Lyme disease is caused by the spirochete Borrelia burgdorferi and is transmitted to humans by the bite of infected blacklegged ticks (Ixodes spp.). Early manifestations of infection include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. Left untreated, late manifestations involving the joints, heart, and nervous system can occur. A Healthy People 2010 objective (14-8) is to reduce the annual incidence of Lyme disease to 9.7 new cases per 100,000 population in 10 reference states where the disease is endemic (Connecticut, Delaware, Maryland, Massachusetts, Minnesota, New Jersey, New York, Pennsylvania, Rhode Island, and Wisconsin). This report summarizes surveillance data for 64,382 Lyme disease cases reported to CDC during 2003-2005, of which 59,770 cases (93%) were reported from the 10 reference states. The average annual rate in these 10 reference states for the 3-year period (29.2 cases per 100,000 population) was approximately three times the Healthy People 2010 target. Persons living in Lyme disease--endemic areas can take steps to reduce their risk for infection, including daily self-examination for ticks, selective use of acaricides and tick repellents, use of landscaping practices that reduce tick populations in yards and play areas, and avoidance of tick-infested areas.

A 22-year-old otherwise healthy woman presented to the Vanderbilt University Dermatology Clinics with a 5-year history of painful, red plaques and nodules on her shins and tops of her feet. She had initially been seen by a rheumatologist, who diagnosed her with erythema nodosum (EN) and prescribed oral prednisone. After 1 month of therapy, the condition had not improved and she discontinued the treatment. She had undertaken no additional therapy in the interim. At the onset of her condition, she was taking no medications, using only etonogestrel/ethinyl estradiol vaginal ring for contraception. Her condition did not change after beginning this hormonal contraception. Her lesions were constant, with variable waxing and waning and without any discernible precipitants. They were tender to palpation but were otherwise without symptoms. She denied any history of fever, joint pain, fatigue, cough, gastrointestinal symptoms, malaise, mucosal ulcerations, foreign travel, infectious exposures, or illicit drug use. Clinically, her anterior legs displayed moderately well demarcated patches and nodules with dusky erythema. The lesions were tender to palpation but were not present on the feet or above the knees. Darkened, bruise-like areas were also appreciated and corresponded to older, quiescent lesions. Results from a chest x-ray, complete blood cell count, and metabolic panel were normal. She declined a biopsy. She was treated with supersaturated solution of potassium iodide, indomethacin, methotrexate, and dapsone, all without benefit. She was then begun on etanercept 25 mg administered subcutaneously twice weekly. After 1 month she noticed the lesions beginning to fade with a concomitant decrease in their discomfort, and by 4 months she was clear of her disease. Results of all monitoring blood work were normal. At 6 months, her disease had resolved and her etanercept dose was reduced by half without any flare of her condition. She has continued 25 mg weekly for 12 months without developing any new lesions.

Lyme disease or Lyme borreliosis is the most common tick-transmitted disease in the Northern hemisphere and is caused by Borrelia burgdorferi spirochetes. Lyme disease commonly begins with a characteristic skin lesion, erythema migrans. Weeks or months later, the patients may have neurologic, joint, or cardiac abnormalities. Some patients may still present persistent deep fatigue and various unspecific symptoms after standard courses of antibiotic treatment for Lyme disease. This constellation of symptoms has been variously referred to as "chronic Lyme disease", or "post-Lyme disease syndrome". The first French National Consensus Conference on Lyme Disease was the reason to review all aspects of articular and cardiac manifestations of Lyme disease after a synthesis of recent literature. The involvement of Borrelia species in chronic Lyme disease and other pathologies is discussed.

This paper proposed a support vector machine (SVM) based classification method to identify diversified pathological voices. Sound signals were sampled from the pronunciation of a vowel "a" vocalized by 214 subjects, including 181 patients suffered from various dysphonias (such as polypoid degeneration, adductor spasmodic dysphonia, vocal fatigue, vocal tremor, vocal fold edema, hyperfunction, and erythema), and 33 healthy subjects. 25 acoustic parameters were calculated from the sampled data for each subject. The original acoustic dataset was first transformed via principal component analysis (PCA) method into a new feature space. To learn the identification boundary for healthy and pathological voices, a soft-margin SVM and three kinds of kernels were examined. The results under different combination of parameters and kernels were investigated. The effectiveness of SVM-based approach seems to be promising in the application of pathological voice identification.

An 88-year-old man from the Dominican Republic with a history of gastric adenocarcinoma was admitted with one month of fatigue, anorexia, weight loss, and abdominal pain. The dermatology department was consulted to evaluate an asymptomatic, shiny, firm, red nodule on the lower left chest, with an expanding rim of erythema. Skin biopsies were performed from the nodule and surrounding rim of erythema, which were both diagnostic of peripheral T-cell lymphoma (PTCL). This case is a unique example of PTCL with erysipelaslike spread.

