ABSTRACT
Methods@#The study included 60 patients graded American Society of Anesthesiologists I and II and scheduled for thoracolumbar spine surgery involving >3 vertebral levels. The patients were divided into two groups: group KD (ketodex) and group F (fentanyl). The primary objective was to compare the postoperative analgesic requirements among the groups. The secondary objectives included a comparison of the intraoperative anesthetic requirements, postoperative pain scores, hemodynamic parameters, side effects of the study drugs, and the duration of post-anesthesia care unit stay of both the groups. @*Results@#Ketodex use prolonged the mean time to first rescue analgesia (22.00±2.30 hours vs. 11.69±3.02 hours, p 0.05). The postoperative pain scores were significantly lower in the group KD than in group F at most timepoints (p 3 vertebral levels to achieve prolonged analgesia without any opioidrelated side effects.
ABSTRACT
Introduction: Silver diamine fluoride (SDF) is employed as an adjunct cariostatic agent in the management of dental caries in high-risk population. Other than fluorides, chlorhexidine (CHX) is the most potent antimicrobial and efficacious agent against Streptococcus mutans. Aim: The aim of this study is to evaluate and differentiate the efficacy of 38% silver diamine fluoride, CHX varnish, and fluoride varnish on carious primary teeth. Materials and Methods: Ninety children having a count of ?1 carious lesion were recruited. Thirty-eighty percent silver diamine fluoride or fluoride varnish and CHX varnish were topically applied on the lesion. The primary outcome measured was the arrest of carious lesion (lesion rendered inactive as per the Nyvad criteria) after a follow-up of 14–21 days. Dental biofilm sample was obtained from each child and subsequently assessed for microbial composition by colony-forming unit method before and after treatment followed by protein analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis method. Results: Average proportion of arrested caries lesions in the SDF group was higher followed by CHX and fluoride varnish groups. Decreased total protein amount was found in SDF group. This proves that there is decrease in microbial load posttreatment in SDF group. Conclusion: Thirty-eight percent SDF is more effective than CHX varnish and fluoride varnish in arresting dentin carious lesions in young children.
ABSTRACT
PURPOSE: Restoring the native patellar thickness after patellar resurfacing provides optimal function of the knee after arthroplasty and minimises complications related to the patellofemoral articulation. The aim of this study was to assess the usefulness of a thin patellar button (6.2 mm) in patients with a patella thickness of less than 20 mm during total knee arthroplasty. MATERIALS AND METHODS: This is a retrospective case control study. A total of 54 female patients with an intraoperative patellar thickness of < 20 mm, resurfaced with a patellar button of 6.2 mm in thickness were identified (group 1). They were matched with 54 patients with a patellar thickness of 20–23 mm, resurfaced with a patellar button of 8 mm (group 2), based on age, sex, body mass index, and deformity. A clinical and radiological evaluation was done at a minimum 2-year follow-up. RESULTS: The preoperative mean patellar thickness was 18.94±1.07 mm and was restored to 19.06±0.79 mm in group 1, as compared to 21.63±0.99 mm and 21.72±0.99 mm in group 2. The mean postoperative range of motion was 122.22°±9.25° in group 1 and 123.52°±8.72° in group 2 (p=0.13). No patellar bone or button related complications were observed in any patient in either group. CONCLUSIONS: The 6.2 mm thin patella is useful to restore the native thickness in patients with a patellar thickness of less than 20 mm without risk of button fracture, loosening or overstuffing.

PURPOSE: Simultaneous bilateral total knee arthroplasty (TKA) is associated with excessive blood loss and morbidity arising from postoperative reduction in hemoglobin (Hb). The purpose of this prospective randomized study was to determine if drains have any effect on blood loss, postoperative reduction in Hb levels and transfusion rates compared to no drainage in simultaneous bilateral TKAs. MATERIALS AND METHODS: Two hundred and thirty patients who underwent simultaneous bilateral TKA by a single surgeon were randomly allotted to drain or no-drain group (n=115 in each group). Postoperative Hb level, blood loss volume and transfusion rate were compared between the two groups. RESULTS: The mean postoperative Hb level (p=0.38), blood loss volume (p=0.33) and transfusion rate (p=0.52) in the drain group were not significantly different compared to the no-drain group. No statistical difference was found in terms of complications, readmissions and mortality rates between the two groups. CONCLUSIONS: No significant difference was observed in the two groups with respect to blood loss and blood transfusion. Non-drainage does not offer an advantage over drainage with respect to conserving blood in simultaneous bilateral TKA.
