Com a evolução do quadro, ocorre parada na filtração glomerular e, consequentemente, desenvolvem-se várias alterações nos equilíbrios hídrico, eletrolítico e ácido-básico, além do acúmulo de metabólitos nitrogenados e toxinas orgânicas. Podem ocorrer modificações histopatológicas nos rins e na bexiga. Objetivou-se, neste estudo, caracterizar prospectivamente as alterações laboratoriais e histopatológicas de ratos apresentando obstrução uretral. Para tanto, foram utilizados 21 ratos Wistar com obstrução uretral induzida. Foram realizados os seguintes exames: hemogasometria venosa e determinação dos níveis de uréia, creatinina, sódio, potássio, cloreto, cálcio e fósforo. As avaliações foram repetidas a cada 8 horas durante 24 horas. Após esse período os animais foram eutanasiados e as bexigas e os rins enviados para exame histopatológico. Entre os exames bioquímicos, foram observadas elevações estatisticamente significativas nos níveis de uréia, creatinina, fósforo, magnésio e potássio, e diminuição nos níveis de cloreto. Com relação à hemogasometria, houve diferença estatisticamente significativa entre os valores de pH, PO2, PCO2, excesso de base, saturação de oxigênio e lactato. O exame histopatológico renal revelou a presença de alterações tubulares e glomerulares, enquanto a análise histopatológica das bexigas demonstrou a presença de hemorragia, separação de fibras musculares e infiltrado inflamatório. Conclui-se que a obstrução uretral provoca alterações que podem ser detectadas nos exames laboratoriais, sendo as mesmas agravadas no decorrer do tempo. Além disso, a persistência durante 24 horas é capaz de levar a alterações morfológicas no trato urinário. / Urethral obstruction is a frequent emergency in Veterinary clinics. The persistent urethral obstruction leads to blockage of renal filtration, resulting in several alterations in fluid, electrolyte and acid-base balance, besides the accumulation of nitrogenous metabolic products and organic toxins. Histopathological changes may occur in the kidneys and urinary bladder. Thus, this study aimed to prospectively characterize renal and vesical histopathological alterations in rats due to urethral obstruction. Twenty-one male Wistar rats (Rattus norvegicus) with experimental urethral obstruction were included in the study. Venous gasometry and determination of urea, creatinine, sodium, potassium, chloride, calcium and phosporus were performed. The avaliations were repeted each 8 hours during 24 hours. After that period, the animals were euthanatized for the collection of kidneys and bladder fragments to the histopathological exam. Biochemistry exams demonstrated statiscally significant elevations for the levels of urea, creatinine, phosporus, magnesium and potassium, and a decrease for the levels of chloride. Results of gasometry also demonstrated statiscally significant changes for pH, PO2, PCO2, base excess, oxygen saturation and lactate values. Histopathology analysis revealed kidney alterations in tubular and glomerular elements. The most important alterations found in urinary bladders were transmural hemorrhage, separation of muscle fibers and neutrophilic inflammatory infiltrate. Complete urethral obstruction induces important changes that can be detected by laboratorial exams, and the alterations worsen with the course of time. Besides that, the persistent obstruction during 24 hours is able to cause morphological changes in the kidneys and urinary bladder, which can be detected using histopathological exam.

