Hiperenrollamiento con torsión del cordón umbilical como causa de muerte fetal: reporte de caso / Hypercoiled umbilical cord torsion as a cause of fetal death: case report

Resumen La torsión del cordón umbilical como causa de muerte fetal es rara, con pocos casos reportados. No se conoce con claridad la causa y se presenta principalmente en el segundo trimestre de embarazo. Los factores de riesgo descritos son la longitud del cordón umbilical y el aumento del número de giros. Se reporta el caso de una paciente de 37 años, grávida 2, para 1 con embarazo de 23 semanas, con hallazgo ecográfico de muerte fetal. En el estudio de histopatología se evidenció el cordón umbilical con hiperenrollamiento y torsión a nivel de la unión feto-umbilical con oclusión de la luz de los vasos umbilicales como causa de muerte fetal. Se requiere la investigación de esta patología para determinar los factores de riesgo y el riesgo de recurrencia en futuros embarazos con el fin de establecer métodos de vigilancia fetal antenatal.

Abstract Torsion of the umbilical cord as a cause of fetal death is a rare occurrence, with few reported cases. The cause is not clearly known, and it transpires mainly in the second trimester of pregnancy; the risk factors described are the length of the umbilical cord with increased number of twists. The case of a 37-year-old woman is reported, gravida 2 para 1, 23 weeks pregnant with ultrasound diagnosis of fetal death. Histopathology revealed hypercoiled umbilical cord torsion at the point where the umbilical cord attaches to the fetus, with occlusion of the lumen of the umbilical vein, as a cause of fetal death. Further research of this pathology is required to determine the risk factors and risk of recurrence in future pregnancies that will allow the preparation of antenatal fetal surveillance methods.

Intestinal malrotation, mesocolic hernia, and Meckel diverticulum - differential diagnosis of abdominal pain in adults: case report and literature review

Intestinal malrotation is a congenital anomaly caused by incomplete rotation or absence of rotation of the primitive intestine along the axis of the upper mesenteric artery during embryonic development. Embryonic development and its anatomical variations were described by Dott in 1923. Intestinal malrotation is a rare condition among adults - prevalent in a mere 0.0001% to 0.19% of the population -, and it may be associated with other anatomical deformities. It can be asymptomatic or manifest with varying intensity, from obstruction to necrosis of intestinal segments. In general, this abnormality is diagnosed in the first year of life; however, symptomsmay appear later in life,making diagnosis in adults difficult on account of non-specific symptoms. In the present study, we report a case of intestinal malrotation associated with chronic non-specific symptoms progressing to mesenteric angina. (AU)

Bazo errante gigante con torsión del pedículo e infarto esplénico: reporte de un caso / Giant Wandering Spleen with torsion of the pedicle and splenic infarction: a case report

INTRODUCCIÓN: El bazo errante, es una entidad clínica poco común. Su espectro clínico varía desde enfermedad asintomática hasta complicaciones asociadas y su manejo es predominantemente quirúrgico. CASO CLÍNICO: Hombre, con cuadro clínico de dolor y masa abdominal palpable, con hallazgos tomográficos sugestivos de patología con asiento en retroperitoneo, con obstrucción intestinal secundaria; por laparotomía se identifica de forma incidental bazo ectópico solo fijado a través de pedículo vascular torsionado y signos de hipertensión portal, realizándose esplenectomía. CONCLUSIONES: La torsión esplénica es la complicación más frecuente del bazo errante, una entidad bastante rara con muy pocos casos publicados en Colombia.

BACKGROUND: The wandering spleen is an uncommon clinical entity. Its clinical spectrum varies from asymptomatic disease to associated complications and its management is predominantly by surgery. CLINICAL CASE: Man with clinical picture of pain and palpable abdominal mass, with tomographic findings suggestive of pathology with retroperitoneal seating, with secondary intestinal obstruction; by laparotomy incidentally, an ectopic spleen is identified, only fixed through a torsioned vascular pedicle and signs of portal hypertension, performing splenectomy. CONCLUSIONS: Splenic torsion is the most frequent complication of the errant spleen, a very rare entity with very few cases published in Colombia.

