Effect of nursing intervention on rehabilitation of patients with chronic sinusitis and nasal polyps after nasal endoscopy

BACKGROUND Chronic sinusitis is a kind of chronic suppurative inflammation of the sinus mucosa.Nasal endoscopy is a good method to treat nasal polyps.However postoperative rehabilitation and care should not be neglected.AIM To investigate the Effect of nursing intervention on the rehabilitation of patients with chronic sinusitis and nasal polyps(CSNPS)after nasal endoscopy.METHODS A total of 129 patients with CSNPS hospitalized from February 2017 to February 2019 were studied.Using the digital parity method,we investigated nursing cooperation strategies for endoscopic surgery.The comparison group(64 cases):Surgical nursing was carried out with traditional nursing measures;experimental group(65 cases):Surgical nursing was carried out by traditional nursing countermeasures+comprehensive nursing measures.We compared postoperative recovery rates,nursing satisfaction rates,and nasal cavity ratings between the two groups.RESULTS Experimental group patients with CSNPS had a significantly higher recovery rate(98.46%)compared to the control group(79.69%).This difference was statistically significant(χ2=11.748,P<0.05).Additionally,the satisfaction rate with treatment was also significantly higher in the experimental group(98.46%)compared to the control group(79.69%),with a statistically significant difference(χ2=11.748,P<0.05).Before nursing,there was no significant difference in sinus nasal cavity scores between the experimental group(20.29±7.25 points)and the control group(20.30±7.27 points)(t=0.008,P>0.05).However,after nursing,the sinus nasal cavity score in the experimental group(8.85±3.22 points)was significantly lower than that in the control group(14.99±5.02 points)(t=8.282,P<0.05).CONCLUSION Comprehensive nursing intervention in patients with CSNPS can significantly improve the total recovery rate after endoscopic surgery.

Treatment of primary nasal tuberculosis with anti-tumor necrosis factor immunotherapy:A case report

BACKGROUND Primary nasal tuberculosis(TB)is a rare form of extrapulmonary TB,particularly in patients receiving anti-tumor necrosis factor(TNF)immunotherapy.As a result,its diagnosis remains challenging.CASE SUMMARY A 58-year-old male patient presented to the ear,nose,and throat department with right-sided nasal obstruction and bloody discharge for 1 month.He was diagnosed with psoriatic arthritis and received anti-TNF immunotherapy for 3 years prior to presentation.Biopsy findings revealed chronic granulomatous inammation and a few acid-fast bacilli,suggestive of primary nasal TB.He was referred to our TB management department for treatment with oral anti-TB agents.After 9 months,the nasal lesions had disappeared.No recurrence was noted during follow-up.CONCLUSION The diagnosis of primary nasal TB should be considered in patients receiving TNF antagonists who exhibit thickening and crusting of the nasal septum mucosa or inferior turbinate,particularly when pathological findings suggest granulomatous inflammation.

Adipose-derived mesenchymal stem cell-incorporated PLLA porous microspheres for cartilage regeneration

Background:In facial plastic surgery,patients with nasal deformity are often treated by rib cartilage transplantation.In recent years,cartilage tissue engineering has developed as an alternative to complex surgery for patients with minor nasal defects via injection of nasal filler material.In this study,we prepared an injectable nasal filler material containing poly-L-l actic acid(PLLA)porous microspheres(PMs),hyaluronic acid(HA)and adipose-derived mesenchymal stem cells(ADMSCs).Methods:We seeded ADMSCs into as-prepared PLLA PMs using our newly invented centrifugation perfusion technique.Then,HA was mixed with ADMSC-i ncorporated PLLA PMs to form a hydrophilic and injectable cell delivery system(ADMSCincorporated PMH).Results:We evaluated the biocompatibility of PMH in vitro and in vivo.PMH has good injectability and provides a favorable environment for the proliferation and chondrogenic differentiation of ADMSCs.In vivo experiments,we observed that PMH has good biocompatibility and cartilage regeneration ability.Conclusion:In this study,a injectable cell delivery system was successfully constructed.We believe that PMH has potential application in cartilage tissue engineering,especially in nasal cartilage regeneration.

Nasal congestion caused by long-term retention of a nasal foreign body near the orbit:A case report

BACKGROUND Nasal trauma presents a risk of foreign body invasion into the nasal cavity.However,in the early treatment stage of nasal trauma,patients and doctors are not always aware of possible foreign body invasion,resulting in delayed detection.We describe the case of an adult patient admitted to the hospital due to left nasal congestion accompanied by yellow,purulent,and bloody discharge.CASE SUMMARY Consultation with the patient revealed a history of nasal trauma 30 years prior that did not receive thorough examinations and imaging during treatment,resulting in a glass fragment retained in the nasal cavity adjacent to the orbit.After admission,computerized tomography(CT)confirmed the presence of the foreign body in the patient’s left nasal–maxillary sinus.The nasal foreign body led to symptoms such as chronic sinusitis,nasal polyps,fungal infection,and deviated nasal septum.The foreign body was successfully removed by nasal endoscopy,polypectomy,sinus fungal removal,left middle turbinate conchoplasty,fenestration via the right inferior meatus,nasal endoscopic maxillary sinus cystectomy,and septolplasty.The operation was successful and without any complications.CONCLUSION CT scans should be performed in addition to necessary debridement sutures to avoid possible foreign body invasion during nasal trauma.Surgical planning should be tailored to the patient’s specific situation.The surgical method should be carefully selected,and sufficient preparation should be undertaken before the surgery to avoid possible displacement of the nasal foreign body.

