Abstract
Currently, only four molecules can be prescribed for amyotrophic lateral sclerosis (ALS), of which only one is approved worldwide for this indication, riluzole. Although progress in the therapeutic field remains unsatisfactory, we have to notice that genetics have undergone impressive improvements over the last three decades and, by extension, our knowledge of ALS cases linked to a pathogenic mutation that accounts for 10% of all cases (either sporadic or familiar) and is currently called hereditary ALS (hALS). In many neurological diseases treatment targeting pathogenic genes have significatively improved the natural profile of the disease: this is perfectly illustrated for familial amyloid neuropathy and spinal muscular atrophy. Because of these findings and the urgent need to find a cure for ALS, many trials have focused on familial ALS targeting the four most important genes linked to the disease: C9orf72, SOD1, TARDBP and FUS. We propose in this review an update on the perspectives of treatment that may be available in mid-term in hALS and will discuss in the last part the potential consequences for asymptomatic relatives of patients with a hALS and for ALS patients.

Abstract
BACKGROUND Amyotrophic lateral sclerosis (ALS) is a multifactorial fatal motoneuron disease without a cure. Ten percent of ALS cases can be pointed to a clear genetic cause, while the remaining 90% is classified as sporadic. Our study was aimed to uncover new connections within the ALS network through a bioinformatic approach, by which we identified C13orf18, recently named Pacer, as a new component of the autophagic machinery and potentially involved in ALS pathogenesis. METHODS Initially, we identified Pacer using a network-based bioinformatic analysis. Expression of Pacer was then investigated in vivo using spinal cord tissue from two ALS mouse models (SOD1G93A and TDP43A315T) and sporadic ALS patients. Mechanistic studies were performed in cell culture using the mouse motoneuron cell line NSC34. Loss of function of Pacer was achieved by knockdown using short-hairpin constructs. The effect of Pacer repression was investigated in the context of autophagy, SOD1 aggregation, and neuronal death. RESULTS Using an unbiased network-based approach, we integrated all available ALS data to identify new functional interactions involved in ALS pathogenesis. We found that Pacer associates to an ALS-specific subnetwork composed of components of the autophagy pathway, one of the main cellular processes affected in the disease. Interestingly, we found that Pacer levels are significantly reduced in spinal cord tissue from sporadic ALS patients and in tissues from two ALS mouse models. In vitro, Pacer deficiency lead to impaired autophagy and accumulation of ALS-associated protein aggregates, which correlated with the induction of cell death. CONCLUSIONS This study, therefore, identifies Pacer as a new regulator of proteostasis associated with ALS pathology.

Abstract
Background: Amyotrophic lateral sclerosis is the most frequent motor neuron disorders (MND) in adults. The role of genetic factors is worldwide accepted, and currently, more than 30 genes have been linked to this disease. Genetics was also the matter of numerous studies in distal hereditary motor neuropathies (dHMN). GARS is classically linked to a predominant dHMN and, until now, no mutation has been described in GARS in other MND. Case Report: We report the case of a 70-year-old woman who developed a classical bulbar ALS phenotype. Owing to his familial history of ALS, a genetic screening was performed excluding the main genes linked to ALS and revealing a heterozygous missense mutation in GARS gene with a high probability of pathogenicity. Conclusion: This first description of mutation in GARS in ALS, extends once more the genetic overlap between ALS and other MND.

Abstract
Amyotrophic lateral sclerosis (ALS) is a heterogenous motoneuronal neurodegenerative condition with a panel of phenotypes exhibiting different clinical patterns. Two compounds are currently available for the treatment of ALS but the majority of trials have failed to show a positive effect on prognosis. One of the explanations which could be put forward involves the way efficacy is evaluated: clinicians agree that the ALSFRS-revised scale used in all trials does not fit with highlighting a positive effect. So, the development and validation of new tools allowing a reliable assessment of ALS has become a key issue in clinical research. Over the last three years, two functional scales (the King's College and MiToS staging systems) have been proposed. These scales rely on two different approaches to ALS: an anatomical and prognostic concept, and loss of autonomy. Both scales propose five stages. We will discuss below the contribution of these two scales to clinical evaluation and the questions which remain to be resolved in the future.

