Authors: Hanganu Bianca , Velnic Andreea Alexandra , Petre-Ciudin Valentin , Manoilescu Irina , Ioan Beatrice Gabriela 
Published: December 2017

Abstract
Spinal cord injuries represent a special category of injuries in traumatic pathology, with high morbidity and mortality, which justify their analysis with the aim to identify useful aspects in order to prevent and treat them. We therefore performed a retrospective study on 426 cases in order to analyze epidemiology and medico-legal issues related to spinal cord injuries. The studied items regarded socio-demographic aspects (gender, age, home region), type of lesions (vertebral, spinal cord, association with other trauma), circumstances leading to trauma (cause of the injury, season), data regarding hospitalization (medical condition at the hospital admission, number of days of hospitalization, clinical diagnosis, imaging exploration level) and data resulting from autopsy (diagnosis, toxicological examination). Most of our results are consistent with literature data, except for some epidemiological items, which might be explained with cultural differences, life style and inhomogeneous population. Based on our results, the general conclusion is the need for prevention campaigns, focusing on road traffic accidents and falls (especially in elderly) as the main causes of spinal cord injuries.

Published: December 2017

Abstract
Background: The hemifacial spasm (HFS) defined as involuntary intermittent twitching of the muscles of the face (usually unilateral). The spasms characteristically begin around the eye and then extend to affect other muscles of the ipsilateral face. It is caused by vascular element compressing the facial nerve that may be either the anterior or the posterior inferior cerebellar arteries in most cases. Objective of our work: to describe the operative technique (pearls and common mistakes), the efficacy and morbidity of microvascular decompression technique for hemifacial spasm through mini craniotomy, determine the prognostic factors affecting success rate of the surgery. Material & method: A retrospective study of 23 cases of hemifacial spasm treated by mini craniotomy retro sigmoid approach and microvascular decompression at neurosurgery dept., Mansoura University Hospital in last 10 years was investigated. This include Epidemiological, clinical and imaging details, selected treatment options and patients’ outcome. Results: complete resolving of symptoms was conducted in 19 cases 82.6% while reoperated in 2 cases with improvement in one case. Facial palsy appeared postoperative in 6 cases 4 of them improved in 3 months, transient hearing loss in 4 cases17.4% which improved later, cerebrospinal fluid leak appeared in 3 cases 13% which managed conservatively. Conclusions: MVD relieves symptoms of HFS in about 80% of patients while recurrence still in low percentage. The study reported low permanent Complications and generally transient.

Abstract
Extracranial internal carotid artery aneurysms (EICAA) are uncommon lesion. These aneurysms can be classified as true or false aneurysms, atherosclerotic, dysplastic, infectious, posttraumatic and iatrogenic aneurysms. The most common presentation is central neurologic dysfunction, either a stroke or a transient ischemic attack. The rupture of these aneurysms can lead to severely impairment and can affect the quality of life of the patients or even may lead to death. Management of these lesions is required in most cases to prevent complications, however there is no treatment guideline or expert consensus for the management. We present a case of an unusual EICAA, associated with kinking of the affected vessel and review the literature.

Authors: Kawase T. , Ansari Ahmed , Kato Yoko , Yamada Yasuhiro , Tanaka Riki 
Published: December 2017

AbstractIntroduction: Chronic subdural hematoma in clipped patients of unruptured intracranial aneurysms might lead to sudden neurological deterioration and may need emergency evacuation. We studied the effects of various factors in its etiology. Materials and methods: A retrospective study of 91operated clipped patients of unruptured aneurysms in the year 2014-2015 was taken. Various predisposing factors were studied. Results: Goreisan use was not associated with any reduction in post operative CSDH formation. Arachnoidoplasty and reduced post operative dead space contributed in a reduced formation of CSDH. Conclusion: Older male patients with aneurysms who had been treated with anticoagulant drugs should be considered candidates for additive ARP to prevent the development of postoperative CSDH.

