Contegra (Medtronic, Minneapolis, MN) conduits are routinely used in cases of right ventricular outflow tract reconstruction during congenital heart surgery. We report two cases of Q fever endocarditis involving Contegra conduits. Surgical treatment and distinct aspects of both unusual cases are described.

Acute renal failure associated with rhabdomyolysis in acute Q Fever.

The clinical presentation of Q fever is polymorphic and non-specific, and it may be presented as an acute or chronic disease. Renal complications of acute Q fever such as acute glomerulonephritis are not uncommon. Acute renal failure induced by rhabdomyolysis in acute Q fever has until now never been reported in the literature. We presented a case of acute Q fever associated by extreme rhabdomyolysis and consecutive acute renal failure. A male patient was treated with doxycycline and continuous venovenous hemodiafiltration. After two weeks of treatment, the patient completely recovered kidney …

The value of follow-up after acute Q fever infection.

This is a case report of a 53-year-old woman involved in an outbreak of Q fever, in whom Q fever endocarditis was diagnosed 18 months after acute Q fever infection. At the time of diagnosis, she was completely asymptomatic and without screening for chronic Q fever, this severe potentially life-threatening infection would probably not have been recognised until significant valvular destruction had taken place. Early diagnosis enabled prompt, potentially curative medical treatment to start without the need for valvular heart surgery. The authors advocate that serological monitoring should be car…

Q fever: a new cause of 'doughnut' granulomatous lobular panniculitis.

Q fever is an uncommon zoonotic rickettsial disease with no exanthem or specific cutaneous lesions. Only nonspecific cutaneous involvement has been reported to date. A 69-year-old Spanish woman with chronic myelogenous leukaemia developed fever and two subcutaneous nodules. The patient complained of extreme pain. Biopsy revealed a granulomatous lobular panniculitis with a characteristic 'fibrin ring' or 'doughnut' appearance: fibrin and inflammatory cells arranged around a central clear space. Changes of membranous lipodystrophy were also found. Q fever serological studies were positive. Our p…

Significance of Q fever serologic diagnosis in clinically suspect patients.

Q fever is caused by C. burnetii, an intracellular obligate bacterium. For clinical confirmation of Q fever, diagnosis of interstitial pneumonia is of significance. The acute disease varies in severity from minor to fatal, with the possibility of serious complications. Chronic endocarditis is a well-known outcome. Symptoms of Q fever can vary; fixing diagnosis is done by serology with the phase I and the phase II antibody. We tested 44 sera of 31 clinically suspect patients. From these, 22 patients were taken to the infection clinic, 8 to the pulmonary clinic, and one to the general hospital. …

Q fever outbreak during the Czech Army deployment in Bosnia.

An epidemic of Q fever was identified among soldiers from the Czech Republic serving in the U.N. Stabilization Force in Bosnia and Herzogovina in 1997. There were 26 serologically confirmed infections, or 4.6% of those exposed. There were 14 cases of febrile illness and 12 subclinical infections. Prodromal symptoms of malaise, headache, backache, and fatigue were followed by fever > or = 39 degrees C with an intermittent course. Physical findings were unremarkable except in five cases with radiographically confirmed pneumonia. Cases were treated with doxycycline, trimethoprim-sulfamethoxazole,…

Q fever in New South Wales Department of Agriculture workers.

A cross-sectional survey of staff of the New South Wales Department of Agriculture for prior exposure to Q fever was conducted using the complement fixation test, indirect immunofluorescent antibody test, a delayed hypersensitivity skin test, a standard questionnaire, and a supplemental history, with the aim being to determine the proportion of employees that have been in contact with Q fever and the jobs that pose the greatest risk of exposure to the disease. Of 829 employees, 89 (10.7%) tested positive, with those handling livestock being more likely to have been exposed to Q fever than empl…

Acute Q fever pneumonia: a review of 80 hospitalized patients.

STUDY OBJECTIVES: To emphasize epidemiologic, clinical, or radiologic characteristics whose detection could lead to an early diagnosis and to enhance therapeutic efficacy. PATIENTS: Eighty hospitalized patients from 1982 to 1996. DESIGN: The diagnosis of Q fever infection was serologically confirmed in all the patients (phase II Coxiella burnetii antibody) using the complement fixation test and/or the indirect immunofluorescence antibody test. RESULTS: Patients from rural and urban areas were noted in the same proportion; however, the usual epidemiologic factors such as contact with cats or…

Necrotizing bronchitis, angiitis, and amyloidosis associated with chronic Q fever.

The authors report the clinical, radiological and histological findings in a 63-year-old male patient who developed severe necrotizing bronc … defense system. The clinical history, histological and immunological findings suggest that chronic Q fever may induce remarkable changes in the immune system, comparable to autoimmune-reactive diseases.

[Q-fever associated myocarditis in a 14-year-old boy].

A 14-year-old boy presented with the symptoms and clinical signs of myocarditis. Ventricular arrhythmias were the main manifestation. Dilate … tion of left ventricular dimensions and structure over the following months. Cardiac involvement in Q fever is rare, and with it endocarditis is usually seen as a chronic form of the disease. Myocarditis associated with Q fever has been reported only in some rare cases but not in children. The case reported here illustrates that the diagnosis of Q fever s …

Latent Q fever in cattle in southern Moravia (Czech Republic).

In 1991-92, a complement fixation test technique (titre > or = 8) was used in serological assays of antibodies to Coxiella burnetti performe … rm, reproduction characteristics of cows were monitored to ascertain possible links with the latent Q fever infection, but no relationship was found in this case. In 1991, sera of 56 employees from farms with seropositive cattle (in H. V. and P. and from another farm) and 26 employees from an industrial company were tested but the complement fixation test …

Temporal arteritis associated with acute Q fever. A case report.

The authors describe the case of a sixty-four-year-old man who presented with clinical and histopathologic evidence of temporal arteritis associated with acute Q fever. This association, which has not been previously reported, supports the possible infectious etiology in temporal arteritis.

Serological differentiation between acute (late control) and endocarditis Q fever.

AIMS: To differentiate the serological profiles of chronic (endocarditis) Q fever from the late follow up of acute cases. METHODS: Twenty patients (10 diagnosed with acute and 10 with endocarditis Q fever) were studied. Those diagnosed with acute infection were followed up from 2.5 to 88 months (mean 35.8 months). Serological variables included indirect immunofluorescence against phase I and II of Coxiella burnetii (IgM, IgG, and IgA), complement fixation and rheumatoid factor (RF). RESULTS: All patients with titres of IgA against phase I, after IgG removal, equal to or above 320 and a compl…

Q fever endocarditis: diagnostic approaches and monitoring of therapeutic effects.

The scope of current diagnostic methods for Q fever endocarditis includes serology, direct demonstration of Coxiella burnetii in the resected heart valve tissue, and animal inoculation studies. Illustrated by a clinical case report, the different methods are presented and discussed. Serology represents the primary method, using the techniques of complement fixation, indirect immunofluorescence, and enzyme-linked immunosorbent assay (ELISA). The latter two techniques allow the detection of immunoglobulins G, M, and A to the phase I and II antigens of C. burnetii. After cardiac surgery, we visua…
