RESUMO

We report a case of a pregnant woman with COVID-19 who developed coagulopathy in the absence of severe clinical symptoms. A polymerase chain reaction test of a vaginal swab was positive for SARS-CoV-2 RNA, suggesting a possibility of perinatal transmission. Cesarean delivery was performed because of a non-reassuring fetal heart rate; the placenta showed increased perivillous fibrin deposition and intervillositis. Moreover, placental infection with SARS-CoV-2 was demonstrated by placental immunostaining. The findings suggest a possible relationship between placental fibrin deposition and chronic and acute intervillositis, non-reassuring fetal heart rate and coagulopathy in pregnant women with COVID-19. © 2020 The Authors.

RESUMO

Actinobaculum schaalii is a Gram-positive coccoid rod that causes various infections in humans and is easily overlooked in cultures. A. schaalii has long been thought to be of low prevalence and limited invasive potential, causing benign cystitis in elderly patients with underlying urological conditions. Here, we report the first case of epididymitis caused by this bacterium.

RESUMO

PURPOSE: To exclude urinary tract infections, culture is the gold standard method, although it is time consuming and costly. Current strategies using dipstick analysis are unsatisfactory as screening methods, because of inadequate sensitivity/specificity. Urine flow cytometry is an attractive alternative. To exclude urinary tract infections, a cutoff value to screen for negative cultures was determined. METHODS: 281 outpatients (51 % male) of a general population visiting the urology department were included. Urine samples were measured by flow cytometry and compared with culture results and dipstick analysis. ROC analysis was performed to evaluate the screening performance of flow cytometry and dipstick analysis compared to culture. RESULTS: 18 % of cultures were positive, defined as >10(4) colony forming units/mL. Bacterial count by flow cytometry alone provides the best sensitivity and specificity to exclude a urinary tract infection. A cutoff value of 60 bacteria/µL urine leads to a sensitivity of 100 % and a specificity of 60 %. Retrospectively, with a cutoff value of 60 bacteria/µL urine, 49 % of the cultures would have been redundant. 20 % of patients receiving antibiotics possibly had received those unnecessarily. The calculated percentage of false negatives was 0 % (95 % confidence interval 0-3.3 %). CONCLUSIONS: Urine flow cytometry is a reliable screening method to exclude urinary tract infections. With a cutoff value of 60 bacteria/µL urine, negative predictive value is 100 % and the calculated percentage of false negatives is 0 % (95 % confidence interval 0-3.3 %). Using flow cytometry as a screening method could lead to a reduction in cultures and antibiotics.

RESUMO

The rise in antimicrobial resistance has become a serious global health problem. Restrictive use of antibiotics seems the only option to temper this accession since research in new antibiotics has halted. Antimicrobial stewardship programmes rely on quick access to susceptibility data. This study evaluated the concept of bacterial cell count monitoring as a fast method to determine susceptibility. Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus strains were tested for amoxicillin/piperacillin and gentamicin by three conventional methods (VITEK2(®) , Etest(®) and broth-macrodilution). Bacterial cell count monitoring reliably predicted susceptibility after 90 min for Escherichia coli and after 120 min for Pseudomonas aeruginosa and Staphylococcus aureus without any minor, major or very major discrepancies. Time-to-result was reduced by 74%, 83% and 76%, respectively. Bacterial cell count monitoring shows great potential for rapid susceptibility testing.

