Interval –valued probabilistic logic for logic programs
Authors: Dieu Phan Dinh , Giang Phan Hong
Published: June 2018

This paper presents an approximate method for probabilistic entailment problem in knowledge bases where a portion of knowledge is given by a sentence in propositional logic accompanied with an interval presenting its truth probalibity. This method reduces the entailment problem to one  of finding “prime implicants” of the target sentence expressed through sentences in the  given knowledge base. It is  shown that in the case of probabilistic logic programs the set of such prime implicants can be found by using the SLD-resolution method for  usual definte logic programs.

A set of rules of inference handling this kind of statements, a deductive reasoning method based on  these rules will be considered. The consistency of the knowledge base will be also investigated.
On the equivalent descriptions of family of functional dependencies in the relational data model
Authors: Thi Vũ Đức
Published: June 2018

The family of functional dependencies (FDs) was introduced by E.F. Codd. Equivalent descriptions of family of FDs play essential rules in the design and implementation of the relation datamodel. It is known [1,3,4,5,7,8,12,13,15] that closure operations, meet-semilattices, families of members which are not intersections of two other members give the equivalent descriptions of family of FDs. i.e. they and family of  FDs determine each other uniquely. These equivalent description were  successfully applied to find many desirable properties of  functional dependency. This paper introduces the concept of maximal family of attributes. We prove that this family is an equivalent description of family of FDs. The concept of nonredundant family of attributes is also introduced in this paper. We present some characterizations and desirable properties of these families.
On adaptive filtering for high dimensional systems under parameter uncertainty and its application to satellite data assimilation in oceanography
Authors: Hoàng S, , Baraille R. , Talagrand O. , Carton X. , Mey P.De
Published: June 2018

In this paper, the adaptive filtering theory, recently proposed and developed the authors of present work [1-9] for stochastic, encountered in the field of data as simulation in meteorology and oceanography, is reviewed. Several important questions on numerical estimation og the gain matrix, model reduction, structural  choices for the gain, filter stability… are discussed. We show the connections of present approach with a standard Kalman filtering. Adaptive filter is implemented along with a Kalman filtering. Adaptive filter is implemented along with a Kalman filter and standard Newton relation method on the four-layer adiabatic Miami Isopycnical Co-ordinate Ocean Model (MICOM) to produce the estimate for the deep oceanic circulation using assimilate synthetic observations of surface height. Numerical results justify high efficiency of the adaptive filter whose performance is slightly better than that of a Kalman filter due to  impossibility to correctly specify the error statistics in a Kalman filter.

On the relatively Pseudo-complement operation in finite RHAs
Authors: Minh Hồ Anh , Nam Huỳnh Văn
Published: June 2018

Refined hedge algebras were introduced and  investigated by Ho & Nam in [6--9]. It is known [9] that every refined hedge algebra (RHA, for short) with a chair of the primary generators is a distributive lattice. In this paper we restrict our consideration to finite version of RHAs (see [7, 9]). It is shown that every finite RHA is a Heyting (pseudo-Boolean) algebra. Furthermore, some computing results for the relatively pseudo-complement operation in  these algebras will be exhibited.

Tubulointerstitial nephritis and uveitis syndrome in children: report of three cases
Authors: Pereira Cátia , Gil Joana , Leal Inês , Costa-Reis Patrícia , Silva José Eduardo Esteves Da , Stone Rosário
Published: June 2018

ABSTRACT Tubulointerstitial nephritis and uveitis syndrome is a rare and probably underdiagnosed condition. Renal and ocular manifestations may not occur simultaneously, making the diagnosis more difficult. Nephritis may be asymptomatic; therefore, renal function evaluation is essential for diagnosis. Urinary β2-microglobulin levels may be particularly useful. Uveitis, mostly anterior, nongranulomatous and bilateral, occurs usually after the onset of nephritis. Treatment includes corticosteroids and, eventually, other immunosuppressant agents. Renal disease is usually benign and resolves spontaneously or after treatment with systemic corticosteroids. Uveitis, however, may be chronic or recurrent. The authors described the cases of three pediatric patients diagnosed with tubulointerstitial nephritis and uveitis syndrome. The goal of this paper was to warn the medical community over the need to screen patients with uveitis for renal disease.
Development of a Hardware/Software System for Proprioception Exergaming
Authors: Kobeissi Ahmad Hassan , Lanza Giacomo , Berta Riccardo , Bellotti Francesco , De Gloria Alessandro
Published: June 2018

