An outbreak of Pneumococcal pneumonia among residents of a retirement home in France during October 2003.

We describe an outbreak of pneumonia due to Streptococcus pneumoniae in a French retirement home. Eleven residents developed pneumonia. Eight patients had positive results of urinary antigen tests. There were no further cases after the implementation of control measures, which involved isolation of and receipt of antibiotic therapy by symptomatic residents. No risk factors for transmission of S. pneumoniae were identified in this population.

Impact of the use of aminoglycosides in combination antibiotic therapy on septic shock and mortality due to Staphylococcus aureus bacteremia.

BACKGROUND: The purpose of this study was to evaluate the possible impact of antimicrobial combination regimens containing an aminoglycoside (AG) on morbidity and mortality associated with S. aureus bacteremia. METHODS: All inpatients over 18 years of age with S. aureus bacteremia were prospectively enrolled in three tertiary care hospitals in France and Ireland. Patients were included in the group "treated with AG" if they received at least 24 h of aminoglycoside therapy within 7 days after a positive blood culture in combination with an effective antimicrobial against the S. aureus. A Cox's proportional hazard model was used in univariate and multivariate survival analysis, the covariate "treatment with AG" being introduced as a time-dependent covariate. RESULTS: Nine percent of the 90 patients who received AG died because of infection versus 13% in the group that did not receive a combination including an AG (p>0.05). In the multivariate Cox model, stratified by septic shock and controlling for age and Charlson-weighted index of comorbidity, the adjusted odds ratio for death due to S. aureus infection associated with the use of AG was 0.6 [95% CI: (0.2-1.9); p=0.4]. However, AG was found to have a protective effect on septic shock occurrence [OR=0.3; 95% CI: (0.1-0.7), p=0.004], controlling for age, portal of entry not related to catheter infection, and diabetes. CONCLUSION: Although there was no decrease in mortality due to S. aureus infection in patients treated with AG therapy, we found a significant benefit of AG in preventing septic shock. This data argues for the early use of AG in patients with S. aureus bacteremia.

Comparison of microbiological results of needle puncture vs. superficial swab in infected diabetic foot ulcer with osteomyelitis.

AIM: To study prospectively two methods for the bacteriological diagnosis of osteomyelitis related to diabetic foot ulcer: needle puncture performed across normal skin surrounding the foot ulcer and superficial swabbing of the ulcer. PATIENTS AND METHODS: Diabetic patients with a foot ulcer complicated by bone or joint infection, as detected by X-ray imaging, were included in the study. Ulcer swabbing and needle puncture were performed in each patient. To reach the tissue nearest the bone surface, needle puncture was guided by X-ray imaging and the drop of fluid obtained by aspiration was used for both aerobic and anaerobic bacterial culture. RESULTS: Twenty-one diabetic patients were included. The mean number of microorganisms isolated by needle puncture was significantly lower compared with that obtained by superficial swabbing: 1.09 vs. 2.04 (P < 0.02). Three bacterial species were isolated by needle puncture only in one patient while three or more bacterial isolates were obtained by superficial swabbing in six patients. No bacterial isolate was detected in five patients by needle puncture and in two patients by superficial swabbing. Staphylococcus aureus accounted for 70% of cases (seven patients) when a single bacterial species was obtained by needle puncture. After needle puncture, no wound complication or infection was observed. CONCLUSION: Culture of samples obtained by needle puncture revealed one or two bacterial isolates in two-thirds of diabetic patients with osteomyelitis following foot ulcer. Given the lack of complications, this invasive diagnostic technique should be considered for deep direct sampling in diabetic patients with osteomyelitis related to foot ulcer when surgical debridement is contraindicated or delayed.

[Cogan's syndrome revealed by haemorrhagic glairous diarrhoea].

INTRODUCTION: Cogan's syndrome is defined by the combination of non syphilitic interstitial keratitis and inner ear dysfunction, similar to Meniere's disease. OBSERVATION: Cogan's syndrome was revealed by haemorrhagic glaireous diarrhoea in a 21 year-old woman whose medical history included Hirschsprung's disease. Cerebral MRI revealed viral-like bilateral neuritis of the eighth cranial nerve, never described in the literature before. The auditory and visual disorders regressed after treatment with corticosteroids. CONCLUSION: The early diagnosis of Cogan's syndrome permits the cure of the visual and auditory and notably inner ear symptoms with corticosteroid therapy.

