Long-term results of macular pucker surgery

Response to treatment with antibiotics was compared with serologic reactivity and clinical symptoms in a pediatric population with presumptive diagnoses of Lyme borreliosis. The population analyzed for this study consisted of a subset of a larger Lyme clinic population being monitored as part of a prospective study on pediatric Lyme borreliosis. All patients resided in an area in which Ixodes scapularis and Borrelia burgdorferi are considered endemic. Serum from patients was tested by enzyme-linked immunosorbent assay and Western blotting. Response to antibiotics was evaluated by members of a pediatric Lyme clinic. Results showed that positive serologic test results correlate with a favorable response to antibiotics, as does the presence of erythema migrans (EM), regardless of serologic status. Seronegative patients without EM had chronic fatigue and arthralgia and/or myalgia as primary symptoms and did not respond to antibiotics, even when multiple courses of treatment were given. These results indicate that serologic tests designed to have high specificity can reliably rule out Lyme borreliosis in patients with chronic symptoms, thus preventing unnecessary treatment with antibiotics.     

Rheumatic manifestations in Lyme borreliosis: personal experience in patients with oligoarthritis of "unknown" origin

Lyme borreliosis is an infectious illness caused by the spirochete Borrelia burgdorferi and is transmitted by tick vectors. A prospective study was performed from January 1990, to investigate whether Lyme arthritis might have been undetected among patients with (unclassified arthritis) oligoarthritis of "unknown" aetiology. 210 patients were tested for antibodies to Borrelia burgdorferi: 82 patients with oligoarthritis of "unknown" aetiology; 52 patients with Reiter's syndrome; 20 patients with seronegative, B-27 positive oligoarthritis and 56 controls. Serological testing for Borrelia burgdorferi was performed by indirect immunofluorescence assay. The occurrence of positive antibodies (1:80) in 11 (13.4%) patients with arthritis of "unknown" aetiology was significantly different from the combined control group (1.6%) (p < 0.05). Four out of 11 patients remembered a tick bite, two out of 11 patients developed erythema migrans after 3 to 10 days. Six weeks later 2 patients developed oligoarthritis and one patient after a month. In the remaining 8 patients arthritis was the first sign of the disease. Knees were most commonly affected (90%). Radiographic abnormalities (osteoporosis, soft tissue swelling) were noted in 3 patients. The synovial fluid findings were typical for inflammatory arthritides in 6 patients. The diagnosis of Lyme borreliosis was made according to following data: origin from an area endemic for Lyme borreliosis, tick bite, erythema migrans, significant levels of the antibodies to the Borrelia burgdorferi and oligoarthritis. It can be concluded that arthritis may be the main manifestation of Borrelia burgdorferi infection.     

The Norwegian Polio Study 1994: a nation-wide survey of problems in long-standing poliomyelitis

BACKGROUND: Sarcoidosis is a multisystemic granulomatous disease of unknown etiology, while Lyme borreliosis is a multisystemic disorder caused by Borrelia burgdorferi. The purpose of this study is to evaluate the relationship between sarcoidosis and Lyme borreliosis in a region of Japan where Lyme borreliosis is endemic. METHODS: We determined the seroprevalence of anti-Borrelia burgdorferi antibodies as well as antibodies three Japanese Borrelia strains by enzyme-linked immunosorbent assay and dotblot assay using purified Borrelia-specific proteins in 46 patients with confirmed sarcoidosis and 150 controls (50 disease controls and 100 healthy controls) in Hokkaido, the affected region. RESULTS: Fifteen patients with sarcoidosis (32.6%) tested positive for Borrelia spirochete in both assays, compared with two disease controls (4.0%) and two healthy controls (2.0%). The seroprevalence of anti-Borrelia antibodies in patients with sarcoidosis was much higher in the affected region than in the region in our previous study were Lyme borreliosis is non-endemic. CONCLUSION: In a region where Lyme borreliosis is endemic, Borrelia infection may be partially associated with sarcoidosis.     

