Eosinophilic esophagitis-endoscopic distinguishing findings
Get PDFEosinophilic esophagitis (EE) is the most frequent condition found in a group of gastrointestinal disorders called eosinophilic gastrointestinal diseases. The hypothetical pathophysiological mechanism is related to a hypersensitivity reaction. Gastroesophageal reflux disease-like complaints not ameliorated by acid blockade or occasional symptoms of dysphagia or food impaction are likely presentations of EE. Due to its unclear pathogenesis and unspecific symptoms, it is difficult to diagnose EE without a strong suspicion. Although histological criteria are necessary to diagnosis EE, there are some characteristic endoscopic features. We present the case of a healthy 55-year-old woman with dysphagia and several episodes of esophageal food impaction over the last six months. This case report stresses the most distinguishing endoscopic findings-mucosa rings, white exudative plaques and linear furrows-that can help in the prompt recognition of this condition

Get PDFGranuloma eosinofílico na clavícula. Apresentação atípica de uma patologia rara
Get PDFO granuloma eosinofílico de localização óssea é uma lesão benigna e apresenta geralmente um curso indolente. Esta entidade foi descrita em 1940 por Lichtenstein e Jaffe e a sua etiologia permanece desconhecida, sendo sugerida a sua associação a outros síndromes. A sua localização mais comum é a nível do crânio, fémur e coluna vertebral e pode apresentar-se como uma lesão simples ou lesões múltiplas. Tem geralmente bom prognóstico, não havendo contudo um consenso quanto ao seu tratamento. Os autores presentam o caso de um homem de 36 anos que apresentava um granuloma eosinofílico de localização atípica – a clavícula – complicado com fratura patológica. Foi submetido a tratamento cirúrgico com excisão da massa tumoral e estabilização com placa e enxerto de ilíaco tricortical autólogo. Foi conseguido um excelente resultado funcional que se mantinha no follow-up a três anos. Não existe na literatura, ao conhecimento dos autores, qualquer descrição de um caso de fratura patológica na apresentação de um granuloma eosinofílico
Transvesical natural orifice transluminal endoscopic surgery (NOTES) nephrectomy with kidney morcellation: a proof of concept study
Get PDFStudy Type - Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Until now, the transvaginal approach has been the only method of removing larger specimens from the abdominal cavity using natural orifice transluminal endoscopic surgery. There has been no means of extracting larger specimens in men and the means are restricted even in women, particularly in young women. The present study shows that the difficulty of large specimen retrieval can be overcome, irrespective of the diameter of the chosen port, through natural orifices using morcellation.
OBJECTIVE:
To show, in a porcine model, the feasibility of a complete transvesical natural orifice transluminal endoscopic surgery (NOTES) nephrectomy with kidney extraction after morcellation through the same port.
MATERIALS AND METHODS:
Transvesical nephrectomy and morcellation were performed in six pigs at Minho University, Braga, Portugal after institutional review board approval. The transvesical port and the cystotomy were created under the guidance of a ureteroscope, while the remaining steps were done under the guidance of an operating telescope. Dissection of the renal vessels and kidney was performed using dissection grasping forceps and a vessel sealing system (LigaSure(™) ; Covidien, Mansfield, MA, USA) and morcellation was done using a Piranha(™) morcellator (Richard Wolf, Knittlingen, Germany).
RESULTS:
There were no complications related to the creation of transvesical access. The image provided by the telescope was superior to that of the ureteroscope, especially underwater. Morcellation was quick and effective, with the support of a fixing needle through the abdominal wall, designed to fix the kidney, after laceration of a bowel loop occurred in the first experiment. It was found that technical improvements are needed to ensure safety of NOTES morcellation.
CONCLUSIONS:
Kidney morcellation after nephrectomy, using a natural orifice exclusively, is feasible. Despite technical limitations, this proof of concept study can be regarded as a potential step towards the application of NOTES in urology
Hernioplasty in One-Day Surgery: result of 228 self-adhesive prosthesis
Get PDFAim: To evaluate the outcomes of inguinal hernia repair with ProGrip® mesh in same-day surgery
Methods: Follow-up data was collected at 24 hours and 30 days after
surgery.
Results: In one year, 228 patients underwent surgical repair of unilateral inguinal hernia. At 24 hours after surgery, 50.64% of patients reported some degree of pain and 66.3% were able to move around the house
with few limitations. Thirty days after surgery, 94.39% of patients had
returned to their routine activities.
Conclusions: The use of the ProGrip® mesh is associated with low post-operative pain and rapid recovery

Get PDFRemote cardiac ischemic conditioning: Underlying mechanisms and clinical applications
Get PDFDespite a significant improvement in the care of acute coronary disease, mortality and morbidity remain important. One explanation for this lies in the fact that the very coronary reperfusion may paradoxically result in additional myocardial injury, through the so-called ischemia-reperfusion injury, partially mitigating the beneficial effects of myocardial reperfusion. Over the past two decades, numerous pharmacological interventions (such as the use of antioxidants, anti-inflammatory, magnesium, glucose/insulin/potassium, rapid normalization of pH) were studied in order to prevent ischemia-reperfusion injury. Despite the promising results obtained in animal experiments, attempts to transpose these results to humans, and consequently to clinical practice, have been disappointing. On the other hand, cardiac ischemic conditioning is an intervention that has produced positive results. Ischemic conditioning refers to the protection induced by short periods of ischemia followed by reperfusion, prior to a major ischemic event. Ischemic stimulus can be applied before (pre-conditioning), during (per-conditioning) or after (post-conditioning) the major ischemic event. An important finding regarding cardiac ischemic conditioning, was that protection could be induced remotely, introducing the concept of remote ischemic conditioning. In this paper, we proposed to review the mechanisms underlying remote ischemic cardiac conditioning and the possible clinical applications, considering more specifically pre and per-conditionin
