (age 11 to 13 yr.); College (age 18 to 22 yr.); Elderly Adult (age 66 to 79 yr.). A total of 169 Ss were tested. A test of visual perception of figure-ground was selected and adapted to a dynamic condition. Results showed there was a significant difference between performance on the static and dynamic tests of visual perception across all age levels, with fewer errors made on the dynamic test. There was a significant difference in performance between ages. It was concluded that there is a difference between static and dynamic visual perception of figure-ground at the ages studied and that perception of figure-ground tends to improve with age.
