    Although in literature achondroplasia has been described profusely, reports on achondroplastic twins are limited. We present two cases of monozygotic female twins with achondroplasia, who underwent limb-lengthening surgical procedure with external fixation in the following five steps: tibia, femur, tibia; femur, homer. Both the cases presented a good limb length and an optimal correction of associated deformities after the treatment, fulfilling the indications. Surgical indications were mostly led by the axial deviations of the lower limbs, and the timing of the limb-lengthening procedures has been the same in both couples showing the importance of this aspect.

  3. Surgical correction of pectus excavatum.

    It has been observed that some patients who had correction of funnel chest deformity by methods which failed to provide fixed elevation of the involved sternal segment developed progressive sagging in later years in spite of looking good at the operating table. This has led to the adoption of a new technique of double sternal support. This procedure has resulted in 35 of 37 children (94%) being classified as excellent or satisfactory. This double support was initially established in 1959 by overlapping the upper transsected sternum while maintaining elevation of the lower end with a soft tissue sling of perichondrium and intercostal muscle. Beginning in 1961, a rigid bridge of rib or stainless steel bar was substituted at the lower end of the sternum. This has provided better support and the current preference of using the steel bar has been validated in this group of patients. The few disappointments were related to removal of the bar earlier than desired, failure to excise all the protruding sternal cartilage stumps or rib graft tips and inability to cover the lateral sternal edges with pectoral muscles. If possible, the steel bar should not be removed before 12 mo. When these pitfalls were avoided, the results were almost uniformly excellent. The wisdom of excising all depressed cartilaginous segments, as advocated by Ravitch in 1949, has been substantiated. A submammary transverse incision has provided an excellent cosmetic appearance. The morbidity has been low and the mortality zero. In spite of the absence of objective evidence of cardiopulmonary dysfunction, there seems to be an almost uniform improvement in appearance and in patient activity following successful correction of the funnel chest. The latter may be as much a psychological response as a physiologic one. The low morbidity, satisfactory long term results, and general improvement in the patient's body image and outlook on life indicate the need to offer correction of the severe pectus excavatum

    The surgical correction of vertical malpositions of the human eye has been made relatively safe and reliable by recent surgical techniques. The authors define this condition as vertical orbital dystopia and review the etiology of this deformity in 38 recent consecutive cases that were surgically treated at the Craniofacial Anomalies Center of The University of Virginia. Some new and useful tests are described that are of value to the plastic surgeon in analysis of the facial deformity and in planning the appropriate surgical procedure to correct the vertical dystopia of one or both eyes. Several cases are illustrated that describe the principal surgical methods of moving the eye up or down without loss of vision. The vertical eye shifts in this series have been in the range of 2 to 3 mm to over 22 mm. No loss of vision was produced by these corrections. The most common difficulties and complications of orbital dystopia corrections are described. The implications of this type of surgery in terms of visual physiology are suggested. The authors conclude that surgical correction of vertical orbital dystopias is possible, safe, and rewarding to the patients. However, they advise that the correction is best performed in young children and by a specially trained team of plastic surgeons, neurosurgeons, and ophthalmologists.

    Full Text Available Purpose: Myelomeningocele is one of the most common birth defects. It is associated with severe neurological deficiencies, and ocular changes, such as strabismus, are very common. The purpose of this study was to describe indications for strabismus surgery in patients with myelomeningocele and to evaluate the results achieved with surgical correction. Methods: We retrospectively reviewed records of all patients with myelomeningocele who underwent surgery for strabismus correction in a 5-year period in an institution for disabled children. Results: The main indications for strabismus surgery were esotropia and A-pattern anisotropia. Excellent surgical results were achieved in 60.9% of patients, satisfactory in 12.2%, and unsatisfactory in 26.9%. Conclusion: Patients with myelomeningocele and strabismus had a high incidence of esotropia and A-pattern anisotropia. Strabismus surgery in these patients had an elevated percentage of excellent and satisfactory results, not only for the ocular deviation, but also for improvement of head posture.

    Surgical cleft repair aims to restore function of the oro-nasal sphincter and oro-nasal soft tissues and re-establish the complex relationship between perioral and perinasal muscle rings without compromising subsequent mid-facial growth and development. Here we review the surgical anatomy of this region, optimal timing for surgical repair and current thinking on the use of surgical adjuncts. In addition, an overview of current surgical techniques available for the repair of cleft lip, cleft palate and velopharyngeal insufficiency is presented. Finally, we briefly discuss nasal revision surgery and the use of osteotomy, including distraction osteogenesis in the cleft patient.

    Full Text Available SUMMARY Introduction: anovulation is a major cause of female infertility, and polycystic ovary syndrome (PCOS is the leading cause of anovulation. While undergoing drug-induced ovulation, women with PCOS usually have a satisfactory response recruiting follicles, but some are unable to recruit follicles or often produce an excessive number of follicles, which can result in ovarian hyper-stimulation syndrome and/or multiple pregnancy. Surgical laparoscopy with ovarian "drilling" may prevent or reduce the need for drug-induced ovulation. Objective: to identify the current indications of laparoscopic ovarian drilling and the best surgical technique. Method: a review of the medical literature based on systematic search in the Medline, Lilacs and Cochrane databases, using as keywords laparoscopy, polycystic ovary syndrome, and drilling. Results: we found 105 articles in the literature, 27 of these highly relevant, describing findings on ovarian drilling. Conclusion: laparoscopic drilling is indicated for patients with polycystic ovary syndrome with ovulatory resistance to the use of clomiphene citrate, body mass index less than 30 kg/m2 and preoperative luteinizing hormone above 10 IU/L. The preferred surgical technique should be the realization of 5 to 10 perforations on the surface of each ovary bilaterally using monopolar energy.

    An 8 week old infant with severe heart failure from type 1 truncus arteriosus underwent successful corrective surgery employing the Rastelli procedure with use of deep hypothermia and total circulatory arrest. Postoperative hemodynamic studies showed complete closure of the septal defect, disappearance of truncal stenosis, but presence of mild porcine valve stenosis. This procedure is possible even in very small subjects and is preferable to palliative pulmonary arterial banding.

    Achilles tendon pathologic conditions are implicated in contributing to the development of many diabetic foot complications including diabetic foot ulceration and Charcot neuroarthropathy. Surgical correction of the diabetic equinus deformity has been studied as an isolated or adjunctive treatment when dealing with difficult-to-close diabetic foot ulcerations or when surgically addressing the diabetic Charcot neuroarthropathy foot or ankle. This article reviews the most common indications, complications, and surgical procedures for equinus correction by either a tendo-Achilles lengthening or gastrocnemius recession for the management of diabetic foot conditions.

    BACKGROUND: Some patients with chronic pancreatitis (CP) may require surgery mainly because of intractable pain, suspicion of malignancy, or complications related to CP. This study aimed to analyze the efifcacy of surgical treatment for patients with CP in terms of pain relief, control of local complications, and pancreatic endocrine/exocrine function. METHODS: Twenty-six patients with CP were treated surgically at our hospital from June 1985 to November 2005. The clinical data of these patients were analyzed retrospectively. RESULTS:  The follow-up time ranged from 8 to 130 months with a median of 60.6 months. No patients were lost to follow-up. All patients had improvement of clinical symptoms such as abdominal pain, steatorrhea and weight loss, to some degree, especially pain relief in patients with good dilation and high pressure of the main pancreatic duct. The endocrine and exocrine functions were not alleviated in all patients, otherwise the impaired glucose tolerance was improved in 8 (30.8%), 15 (57.7%) maintained the same body weight, one (3.8%) had an acute attack of CP, and 2 (7.7%) developed pancreatic carcinoma in the 16th and 28th month postoperatively and died within 3 years after operation for CP. The 1-, 3-, 5-year pain-free rates of CP patients were 96.2%(25/26), 88.5%(23/26) and 84.6%(22/26), respectively. CONCLUSIONS: In selected patients with CP, surgical treatment is a safe procedure and can effectively relieve pain and control local complications;also, it is helpful to improve the quality of life for patients with pancreatitis, and to control the development of this disease.

    Full Text Available Aim. To determine a method of extra-articular osteochondral fragment formation for the improvement of surgical correction results of joint deformities and optimization of regenerative conditions for hyaline cartilage. Materials and Methods. The method of formation of an articular osteochondral fragment without penetration into the joint cavity was devised experimentally. More than 30 patients with joint deformities underwent the surgery. Results. During the experiments, we postulated that there may potentially be a complete recovery of joint defects because of hyaline cartilage regeneration. By destructing the osteochondral fragment and reforming it extra-articularally, joint defects were recovered in all patients. The results were evaluated as excellent and good in majority of the patients. Conclusion. These findings indicate a novel method in which the complete recovery of joint defects due to dysplastic genesis or osteochondral defects as a result of injuries can be obtained. The devised method can be used in future experiments for objectification and regenerative potential of hyaline cartilage (e.g., rate and volume of the reformed joints that regenerate, detection of cartilage elements, and the regeneration process.

    Full Text Available The regularity of publishing corrections, clarifi cations, and letters to the editor, entail a high level of respect among the media for their audiences as they signify accountability and media credibility.This study began on the general assumption that the Croatian media is reluctant to publish corrections regularly, projecting an image that errors simply do not occur. Certainly errorless reporting is impossible due to fact that journalism is a profession prone to human error. Therefore, this study has enacted a content analysis methodology to follow the four primary Croatian daily newspapers, Jutarnji list, Večernji list, 24 sata and Vjesnik, for the period between May 6 and 30, 2010. The primary conclusion is that Croatian newspaper editors are hesitant to publish corrections if they are not under pressure from the Media Law.

    To study the evolution of deformity of the proximal interphalangeal joint over 5 years after good surgical correction of Dupuytren-induced contracture. We assessed 63 patients (72 fingers; 69 hands) with Dupuytren disease for the degree of contracture, its correction after surgery, and the range of movement at the proximal interphalangeal joints at 3 and 6 months, and 1, 3, and 5 years after fasciectomy with or without the use of a firebreak graft. We investigated associations between the recurrence of contracture and preoperative patient and surgical factors. There were 4 patterns of evolution of contracture after surgical correction. A total of 31 patients (33 hands) showed good improvement that was maintained for 5 years (minimal recontracture group). Twenty patients (23 hands) showed good initial improvement, which mildly worsened ( 20°) but there was no further worsening (severe early recontracture group). Eight patients (8 hands) worsened progressively over 5 years (progressive recontracture group). Worsening of contracture more than 6° between 3 and 6 months after surgery predicted progressive recontracture at 5 years. Recurrence of contracture (not disease recurrence) could be predicted as early as 6 months after surgery for Dupuytren disease. Copyright © 2013 American Society for Surgery of the Hand.

    Full Text Available Objective: The webbed neck deformity or pterygium colli is the number one symptom of the Turner syndrome that leads the patient to consult a doctor. Various but rare surgical approaches have been described to correct this deformity. We reviewed our experience with the surgical correction of the pterygium colli.Methods: Through five clinical cases, we describe the surgical technique with a lateral approach which provides a better control of the operative site, allows for the excision of the underlying trapezial fascial web, thus preventing recurrence seen in the posterior approach, and restores a normal hairline. Results: No postoperative wound infection occurred. No recurrence was observed through 24 months. Three patients developed hypertrophic scars.Conclusion: The lateral approach associated with an advanced flap and a Z-plasty is an effective technique for correction of this neck deformity. The presence of a multidisciplinary team, formed with maxillofacial and plastic surgeons, endocrinologists and psychologists, is required to treat these patients allowing reintegration into society and family.

    The evaluation of drug-resistant epileptics in view of causal surgical epilepsy therapy aims at accurate identification of the 'epileptogenic area'. Definition of the 'epileptogenic area', which is not synonymous or coexistent with the 'lesional area', as a positively defined area of seizure onset is obtained through the recording and analysis of spontaneous habitual seizures with electrodes placed in or close to the presumed epileptogenic brain areas. Interictal epileptiform field potentials are important too. Long-term intracranial recording techniques include direct intracerebral stereotactic depth-recording (stereo-electroencephalography, SEEG) and epicortical recordings with the use of foramen ovale as well as subdural strip and grid electrodes. The use of SEEG requires rigorous criteria, and the anatomy and vessels of the individual brain must be known in terms of a stereotactic reference system. Multi-contact flexible hollow-core electrodes are stereotactically implanted into strategically important targets, according to the evaluation strategy for a given patient. For presurgical assessment of potential candidates for selective amygdalo-hippocampectomy we have developed a less invasive extracerebral recording technique. It consists of bilateral insertion of solid four-contact electrodes via the foramen ovale, with positioning of the tips of the electrodes at the end of the ambient cistern. This technique permits stable and excellent recording from the mediobasal limbic structures of both temporal lobes. Personal experience with long-term extra-operative intracranial recording and stimulation now includes 131 patients evaluated with SEEG and 109 patients evaluated with foramen ovale electrodes.

    2009-02-01

    Full Text Available Abstract Background The correction of trunk deformity is crucial in scoliosis surgery, especially for the patient's self-image. However, direct visualization of external scoliotic trunk deformity during surgical correction is difficult due to the covering draping sheets. Methods An optoelectronic camera system with 10 passive markers is used to track the trunk geometry of 5 scoliotic patients during corrective surgery. The position of 10 anatomical landmarks and 5 trunk indices computed from the position of the passive markers are compared during and after instrumentation of the spine. Results Internal validation of the accuracy of tracking was evaluated at 0.41 +/- 0.05 mm RMS. Intra operative tracking during surgical maneuvers shows improvement of the shoulder balance during and after correction of the spine. Improvement of the overall patient balance is observed. At last, a minor increase of the spinal length can be noticed. Conclusion Tracking of the external geometry of the trunk during surgical correction is useful to monitor changes occurring under the sterile draping sheets. Moreover, this technique can used be used to reach the optimal configuration on the operating frame before proceeding to surgery. The current tracking technique was able to detect significant changes in trunk geometry caused by posterior instrumentation of the spine despite significant correction of the spinal curvature. It could therefore become relevant for computer-assisted guidance of surgical maneuvers when performing posterior instrumentation of the scoliotic spine, provide important insights during positioning of patients.

    2017-01-01

    Sagittal craniosynostosis remains the most common type of isolated craniosynostosis, accounting for nearly half of all nonsyndromic cases. The clinical diagnosis is typically made on the basis of a scaphocephalic head shape and is confirmed by computed tomography or magnetic resonance imaging. The current review examines the major surgical options for correction of isolated sagittal craniosynostosis, including their complications and short- and long-term outcomes. Reconstructive techniques have benefited from advances in perioperative anesthesia monitoring and improved safety of blood transfusion. Although extensive calvarial remodeling is considered safe and may confer greater long-term skull shape correction and decreased neuropsychological sequelae, minimally invasive techniques, such as device-assisted expansion of the cranium continue to increase in popularity. This review underscores the need for additional prospective studies comparing different techniques to determine the optimal reconstructive approach for correction of sagittal craniosynostosis.

    Tetralogy of Fallot is the most common cyanotic congenital cardiac lesions. Although pregnancy in patients with corrected tetralogy of Fallot usually have a satisfactory outcome, there may have maternal cardiovascular complications. To report our experience in monitoring and treatment of 16 pregnancies in 14 women with tetralogy of Fallot. Prospective study performed in 16 pregnancies of 14 patients with tetralogy of Fallot, who attended the services of Cardiology and High Risk Pregnancy in the Hospital de Gineco-Obstetricia of the Centro Médico de Occidente (Mexico), from January 1997 to January 2010. Nine women had total surgical correction and five hadn't. All patients obtained complete study protocol and tests of fetal wellbeing. Hemoglobin and hematocrit were significantly higher in the group without surgical correction; this group also had lower oxygen saturation and right ventricular enlargement. Of the 16 pregnancies, five were resolved vaginally, the other by cesarean section. The cyanotic mothers had premature termination of pregnancy, lower birth weight and Apgar slightly deteriorated. There were no maternal or neonatal deaths, neither cardiac malformation in newborns. There are more risks for the binomial in patients with uncorrected tetralogy of Fallot and in those operated with significant residual lesions. A greater anatomical impact was significantly correlated with major hemoglobin and minor oxygen saturation, which are the most important risk factors for adverse fetal outcomes.

    Full Text Available A two-and-a-half-year-old giant lop-eared rabbit, weighing 5.1 kg, presented with a one-month history of intermittent right hind limb lameness. The limb locked in extension during hopping. On examination, a grade-2 medial patellar luxation of the right hind was diagnosed, with associated stifle joint swelling. Radiographic findings of the right stifle comprised periarticular osteophyte formation consistent with mild degenerative joint disease and joint effusion. Surgical correction involving right trochlear wedge recession sulcoplasty and lateral imbrication was carried out to stabilise the patella in the trochlear groove. The right hind limb lameness resolved, and the patella was stable at a 6-month postoperative examination. One year postoperatively, the right patella was luxating again concurrent with bilateral stifle effusions. Euthanasia was performed twenty months after surgery due to recurrent lameness in the right hind limb.

    A male (30 years five months) who complained of mandibular prominence and masticatory dysfunction was diagnosed as a mandibular prognathic with acromegaly after cephalometric and endocrine examinations. The level of growth hormone (GH) subsequent to a transsphenoidal hypophysectomy had been controlled by medicines for about five years. Surgical orthodontic correction improved his occlusion and profile, but magnetic resonance imaging detected a recurrent adenoma in the cranial base during the retention period. The recurrence resulted in slight prognathic changes of the patient with a high level of GH. This is a case report of the treatment of an acromegalic patient discussing growth considerations that could influence the orthodontic treatment plan and long-term stability.

    To investigate how displacements of maxillo-mandibular structures are associated with each other at splint removal and 1 year post-surgery following 1-jaw and 2-jaw surgeries for correction of Class III malocclusion. Fifty patients who underwent surgical correction with maxillary advancement only (n = 25) or combined with mandibular setback (n = 25) were prospectively enrolled in this study. Cone-beam computed tomographies were taken pre-surgery, at splint removal and at 1 year post-surgery. Three-dimensional cranial base superimpositions and shape correspondence were used to measure the outcomes from pre-surgery to splint removal (surgical changes) and splint removal to 1 year post-surgery (post-surgical adaptations). Pearson's correlation coefficients were used to evaluate the association between the regional displacements. Both surgery groups presented mandibular clockwise rotation with surgery and post-surgical adaptive counterclockwise rotation. In patients treated with maxillary advancement only, the surgical changes of the maxilla were significantly correlated with chin changes. The amount and direction of chin autorotation were significantly correlated with right and left ramus autorotation. Right and left condylar displacements were significantly correlated. One year post-surgery, adaptive displacements and bone remodeling of both rami were correlated with the chin and condylar changes. For the 2-jaw group, the few correlations between the positional and remodeling changes in the anatomic regions of interest observed due to the surgery were different than those observed after post-surgical adaptations, suggesting that these changes occurred independently. Our results indicate that surgical displacements and post-surgical adaptations are often correlated in one-jaw surgery and are, in general, independent in two-jaw surgery. © 2015 John Wiley & Sons A/S.

    Adult acquired flatfoot deformity is a degenerative disease causing medial arch dysfunction. Surgical correction has typically involved tendon reconstruction with calcaneal osteotomy; however, the postoperative changes have not been fully characterized. The present study assessed the success of surgical correction of Stage IIb adult acquired flatfoot deformity through changes in plantar pressures and patient-generated outcome scores. With Institutional Review Board approval, 6 participants were evaluated before and after surgery using pedobarography, the Foot and Ankle Outcome Score, and the Medical Outcomes Study 36-item short-form questionnaire. The plantar pressures were recorded using a TekScan HRMat(®) during walking and in a 1- and 2-foot stance. The resulting contour maps were segmented into 9 regions, with the peak pressure, normalized force, and arch index calculated. Surgical effects were analyzed using paired t tests. Postoperatively, the Foot and Ankle Outcome Score and Medical Outcomes Study 36-item short-form questionnaire scores increased significantly from 180 ± 78 to 360 ± 136 (p < .03) and 47 ± 18 to 71 ± 19 (p = .06), respectively. During the 2-foot stance, the normalized force had increased significantly in the lateral midfoot (p < .03), although no significant differences were found in peak pressures. No significant differences were observed in the 1-foot stance. During walking, the normalized force increased significantly in the lateral mid- and forefoot (p < .05). The peak pressure increased significantly in the lateral forefoot (p < .01). The arch index values demonstrated no significant changes. The increased questionnaire scores indicated that surgical correction improved the self-perceived health of the participants. Lateral shifts in the peak pressure and normalized force suggest that forefoot and midfoot loading is altered postoperatively, consistent with the goal of offloading the dysfunctional arch. Thus, the present study has

    The purpose of this study was to assess the effects of surgical correction of pectus carinatum on health-related quality of life and self-esteem. Between May 2012 and May 2013, a prospective observational single-center cohort study was conducted on consecutive patients undergoing surgical correction of pectus carinatum at our institution. Patients filled in questionnaires on health-related quality of life and self-esteem before and six months after surgery. Disease-specific health-related quality of life was improved by 33% (95% CI: 23; 44%) according to responses to the Nuss Questionnaire modified for Adults. The improvement for generic mental health-related quality of life was 7% (95% CI: 3; 12%) in responses to the Short Form-36 Questionnaire. The improvement in self-esteem was 9% (95% CI: 2; 17%) as assessed with the Rosenberg Self-Esteem Scale. A Single Step Questionnaire supported the improvements in health-related quality of life and self-esteem six months postsurgery. This study confirms positive effects of surgical correction of pectus carinatum on health-related quality of life and self-esteem. Patients were to a greater extent self-satisfied about chest appearance following surgery, indicating this to be a step in the right direction toward improved body image, mental health and self-esteem.

    For young, active patients with healthy hip cartilage, pelvic osteotomy is a surgical option in to address hip pain and to improve mechanical loading conditions related to dysplasia. Hip dysplasia may lead to arthrosis at an early age due to poor coverage of the femoral head and abnormal loading of the joint articulation. In patients with symptomatic dysplasia and closed triradiate cartilage (generally over age 10), including adolescents and young adults (generally up to around age 40), the Bernese periacetabular osteotomy (PAO) is a durable technique for addressing underlying structural deformity. The PAO involves a modified Smith-Petersen approach. Advantages of the Bernese osteotomy include preservation of the weight-bearing posterior column of the hemi-pelvis, preservation of the acetabular blood supply, maintenance of the hip abductor musculature, and the ability to effect powerful deformity correction about an ideal center of rotation. There is an increasing body of evidence that preservation of the native hip can be improved through pelvic osteotomy. In contrast to hip osteotomy and joint preservation, the role of total hip arthroplasty in young, active patients with correctable hip deformity remains controversial. Moreover, the durability of hip replacement in young patients is inherently limited. Pelvic osteotomy should be considered the preferred method to address correctable structural deformity of the hip in the young, active patient with developmental dysplasia. The Bernese PAO is technically demanding, yet offers reproducible results with good long-term survivorship in carefully selected patients with preserved cartilage and the ability to meet the demands of rehabilitation.

    Full Text Available Objective: to compare the efficiency of using the values of transpulmonary (PiCCO and prepulmonary (Swan-Ganz catheter thermodilution as guides to targeted therapy for hemodynamic disorders in the surgical correction of mixed cardiac valvular defects. Subjects and methods. The study enrolled 40 patients operated on for acquired cardiac diseases who were randomized to two matched groups. Hemodynamics was monitored by means of a Swan-Ganz catheter in Group 1 and by transpulmonary thermodilution in Group 2. Anesthesia was maintained with propofol and fentanyl. Infusion therapy was performed using crystalloid and colloid solutions. Continuous intravenous infusion of inotropic agents was used when heart failure was developed. Hemodynamic, clinical, and laboratory parameters were estimated intraoperatively and within 24 hours postoperatively. Results. The groups did not differ in the degree of baseline heart failure, the duration of an operation and myocardial ischemia, and the length of extracorporeal circulation. In the PiCCO group, postoperative infusion volume was 33% higher than that in the Swan-Ganz group, which ensured increases in stroke volume and oxygen delivery in the early postoperative period (p<0.05. Respiratory support was 26% shorter in the PiCCO group (p<0.04. Conclusion. After surgical interventions for mixed cardiac defects, the targeted therapy algorithm based on transpulmonary thermodilution provided more steady-state values of hemodynamics and oxygen transport, which was followed by the increased scope of infusion therapy and the shorter length of postoperative mechanical ventilation than that based on hemodynamics being corrected from the values of prepul-monary thermodilution. Key words: transpulmonary thermodilution, targeted therapy, prepulmonary ther-modilution, acquired heart disease.

    Full Text Available Introduction. Nuss procedure is a minimal invasive surgical technique based on retrosternal placement of a metal plate to correct pectus excavatum chest deformity. We are presenting our five­year (2006­2011 institutional experience of 21 patients. Objective. The aim of this study was to determine characteristics and advantages of minimal invasive surgical approach in correcting deformities of the chest. Methods. Surgical procedure, named after its author Nuss, involves the surgical placement of a molded metal plate, the so­called pectus bar, behind the sternum under thoracoscopic view whereby immediate controlled intraoperative corrections and stabilizations of the depression can be made. The great advantage of this method is reflected in a significant shortening of operative time, usually without indications for compensation in blood volume, and with a significantly shortened postoperative recovery that allows patients to quickly return to their normal activities. Results. In the period 2006­2011, 21 patients were operated by the Nuss procedure. The pectus bar was set in front or behind the muscles of the chest. Among the complications listed were inflammation of wounds in three patients, dislocation (shifting of the bar requiring a reoperation in two patients, an occurrence of a pericardial effusion in one patient, and allergic response to foreign body in one patient. Five patients required extraction of the bar two years later, and three patients after three years, all with excellent results. Conclusion. Minimally invasive Nuss procedure is safe and effective. It currently represents the primary method of choice for solving the chest deformity pectus excavatum for patients of all ages. Modification of thoracoscopic control allows a safe field of operation. Postoperative results are excellent with very few complications that can be attributed to the learning curve.

    Brain shift describes the deformation that the brain undergoes from mechanical and physiological effects typically during a neurosurgical or neurointerventional procedure. With respect to image guidance techniques, brain shift has been shown to compromise the fidelity of these approaches. In recent work, a computational pipeline has been developed to predict "brain shift" based on preoperatively determined surgical variables (such as head orientation), and subsequently correct preoperative images to more closely match the intraoperative state of the brain. However, a clinical workflow difficulty in the execution of this pipeline has been acquiring the surgical variables by the neurosurgeon prior to surgery. In order to simplify and expedite this process, an Android, Java-based application designed for tablets was developed to provide the neurosurgeon with the ability to orient 3D computer graphic models of the patient's head, determine expected location and size of the craniotomy, and provide the trajectory into the tumor. These variables are exported for use as inputs for the biomechanical models of the preoperative computing phase for the brain shift correction pipeline. The accuracy of the application's exported data was determined by comparing it to data acquired from the physical execution of the surgeon's plan on a phantom head. Results indicated good overlap of craniotomy predictions, craniotomy centroid locations, and estimates of patient's head orientation with respect to gravity. However, improvements in the app interface and mock surgical setup are needed to minimize error.

    Full Text Available The cleft lip and palate patients usually present a number of problems viz. altered oral anatomy leading to changes in oral physiology diminishing the self-cleansing ability of individual. The handicapped children are unable to maintain their oral hygiene properly. The present study was formulated with the aim that does normalization of oral anatomy have its effect on improvement of oral hygiene? An assessment of oral hygiene index-simplified was performed between preoperative and postoperative values in the same patient at KGMU and KGDU. A total of 50 cases were recorded in two groups of 25 each: (i < 6 years old and (ii > 6 years. The observations are statistically analyzed by paired ′t′ test to get the significance of results. Results: The data analyzed showed the significant decrease in oral hygiene indices observed in both groups. A relative significance in oral hygiene status following surgery was observed. Both groups expressed greater significance when compared pre and postoperatively which is indicative of considerable improvement of oral hygiene after surgical correction. The study concludes that oral hygiene improves more in older cleft lip-palate cases following reconstruction of palatal vault, premaxilla and anterior lip seal by secondary bone grafting method when compared with oral hygiene indices results in primary periosteoplasty cases. The surgical correction of cleft lip palate enhances self-cleaning ability and better compliance to maintain oral hygiene in children as the age advances.

    2017-04-01

    Sympathectomy and its variations have been performed in thoracic surgery for more than 100 years. However, its indications have undergone profound modifications in this period. Likewise, since then the surgical technique has also evolved dramatically up to the minimally invasive techniques worldwide accessible in present days. Currently, primary hyperhidrosis is, by far, the main indication for thoracic sympathectomy and this procedure is usually carried out thoracoscopically with excellent results. However, until today, hyperhidrosis is a part of thoracic surgery still surrounded by controversy, persisting as an open field over which some confusion still resides regarding its pathophysiology, terms definitions and operative approaches. The aim of this article is to provide a wide but easily comprehensible review of the theme, discussing and clarifying the major concepts with respect to its clinical presentation, all the presently available treatment options and strategies with their potential benefits and risks, the adequate patient selection for sympathectomy, as well as the postoperative clinical results.

  17. Arm rotated medially with supination – the ARMS variant: description of its surgical correction

    2009-03-01

    Full Text Available Abstract Background Patients who have suffered obstetric brachial plexus injury (OBPI have a high incidence of musculoskeletal complications stemming from the initial nerve injury. The presence of muscle imbalances and contractures leads to typical bony changes affecting the shoulder, including the SHEAR (Scapular Hypoplasia, Elevation and Rotation deformity. The SHEAR deformity commonly occurs in conjunction with Medial Rotation Contracture (MRC of the arm. OBPI also causes muscle imbalances at the level of the forearm, that lead to a fixed supination deformity (SD in a small number of patients. Both MRC and SD will cause severe functional limitations without surgical intervention. Methods Fourteen OBPI patients were diagnosed with MRC of the shoulder and SD of the forearm along with SHEAR deformity during a 16 month study period, with eight patients available to long-term follow-up (age range 2.2 – 18 years. Surgical correction of the MRC was performed as a triangle tilt or humeral osteotomy depending on the age of the child, after which, the patients were treated with a radial osteotomy to correct the fixed supination deformity. Function was assessed using the modified Mallet scale, examination of apparent supination and appearance of the extremity at rest. Results Significant functional improvements were observed in patients with surgical reconstruction. Mallet score increased by an average of 5.2 (p Conclusion The simultaneous presence of two opposing deformities in the same limb will visually offset each other at the level of the wrist and hand, giving the false impression of neutral positioning of the limb. In reality, the neutral-appearing position of the hand indicates a fixed supination posture of the forearm in the face of a medial rotation contracture of the shoulder. Both of these deformities require surgical attention, and the presence of concurrent MRC and SD should be monitored for in OBPI patients.

  18. New surgical technique to correct urovagina improves the fertility of dairy cows.

    Several surgical techniques have been proposed for the treatment of urovagina as a major cause of infertility in cows. However, so far no technique seems to be successful in all cases. Given that an incompetent or damaged constrictor vestibuli muscle is a feature of cows with urovagina, we hypothesized that surgical correction of urovagina by cerclage of the vestibulovaginal junction under the vaginal wall cranial to the urethral opening would prevent cranial flow of urine and improve fertility. Our study was performed on 39 non-pregnant lactating Holstein-Friesian cows suffering urovagina, with a vaginal content of urine exceeding 100mL and with evident incompetence of the constrictor vestibuli muscle. Cows were randomly assigned to a Control (untreated cows, n=20) or Experimental (n=19) group. An encircling polydioxanone suture was placed in the vaginal wall at the vestibulovaginal junction to create a vestibulovaginal cerclage in the Experimental cows. Surgery was observed to resolve urovagina in 17 (89.5%) of the 19 treated cows. Pregnancy was recorded in 7/20 (35%) and 14/19 (74%) cows in the Control and Experimental groups, respectively. Using logistic regression procedures and based on the odds ratio, we determined that cows undergoing surgical correction of urovagina were 5.2 times more likely to become pregnant than untreated cows (P=0.015). Our results suggest that vestibulovaginal junction cerclage prevents the cranial flow of urine and improves the function of the constrictor vestibuli muscle in cows suffering urovagina. They also indicate that, under these conditions, urovagina correction may dramatically increase fertility.

    Full Text Available The nail is a subject of global importance for dermatologists, podiatrists and surgeons. Nail avulsion is a frequently undertaken, yet simple, intriguing procedure. It may either be surgical or chemical, using 40% urea. The former is most often undertaken using the distal approach. Nail avulsion may either be useful for diagnostic purposes like exploration of the nail bed, nail matrix and the nail folds and before contemplating a biopsy on the nail bed or for therapeutic purposes like onychocryptosis, warts, onychomycosis, chronic paronychia, nail tumors, matricectomy and retronychia. The procedure is carried out mostly under local anesthesia with or without epinephrine (1:2,00,000 dilution. Besides the above-mentioned indications, the contraindications and complications of nail avulsion are briefly outlined.

    Although there is a growing body of evidence to document the safety and efficacy of operative treatment of carotid stenosis, surgical indications for elongation and kinking of the internal carotid artery remain controversial. The goal of this study was to evaluate the efficacy of surgical correction of internal carotid artery kinking in patients with persistent hemispheric symptoms despite antiplatelet therapy. A consecutive series of 81 patients (mean age, 64 years) underwent 83 surgical procedures to correct kinking of the internal carotid artery either by shortening and reimplanting the vessel on the common carotid artery, inserting a bypass graft, or transposing the vessel onto the external carotid artery. Mean follow-up was 56 months (range, 15-135 months). Study endpoints were 30-day mortality and any stroke occurring during follow-up. No postoperative death was observed. The postoperative stroke rate was 1%. Primary patency, freedom from neurologic symptoms, and late survival at 5 years (x +/- standard deviation) were 89 +/- 4.1%, 92 +/- 4%, and 71 +/- 6%, respectively. The findings of this study indicate that surgical correction for symptomatic stenotic kinking of the internal carotid artery is safe and effective in relieving symptoms and preventing stroke. Operative correction should be considered as the standard treatment for patients with symptomatic carotid kinking that does not respond to antiplatelet therapy.

  4. Surgical technique, fusion rates, and planovalgus foot deformity correction with naviculocuneiform fusion.

    2014-03-01

    Arthrodesis of the naviculocuneiform (NC) joints is not a common procedure, as it is perceived by many to be less reliable or less predictable than arthrodesis of proximal or distal joints in the medial column. There is a subset of patients with planovalgus feet, cavovarus feet, and degenerative arthritis who also have an apex of deformity at the NC joints in whom fusion is indicated. The surgical technique, fusion rates, and deformity correction data for NC fusion in planovalgus feet are evaluated in this report. Twenty-eight patients (33 feet) who underwent surgery between October 2008 and November 2012 were identified who had NC fusion as their only arthrodesis procedure. Medical records and radiographs were reviewed, and time to union was calculated. Twenty patients from that group underwent NC fusion for symptomatic planovalgus feet, and their preoperative and last postoperative weight-bearing radiographs were reviewed and compared for deformity correction. All patients were operated on by the senior author or a senior foot and ankle trainee during fellowship using the same surgical technique, and all patients followed a standardized postoperative rehabilitation protocol. Mean time to union for all 33 NC fusions was 21.7 ± 2 weeks (mean ± SEM). One patient underwent revision for nonunion, resulting in an arthrodesis rate of 97%. For NC fusions in those with planovalgus feet, an improvement in mean lateral talus-first metatarsal angle (Meary's line) from 12.3 ± 1.3 degrees to 5.2 ± 1.2 degrees (P treatment for their condition. NC fusion was a safe and predictable procedure for any of its indications, with a fusion rate similar to that of other joints in the foot albeit with a longer time to union. For patients with symptomatic and flexible planovalgus feet, NC fusion resulted in deformity correction in multiple planes and good symptomatic relief. Level IV, retrospective case series.

    2014-01-01

    Refractive errors are frequently found following cataract surgery and refractive lens exchange. Accurate biometric analysis, selection and calculation of the adequate intraocular lens (IOL) and modern techniques for cataract surgery all contribute to achieving the goal of cataract surgery as a refractive procedure with no refractive error. However, in spite of all these advances, residual refractive error still occasionally occurs after cataract surgery and laser in situ keratomileusis (LASIK) can be considered the most accurate method for its correction. Lens-based procedures, such as IOL exchange or piggyback lens implantation are also possible alternatives especially in cases with extreme ametropia, corneal abnormalities, or in situations where excimer laser is unavailable. In our review, we have found that piggyback IOL is safer and more accurate than IOL exchange. Our aim is to provide a review of the recent literature regarding target refraction and residual refractive error in cataract surgery.

    In patients with hypertrophic cardiomyopathy, myocardial fibrosis is an independent predictor of an adverse outcome. A new technique of hypertrophic obstructive cardiomyopathy (HOCM) surgical correction in patients with severe hypertrophy and septal myocardial fibrosis has been proposed. This approach avoids mechanical damage to the heart conduction system, and for the surgeon it improves visual inspection of the area to be resected. We present a case report of a 33-year old female patient with biventricular obstruction, extreme hypertrophy, septal myocardial fibrosis and episodes of ventricular tachycardia who underwent surgical correction according to this novel procedure. The advantage of the approach is an effective surgical treatment of HOCM in patients with severe hypertrophy and septal myocardial fibrosis who cannot be treated with the current surgical techniques.

    2014-10-01

    Most children with flatfeet are asymptomatic and will never require treatment. In general, flatfoot deformity is flexible and will not cause pain or disability; it is a normal variant of foot shape. Thus, it is essential to reassure and educate patients and parents. A flatfoot with a contracture of the Achilles tendon may be painful. In these cases, a stretching program may help relieve pain. Scant convincing evidence exists to support the use of inserts or shoe modifications for effective relief of symptoms, and there is no evidence that those devices change the shape of the foot. The surgeon must be vigilant to identify the rare rigid flatfoot. Indications for flatfoot surgery are strict: failure of prolonged nonsurgical attempts to relieve pain that interferes with normal activities and occurs under the medial midfoot and/or in the sinus tarsi. In nearly all cases, an associated contracture of the heel cord is present. Osteotomies with supplemental soft-tissue procedures are the best proven approach for management of [corrected] flatfoot.

    Presbyopia is an age-related eye condition where one of the signs is the reduction in the amplitude of accommodation, resulting in the loss of ability to change the eye's focus from far to near. It is the most common age-related ailments affecting everyone around their mid-40s. Methods for the correction of presbyopia include contact lens and spectacle options but the surgical correction of presbyopia still remains a significant challenge for refractive surgeons. Surgical strategies for dealing with presbyopia may be extraocular (corneal or scleral) or intraocular (removal and replacement of the crystalline lens or some type of treatment on the crystalline lens itself). There are however a number of limitations and considerations that have limited the widespread acceptance of surgical correction of presbyopia. Each surgical strategy presents its own unique set of advantages and disadvantages. For example, lens removal and replacement with an intraocular lens may not be preferable in a young patient with presbyopia without a refractive error. Similarly treatment on the crystalline lens may not be a suitable choice for a patient with early signs of cataract. This article is a review of the options available and those that are in development stages and are likely to be available in the near future for the surgical correction of presbyopia.

    Nasal deformity associated with cleft lip and palate is a highly challenging reconstructive problem in rhinoplasty. In the literature, several operative solutions and evaluation methods have been described, however these do not offer a standard procedure for the surgeon. Our aim was to standardize our surgical technique-as much as the uniqueness of each case allowed it-based on the most frequent deformities we had faced; and to evaluate our results via a postoperative patient satisfaction questionnaire. Between 2012 and 2014 12 consecutive patients with combined cleft lip and palate deformities underwent secondary nasal and septal correction surgery with the same method by the same surgeon. The indications of surgery were, on one hand, difficult nasal breathing and altered nasal function (tendency for chronic rhinosinusitis) and on the other hand the aesthetic look of the nose. No exclusion criteria were stated. In our follow-up study we evaluated our results by using a modified Rhinoplasty Outcome Evaluation (ROE) questionnaire: patients answered the same four questions pre- and postoperatively. Data were statistically analyzed by t-test. Based on the questionnaire, all patients experienced improvement of nasal breathing function, improved appearance of the nose and less stigmatization from the society. According to the t-test, all scores of the four questions improved significantly in the postoperative 4-6 months, compared with the preoperative scores. In our opinion with our standardized surgical steps satisfactory aesthetic and functional results can be achieved. We think the modified ROE questionnaire is an adequate and simple method for the evaluation of our surgical results.

    Full Text Available OBJECTIVE: To assess patient satisfaction and functional results at long term follow-up after surgical correction for Peyronie's disease (PD and congenital penile curvature (CPC with the technique of tunical plication. MATERIALS AND METHODS: One hundred and two men operated for PD (n = 76 or CPC (n = 26 in four different departments of urology in public hospitals agreed to answer a six-question telephone questionnaire about treatment satisfaction. Tunica albuginea plication procedures represented the standard surgical approach. Subjects under investigation were correction of the deformity, feeling of bumps under the skin, pain during erection, penile sensory changes, development of erectile dysfunction (ED and postoperative ability for complete vaginal intromission. Subjective response rates were compared using the chi square test on the basis of the etiology of the disease (CPC or PD. RESULTS: Significant differences (p < 0.05 between patients with CPC and PD were noticed in the prevalence of postoperative penile deformity, sensory changes, ED and ability to complete vaginal intromission, PD patients always showing a more pessimistic view. No significant differences (p = ns were detected in terms of unpleasant nodes under the penile skin or pain during erection. CONCLUSIONS: Long-term outcome after surgical correction for PD and CPC with the technique of tunical plication can be poor. Probably patient expectations are above the real performance of surgical techniques. Preoperative information should be more exhaustive.

