阿尔及利亚中医药发展现状与分析

阿尔及利亚国民均可享受免费医疗制度,缺血性心脏病、脑卒中及AD等非传染性疾病发病率较高。针灸疗法已在阿尔及利亚获得民众认可,具有一定影响力。然而,受当地中医药人才培养不足、民众中医药知识匮乏、中医药尚未纳入医保等因素的限制,中医药在当地的临床应用和传播推广受到一定影响。建议从突破教育瓶颈、扩大人才队伍,开展针对性宣传、扩大中医药影响,推进中医药项目纳入医疗保险、促进政府立法保护等方面入手,提升扩大中医药传播力度和影响范围,推动中医药在阿尔及利亚的良性发展。     

The potential adverse effects of acrylamide on the oxidative stress response,fatty acids profile,and histopathological aspect of the Mediterranean Holothuria forskali respiratory tree

Acrylamide (ACR), organic compound, has been widely used owing to its broad spectrum of chemical and industrial applications. This study aims at evaluating the response of the antioxidant defense system, fatty acid composition and histopathological aspect in the respiratory trees of Holothuria forskali against ACR exposure under laboratory conditions. Holothuries were exposed to 5, 10, and 20 mg L⁻¹ ACR concentrations for 5 days. A significant increase in n-6 polyunsaturated fatty acids levels especially the arachidonic acid (ARA, C20:4n-6) and its precursor linoleic acid (LA, C18:2n-6) in ACR-treated organisms. Regarding the n-3 levels, eicosapentaenoic acid (EPA, C20:5n-3) levels were increased in treated groups despite an acute decrease in docosahexaenoic acid (DHA, C22:6n-3) levels was observed. Our results showed a significant increase in hydrogen peroxide, malondialdehyde, protein carbonyl, and metallothionein levels along with an alteration of the antioxidants status in all treated sea cucumbers. The exposure to ACR prompted the inhibition of Acetylcholinesterase activity in a concentration-dependent manner. The histopathological aspect was marked especially with the infiltration of coelomic cells which confirms our biochemical findings. Our study provided novel insights to create a link between redox status and fatty acid composition disruptions to better understand ACR-triggered toxicity.     

Hailey–Hailey Disease: An Update Review with a Focus on Treatment Data

Hailey–Hailey disease is a rare blistering dermatosis first described in 1939 by the brothers Howard and Hugh Hailey. Its incidence is estimated at 1/50,000. The inheritance is autosomal dominant with complete penetrance, but a variable expressivity in affected family members. Clinically, Hailey–Hailey disease presents between the third and fourth decade as flaccid vesicles and blisters on erythematous skin, giving rise to erosions, fissures, and vegetations. Maceration and superinfections are frequent. The lesions are typically distributed symmetrically within intertriginous regions such as the retroauricular folds, lateral aspects of the neck, axillae, umbilicus, inguinal, and perianal regions. The disease is characterized by a chronic relapsing course with spontaneous remissions and multiple recurrences. Severe disease can be very frustrating and have a major psychological and social impact. Given the dearth of evidence-based guidelines and large clinical trials, the assessment of the efficacy and safety of treatments is difficult. Treatments include topical and systemic agents, and procedural therapy such as lasers and surgery. This review provides a systematic search of the literature with a focus on classical and emerging treatment options for Hailey–Hailey disease.

     

Opsoclonus-myoclonus syndrome associated with Mycoplasma pneumoniae infection]

Mycoplasma pneumoniae infection is associated with various manifestations involving the central nervous system but it has never been reported as a potential aetiology of opsoclonus-myoclonus syndrome (OMS) in children. OBSERVATION: We report on a case in a 4-year-old girl who presented neurological manifestations compatible with an OMS, after a respiratory tract disease. Aetiological investigations revealed M. pneumoniae infection as specific IgM were present in the serum (Elisa). Evolution after corticosteroid, intravenous immunoglobulins and macrolide therapy was favourable as clinical symptoms disappeared. After a 12-month follow-up, the patient has no neurological sequela. CONCLUSION: M. pneumoniae infection should be added to the list of causes to be screened in OMS. Its pathophysiology remains unknown but may involve a dysimmune postinfectious mechanism.     

Endothelial nitric oxide synthase gene polymorphism is associated with Behçet's disease in Tunisian population

Nitric oxide (NO) is a molecule that plays a key role in many physiologic and pathologic processes. It is produced in vivo from the aminoacid l-arginine by a family of nitric oxide synthases (NOS). Endothelial NOS (eNOS) is a constitutively expressed isoform of NOS. The eNOS gene entails several polymorphisms, of which certain were investigated in Beh?et's disease (BD). We sought to establish the association of eNOS gene Glu298Asp polymorphism in exon 7 with susceptibility to BD. In this study, 135 Tunisian patients with BD and 157 healthy blood donor controls from the same geographic area were genotyped by polymerase chain reaction technique for eNOS polymorphism in exon 7. Our results showed that the distribution of the Glu298Asp genotype differed between BD patients and controls but did not reach statistical significance (p = 0.06). Allele Asp298 was significantly more frequent in healthy controls than in BD patients (p = 0.037, chi(2) = 4.33, OR = 1.01, 95% CI = 1.41-1.99). A significant difference was found (p = 0.004, OR = 1.26, 95% CI = 2.13-3.62) between BD patients with skin lesions and patients without this manifestation. Our findings suggest that Glu298Asp polymorphism of eNOS gene is associated with BD susceptibility as well as skin lesions.
