Abstract
We report a severe case of kerion Celsi of the scalp in a previously healthy 13-year-old girl due to Trichophyton quinckeanum, an emerging dermatophyte species in Europe. The species was definitely identified by DNA sequencing and the patient was successfully treated by oral terbinafine for 6 weeks. Kerion Celsi is a severe inflammatory form of tinea capitis, which is characterised by a purulent discharge and alopecia [1]. It typically occurs in children infected with zoophilic dermatophytes, such as Trichophyton mentagrophytes, and an increasing number of cases caused by other Trichophyton species has recently been reported [2]. Herein we report a severe case of kerion Celsi of the scalp caused by the emerging species Trichophyton quinckeanum, which was successfully treated by oral antifungal.

Abstract
INTRODUCTION Fungal aspergillosis colonization and allergic bronchopulmonary aspergillosis (ABPA) can have a strong impact on the prognosis in cystic fibrosis (CF). We conducted round table discussions involving French experts from pediatric and adult centers caring for patients with CF, microbiologists, radiologists and pharmacists. The aim was to explore the current state of knowledge on: the pathophysiological mechanisms of Aspergillus and other micromycetes infections in CF (such as Scedosporium sp.), and on the clinico-biological diagnosis of ABPA. In perspective, the experts explored the role of imaging in the diagnosis of APBA, specifically CT and MRI; as well as the role of bronchoscopy in the management. We also reviewed the therapeutic management, including different corticosteroid regimens, antifungals and anti-IgE antibodies. CONCLUSION The diagnosis of ABPA in CF should be based on more standardized biological assays and imaging to optimize treatment and follow-up.

Abstract
The PCR-RLB (reverse line blot hybridisation) was applied as a molecular technique for the detection of members of Pseudallescheria and Scedosporium from sputum of patients with cystic fibrosis (CF). Fifty-nine sputum samples were collected from 52 CF patients, which were analysed by culture and PCR-RLB. Conventional and semi-selective culture yielded five positive samples, but the PCR-RLB hybridisation assay permitted the detection of members of Pseudallescheria/Scedosporium in 32 out of 52 patients (61.5%). In total, PCR-RLB yielded 47 positives. Pseudallescheria apiosperma was detected in 20 samples, while Pseudallescheria boydii and Pseudallescheria aurantiacum were detected in 17 and eight samples, respectively. Six samples gave a positive reaction with two distinct species-specific probes and one sample with three probes. In conclusion, the PCR-RLB assay described in this study allows the detection of Scedosporium spp. in CF sputum samples and the identification of Pseudallescheria apiosperma, P. boydii, S. aurantiacum, Scedosporium prolificans and Pseudallescheria minutispora.

Abstract
Identifying the role of fungi present in the domestic environment in the development of interstitial pneumonia can be a difficult clinical problem. We report a case of interstitial lung disease case occurring in a 53-year-old patient. He presented with profound hypoxemia (PaO(2) 54mmHg). Chest CT showed diffuse ground glass opacities. Initial blood tests for allergy and autoimmune disease were negative. Faced with a worsening of his clinical status after returning home he was hospitalized several times. At fibreoptic bronchoscopy, multiple white deposits were observed. Bronchoalveolar lavage with differential cell count was performed, revealing a 23% lymphocytosis. Serology for specific household molds showed moderate reaction to various molds found in homes, especially Stachybotrys chartarum. Pulmonary function tests revealed a moderate restrictive pattern with impaired diffusion of carbon monoxide and a bronchiolocentric interstitial pneumonia was found at lung biopsy. After a permanent move to a new residence, clinical parameters, radiological, biological and functional normalized. The final diagnosis was interstitial lung disease related to mycotoxins of S. Chartarum. The diagnosis of hypersensitivity pneumonitis to domestic mold or interstitial lung disease secondary to mycotoxins should be considered in patients presenting with interstitial pneumonia and requires specific investigations to ensure that an environmental cause with an allergic or toxic role is not missed.

Abstract
In addition to the serological systematic screening tests, kits to measure the avidity of toxoplasma IgG antibodies are currently available. Since high-avidity IgG toxoplasma antibodies have been shown to exclude recent infection, IgG avidity determination is especially useful in ruling out acute infection having occurred in the 3-4 prior months of pregnancy. We therefore compared the efficacy of two toxoplasma IgG avidity ELISA kits: SFRI (SFRI Laboratoire) and VIDAS Toxo-IgG avidity kit (bioMérieux). The agreement of the results from the 2 commercial assays were analysed using 55 serum samples, in terms of global mother-child Toxoplasma results and outcome, specially with light of the results of Toxoplasma antenatal, postnatal assays and of clinical follow up of children.

Abstract
Congenital toxoplasmosis results from foetus contamination by Toxoplasma gondii during pregnancy. It is a frequent and severe condition calling for close monitoring of mothers at risk. During the last decades, numerous advances have been made specially in the antenatal diagnosis. The congenital toxoplasmosis diagnosis relies currently on PCR test of amniotic fluid, with a sensitivity of 80%. More recently, real-time quantitative PCR has been developed to improve toxoplasmosis diagnosis. We therefore compared the diagnosis value of quantitative real-time PCR with our conventional PCR-hybridization for the diagnosis of congenital toxoplasmosis.

