Comparison of Modified Frailty Index, Clinical Frailty Scale, ECOG Score, and ASA PS Score in Predicting Postoperative Outcomes in Cancer Surgery: A Prospective Study.

Multiple pre-operative risk assessment scores are available for risk stratification of cancer patients undergoing surgery. This is the first study comparing commonly used preoperative risk assessment tools of Eastern Cooperative Oncology Group Performance Scale (ECOG) and American Society of Anaesthesiologists Physical Status Scale (ASA PS) with frailty scores of Modified Frailty Index (MFI) and Clinical Frailty Scale (CFS). This is a prospective observational study of adult cancer patients undergoing oncosurgery in a tertiary cancer center over one year.

Sentinel Node Biopsy in Post-neoadjuvant Chemotherapy Breast Cancer Patients Using Pre-chemotherapy Breast Tattooing.

The role of sentinel lymph node biopsy (SLNB) in locally advanced breast cancer (LABC) post-neoadjuvant chemotherapy (NACT) is debatable. We conducted a novel pilot study in which pre-NACT tattooing of breast lumps in LABC patients resulted in black tattoos being deposited in the axillary node. We hypothesized that this black node was the sentinel node.

Pseudopyronine B: A Potent Antimicrobial and Anticancer Molecule Isolated from a Pseudomonas mosselii.

In continuation of our search for new bioactive compounds from soil microbes, a fluorescent Pseudomonas strain isolated from paddy field soil of Kuttanad, Kerala, India was screened for the production of bioactive secondary metabolites. This strain was identified as Pseudomonas mosselii through 16S rDNA gene sequencing followed by BLAST analysis and the bioactive metabolites produced were purified by column chromatography (silica gel) and a pure bioactive secondary metabolite was isolated. This bioactive compound was identified as Pseudopyronine B by NMR and HR-ESI-MS.

Nonconvulsive status epilepticus: An unusual cause of postoperative unresponsiveness following general anaesthesia.

Any altered behaviour or sensorium following general anaesthesia is of concern to the anaesthesiologist, as it could be attributed to the anaesthetic itself or to a hypoxic insult, both of which can have medicolegal implications. It is important to be aware of a relatively unfamiliar entity known as nonconvulsive status epilepticus in this context. We report two cases to highlight this condition.
