Status of the neuromyelitis optica spectrum disorder in Latin America.

Background: Neuromyelitis optica spectrum disorders (NMOSD) is an increasing diagnostic and therapeutic challenge in Latin America (LATAM). Despite the heterogeneity of this population, ethnic and socioeconomic commonalities exist, and epidemiologic studies from the region have had a limited geographic and population outreach. Identification of some aspects from the entire region are lacking.

Epidemiological findings of neuromyelitis optica spectrum disorders in a Venezuelan study.

Background: Neuromyelitis optica spectrum disorders (NMOSD), is a rare autoimmune inflammatory disease of the central nervous system. Since the countries of Latin America (LATAM) show contrast in geographic, social, environmental factors, and genetic heterogeneity, the information about NMOSD epidemiology in the region allows a better understanding of the disease and its clinical outcome.

Objectives: To determine the prevalence, relative frequency (RF), and clinical characteristics of NMOSD in a multiethnic Venezuelan cohort of patients with demyelinating disorders.

Short-segment transverse myelitis lesions in a cohort of Latin American patients with neuromyelitis optica spectrum disorders.

Study Design: Multicenter retrospective study.

Objectives: The aim was to determine the frequency and magnetic resonance imaging (MRI) features of short-segment transverse myelitis (STM) in patients with neuromyelitis optica spectrum disorders (NMOSD) during a myelitis attack.

Setting: Latin American diagnostic centres (Neuroimmunology Unit).

Frequency of brain MRI abnormalities in neuromyelitis optica spectrum disorder at presentation: A cohort of Latin American patients.

Background: Brain magnetic resonance imaging (BMRI) lesions were classically not reported in neuromyelitis optica (NMO). However, BMRI lesions are not uncommon in NMO spectrum disorder (NMOSD) patients.

Objective: To report BMRI characteristic abnormalities (location and configuration) in NMOSD patients at presentation.

Central Nervous System Idiopathic Inflammatory Demyelinating Disorders in South Americans: A Descriptive, Multicenter, Cross-Sectional Study.

The idiopathic inflammatory demyelinating disease (IIDD) spectrum has been investigated among different populations, and the results have indicated a low relative frequency of neuromyelitis optica (NMO) among multiple sclerosis (MS) cases in whites (1.2%-1.5%), increasing in Mestizos (8%) and Africans (15.

Management of relapsing-remitting multiple sclerosis in Latin America: practical recommendations for treatment optimization.

The Latin American MS Experts' Forum has developed practical recommendations on the initiation and optimization of disease-modifying therapies in patients with relapsing-remitting multiple sclerosis (RRMS). The recommendations reflect the unique epidemiology of MS and the clinical practice environment in Latin American countries. Treatment response may be evaluated according to changes in relapses; progression, as assessed by the Expanded Disability Status Scale and the Timed 25-foot Walk; and lesion number on magnetic resonance imaging.

COX-2 and sPLA2 inhibitory activity of aqueous extract and polyphenols of Rhizophora mangle (red mangrove).

The aqueous extract of Rhizophora mangle bark and its polyphenolic fractions showed remarkable in vitro antiinflammatory activity in a preliminary study. The low molecular weight fraction exhibited cyclooxygenase-2 inhibitory activity while the total aqueous extract and the low molecular weight fraction showed secretory phospholipase A(2) inhibitory activity.

Efficacy of Rhizophora mangle aqueous bark extract (RMABE) in the treatment of aphthous ulcers: a pilot study.

Objective: Rhizophora mangle aqueous bark extract (RMABE) (CIKRON-H), has been used as antiseptic and skin wound healing promoter. The present study was a randomised, single-blinded, placebo control trial conducted to asses the efficacy of RMABE in treating oral aphthous ulcers.

Research Design And Methods: Patients (n = 32) with aphthous ulcers were randomised to received placebo solution or RMABE topically, once a day, from Monday to Friday, until they healed.

Prevalence of Candida albicans and Trichomonas vaginalis in pregnant women in Havana City by an immunologic latex agglutination test.

We aimed to estimate the prevalence of Candida albicans and Trichomonas vaginalis in immunocompetent pregnant women living in Havana City, Cuba, with or without symptoms of vaginitis, using a sample of 640 women from 6 Gyneco-obstetrics hospitals, which represents 2.5% of total yearly pregnant women. Diagnosis was made using a new latex agglutination kit (Newvagin C-Kure, La Habana, Cuba).
