RESUMEN

Background: Chronic rhinosinusitis (CRS) is an inflammatory condition classified into chronic rhinosinusitis with nasal polyps (CRSwNP) and chronic rhinosinusitis without nasal polyps (CRSsNP). Th cells manage inflammatory cells in CRS. Suppressor of Cytokine Signaling (SOCS) proteins regulate Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway in Th cells by polarizing toward Th1, Th2, and Th17 cells. This study evaluated the levels of SOCS1,3,5 in CRS patients to find associations with Th cells. Methods: In this cross-sectional study, 20 CRSwNP patients, 12 CRSsNP patients, and 12 controls participated. The infiltration of CD4+ T cells was determined using immunohistochemistry. The expression of specific transcription factors and SOCS proteins was assessed using real-time PCR. Cytokine levels were evaluated using ELISA. SOCS protein levels were investigated using western blot analysis. Results: The expression of SOCS3 increased in the CRSwNP group compared to CRSsNP and control groups (p <0.001). SOCS3 protein levels increased in the CRSwNP group compared to CRSsNP (p <0.05) and control (p <0.001) groups. Although there was a significant difference in SOCS5 expression between CRSsNP and control groups, SOCS5 protein levels were significantly different between CRSsNP and control (p <0.001) and CRSwNP (p <0.05) groups. Conclusions: Targeted therapies may be suggested for CRS by modulating SOCS3 and SOCS5 proteins that are responsible for polarization of Th cells toward Th2 or Th1 cells, respectively. JAK-STAT pathway targeting, which encompasses numerous cells, can be limited to SOCS proteins to more effectively orchestrate Th cell differentiation.

RESUMEN

INTRODUCTION: Hypopharyngeal squamous cell carcinoma (SCC) is rare, but highly aggressive. Due to the advanced stage of this cancer at the time of diagnosis, radical surgery with reconstruction of pharynx is the standard care with high morbidity and mortality rate. A safer partial pharyngectomy could also be used for invasive hypopharyngeal cancer. In this study, we investigated the short and long-term outcomes in patients with SCC of the pyriform sinus apex undergoing standard partial pharyngectomy using a new suturing technique, called end to side technique. METHODS: This case series was performed on 8 patients with SCC of the pyriform sinus apex at the otorhinolaryngology clinic. All participants underwent standard partial pharyngectomy using "end to side technique". Post-operative evaluations included 6 and 12 months CT scan and 1-year barium swallow. RESULTS: Of 8 patients, 7 were male (87.5%) and 1 was female (12.5%) with a mean age of 60 years old. All patients were diagnosed at stage III of hypopharyngeal cancer and cervical lymph node involvement was reported in 3 patients (37.5%). Tumor margins were negative in all patients. Fistula was reported in 2 patients (25%) which was managed using conservative treatments. CONCLUSIONS: According to our study, the standard partial pharyngectomy with end to side technique is a safe and feasible method for the surgical resection of the squamous cell carcinoma of the pyriform sinus apex with good short-term and long-term outcomes.

RESUMEN

OBJECTIVES: In recent years, conservation laryngeal surgeries, including partial pharyngectomy, have been introduced as an alternative procedure for selected cases of hypopharyngeal squamous cell carcinoma (HSCC). Reconstruction of these defects presents a considerable challenge for the surgeon after partial pharyngectomy due to its circumferential nature. In this case report, we represent the innovative "End to side" technique to reconstruct hypopharyngeal defect using the rolled supraclavicular flap after laryngeal-preserving partial pharyngectomy. METHODS AND RESULTS: A 70-year-old female presented with a history of progressive dysphagia and odynophagia. The evaluations revealed a T3N0M0 SCC of pyriform sinus. The mass was successfully resected through partial pharyngectomy, and the hypopharyngeal defect reconstruction was achieved using the rolled supraclavicular flap via the "End to side" technique. The patient was discharged after decannulation on day 10. The 3-week barium swallow was performed with no evidence of anastomotic leakage, and the oral feeding was started after NG tube removal. At week 5, complete movement of the true vocal cord on the one side and good phonation and deglutition was observed. There was no evidence of recurrence after 1 year. CONCLUSIONS: Laryngeal-preserving partial pharyngectomy and hypopharyngeal reconstruction with the rolled supraclavicular flap via the "End to side" technique could lead to good oncological and functional outcomes in selected cases of pyriform sinus.

