PURPOSE: The purpose of this study is to evaluate the incidence and treatment of recurrent hemarthrosis after total knee replacement (TKR). MATERIALS AND METHODS: Among a total of 5,510 patients who underwent TKR from March 2000 to October 2016, patients who had two or more bleeding 2 weeks after surgery were studied. Conservative treatments were performed for all cases with symptoms. In patients who did not respond to conservative treatment several times, embolization was performed. We retrospectively evaluated the postoperative bleeding time, bleeding frequency, treatment method, and outcome. RESULTS: Seventeen (0.3%) of the 5,510 patients developed recurrent hemarthrosis. Bleeding occurred at an average of 2 years 3 months after the operation. Joint aspiration was performed 3.5 times (range, 2 to 10 times) on average, and 14 cases (82.3%) were treated with conservative treatment. In 3 patients with severe bleeding and hemorrhage, embolization was performed. CONCLUSIONS: Recurrent hemarthrosis after TKR is a rare disease with a low incidence of 0.3% and usually could be treated by conservative treatment. If recurrences occur repeatedly, embolization through angiography or surgical treatment may be considered, but the results are not satisfactory and careful selection of treatment modalities is warranted.

The postoperative analgesic effects of firocoxib in ovariohysterectomized cats were observed. Twenty-four cats were divided into 3 groups: control (no medicine), firocoxib-1 (1 mg/kg/day) and firocoxib-3 (3 mg/kg/day). Colorado pain scale scores (CPSS), composite pain scores (CPS), and buccal mucosal bleeding times (BMBT) were recorded in blinded fashion before induction and 2, 5, 8, 24, 30, and 48 h post-operation. The average CPSS (mean ± SEM) over 2 to 48 h post-operation in firocoxib-3 (0.4 ± 0.1) was significantly lower than that of the control (0.7 ± 0.2; p = 0.004), but that of firocoxib-1 (0.5 ± 0.2) was not different from that of the control (p = 0.40). The mean CPS of firocoxib-3 was significantly lower than that of the control at 24 h post-operation (p = 0.04); nonetheless, there was no significant difference in mean CPS between firocoxib-1 and control groups at all intervals. BMBT and body temperature were within normal limits in all groups. However, reversible azotemia was identified in two firocoxib-3 cats at 72 h post-operation. One firocoxib-3 cat vomited once at 48 h post-operation. In conclusion, firocoxib-3 is helpful for postoperative pain control in cats; however, gastrointestinal irritation and renal function side effects may occur.

PURPOSE: The aim of the current study is to report the advantage and disadvantage of total hip arthroplasty performed in direct anterior approach (DAA) by comparing it to the posterolateral approach (PLA). MATERIALS AND METHODS: Twenty-five hip arthroplasty done in DAA (12 total hip arthroplasty [THA] and 13 bipolar hemiarthroplasty [BHA]) were compared with the same number done in PLA (13 THA and 12 BHA). Intraoperative assessments including operation time, anesthetic time, bleeding amount were recorded with intraoperative complications. Immediate postoperatively, position of the prosthesis and leg length discrepancy were measured and were compared between the two approaches. RESULTS: The operation time was 22 minutes and 19 minutes longer in DAA for THA and BHA respectively while the anesthetic time difference was 26 and 10 respectively. However, these parameters showed no statistical difference. No significance was found when bleeding amount was compared. For DAA, cup alignment was within safe zone in 100% both for inclination and for anteversion while this was 83.3% and 75.0% respectively in PLA. Leg length difference was 3 mm in DAA and 5 mm in PLA but had no significant difference. Tensor fascia lata tear was the most common complication occurring in 9 patients. CONCLUSION: Although significant was not reached there was trend toward more operation time and anesthetic time when DAA was used. However, the trend also showed that cup and stem were likely to be in more accurate position and in adequate size which is likely due to the accurate use of fluoroscopy.