Psychiatric manifestations of Lyme borreliosis

BACKGROUND: Lyme borreliosis (Lyme disease), a tick-borne spirochetal illness, has later manifestations that may include arthritic, neurologic, ophthalmologic, and cardiac symptoms. Recent reports suggest psychiatric symptoms may also be part of the clinical picture. METHOD: Using a structured interview (SCID), we interviewed three patients who had developed a psychiatric disorder for the first time after infection with Borrelia burgdorferi. RESULTS: During Lyme borreliosis, one patient had major depression and panic disorder, one patient had an organic mood syndrome with both depression and mania, and the third patient had panic disorder. These disorders remitted after adequate antibiotic treatment. CONCLUSION: While depression has been previously linked to neuroborreliosis, this is the first report to link panic disorder and mania with borrelial infection. Because of the rapid rise of Lyme borreliosis nationwide and the need for antibiotic treatment to prevent severe neurologic damage, mental health professionals need to be aware of its possible psychiatric presentations.     

A new Borrelia species isolated from patients with relapsing fever in Spain

BACKGROUND: Lyme disease and tick-borne relapsing fever are worldwide systemic borrelioses caused by several Borrelia species transmitted by hard ticks (family Ixodidae) and soft ticks (family Argasidae), respectively. A previous seroepidemiological study of Lyme borreliosis showed several serologically reactive patients with clinically atypical presentations, and this discovery led to the hypothesis that some of the cases of Lyme borreliosis had been caused by another borrelia organism. METHODS: Blood from patients in southern Spain who had suspected Lyme disease or relapsing-fever borreliosis was cultured before treatment began. Isolates of Borrelia spp were inoculated into several strains of mice of different ages. The 16S rRNA and flagellin in genes of Borrelia spp were sequenced by PCR and assessed by phylogenetic analyses. FINDINGS: We isolated a species of Borrelia from three patients with relapsing fever and from Ornithodorus spp ticks in southern Spain. This organism (refractory to in-vitro cultivation) caused a relapsing spirochaetaemia with multiple organ involvement in laboratory mice that recreated the human disease. Phylogenetic analysis showed that this organism is a previously unrecognised species. INTERPRETATION: We have discovered a new borrelia pathogen that is closely related to the other tick-borne agents of relapsing fever in Europe and Africa, and which causes a relapsing systemic disease with serological similarities to Lyme borreliosis.     

Mitochondrial myopathy with predominant respiratory dysfunction in a patient with A3243G mutation in the mitochondrial tRNA(Leu(UUR))gene

Two treatment regimens for disseminated Lyme borreliosis (mainly neurologic and musculoskeletal manifestations) were compared in a randomized trial. A group of 30 patients received oral cefixime 200 mg combined with probenecid 500 mg three times daily for 100 days. Another group of 30 patients received intravenous ceftriaxone 2 g daily for 14 days followed by oral amoxicillin 500 mg combined with probenecid 500 mg three times daily for 100 days. There was no statistically significant difference in the outcome of infection between the two groups. However, the total number of patients with relapses or no response at all and the number of positive polymerase chain reaction findings after therapy were greater in the cefixime group. The general outcomes of infection in patients with disseminated Lyme borreliosis after 3-4 months of therapy indicate that prolonged courses of antibiotics may be beneficial in this setting, since 90% of the patients showed excellent or good treatment responses.     

Suppression of renin secretion in the isolated rat kidney by cycloheximide

Because 1,2:5,6-dianhydrogalactitol (NSC-132313 (DAG; the main conversion reaction product of the treatment of dibromodulcitol by mild akali or human serum) showed considerable antitumor activity in various mouse and rat tumor systems, a phase I study in 50 patients was conducted with five daily iv treatments repeated every 6 weeks. Thrombocytopenia was the dose-limiting toxicity. At a dose of 40 mg/m2/day for 5 days, the median platelet nadir was 31,000/mm3 and occurred on day 20; the plate count returned to normal within 8 days. At the same dose, the median white blood cell (WBC) nadir was 2,300/mm3 also on day 20-, the WBC count returned to normal within 7 days. Anemia, nausea, and vomiting were usually mild to moderate. No renal, hepatic, central nervous system, cardiac, or pulmonary toxicity was identified. Antitumor effects of DAG were observed in patients with renal, bladder, and small-cell lung cancers. An iv dose of 20-30 mg/m2/day for 5 consecutive days, repeated every 5-6 weeks, was recommended for phase II studies.     

Diagnostic tools in Lyme borreliosis: clinical history compared with serology

The occurrence of a history of clinical Lyme borreliosis and the prevalence of positive antibodies to Borrelia burgdorferi were studied in 431 Dutch hunters. The majority of the hunters (336 or 78%) did not report any complaints and had no positive IgG antibodies to B. burgdorferi. Sixty-five hunters (15.1%) had no clinical manifestations but did not have positive antibodies to B. burgdorferi. Only 1.9% of the population studied had had past symptoms of definite or probable Lyme borreliosis. Likelihood ratios were high (21.3) for the recognition of erythema migrans, but much lower for tick bites (3.6) or positive IgG Lyme serology (3.5). Clinical history turned out to be a more powerful diagnostic tool than Lyme serology.     

