Hérnia perineal após disjunçao da sínfise púbica: apresentação de caso e técnica para correção

Traunatic perineal hernia remains a rare clinical entity despite an overall increase in blunt trauma. Because of the incidence of other associated injuries, the mortality is high. Most of the perineal defects are repaired during the orthopaedics surgery to reconstitute the pelvis and few patients develop a true perineal hernia without pelvic instability. A 80-year-old woman was involved in a running over accident with disjunction of pubic symphysis, dislocation of sacrum-iliac junction and fracture of pubis and ischium. The patient was submitted to an orthopaedic surgery and latter development an perineal hernia through the genitalia. The diagnosis could be established with physical examination alone. Conventional radiology, computadorized tomography, and ultrasound should also be done to progran the surgery. The repair approach was performed using a marlex mesh, fixed in the pelvic bones, Cooper ligament, and the abdominal wall. The mesh was stood in a retro- peritoneal position, rebuilding the pelvic floor without reconstruction the pelvic bones. We conclude that this is an efficient approach to repair of traumatic postoperative perineal hernia, mainly in patients with high operative risk, when the osseous repair is not necessary.

Hérnia traumática da parede abdominal

A rare case of blunt traumatic abdominal hernia is presented in which jejunal loops herniated through the abdominal wall. The patient had a serious motor vehicle accident seven years ago, while wearing the seat belt. He developed a traumatic hernia in the anterior lateral abdominal wall, which was operated, and relapsed after some months. The patient was reoperated and we observed the unattachment of the anterior lateral abdominal musculature from the ilium crest. After the hernial sac treatment, the defect was solved with the use of a polypropylene mesh. The postoperative evolution was good and four months later there were no signs of recurrence. Traumatic abdominal hernia remains a rare clinical entity, despite the increase in blunt abdominal trauma. Traumatic abdominal wall hernia falls into two general categories: small lower quadrant abdominal defects, typically the result of blunt trauma with bicycle handlebars, and larger abdominal wall defects related to motor vehicle accidents. The diagnosis may be often established by the physical examination alone. Conventional radiology and computerized tomography usefulness have been proved. In the vast majority of cases, early repair is recommended. The appropriate treatment is the reduction of the herniated bowel into the abdomen, the debridment of nonviable tissues, and a primary tension free closure of the detect.

Carcinoma Adenoescamoso primário de fígado

Adenosquamous carcinoma of the liver is a rare type of hepatic tumor first described in 1975. It is characterized by both glandular and squamous compounds. We describe a case of adenosquamous carcinoma of the liver. It was discovered in a 42-yr-old female with a 2-month history of vomiting, weight loss (7 kg). A left hepatic lobectomy disclosed an 11 x 9 x 7,5 cm tumor located at I, II, III, IV segments. This tumor is rare entity and is a variant of cholangiocarcinoma whose etiology and prognostic are not well known.

Corporate Social Responsibility in the Oil and Gas Industry: Environmental Management Systems as a Source of Sustainable Development

The environmental aspect of corporate social responsibility (CSR) expressed through the process of the EMS implementation in the oil and gas companies is identified as the main subject of this research. In the theoretical part, the basic attention is paid to justification of a link between CSR and environmental management. The achievement of sustainable competitive advantage as a result of environmental capital growth and inclusion of the socially responsible activities in the corporate strategy is another issue that is of special significance here. Besides, two basic forms of environmental management systems (environmental decision support systems and environmental information management systems) are explored and their role in effective stakeholder interaction is tackled. The most crucial benefits of EMS are also analyzed to underline its importance as a source of sustainable development. Further research is based on the survey of 51 sampled oil and gas companies (both publicly owned and state owned ones) originated from different countries all over the world and providing reports on sustainability issues in the open access. To analyze their approach to sustainable development, a specifically designed evaluation matrix with 37 indicators developed in accordance with the General Reporting Initiative (GRI) guidelines for non-financial reporting was prepared. Additionally, the quality of environmental information disclosure was measured on the basis of a quality – quantity matrix. According to results of research, oil and gas companies prefer implementing reactive measures to the costly and knowledge-intensive proactive techniques for elimination of the negative environmental impacts. Besides, it was identified that the environmental performance disclosure is mostly rather limited, so that the quality of non-financial reporting can be judged as quite insufficient. In spite of the fact that most of the oil and gas companies in the sample claim the EMS to be embedded currently in their structure, they often do not provide any details for the process of their implementation. As a potential for the further development of EMS, author mentions possible integration of their different forms in a single entity, extension of existing structure on the basis of consolidation of the structural and strategic precautions as well as development of a unified certification standard instead of several ones that exist today in order to enhance control on the EMS implementation.