OBJECTIVE: To determine bleeding time using Moringa oleifera leaf extract versus saline control in an experimental epistaxis model.
METHODS:
Design: Randomized controlled trial
Setting: Tertiary Government Training Hospital
Participants: Ten adult male New Zealand White rabbits were acclimatized for 1 week in a standard environment. One-centimeter long, full-thickness mucosal wounds in the junction of the nasal floor and anterior part of the septum were treated randomly with topical Moringa oleifera extract or colored isotonic saline control in either right or left nasal cavity, one site at a time. The duration of bleeding - time bleeding started to time bleeding stopped -- was recorded in seconds. Data was subjected to a t-test for paired samples.
RESULTS: The mean bleeding time for wounds treated with Moringa extract was 53 seconds (range 38-70 secs), versus 159 seconds (range 100-218 secs) for controls. The bleeding time in the former was significantly shorter than in the latter (p = .000019, t-stat = 8.139), with a mean difference of 106 seconds between the two groups.
CONCLUSION: Moringa oleifera leaf extract was associated with significantly shorter bleeding time than saline control in this experimental epistaxis model and may be worth investigating further as a hemostatic agent for epistaxis.

BACKGROUND: Episiotomy is a surgical incision of the perineum performed to widen the vaginal opening to facilitate the delivery of an infant. Bleeding is its common complication. A certain technique must be followed so as not to incur either dyspareunia, dehiscence or infection. Hence the application of policresulen solution during repair may minimize bleeding and facilitate better wound healing.

OBJECTIVE: To compare the operative and post-operative outcome between episiorraphy with and without application of policresulen solution during repair among puerperal patients admitted in a tertiary hospital.

METHODOLOGY: One hundred participants were randomized to two treatment groups. Those assigned to treatment A (n=50) underwent episiorrhaphy with policresulen solution application while those in treatment B (n=50) served as the control group. The main outcome measures were estimated blood loss, operative time and duration of wound healing.

RESULTS: There was a significantly shorter mean operative time with the participants in the Policresulen group (20.92 ± 0.90 minutes) as compared to the Control group (53.8 ± 1.79 minutes) with a P-value of < 0.001. Estimated mean blood loss was significantly lesser in the Policresulen group (195.2 ± 5.69 ml) than in the Control group (373.8 ± 16.14 ml) having a P-value of < 0.001. The duration of wound healing was also shorter among those in the Policresulen group (1.42 ± 0.09 weeks) than those in the Control group (2.14 ± 0.17 weeks), with a P-value of 0.003. A significantly greater proportion of participants had shorter operative time, lesser blood loss and shorter duration of wound healing in the policresulen group. (p-value < 0.005)

CONCLUSION: Policresulen solution application has a good hemostatic effect on the episiotomy wound hence shortened the operative time. It also has a good wound healing effect reflected by a shortened duration of wound healing of the episiotomy wound.

Our previous study demonstrated that yuzu has an anti-platelet effect in rat blood. In the present study, we examined whether the anti-platelet effect of yuzu can be extended to human blood by investigating its ability to inhibit aggregations induced by various agonists in human platelet rich plasma (PRP). This study also investigated the underlying mechanism of yuzu focusing on ADP granule secretion, TXB2 formations, and PLCgamma/Akt signaling. The results from this study showed that ethanolic yuzu extract (YE), and its components, hesperidin and naringin, inhibited human platelet aggregation in a concentration-dependent manner. YE, hesperidin and naringin also inhibited TXB2 formation and ADP release. The phosphorylation of PLCgamma and Akt was significantly inhibited by YE, heperidin and naringin. Furthermore, we demonstrated that YE, heperidin and naringin has anti-platelet effects in rat ex vivo studies, and lower side effects in mice tail bleeding time studies. The results from this study suggest that YE, hesperidin and naringin can inhibit human platelet aggregation, at least partly through the inhibition of PLCgamma and Akt, leading to a decrease in TXB2 formation and granule secretion.

PURPOSE: The purpose of this study is to analyze the result of secondary total hip arthroplasty (THA) after primary internal fixation failure in femoral neck fracture patients and compare the results with primary THA for femoral neck fracture. MATERIALS AND METHODS: Among the femoral neck fracture patients, we analyzed clininal and radiologic results of those who underwent secondary THA after internal fixation failure and those who underwent THA as early treatment. Cases with patients over age 40 years and with at least two year of follow-up period were used for analysis. Periopertive conditions of patients were evaluated by using surgery time, bleeding amounts and period to start gait using walker or crutch after surgery. Clinical results were assessed by using Harris hip score and Western Ontario and McMaster Universities Osteoarthritis Index, and radiologic results were derived by observing follow-up simpe X-ray. RESULTS: The group of secondary THA had longer surgery time, more bleeding amount and longer period to start gait. But between the two groups, there was no difference of clinical and radiologic result at final follwing up. Both of two group had excellent clinical and radiological results. CONCLUSION: THA after internal fixation showed excellent clinical and radiologic results that was comparable to compare with primary THA.

