Published: October 2016

Background: The objective of the study to assess optimal utilisation of hospital facilities & evaluate their performance in a tertiary care hospital using Pabon Lasso Model using indicators- bed turnover (BTO), bed occupancy rate (BOR) and average length of stay (ALS).Aims and Objective: To assess optimal utilisation of hospital facilities various wards catering to psychiatric, neurological and neurosurgery services in a tertiary care hospital using Pabon Lasso model and to identify strategies for more efficient use of the existing health service resources.Materials and Methods: This cross-sectional descriptive study was carried out in 2015 at the Institute of Human Behaviour and Allied Sciences, Delhi, India. This study involved various wards catering to psychiatric, neurological and neurosurgery facilities in the institute. Their performance was evaluated over 8 year period (2007- 2014) using three performance indicators (BTO, BOR & ALS) to assess optimal utilisation of hospital facilities.Results: Psychiatry department was initially located in quadrant IV in 2007 & shifted to quadrant III in 2014 which suggests department’s good quantitative performance with small proportion of unused beds. Similarly Neurosurgery department was in quadrant I at its inception in 2010, but shifted to quadrant III in 2014. However, Neurology department was located in quadrant III initially (2007), but shifted to quadrant II indicating either excess bed supply or less need for utilisation.Conclusion: Pabon Lasso model can be used by hospital management for evaluating the performance of health services in cost effective manner.Asian Journal of Medical Sciences Vol.7(5) 2016 69-74

Authors: Lahiry Sandeep , Bhowmik Dipak 
Published: October 2016

Myasthenia gravis (MG) is a relatively rare autoimmune disorder in which antibodies form against acetylcholine (Ach) nicotinic postsynaptic receptors at the neuromuscular junction of skeletal muscles. The usual initial complaint is a muscle weakness but can also present as respiratory failure, as in our case. MG is treated with medications such as Acetylcholine-esterase (AChE) inhibitors or immunosuppresants and, in selected cases, thymectomy.Here, we present a case of 32 year old women with MG, who presented with an unexplained respiratory failure. She was stabilized with mechanical ventilation and subsequently treated with immunoglobins and thymectomy.Asian Journal of Medical Sciences Vol.7(5) 2016 100-102

Published: October 2016

Polyarteritis nodosa (PAN) is a rare systemic vasculitis characterized by necrotizing arteritis of small to medium-sized arteries. It manifests as skin ulceration, hypertension, abdominal pain, digital gangrene, subcutaneous nodules etc. Childhood polyarteritis nodosa (CPAN) is a rare and often fatal disease. Clinically, CPAN often is part of the spectrum of Kawasaki disease (KD). There is no specific serological marker for diagnosis and confirmation is based on histopathology. Most common mode of pharmacological therapy includes corticosteroid or cyclophosphamide, along with antimicrobials for secondary infection prevention and plasmapheresis.Here, we present a case of a 16year old boy with multiple skin ulceration, digital gangrene with few non-specific signs and symptoms, diagnosed as a case of PAN, underwent regular therapy and follow-up.

Employees’ Perception Regarding the Role of Specific HRM Practices in Knowledge Intensive Firms
Authors: Iqbal Salman 
Published: October 2016

The purpose of this paper is to investigate the employees’ perceptions about association between specific HRM practices and employees’ knowledge sharing. Based on previous literature, a model is proposed for the study and hypotheses are formulated. The cross-sectional dataset comes from a sample of 390 employees of 19 Pakistani KIFs. Confirmatory factor analyses were employed to evaluate the reliability and validity of the measurement model and the research model was tested using structural equation modeling. The results suggest that specific HRM practices, for instance, recruitment and selection and reward systems show a positive relationship with knowledge sharing, as perceived by the employees of these organisations. We also found a positive relationship among individual and organisational capability in workplaces. A key finding of this study is that recruitment and selection have a much greater impact on knowledge sharing than reward systems. In this study, knowledge-sharing behaviour is examined using specific HRM practices. Findings should be confirmed using a larger sample, as well as through longitudinal study. This study will be beneficial for researchers, practitioners, scholars, organisational leaders and employees. It will also be helpful for those interested in organisational structure and relationships across organisations in knowledge context. This study makes a valuable contribution, given that there is a lack of empirical studies of this nature focusing on the South East Asian region. Our findings are more interesting given that the current study is based on employees’ perception and employees’ views are similar to than that of management’s views in KIFs. Int. J. Soc. Sc. Manage.

