Resumen Introducción: En Chile, las enfermeras/os tienen respaldo legal para gestionar el cuidado, esto facilita el desarrollo de competencias para ejercer autonomía y liderazgo. Actualmente persisten barreras para transitar hacia un reconocimiento real de la independencia profesional. Objetivo: Develar la experiencia vivida de enfermeras con cargos en niveles de jefatura respecto al propio desarrollo para lograr el liderazgo y autonomía profesional. Metodología: Estudio cualitativo, descriptivo-interpretativo, desde la trayectoria fenomenológica de Edmund Husserl. Muestreo selectivo de caso homogéneo de tres enfermeras que desempeñaban rol de jefatura en instituciones de salud, región Valparaíso, Chile. Participación consentida. Entrevista no estructurada. Análisis del discurso utilizando el modelo de liderazgo integral de Ken Wilber. Resultados: Categorías: Conciencia del líder «ser inquieta...intelectualmente¼. Construyendo competencias «el liderazgo se aprende¼. Transitando hacia el ejercicio de la autonomía y el liderazgo, "para el posicionamiento hay que luchar". El peso de las estructuras organizacionales «tu rol es parte de un hospital¼. Interpretación: El ejercicio del liderazgo y la autonomía se fundamenta en competencias actitudinales por sobre las cognitivas y técnicas. Existe mayor apoyo y reconocimiento a nivel institucional, que al interior del equipo de salud. Persisten limitaciones para lograr máxima expresión del liderazgo y autonomía, por persistencia de modelos institucionales hegemónicos, centrados en decisiones médicas y desconocimiento del rol integrado. Conclusión: El líder se mueve en un escenario dual, entre un menor reconocimiento del equipo y un creciente empoderamiento del rol autónomo y visibilidad a nivel directivo institucional.

Abstract Introduction: In Chile, nurses have legal support to manage care, a situation which facilitates the development of competencies to perform with autonomy and leadership; however, barriers still persist while moving towards a real acknowledgement of professional independency. Objective: To unveil the lived experience of nurses in executive roles regarding their own development towards leadership and professional autonomy. Methodology: This is a descriptive and interpretative qualitative study framed by the Edmund Husserl phenomenological approach. The sample by homogeneous case included three nurses in executive roles in health institutions in Valparaiso, Chile. The participation was by consent. An unstructured interview was used. For the discourse analysis, the Ken Wilber integral leadership model was followed. Results: Categories: Leadership awareness <being inquiring… intellectually>… Building Competencies <leadership is learned>. Moving towards the practice of autonomy and leadership, "positioning requires striving". Weight of the organizational structures <your role is part of a hospital>. Interpretation: A practice of leadership and autonomy is based on attitude competencies over the cognitive and technical ones. Nevertheless, there still persist limitations to achieve a maximal expression of leadership and autonomy due to hegemonic institutional models which focus on medical decisions and neglect the integrated roles. Conclusion: The leader moves in a dual setting between a lower acknowledgement from the team, and a higher empowerment of the autonomous role and the visibility at the institutional directive level.

Anterior chamber associated immune deviation to cytosolic neural antigens avoids self-reactivity after optic nerve injury and polarizes the retinal environment to an anti-inflammatory profile.

It has been hypothesized that anterior chamber-associated immune deviation (ACAID) to neural antigens induced prior to central nervous system injury can inhibit self-reactivity and lessen secondary degeneration. This work evaluated the effect of ACAID induced to three neural tissue-derived extracts (whole extract, cytosolic extract, CE; or organelle-membrane extract) prior to optic nerve injury on retinal ganglion cell (RGC) survival. The results show that only ACAID to the CE increased RGC survival at 7 and14 days post-injury (dpi). This effect was achieved by retinal polarization towards an anti-inflammatory profile, driven by regulatory T cells and M2-type macrophages at 7 dpi.

Helminth community from Azara's grass mouse (Akodon azarae) in three habitats with different land use in farming systems of Argentina.

