Capacidad para diferenciar sentimientos de sensaciones corporales y para identificar y describir sentimientos evaluados con la TAS-26 ítems
Authors: Llermanos GCI
Published: September 2024

El término alexitimia refiere a la incapacidad o dificultad para identificar las emociones propias; es considerada un rasgo dimensional  de la personalidad. Uno de los factores constituyentes de este rasgo es la incapacidad del sujeto para diferenciar sus sentimientos de sus sensaciones corporales, como así para identificar y describir sus propios sentimientos. Objetivos: describir la capacidad para diferenciar los sentimientos de las sensaciones corporales e identificar y detallar los sentimientos, en una muestra de estudiantes diferenciada por sexos.Estudio observacional, descriptivo, de diseño transversal tipo encuesta, en la modalidad de cuestionario autoadministrado, en el ciclo lectivo 2018. Selección de la muestra: muestreo aleatorio simple (n=80). Instrumento: Escala de Alexitimia de Toronto 26 ítems (TAS-26), que evalúa cuatro factores: Factor I (Diferenciar los sentimientos de las sensaciones corporales y capacidad para identificar y describir sentimientos), Factor II (Capacidad para comunicar a los demás los propios sentimientos), Factor III (Capacidad para imaginar o fantasear) y Factor IV (Tendencia a preocuparse más por problemas externos que por el análisis de experiencias personales). En esta investigación se evaluó el Factor I (rango de puntajes de 11 a 55).  En lo que respecta a la metodología estadistica para el análisis de la información se realizó la codificación y tabulación de los datos; para esto se construyeron tablas de contingencia bivariables para indicar las frecuencias absolutas, relativas, porcentajes y frecuencias acumuladas. Se estableció un error alfa al nivel de significación de una p<0,05%. Con el fin de analizar las diferencias en las distribuciones de frecuencias se utilizó la prueba del Chi Cuadrado que evalúa variables categóricas en escala nominal u ordinal.Muestra total: 7,5% puntaje menor a 20; 77,5% entre 20-40 y 15% mayor a 40. Muestra por sexos: varones 5% y mujeres 8,3% (puntajes menores a 20); varones 80% y mujeres 76,7% (puntajes entre 20 y 40); 15% en ambos sexo (puntajes superiores a 40). Sin diferencias estadísticamente significativas para cada una de las categorías de puntajes. En la muestra total prevalecieron los puntajes de 20 a 40. El sexo no influenció los puntajes del Factor I.
Evaluación morfológica de las uniones intercelulares en ovario del embrión de pollo: acción de hormonas esteroideas y gonadotróficas IN VITRO
Authors: Ávila Rodolfo , Samar María Elena , Parisi de Fabro Sofía
Published: September 2024

Variations of the intercellular junctions of the germ and epithelial cells of the ovarian epitheliurn produced by gonadotropic and esteroid hormones were determined on ovaries of the chick embryo at 7 days of development.Explants of right and left ovaries were cultured without (control) or with hormones eddition (experimental) for 4 days. Cultures wereprocessed for their ultrastructural study. In both control ovaries the union complexes were similar to those identified in ovo. Under the action of 17 f3-estradiol, an increase and a greater development of adherens junctions vas observed in the left ovary; in the rightovary, adherensjunctions diminished by actionof 17 l3-estradiol. The response of the left ovary to progesterone and testosterone was similar to that seen with the estrogen. No changes were observed in the right gonad. A disminution of intercellularjunctions Nvas produced in both ovaries under the action of FSH. The changes produced by LH and hCG were similar to those find in the left ovary with the estrogen, consisting of an increase of the union complexes, mainly of the adherens type. These results indicate that steroid and gonadotropic hormones act by modifying intercellular junctions and would participate in the processes of growth and atrophy that occur in the ovaries of the chick embryo.

