[Questionnaire research of the participants in a large scale walking event Fukuoka City analysis of walking habits and related factors].

PURPOSE: We examined the walking habits of the participants in the 'AIREF Spring Walk' which was held on March 9, 1997 in the western suburb of Fukuoka City. The aim of this walking event was to motivate the citizens, especially sedentary people, to walk by providing them an opportunity to enjoy walking. METHODS: The participants walked one of three distances (5 km, 10 km or 20 km) and answered anonymously a questionnaire immediately after finishing (100% response rare). The questionnaire items covered sex, age, district of residence, the distance of the walking course, the source of information on the event, experience of participating in other walking events in the past, and walking habits. RESULTS: The participants of this event (n = 1,039, mean age 49.4 +/- 18.9 [SD] years) were characterized by high rates for females (67%), those aged < 50 years (42%), residents of Fukuoka City (89%), those who chose to walk the shorter courses of 5 or 10 km (74%), and those who took part in a walking event for the first time (61%). Information on the event was obtained through other people (32%) such as friends, acquaintances, members of community walking groups or other family members, leaflets (21%) placed in the Fukuoka Health Promotion Center and seven Fukuoka City public health centers; a newspaper published biweekly by the municipal government (13%); and direct mail (11%). For those attending the 5 km course, more participants learned about the event through other family members compared with the other two courses. Participants who answered that they walked regularly constituted 56% of those aged 20 years or older. The rates for regular walkers significantly increased with the older participants (p < 0.01) and those who chose longer courses (p < 0.001). Compared with the regular walkers, those without a walking habit tended to have acquired information on the event from friends, acquaintances or other family members, or at their work sites (35%). The average amount of time spent was 249 +/- 175 min/week (n = 375). As a whole, only 30% of the participants aged 20 years or older walked longer than the amount of time for aerobic exercise recommended by the Health, Labor and Welfare Ministry (HLWM). The rate for those who reached the HLWM recommendations was increased in older subject (p < 0.001). CONCLUSIONS: It is concluded that the aim of the walking event was partly accomplished, which was reflected by the relatively high rates of participation sedentary for people, compared with other large walking events. The sedentary participants tended to choose the relatively short distances and obtain the information about the event through other people. Walking promotion programs should be developed to motivate sedentary citizens to walk. The programs should also support regular walkers, many of whom are 50 years old or older, to maintain walking habits with the HLWM recommendations on aerobic exercise.

Translocation (3;21)(q26;q22) in treatment-related acute leukemia secondary to acute promyelocytic leukemia.

We performed cytogenetic studies in a patient with treatment-related acute leukemia (t-AL) to identify the associated chromosomal changes. Metaphase analysis revealed a t(3;21)(q26;q22) translocation. Acute promyelocytic leukemia (APL) had been diagnosed 4 years earlier and the patient had received intensive induction chemotherapy and sequential post-induction therapy that included agents that targeted DNA-topoisomerase II (topo II). This case suggests an association between previous therapy with topo II inhibitors and development of t-AL associated with a balanced aberration involving the 3q26 and 21q22 bands.

[Multiple hepatosplenic abscesses: successful treatment by continuous intraportal administration of amphotericin B in a case with acute promyelocytic leukemia].

A 40-year-old female was admitted in August 1989 with a diagnosis of acute promyelocytic leukemia (AML; M3). One course of modified-DCMP regimen induced complete remission in September, but she developed spiking fever at a nadir period of WBC after induction chemotherapy. CT revealed multiple hepato-splenic abscesses presumably due to candida infection. She was treated with intravenous administration of amphotericin B (AMPH-B) and other antifungal agents. Despite the hematological remission and prolonged use of these antifungal agents, high fever persisted. A catheter was inserted into the portal vein under ultrasonic-guidance. AMPH-B was administered through the catheter: the initial dose was 3 mg/day and was soon increased to 20 mg/day. Her fever subsided in 1 week, and the sizes of liver abscesses on CT reduced markedly. Chill and hypokalemia were observed during this therapy. The catheter was removed from the portal vein after 29 days. Partial portal vein thrombosis was noted around the catheter tip. This case suggests the usefulness of intraportal administration of AMPH-B in patients with hematological malignancy developing multiple liver abscesses.
