Improvement of 10-year survival by Japanese radical lymph node dissection in patients with Dukes' B and C colorectal cancer: a 17-year retrospective study.

This study investigated whether the Japanese radical lymph node dissection (J-LND) method was useful for improving the survival and outcome in patients undergoing surgical resection of primary colorectal cancer. The subjects were 434 patients with primary colorectal cancer treated over 17 years. The 10-year survival (10-YS), the number of retrieved and metastatic lymph nodes (LN), the extent of lymph node dissection (D0-D3), and the extent of lymph node metastasis (n0-n4) were compared with Dukes' classification by the Kaplan-Meier curves, log-rank test and multivariate analysis.

Nondominant hand performance of the Japanese Trail Making Test and its mirror version.

Objectives: To investigate intermanual differences in the Japanese version of the Trail Making Test (JTMT) and to investigate whether a mirror version of the JTMT test sheet (JTMT-M) should be used when the task is performed with the nondominant hand.

Design: Intermanual differences were compared among the JTMT with the dominant hand, the JTMT with the nondominant hand, and the JTMT-M with the nondominant hand.

Setting: Rehabilitation center in a university hospital.

Is temporary loop colostomy of the right transverse colon appropriate for complete obstruction by colorectal cancer?

We experienced 12 consecutive cases of complete bowel obstruction due to primary colorectal cancer. Among these patients, temporary loop colostomy (loop C) was performed within the resection zone for the primary tumor in 10 cases, and Hartmann's operation was performed in two cases. The loop C was located in the sigmoid colon in five cases and on the left side of the transverse colon in five cases.

Comminuted fractures of the olecranon. Management by bone graft from the iliac crest and multiple tension-band wiring.

Between 1993 and 1999, we treated ten patients with comminuted fractures of the olecranon by multiple tension-band wiring and a graft from the iliac crest. Their mean age was 35 years (19 to 56). The mean follow-up was for 28.

Waveform of sympathetic skin response in diabetic patients.

Objective: The aim of this study was to investigate whether there were differences in amplitude and latency among the different waveform patterns of sympathetic skin response (SSR) in diabetic patients. The authors also investigated whether the proportion of the SSR waveform patterns was influenced by diabetic polyneuropathy (DP), symptoms of dysautonomia, and impaired R-R interval variation of the heart rate.

Design/methods: Twenty SSRs from palm skin were analyzed in 53 diabetic patients and 45 normal subjects.

Efficacy of oral UFT plus leucovorin therapy for colon cancer with ovarian and multiple liver metastases: report of two cases.

Case 1: a patient was diagnosed as having ascending colon cancer with right ovarian metastasis, and underwent palliative right hemicolectomy plus oophorectomy. The tumor was a well-differentiated adenocarcinoma with right ovarian metastasis, and the disease was classified as stage IV. Oral chemotherapy with UFT plus LV was performed for about 3 years, and the patient is still being followed up with no recurrence at 5 years postoperatively.

Diagnostic sensitivity of predicted F-wave latency by age, height, and MCV.

Objectives: The aim was to investigate whether minimum F-wave latency (Fmin) predicted by a multiple regression equation utilizing age, height, and motor nerve conduction velocity (MCV) (3-factor method) was clinically useful to detect Fmin abnormality in diabetic polyneuropathy (DP) and lumbosacral monoradiculopathy (RAD).

Materials And Methods: Thirty-one DP patients (ulnar, tibial, and peroneal nerves) and 66 RAD patients (peroneal nerve) were investigated. The specificity and sensitivity of the 3-factor method were compared to those obtained by a univariate (height) regression method (1-factor method) and another multivariate (height and age) regression method (2-factor method).

Relation of bimanual coordination to activation in the sensorimotor cortex and supplementary motor area: analysis using functional magnetic resonance imaging.

The aim of this study was to analyze how functional activation in the supplementary motor area (SMA) and sensorimotor cortex (SMC) is related to bimanual coordination using functional magnetic resonance imaging. Subjects included 24 healthy volunteers, 15 of whom were right-handed and 9 left-handed. Three kinds of activation tasks, all of which required the repetitive closing and opening of a fist, were performed: unimanual movement of the nonpreferred hand (task A); simultaneous, agonistic movement of both hands (task B); simultaneous, antagonistic movement of both hands (task C).
