Reversible atrioventricular block and the importance of close follow-up: Two cases of Lyme carditis

Publication date: Available online 13 February 2018 Source:Journal of Cardiology Cases Author(s): Anthony H. Kashou, Nabil Braiteh, Hisham E. Kashou Lyme carditis is an uncommon presentation of the early-disseminated phase of Lyme disease, although it is recognizable and often curable. Because of its rarity, diagnosing Lyme carditis requires a high level of suspicion, especially when young patients in certain endemic areas present with symptoms of bradycardia and/or evidence of high-degree atrioventricular (AV) block. Temporary cardiac pacing along with antibiotic therapy has been shown to aid in the management of Lyme carditis until symptoms and conduction blocks have resolved. Herein, we report two cases of Lyme carditis-induced AV block that were successfully managed and reversed with temporary cardiac pacing and antibiotics. In order to monitor for any late sequela that may arise, we also recommend close follow-up for patients treated for Lyme carditis with high-degree AV block. <Learning objective: Lyme carditis manifests as a conduction system disease, predominantly involving the atrioventricular (AV) node. It can present without the classical signs of Lyme disease. It is critical to have a high suspicion of Lyme carditis in patients who present with symptoms of bradycardia or high-degree AV block in high prevalence areas. Early initiation of antibiotics, along with external temporary pacing, dramatically improves mortality rates. Close follow-up is important in pat...

Purpose: The South Bohemian Region of the Czech Republic is an endemic area of tick-borne encephalitis (TBE). In 2017, the inhabitants of Římov municipality developed a serious course of TBE and Lyme borreliosis (LB). This led experts to research and serology examinations of the inhabitants of Římov in order to detect the seroprevalence of TBE and LB.

We report 2 cases of severe babesiosis initially mistaken as malaria. The first patient was complicated by shock and splenic infarction, the other co-infected with Lyme disease. As the population traveling abroad increases every year, physicians should be aware of babesiosis which mimics malaria, co-infection with other diseases, and its complications.

Purpose of review To review the clinical diagnosis, management and natural history of septic arthritis of the hip (SAH) in the pediatric patient, and to highlight new information that may improve the management of these patients. Recent findings The basics of management of possible pediatric SAH have remained largely unchanged for generations. New questions have been raised regarding the role and timing of advanced imaging (MRI) in the evaluation of patients with possible SAH. Published criteria have been derived to guide the need for MRI studies in these patients. Validation of these guidelines continues. Recent revi...

We describe a rare case of a 56-year-old previously healthy male who presented with thoracic paresthesias and hyperesthesias involving the T6-11 dermatomes several weeks after a febrile illness. A thoracic MRI demonstrated a T7-10 transverse myelitis and an exhaustive evaluation revealed neuroborreliosis. His symptoms improved significantly after an initial steroid course and 21 day course of ceftriaxone. We review neuroborreliosis and summarize the features of 23 previously reported cases of Lyme myelopathy. Although Lyme myelopathy is rare, including Lyme in the differential diagnosis of an acute transverse myelitis work...

Publication date: Available online 14 December 2018Source: Ticks and Tick-borne DiseasesAuthor(s): George Psevdos, Teresa Khoo, Robert Chow, Christopher L Romano, Scott CampbellAbstractIn North America, Lyme disease (LD) is caused predominantly by the spirochete Borrelia burgdorferisensu stricto, and is transmitted by blacklegged ticks. Long Island, New York, is highly endemic for the disease. The C6 peptide (C6P) is currently used as a screening test for LD in our institution. Our objective was to examine how screening with C6P concorded with diagnosis of LD at the Veterans Affairs Medical Center, Northport, Long Island. ...

RauerAbstractAbout 5–20% of the general population in endemic areas have seroprevalence for anti-borrelial antibodies. Previous studies have shown a high rate of 25–97% of persisting anti-borrelial antibodies in patients with treated Lyme neuroborreliosis (LNB) at follow-up. These studies used immunoblots with antigens from whole-cell sonicates, which could be less specific than modern recombinant antigens. We assessed the seroprevalence of...
