A review article by Hess and colleagues published in Sports Health explores the incident rate of Lyme arthritis in postoperative patients. One out of every three patients reports having arthritis as one of their initial symptoms of Lyme disease. In turn, a majority of patients are often first evaluated by orthopedic surgeons. Lyme arthritis, however, “has rarely been reported as a postsurgical complication.”
One would think that there would be substantial scientific evidence indicating the best treatment options for pregnant women who have a tick bite. Unfortunately, there is not. In their article, Smith and colleagues address the question: “If the health care provider decides to recommend antibiotic prophylaxis for a pregnant woman with a tick bite, what are the choices?” 
A dog can be man’s best friend, particularly when it comes to helping identify the risk of tick-borne diseases for humans. The true spread of Babesia may currently be underestimated, under-reported, and untreated, writes Mahachi and colleagues in the journal Parasites Vectors.¹ But new research indicates that hunting dogs can offer insight into the distribution of Babesia in the Southern and Western USA.
Some medical professionals and their patients have dismissed Lyme disease, believing the prevalence and potential damage a Lyme infection can cause is over-exaggerated. But what happens if your family is directly affected? A researcher from the University of Pennsylvania shares his story “Lemons and Lyme” in the Journal of the Pediatric Infectious Diseases Society.
Postural tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance which affects circulation or blood flow. It’s typically triggered when a person suddenly stands up after lying down. The primary symptoms include lightheadedness, fainting and an uncomfortable, rapid increase in heartbeat.
A recent article by Carriveau and colleagues recommends that a single dose of doxycycline should be prescribed to children following a tick bite to prevent Lyme disease.¹ Unfortunately, there is no evidence to support this recommendation.
Individuals with a weakened immune system are more susceptible to developing infections, such as COVID-19. A review study has also found that people with compromised immune systems are at a greater risk of developing disseminated Lyme disease. The authors of “Erythema Migrans: Course and Outcome in Patients Treated With Rituximab” investigated patients diagnosed with Lyme disease, who were also taking Rituximab, a medication known to impair immunity. 
In a recent editorial, Dr. Allen Steere describes the clinical features and proposed mechanisms triggering what he believes are 4 distinct post-treatment Lyme disease syndromes (PTLDS) in patients who fail antibiotic treatment for Lyme disease. 
Patients with Lyme disease are typically treated with a standard antibiotic, which may include doxycycline, amoxicillin, or cefuroxime, for a 2 to 4 week period. However, studies have shown that between 36-63% of treated patients continue to suffer with persistent symptoms. 
Dr. Daniel Cameron, MD, MPH, is a nationally recognized leader for his expertise in the diagnosis and treatment of Lyme disease and other tick-borne illnesses. For more than 30 years, he has been treating adolescents and adults suffering from Lyme disease.