Physiotherapy and rehabilitation are getting ever more relevance as an integral part of healthcare devising and employing new, effective methodologies and tools. However, not seldom are such tools boring and difficult to use properly for achieving the given training and therapeutic goals. Exergaming, the combination of physical exercise and video gaming, may help to overcome these issues by offering enjoyment and motivation. However, the literature lacks papers investigating how to integrate such devices into a serious game combining effectiveness and enjoyment. In this paper, we focus on the Balance Board (BB), a device used in gyms and in several health-related applications [1], and present an exergaming system for proprioception training. The system includes a BB, which was instrumented to act as a motion controller for an ad-hoc developed, simple 3D video game. The system aims to provide enjoyable training with the BB, boosting equilibrium exercising through the simulation of downhill skiing. We validated the score computation and tested the efficacy of the system in a user test with 40 participants, in ecological settings. The evaluation concerned user performance and a game experience questionnaire. The results showed statistically significant improvement in players’ ability to use the BB. Users also reported a positive gameplay experience.

Comunalidades entre las narrativas históricas de estudiantes y textos escolares: un análisis cualitativo
Authors: Navarro-Roldan Claudia Patricia , Corredor-Aristizábal Javier Alejandro
Published: June 2018

Este artículo de investigación da cuenta de un estudio cualitativo que usó el análisis de las narrativas para conocer cómo los textos escolares reconstruyen la Independencia de Colombia, y cómo esta reconstrucción se relaciona con las narrativas independentistas de los estudiantes en contextos socioculturales diversos. Se realizaron 21 entrevistas a estudiantes de octavo grado en dos colegios urbanos y dos rurales. Se utilizó un muestreo por conveniencia y el criterio de saturación de las categorías de análisis Se analizaron los textos escolares que los estudiantes usan en sus clases de ciencias sociales. Las narrativas fueron segmentadas y analizadas a partir de tres categorías historiográficas: fuentes históricas, explicación histórica y motor de la historia. Se encontró que la plantilla historiográfica reproducida en los textos para organizar la información y otorgarle significación histórica fue usada por los estudiantes para construir sus propias narraciones históricas; y que coexisten las mismas narrativas independentistas en contextos rurales y urbanos. Se concluyó que los textos reprodujeron una narrativa histórica nacional que estructuralmente no favorece a los estudiantes en la construcción de conocimiento disciplinar sofisticado
Arquitecturas de aspectos sociales en la práctica pedagógica de profesores en formación de lenguas extranjeras
Authors: Castañeda Harold Andrés
Published: June 2018

La investigación local sobre la práctica pedagógica de profesores en formación de lenguas extranjeras ha girado mayoritariamente en torno al papel de la reflexión. Este artículo de investigación propone que es necesario comprender las arquitecturas de práctica que se construyen socialmente en este contexto. El estudio se enfoca en la dimensión social de los modos de saber, hacer y de relacionarse de 184 participantes que diligenciaron un formato de autoevaluación de donde se extrajeron eventos narrativos. El análisis de los eventos narrativos se desarrolló, metodológicamente, desde la perspectiva de la teoría fundamentada. Los hallazgos ilustran tentativamente, entre otros, que una arquitectura plausible de práctica se manifiesta en la intersección de marcos de interpretación propios no siempre reconocidos en la literatura, en posicionamientos vehiculados a través de la mirada del otro y de sus disposiciones para enfrentar contextos diversos de enseñanza y en la acción conjunta aunada al logro de capital social del profesor en formación de lenguas extranjeras.
Aprendizaje, comunicación e innovación en la formación de maestros de lenguas en Colombia
Authors: Ordoñez-Ordoñez Claudia Lucía
Published: June 2018