    Full Text Available Surgical management is considered for specific indications in Crohn′s disease and a wide variety of surgeries is performed. The purpose of this pictorial essay is to depict manifestations of Crohn′s disease that indicates surgery, various surgical procedures that are performed, and the complications arising from these surgical procedures. Surgical indications including obstruction due to strictures or adhesions, fistulae and abscesses, and surgeries for these conditions, such as, ileocecectomy, stricturoplasty, small bowel resection, fecal diversion, segmental colectomy, and lysis of adhesions and their complications will be discussed and their imaging will also be illustrated.

  19. Rattlesnake bites in children: antivenin treatment and surgical indications.

    Shaw, Brian A; Hosalkar, Harish S

    2002-09-01

    Orthopaedic surgeons working in the Americas may be consulted in the care of patients bitten by venomous rattlesnakes (genus Crotalus ), particularly with regard to the possibilities of compartment syndrome and soft-tissue destruction. Despite considerable evidence regarding the safety and efficacy of antivenin in the treatment of rattlesnake bites in adults, controversy persists regarding the roles of antivenin and surgery in the treatment of rattlesnake envenomations in children. Our hypothesis is that aggressive use of antivenin is just as effective and safe for children as it is for adults. We retrospectively reviewed the charts of twenty-four consecutive patients who had been managed at our hospital because of a bite from a western diamondback rattlesnake. Nineteen of the twenty-four patients had been envenomated. The uniformity of collected data was facilitated by the use of an intensive-care-unit protocol during the ten-year period that was reviewed. A questionnaire was developed for long-term follow-up. Aggressive use of polyvalent equine antivenin safely prevented the need for surgery in sixteen of the nineteen envenomated patients. Of the three patients who had surgical treatment, two were managed with limited soft-tissue debridement and one was managed with a fasciotomy of the leg because of a compartment syndrome that occurred when adequate antivenin was withheld. No serious adverse effects were noted in association with the antivenin, and no functional impairments were noted at the time of discharge. Antivenin, rather than surgery, is the proper initial treatment of severe rattlesnake envenomations in children.

    2004-04-01

    Full Text Available Background. Alveolar process atrophy is a physiological process in edentulous patients that may heavily compromise the succes of dental prosthetic rehabilitation. This is particulary important for insertion of endosseous implants. Because of the direct vicinity of maxillary sinuses, implantation is often impossible without previous pre-prosthetic surgical intervention.Methods. Two types of pre-prosthetic surgical procedures are described and their relative advantages are discussed. An illustrative case report is presented, describing the patient’s problems, his treatment and clinical outcome.Conclusions. In cases when maxillary alveolar process atrophy is so severe that insertion of dental implants is impossible, surgical correction with sinus floor lift is necessary. In our institution, the results of this procedure are good. Good quality of the antral mucosa and normal anatomic shape of the maxillary sinuses are two prerequisites for its success.

    Hypertelorism is a deformity characterized by an increase in interorbital distance. The treatment can be orbital mobilization, or if the malformation goes along with occlusal alterations, the indicated treatment is a facial bipartition with hemifacial rotation.The intention of the present study was to describe a surgical planning technique in locating the anatomic points and planes on a stereolithographic model of a patient with 0-14 fissure and its surgical application.

    The surgical correction of the retention of upper canines is made easier by the direct bonding method, furthermore it increases the chances of successful treatment. At the same time at teen-age the treatment is usually missing, since the persistent milk-teeth in the place of impacted canines are ensuring the aesthetic effect. The late treatment is motivated by aesthetic aspects also by loosing the milk-canines. Thus the indication of the treatment is a cure only from the orthodontist's aspect, from the patient's view it's only the aesthetics.

    Patients with idiopathic scoliosis, although otherwise healthy, often have significant concerns about their self-image and appearance. In a group of juveniles and adolescents, this can impact adjustment in school, functioning in peer groups, and general sense of well-being. There are limited data to help physicians reliably and precisely identify those who are at higher risk of poor emotional adjustment even after spine deformity correction. The purpose of this study was to determine the predictors of emotional maladjustment in juvenile and adolescent patients after surgical correction of idiopathic scoliosis. A total of 233 juveniles, mean age 11.26 ± 1.02 (range, 8 to 12) years and 909 adolescents, mean age 14.91 ± 1.61 (range, 13 to 21) years, who underwent surgical correction for idiopathic scoliosis and who were participating in a prospective longitudinal multicenter database, were enrolled in the study. Participants completed the Scoliosis Research Society-22 (SRS-22) questionnaire before surgery and 2 years postoperatively. Radiographs were used to measure Cobb angle and surface measurements were used to determine decompensation and trunk shift. Adolescents reported poorer mental health preoperatively (Pself-image (Pself-image (Padolescent group, mental health 2 years postoperatively was predicted by preoperative mental health (Pself-image 2 years postoperatively was predicted by preoperative mental health (Pself-image (PSelf-image and mental health are significantly improved after spine deformity correction in juveniles and adolescents with idiopathic scoliosis. However, consistent with normative development, adolescents are at higher risk for emotional maladjustment than juveniles. Surgical decision making in scoliosis correction should take the emotional status of the patient into consideration.

    Background This study is an attempt to clarify the role of C-reactive protein (CRP) as a surgical indication marker for appendicitis. Methods One hundred and fifty patients who underwent appendectomies and had pathologically confirmed appendicitis were reviewed between May 1, 1999 and September 31, 2007. The correlation between preoperative clinical factors and the actual histological severity, and identify surgical indication markers were assessed by univariate and multivariate analyses. Results Univariate analysis showed that only the CRP level significantly differ between the surgical treatment necessary group (gangrenous appendicitis) and the possible non-surgical treatment group (catarrhalis and phlegmonous appendicitis). Multivariate analysis indicated only the CRP level to be a surgical indication marker for acute appendicitis. The receiver-operating characteristic (ROC) curve indicated that the cutoff value of CRP for surgical indication of appendicitis is 4.95 mg/dl. Conclusion Only the CRP level is consistent with the severity of appendicitis, and considered to be a surgical indication marker for acute appendicitis. PMID:19878592

    2007-04-01

    Full Text Available OBJECTIVE: The present work describes our experience in surgical correction of stress urinary incontinence, comparing both the TVT and the TVT-O techniques. METHOD: Between October 2001 and March 2004, 76 patients underwent the TVT procedure. Between January 2004 and January 2005, 98 surgical corrections of urinary incontinence were carried out using the TVT-O technique. RESULTS: Median operative time was 28 minutes for TVT and 7 minutes for TVT-O. Intraoperative complications for TVT occurred in 4 patients (6.6%: urinary bladder perforation in 3 patients (5%, p = 0.0228 and parietal peritoneum perforation in 1 case (1.6%. No intraoperative complications took place during TVT-O. Immediate postoperative complications: transient urinary retention in TVT, 2 cases (2.6% and overcorrection in TVT-O (1% which was readjusted within 24 hours. There were no late complications after TVT. There were 2 cases (2.04% with late complications in TVT-O. TVT and TVT-O resulted in correction of incontinence in 100% of the patients. CONCLUSION: TVT and TVT-O are two effective techniques for the correction of stress urinary incontinence. TVT-O would seem to be a technique much easier to perform resulting in less intraoperative complications.

    2010-12-01

    Full Text Available Background: A surgical technique for correction of complete unilateral cleft lip was done using a minor modification of Millard’s surgical technique. The purpose of this modification is to achieve a good anatomical form of columelia, nostril cill and the position of nasal tip. Purpose: This article presents the correction of the complete cleft lip which was done initially by correction of the slanted columella followed by correction of the nostril sill which was done before the sequence of closing the lip crevice. Case: Correction of a case with complete unilateral cleft lip on a fifteen year old girl using modification of Millard’s surgical technique is presented. Case Management: Rotation incision in the philtrum region was made as introduced by Millard to make a triangular flap. The triangular flap was contralaterally rotated and pulled into the direction of cleft to achieve a normal position of the columella and nasal tip. The lateral side of the ala was incised in circular form down to the alar base and straight through to the direction of cleft formed an alar flap which consisted of ala, clefted and slanted nasal base tissue. The tip of the triangular flap was trimmed and approximated to the alar flap to form a new the nostril sill. Adjustment of the size of the nostrill sill size was achieved during the approximation of those two flaps. The nasal base was built during approximation of the lateral and the medial segment flap or philtrum region and the base of new nostril sill. Surgical correction of the complete unilateral cleft lip including correction of the nostrill sill using approximation of triangular flap and the alar flap was achieved. Conclusion: This surgical technique with minor modification of Millard’s surgical technique can be used for correction of the complete unilateral cleft lip with extremely slanted columella and nasal tip to form thenostril sill.Latar belakang: Koreksi celah bibir komplit satu sisi telah

    Science.gov (United States)

    Mracek, J; Choc, M; Mracek, Z

    2010-02-01

    Decompressive craniotomy is usually carried out using decompressive craniectomy (osteoclastic decompressive craniotomy) when the bone flap is removed. In situations when the level of expansion does not call for decomopressive craniectomy, we do not remove the bone flap and we perform osteoplastic decompressive craniotomy. The indication is based on assessment and cross correlation of the following parameters: intracranial pressure,midline shift and the number of pathologies on CT, actual influence of antiedematous therapy, expected cerebral oedema progression and especially according to the size of the dural defect after duratomy. In the course of osteoplastic decompressive craniotomy, decompression is secured by the elevation of the unfixed bone flap during cerebral tissue expansion. After the oedema regression, the elevated bone flap spontaneously drops to its original position and is reattached. The danger of bone plate depression is eliminated with the use of a bevel bone cut using a Gigli saw. Osteoplastic decompressive craniotomy is an effective method of treating brain oedema when the degree of expansion does not require decompressive craniectomy.

    Carcinoma of the face is the skin disease most frequently encountered by plastic surgeons in everyday practice. Although basal cell carcinomas and squamous cell carcinomas are generally easy to recognize, their treatment remains subject to various schools of thought, or even individual practices, which are often difficult to define. This article defines a general plan of management of these tumours; their histological duality corresponds to a therapeutic duality. Resection of a basal cell carcinoma requires safety margins of 3 to 4 mm, versus at least 5 mm for a squamous cell carcinoma. In a high-risk subject, with a sclerodermiform carcinoma or undifferentiated squamous cell carcinoma, this safety margin may be as much as 10 mm or more. Frozen section examination is preferable in these situations. Six anatomical regions are studied selectively to define the main rules of reconstruction: nasal region, orbitopalpebral region, labial region, malar region, frontal region and auricular region. Each region will be subdivided into several subterritories, each requiring different strategies. The objectives, methods and indications of each reconstruction are selectively defined. The final strategy proposed is based not only on the author's personal experience, but also on the results of the national survey on carcinomas. As a complement to these therapeutic guidelines, the authors raise the problem of incomplete resection, which requires the definition of a peripheral infiltration index predictive of the recurrence rate. Surgery obviously cannot constitute exclusive treatment carcinomas, hence the value of presenting other methods currently available in the therapeutic armamentarium. Surveillance is essential in every case, determined by the patient's risk of recurrence or even metastatic dissemination.

  16. Problem in the surgical correction of long-face with vertical open bite

    Directory of Open Access Journals (Sweden)

    Coen Pramono D

    2005-12-01

    Full Text Available Long-face cases usually need both treatment of orthodontic and surgery. The problem appearing in the correction of long-face might be able to be related with some difficult factors such as the crowded teeth and excessive vertical height. A class III malocclusion and excessive open bite can be also followed in long face. This situation might worsen the facial aesthetic condition and increase the difficulty in orthodontic treatment. The orthodontic approach is oriented toward positioning the teeth pre-surgically to facilitate the surgical plan. The form of mandible which has grown in the downward direction in the area of mandible angle makes an extreme vertical open bite. The maxilla is usually presented with a maxillary hypolasia. Double-jaw surgery was done as the correction of the lower jaw alone would produce a flattened face appearance and difficulty in repositioning the mandible to achieve a good facial performance. Several cephalometric points were measured to observe the facial situation progress after surgery. Two cases of longface are reported, and the same surgical treatments were performed and showed different results.

    From 1946 to 1985 a total of 594 patients with Haglund's disease were treated. 165 of the 266, who had been surgically treated were questioned extensively and 32 of them clinically and radiologically examined. Besides details of indication, surgical technique and perioperative issue, the subjective result as compared with the morphological state after removal of exostoses, was noted particularly. This necessitated the introduction of new X-ray quantification techniques in addition of the procedures described in literature. 73% good, and further 20% acceptable results confirm the indication. Nevertheless the success of the method depends largely on a good surgical technique and especially on the post-operative care.

    Science.gov (United States)

    Baumeister, M; Kohnen, T

    2008-11-01

    There are two basic approaches for the surgical correction of presbyopia: increasing depth of focus (e.g. by means of multifocal laser abrasion of the cornea), Or restoring accommodation in the sense of a dynamic change in ocular refraction (accommodative intraocular lenses, scleral expansion). Pseudoaccommodative procedures are able to achieve satisfactory near vision, albeit at the price of lower performance in the intermediate range and decreased image quality. The restoration of accommodation remains problematic, partly because the mechanism of accommodation and the development of presbyopia are still not fully understood. Some surgical procedures are based on concepts, the validity of which is not confirmed or which even contradict experimental evidence. Thus, it is necessary to assess the results and presumed mechanisms critically and objectively.

    2002-10-01

    Full Text Available The study had the objective to evaluate the benefits of surgical indication for portal hypertension in schistosomiasis patients followed from 1985 to 2001. Schistosoma mansoni eggs were confirmed by at least six stool examinations or rectal biopsy. Clinical examination, abdominal ultrasonography, and digestive endoscopy confirmed the diagnosis of esophageal varices. A hundred and two patients, 61.3% male (14-53 years old were studied. Digestive hemorrhage, hypersplenism, left hypochondrial pain, abdominal discomfort, and hypogonadism were, in a decreasing order, the major signs and symptoms determining surgical indication. Among the surgical techniques employed, either splenectomy associated to splenorenal anastomosis or azigoportal desvascularization, esophageal gastric descompression and esophageal sclerosis were used. Follow-up of patients revealed that, independent on the technique utilized, a 9.9% of death occurred, caused mainly by digestive hemorrhage due to the persistence of post-treatment varices. The authors emphasize the benefits of elective surgical indication allowing a normal active life.

    Although deforming contractures of the lower extremities after acute cerebrovascular events are well documented in the literature, there is limited literature regarding specific surgical considerations for the correction of these deformities, which are nonosseus in nature. The equinovarus foot, regardless of its origin, is a challenging pathologic condition for the foot and ankle surgeon. It is critical to have a firm understanding of the cause and symptoms behind an equinovarus deformity before treatment. The clinical presentation is discussed with special attention to deformities in adults with rigid equinovarus deformities after cerebrovascular-related accidents or peripheral ischemic events.

    To determine the role of night orthosis use after surgical correction of Dupuytren contracture. We searched MEDLINE, EMBASE, CINAHL, AMED, OTSeeker, and CENTRAL for articles published from inception of the databases to August 2015. Assessment was undertaken by 2 independent reviewers (O.A.S. and S.A.). Methodological quality of randomized controlled trials was assessed using the Cochrane risk of bias tool and the Newcastle-Ottawa instrument. Seven studies met the standard for inclusion in this review. A total of 659 patients across these 7 studies were included in the analysis, with follow-up ranging from 3 to 72 months. None of the included studies assessed recurrence. The analysis revealed no significant improvement in range of motion of hand joints for patients who received a static night orthosis after Dupuytren surgery compared with patients without an orthosis. Similarly, no differences were found in patient-reported functional status across the 2 groups. The current literature does not appear to support the use of static night orthosis in addition to hand therapy after surgical correction of Dupuytren contracture. Therapeutic IV.

    Determining the biopsy site location of a skin cancer before treatment is often challenging. To study the implementation and effectiveness of biopsy site selfies as a quality improvement measure for correct surgical site identification. In the first phase, the ability of dermatologic surgeon and patient to definitively identify the biopsy site and whether photography was needed to ensure site agreement were recorded. In the second phase, patients were requested to take biopsy site selfies, and after implementation, similar data were collected including whether a biopsy site selfie was helpful for definitive site identification. In the first phase, the physician and patient were unable to identify the biopsy site 17.6% (49/278) and 25.5% (71/278) of cases, respectively. A photograph was needed in 22.7% of cases (63/278). After implementation of biopsy site selfies, the physician and patient were unable to identify the biopsy site 17.4% (23/132) and 15.2% (20/132) of cases, respectively. Biopsy site selfies were available for 64.1% of cases for which no internal image was available and critical for site identification in 21.4% of these cases. Biopsy site selfies has proven to be helpful for correct surgical site identification by both the physician and the patient and may also provide further reassurance and confidence for patients.

    Full Text Available Introduction The purpose to this work is to review systematically the morphological changes of the nostrils of patients undergoing surgery for correction of cleft lip and identify in the literature the issues involved in the evaluation of surgical results in this population. Review of Literature A review was conducted, searching for clinical evidence from MEDLINE. The search occurred in January 2012. Selection criteria included original articles and research articles on individual subjects with cleft lip or cleft palate with unilateral nostril anthropometric measurements before and after surgical correction of cleft lip and measurements of soft tissues. There were 1,343 articles from the search descriptors and free terms. Of these, five articles were selected. Discussion Most studies in this review evaluated children in Eastern countries, using different measurement techniques but with the aid of computers, and showed improved nostril asymmetry postoperatively compared with preoperatively. Conclusion There is a reduction of the total nasal width postoperatively compared with preoperative measurements in patients with cleft lip.

    Surgical correction of adult degenerative scoliosis is a technically demanding procedure with a considerable complication rate. Extensive blood loss has been identified as a significant factor linked to unfavorable outcome. To report on the complication profile and clinical outcomes obtained with less invasive image-guided surgical correction of degenerative (de novo) scoliosis in a high-risk population. Thirty patients (age, 64-88 years) with progressive postural impairment, back pain, radiculopathy, and neurogenic claudication caused by degenerative scoliosis were treated by less invasive image-guided correction (3-8 segments) by multisegmental transforaminal lumbar interbody fusion and facet fusions. With a mean follow-up of 19.6 months, intraoperative blood loss, curve correction, fusion and complication rates, duration of hospitalization, incidence of hardware-related problems, and clinical outcome parameters were assessed using multivariate analysis. Satisfactory multiplanar correction was obtained in all patients. Mean intraoperative blood loss was 771.7±231.9 mL, time to full ambulation was 0.8±0.6 days, and length of stay was 8.2±2.9 days. After 12 months, preoperative SF12v2 physical component summary scores (20.2±2.6), visual analog scale scores (7.5±0.8), and Oswestry disability index (57.2±6.9) improved to 34.6±3.9, 2.63±0.6, and 24.8±7.1, respectively. The rate of major and minor complications was 23.4% and 59.9%, respectively. Ninety percent of patients rated treatment success as excellent, good, or fair. Less invasive image-guided correction of degenerative scoliosis in elderly patients with significant comorbidity yields a favorable complication profile. Significant improvements in spinal balance, pain, and functional scores mirrored expedited ambulation and early resumption of daily activities. Less invasive techniques appear suitable to reduce periprocedural morbidity, especially in elderly patients and individuals with significant

    Full Text Available Coarctation of the aorta (AoCo accounts for 6–10% of congenital heart diseases in infants. We analysed echocardiographic findings of patients operated on for AoCo in the University Hospital for Children in Riga during the first year of life to evaluate the long-term findings. Fifty-nine children underwent surgical correction of AoCo at the age of 55 ± 61 days. The methods of surgical correction were anastomosis end-to-end (ETE in 29% (n = 17, subclavian flap aortoplasty (SFA in 64% (n = 38 and extended anastomosis end-to-end (EETE in 7% (n = 4. Recoarctation developed in 15 patients (25% with no difference between surgical techniques (P > 0.05. The recoarcation patients had left ventricle hypertrophy (left ventricle mass index (LVMi 76 ± 19 g/m2.7 normalising after angioplasty (LVMi 42 ± 7 g/m2.7. Patients with recoarctation had a decreased pulsed wave (PW Doppler systolic/diastolic ratio in abdominal aorta 2.3 ± 0.4 versus patientswithout recoarctation 5.3 ± 1.2 and the control group 6.3 ± 1.4 (P < 0.05. A high incidence of recoarctation exists in patients operated on for AoCo as small infants. Life-long surveillance is required to monitor and to intervene in a timely way. Supplementation of the echocardiographic protocol with an evaluation of PW Doppler flow pattern in abdominal aorta can provide additional information about the presence of obstruction.

    The purpose of this study was to compare postoperative clinical and radiological results in adolescent idiopathic scoliosis curves treated by posterior arthrodesis using autogenous bone graft from iliac crest (CI) versus only local autograft bone (HL). A retrospective matched cohort study was conducted on 73 patients (CI n=37 and HL n=36) diagnosed with adolescent idiopathic scoliosis and treated surgically by posterior arthrodesis. The mean post-operative follow-up was 126 months in the CI group vs. 66 months in the HL group. The radiographic data collected consisted of preoperative, postoperative, and final follow-up antero-posterior and lateral full-length radiographs. Loss of correction and quality of arthrodesis were evaluated by comparing the scores obtained from the Spanish version of the SRS-22 questionnaire. There were significant differences in the post-operative results as regards the correction of the Cobb angle of the main curve (HL 61 ± 15% vs. CI 51 ± 14%, P<.004), however a greater loss of correction was found in the local bone group (CI 4.5 ± 7.3° vs. HL 8.5 ± 6.3°, P=.02). There were no significant differences as regards the correction of the Cobb angle of the main curve at the end of follow-up. There were no clinical differences between the two groups in the SRS-22 scores. At 5 years of follow-up, there was a statistically significant greater loss of radiographic correction at the end of final follow-up in the local bone graft group. However clinical differences were not observed as regards the SRS-22 scores. Copyright © 2013 SECOT. Published by Elsevier Espana. All rights reserved.

    Despite advancements in medical therapy of Crohn’s disease (CD), majority of patients with CD will eventually require surgical intervention, with at least a third of patients requiring multiple surgeries. It is important to understand the role and timing of surgery, with the goals of therapy to reduce the need for surgery without increasing the odds of emergency surgery and its associated morbidity, as well as to limit surgical recurrence and avoid intestinal failure. The profile of CD patients requiring surgical intervention has changed over the decades with improvements in medical therapy with immunomodulators and biological agents. The most common indication for surgery is obstruction from stricturing disease, followed by abscesses and fistulae. The risk of gastrointestinal bleeding in CD is high but the likelihood of needing surgery for bleeding is low. Most major gastrointestinal bleeding episodes resolve spontaneously, albeit the risk of re-bleeding is high. The risk of colorectal cancer associated with CD is low. While current surgical guidelines recommend a total proctocolectomy for colorectal cancer associated with CD, subtotal colectomy or segmental colectomy with endoscopic surveillance may be a reasonable option. Approximately 20%-40% of CD patients will need perianal surgery during their lifetime. This review assesses the practice parameters and guidelines in the surgical management of CD, with a focus on the indications for surgery in CD (and when not to operate), and a critical evaluation of the timing and surgical options available to improve outcomes and reduce recurrence rates.

    Full Text Available Abstract Surgically correctable forms of primary aldosteronism are characterized by unilateral aldosterone hypersecretion and renin suppression, associated with varying degrees of hypertension and hypokalemia. Unilateral aldosterone hypersecretion is caused by an aldosterone-producing adenoma (also known as Conn's adenoma and aldosteronoma, primary unilateral adrenal hyperplasia and rare cases of aldosterone-producing adrenocortical carcinoma. In these forms, unilateral adrenalectomy can cure aldosterone excess and hypokalemia, but not necessarily hypertension. The prevalence of primary aldosteronism in the general population is not known. Its prevalence in referred hypertensive populations is estimated to be between 6 and 13%, of which 1.5 to 5% have an aldosterone-producing adenoma or primary unilateral adrenal hyperplasia. Taking into account referral biases, the prevalence of surgically correctable primary aldosteronism is probably less than 1.5% in the hypertensive population and less than 0.3% in the general adult population. Surgically correctable primary aldosteronism is sought in patients with hypokalemic, severe or resistant forms of hypertension. Recent recommendations suggest screening for primary aldosteronism using the aldosterone to renin ratio. Patients with a raised ratio then undergo confirmatory suppression tests. The differential diagnosis of hypokalemic hypertension with low renin includes mineralocorticoid excess, with the mineralocorticoid being cortisol or 11-deoxycorticosterone, apparent mineralocorticoid excess, pseudo-hypermineralocorticoidism in Liddle syndrome or exposure to glycyrrhizic acid. Once the diagnosis is confirmed, adrenal computed tomography is performed for all patients. If surgery is considered, taking into consideration the clinical context and the desire of the patient, adrenal vein sampling is performed to detect whether or not aldosterone hypersecretion is unilateral.

    Skeletal anterior open bite (AOB) or apertognathism is characterized by the absence of contact of the anterior teeth and affects articulation parameters, chewing, biting and voice quality. The treatment of AOB consists of orthognatic surgical procedures. The aim of this study was to evaluate the effects of treatment on voice quality, articulation and nasality in speech with respect to skeletal changes. The study was prospective; 15 patients with AOB were evaluated before and after surgery. Lateral cephalometric x-ray parameters (facial angle, interincisal distance, Wits appraisal) were measured to determine skeletal changes. Before surgery, nine patients still had articulation disorders despite speech therapy during childhood. The voice quality parameters were determined by acoustic analysis of the vowel sound /a/ (fundamental frequency-F0, jitter, shimmer). Spectral analysis of vowels /a/, /e/, /i/, /o/, /u/ was carried out by determining the mean frequency of the first (F1) and second (F2) formants. Nasality in speech was expressed as the ratio between the nasal and the oral sound energies during speech samples. After surgery, normalizations of facial skeletal parameters were observed in all patients, but no statistically significant changes in articulation and voice quality parameters occurred despite subjective observations of easier articulation. Any deterioration in velopharyngeal insufficiency was absent in all of the patients. In conclusion, the surgical treatment of skeletal AOB does not lead to deterioration in voice, resonance and articulation qualities. Despite surgical correction of the unfavourable skeletal situation of the speech apparatus, the pre-existing articulation disorder cannot improve without professional intervention.

    Full Text Available Introduction: Accomodative esotropia is secondary to inappropriate convergence during accomodative effort in an uncorrected hyperope and is often familial. Case presentation: we report the case of 20 year old Caucasian patient with congenital esotropia alternating, of 30 prism diopters distance (5 m and 40 prism diopters of esotropia at near, in both eyes. Measures: Was performed strabismus, in peribulbar anesthesia, the right medial rectus was cashed 3.0mm, the left medial rectus was collected 3.5 mm. Results: Immediately after surgery, the patient complained of intermittent diplopia, resolved with orthotic exercise which stimulated binocular vision, Conclusion: This case report suggests that the surgical correction strabismus, should be considered with due caution in the treatment of congenital esotropia alternating and branches, and in some clinical scenarios selected to avoid the complication of postoperative diplopia, that in the case report resolved so benign. After three months surgical treatmen, remains a small angle strabismus aesthetically acceptable, has not given double vision and remains abnormal retinal correspondence with orthotic exercise.

    A cohort of adult acquired flatfoot deformity rigid-body models was developed to investigate the effects of isolated tendon transfer with successive levels of medializing calcaneal osteotomy (MCO). Following IRB approval, six diagnosed flatfoot sufferers were subjected to magnetic resonance imaging (MRI) and their scans used to derive patient-specific models. Single-leg stance was modeled, constrained solely through physiologic joint contact, passive soft-tissue tension, extrinsic muscle force, body weight, and without assumptions of idealized mechanical joints. Surgical effect was quantified using simulated mediolateral (ML) and anteroposterior (AP) X-rays, pedobarography, soft-tissue strains, and joint contact force. Radiographic changes varied across states with the largest average improvements for the tendon transfer (TT) + 10 mm MCO state evidenced through ML and AP talo-1st metatarsal angles. Interestingly, 12 of 14 measures showed increased deformity following TT-only, though all increases disappeared with inclusion of MCO. Plantar force distributions showed medial forefoot offloading concomitant with increases laterally such that the most corrected state had 9.0% greater lateral load. Predicted alterations in spring, deltoid, and plantar fascia soft-tissue strain agreed with prior cadaveric and computational works suggesting decreased strain medially with successive surgical repair. Finally, joint contact force demonstrated consistent medial offloading concomitant with variable increases laterally. Rigid-body modeling thus offers novel advantages for the investigation of foot/ankle biomechanics not easily measured in vivo.

    Full Text Available The purpose was to reveal patterns of morphometric characteristics variability of lumbar vertebrae and sacrum for a choice of more adequate selection of standard sizes and introduction orientation of corrigent metalware at surgical treatment of spondylolisthesis. Preparations of lumbar vertebrae and sacrum of 60 skeletons, 110 Kt-grams of men and women of the first and second periods of mature age without visible pathology of a backbone and 300 Kt-grams of patients with spondylolisthesis. The data on age variability and sexual dimorphism of lumbar vertebrae and sacrum were obtained. The analysis of results of surgical treatment of 288 patients with spondylolisthesis during 1995-2008 was carried out. 160 patients were managed with preoperative planning, taking into account morphometric characteristics of vertebrae and sacrum since 2003. It is necessary to install and arrange metalware at reduction taking into account features of back structures and forward basic complex of lumbar vertebrae and sacrum; that allows to receive adequate decompression of neurovascu-lar structures in 85-90% cases, reliable correction and stabilization of damaged lumbosacral segments

    A 10-y-old ovariohysterectomized ring-tailed lemur (Lemur catta) was presented for exacerbation of respiratory signs. The lemur had a history of multiple examinations for various problems, including traumatic lacerations and recurrent perivulvar dermatitis. Examination revealed abnormal lung sounds and a femoral arteriovenous fistula with a palpable thrill and auscultable bruit in the right inguinal area. A diagnosis of congestive heart failure was made on the basis of exam findings, radiography, abdominal ultrasonography, and echocardiography. The lemur was maintained on furosemide until surgical ligation of the fistula was performed. Postoperative examination confirmed successful closure of the fistula and resolution of the signs of heart failure. Arteriovenous fistulas are abnormal connections between an artery and a vein that bypass the capillary bed. Large arteriovenous fistulas may result in decreased peripheral resistance and an increase in cardiac output with consequent cardiomegaly and high output heart failure. This lemur's high-flow arteriovenous fistula with secondary heart failure may have been iatrogenically induced during blood collection by prior femoral venipuncture. To our knowledge, this report is the first description of an arteriovenous fistula in a prosimian. Successful surgical correction of suspected iatrogenic femoral arteriovenous fistulas in a cynomolgus monkey (Macaca fascicularis) and a rhesus macaque (Macaca mulatta) have been reported previously. Arteriovenous fistula formation should be considered as a rare potential complication of venipuncture and as a treatable cause of congestive heart failure in lemurs.

    Plantar fibromatosis is a rare, benign lesion involving the plantar aponeurosis. Eleven patients (13 feet) underwent 24 operations, including local excision, wide excision, or complete plantar fasciectomy. Clinical results were evaluated retrospectively. There were no differences among the subgroups in postoperative complications. Two primary fasciectomies did not recur. Three of six revised fasciectomies, seven of nine wide excisions, and six of seven local excisions recurred. Our results indicate that recurrence of plantar fibromatosis after surgical resection can be reduced by aggressive initial surgical resection.

    Full Text Available Background: Degenerative lumbar scoliosis surgery can lead to development of adjacent segment degeneration (ASD after lumbar or thoracolumbar fusion. Its incidence, risk factors, morbidity and correlation between radiological and clinical symptoms of ASD have no consensus. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and certain imperative parameters. Materials and Methods: 98 patients who had undergone surgical correction and lumbar/thoracolumbar fusion with pedicle screw instrumentation for degenerative lumbar scoliosis with a minimum 5 year followup were included in the study. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and imperative patient parameters like age at operation, sex, body mass index (BMI, medical comorbidities and bone mineral density (BMD. The radiological parameters taken into consideration were Cobb′s angle, angle type, lumbar lordosis, pelvic incidence, intercristal line, preoperative existence of an ASD on plain radiograph and magnetic resonance imaging (MRI and surgical parameters were number of the fusion level, decompression level, floating OP (interlumbar fusion excluding L5-S1 level and posterolateral lumbar interbody fusion (PLIF. Clinical outcomes were assessed with the Visual Analogue Score (VAS and Oswestry Disability Index (ODI. Results: ASD was present in 44 (44.9% patients at an average period of 48.0 months (range 6-98 months. Factors related to occurrence of ASD were preoperative existence of disc degeneration (as revealed by MRI and age at operation ( P = 0.0001, 0.0364. There were no statistically significant differences between radiological adjacent segment degeneration and clinical results (VAS, P = 0.446; ODI, P = 0.531. Conclusions: Patients over the age of 65 years and with preoperative disc degeneration (as revealed by plain radiograph and MRI were at a higher risk of developing ASD.

    Bone and bone marrow functions of the reconstructed chest wall after surgical correction of the funnel chest deformities were evaluated by scanning method. In our series, three kinds of operative procedures were employed; strut method for adult cases, sternal turnover method with and without muscle pedicle for infant cases. Bone function was scanned by sup(99m)Tc-methylene-diphosphonate and bone marrow function was evaluated by sup(99m)Tc-sulfur-colloid. For the cases undergone each surgical procedure, bone and bone marrow scan were done at short term after surgery (within 30 days), at intermediate stage (one month to 12 months), and at long term stage (beyond one year). The results were as follows: By the evaluation at the long term stage of the cases undergoing strut method, bone as well as bone marrow scan visualized normal view of the reconstructed sternum. Regarding the cases undergone sternal turnover method without muscle pedicle, or free graft implantation of the plastron, the bone scan at the long term follow-up stage showed abnormal finding, i.e. hypo-, or defect-visualization of the inverted sternum, in 11.5% of the cases. Furthermore, bone marrow scan showed abnormality in 33.3% of the cases. On the other hand, the cases undergone sternal turnover method with muscle pedicle, in which blood supply to the plastron were preserved by the connection from superior epigastric artery to internal mammary artery, showed no abnormality as far as at the long term follow-up study neither in bone scan nor bone marrow scan. However, in the evaluation at short term after surgery, 50% of the cases undergoing bone scan showed abnormality. In addition, in this stage 85.7% of the bone marrow scan showed abnormal finding. These abnormality, however, normalized within 6 months for bone scan and 12 months for bone marrow scan, in contrast to the results of the cases undergone sternal turnover without pedicle.

    Full Text Available Superior mesenteric artery (SMA syndrome is a rare condition caused by compression of the third portion of duodenum by the angle between the superior mesenteric artery against the aorta. A rare presentation of SMA syndrome is following scoliosis repair and spinal fusion with a low incidence and most of these patients present with symptoms within one to two weeks or even more after the surgical repair. A high suspicion index after surgical correction of scoliosis with well-known risk factors (low BMI, low percentile of weight for height, and a high degree of change in the Cobb's angles can anticipate the postoperative diagnosis. Management has been described for postsurgical scoliosis repair with a late onset presentation of SMA syndrome with nutritional support with good success rates, but there is no data for best treatment management for acute onset especially when the surgical correction of the spine causes complete duodenal obstruction and a surgical intervention might be warranted. Here in, we present a 14 year-old boy with an acute 24-h postoperative SMA syndrome following surgical correction of scoliosis.

    The indicator kriging (IK) is one of the most efficient nonparametric methods in geo-statistics. The order relation problem in the conditional cumulative distribution values obtained by IK is the most severe drawback of it. The correction of order relation deviations is an essential and important part of IK approach. A monotone regression was proposed as a new correction method which could minimize the deviation from original quintiles value, although, ensuring all order relations.

    Assessment of respiratory muscle strength provides important diagnostic and prognostic information. Normative data in healthy, term infants is, however, limited. Surgically correctable birth defects, congenital diaphragmatic hernia (CDH) and abdominal wall defects (AWD), commonly have impaired diaphragm function. The study aims were to obtain normative data for respiratory muscle strength in healthy, term born infants at birth and at 6 weeks postnatal age (PNA) and to investigate the influence of growth and maturation on inspiratory muscle strength in CDH/AWD infants. Maximal inspiratory (cPimax) and expiratory (cPemax) pressures during crying were measured at birth in 67 healthy, term born infants (mean (SD) gestational age (GA) 39.4 (1.7) weeks) and reassessed in 27 at 6 weeks PNA. cPimax and functional residual capacity (FRC) (22.3 (4.2) ml/kg) were also measured in 23 infants with AWD/CDH (mean (SD) GA 36.9 (2.1) weeks) and reassessed in 16 at median (range) 6.5 (1.5-15) months PNA. In healthy infants, mean (SD) cPimax was 88.8 (19.33) cmH2 O and cPemax 61.8 (13.5) cmH2 O at birth, increasing significantly at followup to 100.9 (15.2) cmH2 O (P muscle strength compared to healthy term born infants but strength increases markedly in early life.

    Various surgical techniques to correct urovagina in cows describe creating a mucosal extension from the urethral orifice to the labia; however, a fistula often forms in the mucosal extension. The objective of the present study was to determine if the incidence of fistula formation could be decreased by covering transposed submucosal tissue on the dorsal aspect of the urethral extension with a mucosal graft. Cows in both the control group (19) and the experimental group (19) received a modified McKinnon technique of urethral extension; cows in the experimental group also had a sheet of mucosa, obtained from the dorsal aspect of the vestibule, grafted to submucosa exposed during creation of the urethral extension. During histological examination of the biopsy of the graft and its recipient site (harvested 1 week after surgery), neither inosculation nor revascularization of the graft was evident in any sample. Fourteen of 19 (74%) cows in the control group and 10 of 19 (53%) cows in the experimental group developed a fistula in the extension (P=0.18). We concluded that application of a mucosal graft to the subcutaneous tissue exposed to the vestibule using the McKinnon technique of creating a urethral extension was of little or no benefit in preventing the formation of a fistula in the extension. Furthermore, during evaluation of the extensions, digital palpation alone was often insufficient for detection of a fistula.

    Full Text Available Background Since the time of Paul Harrington numerous implants have been introduced for correction of scoliosis, but none are ideal. Newer devices are very expensive, and in our country some patients cannot afford them. Objectives The aim of this study was to compare the results of the Harrington rod (HR device and the newer Cotrel-Dubousset (CD device in treatment of adolescent idiopathic scoliosis (AIS. Materials and Methods A retrospective review assessed patients with AIS admitted for spinal curve correction treated with HR (n = 120 and CD devices (n = 138 between October 1988 to April 2001 at the Shafa Yahyaeian Hospital, Tehran, Iran. We extracted information from the patient’s file and radiographs before, after and two years post-operation. Results The mean age of patients was 16.7 ± 2.5 years. There was no statistically significant difference between the two groups regarding gender, age, curve before surgery, and percentage of flexibility. The mean curvature was 70 ± 20.7 in the HR and 64.81 ± 19.4 in the CD group before surgery (P = 0.09; and the mean curvature was 40 ± 16.3 and 26.58 ± 15.37 in HR and CD groups respectively after surgery (P = 0.156. The mean curvature was 47.2 ± 15.9 in HR and 31.2 ± 15.4 in CD groups at two years follow-up (P = 0.156. Conclusions Results of many studies have shown no significant impairment in long-term quality of life and function in patients treated with Harrington rods. According to previously performed studies and the current study, surgical correction with Harrington rods seem to be comparable with the newer more expensive CD device. Although there is no doubt that the preference is to use newer devices in view of some disadvantages of HR, but this does not preclude using it for patients that cannot afford the newer devices.

    The spinal anomaly designated dorsal dysraphism with lipoma (lipomyeloschisis) consists of skin-covered, focal spina bifida; focal partial clefting of the dorsal half of the spinal cord; continuity of the dorsal cleft with the central canal of the cord above (and occasionally below) the cleft; deficiency of the dura underlying the spina bifida; deep extension of subcutaneous lipoma through the spina bifida and the dural deficiency to insert directly into the cleft on the dorsal half of the cord; variable cephalic extension of lipoma into the contiguous central canal of the cord; and variable ballooning of the subarachnoid space to form an associated meningocele. The variable individual expressions of the anomaly are best understood by reference to their archetypal concept. Careful analysis of radiographic and surgical findings in human lipomyeloschisis and correlation with an animal model of lipomyeloschisis indicate that plain spine radiographs and high-resolution metrizamide computed tomographic myelography successfully delineate the precise anatomic derangements associated with lipomyeloschisis and provide the proper basis for planning surgical therapy of this condition.

    Purpose: The aim of this study is to report the indications, techniques, and clinical outcomes of corneal transplantation and investigate any changing trends in surgical techniques over a 6 year period. Materials and Methods: Records of patients who had undergone any kind of corneal transplantation at Labbafinejad Medical Center, Tehran, Iran, from January 2004 to December 2009 were reviewed to determine the indications and types of corneal transplantation. Postoperative best-corrected visual acuity, refractive error, graft clarity, and complications were reported. Results: During this period, 1859 eyes of 1624 patients with a mean age of 41.3 ± 21.3 years underwent corneal transplantation. The most common indication was keratoconus (38.4%) followed by aphakic/pseudophakic bullous keratopathy (11.7%), previous failed grafts (10.6%), infectious corneal ulcers (10.1%), non-herpetic corneal scars (7.6%), trachoma keratopathy (4.7%), stromal corneal dystrophies (4.6%), post-herpetic corneal scar (3.7%), Fuchs’ endothelial dystrophy (0.8%), and congenital hereditary endothelial dystrophy (0.4%). Techniques of corneal transplantation included penetrating keratoplasty (PKP; 70.9%), deep anterior lamellar keratoplasty (DALK; 20.1%), conventional lamellar keratoplasty (LKP; 4.4%), and Descemet's stripping automated endothelial keratoplasty (DSAEK; 2.3%). Over the study period, there was a significant increase in the relative frequency of infectious corneal ulcers, failed grafts, and trachoma keratopathy. Additionally, a significant reduction was observed in PKP and LKP procedures, and volume of DALK and DSAEK increased significantly. At final follow-up, 69.0% of grafts were clear in the PKP group. This figure was 82.6%, 82.7%, and 97.6% in the DALK, LKP, and DSAEK groups, respectively. Conclusion: Keratoconus was the most common indication and PKP was the most prevalent technique used for corneal transplantation. However, significant changes in the indications and

    Full Text Available Congenital cataracts constitute an important part of blindness in childhood. It’s a curable disease which is one of the most common causes of blindness in childhood. Main treatment is surgical operation. Timing of surgery, appropriate and rapid post sur- gery visual rehabilitation have a major effect on prognosis. Surgery should be perfor-med as soon as possible after the diagnosis in order to prevent amblyopia.Visual rehabi- litation of congenital cataract includes optical correction and amblyopia treatment. The most effective treatment of amblyopia is occlusion therapy. In this article congenital cataracts were evaluated in the light of recent literature and the importance of the timing of surgery and visual rehabilitation were attempted to be emphasized.