Cases of Lyme borreliosis resistant to conventional treatment: improved symptoms with cephalosporin plus specific beta-lactamase inhibition

We present four cases of verified late Lyme borreliosis with persistent symptoms and positive serology despite repeated courses of high-dose intravenous penicillin G and/or cephalosporins (including cefoperazone). The patients were now treated with cefoperazone 2 g plus sulbactam 1 g bid iv for 14 days. At the end of treatment, patients were symptom free and have remained so for the following 12 months. By then, IgG against Borrelia burgdorferi had decreased. It is concluded that the addition of beta-lactamase inhibitors to intravenous treatment could be beneficial in Lyme disease refractory to conventional treatment.     

Differential expression of Borrelia burgdorferi genes during erythema migrans and Lyme arthritis

Borrelia burgdorferi, the agent of Lyme disease, selectively expresses genes in the arthropod vector and mammalian host. Specific B. burgdorferi gene expression during human infection was examined in tissue specimens, using RNA-polymerase chain reaction, from 3 patients with Lyme disease. ospA was investigated because OspA is down-regulated by B. burgdorferi in ticks during engorgement and is a vaccine candidate in phase III clinical trials. p35 and p37 were also assessed because these genes are induced by spirochetes during murine Lyme borreliosis and play roles in protective immunity. p35 and p37 mRNA were detected in erythema migrans biopsy specimens from 2 patients and in the synovium of 1 patient with Lyme arthritis. ospA mRNA was not identified in any of these tissues. These data show that ospA is repressed while p35 and p37 are induced in human infection; these results are the first direct demonstration of differential B. burgdorferi gene expression during Lyme disease.     

Alkalinization and hemodialysis in severe salicylate poisoning: comparison of elimination techniques in the same patient

Difficulties in diagnosis of late stages of Lyme disease include low sensitivity of serological testing and late inclusion of Lyme disease in the differential diagnosis. Longer treatment modalities may have to be considered in order to improve clinical outcome of late disease stages. These difficulties clinical cases of Lyme borreliosis. The different clinical cases illustrate several aspects of late borreliosis: false negative serology due to narrow antigen composition of the used ELISA format, the need for prolonged antibiotic treatment in chronic or recurrent forms and typical presentations of late Lyme disease, such as lymphocytic meningo-encephalitis and polyradiculoneuritis.     

Ambulatory treatment with ceftriaxone in febrile neutropenic children

We conducted a prospective nonrandomized study of outpatient therapy with ceftriaxone as a single agent in 50 episodes of fever and neutropenia in children treated with various myelosuppressive regimens for different malignancies. All patients underwent clinical and radiological evaluation and blood/urine cultures taken before starting therapy. Patients with dehydration, hypotension, rigor and clinical exit-site infection of indwelling right-sided catheters were excluded. Forty-one patients completed an antibiotic course of 7 days: in 12 patients fever returned to normal on day 2, in 10 patients on day 3, and in 8 patients on day 4. The duration of neutropenia following the initial febrile episode was 3-10 days. In some patients fever returned to normal after 2 days, but neutropenia persisted up to 10 days. Two patients were bacteremic--Escherichia coli in one, and Acinetobacter/Staphylococcus coagulase negative in another; all isolates were sensitive to ceftriaxone. In nine episodes, antimicrobial therapy was modified because of persistent fever > 39 degrees C in five patients, bacteremia in two, enterocolitis in one, breakthrough fever in two, and bronchopneumonia in one. The low incidence of bacterial isolation is probably attributed to the selection of patients with low risk features. Patients and parents complied with and favored outpatient therapy to hospitalization.     

Ankle arthrodesis with cross screw fixation. Good results in 36/40 cases followed 3-7 years

From May 1991 to May 1994, Lyme borreliosis was studied prospectively in 301 residents living on Asp?, a highly endemic area for the disease. The study included annual questionnaires and blood samples for serology. Immunoglobulin G (IgG) antibodies to Borrelia burgdorferi sensu lato were detected by enzyme-linked immunosorbent assay in 63/301 (21%) of the residents at the start of the study. Seropositivity rates increased with time, and 3 years later 101/301 (34%) were positive. A total of 34 individuals developed physician-verified manifestations of Lyme borreliosis during the study period. Nine individuals developed an erythema migrans, despite a previously treated Lyme borreliosis or pre-existing high levels of IgG antibodies to B. burgdorferi s.l.     

