Otitis media with effusion (OME) is one of the most common causes of hearing loss (HL) in children. It has been reported that several factors such as eustachian tube dysfunction, insufficiencies in the aeration of the mastoid cells, allergies, immunity, and infections play an important role in the etiology of the disease. Little is known about the role of Helicobacter pylori (H. pylori) in extragastric diseases. Because of the near location of the nose, sinuses, tonsils, and adenoids to the eustachian tube and middle ear, we believe it is possible to have H. pylori in the middle ear. The present study was designed to investigate the presence of H. pylori by polymerase chain reaction (PCR) in the middle ear effusion of patients with OME. The study was performed on 21 patients, 19 patients were affected bilaterally, and 2 patients were affected unilaterally, from which 40 specimens were collected. OME was diagnosed through findings by otoscopic examination and tympanogram. The middle ear fluid samples were collected under sterile conditions. A total of 40 samples was stored at -80°C until analyzed by PCR assay. From 40 specimens, 2 specimens were serosal and 38 specimens were mucoid. PCR results of the study in assays for Helicobacter pylori were not positive in all collected specimens. Overall, probably there was no H. pylori organism in free-floating form and thus could not be detected by PCR.

Background: Otitis media with effusion is one of the leading causes of hearing loss in children. Effective treatment of effusion in the middle ear requires appropriate empirical treatment and characterization of responsible pathogens. Objective of the present study was to detect pathogens in clinical samples from patients with otitis media with effusion in our area and to determine the sensitivity profile of isolated organisms to commonly used antibiotics. Methods: Sixty three samples of middle ear effusion were aseptically obtained from 36 children, who had been treated up to at least two weeks before sampling. They were analyzed using standard bacteriological and multiplex polymerase chain reaction (PCR) assays. Antibiotic susceptibility tests were also performed. Results: PCR analysis showed that DNA of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were present in 60 (95.2%) of the samples. The culture-positive effusion for Streptococcus Pneumoniae, HaemophilusInfluenzae and Moraxella catarrhalis was 34.9%. Almost all isolates of Streptococcus pneumoniaee were sensitive to ciprofloxacin and erythromycin, and none of them was sensitive to co-trimoxazole. None of H. Influenzae isolates was sensitive to erythromycin, cefixim, co-trimoxazole, ampicillin and amoxicillin. None of M. Catarrhalis isolates was sensitive to ceftriaxone, co-trimoxazole, ampicillin and amoxicillin. Conclusion: Compared with other studies using PCR method, the number of H. influenza isolates was in higher in the present study (95.2%). Antibiotic sensitivity profiles of pathogens isolated in this study were different from others. Thus, we can determine empirical antibiotic therapy based on sensi-tivity profile in our geographic area.

Introduction: The use of cartilage as a grafting material has been advocated in cases where there is a high risk of graft failure, such as subtotal perforations, adhesive processes, and residual defects after primary tympanoplasties. The purpose of this study was to compare the graft acceptance rates and auditory outcomes of cartilage tympanoplasty operations using a palisade technique with those of primary tympanoplasty using temporalis fascia in a homogenous group of patients. Study Design: Prospective study. Materials and Methods:The study population included 54 patients who were operated on in two groups (palisade technique & temporalis fascia technique) with each group containing 27 patients. Patients with pure subtotal perforations (perforation of >50% of the whole tympanic membrane [TM] area), an intact ossicular chain, at least a one month dry period, and normal middle ear mucosa were included in the study. Grafts acceptance rates and pre- and post-operative audiograms were compared. The follow-up time was six months. Results: Graft acceptance was achieved in all patients (100%) in the palisade cartilage tympanoplasty group and in 25 patients (92.5%) in the temporalis fascia group. This difference was not statistically significant (P= 0.15). Comparison of the increases in mean speech reception threshold, air–bone gap, and pure-tone average scores between both techniques showed no significant changes. Conclusion: Our experience with the palisade cartilage technique demonstrates that subtotal or total perforation at high risk for graft failure can be treated efficiently, and that a durable and resistant reconstruction of the TM with reasonable auditory function can be achieved.

Background Actinomycosis of the tonsils has been reported in a variable percentage of tonsil specimens by other authors. This study determines the incidence of actinomyces in the palatine tonsil and evaluates the clinical diagnoses and histopathological features of tonsillectomy specimens. Methods In a retrospective study, 204 patients who had undergone tonsillectomy for recurrent tonsillitis (group A) and for sleep apnea without a history of recurrent tonsillitis (group B) were enrolled. Results The prevalence rate was significantly higher in the adult compared with the pediatric population. The prevalence of tonsillar actinomycetes colonization was higher in patients who had undergone tonsillectomy for recurrent tonsillitis (43.9%) than in patients who had undergone tonsillectomy for obstructive sleep apnea (26.3%). The prevalence did not differ by sex of patient. Histopathological analysis of resected tonsils did not show active tissue infection. There was a statistically significant relationship between the presence of actinomycosis and age, with a greater occurrence of actinomycosis in adult patients. Conclusion Although actinomyces colonization is more prevalent in patients with recurrent tonsillitis than sleepdisordered breathing, but the presence of actinomyces does not indicate any active disease.

