Early esophageal cancer is defined as a tumor invading the mucosa with or without lymph node or distant organ metastasis. In the current guidelines for early esophageal cancer, absolute indication for endoscopic resection include lesions limited to the epithelium or lamina propria mucosa not exceeding two-thirds of the circumference, and relative indications include lesions limited to the muscu...

Functional and aesthetical reconstruction, especially of the upper lip after ablative tumor surgery, can be very challenging. The skin of the lip might be sufficiently reconstructed by transpositional flaps from the nasolabial or facial area. Large defects of the lip mucosa, including the vestibule, are even more challenging due to the fact that flaps from the inner lining of the oral cavity of...

The incidence of Helicobacter pylori and non-steroidal anti-inflammatory drug (NSAID)-negative peptic ulcer disease has increased over the last two decades, especially in the Western world and in countries with low H. pylori infection rates. Idiopathic peptic ulcer disease is a recently described entity which relates to peptic ulcers not caused by H. pylori, NSAID/aspirin therapy, other ulcerog...

B asal cell carcinoma (BCC) involving the vermilion border and mucosal surface of the lips is rare, whereas these sites are more frequently involved by squamous cell carcinoma (SCC). The epithelium of the lip is divided into 4 regions: the skin; the vermilion border; the outer mucosa (vermilion); and the inner mucosa. The vermilion border contains the orbicularis oris muscle without a subcutane...

Purpose Myocutaneous flaps were commonly used to repair the mucosal defect that results from ablative tumor surgery. However, skin is not a perfect substitute for the oral mucosa because it can lead to poor hygiene due to hair growth and desquamation. The myodermal flaps used for the reconstruction of mucosa in oncologic surgery of the oral cavity. Material and method Pectoralis major and platy...

adenoid cystic carcinoma (adcc) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). about 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). three clinically obvious characteristics of adcc include slow growth rate, perineural invasion and high incidence of distant metastasis (1). the most commonly-affected sites of...

squamous cell carcinoma (scc) of the buccal mucosa accounts for 23% to 37% of all intraoral cancers, the prognosis is generally poor. we reported a case of local invasion of buccal squamous cell carcinoma. a 32-year-old man referred to the clinic with a chief complaint of swelling in the right cheek region that initiated from 6 months ago and rapidly grow from one month ago. history of the pati...

The present research work was conducted to study about the seroprevalence and pathology of Salmonella infections in layer chickens of Dhaka and Gazipur regions of Bangladesh and to isolate and characterize Salmonellae from layer chickens during the period from January to May 2006. The used materials were blood sample, cloacal and liver swabs from live and dead birds respectively, and visceral o...

Mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. Carbomers are among the best mucosa-adhesive materials known. The aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing Carbomers, either alone or in combination, to the data obtained from assessing the d...

To determine whether the colonic epithelial proliferation rate is useful as a marker for colorectal cancer, we measured the Ki-67 labeling index (LI) in normal-appearing mucosa from the sigmoid and ascending colon in patients with two or more tumors (early cancers, which are defined as tumors the depth of invasion of which is limited to mucosal layer or submucosal layer, adenomas, or both). The...
