Abstract
A DNA microarray-based gene expression analysis study was performed with bovine spongiform encephalopathy (BSE) transgenic mice. Several genes were found to be overexpressed including the lysosomal enzyme cathepsin C, the chemokine CXCL13 and a number of genes related to cellular proliferation. The brains from terminal stage, BSE inoculated, 'bovinized', transgenic mice were subjected to immunohistochemistry with antibodies against these two proteins and Ki-67, a cell proliferation marker, to assess the biological relevance of the gene expression changes. Differential expression of cathepsin C and CXCL13 proteins and increased expression of Ki-67 was observed. These changes were localized to areas of deposition of PrP(res) and spongiform change and to areas showing an astroglial and microglial response. These findings suggest that these proteins are involved in the mechanisms leading to the establishment of transmissible spongiform encephalopathy.

Abstract
BACKGROUND Urinary tract infection (UTI) is the most common infection in renal transplant patients, but it is necessary to determine the risk factors for bacterial UTI in recipients of other solid organ transplants (SOTs), as well as changes in etiology, clinical presentation, and prognosis. METHODS In total, 4388 SOT recipients were monitored in 16 transplant centers belonging to the Spanish Network for Research on Infection in Transplantation (RESITRA). The frequency and characteristics of bacterial UTI in transplant patients were obtained prospectively from the cohort (September 2003 to February 2005). RESULTS A total of 192 patients (4.4%) presented 249 episodes of bacterial UTI (0.23 episodes per 1000 transplantation days); 156 patients were kidney or kidney-pancreas transplant recipients, and 36 patients were liver, heart, and lung transplant recipients. The highest frequency was observed in renal transplants (7.3%). High frequency of cystitis versus pyelonephritis without related mortality was observed in both groups. The most frequent etiology was Escherichia coli (57.8%), with 25.7% producing extended-spectrum β-lactamase (ESBL). In all transplants but renal, most cases occurred in the first month after transplantation. Cases were uniformly distributed during the first 6 months after transplantation in renal recipients. Age (odds ratio [OR] per decade 1.1, 95% confidence interval [CI] 1.02-1.17), female gender (OR 1.74, 95% CI 1.42-2.13), and the need for immediate post-transplant dialysis (OR 1.63, 95% CI 1.29-2.05) were independent variables associated with bacterial UTI in renal and kidney-pancreas recipients. The independent risk factors identified in non-renal transplants were age (OR per decade 1.79, 95% CI 1.09-3.48), female gender (OR 1.7, 95% CI 1.43-2.49), and diabetes (OR 1.02, 95% CI 1.001-1.040). CONCLUSIONS UTI was frequent in renal transplants, but also not unusual in non-renal transplants. Because E. coli continues to be the most frequent etiology, the emergence of ESBL-producing strains has been identified as a new problem. In both populations, most cases were cystitis without related mortality. Although the first month after transplantation was a risk period in all transplants, cases were uniformly distributed during the first 6 months in renal transplants. Age and female gender were identified as risk factors for UTI in both populations. Other particular risk factors were the need for immediate post-transplant dialysis in renal transplants and diabetes in non-renal transplants.

Abstract
Solid organ transplant recipients (SOTR) are at risk of serious influenza-related complications. The impact of respiratory co-infection in SOTR with 2009 pandemic influenza A(H1N1) is unknown. A multicentre prospective study of consecutive cases of pandemic influenza A(H1N1) in SOTR was carried out to assess the clinical characteristics and outcome and the risk factors for co-infection. Overall, 51 patients were included. Median time from transplant was 3.7 years, 5.9% of the cases occurred perioperatively and 7.8% were hospital-acquired. Pneumonia was diagnosed in 15 (29.4%) patients. Ten cases were severe (19.6%): 13.7% were admitted to intensive care units, 5.9% suffered septic shock, 5.9% developed acute graft rejection and 7.8% died. Co-infection was detected in 15 patients (29.4%): eight viral, six bacterial and one fungal. Viral co-infection did not affect the outcome. Patients with non-viral co-infection had a worse outcome: longer hospital stay (26.2 ± 20.7 vs. 5.5 ± 10.2) and higher rate of severe diseases (85.7% vs. 2.3%) and mortality (42.8% vs. 2.3%). Independent risk factors for non-viral co-infection were: diabetes mellitus and septic shock. Other factors associated with severe influenza were: delayed antiviral therapy, diabetes mellitus, time since transplantation <90 days and pneumonia. In conclusion, pandemic influenza A can cause significant direct and indirect effects in SOTR, especially in the early post-transplant period, and should be treated early. Clinicians should be aware of the possibility of non-viral co-infection, mainly in diabetic patients and severe cases. An effort should be made to prevent influenza with immunization of the patient and the environment.

