ABSTRACT

RESUMEN Fundamento: El linfedema congénito primario es una condición rara con un componente genético importante que se caracteriza por edema crónico de la zona afectada. Objetivo: Presentar un linfedema congénito primario bilateral y discutir su origen. Presentación de caso: Se presentó un caso de linfedema congénito primario bilateral en un niño de 2 años de edad, sin antecedentes patológicos familiares de la enfermedad. Se discutieron sus posibles causas genéticas ya que existen varias mutaciones que explican su origen. Aunque no se pudieron realizar estudios genéticos para conocer la etiología exacta, existen evidencias clínicas de que no se trata de una enfermedad de Milroy, a menos que se presente como una mutación de novo. Se le realizó al paciente un seguimiento desde su diagnóstico hasta la actualidad. Conclusiones: Existen múltiples mutaciones genéticas que explican el origen de un linfedema congénito primario, por lo que no necesariamente debe tratarse de enfermedad de Milroy cuando este se presente. Se destacó como elemento importante que en este caso no se evidenciaron antecedentes familiares. Se empleó el tratamiento conservador como conducta fundamental a seguir, se evidenció en el paciente una notable mejoría clínica.


ABSTRACT Background: Primary congenital lymphedema is a rare condition with an important genetic component characterized by chronic edema of the affected area. Objective: To present a bilateral primary congenital lymphedema and discuss its origin. Case report: A case of bilateral primary congenital lymphedema was presented in a 2-year-old boy with no any family background of the disease. Its possible genetic causes were discussed since there are several mutations that explain its origin. Although genetic studies could not be performed to know the exact etiology, there is clinical evidence that it is not a Milroy's disease, unless it presents as a de novo mutation. The patient was followed up from diagnosis to the present. Conclusions: There are multiple genetic mutations that explain the origin of a primary congenital lymphedema, so it should not necessarily be Milroy's disease when present. A highlighted and important element was that in this case no any family background was evidenced. Conservative treatment was used as the essential conduct to follow up, a remarkable clinical progress was evidenced in the patient.

ABSTRACT

Acetylcholinesterase (AChE) is the key enzyme targeted in Alzheimer's disease (AD) therapy, nevertheless butyrylcholinesterase (BuChE) has been drawing attention due to its role in the disease progression. Thus, we aimed to synthesize novel cholinesterases inhibitors considering structural differences in their peripheral site, exploiting a moiety replacement approach based on the potent and selective hAChE drug donepezil. Hence, two small series of N-benzylpiperidine based compounds have successfully been synthesized as novel potent and selective hBuChE inhibitors. The most promising compounds (9 and 11) were not cytotoxic and their kinetic study accounted for dual binding site mode of interaction, which is in agreement with further docking and molecular dynamics studies. Therefore, this study demonstrates how our strategy enabled the discovery of novel promising and privileged structures. Remarkably, compound 11 proved to be one of the most potent (0.17 nM) and selective (>58,000-fold) hBuChE inhibitor ever reported.

ABSTRACT

PURPOSE: To monitor oncologists' perspective on cancer pain management. METHODS: An anonymized survey was conducted in two waves. First, over a convenience sample of oncologists known to be particularly concerned with the management of pain. Second, using a random sample of oncologists. RESULTS: In total, 73 and 82 oncologists participated in the first and second wave, respectively. Many oncologists reported to have good knowledge of analgesic drugs (95.9%), the mechanism of action of opioids (79.5%), and good skills to manage opioid-related bowel dysfunction (76.7%). Appropriate adjustment of background medication to manage breakthrough pain was reported by 95.5% of oncologists. Additionally, 87.7% (68.3% in the second wave, p = 0.035) of oncologists reported suitable opioid titration practices, and 90.4% reported to use co-adjuvant medications for neuropathic pain confidently. On the other hand, just 9.6% of oncologists participated in multidisciplinary pain management teams, and merely 30.3 and 27.1% reported to routinely collaborate with the Pain Clinics or involve other staff, respectively. Only 26.4% of the oncologists of the second wave gave priority to pain pathophysiology to decide therapies, and up to 75.6% reported difficulties in treating neuropathic pain. Significantly less oncologists of the second wave (82.9 vs. 94.5%, p = 0.001) used opioid rotation routinely. CONCLUSIONS: Unlike in previous surveys, medical oncologists reported in general good knowledge and few perceived limitations and barriers for pain management. However, multi-disciplinary management and collaboration with other specialists are still uncommon. Oncologists' commitment to optimize pain management seems important to improve and maintain good practices.

