ABSTRACT

In this paper, diagnostic tools are utilized to conduct a vulnerability analysis of monuments located in a coastal environment in accordance with a raft of standards drawn up by the International Organization for Standardization (ISO) 31000, in order to identify the main risks for Cultural Heritage in Havana (Cuba) and Cadiz (Spain). Vulnerability analysis is based on a Leopold matrix, which models the relationship between major hazards and pathologies in order to evaluate coastal influence and the risks for the conservation of cultural heritage. The quantitative matrix allows for a cause-effect analysis to be conducted for the main scenarios, related to the state of conservation. These relationships are a key step in risk assessment and treatment strategies. Major hazards have been identified by different public bodies and agencies to provide information about the probability and intensity of these variables in the vulnerability matrix. The combination of vulnerability index assessment, which depends on intrinsic variables and environmental scenarios, and knowledge of the main hazards in Havana and Cadiz, has provided useful tools to conduct risk assessments for cultural heritage conservation in coastal environments, where climate conditions, geomorphology and social issues are the main hazards, while vulnerability is associated with conservation plans. These tools provide information that will enable decision-makers in different coastal environments to prioritize strategies for cultural heritage preservation.

ABSTRACT

RESUMEN El término "LÁSER" es un acrónimo de "Light Amplification by the Stimulated Emission of Radiation" (en español "Amplificación de Luz por Emisión Estimulada de Radiación"). La utilización de la tecnología láser en Odontología ha tenido una constante evolución y desarrollo en los últimos 30 años. Se deben distinguir dos grandes grupos de láseres: De alta potencia o quirúrgicos y de baja potencia o terapéuticos. El más empleado en odontología pediátrica es el terapéutico o LLLT (o "blando"). El láser terapéutico está indicado para diversas anomalías tales como la hipersensibilidad, gingivitis, herpes, parestesias, neuralgias del trigémino, trismus, disfunción ATM, implantes, activación de químicos de blanqueamiento dental, entre otros. Este artículo pretende realizar una actualización de las aplicaciones del láser de baja potencia en el ámbito de la Odontología Pediátrica, así como la presentación de 4 casos clínicos representativos.


ABSTRACT The term "LASER" is an acronym for "Light Amplification by the Stimulated Emission of Radiation" (in Spanish "Amplificación de Luz por Emisión Estimulada de Radiación"). The use of laser technology in dentistry has had a constant evolution and development in the last 30 years. Two large groups of lasers should be distinguished: high-power or surgical and low-power or therapeutic. The most used in pediatric dentistry is the therapeutic or LLLT (or "soft"). The therapeutic laser is indicated for various anomalies such as hypersensitivity, gingivitis, herpes, paresthesias, trigeminal neuralgias, trismus, TMJ dysfunction, implants, activation of teeth whitening chemicals, among others. This article intends to perform an update of the applications of low power laser in the field of Pediatric Dentistry, as well as the presentation of 4 representative clinical cases.

ABSTRACT

BACKGROUND: Intravenous rituximab is a safe and effective option for the treatment of systemic non-Hodgkin B-cell lymphoma. The effectiveness of intralesional rituximab (ILR) in primary cutaneous B-cell lymphomas (PCBL) has been described in a small number of patients. OBJECTIVES: To evaluate the effectiveness, tolerance and adverse effects of ILR in patients with follicle centre (FCL) and marginal zone (MZL) PCBL. METHODS: This was an epidemiological observational multicentre study of patients with PCBL treated with ILR. RESULTS: Seventeen patients with MZL and 18 with FCL PCBL were included. The median number of lesions treated was two per patient. The treatment regimen used in 74% of the patients was a course of three injections in a single week at 1-month intervals. The dose per lesion and day of treatment was 10 mg in 71% of the patients. The median cumulative dose of rituximab per lesion was 60 mg (range 13-270) and per patient was 150 mg (range 20-360 mg). Complete response (CR) and partial response were achieved in 71% and 23% of patients, respectively. The median time to CR in patients who received 10 mg of ILR per lesion was 8 weeks. Similar response rates were observed in MZL and FCL. Median disease-free survival was 114·1 weeks. No parameters that significantly predicted CR were identified. Adverse reactions were recorded in 19 patients; the most frequent was localized pain at the injection site. Median follow-up was 21 months. CONCLUSIONS: Intralesional rituximab is a well-tolerated and effective treatment for FCL and MZL PCBL. It should be considered a useful alternative in patients with recurrent lesions and in which the sequelae of radiotherapy or surgery would be significant.