BACKGROUND/AIMS: Recently, many cases of vitamin K-dependent coagulopathy of unknown origin have been reported. Such patients lack any relevant family history and have no systemic disease, raising suspicion of superwarfarin intoxication. We evaluated individual risk factors causing coagulopathy and hemorrhagic symptoms in patients with suspected superwarfarin intoxication. In addition, we determined how to effectively treat vitamin K-dependent coagulopathy caused by suspected superwarfarin intoxication. METHODS: Seven patients with suspected superwarfarin intoxication who lacked any definitive history of rodenticide ingestion were included. Thirty-one patients initially diagnosed with rodenticide poisoning were also included. We performed a retrospective chart review of all subjects and examined clinical data including patient demographics and medical histories. RESULTS: Patients initially diagnosed with rodenticide poisoning were divided into two groups, one of which had a laboratory abnormality (prothrombin time [PT] > 13 seconds) and another group with PTs in the normal range. There was no significant difference between the two groups in any of age, gender, the extent of chronic alcohol consumption, the causative rodenticide, psychiatric problems, ingestion of drugs interacting with warfarin, the extent of intoxication, or the type of ingestion attempt. The albumin level of the former group was significantly lower than that of the latter group (p = 0.014). Furthermore, a significant difference between the two groups was evident in terms of simultaneous ingestion of rodenticide and alcohol (p = 0.023). CONCLUSIONS: Most patients with superwarfarin poisoning did not exhibit any complication. When such complications were evident, they were associated with serum albumin level and coingestion of rodenticide and alcohol.

BACKGROUND/AIMS: Buttonhole cannulation has been popular because it provides an easy puncture, is less painful, and requires less time for hemostasis. However, the technique requires a skilled staff and a long time to form the tract. A new buttonhole technique using Biohole(TM), which shortens the time needed for tract formation, has been introduced in Europe, North America, and Japan. METHODS: We prepared a cannulation tract using the buttonhole technique and Biohole(TM) over a two-week period and compared the 12-week outcomes between patients who underwent the rope-ladder versus buttonhole techniques. RESULTS: The 40 patients (27 males) had a mean age of 49.1 +/- 14.2 years. Thirteen and 27 patients were cannulated with the rope-ladder and buttonhole techniques, respectively. Patients who underwent the buttonhole technique had more initial pain than did those who received the rope-ladder technique (p = 0.044). The Biohole(TM) procedure improved puncture pain (5.6 vs. 3.4, p = 0.003) and shortened hemostasis time (1.8 vs. 1.3, p = 0.001). Over a two-week period, patients using Biohole(TM) experienced dislocation (20.8%), bleeding at peg sites (8.6%), and pain during peg change (2.4%). Over the 12 week study period, patients who underwent the buttonhole technique had insignificantly less pain than did those who received the rope-ladder technique (p = 0.088), but the former had less bleeding time than the latter (p = 0.000). One patient who received the buttonhole technique experienced one episode of infection (p = 0.327). CONCLUSIONS: The new buttonhole technique using Biohole(TM) is safe and useful in the short term. A long-term, larger, multicenter study is required to confirm these results.

Hemorrhagic complications in patients with end stage renal disease (ESRD) are common. These abnormal bleeding tendencies are caused by several factors including anticoagulation during hemodialysis, anemia, and uremic platelet dysfunction. The most common clinical manifestation of uremic bleeding is hemorrhage of the gastrointestinal tract from gastric ulcer disease. Mediastinal bleeding, however, is rare in ESRD patients. Here, we report a case of spontaneous mediastinal bleeding in a patient with hemodialysis. A huge periesophageal hematoma was observed on the chest CT scan and the bleeding time representing platelet function was prolonged. This case underlies the diversity of uremic bleeding.
