1/11. optic nerve lesion following neuroborreliosis: a case report.PURPOSE: Neuroborreliosis may cause various neuro-ophthalmological complications. We describe a case with a bilateral optic neuropathy. CASE REPORT: A 58-year-old female developed facial paresis six weeks after an insect bite. One week later she developed bilateral optic disc swelling with haemorrhages and nerve fibre bundle defects in the lower visual field of the left eye. In CSF and serum, raised IgM and IgG titres to borrelia burgdorferi were found. Systemic antibiotic treatment led to improvement of the vision and facial paresis, but not all visual field defects resolved, probably due to ischemic lesions of the optic disc. DISCUSSION/CONCLUSIONS: In optic nerve lesions due to neuroborreliosis it is difficult to distinguish between inflammatory and ischemic lesions. This patient demonstrated features of an ischemic optic nerve lesion.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
2/11. Concurrent infection of the central nervous system by borrelia burgdorferi and bartonella henselae: evidence for a novel tick-borne disease complex.OBJECTIVES: To investigate bartonella henselae as a potential human tick-borne pathogen and to evaluate its role as a coinfecting agent of the central nervous system in the presence of neuroborreliosis. DESIGN: Case report study. SETTING: A primary health care center in Flemington, NJ, and the Department of research and Development at Medical Diagnostic laboratories LLC in Mt Laurel, NJ. SUBJECTS: Two male patients (aged 14 and 36 years) and 2 female patients (aged 15 and 30 years, respectively) with a history of tick bites and lyme disease. MAIN OUTCOME MEASURES: Laboratory and diagnostic findings before and after antimicrobial therapy. RESULTS: patients residing in a Lyme-endemic area of new jersey with ongoing symptoms attributed to chronic lyme disease were evaluated for possible coinfection with Bartonella species. Elevated levels of B henselae-specific antibodies were found in these patients using the immunofluorescent assay. bartonella henselae-specific dna was detected in their blood. None of these patients exhibited the clinical characteristics of cat-scratch disease. Findings of cerebrospinal fluid analysis revealed the presence of both B henselae- and borrelia burgdorferi-specific dna. bartonella henselae-specific dna was also detected in live deer ticks obtained from the households of 2 of these patients. CONCLUSIONS: Our data implicate B henselae as a potential human tick-borne pathogen. patients with a history of neuroborreliosis who have incomplete resolution of symptoms should be evaluated for B henselae infection.- - - - - - - - - - ranking = 780.8195429069keywords = tick bite, tick, bite (Clic here for more details about this article) |
3/11. Large cerebral vessel occlusive disease in lyme neuroborreliosis.We report on a 12-year-old, previously healthy girl with an acute hemiparesis as the predominant clinical manifestation of lyme neuroborreliosis (LNB). The diagnosis of LNB was based on cerebrospinal fluid (CSF) studies, laboratory findings and the clinical course whereas the patient's history and the lack of characteristic skin lesions obscured the diagnosis in the beginning. After four weeks of antibiotic and physiotherapeutic treatment, the hemiparetic symptoms had completely resolved. Although evidence of vasculitic and perivascular inflammation in LNB has been described in the literature, large cerebral vessel occlusive disease represents a rare finding. Appropriate treatment strategies can lead to good clinical rehabilitation, as shown in this case, making the timely diagnosis a crucial issue. We conclude that LNB should be considered in every stroke-like episode of unknown origin in children, even in the absence of a history of a tick bite or typical skin lesions.- - - - - - - - - - ranking = 510.79541278195keywords = tick bite, tick, bite (Clic here for more details about this article) |
4/11. Double infection with tick borne encephalitis virus and borrelia burgdorferi sensu lato.The limited information on co-infection with borrelia burgdorferi sensu lato and tick-borne encephalitis (TBE) virus was a stimulus for presentation of two patients with well-defined double infection of the central nervous system. TBE virus and B. burgdorferi sensu lato infections are searched for in all patients with lymphocytic meningitis and/or meningoencephalitis admitted to our department. During the last ten years we identified two patients who had ELISA IgM and IgG antibodies to TBE virus in serum and a positive PCR result for TBE virus in cerebrospinal fluid as well as B. burgdorferi sensu lato isolated from cerebrospinal fluid. Intrathecal production of borrelial antibodies was not proven in either of the two patients. These findings show that in patients with acute lymphocytic meningitis originating in regions endemic for Lyme borreliosis and TBE, the possibility of concomitant infection should be considered.- - - - - - - - - - ranking = 192.16009294639keywords = tick (Clic here for more details about this article) |
5/11. pain as presenting symptom in lyme neuroborreliosis.Neurogenic pain with radiculitis is often the starting symptom in adult patients with tick-borne lyme neuroborreliosis and in some cases the only clinical manifestation. Cranial paresis and other neurologic signs usually occur after the onset of pain. The present paper describes four patients who had severe pain as the main presenting symptom of lyme neuroborreliosis. Opioids had good short-term effect in two of the cases. Oral doxycycline treatment was used successfully to eliminate the infection.- - - - - - - - - - ranking = 38.432018589278keywords = tick (Clic here for more details about this article) |
