CORPOARTE E IDENTIDADES: UM ESTUDO SOBRE AS VISUALIDADES JUVENIS NAS ESCOLAS
Authors: Pinto Rosana Da Silva
Published: June 2018

O objetivo da presente pesquisa consiste em investigar aspectos presentes nas apresentações corpóreas de alguns alunos de uma unidade do Colégio Pedro II, com idade entre nove e onze anos. As investigações acerca do tema foram realizadas a partir do seguinte problema: as imagens que os estudantes formulam com suas configurações corpóreas podem ser encaradas como um tipo de criação artística? Nesta reflexão, proponho também, demonstrar que a nossa experiência corporal, que cremos muitas vezes ser individual, está invadida e modelada, desde o início, pela sociedade em que vivemos e por nossas relações. Almejo, desta forma, apontar outras possibilidades de apreensão de um corpo frequentemente entendido como uma realidade cerrada e íntima e sublinhar a sua condição aberta e dinâmica em função da sua mediação social, e assim problematizar estéticas difundidas pelas mídias – que visam caracterizar as etapas da juventude – analisar o papel reservado ao corpo dos estudantes no cotidiano escolar e realizar uma breve análise a respeito de sua participação no processo formativo. Proponho uma discussão acerca das imagens que os jovens figuram com seus corpos a fim de alinhavar outros contornos de nossas referências para o ensino e para nossa visão sobre o humano. Nos capítulos que integrarão esta pesquisa, abordarei o corpo como lugar de criação, real e potencial, como sujeito e objeto de suas próprias construções visuais, destacando também alguns aspectos do seu caráter simbólico.

Epidermolysis bullosa: management complexities for paediatric patients
Authors: Lynne Victoria , Burns Lisa , Handsaker Joanne , Murdoch Julie M
Published: June 2018

The genetic skin condition, epidermolysis bullosa (EB) causes the skin to be fragile and blister. As a result, blisters need to be lanced and the skin needs to be dressed with specialist dressings for protection and to promote wound healing. Method: a prospective case series and product evaluation of the Allevyn™ Gentle Border Lite dressing range was conducted, with four paediatric patients diagnosed with the following types of EB: recessive dystrophic (generalised severe), dominant dystrophic, simplex (generalised severe) and junctional (localised). Specialist EB nurses at Birmingham Children's Hospital conducted the evaluation and compiled the case series. Management and outcomes: clinical, patient and health economic outcomes were captured. The outcomes reported suggest an increase in dressing time wear and a reduction in dressing changes when comparing Allevyn Gentle Border Lite dressings to the patient's regular foam dressing regime. Furthermore, a cost saving measure could be shown. Conclusion: this small case series suggests that the use of the Allevyn Gentle Border Lite dressing range can positively impact the clinical, patient and health economic outcomes of paediatric EB patients.
Au nanowire-VO2 spacer-Au film based optical switches
Authors: Thomas Arun , Savaliya Priten , Kumar Kamal , Suchitta Aakansha , Dhawan Anuj
Published: June 2018

We present a novel optical switch that consists of a 1D array of plasmonic (Au) nanowires present on a vanadium dioxide (

VO
2

) thin film layer, which is further present on top of an underlying plasmonic (Au) film. The optical switching action in this nanostructure arises from the semiconductor-to-metal transition of the

VO
2

spacer layer, i.e., upon phase transition of

VO
2

from its semiconductor state to its metallic state, which can be induced by the application of heat, infrared light, or voltage. The phase transition of the

VO
2

layer results in a change in the reflectance signal from the Au nanowire-

VO
2

spacer-Au film nanostructure. The differential reflectance signal, i.e., difference in the reflection spectra from this nanostructure when the

VO
2

spacer layer is present in its metallic and the semiconductor states, was calculated using RCWA simulations and employed as a measure of switchability. We demonstrate that switchability, as well as the wavelength at which the maximum differential reflectance is observed (i.e., the optimal switching wavelength), can be tuned over a wide spectral regime by changing the structural parameters of these optical switches. Ultrafast switching can be achieved using these optical switches, as the phase transition in the

VO
2

film spacer occurs at femto-second time scales. These optical switches can be fabricated using currently available nanofabrication capabilities.
Mathematical explanation and indispensability
Authors: Vineberg Susan
Published: June 2018

