Trombose de seio sigmoide secundária a fístula liquórica espontânea para osso temporal: um relato de caso / Sigmoid sinus thrombosis secondary to spontaneous temporal bone cerebrospinal fluid fistula: a case report

A fístula liquórica para o osso temporal constitui um evento raro que decorre da comunicação anormal entre o espaço subaracnóideo e as células da mastoide, permitindo que o líquido cefalorraquidiano flua para as porções pneumatizadas do osso temporal. Tem como consequência a hipotensão intracraniana espontânea, caracterizada por perda de líquor e pela manifestação clínica de cefaleia ortostática. Acredita-se que a hipotensão intracraniana espontânea crie condições hemodinâmicas favoráveis à ocorrência de trombose venosa cerebral, uma desordem potencialmente fatal e de difícil diagnóstico, visto a inespecificidade de sinais clínicos e sintomas. Dessa forma, é pertinente atentar para a possibilidade de trombose venosa cerebral em pacientes com fístulas liquóricas, especialmente quando houver mudança do padrão da cefaleia, que passa de ortostática a intensa e contínua.

Temporal bone cerebrospinal fluid fistula is a rare event that results from abnormal communication between the subarachnoid space and the mastoid cells, allowing the cerebrospinal fluid to flow into the pneumatized portions of the temporal bone. It leads to spontaneous intracranial hypotension, characterized by loss of cerebrospinal fluid and orthostatic headache as a clinical manifestation. Spontaneous intracranial hypotension is believed to create favorable hemodynamic conditions to the occurrence of cerebral venous thrombosis, a potentially fatal disorder of difficult diagnosis given the nonspecific clinical signs and symptoms. Therefore, it is pertinent to consider the possibility of cerebral venous thrombosis in patients with cerebrospinal fluid fistulas, especially when there is a modification in the headache pattern from orthostatic to intense and continuous pain.

Tiroiditis aguda supurada en una paciente con fístula del seno piriforme: presentación de un caso / Acute suppurative thyroiditis in a patient with a piriform sinus fistula: A case report

La tiroiditis aguda supurada es una entidad poco frecuente en pediatría; de origen infeccioso, cuya etiología más frecuente es bacteriana. Su presentación típica en niños es la aparición de una tumoración en la cara anterior del cuello, con signos de flogosis, dolorosa, caliente y eritematosa, que excursiona con la deglución, y puede o no estar acompañada de fiebre, disfagia o disfonía. En niños, las anomalías congénitas, principalmente la fístula del seno piriforme, predisponen a la infección de la glándula, por lo que es importante la resolución quirúrgica del defecto anatómico para prevenir las recurrencias. El diagnóstico rápido, basado en la clínica y los estudios por imágenes, es importante para comenzar en forma temprana con un tratamiento antibiótico adecuado.Se presenta una paciente de 3 años, previamente sana, con tumoración cervical izquierda dolorosa y asociada a fiebre. Durante la internación, se arribó al diagnóstico de tiroiditis aguda supurada secundaria a fístula de seno piriforme.

Acute suppurative thyroiditis is an infectious disease, uncommon in children, caused by various microorganisms, being bacteria the most frequently involved. The typical presentation includes the appearance of a tumor in combination with signs of swelling in the anterior aspect of the neck, which is painful on palpation and is associated with warmth and erythema. It usually moves with swallowing and the patient can suffer fever, dysphagia or dhysfonia. In children, congenital anomalies can lead to the gland's infection, and the surgical excision of them is important to prevent recurrency. A quick diagnosis, based on clinical manifestations and imaging studies, is necessary to install an adequate antibiotic treatment. We present the case of a 3-year-old patient, who was previously healthy, with a painful left cervical tumor associated with fever. During the hospitalization, we reached the diagnosis of acute suppurative thyroiditis caused by an underlying pyriform sinus fistula

Does Mean Platelet Volume Decrease in the presence of Coronary Artery Fistula? / O Volume Médio Plaquetário Diminui na Presença de Fístula da Artéria Coronária?

