ABSTRACT

Malignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to minimize the effects of radiation on the tissues surrounding the neoplastic site; despite those strategies, radiotherapy can still result in serious damage to organs and structures, and these injuries accompany patients throughout their lives. One of the most common damages resulting from pelvic radiotherapy is acute proctitis.The diagnosis is confirmed by visualizing the rectal mucosa through rigid or flexible rectosigmoidoscopy and colonoscopy. The objective of the present study was to review the forms of radiation-induced proctopathytherapy, and to evaluate the results of each method to propose a standardization for the treatment of this pathology. Despite the prevalence of radiation-induced proctopathy, there is no definitive standardized treatment strategy so far. The first approach can be tried with local agents, such as mesalazine and formalin. For refractory cases, control can usually be achieved with argon plasma coagulation, hyperbaric oxygen, and radiofrequency ablation therapies. Regarding the study of radiation-induced proctopathy, there is a lack of robust studies with large samples and standardized therapies to be compared. There is a lack of double-blinded, randomized controlled studies to determine a definitive standard treatment algorithm. (AU)

ABSTRACT

Introducción: Varios tratamientos se utilizan para la rectitis actínica hemorrágica, entre ellos corticoides, sucralfato, mezalasina y distintas variantes de cauterización endoscópica, aunque ninguno puede considerarse de elección. En este contexto, la aplicación local de formalina al 4% ha demostrado ser efectiva y segura cuando han fracasado otros tratamientos conservadores. Objetivo: Comunicar nuestra experiencia en el tratamiento de la rectitis actínica sangrante con formalina, describiendo las variantes técnicas de su aplicación y los resultados. Diseño: Observacional retrospectivo. Lugar de aplicación: Hospital público de la Ciudad de Buenos Aires. Pacientes y Método: Se revisaron registros hospitalarios de 10 pacientes (7 mujeres) de edad promedio 61,1±15,6 (rango 28-81) años, con rectitis sangrante posterior a radioterapia pelviana. La dosis osciló entre 7400 y 8000 cGy y el sangrado comenzó en promedio 7,2±3,1 (rango 2-12) meses luego de finalizada la misma. Todos los pacientes presentaban anemia y habían recibido uno o más tratamientos conservadores previos sin respuesta, tres de los cuales habían requerido transfusiones. La terapia con formalina se realizó con dos modalidades: Grupo I: hisopo embebido en formalina al 4% a ph 7 puesto en contacto con la superficie sangrante durante 1-2 minutos. Grupo II: instilación de un volumen de 100-200 ml, en bolos de 30-40 ml por área sangrante, mantenidos en contacto durante 30-60 segundos con posterior aspiración y lavado con solución fisiológica entre los bolos y al final del procedimiento. La respuesta fue considerada completa cuando el sangrado cesó por completo o sólo hubo esporádicas y escasas pérdidas hemáticas, que no requirieron ningún tratamiento. La respuesta parcial se definió como la mejoría en frecuencia y magnitud del sangrado que no requirió otra terapia agresiva. Resultados: Se trataron 10 pacientes (Grupo I: 8 y Grupo II: 2)... (TRUNCADO)...


Background: Several treatments are used for radiation-induced hemorrhagic proctitis, among these corticosteroids, sucralfate, mezalasina, and cauterization endoscopic variants, but none can be considered of choice. With varying results are described. In this context, the local application of 4% formalin has proven to be effective and safe when other conservative treatments have failed. Objective: To report on our experience in the treatment of radiation-induced hemorrhagic proctitis, describing the technical variants of its implementation and results. Design: Observational retrospective study. Setting: Public Hospital of the City of Buenos Aires. Patients and Methods: Hospital records of 10 patients (7 women), average age 61.1 ± 15.6 (range 28-81) years, with radiation-induced hemorrhagic proctitis after pelvic radiotherapy were reviewed. The doses ranged from 7400 to 8000 cGy and the bleeding started on average 7.2 ± 3.1 (range 2-12) months after it ended. All patients had anemia and had received one or more previous conservative treatments with no response, and three of them had required transfusions. Formalin therapy was performed in two ways: Group I: swab with 4% formalin at pH 7 in contact with the bleeding surface for 1-2 minutes. Group II: instillation of a volume of 100-200 ml, in 30-40 ml bolus by bleeding area, maintained in contact with that area for 30-60 seconds, with subsequent aspiration and washing with saline solution between the boluses and the end of the procedure. Treatment response was considered complete when the bleeding stopped completely or there was sporadic and limited blood loss not merequiring any treatment. Partial response was defined as improvement in the frequency and magnitude of bleeding not requiring other aggressive therapy... (TRUNCATED)...

