Abstract
Lyme endocarditis is extremely rare manifestation of Lyme disease. The clinical manifestations of Lyme endocarditis are non-specific and can be very challenging diagnosis to make when it is the only manifestation of the disease. Until now, only a few cases where reported. Physicians should keep in mind the possibility of borrelial etiology of endocarditis in endemic areas. Appropriate valve tissue sample should be sent for histopathology, culture, and PCR especially in case of endocarditis of unknown origin PCR on heart valve samples is recommended. With more frequent PCR, Borrelia spp. may be increasingly found as a cause of infective endocarditis. Prompt diagnosis and treatment of Lyme carditis may prevent surgical treatment and pacemaker implantations. Due to climate change and global warming Lyme disease is a growing problem. Rising number of Lyme disease cases we can expect and rising number of Lyme endocarditis.

Abstract
Lyme carditis is a rare cardiac manifestation of Lyme disease that occurs when bacterial spirochetes infect the pericardium or myocardium triggering an inflammatory response. The most common electrocardiogram (EKG) findings in these patients include atrioventricular (AV) conduction abnormalities (first, second, and third degree heart block). A 56-year-old male with a history of hypothyroidism, from the Northeastern region of the United States, presented to the emergency department with lightheadedness and chest pain. His EKG revealed sinus bradycardia with a heart rate of 49 beats per minute, without ST segment elevation, T wave inversions, or signs of heart block. An enzyme-linked immunosorbent assay (ELISA) Lyme titer was elevated, and confirmatory Western blot was positive for IgG and negative for IgM. He was treated with intravenous (IV) ceftriaxone; however, he continued to have persistent bradycardia with his heart rate dropping to 20 to 30 beats per minute throughout the night. Additionally, he had several sinus pauses while sleeping, with the longest lasting for 6.1 seconds. A pacemaker and an additional three-week course of IV ceftriaxone was determined to be the best treatment for his resistant bradycardia secondary to Lyme carditis. No symptoms were present at his one month follow-up appointment, as an outpatient, after completing ceftriaxone therapy. The patient follows up with cardiology regularly to have his pacemaker checked. Here we present a unique case of Lyme carditis, without the classical findings of Lyme disease or common EKG findings of AV conduction abnormalities. A high clinical suspicion of Lyme carditis is required when someone from a Lyme endemic region presents with unexplained cardiac symptoms and electrocardiogram abnormalities. This case report aims to add to the knowledge gap between suspicion of Lyme carditis and sinus bradycardia as the only presenting symptom.

Abstract
BACKGROUND The clinical course of children with advanced heart block secondary to Lyme disease has not been well characterized. OBJECTIVE To review the presentation, management, and time to resolution of heart block due to Lyme disease in previously healthy children. METHODS An IRB approved single-center retrospective study was conducted of all patients < 21 years old with confirmed Lyme disease and advanced second or third degree heart block between 2007 and 2017. RESULTS Twelve patients (100% male) with a mean age of 15.9 years (range 13.2-18.1) were identified. Six patients (50%) had mild to moderate atrioventricular valve regurgitation and all had normal biventricular function. Five patients had advanced second degree heart block and 7 had complete heart block with an escape rate of 20-57 bpm. Isoproterenol was used in 4 patients for 3-4 days and one patient required transvenous pacing for 2 days. Patients were treated with 21 days (n = 6, 50%) or 28 days (n = 6, 50%) of antibiotics. Three patients received steroids for 3-4 days. Advanced heart block resolved in all patients within 2-5 days, and all had a normal PR interval within 3 days to 16 months from hospital discharge. CONCLUSION Symptomatic children who present with new high-grade heart block from an endemic area should be tested for Lyme disease. Antibiotic therapy provides quick and complete resolution of advanced heart block within 5 days, while steroids did not appear to shorten the time course in this case series. Importantly, no patients required a permanent pacemaker.

Abstract
Carditis is a common manifestation of adult patients with Lyme disease affecting 4-10% of Lyme patients in the United States. However, children with Lyme disease rarely present with acute carditis. The management of pediatric patients with complete heart block (CHB) secondary to Lyme carditis has not been well described. We report the acute management of 2 pediatric patients that presented in CHB secondary to Lyme disease.

