Objective To evaluate the clinical outcomes of external fixator with lumbopelvic distraction spondylodesis in treatment of vertically unstable pelvic fractures. Methods From January 2008 to March 2009, 9 patients (4 males and 5 females) with a vertically unstable pelvic fracture were treated with modular external fixator with lumbopelvic distraction spondylodesis. According to the classification of Tile, 9fractures were classified as type C. This fixation construct comprises a vertical lumbopelvic distraction component which fixed L4.5 and the posterior superior iliac spine and a transverse fixation which fixed anterior iliac spine with external fixator. Results All patients were followed up 12-18 months after surgery, with an average of 14.3 months. Postoperative X-ray showed satisfactory reduction of pelvic fracture. Pelvic fractures healed in all patients without loss of reduction 3-6 months after operation. According to Matta reduction evaluation criteria, 6 patients were excellent and 3 good. For the two patients with sacral neurological injuries,appropriate surgical decompression was performed to improve the symptom and minimize the deformity. No iatrogenic complications of neurovascular injury occurred. Patients now walk unassistedly without pain in the waist or legs, and with no shortening of lower limbs or claudication. By considering symptom and satisfactory scores, the Majeed functional assessment revealed that seven patients had excellent results and two good at one year. Conclusion External fixator with lumbopelvic distraction spondylodesis that allowed early mobilization and ambulation, with general applicability and definite safety, is an effective surgical technique for the treatment of vertically unstable pelvic fracture.

A 5-year-old Mongolian girl from Inner Mongolia presented with a painless,round skin lesion on the left cheek for 10 months.Several weeks prior to the development of lesions,her left cheek was seratched by a dog.Subsequently small asymptomatic erythematous papules developed at the scratched site and gradually enlarged.Direct microscopy of scales from the lesions revealed septate,branching hyphae and fungal culture grew Eurotiom amstelodami(perfect stage of aspergillus).She was initially diagnosed as cutaneous aspergillosis and treated with itraconazole 200 mg per day for 2 months,but limited improvement was achieved.Histopathological examination with Wright-Giemsa staining of skin biopsies revealed abundant leishman Donovani hodies intracellulatry and extracellularly in the dermis and subcutaneous tissue; PAS staining of tissue specimens showed no fungal element and fungal culture was negative.She was finally diagnosed with cutaneous leishmaniasis.After treatment with terbinafine 125 mg per day for 2 months,the lesion subsided.

Objective To investigate the effect and mechanism of low-dose remifentanil(RF)on systemic artery tension of baby rabbit with septic shock.Methods Thirty-six systemic artery strips were prepared from 12 baby rabbits and randomly divided into 6 groups:control group,lipopoly-saccharide(LPS)group,RF group,LPS + RF group,NG-nitro-L-arginine(L-NNA)pretreated group,LPS + L-NNA pretreated group.Each group had six rings(n =6).The effect of low-dose RF on the systemic artery tension of baby rabbit with septic shock was observed with isolated vascular ring technique.The change was also obversed after L-NNA pretreatment.Results In control group:the relaxant rates after low-dose RF at the time point of 5 min,10 min,20 min were(18.48±3.96)％,(23.63±4.42)％,(28.33±3.73)％(P＜0.05),compared with NS group.After pretreatment with L-NNA,RF-related relaxant rates of systemic arteries decreased significantly to(8.15 ± 1.01)％,(13.08 ± 1.46)％,(18.54 ±2.94)％(P ＜ 0.05).In LPS group,low dose RF(4 μg/L)did not bring out any response to systemic arteries(P ＞0.05).The tension was not affected with pretreatment of L-NNA(P ＞ 0.05).Conclusion These results suggest that low dose RF has relaxant effect on systemic arteries of baby rabbits,and NO may be involved.Low dose RF has no relaxant effect on LPS-pretreated systemic arteries of baby rabbits,and it has no association with NO.

Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

OBJECTIVETo analyze the clinical characteristics of elderly patients with spinal tuberculosis and explore its clinical effects with anti-TB drugs alone.

METHODSFrom January 2008 to July 2010, the data of 36 patients with spinal tuberculosis underwent conservative treatment of anti-TB drugs alone were analyzed. There were 19 males and 17 females with an average age of 73.5 years (ranged, 60 to 85). All patients were in the active phase with high ESR and CRP levels and were treated with 3HRZE/6-9HRE (course from 9 to 12 months). According to clinical symptoms, chemical examination, radiological image to adjust drug and depending on VAS score to evaluate pain.

RESULTSAll the patients were followed up from 8 to 24 months with an average of 15 months. Tuberculose of 31 patients healed after chemotherapy from 9 to 12 months and ESR and CRP recovered normally. Levofloxacin and para-amino salicylic acid were used in 4 cases because of 4 cases occurred drug fast for RFP or INH, after 15 months, their obtained healing. Symptom of 1 case got worse during chemotherapy, and surgical treatment were performed, after 3 months, ESR and CRP recovered normally, X-ray and CT showed spinal osteosclerosis and fusion without significant kyphosis and internal fixation loosening. Cobb angle was respectively(17.6+/-2.3) degrees, (18.1+/-2.7) degrees before treatment and last follow-up (P>0.05). MRI showed abscess was absorbed and spinal inflammation subsidised. VAS score was respectively 6.5+/-1.7, 1.4+/-0.5 before treatment and last follow-up (P<0.05). Seven patients had complications relating with drug adverse reaction,after discontinuation and treated with clinical symptom,the patients recovered normally.

CONCLUSIONAnti-TB drugs alone can obtain satisfactory effects in treating early senile spinal tuberculosis, but strict supervision and individual administration should not be disregardful.
