ABSTRACT

The aim of this study was to evaluate the effects of Psyllium (PSY) and Carboxymethylcellulose (CMC) administration on fecal elimination of sand in horses with asymptomatic sand accumulations. Eight horses were selected from sandy areas and randomly divided into 2 groups of four animals. The subjects were treated either with CMC or PSY. The presence of intestinal sand was confirmed through radiography and glove sedimentation test. The study was performed in two phases, with a 7-day interval. In phase I, all the animals received 8 liters of warm water; in phase II, the CMC group received 8 liters of water + 1g/kg of CMC, whereas the PSY group received 8 liters of water + 1g/kg of PSY. All administrations were performed through nasogastric intubation and fractionated in 2 equal volume administrations with an interval of two hours. General and specific physical examination of the digestive system were performed in conjunction with abdominal ultrasonography before the administrations and after 6, 12, 24, 36 and 48 hours, aiming to evaluate intestinal motility and presence of sand. All the feces eliminated by the animals within the 72 hours following the administrations were quantified, diluted and sedimented in order to calculate the sand output (g/kg of feces). All the animals were also subjected to radiographic examination to quantify sand accumulation prior to phase I and after 72 hours of phases I and II. No adverse effects were observed after the treatments. It was possible to notice higher sand elimination in both groups during the phase I, whereas no difference was observed in sand elimination rates between the groups in phase II. The radiographic scores presented differences between the initial timepoint and 72h in phases I and II for both groups. Based on the sand elimination rates and radiographic score, this study demonstrated that sand output was greater after administration of water alone, compared to CMC and Psyllium, leading to the inference that removal of the sandy environment and prevention of sand re-ingestion are effective measures for the elimination of sand from the colon of horses with asymptomatic sand accumulations.(AU)


O objetivo deste estudo foi avaliar os efeitos da administração do psyllium (PSY) e da carboximetilcelulose (CMC) sobre a eliminação fecal de areia em equinos com sablose assintomática. Oito equinos com confirmação radiográfica de sablose assintomática foram divididos em dois grupos (grupo CMC e grupo PSY). O estudo foi realizado em duas fases, com intervalo de sete dias. Na fase 1, todos os animais receberam 8L de água; na fase 2, o grupo CMC recebeu 8L de água + 1g/kg de CMC e o grupo PSY recebeu 8L de água + 1g/kg de PSY. Antes da administração de cada solução e após seis, 12, 24, 36 e 48 horas, foram realizados exame físico e ultrassonografia abdominal. Todas as fezes eliminadas em 72 horas foram avaliadas para quantificar a eliminação de areia (g/kg de fezes). Antes da fase 1 e após 72 horas das fases 1 e 2, o exame radiográfico foi realizado para quantificar o escore de acúmulo de areia. Houve maior eliminação de areia após a administração de água em comparação com a administração de CMC, e não se observou diferença entre a CMC e o PSY. Uma redução significativa nos escores radiográficos de acúmulo de areia foi observada após a administração de água, bem como a manutenção dos escores após a administração da CMC e do PSY. Com base na produção de areia e no escore radiográfico, este estudo sugere que a remoção do ambiente arenoso, impedindo a reingestão de areia, é uma medida eficaz para a eliminação da areia do cólon de cavalos com acúmulos de areia assintomáticos.(AU)

