Subvalvular left ventricular aneurysms can be subaortic or submitral with variable etiology. This is a retrospective study of 19 subvalvular aneurysms seen in 16 cases. There were 12 isolated subaortic aneurysms, 3 isolated submitral aneurysms, and in 1 case with multiple subaortic and submitral aneurysms. Subaortic aneurysms were associated with infective endocarditis, while there seems to be a strong association between submitral aneurysms and tuberculosis. Five cases of subvalvular aneurysm has associated aneurysm sinus of Valsalva-this association suggests a congenital weakness in the attachment of aortic and mitral annuli to the underlying myocardium.

Brucellosis is a common zoonotic disease transmittable to humans from infected animal reservoirs. Malta, Rock, Gibraltar, Cyprus or Mediterranean fever, Bang's disease, intermittent typhoid or typho-malarial fever, undulant fever, etc. are just various synonyms for brucellosis. Patients suffering from this disease show unspecific symptoms, e.g. fever, chills, malaise, arthralgia, headache, tiredness and weakness. Human brucellosis may be caused by four of totally six genetically and phenotypically closely related Brucella species, i.e. B. melitensis, B. abortus, B. suis and B. canis. Although many organ systems may be involved, brucellosis is rarely fatal. Therapeutic failure and relapses, chronic courses and severe complications like bone and joint involvement, neurobrucellosis and endocarditis are characteristic for the disease. A definite diagnosis requires the isolation of Brucellae from blood, bone marrow or other tissues. However, cultural examinations are time-consuming, hazardous and not sensitive. Thus, clinicians often rely on the indirect proof of infection. The detection of high or rising titers of specific antibodies in the serum allows a tentative diagnosis. A variety of serological tests has been applied, but at least two serological tests have to be combined to avoid false negative results. Usually, the serum agglutination test is used for a first screening and complement fixation or Coombs' test will confirm its results. As Brucella ELISAs are more sensitive and specific than other serological tests, they may replace them step by step. This review will summarize advantages and disadvantages of the serological techniques used in clinical laboratories for indirect verification of human brucellosis.

A cerebrovascular thromboembolic event may precede the identification of cancer, and be the first clinical evidence of an underlying malignancy. The malignancy can cause either nonbacterial thrombotic endocarditis or hypercoagulable state, both of which may have clinical manifestions such as thrombotic or embolic occlusion of multiple major cerebral vessels. We present three cases with unusual cerebrovascular events. The first case is a 62-year-old woman who was admitted due to acute left limbs weakness and consciousness disturbance. Brain computed tomographic (CT) scan showed right middle cerebral artery (MCA) and posterior cerebral artery (PCA) infarctions with uncal herniation. The second case is a 44-year-old woman who was hospitalized due to acute bilateral limb weakness and consciousness disturbance. Bilateral MCA, left PCA, anterior cerebral artery (ACA) infarctions and deep vein thrombosis in the left leg were diagnosed. The third case is a 63-year-old man who developed sudden onset of right hemiplegia and consciousness disturbance. Brain CT scan showed bilateral MCA and left ACA infarction. The results of a series of examinations including biochemistry, lipid profile, carotid duplex, and transthoracic and transesophageal echocardiography were unremarkable. All patients had positive disseminated intravascular coagulation (DIC) tests with elevated D-dimers and fibrinogen degradation products (FDP). Further systemic evaluation for malignancy revealed ovarian cancer in the first patient, endometrial carcinoma in the second patient, and adenocarcinoma of lung in the third patient. They all died of the underlying malignancy. Because the hemostatic system can be altered by malignancy, intravascular coagulation abnormalities of these malignancy-related strokes may be disclosed by laboratory assays of hemostasis.

A 75-year-old woman with infective endocarditis developed critical illness polyneuropathy (CIP) with quadriplegia after cardiac surgery. The quadriplegia resolved gradually after aggressive treatment of the underlying infection and with rehabilitation. However, a MEDLINE search of the English-language literature failed to yield results matching quadriplegia and infective endocarditis. CIP is a complication of septic syndrome and sepsis. This complication has been largely unrecognized in intensive care units owing to difficulties in performing a clinical examination or electrophysiologic studies. Difficulty in weaning from the ventilator is an important early manifestation of CIP. Electroneuromyography (ENMG) should be routinely performed to establish the diagnosis. We suggest that any septic patients with unexplained muscle weakness, paralysis, or difficulty in weaning from the ventilator should be evaluated for CIP.

