ABSTRACT

Peripheral giant cell granuloma (PGCG) is a benign reactive lesion of the oral cavity. Although PGCG is classified as a tumor-like lesion, it does not represent a true neoplasm, however it is often associated with a response of local irritation and trauma. Clinically, it appears as an exophytic growth with either sessile or pedunculated base, it can be located in gingiva or edentulous alveolar mucosa and usually does not exceed two cm in diameter. The following report describes the case of a 64-year-old female diagnosed with a PGCG of a particularly large size and rapidly evolving, located in the upper jaw area. The lesion was completely excised, and the diagnosis was confirmed by histopathology, there is no apparent recurrence in the area after 12 months of follow-up. A few cases of PGCG greater than 5 cm in diameter have been reported. Furthermore, exceptional cases might present an abnormal rapid growth as well. An opportune diagnosis based on clinical examination, radiographic and histopathological study are fundamental for a prompt and efficient treatment


El granuloma periférico de células gigantes (GPCG) es una lesión reactiva benigna de la cavidad oral en respuesta a una irritación local o a un traumatismo crónico. Si bien es una lesión de aspecto tumoral, no constituye una verdadera neoplasia. Se manifiesta como un crecimiento exofítico de base sésil o pediculada, localizado en encía o procesos alveolares edéntulos y no suele sobrepasar los 2 cm de diámetro. El presente reporte describe el caso de un GPCG de tamaño anormalmente grande y rápida evolución localizado en la zona del maxilar superior en un paciente femenino de 64 años. La biopsia escisional de la lesión confirmó el diagnóstico de GPCG y a 12 meses de seguimiento no se ha presentado recidiva. Se han reportado algunos casos de GPCG de más de 5 cm de diámetro. Además, casos excepcionales también pueden presentar un crecimiento rápido anormal. Un diagnóstico oportuno basado en el examen clínico, radiográfico e histopatológico es fundamental para un tratamiento rápido y eficaz

ABSTRACT

Objetivo: Conocer el perfil clínico, así como el significado pronóstico, de la presencia de niveles elevados de hormona paratiroidea (PTH) en pacientes ingresados por síndrome coronario agudo (SCA). Diseño y ámbito: Estudio observacional y prospectivo de pacientes ingresados por SCA en un único centro español durante un periodo de 6meses. Intervención y variables de interés: Se determinaron las concentraciones de PTH, calcidiol, calcitriol, NT-proBNP, proteína Creactiva, cistatinaC y fibrinógeno circulantes en las primeras 48h del ingreso y se realizaron modelos ajustados para predecir muerte o reingreso por SCA tras el alta. Resultados: Se reclutaron 161 pacientes (edad 67±14años; 75,2% varones) de los cuales 41 (25,5%) presentaron valores elevados de PTH. Se registraron 50 eventos adversos durante un seguimiento de 275 personas-año. Los pacientes con niveles elevados de PTH fueron en mayor proporción mujeres (21,2 vs. 39,0%) y de mayor edad (63,3 vs. 77,8años, ambos p<0,05). Asimismo, presentaron mayor riesgo cardiovascular y una peor evolución en el seguimiento (razón de tasas de incidencia: 2,64; IC 95%: 1,5-4,6). Sin embargo, en un modelo ajustado por la escala GRACE, los niveles de PTH no se mostraron como un factor de riesgo independiente (hazard ratio=1,1; IC 95%: 0,6-2,2); tampoco el resto de componentes del panel. Conclusiones: La proporción de pacientes con niveles elevados de PTH ingresados por SCA es elevada. Su presencia se asoció con un perfil clínico más adverso y peor evolución durante el seguimiento, aunque no resultó ser un predictor independiente de mal pronóstico (AU)


