A male patient in his 70s who had undergone a regular upper gastrointestinal endoscopy noted a flat, erythematous area on the right soft palate of the oropharynx 9 months after his treatment of oropharyngeal cancer. Six months after noticing the lesion, endoscopy revealed that the lesion had rapidly developed into a thick, erythematous, bump. Endoscopic submucosal dissection was performed. Pathological analysis of the resected tissue found a squamous cell carcinoma with a thickness of 1400 μm invading the subepithelial layer. There are few reports on the growth speed of pharyngeal cancer and it remains unclear. In some cases, the growth of the pharyngeal cancer may be rapid, and it is important to follow up the patient in a short period of time.

American Journal of Otolaryngology 2024To investigate the clinical characteristics, diagnosis and prognosis of patients with laryngeal tuberculosis (LTB) combined with respiratory tuberculosis.
PURPOSE
To investigate the clinical characteristics, diagnosis and prognosis of patients with laryngeal tuberculosis (LTB) combined with respiratory tuberculosis.
MATERIALS AND METHODS
A retrospective analysis was conducted on 134 patients who underwent endoscopy and were eventually diagnosed with LTB. The patients' demographic characteristics, clinical manifestations, endoscopic features, auxiliary examination, imaging examination and prognostic characteristics were analyzed.
RESULTS
LTB patients had a median age of 45.5 years (range from 12 to 87 years) and a median course of 3.0 months (range from 0.1 to 72 months). The patients' symptoms mainly presented as hoarseness (97.0 %), abnormal sensation of pharyngeal (49.3 %), cough and sputum (41.0 %), pharyngalgia (39.6 %), dysphagia (10.4 %) and dyspnea (8.2 %). The positive rate of tuberculous symptoms was 25.4 %. Endoscopic features showed that the lesions mainly involved the glottis (87.3 %), presenting as unilateral lesions (66.7 %), near-full-length involvement (88.0 %), with mucosal waves significantly reduced (86.3 %), followed by supraglottis (43.3 %), subglottis (24.6 %) and the pharynx (15.7 %). The lesions may present as granulomatous proliferation (66.4 %), ulceration (65.7 %) or swelling and exudation (51.5 %). A total of 75 patients (56.0 %) were finally diagnosed with combined pulmonary tuberculosis (PTB), with a positive chest X-ray rate of 25.6 % and a positive chest CT rate of 71.2 %. A total of 42 patients who received anti-tuberculosis treatment were followed up, and 73.8 % of patients had significant improvement in symptoms. The morphology of the pharyngeal and laryngeal mucosa returned to basically normal (59.4 %) or scar-like (34.4 %).
CONCLUSIONS
LTB is usually found in middle-aged men, and patients' symptoms are mainly hoarseness, abnormal sensation of pharyngeal, pharyngalgia, cough and sputum, and can be combined with tuberculous symptoms. These lesions mainly involve multiple subregions, mainly in the glottis, and can be combined with pharyngeal involvement. There were various types of lesions. Half of the patients were complicated with PTB, and chest CT was superior to X-ray in the detection of pulmonary lesions. After regular anti-tuberculosis treatment, the symptoms and morphology of the pharyngeal and laryngeal mucosa of most patients were significantly improved.

Review
Herpes simplex virus (HSV) belongs to the family and is divided into two subtypes: HSV-1 and HSV-2. It is known that herpesviruses lie dormant in neural ganglion cells and are reactivated during times of stress, trauma, fever, and immunosuppression. While HSV primarily causes mucosal infections such as cold sores or upper respiratory tract manifestations, it can also lead to serious, life-threatening infections, particularly in immunocompromised patients. Although HSV is occasionally detected in airway samples from critically ill patients, true HSV pneumonia is rare. HSV pneumonia is thought to result from the aspiration of salivary secretions that can travel from the pharynx and tracheobronchial areas to the lungs. It can be difficult to diagnose, and the presence of HSV in respiratory specimens does not necessarily indicate true infection. Treatment with antiviral drugs such as acyclovir should be considered based on the clinical presentation, corroborative findings, and the presence of cytopathological changes in the bronchoalveolar specimen. The prognosis of HSV pneumonia is generally poor and early detection is critical for better outcomes. This review discusses the risk factors, clinical presentation, diagnosis, treatment, and prognosis of HSV pneumonia and emphasizes the importance of distinguishing between true infection and carrier status.

