The role of adjuvant systemic corticosteroid in pediatric retropharyngeal and parapharyngeal abscess.

OBJECTIVES: To evaluate the potential benefits of systemic corticosteroids as an adjuvant treatment for pediatric retropharyngeal abscess (RPA) and parapharyngeal abscess (PPA). METHODS: We retrospectively reviewed medical records of patients diagnosed with RPA and PPA who were admitted to Shenzhen Children's Hospital between January 2010 and January 2023. Data on demographic characteristics, clinical presentation, physical examination, laboratory data, use of corticosteroids, management, duration of hospital stay, need for surgical drainage, and complications were collected. Patients were divided into two groups: non-corticosteroid group (antibiotic only) and corticosteroid group (corticosteroid and antibiotic). RESULTS: A total of 111 patients were enrolled. There were 51 cases in non-corticosteroid group and 60 cases in corticosteroid group (10 cases received methylprednisolone and 50 cases received dexamethasone). There was no significant difference in sex, age, location of abscess, size of abscess and laboratory parameters at admission and discharge between the two groups. The surgical drainage rate was significantly lower in the corticosteroid group than in the non-corticosteroid group (p = 0.008). The hospital duration was also shorter in the corticosteroid group than in the non-corticosteroid group (p = 0.026). The hospitalization cost was significantly lower in the corticosteroid group than in the non-corticosteroid group (p = 0.000). CONCLUSION: The use of systemic corticosteroids along with antibiotics in children with RPA and PPA may reduce the need for surgical drainage, shorten hospital duration, and decrease hospitalization cost. Further studies are needed to confirm these findings and determine the optimal timing, duration, and route of administration of corticosteroids.

The Underestimated Role of Mast Cells in the Pathogenesis of Rhinopathies.

Mast cells (MCs) are involved in several biological processes, such as defense against pathogens, immunomodulation, tissue repair after injury, and angiogenesis. MCs have been shown to change from protective immune cells to potent pro-inflammatory cells, influencing the progression of many pathological conditions, including autoimmune diseases and cancers. The role of MCs in the pathogenesis of rhinopathies has often been underestimated, since previous studies have focused their attention on eosinophils and neutrophils, while MCs were considered involved exclusively in allergic rhinitis. However, recent nasal cytology findings have shown the involvement of MCs in several rhinopathies, such as NARMA, NARESMA, and CRSwNP. These recent evidences highlight the crucial role that MCs play in orchestrating the inflammation of the nasal mucosa, through complex biological mechanisms, not yet fully understood. In this context, a better understanding of these mechanisms is fundamental for practicing Precision Medicine, which requires careful population selection and stratification into subgroups based on the phenotype/endotype of the patients, in order to guarantee the patient a tailored therapy. Based on this background, further studies are needed to understand the pathophysiological mechanisms involving MCs and, consequently, to develop targeted therapies aimed to obtain a selective inhibition of tissue remodeling and preventing MC-mediated immune suppression.

[Features of the clinic, diagnosis and treatment of parapharyngeal abscesses in children: analysis of 121 observations]. / Osobennosti kliniki, diagnostiki i lecheniya parafaringeal'nykh abstsessov u detei: analiz 121 nablyudeniya.