In the Pampa region of Argentina, farming activities have been performed since the beginning of the 20th century, but in the 1990s, land-use patterns rapidly changed towards intensive agriculture and poultry breeding. This study compares the helminth community of Akodon azarae (Rodentia) among three habitats with different land use in pampean agroecosystems: poultry farms, mono-cultivated fields and abandoned fields (not used for 35 years), under the prediction that there will be greater helminth richness and diversity in mice from abandoned fields compared to those from the other habitats. Nevertheless, the highest abundance of A. azarae occurred on poultry farms, the habitat most disturbed by human activity, while cultivated fields showed the lowest. Helminth richness and diversity were significantly higher on poultry farms than in the other habitats, due to the presence of Trichuris laevitestis, Protospirura numidica criceticola and cysts of Taenia taeniaeformis. We suggest that the helminth fauna of A. azarae can survive on poultry farms despite disturbance from farming activities, because rodents can move and get shelter within farm perimeter fences, where dense and high vegetation grows. This farm area could offer good conditions for geohelminth development, while chicken sheds could attract insects that are intermediate hosts of helminths with indirect life cycles. On the contrary, agrochemicals applied in cultivated fields would negatively influence helminth diversity and composition, by decreasing host populations (arthropods and rodents) and affecting free larval stages of geohelminths.

Preoperative serum albumin as a predictor of complications following total hip replacement in patients with rheumatoid arthritis / Albúmina sérica preoperatoria como un predictor de complicaciones posterior al reemplazo total de cadera en pacientes con artritis reumatoide

Abstract: Background: Rheumatoid arthritis is a chronic inflammatory disease characterized by polyarthritis with progressive articular wear, immunologic abnormalities and increasing physical limitation. Surgical correction with hip replacement comes as a successful solution for patients with advanced articular destruction. Following intervention, surgical site infection (SSI), venous thromboembolism, sepsis, renal and major cardiovascular complications are among the most cited in the literature. No consensus exists as to the detection of preoperative hypoalbuminemia in patients with rheumatoid arthritis. Methods: This study retrospectively evaluated the preoperative serum albumin of 75 patients with rheumatoid arthritis and analyzed its relevance in terms of appearance of postoperative complications with a six-month follow-up. Complications in the group of patients with low serum albumin and the group of patients with normal serum albumin were reviewed to identify the effect of each variable. Odds ratio for each variable was calculated (hospital readmission, surgical site infection, renal and cardiac complications, non-infectious wound complications and the presence of residual hip pain), as well as p-value and confidence intervals. Results: Surgical site infection showed a statistically significant relation with low serum albumin (OR: 6.125, p = 0.018) as did non-infectious wound complications (OR: 3.714, p = 0.026) and residual hip pain (OR: 3.149, p = 0.022). Conclusion: Preoperative low serum albumin has a direct relation with the rate of postoperative complications including SSI, non-infectious wound complications (seroma formation, wound dehiscence) and residual hip pain. Preoperative serum albumin is a reliable marker of nutrition, which may establish preventive strategies to reduce postoperative complications in patients with rheumatoid arthritis.

Resumen: Introducción: La artritis reumatoide es una enfermedad inflamatoria crónica con desgaste articular progresivo, anomalías inmunológicas y aumento de la limitación física. La corrección quirúrgica con el reemplazo de la cadera es una solución a la destrucción articular avanzada. Después de la intervención, la infección del sitio quirúrgico (SSI), el tromboembolismo venoso, la sepsis y las complicaciones cardiovasculares o renales se encuentran entre las más citadas en la literatura. No existe consenso en cuanto a la detección de hipoalbuminemia preoperatoria en pacientes con artritis reumatoide. Métodos: Estudio retrospectivo evaluando la albúmina de suero preoperatoria de 75 pacientes con artritis reumatoide, se analizó su importancia en términos de complicaciones postoperatorias en los primeros seis meses de seguimiento. Las complicaciones en el grupo de pacientes con albúmina de suero baja y el grupo de pacientes con albúmina de suero normal fueron repasadas para identificar el efecto de cada variable. Se calculó el odds ratio para cada variable (reingreso hospitalario, infección del sitio quirúrgico, complicaciones renales y cardíacas, complicaciones no infecciosas de la herida y presencia de dolor de cadera residual), así como el valor p y los intervalos de confianza. Resultados: La infección del sitio quirúrgico demostró una relación estadística significativa con la albúmina de suero baja (o: 6.125, p = 0.018) al igual que complicaciones no infecciosas de la herida (o: 3.714, p = 0.026) y dolor residual de la cadera (o: 3.149, p = 0.022). Conclusión: La albúmina sérica baja preoperatoria tiene una relación directa con la tasa de complicaciones postoperatorias: infección, formación de seromas, dehiscencia de la herida y dolor residual.