Abstract
Introduction: Neurocysticercosis (NCC) is a common parasitic infection of the central nervous system caused by the larvae of the Taenia solium. Spinal cord involvement is very uncommon. Clinical case: A female patient with a history of NCC presented with chronic and recurrent headache associated with motor and sensory deficit, which develops tonic-clonic convulsion, with spatial disorientation. She also had intracranial hypertension syndrome, meningitis syndrome, and pyramidal sygns suggestive of spinal NCC. Conclusions: Neurocysticercosis usually occurs in developing countries and should be considered as a differential diagnosis of neurological diseases. Early diagnosis and treatment are mandatory, as well as education to the community to primary prevention.

Authors: Gupta Rahul , Singh Abhay , Gunjan Gangesh , Bhatoe Harjinder Singh 
Published: December 2017

Abstract
Intrathecal baclofen therapy is a well-established means of treating intractable spasticity and dystonia in paediatric as well as adult population. Complications of baclofen pump placement include infection, malfunctioning and refraction to baclofen. We report a case of eight year child suffering from spasticity due to cerebral palsy, who developed pseudomeningocoele due to peri-catheter leak. Steps and precaution pertaining to pump implantation in a child are discussed. Baclofen pump insertion in a child needs some extra precautions due to non-availability of pediatric implants and poor built of the pediatric patient to adjust with a bulky device. Preventive measures should be taken to prevent peri-catheter CSF leak.
Cystic meningioma: unusual entity with review of literature
Authors: Maheshwari Vikas , Gill Maneet , Narang Amit , Swamy M.N. 
Published: December 2017

Abstract
Cystic meningioma is a relatively rare condition, radiological appearance of the cystic-solid components of the mass may create a diagnostic dilemma. The presence of a cyst is not a common imaging feature and this makes it difficult to differentiate it from hemangioblastoma, craniopharyngioma, metastasis and gliomas. Cystic meningiomas are present more commonly in children. We present a 60 year old male who presented with seizures and frontal lobe signs. The lesion was suspected as glioma however, postoperative histopathological examination demonstrated as meningioma. Patient showed remarkable recovery after surgery. Complete cyst resection should be considered if it is technically feasible and safe.

Published: December 2017

Abstract
Sinonasal undifferentiated carcinoma (SNUC) is an aggressive malignancy originating in the mucosa lining the walls of the nasal cavity and paranasal sinuses. It is a rare tumor that usually presents in an advanced stage, is highly invasive, and is traditionally reputed to be refractory to even the most radical therapy with an attendant poor prognosis. This is particularly true when it transgresses the cranial base.

Published: December 2017

Abstract
The symbiotic interrelationship of probiotic bacteria and starter lactic acid bacteria is of fundamental importance in many fields of industrial microbiology and it is also a great interest of food technologists. This study deals with the antimicrobial potential of cell-free supernatants of Lactobacillus acidophilus NCFM, L. rhamnosus GG and Fresco culture when cultivated alone or together against 5 strains of Escherichia coli and 5 strains of Staphylococcus aureus. While the effect on E. coli was not proven (average change of final density compared to the control was only ΔNEC,24h = 0.12 log CFU ml-1), the decrease of S. aureus final density in the presence of nisin and cell-free supernatant of L. acidophilus NCFM and Fresco culture was considerable (ΔNSA,24h,nis10 = -1.95 log CFU ml-1 and ΔNSA,24h,NCFM+Fr24 = -0.69 log CFU ml-1, respectively).
Istanbul and Turkey One Year Later. Intriguing–Tense–Inspiring
Authors: Luthar Oto 
Published: December 2017

Abstract
This article reports on a metamorphosis. As a participant in a Marie Curie project called ‘Trans-Making’, the author spent three weeks in Istanbul to see which of three abstract ideas he had considered in advance might match, challenge or subvert existing depictions of one of the most complex metropolitan cities in the world. In clarifying his project proposal, he not only had to face his own private orientalism, but also found that, to come to a basic understanding of the unique metropolis that is Istanbul, he had to observe the anxious present political and cultural changes in everyday life through the longue durée historical lens.

