Multidisciplinary team meeting for complex bone and joint infections diagnosis: The PHICTOS study.

BACKGROUND: In France, the most severe bone and joint infections (BJI), called "complex" (CBJI), are assessed in a multidisciplinary team meeting (MTM) in a reference center. However, the definition of CBJI, drawn up by the Health Ministry, is not consensual between physicians. The objective was to estimate the agreement for CBJI classification. METHODS: Initially, five experts from one MTM classified twice, one-month apart, 24 cases as non-BJI, simple BJI or CBJI, using the complete medical record. Secondly, six MTMs classified the same cases using standardized information. Agreements were estimated using Fleiss and Cohen kappa (κ) coefficients. RESULTS: Inter-expert agreement during one MTM was moderate (κ=0.49), and fair (κ=0.23) when the four non-BJIs were excluded. Intra-expert agreement was moderate (κ=0.50, range 0.27-0.90), not improved with experience. The overall inter-MTM agreement was moderate (κ=0.58), it was better between MTMs with professor (κ=0.65) than without (κ=0.51) and with longer median time per case (κ=0.60) than shorter (κ=0.47). When the four non-BJIs were excluded, the overall agreement decreased (κ=0.40). CONCLUSION: The first step confirmed the heterogeneity of CBJI classification between experts. The seemingly better inter-MTM than inter-expert agreement could be an argument in favour of MTMs, which are moreover a privileged place to enhance expertise. Further studies are needed to assess these results as well as the quality of care and medico-economic outcomes after a MTM.

[Uncommon cutaneous presentation of visceral Leishmaniasis associated with HIV]. / Manifestations cutanées inhabituelles au cours d'une leishmaniose viscérale associée au VIH.

BACKGROUND: Visceral leishmaniasis is not normally expressed in skin. Herein, we describe the case of an HIV-positive patient who developed two unusual skin manifestations during an episode of visceral leishmaniasis. PATIENTS AND METHODS: A 48-year-old female patient consulted initially for infiltrated purpura of all four limbs. Skin biopsy revealed leukocytoclastic vasculitis with Leishman-Donovan bodies. Laboratory tests showed medullary, splenic, gastric and colic involvement, suggesting systemic disease, and enabling visceral leishmaniasis to be diagnosed. Two years later, despite prolonged treatment, the patient presented maculopapular exanthema, and histology revealed persistent Leishman-Donovan bodies. DISCUSSION: We report herein an association of two rare skin manifestations in an HIV-positive patient with visceral leishmaniasis: infiltrated purpura and maculopapular exanthema. However, the underlying mechanisms remain hypothetical. The initial leukocytoclastic exanthema could be secondary to either polyclonal hypergammaglobulinaemia or to IgA deposits, or possibly to mechanical impairment of blood vessels by the actual parasite. The maculopapular exanthema occurring later raised the possibility of post-Kala-Azar leishmaniasis due to blood-borne dissemination in an anergic subject or perhaps even immune reconstitution inflammatory syndrome.

A survey on the use of gentamicin in infective endocarditis.

US and European guidelines recommend a daily divided gentamicin dose (3 mg/kg in two or three equally divided doses) for the treatment of infective endocarditis caused by staphylococci or enterococci, but once-daily dosing (3 mg/kg/day) is recommended for streptococcal endocarditis. However, studies have recommended the use of higher doses of gentamicin (4 or ≥5 mg/kg/day) administered once-daily. A survey was conducted in France by mailing a questionnaire to the 595 members of the French Infectious Disease Society regarding their gentamicin prescription patterns in infective endocarditis, focusing on the dosing regimen. The survey was answered by 137 physicians (23%). The proportions of physicians following guideline-based regimens were similar for each organism (30.9%, 38.8%, and 39.4% for staphylococci, enterococci, and streptococci, respectively [p=0.26]). In contrast, the proportions of physicians following literature-based regimens were significantly different for each organism (59.6%, 42.5%, and 27.7% for staphylococci, enterococci, and streptococci, respectively [p<0.001]). The number of years practicing and the type of practice (university vs. non-university hospital) did not influence the gentamicin dose or regimen. Although adherence to published guidelines for gentamicin administration in patients with infective endocarditis was poor, a large proportion of physicians who did not follow those guidelines used literature-based regimens.