Supplementing sow diets with palm oil during late gestation and lactation: effects on milk production, sow hormonal profiles and growth and development of her offspring.

The supplementing of sow diets with lipids during pregnancy and lactation has been shown to reduce sow condition loss and improve piglet performance. The aim of this study was to determine the effects of supplemental palm oil (PO) on sow performance, plasma metabolites and hormones, milk profiles and pre-weaning piglet development. A commercial sow ration (C) or an experimental diet supplemented with 10% extra energy in the form of PO, were provided from day 90 of gestation until weaning (24 to 28 days postpartum) in two groups of eight multiparous sows. Gestation length of PO sows increased by 1 day (P<0.05). Maternal BW changes were similar throughout the trial, but loss of backfat during lactation was reduced in PO animals (C: -3.6±0.8 mm; PO: -0.1±0.8 mm; P<0.01). Milk fat was increased by PO supplementation (C day 3: 8.0±0.3% fat; PO day 3: 9.1±0.3% fat; C day 7: 7.8±0.5% fat; PO day 7: 9.9±0.5% fat; P<0.05) and hence milk energy yield of PO sows was also elevated (P<0.05). The proportion of saturated fatty acids was greater in colostrum from PO sows (C: 29.19±0.31 g/100 g of fat; PO: 30.77±0.36 g/100 g of fat; P<0.01). Blood samples taken on 105 days of gestation, within 24 h of farrowing, day 7 of lactation and at weaning (28±3 days post-farrowing) showed there were no differences in plasma concentrations of triacylglycerol, non-esterified fatty acids, insulin or IGF-1 throughout the trial. However, circulating plasma concentrations of both glucose and leptin were elevated during lactation in PO sows (P<0.05 and P<0.005, respectively) and thyroxine was greater at weaning in PO sows (P<0.05). Piglet weight and body composition were similar at birth, as were piglet growth rates throughout the pre-weaning period. A period of 7 days after birth, C piglets contained more body fat, as indicated by their lower fat-free mass per kg (C: 66.4±0.8 arbitrary units/kg; PO: 69.7±0.8 arbitrary unit/kg; P<0.01), but by day 14 of life this situation was reversed (C: 65.8±0.6 arbitrary units/kg; PO: 63.6±0.6 arbitrary units/kg; P<0.05). Following weaning, PO sows exhibited an increased ratio of male to female offspring at their subsequent farrowing (C: 1.0±0.3; PO: 2.2±0.2; P<0.05). We conclude that supplementation of sow diets with PO during late gestation and lactation appears to increase sow milk fat content and hence energy supply to piglets. Furthermore, elevated glucose concentrations in the sow during lactation may be suggestive of impaired glucose homoeostasis.

Acral Metastasis of the Fingers: Report of 2 Cases. / Metástasis digital acral: presentación de 2casos clínicos.

Cutaneous metastases appear in 0.6% to 10.4% of malignant tumors and account for 2% of all cutaneous tumors. Metastasis to the skin may arise from progression of a known primary tumor or provide the first sign of an unsuspected one. Acral metastases are particularly unusual. Most derive from bone tumors. Clinical signs vary and the lesions generally resemble infection or inflammation, leading to diagnostic delays. When metástasis involves the fingers, the primary tumor is usually lung carcinoma. In contrast, toe involvement usually derives from a tumor in the genitourinary tract. A pathologic diagnosis in these cases is necessary and will suggest the location of the primary tumor. We report 2 cases of metástasis to the fingers. One is the first report of acral metástasis of a myoepithelial carcinoma of the breast. The other concerns acral metástasis as the first sign of lung carcinoma.

Factors of the epidemiological triad that influence the persistence of human papilloma virus infection in women with systemic lupus erythematosus.

