RESUMO

PURPOSE: To identify the recurrence rate and risk factors for recurrence in patients with juvenile-onset recurrent respiratory papillomatosis (JORRP). METHODS: A retrospective review was performed for all JORRP patients who underwent surgery between 2002 and 2019 at our institution. The demographic characteristics and clinical parameters were recorded. Kaplan-Meier estimates and Cox proportional hazards models were used to analyze the rate of recurrence and its risk factors. RESULTS: Our study included 721 patients. The cumulative recurrence rates at 1, 5, and 10 postoperative years following initial surgery were 74.2%, 90.0%, and 94.3%, respectively. Age at diagnosis younger than 4.5 years (HR = 2.380, 95% CI [1.169-4.846], P = 0.017), high Derkay anatomical score (HR = 1.136, 95% CI [1.043-1.236], P = 0.003) and HPV type 11 infection (HR = 2.947, 95% CI [1.326-6.551], P = 0.008) were independent risk factors for recurrence. Adjuvant therapy with interferon was less likely to recur (HR = 0.237, 95% CI [0.091-0.616], P = 0.003). Additionally, gender, tracheotomy, mode of delivery, parity, expression of Ki-67, HPV vaccination, and surgical treatment method were not independently associated with recurrence (P > 0.05). CONCLUSION: Age at diagnosis younger than 4.5 years, high Derkay anatomical score and HPV type 11 infection were associated with an increased risk for recurrence in patients with JORRP. Adjuvant therapy with interferon may reduce the risk of recurrence.

RESUMO

PURPOSE: To this day, there is no cure for recurrent respiratory papillomatosis (RRP). Multiple surgical procedures are performed to achieve symptom relief and prevention of airway obstruction. A promising drug for RRP is the vascular endothelial growth factor (VEGF) binding antibody bevacizumab. This chemotherapeutic agent has an angiogenesis-inhibiting effect which inhibits tumor growth. The objective of this review was to investigate the efficacy of bevacizumab as treatment option for RRP, and to explore the difference of its effects between intralesional and systemic treatment. METHODS: A systematic search was conducted in Cochrane, PubMed, and Embase. Articles were included if bevacizumab treatment was given intralesionally and/or systemically. The methodological quality of the studies was assessed using the CAse REport (CARE) guidelines. RESULTS: Of 585 unique articles screened by title and abstract, 15 studies were included, yielding a total of 64 patients. In 95% of the patients treated with systemic bevacizumab, the post-bevacizumab surgical interval was considerably prolonged. More than half of them did not need any surgical intervention during mean follow-up of 21.6 months. Treatment with intralesional bevacizumab showed a lower efficacy: in 62% of the patients, the post-bevacizumab surgical interval (mean, 1.8 months follow-up) was extended when compared to the interval before the treatment. CONCLUSION: Systemically and intralesionally administered bevacizumab are effective treatment options for severe RRP. A systemic administration might be the treatment of first choice. Further prospective research with long term follow-up is advocated to elucidate this important topic.

RESUMO

OBJECTIVES: This study aimed to compare the prognosis according to age, genotype or human papillomavirus (HPV) variant in patients with recurrent respiratory papillomatosis (RRP). DESIGN: Non-concurrent cohort. PARTICIPANTS: Forty one patients with RRP. SETTING: Tertiary referral hospital. MAIN OUTCOME MEASURES: Disease severity was defined by the number of surgeries performed, and Derkay score at surgeries, obtained from medical records. HPV was detected and genotyped, and HPV-6 variants were also assessed. RESULTS: Fifteen (36.58%) individuals belonged to the juvenile RRP group (JoRRP, less than 18 years), while 26 patients (63.41%) were allocated at the adult group (AoRRP, equal or more than 18 years). JoRRP patients needed, in average, a higher number of surgeries to control the disease than AoRRP patients (mean difference: 3.36). Also, JoRRP patients showed a higher Derkay score at each surgery (mean difference: 3.76). There was no significant difference in the number of surgeries when we compared patients infected with HPV-6 or HPV-11, neither in accordance to HPV-6 variants. Patients with HPV-11 presented a higher mean Derkay score at surgery than those with HPV-6 (mean difference: 4.39); when co-variated by age, we observed that this difference occurred only among JoRRP patients (mean difference: 6.15). CONCLUSIONS: Age of onset of RRP has an important impact on number of surgeries to control disease. Patients with JoRRP and HPV-11 tend to present worse Derkay score at each surgery. HPV genotype among adults and HPV-6 variants had no impact on the outcome of the disease.

