IntroductionExcessive perioperative bleeding requiring transfusion remains a potential complication of Total Knee Arthroplasty (TKA). There is overwhelming evidence supporting the efficacy of intravenous Tranexamic acid to reduce bleeding and the need for transfusion in TKA. There is still some question regarding the efficacy of other methods of Tranexamic acid administration. This case series study evaluated the effects of the use of intravenous Tranexamic acid administered alone, or in combination with intra-articular tranexamic acid on transfusion rate and other clinical outcomes; and compared this to a group of patients who received neither treatment.MethodWe conducted a case review of 150 patients who had undergone TKA from 2012-2015. 50 patients underwent TKA with IV Tranexamic acid (Group A). A further 50 patients underwent TKA with IV Tranexamic acid in combination with intra-articular administration of 2grams of Tranexamic acid in 20ml saline (Group B). A final 50 patients underwent TKA without the use of Tranexamic acid (non-treatment group). Outcome measures were transfusion rate, change in haemoglobin and haematocrit, medical review events, patient mortality and changes in knee flexion and extension measurements at six weeks after surgery.ResultsThere were no significant differences in red blood cell transfusion rates between the non-treatment group and the two treatment groups, however an absolute reduction in transfusion rate from 8% to 0% (p=0.134) was observed. The mean change of haemoglobin level in the non-treatment group was 29 while in treatment groups A and B, this was 23 and 19 respectively (p=0.0001). No significant difference was observed between treatment group A and B. There was a significant difference in post-operative haemoglobin level, where mean haemoglobin concentrations in non-treatment, Group A and B were 110 vs 115 vs 123 respectively (P= 0.0001). Pairwise comparison showed that Group B was significantly different when compared to both non treatment (p=0.0001) and treatment group A (p=0.020).  There were no significant differences observed in other outcomes.ConclusionThis study supports the existing literature and suggests that the use of IV Tranexamic acid alone or in combination with intra-articular dose in TKA may reduce the requirement for transfusion (Level IV evidence). Furthermore, this study suggests that the use of tranexamic acid as a combination of Intravenous and intra-articular administration has no effect on range of motion, or medical complications during hospital stay. Although it was not a statistically significant finding, our study suggested a trend towards a greater reduction in haemoglobin and haematocrit fall in the combination therapy group when compared to IV Tranexamic acid alone

Abstract Background To assess the efficacy and safety of intravenous and subsequent long-term oral tranexamic acid (TXA) following total knee arthroplasty (TKA) without a tourniquet. Methods In this double-blinded trial, 118 patients undergoing primary TKA were randomized into two groups: the patients in group A received intravenous TXA at 20-mg/kg 10 min before the surgery and 3 h postoperatively, and then oral 1 g TXA from postoperative day (POD) 1 to POD 14, and the patients in group B received intravenous TXA at 20-mg/kg 10 min before surgery and 3 h postoperatively, and then oral 1 g placebo from postoperative day (POD) 1 to POD 14. The primary outcome was total blood loss. Secondary outcomes included ecchymosis area and morbidity, postoperative transfusion, postoperative laboratory values, postoperative knee function and length of hospital stay. Complications, and patient satisfaction were also recorded. Results The mean total blood loss was lower in Group A than in Group B (671.7 ml vs 915.8 ml, P = 0.001). There was no significant difference in the transfusion rate between the two groups. Group A had a higher hemoglobin than Group B on POD 3 (106.0 g/L vs 99.7 g/L, P = 0.001). However, no significant difference was found for Hb or hematocrit on POD 1 or POD 14 between the two groups. Patients in Group A had less ecchymosis morbidity (7 vs 38, P = 0.001), smaller ecchymosis area (1.6 vs 3.0, P = 0.001) than Group B. The blood coagulation level as measured by fibrinolysis (D-Dimer) was lower in Group A than in Group B on POD 1 and POD 3 (4.6 mg/L vs. 8.4 mg/L, respectively, P = 0.001; 1.5 mg/L vs. 3.3 mg/L, respectively, P = 0.001). However, there was no significant difference on POD 14, and the fibrin degradation products showed the same trend. Patients in Group A had less swelling than those in Group B on POD 3 and POD 14. The circumference of the knee was 43.1 cm vs. 46.1 cm (POD 3, P = 0.001) and 41.4 cm vs. 44.9 cm (POD 14, P = 0.001) in Group A vs Group B, respectively. Nevertheless, the circumference of the knee in the two groups was similar on POD 1 and POD 3 M. No significant differences were identified in knee function, pain score, or hospital stay. No significant differences were identified in thromboembolic complications, infection, hematoma, wound healing and patients satisfaction between the two groups. Conclusion Intravenous and subsequent long-term oral TXA produced less blood loss and less swelling and ecchymosis compared with short-term TXA without increasing the risk of complications. Trial registration The trial was registered in the Chinese Clinical Trial Registry (ChiCTR-IPR-17012264).