RESUMO

INTRODUCTION: A large outbreak of acute Q fever has been reported in the Netherlands with over 3500 cases from 2007 to 2009, during which 749 patients were hospitalised. In foreign cohorts, reported mortality rates in patients hospitalised with acute Q fever, ranged from 0.9 to 2.4%. We analysed mortality among hospitalised patients with acute Q fever in the Netherlands. METHODS: Physicians from hospitals in the afflicted region were asked to provide details about patients who died with a diagnosis of acute Q fever between 2007 and 2009. RESULTS: Nine patients (seven males, median age 72 years) from six hospitals were reported, who died within approximately one month following hospitalisation for acute Q fever. Six definite acute Q fever cases and three probable cases were identified. Six patients presented with infiltrates on the chest X-ray and a median CURB-65 score of 3. Median time of hospitalisation was 13 days (range 1-33). All patients had serious, often coinciding, underlying conditions including chronic cardiovascular disease, chronic lung disease, diabetes mellitus and malignancy. CONCLUSION: The mortality rate of patients hospitalised because of acute Q fever was estimated at approximately 1%. Patients who died with acute Q fever were often male, of older age, and had chronic coinciding underlying conditions, which gives an a priori higher risk of death.

RESUMO

Campylobacter species are frequently isolated from fecal specimens of patients with diarrheal illness. Several Campylobacter species are commonly isolated from the oral cavity. In contrast, Campylobacter species are rarely isolated from extra-oro-intestinal abscesses. Reported here are four cases of extra-oro-intestinal abscesses due to polymicrobial flora, including Campylobacter species. The first case is a 35-year-old woman who was diagnosed with a brain abscess caused by C. gracilis, Streptococcus constellatus, and anaerobic Gram-positive cocci. The second case is a 65-year-old man with a history of maxillary sinus carcinoma who developed a brain abscess due to polymicrobial flora, including C. concisus. The third case is a 24-year-old male who was diagnosed with a vertebral abscess caused by C. rectus, Eubacterium brachy, and Actinomyces species. The fourth case is a 74-year-old woman who presented with an intraorbital abscess due to C. showae and Micromonas (previously Peptostreptococcus) micros. The first two patients died from a cause directly related to their abscesses. All Campylobacter species involved in the four cases were isolated anaerobically. The isolation of oral Campylobacter species, e.g., C. rectus and C. showae, from abscesses suggests an oral source. A survey of the English literature was undertaken to identify reports of Campylobacter species isolated from extra-oro-intestinal abscesses.

RESUMO

BACKGROUND: Dyspepsia is common in western society. Prompt endoscopy is imperative in all patients with sinister symptoms or if symptoms first appear after the age of 50-55 years, but the optimal management of younger patients with uncomplicated dyspepsia is still open to debate. METHODS: The literature on the management of uncomplicated dyspepsia is reviewed and a personal view is presented. RESULTS: Strategies based on non-invasive detection of Helicobacter pylori are probably the most cost-effective. Currently (H. pylori prevalence 30%-40%), a 'test and treat' approach using a non-invasive test to detect H. pylori is likely to be the most efficient first step. If the patient is H. pylori-negative or if symptoms persist after successful H. pylori eradication, empirical treatment with an anti-secretory drug is justified. Endoscopy is reserved for those patients in whom this approach fails. If the prevalence of H. pylori decreases, the positive predictive value of any non-invasive H. pylori test will become too low. A 'test and scope' approach in which a positive test can be confirmed by two or more biopsy-based tests is then more appropriate. At a very low prevalence of H. pylori in the dyspeptic population, non-invasive testing for H. pylori loses its significance and empirical treatment with an antisecretory drug becomes a rational first step. CONCLUSIONS: The optimal approach to management of uncomplicated dyspepsia is dependent on the prevalence of H. pylori among the dyspeptic population. At the current prevalence rate, 'test and treat', followed by acid suppressive treatment in the case of persisting symptoms, is the most appropriate strategy.

RESUMO

In this paper the rationale and limitations of the four most important approach strategies to dyspepsia in primary care (empiric treatment, prompt endoscopy, "test-and-scope", and "test-and-treat") are analysed. It is concluded that in the absence of alarm symptoms, a "test-and-treat" approach is currently the most rational approach provided that three conditions are met: (1) a highly accurate test should be used, (2) the prevalence of Helicobacter pylori in the population should not be too low, and (3) an effective anti-H pylori regimen should be prescribed taking sufficient time to instruct and motivate the patient.