RESUMO

OBJECTIVE: To investigate the adult outcomes of children with juvenile-onset recurrent respiratory papillomatosis via long-term follow-up. STUDY DESIGN: Retrospective study. SETTING: Beijing Tongren Hospital. PARTICIPANTS: The study includes 121 patients with recurrent respiratory papillomatosis. MAIN OUTCOME AND MEASURE: We followed up respiratory papillomatosis patients aged least 14 years and analysed their clinical features based on recurrence-free time. RESULTS: In total, 112 (92.6%) patients underwent three or more operations. The age at initial operation was 4.3 ± 2.9 years; 47.9% (58/121) experienced recurrence and underwent surgical treatment after age 14. At follow-up, 5% (6/121) had died, 41.3% (50/121) had been recurrence-free for 5 years or more (cured group), and 53.7% (65/121) had recurrence in the past 5 years (recurrent group). The age at the last operation was 9.2 ± 4.6 years in the cured group. The overall operation frequency was higher in the recurrence group than in the cured group (17.8 ± 11.9 vs 8.7 ± 6.5). Additionally, the human papillomavirus (HPV) infection and tracheal dissemination rates were higher in the recurrence group than in the cured group (90.8% [59/65] vs 54.0% [27/50] and 26.2% [17/65] vs 10% [5/50], respectively). CONCLUSION: The mortality rate for juvenile-onset recurrent respiratory papillomatosis is 5%. Approximately 50% of children experience recurrence and require repeated operations in adulthood. No significant difference in sex, age at initial operation or adjuvant therapy between the cured and recurrent groups was observed; however, significant between-group differences were found in overall operation frequency, aggressive disease, tracheal dissemination of papilloma, and HPV infection.

RESUMO

BACKGROUND: Recurrent respiratory papillomatosis is a benign condition caused by human papillomavirus (HPV). Surgery is the mainstay of treatment, but numerous adjuvant therapies have been applied to improve surgical outcome. Recently, HPV vaccination has been introduced, but only smaller studies of its effect have been published. The present meta-analysis is intended as a possible substitute for a proposed but not yet realized multicenter randomized controlled trial. METHODS: A systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. PubMed, Embase, and Cochrane were systematically searched. All retrieved studies (n = 593) were reviewed and qualitatively assessed. In addition, 2 previously unpublished data sets were included. The systematic review included 11 studies, comprising 133 patients, of whom 63 patients from 5 studies were eligible for meta-analysis. A random-effects meta-analysis was conducted for the mean difference in number of surgical procedures per month before and after vaccination. RESULTS: The number of surgical procedures per month was significantly reduced after HPV vaccination compared with before vaccination (estimated mean, 0.06 vs 0.35). The mean intersurgical interval increased from 7.02 months (range, 0.30-45 months) before to 34.45 months (2.71-82 months) after HPV vaccination. CONCLUSION: The present study supports the continued use of the HPV vaccine as an adjuvant treatment for recurrent respiratory papillomatosis.

