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.

Objective To evaluate abdominal imaging in AIDS.Methods The imaging examinations(including US,CT and MR)of 6 patients with AIDS associated abdominal foci were analysed retrospectively.All the cases were performed US,and CT scan,of which 4 performed enhanced CT scan and 1 with MR.Results Abdominal tuberculosis were found in 4 patients,including abdominal lymph nodes tuberculosis(3 cases)and pancreatic tuberculosis(1 case).The imaging of lymph nodes tuberculosis typically showed enlarged peripheral rim enhancement with central low-attenuation on contrast-enhanced CT. Pancreatic tuberculosis demonstrated low-attenuation area in pancreatic head and slightly peripheral enhancement.Disseminated Kaposi's sarcoma was seen in 1 case:CT and MRI scan demonstrated tumour infiltrated along hepatic portal vein and bronchovascular bundles.Pelvic tumor was observed in 1 case:CT scan showed large mass with thick and irregular wall and central low attenuation liquefacient necrotic area in the pelvic cavity.Conclusion The imaging findings of AIDS with abdominal foci is extraordinarily helpful to the diagnosis of such disease.Tissue biopsy is needed to confirm the diagnosis.

BACKGROUND:Pedicle screw is the major instrumentation of surgery in thoracic spine. However, there have been few reports about pedicle morphology relevant to screw insertion tracts, and few reports comparing the normal adolescents and adolescent idiopathic scoliosis patients. OBJECTIVE:To compare the morphologic characteristics of the thoracic pedicle with regard to safe thoracic pedicle screw placement in normal adolescents and adolescent idiopathic scoliosis patients. METHODS: Thoracic pedicles of thirty-five normal adolescents and thirty-five adolescent idiopathic scoliosis patients were measured with three-dimensional reconstruction CT images. Measured parameters include (1) critical distance: the shortest distance from an entry point to the ventral cortex of the lamina. (2) Safe distance: the distance from the entry point to the tangent of the spinal canal at the medial wal of the pedicle. (3) Pedicle screw length. (4) Pedicle width. (5) Pedicle transverse angle. The dangerous area was defined as the distance between the critical distance and the safe distance. RESULTS AND CONCLUSION: The mean critical distance was (9.2±1.0) mm for the normal adolescents, and (9.4±1.2) mm for the adolescent idiopathic scoliosis patients. Safe distances were significantly less in normal adolescents (14.7±0.8) mm than that of the adolescent idiopathic scoliosis group (15.4±1.4) mm (P < 0.001). The dangerous area was (5.4±0.7) mm for the normal adolescents, which was significantly less than that of the adolescent idiopathic scoliosis patients (6.0±1.0) mm (P < 0.001). Pedicle screw length was (36.6±4.1) mm for the normal adolescents and (37.1±5.3) mm for the adolescent idiopathic scoliosis patients. Pedicle width was (5.8±1.2) mm for the normal adolescents and (5.7±1.7) mm for the adolescent idiopathic scoliosis patients. No significant difference in critical distance, pedicle screw length and pedicle width was found between the two groups (P=0.382, 0.135, 0.293). Pedicle transverse angle decreased gradualy from T1 to T12 in both groups. These results verify that pedicle morphology of many parameters is different between normal adolescents and adolescent idiopathic scoliosis patients, especialy in the apical area of the thoracic curve.

Objective To evaluate X-ray,CT and MRI findings of soft tissue infections in AIDS. Methods Three cases of soft tissue infections with AIDS were retrospectively analyzed by comparing the imaging findings with pathological results.All patients were performed MRI,X-ray was in 1 case,CT was in 1 case.Results Cellulitis was in 1 case:MRI showed extended thickening of subcutaneous tissues, ill-defined hypointense areas on T_1WI and hyperintensity on T_2WI,and reticular pattern on GRE. Necrotizing fasciitis was in 1 case:MRI showed obvious thickening of subcutaneous tissues and deep fasciae, abnormally increased signal intensity on T_1 and T_2WI.Fluid collections were within muscles and muscles interval on fat-suppressed T2 WI.Tuberculosis was in 1 case:CT demonstrated multiple low density areas in the subcutaneous tissues and clear peripheral rim enhancement.MRI appeared hypointense on T_1WI and hyperintensity on T_2WI,and peripheral rim enhancement following gadolinium injection.Conclusion Infections of soft tissue are common complication in patients with AIDS,radiology is important in early diagnosis and treatment planning in this population.