Parapharyngeal and retropharyngeal abscesses (PPA) in children are a rare pathology, for the diagnosis of which it is necessary to use additional instrumental examination methods. The tactics of treating patients remains a subject of discussion. OBJECTIVE: To analyze the features of the clinic, diagnosis and treatment of PPA in children. MATERIAL AND METHODS: According to the hospital database, a retrospective analysis of the medical histories of children discharged from the clinic with a diagnosis of "J39.0 Retropharyngeal and parapharyngeal abscess" was carried out in the period from 01.01.14 to 31.12.19. In all cases, the diagnosis was confirmed by computed tomography (CT) data with contrast enhancement. Complaints at the time of treatment, anamnesis and instrumental diagnosis data, clinical features of the course of the disease and the effectiveness of treatment were analyzed. RESULTS: 121 children were treated for PPA (average age 73±41 months; Me=52.5 months), which is 0.4% of all hospitalized in the otorhinolaryngological department, 0.7% of the number of emergency hospitalizations, 0.8% of the number of hospitalized children with pharyngeal diseases, and 8.3% of the number of patients with pharyngeal abscess. Abscesses were more often localized in the upper pharynx, at the level of the I-II cervical vertebrae (49.6% of all observations); abscesses were found least often in the pharyngeal space (5.8%), there was no statistically significant difference between the right-sided and left-sided location: 47.9% and 46.2%, respectively. Surgical treatment was performed in 98 (81%) patients in the presence of an abscess capsule or an abscess diameter of more than 2 cm according to CT; the remaining 23 (19%) children were treated conservatively. The opening of the abscess was performed endopharyngeal, in the case of a pronounced deep lateral location of the abscess and its proximity to large blood vessels - with access through the tonsillar niche after preliminary tonsillectomy (19.4% of those operated). CONCLUSION: The final diagnosis of parapharyngeal and retropharyngeal abscess can be established by contrast-enhanced computed tomography. Conservative treatment is indicated for a limited group of patients at the initial stages of the disease, most patients need surgical treatment.

Oropharyngeal hemorrhage in patients with COVID-19: A multi-institutional case series.

BACKGROUND: Patients with COVID-19 who are intubated and require mechanical ventilation have been observed to have oropharyngeal bleeding necessitating otolaryngology intervention. METHODS: We report five cases of oropharyngeal hemorrhage in COVID-19 patients on mechanical ventilation requiring evaluation by otolaryngologists at George Washington University Hospital (GWUH) and Boston Medical Center (BMC) from March to April 2020. Institutional Review Board at both institutions exempted this study from informed consent because there were no identifiable patient characteristics, photographs, or imaging studies included. RESULTS: All five patients were managed conservatively; four required packing with Kerlix gauze by an otolaryngologist. Two patients had the additional requirement of extracorporeal membrane oxygenation (ECMO) and associated anticoagulation. Three patients improved with oropharyngeal packing; two had persistent bleeding. Three patients expired. Endotracheal tubes were repositioned less frequently due to the COVID-19 pandemic. CONCLUSIONS: Intubated patients with COVID-19 may have an increased risk of oropharyngeal hemorrhage. This may be due to anticoagulation, prolonged intubation, or decreased frequency of endotracheal tube repositioning. Otolaryngologists should wear appropriate PPE when managing this hemorrhagic complication.

HPV-Associated Oropharyngeal Cancer in the HIV/AIDS Patient.

Since their discovery as the etiologic agents of cervical cancer in the mid-1970s, human papillomaviruses (HPVs) have been linked with a growing number of epithelial-derived tumors, including head and neck squamous cell carcinomas. HPV demonstrates a particular predilection for causing tumors of the oropharynx, with the majority of cases involving infection with high-oncogenic risk HPV-16. People living with HIV are at increased risk of infection with HPV- and HPV-related oral complications even with adequate control of their HIV infection with antiretroviral therapy. In this chapter, we discuss the molecular mechanisms that underlie HPV-mediated oncogenesis in the oropharynx. We also describe the progress that has been made in understanding the epidemiology of oral HPV infection and the determinants of oral HPV-related pathology. Finally, we examine what can be done to treat and prevent oral HPV infection, benign lesions, and cancer, particularly in the context of the HIV-positive patient.

[Endoscopic negative pressure therapy of a post-laryngectomy pharyngocutaneous fistula-first report of a new therapeutic method. German version]. / Endoskopische Unterdrucktherapie einer pharyngokutanen Fistel nach Laryngektomie ­ Erstbeschreibung eines neuen Therapieverfahrens.

In the current first report, it is shown how a post-laryngectomy pharyngocutaneous fistula was successfully closed by endoscopic negative pressure therapy (ENPT; also termed endoscopic vacuum therapy, EVT). The duration of negative pressure treatment was 14 days. Up until now, ENPT has been used for treatment of transmural defects in the rectum and esophagus. The new endoscopic method can also be used in the ENT field for closure of pharyngocutaneous fistulas.

