MSCT diagnosis of tumors of intra-abdominal cryptorchidism in children / 中国医学影像技术

Objective To explore the diagnostic value of MSCT in tumors of intra-abdominal cryptorchidism in children.Methods MSCT findings of 8 children with tumors of intra-abdominal cryptorchidism confirmed by surgery and pathology were analyzed retrospectively.Results Six tumors located in the right,2 (1 tumor of left cryptorchidism turned to the right abdominal) in the left.Eight children showed ovoid soft tissue tumor in abdomen.Three children displayed the long axis of the tumors consistent with regular descending course of embryonic testes.Six teratomas manifested as the cystic and solid mass with fat,calcification (ossification) insidey.Two yolk sac tumors manifested as the large cystic and solid mass with irregular necrosis and abundant tumor vessels.Conclusion The pathologic types of tumors for intra-abdominal cryptorchidism in children are different from adult.Most of them are teratomas or yolk sac tumors,and have some characteristics in MSCT.MSCT is helpful in diagnosis of tumor for intra-abdominal cryptorchidism with medical history.

Multiple reoperation of recurrent maxillofacial huge dermatofibrosarcoma protuberans / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To Summary the experience of surgical treatment for many times in 1 case of maxillofacial huge dermatofibrosarcoma protuberans.@*METHOD@#The patient was diagnosed with dermatofibrosarcoma protuberans according to the pathological examination. From 2004 to 2011, the patient underwent extensive surgical resection, Mohs micrographic surgery(MMS) and free flap grafting method as surgical treatment for many times, and was closely followed-up after operation.@*RESULT@#The tumor was completely removed in each operation, with wound skin graft survived. But relapse occured repeatedly, recurrence interval was from 7 months up to five years and eight months,recurrence interval gradually extended, all of the recurrence occurred at Mohs microsurgery cut edge.@*CONCLUSION@#Eexpanded resection is the preferred treatment for the early stage maxillofacial huge dermatofibrosarcoma protuberans. For advanced stage tumor, expanded resection should be combined with Mohs microsurgery. Free flap grafting was suggested in primary repair insteading of myocutaneous flap. At the same time, postoperative assistant radiotherapy, strengthen follow-up and early intervention were suggested.

Nasal endoscope negative pressure cleaning and sinupret drops to treat radiation nasosinusitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To observe the effect of nasal endoscope negative pressure cleaning and sinupret drops to treat radiation nasosinusitis (RNS).@*METHOD@#One hundred and fifty-three patients with nasopharyngeal carcinoma were randomly divided into treatment group A, B, C . Group A using nasal endoscope negative pressure cleaning and sinupret drops, group B using nasal endoscope negative pressure cleaning and normal saline spray washing, group C using saline nasal irrigation through nasal catheter. All patients with sinusitis condition were evaluated at the end of radiotherapy, three months and six months after radiotherapy.@*RESULT@#Comparison between groups, three periods of RNS incidence, moderate to severe RNS incidence are A < B < C. Six months after radiotherapy, group A compared with group C, there are significant difference (P < 0.01), group A and group C compared with group B respectively, the difference was statistically significant (P < 0.05).@*CONCLUSION@#Nasal endoscope negative pressure cleaning and sinupret drops can significantly reduce the long-term incidence of RNS, especially obviously reduce the incidence of moderate to severe RNS,which is a practical and effective method to treat RNS.

The combined application of dissociate skin flap and vacuum sealing drainage on the defect of the large neck neoplasms after surgical procedures / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the effect of the combined application of dissociate skin flap and vacuum sealing drainage (VSD) for the repairing for defect after surgical management of huge neck neoplasms.@*METHOD@#Nineteen patients with huge neck malignant tumor involving the skin of the neck were given radical operation, making use of VSD covering the wound surface. After giving 6.65-7.98 mm Hg continuous negative pressure drainage for 72 h, the patients turned to be treated by intermittent negative pressure therapy with 2 min free interval after each treatment period for 5 min. After dismantling the VSD at 7th to 10th day postoperatively, the good wounds covered by granulation tissue were treated by the skin graft operation with dissociate skin flap from thighs; as for the wounds of which the granulation tissue didn't grow well and important cervical tissues was not fully covered by the granulation tissue, VSD was applied again for 1 week, followed by the skin graft operation.@*RESULT@#Nineteen patients have received a total of 23 times of VSD wound treatment, one-stage operation time was significantly shortened. The granulation tissue grew faster on the wound after VSD treatment, and the important cervical tissues such as great vessels could be well covered. The infection and tumor recurrence were observed directly after dismantling the VSD. The skin graft transplantation would be performed after 1-3 weeks.@*CONCLUSION@#The treatment by vacuum sealing drainage combined with skin graft for surgical wounds of huge neck tumor postoperatively has the advantages of simple operation, little injury and promotion of the wound healing, which is an effective way for treatment of neck skin defect by surgical operation for the huge tumor.