ABSTRACT

AIM: To analyze clinical manifestations, ictal, interictal and intraoperative EEG monitoring in patients with medical treatment refractory temporal epilepsy successfully controlled surgically. PATIENTS AND METHODS: Retrospective analysis, 33 patients. Mean age: 36 ± 11.40; number of monthly seizures: 9 ± 14.23; mean duration of disease: 22 years; number of anti-epileptic drugs: 3 ± 0.93; average monitoring duration on Intensive Video-EEG Monitoring Unit: 6.42 ± 3.61 days. Scalp EEG was recorded with surface electrodes placed according to the 10-20 international system. RESULTS: 158 seizures were recorded, most of them focal complex. 82% of patients presented aura. Disturbances of consciousness appeared in 94.3%, being more precocious than the automatisms in the majority of the sample. The most frequent and precocious automatisms were oromandibular. Intercritical: epileptiform activity was observed in 87.9% of cases; sharp waves in 93.1%, increasing with sleepiness in 97%. Polyspikes during REM sleep in 21.2%. Bilateral epileptiform activity in 21.1%. Ictal activity: changes on EEG activity was observed previous to clinical manifestation in more than 69%. Type of ictal onset: flattening (46%), rhythmic slow activity (41.7%). Ictal onset was focal in 48.9%. CONCLUSIONS: Detailed knowledge of clinical and electrical manifestations of temporal lobe epilepsies would allow a precocious diagnosis and a reduction of accessing time of these patients to surgical treatment in case of pharmaco-resistance.

ABSTRACT

Enteral nutrition (EN) is an effective method to meet the nutritional requirements in patients who have a deteriorated nutritional status. Objectives: To compare clinical and nutritional performance of two groups: Early Enteral Nutrition (EEN) versus Late Enteral Nutrition (LEN) of patients undergoing to total gastrectomy for gastric cancer. Material and Methods: 18 patients with resectable gastric cancer were studied with anthropometric, functional and biochemical parameters to assess nutritional status in the preoperative and postoperative period. They received a polimeric enteral formula (1 kcal/ml) in the postoperative period. They were randomly assigned to the type of nutrition (early or late). Results: The group with EEN had a significant improvement in the bicipital fold adequacy percentage and dynamometry. The LEN group had a significant decrease of albumin. The bloating was more frequent in the group with EEN. Conclusion: Early enteral nutrition is a safe nutritional support, effective and that brings nutritional benefits compared with late enteral nutrition in patients undergoing to total gastrectomy for gastric cancer.


La nutrición enteral (NE) es un método efectivo para cubrir los requerimientos nutricionales en pacientes que presentan un estado nutricional deteriorado. Objetivos: Comparar la Nutrición Enteral Precoz (NEP) versus Nutrición Enteral Tardía (NET) en la evolución clínica y nutricional de pacientes sometidos a gastrectomía total por Cáncer Gástrico. Material y Método: 18 pacientes con cáncer gástrico resecable, fueron estudiados con parámetros antropométricos, funcionales y bioquímicos que evalúan el estado nutricional, en el período preoperatorio y postoperatorio. Recibieron una fórmula enteral polimérica (1 kcal/ml) en el período postoperatorio. De manera aleatoria fueron asignados al tipo de nutrición (precoz o tardía). Resultados: El grupo con NEP presentó mejoría significativa del porcentaje de adecuación del pliegue bicipital y dinamometría. El grupo con NET presentó disminución significativa de la albuminemia. La distensión abdominal fue más frecuente en grupo con NEP. Conclusión: La Nutrición Enteral Precoz es un soporte nutricional seguro, eficaz y que trae consigo ventajas nutricionales en comparación con la Nutrición Enteral Tardía en el grupo de pacientes gastrectomizados totales por presentar cáncer gástrico.

