Point of Care Ultrasound as a Diagnostic Tool to Detect Small Bowel Obstruction in the Emergency Department: A Case Report.

Unlabelled: Point of Care Ultrasound (POCUS) in the Emergency Department (ED) is a rapidly evolving field and has improved time to diagnose and management. POCUS of the bowel is still a novel concept for many departments. However, there is a potential application for POCUS to augment or replace traditional diagnostic imaging of small bowel obstruction (SBO).

The impact of strain-specific immunity on Lyme disease incidence is spatially heterogeneous.

Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common tick-borne infection in the US. Recent studies have demonstrated that the incidence of human Lyme disease would have been even greater were it not for the presence of strain-specific immunity, which protects previously infected patients against subsequent infections by the same B. burgdorferi strain.

Identification of spp. from Cardiac Tissue by 16S rRNA PCR in a Patient with Culture-Negative Device-Associated Endocarditis: A Case Report and Review of the Literature.

The genus was recently distinguished from other actinomycetes such as . While these organisms are known to be distributed widely in the environment, over the past decade several novel species have been described and isolated from human clinical specimens. Here we describe the identification of by PCR amplification and sequencing of the 16S rRNA encoding gene from cardiac tissue in a patient with culture-negative device-associated endocarditis.

Public health impact of strain specific immunity to Borrelia burgdorferi.

Background: Lyme disease, caused by Borrelia burgdorferi, is the most common tick-borne infection in the United States. Although humans can be infected by at least 16 different strains of B. burgdorferi, the overwhelming majority of infections are due to only four strains.

Long-term Assessment of Post-Treatment Symptoms in Patients With Culture-Confirmed Early Lyme Disease.

Background: Lyme disease patients with erythema migrans are said to have post-treatment Lyme disease symptoms (PTLDS) if there is persistence of subjective symptoms for at least 6 months following antibiotic treatment and resolution of the skin lesion. The purpose of this study was to characterize PTLDS in patients with culture-confirmed early Lyme disease followed for >10 years.

Methods: Adult patients with erythema migrans with a positive skin or blood culture for Borrelia burgdorferi were enrolled in a prospective study beginning in 1991 and followed up at 6 months and annually thereafter to determine the long-term outcome of this infection.

Erythema migrans.

Erythema migrans (EM) is the most common objective manifestation of Borrelia burgdorferi infection. Systemic symptoms are usually present. Most patients do not recall a preceding tick bite.

Long-term assessment of health-related quality of life in patients with culture-confirmed early Lyme disease.

The health-related quality of life of 100 subjects with culture-confirmed early Lyme disease enrolled in a prospective study with annual follow-up visits was evaluated using the 36-Item Short Form General Health Survey version 2 (SF-36v2) questionnaire at 11-20 years after diagnosis. The mean summary scores of physical and mental health were similar to those of the general population.

A computer-based automated reminder increases the percentage of urinary catheters justified by an order and increases urinary catheter discontinuation orders.

Use of an automated reminder for an order to continue or to discontinue a urinary catheter resulted in a significant increase in the percentage of urinary catheters justified by an order and the percentage of urinary catheter discontinuation orders increased. This is an essential first step toward reducing inappropriate urinary catheter use.

Long-Term Assessment of Fibromyalgia in Patients with Culture-Confirmed Lyme Disease.

Background: Fibromyalgia occurs in 2% to 8% of the general population. One of the triggers may be Lyme disease. Methods: Patients with culture-confirmed Lyme disease who originally presented with erythema migrans have been evaluated annually in a prospective study to determine their long-term outcome.

Long-term assessment of fatigue in patients with culture-confirmed Lyme disease.

Background: Fatigue is a common symptom with numerous causes. Severe fatigue is thought to be an important manifestation of post-treatment Lyme disease syndrome. The frequency with which severe fatigue occurs as a long-term sequela in prospectively followed patients with Lyme disease is unknown.

Evidence for strain-specific immunity in patients treated for early lyme disease.

Lyme disease, caused by Borrelia burgdorferi, is the most commonly reported vector-borne disease in the United States. Many patients treated for early Lyme disease incur another infection in subsequent years, suggesting that previous exposure to B. burgdorferi may not elicit a protective immune response.

Differences and similarities between culture-confirmed human granulocytic anaplasmosis and early lyme disease.

Lyme disease is transmitted by the bite of certain Ixodes ticks, which can also transmit Anaplasma phagocytophilum, the cause of human granulocytic anaplasmosis (HGA). Although culture can be used to identify patients infected with A. phagocytophilum and is the microbiologic gold standard, few studies have evaluated culture-confirmed patients with HGA.

Differentiation of reinfection from relapse in recurrent Lyme disease.

Background: Erythema migrans is the most common manifestation of Lyme disease. Recurrences are not uncommon, and although they are usually attributed to reinfection rather than relapse of the original infection, this remains somewhat controversial. We used molecular typing of Borrelia burgdorferi isolates obtained from patients with culture-confirmed episodes of erythema migrans to distinguish between relapse and reinfection.

Single-tier testing with the C6 peptide ELISA kit compared with two-tier testing for Lyme disease.

