Journal of clinical neuroscience : official journal of the Neurosurgical Society of Australasia. 2023;110:53-60
Abstract
Tranexamic Acid (TXA) has been used in medical and surgical practice to reduce haemorrhage. The aim of this review was to evaluate the effect of TXA use on intraoperative and postoperative outcomes of meningioma surgery. A systematic review and meta-analysis was conducted in accordance with the PRISMA statement and registered in PROSPERO (CRD42021292157). Six databases were searched up to November 2021 for phase 2-4 control trials or cohort studies, in the English language, examining TXA use during meningioma surgery. Studies ran outside of dedicated neurosurgical departments or centres were excluded. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Random effects meta-analysis were performed to delineate differences in operative and postoperative outcomes. Four studies (281 patients) were included. TXA use significantly reduced intraoperative blood loss (mean difference 315.7 mls [95% confidence interval [CI] -532.8, -98.5]). Factors not affected by TXA use were transfusion requirement (odds ratio = 0.52; 95% CI 0.27, 0.98), operation time (mean difference = -0.2 h; 95% CI -0.8, 0.4), postoperative seizures (Odds Ratio [OR] = 0.88; 95% CI 0.31, 2.53), hospital stay (mean difference = -1.2; 95% CI -3.4, 0.9) and disability after surgery (OR = 0.50; 95% CI 0.23, 1.06). The key limitations of this review were the small sample size, limited data for secondary outcomes and a lack of standardised method for measuring blood loss. TXA use reduces blood loss in meningioma surgery, but not transfusion requirement or postoperative complications. Larger trials are required to investigate the impact of TXA on patient-reported postoperative outcomes.

Cureus. 2023;15(3):e36230
Abstract
Background Total hip arthroplasty (THA) is the most successful orthopedic elective surgical procedure for end-stage hip arthritis. THA is linked with significant blood loss, ranging from 1,188 to 1,651 mL, and a transfusion rate of 16-37%, which frequently results in postoperative blood transfusions. Postoperative blood transfusions can be avoided by using autologous blood transfusion, intraoperative blood saving, local anesthetic, hypotensive anesthesia, and antifibrinolytic medications such as tranexamic acid (TXA) administration. Methodology A double-blinded, placebo-controlled, randomized, controlled study was conducted with three prospective groups to investigate the efficacy of topical and systemic routes of a single intraoperative dose (1.5 g) of TXA. Patients were recruited from our center between October 2021 to March 2022 who were undergoing primary total hip replacement. Estimated blood loss was calculated and compared in groups, and a p-value of <0.05 was taken as significant. Results A total of 60 patients were recruited in our study. Estimated blood loss was similar in both treatment groups, 816.8 ± 219.9 mL in the systemic TXA group and 775.5 ± 107.2 mL in the topical TXA group. The placebo group had 1,066.3 ± 150.4 mL estimated blood loss, which was significantly higher compared to the treatment groups. Conclusions Administration of TXA (1.5 g) significantly lowers blood loss without increasing problems, which can eliminate concerns about intravenous TXA use. TXA reduces blood loss by 270 mL on average.

Journal of experimental orthopaedics. 2022;9(1):42
Abstract
PURPOSE A tourniquet is routinely used during total knee arthroplasty (TKA) to reduce intra-operative hemorrhage, though surgery without a tourniquet is becoming popular. To address concerns about the effect of blood at cement interfaces on long-term implant stability, we conducted a systematic review among patients undergoing total knee arthroplasty to determine if TKA with a tourniquet, compared to TKA without a tourniquet or with reduced tourniquet duration, is associated with better mid-term and long-term implant stability. METHODS A literature search was conducted without language restriction in PubMed, Cochrane database and Web of Science from conception to 17th March, 2021. Prospective cohorts, randomized and observational, that compared tourniquet use with a control group, followed patients for 3 months or more and reported outcomes concerning implant stability, limb function, pain and inflammation. Article selection, quality assessment according to the Revised Cochrane risk assessment scale and Newcastle Ottawa Scale, and data extraction were conducted in duplicate. PROSPERO CRD42020179020. RESULTS The search yielded 4868 articles, from which 16 randomized controlled trials (RCT) and four prospective cohort studies, evaluating outcomes of 1884 knees, were included. Eleven RCTs were evaluated to be low overall risk of bias, five RCTs had some concerns and four cohort studies were good quality. Few studies showed benefits of tourniquet use in mid-term implant stability (1/6), pain (1/11) and limb inflammation (1/5), and long-term implant stability (1/1). One study reported a significantly improved range of motion (1/14) while another reported significantly reduced quadriceps strength (1/6) in the tourniquet group. The remaining studies reported non-significant effect of tourniquet use. CONCLUSION Although few studies indicated benefits of tourniquet use in mid-term pain, limb inflammation, implant loosening and function, and long-term implant loosening, the majority of studies report no significant advantage of tourniquet use in total knee arthroplasty.

