The use of Preoperative Lidocaine to Prevent Stridor and Laryngospasm after Tonsillectomy and Adenoidectomy

The most important complications from tonsillectomy and adenoidectomy are bleeding, stridor, and laryngospasm. This controlled, double-blind study was designed to investigate the effects of topical and intravenous lidocaine on stridor and laryngospasm. A total of 134 patients scheduled for elective tonsillectomy and/or adenoidectomy were randomly separated into four groups. In the topical lidocaine group 4 mg/kg of 2% lidocaine was applied to subglottic, glottic, and supraglottic areas before endotracheal intubation. Normal saline solution was used topically for the first control group. In the intravenous lidocaine group, patients were given 1 mg/kg of 2% lidocaine before extubation, and the same amount of 0.9% NaCl was given to the second control group. Postoperative stridor, laryngospasm, cyanosis, bleeding, sedation degree, and respiratory depression were observed, and plasma lidocaine levels were measured. Both topical and intravenous lidocaine groups revealed less stridor and laryngospasm than the control groups, and no difference was found between the topical and intravenous lidocaine groups except the higher sedation scores in the early postoperative period for the intravenous lidocaine group.

Cricoarytenoiditis in rheumatoid arthritis: radiologic and clinical study.

The cricoarytenoid (CA) joint involvement in rheumatoid arthritis (RA) is not uncommon. In this study, clinical assessment, laryngeal endoscopy, and high-resolution computed tomography (HRCT) were used in 15 patients with RA to evaluate the diagnostic criteria of CA joint involvement. Symptoms owing to CA joint involvement were present in 66.6% of the patients. The frequency of involvement was 13.3% on laryngeal endoscopy but 80.0% with HRCT assessment. The most common HRCT findings were CA prominence (46.6%), density and volume changes (46.6%), and CA subluxation (39.9%). In some of the patients, soft tissue swelling (20%) near the CA joint and narrowing in the piriform sinus (33.3%) were also observed. Radiologic abnormalities related to CA joint involvement generally precede clinical symptomatology. Therefore, HRCT evaluation may be a useful method in the assessment of CA joint involvement in RA patients to exclude possible causes of laryngeal signs and symptoms.

Prevalence of Helicobacter pylori in Patients with Nasal Polyps: A Preliminary Report

Objectives: The aim of the study is to determine the presence of H. pylori in nasal polyps by both immunohistochemical staining with H. pylori antibody of biopsy specimens and enzyme‐linked immunoadsorbent assay (ELISA) of sera.

Superior thyroid artery arising from the common carotid artery.

A 63-year-old man was admitted with a 2-month history of dyspnea and hoarseness dating back 9 months. He had a 50-year history of smoking but denied excessive alcohol consumption. Physical examinat ion revealed a 4-cm transglottic, exophytic tumor involving both vocal cords. A 2-cm lump in the left jugular lymphatic chain was palpable. Endoscopy revealed a large mass originating from the epiglottis and obscuring the deep laryngeal structures. Biopsy findings confirmed that the tumor was squamous cell carcinoma. A total laryngectomy with left radical neck dissection was carried out that included peritracheal and retrosternal dissection. During the neck dissection the superior thyroid artery was noted to arise from the common carotid artery (Fig. 1).

Basement Membrane in Middle Ear Cholesteatoma Immunohistochemical and Ultrastructural Observations

We investigated the distribution of basement membrane zone (BMZ) components collagen type IV, collagen type VII, and fibronectin in human middle ear cholesteatoma, auditory meatal skin, and middle ear mucosa using both immunohistochemical and ultrastructural methods. Collagen type IV inununoreactivity of skin and middle ear mucosa is continuous in the BMZ, whereas cholesteatoma frequently showed absent immunoreactivity or focal discontinuities. Collagen type VII inununoreactivity is detected similarly within the BMZ of cholesteatoma and skin. Fibronectin immunoreactivity is observed within the dermoepithelial junction of skin and middle ear mucosa. In cholesteatoma, however, fibronectin immunoreactivity is markedly increased within the extrinsic BMZ and the subepithelial connective tissue. The ultrastructural arrangement of the BMZ of cholesteatoma is like that of skin; however, it exhibits distinct alterations of the lamina fibroreticularis and lamina densa. Our results outline cholesteatoma as a disease with disturbed cell matrix interactions analogous to those of wound reepithelialization.

