Investigators question the term “Australian Lyme”
In their paper, “Characterising DSCATT: A case series of Australian patients with debilitating symptom complexes attributed to ticks,” Schnall and colleagues question the use of the term “Australian Lyme.” [1] And prefer instead to refer to this condition as Debilitating Symptom Complexes Attributed to Ticks (DSCATT).
What parts of the body do ticks prefer to bite?
Do all tick species have the same attachment/biting preference? Does an infected tick attach to or bite different areas vs. non-infected? Does a tick’s life stage impact where it attaches? Investigators examined the biting behavior of several tick species collected from New York State in hopes of answering these questions.
Does Lyme disease affect the brain?
Rheumatologists often see patients complaining of joint pain, some of whom may live in Lyme-endemic regions. However, as the authors of a new study point out, “Today, Lyme disease with true arthritis occurs far less than cases with arthralgias and neurologic features.”
Lyme disease or dementia?
In the article entitled “A Case of Reversible Dementia? Dementia vs Delirium in Lyme Disease,” Sanchini et al. present a case which highlights the importance of having a diagnostic approach to dementia to identify and treat reversible causes. [1]
Abnormal MRI leads to Lyme encephalitis diagnosis
Encephalitis is a rare manifestation of Lyme disease with brain parenchymal inflammation being documented in only a handful of cases. In this study, the authors present the case of Lyme neuroborreliosis with encephalitis with “significant parenchymal inflammation on MRI imaging in an immunosuppressed patient.” [1]
Borrelia miyamotoi infection: An emerging tick-borne disease in California
Borrelia miyamotoi has been detected in various species of Ixodes ticks including I. ricinus in Europe, I. scapularis in eastern North America, and I. pacificus in western North America.
In California, the I. pacificus tick can harbor 2 types of spirochetes (Borrelia miyamotoi and Borrelia burgdorferi) capable of causing Borrelia miyamotoi infection and Lyme disease.
Is SOT an effective treatment for Lyme disease?
Supportive Oligonucleotide Therapy (SOT), also called Antisense Oligonucleotide Therapy (ASOT), is currently being used to treat viral infections, some cancers and Lyme disease.
Tick control methods not effective in residential neighborhoods
Controlling tick populations can help reduce the likelihood of individuals being bitten by an infected tick and developing a tick-borne illness, such as Lyme disease.
Multiple types of tick control methods have been employed but with varying degrees of success. This study explores the effectiveness of bait boxes and the biopesticide spray Met52 in reducing tick abundance and tick encounters with humans.
Lyme carditis patients may require temporary permanent pacemaker
Lyme carditis can cause atrioventricular (AV) block, which may present with varying degrees of severity. Some of these patients may require a pacemaker but doctors are typically reluctant to prescribe a permanent pacemaker, since symptoms will often resolve with antibiotic treatment.
Can skin color affect medical students’ ability to diagnose Lyme disease?
Multiple studies have demonstrated that a patient’s race can affect the diagnostic tests offered to that patient. One study found African American patients who presented with chest pain were offered fewer tests than non-African Americans, according to Dodd and colleagues. [1]
