Full Text Available OBJECTIVE: Ventricular septal defects resulting from post-traumatic cardiac injury are very rare. Percutaneous closure has emerged as a method for treating this disorder. We wish to report our experience in three patients who underwent percutaneous closure of a post-traumatic ventricular septal defect with a patent ductus arteriosus occluder. METHODS: We treated three patients with post-traumatic ventricular septal defects caused by stab wounds with knives. After the heart wound was repaired, patient examinations revealed ventricular septal defects with pulmonary/systemic flow ratios (Qp/Qs of over 1.7. The post-traumatic ventricular septal defects were closed percutaneously with a patent ductus arteriosus occluder (Lifetech Scientific (Shenzhen Co., LTD, Guangdong, China utilizing standard techniques. RESULTS: Post-operative transthoracic echocardiography revealed no residual left-to-right shunt and indicated normal ventricular function. In addition, 320-slice computerized tomography showed that the occluder was well placed and exhibited normal morphology. CONCLUSION: Our experiences indicate that closure of a post-traumatic ventricular septal defect using a patent ductus arteriosus occluder is feasible, safe, and effective.

Traumatic neuroma is a well-known disorder that occurs after trauma or surgery involving the peripheral nerve and develops from a nonneoplastic proliferation of the proximal end of a severed, partially transected, or injured nerve. We present a case of traumatic neuroma around the celiac trunk after gastrectomy in a 56-year-old man, which was confirmed by pathology. CT demonstrated the presence of a lobulated, homogeneous, hypoattenuating mass around the celiac trunk, mimicking a nodal metast...

Traumatic neuroma is a well-known disorder that occurs after trauma or surgery involving the peripheral nerve and develops from a nonneoplastic proliferation of the proximal end of a severed, partially transected, or injured nerve. However, in the abdomen, traumatic neuromas have been sporadically reported to occur in the bile duct. We present here a case of traumatic neuroma around the celiac trunk after gastrectomy that mimicks a nodal metastasis. In conclusion, the imaging finding of traumatic neuroma around the celiac trunk was a homogeneous hypovascular mass without narrowing or irregularity of encased arteries and without increased uptake on PET-CT. Although from a clinical standpoint, establishing an accurate preoperative diagnosis is difficult to perform, the presence of a traumatic neuroma should be included in the differential diagnosis of a mass around the celiac trunk in a patient that has undergone celiac nodal dissection.

We report a very rare case of a congenital cervical spine anomaly. The low occurrence rate of this anatomic variant combined with the high frequency of cervical injuries in sports medicine made this case a diagnostic challenge on both emergency and orthopaedic departments. After reading, it should give the clinician a more consistent view in differentiating the traumatic or congenital origin of the disorder seen on radiographs, as well as what can be expected in the future when diagnosis is set.

Full Text Available Abstract Traumatic brain injury (TBI is a result of an outside force causing immediate mechanical disruption of brain tissue and delayed pathogenic events. In order to examine injury processes associated with TBI, a number of rodent models to induce brain trauma have been described. However, none of these models covers the entire spectrum of events that might occur in TBI. Here we provide a thorough methodological description of a straightforward closed head weight drop mouse model to assess brain injuries close to the clinical conditions of human TBI.
Aim: To present the imaging features of post-traumatic heterotopic ossification (HO) of the distal tibiofibular syndesmosis initially suspected to be a surface osteosarcoma. Materials and methods: A retrospective review was conducted of the presenting complaint and imaging features of patients with a final diagnosis of HO referred over an 8 year period to a specialist orthopaedic oncology centre. Results: Five patients with HO were identified. All were adult males with an age range of 19–41 years. There was a history of prior ankle trauma in all cases but the significance was not recognized at the time of referral to the specialist centre. There was radiographic evidence of HO arising from the inner aspects of the distal tibia and fibula approximately 3 cm proximal to the ankle joint. The HO was “kissing” in two cases and partially fused (synostosis) in two. The HO in the fifth case was arising on the inner fibular cortex alone. Magnetic resonance imaging (MRI), available in four cases, showed predominantly low signal intensity due to the dense bone formation. Conclusion: The history of prior ankle trauma with ossification arising from the inner aspects of both the distal tibia and fibula is typical of post-traumatic HO and distinguish this benign condition from the rare surface osteosarcoma at this site

We aimed to assess the state of the art of pharmacological treatment of patency of ductus arteriosus (PDA) with ibuprofen and paracetamol in preterm infants. We pointed out that ibuprofen is the first choice drug for PDA treatment and indomethacin should be abandoned for its frequent adverse effects. However, also the pharmacological prevention of PDA should be abandoned because many preterm infants have spontaneous closure of PDA and ibuprofen may have dangerous adverse effects. Oral paracet...

Patent ductus arteriosus (PDA) is a persistent patency of a vessel normally present in the fetus that connects the pulmonary arterial system to the aorta. The ductus arteriosus fails to close at birth when breathing commences and placental blood circulation is removed. Closure of the ductus arteriosus arises in response to decline pulmonary vascular resistance and increased systemic vascular resistance. This report describes a case of PDA in a two-month-old male lamb with clinical signs of machinery murmur, tachycardia, increase respiratory rate, weakness and ill thrift. Echocardiographic examination and necropsy finding confirmed PDA.

Objective: To determine the efficacy, safety and immediate complications encountered during percutaneous device closure of patent ductus arteriosus (PDA). Study Design: Case series. Place and Duration of Study: Department of Paediatric Cardiology, AFIC/NIHD, Rawalpindi, from January 2005 to December 2010. Methodology: Consecutive 500 patients who underwent attempted transcatheter PDA device closure were included in the study. Device type position, success of closure and complications were described as frequency percentage. Results: In 491 cases (98.2%), PDA was successfully occluded including 4 cases (0.8%) where devices were dislodged but retrieved and redeployed in Cath laboratory. PDA occluder devices used in 448 cases (91%) while coils (single or multiple) were used in 42 cases (8.5%) and in one case (0.2%) ASD occluder device was used to occlude the PDA. There were 09 (1.8%) unsuccessful cases, 06 (1.2%) were abandoned as ducts were considered unsuitable for device closure, 02 (0.4%) devices dislodged and needed surgical retrieval and one case (0.2%) was abandoned due to faulty equipment. The narrowest PDA diameter ranged from 0.5 - 14 mm with mean of 4.5 +- 2.4 mm. There was a single (0.2%) mortality. Conclusion: Transcatheter occlusion of PDA by coil or occluder device is an effective therapeutic option with high success rate. Complication rate is low in the hands of skilled operators yet paediatric cardiac surgical back-up cover is mandatory. (author)

To investigate the mechanism underlying irreversibility of ductal closure after birth, studies were undertaken to determine the exact time course for the onset of irreversible closure of the guinea pig ductus arteriosus. Parallel studies of the reactivity of ductal smooth muscle to oxygen and studies of the postpartum cellular changes within the vessel were also carried out.
Targeted milrinone treatment for low left ventricular output (LVO) reduces the incidence of acute cardiorespiratory instability following ligation of patent ductus arteriosus (PDA) in preterm infants. Despite this, some infants continue to experience postoperative deterioration. Adrenal insufficiency related to prematurity has been postulated as a possible mechanism.

