ABSTRACT

OBJECTIVE: To investigate the variation of pelvic radius and related parameters in low-grade isthmic lumbar spondylolisthesis. METHODS: Seventy-four patients with isthmic lumbar spondylolisthesis and 47 controls were included in this study. There were 17 males and 57 females between 30 and 66 years of age, including 30 with grade I slippages and 44 grade II slippages; diseased levels included 34 cases on L4 and 40 cases on L5. Thoracic kyphosis (TK), the pelvic radius (PR), the pelvic angle (PA), pelvic morphology (PR-S1), and total lumbopelvic lordosis (PR-T12) were assessed from radiographs. RESULTS: Statistically significant differences were found for the PA, PR-T12, and PR-S1 (24.5±6.6°, 83.7±9.8°, and 25.4±11.2°, respectively) of the patients with spondylolisthesis and the healthy volunteers (13.7±7.8°, 92.9±9.2°, and 40.7±8.9°, respectively). The TK/PR-T12 ratios were between 0.15 and 0.75. However, there were no differences in all the parameters between the L4 and L5 spondylolysis subgroups (p>0.05). The TK and PR-S1 of grade II were less than grade I, but the PA was greater. The PR-T12 of female patients were less than male patients, but the PA was greater (p<0.05). CONCLUSION: Pelvic morphology differed in patients with low-grade isthmic lumbar spondylolisthesis compared to controls. Gender and the grade of slippage impacted the sagittal configuration of the pelvis, but the segment of the vertebral slip did not. Overall, the spine of those with spondylolisthesis remains able to maintain sagittal balance despite abnormal pelvic morphology.

ABSTRACT

Objective To observe the dynamic serological test results of 28 patients with acute brucellosis,and to investigate the relationship between serological test results and diagnosis,curative effect and prognosis of brucellosis.Methods Twenty eight patients(infected with sheep brucellosis) with acute brucellosis in the Department of Brucellosis in Heilongjiang Provincial Land Reclamation Headquarters General Hospital were selected as research subjects,and their serological changes were tested by means of tube agglutination test (SAT)and clinical outcomes were compared before and after each stage of treatment.In addition,symptoms of fever,weakness,sweating,joint pain,swollen lymph nodes and biochemical parameters [alanine aminotransferase (ALT),lactate dehydrogenase (LDH)] were also tested 3,6 and 9 weeks after the treatment.Results Antibody titer reached the peak at the third week,1 ∶ 400(++),which accounted for 39.29% (11/28); 2857%(8/28) of the patients became negative at the sixth week; 50.00% (14/28) became negative at the ninth week.Before the treatment,20(71.43%) patients had the symptom of fever,8 (28.57%) patients had the symptom of hyperhidrosis,28 (100.00%) patients had the symptom of joint pain,7(25.00%) patients had the symptom of lymph node enlargement,28 (100.00%) patients' ALT was elevated,and 26(92.86%) patients' LDH was elevated.After three weeks of treatment,except the three patients (10.71%) who occasionally had fever,the rest of the patient's temperature was returned to normal.Also the numbers of patients with the symptoms of fatigue,sweating and joint pain were significantly reduced,and specifically,the conesponding number was 13(46.43%),2(7.14%),and 21 (75.00%)patients,respectively.ALT and LDH returned to normal(only one patient's ALT was out of the range).At the sixth week,all the patients' symptoms of fever and hyperhidrosis disappeared.The number of patients with the symptoms of joint pain and lymph node enlargement reduced to 12(42.86%) and 3(10.71%),respectively.The results of biochemical tests(ALT and LDT) returned to normal.At the ninth week,most patients' clinical symptoms disappeared.A few patients still had the symptoms of weakness[2(7.14%)] and joint piin[6(21.43%)].Conclusions After effective treatment,antibody titer of patients decreases rapidly,at the same time,the clinical symptoms improve quickly.There is a parallel relationship between the change of antibody titer and clinical symptoms.It is demonstrated that the appearing time of brucellosis specific antibodies,the ampfitude and speed of change of antibody titers can be used in diagnosis,therapeutic evaluation and prognosis of the disease.