ABSTRACT

Alzheimer's disease (AD) is the most common form of dementia worldwide with an increasing prevalence for the next years. The multifactorial nature of AD precludes the design of new drugs directed to a single target being probably one of the reasons for recent failures. Therefore, dual binding site acetylcholinesterase (AChE) inhibitors have been revealed as cognitive enhancers and ß-amyloid modulators offering an alternative in AD therapy field. Based on the dual ligands NP61 and donepezil, the present study reports the synthesis of a series of indolylpiperidines hybrids to optimize the NP61 structure preserving the indole nucleus, but replacing the tacrine moiety of NP61 by benzyl piperidine core found in donepezil. Surprisingly, this new family of indolylpiperidines derivatives showed very potent and selective hBuChE inhibition. Further studies of NMR and molecular dynamics have showed the capacity of these hybrid molecules to change their bioactive conformation depending on the binding site, being capable to inhibit with different shapes BuChE and residually AChE.

ABSTRACT

The lack of an effective treatment for Alzheimer' disease (AD), an increasing prevalence and severe neurodegenerative pathology boost medicinal chemists to look for new drugs. Currently, only acethylcholinesterase (AChE) inhibitors and glutamate antagonist have been approved to the palliative treatment of AD. Although they have a short-term symptomatic benefits, their clinical use have revealed important non-cholinergic functions for AChE such its chaperone role in beta-amyloid toxicity. We propose here the design, synthesis and evaluation of non-toxic dual binding site AChEIs by hybridization of indanone and quinoline heterocyclic scaffolds. Unexpectely, we have found a potent allosteric modulator of AChE able to target cholinergic and non-cholinergic functions by fixing a specific AChE conformation, confirmed by STD-NMR and molecular modeling studies. Furthermore the promising biological data obtained on human neuroblastoma SH-SY5Y cell assays for the new allosteric hybrid 14, led us to propose it as a valuable pharmacological tool for the study of non-cholinergic functions of AChE, and as a new important lead for novel disease modifying agents against AD.

ABSTRACT

AIM: Noninvasive studies of the acetylcholinesterase (AChE) level in Alzheimer's disease (AD) patients can contribute to a better understanding of the disease and its therapeutic. We propose 3-(benzyloxy)-1-(5-[18F]fluoropentyl)-5-nitro-1H-indazole, [18F]-IND1, structurally related to the AChE-inhibitor CP126,998, as a new positron emission tomography-radiotracer. EXPERIMENTAL: Radiosynthesis, with 18F, stability, lipophilicity and protein binding of [18F]-IND1 were studied. In vivo behavior, in normal mice and on AD mice models, were also analyzed. RESULTS: [18F]-IND1 was obtained in good radiochemical yield, was stable for at least 2 h in different conditions, and had adequate lipophilicity for blood-brain barrier penetration. Biodistribution studies, in normal mice, showed that [18F]-IND1 was retained in the brain after 1 h. In vivo tacrine-blocking experiments indicated this uptake could be specifically due to AChE interaction. Studies in transgenic AD mice showed differential, compared with normal mice, binding in many brain regions. CONCLUSION: [18F]-IND1 can be used to detect AChE changes in AD patients.

