RESUMO
The Bos Taurus Papillomavirus, commonly known as bovine papillomavirus (BPV), can cause lesions in the mucosa of the gastrointestinal tract (GIT) in cattle and induce the formation of papillomas in organs such as the pharynx, esophagus, rumen and reticulum. GIT papillomas can lead to feeding and breathing distress. Moreover, the sample collection is challenging, which reduces the BPV diagnosis in these organs. BPV can cause exophytic nodular, cauliflower-like, flat, filiform or atypical-shape papillomas at the epidermis. Histologically, the papillomas demonstrate orthokeratotic/parakeratotic hyperkeratosis and koilocytosis and, currently, BPV comprises 45 described types. The aim of this study was to carry out the genetic characterization of BPV present in rumen neoplastic lesions of cattle raised extensively in the Western Amazon region, Brazil. A total of 100 papillomatous ruminal samples were collected from animals slaughtered in Ji-Paraná and Urupá municipalities from the Rondônia state, Brazil. The samples were submitted to PCR using the primer pair FAP59/FAP64 and sequenced by the Sanger method. Histopathological analysis was performed on 24 samples, which had enough material for this purpose. As a result, samples were histologically classified as fibropapilloma and squamous papilloma. Among the samples analyzed, it was possible to identify the BPVs 2, 13 (Delta PVs) and 44, with one sample classified as a putative new subtype of BPV44. The present study could identify BPV13 and 44 types in cattle rumen tissues from the Brazilian Amazon region for the first time.
RESUMO
OBJECTIVES: Exophytic Sinonasal Papilloma (ESP) is a benign tumor of the sinonasal tract. Complete surgical excision by endoscopic surgery is the treatment of choice. However, a high recurrence rate (36% at 5-year follow-up) is associated with this method, which may indicate the presence of microorganisms such as Human Papillomavirus (HPV). It is important to note that the standard treatment for ESP does not include antiviral drugs. In our study, we are testing the effectiveness of an interferon-containing drug in reducing recurrence and postoperative reactions in patients with ESP. METHODS: We included 78 patients aged 23-83 years with a confirmed diagnosis of ESP by rhinoscopy and nasal endoscopy and a positive PCR test for HPV in nasal scrapings. To compare the results, we divided the patients into main and control groups. The main group received recombinant human interferon after surgery, while the control group did not receive the drug. We performed a statistical analysis to compare the proportion of patients without reactive manifestations at different stages of the postoperative period, as well as to compare the proportion of patients with recurrent ESP at certain stages of observation. RESULTS: The introduction of recombinant human interferon accelerated the resolution of postoperative reactions and promoted the healing of the nasal mucosa after surgical removal of the ESP. We also found a statistically significant association between treatment with recombinant interferon and a reduction in the recurrence rate of ESP. CONCLUSION: According to the results of the study, it was found that in the main group of patients who received rhIFN-α2b (recombinant human Interferon alpha 2b) in the postoperative period, the frequency of relapses of ESP and the time of postoperative recovery were significantly lower than in patients in the control group who did not take the drug. LEVEL OF EVIDENCE: Cohort Study.

Introduction: Squamous cell papilloma is a benign tumor whose pathogenesis is generally related to the human papillomavirus. Despite affecting several organs, we did not find cases reported in the nails. Case Presentation: A 67-year-old female presented with a painful lesion in the nail of the right hallux that started in 2021, with an erythematous appearance evolving to black and expansive growth. Due to the evolution and symptoms, she opted for excision, with a histopathological report of squamous cell papilloma. Complementary treatment with imiquimod was performed, with good healing and pain control. Discussion: Due to the lack of previous reports, treatment was based on therapeutic options for papillomas located in other regions. Excision was performed, followed by application of imiquimod with good response. The prognosis is favorable; however, further studies are needed to elucidate the diagnosis and management of nail squamous cell papilloma.
RESUMO
En 1871, el cirujano Johann von Mikulicz Radecki, de la Universidad de Viena en Austria, introdujo por primera vez la descripción del papiloma escamoso; finalmente en 2002, se reclasificó como una familia independiente con un total de 29 genes, de los cuales cinco se asocian al papiloma humano. En 2021, el Centro Internacional de Referencia del Virus del Papiloma Humano del Instituto Karolinska reportó un total de 228 diferentes tipos de VPH (AU)

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.