A 10-year-old girl with a diagnosis of patent ductus arteriosus from the time of birth was noted to have disappearance of her typical continuous murmur on two separate, well-documented occasions. Cardiac catheterization showed a small patent ductus arteriosus with a pulmonic/systemic flow ratio of 1.3:1. Conservative treatment was advised. Twelve other cases of intermittent disappearance of the murmur of a patent ductus arteriosus were found in the literature.

Ductus arteriosus and foramen ovale were described by Galen without understanding their functions. His beliefs in soul localization and spiritization within the left ventricle established religious pneumatology which became a theological need in the Middle Ages. Pulmonary transit was recognized by Servetus and Colombo after the Reformation around 1550. This prompted Harvey's full understanding of the fetal circulation. Botallo did not describe the ductus arteriosus, but in 1564 redescribed the foramen ovale, making his way into the nomina anatomica by mistake. Most authors of the 19th and 20th century believed ductal patency to be passive, and postnatal closure to be an active process, explained by mechanical theories. After the discovery of prostaglandins by Bergstrom and Vane, Coceani proved that ductal patency is maintained by the relaxant action of prostaglandins. PMID:20639680

This report describes a rare case of chronic osteomyelitis in a 60 year old man mimicking a soft tissue sarcoma. Chronic osteomyelitis is an infrequent cause of a soft tissue mass and is usually diagnosed clinically by a combination of radiology and microbiology. Rarely, COM can mimic a primary bony neoplasm, but this is the first reported case where it mimicked a soft tissue sarcoma. The clinical, radiological, and histological appearances of this case will be discussed.
Background: Patent Ductus Arteriosus (PDA) is developing as major problem in our society. Many studies in Pakistan has been done to analyze the efficacy of surgical procedures but no one tried to find the frequency of factors leading to this problem. Objective: The purpose of this study was to find out the frequency of factors leading to patent ductus arteriosus in children presented at Punjab Institute of Cardiology. Method: A cross sectional study was conducted on 242 patients of PDA who already have been treated during the year 2006 - 2007. They were interviewed on their regular follow up visits. Their operative information was gathered from their files. Results: Mean age of children at time of treatment was 6.12 + 5.203 years. Out of 242 children, there were more female (62.8%) as compared to male (37.2%). In this study, 17.8% children inherited the disease from their close relatives and 105 (43.4%) mothers had some infectious problems during pregnancy. 103 (42.6%) mothers used antibiotics or other drugs during pregnancy. 11 (4.5%) children had Down syndrome. One hundred and thirty seven (56.61%) children had premature birth. Conclusion: Female gender, preterm birth, infection during pregnancy, mother's exposure to drugs and smoking, low birth weight may be etiological factors for development of PDA. (author)

An aneurysm of the ductus arteriosus is a rare finding, particularly in the adult population. These saccular aneurysms arise at the site of an incompletely obliterated ductus arteriosus along the lesser curvature of the aortic arch. Left untreated, it is associated with a high risk of potentially life-threatening complications including rupture, infection and thromboembolism. As a result, surgical correction is recommended. Previously, options were limited to open repair but as endovascular experience grows, novel techniques afford safer and less invasive alternatives. In contrast, neonatal ductus arteriosus aneurysms may regress spontaneously and expectant treatment can be justified. We present the case of a 74-year-old woman who presented with hoarseness secondary to a ductus arteriosus aneurysm; a diagnosis consistent with Ortner's syndrome. The patient underwent an uncomplicated endovascular repair using the chimney-graft technique. PMID:27141045

Interruption of the aortic arch is a rare congenital disease. It is defined by the complete interruption between the ascending and descending aorta. A patent ductus arteriosus is necessary to maintain flow from the pulmonary to the descending aorta. Its closure leads to a cardiovascular collapse and this malformation is therefore duct-dependent. However, in rare cases, survival remains possible even after ductus arteriosus closure. We report such a case. PMID:24457106

Acute urticaria is a self-limited cutaneous condition marked by transient, erythematous, and pruritic wheals. It is a hypersensitivity response that is often secondary to infection, medications, or food allergies in children. In contrast, the urticarial "mimickers" described in this review article are often seen in the context of fever and extracutaneous manifestations in pediatric patients. The differential diagnosis ranges from benign and self-limited hypersensitivity responses to multisystem inflammatory diseases. Establishing the correct diagnosis of an urticarial rash in a pediatric patient is necessary to both prevent an unnecessary work up for self-limited conditions and to appropriately recognize and evaluate multisystem inflammatory disorders. Herein, we describe two cases to illustrate the clinical manifestations, laboratory findings, histopathology and differential diagnoses for several mimickers of acute urticaria including: urticaria multiforme, serum sickness like reaction, Henoch-Schönlein purpura, acute hemorrhagic edema of infancy, systemic onset juvenile idiopathic arthritis, cryopyrin associated periodic syndromes, and urticarial vasculitis.

Full Text Available Aim: To compare brain natriuretic peptide level and some of the echocardiographic parameters of premature infants and to search its value for the diagnosis of patent ductus arteriosus.Material and Method: Fifty infants born before the 34th gestational week in the neonatology clinic of Bakırkoy Obstetrics and Children’s Educational Hospital between March 2009 and August 2009 were inspected prospectively. Patients with patent ductus arteriosus constituted Grup 1 (n=20 and patients without patent ductus arteriosus constituted Grup 2 (n=30. The diagnosis of patent ductus arteriosus was made by M-mode and Doppler echocardiography on the 7th day postnatally. Ductus diameter, left atrium aortic root diameter ratio, left ventricular end diastolic diameter, interventricular septum thickness, left ventricular posterior wall thickness, ejection fraction and fractional shortening were evaluated. The infants with hemodynamically significant patent ductus arteriosus were treated.Brain natriuretic peptide was evaluated on the 1st, 3rd and 7th days of postnatal age in all patients and also on the 3rd day after treatment. For statistical analysis SPSS for Windows 15.0 was used. The study was conducted after obtaining informed consent from the patients and was approved with the decision of the ethics commitee (number 231, date 12-6-2009. Results: Sex, gestational age and birth weight were similar in both grups. When brain natriuretic peptide level was compared with ductus diameter, left atrium aortic root diameter ratio and left ventricular end diastolic diameter values, the results were found to be statistically significant (p0.05. Brain natriuretic peptide level decreased significantly after treatment.Conclusions: Brain natriuretic peptide level was found be higher in infants with patent ductus arteriosus compared to infants without patent ductus arteriosus. It was shown that ductus diameter, left atrium aortic root diameter ratio and left ventricular end