Abstract Background: Coronary artery fistula (CAF) is an abnormal connection that links a coronary artery to a cardiac chamber or another major blood vessel. Several studies have shown the association between mean platelet volume (MPV) and cardiovascular diseases. In the literature, there is no previous study about the association between hematologic parameters and congenital CAF. For this reason, we aimed to investigate the association of MPV with CAF. Methods: 70 patients with normal coronary arteries and 50 with coronary artery fistulas were included. Routine blood and biochemical parameters were measured before the arteriography. Differences between groups for continuous variables were analyzed with t- test or Mann-Whitney test. P values < 0.05 were considered significant. Regression analysis was used to find independent predictors of CAF. Results: Baseline patient demographics, including age and clinical risk factors, were similar between the groups. Compared to the control group, median (IQR) High-density lipoprotein cholesterol (HDL) levels were significantly higher (p=0.04) and MPV levels were significantly lower in the CAF group (8.84 ± 1.71fL vs. 10.43 ± 1.34, p < 0.001). In the multivariate analysis, only MPV was a significant predictor of CAF (p < 0.001, 95% CI for OR: 0.438 (0.306-0.629). A negative correlation was found between MPV and fistulae in Pearson's correlation test (r: -0.454, p < 0.001). An MPV level of < 9,6 fL showed sensitivity, specificity, positive predictive value and negative predictive value of 80%, 68%, 71% and 78% respectively (AUC = 0.766, 95% CI, 0.678-0.854) for the prediction of CAF. Conclusion: The present study suggests that MPV may decrease in patients with CAF.

Resumo Fundamento: A fístula da artéria coronária (FAC) é uma conexão anormal que liga a artéria coronária a uma câmara cardíaca ou outro importante vaso sanguíneo. Vários estudos mostraram a associação entre o volume plaquetário médio (VPM) e as doenças cardiovasculares. Na literatura, não há estudo prévio sobre a associação entre os parâmetros hematológicos e a FAC congênita. Por essa razão, nosso objetivo foi investigar a relação do VPM com a FAC. Métodos: Foram incluídos 70 pacientes com artérias coronárias normais e 50 com fístulas de artérias coronárias. Os parâmetros sanguíneos e bioquímicos de rotina foram medidos antes da arteriografia. As diferenças entre os grupos para as variáveis contínuas foram analisadas com o teste t ou teste de Mann-Whitney. Valores de p < 0,05 foram considerados significativos. A análise de regressão foi utilizada para encontrar preditores independentes de FAC. Resultados: Os dados demográficos basais dos pacientes, incluindo idade e fatores de risco clínicos, foram semelhantes entre os grupos. Comparados à mediana do grupo controle (IIQ), os níveis de HDL-colesterol foram significativamente mais altos (p = 0,04) e os níveis de VPM foram significativamente mais baixos no grupo FAC (8,84 ± 1,71fL vs. 10,43 ± 1,34, p < 0,001). Na análise multivariada, apenas o VPM foi um preditor significativo de FAC (p<0,001, IC 95% para OR: 0,438 (0,306-0,629)). Foi encontrada uma correlação negativa entre o VPM e fístulas no teste de correlação de Pearson (r: -0,454, p < 0,001). Um nível de VPM < 9,6 fL apresentou sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo de 80%, 68%, 71% e 78%, respectivamente (AUC = 0,766, IC 95%, 0,678-0,854) para a previsão de FAC. Conclusão: O presente estudo sugere que o VPM pode diminuir no paciente com FAC.

Oiigen anomalo de la arteria coronaiia derecha de la arteiia pulmonar en un lactante con soplo cardiaco: A proposito de un caso / Anomalous origin of the right coronary artery from the pulmonary artery in an infant with a heart murmur: Case report

El origen anómalo de la arteria coronaria derecha de la arteria pulmonar es una entidad rara con una incidencia del 0,002 % y potencialmente grave, que puede causar muerte súbita. El diagnóstico frecuentemente es incidental, secundario a evaluaciones por soplos cardíacos a diferencia del origen anómalo de la arteria coronaria izquierda de la arteria pulmonar, reconocido por presentar isquemia miocárdica e insuficiencia cardíaca. Se reporta el caso de una niña de 6 meses evaluada por un soplo y derivada por sospecha de fístula coronaria. La evaluación mediante ecocardiograma doppler color, cateterismo cardíaco y angiotomografía mostró la presencia de una comunicación interauricular ostium secundum pequeña y origen anómalo de la arteria coronaria derecha de la arteria pulmonar. A los 11 meses, se realizó una cirugía de reimplante de la arteria coronaria derecha en la arteria aorta y el cierre de la comunicación interauricular.

The anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare entity that has an incidence of 0.002 % and can potentially cause sudden death. Unlike to the anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), usually presented with myocardial ischemia and heart failure; the diagnosis of ARCAPA is often incidental during evaluation of a heart murmur. We report a case of a 6 months old female patient referred to us with a cardiac murmur and a suspicion of coronary fistula. For a proper diagnostic assessment an echocardiogram, a computed tomography angiography and a cardiac catheterization were requested. A small ostium secundum-type atrial septal defect (ASD) and an ARCAPA were revealed. At 11 months old, the patient was scheduled for corrective cardiovascular surgery. The aim of this report is to describe a low incidence and potentially fatal disease.

Factores de riesgo en la aparición de fístula faringocutánea / Risk factors in the apparition of pharyngocutaneous fistula

RESUMEN Introducción: la fístula faringocutánea es la complicación postoperatoria más frecuente de la laringectomía total. Incrementa la morbimortalidad, demora la administración del tratamiento oncológico y repercute en la esfera psicológica del paciente. Objetivo: conocer el comportamiento de la fístula faringocutánea en pacientes con laringectomía total. Materiales y métodos: se realizó un estudio observacional, descriptivo, retrosprospectivo en el Hospital Universitario "Comandante Faustino Pérez", en el período comprendido entre enero 2010 a diciembre 2015. El universo lo constituyó 143 pacientes laringectomizados. Se estudiaron las variables: edad, sexo, estado nutricional previo a la cirugía, estadio del tumor, radiaciones, traqueostomía; manejo del cuello, previo a la cirugía, y evolución de la fístula. Resultados: presentó fístula postoperatoria el 28 %, predominando el sexo masculino, en un 92.3 %; y los normopesos en un 56,6 %. Se encontraban en estadio IV, el 70 %. Fueron irradiados 72,5 % y se les practicó traqueostomía, previa a la cirugía, al 95 % de los pacientes. Vaciamiento cervical se realizó al 37,5 %. En el 70 % de los pacientes, la fístula apareció entre los 8 y 14 días. Conclusiones: la incidencia de la fístula faringocutánea es mayor en el sexo masculino entre los 60-69 años. La mayor incidencia ocurrió en el año 2015. El estadio avanzado del tumor, la presencia de traqueostomía, el estado nutricional e irradiación previa, fueron los factores que más incidieron en la aparición de fístula faringocutánea. En la mayoría de los pacientes el cierre fue espontáneo con buena su evolución (AU).

ABSTRACT Introduction: pharyngocutaneous fistula is the most frequent post-surgery complication of the total laryngectomy. It increases morbimortality, delays the administration of the oncological treatment and rebounds in the patient's psychological sphere. Objective: to know the behavior of the pharyngocutaneous fistula in patients with total laryngectomy. Materials and methods: a retrospective, descriptive, observational study was carried out in the University Hospital "Comandante Faustino Pérez", in the period from January 2010 until December 2015. The universe were 143 patients who undergone a laryngectomy. The studied variables were age, sex, nutritional status before the surgery, tumor stage, radiations, tracheotomy, neck management before surgery, and fistula evolution. Results: 28 % of the patients presented post-surgery fistula, predominantly among males (92.3 %). Normal weight patients were 56.6 %; 70 % were in the IV stage. 72.5 % of the patients were irradiated and 95 % undergone tracheotomy before the surgery. 37.5 % of them undergone cervical resection. In 70 % of the patients, the fistula appeared after 8-14 days. Conclusions: the incidence of the pharyngocutaneous fistula is higher in the male sex and the 60-69 years age-group. The highest incidence occurred in 2015. The advanced stage of the tumor, the presence of tracheotomy, the nutritional status and previous irradiation were the factors that had more incidences on pharyngocutaneous fistulae. The closure of the fistula was spontaneous in most of the patients, with a good evolution (AU).

