    OBJECTIVE: To share our experience with a new delivery system for the flowable hemostatic matrix, FloSeal, in endoscopic and microscopic skull base surgery.

    METHODS: We prospectively analyzed the use of FloSeal with a hemostatic delivery system in transnasal endoscopic and microscopic skull base procedures performed at the authors' institution from January 1, 2015, to June 30, 2015. In all cases the number of aliquots was noted for the entire operation, and the total number of FloSeal ampules of 5 mL was also recorded.

    RESULTS: Our device allowed controlled application of small amounts (0.5-1 mL) of FloSeal to the site of bleeding. This controlled application resulted not only in increased visibility during its application, but it also reduced the amount of FloSeal required during the procedure. We were able to use 5-10 applications per 5-mL ampule of FloSeal within an individual procedure. No procedure required more than one 5-mL ampule of FloSeal. Therefore, the use of our device results in a reduction of costs. Prior to the use of our device, we were often only able to use 1 vial of 5 ml of material for 1 or 2 applications, especially in transnasal endoscopic procedures when working along a deep corridor.

    CONCLUSIONS: Our results indicate that our delivery device of FlowSeal can effectively control hemostasis by applying small amounts of FlowSeal to the site of bleeding. This results in increased visibility during hemostasis and a reduction of cost.

    Broad interest in developing new hemostatic technologies arises from unmet needs in mitigating uncontrolled hemorrhage in emergency, surgical, and battlefield settings. Although a variety of hemostats, sealants, and adhesives are available, development of ideal hemostatic compositions that offer a range of remarkable properties including capability to effectively and immediately manage bleeding, excellent mechanical properties, biocompatibility, biodegradability, antibacterial effect, and strong tissue adhesion properties, under wet and dynamic conditions, still remains a challenge. Benefiting from tunable mechanical properties, high porosity, biocompatibility, injectability and ease of handling, polymeric hydrogels with outstanding hemostatic properties have been receiving increasing attention over the past several years. In this review, after shedding light on hemostasis and wound healing processes, the most recent progresses in hydrogel systems engineered from natural and synthetic polymers for hemostatic applications are discussed based on a comprehensive literature review. Most studies described used in vivo models with accessible and compressible wounds to assess the hemostatic performance of hydrogels. The challenges that need to be tackled to accelerate the translation of these novel hemostatic hydrogel systems to clinical practice are emphasized and future directions for research in the field are presented.

    Platelets, along with coagulation factors and vasculature, represent the three main compartments of hemostasis. Upon investigation of a suspected hemostasis disorder, platelet count, size and morphology often offer important clues to the diagnosis or help narrow the differential diagnosis. In this review, we describe a general approach to diagnosing platelet disorders, starting with easily obtained data such as findings of complete blood count (CBC) and microscopic review of a stained peripheral blood smear. We discuss general findings that help separate consumptive from underproduction thrombocytopenia. We further touch on inherited thrombocytopenia disorders after classifying them into those associated with small, normal sized or large platelets. Illustrative microscopic images are provided where contributory. We conclude with a suggested algorithmic step-by-step approach to investigating a suspected platelet disorder in children.

    BACKGROUND: A good control of intraoperative bleeding is key for adequate anatomical visualization during endoscopic sinus surgery (ESS). The objective of this review was to assess the practice of hot intranasal saline irrigation (HSI) in achieving intraoperative hemostasis and good surgical field quality during ESS.

    METHODS: An electronic search was performed via PubMed, SCOPUS, Google Scholar, and Cochrane from inception to June 2022. The included trials were evaluated according to the recommendations of the Cochrane Handbook for Systematic Reviews. The primary outcome assessed was the intraoperative bleeding score of the surgical field. The mean arterial pressure, duration of the surgery, amount of blood loss and surgeon's satisfaction score were assessed as the secondary outcomes. The risk of bias for each study was evaluated using the Cochrane risk of bias tool.