Avaliação da incidência e evolução das manifestações das doenças nasais em pacientes portadores de fibrose cística. 2018. Dissertação (Mestrado) – Faculdade de Medicina de Botucatu, Universidade Estadual Paulista “Júlio de Mesquita Filho”, Botucatu, 2018. Introdução: A fibrose cística é uma doença originada da mutação do gene responsável pela codificação da proteína CFTR. A ausência ou defeito dessa proteína leva a um transporte irregular de sal e água em células mucosas respiratórias e de glândulas exócrinas podendo resultar em diversas manifestações clínicas. As alterações otorrinolaringológicas frequentes são rinossinusite crônica e polipose nasal. Objetivo: Avaliar a incidência e a evolução de doenças nasais em pacientes portadores de fibrose cística com exame videonasolaringoscópico documentado em prontuário do período de agosto de 2015 a agosto de 2017. Casuística e Métodos: Realizou-se a coleta de dados de 65 pacientes acompanhados no ambulatório de fibrose cística do Hospital das Clínicas de Botucatu. Foram incluídos os pacientes que possuíam exames videonasolaringoscópicos realizados durante o período de acompanhamento e que concordaram em participar do estudo. Realizou-se um estudo de coorte com avaliação dos dados epidemiológicos, presença de comorbidades, achados nos exames videonasolaringoscópicos, positivação de cultura de orofaringe e resposta ao tratamento clínico. Resultados: Foram analisados 51 pacientes. A mutação delta F508 esteve presente em 20 pacientes. As comorbidades avaliadas foram: bronquiectasias (n= 39), pneumonia (n= 29), íleo meconial ao nascimento (n=9), hepatopatia (n= 22) e insuficiência pancreática (n= 32). Nos exames videonasolaringoscópicos encontramos: 19 pacientes com pólipos nasais (37,2%), destes, treze tiveram resposta positiva com o tratamento com corticoide tópico nasal. Doze pacientes possuiam hipertrofia adenoideana (23,5%), oito pacientes tinham secreção purulenta em cavidades nasais (15,7%), 40 pacientes possuíam alteração na mucosa nasal. O microorganismo mais frequente nas culturas de orofaringe foi a Pseudomonas aeruginosa (72,5%). Não encontramos relação entre a presença de pólipos nasais e complicações pulmonares; entre a positivação da cultura de orofaringe para Pseudomonas aeruginosa e presença de pólipos nasais; e entre as complicações pulmonares e a positivação de cultura de orofaringe para Pseudomonas aeruginosa. Conclusão: A incidência de polipose nasal observada neste estudo foi de 37,2%. O exame videonasolaringoscópico permite a detecção precoce da polipose nasal nesta população. / CAMPOS, C.S.M. 2018. Evaluation of the incidence and evolution of the manifestations of nasal diseases in patients with cystic fibrosis. 2018. Thesis (Master) – Botucatu Medical School, Universidade Estadual Paulista “Júlio de Mesquita Filho”, Botucatu, 2018. Introduction: Cystic fibrosis is a disease originated from the mutation of the gene responsible for the coding of the CFTR protein. The absence or defect of this protein leads to an irregular transport of salt and water in respiratory mucous cells and exocrine glands, resulting in several clinical manifestations. Frequent otorhinolaryngological changes are chronic rhinosinusitis and nasal polyps. Objective: To evaluate the incidence and evolution of nasal diseases in patients with cystic fibrosis with a videonasolaryngoscopic exam documented in medical records from August 2015 to August 2017. Casuistry and Methods: Data were collected from 65 patients followed in the cystic fibrosis outpatient clinic Botucatu Medical School. Patients who had videonasolaryngoscopic examinations performed during the follow-up period and who agreed to participate in the study were included. A cohort study was conducted with epidemiological data, presence of comorbidities, findings in videonasolaryngoscopic examinations, oropharyngeal culture positivity and response to clinical treatment. Results: Fifty-one patients were analyzed. The delta F508 mutation was present in 20 patients. The comorbidities evaluated were: bronchiectasis (n = 39), pneumonia (n = 29), meconium ileus at birth (n = 9), liver disease (n = 22) and pancreatic insufficiency (N=32) . In the videonasolaringoscopic exams we found: 19 patients with nasal polyps (37.2%), of whom thirteen had a positive response to nasal topical corticosteroid treatment. Twelve patients had adenoid hypertrophy (23.5%), eight patients had purulent secretion in nasal cavities (15.7%), and 40 patients had alterations in the nasal mucosa. The most frequent microorganism in oropharynx cultures was Pseudomonas aeruginosa (72.5%). We did not find a relation between the presence of nasal polyps and pulmonary complications; between the positivity of the oropharynx culture for Pseudomonas aeruginosa and the presence of nasal polyps; and between pulmonary complications and the positivity of oropharynx culture for Pseudomonas aeruginosa.Conclusion: The incidence of nasal polyposis observed in this study was 37.2%. The videonasolaringoscopic examination allows the early detection of nasal polyposis in this population.

