The reported incidence of deep soft-tissue infections after RCR ranges between 0.3% and 1.9%. Deep shoulder infection after RCR appears uncommon, but the actual incidence may be higher as many cases may go unreported. Clinical presentation may include increasing shoulder pain and stiffness, high temperature, local erythema, swelling, warmth, and fibrinous exudate. Generalized fatigue and signs of sepsis may be present in severe cases. Varying clinical presentation coupled with a low index of suspicion may result in delayed diagnosis. Laboratory findings include high erythrocyte sedimentation rate and C-reactive protein level, and, rarely, abnormal peripheral blood leucocyte count. Aspiration of glenohumeral joint synovial fluid with analysis of cell count, gram staining and culture should be performed in all patients suspected with deep shoulder infection after RCR. The most commonly isolated pathogens are Propionibacterium acnes, Staphylococcus epidermidis, and Staphylococcus aureus. Management of a deep soft-tissue infection of the shoulder after RCR involves surgical debridement with lavage and long-term intravenous antibiotic treatment based on the pathogen identified. Although deep shoulder infection after RCR is usually successfully treated, complications of this condition can be devastating. Prolonged course of intravenous antibiotic treatment, extensive soft-tissue destruction and adhesions may result in substantially diminished functional outcomes.展开更多

However, immunocompromised hosts and older adults with complex medical conditions may develop a complicated form of bacteraemia, with a high mortality rate involving extra-intestinal foci of infection and mycotic aneurysms. We report the case of a 61-year-old man with poorly controlled diabetes mellitus, hypertension, dyslipidaemia, and congestive heart failure, who presented with unilateral left lower limb swelling, extensive deep vein thrombosis, and concomitant Salmonella bacteraemia. An oral anticoagulant and intravenous antibiotic therapy were initiated. Although the patient remained haemodynamically stable, he complained of constant left lower limb weakness and lower back pain. A computed tomography angiography scan of the thorax and abdomen revealed saccular aneurysms with contained hematoma of the left common iliac artery. The oral anticoagulant was discontinued, and an inferior vena cava filter was inserted as part of the venous thrombosis management. The patient was offered aorto-uni-iliac endovascular aneurysm repair and received intravenous antibiotic therapy, postoperatively, for six weeks. The postoperative blood cultures remained negative, and he was discharged with a course of ciprofloxacin administered orally. However, three months after the surgery, the patient died of recurrent septicaemia. This case illustrates the importance of remaining vigilant for potential endovascular complications of Salmonella bacteraemia, such as mycotic aneurysms and deep vein thrombosis, among high-risk patients. Further, this case highlights the challenges of eliminating Salmonella bacteraemia and its related complications, albeit treating it with both a prolonged course of medical therapy and surgical intervention.展开更多
