Abstract
BACKGROUND Mucolipidosis type IV (MLIV) is a rare, progressive lysosomal storage disorder characterized by severe intellectual disability, delayed motor milestones and ophthalmologic abnormalities. MLIV is an autosomal recessive disease caused by mutations in the MCOLN1 gene, encoding mucolipin-1 which is responsible for maintaining lysosomal function. OBJECTIVES AND METHODS Here, we report a family of four Iranian siblings with cognitive decline, progressive visual and pyramidal disturbances, and abnormal movements manifested by severe oromandibular dystonia and parkinsonism. MRI scans of the brain demonstrated signal abnormalities in the white matter and thinning of the corpus callosum. RESULTS AND CONCLUSIONS Whole-exome sequencing identified a novel homozygous variant, c.362C > T:p. Thr121Met in the MCOLN1 gene consistent with a diagnosis of MLIV. The presentation of MLIV may overlap with a variety of other neurological diseases, and genetic analysis is an important strategy to clarify the diagnosis. This is an important point that clinicians should be familiar with. The novel variant c.362C > T:p. Thr121Met herein described may be related to a comparatively older age at onset. Our study also expands the clinical spectrum of MLIV associated with the MCOLN1 variants and introduces a novel likely pathogenic variant for testing in MLIV cases that remain unresolved.

Abstract
BACKGROUND Olfaction has recently found clinical value in prediction, discrimination and prognosis of some neurodegenerative disorders. However, data originating from standard tests on olfactory dysfunction in Huntington's disease are limited to odour identification, which is only one domain of olfactory perceptual space. METHOD Twenty-five patients and 25 age- and gender-matched controls were evaluated by the Sniffin' Sticks test in three domains of odour threshold, odour discrimination, odour identification and the sum score of them. Patients' motor function was assessed based on the Unified Huntington's Disease Rating Scale. RESULTS Compared with controls, patients' scores of all olfactory domains and their sum were significantly lower. Besides, our patients' odour threshold and odour discrimination impairments were more frequently impaired than odour identification impairment (86 per cent and 81 per cent vs 34 per cent, respectively). CONCLUSION Olfactory impairment is a common finding in patients with Huntington's disease; it is not limited to odour identification but is more pronounced in odour discrimination and odour threshold.

Abstract
BACKGROUND The unique neurovascular structure of the retina has provided an opportunity to observe brain pathology in many neurological disorders. However, such studies on neurodegeneration with brain iron accumulation (NBIA) disorders are lacking. OBJECTIVES To investigate NBIA's neurological and ophthalmological manifestations. METHODS This cross-sectional study was conducted on genetically confirmed NBIA patients and an age-gender-matched control group. The thickness of retinal layers, central choroidal thickness (CCT), and capillary plexus densities were measured by spectral domain-optical coherence tomography (SD-OCT) and OCT angiography, respectively. The patients also underwent funduscopy, electroretinography (ERG), visual evoked potential (VEP), and neurological examination (Pantothenate-Kinase Associated Neurodegeneration-Disease Rating Scale [PKAN-DRS]). The generalized estimating equation model was used to consider inter-eye correlations. RESULTS Seventy-four patients' and 80 controls' eyes were analyzed. Patients had significantly decreased visual acuity, reduced inner or outer sectors of almost all evaluated layers, increased CCT, and decreased vessel densities, with abnormal VEP and ERG in 32.4% and 45.9%, respectively. There were correlations between visual acuity and temporal peripapillary nerve fiber layer (positive) and between PKAN-DRS score and disease duration (negative), and scotopic b-wave amplitudes (positive). When considering only the PKAN eyes, ONL was among the significantly decreased retinal layers, with no differences in retinal vessel densities. Evidence of pachychoroid was only seen in patients with Kufor Rakeb syndrome. CONCLUSION Observing pathologic structural and functional neurovascular changes in NBIA patients may provide an opportunity to elucidate the underlying mechanisms and differential retinal biomarkers in NBIA subtypes in further investigations. © 2023 International Parkinson and Movement Disorder Society.

Abstract
BACKGROUND Olfactory dysfunction has been suggested as a diagnostic and discriminative biomarker in some neurodegenerative disorders. However, there are few studies regarding the olfactory status in rare diseases including neurodegeneration with brain iron accumulation (NBIA) disorders. METHODS Genetically-confirmed NBIA patients were enrolled. Neurological and cognitive examinations were conducted according to the Pantothenate Kinase-Associated Neurodegeneration-Disease Rating Scale (PKAN-DRS) and the Mini-Mental State Examination (MMSE) questionnaire, respectively. Olfaction was assessed in three domains of odor threshold (OT), odor discrimination (OD), odor identification (OI), and total sum (TDI) score by the Sniffin' Sticks test. The olfactory scores were compared to a control group and a normative data set. RESULTS Thirty-seven patients, including 22 PKAN, 6 Kufor Rakeb syndrome, 4 Mitochondrial membrane Protein-Associated Neurodegeneration (MPAN), 5 cases of other 4 subtypes, and 37 controls were enrolled. The mean PKAN-DRS score was 51.83±24.93. Sixteen patients (55.2%) had normal cognition based on MMSE. NBIA patients had significantly lower olfactory scores compared to the controls in TDI and all three subtests, and 60% of them were hyposmic according to the normative data. Including only the cognitively-normal patients, still, OI and TDI scores were significantly lower compared to the controls. The phospholipase A2-Associated Neurodegeneration (PLAN) and MPAN patients had a significantly lower OI score compared to the cognitively-matched PKAN patients. CONCLUSION Olfactory impairment as a common finding in various subtypes of NBIA disorder can potentially be considered a discriminative biomarker. Better OI in PKAN compared to PLAN and MPAN patients may be related to the different underlying pathologies.

