Teaching of Integrated Management of Patients with Hypothyroidism During the Cycle of Specialization “General Practice - Family Medicine”
Authors: Sheyko Svetlana , Kolb Nataliya , Gordyeyeva Alisa , Karina Kravchenko
Published: April 2018

Pathology of the thyroid gland is an actual medical and social problem of our time. It is due to the increasing prevalence of thyroid diseases and the negative impact of thyroid dysfunction on somatic, reproductive and mental health of the population. In addition, hypothyroidism is associated with an increased risk of developing coronary heart disease, myocardial infarction, chronic heart failure and cardiovascular mortality regardless of gender, age, and past cardiovascular diseases.The objective of the research was to improve the quality of training medical interns in the specialty “General Practice - Family Medicine” through the improvement of teaching the topic “The Integrated Management of Patients with Hypothyroidism”.Discussion. Postgraduate education involves training of medical interns specializing in general practice and family medicine to independent work at the primary health care facility. An essential internship component is the assimilation of practical skills.Conclusions. Further improvement of practical training of medical interns in the specialty “General Practice - Family Medicine” when teaching “The Integrated Management of Patients with Hypothyroidism” is a complex process that requires organizational measures, specific algorithms for managing patients, as well as a continuous improvement of academic, medical and diagnostic, educational work and technical support of the classes.
�Wish You Were Here�: Examining Characteristics, Outcomes, and Statistical Solutions for Missing Cases in Web-Based Psychotherapeutic Trials (Preprint)
Authors: Karin Eyal , Dear Blake F , Heller Gillian Z , Crane Monique F , Titov Nickolai
Published: April 2018

BACKGROUND

Missing cases following treatment are common in Web-based psychotherapy trials. Without the ability to directly measure and evaluate the outcomes for missing cases, the ability to measure and evaluate the effects of treatment is challenging. Although common, little is known about the characteristics of Web-based psychotherapy participants who present as missing cases, their likely clinical outcomes, or the suitability of different statistical assumptions that can characterize missing cases.

OBJECTIVE

Using a large sample of individuals who underwent Web-based psychotherapy for depressive symptoms (n=820), the aim of this study was to explore the characteristics of cases who present as missing cases at posttreatment (n=138), their likely treatment outcomes, and compare between statistical methods for replacing their missing data.

METHODS

First, common participant and treatment features were tested through binary logistic regression models, evaluating the ability to predict missing cases. Second, the same variables were screened for their ability to increase or impede the rate symptom change that was observed following treatment. Third, using recontacted cases at 3-month follow-up to proximally represent missing cases outcomes following treatment, various simulated replacement scores were compared and evaluated against observed clinical follow-up scores.

RESULTS

Missing cases were dominantly predicted by lower treatment adherence and increased symptoms at pretreatment. Statistical methods that ignored these characteristics can overlook an important clinical phenomenon and consequently produce inaccurate replacement outcomes, with symptoms estimates that can swing from −32% to 70% from the observed outcomes of recontacted cases. In contrast, longitudinal statistical methods that adjusted their estimates for missing cases outcomes by treatment adherence rates and baseline symptoms scores resulted in minimal measurement bias (<8%).

CONCLUSIONS

Certain variables can characterize and predict missing cases likelihood and jointly predict lesser clinical improvement. Under such circumstances, individuals with potentially worst off treatment outcomes can become concealed, and failure to adjust for this can lead to substantial clinical measurement bias. Together, this preliminary research suggests that missing cases in Web-based psychotherapeutic interventions may not occur as random events and can be systematically predicted. Critically, at the same time, missing cases may experience outcomes that are distinct and important for a complete understanding of the treatment effect.
Niñez inmigrante e interculturalidad escolar en el norte de Chihuahua
Authors: Segura Herrera Tamara , Hernández-Hernández Oscar Misael
Published: April 2018

En el contexto mexicano, la interculturalidad constituye un discurso de reconocimiento y respeto de la diversidad cultural, especialmente de los pueblos indígenas. El objetivo del artículo es explorar cómo se construye la interculturalidad entre niñas y niños inmigrantes, de origen indígena y mestizo. El supuesto de partida es que la interculturalidad también es un proceso interactivo de comunicación entre personas de culturas diferentes. La metodología está basada en los resultados de un estudio antropológico realizado en el Centro de Atención Integral para Niños Migrantes, en Ascensión, Chihuahua. Con base en observaciones y entrevistas, se identificó que la niñez inmigrante construye la interculturalidad en las aulas, en las áreas recreativas y durante el trayecto a la escuela. Por tanto, la conclusión es que lo hacen en dichos espacios escolares, a través de relaciones y significados, a veces en disputa, que tejen entre sí mismos y con el personal docente.