Abstract Background We aimed to determine the efficacy and safety of multiple doses of intravenous tranexamic acid (IV-TXA) on perioperative blood loss in patients with rheumatoid arthritis (RA) who had undergone primary unilateral total knee arthroplasty (TKA). Methods For this single-center, single-blind randomized controlled clinical trial, 10 male and 87 female participants with RA, aged 50–75 years, who underwent unilateral primary TKA were recruited. The patients received one dose of 1 g IV-TXA 10 min before skin incision, followed by articular injection of 1.5 g tranexamic acid after cavity suture during the surgery. The patients were randomly assigned (1:1) into two groups and received an additional single dose of IV-TXA (1 g) for 3 h (group A) or three doses of IV-TXA (1 g) for 3, 6, and 12 h (group B) postoperatively. Primary outcomes were total blood loss (TBL), hidden blood loss (HBL), and maximum hemoglobin (Hb) level decrease. Secondary outcomes were transfusion rate and D-dimer levels. All parameters were measured postoperatively during inpatient hospital stay. Results The mean TBL, HBL, and maximum Hb level decrease in group B (506.1 ± 227.0 mL, 471.6 ± 224.0 mL, and 17.5 ± 7.7 g/L, respectively) were significantly lower than those in group A (608.8 ± 244.8 mL, P = 0.035; 574.0 ± 242.3 mL, P = 0.033; and 23.42 ± 9.2 g/L, P = 0.001, respectively). No episode of transfusion occurred. The D-dimer level was lower in group B than in group A on postoperative day 1 (P <  0.001), and the incidence of thromboembolic events was similar between the groups (P > 0.05). Conclusion In patients with RA, three doses of postoperative IV-TXA further facilitated HBL and Hb level decrease without increasing the incidence of adverse events in a short period after TKA. Trial registration The trial was registered in the Chinese Clinical Trial Registry (ChiCTR1900025013).

Abstract Objective The aim of this study was to compare tentorial incision (group A) versus retraction and tack up suture (group B) of the tentorial edge during the subtemporal approach for surgery in the high basilar region. Design 24 cadaveric dissections and 4 clinical cases of aneurysms of the high basilar region are presented. Assessment included visibility and operability afforded by either tentorial incision creating a dural flap (group A) or retraction of the tentorial edge and tethering with a suture (group B). Four patients, two with superior cerebellar artery aneurysms and two with proximal posterior cerebral artery aneurysms were treated with each approach. Results In the quantitative evaluations, we found no significant difference in the exposure of the posterior cerebral, superior cerebellar, and perforant arteries as well as surgical working area provided by either approach. However, tentorial incision allowed a significantly greater exposure of the basilar artery and the fourth cranial nerve (both p < 0.001). Concerning operability, tentorial incision provided no objective advantage for direct clipping of the high basilar region (groups A vs. B, p > 0.05). Subjectively, clipping of the high basilar segment was feasible using tentorial tethering only. Conclusion Retraction of the free edge of the tentorium downward by tethering with a suture is simple and fast method for exposure of aneurysms in the high basilar region when the pathology does not require a proximal control. In our data the rather more invasive and time consuming tentorial incision provided an additional objectified advantage only for placement of a proximal temporary clip.

