Aural Myiasis in Children and Literature Review
(Tohoku Univ Medical Press, 2005) Yuca, K; Çaksen, H; Sakin, YF; Yuca, SA; Kiris, M; Yilmaz, H; Çankaya, H
Myiasis is a disease caused by fly larvae. The term "myiasis" is derived from the Greek word "myia" meaning fly. Aural myiasis is a rare clinical state and occurs frequently in children. In this article, six children with aural myiasis, caused by the fly larvae, are reported because of unusual presentation. All of the children with aural myiasis were associated with chronic otitis media. In the treatment, a combination of suctioning and alligator forceps was used to remove maggots under the light microscopic field. Additionally, antibiotics were used in all children. Thus, aural myiasis is successfully treated by direct extraction of larvae and application of preventative methods. - myiasis; fly larvae; chronic otitis media; maggots; children (c) 2005 Tohoku University Medical Press.

Hemangioma With Phleboliths in the Sublingual Gland
(Tohoku Univ Medical Press, 2003) Çankaya, H; Ünal, Ö; Ugras, S; Yuca, K; Kiris, M
Hemangiomas are the most common lesions of the major salivary glands during infancy and early childhood. Changes in blood flow dynamic within hemangioma results in thrombus and phleboliths. There have been a number of reports of hemangiomas with phleboliths in parotid and submandibular glands. We present the first case of a hemangioma with multiple phleboliths in the subligual gland as a cause of submental opacity, and discussed the diagnosis of radiopaque masses in the sublingual and submental regions.

The Importance of Rigid Nasal Endoscopy in the Diagnosis and Treatment of Rhinolithiasis
(Elsevier Sci Ltd, 2006) Yuca, K; Çaksen, H; Etlik, Ö; Bayram, I; Sakin, YF; Dülger, H; Kiris, M
Objectives: Rhinolithiasis is the presence of mineralized and calcareous formations located in the nasal cavity. They have rare occurrence and can be easily confused with infection or obstruction of tipper airways. If they are undetected for a long time, they may grow large enough to cause of nasal obstruction, mimicking sinusitis. Seven cases of rhinolithiasis were presented, and their diagnosis was made by rigid endoscopic nasal examination. Also computerized tomography scan was used to describe the size and site of the rhinoliths accurately. Our purpose was to determine the role of rigid nasal endoscopy in the diagnosis and the treatment of rhinolithiasis. Methods: In this study, seven cases of rhinolithiasis, who were diagnosed and treated by rigid nasal endoscopy were presented. Results: Between January 2000 and November 2004, seven cases (Four males and three females: age ranged front 8 to 45 years) with rhinolithiasis were diagnosed. The most frequent symptoms were nasal obstruction With purulent rhinorhea. nasal and oral malodor. As complementary examinations, computerized tomography and simple X-ray of paranasal sinuses were used to locate and measure the dimension of calcareous mass, and to reveal possible invasion of the adjacent structures. The removal of rhinolithiasis was done with rigid nasal endoscopy under topical anesthesia in six cases and general anesthesia in one case. Conclusion: Rhinolithiasis is a rare condition but must always be suspected in patients with long standing nasal obstruction, nasal and oral malodor, purulent rhinorrhea and chronic headache.