RESUMO

BACKGROUND: Viral respiratory infection (VRI) is a common contraindication to elective surgery. Asymptomatic shedding among pediatric surgery patients (PSPs) could potentially lead to progression of symptomatic diseases and cause outbreaks of respiratory diseases. The aim of this study is to investigate the incidence of infection among mild symptomatic PSP group and asymptomatic PSP group after surgical procedure. METHODS: We collected the induced sputum from enrolled 1629 children (under 18 years of age) with no respiratory symptom prior to pediatric surgery between March 2017 and February 2019. We tested 16 different respiratory virus infections in post-surgery mild symptomatic PSP group and asymptomatic PSP group using a quantitative real-time reverse transcriptase polymerase chain reaction (qRT-PCR) assay panel. We analyzed symptom data and quantitative viral load to investigate the association between viruses, symptoms and viral quantity in qRT-PCR-positive PSPs. RESULTS: Out of 1629 children enrolled, a total of 204 respiratory viruses were present in 171 (10.50%) PSPs including 47 patients with mild symptoms and 124 with no symptoms after surgery. Commonly detected viruses were human rhino/enterovirus (HRV/EV, 42.19%), parainfluenza virus 3 (PIV3, 24.48%), coronavirus (CoV NL63, OC43, HKU1, 11.46%), and respiratory syncytial virus (RSV, 9.9%). PIV3 infection with a higher viral load was frequently found in PSPs presenting with mild symptoms, progressing to pneumonia with radiographic evidence after surgery. HRV/EV were the most commonly detected pathogens in both asymptomatic and mild symptomatic PSPs. CoV (OC43, HKU1) infections with a higher viral load were mostly observed in asymptomatic PSPs progressing to alveolar or interstitial infiltration. CONCLUSIONS: Our study suggested that PIV3 is a new risk factor for VRI in PSPs. Employing a more comprehensive, sensitive and quantitative method should be considered for preoperative testing of respiratory viruses in order to guide optimal surgical timing.

RESUMO

OBJECTIVE: To evaluate the efficacy of MMR vaccine in the treatment of juvenile-onset recurrent respiratory papillomatosis as adjuvant therapy by experimental research. METHODS: Thirty-one children with RRP were enrolled and assigned randomly to intervention group or control group. Fifteen subjects in intervention group were treated with local application MMR vaccine on the lesion after surgery; sixteen subjects in the control group were treated with surgical excision alone. The quantity of virus of positive specimens was measured by fluorescence quantitative polymerase chain reaction. RESULTS: After treatment with MMR vaccine, viral load of intervention group was (9.56 ± 11.03) × 108  copies/ml, that of control group was (22.01 ± 17.78) × 108 copies/ml, and there was significant difference between the two groups (P = 0.040). CONCLUSIONS: Local application MMR vaccine as adjuvant therapy can reduce HPV viral load significantly. It is suggested that the MMR vaccine may inhibit replication of HPV DNA, but the curative effect needs further confirmation.

RESUMO

BACKGROUND: Recurrent respiratory papillomatosis (RRP) is a rare, chronic disease of viral etiology which is characterized by multiple, recurrent growth of papillomas in the aerodigestive tract. MATERIALS AND METHODS: The surgical outcomes and the recurrence rates of 106 patients with RRP of the larynx were analyzed. The patients were treated at the University of Magdeburg between 1983 and 2014. The surgical outcomes of conventional and laser surgery regarding time to relapse and complications were compared. In addition, the influence of the quadrivalent vaccine Gardasil® on the disease was analyzed in 10 patients. RESULTS: Children with RRP had a statistically significant greater number of surgeries throughout their lifetimes compared to adult patients. There were no differences between the adult (n = 79) and juvenile (n = 27) groups in the time to relapse and the number of surgeries/year. The time to relapse and number of procedures/year were not influenced by the various surgical methods. Complications after conventional and laser surgery were not statistically different between the two groups. Serious complications and the need for a tracheotomy were only reported after conventional surgery. In the 10 patients who were immunized with Gardasil®, a statistically significant lower number of surgeries/year after vaccination was achieved. CONCLUSION: RRP is a rare disease. Treatment requires experience and may be very difficult. The analysis of the course of the disease has shown that the treatment of choice is surgical excision with the CO2 laser combined with the quadrivalent or polyvalent vaccine. Consequent vaccination of both boys and girls has the potential to reduce the occurrence of RRP.