ABSTRACT

Objective To observe the clinical features of brucellosis spondylitis and analyse the reasons for its misdiagnosis,and improve the level of diagnosis and differential diagnosis.Methods Forty-two clinically diagnosed patients with brucellosis spondylitis were studied retrospectively,and these patients were diagnosed and hospitalized in the General Hospital of Heilongjiang Land Reclamation Bureau.Their medical records were analyzed,which included the general information,medical history,clinical symptoms,results of magnetic resonance imaging(MRI) and serum tube agglutination test(SAT) and so on.Results Main clinical symptoms and signs were severe persistent neck,back and leg pain.They also had plate shape low back but without kyphosis.In addition,patients had to keep in one posture because their spinal activity was limited.Also,scoliosis or pelvic tilt and lameness may occur when standing,which were typical symptoms of nerve root compression.Thirteen cases were diagnosed as tuberculosis,accounting for 30.95%(13/42); 6 cases were diagnosed as lumbar disc herniation,accounting for 14.28% (6/42); 2 cases were diagnosed as ankylosing spondylitis,accounting for 4.76% (2/42).Therefore,the total rate of misdiagnosis was 50% (21/42).Abnormal MRI signal intensity can be seen in the pathological vertebrae.Specifically,T1-weighted images (T1WI) showed low signal,T2-weighted images (T2WI) showed high signal,or mixed high and low signal intensity was observed.Vertebral showed wedge deformation without collapse and sequestrum; strip and sheet abnormal signal can also be found within the intervertebral disc.Normal structure disappeared and disc space became narrow.Accordingly,the plane dural sac was compressed to form visible abscess near the spine,but psoas abscess was not found.Patients with positive SAT result accounted for 92.85% (39/42).Conclusion Reasons for misdiagnosis include lack of detailed medical records,atypical clinical symptoms and similar imaging changes and so on.

ABSTRACT

Measurement of platelet-associated imunoglobulin (PAIg) has frequently been applied for the diagnosis of idiopathic thrombocytopenic purpura (ITP) and other immune thrombocytopenias. In the present study, a flow cytometry (FCM) analysis has been used to detect and characterize PAIg in 47 patients with ITP and Evans' syndrome, 13 patients with non-immune thrombocytopenia, 10 patients with autoimmune hemolytic anemia (AIHA) whose platelet counts were in normal range, and 31 healthy volunteers. With FCM measurement, mean fluorescence intensity (MFI) of platelets from patients with ITP and Evans' syndrome (2.26 +/- 2.29) was significantly higher than those from non-immune thrombocytopenia (0.33 +/- 0.39), AIHA (0.17 +/- 0.07) and control subjects (0.25 +/- 0.15) (P < 0.01). Meanwhile, the percentage of positive platelets of patients with ITP and Evans' syndrome [(44.1 +/- 29.0)%] was also higher than those of non-immune thrombocytopenia [(17.5 +/- 9.4)%], AIHA [(10.7 +/- 7.5)%] and control subjects [(16.6 +/- 8.4)%] (P < 0.01). In addition, some peak shape abnormality appeared (double peaks and peak tail) in the histogram of fluorescence intensity (log) of 11 patients (23.4%) with ITP and Evans' syndrome either alone or accompanied with quantitative alteration of MFI and/or positive platelet percentage. In seven cases, the peak shape abnormality was the unique characteristic that could be detected and have never been seen in normal platelets. This phenotypic alteration perhaps reflects the existence of different platelet populations and could be of diagnostic value. Totally, the positive result of FCM measurement in patients with ITP and Evans' syndrome was 87.2%, slightly higher than 83.0% positive rate with ELISA method, without statistical difference. The correspondent rate of the results of these two analytical settings was 85.1%. This study shows that FCM assay is a rapid and sensitive method for the measurement of PAIg and seems to be suitable as a novel routine diagnostic technique of immune thrombocytopenia.
