Introducción: La infección persistente por genotipos de virus papiloma humano de alto riesgo (VPH-AR) es la principal causa del cáncer cérvico-uterino en todo el mundo. Los genotipos 16 y 18 están asociados a la progresión hacia el cáncer de cuello uterino; sin embargo, otros genotipos también presentan alto riesgo oncogénico. Existe escasa evidencia respecto a la distribución de genotipos VPH-AR en la población nacional, siendo un tema que debiese ser abordado en el contexto de un creciente aumento de la inmigración e implementación del programa de inmunización en Chile desde 2015. Objetivo: Dar a conocer la distribución de genotipos de VPH-AR detectados en pacientes de ambos sexos, atendidos en la red de atención privada de Clínica Dávila de Santiago, entre los años 2014 y 2021. Metodología: Se estudiaron muestras genitales y anales provenientes de 3.642 pacientes, incluyendo ambos sexos. La genotipificación fue realizada mediante reacción de la polimerasa en cadena (RPC) en tiempo real (HPV AnyplexTM II HPV28 detection, Seegene, Korea. Resultados: La distribución global de genotipos en mujeres (porcentaje) fue: 16 (14,34%) - 31 (6,20%) - 39 (5,94%) - 58 (5,94%) - 51 (5,68%) - 53 (5,64%) - 52 (5,30%) - 56 (5,27%) - 68 (5,19%) - 66 (4,97% - 18 (3,36%) - 59 (3,29%) - 73 (2,80%) - 35 (2,54%) - 45 (2,13%) - 33 (1,53%) - 82 (1,38%) - 26 (0,49%) y 69 (0,41%). En hombres fue: 16 (8,52%) - 58 (4,39%) - 51 (8,44%) - 26 (0,42%) - 18 (3,21%) - 52 (4,47%) - 39 (5,40%) - 53 (4,56%) - 33 (1,69%) - 35 (2,03%), 73 (2,19%) - 69 (0,59%) - 45 (2,11%) - 59 (4,22%) - 68 (3,04%) - 66 (5,06%) - 31 (4,64%) - 56 (4,81%) y 82 (1,10%). Conclusiones: La distribución de los genotipos de VPH fue concordante con estudios previos nacionales. Se observó una tendencia a la reducción del genotipo 16 en el tiempo, lo cual podría relacionarse a la vacunación, implementada en los últimos años en Chile. Destaca que otros genotipos de VPH-AR tuvieron una alta frecuencia en la población estudiada por lo que sería recomendable evaluar la pesquisa ampliada de genotipos de VPH-AR para valorar el riesgo oncogénico, con fines diagnósticos y terapéuticos.
Background: Persistent infection by high-risk human papillomavirus (HR-HPV) genotypes is the main cause of cervical cancer worldwide. Genotypes 16 and 18 are associated with progression to cervical cancer, however other genotypes also present high oncogenic risk. There is little evidence regarding the distribution of HR-HPV genotypes in the national population, being an issue that should be addressed in the context of a growing increase in immigration and implementation of the immunization program in Chile since 2015. Aim: To show the distribution of HR-HPV genotypes detected in women and men, attended at the private care network of Clinica Davila, Santiago City, between 2014 and 2021. Methods: Genital and anal samples from 3,642 patients were studied, including both sexes. Genotyping was performed by real-time polymerase chain reaction (PCR) (HPV AnyplexTM II HPV28 detection, Seegene, Korea). Results: The global distribution of genotypes in women (percentage) was: 16 (14.34%) - 31 (6.20%) - 39 (5.94%) - 58 (5.94%) - 51 (5.68%) - 53 (5.64%) - 52 (5.30%) - 56 (5.27%) - 68 (5.19%) - 66 (4.97%) - 18 (3.36%) - 59 (3.29%) - 73 (2.80%) - 35 (2.54%) - 45 (2.13%) - 33 (1.53%) - 82 (1.38%) - 26 (0.49%) and 69 (0.41%). In men was: 16 (8.52%) - 58 (4.39%) - 51 (8.44%) - 26 (0.42%) - 18 (3.21%) - 52 (4.47%) - 39 (5.40%) - 53 (4.56%), 33 (1.69%) - 35 (2.03%) - 73 (2.19%) - 69 (0.59%) - 45 (2.11%) - 59 (4.22%) - 68 (3.04%) - 66 (5.06%) - 31 (4.64%) - 56 (4.81%) and 82 (1.10%). Conclusions: The distribution of HPV genotypes was consistent with previous national studies. A tendency to reduce genotype 16 over the years was observed, which could be related to the vaccination, implemented in recent years in Chile. It is remarkable that other HR-HPV genotypes had a high frequency in the population studied, so it would be advisable to evaluate an expanded screening for HR-HPV genotypes to assess the oncogenic risk, for diagnostic and therapeutic purposes.