    RESULTS: A total of 254 records were identified after removal of duplicates. Based on the title and abstract 246 records were excluded, leaving seven full texts for further consideration. Five records were excluded following full text assessment. Three trials with a total of 212 patients were selected. Hot saline irrigation was superior to control in the intraoperative bleeding score (MD - 0.51, 95% CI - 0.84 to - 0.18; P < 0.001; I2 = 72%; very low quality of evidence) and surgeon's satisfaction score (RR 0.18, 95% CI 0.09 to 0.33; P < 0.001; I2 = 0%; low quality of evidence). The duration of surgery was lengthier in control when compared to HSI (MD - 9.02, 95% CI - 11.76 to - 6.28; P < 0.001; I2 = 0; very low quality of evidence). The volume of blood loss was greater in control than HSI (MD - 56.4, 95% CI - 57.30 to - 55.51; P < 0.001; I2 = 0%; low quality of evidence). No significant difference between the two groups for the mean arterial pressure was noted (MD - 0.60, 95% CI - 2.17 to 0.97; P = 0.45; I2 = 0%; low quality of evidence).

    CONCLUSIONS: The practice of intranasal HSI during ESS is favorable in controlling intraoperative bleeding and improving the surgical field quality. It increases the surgeon's satisfaction, reduces blood loss, shortens operative time and has no effect on intraoperative hemodynamic instability.

    Pre-operative embolisation of vertebral metastases has been known to effectively devascularise hypervascular vertebral tumours and to reduce intra-operative bleeding. However, the complications that occur during the procedure are rarely reported. This case study attempts to highlight one rare complication, which is epidural tumoural haemorrhage intra-procedure. It may occur due to the fragility of the tumour and presence of neovascularisation. A small arterial dissection may also have occurred due to a slightly higher pressure exerted during injection of embolising agent. Haemostasis was secured via injection of Histoacryl into the area of haemorrhage. The patient was able to undergo the decompression surgery and suffered no direct complication from the haemorrhage.

    Vulvo-vaginal haematomas are not an uncommon obstetric complication. Despite advances in obstetric care, practice and technique, vulvo-vaginal haematomas do occur especially in complicated vaginal deliveries. Various management options are available for vulvo-vaginal haematomas. We describe three cases of vulvo-vaginal haematomas with different severity and presentations which were managed in different manners i.e. local haemostasis control, laparotomy with hysterectomy, and transarterial embolisation. The choice of treatment options would mainly depend on the clinical presentations, availability of expertise as well as facilities. Early identification is crucial.

    The International Society of Thrombosis and Hemostasis (ISTH) provides objective disseminated intravascular coagulation (DIC) measurement through diagnostic criteria validated in adults. The applicability of these criteria in pediatric and neonatal DIC is controversial and unvalidated. Primary objective: to evaluate current practice in pediatric and neonatal DIC management among different specialties. Secondary objective: to understand the potential impact of developmental hemostasis on DIC laboratory evaluation. We performed a multicenter survey between January and September 2016. The questionnaire was distributed internationally through professional societies. In all, 211 responses were received, of which 160 were full responses and 51 were partial. Overall, 85% of respondents practiced in tertiary academic centers; 70% practiced in pediatric-only hospitals. The majority of respondents (42%) used their personal clinical experience in the management of DIC. Sixty percent of respondents treated DIC until the resolution of both clinical and laboratory parameters. Laboratory investigations were monitored in the majority of DIC cases without thrombosis or bleeding (80%); age-specific reference ranges for tests were lacking in 20% of pediatric-only hospitals and 35% of combined pediatric/adult hospitals. Adherence to standardized DIC guidelines was poor but varied by geographical location. This survey reveals variable practices among pediatricians in the management of DIC. Further studies are needed to validate the DIC diagnostic criteria in children.

    In endoscopic neurosurgery problems with haemostasis due to poor access exist. We have developed a system which allows the delivery of a variety of haemostatic agents in a more efficacious manner. The system has been used successfully in endoscopic skull base surgery and endoscopic surgery within the parenchyma of the brain using tube systems.

    BACKGROUND: Application of principles of electrocautery for hemostasis dates back to prehistoric times. Its modern implementation in various fields of general and head and neck surgeries have been well documented. However its usage in minor oral surgical procedures has gained popularity only recently. Complications associated with electro-surgery in the dental field are relatively rare and there is insufficient literature on its management.

