Lyme disease typically begins with a unique skin lesion, erythema chronicum migrans (ECM) (stage 1). Patients with this lesion may also have headache, meningeal irritation, mild encephalopathy, multiple annular secondary lesions, malar or urticarial rash, generalized lymphadenopathy and splenomegaly, migratory musculoskeletal pain, hepatitis, sore throat, non-productive cough, conjunctivitis, periorbital edema, or testicular swelling. After a few weeks to months (stage 2), about 15% of patients develop frank neurologic abnormalities, including meningitis, encephalitis, cranial neuritis (including bilateral facial palsy), motor or sensory radiculoneuritis, mononeuritis multiplex, or myelitis. At this time, about 8% of patients develop cardiac involvement--AV block, acute myopericarditis, cardiomegaly, or pancarditis. Throughout this stage, many patients continue to experience migratory musculoskeletal pain in joints, tendons, bursae, muscle, or bone. Months to years after disease onset (stage 3), about 60% of patients develop frank arthritis, which may be intermittent or chronic. Recently evidence suggests that Lyme disease may also be associated with chronic neurologic or skin involvement. Thus, Lyme disease occurs in stages with different clinical manifestations at each stage, but the course of the illness in each patient is highly variable.

The clinical findings during a major epidemic of Q-fever which affected 415 people in the Val de Bagnes (Valais, Switzerland) in the autumn of 1983 are reported. Q-fever symptoms were evident in 191 cases but inconspicuous or absent in 224 cases. The symptoms most frequently reported were prolonged high fever, headaches, severe exhaustion, loss of appetite, cough and myalgia. Amongst disorders which accompany acute Q-fever, pneumonia and granulomatous hepatitis are very frequent, while myopericarditis and glomerulonephritis are less frequently observed. Endocarditis, a later complication of Q-fever, is a severe illness which more frequently affects patients with underlying valvular lesions. New serological techniques now permit more rapid and more accurate diagnosis of both acute and chronic Q-fever.

The article presents epidemiological, clinical, laboratory and therapeutic characteristics of Brill-Zinsser disease (BZD). A total of 25 cases of BZD were retrospectively analyzed during the period from January 1, 1980 through December 31, 2000, and etiology was confirmed by rickettsial complement-fixation test (CFT). The majority of cases 15 (60%) quoted history of primary attack of epidemic typhus during or after the World War II. During the course of the disease in our patients different organic systems were involved. Aseptic meningitis was verified in 21 (84%) patients, rash in 17 (68%), liver lesion in 14 (56%), pneumonitis in 7 (28%), myopericarditis in 7 (28%) and 5 (20%) had renal lesion. Not a single clinical symptom or finding of disease has a diagnostic particularity. However, long term fever, headache, rash and aseptic meningitis, or information of infestation with lice in childhood, or a history of epidemic typhus should arouse a suspicion of this disease, which still occurs in Croatia.

Novel influenza A (H1N1) has created a major worldwide health problem within a short time after its emergence. This infection is often self-limited, but sometimes can cause severe and fatal complications. In this study, we present two rare complications of pandemic influenza A, who were referred to Razi University Affiliated Hospital in northern Iran. The first case was a 30-year-old man with severe headache and high fever accompanied with chills, generalized myalgia, and arthralgia. Cerebrospinal fluid analysis was consistent with aseptic meningitis. The second case, a 25-year-old pregnant woman with high fever, chills and severe fatigue and malaise, developed tachypnea, tachycardia, respiratory distress, cyanosis and loss of consciousness a few hours after admission. Echocardiography reported myopericarditis. The patient was transferred to the intensive care unit and mechanical ventilation was begun. The next day, the patient started vaginal bleeding which progressed to spontaneous abortion three days later. Diagnosis of novel influenza A (H1N1) was confirmed using real-time reverse-transcriptase PCR of a pharyngeal swab.

