RESUMO
Intracranial infections, especially subdural empyema, due to salmonella are rare. Subdural empyema caused by Salmonella paratyphi A has been documented only once earlier in the literature. Hence, we report a case of subdural empyema and osteomyelitis of cranial vault due to S. paratyphi A. A 42- year-old male presented with headache and purulent discharge from right parietal burr hole wound site. Patient gave a history of head injury two years ago. He underwent burr hole evacuation of chronic subdural haematoma, excision of outer membrane and right parietal craniectomy. The cultures grew S. paratyphi A. Recovery was uneventful following surgical intervention and antibiotic therapy.
RESUMO
This study was conducted to determine the frequency of different Candida spp. isolated from different parts of the hospital, associated risk factors and mortality rate. A total of 59 cases were selected for prospective analysis over a period of one and half years. Blood samples collected were processed by BACTEC (9240) method. Candidaemia was diagnosed by positive blood culture at least from two blood culture samples or from a clinically significant single blood culture sample. Candida spp. were identified by standard techniques. Most frequent isolates were C. tropicalis (35.6%), C. parapsilosis (28.8%), C. glabrata (11.9%) and C. pelliculosa (11.9%). Candida albicans was isolated only in 3.4% cases. Neonatology department accounted for highest number of isolates (27.1%), followed by gastrointestinal surgery (15.3%) and cardiac surgery (13.6%). Mortality was noted in 16.9%. Probable risk factors determined were intensive care unit stay (74.6%), antibiotic therapy (50.8%), central line (42.4%), urinary catheter (32.2%), ventilator (23.7%), malignancy (20.3%) and abdominal surgery (15.3%).