Vólvulo de la vesícula biliar como causa de abdomen agudo: reporte de caso y revisión de la literatura / Gallbladder volvulus as a cause of acute abdomen: case report and literature review

Resumen Antecedentes: El vólvulo de la vesícula biliar se produce por el giro de la vesícula sobre su mesenterio a lo largo del eje del conducto y arteria císticos, con afectación de la irrigación vascular de forma completa o incompleta, pudiendo existir ciertas características anatómicas predisponentes. Caso clínico: Masculino de 87 años quien cursó con abdomen agudo; sospechando cuadro de piocolecisto, se realizó exploración quirúrgica encontrando como hallazgos triple torsión vesicular y múltiples litos color oscuro; se realizó colecistectomia abierta, cursando con una evolución satisfactoria. Discusión: Se trata de una entidad infrecuente que puede simular una colecistitis aguda; generalmente tiene buen pronóstico cuando el diagnóstico se realiza a tiempo. El tratamiento de elección es la colecistectomía laparoscópica.

Flexible ureterorenoscopy in position or fusion anomaly: Is it feasible? / Ureterorrenolitotripsia flexível no tratamento de cálculos em rins anômalos: Qual a viabilidade?

Summary Objective: To analyze the results of flexible ureterorenoscopy (F-URS) with holmium laser in the treatment of kidney stones with ectopic and fusion anomalies (horseshoe kidney and rotation anomalies). Method: We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, anatomical abnormality, location and dimension of the renal calculi) and perioperative data (method of treatment, stone-free rate, number of days with DJ catheter and perioperative complications). Results: The mean stone size was 12.23 +/- 5.43 mm (range 6-22mm), located in the inferior (58.33%) and middle (16.76%) calyceal units, renal pelvis (16.67%) and multiple locations (8.33%). All 13 patients were treated with Ho-Yag laser, using dusting technique (25%), fragmentation and extraction of the calculi (58.33%) and mixed technique (16.67%). We did not have any severe perioperative complication. After 90 days, nine patients (75%) were considered stone free. Conclusion: Our data suggest that F-URS is a safe and feasible choice for the treatment of kidney stones in patients with renal ectopic and fusion anomalies.

Resumo Objetivo: Analisar os resultados da ureterorrenolitotripsia flexível (ULT-F) no tratamento de cálculos em rins com anomalia de posição e de fusão (rins em ferradura e rins com vício de rotação). Método: Realizamos a coleta prospectiva dos dados de 13 pacientes com anomalias de fusão e de posição submetidos a ULT-F entre abril de 2011 e abril de 2017. Analisaram-se dados clínicos (idade, gênero, IMC, anormalidades anatômicas, dimensão e localização dos cálculos) e perioperatórios (método de tratamento do cálculo, índice de stone free, tempo de cateter DJ e complicações perioperatórias). Resultados: Nos 13 pacientes, os cálculos mediam em média 12,23 mm +/- 5,43 mm (variando de 6 a 22 mm), em sua maioria distribuídos em apenas um grupo calicinal (58.33% em grupo calicial inferior, 16.67% em grupo calicial médio, 16,67% em pelve e 8,33% em múltiplos cálices). Todos os pacientes foram tratados com utilização de laser Ho-Yag, com fragmentação e retirada de cálculos em sete casos (58,33%), pulverização em três casos (25%) e técnica mista em dois casos (16,67%). Não houve complicações intraoperatórias ou pós-operatórias graves. Após 90 dias, nove pacientes tornaram-se stone free (75%). Conclusão: A ULT-F apresenta-se como método seguro e eficaz no tratamento de litíase em rins com anomalia de posição e de fusão.

Extralobar Pulmonary Sequestration with Hemorrhagic Infarction in a Child: Preoperative Imaging Diagnosis and Pathological Correlation

We describe a rare case of extralobar pulmonary sequestration with hemorrhagic infarction in a 10-year-old boy who presented with acute abdominal pain and fever. In our case, internal branching linear architecture, lack of enhancement in the peripheral portion of the lesion with internal hemorrhage, and vascular pedicle were well visualized on preoperative magnetic resonance imaging that led to successful preoperative diagnosis of extralobar pulmonary sequestration with hemorrhagic infarction probably due to torsion.

