SummaryWe have shown previously that washed human platelets resuspended in Tyrode solution containing albumin and apyrase maintain their disc shape and their ability to aggregate upon the addition of low concentrations of ADP, providing fibrinogen is added to the suspending medium. We have now examined their responses to other aggregating and release-inducing agents. Collagen, arachidonate, thrombin, immune serum globulin, the ionophore A 23, 187 and phytohaemagglutinin from Phaseolus vulgaris caused aggregation and release of granule contents. The response to adrenaline was variable. Serotonin caused the platelets to change shape but no aggregation or release occurred. Addition of a small amount of plasma was necessary for ristocetin-induced aggregation. Polylysine caused immediate platelet-to-platelet adherence with little or no release of granule contents. Responses to collagen or thrombin were greater in a modified medium containing magnesium but no calcium; in this medium, aggregation caused by ADP or polylysine was followed by the release of granule contents whereas these agents caused aggregation without release in a medium with both calcium and magnesium. When protein was omitted from the suspending medium, platelet aggregation in response to ADP was variable. In this medium, collagen and thrombin caused more extensive release than in the albumin-containing medium. Aggregation by polylysine was accompanied by release and extensive lysis in the protein-free medium. Thus, the composition of the final resuspending medium has a major effect on the responses of washed human platelets to aggregating agents.

Цель исследования: изучение динамики показателей иммунитета и уровня кортизола у больных опийной наркоманией в процессе терапии синдрома отмены. Методика. В исследование включено 136 больных опийной наркоманией (инъекции экстракта опия) с сформировавшейся физической зависимостью. Пациенты получали в стационаре стандартную терапию с полной отменой наркотика. Исследование проводилось на следующих этапах: при поступлении в стационар (опийный абстинентный синдром - ОАС); на 5-7-е сут. терапии (переход в постабстинентное состояние - ПАС); на 25-28-е сут. лечения (становление терапевтической ремиссии - СТР). Лабораторные методы включали определение количества лимфоцитов с рецепторами CD3, CD4, CD8, СD16, с рецепторами к дофамину (D-RFC); содержание иммуноглобулинов М, G, А, уровня кортизола и циркулирующих иммунных комплексов (ЦИК) в сыворотке крови. Результаты. Основной иммуноэндокринный паттерн на всех этапах терапии синдрома отмены характеризуется дефицитом субпопуляций Т-лимфоцитов CD3, CD4, СD8; увеличением числа лимфоцитов с рецепторами к дофамину (D-RFC); активацией гуморальных факторов иммунитета (IgM, IgG, ЦИК); высокой концентрацией кортизола. На этапе ОАС и ПАС эти изменения были наиболее выражены; на 25-28-е сут. лечения отмечена позитивная динамика Т-лимфоцитов СD3 и цитотоксических Т-лимфоцитов (СD8); хелперы/индукторы CD4 оставались устойчиво сниженными; D-RFC лимфоциты, параметры гуморального иммунитета и концентрация кортизола - повышенными. Длительный срок наркотизации при употреблении высоких доз наркотика связан с большей выраженностью нарушений. Заключение. Установленная дизрегуляция параметров иммуноэндокринной системы у больных опийной наркоманией на всех этапах терапии синдрома отмены в наблюдаемые сроки (25-28 сут.) свидетельствует о неустойчивости достигнутой терапевтической ремиссии и необходимости проведения дальнейших реабилитационных мероприятий. The purpose: investigate changes in immunity parameters and cortisol level in subjects with opiate addiction during the treatment of opiate withdrawal syndrome. Methods. The study enrolled 136 subjects with opiate addiction with physical dependence receiving injections of opium extract. Patients received conventional therapy with complete opiate withdrawal. The study was performed at the following stages: at admission to the hospital (acute withdrawal syndrome (AWS); on days 5-7 of therapy (transition into post-withdrawal state - PWS); on days 25-28 of therapy (formation of therapeutic remission - FTR). Laboratory methods included determination count of lymphocytes with receptors CD3, CD4, CD8, СD16, with receptors to dopamine (D-RFC); the serum levels of IgМ, IgG, IgА, cortisol, circulating immune complexes (CIC). Results. The principal immunoendocrine pattern for all stages of withdrawal syndrome therapy is characterized in comparison to the reference normal values quantitative deficit of CD3, CD4, СD8 Т-lymphocyte subpopulations, increased count of lymphocytes with receptors to dopamine, activation of humoral immunity factors (IgM, IgG, CIC), high cortisol level. At AWS and PAS stages such changes are most pronounced; on days 25-28 of therapy positive changes in cytotoxic Т-lymphocytes (СD8) and Т-lymphocytes СD3 was revealed. CD4 count remained steadily reduced, count of lymphocytes with receptors to dopamine and cortisol level were elevated. Clinical and immunological analysis demonstrated that consumption of high opiate doses, long-term narcotization are associated with higher intensity of disorders detected. Conclusion. Dysregulation of immunoendocrine parameters was revealed in subjects with opiate addiction at all stages of withdrawal syndrome therapy within the term observed evidencing instability of therapeutic remission achieved and necessity in further rehabilitation events.