The roster of amdoparvoviruses (APVs) in small carnivores is growing rapidly, but in most cases, the consequences of infection are poorly understood. Red panda amdoparvovirus (RPAV) is highly prevalent in zoo-housed red pandas and has been detected in both healthy and sick animals. Clarifying the clinical impact of RPAV in this endangered species is critical, and zoological collections offer a unique opportunity to examine viral disease association in carefully managed populations. We evaluated the potential impact of RPAV in captive red pandas with a combination of prospective and retrospective analyses. First, we collected feces from 2 healthy animals from one collection over a 6-year period and detected virus in 72/75 total samples, suggesting that RPAV can be a long-term subclinical infection. We next investigated the infections using a retrospective study of infection status and tissue distribution in a cohort of necropsied animals. We performed polymerase chain reaction and in situ hybridization on 43 necropsy cases from 4 zoo collections (3 from the United States, 1 from Europe, 1997-2022). RPAV was present in these populations for at least 2 decades before its discovery and is detectable in common and significant lesions of zoo-housed red pandas, including myocarditis (3/3 cases), nephritis (9/10), and interstitial pneumonia (2/4). RPAV is also detectable in sporadic lesions, including multisystemic pyogranulomatous inflammation, oral/pharyngeal mucosal inflammation, and dermatitis. The colocalization of virus with lesions supports a role in causation, suggesting that despite the apparently persistent and subclinical carriage of most infections, RPAV may have a significant impact in zoo collections.

Ingested sharp foreign bodies rarely migrate extraluminally into adjacent organs such as the pharynx, lungs, and liver. Herein, we report a case of fish bone ingestion where the foreign body followed a unique migration trajectory. Computed tomography revealed a fish bone extraluminally located in the aortopulmonary space in the left mediastinum and peri-esophageal pneumomediastinum. Endoscopic examination indicated no injury to the esophageal mucosa but showed mucosal lacerations in the left hypopharynx. Accordingly, we reasoned that the fish bone penetrated the laryngopharynx and then descended in the mediastinum.

BACKGROUND AND AIMS
Superficial pharyngeal squamous cell carcinoma (PSCC) has received increasing attention as a therapeutic target in the GI field with recent innovations in endoscopic submucosal dissection (ESD). However, there are currently no defined criteria for the application of ESD to superficial PSCC. One of the problems encountered during follow-up after ESD is cervical lymph node metastasis (LNM). Identifying the clinicopathologic predictors of cervical LNM can help to provide a basis for the refinement of therapeutic strategies for superficial PSCC.
METHODS
The risk of cervical LNM was evaluated in 331 patients with superficial PSCC who underwent initial ESD between 2008 and 2021. Since tumor size, rather than depth, is the dominant factor in the current TNM classification for PSCC, the correlation between tumor size and thickness was investigated.
RESULTS
The median follow-up period was 4.8 years. The cumulative 5-year cervical LNM rate was 6.1%. Multivariate Cox proportional hazards regression analysis identified tumor thickness ≥1000 μm and lymphatic invasion as significant independent predictors. Among 204 cases with subepithelial invasion, both factors were also revealed to be significant independent predictors, suggesting that tumor thickness was superior to tumor size in predicting cervical LNM. Despite the positive correlation between tumor thickness and size, there was noticeable variability in the values (R = .20), and the current staging was inadequate to identify groups at high risk for cervical LNM.
CONCLUSIONS
Tumor thickness and lymphatic invasion are validated as significant independent predictors for cervical LNM and can be useful indicators to optimize the therapeutic strategies for superficial PSCC.