Abstract
BACKGROUND Transcranial Sonography is a non-invasive technique that has been used as a diagnostic tool for a variety of neurodegenerative disorders. However, the utility and potential application of this technique in NBIA disorders is scarce and inconclusive. METHODS In this cross-sectional retrospective case-control study, the echogenicity of Substantia Nigra (SN), Lentiform Nucleus (LN), and Diameter of the Third Ventricle (DTV) were assessed by TCS in genetically confirmed NBIA patients referring to the movement disorder clinic. The normal echogenicity area of SN was defined based on the 90th percentile of an age-and-gender-matched control group. NBIA patients underwent neurologic examination at each visit, but their brain magnetic resonance imaging and demographics were extracted from electronic records. RESULTS Thirty-five NBIA patients of four subtypes with a mean disease duration of 10.54 years and 35 controls were enrolled. The normally defined SN echogenicity in controls was 0.23 cm2. DTV and SN echogenicity areas were significantly higher in patients compared to the controls (P = 0.002 and < 0.001, respectively). Around 85% and 63% of the patients showed LN and SN hyperechogenicity at least on one side, respectively. Disease duration was positively correlated with DTV (r = 0.422, p = 0.015). Cases with Pantothenate Kinase Associated Neurodegeneration (n = 23) also had significantly higher DTV and SN echogenicity area compared to the controls. CONCLUSION Despite most NBIA patients displayed increased DVT and higher SN and LN hyperechogenicity than healthy controls, the discriminatory role of TCS on different NBIA subtypes remains to be determined.

Abstract
BACKGROUND Neurodegeneration with Brain Iron Accumulation (NBIA) disorder is a group of ultra-orphan hereditary diseases with very limited data on its course. OBJECTIVES To estimate the probability of preserving ambulatory ability and survival in NBIA. METHODS In this study, the electronic records of the demographic data and clinical assessments of NBIA patients from 2012 to 2023 were reviewed. The objectives of the study and factors impacting them were investigated by Kaplan-Meier and Cox regression methods. RESULTS One hundred and twenty-two genetically-confirmed NBIA patients consisting of nine subtypes were enrolled. Twenty-four and twenty-five cases were deceased and wheelchair-bound, with a mean disease duration of 11 ± 6.65 and 9.32 ± 5 years. The probability of preserving ambulation and survival was 42.9% in 9 years and 28.2% in 15 years for classical Pantothenate Kinase-Associated Neurodegeneration (PKAN, n = 18), 89.4% in 7 years and 84.7% in 9 years for atypical PKAN (n = 39), 23% in 18 years and 67.8% in 14 years for Mitochondrial Membrane Protein-Associated Neurodegeneration (MPAN, n = 23), 75% in 20 years and 36.5% in 33 years for Kufor Rakeb Syndrome (KRS, n = 17), respectively. The frequencies of rigidity, spasticity, and female gender were significantly higher in deceased cases compared to surviving patients. Spasticity was the only factor associated with death (P value = 0.03). CONCLUSIONS KRS had the best survival with the most extended ambulation period. The classical PKAN and MPAN cases had similar progression patterns to loss of ambulation ability, while MPAN patients had a slower progression to death. Spasticity was revealed to be the most determining factor for death.

Abstract
BACKGROUND Novel biomarkers have been suggested for the diagnosis and prognosis of diabetes mellitus. The biomarker utility of netrin-1 in diabetes as an extracellular protein has been investigated. In this systematic review and meta-analysis, we reviewed the role of netrin-1 as a biomarker in prediabetes, diabetes, and complications of diabetes. METHODS PubMed, Embase, Scopus, and Web of Science were systematically searched for studies that measured circulatory and/or urinary netrin-1 levels in diabetes and compared them with non-diabetic patients or evaluated the prognostic role of this marker. Standardized mean difference (SMD) and 95% confidence interval (CI) were calculated using random-effect meta-analysis to compare netrin-1 levels between groups. The impact of mean age, male sex percentage, sample size, mean body mass index, and publication year on the overall heterogeneity was assessed using meta-regression. RESULTS Among 413 records from international databases, 19 original studies were included with 2061 cases (1137 diabetics, 196 prediabetics, and 728 healthy controls). Meta-analysis of eight studies measuring netrin-1 in patients with diabetes and comparing it with healthy controls showed no significant difference between the two groups (SMD 0.69, 95% CI -0.78 to 2.16, I2 = 98%, p-value = 0.36). On the other hand, a meta-analysis of netrin-1 levels in patients with prediabetes in comparison with healthy controls revealed that they had lower levels (SMD -0.51, 95% CI -0.81 to -0.21, p-value < 0.01). Diabetic patients with microalbuminuria and macroalbuminuria had significantly higher circulatory netrin-1 levels compared to normoalbuminuric group SMD 1.18, 95% CI 0.83 to 1.53, p-value < 0.01 and SMD 1.67, 95% CI 0.76 to 2.58, p-value < 0.01, respectively). Moreover, no difference in urinary netrin-1 levels was found between micro-, macro-, and normoalbuminuric groups (p-value > 0.05). CONCLUSION Netrin-1 showed promising results as a biomarker in diabetes prognosis. However, more studies are required to confirm our findings, and higher sample size studies are needed to evaluate the diagnostic utility of this marker.

