Recurrent adult jejuno-jejunal intussusception due to inflammatory fibroid polyp - Vanek's tumour: a case report.

Background: Adult intussusception is a rare but challenging condition. Preoperative diagnosis is frequently missed or delayed because of nonspecific or sub-acute symptoms.

Case Presentation: We present the case of a sixty-two year old gentleman who initially presented with pseudo-obstruction.

Accuracy of the determination of S100B protein expression in malignant melanoma using polyclonal or monoclonal antibodies.

Aims: To compare the routinely used polyclonal anti-S100 and a mouse monoclonal anti-S100B antibody for their accuracy in the detection of the S100B expression profile (pattern and intensity) in a series of 67 primary (n = 37) and lymph node metastatic (n = 30) melanoma tissues. S100B is the lineage marker of malignant melanoma. Antibodies routinely used for melanoma diagnosis are not necessarily specific for this protein.

[The effect of tumour bed boost on local control after breast conserving surgery. First results of the randomized boost trial of the National Institute of Oncology].

PURPOSE: To evaluate the effect of tumour bed boost on local tumour control (LTC) after breast conserving surgery in a prospective study. METHODS: Between 1995 and 1998, 207 women with early invasive breast cancer who underwent conservative operation were treated by 50 Gy irradiation to the whole breast and then randomly assigned to receive either no further radiotherapy (n=103) or a boost to the tumour bed (n=104) with either 16 Gy electron (n=52) or 12-14.25 Gy high dose rate brachytherapy (n=52).
