Automatic segmentation of plantar thermograms using adaptive C means technique

Diabetic foot ulcer (DFU) is one of the major concern of diabetes and it is rapidly increasing, in worst case scenario this may lead to amputation. The DFU can be avoided by the early detection and proper diagnosis. Many of the studies carried out highlights that, thermography is the most useful technique to measure the changes in the temperature of plantar surface and alerts to indicate the risk associated with DFU. The distribution of temperature does not have a fixed pattern across the patients, hence it makes the difficulty in measuring the appropriate changes. This gap will provide a scope to improve the analysis technique so as to measure the plantar surface temperature effectively and identify any abnormal changes. In this paper, the segmentation algorithm namely adaptive C means (ACM) for the image segmentation is discussed. ACM is based on the spatial information and this method includes the two stage implementation. In the first stage, nonlocal spatial information is added and in the second stage, spatial shape information is used in order to refine the constraint of local spatial. Outcome of the proposed method shows that ACM is very much effective and it outperforms the other existing methods

Energy aware routing scheme for mobile ad hoc network using variable range transmission

This paper discusses a new energy aware routing scheme which uses variable transmission range. The protocol has been incorporated along with the route discovery procedure of AODV as a case study. Both the protocols are simulated using Network Simulator and comparisons are made to analyze their performance based on energy consumption, network lifetime and number of alive nodes metrics for different network scenarios. The results show that EAR makes effective node energy utilization.Comment: 11 page

Clinico–pathological study of hysterectomy in benign lesions: a study of 379 hysterectomies

Background: Uterus is a very vital reproductive organ and is subjected to many benign and malignant diseases. Hysterectomy is one of the most frequently performed procedures all over the world. Aims and Objectives of the work was to study the clinical benign indications of hysterectomy specimens and to correlate the findings with the histopathological reports.Methods: A prospective and randomized study was performed in 379 cases of elective hysterectomies for benign lesions.Results: Abdominal hysterectomy was performed in 64.6% cases while vaginal hysterectomy accounted for 35.3% cases. The mean age for hysterectomy was 45 years with a range from 14 to 78 years. Patients mostly presented with menstrual irregularities (34.3%) followed by prolapse uterus (30%). The principle indication of elective hysterectomy was leiomyoma and was present in 197(51.9%) patients, followed by prolapse uterus in 134 (35.3%) and dysfunctional uterine bleeding (DUB) in 26 (6.8%) patients. Maximum numbers of cases of leiomyoma, uterine prolapse and DUB were found in age group of 41-50 yrs.Conclusions: The number of abdominal hysterectomy was more than vaginal hysterectomy. Most common presenting feature was menstrual related symptom followed by prolapsed. The main indication for elective hysterectomy was leiomyoma, prolapsed and DUB

Design of Reliable Analog DMTL Phase Shifter with Improved Performance for Ku Band Applications

An analog phase shifter based on distributed MEMS transmission line (DMTL) is designed for Ku band applications. Traditional RF MEMS phase shifter comprising 6 switches has limited phase shift of 37.75° due to instability region. A new concept of stopper is incorporated to achieve high phase shift. In the present paper, optimisation of the analog phase shifter is done to increase its phase shift upto 88.63°. Phase shift is a strong function of capacitance ratio which is increased from 1.75 to 2.95. The maximum operating voltage and mechanical resonant frequency for the phase shifter are 16 V and 8.3 KHz, respectively. The switching time is calculated to 56 μs. The simulated insertion loss of the phase shifter is -1.75 dB with return loss of -20.49 dB at 17 GHz. The simulated results are verified with analytical modelling which are in close match

Fixed drug eruptions: causing drugs, pattern of distribution and causality assessment in a leading tertiary care hospital

Background: It is bitter truth that there is no drug in this world which is without an adverse drug reaction (ADR). After the clinical trials when the drug comes in market or when it is taken by variety of population then actual reality of the drug comes out about its efficacy and adverse drug reactions. Fixed drug eruption is also one such type of ADR in which a specific type of lesions occurs over the skin after the drug is taken.Methods: We have conducted a clinical, observational study, in BPS Government Medical College, Khanpur Kalan, Sonepat, Haryana, India over a period of eight months. In that period we have found 159 patients having adverse drug reactions. Patients of both genders, under all age group were included in the study.Results: Out of 159 adverse drug reactions reports 69 (43.39%) were cutaneous adverse drug reaction report, 45 (28.30%) cases were of fixed drug eruption (FDE). Out of these 45 cases seen, there were 4 males (8.88%) and 41 females (91.11%). Flouroquinolone antibiotics like ciprofloxacin, ofloxacin and norofloxacin were the most common drugs causing fixed drug eruption followed by nitroimadazole antibiotic like metronidazole, tinidazole and NSAIDS like diclofenac, paracetamol and meftal spas in our study. FDE are more common in upper limbs extremities followed by lower limb extremities than face and trunk. Causality assessment was done with the help of WHO UMC scale and we found that association was possible in all the cases.Conclusions: Fixed drug eruptions are one of the major types of adverse drug reactions and should be assessed and reported