Abstract
This study was done to find exopolysaccharide (EPS)-producing lactic acid bacteria (LAB) against foodborne pathogens. Isolated LAB were screened to find the ones with the ability to produce antibacterial EPS against foodborne pathogens. Among tested EPSs, EPS of AS20(1) isolate showed inhibitory effects on the growth of Listeria monocytogenes (MIC = 0·935 mg ml-1 , MBC = 0·935 mg ml-1 ), Yersinia enterocolitica (MIC = 12·5 mg ml-1 , MBC = 50 mg ml-1 ) and Bacillus cereus (MIC = 6·25 mg ml-1 , MBC = 12·5 mg ml-1 ). According to 16S rRNA sequencing, AS20(1) showed the closest similarity to Lacticaseibacillus paracasei (100%). This antibacterial EPS showed negligible toxicity (4·4%-5·2%) against red blood cells. Lacticaseibacillus paracasei AS20(1) showed probiotic properties, including high acid resistance, hydrophobicity (47·5%), autoaggregation and coaggregation with foodborne pathogens. Also, L. paracasei AS20(1) showed no haemolysis activity and antibiotic resistance. Characterization of antibacterial EPS revealed that it is a heteropolysaccharide with various functional groups, amorphous structure, and smooth surface, sheet and compact structure, which can be suitable for food packaging. L. paracasei AS20(1) and its antimicrobial EPS can be used to make functional food.

Abstract
Post-traumatic olfactory dysfunction (PTOD) is associated with a significant decrease in quality of life. The present study aimed to explore whether PTOD is associated with depression and changes in sexuality. There were two groups in this case-control study. The patient group consisted of patients with PTOD (n = 55), and the control group comprised healthy individuals without the olfactory disorder (n = 115). Olfactory function, depression, partnership, and sexual satisfaction were assessed using the Iranian version of the Sniffin' Sticks test (Ir-SST), Beck Depression Inventory (BDI), Enrich Couple Scale (ECS) and Sexual Satisfaction Scale for Women (SSSW). The BDI scores were higher in the patient group than in the control group (p < 0.001). The SSSW score was lower in the patient group than in controls (p < 0.01), although the ECS score was not significantly different between patients and controls. Also, there was no significant difference in the severity of trauma between marital satisfaction and sexual satisfaction. However, the analysis showed a statistically significant difference in depression scores in connection with the head trauma severity. In the PTOD group, depression was increased and sexual satisfaction declined. Understanding the association of olfactory dysfunction with depression and sexuality allows patients and doctors to deal with less notable consequences of this disorder.

Abstract
OBJECTIVE This study aimed to measure the duration and recovery rate of olfactory loss in patients complaining of recent smell loss as their prominent symptom during the coronavirus disease 2019 outbreak. METHOD This was a prospective telephone follow-up observational study of 243 participants who completed an online survey that started on 12 March 2020. RESULTS After a mean of 5.5 months from the loss of smell onset, 98.3 per cent of participants reported improvement with a 71.2 per cent complete recovery rate after a median of 21 days. The chance of complete recovery significantly decreased after 131 days from the onset of loss of smell (100 per cent sensitive and 97.7 per cent specific). Younger age and isolated smell loss were associated with a rapid recovery, whereas accompanying rhinological and gastrointestinal symptoms were associated with longer loss of smell duration. CONCLUSION Smell loss, occurring as a prominent symptom during the coronavirus disease 2019 pandemic, showed a favourable outcome. However, after 5.5 months from the onset, around 10 per cent of participants still complained of moderate or severe hyposmia.