Introducción: El cáncer es una enfermedad de alta incidencia, con múltiples factores etiológicos y diferentes características evolutivas. Objetivo: Describir la supervivencia y la tendencia de las tasas de incidencia y mortalidad por cáncer de laringe y senos paranasales en Cali (Colombia) durante el periodo 1962 a 2015. Diseño: Estudio observacional descriptivo. Métodos: La información de incidencia, durante el periodo 1962 a 2012, se obtuvo en el RPCC y la mortalidad entre 1984-2015 de la SSPM. Elcomportamiento de la tendencia se evaluó con el porcentaje de cambio anual (APC) y la supervivencia relativa se estimó con el método de Ederer II. La estadificación se realizó con la AJCC. Resultados: Durante 1962 a 2012, se diagnosticaron 1623 casos nuevos de cáncer, 85.2% (1383 casos) fueron de laringe y 14.8% (240 casos) sinunasal 76% fueron hombres y el CCE fue el tipo histológico más frecuente 84.1% y 59.6% en laringe y sinunasal respectivamente. Se observó una disminución significativa del riesgo de cáncer de laringe en ambos sexos, siendo mayor la disminución en hombres (APC=-1,1*(ICD95%: -1,6; -0,7)). La disminución en la tasa de incidencia de cáncer de laringe CEC fue mayor en hombres (APC=-1,1*(ICD95%: -1,6; -0,6)) durante 1962-2012. Las tasas de mortalidad disminuyeron significativamente (APC=-2,5 (ICD95%:-3,6 -1,5)). La supervivencia relativa a 5 años durante el periodo 2008-2012, 43,5%; 93 pacientes se estadificaron con supervivencia: T3-T4 (41,5%) y T1-T2 (55,0%). Conclusiones: El riesgo del cáncer de laringe y sinunasal escamocelular asociado al tabaquismo disminuyó de manera significativa en hombres y mujeres de Cali durante los últimos 53 años.

Temporomandibular joint (TMJ) is commonly involved in various immune-mediated rheumatic disorders accounting for significant disability and impaired quality of life. The aim of our study was to assess inflammatory and immune parameters in patients with TMJ arthritis related to rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) and to identify potential relation with severity and dysfunction of TMJ pathology. We performed a cross-sectional study in a cohort of 433 consecutive RA, 32 JIA, 258 AS, and 103 PsA. Only patients presenting with clinically significant TMJ involvement (273) related to their rheumatic condition were included in the final analysis. TMJ involvement is traditionally described in chronic inflammatory rheumatic disorders, particularly in patients with higher levels of inflammation as detected in rheumatoid arthritis and psoriatic arthritis. Disease activity and severity, as well as biological and positive serological assessments (rheumatoid factor, anti-cyclic citrullinated peptide, IL-1) remain significant determinants of the severity of TMJ arthritis.
