- Abstract
Introduction: Few studies have evaluated the promising role of
18 F-fluoro-2-deoxy-D-glucose positron emission tomography (PET) and PET/computed tomography FDG PET/CT in evaluating and monitoring treatment response in patients with lymph node tuberculosis (LNTB). The aim of this clinical investigation was to assess the clinical usefulness of FDG PET/CT for initial tuberculosis staging and to determine the prognostic value of the decrease of18 F-FDG uptake during antibiotic treatment in LNTB patients., Methods: We retrospectively reviewed 18 cases of LNTB admitted at a single center from 2004 to 2014. Medical records of patients who underwent two FDG PET/CT (>6 months interval), at initial staging and at the end of therapy were reviewed to determine the impact of FDG PET/CT on initial management of LNTB and response to therapy. Statistical analysis was performed using linear mixed-effects model., Results: Thirteen cases of disseminated LNTB and five cases of localized LNTB were included in the study. Initial FDG PET/CT allowed guided biopsy for initial diagnosis in 5 patients and identified unknown extra-LN TB sites in 9 patients. Visual analysis follow-up of FDG PET/CT showed a complete metabolic response in 9/18 patients (all of whom were cured), a partial response in 7/18 (5 of whom were cured) and no response in 2/18 (all of whom were not cured). The semi-quantitative evaluation of 18F-FDG intensity decrease based on the maximum standardized uptake value (SUVmax), compared to targeted estimated decrease allowed to predict correctly a complete response to treatment in 14/18 cases., Conclusion: FDG PET/CT allows an accurate pre-therapeutic mapping of LNTB and helps for early TB confirmation. The SUVmax follow up is a potential tool for monitoring the treatment response., (Copyright © 2017 Elsevier Inc. All rights reserved.)- Published

- Abstract
Objective: Staphylococcus lugdunensis is a coagulase-negative staphylococcus that displays an unusually high virulence rate close to that of Staphylococcus aureus. It also shares phenotypic properties with S. aureus and several studies found putative virulence factors. The objective of the study was to describe the clinical manifestations of S. lugdunensis infections and investigate putative virulence factors., Method: We conducted a prospective study from November 2013 to March 2016 at the University Hospital of Strasbourg. Putative virulence factors were investigated by clumping factor detection, screening for proteolytic activity, and sequence analysis using tandem nano-liquid chromatography-mass spectrometry., Results: In total, 347 positive samples for S. lugdunensis were collected, of which 129 (37.2%) were from confirmed cases of S. lugdunensis infection. Eighty-one of these 129 patients were included in the study. Bone and prosthetic joints (PJI) were the most frequent sites of infection (n=28; 34.6%) followed by skin and soft tissues (n=23; 28.4%). We identified and purified a novel protease secreted by 50 samples (61.7%), most frequently associated with samples from deep infections and PJI (pr 0.97 and pr 0.91, respectively). Protease peptide sequencing by nano-liquid chromatography-mass spectrometry revealed a novel protease bearing 62.42% identity with ShpI, a metalloprotease secreted by Staphylococcus hyicus., Conclusion: This study confirms the pathogenicity of S. lugdunensis, particularly in bone and PJI. We also identified a novel metalloprotease called lugdulysin that may contribute to virulence., (Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases.

- Abstract
Schinzel-Giedion syndrome (SGS, MIM #269150) is a rare syndrome characterized by severe intellectual disability, typical facial gestalt, hypertrichosis and multiple congenital malformations including skeletal, genitourinary, renal and cardiac abnormalities. The prognosis of SGS is very severe and death occurs generally within a few years after birth. In 2002, we reported 2 children with SGS with a follow-up of 3 years. They presented a very similar and particular phenotype associating distinctive facial gestalt, severe developmental delay, megacalycosis, progressive neurodegeneration, alacrimi, corneal hypoesthesia and deafness. Furthermore, temporal bone imaging revealed a tuning-fork malformation of the stapes. In 2010, Hoischen et al. identified in SGS patients pathogenic heterozygous de novo mutations in SETBP1. We sequenced SETBP1 in our patients and found the previously reported c.2608G>A (p.Gly870Ser) mutation in both children. Since 2002, one of our patients died at 6 years old and the other patient is still alive at 15 years old. Such a life expectancy has never been reported so far. We describe herein the follow up of the 2 children during 6 and 15 years respectively. This article gives further evidence of the implication of SETBP1 as the major gene of SGS, and reports the previously unseen natural evolution of the disease in a 15 years old patient., (Copyright © 2015.