ABSTRACT
@#Objective To analyze the related knowledge-attitude-practice(KAP)and the influencing factors of human papilloma virus(HPV)vaccine among 16 — 45 year old resident women in Pudong New Area.Methods Six of the 36streets(towns)in Pudong New Area were randomly selected as the survey site,the resident women aged 16 — 45 years were randomly selected excluding those with reading or comprehension disabilities and those with mental disorders,and a total of 1 022 valid questionnaires were collected through self-filling questionnaires to understand the KAP status of the HPV vaccine among the resident women in Pudong New Area. The relationship among KAP of HPV vaccine and its influencing factors were analyzed by univariate analysis and structural equation model.Results The overall awareness rate of HPV vaccine among 16-45 year old resident women in Pudong area was higher. Univariate analysis showed that marital status,educational level,employment status and household annual income were related to the awareness level of HPV vaccine(χ~2=12. 832,17. 636,16. 770 and 20. 030,respectively,each P < 0. 05);Age,marital status,employment status and children′s status were correlated with HPV vaccination level(χ~2= 12. 382,25. 777,8. 830 and 20. 138,respectively,each P <0. 05);HPV vaccine health education,HPV and HPV vaccine knowledge scores affected HPV vaccination status(χ~2=97. 561 and 68. 969,respectively,P < 0. 001);Subjects' knowledge of cervical cancer was positively affected by knowledge of HPV infection(γ_(11)= 0. 756,P < 0. 001). Knowledge of cervical cancer not only positively affected subjects′ attitudes towards the efficacy of HPV vaccine(β_(21)= 0. 557,P < 0. 001),also had a direct effect on the HPV vaccination behavior of the subjects,showing a promoting effect(β_(31)= 0. 274,P = 0. 004). Subjects′ approval of the efficacy of HPV vaccine had a positive effect on their actual vaccination behavior(β_(32)= 0. 175,P = 0. 016).Conclusion The willingness of the 16 — 45 year old resident women in Pudong New Area to inoculate HPV vaccine was positive,but the actual vaccination rate was low. It is suggested to strengthen the HPV vaccine publicity while strengthening the education of cervical cancer and HPV infection,and consider the necessity of including the suitable age males in the scope of human vaccination.
ABSTRACT
Accessory spleen refers to the spleen tissue that exists outside of the normal spleen, with a similar structure to the main spleen and certain functions. Intrapancreatic accessory spleen (IPAS) completely enveloped by the pancreas has an incidence rate of only 2%, and it is easily misdiagnosed in clinical practice due to its atypical clinical symptoms and similar radiological features to pancreatic neuroendocrine tumor, pancreatic solid pseudopapillary tumor, and other pancreatic space-occupying lesions. This article reports the clinical data of two patients with IPAS who were misdiagnosed as pancreatic neuroendocrine tumor and pancreatic solid pseudopapillary tumor, respectively, analyzes the reasons for misdiagnosis, and summarizes the experience in diagnosis and treatment, in order to improve the ability for the differential diagnosis of IPAS in clinical practice.