Abstract
BACKGROUND Infantile haemangiomas (IH) are soft swellings of the skin that occur in 3-10% of infants. When haemangiomas occur in high-risk areas or when complications develop, active intervention is necessary. OBJECTIVE To update a Cochrane Review assessing the interventions for the management of IH in children. METHODS We searched for randomized controlled trials in CENTRAL, MEDLINE, Embase, LILACS, AMED, PsycINFO, CINAHL and six trials registers up to February 2017. We included 28 trials (1728 participants) assessing 12 interventions. RESULTS We downgraded evidence from high to moderate/low for issues related to risk of bias and imprecision. Oral propranolol (3 mg kg-1 daily) probably improves clinician-assessed clearance vs placebo [risk ratio (RR) 16·61, 95% confidence interval (CI) 4·22-65·34; moderate quality of evidence (QoE)]; we found no evidence of a difference in terms of serious adverse events (RR 1·05, 95% CI 0·33-3·39; low QoE). We found the chance of reduction of redness may be improved with topical timolol maleate (0·5% gel applied twice daily) when compared with placebo (RR 8·11, 95% CI 1·09-60·09; low QoE). We found no instances of bradycardia or hypotension for this comparison. CONCLUSIONS Our key results indicate that oral propranolol and topical timolol maleate are more beneficial than placebo in terms of clearance or other measures of resolution, or both, without an increase in harm.

Abstract
Delayed graft function (DGF) is a common complication after transplantation. Its incidence is increased among patients receiving a graft from an expanded-criteria donor. Urinary neutrophil gelatinase-associated lipocalin (uNGAL), an acute kidney injury marker, could in the first days after transplantation be an early marker of DGF. We collected urine samples from 38 renal transplant recipients on days 1, 3, 6, and 10 post-transplantation, and months 1 and 6 creatinine to determine uNGAL, serum creatinine, Cystatin C, and albumin/creatinine ratio. We divided the patients into 2 groups, based on whether they developed DGF. We observed that mean uNGAL concentrations, Cystatin C, serum creatinine, and albumin/creatinine ratio were significantly lower in the non-DGF cohort on all measured days. uNGAL at day 3 showed a positive correlation with serum creatinine at day 10 (R = 0.58; P < .00) and day 30 (R = 0.57; P = .016) as well as with the length of hospital stay (r = 0.47; P < .00). Receiver operating characteristic analyses performed to assess the potential of uNGAL to predict DGF showed an area under the curve for day 3 of uNGAL of 0.917 (confidence interval [CI], 0.79-1.00; P = .00), with an optimal cutoff level of 124 ng/mL, sensitivity of 80% (CI, 62%-97%), and specificity of 83% (62%-104%; P = .001). In the first days after transplantation, uNGAL could be an early marker of DGF, providing additional information to standard biomarkers and potentially helping clinicians to take early measures to mitigate DGF.

Abstract
Collisions with ski–lift cables are an important cause of death for grouse species living close to alpine ski resorts. As several biases may reduce the detection probability of bird carcasses, the mortality rates related to these collisions are generally underestimated. The possibility that injured birds may continue flying for some distance after striking cables represents a major source of error, known as crippling bias. Estimating the crippling losses resulting from birds dying far from the ski–lift corridors is difficult and it is usually assessed by systematic searches of carcasses on both sides of the ski–lifts. Using molecular tracking, we were able to demonstrate that a rock ptarmigan hen flew up to 600 m after striking a ski–lift cable, a distance preventing its detection by traditional carcasses surveys. Given the difficulty in conducting systematic searches over large areas surrounding the ski–lifts, only an experiment using radio–tagged birds would allow us to estimate the real mortality rate associated with cable collision.

Abstract
Schistosomes are gonochoric blood parasites with a complex life cycle responsible for a disease of considerable medical and veterinary importance in tropical and subtropical regions. Understanding the evolution of schistosome genetic diversity is clearly of fundamental importance to interpreting schistosomiasis epidemiology and disease transmission patterns of this parasite. In this article, we investigated the putative role of the host immune system in the selection of male genetic diversity. We demonstrated the link between genetic dissimilarity and the protective effect among male worms. We then compared the proteomes of three male clones with different genotypes and differing by their capacity to protect against reinfection. The identified differences correspond mainly to antigens known or supposed to be involved in the induction of protective immunity. These results underline the role played by host immune system in the selection of schistosome genetic diversity that is linked to antigenic diversity. We discuss the evolutionary consequences in the context of schistosome infection.