Background: The main cause of Alzheimer's disease (AD) is loss of cholinergic function. So, the choice strategy of therapy is to increase the level of acetylcholine (Ach) in the brain of by acetylcholinesterase inhibitors (AchEIs) such as Donepezil. This study evaluated the effect of donepezil on cerebral blood flow using non-invasive transcranial doppler (TCD) sonography. Methods: This clinical trial was performed on AD patients in two groups of case and control, each consisting of 11 patients. The case group who received donepezil medication was examined by TCD before (baseline), after four weeks of oral treatment with 5 mg/d donepezil and a further four weeks of 10 mg/d donepezil, administered orally. The control group did not receive any medications effective on AD and were examined by TCD only once. Peak systolic velocity (PSV), end-diastolic velocity (EDV) and mean flow velocity (MFV) velocities of posterior cerebral artery (PCA) and middle cerebral artery (MCA) were assessed and mini-mental state examination (MMSE) was carried out. Findings: There were not any significant difference between the case and control groups, in terms of age and sex. In the case group, mean MMSE score reached 20.2 ± 2.8 from a baseline value of 15.8 ± 3.3 after four weeks of oral treatment with 5 mg/d donepezil, and reached 20.6 ± 3.9 after four more weeks at 10 mg/d donepezil (P < 0.0001). In MCA, the difference in PSV and MFV values after four weeks of treatment at 10 mg/d donepezil was statistically significant, compared with the baseline values (P = 0.002 and 0.025, respectively). In PCA, the values of MFV and EDV after four weeks of treatment with 10 mg/d donepezil were statistically significant in comparison with the baseline value (P = 0.015 and 0.014, respectively). Conclusion: Donepezil, especially administered in doses of 10 mg/d, has an effect on increasing cerebral blood flow velocity and MMSE score in AD, but more extensive trials by other researchers are recommended.

- Abstract
Objective: We aimed to compare the graft success rate and hearing outcomes in patients with large tympanic membrane (TM) perforation in underlay and over-underlay approaches., Methods: This is a prospective double-blind randomized controlled clinical trial with a parallel design. Patients aged 15-75 years old with large TM perforation (more than 50% of TM) who operated at Khalili hospital affiliated with Shiraz University of Medical Science, Iran, were enrolled. Exclusion criteria were recent otorrhea, revision surgery, and pathologic intraoperative findings such as the presence of cholesteatoma, cholesterol granuloma, ear canal polyp, or damaged ossicle. In the first group, the underlay method and in the second group over-underlay method were performed. Graft success rate, atelectasis, and audiology outcomes were evaluated after 6 months., Results: The investigation was conducted on 84 patients in the underlay and 67 patients in the over-underlay group. Although there was a higher rate of graft failure (9%) in the over-underlay group in comparison with the underlay group (4.8%), the difference was not statistically significant ( p -value = .34). No atelectasis was seen in both group. Although, between-groups comparison of the preoperative and postoperative speech reception thresholds (SRT) and air-bone gaps (ABG) values showed statistically significantly lower SRT and ABG in the over-underlay technique, the difference was clinically negligible., Conclusion: Both techniques provide the same graft success rate, but SRT and ABG were significantly lower in the over-underlay technique after the operation., Levels of Evidence: 1b., Competing Interests: The authors declare that they have no conflict of interest., (© 2023 The Authors.

- Abstract
Background: Fungal rhinosinusitis (FRS) encompasses a various spectrum of diseases. Histopathology is the "reference method" for diagnosing FRS, but it cannot determine the genus and species. Moreover, in more than 50% of the histopathologically proven cases, the culture elicited no reliable results. This study was an attempt to evaluate the diagnostic efficiency of semi-nested polymerase chain reaction (PCR) from formalin-fixed paraffin-embedded (FFPE) functional endoscopic sinus surgery (FESS) in FRS patients., Methods: One hundred ten specimens were subjected to DNA extraction and histopathology examination. The amplification of the β-globin gene by conventional PCR was used to confirm the quality of extracted DNA. The semi-nested PCR was performed using ITS1, ITS2, and ITS4 primers during two steps. Sequencing the internal transcribed spacer region (ITS1-5.8S-ITS2) to identify causative agents was performed on PCR products., Results: Sixty-four out of 110 samples were positive by histopathology evidence, of which 56 samples (87.5%) were positive by PCR. Out of 46 negative samples by histopathological methods, five samples (10.9%) yielded positive results by PCR. Sensitivity, specificity, positive predictive value, and negative predictive value of the semi-nested PCR method were reported 87.5%, 89.2%, 92.7%, and 85.2%, respectively. The kappa factor between PCR and histopathological methods was 0.76, indicating substantial agreements between these two tests., Conclusion: Due to the acceptable sensitivity and specificity of the present method, it might be used to diagnose fungal sinusitis infections along with microscopic techniques. This method is recommended to confirm the diagnose of suspected fungal sinusitis with negative histopathology results., (© 2022 The Authors.