    Full Text Available Solar radiation reflected by the Earth's surface to satellite sensors is modified by its interaction with the atmosphere. The objective of applying an atmospheric correction is to determine true surface reflectance values and to retrieve physical parameters of the Earth's surface, including surface reflectance, by removing atmospheric effects from satellite images. Atmospheric correction is arguably the most important part of the pre-processing of satellite remotely sensed data. Such a correction is especially important in cases where multi-temporal images are to be compared and analyzed. For agricultural applications, in which several vegetation indices are applied for monitoring purposes, multi-temporal images are used. The integration of vegetation indices from remotely sensed images with other hydro-meteorological data is widely used for monitoring natural hazards such as droughts. Indeed, the most important task is to retrieve the true values of the vegetation status from the satellite-remotely sensed data. Any omission of considering the effects of the atmosphere when vegetation indices from satellite images are used, may lead to major discrepancies in the final outcomes. This paper highlights the importance of considering atmospheric effects when vegetation indices, such as DVI, NDVI, SAVI, MSAVI and SARVI, are used (or considered and presents the results obtained by applying the darkest-pixel atmospheric correction method on ten Landsat TM/ETM+ images of Cyprus acquired from July to December 2008. Finally, in this analysis, an attempt is made to determine evapotranspiration and to examine its dependence on the consideration of atmospheric effects when multi-temporal image data are used. It was found that, without applying any atmospheric correction, the real daily evapotranspiration was less than the one found after applying the darkest pixel atmospheric correction method.

    The assessment and management of tricuspid valve disease have evolved substantially during the past several years. Whereas tricuspid stenosis is uncommon, tricuspid regurgitation is frequently encountered and it is most often secondary due to annular dilatation and leaflet tethering from right ventricular remodelling. The indications for tricuspid valve surgery to treat tricuspid regurgitation are several and mainly related to the underlying disease, to the severity of insufficiency and to the right ventricular function. Surgical tricuspid repair has been avoided for years, because of the misleading concept that tricuspid regurgitation should disappear once the primary left-sided problem has been eliminated. Instead, during the last decade, many investigators have reported evidence in favor of a more aggressive surgical approach to functional tricuspid regurgitation, recognising the risk of progressive tricuspid insufficiency in patients with moderate or lesser degrees of tricuspid regurgitation and tricuspid annular dilatation. This concept, along with the long-term outcomes of principal surgical repair techniques are reported and discussed. Last, novel transcatheter therapies have begun to emerge for the treatment of severe tricuspid regurgitation in high-risk patients. Hence, very preliminary pre-clinical and clinical experiences are illustrated. The scope of this review is to explore the anatomic basis, the pathophysiology, the outcomes and the new insights in the management of functional tricuspid regurgitation.

    OBJECTIVE To determine the main clinical indications for surgical removal of the eye in rural areas in Cameroon. DESIGN Retrospective non-comparative case series. PARTICIPANTS A total of 253 patients presenting to the Manna eye clinic Nkongsamba who underwent destructive eye surgery (DES) between January 2006 and December 2010 were reviewed. MAIN OUTCOME MEASURE Age, gender, occupation, prior medication, visual acuity, operation indications, and type of operation. RESULTS There were 58.10% (n = 147) men and 41.90% (n = 106) women. Median age was 29 years (interquartile range: 14–69 years); age ranged from 10 to 88 years. A total of 67.19% (n = 170) of participants were farmers and lived in rural zones. In all, 79.05% (n = 200) confessed to have trying a medication before the presentation. Surgical indications included infective causes (perforated corneal ulcer 33.20% (n = 84) and endophthalmitis 18.20% (n = 46)), trauma 17.40% (n = 44), painful blind eyes 11.50% (n = 29), malignancy 10.70% (n = 27), and others 9.10% (n = 23). CONCLUSION The most common causes of DES in this series could be avoided. Therefore, preventive measures including extensive health education of the public and traditional healers on the risks linked to the use of traditional medicines in ophthalmology and the late presentation of eye disease, quality control of the campaigns that offer free cataract operations in the country.

    The Nuclear Regulatory Commission (NRC) is considering the use of cause codes as performance indicators (PIs) to monitor licensee performance. In conjunction with the cause codes, corrective action codes are also under consideration to describe licensee corrective actions for problems as represented by the cause codes. The set of cause codes and corrective actions employed in a trial program to assess their usefulness included: (1) administrative error -- training; (2) design/installation -- procedure modification; (3) fabrication error -- discipline; (4) random equipment failure -- management change; (5) licensed operator error -- design modification; and (6) other personal error -- equipment replacement/adjustment. These causes were selected to represent a broad range of licensee programs, hence the designation of programmatic PIs, that could be monitored in a systematic manner to identify trends in performance. They should establish a basis and focus for further investigation of a particular programmatic area if undesirable trends are evidence. 2 figs.

    Temporomandibular joint ankylosis (TMJA) is a severe disorder described as an intracapsular union of the disc-condyle complex to the temporal articular surface with bony fusion. The management of this disability is challenging and rarely based on surgical and rehabilitation protocols. We describe the treatment in two young adults affected by Goldenhar syndrome and Pierre Robin sequence with reankylosis after previous surgical treatments. There are three main surgical procedures for the treatment of TMJA: gap arthroplasty, interpositional arthroplasty, and joint reconstruction. Various authors have described reankylosis as a frequent event after treatment. Treatment failure could be associated with surgical errors and/or inadequate intensive postoperative physiotherapy. Surgical treatment should be individually tailored and adequate postoperative physiotherapy protocol is mandatory for success. PMID:24624260

    Indicators of weaning success have been tested primarily in patients who have been ventilated for short periods of time, and they may not be as accurate in cases where support has been required for longer than a few days. In patients requiring longer periods of support it is difficult to estimate the likelihood of successful liberation. Therefore we evaluated established weaning indices for their accuracy in surgical patients who required > or = 72 hours of mechanical ventilation. Surgical patients who required mechanical ventilation for > or = 72 hours were prospectively followed (over 6 months). We obtained standard indices of ventilatory function daily once patients were ready to wean. These indices included the respiratory rate/tidal volume ratio (RSBI), the maximal inspiratory pressure, and the minute ventilation. The duration of weaning and explicitly defined episodes of fatigue were the outcomes of interest. Statistical analyses evaluated the multiple factors that might influence the duration of weaning. Ninety-five patients (66% trauma; 34% surgery) survived to begin weaning, and 93% were liberated. The median duration of mechanical ventilation prior to weaning was 4 days (range 3-16 days), and the median duration of weaning was 3 days (range 0-56 days). Fatigue occurred in 36 patients and was not reliably predicted by any of the weaning measurements. However, a RSBI of > 105 on the first day of weaning was associated with prolonged weaning. By multivariate analysis, an RSBI of > 105 on the first day of weaning predicted prolonged weaning (hazard ratio 1.9; p = 0.03). After 72 hours of mechanical ventilation, clinical fatigue and successful liberation are not reliably predicted by standard indices of respiratory muscle strength and reserve. However, an RSBI of >105 observed once the patient is ready to wean is associated with prolonged weaning.

    In decades of technical developments after the first surgical corrections of spinal deformities, the set of devices, techniques, and tools available to the surgeons has widened dramatically. Nevertheless, the rate of complications due to mechanical failure of the fixation or the instrumentation remains rather high. Indeed, basic and clinical research about the principles of deformity correction and the optimal surgical strategies (i.e., the choice of the fusion length, the most appropriate instrumentation, and the degree of tolerable correction) did not progress as much as the implantable devices and the surgical techniques. In this work, a software approach for the biomechanical simulation of the correction of patient-specific spinal deformities aimed to the identification of its biomechanical principles is presented. The method is based on three-dimensional reconstructions of the spinal anatomy obtained from biplanar radiographic images. A user-friendly graphical user interface allows for the planning of the desired deformity correction and to simulate the implantation of pedicle screws. Robust meshing of the instrumented spine is provided by using consolidated computational geometry and meshing libraries. Based on a finite element simulation, the program is able to predict the loads and stresses acting in the instrumentation as well as those in the biological tissues. A simple test case (reduction of a low-grade spondylolisthesis at L3–L4) was simulated as a proof of concept, and showed plausible results. Despite the numerous limitations of this approach which will be addressed in future implementations, the preliminary outcome is promising and encourages a wide effort toward its refinement.

    OBJECTIVE The objective of this study was to evaluate the clinical efficacy of posterior-only surgical correction of dystrophic scoliosis in patients with neurofibromatosis Type 1 (NF1) using a multiple anchor point method (MAPM). METHODS From 2005 to 2014, 31 patients (mean age 13.5 years old, range 10-22 years old) suffering from dystrophic scoliosis associated with NF1 underwent posterior-only surgical correction using a MAPM. The apex of the deformity was thoracic (n = 25), thoracolumbar (n = 4), and lumbar (n = 2). The mean preoperative coronal Cobb angle was 69.1° (range 48.9°-91.4°). The mean Cobb angle on the side-bending radiograph of the convex side was 58.2° (range 40°-79.8°). The mean flexibility and apical vertebral rotation (AVR) were 15.6% (range 8.3%-28.2%) and 2.5° (range 2°-3°), respectively. The mean angle of sagittal kyphosis was 58.3° (range 34.1°-79.6°). RESULTS The mean follow-up period was 53 months (range 12-96 months). The mean postoperative coronal Cobb angle was 27.4° (range 16.3°-46.7°). Postoperatively, the mean AVR and angle of sagittal kyphosis were 1.2° (range 1°-2°) and 22.4° (range 4.2°-36.3°), respectively. All patients showed good correction of all indices postoperatively. The mean postoperative correction rate was 58.7% (range 46.3%-74.1%). At the final follow-up evaluation, the corrective loss rate of the Cobb angle was only 2.3%. Only 1 patient required revision surgery. No severe complications such as spinal cord, neural, or large vascular injury occurred during the operation. CONCLUSIONS Posterior-only surgical correction of dystrophic scoliosis in patients with NF1 using a MAPM could yield satisfactory clinical efficacy of correction and fusion.

    Full Text Available Aim. To compare the results of surgical correction of spinal deformity in children with idiopathic thoracic scoliosis with the use of transpedicular screw spinal systems with different pedicle screw placement. Material and methods. Thirty-one patients (14–17 years with spinal curvature with a Cobb angle from 40° to 79° were operated on. Surgical correction of the deformity was performed using two methods, depending on the possible placement of a pedicle screw. The first group included 16 patients for whom the transpedicular support elements were placed on both sides, throughout the completely deformed spine. The second group included 15 patients for whom the pedicle screws were not placed for two or more vertebrae on the concave side of the curve, at the top of the main curve. Results. The mean percent correction of the spinal deformity for the first and second groups was 92.5% and 82.6%, respectively. The mean percentage of derotation of the apical vertebra for the first and second groups was 73.9% and 23%, respectively. Conclusion. The use of data based on the anatomical and anthropometric features of the vertebral body with scoliosis facilitates selection of the best option for correction of thoracic curve in children with idiopathic scoliosis using pedicle multi-support metal construction. The use of the spinal pedicle system for correction of spinal deformity in children with idiopathic scoliosis enabled a uniform load distribution along the support elements of the metal construction and maintained the correction in the late postoperative follow-up period.

    Muhimbili National Hospital (MNH), a teaching and national referral hospital, is undergoing major reforms to improve the quality of health care. We performed a retrospective descriptive study using a set of performance indicators for the surgical and laboratory services of MNH in years 2001 and 2002, to help monitor and evaluate the impact of reforms on the quality of health care during and after the reform process. Hospital records were reviewed and information recorded for planned and postponed operations, laboratory equipment, reagents, laboratory tests and quality assurance programmes. In the year 2001 a total of 4332 non-emergency operations were planned, 3313 operations were performed and 1019 (23.5%) operations were postponed. In the year 2002, 4301 non-emergency operations were planned, 3046 were performed and 1255 (29%) were postponed. The most common reasons for operation postponement were "time-barred", interference by emergency operations, no show of patients and inoperable anaesthetic machines. Equipment problems and supply and staff shortages together accounted for one quarter of postponements. In the laboratory, a lack of equipment prevented some tests, but quality assurance was performed for most tests. Current surgical services at MNH are inadequate; operating theatres require modern, functioning equipment and adequate supplies of consumables to provide satisfactory care.

    Of 200 cases of CD observed in the course of twenty years, 141 (70.5%) have been treated by surgery. At the time of surgery, 6 patients had duodenitis, 87 ileitis, 35 ileocolitis, 9 colitis and 8 proctocolitis. In 4 cases the duodenum and ileum were simultaneously involved. Complications of the disease and failure of medical treatment represented the indications for surgery. Elective surgery was possible in 74.5% of cases. Intestinal resection was performed in all cases except for 6 by-passes (4 for duodenal obstruction) and 3 external derivations (1 ileostomy for perforation, and 2 colostomies: one for colovesical fistula and another for a rectovaginal fistula). Surgical strategy mainly depended on the site, number and extent of lesions, together with complications arising from them. Data from preoperative absorption tests and intraoperative measurements of the small bowel were useful aids in determining whether a resection was to be "radical" or "limited". Overall p.o. mortality was 4.2%. The follow-up (from 2 to 21 years) showed a long-term mortality rate of 5.7%. The rate of recurrences was 55.2%. However surgical management undeniably improved the quality of life, that was in fact good, or fairly good, even in the great majority (81.2%) of patients with recurrences.

Magnetic resonance imaging (MRI) revealed cerebellar crowding and compression consistent with Chiari-like malformation. The clinical signs did not improve after surgical occipital craniectomy, and 2 mo postoperatively a second MRI showed hydromyelia and continued cerebellar compression. The bobcat was euthanized, and necropsy showed chronic focal cerebellar herniation and chronic multifocal atlanto-occipital joint osteophyte proliferation. Histology confirmed the presence of a thick fibrous membrane along the caudal aspect of the cerebellar vermis, suggestive of postoperative adhesions, and axonal degeneration of the cervical spinal cord, even in sections without a central canal lesion. These lesions appear to have been complications associated with surgical correction of the Chiari-like malformation.

    Full Text Available Correction of skeletal deformities in adult patients with orthodontics is limited. Orthognathic surgery is the best option for cases when camouflage treatment is questionable and growth modulation is not possible. This case report illustrates the benefit of the team approach in correcting vertical maxillary excess along with class II skeletal deformity. A cosmetic correction was achieved by superior repositioning of maxilla with LeFort I osteotomy and augmentation genioplasty, along with orthodontic treatment. The patient′s facial appearance was markedly improved along with functional and stable occlusion

    Equinovarus foot deformity (EVFD) compromises several prerequisites of walking and increases the risk of falling. Guidelines on rehabilitation following EVFD surgery are missing in current literature. The aim of this study was to analyze safety and adherence to an early rehabilitation treatment characterized by immediate weight bearing with an ankle-foot orthosis (AFO) in hemiplegic patients after EVFD surgery and to describe gait changes after EVFD surgical correction combined with early rehabilitation treatment. Retrospective observational cohort study. Inpatient rehabilitation clinic. Forty-seven adult patients with hemiplegia consequent to ischemic or haemorrhagic stroke (L/R 20/27, age 56±15 years, time from lesion 6±5 years). A specific rehabilitation protocol with a non-articulated AFO, used to allow for immediate gait training, started one day after EVFD surgery. Gait analysis (GA) data before and one month after surgery were analyzed. The presence of differences in GA space-time parameters, in ankle dorsiflexion (DF) values and peaks at initial contact (DF at IC), during stance (DF at St) and swing (DF at Sw) were assessed by the Wilcoxon Test while the presence of correlations between pre- and post-operative values by Spearman's correlation coefficient. All patients completed the rehabilitation protocol and no clinical complications occurred in the sample. Ankle DF increased one month after surgery at all investigated gait phases (Wilcoxon Test, Prehabilitation associated with surgical procedure is safe and may be suitable to correct EVFD by restoring both the neutral heel foot-ground contact and the ankle DF peaks during stance and swing at one month from surgery. The proposed protocol is a safe and potentially useful rehabilitative approach after EVFD surgical correction in stroke patients.

    Full Text Available This study examines the foremost concerns related to most noted research performance index. The most popular and widely acceptable h-index underestimates the highly visible scientist, the middle order group, due to citation distribution issues. The study addresses this issue and uses 'Corrected Quality Ratio' (CQ to check the implicit underpinnings as evident in h-index. CQ helps to incorporate the aspects of a good research performance indicator. This simple revision performs more intimately and logically to gauge the broader research impact for all groups and highly visible scientists with less statistical error.

    In order to evaluate the usefulness in deciding surgical indication in secondary hyperparathyroidism (SHP), {sup 67}Ga scintigraphy was performed in 37 patients of SHP before parathyroidectomy (PTx). The radionuclide accumulation in skull and submandible was classified into 4 patterns (skull-submandibular pattern, skull pattern, submandibular pattern and normal pattern). Serum alkaline phosphatase levels were significantly elevated in patients of skull-submandibular pattern (13 cases) compared with skull pattern (6 cases), submandibular pattern (6 cases) and normal pattern (12 cases). Serum intact parathyroid hormone levels were significantly elevated in patients of skull-submandibular and skull patterns compared with normal pattern. No significant difference was observed among the weight of resected parathyroid glands. In 4 of 6 patients of normal pattern on {sup 67}Ga scintigram, bone scintigraphy showed a characteristic pattern of SHP including an increased accumulation in the skull and submandible. Bone mineral density (BMD) in the distal radius was increased within six to twelve months after PTx in 10 of 11 patients of skull-submandibular pattern on {sup 67}Ga scintigram, whereas only one patient showed an increase in BMD in 9 patients of normal pattern. In summary, it was concluded that {sup 67}Ga scintigraphy could provide a useful information in deciding the indication for PTx in secondary hyperparathyroidism. (author)

    Full Text Available Study Design. Quasiexperimental study. Objective. To investigate whether radiofrequency treatment can preclude the need for spinal surgery in both the short term and long term. Background. Radiofrequency is commonly used to treat lumbosacral radicular pain. Only few studies have evaluated its effects on surgical indications. Methods. We conducted a quasiexperimental study of 43 patients who had been scheduled for spinal surgery. Radiofrequency was indicated for 25 patients. The primary endpoint was the decision of the patient to reject spinal surgery 1 month and 1 year after treatment (pulsed radiofrequency of dorsal root ganglion, 76%; conventional radiofrequency of the medial branch, 12%; combined technique, 12%. The primary endpoint was the decision of the patient to reject spinal surgery 1 month and 1 year after treatment. In addition, we also evaluated adverse effects, ODI, NRS. Results. We observed after treatment with radiofrequency 80% of patients rejected spinal surgery in the short term and 76% in the long term. We conclude that radiofrequency is a useful treatment strategy that can achieve very similar outcomes to spinal surgery. Patients also reported a very high level of satisfaction (84% satisfied/very satisfied. We also found that optimization of the electrical parameters of the radiofrequency improved the outcome of this technique.

    Fifteen cases of jaw-winking blepharoptosis treated, are reported, to suggest the management of the surgical methods. The degree of the ptosis, the eyelid retraction, the surgical procedures are reviewed. Patients with a wild retraction required a levator muscle resection. Patients with a moderate or severe retraction required an unilateral levator denervation with frontalis suspension. In this case, the most satisfactory surgical results were obtained with unilateral levator denervation on the affected side compared with a bilateral frontalis suspension with fresh autogenous fascia. Then, the surgical procedure seems to depend especially on the eyelid retraction.

    A retrospective study. The aim of this study was to investigate the correlation between pelvic incidence (PI) and lumbar lordosis (LL) mismatch and knee flexion during standing in patients with lumbar degenerative diseases and to examine the effects of surgical correction of the PI-LL mismatch on knee flexion. Only several studies focused on knee flexion as a compensatory mechanism of the PI-LL mismatch. Little information is currently available on the effects of lumbar correction on knee flexion in patients with the PI-LL mismatch. A group of patients with lumbar degenerative diseases were divided into PI-LL match group (PI-LL ≤ 10°) and PI-LL mismatch group (PI-LL > 10°). A series of radiographic parameters and knee flexion angle (KFA) were compared between the two groups. The PI-LL mismatch group was further subdivided into operative and nonoperative group. The changes in KFA with PI-LL were examined. The PI-LL mismatch group exhibited significantly greater sagittal vertical axis (SVA), pelvic tilt (PT) and KFA, and smaller LL, thoracic kyphosis (TK), and sacral slope than the PI-LL match group. PI-LL, LL, PI, SVA, and PT were significantly correlated with KFA in the PI-LL mismatch group. From baseline to 6-month follow-up, all variables were significantly different in the operative group with the exception of PI, although there was no significant difference in any variable in the nonoperative group. The magnitude of surgical correction in the PI-LL mismatch was significantly correlated with the degree of spontaneous changes in KFA, PT, and TK. The PI-LL mismatch would contribute to compensatory knee flexion during standing in patients with lumbar degenerative disease. Surgical correction of the PI-LL mismatch could lead to a spontaneous improvement of compensatory knee flexion. The degree of improvement in knee flexion depends in part on the amount of correction in the PI-LL mismatch. 3.

  13. Power spectra and spectral indices of $k$-inflation: high-order corrections

    $k$-inflation represents the most general single-field inflation, in which the perturbations usually obey an equation of motion with a time-dependent sound speed. In this paper, we study the observational predictions of the $k$-inflation by using the high-order uniform asymptotic approximation method. We calculate explicitly the slow-roll expressions of the power spectra, spectral indices, and running of the spectral indices for both the scalar and tensor perturbations. These expressions are all written in terms of the Hubble and sound speed flow parameters. It is shown that the previous results obtained by using the first-order approximation have been significantly improved by the high-order corrections of the approximations. Furthermore, we also check our results by comparing them with the ones obtained by other approximation methods, including the Green's function method, WKB approximation, and improved WKB approximation, and find the relative errors.

  14. Surgically induced astigmatism after phacoemulsification with and without correction for posture-related ocular cyclotorsion: randomized controlled study.

    2012-02-01

    PURPOSE: To report the impact of posture-related ocular cyclotorsion on one surgeon\\'s surgically induced astigmatism (SIA) results and the variance in SIA. SETTING: Institute of Eye Surgery, Whitfield Clinic, Waterford, Ireland. METHODS: This prospective randomized controlled study included eyes that had phacoemulsification with intraocular lens implantation. Eyes were randomly assigned to have (intervention group) or not have (control group) correction for posture-related ocular cyclotorsion. In the intervention group, the clear corneal incision was placed precisely at the 120-degree meridian with instruments designed to correct posture-related ocular cyclotorsion. In the control group, the surgeon endeavored to place the incision at the 120-degree meridian, but without markings. RESULTS: The intervention group comprised 41 eyes and the control group, 61 eyes. The mean absolute SIA was 0.74 diopters (D) in the intervention group and 0.78 D in the control group; the difference between groups was not statistically significant (P>.5, unpaired 2-tailed Student t test). The variance in SIA was 0.29 D(2) and 0.31 D(2), respectively; the difference between groups was not statistically significant (P>.5, unpaired F test). CONCLUSIONS: Attempts to correct for posture-related ocular cyclotorsion did not influence SIA or its variance in a single-surgeon series. These results should be interpreted with full appreciation of the limitations of currently available techniques to correct for posture-related ocular cyclotorsion in the clinical setting.

    OBJECT Craniosynostosis is a condition in which one or more of the calvarial sutures fuses prematurely. In addition to the cosmetic ramifications attributable to premature suture fusion, aberrations in neurophysiological parameters are seen, which may result in more significant damage. This work examines the microstructural integrity of white matter, using diffusion tensor imaging (DTI) in a homogeneous strain of rabbits with simple, familial coronal suture synostosis before and after surgical correction. METHODS After diagnosis, rabbits were assigned to different groups: wild-type (WT), rabbits with early-onset complete fusion of the coronal suture (BC), and rabbits that had undergone surgical correction with suturectomy (BC-SU) at 10 days of age. Fixed rabbit heads were imaged at 12,25, or 42 days of life using a 4.7-T, 40-cm bore Avance scanner with a 7.2-cm radiofrequency coil. For DTI, a 3D spin echo sequence was used with a diffusion gradient (b = 2000 sec/mm2) applied in 6 directions. RESULTS As age increased from 12 to 42 days, the DTI differences between WT and BC groups became more pronounced (p days and 100% accurate at 42 days). CONCLUSIONS Craniosynostosis results in characteristic changes of major white matter tracts, with differences becoming more apparent as the age of the rabbits increases. Early suturectomy (at 10 days of life) appears to mitigate these differences. PMID:25929965

    Many benign and malignant tumors as well as other inflammatory or vascular diseases may be located in the areas of Meckel's cave or the cavernous sinus. Except for typical features such as for meningiomas, imaging may not by itself be sufficient to choose the best therapeutic option. Thus, even though modern therapy (chemotherapy, radiotherapy, or radiosurgery) dramatically reduces the field of surgery in this challenging location, there is still some place for surgical biopsy or tumor removal in selected cases. Until recently, the microscopic subtemporal extradural approach with or without orbitozygomatic removal was classically used to approach Meckel's cave but with a non-negligible morbidity. Percutaneous biopsy using the Hartel technique has been developed for biopsy of such tumors but may fail in the case of firm tumors, and additionally it is not appropriate for anterior parasellar tumors. With the development of endoscopy, the endonasal route now represents an interesting alternative approach to Meckel's cave as well as the cavernous sinus. Through our experience, we describe the modus operandi and discuss what should be the appropriate indication of the use of the endonasal endoscopic approach for Meckel's cave disease in the armamentarium of the skull base surgeon.

    Pseudoaneurysm formation often complicates transfemoral interventional procedures. Nonsurgical treatment consists of femoral compression and thrombin injection under ultrasound guidance. We report a 74-year-old man who was diagnosed with a pseudoaneurysm, following coronary angiography. Duplex ultrasound revealed deep vein thrombosis of the ipsilateral common femoral vein. Ultrasound-guided thrombin injection was unsuccessfully performed, and the patient subsequently underwent surgical exploration for repair of the pseudoaneurysm and release of the venous compression. The increased local inflammation, because of the thrombosis, added in surgical difficulties. We conclude that early surgical intervention should be considered as a primary strategy in patients with femoral pseudoaneurysms and deep vein thrombosis secondary to femoral compression.

    Orthognathic surgery is undergone to improve facial and dental aesthetics and to improve function. Three dimensional (3D) soft tissue analysis based on stereophotogrammetry provides a realistic measurement of facial morphology. There is a need for objective assessment of surgery outcomes. The study aim was to evaluate the 3D naso-maxillary complex soft tissue morphology following Le Fort I maxillary advancement and compare the findings with a local reference group. 3D images of 112 volunteers were captured using stereophotogrammetry and viewed by 8 lay people; 40 images (16 males and 24 females) were chosen as the reference group to have harmonious facial appearance. The linear and angular measurements of this group were compared with 35 patients (19 female and 16 male) who had maxillary advancement in the post-surgical group. Facial morphology post-surgery was similar to the reference group, except the nasal base width which was wider by 2.3mm in males and 2.6mm in females. In the orthognathic group, the females had a smaller nasolabial angle by 9.7° than the reference group. In conclusion, 3D imaging is a sensitive tool for analysing facial appearance. Compared with a control group, statistical differences were identified in soft tissue morphology which should be considered in surgical planning and patient consent.

    Camptocormia or 'bent spine syndrome' is a rare manifestation of Parkinson's disease. The postural deformity can be a great source of disability. Camptocormia is typically not responsive to dopaminergic medication. Results with deep brain stimulation to treat camptocormia have been mixed but generally poor. The authors report two cases of camptocormia in Parkinson's disease treated with spinal corrective surgery. Despite prolonged postoperative courses, including a high complication rate and the need for multiple revisions, both patients benefited from the procedures.

    For the patient (and the surgeon) the ideal wrist is one that has good mobility, however very often the optimal surgical treatment is one that provides effective pain relief. The patient must be informed of the potential complications and limitations of each procedure. The patient's psychological profile and functional requirements will determine how well he/she adapts to the changes. Also, each surgeon has beliefs and personal experiences that influence the treatment decision and final result. Proximal row carpectomy (PRC) and the Watson procedure are two reference operations for osteoarthritis secondary to scapholunate instability and scaphoid non-union (SLAC and SNAC). Beyond the early complications and drawbacks specific to each, they provide good results that are maintained over time. PRC, which can be performed up to Stage II, is mainly indicated in patients with moderate functional demands, while the Watson procedure is more often done on a patient who performs manual labour, as long as the radiolunate joint space is maintained. Complete denervation is effective in three out of four cases and preserves the remaining mobility. Because of its low morbidity, the procedure can be suggested in patients with a mobile wrist and low functional demands or in older patients, independent of their wrist mobility. Total wrist fusion is not only a rescue procedure. For a young patient who performs heavy manual labour with extensive osteoarthritis and progressive forms of Kienböck's disease, this procedure provides the greatest chance of returning to work and not being socially outcast. The role of osteochondral autografts, implants and wrist prostheses in the treatment arsenal need to be better defined.

    Benign pancreatic tumors should undergo surgical resection when they are symptomatic or - in the case of incidental discovery - bear malignant potential. This is the case for the majority of benign pancreatic tumors, especially for intraductal papillary mucinous neoplasms or mucinous cystic adenomas. In addition, resection is indicated for all tumors where preoperative diagnostic fails to provide an exact classification. Several different operative techniques are available. The treatment of choice depends on the localization of the tumor, its size and on whether there is evidence of malignant transformation. Partial duodenopancreatectomy is the oncological treatment of choice for tumors of the pancreatic head whereas for tumors of the pancreatic tail a left-sided pancreatectomy is appropriate. Middle pancreatectomy or duodenum-preserving resection of the pancreatic head is not a radical oncologic procedure. They should only be performed in cases of tumors without malignant potential. (orig.) [German] Die Indikationsstellung zur Resektion benigner Pankreastumoren ist gegeben, wenn es sich um einen symptomatischen Tumor handelt oder - bei einem Zufallsbefund - um einen Tumor mit Potenzial zur malignen Entartung. Dies besteht bei der Mehrzahl der benignen Pankreastumoren, insbesondere bei der intraduktalen papillaeren muzinoesen Neoplasie (IPMN) oder muzinoesen Zystadenomen. Operativer Abklaerung beduerfen auch Tumoren, die unter Ausschoepfung aller diagnostischer Moeglichkeiten nicht eindeutig klassifizierbar sind. An chirurgischen Therapieverfahren stehen verschiedene Techniken zur Verfuegung. Die Wahl des Verfahren haengt von der Groesse und Lokalisation des Tumors ab und von der Frage, ob eine maligne Entartung bereits stattgefunden hat. Das onkologisch korrekte Standardresektionsverfahren bei Tumoren des Pankreaskopfes ist die partielle Duodenopankreatektomie, bei Tumoren des Pankreasschwanzes die Pankreaslinksresektion.

    Full Text Available In this paper we analyze the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use the long-slit spectra of the elliptical galaxy IC 1459 from which its kinematics had previously been extracted to calculate the Lick indices for the observed spectral region (Mg2, Fe5270, Fe5335 and Hβ. We apply the usual procedure and correct the indices to the Lick spectral resolution and for the zero velocity dispersion. The procedure applied in this paper also corrects to non-Gaussian line-of-sight velocity distribution (LOSVD observed in this galaxy, especially in its outer parts. The findings of Kuntschner (2004 were tested and it is shown that the departures from the Gaussian LOSVD may indeed cause erroneous determinations of the Lick indices. The impact of the introduction of non-Gaussian LOSVD differs for different indices. For the galaxy IC 1459 it is shown that the iron indices are especially sensitive when the correction due to anistropies is introduced: the corrections for Fe5270 and Fe5335 are ~10 and ~19 percent larger, respectively, than the corrections obtained in case of a pure Gaussian. The corrections for Mg2 index are shown to be negligible and the corrections of the Hβ index due to anisotropies are also small (below ~ 4 per cent at most.

    Full Text Available Purpose. In recent years, endoscopic injection became the procedure of choice for the correction of vesicoureteral reflux in the majority of the centers. Unfortunately, endoscopic treatment is not always successful and sometimes requires more than one trial to achieve similar results to that of an open reimplantation surgery. Our aim of this study is to evaluate the feasibility and success rate of open ureteral reimplantation following failed endoscopic procedure. Patients and Methods. During 2004–2010, we evaluated 16 patients with persistent vesicoureteral reflux (grades II–IV following failed endoscopic treatment. All patients underwent open ureteral reimplantation. All patients were followed with an ultrasound 6 weeks following surgery and every 6 months thereafter for an average of 22 months. Voiding cystography was performed at 3 months after surgery. Results. During unilateral open ureteral reimplantation, the implanted deposit from previous procedures was either excised, drained, or incorporated into the neotunnel with the ureter. Vesicoureteral reflux was resolved in all patients with 100% success rate. No new hydronephrosis or signs of obstruction developed in any of the patients. qDMSA renal scan was available in 8 patients showing improvement of function in 5 and stable function in 3, and no new scars were identified. Conclusions. Open ureteral reimplantation is an excellent choice for the correction of failed endoscopic treatment in children with vesicoureteral reflux.

    We studied 24 patients with pure and severe aortic regurgitation. Using 2-D Echocardiography we obtained parasternal short axis view and calculate the thickness/radio (H/r) ratio and with apical four chambers and two chambers view the ejection fraction (E.F.) with biplanar Simpson technic. The patients were divided in three groups: I) those (12) with E.F. and H/r ratio within normal limits; II) those (6) with low H/r ratio and normal E.F. and the third group III) was formed with 6 patients whom had low H/r ratio and E.F. Three patients from group I had surgical treatment without mortality; all but one (bacterial endocarditis) are alive after two years; five patients from group II had surgical treatment and everyone is alive in functional class I in the same period. All patients of the third group III but one (that had surgical treatment) are death in spite of medical treatment. We conclude that the optimal moment for surgical procedure in severe aortic regurgitation can be determined when the hypertrophy does not compensate the hemodynamic overload (decreases H/r) but the cardiac performance (E.F.) is normal. In this moment the surgical mortality is low and the procedure can change the natural history of the disease.

Exclusion criteria were: age less than 1 year or more than 3 years, presence of confirmed heart rhythm disturbances before surgery except incomplete or complete right bundle branch block in presence of right ventricular myocardial hypertrophy, left anterior bundle branch block in presence of partial or complete atrioventricular canal defect and sinus tachycardia equal to circulatory failure (CF. Results. Ventricular arrhythmias such as premature ventricular contraction (PVC of different character were frequently seen in early postoperative period after surgical correction of CHD. They were noted in 36% of overall number postoperative arrhythmias. Supraventricular extrasystole occurred in 29% cases, different types of supraventricular tachycardias – in 17%, AV-blocks of different grades – in 10%. We noted the following predictors for postoperative rhythm disturbance development: age more than 25 months at the moment of surgery, prolonged CPB and aortic cross-clamping during ventricular septal defect (VSD (70 and 39 minutes, respectively and Fallot’s tetralogy correction (100 and 60 minutes, respectively and exceeding the critical end-point of aortic cross-clamping during atrial septal defect correction (ASD (24 minutes, presence of IIA and IIb grade for CF before surgery, surgical correction of ASD under hypothermia of less than 32 °C. Exceeding the critical end-points of CPB and aortic clamping in patients with Fallot’s tetralogy and exceeding the critical end-points of aortic clamping in children with VSD and ASD were shown to be the

    Surgical restoration of accommodation with accommodating intra-ocular lenses (A-IOLs) presents a complex set of problems involving the design of the prosthetic mechanism. A variety of designs are currently employed that either translate the A-IOL toward the cornea along the sagittal axis, shear two lens components laterally, or deform lens shape to change dioptric power of the eye during attempts to accommodate. Effective biomechanical properties (elasticity and viscosity) of these lenses depend on both material properties and structural design of the A-IOL. Inevitable mismatches between the neuromuscular control of accommodation and the effective biomechanical properties of the prosthetic lens could lead to either unstable oscillations or sluggishness of dynamic accommodation; however, optimal dynamic responses may possibly be restored by neural recalibration. A model of dynamic accommodation is used to predict the consequences of these mismatches on dynamic accommodation, and reverse engineering is used to test the feasibility of neuromuscular recalibration. Empirical measures verify that neuromuscular adaptation of dynamic accommodation is possible in response to optically simulated increases and decreases of ocular-lens stiffness. Other design issues for A-IOLs include stability of optical properties, aberrations and image quality, and interactions of restored accommodation with binocular eye alignment (the near response).

    The objective of this study was to compare the inflammatory response within the abdominal cavity between three surgical methods. The study comprised 45 cows with left displacement of the abomasum, which were allocated into three groups (n = 15). Right flank laparotomy and omentopexy (group R), left flank laparotomy and omentopexy (group L), and laparoscopic abomasopexy (group J) have been applied. Laparoscopic abomasopexy was the only technique that requires perforation of the abomasal wall. Blood and peritoneal fluid (PF) samples were obtained before, and on days 1, 2 and 3 after surgery. Macroscopic and microscopic evaluation of PF were performed. Cytological and biochemical parameters were analysed in blood and PF. No bacteria were present in PF after surgery. The number of PF leukocytes increased in all groups on day 1 after surgery with the highest value after laparoscopy (median, 1st quartile, 3rd quartile, R: 13.1, 6.4, 16.0; L: 13.6, 9.9, 17.4; J: 33.7, 21.1, 46.9 G/l). Laparotomy resulted in an increase of blood and PF CK on day 1 after surgery, whereas, laparoscopy caused an increased PF CK only. All groups had elevated PF D-dimer concentrations before surgery, with further increase in groups R and L on day 1 after surgery.

    25 patients (normotensive n = 19, hypertensive n = 6) underwent DSA control following corrective surgery of a coarcatation of the thoracic aorta to exclude vascular complications. Simultaneously pressure gradients were determined between upper and lower extremities using the doppler-sonography. DSA was diagnostic in all patients. 2 cases showed a patch-dependent dilatation, in 1 case an anastomotic aneurysm could be demonstrated. In 6 patients with hypoplastic aortic arch and 2 patients with a slight reduction of the diameter in the anastomotic region a pathological pressure-gradient was measured. In these patients the ratio of aortic arch rsp. anastomosis/descending aorta was reduced in diameter (< 0,66) and area (< 44). Hypertension could not be related to pressure gradients or vascular disorders.

    The growth of the unit of vertebrae and intact vertebrae outside and within the instrumental fixation area was studied in children operated on for tuberculosis spondylitis complicated by severe kyphotic deformity. There was a considerable growth retardation of blocked vertebrae after radical spinal repair from the growth of intact vertebrae. Instrumental fixation of the vertebral column after its radical reconstruction causes no considerable retardation of the vertical growth of intact vertebral bodies; however, it leads to the advanced growth of their anterior versus posterior portions, which mediates a supplementary self-correction of residual kyphosis during growth. When compression implants are presented in the body for 2 years or more, most children develop degeneration of intervertebral risks within the fixation area.

    Full Text Available Valence topological charge-transfer (CT indices are applied to the calculationof dipole moments μ. The μ calculated by algebraic and vector semisums of the CTindices are defined. The model is generalized for molecules with heteroatoms andcorrected for sp3-heteromolecules. The ability of the indices for the description of themolecular charge distribution is established by comparing them with μ of the valence-isoelectronic series of cyclopentadiene, benzene and styrene. Two CT indices, μvec(vector semisum of vertex-pair μ and μvecV (valence μvec are proposed. The μvecVbehaviour is intermediate between μvec and μexperiment. The correction is produced in thecorrect direction. The best results are obtained for the greatest group. Inclusion of theheteroatom in the π-electron system is beneficial for the description of μ, owing to eitherthe role of additional p and/or d orbitals provided by the heteroatom or the role of stericfactors in the π-electron conjugation. The steric effect is almost constant along the seriesand the dominating effect is electronic. Inclusion of the heteroatom enhances μ, whichcan improve the solubility of the molecule. For heteroatoms in the same group, the ringsize and the degree of ring flattering are inversely proportional to their electronegativity.