Dynamic images and curves obtained from radioisotopic angiocardiography (RI-ACG) using video recording system were studied in 5 patients with patent ductus arteriosus (PDA), to disclose any characteristic findings of PDA on this radioisotopic examination. And, the examination was evaluated with referance to diagnosis and assessment of status of PDA, comparing with other radiological examinations including angiocardiography and catheterization. Both the dynamic images and the dynamic curves of RI-ACG showed some characteristic findings of PDA, which was considered to be valuable to differentiate the intracardiac left to right shunt in atrial or ventricular septal defect. It was very characteristic of PDA that dynamic images showed regional dilution and recirculation patterns in the region of the main pulmonary artery to its periphery, and dynamic curves presented shunt waves on the descending limbs of the first circulation waves of both the pulmonary and the left ventricular region of interest. The Degrees of appearance of these characteristic findings showed a tendency to well correlate with the value of the left to right shunt fraction calculated by cathetelization technique. On the other hand, RI-ACG showed useful findings to diagnose pulmonary hypertension or heart failure associated with PDA. And, RI-ACG was very useful to detect an abrupt change of the central circulation dynamics in a patient with PDA, in whom continuous murmur characteristic of PDA desappeared intermittently. (author)

Primary hyperoxaluria is a rare hereditary metabolic disorder resulting in accumulation of calcium oxalate in visceral organs, including the heart. We report a 19-year-old male with non- compaction cardiomyopathy combined with patent ductus arteriosus awaiting combined liver-kidney transplantation for primary hyperoxaluria. After surgical closure of the patent ductus arteriosus, the patient underwent a successful renal and subsequent liver transplantation. The presence of hypertrophic cardiomyopathy in hyperoxaluria patients has been reported before, but this is the first report of non-compaction myocardium with patent ductus arteriosus in a patient with primary hyperoxaluria. At the third month after combined liver and renal transplantation, improvement in cardiac functions were observed. Primary hyperoxaluria is a clinical entity to be taken into consideration in differential diagnosis of hypertrophied myocardium with high myocardial echocardiographic intensity. In cases of hyperoxaluria, additional congenital abnormalities may complicate the clinical picture. PMID:25906003
Full Text Available Purpose: The purpose of this study was to share our experience of transcatheter closure of small patent ductus arteriosus (PDA by using an Amplatzer vascular plug (AVP.<br> Methods: We reviewed the medical records of 20 patients who underwent transcatheter closure at Samsung Medical Center and Sejong General Hospital from January 2008 to August 2012. The size and shape of the PDAs were evaluated by performing angiograms, and the PDA size and the AVP devices size were compared.<br>Results: The mean age of the patients was 54.9±45.7 months old. The PDAs were of type C (n=5, type D (n=12 and type E (n=3. The mean pulmonary end diameter of the PDA was 1.7±0.6 mm, and the aortic end diameter was 3.6±1.4 mm. The mean length was 7.3±1.8 mm. We used 3 types of AVP devices: AVP I (n=5, AVP II (n=7, and AVP IV (n=8. The ratio of AVP size to the pulmonary end diameter was 3.37±1.64, and AVP size/aortic end ratio was 1.72±0.97. The aortic end diameter was significantly larger in those cases repaired with AVP II than in the others (P =0.002. The AVP size did not significantly correlate with the PDA size, but did correlate with smaller ratio of AVP size to aortic end diameter (1.10±0.31, P =0.032. <br>Conclusion: Transcatheter closure of small PDA with AVP devices yielded satisfactory outcome. AVP II was equally effective with smaller size of device, compared to others.

Full Text Available Introduction: Transcatheter closure is a treatment choice for the most children with patent ductus arteriosus (PDA. The closure of the ductus is indicated in any child or adolescent with developed symptoms of significant L-R shunt. The aim of this article is to present our results in 5 years treatment of patients with PDA and their outcome. Methods: From 2009 to 2014, 30 patients underwent a transcatheter closure of PDA at Centre for Heart and Pediatric clinic of Clinical University Centre of Sarajevo. Aortic angiogram was performed to evaluate the size, position, and shape of the duct for selection of appropriate occluder device type and size. All procedures were performed by local team of cardiologists from the Department of Cardiology, Pediatric clinic, with invasive cardiologists team from Sweden and Austria. Echocardiography was repeated at intervals of 24 hours, then 1month, 3 months, and 1 year after the procedure to assess the outcome. Results: Thirty patients underwent transcatheter closure of PDA during the study period. PDA of ≤ 2.0 mm was present in 8 patients and they underwent PDA closure with coils, while 22 patients had PDA diameter ≥ 2 mm, and they were treated by Amplatzer duct occluder (ADO. Only in 2 (6.2% patients complications have been observed. The length of hospital stay after the treatment was two to three days. Conclusion: Transcatheter closure of PDA is a modern, safe and efficient method that ensures a faster recovery of the patients, shortens the length of hospitalization.
Ductal stenting is an attractive alternative to conventional shunt surgery in duct dependent congenital heart disease as it avoids thoracotomy and its related problems. With today's generation of coronary stents which have better profile, flexibility and trackability, ductal stenting may be achieved safely and with considerably less difficulty than previously described. As in Blalock-Taussig (BT) shunt, ductal stenting is indicated mainly in duct-dependent cyanotic lesions chiefly in the neonatal period. Unlike the Patent ductus arteriosus (PDA) as an isolated lesion, the ductus in cyanotic heart disease has a remarkable morphologic variability. The ductus tends to arise more proximally under the aortic arch, giving rise to a vertical ductus or occasionally it may arise from the subclavian artery. It also tends to be long and sometimes very tortuous, rendering stent implantation technically impossible. The ductus in these patients may also insert onto one of the branch pulmonary arteries with some stenosis at the site of insertion. The ductus in Tetralogy of Fallot with pulmonary atresia (TOF-PA) tend to exhibit these morphologic features and to a lesser degree in transposition of great arteries with ventricular septal defect and pulmonary atresia (TGA-VSD-PA) and the more complex forms of univentricular hearts. In the preliminary angiographic evaluation, it is important to delineate these morphologic features as the basis for case selection. Ductal stenting may be done by the retrograde femoral artery route or the antegrade transvenous route depending on the ductus morphology and the underlying cardiac lesion. The detailed techniques and essential hardware are described. Finally, major potential complications of the procedure are described. Acute stent thrombosis is the most serious and potentially catastrophic. Emergent treatment with thrombolytic therapy and mechanical disruption of thrombus are required. With proper case selection, appropriate technique
3-D CT angiographic demonstration of a neonatal ductus arteriosus aneurysm with development of ductal calcification: are the ''ductus bump'', ductus arteriosus aneurysm, and ductal calcification related?
A ''ductus bump'' was noted as an incidental finding on a chest radiograph in a newborn infant with congenital cystic adenomatoid malformation. A chest CT performed on the first day of life demonstrated this to be a ductus arteriosus aneurysm (DAA), which subsequently thrombosed. Ductal calcification was noted on follow-up imaging. We propose that the ''ductus bump'' may actually be a DAA, which resolves presumably by thrombus formation. Ductal calcification may also be related to the regression of the thrombus. (orig.)