Postoperative pneumocranium after endoscopic transnasal optic canal decompression

Dear Editor,We present the first time,a case of a patient developed cerebrospinal fluid(CSF)leak and pneumocranium following optic canal decompression(OCD).INTRODUCTION Indirect traumatic optic neuropathy(ITON)impairs visual functions and quality of life.Endoscopic transnasal optic canal decompression(ETOCD)is one of the standard treatment strategies for the ITON.During the ETOCD,the optic nerve sheath are usually incised for sufficient decompression of optic nerve after removal of optic canal,which is associated with complications like CSF leakage,ophthalmic artery injury,and optic nerve injury[1].Generally,the mild CSF leak is common and can heal spontaneously using conventional treatment,the severe CSF leak requires surgical repair[2].

Classification and reconstructive algorithm for nasal alar defect in Asians

Background:The nasal alar defect in Asians remains a challenging issue,as do clear classification and algorithm guidance,despite numerous previously described surgical techniques.The aim of this study is to propose a surgical algorithm that addresses the appropriate surgical procedures for different types of nasal alar defects in Asian patients.Methods:A retrospective case note review was conducted on 32 patients with nasal alar defect who underwent reconstruction between 2008 and 2022.Based on careful analysis and our clinical experience,we proposed a classification system for nasal alar defects and presented a reconstructive algorithm.Patient data,including age,sex,diagnosis,surgical options,and complications,were assessed.The extent of surgical scar formation was evaluated using standard photography based on a 4-grade scar scale.Results:Among the 32 patients,there were 20 males and 12 females with nasal alar defects.The predominant cause of trauma in China was industrial factors.The majority of alar defects were classified as type Ⅰ C(n=8,25%),comprising 18 cases(56.2%);there were 5 cases(15.6%)of type Ⅱ defect,7(21.9%)of type Ⅲ defect,and 2(6.3%)of type Ⅳ defect.The most common surgical option was auricular composite graft(n=8,25%),followed by bilobed flap(n=6,18.8%),free auricular composite flap(n=4,12.5%),and primary closure(n=3,9.4%).Satisfactory improvements were observed postoperatively.Conclusion:Factors contributing to classifications were analyzed and defined,providing a framework for the proposed classification system.The reconstructive algorithm offers surgeons appropriate procedures for treating nasal alar defect in Asians.

Early screening to identify and diagnose primary nasal tuberculosis in patients with tumor necrosis factor inhibitors

In this editorial,we comment on the article by Liu et al.Based on our analysis of a case report,we consider that early screening and recognition of primary nasal tuberculosis are crucial for patients undergoing treatment with tumor necrosis factor inhibitor(TNFi).While TNFi therapy increases the risk of reactivating latent tuberculosis,primary nasal tuberculosis remains rare due to the protective mechanisms of the nasal mucosa.Risk factors for primary nasal tuberculosis include minimally invasive nasal surgery,diabetes,and human immunodefi ciency virus.Patients with early symptoms such as nasal congestion,rhinorrhea,altered olfaction,epistaxis,or ulceration,and unresponsive to conventional antibiotics and antihistamines should undergo early rhinoscopy,possibly followed by repeated tissue biopsies and acid-fast bacilli culture when necessary.When diagnosis is challenging,it is essential to consider local tuberculosis epidemiology and the efficacy of diagnostic antituberculosis treatment.The preferred method for tuberculosis screening is the Interferon Gamma Release Assay,with a general recommendation for screening at 3 and 6 months after initial treatment and then every six months.However,the optimal frequency is not yet consensus-driven and may be increased in economically viable settings.

Classification and a decade-long follow-up of rat bite injuries in the nasal region

Background:Nasal defects due to rat bites are frequently encountered in rural regions of China.In addition to serving as disease vectors,rats can also inflict bite injuries.In this study,we delineated the characteristics of rat bite injuries in the nasal region and discussed the clinical features observed during a 10-year follow-up period.Methods:We retrospectively reviewed hospital records for patients admitted due to rat bites.This study outlines the demographics,clinical features,and follow-up outcomes supported by comprehensive photo documentation of the patients’progress.Results:Twenty-five patients,with a mean age of 29 years,were admitted due to rat bites.Treatment was provided for three distinct types of injuries:nasal tip defect(type Ⅰ),nasal defect(type Ⅱ),and full-thickness nasal defect with loss of surrounding tissues(type Ⅲ).All patients recovered fully.Conclusions:The treatment for rat bites should be based on the wound type.The long-term follow-up outcomes are more favorable when fewer subunits of the nose affected.We recommend early surgical intervention,along with psychological therapy,to prevent interference with growth and development.