Abstract
Prophylaxis for short-term travel in malaria-endemic areas can be difficult for two reasons. The first is that currently available antimalarial drugs are becoming less effective because of the ability of the parasite to adapt to drug pressure. The second involves poor compliance with chemoprophylactic regimens due to the highly restrictive conditions of administration and adverse drug side-effects, especially in "healthy" subjects. The combination of atovaquone/proguanil (Malarone) could provide an answer to both these problems since it is not only effective on multiresistant strains of Plasmodium falciparum but also simplifies the conditions of administration and shows good tolerance in adults and children.

Abstract
Previous studies have shown that ferrochloroquine (FQ) exhibited an antimalarial activity against Plasmodium spp. The present work confirmed this activity, described the curative effect on P. vinckei and investigated the FQ toxicity in vitro and in vivo. The in vitro and in vivo growth inhibition of P. falciparum and P. berghei N, respectively, showed that FQ antimalarial activity was 1.5-10 times more potent than chloroquine. FQ completely inhibited the in vivo development of both chloroquine-susceptible and resistant P. vinckei strains and protected mice from lethal infection at a dose of 8.4 mg kg(-1) day(-1) given for 4 days subcutaneously or orally. This curative effect was 5-20 times more potent than chloroquine, according to the strains' resistance to chloroquine. At this curative dose, no clinical changes were observed in mice up to 14 days after the last administration. Nevertheless, the acute toxicity and lethality of ferrochloroquine seemed to be dependent on gastric surfeit. The FQ security index determined in vitro confirmed that it might be a promising compound.

Abstract
Human myiasis caused by Calliphora vicina is rare in Europe. Here we report a case of C. vicina infection occurring in the traumatic leg wound of a healthy 21-year-old man. Firstly, a progressive necrotizing infection developed in the wound despite administration of antibiotics. Aeromonas hydrophila was isolated from the wound samples. Secondly, during debridement, C. vicina first-instar larvae were isolated from the wound. To our knowledge, this is the first European case of C. vicina wound myiasis associated with severe A. hydrophila infection.

Abstract
Following our search for novel compounds with high antimalarial activity, a series of artemisinin (QHS) derivatives containing a ferrocenic nucleus was prepared and tested in vitro against Plasmodium falciparum strains. Two new metallocenic derivatives (1 and 3) were found as potent as QHS. All compounds showed a capacity to bind with ferroprotoporphyrin IX. A decrease in the Soret band absorbance of ferroprotoporphyrin IX, resulting from the addition of different drugs concentrations, was shown. The association stoichiometry of compounds to ferroprotoporphyrin IX appears to be 1:2 at equilibrium, with an intermediate 1:1 complexation. These results appear to strengthen the role of adducts between artemisinin derivatives and heme in generation of artemisinin radicals. Such interaction of artemisinin ferrocenyl derivatives with ferroprotoporphyrin IX and its biological significance could form a basis in future drug development.

Abstract
A few years ago we proposed a strategy for the synthesis of new ferrocene-chloroquine analogues replacing the carbon chain of chloroquine by hydrophobic ferrocenyl moieties. Now, this strategy has been applied to the antimalarial amino-alcohols class to afford new potentially active analogues of mefloquine and quinine bearing a substituted ferrocenic group. The pathway used for the synthesis of the mefloquine analogues includes the coupling of an aminomethyl substituted ferrocene carboxaldehyde with a lithio quinoline compound. On the other hand, the synthesis of quinine analogues was ensured by the 'inverse' reaction of a lithio aminomethyl ferrocene with a quinoline carboxaldehyde. The configurations of each diastereoisomer were unambiguously determined by spectroscopic data. The mechanistic interpretations were fully discussed. Ferrocenyl analogues of mefloquine and quinine exhibited a lower antimalarial activity than mefloquine and quinine themselves. Comparing optical isomers, those isomers dissimilar to ferrocenyl derivatives presented better antimalarial activities than those similar to ferrocenyl.

Abstract
In man, the two major metabolites of the antimalarial drug chloroquine (CQ) are monodesethylchloroquine (DECQ) and didesethylchloroquine (di-DECQ). By analogy with CQ, the synthesis and the in vitro tests of some amino derivatives of ferrochloroquine (FQ), a ferrocenic analogue of CQ which are presumed to be the oxidative metabolites of FQ, are reported. Desmethylferrochloroquine 1a and didesmethylferrochloroquine 2 would be more potent against schizontocides than CQ in vitro against two strains (HB3 and Dd2) of Plasmodium falciparum. Other secondary amino derivatives have been prepared and proved to be active as antimalarial agents in vitro, too.

Abstract
Malarial lactate dehydrogenase (LDH), which uses 3-acetyl pyridine adenine dinucleotide as coenzyme in a reaction leading to the formation of pyruvate from L-lactate, may be used to study the susceptibility of Plasmodium falciparum to a drug in vitro. Several methods to determine the activity of this enzyme are available. One, the colorimetric method of Makler and colleagues, was modified slightly, by using sodium-2,3-bis-[2-methoxy-4-nitro-5-sulphophenyl]-2H-tetrazolium-5 - carboxanilide (XTT) and following the reaction by measuring the optical density at 450 nm. Using two, culture-adapted strains of P. falciparum, this LDH assay was compared with the unmodified Makler's assay and with the isotopic microtest based on the incorporation of tritium-labelled hypoxanthine. Fresh, clinical P. falciparum isolates were also tested in the presence of several drugs, including chloroquine, mefloquine, quinine, halofantrine, atovaquone and qinghaosu derivatives. The results of the three assays were correlated for all the drugs tested except atovaquone. The two enzymatic assays are non-radioactive, rapid, reliable, inexpensive to perform and semi-automatic. However, they do require an initial parasitaemia of 2% with a haematocrit of 1.8%.