Abstract
In this report we have discussed our experience with a special home-made platelet-rich plasma (PRP)-fibrin glue (FG) as a last resort for treatment of a challenging case of postoperative CA. A 25 years old, ill woman was admitted with severe ascites and hepatic encephalopathy in our center. She was a known case of autoimmune hepatitis and cirrhosis who had undergone liver transplantation 5 years ago and developed chronic rejection. During the surgery an old organized thrombosis in the portal vein was detected, accordingly an iliac vein graft was used to bypass the superior mesenteric vein. After surgery the patient developed chylous ascites. Having no other choice, based on our experience with PRP-FG in similar situations, we decided to use this method as a last resort to treat postoperative chylous ascites. It can be concluded that when conservative management is not working for the treatment of postoperative chylous ascites in intractable cases, PRP-FG can be considered as a last resort treatment. A special home-made PRP-FG was prepared for the patient and of that, 90 mL was injected to the abdominal cavity via the drainage tube followed by a 25 mL of isotonic saline solution to prevent clot formation within the tube. Few days after treatment, chylous secretion decreased and then completely ceased. It can be concluded that when conservative management is not working for the treatment of postoperative chylous ascites in intractable cases, PRP-FG can be considered as a last resort treatment.

Abstract
Background: Papillary thyroid carcinoma (PTC) is considered the most frequent thyroid malignancy (85-90%) with a good prognosis. However, its frequent recurrence increases mortality and morbidity. In this inquiry we investigated the prevalence of risk factors of PTC recurrence and disease free survival after thyroidectomy and central neck dissection. Method: In this retrospective study, all patients with confirmed PTC who underwent total thyroidectomy and central neck dissection in Imam Reza and Omid hospitals of Mashhad University of Medical Sciences from 2004 to 2011 were included. Total locoregional and distant recurrence rate, 5-year disease free survival rate (DFS) and contributing factors of recurrence were investigated after at least 5 years. Results: In this study 289 patients were included with a mean follow-up of 72.90 ± 11.02 months. 70.6% were female and 29.4% were male. Recurrence occurred in 58 cases from which 10 were distant and 48 were loco-regional. 5-year DFS was 80% and total-survival-rate was 99%. Our analysis showed that primary tumor size, vascular-invasion, extra-thyroid extension, and lymph node ratio (LNR) were significantly related to DFS.

Abstract
Background: The outcome of congenital diaphragmatic hernia depends on associated anomalies, degree of pulmonary hypoplasia, and hypertension. We evaluated the postnatal prognostic factors which can be used to predict the outcome.Methods: This study was conducted at a tertiary center (Vali-e-Asr Hospital, Imam Khomeini Complex, Tehran, Iran) during 2013-2019. The predictors of survival were evaluated.Results: A total of 49 infants with congenital diaphragmatic hernia were born during 2013-2019. The patients’ mean gestational age and weight at birth were 37.51±1.75 weeks and 2871±562 g, respectively. The mortality rate in patients with surgery (n = 41) was 31.3% and eight patients died before surgery. Mortality had significant relationships with five-minute Apgar score, peak inspiratory pressure before and after surgery, partial pressure of arterial oxygen (PaO2), and pH during first 24 hours after birth (p= 0.01, 0.001, and 0.01, respectively). The predicted and true survival rates in the patients were 66% and 52%, respectively (p= 0.001).Conclusion: Predicting survival rate after birth is remarkable but controversial. This estimate should not affect patient care and should only help parents in the process of decision-making.

Abstract
Background & Objective Carbapenem-resistant Enterobacteriaceae is a growing concern worldwide including Iran. The emergence of this pathogen is worrying as carbapenem is one of the 'last-line' antibiotics for treatment of infections caused by multi drug resistant gram- negative bacteria. The main objective of this study was to determine the prevalence of carbapenem-resistant Enterobacteriaceae in a referral hospital in Tehran, Iran. Methods In this study, all positive isolates of Enterobacteriaceae recorded in blood, urine, and other body fluids were studied during April 2017 to April 2018 in a referral hospital in Tehran. All cases of resistance to carbapenems were first tested by modified Hodge test. All cases with positive or negative test, after gene extraction, were examined genotypically based on the primers designed for the three Klebsiella pneumoniae carbapenemase (KPC), New Delhi metallo-β-lactamase (NDM), and OXA-48 genes by conventional PCR method. Results 108 isolates (13.6%) were resistant to all cephalosporins as well as to imipenem and meropenem. In a genotypic study, including 45 isolates, 13 isolates were positive for OXA-48 gene, 11 isolates for OXA-48 and NDM genes, 11 isolates for OXA-48, NDM and KPC genes, 4 isolates for OXA-48 genes and KPC, 3 isolates for NDM, one isolate for KPC. On the other hand, two isolates were negative for all three genes examined. Conclusion OXA-48 gene was one of the most common genes resistant to carbapenems in Iran. According to studies, the prevalence of antibiotic resistance in Iran is rising dramatically, which reduces the choice of antibiotics to treat severe infections in the future.

