Levofloxacin induced psychosis: a rare case report

Levofloxacin is a commonly prescribed antibiotic for treating bacterial infections in routine clinical practice. A wide range of side-effects have been ascribed to the quinolone group of drugs, the most common being gastrointestinal. Central nervous system is rarely involved; neuropsychiartic complications are among the least reported adverse reactions. We report a rare case of levofloxacin induced acute psychosis in a young male presenting in out-patient department with signs of urinary tract infection along with pneumonitis

A simple planning technique of craniospinal irradiation in the eclipse treatment planning system

A new planning method for Craniospinal Irradiation by Eclipse treatment planning system using Field alignment, Field-in-Field technique was developed. Advantage of this planning method was also studied retrospectively for previously treated five patients of medulloblastoma with variable spine length. Plan consists of half beam blocked parallel opposed cranium, and a single posterior cervicospine field was created by sharing the same isocenter, which obviates divergence matching. Further, a single symmetrical field was created to treat remaining Lumbosacral spine. Matching between a inferior diverging edge of cervicospine field and superior diverging edge of a Lumbosacral field was done using the field alignment option. ′Field alignment′ is specific option in the Eclipse Treatment Planning System, which automatically matches the field edge divergence as per field alignment rule. Multiple segments were applied in both the spine field to manage with hot and cold spots created by varying depth of spinal cord. Plan becomes fully computerized using this field alignment option and multiple segments. Plan evaluation and calculated mean modified Homogeneity Index (1.04 and 0.1) ensured that dose to target volume is homogeneous and critical organ doses were within tolerance. Dose variation at the spinal field junction was verified using ionization chamber array (I′MatriXX) for matched, overlapped and gap junction spine fields; the delivered dose distribution confirmed the ideal clinical match, over exposure and under exposure at the junction, respectively. This method is simple to plan, executable in Record and Verify mode and can be adopted for various length of spinal cord with only two isocenter in shorter treatment time

Multiple metastases from ovarian cancer

Epithelial ovarian cancer is one of the most common ovarian tumours. Ovarian cancer affects women in the age group >60 years much more frequently than younger women. At the time of diagnosis, cancer will already have spread beyond the ovaries in approximately 75% of cases. We report a case of epithelial ovarian cancer presenting with liver and thoracic vertebral metastases 4 months after completion of treatment, as part of distant spread. The patient was then treated with gemcitabine-based chemotherapy. Palliative radiotherapy was given for the involved spine

Evaluation of Uncertainty of Measurement in Calibration of Electrostatic Voltmeter —A Case Study

Various sources of the uncertainty in measurement and their estimation based on Type A and Type B method as per ISO/IEC 17025 guidelines are also discussed. The result s are reported at k = 2 for approx. 95 per cent confidence level. The standards used for calibration are traceable to the ‘National Standards’.</span