This paper discusses Baker’s Enhanced Indispensability Argument (EIA) for mathematical realism on the basis of the indispensable role mathematics plays in scientific explanations of physical facts, along with various responses to it. I argue that there is an analogue of causal explanation for mathematics which, of several basic types of explanation, holds the most promise for use in the EIA. I consider a plausible case where mathematics plays an explanatory role in this sense, but argue that such use still does not support realism about mathematical objects.
Hilary Putnam on the philosophy of logic and mathematics
Authors: Sagüillo Fernández-Vega José Miguel
Published: June 2018

I discuss Putnam’s conception of logical truth as grounded in his picture of mathematical practice and ontology. i begin by comparing Putnam’s 1971 Philosophy of Logic with Quine’s homonymous book. Next, Putnam’s changing views on modality are surveyed, moving from the modal pre-formal to the de-modalized formal characterization of logical validity. Section three suggests a complementary view of Platonism and modalism underlying different stages of a dynamic mathematical practice. The final section argues for the pervasive platonistic conception of the working mathematician.

Published: June 2018

A pesar de que la población trans presenta un alto grado de exclusión laboral, no hay estudios al respecto en el contexto español. Este estudio exploratorio tiene como objetivos identificar los factores que colocan las personas trans en situaciones de vulnerabilidad frente al mercado de trabajo y establecer los subgrupos que se encuentran en una situación más vulnerable. A partir de entrevistas a personas trans e informantes clave, identificamos 9 factores (género, visibilidad, tiempos, origen y situación legal, posición socioeconómica, apoyo del entorno, nivel formativo, trabajo sexual y estado de salud) que son claves para entender las diferencias dentro del colectivo trans en relación a las posibilidades de inserción. Asimismo, establecemos tres subgrupos que se encuentran en un mayor riesgo de exclusión social.

Indoor Scene Recognition for Micro Aerial Vehicles Navigation using Enhanced-GIST Descriptors
Authors: Anbarasu B. , Anitha G.
Published: June 2018

An indoor scene recognition algorithm combining histogram of horizontal and vertical directional morphological gradient features and GIST features is proposed in this paper. New visual descriptor is called enhanced-GIST. Three different classifiers, k-nearest neighbour classifier, Naïve Bayes classifier and support vector machine, are employed for the classification of indoor scenes into corridor, staircase or room. The evaluation was performed on two indoor scene datasets. The scene recognition algorithm consists of training phase and a testing phase. In the training phase, GIST, CENTRIST, LBP, HODMG and enhanced-GIST feature vectors are extracted for all the training images in the datasets and classifiers are trained for these image feature vectors and image labels (corridor-1, staircase-2 and room-3). In the test phase, GIST, CENTRIST, LBP, HODMG and enhanced-GIST feature vectors are extracted for each unknown test image sample and classification is performed using a trained scene recognition model. The experimental results show that indoor scene recognition algorithm employing SVM with enhanced GIST descriptors produces very high recognition rates of 97.22 per cent and 99.33 per cent for dataset-1 and dataset-2, compared to kNN and Naïve Bayes classifiers. In addition to its accuracy and robustness, the algorithm is suitable for real-time operations.
Multi-objective Optimisation of Multi-robot Task Allocation with Precedence Constraints
Authors: Panchu K. Padmanabhan , Rajmohan M. , Sundar R. , Baskaran R.
Published: June 2018

Efficacy of the multi-robot systems depends on proper sequencing and optimal allocation of robots to the tasks. Focuses on deciding the optimal allocation of set-of-robots to a set-of-tasks with precedence constraints considering multiple objectives. Taguchi’s design of experiments based parameter tuned genetic algorithm (GA) is developed for generalised task allocation of single-task robots to multi-robot tasks. The developed methodology is tested for 16 scenarios by varying the number of robots and number of tasks. The scenarios were tested in a simulated environment with a maximum of 20 robots and 40 multi-robot foraging tasks. The tradeoff between performance measures for the allocations obtained through GA for different task levels was used to decide the optimal number of robots. It is evident that the tradeoffs occur at 20 per cent of performance measures and the optimal number of robot varies between 10 and 15 for almost all the task levels. This method shows good convergence and found that the precedence constraints affect the optimal number of robots required for a particular task level.

