Some 7950 patients have been treated at the traditional medicine department of the Consulting and Diagnostic Center N52, 2/3rds of them came after long and unsuccessful medicamental treatment. Psychotherapy, manual therapy and acupuncture-reflex methods were successful in 86-93% of cases. They are recommended for local clinics provided that the latter are properly equipped and stuffed.  相似文献

The late latency components of visual evoked potentials (VEP) and the component P300 AEP were analyzed to evaluate their informative value in the process of mental function restoration in patient after long-term traumatic coma. VEP components with latencies of 70 to 320 msec were studied in 24 patients. Topographical mapping of the power of the study VEP components and components P300 was made by the peak amplitude. Long-term VEP components and component P300 were examined by the method of three-dimensional localization of equivalent dipole sources. In 16 patients with positive tendencies in the condition there was a stable localization of the maximum VEP power in the parietal, sagittal, and occipital regions, component P300 showed its maximum amplitude in the central and parietal regions in the left hemisphere. Eight patients with negative tendencies in the status had the maximum VEP and component P300 in the frontal and temporal regions, predominantly in the right hemisphere. The paper shows it important to evaluate not only time-amplitude parameters and analyzes the tomographic features of its formation in dynamics.  相似文献

15(2.4%) of 601 patients (392 have undergone transvesical adenomectomy, 111 had gunshot wound of the external genitalia and small pelvis organs, 98 had closed pelvic traumas, injuries of the urinary bladder and posterior urethra) were treated for persistent urinary fistulas with human allogenic fibroblasts growth cultures grown in the artificial medium. Before transplantation into the fistula tracts, the fibroblasts were grown in bioreactor on the microcarriers. Application of allogenic fibroblast growth culture has reduced hospital stay to 7.5 days. This method is simple and effective in inpatients. Use of allogenic fibroblasts allows to create bank of cell transplants for application in clinical practice.  相似文献

Replacement of the gall bladder with an isolated ileal segment was made to evaluate function of the urinary tracts depending on configuration of the created urine reservoir early and late after the operation in dogs. Intestinoplasty of the gall bladder changes parameters of ureteral function. Upper urinary tract urodynamics after ileocystoplasty is characterized by lowering of intraureteral pressure, decreased amplitude of the contractions, high tonicity and motility. The intestinal bladder has the same mean basal pressure at rest but less when full than the control animals. Reflex urination after the bladder reconstruction in subtotal resection was intact. Detubulized urinary reservoir had low intravesical pressure and no spontaneous contraction activity.  相似文献

Surgical treatment of late metastases of kidney cancer   总被引:1,自引:0,他引:1  
Whereas 25-57% of patients diagnosed with renal cell carcinoma (RCC) present with metastatic disease, about 50% of (RCC) patients develop metastases after potentially curative radical nephrectomy. Five-year survival at following surgical removal of solitary metastases is approximately 35-50%. Our experience demonstrate that a small cohort of patients benefit from aggressive surgical therapy for consequtively arising solitary distant metastases with long-term palliation.  相似文献

The effect of vertical banded gastroplasty (VBG) on the lipid profile in obese patients is considered. The antiatherogenic effect of VBG and of the following weight loss consists in significantly decreased plasma triglycerides, increased content of high-density lipoproteins and decreased atherogenic coefficient. Patients with hypercholesterolemia have significantly lower total plasma cholesterol by the period of the body mass stabilization. The effect of VBG is compared with that of other methods of correction of dyslipidemia. The possibility to improve this effect is also discussed.  相似文献

The article presents an analysis of immediate results of laparoscopic interventions (suturing, vagotomy) in 40 patients with perforated ulcers in the pylorobulbar zone. Postoperative complications were noted in 7.5% of the patients. There were no lethal outcomes. The authors recommend wider introduction of the laparoscopic technology as a method of optimization of surgical treatment for perforated ulcers.  相似文献

The authors share their experiences with treatment of wounds of the neck in 210 patients. Major vessels were injured in 85 of them (40.5%), arterial vessels being injured in 19 patients, venous vessels in 23 patients. 43 patients had wounds of the hollow, parenchymatous organs and nerves. All the patients with wounds of the hollow and parenchymatous organs recovered. Lethality among the patients with wounds of the major vessels was 11.9% and was due to a combination of injuries of the vessels and blood loss incompatible with life. Active surgical treatment of penetrating wounds of the neck with careful revision of the wound, use of emergency esophagogastroduodenoscopy, laryngotracheobronchoscopy, X-ray examination allow the amount of diagnostic errors and lethality to be reduced.  相似文献