RESUMEN

The number of children with congenital heart requiring anesthetic care is increasing. We describe the anesthetic management of a child with single ventricle candidate for laryngotracheal reconstruction. The patient suffered from severe subglottic stenosis due to prolonged intubation following Glenn shunt procedure. Anesthetic considerations in the care of patients with single ventricle for non-cardiac surgeries are reviewed. Particular concerns in the airway management of children with severe subglottic stenosis and during the tracheal surgery are also reviewed.

RESUMEN

INTRODUCTION: The introduction of laryngeal transoral procedures has created a shift in the treatment of laryngeal cancers towards the primary surgical management of patients. In this study, we aimed to evaluate the safety, efficacy, and feasibility of the transoral laser-assisted total laryngectomy (TLM-TL) in advanced laryngeal cancer. Case presentation. In this case report, we describe a case of a 50-year-old male patient presented to the otorhinolaryngology clinic with a history of hoarseness and odynophagia since 6 months. Based on the pathological and imaging findings, the diagnosis of stage IVa laryngeal squamous cell carcinoma with the involvement of the base, tongue, and left palatine tonsil was made for the patient, and transoral total laryngectomy with partial glossectomy via the TLM technique was planned. RESULT: The tumor was successfully resected by TLM-TL with clear surgical margins. No complication was observed after the surgery. Good functional recovery was obtained regarding swallowing and speech. The patient's oncologic and functional outcomes were evaluated for 2 years. Everything was satisfactory with good long-term cosmetic and laryngopharyngeal functional outcome and no sign of tumor recurrence. CONCLUSIONS: TLM-TL is a minimally invasive and cost-benefit endoscopic surgical procedure feasible in advanced laryngeal cancer with good long-term oncological and functional outcome. It could limit postoperative complications, mainly the incidence of pharyngocutaneous fistulae. It is also associated with better satisfaction after TL due to cosmetic benefits.

RESUMEN

INTRODUCTION: The endonasal mucosal or anatomic pathologies could lead to poor functional results and dissatisfaction after rhinoplasty. Although computed tomography (CT) scan has become an integral part of the diagnostic paradigm for patients with pathologies of the paranasal sinuses, the use of CT scan for preoperative evaluation of patients seeking rhinoplasty is up for debate. Our aim in this study was to compare the efficacy of CT scan in diagnosing nasal pathologies with other evaluating tools in patients undergoing rhinoplasty. DESIGN: In this randomized controlled trial study, 74 consecutive patients seeking cosmetic rhinoplasty referred to otorhinolaryngology clinic were randomly assigned into three groups based on the perioperative evaluation method: the CT group, the nasal endoscopy group, and the control group (anterior rhinoscopy only). Surgical planning was made according to perioperative findings, and the identified endonasal pathologies were corrected during the surgery. The functional and aesthetic outcomes of the rhinoplasty were assessed by Nasal Obstruction Symptom Evaluation (NOSE), Rhinoplasty Outcome Evaluation (ROE), and the Visual Analogue Scale (VAS) tools before surgery and at 12-month follow-up. RESULTS: All outcome measures improved significantly in either group toward one year after rhinoplasty (all with p value <0.05). Subjects in the CT group demonstrated greater improvement in the NOSE, VAS, and ROE compared to other two groups (NOSE: p value = 0.17; VAS: p value = 0.024; ROE: p value = 0.042). CONCLUSIONS: According to our study, perioperative CT is associated with greater patients' satisfaction and quality of life after rhinoplasty compared to either nasal endoscopy or anterior rhinoscopy. A preoperative CT scan may improve the outcomes of rhinoplasty.
