Congenital diaphragmatic Bochdaleck hernia: Case report

Congenital diaphragmatic Bochdaleck hernia is an anatomical defect of the diaphragm, which allows protrusion of abdominal viscera into the chest, causing serious pulmonary and cardiac complications in the neonate. In this study we aimed to present a case of congenital Bochdaleck hernia. We investigated a 40 weeks old child, with a pregnancy carried out in a public hospital in Passo Fundo, Rio Grande do Sul, Brazil. We suggest that if diagnosis occurs in the prenatal period, the prognosis of this disease improves. As a consequence, it allows the parity of the fetus to occur in a higher complexity center, optimizing the chances of survival. © 2012 Lava et al.; licensee BioMed Central Ltd.

Doença do disco intervertebral Hansen tipo II em cães: fisiopatologia, abordagem clínico-cirúrgica e controvérsias

Protrusion of the intervertebral disc can cause chronic progressive compression of the spinal cord, and the neurological associated signs vary according to anatomical location, duration and dynamic force of compression. The type II disc disease is not fully understood, and there are many controversies about is clinical significance and best form of treatment. The most important aspect of conservative treatment is rest and physiotherapy associated with mild exercise, and use of corticosteroids to reduce vasogenic edema. The spinal decompression by surgery for removal of disc material from within the medullary canal is the surgical treatment of choice in type I disc disease, but has technical limitations in the type II disc disease. The purpose of this paper is to review the pathophysiology and treatment of chronic intervertebral disc disease and discuss the controversies in medical treatment and the use of some traditional and new surgical techniques.

Mielografia lombar no diagnóstico de extrusão do disco intervertebral toracolombar em cães: estudo prospectivo

Thoracolumbar disk extrusion is the most common cause of extradural compression of the spinal cord in dogs. Myelography is one of the most commonly performed techniques for the diagnosis of this affection. This study aimed to evaluate the applicability and effectiveness of lumbar myelography in the diagnosis of thoracolumbar intervertebral disk extrusion in dogs, as well as its major complications. Twenty dogs were used in this study. Animals were included when neurological examination suggested thoracolumbar spine lesion, myelography was used as a complementary diagnostic method, and diagnosis of disk extrusion was surgically confirmed. The accuracy of the exam to predict location and lateralization of extruded disk material were evaluated, as well as complications associated to the procedure. Lumbar myelography exhibited 95% and 60% accuracy for location and lateralization of the lesion, respectively, with minimal complications.

Uso de hialuronidato de sódio para tratamento de deslocamento anterior de disco articular com travamento bucal

Temporomandibular joint disorders causing limitation of mouth opening and pain may be related to the restriction of slipping or forward displacement of the mandibular condyle. Temporomandibluar arthrocentesis is the lavage of the joint and is regarded as a simple method that produces good results in patients with these symptoms. This article reports a case of disc displacement and closed lock in a patient who reported limited mouth opening and pain as the main symptoms. The treatment proposed was arthrocentesis and lavage, combining a corticosteroid with a sodium hyaluronate solution. It is concluded that arthrocentesis is a simple, efficient and barely invasive method for particular types of temporomandibular joint disorders and should be considered before opting for more invasive surgical procedures.

Early fetoscopic tracheal occlusion for extremely severe pulmonary hypoplasia in isolated congenital diaphragmatic hernia: Preliminary results

Objective: To evaluate the effect of early fetoscopictracheal occlusion (FETO) (22–24 weeks’ gestation) onpulmonary response and neonatal survival in cases ofextremely severe isolated congenital diaphragmatic hernia(CDH). Methods: This was a multicenter study involving fetuseswith extremely severe CDH (lung-to-head ratio < 0.70,liver herniation into the thoracic cavity and no otherdetectable anomalies). Between August 2010 and December 2011, eight fetuses underwent early FETO. Datawere compared with nine fetuses that underwent standard FETO and 10 without fetoscopic procedure fromJanuary 2006 to July 2010. FETO was performed undermaternal epidural anesthesia, supplemented with fetalintramuscular anesthesia. Fetal lung size and vascularitywere evaluated by ultrasound before and every 2 weeksafter FETO. Postnatal therapy was equivalent for bothtreated fetuses and controls. Primary outcome was infantsurvival to 180 days and secondary outcome was fetalpulmonary response. Results: Maternal and fetal demographic characteristicsand obstetric complications were similar in the threegroups (P > 0.05). Infant survival rate was significantlyhigher in the early FETO group (62.5%) comparedwith the standard group (11.1%) and with controls(0%) (P < 0.01). Early FETO resulted in a significantimprovement in fetal lung size and pulmonary vascularitywhen compared with standard FETO (P < 0.01). Conclusions: Early FETO may improve infant survival byfurther increases of lung size and pulmonary vascularityin cases with extremely severe pulmonary hypoplasia inisolated CDH. This study supports formal testing of thehypothesis with a randomized controlled trial.