    Full Text Available The goal of this article is to estimate the androgenic status and analyze its influence on the surgical treatment of hypospadias. From 2000 till 2008 there were 209 children under treatment, whose age varied from 8 months till 15 years old (average age — 4,5+ 1,5. 49 patients were subjected to clinical, humoral and morphological study. Preoperational preparation was carried out by testosterone medications. The comparison group consisted of 10 boys with cicatricial phimosis. The patients with the medium and back forms of hypospadias suffered from the androgenic deficit characterized by proximal level of meatus ectopia, diminution of penis length and prostate volume, decrease of blood vessels in deep layers of penis skin. The testosterone pre-operational medication of patients makes possible to improve the results of surgical correction due to blood supply of plastic material. On the basis of recieved data logistically regressive model has been worked out and the prognosis of results has been estimated

    Ectopic penis is usually associated with penoscrotal transposition, and it is rarely observed in isolation. We report a surgical approach for an extremely rare case. A 10-year-old male patient with bilateral cryptorchidism and ectopic penis and scrotum in perineal area, with no penoscrotal transposition, representing an association not yet described in literature. A previous orchiopexy failed due to ectopic scrotum. By means of an inverted Y incision, the penis was mobilized and a perineal skin flap in form of a testicular sac was prepared. Finally orchiopexy was performed. The surgery was essential to treat cryptorchidism and to improve the self-image of the patient. RESUMO O pênis ectópico geralmente ocorre associado à transposição peno-escrotal, sendo raro isoladamente. Relatamos uma abordagem cirúrgica para um caso extremamente raro. Tratava-se de paciente do sexo masculino, 10 anos, com criptorquidia bilateral e pênis e escroto ectópicos, na região perineal, sem transposição peno-escrotal, representando uma associação ainda não descrita na literatura. Orquidopexia prévia sem sucesso, devido à ectopia do escroto. Por meio de uma incisão em Y invertido, mobilizou-se o pênis e preparou-se um retalho da pele perineal em forma de bolsa testicular. Por fim, realizou-se a orquidopexia. A cirurgia foi fundamental para tratar a criptorquidia e promover ganho na autoimagem do paciente.

    The purpose of the present study is to present the surgical technique for, and review our indications and results after, endoscopic fascial release in patients with plantar fasciitis. In five thiel-embalmed human specimens, a biportal technique for endoscopic release of the plantar fascia was established. The aim was here to evaluate the relation between the plantar fascia and the heel spur and to perform a release that would not exceed 50-70% of the diameter of the calcaneoplantar fascia. The endoscopic technique was performed within the last 5 years in ten male and seven female patients. All patients with the clinical entity of plantar fasciitis underwent conservative treatment for at least 6 months. The average age at surgery was 35 years (24-56 years). In the first five patients, surgery was performed under c-arm control. In all patients the operation could be finished endoscopically. The endoscopic portals healed without complications. The time for surgery during the learning curve ranged between 21 and 74 min (average 41 min) and was still longer compared to the open technique. The clinical follow-up ranged between 4 and 48 months (average 18.5 months). Out of 17 patients, 13 improved clinically, and they would choose the treatment option again. In the Ogilvie-Harris score, seven patients showed good and six excellent results. In two patients, the initial results were not satisfactory, because of a bony stress reaction of the calcaneus. This complication was treated by 6 weeks of partial weight bearing, without any further problems. Two other patients developed secondary pain in the lateral column. In spite of the minimal invasive approach it seems to be important to be careful in increasing the weight bearing in early rehabilitation. The technique of the endoscopic plantar fascia release (E FRPF) can be performed in a standardised and reproducible procedure. The follow-up examination showed good midterm results, but a loss of stability of the plantar arch

    This study aims at verifying if impaired sensorimotor control observed in adolescents and young adults with scoliosis is also present in adult patients who underwent surgery to reduce their spine deformation. The study included ten healthy adults and ten adults with idiopathic scoliosis who underwent surgery to reduce their spine deformation. Galvanic vestibular stimulation was delivered to assess sensorimotor control. Vertical forces under each foot and horizontal displacement of the upper body were measured before, during and after stimulation. Balance control was assessed by calculating the root mean square values of kinematic and kinetic variables. The amplitude of the vestibular-evoked postural response was 3.4 % (0.8-6.0 %) and 4.5 % (-0.4 to 9.5 %) of the maximal range of motion. Therefore, spine surgery did not limit the postural response. Patients with idiopathic scoliosis exhibited larger body sway than the healthy controls during and immediately after vestibular stimulation. The maximal normalized lateral displacement of the body was 0.85 and 0.40 cm/m and maximal normalized vertical force was 0.78 vs. 0.39 N/kg, for idiopathic scoliosis and healthy groups, respectively. This result suggests that dysfunctional sensorimotor integration is still present even in adult idiopathic scoliosis that underwent spine deformation correction.

    Postoperative anorectal malformation patients frequently have defecatory dysfunction. MRI may be useful in the management of these patients. To analyze static and dynamic MRI findings in patients with defecatory dysfunction after correction of anorectal malformation (ARM), and compare differences between patients with constipation and fecal incontinence. Pelvic MRI studies of 20 constipated and 32 incontinent postoperative ARM patients were analyzed retrospectively to determine the location and morphology of the neorectum, presence of peritoneal fat herniation, presence of scarring, development of the striated muscle complex (SMC) and any other abnormalities. The two groups were then compared using {chi} {sup 2}-test. Eighteen patients also underwent MRI defecography to evaluate pelvic floor function and abnormalities are reported. The children with incontinence were more likely to have abnormal location of the neorectum (P = 0.031), increased anorectal angle (ARA) (P = 0.031) and peritoneal fat herniation (P = 0.032), and less likely to have dilation of the neorectum (P = 0.027), than the children with constipation. There were no significant differences between the two groups in incidence of focal stenosis of the neorectum (P = 0.797), presence of extensive scarring (P = 0.591) and developmental agenesis of the SMC (P > 0.05). MRI defecography showed 6 anterior rectoceles, 6 cystoceles and 18 pelvic floor descents. MRI is a helpful imaging modality in postoperative ARM patients with defecatory dysfunction, and it shows distinct differences between the children with constipation and incontinence and provides individualized information to guide further treatment.

Materials and methods. 5 patients, heart valve replacement was performed with a func- tioning kidney transplant at a satisfactory its function. The average age of patients at the time of cardiac surgery was 38,8 ± 12,6 years, among whom were two (40% men and 3 (60% women. The interval between renal transplantation and heart surgery was 40,3 ± 44,1 (2 to 120 months. Prior to kidney transplantation, all patients were on renal replacement therapy with hemodialysis program for 50,2 ± 48,6 months. In 4 of the 5 patients of heart disease was the cause of infective endocarditis. Results. Average time IR was 81,2 ± 21,7 minutes , the average time of aortic clamping 63,6 ± 20,9 minutes and hypothermia during CPB 29,2 ± 3,2 °C. All patients were implanted with double-leaf mechanical prostheses "MedEng-2" and "SarboMedics". All 5 patients in sa- tisfactory condition were discharged from the hospital. The average duration of the postoperative period was 14,2 ± 3,4 days. All patients had relatively smooth flow after surgery, no infectious complications, a satisfactory renal transplant function and prosthetic heart valves. In the late period in four patients and transplant graft func- tion is satisfactory in terms of the observation of 5 years, 3 years and 6 months after surgery. Conclusion. Our experience shows the possibility of successful correction of heart defects in IR in renal transplant recipients.

    Arthrodesis is the most reliable and durable surgical procedure for the treatment of a joint disorder, with the main disadvantage of loss of motion of the fused joint. The distal radioulnar joint can be arthrodesed, while forearm pronation and supination are maintained or even improved by creating a pseudoarthrosis of the ulna just proximal to the arthrodesis. This is known as the Sauvé-Kapandji procedure. This procedure is not void of possible complications, such as nonunion or delayed union of the arthrodesis, fibrous or osseous union at the pseudoarthrosis, and painful instability at the proximal ulna stump. All of these can be prevented if a careful surgical technique is used. Copyright © 2010 Elsevier Inc. All rights reserved.

    To retrospectively review the clinical, radiological and pathological data in patients who underwent surgical resection for pulmonary pleomorphic carcinoma (PC), and to analyse the prognostic predictors of survival. The data were retrospectively examined for 33 consecutive patients (28 males and five females) who had undergone surgical resection for pulmonary PC. Cox's proportional-hazards model was used to analyse the prognostic predictors of survival. The size of the tumours ranged from 1.1 to 12.0 cm (mean 5.4 cm). The majority (26) of the tumours were located at the lung periphery, five tumours had cavitation, two had calcification and 14 had peritumoral ground-glass opacity. Most of the tumours showed heterogeneous enhancement and contained a low-density area (LDA) within the tumour. The 5-year overall survival of surgically resected PC was 36 % (standard error = 0.093). A multivariate analysis revealed the LDA grade [hazard ratio (HR), 2.019], pathological stage (HR, 7.552) and pathological N factor (HR, 0.370) to be significant predictors of a poorer prognosis. A greater component of LDA within the tumour on contrast-enhanced CT is associated with a poorer prognosis in patients with PC. (orig.)

    The Acute Surgical Unit (ASU) is a recent change in management of acute general surgical patients in hospitals worldwide. In contrast to traditional management of acute surgical presentations by a rotating on-call system, ASUs are shown to deliver improved efficiency and patient outcomes. This study investigated the impact of an ASU on operative management of appendicitis, the most common acute surgical presentation, by comparing performance indicators and patient outcomes prior to and after introduction of an ASU at the Gold Coast Hospital, Queensland, Australia. A retrospective study of patients admitted from the Emergency Department (ED) and who underwent emergency appendectomy from February 2010 to January 2011 (pre-ASU) and after introduction of the ASU from February 2011 to January 2012 (post-ASU). A total of 548 patients underwent appendectomy between February 2010 and January 2012, comprising 247 pre-ASU and 301 post-ASU patients. Significant improvements were demonstrated: reduced time to surgical review, fewer complications arising from operations commencing during ASU in-hours, and more appendectomies performed during the daytime attended by the consultant. There was no significant difference in total cost of admission or total admission length of stay. This study demonstrated that ASUs have potential to significantly improve the outcomes for operative management of acute appendicitis compared to the traditional on-call model. The impact of the ASU was limited by access to theaters and restricted ASU operation hours. Further investigation of site-specific determinants could be beneficial to optimize this new model of acute surgical care.

    Full Text Available In this paper we analyse the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use thelong-slit spectra of the elliptical galaxy IC 1459 from which its kinematicshad previously been extracted to calculate the Lick indices forthe observed spectral region (Mg$_2$, Fe5270, Fe5335 and H$_beta$. Weapply the usual procedure and correct the indices to the Lick spectralresolution and for the zero velocity dispersion. The procedure applied in thispaper also corrects to non-Gaussian line-of-sight velocity distribution(LOSVD observed in this galaxy, especially in its outer parts. The findingsof Kuntschner (2004 were tested and it is shown that the departures from theGaussian LOSVD may indeed cause erroneous determinations of the Lick indices. The impact of the introduction of non-Gaussian LOSVD differs for differentindices. For the galaxy IC~1459 it is shown that the iron indices areespecially sensitive when the correction due to anistropies is introduced: thecorrections for Fe5270 and Fe5335 are $sim 10$ and $sim 19$ percentlarger, respectively, than the corrections obtained in case of a pure Gaussian. The corrections for Mg$_2$ index are shown to be negligible and thecorrections of the H$_beta$ index due to anisotropies are also small (below$sim 4$ per cent at most.

    Full Text Available Snakebite is a particularly important health problem in rural areas of tropical regions. A large number of victims survive with permanent physical sequelae due to local tissue necrosis. However, necrosis may be associated with compartment syndrome especially when the bite is on the hands or feet. Herein, we describe two cases reported at a rural district hospital in Central African Republic. The present study suggests that active multidisciplinary management may improve patient prognosis while evidencing how difficult it is to decide on surgical intervention.

    Negative upper airway pressure is thought to play a key role in the pathophysiology of obstructive sleep apnea. Because nasal resistance contributes to the increase of the transpharyngeal pressure gradient, we evaluated the effects of nasal surgery on sleep-related breathing abnormalities in 20 adults with obstructive sleep apnea. Polysomnographic studies were done before (baseline), and 2 to 3 mo after surgery (septoplasty, turbinectomy, and/or polypectomy). Nasal resistances were measured at these visits in 14 patients. Cephalometric measurements were obtained before surgery. Cephalometric abnormalities consisted in an increase in the distance from the mandibular plane to the hyoid bone (MP-H), a decrease in the space between the base of the tongue and the posterior soft tissues (PAS), a retroposition of the mandibule, and an increase in the length of the soft palate. Body weight did not change between the two studies. Nasal resistance decreased significantly after nasal surgery. The composition of the total sleep time spent in the rapid eye movement stage increased from 11.5 +/- 1.3% (mean +/- SEM) to 14 +/- 1.2% after surgery. For the group as the whole, there was no difference between baseline and postsurgical values in the frequency of respiratory disturbances (39.8 +/- 6.1, 36.8 +/- 5.9 n/h), the total apnea time (17.8 +/- 4.2, 15.4 +/- 2.8), the distribution of the apnea time within the different apnea types (obstructive and nonobstructive), and the severity of the nocturnal desaturations. Interestingly, apnea and apnea plus hypopnea indices returned to normal values (< 5 and 10, respectively) in four subjects with normal posterior soft tissues and mandibular plane to the hyoid bone distances.(ABSTRACT TRUNCATED AT 250 WORDS)

    Objective: Severe scoliosis refers to scoliosis with serious and stiff curve. It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon.Methods:Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thoracic plasty.Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80.6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average.Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation.

    Liver hydatidosis is a focal benign parasitic disease that still cause high rate of morbidity particularly in the Mediterranean area. A retrospective study comparing conservative and radical techniques in a General and Urgent Surgery operative unit was carried out in order to find signs of its surgical treatment. A total of 50 patients, 24 men and 26 women, who experienced a surgical treatment from 2000 to 2011, participated, and through the Fisher's Exact Test characteristics of the cysts, post-operative complications and relapse were compared. As a result, 29 patients undertook conservative surgery, while 21 radical surgery. There was a relationship between characteristics of the cysts and the technique chosen, (pcase (p<0.14). In conclusion, in a non hepato-bilio-pancreatic center a radical surgery including liver resection is suggested for left lobe's cysts, while a conservative technique tends to be more effective for right lobe's cysts mainly if complex. Consequently, patients with complicated presentation could explain why conservative treatment causes higher rate of morbidity.

    To investigate incidence, risk factors, and complications of vertebral subluxation (VS) during three-column osteotomy in surgical correction of adult spine deformity. Adult spine deformity patients who underwent three-column osteotomies including VCR, PSO, and other modified types from March 2000 to December 2014 in our center were retrospectively reviewed. The following parameters were measured pre- and postoperatively: Cobb angle of main curve, global kyphosis, sagittal vertical axis, and kyphosis flexibility. Radiographic parameters between groups (VCR vs. PSO and subluxation vs. non-subluxation) were compared. 171 ASD patients were recruited, 18 of which (10.5%) developed sagittal vertebral subluxation at the osteotomy site. 5 of 18 patients (27.8%) developed neurological complications after surgery. For these five patients, two patients got partial recovery, and three got complete recovery at 2-year follow-up. 116 patients underwent PSO, 12 of which (10.3%) developed sagittal vertebral subluxation. In 55 patients receiving VCR, 6 (10.9%) developed sagittal vertebral subluxation. No significant difference was noted between the two groups (P > 0.05). The mean age of VS group was larger than that of non-VS group (46.2 vs. 34.2, P column osteotomies, one-fourth of which would develop neurological deficits. Older age, rigid kyphosis, and the pre-existence of VS were risk factors for developing VS.

    The purpose of this study was to assess the effects of recent surgical rib fixation and establish its indications not only for flail chest but also for multiple rib fractures. Between 2007 and 2015, 187 patients were diagnosed as having multiple rib fractures in our institution. After the propensity score matching was performed, ten patients who had performed surgical rib fixation and ten patients who had treated with non-operative management were included. Categorical variables were analyzed with Fischer's exact test and non-parametric numerical data were compared using the Mann-Whitney U test. Wilcoxon signed-rank test was performed for comparison of pre- and postoperative variables. All statistical data are presented as median (25-75 % interquartile range [IQR]) or number. The surgically treated patients extubated significantly earlier than non-operative management patients (5.5 [1-8] vs 9 [7-12] days: p = 0.019). The duration of continuous intravenous narcotic agents infusion days (4.5 [3-6] vs 12 [9-14] days: p = 0.002) and the duration of intensive care unit stay (6.5 [3-9] vs 12 [8-14] days: p = 0.008) were also significantly shorter in surgically treated patients. Under the same ventilating conditions, the postoperative values of tidal volume and respiratory rate improved significantly compared to those values measured just before the surgery. The incidence of pneumonia as a complication was significantly higher in non-operative management group (p = 0.05). From the viewpoints of early respiratory stabilization and intensive care unit disposition without any complications, surgical rib fixation is a sufficiently acceptable procedure not only for flail chest but also for repair of severe multiple rib fractures.

  1. Bias correction of multi-variate indices: Heat stress in Switzerland

    High resolution regional climate model (RCM) simulations are important tools to provide the meteorological variables required in climate impact assessments. Despite the advances towards higher spatial resolution and better resolved physical processes, RCMs often cannot be directly used in impact studies due to their partly substantial biases. In the climate change context, distributional bias correction (BC) methods are frequently used to deal with systematic model biases. BC methods can correct either some parameters of the distribution (e.g. the mean via distributional shift or scaling) or all quantiles (e.g. via the empirical quantile mapping). The empirical quantile mapping (QM) is widely used in the literature to bias correct individual variables (e.g. temperature, precipitation), in a few cases also for variables such as humidity or wind. In the present work we analyze the suitability of QM to derive a multi-variate index (the wet bulb temperature, WBT) from the new generation of climate change scenarios for Switzerland (CH2018). WBT is a relatively simple proxy for heat stress on the human body. It is a simple, but non-linear multi-variate index that depends on temperature and humidity. Since extreme heat stress conditions occur at sub-daily scale but only daily values are usually available from RCMs, we analyze the sensitivity of the WBT to the use of different daily aggregated values in its calculation, compared to the maximum WBT obtained from observed hourly data. Further, we show that the separate correction of temperature and humidity allows reproduction of the distribution of the daily maximum WBT. Additionally, we explore climate change projections of WBT comparing the results from bias corrected and raw RCM data using a selection of EURO-CORDEX RCM simulations.

  2. The importance of determining surgical indications in cases of lung cancer and interstitial pneumonia with multiple intrapulmonary lymph nodes

    Discussion and conclusions: The greatest problem in treating pulmonary cancer complicated with interstitial pneumonia is acute exacerbation, wherein, in the absence of any surgical indications, alternative treatment is limited. Thus, contra-indicating surgery for a patient due to a diagnosis of metastasis within the lungs, based only on nodule images, should be avoided. If nodules are noted in the area of the pleura, the possibility exists that these could be intrapulmonary lymph nodes, along with metastasis within the lung, and thoracoscopic surgery should be implemented proactively while keeping these in mind.

  3. Mesio-temporal ictal semiology as an indicator for surgical treatment of epilepsies with large multilobar cerebral lesions.

    Mesio-temporal ictal semiology is sometimes observed in patients with large multilobar lesion. In this situation, surgery is often discarded because of the lesion size and/or suspicion of extended or multifocal epileptogenic areas. In this retrospective study we evaluated the surgical outcome of such patients in order to assess whether the electro-clinical presentation of seizures could be a prognostic marker of surgical outcome. Among the temporal lobe epilepsy population explored in our department between 2000 and 2011 (240 patients), we identified 7 patients who presented an extensive lesion on brain Magnetic Resonance Imaging (MRI) (multilobar in four, hemispheric in two, and bilateral in one). All patients underwent (18)Fluorodeoxyglucose Positron Emission Tomography, which showed large, hemispheric or multilobar, areas of glucose hypometabolism. Because of the large lesion size, all patients were explored by stereoelectroencephalography (SEEG) before taking a decision regarding surgical indication. SEEG confirmed the temporal origin of the seizures and discarded the possibility of multiple epileptogenic zones. A temporal lobectomy, tailored on the basis of SEEG data, was proposed to the seven patients. The seven patients are classified Engel class I after the surgery (mean follow-up: 37.4±22.1 months). Our data thus suggest that, even in the absence of hippocampal MRI abnormality, ictal symptoms compatible with a temporal origin of seizures should be considered as a reliable indicator for surgery eligibility regardless of MRI lesion size. On the basis of our findings, the mesio-temporal semiology of seizures appears as one of the most reliable markers of operability in patients with large MRI lesions. These patients should not be excluded a priori from invasive exploration and surgical treatment, even if a large portion of their lesion is likely to be left in place after surgery.

    This study presents the results of surgery in the elderly for primary hyperparathyroidism (PHPT) from a single institution's experience. We retrospectively analyzed 898 cases of surgically treated PHPT, divided into two groups: 135 elderly patients (A) and 763 patients younger than 65 years (B). PHPT was symptomatic in 68.8 per cent patients in group A and in 81.6 per cent in group B. Unilateral temporary recurrent laryngeal nerve palsy was observed in 0.9 per cent in group A and 0.1 per cent in group B (P > 0.05). No cervical hematomas, mortality or major cardiovascular, neurological, respiratory or metabolic postoperative complications were registered. All the patients evaluated at one year had improvement in the quality of life, with increase of bone mineral density (BMD) in 85.6 per cent and 79.8 per cent of patients in groups A and B, with no significant differences between symptomatic and asymptomatic patients. Parathyroidectomy in elderly PHPT patients is safe, with rate of morbidity similar to what observed in younger individuals. Further investigations are recommended to confirm the role of surgery as an effective approach in elderly PHPT patients.

    Full Text Available Background: Identifying infections early, commencing appropriate empiric antibiotic not only helps gain control early, but also reduces mortality and morbidity. Conventional cultures take about 5 days to identify infections. To identify the infections early biomarker like serum procalcitonin (SPC. Aims: We studied the correlation of an elevated level of SPC and positive culture in elective adult patients undergoing cardiac surgery. Methods: This prospective study was conducted from January to December 2013. SPC was checked in patients showing evidence of sepsis. Simultaneously, relevant culture was also undertaken. Correlation, specificity, and sensitivity of elevated SPC were checked. Results: A total of 819 adult patients were included in the study. 43 of them had signs of infection and SPC levels were checked. Based on the level of SPC criteria, 10 patients were diagnosed as "nil", out of them, 4 had culture-positive infections, 17 were suggested to have "mild infection," 3 out those had culture positivity. None among the eleven patients suggested to have "moderate infection," had a positive culture, and one among the five suggested to have a severe infection had a positive culture. The sensitivity was 50% and the specificity 17%. The positive predictive value was 12% and the negative predictive value 60%. Conclusions: We failed to elicit positive correlation between elevated SPC levels and postoperative infection in cardio surgical patients.

    To describe the characteristics of neurogenic heterotopic ossification (NHO) based on clinical tests, electroneuromyography (ENMG) and CT in a database of patients with lesions of the central nervous system who required sciatic nerve neurolysis along with posterior hip NHO resection, and to determine the respective roles of ENMG and CT in the management of posterior hip NHOs in patients who are unable to communicate or express pain. The consistency of the ENMG results with clinical findings, CT results and macroscopic signs of lesions was retrospectively assessed after sciatic nerve neurolysis and ablation of 55 posterior hip NHOs. Sciatic nerve neurolysis was necessary in 55 cases (47.4 %; 55 out of 116). CT showed contact of the NHO with the nerve in all cases: 5 in contact with no deflection, 3 in contact with deflection, 21 moulded into a gutter and 26 entrapped in the NHO. There were clinical signs of sciatic nerve lesion in 21.8 % of cases (12 out of 55). ENMG showed signs of sciatic nerve lesions in only 55.6 % (10 out of 18), only 4 of whom presented with clinical signs of a nerve lesion. No significant relationship was found between clinical symptoms and ENMG findings of sciatic nerve compression (n = 13, p = 0.77). Nerve compression by NHO is likely an underdiagnosed condition, particularly in patients who are unable to communicate. Diagnosis of sciatic compression by NHO should be based on regular clinical examinations and CT. ENMG is not sufficiently sensitive to be used alone for surgical decision-making. (orig.)

    The whole metabolism of a sponge holobiont and the respective contributions of prokaryotic and eukaryotic symbionts and their associations with the sponge host remain largely unclear. Meanwhile, compared with shallow water sponges, deep-sea sponges are rarely understood. Here we report the metagenomic exploration of deep-sea sponge Neamphius huxleyi [corrected] . at the whole community level. Metagenomic data showed phylogenetically diverse prokaryotes and eukaryotes in Neamphius huxleyi [corrected]. MEGAN and gene enrichment analyses indicated different metabolic potentials of prokaryotic symbionts from eukaryotic symbionts, especially in nitrogen and carbon metabolisms, and their molecular interactions with the sponge host. These results supported the hypothesis that prokaryotic and eukaryotic symbionts have different ecological roles and relationships with sponge host. Moreover, vigorous denitrification, and CO2 fixation by chemoautotrophic prokaryotes were suggested for this deep-sea sponge. The study provided novel insights into the respective potentials of prokaryotic and eukaryotic symbionts and their associations with deep-sea sponge Neamphius huxleyi [corrected].

    1170 patients after surgical correction of aortic coarctation during the period from 1988 to 2002 were studied. The median period of medical supervision after coarctation repair was 13,8 years, maximum age - 24 years. For diagnostics of the Microalbuminuria (MAU) it were used the special test-strings Microalbu PHAN (PLIVA-Lachema Diagnostica). MAU were discovered in 62.6% of and 34.9% of normotesive patients. Credible decrease of MAU of hypertensive patients with corrected coarctation of the aorta were defined after 3 months-long treatment by Losartan.

    Full Text Available Fast-track extubation is an established safe practice in pediatric congenital heart disease (CHD surgical patients. On table extubation (OTE in acyanotic CHD surgical patients is well established with validated safety profile. This practice is not yet reported in tetralogy of Fallot (TOF cardiac surgical repair patients in developing countries. Evidence suggests that TOF total correction patients should be extubated early, as positive pressure ventilation has a negative impact on right ventricular function and the overall increase in post-TOF repair complications such as low cardiac output state and arrhythmias. The objective of the case series was to determine the safety and feasibility of OTE in elective TOF total correction cardiac surgical patients with an integrated team approach. To the best of our knowledge, this is the first reported case series. A total of 8 elective male and female TOF patients were included. Standard anesthetic, surgical and perfusion techniques were used in these procedures. All patients were extubated in the operating room safely without any complications with the exception of one patient who continued to bleed for 3 h of postextubation at 2-3 ml/kg/h which was managed with transfusion of fresh frozen plasma at 15 mL/kg, packed red blood cells 10 mL/kg and bolus of transamine at 20 mg/kg. Apart from better surgical and bypass techniques, the most important factor leading to successful OTE was an excellent analgesia. On the basis of the case series, it is suggested to extubate selected TOF cardiac surgery repair patients on table safely with integrated multidisciplinary approach.

All patients were extubated in the operating room safely without any complications with the exception of one patient who continued to bleed for 3 h of postextubation at 2-3 ml/kg/h which was managed with transfusion of fresh frozen plasma at 15 mL/kg, packed red blood cells 10 mL/kg and bolus of transamine at 20 mg/kg. Apart from better surgical and bypass techniques, the most important factor leading to successful OTE was an excellent analgesia. On the basis of the case series, it is suggested to extubate selected TOF cardiac surgery repair patients on table safely with integrated multidisciplinary approach.

    Orbitopalpebral anomalies in mandibulofacial dysostosis (Treacher-Collins syndrome) can be difficult to correct surgically and most authors recommend correction of the malar bone after the age of 8 years. We propose a new, early surgical approach for periorbital defects that involves initial implantation of autologous fat and subperiosteal malar lift with a pedicled upper eyelid flap. We prospectively studied 5 children, 3 of whom had previously had orbital reconstruction. Initial fat graft into the periorbital area was followed by a subperiosteal malar lift with lateral canthopexy, and a pedicled upper eyelid flap if needed. Two surgeons independently assessed the patients' characteristics including scleral show before and after operation, antimongoloid palpebral fissures, canthal dystopia, number 6 cleft (Tessier classification), skin quality, and surgical and ophthalmic complications. Before operation 3 patients had had ophthalmic problems. Postoperative evaluation showed improvements in scleral show, canthal dystopia, and skin quality, and correction of antimongoloid palpebral fissures and subcutaneous number 6 clefts. There were no postoperative complications. The proposed protocol gave satisfactory aesthetic and functional results in children with Treacher-Collins syndrome. We recommend that it is considered for periorbital reconstruction in all patients with a mandibulofacial deformity.

    To define and demonstrate effective cataract surgical coverage (eCSC), a candidate UHC indicator that combines a coverage measure (cataract surgical coverage, CSC) with quality (post-operative visual outcome). All Rapid Assessment of Avoidable Blindness (RAAB) surveys with datasets on the online RAAB Repository on April 1 2016 were downloaded. The most recent study from each country was included. By country, cataract surgical outcome (CSOGood, 6/18 or better; CSOPoor, worse than 6/60), CSC (operated cataract as a proportion of operable plus operated cataract) and eCSC (operated cataract and a good outcome as a proportion of operable plus operated cataract) were calculated. The association between CSC and CSO was assessed by linear regression. Gender inequality in CSC and eCSC was calculated. Datasets from 20 countries were included (2005-2013; 67,337 participants; 5,474 cataract surgeries). Median CSC was 53.7% (inter-quartile range[IQR] 46.1-66.6%), CSOGood was 58.9% (IQR 53.7-67.6%) and CSOPoor was 17.7% (IQR 11.3-21.1%). Coverage and quality of cataract surgery were moderately associated-every 1% CSC increase was associated with a 0.46% CSOGood increase and 0.28% CSOPoor decrease. Median eCSC was 36.7% (IQR 30.2-50.6%), approximately one-third lower than the median CSC. Women tended to fare worse than men, and gender inequality was slightly higher for eCSC (4.6% IQR 0.5-7.1%) than for CSC (median 2.3% IQR -1.5-11.6%). eCSC allows monitoring of quality in conjunction with coverage of cataract surgery. In the surveys analysed, on average 36.7% of people who could benefit from cataract surgery had undergone surgery and obtained a good visual outcome.

    Full Text Available Abstract Background Intraductal papillary mucinous neoplasms (IPMNs are increasingly recognized entities, whose management remains sometimes controversial, due to the high rate of benign lesions and on the other side to the good survival after resection of malignant ones. Methods Retrospective analysis of a prospectively collected Western series of IPMN. Results Forty cases of IPMN were analysed (1992-2007. Most patients were symptomatic (72.5%; cholangio-MRI had the best diagnostic accuracy both for the tumour nature (83.3% and for the presence of malignancy (57.1%. ERCP was done in 8 cases (20%, and the results were poor. Thirteen patients were treated by pancreatic resection and 27 were maintained in follow-up. Total pancreatectomy was performed in 46% of the cases; in situ and invasive carcinoma were recognized in 15.4% and 38.4% of the cases, respectively. The mean follow-up was 42 months (range 12-72. One only patients with nodal metastases died 16 months after the operation for disease progression, while 91.6% of the operated patients are disease free. Out of the 27 not resected patients, 2 out of 4 presenting a lesion at high risk for malignancy died, while the remaining are in good conditions and disease free, with a mean follow-up of 31 months. Conclusion Therapeutic indication for IPMNs is mainly based upon radiological evaluation of the risk of malignancy. While the main duct tumours should be resected, preserving whenever possible a portion of the gland, the secondary ducts tumours may be maintained under observation, in absence of radiological elements of suspicion such as size larger than 3 cm, or a wall greater than 3 mm or nodules or papillae in the context of the cyst.

    Use of surgery for the treatment of infective endocarditis (IE) as related to surgical indications and operative risk for mortality has not been well defined. The International Collaboration on Endocarditis-PLUS (ICE-PLUS) is a prospective cohort of consecutively enrolled patients with definite IE from 29 centers in 16 countries. We included patients from ICE-PLUS with definite left-sided, non-cardiac device-related IE who were enrolled between September 1, 2008, and December 31, 2012. A total of 1296 patients with left-sided IE were included. Surgical treatment was performed in 57% of the overall cohort and in 76% of patients with a surgical indication. Reasons for nonsurgical treatment included poor prognosis (33.7%), hemodynamic instability (19.8%), death before surgery (23.3%), stroke (22.7%), and sepsis (21%). Among patients with a surgical indication, surgical treatment was independently associated with the presence of severe aortic regurgitation, abscess, embolization before surgical treatment, and transfer from an outside hospital. Variables associated with nonsurgical treatment were a history of moderate/severe liver disease, stroke before surgical decision, and Staphyloccus aureus etiology. The integration of surgical indication, Society of Thoracic Surgeons IE score, and use of surgery was associated with 6-month survival in IE. Surgical decision making in IE is largely consistent with established guidelines, although nearly one quarter of patients with surgical indications do not undergo surgery. Operative risk assessment by Society of Thoracic Surgeons IE score provides prognostic information for survival beyond the operative period. S aureus IE was significantly associated with nonsurgical management. © 2014 American Heart Association, Inc.

    A 10 week old female intact Staffordshire terrier was presented with a total of five congenital cardio-thoracic vascular anomalies consisting of a patent ductus arteriosus (PDA) with an aneurysmic dilation, pulmonic stenosis, persistent right aortic arch, aberrant left subclavian artery and persistent left cranial vena cava. These abnormalities were identified with a combination of echocardiogram and computed tomography angiography (CTA). The abnormalities were associated with esophageal entrapment, regurgitation, and volume overload of the left heart with left atrial and ventricular enlargement. A 2 cm diameter aneurysmic dilation at the junction of the PDA, right aortic arch and aberrant left subclavian artery presented an unusual surgical challenge and precluded simple circumferential ligation and transection of the structure. A full scale three dimensional model of the heart and vasculature was constructed from the CTA and plasma sterilized. The model was used preoperatively to facilitate surgical planning and enhance intraoperative communication and coordination between the surgical and anesthesia teams. Intraoperatively the model facilitated spatial orientation, atraumatic vascular dissection, instrument sizing and positioning. A thoracoabdominal stapler was used to close the PDA aneurysm prior to transection. At the four-month postoperative follow-up the patient was doing well. This is the first reported application of new imaging and modeling technology to enhance surgical planning when approaching correction of complex cardiovascular anomalies in a dog.

    "Popeye biceps" deformity represents the appearance of a distally retracted biceps muscle resulting from either a traumatic long biceps tendon (LBT) rupture or an iatrogenic LBT tenotomy. Cosmetic and functional problems associated with the deformity may necessitate surgical correction, and surgical exposure using multiple incisions is recommended. The technique presented here describes a novel mini-open approach using a single 1-in incision that provides access to 3 peripectoral anatomical zones. Preoperative sonographic localization of the ruptured and retracted LBT is used to guide incision placement, and facilitates intraoperative tendon retrieval via a limited incision and minimal dissection. Inferolateral retraction of the mini-incision window permits infrapectoral and subpectoral LBT mobilization and dissection. Deltopectoral access via superomedial retraction of the same skin window is used to expose the suprapectoral zone and is employed for LBT retrieval and proximal tenodesis. Technical tips for safe dissection via a mini-incision, and methods for biological LBT augmentation are discussed.

    We studied the occurrence and extent of malnutrition and maldigestion in 13 patients who underwent pancreatoduodenectomy (PD) and injection of Neoprene (polychloroprene) (NI) into the duct of Wirsung, which results in sclerosis of hte acinar pancreatic tissue, but spares the endocrine function. At discharge, patients under took an enzyme supplementation regimen with pancreatin (18, 00 United States Pharmacopoeia units of lipase per meal). Patients were rehospitalized 24.9 months after PD plus NI to undergo nutritional and metabolic evaluation (hospital control). Nutritional status was evaluated by measuring the serum albumin level, total iron binding capacity and total lymphocyte count. Digestive function was assessed by the D-xylose tolerance test and determination of fecal fat excretion. Patients were then discharged with pancrelipase, enteric-coated microspheres (ECM) supplementation (16,050 United States Pharmacopoeia units of lipase per meal). Malnutrition, defined as the occurrence of at least two abnormal nutritional parameters, was observed in six patients at hospital control. After six months on pancrelipase ECM, the nutritional status was re-evaluated in nine patients (three previously malnourished) who were all well nourished. The mean body weight was 84.7 per cent of usual body weight at discharge after PD plus NI and raised to 88.0 per cent at the hospital control (p less than 0.01) and to 93.7 per cent )p less than 0.05) after six months on pancrelipase ECM. At hospital control, results from the D-xylose test were normal in all patients, and steatorrhea dropped from 33.6 grams per day without enzyme supplementation to 15.3 grams per day with pancrelipase ECM (16,050 United States Pharmacopoeia units of lipase per meal). Steatorrhea was incompletely but satisfactorily corrected by pancrelipase ECM. On supplementation therapy with pancrelipase ECM, patients recover a good deal of the body weight and normalize the biochemical indices of malnutrition.

    Experienced homing pigeons with extirpated cochleae and lagenae were released from six sites in upstate New York and western Pennsylvania on 17 days between 1973 and 1975 by William T. Keeton and his co-workers at Cornell University. The previously unpublished data indicate that departure directions of the operated birds were significantly different from those of sham-operated control birds (314 total), indicating that aural cues play an important part in the pigeon's navigational system. Moreover, propagation modeling of infrasonic waves using meteorological data for the release days supports the possibility that control birds used infrasonic signals to determine their homeward direction. Local acoustic 'shadow' zones, therefore, could have caused initial disorientation of control birds at release sites where they were normally well oriented. Experimental birds plausibly employed an alternate 'route-reversal' strategy to return home perhaps using their ocular-based magnetic compass. We suggest, based on Keeton's results from another site of long-term disorientation, that experienced pigeons depend predominantly on infrasonic cues for initial orientation, and that surgical removal of their aural sense compelled them to switch to a secondary navigational strategy.

    This retrospective study analyzed the pool of patients referred for treatment with dental implants over a 3-year period in a referral specialty clinic. All patients receiving dental implants between 2002 and 2004 in the Department of Oral Surgery and Stomatology, University of Bern, were included in this retrospective study. Patients were analyzed according to age, gender, indications for implant therapy, location of implants, and type and length of implants placed. A cumulative logistic regression analysis was performed to identify and analyze potential risk factors for complications or failures. A total of 1,206 patients received 1,817 dental implants. The group comprised 573 men and 633 women with a mean age of 55.2 years. Almost 60% of patients were age 50 or older. The most frequent indication for implant therapy was single-tooth replacement in the maxilla (522 implants or 28.7%). A total of 726 implants (40%) were inserted in the esthetically demanding region of the anterior maxilla. For 939 implants (51.7%), additional bone-augmentation procedures were required. Of these, ridge augmentation with guided bone regeneration was performed more frequently than sinus grafting. Thirteen complications leading to early failures were recorded, resulting in an early failure rate of 0.7%. The regression analysis failed to identify statistically significant failure etiologies for the variables assessed. From this study it can be concluded that patients referred to a specialty clinic for implant placement were more likely to be partially edentulous and over 50 years old. Single-tooth replacement was the most frequent indication (> 50%). Similarly, additional bone augmentation was indicated in more than 50% of cases. Adhering to strict patient selection criteria and a standardized surgical protocol, an early failure rate of 0.7% was experienced in this study population.

    To determine whether preoperative administration of erythromycin or flunixin meglumine altered postoperative abomasal emptying rate, rumen contraction rate, or milk production in dairy cattle undergoing surgical correction of left displacement of the abomasum (LDA). Nonrandomized, controlled clinical trial. 45 lactating Holstein-Friesian cows with LDA. Cows were alternately assigned to an erythromycin (10 mg/kg [4.5 mg/lb], IM), flunixin (2.2 mg/kg [1.0 mg/lb], IV), or control group (n = 15/group). Treatments were administered once 1 hour before surgical correction of LDA. D-Xylose solution (50%; 0.5 g/kg [0.23 g/lb]) was injected into the abomasal lumen during surgery, and venous blood samples were periodically obtained to determine time to maximum serum D-xylose concentration. Abomasal emptying rate was significantly faster in cows treated with erythromycin (mean +/- SD time to maximum serum D-xylose concentration, 149 +/- 48 minutes) than in control cows (277 +/- 95 minutes) but was not significantly different between cows treated with flunixin (230 +/- 49 minutes) and control cows. Cows treated with erythromycin had significantly greater milk production, relative to production before surgery, on postoperative days 1 and 2 than did control cows. Cows in the erythromycin and flunixin groups had a significantly higher rumen contraction rate on the first postoperative day than did control cows. Results suggested that preoperative administration of a single dose of erythromycin increased abomasal emptying rate, rumen contraction rate, and milk production in the immediate postoperative period in cows undergoing surgical correction of LDA.

    Draf in 1991. The procedure--which is also known as the modified endoscopic Lothrop procedure--aims to create the largest possible anteroposterior and lateral to lateral opening between both frontal sinuses and the nasal cavities. This requires the resection of the medial floor of both frontal sinuses, the intersinus septum and the superior nasal septum. The authors present a retrospective study including a cohort of 120 patients who underwent surgery in six Belgian university ENT departments. Mean follow-up was 24.6 months (range: 5-36 months). This paper describes the surgical procedure and reviews the indications, comorbidities, outcomes and complications of the type III frontal sinusotomy. Some correlations are also established with the data published in the worldwide literature. The authors conclude that the Draf III is a demanding procedure requiring considerable expertise in endoscopic sinus surgery. The procedure is effective with a success rate of 87.5%. Indeed, 12.5% of patients only experienced closure of the neoostium while 20% of all the patients had unchanged or worse symptomatology. The percentage of post-operative complications is 7.5%. All complications were managed successfully.

