the peutz-jeghers syndrome is characterized by an association of gastrointestinal polyposis with rnelain spots on oral mucosa, lips, and skin. this symdrorne is inherited as a simple mendelian autosomal dominant trait. intussusception is by far the most common complication. although these polyps are widely regarded as hamartomas and rarely undergo malignant change, they have been reported to be...

Introduction: Brachytherapy, especially using manually after loaded Iridium-192 and Cobalt-60, can be applied as a sole treatment, as a treatment complementary to surgery, and as a local boost in combination with EBRT. The use of HDR brachytherapy catheters incorporated in removable dental molds allows repeated, highly reproducible, fractionated outpatient brachytherapy of supe...

UNLABELLED Many studies have shown an association between actinic cheilitis and squamous carcinoma of the lips. AIM The aim of the study was to observe the relation between actinic cheilitis and the prognosis of squamous carcinoma of the lips. MATERIALS AND METHODS This is a retrospective cross-sectional cohort study of squamous carcinoma of the lips. Histological sections of squamous carcino...

Lips are structures that play an essential role in aesthetics and in different functions such as nutrition and speech. The complex anatomy of the lips - with three different layers composed of skin, mucosa, and muscles - makes surgical management of this area a therapeutic challenge. The use of flaps for the reconstruction of large defects with low risk of necrosis is possible given the abundan...

Spindle cell carcinomas are biphasic tumors of monoclonal origin with mesenchymal component proved to be the dedifferentiated forms of conventional squamous cell carcinomas. This unusual variant of squamous cell carcinoma usually presents in the larynx, but are also infrequently reported in the gingiva, tongue, lips, hypopharynx and nasal cavity. We report a spindle cell carcinoma of buccal muc...

It has been nearly 15 years since the term ‘large igneous province’ was introduced by Mike Coffin and Olaf Eldholm (1991, 1994). An umbrella term to include continental flood basalt provinces, oceanic plateaus, volcanic rifted margins and aseismic ridges, it rapidly entered common parlance even though it was, and remains, loosely defined. The key aspect of large igneous provinces (LIPs) is that...

Background and Aim: Oral mucosal lesions have various prevalence rates among different populations. Few studies have evaluated the frequency of oral mucosal lesions in Iranian population. This study aimed to determine the frequency of oral mucosal lesions and the related factors.                   &nb...

In recent years, many approaches have been suggested for Internet and web streaming detection. In this paper, we propose an approach to signal waveform detection for Internet and web streaming, with novel statistical automatons. The system records network connections over a period of time to form a signal waveform and compute suspicious characteristics of the waveform. Network streaming accordi...
