Introduction: Multifocal Langerhans' cell histocytosis is a rare condition that can affect multiple organs and manifest in various scenarios. While the condition is more commonly found in children, it can also occur in adults.

Case Report: A 43-year-old female presented with refractory otorrhea and had a rubbery neck mass in the left mid-cervical area, as well as an itchy eczematoid lesion in the left parietal area.

Effect of fluoxetine on seizures in rats with high susceptibility to audiogenic stress.

Background: The seizures, triggered by a loud sound in laboratory animals, are associated with the imbalance of the brain monoamines. Serotonin (5-HT) is regarded as one of the principal neurotransmitters to be involved in regulation of wide variety of physiological and psychological processes. Among the drugs that affect 5-HT synaptic transmission, the leading role is given to selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine.

Effect of Functional Endoscopic Sinus Surgery on the Voice Quality among Patients with Rhinosinus Polyposis.

Introduction: Rhinosinus polyposis is associated with voice quality reduction. There has been little evidence about the efficacy of rhinosinus polyps surgery on patients' voice quality so far. The aim of the present study was to evaluate the nasality and acoustic voice changes after rhinosinus polyposis surgery.

Sleep quality after endoscopic sinus surgery in patients with sinonasal polyposis.

Objectives: Evaluate the effect of functional endoscopic sinus surgery (FESS) for nasal polyposis on sleep efficiency and polysomnographic parameters.

Subjects And Methods: This clinical trial was conducted on 15 patients with bilateral massive sinonasal polyposis who underwent FESS between August 2012 and September 2013. All participants were evaluated subjectively by employing the Pittsburgh Sleep Quality Index (PSQI) questionnaire and objectively (provided by polysomnographic parameters) before and 2 months after surgery.

Long-Term Survival of Cutaneous Malignant Melanoma with Metastasis to Paranasal Sinuses: A Case Report and Literature Review.

Background: Malignant melanoma (MM) usually present with metastases to unexpected regions of the body. Metastatic MM is a highly lethal condition, and the median survival in this setting is 6 to 7.5 months; however, few reports rarely describe long-term after chemotherapy.

Acute invasive fungal rhinosinusitis: our experience with 18 cases.

Acute invasive fungal rhinosinusitis (AIFRS) is a rapidly progressive life threatening infection that is seen most commonly among immunocompromised patients. We present a case series of 18 patients clinically and histopathologically diagnosed with AIFRS with a mean follow-up of 9.11 ± 2.

Facial soft-tissue morphology of adolescent patients with nonsyndromic bilateral cleft lip and palate.

The purpose of this study was to cephalometrically evaluate the facial soft-tissue characteristics of adolescent patients with bilateral cleft lip and palate (BCLP) and to compare them with a noncleft control group. Lateral cephalometric radiographs obtained from 56 adolescents with nonsyndromic BCLP (29 boys and 27 girls) were analyzed and compared with 67 control subjects (29 boys and 38 girls) who were matched for sex, age, and ethnicity. All patients had been operated on before the age of 2 years for the surgical repair of cleft lip and palate.

Nodular fasciitis of the auricle: a case report.

Introduction: Nodular fasciitis is described as a benign reactive proliferation of myofibroblasts. Due to its rapid-growing nature, a precise clinical diagnosis is difficult and the condition is frequently misdiagnosed as malignant lesions.

Case Report: In this study, we present the case of a young woman with an auricular nodular fasciitis as an example of one of the rarest sites of this tumor.

Postoperative histological changes in polypose rhinosinusitis.

The aim of this study was to evaluate the effect of surgery on the histology of nasal mucosa in patients with nasal polyposis and the comparison/also to compare it with normal population. This case-control study was conducted on 20 patients at the Otorhinolaryngology-Head and Neck Surgery Department, Qaem Hospital, Mashhad University of Medical Sciences during October 2007 to June 2008. Patients with polyposis and patients with septal deviation who were candidate for septoplasty were considered as case and control groups, respectively, including 10 subjects in each.

Prevalence of dental anomalies in patients with cleft lip and palate.

The aim of the present study was to investigate the prevalence of dental anomalies in a group of patients with cleft lip and palate (CL/P) in the northeast of Iran. Ninety-one patients referring to the Cleft Lip and Palate Clinic of Mashhad Dental School were enrolled and classified into right CL/P, left CL/P, and bilateral CL/P groups. Photographs, dental casts, and panoramic and periapical radiographs were retrieved, and dental anomalies were recorded.

Oral health-related quality of life in children with cleft lip and palate.

Considering the essential need for oral health-related quality-of-life measures for patients with craniofacial malformations, the current study aimed to investigate the oral health-related quality of life of Iranian patients with cleft lip and palate. Fifty children referred to Cleft lip/Palate Research Center of Mashhad Dental School (Iran) were recruited. Participants were asked to complete the Child Oral Health Impact Profile questionnaire.

The prevalence of allergic fungal rhinosinusitis in sinonasal polyposis.

Allergic fungal sinusitis (AFS) is a noninvasive form of fungal rhinosinusitis with a prevalence of 6-9 % among all rhinosinusitis cases requiring surgery. The fungi causing AFRS have a great diversity and regional variation in the incidence of AFS has been reported worldwide. The aim of this study was to evaluate the prevalence of AFS among rhinosinusitis patients in the north east of Iran.

Lobular capillary hemangioma of middle turbinate literature survey and case report.

Introduction: Lobular capillary hemangioma (LCH) is a benign lesion of vascular origin. It rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis.

Case Report: In this report we present a case of LCH of the nasal cavity which occurred approximately one month after delivery.

The right of all nations to access science, new technologies and sustainable development.

This article explores the need for reflection on the right of developing countries to science and technology in addition to explaining the place of the scientific rights of nations in human rights as a whole. The discussion was conducted in relation to sustainable development. Through the examination of the current situation and the challenges to sustainable development, and taking into account the imbalance in the distribution of the benefits of science and new technologies, the authors advocate a comprehensive approach to promote cooperation and capacity-building in this area.
