Q fever is a common zoonosis with almost a worldwide distribution caused by Coxiella burnetii. Farm animals and pets are the main reservoirs of infection and transmission to humans is usually via inhalation of contaminated aerosols. Infection in humans is often asymptomatic, but it can manifest as an acute disease (usually a self-limited flu-like illness, pneumonia or hepatitis) or as a chronic form (mainly endocarditis, but also hepatitis and chronic-fatigue syndrome). In Tunisia, although prevalence of anti-Coxiella burnetii was high among blood donors, Q fever was rarely reported and frequently miss diagnosed by physicians. This study is a review of epidemiological and clinical particularities of Q fever in Tunisia.

We present three cases of septic pulmonary embolism which occurred as a result of three different causes. The first case, was a 23 year old woman suffering from cough, sputum, hemopthisis and pleuritic chest pain. She had a right subclavian port. On her thorax computed tomography (CT) scans there were widespread bilateral, irregular parenchymal nodular infiltrates and some of them beginning to cavitate. Meticilin resistant stafilococus aureus (MRSA) was isolated from the blood culture and septic embolism was diagnosed. A month after antibiotic theraphy her parenchymal nodules have considerably decreased in size. The second case was a 40 year old woman admitted to our hospital with the same complaints. Her radiological findings were similar. Meticilin sensitive stafilococus aureus (MSSA) was isolated from the blood cultures and antibiotic theraphy was initiated. To investigate the etiology of the nodules due to septic embolism, echocardiography was performed and infective endocarditis was diagnosed. After the antibiotic theraphy and a tricuspid valve operation her parenchymal nodules disappeared. The final case involved a 51 year old man suffering from fever, fatigue, cough and pain in the left arm for one week. His general status was bad. His radiological findings were also similar to the others. Staphillococcus aureus was isolated from blood and wound culture. Following clinical and radiological findings we thought it was a case of septic pulmonary embolism and antibiotic theraphy was started. Despite the therapy we did not take fever response and he died five days after antibiotic therapy. In conclusion, septic pulmonary embolism should be considered in bilateral cavitary nodular infiltrates and must be managed fast.

Early diagnosis of brucella endocarditis is of paramount importance because of its fatal consequences. The most commonly affected localization is the aortic valve, while mitral valve involvement is rare. A 44-year-old male patient with a history of rheumatic heart disease presented with fever, fatigue, and back pain. Three consecutive blood cultures revealed growth of Brucella melitensis. On transthoracic echocardiography, mitral valve area was 1.5 cm2 and there was mild mitral regurgitation. Transesophageal echocardiography showed multiple vegetations on the anterior and posterior mitral valve leaflets. Combination of medical and surgical treatment was planned for the patient with the diagnosis of brucella endocarditis.

A 52-year-old diabetic male was admitted due to 1-month history of fever, fatigue, and mild shortness of breath. Three months prior to admission, he had undergone aortic valve replacement, with a prosthetic one, because of streptococcus viridans endocarditis complicated by severe aortic regurgitation. Transesophageal echocardiogram revealed prosthetic valve endocarditis with dehiscence of the aortic valve and an abscess cavity extending from the aortic root into the ascending aorta. Blood cultures and serology were negative. Due to clinical deterioration, despite antibiotic therapy, the patient was reoperated on and the aortic valve and ascending aorta were replaced with a homograft. Valve culture grew Aspergillus flavus. This case is an example of a rare but of increasing frequency complication after cardiac surgery. Considering the high mortality from this complication, early recognition is of paramount importance.

