Twelve out of 28 children with Lyme disease evaluated at an academic medical center in the Netherlands remained ill with post-treatment Lyme borreliosis syndrome (PTLBS). These 12 children presented with various complaints, including fatigue, general malaise and pain. There were no other medical explanations for their complaints and all were positive for Borrelia burgdorferi sl based on two-tier testing of C6-Lyme enzyme immunoassay (EIA) and IgG/IgM immunoblots. 
Babesia, a severe, potentially life threatening illness, has been identified in as many as 40% of individuals with Lyme disease in the North Eastern USA. The clinical spectrum now includes what has been described as “asymptomatic.” This is particularly concerning given that the infection can be acquired not only through a tick bite but through blood transfusions.
In his review of autonomic dysfunction due to infectious diseases, Artal from the Neurology Department at Raigmore Hospital in the UK, writes, “Complex regional pain syndromes [CRPS] and reflex sympathetic dystrophy with regional sympathetic hyperactivity have also been reported in some patients with Lyme disease.”  CRPS is characterized by considerable pain (allodynia, hyperalgesia), edema, trophic changes of the skin and muscles and sudomotor disorders.
Numerous studies have found that wearing permethrin-treated clothing can reduce the risk of tick bites. A University of Rhode Island study found that people wearing permethrin-treated sneakers and socks were 73.6 times less likely to have a tick bite than those wearing untreated footwear.  But very few studies have looked at the behavior of a tick when it comes in contact with permethrin-treated clothing. Does it climb onto the insecticide-soaked textile or avoid it entirely? Does permethrin actually kill ticks?
Over the past ten years, there have been 75 cases of Powassan virus reported in the United States, according to the Centers for Disease Control and Prevention (CDC).  Most cases have been confined to the Northeast and Great Lakes region. That, however, may change. As Lyme disease continues to spread throughout the country, so too may this potentially deadly virus.
Are pet owners more at risk of being bitten by a tick? Yes, according to a study in the journal Zoonoses Public Health.  The risk is significantly higher for both dog and cat owners. Jones and colleagues looked at 2,727 households in three Lyme disease-endemic states. More than half (56.7%) reported owning an indoor-outdoor pet, either a dog and/or cat.
Doctors have for many years recognized neuropsychiatric complications of Lyme disease with more than 340 journal articles addressing an association between psychiatric symptoms and Lyme and associated diseases. This study is, however, the first comprehensive assessment of suicidality, specifically, in patients with tick-borne illnesses.
Uveitis, or inflammatory eye disease that produces swelling and destroys tissue, remains an uncommon but serious complication of Lyme disease. In the British Medical Journal, Bernard and colleagues from Croix Rousse University Hospital, Lyon, France, describe seven cases of Lyme-associated uveitis. 
Guillain-Barre Syndrome (GBS) is a life-threatening illness in which the body's immune system attacks the peripheral nervous system. It's characterized by a rapid onset of muscle weakness which can lead to respiratory distress and death. The initial symptoms are typically tingling and weakness in the feet and legs. The exact cause is unknown, but GBS is usually preceded by an infectious illness such as a respiratory infection or stomach flu. While many infections have been associated with GBS, Borrelia burgdorferi, the pathogen causing Lyme disease, has rarely been connected with the syndrome. According to a study by Patel and colleagues, only four cases have been reported in the literature. 
Surveillance data from Wisconsin published in the Morbidity and Mortality Weekly Report (MMWR) demonstrates the seriousness and warranted concern over the spread of the tick-borne disease, Babesia. In 1985, the first case of Babesiosis in Wisconsin was documented. The disease became officially reportable in the state in 2001. Since then, the number of individuals contracting the disease has soared.
