- چکیده انگلیسی: Statement of the Problem: Sinonasal papilloma (SNP) is a rare benign lesion characterized by high recurrence rate and malignant transformation. Purpose: This study aimed to investigate the prevalence of human papilloma virus (HPV) infection in these lesions in South of Iran. Materials and Method: In this cross sectional retrospective study, a total of 41 patients, 38 SNP and 3 SNP/Squamous cell carcinoma cases, from 2007 to 2014 were studied. Human papilloma virus (HPV) DNA detection was performed by nested PCR method and positive cases were analyzed for high risk HPV-16 and HPV-18. Results: HPV was detected in 31.7%; HPV- 16 in 4.9% and HPV 18 was not detected at all. Dysplastic epithelium was detected in 53% that was not associated with HPV. Three cases were accompanied with malignant transformation that HPV genome was detected in only one case and none of them were positive for HPV16 /18 genomic DNA. Conclusion: Current research suggests that HPV may be involved in the development of SNP. But the high risk HPV is not important in malignant transformation. More studies are needed to elucidate the possible etiologic mechanism between HPV, inverted papilloma, and squamous cell carcinoma. Keywords ● Sinonasal ● Papilloma ● Carcinoma ● Human papilloma virus ● High risk

- چکیده انگلیسی: Statement of the Problem: Squamous cell carcinoma (SCC) is the most frequent oral cancer whose 5-year survival rate is 80% for early-detected lesions and nearly 30-50% for advanced lesions. Early detection of oral cancers and precancerous lesions can improve the patient’s survival and decrease the morbidity.Purpose: This study aimed to evaluate and compare the Ki-67 and MCM3 expression in cytologic smear of oral SCC (OSCC).Materials and Method: We examined 48 oral brush biopsies including 28 OSCC and 20 healthy non-smoking samples. Immunocytochemistry staining was performed for Ki-67 andMCM3 by using an EnVision-labeled peroxidase system, and labeling index (LI) was calculated.Results: Out of 28 OSCC cases, 27(96.4%) cases contained MCM3 positive cells and 22(78%) cases contained Ki-67 positive cells. All normal mucosa were Ki-67 and MCM3 negative. MCM3 and Ki-67 LI were significantly higher in OSCC than normal mucosa (p< 0.001). MCM3 LI was significantly higher than Ki-67 LI in OSCC group (p< 0.001).Conclusion: Immunocytologic evaluation of Ki-67 and MCM3 can be used for early detection of OSCC. Furthermore, MCM3 may be a more sensitive cytologic biomarker than Ki-67 in SCC patients. Keywords ● Squamous Cell Carcinoma ● Cytology ● Biopsy ● Ki-67 antigen ● Minichromosome Maintenance Complex Component 3

- چکیده انگلیسی: Statement of the Problem: Matrix metalloproteinases (MMPs) have been implicated in the pathogenesis of certain diseases and cancers via tissue destruction and can be secreted into the blood stream. MMP9 expression in the salivary gland tissue was evaluated but their serum level in the salivary gland tumors was not studied.Purpose: The aim of our study was to determine the concentration of serum MMP-9 in healthy participants and in patients with salivary gland tumor.Materials and Method: Using an ELISA kit, the circulating levels of MMP-9 in sera from 58 patients with salivary gland tumor (31 pleomorphic adenoma, 17 adenoid cystic carcinoma and 10 mucoepidermoid carcinoma) and 30 healthy controls was assessed.Results: The serum MMP9 level in patients with salivary gland tumors (380.0±301.3 pg/ml) also patients with benign tumors (354.3±218.7 pg/ml) (354.3±218.7 pg/ml) were significantly lower than that in the healthy group (727.4±624.6 pg/ml) (Respectively p= 0.02 and p= 0.01). Mean serum MMP9 concentration in malignant tumors was (402.3±441.8pg/ml) higher than benign tumors (354.3±218.7 pg/ml) but the difference was not significant (p= 0.9).Conclusion: Our results showed that serum level of MMP9 decreased in patients with salivary gland tumors which suggest that MMP9 may not have a potential role in development and pathogenesis of salivary gland tumor.

