Abstract
Background and Aim: Total laryngectomy following laryngeal cancer has many sequelae , that loss of voice is the most important of them. Tracheoesophageal puncture (TEP) and prosthesis insertion has evolved into the most widely used and accepted technique for vocal rehabilitation.
Materials and Methods: 10 patients that underwent TEP in Amir Alam and Imam Khomeini hospitals from Feb. 2002 through Nov. 2003 were included in this study. Prosthesis insertion in 4 patients is primary and in 6 patients is secondary and all patients are men.
Results: The age of patients was between 50 to 70. 90% of patients had history of cigarette smoking and 10% of them had history of drinking alcohol. Salivary leakage was seen in 30% of patients that was improved with conservative management. Fluency of speech in 30% of patients and intelligibility of speech & voice quality in 40% of patients is good.
Conclusion: We could conclude that TEP has less complication & better speech results of other vocal rehabilitation methods. Carefully selection of patients & size of prosthesis has important role in results of TEP.

Abstract
Background: Multiple sclerosis (MS) is a chronic disease that begins most commonly in young adults and is characterized pathologically by multiple areas of central nervous system (CNS) white matter inflammation, demyelination, and glial scarring. The most valuable aid for diagnosis is magnetic resonance imaging (MRI). New type of MRI has been developed on the basis of molecular diffusion which capable of detecting acute and active lesions. Early diagnosis and treatment is possible to stop or slow down progression of disease. The aim of this study is to compare the findings of conventional and diffusion- weighted (DW) MRI in detection cerebral lesions of MS.
Methods: Thirty patients with clinically definite MS and 30 healthy volunteers were studied in a descriptive-prospective survey over a twelve-month period of time. Conventional and DW MRI were used in both groups. Total number, morphology, location and the mean size of the intra-cerebral plaques of MS were compared between group. The sensitivity and the specificity of both imaging methods in detecting these plaques were determined.
Results: Thirty patients with MS with the mean age of 32.76±8.79 years and 30 healthy individuals with the mean age of 32.75± 9.23 years were enrolled. Plaque within the brain was significantly higher by the conventional method (P< 0.05). Ovoid lesions were greater in number in the conventional method group. More lesions were detected by the conventional method in the areas of periventricle, centrum semiovale and corpus callosum. Regarding the size of plaque, the minimum measurement was significantly lower in the conventional method group. The sensitivity of both methods was 100%. The specificity of conventional and DW MRI was 86.6% and 96.6%, respectively.
Conclusion: In our study the sensitivity of both methods was the same but the specificity of DW MRI was higher. DW MRI may detect lesions which are not detectable by the routine methods.

Abstract
Background: Radiofrequency has recently been used in treating tonsilar hypertrophy in adults. We evaluated the results of partial resection (volume reduction) of tonsil using this method.
Methods: Twenty patients with tonsilar hypertrophy were enrolled in a quasi-experimental before-after clinical trial. Local anesthesia was achieved by utilizing lidocain spray and then injection of lidocain and epinephrine, then radiofrequency was performed at power=7-8w. Bleeding, pain and need for analgesics were assessed during, immediately, 4, 6, and 8 weeks after operation.
Results: The mean pain scale was 2.68±2.11 according to (VAS) and the mean bleeding amount was 1.16±0.24ml during operation. The mean operation time was 7.81±2.56min. Ten percent of our patients did not have pain immediately after surgery while 55% complained of pains that did not warrant using analgesics and the remaining 35% experienced pains that were alleviated by analgesics. During and immediately after operation 95% of the patients experienced mild bleeding and only one patient (5%) had moderate bleeding (2-5ml). Mild bleeding was only reported in 10% of patients during the first 4 weeks after operation and was not seen in patients in following weeks. The grade of tonsilar hypertrophy decreased in all patients and the mean time of symptom disappearance was 7.81±0.36 in 8 weeks. Finally the mean satisfaction rate of the patients was 66.92±12.5% (ranging from 50% to 80%). Mild complications were reported in 15% of patients.
Conclusion: Radiofrequency is a safe procedure with minimum possible complication rate for tonsilotomy.

Abstract
Background: Resulting from the rough flow of air through the nose and throat during sleep, snoring can arise from transitory obstruction at various levels, rendering the sufferer feeling sleep deprived. A relatively new method using radiofrequency technology, called palatoplasty (somnoplasty), can be used to reduce the size of obstructive tissues in the nose and throat. In this study, we assess radiofrequency palatoplasty in the treatment of snoring.
Methods: This nonrandomized prospective quasi-experimental study included 28 patients who snored at a level considered bothersome to their bed partner. Snoring and drowsiness were each subjectively scored using 20-point visual analogue scales before and after treatment. Radiofrequency energy was delivered to the soft palate either at the midline or in the lateral soft palate 21 patients were treated once and seven patients twice with an interval of at least seven weeks.
Results: The mean age of the patients was 47 (SD=10.7) years, with a range of 25-65 years, 57% were men, and the mean body mass index was 29 (SD=4.5). Sleep apnea in these patients was subjectively rated mild to moderate. After seven weeks of treatment, snoring was improved in 71.4% of patients (p<0.005). The tongue versus pharyngeal size was improved in 34.4% (p<0.005). The mean patient snoring score was significantly improved from 17.39 (SD=3.02) to 11.50 (SD=6.46) (p<0.005). The mean drowsiness score was also significantly reduced from 6.8 (SD=6.9) to 3.93 (SD=4.19) (p<0.005). No persistent negative impact was observed in speech or swallowing. Pain and bleeding was limited.
Conclusions: Radiofrequency palatoplasty is effective in the treatment of snoring and its consequent drowsiness.