Abstract
Citrus tristeza virus (CTV) is one of the most important virus diseases that affect citrus. Control of CTV is achieved by grafting selected virus-free citrus scions onto CTV-tolerant or -resistant rootstocks. Quarantine and certification programs are essential for avoiding the entry and propagation of severe strains of CTV. Citrus nurseries in Spain and central California (United States) maintain zero-tolerance policies for CTV that require sensitive, specific, and reliable pathogen-detection methods. Tissue-print (TP) real-time reverse-transcriptase polymerase chain reaction (RT-PCR) assay was compared with the validated TP enzyme-linked immunosorbent assay (ELISA), using the CTV-specific monoclonal antibodies 3DF1 and 3CA5, for CTV detection. In total, 1,395 samples from healthy and CTV-infected nursery and mature tree plants were analyzed with both methods. The total agreement between both detection methods was substantial (Cohen's kappa index of 0.77 ± 0.03). The diagnostic parameters of each technique (i.e., the sensitivity, specificity, and likelihood ratios) were evaluated in a second test involving 658 Citrus macrophylla nursery plants. Mexican lime indexing was used to evaluate samples with discrepant results in the analysis. For TP-ELISA, a sensitivity of 0.8015, a specificity of 0.9963, and a positive and negative likelihood ratio of 216.42 and 0.199, respectively, were estimated. For TP real-time RT-PCR, a sensitivity of 0.9820, a specificity of 0.8519, and a positive and negative likelihood ratio of 6.63 and 0.021, respectively, were estimated. These diagnostic parameters show that TP real-time RT-PCR was the most sensitive technique, whereas TP-ELISA showed the highest specificity, validating the use of the molecular technique for routine CTV-detection purposes. In addition, our results show that the combination of both techniques can accurately substitute for the conventional biological Mexican lime index for the detection of CTV. The calculation of diagnostic parameters is discussed, as a necessary tool, to validate detection or diagnostic methods in plant pathology. Furthermore, assessment of the post-test probability of disease after a diagnostic result and CTV prevalence allows selection of the best method for accurate and reliable diagnosis.

Abstract
BACKGROUND Monitoring assisted reproductive technology (ART) is essential to evaluate the performance of fertility treatment and its impact on birth rates. In Europe, there are two kinds of ART registers: voluntary and mandatory. The validity of register data is very important with respect to the quality of register-based observational studies. The aim of this paper is to determine the degree of agreement between voluntary and mandatory ART registers. METHODS The two sources for the data compared in this study (referring to 2005 and 2006) were FIVCAT.NET (an official compulsory Assisted Reproduction Registry within the Health Ministry of the Regional Government of Catalonia, to which all authorized clinics, both public and private, performing assisted reproduction in the region are obliged to report) and the register of the Spanish Fertility Society (SEF), to which data are provided on a voluntary basis. The SEF register data were divided into two groups: (i) data from clinics in Catalonia (SEF-CAT); (ii) data from the rest of Spain, excluding Catalonia (SEF-wCAT). The techniques compared were IVF cycle using patients' own eggs (IVF cycle) versus donor egg cycles. RESULTS For IVF cycles, the voluntary ART register reflected 77.2% of those on the official one, but the corresponding figure was only 34.4% with respect to donated eggs. The variables analysed in the IVF cycle (insemination technique used, patients' age, number of embryos transferred, pregnancy rates, multiple pregnancies and deliveries) were similar in the three groups studied. However, we observed significant differences in donor egg cycles with regard to the insemination technique used, pregnancy rates and multiple pregnancies between the voluntary and the official register. CONCLUSIONS Data from the voluntary ART register for IVF cycles are valid, but those for donor egg cycles are not. Further study is necessary to determine the reasons for this difference.