ABSTRACT
Abstract Choroid plexus papillomas (CPPs) are rare benign neoplasms which are particularly uncommon in the posterior fossa in children. We herein present a case series of five patients treated at a tertiary care hospital. A comprehensive literature review was also carried out. The patients treated at the tertiary care hospital were aged between 4 and 16 years. Gross total resection (GTR) was initially achieved in two patients. All patients showed clinical improvement. Moreover, 27 articles published between 1975 and 2021 were selected for the literature review, totaling 46 patients; with the 5 patients previously described, the total sample was composed of 51 cases, With a mean age was 8.2 years. The lesions were located either in the fourth ventricle (65.3%) or the cerebellopontine angle (34.7%). Hydrocephalus was present preoperatively in 66.7% of the patients, and a permanent shunt was required in 31.6% of the cases. The GTR procedure was feasible in 64.5%, and 93.8% showed clinical improvement. For CPPs, GTR is the gold standard treatment and should be attempted whenever feasible, especially because the role of the adjuvant treatment remains controversial. Neuromonitoring is a valuable tool to achieve maximal safe resection. Hydrocephalus is common and must be recognized and promptly treated. Most patients will need a permanent shunt. Though there is still controversy on its efficacy, endoscopic third ventriculostomy is a safe procedure, and was the authors' first choice to treat hydrocephalus.
Resumo Os papilomas do plexo coroide (PPCs) são neoplasias benignas raras e, na população pediátrica, são particularmente incomuns na fossa posterior. Apresentamos uma série de casos de cinco pacientes atendidos em um hospital terciário. Além disso, foi realizada uma ampla revisão da literatura. Os pacientes atendidos no hospital terciário tinham entre 4 e 16 anos. Ressecção macroscópica total (RMT) foi inicialmente realizada em dois pacientes. Todos os pacientes apresentaram melhora clínica. Além disso, 27 artigos publicados entre 1975 e 2021 foram selecionados para a revisão da literatura, totalizando 46 pacientes. Somados à série de casos atuais, encontramos 51 pacientes, com média de idade de 8,2 anos. As lesões localizavam-se no quarto ventrículo (65,3%) ou no ângulo pontocerebelar (34,7%). Hidrocefalia estava presente no pré-operatório em 66,7% dos pacientes, e derivação ventricular permanente foi necessária em 31,6% dos casos. A RMT foi possível em 64,5%, e 93,8% tiveram melhora clínica. Para os CPPs, a RMT é o tratamento padrão-ouro e deve ser tentado sempre que possível, especialmente porque ainda existem controvérsias quanto ao papel do tratamento adjuvante. A neuromonitorização é uma ferramenta importante para se atingir a máxima ressecção segura. A hidrocefalia é comumente vista nesses pacientes e deve ser identificada e tratada. A maioria dos pacientes irá precisar de uma derivação permanente. Apesar de persistirem controvérsias sobre sua eficácia, a terceiro-ventriculostomia endoscópica foi a primeira escolha para tratar a hidrocefalia na experiência dos autores e é uma opção segura.
ABSTRACT
Human papillomavirus (HPV) infection is one of the most common sexually transmitted viral diseases. A descriptive cross-sectional study was conducted with the purpose of clinically and epidemiologically characterizing anal HPV infection in patients who attended the Benign Orificial Pathology Consultation of the Coloproctological Unit at the Dr. "Antonio María Pineda" Central University Hospital, during the period March 2022 -February 2023, by selecting 288 patients whose average age was 47.09 ± 14.61 years, being the 41-50 years old group (29.17%) and the 51-60 years old group (19.44%) the most affected groups by pathologies of the anal region, with a predominance of male (54.17%). The sociodemographic characteristics with the highest frequency included married (48.61%) and single (47.22%); secondary level of education (44.44%) and traders (18.05%) and housewives (15, 28%) as predominant occupations. The risk factors were represented by onset of sexual intercourse between 16-20 years of age (65.28%), heterosexuality (91.67%), 22.22% reported having anal sex and 5.56% oral sex. Likewise, 5.56% were reported with a history of genital HPV and 4.17% were HIV positive. In addition, 48.61% stated not to use condoms. The initial clinical diagnosis included hemorrhoidal disease (30.55%), anal fistula (25%) and anal fissure (18.05%), and one patient (1.39%) with anal HPV infection. Anal cytology results showed 8.33% flat epithelial cells with cytopathic changes suggestive of HPV infection and 1.39% squamous cells with cytopathic changes suggestive of HPV infection: 50% mild inflammatory negative for malignancy and 33.33% flat epithelial cells without atypia. In conclusion, the anal cytology investigation should continue to determine the actual frequency of anal HPV infection. (AU)