A case of Aspergillus mediastinitis after heart transplantation successfully treated with liposomal amphotericin B, caspofungin and voriconazole.

Reported here is a case of mediastinitis caused by Aspergillus fumigatus and Staphylococcus epidermidis following a heart transplantation that was successfully treated with amphotericin B in combination with new antifungal drugs (caspofungin and voriconazole), antibiotics and superficial wound drainage. A review of the literature revealed that Aspergillus as a cause of mediastinitis has been rarely described. In the few existing reports, evolution was generally fatal, especially in immunocompromised patients, despite treatment with antifungal drugs and surgery.

[Management of erysipelas in French hospitals: a post-consensus conference study].

INTRODUCTION: A prospective hospital-based survey on the management of bacterial dermal-hypodermal infections was conducted before the consensus conference "How should Erysipelas-Necrotic Fasciitis be managed?". The results of the survey were circulated early in 2001. To assess the eventual impact of the guidelines from the conference on hospital practices with regard to erysipelas, we conducted a new prospective survey at the end of 2002. PATIENTS AND METHODS: The questionnaire used was identical to that of the 2001 survey. It collected, anonymously, data on the clinical characteristics, supplementary examinations conducted (bacteriology, imaging), initial treatment and outcome. The questionnaire was mailed to the departments of dermatology, internal and/or infectious diseases and intensive care that had replied to the first survey (n = 124). The patients eligible for inclusion were those hospitalized between 09/01/2002 and 11/30/2002. Statistical analysis compared the results with those of the preceding survey. RESULTS: The files of 245 patients were collected that came from 41 departments (15 from university hospitals, 23 from general hospitals and 3 from military hospitals) and 235 of whom had erysipelas. For those with erysipelas, the mean age was of 65 +/- 2.5 years, the M/F sex ratio was of 0.66 and the localization was the leg in 89.5 p. 100 of cases. A Doppler of the legs was performed in 33 p. 100 of cases. The initial antibiotherapy was penicillin G in 38 p. 100 of cases and pristinamycine in 18 p. 100 (others: 44 p. 100). The route of administration was initially intravenous in 73 p. 100 of cases. An anti-coagulant was associated in 60 p. 100. The outcome was favorable in 94 p. 100 of cases, with a mean duration of hospitalization of 11.2 +/- 1.2 days and antibiotics of 17.7 +/- 1.3 days. Dopplers and the blood cultures were performed more frequently than before the consensus conference, but no difference was found in the antibiotics or adjuvant therapies. DISCUSSION: The follow-up survey showed the stability of hospital practices concerning erysipelas, notably with regard to treatment. In contrast, the clear tendency in limiting the supplementary examinations is in agreement with the consensus conference.

Suspected SARS patients hospitalised in French isolation units during the early SARS epidemic: the French experience.

During the SARS epidemic, many patients were screened according to WHO criteria but never went on to develop SARS. In May 2003, early in the epidemic, we conducted a retrospective study to describe suspected SARS patients hospitalised in France and compared them with documented cases of patients with SARS to evaluate the screening strategy. A total of 117 patients were studied. Only 3.4% had been in close contact with a SARS patient but 73.5% came from an affected area. 67.5% had fever and respiratory symptoms on their admission to hospital. 49.6% had fever and non specific symptoms. Clinical symptoms that were significantly more common among patients with SARS were fever, myalgia, dyspnoea, and nausea or vomiting. Presumed viral fever and respiratory tract infection were the most common diagnosis. Symptoms cannot be distinguished from an early stage of SARS confirming the usefulness of the WHO case definitions in isolation decision to avoid further transmission.

Positive surveillance blood culture is a predictive factor for secondary metastatic infection in patients with Staphylococcus aureus bacteraemia.

