12/22. subarachnoid hemorrhage due to borrelia burgdorferi-associated vasculitis.We report the case history of a patient who suffered a subarachnoid hemorrhage (SAH) in association with early lyme neuroborreliosis. After a tick bite, this patient developed erythema chronicum migrans and complained of stinging radicular pain in both legs. A computed tomography (CT) scan was performed because of acute headache and nuchal rigidity, which revealed an occipital SAH. cerebrospinal fluid analysis provided further evidence of acute neuroborreliosis. Digital substraction angiography showed irregularities in the right posterior cerebral artery, which might be due to vasculitis, but no aneurysms.- - - - - - - - - - ranking = 251.15504095505keywords = burgdorferi (Clic here for more details about this article) |
13/22. Tick inoculation in an eyelid region: report on five cases with one complication of the orbital myositis associated with Lyme borreliosis.PURPOSE: To determine the frequency and dependence of Lyme borreliosis after tick infestation in the eyelid region. MATERIAL AND methods: Five patients after tick inoculation were investigated by immunofluorescence assays for IgM and IgG system). Ophthalmologic evaluation of myositis was supported with MRI, laboratory, and internal clinical investigations. RESULTS: Four children showed negative Borrelia serology after a bite from a tick. In one case the left abducens nerve palsy was found, which was diagnosed in MRI as a thickened left lateral rectus muscle. The diagnosis of myositis with positive borrelia burgdorferi serology was consistent with Lyme borreliosis. Other laboratory examinations were negative. The symptoms were reduced after treatment with ceftriaxon. CONCLUSIONS: Lyme borreliosis was found in one in five patients after tick infestation in the eyelid region. antibiotic prophylaxis against Lyme borreliosis with ampicillin is recommended for children after a tick bite.- - - - - - - - - - ranking = 62.788760238763keywords = burgdorferi (Clic here for more details about this article) |
14/22. borrelia burgdorferi myelitis presenting as a partial stiff man syndrome.Eight weeks after a tick bite, a 33-year-old male patient presented with stiffness of one leg together with spasmodic painful jerks resembling stiff man syndrome. Isolated myelitis of lumbosacral segments of the spinal cord, apparently confined to the grey matter, was diagnosed and its spirochaetal aetiology confirmed by serology and CSF findings. Oligoclonal IgG bands in CSF specific for borrelia burgdorferi were found. Thus, there is evidence that B. burgdorferi ist able to cause a localized myelitis, probably of spinal interneurons, presenting as a partial stiff man syndrome.- - - - - - - - - - ranking = 376.73256143258keywords = burgdorferi (Clic here for more details about this article) |
15/22. lyme disease in italy: first reported case.The AA describe the first italian case of lyme disease in a middle aged woman: the patient developed after a tick bite the classical erythema chronicum migrans lesions and one month later an oligoarthritis. By indirect immunofluorescence assay it has been found a significant titre compatible with an infection by borrelia burgdorferi, the causative agent of lyme disease.- - - - - - - - - - ranking = 62.788760238763keywords = burgdorferi (Clic here for more details about this article) |
16/22. Reinfection in erythema migrans disease.Two patients received oral penicillin for erythema migrans disease (EMD) in 1973 and 1977. Five and seven years later, respectively, they developed EMD for a second time after being bitten by ticks. The first and second erythema migrans lesions appeared in different places. Tests of sera evaluated for antibodies to borrelia burgdorferi before (in one case), during and after the second episode of EMD remained negative (patient 1) or yielded an at least four-fold rise of IgG antibody titers, but did not become positive (patient 2). These cases provide evidence that reinfection in EMD may occur without a significant elevation of specific antibody titers.- - - - - - - - - - ranking = 62.788760238763keywords = burgdorferi (Clic here for more details about this article) |
17/22. The use of surface immunofluorescence assay (SIFA) in the microbiological diagnosis of Lyme borreliosis: a case report.In this report we describe the use of a newly developed immunofluorescence technique performed with living spirochetes to detect serum antibody to B. burgdorferi s.l. in a case of early Lyme borreliosis. The immunofluorescence method used (surface immunofluorescence assay: SIFA) proved useful in the serological evaluation of suspected cases of lyme disease.- - - - - - - - - - ranking = 62.788760238763keywords = burgdorferi (Clic here for more details about this article) |