Brucellosis which is a endemic in Turkey, is a systemic infection which can affect any organ or system in the body. Since signs and symptoms of brucellosis resemble many other diseases, misdiagnosis and related increase in morbidity rate, are common. In this report, a case of brucellosis complicated with endocarditis, pyelonephritis, sacroileitis and thyroiditis, was presented. The case was a 32-years-old female patient in whom the diagnosis of brucellosis was delayed by 12 months since it was not taken into consideration during the clinical follow-up of the patient in various clinical centers. The patient was admitted to our center with the complaints of fever, headache, back pain, night sweats, fatigue, loss of appetite, weight loss, dysuria and polyuria. The patient had a history of consumption of raw milk and dairy products. Positive Brucella tube agglutination test (1/1280) and isolation of Brucella spp. in blood cultures led to the diagnosis of brucellosis. Sacroileitis was diagnosed upon pain on right hip joint movements, pain and restriction at the same joint in FABER test. The detection of vegetation during echocardiography, cardiac murmur during physical examination and the determination of increased ESR and CRP levels led to the diagnosis of endocarditis. Abdominal ultrasonography and urinalysis results (hematuria, proteinuria and pyuria) revealed pyelonephritis and increased free T3 and T4, decreased TSH and positive anti-thyroid autoantibodies (anti-TG, anti-TPO) revealed thyroiditis. Treatment was started with combination of rifampisin (1 x 600 mg/day) and doxycycline (2 x 100 mg/day). After the diagnosis of endocarditis, trimethoprim-sulfamethoxazole (3 x 960 mg/day) and streptomycin (1 x 1 g/day) were added to the treatment. Valve replacement surgery was planned, however, the patient didn't accept surgical intervention and antimicrobial treatment continued with streptomycin for 21 days and other antibiotics for six months. The patient exhibited significant improvement after the medical treatment. Although sacroileitis is a frequent complication of brucellosis, endocarditis, thyroiditis and pyelonephritis are among the rare complications. In cases of brucellosis with multiorgan involvement including endocarditis, successful results may be achieved by aggressive antimicrobial treatment. In endemic areas, brucellosis should always be taken into consideration in patients with fever of unknown origin and multisystem involvement.

A 77-year-old man complained general fatigue and fever. Preoperative echocardiography revealed vegetation of aortic valve, abnormal shunt flow from the sinus of Valsalva was detected in the right atrium and ventricle without perivalvular abscess cavity or aneurysm of the sinus of Valsalva. He diagnosed aortic valve endocarditis with aorto-right atrium and ventricle fistula. He received aortic valve replacement and patch closure at the sinus of Valsalva using the pericardium. Residural aortic-right atrium and ventricle shunt was not detected after the operation, the post operative course was uneventful without congestive heart failure nor signs of infection.

Patent arterial duct (PAD) is a congenital heart abnormality defined as persistent patency in term infants older than three months. Isolated PAD is found in around 1 in 2000 full term infants. A higher prevalence is found in preterm infants, especially those with low birth weight. The female to male ratio is 2:1. Most patients are asymptomatic when the duct is small. With a moderate-to-large duct, a characteristic continuous heart murmur (loudest in the left upper chest or infraclavicular area) is typical. The precordium may be hyperactive and peripheral pulses are bounding with a wide pulse pressure. Tachycardia, exertional dyspnoea, laboured breathing, fatigue or poor growth are common. Large shunts may lead to failure to thrive, recurrent infection of the upper respiratory tract and congestive heart failure. In the majority of cases of PAD there is no identifiable cause. Persistence of the duct is associated with chromosomal aberrations, asphyxia at birth, birth at high altitude and congenital rubella. Occasional cases are associated with specific genetic defects (trisomy 21 and 18, and the Rubinstein-Taybi and CHARGE syndromes). Familial occurrence of PAD is uncommon and the usual mechanism of inheritance is considered to be polygenic with a recurrence risk of 3%. Rare families with isolated PAD have been described in which the mode of inheritance appears to be dominant or recessive. Familial incidence of PAD has also been linked to Char syndrome, familial thoracic aortic aneurysm/dissection associated with patent arterial duct, and familial patent arterial duct and bicuspid aortic valve associated with hand abnormalities. Diagnosis is based on clinical examination and confirmed with transthoracic echocardiography. Assessment of ductal blood flow can be made using colour flow mapping and pulsed wave Doppler. Antenatal diagnosis is not possible, as PAD is a normal structure during antenatal life. Conditions with signs and symptoms of pulmonary overcirculation secondary to a left-to-right shunt must be excluded. Coronary, systemic and pulmonary arteriovenous fistula, peripheral pulmonary stenosis and ventricular septal defect with aortic regurgitation and collateral vessels must be differentiated from PAD on echocardiogram. In preterm infants with symptomatic heart failure secondary to PAD, treatment may be achieved by surgical ligation or with medical therapy blocking prostaglandin synthesis (indomethacin or ibuprofen). Transcatheter closure of the duct is usually indicated in older children. PAD in preterm and low birth weight infants is associated with significant co-morbidity and mortality due to haemodynamic instability. Asymptomatic patients with a small duct have a normal vital prognosis but have a lifetime risk of endocarditis. Patients with moderate-to-large ducts with significant haemodynamic alterations may develop irreversible changes to pulmonary vascularity and pulmonary hypertension.