Objective: To know the clinical profile as well as the prognostic significance of elevated levels of parathyroid hormone (PTH) in patients admitted for acute coronary syndrome (ACS). Design and setting: Observational and prospective study of patients admitted for ACS in a single Spanish center during a period of six months. Intervention and variables of interest: The circulating concentrations of PTH, calcidiol, calcitriol, NT-proBNP, C-reactive protein, cystatinC and fibrinogen were determined within the first 48h at admission. We performed adjusted models to predict death or re-entry for ACS after hospital discharge. Results: A total of 161 patients were recruited (age 67±14 years, 75.2% were men). Forty-one (25.5%) patients had elevated PTH values. During follow-up for a period of 275 person-years, 50 adverse events were recorded. Patients with elevated PTH levels were proportionally more women (21.2 vs. 39.0%) and older (63.3 vs. 77.8 years, both P<.05). Likewise, they presented significantly more cardiovascular risk and a worse prognosis during follow-up (incidence rate ratio 2.64 CI 95%: 1.5-4.6). However, in an adjusted model by the GRACE score, PTH levels were not shown to be an independent risk factor (hazard ratio=1.1; 95% CI: 0.6-2.2), neither other components of the panel. Conclusions: The proportion of patients with elevated levels of PTH admitted for ACS was high. The presence of high PTH levels was associated with an unfavorable clinical profile and a worse outcome during the follow-up, although it was not an independent predictor of poor prognosis (AU)

ABSTRACT

Objetivo: Identificar el riesgo de complicaciones neurológicas de la anestesia espinal en los pacientes con un síndrome de Chiari tipo I preexistente y diferenciarlo del llamado “Chiari I adquirido” causado por un síndrome de hipotensión intracraneal, radiológicamente difícil de distinguir del anterior. Caso clínico: Mujer de 37 años, que tras recibir una punción dural durante la realización de una epidural analgésica para el parto, presentó cefalea pospunción dural (CPPD) recurrente. Se practicó resonancia magnética (RM) cerebral que puso de manifiesto malformación de Chiari tipo I (desplazamiento caudal de las amígdalas cerebelosas por el orificio magno) y engrosamiento difuso de las meninges. Aunque no lo había manifestado con anterioridad a la realización de la técnica epidural, la paciente presentaba cefaleas crónicas que se exacerbaban con las maniobras de Valsalva. La paciente fue tratada con analgésicos, cafeína y corticoides, y quedó asintomática. Tras 6 meses de seguimiento se realizó una nueva RM de control donde se observó la persistencia de los cambios anatómicos que definen el síndrome de Chiari tipo I, pero ausencia de las alteraciones meníngeas. Discusión: Tras una punción dural se puede producir el llamado “síndrome de hipotensiónin tracraneal”, motivado por la alteración del flujo y presiones del líquido cefalorraquídeo entre los compartimientos craneal y espinal. La pérdida continua de líquido cefalorraquídeo por el orificio de la punción originaría un gradiente de presión negativa que “empuja” las amígdalas cerebelosas hacia el orificio magno. ¿Es más acusado el cambio de presiones en aquellos pacientes con alteraciones previas, como el síndrome de Chiari? ¿Justifica la persistencia de una CPPD, a pesar del tratamiento? (...) (AU)


Objective: To identify the risk of neurological complications of spinal anesthesia inpatients with preexisting Chiari I malformation and to differentiate this entity from“ acquired Chiari I malformation”, caused by intracranial hypotension. These two entities can be difficult to distinguish radiologically. Case report: After undergoing dural puncture for epidural analgesia during delivery, a37-year-old woman developed recurrent postdural puncture headache (PDPH). Cerebral magnetic resonance imaging (MRI) revealed Chiari I malformation (displacement of the cerebellar tonsils into the foramen magnum) and diffuse dural gadolinium enhancement. The patient had experienced chronic headaches exacerbated by Valsalva’s maneuver before receiving epidural analgesia but had not reported these symptoms. She was treated with analgesics, caffeine and corticosteroids, which resolved the symptoms. After 6 months of follow-up, a second MRI scan revealed the persistence of the anatomical alterations characteristic of Chiari I malformation but without meningeal alterations. Discussion: After dural puncture, “intracranial hypotension syndrome” can occur, caused by alteration of cerebrospinal fluid (CSF) flow and pressure between the cranial and spinal compartments. Continuous CSF leak through the puncture site would cause a negative pressure gradient that would “push” the cerebellar tonsils toward the foramen magnum. Is the pressure change more marked in patients with prior alterations, such as Chiari malformation? Is the previous malformation the cause of the recurrent headache, despite treatment? Conclusion: Thorough clinical evaluation is required before spinal anesthesia is administered since severe neurological complications can occur in patients with undiagnosed Chiari malformations (AU)