We prospectively studied the effect of oral paracetamol in closing hemodynamically significant Patent ductus arteriosus in preterm infants (gestational age <32 weeks) where Ibuprofen was contraindicated. 29 of 40 neonates (72.5%) showed successful response while 11 (29.5%) failed to show any response. No major complications were seen. PMID:26897160
Patent ductus arteriosus (PDA) is one of the most common congenital heart diseases. A rare complication occurring after its surgical treatment is the development of an aneurysm, and we report the radiologic findings in a case in which this occurred after surgical ligation
Objective: To evaluate the efficacy and safety of emergency transcatheter occlusion of patent ductus arteriosus associated with severe pneumonia in infants. Methods: During the period from Oct. 2011 to May 2012, 12 infants with patent ductus arteriosus complicated by severe pneumonia were admitted to the hospital. The infants had repeated episodes of pneumonia together with heart failure. Emergency transcatheter occlusion of patent ductus arteriosus was carried out in all infants. After the treatment the use of anti-bacterial drugs and cardiac stimulants was kept on. Routine examinations of blood and urine were made 24 hours after the management. Two-dimensional and color Doppler echocardiography, chest radiograph and electrocardiogram were performed at 24 hours, 1, 3, and 6 months after the surgery. The results were analyzed. Results: After emergency transcatheter closure, all patients recovered fully at the time of discharge. No intervention-related major complications occurred during short-term follow-up period. Conclusion: For the treatment of patent ductus arteriosus associated with severe pneumonia in infants, emergency transcatheter occlusion therapy is effective and safe. Optimal surgery time together with proper perioperative management is the key to ensure a successful operation. (authors)

@@ Patent ductus arteriosus (PDA) device closure was first attempted by Porstmann et al1 in 1967. Due to the rapid development in this field, it is the therapy of choice in current era. As most of PDAs have conical shape, Amplatzer PDA occluders were designed to fit into these ducts.

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether thoracoscopic patent ductus arteriosus (PDA) closure is superior to conventional surgery. Altogether 821 papers were found using the reported search, 11 of which represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Eleven studies included in the analysis consisted of two prospective and three retrospective, non-randomized studies and six case series. Four included studies focused only on preterm infants, three studies enrolled neonates and the other four analysed all age groups from neonates to older children or young adults. There were no differences in mortality between video-assisted thoracoscopic surgery (VATS) and conventional surgery. Two studies suggested that VATS offers shorter operative times. Two papers observed shorter hospital stay, although the other two noted no significant difference. A large prospective trial found VATS to be associated with a lower number of postoperative complications in neonates and infants, whereas other studies suggested no significant differences in short-term postoperative complications. There is little evidence to suggest better musculoskeletal status and cosmesis in neonates following VATS. Conversion from thoracoscopy to thoracotomy described in six papers was seldom and it did not lead to any additional complications. All observational studies confirmed that both techniques are free from major adverse cardiovascular complications and these two techniques can be safely used in all patients qualified for surgical PDA closure. Two studies compared cost-effectiveness between the two techniques; one of them described VATS as significantly more cost-efficient, whereas the other study observed no difference. However, it should be noted that data

Sex hormones have an important influence on cardiovascular physiology and pathophysiology and sex differences in vascular reactivity have been widely demonstrated. In the present study we hypothesized 1) the presence of sexual dimorphism in chicken ductus arteriosus (DA) responsiveness to contractile and relaxant stimuli and 2) that estrogens are vasoactive in the chicken DA. In vitro contractions (assessed with a wire myograph) induced by normoxia, KCl, 4-aminopyridine, norepinephrine, phenylephrine, U46619, or endothelin-1, as well as relaxations induced by ACh, sodium nitroprusside, BAY 41-2272, PGE(2), isoproterenol, forskolin,Y-27632, and hydroxyfasudil were not significantly different between males and females. The estrogen 17beta-estradiol elicited concentration-dependent relaxation of KCl-, phenylephrine-, and oxygen-induced active tone in male and female chicken DA. The stereoisomer 17alpha-estradiol showed lesser relaxant effects, and the selective estrogen receptor (ER) agonists 4,4',4''-(4-propyl-[(1)H]pyrazole-1,3,5-triyl)tris-phenol (ERalpha) and 2,3-bis(4-hydroxyphenyl)-propionitrile (ERbeta) did not show any effect. There were no sex differences in the responses to estrogen. Endothelium removal or the presence of the soluble guanylate cyclase inhibitor ODQ, the K(+) channel blockers tetraethylammonium, glibenclamide, and charybdotoxin, or the ER antagonist fulvestrant did not modify 17beta-estradiol-induced relaxation. CaCl(2) (30 muM-10 mM) induced concentration-dependent contraction in DA rings depolarized by 62.5 mM KCl or stimulated with 21% O(2) in Ca(2+)-free medium. Preincubation with 17beta-estradiol or the L-type Ca(2+) channel blocker nifedipine produced an inhibition of CaCl(2)-induced contractions. In conclusion, there are no sex-related differences in chicken DA reactivity. The estrogen 17beta-estradiol induces an endothelium-independent relaxation of chicken DA that is not mediated by ER activation. This relaxant effect is, at least

Full Text Available Introduction: Truncus arteriosus with intact ventricular septum is a rare and unique variant of persistent truncus arteriosus (PTA which usually presents with central cyanosis and congestive heart failure in neonate and early infancy. Associated cardiac and non-cardiac anomalies may affect morbidity and mortality of these patients. Case Presentation: We describe clinical presentation, echocardiography and angiographic features of a 7-month old boy with PTA and intact ventricular septum who underwent surgical repair of the anomaly at our institution. Operative findings, surgical procedure and short-term outcome are reported. Conclusions: While our patient had systemic pulmonary arterial pressure at the time of complete surgical repair, it was improved after surgery.

Ibuprofen-induced ductus closure improves pulmonary mechanics and increases alveolar surface area in premature baboons compared with baboons with a persistent patent ductus arteriosus (PDA). Ibuprofen-treatment has no effect on the expression of genes that regulate pulmonary inflammation but does increase the expression of alpha-ENaC (the transepithelial sodium channel that is critical for alveolar water clearance). Although ligation eliminates the PDA, it does not improve pulmonary mechanics...

A persistent left-to right shunt through a patent ductus arteriosus (PDA) increases the rate of hydrostatic fluid filtration into the lung’s interstitium, impairs pulmonary mechanics, and prolongs the need for mechanical ventilation. In preclinical trials, pharmacologic PDA closure leads to improved alveolarization and minimizes the impaired postnatal alveolar development that is the pathologic hallmark of the “new bronchopulmonary dysplasia (BPD)”. Although early pharmacologic closure of the...
Full Text Available Abstract Background The patent ductus arteriosus (PDA is an important problem in premature infants. Surgical PDA ligation is usually only be considered when medical treatment has either failed or was contraindicated. The aims of our study were to determine the mortality and morbidity following patent ductus arteriosus ligation in premature infants, and whether prostaglandin synthetase inhibitor (PSI use prior to ligation affects outcome. Methods A retrospective case note review study to determine the outcome of premature infants undergoing patent ductus arteriosus ligation in one tertiary neonatal intensive care unit and two paediatric cardiothoracic centres. Results We had follow-up data on 87 infants. Cumulative mortality rates at 7 days, 30 days and at hospital discharge were 2%, 8% and 20% respectively. The incidence of chronic lung disease, intraventricular haemorrhage, necrotising enterocolitis and retinopathy of prematurity were 77%, 39%, 26% and 28% respectively. There was no difference in mortality, incidence of chronic lung disease or duration of oxygen dependence between those who had and those who had not received a PSI prior to surgical ligation. In those who had received 2 or more courses of PSI prior to surgical ligation, there was a trend to increase in the duration of oxygen therapy and chronic lung disease, but no difference in mortality. Conclusion This study shows that patent ductus arteriosus ligation is a relatively safe procedure (30 day survival 92% but there is substantial late mortality and a high incidence of morbidity in the survivors. 2 or more courses of PSI prior to surgical ligation trends to increased oxygen dependence and chronic lung disease. This high risk population requires careful follow-up. A definitive prospective cohort study is lacking.