Abstract
Schistosomes represent a unique animal model for comparative analyses of monogamy. Indeed, schistosomes are classified at the lowest taxonomical level of monogamous species and lack complex social interactions, which could alter our understanding of their unusual mating system. Elements discussed here include the fact that monogamy in schistosomes could be an ancestral state between hermaphroditism and polygyny or polygynandry and the occurrence of mate changes. In addition, hypotheses are proposed to explain monogamy in schistosomes (e.g. female dispersion, the need for paternal care, oviposition site limitation or aggressiveness, and mate guarding). We also propose future experimental and analytical approaches to improve our understanding of the schistosomes' mating system.

Abstract
Prognosis of differentiated thyroid cancer is favorable in the majority of cases. However, distant metastases occur in 10-15% of cases, predominantly in lungs and bones, especially in older patients exhibiting poorly differentiated forms or advanced stages. We report a case history of Hürthle cell thyroid carcinoma metastasized to the sigmoid colon. To the best of our knowledge, this location has never been described before. This case history illustrates the difficulties of diagnosis and treatment in patients whose metastases do not concentrate radioiodine. The interest of different imaging modalities, including fluoro-deoxy-glucose positron emission tomography scan and somatostatin receptor scintigraphy, is discussed.

Abstract
AIMS AND METHODS A study of 350 HIV+ patients in our region showed that 16% suffered from hypothyroidism. Twenty-two HIV+ hypothyroid patients (10 with subclinical hypothyroidism, 12 with low FT4 levels (LT4) (confirmed by a dialysis equilibrium assay) and 22 HIV+ euthyroid controls receiving highly active anti-retroviral therapy were included in an additional study. RESULTS No goiter or anti-thyroid antibodies were detected. Use of stavudine was more frequent in the LT4 subgroup (p < 0.01) and subclinical hypothyroidism group (p = 0.04). Use of didanosine (OR, 12.5, p < 0.01) and ritonavir (OR, 33.0, p < 0.01) was more frequent in the LT4 subgroup, with a greater didanosine cumulative dose (616.7 mg [180.0, 1,260.0] vs. 263.7 [63.0, 948.0], p = 0.01). Reverse T3, binding protein levels, the TSH response to thyrotropin-releasing hormone, urinary iodine, plasma selenium and thiocyanate levels did not differ. IFNgamma levels were lower in the subclinical hypothyroidism group (pg/ml) (9.1 [0.0, 22.7] vs. 19.5 [0.0, 40.9], p = 0.03). CONCLUSION None of the investigated mechanisms are able to explain the occurrence of hypothyroidism in HIV patients receiving highly active anti-retroviral therapy except the anti-retroviral treatment. In light of the absence of autoimmunity, the normal adenohypophysis and thyroid responses to thyrotropin-releasing hormone, central hypothyroidism is suspected and could explain LT4 and high TSH levels. Underlying mechanisms need further exploration.

Abstract
INTRODUCTION A primary antiphospholipid syndrome is a very rare cause of adrenal haemorrhage. OBSERVATION A 51 year-old man presented with a unilateral adrenal haemorrhage, enhanced by the prescription of Synacthène during the 4 days that preceded. There was no adrenal deficiency but the immunological control revealed the presence of anti-phospholipid antibodies. After 2 years of follow-up, adrenal controls have not shown any underlying tumour or endocrine insufficiency. COMMENTS Adrenal involvement is described in the anti-phospholipid syndrome and may present in the form of adrenal deficiency in the case of occasionally only microscopic bilateral haemorrhages. Furthermore, Synacthène is known to induce adrenal haemorrhages although this complication remains rare. Moreover, any unilateral adrenal haemorrhage requires subsequent follow-up for several months or even years in order to eliminate any underlying tumour and to control the absence of any adrenal deficiency if the involvement is bilateral.