Abstract
Viruses are the most common cause of myocarditis in economically advanced countries. Enteroviruses and adenoviruses are the most common etiologic agents. Viral myocarditis is a triphasic process. Phase 1 is the period of active viral replication in the myocardium during which the symptoms of myocardial damage range from none to cardiogenic shock. If the disease process continues, it enters phase 2, which is characterized by autoimmunity triggered by viral and myocardial proteins. Heart failure often appears for the first time in phase 2. Phase 3, dilated cardiomyopathy, is the end result in some patients. Diagnostic procedures and treatment should be tailored to the phase of disease. Viral myocarditis is a significant cause of dilated cardiomyopathy, as proved by the frequent presence of viral genomic material in the myocardium, and by improvement in ventricular function by immunomodulatory therapy. Myocarditis of any etiology usually presents with heart failure, but the second most common presentation is ventricular arrhythmia. As a result, myocarditis is one of the most common causes of sudden death in young people and others without preexisting structural heart disease. Myocarditis can be definitively diagnosed by endomyocardial biopsy. However, it is clear that existing criteria for the histologic diagnosis need to be refined, and that a variety of molecular markers in the myocardium and the circulation can be used to establish the diagnosis. Treatment of myocarditis has been generally disappointing. Accurate staging of the disease will undoubtedly improve treatment in the future. It is clear that immunosuppression and immunomodulation are effective in some patients, especially during phase 2, but may not be as useful in phases 1 and 3. Since myocarditis is often selflimited, bridging and recovery therapy with circulatory assistance may be effective. Prevention by immunization or receptor blocking strategies is under development. Giant cell myocarditis is an unusually fulminant form of the disease that progresses rapidly to heart failure or sudden death. Rapid onset of disease in young people, especially those with other autoimmune manifestations, accompanied by heart failure or ventricular arrhythmias, suggests giant cell myocarditis. Peripartum cardiomyopathy in economically developed countries is usually the result of myocarditis.

Abstract
Lyme disease is a vector-borne illness that can affect numerous organ systems during the early disseminated phase, including the heart. The clinical course of Lyme carditis is usually benign with most patients recovering completely. In rare instances, death from Lyme carditis has been reported. The cardinal manifestation of Lyme carditis is conduction system disease, which generally is self-limited. Heart block occurs usually at the level of the atrioventricular node but often is unresponsive to atropine sulfate. Temporary pacing may be necessary in more than 30% of patients, but permanent heart block rarely develops. Myocardial and pericardial involvement can occur but generally is mild and self-limited. Diagnosis is made by associating the clinical and historical features of borreliosis, such as previous tick bite, EM, or neurologic involvement, with electrocardiographic abnormalities and symptoms such as chest pain, palpitations, syncope, and dyspnea. Serologic studies and endomyocardial biopsy can support the diagnosis in the correct clinical setting, and MR imaging, echocardiography, and gallium scanning have utility in selected circumstances. No treatment has been shown clearly to attenuate or prevent the development of Lyme carditis, but mild carditis generally is treated with oral antibiotics and severe carditis with intravenous antibiotics in an effort to eradicate the infection and prevent late complications of Lyme disease. There is conflicting evidence regarding the role that B. burgdorferi plays in the development and progression of chronic congestive heart failure. Because of the significant false-positive ELISA rate in this population and the unclear benefit of antibiotic therapy, confirmatory Western blot analysis is recommended. Routine therapy and screening of patients with idiopathic dilated cardiomyopathy is of limited utility and should be reserved for patients with clear history of antecedent Lyme disease or tick bite.

Abstract
BACKGROUND Borrelia Burgdorferi (BB) induces cardiac conduction abnormalities in infected humans. Mice models of Lyme disease have been developed, however their electrophysiologic (EP) properties of conduction are unknown. METHODS Seventy-six C3H/J mice (BB infected and age- and gender-matched controls) underwent blinded in vivo EP studies. In a first phase of the study, 40 male C3H/J mice were divided into 2 groups: Group (A) mice were infected at age 3 (weeks) and studied at 5, and Group (B) mice were infected at 9 and studied at 11. In a second phase, 36 female mice were divided into 2 groups: Group (C) mice were infected at 3 weeks and studied at 5, and Group (D) mice were infected at 3 and studied at 11. RESULTS Infected mice of group (A) and (C) had wider QRS complexes (21.0+/-1.6 versus 17.3+/-1.3ms, p< or =0.0001 and 20.3+/-2.1 versus 18.5+/-1.7, p = 0.05, respectively) compared to the healthy controls (HC). Infected mice of group (B) and group (D) were similar to the HC. In all groups, the presence of conduction abnormalities correlated very closely with the amount of inflammation on pathology. CONCLUSION This study describes the first EP mouse model of Lyme carditis. C3H/J mice exhibit conduction abnormalities that are reversible 8 weeks after inoculation, closely paralleling the resolution of inflammation on pathology. This model can be a valuable tool in the developing and testing of new modalities for the prevention and treatment of Lyme carditis.