[Inflammatory myopathy following acute meningoccemia in a properdin-deficient patient: A case report]. / Myopathie inflammatoire post-méningococcémie aiguë chez un patient présentant un déficit en properdine : à propos d'un cas.

INTRODUCTION: Myalgia is a classical sign in invasive meningococcal diseases (IMD), but severe and persistent myalgia following an IMD have never been reported to date. CASE REPORT: A 20-year-old man presented with purpura fulminans and meningitis caused by Neisseria meningitidis serogroup Y, revealing properdin deficiency. Although meningitis symptoms improved after antibiotherapy, initial myalgia of the lower limbs increased, associated with mild rhabdomyolysis. Magnetic resonance imaging (MRI) revealed an increased STIR (Short TI inversion recovery) signal of both quadriceps muscles, without abscess. After exclusion of other causes of myopathy, a post-infectious myositis was diagnosed. A four-week course of corticosteroids led to dramatic improvement. CONCLUSION: Post-infectious inflammatory myopathy should be suspected in case of severe and persistent myalgia associated with rhabdomyolysis following an IMD, after exclusion of pyomyositis especially. A short course of corticosteroids seems to be effective.

Optimal duration of antibiotic therapy in vertebral osteomyelitis.

OBJECTIVES: To compare the risk of relapse of vertebral osteomyelitis (VO), according to the duration of antibiotic therapy (< or =6 weeks versus >6 weeks). METHODS: We performed a 10-year retrospective study to assess the risk of VO relapse and to verify that this risk was not enhanced in patients who received 6 weeks of antibiotic therapy (Group 1) as compared with those who received a longer treatment (Group 2). VO was diagnosed based on clinical manifestations, magnetic resonance imaging and/or computed tomography findings, and isolation of a pyogenic organism in blood cultures and/or a discovertebral biopsy. Relapse was diagnosed based on isolation of the same organism in blood cultures and/or a discovertebral biopsy. Outcome was evaluated 6 months post-treatment and in December 2004. RESULTS: Group 1 included 36 patients (mean age, 58 +/- 15 years) and Group 2 included 84 patients (mean age, 67 +/- 15 years) (P = 0.003). Clinical data and microorganisms were comparable in the 2 groups. In the first 6 months, 6 (5%) patients died (Group 1, n = 2; Group 2, n = 4), and 5 (4%) in Group 2 relapsed, 2 with recurrent VO and 3 with recurrent bacteremia. In 2004, 91 patients were evaluated (mean follow-up, 40.6 +/- 31 months): 77 (85%) were cured, 13 (14%) died (Group 1, n = 3; Group 2, n = 10), 1 had VO due to a different microorganism (Group 2), and no long-term relapses occurred. CONCLUSION: Our results suggest that antibiotic therapy of VO could be safely shortened to 6 weeks without enhancing the risk of relapse.

Legionnaire's pneumonia: is there really an interstitial disease?

OBJECTIVE: Legionella pneumonia is usually classified as "atypical pneumonia", which suggests a predominance of interstitial patterns in chest X-rays. Based on a selection of recent clinical cases and a brief review of the literature, the aim of the study is to clarify, how far the actual radiological findings would be consistent with these expectations. PATIENTS AND METHODS: A retrospective analysis of 18 epidemic personal cases and a review of the literature data were performed to describe the chest X-ray findings of Legionella pneumophila (LP) community acquired pneumonia. X-ray review was performed simultaneously and in consensus by two radiologists (J.P.T., E.C.) and a physician (C.G.). RESULTS: From our series, 17 patients had an abnormal chest X-ray on admission. Among these pathological X-ray cases, infiltrates were more often confluent (n=16), or patchy (n=7), rather than interstitial (n=1). Fifteen patients had infiltrates involving the lower lung fields. Bilateral distribution of abnormalities and pleural effusion were each observed in three cases. Radiological findings deteriorated between the second and seventh days following admission, particularly in the form of patchy infiltrates with pleural effusion. The review of the literature is consistent with these findings, by reporting prevalent confluent or patchy infiltrates. CONCLUSIONS: These findings are consistent with the physiopathological particularity of this affection and incite us to avoid the classification "atypical pneumonia" in radiologic terminology. This term is more appropriate for clinical and microbiological use.

[Imogam rage prescription assessment in the rabies prophylaxis center of Poitiers]. / Evaluation de la pertinence de la prescription d'Imogam rage au centre antirabique de Poitiers.