Authors: Komşu Ufuk , Samırkaş Komşu Meryem , Boz Hayat
Published: June 2018

In the days of many kinds of literacies required,
it might be observed that economic literacy of individuals play a critical role
mostly for people who run a business under the economical conditions of
contemporary world. Hence, the learning and attitude towards learning
activities have become key instruments for such circumstances. The business
owners in Mersin was the population of this study with the aim of determining
effections between attitudes towards learning and economic literacy and changes
related to some demographical variables . With the sample of 330 participants,
the data of this research was obtained via a questionnaire consisting of
demographic questions and scales of attitude towards learning and economic
literacy. The findings have shown that economic literacy of the business owners
is influenced by the attiudes towards learning. It was also determined that the
age, the level of education and the duration of experience at work may have an
effect on economic literacy and attitudes towards learning. As a result of
findings, it can be inferred that positive learning attitude may increase level
of economic literacy and both scores of attitude towards learning and level of
economic literacy may increase as the age, the education level and the duration
of work experience increase.

The use of salicylic acid as resistance inducers agents in several plants species was well known. Salicylic acid has been believed to play an important role in inducing resistance against some pathogen. This research was aimed to study the role and effectiveness of salicylic acid as inducers for the resistance of some rice variety against bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae. The experiment was arranged in completely randomized factorial design with three factors i.e. rice variety, salicylic acid, and pathotypes, each treatment was replicated three times. The results showed that salicylic acid could prolong the latent period of X. oryzae pv. oryzae pathotypes IV and VIII in paddy rice varieties Conde and Ciherang,  induce the resistance of rice varieties as well as reducing the rate of infection of the two mentioned pathotypes. Salicylic acid was also able to induce the resistance of Conde and Ciherang varieties in order to suppress area under disease progress curve (AUDPC)  of X. oryzae pv. oryzae pathotypes IV and VIII.

Aims/hypothesis

The mechanisms for improved glycemic control after bariatric surgery in subjects with type 2 diabetes (T2D) are not fully known. We hypothesized that dynamic hepatic blood responses to a mixed-meal are changed after bariatric surgery in parallel with an improvement in glucose tolerance.

Methods

A total of ten morbidly obese subjects with T2D were recruited to receive a mixed-meal and a glucose-dependent insulinotropic polypeptide (GIP) infusion before and early after (within a median of less than three months) bariatric surgery, and hepatic blood flow and volume (HBV) were measured repeatedly with combined positron emission tomography/MRI. Ten lean non-diabetic individuals served as controls.

Results

Bariatric surgery leads to a significant decrease in weight, accompanied with an improved β-cell function and glucagon-like peptide 1 (GLP-1) secretion, and a reduction in liver volume. Blood flow in portal vein (PV) was increased by 1.65-fold (P = 0.026) in response to a mixed-meal in subjects after surgery, while HBV decreased in all groups (P < 0.001). When the effect of GIP infusion was tested separately, no change in hepatic arterial and PV flow was observed, but HBV decreased as seen during the mixed-meal test.

Conclusions/interpretation

Early after bariatric surgery, PV flow response to a mixed-meal is augmented, improving digestion and nutrient absorption. GIP influences the post-prandial reduction in HBV thereby diverting blood to the extrahepatic sites.
The Pennsylvania Prescription Drug Monitoring Program: Reducing the Misuse of Prescription Opioids
Authors: Mirigian Lynn S. , Hendrick Laura A. , Pringle Janice L. , Zemaitis Michael A.
Published: June 2018

In 2016, 4,642 Pennsylvanians died from a drug overdose and 85% of these deaths were due to an opioid overdose (U.S. Drug Enforcement Administration and University of Pittsburgh School of Pharmacy 2017). With a 37% increase in deaths from 2015, the Commonwealth’s response to this epidemic has come from several fronts. One valuable resource has been the modernization and implementation of Pennsylvania’s Prescription Drug Monitoring Program (PDMP). PDMPs are state-­run programs that record dispensing of most controlled substances and provide this data to physicians and pharmacists (among others) to inform their practice about possible opioid use disorder by a given patient. This article discusses the role of Pennsylvania’s PDMP in patient care and law enforcement to reduce opioid overdoses in the Commonwealth. Recent evidence is discussed that demonstrates the effectiveness of state-­run PDMPs and their impact on opioid misuse and prescribing patterns. It is important to note that additional research into the effectiveness of PDMPs in preventing opioid-­related morbidity and mortality is needed.

