Alveolar soft part sarcoma is a rare type of sarcoma that usually affects young adult women. It occurs mostly in the lower extremities, and nearly one quarter of the cases are found in the head and neck region. The most common site of origin in the head and neck region is the tongue followed by the orbit. Herein, we present an unusual case of alveolar soft(More)
In order to evaluate the injurious effect of hyperoxaluria on renal tubular epithelium, as judged by apoptotic changes in the renal parenchyma, we performed an experimental study in 20 rabbits. In the experimental group animals (n=10) severe hyperoxaluria was induced by continuous ethylene glycol (EG; 0.75%). Histologic alterations, including crystal(More)
Renal tubular epithelium is the major target for oxalate induced injury, and sustained hyperoxaluria together with CaOx crystal formation/deposition may induce renal tubular cell damage and/or dysfunction. This may express itself in cell apoptosis. To evaluate the possible protective effects of certain agents (vitamin E, potassium citrate, allopurinol,(More)
OBJECTIVE The aim was to discuss the balance between free radical damage and body defense mechanisms that occurred in reexpansed pulmonary tissue and to evaluate the relationship between the changes in the pulmonary circulation and the mentioned balance. METHODS Twenty male Wistar Albino rats were used for these study results. Pneumothorax was created in(More)
OBJECTIVES To elucidate the clinical and histopathological significance of the proliferative activity as determined by PCNA and Ki67 levels and mitotic counting (MC) in laryngeal squamous cell cancer (LSCC). STUDY DESIGN An analysis of clinical, histopathological and immunhistochemical (PCNA0 and Ki67) results of 28 patients, who were treated for LSCC,(More)
Vocal cord paralysis is a disease that can cause voice disability and aspiration problems. Expanded polytetrafluoroethylene (ePTFE; Gore-Tex) has been widely used in cardiovascular and plastic surgery; however, its biocompatibility and safety have not been established precisely in the larynx. In this study, the biocompatibility and safety of ePTFE used in(More)
Pleomorphic adenoma is the most common benign tumor of the salivary glands, mainly arising from major salivary glands such as parotis and submandibular gland. In rare cases, however, pleomorphic adenoma presents in various unusual sites such as the nasal cavity, paranasal sinuses, hypopharynx, pharynx, larynx, trachea and lacrimal glands. We present a rare(More)
Nongestational choriocarcinoma of the ovary is a germ cell tumor with a worse prognosis than gestational choriocarcinoma. In this report we present a nongestational choriocarcinoma that was referred to our hospital as an ectopic pregnancy. The clinical features, management, and outcome are discussed.
OBJECTIVE To evaluate the possible protective effect of verapamil (a calcium channel blocking agent) against the traumatizing effects of high-energy shockwaves (HESW) and new stone formation, as indicated by crystal deposition in the renal parenchyma, an experimental study was performed in rabbits. METHODS A total of 65 rabbits were included. During(More)
In this experimental study, it was our aim to reduce the effects of ischemic insults to the contralateral testicle after unilateral testicular torsion. The protective effect of a calcium channel blocking agent (verapamil) on the histology and the tubular diameter of contralateral testicle was evaluated. Following a definite period of unilateral testicular(More)