Gobierno dividido y disciplina partidista: aplicación de un modelo de dinámica parlamentaria para el Congreso del Estado de Baja California
Authors: López Guzmán Cuauhtémoc
Published: April 2018

La relación entre las fracciones parlamentarias está sujeta a condiciones partidistas e institucionales que afectan la conducta y decisiones de los legisladores. Con la intención de sistematizar y jerarquizar la racionalidad de la acción política de los diputados, se diseñó un modelo de dinámica parlamentaria. El modelo se derivó del estudio de los episodios de conflicto y colaboración que ha vivido el Poder Legislativo en Baja California, tanto con el Poder Ejecutivo como entre sus integrantes.
Autonomía, sociedad y Estado
Authors: Brom Juan
Published: April 2018

En el siguiente artículo, el autor hace un breve y conciso análisis sobre el concepto de autonomía en el ámbito académico. Para ello, lo vincula con la noción de libertad, ya que a partir de esa unión es posible concebir el origen de la universidad, entendida como una institución educativa, en donde los profesores, los alumnos y las autoridades académicas pueden fundar sus acciones regidas por sus propios criterios de juridiscción y organización. Para el autor, el origen de la autonomía de la Universidad Nacional Autónoma de México no fue sencillo; sin embargo, logró avances sustanciales para fortalecer la educación en nuestro país. Es por ello que su estudio toma como punto de referencia la experiencia de la UNAM para explicar y estudiar un concepto que ofrece una gran variedad de estudios y propuestas.
El realismo y el neorrealismo estructural
Authors: Vargas Hernández José Guadalupe
Published: April 2018

El objetivo de este trabajo es analizar los enfoques teóricos metodólogicos del realismo y el neorrealismo. Se parte del supuesto de que la teoría realista ayuda a solucionar las fragilidades y los peligros sociales en el contexto de una ideología conservadora y de una teoría elitista de la democracia. El acercamiento realista compite con el neorrealismo o realismo estructural y la teoría institucionalista. Las concepciones neorrealistas e institucionalistas de las instituciones, consideran que éstas son necesidades funcionales para generar orden. Sin embargo, ni la teoría neorrealista ni tampoco las institucionalistas tratan adecuadamente las variaciones de tiempo y espacio.
Los increíbles errores de Lijphart
Authors: Suárez-Iniguez Enrique
Published: April 2018

El artículo presenta algunas precisiones, en el ámbito de la filosofía política, relacionadas con la aportación intelectual de uno de sus más recientes exponentes, Arend Lijphart. En opinión de Suárez-Iñiguez, Lijphart ha propuesto algunas ideas en el campo de la ciencia política, que por sí mismas dificultan la comprensión de temas tales como: la democracia moderna, los sistemas políticos o la participación política. A través de una selección de preceptos, el autor desglosa las que a su parecer, pueden ser las principales debilidades de las aportaciones de Lijphart.
Equilibrios políticos en las entidades federativas
Authors: Montero Bagatella Juan Carlos
Published: April 2018

El artículo analiza la concentración y dispersión del poder político en las entidades federativas, al identificar los incentivos para que se ejerza un contrapeso real frente al Poder Ejecutivo. El estudio analiza la integración de las legislaturas estatales, apoyándose del Número Efectivo de Partidos, así como del análisis sobre la competitividad electoral en las elecciones de gobernador. En las conclusiones, se afirma que la inexistencia de los equilibrios políticos es consecuencia de que la alternancia no ha conducido a una mayor pluralidad, por lo que no se ha generado un cambio institucional.
Élite episcopal y poder en la Iglesia Católica en México
Authors: Godínez Valencia Vicente
Published: April 2018

El presente trabajo centra la atención en la estructura actual de la Iglesia Católica en México, mediante la cual se ubica, históricamente, a ésta como un poder "fáctico" en el ámbito sociopolítico. Ciertamente este acercamiento a la Iglesia no es idéntico, ni tiene la misma naturaleza que tiene una institución política, pero sí tiene analogías. De allí que los peligros son también análogos, no idénticos. Un análisis de la Iglesia en su mera dimensión institucional, comete el error de reducir el todo de la Iglesia a una de sus partes (la jerarquía), situación que sin duda empobrece su conocimiento.