RESUMO

Juvenile onset current respiratory papillomatosis (JORRP), which is the commonest benign laryngeal disease in children, has not been well investigated. This study aimed at further evaluating the clinical features and surgery for such children with JORRP. Patients diagnosed as JORRP in our department from January 2011 to June 2014 were enrolled, and the demographic and clinical data were collected. All the patients were followed up after surgery, and the recurrences were recorded. A total of 124 patients were included and categorized into low recurrence (<4/year, n = 97) and high recurrence (≥4/year, n = 27) groups based on the recurrence at diagnosis, respectively. The demographic characteristics were comparable in two groups. There were more patients in high recurrence group who had dyspnea II-III, abnormal chest X-ray findings and severe illness, and needed electrocardiscope monitoring (P < 0.05). Patients who had dyspnea II (P = 0.008) and severe illness (P = 0.002) needed electrocardiscope monitoring (P = 0.014) in high recurrence group were more prone to have recurrence after surgery. Multivariate logistic regression analysis proved that high recurrence at diagnosis was an independent risk factor for recurrence after surgery in JORRP [95 %CI OR 17.342 (1.266, 237.608), P = 0.033]. The recurrence at diagnosis could be used as a prognostic factor for JORRP after surgery, which could help to improve the therapeutic efficacy in such children.

RESUMO

OBJECTIVES: To estimate the number of patients with recurrent respiratory papillomatosis currently managed in secondary and tertiary health care in the UK and the frequency of its treatment with radiofrequency cold ablation (Coblation™ ). DESIGN: Cross-sectional survey of ENT consultants in the UK with validation using Hospital Episode Statistics (HES) inpatient data. SETTING: Online survey. PARTICIPANTS: ENT consultants in the UK. MAIN OUTCOME MEASURES: Number of recurrent respiratory papillomatosis patients currently managed in acute care in the UK and frequency of use of Coblation. RESULTS: A total of 283 ENT consultants from 128 UK NHS healthcare trusts and health boards completed the online survey. Responses were received from 86% of surveyed organisations, and an estimated 45% of all ENT consultants in UK. The estimated number of recurrent respiratory papillomatosis patients from the cross-sectional survey was 918 (at August 2015) which included 730 patients in England. The number of recurrent respiratory papillomatosis patients in England estimated from Hospital Episode Statistics (2014/15 financial year) was up to 741. A total of 42 Coblation procedures conducted in the UK were identified from the cross-sectional survey; 36 were conducted in England compared with 34 identified from Hospital Episode Statistics. CONCLUSIONS: The numbers of recurrent respiratory papillomatosis patients and Coblation procedures identified in England from a cross-sectional survey and Hospital Episode Statistics were in broad agreement. Our study estimated 1.42 recurrent respiratory papillomatosis patients per 100 000 in the general UK population. We also estimated that Coblation procedures accounted for 3% of interventional treatments conducted in the UK recurrent respiratory papillomatosis population.

RESUMO

Respiratory adverse events, such as cough, hypoxia, laryngospasm, bronchospasm and stridor, are major causes of morbidity and mortality during pediatric anesthesia. Since several studies have shown that upper respiratory tract infection is an independent risk factor for perioperative respiratory adverse events, children presenting for elective surgery with upper respiratory tract infection require a careful evaluation to decide whether or not to proceed with anesthesia. However, there are no standard guidelines to proceed with or postpone anesthesia, and thus the decision pro- cess is often based on unique institutional, patient, surgical, and social factors. Most of perioperative respira- tory adverse events can be anticipated, recognized, and treated easily, while laryngospasm and bronchospasm that can lead to oxygen desaturation and death are serious complications and their prevention and treat- ment are challenging. Anesthesiologists should be fa- miliarized with the prevention and treatment of peri- operative respiratory adverse events.