Published: June 2018

Model order reduction is one of the crucial topics facing researchers nowadays. Various methods were conducted for achieving this goal. In this article, genetic algorithm (GA) with dominant poles methods are used to reduce high-order transfer functions (TFs) to lower-order ones. Genetic algorithm is powerful technique used for optimization purposes. In this approach, genetic algorithm is applied to model order reduction to reduce the order of the numerator of TF whereas the dominant poles method is used to reduce the order of denominator of the TF and thus improving accuracy and preserving the same dominant poles for the reduced system as the original model which are two important issues for improving the performance of simulation and computation and maintaining the behavior of the original high order models being reduced

Published: June 2018

The aim of this study is to assess the impact of agricultural industrial effluent discharge on agricultural fields. Soil and crops samples from industrial effluent irrigated agricultural fields were collected from 5 locations in Ilorin, Kwara State between March and August, 2017. Soil and crop samples were analysed for heavy metals (Zinc, Copper, Iron, Lead, Manganese, Cadmium, and Chromium) using the standard procedures. Data collected were analysed for simple descriptive statistics using the Microsoft Excel Package. Results showed Zn level concentration in agricultural produces from in Farms 3 - 5 were found to be in the range of 0.08-0.3 mgkg-1 `falling within the WHO/FAO safe limits of 0.60 mgkg-1. Crop samples collected from Farms 1 & 2 showed the Zn levels higher than the WHO/FAO permissible limit. The concentrations of Cu, Zn, Fe and Cd in agricultural produces were found within the permissible limits of the WHO. The order of accumulation of heavy metals by the agricultural produces were Ewedu > Garden Egg > Flute Pumpkin > Maize > Okro. The consumption of agricultural produces study farms 1 and 2 may pose serious danger to human health. This study recommends treatment of industrial effluent before discharge into the agricultural lands.

Em que pesem as críticas relativas à validade e confiabilidade, o estudo de caso qualitativo tem se tornado cada vez mais popular no campo da gestão. Nesse sentido, pesquisadores têm procurado adaptar ações de validade e confiabilidade para assegurar maior rigor ao estudo de caso qualitativo. A despeito desses esforços, pouco se sabe se as menções explícitas às ações de validade e confiabilidade estão associadas à classificação do periódico onde o artigo foi publicado. Considerando-se essa lacuna, o objetivo desse artigo é o de analisar se menção às ações de validade e confiabilidade em artigos científicos nacionais baseados em estudos de casos qualitativos estão associadas à classificação do periódico onde o artigo foi publicado. Nós construímos uma base de dados composta por 206 artigos publicados em periódicos nacionais mais referenciados e menos bem referenciados e, em seguida, efetuamos uma análise baseada em regressão logística. Os resultados indicam que as menções explícitas de ações de validade de construto e validade interna estão positivamente associadas com a classificação do periódico onde o artigo foi publicado, enquanto que o mesmo não se observa em relação às menções de ações de validade externa e confiabilidade.

Published: June 2018

Este estudo analisa a influência política sobre a contratação de empregados feitos por empresas estatais ou State-Owned Enterprises (SOEs). Acredita-se que os políticos usam a sua influência sobre as SOEs para conseguirem ganhos privados. Portanto, espera-se que em ambientes com fraca governança corporativa as SOEs contratam mais empregados do que as empresas privadas. Foram utilizadas empresas listadas no mercado de ações. A base de dados secundários foi construída a partir de outras três bases. Após o tratamento restaram 96.379 observações de empresas de 41 países entre os anos de 2002 e 2011. Esta pesquisa faz uso da técnica Difference-in-Differences, utilizada para mensurar o efeito da influência política sobre a contratação de empregados após a crise de 2008. Os resultados confirmaram a hipótese do estudo. Pode-se concluir que em ambientes com fraca governança corporativa, os políticos usam a sua influência sobre as SOEs com objetivo de obter ganhos políticos/privados.

Liquefaction resistance of unsaturated sands: experimental evidence and theoretical interpretation
Authors: Mele L. , Tian J. Tan , Lirer S. , Flora A. , Koseki J.
Published: June 2018

Cyclic undrained triaxial tests were carried out on saturated and unsaturated loose specimens of three fine-grained materials. The results confirm that, as the saturation degree decreases, liquefaction resistance sharply increases. In the interpretation of results, the first step was the assessment of the reliability of the use of the 5% strain amplitude criterion to define the attainment of liquefaction. With this aim, the tests were analysed assuming that the soil behaves as an equivalent viscous material. It is shown that the characteristic values of viscosity defining the start and completion of liquefaction depend on soil grading, increasing as the coefficient of uniformity increases. The equivalent viscosity corresponding to a condition of double strain axial amplitude of 5% is fairly constant for all soils. Then, starting from the observation of the relationship between the final volumetric strain and the initial degree of saturation, a theoretical interpretation of the tests is reported. It is shown that the behaviour of the tested sands can be interpreted quantifying the thermodynamic specific energy spent to reach liquefaction, considering the contribution of all phases (soil, water and air). The position of the liquefaction resistance curve depends on the volumetric component of such a specific energy.
The Money View Versus the Credit View
Authors: Baker Sarah S. , López-Salido David , Nelson Edward
Published: June 2018