ABSTRACT

ABSTRACT Objective: The objective of this study was to develop and validate a computational tool to assist radiological decisions on necrotizing enterocolitis. Methodology: Patients that exhibited clinical signs and radiographic evidence of Bell's stage 2 or higher were included in the study, resulting in 64 exams. The tool was used to classify localized bowel wall thickening and intestinal pneumatosis using full-width at half-maximum measurements and texture analyses based on wavelet energy decomposition. Radiological findings of suspicious bowel wall thickening and intestinal pneumatosis loops were confirmed by both patient surgery and histopathological analysis. Two experienced radiologists selected an involved bowel and a normal bowel in the same radiography. The full-width at half-maximum and wavelet-based texture feature were then calculated and compared using the Mann-Whitney U test. Specificity, sensibility, positive and negative predictive values were calculated. Results: The full-width at half-maximum results were significantly different between normal and distended loops (median of 10.30 and 15.13, respectively). Horizontal, vertical, and diagonal wavelet energy measurements were evaluated at eight levels of decomposition. Levels 7 and 8 in the horizontal direction presented significant differences. For level 7, median was 0.034 and 0.088 for normal and intestinal pneumatosis groups, respectively, and for level 8 median was 0.19 and 0.34, respectively. Conclusions: The developed tool could detect differences in radiographic findings of bowel wall thickening and IP that are difficult to diagnose, demonstrating the its potential in clinical routine. The tool that was developed in the present study may help physicians to investigate suspicious bowel loops, thereby considerably improving diagnosis and clinical decisions.


RESUMO Objetivo: O objetivo deste estudo foi desenvolver e validar uma ferramenta computacional para auxiliar as decisões radiológicas na enterocolite necrotizante. Metodologia: Pacientes que exibiam sinais clínicos e evidências radiográficas do estágio 2 ou superior de Bell foram incluídos no estudo, que resultou em 64 exames. A ferramenta foi usada para classificar o aumento localizado da espessura da parede intestinal e a pneumatose intestinal com medidas de largura total a meia altura e análises de textura baseadas na decomposição da energia wavelet. Os achados radiológicos de aumento suspeito da espessura da parede intestinal e das alças na pneumatose intestinal foram confirmados pela cirurgia e análise histopatológica do paciente. Dois radiologistas experientes selecionaram um intestino afetado e um intestino normal na mesma radiografia. A largura total a meia altura e a característica da textura baseada em wavelet foram então calculadas e comparadas com o uso do teste U de Mann-Whitney. Foram calculados a especificidade, sensibilidade, valores preditivos positivos e negativos. Resultados: Os resultados da largura total a meia altura foram significativamente diferentes entre a alça normal e a distendida (mediana de 10,30 e 15,13, respectivamente). Medidas de energia wavelet horizontal, vertical e diagonal foram avaliadas em oito níveis de decomposição. Os níveis 7 e 8 na direção horizontal apresentaram diferenças significativas. Para o nível 7, as medianas foram 0,034 e 0,088 para os grupos normal e com pneumatose intestinal, respectivamente, e para o nível 8, as medianas foram 0,19 e 0,34, respectivamente. Conclusões: A ferramenta desenvolvida pode detectar diferenças nos achados radiográficos do aumento da espessura da parede intestinal e PI de difícil diagnóstico, demonstra seu potencial na rotina clínica. A ferramenta desenvolvida no presente estudo pode ajudar os médicos a investigar alças intestinais suspeitas e melhorar consideravelmente o diagnóstico e as decisões clínicas.

ABSTRACT

Resumen: La obstrucción duodenal congénita agrupa un amplio espectro de anomalías en el desarrollo del intestino delgado; se clasifica según su etiología tanto en extrínseca como intrínseca. Su presentación es relativamente común, teniendo una incidencia de 1: 2.500-10.000 nacidos vivos y normalmente presenta asociación con aneuploidías (como la trisomía 21) y malformaciones cardíacas. Las imágenes tienen un papel importante en la aproximación diagnóstica y la radiografía de abdomen simple, es el primer escalón en la aproximación de la obstrucción intestinal. El tratamiento involucra una exploración quirúrgica del abdomen con corrección de los defectos encontrados. Este es un reporte de caso de un neonato que presentó obstrucción duodenal congénita de etiología tanto extrínseca (malrotacion intestinal y bandas de Ladd) como obstrucción intrínseca (membranas duodenales).


