ABSTRACT
Background: Dermatoglyphics, the ridged skin covering our palms and sole, are not only found on human beings. All primates have ridged skin, and it can also be found on the paws of certain mammals and on the tails of some monkey species. Palmar creases develop during the 2nd and 3rd month of intrauterine life and are not influenced by movement of hand in utero. They are of considerable clinical interest because they are affected by certain abnormalities of early development including genetic disorders. Aim: The present study is carried out to correlate the dermatoglyphic patterns in patients of bronchial asthma. Methods: Dermatoglyphic prints were obtained from both hands of 100 patients of bronchial asthma among Afro-Trinidadian and Indo-Trinidadian. Hundred normal healthy individuals, without family history of bronchial asthma, were selected as control group. The qualitative parameters like whorls, loops and arches were studied in the above mentioned study groups. Results: Presence of whorls loops and arches showed significant difference, p<0.01in III and IV digits in Afro-Trinidadian group and only in III digit in Indo-Trinidadian group when compared to the controls. The intergroup comparisons also showed significant changes in the percentage of all the finger print patterns in the II & III digit in Afro-Trinidadian bronchial asthma patient when compared with Indo-Trinidadian bronchial asthma patients. Conclusion: Presence of whorls, loops and arches on both the III digit can be used as one of the diagnostic criterion for patients with bronchial asthma.
ABSTRACT
Benign prostatic hyperplasia (BPH) is the non-malignant enlargement of the prostate. Estimation of Prostate volume and dimensions contribute significantly to the management of BPH. Correlations between the trans-abdominal and trans-rectal ultrasound methods in estimating prostate volume and dimensions were studied with variable results. Ninety-one consecutive patients of 50 years or older with were scanned by Trans abdominal and transrectal sonographs (TA&TRUS) at the same session after obtaining the consent. All the scans were performed on a single ultrasound machine. The volume and dimensions of the prostate obtained by both methods were compared and correlated using Pearson correlation coefficient. The data was analysed further in groups based on volumes and ethnicity. Twenty-four patients were also scanned by other consultant radiologist and the data was analysed to compare the interobserver variations. Results: The mean age of the patients was 66.03±10.41 years. The mean prostate volume for ninety one patients by TA & TRUS was 44.4±35.1 ml and 46.2±34.7 ml, respectively (r = 0.965, p<0.001). Among the total patients 42 were of East Indian (EI) origin, 45 were of Caribbean African (CA) origin and 4 were of mixed race. The mean prostate volume of EI race by TA & TRUS was 35.3±23.3 and 38.9±25.9 ml respectively(r = 0.950, p<0.001). The mean prostate volume of CA race by TA & TRUS was 50.8±39.4 and 51.0±38.5 ml, respectively (r = 0.967, p<0.001). The mean prostate volume of observer A and observer B by TA & TRUS was 43.5±28.8 and 45.8±25.9 ml (r = 0.953, P<0.001) and 46.6±39 and 46.9±27.4 ml (r = 0.877, p<0.001) respectively. Conclusion: Strong correlation between TA & TRUS estimation of prostate volume and dimensions for volumes up to 100ml found in our study offers TAUS as a cost effective, less invasive, quick and well tolerable alternative to TRUS. TRUS however may be a reasonable choice for accurate measurements in larger (>100 millilitres) prostates, this needs to be further investigated by a larger sample size.
ABSTRACT
A Field experiment was carried out during 2011-12 rabi to study the spatial distribution of aphid, Uroleucon compositae (Theobald) on safflower. Various indices of dispersion, i.e. variance-mean ratio, dispersion parameter, David and Moore’s index, Charlier coefficient, Index of Lexis and Llyods index of patchiness revealed that safflower aphid followed aggregated distribution throughout the crop growth.
ABSTRACT
Food insecurity, as a major public health problem during the past two decades, has received the attention of population experts, scientists and policy-makers. In Iran, based on daily energy intake, 20.0% and 23.2% of households were food-insecure in 1996 and 2001, respectively. Studies have also shown that food insecurity is 99.2% among households under coverage of Imam Khomaini Relief Committee and 36.2% in the Asadabadi Region. So far, food insecurity has not been assessed directly at national, provincial or district levels. This study determined the prevalence of household food insecurity and some associated factors in the urban areas of Shiraz, Iran. Measurement of food insecurity and determining its determinants can help policy-makers in planning, monitoring and evaluating food security promotion program. In this cross-sectional descriptive-analytical study, 778 households from the urban areas of Shiraz were selected by the multi-stage cluster sampling method. Demographic and socio-economic data were collected using standard questionnaires; household food security was assessed on the basis of the USDA 18-item questionnaire. Factor analysis and the Chi-square test were used for socio- economic status criteria determination and data description, while one-way ANOVA and ordinal and linear logistic regression were used for data analysis and identifying the associated and predictive factors. The software used was SPPS 14. The prevalence of household food insecurity was 44% [food insecurity without hunger 27.8%, and food insecurity with moderate and severe hunger 14.4 and 1.8, respectively]. Food insecurity was greater in female-headed families, those with a larger number of children, or those with children under 18 years old [P=0.05]. It was positively associated with socio-economic status [P=0.0001]. Based on the final ordinal logistic regression, predicting factors for food insecurity were children under 18 years old in the family [CI95%:1.28-2.34, OR:1.73], low socio-economic status [CI95%:6.36-14.44, OR:9.56], and responder [mothers] [CI95%1.01-2.83, OR:1.7]. Household food insecurity exists in Shiraz. Having children under 18 years old in the family and low socio-economic status are the most important causes of household food insecurity. Policies and programs, such as promotion of socio-economic status, and approaches to promote the situation of under 18-year old children, such as school lunch programs, can help reduce food insecurity