Globus pharyngeus: a review of etiology, diagnostics, and treatment.

Globus is a non-painful sensation of a lump or a foreign body in the throat, and it frequently improves with eating. Although globus is a common symptom, only little is known about the etiology, and the causes have remained controversial. Previously, globus was labelled as a hysterical symptom. However, nowadays, the research has been mainly focused on somatic causes and it is suspected that the etiology is complex. Because of the unclear etiology, the diagnostics and treatment are varying, predisposing patients to possible unnecessary investigations. This review presents the current literature of globus: its etiology, diagnostics, and treatment. In addition, a special aim is to discuss the rational investigation methods in globus diagnostics and present a diagnostic algorithm based on recent researches.

Management of Pharyngocutaneous Fistula With Negative-Pressure Wound Therapy.

BACKGROUND: Pharyngocutaneous fistula is a common complication of laryngopharyngeal surgery and is associated with increased morbidity and mortality. Beyond the classical management, negative-pressure wound therapy (NPWT) can be an alternative and effective treatment. CLINICAL REPORT: Two patients with pT3N0M0 squamous cell carcinoma of pyriform sinus were subjected to total laryngectomy and pharyngoesophageal reconstruction of a circular (patient 1) and an anterior wall defect (patient 2) with radial forearm free flap and pectoralis major muscle flap, respectively. Both developed a pharyngocutaneous fistula and NPWT was used.A significant decrease of the fistula aperture and exudate was observed after 22 and 21 days of NPWT in patients 1 and 2, respectively. After that standard wound care was instituted and closure of the fistulae was accomplished in 5 and 7 days, respectively. CONCLUSION: Negative-pressure wound therapy can be an effective treatment for pharyngocutaneous fistula closure, either in the setting of fistulae that persist besides multiple surgical revisions using muscle flaps or as a first-line therapy when fistulae develops.

Craniofacial Morphology in Midline Cervical Cleft: Case Report and Review of Literature.

Congenital midline cervical cleft is a rare anomaly of the neck. This paper presents the case of a boy diagnosed with this disorder in which a preliminary orthodontic treatment was implemented. The craniofacial anomalies associated with this malformation produced a defect that could only be successfully treated through the implementation of orthodontic and surgical treatments. In this case, congenital midline cervical cleft was accompanied by certain disorders within the facial structures of the skull, primarily mandibular retrusion, flattening of the contour of the mandibular base, and a steep angle between the cranial base and the mandibular plane.

[The mathematical approaches to differential diagnostics of acute pharyngeal diseases]. / Matematicheskie podkhody k differentsial'noi diagnostike ostrykh zabolevanii glotki.

The objective of the present study was to elaborate the program for differential diagnostics of acute pharyngeal diseases based on the 'ENT-Neuro' artificial neuronal network. The study group was formed by means of sampling patients with acute pharyngeal diseases from a set of case histories of the subjects presenting with acute inflammatory diseases. The data thus obtained were employed to develop the expert system to support the decision making process with the use of the 'ENT-Neuro' artificial neuronal network that allows to carry out diagnostics of various inflammatory diseases of the pharynx including the following nosological entities: paratonsillitis, parapharyngitis, acute tonsillitis, and acute pharyngitis, with the minimal probability of erroneous diagnosis (4%). The proposed expert system makes it possible to choose the optimal treatment strategy for the management of various pharyngeal diseases taking into consideration the severity of a concrete pathology and thereby to reduce to a minimum the risk of the related complications.

Hyperbaric oxygen therapy as an alternative to surgery for non-healing pharyngocutaneous fistula.

