Lyme disease is an infectious disease caused by a spirochete of the Borrelia sensu lato group. Its incidence has greatly increased in recent years. The main vector is a tick of the Ixodes family. Clinical manifestations are multiple and show the multi-organ character of the disease. In terms of frequency, joint and neurological presentations, respectively more frequent in North America and Europe, are the main manifestations after cutaneous symptoms, of which erythema migrans is the most common, followed by cardiac and ocular signs. Other signs exist but are anecdotal. Neuroborreliosis manifests itself most often with peripheral facial palsy, but there are other clinical forms, which include acute myelitis (4-5% of neuroborreliosis). We present here the case of a 16-year-old teenager with acute myelitis and meningeal involvement due to Lyme disease, who presented with atypical symptoms (massive and rapid weight loss, vomiting). MRI showed localized marrow edema as well as leptomeningeal and root enhancement. Lumbar puncture showed lymphocytic pleocytosis. Lyme serology was positive both in blood and cerebrospinal fluid. Even if acute myelitis remains exceptional among neuroborreliosis manifestations, this diagnosis has to be thought of when a child presents with unexplained neurological symptoms.

Described in 1962, the opsoclonus-myoclonus-ataxia syndrome (OMAS) is a rare, neurologically debilitating disorder with distinct characteristics that may begin in childhood or adult life. Although many cases remain without etiological diagnosis, others are related to neoplasms and infectious diseases. We report a 41-year-old previously healthy male with an 8-day history of headache, vertigo, nausea, vomiting, and nystagmus. After a normal brain computed tomography and lymphocytic pleocytosis in cerebral spinal fluid (CSF), intravenous acyclovir therapy was initiated in the emergency room. On the third day of hospitalization, the diagnosis of OMAS was made based on the presence of chaotic and irregular eye movements, dysarthric speech, gait instability, generalized tremor, and myoclonic jerks. In the face of his neurological worsening, ampicillin followed by nonspecific immunotherapy (methylprednisolone and intravenous immunoglobulin) was prescribed, with mild clinical improvement. After a thorough laboratory workup, the definite diagnosis of neuroborreliosis was established and ceftriaxone (4 g/daily/3 wks) and doxycycline (200 mg/day/2 mo) was administered. Toward the end of the ceftriaxone regimen, the neurologic signs substantially improved. We believe this to be the first case description of OMAS as clinical presentation of Brazilian Lyme disease-like syndrome (Baggio-Yoshinari syndrome).

Babesiosis is an emerging tick-borne disease transmitted by the hard tick Ixodes scapularis, which also transmits Lyme disease. Better gradation of prognostic indicators are needed to determine which patients may develop serious complications requiring hospitalization, and to provide early guidance on appropriate therapy. In this study, we evaluated 128 patients with smear or real time polymerase chain reaction-confirmed Babesia microti infections over a period of 16 years. Patients with asplenia or immunocompromising conditions were more likely to have severe infection (P < 0.01), require hospitalization (P < 0.01), or receive prolonged courses of antimicrobials (P < 0.01). Nausea or vomiting (P < 0.01) and diarrhea (P < 0.01) along with hyperbilirubinemia (P < 0.01) were predictive of severe infection, hospitalization, and prolonged antimicrobial therapy. Patients with concurrent Lyme disease were less likely to require hospitalization and had similar severity of disease and length of antibiotic treatment compared with those without Lyme disease.