Background: Syringocystadenoma papilliferum is a benign adnexal neoplasm. Contiguous squamous proliferation has been rarely described in syringocystadenoma papilliferum. Aims: This study aimed to evaluate the spectrum and pathogenesis of contiguous squamous proliferation in syringocystadenoma papilliferum. Materials and Methods: All cases of syringocystadenoma papilliferum diagnosed over the past 12 years were screened for contiguous squamous proliferation. Cases with associated nevus sebaceous were excluded from the study. Immunohistochemistry for GATA3, CK7, BRAFV600E and p16 was performed. PCR for human papilloma virus, type 16 and 18, was carried out. Results: Of a total of 30 cases, 14 cases showed associated contiguous squamous proliferation which included four cases of verrucous hyperplasia, six cases with papillomatosis, two cases with mild squamous hyperplasia and one case each of Bowen’s disease and squamous cell carcinoma. In the cases with non-neoplastic contiguous squamous proliferations, the squamous component did not express CK7 or GATA3. However, the squamous component of premalignant and malignant lesions expressed CK7 and GATA3 concordant with the adenomatous component. BRAF was positive in adenomatous component in five cases while the contiguous squamous proliferation component was negative for BRAF in all but one case. p16 was negative in both components of all cases and PCR for human papilloma virus was negative in all cases. Limitations: Due to the rarity of disease, the sample size of our study was relatively small with two cases in the 2nd group, that is, syringocystadenoma papilliferum with malignant contiguous squamous proliferation. Detailed molecular studies such as gene sequencing were not performed. Conclusion: Syringocystadenoma papilliferum with contiguous squamous proliferation is underreported, and most commonly displays verrucous hyperplasia. The premalignant and malignant contiguous squamous proliferations likely arise from syringocystadenoma papilliferum while the hyperplastic contiguous squamous proliferations likely arise from the adjacent epidermis. Relationship with high-risk human papilloma virus is unlikely. However, further molecular analysis of larger number of cases is required to establish the pathogenesis.
ABSTRACT
Atypical choroid plexus papilloma is classified as WHO (World Health Organization) Grade II subtype of choroid plexus tumor, and it has intermediate pathological features, prognosis, and clinical outcome rates between choroid plexus papilloma and choroid plexus carcinoma. These tumors are more common in children compared with adults and are usually located in the lateral ventricles. We present a case of an adult with atypical choroid plexus papilloma located in the infratentorial region. A 41?year?old woman underwent evaluation for headache and dull aching neck pain. Magnetic resonance imaging (MRI) of the brain revealed a well?defined intraventricular mass lesion in the fourth ventricle and foramen of Luschka. She underwent craniotomy and gross total excision of the lesion. Histopathological and immunohistochemical findings confirmed the diagnosis of atypical choroid plexus papilloma (WHO Grade II). We discuss the various treatment options for this condition and review the relevant literature.
ABSTRACT
Bladder cancer is one of the leading malignancies in the world associated with signi?cant morbidity and mortality. About 80% of a bladder cancer is urothelial variant, remaining 20% will have a divergent histological presentation. The pathophysiological study of these variants has recently increased because the therapeutic approach is not uniform for all variants. These variants have important diagnostic, prognostic and therapeutic implications. A molecular and genetic study of these variants will allow them to be better de?ned. Here we present four cases of Histological variants of bladder tumors with varying presentations in the department of urology, Madurai medical college, which is studied over the period of one year (2022-2023).
