Six days after doxycycline administration, PCR with the buffy coat sample was negative but PCR with a crust tissue sample from the tick-bite site remained positive. This is the first case to suggest that crust tissue at the tick-bite site may be useful for early HGA diagnosis in patients who have already been treated with antibiotics such as ...

AbstractUniversal access to safe drinking water is a global priority. To estimate the annual disease burden of campylobacteriosis, nontyphoidal salmonellosis, cryptosporidiosis, giardiasis, and norovirus attributable to waterborne transmission in Australia, we multiplied regional World Health Organization (WHO) estimates of the proportion of cases attributable to waterborne transmission by estimates of all-source disease burden for each study pathogen. Norovirus was attributed as causing the most waterborne disease cases (479,632; 95% uncertainty interval [UI]: 0-1,111,874) followed by giardiasis and campylobacteriosis. The estimated waterborne disability-adjusted life year (DALY) burden for campylobacteriosis (2,004; 95% UI: 0-5,831) was 7-fold greater than other study pathogens and exceeded the WHO guidelines for drinking water quality (1 × 10(-6) DALY per person per year) by 90-fold. However, these estimates include disease transmitted via either drinking or recreational water exposure. More precise country-specific and drinking water-specific attribution estimates would better define the health burden from drinking water and inform changes to treatment requirements.

BACKGROUND: Due to increasing antimicrobial resistance, a bismuth-based quadruple regimen has been recommended as an alternative first-line therapy for Helicobacter pylori (H pylori) eradication. However, different results are varied greatly and the availability of bismuth was limited in some countries. We assessed the efficacy and safety of 14-day berberine-containing quadruple therapy as an alternative regimen for H pylori eradication. METHODS: In a randomized, open-label, non-inferiority, phase IV trial between November 25, 2014, and October 15, 2015, 612 treatment-naive patients were randomly assigned to 14-day berberine-containing (n = 308) or 14-day bismuth-containing (n = 304) quadruple therapy. The primary outcomes were eradication rates determined by the C urea breath test (C-UBT) 28 days after the end of treatment. The secondary outcomes were adverse events and compliance. RESULTS: The baseline demographic data including age, gender, body mass index (BMI), general condition and severity score were not statistically different in both groups. The eradication rates in bismuth and berberine groups were 86.4% (266/308) and 90.1% (274/304) in intention-to-treat (ITT) analysis (P = .149), and 89.6% (266/297) and 91.3% (273/299) in per-protocol (PP) analysis (P = .470), respectively. No statistically significant difference was found in the overall incidence of adverse events between both groups (35.7% vs 28.6%, P = .060). CONCLUSIONS: Both regimens achieved the recommended efficacy for H pylori eradication. The berberine-containing quadruple regimen was not inferior to bismuth-containing quadruple regimen and can be recommended as an alternative regimen for H pylori eradication in the local region.

10. A case of Q fever with erythema nodosum.  
Date: 08/18/2017
BACKGROUND: Acute Q fever is asymptomatic in 60% of the patients, while the reminder may present with fever, pneumoniae, and hepatitis. Skin manifestations are uncommon including transient punctiform rashes, purpuric, or maculopapular eruptions. Erythema nodosum have seldom been reported. CASE PRESENTATION: A 37-year-old female presented with fever for 1 month and skin lesions consists of erythematous painful nodule of the legs. Serological testing for Coxiella burnetii was positive. Treatment consisted with doxycycline for 2 weeks. Evolution was favorable. The patient completely recovered and had no evidence of skin lesion 1 month later. CONCLUSION: Because of its nonspecific clinical presentation, Q fever with erythema nodosum is probably underestimated. Q fever should be evocated when facing unexplained erythema nodosum even if there is not other typical clinical manifestation of Q fever.

Tularemia in humans in northwestern Spain is associated with increases in vole populations. Prevalence of infection with Francisella tularensis in common voles increased to 33% during a vole population fluctuation. This finding confirms that voles are spillover agents for zoonotic outbreaks. Ecologic interactions associated with tularemia prevention should be considered.