We present a case of a 48-year-old male who presented with worsening pleuritic chest pain for 2 h. He also complained of fever, malaise, headache and severe neck pain. Electrocardiogram (ECG) showed ST segment elevation in leads I, II, aVL and V5 with PR elevation and ST depression in aVR. On admission, troponin-I was 14.8 ng/mL. Based on ECG changes, elevated troponin and family history of early coronary artery disease, the patient was emergently taken to cardiac catheterization lab. Angiography showed non-obstructive coronaries, mild hypokinesis of mid inferior and anterolateral wall with ejection fraction (EF) of 40-45%. Based on above presentation and angiography findings, the diagnosis of acute myopericarditis was made. He was started on colchicine and ibuprofen. The other workup to determine etiology of myopericarditis was negative as shown below. Given the history of fever, headache and worsening neck pain, we also became suspicious of meningitis. Lumbar puncture was performed which was negative. On the day of admission, he was found to have blasts on complete blood count and peripheral smear. Bone marrow biopsy and flow cytometry confirmed the diagnosis of acute myeloid leukemia (AML). He received induction and salvage therapy. Repeat bone marrow confirmed complete remission and normal cytogenetics. Although pericardial or myocardial biopsies are unavailable for our patient, in the absence of other causes, it does appear that his acute myopericarditis was associated with AML.

BACKGROUND Influenza viruses induce uncomplicated infections in most cases in individuals with no known predisposing factors. Acute febrile illness is generally limited to upper respiratory symptoms and several constitutional symptoms, including headache, lethargy, and myalgia. However, influenza A virus is a cause of severe morbidity and mortality worldwide. Some patients are at risk for serious and fatal complications. Cardiac involvement is a well-known condition, but, clinically apparent influenza myocarditis is not common. Few reports exist regarding recurrent fulminant influenza myocarditis. CASE REPORT We report here a fatal case of heart failure following myocarditis in a 14-year-old female who had seasonal flu symptoms but was otherwise healthy. H3N2 influenza virus infection was detected by molecular analyses of throat and nasal swabs, suggesting damage to myocardial cells caused directly by the virus. CONCLUSIONS Pericardial effusion myopericarditis may occur during influenza virus infection in young individuals, even those with no known predisposing factors. Physicians need to be aware that acute myopericarditis can be a fatal complication of recent influenza virus infection in all patients with instable hemodynamics. Early diagnosis and treatment could reduce, in some cases, the risk of severe cardiac events. However, this sudden and fatal outcome was difficult to predict in a healthy young female with no known risk factors.

Mesalamine has been successfully used as a maintenance treatment in inflammatory bowel diseases such as ulcerative colitis and Crohn's disease for years. Most frequent adverse reactions to this medication are gastrointestinal disorders and headaches while cardiovascular complications are rare and poorly understood. We present a case of a 26-year-old male with ulcerative colitis developing myopericarditis on mesalamine therapy. Although cardiac involvement is reported to be an extraintestinal manifestation of the bowel disease, we describe evidence confirming the diagnosis of mesalamine-induced myopericarditis in our patient and discuss other reports on this topic. Even though myopericarditis is an uncommon adverse reaction to mesalamine, it should be considered in patients with chest pain during mesalamine therapy. In such cases, drug withdrawal may result in rapid clinical improvement. <Learning objective: Mesalamine therapy of inflammatory bowel disease (IBD) can be connected with common adverse reactions such as headaches and gastrointestinal problems. Cardiovascular complications in patients with IBD may be associated with the disease but may also occur due to mesalamine therapy. Drug cessation is then sufficient to achieve clinical improvement.>.

Dengue hemorrhagic fever is one of the most commonly encountered mosquito-borne viral infections of humans worldwide with multiple reported outbreaks. Cardiac involvement is a known manifestation of the disease usually presenting as rhythm abnormalities, myocarditis, or pericardial effusion, which may be clinically asymptomatic. We describe a case of a 30-year-old woman who presented to us with high-grade fever, headache, retro-orbital pain, generalized maculopapular rash with bilateral pleural effusion, and hypotension. Dengue non-structural protein 1 (NS1) antigen and IgM antibodies were positive on admission, supporting a diagnosis of dengue hemorrhagic fever. Cardiac troponin-I was elevated on admission (65 ng/L) with diffuse convex ST segment elevations on electrocardiogram, suggestive of possible myopericarditis. Echocardiogram on admission revealed minimal pericardial effusion with preserved ejection fraction. Despite administration of fluids and inotrope use, the patient's hypotension progressively deteriorated over the next 6 hours, associated with decreased urine output and worsening sensorium. Clinical examination revealed muffled heart sounds and raised jugular venous pressure. A repeat echocardiogram confirmed an increase in the pericardial effusion manifesting as cardiac tamponade. Ultrasound-guided pigtail catheter insertion led to a prompt removal of the excessive pericardial fluid and correction of hypotension. Early identification of this uncommon but important complication of dengue hemorrhagic fever led to a good outcome in our case.
