Primary Psoas Abscess Complicated by Septic Arthritis Due to Community-Acquired Methicillin-Resistant Staphylococcus aureus: A Case Report and Review of Literature.

This is a report of an unusual case of a primary psoas abscess due to community-acquired methicillin-resistant Staphylococcus aureus (MRSA) in an immunocompetent man. The course of the disease is expressed as septic arthritis of the hip joint with avascular necrosis. Diagnosed one month after symptoms began, the patient was treated by surgical evacuation of the abscess and appropriate antibiotics. Full recovery and return to his usual activity followed total hip replacement.

Acute Respiratory Distress and Hyperchloremic Metabolic Acidosis as a Result of Massive Irrigation Fluid Extravasation After Arthroscopic Shoulder Surgery: A Case Report and Recommendations for Preventable Complications.

BACKGROUND Airway compromise caused by massive fluid extravasation in association with arthroscopic shoulder surgery is rare. However, it is even more rare to occur as a result of pleural effusion. We present this case to increase the awareness of this rare complication and show how to minimize the likelihood of this uncommon incident. CASE REPORT We describe a case of a 68-year-old woman who underwent elective shoulder arthroscopy for rotator cuff repair. She had immediate postoperative shortness of breath and was found to have bilateral pulmonary edema and pleural effusion accompanied by metabolic acidosis. She was managed conservatively in the intensive care unit and then transferred to the general ward after clinical and radiological improvement the next day. CONCLUSIONS This uncommon complication was self-limiting, and the patient recovered uneventfully. High clinical suspicion is required to address this event so proper rapid management can be made.