- Abstract
Objective: Post-tonsillectomy pain is a common morbidity in children. The aim of this study was to compare the efficacy of celecoxib with acetaminophen on pain relief in pediatric day-case tonsillectomy., Methods: We compared the analgesic effect of celecoxib (99 patients) with acetaminophen (100 patients) for the management of post-tonsillectomy pain. Post-tonsillectomy pain score was evaluated three times a day for 7 days. In addition, the incidence of post-tonsillectomy bleeding and the rate of patients who returned to regular diet were evaluated., Results: In the first day, we observed lower mean pain score in the celecoxib group, than the acetaminophen group ( P = 0.013). The overall pain score in other days was not significantly different between the two groups. In the celecoxib group, more patients resumed regular amount of oral intake within the first 3 days. Also, the rate of post-tonsillectomy bleeding in the two groups was not statistically different., Conclusion: We recommend celecoxib as a more suitable choice than acetaminophen for post-tonsillectomy pain management in the first day and resuming regular diet within 3 days.Level of Evidence: 1b., Competing Interests: The authors declare no potential conflict of interest., (© 2021 The Authors.

- Abstract
Objectives: The aim of this study was to evaluate whether intraoperative ciprofloxacin-soaked gelfoam is safe in tympanoplasty or not., Method: In this randomized, double-blind controlled clinical study, we included 100 patients between 18 and 60 years old, having perforation ≥50% of the tympanic membrane and dry ear for at least 2 months who were a candidate for underlay tympanoplasty via postauricular approach. We used ciprofloxacin soaked gelfoam in the case group and betamethasone soaked gelfoam in the control group for packing the middle ear cavity and external auditory canal during their operation. The graft success rate and tympanogram after 6 months follow-up period was considered as the primary outcome. Also, we evaluated the postoperative hearing results 6 months after the surgery as the secondary outcomes., Results: Postoperative microscopic otoscopy showed a graft success rate of 100% (44/44) and 97.7% (42/43) in the case and control groups, respectively. The level of improvement between the two groups was not significant for air-bone gap (ciprofloxacin: 9.01 ± 7.89 dB, betamethasone 5.31 ± 10.53 dB, P = .160), and speech reception thresholds (SRT; ciprofloxacin: 10.23 ± 8.62 dB, betamethasone 7.33 ± 12.60 dB, P = .260). 93.2% of all the ears in the case group and 81.4% of those in the control group achieved postoperative air-bone gap within 20 dB, but the difference between them was not significant ( P = .118)., Conclusions: We found that the application of ciprofloxacin impregnated gelfoam in the middle ear, and the external auditory canal had no adverse effect on the graft success rate in tympanoplasty., Levels of Evidence: 1b., Competing Interests: The authors declare no conflicts of interest., (© 2021 The Authors.

- Abstract
Purpose: Pain and hemorrhage are common morbidities after tonsillectomy. Although many studies have focused on post-tonsillectomy pain, inadequate researches are available on wound healing. Hence, there is a definite need for a novel technique to facilitate the healing process and thereby improving the post-tonsillectomy recovery., Methods: This prospective and randomized study was conducted on 60 adult patients who underwent tonsillectomy. They were divided into two groups of control and amniotic membrane (AM). Human amniotic membrane was applied over the tonsillar bed as a biologic dressing. Post-tonsillectomy pain and bleeding were evaluated. Also, the healing rate was assessed on days 5, 10 and 15 post-operatively., Results: The pain score in the AM group was lower than that in the control group during the first week after surgery (P < 0.0001). Moreover, the AM group returned faster to their normal diet in comparison with the control group (P < 0.0001). With respect to the healing rate, there were no significant differences between the groups on day 5 (P > 0.05), whereas a significant difference was seen on days 10 and 15 post-surgery (P < 0.0001). There was no significant difference between the two groups in terms of post-operative bleeding (P ≅ 1)., Conclusion: We observed that the use of AM graft as a biologic dressing might be beneficial in reducing post-operative pain and promoting the wound healing process. The results represent a further step toward developing a new technique for coverage of tonsillar fossa with sheeting or wearing grafts.

