OBJECTIVETo explore the prevalence and characteristics of chronic headache in children and adolescents in Shanghai and to collect messages concerning the impact and compliance of medication for migraine.

METHODSA population-based questionnaire study was conducted among subjects 6 - 15 years of age sampled from primary and junior high schools in Shanghai and the subjects were followed up.

RESULTS(1) The prevalence: 8701 (88.6%) out of 9857 pupils responded to the questionnaire; 17% of the respondents had headache and in 86.4% of them the reason of headache was unknown. The prevalence of chronic headache in Shanghai children and adolescents was 7.8%, there was no significant difference between both genders (chi(2) = 0.010, P > 0.05). (2) The prevalence of chronic headache increased with age, the incidence was higher in boys before 12 years of age, while higher in girls after 12 years of age. (3) Characteristics of chronic headache: the proportion of unilateral, bilateral and headache of unknown site was similar; in most of the cases headache was localized in the temple (35.2%) and forehead region (25.6%), the duration of headache was short, always accompanied by gastrointestinal symptoms. Half of the patients reported that the headache had affected their study and daily life. (4) The status of using health care facilities: 24% of the students sought medical assistance during their headache episodes and among them only 30.9% took medicine. (5) Over-fatigue (51.4%), followed by insufficient sleep (40.4%), emotional changes (38.5%) were the main aggravating factors. The headache was also associated with positive family history and stress in studying.

CONCLUSIONSHeadache is a common complaints of children, affecting the patients' study and daily life. But many patients with headache were not treated properly, therefore, the medical and educational sectors and the society should pay more attention to this problem.

BACKGROUNDNoise is widespread occupational hazard in iron and steel industry. Overhead-traveling cranes are widely used in this industry, but few studies characterized the overhead-traveling crane drivers' noise exposure level so far. In this study, we assessed and characterized personal noise exposure levels of overhead-traveling crane drivers in two steel-rolling mills.

METHODSOne hundred and twenty-four overhead-traveling crane drivers, 76 in the cold steel-rolling mill and 48 in the hot steel-rolling mill, were enrolled in the study. Personal noise dosimeters (AIHUA Instruments Model AWA5610e, Hangzhou, China) were used to collect full-shift noise exposure data from all the participants. Crane drivers carried dosimeters with microphones placed near their collars during the work shifts. Work logs had been taken by the drivers simultaneously. Personal noise exposure data were divided into segments based on lines in which they worked. All statistical analyses were done using SPSS 13.0.

RESULTSThe average personal noise exposure (L(Aeq.8h)) of overhead-traveling crane drivers in the hot steel-rolling mills ((85.03 +/- 2.25) dB (A)) was higher than that in the cold one ((83.05 +/- 2.93) dB (A), P < 0.001). There were 17 overhead traveling cranes in the hot steel-rolling mill and 24 cranes in the cold one, of which carrying capacities varied from 15 tons to 100 tons. The average noise exposure level based on different lines in the hot and cold steel-rolling mills were (85.2 +/- 2.61) dB (A) and (83.3 +/- 3.10) dB (A) respectively (P = 0.001), which were similar to the average personal noise exposure in both mills. The noise exposure levels were different among different lines (P = 0.021).

CONCLUSIONNoise exposure levels, depending upon background noise levels and the noise levels on the ground, are inconstant. As the noise exposure levels are above the 85 dB (A) criteria, these drivers should be involved in the Hearing Conservation Program to protect their hearing.

OBJECTIVETo employ reverse first dorsal metatarsal artery island flap to recover the donor site of great toe after free lateral pulp flap transfer, and decrease the morbidity of microsurgical donor site.

METHODSFrom February 2000 to June 2004, 12 cases of soft tissue defect in thumb and finger were treated by free lateral pulp flap of great toe transplantation, and that the secondary defect of great toes were repaired by reverse first dorsal metatarsal artery flap according to the anatomical communicating between first dorsal metatarsal artery and plantar metatarsal artery. The donor exposure of dorsal pedis were straightly sutured.

RESULTSAll the lateral pulp flaps of great toe and the reversed first dorsal metatarsal flaps survived uneventfully with desirable appearance and sensation. In thumb and finger defect reconstructed with lateral pulp flaps of the great toe, there was in mean static two-point discrimination of 6 mm at 10 month follow-up, that was 10 mm in reverse flaps.

CONCLUSIONSIt is an instructive and practical creation to adopt the reverse first dorsal metatarsal artery flap to recover the raw surface in the lateral aspect of the great toe, which minimizes the morbidity at the donor site and gains the twin-win results.

OBJECTIVETo measure and evaluate the personal noise exposure of cold rolling mill workers by using noise dosimeter.

METHODSAccording to job category and work type, all workers were divided into 11 groups. 3 to 5 day shift (8:00 to 16:00) workers from each group were selected as subjects for personal noise exposure measurement. SH-126 dosimeters were worn by each subject and collect noise data by a phone fix at collar. All subjects were asked to take notes about their working activities when they were wearing SH-126 dosimeters. Each worker's L(A)(eq) of 8 hours, geometric mean and range of each group were computed.

RESULTSThere were many noise sources in the workshop. Recorded data showed that noise exposure of cold rolling mill was unstable. The varieties of personal noise levels were quite large. Among 53 workers, the highest noise exposure level was 100.0 dB (A), the lowest was 81.2 dB (A); the highest work type was of the foreside welders [94.20 dB (A)], and the lowest was of the straight-cutters [89.02 dB (A)]; quality checkers had the biggest rang [16.3 dB (A)], and primary rolling workers had the lest [2.3 dB (A)].

CONCLUSIONNoise exposure of all the 11 groups were more than 85 dB (A). Noise protection of these workers should be improved. It suggested that measuring personal noise exposure individually with dosimeters might obtain the noise exposure level more integrally in the complicated environment.