Rotação, twisting e torção miocárdicas avaliados pela ecocardiografia bidimensional (speckle tracking) / Myocardial rotation, twisting and torsion assessed by two-dimensional echocardiography (speckle tracking)

A disposição helicoidal das fibras miocárdicas confere ao coração movimento de rotação. O strain bidimensional permite analisar esses deslocamentos e calcular o twisting (diferença angular entre as rotações basal e apical) e a torção (twisting dividido pelo eixo maior da cavidade). Objetivo: Avaliar, pelo strain bidimensional, utilizando a técnica do speckle tracking, a rotação basal e apical, do VE, em indivíduos normais, em pacientes portadores de miocardiopatia chagásica e em pacientes com hipertrofia do VE. Material: Para analisar a rotação miocárdica, twisting e torção do VE, foram estudados 20 indivíduos sadios (média etária 52+-14 anos), 18 pacientes com miocardiopatia chagásica (média etária 55+-13 anos) e 12 pacientes com hipertrofia do VE (média etária 51+-8 anos). Métodos: Com ecocardiografia convencional, foram aferidas as dimensões e função do VE e, com strain bidimensional, estudado o strain longitudinal global, o strain, a rotação endocárdica e epicárdica basal e apical e calculados o twisting e a torção. Resultados: O diâmetro do VE foi, significativamente, maior nos pacientes com miocardiopatia chagásica. O índice de massa foi, significativamente, maior nos pacientes com hipertrofia do VE. A função do VE estava, significativamente, diminuída nos pacientes com miocardiopatia chagásica. A rotação, twisting e torção foram maiores na região endocárdica em todos os grupos. Rotação, twisting e torção estavam, significativamente, diminuídos nos pacientes com miocardiopatia chagásica e, significativamente, aumentados nos pacientes hipertróficos. Conclusão: A ecocardiografia bidimensional permite avaliar as rotações basal e apical do ventrículo esquerdo e calcular o twisting e a torção com boa acurácia e reprodutibilidade. A rotação endocárdica é maior em todos os grupos. O twisting e a torção estão diminuídos na miocardiopatia chagásica e aumentados na hipertrofia ventricular, permitindo separar os grupos de pacientes dos indivíduos normais...

Torsión omental como causa de abdomen agudo pediátrico / Omental torsion a rare cause of acute abdomen in children

INTRODUCCIÓN: La torsión omental constituye una causa infrecuente de dolor abdominal del niño, con una frecuencia relativa estimada de un caso por cada 200 cirugías realizadas por sospecha de apendicitis. Se sugiere que la incidencia de esta patología estaría en aumento paralelo a la obesidad infantil, y al mayor conocimiento diagnóstico con imagenología. PRESENTACIÓN DE CASOS: Cinco pacientes fueron tratados en el Hospital Luis Calvo Mackenna con diagnóstico postoperatorio de torsión o infarto omental entre enero de 2006 y enero de 2011.Todos se presentaron con dolor abdominal agudo en el cuadrante inferior derecho acompañado de otros síntomas fuertemente sugerentes de una apendicitis aguda. En ninguno de los 5 casos se obtuvo diagnóstico imagenológico de urgencias, por lo que recibieron manejo exclusivamente quirúrgico (omentectomía con o sin apendicectomía, vía minilaparotomía o laparoscopía), con resultados satisfactorios. El estudio histopatológico demostró congestión, hemorragia y/o necrosis omental, e inflamación periférica apendicular. DISCUSIÓN: Con un mayor acceso a imágenes y conocimiento de esta patología por el equipo médico, se hace posible realizar el diagnóstico de forma preoperatoria, lo que es decisivo para posibilitar diferentes alternativas terapéuticas y puede evitar la cirugía restringiéndola a casos seleccionados.

INTRODUCTION: Omental torsion is a rare cause of abdominal pain in children, with an estimated incidence of one for every 200 appendectomies performed. A rise in that number has been projected, parallel to a higher prevalence of childhood obesity and a higher accuracy in diagnostic imaging. CASE REPORT: Five patients had a postoperative diagnosis of omental torsion in Hospital Luis Calvo Mackenna between January of 2006 and January 2011. All of them started an acute abdominal pain in right iliac fossa and general symptoms that resembled acute appendicitis. None of them had a correct diagnosis by emergency imaging; thereby a surgical resolution – open or laparoscopic omentectomy with or without appendectomy - was indicated with good outcomes. Histopathological study showed congestion, hemorrhage and/or omental necrosis, and periappendicular inflammation. DISCUSSION: With more readily available imaging studies and a higher index of suspicion, a preoperative diagnosis of omental torsion could be achieved, potentially avoiding unnecessary surgery.