Abstract
Background Healthcare-associated infections (HAIs) challenge modern medicine. Considering their high prevalence in Iran, we aimed to provide knowledge on the subject, and to teach about the importance of infection prevention and control (IPC) to a broad audience of pre-graduate healthcare professionals, focusing on education as the cornerstone of IPC. Main body We invited Iranian medical students to present ideas on “how to reduce HAIs.” Projects were eligible if being original and addressing the call. Accepted projects were quality assessed using a scoring system. Forty-nine projects were submitted, of which 37 met the inclusion criteria. They had a mean score of 69.4 ± 18.3 out of the maximum possible score of 115. Four reviewers assessed the 37 projects for clinical applicability, impact on patient safety, and innovation, and selected the best 12 to compete at the 2nd International Congress on Prevention Strategies for Healthcare-associated Infections, Mashhad, Iran, 2018. The competition took place in three rounds. The selected teams presented their projects in the first round and debated one by one in a knockout manner, while the jury reviewed their scientific content and presentation skills. In the second round, the top 5 projects competed for reaching the final stage, in which the teams presented their ideas in front of a panel of international IPC experts to determine the first three ranks. At the end of the contest, the participants gained valuable criticisms on how to improve their ideas. Moreover, by its motivating atmosphere, the contest created an excellent opportunity to promote IPC in medical schools. Conclusions Using innovation contests in pre-graduates is an innovative education strategy. It sensitizes medical students to the challenges of IPC and antimicrobial resistance and drives them to think about solutions. By presenting and defending their innovations, they deepen their understanding on the topic and generate knowledge transfer in both ways, from students to teachers and vice versa.

Abstract
OBJECTIVE Meningiomas comprise 6-15 % of cerebellopontine angle (CPA) tumors. Surgical treatment is a real challenge because this area is occupied by several critical neurovascular elements. Currently, surgery is the first choice of treatment, however several factors may be present that necessitate choosing the alternative treatments such as Gamma Knife Stereotactic Radiosurgery (GKS). PATIENTS AND METHODS Ninety-three patients with CPA meningioma who were treated by GKS for a period of 8 years, were retrospectively reviewed. Factors affecting clinical and radiological improvement were analyzed. RESULTS The median tumor volume was 6 cm3. The mean values for maximal and marginal dose were 20.2 and 13.6 Gy, respectively. The mean follow-up time was 31.5 months. Tumor control (lack of progression) was achieved in 96.8% of the patients and 55.9% of the patients showed tumor regression on follow-up MRI. The actuarial 3-year progression-free survival (PFS) rate was 96%. Clinical improvement was seen in 49.5% of the patients while 11.8% experienced worsening or new-onset symptoms. Adverse radiation effects were seen in 4.3% of the patients. A worse symptomatic outcome, male sex, a lower tumor coverage, and marginal doses <13.5 Gy were associated with worse radiologic outcomes. Worse radiologic outcomes and higher tumor volumes, especially tumor volumes ≥8.5 cc, were associated with worse symptomatic outcomes. The male sex was associated with a lower PFS. CONCLUSION Gamma Knife radiosurgery, either primarily or post- operatively, offers a decent long-term tumor control in CPA meningioma, and is associated with an acceptable complication profile, especially in tumors with lower volumes.

Abstract
Background Neonatal diabetes mellitus with hyperglycemia during the first 6 months of life is a rare disorder that can occur in all races and societies. Case presentation In this study, we introduced an Iranian (Persian) 65-day-old patient with neonatal diabetes mellitus with novel homozygous mutation in the pancreatic and duodenal homeobox 1, PDX1, gene, which is also known as IPF1 gene, located in exon 2. This case was a newborn boy born in Vali-Asr Hospital, Tehran; he was diagnosed as having hyperglycemia on 28th day. Genetic analysis detected a homozygous mutation on PDX1 gene on chromosome 13. It is a novel homozygous mutation in the PDX1 gene (NM_000209.3), p.Phe167Val. This mutation was confirmed by Sanger sequencing. There was no evidence of agenesis of the pancreas. Conclusions We reported a case of neonatal diabetes mellitus due to novel homozygous mutation in the PDX1 gene without exocrine pancreas manifestations.

Abstract
INTRODUCTION Processing odor information by the olfactory system depends greatly on the odor concentration. In order to use an odorant in a smell identification test (SIT), the minimum identification concentration (MIC) needs to be determined. MATERIALS AND METHODS This study was conducted in 60 healthy native individuals aged 20 to 60 years, selected from patients' companions in a tertiary hospital. In the first step, 25 odorants were presented to evaluate familiarity among the subjects. Then, the MICs for the eligible odorants were measured using the ascending method of limits. RESULTS Out of 25 odorants, only one (cacao) was distinguished by less than 70% of the subjects, and was therefore removed from the list. The MICs of the remaining 24 odorants ranged from 6.87±2.74% for menthol to 27.62±18.98% for cantaloupe. There was significant correlation between age and the MIC only for coffee (P=0.02, r=-0.300). There was a significant difference in MIC between men and women only for hazelnut (P=0.03). CONCLUSION We present the MICs of 24 culturally-familiar odorants in a sample of the Persian population in a SIT.

