    Melioidosis as a cause of femoral osteomyelitis and multifocal intramuscular abscess around the hip joint in a farmer: a case report
    (Sri Lankan Society for Microbiology, 2013) Rodrigo, K.M.D.; Premaratna, R.; de Silva, H.J.; Corea, E.
    Melioidosis is a potentially fatal infectious disease caused by the soil transmitted saprophyte Burkholderia pseudomallei. Though Sri Lanka being considered a non endemic country, with the increasing number of cases reported recently there is mounting evidence that the disease is emerging here. Osteomyelitis caused by Burkholderia psuedomallei infection is uncommon and only few cases were found in the literature. We report a case of proximal femoral osteomyelitis and multifocal intramuscular abscess around the hip joint caused by Burkholderia psuedomallei in a Sri Lankan farmer. A 57 year old Sinhalese male farmer was admitted with intermittent high grade fever and left hip pain for 3 weeks. He was found to have diabetes. Ultrasound scan of the left hip joint revealed a joint effusion of 1 cm. Whole body anterior and posterior delayed images of a Tc-99m MDP bone scan demonstrated intense tracer uptake in the left proximal femur and the CT pelvis revealed a left side multi focal intramuscular abscess around the hip joint and proximal femur osteomyelitis. The CT guided aspiration of the intramuscular abscess fluid yielded a growth of gram negative bacilli, identified as pseudomonas species. Blood for antibodies for Burkholderia psuedomallei revealed a positive result at a titre of 1:320. He was diagnosed as having probable melioidosis with multifocal intramuscular abscess around the left hip joint and left proximal femoral osteomyelitis. He responded to intravenous meropenem 1 g twice a day and was continued for 4 weeks and was discharged on maintenance regime of oral cotrimoxazole 1920 mg twice a day and oral doxycycline 100 mg twice a day for 20 weeks. Our patient remained asymptomatic after 6 months of follow up and a subsequent ultrasound and CT images showed full resolution of the osteomyelitis and failed to demonstrate any abscess formation. This case alerts clinicians regarding the unusual aetiology of osteomyelitis caused by Burkholderia psuedomallei especially in patients with diabetes and those who have prolonged contact with soil. In such situations early institution of appropriate antibiotics will be life saving and a prolonged maintenance therapy with oral antibiotics is essential to prevent recrudescence of the infection.

    Repeated dengue shock syndrome and "Dengue myocarditis" responding dramatically to a single dose methyl prednisolone
    (Sri Lanka Medical Association, 2012) Premaratna, R.; Rodrigo, K.M.D.; Anuratha, A.; de Alwis, V.K.D.; Perera, U.D.C.A.; de Silva, H.J.
    INTRODUCTION: Place of steroids in the management of severe dengue is unclear. A retrospective observational study appeared to show benefit of methylprednisolone (MP) in a highly selected group of patients. CASE REPORT: A 14-year-old schoolboy developed "myocarditis" (4th day) and on the fifth day, he collapsed with Dengue shock syndrome DSS needing rapid resuscitation with intravenous fluid boluses and dextran. He continued to have high fever (39-410C), and pulse rate (PR)>110/min and developed two further episodes of DSS and was resuscitated with further boluses of dextran. As there was no response with temperature 40.20C, PR 160/min, mid-arm systolic BP 70 mmHg, confused, restless, respiratory rate 36/min, dropping capillary 02 saturation, moderate pleural effusions and ascites, urine output <0.2ml/kg/Hr, made it extremely difficult to select the amount and type of fluid for resuscitation. Due to rapid deterioration a single dose of methylprednisolone (MP) (SOOmg in 200ml saline iv over 20 minutes) was administered as a rescue medication. He had deferversence within 30 minutes, became conscious and alert in 1 hour, PR reduced to 96/minute, BP remained stable above 100/80mmHg and urine output increased to 0.8-1.4ml/Kg/Hr. His ECG became normal after 3 hours, and the echo cardiogram in 12 hours (EF-55%). CONCLUSIONS: This patient with dengue developed three episodes of severe haemodynamic compromise within 12 hours while having third space fluid accumulation, "myocardits" and altered level of consciousness making it difficult to institute fluid therapy. A single dose of MP given as rescue measure resulted in a dramatic recovery suggesting a beneficial effect of MP in sever dengue.by