A partir de los materiales existentes, es posible señalar que los estudiosos se han centrado más en la producción legislativa y menos en el cumplimiento de las funciones sustantivas de un Poder Legislativo. Se pretende plantear los asuntos sustantivos a analizar en el caso de los congresos locales, considerando las herramientas heurísticas conocidas, y haciendo énfasis en factores que a menudo se dejan de lado en los análisis.
¿Es realmente “deseable” la cobertura universal?
Authors: Leal F. Gustavo
Published: April 2018

El trabajo organiza una suerte de catálogo sobre los riesgos presentes en algunas de las propuestas alternativas en curso para la reorientación del asunto público en la gestión de la política de salud y seguridad social. Se revisan los términos con que ellas llaman a establecer, urgentemente, sistemas “universales”, pero sin detenerse a caracterizar sus contenidos. Finalmente se postula que un tal proceder puede culminar reproduciendo el “universalismo” de paquetes básicos que animó las estrategias panistas de la última década.

Paradojas de la transición democrática: autoritarismo subnacional en México
Authors: Campos González Sergio Alonso
Published: April 2018

El autor argumenta que el proceso de democratización en México se gestó desde el ámbitolocal, pero sus consecuencias y alcances más importantes se dieron en el ámbito nacional através de una serie de reformas legales que garantizaron una competencia real y permitieronel aumento en la competitividad electoral. Esta situación planteó problemas para el procesode democratización en el ámbito subnacional, ya que en muchas regiones la transición llegó demanera marginal, creándose condiciones para lo que se han denominado enclaves autoritarios.

Los libros de ajedrez en España (c. 1770-1899): bibliografía histórica
Authors: Brasó i Rius Jordi
Published: April 2018

Se presenta un repertorio bio-bibliográfico y un estudio bibliométrico histórico de las obras de ajedrez en España, desde finales del siglo XVIII hasta finales del siglo XIX. Se ha utilizado una metodología basada en la búsqueda y análisis en los fondos documentales de la época y en las bases de datos de las bibliotecas actuales, principalmente de España. La fase interpretativa, junto con un análisis estadístico de cuatro factores –periodo de publicación de las obras, lugar de edición, originalidad o traducción, y tipología– permite describir cada una de las obras de ajedrez publicadas en España, además de contextualizarlas con el momento social de la época. El estudio bibliométrico refuerzaasí el análisis interpretativo sobre la producción  ajedrecística española.
Perfiles de creación de microempresas en las zonas rurales: el caso de Santa Bárbara Almoloya, Cholula, Puebla
Authors: Remilien Emmanuel , Sánchez Hernández Miguel , Hernández Salgado José Hilario , Servín Juárez Roselia , Carranza Cerda Ignacio
Published: April 2018

Actualmente el emprendimiento tiene gran importancia, tanto para emprendedores como para instituciones públicas y privadas. La creación de empresas se vuelve un tema de investigación importante. El objetivo de este trabajo es determinar las diferencias que existen entre la manera de crear las microempresas. El trabajo se desarrolló en la comunidad de Santa Bárbara Almoloya con 73 microempresarios. Mediante un cuestionario se levantó la información necesaria y se han podido formar cuatro grupos que se diferencian entre sí, tanto en capitales financiero, social y humano como en motivaciones. Se concluye que los objetivos y el capital financiero son los elementos indispensables para la creación de las microempresas, pero este último pierde su importancia si las personas tienen un nivel de capital social alto. Las implicaciones de este trabajo sirven para los interesados en la promoción del emprendimiento en el medio rural, como instituciones de microfinanzas (IMF), gobierno e investigadores, así como futuros emprendedores.
Derechos al uso del agua y estrategias de apropiación en la región semiárida de Puebla, México
Authors: Ocampo Fletes Ignacio , Parra Inzunza Filemón , Ruiz Barbosa Ãlvaro Ernesto
Published: April 2018

