Arthritis is a well-known manifestation of Lyme disease. And although studies have detected Borrelia burgdorferi (Bb) by culture and PCR in bone and marrow of humans and dogs,¹ little is known about the effects of Bb infection on bone tissue, outside articular surfaces.
In their article, “Lyme Carditis in Hospitalized Children and Adults, a Case Series,” Shen and colleagues compare, for the first time, the presentation, management, and outcomes of Lyme carditis in the pediatric versus adult populations.
In their article, entitled “Neuropsychiatric and Psychological Symptoms in Patients with Lyme Disease: A Study of 252 Patients,” Hündersen and colleagues describe the clinical presentation, diagnostic process and treatment regimens for 252 Lyme disease patients. 
A case report by Weise and colleagues demonstrates that Lyme disease can induce temporomandibular joint (TMJ) pain and may be misdiagnosed as a common temporomandibular disorder (TMD).
Several studies have described patients with Lyme disease as suffering from dementia-like symptoms, including brain fog, memory loss and confusion. In 2018, researchers reported the case of an 80-year-old man with neuroborreliosis who was almost misdiagnosed with dementia.  Meanwhile, singer/songwriter Kris Kristofferson, initially diagnosed with Alzheimer's disease, was later found to have Lyme disease.
In their article, “Postural orthostatic tachycardia syndrome (POTS) and other autonomic disorders after COVID-19 infection: a case series of 20 patients,” the authors describe 15 patients with a new onset of autonomic dysfunction following a COVID-19 infection. 
What is Borrelia miyamotoi? This tick-borne illness, transmitted by deer ticks, is believed to be underrecognized and a growing concern, as studies indicate a B. miyamotoi infection may be as common as anaplasmosis and babesiosis. Researchers randomly tested 250 individuals living in Manitoba, Canada and found that 10% were seropositive for B. miyamotoi. 
Babesia can be a severe and life-threatening tick-borne illness. In a recent article, Dr. Gary Wormser described a 61-year-old female with an untreated Babesia microti infection.¹ The woman’s IgM test for Lyme disease was positive, but it was dismissed as a false positive test.
Small fiber neuropathy (SFN) is a disorder that affects the small sensory cutaneous nerves, resulting in unusual sensations such as tingling, pins-and-needles and numbness. Some patients may experience burning pain or coldness and electric shock-like brief painful sensations. In most patients, these symptoms start in the feet and progress upwards.¹
Human babesiosis is a potentially life-threatening parasitic infection, typically transmitted through a tick bite. Babesia microti (B. microti) and Babesia duncani (B. duncani) are two red blooded parasites known for causing babesiosis. But, this is the first report of a different species, Babesia odocoilei, causing illness in humans.