Abstract
PURPOSE About forty percent of the patients with primary Sjögren's syndrome (pSS) experience chronic neuropathic pain with normal electrodiagnostic studies. Two previous studies suggest that chronic neuropathic pain in pSS is due to small fiber neuropathy (SFN). Quantification of epidermal nerve fiber density after skin biopsy has been validated to diagnose small fiber neuropathy. METHODS Skin biopsy was performed in 14 consecutive pSS patients (satisfying the american-european classification criteria) with chronic neuropathic pain and normal electrodiagnostic studies suggesting SFN. RESULTS Fourteen female pSS patients exhibited chronic neuropathic pain [burning sensation (n=14), prickling (n=4), dysesthesia (n=8)] with paroxystic exacerbations (n=10) and allodynia (n=13), for a mean period of 18.4±12.4 months. Neuropathic pain involved mostly hands and feet (n=13), with a distal (n=9) and leg (n=4) predominant distribution. Neurological examination disclosed normal deep tendon responses and absence of motor weakness (n=14). Small fiber neuropathy was confirmed by skin biopsy in 13 cases. Epidermal nerve fiber density was decreased in distal [(n=12), mean 3.5±1.7 fibers/mm (N>6.9)] and proximal site of biopsy [(n=9), mean 7.04±2.63 fibers/mm (N>9.3)]. CONCLUSION Small fiber neuropathy is commonly responsible of chronic neuropathic pain in pSS. Prevalence, physiopathology and neurological evolution of such neuropathies still remain unknown.

Abstract
Rhizomelic chondrodysplasia punctata is a rare autosomal recessive disorder characterized by stippled epiphyses and rhizomelic shortening of the long bones. We report 3 subjects of rhizomelic chondrodysplasia punctata from India and the PEX7 mutations identified in them. The common PEX7-L292X allele, whose high frequency is due to a founder effect in the northern European Caucasian population, was not identified in these patients. Instead, 2 novel alleles are described, including 64_65delGC, which was present on a single PEX7 haplotype and could represent a common allele in the Indian population.

Abstract
[18F]fluorodeoxyglucose positron emission tomography (PET) is a noninvasive metabolic imaging modality that is well-suited to the assessment of activity and extent of large vessel vasculitis. PET imaging has demonstrated its usefulness in diagnosing giant cell arteritis (notably in its silent form), Takayasu's arteritis, and unclassified aortitis. PET imaging could be more effective than magnetic resonance imaging in detecting the earliest stages of vascular wall inflammation. The visual grading of vascular [18F]FDG uptake makes it possible to discriminate arteritis from active atherosclerosis, providing therefore high specificity. High sensitivity can also be achieved provided scanning is performed during active inflammatory phase, preferably before starting corticosteroid treatment. Prospective studies are needed to determine the exact value of PET imaging in assessing other vasculitis subsets, infectious aortitis, and large vessel vasculitis outcome and response to immunosuppressive treatment.

Abstract
We report two patients in whom angiosarcoma of the aorta (ASA) with distal emboli and skin metastases was initially clinically misdiagnosed as polyarteritis nodosa (PAN). Both presented with features highly suggestive of systemic necrotizing vasculitis, including constitutional symptoms, orchitis (in one), leg pain with sensory neuropathy, livedo, focal areas of skin necrosis, painful cutaneous nodules demonstrating vasculitis or inconspicuous changes on biopsy, raised acute phase reactants, and transient improvement with systemic corticosteroids. Repeated skin biopsies revealed an atypical endovascular cell proliferation with strong reactivity for factor VIII. Magnetic resonance angiography (MRA) demonstrated an intra-luminal aortic tumour at the infra-renal level. In retrospect, the (PAN)-like features appeared to involve exclusively the lower part of the body in these patients.

Abstract
Neuroinflammation elicited by PrP(res) (resistant prion protein [PrP]) deposits in the central nervous system (CNS) has been shown to involve cellular and oxidative stress responses in bovine spongiform encephalopathy (BSE) as well as in several murine models of transmissible spongiform encephalopathy (TSE). Additionally, deregulation of water homeostasis has been suggested to be a further component of the spongiform changes observed in TSEs. The aim of the present study was to characterize the pathogenic events occurring in the CNS of sheep with spontaneously arising classical scrapie. Brains from seven affected animals and two controls were subject to immunohistochemical and histochemical examinations. Semi-quantitative evaluation of PrP(res) deposits and spongiform changes throughout the encephalon confirmed that PrP(res) deposition elicits significant astroglial and microglial reactions, as evidenced by an increase in the number of glial cells and changes in glial cell morphology involving increased expression of vimentin. The altered expression of metallothionein and heat shock protein 25 (HSP25) suggested that this neuroinflammatory reaction entails cellular and oxidative stress responses. In contrast, there was no change in expression of the membrane-associated water channel aquaporin 1 when PrP(res) accumulated in the brain.