We argue that Schularick and Taylor’s (2012) comparison of credit growth and monetary growth as financial-crisis predictors does not necessarily provide a valid basis for achieving one of their stated intentions: evaluating the relative merits of the “money view” and “credit view” as accounts of macroeconomic outcomes. Our own analysis of the postwar evidence suggests that money outperforms credit in predicting economic downturns in the 14 countries in Schularick and Taylor’s dataset. This contrasts with Schularick and Taylor’s (2012) highly negative verdict on the money view. In accounting for the difference in findings, we first explain that Schularick and Taylor’s characterization of the money view is defective, both because their criterion for its validity (that rapid monetary growth predicts financial crises) is misplaced, and because they incorrectly take the money view’s proponents as relying on the notion that monetary aggregates are a good proxy for credit aggregates. In fact, the money view of Friedman and Schwartz does not predict an automatic relationship between rapid monetary growth and (financial or economic) downturns, nor does it rest on money being a good proxy for credit. We further show that Schularick and Taylor’s data on money have systematic faults. For our reexamination of the evidence, we have constructed new, and more reliable, annual data on money for the countries studied by Schularick and Taylor.

Exploring How to Simply Approximate the P-value of a Chi-squared Statistic
Authors: Beh Eric
Published: June 2018

Calculating the p-value of any test statistic is of paramount importance to all statistically minded researchers across all areas of study. Many, these days, take for granted how the p-value is calculated and yet it is a pivotal quantity in all forms of statistical analysis. For the study of 2x2 tables where dichotomous variables are assessed for association, the chi-squared statistic, and its p-value, are fundamental quantities to all analysts, especially those in the health and allied disciplines. Examining the association between dichotomous variables is easily achieved through a very simple formula for the chi-squared statistic and yet the p-value of this statistic requires far more computational power.This paper proposes and explores a very simple approximation of the p-value for a chi-squared statistic given its degrees of freedom. After providing a review a variety of common ways for determining the quantile of the chi-squared distribution given the level of significance and degrees of freedom, we shall derive an approximation based on the classic quantile formula given in 1977 by D. C. Hoaglin. We examine this approximation using a simple 2x2 contingency table example then show that it is extremely precise for all chi-squared values ranging from 0 to 50.

With the further development of social economy and science and technology, society has brought new impetus and new challenges for the development of mechanical and electrical engineering. In order to safeguard the sound operation of mechanical and electrical engineering, we must take into account the management effect of project costs while strictly controlling the construction quality of electromechanical engineering projects. There have been some attempts to apply BIM technology to the cost management of electromechanical engineering projects. In this environment, this paper takes the cost management of mechanical and electrical engineering projects of BIM technology as the research object. First, it briefly introduces the theory and characteristics of BIM technology. On the basis of this, it points out the advantages of cost management in combination of electromechanical engineering and BIM technology. Finally, the actual application of this technology in the cost control of electromechanical engineering projects is the final point of view, in order to provide a reference for the project construction time, energy saving, project quality assurance and so on.

Over the past few years, China’s economic development has been swift, and the economic investment in science and technology has gradually increased and it has achieved great development. Therefore, China’s chemical industry has achieved notable achievements. As the chemical industry is closely connected with our daily life and plays a significant role, so to a great extent, people are increasingly concerned about the issue of building chemical engineering. During the construction of chemical engineering projects, design work is particularly important. When an entire chemical engineering project is in production, most of the substances involved in the reaction are either harmful or flammable and explosive. If these materials are not handled properly due to negligence, they will pose a serious threat to the safety and health of workers. Therefore, when designing chemical engineering projects, it is necessary to rationally design the installation of pipeline equipment and to strengthen the pre-control of related materials. In the construction of chemical engineering, the most important procedural step is the layout of equipment piping. Because it is the core device of the whole project, it plays a very important role in the operation. The quality of it will be directly related to the completion of the work of a whole chemical engineering. In addition, considering the personal safety, the design of the project is optimized to ensure the life, health and safety of each worker. Therefore, based on the basic principles of design, this paper studied the design of pipelines and materials for optimization of chemical engineering equipment and carried out a comprehensive analysis to provide a certain reference value for chemical engineering, so as to promote the development of chemical engineering[1].