Abstract
Background: Urinary tract infection 0 in children causes renal scarring and permanent damage to the organ. In this study, we compared the diagnostic value of magnetic resonance urogram for urinary tract anomalies with other conventional imaging methods in children with UTI.
Methods: In this case-control study, 190 children (mean age 3.23±3.59 yrs) with UTI were recruited from the Pediatric Ward of Rasul-e-Akram Hospital during 2007-2009. The patients were divided into two groups based on the applied imaging technique: MRU (cases) and conventional imaging groups (controls).
Results: Abnormal imaging detection rates for Ultrasonography were 32%, X-ray of kidneys, ureters and bladder (KUB) 9%, Intravenous Pyelogram (IVP) 26%, Voiding Cystoure therogram (VCUG) 54%, Dimercaptosuccinic Acid scan (DMSA) indicating
non-obstructive (reflux) uropathy in 76% (mean age 3.5 yrs) and MRU 43% (mean age
1.6 yrs), respectively. A meaningful correlation was observed between MRU and DMSA scan with IVP results (Kappa=0.75). KUB and Ultrasonography had similar results in cases with abnormal MRU and DMSA scan (P=0.121). MRU had strong agreement with VCUG and IVP for the detection of obstructive uropathy and scar due to congenital malformation even during intrauterine life but not with sonography results.
Conclusion: Sonography had poor results for the diagnosis of urinary tract anomalies in comparison with MRU. Use of dynamic MRU for the diagnosis of congenital anomalies (hydronephrosis, obstruction, pyelonephritis, renal scar) in children with UTI seems to be of better help, although higher costs and the need for sedation during MRU still are its disadvantages

Abstract
Background: Recent studies have indicated the relation of vertebral endplate lesions (Modic changes) to low back pain (LBP). The aim of this study was to investigate the Modic changes in magnetic resonance imaging (MRI) of patients with low back pain, and its correlation with age, sex, type of changes, number of involved segments and location of changes. Additionally, association of degenerative disc changes and disc herniation was assessed.
Methods: In this retrospective study, MRI records of 229 patients with LBP referring to Medical Center of Hazrat-e-Rasoul Hospital, Tehran, Iran, from August to February 2014, were assessed and Modic changes and degenerative and herniated disc changes were recorded.
Results: Based on our observations, a significant association between Modic type and age (P= 0.003) existed in patients with LBP. The highest prevalence in Modic location were observed in anterior part of vertebral endplate (48.8%, P= 0.001). Although, observation of the Modic changes in superior vertebral endplate was higher than inferior parts, but this differences was not statistically significant. The highest prevalence in degenerative disc disease was disc dehydration which was observed in 18.1% of patients (P= 0.04). The relationship between the degenerative changes and Modic type was significant (P= 0.04), while the most prevalent change of disc contour was disc bulging which occurred in 23.7% of patients (P= 0.01). The highest frequency of abnormal disc contour were observed in Modic type 2 which was statistically significant (P= 0.01). Modic surface involvement above 25% was significantly associated with disc herniation (P= 0.04). There was no significant association between Modic height involvement above 25% and disc herniation.
Conclusion: Considering significant association between Modic changes and degenerative and herniated disc changes, reporting of Modic changes is necessary.

Abstract
Background: Helicobacter pylori infection and respiratory tract infection at the same time cause pathogenicity increase and death. The aim of this study was to evaluate the co-occurrence of upper respiratory tract disorders and gastrointestinal infections of H. pylori.
Methods: The present study was conducted as a systematic review and meta-analysis, from August 2019 to Agusut 2020, at Qazvin University of Medical Sciences. Articles in the international databases (April 2001-December 2018) on the coexistence of upper respiratory tract disorders with H. pylori gastrointestinal infections were examined. The random effect model with a 95% confidence level was used to analyze the data.
Results: The highest prevalence of respiratory disorders co-occurrence associated with adenoid tissue (33%), nasal polyps (100%), chronic rhinosinusitis (71%) and gastrointestinal infections of H. pylori was reported in 2006 in Turkey, 2011 in Poland and 2015 in Egypt. Concurrent prevalence of the disease, according to the type of upper respiratory tract disorders in all studies, the estimated effect size according to the random model was 53% in chronic rhinosinusitis, 63% in nasal polyps, 62% in adenoid tissue and 60% in total, which was significant (P=0/000). The prevalence of co-occurrence of upper respiratory tract disorders with gastrointestinal infections of H. pylori in patients was estimated to be 61% at the age of more than 27 years and 60% at the age of fewer than 27 years. Pooled estimation of the concurrent prevalence of infection (in total) was estimated to be 60% and was significant among the studies (P=0/000).
|
Conclusion: The concurrent prevalence of upper respiratory tract disorders with gastrointestinal infections of H. pylori was observed to be almost equal and significant in elderly and young patients. Due to the fact that the simultaneous occurrence of two types of infections and diseases in people is very dangerous, screening of patients with each of these infections is necessary to identify the other infection and prescribe appropriate drugs.