Abstract
We conclude that Lyme disease is not a common cause of idiopathic heart failure in the Midwestern United States and that false-positive Lyme disease serologic results are not rare among patients with severe heart failure. Patients with significant cardiac disease who are found to be EIA seropositive should have confirmatory Western blots performed before consideration of treatment. Based on our findings, we cannot recommend either the routine serologic screening of patients with idiopathic cardiomyopathy or aggressive (e.g., parenteral) antibiotic treatment of seropositive patients unless the specific clinical history suggests antecedent Lyme disease.

Abstract
LB is a multisystem illness caused by the spirochete B. burgdorferi. As with other spirochetal diseases, LB evolves in stages. Some manifestations are the result of persistent infection, whereas other symptoms are a consequence of immunologic changes secondary to the infection. Most disease manifestations are not specific to this illness. In addition, in endemic areas, almost 100% of the tick vector, the Ixodes species, are infected and the incidence rate of LB is as high as 1%. Because of these factors, the illness is overdiagnosed and overtreated. We have reviewed the current state of diagnosis and treatment of LB as well as questions that arise during the management of this illness.

Abstract
The skin diseases Erythema (chronicum) migrans (ECM, EM), Lymphadenosis benigna cutis (LABC), and Acrodermatitis chronica atrophicans (ACA) have long been described in northern Europe, and dermatologists are very familiar with these manifestations, which have been successfully treated with penicillin for about 40 years without the causative agent being known. Certain neurologic symptoms could be linked to tickbites during the 1920's and later also to EM. In 1977, Steere et al. reported a new form of inflammatory arthritis, mainly in school children in the community of Lyme, Connecticut, U.S.A., which they could also associate with preceding erythema and tickbites. Five years later, Burgdorfer was able to isolate Borrelia spirochetes from Ixodes ticks, which are known to be vectors of Lyme disease as well as of EM and ACA. The following year, Borrelia spirochetes were also isolated from Ixodes ticks and from skin lesions of patients in Sweden and Germany. These findings resulted in a large number of reports of new discoveries related to this infection, which is now known under the names of tick-borne or Lyme borreliosis and, in the U.S., also as Lyme disease or Lyme arthritis. It has proven to be a great imitator disease, mainly through its involvement of the neurological system, and to be far more widespread than previously thought. The full course of the disease is not yet known, however it is clinically, like another spirochetosis, syphilis, divided into early and late stages. Manifestations involve mainly the skin, the joints, the nervous system (Neuroborreliosis), and the heart. Antibiotic treatment is effective, especially in the early stages. Like syphilis, the disease can be self-healing without treatment. People who are exposed to ticks should be aware of the risk of contracting this disease, also in Japan where Ixodes ticks have been shown to be carriers of Borrelia spirochetes. Cases, particularly of EM, but also with neurological symptoms, have already been diagnosed in Hokkaido, Honshu, Shikoku, and Kyushu. As Lyme borreliosis is now proven to exist in Japan, it is beneficial for dermatologists to know about the various presentations of this disease. This paper will briefly summarize the historical background, the clinical stages, the diagnosis, and the treatment of Lyme borreliosis, with a summary of the present situation in Japan.

Abstract
Lyme disease is increasingly being reported throughout the United States and many parts of the world. Borrelia burgdorferi, the etiologic agent of Lyme disease, is a spirochete that, not unlike the treponema of syphilis, can cause a spectrum of disease from the initial skin lesion, through widely varied symptoms and signs, to chronic neurologic and arthritic disability. The borrelial spirochete and Lyme disease are the subject of this review. A subsequent article will review other definite and possible cutaneous manifestations of borreliosis.

Abstract
Cardiac manifestations are reported in 0.3%-4.0% of European patients with Borrelia burgdorferi (B.b.) infection. Usually symptoms disappear within 6 weeks. We report a case with persistent impairment of atrioventricular (AV) conduction. Diagnosis was confirmed by demonstration of IgM antibodies and increase of IgG antibody titers against B.b. in serum, by isolation of the spirochete from skin biopsy material and by the typical clinical combination of erythema migrans, Bannwarth syndrome (meningoradiculitis), and complete heart block. Despite immediate antibiotic therapy with ceftriaxone, first degree AV block and second degree block Wenckebach with atrial pacing at 100 beats/minute persisted for 2 years. We conclude, that Lyme carditis can cause long-standing or irreversible AV conduction defects despite adequate and early antimicrobial therapy.