Background: Reproductive tract infections (RTIs) continue to present major health, social and economic problems all over the world and their complications are the most important causes of morbidity and mortality for women especially in the developing countries. Interest in RTIs and their management has increased tremendously because presence of a RTI in the sexual partner increases the risk of acquisition of HIV. Aim was to evaluate the risk factors in women attending a sexually transmitted infection clinic at a tertiary care centre and prevalence of RTI in our setup.Methods: The present study was conducted on 318 women of reproductive age group (18-45 years) attending the Reproductive tract infection/ sexually transmitted infection (RTI/STI) clinic at our tertiary care centre, they were evaluated for the prevalence of following RTIs: chlamydia, gonorrhoea, syphilis, bacterial vaginosis, trichomoniasis and candidiasis; and their correlation with clinical features and associated risk factors.Results: The factors found to be significantly associated with RTI were illiteracy, unemployment, past history of RTI in patient and presence of RTI in their partner. The prevalence of RTI in our setup reported 9.7%. The prevalence of candidiasis was maximum (11.5%) followed by chlamydia (4.1%), syphilis (4.1%), bacterial vaginosis (1.73%) and trichomoniasis (0.57%).Conclusions: None of the women was found positive for gonorrhoea. No coexistence of any two diseases found in any patient. Most common presentation was genital discharge (52.8%) followed by lower abdominal pain (45.2%).

Background: Dengue fever is a mosquito borne disease caused by flavivirus. Its cases are increasing in India with increasing mortality rate year by year hence, prompt and accurate diagnosis is necessary to prevent morbidity and mortality.Methods: In this study we enrolled 125 clinically suspected cases of dengue. All the collected samples were processed for RT-PCR, NS1 and IgM ELISA. We evaluated NS1 antigen ELISA alone, and combination of NS1 and IgM ELISA against RT-PCR.Results: Among 125 clinically suspected case 67 were positive by RT-PCR and 58 were negative. Sensitivity and Specificity of NS1 ELISA and NS1 with IgM ELISA (in combination) against RT-PCR were 83.58%, 94.82% and 95.55%, 79.31% respectively. (p<0.001).Conclusions: The NS1 ELISA alone was sufficient to detect acute phase of dengue fever, although, combination of NS1 and IgM proved to be most appropriate method for detection of acute as well as late phase of dengue fever.

Background: Neonatal bowel obstruction may result due to defect in the intestine wall which may be classified as neuropathic, myopathic or idiopathic types according to the pathological changes observed. The present study was conducted between September 2014 to December 2015 with the aim to study histomorphological changes and evaluate the role of various IHC markers (calretinin, S-100, CD117) in Hirschsprung’s disease (HD) to assess neuronal dysfunction in these patients.Methods: Thirty cases with clinical suspicion of HD were included in our study. The tissue sections were processed and wax blocks were prepared. Histopathological diagnosis was established on routine H and E. Representative sections were further subjected to IHC staining with calretinin, CD117 and S-100 protein. A descriptive study was carried out. Chi-square was used with P-value less than 0.05 accepted as statistically significant.Results: Out of 30 cases with clinical suspicion of HD, 13 cases were diagnosed as HD, 10 as Non-HD motility disorder whereas 7 were without any definitive diagnosis. All the cases were subjected to IHC staining using calretinin. Out of 13 cases diagnosed as HD, 1 case showed presence of ganglion cell using calretinin. All 7 equivocal cases were accurately diagnosed by calretinin. Thus 12 cases were confirmed HD while 18 were diagnosed as Non HD motility disorder. On statistical analysis, sensitivity (92.3%) of calretinin was lower than specificity (100%). Nerve bundle hypertrophy was observed in 11 cases of HD and 9 cases of Non-HD motility disorder using S-100 as an IHC marker. CD117 was used to demonstrate altered density and distribution of ICCs was statistically significant in cases of Non-HD motility disorder.Conclusions: IHC is being widely used as a reliable adjunctive test in evaluation of motility disorders of bowel. In view of its ease and reproducibility, it can be routinely used, avoiding need for repeated biopsies, and delay in treatment.
