Multidrug-resistant Escherichia coli isolated from a dog with a history of urolithiasis: case report / Escherichia coli multirresistente isolada de cão com histórico de urolitíase: relato de caso

Bacterial resistance is a reality in both human and veterinary health, it limits the therapeutic arsenal and raises the costs of the patient's treatment. A dog with signs of cystitis received treatment with 5mg/kg enrofloxacin at three consecutive times, with low effectiveness. The presence of urethral uroliths was identified and urohydropulsion was done. The animal presented a new obstruction, for which a cystotomy was performed, but continued with signs of infection. Uroculture and antimicrobial susceptibility test were then performed. Escherichia coli was identified, which was resistant to 13 antibiotics, being sensitive only to piperacillin-tazobactam and amikacin. In the screening test for ß-lactamase, the production of ESßL was detected. The qPCR indicated the presence of the bla CTXm, bla DHA, bla OXA, bla IMP, bla TEM, bla GIM, bla SIM, bla SPM and bla SME genes, which may lead to a phenotypic resistance profile for ampicillin, amoxicillin-clavulanate, aztreonam, cefepime cefoxitin, cefuroxime, ceftazidime, ceftriaxone, imipenem, and piperacillin-tazobactam. This case reaffirms the value that laboratory analysis adds to the diagnosis and treatment of cystitis and urolithiasis, which can define the direction of evolution of the prognosis and the speed at which the patient's health will be restored.(AU)

A resistência bacteriana aos antibióticos é uma realidade, tanto na saúde humana quanto veterinária, limita o arsenal terapêutico e eleva os custos relacionados ao tratamento do paciente. Um cão, com sinais de cistite, recebeu tratamento com enrofloxacina, na dose de 5mg/kg, em três momentos seguidos, com baixa efetividade. Identificou-se presença de urólitos uretrais e foi feita uro-hidropropulsão. O animal apresentou nova obstrução, para a qual foi realizada uma cistotomia, mas continuou com sinais de infecção. Realizou-se, então, urocultura e teste de antibiograma. Foi identificada Escherichia coli, que se mostrou resistente a 13 antibióticos, sendo sensível somente à piperacilina-tazobactam e amicacina. No teste de triagem para ß-lactamase, detectou-se a produção de ESßL. A qPCR indicou presença dos genes blaCTXm, blaDHA, blaOXA, blaIMP, blaTEM, blaGIM, blaSIM, blaSPM e blaSME, que podem conduzir um perfil fenotípico de resistência para ampicilina, amoxicilina-ácido clavulânico, aztreonam, cefepima, cefoxitina, cefuroxima, ceftazidima, ceftriaxona, imipenem, piperacilina-tazobactam. Este caso reafirma o valor que a análise laboratorial agrega ao diagnóstico e tratamento da cistite e da urolitíase, podendo definir o sentido de evolução do prognóstico e a velocidade em que a saúde do paciente será restabelecia.(AU)

Pseudotumor vesical a causa de un dispositivo intrauterino / Vesical pseudotumor due to an intra-uterine device

Se describe el caso clínico de una paciente atendida en el Hospital Oncológico Docente Provincial Conrado Benítez García de Santiago de Cuba por presentar una perforación en la vejiga y desplazamiento de un dispositivo intrauterino hacia la cavidad vesical, lo cual generó la formación de litiasis y, consecuentemente, la aparición de frecuentes infecciones urinarias y dolor en bajo vientre, sin mejoría alguna ante la terapéutica aplicada. Se decidió realizar una cistotomía para extraer la litiasis compacta junto con la T de cobre; la paciente evolucionó favorablemente y los síntomas desaparecieron

The case report of a patient assisted in Conrado Benítez García Teaching Provincial Cancer Hospital in Santiago de Cuba is described, due to a bladder perforation and displacement of an intra-uterine device toward the vesical cavity, which generated the lithiasis formation and, consequently, emergence of frequent urinary infections and pain in lower abdomen, without any improvement with therapy. It was decided to carry out a cystotomy to extract the lithiasis compacted with the copper T; the patient had a favorable clinical course and the symptoms disappeared