Abstract
Because of their great scientific and technological potentials, iron oxide nanoparticles (IONPs) have been the focus of extensive investigations in biomedicine over the past decade. Additionally, the surface plasmon resonance effect of gold nanoparticles (AuNPs) makes them a good candidate for photothermal therapy applications. The unique properties of both IONPs (magnetic) and AuNPs (surface plasmon resonance) may lead to the development of a multi-modal nanoplatform to be used as a magnetic resonance imaging (MRI) contrast agent and as a nanoheater for photothermal therapy. Herein, core-shell gold-coated IONPs (Au@IONPs) were synthesized and investigated as an MRI contrast agent and as a light-responsive agent for cancer photothermal therapy.The synthesized Au@IONPs were characterized by UV-visible spectroscopy, transmission electron microscopy (TEM), dynamic light scattering (DLS), and zeta potential analysis. The transverse relaxivity (r 2) of the Au@IONPs was measured using a 3-T clinical MRI scanner. Through a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, the cytotoxicity of the Au@IONs was examined on a KB cell line, derived from the epidermal carcinoma of a human mouth. Moreover, the photothermal effects of Au@IONPs in the presence of a laser beam (λ = 808 nm; 6.3 W/cm2; 5 min) were studied.The results show that the Au@IONPs are spherical with a hydrodynamic size of 33 nm. A transverse relaxivity of 95 mM-1 S-1 was measured for the synthesized Au@IONPs. It is evident from the MTT results that no significant cytotoxicity in KB cells occurs with Au@IONPs. Additionally, no significant cell damage induced by the laser is observed. Following the photothermal treatment using Au@IONPs, approximately 70% cell death is achieved. It is found that cell lethality depended strongly on incubation period and the Au@IONP concentration.The data highlight the potential of Au@IONPs as a dual-function MRI contrast agent and photosensitizer for cancer photothermal therapy.

Abstract
INTRODUCTION The Questionnaire for Olfactory Dysfunction (QOD) is a self-reporting olfactory-related quality of life questionnaire. The aim of this study was to determine the reliability and validity of the Persian version of this questionnaire. MATERIALS AND METHODS One hundred and thirteen patients with olfactory problems were enrolled in this study. The English version of the QOD was first translated into Persian. The reliability was then tested by determining the Cronbach alpha coefficient to assess internal consistency. The QOD was reviewed by a panel of experts, followed by calculating the content validity index to determine the content validity. RESULTS Based on the reliability analysis, the total Cronbach alpha was 0.88. The items in the "life quality" and "parosmia" domains had a good internal consistency in total, as well as in both genders and in different age subgroups. For the "sincerity" domain, however, low internal consistency was revealed (Cronbach alpha = 0.25). When questions related to the sincerity domain were omitted, the Cronbach alpha reached 0.89. The overall scale validity index for clarity and relevance were 0.88 and 0.87, respectively. CONCLUSION The Persian version of the QOD seems to be a reliable and valid tool for the assessment of quality of life in patients with olfactory dysfunction. The "sincerity" domain cannot be used separately or should be substantially modified in order to be applicable to the Iranian population. However, there is no need to change the whole format of the questionnaire.

Abstract
INTRODUCTION Vitamin D has been suggested to play a considerable role in the function of the immune system in various infectious, inflammatory, and autoimmune conditions. Otitis media with effusion (OME), defined as the presence of non-purulent fluid within the middle ear without signs or symptoms of suppurative otitis media, has a number of inflammatory predisposing factors. This study was designed to explore the association between vitamin D deficiency and OME. MATERIALS AND METHODS In this cross-sectional study, 74 children aged 2-7 years with an obstructive indication for adenotonsillectomy were included. Patients were divided into two groups based on the need for ventilation tube insertion for OME. Thirty-two children were enrolled in the OME group and 42 in the control group. The mean vitamin D level was compared between the two groups. RESULTS Mean vitamin D concentration in all patients was 11.96±5.85 ng/ml (9.79±4.36 ng/ml in the OME group and 13.61±6.33 ng/ml in the control group; P=0.003). There was also a significant difference in levels of vitamin D in patients referred in winter (9.0±2.94 ng/ml) compared with the summer (19.85±4.21 ng/ml; P=0.001). Data analyzed based on the season in which the patients were referred showed no significant difference between the OME and the control group. CONCLUSION Although our results showed lower serum levels of vitamin D in OME patients, the difference was not significant when seasons were taken into consideration. Therefore, the season is an important confounding factor in any research related to vitamin D due to the effect of sun-induced vitamin D.

Abstract
BACKGROUND Segmental pigmentation disorder (SegPD) is a rare type of cutaneous dyspigmentation. This hereditary disorder, first described some 20 years ago, is characterized by hypo and hyperpigmented patches on the trunk, extremities and less likely on the face and neck. These lesions are considered as a type of checkerboard pattern. CASE PRESENTATION Herein, we present a 26-year-old male who presented with hyperpigmented patches on his trunk, neck and upper extremities. Considering the clinical and histopathological findings, the diagnosis of SegPD was confirmed. CONCLUSION SegPD is a somewhat neglected entity which should be considered in differential diagnosis of pigmentation disorders.