El presente artículo es una reflexión basada en la experiencia reciente de la autora en innovación pedagógica e investigación sobre la educación para el bilingüismo en lengua materna y extranjera y sobre la formación de profesores de lenguas en nuestro país. Está motivada por la convicción de que el mejor profesor de lengua extranjera en nuestros contextos es el bilingüe, hablante nativo de español, que ha vivido las necesidades y problemas del aprendizaje de una lengua extranjera en un ambiente mayormente monolingüe. La autora reflexiona acerca de teoría y práctica en la formación de profesores de lenguas para el bilingüismo que busca el país, argumentando a favor de una educación que incluya y conecte experiencias relacionadas con la verdadera forma como aprende la gente y experiencias innovadoras de desarrollo del español materno y de la lengua extranjera en contextos específicos y para la comunicación efectiva. El objetivo primordial es formar maestros que entienden que no hay maneras fijas, conocidas y probadas de enseñar lenguas, y que exploran y experimentan permanentemente prácticas pedagógicas nuevas en sus aulas, con la intención de adaptarse a muy variados grupos de aprendices y contextos de aprendizaje y siempre mejorar como maestros. El artículo está escrito en español porque la reflexión que contiene aplica en la formación profesional de docentes de cualquier lengua, materna o extranjera.

Published: June 2018

Objetivo: O presente estudo teve como objetivo descrever o comportamento dos parâmetros antropométricos de jogadores profissionais de voleibol ao longo do período competitivo e investigar a existência de correlação entre o perfil antropométrico e a altura do salto vertical nesses jogadores. Métodos: A composição corporal nos jogadores (n=13) foi determinada por meio da mensuração de 7 dobras cutâneas, utilizando adipômetro. A altura do salto contra movimento foi feita por meio do tapete de contato em 3 tentativas, obtendo a média entre os resultados. A coleta dos dados foi realizada em 3 momentos da temporada competitiva (C1, C2, C3). Foi utilizado a ANOVA one-way e post hoc com Tukey. Posteriormente, foi determinado o coeficiente de correlação de Pearson. O nível de significância adotado foi de p<0,05. Resultados: Não houve diferença estatística em função do tempo para todas as medidas corporais e a altura do salto (p>0.05). Foi observada correlação (C1: r=0,75; C2: r=0,76; C3: r=0,75, p<0.01) entre a massa magra (kg) e a altura do salto (cm). Também, foi detectada correlação (C1: r= 0,92; C2: r=0,92; C3: r=0,93, p<0.001) entre a massa magra (%) e a altura do salto (cm). Conclusão: A massa magra apresentou correlação com a altura do salto em jogadores de voleibol profissional. Os resultados sugerem que a massa magra deve ser monitorada ao longo da temporada competitiva, considerando sua relação com o desempenho de saltos.

Authors: Feitosa de Oliveira Bruna , Aroni André Luis , Galvão Morão Kauan , Verzani Renato Henrique , Bagni Guilherme , Machado Afonso Antonio
Published: June 2018

Objetivo: O objetivo do estudo foi analisar a eficiência de um programa de 8 semanas focado em exercícios respiratórios como técnica de relaxamento antes do treinamento de lance livre, visando aprimorar o desempenho neste fundamento. Métodos: Participaram 9 atletas universitárias de basquetebol feminino, com idades entre 20 e 26 anos e pelo menos 2 anos de prática. Utilizou-se como instrumento o biofeedback para visualizar alterações nos parâmetros fisiológicos periféricos das atletas, e relacioná-los com seus estados emocionais, mensurando: frequência cardíaca, frequência e volume respiratório e condutibilidade da pele. Os testes inicial e final consistiam em 3 séries de 5 lances livres. As atletas foram divididas aleatoriamente em 2 grupos, controle e intervenção, e ambos treinaram durante 8 semanas 3 séries de 5 arremessos, mas somente o grupo intervenção recebeu um treino específico de como utilizar a respiração diafragmática na rotina antes do arremesso. Resultados: Não foram encontrados padrões de acertos entre os grupos, porém nem todas as atletas do grupo intervenção utilizaram a rotina no teste final, o que pode estar relacionado com o curto espaço de tempo destinado à aquisição de novas habilidades psicológicas, inviabilizando que a rotina fosse assimilada pelas atletas. Portanto, o objetivo de aprimorar o desempenho das atletas em 8 semanas não obteve sucesso. Conclusão: Sugere-se um tempo maior de intervenção para que a rotina seja automatizada.