Mitomicina C: Una Nueva Alternativa para la Estenosis de Cuello Vesical / Mitomycin C: A New Alternative for Bladder Neck Stenosis

Introducción: La mitomicina C es un agente quimiotera-péutico en virtud a su actividad antiproliferativa y anti-biótica. Se evalúa el resultado de la cervicotomía radial endoscópica combinada con la inyección intralesional de mitomicina C para el tratamiento de las estenosis severas de cuello vesical luego del fracaso del trata-miento tradicional. Materiales y método: Revisión retrospectiva de los pa-cientes con estenosis severa de cuello vesical intervenidos entre julio de 2013 y agosto de 2015 con la utilización de mitomicina C. El 54.5% de los pacientes había fracasado al menos una vez con la realización de cervicotomía interna y/o resección endoscópica de cuello vesical. En nuestra intervención se realizaron tres o cuatro incisiones endoscópicas con corte frío en el cuello de la vejiga, seguido por la inyección intralesional de 0.3 a 0.4 mg/ml de mitomicina C en cada sitio de incisión. Resultados: Un total de 11 pacientes fueron tratados con incisión endoscópica con corte frío en el cuello de la vejiga combinado con la inyección de mitomicina C. Antes de la operación, 4 pacientes (36%) eran usuarios de cistotomía. En un seguimiento medio de 9 meses (rango 1-20) 9 pacientes (82%) se encuentran con micción espontánea posterior a un procedimiento, mientras que 2 pacientes (18%) lograron dicho objetivo después de 2 procedimientos con utilización de mitomicina C. Conclusiones: El tratamiento para la estenosis del cuello vesical con cervicotomía radial endoscópica con corte frío combinada con inyección intralesional de mitomicina C, resultó en la permeabilidad del cuello vesical en el 82% de los pacientes después de 1 procedimiento y en el 100% después de 2 procedimientos. Aunque los primeros resultados son prometedores, se requiere de estudios prospectivos y aleatorizados con seguimiento prolongado en el tiempo para validar estos hallazgos.

Introduction: The mitomycin C is a chemotherapeutic agent by virtue of its antiproliferative and antibiotic ac-tivity. We evaluated the outcome of endoscopic radial cervicotomy combined with intralesional mitomycin C injection for the treatment of severe bladder neck ste-nosis after traditional treatment failure.Materials and methods: It was a retrospective review of patients with severe bladder neck stenosis who had a surgery between July 2013 and August 2015 with mi-tomycin C. The 54.5% of patients had failed at least 1 time with internal cervicotomy and/or endoscopic re-section of the bladder neck. In our intervention, three or four endoscopic incisions were performed with a cold cut in the neck of the bladder, followed by intralesio-nal injection of 0.3 to 0.4 mg / ml of the mitomycin C at each incision site.Results: A total of 11 patients were treated with endos-copic incision with a cold cut in the neck of the bladder combined with mitomycin C injection. Before the sur-gery 4 patients (36%) were cystostomy users. At a mean follow-up of 9 months (range 1-20), 9 patients (82%) had spontaneous urine after 1 procedure, while 2 patients (18%) achieved this goal after 2 procedures using mi-tomycin C.Conclusions: The treatment for bladder neck stenosis with endoscopic radial cervicotomy with cold cut com-bined with intralesional mitomycin C injection resulted in bladder neck permeability in 82% of patients after 1 procedure and 100% after 2 procedures. Although the first results are promising, some prospective and rando-mized studies with long-term monitoring are required to validate these findings.

ABSTRACT Purpose: Currently, several modalities are used to manage bladder stones. We report laparoscopic single port cystolithotomy using stone basket via pneumovesicum method.