- Abstract
Objectives: We had for objectives: i) to evaluate the accuracy of serologic testing for Lyme borreliosis performed in a private medical laboratory (PML); ii) to evaluate the impact of these tests on the practices of infectious diseases specialists (IDS)., Patients and Method: This study was performed in two steps: i) retrospective study of patients followed in a university hospital infectious diseases outpatient clinic for suspected Lyme borreliosis, tested (ELISA and Western blot) by both the PML and the National Reference Center (NRC); ii) national survey on IDS practices concerning patients consulting for suspected Lyme borreliosis., Results: Between July 2008 and July 2011, 128 patients consulting for suspected Lyme borreliosis were tested by both laboratories. Serological tests came back positive in 91% of cases from the PML versus 8% of cases from the NRC. Lyme borreliosis was the IDS's final diagnosis for 3.6% of patients. The survey on practices revealed that: i) the modal duration of consultation for suspected Lyme borreliosis was 30-60 minutes; ii) for 33% of patients, serologic test results performed at the PML were the only reason to suspect Lyme borreliosis; iii) 60% of patients had no indication for antibiotics., Conclusion: The serological test performed in the PML were positive most of the time, but were not confirmed by tests performed at the NRC. This discrepancy lead to multiple and prolonged consultations in infectious diseases clinics, and discordance in the indications for antibiotics., (Copyright © 2014 Elsevier Masson SAS.

- Abstract
Objectives: Immunoglobulin (Ig) deficiency is a well-known risk factor for Streptococcus pneumoniae or Haemophilus influenzae infections and noteworthy invasive diseases. However, the proportion of these deficiencies in cases of invasive disease is unknown. The objective of this study was to evaluate the rate of Ig deficiency in cases of invasive disease., Methods: A prospective study was conducted from January 2008 to October 2010 in two French hospitals. Measurement of Ig levels was carried out in patients hospitalized for invasive diseases., Results: A total of 119 patients were enrolled in the study, with nine cases of H. influenzae and 110 cases of S. pneumoniae invasive disease. There were 18 cases of meningitis, 79 of invasive pneumonia, and 22 other invasive diseases. Forty-five patients (37.8%) had an Ig abnormality, 37 of whom had an Ig deficiency (20 IgG <6g/l, four isolated IgA <0.7g/l, and 13 isolated IgM <0.5g/l), while eight had an elevated monoclonal paraprotein. Nineteen of these 45 patients had a clearly defined Ig abnormality, with five primary deficiencies (three common variable immunodeficiencies and two complete IgA deficiencies) and 14 secondary deficiencies, mainly lymphoproliferative disorders. All these deficiencies were either not known or not substituted., Conclusions: Humoral deficiency is frequent in patients with S. pneumoniae or H. influenzae invasive disease and Ig dosage should be proposed systematically after such infections., (Copyright © 2013 The Authors.

- Abstract
We report the prenatal diagnosis of a 12q22q23.2 de novo interstitial deletion performed by array based comparative genomic hybridization (array CGH) in a fetus with cystic hygroma colli, intrauterine growth retardation, microcephaly and micrognathism. Haploinsufficiency for insuline-like growth factor 1 gene (IGF1), which is mapped in the deleted region, is suggested because of its implication in prenatal and postnatal growth and in neuronal maturation. This case demonstrates the contribution of array CGH in prenatal diagnosis for detecting small unbalanced chromosomal abnormalities in malformed fetuses and, subsequently, for genetic counselling., (Copyright © 2012 Elsevier Masson SAS.

- Abstract
Context: An outbreak of scabies occurred in the geriatric department of the Strasbourg University Hospital in September 2005. The index case presented with hyperkeratosic scabies, an extremely contagious form. The epidemic spread to several wards and pavilions and also contaminated healthcare staff and patient's families., Objective: Our objective was to describe the outbreak, its progression, and the measures taken to eradicate it., Methodology: All healthcare workers, patients, and families affected in the outbreak were retrospectively studied, using medical prescriptions recorded by the hospital pharmacy, listings established by the occupational health department, and patient files., Results: Two epidemic waves were recorded, between August 31 and December 16, 2005, affecting 51 patients and staff members in the geriatric department, with a total of 58 episodes of scabies, seven of which were recurrences. Three main measures were taken to eradicate the epidemic: setting up of "contact" isolation precautions, information for the affected individuals, and treatment of the infected patients associated to mass treatment of contact cases. The mass treatment was widely applied, involving 490 patients and 592 caregivers. All of these measures successfully curtailed the outbreak in 3 months., Conclusion: Rapid and radical action is essential to prevent extension of scabies within a community., (Copyright © 2010 Elsevier Masson SAS.