Objective To report a three-generation Chinese family with freckle and to make a genetic linkage analysis in this family.MethodsGenetic linkage analysis was carried out in this family using microsatellite markers distributed over chromosome 4q and 1.Two-point logarithm of odds(LOD)scores were calculated using the Linkage program package(version 5.1),and haplotype was analyzed with Cyrillic version 2.01 software.Results Freckle was inherited in an autosomal dominant pattern with a penetrance of99.9% in this family;linkage to chromosome 4q was ruled out however,supportive evidence was obtained for linkage to microsatellite markers D1S2635 and D1S2844 in chromosome 1q with a maximum LOD score of 1.50.Haplotype analysis in this family localized the locus of freckle to a 12 Mb region flanked by D1S2624 and D1S2799.Conclusions Freckle is a genetically heterogeneous disorder.The causative gene may be located in a 21.2 cM region on chromosome 1q22-24.

OBJECTIVETo determine how selected gait parameters may change as a result of total hip arthroplasty (THA).

METHODSFrom February 2006 to February 2007 the study was performed on 53 osteonecrosis of femoral head subjects prior to and 6 weeks, 3, 6 and 12 months after total hip arthroplasty surgery. Gait analysis was performed using the three-dimensional Infrared-based system (Dalian Dong Fang Xin Rui Company, China). Kinematic data were recorded for the lower limb. The results obtained from the osteonecrosis of femoral head subjects were compared with those of 40 individuals without osteonecrosis. Using a three-dimensional motion analyzer, the following were measured: (1) gait speed, stride length, cadence; (2) step length, stride width; (3) standing phase time, walking phase time; (4) gait cycle time, Joint movement angular.

RESULTSCompared with persons before total hip arthroplasty, THA patients showed significantly increased gait speed, gait frequency, step length and affected limb stand phase (P < 0.01). Angle timetable: preoperative hip-maximum flexion was 15 degrees, post-extension was 8 degrees, knee-maximum flexion was 70 degrees, ankle-maximum flexion was 15 degrees. Postop hip-maximum flexion was 27, post-extension was 17 degrees, knee-maximum flexion was 50 degrees, ankle-maximum flexion was 14 degrees; parameters of hip, knee between preoperative and postoperative was significance (P < 0.01).

CONCLUSIONThese results suggest that 3-D gait analysis before and after total hip arthroplasty can evaluate precisely hip vitodynamics variation.

Serum cortisol and plasma ACTH were determined in 10 patients with severe sepsis and 12 with septic shock on day 1,3,5 after diagnosis were made,and the data were compared with 12 control patients. To evaluate the hypothalamic-pituitary-adrenal(HPA)axis function in patients with severe sepsis and septic shock,1?g ACTH stimulation test was applied after hormone concentrations were obtained on day 1.Compared with the control patients,ACTH level was significantly higher in patients with severe sepsis and lower in septic shock(P

OBJECTIVETo investigate the effect of preoperative use of viable Bifidobacterium supplement on the intestinal flora, immune status, inflammatory response and prognosis of patients undergoing colorectal cancer resection.

METHODSSixty patients with colorectal cancer were randomized into treatment group (n=30) and control group (n=30). Patients in the treatment group received oral viable Bifidobacterium with routine enteral nutrition and patients in the control group received routine enteral nutrition alone. The intestinal flora of stool was analyzed and stool SIgA, serum IgG, IgM, IgA, IL-6, and C-reactive protein (CRP) were detected.

RESULTSPostoperative Bifidobacterium/E.coli (B/E) ratio in the treatment group decreased significantly as compared to the preoperative ratio (2.01+/-0.36 vs 26.53+/-4.22, P<0.05). However, the ratios remained above one. Both preoperative and postoperative B/E ratios in the control group (0.72+/-0.14, 0.02+/-0.06) were significantly lower than those in the treatment group (P<0.05). Indexes of immunity and inflammation were not significantly different between the two groups (P>0.05). At day 9 after operation, stool SIgA was higher in the treatment group, while serum IgG, IgM, IgA, IL-6, CRP in the treatment group were lower (P<0.05). Postoperative septic complications in the treatment group was less than that in the control group (P<0.05), but other complications and hospital stay were comparable.

CONCLUSIONSIn patients with colorectal cancer, supplementation of viable Bifidobacterium before surgery can improve bacterial dysbiosis and immunity, and can reconstruct the balance of intestinal flora, and reduce infection complication of surgery.
