ObjectiveTo investigate the annual average myopic growth of different-aged youngsters in recent years. MethodsBetween July 2010 and September 2011, 103 myopic youngsters (206 eyes) aged 7 to 18 years were recruited at the Ophthalmologic Department in West China Hospital. We measured their myopic diopter, and let them wear normal spectacles according to the measurement, and then measured their myopic diopter again half a year later. The difference between the two measurements was recorded and analyzed. ResultsThe male group increased (-0.82±0.44) D per year, and the female group increased (-0.99±0.57) D per year, and the difference between the two groups had statistical significance (P<0.05). The male of 7 to 10 years old increased (-0.97±0.39) D per year, and of 11 to 14 years old increased (-0.92±0.41) D per year, and of 15 to 18 years old increased (-0.49±0.37) D per year, and the differences among the three male groups had statistical significances (P<0.01). The female of 7 to 10 years old increased (-1.22±0.46) D per year, and of 11 to 14 years old increased (-0.84±0.47) D per year, and of 15 to 18 years old increased (-0.61±0.67) D per year, and the differences had statistical significances (P<0.01). ConclusionThe annual myopic growth of youngsters is related with age and sex. The growth of the female is faster than the male, and the younger also grows faster.
ObjectiveTo introduce the surgical method and effectiveness of repairing skin and soft tissue defect in the palm or dorsum of the hand and forearm with epigastric bilobed flap. MethodsBetween October 2010 and December 2013, 4 male patients with skin and soft tissue defect in the palm or dorsum of the hand and forearm were treated, aged from 36 to 62 years. Of them, 3 cases had degloving injury caused by machines and 1 case had necrosis of fingers and skin after surgery of crush injury. The time from injury to hospitalization was from 3 hours to 15 days. Among the 4 cases, the size of palmar defect was 7 cm×4 cm to 16 cm×6 cm, and the size of dorsal defect was 10 cm×7 cm to 20 cm×10 cm. The epigastric bilobed flap was designed based on the axial vessel which was formed by inferior epigastric artery, superior epigastric artery, and intercostals arteries. The size of flap ranged from 12 cm×4 cm to 18 cm×6 cm in the vertical direction, 15 cm×8 cm to 22 cm×11 cm in the oblique direction. The donor site was directly closed. The pedicles were cut at 22 to 24 days after repairing operation. ResultsAll the flaps survived well with the wound healing by first intention. Four patients were followed up 3 months to 1 year and 2 months. The other flaps had good appearance and texture except 1 bulky flap. The flap sensation basically restored to S2-S3. The function of the hands recovered well. ConclusionSkin and soft tissue defect in the palm or dorsum of the hand and forearm can be repaired with the epigastric bilobed flap, because it has such advantages as big dermatomic area and adequate blood supply. Besides, the operation is practical, safe, and simple.
