maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. the majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. conventional radiographs could not differentiate between infl ammatory mucosal thickening, neoplasm, and hypoplasia of t...

PRIMARY STUDY OBJECTIVE To determine the appropriate role and timing of sinus imaging studies in the evaluation and treatment of chronic cough. DESIGN Prospective study of chronic cough. All patients underwent sinus imaging, the results of which identified prospectively the following: (1) fluid in sinuses, with or without opacification, and (2) mucosal thickening. Patients then were treated u...

albright syndrome is a rare condition, usually appears in the early years of life and characterized by bending or thickening of long bones. in girls, of endocrine glands disorders especially precocious puberty are the most common symptoms. also, brown pigments in the skin are another sing of this syndrome. certain mucosal and skin pigments are considerable features of the disease. etiology and ...

Introdouction: Cone Beam Computed Tomography (CBCT) is a relatively new three-dimensional imaging technology, which has been widely used in dental and maxillofacial imaging. Materials and methods: CBCT scans of 506 maxillary sinuses of 253 individuals (39.9% male and 60.1% female) were evaluated retrospectively for assessing the relationship between sinus mucosal thickening (MT) and dental a...

Biomass is widely used for fuel in developing countries. Particles and gases of biomass burning may cause changes in the lung. In this prospective study we investigated histopathological changes in the lungs of 42 non-smoking women [mean age (59±10) years] caused by biomass smoke. We valuated exposure to biomass smoke, case histories, and the findings of physical examination, radiology, broncho...

AIM To clarify the endoscopic mucosal change of the stomach caused by Lugol's iodine solution spray on screening esophagogastroduodenoscopy (EGD). METHODS Sixty-four consecutive patients who underwent EGD for esophageal squamous cell carcinoma screening were included in this study. The records for these patients included gastric mucosa findings before and after Lugol's iodine solution was spr...

Ultraviolet B (UVB; 290~320nm) irradiation-induced lipid peroxidation induces inflammatory responses that lead to skin wrinkle formation and epidermal thickening. Peroxisome proliferator-activated receptor (PPAR) α/γ dual agonists have the potential to be used as anti-wrinkle agents because they inhibit inflammatory response and lipid peroxidation. In this study, we evaluated the function of 2-...

background: maxillary sinuses are covered by a 1 mm thick mucous membrane that when this membrane becomes infl amed, the thickness may increase 10-15 times. the common causes of odontogenic sinusitis are dental abscesses and periodontal disease. computed tomography (ct) is considered the gold standard for sinus diagnosis. recently, cone beam computed tomography (cbct) has been introduced for de...

OBJECTIVES/HYPOTHESIS To evaluate the efficacy of canine fossa puncture (CFP) by comparing patients with unilateral chronic rhinosinusitis (CRS) accompanying nasal polyposis (NP) who underwent CFP with those who underwent maxillary sinus clearance through a middle meatal antrostomy (MMA). STUDY DESIGN Prospective randomized study. METHODS Twenty-nine patients were randomly assigned to the C...
