ABSTRACT
Objective To discuss the clinical influence and advantages of applying the local flap of finger tip lateral skin to repair the fingertip defective injuries.Methods From August,2013 to December,2015,used the way of local the flap of finger tip lateral skin to repair the first-fourth fingertip defects for 32 cases and 32 fingers,among which there were 20 males and 12 females;finger categories:11 thumbs,9 index fingers,8 middle fingers and 4 ring fingers.The defective area of fingertips was 0.5 cm×0.8 cm-1.0 cm×1.5 cm,all with bone exposure,23 cases had defects at the end part of phalanx,32 cases had different extent of nail bed defects.Reasons for the injuries:13 cases of grind injuries,11 cases of punch pressing injuries,8 cases of sharp tool cutting injuries.The time from injury to the treatment was 0.5-3.0 h,all of them had no associated injuries.Results Thirty-two cases of finger flaps all survived,with the follow-up for 3-24 months and average follow-up of 6 months,the flaps were slightly bloated after 3 months comparing with the normal skin,there was no contracture in the flap area and pedicle scars,two-point discrimination was 4-5mm,the farinterphalangeal joint flexion was normal.Conclusion The local flap of fingertip lateral skin can repair the defects of fingertip with less scar,not bloated flap,satisfying appearance,operation is simple,and good function,so it's the ideal way to repair the defects of fingertip.
ABSTRACT
Objective To summarize the cytological features of breast carcinoma by fine needle aspiration and differential diagonsis of breast hyperplasia and breast flbroadenoma. Methods Cytological features about 175 cases of breast cancer were analyzed,contrasted with 76 cases of breast hyperplasia and 93 eases of fibroadenoma. And 20 cases of low-diagnosis breast cancer were analyzed, compared with 13 cases of excessive diagnosis. Results The followings were found:disorderly arranged cells in 169 cases of breast cancer, about 96.9% in 175 cases,loose distance between the nucleus in 125 cases of all cases (about 71.4%). The percentage of small groups or scattered cells, medium size cells, round nucleus and irregular border nucleus was 34.3% (60/175) ,81.1% (142/175), 88.6% (155/175) and 28.6% (50/175) respectively. The nucleus/cytoplasm ratio was increased in 105 cases of all (about 60%). The nucleus/cytoplasm ratio was obviously reduced in 15 cases of all (about 8.6%). Big nucleolis were observed in 49 cases of all (about 28%). There was significant difference between nucleus size in 136 cases of all (about 77.7%). There was not myoepithelial cell in 168 cases of all (about 96%). The percentage of visible necrosis, scsttered round nucleus and integrity of cytoplasmic was 13.7% (24/175) ,89.7% (157/175), 66.9% (117/175) respectively. The cases of all above features were significantly more than those of breast hyperplasia and breast fibroadenoma (P <0.05). The percentage of large number of cells was 52.6% in 175 breast cancer cases,higher than 5.3% in 76 breast hyperplasia cases. There was a significant difference(P <0.05) between two groups. In 20 cases of low-diagnosis breast cancer the percentage of round nucleus with integrity of cytoplasmic, special arrangement cells was 70% (14 cases) ,35% (7 cases) ,higher than the cases in 13 excessive diagnosis cases. There was a significant difference(P < 0.05) between two groups. Conclusion The cell morphological characteristics of breast caner by fine needle aspiration are large number of cells, loose distance between the nucleus, disorderly arranged cells, small guoups or scattered cells, integrity of cytoplasmic, increased nuclear, round nuclear, irregular border nucleus,increased or decreased nucleus/cytoplasm ratio, big nucleoli, significant difference in nuclear size, no myoepithelial cell, visible necrosis. Most of breast cancer can be distinguished from breast hyperplasia and breast fibroadenoma by above characteristics. All those cytological characteristics are helpful to identify difficult case.
