Role of uric acid and other parameters in sudden sensorineural hearing loss

Aim: To investigate the levels of metabolites (predominantly uric acid) effective on biochemical, and coagulation parameters and evaluate their effects on the onset, and course of the disease. Methods: In this retrospective study, files of 92 patients hospitalized between January 2007, and December 2013, in our clinic with established diagnosis of sudden hearing loss were screened. The biochemical (predominantly uric acid), and hematological parameters were compared with those of the control group. In addition, the patient group was divided into two groups according to uric acid levels and the difference between the groups was investigated in terms of the onset or course of the disease. Results: A significant difference was not detected between the patient, and the control groups regarding mean uric acid levels. Among biochemical parameters glucose, creatinine, and international normalized ratio (INR) were significantly higher (p<0.05) while a significant intergroup difference was not detected as for other parameters. A significant intergroup difference was not detected in mean pure- tone averages, and mean hearing gain at admission between two groups formed based on uric acid levels, while post-treatment pure-tone average was significantly better in patients with higher serum uric acid levels. In the patient group, uric acid levels were significantly higher in patients with partial hearing loss relative to those with total loss. Conclusion: In our study, we could not find a significant difference between the patient and the control groups as for uric acid levels. However, we have encountered evidence supporting the possible role of serum uric acid levels in the prognosis of sudden hearing loss

Mullerian inhibiting substance expression in papillary thyroid cancer

SummaryObjectiveTo examine the expression of Mullerian inhibiting substance (MIS) in papillary thyroid cancer.Materials and methodsThe MIS expression was examined by studying the immunohistochemistry in deparafinized sections prepared from tissue blocks of patients who were diagnosed with papillary thyroid cancer, as given in the pathology archive records (n = 23).ResultsIn all the cases studied, 50% (n = 10) showed strong staining and 50% showed moderate staining. The percentage of staining was found to be 94.2 ± 3.1% in strongly stained cases and 92.2 ± 2.1% in moderately stained cases. Normal thyroid tissues neighboring the tumor did not display any staining.ConclusionThe MIS expression can be used as a significant tool in differential diagnosis of papillary thyroid cancer and also to shed light on its etiopathogenesis

Recurrent Retroperitoneal Cystic Lymphangioma

Retroperitoneal cystic lymphangioma is a rare congenital malformation. The majority of lymphangiomas are present at birth and nearly all present before the age of two years. We report a case of giant cystic retroperitoneal lymphangioma in a patient who first presented with symptoms at the age of 7, underwent surgery, and who then suffered a recurrent mass 11 years later

Rhabdomyosarcoma of the Upper Lip in an Adult Patient

Rhabdomyosarcoma (RMS) is a high-grade, malignant mesenchymal neoplasm. These tumors represent the most common soft tissue sarcomas of children and adolescents. RMS is uncommon on the lip and it is rarely seen in adults. Here, we report a rare case of primary RMS, embryonal type, occurring on the upper lip in a 27-year-old female

Human telomerase reverse transcriptase expression in colorectal tumors: correlations with immunohistochemical expression and clinicopathologic features

Human telomerase reverse transcriptase (hTERT) proteins in colorectal cancer investigated in several studies, but to our knowledge, hTERT expression has not been evaluated in all of colorectal tumors, including hyperplastic polyps (HPs), adenomas, and carcinomas, on paraffin-embedded tissue sections. The aim of the present study is to investigate immunohistochemical hTERT expression and its relationship with the clinicopathologic features in a spectrum of colorectal tumors. In this study, hTERT expression was determined in HP (n = 20), adenomatous polyp (AP) (n = 20), colorectal adenocarcinomas (n = 20), and normal mucosa (n = 20) by immunohistochemical method. The findings were correlated with the clinicopathologic features. The staining level of hTERT in adenomas and carcinomas was significantly higher than in normal tissues (P .05). There was no significant association of hTERT expression in cancerous, precancerous, or normal mucosa related to clinicopathologic parameters including age, sex, and size of lesion, (P > .05), but only association with histologic grade for carcinoma was found (P < .05). Levels of hTERT by immunohistochemistry demonstrated that the expression of hTERT was very little in normal mucosa and HP, moderate in AP, and highest in carcinoma. Thereby, hTERT expression may use the aggressiveness of the colorectal tumors as a marker, but it is not related to clinicopathologic data. (C) 2010 Elsevier Inc. All rights reserved

Nasobronchial interaction

WOS: 000417237300004PubMed: 26090369Upper and lower airways can be considered as a unified morphofunctional unit. In this paper, nasobronchial interactions are evaluated based on literature. To discuss nasobronchial interactions, literature review from PubMed since 1982 is evaluated. Data base was including the terms "nasobronchial interaction, nasal and bronchial". Asthma and rhinosinusitis may be associated with environmental factors and immunological predisposition. Treatment of rhinosinusitis may decrease asthma exacerbations. It was concluded that "one airway, one disease"-concept may be accepted when considering naso-bronchial interaction. Asthma treatment should also mean treating the nose as good as treating patients with nasal symptoms. To reach the succesful results it should be associated with evaluation of lung functions

Is Hyperbaric Oxygen Therapy Effective in Cisplatin-Induced Ototoxicity in Rats?

Objectives. Cisplatin is an antineoplastic agent, used in the treatment of different types of malignant neoplasms. Side effects such as ototoxicity, nephrotoxicity, and bone marrow toxicity are the main limitations of its clinical use. The aim of the present study was to evaluate the possible effects of hyperbaric oxygen (HBO) therapy as a protective agent in cisplatin-induced ototoxicity in rats

Is it always blepharitis? Urbach-Wiethe syndrome (lipoid proteinosis)

ABSTRACT A 12-year-old girl presented with recurrent crusty debris and dandruff at the base of both eyelashes despite having completed different medical treatments. She had had a hoarse voice since her early childhood. Upon anterior segment examination of the eyes, we found yellow-white, bead-like papules on the margins of the eyelids. An otolaryngologist detected multiple nodules on the vocal cords and buccal mucosa. Ultrasonography revealed salivary stones in the main parotid ducts. And a dermatological examination revealed thickened skin lesions on the elbows and knees with a biopsy showing histopathological findings of lipoid proteinosis. We diagnosed the patients as having Urbach-Wiethe syndrome or lipoid proteinosis, a rare autosomal recessive multisystem disorder with variable manifestations vary that difficult the diagnosis. The ocular manifestations are not well known among ophthalmologists, but the typical lid lesions are pathognomonic and ophthalmologists should be aware of this presentation to identify patients with Urbach-Wiethe syndrome