Treatment of Recurred Iris Cyst with Laser Photocoagulation and Cystotomy

PURPOSE: To report a case of recurred iris cyst 11 years after treatment with endodiathermy, which was treated with laser photocoagulation and cystotomy followed by intraocular pressure elevation and underwent anterior chamber irrigation. CASE SUMMARY: A 46-year-old female presented to our department with decreased vision in her left eye that had persisted for several months. The patient had a history of surgical removal of an iris cyst with endodiathermy 11 years ago. Slit lamp examination showed an iris cyst adjacent to the nasal corneal limbus. The cyst was filled with turbid fluid. It distorted the pupil and threatened visual axis. Iris cystotomy (diameter larger than 500 microm) was done with diode laser photocoagulation and a neodymiumdoped yttrium aluminium garnet laser. At the same day, the patient's intraocular pressure elevated to 50 mm Hg in spite of maximal conservative treatment and went through anterior chamber irrigation. After six months, the iris cyst was adhered to corneal endothelium and disappeared. Visual acuity and intraocular pressure was within normal range. CONCLUSIONS: An iris cyst can recur after treatment with endodiathermy. Recurred iris cyst can be successfully treated with laser photocoagulation and cystotomy. However, turbid fluid inside the cyst may outflow to the anterior chamber and cause secondary ocular hypertension after treatment, so careful observation is needed.

Evaluation of intraluminal pressure in cystorrhaphies with and without intestinal serosal patch supplementation from canine cadavers

PURPOSE:To evaluate the maximal intraluminal pressure (MIP) supported by canine cadaveric urinary bladders that underwent cystotomy followed by cystorraphy, with and without serosal patching-supplementation.METHODS:Two groups (n=8 each) were formed, and in one (conventional) the cystotomy was closed with cushing pattern. In the other group (serosal), the same procedure was performed, and a piece of jejunum was used for the construction of the serosal patching over the cystorraphy. MIP was measured by means of an invasive blood pressure transducer with closed stopcock attached to a multiparameter monitor. At the end of each measurement, the bladder body circumference was assessed.RESULTS:Mean±SD MIP sustained for the conventional and serosal groups were 28.88±5.08 and 65.38±10.99 mmHg, respectively (p<0.0001). Bladder circumference did not change significantly between groups (p=0.35) and did not correlate with MIP assessed in conventional (p=0.27; r=0.4379) and serosal groups (p=0.37; r=-0.3637).CONCLUSION:Serosal patch-supplemented cystorraphies were able to sustain intraluminal pressures 55.8% higher, than nonsupplemented cystorraphies in specimens from canine cadavers.

Prune belly syndrome with urethral hypoplasia and vesico-cutaneous fistula: a case report and review of literature

Association between Prune belly syndrome [PBS] and urethral hypoplasia is an unusual condition. It is usually fatal unless there is a communication between the fetal bladder and the amniotic sac. We report a case of PBS with urethral hypoplasia and congenital vesico-cutaneous fistula in a male neonate. Patient underwent cutaneous vesicostomy and was discharged for close follow up of his renal function and for future reconstruction

A Giant Pulmonary Hydatid Cyst Treated without Lobectomy

A 20 year-old woman was admitted to our clinic complaining of dyspnea, cough, chest pain and pleural effusion. The diagnosis of pulmonary hydatid cyst was made on the basis of parasitology laboratory findings, computed tomographic results and chest radiographic findings. A giant pulmonary hydatid cyst (33x14x12 cm) was located in the left lower lobe, which involved more than 90% of the lobe. The patient was treated surgically using cystotomy and capitonnage. This is a case of a giant pulmonary hydatid cyst published in the literature, which was surgically treated without a lobectomy, by preserving the lung parenchyma.

