A validated ultra-performance liquid chromatography mass spectrometric method (UPLC-MS/MS) was used for the simultaneous quantitation of candesartan (CN) and hydrochlorothiazide (HCT) in human plasma. The analysis was performed on UPLC-MS/MS system using turbo ion spray interface. Negative ions were measured in multiple reaction monitoring (MRM) mode. The analytes were extracted using a liquid-liquid extraction (LLE) method by using 0.1 mL of plasma volume. The lower limit of quantitation for CN and HCT was 1.00 ng/mL whereas the upper limit of quantitation was 499.15 ng/mL and 601.61 ng/mL for CN and HCT respectively. CN d4 and HCT-13Cd2 were used as the internal standards for CN and HCT respectively. The chromatography was achieved within 2.0 min run time using a C18 Pheno-menex, Gemini NX (100 mm ~ 4.6 mm, 5 mm) column with organic mixture:buffer solution (80:20, v/v) at a flow rate of 0.800 mL/min. The method has been successfully applied to establish the bioequivalence of candesartan cilexetil (CNC) and HCT immediate release tablets with reference product in human subjects.

Filariasis continues to be one of the endemic problemsworldwide with 40% of the cases in India. We report a caseof lymphatic filariasis in a 32-year old female who presentedwith a non-tender swelling over left upper arm. Bloodsample showed no eosinophilia while the FNAC wasdiagnostic of W. bancrofti. Patient responded well with oraldiethylcarbamazine. High index of suspicion of filariasis isindicated when dealing with a swelling of unknown causeespecially in filariasis endemic areas.

Introduction: To assess the incidence and causes of persistent thigh pain and peri-implant fractures after union in patients of intertrochanteric fractures treated with short cephalo-medullary nails.
Materials and methods: A retrospective observational study conducted at a Level 1 Trauma centre. A total of 122 patients of intertrochanteric fractures who were operated using short cephalo-medullary nails (170mm and 200mm lengths) between January 2018 to June 2019 were included in the study. Main outcomes measured were the incidence of thigh pain and peri-implant fractures.
Results: Out of the 122 patients with a mean follow-up of 14.1 month, 12 patients had persistent thigh pain. Six patients had the helical blade protruding from the lateral cortex, two of them had distal tip of nail abutting on the anterior cortex and four cases had prominent proximal segment of nail which may explain the cause of their pain. Five of these patients had a combination of these findings. Two patients had pain for which no other obvious cause was found. There were no cases of peri-implant fractures in our study.
Conclusion: Thigh pain associated with the use of short cephalon-medullary nails is often unrelated to nail length and can be prevented by using proper surgical technique. There seems to be no association between the use of short nails and peri-implant fractures.