- Abstract
Introduction: HIV patients have a high rate of infectious complications. Vaccination, though less efficient in case of severe immunosuppression, can prevent some of these infections. Since 2006, new vaccine recommendations have been elaborated in France. We studied the vaccine status of HIV+ patients for influenza, Streptococcus pneumoniae, tetanus, and hepatitis A and B among an alsatian HIV+ population., Patients and Methods: From August 20, 2007 to September 15, 2007, HIV patients of the Alsace HIV center (COREVIH) were included in a prospective study, screening demographic, medical, immunovirological, and vaccination data., Results: Three hundred and thirty-one patients were included, 49% of whom were asymptomatic, 29% symptomatic without AIDS, 18% at AIDS stage, and no documentation for 4%. Seventy-one patients (21.4%) were vaccinated against influenza, 11 (3.3%) against Streptococcus pneumoniae, 34 against HAV (only 16.3% of patients with a negative test before), 120 against HBV (60% of patients with no serological markers before), and 186 (56.2%) against tetanus. The most frequent reasons for non-vaccination were non-proposal by physicians, lack of expected effectiveness, and fear of an immunovirological adverse effect., Conclusion: Vaccination coverage for recommended vaccines of HIV infected people remains at a low level and appears sometimes inferior to the rates reached among the general French population. It is necessary to inform prescribers and HIV positive patients about the interest of vaccination., (Copyright © 2010 Elsevier Masson SAS. All rights reserved.)

- Abstract
We report the case of a 27-year-old man presenting with a hepatic abscess and hereditary hemorrhagic telangiectasia (HHT). The association between HHT and an infectious disease seemed to be induced by arteriovenous malformations and maybe also by a deficit of polymorphonuclear cells, a monocyte oxidative burst and phagocytosis. This diagnosis should be suggested in case of serious infections in young patients. Prevention is based on screening for and destroying infection, antibioprophylaxis and embolization of arteriovenous malformations.

- Abstract
Objectives: Streptococcus agalactiae (Group B streptococcus) is a major cause of invasive diseases in non-pregnant adults, particularly in the elderly and those with underlying conditions. We describe these conditions and clinical characteristics of patients followed in our teaching hospital., Methods: We retrospectively reviewed clinical records of 64 patients with S. agalactiae-related invasive infection, hospitalized between January 1997 and January 2006., Results: The mean age of patients was 59 (+/-17 years). The H:F sex ratio was 1.06. At least one underlying condition was found in 90.6%. Diabetes mellitus (43.7%), peripheral vascular disease (34.4%), myocardial ischemia (20.3%) and malignant neoplasms (20.3%) were among the most frequent conditions. The mean index of comorbidity (Charlson) was 2.5 (+/-2). Common clinical manifestations included infection of the urinary tract (32.8%), skin and soft-tissue (25%), and osteoarthritis (21.9%). Bacteremia occurred in 31.2% with no identified source in 2 patients. During the first month, 2 cases of endocarditis, 1 case of meningitis, and 4 deaths occurred., Conclusion: We confirm the importance of underlying diseases in the emergence of S. agalactiae infections.

- Abstract
Purpose: Staphylococcus aureus is the first agent responsible for nosocomial bacteremia in France. About 40% of the strains are resistant to methicillin (MRSA). The epidemiology of these infections has changed in the last fifteen years whereas therapeutics options have slightly progressed., Current Knowledge and Key Points: Hospital-acquired MRSA bacteremia are more and more frequent while community-acquired strains recently appeared. Factors influencing the emergence of these infections were identified thanks to numerous clinical studies, as well as patients risk factors for developing these infections and their complications. At the same time, intermediate sensitive and resistant MRSA strains to glycopeptides appeared. Conversely, the best antibiotic strategy is still unclear in absence of good clinical studies. The interest of antibiotics combinations and of glycopeptides serum-concentrations control is still a matter of debate. Finally, the number of new active molecules remains limited., Perspectives: The frequency and severity of MRSA bacteremia are quite worrying in our country. The epidemiology of these infections must be known by every clinicians in order to prevent them. The therapeutic strategy has to be better define and need for new anti-infectious agents is critic.

