The research goal is to state possibility of virtual colonoscopy and to determine the localization and nature of neoplasms in the large intestine. Materials and methods: 38 patients have been examined by the methodof virtual colonoscopy. The preceding stage of diagnosis by total ibrocolonoscopy has not been a success. Results: Virtual colonoscopy has been performed in 94.7 % ofpatients. The same tumors have been identiied in the proximal colon, direct examination of which has not been possible. Conclusion: Virtual colonoscopy is the methodof choice for topical diagnosis of tumors of the colon.
Ingrown toenail is a clinical condition that progresses with pain, redness, swelling, granulation tissue and purulent drainage due to the growth of an edge of the toenail into the skin of the toe . Although it is considered to be a simple discomfort, the fact that it is a frequent condition which causes workforce loss and afects daily life negatively increases its signiicance. The reasons for ingrown toenail are mistrimming of the nail, wear- ing tight shoes, standing for long periods of time and genetic predisposition . Because of these risk factors, the nail grows into the skin of the toe and edema and redness appear on the sot tissue. This in turn causes disruption of the integrity of the skin and infection. The infection that is formed drains on the one hand and tries to limit with granulation tissue on the other hand. Thus, a vicious circle forms. While medical treatment is preferred for mild cases, surgical treatments are recommended for advanced cases. Although there are many treatment meth- ods, new treatments are being tried every day because of loss of workforce and frequency of recurrence. This study examines the methods of partial nail removal and percutaneous matricec- tomy for ingrown toenail.
We present a protocol to test a newsurgical procedure for the treatmentofpatientswith diffuse lung emphysema who, after having received the golden standard treatment (pulmonary rehabilitation), continue to present respiratory failure with disabling dyspnea. Ten patientswith severe lung hyperinflation will be evaluated. The method proposed is designed to create alternative expiratory passages for air trapped in the emphysematous lung by draining the lung parenchyma, thereby establishing communication between the alveoli and the external environment. The ten patients selected will be required to meet the inclusion criteria and to give written informed consent. Those ten patients will be included in the study pending the approval of the Ethics in Research Committee of the São Paulo Santa Casa School of Medicine, São Paulo, Brazil. The protocol we will employ in order to evaluate the proposed procedure is feasible and will show whether debilitated patients suffering from diffuse pulmonary emphysema can benefit from this procedure, which could represent an alternative to lung transplant or lung volume reduction surgery, the only options currently available.

condition for many years, undergoing the surgical procedure in adulthood, and, in some cases, at an advanced age, certainly because they had been unaware of the fact that there is a simple, effective, and widely accepted treatment: video-assisted thoracic sympathectomy. This minimally invasive technique, developed in the late 1980s, came to be more widely employed and disseminated in scientific studies, as well as in the lay press, in the 1990s. As an alternative to surgicaltreatment, the use of low doses of anticholinergic drugs has shown encouraging results for the primary treatmentofpatientswith hyperhidrosis, as well as for alleviating postoperative compensatory hyperhidrosis, without significant side effects, in preliminary studies conducted at the Hyperhidrosis Outpatient Clinic of the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP, University of São Paulo School of Medicine Hospital das Clínicas), located in the city of São Paulo, Brazil.

Our study has several limitations common to administrative databases. Residual confound- ing could account for some of the observed associations. However, this is minimized to the extent that we are using a good instrument for coiling. The F statistic in our analysis suggests a strong instrument. In addition, coding inaccuracies will undoubtedly occur and can affect our estimates. However, several reports have demonstrated that coding for aneurysm and cerebro- vascular disease has shown nearly perfect association with medical record review [19, 20]. Although SPARCS includes all hospitals from the entire New York State, the generalization of this analysis to the entire US population is uncertain. SPARCS does not provide any clinical information on the structure, size, or location of the aneurysms, which are important factors in cerebrovascular neurosurgery. However, the use of the instrumental variable analysis is attempting to control for unknown confounders such as these.