ABSTRACT

PURPOSE: To investigate the effects of placement of the absorbable packing material Nasopore at the anastomosis site of newly formed mucosal flaps on postoperative re-bleeding, discomfort, and on the success rate of dacryocystorhinostomy (DCR). METHODS: A review of the medical records of patients with primary acquired nasolacrimal duct obstruction that underwent external or endonasal DCR by a single surgeon was performed. The degree of re-bleeding, discomfort, and postoperative results, including anatomical success, functional success and postoperative nasal findings such as granulation, synechiae, and membrane formation were compared in patients whose anastomosis site was packed with either Nasopore or Merocel, a non-absorbable packing material. RESULTS: A total of 77 patients (101 eyes) were included. Of the 101 eyes, 30 were packed with Nasopore, while 71 were packed with Merocel. The Nasopore group showed significantly better results than the Merocel group in the degree of re-bleeding and the level of patient discomfort (p = 0.000, 0.039, respectively; Pearson's chi-square test), whereas there were no statistically significant differences between the two groups in postoperative anatomical and functional success (p > 0.05). CONCLUSIONS: Nasopore significantly reduced postoperative nasal re-bleeding and patient discomfort during the early post-surgical period, but failed to show an effect on the postoperative anatomical and functional success of DCR.

ABSTRACT

Radiotherapy is an important discovery as to the treatment of pelvic tumors. Proctitis is frequently observed nowadays, and can be divided into acute and chronic. Treatment with 4% formalin solutions has been used with positive results in literature. Objective: To evaluate the effectiveness and morbidity rates related to the use of 4%formalin in hemorrhagic chronic actinic proctitis. Methods: We evaluated the sigmoidoscopy records and reports of 11 patients with chronic hemorrhagic actinic proctitis from February to December 2010, coming from the Serbian colorectal University Hospital of the State of Sergipe. Results: The study was comprised of 11 patients (36.36% were females and 63.63% were males). Mean age was 67.7 years. Mean time between the end of radiotherapy and the onset of symptoms was 6.6 months. The treatment was completely effective in 27.27% of the cases, and reduced rectal bleeding in 100% of patients. The following main complications were observed: chills (9%), tenesmus (18.18%) and mild stenosis (9%). Conclusions: The 4%formalin solution has fewer side effects, and its administration is very inexpensive. The treatment is effective and reduces bleeding in almost 100% of cases. (AU)

ABSTRACT

Background: Hemorrhagic radiation rectitis occurs in 15 percent of patients subjected to pelvic irradiation. One of the treatment alternatives is the topical application of 4 percent formaldehyde. Aim: To report the results of the use of topical formaldehyde in radiation rectitis. Material and Methods: Twenty patients aged 36 to 80 years (13 women) with hemorrhagic radiation rectitis were prospectively recruited. Fistula or stenosis was discarded endoscopically. Formaldehyde was applied in the operating room or at the outpatient clinic. Results: Fifteen patients required repeated transfusions. The application was performed in the operating room in five patients. Bleeding stopped in three patients with one application, in 12 patients with two applications and in four, with three applications. In one patient, bleeding did not stop after the first application and had a sigmoid perforation; therefore no further application was attempted. One patient had a severe proctitis after the procedure, which subsided with symptomatic treatment after 15 days. Conclusions: Topical formaldehyde application for hemorrhagic rectitis is effective to stop bleeding but has complications in 10 percent of patients.