Abstract: Congenital duodenal obstruction groups together a broad spectrum of abnormalities in the development of the small intestine; it is classified according to its etiology as both extrinsic and intrinsic. Its presentation is relatively common, having an incidence of 1: 2.500-10.000 live births and it is normally associated with aneuploidy (such as trisomy 21) and cardiac malformations. Images play an important role in the diagnostic approach, with simple abdominal radiography being the first step in the approximation of intestinal obstruction. The treatment corresponds to a surgical exploration of the abdomen with resolution of the defects found. This is a case report of a newborn who presented congenital duodenal obstruction of both extrinsic etiology (intestinal malrotation and Ladd bands) and intrinsic obstruction (duodenal membranes).

ABSTRACT

PURPOSE: This study aimed to evaluate the clinical and radiologic findings suggestive of spontaneous intestinal perforation (SIP) in extremely-low-birth-weight infants (ELBWIs) with persistent gasless abdomen, and to investigate the usefulness of abdominal ultrasonography for the diagnosis of SIP. METHODS: In total, 22 infants with birth weights less than 1,000 g who showed persistent gasless abdomen on simple abdominal radiography were included. Perinatal, neonatal, and perioperative clinical findings were retrospectively reviewed, and the risk factors for intestinal perforation were evaluated. Abdominal sonographic findings suggestive of intestinal perforation were also identified, and postoperative short-term outcomes were evaluated. RESULTS: In total, eight of the 22 infants (36.4%) with gasless abdomen had SIP. The number of infants with patent ductus arteriosus who were treated with intravenous ibuprofen or indomethacin was significantly higher in the SIP group than in the non-SIP group (P<0.05). Greenish or red gastric residue, abdominal distension, or decreased bowel sound were more frequent in infants with SIP (P<0.05), in addition to gray or bluish discoloration of abdomen, suggestive of meconium peritonitis (P<0.05). Pneumoperitoneum on simple abdominal radiography was found in only one of the eight infants (12.5%) with SIP. Intramural echogenicity and echogenic extramural material on abdominal ultrasonography were exclusively observed in infants with SIP. Four infants (50%) with SIP died after surgical intervention. CONCLUSION: Intestinal perforation may occur in ELBWIs with gasless abdomen. As intramural echogenicity and extraluminal echogenic materials on abdominal ultrasonography are indicative of SIP, this technique could be useful for diagnosing SIP.

ABSTRACT

ABSTRACT Renal replacement lipomatosis is a condition characterized by varying degrees of renal parenchymal atrophy and perirenal fibrofatty proliferation secondary to chronic inflammation such as xanthogranulomatous pyelonephritis. In severe cases, imaging findings can be misdiagnosed as retroperitoneal liposarcoma.

ABSTRACT

PURPOSE: To characterize the course of treatment for nonmonosymptomatic enuresis with overactive bladder (OAB) in a real clinical setting. METHODS: Data from 111 OAB patients with moderate to severe enuresis were analyzed. The baseline analysis included a questionnaire, voiding diary, uroflowmetry with postvoid residual urine measurement, and plain abdominal radiography of the kidneys, ureters, and bladder (KUB). Following standard urotherapy for 1 month, anticholinergic medication was administered with or without laxatives. Desmopressin was added if there was a partial response to OAB. Patients were followed every 3 months to evaluate the status of OAB and enuresis. Multivariate analysis was performed to identify predictors associated with the lack of complete response (CR) in enuresis at 12 months. RESULTS: Following 12 months of treatment, 64% and 88% of patients experienced at least partial response in enuresis and OAB, respectively. Urgency improved more quickly than enuresis, supporting the need to address daytime symptoms before enuresis. Seventy-nine patients (71%) had fecal impaction on KUB and/or subjective constipation. The combination of anticholinergics with either laxatives or desmopressin fared better than anticholinergics alone. Daytime incontinence and anticholinergics-only treatment were associated with a lack of CR during 12 months of treatment. CONCLUSIONS: The data confirmed the validity of addressing OAB before treating enuresis. The results of this study also highlight the need to address fecal impaction. Patients should be counseled about the need for a prolonged course of treatment before starting treatment. Anticholinergics should be accompanied with either desmopressin or laxatives for better control of enuresis.

