Ticks and the changing landscape of tick borne illnesses

Ticks and the diseases they carry have long been recognized as health concerns, especially in the warmer months when ticks (and humans) are more active. Ticks wait on grass tips or shrubs to latch onto new hosts when they brush by. Most of the hosts are animals, but a few tick species do bite and feed on humans. While doing so, they can transmit bacteria and viruses through their saliva. But here’s what’s changing: Tick species are being found in a wider geographic range. The number of case reports of tick-borne illnesses is increasing. Scientists continue to identify new pathogens (bacteria and viruses that cause disease) transmitted by ticks. Many of these infections are reportable diseases on a state or national level, meaning that physicians and laboratories must notify public health officials of cases to facilitate tracking. Improved reporting may contribute to the increase in the number of cases, or perhaps doctors are testing more for infections that previously went undiagnosed, but it also appears that a greater percentage of ticks are now harboring certain pathogens. Ticks as vectors (that is, carriers of disease) Not all ticks are vectors (carriers) of disease, but those that are tend to spread specific infections; for example, the common deer tick transmits the bacteria that causes Lyme disease. Like all organisms, certain types of ticks tend to thrive in specific environments. The Centers for Disease Control and Prevention has maps showing regions wh...

Authors: Teixeira JC, Jackson PJ Abstract Distinguishing between central and peripheral causes of vertigo can be challenging not only in an acute setting but also in chronic settings. A thorough review of systems and physical exam can assist providers in differentiating central versus peripheral etiologies and the need for urgent imaging. In this case, a 47-year-old man presented with vertigo, right-sided hearing loss, right-sided headache, and right-sided facial pain that began 4 weeks before while the patient was on a cruise ship. His physical exam findings were notable for anisocoria with right pupil 3.5 an...

The malformations of cortical development (most FCD) were the most common pathological type for children cases in China with drug ‐resistant seizures. It was speculated further that the FCD patients with shorter duration of epilepsy before surgery seem to have a higher ratio of being seizure‐free after surgery. AbstractObjectivesThe drug ‐resistant seizures are characterized by frequent and severe onset of seizures in childhood. There is only little literature had extensively explored the types of pathological brain damage in Chinese children cases. The present study aims to investigate the histopathologic findings a...

AbstractAerophagia is a functional gastrointestinal disorder characterized by excessive swallowing of air associated with abdominal distension and pain, flatulence, belching, nausea, and vomiting. The purpose of the current study was to evaluate the effectiveness of an antecedent-based behavioral intervention on aerophagia with an adolescent female diagnosed with Lennox-Gastaut syndrome (LGS), severe intellectual disability, and herpes simplex virus infection of the central nervous system with chronic static encephalopathy. Results from a functional analysis and multiple-component aerophagia assessment suggested that aerop...

The management of obstetric patients, who are admitted to a general intensive care unit, can often be accompanied by a fair share of apprehension owing to the intricacy of care. Rather than discussing common obstetric emergencies and their management, we would like to call attention to bas...