    Initially considered experimental, liver transplantation (LT) has become the treatment of choice for the patients with end-stage liver diseases. Between April 2000 and October 2009, 200 LTs (10 reLTs) were performed in 190 patients, this study being retrospective. There were transplanted 110 men and 80 women, 159 adults and 31 children with the age between 1 and 64 years old (mean age--39.9). The main indication in the adult group was represented by viral cirrhosis, while the pediatric series the etiology was mainly glycogenosis and biliary atresia. There were performed 143 whole graft LTs, 46 living donor LTs, 6 split LTs, 4 reduced LTs and one domino LT RESULTS: The postoperative survival was 90% (170 patients). The patient and graft one-year and five-year survivals were 76.9%, 73.6% and 71%, 68.2%, respectively. The early complications occurred in 127 patients (67%). The late complications were recorded in 71 patients (37.3%). The intraoperative and early postoperative mortality rate was 9.5% (18 patients). The Romanian liver transplantation program from Fundeni includes all types of current surgical techniques and the results are comparable with those from other international centers.

    Scoliosis, a three-dimensional deformity, has secondary effects on the gastrointestinal system. Reflux gastroesophagitis with hiatus hernia in patients with scoliosis is difficult to manage. We present a patient in whom primary correction of a spinal deformity was associated with resolution of symptoms of reflux. A 15-year-old girl with severe thoracolumbar kyphoscoliosis visited our scoliosis research institute complaining of back pain, positional imbalance, intermittent respiratory tract infections, and gastrointestinal discomfort such as pain, dysphagia, and heartburn for several years. On preoperative CT, her abdominal organs were in a deviant position, and esophagogastroduodenoscopy revealed severe reflux gastroesophagitis, Los Angeles classification (LA) Grade D, and a sliding hiatus hernia. After kyphoscoliosis correction, the patient's truncal balance and pain improved. Postoperatively, the patient reported abdominal pain and dysphagia that gradually subsided after 3 weeks. At 1 year, the patient had no abdominal complaints secondary to reflux gastroesophagitis, and episodes of recurrent respiratory tract infections were substantially reduced. Postoperative evaluation showed the reflux gastroesophagitis had improved to LA Grade A. Postoperative CT showed the abdominal cavity had expanded and the abdominal organs were more centered. The association between scoliosis and reflux gastroesophagitis is well documented. However, the secondary effects of scoliosis correction on gastrointestinal symptoms caused by reflux gastroesophagitis have not been investigated in detail. This patient illustrates the relationship between spinal deformity and gastrointestinal symptoms. Postural balance correction resulted in the alleviation of reflux gastroesophagitis symptoms secondary to hiatus hernia.

    Three-dimensional planning based on computed tomography images of the malunited and the mirrored contralateral forearm allows preoperative simulations of corrective osteotomies, the fabrication of patient-specific osteotomy guides, and custom-made 3-dimensional printed titanium plates. This study aims to assess the precision and clinical outcome of this technique. This was a prospective pilot study with 5 consecutive patients. The mean age at initial injury was 11 years (range, 4-16 years), and the mean interval from the time of injury to the time of corrective surgery was 32 months (range, 7-107 months). Patient-specific osteotomy guides and custom-made plates were used for multiplanar corrective osteotomies of both forearm bones at the distal level in 1 patient and at the middle-third level in 4 patients. Patients were assessed before and after surgery after a mean follow-up of 42 months (range, 29-51 months). The mean planned angular corrections of the ulna and radius before surgery were 9.9° and 10.0°, respectively. The mean postoperative corrections obtained were 10.1° and 10.8° with corresponding mean errors in correction of 1.8° (range, 0.3°-5.2°) for the ulna and 1.4° (range, 0.2°-3.3°) for the radius. Forearm supination improved significantly from 47° (range, 25°-75°) before surgery to 89° (range, 85°-90°) at final review. Forearm pronation improved from 68° (range, 45°-84°) to 87° (range, 82°-90°). In addition, there was a statistically significant improvement in pain and grip strength. This study demonstrates that 3-dimensional planned patient-specific guides and implants allow the surgeon to perform precise corrective osteotomies of complex multiplanar forearm deformities with satisfactory preliminary results.

    Full Text Available Purpose: Genital reconstruction in female patients with virilizing congenital adrenal hyperplasia (CAH is very challenging. Our aim was to evaluate the techniques employed to treat complications after failure of primary urogenital sinus (UGS surgery, as well as the result of these reoperations.Patients and Methods: Twenty girls with virilizing CAH who were previously submitted to genitoplasty in our service and elsewhere had recurrent UGS stenosis and vaginal introitus stenosis that required surgical treatment. The main symptoms were recurrent urinary tract infection (UTI in nine, dyspareunia in six and hematocolpos in three (two associated with sepsis. The anatomical findings were the persistence of UGS with stenosis in 17 patients and vaginal introitus stenosis in three. The mean age at procedure was 15.2 yrs., averaging 13.1 yrs. after the first surgery. The surgical techniques employed were: isolated perineal flap in 17 patients and perineal flap with partial mobilization of UGS in three. The mean follow-up after the procedure was 4.8 years (varying from 1 to 17yrs.Results: Vaginal dilations were performed after surgery in 15 patients. Good functional and anatomical results were obtained in 15 patients, with vaginal introitus amenable to dilators of 3.0 cm in diameter. Five patients with high vaginal insertion had recurrent vaginal stenosis and required a surgical revision. No patients presented menstrual obstruction or UTI after surgery. Eight of the 15 adult patients are sexually active. Conclusion: The reoperation to treat failed primary UGS treatment using Y-V flap and partial mobilization techniques associated to vaginal dilations, promoted good anatomical and functional results with low morbidity in 75% of the patients.□

    Ulnar deviation deformity of the wrist in patients with birth brachial plexus palsy is an important cosmetic concern among the patients and their relatives; especially in the patients who have recovered the basic limb functions. Though there is ample literature available regarding the management of the shoulder deformity there is paucity of literature regarding management of wrist ulnar deviation deformity. We report our experience with correction of this deformity in five cases with isolated ulnar deviation deformity without forearm rotational deformity or weakness of the wrist muscles. All the patients underwent extensor carpi ulnaris (ECU) to extensor carpi radialis longus (ECRL) tendon transfer. At a minimum of 18 months follow-up all the patients and their families were satisfied with the cosmetic appearance of the limb. Correction of the deformity improves the appearance of the limb, improves self-confidence of the child, and allows them to integrate well into the society. Interestingly, the patients expressed improvement in their grip strength and overall hand function after this surgery. The notable functions which improved were easy reach of the hand-to-mouth for feeding and easy handling of the things requiring bimanual activities. Although the main aim of this operation was to correct the appearance of the hand it was found to be also functionally useful by the patients and hence we are encouraged to report it for wider use. The results were maintained during the follow-up period of as long as 47 months.

    Full Text Available This retrospective study was designed to investigate the correlation between a novel immunosubtyping method for hepatocellular carcinoma (HCC and biological behavior of tumor cells. A series of 346 patients, who received hepatectomy at two surgical centers from January 2007 to October 2010, were enrolled in this study. The expressions of cytokeratin 19 (CK19, glypican 3 (GPC3, and CD34 were detected by immunohistochemical staining. The clinical stage was assessed using the sixth edition tumor-node-metastasis (TNM system (UICC/AJCC, 2010.Vascular invasion comprised both microscopic and macroscopic invasion. The tumor size, lymph node involvement, and metastasis were determined by pathological as well as imaging studies. Recurrence was defined as the appearance of new lesions with radiological features typical of HCC, seen by at least two imaging methods. Survival curves for the patients were plotted using the Kaplan-Meier method, and differences between the curves were assessed using the log-rank test. Significant differences in morphology, histological grading, and TNM staging were observed between groups. Based on the immunohistochemical staining, the enrolled cases were divided into CK19+/GPC3+, CK19-/GPC3+ and CK19-/GPC3- three subtypes. CK19+/GPC3+ HCC has the highest risk of multifocality, microvascular invasion, regional lymph node involvement, and distant metastasis, followed by CK19-/GPC3+ HCC, then CK19-/GPC3-HCC. CK19+/GPC3+ HCC has the shortest recurrence time compared to other immunophenotype HCCs. CK19 and GPC3 expression profiling is an independent prognostic indicator in patients with HCC, and a larger sample size is needed to further investigate the effect of this immunosubtyping model in stratifying the outcome of HCC patients.

    Purpose Diabetes mellitus (DM) is the most common cause of end-stage renal disease and is an important risk factor for morbidity and mortality after dialysis. However, glycemic control among such patients is difficult to assess. The present study examined glycemic control parameters and observed glucose variation after refilling different kinds of fresh dialysate in peritoneal dialysis (PD) patients. Methods A total of 25 DM PD patients were recruited, and continuous glucose monitoring system (CGMS) was applied to measure interstitial fluid (ISF) glucose levels at 5-min intervals for 3 days. Patients filled out diet and PD fluid exchange diaries. The records measured with CGMS were analyzed and correlated with other glycemic control parameters such as fructosamine, albumin-corrected fructosamine (AlbF), glycosylated hemoglobin (HbA1c), and glycated albumin levels. Results There were significant correlations between mean ISF glucose and fructosamine (r = 0.45, Picodextrin dialysate which kept ISF glucose levels unchanged. Conclusion HbA1c and AlbF significantly correlated with the mean ISF glucose levels, indicating that they are reliable indices of glycemic control in DM PD patients. Icodextrin dialysate seems to have a favorable glycemic control effect when compared to the other glucose-containing dialysates. PMID:23469230

    We aimed to develop an effective system for surgical site infection (SSI) surveillance and examine the current domestic state of SSIs for common abdominal surgeries in Korea. The Korean Surgical Site Infection Surveillance (KOSSIS) program was developed as an SSI surveillance system. A prospective multicenter study in nine university-affiliated or general hospitals was conducted for patients who underwent gastrectomy, cholecystectomy, appendectomy, colectomy, or proctectomy between August 16 and September 30 in 2012. Patients were monitored for up to 30 days by combining direct observation and a postdischarge surgeon survey. Data on SSIs were prospectively collected with KOSSIS secretarial support according to a common protocol. Operation-specific SSI rates were stratified according to risk factors and compared with data from the Korean Nosocomial Infections Surveillance System (KONIS) and National Healthcare Safety Network. A focus group interview was conducted with participating hospitals for feedback. A total of 1,088 operations were monitored: 207 gastrectomies, 318 cholecystectomies, 270 appendectomies, 197 colectomies, and 96 proctectomies. Operation-specific SSI rates determined by the KOSSIS program were substantially higher than those found in KONIS (7.73% [95% confidence interval, 4.5%-12.3%] vs. 3.4% for gastrectomies, 10.15% [95% confidence interval, 6.1%-15.2%] vs. 4.0% for colectomy, and 13.5% [95% confidence interval, 7.4%-22.0%] vs. 4.2% for proctectomy). Despite a short surveillance period and heterogenous group of hospitals, our results suggest that KOSSIS could be a useful program to enhance SSI surveillance in Korea.

    A case report. To report the successful consecutive spinal osteotomies of multiple segments performed on a patient with extremely severe kyphotic deformity. There have been no reports on the experience and surgical strategy of spinal osteotomy on multiple segments for severe global spine deformity. A 48-year-old man, a patient with ankylosing spondylitis with "chin-on-pubis" deformity, underwent consecutive spinal osteotomies to correct the severe, fixed global kyphosis. The axial skeletons from the skull, all vertebrae, and both sacroiliac joints and hip joint were fused into a single bone. After both hip resectional arthroplasties for the first step, staged, sequential spinal osteotomies, including pedicle subtraction osteotomy (PSO) on C6, posterior vertebral column resection on T11-T12, and PSO on L3, were performed. Finally, both total hip arthoroplasties were performed. The chin-brow vertical angle improved from 140° to 15°. Correction angles of 45°, 70°, and 30° in the cervical, thoracic, and lumbar spines, respectively, were achieved without complication. At the last follow-up, excellent improvement in activities of daily living and horizontal gaze were achieved. This is the first report on C6 PSO and spinal osteotomies in whole spine segments. For patients with a severe global kyphotic deformity, it is important to place the patient in a stable prone position so that corrective surgery can be performed on the thoracolumbar spine. To accomplish this, initially correcting the deformities in the hip joints and the cervical spine can yield excellent clinical results.

    We present the case of a 14-year-old male with melorhesotosis and severe iliotibial band tightness which was associated with femoral shortening, severe external rotational deformity of the femur, genu valgum and patellar dislocation in the right lower extremity. Skeletal survey revealed irregular radiodense streaks involving the pelvis, femoral head, femoral shaft, distal femoral epiphysis, talus and middle phalangeal bones of the foot. Magnetic resonance (MR) imaging showed thickening of the iliotibial band in addition to low MR signal changes in the bone. Intraoperatively fibrosis in the subcutaneous layer and a thickened iliotibial band were found. MR images were very useful in understanding the soft tissue pathoanatomy in melorheostosis and planning surgical correction. (orig.)

    Treatment options for Class II malocclusion include orthognathic surgery. Treatment choices are particularly difficult for young patients because of the uncertainty regarding future growth. Surgical treatment has generally been considered necessary for older patients with more severe Class II problems. The treatment records of more than 500 patients with Class II malocclusion were reviewed. Patients were grouped according to their initial treatment plan (surgery or orthodontics) and treatment outcome (overjet [OJ] reduced to function analyses using data from the patient’s pretreatment cephalogram were used to determine whether age, in combination with malocclusion severity, could predict the choice of treatment, and whether a simple set of pretreatment variables could predict the success or failure of OJ reduction. The derived equations were tested in a similar group of growing Class II children. Although the data showed clinicians use patient’s age in determining treatment choice, age did not seem to be associated with treatment outcome. The majority of the variability that determined the success or failure of OJ reduction was not explained by patient’s age or malocclusion severity. These findings suggest other factors, including psychosocial variables, need to be explored if we are to gain a better understanding of why treatments succeed or fail. PMID:10860060

    Full Text Available Adolescent idiopathic scoliosis is a spinal deformity that affects patients’ self image and confidence. Surgery is offered when the curvature is greater than 50 degrees based on the likelihood of curvature progression. Outcome measures for scoliosis correction can be described in terms of radiological improvement or improvement of health related quality of life scores. The Scoliosis Research Society 22 (SRS-22 and Scoliosis Research Society 24 (SRS-24 questionnaires are widely accepted and used to characterize clinical results. Therefore, this prospective study of 38 patients aims to investigate how the SRS-24 and SRS-22 questionnaires compare to each other in terms of scoring when the same group of patients is evaluated. The SRS-22 questionnaire tends to give an inflated value in the overall score, pain and self image domain compared to the SRS-24 questionnaire.

    Full Text Available Abstract Background Rupture of aneurysms of the sinus of Valsalva results in abrupt onset of congestive heart failure. On-pump beating-heart surgery may reduce cardiac impairment by maintaining coronary blood flow and avoiding cardioplegia. Herein, we report the operative correction of thirty-one patients of ruptured aneurysms of the sinus of Valsalva, using the on-pump beating-heart technique. Methods Thirty-one patients with ruptured aneurysms of the sinus of Valsalva underwent operative corrections using the on-pump beating-heart technique. In patients with fistula diameter less than 1 cm and no aortic regurgitation, the aorta was unclamped throughout cardiopulmonary bypass(CPB while receiving antegrade heart perfusion. In remainder of patients, retrograde perfusion was used. Results After intracardiac manipulation was complete and the nasopharyngeal temperature was raised to 36-37°C, the patients were smoothly weaned off CPB. There were no early or late postoperative deaths. All patients were in New York Heart Association functional class I at follow-up (range, 0.5-1 year. Mild-to-moderate aortic valve regurgitation was observed in one patient. No recurrence of the left-to-right shunt from ruptured aneurysms of the sinus of Valsalva was observed. Conclusions Beating heart on pump allows adequate examination of the aortic lesion under near-physiologic conditions, allows decrease in ischemia-reperfusion injury and potentially decreases the risk of serious or fatal rhythm disturbances. On-pump beating-heart technique for repair of ruptured aneurysm of sinus of Valsalva is feasible and promising. Antegrade heart perfusion is suitable for patients with a fistula diameter

The ISF glucose levels in glucose-containing dialysate increased from approximately 7-8 mg/dL within 1 hour of exchange in contrast to icodextrin dialysate which kept ISF glucose levels unchanged. HbA1c and AlbF significantly correlated with the mean ISF glucose levels, indicating that they are reliable indices of glycemic control in DM PD patients. Icodextrin dialysate seems to have a favorable glycemic control effect when compared to the other glucose-containing dialysates.

    Full Text Available Aim: To assess clinical and functional efficacy of implanted biological prosthesis “ASPIRE” (manufactured by Vascutek for correction of mitral valve disease.Materials and methods: From October 2008 to December 2013, biological prostheses “ASPIRE” (Vascutek were implanted to 34 patients with mitral valve disease (mean age 63.59 ± 4.96 years, 79.4% female. From these, 24 patients had mitral stenosis and 10 patients had mitral insufficiency. 73.5% of all patients had heart failure Strazhesko-Vasilenko IIA grade and 85.3% of patients had chronic heart failure NYHA III. Isolated mitral valve replacement was performed only in 8 (23.5% of patients. In 22 (64.7% of cases mitral valve replacement was combined with tricuspid valvuloplasty in various modifications. Duration of cardiopulmonary bypass and of aortic clamping was 88.09 ± 25.95 and 65.68 ± 25.51 minutes, respectively. Before and after surgery all patients underwent echocardiographic assessment and clinical assessment of their general status.Results: In-hospital mortality was 5.88% (n = 2 and was related to multiorgan failure in the early postoperative period. All 32 (94.12% surviving patients improved with decrease or complete disappearance of heart failure. Postoperative complications were typical for cardiac surgery. There were no episodes of embolism, structural dysfunction, thrombosis of the prosthesis and endocarditis of the prosthesis in the early postoperative period. Pressure gradients across prosthetic valves were not high and corresponded to good clinical and hemodynamic results in the early postoperative period.Conclusion: Taking into account good immediate results of mitral valve replacement, as well as no need in lifelong anticoagulation in patients with multiple concomitant disorders, implantation of the biological prosthesis “ASPIRE” (Vascutek could become a procedure of choice for correction of valve abnormalities in patients above 65 years.

    Full Text Available Objectives: To analyze the short and long term results of tapes of different materials used to treat stress urinary incontinence (SUI. A secondary objective was to evaluate the ability to adjust the tape after implantation. Materials and methods: Retrospective chart review of 355 patients with SUI operated between March 2003 and October 2011. Eight different types of transobturator tapes were used: Gynecare TVT-O®, Monarc®, SAFYRE®, Contasure KIM®, I-Stop®, DynaMesh®, Aris® Bandellete and Swing-band®. Results and complications were recorded. Results: The mean age at operation was 61 years. Correction of SUI was achieved in 87.88% of cases. The best results were obtained with Contasure KIM® (98.26 % continence. The tape was well tolerated and was elastic enough to be able to be adjusted 48-72 hours after implantation without deformation. Slings with macropores and over lock stiches on the superior and inferior borders presented the lower rates of postoperative urinary retention, pain, perior postoperative bleeding and urinary tract infections. Conclusions: Transobturator tension free tapes require a short operation time and have a low complication rate. The possibility of adjustment in the early postoperative period increases the success rate and reduces complications. Knotless meshes with macropores and over lock stiches appear to be better balanced, are quite resistant to stretching and deformation when readjusted after implantation and present a low infection rate.

    Presented are the cases of 19 boys with ventral penile curvature without hypospadias. The cases were categorised into three groups according to the severity of the anomaly. In group I were 7 boys with ventral penile curvature affecting the shortening of the frenulum with skin tethering. The anomaly was corrected by fraenulotomy and, in 4 boys, by ventral "V" and "Y" penile skinplasty with excellent cosmetic results. In group II were 10 boys with an evident chordee. In 4 boys, the chordee was of type III according to Devin-Horton. A chordectomy was done with a "V" and "Y" skinplasty with very good result. The remaining 6 cases were chordee type II according to D-H. The same treatment was undertaken here, but with an additional Nesbit's dorsal tunica albuginea plication in 4 boys and a 50% success (3 of 6). In group III were 5 boys, 3 previously failed chordectomy from group II and 2 with "skin urethra" type chordee I according to D-H. All boys in this group were treated for urethroplasty with autologous buccal mucosal graft. Good results were obtained in 3 of 5 (60%). Successful outcome was achieved in both cases with "skin urethra" not previously treated. The results of our urethroplasty with buccal mucosa agree with those in literature. In the treatment of chordee without hypospadias, where it was necessary to reconstruct the urethra there was a constant problem of the shortage of local tissue, so we believe that buccal mucosa is a good choice.

Although surgical correction of dentomaxillofacial deformities has made great progress, the modern mode of orthognathic surgery, which is characterized by interdisplinary approach of oral surgeons and orthodontists, and by taking into account both facial appearances and the occlusions, has not been commonly carried out in China. Moreover, non-standard medical practice still exists in the treatment of patients with dentofacial deformities. Based on the relevant literatures and clinical experiences, we established the guideline of surgical correction for dentofacial deformities, hoping that it will play a regulatory and guiding role in carrying out orthognathic surgery in China.%牙颌面畸形是一种因颌面骨骼生长发育失调所引起的颜面形态异常与咬合关系错乱,大多需要采取手术进行矫正.尽管外科矫治牙颌面畸形的技术已取得长足进步,但以口腔颌面外科手术与口腔正畸科联合矫治,颜面外形与口颌系统功能同时兼顾为特点的现代正颌外科治疗模式在我国的开展并不普遍,在对牙颌面畸形患者的诊治中仍存在不规范医疗行为.为此,我们参考国内外相关文献并根据国内几家口腔医学院的诊疗经验,特制定了该指南,希望对开展正颌外科的临床工作起到规范与指导作用.

    Women with breast cancer often experience significant distress. Currently, there are no questionnaires aimed at identifying women's unique and possible changing indicators for distress in surgical continuity of care for breast cancer. We developed and tested three questionnaires specifically for this use. We first searched PubMed, CINAHL and PsycINFO to retrieve information on previously described indicators. Next, we conducted a focus group interview with 6 specialised nurses, who have extensive experience about consequences of breast cancer for women in surgical continuity of care. The questionnaire was tested on 18 women scheduled for breast cancer surgery. Subsequently, the women were debriefed to gain knowledge about comprehensibility, readability and relevance of items, and the time needed to complete the questionnaire. After adjustment, the questionnaires were field-tested concomitantly with a clinical study, which both consisted of a survey and an interview study. Three multi-item questionnaires were developed specific to different time points in surgical continuity of care. The questionnaires share a core of statements divided into seven sub-scales: emotional and physical situation, social condition, sexuality, body image, religion and organisational factors. Besides the core of statements, each questionnaire has different statements depending on the time point of surgical continuity of care when it was to be responded to. The questionnaires contain comprehensive items that can identify indicators for distress in individual women taking part in surgical continuity of care. The items were understandable and the time used for filling in the questionnaires was reasonable. Copyright © 2014 Elsevier Ltd. All rights reserved.

    ínicas of the University of São Paulo. The neural network was designed containing 3 layers. Sixty-eight patients were used in the training and validation set, and 27 in the test set. RESULTS: In the 68 patients used in the training and validation set, 37 had exotropia, and 31 esotropia. The backpropagation approach was used for training the neural network. A learning rate of 0.6, and a tolerance error of 0.05 were used. In the 27 patients used in the test set, 18 had exotropia, and 9 had esotropia. The efficacy of the neural network was analyzed using the average of the difference between the indication supplied by the network and the original indication. In patients with exotropia, the average error was 0.4 mm (±0.4, for recession of the lateral rectus muscle, and 0.3 mm (±0.3, for the resection of the medial rectus muscle. In the esotropia group, the average error was 0.2 mm (±0.2 for the recession of the medial rectus muscle, and 0.5 mm (±0.3 for resection of the lateral rectus muscle. CONCLUSION: As the artificial neural network can simulate a biological central nervous system, and is able to carry out cognitive tasks, it can be a viable option to help the surgical planning for strabismus correction.

    Hypothesis and aim. The large number of invalidating surgical interventions in patients suffering from lesions of the diabetic foot, the late recognition of the lesions and sometimes the wrongful interpretation of their severity, have made necessary a multi-parameter study of these types of patients and the elaboration of a therapeutic-prognostic index to guide the physician in adopting the adequate method of treatment. Starting with the therapeutic-prognostic index imagined by professor Traian Patrascu, we have elaborated a new therapeutic prognostic index, by adding new, statistically significant parameters, for the purpose of facilitating the surgical indication, depending on the lesion type. Methods. A number of 929 patients who were admitted at the Surgery Clinic of the “Dr. I. Cantacuzino” Hospital, between January 2013 and June 2014, have been analyzed, of whom 450 were evaluated retrospectively and 479 prospectively. Results. The new therapeutic prognostic index has been calculated for the retrospective lot, resulting into a concordance between the actual surgical intervention and the prognostic index of 79.4% and, for the patients evaluated prospectively, we have found a confirmation of the relation of 82.6% between the performed surgical intervention and the forecasted surgical intervention, by calculating the index. Discussion. The new therapeutic-prognostic index represents an easy method of establishing the therapeutic conduct of the patient suffering from lesions of the diabetic foot. It is of major use in preventing the execution of such surgical interventions that may be disproportionate compared to the severity of the lesions, especially in facilities where the pathology of the diabetic foot is less known.

    2009-11-01

    The success of organ preservation protocols in laryngeal cancer has led to an increase in the use of primary chemoradiation in both laryngeal and extralaryngeal sites, despite a paucity of randomized controlled clinical trial data comparing nonoperative treatment to the gold standard of surgery followed by postoperative radiation for adverse pathologic features for head and neck cancer, and an increasing recognition that the high surgical salvage rates enjoyed by laryngeal cancer patients do not translate to extralaryngeal sites. These data suggest that there is a need to apply more rigorous standards to the use of organ preservation strategies and offer an opportunity to review the role of primary surgery in head and neck cancer.

    2010-06-01

    Mandibulo-maxillary fixation (MMF) screws are inserted into the bony base of both jaws in the process of fracture realignment and immobilisation. The screw heads act as anchor points to fasten wire loops or rubber bands connecting the mandible to the maxilla. Traditional interdental chain-linked wiring or arch bar techniques provide the anchorage by attached cleats, hooks, or eyelets. In comparison to these tooth-borne appliances MMF screws facilitate and shorten the way to achieve intermaxillary fixation considerably. In addition, MMF screws help to reduce the hazards of glove perforation and wire stick injuries. On the downside, MMF screws are attributed with the risk of tooth root damage and a lack of versatility beyond the pure maintenance of occlusion such as stabilizing loose teeth or splinting fragments of the alveolar process. The surgical technique of MMF screws as well as the pros and cons of the clinical application are reviewed. The adequate screw placement to prevent serious tooth root injuries is still an issue to rethink and modify conceptual guidelines.

    The physiological and psychological stress that brain tumor patients undergo during the entire surgical experience can considerably affect several aspects of their hospitalization. The purpose of this study was to examine the effects of live music therapy on quality of life indicators, amount of medications administered and length of stay for persons receiving elective surgical procedures of the brain. Subjects (N = 27) were patients admitted for some type of surgical procedure of the brain. Subjects were randomly assigned to either the control group receiving no music intervention (n = 13) or the experimental group receiving pre and postoperative live music therapy sessions (n = 14). Anxiety, mood, pain, perception of hospitalization or procedure, relaxation, and stress were measured using a self-report Visual Analog Scale (VAS) for each of the variables. The documented administration of postoperative pain medications; the frequency, dosage, type, and how it was given was also compared between groups. Experimental subjects live and interactive music therapy sessions, including a pre-operative session and continuing with daily sessions until the patient was discharged home. Control subjects received routine hospital care without any music therapy intervention. Differences in experimental pretest and posttest scores were analyzed using a Wilcoxon Matched-Pairs Signed-Rank test. Results indicated statistically significant differences for 4 of the 6 quality of life measures: anxiety (p = .03), perception of hospitalization (p = .03), relaxation (p = .001), and stress (p = .001). No statistically significant differences were found for mood (p > .05) or pain (p > .05) levels. Administration amounts of nausea and pain medications were compared with a Two-Way ANOVA with One Repeated Measure resulting in no significant differences between groups and medications, F(1, 51) = 0.03; p > .05. Results indicate no significant differences between groups for length of stay (t = .97

    Full Text Available Objective: To evaluate the possibility of creating an effective antireflux mechanism without the need to create submucosal tunnel in surgical correction of vesicoureteric reflux. Materials and Methods: Ethical clearance was obtained from the institute ethical committee. The prospective experimental study was conducted on fresh postmortem specimens comprising of intact ureter-bladder-urethra of slaughtered lamb. Through perurethral tube, bladder distension revealed intact antireflux mechanism which disappeared following a cephalad slit of ureteric orifice. After intravesical advancement, mobilized ureters were anchored to the hiatus and the exposed detrusor along the proposed submucosal tunnel after stripping the bladder mucosa. Limited nonobstructed narrowing of the advanced ureteric ends was fashioned. After closure, bladder was distended and reflux was observed through proximal transected ureteric orifices with check cystogram. In second part of experiment, in a rectal reservoir, two intestinal segments as dilated ureters were implanted without creating submucosal tunnel, but anchoring the intrarectal segment to exposed submucosa. Intraluminal end of one segment was narrowed, while other left as such. Reservoir distension test was done to notice the status of reflux. In 24 months, 12 experiments were conducted. Results: In first part of experiment, successful antireflux mechanism was created in 11 ureters. In second part of experiment, reflux persisted in the ureteral segment implanted with obliquity but without distal nonobstructed narrowing, while there was no reflux in the ureteral segment with both obliquity and narrowing. Conclusion: Advancement and anchoring of the ureteral segment to the exposed detrusor with creation of nonobstructive and limited narrowing can create effective antireflux mechanism without the need to create submucosal tunnel.

    Evaluation of myocardial function is clinically challenging in dogs with degenerative mitral valve disease (DMVD). Although myocardial dysfunction is caused by pathologic degeneration, histopathologic progression is poorly understood. To characterize myocardial and pulmonary pathologic changes according to severity in dogs with naturally occurring DMVD, and to investigate whether or not pathologic degeneration is reflected by traditional clinical indices. One hundred and seventeen dogs with naturally occurring DMVD. Prospective observational study. Biopsied left atrium (LA), left ventricle (LV), and lung were evaluated histologically, and an attempt was made to correlate pathologic findings with clinical indices. Severe myocardial changes were observed in all International Small Animal Cardiac Health Council classes. In the lung, heart failure cell levels were significantly increased in class III patients (P fibrosis (P < .0001). In contrast, myocardial cells were more hypertrophied in the LV than in the LA (P < .0001). Left ventricular end-diastolic dimension (LVEDd) was associated with fatty replacement (P = .033, R(2) = 0.584) and myocardial vacuolization (P = .003, R(2) = 0.588) in the LA. In DMVD, although severe pathologic changes may be evident even in early stages, there may be pathologic discrepancy between the LA and the LV. Myocardial degeneration may be reflected by clinical indices such as LVEDd and EF. Copyright © 2015 The Authors.

    The aim of the study is an estimation of the uncertainty in flood indices introduced by bias correction of climate model variables in ten catchments in Poland. A simulation approach is used to obtain daily flows in catchments under changing climatic conditions, following the RCP4.5 and RCP8.5 emission scenarios. Climate projections were obtained from the EURO-CORDEX initiative, and time series of precipitation and air temperature from different RCM/GCMs for the periods: 1971-2000, 2021-2050 and 2071-2100 were used. The climate model outputs in the Poland area are highly biased; therefore, additional post processing in the form of bias correction of precipitation and temperature is needed. In this work we used four versions of the quantile mapping method (empirical quantile mapping, and three distribution based mappings: double gamma, single gamma and Birnbaum-Sanders) for correction of the precipitation time series and one method for air temperature correction (empirical quantile method). The HBV rainfall-runoff catchment-based model is used to estimate future flow time series. The models are calibrated using the available precipitation, air temperature, and flow observations for the period 1971-2000. Model performance is evaluated using observed data for the period 2001-2010. We also verify performance using the EURO-CORDEX simulations for the reference period (1971-2000), both with and without bias correction of the RCM/GCM outputs. Finally, the models are run for the future climate simulated by the RCM/GCM models for the years: 2021-2050 and 2071-2100. Changes in the mean annual flood and in flood quantiles are analysed and the effect of bias correction on the estimated changes is also considered. The results indicate substantial differences between climate models and catchments. The regional variability has a close relationship with the flood regime type. Catchments where high flows are expected to increase have a rainfall-dominated flood regime in the current

    Patellar tendon shortening procedure within single event multilevel surgeries was shown to improve crouch gait in Cerebral Palsy (CP) patients. However, one of the drawbacks associated to the correction of flexed knee gait may be increased pelvic anterior tilt with compensatory lumbar lordosis. Which CP patients are at risk for excessive anterior pelvic tilt following correction of flexed knee gait including patellar tendon shortening? 32 patients with CP between 8 and 18 years GMFCS I&II were included. They received patellar tendon shortenings within multilevel surgery. Patients with concomitant knee flexor lengthening were excluded. Gait analysis and clinical testing was performed pre- and 24.1 (SD=1.9) months postoperatively. Patients were subdivided into more/less than 5° increase in anterior pelvic tilt. Preoperative measures indicating m. rectus and m. psoas shortness, knee flexor over-length, hip extensor and abdominal muscle weakness and equinus gait were compared between groups. Stepwise multilinear regression of the response value increase in pelvic tilt during stance phase was performed from parameters that were significantly different between groups. 34% of patients showed more than 5° increased pelvic anterior tilt postoperatively. Best predictors for anterior pelvic tilt from preoperative measures were increased m. rectus tone and reduced hip extension during walking that explained together 39% of the variance in increase of anterior pelvic tilt. Every third patient showed considerable increased pelvic tilt following surgery of flexed knee gait. In particular patients with preoperative higher muscle tone in m. rectus and lower hip extension during walking were at risk and both features need to be addressed in the therapy.

    Thyroid gland tumors represent 1% of malignant tumors. In Italy their incidence is in constant growth. The aggressiveness depends on the histological type. The relative non-aggressive grade of different forms of tumors is the basis for discussing the treatment of choice: total thyroidectomy vs lobectomy with or without lymphadenectomy of the sixth level in the absence of metastasis. Authors report about their experience, and they advocate, given the high percentage of multicentric forms, total thyroidectomy as treatment of choice.

    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced corneal ectasia, haze, anisometropy with monovision, regression of effect, decline in uncorrected distance vision, and the inherent risks with invasive techniques, limiting the development of an ideal solution. The correction of the presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. The purpose of this paper is to provide an update about current procedures available for presbyopia correction, their advantages, and disadvantages.Keywords: presbyopia, surgical correction, treatment

    Metal endoprostheses and internal fixation devices cause significant artifacts on CT after limb salvage surgery; positron emission tomography (PET) images should be evaluated for artifacts. (1) To describe [F-18]2-fluoro-2-deoxyglucose (FDG) PET uptake patterns after limb salvage surgery. (2) To determine whether metal endoprostheses and fixation hardware cause significant artifacts on CT attenuation-corrected PET that interfere with diagnostic use of PET/CT after limb salvage surgery. We reviewed 92 studies from 18 patients ages 5-21 years. Diagnoses were osteogenic sarcoma in 14, Ewing sarcoma in 3, and malignant peripheral nerve sheath tumor originating in bone in 1. Nine patients had distal femur/knee endoprostheses, five had lower-extremity bone allografts secured by large metal plates and four had upper-extremity limb salvage procedures. Maximum standardized uptake value was calculated at lower-extremity soft-tissue-endoprosthesis interfaces. In 15 patients with PET/CT imaging, the first PET/CT scan after limb salvage surgery was reviewed for metal artifacts on CT images and for artifacts at locations on PET corresponding to the CT metal artifacts. Increased FDG uptake was consistently present at soft-tissue interfaces with endoprostheses, allografts and internal fixation devices, with little or no FDG uptake at cemented endoprosthesis-bone interfaces. Maximum standardized uptake value at margins of femur/knee endoprostheses ranged from 1.4 to 5.7. In four patients with distal femur/knee endoprostheses, minimal artifact was noted on attenuation-corrected PET images, but image interpretation was not affected. In the other 11 patients who had CT attenuation correction, we detected no artifacts caused by the attenuation correction. CT attenuation correction did not cause artifacts that affected interpretation of attenuation-corrected PET images. (orig.)

    Full Text Available For patients whose orthodontic problems are so severe that neither growth modification nor camouflage offers a solution, surgery to realign the jaws or reposition dentoalveolar segments is the only possible treatment. Surgery is not a substitute for orthodontics in these patients. Instead, it must be properly coordinated with orthodontics and other dental treatments to achieve good overall results. Dramatic progress in recent years has made it possible for combined surgical orthodontic treatment to be carried out successfully for patients with a severe dentofacial problem of any type. This case report provides an overview of the current treatment methodology in managing a combination of asymmetrical mandibular prognathism and vertical maxillary excess.

    Full Text Available Abstract Background Although most idiopathic scoliosis patients subject to conservative treatment in daily clinical practice, there have been no ideal methods to evaluate the spinal flexibility for the patients who are scheduled the brace treatment. The purpose of this study was to investigate the value of hanging total spine x-ray to estimate the indicative correction angle by brace wearing in idiopathic scoliosis patients. Methods One hundred seventy-six consecutive patients with idiopathic scoliosis who were newly prescribed the Osaka Medical College (OMC brace were studied. The study included 14 boys and 162 girls with a mean age of 13 years and 1 month. The type of curves consisted of 62 thoracic, 23 thoracolumbar, 22 lumbar, 42 double major, 14 double thoracic, and 13 triple curve pattern. We compared the Cobb angles on initial brace wearing (BA and in hanging position (HA. Of those, 108 patients who had main thoracic curves were selected and evaluated the corrective ability of OMC brace. These subjects were divided into three groups according to the relation between BA and HA (BA HA group, and then, maturity was compared among them. Results The average Cobb angle in upright position (UA of all cases was 31.0 ± 7.8°. The average BA and HA of all cases were 20.3 ± 9.5° and 21.1 ± 8.4°, respectively. The average chronological age was lowest in BA Conclusions The use of hanging total spine x-ray served as a useful tool to estimate the degree of correction possible curve within the OMC brace for main thoracic curve in idiopathic scoliosis. Maturity had some influence on the correlation between HA and BA. Namely, in immature patients, HA tended to be larger than BA. In contrast, in mature patients, HA had a tendency to be smaller than BA. With consideration for spinal flexibility based on maturity, in mature patients, larger BA than HA may be allowed. However, in immature patients, smaller BA than HA should be aimed.

    Nutrition has been highlighted as a potential factor in Alzheimer's disease (AD) risk and decline and has been investigated as a therapeutic target. Broad-based combination diet therapies have the potential to simultaneously effect numerous protective and corrective processes, both directly (e.g., neuroprotection) and indirectly (e.g., improved vascular health). Here we administered either normal mouse chow with a broad-based nutritional supplement or mouse chow alone to aged male and female 3xTg mice and wildtype (WT) controls. After approximately 4 months of feeding, mice were given a battery of cognitive tasks and then injected with a radiolabeled glucose analog. Brains were assessed for differences in regional glucose uptake and mitochondrial cytochrome oxidase activity, AD pathology, and inflammatory markers. Supplementation induced behavioral changes in the 3xTg, but not WT, mice, and the mode of these changes was influenced by sex. Subsequent analyses indicated that differential response to supplementation by male and female 3xTg mice highlighted brain regional strategies for the preservation of function. Several regions involved have been shown to mediate responses to steroid hormones, indicating a mechanism for sex-based vulnerability. Thus, these findings may have broad implications for the human response to future therapeutics.

    Cadaveric biomechanical study. To determine the degree of segmental correction that can be achieved through lateral transpsoas approach by varying cage angle and adding anterior longitudinal ligament (ALL) release and posterior element resection. Lordotic cage insertion through the lateral transpsoas approach is being used increasingly for restoration of sagittal alignment. However, the degree of correction achieved by varying cage angle and ALL release and posterior element resection is not well defined. Thirteen lumbar motion segments between L1 and L5 were dissected into single motion segments. Segmental angles and disk heights were measured under both 50 N and 500 N compressive loads under the following conditions: intact specimen, discectomy (collapsed disk simulation), insertion of parallel cage, 10° cage, 30° cage with ALL release, 30° cage with ALL release and spinous process (SP) resection, 30° cage with ALL release, SP resection, facetectomy, and compression with pedicle screws. Segmental lordosis was not increased by either parallel or 10° cages as compared with intact disks, and contributed small amounts of lordosis when compared with the collapsed disk condition. Placement of 30° cages with ALL release increased segmental lordosis by 10.5°. Adding SP resection increased lordosis to 12.4°. Facetectomy and compression with pedicle screws further increased lordosis to approximately 26°. No interventions resulted in a decrease in either anterior or posterior disk height. Insertion of a parallel or 10° cage has little effect on lordosis. A 30° cage insertion with ALL release resulted in a modest increase in lordosis (10.5°). The addition of SP resection and facetectomy was needed to obtain a larger amount of correction (26°). None of the cages, including the 30° lordotic cage, caused a decrease in posterior disk height suggesting hyperlordotic cages do not cause foraminal stenosis. N/A.