Torsión primaria de epiplón: caso clínico / Primary omental torsion: report of one case

We report a 40 years old female consulting in the emergency room for abdominal pain and a mass in the left lower quadrant. An abdominal CAT sean showed an omental torsion. The patient was operated, excising the involved omentum. The postoperative period was uneventful and the patient was discharged three days after admission.

El objetivo de este trabajo es presentar el caso clínico de una paciente con torsión de epiplón manejado en nuestra institución. Se trata de una paciente de sexo femenino de 40 años de edad, que se presenta al servicio de urgencias por clínica de dolor abdominal de una semana de evolución asociado a masa abdominal en flanco izquierdo, en quien se realiza tomografía que revela cambios compatibles con torsión de epiplón por lo cual es llevada a cirugía realizándose resección de todo el omento.

Pinzamiento femoroacetabular: Conceptos básicos en una nueva causa de dolor inguinal: [revisión] / Femoroacetabular impingement as a cause of inguinal pain: [review]

Femoro-acetabular impingement is an anatomical disturbance of the hip, caused by a deformity of the acetabulum, femur or both that causes an abnormal contact between both structures during certain movements. Its prevalence is 10 to 15 percent and causes chronic inguinal pain. It can be confused with several other causes of inguinal pain such as hernias, facet syndromes, a renal colic, etc. Patients with this condition are usually young individuals with inguinal pain that may appear after a minor trauma. During examination, pain may be elicited by infernal rotation and abduction movements of hip, flexed in 90°. Plain hip X ray is the most commonly used diagnostic method. Non-steroidal anti-inflammatory drugs and physical therapy can be used to alleviate pain, but the definitive treatment is surgical.

A Case of Carotid Aneurysm in Familial Retinal Arterial Tortuosity

A 44-year-old woman who showed recurrent vitreous hemorrhages with vascular tortuosity received CT angiography which revealed an internal carotid artery aneurysm. A case of internal carotid aneurysm was associated with a pattern of retinal arteriolar tortuosity pathognomic for familial retinal arterial tortuosity (fRAT), suggesting possible involvement of the cerebral circulation. We present a case of internal carotid aneurysm associated with a pattern of retinal arteriolar tortuosity pathognomic for fRAT.

Apendagite epiplóica: aspectos clínicos e radiológicos / Epiploic appendagitis: clinical and radiological aspects

Apendagite epiplóica é uma doença inflamatória abdominal incomum. Foram avaliados, retrospectivamente, os prontuários de 44 pacientes com diagnóstico de apendagite epiplóica atendidos no Hospital Barra D’Or, Rio de Janeiro, RJ, no período entre fevereiro de 2005 e setembro de 2006, sendo 82 por cento homens e 18 por cento mulheres, com média de idade de 44,7 anos. Buscou-se caracterizar o quadro clínico-laboratorial e radiológico desses pacientes. As alterações laboratoriais mais freqüentes foram piúria e leucocitose, cada uma presente em 5 por cento dos casos. O diagnóstico foi feito por tomografia computadorizada de abdome com achado de lesão ovóide em cólon descendente em 52 por cento dos pacientes. A resolução do quadro clínico foi obtida com tratamento conservador.

Epiploic appendagitis is an uncommon inflammatory abdominal disease. Data of 44 patients with a clinical diagnosis of appendagitis were retrospectively evaluated regarding laboratory and imaging findings. They were admitted to Barra D’Or Hospital, Rio de Janeiro, RJ, from February 2005 to September 2006. Eighty-two percent were male and 18 were female, with median age of 44.7 years. The most frequent laboratory findings were hematuria in urinalysis and leucocitosis, presenting in 5 percent of cases each. Diagnosis was obtained through computed tomography showing paracolic oval lesions, mainly over the descending colon in 52 percent of patients. Patients were treated with analgesics and anti-inflammatory in an outpatient basis. Recovery was uneventful under conservative treatment.