Mapas de susceptibilidad de deslizamientos a partir del modelo de regresión logística en la cuenca del río Oria (Gipuzkoa). Estrategias de tratamiento de variables
Authors: Bornaetxea Estela Txomin , Antigüedad Iñaki , Ormaetxea Orbange
Published: June 2018

Este trabajo presenta una investigación en la cuenca del río Oria (882 km2) (Gipuzkoa), en la que se ha realizado un análisis comparativo entre diferentes estrategias de tratamiento de datos de entrada para la confección de mapas de susceptibilidad de deslizamientos utilizando un modelo de Regresión Logística. Las tres estrategias experimentadas han sido: (i) no se transforma ninguna variable (continua ni categórica); (ii) se transforman las variables continuas en categóricas dividiendo la distribución de los valores en intervalos de igual rango; y (iii) las variables categóricas son convertidas a continuas mediante el cálculo de la densidad de deslizamientos para cada clase. Para los tres modelos así desarrollados, se ha aplicado el mismo inventario de deslizamientos, obtenido a partir de trabajo de campo; y el mismo conjunto de variables seleccionadas a partir de un procedimiento estadístico objetivo. La comparación de los resultados obtenidos ha servido para determinar la conveniencia de transformar las variables categóricas en continuas para su introducción en el modelo de Regresión Logística. Sin embargo, el procedimiento estadístico para la selección de variables no ha sido capaz de detectar el sesgo producido por una de las variables explicativas, que ha quedado patente, únicamente, después de generar los mapas de susceptibilidad. Por eso, adicionalmente, se ha producido un cuarto modelo, y su correspondiente mapa, teniendo en cuenta los resultados de los tres primeros modelos.
Interpretación y cartografía de paleolíneas de costa lacustres mediante fotografías aéreas de alta resolución y datos LiDAR en la laguna de Gallocanta (NE España)
Authors: Gracia Prieto Francisco Javier , Castañeda del Álamo Carmen
Published: June 2018

La laguna de Gallocanta, de 14 km2 de extensión, se localiza entre las provincias de Zaragoza y Teruel. Sufre frecuentes fluctuaciones del nivel de agua, que oscilan entre la desecación total y un máximo de casi 3 m de profundidad. Está expuesta a vientos fuertes y persistentes del NO, que originan oleaje, corrientes y transporte de sedimentos a lo largo de litorales donde son habituales las playas, flechas, cordones y otras formas costeras. La identificación de antiguos cordones litorales del Pleistoceno Superior en canteras situadas en la zona perilagunar, sugiere una extensión mucho mayor del ámbito lacustre en pocas pasadas, alcanzando al menos 45 km2 de lámina de agua, ubicada a más de 15 m de altura por encima del fondo actual. Las llanuras perilacustres existentes entre dichos cordones y la laguna actual albergan registros morfosedimentarios de paleolíneas de costa de tiempos holocenos e históricos. Dada la gran dificultad de reconocer estas morfologías relictas mediante métodos tradicionales, se emplearon dos fuentes de información: fotografías aéreas de alta resolución (1:15.000) y un modelo digital del terreno generado con datos LiDAR con una precisión de 0,2 m. Se analizó la topografía de forma continua extrayendo las curvas de nivel, para obtener una interpretación topográfica de alta precisión. Posteriormente, se integraron los resultados, operando en entorno SIG, y se realizó una inspección de campo. Como resultado se ha obtenido una serie de secuencias de formas litorales relictas escalonadas que rodean completamente la laguna actual con gran continuidad lateral. Se han identificado unos 10 niveles relictos, algunos de ellos con espectaculares formas litorales bien conservadas como flechas con ganchos recurvados, contraflechas, bahías cerradas por islas barrera, sistemas de barras paralelas, paleodeltas, etc. Estas formas permiten una reconstrucción inicial de la dinámica litoral dominante en tiempos pasados.