Ascite quilosa traumática

Chylous ascites is a rare clinical entity. In infancy it is less commom still. The etiology of most of them is usually congenital or idiopathic; trauma is a less frequent cause. It has been implicated in about 10% of all cases 1-5. There have been less than one hundred cases published in the English literature, including 12 in children. We report a pediatric case of chylous ascites as a result of blunt abdominal trauma managed by ligation of the lymphatic leak.

Marcadores tumorais no câncer colorretal

Colorectal cancer is a clinical entity of a persistent relevance in clinical practice and its early diagnosis is a determinant factor to obtain better therapeutic results. Tumor markers are helpful means for a better approach to individuals with such neoplasm. In the present review, the authors analyze the phases in which surgical-clinical treatment markers must be used: diagnosis, determination of tumor stage, establishment of prognosis and detection of recurrence. Current and future markers and the consensus on their use are discussed. Causal factors for errors in diagnosis with markers and perspectives of use are also presented.

Aneurisma roto de artéria esplênica: flagrante tomográfico de sangramento

The splenic artery aneurysm is a rare entity and its rupture is the most feared complication. The tomographic computed scan is a potential tool in the diagnosis, and can be used to patients with a suspicion of intra-abdominal bleeding, after adequate resuscitation. A case of a 68-year old male, hypertense patient, with a ruptured splenic artery aneurysm is reported. The diagnosis and treatment were given successfully by the abdominal computed tomographic scan and conventional surgery. The tomographic computed scan can be useful to the diagnosis of ruptured splenic artery aneurism, after the hemodynamic stabilization.

Hematoma espontâneo do músculo reto abdominal

Spontaneous hematoma of the rectus sheath is a rare entity, which may be confused with the surgical causes of acute abdomen. We present a well succeeded conservative therapy in a woman in the 7th decade of life.

Torção do grande omento

We present two cases of greater omental torsion, a rare condition of acute abdominal pain, emphasizing the clinical manifestations and imaging findings, which can lead us to the difficult preoperative diagnosis of this entity.

Atualização em GIST

Gastrointestinal stromal tumor (GIST) has been recently the subject of considerable clinical and experimental interest. This focus is based on insights gained during the past years concerning its identification as a distinct clinical entity and the advances in knowledge about the diagnosis and management. Historically, surgery has been considered the most effective treatment in spite of its limitations. Others therapeutic approaches have been tryng without success, until the introduction of imatinib. This drug provided hopeful results in the treatment of this neoplasia. The idea that imatinib could improve surgical outcome have led to some clinical trials with the hope that this association (imatinib & surgery) could achieve good results.

Duplicação uretral em homem adulto

Urethral duplication is a rare congenital anomaly. The clinical presentation and treatment varies because of the different anatomical patterns of this abnormality. We report a case of this entity in the adult male patient. The clinical, radiological and endoscopic findings, as well as the treatment are discussed.