Abstract
Four patients with Lyme borreliosis had atrioventricular conduction disturbances. All four were positive for specific antibodies against Borrelia burgdorferi measured by indirect immunofluorescence tests. Biopsy specimens, which were obtained in three patients, showed band-like infiltrates of plasma cells and lymphocytes in the endocardium. There was diffuse infiltration of the interstitium of the myocardium by lymphocytes, plasma cells, and macrophages. In two patients single fibre necrosis was seen in the myocardium. Biopsy specimens of the heart showed spirochetes in all three patients and serial sections stained by the Bosma-Steiner technique showed that they resembled Borrelia burgdorferi. At follow up one patient had persistent complete atrioventricular block, despite treatment with antibiotics and corticosteroid, and a permanent pacemaker was implanted.

Abstract
Craniomandibular disorders cause many pleomorphic and seemingly unrelated clinical manifestations that mimic other more serious medical problems and thus can present physicians and dentists with a challenge that invites misdiagnosis and improper treatment planning. Conversely, misdiagnosis and ineffective treatment planning are facilitated when serious medical problems manifest a range of signs and symptoms that are clinically similar to temporomandibular joint muscle dysfunction. At times, the patient's response to therapy may be the best method of corroborating a diagnosis, as illustrated in this report of a patient with Lyme disease that was misdiagnosed as a temporomandibular joint disorder. Lyme disease has already reached epidemic proportions in several parts of the United States and its geographic distribution is spreading. Because Lyme disease is a life-threatening illness whose clinical manifestations can mimic temporomandibular joint/myofascial pain-dysfunction, it is the responsibility of every dentist who treats craniomandibular disorders to become familiar with the clinical presentations of Lyme disease and more proficient in its differential diagnosis.

The pathogenesis of chronic manifestations in Lyme borreliosis, a disease induced by Borrelia burgdorferi, is at present unresolved. By testing monoclonal antibodies directed against various borrelia antigens, we found an antigenic determinant shared by the 41 kDa flagella protein and human tissue, especially prominent on myelinated fibers of human peripheral nerve, on nerve cells and axons of the central nervous system, as well as on certain epithelial cells (including joint synovia) and on heart muscle cells. Immune reactions against such a shared antigen could play a pathogenetic role in chronic organ manifestations of Lyme borreliosis.

Abstract
Lyme disease is caused by the spirochete Borrelia burgdorferi, which is carried by infected ticks. This disorder has a variable clinical course with multisystem manifestations, including dermatologic, neurologic, cardiac, and rheumatologic abnormalities. Although Lyme disease has been commonly associated with stages, the utility of staging may be limited due to the inconsistency of clinical manifestations among patients. Furthermore, stages may overlap as a result of the acute and chronic phases of the disease. The laboratory characteristics of Lyme disease are highly variable. The use of microbiologic cultures in establishing the diagnosis requires several weeks and has a low yield of positivity. Serologic assays using indirect immunofluorescence and enzyme-linked immunosorbence are preferred. Because of the highly variable features of Lyme disease, clinical and laboratory features must be correlated and interpreted in the context of the disease. Treatment should be initiated as early as possible after the onset of illness. Prompt therapeutic intervention may result in early resolution of the dermatologic hallmark, erythema chronicum migrans, as well as prevention and attenuation of subsequent complications.

Abstract
The usefulness of Western blot in the serological diagnosis of Lyme borreliosis was evaluated compared with an ELISA using a whole cell sonicate antigen. Fifty-three of 68 (78%) patients with neuroborreliosis had positive IgM and/or IgG immunoblots and 40 of 68 (59%) had positive IgM and/or IgG ELISA titers in serum. Eight of 44 (18%) controls with meningitis/encephalitis of non-borrelia etiology had positive IgM and/or IgG immunoblots and 4 of 44 (9%) had positive IgM and/or IgG ELISA titers in serum. Western blot was more sensitive than ELISA, the difference being most pronounced in sera from patients with neurological disease for four weeks or less. Both patients and controls lived in an area endemic for Lyme borreliosis and some ELISA negative but Western blot positive controls were thought to have been previously exposed to Borrelia burgdorferi. However, the specificity for current disease was not improved by Western blot. In conclusion, Western blot does not seem to be the method of choice for screening purposes in a routine laboratory but can be used as a complement to ELISA for serodiagnosis in patients with disease of short duration.

