Staphylococcal species, usually Staphylococcus aureus or Staphylococcus epidermidis, account for 70% to 95% of pacemaker and cardiac defibrillator infections. Infection limited to the generator pocket may cause pain, redness and swelling that is often accompanied by drainage or fistula formation. In this instance, the generator should be removed and reimplanted at another site as cure is rare with antimicrobial therapy alone. Infection of the leads usually tracks along the wire to include the endocardial surface and may involve the tricuspid valve and pocket. Clinical manifestations vary from mild chronic non-specific symptoms to septic shock with marked localizing signs. Septic embolization to the lungs is common and may cause cough, chest pain and shortness of breath that may be misdiagnosed. Blood culture and trans-oesophageal echocardiography (TOE) are the most important investigations.TOE has a sensitivity of >90%. Lead infection without vegetations may occur and these infections should be treated as for endocarditis. Antimicrobial therapy is an important part of treatment but lead infections are unlikely to cured unless the device is removed. Vancomycin is suitable as initial antimicrobial therapy as this covers both S. aureus and coagulase-negative staphylococci. Flucloxacillin, dicloxacillin or a first-generation cephalosporin are preferred if the organism is sensitive. The addition of low-dose gentamicin may improve bacterial killing. The duration of antimicrobial therapy and timing of replacement of the device have not been determined but 2 weeks treatment before removal and 2-4 weeks treatment after replacement is commonly administered.

This care study, using the Roper, Logan and Tierney Model of Nursing, examines the presentation of a patient with a history of drug misuse and a current diagnosis of infective endocarditis and hepatitis C. While this particular model of nursing incorporates 12 activities of daily living, this care study will deal with three specific activities: maintaining a safe environment, communication and breathing. One of the main concerns arising from this care study was the inadequate management of pain for the patient. It is suggested in the literature that healthcare professionals do not always adequately address pain management, primarily because of fear of causing addiction. The authors suggest that the patient's history of drug misuse in this study may have further mitigated against him receiving adequate pain control.

The genus Ruminococcus which are anaerobe Gram positive cocci, previously classified as Peptostreptococcus, may colonize the upper respiratory tract, gastrointestinal tract, vagina and skin of humans and animals. In this report a case of liver abscess and a case of infective endocarditis caused by Ruminoccocus productus, which is very rarely encountered in the clinical practice were presented. The first case was a 32 years old male who was admitted to the hospital in 2002, with the complaints of fever lasting for 20 days and pain while breathing. The abdominal ultrasonography revealed the presence of a liver abscess, and the drainage material from the abscess yielded Ruminococcus productus, identified in BACTEC 9200 (Becton Dickinson, Sparks, Md) anaerobe system. As the isolate was found to be sensitive to penicilin, the empirical gentamicin and ampicillin/sulbactam therapy was continued. The second case was a 25 years old male who was admitted to the hospital in 2005, with the signs of fever lasting for 3-4 months, chills, bone and joint pains. As multiple vegetations were detected in echocardiography, blood cultures were collected and empirical therapy with ceftriaxone and gentamicin was initiated with the preliminary diagnosis of infective endocarditis. Bacteria which were isolated from blood cultures by BACTEC 9200 system have been identified as R. productus. As this strain was also sensitive to penicillin, the empirical therapy was changed to penicilin and gentamicin. These two cases indicated that R. productus should be considered in complicated infections even if it is a rarely isolated species from the clinical samples.

Infectious complications secondary to lumbar facet injections are exceedingly rare, follow an indolent course, and local sequelae include abscess spread or infections of the central nervous system. We present the case of the development of a facet abscess and infective endocarditis, which developed shortly after a lumbar facet injection. With the increase in interventional pain procedures, physicians must be aware of potential infectious complications.

Oral Piercing is a practice that is gaining acceptance in the western world as a sign of individuality, marginality, decoration, or group membership. In a recent large-scale survey among Israeli young adults, more than half of the study population was not aware of any of the complications of oral piercing. Pain, bleeding, edema, inhalation, dental and gingival trauma, allergic reaction, contact lesions, impaired mastication, deglutition, and speech, are all potential complications of intra-oral and peri-oral piercing. Piercing can induce local as well as distant site infection and inflammation such as Ludwig's angina, endocarditis and cerebellar abscess. Moreover, Piercing is recognized as a potential vector of viral transmitting. Nevertheless, not all piercers have adequate knowledge in infection control techniques. With the increase number of patients with pierced intra and peri-oral sites, dentists should be prepared to address issues, such as potential damage to the teeth and gingival, and risk of oral infection that could arise as a result of Piercing, as well as provide appropriate guidance to patients contemplating body piercing that involve the oral sites. Since common knowledge is poor, patients should be educated regarding the dangers that may follow Piercing of the oral cavity.

After several weeks of fever and chills, a 31-year-old logger developed pain in his right thigh. Upon examination a tender, pulsating upper thigh mass was found with a long loud bruit arising from it. Severe aortic insufficiency was present; however, blood cultures were negative. An angiogram, captured blood with contrast spewing from the profunda femoral artery to fill a 5 x 10 cm sac. A false aneurysm was diagnosed and resected; numerous gram positive cocci were present in cut sections, but cultures from the cavity grew the gram negative bacteria Salmonella and Alcaligenes. After one month of intravenous ampicillin the aortic valve was replaced after being destroyed by endocarditis. Ampicillin was continued and recovery was uneventful. Mycotic aneurysms are commonly caused by Salmonella (10%), which was second only to Staphylococcus (30%). The femoral artery accounts for 38% of all mycotic aneurysms. They typically present with a pulsatile mass (52%), bruit (50%), and fever (48%). This diagnosis can be supported by leukocytosis (64-71%), positive blood cultures (50-85%), and a history of arterial trauma (51%) (injection drug use, intravascular procedure, or trauma) or endocarditis (10%).

