BACKGROUND: Delayed epistaxis after endoscopic transnasal pituitary tumor resection (ETPTR) is a critical complication, tending to cause aspiration or hemorrhagic shock. This study assessed clinical characteristics, risk factors, and provide treatment and prevention advice of this complication.
METHODS: This was a retrospective monocentric analysis of 862 patients who underwent ETPTR. Statistical analyses of clinical data revealed the incidence, sources and onset time of delayed epistaxis. Univariate analysis and binary logistic regression were used to identify risk factors.
RESULTS: The incidence of delayed epistaxis was 2.78% (24/862), with an average onset time of 20.71 ± 7.39 days. The bleeding sources were: posterior nasal septal artery branch of sphenopalatine artery (12/24), multiple inflammatory mucosae (8/24), sphenopalatine artery trunk (3/24) and sphenoid sinus bone (1/24). Univariate analysis and binary logistic regression analysis confirmed that hypertension, nasal septum deviation, chronic rhinosinusitis and growth hormone pituitary tumor subtype were independent risk factors for delayed epistaxis. Sex, age, history of diabetes, tumor size, tumor invasion and operation time were not associated with delayed epistaxis. All patients with delayed epistaxis were successfully managed through endoscopic transnasal hemostasis without recurrence.
CONCLUSIONS: Delayed epistaxis after ETPTR tends to have specific onset periods and risk factors. Prevention of these characteristics may reduce the occurrence of delayed epistaxis. Endoscopic transnasal hemostasis is recommended as the preferred treatment for delayed epistaxis.

UNASSIGNED: Background. Epistaxis is frequently observed in allergic rhinitis (AR) patients. However, few studies focus on the outcome of epistaxis with treatment of AR patients. This study aimed to retrospectively analyze the efficacy and safety of AR patients with epistaxis treated with sublingual immunotherapy (SLIT). Methods. A total of 74 patients aged 4-60 years with house dust mite (HDM)-induced AR accompanied by epistaxis and who completed 1 year of SLIT treatment with standard Dermatophagoides farinae (D. farinae) drops were enrolled in this study. The symptom scores, total medication scores (TMS), combined symptom and medication score (CSMS), visual analog scales (VAS), and bleeding score (BS) were assessed, as well as the nasal endoscopic examinations were performed to observe nasal signs. Results. The levels of symptom scores, TMS, CSMS, VAS, and BS at 0.5 year and 1 year of SLIT treatment were significantly lower than those at the baseline (all p less than 0.01). Also, statistical differences were seen in CSMS (p less than 0.05) and VAS (p less than 0.01) between 0.5 year and 1 year. As expected, BS was positively correlated with CSMS (r = 0.617, 95% CI 0.517-0.699) and VAS (r = 0.777, 95% CI 0.719-0.822) at all three time points. Conclusions. SLIT with D. farinae drops was effective and safe for AR patients with epistaxis, resulting in improving the symptoms of rhinitis while relieving the symptoms of epistaxis.

Retiform hemangioendothelioma (RH) is a rare intermediate (locally aggressive) vascular tumor that mostly affects the dermis of the trunk and limbs, but has never been reported in the inferior turbinate. A 10-year-old Chinese boy presented with recurrent epistaxis in his left nasal cavity and anemia for more than 2 years. Radiographic and electronic video laryngoscopic images showed an expansile mass in the left inferior turbinate. Endoscopic surgery and electrocautery were performed to resect the tumor beyond the macroscopic border. Histopathologically, the tissues were infiltrated by hyperplastic blood vessels arranged in a retiform pattern, and endothelial cells proliferate significantly in some areas. Immunohistochemistry showed a positive result for CD31, CD34, Fli-1, and ERG. No epistaxis, tumor recurrence, or metastasis was found on reexamination over 18 months after surgery.

Objectives: This project aims to explore the relationship between the air quality index (AQI), the concentration of 6 air pollutants, and the incidence of epistaxis in Yangzhou. Also, to provide reference information for the prevention and treatment of epistaxis. Methods: Data of patients with epistaxis admitted to the Northern Jiangsu People\'s Hospital Affiliated to Yangzhou University from January 2017 to December 2021 were collected. In addition, the local AQI and the concentrations of 6 air pollutants, namely particulate matter (PM2.5, PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and ozone (O3), were analyzed at the time of onset. Furthermore, the correlation with the incidence of epistaxis has been analyzed. Results: From 2017 to 2021, there were 24,721 patients with epistaxis aged from 0 to 17 years old while male patients were more than females. The incidence was higher in April, May, and June. There was a statistically significant difference in the number of daily epistaxis in different months and under AQI conditions (P < .05). Spearman\'s correlation analysis showed that there was a positive correlation between the number of daily epistaxis and the concentrations of AQI, CO, NO2, O3, PM2.5, PM10, and SO2 in Yangzhou, in which O3, PM10, and SO2 were highly correlated with the average number of daily epistaxis, and there was no obvious time lag effect of air pollutants on epistaxis. Conclusion: Epistaxis in the Yangzhou area is more common in males, mostly occurs in 0 to 17 years old, with seasonal. There was also a positive correlation between the incidence of epistaxis and air pollutants in Yangzhou. Therefore, by reducing the AQI index in daily life, and reducing the concentration of environmental pollutants in the air, the occurrence of epistaxis could be prevented and reduced to a certain extent.

