Infected upper extremity aneurysms: a review.

Coagulase-negative staphylococci (CoNS) are part of the microbiota of human skin and rarely linked with soft tissue infections. In recent years, CoNS species considered as one of the major nosocomial pathogens and can cause several infections such as catheter-acquired sepsis, skin infection, urinary tract infection, endophthalmitis, central nervous system shunt infection, surgical site infections, and foreign body infection. These microorganisms have a significant impact on human life and health and, as typical opportunists, cause peritonitis in individuals undergoing peritoneal dialysis. Moreover, it is revealed that these potential pathogens are mainly related to the use of indwelling or implanted in a foreign body and cause infective endocarditis (both native valve endocarditis and prosthetic valve endocarditis) in patients. In general, approximately eight percent of all cases of native valve endocarditis is associated with CoNS species, and these organisms cause death in 25% of all native valve endocarditis cases. Moreover, it is revealed that methicillin-resistant CoNS species cause 60 % of all prosthetic valve endocarditis cases. In this review, we describe the role of the CoNS species in infective endocarditis, and we explicated the reported cases of CoNS infective endocarditis in the literature from 2000 to 2020 to determine the role of CoNS in the process of infective endocarditis.

Background and purpose Mycotic aneurysm poses a high risk of mortality. This study evaluated the demographic and clinical characteristics and outcomes of hospitalized patients with mycotic aneurysm. Methods Patients with mycotic aneurysm hospitalized between March 1996 and May 2006 at a medical center in southern Taiwan were retrospectively analyzed. Results Fifty two patients (38 men and 14 women; mean age, 64.5 +/- 15.6 years) were included. The leading underlying diseases were diabetes mellitus (40.4%), hypertension (21.2%), and renal disease and heart disease (19.2% each). The most common pathogens isolated from blood and/or resected tissue were Salmonella spp. (34.6%), Klebsiella pneumoniae (11.5%) and Staphylococcus aureus (11.5%). Mycotic aneurysms caused by Gram-negative bacilli were significantly more likely to occur in older patients (p=0.018) and at infrarenal sites (p=0.021). There were trends suggesting that mycotic aneurysms were more likely to be caused by Gram-negative bacilli in patients receiving steroid treatment and in those with underlying diabetes mellitus. Mycotic aneurysms caused by Gram-positive cocci were significantly more likely to occur in suprarenal arteries (p=0.048), especially intracranially (p=0.002), in younger patients (p=0.018) and in patients with concurrent endocarditis (p=0.008). The overall in-hospital mortality rate was 30.6%, and there was no significant difference in in-hospital mortality between mycotic aneurysms caused by Gram-negative bacilli and those due to Gram-positive cocci. Conclusions The relationship between the anatomic site of mycotic aneurysm and the spectrum of culprit bacteria may help clinicians promptly choose appropriate antibiotic regimens on an empirical basis. Further study is required to understand better the role of K. pneumoniae in mycotic aneurysm in Taiwan.

Artropatía psoriásica complicada con amiloidosis secundaria

We report the case of a 48 year old male with human immuno-deficiency virus and hepatitis C virus infection and previous grafting of a thoracic aortic aneurysm. He returned from a trip to India with fever and in a poor physical condition. Diagnostic work-up revealed septicaemia with staphylococcus aureus, infection of the aortic graft with covered rupture of the proximal anastomosis and mitral valve endocarditis. Following antibiotic therapy, implantation of a transcutaneous endovascular aortic prosthesis and mitral valve repair were performed. During the postoperative period, the patient complained of pain and a palpable pulsating mass in the right cubital fossa. Ultrasound scan revealed a pseudoaneurysm at the brachial artery bifurcation. Since there were no signs of venous puncture in this area, we assumed this to be a mycotic pseudoaneurysm resulting from septic embolism. In the absence of clinical signs of inflammation, this pseudoaneurysm was successfully treated by ultrasound-guided thrombin injection. Irrespective of the cause for this mycotic pseudoaneurysm of the brachial artery, percutaneous ultrasound-guided thrombin closure in combination with antibiotic therapy might be a feasible, safe, cheap and minimally-invasive alternative to surgery.