Cistoplastia experimental em coelhos (Oryctolagus cuniculus) com peritônio bovino conservado em glicerol a 98 por cento / Experimental cystoplasty in rabbits (Oryctolagus cuniculus) with bovine peritoneum conserved in 98 percent glycerol

Neste estudo foi implantado um retalho de membrana peritoneal bovina em substituição a um fragmento da face ventral da bexiga de coelhos albinos, raça Nova Zelândia, adultos, machos não-castrados (n=12), com o intuito de avaliar o processo de reparação tecidual no que se refere à biocompatibilidade, à capacidade de reparação tecidual e a possíveis complicações. Aos sete, 14, 30 e 60 dias de pós-operatório, os animais foram eutanasiados, três em cada período, mediante o emprego de tiopental sódico (200mg kg-1), para posterior avaliação macroscópica e análise histopatológica da interface do implante com o tecido nativo. Macroscopicamente, foram observadas, em todos os períodos, aderências de estruturas adjacentes ao local do implante, presença de cálculos e ausência de sinais de rejeição. Sob microscopia de luz, aos sete, 14 e 30 dias de observação, o implante ainda estava presente, havia intensa reação inflamatória mista, neovascularização, fibroplasia e escassas fibras musculares, contudo, o epitélio e a lâmina própria não estavam reconstituídos. Aos 60 dias de avaliação, o implante não estava mais presente e todas as camadas vesicais encontravam-se reparadas. O implante foi biocompatível e forneceu arcabouço para orientação e desenvolvimento das camadas teciduais da bexiga, mediante processos de reparação, restabelecendo a estrutura do órgão.

Bovine peritoneum was utilized to replace a section of ventral face of the bladder of New Zealand rabbits, adult and entire males (n=12) with the purpose of evaluating the tissue repair process in regard of its biocompatility, scar formation ability and possible complications. The animals were euthanized at 7, 14, 30 and 60 days post operative, three in each period, by the use of sodium thiopental (200mg kg-1), followed by macroscopic evaluation and histopathological analysis of the implant interface with the native tissue. Macroscopically it was observed, in all time periods, structure adherence to the implant site, presence of calculi and absence of rejection signs. Under light microscopy at the 7th, 14th and 30th observation days, the implant was present; a mixed intense inflammatory reaction could be observed, neovascularization, fiberplasic process and rare muscle fibers, however the epithelium and sheath weren't also reconstituted. At the 60th day of evaluation the implant wasn't anymore present and all vesicle layers were repaired. The implant was biocompatible and provided the mainframe for orientation and development of the tissue layers of the bladder, through repairing processes thus reestablishing the organ's structure.

Liposarcoma metastásico en mama de origen testicular: a propósito de un caso / Liposarcoma metastatic breast of testicular origin: a purpose of a case

El liposarcoma es un tumor de la vida adulta, diagnosticado con mayor frecuencia en individuos entre los 50 y 65 años de edad. Los sitios más frecuentes de presentación son los muslos y el retroperitoneo, siendo infrecuente la localización testicular y en mamas y la asociación con otros tumores es aún más excepcional. Aquellos liposarcomas que el patólogo identifica como "bien diferenciados" no suelen dar metástasis, a su vez el cáncer de mama en el hombre es una enfermedad rara y poco frecuente que se presenta en una proporción muy baja con respecto a los diferentes tipos de cánceres, dicha entidad constituye el 0,2 1,5 por ciento de todos los tumores malignos en los hombres y aproximadamente el 1 por ciento de los cánceres mamarios en ambos sexos. El objetivo principal es reportar un caso de un paciente masculino de 55 años de edad quién refiere inicio de enfermedades de 23 años de evolución caracterizada por pequeño aumento de tamaño en mama izquierda y la cual hace 4 años ha aumentado rápida y progresivamente de tamaño; concomitantemente presenta aumento de tamaño en región testicular y tumoración en mama derecha realizándosele biopsias en dichas zonas resultando compatible con liposarcoma bien diferenciado.

Initial experience with 10 cases of Indiana pouch continent urinary diversion.