Abstract
OBJECTIVE The aims of this study were to characterize the epidemiologic, histologic, and radiologic aspects of sphenopetroclival meningiomas (SpPCMs) and to evaluate the outcome of Gamma Knife radiosurgery (GKRS) either as an adjunct to microsurgery or as a primary SpPCM treatment modality. METHODS In this retrospective study, medical records of patients with SpPCM who underwent GKRS at the Iran Gamma Knife Center between April 2003 and March 2012 were analyzed. RESULTS We assessed 122 patients with SpPCMs, including 101 women and 21 men, aged 24-94 years. The mean tumor volume was 12.24 ± 9.30 mL. Patients received 22.32 ± 3.29 Gy and 13.18 ± 1.02 Gy maximal and average marginal dose of GKRS, respectively. The most common complaint was visual impairment, followed by facial sensory impairment and headache. The most frequently involved cranial nerves were III, IV, and VI in 72.1% of patients, followed by II in 52.9%, and V in 35.5%. After radiosurgery, headaches improved in 90.0%, diplopia in 75.0%, and ptosis in 63.0% of patients. On magnetic resonance imaging, tumor size was reduced, unchanged, or increased in 77, 44, and 1 patient, respectively. Progression-free survival at the 5-year follow-up was 56.6%. Younger age (hazard ratio = 0.972, P = 0.011) and lower tumor volume (hazard ratio = 0.959, P = 0.009) were the main prognostic factors for progression-free survival. CONCLUSION GKRS can be an effective alternative treatment for controlling the progression of SpPCM tumors, producing appropriate clinical outcomes and few complications.

Abstract
BACKGROUND Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects. METHODS In this prospective study, 43 patients with pituitary adenoma who were candidates for EETSA from March 2012 to October 2013 were enrolled. The patients were evaluated preoperatively using acoustic rhinometry and rhinomanometry (with/without the use of decongestant drops) and asked to complete the 22-Item Sinonasal Outcome Test (SNOT-22) questionnaire. The tests were repeated at one and three months postoperatively. The preoperative data were compared with the first and second postoperative ones using paired-sample t-test. RESULTS Without the use of decongestant drops, the total airway resistance increased significantly (p=0.016), and the nasal airflow decreased significantly (p=0.031) in the first postoperative evaluation. However, in the 3rd postoperative month, the difference was not significant. With the use of decongestant drops, the objective parameters showed no significant changes compared to preoperative data even at the first evaluation. The SNOT- 22 scores also did not differ significantly in 1st and 3rd postoperative months. The first postoperative SNOT-22 showed a strong correlation with the second minimal cross-sectional area on simultaneous evaluation, and with the preoperative total airway resistance. CONCLUSION EETSA has a transient adverse effect on the nasal patency that quickly improves, making it a safe approach for the sinonasal system. Rhinomanometry is the most sensitive test for detecting these nasal functional changes objectively.

Abstract
To evaluate the impact of nasoseptal flap (NSF) elevation on sinonasal quality of life (QOL) in patients with pituitary adenomas who underwent endoscopic endonasal trans-sphenoidal approach (EETSA), the data of 106 eligible patients were included from February 2011 to December 2014. The scores of Sinonasal Outcome Test (SNOT-22) Questionnaire were assessed in case (that received reconstruction with NSF) and control groups preoperatively as well as 1, 3, 6, and more than 12 months postoperatively. Nine most related sinonasal questions were evaluated separately (9Q). There were no significant inter-group differences in the mean SNOT-22, 9Q, and sense of taste/smell scores in preoperative and all postoperative assessments. Within each group, a significant improvement of SNOT-22 and 9Q scores were noted after 12 months of surgery compared to preoperative data. In the NSF group, comparison of the pre- and first postoperative evaluation revealed a significant deterioration in 9Q score (p = 0.007) and "sense of taste/smell" (p < 0.001) which both returned to baseline in the 3rd month. Patients who used nasal paper mask for more than 100 "hour-days" showed a better SNOT-22 scores at 1st (p = 0.04) and 3rd (p < 0.001) months after surgery. Patients with adrenocorticotropic hormone (ACTH) secretory adenomas showed significantly higher scores of SNOT-22 in all postoperative assessments compared to the others. Although nasal symptoms deteriorated at first postoperative month (compare to preoperative data) in the NSF group, no negative impacts on the sinonasal QOL was showed comparing to the control group. ACTH-secreting adenomas could be assumed as a risk factor for poorer sinonasal QOL in EETSA.

Abstract
OBJECTIVE To compare the erectile function (EF) and sexual desire (SD) in men after radical cystoprostatectomy (RCP) who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution. MATERIALS AND METHODS Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41) or orthotropic ileal neobladder substitution (n = 40). EF and SD were assessed using International Index of Erectile Function (IIEF) questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire. RESULTS Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006). At 12-month postoperative period, 4 (9.8 %) and 14 (35.0 %) patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006). Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8 %) and 7 (17.1 %) patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02). At 12-month follow up period 24.4 % of the ileal conduit and 45.0 % of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01). CONCLUSION When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