Authors: Vidoni Eric D. , Perales Jaime , Alshehri Mohammed , Giles Abdul-Mannaan , Siengsukon Catherine F. , Burns Jeffrey M. 
Published: December 2017

Background and Purpose:
Individuals with Alzheimer disease (AD) experience progressive loss of independence-performing activities of daily living. Identifying interventions to support independence and reduce the economic and psychosocial burden of caregiving for individuals with AD is imperative. The purpose of this analysis was to examine functional disability and caregiver time in individuals with early-stage AD.

Methods:
This was a secondary analysis of a randomized controlled trial of 26 weeks of aerobic exercise (AEx) versus stretching and toning (ST). We measured functional dependence using the Disability Assessment for Dementia, informal caregiver time required using the Resources Utilization in Dementia Lite, and cognition using a standard cognitive battery.

Results:
We saw a stable function in the AEx group compared with a significant decline in the ST group (4%; F = 4.2, P = .04). This was especially evident in more complex, instrumental activities of daily living, with individuals in the AEx group increasing 1% compared with an 8% loss in the ST group over 26 weeks (F = 8.3, P = .006). Change in memory was a significant predictor of declining instrumental activities of daily living performance (r = 0.28, 95% confidence interval = 0.08 ∞, P = .01). Informal caregiver time was not different between the AEx and ST groups.

Conclusions:
Our analysis extends recent work by revealing specific benefits for instrumental activities of daily living for individuals in the early stages of AD and supports the value of exercise for individuals with cognitive impairment.
Variación horaria en las mediciones de caudales en la cuenca hidrográfica Jesús María con el método del molinete de copas
Authors: Bonilla Valverde José Pablo , Rojas Barrantes Adrián 
Published: December 2017

La realización de aforos puntuales en Costa Rica constituye una práctica común en la evaluación del recurso hídrico para abastecimiento de agua potable. El país cuenta con una base de datos compuesta por mediciones puntuales realizadas en la mayoría de los ríos de Costa Rica con casi cuarenta años de información. En esta un solo dato (aforo puntual) se utiliza para caracterizar todo el mes en que se evaluó. Con el objetivo de corroborar la validez de esta caracterización se realizaron aforos puntuales cada hora para confirmar que la variación horaria es mínima. Los aforos horarios se realizaron durante la campaña de medición de caudales de la cuenca hidrográfica Jesús María, realizada el 9 y 10 de abril de 2013. Las mediciones de caudal se realizaron con el método del molinete de copas según la norma ISO 2537:2007. Una tercera parte de las mediciones presenta una variación menor a ±1 % y más de tres cuartes partes en el rango de ±5 %. En todos los casos, excluyendo la cuenca baja del río Jesús María, las variaciones horarias en las mediciones son menores al 10 % respecto a la mediana. Se concluye que la variación horaria del aforo es relativamente pequeña y, por lo tanto, se valida la base de datos para los meses del final del estiaje. Esta experiencia debe repetirse en la misma cuenca en otras épocas del año y en otras cuencas, para garantizar que la variabilidad temporal no represente grandes diferencias en el caudal.
Carta al Editor Es erróneo hacer una asociación directa entre la detección de <i>Helicobacter</i> spp. y gastritis en caninos
Authors: Suárez-Esquivel Marcela , Barquero-Calvo Elías 
Published: December 2017

It has been proposed that Helicobacter may play a significant role in the generation of gastritis and cancer in dogs. However, despite several independent efforts, there is still controversy regarding the true ability of Helicobacter to cause gastric lesions in these animals. The foregoing is due in part to the fact that gastritis is a multifactorial disease. Studies focused on naturally acquired infections have been unable to establish a positive correlation between Helicobacter colonization and gastritis. Establishing a clear association between the presence of Helicobacter and gastritis may be difficult due to the following reasons: (i) taxonomy of the genus Helicobacter remains unclear, (ii) virulence factors of Helicobacter species that colonize dogs are not well known, and (iii) simultaneous infections have been reported with several species of Helicobacter. Current knowledge in taxonomy and pathogenesis of Helicobacter species is insufficient to differentiate between pathogenic and non-pathogenic strains. Therefore, no direct association should be made between the detection of Helicobacter and gastritis.