Abstract
OBJECTIVES Identification of factors associated with disease activity and B and T cell activation is a challenge in primary Sjogren's syndrome (pSS). Neurotrophins (NTs), recently reported as B cell antiapoptotic, and T-cell activation factors seem to be implicated in autoimmune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). METHODS Samples from 18 pSS patients and 12 control subjects were studied to determine serum levels of nerve-growth factor (NGF) and brain-derived neurotrophic factor (BDNF), and their relationships with T- and B-cell activation and disease activity. Peripheral blood mononuclear cells (PBMCs) from patients with pSS and controls were examined by flow cytometry for HLA-DR expression by activated T cells. B cell activation was evaluated by B cell activating factor (BAFF) serum levels measured by enzyme-linked immunosorbent assay (ELISA) and immunoglobulin (Ig) and free light chain (FLC) levels. RESULTS Mean serum levels of BDNF in pSS patients were significantly higher than in healthy controls and correlated directly with disease activity. NGF levels were associated with the subgroup of patients with hypergammaglobulinaemia. The pSS group was characterized by peripheral CD4+ and CD8+ T cell activation that correlated positively with BDNF and NGF levels, respectively. CONCLUSION NT levels are potential biomarkers for lymphocyte activation in pSS patients.

Abstract
OBJECTIVE To review personal and published observations of giant cell (temporal) arteritis (GCA) or polymyal-gia rheumatica (PMR) with familial or conjugal aggregation and emphasise on epidemiological, clinical and genetic features of such cases. METHODS We pooled data obtained from all cases of GCA or PMR with familial aggregation recruited in the department since 1976 and those from reports of familial or conjugal GCA or PMR published in the French-English literature since 1970. RESULTS During the study period, we diagnosed 460 patients (128 with isolated PMR, 227 with isolated GCA, 105 with PMR/CGA). No conjugal couples were observed in the whole series. No familial cases were identified among PMR patients, whereas the prevalence of familial GCA was 1 in 83 (1 in 250 to 500 expected by chance), as we identified 4 patients (brother-brother, sister with history of affected sister, and daughter with priory affected mother). An additional pair of sisters with TA, recruited several months after diagnosis, is also presented. Pooling data from 85 patients (74 with GCA) including our patients, representing 32 families and 8 conjugal pairs, enabled us to draw the following observations: 1) partial or full agreement in the clinical picture (GCA, PMR, or GCA/PMR) was observed in 96% of the siblings pairs, suggesting a common pathogenic mechanism; 2) five kindred were described in whom at least three members were affected; 3) the lag between manifested diseases in familial or conjugal pairs averaged 5.7 years, with synchronous or close disease occurrence in only 26% of the pairs; 4) 18 of 32 assessed patients (56%) carried the DR4 antigen. CONCLUSION Our survey on familial aggregation of GCA and PMR accumulated data pointing to a genetic predisposition. However, environmental contagious factors could have trigger synchronous disease onset in up to one-fourth of the cases.

Abstract
The Prionics-Check PrioSTRIP is a rapid chromatographic immunoassay for bovine spongiform encephalopathy (BSE) approved by the European Union in 2004. In this study, the PrioSTRIP was used to analyse PrP(BSE) in 16 different brain areas of nine confirmed BSE cases. The levels of PrP(BSE) in the different brain areas were plotted to give the brain PrP(BSE) distribution curve (BPDC) and compared with the BPDC obtained previously by Western blotting and enzyme-linked immunosorbent assay (ELISA) methods on the same samples. The distribution of PrP(BSE) in different areas of the brain was similar, irrespective of the test applied, indicating that each test could be used for the characterisation of BSE cases.

