Background: The introduction of MALDI-TOF MS, BD PHOENIX, and VITEK-2
equipment into the clinical microbiology laboratory has changed the techniques of
fungal identification. This technique can be used to find cryptic species that have
critical susceptibility patterns. The MALDI-TOF MS, BD PHOENIX, and VITEK-2
systems were used to identify clinical strains. Assuming MALDI-TOF MS isolate
identification as standard, discrepancies between three approaches were evaluated.
Finally, these isolates were subjected to in vitro susceptibility testing.
Results: The agreement between the two approaches for 498 yeast isolates was 93.6
percent (32 discrepant isolates). The BD PHOENIXconcordance with VITEK-2 systems
was lower than MALDI-TOF MS. Several of these discordant yeasts had high
antifungal agent MICs.
Conclusions: We discovered the unusual yeasts, including Candida auris, Trichosporon
faecalis and other yeasts. Although not totally satisfying, the performance of the BD
Phoenix system was superior to that of the Vitek 2 system, particularly its performance
with yeast species that are infrequently isolated in the clinical context. Although new
and promising molecular methods such as MALDI-TOF MS are now available, many
clinical microbiology laboratories continue to rely on instruments such as the BD
Phoenix and Vitek 2 for routine identification of fungal agents.

Laparoscopy has revolutionised surgery and management of the patient with marked decrease in morbidity and post-operative complications. Initially, these procedures were done using only General Anaesthesia. However, now with the introduction of Spinal anaesthesia and after learning its advantages, surgeons are slowly beginning to gravitate towards this mode of anaesthesia. Sixty three patients who were admitted in the hospital for appendicitis participated in this Randomized controlled trial conducted in a tertiary care hospital in India. Thirty three patients were randomly included in Group A (undergoing laparoscopic surgery under Spinal Anaesthesia) and thirty patients in Group B (undergoing laparoscopic surgery under General Anaesthesia). The mean values of Systolic and diastolic pressure was found to be significantly higher in patients who were administered General anaesthesia and no change in the respiratory functions was observed following administration of either Spinal or General anaesthesia. Laparoscopic surgery under Spinal anaesthesia is a viable and safe alternative as compared to General anaesthesia. The recovery rates and the satisfaction reported by patients is also better. Spinal anaesthesia also helps in maintaining better haemodynamic stabilization.