OBJECTIVES: Imogam rage (IgR) prescriptions were assessed in the rabies prophylaxis centre of Poitiers (France). MATERIAL AND METHODS: All medical records closed between January 1 and June 1, 2005 were retrospectively analyzed. An infectious disease specialist examined the pertinence of IgR prescription according to WHO references adapted to the epidemiological situation by the Pasteur Institute French rabies center. The indicator used was the proportion of patients treated by IgR among all patients treated by vaccination or vaccination with IgR. RESULTS: During the study period, 69 medical records have bewereen analyzed: 48 (70%) patients were treated including 22 (46%) with IgR. Imogam rage indication was not appropriate for 21 (95%) patients (one contact with a rodent, 8 low gravity contact, 12 contacts with a French animal) that is to say 86 IgR vials. The direct cost was 8,032 euros. CONCLUSION: This assessment permitted to underline an overprescription of IgR, to adapt guidelines to the local situation, and to improve care quality by adaptating medical record files, improving the prescription decisional tree and the local guidelines, and improving the training of interns.

Botulism in patients who inhale cocaine: the first cases in France.

We describe 2 cases of mild botulism in patients who inhaled cocaine. Botulism, though rare, is increasing in incidence among illicit drug users. To our knowledge, these are the first cases of botulism in illicit drug users in France. Clinicians should be aware of this phenomenon; botulism should be considered in illicit drug users with neurological symptoms.

Rapid HIV test in family practice.

BACKGROUND: The 2010-2014 HIV/AIDS French program recommends using HIV rapid diagnostic tests in family practice. Our aim was to assess the acceptability and feasibility of the RDT in family practice in France. METHODS: The first part of this study was to determine the opinions of family practitioners (FPs) concerning the news guidelines for screening and the possible use of rapid HIV tests in their practice. The second part was a feasibility study of the actual use of rapid HIV tests given to FPs during six months. The third part was a qualitative analysis of experience feedback to determine the impediments to using rapid HIV tests. RESULTS: Seventy-seven percent of the 352 FPs interviewed were favorable to rapid HIV tests use. The three main impediments were: misinterpretation of test result, complexity of quality control, and lack of training: 23 of the 112 FPs having volunteered to evaluate the rapid HIV tests followed the required training session. Sixty-nine tests were handed out, and three rapid HIV tests were used; the qualitative study involved 12 FPs. The participants all agreed on the difficult use of rapid HIV tests in daily practice. The main reasons were: too few opportunities or requests for use, complex handling, difficulties in proposing the test, fear of having to announce seropositivity, significantly longer consultation. CONCLUSION: Although FPs are generally favorable to rapid HIV tests use in daily practice, the feasibility and contribution of rapid HIV tests are limited in family practice.

Nosocomial sinusitis with isolation of anaerobic bacteria in ICU patients.

OBJECTIVE: To determine the frequency and the eventual clinical characteristics of nosocomial sinusitis with anaerobic bacteria isolation in patients in the intensive care unit (ICU). DESIGN: Retrospective study. SETTING: A 12-bed medical ICU in a teaching hospital. PATIENTS: 30 adult patients with documented nosocomial maxillary sinusitis. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Using appropriate microbiological techniques, 33 anaerobic bacterial strains were isolated in 18/30 patients (60 %) with nosocomial sinusitis. Anaerobic bacteria were associated with aerobic strains in 13 patients (72 %), whereas in 5 patients (28 %) only anaerobic strains were isolated in sinus puncture cultures. The most frequently isolated species were Prevotella sp. (n = 20, 60 %) and Fusobacterium nucleatum (n = 5, 15 %). The production of beta -lactamase was demonstrated in 13/27 gram-negative anaerobic bacteria. All patients in whom anaerobic bacteria were isolated from transnasal punctures had had a nasogastric tube. Patients in whom anaerobic bacteria were isolated more frequently had neurological disorders upon admission (p < 0.02). Ten patients (30 %) had nosocomial pneumonia, 8 of whom had at least one identical strain in both lung and sinus cultures, including 2 patients with anaerobic bacteria isolation. CONCLUSIONS: Using appropriate microbiological techniques, anaerobic bacteria were frequently isolated in nosocomial sinusitis. If necessary, the empirical choice of antimicrobial therapy in patients with nosocomial sinusitis should take into account these results.