Principles and Techniques of Post-Traumatic Rhinoplasty: A Review of the Literature

Post-traumatic rhinoplasty is the surgical treatment of the complex functional and aesthetic sequelae of nasal trauma. Correcting a post-traumatic nose is a challenging task, requiring the surgeon to employ a range of techniques and grafts to adequately address the deformities observed. The results of our research show that restoring pre-traumatic form and function remains complex, although many guidelines have been established to refine and optimize the management of the after-effects of nasal trauma. But it is achievable with the right techniques. The objective of our review is to highlight the various post-traumatic nasal sequelae, describe the fundamental principles in the field of post-traumatic rhinoplasty and provide the surgeon with the various existing surgical techniques and strategies so that he or she can make an appropriate choice for the patient.

Nasal Dermoid Cyst with Sinus Tract Intranasal Bone: A Case Report

Dermoid cysts are benign tumors originating from germ cells, which can form in various locations, including the nasal area in rare cases. They are of unknown exact etiology, but it is suggested that it is due to abnormal tissue migration during early embryonic development. Nasal dermoid cysts albeit rare, can present in various forms such as sinuses, fistulas, or intracranially extending tracts. They can be asymptomatic and incidentally discovered or present with a visible external mass or sinus that is either painful, infected or cosmetically concerning. If nasal dermoid cysts with an intra-nasal bone sinus tract are left untreated, they can lead to life-threatening complications. This report describes the case of a 6-year-old girl with a nasal dermoid cyst connected to a superficial punctum by an intra-nasal tract. She had undergone surgical excision of a nasal swelling previously diagnosed as a dermoid cyst. One year later, she returned to our clinic with a recurrence of the nasal swelling. Imaging tests revealed a nasal dermoid cyst with a tract extending to the nasal tip, without intracranial expansion. The cyst, along with the entire tract, was successfully removed surgically, and the postoperative follow-up indicated no complications. Histopathology confirmed the diagnosis of a dermoid cyst. This case underscores the significance of considering the dermoid tract in nasal cyst cases and the necessity of its complete removal to prevent recurrence.

Unilateral Choanal Atresia in Adults: A Case Series

Choanal atresia (CA) is a rare occlusion of the posterior choanae. Unilateral cases have been reported more than bilaterally, and it’s more often right-sided in those patients. According to the literature, mixed bony-membranous atresia is the most common type. There is a high incidence of craniofacial and visceral anomalies associated with congenital choanal atresia. Therefore, investigation for associated congenital anomalies is an important step before the surgery. We report 2 cases of incidental finding of unilateral choanal atresia in a 21- and 17-year-old with nasal discharge being the only complaint in the former and nasal obstruction with headache in the latter. The patients were then scheduled for day-surgery as a case of choanal atresia for transnasal, endoscopic repair and posterior septectomy. The patients were discharged home on the same day with the absence of restenosis or other complications.

水杨酸钠对阳离子Gemini表面活性剂水溶液中蠕虫状胶束形成和性质的影响(英文)

用稳态和震荡剪切实验研究了水杨酸钠(NaSal)对50mmo·lL-1阳离子Gemini表面活性剂2-羟基-(三亚甲基-α,ω-双十二烷基三甲基溴化铵和三亚甲基-α,ω-双十二烷基三甲基溴化铵,简写为12-3(OH)-12和12-3-12)水溶液中形成蠕虫状胶束及其性质的影响.在无盐状态下,50mmo·lL-1的12-3(OH)-12或12-3-12在水溶液中仅形成球状或棒状胶束.NaSal可促进上述两体系胶束的生长,生成蠕虫状胶束.比较而言,12-3(OH)-12对NaSal更敏感,可以在低盐浓度下生成蠕虫状胶束.而且与12-3-12体系相比,12-3(OH)-12生成了更长的蠕虫状胶束.这些差别在于12-3(OH)-12体系中存在羟基连接链之间的氢键作用,这增加了12-3(OH)-12头基的亲水性,促进了反离子的解离,增大的胶束表面电荷密度更强烈地结合水杨酸根反离子,减小了头基间的静电斥力,反过来又增强了分子间氢键,致使12-3(OH)-12胶束迅速生长.

鼻腔黏液纤毛传输系统功能的评估

黏液纤毛传输功能在呼吸道防卫系统中的作用举足轻重。对黏液纤毛传输系统功能的评估,根据评估对象的不同可分为三部分:对黏液纤毛传输系统功能的综合评估;对纤毛运动状况的评估;以及对黏液产量和理化性质的评估,临床评估的重点在前两部分。糖精试验简便易行,敏感和可靠,是目前综合评估黏液纤毛传输系统功能最常用的方法。对纤毛的评估可分为静态结构评估和动态功能评估两大类,前者主要采用扫描和透射电子显微镜观察,评估固定纤毛的超微结构,后者通过观察纤毛的运动速度和模式,评价其功能。上述鼻腔黏液纤毛传输系统功能评估的方法,构成了较为完整的评估体系,具备一定的临床实用价值。
