Outcome of Glansectomy and Skin Grafting in the Management of Penile Cancer
Hugh F. O'Kane,Ajay Pahuja,K. J. Ho,Ali Thwaini,Thaigarajan Nambirajan,Patrick Keane
Advances in Urology , 2011, DOI: 10.1155/2011/240824
Abstract: Purpose. To report outcome data for patients with penile cancer treated surgically with glansectomy and skin grafting. Materials and Methods. We retrospectively reviewed data on all patients undergoing surgical management of penile cancer by a single surgeon between 1998 and 2008. Outcomes in patients who underwent glansectomy and skin grafting were analysed. Results. Between 1998 and 2008 a total of 25 patients with a mean age 60 (39–83) underwent glansectomy and skin grafting. Six patients had carcinoma in situ (CIS); the stage in the remaining patients ranged from T1G1 to T3G3. Mean followup for patients was 28 months (range 6–66). Disease specific survival was 92% with 2 patients who had positive nodes at lymph node dissection developing groin recurrence. One patient developed a local recurrence requiring a partial penectomy. Conclusions. Penile preserving surgery with glansectomy and skin grafting is a successful technique with minimal complications for local control of penile carcinoma arising on the glans. Careful followup to exclude local recurrence is required. 1. Introduction Penile cancer is an uncommon malignancy in the industrialized world, particularly in Europe and in the USA with an incidence of less than 1 per 100?000 of the male adult population. In contrast to this, the incidence in some parts of the developing world is as high as 19 per 100?000 per year [1]. More than 95% of penile cancers are primary squamous cell carcinomas with other uncommon histological types including melanoma, sarcoma, and basal cell carcinomas. Historically, the surgical management of the primary lesion in penile carcinoma has meant either partial or radical penectomy. Oncologically, radical surgical excision has stood the test of time, with excellent local control. These operations are however often mutilating and associated with urinary and sexual dysfunction as well as significant psychological morbidity [2]. In an attempt to reduce the negative impact of radical surgery and retain functional penile length, a variety of therapeutic strategies have been developed particularly for the management of more distal lower-grade cancers. The obvious risk is always that there will be compromise of local oncological control. Oncological outcomes of “penile preserving” surgical techniques should always, if possible, be measured against the gold standard of radical excision. Randomised trials are next to impossible in such an uncommon disease and although widely practiced and results are encouraging, only a small number of centres have published their outcome data on

Electrical impedance tomography based image reconstruction and feto-maternal monitoring in pregnancy  [PDF]

Abstract: Standard methods of monitoring the fetus and maternal health during labor are cardioto-cogram, tocography, ultrasound and magneto-cardiograpghy. These methods have some limi-tations in real time continuous monitoring and cause some degree of inconvenience to the pa-tient and demand special attendance of the ob-stetrician also these methods cannot be used for continuous monitoring of the fetal well being. To overcome the limitations of above techniques, a non-invasive bioimpedance measuring method is proposed. This technique helps in monitoring and recording of the electrical field distribution of a closed object. The output variation on the outer surface is likely to provide information because of fetal movements and related physio-logical parameters. It will also help in the de-velopment of Electrical Impedance Tomography based imaging technique for a closed body system with special reference to fetal monitor-ing in-utero during pregnancy and labor. Also we have developed the data acquisition system of 16 electrodes with software for image recon-struction.
Analysis and Simulations of Routing Protocols with Different Load Conditions of MANETs
Poonam Pahuja,Sanjay Pahuja,Dr. Tarun Shrimali
International Journal on Computer Science and Engineering , 2012,
Abstract: In this paper, we have compared important characteristics of MANET proactive routing protocol (DSDV), reactive protocols (AODV, DSR and TORA) and hybrid protocol (ZRP). Extensive simulations are being carried out with different load conditions of MANETs. The offered network loads in the performance plots are characterized by three parameters i.e. packet size, number of connections i.e. source destination pair and packet arrival rate.

Abstract: Vibration monitoring in high power electric machines, such as generators and transformers, presents some difficulties due to the insulation and EM immunity requirements .However, the negative influence of the electromagnetic interference (EMI) can be a real problem when electrical signals are used to detect and transmitphysical parameters in noisy environments such as electric power generator plants with high levels of EMI. Such problems can be solved using optical fiber sensors, which allow in situ measurements and remote control without electrical wires. The present paper describes a novel fiber optic vibration sensor for health monitoring of electrical machines, which utilizes relatively simple technologies and offers moderate costs. The sensor is optimized for detection of mechanical vibrations in the frequency range 20-100 Hz. Design details and experimental results are reported.
Chronic Leg Ulcers in Drug Abusers
Mittal Radha,Pahuja K
Indian Journal of Dermatology, Venereology and Leprology , 2000,
Abstract: Four young males with chronic non pitting swelling of lower legs associated with multiple ulcers, scars and pigmentation after parenteral drug abuse were observed in the Dermatovenereology department during last one year. Three of them had active ulcers which healed with withdrawal of offending drug, use of systemic and topical antibiotics and B-complex. All cases were referred to the deaddiction centre. The characteristic clinical features helped in the diagnosis even before history of drug abuse was obtained.
Collaborative Decision Support Systems for Primary Health care Managers
Gunjan Pahuja,Rajan Vohra
International Journal of Computer Science Issues , 2012,
Abstract: In this paper, a collaborative DSS Model for health care systems and results obtained are described. The proposed framework [1] embeds expert knowledge within DSS to provide intelligent decision support, and implements the intelligent DSS using collaboration technologies. The problem space contains several Hub and Spoke networks. Information about such networks is dynamically captured and represented in a Meta-data table. This master table enables collaboration between any two networks in the problem space, through load transfer, between them. In order to show the collaboration the sample database of 15 health care centers is taken assuming that there are 5 health care centers in one network.

Abstract: This review highlights the importance of cross-linking with chitosan. Derivatisation of chitosan leads to the cross-linking of chitosan without changing its fundamental skelton structure. Cross-linking agents are broadly divided into two categories i.e Physical and chemical cross-linking; on the basis of interaction with chitosan. The various cross-linking agents used for the preparation of chitosan microspheres and its mechanism of cross-linking have also been described. This article also reviewed the implications of cross-linking agents and the novel applications of cross-linked chitosan matrix.

Abstract: Validation is one of the important steps in achieving and maintaining the quality of the final product. Validation of the individual steps of the process is called process validation. The process is developed in such a way that the required parameters are achieved and it ensures that the output of the process will consistently meet the required parameters during the routine production. If each step of the process is validated, we can assure that the final product is of the best quality. This review covers need of validation, principle of validation, types of validation, phases of validation, strategy for validation.
Movement Control of Robot Using Surface Electromyogram Signal
Mr. S. K. Pahuja Sachin Sharma
International Journal of Electronics Communication and Computer Engineering , 2011,
Abstract: The Electromyogram signals or EMG signals are generated whenever there is any muscular activity. These signals can be detected easily over the surface of the body. As these signals are generated whenever there is any muscular activity, so, we can recognize any muscular activity made by the human by measuring the amplitude of the signal. Based on decision made upon the amplitude of the EMG signal we can take many decisions or we can make machine of our interest. In simplest form any disabled person can turn on or turn of the machines just by contracting his fist. In this paper we have made an offline prototype of such machine which, in our case, will move the robot in one direction whenever there will be a sign of muscle contraction in the recorded EMG signal.