Indiana pouch continent urinary diversion provides patient control over elimination of urine with periods of dryness. This allows emptying of urine from the pouch by catheter at convenient intervals avoiding major metabolic abnormalities with satisfactory renal function. Detubularization of the ascending colon and caecum with tapering of the terminal ileum and tunneled tenial implants of the ureters have resulted continent cutaneous urinary reservoir. In total 10 patients were included and follow-up period was for a period of 6 months to 5 years. One year after surgery overall day and night continence rate was in 70% patients, some leakage at day and night in 30% cases and no patient developed day or night incontinence. The mean capacity of the pouch was 530 ml at 12-18 months. Pouch pressure at full capacity was 16 cm H2O at 18 months. Indiana pouch provides better attention for urinary diversion in developing countries as it is well accepted, economically more suitable and relatively easy to construct, with good results in terms of continence and reduced complications with satisfactory renal function.

Laparoscopic cystotomy for urolith removal in dogs: three case reports / Cistotomia laparoscópica na remoção de urólitos em cães: relato de três casos

The use of laparoscopic surgery for the removal of cystic calculi in three dogs was reported. Three trocars were used, one in the ventral midline (10mm) and the others in the right (10mm) and left (5mm) flanks. The calculi were removed and the bladder was sutured with intracorporeal technique in two layers, a simple continuous pattern and interrupted or continuous Lembert pattern. No postoperative complications were observed. One patient had a recurrence of urolithiasis, attributed to inadequate conservative treatment and to the lack of an appropriate diet. It was submitted to another similar videolaparoscopic cystotomy without complication. The proposed technique is appropriate and an alternative to conventional cystotomy for treatment of canine vesical urolithiasis.

Descreve-se a remoção de cálculos vesicais por cirurgia laparoscópica em três cães utilizando-se três portais (dois de 10mm e um de 5mm) dispostos na linha média ventral e nas paredes abdominais direita e esquerda. Após a remoção das litíases, realizou-se sutura intracorpórea da parede vesical, em padrão contínuo simples, abrangendo as quatro camadas do órgão e em Lembert contínuo ou interrompido, incorporando a serosa e a muscular. Não houve complicações pós-operatórias. Um dos pacientes apresentou recidiva da doença, condição atribuída ao manejo dietético deficiente no pós-operatório. Esse paciente foi novamente submetido à cistotomia laparoscópica similar sem a ocorrência de complicações. A técnica proposta foi adequada e pode ser utilizada como alternativa para cistotomia por celiotomia no tratamento de litíases vesicais em cães.

Long term evaluation of functional and morphological bladder alterations on alloxan-induced diabetes and aging: experimental study in rats / Avaliação funcional e morfológica tardia de alterações na bexiga secundárias ao diabetes induzido por aloxano e no envelhecimento: estudo experimental em ratos

PURPOSE: to evaluate structural and functional effects of Alloxan- induced diabetes and aging on bladder of rats. METHODS: evaluations were performed in three groups: A - 8 weeks of age, B - 44 weeks of age, C - 44 weeks of age with alloxan-induced diabetes. Muscle layer thickness, extracellular matrix fibrosis and collagen were quantified on digital images of bladder samples. Cystometric evaluations before surgical vesical denervation (SVD), included maximum cystometric capacity (MCC), maximum bladder pressure (MBP), bladder contraction frequency (VCF), duration of bladder contraction (DC), threshold pressure (TP) and bladder compliance (BC). After SVD, maximum cystometric capacity (MCC), BC and maximum urethral closing pressure (MUCP) were also measured. RESULTS: Reduced extracellular matrix fibrosis concentration and contraction strength were found in the bladders of group C. Before SVD, bladder compliance was not different between groups. Alterations were observed in MCC after SVD. CONCLUSIONS: We did not notice smooth muscle hypertrophy in Alloxan-induced diabetic rats after 44 weeks. There was alteration in the total and relative amount of fibrosis and collagen. The cystometric studies support the idea that this morphological alterations are important to determine the different bladder functional patterns found in the aging and the Alloxan-induced diabetic animals.

