Epidemiological Study of Head and Neck Sarcomas.

Introduction: Head and neck sarcomas are uncommon tumors that account for less than 1% of head and neck malignancies and fewer than 5% of all sarcomas. This study aims to assess the head and neck sarcomas pattern in Isfahan, Iran, compare its results with previous findings, and investigate treatment methods and the recurrence and survival rate.

Materials And Methods: This study was done on 160 patients diagnosed with head and neck sarcomas between 2001 and 2020 in four medical centers in Isfahan, Iran.

Limited Approach in Endoscopic Dacryocystorhinostomy of Pediatrics.

Background: Limited spatial nasal cavity in children, make pediatric dacryocystorhinostomy (DCR) a difficult surgical procedure. We apply a limited approach to pediatric DCR and follow them for their consequences.

Materials And Methods: An experimental study was done in pediatric DCR with limited approach (age < 14-year-old).

A Rare Case of Aneurysmal Bone Cyst in the Paranasal Sinus.

Introduction: Aneurysmal Bone cysts (ABC) are extremely rare in the head and neck region and even rarer in sinuses. ABC is a benign multicystic mass that is locally-destructive and rapidly expandable. Hemorrhagic fluid content (like in this case) and septated appearance are the characteristic feature of ABC.

Applied Endoscopic Anatomical Evaluation of the Lacrimal Sac.

Introduction: Dacryocystorhinostomy (DCR), a popular surgical procedure, has been performed using an endoscopic approach over recent years. Excellent anatomical knowledge is required for this endoscopic surgical approach. This study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the Isfahan forensic center as a sample of the Iranian population.

The role of folic acid on the hyperhomocysteinemia in the Buerger's disease (Thromboangiitis Obliterans).

Background: The mechanism underlying Buerger's disease (BD) is still unknown. Recently, thrombophilic conditions predisposing to a hypercoagulable state have been hypothesized as triggers for BD. The aim of the study is to evaluate the prevalence of the hyperhomocysteinemia and level of the anticardiolipin antibodies, and the role of folic acid on the hyperhomocysteinemia and on the rate of the amputations in the patients with BD.

Lipoma of paraglottic space in a child: a case report.

Introduction: Lipomas of the larynx are very rare benign lesions; macroscopically, they resemble retention cysts, so their diagnosis is usually made after surgery.

Case Report: A rare case of pediatric paraglottic space Lipoma in an 11-year-old boy is explained. The mass was mobile, soft, without fluctuation or pulsation.

Comparison of tympanic membrane grafting medial or lateral to malleus handle.

Background: To compare two methods of tympanic membrane (TM) grafting when graft materials medial or lateral to malleus, this study have been done.

Materials And Methods: In this clinical trial which was conducted in Alzahra and Kashani hospitals, between June 2010 and February 2012, 56 patients with chronic otitis media and perforated TM entered the study in two groups. The inclusion criteria consisted of patients who were at least 15-years-old without history of smoking, diabetes mellitus or autoimmune disease.

Supraglottic paraganglioma originated from superior laryngeal nerve.

Neurogenic tumors, especially paraganglioma of larynx, are rare. In this article, we present a 64-year-old woman who complained of intermittent dysphagia to solid foods. Further evaluation revealed a supraglottic paraganglioma and she was treated successfully by total excision of tumor.

Comparison of Preoperative Temporal Bone CT with Intraoperative Findings in Patients with Cholesteatoma.

Introduction: Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. The necessity for imaging in an uncomplicated case is controversial. This study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (HRCT) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the correspondence between pre- and intraoperative CT findings in patients with cholesteatoma.

The comparison of the complications of axillobrachial and femorofemoral arteriovenous shunt prostheses in hemodialysis, a 3 year study in Alzahra general hospital.

Background: This study was performed to compare the outcome and complications of axillobrachial and femorofemoral graft as upper and lower limb arteriovenous shunt prostheses.

Materials And Methods: In a prospective cohort study, we observed and followed-up all cases with a new insertion of ePTFE between February 2006 and February 2009. Assessment of patency and the complication rates of their prostheses were the essential parts of this observation.

Wegener's granulomatosis and mucoromycosis: A case study and review of literature.

Mucormycosis is a fatal invasive infection which mostly involves diabetic or immunosuppressed patients. Early diagnosis, improving immunosuppression, systemic antifungal therapy, and surgical debridement are necessary for successful treatment. In this case study, we represent a known case of Wegener's granulomatosis (WG), with concomitant sinusal mucormycosis mimicking vasculitic disease relapse, which was successfully treated with surgical debridement, amphotericine, and intravenous immunoglobuline.

Otorrhagia bleeding due to leech bite.

Leeches are blood-sucking hermaphroditic parasites that attach to vertebrate hosts, bite through the skin, and suck out blood. When leeches feed, they secrete an anticoagulant (hirudin), which helps them get a full meal of blood. This is the first report of leech removal from external auditory canal.

Comparison of impulse osillometry system and spirometry for diagnosis of obstructive lung disorders.

Background: Obstructive lung disease is a growing health problem, especially in developed countries. This study aimed to compare Impulse Osillometry System (IOS) and Spirometry for evaluation of Chronic Obstructive Pulmonary Disease and asthma.

Materials And Methods: The study groups contained 87 healthy people, 87 asthmatic patients and 56 COPD patients.

Influence of intralumenal and antibiotic-lock of vancomycin on the rate of catheter removal in the patients with permanent hemodialysis catheters.

Infection of permanent catheters (Permcath) in hemodialysis (HD) patients can lead to catheter removal. The successful use of an antibiotic-lock to treat infection has reported good results in the treatment of catheters' infections. This study was designed to evaluate the impact of the intraluminal vancomycin in comparison with intravenous antibiotic administration.

Spironolactone in chronic hemodialysis patients improves cardiac function.

We performed this study to assess whether low dose spironolactone could be administered in hemodialysis (HD) patients with moderate to severe heart failure to improve cardiovascular function and reduce hospitalization without inducing hyperkalemia. We enrolled 16 chronic HD patients with moderate to severe heart failure and left ventricle ejection fraction :5 45%. In a double blinded randomized placebo controlled study, one group of 8 patients received 25 mg of spironolactone after each dialysis session within six months, and the rest received a placebo.