Streptococcus suis, a major global porcine pathogen, is an emerging zoonosis in Southeast Asia that triggered a 2005 outbreak in China. S. suis causes meningitis, sepsis, and endocarditis in both pigs and humans and involves significant mortality. We report the case of a previously healthy 50-year-old dairy farmer who developed S. suis type 2 endocarditis complicated by pulmonary embolism and spondylitis. He experienced a high fever, chills, fatigue, and worsening low back pain in the 6 weeks prior to admission. On physical examination, he had lumbar spine tenderness and weakness of the left leg. Blood culture identified penicillin-sensitive S. suis type 2. Echocardiography showed vegetation on the tricuspid valve, and magnetic resonance imaging (MRI) showed signs of spondylitis. The man reported sudden chest pain several days after admission, which computed tomography (CT) showed what was diagnosed as a septic pulmonary embolism. He was treated with penicillin G for 4 weeks and gentamicin for the first 2 weeks, followed by 2 weeks of oral amoxicillin, after which his symptoms gradually improved. The infection source was probably his dairy herd, since calves often bit his fingers while feeding and S. suis was found in their oral mucus. Over 400 cases of human S. suis infection have been reported globally, but this is, to our knowledge, the first known case of bovine transmission. All of Japan's 8 other cases involved occupational swine exposure, 5 of whom had injuries to their fingers. This emerging situation should be made known to all possibly involved in unprotected direct contact with swine and cattle, particularly when the skin could be compromised by cuts or abrasions.

The authors report the occurrence of infective endocarditis in a 32-year-old man with a ventricular septal defect and a left ventricular-to-right-atrial shunt who adhered to the revised 2007 American Heart Association guidelines for infective endocarditis. The patient had received antibiotic prophylaxis prior to multiple previous dental procedures. At a recent dental evaluation for fillings, he was informed that he no longer needed prophylaxis. Fatigue and fevers developed 1 week later, and he was treated with an oral course of ciprofloxacin. The symptoms recurred, and blood cultures grew Streptococcus viridans. A 7-mm vegetative mass was seen on the septal leaflet of the tricuspid valve during transesophageal echocardiography. This report raises the concern that patients with ventricular septal defects and left ventricular-to-right-atrial shunts are at higher risk for endocarditis and may require antibiotic prophylaxis.

A 71-year-old man presented with general fatigue associated with syncope and fever, and was admitted to our hospital and treated with antibiotics for pneumonia. On day 10 after admission, cardiac echocardiography showed a ventricular septal perforation and giant vegetation floating in the right ventricle near the tricuspid valve, which had not been detected at the time of admission. An emergency operation (including vegetation excision, debridement, ventricular septal perforation patch closure, and tricuspid valve replacement) was performed. A permanent pacemaker was implanted on postoperative day 34, and the patient was discharged without any complications. A culture of the excised vegetation and blood culture revealed methicillin-susceptible Staphylococcus aureus. There has been no previous report of a presenting ventricular septal perforation caused by right-sided infective endocarditis.
