In the Horn of Africa, there is a high prevalence of tuberculosis that is reported to be partly driven by multidrug-resistant (MDR) Mycobacterium tuberculosis strictu sensu strains. We conducted a prospective study to investigate M. tuberculosis complex species causing tuberculosis in Djibouti, and their in vitro susceptibility to standard anti-tuberculous antibiotics in addition to clofazimine, minocycline, chloramphenicol and sulfadiazine. Among the 118 mycobacteria isolates from 118 successive patients with suspected pulmonary tuberculosis, 111 strains of M. tuberculosis, five Mycobacterium canettii, one ‘Mycobacterium simulans’ and one Mycobacterium kansasii were identified. Drug-susceptibility tests performed on the first 78 isolates yielded nine MDR M. tuberculosis isolates. All isolates were fully susceptible to clofazimine, minocycline and chloramphenicol, and 75 of 78 isolates were susceptible to sulfadiazine. In the Horn of Africa, patients with confirmed pulmonary tuberculosis caused by an in vitro susceptible strain may benefit from anti-leprosy drugs, sulfamides and phenicol antibiotics. 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

Background
The Integrated Management of Childhood Illness Strategy (IMCI) is effective in improving management of sick children, and thus child survival. It is currently recommended that in-service IMCI case management training (ICMT) occur over 11-days; that the participant: facilitator ratio should be ≤4:1 and that at least 30% of ICMT time be spent on clinical practice. In 2006–2007, approximately ten years after IMCI implementation, we conducted a multi-country exploratory questionnaire survey to document country experiences with ICMT, and to determine the acceptability of shortening duration of ICMT. 相似文献4.

As few data are available in the Pacific countries and territories of the Oceania region regarding nontuberculous mycobacteria, we retrospectively identified 87 such isolates from French Polynesia from 2008 to 2013 by hybridization using DNA-strip, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and partial rpoB gene sequencing. Partial rpoB gene sequencing classified 42/87 (48.3%) isolates in the Mycobacterium fortuitum complex, 28 (32.2%) in the Mycobacterium abscessus complex, 8 (9.2%) in the Mycobacterium mucogenicum complex, and 5 (5.7%) in the Mycobacterium avium complex. Two isolates were identified as Mycobacterium acapulcensis and Mycobacterium
cosmeticum by partial 16S rRNA gene sequencing. One isolate, unidentified by MALDI-TOF MS and yielding less than 92% and 96% sequence similarity with rpoB and hsp65 reference sequences, respectively, was regarded as a potentially new species. Samples from three patients exhibiting ≥2 Mycobacterium porcinum isolates and from one patient with emphysema and a lung abscess exhibiting 2 Mycobacterium senegalense isolates fulfilled the American Thoracic Society microbiological criteria for nontuberculous mycobacterial lung infection. Remote geographic areas, such as French Polynesia, are potential sources for the discovery of new mycobacterial species. 相似文献

During the last decade, growing efforts have focused on human papillomavirus (HPV) detection using liquid hybridization, conventional PCR, and real-time PCR-based methods to increase the overall proportion of patients participating in cervical cancer screening procedures. We proposed a new general HPV DNA real-time PCR on the Mx4000 (Stratagene) and LightCycler (Roche Diagnostics) systems usable for both cervical scrape specimens and urine samples. A linear range was obtained from 5 DNA copies to 8 log(10) DNA copies/ml, and intra- and interassay variations were between 1.8 and 4%. Cervical carcinoma and HPV DNA screening was performed in 333 individual women referred for gynecological examination at the university hospitals of Angers and Brest and enrolled in the PapU study. Among cervical specimens (n = 333), 45% were positive for HPV DNA, with a mean viral load at 5.00 log/ml (+/- 1.73). Among urine samples (n = 177), 37% were positive with a significant 50-fold-lower mean viral load (3.77 +/- 1.32 log/ml; P < 0.0001). Kappa agreement for HPV DNA between cervical and urine specimens was excellent (93%). Thus, we developed a highly sensitive and quantitative general HPV DNA real-time PCR method that allows mass screening of patients with HPV infection. The ongoing longitudinal and prospective multicenter PapU study should give us the opportunity to validate this method adapted to HPV DNA screening in urine samples in a larger population. 相似文献

