The relationship between Staphylococcus aureus bacteremia and bacteriuria was studied over a five year period in three hospitals. In a Veterans Administration Hospital, 59 patients with Staph, aureus bacteremia had a urine culture within 48 hours of a positive blood culture. In 16 of 59 (27 per cent), greater than 10(5) Staph. aureus was recovered from the urine in pure culture. Six of these patients had apparent primary staphylococcal urinary tract infection. Clinical and laboratory parameters in the patients with staphylococcal bacteremia and bacteriuria were compared with those in 31 patients with staphylococcal bacteremia and sterile urine cultures. The two groups differed only in the more frequent occurrence of pyuria and proteinuria in the bacteriuric patients. In two other hospitals, staphylococcal bacteriuria occurred in 7 per cent of patients with Staph. aureus bacteremia and in 13 per cent of cases of staphylococcal endocarditis. Review of autopsy records for 33 patients who died within one month of their bacteremia failed to show a correlation between bacteriuria and the presence of renal abscess. Staphylococcal bacteriuria is a frequent and unexplained concomitant of Staph. aureus bactremia.

A 60-year-old woman returned from visiting a cousin in Texas. For the past 6 weeks, she had not been feeling well and had lost almost 30 lb. She had frequent night sweats, although she did not recall having taken her temperature. Upon evaluation in the emergency department, results of physical examination were notable for cachexia and poor dentition. She was noted to have pyuria, and therapy was initiated for a urinary tract infection. Results of blood cultures performed the same day were positive for gram-positive cocci, and vancomycin therapy was initiated. She developed difficulty in seeing to her, left and a computed tomographic scan of the brain was performed; results were interpreted as negative. A transesophageal echocardiogram showed a 3-cm mass attached the posterior leaflet of the mitral valve. Initial interpretation was of an atrial myxoma. One of the authors was asked to consult on the case and noted bilateral conjunctival hemorrhages (Figure 1). Subsequently, the blood culture isolate was identified as Streptococcus mitis. Magnetic resonance imaging confirmed multiple cerebral infarcts consistent with embolic origin. The patient underwent emergent cardiac surgery, and her mitral valve was replaced with a bioprosthetic valve. She successfully completed a 4-week course of antibiotic therapy for her endocarditis.

A severely ill 65-year-old man presented with symptoms of shortness of breath, edema and vasculitidic purpura over his lower extremities. He had severe mitral regurgitation which had not been surgically treated. Hematologic examination demonstrated leukocytosis with profound anemia. Other blood tests revealed impaired renal function, hypoalbuminemia, hypocomplementemia and mixed-type cryoglobulinemia. Urinalysis showed proteinuria, hematuria and pyuria, typical of a nephritic sediment. Renal biopsy indicated diffuse proliferative glomerulonephritis and a "full house" deposition in immunofluorescence study (positive for C3, C4, C1q, IgG, IgA and IgM), resembling the pathologic findings in class IV lupus nephritis. Although subacute bacterial endocarditis was initially suspected owing to a history of a predisposing valvular heart disease, probable vegetation shown by cardiac sonography and a clinical picture suggestive of a chronic infection, it was thought unlikely due to the entire afebrile course and initial sterile blood cultures. However, the blood cultures repeated 2 weeks after admission grew 3 sets of viridans streptococci. Following a course of penicillin and gentamicin treatment, his renal function, anemia and abnormal urine sediments improved gradually. Diffuse proliferative glomerulonephritis is well known to occur in infective endocarditis. However, the "full house" immunostaining in immunofluorescence study has never been reported. This case adds a new entity to the differential diagnosis of "full house" immune complex-related glomerulonephritis and exemplifies the need to maintain a high index of suspicion for underlying infectious disorders when facing glomerulonephritic or vasculitic syndrome.

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 56-year-old man with a history of uncontrolled type 2 diabetes mellitus, benign prostatic hypertrophy and history of recent knee and elbow abscess presented to the emergency department with nausea, vomiting, and fevers. Two days prior, he presented to the ER and was diagnosed with acute presumed prostatitis and urinary retention. He was discharged on ciprofloxacin and an indwelling Foley catheter with urology follow-up. After being unable to tolerate oral medications, he presented again to the emergency department, at which time, he was febrile and tachycardic. Physical exam was benign except for a boggy and tender prostate and bilateral CVA tenderness. Labs demonstrated leukocytosis, elevated HbA1C, and pyuria on urinalysis. Urine cultures collected at the patient's earlier emergency department visit demonstrated no growth. Computed tomography indicated an enlarged prostate with patchy areas of low density. He was admitted with sepsis secondary to prostatitis. Blood cultures on day one showed gram-positive cocci , methicillin resistant staph aureus (MRSA isolate) and persistent bacteremia for three days despite therapy with vancomycin. After adequate dosing of vancomycin, sterilization of the blood was achieved, yet urine culture demonstrated growth of MRSA. Transthoracic rchocardiogram (TTE) showed no signs of endocarditis with good visualization of valves. He was successfully treated with 14 days of vancomycin.