ABSTRACT

Introducción: la limitación funcional y la discapacidad son las consecuencias fundamentales para los pacientes con espondilitis anquilopoyética, diversos factores han sido relacionados con la discapacidad y su repercusión en la calidad de vida de estos enfermos. Objetivo: evaluar la capacidad funcional y determinar factores asociados en los pacientes con espondilitis anquilopoyética. Métodos: se realizó un estudio transversal, descriptivo que incluyó 80 pacientes de la Consulta de Protocolo de Espondiloartropatías atendidos de junio de 2007 a julio de 2009. Se obtuvieron datos demográficos, clínicos, radiológicos y de laboratorio. Se evaluó la capacidad funcional aplicando el índice Bath Ankylosing Spondylitis Functional Index (BASFI) y se determinaron las asociaciones existentes. Resultados: predominó el sexo masculino (66,3 %). La edad media fue 40,1 años. La edad de inicio de la enfermedad, mayor de 20 años (73,8 %), presentó mayor BASFI (p=0,01), la ocupación laboral mostró diferencia significativa (56,14 %, p=0,04). El tiempo de demora del diagnóstico mayor de 10 años resultó significativo (p=0,03). El segmento cervical, la sacroilitis y el Bath Ankylosing Spondylitis Activity Index (BASDAI) reflejaron incremento del BASFI, significación estadística (p=0,01), no así, los reactantes de fase aguda y el HLA-B27. Conclusiones: la capacidad funcional se asocia de forma significativa con la edad de inicio de la enfermedad, el tiempo de demora del diagnóstico, la afectación del segmento cervical, la ocupación laboral, la sacroilitis y la actividad de la enfermedad.


Introducción: the functional limitation and the inability are the mayor consequences for patients presenting Ankylosing Spondylitis, Different factors have been related to inability and its repercussion in the quality of life of these patients. Objective: to assess the functional ability and to determine associated factors. Method: a cross-sectional and descriptive study was conducted including 80 patients from the Protocol Consultation of Spondylo-artropathies seen from June, 2007 to July, 2009. Demographic, clinical, radiological, and laboratory data were obtained. The functional ability was assessed applying BASFI rate (Bath Ankylosing Spondylitis Functional Index) and the existing associations were determined. Results: there was male sex predominance, (63.3 %). The mean age was 40,1 years. The disease onset period - older than 20 years old (73.8 %), had great BASFI (p=0 0.01); the occupation showed significant difference (56.14 %, p=0.04). The delay time from diagnosis, longer than 10 years, was significant (p=0.03). The cervical segment, sacroiliitis and BASDAI (Bath Ankylosing Spondylitis Activyt) showed a statistically significant BASFI increase (p=0.01), except the acute phase reactants and HLA-B27. Conclusions: the functional ability is significantly associated with the disease onset age, diagnosis delay time, involvement of cervical segment, occupation, sacroiliitis, and the disease activity.

ABSTRACT

Oxidative stress plays an important role in neuronal death in neurodegenerative disorders such as Parkinson's disease (PD). Hydroxyphenyl nitrones, derivatives of the nitrone spin trap alpha-phenyl-N-tert-butylnitrone (PBN), were synthesized and their antioxidant, anti-inflammatory and neuroprotective activity in neural cells evaluated. These hydroxyphenyl nitrones 5-7 were synthesized by reaction of the corresponding hydroxybenzaldehyde with N-tert-butyl hydroxylamine under microwave irradiation. They showed good peroxyl free radical scavenger capacities, analyzed by oxygen radical absorbance capacity (ORAC). Also inhibited peroxynitrite-mediated tyrosine nitration of alpha-synuclein in vitro and protected human neuroblastoma (SH-SY5Y) cells against SIN-1 and 6-OHDA toxicity when micromolar concentrations were used. Besides, the hydroxyphenyl nitrones evaluated showed anti-inflammatory activity modulating nitrite production in primary neural cell cultures of astrocytes and microglia treated with lipopolysaccharide (LPS), a potent inflammatory agent. These experimental data suggest a potential therapeutic use of these hydroxyphenyl nitrones against oxygen and nitrogen reactive species involved in neurodegenerative pathology.