El estudio muestra las capacidades de las comunidades rurales para hacer frente a la escasez física del agua en una región semiárida del sur del estado de Puebla, México. Se analizaron las distintas fuentes de agua, el derecho a su uso y las estrategias de apropiación que han establecido los grupos sociales. Se aplicó una encuesta a 221 familias de 30 comunidades en nueve municipios y se realizaron transectos y talleres. Los resultados muestran que la apropiación del agua en condiciones de escasez requiere el reconocimiento del territorio para identificar las distintas fuentes de agua y la propiedad de la misma, la construcción de acuerdos locales y diferentes estrategias acordes a los recursos materiales, económicos y humanos de cada usuario. El derecho al uso del agua está relacionado con la propiedad del espacio natural (familiar o individual, comunitario o comunal y estatal) y a la propiedad de la fuente del agua (acceso privado, comunal y abierto o libre). Se concluye que la escasez física del agua ha obligado a los grupos humanos a reconocer su espacio físico y ecológico, y a desarrollar diferentes estrategias para apropiarse de un recurso al que tienen derecho.

Authors: Vázquez Martínez Ignacio , Jaramillo Villanueva José Luis , Bustamante González Ãngel , Vargas López Samuel , Calderón Sánchez Francisco , Torres Hernández Glafiro , Pittroff Wolfgang
Published: April 2018

En México existe escasa información de la producción de ovinos en zonas de clima templado, a pesar de representar un importante medio de vida para la población rural. Este estudio tuvo como objetivo analizar la estructura de los sistemas de producción y tipificar las unidades de producción ovinas de la región templada de los estados de Puebla y Tlaxcala. Los datos fueron colectados por entrevistas y observación directa, registrando en un cuestionario variables sociales y técnicaseconómicas en una muestra estadística de 221 productores de ovinos. La estructura del sistema de producción se determinó con análisis factorial. Las tipologías de las unidades de producción ovinas se agruparon con análisis cluster. El análisis factorial identificó al tamaño del rebaño, la producción de corderos, y la compra y producción de granos y forrajes como las variables que explicaron la mayor varianza de las unidades de producción. Se identificaron tres tipos de agrupaciones de unidades de producción: familiares de subsistencia (60.6 %), asociación ovino-cereales (32.1 %) y extensivas de montaña (7.3 %). En la región de estudio la producción de ovinos depende del tamaño del rebaño, producción y disponibilidad de forraje nativo y de la disponibilidad de mano de obra para generar ingresos económicos.

On derivations and generalized derivations of bitonic algebras
Authors: Yon Yong , Özbal Şule
Published: April 2018

We introduce the notion of bitonic algebras as a generalization of dual
BCCalgebras, and define the notion of (r,l)-derivations, (l,r)-derivations
and generalized (r,l) and (l,r)-derivations on the bitonic algebras. Then we
study the properties of the derivations and the generalized derivations on
the bitonic algebras and the commutative bitonic algebras. Finally, we show
that every generalized derivation of commutative bitonic algebras is a
derivation.
Perfect roman domination in regular graphs
Authors: Henning Michael , Klostermeyer William
Published: April 2018

A perfect Roman dominating function on a graph G is a function f : V (G) ?
{0,1,2} satisfying the condition that every vertex u with f(u) = 0 is
adjacent to exactly one vertex v for which f(v) = 2. The weight of a perfect
Roman dominating function f is the sum of the weights of the vertices. The
perfect Roman domination number of G, denoted ?pR(G), is the minimum weight
of a perfect Roman dominating function in G. We show that if G is a cubic
graph on n vertices, then ?pR(G) ? 3/4n, and this bound is best possible.
Further, we show that if G is a k-regular graph on n vertices with k at least
4, then ?pR(G) ? (k2+k+3/k2+3k+1)n.
SQP alternating direction method with a new optimal step size for solving variational inequality problems with separable structure
Authors: Bnouhachem Abdellah , Rassias Themistocles
Published: April 2018

In this paper, we suggest and
analyze a new alternating direction scheme for the separable constrained
convex programming problem. The theme of this paper is twofold. First, we
consider the square-quadratic proximal (SQP) method. Next, by combining the
alternating direction method with SQP method, we propose a descent SQP

with a new step size ?k. Under appropriate conditions, the global
convergence of the proposed method is proved. We show the O(1/t) convergence
rate for the SQP alternating direction method. Some preliminary
computational results are given to illustrate the efficiency of the proposed
method.

