Pyogenic liver abscesses usually develop secondary to biliary tract and intraabdominal infections and members of the Enterobacteriaceae family are usually implicated as the etiologic agents. In this report a case of hepatic abscess devoloped secondary to cervical lymphadenitis caused by Staphylococcus aureus, was presented. Twenty-one years old male patient was admitted to the hospital with complaints of fever, swelling and pain at the right side of the neck and difficulty in swallowing. Physical examination revealed painful submandibular lymphadenopathy with hyperemia. Upon demonstration of cystic lymphadenopathy by magnetic resonance imaging of the neck, the mass was aspirated. Gram-positive cocci with abundant leucocytes were detected in Gram stained smears of the aspiration material and methicillin-susceptible S. aureus (MSSA) was identified in the culture. Treatment with ampicillin/sulbactam (4 x 1.5 g/day) was initiated. However, since patient still had fever and abdominal pain, nausea and vomitting were also added to his complaints, abdominal ultrasonography and computerized tomography (CT) were done and abscesses were demonstrated in liver. The abscesses were drained under CT guidance and the fever of the patient resolved. Treatment with ampicillin/sulbactam was continued for 6 weeks. Although it was considered that the hematogenous spread of MSSA that led to cervical lymphadenitis caused the hepatic abscesses, the agent was neither isolated from the blood culture nor from the hepatic abscess material. It should always be taken into consideration that liver abscesses might accompany distant infections and antibiotic therapy alone might not be sufficient for the complete resolution of such infections.

Staphylococcus lugdunensis is an infrequent cause of infective endocarditis (IE) and usually involves native valves of the heart. It causes life-threatening events such as rupture of cardiac valve or cerebral or pulmonary embolism due to necrosis on the endocardial tissue involved by the bacteria. Antibiotic therapy without cardiac surgery or delayed cardiac surgery usually follows a fatal course in S. lugdunensis endocarditis. In this report the first case of S. lugdunensis endocarditis from Turkey was presented. A 37-year-old man was admitted to the emergency department with a 2-weeks history of fever chills and accompanying intermittent pain on the left side of the thorax. Other than recurrent folliculitis continuing for 20 years, his history was unremarkable. Echocardiography revealed vegetation on the mitral valve of the patient and vancomycin plus gentamicin were initiated with the diagnosis of IE. All blood cultures (5 sets) taken on admission and within the initial 48 hours of the antibiotic therapy yielded S. lugdunensis. According to the susceptibility test results, the antibiotic therapy was switched to ampicillin-sulbactam plus rifampin. Blood cultures became negative after the third day of therapy, however, cardiac failure was emerged due to rupture of mitral valve and chorda tendiniea on the 12th day of the therapy. Cardiac surgery revealed that mitral valve and surrounding tissue of the valve were evidently necrotic and fragile, anterior leaflet of the mitral valve was covered with vegetation, posterior leaflet and chorda tendiniea were ruptured. Vegetation was removed and the destructed mitral valve was replaced with a mechanical valve. Vegetation culture remained sterile, however, antibiotics were switched to vancomycin plus rifampin due to persistent fever on the 21st day of the therapy (9th day of operation). Fever resolved four days after the antibiotic switch. Antibiotics were stopped on the 9th weeks of admission and the patient was discharged. He had no problem in follow-up controls for one year. In conclusion, proper antibiotic therapy combined with early cardiac surgery seems to be the optimal therapeutic approach in IE caused by S. lugdunensis.

The current US guidelines advise that all women colonized with Group B streptococcus (GBS) at 35-37 weeks, as well as those laboring before this time and all women with GBS urinary tract infections, should be offered intrapartum antibiotic prophylaxis, usually in the form of high-dose intravenous penicillin or ampicillin, unless delivered by planned cesarean section before the onset of labor in a woman with intact membranes. In term and preterm babies who are born to treated women, in addition to babies who act ill, the recommendation is to treat the baby with antibiotics. In certain circumstances, such as when the mother receives an intrapartum antibiotic < 4 hours prior to delivery, the baby receives antibiotics even if the baby appears well. This paper proposes a new process for testing for GBS that involves using the umbilical cord. If this process were used, babies would not need to have blood drawn and would experience less pain.

We describe an unusual case of Lactobacillus casei bacteraemia in a heavy dairy consumer woman, with a one month history of low grade fever and admitted to our hospital for sudden onset of severe thoracic pain due to dissection of the aortic arch and ascending aorta. The patient underwent four weeks of intravenous ampicillin (2 g every 4 hours) followed by 2 weeks of oral amoxicillin (1 g every 8 hours) with resolution of fever, thoracic pain and progression of aortic disease. On the basis of the patient's symptoms, a possible penetration of L. casei in an aortic wall defect with development of aortic dissection is hypothesized.

Purpose. To describe the clinical characteristics, diagnosis, and treatment with intravitreal ampicillin sodium of a postoperative endophthalmitis case due to Streptococcus uberis; an environmental pathogen commonly seen in mastitis cases of lactating cows. Methods. Case Report. A 52-year-old, Hispanic diabetic patient who suddenly developed severe pain and severe loss of vision, following vitrectomy. Results. The patient was diagnosed with postoperative endophthalmitis secondary to a highly resistant strain of Streptococcus uberis that did not respond to intravitreal antibiotics. He was treated with an air-fluid interchange, anterior chamber washout, intravitreal ampicillin sodium (5 mg/0.1 mL), and silicon oil tamponade (5000 ck). The eye was anatomically stabilized, though there was no functional recovery. Conclusion. Streptococcus uberis is an uncommon pathogen to the human eye, which has unique features that help the strain in developing resistance to antibiotics. While treatment with intravitreal ampicillin is feasible, there are still concerns about its possible toxicity.