OBJETIVOS: avaliar alterações estruturais e funcionais da bexiga de ratos machos, associadas ao diabetes induzido por aloxano e ao envelhecimento. MÉTODOS: três grupos de animais: A - 8 semanas de idade; B- 44 semanas de idade; C - 44 semanas de idade com diabetes induzido por aloxano, foram avaliados. Realizadas medidas de espessura da camada muscular, fibrose de matriz extracelular e quantidade de colágeno, através de análise de imagem digital dos tecidos. Realizados também testes cistométricos, antes da desnervação vesical cirúrgica (DVC), para avaliar capacidade vesical (CV), intensidade máxima de contração vesical (IMCV) e complacência vesical. Após a DVC, foram avaliadas capacidade vesical após a desnervação (CVAD), complacência vesical (CV) e pressão de perda uretral (PPU). RESULTADOS: não foi observada hipertrofia da camada muscular nas bexigas; houve diminuição da concentração de fibrose da matriz extracelular e diminuição da força contrátil, e aumento da capacidade vesical no grupo C. CONCLUSÕES: a atrofia da camadas muscular da bexiga esta relacionada ao diabetes induzido por aloxano. O envelhecimento, como fenômeno isolado, provoca alterações nos parâmetros funcionais, porém associado ao diabetes, gera alterações na IMCV, CV e CVAD. Existe correlação entre alterações estruturais e funcionais nos animais diabéticos após a desnervação.

[Foreign bodies in the bladder about 4 cases]

Cases of foreign bodies in the bladder are rare and have variable nature. In our society, self-insertion via urethra is the most common cause, especially in young girls in a psychiatric or erotic context. We report 4 observations of bladder stones including foreign bodies in 4 women aged between 18 and 58 years. In 2 cases, it is about an accidental transurethral insertion of a needle and a piece of wood for the purpose of masturbation. In the third case, a bit of urinary catheter, which was put 10 years ago, was found in the bladder. In the last case, it is about an intrauterine contraceptive device which was put 5 years before and then had migrated into the bladder. A suprapubic cystotomy was performed to the 2 first patients. The 2 others had benefited from ballistic lithotripsy with endoscopic extraction of the foreign body. Throughout these observations, we analyse etiological, diagnostic, and therapeutic aspects of this pathology

Avaliação da ação da Aroeira (Schinus terebinthifolius Raddi) na cicatrização de feridas cirúrgicas em bexiga de ratos / Evaluation of the aroreira (Schinus terebinthifolius Raddi) in the healing process of surgical incision in the bladder of rats

OBJETIVO: Avaliar a ação cicatrizante do extrato hidroalcoólico da aroeira em bexigas de ratos. MÉTODOS: Foram utilizados 40 ratos machos da linhagem Wistar, divididos em dois grupos de 20, denominados grupo aroeira (GA) e grupo controle (GC). Todos foram submetidos à incisão abdominal mediana com cistotomia de 1 cm, seguida de cistorrafia em plano único com pontos separados de poliglactina 910 5-0 (Vicryl®). Após este procedimento, nos animais GA injetou-se 100mg por quilo de peso de extrato hidroalcoólico da aroeira na cavidade peritoneal e nos GC injetou-se 1 ml por quilo de peso de solução salina a 0,9 por cento . Cada grupo foi dividido em dois sub-grupos de 10 animais de acordo com a data da morte: sub-grupo A3 e C3, sacrificados no 3° dia pós-operatório e sub-grupo A7 e C7, sacrificados no 7° dia. A parede, a cavidade abdominal e a sutura da bexiga foram avaliadas macroscopicamente. Amostras de tecido da bexiga foram retiradas e analisadas histologicamente, utilizando a coloração de Hematoxilina-Eosina (HE) e tricrômio de Masson. RESULTADOS: Na análise macroscópica observou-se infecção na incisão cirúrgica em três ratos do GC e em um do GA, e aderências peritoneais em 29 ratos do GC controle e 17 no GA. A avaliação microscópica mostrou processo inflamatório agudo mais severo no 3° (p=0,045) e no 7° dia (p=0,002). Evidenciou-se ainda diferença estatística nos parâmetros utilizados para a avaliação histológica da cicatrização da bexiga nas variáveis colagenização (p = 0.001), reepitelização (p = 0,046) e neoformação (p = 0) nos subgrupos GC e GA no 3° dia e na variável neoformação vascular (p=0,001) no subgrupo do 7° dia. CONCLUSÃO: O uso de extrato hidroalcoólico de aroeira mostrou efeito cicatrizante favorável nas cistotomias em ratos.