- چکیده انگلیسی: Background and objective: Oral tongue Squamous Cell carcinoma (SCC) commonly involves males between the sixth to eighth decades of life. Major risk factors are tobacco usage and alcohol consumption. The increasing number of patients developing oral tongue cancer without these well-known risk factors suggests that a viral infection, such as Human Papillomavirus (HPV), may be responsible for this increase, by acting as an oncogenic agent. This study investigated the prevalence of HPV infection and its clinicopathologic significance in oral tongue SCCs.
Material and methods: Tissue blocks from a total of 50 cases (patients with oral tongue SCC) and 50 controls (palatine tonsillar tissues with benign diagnosis) were selected. DNA was extracted from tumoral and non-tumoral tissue blocks. Detection of common HPV DNA by nested Polymerase Chain Reaction (PCR), and high-risk genotypes, HPV 16 and HPV 18, by conventional PCR, was achieved and the results correlated with clinicopathological parameters.
Results: Of the 50 patients (18 males and 32 females with a mean age of 57.36±12.18 years, and age range of 27 to 86 years), 7 (14%) had HPV positive results. None of the control group subjects had HPV DNA positive results (P-value of 0.012). The HPV genotype 16/18 was not detected in positive cases. No statistically significant association was found between HPV status and gender, age, tumor grade, tumor stage or lymph node involvement.
Conclusion: Although there was a significantly higher prevalence of HPV in oral tongue SCC, its association with carcinogenesis in this area requires further studies.- انتشار مقاله: 24-03-1395

- چکیده انگلیسی: Introduction:
Submandibular gland resection is a controversial issue in patients with oral tongue squamous cell carcinomas (SCC). This study aimed to determine the frequency of submandibular gland involvement in patients who had undergone elective submandibular gland resection following oral tongue SCC.
Materials and Methods:
This cross-sectional retrospective study was performed between 2001 and 2017 on patients with oral tongue SCC who had undergone glossectomy in a referral center for otorhinolaryngology surgery, Shiraz, Iran.
Results:
In this study, 131 patients were included. Their mean age was 59.84 years (range: 19-86). The mean tumor size was 2.83 cm (range 0.3-7). The vast majority (92%) of the patients were at stage III-IVa and had well (55%) to moderate (31%) differentiated tumor. The mean diameter of the submandibular gland was 3.87 cm (range: 1.5-6 cm). There was only one (0.76%) patient with submandibular involvement. She was an 80-year-old woman with a T2 well differentiated tumor without cervical lymph node involvement in the neck node dissection.
Conclusion:
In patients with oral tongue SCC, submandibular gland involvement is rare and its elective resection in not recommended.- انتشار مقاله: 16-08-1398

- چکیده انگلیسی: Introduction:
Cyfra 21 is a serum-soluble fragment of cytokeratin19. Increased Cyfra 21 serum levels and their benefit as a tumor marker have been shown in some malignancies. This study aimed to evaluate the serum levels of Cyfra 21 in patients with benign and malignant salivary gland tumors.
Materials and Methods:
In this cross-sectional study, the serum level of Cyfra 21 in 44 patients with malignant salivary gland tumors and 16 cases of pleomorphic adenoma were compared with 28 healthy controls using enzyme-linked immunosorbent assay (ELISA). Data were analyzed statistically using the Kruskal Wallis test, analysis of variance (ANOVA) and Spearman’s correlation tests.
Results:
Mean serum levels of Cyfra 21 were 0.135 ± 0.285 ng/ ml in the control group, 0.167 ± 0.142 ng/ ml in patients with pleomorphic adenoma and 1.059 ± 3.251 ng/ml in patients with malignant salivary gland tumors. There was no significant difference among groups. Cyfra 21 levels did not correlate with location of tumor, clinical stage or cigarette smoking.
Conclusion:
Results of the present study showed no significant difference in Cyfra 21 serum level in salivary gland tumors compared with normal individuals. In addition, Cyfra 21 serum level was not sufficiently sensitive to function as a tumor marker in salivary gland tumors.- انتشار مقاله: 12-10-1395

- چکیده:
- چکیده انگلیسی: Introduction:
Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetylation, causing ATP-dependent chromosome remodeling, and regulating transcription. MTA1 had been shown to be overexpressed in malignant tumors with the enhancement of invasion and metastasis.
Materials and Methods:
Fifty-six samples of salivary tumors from the Khalili Hospital archive, including 20 cases of pleomorphic adenoma, 17 cases of mucoepidermoid carcinoma, 19 cases of ACC, and 23 cases of normal salivary gland tissues were chosen for immunohistochemical analysis of MTA1.
Results:
MTA1 expression in the malignant tumors was significantly higher than that in pleomorphic adenoma (P<0.001), and higher in pleomorphic adenoma than the normal salivary glands
(P< 0.001). In total, 69.6% of normal salivary gland tissues showed MTA1, but all cases of salivary gland tumors were positive for MTA1. High nuclear expression of MTA1 was detected in 83.3% (30/36) of the malignant salivary gland tumors and 45% (9/20) of pleomorphic adenoma, while low MTA1 expression was seen in all of the normal salivary gland tissues. No statistically significant correlation was found between MTA1 protein expression and any clinicopathological features (P>0.05).
Conclusion:
Our findings demonstrate that MTA1 was significantly overexpressed in malignant salivary gland neoplasm in comparison to a lower level in benign pleomorphic adenoma, suggesting that MTA1 protein might be involved in carcinogenesis.- انتشار مقاله: 09-12-1393

