Background: Sodium hyaluronate has been proposed as a treatment for improving the symptoms of chronic rhinosinusitis. The present study evaluated the effect of the intranasal administration of hyaluronic acid in a group of patients affected by chronic rhinosinusitis without nasal polyps (CRSsNP)., Materials and Methods: Thirty subjects aged 18-65 years affected by CRSsNP were enrolled. The subjects were randomly administered hyaluronic acid or isotonic saline solution by nasal nebulizer twice per day for 30 days. They were evaluated before (T0) and after the treatment (T1) with Sino-Nasal Outcome Test-22, visual analogue scale for rhinorrhea, nasal obstruction, facial pain and hyposmia/hypogeusia, nasal endoscopy, active anterior rhinomanometry, peak nasal inspiratory flow and nasal cytology., Results: Comparing the study and the control group, at T1 no significant differences were observed in both objective and subjective parameters. Being included in the study group rather than in the control group did not have a significant effect on the variation of the considered parameters between T0 and T1. Considering the effects of the micronized douches independently from the type of solution used (either hyaluronic acid or isotonic saline solution), although no difference emerged between study and control group for any of the objective parameters, there was an improvement of Sino-Nasal Outcome Test-22 scores (p = .0005), visual analogue scale for nasal obstruction (p = .0006) and for hyposmia/hypogeusia (p = .04)., Conclusions: The treatment with micronized nasal douches can improve the sino-nasal symptoms of CRSsNP, in particular nasal obstruction and olfactory ability. No advantage of the use of hyaluronic acid over isotonic saline solution emerged., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objectives: The aim of the present prospective, randomized, double-blind, and placebo-controlled investigation (approved by the Ethical Committee of Padova University Hospital [Italy]) was to assess the effect of a nasal gel containing a combination of silver sucrose octasulfate and potassium sucrose octasulfate (Silsos gel® [SG]) in wound healing after endoscopic sinus surgery (ESS) for chronic rhinosinusitis in terms of: nasal symptoms (SNOT22), endoscopic appearance of the sinonasal mucosa (Lund-Kennedy score), nasal air flow (anterior active rhinomanometry), evidence of mucosal inflammatory processes (nasal cytology and histology), and microbiological growth., Methods: Thirty-four patients with chronic rhinosinusitis were randomized on a 1:1 ratio to receive after ESS either SG or placebo (contained only the excipients [carbopol and propylene glycol] in the same concentrations as in SG)., Results/conclusions: Judging from the present prospective investigation on patients who underwent ESS for chronic rhinosinusitis, treatment with SG seems to enable a significantly faster improvement in specific symptoms (assessed on the validated SNOT22 scale) than placebo. Patients treated with SG also had a quicker improvement in the endoscopic appearance of their nasal mucosa after ESS than patients treated with placebo. These endoscopic improvements in the SG group were also confirmed at the long-term follow-up, while the same did not apply to the placebo-treated group., (Copyright © 2015 Elsevier Inc.

Objectives: Before the widespread use of antibiotics, most deep neck infections (DNIs) stemmed from complicated pharyngeal infections. Nowadays, they seem to be due mainly to dental infections. In 2010, our group reported that DNIs originated from a major salivary gland in 14% of cases. The main endpoint of the present investigation was to review our experience of the diagnosis and treatment of DNIs of salivary gland origin. We also compared the characteristics of DNIs originating from salivary glands with those originating elsewhere., Methods: Between 2000 and 2011, 44 patients were treated for DNIs of salivary origin at our institution. These patients were compared with 191 cases of DNI diagnosed as having other sites of origin., Results/conclusions: In the present series, DNIs originating from a major salivary gland accounted for 19% of all cases of DNI of known origin. Patients with DNI of salivary gland origin were more likely to be elderly than those whose DNI originated from elsewhere (p=0.000). Our multivariate statistical model showed that comorbidities (p=0.051, statistical trend) and the need for surgical treatment (p=0.028) independently predicted long-term hospitalization for DNIs originating from a major salivary gland., (Copyright © 2015 Elsevier Inc.