PURPOSE: Staphylococcus aureus bacteraemia (SAB) may be complicated by secondary metastatic infection such as endocarditis, osteomyelitis or septic arthritis. This cohort study aimed to assess the prognostic value of sustained bacteraemia for outcomes related to Staphylococcus aureus bacteraemia. SUBJECTS AND METHODS: The study took place in three tertiary-care, university-affiliated hospitals. Patients were prospectively included if they agreed to participate and if the following data were available: (a). surveillance blood culture taken between 24 and 48 h after commencement of effective antibiotic therapy; (b). appropriate investigations (at least a TTE) performed as suggested by the infectious diseases consult service. Patients with sustained bacteraemia defined as persistent positive blood cultures more than 24 h after commencement of effective antibiotic therapy were compared to patients for whom the surveillance blood culture was negative. RESULTS: One hundred and four patients were enrolled, including 51 patients diagnosed with sustained bacteraemia. Sustained bacteraemia was significantly associated with a higher frequency of secondary metastatic infection (p<0.001) and with a higher frequency of CRP>100 mg/l. Frequency of acute complications due to infection, septic shock and death due to bacteraemia was higher for patients with sustained bacteraemia but this difference was not statistically significant. Using a Cox model, the risk for death associated with sustained SAB, controlling for Index of comorbidity and age (categorised as or=70 years), was 1.2 (95% CI: (0.5, 3); p>0.05). CONCLUSION: In conclusion, surveillance blood cultures, especially performed on effective antibiotic therapy, may be a simple and cost-effective way to select a population at risk for secondary metastatic infection from SAB.

[Risk factors for nosocomial Clostridium difficile diarrhoea in an infectious and tropical diseases department].

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.

[Pharmacokinetics and dose adaptation of ofloxacine, pefloxacine and ciprofloxacine during haemodialysis and continuous ambulatory peritoneal dialysis].

Fluoroquinolones present various pharmacokinetic properties. That's the way we carried out a bibliographic summary about the pharmacokinetics of pefloxacin, ofloxacin and ciprofloxacin in patients hit by chronic renal failure, under haemodialysis or under continuous ambulatory peritoneal dialysis. Then, we will describe how to adapt drug dose according to the degree of renal insufficiency and the used molécule.

[Severe acute respiratory syndrome (SARS). The questions raised by the management of a patient in Besançon and Strasbourg].

INTRODUCTION: In mid-June 2003, 8500 probable cases of Severe Acute respiratory Syndrome (SARS) responsible for 800 deaths in 29 countries were reported by the World Health Organization (WHO). In France, 5 probable cases of SARS were diagnosed until May 2003. We report the case of one of the 5 French cases, hospitalized successively in Besançon then in Strasbourg. OBSERVATION: This 54 year-old man was infected during the Air France flight from Hanoi to Paris via Bangkok by the index case, who himself had been contaminated at the French hospital in Hanoi and who was hospitalized in a critical state in the Tourcoing hospital shortly after his arrival in France. The first clinical signs (fever and dry cough) appeared 4 days after contact with the index case. The chest X-ray showed a pulmonary consolidation 6 days after the first clinical symptoms. Blood test revealed deep lymphopenia and elevated LDH. The patient finally recovered with a treatment combining ribavirin and steroids. CONCLUSION: The clinical symptoms of SARS are unspecific and its evolution may be misleading. The epidemiological context (contact with the index case) is a key point for the diagnosis. The management of such a patient requires the careful protection of contacts, the adequation between medical and paramedical staff and excess work and communication to the general public.

Human anaplasmosis presenting as atypical pneumonitis in France.

Human anaplasmosis is a febrile illness caused by Anaplasma phagocytophilum, an intracellular bacterium transmitted by Ixodes ticks in the United States and Europe. Although cough is reported in 30% of the American cases, interstitial pneumonitis has been noted only once. Of the 9 confirmed cases reported in Europe, 3 presented with atypical pneumonitis. A. phagocytophilum should be added to the list of agents responsible for interstitial pneumonitis, especially in areas where human anaplasmosis is endemic.

[Dumbbell nephroblastoma: an uncommon cause of spinal cord compression].

UNLABELLED: Rarely children with Wilms' tumor develop spinal cord dysfunction by metastatic spread into the epidural space or the cord parenchyma. In the case reported here, the mechanism of spinal compression was different. CASE REPORT: The authors report the clinical course of a 2-month-old boy with retroperitoneal extrarenal Wilms' tumor below the left kidney, characterized with a spinal cord compression developed through the intervertebral foramina. CONCLUSION: Abdominal tumor, usually corresponding to neuroblastoma, may be a nephroblastoma.