The association between large, left-sided patent ductus arteriosus and severe, peripheral, right pulmonary artery stenosis with no other cardiac malformation is an unreported condition that might be misdiagnosed as pulmonary hypertension due to long-standing ductal shunt. A 57-year-old man with supposed hypertensive patent ductus arteriosus underwent confirmatory cardiac catheterization. At angiography, a severe pre-hilar right pulmonary artery stenosis (peak pressure gradient, 65 mmHg) was found to complicate the hemodynamic picture of a moderate-to-large patent ductus arteriosus (QP/QS, 1.7:1), by causing pulmonary hypertension (mean pressure, 65 mmHg) and left-to-right pulmonary flow imbalance. Both lesions were treated in a single procedure of right pulmonary artery stenting and patent ductus arteriosus closure, after which the pulmonary artery pressure significantly decreased (mean, 35 mmHg). In our opinion, a thorough hemodynamic evaluation followed by pulmonary angiography should be mandatory before proceeding to patent ductus arteriosus closure in the adult patient who has “hypertensive” ductus, in whom possible associated malformations can be missed due to a poor echocardiographic window.

Full Text Available The diagnosis of hepatocellular carcinoma (HCC became easier in relation to the improved radiological examinations; however, the neoplasm may occur under atypical presentations mimicking other benign or malignant processes. Multicystic HCC mimicking a liver abscess associated with septic-type fever and leukocytosis is rare, has a poor prognosis, and poses diagnostic and therapeutic dilemmas. We present the case of an 80-year-old patient, who presented with fever, leukocytosis, and large cystic masses involving right and left lobes of the liver initially considered abscesses and finally diagnosed as HCC after open drainage and liver biopsy. Although the patient died on the tenth postoperative day due to pulmonary oedema, the authors emphasize the high index of suspicion needed in the diagnosis of this unusual presentation of HCC.

Full Text Available Background Indomethacin and ibuprofen are anti-prostaglandin E2 agents administered for persistent ductus arteriosus (PDA closure. Ibuprofen has weaker cyclooxygenase-1 inhibitor affinity than that of indomethacin, causes decreased gastrointestinal circulation, as well as brain and kidney side effects. Objective To compare the efficacy of oral ibuprofen and indomethacin for PDA closure in preterm infants. Methods A randomized double-blind controlled trial on preterm infants with PDA was performed in Moehammad Hoesin Hospital, Palembang, from October to December 2011. Persistent ductus arteriosus was diagnosed by echocardiography. Subjects were divided into two groups, and received either ibuprofen or indomethacin. Ibuprofen was given at a dose of 10 mg/kgBW/d on day 1 and 5 mg/kgBW/d on days 2 and 3. Indomethacin was given in three doses over 24 hour-intervals; the first dose was 0.2 mg/kg, and the second and third doses were 0.1 mg/kg each. Results Sixty infants were enrolled in this study, 36 boys (60% and 24 girls (40%. Fifty-two subjects completed the study protocol. Ductus arteriosus (DA closure after treatment was observed in 22 out of 26 subjects in the ibuprofen group and 19 out of 26 subjects in the indomethacin group (P=0.04. The mean DA diameter reductions after administration of ibuprofen or indomethacin were 0.40 (SD 0.16 mm and 0.30 (SD 0.21 mm, respectively (95%CI of differences 0.05 to 0.17; P=0.04. Serum creatinine was elevated in the indomethacin group following treatment compared to the ibuprofen group [P = 0.002, 95% CI of differences 0.06 to 0.27]. Ductus arteriosus reopening occurred in 4 out of 19 subjects in the indomethacin group, while none in the ibuprofen group. Conclusions Ibuprofen is better than indomethacin, in terms of higher PDA closure rate and mean DA diameter reduction after treatment. In additional, indomethacin has significantly greater increase in mean serum creatinine level after treatment than ibuprofen

In elderly patients, open surgery for patent ductus arteriosus (PDA) is more difficult than that in children and often requires a cardiopulmonary bypass. We report the case of a 67-year-old patient with a PDA that was successfully treated with thoracic endovascular aortic repair (TEVAR). The patient was diagnosed with congestive heart failure (ejection fraction, 36 %) and PDA (9.7 mm in diameter). TEVAR was successfully performed to exclude the PDA. After TEVAR, the patient's heart failure was well controlled by diuretics. TEVAR may be a good alternative to open surgery. PMID:25056455

We describe a case of a 21-year-old primigravida at 36 weeks' gestation who was admitted to a local hospital because of abdominal pain. She was prescribed a total of six doses of diclofenac 50 mg over 2 days. One day later, there was difficulty registering the fetal heartbeats on cardiotocography. Ultrasound examination revealed a fetus with ascites and pathological flow over the tricuspid valve. The patient was referred to a tertiary centre for fetal medicine. Fetal echocardiography revealed, in addition to ascites and tricuspid regurgitation, a constricted ductus arteriosus, dilated right ventricle and reduced flow in the pulmonary artery. Immediate caesarean section resulted in an excellent neonatal outcome. PMID:26427495

Despite a large body of scientific evidence on the management of premature infants with a patent ductus arteriosus controversy remains and neonatologists remain challenged for knowing which patient to treat, what is the most optimal timing of treatment and which treatments have a positive impact on both short-term and long-term outcomes. In this review article we discuss the increased body of evidence over the past 10 years, much of which questions the role of treatment and suggests the need to reconsider how haemodynamic significance is adjudicated. In addition, we discuss novel approaches to assessment and diagnosis, and highlight areas for future investigation. PMID:27118761
Over the past decade, video-assisted thoracoscopic techniques have been used in the pediatric population. Recently, the computer-enhanced robotic system has been applied to video-assisted thoracoscopic interruption of patent ductus arteriosus (VATS-PDA). We focused on the utility of a voice-controlled robotic arm (automated endoscope system for optimal positioning: AESOP 3000) in VATS-PDA. Thirteen infants weighing 4.2 approximately 12.6 (mean 6.6) kg underwent robotically assisted VATS-PDA. Robotically assisted VATS-PDA is comparable with closure by means of the conventional video-assisted thoracoscopic technique. PMID:16910511

Truncus arteriosus is an uncommon congenital cardiac abnormality which is characterized by a single arterial trunk origin from the heart that supplies both the systemic,pulmonary and coronary circulation.We present a preterm newborn female patient with type 2 truncusarteriosus,left superior vena cava and aberrant subclavian artery diagnosed with low dose dual-source cardiac computed tomography(CT).We discuss that low dose dual-source cardiac CT has more advantages than other imaging methods and it is an important modality for assessment of patients with conotruncal anomalies such as truncusarteriosus.
Full Text Available This is the case of a young female who was seen at our adult congenital heart disease and pulmonary hypertension service (Royal Brompton Hospital, London, UK at the age of 17 years. She initially presented at the age of 4 years with increasing shortness of breath. At that time, there was differential cyanosis with clubbing and lower oxygen saturations in the toes (82% compared with her fingers (95%. On echocardiography there was evidence of severe pulmonary hypertension and a large patent ductus arteriosus (PDA with low velocity bidirectional shunting. She underwent cardiac catheterisation at the time which showed a pulmonary arterial pressure equal to that of the aorta.

