ABSTRACT
Introduction: Cryptococccus neoformans is a fungus which typically presents in immunocompromised hosts, commonly presenting as meningoencephalitis. There have been very few documented incidents of intramuscular manifestations of this pathogen. Case Report: We report on a case of a 45-year-old caucasian male with disseminated Cryptococcus neoformans who developed cryptococcal intramuscular abscesses of all extremities and osteomyelitis of the left upper limb. Clinical treatment and surgical debridement of the forearm was performed. Persistent infection resulted in a left humeral amputation and ultimately the patient's death. This is one of the few documented intramuscular abscesses of Cryptococcus neoformans. Conclusion: Orthopedic manifestations of cryptococcal infections are rare; however, awareness and prompt diagnosis may improve outcomes.
ABSTRACT
We treated a patient with pyogenic spondylitis complicated by septic shock, who was saved by emergency surgery. The patient was a 75-year-old man with back pain, fever, and weakness in the lower limbs four days before. Upon admission to our hospital, he had tachycardia, tachypnea, fever, and fluctuating vital signs. His quick sequential organ failure assessment (SOFA) score was 2. Emergent magnetic resonance imaging showed scattered intramuscular abscesses and an epidural abscess. Gram-positive cocci were detected in a blood sample. He was diagnosed with pyogenic spondylitis complicated by sepsis. Intravenous antimicrobial therapy with cefepime, vancomycin, and clindamycin was added. However, he developed tachycardia and hypotension three hours after arrival at our hospital, so he received a blood transfusion and noradrenaline and underwent emergent surgical open drainage since percutaneous drainage was difficult to perform because of scattered abscesses. Paralysis of the proximal lower extremities was recovered after surgery. Postoperatively, the causative organism was found to be methicillin-susceptible Staphylococcus aureus and intravenous antimicrobial therapy for 81 days. Three years after surgery, the patient remains free of recurrence with improvement in the activity of daily living to the extent that he could walk. The outcome of our patient suggests that surgery may be a lifesaving measure in cases whose uncontrollable vital signs by pyogenic spondylitis are complicated by sepsis. Preoperative judgment is extremely important in difficult-to-control cases because surgical invasion can be lethal.
ABSTRACT
BACKGROUND: Melioidosis is an infection caused by a facultative intracellular Gram-negative bacterium, Burkholderia pseudomallei. It can present as septicemia, localized infection with/without septicemia, asymptomatic infections, ulcers, pneumonia, visceral abscesses, neurological infection, musculoskeletal infections and can involve any organ. CASE PRESENTATION: A 56 year old Sri Lankan diabetic female presented with fever, chills and rigors for 2 weeks. She also had malaise and loss of appetite, but no other features. On examination, she was febrile (temperature was 101.4 0 F) and rest of the examination was unremarkable. Her blood culture was positive for Burkholderia pseudomallei and she was started on IV antibiotics, on day 3. During her 2nd week of hospital stay, she developed right sided low back pain with buttock pain, right hip joint pain and restricted hip joint movements suggestive of right sacroiliitis. CE CT and MRI scans confirmed the diagnosis of right iliopsoas abscesses and right sacroiliitis.Incision and drainage was performed and a pigtail catheter was left in place for continuous drainage of abscesses. Her intensive phase was initiated with IV ceftazidime 2 g every 6 h for 12 days, then changed over to IV meropenem 2 g every 8 h together with oral co-trimoxazole. 2 weeks later, oral co-trimoxazole was replaced by oral doxycycline for another 6 weeks (due to transient pancytopaenia). She made a complete and uneventful recovery with oral co-trimoxazole for another 6 months, in her eradication phase.We report this case to show the importance in early diagnosis of melioidosis, and to consider it in the differential diagnosis of multiple abscesses and to emphasize the importance in suspecting melioidosis as a causative agent in infective sacroiliitis. DISCUSSION: Melioidosis can have 2 major presentations; acute infection (symptoms lasting less than 2 months) and chronic infection (symptoms lasting more than 2 months). Musculoskeletal melioidosis is a well-recognized manifestation of the disease, which can manifest as soft tissue abscesses, septic arthritis, spondylitis, sacroiliitis and osteomyelitis.Management of melioidosis consists of 2 phases. The intensive phase and the eradication phase. These are aimed at the importance of rapidly treating the septicemia, the need of eradication of the persistent disease and the prevention of recurrent infections or relapses. The intensive phase consists of minimum 10-14 days of IV antibiotics: IV ceftazidime or IV carbapenem (meropenem/ imipenem). Eradication phase should be followed by 3-6 months of oral co-trimoxazole alone or in combination with oral doxycycline/ oral amoxiciliin-clavulanic acid.