Condensed tannins (CT) in legume forages vary not only in concentration and
structure, but also in the portion of soluble and protein- and fibre-bound
fractions. This study aimed to assess the changes in the total CT level as
well as relative abundance of the three CT fractions from fresh to wilted,
ensiled or pelleted legumes like in birds foot trefoil (two cultivars) and
in sainfoin (one cultivar). Each legume underwent three consecutive
harvests, of which the first two were wilted. Additionally, wilted legumes
were either ensiled (first harvest) or transformed into dehydrated pellets
(second harvest). For each harvest, total CT and the percentage of soluble,
protein- and fibre-bound CT differed (P < 0.01) among plants. The total CT
content was similar after wilting but was lower (P < 0.05) after ensiling.
After wilting, ensiling and pelleting the portion of soluble CT was lower in
favour of protein-bound CT portion. However, time of harvest affected (P <
0.05) total CT and the percentage of soluble and protein-bound CT. Thus,
measuring the bound-fraction should not be ignored in the determination of
CT content since this fraction, together with the soluble fraction, might
protect protein from ruminal degradation.

The preservation of semen for Artificial insemination (AI) required the use
of extender, which served as a buffer media to keep the sperm cell in good
condition for fertilization. In this study, fluted pumpkin Telfairia
occidentalis leaf extract (TOLE) potential as an unconventional boar semen
extender was compared to Beltsville thawing solution (BTS), a conventional
semen extender over a 48hr storage period. Aqueous solution of TOLE was
prepared at three (3) concentration levels (25, 50 and 75%). Fresh
ejaculates from boar were extended at (1:4) in TOLE solutions and BTS
extender in a completely randomized design; treatments were replicated four
(4) times. Extended semen was stored at 170C and evaluated for semen
qualities which include pH, dead/live ratio (%) and sperm cell concentration
at time intervals (0, 12, 24, 36 and 48) hrs. Extended semen was
significantly (P < 0.05) affected by semen extenders and storage periods for
pH, and dead/live ratio (%) but sperm cell concentration (103/cm3) not (P >
0.05) affected. The pH values for BTS was significantly (P < 0.05) higher as
compared to TOLE extenders. 75% TOLE extender had highest value (43.89%),
and BTS had lowest value (12.15%) for dead/live ratio significantly (P <
0.05). The pH and dead/live ratio (%) values increased over storage time in
all extender. The optimum performance of TOLE as compared to BTS extender
was recorded at 50% concentration of TOLE extender. TOLE showed a potential
as boar semen extender, but further studies are required to validate and
improve its application.

In order to determine the effect of intensity of light and stocking density,
as well as the interaction of light intensity x stocking density on body
weight and individual carcass traits, an experiment was performed on 1200
broilers of the Ross 308 genotype. The investigated factors were the
intensity of light (LI): 20 lx (K) ; 150 lx (O) and stocking density (SD):
10 broilers/m2 (A); 13 broilers/m2 (B); 15 broilers/m2 (C), in 4
repetitions. The light source was incandescent bulbs of adequate intensity
and a light program 16L: 4D: 2L: 2D was applied. Broiler body weight was
controlled on 11th, 21st, 35th and 42nd day, by individual measurement of
all chickens in the trial. The average sample containing 12 chickens per
treatment with equal gender representation (total of 72 broilers) was used
to study the slaughter quality of carcasses based on the parameters of
absolute and relative yield of more valuable carcass parts (breast, thighs
and drumsticks) and meat in the more valuable parts of the carcass. The
effect of light with different intensity on the body weight differed
depending on the broiler rearing phase. The interaction effect of the
intensity of light and stocking density on the body weight of broilers was
confirmed in all stages of growing up to the age of 42 days. A higher
intensity of light (150 lx) showed the potential to alleviate the negative
effects of higher stocking density (15 broilers/m2) on the final body weight
of the broiler. The carcass traits were not significantly affected by the
intensity of the light, while the stocking density, as well as the intensity
of the light x stocking density did influence the yield of whole breast and
the yield of breast meat.
Milk yield prediction between Bunaji Holstein Friesian cross bred and Holstein Frisian cows using linear, cubic and quadratic models
Authors: Liman Mohammed , Sylvester Gwaza , Dogara Bala
Published: April 2018