Untwisting and fixation of ovarian torsion in early pregnancy

Adnexal torsion is a common gynecological emergency with an incidence of around 2-3%. Torsion may present as acute or chronic lower abdominal pain, which can be intermittent or constant. Risks of prolonged torsion include atrophy, necrosis, loss of ovarian functions and even premature menopause. [2] Traditionally, adnexal torsion has been treated in a radical manner without prior detorsion, due to fear of embolus migration from the twisted pedicle[3]. As there 1909, ovrian conservation was proposed to avoid castration in young women[4]. The concern of miscarriage due to removal of corpus luteum in early pregnancy encourages conservative surgery for ovarian torsion during pregnancy. We report two cases of ovarian torsion happened in the first trimester of pregnancy which successfully treated by untwisting and fixation of the affected adnexa

Torsión omental: una causa de abdomen agudo / Omental torsion: an acute abdomen etiology

Introducción. La torsión omental es una causa poco común de abdomen agudo que usualmente semeja apendicitis aguda. La mayoría de los casos son diagnosticados durante laparotomía. Puede ser primaria o bien secundaria; la primera se presenta sin evidencia de patología intraabdominal preexistente. Material y métodos. Del primero de enero del 2001 al 31 de diciembre del 2005, se llevó a cabo un estudio descriptivo, observacional, longitudinal y retrospectivo en pacientes con diagnóstico preoperatorio de apendicitis aguda con el objetivo de conocer la incidencia de apendicitis aguda confirmada por anatomopatología y la incidencia de torsión omental. Resultados. Se incluyeron 2,135 pacientes sometidos a cirugía con el diagnóstico preoperatorio de apendicitis aguda de los cuales hubo confirmación histológica posoperatoria en el 91.71% de los casos. Se encontraron 8 casos de torsión omental, para una incidencia del 0.37%, que se diagnosticaron todos transoperatoriamente. Se detectó mayor frecuencia en las primera y cuarta décadas de la vida; el 75% se observó en adultos. El 62.5% de los casos presentó torsión secundaria. Discusión. La torsión omental es una causa poco frecuente de abdomen agudo cuyo principal diagnóstico diferencial es apendicitis aguda. En nuestra serie, encontramos una incidencia de torsión omental dos veces superior a la reportada en la literatura (0.16 contra 0.37), así como una diferencia en cuanto a su distribución por grupos de edad y por sexo.

INTRODUCTION: Omental torsion is an uncommon cause of acute abdomen, usually mimicking acute appendicitis; almost all described cases are diagnosed with laparotomy. It can be a primary or secondary condition. Primary torsion occurs without evidence of intrabdominal abnormalities. MATERIAL AND METHODS: Retrospective, observational, longitudinal, descriptive study carried out between January 2001 and December 2005. Patients diagnosed as acute appendicitis were included and we assessed diagnostic accuracy by means of anatomopathology and omental torsion incidence. RESULTS: 2135 patients were included; diagnostic accuracy was 91.71%. Eight omental torsion cases were identified, with an incidence of 0.37% and all diagnosed with laparotomy. Patients in the first and fourth decades of life were mostly affected; 75% of the cases were observed in adults, and 62.5% displayed secondary torsion. DISCUSION: Omental torsion is a rare cause of acute abdomen. Acute appendicitis is a frequent differential diagnosis that should be taken into account. In our series, we found a two-fold higher incidence of omental torsion, compared with previously reported incidence data. We also found a difference in age and sex distribution among patients with this diagnosis.

Acute scrotum -- etiology and management.

OBJECTIVE: Acute scrotal pain is a common urological emergency. Urgent exploration is the standard means of management, since no investigation can confidently exclude torsion of testis from the differential diagnosis. METHODS: A review of all boys presenting with acute scrotal pain who underwent emergency scrotal exploration between January 1983 and March 2003 was performed. RESULTS : 195 boys were included in this study. They were divided into 3 groups: group 1-73 with epididymo-orchitis, group 2-63 with torsion of testicular appendages and group 3- 57 with spermatic cord torsion. The patients in group 2 were older than group 1, also patients in group 1 were older than group 3. During neonatal period the most common pathology was spermatic cord torsion, whereas in prepubertal period torsion of appendages was more common. In all boys, mean duration of pain at presentation was 2.11 days. Epididymo-orchitis was diagnosed in 37% of patients, with torsion of the appendages being the next most common entity. Testicular torsion was diagnosed in 29% of patients. In the group with testicular torsion salvage rate of testis was 37% because of late admission. The perioperative morbidity and mortality was not seen in any of the groups. CONCLUSION: We believe that any boy with acute scrotal pain and any suspicion of testicular torsion in physical examination must be applied routine surgical exploration.

Torsion of the greater omentum with inguinal hernia.

Torsion of the greater omentum is an uncommon cause of acute abdomen, often diagnosed only intraoperatively. We report a 30-year-old man with torsion of the greater omentum in association with inguinal hernia, diagnosed on CT scan and managed conservatively.