We studied the epidemiologic triad-related factors influencing human papilloma virus (HPV) persistence in Mexican women with systemic lupus erythematosus (SLE). Patients aged ≥18 years with SLE (American College of Rheumatology criteria), with and without HPV persistence, were selected. Groups were analyzed by (1) host: clinical disease characteristics; (2) agent: (I) infectious (prevalence, incidence, HPV genotype and co-infections (≥2 HPV genotypes or mycoplasmas)), (II) chemical (contraceptives and immunosuppressive drugs) and (III) physical (vitamin D deficiency) and (3) environment. A total of 121 SLE patients were selected over a two-year period. (1) Host: mean age 45.8 years and disease duration 12.7 years. (2) Agent: (I) infectious. HPV infection prevalence in the second sample was 26.4%, high-risk HPV genotypes 21.5% and co-infections 7.4%. HPV infection incidence was 13.2%, persistence 13.2% and clearance 15.7%. (II) Chemical: use of oral hormonal contraceptives 5% and immunosuppressive treatment 97.5%. (III) Physical: Vitamin D levels were similar in both groups. (3) Environment: (I) natural. A total of 60.6% of patients were residents of Puebla City. (II) Social: The mean education level was 10.9. Poverty levels were: III degree 52.4%, IV degree 28% and II degree 17%. (III) Cultural behavioral: Onset of sexual life was 20.5 years, 10% had ≥3 sexual partners and 51.2% were postmenopausal. In conclusion, no factor of the epidemiologic triad was associated with HPV infection prevalence.

Systematic review of kidney transplantation functional predictors. / Revisión sistemática de los métodos predictores de la funcionalidad del trasplante renal.

CONTEXT: Kidney transplantation from donors with expanded criteria has increased the pool of kidneys at the cost of a higher risk of short and long-term graft dysfunction. The main issue lies in determining which kidneys will offer acceptable function and survival compared with the risk represented by surgery and subsequent immunosuppression. OBJECTIVE: The objective of our article is to review the current evidence on the tools for predicting the functionality of kidney transplantation from cadaveric donors with expanded criteria and determining the validity for their use in standard practice. ACQUISITION OF EVIDENCE: We conducted a systematic literature review according to the PRISM criteria, through Medline (http://www.ncbi.nlm.nih.gov) and using the keywords (in isolation or in conjunction) "cadaveric renal transplantation; kidney graft function appraisal, graft function predictors". We selected prospective and retrospective series and review articles. A total of 375 articles were analysed, 39 of which were ultimately selected for review. SUMMARY OF THE EVIDENCE: The predictors of functionality include the following: The donor risk indices; the calculation of the renal functional weight or the assessment of the nephronic mass; the measurement of vascular resistances during perfusion in hypothermia; the measurement of the donor's biomarkers in urine and in the perfusion liquid; the measurement of functional and reperfusion parameters in normothermia; and the measurement of morphological parameters (microscopic and macroscopic) of the target organ. In this article, we present an explanatory summary of each of these parameters, as well as their most recent evidence on this issue. DISCUSSION: None of the reviewed parameters in isolation could reliably predict renal function and graft survival. There is a significant void in terms of the macroscopic assessment of kidney transplantation. CONCLUSIONS: We need to continue developing predictors of renal functionality to accurately define the distribution of each currently available donor kidney.

EM proves invaluable in the confirmation of chordoma in the sacral mass of a middle-aged man.

A case of a 47-year-old male with a sacral spine mass was investigated by histology, immunohistochemistry (IHC), and electron microscopy (EM). The light microscopy of the first core biopsy revealed scant cellularity with spindle and round cells with eosinophilic cytoplasm within a fibromyxoid background. Immunostaining with pancytokeratin, cytokeratin 19, and S100 was nonspecific. Another biopsy was attempted to obtain a more definitive diagnosis. Light microscopy of the second core had scant cellular material. However, the tissue was specifically requested for ultrastructural evaluation and revealed features diagnostic of chordoma. After definitive diagnosis, radical resection of the mass was performed. This case illustrates how EM was instrumental in the definitive diagnosis before radical resection in a case that was not clear by hematoxylin and eosin (H&E) and IHC alone.