En el marco de as acciones humanas, el Hombre es creador de su propia Historia.De allí dimana la importancia de Los Museos, que sin lugar a dudas, son casi, los más antiguos monumentos de la Humanidad.Todo Museo es un medio de comunicación entre el hombre y su pasado. Por eso, se establece un diálogo imaginario entre el observador y el objeto observado, estableciéndos una riquísima trama de razonamiento e imaginación.Razonamiento, porque el observador nose puede sustraer a preguntas y respuestas, que él mismo trata de responder mas allá de la fría referencia de una fecha, un lugar o un nombre.Imaginación, que va unida siempre frente a todo testimonio del pasado. Por acción de ambas, razonamiento e imaginación, la se-milla del saber quedará germinando en el fértil campo del conocimiento.El DIA INTERNACIONAL DE LOSMUSEOS, es el 18 de Mayo, siendo cada año una fecha importante para la museología delmundo entero. La celebración destaca el lugar relevante de estos lugares que congregan objetos diversos relacionados con la cultura de cada pueblo; documentos históricos y obras de arte que incrementan el patrimonio de una provincia o nación.En el año 1977, la fecha fue establecida por la Asamblea General del Consejo que nuclea a todos los Museos del mundo (I.C.O.M), reunida en Moscú para tal efecto.La Universidad Nacional de Córdoba, conciente de que los Museos tienen como principal objetivo, preservar, investigar y educar,convirtiéndose en lugares de vital importancia para la conservación del acervo cultural e histórico de la comunidad, creó por Resol. N°152 198 (H.C.S), la RED DE MUSEOS UNIVERSITARIOS.Dicha RED, une a los Museos de las distintas Facultades, a saber: cinco Museos dependientes de la Facultad de Ciencias Exactas, Físicas y Naturales; uno de la Facultad de Filosofía y Humanidades; seis Museos de la Facultad de Ciencias Médicas. Se agregan además dentro de la RED, las Colecciones pertenecientes al Colegio Nacional de Monserrat y la del Observatorio Astronómico. Sumándose por su interés también, la Pinacoteca de la Escuela de Arte.Nos referiremos en el presente trabajo, a los Museos dependientes de la Facultad de Ciencias Médicas, los que insertos en la vida de la comunidad universitaria, constituyen un notable beneficio para los alumnos, investigadores y docentes.
Comportamiento ultraestructural de la inervación de las células intersticiales durante la diferenciación del ovario del embrión de pollo cultivado con 17- 8- ESTRADIOL
Authors: Ávila Rodolfo , Sammar MARÍA , Ferraris Ricardo , Bonomi Lucía
Published: September 2024

In a previous work we demonstrated the relationship between nerve fibers and nerve endings and interstitial cells (estrogen producing cells) from the atrophic right ovary and the medulla in the left functioning ovary during embryogenesis in the chick, ¡u ovo. Besides, the local production of neurotrophins by steroidogenic cells is probably involved in the control of ovarian innervation. The objective of the present study was to analyze ultrastructurally the innervation during the diffcrentiation of chick ovary cultured with 17- 13 -estradiol. Explants of right and teft ovaries from seven to nineteen days in ovo development were cultured separately for 4 days in MEM (controls) or in the presence of 17- II -estradiol (problems).
In controls the electron microscopic examination of the innervation explants from chick cmbryo ovaries revealed that the interstitial cells are well innervated. Nerve fibres and nervecndings were observed in close contact with steroid-producing cells, a similar pattern of innervation that those of the fifteen days ovaries inovo det'elopinent. Problems cultured from seven days showed nerve fibres and nerve endings at difference to controls. These results ¡o vitro suggest that innervation of the ovaries is controled by indirect mechanism via the hypothalamic-pituitary system and local production factors. More experiments are necessary to confirm this results.

Published: September 2024

The necessity to maintain the nutritional integrity in patients subjected to major surgery of the superior digestive tract has been broadly accepted. The enteral nutrition for yeyunostorny is accepted as more physiologic, sure and effective than the parenteral one. Materials ami Method: 171 yeyunostomies were indicated in: 151 patients with rnahignant neoplasm of the superior digestivelract, 15 with infected pancreatíc necrosis, 3 hi le-duodenum-pancreatic traumatisms and in 1 stenosis for gastroesophagic reflux.Depending on the pathological type, a yeyunostorny using the Witzell technique was carried out with either local or generalanesthesia ata 15 to 20 cm. of the Treitz angle. To facihitate the fixation of the catheter and to avoid the stenosis of the jejunum we have incorporated, as an original technical detail, the proximal serous section with cold scalpel in about 4 cm, that is to say in the sector to be tunneled. Results: There was not mortality in relation to the yeyunostomy. Among the minor complications we crnphasize the abdominal distension, cohic pain and diarrhea, situations that were reverted, controlling the debit and the feedi ng characteri sties. This approach could be maintained for period of 2 months and in sorne cases at home.Conclusions: Wc emphasize the great importance of the enteral feeding for yeyunostomy, for its of easy handling, securityand low cost that, together with the suggested technical detail, has allowed us to obtain a deeding road almost without inherentcomplications.