Pseudotumor pancreático

The decrease in morbidity and mortality of pancreaticoduodenectomy in reference centers has increased the incidence of benign histopathologic diagnosis in cases where a pre-operative diagnosis of pancreatic ductal carcinoma was expected (9,2%). Recent reports have shown that autoimune pancreatitis, an entity that can lead to a pathologic diagnosis of sclerosing lymphoplasmatic pancreatitis has been the cause of about 2,5% of wrong preoperative diagnosis. Clinical and image definitive diagnosis is still uncertain on those borderline cases. An increase in IgG4 has been reported as frequent in patients with autoimune pancreatitis which can respond to steroid treatment. In doubtful cases, four diagnosis can be expected: 1. Pancreatic ductal carcinoma; 2. Chronic alcoholic pancreatitis; 3. "Chronic pancreatitis secondary to choledocal lithiasis"; 4. Sclerosing lymphoplasmatic pancreatitis. Modern medical literature sugests that evaluation of IgG4 in doubtful cases of pancreatic tumor (pseudotumor of the pancreas) could avoid unnecessary pancreaticoduodenectomies in the future.

Câncer colo-retal hereditário

The colorectal cancer has become a world public health problem as a consequence of the great number of new cases which have been diagnosed each year and the existence of some conditions related to the disease's natural history that can be identified and the cancer prevented. Knowing the fact that 20% out of all colorectal cancers develops as part of a hereditary cancer syndrome, it is crucial that the physician (not only the surgeon) be updated with this entity, being able to recognize, and mainly, implement screening programs to identify family members at risk of developing cancer and to allow the intervention to prevent the occurrence of the adenoma-carcinoma sequence.

Rabdomioma da cabeça e pescoço

Rhabdomyoma is a rare soft tissue tumor and account for 1 to 2 % of skeletal muscle tumors. Rhabdomyomas are uncommon with less than one hundred cases reported. Head and neck rhabdomyomas have their origin in the third and fourth branchial clefts skeletal muscle. Describe the clinical, histopathological and radiological aspects of a recurrent adult mouth floor rhabdomyoma and the differential diagnosis for this uncommon entity. Two years after surgical resection, of a fifty-four years old male patient, with mouth floor rhabdomyoma, he started to complain of submucosal lesion at the oropharynx right lateral wall. The CT scan has shown extension to the parapharyngeal space and recurrent rhabdomyoma hypothesis has been done. The patient underwent a new surgical resection and the histopathological examination confirmed a recurrent adult rhabdomyoma.

The Finnish Paper Workers' Union at a crossroads: Labor union representativeness in a changing environment, 1980-2008

