Supravalvular aortic stenosis in William′s syndrome
No full textWe report supravalvular aortic stenosis in a 12 year old patient who presented with mental retardation, malformed teeth, broad lower lips, pectus carinatum, clinodactyly, kyphoscoliosis with symptoms of shortness of breath. On examination presence of better volume pulse in right radial artery with ejection systolic murmur best heard in right 2nd intercostal space were noted. Patient was diagnosed as having William′s syndrome with investigations demonstrating Supravalvular aortic stenosis with a gradient of 170 mm Hg

No full textThe impact of HIV/AIDS on the quality of life: a cross sectional study in north India
No full textObjective: To determine the impact of Human Deficiency Virus
(HIV)/Acquired Immunodeficiency Syndrome (AIDS) on the quality of life
(QOL) on such patients in North India. Design: A cross sectional
study. Setting: Outpatient setting and wards, Department of Medicine
at a premier tertiary health care center, North India. Participants:
Sixty-eight consecutive HIV/AIDS patients attending Medicine out
patient department and/or admitted to the wards of All India Institute
of Medical Sciences were administered a structured questionnaire by the
HIV nurse coordinator. QOL was evaluated using the WHOQOL-Bref (Hindi)
instrument. Analysis: One way Analysis of Variance (ANOVA) was
performed to find out significant difference between the clinical
categories and socio-demographic variables on QOL domains. Results:
The overall QOL mean score on a scale of 0-100 was found to be 25.8.
Similarly, on the scale of 0-100 the mean scores in the four domains of
QOL in descending order were social (80.9); psychological (27.5);
physical (17.7) and environmental domain (11.65). There was a
significant difference of quality of life in the physical domain
between asymptomatic patients (14.6) and patients with AIDS (10.43)
defining illnesses (p< 0.001) and asymptomatic and early symptomatic
(12) patients (p=0.014). QOL in the psychological domain was
significantly poorer in early symptomatic (12.1) (p< 0.05) and AIDS
patients (12.4) (p< 0.006) as compared to asymptomatic individuals
(14.2). A significant difference in QOL scores in the psychological
domain was observed with respect to the educational status (p<
0.037) and income of patients (p< 0.048). Significantly better QOL
scores in the physical (p< 0.040) and environmental domain (p<
0.017) were present with respect to the occupation of the patients.
Patients with family support had better QOL scores in environmental
domain. Conclusions: In our study, QOL is associated with education,
income, occupation, family support and clinical categories of the
patients
Clinical and echocardiographic diagnosis, follow up and management of right-sided cardiac thrombi
No full textAbstractBackgroundRight-sided cardiac masses are infrequent and have varied clinical presentation. The present study describes the clinical features, echocardiographic findings and management of 19 patients presenting with right-sided cardiac thrombi in a tertiary care center in north India.MethodsThis is a retrospective, single center observational study of consecutive patients over the period January 2003–2008 admitted in our emergency intensive care unit (EICU). We identified 38 patients with right-sided cardiac masses admitted to EICU diagnosed by transthoracic echocardiography of which 19 patients had right-sided thrombus. The echocardiographic findings were reviewed by two cardiologists in all patients. Treatment was not standardized and choice of therapy was based on judgment of attending physician.ResultsThe mean age of patients with cardiac thrombus was 36.6 ± 11.8 years. Right atrial (n = 17) and right ventricle (n = 2) thrombi were associated with deep vein thrombosis (DVT) in 7 (36.8%) and pulmonary embolism in 3 (15%) patients. 13 (68.4%) patients appeared to have in situ mural thrombus. 12 patients were managed with oral anticoagulants, 3 patients underwent surgery and 4 patients were thrombolysed. All the survivors had a mean follow-up of 40 ± 6 months (range – 18–50 months).ConclusionsPrompt echocardiographic examination in an appropriate clinical setting facilitates faster diagnosis and management of patients with right-sided cardiac thrombi. High incidence of in situ mural thrombus and varied comorbidities predisposing to right-sided cardiac thrombi besides DVT and pulmonary embolism need to be recognized. Oral anticoagulation and thrombolysis appear to be the mainstay of treatment with surgery limited for selected patients

Image Watermarking in Curvelet Domain Using Edge Surface Blocks
No full textDigital image watermarking aims to protect the information in an image without significantly affecting visual quality. In this paper, a new image watermarking technique has been proposed that uses Gaussian filters and first-order partial differential matrix to extort the edge surface of a host image. This paper influence on the edge surface curvelet coefficients as human eyes are not equally sensitive to a smooth and an edged surface. To preserve the quality of the artwork and to increase the resistance against attacks, the author utilizes the edge surface area of an image, coarse levels of curvelet transform, and strength parameters. The selection of host coefficients are conforming to the human visual system (HVS) is the uniqueness of the research. The exploitation of the Gaussian filters and first-order partial differential coarse curvelet coefficients and the watermark strength parameter offers robustness against image processing attacks. The standard visual quality perception of HVS evaluation metrics are used to measure the superiority of the presented work