BACKGROUND: Many low- and-middle-income countries are disproportionately burdened by cervical cancer, resulting in high morbidity and mortality. HPV-DNA testing coupled with treatment with thermal ablation is a recommended screening and precancer treatment strategy, but not enough is known about how this can be effectively implemented in the context of integrated services. The (Scale Up Cervical Cancer Elimination by Secondary prevention Strategy, (SUCCESS) project is conducting a study to understand this approach, integrated into existing women's health services in Burkina Faso, Cote d'Ivoire, Guatemala, and the Philippines (2020-2024). METHODS: A hybrid effectiveness-implementation type III mixed-methods observational study design is used to assess feasibility, acceptability, and costs of integrated service delivery in 10 sites per country, selected considering urban/rural location, facility level, onsite/offsite laboratories, and health services type. In each country, a sample size of 2227 women aged 25-49 years will be enrolled with about 20% being women living with HIV. The primary outcome is proportion of HPV positive women completing precancer treatment, if eligible, within three months of screening. Data collection and analysis includes; facility and client exit surveys, key informant and client interviews, registries and project records extractions, and costing data analysis. Analysis includes descriptive statistics, context description, thematic analysis, and document analysis. Quantitative analyses will be stratified by participant's HIV status. DISCUSSION: Recruitment of study participants started in April 2022 (Burkina Faso and Côte d'Ivoire) and August 2022 (Guatemala and the Philippines). Enrolment targets for women screened, client exit, in-depth and key informant interviews conducted were reached in Burkina Faso and Cote d'Ivoire in November 2022. Guatemala and Philippines are expected to complete enrolment by June 2023. Follow-up of study Participants 12-months post-treatment is ongoing and is expected to be completed for all countries by August 2024. In LMICs, integrating cervical cancer secondary prevention services into other health services will likely require specific rather than incidental recruitment of women for screening. Reconfiguration of laboratory infrastructure and planning for sample management must be made well in advance to meet induced demand for screening. Trail Registration ClinicalTrials.Gov ID: NCT05133661 (24/11/2021).

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.
RESUMO
The cervicovaginal microbiota is influenced by host physiology, immunology, lifestyle, and ethnicity. We hypothesized that there would be differences in the cervicovaginal microbiota among pregnant, nonpregnant, and menopausal women living in Puerto Rico (PR) with and without human papillomavirus (HPV) infection and cervical cancer. We specifically wanted to determine if the microbiota is associated with variations in cervical cytology. A total of 294 women, including reproductive-age nonpregnant (N = 196), pregnant (N = 37), and menopausal (N = 61) women, were enrolled. The cervicovaginal bacteria were characterized by 16S rRNA amplicon sequencing, the HPV was genotyped with SPF10-LiPA, and cervical cytology was quantified. High-risk HPV (HR-HPV, 67.3%) was prevalent, including genotypes not covered by the 9vt HPV vaccine. Cervical lesions (34%) were also common. The cervical microbiota was dominated by Lactobacillus iners. Pregnant women in the second and third trimesters exhibited a decrease in diversity and abundance of microbes associated with bacterial vaginosis. Women in menopause had greater alpha diversity, a greater proportion of facultative and strictly anaerobic bacteria, and higher cervicovaginal pH than premenopausal women. Cervical lesions were associated with greater alpha diversity. However, no significant associations between the microbiota and HPV infection (HR or LR-HPV types) were found. The cervicovaginal microbiota of women living in Puerto Rican were either dominated by L. iners or diverse microbial communities regardless of a woman's physiological stage. We postulate that the microbiota and the high prevalence of HR-HPV increase the risk of cervical lesions among women living in PR. IMPORTANCE In the enclosed manuscript, we provide the first in-depth characterization of the cervicovaginal microbiota of Hispanic women living in Puerto Rico (PR), using a 16S rRNA approach, and include women of different physiological stages. Surprisingly we found that high-risk HPV was ubiquitous with a prevalence of 67.3%, including types not covered by the 9vt HPV vaccine. We also found highly diverse microbial communities across women groups-with a reduction in pregnant women, but dominated by nonoptimal Lactobacillus iners. Additionally, we found vaginosis-associated bacteria as Dialister spp., Gardnerella spp., Clostridium, or Prevotella among most women. We believe this is a relevant and timely article expanding knowledge on the cervicovaginal microbiome of PR women, where we postulate that these highly diverse communities are conducive to cervical disease.