- Abstract
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.

- Abstract
Introduction: Otolaryngology is a field with a high referral rate; however, there is a dearth of research on the quality of referral letters written in this field. This study was carried out to explicitly assess the quality of referral letters, more specifically in the field of otology., Materials and Methods: Two otologists assessed referral letters written by general practitioners or primary care physicians working as family physicians. They were asked to make independent assessment on different variables related to the quality of referral letters and their appropriateness. A "qualified referral letter" in the current study is defined as a letter with standard items, including, description of chief complaint, description of associated symptoms, relevant physical findings, past medical history, drug history, family history, and reasons for referral., Results: A total of 1000 referral letters written by 652 primary care physicians were investigated in the current study. The obtained results indicated that 74% of referral letters to otologists contained inadequate information regarding various items in the referral letters. Symptoms, diagnosis, and signs were only reported in 28.3%, 28.9%, and 3.6% of the letters, respectively. The findings showed that most common reasons for referrals were uncertainty in diagnosis (52.4%), persistence of the patient (32.6%), and failed therapy (32%). With regards to case-specific conditions, the highest referral rates were related to external otitis, otitis media with effusion, and acute otitis media., Conclusion: According to the obtained results of the current study, the content of referral letters were insufficient or inappropriate. Therefore, it is recommended to improve otolaryngology syllabus and provide suitable courses for undergraduate students in order to become familiar with the importance of referral letter writing.

- Abstract
Introduction: Tympanoplasty is a standard surgical procedure for the treatment of chronic otitis media. In this study, we aimed to determine the effect of the predictive factors of middle ear risk index (MERI) in patients undergoing tympanoplasty., Materials and Methods: A total of 200 patients who underwent tympanoplasty surgery from 2008 to 2018 at Khalili hospital in Shiraz were evaluated. In this study, variables such as age, sex, systemic diseases (diabetes mellitus, hypertension), location and size of tympanic membrane perforation (TMP), health of the opposite ear, dryness duration of the ear, presence or absence of myringosclerosis during surgery, type of operation and the risk of MERI were evaluated., Results: The success rate for a 6-month follow-up of patients was 88%. Results showed that there was a significant difference between the MERI scores and the three types of operation of intact canal wall (ICW), canal wall down (CWD) and non mastoidectomy (P < 0.001). The longer the dryness duration of the ear, the MERI score was lower. When MERI score is low, the patient doesn't need mastoidectomy. Also, the worse the opposite ear, the higher the MERI score was. The highest MERI score was in patients undergoing CWD, and the lowest MERI score was in patients undergoing simple tympanoplasty., Conclusion: MERI score is a useful tool for predicting the success rate of tympanoplasty and helps the surgeon planning the type of tympanoplasty.

- Abstract
Objective: Prevention of granulation tissue formation and acceleration of epithelialization of the mastoid cavity in canal wall down (CWD) mastoidectomy by use of amniotic membrane (AM) as a biologic dressing., Study Design: Prospective and randomized study., Methods: During CWD mastoidectomy, an inferiorly base musculoperiosteal flap was rotated into the cavity. In order to coverage of this flap, the AM (75 ears) or the temporalis fascia (control group, 73 ears) was used. The times for mastoid cavity epithelialization were compared in both groups., Results: In the AM group, duration of complete epithelialization of the cavity was 41.4 ± 7.7 days, whereas in the control group it was 59.2 ± 9.1 days. Duration of time for complete epithelialization in the AM group was shorter than in the control group, which was significant (P < 0.0001)., Conclusion: The use of AM in CWD mastoidectomy is beneficial in minimizing postoperative epithelialization time., Level of Evidence: 1b Laryngoscope, 129:1453-1457, 2019., (© 2019 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Introduction: There are a few studies that compare the outcomes between primary and revision tympanoplasties. The purpose of the present study was to compare the results of type I tympanoplasty (i.e., synonymous to myringoplasty) and revision myringoplasty based on the closure of tympanic membrane perforation and hearing improvement., Materials and Methods: This prospective single-blind study was carried out on a total of 240 patients with tympanic membrane perforation at a tertiary referral center. The subjects underwent primary or revision myringoplasty. Grafting success rate and hearing results were measured and the comparison between the primary and revision groups was drawn., Results: Grafting success rate was reported as 96.6% (112 out of 116 cases) for myringoplasty, while in revision myringoplasty the success rate of 78.2% (97 out of 124 patients) was achieved (P=0.001). Speech reception threshold was 23.1±9.2 dB and 24.9±13.1 dB in the primary and revision groups, respectively (P>0.05). However, the percentage of air-bone gap on audiometry≤20 dB were 83.8% and 76% in the primary and revision groups, respectively (P=0.26)., Conclusion: The findings of the present study have shown that although grafting success was reported significantly better in myringoplasty (tympanoplasty type 1), compared to that in revision myringoplasty, it did not reveal any superiority over revision tympanoplasty regarding the hearing outcomes. No consensus was achieved due to a great number of controversies in the literature.