Abstract
The mechanisms by which introduced predators and long-lived seabirds interact and even coexist are still poorly known. Here, the interactions between the widely introduced black rat ( Rattus rattus (L., 1758)) and an endemic Mediterranean cavity-nesting seabird, the yelkouan shearwater ( Puffinus yelkouan (Acerbi, 1827)), were for the first time investigated for a set of 60 suitable breeding cavities throughout the entire breeding cycle of this seabird. Our results pointed out that rat visits to cavities were significantly higher when shearwaters had left the colony for their interbreeding exodus. Among the set of suitable breeding cavities, yelkouan shearwaters preferentially selected the deepest and the most winding cavities for breeding. Very few rat visits were recorded at the shearwater-occupied cavities and no predation event was recorded. These intriguing results reveal a low level of interaction between introduced black rats and yelkouan shearwaters, which may have facilitated their long-term coexistence for thousands of years on some Mediterranean islands.

Abstract
OBJECTIVE This study aimed to evaluate at-home phlebotomy and the satisfaction of iron-overload patients and healthcare workers with the procedure. METHODS Forty-two patients underwent at-home phlebotomy between 2003 and 2006. The phlebotomy was performed by the patient's nurse, who was trained by the private healthcare firm that also took charge of the disposal of the blood products. Data concerning these phlebotomies were collected via telephone interviews with all 42 patients, as well as 35 nurses and 40 primary-care physicians. The Limousin Regional Health Observatory processed the data collection. RESULTS Ninety percent (38/42) of the patients, 80% (28/35) of the nurses and 67% (27/40) of the primary-care physicians responded. For 80% of the patients, phlebotomy volume and frequency were as prescribed. Patients chose home phlebotomy for personal reasons, or because of the limited availability of French Blood Establishment facilities (68%), or in response to being offered it by their hospital physician (32%). For 81.6% of the patients, at-home phlebotomy was more satisfactory than phlebotomy in hospital or at the French Blood Establishment and, for 84%, the constraints required were fully acceptable. The nurses considered that these homecare procedures were within their area of responsibility (100%), but felt that the remuneration was insufficient (65%). Ninety-six percent of the primary-care physicians said they were correctly informed, but only 40% felt that they were truly committed to the procedure. CONCLUSION At-home phlebotomy is feasible, less costly than institutional phlebotomy and improves patient comfort.

Abstract
Millions of hectares of future timber concessions are slated to be implemented within large public forests under the forest law passed in 2006 by the Brazilian Congress. Additional millions of hectares of large, privately owned forests and smaller areas of community forests are certified as well managed by the Forest Stewardship Council, based on certification standards that will be reviewed in 2007. Forest size and ownership are two key factors that influence management objectives and the capacity of forest managers to achieve them. Current best ecological practices for timber production from Brazil's native Amazon forests are limited to reduced-impact logging (RIL) systems that minimize the environmental impacts of harvest operations and that obey legal restrictions regarding minimum diameters, rare species, retention of seed trees, maximum logging intensity, preservation of riparian buffers, fire protection, and wildlife conservation. Compared with conventional, predatory harvesting that constitutes >90% of the region's timber production, RIL dramatically reduces logging damage and helps maintain forest cover and the presence of rare tree species, but current RIL guidelines do not assure that the volume of timber removed can be sustained in future harvests. We believe it is counterproductive to expect smallholders to subscribe to additional harvest limitations beyond RIL, that larger private forested landholdings managed for timber production should be sustainable with respect to the total volume of timber harvested per unit area per cutting cycle, and that large public forests should sustain volume production of individual harvested species. These additional requirements would improve the ecological sustainability of forest management and help create a stable forest-based sector of the region's economy, but would involve costs associated with lengthened cutting cycles, reduced harvest intensities, and/or postharvest silviculture to promote adequate growth and regeneration.

Abstract
We describe a 62-year-old woman with slowly growing usual nodular goitre in whom diffuse giant cell arteritis (GCA) of the thyroid arteries was found upon thyroidectomy, revealing otherwise unsuspected biopsy-proven temporal arteritis. To our knowledge, this association had been previously reported in only three instances. In each case, GCA of the thyroid arteries appeared clinically silent, did not produce significant glandular dysfunction, and was uncovered thanks to a planned thyroidectomy for nodular goitre. These observations highlight that thyroid artery involvement by GCA, even widespread, as in our patient, may be overlooked clinically and may produce little or no thyroid dysfunction.