Pneumocystis carinii pneumonia in patients with hematologic malignancies: a descriptive study.

Objectives. A retrospective multicentric study was conducted over a five-year period to evaluate the clinical and laboratory characteristics and outcome of patients with proven Pneumocystis carinii pneumonia (PCP) complicating hematologic malignancies.Results. The study included 60 HIV-negative patients with 18 non-Hodgkin's malignant lymphoma (30%), 13 chronic lymphocytic leukaemia (21.7%), 10 acute leukemia (16.6%), 5 multiple myeloma (8.3%), 4 Waldenström's diseases (6.6%), 4 chronic myeloid leukemia (6.6%), 3 myelodysplasia (5%), 2 Hodgkin's diseases (3.3%) and 1 thrombopenia. Bronchoalveolar lavage was diagnostic in all patients. Forty-nine patients received cytotoxic drugs (81.7%), 25 (41.7%) a long-term corticotherapy and 15 (25%) underwent bone marrow transplantation. Twenty-seven patients (45%) required admission in the intensive care unit, 35 (58.3%) received an adjunctive corticotherapy and 18 mechanical ventilation (30%). Twenty patients (33.3%) died of PCP. A previous long-term corticotherapy (p=0.04), high respiratory (p=0.05) and pulse rates (p=0.02), elevated C reactive protein (p=0.01) and mechanical ventilation (OR=13.37; IC: 1.9-50) were associated with a poor prognosis. Adjunctive corticotherapy did not modify the prognosis.Conclusions. These results suggest that PCP can occur during the course of various hematologic malignancies, not only lymphoproliferative disorders. Prognosis remains poor. The diagnosis should be advocated more frequently and earlier to improve the prognosis.

[Details of meningitis in the elderly]. / Particularités des méningites du sujet âgé.

PURPOSE: Elderly patients being more at risk for infections than younger people, this study was aimed at defining the epidemiological and clinical features of meningitis in this population, with the objective of improving diagnosis and management. METHODS: Over a period of 10 years, all cases admitted to an infectious diseases unit for acute meningitis were reviewed. Patients infected by human immunodeficiency virus (HIV), fungi meningitis, and who were younger than 15 years of age were excluded from the study. According to age, two groups were constituted (group A: < 65 years and group B: > or = 65 years) and compared. RESULTS: One hundred fifty-two patients were included in the study: 110 (72.4%) in group A (29 with bacterial and 81 with viral meningitis) and 42 (26.7%) in group B (32 with bacterial and ten with viral meningitis); the mean age was, respectively, 32.7 +/- 12.9 years (range: 15-61 years) and 75.9 +/- 7.6 years (range: 65-94 years). Diagnosis was less frequently evoked in the elderly (n = 11; 26%) than in younger patients (n = 78; 71%) (P < 0.001). Streptococcus pneumoniae, Listeria monocytogenes, and herpes simplex virus were the three most common causal agents in group B. Confusion was the most common symptom among the elderly (88 vs. 17%; P < 0.001). The mortality rate was more important in group B than in group A (11.9 vs. 2.7%; P = 0.04). CONCLUSIONS: Diagnosis of acute meningitis is difficult and must be evoked in the presence of any new neurologic sign. Cranial computerized tomography should not delay lumbar puncture, except in the presence of focal neurologic symptoms. Antimicrobial therapy takes into account the bacterial epidemiology.

[Association of systemic diseases and myelodysplastic syndromes. A retrospective study of 14 cases]. / Association maladies systémiques et syndromes myélodysplasiques. Etude rétrospective portant sur 14 observations.

CONTEXT: The association of a systemic disease (SD) and a myelodysplastic syndrome (MDS) may not be a coincidence. We report 14 cases. METHODS: A retrospective study was conducted in patients presenting with an MDS, hospitalised between 1989 and 1999, in the search for a concomitant systemic disease. RESULTS: Ninety-seven patients, 61 men and 36 women, with a mean age of 74 +/- 11 years suffered from an MDS and 14 of them a concomitant SD: one nodular periateritis, 2 systemic vascularitis, 2 cutaneous vascularitis, 2 atrophic polychondritis, 4 Gougerot-Sjogrën syndrome, 2 systemic lupus and one cutaneous lupus. The systemic disease did not appear to influence survival. CONCLUSION: It is possible that the association is not a coincidence and therefore an MDS should be searched for when confronted with an SD, so that treatment may be adapted appropriately.