Complex congenital heart disease with pulmonary atresia is ductus arteriosus-dependent. Two palliative treatments have been available for years: a systemic pulmonary shunt and prostaglandin E1 infusion. Recently, interventional cardiology has offered a new procedure for these patients: stenting of the patent arterial duct. We report a case with univentricular heart and pulmonary atresia in which percutaneous balloon angioplasty and stenting of the arterial ductus were performed successfully. Nineteen months later the patient is in good clinical conditions with 75% of oxygen saturation. PMID:12148334

Full Text Available Truncus arteriosus (TA is a rare congenital heart disease defined as a single arterial vessel arising from the heart that gives origin to the systemic, pulmonary and coronary circulations. The truncal valve in majority of the cases is tricuspid though quadricuspid and bicuspid valves have been reported. Patients with TA typically have a large nonrestrictive sub truncal ventricular septal defect. Survival of these infants beyond 1-year is uncommon. Here, we report a unique case of 12-year-old female patient with persistent TA who underwent surgical repair by using transesophageal echocardiography as a monitoring device during the perioperative management.
Full Text Available Although the prophylactic administration of indomethacin in extremely low-birth weight infants reduces the frequency of patent ductus arteriosus and severe intraventricular hemorrhage, it does not appear to provide any long-term benefit in terms of survival without neurosensory and cognitive outcomes. Considering the increased drug-induced reduction in renal, intestinal, and cerebral blood flow, the use of prophylaxis cannot be routinely recommended in preterm neonates. However, a better understanding of the genetic background of each infant may allow for individualized prophylaxis using NSAIDs and metabolomics.

Full Text Available Patent ductus arteriosus (PDA is a common congenital heart disease, accounting for 5-10% of all congenital heart diseases. The incidence of PDA is even higher in preterm neonates, ranging from 20-60%.1-4 Closure of PDA is indicated in all cases, except for duct-dependent congenital heart diseases or PDA with Eisenmenger syndrome.1,5,6 In small asymptomatic PDAs, closure is indicated to prevent the risk of complications, such as endarteritis, endocarditis, aneurysm of ductus arteriosus, or congestive heart failure.1,2,7 In recent years, interventional cardiology has become a gold standard therapy for the majority of PDA cases beyond neonatal age. Since its introduction in 1967, many devices and methods have been developed to allow transcatheter closure of virtually all PDAs, regardless of size or configuration. Nevertheless, the tubular shape (type C PDA, which has the highest residual shunt rate, still poses a great challenge for the interventionist.8-10 The second generation of Amplatzer® device occluders (ADO II, released in 2007, has been suggested to be effective in closing tubular PDAs.10 The purpose of this study was to report the initial clinical experience using ADO II to close a tubular type PDA in Indonesia

Nonsyndromic patent ductus arteriosus (PDA) is a common congenital heart defect (CHD) with both inherited and acquired causes, but the disease mechanisms have remained elusive. Using combined genome-wide linkage analysis and whole-exome sequencing (WES), we identified independent mutations in PRDM6, which encodes a nuclear protein that is specific to vascular smooth muscle cells (VSMC), has histone methyl transferase activities, and acts as a transcriptional suppressor of contractile proteins. In vitro assays showed that the mutations cause loss of function either by intracellular redistribution of the protein and/or by alteration of its methyltransferase activities. Wild-type embryonic ductus arteriosus (DA) exhibited high levels of PRDM6, which rapidly declined postnatally as the number of VSMCs necessary for ductus contraction increased. This dynamic change suggests that PRDM6 plays a key role in maintaining VSMCs in an undifferentiated stage in order to promote their proliferation and that its loss of activity results in premature differentiation and impaired remodeling of the DA. Our findings identify PRDM6 mutations as underlying genetic causes of nonsyndromic isolated PDA in humans and implicates the wild-type protein in epigenetic regulation of ductus remodeling.

Endovascular stent graft implantation is a favorable method for complex aortic coarctation accompanied by patent ductus arteriosus. Herein, an 18-year-old woman with complex aortic coarctation and patent ductus arteriosus was successfully treated by endovascular thoracic stent graft via retroperitoneal approach. The reason for retroperitoneal iliac approach was small sized common femoral arteries which were not suitable for stent graft passage. This case is the first aortic coarctation plus patent ductus arteriosus case described in the literature which is treated by endovascular thoracic stent graft via retroperitoneal approach.

Traumatic Brain Injury (TBI) is among the most frequent neurological disorders. Of all TBIs 90% are considered mild with an annual incidence of 100-300/100.000. Intracranial complications of Mild Traumatic Brain Injury (MTBI) are infrequent (10%), requiring neurosurgical intervention in a minority o
Black hole mimickers are possible alternatives to black holes; they would look observationally almost like black holes but would have no horizon. The properties in the near-horizon region where gravity is strong can be quite different for both types of objects, but at infinity it could be difficult to discern black holes from their mimickers. To disentangle this possible confusion, we examine the near-horizon properties, and their connection with far away asymptotic properties, of some candidates to black mimickers. We study spherically symmetric uncharged or charged but nonextremal objects, as well as spherically symmetric charged extremal objects. Within the uncharged or charged but nonextremal black hole mimickers, we study nonextremal ε-wormholes on the threshold of the formation of an event horizon, of which a subclass are called black foils, and gravastars. Within the charged extremal black hole mimickers we study extremal ε-wormholes on the threshold of the formation of an event horizon, quasi-black holes, and wormholes on the basis of quasi-black holes from Bonnor stars. We elucidate whether or not the objects belonging to these two classes remain regular in the near-horizon limit. The requirement of full regularity, i.e., finite curvature and absence of naked behavior, up to an arbitrary neighborhood of the gravitational radius of the object enables one to rule out potential mimickers in most of the cases. A list ranking the best black hole mimickers up to the worst, both nonextremal and extremal, is as follows: wormholes on the basis of extremal black holes or on the basis of quasi-black holes, quasi-black holes, wormholes on the basis of nonextremal black holes (black foils), and gravastars. Since in observational astrophysics it is difficult to find extremal configurations (the best mimickers in the ranking), whereas nonextremal configurations are really bad mimickers, the task of distinguishing black holes from their mimickers seems to be less
A 4-month-old female mongrel puppy was presented with an anophthalmos. On physical examination, systolic murmur was heard at the 4th left intercostal space near the sternum. However the dog appeared healthy without cyanosis and had no history of exercise intolerance. The phonocardiogram revealed a pansystolic murmur and a continuous murmur on the mitral area. A systolic ejection murmur was also recorded on the pulmonic area. The electrocardiogram indicated bi-ventricular hypertrophy. Left ventricular enlargement was seen on chest radiographs. Ventricular septal defect (VSD) and patent ductus arteriosus (PDA) were diagnosed from these findings. PDA closure was performed at 2 years of age. After 2 months from the operation, the dog died during an attempted repair of the VSD. At necropsy, it was found that the double-chambered right ventricle (DCRV) was formed by an anomalous septal band. The VSD was localized on the proximal conus and was 8 mm in diameter. (author)