L’occlusion colique est le mode de révélation de 8 à 29% des cancers du colon. Elle révèle undiagnostic tardif associé le plus souvent à une tumeur localement avancée ou métastatique. Laprise en charge, en urgence, de ces cancers est donc cruciale et doit intégrer l’évaluation del’état général du patient (âge, comorbidités, état nutritionnel), et le stade de la maladie quiauront un impact direct sur les résultats postopératoires précoces et à distance. Les optionsthérapeutiques disponibles pour la prise en charge en urgence de ces tumeurs sontchirurgicales (colostomie de décharge, intervention de Hartmann, colectomie segmentaireavec ou sans lavage per opératoire avec anastomose colorectale, colectomie totale avecanastomose iléorectale) ou endoscopique (prothèse colique).Les objectifs de cette thèse étaient d’évaluer l’impact de la prothèse colique sur la prise encharge à visée curative des cancers coliques en occlusion, l’étude des donnéesanatomopathologiques afin d’expliquer les différences de survie en fonction de la stratégiethérapeutique et l’élaboration de recommandations françaises et européennes afin de préciserla place de la prothèse colique dans la prise en charge des cancers coliques en occlusion / The colonic obstruction is the mode of revelation of 8 to 29% of colon cancers. It reveals latediagnosis most often associated with a tumor locally advanced or metastatic disease. Themanagement, in an emergency, of these cancers is crucial and must include the evaluation ofthe patient's general condition (age, comorbidities, nutritional status), and the stage of thedisease that will have a direct impact on early and late postoperative outcomes. Treatmentoptions available totreat in emergency these tumors are surgical (colostomy, Hartmannprocedure, segmental colectomy with or without intraoperative lavage with colorectalanastomosis, total colectomy with ileorectal anastomosis) or endoscopic (colonic stent).The objectives of this thesis were to assess the impact of the colonic stent in the curativemanagement of obstructive colonic cancer, to study pathological data to explain differences insurvival according to treatment strategy and the development of French and Europeanrecommendations to clarify the role of colonic stent in the treatment of colon cancerocclusion

Percutaneous endoscopic gastrostomy (PEG) tube placement is one of the methods of providing enteral nutrition support and is often used in critically ill patients. There are several complications of PEG tube placement, including intussusception. Jejunojejunal and retrograde jejunoduodenogastric intussusception are well-documented complications of PEG tube placement. Here we describe the case of a 25-year-old female who was diagnosed with anterograde gastroduodenal intussusception with the PEG tube acting as a lead point. Our case is unique as, to the best of our knowledge, there are no documented cases of PEG tube-related anterograde gastroduodenal intussusception. The reported patient was found to have extensive gastric pneumatosis and portal venous gas concerning for acute ischemia. Such cases warrant immediate surgical intervention. However, in our case, the patient's family opted for comfort care measures.

Colorectal cancer is one of the leading causes of cancer related deaths in western world. While most common site for metastasis for colon cancer is liver, lung, and the peritoneum, metastasis to various other organs such as brain, bones and thyroid has been reported. Metastatic lesions to the small bowel are more common than primary lesions and most common primary neoplasms that metastasize to the duodenum are lung cancer, renal cell carcinoma, breast cancer, and malignant melanoma. We report a very rare case of recurrent adenocarcinoma of colon metastasizing to duodenum after 2 years of curative resection of primary cancer. Surgical resection for curative intent as well as palliative management is recommended.