- Abstract
The post therapeutic follow-up of Lyme borreliosis is managed according to clinical and serological data. The evolution of antibody rates is such that it doesn't constitute the best element to rely on for follow-up. Indeed, after a sometimes transitory increase of this rate during or after antibiotherapy, the decrease is very slow, sometimes several months, and often incomplete. The follow-up should thus be made according to clinical symptoms and their resolution. Resolution of some but not all symptoms must lead to discussing two options. The first is that of administrating a complementary antibiotherapy with a different mode of action than the first antibiotic used. The second is that this may be due to recontamination, especially in highly endemic zones, given that antibodies present have no protecting effect. In this case, a new antibiotherapy must of course be initiated.

Background: This study had for aim to describe the clinical aspects and favoring factors of mucosal Leishmaniasis in an Amazonian population of 30,000 habitants in Guajara-Mirim (Rondonia-Brazil)., Material and Method: A descriptive study was made of 16 patients with mucosal Leishmaniasis among 170 patients infected by Leishmania. Inclusion criteria were a mucosal lesion and positivity of direct microscopic examination. The patients were investigated retrospectively., Results: Patients with mucosal Leishmaniasis were young and mostly male The absence of treatment and the number of cutaneous lesions were probably responsible for the mucosal form, as well as the host immune response and maybe, the parasite species or vector characteristics., Conclusion: The mucosal form of leishmaniasis affects more often young male patients and this form must be detected early to avoid destructing lesions.

- Abstract
Foreword: Clostridium difficile associated diarrhea (CDAD) accounts for 25% of all cases of diarrhea occurring in hospital. Infectious diseases departments are considered as presenting with an important risk of CDAD because of the large quantity of antibiotics used., Objectives and Method: The authors made a prospective study in the first 6 months of 2001, in order to identify the risk factors of CDAD in their department. One hundred and fifty-two patients hospitalized for at least 6 days were included in this study. The studied factors were: age, mean number of days of hospitalization (MDH), antibiotic therapy, WHO scale of reduced mobility of patients, recent hospitalization (less than 3 months before)., Results: MDH was 36 (IC95%: 23-48). Beta-lactam antibiotics were found as significant risk factors, as reported in the literature. However, age and a recent hospitalization were not related to the CDAD as described in the literature. A reduced mobility of patients was identified as a significant risk factor for developing a CDAD in our department.

- Abstract
Objective: To insist on the difficulty of the antenatal diagnosis of digestive duplications, to show the importance of a complete malformative screening, and the need for immediate management at birth., Material and Methods: A cystic duplication of the tongue, a duplication, abdomino-thoracic transdiaphragmatic, and a duplication of the small bowel are described and compared with cases previously reported in th literature., Results: Antenatal evacuation puncture of a duplication of the tongue must be reserved for exceptional situations. Foregut duplications are often associated with other malformations. The duplication of the small intestine can exceptionally expose to a mechanical complication, mostly during the postnatal period, which may require emergency surgery., Conclusion: Duplications of the alimentary tract should be detectable on prenatal ultrasound examination. A complete antenatal malformative screening is required and in utero transfer is warranted because emergency surgery may be required.

- Abstract
Neurological complications following rubella are only rarely encountered. We report a case of isolated myelitis. A 44-year-old healthy female suffered from an erythematous macular rash which rapidly cleared. However, the following days, dysuria initiated hospitalization. On admission, she was febrile but alert and in normal mental status. General physical examination was quite unremarkable. Four days later, she suffered from acute urinary retention, fecal retention and vaginal hypoesthesia. Routine laboratory data, chest skull and spinal column X-rays were unremarkable. The sterile cerebrospinal fluid contained 30 lymphocytes/mm3, 0.48 g/ml of protein but normal amount of glucose. Rubella antibody titers showed a significant elevation and specific IgM were detected by immunocapture. Improvement was rapid and recovery was uneventful except a mild vaginal hypoesthesia that persisted 5 weeks later. Diffuse myelitis occurring shortly after rubella vaccination have also been described. The immunopathological mechanisms by which involvement of the nervous system occurs is far from clear. Little is known about the pathogenesis of post-vaccination myelitis and although the mecanism of sensitization and the specific neural antigens are not known, post-infectious and post-vaccinal myelitis are thought to share a common pathogenic basis.