Published: October 2016

Efficient health services require the self-confident and capable medical staff. This milestone cannot be achieved without the flexible and supportive leadership. In the developing countries, health sector has been facing the critical issues like lack of staff, management focus, health facilities and other challenges. Therefore, it is the need of time that supportive and flexible environment should be provided to the nurses so that the self-esteem can be increased and efficient health services can be ensured. Moreover, leaders play a vital role to create the flexible environment that increases the nurse’s self-esteem. Thus, the current study investigates the influence of transformational leadership style on the nurse’s self-esteem of public hospitals of Lahore, Pakistan. The self-administered questionnaire was distributed to 200 nurses of two major public hospitals (Mayo hospital and Jinnah hospital) of Lahore, Pakistan through simple random sampling. The results of the current study reveal that transformational leadership style has significant and positive relationship with nurse’s self-esteem. Therefore, health care sector authorities should adopt the transformational leadership style to enhance the nurse’s self-esteem in their sector to ensure the efficient health care services. Furthermore, limitations and recommendations are given in the last chapter. Int. J. Soc. Sc. Manage. Vol. 3, Issue-4: 287-293

ABSTRACT
An important aspect of searching for exoplanets is understanding the binarity of the host stars. It is particularly important, because nearly half of the solar-like stars within our own Milky Way are part of binary or multiple systems. Moreover, the presence of two or more stars within a system can place further constraints on planetary formation, evolution, and orbital dynamics. As part of our survey of almost a hundred host stars, we obtained images at 692 and 880 nm bands using the Differential Speckle Survey Instrument (DSSI) at the Gemini-North Observatory. From our survey, we detect stellar companions to HD 2638 and HD 164509. The stellar companion to HD 2638 has been previously detected, but the companion to HD 164509 is a newly discovered companion. The angular separation for HD 2638 is 0.512 ± 0.″002 and for HD 164509 is

. This corresponds to a projected separation of 25.6 ± 1.9 au and 36.5 ± 1.9 au, respectively. By employing stellar isochrone models, we estimate the mass of the stellar companions of HD 2638 and HD 164509 to be 0.483 ± 0.007 M
⊙ and

, respectively, and their effective temperatures to be 3570 ± 8 K and 3450 ± 7 K, respectively. These results are consistent with the detected companions being late-type M dwarfs.
IMPROVED PERFORMANCES IN SUBSONIC FLOWS OF AN SPH SCHEME WITH GRADIENTS ESTIMATED USING AN INTEGRAL APPROACH
Authors: Valdarnini R. 
Published: October 2016

ABSTRACT
In this paper, we present results from a series of hydrodynamical tests aimed at validating the performance of a smoothed particle hydrodynamics (SPH) formulation in which gradients are derived from an integral approach. We specifically investigate the code behavior with subsonic flows, where it is well known that zeroth-order inconsistencies present in standard SPH make it particularly problematic to correctly model the fluid dynamics. In particular, we consider the Gresho–Chan vortex problem, the growth of Kelvin–Helmholtz instabilities, the statistics of driven subsonic turbulence and the cold Keplerian disk problem. We compare simulation results for the different tests with those obtained, for the same initial conditions, using standard SPH. We also compare the results with the corresponding ones obtained previously with other numerical methods, such as codes based on a moving-mesh scheme or Godunov-type Lagrangian meshless methods. We quantify code performances by introducing error norms and spectral properties of the particle distribution, in a way similar to what was done in other works. We find that the new SPH formulation exhibits strongly reduced gradient errors and outperforms standard SPH in all of the tests considered. In fact, in terms of accuracy, we find good agreement between the simulation results of the new scheme and those produced using other recently proposed numerical schemes. These findings suggest that the proposed method can be successfully applied for many astrophysical problems in which the presence of subsonic flows previously limited the use of SPH, with the new scheme now being competitive in these regimes with other numerical methods.