Abstract
Molecular profiling of the proteinase K resistant prion protein (PrP(res)) is a technique that has been applied to the characterisation of transmissible spongiform encephalopathy (TSE) strains. An interesting example of the application of this technique is the ability to differentiate, at the experimental level, between bovine spongiform encephalopathy (BSE) and scrapie infection in sheep, and to distinguish between classical and atypical BSE and scrapie cases. Twenty-six BSE cases and two scrapie cases from an active TSE surveillance program and diagnosed at the PRIOCAT, TSE Reference Laboratory (Centre de Recerca en Sanitat Animal, Universitat Autònoma de Barcelona, Catalunya, Spain) were examined by Western blotting. Molecular profiling was achieved by comparing the glycosylation profile, deglycosylated PrP molecular weight and 6H4/P4 monoclonal antibody binding ratio. The results obtained during the characterisation of these field cases indicated an absence of atypical BSE cases in Catalunya.

Abstract
During active surveillance for transmissible spongiform encephalopathies (TSEs) in sheep, an initial reactor was detected using a rapid test on a brain sample. Immunohistochemistry confirmed an atypical TSE presentation that closely resembled the previously described Nor98 cases. Sequencing of the prnp gene confirmed the ARQ/AHQ genotype with the L141F mutation at codon 141 associated with this phenotype. The head, including the brain and cranial lymphoid tissues, was sampled and examined thoroughly. Non-purulent encephalitis, with ectopic lymphoid follicle formation within the brain, was diagnosed concomitant to the TSE. When scrapie-associated prion protein (PrP(sc)) deposition was studied by immunohistochemistry there was a noticeable lack of lymphotropism. The distribution of PrP(sc) in the brain differed considerably from that of classical scrapie cases. Astrogliosis and microgliosis were demonstrated by histochemical procedures.

Abstract
The distribution of interstitial cells of Cajal (ICC) and neurotransmission were investigated in lower oesophageal sphincter (LES) circular muscle strips from Sprague-Dawley (SD) rats, Ws/Ws mutant rats and their wild-type (+/+) siblings. Intramuscular c-Kit-positive cells, confirmed to be ICC-IM by electron microscopy, were observed throughout both muscle layers from SD and +/+ rats. In contrast, c-Kit-positive, ultrastructurally typical ICC-IM were absent in Ws/Ws. LES strips from Ws/Ws rats showed increased spontaneous contractile activity. Strips from SD and +/+ rats, responded to electrical neuronal stimulation with a relaxation that was in part L-NNA and in part apamin sensitive, followed by a contraction which was decreased by atropine. In Ws/Ws rats, similar to +/+ rats, neurally mediated relaxation was L-NNA and apamin sensitive and the contraction was decreased by atropine. We conclude that in the rat LES, relaxation is mediated by NO and an apamin-sensitive mediator, and contraction primarily by acetylcholine. Despite the absence of c-Kit-positive ICC, nerve-muscle interaction can be accomplished likely by diffusion of neurotransmitters to the smooth muscle cells. The lack of c-Kit-positive ICC is related to an increase in the basal tone and spontaneous contractile activity. The presence of fibroblast-like ICC in Ws/Ws rats might represent immature ICC whose possible functions need further investigation.

Abstract
BACKGROUND Scabies is a common parasitic infestation and is very difficult to eradicate from institutions. Ivermectin is used extensively thanks to its efficacy and ease of use through oral administration; it was approved for the treatment of scabies in humans in 2001 in France. Most of the adverse effects noted with this drug have been seen during treatment of onchocerciasis and other filarial disease, but they are rare in the treatment of scabies. We report side effects with ivermectin in two elderly patients with scabies. CASES REPORT A 72-year-old man was referred for scabies and was treated with benzyl benzoate (Ascabiol) and ivermectin (200 microg/kg) in a single dose. Two days later, the patient presented abdominal pain and nausea. Laboratory tests revealed cytolysis tests for other causes of hepatitis were negative. Within two weeks, liver function had returned to normal. Hepatitis due to ivermectin was diagnosed. An 86-year-old woman hospitalised for scabies was treated with benzyl benzoate and a single dose of ivermectin (200 microg/kg). She developed sinus tachycardia and asthma 3 days later. Screening for embolic, cardiac and infectious origins was found. Toxicity of ivermectin was suspected. DISCUSSION Since the introduction of ivermectin for the treatment of scabies, reports of adverse events are rare although this drug can cause cardiac dysfunction and liver disease in other indications. In our cases, the causal relationship with ivermectin is probable and care must be taken, particularly in the elderly, the population in which this drug is probably most widely prescribed.