- Abstract
Background: Nephrotic syndrome is known to be associated with thrombosis but rarely of cerebral vessels., Case Report: A 3-year old child with steroid-dependent nephrotic syndrome was hospitalized for drowziness followed by a left hemiparesis. The CTscan showed a superior sagittal sinus thrombosis. The child completely recovered after treatment by low molecular weight heparin (LMWH)., Conclusion: LMWH could be used for preventing and/or treating thrombosis associated with nephrotic syndrome. Nevertheless, controlled studies are necessary for assessing its efficacy and absence of risk in children.

- Abstract
Henoch-Schönlein purpura is a vasculitis usually with a benign course. Abdominal symptoms occur in 70% of cases, with possible intussusception or intestinal perforation. There is no clear evidence of the efficacy of a treatment in complicated cases of Henoch-Schönlein purpura. Corticosteroids improve abdominal pain but they do not have any effect on renal involvement or prevention of relapses. Intravenous immunoglobulins have been efficient in some cases with recurrent abdominal symptoms or progressive renal lesions. We report the case of a 19-year-old patient with severe abdominal involvement and early renal manifestations of Henoch-Schönlein disease, rapid and sustained improvement was obtained by intravenous immunoglobulins given during 48 hours.

- Abstract
The authors report their experience of cerebral magnetic résonance imaging (MRI) in the neonatal period. MRI offers many advantages compared to CT scan or ultrasonography in the study of malformations, tumors, infections and anoxic-ischemic brain injury. However, MRI is limited by the duration of the examination the need for total immobility which is achieved in the neonate via administration of chloral hydrate, and lack of accessibility. MRI is a non invasive method for following in vivo brain development during infancy.

- Abstract
This is a retrospective study of the records of 17 patients who suffered from infectious endocarditis with positive blood cultures, and concerns the possibilities of predicting immediate infectious signs in patients:--by testing each of the antibiotics used for the minimal inhibitory concentration;--by determining the peak of the serum bactericidal activity of patients. All the patients were under observation, as outpatients, for more than a year and proved completely cured of their infectious endocarditis. A satisfactory minimal inhibitory concentration does not necessarily prevent an infectious evolution in the immediate future. The determination of the peak serum bactericidal activity does not reflect faithfully and instantaneously the anti-infectious action of the treatment; this is shown by the excellent and rapid evolution 13 times out 20 although serum bactericidal activity was considered insufficient (less than 1/8). This level of 1/8 is not a guarantee of therapeutic efficiency. Finally the antiinfectious treatment has been, in the majority of cases, determined by clinical signs and in very few cases by serum bactericidal activity results.

- Abstract
Peritoneal mesothelioma ranks second in frequency after pleural mesothelioma. A well-established clinical entity since 1960, mesothelioma is increasingly frequent due to improvements in diagnostic methods and to the fairly wide industrial use of asbestos, a well-known carcinogenic substance for mesothelial cells. The diagnosis of malignant peritoneal mesothelioma rests on a corpus of convergent data. Treatment consists of surgery combined with radiotherapy and chemotherapy. The mean survival from the time of diagnosis is 8-10 months.

- Abstract
After presenting the case of a 70 year old woman who presented a massive mesenteric infarction as a result of non-occlusive intestinal ischaemia ( NOII ), the authors review the principal features of this particular form of intestinal ischaemia. This condition is seen principally in elderly people with a syndrome of low cardiac output, resulting in marked mesenteric vasoconstriction. It is a complication of either severe decompensated heart disease treated with digitaloids or to a state of hypovolaemic or septic shock. The diagnosis of NOII should be suggested by the combination of abdominal signs with a state of shock and/or treated heart disease. The diagnosis is confirmed by selective mesenteric arteriography which reveals a patent but spastic vessel. The treatment is initially medical, consisting of the correction of haemodynamic disturbances and the in situ injection of vasodilator products, which may need to be completed by a surgical operation. However, the prognosis of NOII remains serious, particularly because of the frequent delay in making the diagnosis.