ABSTRACT
We present time-resolved spectral analysis of the steep decay segments of 29 bright X-ray flares of gamma-ray bursts (GRBs) observed with the Swift/X-ray telescope, and model their light curves and spectral index evolution behaviors with the curvature effect model. Our results show that the observed rapid flux decay and strong spectral index evolution with time can be well fitted with this model, and the derived characteristic timescales (t

c
) are in the range of 23 ∼ 264 s. Using an empirical relation between the peak luminosity and the Lorentz factor derived from the prompt gamma-rays, we estimate the Lorentz factors of the flares (ΓX). We obtain ΓX = 17 ∼ 87 with a median value of 52, which is smaller than the initial Lorentz factors of prompt gamma-ray fireballs. With the derived t

c
and ΓX, we constrain the radiating regions of 13 X-ray flares, yielding R
X = (0.2 ∼ 1.1) × 1016 cm, which are smaller than the radii of the afterglow fireballs at the peak times of the flares. A long evolution feature from prompt gamma-ray phase to the X-ray epoch is found by incorporating our results with a sample of GRBs whose initial Lorentz factors are available in the literature, i.e.,

. These results may shed light on the long-term evolution of GRB central engines.

Authors: Arruda Claúdia , Artico Gabriela , Freitas Roseli , Filho Antônio , Migliari Dante 
Published: October 2016

ABSTRACT

Introduction
Predisposing factors in chronic hyperplastic candidosis (CHC) have been poorly recognized. This study aimed at assessing the prevalence of Candida spp. in areas of the oral mucosa showing greater prevalent rate of CHC, such as the retrocomissural area, the lateral borders of the tongue, and the hard-palate mucosa in four groups of individuals presenting predisposing factors as follows: Smoking habits (group I); patients with low salivary flow rate (SFR) (hyposalivation – group II); patients with loss of vertical dimension of occlusion (LVDO – group III); and control subjects (group IV).

Materials and methods
A total of 44 individuals (age 40–90 years, mean: 55.8 years) were divided into four groups: Group I (11 smokers); group II (10 hyposalivation patients); group III (10 LVDO patients); and group IV (control, 13 healthy subjects). All individuals were tested for Candida-pseudohyphae form by direct examination and for Candida spp. culture growth in samples obtained from the retrocomissural, tongue's lateral border, and hard–soft palatal mucosa.

Results
Direct examination showed a statistically significant prevalence rate for pseudohyphae (p < 0.05) on the retrocomissural and on tongue's lateral borders of individuals with LVDO. A statistically significant (p < 0.05) culture growth for Candida spp. was found on the retrocomissural areas of those with hyposalivation and with LVDO, and on the palate mucosa and on the tongue's lateral borders in the smokers and in the individuals with LVDO when compared with those of the control group.

Conclusion
While direct examination is effective for detecting pseudohyphae, LVDO and tobacco smoking seem to be factors of relevance to the development of CHC.

Clinical significance
Since CHC has been linked to a high rate of malignant transformation, this study analyzes some clinical (and exogenous) factors that may contribute to the development of CHC and addresses some preventive measures to reduce its incidence.

Remineralizing Effect of Topical NovaMin and Nanohydroxyapatite on Caries-like Lesions in Primary Teeth
Authors: Haghgoo Roza , Ahmadvand Motahare , Moshaverinia Sareh 
Published: October 2016

ABSTRACT

Introduction
NovaMin is a synthetic mineral compound composed of calcium, sodium, phosphorus, and silica. It releases crystalline hydroxyl-carbonate apatite (HCA), which structurally resembles the minerals naturally found in the teeth. Nanohydroxyapatite (NHA) is a biocompatible compound with high affinity for tooth enamel. NHA particles morphologically resemble dental enamel apatite crystals. Considering the efficacy of remineralizing agents and the importance of conservative preventive measures, this study aimed to compare the remineralizing effects of NovaMin and NHA on caries-like lesions in primary teeth.

