Objective To investigate the radiological characteristics and the relationships between the parameters by X?ray and direct magnetic resonance arthrography (dMRA) in non?completely dislocated dysplasia hips. Methods We retro?spectively reviewed patients (above 13 years old) with dysplasia hips from August 2009 to August 2012. These patients were classi?fied as Hartofilakidis typeⅠand typeⅡ. 188 patients (274 hips) involved 28 males (30 hips) and 160 females (244 hips), average aged 27.3 years (range 13-47 years). Standard pelvic A?P, bilateral 65° oblique X?rays, and dMRA were conducted in each pa?tient. Lateral central?edge angle (LCE), anterior central?edge angle (ACE), femoral neck?shaft angle (FNSA), and tonnis acetabu?lar index (AI) angle were measured based on the X?ray. The dysplasia hips were classified into 4 grades (GradeⅠ:CE 11°-20° , GradeⅡ:CE 1°-10°, GradeⅢ:CE-9°-0°, and GradeⅣ:CE≤-10°). Femoral neck anteversion angle (FNA), labral tear, labral inversion, and labral cyst was observed on dMRA films. Variance analysis and rank correlation were applied to find the relation?ship between CE grades and the relevant parameters by using SPSS 19.0. Results LCE has negative correlation with AI and grade of osteoarthritis, and has positive correlation with age, ACE. However, there was no relationship between FNSA and FNA. There was significantly different in Shenton's line, labral tear, labral inversion, cartilage lesion, among different grade of LCE. Conclusion LCE is an important parameter used in evaluating for dysplasia hips without complete dislocation. LCE can reflect age of onset, ACE, AI angle and degree of joint damages. Evaluation for the severity of non?completely dislocated dysplasia hips can be conducted according to grades of CE.

Objective To introduce a case of varicella.zoster virus(VZV)-related glomerulonephritis and encephalitis. Methods The clinical data and renal pathology were analyzed.Associated literatures were reviewed. Results A 15 years old male patient presented nephritic syndrome,nephrotic syndrome and renal dysfunction with reduced serum complement C3 level from the 5th day after he suffered from varicella.The pathological diagnosis of his kidney tissue was endocapillary proliferative glomerulonephritis with podocyte proliferation and severe renal tubular injury by light microscopy.Immunofluorescent and electron microscopic examinations showed "full-house"staining and granular electron-dense deposits in multiple sites.respectively. Furthermore.virus-like particles or/and inclusions could also be seen by electron microscopy and Mann staining light microscopy.Positive varicella-zoster virus (VZV) specific lgM antibody was detected by serum virological test.VZV antigen and RNA transcript were found in glomerular and tubular cells by immunohistochemical staining and in situ hybridization of renal tissues,respectively. The patient had epileptic episodes for many times in his disease course and his brain MRI and electroencephalogram findings accorded with viml encephalitis with secondary epilepsy.So,the diagnosis of VZV-related glomerulonephritis and encephalitis was established. Conclusion This is the first report of VZV-related glomerulonephritis and encephalitis confirmed by serum virology and tissue virology.

Objective To discuss the mid?to long?term results and possible prognostic factors of Bernese periacetabu?lar osteotomy for adolescents and young adults with developmental dysplasia of the hip. Methods Bernese periacetabular os?teotomy was performed on 162 patients (171 hips) with hip dysplasia from August 1997 to July 2009. Follow?up data was ac?quirable completely in 123 cases (137 hips), including 30 males (33 hips) and 93 females (104 hips). Age of surgery was 12-48 years (average 27.1 years). The X?ray radiographs and Harris scores were recorded preoperatively and at the last follow?up. The lateral center?edge angle (LCE), acetabular incline angle (AI), continuity of Shenton's line were also recorded. The grades of the hip osteoarthritis were classified by T?nnis classification. Insufficient corrections of osteotomy, excessive corrections of osteotomy, nonunion of the pubis, nerve injuries, and vascular injuries were recorded as complications. Results All the con?tactable cases was followed up again in June and July in 2014. Follow?up duration was 5-17 years (mean, 8.1 years). The LCE angle improved from 7.13° ± 8.86° preoperatively to 30.17° ± 14.98° at the final follow?up. The T?nnis acetabular incline angle decreased from 27.84° ± 12.85° preoperatively to 7.06° ± 10.58° at the final follow?up. The continuity of Shenton's line was in?tact in 106 cases postoperatively, compared with 87 cases preoperatively. Harris score improved from 83.34±9.82 preoperative?ly to 92.79±7.05 at the last follow?up. There was significant correlation between preoperative Harris score and Harris score at the last follow?up. Early complications were observed in 15 cases (15 hips), along with 17 cases (17 hips) of progressions of hip osteoarthritis. Survival rate of the hip at the last follow?up was 97.8%. Conclusion Bernese periacetabular osteotomies can significantly improve bone coverage and joint function of hip dysplasia patients with low rate of short?term complications. Further?more, there was little osteoarthritis progression observed, with good survival rate of the joint in mid?to long?term follow?up. Lower pre?operative Harris scores and higher pre?operative T?nnis classifications are important prognostic factors for post?operative pain.