ABSTRACT
Introducción: Los condilomas o verrugas anogenitales son secundarios a una infección causada por el virus del papiloma humano en sitios específicos, como la piel de la región anogenital, en las mucosas vaginal y anal. Es una infección de transmisión sexual rara en la edad pediátrica, muy frecuente entre los adultos y adolescentes sexualmente activos; la causa en los infantes, sin descartar el abuso sexual podría ser: 1. En el momento del parto, en la etapa neonatal y durante los primeros años; 2. Autoinoculación o hetero-inoculación de los genitales de otros niños, de adultos, familiares como la madre o cuidadores. Podría manifestarse como pequeños papilomas o crecimientos verrugosos en la piel anogenital, en la mucosa de la vagina o el ano. Este caso tiene importancia clínica ya que los tratamientos convencionales presentan recidivas a corto plazo y muchos de ellos no son bien tolerados por los pequeños pacientes. Hay tratamientos agresivos como la criocirugía; el uso de medicamentos costosos como el Imiquimod; sin embargo, las reci-divas son muy frecuentes con estos tratamientos convencionales.Objetivo: Describir el uso de un esquema de terapia de tratamiento con podofilina en combina-ción con ácido glicirricínico y ácido tricloroacético, en una paciente pediátrica con diagnóstico de condiloma ano-perineal, para ayudar a disminuir las recidivas, los costos y sobre todo los efectos psicológicos que provocan los métodos dolorosos en los pequeños pacientes. Presentación del caso: Paciente que presentó lesiones verrucosas, puntiagudos en la región ano-perineal; y, luego de haber sido intervenida en un centro de salud por varios días mediante la topicación sobre las lesiones una solución de ácido tricloro acético a 5% combinada con podofi-lina al 50%; sin embargo, el cuadro se exacerbó extendiéndose las lesiones hasta cerca del área genital. Luego de lo cual acudió a nuestra consulta, donde además de la combinación anterior, más la adición de ácido glicirricinico tópico y logrando a los 30 días la remisión de las lesiones.Conclusiones y recomendaciones: La combinación de una sustancia corrosiva, el ácido tricloro acético, con una sustancia que detiene la multiplicación celular como la podofilina; y el ácido glicirricinico el cual disminuye la replicación de los virus en un estadio temprano, impide la salida del virión de su cápside y con esto su penetración a las células. La aplicación de esta triple terapia mejoró los resultados para condilomatosis en pacientes pediátricos.
Introduction: Anogenital condylomas or warts are secondary to an infection caused by the human papillomavirus in specific sites, such as the skin of the anogenital region, in the vaginal and anal mucosa. It is a rare sexually transmitted infection in pediatric age, very common among sexually active adults and adolescents; The cause in infants, without ruling out sexual abuse, could be: 1. At the time of birth, in the neonatal stage and during the first years; 2. Autoinoculation or he-tero-inoculation of the genitals of other children, adults, family members such as the mother or caregivers. It could manifest as small papillomas or warty growths on the anogenital skin, on the mucosa of the vagina or anus. This case has clinical importance since conventional treatments present short-term recurrences and many of them are not well tolerated by young patients. There are aggressive treatments such as cryosurgery; the use of expensive medications such as Imiqui-mod; However, recurrences are very common with these conventional treatments.Objective: To describe the use of a treatment regimen with podophyllin in combination with glycyrr-hizinic acid and trichloroacetic acid, in a pediatric patient diagnosed with anoperineal condyloma, to help reduce recurrences, costs and, above all, psychological effects. that painful methods cause in young patients.Case presentation: The patient presents sharp, verrucous lesions in the ano-perineal region; and, after having been operated on in a health center for several days by topicalizing a 5% trichloroace-tic acid solution combined with 50% podophyllin on the lesions; However, the condition worsened, with the lesions extending close to the genital area. After which he came to our consultation, where in addition to the previous combination, plus the addition of topical glycyrrhizinic acid and achie-ving remission of the lesions after 30 days.Conclusions and recomendations: The combination of a corrosive substance, trichloroacetic acid, with a substance that stops cell multiplication such as podophyllin; and glycyrrhizinic acid, which decreases virus replication at an early stage, prevents the release of the virion from its cap-sid and thus its penetration into the cells. The application of this triple therapy improved the results for condylomatosis in pediatric patients.

La papilomatosis respiratoria recurrente es una enfermedad neoplásica causada por el virus del papiloma humano y caracterizada por el crecimiento de lesiones proliferativas exofíticas que afectan la mucosa de las vías respiratorias. En su epidemiología se presenta una distribución bimodal, con una forma juvenil en menores de 20 años, más agresiva, con múltiples lesiones papilomatosas y alta frecuencia de recurrencia, en comparación con la forma adulta. El compromiso pulmonar es poco frecuente y su manejo es un desafío. Se presenta el caso de un varón de 13 años con antecedente de papilomatosis laríngea desde los dos años. El paciente mostró dificultad respiratoria y múltiples nódulos estenosantes en laringe y tráquea, y varios quistes pulmonares visualizados en la tomografía de tórax. Se le realizó exéresis de las lesiones papilomatosas y traqueostomía. Recibió dosis única de bevacizumab 400 mg intravenoso y terapias respiratorias con evolución favorable, sin recurrencias en el seguimiento.