The study deals with the incidence and clinical significance of mitral valve prolapse in the population of outpatient pediatric cardiology patients in the time period from November 1999 to April 2004. The sample included 1187 children of both sexes, 688 of whom had a structural cardiac anomaly (57.9%), and the prolapse was diagnosed in 51 children (4.3%), largely female (f:m = 7.5:1). The average age at establishing diagnosis was 12.4 +/- 2.9 years (range 6-19 years). The children were followed 3.1 +/- 0.9 years (1-4 years of age). In 25 children (49%) associated mitral valve insufficiency was found, mostly of the 1st degree (80%). During follow up, neither the progression of the insufficiency nor any other complication was observed (arrhytmia, tromboembolism) in any of the children. Dolichostenomely was found in 10 children (19.6%), and both the development of insufficiency (p = 0.464, df = 2, chi2 = 1.54) and the difference in constitution (p = 0.766, df = 4, chi2 = 1.83) were irrelevant of sex. Typical subjective symptoms were observed in 37 children (72.5%), 22 of whom were treated with beta-blockers (propranolol) (43.1%). The average age of the patients treated with 3-blockers (13.7 +/- 2.5 yr) was statistically different from the average age of untreated patients (11.5 +/- 2.9 yr), hence the probability of the influence of neurohormonal factors on the development of subjective symptoms in advanced puberty (p = 0.006, t = -2.86). The most common clinical symptom is chest-pain (95% of the group with stronger symptoms). When treated, the symptoms disappear in 82% of the patients. Mitral valve prolapse is the entity of favourable clinical course. The prophylaxis of infective endocarditis should be performed in the group with mitral insufficiency, and the children with stronger symptoms should be treated with beta-blockers.

Only about 40 cases of septic arthritis of the facet joints have been reported to date. We report 6 new cases including 2 at the cervical spine, which is rarely involved. Mean age was 61.5 years; there were 5 men and 1 woman. Spinal pain and stiffness, fever, and asthenia were the presenting manifestations. Laboratory tests consistently showed inflammation. Among classical risk factors for infection, only noninsulin-dependent diabetes was noted, in a single patient. Mean time to the diagnosis was 42 days. Discitis, a far more common condition, was considered initially, and early radiographs were of limited diagnostic assistance. Radionuclide bone scans identified the site of the infection and served to look for other foci. Magnetic resonance imaging was effective in confirming the diagnosis at an early stage and in looking for local spread (muscles, epidural space, and disk). L3-L4 was involved in 3 patients, C4-C5 in 2, and L4-L5 in 1. Direct inoculation during mesotherapy sessions was the cause in 1 patient. Cultures of blood and needle biopsy samples were positive in all 6 cases; Staphylococcus aureus was the causative agent in 3 patients. The risk of local and systemic complications governs the prognosis of facet joint infection. Of our 6 patients, 4 experienced complications: there was 1 case each of discitis, epidural infection, endocarditis, and septic arthritis of the acromioclavicular joint. Fatal multiple organ dysfunction occurred in 1 patient. In the other 5 patients, antimicrobial therapy and protection from weight-bearing for 3 months ensured a favorable outcome.

We describe a 75-year-old male patient who developed a general syndrome, with a fever of 39 degrees C, weight loss, and cervical pain, during the month following a urological procedure. The presence of positive blood cultures for Enterococcus faecalis, aortic vegetations, and severe aortic regurgitation observed with echocardiogram confirmed the diagnosis of infective endocarditis (IE). Magnetic resonance imaging of the spinal cord showed significant erosion and irregularities of the odontoid apophysis, with hyperintensity of bone marrow in T2-weighted images because of edema and inflammation. These findings suggested an infective necrosis of the odontoid apophysis. Despite the common occurrence of rheumatologic manifestations in IE, with prevalence rates of 25% to 44%, spondylodiscitis is rarely observed (5%-13%). The lumbar region is the most commonly involved. We found only one other reported case of cervical spondylodiscitis. The case we describe is the first report of septic necrosis of the odontoid apophysis associated with IE.

The records of 116 cattle suffering from cardiac disease were examined retrospectively. On the basis of the results of postmortem examinations there were 52 cases of endocarditis, 39 of pericarditis and 25 congenital cardiac defects. The most useful clinical tool for differentiating between these conditions was auscultation of the heart. The cases of pericarditis were characterised by muffled heart sounds, and the cases of endocarditis and congenital cardiac defects were characterised by a cardiac murmur. Endocarditis could be differentiated from congenital cardiac defects by the presence of a jugular pulse, venous distension, oedema, a reduced appetite, pain and polyarthritis, whereas congenital defects were associated with conformational abnormalities. These two conditions could also be differentiated by differences in the plasma sodium concentration, the albumin:globulin ratio, red blood cell count, lymphocyte count and haematocrit. The ability to differentiate between these three groups of cardiac diseases can help the veterinary practitioner in deciding whether treatment, economic salvage (slaughter for human consumption) or disposal (slaughter not for human consumption) is likely to be the best option.