18/22. Cultivation of borrelia burgdorferi from human tick bite sites: a guide to the risk of infection.BACKGROUND: The risk of acquiring lyme disease has been evaluated by xenodiagnostic procedures with laboratory strains of borrelia burgdorferi and laboratory-reared ixodes ticks, or by clinical trials in which diagnosis was based on clinical findings, culture, or serologic tests. OBJECTIVE: Our purpose was to determine the risk of infection from tick bites in a natural setting in which wild strains of B. burgdorferi were involved, by a biopsy culture technique. methods: skin biopsy specimens were obtained from ixodes scapularis tick bite sites, processed, and examined for the presence of B. burgdorferi. RESULTS: B. burgdorferi was cultivated from only 2 of 48 skin biopsy specimens. In both instances duration of tick attachment was approximately 24 hours. CONCLUSION: In a hyperendemic region for lyme disease the risk of infection after a deer tick bite appears to be low, particularly if the tick has been attached for less than 24 hours.- - - - - - - - - - ranking = 502.31008191011keywords = burgdorferi (Clic here for more details about this article) |
19/22. The histologic spectrum of hepatic cat scratch disease. A series of six cases with confirmed bartonella henselae infection.Cat scratch disease (CSD), a common cause of regional lymphadenitis, has been linked to bartonella henselae infection. Although rare, dissemination with hepatic involvement has been documented. Six cases of hepatic CSD were retrieved and probed for B. henselae dna. hematoxylin-eosin, trichrome, methenamine silver, Gram, Ziehl-Neelsen, and Warthin-Starry stained slides were reviewed by all authors, and the histologic findings were recorded. B. henselae infection was confirmed in all cases using combined polymerase chain reaction and Southern blot methods. All biopsies contained multiple granulomas, many with characteristic stellate abscesses surrounded by three distinct zones: an inner layer of palisading histiocytes, an intermediate lymphocytic rim, and an outermost zone of fibrosis. One case had noncaseating granulomas with prominent giant cells. Warthin-Starry stains were positive in two. The surrounding parenchyma in all cases contained lymphocytic infiltrates within expanded fibrotic portal triads and adjacent dilated sinusoids. There is a distinct spectrum of histologic changes in hepatic CSD. Although the unit lesion is granulomatous, the organization varies markedly. All cases show predictable nonspecific surrounding parenchymal changes. When multiple hepatic lesions are found in patients with constitutional symptoms suggesting an infectious illness, CSD should be included in the differential diagnosis.- - - - - - - - - - ranking = 1keywords = lyme (Clic here for more details about this article) |
20/22. Acute urticaria caused by pigeon ticks (argas reflexus).A 28-year-old man was admitted to our institute because of acute urticaria appearing a few hours earlier. The patient stated that during sleep he had been bitten by a large number of "insects," which had dropped from wooden ceiling beams under the roof of his room. The patient was living in the center of Milan in a very old house, where numerous pigeons had built their nests under the rooftop. The patient brought along with him some examples of these "insects," which were later classified as pigeon ticks (argas reflexus) (Figs. 1,2). Dermatologic examination revealed the presence of numerous wheals and erythemato-papular lesions on the neck and trunk. These lesions were of different shapes and sizes, bright red in color, and with a small central ulceration corresponding to the tick bite. In addition, there were numerous excoriated lesions due to scratching; the patient in fact complained of very intense pruritus. The general physical examination was within normal limits. Laboratory examinations revealed only slight leukocytosis (9300 WBC/mm3). All other laboratory tests were negative; in particular, the assay for anti-borrelia burgdorferi IgG and IgM was within normal ranges (< 1:256 and < 1:64, respectively). These results were confirmed on subsequent blood samples. Positive radioallergosorbent tests (RAST) to a somatic extract and to the saliva of the tick were observed. A diagnosis of acute urticaria caused by A. reflexus was made. The patient was treated with betamethasone (4 mg intravenously) and chlorpheniramine (10 mg intramuscularly), with resolution of the clinical picture within 3 days.- - - - - - - - - - ranking = 62.788760238763keywords = burgdorferi (Clic here for more details about this article) |