- Abstract
Introduction: Adenotonsillar hypertrophy (ATH) may present with growth retardation. Insulin-like growth factor 1 (IGF-1) mediates the anabolic effects of growth hormone (GH) on tissues. Most of the circulating IGF-1 molecules are bound to insulin-like growth factor-binding protein 3 (IGFBP-3). IGF-1 and IGFBP-3 serum levels reflect the levels of daily mean serum GH and are used as indices for evaluating the serum level of GH. This study aimed to determine the effect of adenotonsillectomy on IGF-1 and IGFBP-3 serum levels in patients with ATH or recurrent tonsillitis. Furthermore, we aimed to investigate the effect of adenotonsillectomy on growth indices such as weight and height., Materials and Methods: A total of 100 randomly selected children with a diagnosis of ATH or recurrent tonsillitis with a mean age of 10.2 ± 1.4 years (range, 3-17 years) were enrolled in the intervention group. Of those, 53 were boys and 47 were girls. The control group included 100 healthy children (62 boys and 38 girls) with a mean age of 8.5 ± 1.5 years (range, 4-15 years). Growth indices such as weight and height were measured and documented at the time of surgery and 6 months after the operation. Blood samples were taken preoperatively and repeated 6 months after adenotonsillectomy. The coated-tube immunoradiometric (IRMA) method was used to measure IGF-1 and IGFBP-3 levels., Results: Postoperative IGF-1 and IGFBP-3 serum levels as well as weight and height showed were significantly greater in comparison with preoperative measurements in both the intervention and control groups (P<0.001). At the end of study, the intervention group showed significantly greater changes from baseline in IGF-1 and IGFBP-3 serum levels, weight, and height in comparison with the control group (P< 0.001)., Conclusions: This study shows that adenotonsillectomy in children with ATH or recurrent tonsillitis increases IGF-1 and IGFBP-3 serum levels in comparison with preoperative levels by affecting the GH-IGF-1 axis, and subsequently leads to a faster increase in growth indices compared with healthy peers during the same period.

- Abstract
Some studies have shown that post-tympanostomy tube otorrhea (PTTO) is a common complication after tympanostomy tube insertion. There are wide range of controversies about the incidence of PTTO and different methods of preventive treatment. The aim of this study was to determine the incidence of early PTTO in persistent otitis media with effusion in our centers. We also investigated the effect of preventive treatments on the incidence of early PTTO in children with persistent otitis media with effusion. This multi-central study comprised 536 ears belonging to children with otitis media and effusion for at least 3 months, referred for complications arising from post-tympanostomy tube insertion. The patients were randomly divided into three treatment and control groups. In the first group of patients, the middle ear cavity was irrigated with isotonic saline after myringotomy. The second group received oral amoxicillin three times a day for 7 days postoperatively. The third group had similar treatment as the second group, in addition to topical ciprofloxacin drop, 4 drops three times a day for 3 days after operation. The control group did not undergo any treatment. Early post-tympanostomy tube otorrhea was detected in 6 ears (1.1 %), including 3 (2.2 %) from the control group and 3 (2.3 %) from the first group. There was no statistically significant difference in early PTTO between integrated treatment groups and control group (P = 0.111). As the total rate of early post-tympanostomy tube otorrhea was very low, there was no significant difference between the 3 treatment groups and control group. Our study did not support the routine use of preventive therapy. A period of at least 3 months watchful waiting before tympanostomy tube insertion may help reduce the incidence of PTTO.

- Abstract
Today, cochlear implantation has become the standard procedure for rehabilitation of people with impaired sensory neural hearing. This procedure can be done through different techniques. The present study aimed to compare the standard technique (ST) with creation of "C" incision into the scalp with suture fixation and limited-incision technique (LIT) with creation of subperiosteal pocket without any fixation. The outcomes included operative time and complications. This retrospective study was conducted on 343 consecutive cochlear implantations. The patients received cochlear implants at our institution between 2004 and 2011. The complications were identified as "minor" or "major". All the complications and operation times were assessed for the two surgical techniques. The overall rates of complications were 4.4 % (11 out of 252) and 2.2 % (2 out of 91) for ST and LIT, respectively. The results revealed no significant difference between the two fixation techniques regarding the complications. The mean operation time was 150 ± 23.7 and 133 ± 23.12 min in ST and LIT, respectively, and the difference was statistically significant. Both ST and LIT are safe techniques with a relatively low complication rate. However, ST can be effectively replaced by LIT because of its shorter operative time.