Ethnopharmacological relevance
The article presents the local knowledge on medicinal plants and their relevance in managing health problems. Important ethnobotanical leads are given with priority species and disease categories, casting insight on future phytochemical and pharmacological studies.Aim of the study
The use of traditional medicinal plants has been an integral part of the traditional healthcare systems in Djibouti. However, scientific studies on the traditional herbal healing systems of the various cultural groups have never been undertaken. This study has, therefore, aimed at assessing plant-related ethnomedicinal knowledge of the people in Randa Region; prioritising the plants with respect to common disease categories and inferring about prospects of new pharmacological products.Materials and methods
Interview-based ethnobotanical field study was carried out to document the plant-based ethnomedicinal knowledge handed down to the present by the oral tradition of people living in 24 villages in Tadjourah District of Randa Region (north Djibouti). Informant Consensus Factors (ICF) and Fidelity Level (FL) values of the medicinal plants were calculated to check the level of informant agreement and the healing potentials of the species.Results
A total of 91 plant species that belong to 72 genera and 40 families were documented. Most of these species (92%) were collected from non-cultivated areas. Their local names and traditional uses in medicine were also studied. The plant family Fabaceae was represented by the highest number of taxa (17 species). Strong informant agreements hinted at good healing potentials of some species as shown by high values of consensus factors for eye diseases (0.98), mouth diseases (0.93), kidney problems (0.89) and microbial infections (0.84). Dodonea angustifolia, Solanum cordatum, Grewia erythraea, Acalypha indica, Acacia etbaica, Fagonia schweinfurthii, Solanum coagulans, Senna alexandrina and Grewia tembensis scored high FL values emerging as promising priority species for future pharmacological screening against microbial infections.Conclusion
The results of this study may inspire further ethnobotanical and ethnopharmacological research and investigations toward drug discovery in Djibouti and beyond. 相似文献9.

Methicillin-resistant Staphylococcus aureus (MRSA) infections were uncommon in children in Canada until the 1990s. Using a standardized case report form, treating physicians reported children hospitalized due to MRSA infections in Canadian hospitals through the Canadian Pediatric Surveillance Program in a 24-month period (2008 to 2010). Of 155 cases reported, 70% were ≤4 years of age and approximately one-third had an underlying medical condition. The most common clinical infections involved skin and soft tissue (69%), the lower respiratory tract (12%), and bone and joint (10%). Almost one-third had had contact with the health care environment in the previous year and 18% had a known household member with MRSA. Initial therapy with a beta-lactam alone occurred in 65%, while 22% included vancomycin. No child in this cohort died but 14% required admission to the intensive care unit. Of 143 reports of individual isolates, 93% were reported susceptible to trimethoprim-sulfamethoxazole, 63% to clindamycin and 50% to mupirocin.The present study involved only children hospitalized with MRSA infections. It may not be representative of the children treated as outpatients nor children in selected areas of Canada where MRSA infections may be more endemic. Further targeted surveillance to identify risks and treatment practices in these populations may be important. 相似文献

Human visceral leishmaniasis is endemic in the Mediterranean basin. Since most infections are sub-clinical or asymptomatic, host genetics can provide concrete evidence in determining disease outcome. SLC11A1/NRAMP1 is a candidate gene that may be related to host susceptibility versus resistance to intracellular pathogens. This study aimed to determine possible association of SLC11A1 polymorphisms with visceral leishmaniasis among Moroccan children. A total of 106 children who developed visceral leishmaniasis due to Leishmania infantum were enrolled in this study. The control group was composed of 137 unrelated children, 97 asymptomatic subjects (DTH+) and 42 healthy individuals (DTH) who had no evidence of present or past infection. Four polymorphisms were studied by PCR–RFLP and sequencing: (GT)n microsatellite in the 5′ exon 1; silent substitutions 469 + 14G/C in intron 4; amino acid substitution D543N in exon 15 and 823C/T polymorphism in exon 8. Thereafter, the frequencies of genotypes, alleles and haplotypes were estimated. Two polymorphisms were each significantly associated in the genotypes with visceral leishmaniasis: 823C/T in exon 8 and D543N in exon 15 when comparing visceral leishmaniasis and DTH+ groups. The results of haplotype frequencies suggested an evidence of association with resistance to visceral leishmaniasis for the “286GTG” and “288GCA” haplotypes, whereas, the “286GCG” haplotype appears to increase the risk to visceral leishmaniasis susceptibility.Our data provide insights into the possible role of SLC11A1 variation in visceral leishmaniasis susceptibility. These results must be regarded as preliminary but suggestive that further study with larger populations is worthwhile. 相似文献