Nowadays, one of the major problems of brucellosis is its high recurrence rate and using more than one course of standard treatment regimens. Therefore, more researches need to find more effective treatments which lead to prompt recovery and reduce the relapse of disease. This single-blind randomized study was designed to evaluate the effect of the standard treatment of brucellosis in combination with hydroxychloroquine. Totally, 177 patients with acute brucellosis were randomly assigned to one of two treatment groups including doxycycline-streptomycin (DS) and doxycycline-streptomycin-hydroxychloroquine (DSH). Clinical symptoms and signs, serological tests, and side effects of therapy were compared between two groups during treatment course and also at three and six months after the end of drug therapy. Of the 177 patients with the mean age of 40.5±16.9 years, 66.1% were males and the others were females. The mean duration of clinical signs prior to admission was 43.4±41.1 days. Appropriate clinical responses, relapse, treatment failure, and adverse drug reactions were seen in 98.9%, 1.2%, 0.0%, and 12.6% of patients in DSH group vs. 86.7%, 11.6%, 2.3%, and 19.8% of patients in DS group, respectively. There were significant differences in clinical response and relapse rates between the two groups. It seems that addition of hydroxychloroquine to doxycycline-streptomycin regimen lead to the increased efficacy of treatment; accelerated improvement of clinical symptoms and significantly reduced relapse rate of brucellosis.

OBJECTIVE: Melioidosis may be endemic in many tropical developing countries but diagnosis of the disease is currently unreliable in resource-limited areas. Here we aimed to validate a simple and cheap laboratory algorithm for the identification of Burkholderia pseudomallei from clinical specimens in parts of Vietnam where the disease has not been reported before. METHODS: In June 2015, we conducted training courses at five general hospitals in north central provinces in order to raise awareness of the disease and to introduce a simple and cheap laboratory identification algorithm for B. pseudomallei including the Three Antibiotic Disk Test. RESULTS: Until the end of the year (7 months later), 94 suspected B. pseudomallei strains resistant to gentamicin and colistin but sensitive to amoxicillin/clavulanic acid were detected from clinical specimens of 70 patients. All strains were further confirmed as B. pseudomallei by using a specific TTSS1 real-time PCR assay and recA sequencing analysis. Among positive blood cultures, positive rates with B. pseudomallei ranged from 3.4% (5/147) to 10.2% (32/312) in the various clinics. 82.8% (58/70) of patients were bacteraemic, with a mortality of 50% (18/36) among patients with known outcome. No death occurred in non-bacteraemic patients. CONCLUSION: Our results demonstrate that the introduction of a simple and easy-to-perform laboratory algorithm for the identification of B. pseudomallei from clinical samples together with clinical awareness raising can lead to the diagnosis of a significant number of melioidosis cases in resource-limited clinical laboratories which previously did not identify the pathogen.

Further brain imaging by MRI reveled no abnormalities. Lyme serology (antibodies against purified VlsE-1 and PepC10 antigens) was negative (index value 0.6;≤0.90 negative. Complete blood count and metabolic panel were within normal limits. Only objective physical finding was a right erythematous ear canal so the patient was prescribed a 7-day course of amoxicillin/clavulonic acid.

... endoscopic investigation AbstractText: B. pseudomallei was isolated from 9/83 (11%) stools and 9/58 (16%) rectal swabs from 141 patients with melioidosis. All stools from 244 control patients and 799 gastric biopsies from 395 patients with no evidence of melioidosis were culture negative for B. pseudomallei. It is not uncommon for melioidosis patients to shed B. pseudomallei in stool.

AIMS: To determine the frequency and clinical presentation of Lyme disease in patients with uveitis and to assess the value of Borrelia burgdorferi serological testing. METHODS: Retrospective study on all patients with uveitis who were referred to our tertiary hospital were serologically tested for Lyme in our laboratory between 2003 and 2016. Screening consisted of determining B. burgdorferi serum IgG and IgM by ELISA method. The patient's serology was considered as positive if the ELISA-positive result in IgM and/or IgG was confirmed by an immunoblot positive in IgM and/or IgG. Lyme-associated uveitis was diagnosed based on serological results as well as response to antibiotics and exclusion of other diagnosis. RESULTS: Of the 430 patients with uveitis (60% women, mean age 49 years) fulfilling inclusion criteria, 63 (14.7%) had an ELISA-positive serology, confirmed by immunoblot for 34 patients (7.9%). The diagnosis of Lyme-associated uveitis was finally retained in seven patients (1.6%). These patients reported either a previous exposure including tick bite or forest walks (n=5), symptoms suggestive of Lyme disease (n=5) and resistance to local and/or systemic steroids (n=7). Among the remaining 27 positive patients, 22 had other established aetiologies and 5 other were unclassified. CONCLUSION: The seroprevalence of B. burgdorferi among our patients with uveitis was 7.9% compared with 6 to 8.5% in the general French population which leads to a low predictive value of serological testing. Its use should be reserved for patients with unexplained uveitis, an exposure history, systemic findings suggestive of Lyme disease and steroids resistance.