- Abstract
Background: Fine-needle aspiration (FNA) is a simple, safe, inexpensive, and acceptable method for diagnosing masses, especially at superficial areas. Therefore, we decided to evaluate the accuracy of FNA cytological diagnosis in nonthyroidal, nonsalivary gland neck masses and compare the results with histopathological diagnosis., Materials and Methods: In this retrospective study, all cases with FNA cytological diagnosis of nonthyroidal, nonsalivary gland neck masses from April 2009 to July 2013 were retrieved. The procedure was done by pathologists, and all cytological and histopathological slides of the existing 46 cases were reviewed by 3 pathologists. The values of sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated., Results: SN, SP, PPV, NPV, and accuracy in this study were 79, 100, 100, 73, and 86%, respectively. We had 6 false-negative and no false-positive cases., Conclusion: The FNA procedure is a reliable method as the first step for the diagnosis of nonthyroidal, nonsalivary gland neck masses. To increase the diagnostic value of cytology, careful examination of all cytological slides, repetition of the FNA procedure and good history taking are helpful., (© 2015 S. Karger AG, Basel.)

- Abstract
Objectives: The primary goal of this study was to evaluate the incidence and characteristics of posttraumatic headache attributed to mild brain injury in military personnel in Iran within a prospective and observational study design., Methods: A prospective observational descriptive study was conducted with a cohort of military personnel under military education during a 6-month period at the Military Education Center in Isfahan, Iran. 322 military personnel under education were selected randomly and were given a 13-item mild brain injury questionnaire accompanied with affective disorders and headache questionnaires and were reevaluated after a 3-month interval., Results: A total of 30 (9.3 %) of the 322 military personnel met criteria for a mild brain injury. Among them, 18 personnel (60 %) reported having headaches during the 3-month reevaluation. PTHs defined as headaches beginning within 1 week after a head trauma were present in 5.6 % of military personnel under study during 6 months. In total, 67 % of posttraumatic headaches (PTH) were classified as migrainous or possible migrainous features. Patients with affective disorders such as posttraumatic stress disorder and depression were at a higher risk for developing PTH following mild brain injury (p < 0.05). PTH did not relate to demographic factors such as age or type of trauma., Conclusions: Posttraumatic headache attributed to mild brain injury is a common disorder in military personnel. Migrainous features are predominant among them in comparison with the general population. PTH is not related to a type of trauma, but has association with affective disorders.

- Abstract
Objective. This study aimed to identify the microorganisms of surface and depth of tonsils and whether these microorganisms bring the menace of bacteremia during tonsillectomy in the children under surgery. Materials and Methods. The culture specimens were taken from surface and depth of tonsil from the patients suffering from chronic tonsillitis at the time of operation. Also, 10 mL venous blood samples were taken 5 minutes before and after the operation for microbiological study. Results. According to the results, 112 (76.1%) and 117 (79.6%) cultures from surface and depth of tonsils represented multiple microorganisms, respectively. Besides, staphylococci coagulase positive was the most common organism in both surface and depth of tonsils. None of the preoperation blood cultures were positive, while 3 postoperation blood cultures (2.1%) were positive. Staphylococci coagulase negative and alpha hemolytic streptococcus were detected in 2 cases (1.4%) and 1 case (0.7%), respectively. Conclusion. In the present study, the two cultured sites were almost similar regarding the types of isolated microorganisms. Our results suggested that bacteremia might occur after tonsillectomy. Therefore, to avoid the possible dramatic outcomes after tonsillectomy, pre- and postoperation attendances are essential.

- Abstract
Introduction: The use of cartilage as a grafting material has been advocated in cases where there is a high risk of graft failure, such as subtotal perforations, adhesive processes, and residual defects after primary tympanoplasties. The purpose of this study was to compare the graft acceptance rates and auditory outcomes of cartilage tympanoplasty operations using a palisade technique with those of primary tympanoplasty using temporalis fascia in a homogenous group of patients., Study Design: Prospective study., Materials and Methods: The study population included 54 patients who were operated on in two groups (palisade technique & temporalis fascia technique) with each group containing 27 patients. Patients with pure subtotal perforations (perforation of >50% of the whole tympanic membrane [TM] area), an intact ossicular chain, at least a one month dry period, and normal middle ear mucosa were included in the study. Grafts acceptance rates and pre- and post-operative audiograms were compared. The follow-up time was six months., Results: Graft acceptance was achieved in all patients (100%) in the palisade cartilage tympanoplasty group and in 25 patients (92.5%) in the temporalis fascia group. This difference was not statistically significant (P= 0.15). Comparison of the increases in mean speech reception threshold, air-bone gap, and pure-tone average scores between both techniques showed no significant changes., Conclusion: Our experience with the palisade cartilage technique demonstrates that subtotal or total perforation at high risk for graft failure can be treated efficiently, and that a durable and resistant reconstruction of the TM with reasonable auditory function can be achieved.