For the diagnosis of Lyme disease, the 2-tier serologic testing protocol for Lyme disease has a number of shortcomings including low sensitivity in early disease; increased cost, time, and labor; and subjectivity in the interpretation of immunoblots. In this study, the diagnostic accuracy of a single-tier commercial C6 ELISA kit was compared with 2-tier testing. The results showed that the C6 ELISA was significantly more sensitive than 2-tier testing with sensitivities of 66.

Comparison of five diagnostic modalities for direct detection of Borrelia burgdorferi in patients with early Lyme disease.

Lyme disease, the most commonly reported tick-borne infection in North America, is caused by infection with the spirochete Borrelia burgdorferi. Although an accurate clinical diagnosis can often be made based on the presence of erythema migrans, in research studies microbiologic or molecular microbiologic confirmation of the diagnosis may be required. In this study, we evaluated the sensitivity of 5 direct diagnostic methods (culture and nested polymerase chain reaction [PCR] of a 2-mm skin biopsy specimen, nested PCR and quantitative PCR (qPCR) performed on the same 1-mL aliquot of plasma and a novel qPCR-blood culture method) in 66 untreated adult patients with erythema migrans.

The amber theory of Lyme arthritis: initial description and clinical implications.

Lyme arthritis differs in many respects from other bacterial causes of arthritis. Based on an observation made for a patient with Lyme arthritis, we propose that the pathogenesis of joint swelling in Lyme arthritis is due to the introduction into the joint space of non-viable spirochetes or more likely spirochetal debris enmeshed in a host-derived fibrinous or collagenous matrix. This "amber" hypothesis can account for the clinical and laboratory features of Lyme arthritis and is amenable to experimental validation.

Antiscience and ethical concerns associated with advocacy of Lyme disease.

Advocacy for Lyme disease has become an increasingly important part of an antiscience movement that denies both the viral cause of AIDS and the benefits of vaccines and that supports unproven (sometimes dangerous) alternative medical treatments. Some activists portray Lyme disease, a geographically limited tick-borne infection, as a disease that is insidious, ubiquitous, difficult to diagnose, and almost incurable; they also propose that the disease causes mainly non-specific symptoms that can be treated only with long-term antibiotics and other unorthodox and unvalidated treatments. Similar to other antiscience groups, these advocates have created a pseudoscientific and alternative selection of practitioners, research, and publications and have coordinated public protests, accused opponents of both corruption and conspiracy, and spurred legislative efforts to subvert evidence-based medicine and peer-reviewed science.

Quantitation of cell-associated borrelial DNA in the blood of Lyme disease patients with erythema migrans.

Bloodstream invasion is an important event in the pathogenesis of the more serious manifestations of Lyme disease. The number of spirochetes in the blood of infected patients, however, has not been determined, and, therefore, it is unknown whether the number of spirochetes can be correlated with particular clinical or laboratory features. This study was designed to measure the level of Borrelia burgdorferi in the plasma of Lyme disease patients and correlate these levels with selected clinical and laboratory findings.

Prospective evaluation of 2009 H1N1 influenza A in patients admitted with fever to an oncology unit.

We prospectively evaluated all oncology inpatients for 2009 H1N1 influenza virus. All patients recovered completely. Evaluating all oncology patients with fever for influenza involved overtreatment of influenza-negative patients and involved a significant infection control burden.

Comparison of erythema migrans caused by Borrelia burgdorferi and Borrelia garinii.

Background: A comparison of patients with erythema migrans due to Borrelia garinii versus Borrelia burgdorferi has not been reported.

Patients And Methods: One hundred nineteen patients from New York State with erythema migrans caused by B. burgdorferi were compared with 116 patients from Slovenia with erythema migrans due to B.

Babesiosis in Lower Hudson Valley, New York, USA.

Although Lyme disease has been endemic to parts of the Lower Hudson Valley of New York, United States, for >2 decades, babesiosis has emerged there only since 2001. The number of Lower Hudson Valley residents in whom babesiosis was diagnosed increased 20-fold, from 6 to 119 cases per year during 2001-2008, compared with an ≈1.6-fold increase for the rest of New York.

Scientific evidence and best patient care practices should guide the ethics of Lyme disease activism.

Johnson and Stricker published an opinion piece in the Journal of Medical Ethics presenting their perspective on the 2008 agreement between the Infectious Diseases Society of America (IDSA) and the Connecticut Attorney General with regard to the 2006 IDSA treatment guideline for Lyme disease. Their writings indicate that these authors hold unconventional views of a relatively common tick-transmitted bacterial infection caused by the spirochete Borrelia burgdorferi. Therefore, it should come as no surprise that their opinions would clash with the IDSA's evidence-based guidelines for the diagnosis and treatment of Lyme disease.

Efficacy of antibiotic prophylaxis for the prevention of Lyme disease: an updated systematic review and meta-analysis.

Background: The clinical value of antibiotic prophylaxis in preventing Lyme disease remains uncertain, owing to a meta-analysis lacking sufficient power to demonstrate efficacy and a more recent trial showing effectiveness but lacking precision. Our objective was to update our prior meta-analysis on antibiotic prophylaxis for the prevention of Lyme disease, to obtain a more precise estimate of treatment effect.

Methods: Clinical trials were identified by searching MEDLINE, Embase, the Cochrane Library and trial registries, and by an assessment of the bibliographies of retrieved articles and reviews.
