Until recently, squamous-cell carcinoma comprised the vast majority of cases of esophageal cancer. However, the incidence of adenocarcinoma in white males has been rapidly increasing by approximately 10% per year for the past 10 years. This percentage increase in frequency exceeds that of all other cancers for that time period.[2,3] The prognosis for patients with either type of tumor histology...

Modality is an important, but complex linguistic phenomenon that concerns all levels of language production. NLP research has rather refrained from this subject, but we show that many errors in machine translation systems are directly related to the absence of a proper interlingual treatment of modality. We outline the traces of such a modal interlingua by presenting the “Module of Modality”, p...

Oral submucous fibrosis (OSMF), which presents with a severe degree of trismus, is a great surgical challenge. The surgical procedures include excision of fibrous bands with or without coverage of the surgically created defect. The use of vascularised flaps such as the palatal pedicled flap, tongue flaps, use of buccal fat pad and nasolabial flaps are becoming increasingly popular. We present a...

Diagnosis and treatment planning for dental implants has dramatically improved over the past three decades. Today's imaging technologies allow clinicians to assess individual patient-specific anatomy before the scalpel ever touches the patient.

Substantial clinical progress over the last decades has improved the first-line treatment and prognosis of patients with Hodgkin's lymphoma (HL). This success is mainly based on the introduction of combined modality treatment strategies including chemotherapy in all risk groups and important progress in radiation techniques. The knowledge emerging from numerous clinical trials as well as better...

This paper describes the mechanisms of action of ionizing radiations combined with antineoplastic drugs. Some relevant drugs for the combined modality treatments of locally advanced lung cancer are reported. The meta-analyses including randomized trials comparing single agent (radiotherapy or chemotherapy) versus combined chemotherapy and radiotherapy in patients with unresectable non small cel...