The aim of the study is to examine the utilization of hyperbaric oxygen treatment (HBOT) as an alternative to surgical treatment for non-healing postoperative phayngocutaneous fistula (POPCF). A retrospective study was conducted between 2012 and 2014 of referred patients who had failed conservative treatment for POPCF at other medical centers. Reevaluation at our department was followed by therapeutic management including daily HBOT. Eight male patients with a mean age of 62.3 years were included. The average period of conservative treatment was 1 month before admittance to our department. All patients were managed with HBOT and local debridement. Closure of the POPCF was proved by a barium swallow test in seven patients (87.5 %). HBOT is recommended for patients who have failed conservative treatment for POPCF post-laryngectomy, due to a high rate of successful (87.5 %) closure and should be considered as an alternative to surgical treatment.

Management of chronic laryngopharyngeal neuropathy in the United States and Europe.

OBJECTIVE: This study aimed to analyze differences in the evaluation of laryngopharyngeal neuropathy by laryngologists in the United States and Europe. METHODS: Members of the American Laryngological Association (ALA) and the European Laryngological Society (ELS) were surveyed. Questionnaires were emailed to all 179 members of the ALA and all 324 members of the ELS. RESULTS: Of the ALA members surveyed, 40 (23.3%) responded, compared to 72 members (22.2%) of the ELS group. Of the ALA respondents, 79.5% identified laryngology as their primary area of practice, whereas 56.9% of ELS respondents identified devoting more than 50% of their practice to laryngology. Of ELS laryngologists, 81.1% received training in laryngology or associated subspecialties. For diagnosing laryngopharyngeal neuropathy, the average comfort level on the Likert scale was significantly greater for ALA members than ELS members (P<.01). Furthermore, ALA laryngologists were less likely to consider laryngopharyngeal reflux as an overdiagnosed condition compared to ELS laryngologists (P<.05). CONCLUSION: Laryngologists in the United States and Europe vary significantly in their familiarity with laryngopharyngeal neuropathy. This could reflect either differences in awareness concerning this condition or a more critical perspective of European providers regarding the chronic laryngopharyngeal neuropathy (CLPN) diagnosis. As CLPN is still lacking definitive proof, the addition of European researchers could aid in validating CLPN and determining its overall effect on the chronic cough population.

Percutaneous radiologic gastrostomy via nasopharyngeal intubation for the treatment of patients with complete malignant pharyngoesophageal obstruction.

BACKGROUND/AIMS: For patients with complete malignant pharyngoesophageal obstruction (CMPO), percutaneous radiologic gastrostomy (PRG) under ultrasound/CT guidance can complicate it to cause failure due to unsatisfied stomach filling. In this study, we retrospectively investigated whether PRG via nasopharyngeal intubation is feasible and effective for these patients. METHODOLOGY: PRG via nasopharyngeal intubation was attempted in 21 patients with CMPO (mean 70.8 ± 8.23 years). The technique comprised a dilation of the stomach via nasopharyngeal intubation using a catheter, followed by fluoroscopically guided puncture and gastrostomy tube placement. Complications including hemorrhage, peritonitis, gastrojejunocolic fistula, infection of puncture site, tube blocking and outleakage was observed during and after the procedure. RESULTS: A 5F catheter was successfully inserted to the stomach under fluoroscopical guidance and subsequent PRG was performed in all 21 patients. Minor complications occurred in 14.3% patients including mild infection of the fistula in 1, tube blocking in 1 and unexpected tube drawing out in 1. Follow-up nutrition indexes revealed obvious improved nutrition compared to before PRG (P < 0.05). CONCLUSION: PRG via nasopharyngeal intubation was simple, feasible and effective for patients with CMPO.

Naso-oropharyngeal choristoma (hairy polyps): an overview and current update on presentation, management, origin and related controversies.