Vesicouterine fistula (Youssef syndrome): case report and literature review / Fístula vesico-uterina (síndrome de Youssef): descrição de caso e revisão da literatura

Abstract Objective To describe a case of vesicouterine fistula and to review the literature related to this condition. Methods For the review, we accessed the MEDLINE, BIREME and LILACS databases; the references of the searched articles were also reviewed. Results A 38-year-old woman, in the 1st day after her 3rd cesarean, presented heavy hematuria, which was considered secondary to a difficult dissection of the bladder. A total of 6 months after delivery, she failed to resume her regular menstrual cycles and presented cyclic menouria and amenorrhea. At this time, she had two episodes of urethral obstruction by blood clots. She remained without a correct diagnosis until about two years postdelivery, when a vesicouterine fistula was confirmed through cystoscopy. A surgical correction through open abdominal route, coupled with hysterectomy, was performed. After the surgery, the symptoms disappeared. The review showed a tendency of change in the relative frequency of the different types of genitourinary fistulae. Vesicovaginal fistulae, usually caused by inadequate care during labor, are becoming less frequent than those secondary tomedical procedures, such as vesicouterine fistulae. The most common cause of this latter kind of fistula is cesarean section, especially repeated cesarean sections. The diagnosis is confirmed through one or more imaging exams, or through cystoscopy. The most common treatment is surgical, and the routes are: open abdominal, laparoscopic, vaginal or robotic. There are some reports of success with the conservative treatment. Conclusion Vesicouterine fistulae are becoming more common because of the increase in the performance of cesarean sections, and the condition must be considered a possible complication thereof.

Resumo Objetivo Apresentar um caso de fístula vesico-uterina e realizar revisão da literatura sobre esta condição. Métodos Revisão realizada consultando-se as bases MEDLINE, BIREME e LILACS, além das referências dos artigos consultados. Resultados Uma mulher de 38 anos, após sua terceira cesárea, no puerpério imediato, apresentou hematúria importante, que foi atribuída a uma dificuldade na dissecção da bexiga durante o procedimento. Seis meses pós-parto, emvez de retomar os ciclos menstruais regulares, apresentou menúria cíclica e amenorreia (síndrome de Youssef). A paciente chegou a apresentar obstrução uretral por coágulos, e permaneceu sem diagnóstico correto até cerca de anos pós-parto, quando este foi feito por cistoscopia. Ela foi então submetida a correção cirúrgica por via abdominal, associada a uma histerectomia, com desaparecimento dos sintomas. A revisão mostrou que tem havido mudança na frequência dos vários tipos de fístulas urogenitais. As fístulas vesicovaginais, normalmente secundárias à má assistência durante o parto, têm sido mais raras, enquanto aquelas secundárias a procedimentos médicos, como as vesicouterinas, têm sido mais frequentes. A causa mais comum deste tipo de fístula é a cesárea, especialmente a de repetição. A apresentação pode ser de amenorreia e menúria e/ou perda urinária. O diagnóstico é feito por um ou maismétodos de imagem ou cistoscopia. O tratamento mais comum é cirúrgico, por via abdominal aberta, laparoscópica, transvaginal ou robótica. Existem relatos de cura com tratamento conservador. Conclusão As fístulas vesicouterinas têm sido mais comuns devido ao aumento da proporção de cesáreas. Deve-se ter em mente a possibilidade deste diagnóstico e considerá-las uma das possíveis complicações da cesárea.

Fístulas del seno piriforme congénitas: reporte de 4 casos y revisión de la literatura / Congenital pyriform sinus fistula: report of 4 cases and review of the literature

Resumen Introducción: Las fístulas del seno piriforme, originadas desde el tercer o cuarto arco branquial, son entidades poco frecuentes. Se pueden presentar como aumento de volumen cervical, fístula cervical, absceso cervical, tiroiditis abscedada y/o disfonía. Objetivo: Reportar 4 casos tratados en nuestro hospital y revisión de la literatura. Discusión: Frente a un cuadro clínico compatible, se debe realizar estudio endos- cópico y de imágenes. El manejo quirúrgico sigue siendo el de mejores resultados, pero se han desarrollado terapias endoscópicas y combinaciones de estas con buenos resultados. Conclusión: El diagnóstico requiere un alto índice de sospecha clínica. La cirugía abierta se mantiene como el gold standard, sin embargo, en población pediátrica estaría indicada la resolución endoscópica debido a la alta morbilidad de la cirugía tradicional.