- چکیده انگلیسی: Introduction: The presence of HER-2 has been shown to be a prognostic factor in many kinds of cancers, but its role in head and neck squamous cell carcinoma (HNSCC) is not still defined. The purpose of the current study is to investigate the role of HER-2 in HNSCC and its correlation with various clinicopathologic parameters. Materials and Methods: Peripheral blood samples were obtained from 17 healthy volunteers and 69 patients with HNSCC before curative surgery. The HER-2 level was determined in each sample by sandwich ELISA. Statistical analysis was performed using an independent t-test, one-way ANOVA, and Mann-Whitney Test. Results: Mean HER-2 serum levels in patients with HNSCC compared with healthy controls was not statistically significant (3.85ng/ml vs. 3.75ng/ml; P>0.05). The mean serum level of HER-2 was higher in patients with lymph node involvement, metastasis, invasion, tumor size ≥2 cm, and stage>1, although the differences were not statistically significant (P>0.05). Discussion: Mean HER-2 serum levels in patients with tumor size T3 and higher were greater than those from patients in stage T1 and T2, a finding which may be translated into disease progression, growth and invasiveness. Conclusion: In this study the mean HER-2 serum level in patients with HNSCC was found statistically insignificant compared with the healthy control group. The role of soluble HER-2 as a tumor marker is still controversial and needs further studies to clarify its clinical relevance for early detection or screening for HNSCC.

- چکیده:
- چکیده انگلیسی: Introduction:
Epistaxis is one of the most common medical emergencies, making the management of posterior epistaxis a challenging problem for the ear, nose, and throat (ENT) surgeon. In the cases of conservative management failure, ligation of the major arteries or percutaneous embolization of the maxillary artery is performed routinely in most units, but rates of failure and complications are high.The objective of this study was to assess the effectiveness of endoscopic sphenopalatine artery (SPA) cauterization in patients with refractory posterior epistaxis.
Materials and Methods:
Between April 2011 and January 2012, 27 patients (15 males and 12 females) with refractory posterior epistaxis underwent endoscopic SPA cauterization in two tertiary referral hospitals in Shiraz. Three patients underwent bilateral cauterization.
Results:
Four patients (from 30 arteries) had new epistaxis after surgery, three experienced subsequent epistaxis requiring medical treatment, and one patient had a minor epistaxis not needing treatment.
Conclusion:
The SPA electrocoagulation technique seems to be safe, simple, fast, and effective with low rates of morbidity and complications for the management of refractory posterior epistaxis. Endoscopic SPA cauterization should be considered as an immediate second-line management when conservative treatment as first-line management fails.- انتشار مقاله: 19-03-1391

- چکیده انگلیسی: Introduction:
The association between asthma and sinonasal disease has been established for years. As sinonasal disease is one of the factors that exacerbates asthma, effective treatment of this disorder may also improve and stabilize the asthmatic condition. This study examines the outcome of endoscopic sinus surgery (ESS) on asthmatic patients with massive nasal polyposis.
Materials and Methods:
Forty-five asthmatic patients were included in the study. All were operated on and analyzed in our department. A questionnaire (SNOT-20) investigating the subjective evaluation of asthma and sinonasal states was presented to the patients, while objective evaluations including nasal rhinoscopy, forced expiratory volume in 1 second (FEV1), and steroid use were conducted with 1–2 years of follow up.
Results:
Quality of life (QoL) improved in 97.8% of patients, while clinical symptoms, emotional signs, and social signs improved in 97.7%, 84.4%, and 93.3%, respectively. Medication use for asthma showed a similar improvement, with approximately 80% of patients reducing and 75.6% of patients discontinuing steroid use. A total of 91.1% of patients showed improvement in post-operative FEV1.
Conclusion:
ESS achieved a beneficial effect on sinonasal and asthma symptomatology in patients with nasal polyps and asthma. QoL was also improved in these patients.- انتشار مقاله: 20-10-1390