This review presents a comprehensive and updated overview of bigerminal choristomas (hairy polyps) of naso-oropharynx/oral cavity, and discusses the controversies related to nosology and origin from a clinico-embryologic perspective. English-language texts of the last 25 years (January 1989-January 2014) were collected from the PubMed/MEDLINE database using the given keywords. Of the 330 records, 64 full-text articles (mostly case reports/series) were selected, incorporating clinical data from 78 patients, after screening through duplicates and the given exclusion criteria. With the available evidence, hairy polyps appear more common than generally believed, and are increasingly being recognized as an important, often-missed cause of respiratory distress and feeding difficulty in neonates and infants. Such a child without any apparent cause should be examined with flexible nasopharyngoscope to specifically look for hairy polyps which might be life-threatening, especially when small. The female preponderance as believed today has been found to be an overestimation in this review. These lesions are characteristically composed of mature ectodermal and mesodermal tissue derivatives presenting as heterotopic masses, hence termed choristoma. However, little is known about their origin, and whether they are developmental malformations or primitive teratomas is debatable. Involvement of Eustachian tube and tonsils as predominant subsites and the speculated molecular embryogenesis link hairy polyps to the development of the first and second pharyngeal arches. They are exceptionally rare in adults, but form a distinct entity in this age-group and could be explained as delayed pluripotent cell morphogenesis or focal neoplastic malformations, keeping with the present-day understandings of the expanded "teratoma family".

Pharyngocutaneous fistulae after total laryngectomy: analysis of the risk factors and treatment approaches.

OBJECTIVES: To investigate the incidence and predisposing factors in the development of postoperative pharyngocutaneous fistula (PCF) after total laryngectomy. METHODOLOGY: A total of 166 patients with complete medical records who underwent total laryngectomy (TL) due to laryngeal cancer were analysed retrospectively. The mean age of the patients was 57.4 (+ 19.6) years. This study looked at a total of 32 different parameters considered to be effective in the development of pharyngocutaneous fistula after total laryngectomy. RESULTS: Thirty-two patients (19.2%) had a pharyngocutaneous fistula. Aged over 61 years (p = 0.003), Diabetes Mellitus (DM) (p = 0.002), alcohol use (p = 0.006), history of preoperative radiotherapy (p = 0.001), preoperative tracheotomy (p = 0.017), postoperative low levels of haemoglobin (Hb) (p = 0.029), low levels of preoperative albumin (p = 0.001), total protein and a low alb/glb (albumin/globulin) ratio (p = 0.001), serum prealbumin levels on the third and seventh postoperative days (p = 0.001), high postoperative CRP levels (p = 0.002), T4 stage (extralaryngeal) and presence of transglottic lesion (p = 0.003), presence of stage IV (p = 0.012) lesion, primary surgery accompanied by bilateral neck dissection (p = 0.047), T-shaped oesophagus suture, postoperative bleeding (p = 0.07), presence of postoperative fever (p = 0.001), presence of skin defect in the anterior neck (p = 0.001) and presence of postoperative depression (p = 0.001) were found to be statistically significant factors in the development of PCF. CONCLUSIONS: Our study found many parameters associated with an increased risk of the development of PCF. According to the multivariate regression analysis, aged over 61 years, DM, preoperative RT, preoperative tracheostomy, postoperative Hb under 10 g/dl, prealbumin under 17 mg/dl on the third postoperative day, and a postoperative fever of 38.3 degrees C and above were found be associated with a higher risk of the development of fistulae more than the other risk factors.

Acute tonsillitis and its complications: an overview.

Acute tonsillitis may be defined as inflammation of the tonsils, predominantly due to infection. It is part of the spectrum of pharyngitis, which ranges from localised tonsillar infection to generalised infection of the pharynx and commonly affects young healthy adults. Simple sore throats secondary to viral or bacterial pharyngitis are very common and generally do not require hospital admission or antimicrobial treatment. Supportive management in the form of analgesia and adequate hydration is often sufficient. However, there is potential for life-threatening complications to develop, highlighting the need for basic knowledge in the management of these conditions. This article aims to provide an overview of acute tonsillitis and its complications, including peritonsillar and parapharyngeal abscess formation. Specific attention will be given to the pathogenesis, diagnosis, investigation and management of each condition, in particular advising on emergency pre-shore treatment and indications for referral to an Ear, Nose and Throat Department. We will also summarise important guidelines and evidence from the literature to support these management decisions.