Estudio comparativo de cierre de cuero cabelludo en neurocirugías supratentoriales: intradérmica vs. surget / Comparative study of scalp closure in supratentorial neurosurgery: intradermal vs. surget

Introducción: El cierre de cuero cabelludo en neurocirugías supratentoriales mediante sutura intradérmica es una técnica poco difundida en la actualidad. En contraste, es común que se efectúen suturas de alta tensión con el fin de evitar dehiscencias, fístula de líquido cefalorraquídeo (LCR) y sangrado durante el período posquirúrgico, pero que no tienen buen resultado estético. Objetivo: Comparar las complicaciones relacionadas al cierre de cuero cabelludo que se presentaron en neurocirugías supratentoriales en un período de 19 meses, para determinar si utilizar un cierre de menor tensión y con mejor resultado estético, es igual de seguro que las técnicas de cierre habituales. Materiales y Métodos: Se incluyeron 84 casos de neurocirugías supratentoriales electivas. En 43 casos (control) se realizó el cierre mediante sutura continua tipo surget y en 41 casos (experimental) el cierre fue mediante sutura intradérmica. Resultados: Se presentaron 2 casos de infecciones, 1 en cada grupo (p= 0,97) y 1 caso de sangrado en el grupo control (p= 0,32). No se presentaron dehiscencias ni casos de fístula de LCR. Conclusiones: El cierre de cuero cabelludo mediante sutura intradérmica fue un método seguro que no generó una mayor incidencia de complicaciones y logró un mejor resultado estético a corto y largo plazo.

Background: Scalp closure by means of intradermal suture in patients who underwent supratentorial neurosurgeries is currently an uncommon technique. In contrast, it is usual to perform high tension sutures to avoid skin dehiscence, cerebrospinal fluid leak (CSF) and postoperative bleeding; however it usually results in unsatisfactory aesthetic results. Aim: Comparing complications, over a two year period, related to scalp closure occurred in supratentorial neurosurgeries. The goal is to establish if the intradermal suture is as safe as the current high tension closure technique.Materials and Methods: Eighty-four patients were included. In forty-three cases (control) continuous high tension suture (surget) was performed. The other forty-one cases (experimental) underwent intradermal suture. Results: Two infection cases occurred, one from each group (p= 0, 97). There was one case of bleeding that took place in the control group (p= 0,32). Neither dehiscence nor CSF leak occurred in any of the trial cases.Conclusions: Intradermal suture performed for scalp closure was as safe as surget in terms of complications occurrence and obtained better cosmetic results in the short and long term.

Fluorescence excitation photography of epidermal cellular proliferation.

BACKGROUND: Fluorescence excitation provides the ability to interrogate innate molecules whose radiation emission correlates with specific functional states of tissue. OBJECTIVES: The present study demonstrates the effectiveness of a novel ultraviolet (UV) fluorescence excitation photography system in its ability to image rapidly proliferating epidermal skin lesions by capturing endogenous fluorescence emissions attributed to tryptophan. METHODS: A clinical prototype UV fluorescence excitation photography system was used to acquire images of endogenous fluorescence ascribed to tryptophan. RESULTS: Twelve human subjects and 11 ex vivo samples with various skin lesions consistently exhibited increased endogenous fluorescence at 340-nm wavelength upon excitation at 295 nm in rapid epidermal proliferations, including psoriasis, actinic keratoses and basal cell carcinoma, compared with surrounding normal skin. In contrast, nonproliferating lesions showed decreased fluorescence. CONCLUSIONS: This simple but robust point-and-shoot imaging system may offer a clinically useful, noncontact, noninvasive device for the diagnosis and detection of skin disease. As opposed to structural imaging modalities, fluorescence excitation imaging at 295/340-nm wavelengths offers high-sensitivity, wide-field functional imaging of cellular proliferation without the need for externally applied dyes or lengthy image processing. Furthermore, the image is instantly available and does not require interpretation or reconstruction.

Evaluation of pharmacotherapy used on geriatric population in an institution of special regime with the screening tool of older persons' potentially inappropriate prescriptions (STOPP) criteria / Evaluación de la farmacoterapia en población geriátrica de una institución de régimen especial con los criterios the screening tool of older persons' potentially inappropriate prescriptions (STOPP)