ABSTRACT

OBJECTIVE: Rituximab is an anti-CD20 monoclonal antibody targeting B cells, which has been used with success in a wide variety of autoimmune diseases. The experience with this drug in patients with inflammatory myopathies (IM), nonetheless, is still limited. We review the literature and highlight several aspects in relation to therapy with rituximab in IM. METHODS: We performed a research in the MEDLINE DATABASE. All cases identified from the literature research and cases diagnosed in our Unit were included in the analysis. RESULTS: We identified 49 patients with IM treated with rituximab in the review of the literature carried out (31 female; 18 male), including our patients. Dermatomyositis (DM) was the most common disorder for which rituximab treatment was administered (69.4%). The other diseases treated included polymyositis (PM) 16.3%, antisynthetase syndrome (AS) 8.2%, one case with anti-SRP-syndrome and other with juvenile dermatomyositis. The median time to diagnosis was 48 (0.75-480) months. Sixty-five per cent (65.3%) of patients presented with skin manifestations, 89.8% with muscle weakness, 7.3% with arthritis, 16.3% with interstitial lung disease, and 7.3% with cardiomyopathy. Seventy-one (71.4%) of the patients received only one course of rituximab, 18.4% two courses, 4.1% three, 2% four and only 4.1% five. We have observed both among our patients and those reported in the literature a high rate of response to rituximab, 75% of our patients and 72.5% of those described in the literature showed a good response. The median time free of symptoms between two courses was 12 (6-19) months. Rituximab was generally well tolerated by all patients, with no serious adverse events. Most of the adverse events reported were mainly infections, particularly respiratory tract infections. CONCLUSIONS: It is our belief that rituximab may be an optimal therapeutic choice for inflammatory myopathies. Nevertheless, there is a need for additional studies in order to assess the optimal regimen of treatment in the different subsets, as well as the initial dose, combination of treatments and re-treatment schedule.

ABSTRACT

Gamma-hydroxybutyrate (GHB), a precursorto gamma aminobutyric acid (GABA), wasinitially employed as an anesthetic. As a relativelynovel drug, few people are aware of itsharmful effects and few studies have beenundertaken to investigate its long-term effectsor its action on developing tissues.We performed an experimental study onthe action of GHB on the developing eye, anorgan very closely related to the developmentof the CNS. Chick embryos were treated with20% or 30% dilutions of 100 ìl GHB at 7(30-31 HH) and 11 (37 HH) days of incubation(i.e., two doses per group), and the effectswere observed at 21 days of incubation (45HH). An ophthalmologic ultrasonographydevice (Hondex A/B SCAN IS-500) was usedto measure different eye parameters (cornealthickness; posterior surface of cornea – anteriorsurface of lens; anteroposterior diameter oflens; anteroposterior diameter of eye).We observed significant differencesbetween the treated and control groups asregards the thickness of the cornea and lens,and in the anteroposterior diameter of the eye.The present results demonstrate a possibleeffect of GHB on development (AU)

