RESUMO
OBJECTIVE To investigate the application value of combined detection of fecal pathogens in infantile diarrhea.METHODS The Escherichia coli was detected by potato-dextrose agar(PDA) medium method and serum agglutination test was used to determine the serotype.The rotavirus,enteric adenovirus and Campylobacter jejuni were detected with latex agglutination test antigens.RESULTS Among the diarrhea children,the detection rate of rotavirus,C.jejuni to their,E.coli 1.5%,and adenovirus was 33.0%,7.2%,1.5% and 0.7%,respectively.The proportion of male and female detected positive was 1.6∶1.CONCLUSIONS The main etiologies of infantile infectious diarrhea are rotavirus and C.jejuni.The infection rate of E.coli and enteric adenovirus is lower.Therefore,combined detection of pathogens causing diarrhea is valuable to diagnose the infantile diarrhea.
RESUMO
BACKGROUND: The most dangerous consequence of thoracolumbar burst fracture is its neurological deficits(caused by primary and/or secondary injury) . It is reported that posterior spinal decompression combined with internal fixation are viable in reduction of fracture and indirect decompression of obstructed spinal canal.OBJECTIVE: To evaluate the effect of anterior decompression combined with STRYKER thoracoluambar anterior internal fixation system in improving spinal canal stenosis and spinal mechanical axis in thoracolumbar burst fracture.DESIGN:It is a case report.SETTING:An orthopedic department of a municipal hospital.PARTICIPANTS:In this study, five patients (four male, one female, aged 17 - 34 years) were recruited who suffered from thoracolumbar burst fracture and spinal cord dysfunction and were treated in the Orthopaedic Departnent of Dongguan Taiping People' s Hospital from September 2001 to February 2002.METHODS: All patients received anterior decompression and intervertebral grafting with iliac or rib bone flap combined with reduction and internal fixation by STRYKER system. X-rays of thoracolumbar vertebrae were taken in the 1st, 3rd, 5th and 9th post-operative months for observation of fusion of injured segments, improvement of narrowed spinal canal and kyphosis angle. And Frankel scale was adopted for evaluation of the patients during follow-up(A for bad and E for excellent).narrowed spinal canal.RESULTS: All of the 5 patients entered analytic stage and follow-up lasted grade B in one patient, all the others got Frankel grade E and could walk gical operation was 68.9% and after operation there was no spinal canal tion to 0° - 6° afterward.CONCLUSION: Anterior spinal decompression can directly and completely provide satisfactory environment for the recovery of neurological of deficits spinal cord. STRYKER thoracoluambar anterior internal fixation system applied in patients with thoracolumbar burst fracture and paraplegia can effectively restore normal spinal curve with the advantages of simple procedure and stable fixation as well as the characteristics of biological internal fixation such as satisfactory reduction and stable fixation.
RESUMO
Objective To evaluate the experience of replantation of severed finger tip and suggest a new method to replant the severed finger tip injury. Methods A total 25 cases of severed finger tip injuries on nail root level were retrospectively analysed.They were 18 males and 7 females,19～38 years old.The finger tips were completely cut down.The wound should be cleaned thoroughly under operative microscope and the cut ends of artery and nerve can be found on the wound.The important step was to dissect out all braches of the arch of the artery and ligate them but one small branch,so as to reduce the blood circulate into the finger tip.It was not necessary to joint the vein. Results Twenty-four fingers were survived,only one finger was necrosed.The course of 13 fingers were very prosperous.Twelve fingers had some cyanosis and 9 fingers turned red after a few punctures to release the venous blood and other 3 fingers should make a side incision torelease more venous blood.Then 2 fingers were survived and one finger was failured. Conclusion Only one artery should be anastomos for finger tip injury on nailroot level.No vein should be joint.But the branches of the artery arch should be ligated except one small branch.