ABSTRACT

BACKGROUND: it is known that vitamin D increases the population of superficial cells, so the objective of the present work was to evaluate the effect in Mexican postmenopausal women who were using or not oral calcitriol. METHODS: postmenopausal women with vaginal dryness that received at random: calcium 500 mg orally every 24 h or calcitriol 0.25 µg every 24 h during two months. At the beginning of treatment and at two months a vaginal Pap smear was performed. The maturation index was determined and the estrogenic value was calculated. Vaginal dryness was evaluated using an analog visual scales and vaginal by the moistening of a pH test strip. Student's t test was used for statistical analysis. RESULTS: 23 postmenopausal women were studied and divided as follows: group I (calcium) = 11 women and group II (calcitriol) = 12 women. In the analyzed parameters only the average of superficial cells was significantly greater at the end of treatment in the calcitriol group. CONCLUSION: calcitriol use increased the average of superficial cells in vaginal cytology, but didn't modify vaginal dryness.

ABSTRACT

La esperanza de vida en la artritis reumatoide (AR) es inferior a la de poblaciones control y existe estrecha relación con la comorbilidad. Identificar la frecuencia de la comorbilidad, mortalidad y variables relacionadas con su incremento. La muestra fue de 172 enfermos que cumplieron criterios del Colegio Americano de Reumatología, vistos en la Sección de Reumatología del Hospital Universitario Cmdte Manuel Fajardo en un período de 6 años. Se midieron 13 variables a 136 pacientes y se compararon con las de los fallecidos en dicho período, se realizaron medidas de tendencia central, dispersión, porcentajes, comorbilidad y relación con la mortalidad. El 65,1 por ciento de los casos tuvo comorbilidades (media de 1,58 por paciente), las más frecuentes fueron: hipertensión arterial (26,7 por ciento), diabetes mellitus (9,3 por ciento) y enfermedad tiroidea (8,7 por ciento). Hubo 9 fallecidos y una tasa de mortalidad de 5,2 por ciento; las causas de muerte mßs frecuentes fueron la enfermedad cardiovascular y el sangrado digestivo. En los fallecidos, las cifras más altas se hallaron en las variables: edad media (65,2 vs. 55,9), bajo nivel cultural (88,8 vs. 36,7 por ciento), velocidad de sedimentación globular (77 ± 29,9 vs. 49,8 ± 30,7) cuestionario autoaplicado para medir incapacidad (1,7 ± 0,74 vs. 0,9 ± 0,65) y comorbilidad (2,67 vs. 1,57). Más de la mitad de los pacientes tuvo comorbilidades, la mortalidad fue baja. El bajo nivel cultural, la velocidad de sedimentación globular, el cuestionario autoaplicado para medir incapacidad y el número de comorbilidades se relacionaron estrechamente con la mortalidad.


Life expectancy in rheumatoid arthritis (RA) is lower than that of control-populations, and there is a close relationship with morbidity. Objectives: to identify frequency of morbidity, mortality, and variables related to its increase. Sample included 172 sick persons fulfilled criteria of American College of Rheumatology, seen in Rheumatology Service of Comandante Manuel Fajardo University Hospital during 6 years. In 136 patients 13 variables were measured and were compared with that of deceased in such period and we applied measures of central trend, dispersion, percentages, morbidity, and relationship with mortality. The 65.1 percent of cases had morbidities (mean of 1.58 by patient), where the more frequent included: high blood pressure/26.7 percent, diabetes mellitus/9.3 percent, and thyroid disease/8.7 percent. There were 9 deceased and a mortality rate of 5.2 percent; the more frequent causes were: cardiovascular disease, and digestive bleeding. In deceased ones, higher figures were present in following variables: mean age (65.2 percent versus 55.9 percent), low cultural level (88.8 versus 36.7 percent), globular sedimentation speed (77 ± 29,9 versus 49.8 ± 40.7), self-applied questionnaire to measure inability, and the number or morbidities was closely related to mortality.