Published: September 2024

The purpose of this work was to obtain new data on factors intervening in the production and progression of human chagasiccardiopathy (HChC) with death by cardiac failure. Wc siudied cardiac samples ofpatients that died at an early mean age versus others that died at older ages. The infiltrating ce [1s were characterized and cluantified by means of specific monoclonal antibodies and inmunohisto- chemical methodology; and by classical histological and histochemical methods. We found intense cardiac infiltration by lymphocytes that reacted with the antibodies anti-CD45RO against activated T- lymphocytes (<70%). A similar number showed reactivity for C134. And, in seriate sections, showed PAS+ substances in their cytoplasms.Macrophages were detected in a number of 25%. Few lymphocytes reacted to C138. There was a low number of B lymphocytes. Other noticeable infiltrated eclI were intramiocardial mast cells. Qualitatively, such findings were similar in the two groups of patients. However, the number of T-lymphocytes and of the mast celis was significatively higher in the cases that underwent early cardiac death (p< 0.001). .1 cruzi was not found. In cardiomyocytes, damages were found, with T-lymphocytes and macrophages adhered to their sarcolemma, as weU as mast cells. CONCLUSIONS These findings suggest the existence of an active and intenseoccurrence of immunocellular mechanims in the production and evolution of severe HChC, in which T-lymphocytes CD4+ intervene, with production and secretion of PAS+ substances; Besides, macrophages, and mast cells, in that order. The quantity of infiltrated cells was positively associated with the occurrence of malignant arrithrnyas. We suggest that such facts would be involved in the poor cardiac perfomance of the chagasic heart disease that leads to cardiac death. Indeed, they seem be worthy of consideration with respect to therapeutic strategies.

From the first description of Pretl in 1944, many authors have shown difterent morphological and immunohistochemical studies related to prostatic neuroendocrine cells. These cells belong to a neuroendocrine system, wide disseminated network, that is found in man)' human tissues. They secret neuroendocrine peptides and play an important role in the glandular pithelium regulation (growing, differentiation, and exocrine secretion), in both normal and hyperplastic glands. They are also present in ordinary prostatic adenocarcinoma and in unusual small ccli carcinoma. Recently, it has been suggested that prostatic neuroendocrine celis may be relatedto prognosis in prostatic carcinoma, particulary in cases with hormonal therapy resistant. In this study, there are 23 prostatic disorders: 11 nodular hyperpiasias and 12 adenocarcinomas, and also arcas of normal gland.The objetive is the morphologic identification of these cells with sil ver impregnation technique, in normal tissuc, nodular hyperplasia and adenocarcinorna. In normal gland and nodular hyperpiasia, the NE cells can he seen along most of the gland or near the urcthra, solitary or in small clusters. These cells are located hetween acinar epithelium cells and basement membrane, but they are a]so found within the stroma in relationto nerve endings. They characteristically contain argyrophil and argentaffin granules in the cytoplasm and exhibit cytoplasmatic processes extended to acinar or urethral lumen. Within the stroma, they are seen isolated with dendritic or ribbon-like cytoplasmaticprocesses. In this study, there is only one adenocarcinoma of high grade with NE cells. In this neoplasm they are increase in number, and appear isolated and more polymorphic

The success of cornea transplantationshas always been a concern of world researchers to identify risk factors from the proper surgicaltechniques up to the severa] tissue storage procedures, such as the ones used in the new laboratories called eyes banks. However, the integral research works are still limited at present and they continue putting emphasis in the donor cornea storage that guarantee up tofor this tissue feasibility. This research had the aim to contributeto the improvement of the corneal tissue quality taking into account the maintenance of its na- tural curvature and tensions combining themwith sorne standard preservation solutions. This was achieved by rneans of a new mechanical system. Assays with rabbits were designed according to a sequential experimental groups design. In these ones, the study of the feasibility parameters behavior under different conservation media, related to the time, was splitted into four blocks. The first and second ones attended the cornea conservation in the short and intermediate-terms culture mediums as the ones at 40C degree isolated cornea preservation and the usual ones such as the Me Carey Kaufman, Optisol and Likorol solutions used in the eyes banks. The third nne was designed for the surgical assays comino from the two named groups and the last one focused the time study of these parameters for a new conservation technique, developed as an alternative medium to keep the cornea tissue curvatures and tensions as well as its nutrition and hydration.The results showed that tissue natural tensions maintenance is an significant factor in the conservation process, which involve the cornea feasibility for the its use in future transplantations. Since the new developed technique is very simple, this study is considered to be a significant contribution for the stoiage and biological material handling steps.

