Typically, there is a delay in diagnosing dogs with Lyme disease. Based on their review of the literature, the authors summarized several reasons for this: “The first signs of clinical disease in dogs are non-specific, including fever, general malaise, lameness, and swelling of local lymph nodes. These symptoms are likely to be overlooked by dog […]

“We estimate that migratory birds disperse 50 million to 175 million I. scapularis [deer] ticks across Canada each spring, implicating migratory birds as possibly significant in I. scapularis range expansion in Canada,” wrote Ogen and colleagues¹ in their discussion of birds and Lyme disease. A study by Scott et al., however, finds that migratory songbirds,

Can Bell’s palsy lead to nonflaccid facial palsy in Lyme disease?. “Nonflaccid facial paralysis is a spectrum of hypokinetic and hyperkinetic movement,” wrote Markey and colleagues in the journal Otolaryngology.¹ Hypokinetic movement involves less movement, while hyperkinetic movement involves more movement. “Clinically, this manifests as contraction of the orbicularis oris muscle simultaneous with eye closure

The study, “Patient-reported outcome after treatment for definite Lyme neuroborreliosis” by Eikeland and colleagues, describes 258 patients treated for definite Neurologic Lyme disease. Many of them with chronic neurological lyme disease remained symptomatic an average of 5 years after their initial treatment. According to the authors, a higher proportion of their chronic neurological Lyme disease

The authors highlight the case of a 23-year-old woman who presented to their hospital “with a chief complaint of dyspnea and chest pain and was found to have a third degree AV-block on the electrocardiogram (ECG)” in their discussion of Lyme carditis symptoms. A temporary pacemaker was implanted. And after an exhaustive work-up for other

I can’t trust single-dose doxycycline to prevent Lyme disease. A perspective: A single 200 mg dose of doxycycline administered orally was reported to have been successfully used to prevent the development of erythema migrans at the bite site of Ixodes scapularis ticks,” writes Wormser in an article entitled “Doxycycline for Prevention of Spirochetal Infections-Status Report.”

Understanding how ticks move is important in developing ways to minimize our risk of tick bites and infection. As the authors point out, “less is known about the distances adult ticks are willing and able to travel in the short term and when a host is in close proximity.” The study looked at how adult

The retrospective review included 93 children with idiopathic Bell’s palsy to the University Hospital Southampton NHS Foundation Trust from 2010 to 2017. Idiopathic facial nerve palsy, formerly called Bell’s palsy, is seen in early Lyme disease. Very few children in the study with Bell’s palsy reported a tick bite or rash. In fact, only 14%

The clinic’s program to over Lyme disease treatment and its effectiveness are described in a recent article by Portman, “Implementing a pharmacist-run Lyme disease postexposure prophylaxis clinic augmented by academic detailing within the Veterans Health Administration.”¹ In April 2018, VA Butler Healthcare in Pennsylvania opened a pharmacist-run Lyme disease PEP clinic, known as PharmLD clinic.

The Canadian authors point out that in their country alone the number of Lyme disease cases has increased 14-fold over an 8 year period (2009-2017). They reviewed studies published between 1994 and 2019 to assess the extent of long-term sequelae due to Lyme disease. Based on eligibility criteria, 21 studies were included in the analysis,