Published: December 2017

El virus de Schmallenberg afecta a rumiantes produciendo pérdidas económicas importantes, el cual se transmite a través de artrópodos del género Culicoides, sin embargo, no se descarta la posibilidad de transmisión sexual debido a la presencia del virus en semen, razón por la cual, el Servicio Nacional de Salud Animal de Costa Rica (SENASA), estableció restricciones a la importación de semen de rumiantes procedentes de la Unión Europea en el 2013. En consecuencia, el SENASA realizó un estudio para determinar la presencia o ausencia de anticuerpos contra este virus en muestras de bovinos, ovinos y caprinos. Como resultado de este estudio no se encontró la presencia anticuerpos contra el virus de Schmallenberg en ninguna de las 748 muestras evaluadas, por lo que se concluye que este virus no está circulando en los rumiantes de Costa Rica.

Authors: Beretzky Zsuzsanna , Péntek Márta 
Published: December 2017

Abstract: Introduction: Informal care plays an important role in ageing societies. Aim: To analyse informal care use and its determinants among patients with chronic diseases in Hungary. Method: Patient level data from previous studies in 14 diagnoses were analysed including patients’ EQ-5D-3L health status. Descriptive statistics were performed and a linear regression model was built to analyse determinants of informal care time. Results: 2047 patients (female: 58%) with mean age of 58.9 (SD = 16.3) years and EQ-5D-3L index score of 0.64 (SD = 0.33) were involved. 27% received informal care, the average time of care was 7.54 (SD = 26.36) hours/week. Both the rate of informal care use and its time differed significantly between the diagnoses (p<0.05), the highest were in dementia, Parkinsons’ disease and in chronic inflammatory immunological diseases. Significant determinants were age, EQ-5D-3L scores, gender and certain diagnosis dummys (R2 = 0.111). Conclusions: Informal care use is significant in chronic debilitating conditions. Future studies are encouraged to reveal unmet needs, preferences and further explanatory factors. Orv Hetil. 2017; 158(52): 2068–2078.

Approximate formula for the H/V ratio of Rayleigh waves in incompressible orthotropic half-spaces coated by a thin elastic layer
Authors: Vinh Pham Chi , Tuan Tran Thanh , Hue Le Thi 
Published: December 2017

This paper is concerned with the propagation of Rayleigh waves in an incompressible orthotropic elastic half-space coated with a thin incompressible orthotropic elastic layer. The main purpose of the paper is to establish an approximate formula for the Rayleigh wave H/V ratio (the ratio between the amplitudes of the horizontal and vertical displacements of Rayleigh waves at the traction-free surface of the layer). First, the relations between the traction amplitude vector and the displacement amplitude vector of Rayleigh waves at two sides of the interface between the layer and the half-space are created using the Stroh formalism and the effective boundary condition method. Then, an approximate formula for the Rayleigh wave H/V ratio of third-order in terms of dimensionless thickness of the layer has been derived by using these relations along with the Taylor expansion of the displacement amplitude vector of the thin layer at its traction-free surface. It is shown numerically that the obtained formula is a good approximate one. It can be used for extracting mechanical properties of thin films from measured values of the Rayleigh wave H/V ratio.
A closed-form solution for free vibration of multiple cracked Timoshenko beam and application
Authors: Khiem Nguyen Tien , Hung Duong The 
Published: December 2017

A closed-form solution for free vibration is constructed and used for obtaining explicit frequency equation and mode shapes of Timoshenko beams with arbitrary number of cracks. The cracks are represented by the rotational springs of stiffness calculated from the crack depth. Using the obtained frequency equation, the sensitivity of natural frequencies to crack of the beams is examined in comparison with the Euler-Bernoulli beams. Numerical results demonstrate that the Timoshenko beam theory is efficiently applicable not only for short or fat beams but also for the long or slender ones. Nevertheless, both the theories are equivalent in sensitivity analysis of fundamental frequency to cracks and they get to be different for higher frequencies.
