Axillary reverse mapping for breast cancer.

The axillary reverse mapping (ARM) technique has been developed to map and preserve arm lymphatic drainage during axillary lymph node dissection (ALND) and/or sentinel lymph node (SLN) biopsy, thereby minimizing arm lymphedema. However, several problems remain to be resolved in the practical application of this technique. This article presents a review of current knowledge regarding ARM and discusses the practical applicability and relevance of this technique.

[A case undergoing repeated anaphylactic shock after systemic administration of vinorelbine].

We here describe a 49-year-old man who suffered repeated anaphylactic shock after systemic chemotherapy with vinorelbine for stage IV left lung adenocarcinoma (S1+2). He was treated using a combination of cisplatin and weekly irinotecan (CPT-11) as the first line; however, the regimen was changed to a combination of vinorelbine (VNR) and gemcitabine (GEM) because of his progressive disease. He was admitted to our hospital for examination of the unknown cause of hypotension and loss of consciousness.

[Role of T cells in the pathogenesis of type I diabetes mellitus: structure analysis of complementarity determining region 3 of circulating T cells].

Type 1 diabetes mellitus (type 1 DM) is the disease of insulin deficiency due to the destruction of islet cells of the pancreas, presumably through the pathogenic process mediated by autoreactive T cells. In many autoimmune diseases, oligoclonal expansion of autoreactive T cells have been reported recently. It is also suggested that proliferation of T cell clones which recognize pancreatic beta cell antigen are involved in the pathogenesis of type 1 DM.

[Extraction of RNA from paraffin embedded tissues and analysis of p53 gene expression in colonic cancer].

We examined, immunohistochemically and molecular biologically, p53 gene expression in 10 patients with colonic cancer. RNA was extracted from paraffin embedded normal and colonic cancer tissues by using RNA isolator kit and proteinase K. The most effective time and concentration of proteinase K for RNA extraction was 24 hours and 100 micrograms/ml, respectively.

Arthroscopic eminoplasty for habitual dislocation of the temporomandibular joint: preliminary study.

A unique surgical technique, arthroscopic eminoplasty was undertaken in 16 joints of 11 patients with habitual dislocation of the temporomandibular joint (TMJ). There were 10 joints with subluxation and 6 joints with complete dislocation in 4 male and 7 female patients with a mean age of 33 +/- 20 years. The procedure consisted of conventional diagnostic arthroscopy, followed by shaving of approximately 3 to 5 mm in height of the articular eminence with an electric motorized shaver with bone files, depending on the bone thickness as detected by preoperative imaging.

Incrustation and uptake of skeletal imaging agent in transitional cell carcinoma.

We present a case of transitional cell carcinoma of the bladder visualized by 99mTc-HMDP bone scintigraphy and suggest possible uptake mechanisms. Pelvic CT demonstrated a sessile bladder tumor with punctate and curvilinear calcifications on the surface areas (incrustation). Technetium-99m-HMDP bone scintigraphy demonstrated intense uptake corresponding to the site of the bladder tumor.

[Detection of nucleotide mutation by direct sequencing method using non-radio isotopic marker].

We report a protocol which can analyze DNA by the dideoxy method. First, we prepared DNA from paraffin specimen of colon cancer and normal tissue by the method using proteinase and phenol. Polymerase chain reaction (PCR) was performed as follows.

[Pathologic diagnosis on bone and soft tissue tumors by molecular biological methods].

Characteristic chromosome aberrations and the rearranged genes resulting in chimeric fusion genes have been reported in some bone and soft tissue tumors; t(X; 18) in synovial sarcoma, t(11; 22) in Ewing's sarcoma and primitive neuroectodermal tumor, and t(2; 13) in alveolar rhabdomyosarcoma. We practically used the chromosome analysis and the reverse transcription-polymerase chain reaction (PCR) method as a tool for diagnosis and follow up. All of 10 cases of synovial sarcoma had a chimeric product of SYT/SSX gene.

[Echocardiographic assessment of the etiology of aortic regurgitation in the elderly].

We performed echocardiographic studies in 189 elderly subjects aged over 65. Aortic regurgitation (AR) was detected by real time 2-D Doppler system. 189 patients were classified into 5 groups based on the severity of AR (AR-: 81 pts, AR1+: 32 pts, AR2+: 44 pts, AR3+: 27 pts, AR4+: 5 pts).