Among the diverse complications ofthyroidectomy, it is mostly the cordal sequels from the recurrent laryngeal nerve damage. This is why anatomical and surgical considerations are made upon the vulnerable areas of this nerve and the circunstances inwhich it is damaged. The relationship between the recurrent laryngeal nerve and the inferior thyroid artery, location most frequently injured, wasinvestigated on 55 adult formolated cadavers. It was found that on the right side in 54.5 % the nerve passes behind the artery, in 38.1 % it passes in front of it, and between its terminal branches in 7.2%.Regarding the left side, in 67.2 % the nerve passes behind (he artery, in 27.2 % it does so in front of it, and in 5.4 % between its terminal branches; being the right nerve more anterior an lateral ;han the left one which would possibly explain the higher index of nervous damage on this side.

Lipids are important ceil components, both from the structural and the functional point of view. Besides they intervein in transportingfunctions, cell recognition and immunity. Essential Fatty Acids (EFA) are important for the functional and structural maintenance ofanimal organisms. In our laboratory, it was demonstrated that one group of pregnant rats fed on an EFA deficient diet, and other group of rats fed onthe same diet but with 5% of corn oil (rich in linoleic acid) showed alterations on the development of the metrial gland. In the present work, 57 female rats of a Wistar strain were fed since weaning with one of the followingdiets : EFAD :deficient in essential fatty acids, COD: EFAD + 5% corn oil (linoleic acid sufficient but (x- linoleic acid deficient); SAD: EFAD + 5% soy oil (both EFA sufficient) and CD: commercial diet. After 3 months theanimals were sacrificed on the 13 th. day ofgestation.Uteru's horns were dissected and the irnplantation sities were fixed on formo] and embebbed in parafine. The observations were carried out with RÍE coloured cross-sectionsand the corialantoidea placenta, the sities of implanctations and the sitios of reabsortions were studied. The metrial gland of DAGE andDAM rats presented structural modifications compared to DC rats. The most relevant findings were: indifferentiation of thegranulated metrial gland celis and an increase in the amount of connective tissue.

DEJ is regarded as a highlv specialized basal lamina. which acts as a highly selective pathway for the migration of celis and macroniolecules, inducing cellular differentiation and micro envirornental metabolism modifications. DEJ may be divided into three zones regarding the basal lamina 1 -the nearest to epiderniic zone, having tonofilaments and hernidcsmosomes, which keep anchored basal cells. This region is limited by the lamina densa 2 -the intermecliate zonc, represented exelusively by lamina densa and finaily the lamina 3,-the third region - extencis from lamina densa to the upper dermis ant] extracelullar matrix. Despite there is much to learn about DEJ, the knowledgc about each molecule and function of every compartment vill enable us to know more about the pathogenesis of several dermatologic diseases, with a great prevalence in Wc clinical practice.

Maternal mortality is a portrait not only related to maternal health and to the characteristic of the medical services, butalso to the social, cultural and political conditions of a given societ. It occurs 120 bubas pregnancy every year ami almost 600.000 women die because of causes related to pregnancy, delivery or puerperal diseases, 95% of those deaths occur jo unclerdeveloped countries. In Swiss, Finland, Canada and Holland, 4 deaths are registered, while in Somalia and Nigeria 1000 death are reportcd for cach 100.000 alive new baby (Ny), Meanwhile, lo Latín Arnerica and the Caribe. 190 death are reporten, alniost 23.000 women death every year, which clearly shows a great difference between countries. These differences also occur within a given country, as in Argentina. where the prevalence is 44 for each 100.000 Ny, Buenos Aires has 9 while Formosa as 177.Wc pointed out that nonqualified medical services is a very irnportant fact on the aboye mentioned maternal death, because of the lack of attention of the sepsis, the hemorrahages, the prolonged delivery work and the eclampsia. But abortion is the most irnportant cause of maternal death. We mentioned the social, educational and sanitary facts of ¡Ilegal abortion. la developed countries pre eclampsia is the main factor.

Over the years, the treatment of breast cancer has changed dramatically. We briefly  describe those changes and also the different therapeutic approches to the axillary nodes. Over the last century, the primary goal was to avoid radical surgery of the breast.  However, during the last decades, the interest was mainly focused on the possibility of  treating the axila jo a conservative way, in an effort to minimize the adverse effects of linfadenectomy. The sentinel node technique is of key importance, because nowadays it is possible to diagnose breast cancer at early stages when most of the times the axila is  negative. The early diagnoses of breast cancer makes the sentinel node technique a relevant  tool at the time of making therapeutic decisions. Wc believe that the sentinel node technique could predict in many cases the lymph node status without the need of a  complete axillary dissection of the axila in patients with breast cancer.