Background: Geriatric patients represent a major challenge for appropriate prescription because they have significant changes in vital areas, multiple comorbidities among other things that encourage their fragility. In light of current evidence, the number of prescription errors increases with age and with the number of drugs USED, showing that people over 65 is at greater risk of medical error when more than 8 drugs are consumed. Objectives: To identify and describe the inappropriate medicines in elderly people in order to propose an institutional prescription guide based on the results of the application of the Screening Tool of Older Persons' Potentially Inappropriate Prescriptions (STOPP) assessment methodology. Methods: A cross-section observational study with a retrospective collection of information was carried out in order to identify the frequency of inappropriate prescriptions in 300 elderly patients that were over 65 years, with a consumption of more than 5 medications and applying the STOPP criteria. The study was made in a special regime medical institution, reviewing medical records and considering variables such as number of medications, indications, dosage, therapeutic duplication, interactions and contraindications, among others. Results: The principal diagnosis was hipertension (47%) followed by diabetes mellitus (10%) and other hypothyroidisms (4%).After applying the STOPP criteria to each of the medical records, it was found that 50.7% (152) of the studied population had at least one inappropriate prescription distributed as follows: 2 prescriptions had 4 STOPP criteria, 7 prescriptions had 3 STOPP criteria, 28 had 2 STOPP criteria and 115 had 1 STOPP criteria. Conclusions: It was found that half of the prescriptions have at least one inadequate prescribed criteria, being the most important the inappropriate use of not indicated drugs or without an indication. Finally, guidelines for the rational use of drugs in the elderly with every detail of this institution are proposed.

Antecedentes: Los pacientes geriátricos representan un reto importante para la prescripción apropiada porque tienen cambios significativos en sus funciones vitales y múltiples comorbilidades, entre otros, que los hacen frágiles. A la luz de la evidencia actual, el número de errores de prescripción aumenta con la edad y con el número de fármacos, demostrando que las personas mayores de 65 años tienen mayor riesgo de sufrir un error médico cuando se consumen más de 8 medicamentos. Objetivos: Identificar y describir los medicamentos inapropiados en adultos mayores con el fin de proponer una guía de prescripción institucional basada en los resultados de la aplicación de los criterios de evaluación de prescripción potencialmente inapropiados en adultos mayores (STOPP). Métodos: Se llevó a cabo un estudio observacional descriptivo de corte transversal, con recolección retrospectiva de información. Se cuantificó la frecuencia de prescripciones inadecuadas en 300 pacientes mayores de 65 años y con un consumo de más de 5 medicamentos. Posterior a esto se aplicaron los criterios STOPP por revisión de historias clínicas en una institución de régimen especial teniendo en cuenta variables como el número de medicamentos, indicación, posología, duplicidad terapéutica, interacciones, contraindicaciones, entre otros. Los criterios STOPP de prescripciones potencialmente inadecuadas contemplan el análisis por sistemas fisiológicos buscando posibles interacciones medicamentosas, contraindicaciones, duplicidad terapéutica y medicamentos que puedan representar un riesgo en adultos mayores por presentar cambios en su farmacocinética. Resultados: El diagnóstico principal es la presión arterial alta (47%), seguida de la diabetes mellitus (10%) y otros hipotiroidismos (4%). Después de aplicar los criterios STOPP para cada una de las historias clínicas, se encontró que el 50,7% (152) de la población del estudio tenía al menos una prescripción inadecuada distribuida de la siguiente manera: 2 recetas tenían 4 criterios STOPP, 7 recetas tenían 3 criterios STOPP, 28 tenían dos criterios STOPP y 115 tenían 1 criterios STOPP. Conclusiones: Se encontró que la mitad de las recetas tienen al menos un criterio de prescripción inadecuado, siendo el más importante el uso inadecuado de los medicamentos no indicados o sin indicación aparente. Por último, se proponen directrices para el uso racional de los medicamentos en los ancianos con todos los detalles de esta institución.

Nuestra experiencia en el manejo de los cavernomas de tronco, de tálamo y de ganglios basales / Our experience in the management of trunk, thalamus and basal ganglia cavernomas

OBJETIVO: Presentar nuestra experiencia en el manejo de los cavernomas de tronco cerebral, de tálamo y de ganglios basales. MATERIAL Y MÉTODO: Analizamos una serie de 16 pacientes asistidos en nuestra Institución, entre enero de 1990 y diciembre del año 2013. De ellos, 9 fueron varones y 7 mujeres. El rango de edad osciló entre 3 y 61 años. RESULTADOS: Siete debutaron con hemorragia cerebral, de ellos 4 se localizaban en protuberancia y 3 en el bulbo raquídeo. Siete pacientes tuvieron cavernomas múltiples, de ellos 3 tenían familiares con la misma enfermedad. El procedimiento diagnóstico de elección fue la resonancia nuclear magnética de cerebro en todos, y en los pacientes con cavernomas múltiples se completó el estudio con resonancia nuclear magnética de médula espinal. El tratamiento fue conservador en 9 enfermos, quirúrgico en 6 y radiocirugía estereotáctica en 1 enfermo; a éste paciente hubo necesidad de operarlo 6 meses después del tratamiento radiante por un resangrado voluminoso en la protuberancia. DISCUSIÓN: La cirugía es exitosa cuando el cavernoma se ubica a 2 mm de la piamadre, o del epéndimo. La radiocirugía puede ser causante de resangrado y de mayor volumen que las hemorragias previas. Por último, el tratamiento conservador sigue teniendo vigencia en los pacientes que se recuperaron neurológicamente y cuando se ubican en la profundidad del tronco cerebral, tálamo óptico o ganglios basales. CONCLUSIÓN: Cada paciente debe evaluarse individualmente para decidir el tipo de tratamiento, teniendo en cuenta la edad, la recuperación de los signos neurológicos, el volumen y la localización precisa del cavernoma

