Group B streptococcal bacteremia with septic arthritis is a rare complication of second trimester dilation and evacuation, and may cause substantial post-operative morbidity. A 37-year-old gravida 4 para 1-0-2-1 presented with fever and right hip pain on post-operative day 11 from a second trimester dilation and evacuation for fetal trisomy 21. She was initially found to have septic arthritis involving the right sacroiliac joint and group B streptococcal bacteremia. Transesophageal echocardiogram showed a tricuspid valve, vegetation consistent with endocarditis. After prolonged parenteral antibiotic therapy, she developed septic pulmonary emboli that were successfully treated with anticoagulation therapy. Group B streptococcal infection is a potentially serious post-abortion complication that can cause sacroiliitis, endocarditis and septic pulmonary emboli.

The occurrence of Brucella endocarditis following Bentall operation is a rare and life threatening condition, particularly when it is complicated by development of a pseudoaneurysm. Here we present a 40-year-old veterinarian with bicuspid aortic valve, who developed type A aortic root dissection and required Bentall operation. His past medical history was positive for an episode of treated brucellosis. Four months after the operation, he developed signs, symptoms and serological findings of brucellosis for the second time and was treated with antibiotics. Then after he was well untill about 14 days prior to his recent admission, when he again developed hip pain, fever, shortness of breath, profound fatigue and weakness. His transthoracic echocardiography was suggestive of endocarditis. A transesophageal echocardiogram revealed detachment of valve-conduit from the annulus and the mitral-aortic intervalvular fibrosa and the presence of a large aortic pseudoaneurysm with multiple vegetations attached to its Dacron walls. A huge pseudoaneurysm was detected at surgery and the whole valve-conduit was replaced with a 25 mm homograft. Blood and vegetation cultures turned to be positive for Brucella melitensis. Early echocardiographic diagnosis and prompt surgical intervention were helpful for survival of our patient who had aortic pseudoaneurysm complicated by Brucella endocarditis.

The unique aspect of this case study is the unusual history, presentation, ultrasonography, MRI and blood culture results, which lead to the diagnosis and treatment of adductor pyomyositis with a rare organism in a temperate country. The patient presented with a one-day history of malaise, fever, left groin pain and inability to weight bear on the left leg. There was no history of any trauma, predisposing infections or recent travel. Plain radiograph and ultrasound of the hip was normal with no effusion. Two consecutive blood cultures suggested Streptococcus mitis bacteraemia and MRI scan confirmed pyomyositis of the left hip adductors that was too small to drain. S. mitis is a normal commensal organism however it can lead to opportunistic infections particularly endocarditis. Echocardiogram revealed no cardiac complications, in particular no endocarditic vegetation. Patient was treated with intravenous benzylpenicillin for a week followed by oral phenoxymethylpenicillin for a week. Adductor pyomyositis must be considered as a differential diagnosis in a child with unusual presentation of hip pain. When an ultrasound is normal, MRI scan is warranted to confirm diagnosis. Septic screen should include blood cultures. The commonest causative organisms are the Staphylococcus family. However if S. mitis is isolated, cardiac sources of infection resulting in septic emboli must be investigated. Repeated MRI scans are required particularly if the patient does not respond to medical management.