Authors: Chelombit'ko E G , Korolev S V , Konev A V , Plokhova E V , Doundoua D P
Published: June 2018

Arrhythmia is often detected in cancer patient, from single ventricular premature contractions to sustained ventricular tachycardia, life threatening ventricular fibrillation and sudden cardiac death. Oncology per se, aggressive anticancer treatment, both chemotherapy and radiation and basic cardiac conditions are main causative factors for tachyarrhythmia. In this review we summarize evidence of arrhythmia and emphasize the importance of cardiac monitoring for the early diagnosis, intervention and surveillance of those patients more susceptible to develop proarrhythmia. Oncologists should be fully aware of arrhythmia and the close collaboration between cardiologists and oncologists would result in a better cardiovascular assessment, risk stratification, cardiac monitoring and treatment.

In the study group, the instagram usage frequency was 80.4% and the facebook usage frequency was 78.7%. The content validity ındex value of PIUQ-SF 6 was calculated as 0.90. According to the exploratory factor analysis, 3 sub-dimensional structures consisting of 6 items explained 53.42 % of the total change in PIUQ-SF 6 scores and factor loads of the items in 3 sub-dimensions changed between 0.84-0.89. The Cronbach's alpha coefficient value of PIUQ-SF 6 was 0.82 and the test-retest reliability coefficient value was 0.82. There was a strong positive correlation between PIUS and PIUQ-SF 6. Students who spent more than 5 hours on the Internet were found to get high scores from all 3 sub-dimensions of PIUQ-SF 6. Confirmatory factor analysis values of PIUQ-SF 6 were found at acceptable intervals. As a result of K-Means clustering and ROC analysis, the cut-off score of PIUQ-SF 6 was calculated as 13.Conclusions: As a result, it has been concluded that PIUQ-SF 6 is a valid and reliable measurement tool as well as researches to be carried out in larger and different groups would be useful.

Posterior reversible encephalopathy syndrome (PRES) is a condition which is characterized by symmetric involvement of posterior white matter on brain imaging and neurological impairments such as seizures, altered mental status, headache, and visual disturbances. This entity has been classically described with hypertension, renal failure and eclampsia but it can also been seen in cases with normal blood pressure especially in patients receiving immunosuppressive therapy, chemotherapy and in patients with underlying autoimmune disease. Although PRES has been reported with several autoimmune disorders, association of Posterior reversible encephalopathy syndrome (PRES) with mixed connective tissue disease (MCTD) is very rare, hence we report a case of Posterior reversible encephalopathy syndrome in a patient with underlying mixed connective tissue disease (MCTD).
A study of HPLC patterns in patients of sickle cell anemia with analysis of red cell parameters
Authors: Jawarkar Ashish , Bhatia Varsha
Published: June 2018

Background: Sickle cell disease (SCD) and its variants are genetic disorders resulting from the presence of a mutated form of hemoglobin, hemoglobin S (HbS). In this study we want to profile various types of haemoglobins and their relative percentage in sickle cell cases. Also, we will analyse RBC indices such as Hb, HCT, MCV, MCH, MCHC and RDW-CV.Methods: We analysed blood from 200 patients suspected to have Sickle cell hemoglobinopathies and subjected it to Sickling screening test. All positive cases will be subjected to HPLC to separate constituent haemoglobins and CBC analysis was done to check RBC indices.Results: In sickle cell trait (SCT) patients, there is a significantly higher level of HbA2 and HbS and significantly lower level of HbA. In sickle cell disease patients, there were significantly higher levels of HbA2, HbF and HbS and significantly lower levels of HbA. Both sickle cell trait and sickle cell disease patients had significantly lower levels of haematocrit, MCH and higher RDW CV.Conclusions: While analysing HPLC patterns, appearance of HbS, low levels of HbA and high levels of HbF and HbA2 should raise a suspicion for presence of Sickle cell hemoglobinopathy. There was statistical difference in levels of Hb, HCT, MCH and RDW-CV between cases and controls. High index of suspicion should be maintained when these parameters are on lower side, especially in population who is prone to have sickle cell disorders.