Introducción: La rectitis actínica hemorrágica es una complicación que se presenta en el 15 por ciento de los pacientes sometidos a radioterapia por una neoplasia pélvica. Existen distintas alternativas para su tratamiento, entre las que se cuenta la aplicación de formalina al 4 por ciento. Presentamos los resultados del tratamiento de esta complicación en una serie prospectiva no aleatoria. Material y Método: Desde marzo de 2004 a mayo de 2007 se reclutaron en forma prospectiva todos los pacientes tratados por una rectitis actínica hemorrágica en nuestro servicio. En todos los pacientes se descartó una estenosis o fístula por endoscopia flexible. Los pacientes fueron sometidos a aplicación de formalina en pabellón o ambulatoria según la evaluación del tratante. Resultados: La serie corresponde a 20 pacientes, 13 mujeres, con un promedio de edad de 61 años (36-80), 15 requerían transfusiones a repetición. La indicación de radioterapia fue por un cáncer cérvico uterino en 9 casos, de próstata en 7 casos y endometrio en 4. El promedio de sesiones necesarias para controlar el sangrado fue de 2 (1-3); en 5 pacientes la aplicación se realizó en pabellón. Tres pacientes mejoraron con una aplicación, 12 pacientes con 2 aplicaciones y 4 con 3 procedimientos. Un paciente continúa sangrado después de un procedimiento, pero presenta una perforación de sigmoides en terreno neoplásico y no se intentó una segunda sesión, por lo que se considera un fracaso del procedimiento. Además un paciente presentó una proctitis intensa que cedió con tratamiento sintomático en 15 días, con lo que la morbilidad del procedimiento alcanza a un 10 por ciento. El éxito acumulado es de un 95 por ciento de los casos, con detención del sangrado, sin necesidad de transfusiones. Conclusión: Estimamos que el tratamiento con formalina al 4 por ciento es un procedimiento seguro para el tratamiento de la rectitis actínica hemorrágica, con buenos resultados en la gran mayoría de los pacientes ...

ABSTRACT

A retite actínica hemorrágica é um quadro grave que pode ocorrer em qualquer paciente submetido à radioterapia pélvica, por vezes, sendo necessária terapia transfusional e internação hospitalar. A abordagem terapêutica ainda é bastante controversa. Tanto para o tratamento inicial como para casos refratários, uma das opções é a aplicação de formalina. Este método é barato, facilmente disponível, de simples execução e eficaz no controle da hemorragia. Os autores relatam dois casos de retite actínica hemorrágica de pacientes tratados com instilação de formalina endoluminal, e sua eficácia terapêutica e complicações são discutidas.


The radiation-induced hemorrhagic proctitis is a serious condition that can occur in any patient undergoing pelvic radiotherapy, sometimes being required hospitalization and transfusion therapy. The therapeutic approach is still very controversial. Both for the initial treatment and for refractory cases, one option is formalin application. This method is cheap, easily available, simple to perform, and effective in controlling bleeding. The authors report two cases of radiation-induced hemorrhagic proctitis treated with endoluminal instillation of formalin, and they discuss its therapeutic efficacy and complications.

ABSTRACT

The purpose of this study was to evaluate the influence of coronal leakage on the healing of dogs' periapical tissues after root canal filling, post space preparation and protection or not with a temporary sealer plug. Forty root canals of dogs' teeth were instrumented and filled by the lateral condensation technique with gutta-percha points and Endomethasone or CRCS sealers. After post space preparation, the remaining filling material was protected or not with a plug of temporary Coltosol sealer and exposed to the oral environment for 90 days. Thereafter, the animals were sacrificed and the specimens were removed and prepared for histomorphological and histobacteriological analysis. The findings revealed 35 percent of microbial leakage in the groups without plugs and 15 percent of leakage in the groups with plugs. Statistical analysis showed that the use of a Coltosol plug improved significantly the histomorphological results regardless of the type of root canal sealer (p=0.05) and that CRCS and Endomethasone sealers showed similar results (p>0.05).


O propósito deste trabalho foi avaliar a influência da infiltração coronária no reparo dos tecidos periapicais após obturação dos canais radiculares, preparo para pino e proteção ou não de um "plug" de cimento temporário. Quarenta canais de dentes de cães foram instrumentados e obturados pela técnica da condensação lateral ativa com cones de guta-percha e os cimentos Endomethasone e CRCS. Após preparo para pino os remanescentes do material obturador foram protegidos ou não com um "plug" do cimento temporário Coltosol e expostos ao meio oral por 90 dias. Decorrido este período, os animais foram mortos e os espécimes foram removidos e preparados para análises histomorfológica e histobacteriológica. Foi observado 35 por cento de casos de infiltração bacteriana nos grupos sem "plug" e 15 por cento nos grupos com "plug". Concluiu-se estatisticamente que o "plug" de Coltosol foi eficiente no controle da infiltração coronária de microorganismos (p=0,05), e que os cimentos CRCS e Endomethasone apresentaram resultados semelhantes (p>0,05).