Cureus. 2022;14(3):e23017
Abstract
AIMS AND OBJECTIVES To measure the additional effect of platelet-rich plasma (PRP) on functional outcome of anterior cruciate ligament tear managed by augmenting anterior cruciate ligament (ACL) reconstruction with PRP. METHODS The present study was conducted on patients with ACL tear admitted in the department of orthopaedics, King George's Medical University, Lucknow wherein a total of 70 subjects were assigned into two groups of 35 patients each randomly, viz Group 1 in which the patients were treated by quadruple hamstring graft alone and Group 2 in which the patients were treated with augmented hamstring graft with PRP. The standardized anterior drawer test, Lachman's test, Lysholm knee score were quantified both preoperatively and postoperatively at different follow-ups and also tibial tunnel widening was measured postoperatively at different follow-ups. RESULT The present study had 70 patients with ACL tears. The mean age of patients in non-PRP groups was 29.71 ±2.99 years while that in the PRP group was 28.34±4.32 years. On comparing the improvement in grades at pre-op, immediate postop, 6 weeks, and 3 months follow-ups, there was no statistically significant difference between the two groups. The tibial tunnel widening also showed no significant difference between the two groups. CONCLUSION In our study, it was found that both the groups showed improvements in grades of anterior drawer test and Lachman's test postoperatively but the difference between both the groups was not significant. Similarly, while comparing the improvements in Lysholm knee score and tibial tunnel widening among both the groups, the difference was not significant. Follow up of 3 months was a limiting factor in our study. This technique needs further clinical evaluation to assess the long-term results.

Medicine and pharmacy reports. 2021;94(2):220-228
Abstract
BACKGROUND Periodontal disease is one of the major causes of alveolar bone loss. There are various ways of regenerating the lost bone, i.e. guided tissue regeneration, bone grafts, and growth factors. In this purview, it becomes immensely important for a clinician to decide the best modality of treatment. In this study, we compared the effect of demineralized freeze-dried bone allograft (DFDBA) in combination with concentrated growth factors (CGF) verses CGF alone. METHODS This double-blind, split-mouth study was conducted on ten patients with two comparable bilateral intrabony defects. Each pair of defects was randomly treated by DFDBA + CGF or CGF alone. Clinical parameters such as plaque index (PI), modified gingival index (MGI), pocket probing depth (PPD), and relative attachment level (RAL) were recorded at baseline, three months, and six months. In addition, radiograph with grids was also taken at baseline and six months. The paired t-test was used to compare the pre- and post-treatment values and the unpaired t-test was used to compare the test and control group. RESULTS The PI score decreased significantly from baseline to six months. Similarly, the mean MGI score decreased significantly from baseline to six months. The intragroup comparison showed that there was a significant reduction in PPD in both the test and control group. However, the intergroup comparison showed that the reduced pocket depth was not significant. The intragroup radiographic comparison showed that there was the significant formation of bone in both the test and control group but inter-group showed that the formation of bone among both the group were non-significant. CONCLUSION Radiographic and clinical outcomes of this study concluded that post six months, both groups demonstrated significant improvement in clinical and radiographic parameters. However, the addition of DFDBA to CGFs did not give any additional benefits.

