Severe Lyme carditis in an adolescent can present with life-threatening arrhythmias requiring emergency intervention. A 15-year-old boy with heart rate of 300 beats per minute and ventricular tachycardia needed multiple cardioversions and temporary pacing. Yet after antibiotic treatment, his heart block completely resolved and he remained symptom-free at one-year follow-up — demonstrating the reversible nature

Using data from Geisinger electronic medical records, researchers identified 9657 Lyme disease cases diagnosed between 2006 and 2014 in central and northeastern Pennsylvania. [bctt tweet=”Are African-Americans less likely to be diagnosed with Lyme disease?” username=”DrDanielCameron”] Only 1.4% of Lyme disease patients in central and northeastern Pennsylvania are African-American, according to a medical records review.

Now, a new study by Connally and colleagues examines the effectiveness of treated clothing after it is worn and washed/dried. [2] Does this impact the contact irritancy and toxicity against Ixodes scapularis nymphs? The investigators forced blacklegged ticks to be in contact with Permethrin-treated clothing for 30 to 120 seconds. They then monitored the ticks’

In their article “Searching for the Immature Stages of Ixodes scapularis in Leaf Litter and Soil in Texas,” Tietjen and colleagues, from Texas A&M University, speculate that nymphal ticks in the south could be in the leaf litter or in different soil layers rather than on the understory vegetation. [1] So, employing a different type

The 83-year-old man, from Pennsylvania, was admitted to the hospital, reporting pain in his knee, erythema and fever for 3 days. Upon examination, physicians noted he had “a moderate effusion and limited range of motion,” explains Collins. The patient had a total knee replacement, involving the same knee, 6 years earlier. Culture tests were negative

These conditions are typically thought to occur separately with several published reports describing each illness as mimicking the other. But a new article by Koester and colleagues details the first cases of acute Lyme and EBV infections reportedly occurring concurrently. “We describe the clinical presentation of two children with confirmed early Lyme disease and features