Abstract
Attempts were made to culture spirochetes from the cerebrospinal fluid of 105 patients with suspected Lyme borreliosis with neurological complications. At the final evaluation, only 38 patients fulfilled the criteria of neuroborreliosis. Spirochetes were cultured from the cerebrospinal fluid of four of these patients. All four had pleocytosis in their cerebrospinal fluid and a history of neurological symptoms of only four to ten days. Two had no detectable antibodies in their cerebrospinal fluid against any of the isolated spirochetes, neither when tested with an ELISA nor by Western blot. A distinctly stronger antibody reaction to the homologous isolate than to the heterologous isolates was found in serum and cerebrospinal fluid from one patient. The cells of the isolates were morphologically similar and showed a very similar protein pattern when analyzed by SDS-PAGE. Cells of all isolates reacted with the monoclonal antibodies H5332 and H9724, which also react with Borrelia burgdorferi isolate B31, the type species. One isolate lost a major protein of 23 kD after subcultivation for four months. We conclude that isolation of spirochetes from cerebrospinal fluid is not suitable as a routine method but might prove successful in clinically selected cases of Lyme borreliosis. The patient antibody response to spirochetal components was analyzed with Western blot. Antibodies to low-molecular components including a major protein with a molecular weight of 21-23 kD, and to a 41-kD major flagellar protein, were the first to appear in serum and in CSF samples. No single band in the immunoblots was found to be specific. By requiring a 41 kD band together with at least one low-molecular band for a positive immunoblot, 53 of 68 (78%) patients with neuroborreliosis had positive IgM and/or IgG serum immunoblots by visual reading of coded material. Western blot was more sensitive than ELISA based on a sonicate antigen which identified 40 of the 68 (59%) patient samples as positive, but not significantly more sensitive than ELISA based on a purified flagellum antigen which identified 50 of 68 (74%). Western blot tended to be more sensitive than the flagellum ELISA regarding sera from patients with neurological symptoms of 2 weeks or shorter duration. However, there was a tendency towards a lower specificity regarding the serological diagnosis of current Lyme borreliosis by Western blot than by sonicate and flagellum ELISAs.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The findings in a patient with complete AV block and intra-atrial conduction disturbances due to Lyme disease are presented. The electrocardiographic follow-up and serial EP findings suggest that complete AV block in Lyme disease may signify a more extensive affection of the AV conduction system (with eventually attendant intra-atrial conduction disturbances) than described in earlier reports. An almost complete resolution of the considerable damage to the conduction system occurred within two weeks.

Abstract
Lyme borreliosis (Lyme disease), a common tick-borne disorder of people and domestic animals in North America and Europe, is caused by the spirochete Borrelia burgdorferi. Following the discovery and initial propagation of this agent in 1981 came revelations that other tick-associated infectious disorders are but different forms of Lyme borreliosis. A challenge for the clinician and microbiology laboratory is confirmation that a skin rash, a chronic meningitis, an episode of myocarditis, or an arthritic joint is the consequence of B. burgdorferi infection. The diagnosis of Lyme borreliosis may be established by (i) directly observing the spirochete in host fluid or tissue, (ii) recovering the etiologic spirochete from the patient in culture medium or indirectly through inoculation of laboratory animals, or (iii) carrying out serologic tests with the patient's serum or cerebrospinal fluid. The last method, while lacking in discriminatory power, is the most efficacious diagnostic assay for most laboratories at present.

Abstract
Lyme disease has been recognized in humans since 1975 when it was associated with an outbreak of oligoarthritis in children in Lyme, Connecticut. Erythema chronicum migrans (ECM) is a clinical marker for the human disease, which usually appears within 3 to 32 days after an infected tick bite. Lyme disease is caused by spirochete, Borrelia burgdorferi, which is vectored by the hard ticks Ixodes dammini or Ixodes pacificus in the United States. In humans, Lyme disease has been found to cause a variety of clinical syndromes including cardiopathy, neuropathy, dermatopathy, and arthropathy. Human Lyme carditis is characterized by varying degrees of atrioventricular (AV) heart block that usually resolve regardless of therapy. Lyme disease has been reported in the dog as an arthropathy. This article reports a case of complete heart block and myocarditis in a dog with a positive titer for B burgdorferi, in which clinical and pathologic findings were similar to those seen in human Lyme myocarditis.
