Epistaxis

Preparation and Application of Hemostatic Hydrogels

Hemorrhage remains a critical challenge in various medical settings, necessitating the development of advanced hemostatic materials. Hemostatic hydrogels have emerged as promising solutions to address uncontrolled bleeding due to their unique properties, including biocompatibility, tunable physical characteristics, and exceptional hemostatic capabilities. In this review, a comprehensive overview of the preparation and biomedical applications of hemostatic hydrogels is provided. Particularly, hemostatic hydrogels with various materials and forms are introduced. Additionally, the applications of hemostatic hydrogels in trauma management, surgical procedures, wound care, etc. are summarized. Finally, the limitations and future prospects of hemostatic hydrogels are discussed and evaluated. This review aims to highlight the biomedical applications of hydrogels in hemorrhage management and offer insights into the development of clinically relevant hemostatic materials.

Comparative effectiveness of various noninvasive local treatments in patients with epistaxis: A systematic review and network meta-analysis

BACKGROUND

The best initial strategy for managing epistaxis is unclear. We performed a systematic review and network meta-analysis (NMA) to compare the effectiveness of various noninvasive treatments for patients with epistaxis.

METHODS

We searched PubMed, Embase, and the Cochrane Library from inception to September 2022 without language restrictions. Randomized controlled trials (RCTs) assessing immediate hemostasis, 2-day and 7-day rebleeding outcomes, as well as the use of noninvasive interventions for the treatment of epistaxis were selected. Frequentist NMA was performed.

RESULTS

The systematic review included 20 RCTs (2994 participants) involving 12 different interventions. The NMA demonstrated that topical treatment with tranexamic acid (TXA) significantly reduced the odds of 2-day rebleeding compared with the control conservative treatment (odds ratio [OR] 0.36, 95% confidence interval [CI] 0.21-0.61) and traditional anterior nasal packing (OR 0.45, 95% CI 0.26-0.76). The sensitivity analysis yielded robust results, and the overall evidence was high. Topical TXA significantly reduced the odds of 7-day rebleeding compared with traditional nasal packing (OR 0.33, 95% CI 0.15-0.70), with moderate evidence owing to the heterogeneous results. Despite the significant effects of topical TXA on achieving immediate hemostasis and Rapid Rhino nasal packing on preventing 2-day rebleeding compared to the control and traditional nasal packing, the evidence is low to very low due to heterogeneity, inconsistency, and within-study bias.

CONCLUSIONS

In the treatment of epistaxis, topical TXA may be superior to conservative treatment or traditional nasal packing, particularly in preventing 2-day rebleeding.

ETU-Net: efficient Transformer and convolutional U-style connected attention segmentation network applied to endoscopic image of epistaxis

Epistaxis is a typical presentation in the otolaryngology and emergency department. When compressive therapy fails, directive nasal cautery is necessary, which strongly recommended operating under the nasal endoscope if it is possible. Limited by the operator's clinical experience, complications such as recurrence, nasal ulcer, and septum perforation may occur due to insufficient or excessive cautery. At present, deep learning technology is widely used in the medical field because of its accurate and efficient recognition ability, but it is still blank in the research of epistaxis. In this work, we first gathered and retrieved the Nasal Bleeding dataset, which was annotated and confirmed by many clinical specialists, filling a void in this sector. Second, we created ETU-Net, a deep learning model that smartly integrated the excellent performance of attention convolution with Transformer, overcoming the traditional model's difficulties in capturing contextual feature information and insufficient sequence modeling skills in picture segmentation. On the Nasal Bleeding dataset, our proposed model outperforms all others models that we tested. The segmentation recognition index, Intersection over Union, and F1-Score were 94.57 and 97.15%. Ultimately, we summarized effective ways of combining artificial intelligence with medical treatment and tested it on multiple general datasets to prove its feasibility. The results show that our method has good domain adaptability and has a cutting-edge reference for future medical technology development.

Case report: A case of acquired von Willebrand syndrome as onset clinical presentation of systemic lupus erythematosus manifested as epistaxis and pulmonary hemorrhage

BACKGROUND

Acquired von Willebrand syndrome (AVWS) is a less common bleeding disorder, primarily manifested as mild to moderate mucocutaneous bleeding and laboratory tests are similar to hereditary von Willebrand disease (VWD). AVWS is secondary to other diseases, and systemic lupus erythematosus (SLE) is a relatively rare cause.

CASE PRESENTATION

We report a case of AVWS as onset clinical presentation of SLE manifested as epistaxis and pulmonary hemorrhage. A 13-year-old male child presented to the hospital with a six-month history of recurrent epistaxis and a one-month history of anemia. Routine blood tests demonstrated severe normocytic anemia and normal platelet count. Von Willebrand test revealed a significantly lower level. High-resolution chest computed tomography (CT) showed patchy ground glass opacities consistent with hemorrhagic changes. After ruling out the family history, the patient was diagnosed with AVWS. Additional tests confirmed positive antinuclear and anti-Sm antibodies. The underlying SLE was diagnosed and treated with methylprednisolone with disease recovery.

CONCLUSION

We recommend screening for bleeding disorders in patients with recurrent epistaxis. AVWS should be considered when laboratory findings suggest hereditary von Willebrand disease without a personal or familial history of bleeding. In addition, the underlying disease should be explored.

Nasal Packing in the Emergency Department: A Practical Review for Emergency Providers

We performed a narrative review of epistaxis management in the emergency department. First, we examined the pathophysiology, the current types of treatment that are available to emergency clinicians. When nasal packing is indicated, we examined the efficacy of nasal packing in addition to other topical treatment such as tranexamic acid and the evidence of prophylactic antibiotics. We detailed current studies involving tranexamic acid and prophylactic antibiotics for nasal packing. Finally, we introduced an epistaxis clinical care pathway, based on current evidence, to aid emergency clinicians with their clinical decision-making processes.

Management of Panfacial Trauma: Sequencing and Pitfalls

Panfacial trauma refers to high-energy mechanism injuries involving two or more areas of the craniofacial skeleton, the frontal bone, the midface, and the occlusal unit. These can be distracting injuries in an unstable patient and, as in any trauma, Advanced Trauma Life Support (ATLS) protocols should be followed. The airway should be secured, bleeding controlled, and sequential examinations should take place to avoid overlooking injuries. When indicated, neurosurgery and ophthalmology should be consulted as preservation of brain, vision, and hearing function should be prioritized. Once the patient is stabilized, reconstruction aims to reduce panfacial fractures, restore the horizontal and vertical facial buttresses, and resuspend the soft tissue to avoid the appearance of premature aging. Lost or comminuted bone can be replaced with bone grafts, although adequate reduction should be ensured prior to any grafting. Operative sequencing can be performed from top-down and outside-in or from bottom-up and inside-out depending on patient presentation. All protocols can successfully manage panfacial injuries, and the emphasis should be placed on a systematic approach that works from known areas to unknown areas.