RESUMO

Historically, diagnosis of enigmatic pulmonary disease after hematopoietic cell transplantation (HCT) required lung biopsy, but recent advancements in diagnosis and therapy for respiratory infections have changed how clinicians approach pulmonary abnormalities. We examined temporal trends in the use of lung biopsy after HCT. We retrospectively reviewed patients who underwent their first allogeneic HCT at the Fred Hutchinson Cancer Research Center between the years 1993 to 1997, 2003 to 2007, and 2013 to 2015 and subsequently underwent surgical lung biopsy for any reason. Lung biopsy between cohorts were analyzed using a Cox proportional hazards model with death and relapse considered competing risks. Of 1418 patients, 52 (3.7%) underwent 54 post-HCT surgical lung biopsies during 1993 to 1997 compared with 24 (2.1%) and 25 biopsies in the 2003 to 2007 cohort; 2 cases of surgical lung biopsies out of 786 HCT recipients occurred during the 2013 to 2015 cohort (.25%). The median time to biopsy post-HCT was 71.5 days (IQR, 31 to 89) for the early cohort and 97 days (IQR, 42 to 124) for the late cohort, for an overall biopsy incidence of .15 and .075 per 1000 patient days in the first year after HCT, respectively. Patients in the 2003 to 2007 cohort were less likely to undergo a lung biopsy (adjusted HR, .50; 95% CI, .29 to .83; P = .008) when compared with patients in the early cohort, but more patients in the early cohort underwent lung biopsy without antecedent bronchoscopy (25/54 [46%] versus 3/25 [12%], P = .005). Although infections were a more common finding at biopsy in the early cohort (35/1418 versus 8/1148, P < .001), the number of biopsies demonstrating noninfectious lesions was similar between the two cohorts (19/1418 versus 17/1148, P = .76). Fungal infections were the major infectious etiology in both cohorts (32/35 [91%] versus 5/8 [63%], P = .07), but there was a significant reduction in the number of Aspergillus species found at biopsy between the cohorts (30/54 versus 1/25, P < .001). A similar percentage underwent biopsy with therapeutic intent for invasive fungal disease in the 2 cohorts (8/54 [15%] versus 4/25 [16%]). Surgical evaluation of lung disease in HCT recipients significantly declined over a span of 2 decades. The decline from the years 1993 to 1997 compared with 2003 to 2007 was because of a reduction in the number of biopsies for post-transplant infections due to aspergillosis, which is temporally related to improved diagnostic testing by minimally invasive means and the increased use of empiric therapy with extended-spectrum azoles. This practice of primary nonsurgical diagnostic and treatment approaches to pulmonary disease post-HCT have continued, shown by low numbers of surgical biopsies over the last 3 years.

RESUMO

BACKGROUND: Flap transposition is an infrequent but far from exceptional thoracic surgical procedure. The aim of this retrospective study was to report our experience in a referral unit of general thoracic surgery analyzing the early results after flap transposition. METHODS: We retrospectively analyzed the clinical records, surgical notes, and postoperative results of a cohort of patients who underwent flap transposition in our unit from November 2000 to February 2013. RESULTS: Overall, a surgical approach adopting flap reconstruction techniques was performed in 81 patients (54 males, 27 females) with a median age of 62 years (range 20-87). Flap transposition was necessary to reconstruct chest wall after resection for malignancy (27 patients), to repair intrathoracic viscera perforation (15 patients), and to fill residual cavities secondary to pulmonary/pleural infection (39 patients). A pedicle muscle flap was transposed in most of cases (64 pts, 79 %), while in the remaining 17 cases (11 %), an omental flap was used. There were no immediate postoperative complications, while three in-hospital deaths occurred due to respiratory or multiorgan failure. Among patients undergone flap transposition to fill a residual cavity, we observed a recurrent bronchopleural fistula in three patients (7.7 %); such patients were treated by repeat flap transposition (2 cases) and by repeat cavernostomy (1 case). CONCLUSION: Flap transposition may be indicated as part of a multimodal treatment for severely ill patients requiring complex thoracic surgery.