ABSTRACT

Introducción: El Lupus eritematoso sistémico (LES) es una enfermedad autoimmune con un riesgo elevado de desarrollar complicaciones. Objetivo: Conocer las tasas de supervivencia, factores pronósticos según características presentes al inicio de la enfermedad y causas de muerte de los pacientes con LES. Métodos: Se estudió una cohorte de 244 pacientes con diagnóstico de LES, atendidos en el Servicio de Reumatología del Hospital Hermanos Ameijeiras entre septiembre de 1991 y agosto del 2006. Se recogieron características sociodemográficas, clínicas, de laboratorio e histológicas presentes al inicio de la enfermedad. Se realizó un análisis estadístico para relacionarlas con la supervivencia. Se establecieron las causas de muerte, según los datos clínicos y al examen post morten, se estimó la supervivencia según el tiempo de diagnóstico y la fecha de última noticia, mediante el método de Kaplan - Meier. Resultados: Fallecieron 34 de los 244 pacientes, las causas más frecuentes de muerte fueron las infecciones, en el 32,3 por ciento de los casos .Las tasas de supervivencia a los 5, 10 y 15 años fueron de 93, 82,5 y 70 por ciento, respectivamente. Las variables asociadas a menor supervivencia fueron la trombocitopenia (p=0,005), antiDNA elevado (p=0,037), fracción C3 baja (p=0,000), fracción C4 baja (p=0,000), Addis de 2 h alterado (p=0,004), proteinuria de mas de 0,5 g (p=0,024), creatinina elevada (p=0,000) y filtrado glomerular disminuido (p=0,000). Fueron factores independientes asociados a baja supervivencia la trombocitopenia, la fracción C3 del complemento baja y creatinina sérica elevada. Conclusiones: La supervivencia de pacientes cubanos con LES es a los 5 años similar a la de varios estudios de países desarrollados, variables asociadas a baja supervivencia dependen de características propias de la enfermedad.


Introduction: The systemic erythematous lupus (SEL) is an autoimmune disase with an elevated risk for developing complications. Objective: To know the survival rates, prognostic factors according to the characteristics present at the onset of the disease and causes of death of the patients with SEL. Methods: A cohort of 244 patients with diagnosis of SEL that received attention at the Rheumatology Service of Hermanos Ameijeiras Hospital from September 1991 to August 2006 were studied. Sociodemographic, clinical, lab and histological characteristics observed at the onset of the disease were collected. A statistical analysis was made to relate them to survival. The causes of death according to clinical data and to the postmortem examination were determined, and survival was estimated in accordance with the diagnosis and the last notice date by Kaplan-Meier's method. Results: 34 of the 244 patients died. The most common cause of death was infection in 32.3 percent of the cases. The survival rates at 5, 10 and 15 years were 93, 82.5 and 70 percent, respectively. The variables associated with a lower survival were thrombocytopenia (p=0.005), elevated antiDNA (p=0.037), low C3 fraction (p=0.000), low C4 fraction (p=0.000), Addis at 2 h altered (p=0.004), proteinuria over 0.5 g (p=0.024), elevated creatinin (p=0.000) and reduced glomerular filtrate (p=0.000). The independent factors associated with low survival were thrombocytopenia, low complement C3 fraction and elevated serum creatinin. Conclusions: the survival of Cuban patients with SEL at 5 years is similar to the one reported by diverse studies conducted in developed countries. The variables associated with low survival depend on the own characteristics of the disease.

ABSTRACT

Se realizó un estudio descriptivo en los consultorios urbanos del policlínico área sur de Sancti Spíritus en el período comprendido de enero de 1997 a diciembre del 2000 con el objetivo de determinar el manejo de la enfermedad diarreica aguda en la atención primaria de salud. Se obtuvo como resultados que los medicamentos no se utilizan en el año 2000 en el 66,32% de los niños con diarreas. La terapia de rehidratación oral se utilizó en el 64,289% de los niños en el año 2000. Se arribó a las siguientes conclusiones que las sales de hidratación oral se utilizaron en todos los pacientes estudiados, los remedios caseros se fueron utilizando menos en el transcurso de los años y en el seguimiento y control de los mismos mejora considerablemente. No obstante se considera que se puede mejorar aún más en el manejo de está enfermedad.]AU[

