The aim of this study is to raise up the effect of surgical thrombectomy among other alternative therapies. This retrospective study reports 6 patients (mean age 63 years) admitted with phlegmasia cerulea dolens. All patients underwent surgical venous thrombectomy associated with infracava filter insertion in 2 cases. One patient died in the early postoperative course. In all other cases we noticed good early and late outcome both on clinical examination and duplex scanning assessment. In conclusion, surgical venous thrombectomy can be considered as a good and efficient procedure in the presence of phlegmasia cerulea dolens in order to relieve ischemia and to prevent whenever possible severe chronic venous disorders. However, fibrinolytic therapy might achieve as good results as surgery. Thus, the latter is to be reserved to very severe veinous ischemia with limb loss threatening where fibrinolytic therapy fails or is contre-indicated. 相似文献

Sarcoidosis is a multisystem inflammatory disorder of unknown cause. It most commonly
affects the pulmonary system but can also affect the musculoskeletal system, albeit
less frequently. In patients with sarcoidosis, rheumatic involvement is polymorphic.
It can be the presenting symptom of the disease or can appear during its progression.
Articular involvement is dominated by nonspecific arthralgia, polyarthritis, and
Löfgren''s syndrome, which is defined as the presence of lung adenopathy, arthralgia
(or arthritis), and erythema nodosum. Skeletal manifestations, especially dactylitis,
appear mainly as complications of chronic, multiorgan sarcoidosis. Muscle involvement
in sarcoidosis is rare and usually asymptomatic. The diagnosis of rheumatic
sarcoidosis is based on X-ray findings and magnetic resonance imaging findings,
although the definitive diagnosis is made by anatomopathological study of biopsy
samples. Musculoskeletal involvement in sarcoidosis is generally relieved with
nonsteroidal anti-inflammatory drugs or corticosteroids. In corticosteroid-resistant
or -dependent forms of the disease, immunosuppressive therapy, such as treatment with
methotrexate or anti-TNF-α, is employed. The aim of this review was to present an
overview of the various types of osteoarticular and muscle involvement in
sarcoidosis, focusing on their diagnosis and management. 相似文献

Consanguinity is known to increase the burden of genetic disorders among offspring. However, the effect of consanguinity on a complex disorder like childhood asthma has not been studied previously. Therefore, we explored this relationship by studying the asthma prevalence in children between 6 and 14 years of age among the local Arab families of the United Arab Emirates (UAE) where consanguinity is known to be highly prevalent. A total of 1136 children from 295 families met our inclusion criteria. The prevalence of childhood asthma was higher among children in consanguineous families (43.3%) compared to non-consanguineous (22.6%, p < 0.001). There was a significant correlation between the degree of consanguinity and the number of asthmatic children per family (p = 0.0002). Girls from consanguineous families had proportionately more asthma (42.9%, p < 0.001) compared to boys (23.1%, p = 0.539).Paternal asthma in consanguineous families increased asthma risk for both boys and girls (p = 0.021 for boys, p < 0.001 for girls), while maternal asthma had no significant impact on asthma in offspring. Prevalence of childhood asthma was significantly higher in consanguineous families. The significant asthma predictors for girls from the consanguineous families were the degree of consanguinity and paternal asthma. The only predictor for boys was paternal asthma. These interesting observations merit further studies on both larger samples and in other consanguineous communities for confirmation. 相似文献

Agonistic monoclonal antibodies to CD40 (CD40 mAbs) have a puzzling dual therapeutic effect in experimental animal models. CD40 mAbs induce tumor regression by potentiating antitumoral T-cell responses, yet they also have immunosuppressive activity in chronic autoimmune inflammatory processes. CD40 mAbs are thought to act on antigen presentation by dendritic cells (DCs) to T cells. DCs can be distinguished as either immature or mature by their phenotype and their ability to generate an effective T-cell response. Here we found that, on human cells, although anti-CD40 led immature DCs to mature and became immunogenic, it also reduced the capacity of lipopolysaccharide (LPS) and tumor necrosis factor alpha (TNF-alpha)-matured DCs to generate a specific CD4 T-cell response. This inhibitory effect was related to rapid and selective apoptosis of mature DCs. Anti-CD40-mediated apoptosis was due to an indirect mechanism involving cooperation with the death domain-associated receptor Fas, leading to activation of Fas-associated death domain protein (FADD) and caspase-8. On human cells, CD40 activation by such agonists could, therefore, trigger immune responses to antigens presented by immature DCs, which are otherwise nonimmunogenic, by inducing maturation. On the other hand, anti-CD40 mAbs, by rapidly inducing apoptosis, may reduce the capacity of inflammatory signal-matured immunogenic DCs to generate an effective T-cell response. These results call for caution in CD40 mAb-based immunotherapy strategies. 相似文献

OBJECTIVE: To investigate the phenotypic features of infected lymphocytes in patients on prolonged and effective highly active antiretroviral therapy (HAART). DESIGN: We examined highly purified subsets of memory and naive CD4 T lymphocytes for the presence of replication-competent virus. METHODS: In 11 highly selected HAART-treated patients, we isolated highly purified CD45RO CD45RA CD4 T cells using a magnetic bead-based procedure. In some patients, a subsequent cell separation according to CD62L expression was performed. We quantified total viral DNA in freshly isolated T-cell subsets. To verify whether the virus was replication-competent, HIV RNA was measured in supernatants following cell activation. RESULTS: HIV DNA was detectable in the CD45RO and CD45RA CD4 T-cell subsets in 100% and 90% of the patients tested, respectively. In central memory CD45ROCD62L, effector memory CD45RO+CD62L-, truly naive CD45RACD62L, and CD45RA+CD62L- CD4 T cells, HIV DNA was found in 100%, 55%, 88%, and 50% of the patients tested respectively. HIV DNA was significantly higher in the CD45RO fraction than in the CD45RA subset and in the CD45ROCD62L fraction than in the three other CD45RA/ROCD62L+/- subsets. Detectable HIV RNA was found in the culture supernatants of CD45RO and CD45RA CD4 T-cell subsets in 80% and 66% of the patients tested respectively, and in CD45ROCD62L, CD45RO+CD62L-, CD45RACD62L, and CD45RA+CD62L- CD4 T cells in 100%, 100%, 100% and 50% of the patients tested respectively. CONCLUSIONS: In patients on prolonged and effective HAART, the pool of infected CD4 T lymphocytes consists predominantly of memory cells but also contains naive cells. 相似文献

Saffron (Crocus sativus L.) is a medicinal plant, originally cultivated in the East and Middle East, and later in some Mediterranean countries. Saffron is obtained from the stigmas of the plant. Currently, the use of saffron is undergoing a revival. The medicinal virtues of saffron, its culinary use and its high added value have led to the clarification of its phytochemical profile and its biological and therapeutic characteristics. Saffron is rich in carotenoids and terpenes. The major products of saffron are crocins and crocetin (carotenoids) deriving from zeaxanthin, pirocrocin and safranal, which give it its taste and aroma, respectively. Saffron and its major compounds have powerful antioxidant and anti-inflammatory properties in vitro and in vivo. Anti-tumor properties have also been described. The goal of this review is to present the beneficial effects of saffron and its main constituent molecules on neuropsychiatric diseases (depression, anxiety and schizophrenia) as well as on the most frequent age-related diseases (cardiovascular, ocular and neurodegenerative diseases, as well as sarcopenia). Overall, the phytochemical profile of saffron confers many beneficial virtues on human health and, in particular, on the prevention of age-related diseases, which is a major asset reinforcing the interest for this medicinal plant. 相似文献
