Acute invasive fungal rhinosinusitis: Molecular identification and update in management of frozen section biopsy.

The clinical diagnosis of Acute Invasive Fungal Rhinosinusitis (AIFRS) is technically difficult because it presents with non-exclusive and nonspecific clinical symptoms. Laboratory confirmation (usually via histopathologic techniques such as formalin-fixed paraffin-embedded (FFPE)) is necessary but it is time-consuming, despite the urgent need for timely diagnosis of AIFRS for effective management. This study aimed to investigate the sensitivity and specificity of the GMS frozen-section biopsy in the diagnosis of AIFRS and compare the same with that of different tissue staining methods to provide valid decision-grounds that may guide clinicians in prompt diagnosis of acute fungal invasive rhinosinusitis.

Effect of ESS on Olfactory Threshold of Patients with CRS without Nasal Polyps.

Objectives: Chronic rhinosinusitis (CRS) is characterized by a long-time inflammatory disease of nasal and sinus mucosa. Olfactory dysfunction is common among CRS patients with a prevalence ranging from 48% to 83%. We aimed to assess the effect of ESS on olfactory function of patients with chronic rhinosinusitis without nasal polyps.

Reliability of fine-needle aspiration and ultrasound-based characteristics of thyroid nodules for diagnosing malignancy in Iranian patients.

Background: Sonography and fine-needle aspiration biopsy (FNA-B) have been approved as method of choice in diagnosis of malignant thyroid nodules. Unnecessary FNA-B not only is invasive and costly but also results in second biopsy or unnecessary surgery. So we aimed to determine the specificity and sensitivity of sonography and FNA-B, without sonography guidance, in diagnosis of malignant and benign thyroid nodules.

Comparing the effects of ketotifen fumarate eye drops and ketotifen oral pills on symptom severity and quality of life in patients with allergic rhinitis: a double-blind randomized clinical trial.

Background: Allergic rhinitis is a chronic inflammatory disease of nasal mucosa. Previous studies have shown the therapeutic effects of ketotifen eye drops on allergic conjunctivitis and rhinitis patients. This study was designed to compare the effects of ketotifen drops and oral ketotifen pills on symptoms and quality of life in allergic rhinitis patients.

Investigation of the effectiveness of Syzygium aromaticum, Lavandula angustifolia and Geranium robertianum essential oils in the treatment of acute external otitis: a comparative trial with ciprofloxacin.

Background: Antibiotics and anti-inflammatory agents are the mainstay of acute external otitis (AEO) treatment. The present study investigated the effectiveness of a combination herbal drop (Lamigex) composed of essential oils from Syzygium aromaticum, Lavandula angustifolia, and Geranium robertianum in the alleviation of AEO symptoms and compared its effects to those of ciprofloxacin 0.3% drop.

Late laryngeal findings in sulfur mustard poisoning.

Introduction: Sulfur mustard is an alkylating warfare agent and its inhalation results in early and late toxic effects. This agent was used widely against both military and civilian population by Iraqi forces in the Iran-Iraq war (1983-88). The purpose of the study was to describe abnormal laryngeal findings in a group of chemical war injury patients (soldiers) 20 years after an acute exposure to sulfur mustard.