- Abstract
Background: Otitis media with effusion is one of the leading causes of hearing loss in children. Effective treatment of effusion in the middle ear requires appropriate empirical treatment and characterization of responsible pathogens. Objective of the present study was to detect pathogens in clinical samples from patients with otitis media with effusion in our area and to determine the sensitivity profile of isolated organisms to commonly used antibiotics., Methods: Sixty three samples of middle ear effusion were aseptically obtained from 36 children, who had been treated up to at least two weeks before sampling. They were analyzed using standard bacteriological and multiplex polymerase chain reaction (PCR) assays. Antibiotic susceptibility tests were also performed., Results: PCR analysis showed that DNA of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were present in 60 (95.2%) of the samples. The culture-positive effusion for Streptococcus Pneumoniae, HaemophilusInfluenzae and Moraxella catarrhalis was 34.9%. Almost all isolates of Streptococcus pneumoniaee were sensitive to ciprofloxacin and erythromycin, and none of them was sensitive to co-trimoxazole. None of H. Influenzae isolates was sensitive to erythromycin, cefixim, co-trimoxazole, ampicillin and amoxicillin. None of M. Catarrhalis isolates was sensitive to ceftriaxone, co-trimoxazole, ampicillin and amoxicillin., Conclusion: Compared with other studies using PCR method, the number of H.influenza isolates was in higher in the present study (95.2%). Antibiotic sensitivity profiles of pathogens isolated in this study were different from others. Thus, we can determine empirical antibiotic therapy based on sensitivity profile in our geographic area.

- Abstract
Background: Actinomycosis of the tonsils has been reported in a variable percentage of tonsil specimens by other authors. This study determines the incidence of actinomyces in the palatine tonsil and evaluates the clinical diagnoses and histopathological features of tonsillectomy specimens., Methods: In a retrospective study, 204 patients who had undergone tonsillectomy for recurrent tonsillitis (group A) and for sleep apnea without a history of recurrent tonsillitis (group B) were enrolled., Results: The prevalence rate was significantly higher in the adult compared with the pediatric population. The prevalence of tonsillar actinomycetes colonization was higher in patients who had undergone tonsillectomy for recurrent tonsillitis (43.9%) than in patients who had undergone tonsillectomy for obstructive sleep apnea (26.3%). The prevalence did not differ by sex of patient. Histopathological analysis of resected tonsils did not show active tissue infection. There was a statistically significant relationship between the presence of actinomycosis and age, with a greater occurrence of actinomycosis in adult patients., Conclusion: Although actinomyces colonization is more prevalent in patients with recurrent tonsillitis than sleepdisordered breathing, but the presence of actinomyces does not indicate any active disease.

- Abstract
Tumors of the salivary glands are uncommon head and neck neoplasia. We conducted a retrospective study of 392 cases over the last 6 years in Shiraz, south of Iran, to investigate the clinicopathological features of these tumors in Iranian population. The age of the patients ranged from 8 to 85 years, with the mean age 44.57 ± 14.65 years and male-to-female (M : F) ratio was 1.02 : 1. For benign tumors, there was a propensity towards females, whereas the malignant tumor was more common in males. The ratio of benign tumors to malignancies was 2.19 : 1. Pleomorphic adenoma (PA) was the most common tumor and accounted for 85% of all benign tumors, followed by Warthin's tumor (8.6%). Of the 125 malignancies, adenoid cystic carcinoma (40%), mucoepidermoid carcinoma (24%) and invasive squamous cell carcinoma (16%) were the most common histological types. Most of the salivary gland tumors (75%) originated from major salivary glands and the remained (25%) originated from minor glands. The parotid gland was the most common site both in benign and malignant tumors. Most of our findings were similar to those in the literature, with some variations. The salivary tumors slightly predominated in males. Adenoid cystic carcinoma and mucoepidermoid carcinoma constituted the most common malignancies.