Botryomycosis is a rare bacterial infection of the skin and, rarely, viscera that is characterized by the formation of characteristic hyaline grains. We encountered a patient with Erysipelothrix rhusiopathiae endocarditis who developed visceral botryomycosis. He was a 54-year-old black man who presented in sepsis with a history of progressive weakness and severe weight loss. He died 10 hours after admission. At autopsy, endocarditis was identified, along with infarcts of the spleen and kidneys. Microscopically, visceral botryomycosis was seen. With these bacteria, an animal source is usually identified, although one was not found in this man. Erysipelothrix rhusiopathiae is an organism that is becoming identified in a range of infections in humans, the manifestations and pathophysiology of which are still being discovered.

We report the case of a 71-year-old woman who presented with persistent high fever and progressive weakness for 10 days. Klebsiella oxytoca infective endocarditis was diagnosed based on four sets of positive blood culture of K. oxytoca together with fluttering vegetation (0.6 cm in diameter x 1.3 cm long) on the base of the anterior mitral leaflet. The diagnosis was documented using transthoracic and transesophageal echocardiograms. After 4 weeks of intravenous cefazolin therapy, the patient completely recovered.

Streptococcus suis is a zoonotic pathogen which causes meningitis, bacteremia, and endocarditis in pigs. Human infection is rare and often presents as meningitis with the sequela of permanent deafness and endocarditis. Previous cases were reported from pig-rearing countries such as Holland and Hong Kong. We report a 55-year-old bedridden man with S. suis meningitis complicated with ventriculoperitoneal shunt infection and lumbar spine spondylodiscitis. He presented with fever, delirium, neck stiffness, lower leg weakness and sudden onset hearing loss for several days. He was successfully treated with intravenous antibiotics, ventriculoperitoneal shunt replacement, lumbar spinal laminotomy and discectomy. Cerebrospinal fluid culture initially misidentified the organism as Streptococcus acidominimus, and S. suis was later identified by 16S rRNA sequencing. Misidentification of the microbiological findings may lead to a failure to correctly diagnose this disease. S. suis meningitis should be included in the differential diagnosis of patients with meningitis and sudden hearing loss.

We report on a 67-year-old female patient who was admitted to our intensive care unit with acute renal failure and severe hypoxemia. Transiently, the patient had to be treated with kidney replacement therapies and artificial ventilation. The actual illness started with general weakness, recurrent bloody diarrhea and intermittent dermatitis of the lower legs. Skin symptoms were initially observed 2 years before the actual clinical findings. The bloody diarrhea was attributed to an inflammatory stenosis of the sigma. The life-threatening clinical aggravation was due to diffuse alveolar hemorrhage and alveolitis. In the search for the cause of the systemic disease, both a monoclonal y-globulinemia, causing a cryoglobulinemia type II and an acute cytomegalovirus infection were diagnosed. Additionally, the course of the disease was complicated by a secondary antibody deficiency as well as an endocarditis of the aortic valve caused by Enterococcus faecium. A cryoglobulinemic vasculitis type II was histologically found in biopsy specimen of the kidney. Thus, the present case reports on a coincidence of a monoclonal gammopathy causing a cryoglobulinemia type II with extensive organ involvement and a florid CMV infection. We hypothesize that the CMV infection has triggered the cryoglobulinemia and its particular severe organ involvement.

A 4-yr-old male ferret (Mustela putorius furo) was presented with a 3-day history of pelvic limb ataxia and weakness. A cellulitis associated with a deep bite wound was identified and initially treated with antibiotics and anti-inflammatory medication. Two weeks later, a grade IV/VI cardiac murmur was identified on physical examination. Echocardiographic examination revealed irregular thickening of the aortic valve leaflets, with normal chamber dimensions and normal systolic function. The ferret's physical condition rapidly deteriorated and it was subsequently euthanatized. Myxomatous degeneration of the aortic valve leaflets, with ulceration and vegetative lesions, and multiorgan infarctions were identified during necropsy. A bacterial etiologic agent was not identified from blood culture or histopathology. Lesions present were consistent with nonbacterial thrombotic endocarditis, a novel condition in the ferret.

A 53-year-old woman presented with a ruptured intramedullary aneurysmal dilatation fed by the anterior spinal artery associated with an arteriovenous malformation located in the ventral cervical spinal cord. She developed tetraparesis and respiratory dysfunction. The neurological deterioration was caused by hematomyelia due to the ruptured aneurysmal dilatation and progression of edema in the upper cervical spinal cord due to venous hypertension associated with additional hematoma in the medulla oblongata. Endovascular embolization of both C-1 and C-2 radicular arteries was performed with Guglielmi detachable coils, but components fed by small branches such as the radiculo-pial artery were not obliterated. Surgery was performed for extirpation of the arteriovenous malformation and cervical intramedullary hematoma, and excision of the aneurysmal dilatation through a transcondylar approach combined with vertebral artery transposition. Postoperatively, she overcame several complications such as pneumonia and endocarditis, and had only moderate weakness of the right upper and lower limbs. This case indicates that surgical intervention for high cervical intramedullary lesion may be very effective.
