Öğe [Acinetobacter baumannii: a rare cause of deep neck infection](2012) Kınış V.; Bakır S.; Ozbay M.; Yorgancılar E.; Topçu I.; Tekin A.[No abstract available]Öğe Auricular mucormycosis: a case report.(2007) Oktay M.F.; Askar I.; Kilinç N.; Tuzcu A.; Topçu I.Mucormycosis is a rare, saprophytic, invasive, and fulminant fungal disease. It occurs in immunocompromised patients such as those with diabetes mellitus or blood dyscrasia, or in patients under immunosuppressive therapy. A 17-year-old female patient with diabetic ketoacidosis presented with a black-colored lesion in the auricle and external ear canal. Physical examination showed necrosis of the auricle, external ear canal, and neighboring skin. She also had facial paralysis. Debridement of the necrotic tissues was performed and the samples were submitted for microbiologic and histopathologic examination, which showed nonseptate hyphae. Postoperatively, systemic amphotericin B was empirically administered. The patient died on the seventh day.Öğe A case of solitary angiokeratoma circumscriptum of the tongue.(2007) Yildirim M.; Kilinç N.; Oktay M.F.; Topçu I.Angiokeratoma circumscriptum is an uncommon vascular entity. The lesion is present at birth and usually involves the lower extremities. A 9-year-old girl presented with multiple pink-colored, small-raised lesions in the dorsal part of her tongue, which had been present since birth. There was no history of trauma, cold injury, or similar lesions elsewhere in her body. She complained of pain and rare bleeding from the lesions after eating hard foods. Physical examination showed multiple, grouped, erythematous, shiny papules mostly in the dorsal aspect of the tongue. There were no other lesions in other parts of the oral mucosa. After an incisional biopsy of the lesion, the diagnosis was made as solitary angiokeratoma circumscriptum.Öğe Clinical assessment of patients with chronic otitis media with cholesteatoma(2002) Tekin M.; Osma U.; Meriç F.; Topçu I.OBJECTIVES: We evaluated clinical features and treatment results of patients with chronic otitis media (COM) with cholesteatoma. PATIENTS AND METHODS: The study included 83 patients (53 males, 30 females; mean age 27.5 years; range 7 to 60 years) who were treated for COM with cholesteatoma. All patients underwent otoscopic examination, audiometric investigation, temporal bone computed tomography, and when necessary, cranial tomography. Open or closed mastoidectomy was performed depending on the extent of cholesteatoma and perioperative appearance of the ear. RESULTS: Open- and closed-technique mastoidectomies were performed in 64 and 19 patients, respectively. Ossicular chain defects were observed in 90.3% of patients, and 9.7% had no detectable ossicular chain. Cranial complications were present in 28%. Of patients who had undergone open mastoidectomy, 75% had dry ears, 11% had recurrent ear discharge, and 14% required revision mastoidectomy because of recurrence. Of those who had been treated by closed-technique, 79% had dry ears, whereas 21% required revision mastoidectomy. Recurrent cholesteatoma was detected in 85% of patients during revision mastoidectomy. CONCLUSION: We prefer open-technique mastoidectomy in chronic otitis media patients with extensive cholesteatoma, bone destruction, and hearing impairment. This choice mainly relies on the socioeconomic status of patients and difficulty in having patient compliance with follow-up controls.Öğe Double thyroglossal duct cyst located in the hyoid region and the tongue base: an unusual coexistence.(2011) Yorgancilar E.; Yildirim M.; Gün R.; Büyükbayram H.; Topçu I.Thyroglossal duct cysts originate from persistent epithelial remnants of the thyroglossal duct that are present during the descent of the thyroid gland from the foramen cecum to its final position in the anterior neck. Thyroglossal duct may persist anywhere along the descent from the tongue to the thyroid. Lingually localized thyroglossal duct cysts are congenital lesions of the pharynx, which are very uncommon and may cause morbidity and mortality if not treated expeditiously. Double thyroglossal cysts and the complete failure of the obliterative process of thyroglossal duct are very rare in the literature. In this article, we describe a case of two cysts derived from the same thyroglossal duct, one in the hyoid region and the other in the tongue base. To our knowledge, this coexistence has not been described previously in the literature.