Background: Spinal anaesthesia is the procedure of choice for infraumbilical surgery worldwide. This is usually very easy in young patients but fraught with difficulties in the elderly. Such difficulties may lead to pain, haematoma and infection, all of which pose a significant risk in the elderly. Hence it is imperative to study the common causes of such problems faced during introduction of the spinal needle for the same This will ensure a better management of the problem. The study was done to assess the impact of height, weight and BMI on the ease of introduction of spinal needle for anaesthesia in patients above 65 years of age.Methods: A 500 patients above 65 years of age were selected for the study based on some well-defined inclusion and exclusion criteria. The time period for the study was 1 year. Their height, weight and BMI were then recorded. Then the number of redirections and level (s) required for successful placement of spinal needle were noted for each patient. ≤3 redirections and <1 levels were considered as easy placement of spinal needle. The latter were tabulated separately against the height, weight and BMI of each patient. Relevant statistical tests were also done to ascertain the significance of the findings.Results: Patients with lesser height, weight and BMI took <3 redirections and <1 level for placement of spinal needle and these were statistically significant.Conclusions: Spinal anaesthesia is relatively easy in elderly patients with lesser height, weight and BMI.

Published: June 2018

Background: Tetanus is an acute neurological fatal disorder caused by anaerobic spore forming bacillus Clostridium tetani, which produced an exotoxin (Tetanospasmin) in a wound. Purpose of this study was to find out the clinico-epidemiological factors of tetanus and how we can modify or minimize the outcome of this disease.Methods: This prospective, observational study was conducted in isolation ward in department of general surgery, SMS hospital Jaipur (Rajasthan) from 1 March 2016 to October 2017. Two hundred patients with clinical diagnosis of tetanus, who were admitted in single unit of SMS hospital, recruited in this study. Patients with age less than 1 yr were excluded. After admission, patient’s detailed history and thorough clinical examination done. The day to day progress of the cases was followed till the time of their discharge from the hospital. Outcome variables were age, gender, geographical area, causes of tetanus and site of injury, precipitating factors, role of baclofen, morbidity, cured and mortality.Results: In this study, mean age of patients were 17 years and male to female ratio was 2.44:1. Most of patients were from rural backgrounds with rural to urban ratio of 6.14:1. Overall mortality in present study was 16.5%. The severity of disease directly related with mortality. The mortality for mild, moderate and severe tetanus was 0%, 1.9% and 68.1% respectively.Conclusions: Though tetanus is a vaccine preventable illness, its prevalence is high in our country. The incidence of tetanus can be reduced by: strengthening of primary immunization programme; proper wound management and giving prophylactic tetanus immune globulins along with tetanus vaccine.
SOFA scoring system in assessing prognosis of critically ill surgical and trauma patients: a prospective study
Authors: Kumar Mohan , S. Chandan C.
Published: June 2018