Recurrent respiratory papillomatosis is a neoplastic disease caused by the human papillomavirus and characterized by the growth of exophytic proliferative lesions affecting the mucosa of the respiratory tract. This condition has a bimodal age distribution; the juvenile form affects those under 20 years of age, is more aggressive and presents multiple papillomatous lesions and high frequency of recurrence, compared to the adult form. Pulmonary involvement is rare and challenging to treat. We present the case of a 13-year-old male with a history of laryngeal papillomatosis since the age of two years. The patient showed respiratory distress and multiple stenosing nodules in the larynx and trachea, as well as several pulmonary cysts identified on chest CT. The patient underwent excision of the papillomatous lesions and tracheostomy. Then, the patient received a single dose of intravenous bevacizumab 400 mg and respiratory therapies with favorable evolution, without recurrences during follow-up.

Objective:To explore the effects of Onodera′s prognostic nutritional index (PNI) on the prognosis of locally advanced oropharyngeal squamous cell carcinoma (LA-OPSCC) after induction chemotherapy followed by sequential chemoradiotherapy.Methods:A retrospective analysis was conducted on the clinical data of 52 LA-OPSCC patients receiving induction chemotherapy followed by sequential chemoradiotherapy in The Affiliated Cancer Hospital of Guizhou Medical University during 2014-2018. The PNI values of all the patients at different treatment phases were statistically analyzed, and the ROC curve was employed to determine the optimal critical value of PNI. The patients in this study were divided into a well-nourished group ( n = 27) and a poorly-nourished group ( n = 25). The Kaplan-Meier method was used for survival analysis. The Cox proportional hazards model was utilized to analyze the relationships between different nutritional status and prognosis. Clinical features and adverse reactions were compared between the two groups. Results:The PNI values decreased significantly after radiotherapy, with an optimal critical value of 42.4. The 5-year overall survival (OS) and progression-free survival (PFS) of the well-nourished group (PNI ≥ 42.4) were 62.6% and 60.9%, respectively, which were significantly higher than those (30.1% and 29.7%) of the poorly-nourished group (PNI < 42.4, χ2 = 11.12, 5.74, P < 0.05). The multivariate analysis showed that PNI was an independent prognostic factor for the OS after radiotherapy ( HR = 2.752, 95% CI: 1.095-6.917, P = 0.031). The LA-OPSCC patients aged over 60 years or those who did not respond to induction chemotherapy accounted for a higher proportion of malnutrition after chemoradiotherapy ( χ2 = 4.89, 5.05, P < 0.05). Conclusions:PNI after radiotherapy can be used as a prognostic factor in the evaluation of LA-OPSCC patients receiving induction chemotherapy followed by sequential chemoradiotherapy. The LA-OPSCC patients aged over 60 years or those who do not respond to induction chemotherapy should receive more nutritional support during the chemoradiotherapy.
ABSTRACT
Objective@#To explore the value of T2WI and enhanced T1WI magnetic resonance imaging models in differentiating inverted papilloma and polyp of nasal cavity and paranasal sinus.@*Methods@#54 cases of inverted papilloma (NIP) and 51 cases of polyp ( NP) with complete T2WI and enhanced T1WI images confirmed by pathology were collected.ITK snap was used to outline all levels of the lesion.Pyromics was used to extract image omics features.Firstly,the mRMR) was used for feature extraction,and then rfe-SVM was used to remove the feature of minimum score and establish a prediction model.The sensitivity and specificity of ROC curve were used to evaluate the performance of the model,and were verified in the validation set. @*Results@# A total of 1 133 image omics features were extracted,and 30 features were retained after mrmr dimensionality reduction for the establishment of prediction models.The AUC value of T1WI enhanced prediction model was : training set 0. 98,validation set 0. 95,the sensitivity and specificity of training set were 89. 7% and 100% respectively,and the sensitivity and specificity of validation set were 93. 8% and 93. 3% respectively.The AUC value of T2WI prediction model was : training set 0. 95,validation set 0. 91,the sensitivity and specificity of training set were 82. 1% and 95. 6% respectively,and the sensitivity and specificity of validation set were 93. 8% and 84. 2% respectively.@*Conclusion@#MRI based on T1WI enhancement prediction model and T2WI prediction model have certain value in differentiating inverted papilloma and polyp of nasal cavity and paranasal sinus.
