Sinonasal T-cell lymphoma a case report

Lymphomas may be defined as neoplastic proliferations of the lymphoreticular system cells. T-cell lymphoma is histologically characterized by angiocentricity with invasion and blockage of blood vessels by lymphoma cells resulting in marked ischemic necrosis of the normal and neoplastic tissues. A case report of sinonasal T-cell lymphoma in a 30 year old male patient was presented. Initial diagnosis was misplaced as orbital cellulites with acute pan sinusitis delayed proper investigation and management of the case. Diagnosis by routine means is often found to be difficult, but with the advance in immunocytochemical phenotyping and molecular genetics, this problem was resolved and prognosis and management improved. Treatment modality for this lesion is radiotherapy with or without chemotherapy. Although prognosis is not very promising, this regimen gives the best possible result

Periodontal evaluation during active orthodontic treatment

The aim of this study is to evaluate the periodontal status during orthodontic tooth movement, using fixed orthodontic appliance. PATIENTS AND METHOD: Eighty four male and female patients were randomly selected from orthodontic clinic in King Abdulaziz Air Base Hospital in Dhahran [KAABH] during activation visits. Periodontal clinical examination was conducted using PI [Silness and Loe 1964], GI [Loe and Sillness 1963], and crevicular measurements by PDI [Ramfjord 1959]. It was found that the majority of the cases [70.2%] had moderate amount of plaque deposits. In parallel, [85.7%] of the sample showed moderate gingival inflammation with bleeding on probing. Gingival enlargement was evident in almost half of the cases [51.2%] while recession occured in only [12%]. Within the limitation of this study it can be concluded that fixed orthodontic appliance might be a predisposing factor for plaque accumulation and subsequent gingival inflammation. Also, gingival enlargement is a common finding within orthodontic patients while recession can occur in few cases. Lower anterior teeth were at the highest risk of periodontal problems during active orthodontic therapy

Effect of sanguinarine on the bacterial colonization and gingival health of overdentures abutments

Sanguinarine, a component of sanguinaria extract, was evaluated for its effect on the bacterial colonization and gingival health of over dentures abutments which are considered essential for maintaining the alveolar ridge. Twenty five patients were recruited in this study using a double-blind cross-over fashion to compare Sa with SnF2 which has been recommended as a daily home care for preservation of over-dentures abutments