Acrodermatitis chronica atrophicans in an 11-year-old girl

We report a case of acrodermatitis chronica atrophicans in an 11-year-old girl living in an area endemic for Lyme borreliosis. The diagnosis was first made on the basis of clinical, histopathological and serological findings. Moreover, Borrelia burgdorferi-specific DNA was amplified from lesional skin by polymerase chain reaction. Intravenous treatment with ceftriaxone (2 g once daily) for 2 weeks was initiated. The skin changes clearly responded to the therapy, and Borrelia burgdorferi-specific gene segments were no longer detectable by polymerase chain reaction. This is the first report of molecular-proven acrodermatitis chronica atrophicans in childhood. The occurrence of this late skin manifestation of Lyme borreliosis in children is reviewed.     

Isolated lymphadenopathy as manifestation of the early stage of Lyme borreliosis

The paper reports 4 cases of early Lyme borreliosis which presented as lymphadenopathy at the site of the tick bite. Erythema migrans and dissemination of infection were absent. The diagnosis was verified via diagnostic titer of antibodies to Borrelia. Administration of antibiotics at the stage of lymphadenopathy contributed to better prognosis. One patient did not receive antibacterial treatment in acute disease and had progression with infection dissemination. Regional lymphadenopathy may serve a clinical marker of early Lime borreliosis.     

Severe atrioventricular block in 2 cases with pre-excitation syndrome

In two patients with WPW syndrome Type A suffering from syncopes and dizziness intermittent high degree A-V block was observed. The analysis of the surface Ecg revealed in the first case a complete A-V block within the normal conduction system at the level of the A-V node. In the second case there was a constant left bundle branch block with intermittent block in the right fascicle (intermittent trifascicular block). In both cases the preexcitation syndromes could be best explained by accessory tracts bypassing the normal nodal system left side. One-to-one conduction through the bypass occurred only at a distinct range of cycle lengths, at lower frequencies the accessory tracts were refractory and a IInd or IIIrd degree A-V block occurred. However, outside this frequency zone some P waves were conducted through the accessory tracts without changes in cycle lengths. The findings support the thesis of at least two functionally different atrioventricular pathways in patients with preexcitation syndrome.     

Sj?gren''s syndrome presenting with a minor salivary gland mass

To survey the frequency of Lyme borreliosis (LB) and to evaluate its clinical presentation in Europe, we performed a questionnaire interview of a sample of physicians involved in the care of patients with LB. Reference laboratories in 15 European countries agreed to participate by distributing questionnaires to those clinicians who most frequently requested LB serology for their patients. The mean number of cases of LB per physician per country showed a longitudinal geographical gradient, with a higher number of patients seen in Eastern and Central Europe than in Western Europe. Skin involvement was seen in 58.9% of the patients, neurological involvement in 34.3%, joint involvement in 15.4% and cardiac involvement in 2%. About 30% of the patients had multisystem involvement. The frequency of the different manifestations varied greatly between countries. The frequency of diagnosis of LB and the number of serological tests requested were inversely correlated.     

A case of tick bite by a spontaneously retreated Ixodes nipponensis

A 58-year old housewife consulted us about 1 cm sized, dark-brownish, bean-like mass which was dropped spontaneously from indurated skin lesion on her abdomen. The mass was identified morphologically as an engorged female Ixodes nipponensis. Nine days earlier, she had an excursion collecting edible sprouts of wild grass. Spontaneous retreat has been unusual in clinical tick bites in Korea. Fourteen cases of tick bite described in the Korean literature were reviewed briefly in relation to Lyme borreliosis.     

Temporal study of immunoglobin M seroreactivity to Borrelia burgdorferi in patients treated for Lyme borreliosis

Forty-six patients with late Lyme disease who were considered improved or cured following treatment were monitored by immunoglobin M (IgM) immunoblotting (mean monitoring period, 27.6 months). There was a persistent IgM response in 32 (97%) of 33 initially positive patients. All but three showed a consistent number, type, and intensity of IgM bands over the entire follow-up period. IgM immunoblotting may not be useful for monitoring the response to treatment of Lyme borreliosis.