Materials and methods
This in vitro experimental study was conducted on 30 sound human primary anterior teeth with no cracks or fractures. The surface microhardness (SMH) of each tooth was measured at baseline using a Vickers microhardness tester. The teeth were then subjected to remineralization/ demineralization cycles, and artificial caries lesions were created in them. The SMH of each tooth was measured again and the teeth were then randomly treated with toothpastes containing NovaMin or 10% NHA powder for 2 minutes daily for a period of 5 days. The SMH of each was again measured afterward. Data were statistically analyzed using independent t-tests and Mann–Whitney U tests.

Results
The mean SMH was found to be higher in the teeth treated with NovaMin toothpaste (422.67 kgf/mm2) than in the teeth treated with NHA (384.2 kgf/mm2); However, this difference was not statistically significant.

Conclusion
Both NHA and NovaMin were effective for remineralization of caries-like lesions of primary teeth and no significant difference was detected in their efficacy.

Antibacterial Activity of Leaf Extract of Annona muricata and Simarouba glauca on Enterococcus faecalis
Authors: Mathew Jain , George Reshmi , Theruvil Robin , Padavil Tobin C , Tomy Lincy , Kurian Anil 
Published: October 2016

ABSTRACT

Aim
To determine the antimicrobial effect of water extracts of leaves of Annona muricata and Simarouba glauca on Enterococcus faecalis using agar diffusion method.

Materials and methods
Dried leaves of A. muricata and S. glauca were powdered and extracted in a soxhlet apparatus. Enterococcus faecalis was grown overnight in Trypticase soy agar plates. About 10 μL of each extract was placed on agar plates and incubated overnight. The zone of inhibition was measured after 24 hours. About 1% sodium hypochlorite and distilled water were used as positive and negative controls.

Results
The leaf extract of A. muricata showed similar effectiveness as that of sodium hypochlorite, whereas the leaf extract of S. glauca showed only a slight reduction in growth of E. faecalis.

Conclusion
Leaf extract of A. muricata can be developed as an alternative to sodium hypochlorite for root canal irrigants.

Clinical significance
Success of endodontic treatment depends on complete disinfection of the root canals. Root canal irrigants have a major role in complete disinfection of the root canals. Chemical root canal irrigants are more or less toxic to the oral environment. In this study, naturally derived leaf extracts of A. muricata and S. glauca are compared with sodium hypochlorite for its effectiveness against E. faecalis – the most common pathogen found in the root canals.

Impact of Various Irrigating Agents on Root Fracture: An in vitro Study
Authors: Nikhade Pradnya , Tiwari Sukriti , Sudarshan C , Shetty Priyadarshini , Gupta Naveen K 
Published: October 2016

ABSTRACT

Introduction
Irrigating solutions are used for cleaning and removing dentinal debris, and the other remains from pulpal space during biomechanical preparation. Therefore, we evaluated the impact of various irrigating agents on root fracture at 5-minute time exposure.

Materials and methods
We sectioned 60 permanent maxillary premolars with fully formed root structures transversely maintaining the root length of approximately 14 mm. Five study groups were made comprising ethylenediaminetetraacetic acid (EDTA), cetrimide, citric acid, and so on as various irrigating agents. A universal force test machine was used to calculate the force which was enough to fracture each root. Analysis of variance (ANOVA) test was used to access the level of significance.

Results
About 10% citric acid solution as an irrigating agent showed minimal fracture opposing results, whereas 10% EDTA solution showed the maximum fracture resistance of root portion.

Clinical significance
Selection of suitable EDTA concentration that has minimal adverse effect on the mechanical properties of the tooth is very important for the successful management of tooth fracture.

Conclusion
About 10% EDTA provided the highest fracture resistance, necessitating the use of irrigating solution in root canal therapy (RCT). Further research with higher and different study groups is required to search for more efficient irrigating solution to improve the outcome of RCT.