ABSTRACT
Sinonasal inverted papilloma(SNIP) is a kind of benign tumor originating from the nasal cavity and paranasal sinuses, accounting for 70% of papillomas. The incidence of the disease is more common in males, with an average age of 50-60 years. It is most likely to occur in unilateral maxillary sinus and ethmoid sinus, followed by sphenoid sinus and frontal sinus.It has the characteristics of local invasion, high recurrence rate and malignant tendency, and most malignant transformation into squamous cell carcinoma. Endoscopic nasal resection and appropriate adjuvant therapy can help to reduce the recurrence rate and inhibit further deterioration. We report the results of a 10-year follow-up of a SNIP patient, including the clinical manifestations, recurrence course and treatment plan during the 10 years. The patient underwent multiple nasal endoscopic surgeries, and had a recurrence of multiple focal attachment pattern, and finally had direct invasion and distant metastasis. Tumor recurrence and further deterioration persisted despite the use of a comprehensive treatment.

Objective@#To investigate the awareness of human papillomavirus (HPV) vaccine knowledge among women in Hainan Province and the willingness to receive HPV vaccination among women and their daughters, so as to provide insights into HPV vaccine promotion and cervical cancer control. @*Methods@#Women aged 20 to 64 years who participated in the cervical cancer screening program in Hainan Province from July 2021 to February 2022 were enrolled, and participants' demographics, awareness of knowledge about HPV vaccine, and willingness to receive HPV vaccination among themselves and their daughters using a questionnaire survey. The factors affecting willingness to receive HPV vaccination were identified using a multivariable logistic regression model.@*Results@#A total of 4 300 questionnaires were allocated and 4 023 valid questionnaires were recovered, with an effective recovery rate of 93.56%. The respondents had a mean age of (35.52±6.48) years, and their daughters had a mean age of (8.93±4.83) years. There were 826 participants knowing HPV vaccine-related knowledge, with an awareness rate of 20.35%. The proportions of willingness to receive HPV vaccination were 75.07% among respondents and 71.36% among their daughters. Multivariable logistic regression analysis identified age (20 to <30 years, OR=1.474, 95%CI: 1.167-1.862; 30 to <40 years, OR=1.455, 95%CI: 1.199-1.765), urban-registered residence (OR=1.251, 95%CI: 1.016-1.541), monthly household income (3 000 to <5 000 Yuan, OR=1.568, 95%CI: 1.314-1.873; 5 000 Yuan and more, OR=1.231, 95%CI: 1.014-1.496), affordable fees for a single dose of HPV vaccination (100 to <500 Yuan, OR=1.358, 95%CI: 1.159-1.590; 500 Yuan and higher, OR=1.609, 95%CI: 1.188-2.180), and awareness of HPV vaccine-related knowledge (OR=4.473, 95%CI: 3.416-5.855) as factors affecting respondents' willingness to receive HPV vaccination, and participation in New Rural Cooperative Medical Insurance (OR=1.652, 95%CI: 1.087-2.511), affordable fees for a single dose of HPV vaccination (100 to <500 Yuan, OR=1.905, 95%CI: 1.633-2.221; 500 Yuan and higher, OR=1.683, 95%CI: 1.275-2.223), awareness of HPV vaccine-related knowledge (OR=3.625, 95%CI: 2.847-4.615), daughter's active request for HPV vaccination (OR=1.695, 95%CI: 1.293-2.222), and frequency of sexual health education for daughters (frequently, OR=2.142, 95%CI: 1.789-2.564; occasionally, OR=1.707, 95%CI: 1.416-2.059) as factors affecting the willingness to receive HPV vaccination among respondents' daughters. @*Conclusions@#The awareness of HPV vaccine-related knowledge is low among women aged 20 to 64 years in Hainan Province, and the women's and their daughters' willingness to receive HPV vaccination is associated with age, household registration, economic level, price of HPV vaccine and awareness of HPV vaccine-related knowledge.