Dutt UK, Kumar S, Dorairajan LN, Badhe BA, Manikandan R, Singh S
Urology annals. 2021;13(3):199-204
Abstract
OBJECTIVE Transurethral resection of the prostate (TURP) is a common procedure for the treatment of benign prostatic hyperplasia (BPH). Previous studies on the effect of 5-alpha reductase inhibitors on perioperative blood loss in TURP and microvessel density (MVD) in the prostate are equivocal. We evaluated whether pretreatment with finasteride for 2 weeks before surgery can reduce perioperative blood loss in TURP and MVD in the prostate. MATERIALS AND METHODS Sixty-eight patients of BPH planned for TURP were randomized into two groups. The study group comprising 34 patients was treated with finasteride (5 mg/day) for 2 weeks and the placebo group comprising 34 patients received placebo for 2 weeks, before TURP. Blood loss was measured in terms of a reduction in the blood hemoglobin (Hb) and hematocrit (HCT) levels between preoperative values and 24 h after surgery. MVD was measured in the resected prostate tissue stained with anti-CD31 monoclonal antibody. RESULTS The reduction of Hb and HCT in the finasteride group was significantly lower than the reduction in the placebo group (P < 0.05). The artery (P = 0.005), vein (P = 0.05), and gland (P = 0.008) densities were significantly less in the finasteride group than in the placebo group. There was no significant correlation between blood loss and MVD. CONCLUSIONS Our study suggests a clear advantage of the preoperative use of finasteride for 2 weeks by reducing the perioperative blood loss in TURP in patients with BPH. While there is a significant reduction in MVD in the prostate on treatment with finasteride, it is not clear that this is the mechanism of reduction in blood loss in TURP.

Thetay AA, Kumar S, Irfan M, Lund RG, Desai K, Hirani T, Sevak J
Medicine and pharmacy reports. 2021;94(4):471-476
Abstract
BACKGROUND Platelet Rich Fibrin (PRF) is a concentrate of leucocyte and platelets that contains various polypeptide growth factors. It has immense potential for use as a periodontal regenerative material in periodontal defects. Porous hydroxyapatite (HA) has long been used as bone grafting material. Recently it has been reported that when PRF is used in combination with HA, itgives a synergistic effect and results in a better periodontal regeneration. The present study aims to explore the clinical and radiographic effectiveness of autologous PRF versus PRF+HA in the regenerative treatment of intrabony defects (IBD) in patients with chronic periodontitis. METHODS Sixty patients with IBDs were divided into test and control groups. The test group patients were treated with autologous PRF, whereas the control group patients were treated with PRF+HA. Clinical parameters were recorded at baseline, three months, six months and nine months' time interval. Radiographic measurements were recorded at baseline and nine months. RESULTS A reduction in PI, MGI, PPD, RAL, and IBD was observed in both the groups at nine months. Mean IBD reduction in the control group was 3.70 ± 1.16 mm, whereas, the mean reduction in the test group was 4.80 ± 1.03 mm, showing a significant reduction in IBDs. Similarly, the percentage of bone fill in the test group was 65% ± 3.67%, whereas bone fill in controls was 56.7% ± 3.56%, showing a significant bone fill in the study group. CONCLUSION Treatment of IBDs with PRF+HA showed a significant improvement in all the clinical and radiographic parameters. When HA was added to PRF, it increased the regenerative effect in the treatment of 3 wall IBDs.

