Ureteroscopy in Pregnant Women for Ureteral Stone

Introduction: The occurrence of urolithiasis in pregnancy represents a challenge in both diagnosis and treatment of this condition, because it presents risks not only to the mother but also to the fetus. Surgical treatment may be indicated for patients with infection, persistent pain, and obstruction of a solitary kidney. We present our experience on the management of pregnant patients with ureteral calculi and a review of the literature.Materials and Methods: The charts of 19 pregnant patients with obstructive ureteral calculi were retrospectively reviewed. Gestational age ranged from 13 to 33 weeks. In all patients, ureteral stone was diagnosed on abdominal ultrasound. In regard to localization, 15 calculi were in the distal ureter, 3 in the proximal ureter, and 1 in the interior of an ureterocele. Calculi size ranged from 6 to 10 mm (mean, 8 mm). The following criteria were used to indicate ureteroscopy: persistent pain with no improvement after clinical treatment, increase in renal dilation, or presence of uterine contractions. Nine patients (47.3%) were submitted to ureteroscopy. All calculi (100%) were removed with a stone basket extractor under continuous endoscopic vision. None of the calculi demanded the use of a lithotriptor.Results: Nine patients (47.3%) treated with clinical measurements presented no obstetric complications and spontaneous elimination of the calculi. Nine patients (47.3%) submitted to ureteroscopy had no surgical complications. There was remission of pain in all cases after ureteroscopy and ureteral catheter placement.Conclusion: The diagnosis and treatment of ureteral lithiasis in pregnant women present potential risks for the fetus and the mother. Conservative management is the first option, but ureteroscopy may be performed with safety and high success rates.

Surgical procedures used for post-traumatic neurogenic bladder in a cat: report case

Um gato de um ano de idade, macho, castrado, sem raça definida, foi encaminhado ao Hospital Veterinário Escola para avaliação de retenção urinária associada à subluxação nas vértebras T12-T13, que foi causada por um acidente automobilístico. Realizou-se a denervação do esfíncter uretral, por transecção dos nervos pudendo e hipogástrico, para permitir o esvaziamento da bexiga, porém três meses após a cirurgia inicial o animal apresentou recorrência da retenção urinária. Esfincterotomia endoscópica uretral foi então realizada, resultando em incontinência urinária por quatro meses.

Lesions (ulcers and/or erosions) and desquamations location in the gastric mucosa from asymptomatic Quarter Horse foals: endoscopic survey

A úlcera gástrica figura como uma importante causa de desconforto abdominal em eqüinos jovens. de acordo com a localização das lesões na mucosa gástrica, a presença ou ausência de sinais clínicos e possíveis complicações resultantes de sua ocorrência, quatro síndromes clínicas são freqüentemente descritas em potros: 1) Úlceras assintomáticas ou silenciosas; 2) Úlceras sintomáticas ou ativas; 3) Úlceras perfuradas; e 4) Obstruções gástrica ou duodenal. Com o objetivo de se verificar a distribuição de lesões gástricas (úlceras e/ou erosões) e descamações do epitélio aglandular no estômago de eqüinos jovens assim como uma possível relação entre as alterações mencionadas (lesão/descamação) sessenta potros da raça Quarto de Milha não-portadores de sinais clínicos compatíveis com úlceras gástricas foram submetidos à gastroscopia. Os potros foram divididos em quatro faixas etárias de 15 animais cada uma, sendo: 1 a 30 dias, 31 a 60 dias, 61 a 90 dias e 91 a 120 dias de idade. As lesões ocorreram em ordem decrescente de freqüência nas regiões aglandular próximo ao margo plicatus ao longo da curvatura maior, aglandular próximo à cárdia ao longo da curvatura menor, fundo glandular e aglandular e antro. As descamações do epitélio aglandular ocorreram de forma similar nas regiões de fundo e margo plicatus. Não houve associação entre a ocorrência de lesões e descamações.

Espécies reativas do oxigênio e as doenças respiratórias em grandes animais

As espécies reativas do oxigênio (ERO) são moléculas instáveis e extremamente reativas capazes de transformar outras moléculas com as quais colidem. As ERO são geradas em grande quantidade durante o estresse oxidativo, condição em que são afetadas moléculas como proteínas, carboidratos, lipídeos e ácido nucleicos. Neste trabalho, são discutidos os principais conceitos sobre os radicais livres e as ERO: principais tipos, sua formação e a forma como atuam sobre as estruturas celulares, provocando lesão tecidual significativa. Os principais sistemas de defesa antioxidantes e a influência do aumento na produção dessas ERO no trato respiratório de grandes animais também são discutidos, dando ênfase ao envolvimento das ERO em doenças como a pneumonia em ruminantes e na obstrução recorrente das vias aéreas e a hemorragia pulmonar induzida por exercício em equinos.

Papilomatose oral em cães: revisão da literatura e estudo de doze casos

Canine papillomatosis is an infectious viral disease characterized by oral, cutaneous or ocular papillomas, usually benign. The treatment is indicated in animals, with multiple tumors that produce pharyngeal obstruction, and problems, of eating or for aesthetic reasons. Different treatment protocols have been proposed, including surgical excision, cryosurgery, electro surgery, autogenous or recombinant vaccines, imunomodulators drugs, systemic and intralesional chemotherapy. In this study were reviewed the more important aspects of canine oral papillomatosis. In the 12 studied animals, the papillomas were observed predominantly in mouth, gum and palate regions, in puppies until 12 months, presenting combined infection with ehrlichiosis. The treatment using Propionibacterium acnes and/or autogenous vaccine showed efficacy in eight dogs (66.7%).

