tuberculosis is a major cause of morbidity and mortality worldwide. it is a chronic granulomatous disease that can affect any part of the body, including the oral cavity. oral lesions of tuberculosis, though uncommon, are seen in both the primary and secondary stages of the disease. this article presents a case of tuberculosis of the buccal mucosa, manifesting as non-healing, non-painful ulcer....

Fixed drug eruptions due to ibuprofen have rarely been reported. Two days after treatment with ibuprofen, a 61-year-old woman developed erythema and pain affecting the tongue and oral mucosa. Two months later, the patient started ibuprofen and erythromycin for a catarrhal episode with reappearance of the same lesions in the oral mucosa 24 hours later. Furthermore, two new erythematosus-violaceo...

one subject with isolated, fixed coronary obstruction. Three subjects with variant angina had short episodes of ischemic ST-segment elevation that lasted 20-100 seconds. Thallium scintigrams demonstrated excess uptake in regions judged to be ischemic by angiographic and electrocardiographic criteria. Two subjects, one with variant angina and the other with a fixed coronary lesion, had prolonged...

Fixed drug eruption (FDE) is a common hypersensitivity reaction characterized by recurrent, well-circumscribed, erythematous patches that arise at the same site as a result of systemic drug exposure. However, fixed food eruption (FFE), a lesion triggered by food ingestion, is a rare allergy that was first defined in 1996. Based on their anti-inflammatory and anti-oxidant properties, the fruit a...

Cats were trained to press on a lever either fixed or moving at different speeds from left to right or right to left at random. In the first series of animals, the following bilateral lesions were performed after reaching criterion on the moving lever: (1) deep cutting of cortico-cortical fibers connecting visual and frontal cortex; (2) subtotal electrolytic destruction of n. ventralis laterali...

PURPOSE OF REVIEW Fixed drug eruption is a simplified disease model for elucidating the mechanism(s) of how skin inflammation is induced by skin-resident T cells. In this review, we focus on how the presence of intraepidermal CD8+T cells resident in the fixed drug eruption lesions can provide exciting new clues to our understanding of pathomechanisms of inflammatory skin diseases. RECENT FIND...

OBJECTIVE To evaluate the clinical outcome of arthroscopic rotator cuff fixation and, when present, simultaneous repair of the Bankart lesion caused by traumatic dislocation; and to assess whether the size of the rotator cuff injury caused by traumatic dislocation has any influence on the postoperative clinical outcomes. METHODS Thirty-three patients with traumatic shoulder dislocation and co...

the papillary cystadenoma lymphomatosum (pcl), also called warthin's tumor, is a benign salivary gland tumor which primarily involves the parotid gland. these lesions are composed of a double layer of cuboidal or culmnar eosinophilic cells lining a cystic cavity which lymphoid tissue is present in the supporting stroma. the lesions shows a predilection for males, with peak incidence during...