We report a patient with acute heart failure due to human parvovirus B19 infection. The patient was a 36-year-old man with polyarthralgia, fatigue and swelling of his upper eyelids and all four limbs. These symptoms disappeared, but 5 days after the first consultation, the patient presented with severe exertional dyspnoea, chest pain and swelling of his whole body. Erythema was observed on the skin of hands, fingers and abdomen. Pleural and pericardial effusion, ascites and hepatosplenomegaly were detected. Laboratory examination showed positive results for anti-human parvovirus B19 IgM and B19 DNA in the serum. A diagnosis of acute heart failure by pericarditis caused by B19 was made. This case report suggests that B19 should be considered as a cause of acute heart failure through acute pericarditis.

A 77-year-old woman who have no past history, was admitted in a local hospital in Muroto City, Kochi, Japan, after several days of fever and severe general fatigue and generalized skin erythema. She was suspected to have Japanease spotted fever, which was a local pandemic disease. She was treated with minocycline immediately. The next day, she had consciousness disturbance and low blood pressure. Laboratory findings indicated disseminated intravascular coagulation (DIC) and multiple organ failure. She was referred to our hospital. An eschar was identified in the back of It. femur. Treatment included minocycline, ciprofloxain, gabexate mesilate, methylprednisolone, hemodialysis and mechanical ventilation. In spite of the avobe treatment, she died 3 days after admission of the local hospital. Though the serological test showed no positive antibody titer against Rickettsia japonica, Rickettsia japonica was isoleted from blood culture, to confirm Japanese spotted fever, Japanese spotted fever is generaly a curative disease with early diagnosis and minocycline. In this case, the patient died 3 days after proper diagnosis and treatment was started. We reported the second fatal Japanese spotted fever case in Japan.

Lyme disease is the most common tick-borne disease in the United States. This review details the risk factors, clinical presentation, treatment, and prophylaxis for the disease. Information was obtained from a search of the PubMed and MEDLINE databases (keyword: Lyme disease) for articles published from August 31, 1997, through September 1, 2007. Approximately 20,000 cases of Lyme disease are reported annually. Residents of the coastal Northeast, northwest California, and the Great Lakes region are at highest risk. Children and those spending extended time outdoors in wooded areas are also at increased risk. The disease is transmitted to humans through the bite of the Ixodes tick (Ixodes scapularis and Ixodes pacificus). Typically, the tick must feed for at least 36 hours for transmission of the causative bacterium, Borrelia burgdorferi, to occur. Each of the 3 stages of the disease is associated with specific clinical features: early localized infection, with erythema migrans, fever, malaise, fatigue, headache, myalgias, and arthralgias; early disseminated infection (occurring days to weeks later), with neurologic, musculoskeletal, or cardiovascular symptoms and multiple erythema migrans lesions; and late disseminated infection, with intermittent swelling and pain of 1 or more joints (especially knees). Neurologic manifestations (neuropathy or encephalopathy) may occur. Diagnosis is usually made clinically. Treatment is accomplished with doxycycline or amoxicillin; cefuroxime axetil or erythromycin can be used as an alternative. Late or severe disease requires intravenous ceftriaxone or penicillin G. Single-dose doxycycline (200 mg orally) can be used as prophylaxis in selected patients. Preventive measures should be emphasized to patients to help reduce risk.

We report a case of acute neck cellulitis and mediastinitis complicating a continuous interscalene brachial plexus block. A 61-yr-old man was scheduled for an elective arthroscopic right shoulder rotator cuff repair. A continuous interscalene block was done preoperatively and 20 mL of 0.5% bupivacaine and 20 mL of 2% mepivacaine were injected through the catheter. Postoperative analgesia was provided by a continuous infusion of bupivacaine, 0.25% at 5 mL/h for 39 h using a 240-mL elastomeric disposable pump. The day after surgery, the patient complained of neck pain. The analgesic block was not fully effective. He was discharged home. Three days later, the patient was readmitted with neck edema and erythema, fever and fatigue. Neck ultrasonography and computed tomographic scan revealed an abscess of the interscalene and sternocleidomastiod muscles and cellulitis, as well as acute mediastinitis. Two blood cultures and surgical samples were positive for Staphylococcus aureus. The infection was treated with surgery, the site was surgically debrided, and a 2-mo course of vancomycin, imipenem, and oxacilline. The technique of drawing local anesthetic from the bottle and filling the elastomeric pump was the most likely cause of infection. This case emphasizes the importance of strict aseptic conditions during puncture, catheter insertion, and management of the local anesthetic infusate.

Some overlap between features of fibromyalgia and systemic lupus erythematous (SLE) is well-recognized. Our objective is to describe eight patients with an original diagnosis of SLE, in whom, after re-evaluation, the multi-system symptoms could be explained on the basis of the dysautonomia that occurs in fibromyalgia.Seven of the eight patients were females. Their mean age was 31 years. All of them fulfilled the American College of Rheumatology criteria for fibromyalgia. Their lupus-like features that could later be explained by dysautonomia were the following: diffuse arthralgias with subjective feeling of swelling, malar erythema, syncopal episodes, profound fatigue, and distal vasospastic changes. Six patients had low titer ANA. None of the patients had signs of organic damage. Autonomic dysfunction was demonstrated by means of circadian studies of heart rate variability (6 patients) and/or tilt table testing (3 patients). We conclude that autonomic dysfunction may be an explanation for the lupus-like symptoms present in some patients with FM.