Tétano em um gato

Relata-se neste artigo o caso de tétano em um gato macho de 3 anos 8 dias após a realização de orquiectomia bilateral, onde o histórico do animal associado aos achados clínicos e laboratoriais propiciaram a definição do diagnóstico. Mesmo após tratamento, o quadro evoluiu para tetania generalizada e óbito. Neste caso, a ação da neurotoxina na musculatura estriada esquelética do esfíncter uretral foi um fator agravante para a doença, levando à retenção vesical e azotemia pós-renal.

Ultrastructure of the urethra of the Mongolian gerbil

Objective: the urethra is the main port of entry of sexually transmitted pathogens. However, papers on the morphology of the urethra are scarce. The Mongolian gerbil is a rodent native of the Mongolia and China and has been utilized as a laboratory animal since the 1960s. This work describes the ultrastructure of the urethra of the Mongolian gerbil to provide data for future experimental studies. Methods: the urethra of ten adult male gerbils was studied by transmission electron microscopy. Results: the epithelium of the pelvic urethra possesses two cell types: I and II, without the formation of cellular layers, while the penile urethra possesses cellular layers: basal, intermediate and superficial. The urethra presents neurosecretory cells belonging to the amine precursor uptake and decarboxylation system. Conclusions: the urethral epithelium of the gerbil is a neurosecretory epithelium, part of the amine precursor uptake and decarboxylation system.

Fixed points on torus fiber bundles over the circle

The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S-1 for spaces which axe fibrations over S-1 and the fiber is the torus T. For the case where the fiber is a surface with nonpositive Euler characteristic, we establish general algebraic conditions, in terms of the fundamental group and the induced homomorphism, for the existence of a deformation of a map over S-1 to a fixed point, free map. For the case where the fiber is a torus, we classify all maps over S-1 which can be deformed fiberwise to a fixed point free map.

Fixed points on Klein bottle fiber bundles over the circle

The main purpose of this work is to study fixed points of fiber-preserving maps over the circle S(1) for spaces which are fiber bundles over S(1) and the fiber is the Klein bottle K. We classify all such maps which can be deformed fiberwise to a fixed point free map. The similar problem for torus fiber bundles over S(1) has been solved recently.

Obstrução intestinal e enterotomia em tigre d’água (Trachemys dorbignyi)

Intestinal obstruction occurs in chelonian mainly due parasitism and foreign bodies, as stones and sand. An intestinal compaction was described in a five year-old male d'orbigny's slider which was taken to the Veterinary Medical Teaching Hospital of the UNICASTELO, at Fernandopolis, SP, Brazil, presenting anorexia for a week, severe dehydration and stupor. Definitive diagnostic was performed by radiographic exam and great amount of intestinal radiopac substance was detected. The animal went through emergency celiotomy for removing the intestinal foreign bodies. Inhalatory anesthesia with isofluorane was used for anesthesia induction and manutention. After local antisepsy, a 4cm(2) oblique opening was conducted on plastron by using a vibratory saw. Peritoneum was cut, intestines exteriorized and enterotomy performed. During the surgery, the animal was radiographed to confirm the complete taken out of the foreign bodies. Mononylon 4-0 strand was applied for intestinal suture in two planes. The plastron piece that was taken out was replaced and set with epoxy resine and gaze on the surgical window, making it waterproof. In the postoperative time, animal was medicated with analgesics for two days and pentabiotics for five days. Oral creamy diet was used with oral tube from the second to tenth day, what provided a great clinicosurgical recovering.

Detection of Altered Risk Factors in Hospitalized Patients with Coronary Artery Disease

OBJECTIVE: To assess biochemical, anthropometric, and dietary variables considered risk factors for coronary artery disease. METHODS: Using anthropometrics, dietary allowance, and blood biochemistry, we assessed 84 patients [54 males (mean age of 55± 8 years) and 30 females (mean age of 57±7 years)], who had severe ( > or =70% coronary artery obstruction) and nonsevere forms of coronary artery disease determined by cardiac catheterization. The severe form of the disease prevailed in 70% of the males and 64% of the females, and a high frequency of familial antecedents (92% ' 88%) and history of acute myocardial infarction (80% ' 70%) were observed. Smoking predominated among males (65%) and diabetes mellitus among females (43%). RESULTS: Males and females had body mass index and body fat above the normal values. Females with nonsevere lesions had HDL > 35 mg/dL, and this constituted a discriminating intergroup indicator. Regardless of the severity of the disease, hyperglycemia and hypertriglyceridemia were found among females, and cholesterolemia > 200 mg/dL in both sexes, but only males had LDL fraction > 160 mg/dL and homocysteine > 11.7 mmol/L. The male dietary allowance was inadequate in nutrients for homocysteine metabolism and in nutrients with an antioxidant action, such as the vitamins B6, C, and folate. Individuals of both sexes had a higher lipid and cholesterol intake and an inadequate consumption of fiber. The diet was classified as high-protein, high-fat, and low-carbohydrate. CONCLUSION: The alterations found had no association with the severity of lesions, indicating the need for more effective nutritional intervention.