Effect of chronic and short-term erythropoietin treatment on random flap survival in rats: an experimental study.

Objective The use of perioperative erythropoietin (EPO) therapy is gaining popularity to avoid blood transfusion and correct anemia in head and neck cancer surgery. The purpose of the study was to determine the effect of various doses and durations of EPO treatment on random flap survival.

Tularemia presenting as tonsillopharyngitis and cervical lymphadenitis: a case report and review of the literature

In this report, we describe a 57-year-old woman with oropharyngeal tularemia who presented with tonsillopharyngitis and cervical lymphadenitis. Clinical and radiological manifestations and histopathological characteristics of this disease are discussed with a review of the world literature. The oropharyngeal form of tularemia should be considered in the differential diagnosis of cases involving tonsillopharyngitis and cervical lymphadenitis, particularly in those not responding to penicillin treatment.

Cytokeratin expression pattern in congenital and acquired pediatric cholesteatoma

Pediatric cholesteatoma can be classified as congenital or acquired based on clinical criteria. We studied the expression patterns of five distinctive cytokeratins in both types of cholesteatoma in order to improve understanding of their pathogenesis and origin. A comparable expression pattern for CK10, CK14, CK18, CK19 and 34βE12 antigens was found in the matrix of congenital and acquired pediatric cholesteatoma. Our results demonstrate that congenital and acquired pediatric cholesteatoma exhibit an identical cytokeratin distribution pattern, suggesting that they share a common origin. Therefore, it seems possible that a portion of the so-called “acquired” cholesteatoma may actually originate from advanced congenital cholesteatoma with secondary destruction of the tympanic membrane in the pediatric patient population.

CT assessment of the effect of fluticasone propionate aqueous nasal spray treatment on lower turbinate hypertrophy due to vasomotor rhinitis

Conclusion. Fluticasone propionate (FP) aqueous nasal spray was objectively found to be effective and safe for the treatment of lower turbinate enlargement in patients with vasomotor rhinitis. Objective. To assess the efficacy of FP aqueous nasal spray treatment in lower turbinate hypertrophy due to vasomotor rhinitis using CT. Material and methods. Of 35 patients with hypertrophic lower turbinates due to vasomotor rhinitis, 20 were treated twice daily with FP aqueous nasal spray (200 µg/day) for 3 months continuously and 15 were treated with placebo vehicle as a control group. The local effect of the nasal spray was studied using CT and visual analog scales. Results. Treatment with FP provided significantly greater relief from the symptom of nasal obstruction compared with placebo over the entire 3-month treatment period (p < 0.001). When the change from baseline was compared between the two groups, FP produced statistically significant reductions in the mucosal area of the lower turbinates and in the thickness of the nasal mucosa after 3 months (p < 0.05).

Emotional effects of nasal packing measured by the Hospital Anxiety and Depression Scale in patients following nasal surgery.

The aim of this study was to test the validity of the Hospital Anxiety and Depression (HAD) Scale in patients who underwent nasal surgery as a method of screening for emotional disorders during their hospital stay. The study group consisted of 50 adult patients (29 male, 21 female) who underwent nasal surgery for different reasons, such as chronic sinusitis, nasal polyposis, and nasal septal deviation. Functional endoscopic sinus surgery and/or septoplasty were managed in these patients, and all of the patients had nasal packing applied bilaterally for 2 days. The HAD Scale was given to all of the patients 1 day before surgery and 1 day after surgery, with anterior nasal packing bilaterally during the hospital stay. The anxiety and depression levels of the male group were under the cutoff points. For the female group, the depression levels were under the cutoff points, and the anxiety levels were high in the preoperative period and decreased after the operation. Anxiety and depression levels in the pre- and postoperative periods for the male and female groups were analyzed by Paired t-test. No statistically significant result was found (p > .05). It was concluded that, for patients well informed about nasal packing and hospital conditions, nasal packing may be used safely, without any psychological disturbance. The HAD Scale should be a more useful screening method to diagnose emotional disorders, especially in patients who are hospitalized for a long time.
