Antibiotic prescription by general practitioners for urinary tract infections in outpatients.

In July 2008, in France, guidelines for antibiotic prescriptions for urinary tract infections (UTIs) were amended. As general practitioners (GPs) treat numerous UTIs, we wanted to evaluate whether they followed these guidelines. In order to do this, we performed a prospective study. The point of call was urinalyses. Using this selection method together with criteria diagnostic for urinalysis, we confirmed that patients presented a UTI. Each GP was contacted. Prescriptions were analysed and compared to the 2008 French guidelines for UTIs. Our study included 185 urinalyses. UTIs diagnosed by GPs were as follows: acute cystitis: 72.4 %, prostatitis: 13.5 %, nephritis: 8.7 % and asymptomatic bacteriuria: 5.4 %. The principal antibiotics used were: quinolone (59.5 %), furan (17.8 %) and cotrimoxazole (6.5 %). Only 20 % of the prescriptions were compliant with the guidelines. The correct antibiotic but not the dose or the duration of prescription was selected in 8.1 % of the prescriptions. For cystitis, inappropriate prescription was associated with an extra cost of 694 , namely, 7.4 per treatment. GP prescriptions for UTIs do not follow the guidelines. Even if GPs assert that they are aware of the emergence of resistant strains, it seems that they do not take into account the objective of quinolone restriction, which was one of the backbones of these guidelines.

[Sleeping Sickness: A Cause of False Positive HIV Rapid Diagnostic Tests]. / Maladie du Sommeil: Une Cause de Faux Positifs des Tests de Diagnostic Rapide du VIH.

Approaching the mechanisms related to false positives HIV rapid diagnostic tests (RDT) in patients with sleeping sickness may help to improve the accuracy of screening for HIV infection in areas endemic for Human African trypanosomiasis (HAT).We report on a patient from Congo who was managed like an AIDS-associated meningoencephalitis, based on a false positive HIV RDT at admission, and eventually received a diagnosis of sleeping sickness. A further retrospective cohort study performed in patients with HAT shows that most of positive HIV RDT obtained prior to treatment for sleeping sickness are false positives. We found that half of them were cleared at the end of treatment course, suggesting an early clearance of some antibodies involved in cross-reactivity.A substantial clearance of HIV RDT false positives occurs during therapy for HAT. In areas where Elisa HIV tests are not readily available, repeating the HIV RDT at the end of therapy may help to identify roughly half of false positives.

[Post-menopausal endometrial tuberculosis]. / Tuberculose utérine post-ménopausique.

A 69-year-old menopaused woman, presented a 2-month history of metrorrhagia. We suspected a malignant disease, but, the histopathologic examination of biopsies, found an endometrial inflammation without malignant cells. Culture for mycobacteria showed a Mycobacterium tuberculosis. A course of four-drug antituberculous therapy was started and the patient recovered. Tuberculosis remains a common disease, but genital infection is infrequent. Usually, it concerns young infertile women from non-industrial countries. More attention should be paid to this disease. Women, irrespective of their age, should be investigated for silent or subclinical genital symptoms, with mycobacterial examination.

[Reactive arthritis due to Clostridium difficile]. / Arthrite réactionnelle a Clostridium difficile.

Extracolonic manifestations of Clostridium difficile infections have rarely been reported as a cause of reactive arthritis. We report the case of a monoarticular arthritis following pseudomembranous colitis. A 45 year-old man was admitted for fever and monoarthritis of the left knee, 8 days after the onset of a C. difficile enterocolitis associated with urethritis. Samples obtained from the knee, urine, and blood cultures remained sterile. Bone scintigraphy revealed a left knee and forefoot hyperfixations. The association of arthritis and urethritis led us to the diagnosis of Fiessinger-Leroy-Reiter syndrome. Antibiotics for arthritis were ineffective and stopped, but they were continued for colitis. NSAIDs were prescribed and clinical manifestations disappeared within 24 hours, the patient resumed walking after 48 hours. Four months later there was no relapse and no sequela.

Spectrum of advice and curbside consultations of infectious diseases specialists.

OBJECTIVES: Curbside consultation (CC) of infectious diseases specialists for advice is very frequent but the corresponding workload has rarely been assessed. This activity is mostly oral (phone or direct contact) and poorly quantifiable because it is not charged. We had for aim to evaluate this activity in a French teaching hospital. METHODS: We recorded all CCs given during a 2.5-year period, from mid-2011 to the end of 2013. RESULTS: During the study period, 6789 CCs were recorded (2715 per year), or slightly more than 10 per day. These CCs were divided in 676 travel recommendations and 6113 for other reasons. They were mostly given by phone (77.4%). Most demands came from our hospital (61.4%), followed by community family physicians and specialist (27.1%), other local hospitals (6.5%) and clinics (4.3%). All the departments in our hospital consulted us for advice at least once and answers were mainly given by phone (70.1%) and at bedside (30.5%). The answers were principally advice (50.8%), modification of antibiotic prescription (22.9%), initiation of antibiotic course (14.8%), maintaining the same treatment (6.2%), and stopping antibiotics (4.3%). CCs accounted for 20% of clinical work for 1 physician. If the CCs in our hospital had been paid, our department would have received an additional 77,000€ in revenue. CONCLUSION: This curbside activity is very important and time-consuming for infectious diseases specialists, but it is currently not acknowledged or rewarded.

[Community-acquired meningitis due to methicillin susceptible Staphylococcus aureus]. / Méningites communautaires à Staphylococcus aureus méticilline sensible.

UNLABELLED: Meningitis due to Staphylococcus aureus is infrequent. MRSA is mainly found after neurosurgery, but MSSA may be involved in community-acquired meningitis. However, this kind of infection is not widely reported, despite its severity. METHODS: We describe the characteristics of five patients hospitalized in our ward over a period of 18 months who presented with community-acquired meningitis due to MSSA. RESULTS: The patients were three men and two women with a mean age of 62 years. One patient was immunosuppressed. Neurological signs were present at the onset for only two patients. In all cases, there were extraneurological localizations of the infection, mainly in bones (spondylodiscitis, epidural abscess, arthritis) but also lung infection. Three patients with meningeal inflammation also presented with confusion. CSF analysis revealed less than 950 white blood cells, hyper-CSF-proteins, and hypo-CSF-glucose. Bacteraemia was present in all patients. The source of infection was never determined. The evolution was good for all patients with a prolonged antibiotic course. The analysis of genetic determinants for three strains revealed the presence of TSST-1 which could account for the severity of the disease. CONCLUSION: Community-acquired MSSA meningitis is a serious infection, occurring in patients without risk factors. Hematogenous dissemination leads to multiple tissue infection. A long course of antibiotics, with high doses, is needed to treat meningitis but also extraneurological localizations. The role of TSST-1 needs to be confirmed in other patients.