ABSTRACT

Os enxertos de cartilagem constituem-se em boa opção técnica para aprimoramento das rinoplastias. Procura-se um material para sua fixação que seja de simples manuseio, e que provoque mínima reação tecidual. OBJETIVO: Comparar o uso do butil-2-cianoacrilato, mistura gelatina-resorcina-formaldeído (GRF) e sutura na estabilização de enxertos de cartilagem em coelhos. FORMA DE ESTUDO: Experimental. MATERIAL E MÉTODO: Utilizaram-se 15 coelhos adultos da raça Nova Zelândia machos, de cujas orelhas foram ressecados 6 enxertos de cartilagem, fixados no periósteo da calvária e unidos dois a dois com sutura, GRF e cianoacrilato. Após 2, 6 e 12 semanas, grupos de 5 coelhos foram sacrificados e realizou-se avaliação da distância de deslocamento do enxerto e análise histológica do processo inflamatório tecidual e da adesão/deformidade das cartilagens. RESULTADOS: Houve deslocamento menor nas fixadas com GRF do que com cianoacrilato e sutura. O processo inflamatório foi maior nos animais de 2 semanas, decaindo até restar pequeno grau de fibrose em 12 semanas, de modo semelhante nas 3 fixações. Não houve descolamento nem deformidade em nenhuma dupla de cartilagens fixada com sutura e o maior número de cartilagens descoladas e deformadas se deu com o cianoacrilato. O número de cartilagens deformadas foi diretamente proporcional ao número de descoladas. Os dados foram significativos estatisticamente (p<0,05). CONCLUSÃO: A mistura gelatina-resorcina-formaldeído mostrou ser um método de estabilização de enxertos de cartilagem em coelhos superior ao butil-2-cianoacrilato em todas as fixações, e à sutura na fixação cartilagem-osso.


Cartilage grafting is an interesting option for rinoplasties refinements. AIM: to compare butyl-2-cyanocrylate, compound gelatin-resorcin-formaldeyide (GRF) and suture control to determine the efficacy of these tissue glue preparations in securing grafted cartilage. STUDY DESIGN: Experimental. METHODS: Fifteen male adult New Zealand rabbits were submitted to a surgical procedure to harvest 6 auricular cartilage grafts from each animal. 2 of these grafts in each animal were glued together with butyl-2-cyanocrylate, 2 with compound gelatin-resorcin-formaldehyde and 2 sewn together with nylon suture. These sandwich grafts were then glued or sewn to the periosteum of the calvaria. After 2, 6 and 12 weeks, groups of 5 animals were sacrificed and histological analysis for inflammation was performed. Cartilage graft migration, adhesion and deformities of the grafts were also evaluated. RESULTS: there was less migration of the cartilages glued with GRF than with cyanoacrylate and suture. There was no statistical difference between the 3 materials of graft stabilization in relation to the inflammatory reaction in all evaluated periods. There wasn't detachment neither deformity in the cartilage sandwiches sewed with suture. The majority of detachment and deformed cartilages were found among those glued with cyanoacrylate. The number of deformed cartilages was directly related to the number of detached cartilages. The data were statistically significant (p< 0.05). CONCLUSION: the compound gelatin-resorcin-formaldehyde revealed to be a stabilization material for cartilage grafts in rabbits better than butyl-2-cyanoacrylate. The compound gelatin-resorcin-formaldeyide was also better than the suture when comparing it's fixation to the periosteum.

ABSTRACT

Com o objetivo de otimizar a técnica de imunoistoquímica para detecção de herpesvírus bovino tipo 5 (BHV-5) em tecidos do sistema nervoso central fixado em formaldeído, foram avaliados diferentes métodos de digestão enzimática, diferentes anticorpos e reagentes para bloqueio de reações inespecíficas. As reações apresentaram a máxima intensidade de coloração específica e a quantidade mínima de coloração de fundo quando foram usadas protease de Streptomyces griseus (0,1%) ou proteinase K de Tritirachium album limber (0,05%), mediante incubação durante 15 minutos a 37ºC. Entre os anticorpos monoclonais analisados, dois foram capazes de detectar BHV-5. As reações inespecíficas foram bloqueadas mais efetivamente pela incubação do tecido com caseína (0,5%), durante cinco minutos, ou leite em pó (2,5%), durante 60 minutos, ou soro eqüino (2,5%), durante 60 minutos. Com a técnica otimizada foi possível a detecção de BHV-5 em material de arquivo.