Gastric Torsion from an Intestinal Hernia Through a Rent in the Gastrosplenic Ligament in a Horse

The present report describes an 8-year-old gelding presenting with signs of severe abdominal pain. After performing a thorough physical examination, including rectal palpation and additional diagnostic tests, an exploratory laparotomy was recommended. The jejunum was found herniated through the gastrosplenic ligament, and the stomach was severely distended with gas. Given a poor prognosis, the horse was euthanized on the table. At necropsy, the stomach appeared dilated, with an 180 horizontal gastric torsion, from left (lateral) to right (medial), dividing the organ into dorsal and ventral compartments. We believe that the chronic traction exerted by an incarcerated and distended loop of jejunum, in the dorsal aspect of the gastrosplenic ligament, associated with trauma during episodes of intense rolling, enlarged the rent until it ruptured. Because of this rupture, the lateral dorsal aspect of the stomach became unattached, predisposing it to the torsion. (C) 2012 Elsevier Inc. All rights reserved.

Fetal Pulmonary Response After Fetoscopic Tracheal Occlusion for Severe Isolated Congenital Diaphragmatic Hernia

OBJECTIVE: To estimate the response in lung growth and vascularity after fetal endoscopic tracheal occlusion for severe congenital diaphragmatic hernia in the prediction of neonatal survival. METHODS: Between January 2006 and December 2010, fetal lung parameters (observed-to-expected lung-to-head ratio; observed-to-expected lung volume; and contralateral lung vascularization index) were evaluated before fetal tracheal occlusion and were evaluated longitudinally every 2 weeks in 72 fetuses with severe isolated congenital diaphragmatic hernia. Thirty-five fetuses underwent fetal endoscopic tracheal occlusion and 37 cases did not. RESULTS: Survival rate was significantly higher in the fetal endoscopic tracheal occlusion group (54.3%) than in the no fetal endoscopic tracheal occlusion group (5.4%, P<.01). Fetal endoscopic tracheal occlusion resulted in a significant improvement in fetal lung size and pulmonary vascularity when compared with fetuses that did not go to the fetal intervention (increase of the observed-to-expected lung-to-head ratio, observed-to-expected total lung volume, and contralateral pulmonary vascularization index 56.2% compared with 0.3%, 37.9% compared with 0.1%, and 98.6% compared with 0.0%, respectively; P<.01). Receiver operating characteristic curves indicated that the observed-to-expected total fetal lung volume was the single best predictor of neonatal survival before fetal endoscopic tracheal occlusion (cutoff 0.23, area under the curve [AUC] 0.88, relative risk 5.3, 95% confidence interval [CI] 1.4-19.7). However, the contralateral lung vascularization index at 4 weeks after fetal endoscopic tracheal occlusion was more accurate in the prediction of neonatal outcome (cutoff 24.0%, AUC 0.98, relative risk 9.9, 95% CI 1.5-66.9) with the combination of observed-to-expected lung volumes and contralateral lung vascularization index at 4 weeks being the best predictor of outcome (AUC 0.98, relative risk 16.6, 95% CI 2.5-112.3). CONCLUSION: Fetal endoscopic tracheal occlusion improves survival rate by increasing the lung size and pulmonary vascularity in fetuses with severe congenital diaphragmatic hernia. The pulmonary response after fetal endoscopic tracheal occlusion can be used to predict neonatal survival. (Obstet Gynecol 2012; 119: 93-101) DOI: 10.1097/AOG.0b013e31823d3aea