Lazarieva О.В. Methodological features of the physical rehabilitation in the surgicaltreatmentof vertebral pathology for patientswith kyphosis. The associate system is considered a spine – a pelvis – extremities. The program of physical rehabilitation ofpatients is presented. Maintenance and methodical features of leadthrough of procedure of medical gymnastics and massage in after operating and restoration periods is certain. The most informing indexes of biogeometrical type of carriages are exposed, characterizing kyphotic deformation of spine for patients. The special exercises for forming of dynamic stereotype and correction of deformations of locomotorium are offered. Directions the correction of biotgeometrical type of carriage are shown.
In making a detailed analysis of our sample, it can be noted that only the patientswith an unsatisfactory response to clinical treatment underwent surgery. Thus, these patients possibly had a more reserved prognosis in relation to those who had better evolution when approached in the same way. It is possible that the patients studied here had arterial margins that were more compromised, disease of a more aggressive character or muscle conditions that were less favorable than those in the patients who improved with clinical treatment. In this way, considering the good results obtained with this sample, we may infer that the surgicaltreatmentofpatients who do not necessarily experience improvement with clinical treatment will possibly bring results that are equal to or even more promising than clinical treatment. We believe that the role of surgery in the treatmentof IC must be reconsidered in the sense of expanding its coverage.
Results: We performed 100 procedures on 47 renal units (17 bilateral, 7 withrecurrent stones). Urinary tract infection/colonization was seen in 21 of 23 patients, most of whom had more than one organism. The stone-free rate was 96%. Six patients required three or more procedures, each had a complete staghorn calculus. In an average of 36 months of follow-up, 10 patients (46%) had recurrent stone disease requiring intervention, and 5 patients (23%) underwent repeat PNL. The stone composition analysis revealed mainly infection-related stones.
Abstract: Epithelial ovarian cancer (EOC) is the most common type of ovarian cancer; representing 90% of all ovarian cancers. The viruses are known as human malignancies agents. We tried to analyze the presence of Hepatitis B Virus infection in women with epithelial ovarian carcinoma. PCR-based detection of HBV infections was carried out on 50 tissue samples from patientswith histologically proven EOC using consensus primers. The samples analyzed showed 8% (4/50) positivity for HBV-DNA in cancerous ovarian tissues. All of the positive patients had serous adenocarcinoma and advanced stage disease. The results of this study suggest that hepatitis B could play a major role in the etiology of ovarian cancer.
Of the 6 patients who received selective embolisation for AVF, 4 (67%) were male and 2 (33%) were female. Mean age was 52 years (range: 42-57). There was no urinary anomaly identiied among the patients. All patients had complex ‘staghorn’ stones. Mean operation time was 138 minutes (range: 50-300). Four patients (67%) had two accesses and two patients (33%) had one access. Entry to the lower pole was performed via subcostal puncture. Secondary entries were made into the middle and upper poles. Punctures into the middle and upper poles were always performed above the 12 th rib.
Exclusion criteria were patients who were operated using the Essex-Lopresti technique or those in whom a minimally invasive surgery was performed; fractures treated conser- vatively due to patient’s own reasons or lack ofsurgical indication; associated fractures; lack of adequate skin con- dition, edema, and blisters in the lateral aspect of the foot, not resolved by the date of the surgery; absence of clini- cal conditions due to vascular disorders, heart disease, or decompensated diabetes; severe traumatic brain injury; psy- chosocial problem; heavy smoking; refusal to undergo surgical
Several aspects justified this research, namely: difficulties in establishing drug treatment or other drugs indicated to eliminate CAF; complications caused by CAF, especially thromboembolism with increasing morbidity and mortality; presence of previous heart disease, most often injury of the mitral valve; advances in the study of the electrophysiological mechanisms of arrhythmia; description of the focal origin mechanism of AF in the pulmonary veins, as well as foci located in the vena cava; and demonstration that the ablations performed with US systems, through both endocardial and epicardial, are likely to cause transmural lesion. Thus, the aim of this study was to evaluate the surgicaltreatmentof CAF with US in patientswith mitral valve disease, considering preoperative clinical characteristics ofpatients undergoing surgicaltreatment for CAF and follow-up in the immediate postoperative period, at hospital discharge, and late postoperative of up to 60 months.