ABSTRACT

OBJECTIVES: (1) To determine the feasibility of the use of a modified postural control test under altered sensory conditions in children over 8 years of age, and (2) to assess how deaf children use sensory information for postural control when they have normal or abnormal vestibular responses, and if hearing input from a unilateral cochlear implant, changes their postural behavior. PATIENTS: We selected 36 children, 8 to 11 years of age, with congenital or early-acquired profound sensorineural hearing loss, 13 of them with unilateral cochlear implantation and 22 normal-hearing children. METHODS: The Postural Control (PC) test consists of a force platform with 2 stimulation paradigm conditions: (1) standing on the platform with opened eyes; (2) standing on foam placed on the force platform with closed eyes. Implanted children were tested with the implant turn on and turn off in this condition, in order to evaluate eventual change in the postural control parameters when they have hearing habilitation. The body center of pressure distribution area (COP) and the body sway velocity (SV) were the parameter to evaluate the postural control. RESULTS: Deaf children were classified into two groups according with the vestibular responses: group A (n=28) Children with normal vestibular rotary responses; group B (n=8) children with hypoactive responses. Children in group A had diagnoses of syndromic and non-syndromic hereditary deafness, and children in group B had inner ear malformations, post-meningitis deafness, and one child had non-syndromic hereditary deafness with hypoactive vestibular response. In condition 1, when vestibular, somatosensory and visual information were enabled, the COP and SV values did not show any statistically significant differences between groups A, B and control. In condition 2, when visual information was removed and the somatosensory input strongly modified by standing on the foam, group B showed significant higher COP and SV values than groups A and control (p<0.05). In addition, the scalograms by wavelets of children in group B had higher amplitudes increasing the sway frequencies contents up to 3 Hz, not allowing them to maintain the up right stance in similar stimulation than in condition. Implanted children of the group A and B with the implant turn on, in the condition 2, did not show any significant difference in the SV, comparing when they had the implanted turn off. Group A p=0.395 and group B p=0.465 (Wilcoxon ranked test). CONCLUSION: These findings allow us to confirm that this postural test can be performed in children over 8 years old. Also our results suggest that deaf children with associated hypoactive vestibular responses included in our study, despite the etiology of the deafness, primarily use visual and somatosensory information to maintain their postural control. Hearing habilitation with a unilateral cochlear implant has no effect on the observed sensory organization strategy.

ABSTRACT

El Síndrome de Rasmussen es una enfermedad neurológica poco frecuente que inicia en la infancia pero puede progresar hasta la edad adulta. Se caracteriza por la presencia de epilepsia parcial continua y el desarrollo de epilepsia refractoria, datos relevantes en la explotación clínica, alteraciones en los estudios de neuroimágenes especialmente en la resonancia magnética y hallazgos histopatológicos característicos en la biopsia cerebral. Se ha relacionado esta entidad con un episodio previo de encefalitis que predispone a ua reacción inmunológica contra algunos componentes del encéfalo, lo cual lleva a un atrofia de un sólo hemisterio cerebral. Actualmente el tratamiento más efectivo en controlar las crisis convulsivas es la hemisferectomía, aunque algunos pacientes pueden tener mejoría transitoria con el uso de inmunoglobulina intravenosa .Se reporta el caso de una paciente quien reúne los criterios clínicos y radiológicos que hacen suponer sufre de esta enfermedad. Al momento de terminar de redactar este artículo está recibiendo dosis semanales de inmunoglobulina intravenosa para valorar respuesta clínica a la misma. Ante eventual falla terapéutica será sometida a una hemisferectomía de la cual una vez realizado el análisis histopatológico será reportado el caso. Palabras Claves : Síndrome de Rasmussen - Epilepsia Parcial Continua -Epilepsia Refractoria -Hemisferectomía-Inmunoglobulina intravenosa-Resonancia Magnética.

