Number of post-treatment Lyme disease cases expected to soar

The number of post-treatment Lyme Disease (PTLD) cases is expected to soar, according to the authors of a new study, “Estimation of cumulative number of post-treatment Lyme disease cases in the US, 2016 and 2020.”

Lyme carditis presenting as atrial fibrillation treated successfully

Lyme carditis is known to cause symptoms of fatigue, difficulty or labored breathing (dyspnea), palpitations, lightheadedness, syncope, and chest pain. [1] But as this case report demonstrates, symptoms can sometimes be atypical. The authors describe a patient with Lyme carditis presenting as atrial fibrillation, a type of arrhythmia that causes the heart to beat much faster than normal.

Human bite leads to discovery of Asian longhorned ticks in New York

Asian longhorned ticks, which have been known to feed mainly on farm animals, particularly cattle, can transmit deadly diseases. In Asia, the longhorned ticks have infected humans with the potentially fatal disease SFTS (severe fever and thrombocytopenia syndrome). As of yet, no cases have been reported in the United States.

Study explores the risk of tick bites among German military personnel

Military personnel are at a particularly high risk of contracting a tick-borne disease, as they spend the majority of their time outdoors and in heavily forested areas. A new study, by Sammito and colleagues, looks at the risk of tick bites among individuals in the military stationed in northern Germany.

5 cases of Lyme arthritis following an operation

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.”

Neurological damage/dysfunction found in early Lyme disease patients

If Borrelia burgdorferi spirochete, the bacteria causing Lyme disease, can infect the brain and disrupt functioning of the central nervous system, it may also alter cerebral metabolism, suggests Garkowski and colleagues in the Journal of Neurology’s May 2019 issue.

Growing list of cardiac problems in Lyme disease

“Lyme disease affects all layers of the heart and every part of the conducting system,” writes Kannangara and colleagues in the journal BMC Infectious Diseases. [1] The authors came to this conclusion following treatment of a 37-year-old male with inducible heart block (HB).

Infected deer ticks moving into New York City

In 2017, New York City (NYC) health officials released an advisory, warning clinicians to be on alert for patients who may exhibit symptoms of a tick-borne disease. According to the notice, Staten Island, a borough of NYC, had a significant number of locally acquired Lyme disease cases. [1]

Getting the diagnosis correct and avoiding ‘anchor bias’

‘Anchor bias’ can occur when a doctor makes decisions based on the initial information (anchor) provided and in turn, misses the correct diagnosis. For example, a patient may be diagnosed with chronic fatigue syndrome, fibromyalgia, migraines or a mood disorder because the physician focused on the first information and missed the diagnosis of Lyme disease.