ABSTRACT

We report a case of a 61-year-old woman with a large atrial septal defect (ASD) that was detected incidentally on chest radiography and computed tomography when she presented with sepsis. Echocardiography confirmed a large secundum ASD with left-to-right shunt flow, right heart dilatation and severe pulmonary hypertension. The patient had a poor clinical outcome despite intensive care and eventually passed away. Haemodynamically significant ASDs have a known association with increased morbidity and mortality, and their early detection and closure cannot be understated. This article aimed to highlight the imaging features of ASD, with special emphasis on the routine chest radiograph. The pathophysiology and clinical manifestations of ASD are also briefly discussed.

ABSTRACT

Non-infectious complications of peritoneal dialysis (PD) are relatively less common than infectious complications but are a potentially serious problem in patients on chronic PD. Here, we present a case of a non-infectious complication of PD in a 13-year-old boy on chronic PD who presented with symptoms such as hypertension, edema, dyspnea, and decreased ultrafiltration. Chest and abdominal radiography showed pleural effusion and migration of the PD catheter tip. Laparoscopic PD catheter reposition was performed because PD catheter malfunction was suspected. However, pleural effusion relapsed whenever the dialysate volume increased. To identify peritoneal leakage, computed tomography (CT) peritoneography was performed, and a defect of the peritoneum in the left lower abdomen with contrast leakage to the left rectus and abdominis muscles was observed. He was treated conservatively by transiently decreasing the volume of night intermittent PD and gradually increasing the volume. At the 2-year follow-up visit, the patient had not experienced similar symptoms. Patients on PD who present with refractory or recurrent pleural effusion that does not respond to therapy should be assessed for the presence of infection, catheter malfunction, and pleuroperitoneal communication. Thoracentesis and CT peritoneography are useful for evaluating pleural effusion, and timely examination is important for identifying the defect or fistula.

ABSTRACT

Introducción. El término "body packer" hace referencia a sujetos portadores de objetos intraabdominales extraños, que contienen drogas ilícitas con fines de contrabando. La mayoría son pacientes asintomáticos, en quienes se instaura conducta expectante, observación clínica estrecha y administración de medicamentos para la evacuación de los paquetes, con miras a prevenir posibles complicaciones, como obstrucción intestinal o intoxicación, asociadas a su transporte intraabdominal. Materiales y método. Se llevó a cabo un estudio transversal de linealidad retrospectiva en pacientes admitidos en la E.S.E Hospital Universitario del Caribe entre los años 2014 y 2016,bajo la sospecha diagnóstica de "body packer". Luego de una revisión de las bases de datos institucionales se analizaron variables demográficas y clínicas de los sujetos incluidos en el estudio. Resultados. Se incluyeron 4 pacientes de género masculino, entre los 22 y 66 años de edad. La cantidad de cápsulas transportadas en promedio fue de 43, para una máxima de 74. La cocaína fue la sustancia que más se identificó. Para la evacuación de los paquetes se empleó irrigación intestinal con polietilenglicol. El tiempo de evacuación máximo fue de 48 horas y no hubo complicaciones asociadas al manejo proporcionado. Discusión. Estudios respecto al tema, como este, confirman la seguridad del manejo conservador del paciente asintomático y apoyan el uso de polietilenglicol dada su efectividad para lograruna limpieza intestinal completa y por su bajo riesgo de complicaciones asociado a su uso en comparación con otros métodos, así como la menor necesidad de intervenciones quirúrgicas. Se requieren estudios prospectivos aleatorizados controlados a partir de los cuales se determinen, con base en mayor evidencia, las mejores prácticas a seguir