ABSTRACT

Para evaluar la utilidad clínica de 2 métodos de pesquisaje de los anticuerpos antinucleares (AAN), se estudiaron 177 muestras de suero de pacientes con enfermedades autoinmunes reumáticas (EAR) y 131 con enfermedades autoinmunes no reumáticas. La sensibilidad de la inmunofluorescencia indirecta sobre cortes criopreservados de hígado de rata (IFI-HR) fue del 70,6 % para las EAR y de 92,9 % para el lupus eritematoso sistémico (LES), mientras que la sensibilidad de la aglutinación de partículas de látex recubiertas con antígenos nucleares (látex-LE) fue del 16,4 % para las EAR y del 34,3 % para el LES, títulos de AAN iguales o mayores de 1:640 fueron muy específicos de las EAR (97,0 %). características de la IFI-HR como la multiplicidad de patrones de fluorescencia (>3) y la presencia del patrón periférico, resultaron altamente específicos para el LES (97,2 y 93,5 %, respectivamente). La IFI-HR, al contrario del látex-LE, resultó un excelente método de pesquisaje de los anticuerpos antiácido desoxirribonucleico de doble cadena (ADNdc) (93,8 vs. 40,6 %), los cuales estuvieron asociados al patrón periférico de fluorescencia (p<0,0001), lo que permite recomendar la IFI-HR como método de elección para el pesquisaje de los AAN

ABSTRACT

Se estudiaron 514 muestras de suero de pacientes con enfermedades reumáticas examinadas simultáneamente por el método de radioinmunoanálisis (RIA) de fase líquida (Amersham, UK), con el objetivo de evaluar el valor diagnóstico del método de inmunofluorescencia indirecta sobre Crithidia luciliae(IFI-CI), fijada en láminas de producción nacional (Centro Nacional de Biopreparados, Cuba) para la detección de los anticuerpos anti-DNA de doble cadena (anti-DNAdc). Se encontró un coeficiente de concordancia Kappa de 0,658 p<0,0001 entre los resultados de ambos métodos y en base a la presencia o no de los anticuerpos anti-DNAdc. El coeficiente de correlación entre los resultados cuantitativos de los dos métodos fue de 0,78 p<0,01. La sensibilidad del método de IFI-CI para el diagnóstico del lupus eritematoso sistémico (LES), resulto ser similar al del RIA, pero este último alcanzó mayor especialidad diagnóstica para esta enfermedad. Estos resultados indican la utilidad del método de IFI-CI para la detección de los anticuerpos anti-DNAdc y de sus concentraciones séricas, y permiten clasificar a el RIA como el más específico para el diagnóstico del LES

ABSTRACT

Se obtuvo el extracto hístico, rico en antígenos nucleares, solubles a partir del polvo del timo de ternero. Se estudió la presencia de los anticuerpos anti-Sm y anti-RNP en 58 pacientes diagnosticados de lupus eritematoso sistémico (LES), y resultó ser el 26 y el 41 % respectivamente. Se confirmó el diagnóstico de la enfermedad mixta del tejido conectivo (EMTC) en seis pacientes, todos fueron positivos para los anticuerpos anti-RNP (100 %). Los niveles séricos de anticuerpos anti-DNA de doble cadena (dc) no guardaron preferencia por ninguno de los distintos pérfiles serológicos de anti-Sm y anti-RNP en el LES, aunque se observó un mayor número de pacientes con cifras de anti-DNAdc superiores a 100 */mL en los portadores de anti-Sm, anti-RNP o ambos anticuerpos (p < 0,05). La presencia de los anticuerpos anti-RNP en ausencia de los anti-Sm en los enfermos con conectivopatías, se asoció con una menor frecuencia de anticuerpos anti-DNAdc (p < 0,05)