When the disease has indication for surgery, the intervention is selected from a number ofsurgical op- tions. The beneits of a more extensive procedure that enhances the disease cure, reduces the long-term risk of cancer and improves the functional result should be analyzed versus a less extensive procedure, which may be safer in speciic clinical situations. It is impor- tant to emphasize that most patients want to avoid a deinitive ileostomy. In addition, the development of an intestinal restorative technique with ileal pouch- anal anastomosis (IPAA) is the procedure of choice to treat patientswith UC 4 .
The diagnosis of urinary retention was done when the residual volume, obtained by post micturi- tion urethral catheterization, was higher than 100 ml. Patients which could not present spontaneous mictu- rition in the immediate post-operative period were maintained in a clear intermittent catheterization pro- gram until 4 weeks post-operatively when a loosen- ing procedure was performed if retention had per- sisted. All of the patients that presented spontaneous micturition in early post-operative period showed post-void residual less than 100 ml and were consid- ered without retention. Following the above criteria, postoperative urinary retention occurred in 3 patients (6.7%) that had not presented spontaneous micturi- tion after 4 weeks post-operatively. All underwent sling tension loosening under local anesthesia and voided spontaneously, with completed relief of irri- tative symptoms and with a mean post void residual volume of 60 ml after the procedure.
mechanical grinding and polishing. Back scattered electrons (BSE) were utilized in SEM in order to reveal difference in chemical compositions of microcomponents present in particular samples. The SEM investigations were used to reveal the distribution of graphite and other big particles. Transmission electron microscopy (TEM), on the other hand, was applied for examination of nanosized secondary precipitates, i.e. vanadium or niobium carbides and/or nitrides (or carbonitrides). The thin foil technique was implemented for this purpose. The 3 mm disks were ground down on sand papers and then dimpled to about 0.1 mm thickness. Afterwards the disks were further thinned in an ion mill until a perforation had appeared. The TEM investigation was carried out by means of a JEOL 2010 ARP analytical scanning transmission electron microscope operating at acceleration voltage of 200 kV. Imaging was performed by conventional transmission mode while for chemical analysis (X-ray Energy Dispersive Spectroscopy - EDS) the nanoprobe mode was utilized. The nanoprobe mode enabled to obtain electron probes approaching a few nanometers in diameter (practically about 10 nm because at smaller electron probes the number of X-ray counts is usually too low for analysis). The EDS analysis was performed by Oxford-Link system attached to the microscope. The Oxford- Link system was equipped with Si(Li) detector. This system detects all elements down to boron. In order to examine the crystallography of precipitates the Selected Area Diffraction (SAD) patterns analysis was also performed.
As we know that to find the area of sector the angle made by the chord (that is chord which divides the circle) is required. But in the below method we find the ratio of the segments of the circle. Thus by relating the area of segment to the area of sector the area of sector could be found. The ratio of area of segments is related to tangents that are drawn through diameter on either side.
Schwannoma is a rare benign tumor of the proximal tracheobronchial tree. The aim of the present study is to report a case of tracheal schwannoma causing airway obstruction. A 16-year-old woman complained of cough, wheezing and dyspneia. Bronchoscopy and computerized tomography showed a polypoide intratracheal mass obstructing approximately 80% of the lumen. The treatment consisted of tracheal resection and primary anastomosis. Histological analysis revealed a tracheal schwannoma. The postoperative course was uneventful and the patient remains well twelve months after surgery.