[Imported malaria: prevention should strengthened]. / Paludisme d'importation: il faut renforcer le message de prévention.

INTRODUCTION: The risk of acquiring malaria infection can largely be prevented by the regular use of chemoprophylactic drugs combined with protective measures against mosquito bites. In a retrospective study we had for aim to evaluate the compliance to malaria chemoprophylaxis in patients presenting with malaria infection. METHODS: We analyzed the compliance to the recommended malaria chemoprophylaxis of French travelers hospitalized in a department of infectious diseases because of malaria infection, between January 1999 and December 2003. RESULTS: Eighty-five patients, with a mean age of 34.1 years (16-65) were treated for malaria infection. Seventy-seven were due to Plasmodium falciparum. The outcome was favorable for all patients, despite four severe accesses. Forty-six patients (54%) did not take any chemoprophylaxis (CP), 19 (22%) had an inadequate CP for the risk, 13 (15%) badly complied with intermittent intake of CP and seven (8%) complied well with the recommended malaria CP. Among the 85 patients, 27 (32%) had come to the travelers' consultation and been given recommendations and a recommended malaria CP prescription before traveling. CONCLUSION: These results confirm that the majority of imported malaria cases is a consequence of bad compliance to CP. Understanding user profiles and factors predicting non-compliance may help us to improve pretravel counseling, thereby reducing the risk for travelers to acquire malaria infection.

Update on human rabies in a dog- and fox-rabies-free country.

UNLABELLED: Rabies is responsible for 50,000 deaths per year worldwide. Mainland France has been officially freed from rabies in non-flying animals since 2001. METHOD: We wanted to provide an update on the French situation, using published data, and describe possible options since official guidelines are lacking. RESULTS: Post-exposure prophylaxis (PEP) (early and careful cleaning and dressing of the wound, vaccination, and in case of high-risk exposure, injection of specific anti-rabies immunoglobulins) is known to be efficient except in rare cases. It is recommended after grade II contact (+specific immunoglobulins in immunodepressed patients), or grade III contact (vaccination+immunoglobulins). DISCUSSION: Mainland France being rabies-free, 3 options may be considered in case of bite by a dog or a cat that cannot be monitored in France: (a) consider the risk of rabies as null, so no PEP should be administrated, whatever the severity of bites; (b) consider there is a weak but lethal risk, so the international recommendations should be applied, using immunoglobulins in some cases; (c) consider that the risk is extremely low but cannot be excluded, and that the patient should be vaccinated to be protected, but without adding immunoglobulins (whether in case of grade II or III bites). CONCLUSION: There are no national guidelines for rabies in France, and so the physician managing the patient is the one who will decide to treat or not.

Effectiveness and safety of saquinavir/ritonavir in HIV-infected pregnant women: INEMA cohort.

OBJECTIVE: The authors had for aim to describe the effectiveness and the safety of a saquinavir/ritonavir (SQV/r) regimen, 1000/100mg twice daily, in HIV-infected pregnant patients. PATIENTS AND METHOD: We made a prospective and observational study of HIV positive female patients beginning or going on SQV/r antiretroviral treatment (ART) during pregnancy. RESULTS: Sixty-two patients were enrolled from July 2007 to June 2009 in 10 infectious diseases units in France. Thirty-six women (group 1) were ART naive on inclusion, 20 (group 2) had been previously treated and then switched to SQV/r, six (group 3) were treated with SQV/r before pregnancy. 58 patients delivered while on SQV/r regimen after a median pregnancy duration of 39 WA. Eighty percent had a viral load below 50 copies/mL and 93% below 400 copies/mL: respectively 77% and 93.5% in group 1, 83% and 89% in group 2, 83% and 100% in group 3. The median SQV minimum concentrations (C(min)) measured at the third trimester and at delivery were adequate, respectively 0.91 mg/L and 0.86 mg/L. Most women (52%) had a vaginal delivery; 12 (21%) had an elective caesarean section, for obstetrics factors in eight cases. None of the newborns were HIV-infected at 6 months of age (n = 59, one death at day 3). Only one severe adverse event occurred due to saquinavir (maternal grade 3 hepatotoxicity). CONCLUSION: SQV/r 1000/100mg twice daily seems to be effective and safe in HIV-infected pregnant women with adequate saquinavir C(min).