Abstract
The aim of this study was to determine the prevalence of celiac disease (CD) markers in a French cohort of 84 children type 1 diabetics. Detection of antitransglutaminase (AtTG), antiendomysium (AEA) and antigliadin (AGA) antibodies was performed. Group 1 included 81 (96.4%) diabetic patients with negative antibodies. Group 2 included 3 patients (3.6%) with positive serological markers: 1 AGA-AEA-AtTG and 1 AEA-AtTG with proved histological diagnosis and 1 AGA positive with negative histology. No statistically significant difference was observed between the groups with regard to age, duration of diabetes, familial target stature, and ratios Height/Age and Weight/Height. Presence of CD serological markers was related to a lower level of HbA1c. Prevalence of CD serological markers is important in this French cohort but lower than other countries.

Abstract
This case report highlights the difficulty of diagnosing tuberculous sinusitis in the absence of pulmonary foci. Although extrapulmonary localisations of tuberculosis are rare in immunocompetent patients, it is important to consider this diagnosis, since therapeutic delay usually results in an unfavourable outcome. Acid-fast bacilli are sometimes difficult to detect in pathological specimens. Consequently, the diagnosis is usually based on the following criteria: (i) the absence of clinical response to usual antibiotics, (ii) the presence of caseous granulomatous inflammatory lesion on histopathology, and (iii) identification of Mycobacterium tuberculosis by the polymerase chain reaction assay confirmed by bacteriological culture. The diagnosis of tuberculosis is finally confirmed by the efficacy of antituberculous treatment. The differential diagnosis is Wegener's disease.

Abstract
We report the case of a 44-year-old obese diabetic woman admitted for fever. Blood cultures grew Staphylococcus Aureus and antibiotherapy was started. Iliac abscess was diagnosed and surgical drainage done. Clinical evolution was marked by metastatic dissemination: sacroiliac osteolysis, right shoulder osteoarthritis, spondylitis of the third lumbar vertebra and pulmonary localizations. This case-report shows diagnosis and treatment difficulties of an iliac muscle abscess with metastatic localization in a diabetic patient.

Abstract
Magnetic resonance arthrography is superior to other imaging techniques in evaluation of the glenohumeral joint. Normal variants that can be diagnostic pitfalls include the anterosuperior sublabral foramen, the Buford complex, and hyaline cartilage under the labrum. Anteroinferior dislocation is the most frequent cause of anterior glenohumeral instability and produces a constellation of lesions (anteroinferior labral tear, classic and osseous Bankart lesions, Hill-Sachs lesion). Variants of anteroinferior labral tears include anterior labroligamentous periosteal sleeve avulsion and glenoid labral articular disruption. Anterior glenohumeral instability can also involve tears of the anterior or anterosuperior labrum or the glenohumeral ligaments. Posterior glenohumeral instability can involve a posterior labral tear, posterior capsular stripping or laxity; fracture, erosion, or sclerosis and ectopic ossification of the posterior glenoid fossa; reverse Hill-Sachs lesion; McLaughlin fracture; or posterosuperior glenoid impingement. Superior labral anterior and posterior lesions involve the superior labrum with varying degrees of biceps tendon involvement.

Abstract
The World Health Organization has designated the teaching of otitis media management skills a "priority" status. Effective treatment of ear disease requires that the physician be both informationally educated as well as physically trained to use otoscopy. Little is known about how well this education can be provided in a short time and in a foreign country. To more objectively assess teaching effect, results of an education session for rural Mexican pediatric primary-care providers who were given an intensive otitis media lecture and otoscopy skills workshop in 1990 were evaluated. To test immediate cognitive impact, an anonymous written examination was given both before and after the teaching session. Average test scores after the educational sessions improved 24% (p < 0.001) over baseline scores before the sessions. To evaluate long-term impact on clinical practice, a follow-up telephone survey 2 years later was conducted. The use of an otoscope to diagnose otitis media had increased from 40% to 93% of respondents. We conclude that pediatric primary-care providers in rural Mexico possess a baseline level of knowledge about otitis media that can be significantly enhanced with one educational session. Further, this teaching effort produces an impact on practice pattern that lasts at least 2 years.