Introduction. The term "body packer" refers to subjects carrying intraabdominal foreign objects that contain illicit drugs for contraband purposes. The majority of patients are asymptomatic, in whom expectant management is established, with close clinical observation and administration of medications for evacuation of the packages, with prevention of possible complications such as intestinal obstruction or intoxication associated with intraabdominal transport. Materials and method. A retrospective linearity cross sectional study was carried out in patients admitted to the Hospital Universitario del Caribe, Cartagena, Colombia, under the diagnostic suspicion of "body packer" in the period 2014 and 2016. After a review of the institutional databases, demographic and clinical variables of the study subjects were analyzed. Results. Four patients were included, male, ages 22 to 66 years. The average number of capsules transported was 43, with maximum of 74. Cocaine was the substance mainly identified. Intestinal irrigation with polyethylene glycol was used for intestinal evacuation. The maximum evacuation time was 48 hours and there were no complication associated with the given management. Discussion. The existing studies on the subject, as well as this one, confirm the safety of the conservative management in the asymptomatic patient and support the effectiveness of polyethyleneglycol in achieving complete intestinal cleansing and the low risk of complications associated with its use with respect to other methods, together with diminished need for surgical intervention. Controlled randomized prospective studies are required to provide greater evidence in order to determine the best practice to be followed

ABSTRACT

Capsule endoscopy is a technique that allows the study of the small intestine, through a device that is swallowed by the patient, capturing images as it travels through the digestive tract. Capsule retention is the most serious complication. We report the case of a 69 year-old male presenting with iron deficiency anemia, with normal upper endoscopy and colonoscopy; but obscure gastrointestinal bleeding was diagnosed and therefore a study with capsule endoscopy was requested. The patient evolves with retained capsule in the small intestine with ulcerated stenosis as shown by imaging. This finding was confirmed by enteroscopy with biopsy, without being able to extract the capsule. Medical management with corticosteroids was indicated for intestinal obstruction secondary to inflammatory stenosis in the context of Crohn's disease: The capsule was expelled after 21 days of ingestion, with a positive outcome


La cápsula endoscópica es una técnica que permite el estudio del intestino delgado, mediante un dispositivo que es deglutido por el paciente y captura imágenes en su recorrido por el tubo digestivo. La complicación más grave es la retención de la cápsula. Se reporta el caso de un paciente de sexo masculino, de 69 años con anemia ferropénica, con endoscopia alta y colonoscopia normal; planteándose sangrado gastrointestinal de origen oscuro por lo que se solicita estudio con cápsula endoscópica. El paciente evoluciona con retención de la cápsula en intestino delgado, visualizándose en las imágenes la presencia de estenosis ulcerada, hallazgo que se confirma mediante enteroscopia con toma de biopsias, sin lograr extraer la cápsula. Se indica manejo médico con corticoides por obstrucción intestinal secundario a estenosis inflamatoria en contexto de enfermedad de Crohn, expulsando espontáneamente la cápsula al día 21 de su ingestión, sin complicaciones.

ABSTRACT

Peritoneal dialysis (PD) is associated with the development of various complications, such as exit site infection or peritonitis, and rarely, intestinal obstruction in prolonged PD patients with recurrent peritonitis. However, post-colonoscopy acute intestinal obstruction has not been reported in PD patients to date. Herein, we report a case of severe ileus after a colonoscopy without previous episodes of peritonitis in a PD patient. A 51-year-old man undergoing PD for 7 years visited our emergency department due to severe abdominal pain and vomiting after colonoscopic polypectomy. A simple abdominal radiography and abdominal computed tomography showed ileus with collapsed distal ileal loop. A peritoneal dialysate study revealed no evidence of peritonitis. The patient was treated with decompression therapy, and ileus was successfully treated without complications. This case suggests that it is not only necessary to prevent peritonitis, but also important to monitor the development of ileus after colonoscopy in PD patients.

ABSTRACT

A 14-year-old Maltese dog presented with progressive exophthalmos and external deviation of the right eye. Ultrasonography revealed the presence of a retrobulbar mass and fine-needle aspiration cytology was performed, which detected a malignant mass. There was no evidence of metastasis on thoracic and abdominal radiography. Computed tomography showed no invasion into the bony orbit and no metastasis to the lung or lymph nodes. Exenteration was performed to remove the mass completely. Malignant peripheral nerve sheath tumor was confirmed by histopathological examination.
