Introduction Warthin tumor is described as papillary cystadenoma lymphomatosum and is the second most common tumor of the parotid glands. Bilateral synchronous incidence is rare, occurring in 7 to 10% of the cases. It is more common in males between 60 and 70 years of age and is closely related to smoking. There is slow growth and the condition is a delimited nodule of regular outlines; it has ...

BACKGROUND Bronchial intraepithelial lesions may be precursors of central airway lung carcinomas. Identification and early treatment of these preinvasive lesions might prevent progression to invasive carcinoma. METHODS We systematically reviewed the literature to develop evidence-based recommendations regarding the diagnosis and treatment of intraepithelial lesions. RESULTS The risk and tim...

BACKGROUND The purpose of this study was to investigate the presence of punched-out lesions in craniofacial bones using three different radiographic protocols in a large cohort of patients. MATERIAL AND METHODS One hundred fifty-five MM patients were evaluated using panoramic and skull (frontal and lateral) radiographs, which were performed in all patients at the time of MM diagnosis. The dia...

BACKGROUND Choosing the most effective approach for treating rectal cancer with mesorectal fascia (MRF) involvement or closeness and synchronous distant metastases is a current clinical challenge. The aim of this retrospective study was to determine if upfront systemic chemotherapy and short-course radiotherapy (RT) with delayed surgery enables R0 resection. METHODS Between March 2009 and Oct...

BACKGROUND The prevalence of esophageal neoplasia in head and neck (H&N) cancer patients is not low; however, routine esophageal surveillance is not included in staging of newly-diagnosed H&N cancers. We aimed to investigate the risk factors for synchronous esophageal neoplasia and the impact of endoscopy on management of H&N cancer patients. METHODS A total of 129 newly diagnosed H&N cancer ...

We consider the problem of synthesizing correct-by-construction globally asynchronous, locally synchronous (GALS) implementations from modular synchronous specifications. This involves the synthesis of asynchronous wrappers that drive the synchronous clocks of the modules and perform input reading in such a fashion as to preserve, in a certain sense, the global properties of the system. Our app...

BACKGROUND Up to 15% of all patients with brain metastases have no clearly detected primary site despite intensive evaluation, and this incidence has decreased with the use of improved imaging technology. Radiosurgery has been evaluated as one of the treatment modality for patients with limited brain metastases. In this study, we evaluated the effectiveness of radiosurgery for brain metastases ...

AIM Assessment of the efficiency of 18F-FDG-PET (PET) for the detection of distant metastases and synchronous primary malignancies in patients with oral and oropharyngeal squamous cell cancer (OOSCC). PATIENTS, METHODS Retrospective evaluation of PET studies of 422 patients with histologically confirmed OOSCC. 99 patients (23.5%) demonstrated a suspect distant finding of whom 84 could be inte...