    Objective To evaluate the clinical outcomes of posterior surgical corrective methods for ankylosing spondylitic kyphosis. Methods From June 2003 to June 2008, 21 cases of ankylosing spondylitic kyphosis received posterior surgical correction. There were 17 male and 4 female, and the average age was 39. 5 years (range, 20 to 57 years). The total spine X-ray and CT were used to evaluate sagittal balance and thoracolumbar spine kyphosis angle, and chin brow-vertical angle was obtained from clinical lateral photograph. The surgical goal was to correct sagittal imbalance and chin brow-vertical angle.The simulated osteotomy was performed in computer before surgery to determine the correction methods. The surgical methods included: 16 cases of monosegmental closing osteotomy correction, 3 cases of anterior opening-posterior closing osteotomy correction, and 2 cases of combined pedicle subtraction osteotomy in thoracolumbar spine and Smith-Peterson osteotomy in lumbar spine. All patients were followed up after surgery, and the improvement of sagittal imbalance, chin brow-vertical angle and thoracolumbar spine kyphosis angle were assessed. The symptoms relief and satisfied rate were also evaluated. Results The average operation time was 4.4hours, and the average blood loss was 1770 ml. Before surgery, the average thoracolumbar kyphosis angle was 62.1°,the average anterior shift of C7 plumb line was 172. 9 mm, and theaverage chin brow-vertical angle was 34. 9°. The average follow-up was 28. 8 months after surgery. The average correction rate of thoracolumbar kyphosis angle was 60%, the average improvement rate of anterior shift of C7 plumb line was 64%, and the average correction rate of chin brow-vertical angle was 98%. The improvement rate of back pain was 64% during follow-up. The total surgical satisfactory rate was 95%.Conclusion Based on the simulated osteotomy in computer before surgery, according to the characteristics of ankylosing spondylitic kyphosis, different

    Recent studies on the use of spectral indices have involved radiometric correction as a prerequisite. However, study on the effect of radiometric correction level on the accuracy of biophysical parameters’ estimate is still rare in Indonesia. This study tried to investigate the influence of various radiometric correction levels and the number of vegetation strata on the accuracy of vegetation density estimates using NDVI, MSAVI2 and GEMI of Landsat 8 OLI. In this study, the dataset covering vegetated area in Wonosari, Gunung Kidul Regency, Indonesia was processed radiometrically using eight different methods, i.e. spectral radiance, at sensor reflectance, sun elevation correction, histogram adjustments using original DN, spectal radiance, at sensor reflectance, and sun position correction respectively, as well as dark object subtraction (DOS). Every image with specific correction level was then transformed using the aforementioned indices, in order correlate with the field-measured canopy density. The analysis were carried out by considering the number of canopy layers. This found that different radiometric correction methods resulted canopy density estimates with different accuracies. The number of canopy strata also played an important role. Every vegetation index transformation performed its best accuracy by using different radiometric correction method and different number of canopy layers.

  3. A Novel Approach to the Surgical Treatment of Lumbar Disc Herniations: Indications of Simple Discectomy and Posterior Transpedicular Dynamic Stabilization Based on Carragee Classification

    2013-01-01

    Full Text Available Surgery of lumbar disc herniation is still a problem since Mixter and Barr. Main trouble is dissatisfaction after the operation. Today there is a debate on surgical or conservative treatment despite spending great effort to provide patients with satisfaction. The main problem is segmental instability, and the minimally invasive approach via microscope or endoscope is not necessarily appropriate solution for all cases. Microsurgery or endoscopy would be appropriate for the treatment of Carragee type I and type III herniations. On the other hand in Carragee type II and type IV herniations that are prone to develop recurrent disc herniation and segmental instability, the minimal invasive techniques might be insufficient to achieve satisfactory results. The posterior transpedicular dynamic stabilization method might be a good solution to prevent or diminish the recurrent disc herniation and development of segmental instability. In this study we present our experience in the surgical treatment of disc herniations.

    2006-12-01

    Full Text Available Abstract Background The current method of treatment for persistent internal rotation due to the medial rotation contracture in patients with obstetric brachial plexus injury is humeral derotational osteotomy. While this procedure places the arm in a more functional position, it does not attend to the abnormal glenohumeral joint. Poor positioning of the humeral head secondary to elevation and rotation of the scapula and elongated acromion impingement causes functional limitations which are not addressed by derotation of the humerus. Progressive dislocation, caused by the abnormal positioning and shape of the scapula and clavicle, needs to be treated more directly. Methods Four patients with Scapular Hypoplasia, Elevation And Rotation (SHEAR deformity who had undergone unsuccessful humeral osteotomies to treat internal rotation underwent acromion and clavicular osteotomy, ostectomy of the superomedial border of the scapula and posterior capsulorrhaphy in order to relieve the torsion developed in the acromio-clavicular triangle by persistent asymmetric muscle action and medial rotation contracture. Results Clinical examination shows significant improvement in the functional movement possible for these four children as assessed by the modified Mallet scoring, definitely improving on what was achieved by humeral osteotomy. Conclusion These results reveal the importance of recognizing the presence of scapular hypoplasia, elevation and rotation deformity before deciding on a treatment plan. The Triangle Tilt procedure aims to relieve the forces acting on the shoulder joint and improve the situation of the humeral head in the glenoid. Improvement in glenohumeral positioning should allow for better functional movements of the shoulder, which was seen in all four patients. These dramatic improvements were only possible once the glenohumeral deformity was directly addressed surgically.

    Full Text Available Objective.To assess the performance of a simple correction method for nutritional status estimates in children under five years of age when exact age is not available from the data. Materials and methods. The proposed method was ba- sed on the assumption of symmetry of age distributions within a given month of age and validated in a large population-based survey sample of Mexican preschool children. Results. The main distributional assumption was consistent with the data. All prevalence estimates derived from the correction method showed no statistically significant bias. In contrast, failing to correct attained age resulted in an underestimation of stunting in general and an overestimation of overweight or obesity among the youngest. Conclusions. The proposed method performed remarkably well in terms of bias correction of estimates and could be easily applied in situations in which either birth or interview dates are not available from the data.

    Objective To summarize the experience with surgical correction of tetralogy of Fallot in adults over 40 years of age. Methods From November 1985 to July 2008, 9 male and 11 female patients aged 41-53 years (mean 46.3±3.5 years) underwent total surgical correction for tetralogy of Fallot. Twelve patients had preoperative NYHA class Ⅲ cardiac function. The common comorbidities included infective endocarditis, cerebral abscess, cerebral infarction, renal dysfunction, and tricuspid insufficiency. Surgical corrections were carried out at the anatomical or physiological level. Results Nineteen patients received right ventriculotomy to relieve right ventricular outflow obstruction and for ventricular septal defect closure, and 1 patient had Fontan operation. Two patients died after the surgery for heart failure and ventricular fibrillation. The average cardiopulmonary bypass time, aortic clamp time, and postoperative ventilation time was 142.9±36.3 min, 89.9±25.1 min, and 72.0 ±17.5 h, respectively. Postoperative low cardiac output syndrome occurred in 5 cases, septic shock in 1 case, secondary renal failur e in 1 case, and bleeding in 2 cases. Echocardiography showed a significant postoperative reduction of the mean right ventricular outflow tract velocity from 4.29 ±1.36 m/s to 2.13 ±0.83 m/s (P<0.01); the right ventricular longitudinal dimension exhibited no significant changes postoperatively (57.1 ± 6.7 mm vs 55.1 ± 7.0 mm, P=0.65). Conclusion Surgical correction of the tetralogy of Fallot in patients over 40 years is highly risky and requires appropriate management of cardiac failure, careful myocardial protection, and thorough intracardiac lesion correction to decrease surgical complications.%目的 40岁以上法乐氏四联症(TOF)多术前合并症及术后并发症,手术风险大,本文通过总结20例40岁以上TOF外科根治手术,探讨该类患者外科治疗相关经验.方法 1985年11月~2008年7月收治41岁以上成年TOF病人20

    Full Text Available Background. Primary osteoarthritis of the elbow is a debilitating disease with an overall incidence of about 2%. Pain and reduced motion (ROM lead to disability and loss of functional independence. Purpose. To critically review the literature on patient-related important functional outcomes (pain, ROMs and functional recovery after surgery for primary OA of the elbow, utilizing the 2011 OCEBM levels of evidence. Design. A literature synthesis. Results. Twenty-six articles satisfied the inclusion and exclusion criteria; 25 of the studies were at level IV evidence, and 1 at level III. All three surgical techniques led to improvement in pain, ROM, and functional recovery in the short- and medium-term follow-up. Long-term follow-up results, available only for open joint debridement, showed recurrence of osteoarthritic signs on X-ray with minimal loss of motion. Recently, there seems to be an increased focus on arthroscopic debridement. Conclusion. The quality of research addressing surgical interventions is very low, including total elbow arthroplasty (TEA. However, the evidence concurs that open and arthroscopic joint debridement can improve function in patients with moderate-to-severe OA of the elbow. TEA is reserved for treating severe joint destruction, mostly for elderly individuals with low physical demands when other intervention options have failed.

    Reliable Digit Span (RDS) is a measure of effort derived from the Digit Span subtest of the Wechsler intelligence scales. Some authors have suggested that the age-corrected scaled score provides a more accurate measure of effort than RDS. This study examined the relative diagnostic accuracy of the traditional RDS, an extended RDS including the new Sequencing task from the Wechsler Adult Intelligence Scale-IV, and the age-corrected scaled score, relative to performance validity as determined by the Test of Memory Malingering. Data were collected from 138 Veterans seen in a traumatic brain injury clinic. The traditional RDS (≤ 7), revised RDS (≤ 11), and Digit Span age-corrected scaled score ( ≤ 6) had respective sensitivities of 39%, 39%, and 33%, and respective specificities of 82%, 89%, and 91%. Of these indices, revised RDS and the Digit Span age-corrected scaled score provide the most accurate measure of performance validity among the three measures.

    Full Text Available Today subclinical Cushing's syndrome is the most widespread variant of hormonal activity of incidentaloma's hormonal activity. This pathology is defined as a mild intensity autonomous cortisol hypersecretion, not causing specific clinical signs of hypercorticism, but detectable biochemically as derangements of the hypothalamic-pituitary-adrenal axis function. Some clinical symptomatology of metabolic syndrome, such as obesity, impaired carbohydrate metabolism and hypertension, are peculiar to subclinical hypercorticism more than to population. As a result all these symptomatology could lead to increasing cardiovascular risk. Till now there isn't a definite opinion about the need of surgical treatment of present pathology. But there is evidence, that after removing of incidentalomas clinical symptomatology of metabolic syndrome are improving. For understanding all possible risks, connected with subclinical hypercorticism, it's necessary to study the origins of their arising and present about the most adequate screening tests.

    Objective To simulate different anterior and posterior correction strategies using finite element model of Lenke 2 type adolescent idiopathic scoliosis(AlS), in an effort to seek the optimal surgical protocol. Methods The finite element model of Lenke 2 type AIS was established and used to simulate five surgical strategies. The effectiveness and shoulder balance parameters were compared among different surgical approaches. Results The coronary proximal thoracic(PT) Cobb angle and corrective rates of the five surgical strategies were 21. 5(44. 8%), 26.5(32. 1%), 28. 1(27.9%), 34. 1(12.5%), and 32(17. 9%). The corrective rates for the main thoracic curves were not significantly different among the five strategies, and the physiological sagittal configuration was maintained. Postoperative radiographic shoulder balance parameters were increased for all five surgical protocols. Except for strategy A(posterior fusion from T2 to T11 ), other four strategy achieved the following outcomes! coracoid height difference>9 mm, elavical angle>2. 5° and clavicular tilt angle difference>4. 5° . Conclusion Simulation of posterior correction and fusion to T2 including both thoracic curve can achieve excellent three-dimensional shoulder imbalance slight to moderate degrees.%目的 利用建立的Lenke 2型青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)三维有限元模型,分别仿真模拟前路、后路手术矫形操作,探讨其最佳手术方案.方法 建立Lenke 2型AIS的有限元模型,分别模拟前路和后路共5种不同的矫形方案,比较不同手术方案的矫形效果和双肩平衡参数的变化.结果 5种不同矫形方案有限元模拟术后的上胸弯冠状面Cobb角和矫形率分别为:21.5(44.8%)、26.5(32.1%)、28.1(27.9%)、34.1(12.5%)、32(17.9%),各矫形方案的主胸弯矫正率无明显差别.胸椎矢状面生理后凸得以维持.5种矫形方案术后各双肩平衡影像学参数较术前有所升高,除方

    Vertigo is not a well defined symptom but a heterogenous entity diagnosed and treated mainly by otolaryngologists, neurologists, internal medicine and primary care physicians. Most vertigo syndroms have a good prognosis and management is predominantly conservative, whereas the need for surgical therapy is rare, but for a subset of patients often the only remaining option. In this paper, we describe the development of surgical therapy for hydropic inner ear diseases, Menière disease, dehiscence syndroms, perilymphatic fistulas, and benign paroxysmal vertigo. At the end, we shortly introduce the most recent development of vestibular implants. Surgical vestibular therapy is still indicated for selected patients nowadays when conservative options did not reduce symptoms and patients are still suffering. Success depends on the correct diagnosis and indication for the different procedures going along with an adequate patient selection. In regard to the invasiveness and the possible risks due to the surgery, in depth individual counselling is necessary. Ablative and destructive surgical procedures usually achieve a successful vertigo control, but go along with a high risk for hearing loss. Therefore, residual hearing has to be included in the decission making process for a surgical therapy. © Georg Thieme Verlag KG Stuttgart · New York.

  1. Fatal Renal Failure in a Spinal Cord Injury Patient with Vesicoureteric Reflux Who Underwent Repeated Ureteric Reimplantations Unsuccessfully: Treatment Should Focus on Abolition of High Intravesical Pressures rather than Surgical Correction of Reflux

    2012-01-01

    Full Text Available A 29-year-old man developed paraplegia at T-10 level due to road traffic accident in 1972. Both kidneys were normal and showed good function on intravenous urography. Division of external urethral sphincter was performed in 1973. In 1974, cystogram showed retrograde filling of left renal tract, which was hydronephrotic. Left ureteric reimplantation was performed. Following surgery, cystogram revealed marked retrograde filling of left renal tract as before. Penile sheath drainage was continued. In 1981, intravenous urography revealed bilateral severe hydronephrosis. Left ureteric reimplantation was performed again in 1983. Blood pressure was 220/140 mm Hg; this patient was prescribed atenolol. Cystogram showed gross left vesicoureteral reflux. Intermittent catheterisation was commenced in 2001. In 2007, proteinuria was 860 mg/day. This patient developed progressive renal failure and expired in 2012. In a spinal cord injury patient with vesicoureteral reflux, the treatment should focus on abolition of high intravesical pressures rather than surgical correction of vesicoureteric reflux. Detrusor hyperactivity and high intravesical pressures are the basic causes for vesicoureteral reflux in spinal cord injury patients. Therefore, it is important to manage spinal cord injury patients with neuropathic bladder by intermittent catheterisations along with antimuscarinic drug therapy in order to abolish high detrusor pressures and prevent vesicoureteral reflux. Angiotensin-converting enzyme inhibitors or angiotensin-receptor-blocking agents should be prescribed even in the absence of hypertension when a spinal cord injury patient develops vesicoureteral reflux and proteinuria.

    OBJECTIVE: To determine whether near infrared spectroscopic measurement of tissue pH and Po2 has sufficient accuracy to assess variation in tissue perfusion resulting from changes in blood pressure and metabolic demand during cardiopulmonary bypass. DESIGN: Prospective clinical study. SETTING: Academic medical center. SUBJECTS: Eighteen elective cardiac surgical patients. INTERVENTION: Cardiac surgery under cardiopulmonary bypass. MEASUREMENTS AND MAIN RESULTS: A near infrared spectroscopic fiber optic probe was placed over the hypothenar eminence. Reference Po2 and pH sensors were inserted in the abductor digiti minimi (V). Data were collected every 30 secs during surgery and for 6 hrs following cardiopulmonary bypass. Calibration equations developed from one third of the data were used with the remaining data to investigate sensitivity of the near infrared spectroscopic measurement to physiologic changes resulting from cardiopulmonary bypass. Near infrared spectroscopic and reference pH and Po2 measurements were compared for each subject using standard error of prediction. Near infrared spectroscopic pH and Po2 at baseline were compared with values during cardiopulmonary bypass just before rewarming commenced (hypotensive, hypothermic), after rewarming (hypotensive, normothermic) just before discontinuation of cardiopulmonary bypass, and at 6 hrs following cardiopulmonary bypass (normotensive, normothermic) using mixed-model analysis of variance. Near infrared spectroscopic pH and Po2 were well correlated with the invasive measurement of pH (R2 =.84) and Po2 (R 2 =.66) with an average standard error of prediction of 0.022 +/- 0.008 pH units and 6 +/- 3 mm Hg, respectively. The average difference between the invasive and near infrared spectroscopic measurement was near zero for both the pH and Po2 measurements. Near infrared spectroscopic Po2 significantly decreased 50% on initiation of cardiopulmonary bypass and remained depressed throughout the bypass and

    banding in order to control congestive heart failure and to prevent pulmonary vascular disease. Twenty-three patients were male and 17 were female. The mean age was 6 months (20 days to 17 months. The preoperative diagnosis were: ventricular septal defect (22, atrioventricular canal (6, double outlet right ventricle (2, tricuspid atresia (2, transposition of the great arteries (3, truncus arteriosus (2, single ventricle (1 and complexes pathologies (2. The pulmonary banding was carried out under control of the pulmonary artery pressure. Two patients (5 per cent died on the immediate postoperative period: one patient in atrioventricular block and another in sepsis. One patient died of pneumonia on the late postoperative period. The remaining patients had a satisfactory evolution, increasing 400g of weight monthly. Thirteen patients were submitted to hemodynamic studies on the postoperative period (mean 21 months. Important reduction in pulmonary pressures and flows were then observed, including in five cases with A-V canal. Thirteen patients were reoperated on to correct their underlying defects one year after the banding. Then, one patient died in the immediate postoperative phase and another on the late phase. One of the six patients with A-V canal died on the immediate postoperative period and the others were reoperated for correction of the defects, with good results.

    The etiology of morbid obesity is multifactorial and is related to inheritance, physiology, metabolism, sociocultural, behavioral, and psychological factors. In China, the incidence of obesity is increasing with the improvement of the standard of living each year. The USA is known as the nation that has a high prevalence of overweight and obese individuals, as indicated from the Nutrition and Health Status report. Obesity in China is a growing phenomenon that cannot be ignored. In this paper, we review the relatively new concept of bariatric surgery in China.

    2006-11-01

    The relationship between parasites and environmental stress were studied in two tropical coastal lagoons of Northwest Mexico: Urias estuary (highly polluted) and Teacapan estuary (slightly polluted). Metazoan parasites were examined in 292 white mullet (Mugil curema) specimens collected bimonthly during a year from both systems. Haliotrema mugilinus, Metamicrocotyla macracantha, Ergasilus sp., Caligus sp., Holobomolochus sp., and Lernaeopodidae were found in gills, while Contracaecum sp. larvae III was found liver, hepatic portal vein and kidneys. Ecological indices were influenced by the slightly higher number of parasitic species in Urias compared to Teacapan, as well as the clear dominance of two species: Ergasilus sp. and Contracaecum sp. in both systems. In fact, Ergasilus sp. showed considerably higher abundance in Urias, possibly indicating that its success was a result of adverse conditions affecting the host, while Contracaecum sp showed higher abundances in Teacapan, suggesting that the environmental conditions occurring in Urias could have produced negative impacts on the nematode's infective potential.

    Tuberculosis (TB) is a re-emerging health problem in developed countries. This paper is part of large guidelines on the global management of TB in children, by a group of scientific societies. It describes the indications to hospitalization of children with suspected or diagnosed TB, the isolation measures, hospital discharge, and re-admission into the community. Using the Consensus Conference method, relevant publications in English were identified by means of a systematic review of MEDLINE and the Cochrane Database of Systematic Reviews from their inception until 31 December 2014. Available data on indications to hospitalization were mainly indirect and largely derived from observational studies. They include: (1) host-related risk factors, the main being age logistic conditions. The latter are based on opinion and depend on local conditions. Analysis of the literature showed that patients hospitalized with suspected pulmonary TB should be put in precautionary respiratory isolation regardless of their age while they await diagnosis. The general conditions for re-admission into the community are at least 14 days of effective treatment and negative microscopic tests of 3 consecutive samples in previously microscopically positive patients. This is the first paper that provides indications to hospitalization of children with TB. Most recommendations are generally applicable in all developed countries. Some might need an adaptation to local setting, epidemiological, parameters, and availability of specific health-care facilities.

    Full Text Available To investigate whether sensorimotor control of the hand could be an outcome indicator after carpal tunnel release (CTR, this work examined changes in the results of patients' manual tactile test (MTT, pinch-holding-up activity (PHUA, two-point discrimination (2PD and Semmes-Weinstein monofilament (SWM tests. Participants included 30 predominantly sensory neuropathy CTS patients, as confirmed by a nerve conduction study. The MTT, precision pinch performance in PHUA and traditional sensibility (2PD and SWM tests were used to examine different aspects of sensory status at the time-points of two weeks before operation and one month post-operation, with a single-blind design. The results showed significant improvements in the sensory function as detected by the 2PD and SWM tests (p0.5, p<0.01 are better than that of two-point discrimination test (effect size<0.5, p<0.001. However, pinch strength saw a decline compared to baseline with a moderate effect sizes (effect size = 0.7, p<0.001. This cohort study found that the MTT and PHUA test can both meet all the statistical criteria with regard to assessing treatment outcomes for patients with CTS. In addition, the results of this work provide clinicians with the information that the sensorimotor functions of the hands, as assessed by MTT and PHUA, are responsive to clinical changes due to CTR.

    Improving patient safety was a strong motivation behind duty hour regulations implemented by Accreditation Council for Graduate Medical Education on July 1, 2003. We investigated whether rates of patient safety indicators (PSIs) changed after these reforms. Observational study of patients admitted to Veterans Health Administration (VA) (N = 826,047) and Medicare (N = 13,367,273) acute-care hospitals from July 1, 2000 to June 30, 2005. We examined changes in patient safety events in more versus less teaching-intensive hospitals before (2000-2003) and after (2003-2005) duty hour reform, using conditional logistic regression, adjusting for patient age, gender, comorbidities, secular trends, baseline severity, and hospital site. Ten PSIs were aggregated into 3 composite measures based on factor analyses: "Continuity of Care," "Technical Care," and "Other" composites. Continuity of Care composite rates showed no significant changes postreform in hospitals of different teaching intensity in either VA or Medicare. In the VA, there were no significant changes postreform for the technical care composite. In Medicare, the odds of a Technical Care PSI event in more versus less teaching-intensive hospitals in postreform year 1 were 1.12 (95% CI; 1.01-1.25); there were no significant relative changes in postreform year 2. Other composite rates increased in VA in postreform year 2 in more versus less teaching-intensive hospitals (odds ratio, 1.63; 95% CI; 1.10-2.41), but not in Medicare in either postreform year. Duty hour reform had no systematic impact on PSI rates. In the few cases where there were statistically significant increases in the relative odds of developing a PSI, the magnitude of the absolute increases were too small to be clinically meaningful.

    Traditionally, anesthesiologists have relied on nonspecific subjective and objective physical signs to assess patients' comfort level and depth of anesthesia. Commercial development of electrical monitors, which use low- and high-frequency electroencephalogram (EEG) signals, have been developed to enhance the assessment of patients' level of consciousness. Multiple studies have shown that monitoring patients' consciousness levels can help in reducing drug consumption, anesthesia-related adverse events, and recovery time. This clinical study will provide information by simultaneously comparing the performance of the SNAP II (a single-channel EEG device) and the bispectral index (BIS) VISTA (a dual-channel EEG device) by assessing their efficacy in monitoring different anesthetic states in patients undergoing general anesthesia. The primary objective of this study is to establish the range of index values for the SNAP II corresponding to each anesthetic state (preinduction, loss of response, maintenance, first purposeful response, and extubation). The secondary objectives will assess the range of index values for BIS VISTA corresponding to each anesthetic state compared to published BIS VISTA range information, and estimate the area under the curve, sensitivity, and specificity for both devices. This is a multicenter, prospective, double-arm, parallel assignment, single-blind study involving patients undergoing elective surgery that requires general anesthesia. The study will include 40 patients and will be conducted at the following sites: The Ohio State University Medical Center (Columbus, OH); Northwestern University Prentice Women's Hospital (Chicago, IL); and University of Miami Jackson Memorial Hospital (Miami, FL). The study will assess the predictive value of SNAP II versus BIS VISTA indices at various anesthetic states in patients undergoing general anesthesia (preinduction, loss of response, maintenance, first purposeful response, and extubation).

    Background Traditionally, anesthesiologists have relied on nonspecific subjective and objective physical signs to assess patients’ comfort level and depth of anesthesia. Commercial development of electrical monitors, which use low- and high-frequency electroencephalogram (EEG) signals, have been developed to enhance the assessment of patients’ level of consciousness. Multiple studies have shown that monitoring patients’ consciousness levels can help in reducing drug consumption, anesthesia-related adverse events, and recovery time. This clinical study will provide information by simultaneously comparing the performance of the SNAP II (a single-channel EEG device) and the bispectral index (BIS) VISTA (a dual-channel EEG device) by assessing their efficacy in monitoring different anesthetic states in patients undergoing general anesthesia. Objective The primary objective of this study is to establish the range of index values for the SNAP II corresponding to each anesthetic state (preinduction, loss of response, maintenance, first purposeful response, and extubation). The secondary objectives will assess the range of index values for BIS VISTA corresponding to each anesthetic state compared to published BIS VISTA range information, and estimate the area under the curve, sensitivity, and specificity for both devices. Methods This is a multicenter, prospective, double-arm, parallel assignment, single-blind study involving patients undergoing elective surgery that requires general anesthesia. The study will include 40 patients and will be conducted at the following sites: The Ohio State University Medical Center (Columbus, OH); Northwestern University Prentice Women's Hospital (Chicago, IL); and University of Miami Jackson Memorial Hospital (Miami, FL). The study will assess the predictive value of SNAP II versus BIS VISTA indices at various anesthetic states in patients undergoing general anesthesia (preinduction, loss of response, maintenance, first purposeful

    Full Text Available Empyema thoracis can produce significant morbidity in children if inadequately treated. Correct evaluation of the stage of the disease, the clinical condition of the child and proper assessment of the response to conservative treatment is crucial in deciding the mode of further surgical intervention. This ranges from intercostal chest tube drainage and video-assisted thoracoscopic surgery to open decortication. Surgical decortication becomes mandatory in neglected cases; it gives very gratifying results ameliorating the disease rapidly and is well tolerated by young patients. This article reviews the current literature and discusses the important considerations while managing these patients. Indications for surgery are highlighted, based on our large experience at a tertiary care center.

    The purpose of this study was to examine results with elective surgical correction of enophthalmos. The study was a retrospective assessment in a university-based referral practice. A consecutive sample of 10 patients who developed ocular dystopia following orbital trauma was examined. The main outcome measures were a subjective evaluation by patients and objective measurements of patients' eye position. The intervention was three-dimensional orbital reconstruction with titanium plates. It is concluded that satisfactory correction of enophthalmos and ocular dystopia can be achieved with elective surgery using titanium plates. In addition, intraoperative measurements of eye position in three planes increases the precision of surgery.

    of the diaphragmatic hiatus. METHODS: Fifteen patients were operated with mean age of 46 years using laparoscopic antireflux surgery, with Prolene® or Dacron® mesh reinforcement of the hiatal crura. The patients were operated under general anesthesia by laparoscopy using five trocars. The average time of surgery was 120 minutes. No deaths occurred. The mean postoperative time was 3.5 days. Patients returned to normal activities around the 10th postoperative day. The mean follow-up was five years. In only two patients, in which were used in a Dacron® mesh, and in another Prolene®, there was migration of the mesh to the esophageal lumen causing dysphagia. CONCLUSION: The mesh use in laparoscopic hiatoplasties is good alternative to close the diaphragmatic defect in large hiatal hernias, correction of reflux esophagitis associated with Barrett's esophagus or hiatal hernia/esophagitis recurrence after surgical correction.

    Full Text Available Arbitrariness is an elementary feature of human language, yet seldom an object of comparative inquiry. While arbitrary signals for the same function are relatively frequent between animal populations across taxa, the same signal with arbitrary functions is rare and it remains unknown whether, in parallel with human speech, it may involve call production in animals. To investigate this question, we examined a particular orangutan alarm call - the kiss-squeak - and two variants - hand and leaf kiss-squeaks. In Tuanan (Central Kalimantan, Indonesia, the acoustic frequency of unaided kiss-squeaks is negatively related to body size. The modified variants are correlated with perceived threat and are hypothesized to increase the perceived body size of the sender, as the use of a hand or leaves lowers the kiss-squeak's acoustic frequency. We examined the use of these variants in the same context in another orangutan population of the same sub-species and with partially similar habitat at Cabang Panti (West Kalimantan, Indonesia. Identical analyses of data from this site provided similar results for unaided kiss-squeaks but dissimilar results for hand and leaf kiss-squeaks. Unaided kiss-squeaks at Cabang Panti were emitted as commonly and showed the same relationship to body size as in Tuanan. However, at Cabang Panti, hand kiss-squeaks were extremely rare, while leaf-use neither conveyed larger body size nor was related to perceived threat. These findings indicate functional discontinuity between the two sites and therefore imply functional arbitrariness of leaf kiss-squeaks. These results show for the first time the existence of animal signals involving call production with arbitrary function. Our findings are consistent with previous studies arguing that these orangutan call variants are socially learned and reconcile the role of gestures and calls within evolutionary theories based on common ancestry for speech and music.

    Infective endocarditis is a complex disease to treat. Despite considerable improvements in diagnostic and therapeutic management, mortality in infective endocarditis remains high. Recent data converge in giving a central role to surgery that, within a multidisciplinary approach and with earlier timing, primarily aims to eradicate the infection rather than to treat its acute or chronic complications. In this paper, we sought to review and comment on current available data and last recommendations for the management of patients with infective endocarditis.

    Error correction is an important issue in foreign language acquisition. This paper investigates how students feel about the way in which error correction should take place in a Chinese-as-a foreign-language classroom, based on empirical data of a large scale. The study shows that there is a general consensus that error correction is necessary. In terms of correction strategy, the students preferred a combination of direct and indirect corrections, or a direct only correction. The former choice indicates that students would be happy to take either so long as the correction gets done.Most students didn't mind peer correcting provided it is conducted in a constructive way. More than halfofthe students would feel uncomfortable ifthe same error they make in class is corrected consecutively more than three times. Taking these findings into consideration, we may want to cncourage peer correcting, use a combination of correction strategies (direct only if suitable) and do it in a non-threatening and sensitive way. It is hoped that this study would contribute to the effectiveness of error correction in a Chinese language classroom and it may also have a wider implication on other languages.

    Near infrared (NIR) fluorescence imaging technique can provide precise and real-time information about tumor location during a cancer resection surgery. However, many intraoperative fluorescence imaging systems are based on wearable devices or stand-alone displays, leading to distraction of the surgeons and suboptimal outcome. To overcome these limitations, we design a projective fluorescence imaging system for surgical navigation. The system consists of a LED excitation light source, a monochromatic CCD camera, a host computer, a mini projector and a CMOS camera. A software program is written by C++ to call OpenCV functions for calibrating and correcting fluorescence images captured by the CCD camera upon excitation illumination of the LED source. The images are projected back to the surgical field by the mini projector. Imaging performance of this projective navigation system is characterized in a tumor simulating phantom. Image-guided surgical resection is demonstrated in an ex-vivo chicken tissue model. In all the experiments, the projected images by the projector match well with the locations of fluorescence emission. Our experimental results indicate that the proposed projective navigation system can be a powerful tool for pre-operative surgical planning, intraoperative surgical guidance, and postoperative assessment of surgical outcome. We have integrated the optoelectronic elements into a compact and miniaturized system in preparation for further clinical validation.

    Medial opening wedge high tibial osteotomy (MOW HTO) is now a successful operation with a range of indications, requiring an individualised approach to the choice of intended correction. This manuscript introduces the concept of surgical accuracy as the absolute deviation of the achieved correction from the intended correction, where small values represent greater accuracy. Surgical accuracy is compared in a randomised controlled trial (RCT) between gap measurement and computer navigation groups. This was a prospective RCT conducted over 3 years of 120 consecutive patients with varus malalignment and medial compartment osteoarthritis, who underwent MOW HTO. All procedures were planned with digital software. Patients were randomly assigned into gap measurement or computer navigation groups. Coronal plane alignment was judged using the mechanical tibiofemoral angle (mTFA), before and after surgery. Absolute (positive) values were calculated for surgical accuracy in each individual case. There was no significant difference in the mean intended correction between groups. The achieved mTFA revealed a small under-correction in both groups. This was attributed to a failure to account for saw blade thickness (gap measurement) and over-compensation for weight bearing (computer navigation). Surgical accuracy was 1.7° ± 1.2° (gap measurement) compared to 2.1° ± 1.4° (computer navigation) without statistical significance. The difference in tibial slope increases of 2.7° ± 3.9° (gap measurement) and 2.1° ± 3.9° (computer navigation) had statistical significance (P osteotomy for individual cases. This work is clinically relevant because coronal surgical accuracy was not superior in either group. Therefore, the increased expense and surgical time associated with navigated MOW HTO is not supported, because meticulously conducted gap measurement yields equivalent surgical accuracy. I.

Objective:To summarize the surgical strategy of posterior vertebral column resection (PVCR) to correct severe rigid spinal deformity in our center. Methods:A total of 105 consecutive patients undergoing PVCR for severe rigid deformity from October 2004 to December 2013 were reviewed. There were 47 males and 58 females with an average age of 18.9 years (range, 10-45 years). The flexi-bility of major curve of scoliosis was less than 10%in all patients. The major curve of scoliosis was larger than 150° in 12 patients who were treated with skull-femoral traction in supine position for 4 weeks before surgery. Demographic data, med-ical and surgical histories, perioperative and final follow-up radiographic measurements, and prevalence of perioperative complications were reviewed. Results:The mean operating time was (602±132) min and intraoperative blood loss was (4694±1794) ml. The mean major curve of scoliosis was 108.9° ± 25.5° and 36.6° ± 15.7° before and after PVCR, respectively, and the mean kyphosis was 88.8° ± 31.1° and 29.9° ± 14.1° . In the 12 patients with the curve greater than 150° , the mean major curve of scoliosis was 152.5°±14.3°, 141.8°±16.3°, 93.4°±14.0°, 47.2°±7.2° in standing position before surgery, in supine position before traction, at 4 weeks after traction in supine position and in standing position after surgery, respectively; the kyphosis was 109.3° ± 42.3°, 98.9°±40.0°, 67.3°±22.2°, and 32.2°±9.5°, respectively. The major curve of scoliosis and kyphosis after 4-week trac-tion in supine position were significantly improved when compared with before traction (P<0.05).

    Full Text Available Indications for the surgical treatment of temporomandibular joint (TMJ disorders include: (a a history of recurrent acute dislocation of the condyle,(b osteoarthrosis with pain and serious functional disorder,(c disc displacement without reduction, causing functional disorder. There are several surgical techniques that can be used when the above-mentioned conditions do not respond to conservative treatment. The aim of this study is to present and evaluate the most popular of these techniques by means of five representative cases. These cases are: (1 a case of recurrent dislocation treated by bilateral eminectomy, (2 a case of osteo -arthritis treated by discectomy, (3 a case of disc displacement and perforation corrected by discoplasty,(4 a case similar to the one mentioned before, treated by anchoring the disc to the condyle, and (5 a case of recent anterior disc displacement, also treated by anchoring the disc to the condyle. We present the findings of the long-term postoperative follow-up of these patients. The alternative solutions in each case are then discussed and a comparative evaluation of these solutions is attempted. Finally, we conclude that the aim of the surgical treatment should be to preserve the function of all the normal structures of the joint.

    1998-12-01

    A thorough evaluation of both urethral and penile malformation are mandatory for the choice of the best surgical treatment of patients with hypospadias. The site and the size of the urethral meatus, the presence of a chordee and of a velamentous distal urethra must be carefully assessed. In distal (glandular and coronal) hypospadias, the meatal advancement with glanduloplasty is the treatment of choice. In proximal hypospadias with chordee, the transverse preputial island flap according to the Duckett's technique allows a one-stage hypospadias repair. The awareness of the possible psychologic impact of genital malformations in childhood recommends an early correction of hypospadias, if possible during the first year of life.

    Full Text Available Abstract Congenitally corrected transposition is a rare cardiac malformation characterized by the combination of discordant atrioventricular and ventriculo-arterial connections, usually accompanied by other cardiovascular malformations. Incidence has been reported to be around 1/33,000 live births, accounting for approximately 0.05% of congenital heart malformations. Associated malformations may include interventricular communications, obstructions of the outlet from the morphologically left ventricle, and anomalies of the tricuspid valve. The clinical picture and age of onset depend on the associated malformations, with bradycardia, a single loud second heart sound and a heart murmur being the most common manifestations. In the rare cases where there are no associated malformations, congenitally corrected transposition can lead to progressive atrioventricular valvar regurgitation and failure of the systemic ventricle. The diagnosis can also be made late in life when the patient presents with complete heart block or cardiac failure. The etiology of congenitally corrected transposition is currently unknown, and with an increase in incidence among families with previous cases of congenitally corrected transposition reported. Diagnosis can be made by fetal echocardiography, but is more commonly made postnatally with a combination of clinical signs and echocardiography. The anatomical delineation can be further assessed by magnetic resonance imaging and catheterization. The differential diagnosis is centred on the assessing if the patient is presenting with isolated malformations, or as part of a spectrum. Surgical management consists of repair of the associated malformations, or redirection of the systemic and pulmonary venous return associated with an arterial switch procedure, the so-called double switch approach. Prognosis is defined by the associated malformations, and on the timing and approach to palliative surgical care.

    Full Text Available Problems in the reproductive tract may result in difficulty or inability to copulate. Premature penile deviation is an important cause of impotency in male bovines. The aim of the study was to perform clinical and histological evaluation of the correction of surgically induced penile deviation in bulls by fixing the penile apical ligament in the tunica albuginea using synthetic or biological implants. Twenty-one animals with normal penile conformation were subjected to surgical induction of penile deviation by excision of a fragment from the penile apical ligament and replacement with a chitosan slab or polypropylene mesh. The scarification of the tunica albuginea was assessed as a control. The results showed that the tested or evaluated surgical techniques were ineffective in penile deviation correction, since all the animals failed to reestablish the normal axis of the penis. However, microscopic exam revealed that the chitosan slabs proved to be less irritating to the receptor tissue. Therefore, the proposed surgical techniques using synthetic or biological implants were ineffective for the correction of induced penile deviation in bulls.Los problemas en el tracto reproductivo pueden causar dificultad o incapacidad para copular. La desviación prematura del pene es una causa importante de la impotencia en bovinos machos.

    The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years.

    The adult spastic hand, of varying causes, but dominated by vascular hemiplegia and brain damage, associates motor disorders and problems of tonus. The variety of forms of brain damage explains the wealth and diversity of the symptoms. These symptoms, often the most serious along with cognitive disorders, justify the expression "central neurological hand". Each case is an individual one. The effect on the hands may be unilateral or bilateral with spasticity involving the fingers/thumb/wrist. The clinical evaluation leading to a decision tree must take into account spasticity, retraction and paralysis, for each muscle. When completed by anesthetic motor blocks, spasticity and/or retraction, damage to extrinsic and/or intrinsic muscles of the fingers may be differentiated. This repeated multidisciplinary evaluation makes it possible to distinguish between "non functional hands", "functional hands" and "potentially functional hands". In the first instance, surgery can only improve the esthetic aspect or facilitate nursing. In the second instance, correcting spasticity may improve function. The treatment of spasticity is based on inhibiting spasticity (by injecting botulinum toxin or surgical motor hyponeurotisation) and reinforcing the non-spastic antagonist muscles via tendon transfer or tenodesis. Surgery is indicated to correct muscular retraction and deformities. The functional indications are highly selective and their limited results only allow a "supporting hand" to be constructed at best. The non-functional indications lead to a codified intervention whose results will greatly improve the management of these patients.

    Impairment of the peripheral or central part of the facial nerve causes an ipsilateral peripheral facial nerve paresis. It is quite a common syndrome and affects 20-35 persons per 100,000 per year in Western Europe and the United States. A possible complication of facial palsy is paralytic lagophthalmos with aesthetic and functional impairment for the patient. Beside primary nerve reconstructive procedures plastic-reconstructive procedures play a major role in correcting paralytic lagophthalmos. The eyebrow, upper and lower lids, medial and lateral lid angle as well as the lacrimal system need to be seen as functional units and can be corrected with local surgical procedures. Restoration of eye closure is the most important goal in treating the affected eye. Due to the significant aesthetic limitations and resultant psychological stress for the patient cosmetic aspects must be included in the surgical concept.

    Gout is an inflammatory joint disease associated with deposition of monosodium urate crystals in the bones forming the joints, in periarticular tissues and in other organs. The disease is one of the most frequent causes of disability. This paper presents the case of a 57-year-old male patient treated for generalised gout. A "clinical mask" suggesting another disease was the cause of making the correct diagnosis only six years after the occurrence of the first manifestations. The patient, with high values of inflammatory markers, severe pain and advanced joint destruction, was given an aggressive anti-inflammatory treatment. The unsatisfactory effect of the conservative treatment forced the authors to perform surgical resection of the gouty nodules in the hands. After several operations the function of the hand joints operated on, appearance of the hands and the quality of the patient's life improved significantly.

    2016-06-01

    Surgical intervention is an integral component in the diagnosis and management of mycetoma. Surgical treatment is indicated for small, localised lesions and massive lesions to reduce the mycetoma load and to enable better response to medical therapy. It is also a life-saving procedure in patients with massive disease and sepsis. Surgical options for mycetoma treatment range from a wide local surgical excision to repetitive debridement excisions to amputation of the affected part. Adequate anaesthesia, a bloodless field, wide local excision with adequate safety margins in a suitable surgical facility, and expert surgeons are mandatory to achieve the best surgical outcome. Surgical intervention in mycetoma is associated with considerable morbidity, deformities, and disabilities, particularly in advanced disease.