Results: There were 16 newborns in each group (20 boys and 12 girls. In 12 newborns of prophylaxis group the ductus arteriosus was closed although in control group in 8 newborns the duct was closed. No significant difference was observed in sex, gestational age, birth weight, mode of delivery, multifetal gestation and birth order between two groups. The rate of ductal closure was 75% and 50% in prophylaxis group and control group respectively (P=0.27. Conclusion: Our study demonstrated that prophylactic paracetamol is ineffective in PDA closure, although the rate of ductal closure between two groups seems remarkable. Paracetamol as a new strategy for PDA closure because of cost effectiveness and harmlessness may be used in future. However, we presume larger sample size studies are needed to show the efficacy of paracetamol, side effects, and complications in PDA prophylaxis treatment.

Infective endocarditis (IE) in dogs with cardiac shunts has not been reported previously. However, we encountered a dog with concurrent patent ductus arteriosus (PDA) and IE. The dog was a 1-year-old, 13.9-kg female Border collie and presented with anorexia, weight loss, pyrexia (40.4 °C) and lameness. A continuous murmur with maximal intensity over the left heart base (Levine 5/6) was detected on auscultation. Echocardiography revealed a PDA and severe aortic stenosis (AS) caused by aortic-valve vegetative lesions. Corynebacterium spp. and Bacillus subtilis were isolated from blood cultures. The dog responded to aggressive antibiotic therapy, and the PDA was subsequently surgically corrected. After a series of treatments, the dog showed long-term improvement in clinical status.

Full Text Available OBJECTIVE: To describe the relative incidence, presentation, and evolvement of fetuses with early ductus constriction. METHODS: Twenty fetal echocardiograms indicating ductus constriction were reviewed in a population of 7000 pregnants. RESULTS: The cases were divided into group A (related to maternal use of cyclooxygenase inhibitors [n=7] and group B (idiopathics [n=13]. Mean gestational age was 32.5±3.1 (27-38 weeks and maternal age was 28.2±8.5 (17-42 years. Mean systolic velocity in the ductus was 2.22±0.34 (1.66-2.81 m/s, diastolic velocity 0.79±0.28 (0.45-1.5 m/s, and pulsatility index 1.33±0.36 (0.52-1.83. Two cases of ductal occlusion were noted. In 65% of the cases, an increase occurred in the right cavities; in 90% of the cases, tricuspid or pulmonary regurgitation, or both, occurred, with functional pulmonary atresia in 1 case. Diastolic velocity was greater in group A (1.13±0.33 than in group B (0.68±0.15 (P=0.008. The other data were similar in the 2 groups. The evolvement was not favorable in 4 patients from group B, including 1 death and 2 cases of persistent pulmonary hypertension. CONCLUSION: The high incidence of idiopathic constriction of the ductus arteriosus suggests that its diagnosis is underestimated and that many cases of persistence of fetal circulation in newborns may be related to constriction of the ductus arteriosus not diagnosed during intrauterine life. Group B had a lower severity but a risk of an unfavorable evolvement, suggesting a distinct alteration.

Persistent patency of the ductus arteriosus (PDA) is a common problem in preterm infants. The antacid cimetidine is a potent antagonist of the H2 histamine receptor but also inhibits certain cytochrome P450 enzymes (CYPs), which may affect DA patency. We examined whether cimetidine contributes to PDA and is mediated by CYP inhibition rather than H2 blockade. Analysis of a clinical trial to prevent lung injury in premature infants revealed a significant association between cimetidine treatment...
Full Text Available Abstract Background Diagnosis of extracardiac intrathoracic vascular anomalies is of clinical importance, but remains challenging. Traditional imaging modalities, such as radiography, echocardiography, and angiography, are inherently limited by the difficulties of a 2-dimensional approach to a 3-dimensional object. We postulated that accurate characterization of malformations of the aorta would benefit from 3-dimensional assessment. Therefore, multidetector-row computed tomography (MDCT was chosen as a 3-dimensional, new, and noninvasive imaging technique. The purpose of this study was to evaluate patients with 2 common diseases of the intrathoracic aorta, either patent ductus arteriosus or vascular ring anomaly, by contrast-enhanced 64-row computed tomography. Results Electrocardiography (ECG-gated and thoracic nongated MDCT images were reviewed in identified cases of either a patent ductus arteriosus or vascular ring anomaly. Ductal size and morphology were determined in 6 dogs that underwent ECG-gated MDCT. Vascular ring anomalies were characterized in 7 dogs and 3 cats by ECG-gated MDCT or by a nongated thoracic standard protocol. Cardiac ECG-gated MDCT clearly displayed the morphology, length, and caliber of the patent ductus arteriosus in 6 affected dogs. Persistent right aortic arch was identified in 10 animals, 8 of which showed a coexisting aberrant left subclavian artery. A mild dilation of the proximal portion of the aberrant subclavian artery near its origin of the aorta was present in 4 dogs, and a diverticulum analogous to the human Kommerell's diverticulum was present in 2 cats. Conclusions Contrast-enhanced MDCT imaging of thoracic anomalies gives valuable information about the exact aortic arch configuration. Furthermore, MDCT was able to characterize the vascular branching patterns in dogs and cats with a persistent right aortic arch and the morphology and size of the patent ductus arteriosus in affected dogs.

