ABSTRACT
OBJECTIVE: To investigate the risk factors of venous thrombosis(VTE) and to evaluate the predictive ability of the existing risk assessment models(RAM) in medical oncology inpatients. METHODS: In this study, 252 medical oncology inpatients were divided into study group(63) and control group(189) according to VTE. Logistic regression analysis was performed to identify the risk factors of VTE and to evaluate the predictive ability of KRS and PPS. RESULTS: This study showed that previous VTE, staying in bed≥3 d,platelet count≥350×10~9/L, D-dimer>0.55 mg/L and stage IV cancer were associated with VTE risks(OR=12.149, 3.672, 3.144, 5.263,1.439, 1.382, P0.55 mg/L, and stage IV cancer are independent risk factors of VTE. Compared with the limited predictive ability of PPS,KRS can predict VTE very well for low-and intermediate-risk patients.
ABSTRACT
As one of the common type of ocular injuries,orbital fracture can result in enophthalmos,diplopia and infraorbital nerve injury,which affects the physiological function of eyeball.Repairing surgery for orbital fracture should be treated for reconstructing the orbital anatomical structure in case of severe enophthalmos and diplopia,or infraorbital nerve injury.Meanwhile,it's crucial to identify the suitable surgery approach and implants because of the specificity and complexity of the orbit.What a clinician expected most is the ideal prognosis obtained easily with minimal operation complication.Transconjunctival approach should be applied as one of the standard approaches for repairing surgery of orbital fracture,offering good operative field with less complications.Titanium mesh and resorbable materials are the ideal implants at present,for their high level of stable quality and plasticity.More and more applications of 3D-printed rapid prototyping technique can guide the new directions of individualization and precision of repairing surgery for orbital fracture.
ABSTRACT
Abstract?AlM:To evaluate the accuracy and practicability of three - dimensionally preformed Arbeitsgemeinschaft Osteosynthese AO titanium mesh plates for orbital fractures.?METHODS:Forty-seven patients with isolated blow-out orbital fractures were included in this study. Fracture locations were as follows: floor/medial wall ( n = 26, 55%), medial wall ( n = 12, 26%), and floor ( n = 9, 19%) . The floor fractures were exposed by a standard transconjunctival approach, whereas a combined transcaruncular transconjunctival approach was used in patients with medial wall fractures with temporary dissection of inferior oblique muscle. A three -dimensionally preformed AO titanium mesh plate was selected according to the size of the defect previously measured on the preoperative computed tomographic scan examination and fixed at the inferior orbital rim with 2 screws. The accuracy of plate positioning of the reconstructed orbit was assessed on the postoperative computed tomography ( CT) scan. The practicability of clinical use of AO three - dimensionally preformed titanium mesh plates was assessed on the preoperative and postoperative clinical data.?RESULTS: Postoperative orbital CT scan showed an anatomic three- dimensional placement of the orbital mesh plates in all of the patients. All patients had a successful treatment outcome without clinical complications. 40 patients ( 87%) had a successful enophthalmos correction. 25 patients ( 86%) had a successful recovery from diplopia.?CONCLUSlON: Three- dimensionally preformed AO titanium mesh plates for orbital fracture reconstruction results in an accurate anatomic restoration of the bony orbital contour with a high rate of success to correctenophthalmos and diplopia.