    Full Text Available Surgical intervention is an integral component in the diagnosis and management of mycetoma. Surgical treatment is indicated for small, localised lesions and massive lesions to reduce the mycetoma load and to enable better response to medical therapy. It is also a life-saving procedure in patients with massive disease and sepsis. Surgical options for mycetoma treatment range from a wide local surgical excision to repetitive debridement excisions to amputation of the affected part. Adequate anaesthesia, a bloodless field, wide local excision with adequate safety margins in a suitable surgical facility, and expert surgeons are mandatory to achieve the best surgical outcome. Surgical intervention in mycetoma is associated with considerable morbidity, deformities, and disabilities, particularly in advanced disease. These complications can be reduced by educating patients to seek medical advice earlier when the lesion is small, localised, and amenable to surgery. There is no evidence for mycetoma hospital cross infection. This communication is based on the authors' experience in managing over 7,200 mycetoma patients treated at the Mycetoma Research Centre, University of Khartoum, Sudan.

  7. Correcting Reflux Laparoscopically

    Full Text Available Most operations in the abdominal cavity and chest can be performed using minimally invasive techniques. As yet it has not been determined which laparoscopic procedures are preferable to the same operations done through conventional laparotomy. However, most surgeons who have completed the learning curves of these procedures believe that most minimally invasive techniques will be scientifically recognized soon. The evolution, validation and justification of advanced laparoscopic surgical methods seem inevitable. Most believe that the trend towards procedures that minimize or eliminate the trauma of surgery while adhering to accepted surgical principles is irreversible. The functional results of laparoscopic antireflux surgery in the seven years since its inception have been virtually identical to the success curves generated with open fundoplication in past years. Furthermore, overall patient outcomes with laparoscopic procedures have been superior to outcomes with the traditional approach. Success is determined by patient selection and operative technique. Patient evaluation should include esophagogastroduodenoscopy, barium swallow, 24 h pH study and esophageal motility study. Gastric emptying also should be evaluated. Patients who have abnormal propulsion in the esophagus should not receive a complete fundoplication (Nissen because it adds a factor of obstruction. Dor or Toupet procedures are adequate alternatives. Prokinetic agents, dilation or pyloroplasty are used for pyloric obstruction ranging from little to more severe. Correcting reflux laparoscopically is more difficult in patients with obesity, peptic strictures, paraesophageal hernias, short esophagus, or a history of previous upper abdominal or antireflux surgery.

    The surgical treatment of complications of diverticulitis remains most challenging. A review of twenty years' experience with one hundred fifteen cases is presented with one proved anastomotic leak and no deaths. Interval primary resection with anastomosis for chronic recurrent disease including colovesical fistula and mesocolic abscess was proved sate with low morbidity. The three-stage procedure for perforated diverticulitis with spreading peritonitis or pericolic abscess was associated with a high rate of complications and morbidity. An aggressive approach with resection without anastomosis in two stages is indicated.

    Reilly, Jaqueline

    2002-09-01

    Surgical wound infection is an important outcome indicator in the postoperative period. A 3-year prospective cohort epidemiological study of 2202 surgical patients from seven surgical wards across two hospitals was carried out using gold standard surveillance methodology. This involved following patients up as inpatients and postdischarge surveillance to 30 days by an independent observer. The results led to the development of a mathematical model for risk of clean, elective surgical wound infection. Risk of surgical wound infection was increased by smoking, higher body mass index, presence of malignancy, haematoma formation, increasing numbers of people in theatre, adherent dressing usage, and higher times to suture removal (P<0.05). The results show that this type of surveillance is an effective way of collecting accurate data on wound infection rates. It was noted that patient care practices affected the surgical wound infection rate and the surveillance was used to facilitate the adoption of evidence-based practice, through recommendations for clean surgery, to reduce the risk from extrinsic risk factors for wound infection. As a result of the implementation of this evidence-based practice there was a significant reduction (P<0.05) in the clean wound infection rate.

  11. Surgical innovation as sui generis surgical research.

    2013-12-01

    Successful innovative 'leaps' in surgical technique have the potential to contribute exponentially to surgical advancement, and thereby to improved health outcomes for patients. Such innovative leaps often occur relatively spontaneously, without substantial forethought, planning, or preparation. This feature of surgical innovation raises special challenges for ensuring sufficient evaluation and regulatory oversight of new interventions that have not been the subject of controlled investigatory exploration and review. It is this feature in particular that makes early-stage surgical innovation especially resistant to classification as 'research', with all of the attendant methodological and ethical obligations--of planning, regulation, monitoring, reporting, and publication--associated with such a classification. This paper proposes conceptual and ethical grounds for a restricted definition according to which innovation in surgical technique is classified as a form of sui generis surgical 'research', where the explicit goal of adopting such a definition is to bring about needed improvements in knowledge transfer and thereby benefit current and future patients.

    2016-09-01

    De-novo scoliosis is most commonly associated with chronic back pain and in 70 % of cases with neurological symptoms of the lower extremities. In recent literature, the occurrence and severity of segmental lateral listhesis has been discussed as being an important prognostic factor of sagittal and frontal deformity progression. In general, operative interventions in patients with de-novo scoliosis are associated with a high rate of complications. Therefore, conservative treatment modalities are recommended at early stages of the disease. If conservative management fails and a sufficient reduction of the patient's symptoms cannot be achieved, depending on the symptoms, a selective decompression, short-segment fusion or long-instrumented reduction and fusion are indicated. Additionally to the patient's symptoms, specific imaging diagnostics are necessary to develop an adequate surgical treatment strategy. Selective decompression without fusion is indicated in patients with a fixed deformity and primarily neurologic pain or deficits. In conditions of a focal pathology as cause of significant low back pain and/or neurologic symptoms at early stages of deformity, a short segment fusion is the treatment of choice. However, short-segment fusion as a less-invasive procedure must not be performed in biplanar unbalanced patients and/or advanced de-novo scoliosis. In advanced degenerative de-novo scoliosis a long-segment reposition and fusion following an alignment correction are needed. Standardized pre-operative planning and perioperative management are highly critical to the post-operative success. All operative treatment strategies in patients with de-novo scoliosis can be successful but they require sophisticated and individual surgical indication.

    Laparoscopic surgery is the standard approach for surgical adrenal gland pathology. However, the open procedure still has its role. Our intention is to report our results and experience using different techniques. A retrospective study of 40 patients was carried out. Demographic and surgical data were analyzed. Thirty two patients had benign pathology and eight had malignant tumors. Laparotomy was performed in 18 patients: seven patients with malignant tumors and 11 with benign pathology. Young's approach was indicated in four patients. Laparoscopic aproach was indicated in 25 patients with seven patients requiring conversion to laparotomy. The conversion rate was 28% In most cases, the laparoscopic approach is the standard technique. Appropriate case selection is of primary importance. Other surgical techniques should be considered if necessary.

  16. Upper Eyelid Filling With or Without Surgical Treatment.

    The upper eyelid of young people is characterized by a proper fullness and projection. Aging eyes show upper eyelid volume loss, symmetric or asymmetric hollowing with too much upper lid showing, dermatochalasis with skin excess. While in the past blepharoplasty surgery was the only approach used to improve eye appearance in the last years, hyaluronic acid (HA) filling of the upper eyelid area has been found very effective in reaching good eye rejuvenation and use of traditional surgical techniques can be limited. A total of 154 patients were enrolled in this study to improve eye appearance. One hundred twenty-eight patients were treated with HA injections in the upper eyelid only, 21 patients underwent surgical treatment followed by HA injections to ensure full correction, and 5 patients underwent blepharoplasty surgery only. The correct approach has been evaluated on the basis of standardized criterion. Twelve-month clinical follow-up was used to evaluate the results and the degree of patient satisfaction was high. The results are very lasting and no modifications after 2 years are common. HA filling is an effective means to rejuvenate the upper eyelid and in several cases it is the only approach able to restore the proper fullness of the upper eyelids. Surgical techniques should be used in the presence of dermatochalasis with excess skin. HA injections in the upper eyelid are easy to perform but it is important to use the correct technique and follow proper indications. This method is a manageable, lasting, and low-cost treatment.

    1980-01-01

    Reference is made to considerable personal experience acquired in the treatment of craniofacial fractures, particularly those affecting the upper third of the face. An account is given of the anatomical and surgical features of the naso-ethmoid-frontal and temporo-orbito-sphenoid areas--now recognised as within the domain of maxillofacial surgery--and their symptomatologies. Particular attention is directed to the question of liquorrhoea and the possibility of ascendent infections of the meninges. Reduction is favoured with respect to the former, since forward and upward repositioning often leads to the regression of ethmoidal liquorrhoea. Exclusion of the frontal sinus is regarded as a "categorical imperative" as far as meningeal infection is concerned, and support is also given for its prevention with antibiotics. A personal preference is expressed for cefuroxim, a new antibiotic with particular potency and marked diffusibility within the cerebrospinal fluid.

  18. Quality of pharmaceutical care in surgical patients.

    Monica de Boer

    Full Text Available BACKGROUND: Surgical patients are at risk for preventable adverse drug events (ADEs during hospitalization. Usually, preventable ADEs are measured as an outcome parameter of quality of pharmaceutical care. However, process measures such as QIs are more efficient to assess the quality of care and provide more information about potential quality improvements. OBJECTIVE: To assess the quality of pharmaceutical care of medication-related processes in surgical wards with quality indicators, in order to detect targets for quality improvements. METHODS: For this observational cohort study, quality indicators were composed, validated, tested, and applied on a surgical cohort. Three surgical wards of an academic hospital in the Netherlands (Academic Medical Centre, Amsterdam participated. Consecutive elective surgical patients with a hospital stay longer than 48 hours were included from April until June 2009. To assess the quality of pharmaceutical care, the set of quality indicators was applied to 252 medical records of surgical patients. RESULTS: Thirty-four quality indicators were composed and tested on acceptability and content- and face-validity. The selected 28 candidate quality indicators were tested for feasibility and 'sensitivity to change'. This resulted in a final set of 27 quality indicators, of which inter-rater agreements were calculated (kappa 0.92 for eligibility, 0.74 for pass-rate. The quality of pharmaceutical care was assessed in 252 surgical patients. Nearly half of the surgical patients passed the quality indicators for pharmaceutical care (overall pass rate 49.8%. Improvements should be predominantly targeted to medication care related processes in surgical patients with gastro-intestinal problems (domain pass rate 29.4%. CONCLUSIONS: This quality indicator set can be used to measure quality of pharmaceutical care and detect targets for quality improvements. With these results medication safety in surgical patients can be enhanced.

    .5% of sinus rhythm was seen detected at discharge and 84.6% at the end of follow-up. In the Control group 87.5% of the patients have atrial fibrillation at discharge and after follow-up atrial fibrillation remained at 56.3% of the patients. There was no difference in the NYHA class between the groups after follow-up (p=0.56 and Control group patients had more complications (p=0.017. CONCLUSION: These results show that both techniques, the Maze and Isolation of Pulmonary Veins, have advantages over simple correction of cardiac lesions when associated to atrial fibrillation.

  20. Surgical approach in patients with hyperparathyroidism in multiple endocrine neoplasia type 1: total versus partial parathyroidectomy

    Directory of Open Access Journals (Sweden)

    Francesco Tonelli

    2012-01-01

    Full Text Available Usually, primary hyperparathyroidism is the first endocrinopathy to be diagnosed in patients with multiple endocrine neoplasia type 1, and is also the most common one. The timing of the surgery and strategy in multiple endocrine neoplasia type 1/hyperparathyroidism are still under debate. The aims of surgery are to: 1 correct hypercalcemia, thus preventing persistent or recurrent hyperparathyroidism; 2 avoid persistent hypoparathyroidism; and 3 facilitate the surgical treatment of possible recurrences. Currently, two types of surgical approach are indicated: 1 subtotal parathyroidectomy with removal of at least 3-3 K glands; and 2 total parathyroidectomy with grafting of autologous parathyroid tissue. Transcervical thymectomy must be performed with both of these procedures. Unsuccessful surgical treatment of hyperparathyroidism is more frequently observed in multiple endocrine neoplasia type 1 than in sporadic hyperparathyroidism. The recurrence rate is strongly influenced by: 1 the lack of a pre-operative multiple endocrine neoplasia type 1 diagnosis; 2 the surgeon's experience; 3 the timing of surgery; 4 the possibility of performing intra-operative confirmation (histologic examination, rapid parathyroid hormone assay of the curative potential of the surgical procedure; and, 5 the surgical strategy. Persistent hyperparathyroidism seems to be more frequent after subtotal parathyroidectomy than after total parathyroidectomy with autologous graft of parathyroid tissue. Conversely, recurrent hyperparathyroidism has a similar frequency in the two surgical strategies. To plan further operations, it is very helpful to know all the available data about previous surgery and to undertake accurate identification of the site of recurrence.

    Conclusion: Since there is no corrective treatment for this type of injuries, the craniomaxillofacial surgeon and other professionals who carry out interventions of this nature need perfect knowledge of the anatomy of the temporal bone and lateral skull base, taking into account the risk of surgical disasters like the one here reported.

  3. The cost effectiveness of vacuum-assisted versus core-needle versus surgical biopsy of breast lesions.

    Fernández-García, P; Marco-Doménech, S F; Lizán-Tudela, L; Ibáñez-Gual, M V; Navarro-Ballester, A; Casanovas-Feliu, E

    To determine the cost effectiveness of breast biopsy by 9G vacuum-assisted guided by vertical stereotaxy or ultrasonography in comparison with breast biopsy by 14G core-needle biopsy and surgical biopsy. We analyzed a total of 997 biopsies (181 vacuum-assisted, 626 core, and 190 surgical biopsies). We calculated the total costs (indirect and direct) of the three types of biopsy. We did not calculate intangible costs. We measured the percentage of correct diagnoses obtained with each technique. To identify the most cost-effective option, we calculated the mean ratios for the three types of biopsies. Total costs were €225.09 for core biopsy, €638.90 for vacuum-assisted biopsy, and €1780.01 for surgical biopsy. The overall percentage of correct diagnoses was 91.81% for core biopsy, 94.03% for vacuum-assisted biopsy, and 100% for surgical biopsy; however, these differences did not reach statistical significance (p=0.3485). For microcalcifications, the percentage of correct diagnoses was 50% for core biopsy and 96.77% for vacuum-assisted biopsy (p<0.0001). For nodules, there were no significant differences among techniques. The mean cost-effectiveness ratio considering all lesions was 2.45 for core biopsy, 6.79 for vacuum-assisted biopsy, and 17.80 for surgical biopsy. Core biopsy was the dominant option for the diagnosis of suspicious breast lesions in general. However, in cases with microcalcifications, the low percentage of correct diagnoses achieved by core biopsy (50%) advises against its use in this context, where vacuum-assisted biopsy would be the technique of choice because it is more cost-effective than surgical biopsy, the other technique indicated for biopsying microcalcifications.

    The planning for surgery in war was revisited in 1937 when Ian Fraser was elected a member of the Surgical Travellers. At their 1938 Surgical Travellers meeting in Vienna, Ian and Eleanor Fraser were evicted from their hotel room by the Nazis. The 1939 meeting in Belfast discussed the organization of surgery and the conduct of Emergency Medical Service Hospitals in the United Kingdom; the vast majority were to be under civilian government and military control. From 1943 lengthy and informative organizational meetings were held at least monthly under the chairmanship of Sir Alexander Hood, KBE, Head of the RAMC. Surgical Consultants, now Major Generals, Brigadiers or Full Colonels in the British and U.S. Armies stationed in the UK, prepared for the invasion of Europe. The allocation of medical, surgical, nursing and auxiliary responsibilities was delineated. Liaison with the RAF and US Army Air Force was close as it was with the proposed leaders, Ulstermen Brooke and Montgomery. Montgomery chose Arthur Porritt as Surgeon in Chief to Supreme Headquarters Allied Expeditionary Force (SHAEF), and Eisenhower, General Albert W. Kenner. Just after D-Day, Porritt met Ian Fraser, who had waded in on Arromanches Beach. The triage and evacuation plans for Allied casualties had been controversial, particularly as regards Landing Ship Tanks (LSTs). The dispute with the Hood-selected surgeons on one side, against medical and surgical deployment of LSTs, and Admiral Ernest King and Winston Churchill on the other, favouring LST use for surgery and evacuation. King and Churchill were correct but total Allied air superiority allowed wide use of many of the Allies' Dakotas; 10,000 DC-3s were eventually in service. Supported by forty Allied combat planes to each Luftwaffe, the dispute about Landing Ship Tank use in about a fortnight became moot. The multifaceted role of the Princess Royal in the Emergency Medical Services of the United Kingdom and her close liaison with the Consultant

    This review article, the second in a series of articles to examine the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) Guidelines for the Use of Parenteral and Enteral Nutrition in Adult and Pediatric Patients, evaluates the evidence related to the use of nutrition support in surgical oncology patients. Cancer patients develop complex nutrition issues. Nutrition support may be indicated in malnourished cancer patients undergoing surgery, depending on individual patient characteristics. As with the first article in this series, this article provides background concerning nutrition issues in cancer patients, as well as discusses the role of nutrition support in the care of surgical cancer patients. The goal of this review is to enrich the discussion contained in the clinical guidelines as they relate to recommendations made for surgical patients, cite the primary literature more completely, and suggest updates to the guideline statements in light of subsequently published studies.

    Ivanov, Marcel; Ciurea, Alexandru Vlad

    2009-01-01

    Neuronavigation and stereotaxy are techniques designed to help neurosurgeons precisely localize different intracerebral pathological processes by using a set of preoperative images (CT, MRI, fMRI, PET, SPECT etc.). The development of computer assisted surgery was possible only after a significant technological progress, especially in the area of informatics and imagistics. The main indications of neuronavigation are represented by the targeting of small and deep intracerebral lesions and choosing the best way to treat them, in order to preserve the neurological function. Stereotaxis also allows lesioning or stimulation of basal ganglia for the treatment of movement disorders. These techniques can bring an important amount of confort both to the patient and to the neurosurgeon. Neuronavigation was introduced in Romania around 2003, in four neurosurgical centers. We present our five-years experience in neuronavigation and describe the main principles and surgical techniques.

    Coelho, Julio C U; Claus, Christiano M P; Campos, Antonio C L; Costa, Marco A R; Blum, Caroline

    2016-07-27

    Umbilical hernia occurs in 20% of the patients with liver cirrhosis complicated with ascites. Due to the enormous intraabdominal pressure secondary to the ascites, umbilical hernia in these patients has a tendency to enlarge rapidly and to complicate. The treatment of umbilical hernia in these patients is a surgical challenge. Ascites control is the mainstay to reduce hernia recurrence and postoperative complications, such as wound infection, evisceration, ascites drainage, and peritonitis. Intermittent paracentesis, temporary peritoneal dialysis catheter or transjugular intrahepatic portosystemic shunt may be necessary to control ascites. Hernia repair is indicated in patients in whom medical treatment is effective in controlling ascites. Patients who have a good perspective to be transplanted within 3-6 mo, herniorrhaphy should be performed during transplantation. Hernia repair with mesh is associated with lower recurrence rate, but with higher surgical site infection when compared to hernia correction with conventional fascial suture. There is no consensus on the best abdominal wall layer in which the mesh should be placed: Onlay, sublay, or underlay. Many studies have demonstrated several advantages of the laparoscopic umbilical herniorrhaphy in cirrhotic patients compared with open surgical treatment.

    1988-07-01

    Over a 6-year period at the University Hospital in London, Ont., 101 patients underwent heart transplantation and 5 heart-lung transplantation. The authors review the general surgical problems identified from the charts of 13 of these patients. In the early postoperative period (within 30 days), laparotomy was required for pancreatitis (one), perforated peptic ulcer (two), cholecystectomy (one), pancreatic cyst (one) and appendicitis (one). In addition, a spontaneous colocutaneous fistula and spontaneous pneumoperitoneum occurred; both were managed conservatively. Later, three patients required cholecystectomy; one underwent a below-knee and a Symes amputation for dry gangrene and one surgical correction of a lymphocele. The incidence of surgical problems (13%) indicates an increased susceptibility in this group of patients. Four of the 13 patients died. Pancreatitis is a well-recognized complication of cardiac surgery; it is frequently associated with a normal or only slightly elevated serum amylase level, making a definitive diagnosis without laparotomy almost impossible. Persistence of abdominal signs should signal the need for exploratory surgery. During the early postoperative period and in the absence of multiorgan failure, immediate operation for an acute abdomen is usually successful. Despite the additional risk, cardiac transplantation does not preclude later surgery, but immunosuppression must be continued and carefully monitored.

    Cervical spinal neurinomas are benign tumors that arise from nerve roots. Based on their location, these tumors can also take the form of a dumbbell-shaped mass. Treatment strategies for these tumors have raised several controversial issues such as appropriate surgical indications and selection of surgical approaches for cervical dumbbell-shaped spinal neurinomas. In this report, we review previous literature and retrospectively analyze cervical spinal neurinoma cases that have been treated at our hospital. Surgical indications and approaches based on tumor location and severity are discussed in detail. Thus, with advances in neuroimaging and neurophysiological monitoring, we conclude that appropriate surgical approaches and intraoperative surgical manipulations should be chosen on a case-by-case basis.

    The extended trochanteric osteotomy is appropriate for a number of surgical indications. It facilitates removal of well-fixed cement mantles with a loose or well-fixed stem and of extensively porous-coated or tapered cementless stems. This exposure is particularly valuable in the presence of varus remodeling of the proximal femur, permitting correction of proximal femoral deformity and reducing the risk of fracture of the greater trochanter. It is also indicated in the removal of a well-fixed cemented stem that is complicated by infection, where it is vital to extract all foreign material for successful eradication of the infection. In addition, when the osteotomy is required for femoral exposure, it enhances acetabular exposure to allow even the most complex reconstruction. Also, as the soft-tissue attachments to the bone fragment are preserved in this approach, abductor muscle tension can be adjusted.

    Full Text Available Objective:To analyze the results from surgical treatment of 69 cases of clubfoot in 43 patients with myelodysplasia according to clinical and radiographic criteria, at our institution between 1984 and 2004.Methods:This was a retrospective study involving analysis of medical files, radiographs and consultations relating to patients who underwent surgical correction of clubfoot. The surgical technique consisted of radical posteromedial and lateral release with or without associated talectomy.Results:The patients' mean age at the time of the surgery was four years and two months, and the mean length of postoperative follow-up was seven years and two months. Satisfactory results were achieved in 73.9% of the feet and unsatisfactory results in 26.1% (p < 0.0001.Conclusion:Residual deformity in the immediate postoperative period was associated with unsatisfactory results. Opening of the Kite (talocalcaneal angle in feet that only underwent posteromedial and lateral release, along with appropriate positioning of the calcaneus in cases that underwent talectomy, was the radiographic parameter that correlated with satisfactory results.

    The parathyroid hormone (PTH) stimulates aldosterone secretion and cell proliferation in human adrenocortical cells; moreover, in rats hyperaldosteronism was associated with hyperparathyroidism. Hence, PTH could drive aldosterone excess in human primary aldosteronism. To test this hypothesis, we recruited 105 consecutive hypertensive patients, of whom 44 had primary aldosteronism due to an aldosterone-producing adenoma (APA) and 61 had primary (essential) hypertension. We measured the plasma levels of (1-84)-PTH, 25(OH)D, 1,25(OH)2D, and serum Ca (total and ionized), inorganic P, Mg, K, and the 24-h urinary excretion of Ca, P, and deoxypyridinoline. In primary aldosteronism patients, these measurements were repeated after adrenalectomy or mineralocorticoid receptor blockade. We also sought for PTH receptor (PTHR-1) mRNA and protein in APA tissue. Compared with primary (essential) hypertension patients, those with primary aldosteronism showed significantly higher plasma PTH (+31%), despite comparable urinary Ca excretion and similarly deficient 25(OH) vitamin D levels. In APA patients, who showed the PTHR-1 transcript and protein in tumor tissue, adrenalectomy normalized PTH levels (from 118 ± 13 to 76 ± 12 ng/l; P = 0.002) and increased ionized Ca(from 1.17 ± 0.04 to 1.22 ± 0.03 mmol/l; P PTHR-1 in APA might contribute to maintaining hyperaldosteronism despite suppression of angiotensin II formation.

  8. Surgical Lasers In Gynecology

    Schellhas, Helmut F.; Barnes, Alfonso E.

    1982-12-01

    Multipurpose surgical CO2 lasers marketed in the USA have been developed to be applicable to a variety of surgical procedures in many surgical fields. They are all suited for endoscopic surgical procedures and can be fitted to all standard surgical microscopes. They all can adjust the focal length of the laser beam to the different standard focal lengths of the surgical microscope which for instance in laryngoscopy is 400 mm and in colposcopy 300 mm. One laser instrument can even change the spot size in a given focal distance which is very advantageous for some microsurgical procedures (Merrimack Laboratories 820). All multipurpose surgical CO2 laser systems provide a multi-articulated surgical arm for free-hand surgery. The surgical arms are cumbersome to use but they are adapted to the surgeons needs with ingenuity. The practicality of the multi-articulated surgical arms depends mostly on the distance of the handpiece from the surgical console which now is also overbridged by the laser tube in most surgical laser system. The spot size of the beam is variable in most handpieces by interchangeable lenses which modify the focal distance of the beam and the power density. Another common feature in all systems is a coaxial He-Ne pilot light which provides a red spot which unfortunately becomes invisible in a bleeding surgical field. Most surgical laser systems have a spacial mode of TEM 00 which is essential for incisional surgery. The continuous mode of beam delivery is used for incisional surgery and also for most endoscopic procedures.

    To evaluate the long-term effectiveness of different therapies applied in the past 30 years, both medical and surgical, and results, with the ultimate aim of determining which are the most appropriate criteria to indicate when and how to perform medical and surgical treatment in these patients. A retrospective randomized study was conducted on 198 patients with primary divergent strabismus first seen in our clinic (IOC) in the last 36 years (1976-2012), with a mean follow-up of 8.38 years. Demographic and clinical characteristics, as well as the various treatments performed, and motor and sensory outcome were collected. They were finally divided into 3 groups of 70, 71 and 56 patients, respectively, according to their first visit, in order to compare the therapies applied. Half (50%) of our patients debuted before 2 years of age (P50=24 months), and 26.3% had optimal binocular vision at the beginning of the study. Medical treatment was used as exclusive therapy in 29.3% of cases (occlusion therapy, applying negative lenses, botulinum toxin), and 70.7% required surgery (61.2% by double retro-insertion of lateral rectus, and 38.8% monolateral retro-resection). There was a recurrence in 26.7% of patients, and 40 re-interventions were performed (70% due to recurrence of divergent strabismus, 12.5% due to surgical over-correction, and 17.5% for other reasons). In the end, 61.1% of patients had perfect binocular vision (TNO=60"), and the proportion was higher in patients who showed proper control of their strabismus at the beginning (P=.003). However, no differences were found in the other variables studied. When the patients were divided into 3 groups (which are demographically comparable), an increased number of patients in Group 3 were found to be treated using negative lenses and botulinum toxin (P<.001 and P=.003). This group was found to have had a higher proportion of bilateral surgery (P=.032), seeking greater immediate postoperative over-correction, thus

    2012-01-01

    Bell's palsy causes lagophthalmos of the involved eyelids. Secondary to the atonicity of the eyelids, xerophthalmia, conjunctivitis and epiphora develops. There are dynamic (muscle transfers) and static (gold weights, tarsorrhaphy) approaches to alleviate these problems. The GOALS of this study are to present a technical note for a surgical method for lengthening the retracted upper eyelid with autogenous temporalis fascia and elevation of the lower eyelid with transplantation of autogenous morselized conchal cartilage graft via standard blepharoplasty incisions. The proposed technique is illustrated in details with an example of a patient with paralytic lagophtalmos. The 4 years follow up of the case operated by this technique shows a stable occlusion of the eyelids with a lowering of the upper eyelid and elevation of the lower eyelid margin. If the paralysis is complete this technique will not accomplish adequate relieve of symptoms. In this cases re-animation of the eyelids with either temporalis muscle transfers or free micro neurovascular muscle transfers are indicated.

  20. Surgical management of chronic pancreatitis

    2007-01-01

    BACKGROUND:Treatment of chronic pancreatitis (CP) is a challenging condition for surgeons. During the last decades, increasing knowledge about pathophysiology of CP, improved results of major pancreatic resections, and integration of sophisticated diagnostic methods in clinical practice have resulted in signiifcant changes in surgery for CP. DATA SOURCES:To detail the indications for CP surgery, the surgical procedures, and outcome, a Pubmed database search was performed. The abstracts of searched articles about surgical management of CP were reviewed. The articles could be identiifed and further scrutinized. Further references were extracted by cross-referencing. RESULTS: Main indications of CP for surgery are intractable pain, suspicion of malignancy, and involvement of adjacent organs. The goal of surgical treatment is to improve the quality of life of patients. The surgical approach to CP should be individualized according to pancreatic anatomy, pain characteristics, baseline exocrine and endocrine function, and medical co-morbidity. The approach usually involves pancreatic duct drainage and resection including longitudinal pancreatojejunostomy, pancreatoduodenectomy (Whipple's procedure), pylorus-preserving pancreatoduodenectomy, distal pancreatectomy, total pancreatectomy, duodenum-preserving pancreatic head resection (Beger's procedure), and local resection of the pancreatic head with longitudinal pancreatojejunostomy (Frey's procedure). Non-pancreatic and endoscopic management of pain has also been advocated. CONCLUSIONS:Surgical procedures provide long-term pain relief, a good postoperative quality of life with preservation of endocrine and exocrine pancreatic function, and are associated with low early and late mortality and morbidity. In addition to available results from randomized controlled trials, new studies are needed to determine which procedure is the most effective for the management of patients with CP.

Postoperatively, the penis was straight in 10 patients and had some degree of downward angulation in 1 boy. The tunica vaginalis free graft seems to be a useful technique for the correction of severe chordee.

    BACKGROUND: Hepatocellular carcinoma (HCC) is a com-plex and heterogeneous malignancy, frequently occurs in the setting of a chronically diseased organ, with multiple con-founding factors making its management challenging. HCC represents one of the leading causes of cancer-related mortal-ity globally with a rising trend of incidence in some of the de-veloped countries, which indicates the need for better surgical and nonsurgical management strategies. DATA SOURCES: PubMed database was searched for relevant articles in English on the issue of HCC management. RESULTS: Surgical resection represents a potentially cura-tive option for appropriate candidates with tumors detected at earlier stages and with well-preserved liver function. The long-term outcome of surgery is impaired by a high rate of recurrence. Surgical approaches are being challenged by local ablative therapies such as radiofrequency ablation and micro-wave ablation in selected patients. Liver transplantation offers potential cure for HCC and also correction of underlying liver disease, and minimizes the risk of recurrence, but is reserved for patients within a set of criteria proposed for a prudent allocation in the shortage of donor organs. Transcatheter locoregional therapies have become the palliative standard allowing local control for intermediate stage patients with noninvasive multinodular or large HCC who are beyond the potentially curative options. The signiifcant survival beneift with the multikinase inhibitor sorafenib for advanced HCC has shifted the direction of research regarding systemic treat-ment toward molecular therapies targeting the disregulated pathways of hepatocarcinogenesis. Potential beneift is sug-gested from simultaneous or sequential multimodal therapies, and optimal combinations are being investigated. Despite the striking progress in preclinical studies of HCC immuno-therapy and gene therapy, extensive clinical trials are required to achieve successful clinical applications

    Full Text Available Surgical instruments are the group of tools used in surgical procedures. They are very expensive and sophisticated. Consequently, a standardized and meticulous care is essential; they should go through the decontamination, cleaning and sterilization process. These instruments are designed in order to provide surgeons with tools that help them to perform a basic surgical procedure; there are multiple variations and the design depends on their function. This paper aims at showing all surgical instruments that can be used in an operating room during surgery and are not generally included in the medical literature.

    Full Text Available Abstract In this review, basic knowledge and recent innovation of surgical treatment for scoliosis will be described. Surgical treatment for scoliosis is indicated, in general, for the curve exceeding 45 or 50 degrees by the Cobb's method on the ground that: 1 Curves larger than 50 degrees progress even after skeletal maturity. 2 Curves of greater magnitude cause loss of pulmonary function, and much larger curves cause respiratory failure. 3 Larger the curve progress, more difficult to treat with surgery. Posterior fusion with instrumentation has been a standard of the surgical treatment for scoliosis. In modern instrumentation systems, more anchors are used to connect the rod and the spine, resulting in better correction and less frequent implant failures. Segmental pedicle screw constructs or hybrid constructs using pedicle screws, hooks, and wires are the trend of today. Anterior instrumentation surgery had been a choice of treatment for the thoracolumbar and lumbar scoliosis because better correction can be obtained with shorter fusion levels. Recently, superiority of anterior surgery for the thoracolumbar and lumbar scoliosis has been lost. Initial enthusiasm for anterior instrumentation for the thoracic curve using video assisted thoracoscopic surgery technique has faded out. Various attempts are being made with use of fusionless surgery. To control growth, epiphysiodesis on the convex side of the deformity with or without instrumentation is a technique to provide gradual progressive correction and to arrest the deterioration of the curves. To avoid fusion for skeletally immature children with spinal cord injury or myelodysplasia, vertebral wedge ostetomies are performed for the treatment of progressive paralytic scoliosis. For right thoracic curve with idiopathic scoliosis, multiple vertebral wedge osteotomies without fusion are performed. To provide correction and maintain it during the growing years while allowing spinal growth for

    2015-10-01

    Anomalous origins of coronary arteries from the pulmonary artery are rare malformations in which the coronary arteries originate from pulmonary artery sinuses or branches. The consequences are variable although, in most cases, these anomalies lead to severe coronary hypoperfusion and ventricular dysfunction. Surgical correction is indicated once the diagnosis is established due to high early mortality associated with the disease. In nearly all cases, the anomalous artery can be excised from its pulmonary origin, mobilized, and reimplanted directly into the ascending aorta using different surgical techniques. In rare circumstances, technical modifications must be used to restore a normal dual coronary perfusion. The emphasis of this article is to provide a collective review of surgical options published in the literature.

    2014-12-01

    Surgical ethics as a specific discipline is relatively new to many. Surgical ethics focuses on the ethical issues that are particularly important to the care of surgical patients. Informed consent for surgical procedures, the level of responsibility that surgeons feel for their patients' outcomes, and the management of surgical innovation are specific issues that are important in surgical ethics and are different from other areas of medicine. The future of surgical progress is dependent on surgical innovation, yet the nature of surgical innovation raises specific concerns that challenge the professionalism of surgeons. These concerns will be considered in the following pages.

    Many surgical techniques have been developed to correct blepharoptosis, including the anterior levator resection or advancement, tarsoaponeurectomy, and Fasanella-Servat Müllerectomy. However, to minimize surgical scarring and reduce the postoperative recovery time, the procedure has been developed from a complete incision to a partial incision, which is appealing to patients. To aid the procedural development, this study describes a surgical technique in which the correction of blepharoptosis and a double eyelid fold operation are performed using a buried suture technique during the same operation. A retrospective review was conducted using the medical records and preoperative and postoperative photography of 121 patients who underwent simultaneous correction of blepharoptosis and had a double eyelid fold created between October 2010 and July 2011. All of the patients had mild (1-2 mm) or moderate (3-4 mm) bilateral blepharoptosis and excellent or good levator function (>8 mm). The average preoperative marginal reflex distance (MRD1) measured 1.174 (0.3) mm. No intraoperative complications occurred. The average postoperative MRD1 measured 3.968 (0.2) mm. There was statistical significance improvement between preoperative MRD1 and postoperative MRD1 (Pexposure keratopathy were noted. Blepharoptosis correction using the buried suture technique is an effective technique for young patients experiencing mild to moderate blepharoptosis who want to have the double eyelid fold operation using the buried suture technique.

    This paper presents an approach to spelling correction in agglutinative languages that is based on two-level morphology and a dynamic programming based search algorithm. Spelling correction in agglutinative languages is significantly different than in languages like English. The concept of a word in such languages is much wider that the entries found in a dictionary, owing to {}~productive word formation by derivational and inflectional affixations. After an overview of certain issues and relevant mathematical preliminaries, we formally present the problem and our solution. We then present results from our experiments with spelling correction in Turkish, a Ural--Altaic agglutinative language. Our results indicate that we can find the intended correct word in 95\\% of the cases and offer it as the first candidate in 74\\% of the cases, when the edit distance is 1.

    Surgical fusion of the subtalar joint is a procedure indicated to alleviate pain of subtalar origin, such as in post-traumatic osteoarthritis, adult-acquired flatfoot deformity, and other disorders. Open subtalar arthrodesis has been performed with predictable results, but concerns exist regarding injury to proprioception and local vascularity due to wide surgical dissection. Minimally invasive techniques try to improve results by avoiding these issues but have a reputation for being technically demanding. We describe the surgical technique for arthroscopic subtalar arthrodesis, which has proved to be a safe and reliable technique in our experience, with consistent improvements in American Orthopaedic Foot & Ankle Society scores.

    Objective To analysis anterior corneal surface shape changes in pediatric myopic overnight or-thokeratology. Methods Retrospective observational case series were observed. Tomey TMS -4 was used to receive corneal topographic data before and after overnight orthokeratology lens wear. Seventy-five pediatric myopic patients (150 eyes, age range: 9~17 years) were included. The myopia was -4.23±1.82 (range:-8.75~-0.75) D, the astigmatism was -0.3±0.47 (range: -2~0) D, and spherical equivalent refraction was -4.34±1.88 (range: -9.13~-0.75) D. Topog-raphy data was collected and analyzed when uncorrected visual acuity (UCVA) was 1.0. Results After normative or-thokeratology lens correction, UCVAs of one hundred and fifty eyes reached 1.0, and no severe complications were ob-served. The topography parameters showed that mean Ks:41.19±1.73D,Kf:39.67±1.67D,AveK:40.43±1.61D, PVA:-0.01±0.09~0.11±0.08 (LogMAR), Es:-0.14±0.47,Em:-0.39±0.34,SRI:0.49±0.33,SAI:0.84±0.60, and were significantly different from no lens wear. No significant change was observed in Cyl (1.48±0.96D) before and after lens wear. The fluctuation range above parameters’ means were ks:0.82±0.83 (0~3.88) D,Kf:0.69±0.75 (0.01~4.54) D,Avek:0.71±0.75 (0.01~3.51) D,Cyl:0.45±0.48 (0.01~2.70) D,Es:0.27±0.31 (0~1.14),Em:0.18±0.24 (0~1.51),Sri:0.19±0.20 (0~1.02),Sai:0.40±0.55 (0~3.65) . Conclusions Improved visual acuity after overnight wear of orthokeratology lens can be attributed to changes in anterior corneal curvature and E value. Corneal regular astigmatism remained unchanged, but corneal PVA reduced and corneal irregularity increased. Improved UCVA can be maintained within a certain fluctuation of topography parameters.%目的:分析青少年近视眼经角膜塑形镜矫正后角膜前表面的变化。方法回顾性分析青少年近视患者共75人150眼,年龄9~17岁,屈光状态:-4.23±1.82(-8.75~-0.75) Ds/-0.3±0.47(-2~0)Dc,等效球镜度数:-4.34±1.88(-9

    Premature closure of metopic suture is a relatively uncommon form of craniosyostosis with an estimated incidence of 0,3 per 1000 live births, comprising about 7% of surgical craniosynostosis referred to craniofacial centers. A broad phenotypical spectrum spreads from minor metopic ridges to severe trigonocephaly with pterional indentation supraorbital bar retrusion, temporal and parietal compensating bossings and hypotelorism. Most of the cases arise spontaneously although autosomal dominant inheritance has been described and association with cromosomal abnormalities and different syndromes has been widely reported. Surgical correction has been attempted with good cosmetic results using several variations of the standard frontoorbitary advance. However there is still a number of questions to be solved in relation to this entity, mainly on its pathogenesis, but also on its development, natural history and treatment. Direct surgical approach to associated hypotelorism is a matter of argument when considering the reestablishment of normal interorbitary distances. We have conducted a retrospective analysis of our serie consisting of twenty-eight cases of trigonocephalies. Surgical correction of hypotelorism was attempted in eleven cases while the resting seven children remained "not treated". The objective was to review the functional outcome and cosmetic results comparing the different techniques applied to the frontal bone and to observe evolution of the hypoteleorbitism after the treatment with or without osteotomies and grafting of the nasoethmoidal area.

    Many dermatologic diseases, including vitiligo and other pigmentary disorders, vascular malformations, acne, and disfiguring scars from surgery or trauma, can be distressing to pediatric patients and can cause psychological alterations such as depression, loss of self-esteem, deterioration of quality of life, emotional distress, and, in some cases, body dysmorphic disorder. Corrective camouflage can help cover cutaneous unaesthetic disorders using a variety of water-resistant and light to very opaque products that provide effective and natural coverage. These products also can serve as concealers during medical treatment or after surgical procedures before healing is complete. Between May 2001 and July 2003. corrective camouflage was used on 15 children and adolescents (age range, 7-16 years; mean age, 14 years). The majority of patients were girls. Six patients had acne vulgaris; 4 had vitiligo; 2 had Becker nevus; and 1 each had striae distensae, allergic contact dermatitis. and postsurgical scarring. Parents of all patients were satisfied with the cosmetic cover results. We consider corrective makeup to be a well-received and valid adjunctive therapy for use during traditional long-term treatment and as a therapeutic alternative in patients in whom conventional therapy is ineffective.

