The study aimed to assess a self-reported questionnaire about physical activity (PA) from the Health Behaviour in School-aged Children (HBSC) using triaxial accelerometer as a criterion. Elementary school boys (N=292) and girls (N=313) in the fourth grade and higher completed the questionnaire and wore an accelerometer for at least 10 h/day for at least 4 days. The phi coefficients of the chi-square test 2-way tables (active/inactive as measured using the HBSC questionnaire × achievement/non-achievement of the recommended 60-min moderate to vigorous PA [MVPA] as measured using the accelerometer) were 0.25 (P<0.001), 0.17 (P=0.009), and 0.08 (P=0.217) for all children, boys, and girls, respectively. The sensitivity and specificity in boys were 82% (95% confidence interval [CI]=78-86%) and 34% (95%CI=26-41%) respectively, while the those of girls were 52% (95%CI=40-63%), 57% (95%CI=55-60%). The positive predictive value in boys was 70% (95%CI=66-73%) and negative predictive value in girls was 83% (95%CI=79-87%). The independent t-test showed that moderate PA (MPA), vigorous PA (VPA), and MVPA min/day of active children were significantly higher than those of inactive children (range of Cohen’s d=0.38 to 0.71). Area under the curve (AUC) of the VPA (AUC = 0.60–0.73) in girls was significantly higher than that of the MPA (AUC = 0.52–0.65) and MVPA (AUC = 0.54–0.67). Our results supported that the HBSC self-reported questionnaire has acceptable, but limited agreement for assessing achievement/non-achievement of the MVPA recommendation, and could estimate the differences in the MPA, VPA, and MVPA min/day of children.

We report two cases of farm chemical poisoning which were treated successfully. Two elderly men separately swallowed down paraquat/diquat solutions in an attempt to kill themselves, and resultantly developed pulmonary fibrosis. After steroid therapy, clinical symptoms desappeared, although a slight degree of abnormality remained on chest X-rays. Case 1: a 57-year-old man; the amount of ingestion, 100 ml; hospitalized 2 hours after ingestion; shock, (-); urinary PQ reactoin, (2); serum PQ level, 1.14 ug/ml; pulmonary injury at first examinatoin, (-); pulmonary manifestation of symptoms, at day 3 after hospitalization; minimum Pao₂, 67.6 mmHg. Case 2: a 65-year-old man; the amount of ingestion, one gulp; hospitalized 27 minutes after ingestion ; shock, (-); urinary PQ reactoin, (3+); serum PQ level, 6.6ug/mg; pulmonary injury at first examination, (-); pulmonary manifestation of symptoms, at day 5 after hospitalization; minimum Pao₂, 58.3mmHg. For treatment, gastrointestinal lavage, forced diuresis and direct hemoperfusion were performed in both cases. Steroid pulse therapy was followed by repeated oral administration of large doses of steroid.
Hepatic and renal disorders were transient. Pao₂ was normal when the patients were discharged. The primary reasons we could save their lives are probably that the amount of PQ ingestion was relatively small, hemodialysis was performed repeatedly at early stages, and that large amounts of steroid were used immediately after the onset of pulmonary fibrosis.

We report a case of successful surgical treatment for an aortic anastomotic false aneurysm associated with a graft-duodenal fistula after abdominal aortic aneurysm repair. A 63-year-old man was admitted with melena and an aortic anastomotic false aneurysm after prosthetic graft replacement 8 years previously. CT scan demonstrated an aneurysm with a maximum diameter of 70mm at the proximal anastomotis of the prosthetic graft. Gastroduodenoscopy revealed no bleeding site in the stomach or the first and second portions of the duodenum. Therefore, we performed an emergency operation under a diagnosis of an aortic anastomotic false aneurysm associated with a graft-duodenal fistula. The aneurysm was replaced with interposition of a new prosthetic graft via a thoracoabdominal approach. The fistula was repaired by covering the duodenum with the jejunum through a left pararectal laparotomy. The postoperative course was uneventful, and there was no evidence of graft infection at 14 months after the operation.

From March 1981 to March 1990, 61 patients with Stanford type B acute aortic dissection were initially treated by conservative therapy. Among these 61 patients, the dissected lumen became occluded due to thrombosis early after diagnosis in 25 patients (Group T) and remained patent in 36 patients (Group P). Twentythree patients in Group T (92%) and 22 patients in Group P (61%) were discharged without major complications related to acute aortic dissection. However, 2 patients in Group T (8%) and 14 patients in Group P (39%) required additional surgical therapy or died during hospitalization. The mean aortic diameter at the time of admission in Group T was smaller than that of Group P (38±3mm vs 43±7mm, p<0.05). During the observation period, there was a tendency for the diameter of the dissected aorta in Group T to decrease, but to increase in Group P. Long-term survival appeared to be better in Group T than in Group P, but there was no significant difference in the overall survival curve. Large aortic diameter at the time of admission and the presence of a true thoracic aortic aneurysm were major contributing factors influencing the prognosis. A long-term follow-up study showed that the dissected lumen reduced or disappeared in 14 of 23 patients in Group T (61%) but only 2 of 16 patients in Group P (12.5%). We concluded that the patients with small dissected aortas and thrombosed dissected lumens (Group T) can recuperate only with conservative therapy. However, patients with large dissected aortas and patent dissected lumen (Group P) may require surgical therapy even in Stanford type B aortic dissection.

Angiosarcoma is an uncommon malignancy, which spread out from the endothelial cells of vessels. Scalp angiosarcoma with cervical lymph node metastasis is particularly rare. This article describes a rare case of angiosarcoma of the scalp, presenting as neck inflammation. Imaging procedures such as computed tomography (CT), magnetic resonance image (MRI) and ultrasonography (US) were not sufficient to diagnose this case. A needle biopsy provided an effective and accurate diagnosis of cervical lymph node metastasis. Additional observation and physical examination was required to diagnose the origin of the primary cancerous lesion. Once the angiosarcoma diagnosis was confirmed histologically, sequential weekly and monthly docetaxel (DTX) treatment was effective in preventing reoccurrence. Nonetheless, the optimization of angiosarcoma treatment remains a future goal. Although patients generally describe pain and swelling at the primary lesion site, this patient complained only of painful neck inflammation, without any indication of pain or swelling of the scalp. A revised diagnostic protocol should note that cervical lymph node metastasis of unknown primary origin may result from angiosarcoma of the scalp.