Öğe Evaluation of brainstem auditory evoked responses in patients with conversion disorders(2000) Cüreoğlu S.; Altindağ A.; Osma Ü.; Özen Ş.; Oktay F.; Meriç F.; Topçu I.Objective: The aim of this study was to detect any suboptimal brainstem lesions in patients with conversion disorder. Methods: This study included 37 patients (25 female, 12 male) with conversion disorder. Control's group included 30 healthy persons (22 female, 8 male). The diagnosis of conversion disorder was based on criteria of DSM IV. BAER was recorded at conventional and higher stimulus rate in these patients. The main BAER measurements analyzed were the I-III, III-V, and I-V interpeak intervals and the wave V amplitude. Results: There was significant difference for I-III (p<0,05), I-V (p<0,05) interpeak latencies between patient and controls groups at 10/s click rate. The only I-III interval differed significantly at 50/s click rate. Abnormal BAER result was seen in only one of 37 patients at the clicks of 10/s and 50/s, when the values exceeding 2.5 standard deviations above the means of the normal controls were considered abnormal. No significant correlation was found between diseased period and BAER latencies. Conclusion: The lower brainstem (cochlear nucleus, superior olivary complex and lateral lemniscus) has been affected in patients with conversion disorder.Öğe External auditory canal osteoma resulting in cholesteatoma which is complicated with meningitis(2013) Yorgancılar E.; Kınış V.; Gün R.; Bakır S.; Ozbay M.; Topçu I.[No abstract available]Öğe Preventing cisplatin induced ototoxicity by N-acetylcysteine and salicylate.(2010) Yildirim M.; Inançli H.M.; Samanci B.; Oktay M.F.; Enöz M.; Topçu I.In this study we investigated if CP induced ototoxicity could be prevented or reduced by the use of salicylate and N-acetylcysteine. Fifty-four patients (28 females, 26 males; mean age 37+/-9.5 years; range 29 to 71 years) who had cisplatin chemotherapy due to solid organ tumors were enrolled in the study. The patients were randomized into three groups, with 18 patients in each group. The first group (control group) received cisplatin, second group received N-acetylcysteine (NAC; 600 mg/day) with cisplatin and the third group received salicylate (300 mg/day) with cisplatin. All patients evaluated audiologically including high frequency audiometry and auditory brainstem response. The cisplatin-induced ototoxic damage could be reduced in 10,000 and 12,000 Hz frequencies when N-acetylcysteine was added to the cisplatin therapy protocol. There was no decrease in the hearing loss levels of the patients who were receiving cisplatin with salicylate. According to auditory brainstem response testing results, there was no difference detected between N-acetylcysteine or salicylate for the amelioration of cisplatin induced ototoxicity.Öğe Tuberculous parotitis: a review of seven cases.(2007) Oktay M.F.; Aşkar I.; Yildirim M.; Topçu I.; Meriç F.OBJECTIVES: Tuberculous parotitis is rare even in countries where tuberculosis is widespread. We evaluated seven patients with tuberculous parotitis together with clinical and histopathologic findings, and management. PATIENTS AND METHODS: In a period of 13 years, seven patients (5 males, 2 females; mean age 32 years; range 23 to 47 years) were diagnosed and treated for tuberculous parotitis. All the patients had a clinical suspicion of a parotid gland tumor. RESULTS: The lesions were localized on the left in four patients, and on the right in three patients. The duration of disease varied from seven months to three years. The masses were localized, mobile, and measured 3 to 6 cm in diameter; one was fistulized. There was no evidence for active pulmonary tuberculosis. Chest radiograms showed old tuberculous lesions in two patients. The PPD skin test results were positive (>12 mm induration) in five patients (71%). Computed tomography or magnetic resonance imaging obtained in five patients showed mass formation suggesting a benign parotid gland tumor. Fine-needle aspiration cytology performed in three patients and cultivation performed in the fistulized case were all non-diagnostic. Superficial parotidectomy was performed in six patients and enucleation was performed in one patient. Histopathologic examination showed tubercles composed of macrophages, epithelioid cells and Langhans giant cells, and central caseous necrosis. Following diagnosis, all patients were treated with a four-drug chemotherapy regimen. There was no evidence for recurrence within a mean of 15-month follow-up. CONCLUSION: Tuberculosis of the parotid gland should be considered in the differential diagnosis of patients presenting with a solitary tumor in the parotid gland.
