A recent study by Wells and colleagues ¹ confirms findings from previous studies which demonstrated that POTS patients with brain fog have impaired short-term memory and diminished alertness. POTS is characterized by a substantial increase in heart rate and sometimes a drop in blood pressure when the individual stands up. This can cause lightheadedness, heart […]

Hess and colleagues discuss 5 cases, reported in the literature, in which Lyme arthritis following an operation. [1] Case 1 The first case they cite involved a 38-year-old woman who had undergone knee surgery. She had a “bone-patellar tendon-bone reconstruction of her anterior cruciate ligament along with a staged autologous chondrocyte transplantation to repair a

In the journal Cureus , Tahir and colleagues describe the symptoms and treatment of POTS,¹  a condition often seen in Lyme disease, which causes the heart rate to rise by at least 30 beats per minute for adults and at least 40 points for children “when the person stands up from a recumbent position.” The

The authors cite studies with “high-level evidence” recommending prophylaxis treatment of tick bites during pregnancy with a single dose of 200 mg of doxycycline. The risk, they say, to the unborn baby is low. “Previously, doxycycline was avoided in pregnancy and in children under 8 years of age because of concerns about adverse effects similar

Investigators looked at several tick-transmitted diseases including Babesia, in dogs, to help determine potential risks to humans. Hunting dogs, specifically, were tracked as they are exposed to ticks more often than pet dogs. And they are more likely to be outdoors for long periods in tick habitats and less likely to be groomed for ticks

“One day, when traveling in California for a meeting, I received a call informing me that one of my sons, then aged 39, had been walking his dog when he collapsed into unconsciousness with a heart rate of 35/minute and had been taken to a local hospital,” writes Plotkin.¹ A Lyme infection was suspected. His

Patients with autoimmune disorders are at risk for POTS, along with individuals who have had a viral illness or a serious infection, such as Lyme disease. In fact, POTS and Lyme disease patients often present with similar symptoms. For instance, POTS patients frequently report having “brain fog,” also a common complaint among Lyme disease patients.

The authors reference a small study to support their recommendation for using a single doxycycline dosage for Lyme disease prevention. The study, conducted by Drs. Fish, Nadelman and Wormser, however, involved adults, not children. ² And it was designed to demonstrate that a single dose of doxycycline could prevent an erythma migrans (EM) rash. It

A small study examined the risk of developing disseminated Lyme disease for people with weakened immune systems. Researchers enrolled 7 patients with an EM (erythema migrans) rash who were diagnosed with Lyme disease. In these 7 patients, signs of disseminated LB (43%) and the isolation rates of borreliae from blood before antibiotic treatment (40%) were