Purpose. To compare the visual and surgical outcomes after a reuse or a replacement of a dislocated in-the-bag intraocular lens (IOL). Methods. This was a retrospective, nonrandomized case series at a single ophthalmological institution. Cases with an in-the-bag dislocation of an IOL were treated by pars plana vitrectomy and the reuse or the replacement of the IOL. The lens was held by intrascleral fixation of the haptics of the IOL under both conditions. The same dislocated IOL was reused in 6 eyes (group A) or it was replaced with another IOL in the other 9 eyes (group B). The pre- and postoperative parameters analyzed included the visual acuity, refractive error, corneal endothelial cell density, and intraocular pressure (IOP). Results. There was no significant difference between the two groups in the postoperative visual acuity (P=0.388), refractive error (P=0.955), IOP (P=0.529), and endothelial cell loss (P=0.940). A breakage or a tilting of the IOL was observed and required replacement in three eyes in the reuse group (P=0.044). Conclusions. Half of the cases with reused in-the-bag dislocated IOL had a breakage or a tilting of the IOL. The replacement of the in-the-bag dislocated IOL is better than the reuse of the IOL with intrascleral haptics fixation.

This experiment was conducted to determine the effect of papaya leaf (Carica papaya) and kalo jeera (Nigella sativa) seeds powdered supplementation in drinking water as a growth promoter in broiler chickens. A total of 20 Cobb-500 broiler chicks (day-old) were purchased from local hatchery (Nourish Poultry and Hatchery Ltd.) and after seven days of acclimatization chicks were randomly divided into two groups, A (n=10) and B (n=10). The group A was kept as a control and not treated. The group B was supplemented with papaya leaf and kalo jeera powder with feed and water. Weekly observations were recorded for live body weight gain up to 5th weeks and hematological tests were performed at 35th day’s age of broiler to search for hematological changes between control (A) and treatment (B) groups. The initial body weight of groups A and B on 1st were 41.00±0.56 gm and 41.50±0.35 gm, respectively and after 35th day of experiment final body weight were 1470±57.35 gm and 1720±58.56 gm, respectively and economics of production were analyzed and found that net profit per broiler was Tk. 8.91 and Tk. 20.69, respectively. The treatment group B was recorded statistically significant (at 1% level) increased (17.00%) for live body weight than that of control group A. The hematological parameters total erythrocyte count (TEC), erythrocyte sedimentation rate (ESR) and hemoglobin (Hb) estimation value of treatment group shows significant difference, while hemoglobin estimation does not show significant difference from control group. The results suggest that better growth performance could be achieved in broilers supplemented with papaya leaf and kalo jeera seeds.

Background: Despite the advances in the design and fixation of implants in total knee replacement (TKR). the amount of postoperative bleeding is still an important issue that has not been resolved. This study aimed to measure the effectiveness of various tranexamic acid administration. Methods: This was a randomized controlled trial study, held from August 2014 to February 2016 at Cipto Mangunkusumo Hospital, Jakarta. Twenty two patients having TKR were divided into three groups: the control group, the tranexamic acid intra-articular-intraoperative group, and the intravenous preoperative group. Intraoperative bleeding, haemoglobin (Hb) level on preoperative to five-day-post-surgery, total drain production, total blood tranfusion needed and the drain removal timing were recorded and compared. Numerical data were analyzed by using parametric and non-parametric test, depended on the normality of the data. Results: The amount of blood transfusion needed in both the intra-articular group (200±SD 100 mL) and the intravenous group (238±SD 53 mL) were significantly different compared to those in the control group (1,016±SD 308.2 mL) (p=0.001). Meanwhile, there was no significant difference between the amount of blood transfusion needed in the intra-articular group and the intravenous group. Total drain production in the intra-articular group (328±SD 193 mL) and intravenous group (391±SD 185 mL) was significantly different compared to the control group (652±SD 150 mL) (p=0.003). No significant difference between the levels of both preoperative and postoperative haemoglobin, the amount of intraoperative bleeding, and the duration of drain usage. Conclusion: Intravenous and intra-articular tranexamic acid effectively decreased transfusion volume and drain production in patients undergoing TKR.