RESUMO

Aim of this study was to explore influence of the quadrivalent HPV vaccine (Gardasil(®)) on the immune status of recurrent respiratory papillomatosis (RRP) patients. In retrospective observational study, six RRP patients who received the quadrivalent HPV vaccine and whose HPV seroreactivity was measured were included. Multiplex HPV Serology was used to determine HPV-specific antibodies pre- and post-vaccination. Surgical interventions and patient records were analyzed. Five HPV6 and 1 HPV11 infected patient were included. Mean antibody reactivity against the associated HPV type rose from 1125 median fluorescence intensity (MFI) pre-vaccination to 4690 MFI post-vaccination (p < 0.001). Median post-vaccination follow-up was 4 years. Poisson regression analysis showed that the quadrivalent HPV vaccine decreased the incidence rate of surgeries. The immune system of RRP patients is able to increase antibody reactivity against the associated HPV type. A double blind randomized controlled trial is needed to determine whether this immunological increase can cause decrease in number of surgeries.

RESUMO

In the last decades new endoscopic tools have been developed to improve the diagnostic work-up of vocal fold lesions in addition to normal laryngoscopy, i.e., contact endoscopy, autofluorescence, narrow band imaging and others. Better contrasted and high definition images offer more details of the epithelial and superficial vascular structure of the vocal folds. Following these developments, particular vascular patterns come into focus during laryngoscopy. The present work aims at a systematic pathogenic description of superficial vascular changes of the vocal folds. Additionally, new nomenclature on vascular lesions of the vocal folds will be presented to harmonize the different terms in the literature. Superficial vascular changes can be divided into longitudinal and perpendicular. Unlike longitudinal vascular lesions, e.g., ectasia, meander and change of direction, perpendicular vascular lesions are characterized by different types of vascular loops. They are primarily observed in recurrent respiratory papillomatosis, and in pre-cancerous and cancerous lesions of the vocal folds. These vascular characteristics play a significant role in the differential diagnosis. Among different parameters, e.g., epithelial changes, increase of volume, stiffness of the vocal fold, vascular lesions play an increasing role in the diagnosis of pre- and cancerous lesions.

RESUMO

A patient with a 20-year history of recurrent respiratory papillomatosis had progressive, bilateral tumor invasion of the lung parenchyma. We used conditional reprogramming to generate cell cultures from the patient's normal and tumorous lung tissue. Analysis revealed that the laryngeal tumor cells contained a wild-type 7.9-kb human papillomavirus virus type 11 (HPV-11) genome, whereas the pulmonary tumor cells contained a 10.4-kb genome. The increased size of the latter viral genome was due to duplication of the promoter and oncogene regions. Chemosensitivity testing identified vorinostat as a potential therapeutic agent. At 3 months after treatment initiation, tumor sizes had stabilized, with durable effects at 15 months.

RESUMO

Foreign body (FB) in the aerodigestive tracts has been commonly reported but findings of impacted foreign bodies in the nasopharynx following inhalation/ingestion are very rare. Most of the FB gets lodged as a result of forceful vomiting, coughing,and digital manoeuvres for removal of FB in the oropharynx. Several objects have been identified lodged in the nasopharynx. No age group is spared although most victims are children under 10 years of age. Foreign bodies in the nasopharynx can be uneventful or potentially dangerous depending on type, size and location as it may cause sudden airway obstruction, or local pressure necrosis of alimentary or respiratory tract or both. Presentation in children is usually with a history of swallowed FB which may not be witnessed in children, choking, cough, bluish discolouration, breathlessness, drooling of saliva, halitosis, rhinorrhoea, snoring, stridor, dysphagia, vomiting and dysphonia. A foreign body in the nasopharynx is a challenge to patient, parents, the physician and the ENT surgeon, as it may be miss-diagnosed, in the index case, as Pharyngotonsilitis. The index patient, a 14 month child,was presented with a two days history of fever, drooling of saliva, mouth breathing, and digital manipulation. Lateral imaging of the post nasal space following initial treatment with antibiotics, aided the diagnosis of a periwinkle shell in the nasopharyngx that was removed during a nasopharyngoscopy under general anaesthesia without complication and subsequently discharged home. This emphasizes a high index of suspicion for FB in the nasopharynx in children with history of missing foreign body, digital manipulation, drooling of saliva and mouth breathing. Lateral X-ray of the postnasal space, neck, chest and abdomen should be the minimum investigation required.