Background: Major trauma, major surgery or sepsis include the bulk of Surgical patients who become critically ill. This relates to significant injury of a single organ system or anatomical part, or multiple injuries, often of varying severity, of different body parts good scoring or predicting system essentially clears this confusion. Predicting the patients’ outcome depends on good scoring system. Scoring systems are composed of degrees of organ dysfunction, organ failure or multiple organ failures, and anatomical derangements which eventually contribute to morbidity and mortality. With the help of such evaluation system. A well-performing ICU prognostic model helps to make meaningful comparison of the hospital’s current performance with the past. But present study focuses on mainly on SOFA score. Sequential organ failure assessment score.Methods: Scoring systems in assessing prognosis of critically ill surgical and trauma patients - a prospective study was undertaken at MVJ Medical Hospital and Research Hospital, Bangalore after the approval from Ethics Committee. The study was carried out in the period of November 2016 to September 2017 and 50 patients were included in the study.Results: Studies have shown that in the SOFA scores; cardiovascular, neurological, and respiratory, renal, haematological and hepatic dysfunctions were independent risk factors for mortality.Conclusions: In this study, extensive study of SOFA score was done from day 1 to the last day. The SOFA score on day 1 was high among non-survivors and survivors which was statistically significant (9.33 v/s 6.62, p<0.001). Also, SOFA score showed significant increasing trend in the first week, especially on first 3 days, which signifies progressive organ dysfunction among non-survivors.

Published: June 2018

Spontaneous isolated superior mesenteric artery dissection is an extremely rare nosological entity, usually occurring with acute abdominal pain. Authors present the case of a 56 - year - old female with spontaneous isolated SMA dissection who was admitted to the hospital with epigastric pain of acute onset. The patient was successfully managed nonoperatively, with anticoagulation starting immediately after diagnosis. Patient symptoms resolved after a few days. There is a discrepancy concerning the treatment of isolated SMA dissection.  Generally, if there is no intestinal necrosis or SMA rupture, conservative treatment is safe and effective as an initial approach.
Simultaneous traumatic dislocation of the hip knee and ankle joints in an ipsilateral limb, does it happen? A case report
Authors: S. N. Lokesh Kumar , Kumar Deepak , Aggarwal Sameer
Published: June 2018

Simultaneous dislocation of three joints the hip knee and ankle joint in an ipsilateral limb is a very rare pattern of injury and only a single case has been reported in the literature, but it is associated with acetabulum fracture. A 34-year-old male had met with a road traffic accident involving left lower limb. Radiographic examination revealed (i) Posterior dislocation of the hip joint without any fracture (ii) Posterior dislocation of the knee joint(iii)Open fracture dislocation of the ankle joint with medial malleolus fracture tibial pilon fracture. The patient underwent an immediate closed reduction of the hip joint by Allis method. Simultaneous reduction of the knee and ankle joint was done and appropriate splintage gave. Open wounds were well debrided and trans-articular fixator was placed over knee and ankle joint. At a second stage, the medial malleolus fracture and tibia pilon fracture were fixed. MRI scan was done which revealed an anterior cruciate ligament injury of the knee. At 6-month follow-up, the patient was ambulating with full weight-bearing on both lower extremities without any assistive devices. There always lies a high risk of hemodynamic instability and other serious and life-threatening injuries due to the high velocity of trauma involved in such cases. The outcome of ipsilateral hip knee and ankle dislocation can vary widely depending on the circumstances and other associated injuries.
A rare case of thyroid tuberculosis

Published: June 2018

Thyroid tuberculosis although known to be a rare entity provides a diagnostic challenge to the clinician. Clinically, radiologically and even histologically proving to be difficult to arrive at a diagnosis. Its incidence according to literature is 0.1-0.4%. Tuberculosis may be found at multiple sites but incidence in the thyroid, pancreas, striated and cardiac muscle is extremely rare. Herein, we discuss a case of a 60 year old female complaining of a swelling in the front of the neck (more on the right side) since 45 days. Clinically it appeared to be a thyroid swelling. An ultrasound showed a bulky right lobe with heterogeneous echoes. FNAC showed features suggestive of a follicular adenoma. Intraoperatively a firm thyroid was palpable and total thyroidectomy was done. Histopathological examination was done revealing langhan giant cells and an area of caseous necrosis, confirming tuberculosis. The patient was started on thyroid replacement therapy and anti-tubercular therapy. The patient had no significant complications in the 6 months follow up period. In tuberculosis endemic areas, one must maintain a high index of suspicion for thyroid swellings which may show foci of tuberculosis, especially if they have an elevated ESR and other foci of tuberculosis.