The aim of this study was to determine the effect of tocopherol and selenium on the performance of buserelin (GnRH analogue) for estrus induction in anestrus mares. A total of 18 seasonally anestrus mares were divided into three equal groups (n=6 in each) after ovarian scanning. Mares in group A (treatment group) were treated with tocopherol and selenium intramuscularly along with daily dose of buserelin. Mares which came into heat within ten-day buserelin protocol, further injections of buserelin for those mares were stopped. Mares in group B were treated with buserelin intramuscularly only for ten days. Mares which came into heat within ten-day buserelin protocol, further injections of buserelin were stopped. Blood/serum was collected from each experimental mare kept in different groups (A-C) at days 1, 11, 12, 13 and 14. Onset of estrus signs was 83.3, 33.3 and 0% in group A, B and C, respectively, that was significant (P<0.05) among groups. Follicular dynamics were 20.24±3.00, 14.59±2.24 and 10.35±0.63mm in groups A, B and C, respectively with significant (P˂0.05) difference. Change in serum E2 contents was significantly (P˂0.05) different among groups A, B and C whereas progesterone concentration showed non-significant difference among groups.

Purpose: To evaluate the characteristics of peripheral anterior chamber measurements by Pentacam after posterior implantable collamer lenses (ICL) and toric ICL (TICL) with central hole (V4c) implantation.Methods: Prospective, non-randomized consecutive case series. Forty-six patients undergoing ICL implantation in one eye (Group A) and identically sized TICL in the contralateral eye (Group B) in the Refractive Surgery Center of Eye and ENT Hospital of Fudan University were prospectively included. According to ICL/TICL size, these eyes were further divided into four subgroups. Peripheral anterior chamber depth (PACD) and angle (ACA) in nasal and temporal sides were measured using Pentacam pre-operatively and 12-month post-operatively.Results: The safety indices were 1.34 ± 0.32 and 1.25 ± 0.16 and the efficacy indices were 1.20 ± 0.24 and 1.19 ± 0.19 for ICL and TICL groups, respectively. There was no significant difference in pre-operative PACD or ACA between the two groups. Post-operative PACD and ACA were significantly lower than pre-operative values. Variations of PACD and ACA of TICL group were significantly larger than those of ICL group. The change of ACA for 13.2 mm lenses was significantly larger than that of 12.6 mm lenses. Pre-operative CACD and vault were significantly associated with post-operative PACD, while pre-operative ACA and vault were significantly associated with post-operative ACA.Conclusions: Variations of PACD and ACA were greater in eyes after TICL (V4c) implantation compared with identically sized ICL (V4c) implantation and with larger size than smaller size lens implantation. Pre-operative anterior chamber structure and vault affect post-operative PACD and ACA.

ABSTRACT Aim To study the efficacy of topical intraarticular vs intravenous tranexamic acid (TXA) in reducing blood loss following primary total knee replacement (TKR). Materials and methods A phase 3, single center, double blind and randomized controlled study was conducted in the Department of Orthopedics, Sri Ramachandra University, Chennai, Tamil Nadu. A prospective study of 100 patients lasted from July 2013 to July 2015. Results Postoperative transfusion rates were zero in both the groups (intraarticular and intravenous). The mean 48-hour drain collected is 285.6 ml in group A (intraarticular), while it is 325.8 ml in group B (intravenous); the mean drop in hemoglobin is 1.7 gm/dl in group A (intraarticular) while it is 2.4 gm/dl in group B (intravenous). Conclusion This study shows that topical intraarticular administration of TXA has better efficacy than intravenous TXA in controlling postoperative blood loss following primary uncomplicated TKR with no significant complications.