The aim of this study was to compare three different models (Linear, cubic
and quadratic) to find best model for predicting milk yield. Data originated
from the monthly milk yields records of 251 Bunaji Holstein Friesian crossed
and Holstein Friesian cows from 2010 to 2015. The daily milk yield data were
regressed against time (day of lactation) for individual cow, using the
procedure of SAS, (2002). The resulting polynomial regression coefficients
(linear, quadratic and cubic) were then subjected to variance of analysis.
All models provided an acceptable level of accuracy in predicting milk yield
for Bunaji Holstein Friesian crossed and Holstein Friesian cows, but cubic
model is observed to be the most suitable with (R2) values of (0.659, 0.582,
0.810 and 0.621) followed by quadratic model (0.447, 0.516, 0.614 and 0.605)
while linear model has the least R2 values (0.02, 0.496, 0.548 and 0.309) in
all the study farms.

Introduction. The occurrence of peptic ulcer in patients with liver cirrhosis
is intriguing due to its frequency and complexity. The aim of the present
study was to investigate the incidence of peptic ulcer in patients with
liver cirrhosis. Results. It was found that in these patients the usual
aggressive factors of the gastric environment do not play a major role in
ulcerogenesis; however, researches noticed the importance of reduced mucosal
defense which, in portal hypertension, has the features of hypertensive
portal gastropathy. The presence of Helicobacter pylori infection in these
patients is lower, compared to other patients with peptic ulcer. The
prevalence of Helicobacter pylori infection decreases with the severity of
liver cirrhosis. Non-steroidal anti-inflammatory drugs play an important
role in peptic ulcer bleeding in cirrhotic patients, but the data are
limited and contradictory. Peptic ulcer bleeding is the most frequent
etiology of nonvariceal bleeding and it is associated with a great number of
complications. Conclusion. Helicobacter pylori infection cannot be
considered the key risk factor for the development of peptic ulcer in
patients with liver cirrhosis. The role of non-steroidal anti-inflammatory
drugs is accepted, although the data are controversial. The treatment of
peptic ulcer in cirrhotic patients is identical to the treatment of peptic
ulcer in patients without liver cirrhosis, except in cases of bleeding
ulcers. There are specific therapeutic protocols for peptic ulcer bleeding
in patients with liver cirrhosis.

Characterization of phytoplasmas associated with coconut wilt disease in Derawan Island using in silico RFLP. Coconutwilt disease has been reported in Derawan Island that resulted in eradication up to 10% of the total cultivated palms. Theobjective of this study was to detect and characterize phytoplasmas associated with coconut wilt disease in Derawan islandusing nested PCR technique and in silico RFLP based on 16S rRNA gene sequences. Detection of phytoplasmas was performedusing nested PCR method, cloning of nPCR products, sequencing, and analysis of sequencing results using in silico RFLP.The results revealed that phytoplasmas could not be detected by PCR using P1/P7 primer pairs however it could be amplifiedby nested PCR using R16F2n/R16R2 primer pairs resulting amplicon at about 1.25 kb. In silico RFLP analysis indicated thatphytoplasmas associated with coconut wilt disease in Derawan Island belong to 16SrII (witches broom phytoplasma). PCRproduct of the nPCR need to be sequenced because the R16F2n/R16R2 primer will also amplify the other bacterial species, mainly from Gram positive bacteria.

Published: April 2018

The aim of this paper was to describe the branching schema of the ventral branches of the abdominal aorta: the a. celiaca, the a. mesenterica cranialis and the a. mesenterica caudalis. The study was carried out on nine adult European hares using the corrosion cast technique. After the euthanasia, the vascular network was perfused with saline. Batson’s corrosion casting kit No. 17 was used as a casting medium. After polymerisation of the medium, the maceration was carried out in KOH solution. In all specimens, the first branch originating from the a. celiaca was the a. lienalis. The a. hepatica was present as the second branch in four cases and as the third branch also in four cases. The first branch of the a. mesenterica cranialis was the a. colica media in seven cases. The second branch was represented by the a. pancreaticoduodenalis caudalis also in seven cases. Two aa. jejunales originated as the third branch. In seven cases, the fourth branch formed the truncus jejunalis and the fifth branch the a. ileocecalis. The a. mesenterica caudalis had a uniform arrangement in all of the specimens. The results enabled us to conclude that there was higher variability of the branching pattern of the a. celiaca in comparison with the a. mesenterica cranialis and the a. mesenterica caudalis in the European hare.

