Dear Editor, This was a retrospective study of a paediatric group of patients with lower urinary tract dysfunction of various underlying pathology. The aim of the study was to determine the reliability of single-channel urodynamics study using a single intravesical pressure sensitive catheter to detect some imperative urodynamic parameters including low bladder compliance and detrusor overactivity. And moreover, the authors used pressureflow curves in conjunction with urinary flow curves to

... rmine voiding with straining patterns. The ultimate goal was to determine the feasibility of conducting urodynamic investigations in paediatric populations in the future avoiding the use of a rectal catheter, which adds to the child's distress during the relatively invasive investigation [1]. This has been addressed in previous studies on adult populations [2,3]. The rationale behind the study is plausible and worthy of investigation indeed. However, the methodology followed by the authors of the current study is suboptimal for the following reasons. Firstly, it was a retrospective study; such an interesting idea requires a prospective controlled blinded approach. Secondly, the sample size is small and the study is not sufficiently powered, which is important to justify the significance of the statistical outcomes of the study. In addition, the whole study relies totally on the experience of a single investigator, which makes it very subjective and operator dependent, and consequently the study is lacking important variables including the intra-observer and inter-observers' agreements. Therefore, the reproducibility and accuracy of the study could be questionable. References [1] Cheriyan A, George AJ, Devasia A, et al.

DEVELOPING OF SELF RECLINING WHEELCHAIR (SRWC) was initiated only when we realized that the present market could not provide a self-reliable reclining wheelchair. Mainly our project aims on developing an independent working mechanism so that the person on the wheel doesn't require the help of a caregiver to recline the wheelchair. The present market can provide the reclining wheelchairs which require the help of a second person to recline it for the person on the wheel. This problem of all time

... assistance required for a paraplegic patient can be avoided by using our mechanism. Whenever a paraplegic patient requires the help of a care giver to lie down to a bed he either requires a crutches or the help of a caregiver, instead by depending on our self-reclining wheelchair (SRWC) the patient doesn't require the help of a care giver thus he himself can use the handle on the sides to recline the front and back rests. By developing SRWC we can also take into consideration that stretchers in the hospitals can be replaced by SRWC thereby reducing the space lost mainly in a government hospital of very limited space. Thus the SRWC provides a dual purpose medical support as a wheelchair as well as a stretcher. SRWC's as stretchers in the sense it can be used in simple transportation (i.e from consulting rooms to the labs or rooms concerned or to Xray rooms).Our main objective is to develop a reclining wheelchair which can also be used as an alternative for the stretchers in the hospitals.

The recent developments in full duplex (FD) communication promise doubling the capacity of cellular networks using self interference cancellation (SIC) techniques. FD small cells with device-to-device (D2D) communication links could achieve the expected capacity of the future cellular networks (5G). In this work, we consider joint scheduling and dynamic power algorithm (DPA) for a single cell FD small cell network with D2D links (D2DLs). We formulate the optimal user selection and power control

... as a non-linear programming (NLP) optimization problem to get the optimal user scheduling and transmission power in a given TTI. Our numerical results show that using DPA gives better overall throughput performance than full power transmission algorithm (FPA). Also, simultaneous transmissions (combination of uplink (UL), downlink (DL), and D2D occur 80% of the time thereby increasing the spectral efficiency and network capacity.

We examine theoretically the transmission characteristics of the Single mode-Multimode-Single mode (SMS) fiber structures when the spot sizes of the fundamental modes of the single and multimode fibers do not match. It is observed that in such cases, the transmitted power becomes highly sensitive to the wavelength of operation and the length of the multimode fiber used. The study should be useful in the design of efficient fiber optic microbend sensors and novel wavelength filters using SMS structures.

Ethical businesses can bring prosperity to society without creating harm to people or environment. Most of the huge corporate scams and frauds involve men in comparison to women. Many studies have found that women at the top management positions in businesses are more ethical than their male counterparts. In the context of growing number of women entering into the corporate world and decision-making positions of businesses, this study explores the question whether the ethical sensitivity of

... n is higher than that of men in the Indian context. Sample consists of 258 MBA students from 6 different business schools in the city of Bangalore. Study has used an adapted version of business ethical vignettes created by Longenecker, J. G., McKinney, J. A., & Moore, C. W. (1989). The results showed that the self-reported score of ethical sensitivity of female students is higher than that of their male counterparts. The study has significant implications in terms of promoting more women to the top positions of businesses which might result in more ethical business environment and probably a better and sustainable future for our country.

AbstractInstability of the shoulder joint is common but most of the time it is unrecognized by the treating surgeon. The symptoms can vary from subtle pain to shoulder dislocation. In many cases, there is no history of trauma. The shoulder joint is stabilized by both static and dynamic factors, and treatment is complex, with recurrence more common in young athletic individuals. Open and arthroscopic techniques of stabilization are available with specific indications for each of these methods.

... ne bag (i.e. in case of a paraplegic patient) and also as a pack to keep the amenities for regular purpose. The main advantage of this Multi-Utility Stretch Chair (MUSC) as a stretcher is that the wheelchair can be converted directly to the stretcher with variable height postures and there is a detachable tray to hold the oxygen cylinder. The reclining back and front rests works on the links connected using pin joints. The entire MUSC is foldable, so the space utilization by this product is minimized. There by reducing the extra space formed by an individual wheelchair and a stretcher by acting on a single unit. The MUSC can be collapsed and folded it can be made compact for the ease of carrying, transporting. Most of the parts in the stretch chair are detachable as the demand varies with purpose of use. When MUSC is used as a wheelchair, depending on the need of the individual a detachable propelling mechanism to favor the ease of mobility can be provided. The materials used for fabricating the unit is Structural Steel which reduces the weight of the unit. The load analysis and real time load analysis was done on using ANSYS R15. The product and the results were found good. I. A unique product as an alternative for individual wheelchairs and stretchers and thereby achieving the effective utilization of space.

Objective: To determine if the interpretation of urodynamic studies (UDS) in children without a rectal catheter may be similar to multi-channel studies, as UDS in children are challenging and can sometimes be difficult to interpret. Patients and methods: In this retrospective pilot study, 115 paediatric pressure-flow studies were included. A blinded investigator was given two sets of UDS traces. The first set had the vesical trace of all children and the second set had the multi-channel trace.

... he agreement between the interpretations of both the sets was tested by Cohen's κ, and sensitivity, specificity, and predictive values were expressed with 95% confidence intervals (CIs). The voiding pattern was compared and Pearson's correlation coefficient was used to analyse the pressure at maximum urinary flow (Qmax). Results: The most common indications for UDS were neurogenic bladder and posterior urethral valves. The interpretation of compliance and detrusor overactivity by single-channel analysis had a positive predictive value of 92.1% (95% CI 84.7-96.1%) and 89.4% (95% CI 78.3-95.6%), respectively, and a negative predictive value of 100% and 97.1% (95% CI 89.5-99.2%) respectively, in comparison to multi-channel analysis. Children with underactive detrusor were identified reliably by analysing the straining pressure pattern and flow curve. Amongst children who voided, the pressure at Qmax showed a moderate correlation (Pearson's coefficient = 0.53) between the two groups. Conclusion: Rectal catheters may be avoided in a carefully selected group of children undergoing UDS who only need filling phase assessment.