Introduction: Pyriform sinus fistula is a rare cervical branchial anomaly derived from the third and fourth branchial arch. Pyriform sinus fistula should be considered in children presenting enlarged neck mass, fistula, abscess, thyroid infection and/or dysphonia. Objective: We here report 4 cases treated in Hospital Clínico Universidad de Chile and review of the current literature on pyriform sinus fistula. Discussion: When clinical presentation is compatible with pyriform sinus fistula, endoscopic and imaging techniques are required. Surgical outcomes are better, although endoscopic therapies and combination of both surgery and endoscopy have also reported good outcomes. Conclusion: Diagnosis is made based on signs and symptoms and a high index of clinical suspicion. Open surgery is gold standard, however in pediatric population endoscopic resolution should be considered to reduce the high morbidity of traditional surgery.

Oclusão de fístula oronasal em gato com uso somente de resina acrílica autopolimerizável / Oronasal fistula occlusion in cat using only acrylic resin / Oclusión de fístula oronasal en gato con uso sólo de resina acrílica autopolimerizável

A fenda palatina é uma comunicação congênita ou adquirida entre as cavidades oral e nasal, permitindo a passagem de alimentos e líquidos entre elas. O diagnóstico é feito por meio do exame físico da cavidade oral, sendo o tratamento baseado em técnicas cirúrgicas. Relata-se um caso bem-sucedido de oclusão de fístula oronasal utilizando somente resina acrílica autopolimerizável em um felino com histórico de espirros frequentes, secreção nasal purulenta crônica, halitose severa, emagrecimento e trauma sofrido há dois anos, que culminara em fratura da sínfise mandibular corrigida no mesmo período por cerclagem com fios de aço. No exame clínico verificou-se secreção nasal muco-purulenta fétida e a presença de uma grande fístula palatina na extensão do palato duro. Encaminhou-se o paciente para realização dos exames pré-cirúrgicos para posterior correção da fistula oronasal com o uso de resina acrílica autopolimerizavel. O procedimento foi bem sucedido visto que o animal deixou de apresentar os sinais clínicos e voltou a alimentar-se normalmente. A técnica mostrou-se eficaz e de fácil execução para correção de fenda palatina traumática de grande extensão em gato, na qual não se utilizou suturas ou flaps, pois os mesmos não eram praticáveis, podendo ser utilizada em substituição a outros métodos convencionais.

Cleft palate is a congenital or acquired communication between the oral and nasal cavities which can often contaminate the nasal cavity with saliva or food. The diagnosis is made by physical examination of the oral cavity and it is usually treated with surgery. We report a successful case of oronasal fistula occlusion using only acrylic resin in a feline. The patient presented with a history of frequent sneezing, chronic purulent nasal discharge, severe halitosis, weight loss and facial trauma suffered two years ago. The animal had mandibular symphysis fracture that was corrected by cerclage with steel wires. On clinical examinationit was observedthe presence of smelling nasal mucus, purulent secretions and the presence of a large cleft fistula in the extension of the hard palate. The patient was submitted to surgery in order to repair the oronasal fistula using acrylic resin. The surgery was curative eliminating clinical signs. The technique was effective and easy to be performed in this case of a traumatic cleft palate with large deffect in a cat. This technique can be used to replace other conventional methods, mainly in cases that the use of sutures or flaps are not feasible.

El paladar hendido es una comunicación congénita o adquirida entre las cavidades oral y nasal, lo que permite el paso de alimentos y líquidos entre ellos. El diagnóstico se realiza mediante un examen físico de la cavidad oral, siendo el tratamiento basado en técnicas quirúrgicas. Presentamos un caso de éxito de oclusión de la fístula oronasal usando sólo la resina acrílica autopolimerizável en un felino con histórico de frecuentes estornudos, secreción nasal purulenta crónica, halitosis severa, pérdida de peso y trauma sufrido hace dos años, culminando en fractura de la sínfisis mandibular, corregida en el mismo período por cerclaje con hilos de acero. En el examen clínico se verificó moco nasal maloliente, secreciones purulentas y la presencia de una gran fístula palatina en la extensión del paladar duro. Se hicieron exámenes pre-quirúrgicos para la posterior corrección de la fístula oronasal, mediante resina acrílica autopolimerizavel. El procedimiento fue exitoso porque el animal dejó de presentar signos clínicos y volvió a alimentarse normalmente. La técnica fue eficaz y de fácil ejecución para corrección de paladar hendido traumático de gran longitud en gato, en la cual no se utilizó suturas o aletas, ya que no eran viables y puede ser utilizado para sustituir a otros métodos convencionales.