Ductus deferens plays an important role in sperm transport and participates in the preservation of structure, maturation, and viability of sperm. In this study, we have immunohistochemically examined the ductus deferens in the goat. For immunohistochemical study the following monoclonal antibodies were used: cytokeratin 18, α-smooth muscle actin (α-SMA), vimentin and elastin. Morphologically, three distinct layers were identified in the goat ductus deferens — tunica mucosa, tunica muscularis and tunica adventitia. The epithelium of the mucosa was intensely stained with cytokeratin 18 (CK 18). The fibroblasts in the lamina propria and blood capillaries in the muscle layer showed positive reaction for vimentin. A positive reaction for α-SMA was observed in the smooth muscle cells of the tunica muscularis in the internal, middle and outer sublayers. An intense positive reaction for α-SMA was observed in the wall of the blood vessels. Elastic fibers in the form of a loose meshwork were present in all three layers. The high density of elastic fibers were found in the tunica adventitia.

Bacterial meningitis is a devastating worldwide disease. Half of the survivors of meningitis remain with permanent neurological sequelae. The pathogenesis of meningitis is based on a complex host-pathogen interaction. Streptococcus pneumoniae is a life-threatening neuroinvasive pathogen that asymptomatically colonizes the upper respiratory tract. Adherence of pneumococci to the host epithelium is a prerequisite in the onset of streptococcal infections; such adherence is favored by the formation of bacterial pili. In this article, we will describe the pneumococcal pili and its contribution to the onset of meningitis.

Spinal cord neurostimulation is a minimally invasive treatment method for chronic neuropathic pain that is refractory to treatment, and is part of top technology in field. Relatively recent introduction of this method in the Neurosurgery Clinic “Prof. Dr. N. Oblu” of Iasi has aligned the clinic’s therapeutic arsenal to world standards. This has made it possible to treat in Romania a category of patients who would be treated abroad until now. Our clinic has entered the “National Program for diagnostic and treatment using high performance equipment” - Subprogram of treatment of neuropathic pain by implant of a spinal cord neurostimulator and is currently the only one in Romania where this treatment can be done. This represents a new step in the transformation process of the Clinical Hospital Emergency “Prof. Dr. N. Oblu” Iasi in a real Center of Excellence in the field Neurosurgery. The team dealing with the implant consists of 3 neurosurgeons, a neurologist, pa sychologist and an anesthetist, trained in a specialized foreign center.

Published: April 2018

Introduction: Maximal surgical resection with the preservation of cortical functions is the treatment of choice for brain tumors. Achieving these objectives is especially difficult when the tumor is located in an eloquent area. Navigated transcranial magnetic stimulation (nTMS) is a modern non-invasive, preoperative method for defining motor and speech eloquent areas.

Material and methods: Patients with tumors located in motor and speech eloquent areas who presented at our institution between March 2017 and December 2017 were prospectively included. Exclusion criteria were frequent generalized epileptic seizures and cranial implants. For lesions involving motor eloquent areas we performed a nTMS motor mapping and for lesions involving speech eloquent areas we supplemented the motor mapping with speech and language mapping. MR images were exported from the nTMS system in a DICOM format and then loaded in the intraoperative neuronavigation system. Based on these findings, the optimal entry point and trajectory were determined, in order to achieve a maximum surgical resection of the lesion, while avoiding new post-operative neurological deficits.

Results: Nineteen patients underwent an nTMS brain mapping procedure between March 2017 and December 2017. In all cases a motor mapping procedure was done, but only in eight cases a speech mapping was also performed. Three patients presented new minor postoperatory deficits that consecutively remitted. The rest of the patients presented no added neurological deficits after surgery. In five cases the preexistent deficit was ameliorated after surgery and in three cases the deficit remitted. In one patient there was no improvement in the neurologic deficit after surgery.

Conclusion: nTMS is a reliable tool for the preoperative planning of eloquent area lesions. It must be taken into account that functional areas have a high individual variability. Therefore, knowing preoperatively the extent of the eloquent area helps the neurosurgeon adapt the surgical approach in order to obtain a better functional outcome.