Local Irritant Effects of Topical Oral Sprays on Oral Mucosa in Mice
(Springer, 2006) Yuca, K; Çankaya, H; Bayram, W; Özbek, H; Kiris, M
Topical oral sprays are frequently used to prevent and manage oropharyngeal inflammation and lesions. This study investigated the histopathologic changes noted in the oral mucosa of mice after topical application of 3 widely prescribed antibacterial products. The 25 animals were divided into 5 groups and treated for 10 days with 2 sprays daily, as follows: group 1 - chlorhexidine gluconate 0.12% * benzydamine hydrochloride 0.15%; group 2 - benzydamine 0.27 mg/0.18 mL * 30 mL; group 3 - chlorhexidine 0.2%; group 4 - fusafungine 1%; and group 5 (cohort) - physiologic serum. On day 10 after drug administration, biopsy specimens were taken from the oropharyngeal mucosa of the tongue, the cheek mucosa, and the tongue base; these were examined under a light microscope and were classified as normal or pathologic. All topical oral sprays produced some degree of histopathologic change, such as hyperplasia, fibrosis, low-grade dysplasia, congestion, or edema. The local irritant effects of topical oral sprays should be considered when treatment is selected for patients with oropharyngeal disorder.
Nasal Obstruction as a Common Side-Effect of Sildenafil Citrate
(Tohoku Univ Medical Press, 2006) Kiroglu, AF; Bayrakli, H; Yuca, K; Cankaya, H; Kiris, M
Sildenafil citrate is an effective oral drug for erectile dysfunction. The main action of sildenafil is the enhancement of the effect of nitric oxide (NO) by inhibiting the cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase-5 (PDE-5). an enzyme responsible for degradation of cGMP. NO is also present in the nasal mucosa and is responsible for vasodilation causing congestion and nasal obstruction. The aim of this study was to detect the effect of sildenafil on nasal mucosa in terms of nasal obstruction. A total of 16 patients presented to urology clinic suffering from impotence and medicated with sildenafil were included in the study. Before and after oral administration of 50 mg sildenafil, in all of the patients the nasal patency was examined by active anterior rhinomanometry (a method of assessing nasal resistance) using air pressure of 150 Pascal. In addition, all patients were asked about their sensation of nasal patency to detect the symptomatic nasal obstruction. There was a significant decrease in nasal air flow values (cm(3)/s) (p < 0.05). Except for three cases, all patients indicated that they had the sensation of nasal obstruction after the use of sildenafil (p < 0.05). Nasal obstruction is a common complaint for the patients using Sildenafil.
Oxidant and Antioxidant Levels in Children With Acute Otitis Media and Tonsillitis
(Elsevier Ireland Ltd, 2005) Cemek, M; Dede, S; Bayiroglu, F; Çaksen, H; Cemek, F; Yuca, K
Objective: Recurrent episodes of acute otitis media (AOM) and acute tonsillitis (AT) are a common problem in infectious disorders during childhood and are major cause of morbidity in children. The organism maintains defense systems including nonenzymatic antioxidants such as Vitamins A, E and C and reduced glutathione (GSH) against reactive oxygen species (ROS). In the present study, Lipid peroxidation status and nonenzymatic antioxidant capacity were investigated in children with AOM and AT. Our aim was to compare the lipid peroxidation and responses of the body's antioxidant status in the closely associated infections such as AOM and acute tonsillitis. Methods: The study included 23 (14 mates, 9 females) children with AOM, 27 (14 mates, 13 females) with AT and 29 (16 mates, 13 females) healthy control subjects. The ages of the study and control subjects were between 2 and 7 years. Serum beta-carotene, retinol, Vitamin E, Vitamin C, and whole blood malondialdehyde (MDA) (as an indicator of lipid peroxidation) and GSH Levels were studied in all subjects. Results: There was a statistically significant difference between the groups for all parameters (P < 0.05). All of the antioxidant vitamins such as beta-carotene, retinol, Vitamin E, and Vitamin C levels were observed to be significantly decreased in the both patient groups. Nevertheless, GSH levels were also decreased in the patient groups. MDA levels were found to be higher in children with AOM and AT than in the healthy control subjects. When compared the AOM and AT groups, there was statistically significant difference between the groups for whole blood MDA (P < 0.05). Conclusion: Even though they seem to react in a similar way against ROS, in the cases of AOM and AT, it is possible to see the different approaches in these tissues for the oxidative stress.

Papillary Thyroid Carcinoma Presenting as a Giant Cervical Mass
(Royal Belgian Society Ear, Nose, Throat, Head & Neck Surgery, 2005) Yuca, K; Ünal, Ö; Bayram, I; Çankaya, H; Kiris, M
Papillary thyroid carcinoma presenting as a giant cervical mass; a case report. Papillary thyroid carcinoma (PTC) is a relatively uncommon malignancy. The prognosis is generally good and the mortality rate is low. PTC is more common in younger patients; incidence is two to three times higher in women and in individuals with radiation exposure to the neck. We report on a 75-year-old woman with PTC admitted to our clinic for a giant mass in the neck dating back ten years. A hyperintense huge cystic lesion and hypo-intense central solid component were seen on T1- and T2-weighted magnetic resonance imaging. No distant metastasis was present. The PTC was treated surgically and radioiodine (I-131) treatment was applied postoperatively. No recurrence was observed one year later.
Pediatric Intraoral Ranulas
(Tohoku Univ Medical Press, 2005) Yuca, K; Bayram, I; Çankaya, H; Çaksen, H; Kiroglu, AF; Kiris, M
An intraoral ranula is a retention cyst arises from the sublingual gland on the floor of the mouth as a result of ductal obstruction and fluid retention. Many techniques for management of ranulas have been described in the literature. The purpose of this study was to analyze our surgically treated pediatric patients with Intraoral ranulas and to discuss the results in the light of the literature. Nine pediatric patients (six females and three males) with intraoral ranulas surgically treated were analyzed retrospectively regarding their treatment methods and results. The surgical specimens were also re-examined histologically. Seven cases of superficial, protruded and smaller than 2 cm ranulas were treated with marsupialization (unroofing). Two cases who were previously operated and then recurred had bigger than 2 cm ranulas. In these two cases. marsupialization of the ranula plus removal of the sublingual gland was performed. The most common complication was intraoperative cyst rupture of the ranula, which was noted in four cases. A recurrence was observed in only one case in the 16th months of follow up period. Our findings show that marsupialization is a suitable and effective method for pediatric intraoral ranulas, whereas in recurrent cases marsupialization of the ranula combined with total excision of sublingual gland may be preferred - ranula: intraoral cyst; sublingual mass, inarsupialization (C) 2005 Tohoku University Medical Press
Report of an Infant With Noma (Cancrum Oris)
(Japanese dermatolgical Assoc, 2004) Yuca, K; Yuca, SA; Cankaya, H; Çaksen, H; Çalka, M; Kiris, M
Noma (cancrum oris) is an infectious disease that destroys the oro-facial tissues and other neighboring structures in its fulminating course. The starting point of the disease is acute ulcero-necrotic gingivitis, which results in an extensive gangrenous plaque destroying all of the soft tissues of the face. It predominantly affects children aged 2-16 years and is primarily seen in areas where the socioeconomic standards are low and there is poor hygiene, as in developing countries. We discuss possible predisposing factors in cancrum oris such as malnutrition, infectious diseases, HIV infection, and immune compromise conditions. Poverty is the most important risk factor. We report the case of a 6-month-old child with noma and review the characteristic features of this disease.