ABSTRACT

Twenty one posterior teeth were selected at random from patients visiting outpatient Department of Punjab Govt. Dental College and Hospital, Amritsar. Out of twenty one treated teeth, seventeen had definite radiolucent area at periapex, three were non vital with no periapical radiolucent area and one tooth was vital with pulp exposure. All the teeth were treated with resinifying therapy. The treated teeth were examined after 3 months, 6 months and 9 months as regards pain on percussion, swelling and/or sinus formation. The teeth were radiographed on each follow up and the decrease/increase in radiolucency at the periapex were noted. Clinically all the treated teeth responded normal except for one which showed sinus formation after three months period of observation. This tooth was, however, retreated. Radiologically, the success rate after 9 months of observations was 84.1%. However, mean decrease in radiolucency was 2.1 mm after 3 months, 4.0 after 6 months and 5.8 after 9 months. Resinifying therapy is strongly advocated for posterior teeth with large periapical areas and also for vital teeth with pulp exposure where root canal therapy can be completed in single visit. Furthermore, the mechanism, indications and contraindication of this therapy are also discussed.

ABSTRACT

En los últimos diez años, tres niños con cuadros oncológicos en tratamiento quimioterápico, que incluía ciclosfosfamida, presentaron hematuria masiva con anemia severa, resistente a tratamiento generales y locales, su gravedad llegó a plantear la cistectomía radical. La instilación intravesical de formalina al 2 por ciento detuvo las hemorragias

ABSTRACT

Se presentan 91 casos de quistes hepáticos comunicados a la vía biliar, de 435 casos de hidatidosis hepática intervenidos. La hidatidosis es una enfermedad endémica de diversos países de la región Mediterránea, Sudamérica y el Pacífico, y el hígado es el principal órgano afectado. En su evolución la apertura hacia la vía biliar es la complicación más frecuente. Las operaciones radicales sobre el quiste proporcionan los mejores resultados con menor morbimortalidad. El tratamiento del sistema biliar debe asegurar la evacuación completa de los componentes del parásito y prevenir complicaciones especialmente relacionadas con la fuga biliar. La fístula biliar y el absceso subfrénico son las complicaciones postoperatorias más frecuentes. La esfinteroplastia y coledocotomía con cierre primario son un procedimiento de elección

ABSTRACT

Este estudo avaliou a eficácia de um dentifrício contendo formaldeído e carbonato de cálcio. Os dentes com hipersensibilidade dentinária foram divididos aleatoriamente em dois grupos: grupo 1 (com intervalos de retorno para avaliaçäo clínica a cada três dias) e grupo 2 (com intervalos de retorno a cada sete dias). Para o estímulo da dor, empregou-se jato de ar no colo dos dentes afetados. Demonstrou-se que o dentifrício avaliado reduz a dor da hipersensibilidade dentinária de grau 1, principalmente quando em uso mais prolongado (Grupo 2). Em contraposiçäo, efeitos indesejáveis como ardência e gosto ruim na boca ao uso do dentifrício foram encontrados em alguns pacientes

ABSTRACT

Os autores mostraram em estudo experimental anastomoses intestinais feitas em cao com objetivo de testar o uso de adesivo à base de resorcina com formaldeido 3 por cento e glutaraldeído 25 por cento (Colagel).R Para isto utilizaram 6 caes mestiços, 3 machos e três fêmeas, com peso médio de 15 kg. Eram confeccionadas, em cada cao, duas secçoes transversas no intestino delgado, distante uma da outra 40 cm e reconstituiçao término-terminal. A primeira anastomose era feita com sutura em plano único extra-mucoso e pontos separados de fio monofilamentar de nylon 5-0 e a segunda anastomose era feita por técnica de telescopagem utilizando-se o adesivo em teste. Todos os animais morreram antes da data prevista para o sacrifício, num intervalo de tempo de 24 a 72 horas. A necrópsia revelou integridade da primeira anastomose com deiscência parcial ou total da segunda. Concluem nao ser este adesivo biológico útil em anastomoses intestinais pela técnica proposta.

ABSTRACT

Se presenta una actualización bibliográfica sobre dos nuevos métodos utilizados en el tratamiento de la hiperestesia dentaria: la aplicación de flúor por ionoforesis y la electrocoagulación con solución de formalina al 10 %. Se analizan los mecanismos de acción, transporte de iones, así como las conclusiones de diferentes investigaciones clínicas y de laboratorio, donde se demuestra la gran efectividad de ambos métodos en el tratamiento de los cuellos sensibles
