Reconstruction of chest, abdominal walls and perineum
Vijaykumar D,Vijayaraghavan Sundeep
Indian Journal of Plastic Surgery , 2007,
Abstract: The structural integrity of the chest and abdominal walls and perineum is frequently altered by cancer extirpation. Advances in reconstructive surgery and the availability of innovative techniques have helped the cancer surgeon to proceed with radical excisions with minimum morbidity. The ability to harvest flaps from distant sites and the availability of good prosthetic materials have now become part of the routine armamentarium of the plastic surgeon engaged in reconstructive surgery of these areas. Newer technologies incorporating tissue engineering may allow the reconstructive surgeon to achieve better functional and aesthetic rehabilitation of these patients.
Irrigation-coupled bipolar cautery unit: A practical, economical, and simple version
Sharma Shekhar,Haji Altaf,Vijaykumar D,Shaji A
Indian Journal of Plastic Surgery , 2008,
Abstract: Hemostasis is a fundamental principle of surgery for which electrocoagulation is universally used. Bipolar electrocautery has an advantage over monopolar electrocautery in terms of the precision of the extent of tissue coagulation and the lateral extent of thermal tissue injury. However, secondary to the thermal changes induced in the tissue due to electric current passage, there is charring of tissue, which adheres to the cautery tip. This, not only decreases its effectiveness, but also, by getting avulsed while removing the cautery tip from the surgical field, causes rebleeding and more trauma to the tissue. Irrigation of the surgical field during application of cautery reduces the charring effect, thereby improving the efficiency and efficacy. Irrigation-coupled electrocautery devices are available but are costly to acquire and maintain. We describe a simple and reliable version of an irrigation-coupled cautery device, which is of immense functional utility in our experience. It decreases the amount of charring of the tissue and its adherence to the bipolar forceps tips, thereby decreasing the frustrating loss of effectiveness and also increases the life of the bipolar forceps as cleaning needs to be less frequent. By virtue of its simplicity and cost-effectiveness, it can be used in almost all hospitals and situations.
Neuroendocrine tumor of vulva: A case report and review of literature
Sheikh Zahoor,Nair Indu,Vijaykumar D,Jojo Annie
Journal of Cancer Research and Therapeutics , 2010,
Abstract: Neuroendocrine tumor (Merkel cell carcinoma-MCC) of the vulva is a very rare entity with less than 15 cases reported in the English literature. It is known for its aggressive behaviour and propensity for early dissemination. The actual cell of origin and etiology of this disease is controversial. In absence of any definite guidelines for management (due to its rarity), extrapolation of data from extra-vulvar MCC seems logical. We present a case of vulvar neuroendocrine tumor who presented at a locally advanced stage.

Wavelet Based Multi-Scale Principal Component Analysis for Speech Enhancement
Mr. Vijaykumar D. Shinde , Mr. C. G. Patil , Mr. Sachin D. Ruikar
International Journal of Engineering Trends and Technology , 2012,
Abstract: The goal of speech enhancement varies according to specific applications, such as to reduce listener fatigue, to boost the overall speech quality, to increase intelligibility, and to improve the performance of the voice communication device.This paper presents Multiscale principal component analysis (MSPCA) for denoising of single channel speech signal. Principle Component Analysis (PCA) is a standard tool in modern data analysis because it is simple method for extracting relevant information from complex data matrix using eigenvalues and eigenvectors. The multiscale principal component generalizes the usual PCA of a multivariate signal seen as a matrix by performing simultaneously a PCA on the matrices of details of different levels. In multi scale Principal Component Analysis (MSPCA) decorrelate the variables by extracting a linear relationship and wavelet analysis. In addition, a PCA is performed also on the coarser approximation coefficients matrix in the wavelet domain as well as on the final reconstructed matrix. By selecting conveniently the numbers of retained principal components, interesting simplified signals can be reconstructed Wavelet analysis of speech signal segments the voice information content at different Wavelet scales. At subband levels or scales multivariate data matrix are formed using Wavelet coefficients extracted from the same scales of voice signals. At each subband matrix or scales, PCA is used for noise reduction. Qualitative performance is evaluated and quantitative performance of denoising effect is measured by input/output signal-to-noise ratio (SNR), segmental SNR and IS measure.

Quality assessment of child care services in primary health care settings of Central Karnataka (Davangere District)
Rashmi,Vijaykumar B
Indian Journal of Community Medicine , 2010,
Abstract: Background: Infectious disease and malnutrition are common in children. Primary health care came into being to decrease the morbidity. Quality assessment is neither clinical research nor technology assessment. It is primarily an administrative device used to monitor performance to determine whether it continues to remain within acceptable bounds. Aims and Objectives: To assess the quality of service in the delivery of child health care in a primary health care setting. To evaluate client satisfaction. To assess utilization of facilities by the community. Materials and Methods: Study Type: Cross-sectional community-based study. Quality assessment was done by taking 30-50%, of the service provider. Client satisfaction was determined with 1 Immunization and child examination-90 clients each. Utilization of services was assessed among 478 households. Statistical Analysis: Proportions, Likert′s scale to grade the services and Chi-square. Results: Immunization service: Identification of needed vaccine, preparation and care was average. Vaccination technique, documentation, EPI education, maintenance of cold chain and supplies were excellent. Client satisfaction was good. Growth monitoring: It was excellent except for mother′s education andoutreach educational session . Acute respiratory tract infection care: History, physical examination, ARI education were poor. Classification, treatment and referral were excellent. Client satisfaction was good. Diarrheal disease care: History taking was excellent. But examination, classification, treatment, ORT education were poor. Conclusion: Mothers education was not stressed by service providers. Service providers′ knowledge do not go with the quality of service rendered. Physical examination of the child was not good. Except for immunization other services were average.
Client Satisfaction in Rural India for Primary Health Care – A Tool for Quality Assessment
Rashmi,Vijaykumar B
Al Ameen Journal of Medical Sciences , 2010,
Abstract: Introduction: The hospital market has today changed from a seller’s market to a buyers’ market, where the patient is all-important. One needs to understand the fact that patients do not flock to a hospital just because its services are cheap, but because of its good name and good image. Objective: To evaluate client satisfaction with the government approach in primary health care. Materials and Methods: Study design: Cross sectional study Sampling: Multistage sampling. Procedure: 1) The district was stratified into taluks 1 Primary Health Center and 1 Primary Health Unit or 1 Community Health Center (where there is a CHC) from each taluk was selected using random numbers. 2) Client satisfaction was determined by systematic random sampling of clients attending the basic health services Results: Client satisfaction in availability of service was above 90% in all services except in accident care where 30% were dissatisfied. Client satisfaction for facilities and equipments was good in all services except leprosy care and tuberculosis care where it was poor. Clients were mainly unhappy with the waiting time in all the services; in few services they expected speciality care like in child care and antenatal care. High risk care during delivery was not much appreciated. Other major problem was unavailability of the health care provider which led to dissatisfaction. Family planning services were graded excellent without any drawbacks. Except for few setbacks all the services had good satisfaction by majority of clients. Conclusion: Client satisfaction is good on a whole. Key words: Client satisfaction, primary health care, efficacy to treat, antenatal care, child care Key Message: The hospital market has today changed from a seller’s market to a buyers’ market, where the patient is all-important in that context we prioritize clients in primary health care too. Clients attending primary health care were mainly unhappy with the waiting time in all the services; in few services they expected speciality care as in child care and antenatal care. Other major problem was unavailability of the health care provider at night times which led to dissatisfaction. Family planning services were graded excellent by the clients.