ABSTRACT

Serial Doppler sonographic impedance measurements represent the most common diagnostic method for noninvasive monitoring of kidney grafts. Severely elevated arterial impedance is almost always associated with graft dysfunction. However, we describe in the present work a renal transplant recipient with optimal graft function despite permanently elevated arterial impedance (pulsatility index (PI) ranging from 2.9-3.0, and resistive index (RI) = 1.0 as well as an abnormal venous flow pattern. In contrast, the contralateral graft from the same cadaver donors transplanted into a 17-year-old female patient displayed normal range PI and RI values in conjunction with a normal serum creatinine. Known causes of arterial impedance elevation such as rejection, cyclosporine, urinary obstruction, and external graft compression were excluded. Other extrarenal causes of high impedance, such as aortic insufficiency and reduced aortic compliance, were also excluded. No evidence of impaired venous outflow at the site of the anastomosis of the main renal vein to the iliac vein was found. Those findings support the view that impedance indexes are hemodynamic rather than functional parameters.

ABSTRACT

Cytomegalovirus (CMV) infections frequently develop in renal transplant patients. The transplanted kidney may be not only the source of infection but also the target for it. We report a case of primary CMV infection in a seronegative patient who received a graft from a seropositive cadaveric donor. The onset of CMV was clinically apparent on post-transplant day 22. Interestingly, soon after transplantation, the patient developed a long-lasting graft dysfunction episode for which diffuse endothelial-cell swelling was the most relevant finding at biopsy. On sonography, renal graft vascular impedance deteriorated and improved repeatedly during the follow-up period. We postulate that the patient had CMV-induced immunogenic-mediated endothelial-cell injury.

ABSTRACT

Amniocentesis performed after 24 weeks' gestation following ultrasonographic diagnosis of isolated unilateral hydronephrosis showed a de novo extra structurally abnormal chromosome in all cells examined. A combination of conventional and molecular cytogenetic techniques characterized the supernumerary marker as a dicentric and bisatellited marker derived from chromosome 22. At birth the infant presented hypoplasia of the right kidney, hearing loss on the left side and bilateral preauricular pits and skin tags. At three years, growth and neurological development were normal.

ABSTRACT

OBJECTIVE: To report a rare case of primary round cell liposarcoma of the urinary bladder. METHODS: A case of primary round cell liposarcoma of the urinary bladder in an 80-year-old female with hematuria is presented. The patient had a large, solid, non-circumscribed bladder tumor of 6.5 cms. The radiological, histological and immunohistochemical findings are discussed. RESULTS: The neoplasm was composed of isolated lipoblasts among numerous small round cells that were positive for S-100 and vimentin, and a high proliferation rate was demonstrated by Ki-67. The patient died 10 months after the histologic diagnosis. CONCLUSION: Primary liposarcoma of the urinary bladder is a very rare tumor with a poor prognosis that usually presents as a large tumor mass.

ABSTRACT

Disorders in vestibulo-ocular functions were studied in 4 patients with olivo-ponto-cerebellar atrophy (OPCA). The phenomenon of habituation, considered as a plastic property of the vestibulo-ocular reflex (VOR), was explored with a behavioural paradigm in these patients. When subjected to the habituation paradigm all patients presented a modified response opposite to that observed in normal subjects. The role played by the cerebellum in relation to VOR plasticity--well known in different experimental models--is analyzed. The hypothesis of a modification of the cerebellum's inhibitory action on vestibular nuclei neurons is put forward to explain the inversion of the VOR habituation phenomenon in these patients.

ABSTRACT

Trece enfermos, 5 hombres y 8 mujeres, fueron operados en la U.A.B.entre 1981 y 1983 por C.A.A. Nueve de estos enfermos tenían asociados factores predisponentes, 4 enfermos tenían síntomas muy sugerentes de padecer enfermedad biliar litiásica, pero no fue comprobada la litiasis en la operación. Se usaron los más variados test diagnósticos preoperatorios, siendo muy alta la incidencia de diagnósticos incorrectos. A todos los enfermos se les practicó colecistectomía con colangiografía intraoperatoria. Alta mortalidad se encontró en este cuadro, 15%. Se estudia la utilidad de los exámenes complementarios y de laboratorio en el diagnóstico preoperatorio. Se analiza toda la literatura, poniendo especial énfasis en algunos factores etiológicos. Se proponen medidas agresivas para el tratamiento de esta entidad