This thesis consists of four articles and an introductory section. The main research questions in all the articles refer to the changes in the representativeness of the Finnish Paper Workers' Union. Representativeness stands for the entire entity of external, internal, legal and reputational factors that enable the labor union to represent its members and achieve its goals. This concept is based on an extensive reading of quantitative and qualitative industrial relations literature, which includes works based on Marxist labor-capital relations (such as Hyman's industrial relations studies), and more recent union density studies as well as gender- and ethnic diversity-based 'union revitalization' studies. Müller-Jentsch's German studies of industrial relations have been of particular importance as well as Streeck's industrial unionism and technology studies. The concept of representativeness is an attempt to combine the insights of these diverse strands of literature and bring the scientific discussion of labor unions back to the core of a union's function: representing its members. As such, it can be seen as a theoretical innovation. The concept helps to acknowledge both the heterogeneity of the membership and the totality of a labor union organization. The concept of representativeness aims to move beyond notions of 'power'. External representativeness can be expressed through the position of the labor union in the industrial relations system and the economy. Internal representativeness focuses on the aspects of labor unions that relate to the function of the union as an association with members, such as internal democracy. Legal representativeness lies in the formal legal position of the union – its rights and instruments. This includes collective bargaining legislation, co-decision rules and industrial conflict legislation. Reputational representativeness is related to how the union is seen by other actors and the general public, and can be approximated using data on strike activity. All these aspects of representativeness are path-dependent, and show the results of previous struggles over issues. The concept of representativeness goes beyond notions of labor union power and symbolizes an attempt to bring back the focus of industrial relations studies to the union's basic function of representing its members. The first article shows in detail the industrial conflict of the Finnish paper industry in 2005. The intended focus was the issue of gender in the negotiations over a new collective agreement, but the focal point of the industrial conflict was the issue of outsourcing and how this should be organized. Also, the issue of continuous shifts as an issue of working time was very important. The drawn-out conflict can be seen as a struggle over principles, and under pressure the labor union had to concede ground on the aforementioned issues. The article concludes that in this specific conflict, the union represented its' female members to a lesser extent, because the other issues took such priority. Furthermore, because of the substantive concessions. the union lost some of its internal representativeness, and the stubbornness of the union may have even harmed the reputation of the union. This article also includes an early version of the representativeness framework, through which this conflict is analyzed. The second article discusses wage developments, union density and collective bargaining within the context of representativeness. It is shown that the union has been able to secure substantial benefits for its members, regardless of declining employment. Collective agreements have often been based on centralized incomes policies, but the paper sector has not always joined these. Attention is furthermore paid to the changing competition of the General Assembly, with a surprisingly strong position of the Left Alliance still. In an attempt to replicate analysis of union density measures, an analysis of sectoral union density shows that similar factors as in aggregate data influence this measure, though – due to methodological issues – the results may not be robust. On this issue, it can be said that the method of analysis for aggregate union density is not suitable for sectoral union density analysis. The increasingly conflict-ridden industrial relations predicted have not actually materialized. The article concludes by asking whether the aim of ever-increasing wages is a sustainable one in the light of the pressures of globalization, though wage costs are a relatively small part of total costs. The third article discusses the history and use of outsourcing in the Finnish paper industry. It is shown using Hyman's framework of constituencies that over time, the perspective of the union changed from 'members of the Paper Workers' Union' to a more specific view of who is a core member of the union. Within the context of the industrial unionism that the union claims to practice, this is an important change. The article shows that the union more and more caters for a core group, while auxiliary personnel is less important to the union's identity and constituencies, which means that the union's internal representativeness has decreased. Maintenance workers are an exception; the union and employers have developed a rotating system that increases the efficient allocation of these employees. The core reason of the exceptional status of maintenance personnel is their high level of non-transferable skills. In the end it is debatable whether the compromise on outsourcing solves the challenges facing the industry. The fourth article shows diverging discourses within the union with regard to union-employer partnership for competitiveness improvements and instruments of local union representatives. In the collective agreement of 2008, the provision regulating wage effects of significant changes in the organization or content of work was thoroughly changed, though this mainly reflected decisions by the Labor Court on the pre-2008 version of the provision. This change laid bare the deep rift between the Social Democratic and Left Alliance (ex-Communist) factions of the union. The article argues that through the changed legal meaning of the provision, the union was able to transform concession bargaining into a basis for partnership. The internal discontent about this issue is nonetheless substantial and a threat to the unity of the union, both locally and at the union level. On the basis of the results of the articles, other factors influencing representativeness, such as technology and EU law and an overview of the main changes in the Finnish paper industry, it is concluded that, especially in recent years, the Finnish Paper Workers' Union has lost some of its representativeness. In particular, the loss of the efficiency of strikes is noted, the compromise on outsourcing which may have alienated a substantial part of the union's membership, and the change in the collective agreement of 2008 have caused this decline. In the latter case, the internal disunion on that issue shows the constraints of the union's internal democracy. Furthermore, the failure of the union to join the TEAM industrial union (by democratic means), the internal conflicts and a narrow focus on its own sector may also hurt the union in the future, as the paper industry in Finland is going through a structural change. None of these changes in representativeness would have been so drastic without the considerable pressure of globalization - in particular changing markets, changing technology and a loss of domestic investments to foreign investments, which in the end have benefited the corporations more than the Finnish employees of these corporations. Taken together, the union risks becoming socially irrelevant in time, though it will remain formally very strong on the basis of its institutional setting and financial situation.