PURPOSE: To evaluate the hydroalcoholic aroeira extract in the healing process of surgical incisions in the bladder of rats in an experimental comparative study. METHODS: Forty male Wistar rats were used. All of them underwent a median abdominal incision, with an 1cm cistotomy, followed by one plan suture with separated stitches of poliglactine 910 5-0. The animals were then divided into two groups of 20 rats each, and named the aroeira group (GA) and the control group (GC). In the first one, 80 percent hydro-alcoholic plant extract was injected in the peritoneal cavity, in a one dose of 100mg/kg. The second group, a 0.9 percent saline solution was injected in place of aroeira extract. Each group was divided into two subgroups (SGA and SGC) of 10 animals. According to their scheduled death, they were named subgroups SGA3 and SGC3 when killed in the 3th day after surgery and subgroups SGA7 and SGC7 in the 7th day. The abdominal cavity and the bladder suture were macroscopically evaluated. RESULTS: The microscopic analysis of the surgical incision in the bladder was performed by means of the hematoxilin-eosine stain and the trichrome of Masson. The macroscopic analysis showed an infection in the surgical incision in three rats of the SGC group and in one of the SGA, and peritoneal adhesion in the 26 rats belonging nine to SGC and 17 in the SGA. The microscopic evaluation revealed a more severe acute inflammation process in the SGC on the 3th (p=0.045) and in the 7th (0=0.002) days. In the SGA, a more significant colagenization (p=0.001) could be seen, as far as the evidence of vascular neoformation (p=0.002) on the 3th day. Chronic inflammatory reaction (p=0.006) and a more intense vascular neoformation (p=0.001) were observed in the 7th day. CONCLUSION: The hydroalcoholic aroeira extract have a favorable effect in the healing process of cystotomies done in rats.

Ballooning Angioplasty for Residual Stenosis after Cystotomy of the Popliteal Advential Cystic: A Case Report

Adventitial cystic disease (ACD) is an uncommon vascular disease of an unknown origin, and this malady can be suspected in a young, healthy patient who has sudden onset of claudication. We describe here a case of ACD of the right popliteal artery. A 43-year-old male presented with 4 month history of severe right leg claudication. He had no other atherosclerotic predisposing history except for 10 pack years of smoking. On examination, the right femoral pulses were normal, the popliteal artery absent and the dorsalis pedis and posterior tibial artey pulses were decreased. The ankle-brachial pressure index (ABI) was 0.4. Ultrasonography showed a hypoechoic cystic lesion with a well-defined marin along the arterial wall. Computed tomography showed a round hypodense cystic mass with thin enhancing rim and a non-enhancing center in the popliteal fossa. Operatively, the 2.5 cm-sized expanding cyst indented the popliteal artery, which involved half of its diameter with adhesion to the adhesion to the adjacent structures. The artery had no thrombosis and it was a short-segment lesion with luminal patency, but half of the arterial wall was thickened with inflammation. Partial excision of the cyst wall and evacuation of the gelatineous materials was performed. Postoperatively, his symptoms improved somewhat, but ABI was 0.6. On the angiography, there was residual stenosis and contrast pooling. These findings disappeared after balloon angioplasty. he was asymptomatic 6 months later with an ABI >1 in the right side.