ABSTRACT

Gamma-hydroxybutyrate (GHB), a precursorto gamma aminobutyric acid (GABA), is currentlyone of the widest used drugs of abuse, with devastating effects. GHB produces a transient rise in the concentration of dopamine in the brain, inducing a stimulating effect. However, GHB can produce hallucinations, delirium, somnolence, hypotonia, confusion, and loss of balance. There may besubsequent progression to coma, with severerespiratory alterations due to CNS depression.The effects of GHB on humans are unpredictable,and its impact on the embryo and fetus is completely unknown. The purpose of our study was to contribute experimental data regarding the effects of GHB on development.Groups of chick embryos received 100 ìl ofGHB at dilutions of either 20% (GHB-A) or 30% (GHB-B) at 7 or 11 days of incubation,a further group serving as controls. After hatching, different cranial measurements were made using a Mitutoyo 500-331 series slidegauge in order to investigate possible effects ofthe drug on cranial development. At both doses studied, GHB significantly altered the transverse and vertical cranial measurements in comparison with vehicletreatedcontrols, suggesting a possible harmful effect on cranial development (AU)

ABSTRACT

Introducción: Realizamos un estudio experimental sobre los efectos que pueden provocar los CEM (campos electromagnéticos) en el desarrollo del globo ocular. Material y método: Montamos dos bobinas de Heltmholtz (generador CEM homogéneo) entre las cuales colocamos la incubadora (Masalles 65). El material biológico de estudio es el embrión de Gallus Domesticus, expuesto a los CEM, los 21 días de incubación. Hacemos tres experiencias con sus correspondientes grupos controles con 1 microtesla de intensidad y frecuencias de 30, 50 y 100 Hz, haciendo extracciones en los días 15 y 21 de incubación. Resultados: Los resultados significativos a los 15 días de incubación son: aumentos del grosor cornea en tratados con 30-50 Hz; distancia cara posterior cornea y cara anterior cristalino en tratados con 100 Hz; grosor cristalino en tratados con 50-100 Hz.E l eje antero posterior globo ocular se encuentra disminuido en tratados con 100 Hz. Los extraídos en día 21, disminuyen de manera significativa: grosor de cornea en tratados con 30 Hz; distancia cornea cristalino en tratados con 50 Hz; y grosor cristalino en tratados con 30 Hz. Mientras que el eje antero posterior globo ocular es significativamente mayor en tratados con 30 Hz(AU)

ABSTRACT

Introducción. Dentro de la sintomatología paraneoplásica de los cánceres se incluye la afectación neurológica a distintos niveles del sistema nervioso, tanto central como periférico, sin que esté bien definida su incidencia, variando la misma según el tipo de tumor. Caso clínico. Presentamos el caso de un varón de 73 años que ingresa por sospecha de polineuropatía de un mes de evolución. El diagnóstico se confirmó por electromiografía. Al efectuarse el estudio específico se encontró como única probable etiología un adenocarcinoma de próstata, con una amplia extensión en las cadenas ganglionares centrales y metástasis óseas, objetivadas por una tomografía computarizada abdominopélvica y gammagrafía ósea, no diagnosticado previamente. Conclusiones. Realizamos una revisión bibliográfica sobre la relación existente entre los síndromes paraneoplásicos neurológicos y las neoplasias de origen no pulmonar, en la que se ha encontrado una baja frecuencia de asociación entre ambos procesos, con escasas reseñas en la literatura sobre la asociación entre el adenocarcinoma de próstata y los procesos paraneoplásicos neurológicos. Existe una gran diversidad de expresión neurológica de estos síndromes, así como una asociación a distintos anticuerpos que podrían explicar un mecanismo etiopatogénico de carácter inmunitario. No existe un tratamiento efectivo a pesar de que éste suele ser agresivo y variado. El curso es con frecuencia rápidamente progresivo y conduce a la muerte en pocos meses (AU)


