A Novel Data Generation Approach for Digital Forensic Application in Data Mining
With the rapid advancements in information and communication technology in the world, crimes committed are also becoming technically intensive. When crimes committed use digital devices, forensic examiners have to adopt practical frameworks and methods for recovering data for analysis as evidence. Data Generation, Data Warehousing and Data Mining, are the three essential features involved in this process. This paper proposes a unique way of generating, storing and analyzing data, retrieved from digital devices which pose as evidence in forensic analysis. A statistical approach is used in validating the reliability of the pre-processed data. This work proposes a practical framework for digital forensics on flash drives
The incidence of postoperative meningitis in neurosurgery: An institutional experience
Introduction : Meningitis is the most dreaded cause of morbidity and
mortality in neurosurgical patients. The reported incidence of
postoperative meningitis is quite varied 0.5-8%. Material and Methods
: The study cohort included all the patients who underwent neurosurgery
at the department of neurosurgery, National Institute of Mental Health
and Neurological Sciences, Bangalore, India over a period of seven
years (2001 - 2007). Patients with culture positive meningitis were
included for analysis. The incidence of postoperative meningitis was
analyzed depending on the type of surgery performed and the
microbiological profile of the organisms, and their sensitivity
pattern. Results : Of the 18,092 patients who underwent neurosurgical
procedures during the study period, 415 patients developed infection.
The overall incidence of meningitis was 2.2%. The incidence of
meningitis was high (7.7%) in patients who had a pre-existing infection
like post-pyogenic meningitis or tuberculosis hydrocephalus. The
procedure mainly performed in this subgroup was shunt. The most common
organisms causing meningitis were non-lactose fermenting Gram-negative
bacillus followed by Pseudomonas and Klebsiella species. The
methicillin-resistant Staphylococcus aureus strains were isolated in
2.6% of the patients. Ninety-one strains were multi-drug resistant,
among which four strains were resistant to all antibiotics tested. The
overall mortality in patients with meningitis was 5%. Conclusion :
Meningitis remains one of the most dreaded complications of
neurosurgical procedures and is common in patients with preexisting
infection. Gram-negative organisms are the most common causative
pathogens of postoperative meningitis