Background: Adenosquamous carcinoma (ASC) of the head and neck is a rare malignancy characterized by loco-regional and distant aggressiveness. At histology, ASC reveals two distinct, juxtaposed components, squamous cell carcinoma (SCC), and true adenocarcinoma., Methods: The immunohistochemical expression of AE3, CK19 and CAM5.2, and HPV infection was tested in a case of laryngeal ASC., Results: The patient had no regional lymph node metastases, but developed a recurrence in neck soft tissues shortly after primary radical surgery. The laryngeal surgical specimen had the typical morphological features of ASC. The tumor's squamous and glandular components were both strongly and diffusely immunoreactive for AE3 and CK19, whereas CAM5.2 selectively stained only the gland-like part. We found no high- or low-risk HPV DNA (28 genotypes) in the specimens. The patient underwent salvage extended radical neck dissection and received postoperative radio-chemotherapy. At 4-month follow-up control, neck recurrence was found. Palliative chemotherapy was instituted., Conclusions: An accurate histological and immunohistochemical diagnosis is mandatory to differentiate ASC from conventional SCC. Radical surgical excision is recommended for laryngeal ASC. Adjuvant postoperative therapy is administered in most cases, but there are no widely accepted indications for these treatments., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Purpose: Reported outcomes of postoperative radiotherapy (PORT) for laryngeal squamous cell carcinoma (LSCC) have varied and sometimes been disappointing. The aim of the present preliminary study was to investigate whether a given immunohistochemical pattern of Maspin expression in laryngeal carcinoma cells could be prognostically associated with response to PORT., Materials and Methods: Thirty-two consecutive patients treated for LSCC with primary surgery and PORT. The subcellular (nuclear vs non-nuclear) pattern of Maspin expression was assessed immunohistochemically on LSCC surgical specimens and analyzed in relation to recurrence rate (RR) and disease-free survival (DFS)., Results: A non-nuclear Maspin expression was found in 23 of 32 cases (72%), and all recurrences (17 cases) occurred in this subgroup of patients. A non-nuclear Maspin expression was strongly associated with recurrence [p = 0.0002, hazard ratio (HR) 5.58] and a shorter DFS (p = 0.0004) after PORT for LSCC. Even in N0 patients, a non-nuclear Maspin expression was associated with a significantly higher RR (p = 0.04, HR 1.42) and a shorter DFS (p = 0.02). Among the common clinic-pathological parameters considered, only N stage showed a trend toward an association with prognosis in terms of DFS (p = 0.08)., Conclusion: Assessing subcellular patterns of Maspin expression in LSCC specimens could identify patients less likely to respond to PORT, who might benefit from combined chemo-radiotherapy to improve the efficacy of adjuvant protocols., (Copyright © 2015 Elsevier Inc.

Purpose: Smoking is a self-destructive behavior that is known to induce remodeling of the lower airways, leading to squamous metaplasia, but little is known about its effects on the nose and paranasal sinuses. Nasal irrigations are often mentioned as measures for treating sinonasal inflammations. The purpose of our study was to compare the effects of nasal irrigations with sulfurous-arsenical-ferruginous thermal water or isotonic sodium chloride solution in smokers with nonallergic chronic rhinosinusitis, based on clinical and olfactory evidence., Materials and Methods: The present study was a prospective, randomized, double-blind study performed in a tertiary academic referral center. Seventy smokers with nonallergic chronic rhinitis were enrolled. Nasal endoscopy, rhinomanometry, nasal cytology, and odor threshold measurements were performed in subjects randomized to daily nasal irrigations with either thermal water or isotonic sodium chloride solution for 1 month., Results: Immediately after the treatment, the thermal water irrigations revealed a positive pharmacologic action, judging from a tendency toward lower nasal resistances (P = .07) and larger numbers of ciliated cells in the patients treated (P = .003). Endoscopic findings in the thermal water group were still better than in the control group a further 2 months later (P = .03)., Conclusions: Our results indicate that nasal irrigations with thermal water had a good effect on endoscopic objective signs, nasal resistances, and epithelial trophism., (Copyright © 2012 Elsevier Inc.

Objectives: Nasal irrigations are mentioned among the adjunctive measures for treating several sinonasal conditions. Hyperchromatic supranuclear stria (HSS) in the ciliated cells (CCs) has recently been suggested as a potential cytological marker of the anatomofunctional integrity of nasal mucosa. The aim of this study was to compare the effects of nasal irrigations with sulfurous, salty, bromic, iodic (SSBI) thermal water or isotonic sodium chloride solution (ISCS) in patients with nonallergic chronic rhinosinusitis, considering the endoscopic, functional, microbiological, and cytological evidence (including the ratio of HSS-positive CCs to total CCs [the HSS+ rate])., Methods: In a prospective, randomized, double-blind setting, 80 patients were recruited for nasal irrigations with SSBI water or ISCS for 1 month., Results: An endoscopically assessed significant clinical improvement was seen after both SSBI thermal water and ISCS irrigations. Before treatment, Staphylococcus aureus was isolated in 5 patients in the SSBI thermal water group and 4 in the ISCS group. After the nasal irrigations, there was no sign of the bacteria in either group. Only the SSBI water irrigations significantly reduced total nasal resistance, as determined by rhinomanometry. Mild nasal irritation (6 cases) and episodes of extremely limited epistaxis (5 cases) were only reported after SSBI thermal water irrigations. Neither type of nasal irrigation significantly increased the mean HSS+ rate at cytological control after 1 month., Conclusions: Both types of nasal irrigation improved the endoscopic and microbiological features of patients with nonallergic chronic rhinosinusitis, whereas only SSBI irrigations significantly reduced total nasal resistance. Further investigations are needed based on longer treatments and follow-up periods to establish whether the HSS+ rate is useful for monitoring clinical improvements in chronic rhinosinusitis treated with nasal irrigations., (Copyright © 2011.