Sexual and Reproductive Health are considered at present as a Human Right that must be  guaranteed by the State. In Argentina sorne Federal, Provincial and Municipal Laws have  been sanctioned in order to guarantee this right through programs that bring information, counselling and implementation in the use of contraceptive methods, prevention diagnosis  and treatrnent of sexually transmitted infections and genitomammary pathologies. Many  institutions, including Universidad Nacional de Córdoba, have been incorporated in these  programs. Contraceptive methods have selection entena and indication for its use that are described in this publication, for the purpose to explain inclications, side-effects, advantages and disadvantages of each one of thern; as well as their best usefulness in the  three stages of reproductive life: adolescence, sexual matunity and premenopause. Finally,  the Eligibility Criteria were synthetized for the use of contraceptive methods, performed by the OMS in 1996.

Authors: Yorio Marcelo , Escudero Millan Andrés , Camera Luis
Published: September 2024

Infective endocarditis (IE) is still a disease with high morbidity and mortality. Its diagnosis and treatment are still a major challenge in clinical practice. There have been very few studies published about IE in Argentina. Methods: We reviewed all the studies about IE published in the Argentine Medicine Society from 1980 to 2003 and we analyzed demographic, clinical and bacteriological data. Results: 27 studies with 628 patients were included. Mean age of patients was 50.7 years old. The most frequent clinical data were fever, murmur and elevated sedimentation rate. Stafilococcus spp was the most common causative organism, followed by streptococcus spp. The echocardiographic demostration allowed the definitive diagnosis in 2/3 of the patients. Conclusion: The IE data of Argentina are not different from other data published in different countries and this study shows some clinical features of IE in Argentina.

Published: September 2024

Wegener´s granulomatosis is a granulomatous necrotizing vasculitis which predominantly affects the respiratory tract, kidney, and less frequently other organs such as the nervous system. The latter may occur in up to 54% of cases and when it does it is more frequently of the peripheral nerves. We present a 19 year old woman who commenced her disease with involvement of respiratory sinuses, lungs and kidney and who developed central insipid diabetes (CID) at onset. The CID persisted in spite of adequate response of the other organs and systems with immunosuppresor treatment. The development of CID in the context of vasculitis should suggest this as a possible mechanism.

Published: September 2024

Calcium is essential for bone and tooth formation, achievement of optimal peak bone mass and also for regulation of physiological processes. The calcium demand depends on age, gender and different physiological processes. These requirements are higher during childhood, pregnancy and lactation. Dietary Ca2+ deficiency modifies Ca2+ homeostasis and the metabolism of calciotropic hormones and increases the efficiency of intestinal Ca2+ absorption and renal reabsorption, altering bone metabolism. The low Ca2+ diet is associated with hypertension and risk of cancer.
Uso de la técnica de hibridación fluorescente in situ para la identificación rápida de staphylococcus aureus en hemocultivos
Authors: Cómito Maria L. , Vilaró Mario , Cuestas Eduardo , Moscone Eduardo
Published: September 2024

Background: The technique of reference for the detection of bacteriemia is the blood culture. One of the most frequent bacteria responsible of bacteriemia is Staphylococcus aureus (SAU). The presence of Gram positive cocci (CGPR), in blood culture give the suspicious of bacteriemia, although the relevance of the finding depends on the correct identification of the microorganism. The definitive typification it demands from 24 to 48 hours. The technique of fluorescent in situ hybridization (FISH), is a rapid method for the identification of bacteria in blood culture. Aims: The aims of this work was to establish the FISH technique directed to the 16S RNA of SAU in samples of blood cultures with CGPR to the Gram staining, to determine the concordance with the method of reference, and to evaluate the possibility to use as standard method in the laboratory of microbiology. Material and Methods: The blood cultures analyzed in the Laboratory of Microbiology of the Hospital Privado Cordoba from 01.01.2009 to 31.12.09 were included in this study. To each positive blood culture which showed CGPR was applied simultaneously biochemical identification and FISH. Results: From 496 positive samples, 32 showed CGPR, 24 of them were identified as SAU. A concordance of 100% (IC95% 99 to 100) between both methods of diagnosis, with a value of k<0.01 was observed. Discussion: The excellent concordance opens the prospect for a study in order to determine the predictive value of FISH, its sensibility and specificity. Furthermore, it will be possible to evaluate its clinical impact being incorporated in a laboratory of clinical bacteriology.