Sphingomonas paucimobilis (S. paucimobilis), is a gram-negative, aerobic, non-fermentative, oxidase (+) and catalase (+) bacterium. Although S. paucimobilis is isolated very rarely, it can cause both nosocomial and community-acquired infections. A patient admitted to our clinic had a complaint of swelling in the right mandibular region and pain increasing while eating for the previous week. Bimanual palpation revealed a painful swelling of 1x1x1 cm in size inside the right Wharton's duct. Via massage over the right submandibular gland, a purulent drainage came up from the opening of the Wharton's duct and it was cultivated and S. paucimobilis was isolated. There was no ultrasonographic evidence of calculi in the duct or in the gland, but during the right submandibular gland massage, two stones came out through the Wharton's duct. The infection was observed to be eradicated with a 14-day ampicillin-sulbactam treatment. In the control examination after six months, there were no pathological signs or symptoms and the ultrasonogram was normal. As far as we know, this is the first sialadenitis case with underlying sialolithiasis where S. paucimobilis was isolated.

A 65-year-old man who had suffered from traumatic spinal cord injury had chronic lumbar pain. He had exacerbation of lumbar pain and intermittent fever and consulted several doctors, but the cause of the lumbar pain was unknown. An orthopedic specialist took an MRI. Spinal MRI showed increased signal intensity at the level of T10-11 and a mass in his right lower lung field, so he was referred to our hospital. Two transbronchial lung biopsy procedures failed to obtain malignant cells. CT guided biopsy showed fibrous and hyalinizing tissue contained plasma cells and lyphocytes. Staphylococcus aureus was cultured from the second bronchial lavage fluids of brush and blood cultures, so we began administration of ampicillin-sulbactam. Avoiding threatened or actual cord compression due to collapse resulting from spinal instability, posterior fusion with instrumentation was done through the back of his chest wall. At once, bone biopsy was done, and showed no malignant cells. As soon as antibacterial treatment was stopped after the operation, he had bloody sputa and fever. The antibacterial agent was resumed and the symptoms improved. The mass decreased in size and lumbar pain improved gradually, so we concluded the diagnosis was pyogenic spondylitis caused by S. aureus. After about 5 months of antibacterial treatment, the tumor substantially diminished.

The concurrence of acute coronary syndrome with allergy or hypersensitivity as well as with anaphylactic or anaphylactoid reactions is increasingly encountered in daily clinical practice. There are several reports associating mast cell activation with acute cardiovascular events in adults. This was first described by Kounis as 'allergic angina syndrome',progressing to 'allergic myocardial infarction'. The main mechanism proposed is the vasospasm of coronary arteries. We present a case of a 28-year-old man who was admitted to our hospital with thoracic pain and dyspnoea. The symptoms recurred after simultaneous use of 1 g amoxicillin/clavulanic acid orally and 1 g ampicillin/sulbactam parenterally for tonsillitis the night before presentation and on the morning of admission.

A 49-year-old man with fever, pain in both legs, purpuras and cyanosis was admitted to hospital. He was a heavy drinker, but did not have diabetes or other immunosuppressive disease. On admission, he was in shock, with haematological findings suggestive of disseminated intravascular coagulation, and liver and kidney failure. The presence of a scratch wound on his face caused by a cat, and linear, Gram-negative rods phagocytosed by polynuclear leucocytes on peripheral blood smear suggested Capnocytophaga canimorsus infection. On day 1, antibiotics (ampicillin/sulbactam) and catecholamines were initiated. The patient required haemodialysis three times per week for 3 weeks. His toes became necrotic but improved and amputation was not necessary. On day 52, he was discharged from hospital with only mild sensory impairment of the legs.

We present an uremic patient on chronic hemodialysis with splenic septic emboli associated with active infective endocarditis and anaerobic bacteremia complicated by ruptured spleen. A 62-year-old female patient was admitted because of fever and pain in the left upper abdomen and swelling and hematoma around the left brachiocephalic arteriovenous fistula. Transthoracic echocardiography revealed mobile hyperechoic mass (vegetation) on the anterior mitral valve. Abdominal ultrasound scan showed multiple hypoechoic lesions of the enlarged spleen, described as possible necroses or abscesses, and computed tomography showed low-density inhomogeneous lesions in the enlarged spleen with large perisplenic hematoma, with spleen rupture. Blood culture revealed anaerobic Gram-negative bacilli ( Bacteroides spp.), ampicillin resistant. This is the first report of splenic rupture associated with anaerobic bacteremia and splenic septic emboli in a uremic patient on chronic hemodialysis. Splenic septic emboli with abscess/infarction in hemodialysis patients are a rare disorder but could be a consequence of dialysis access site infection and might predispose to splenic rupture. Ultrasound scan of abdomen is fast, inexpensive and easy to perform. As mortality is high, early surgical intervention on vascular access is mandatory.