AIMS
Chemoradiotherapy is the standard treatment for advanced Oropharyngeal squamous cell carcinoma (OPSCC). Upcoming hypofractionation has led to better compliance and non-inferior results in various sites such as breast and prostate cancer etc. This study prospectively compared a dose-intensified schedule in advanced OPSCC with standard hypofractionation.
MATERIALS AND METHODS
Patients with advanced stage III and IV OPSCC suitable for radical chemoradiotherapy were eligible. Patients were alternatively allocated to both the treatment arms. Arm A planned to receive 64 Gy in 25 fractions (#) with concurrent cisplatin and Arm B received standard fractionation 70 Gy in 35 # with concurrent cisplatin. All patients completed a median follow up of 6 to 18 months. The primary end point was acute toxicity (less than 3 months) and late toxicity at 1 year. Secondary end point was disease free survival and overall survival at 1 year.
RESULTS
44 patients in arm A and 49 patients in arm B were recruited over 18 months. 34 patients completed full-dose radiotherapy in both arms. Maximum acute toxicity in arm A in terms of skin reaction was Grade II in 47.05% cases and mucositis grade II in 67.6% cases. In arm B grade II skin toxicity was seen in 47.1% and mucositis grade II was seen in 79.4 % cases. Ryle's tube dependency was seen in 38.2 % cases in arm A and 50% in arm B. Complete response rate at 3 months was equivalent in both arms in Arm A (100%), and in Arm B (96.7%). Disease free survival (DFS), Overall survival (OS) at 3 month, 6 months, and 12 months was comparable.
CONCLUSIONS
64 Gy in 25 fractions with concomitant chemotherapy is tolerable in patients with equivalent results and better compliance. Shorter fractionation schedule is more acceptable and we look forward for more randomized control trials.

UNLABELLED
Introduction: Oronasopharyngeal stricture is a rare sequel of oropharyngeal surgical procedure which can cause swallowing difficulty, dyspnea, sleep related breathing disorders, incompetence at the velopharynx due to soft palatal adherence. Case: Here we present a case of nine-year-old girl who presented to us with complains of nasal obstruction since 3 months and symptoms of sleep disordered breathing. She underwent adenotonsillectomy 5 years ago and coblator assisted palatoplasty and stricture release 4 months ago. On examination adenoid facies was noted, postpalatoplasty and tonsillectomy status with stricture between the anterior and posterior tonsillar pillars. Soft palate was stuck to posterior pharyngeal wall. Computed tomography scan was done which depicted homogenously enhancing soft tissue density causing complete nasopharyngeal airway obstruction. Oronasopharyngeal stricture release was performed under general anesthesia. Infant feeding tube was inserted through the nasal cavity and introduced through the oropharynx into exterior and was tied externally which was removed on postoperative day 5. Child is on regular follow up since 5 months and asymptomatic. Discussion: Oropharyngeal stricture is reported as a rare sequela of adenotonsillectomy. Many surgical techniques have been reported for release of similar oropharyngeal and nasopharyngeal stricture patterns such as triamcinolone injection, manual dilation method, plasma hook method, division and skin grafting, local flaps like pharyngeal or palatal mucosal flaps, and free flap techniques. Conclusion: Utmost care must be taken during the surgical procedure of oropharynx to prevent collateral damage to mucosal surfaces which can result in such devastating complications.

Review
Head and neck squamous cell carcinoma (HNSCC) develops from the mucosal epithelium of the oral cavity, pharynx, and larynx, and is the most common malignancy of the head and neck, the incidence of which continues to rise. The epidermal growth factor receptor is thought to play a key role in the pathogenesis of HNSCC. Inhibition of epidermal growth factor receptor has been identified as an effective target for the treatment of HNSCC. Many phytochemicals have emerged as potential new drugs for the treatment of HNSCC. A systematic search was conducted for research articles published in PubMed, and Medline on relevant aspects. This review provides an overview of the available literature and reports highlighting the in vitro effects of phytochemicals on epidermal growth factor in various HNSCC cell models and in vivo in animal models and emphasizes the importance of epidermal growth factor as a current therapeutic target for HNSCC. Based on our review, we conclude that phytochemicals targeting the epidermal growth factor receptor are potentially effective candidates for the development of new drugs for the treatment of HNSCC. It provides an idea for further development and application of herbal medicines for cancer treatment.