Prophylactic Percutaneous Endoscopic Gastrostomy (PEG) - The Importance of Nutritonal Support in Patients with Head and Neck Cancers (HNCs) or Neurogenic Dysphagia (ND).

BACKGROUND: We evaluated the effectiveness and safety of prophylactic PEG performed for the enteral nutrition support during the oncological treatment of patients with HNCs and as a part of the management of neurological patients experiencing neurogenic dysphagia. METHODS: In 2013 we followed up on a group of 23 HNC patients subjected to prophylactic PEG. We assessed the duration of the procedure, intraprocedural incidents and their causes, time to tube-refeeding and discharge after intervention, post interventional analgesia, early and late complications,toleration, costs and postoperative course of these patients after radical surgery maintaining PEG in place. In parallel we followed up on a group of 10 neurological patients who have undergone a PEG placement to improve the nutrional status and to prevent recurrent chest infections due to ND related silent aspiration. RESULTS: The procedures were performed under sedation with Midazolam and the mean duration was about 7 minutes.Postoperative analgesia was minimal. Refeeding through the tube was initiated 2-4h hours later and the patients were discharged 12-24h after the procedure. Early complications were not observed and later we noted 2 cases of peristomal infections, succesfully managed conservatively. After oncologic surgery we noted 2 (8.69%) pharyngocutaneous fistulas.Conservative care obliterated the fistulas at 6 weeks, maintaining the feeding tube in place. We also compared the results with a group of 27 patients fed through the naso-gastric tube and a group of 20 cases with open gastrotomy-tube prophylactically inserted. The 10 neurological patients had varied conditions but degenerative diseases like motor neuron disease (3 cases" 30%) and multiple sclerosis (2 cases -20%) took the lead we encountered one case of peristomal infection and one case of tube blockage resolved by replacement. We evaluated the nutritional status by controling the weight of these patients before and after PEG placement. A mean weight gain of 3.1 kg(range 1.2 â€" 7) was documented. CONCLUSIONS: PEG is a simple minimmaly invasive procedure performed safely under sedation. It takes a very short time and is virtually free of major complications. The requirements of analgesics are minimal. The refeeding is started early and the tube is well tolerated by the patient. PEG has an important role in the conservative healing of pharyngocutaneous fistula.PEG is the procedure of choice for the neurological patients.It prevents weight loss and aspiration pneumonia in patients with neurogenic dysphagia with a low rate of complications.

Parapharyngeal abscess is frequently associated with concomitant peritonsillar abscess.

To characterize patients with parapharyngeal abscess admitted to a Danish tertiary care centre and evaluate our management. This is a retrospective chart review. All records of patients with parapharyngeal abscess admitted to the Ear-Nose-Throat Department at Aarhus University Hospital, Denmark, from January 2001 through December 2011 were reviewed. In total, 63 patients (41 males), aged 4-89 years (median, 45 years) were included in the study. The mean annual incidence of parapharyngeal abscess was 0.9 cases/100,000 population. Thirty-three (52%) patients had concomitant peritonsillar abscess. In two patients the parapharyngeal abscess was accompanied by necrotizing fasciitis. The most frequent surgical approach used was intrapharyngeal incision in combination with tonsillectomy. The most commonly used antibiotic regimen was benzylpenicillin plus metronidazole. Seven (13%) patients returned to the operating theatre due to post-tonsillectomy haemorrhage or insufficient abscess drainage. Tonsillectomy and internal incision of the abscess in combination with a narrow-spectrum intravenous penicillin and metronidazole is a safe and efficient approach for managing parapharyngeal abscesses. This approach, however, carries a relatively high complication rate, requiring close surveillance in the early post-operative period. This is especially true for parapharyngeal abscess patients without peritonsillar abscess. In our series, these patients were more ill, more likely to experience complications, require intensive care, intubation, and tracheotomy, than parapharyngeal abscess patients with concurrent peritonsillar abscess. The frequent co-existence of parapharyngeal abscess and peritonsillar abscess favours careful consideration of addition of tonsillectomy to intrapharyngeal incision.