Introduction. Different neurological disorders affecting different levels of the nervous system, both central and peripheral, are included among the paraneoplastic symptomologies of cancers, although their incidence is not well defined and varies according to the type of tumour. Case report. We report the case of a 73-year-old male patient who was admitted with a suspected polyneuropathy that had been developing for one month. The diagnosis was confirmed by electromyography. The only probable aetiology found in the course of a specific exploration was an adenocarcinoma of the prostate, with a widespread distribution throughout the central ganglionic chains and bone metastases, which were observed by computerised tomography of the abdomino-pelvic region and bone gammography, and had not previously been diagnosed. Conclusions. We reviewed the literature on the relation between neurological paraneoplastic syndromes and neoplasias that are not of a pulmonary origin and we found a low rate of association between the two processes. The relation between adenocarcinoma of the prostate and neurological paraneoplastic processes receives very little attention. These syndromes vary greatly in their neurological expression, and there is a link with different antibodies that could explain an etiopathogenic mechanism of an immunitary nature. No effective treatment exists in spite of its usually being aggressive and varied. The disease often progresses quickly and leads to death after a few months (AU)

ABSTRACT

Ultrasonography was used to measure different ocular parameters in chick embryos exposed to low-frequency (50Hz) magnetic fields with flow intensities of 1 ?T, 0.1 mT, 0.5 mT, or 1 mT throughout their incubation. In comparison with unexposed control embryos, a significant reduction was observed in corneal thickness and in the anteroposterior diameter of the lens at 21 days of incubation (hatching) during exposure to the highest intensities (0.5 mT and 1 mT). By contrast, there was an increase in the anteroposterior diameter of the anterior eye chamber in embryos exposed to the lower magnetic field intensities (1 ?T and 0.1 mT). The anteroposterior diameter of the eye was smaller at 21 days of incubation in all the embryos exposed to magnetic fields as compared with the controls. The anteroposterior diameter of the lens was significantly smaller in embryos exposed to intensities of 0.5 mT and 1 mT in comparison with the controls (AU)


En nuestro estudio, se han usado medios ecográficos para medir diferentes parámetros oculares en embriones sometidos a campos magnéticos de baja frecuencia (50 Hz) con intensidades de 1mT, 0.1mT, 0.5mT, ó 1mT durante su incubación. Al comparar con embriones controles no expuestos se observó una reducción significativa en el grosor corneal y en el diámetro anteroposterior del cristalino en el día 21 de incubación en los embriones expuestos a las intensidades más altas (0.5mT y 1mT). Sin embargo, hubo un incremento en el diámetro anteroposterior de la cámara anterior del ojo en los embriones expuestos a las intensidades más bajas (1mT y 0.1mT). Observamos que el diámetro anteroposterior del ojo era menor a los 21 días de incubación en todos los embriones expuestos a campos magnéticos al compararlos con los controles. El diámetro anteroposterior del cristalino fue significativamente más pequeño en los embriones expuestos a intensidades de 0.5mT y 1mT con respecto a los controles (AU)

ABSTRACT

Objetivo. Utilidad de la anestesia locorregional y sedación en la dacriocistorrinostomía como alternativa a la anestesia general. Pacientes y método. Estudio sobre 20 enfermos intervenidos de dacriocistorrinostomía entre los meses de abril a octubre de 1999. Todos los procesos se llevaron a cabo por el mismo cirujano y bajo anestesia locorregional más sedación. Utilizamos crema EMLA® para la anestesia de la mucosa nasal y ropivacaína para las infiltraciones y bloqueo anestésico, así como midazolam y fentanilo en la sedación. Resultados. Objetivamos que en todos los casos la cirugía pudo realizarse bajo anestesia locorregional sin que existieran complicaciones destacables. La anestesia de la zona fue buena (evaluada mediante las variaciones hemodinámicas y el diálogo con el enfermo durante y después del proceso). El 70 por ciento de los pacientes refirieron la experiencia como buena y sólo un 5 por ciento como mala; el cirujano destacó un menor sangrado respecto al observado por él durante el proceso bajo anestesia general. A todos los enfermos se les dio el alta hospitalaria en las primeras 24 h. Conclusiones. El empleo de anestesia locorregional y sedación en la dacriocistorrinostomía constituye un método seguro y eficaz y es una alternativa válida a la anestesia general. Proponemos el uso de crema EMLA® en el taponamiento nasal y ropivacaína en las infiltraciones. El proceso es susceptible de realizarse como cirugía mayor ambulatoria (AU)