Acinetobacter baumannii strains are isolated in up to 1% of nosocomial infections mostly from intensive care units immunocompromised patients and are associated with high mortality rates. A baumannii infections include pneumonia, urinary tract infection, endocarditis, skin and soft-tissue infections, surgical-site infection, meningitis, osteomyelitis, and septicemia. We report an extremely rare case of deep neck abscess due to multidrug-resistant A baumannii infection. The isolate strain was analyzed by a repetitive sequence-based polymerase chain reaction typing method: the isolate profile was compared with other strains obtained from isolates recovered in the hospital in that period. Our patient underwent 2 neck explorations and antibiotic treatment (tigecycline 50 mg, twice per day). Five weeks after admission, the patient was discharged in good general conditions. Considering the other obtained strains, 4 different profiles were identified, one as prominent (profile A, 18 isolates), the index case (B), and 2 others (C, D) as divergent., (Copyright 2010 Elsevier Inc.

Purpose: Cell death by apoptosis is considered a regulator of cell number; cancer cells are defective in their response to apoptosis. Many potential markers of apoptosis are under study: M30 immunoreactivity is confined to the cytoplasm of apoptotic epithelial cells and is expressed during early apoptosis. Mammary serine protease inhibitor (MASPIN), a suppressor of tumor growth, seems to be involved in the induction of tumour cell apoptosis. The aim of our preliminary study was to investigate, for the first time, the relations between MASPIN subcellular pattern of expression, nuclear MASPIN expression, M30 expression, and prognosis in laryngeal carcinoma., Materials and Methods: Subcellular pattern of distribution of MASPIN and nuclear MASPIN expression were immunohistochemically determined in 66 consecutive cases of laryngeal carcinoma. M30 expression in correspondent carcinoma fields was also calculated., Results: M30 expression was significantly higher in the group of laryngeal carcinomas with MASPIN nuclear localization (P = .024). Our investigation found a reduced carcinoma recurrence rate in the group of patients with MASPIN nuclear localization (P value = .0086). The log-rank test showed a significantly longer disease-free interval in patients with nuclear MASPIN localization (P = .029)., Conclusions: These preliminary results support the hypothesis of an apoptosis-sensitizing effect of nuclear MASPIN in laryngeal carcinoma with the potential perspective of a clinical use of the tumour suppressive proapoptotic function of MASPIN.

Purpose: Parotid fistula is a well-known complication of parotidectomy or penetrating injury of the parotid gland. The management of parotid fistula has been controversial, and numerous conservative and surgical treatment methods have been described., Methods: We report 3 cases of parotid fistula after partial parotidectomy, which were treated by botulinum toxin injection under electromyographic control into the residual substance of parotid gland., Results: Complete healing of the fistula was achieved with a single botulinum toxin treatment in all patients. No side effects were observed after the treatment. The patients are disease-free after 21, 18, and 14 months, respectively., Conclusions: In the considered cases, the localized injection of botulinum toxin into the parotid gland resulted to an effective and long-lasting treatment of postparotidectomy fistula.

Purpose: Supracricoid laryngectomy (SCL) permits local control and 5-year survival rates similar to total laryngectomy in selected cases of advanced-stage laryngeal carcinoma. Although most of the reports regarding the surgical technique and oncological results have been proposed by European groups, increased interest in SCL has also been shown in recent years by American surgeons. There is still a lack of comprehensive studies about functional outcomes (respiration, deglutition, phonation) after SCL. Materials and methods This report briefly evaluates the functional outcomes of SCL recorded by the Department of Otolaryngology Head and Neck Surgery of Padua University since 1998 and critically reviews recent English-language literature describing SCL functional results., Results: The present review confirms that the available data on functional results were collected using heterogeneous methods, parameters, and evaluation scales., Conclusions: Every effort has to be made to uniform the format for presenting outcome data, particularly on swallowing and voice parameters. Defining guidelines to evaluate the functional results of SCL may facilitate interstudy comparability.
