Impact of patient age on clinical features, serologic test reactivity and long-term outcome of culture-confirmed early Lyme disease.

Whether age at time of diagnosis impacts the clinical presentation or long-term outcome of early Lyme disease is unknown. Subjects enrolled in this study had culture-confirmed early Lyme disease and were followed up annually in a long-term prospective study. Subjects ≤50years of age were compared with those who were ≥51years of age at time of study entry.

Comparison of males versus females with culture-confirmed early Lyme disease at presentation and at 11-20 years after diagnosis.

Background: Lyme disease is the most common vector-borne infection in the United States with 300,000 estimated cases per year.

Objective: The purpose of this study was to compare the presenting clinical features and long-term outcome of males versus females with culture-confirmed early Lyme disease.

Methods: 174 males and 109 females with culture-confirmed erythema migrans were entered into a prospective study with follow-up visits scheduled at six months, 12 months and annually thereafter for up to 20 years.

Long-term Assessment of Post-Treatment Symptoms in Patients With Culture-Confirmed Early Lyme Disease.

Background: Lyme disease patients with erythema migrans are said to have post-treatment Lyme disease symptoms (PTLDS) if there is persistence of subjective symptoms for at least 6 months following antibiotic treatment and resolution of the skin lesion. The purpose of this study was to characterize PTLDS in patients with culture-confirmed early Lyme disease followed for >10 years.

Methods: Adult patients with erythema migrans with a positive skin or blood culture for Borrelia burgdorferi were enrolled in a prospective study beginning in 1991 and followed up at 6 months and annually thereafter to determine the long-term outcome of this infection.

The O'Neill grading system for evaluation of the tympanic membrane: A practical approach for clinical hyperbaric patients.

Eustachian tube dysfunction (ETD) and middle ear barotrauma (MEB) are the two most common complications of clinical hyperbaric oxygen (HBO2) treatment. The current grading system, the Teed's Classification, was first described in 1944 with modifications to this system over the years, but none are specific for the evaluation and treatment of patients undergoing clinical HBO2 therapy. Currently, the standard of care is a baseline otoscopic examination performed prior to starting HBO2 therapy.

Long-term assessment of health-related quality of life in patients with culture-confirmed early Lyme disease.

The health-related quality of life of 100 subjects with culture-confirmed early Lyme disease enrolled in a prospective study with annual follow-up visits was evaluated using the 36-Item Short Form General Health Survey version 2 (SF-36v2) questionnaire at 11-20 years after diagnosis. The mean summary scores of physical and mental health were similar to those of the general population.

Long-Term Assessment of Fibromyalgia in Patients with Culture-Confirmed Lyme Disease.

Background: Fibromyalgia occurs in 2% to 8% of the general population. One of the triggers may be Lyme disease. Methods: Patients with culture-confirmed Lyme disease who originally presented with erythema migrans have been evaluated annually in a prospective study to determine their long-term outcome.

Long-term assessment of fatigue in patients with culture-confirmed Lyme disease.

Background: Fatigue is a common symptom with numerous causes. Severe fatigue is thought to be an important manifestation of post-treatment Lyme disease syndrome. The frequency with which severe fatigue occurs as a long-term sequela in prospectively followed patients with Lyme disease is unknown.