Abstract
AIM To investigate quality of life (QoL) domains with three forms of urinary diversions, including ileal conduit, MAINZ pouch, and orthotopic ileal neobladder after radical cystectomy in men with muscle-invasive bladder cancer. MATERIALS AND METHODS In a prospective study, 149 men underwent radical cystectomy and urinary diversion (70 ileal conduit, 16 MAINZ pouch, and 63 orthotopic ileal neobladder). Different domains of QoL, including general and physical conditions, psychological status, social status, sexual life, diversion-related symptoms, and satisfaction with the treatment were assessed using an author constructed questionnaire. Assessment was performed at three months postoperatively. RESULTS In questions addressing psychological status, social status, and sexual life, patients with continent diversion had a more favorable outcome (P = 0.002, P = 0.01, and P = 0.002, respectively). The rate of erectile dysfunction did not differ significantly between the three groups (P = 0.21). The rate and global satisfaction was higher with the MAINZ pouch (68.7%) and ileal neobladder (76.2%) as compared with the ileal conduit group (52.8%) (P = 0.002). CONCLUSION Continent urinary diversion after radical cystectomy provides better results in terms of QoL as compared with ileal conduit diversion.

Abstract
Background Respiratory failure is a major problem in neonatal medicine in all over the world and has different causes. Using mechanical ventilation is one of its major treatments. Objectives Different strategies have been expressed in this context, including high frequency mechanical ventilation. Patients and Methods This study is a prospective randomized clinical trial conducted on all newborns with respiratory failure hospitalized in the NICU of Tehran vali-asr Hospital during 2009.These patients were divided in to two groups through block Randomization method; conventional mechanical ventilation group and high frequency ventilation group. Results Intraventricular hemorrhage (IVH) and air leak (e.g. pneumothorax) were less in HFPPV group than conventional group (P = 0.012 and P = 0.038). The mean time needed for mechanical ventilation was lower in HFPPV group, but this difference was not statistically significant (P = 0.922). Needing to O2 in 28 days of age was almost equal in both groups (P = 0. 99). Mortality, and refractory hypoxia and PVL were lower in HFPPV group, but the difference was not statistically significant (P = 0.301, P = 0. 508, P = 0. 113). Conclusions Treatment of neonatal respiratory failure with high rate mechanical ventilation may reduce some complications.

Abstract
BACKGROUND Music is considered a subset of developmental supportive care. It may act as a suitable auditory stimulant in preterm infants. Also, it may reduce stress responses in autonomic, motor and state systems. OBJECTIVE To assess and compare the influence of lullaby and classical music on physiologic parameters. METHOD This is a randomized clinical trial with cross-over design. A total of 25 stable preterm infants with birth weight of 1000-2500 grams were studied for six consecutive days. Each infant was exposed to three phases: lullaby music, classical music, and no music (control) for two days each. The sequence of these phases was assigned randomly to each subject. Babies were continuously monitored for heart rate, respiratory rate, and oxygen saturation and changes between phases were analyzed. RESULT Lullaby reduced heart rate (p < 0.001) and respiratory rate (p = 0.004). These effects extended in the period after the exposure (p < .001 and p = 0.001, respectively). Classical music reduced heart rate (p = 0.018). The effects of classical music disappeared once the music stopped. Oxygen saturation did not change during intervention. CONCLUSION Music can affect vital signs of preterm infants; this effect can possibly be related to the reduction of stress during hospitalization. The implications of these findings on clinical and developmental outcomes need further study.

Abstract
This prospective study was designed to perform lamellar body count of amniotic fluid to evaluate fetal lung maturity. Lamellar body counts of 80 amniotic fluid samples from 80 pregnant women (28-40 weeks of gestation) were evaluated. After delivery, each infant was evaluated for any evidence of respiratory distress syndrome. Standard clinical and radiographic criteria were used to diagnose respiratory distress syndrome, and the diagnosis was confirmed by reviewing newborn records. Twenty (25%) infants delivered within 24 hours of sample collection developed RDS. Lamellar body count more than 50,000/microl predicted pulmonary maturity. Seventeen out of 20 respiratory distress syndrome cases had been predicted correctly. The negative predictive value of lamellar body count>50,000/microl was 93% and positive predictive value was 48% and the sensitivity for prediction of RDS was 85% and specificity was 70%. Lamellar body count can be used as a favourable predictor of fetal lung maturity because it is quick, simple and universally available. Also it can be used as an extremely inexpensive, reliable screening test for evaluating fetal lung maturity.

Abstract
The results are presented of tests conducted at three different depths of cut and a velocity of 3.1 m/min on a work-hardening lead-alloy workpiece with a 10-degree-rake photoelastic tool. In addition to examining the behaviour of the chip-tool contact stresses, the paper considers the forces acting on the tool and distinguishes three areas: rake, nose, and flank. It evaluates the rake forces from the photoelastic results directly, estimates the nose forces by making certain assumptions with regard to the distribution of stresses, and neglects the stresses on the flank. The sum of the forces so obtained is then compared with the measured resultant cutting force; there is good agreement. There is a particularly significant observation which, contrary to previously published results, shows that the frictional stresses vary linearly in the so-called sticking zone and tend towards a constant only at relatively high depths of cut. This is discussed in relation to the general concept of plastic friction and the variation of the coefficient of friction on the rake face. The significance of the measured resultant coefficient of friction is also considered.