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)

Human Papillomavirus (HPV) infection is associated with intraepithelial neoplasia and cervical cancer (CC). Ecuador has a high prevalence of cervical cancer, with more than 1600 new cases diagnosed annually. This study aimed to analyze oncogenes E6 and E7 of HPV16 in samples collected from women with cancerous and precancerous cervical lesions from the Ecuadorian coast. Twenty-nine women, including six with ASCUS, three with LSIL, thirteen with HSIL, and seven with Cacu, were analyzed. The most common SNPs were E6 350G or L83V (82.6%) and E6 145T/286A/289G/335T/350G or Q14H/F78Y/L83V (17.4%). Both variants are reported to be associated with an increased risk of cervical cancer in worldwide studies. In contrast, all E7 genes have conserved amino-acid positions. Phylogenetic trees showed the circulation of the D (26.1%) and A (73.9) lineages. The frequency of D was higher than that reported in other comparable studies in Ecuador and Latin America, and may be related to the ethnic composition of the studied populations. This study contributes to the characterization of the potential risk factors for cervical carcinogenesis associated with Ecuadorian women infected with HPV16.

The relationship among microbiome, immunity and cervical cancer has been targeted by several studies, yet many questions remain unanswered. We characterized herein the virome and bacteriome from cervical samples and correlated these findings with innate immunity gene expression in a Brazilian convenience sample of HPV-infected (HPV+) and uninfected (HPV-) women. For this purpose, innate immune gene expression data were correlated to metagenomic information. Correlation analysis showed that interferon (IFN) is able to differentially modulate pattern recognition receptors (PRRs) expression based on HPV status. Virome analysis indicated that HPV infection correlates to the presence of Anellovirus (AV) and seven complete HPV genomes were assembled. Bacteriome results unveiled that vaginal community state types (CST) distribution was independent of HPV or AV status, although bacterial phyla distribution differed between groups. Furthermore, TLR3 and IFNαR2 levels were higher in the Lactobacillus no iners-dominated mucosa and we detected correlations among RIG-like receptors (RLR) associated genes and abundance of specific anaerobic bacteria. Collectively, our data show an intriguing connection between HPV and AV infections that could foster cervical cancer development. Besides that, TLR3 and IFNαR2 seem to create a protective milieu in healthy cervical mucosa (L. no iners-dominated), and RLRs, known to recognize viral RNA, were correlated to anaerobic bacteria suggesting that they might be related to dysbiosis.

BACKGROUND & AIMS: Perianal fistulizing Crohn's disease is the main risk factor for anal cancer in patients with inflammatory bowel disease. Whether this occurs due to a higher frequency of human papillomavirus remains unclear. The authors aimed to evaluate the prevalence of HPV and high-risk HPV in patients with perianal Crohn's disease, compared with a control group. METHODS: The authors conducted a two-center cross-sectional study in which perianal fistulizing Crohn's disease patients were matched for age and sex with patients with anorectal fistula without Crohn's disease. Biopsy specimens were obtained from fistulous tracts during examination under anesthesia for both groups. The samples were sent for HPV detection and genotyping using the INNO-LiPA test. RESULTS: A total of 108 subjects (54 in each group) were recruited. The perianal fistulizing Crohn's disease group showed a statistically higher frequency of HPV in the fistulous tract than the control group (33.3% vs. 16.7%; p = 0.046). Separate analyses on high-risk types demonstrated that there was a numerically higher frequency of HPV in the perianal fistulizing Crohn's disease group. In multiple logistic regression, patients with perianal fistulizing Crohn's disease were found to have a chance of HPV 3.29 times higher than patients without Crohn's disease (OR = 3.29; 95% CI 1.20â9.01), regardless of other variables. The types most frequently identified in the perianal fistulizing Crohn's disease group were HPV 11 (12.96%) and HPV 16 (9.26%). CONCLUSION: Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV than in patients with anorectal fistula without Crohn's disease.

The human papilloma virus (HPV) is the most common sexually transmitted infection, affecting nearly 50% of the world population. HPV can lead to tissue damage and is associated with many types of cancers. Healthcare professionals' knowledge regarding HPV infection are essential in assuring favorable outcomes for those exposed to HPV, either in prevention or in intervention efforts. In this cross-sectional, population-based study, we explored the levels of HPV knowledge among health professionals in a Brazilian municipality. In total, 260 individuals (90% women), aged 21-66 years (Mean = 40.10 ± 9.30) participated in this investigation and responded to standard questionnaires measuring HPV knowledge as well as sociodemographic and occupational data. Regarding HPV knowledge, 85 (32.8%) individuals were considered to have sufficient knowledge (scored good or very good according to percentile classifications), whereas 174 (67.2%) were labeled as having insufficient knowledge. Mann-Whitney tests showed higher HPV knowledge among those who reported not having children (p = 0.05) and lower levels in the group of community health workers (CHW; p < 0.001). Logistic regression analyses showed that having children (OR = 0.50; 95%CI: 0.26, 0.96) and being a CHW (OR = 0.52; 95%CI: 0.28, 0.97) were independently associated with insufficient knowledge about HPV. In conclusion, data reported in this study might aid in understanding factors associated with HPV management given the evidence collected from healthcare professionals, suggesting strategies to promote both health education and promotion.