Primary Aortoenteric Fistula to the Sigmoid Colon in Association with Intra-abdominal Abscess / 대한소화기학회지

Primary aortoenteric fistula (PAEF) is a rare but catastrophic cause of massive gastrointestinal bleeding. Diagnosis of PAEF is difficult to make and is frequently delayed without strong clinical suspicion. Timely surgical intervention is essential for patient's survival. We report on a case of an 86-year-old woman with no history of abdominal surgery, who presented with abdominal pain. Initially, computed tomography scan showed an intra-abdominal abscess, located anterior to the aortic bifurcation. However, she was discharged without treatment because of spontaneous improvement on a follow-up computed tomography scan, which showed a newly developed right common iliac artery aneurysm. One week later, she was readmitted due to recurrent abdominal pain. On the second day of admission, sudden onset of gastrointestinal bleeding occurred for the first time. After several endoscopic examinations, an aortoenteric fistula bleeding site was found in the sigmoid colon, and aortography showed progression of a right common iliac artery aneurysm. We finally concluded that intra-abdominal abscess induced an infected aortic aneurysm and enteric fistula to the sigmoid colon. This case demonstrated an extremely rare type of PAEF to the sigmoid colon caused by an infected abdominal aortic aneurysm, which has rarely been reported.

Magnetic resonance imaging to detect vesico-symphyseal fistula following robotic prostatectomy

Pubic complications following radical prostatectomy are rare. Osteitis pubis typically presents with symptoms related to irritation of the pubic rami including pain with ambulation and adduction of the leg. A 60-year-old male with prostatic adenocarcinoma underwent uneventful robotic assisted laparoscopic prostatectomy. The patient noted the onset of severe pubic pain exacerbated by ambulation approximately one month post-surgery. An abdominal/pelvic CT scan was negative for acute pathology. Due to continued discomfort, a multiplanar MRI of the pelvis was performed with and without intravenous contrast material (20 ml Omniscan). The MRI demonstrated irregularity of the bladder base and proximal urethra with a fistulous tract extending anteriorly in direct communication with the pubic symphysis joint space. Vague periarticular marrow edema-like signal and enhancement at the pubic symphysis was thought to represent osteitis pubis. The patient's symptoms resolved after one month of urethral catheter drainage, intravenous antibiotics, and anti-inflammatory therapy.

A Case of Primary Aortoenteric Fistula Mimicking Ulcer Bleeding / 대한소화기학회지

Primary aortoenteric fistula (PAEF) is a rare disease with a high mortality rate due to massive hemorrhaging and diagnostic difficulties. Although hemorrhagic regions can be identified by endoscopy, it is difficult to diagnose PAEF by this method. If PAEF is suspected, endoscopic procedure should be terminated and abdominal CT should be performed. Overlooking the herald bleeding of PAEF can lead to massive bleeding and death. An 85-year-old previously healthy male presented with a complaint of melena. Gastrointestinal endoscopy identified a hemorrhagic site in the third portion of the duodenum and endoscopic hemostasis was performed. However, during the procedure, it became apparent that the hemorrhage was probably not the result of a simple duodenal ulceration and abdominal CT was performed immediately. An aortic aneurysm connected to the duodenum was identified, confirming the diagnosis of PAEF. However, the patient died of massive hemorrhaging before an operation could be performed.

A Case of Intestinal Tuberculosis with Perianal Fistula Diagnosed after 30 Years / 대한소화기학회지

Tuberculosis can occur anywhere in the gastrointestinal tract. However, anorectal tuberculosis has rarely been reported. A 46-years-old male presented with abdominal pain and perianal discharge of 30 years' duration. The patient had received operations for anal fistula and inflammation three times. Although he had been taking mesalazine for the past three years after being diagnosed with Crohn's disease, his symptoms persisted. Colonoscopy performed at our hospital revealed cicatricial change of ileocecal valve and diffuse ulcer scar with mild luminal narrowing of the ascending, transverse, and descending colon without active lesions. Multiple large irregular active ulcers were observed in the distal sigmoid and proximal rectum. An anal fistula opening with much yellowish discharge and background ulcer scar was observed in the anal canal. However, cobble-stone appearance and pseudopolyposis were not present. Therefore, we clinically diagnosed him as having intestinal tuberculosis with anal fistula and prescribed antituberculosis medications. Follow-up colonoscopy performed 3 months later showed much improved multiple large irregular ulcers in the distal sigmoid colon and proximal rectum along with completely resolved anal fistula without evidence of pus discharge.

