ABSTRACT
BACKGROUND: Despite the advent of modern neurosurgical techniques, new antibiotics, and modern imaging techniques, infection after ventriculoperitoneal (VP) shunt insertion and/or ventriculostomy is still a serious issue. AIM: The aim of this work was to study bacteriological profile and antimicrobial susceptibility pattern of cerebrospinal fluid shunt infections in infants and children. MATERIALS AND METHODS: A total of 90 patients under the age of 12 years undergoing cerebrospinal fluid shunt procedures were included. The CSF shunt fluid, external ventricular drain (EVD), shunt tube tip specimens were processed as per standard microbiological techniques. The organisms isolated were subjected to antimicrobial susceptibility using the Kirby-Bauer disk diffusion method. RESULTS: Of 20 infected patients 10 (50%) were culture positive. Most common organisms isolated were Acinetobacter baumannii 03 (30%) followed by Enterococcus faecalis 2 (20%). Two isolates of A. baumannii and one isolate of Klebsiella pneumoniae showed carbapenem resistance, which were sensitive to colistin. All Gram-positive isolates were sensitive to vancomycin and linezolid. Reinfection was found only in one (8.33%) patient. In 12 (60%) infected cases with shunt failure, revision of shunt was done. The shunt related mortality in this study was 1.11%. CONCLUSION: Most common organisms isolated were A. baumannii followed by E. faecalis. Carbapenem resistance was noted in these isolates which were sensitive to colistin. All Gram-positive isolates were sensitive to vancomycin and linezolid.
ABSTRACT
White piedra of scalp hair is considered a rare entity. We report three cases of this disorder all of whom presented with nodules on the hair. Potassium hydroxide preparations of the hair revealed clustered arthrospores and mature, easily detachable nodules. Cultures grew Trichosporon inkin in 2 patients and Trichosporon mucoides in one patient. Both these fungi are unusual causes of white piedra.