    CASE REPORT: We present a case report on management of an electrosurgery induced osteonecrosis involving maxillary alveolus of left premolars.

    DISCUSSION: Inadvertent contact of the electrosurgery tip on bone can result in necrosis making it necessary to remove the sequestrum and graft the defect. Platelet rich fibrin in combination with bone grafts have been well documented to provide successful periodontal regeneration.

    CLINICAL IMPLICATIONS: Our aim of presenting this report is to create awareness among the health care providers regarding electrosurgical injuries. To our knowledge, this is the first time platelet rich fibrin has been used in the management of intraoral electrosurgical injury. Combining bone grafts with platelet rich fibrin is a good alternative as it can be done with relative ease and predictable outcome.

    Haemothorax is one of the less common presentations that requires hospital admission. Most cases are associated with underlying causes, but there is such an entity called spontaneous haemothorax. Spontaneous haemothorax is commonly associated with adhesions within the pleural cavity. Here, we reported two cases of young adults who presented with massive spontaneous haemothorax and required emergency thoracotomy for haemostasis purpose.

    Bleeding is a serious complication of peptic ulcer and mortality rate has remained at approximately 10% or more. Traditionally surgeons selected patients who were at significant risk of continued or re-bleeding and advocated early surgery. However, patients with bleeding peptic ulcers are generally elderly with coexisting medical illness and surgery results in significant morbidity and mortality. In the last decade, endoscopic haemostatic therapy has been effective in arresting the bleeding with surgical option considered only after endoscopic treatment has failed. We report the outcome of 196 patients who were endoscopically diagnosed to have bleeding from peptic ulcers. One hundred and thirty patients were to have active bleeding or recent bleed from the ulcer. Endoscopic adrenaline injection therapy was used in 53 patients who had active bleeding ulcers and another 77 patients with endoscopic evidence of recent bleed. The injection therapy was successfully in 127 (97.7%) patients. The treatment failed in three patients and they underwent urgent surgery. Re-bleeding occurred in 26 (20.5%) patients and endoscopic adrenaline therapy was repeated in these cases. Haemostatic was achieved in 19 patients, however 7 patients continued to bleed and required surgery. There were 3 deaths, principally from advanced age and coexisting medical illness. Endoscopic therapy for bleeding peptic ulcers is simply to apply, safe and effective. In cases of re-bleeding after initial endoscopic hemostasis, re-treatment is a preferable alternative to surgery. The role of surgery is limited to bleeding that is refractory or inaccessible to endoscopic control.

    Glomus tympanicum is a highly vascular tumour traditionally treated surgically via a post-auricular approach. We present here the first published case in Malaysia where total excision was achieved transcanal endoscopically. The procedure was safe, quick and effective due to the better visualisation of the surgical field with the endoscope. Haemostasis was achieved with a modified suction catheter that performed as a functioning suction diathermy.

    Disseminated intravascular coagulation (DIC) in paediatrics is associated with significant morbidity and mortality. Although there have been several recent advances in the pathophysiology of DIC, most of these studies were done in adults. Since the haemostatic system is very different in early life and changes dramatically with age, creating a variety of challenges for the clinician, delay in the diagnosis of DIC can happen until overt DIC is evident. In this review article, we report the aetiology, pathophysiology, clinical manifestations, diagnostic tests and a management algorithm to guide paediatricians when treating patients with DIC.

