ObjectiveTo introduce the application of Photoshop CS16.0 (PS) software in preoperative osteotomy design of ankylosing spondylitis kyphosis (ASK), and to investigate applied values of the preoperative design. MethodsBetween March 2009 and March 2013, 21 cases of ASK were treated through preoperative osteotomy design by using PS software. There were 16 males and 5 females, aged from 23 to 50 years (mean, 34.2 years). The deformity included thoracolumbar kyphosis in 14 cases, thoracic kyphosis in 2 cases, and lumbar kyphosis in 5 cases. The ultimate osteotomy angle of preoperative plans and the location and extent of osteotomy were determined by the osteotomy design, which guided operation procedures of the surgeon. The actual osteotomy angle was obtained by measuring Cobb angle of osteotomy segment before and after operation. The sagittal parameters of spine and pelvis including global kyphosis (GK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), and chin brow-vertical angle (CBVA) were measured at preoperation, at 1 week after operation, and last follow-up. The clinical outcomes were assessed by simplified Chinese Scoliosis Research Society-22 (SRS-22) questionnaire and Oswestry disability index (ODI). ResultsNo complications occurred in the other cases except 1 case of dural tear during operation and 1 case of nerve injury after operation, and primary healing of incision was obtained. All patients were followed up 14 to 45 months (mean, 26.3 months). The SRS-22 and ODI scores at 1 week after operation and last follow-up were significantly improved when compared with preoperative scores (P<0.05), but no significant difference was found between at 1 week and last follow-up (P>0.05). The preoperative planned osteotomy angle and the postoperative actual osteotomy angle were (34.2±10.5)° and (33.7±9.7)° respectively, showing no significant difference (t=0.84, P=0.42). The CBVA, GK, SVA, PT, and LL were significantly improved when compared with the preoperative values (P<0.05), but no significant difference was found between at 1 week and last follow-up (P>0.05). At last follow-up, no failures of internal fixation was found, and bony fusion was obtained. ConclusionThe preoperative osteotomy design by using PS software can precisely recover the spinal sagittal balance and horizontal angle of view, so it can effectively avoid excessive correction and insufficient correction of the deformity and obtain good effectiveness in treating ASK.
So far, there have been several kinds of valvuloplasty techniques for Ebstein's anomaly. Cone reconstruction which was developed by Da Silver and his coworkers has attracted much attention from worldwide cardiac surgeons. Because this technique could reconstruct the leaflet to leaflet coapatation which permits central blood flow during diastole period. It is probably the most efficient anatomical correction method. We make a comprehensive literature retrieval concerning the Cone reconstruction for Ebstein's anomaly. Its development, key points of technique skills and prognosis evaluation are reviewed meticulously.
Objective To evaluate the clinical effectiveness of the first metatarsophalangeal (MTP) joint arthroplasty versus arthrodesis for rheumatoid forefoot deformity. Methods The randomized controlled trials (RCTs) about the first MTP joint arthroplasty vs. arthrodesis for rheumatoid forefoot deformity published by February 2012 were searched in the databases such as CNKI, Ovid, MEDLINE, CBM, EMbase, WanFang Data, The Cochrane Library (Issue 1, 2012), and KJEBM. Two reviewers independently screened studies, extracted data, and evaluated the methodological quality according to the inclusion and exclusion criteria. Then meta-analysis was conducted using RevMan 5.1 software. Results A total of 4 RCTs were included. Among total 206 (269 feet) patients involved in, 98 (130 feet) were in the arthroplasty group, while the other 108 (139 feet) were in the arthrodesis group. The results of meta-analysis showed that the arthrodesis group was superior to the arthroplasty group in the footwear (MD=−0.88, 95%CI −1.55 to −0.22, P=0.01), and the alignment (MD=−5.04, 95%CI −8.94 to −1.14, Plt;0.000 01) with significant differences. But there were no significant differences between the two groups in patient satisfaction, metastatic lesions, pain, activity and weight-bearing of Hallux. Conclusion Based on the current studies, arthrodesis is superior to arthroplasty in treating rheumatoid forefoot deformity. For the quality restrictions and possible publication bias of the included studies, more double blind, high quality RCTs are required to further evaluate the effects.
Objective To define an evidence-based conclusion concerning ultrasound screening for fetal genital system malformations during pregnancy. Methods In order to assess whether or not ultrasound screening for fetal genital system malformations is effective and feasible, we searched The Cochrane Library (Issue 3, 2009), MEDLINE (1981 to 2009), ACP Journal Club (1991 to 2008), and BMJ Clinical Evidence (1999 to 2008) for systematic reviews, randomized controlled trials (RCTs), cohort studies, and controlled clinical trials. Results Five cohort studies and three crosssectional studies were retrieved. The results showed ultrasound screening detected fetal sex determination by the contour of the rump and the angle of the genital tubercle to a horizontal line through the lumbosacral skin surface in the first trimester. Scrotal size and penile length increases with gestational age for male fetuses, and by 32 weeks, bilateral testicular descent was observed in most cases. Ultrasonographic scans, fetal genetic studies, and hormonal assays of amniotic fluid can diagnosis certain diseases, fetal sex differentiation disorders, fetal endocrinal disorders, and chromosome abnormality. Conclusion The findings of this study should reassure physicians and parents alike that ultrasound screening is an reliable option for the prenatal diagnosis of fetal genital system malformations, but more randomized controlled trials are needed to further supply relevant evidence.

Objective To explore the clinical presentation and diagnosis and treatment of prehepatic portal hypertension （PPH） and discuss its surgical strategies. Methods Forty-six cases of PPH treated in the 2nd Artillery General Hospital and Peking Union Medical College Hospital from January 2000 to May 2009 were analyzed retrospectively, including 2 cases of Abernethy abnormality. All patients were evaluated by indirect portal vein angiography, CT angiography and (or) portal duplex system Doppler ultrasonography before treament. Surgical strategies included: 23 cases with meso-caval shunt, 8 cases with splenectomy and spleno-renal vein shunt, 1 case with porta-caval shunt, 2 cases with paraumbilical vein-jugular vein shunt, 3 cases with portal azygous disconnection, 1 cases with splenectomy and portal azygous disconnection, 1 case with sigmoidostomy and closed the fistula of sigmoid six months later, 1 case with resection of part of small intestine due to acute extensive thrombosis of portal vein system, 4 cases with selective superior mesenteric artery and (or) splenic artery thrombolytic infusion therapy, 2 cases remained no-surgical option and underwent conservative treatment. Results Forty-four patients were followed-up from 2 months to 5 years， average of 23.4 months, one patient without surgical treatment was lost. Satisfactory outcomes were obtained in 34 patients with various shunts, which expressed as a release of hypersplenism and gastrointestinal hemorrhage. Two cases were treated with meso-caval shunt because of rehemorrhage in month 13 and 24 and one died in month 8 after disconnection, one died on day 40 after thrombolytic therapy due to putrescence of intestines, one who remained no-surgical option underwent hemorrhage 4 months later, and then went well by conservative treatment. Conclusion The key of treatment of PPH is to reduce the pressure of hepatic portal vein. Surgical managements of shunt and selective superior mesenteric artery and (or) splenic artery thrombolytic infusion therapy are safe and effective, but individual treatment strategy should be performed.