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.

Abstract Background & Aims Perianal fistulizing Crohn's disease is the main risk factor for anal cancer in patients with inflammatory bowel disease. Whether this occurs due to a higher frequency of human papillomavirus remains unclear. The authors aimed to evaluate the prevalence of HPV and high-risk HPV in patients with perianal Crohn's disease, compared with a control group. Methods The authors conducted a two-center cross-sectional study in which perianal fistulizing Crohn's disease patients were matched for age and sex with patients with anorectal fistula without Crohn's disease. Biopsy specimens were obtained from fistulous tracts during examination under anesthesia for both groups. The samples were sent for HPV detection and genotyping using the INNO-LiPA test. Results A total of 108 subjects (54 in each group) were recruited. The perianal fistulizing Crohn's disease group showed a statistically higher frequency of HPV in the fistulous tract than the control group (33.3% vs. 16.7%; p = 0.046). Separate analyses on high-risk types demonstrated that there was a numerically higher frequency of HPV in the perianal fistulizing Crohn's disease group. In multiple logistic regression, patients with perianal fistulizing Crohn's disease were found to have a chance of HPV 3.29 times higher than patients without Crohn's disease (OR = 3.29; 95% CI 1.20‒9.01), regardless of other variables. The types most frequently identified in the perianal fistulizing Crohn's disease group were HPV 11 (12.96%) and HPV 16 (9.26%). Conclusion Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV than in patients with anorectal fistula without Crohn's disease.
RESUMO
Objetivo: nuestro objetivo principal fue evaluar la prevalencia de citología anal patológica en mujeres con antecedentes de neoplasia intraepitelial cervical. Métodos: se trata de un estudio de cohorte transversal desde mayo de 2018 a agosto de 2020 en el Centro Hospitalario Pereira Rossell. Se estudiaron dos cohortes: una de mujeres que tenían diagnóstico de neoplasia intraepitelial cervical y otra de control de mujeres sanas que asistieron al control, con una proporción de 2:1. Se calculó un tamaño muestral total de 205 pacientes, siendo 135 pacientes con NIC con un IC del 95%, suponiendo una prevalencia del 10% de lesiones preneoplásicas anales. El tamaño muestral de la cohorte control fue de 70 pacientes según la relación preestablecida. Resultados: se encontró asociación entre la presencia de lesiones premalignas cervicales y anomalías epiteliales detectadas en la citología anal, con un cociente de prevalencia de 1,77 (IC del 95%: 1,19-2,62) y un odds ratio de 2,69 (1,36-5,30). No se encontraron diferencias significativas en las variables de raza, tipo de relación sexual o tabaquismo. Conclusiones: nuestro estudio concluye que existe una asociación entre la neoplasia intraepitelial cervical relacionada con el VPH y la citología anal patológica.
Objective: the main objective of the study was to assess the prevalence of anal cytology in women with a history of cervical intraepithelial neoplasia. Method: cohort transversal study conducted from May, 2018 until August, 2020 at Pereira Rossell Hospital. Two cohorts were studied, one of which included women with a diagnosis of cervical intraepithelial neoplasia and the other one included healthy women who attended their routine follow up, in a 2:1 ratio. The total size of the sample was 205 patients, 135 of which were patients with cervical intraepithelial neoplasia (confidence interval being 95%), presuming a 10% prevalence of anal pre-neoplasic lesions. The sample size of the control cohort was 70 patients as per the pre-defined ratio. Results: a association was found between the presence of malignant lesions of the cervix and epithelial anomalies detected in the anal cytology, with a prevalence coefficient of 1.77 (CI: 95%: 1,19 - 2,62) and odds ratio of 2,69 (1,36 - 5,30). No significant differences were found between race, type of sexual relationships or smoking variables. Conclusions: our study concludes there is an association between cervical intraepithelial neoplasia related to HPV and pathological anal screening.