Objective: To present our experience in the management of brainstem, thalamus and basal ganglia cavernous malformations. Material and Method: We analyzed a series of 16 patients admitted to our Institution between January 1990 and December 2013. Nine of them were male and 7 female. Age ranged between 3 and 61. Results: Seven patients presented brainstem hemorrhage, 4 being pontine and the remaining 3 were medullary. Seven patients had multiple cavernomas, and 3 of them had a family background with the disease. The chosen diagnostic procedure was brain MRI in all patients; in patients with multiple cavernomas spine MRI was also requested. Nine patients received conservative treatment, 6 patients underwent surgery and one was treated with stereotactic radiosurgery but had to be operated on six months after radiation treatment due to voluminous re-bleeding at protuberance. Discussion: Surgery is successful when the cavernous malformation is placed 2 mm away from pia mater or ependyma. Radiosurgery can cause re-bleeding and of a greater volume than previous hemorrhages. Finally, conservative treatment is useful in patients who get neurologically recovered and when malformations are placed deep in brainstem, optic thalamus or basal ganglia. Conclusion: Each patient has to be individually assessed to individually assessed to make a decision regarding the type of treatment, taking into account age, recovery of neurological signs, volume, and precise location of cavernous malformation

Association of the PDE3A-SLCO1C1 locus with the response to anti-TNF agents in psoriasis.

Psoriasis is a prevalent autoimmune disease of the skin that causes significant psychological and physical disability. Tumor necrosis factor (TNF)-blocking agents have proven to be highly efficacious in the management of moderate-to-severe psoriasis. However, a significant percentage of patients do not respond to this treatment. Recently, variation at the PDE3A-SLCO1C1 (phosphodiesterase 3A-SoLute Carrier Organic anion transporter family member 1C1) locus has been robustly associated with anti-TNF response in rheumatoid arthritis. Using a cohort of 130 psoriasis patients treated with anti-TNF therapy, we sought to analyze the association of this locus with treatment response in psoriasis. We found a highly significant association between PDE3A-SLCO1C1 and the clinical response to TNF blockers (P=0.0031). Importantly, the allele that was previously associated with the lack of response to rheumatoid arthritis (G allele, single-nucleotide polymorphism rs3794271) was associated with a higher anti-TNF efficacy in psoriasis. The results of this study are an important step in the characterization of the pharmacogenetic profile associated with anti-TNF response in psoriasis.

Espondilodiscitis por Fusobacterium nucleatum: nueva forma de diagnóstico / Spondylodiscitis due to Fusobacterium nucleatum: New diagnostic method

Fusobacterium spp. son bacterias anaerobias Gram negativas. La osteomielitis vertebral por dichas bacterias es muy rara, de hecho, sólo podemos encontrar 11 casos en la literatura. Se presenta un caso de un varón de 46 años con dolor lumbar irradiado a la pierna derecha, de varias semanas de evolución y que no respondió al tratamiento con AINEs. Para el diagnóstico se utiliza la RMN, una biopsia con drenaje de la colección y una PCR universal seguida de secuenciación de ADNr 16S, con la que se obtuvo el diagnóstico microbiológico del paciente, identificando un Fusobacterium nucleatum como responsable. Posteriormente se pautó clindamicina como tratamiento final. En conclusión, la espondilodiscitis por Fusobacterium spp. es una entidad rara y su diagnóstico es a menudo difícil, tanto por las características clínicas como por la dificultad de obtener el diagnóstico microbiológico apropiado. La biopsia vertebral y las técnicas moleculares microbiológicas como la PCR ADNr Universal, son esenciales para la identificación del organismo y permiten la determinación de un diagnóstico y un tratamiento antibiótico apropiados.