Does tranexamic acid improve intra-operative visualisation in endoscopic ear surgery? A double-blind, randomised, controlled trial
Das A, Mitra S, Ghosh D, Kumar S, Sengupta A
The Journal of laryngology and otology. 2019;:1-5
Abstract
OBJECTIVE To assess the effect of tranexamic acid on intra-operative bleeding and surgical field visualisation. METHODS Fifty patients undergoing various endoscopic ear surgical procedures, including endoscopic tympanoplasty, endoscopic atticotomy or mastoidectomy, endoscopic ossiculoplasty, and endoscopic stapedotomy, were randomly assigned to: a study group that received tranexamic acid or a control group which received normal saline. The intra-operative bleeding and operative field visualisation was graded using the Das and Mitra endoscopic ear surgery bleeding and field visibility score, which was separately analysed for the external auditory canal and the middle ear. RESULTS The Das and Mitra score was better (p < 0.05) in the group that received tranexamic acid as a haemostat when working in the external auditory canal; with respect to the middle ear, no statistically significant difference was found between the two agents. Mean values for mean arterial pressure, heart rate and surgical time were comparable in both groups, with no statistically significant differences. CONCLUSION Tranexamic acid appears to be an effective haemostat in endoscopic ear surgery, thus improving surgical field visualisation, especially during manipulation of the external auditory canal soft tissues.

Kumar S, Singh S, Singh P, Singh SK
Central European Journal of Urology. 2016;69((2)):190-7.
Abstract
INTRODUCTION To compare the outcomes of tubeless day care PNL using hemostatic seal in the access tract versus standard PNL. MATERIAL AND METHODS It was a prospective randomized controlled study. Cases were randomized to either the day care group with hemostatic seal (DCS) or the control group where patients were admitted and a nephrostomy tube was placed at the conclusion of surgery. RESULTS A total of 180 cases were screened and out of these, 113 were included in the final analysis. The stone clearance rates were comparable in both the groups. The mean drop in hemoglobin was significantly lower in DCS group than the control group (1.05 +/-0.68 vs. 1.30 +/-0.58 gm/dl, p = 0.038).Mean postoperative pain score, analgesic requirement (paracetamol) and duration of hospital stay were also significantly lower in the DCS group (3.79 +/-1.23 vs. 6.12 +/-0.96, 1.48 +/-0.50 vs. 4.09 +/-1.11 grams and 0.48 +/-0.26 vs. 4.74 +/-1.53 days respectively; p <0.05). The incidence of urine leakage through the access tract site was significantly lower in the DCS subgroup when compared to the controls (3.6% vs. 21.1%, p <0.05). Cases in the DCS group resumed their normal activities in a significantly shorter time (8.05 +/-3.05 vs.18.42 +/-4.42 days; p <0.05). Higher proportion of cases in the DCS group got re-admitted, although it was not a statistically significant number (7.1% vs. 1.8%; p = 0.21). CONCLUSIONS Tubeless day care PNL with composite hemostatic tract seal is considered safe. It resulted in a significant reduction of blood loss and analgesic requirement with significantly reduced hospital stay, nephrostomy tube site morbidity and time required to resume normal activity when compared to the standard PNL. However, patients must be compliant with the given instructions and should have access to a health care facility, as few of them may need re-admission.

Dhiman M, Kumar S, Duhan J, Sangwan P, Tewari S
Journal of Endodontics. 2015;41((7)):985-91.
Abstract
INTRODUCTION The purpose of this prospective, randomized controlled trial was to evaluate the healing outcomes of platelet-rich fibrin (PRF) in periapical surgeries involving apicomarginal defects and to compare these results with surgeries not using any guided tissue regeneration techniques. METHODS Thirty patients with suppurative chronic apical periodontitis and apicomarginal communication were randomly assigned to either the PRF or the control group. Clinical and radiographic parameters including pocket depth (PD), clinical attachment level, gingival marginal position, size of periapical lesion, and percentage reduction of the periapical radiolucency were recorded at baseline and at an interval of 3 months for a period of 12 months. RESULTS The overall success rate was 83.33%, with a success rate of 86.66% (13 of 15 teeth) for PRF group and 80% (12 of 15 teeth) for control group. Both the groups exhibited a significant reduction in PD, clinical attachment level, gingival marginal position, and size of periapical lesion at 12-month period. No significant differences were observed between the 2 groups for these parameters except PD, which showed a statistically significant reduction in the PRF group (P < .05). CONCLUSIONS The adjunctive use of regenerative techniques may not promote healing of apicomarginal defects of endodontic origin.Copyright © 2015 American Association of Endodontists.