BACKGROUND: Epistaxis is one of the common emergencies in otolaryngology. There are many causes of epistaxis, but reports of epistaxis due to nasal foreign bodies like leeches are rare.
METHODS: A 55-year-old male presented with \"repeated epistaxis for over 20 days.\" Nasal endoscopy revealed a live leech in the olfactory area of the left nostril.
METHODS: The patient was diagnosed with epistaxis caused by a live leech in the nasal cavity.
METHODS: Under nasal endoscopy, the leech was grasped with a vascular clamp and removed from the nasal cavity. The leech measured 8 cm in length. Hemostasis was achieved using a gelatin sponge at the wound site, and the nasal cavity was packed with Vaseline gauze.
RESULTS: The live leech was removed via nasal endoscopy. Two days later, the Vaseline gauze packing was removed, and the patient experienced no further nasal bleeding.
CONCLUSIONS: Live leeches in the nasal cavity can cause epistaxis. Nasal endoscopic removal of the live leech is an effective treatment.
CONCLUSIONS: There are many causes of epistaxis, which are nonspecific and prone to missed or incorrect diagnosis. In patients with a history of fieldwork or direct contact with leeches who present with recurrent nasal bleeding, the possibility of epistaxis caused by a live leech should be considered, and timely and effective treatment should be provided.

We present a rare case of Lymphoplasmacytic Lymphoma/Waldenström Macroglobulinemia (LPL/WM) diagnosed in a 65-year-old female initially presenting with recurrent bilateral epistaxis. Despite multiple cauterizations and a history of ineffective conventional treatments, comprehensive evaluations led to the diagnosis, underscoring the critical need for thorough investigation in persistent epistaxis cases, particularly when standard approaches fail. This case emphasizes the importance of considering indolent lymphomas in the differential diagnosis of recurrent epistaxis and showcases the diagnostic pathway leading to successful identification and treatment of a rare etiology.

OBJECTIVE: This study aims to investigate the bleeding sites and their relationship with clinical characteristics in hospitalized epistaxis patients.
METHODS: We retrospectively reviewed the data of 646 hospitalized epistaxis patients.
RESULTS: The bleeding sites were identified in 395 (61.1%) patients and unidentified in 251 (38.9%). We found that age > 50 years (P = 0.030) and the history of cardiovascular diseases (P = 0.027) were more frequent in patients with unidentified bleeding sites. Among patients with identified sites, inferior meatus (n = 130, 32.9%) was the most common site, followed by the septal surface of the olfactory region (n = 102, 25.8%), nasal septum (n = 80, 20.3%), middle meatus (n = 60, 15.2%), and others (n = 23, 5.8%). After dividing patients into five groups by the area of the bleeding sites, we found significant differences in age (P = 0.026), history of hypertension (P = 0.001), cardiovascular diseases (P = 0.032), and nasal packing (P = 0.011). The logistic regression also revealed that these four factors were predictors for different bleeding sites.
CONCLUSIONS: The bleeding sites can be identified in most epistaxis patients. Age > 50 years and the history of cardiovascular diseases are more frequent in patients with unidentified bleeding sites. In our patients, the most common bleeding site is inferior meatus, followed by the septal surface of the olfactory region, nasal septum, and middle meatus. Age, histories of hypertension, cardiovascular diseases, and nasal packing are factors associated with the bleeding risks of different bleeding sites. According to the different clinical characteristics of patients, the order of the nasal endoscopic examination should be adjusted to develop their treatment plans.

BACKGROUND: Paranasal sinus angiosarcoma is an uncommon malignancy, with only a few reported cases worldwide. Although it exhibits multiple symptoms, facial paralysis has not been previously documented as a noticeable presentation.
METHODS: In this case, we report a 40-year-old male who presented with facial numbness and pain for one month, weakness of his facial muscles for 15 days, and recurrent right epistaxis for 1 year. He had a history of nasal inflammatory polyps with chronic sinusitis. Computed tomography and magnetic resonance imaging showed space-occupying lesions in the right nasal cavity and maxillary sinus, with bone destruction occurring in the sinus wall and turbinate. This patient then underwent endoscopic surgery. According to the histopathological and immunohistochemical results, he was eventually diagnosed with paranasal sinus angiosarcoma in April 2021. To date, this patient has not initiated any radiotherapy or chemotherapy and has survived with lymphatic metastasis for at least 3 years.
CONCLUSIONS: This manuscript suggests that paranasal sinus angiosarcoma can present with facial paralysis. Moreover, pathological and immunohistochemical tests are still vital for diagnosing paranasal sinus angiosarcoma and differential diagnosis. Additionally, regular follow-up is crucial for patients with paranasal sinus angiosarcoma, enabling monitoring of recurrence, metastasis, and recovery while contributing valuable clinical data to understanding this rare disease and associated research endeavours.