Absceso tiroideo con fístula del seno piriforme: tres casos clínicos / Thyroid abscess with pyriform sinus fistulae: 3 clinical cases

Thyroid abscess is an infrequent, potentially life-threatening condition. It accounts for 0,1 to 0,7 percent of thyroid pathology, usually occurring in patients with preexisting disease of the gland or more commonly, associated to local anatomical defects, such pyriform sinus fistulae. Three cases of thyroid abscess in children are presented, in which no bacterial etiology was confirmed. Intravenous antibiotics were used, cefotaxime, cloxacillin or clindamicin. Recurrence was confirmed in 2 of them, and a pyriform sinus fistulae was demostrated by esophagogram.

El absceso tiroideo es un cuadro infrecuente y una emergencia endocrina potencialmente fatal. Representa el 0,1 a 0,7 por ciento de las patologías tiroideas. Habitualmente se produce en pacientes con patología preexistente de la glándula o más frecuentemente, asociado a defectos anatómicos locales, como una fístula del seno piriforme. Presentamos 3 casos de abscesos tiroideos en escolares. Recibieron tratamiento antibiótico endovenoso de amplio espectro, a pesar de lo cual dos de ellos recidivaron precozmente. En dos de ellos se demostró una fístula del seno piriforme con esofagograma que se manejó quirúrgicamente.

Spontaneous fecal fistula in a neonate.

A 19-day-old male neonate was brought to us with a left upper quadrant abdominal wall defect through which bowel was prolapsing, with a double intussusception appearance typical of a patent omphalomesenteric duct. However, the history showed that the defect was not congenital, the child had a normal umbilicus, and at surgery the lesion was shown to be a mid jejunal perforation with prolapse of bowel along both the ascending and descending limbs. Histology revealed presence of inflammation and no heterotopic tissue. We believe this is the first ever report of such a fecal fistula and we speculate on the cause of this entity.

Gastropleural fistula: an unusual sequel of blunt chest trauma

In the October 2005 Earthquake in mountainous Azad Kashmir and adjacent areas in Pakistan, a young female sustained crush injury chest and upper abdomen. She remained hospitalized with lower chest pain. All initial investigations were normal and she was discharged symptom-free on conservative management. Six months later, she developed acute left sided chest pain and dyspnoea. Provisional diagnosis of empyema was made on X-ray, and tube thoracostomy was done. Diagnostic VATS revealed gastropleural fistula secondary to necrosis of herniated stomach. Resection of necrosed stomach, repair of diaphragm and decortication and transthoracic repair with lower thoracoplasty two months later was performed but both were unsuccessful. After another 02 months, a Roux-en-Y gastrojejunostomy at fistula site was fashioned which proved curative

[Tracheo-innominate artery fistula as a late onset tracheotomy complication: a case report]

Tracheo-innominate artery fistula [TIF] is a rare, life threatening and catastrophic complication, which may occur 7 to 14 days after surgery. The Incidence Rate of TIF is 0.1-1% and survival rate of patient is 14.3%. Herein, we describe TIF in a patient 50 days post tracheotomy, based on our research, it appears that our case is the first finding with the latest onset of TIF after tracheotomy, which now has been improved by early diagnosis and surgical treatment

Fístula perilinfática traumática: entidad otorrinolaringológica poco frecuente / Traumatic perilymphatic fistula: a rare otorhinolaryngological entity

La fístula perilinfática corresponde a una patología infrecuente en la práctica otorrinolaringológica diaria. Esta puede tener un origen congénito, de aparición espontánea o más frecuentemente postraumática, presentando habitualmente la triada clínica de hipoacusia, tinnitus y vértigo. A continuación se presenta el caso clínico de una paciente de 50 años atendida en el Servicio de Otorrinolaringología del Hospital Clínico de la Universidad de Chile, ingresada por un cuadro con clínica compatible, de inicio súbito luego de una perforación timpánica traumática autoinferida.

Perilymphatic fistula is an infrequent pathology in standard otorhinolaryngological practice. Fistulas of this sort may be of congenital, spontaneous or, more frequently post traumatic origin, normally presenting with the clinical triad of hearing loss, tinnitus and vertigo. The case of a 50 year old patient presenting with clinically compatible symptoms of sudden appearance after a self-infringed traumatic tympanic perforation is discussed.