Fusobacterium spp. are Gram negative anaerobe bacteria. Vertebral osteomyelitis caused by these bacteria is very unusual; in fact, we could only find 11 cases in the literature. We report the case of a male, 46 year-old patient who had had lumbar pain for several weeks that irradiated to the right leg, and did not respond to NSAID treatment. The work-up included MRI, biopsy with draining of the collection and a universal PCR followed by 16S rDNA sequencing. The latter was used to make the microbiologic diagnosis, which identified Fusobacterium nucleatum as the causative agent. Final treatment consisted of clindamycin. In conclusion, spondylodiscitis due to Fusobacterium spp. is a rare and difficult to diagnose entity, due both to its clinical characteristics and to the difficulty in making the right microbiologic diagnosis. Vertebral biopsy and molecular microbiologic techniques such as Universal PCR rDNa, are essential to identifying the organism, making the diagnosis and prescribing appropriate antibiotic therapy.

Extensive emphysematous pyelonephritis in a renal allograft: case report and review of literature.

Emphysematous pyelonephritis (EPN) is an acute, severe necrotizing infection of the renal parenchyma and perirenal tissue, which results in the presence of gas within the renal parenchyma, collecting system, or perinephric tissue. EPN of renal allograft is rare, with only 23 cases reported in Western literature. Here, we report a patient treated successfully with surgery. We also review the literature, focusing on old and new suggested classification systems for EPN.

Bone mass behavior after 1 year of different treatment strategies in prostate cancer patients subjected to androgen deprivation therapy.

The aim of this study was to evaluate bone mass changes after 1 year of four different types of pharmacological intervention. Ninety-seven prostate cancer patients treated with androgen deprivation therapy, and severe osteopenia or osteoporosis were retrospectively studied. Patients were divided in four groups. Group 1: 28 patients treated with denosumab, Group 2: 24 patients treated with alendronate, Group 3: 24 patients with no antiresorptive treatment and Group 4: 21 patients previously treated with alendronate and switched to denosumab. Dual X-ray absorptiometry was performed at baseline and after 1 year. Bone mass changes at the L2-L4 lumbar spine, femoral neck and total hip were evaluated. No differences were found at baseline. After 1 year, men receiving denosumab or alendronate (Group 1 and 2) showed a significant bone mass increase at the lumbar spine (+2.4 and +5.0 %, respectively), while no significant changes were observed in Group 3 and 4. At the femoral neck, Group 1 and 2 patients showed a significant bone mass increase (+3.7 and +3.6 %, respectively), while no significant changes were observed in Group 3 and 4. At the total hip, we observed a significant bone mass increase in Group 1 (+2.9 %) and a significant bone mass loss in Group 3 patients (-1.9 %). No significant changes were observed in Group 2 and 4. Denosumab increased significantly bone mass in all three dual X-ray absorptiometry standard sites, while alendronate did not at total hip. No benefit was observed in men previously treated with alendronate who switched to denosumab treatment.

[Spondylodiscitis due to Fusobacterium nucleatum: new diagnostic method]. / Espondilodiscitis por Fusobacterium nucleatum: nueva forma de diagnóstico.

Fusobacterium spp. are Gram negative anaerobe bacteria. Vertebral osteomyelitis caused by these bacteria is very unusual; in fact, we could only find 11 cases in the literature. We report the case of a male, 46 year-old patient who had had lumbar pain for several weeks that irradiated to the right leg, and did not respond to NSAID treatment. The work-up included MRI, biopsy with draining of the collection and a universal PCR followed by 16S rDNA sequencing. The latter was used to make the microbiologic diagnosis, which identified Fusobacterium nucleatum as the causative agent. Final treatment consisted of clindamycin. In conclusion, spondylodiscitis due to Fusobacterium spp. is a rare and difficult to diagnose entity, due both to its clinical characteristics and to the difficulty in making the right microbiologic diagnosis. Vertebral biopsy and molecular microbiologic techniques such as Universal PCR rDNa, are essential to identifying the organism, making the diagnosis and prescribing appropriate antibiotic therapy.