- Abstract
Objective: The thalassemias are among the most common genetic disorders worldwide, occurring more frequently in the Mediterranean region. The aim of this study was to determined frequency of sensory-neural hearing loss in major ß- thalassemias transfusion dependent patients in south of Iran., Methods: A cross sectional study on 308 cases of major beta-thalassemia patients referring to Thalassemia Center of Shiraz University of Medical Sciences between 2006-2007 years. The diagnosis of ß- thalassemia major was based on clinical history, complete blood count and hemoglobine electrophoresis. Clinical data such as serum ferritin level, deferoxamine (DFO) dose, mean daily doses of DFO (mg/kg) and audiometric variables was recorded., Findings: Out of 308 cases, 283 (96.5%) had normal hearing and 10 (3.5%) sensorineural hearing loss. There was no statically significant difference between two groups regarding mean age, weight, age at the first blood transfusion, age at the first DFO infusion., Conclusion: We found the lowest incidence of sensorineural hearing loss in a large population of patients suffered from major thalassemia who received DFO. We show that DFO is not ototoxic at a low dose. When considering all related literature, as a whole there has been much critical misrepresentation about DFO ototoxicity.

- Abstract
Objectives: To evaluate the effect of Donepezil on cerebral blood flow velocity using non-invasive transcranial Doppler (TCD) sonography., Methods: This clinical trial was carried out in the Department of Neurology, Alzahra Hospital, Isfahan University of Medical Sciences, Isfahan, Iran from March 2008 to July 2009, on Alzheimer's disease (AD) patients in 2 groups of case and control, each consisting of 11 patients. The case group who received Donepezil medication was examined by TCD before (baseline), after 4 weeks of oral treatment with 5 mg per day Donepezil, and a further 4 weeks of 10mg per day Donepezil, orally. The control group comprised AD patients who did not receive any medications, and were examined by TCD only once. Peak systolic (PSV), end-diastolic (EDV), and mean flow (MFV) velocities of the posterior cerebral artery (PCA) and the middle cerebral artery (MCA) was assessed by TCD. Also, mini-mental state examination (MMSE) was carried out., Results: There were no significant differences between the case and control groups, in terms of age and gender. In the case group, the mean MMSE score reached 20.2 +/- 2.8 from a baseline value of 15.8 +/- 3.3 after 4 weeks of oral treatment with 5 mg/d Donepezil, and reached 20.6 +/- 3.9 after 4 more weeks at 10 mg/d Donepezil. In the MCA, the difference in PSV and MFV values after 4 weeks of treatment with 10 mg/d Donepezil was statistically significant compared with the baseline values. In PCA, the values of MFV and EDV after 4 weeks of treatment with 10 mg/d Donepezil were statistically significant in comparison with the baseline value., Conclusion: Donepezil (10 mg/d) increased cerebral blood flow velocity and MMSE score in our AD patients, but more extensive trials are recommended.

- Abstract
Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon vascular inflammatory lesion usually involving the dermis or subcutaneous tissue of the head-neck region of middle-aged women. Histologically, this lesion shows a florid proliferation of vessels lined by particular endothelial cells and an inflammatory infiltrate composed of lymphocytes and eosinophils., Case: A 30-year-old woman presented with multiple periauricular skin nodules. Fine needle aspiration cytology shows a mixed population of lymphoid cells with an admixture of eosinophils and large cells with vesicular nuclei and prominent nucleoli. A diagnosis of AHLE was confirmed on histopathologic examination., Conclusion: Various conditions, both benign and malignant, may mimic Kimura's disease clinically and on smears. These must be ruled out before making a diagnosis of Kimura's disease. The cytologic features of Kimura's disease have to be interpreted in the appropriate clinical setting in order to make a correct preoperative diagnosis.

- Abstract
Background: Malignant changes in pleomorphic adenoma (PA) of the salivary gland (carcinoma ex pleomorphic adenoma) are not common. Clear cell carcinoma is a rare form of salivary gland tumor and involves mostly minor salivary glands, especially those of the palate. Only 3 cases of clear cell carcinoma arising in PA have been reported, 2 in submandibular glands and 1 in a minor salivary gland of the palate., Case: A 53-year-old man presented with an enlarged mass on the left side of the palate. He had a history of palate mass about 30 years earlier; it was excised and reported as PA. Since then the tumor had recurred twice in the same place; it had been excised and was diagnosed as PA again. A few years later the mass showed rapid growth over a few months. Fine needle aspiration of the mass showed epithelial clusters with bland nuclear features and myxohyaline material typical of PA. Also noted were large and small papillary, trabecular and well-circumscribed clusters of neoplastic cells with a moderate amount offoamy, vacuolated cytoplasm with distinct borders. Glandlike and acinar structures with hyaline globule material resembling cannonballs were also noted. The cytology was suspicious for malignancy. Incisional biopsy was reported as PA. Due to the suspicion of malignancy, the whole mass was excised up to the floor of the orbit. The final diagnosis was clear cell carcinoma expleomorphic adenoma., Conclusion: Due to nonspecific cytologic findings in clear cell carcinoma and a mixture of elements of PA in this case, we did not consider clear cell carcinoma as the malignant component.