6/11. lyme disease and the peripheral nervous system.lyme disease, the multisystem infectious disease caused by the tick-borne spirochete borrelia burgdorferi, causes a broad variety of peripheral nerve disorders, including single or multiple cranial neuropathies, painful radiculopathies, and diffuse polyneuropathies. Virtually all appear to be varying manifestations of a mononeuropathy multiplex. diagnosis requires that the patient should have had possible exposure to the only known vectors, ixodes ticks, and also have either other pathognomonic clinical manifestations or laboratory evidence of exposure. Treatment with antimicrobial regimens is highly effective. The mechanism underlying these neuropathies remains unclear, although interactions between anti-Borrelia antibodies and several peripheral nerve constituent molecules raise intriguing possibilities.- - - - - - - - - - ranking = 76.864037178555keywords = tick (Clic here for more details about this article) |
7/11. fluorine-18-labeled fluorodeoxyglucose-positron emission tomography studies of acute brainstem lyme neuroborreliosis [corrected] Case report.The authors report on a patient suffering from acute Lyme borreliosis who underwent two consecutive [18F]fluorodeoxyglucose-positron emission tomography (FDG-PET) studies demonstrating the course of the disease. The first FDG-PET study revealed markedly increased glucose metabolism in the brainstem, matching exactly the signal abnormalities exhibited on magnetic resonance images and indicating a brainstem tumor. A second PET scan demonstrated no abnormality in this region, thus reflecting clinical remission following antibiotic therapy. Data in the present case indicate that hypermetabolic findings on FDG-PET studies in the brainstem region should be regarded with caution and that neuroborreliosis must be considered as a possible differential diagnosis.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
8/11. Painful hallucinations and somatic delusions in a patient with the possible diagnosis of neuroborreliosis.Neuroborreliosis has become the most frequently recognized tick-borne infection of the nervous system in europe and the united states. In addition to dermatological, cardiac, articular, and neurologic manifestations, psychiatric disorders such as depression, panic attacks, and schizophrenia-like psychosis can also arise. We report on a 61-year-old woman who developed a severe pain syndrome following several tick bites. She was diagnosed with neuroborreliosis; she received various courses of antibiotics over several years, but without any clinical improvement in her condition. Her eventual admission to a psychiatric ward due to mental symptoms and neuroleptic treatment led to a dramatic improvement of her pain symptoms. However, increasing delusions disclosed a psychotic episode, which ceased over time. We discuss therapeutic difficulties and psychiatric complications in the absence of a clear-cut diagnosis of neuroborreliosis. Although this patient might have suffered from late-onset schizophrenia with painful hallucinations right from the start of her disease, the case highlights psychiatric complications that might be associated with neuroborreliosis.- - - - - - - - - - ranking = 549.22743137123keywords = tick bite, tick, bite (Clic here for more details about this article) |
9/11. Lyme borreliosis in portugal caused by Borrelia lusitaniae? Clinical report on the first patient with a positive skin isolate.BACKGROUND: Borrelia lusitaniae was isolated from an ixodes ricinus tick in portugal in 1993 for the first time. Further, this borrelia genospecies has been found in ixodid ticks collected around the coasts of southern portugal and North africa. Its reservoir has not been defined yet. B. lusitaniae was isolated once until now from a patient with a long standing and expanding skin disorder. PATIENT AND methods: A 46-year-old Portuguese woman presented with a skin lesion on the left thigh which had evolved slowly over ten years. The patient reported limb paraesthesias, cramps, chronic headaches, and cardiac rhythm disturbances. history of tick bites was negative nor had the patient ever noticed a skin lesion comparable with erythema chronicum migrans. skin biopsies were taken for histological evaluation, culture and dna detection. antibodies to borrelia were searched by indirect immunofluorescence assay and Western-blot. RESULTS: A bilateral carpal tunnel syndrome and local synovitis was diagnosed. Dermato-histology was normal, serology was negative. Spirochaetal organisms were cultured from a skin biopsy and identified as B. lusitaniae. The patient improved after a 2-week course of intravenous ceftriaxone; the skin lesions did not expand further. CONCLUSIONS: This culture confirmed skin infection by B. lusitaniae in a patient from portugal suggests an additional human pathogen out of the B. burgdorferi sensu lato complex in europe, particularly in portugal.- - - - - - - - - - ranking = 587.65944996051keywords = tick bite, tick, bite (Clic here for more details about this article) |
10/11. Paralytic strabismus as a manifestation of lyme borreliosis.lyme disease is a multi-system organ disorder caused by borrelia burgdorferi. Although ocular manifestations have been reported, these remain a rare feature of the disease. This report shows a 49-years old patient that has been bitten by a tick and as consequence of which developed symptoms of the lyme disease. In 1998 the patient was hospitalized in our Eye Clinic due to operating treatment of the paralytic strabismus (abductal nerve paralysis), as a rare feature of the lyme disease. Postoperative squint angle was significantly reduced, but without any temporal movement. diplopia was still present, though slightly reduced with the use of prism eyeglasses. The improvement of the quality of life was achieved, as well as the patient's satisfaction.- - - - - - - - - - ranking = 38.432018589278keywords = tick (Clic here for more details about this article) |