Comparison of clinico-histopathologic findings before and after decompression of odontogenic cyst in the jaw

BACKGROUND: For normalization of displaced anatomical structure by large cyst, two-step procedure (decompression and enucleation afterward) has been recommended. However, the histological transformation after cystotomy for decompression was shown frequently in secondary enucleation. Therefore, analyses about effects and histological changes after decompression have been necessary. METHODS: 48 cases diagnosed as large odontogenic cyst in the jaw and treated by decompression and secondary enucleation were retrospectively analyzed in clinical, rediographical, and histological aspects. RESULTS: In dentigerous cyst, decompression was much useful. Impacted permanent teeth were erupted and reduction rate was higher than that of odontogenic keratocyst (OKC) and apical periodontal cyst. In OKC, among the 29 cases, 11 cases showed no-keratosis, proliferation and rete-ridge elongation after decompression. 4 cases showed no-keratosis, only. 7 cases showed orthokeratosis and rete-ridge elongation and 6 cases showed reteridge elongation, only. 1 case had no change. And the recurrence rate for OKCs was 10.3%. For all odontogenic cysts in this study, dysplasia was not found in cystic lining after decompression. CONCLUSIONS: This study implied that decompression for large odontogenic cyst was useful treatment modality because it was conservative treatment and recurrence rate was low although long treatment period was required.

Laser Treatment for Recurrent Secondary Iris Cyst

PURPOSE: To report two cases of recurrent iris cyst, that were treated with argon laser photocoagulation and Nd: YAG laser cystotomy. METHODS: A 56 year-old woman with a history of cataract surgery and trabeculectomy in the right eye 15 months ago was presented with ocular irritation and decreased vision, and a 34 year-old man with a history of ocular trauma in the right eye 10 years ago was presented with photopsia and decreased vision. The recurrent secondary iris cyst was diagnosed in both patients. Argon laser photocoagulation and Nd: YAG laser cystotomy used to coagulate the cysts under the topical anesthesia. After 15 months, recurrent iris cyst developed at the same site of the second patient. The argon laser photocoagulation and Nd: YAG laser cystotomy were repeated. RESULTS: The treatment with argon laser photocoagulation and Nd: YAG laser was effective for the resolution of the recurrent secondary iris cysts.

The Success Rate and Complications of the Primary Endoscopic Urethral Realignment within 3 Days in Male Urethral Injury / 대한비뇨기과학회지

PURPOSE: Attempts have been made to insert a urethral Foley catheter as a primary urethral realignment immediately after a urethral injury. There has been much debate about the time and method of the realignment. The feasibility and complications of early primary endoscopic realignment in a urethral injury were evaluated. MATERIALS AND METHODS: From November 1990 to May 2003, 63 patients with urethral injuries received early endoscopic realignment within 72hrs. The diagnosis was made by retrograde urethrography. Primary realignment was successfully performed for 61 patients; 52 (85.2%) had an anterior urethral injury and 9 (14.8%) a posterior urethral injury. All operations were performed under spinal anesthesia. A cystoscope was inserted through the dilated suprapubic cystotomy and a guide wire passed through the cystoscope, and caught by transurethral foreign body forceps just distal to the injured site. The urethral catheter was removed after pericatheter urethrography, usually on the 14th postoperative day. Patients were retrospectively reviewed for complications, including urethral stricture, urinary incontinence and erectile dysfunction. RESULTS: Of the 63 patients, 61 (96.8%) were successfully treated. The mean operation and catheter indwelling times were 71.8 minute (5-109) and 17.4 days (6-32), respectively. The mean follow-up duration was 423.2 days (94-1432). Urethral strictures were detected in 14 patients (23.0%), who were treated with an internal urethrotomy. Urinary incontinence in 5 patients (8.2%) and erectile dysfunction in 14 patients (23.0%) were the observed complications. CONCLUSIONS: Our results show that immediate endoscopic realignment is a less invasive and more feasible therapy for patients with a urethral injury.