    INTRODUCTION: Surgery in patients with haemophilia B carries a high risk of excessive bleeding and requires adequate haemostatic control until wound healing. Nonacog beta pegol, a long-acting recombinant glycoPEGylated factor IX (FIX), was used in the perioperative management of patients undergoing major surgery.
    AIM: To evaluate the efficacy and safety of nonacog beta pegol in patients with haemophilia B who undergo major surgery.
    METHODS: This was an open-label, multicentre, non-controlled surgery trial aimed at assessing peri- and postoperative efficacy and safety of nonacog beta pegol in 13 previously treated patients with haemophilia B. All patients received a preoperative nonacog beta pegol bolus injection of 80 IU kg-1 . Postoperatively, the patients received fixed nonacog beta pegol doses of 40 IU kg-1 , repeated at the investigator's discretion. Safety assessments included monitoring of immunogenicity and adverse events.
    RESULTS: Intraoperative haemostatic effect was rated 'excellent' or 'good' in all 13 cases. Apart from the preoperative injection, none of the patients needed additional doses of nonacog beta pegol on the day of surgery. The median number of postoperative doses of nonacog beta pegol was 2.0 from days 1 to 6 and 1.5 from days 7 to 13. No unexpected intra- or postoperative complications were observed including deaths or thromboembolic events. No patients developed inhibitors.
    CONCLUSIONS: These results indicated that nonacog beta pegol was safe and effective in the perioperative setting, allowing major surgical interventions in patients with haemophilia B with minimal peri- and postoperative concentrate consumption and infrequent injections as reported with standard FIX products.

    Background: Vasoactive drugs are frequently used in combination with endoscopic variceal ligation (EVL) in treatment of acute esophageal variceal bleeding (EVB). The aim of study was to assess physicians' preference of vasoactive agents in acute EVB, their reasons of preference and efficacy and safety of these short course regimens.

    Methods: Cirrhotic patients with suspected EVB were screened (n = 352). Eligible patients were assigned based on the physician's preference to either somatostatin (group S) or terlipressin (group T) followed by EVL. In group S, intravenous bolus (250 µg) of somatostatin followed by 250 µg/hour was continued for three days. In group T, 2 mg bolus injection of terlipressin was followed by 1 mg infusion every 6 h for three days.

    Results: A total of 150 patients were enrolled; 41 in group S and 109 in group T. Reasons for physician preference was convenience in administration (77.1%) for group T and good safety profile (73.2%) for group S. Very early rebleeding within 49-120 h occurred in one patient in groups S and T (p = 0.469). Four patients in group S and 14 patients in group T have variceal rebleeding episodes within 6-42 d (p = 0.781). Overall treatment-related adverse effects were compatible in groups S and T (p = 0.878), but the total cost of terlipressin and somatostatin differed i.e., USD 621.32 and USD 496.43 respectively.

    Conclusions: Terlipressin is the preferred vasoactive agent by physicians in our institution for acute EVB. Convenience in administration and safety profile are main considerations of physicians. Safety and hemostatic effects did not differ significantly between short-course somatostatin or terlipressin, although terlipressin is more expensive.

    Wound healing is a complex biological process that is generally composed of four phases: hemostasis, inflammation, proliferation, and remodeling. The proliferation phase is crucial for effective healing compared to other phases. Many critical events occur during this phase, i.e., migration of fibroblasts, re-epithelialization, angiogenesis and wound contraction. Chronic wounds are common and are considered a major public health problem. Therefore, there is the increasing need to discover new therapeutic strategies. MicroRNA (miRNA) research in the field of wound healing is in its early phase, but the knowledge of the recent discoveries is essential for developing effective therapies for the treatment of chronic wounds. In this review, we focused on recently discovered miRNAs which are involved in the proliferation phase of wound healing in the past few years and their role in wound healing.

    The administration of intrapleural streptokinase (IPSK) is widely practiced in the management of loculated empyema thoracis. To our knowledge, there have been only 4 cases of hemorrhagic complications attributed to the administration of IPSK reported in the literature. In this article, we report a case of a 17-year-old girl who received IPSK and developed shock, anemia, coagulopathy and massive hemothorax. Our discussion focuses on the hemorrhagic complication of chest tube insertion and the role of IPSK in blood clot lysis and inhibition of local hemostasis.

    Intramural duodenal haematoma is a rare injury of the duodenum. Most reported cases are secondary to blunt trauma to the abdomen. Such injury following endoscopic intervention is even rarer, and there are no definite guidelines for its management. We report a case where endoscopic haemostasis of a bleeding duodenal ulcer resulted in a massive dissecting intramural duodenal haematoma with gastric outlet obstruction and obstructive jaundice.
