No full textSurgical treatment of isolated lung and adrenal metastasis from colorectal cancer. Case report.
No full textINTRODUCTION:
Up to 30% of stage I and II colorectal cancers (CRCs) treated with surgical resection alone show disease recurrence, indicating that lymph node (LN) involvement was probably underestimated. Lung is a common site of CRC metastasis, whereas adrenal glands are rarely involved.
CASE REPORT:
On July 2004 a 56-year old woman underwent left hemicolectomy for a stage I sigmoid cancer. Four years later a lobectomy was performed for an isolated lung metastasis; thirteen months thereafter she underwent left adrenalectomy for adrenal metastasis. No lymph node involvement has ever been demonstrated either histopathologically or radiologically. At present, the patient is alive and apparently disease-free.
DISCUSSION:
The presence of LN occult metastasis, that might explain recurrence in stage I and II CRCs, has recently been investigated by means of immunohistochemistry and polymerase chain reaction; evidence of LN metastasis obtained with the latter technique is associated to a worse outcome. There have been very few cases that resemble our patient's neoplastic progression and they were either stage III neoplasms or rectal cancers. Our patient's primitive localization in the sigmoid colon makes it difficult to imagine why the liver has not been a site of metastasis. Finally, surgery has an important role in treating isolated metastasis in both lungs and adrenal glands. KEY WORDS: Colorectal cancer, Lung metastasis, Solitary adrenal metastasis
Hemorrhagic Cholecystitis. Report of a case with comprensive literature review and treatment algorithm
Full text linkHemorrhagic Cholecystitis is a rare condition and usually represents a complication of acute cholecystitis. The clinical presentation is quite overlapping and usually involves abdominal pain that may be associated with fever, jaundice, nausea, vomiting, and finally haemobilia. It frequently involves patients with preexisting conditions such as chronic kidney disease undergoing hemodialysis or anticoagulation therapy. Due to the deadly potential of this condition attention must be high during diagnostics and treatment in order to avoid an ill-fated conclusion. To our knowledge, there is a lack of a comprehensive review on the subject as most of the literature consists of case reports or small case series. In order to give a contribution to improving the treatment strategy of this condition, we report a case successfully treated with cholecystectomy, and performed a literature review. Using the term "Hemorrhagic Cholecystitis", on PubMed database we found 67 cases reported in the English literature. The cases were analyzed by two researchers and clinical information was extrapolated and organized, aiming to create a comprehensive review on the subject, that may be clear and useful in clinical practice. KEY WORDS: Hemorrhagic cholecystitis, Surgical treatment
Incisional hernia surgery: report on 283 cases
No full textBackground and Objectives: Despite the improvement of the surgical technique and several experiences reported in literature about prosthetic incisional hernioplasty, the prevalence rate of recurrence and of the classic complications has not changed over the years. We analyze our caseload, establishing some technical cornerstones in order to reduce their occurrence. Patients and Methods: 283 patients underwent incisional hernioplasty in our Department of Surgery in the decade 1999-2008. They were retrospectively divided into four groups (A-D) according to the surgical technique adopted for a comparative analysis: A, 37 primary direct closure; B, 207Rives-Stoppa procedures; C, 9 Chevrel procedures; D, 30 intraperitoneal repairs. The outcomes were considered in terms of postoperative surgical complications. Results: In total, we observed 11 cases of hernia recurrence (3.9%), 13 cases of infections (4.6%), 7 cases of seroma/hematoma (2.4%) and one case of acute respiratory insufficiency. Discussion: The Rives-Stoppa procedure is, among all those practised, the treatment of choice in incisional hernioplasty. Thanks to the introduction of some simple modifications to this technique and preventing the postoperative infections, we obtained excellent results in terms of recurrence rate (only 1 case on 207 patients, 0,48%) and morbidity

No full textSurgical treatment of renal carcinoma with atrial tumor thrombus avoiding cardiopulmonary bypass: step-by-step description
No full textTumor thrombus in the inferior vena cava (IVC) occurs in 4-10% of patients with renal cell carcinoma (RCC) and poses a challenge for the surgical team. Because there is no systemic therapy available to significantly reduce tumor burden, surgical intervention is the only treatment. However, the surgical approach is associated with significant morbidity and mortality. When the thrombus extends above the diaphragm, the use of cardiopulmonary bypass (CPB) and accompanying deep hypothermic circulatory arrest (DHCA) has usually been advocated. However, complications inherent to CPB and DHCA, such as coagulopathy and central nervous system complications, have led us to search for an alternative surgical approach to these tumors. The purpose of this study is to describe the surgical technique used in five patients with large RCC with tumor thrombus extending into the supradiaphragmatic IVC and Right atrium (RA), Right atrium, who underwent extensive resection without CPB and DHCA
Multiple organ failure associated with Coxsackie virus in a kidney transplant patient. Case report
No full textINTRODUCTION:
Viral myocarditis can emerge with various symptoms, including fatal arrhythmia and cardiogenic shock, potentially evolving in chronic myocarditis or dilatative cardiomyopathy. We report a case of a kidney transplant patient affected by coxsackie viral myocarditis.
METHODS:
A 49-year-old man was admitted to our hospital with dyspnea and fever in August 2014. He underwent living donor kidney transplantation in 1986 and polar graft resection for papillary carcinoma in 2012.
RESULTS:
The initial investigation showed pulmonary congestion, pancreatitis, increased serum troponin I, and increased liver enzyme levels. Echocardiogram revealed an ejection fraction (EF) of 20% and PAPS 45 mm Hg. He underwent coronary stent implantation, started hemodialysis, and continued on low-dose steroid immunosuppressive therapy. The clinical course improved rapidly, but endomyocardial biopsy showed acute myocarditis. Further investigation revealed a high antibody titer against coxsackievirus B4 and B5. Pancreatic enzyme levels normalized 2 months after patient admission; his cardiac condition improved after 6 months. The patient has been followed for 1 year, and his left ventricular EF is stable (45%).
CONCLUSIONS:
Viral myocarditis represents a serious clinical condition requiring a fast therapeutic intervention. This patient's clinical course suggests that changes in his immunosuppressive therapy were associated with progressive amelioration of his viral myocarditis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