    Dreyfus, G

    1998-11-01

    Cardiac transplantation is the treatment of reference for refractory cardiac failure but the limited number of donors, the complications inherent to transplantation and the relative and absolute contra-indications has made it necessary to find alternative surgical solutions. The detection of myocardial viability by Thallium scintigraphy, Dobutamine echocardiography and/or position emission tomography in coronary disease, allows identification of zones which are capable of recovering contractile function after revascularisation. The authors report the results of a series of 91 operated patients with a 10 year follow-up having a 72% 5 year actuarial survival and improved ejection fraction. The other alternative which may improve symptoms and prognosis in patients with severe ischaemic heart disease with left ventricular dysfunction is apical remodelling or Dor's procedure. The results of a haemodynamic study at 1 year of 171 patients clearly show a functional improvement and an increase of the ejection fraction. The advantage of this method is that it can be used in patients with dyskinetic and akinetic plaques resulting from antero-septo-apical infarction. Finally, even if mitral regurgitation is relatively uncommon in chronic ischaemic heart disease, a simple procedure (annuloplasty) is often sufficient to correct the mitral regurgitation and reduce the afterload of a failing ventricle. On the other hand, in dilated cardiomyopathy, two new options have been developed; one, suggested by Steven Bolling, proposes simple mitral annuloplasty whatever the underlying cause (primary or ischaemic cardiomyopathy) with symptomatic improvement and better haemodynamics in terms of increased cardiac output and oxygen consumption on exercise and an actuarial survival much higher than that of cardiac transplantation at one and at two years. The most recent innovation is the Batista procedure which is a method of ventricular reduction associated with correction of mitral

    2015-01-01

    The encounter between a patient and her surgeon is unique for several reasons. The surgeon inflicts pain upon a patient for the patient's own good. An operative intervention is irreducibly personal, such that the decisions about and performance of operations are inseparable from the idiosyncrasies of the individual surgeon. Furthermore, there is a chasm of knowledge between the patient and surgeon that is difficult to cross. Hence, training in the discipline of surgery includes the inculcation of certain virtues and practices to safeguard against abuses of this relationship and to make sure that the best interests of the patient are prioritized. The stories in this issue are evidence that in contemporary practice this is not quite enough, as surgeons reflect on instances they felt were ethically challenging. Common themes include the difficulty in communicating surgical uncertainty, patient-surgeon relationships, ethical issues in surgical training, and the impact of the technological imperative on caring for dying patients.

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    Waardenburg syndrome is characterized by lateral displacement of the medial canthi and lacrimal puncta, a broad nasal root, poliosis, heterochromia iridis, hyperplasia of the medial portion of the eyebrows, and congenital sensorineural deafness. As a group, these symptoms rarely occur in one individual, so care must be taken not to confuse an isolated condition with the syndrome. Of all the manifestations, the authors believe the lateral displacement of the medial canthi is the key factor in making a diagnosis. Sensorineural deafness is the most handicapping symptom. Surgical treatment is indicated for the correction of dystopia canthorum. We present a technique based on a double Z-plasty and nasal transfixion, plus attachment of the medial canthal tendons according to the techniques of Callahan and Mustardé.

    Diverticular bleeding is the most common cause of acute severe lower gastrointestinal bleeding. Diagnostic and therapeutic approaches have not been standardized. Development of an evidence-based management algorithm. A systematic search of the literature (PubMed 1998-2013) was carried out and a review with consideration of current guidelines is given. The lifetime risk of clinically relevant bleeding is estimated to be 5 % in persons with colonic diverticula. Patients with clinically suspected diverticular hemorrhage should be admitted to hospital. Diverticular bleeding will cease spontaneously in around 70-90 % of the cases. In patients with severe lower gastrointestinal tract bleeding, defined as instability of the circulation, persistent bleeding after 24 h, drop of the hemoglobin level to ≥ 2 g/dl or the necessity for transfusion, endoscopy of the upper and lower gastrointestinal tract within the first 12-24 h is recommended. In patients with active diverticular bleeding or signs of recent hemorrhage (e.g. visible vessel or adherent clot) endoscopic therapy is strongly recommended because it significantly decreases the rate of early and late rebleeding. Angiography with superselective embolization is a therapeutic option in patients where endoscopy failed. Surgery should be considered in patients with ongoing bleeding and failure of interventional treatment and in patients who suffered from recurrent severe diverticular bleeding. Diverticulosis coli remains the most common cause of lower gastrointestinal bleeding. Colonoscopy is recommended as first-line diagnostic and therapeutic approach. In the vast majority of patients diverticular hemorrhage can be readily managed either conventionally or by interventional therapy.

    Full Text Available ABSTRACTPurpose:To report and compare the surgical, visual, and anatomical outcomes following treatment of dislocated intraocular lenses (IOLs.Methods:The medical records of 28 eyes of 28 patients were evaluated. Age, gender, pre-and postoperative best-corrected visual acuity (BCVA, surgical methods, and complications were recorded.Results:Pre-and postoperative BCVA ranged from counting fingers to 20/32 and from counting fingers to 20/25, respectively. Late-onset dislocations were the most frequently observed complication. The most frequent surgical method was IOL repositioning in 15 of 28 patients, followed by IOL exchange in 11 patients, and IOL removal in 2 patients. Only 1 patient required surgical re-intervention with IOL capture.Conclusions:Visual acuity improved following the use of either IOL repositioning or IOL exchange. No superiority of one method over the other was observed. In the present retrospective case series, management of dislocated IOLs with repositioning or exchange of the primary implant conferred comparable surgical and visual outcomes.

    2012-06-01

    Full Text Available Abstract Background Studies have highlighted the effects the use of the WHO Surgical Safety Checklist can have on lowering mortality and surgical complications. Implementation of the checklist is not easy and several barriers have been identified. Few studies have addressed personnel’s acceptance and attitudes toward the WHO Surgical Safety Checklist. Determining personnel’s acceptance might reflect their intention to use the checklist while their awareness and knowledge of the checklist might assess the effectiveness of the training process. Methods Through an anonymous self- responded questionnaire, general characteristics of the respondents (age, gender, profession and years spent studying or working at the hospital, knowledge of the WHO Surgical Safety Checklist (awareness of existence, knowledge of objectives, knowledge of correct use, acceptance of the checklist and its implementation (including personal belief of benefits of using the checklist, current use, teamwork and safety climate appreciation were determined. Results Of the 147 surgical personnel who answered the questionnaire, 93.8% were aware of the existence of the WHO Surgical Safety Checklist and 88.8% of them reported knowing its objectives. More nurses than other personnel knew the checklist had to be used before the induction of anesthesia, skin incision, and before the patient leaves the operating room. Most personnel thought using the WHO Surgical Safety Checklist is beneficial and that its implementation was a good decision. Between 73.7% and 100% of nurses in public and private hospitals, respectively, reported the checklist had been used either always or almost always in the general elective surgeries they had participated in during the current year. Conclusions Despite high acceptance of the checklist among personnel, gaps in knowledge about when the checklist should be used still exist. This can jeopardize effective implementation and correct use of the checklist

    Reuther, J

    2000-05-01

    The article reviews the history of orthognathic surgery from the middle of the last century up to the present. Initially, mandibular osteotomies were only performed in cases of severe malformations. But during the last century a precise and standardized procedure for correction of the mandible was established. Multiple modifications allowed control of small fragments, functionally stable osteosynthesis, and finally a precise positioning of the condyle. In 1955 Obwegeser and Trauner introduced the sagittal split osteotomy by an intraoral approach. It was the final breakthrough for orthognathic surgery as a standard treatment for corrections of the mandible. Surgery of the maxilla dates back to the nineteenth century. B. von Langenbeck from Berlin is said to have performed the first Le Fort I osteotomy in 1859. After minor changes, Wassmund corrected a posttraumatic malocclusion by a Le Fort I osteotomy in 1927. But it was Axhausen who risked the total mobilization of the maxilla in 1934. By additional modifications and further refinements, Obwegeser paved the way for this approach to become a standard procedure in maxillofacial surgery. Tessier mobilized the whole midface by a Le Fort III osteotomy and showed new perspectives in the correction of severe malformations of the facial bones, creating the basis of modern craniofacial surgery. While the last 150 years were distinguished by the creation and standardization of surgical methods, the present focus lies on precise treatment planning and the consideration of functional aspects of the whole stomatognathic system. To date, 3D visualization by CT scans, stereolithographic models, and computer-aided treatment planning and simulation allow surgery of complex cases and accurate predictions of soft tissue changes.

    Full Text Available Mucormycosis is rare in clinical practice. Most infections are acquired by inhalation; other portals of entry are traumatic implantation and ingestion in immunocompromised host. Mucormycosis is life threatening infection in immunocompromised host with variable moratlity ranging from 15 -81% depending upon site of infection. General treatment principles include early diagnosis, correction of underlying immunosuppression and metabolic disturbances, adequate surgical debridement along with amphotericin therapy. We describe surgical site mucormycosis extended to involve large bowel in elderly diabetic patient.

    Full Text Available This article provides an overview of surgical procedures performed with questionable or excessively radical indications, such as the lung denervation as a treatment of asthma, or the porto-systemic shunting for Type 1 diabetes mellitus. An immediate effect of an invasive procedure including a surgical operation can be influenced by different non-specific factors including a placebo effect. There is an opinion that surgery is associated with a placebo-effect, which can be stronger in case of a more invasive procedure. Reported moderate efficiency of the procedures discussed here could have been caused by placebo effect and/or inexact evaluation. These days, the improvement of Russian economy has enabled the acquisition of modern equipment and supported increasing levels of medical research. Under these circumstances, the purpose of this review is to help to correct the historical problems of surgery in Russia and to remind that, when performing surgical or other invasive procedures, the risk-to-benefit ratio should be minimized.

    Potential dangers associated with smoke generated during electrosurgery have been described. However, the use of smoke management in dermatology is unknown. There is no objective data showing the amount or the composition of the smoke generated in dermatologic surgeries. To assess the use of smoke management in dermatologic surgery and provide data on the amount and chemical composition of surgical smoke. A total of 997 surveys were sent to dermatologic surgeons across the United States to assess the use of smoke management. Amounts and concentrations of particulates and chemical composition were measured during electrosurgery using a particulate meter and the Environmental Protection Agency-standardized gas chromatography-mass spectrometry analysis. Thirty-two percent of the surgeons responded to the survey, and 77% of the respondents indicated no use of smoke management at all. Only approximately 10% of surgeons reported consistent use of smoke management. Active electrosurgery produced significant amounts of particulates. In addition, surgical smoke contained high concentrations of known carcinogens, such as benzene, butadiene, and acetonitrile. Surgical smoke contains toxic compounds and particulates. Most dermatologic surgeons do not use smoke management within their practices. Raising the awareness of the potential risks can help increase the use of smoke management.

    Retained surgical sponges (RSS) are an avoidable complication following surgical operations. RSS can elicit either an early exudative-type reaction or a late aseptic fibrous tissue reaction. They may remain asymptomatic for long time; when present, symptomatology varies substantially and includes septic complications (abscess formation, peritonitis) or fibrous reaction resulting in adhesion formation or fistulation into adjacent hollow organs or externally. Plain radiograph may be useful for the diagnosis; however, computed tomography is the method of choice to establish correct diagnosis preoperatively. Removal of RSS is always indicated to prevent further complications. This is usually accomplished by open surgery; rarely, endoscopic or laparoscopic removal may be successful. Prevention is of key importance to avoid not only morbidity and even mortality but also medicolegal consequences. Preventive measures include careful counting, use of sponges marked with a radiopaque marker, avoidance of use of small sponges during abdominal procedures, careful examination of the abdomen by the operating surgeon before closure, radiograph in the operating theater (either routinely or selectively), and recently, usage of barcode and radiofrequency identification technology.

    Lipodystrophy is a pathological condition characterized by the focal or general absence of adipose tissue. Surgeons reset the patient's surface contours using injectable materials to recreate a normal physical appearance. However, due to difficulties in preoperative planning and intraoperative assessment, about 15% of the surgical procedures involved are reinterventions to improve volume or symmetry. This increases the need for an available, efficient tool capable of providing the surgeon with a good estimation of the volumes to be injected before the intervention proper begins. This work describes a virtual reality-based application for the surgical planning of facial lipodystrophy correction (FLIC). The tool uses points selected interactively by the surgeon to compute a curve that delimits the surface area to be operated on. It then automatically computes an estimated natural reconstructed surface and the quantity of volume that needs to be implanted during the intervention. Experiments have been carried out in which the filling volumes estimated using FLIC and ZBrush software were compared with the real volumes injected by the surgeon. ICCs higher than 0.97 indicate that there were no significant differences between the respective measurements, thus validating the tool proposed in this paper.

    Opening wedge high tibial osteotomy (OWHTO) is a surgical procedure that aims to correct the weight-bearing axis of the knee, moving the loads laterally from the medial compartment. Conventional indications for OWHTO are medial compartment osteoarthritis and varus malalignment of the knee; recently OWHTO has been used successfully in the treatment of double and triple varus. OWHTO, in contrast to closing wedge high tibial osteotomy, does not require fibular osteotomy or peroneal nerve dissection, or lead to disruption of the proximal tibiofibular joint and bone stock loss. For these reasons, interest in this procedure has grown in recent years. The aim of this study is to review the literature on OWHTO, considering indications and prognostic factors (body mass index, grade of osteoarthritis, instability, range of movement and age), outcomes at mid-term follow-up, and limits of the procedure (slope modifications, patellar height changes and difficulties in conversion to a total knee arthroplasty).

    1998-01-01

    Surgery is needed in every second patient with pancolitis. Historically four surgical options have been developed: conventional ileostomy, ileorectostomy, continent ileostomy (Kock's pouch) and ileo-anal pouch. However, in emergent or unclear situations subtotal colectomy, ileostomy and preservation of the rectum is the most suitable operation. After recovery and in elective indications proctectomy and proctocolectomy establish the general surgical standard. Today, in most cases ileo-pouch-anal anastomosis is performed instead of creation of an ileostomy. Both lowered frequency of defecation and acceptable continence contribute to a better quality of life. However, functional disturbances are not uncommon and result in most cases from complications of the demanding technique. Definitive cure of the colitis is in interference with the risk of pouchitis in about 30%. The cumulative probability to loose the pouch may rise to 15-20% in the long-term course. Thus, ileorectostomy may be considered as a first step of surgical treatment, since pelvic nerve damage is excluded, function is much better and persistent proctitis can be treated topically. The attractively is that ileo-anal pouch can be performed later on, when decreasing function and increasing risk of malignant change will eventually require proctectomy. A Kock-pouch is seldom considered, especially in patients with ileostomy wishing sure fecal control. But the continent reservoir becomes more and more interesting again since it can be reconstructed from a failed ileo-anal pouch without loss of bowel. Conventional ileostomy should be reserved for patients not suitable for reconstructive methods or those who consider pough operations risk. However, it is the safest procedure with absolute cure of disease. The optimal choice of method considers medical and surgical aspects as well as patients conception and desire.

    We present quasar bolometric corrections using the [O III] λ 5007 narrow emission line luminosity based on the detailed spectral energy distributions of 53 bright quasars at low to moderate redshift (0.0345 diversity, introduces scatter into the L_{[O III]}-Liso relationship. We found that the {[O III]} bolometric correction can be significantly improved by adding a term including the equivalent width ratio R_{Fe II} ≡ EW_{{Fe II}}/EW_{Hβ }, which is an EV1 indicator. Inclusion of R_{Fe II} in predicting Liso is significant at nearly the 3σ level and reduces the scatter and systematic offset of the luminosity residuals. Typically, {[O III]} bolometric corrections are adopted for Type 2 sources where the quasar continuum is not observed and in these cases, R_{Fe II} cannot be measured. We searched for an alternative measure of EV1 that could be measured in the optical spectra of Type 2 sources but were unable to identify one. Thus, the main contribution of this work is to present an improved {[O III]} bolometric correction based on measured bolometric luminosities and highlight the EV1 dependence of the correction in Type 1 sources.

    AIM:To evaluate the diagnostic accuracy(DA) in acute surgical patients admitted to a District General Hospital.METHODS: The case notes of all acute surgical patients admitted under the surgical team for a period of two weeks were reviewed for the data pertaining to the admission diagnoses, relevant investigations and final diagnoses confirmed by either surgery or various other diagnostic modalities. The diagnostic pathway was recorded from the source of referral [general practitioner(GP), A and E, in-patient] to the correct final diagnosis by the surgical team. RESULTS: Forty-one patients(23 males) with acute surgical admissions during two weeks of study period were evaluated. The mean age of study group was 61.05 ± 23.24 years. There were 111 patient-doctor encounters. Final correct diagnosis was achieved in 85.4% patients. The DA was 46%, 44%, 50%, 33%,61%, 61%, and 75% by GP, A and E, in-patient referral, surgical foundation year-1, surgical senior house officer(SHO), surgical registrar, and surgical consultant respectively. The percentage of clinical consensus diagnosis was 12%. Surgery was performed in 48.8% of patients. Sixty-seven percent of GP-referred patients, 31% of A and E-referred, and 25% of the in-patient referrals underwent surgery. Surgical SHO made the most contributions to the primary diagnostic pathway.CONCLUSION: Approximately 85% of acute surgical patients can be diagnosed accurately along the diagnostic pathway. Patients referred by a GP are more likely to require surgery as compared to other referral sources. Surgical consultant was more likely to make correct surgical diagnosis, however it is the surgical SHO that contributes the most correct diagnoses along the diagnostic pathway.

  14. The surgical management of spasticity.

    2002-05-01

    Neurosurgery is only considered for severe spasticity following the failure of noninvasive management (adequate medical and physical therapy). The patients are carefully selected, based on rigorous multidisciplinary clinical assessment. In this we evaluate the contribution of the spasticity to the disability and any residual voluntary motor function. The goals for each patient are: (a) improvement of function and autonomy; (b) control of pain; and (c) prevention of orthopaedic disorders. To achieve these objectives, the surgical procedure must be selective and reduce the excessive hypertonia without suppressing useful muscle tone and limb functions. The surgical procedures are: (1) Classical neuro-ablative techniques (peripheral neurotomies, dorsal rhizotomies) and their modern modifications using microsurgery and intra-operative neural stimulation (dorsal root entry zone: DREZotomy). These techniques are destructive and irreversible, with the reduced muscle tone reflecting the nerve topography. It is mainly indicated when patients have localized spasticity without useful mobility. (2) Conservative techniques based on a neurophysiological control mechanism. These procedures are totally reversible. The methods involve chronic neurostimulation of the spinal cord or the cerebellum. There are only a few patients for whom this is indicated. Conversely, chronic intrathecal administration of baclofen, using an implantable pump, is well established in the treatment of diffuse spasticity of spinal origin. From reports in the literature, we critically review the respective indications in terms of function, clinical progression and the topographic extent of the spasticity.

  15. Modified basal osteotomy combined with osteogenic distraction (Hemi-Wing distraction) for correction of facial asymmetry: A new technique

    Muñoz, Ruben; Diaz, Alvaro; Golaszewski, Jose

    2014-01-01

    Complete restoration of facial asymmetry is always difficult to achieve. Facial asymmetry due to growth disturbances of the jaws almost requires orthognathic surgical correction, followed, in many cases, by soft tissue corrections. Mandibular hypoplasia is the earliest skeletal manifestation of Hemifacial microsomy and the clinical defect becomes worse with the time, due to asymmetric growth and secondary midface deformity accompanying. Despite correction of the occlusal plane, facial asymmetry can persist if the mandibular body differs in height. We designed a new technique for skeletal correction of the mandibular basal plane combined with orthognatic surgery that avoided the disadvantages and limitations of other techniques. A 20-year-old male patient with facial asymmetry due to Hemifacial microsomy Type I also requires preoperative orthodontic treatment to align and level their teeth. He showed a 2mm midline shift to the left in combination with a cross bite of the left side. We decide to do a vertical enlargement of the mandibular left border by mandibular Hemiwing osteotomy and unilateral split ramus osteotomy for dental lines alignment with 8 mm of advancement of the hemi - wing genioplasty. Modificated basal osteotomy combined with osteogenic distraction works better than the classic total basal osteotomy with autologous bone graft, if used for the correct indications. We advocate this technique for its efficacy, simplicity, and safety. This technique can be apply for correction of vertical and transverse discrepancies of the mandibular border and combined with sagittal ramus osteotomies for correction of asymmetrical dental lines and oclusal plane.

    The aim of the study was to compare the incidence of sella turcica bridging and sella turcica dimensions in 150 Caucasian subjects who had combined surgical-orthodontic correction of their malocclusion with a randomly selected group of 150 Caucasian subjects who were treated contemporaneously by orthodontic means only. Pretreatment lateral cephalometric radiographs were scanned and analyzed. A sella turcica bridge was identified as a continuous band of bony tissue extending from the anterior cranial fossa to the posterior cranial fossa. The dimensions of the sella turcica were measured. In the group treated by combined surgical-orthodontic means, the incidence of bridging was 16.7%, whereas it was 7.3% in the orthodontics-only group (P = .012). Significant increases in the mean surface area (P = .02) and mean perimeter of the sella turcica (P = .01) were found for the combined surgical-orthodontic group compared with the orthodontics-only group. The mean interclinoid distance was significantly smaller in the surgical-orthodontic group (P = .02). These findings appear to indicate the greater likelihood of sella turcica bridging and abnormal sella turcica dimensions in subjects treated by combined surgical-orthodontic means rather than by orthodontics only.

    A retrospective case series. To review the surgical results for midcervical kyphosis in 3 cases with Larsen syndrome, and to discuss the choice of surgical treatments. Cervical kyphosis is the most hazardous and serious manifestation of Larsen syndrome due to the risk of life-threatening paralysis, and thus usually requires surgical treatment. However, little information has been reported concerning surgical treatments for this challenging condition. Three patients with Larsen syndrome were surgically treated for midcervical kyphosis at our institution. An infant with mild cervical kyphosis was successfully treated with posterior arthrodesis using a halo immobilization, and anterior vertebral growth with a mature posterior fusion mass resulted in spontaneous correction of the kyphosis. In the remaining 2 infants with myelopathic symptoms due to severe and structural kyphosis, anterior decompression and fusion via a lateral approach followed by posterior fusion with segmental spinal instrumentation and halo immobilization resulted in improved neurologic symptoms and solid fusion. Posterior spinal fusion is only indicated for patients with mild and flexible cervical kyphosis, and anterior decompression and circumferential arthrodesis is required for patients with severe kyphotic deformity, who usually develop myelopathic symptoms. Anterior surgery for such a small patient with severe kyphosis involves much higher risk of spinal cord injury during decompression maneuvers and difficulty in stabilization of the reconstructed cervical spine. Therefore, all patients with Larsen syndrome should be screened with radiographs at the first visit to detect cervical kyphosis early so that posterior alone fusion is possible.

  19. Automatic orientation correction for radiographs

    In picture archiving and communications systems (PACS), images need to be displayed in standardized ways for radiologists' interpretations. However, for most radiographs acquired by computed radiography (CR), digital radiography (DR), or digitized films, the image orientation is undetermined because of the variation of examination conditions and patient situations. To address this problem, an automatic orientation correction method is presented. It first detects the most indicative region for orientation in a radiograph, and then extracts a set of low-level visual features sensitive to rotation from the region. Based on these features, a trained classifier based on a support vector machine is employed to recognize the correct orientation of the radiograph and reorient it to a desired position. A large-scale experiment has been conducted on more than 12,000 radiographs covering a large variety of body parts and projections to validate the method. The overall performance is quite promising, with the success rate of orientation correction reaching 95.2%.

    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    2014-01-01

    Condylar hyperplasia of the mandible is a clinical condition of over-development and growth because of excessive cellular growth of one condylar part of the mandible leading to facial asymmetry, mandibular deviation and enlargement of condyle. The elongation of the condylar neck in turn leads to malocclusion and articular dysfunction. In the past the interceptive and corrective procedures of growth and deformity in condylar hyperplasia were either condylectomy or high condylotomy. However, the deformity ceases after growth is completed. Therefore, other surgical procedures have to be undertaken to correct the manifested deformity of condylar hyperplasia. Further it has to be stressed that no single procedure can completely correct the deformity. So in addition to condylectomy, other orthognathic surgical procedures both on body and ramus and also on maxilla can be undertaken to correct the canting of occlusion. Two rare cases of unilateral hyperplasia encountered in our hospital are presented which required different lines of treatment.

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    The ART and SIRT image reconstruction techniques are introduced and a correction factor which provides high resolution images is presented. The techniques were tested using synthetic measurements. In order to examine the manner in which each reconstruction progresses, the Euclidean distance for the reconstructions were plotted, versus iteration number. Results indicate that ART produces better reconstructed profiles than the SIRT (using identical correction factors).

  11. [Surgical treatment of the rheumatoid hand].

    In rheumatoid arthritis, involvement of the hand is serious, frequent and occurs early. It reaches synovial sheets, articular or tendinous, and causes painful and invalidating deformities. Our experience, based on 537 operations of the hand, indicates that reconstructive surgery can be practised at all levels. For the wrist, inferior radio ulnar arthrodesis strengthens the articulation and eradicates pain when performed in the early stage. Segmentar resection of ulnar diaphysis ensures the conservation of "prono- supination". In the case of destruction or luxation of the wrist, a choice has to be made between prosthesis and arthrodesis. We tend to prefer the latter which confers a strong, painless and definitive articulation. Ulnar deviation of metacarpo-phalangeal articulations of long fingers can be corrected by ligamentar or tendinous plasties. But the results are not always durable and they cannot be used when the articulations are destroyed. In that case prostheses have to be implanted. Swanson's silastic implants enable to straighten the fingers and to suppress pain but ensure a limited mobility. Likewise, interphalangeal deviations generally call for implants or arthrodeses. Trapezo-metacarpal or phalangeo-metacarpal deformities of the thumb are stabilised by arthrodeses, ensuring a strong and painless prehension. In conclusion, reconstructive surgery allows many possibilities but its results are often incomplete. It is therefore advisable to perform synovectomy as early as possible before the occurrence of deformities. Surgical synovectomy competes with isotopic, chemical or corticoid synoviosthesis. But at tendinous level, synovectomy alone should be used, since it gives excellent results. Even though rehabilitation after synovectomies is not always easy, we hope that it will prevent the occurrence of articular or tendinous destruction for many years.

  12. Social indicators.

    The notions of social indicators and social accounting, expressed by analogy with the national economic accounts, generated excitement in the 1960's, and the interest continues to grow if we may judge from governmental activity and the publication of programmatic and research papers. But the concepts which focused much of the early enthusiasm gave exaggerated promise of policy applications and provided an unproductive basis for research. The essential theoretical prerequisites for developing a system of social accounts-defining the variables and the interrelationships among them-are missing. It is now realized that evaluation research, particularly experimentation, must be relied on for evaluation of government programs. Through the development and analysis of descriptive time series and the modeling of social processes, we will be able to describe the state of the society and its dynamics and thus improve immensely our ability to state problems in a productive fashion, obtain clues as to promising lines of endeavor, and ask good questions. But these activities cannot measure program effectiveness. Finally, we must be skeptical about definitions of the social indicators enterprise which confine it to social engineering efforts. The issue is not whether social indicators are useful for policy but, rather, how this usefulness comes about. The interest in social indicators has stimulated a revival of interest in quantitative, comparative, social analysis (60), in the analysis of social change, in conceptual and measurement work on such topics as prejudice, crime, and learning, and in the development of models of social processes. The fruit of these efforts will be more directly a contribution to the policy-maker's cognition than to his decisions. Decision emerges from a mosaic of inputs, including valuational and political, as well as technical components. The work we have described deals with only one type of input; it is a contribution to the intellectual mapping

  15. Indicators of coal metamorphism

    Energy Technology Data Exchange (ETDEWEB)

    Proskuryakov, A.E.

    1982-06-01

    Important in determining metamorphism of coal is the reliability of indicators of coalification. Both the reflection of vitrinite and emission of volatile matter have been used for this purpose. To determine which indicator more accurately characterizes metamorphism of coal, their conformity to the following demands was established: 1. uniformity in direction of change of parameters with degree of metamorphism; 2. independence of the indicator of the genetic characteristics of coal (petrographic composition, reduction and oxidation of coal); 3. sensitivity of indicator. Both indicators conform to the first requirement. Emission of volatile substance decreases and reflective capacity of vitrinite increases uniformly with degree of metamorphism. However, the reflectivity of vitrinite is not influenced by petrographic composition of coals and is less dependent on the oxidation and reduction of coal than emission of volatile matter. It is also a more sensitive indicator distinguishing more degrees of metamorphism than emission of volatile matter. Reflectivity of vitrinite is a more reliable indicator of metamorphism than emission of volatile matter. However, in many laboratories this indicator is not measured with sufficient accuracy. To correct this, measuring equipment must be standardized.

    The aim of the present case report is to describe the orthodontic-surgical treatment of a 17-year-and-9-month-old female patient with a Class III malocclusion, poor facial esthetics, and mandibular and chin protrusion. She had significant anteroposterior and transverse discrepancies, a concave profile, and strained lip closure. Intraorally, she had a negative overjet of 5 mm and an overbite of 5 mm. The treatment objectives were to correct the malocclusion, and facial esthetic and also return the correct function. The surgical procedures included a Le Fort I osteotomy for expansion, advancement, impaction, and rotation of the maxilla to correct the occlusal plane inclination. There was 2 mm of impaction of the anterior portion of the maxilla and 5 mm of extrusion in the posterior region. A bilateral sagittal split osteotomy was performed in order to allow counterclockwise rotation of the mandible and anterior projection of the chin, accompanying the maxillary occlusal plane. Rigid internal fixation was used without any intermaxillary fixation. It was concluded that these procedures were very effective in producing a pleasing facial esthetic result, showing stability 7 years posttreatment. PMID:25431691

    We give an induction-free axiom system for diophantine correct open induction. We relate the problem of whether a finitely generated ring of Puiseux polynomials is diophantine correct to a problem about the value-distribution of a tuple of semialgebraic functions with integer arguments. We use this result, and a theorem of Bergelson and Leibman on generalized polynomials, to identify a class of diophantine correct subrings of the field of descending Puiseux series with real coefficients.

    For more than 110 years hands of surgeons have been treated before a surgical procedure in order to reduce the bacterial density. The kind and duration of treatment, however, has changed significantly over time. Recent scientific evidence suggests a few changes with the aim to optimize both the efficacy and the dermal tolerance. Aim of this article is the presentation and discussion of new insights in surgical hand disinfection. A hand wash should be performed before the first disinfection of a day, ideally at least 10 min before the beginning of the disinfection as it has been shown that a 1 min hand wash significantly increases skin hydration for up to 10 min. The application time may be as short as 1.5 min depending on the type of hand rub. Hands and forearms should be kept wet with the hand rub for the recommended application time in any case. A specific rub-in procedure according to EN 12791 has been found to be suitable in order to avoid untreated skin areas. The alcohol-based hand rub should have a proven excellent dermal tolerance in order to ensure appropriate compliance. Considering these elements in clinical practice can have a significant impact to optimize the high quality of surgical hand disinfection for prevention of surgical site infections.

    Just like simulators are a standard in aviation and aerospace sciences, we expect for surgical simulators to soon become a standard in medical applications. These will correctly instruct future doctors in surgical techniques without there being a need for hands on patient instruction. Using virtual reality by digitally transposing surgical procedures changes surgery in are volutionary manner by offering possibilities for implementing new, much more efficient, learning methods, by allowing the practice of new surgical techniques and by improving surgeon abilities and skills. Perfecting haptic devices has opened the door to a series of opportunities in the fields of research,industry, nuclear science and medicine. Concepts purely theoretical at first, such as telerobotics, telepresence or telerepresentation,have become a practical reality as calculus techniques, telecommunications and haptic devices evolved,virtual reality taking a new leap. In the field of surgery barrier sand controversies still remain, regarding implementation and generalization of surgical virtual simulators. These obstacles remain connected to the high costs of this yet fully sufficiently developed technology, especially in the domain of haptic devices.

  5. Disc degeneration: current surgical options

    Full Text Available Chronic low back pain attributed to lumbar disc degeneration poses a serious challenge to physicians. Surgery may be indicated in selected cases following failure of appropriate conservative treatment. For decades, the only surgical option has been spinal fusion, but its results have been inconsistent. Some prospective trials show superiority over usual conservative measures while others fail to demonstrate its advantages. In an effort to improve results of fusion and to decrease the incidence of adjacent segment degeneration, total disc replacement techniques have been introduced and studied extensively. Short-term results have shown superiority over some fusion techniques. Mid-term results however tend to show that this approach yields results equivalent to those of spinal fusion. Nucleus replacement has gained some popularity initially, but evidence on its efficacy is scarce. Dynamic stabilisation, a technique involving less rigid implants than in spinal fusion and performed without the need for bone grafting, represents another surgical option. Evidence again is lacking on its superiority over other surgical strategies and conservative measures. Insertion of interspinous devices posteriorly, aiming at redistributing loads and relieving pain, has been used as an adjunct to disc removal surgery for disc herniation. To date however, there is no clear evidence on their efficacy. Minimally invasive intradiscal thermocoagulation techniques have also been tried, but evidence of their effectiveness is questioned. Surgery using novel biological solutions may be the future of discogenic pain treatment. Collaboration between clinicians and basic scientists in this multidisciplinary field will undoubtedly shape the future of treating symptomatic disc degeneration.

    Surgical extraction of as much tumour mass as possible is considered the first step of treatment in acromegaly in many centers. In this article the potential benefits, disadvantages and limitations of operative acromegaly treatment are reviewed. Pertinent literature was selected to provide a review covering current indications, techniques and results of operations for acromegaly. The rapid reduction of tumour volume is an asset of surgery. To date, in almost all patients, minimally invasive, transsphenoidal microscopic or endoscopic approaches are employed. Whether a curative approach is feasible or a debulking procedure is planned, can be anticipated on the basis of preoperative magnetic resonance imaging. The radicality of adenoma resection essentially depends on localization, size and invasive character of the tumour. The normalization rates of growth hormone and IGF-1 secretion, respectively, depend on tumour-related factors such as size, extension, the presence or absence of invasion and the magnitude of IGF-1 and growth hormone oversecretion. However, also surgeon-related factors such as experience and patient load of the centers have been shown to strongly affect surgical results and the rate of complications. As compared to most medical treatments, surgery is relatively cheap since the costs occur only once and not repeatedly. There are several new technical gadgets which aid in the surgical procedure: navigation and variants of intraoperative imaging. For the mentioned reasons, current algorithms of acromegaly management suggest an initial operation, unless the patients are unfit for surgery, refuse an operation or only an unsatisfactory resection is anticipated. A few suggestions are made when a re-operation could be considered.

    Polydactyly of the foot is a relatively common condition. Approximately 15% of cases are preaxial, with one third of these cases involving duplication of the metatarsal [metatarsal type preaxial polydactyly (MTPP)].Surgical reconstruction of polydactyly is indicated to improve shoe tolerance. Reconstruction of MTPP has traditionally involved resection of the hypoplastic lateral ray in addition to soft tissue reconstruction to correct hallux varus. Poor postoperative results have frequently been reported, primarily due to residual hallux varus. We present a novel surgical technique for the treatment of children with MTPP presenting with a cosmetic lateral hallux, involving an amalgamating osteotomy that permits retention of the stable medial metatarsotarsal joint while avoiding the complication of residual hallux varus. This was a retrospective case series describing the surgical technique of an amalgamating osteotomy in the treatment of patients with MTPP and a cosmetic lateral hallux. The surgical technique involves corresponding metatarsal osteotomies of the medial and lateral halluces, with amalgamation of the metatarsals and ablation of the residual medial hallux, without the need for extensive soft tissue reconstruction. Clinical and radiologic outcomes were evaluated at a minimum of 2 years postoperatively in 2 patients who underwent this technique. Two children, 1 female and 1 male, underwent an amalgamating osteotomy at the age of 31 and 18 months, respectively. At latest follow-up, 7.3 and 2.8 years after osteotomy, respectively, both patients displayed an excellent functional result according to the Phelps and Grogan clinical outcome scale. Plain radiographs in both cases demonstrated a well-aligned first ray with no growth abnormality and no hallux varus. We have presented a novel surgical technique for the reconstruction of MTPP presenting with a cosmetic lateral hallux, involving an amalgamating osteotomy without extensive soft tissue reconstruction

    Full Text Available Purpose: The purpose was to estimate the prevalence of blindness due to cataract, assess visual outcomes of cataract surgery, and determine the cataract surgical coverage rate and barriers to uptake of services among individuals aged 50 years or older in Plateau State, Nigeria. Materials and Methods: A population-based, cross-sectional survey of 4200 adults 50 years or older was performed. Multistage stratified random sampling, with probability proportional to size was used to select a representative sample. The Rapid Assessment of Cataract Surgical Services protocol was used. Statistical significance was indicated by (P 0.05. The prevalence of monocular blindness due to cataract was 5.9% (95% CI: 5.2-6.6%. The cataract surgical coverage for subjects with visual acuity (VA less 3/60 was 53.8% in the entire cohort; 60.5% for males and 48% for females (χ2 = 2.49, P > 0.05. The couching coverage for subjects who were blind was 12%. A total of 180 eyes underwent surgical intervention (surgery or couching for cataract, of which, 48 (26.7% eyes underwent couching. The prevalence of bilateral (pseudo aphakia was 1.5%, (95% CI: 1.2-1.9% and 2.7% (95% CI: 2.2-3.2% for unilateral (pseudo aphakia. Visual outcomes of the 180 eyes that underwent surgical intervention were good (VA ≥ 6/18 in 46 (25.6% eyes and poor (VA < 6/60 in 105 (58.3% eyes. Uncorrected aphakia was the most common cause of poor outcome (65.1%. Most subjects who underwent cataract surgery were not using spectacles 74 (71.2%. Cost and lack of awareness were the main barriers to uptake of cataract surgery services. Conclusion: Couching remains a significant challenge in Nigeria. The outcomes of cataract surgery are poor with the lack of aphakic correction being the main cause of the poor outcomes.

    Objective With increased incidence of prostate cancer and an increased number of patients undergoing radical prostatectomy in China,it will be necessary to elaborate the diagnosis,clinical significance and treatment of patients whose tumors have positive surgical margins following radical prostatectomy.Data sources Positive surgical margin,prostate cancer and radical prostatectomy were used as subject words and the medical literature in recent decades was searched using the PubMed database and the results are summarized.Study selection Using positive surgical margin,prostate cancer and radical prostatectomy as subject words the PubMed medical database produced 275 papers of pertinent literature.By further screening 28 papers were selected and they represent relatively large-scale clinical randomized and controlled clinical trials.Results A pertinent literature of 275 papers was identified and 28 papers on large clinical studies were obtained.Analysis of results indicated that the positive rate of surgical margin after radical prostatectomy is 20%-40%,and although most patients with positive surgical margins are stable for a considerable period,the data available now suggested that the presence of a positive surgical margin will have an impact on the patient's prognosis.The risk factors of positive surgical margin include preoperative prostate specific antigen level,Gleason's score and pelvic lymph node metastasis.The most common site with positive surgical margin is in apical areas of the prostate;therefore surgical technique is also a factor resulting in positive surgical margins.From data available now it appears that as long as the surgical technique is skilled,different surgical modes do not affect the rate of surgical margin.Adjuvant radiotherapy is mainly used to treat patients with positive surgical margin after radical prostatectomy,but combination with androgen deprivation therapy may increase the curative effect.Conclusion The current data indicated that

    Full Text Available Cervical spondylotic myelopathy (CSM is emerging as the most common cause of spinal cord dysfunction in the elderly worldwide. In the past decade, our understanding of the biomechanics of the spine has improved along with advances in spinal instrumentation and this has led to significant changes in the surgical management of CSM. This review will discuss the indications, advantages and limitations of different operative approaches as well as the complications and prognosis of surgery for cervical spondylotic myelopathy. Choice of surgical approach for CSM should be based on the clinical and radiological characteristics of the individual patient and not on the preferences of the surgeon.

    Objective A surgical team has performed total correction of Tetralogy of Fallot ( TF) consecutively in 115 patients without surgical death. This paper presents an investigation of how to improve the surgical outcome. Methods This group included 115 children, the ages of these children at operation were from 9 months to 13 years(4.6 ± 2.7 years), 47.8% of whom were younger than 3 years old. Associated anomalies included atresia of main pulmonary artery or unilateral pulmonary artery in 4 cases, atrial septal defect ( ASD ) and patent ductus arteriosus ( PDA ) in 11 cases. All patients have undergone total correction. Ventricular septal defects were closed with Dacron patches. Autologous-pericardial patches were used to enlarge the right ventricular outflow tract and pulmonary arteries. 102 cases (89%) needed transannular patches. Results There was no surgical death and the patients have been followed up for 2 months to 4 years. One child died of cardiac arrhythmia 3 months after operation. The remaining patients recovered well. Conclusion The key points in improving the surgical outcome in TF patients lie in the improvement of surgical technique, total elimination of obstruction of right ventricular outflow tract and distal pulmonary arteries. Attention should be paid to the cardiopulmonary bypass and the postoperative care should also be emphasized.

    Full Text Available The purpose - to study the morphofunctional changes of upper extremities in patients with brachymetacarpia. Material and methods. The results of the examination and surgical treatment by distraction osteosynthesis of six patients (10 hands, shortening of the 18-metacarpal bones with brachymetacarpia are presented. Results. All patients noted dissatisfaction with the cosmetic state of hands and tiredness during physical activities with the hand. IV ray was shortened in 50%, V ray - in 33% of cases and III ray - in 17%. Limitation of active flexion was noted in all patients, an average flexion was 58.9 ± 7,1°. After treatment flexion increased an average on 20.5 ° (22.7%. Complications were obtained in two patients on three hands. Conclusions. Brachymetacarpia is a rare disease, the etiology of which is still unknown and requires further study. In all cases of brachymetacarpia there is a restriction of active flexion of the MCP joint of the affected ray and the indications for treatment are caused not only by a cosmetic defect, but also functional impairment. Surgical treatment of brachymetacarpia by distraction osteosynthesis gives predictably good results. Complications during the treatment of brachymetacarpia are rare and mostly related to the appearance of contractures, in order to prevent which in the postoperative period should be used preventive conservative therapy.