Abstract
INTRODUCTION Abrupt onset of papular lesions, with ulcero necrotic evolution could refers to many dermatitis. Febrile ulceronecrotic Mucha-Habermann disease is an unusual severe form of pityriasis lichenoides and varioliform acuta (PLEVA) characterized with ulceronecrotic eruption potentially associated with high fever and systemic symptoms leading to death. Lymphomatoid papulosis is a recurrent papulonodular eruption with an initial presentation close to PLEVA. While this disorder usually has a benign course, about 10% of the patients develop lymphoproliferative disorders such as CD30+ lymphoma. EXEGESIS The authors reported an acute form of PLEVA in a young man hospitalized in internal medicine unit with fever and ulcero-necrotic papulo-vesicular lesions. Treatment with tetracycline was successful. They also report a case of lymphomatoïd pustulosis that occurred in a 34 years old woman with an extensive nodulo-pustular eruption characterized by central necrosis and ulceration. Histopathological examination revealed CD30 lymphocytic infiltration leading to diagnosis. CONCLUSION Theses two dermatosis, uncommon and clinically similar, are both characterized with an unpredictable evolution that to be known by internist.

Abstract
This report describes the incidence, location and histopathological and immunohistochemical features of 30 canine meningiomas, of which 22 were intracranial, three were retrobulbar and five were located in the spinal canal. Nine types of meningioma were diagnosed: transitional (9), meningothelial (5), psammomatous (3), anaplastic (3), fibroblastic (2), angioblastic (2), papillary (2), microcystic (1) and meningiomas arising from the optic nerve (3). One of the optic nerve tumours had a granular cell component. All tumours were examined immunohistochemically with antibodies against vimentin, S100, neuron-specific enolase (NSE), cytokeratin (CK) and glial fibrillary acidic protein (GFAP). Vimentin was demonstrated in all tumours, and concentric whorls of cells showed more intense labelling than did bundles of fibroblastic cells. S100 labelling was detected in all tumours except a single angioblastic meningioma. The intensity of labelling for S100 was lower than that for vimentin, and bundles of fibroblastic cells showed particularly strong positivity. NSE labelling was highly variable, but most tumours displayed moderate positivity. CK expression was observed in five of the 30 meningiomas, and was stronger in areas of microcystic differentiation. Most of the tumours were GFAP-negative, but two fibroblastic meningiomas were strongly positive.

Abstract
BACKGROUND Pyogenic granuloma, or botryomycosis, occurring after minor injury or scratching with a septic implement, is a rapidly growing benign inflammatory vascular tumour, often involving the skin or mucous membrane. We report 5 unusual cases of pyogenic granuloma revealing fistula tracking to foreign bodies such as a pace-maker or orthopaedic material, and deep infectious sites with fistula. METHODS This retrospective study included 5 men of average age 72.2 years over a period of 22 years (between 1981 and 2003). Clinical images were recorded and a diagnosis of botryomycosis was confirmed in all patients by histological analysis. Four patients presented suppuration. The time from initial clinical signs to diagnosis, presence of traumatic events, screening for microscopic organisms, response to systemic antibiotic therapy, recurrence and clinical features of botriomycosis were analysed. RESULTS All patients presented botryomycosis with fistula and suppuration revealing deep bone infection and in one patient, pace maker infection. Complete resolution of the lesions occurred after excision of foreign material and prolonged systemic antibiotic therapy. CONCLUSION We report the first series of botryomycosis revealed by fistula and showing deep infectious disease. Pyogenic granuloma is a well-known but rarely reported dermatologic condition.

Abstract
INTRODUCTION Dermatomyositis is an inflammatory myopathy associated with an increased risk of mortality due to visceral involvement. Cutaneous involvement has no vital impact but considerably affects the quality of life of the patients and can resist to classical therapies. More treatment options are needed. We report here the case of three patients presenting resistant cutaneous lesions of dermatomyositis successfully treated with topical tacrolimus. OBSERVATIONS A dramatic cure of the lesions of the face and the hands and a moderate response of other areas were observed without adverse effects. CONCLUSION Tacrolimus is an immunosuppressive agent and topical tacrolimus is used for the treatment of atopic dermatitis and has been occasionally used to treat skin involvement of some systemic inflammatory diseases. Topical tacrolimus seems to be a good therapeutic alternative for resistant skin lesions of dermatomyositis. It could also be proposed as a first intention therapy because of its good tolerance.