Full Text Available Abstract Acute traumatic patellar dislocation is a common injury in the active and young adult populations. MRI of the knee is recommended in all patients who present with acute patellar dislocation. Numerous operative and non-operative methods have been described to treat the injuries; however, the ideal management of the acute traumatic patellar dislocation in young adults is still in debate. This article is intended to review the studies to the subjects of epidemiology, initial examination and management.
Full Text Available Abstract Background Cases of giant hydronephroses are rare and usually contain no more than 1–2 litres of fluid in the collecting system. We report a remarkable case of giant hydronephrosis mimicking a progressive malignant abdominal tumour. Case presentation A 78-year-old cachectic woman presented with an enormous abdominal tumour, which, according to the patient, had slowly increased in diameter. Medical history was unremarkable except for a hysterectomy >30 years before. A CT scan revealed a giant cystic tumour filling almost the entire abdominal cavity. It was analysed by two independent radiologists who suspected a tumour originating from the right kidney and additionally a cystic ovarian neoplasm. Subsequently, a diagnostic and therapeutic laparotomy was performed: the tumour presented as a cystic, 35 × 30 × 25 cm expansive structure adhesive to adjacent organs without definite signs of invasive growth. The right renal hilar vessels could finally be identified at its basis. After extirpation another tumourous structure emerged in the pelvis originating from the genital organs and was also resected. The histopathological examination revealed a >15 kg hydronephrotic right kidney, lacking hardly any residual renal cortex parenchyma. The second specimen was identified as an ovary with regressive changes and a large partially calcified cyst. There was no evidence of malignant growth. Conclusion Although both clinical symptoms and the enormous size of the tumour indicated malignant growth, it turned out to be a giant hydronephrosis. Presumably, a chronic obstruction of the distal ureter had caused this extraordinary hydronephrosis. As demonstrated in our case, an accurate diagnosis of giant hydronephrosis remains challenging due to the atrophy of the renal parenchyma associated with chronic obstruction. Therefore, any abdominal cystic mass even in the absence of other evident pathologies should include the differential diagnosis of a
Full Text Available Introduction: Patent Ductus Arteriosus (PDA, a cardiac pathology commonly seen in preterm infants, has negative effects on mortality and morbidity. Persistent patency of PDA is positively correlated with respiratory distress syndrome (RDS, prolonged respiratory support, pulmonary hemorrhage, broncopulmonary dysplasia (BPD, necrotizing enterocolitis (NEC, intraventricular hemorrhage, renal failure, neurodevelopmental impairment (cerebral palsy, retinopathy of prematurity and death. The standard treatment regimen is to close symptomatic PDA and cyclooxygenase inhibitors such as indomethacin, ibuprofen are the first choises. Our aim in this study is to report PDA rate, treatment and complications in premature infants. Materials and Methods: This study retrospectively enrolled 103 infants born <33 gestational weeks, without any major congenital anomaly or congenital heart defects between January 2010-November 2011. Echocardiograms was performed in the first week. PDA related pulmonary hemorrhage, NEC, BPD, ROP and death were demonstrated.Results: Among of 103 infants, 45 were male and 58 were female. Seventy infants were born with cesarian section and 33 were born with normal labor. The mean gestational week was 29.7±2.2, the mean gestational week of infants with PDA was 28.8±2.3. The mean birth weight of infants was 1323±375 grams. The mean Apgar score was 7.25±1.83, the scores of infants with patent ductus arteriosus were significantly low (6.7±1.9. Echocardiography was performed on the mean of 4.8±4.4 days, PDA was determined in 48 of 103 infants (%46. The mean of birth weight of infants with persistant PDA was 1162±351 grams, it was 1465±340 g in the closed group. The rate of pulmonary hemorrhage, NEC, BPD, ROP and death was significantly higher in infants with PDA compared with infants having ductal closure (p<0.05.Conclusion: The early closure of PDA in very low birth weight infants will reduce both mortality and early or late

The purpose of this article is to provide a better understanding of pediatric traumatic brain injury and its management. Within the pediatric age group, ages 1 to 19, injuries are the number one cause of death with traumatic brain injury being involved in almost 50 percent of these cases. This, along with the fact that the medical system spends over $1 billion annually on pediatric traumatic brain injury, makes this issue both timely and relevant to health care providers. Over the course of this article the epidemiology, physiology, pathophysiology, and treatment of pediatric traumatic brain injury will be explored. Emphasis will be placed on the role of the early responder and the immediate interventions that should be considered and/or performed. The management discussed in this article follows the most recent recommendations from the 2012 edition of the Guidelines for the Acute Medical Management of Severe Traumatic Brain Injury in Infants, Children, and Adolescents. Despite the focus of this article, it is important not to lose sight of the fact that an ounce of prevention is worth a pound--or, to be more precise and use the average human's brain measurements, just above three pounds--of cure.

Full Text Available Abstract Background Whilst negative responses to traumatic injury have been well documented in the literature, there is a small but growing body of work that identifies posttraumatic growth as a salient feature of this experience. We contribute to this discourse by reporting on the experiences of 13 individuals who were traumatically injured, had undergone extensive rehabilitation and were discharged from formal care. All participants were injured through involvement in a motor vehicle accident, with the exception of one, who was injured through falling off the roof of a house. Methods In this qualitative study, we used an audio-taped in-depth interview with each participant as the means of data collection. Interviews were transcribed verbatim and analysed thematically to determine the participants' unique perspectives on the experience of recovery from traumatic injury. In reporting the findings, all participants' were given a pseudonym to assure their anonymity. Results Most participants indicated that their involvement in a traumatic occurrence was a springboard for growth that enabled them to develop new perspectives on life and living. Conclusion There are a number of contributions that health providers may make to the recovery of individuals who have been traumatically injured to assist them to develop new views of vulnerability and strength, make changes in relationships, and facilitate philosophical, physical and spiritual growth.

Percutaneous closure of the patent arterial duct in patients with interrupted inferior caval vein poses a technical challenge. A 12-year-old girl with a patent ductus arteriosus (PDA) and interrupted inferior caval vein is described in this report. The diagnosis of interrupted inferior caval vein and azygos continuation was made in the catheterization laboratory. A catheter was advanced and snared in the descending aorta. An exchange wire was advanced through the catheter and snared in the descending aorta. Then, an Amplatzer TorqVue 2 delivery sheath was advanced over the wire from the venous side and again snared in the descending aorta. An Amplatzer duct occluder (ADO) size 8/6 was advanced through the sheath while still holding the sheath with a snare. The device was opened. The sheath was then unsnared once the aortic disc was completely out. The sheath and the device were pulled back into the duct and the device was successfully implanted. The device was then released and it attained a stable position. An aortic angiogram was performed which showed complete occlusion
Full Text Available Background: Transcatheter occlusion of the patent ductus arteriosus (PDA is a minimally invasive treatment. The appropriate device size is chosen based on the angiographic measurement of the PDA. The current study aimed to assess the relationship between the transthoracic echocardiographic (TTE measurements of the PDA prior to the occlusion procedure and the actual size of the deployed device.Methods: We reviewed the available records of 7 patients (2 male who underwent the procedure at our institution (mean age: 21 ± 12.7 years, range: 7 to 46 years. PDA closure was performed successfully using the Amplatzer Duct Occluder (n = 5 and its Chinese copycat, Cardi-O-Fix Occluder (n = 2.Results: The TTE measurement of the aortic end diameter of the PDA showed a good linear regression correlation with the size of the implanted duct occluder [duct occluder size = 0.543 + (0.941× TTE measured diameter, R = 0.907; p value ≤ 0.01].Conclusion: TTE can provide a good estimation of the size of the Amplatzer duct occluder.

Full Text Available Background: Patent ductus arteriosus (PDA is a common form of congenital heart disease and forms about 5-10% of congenital heart diseases. Surgical closure is safe and effective; however, certain patients may experience some morbidity. Recently, transcatheter closure of PDA using the Amplatzer duct occluder has been shown to be safe and efficacious. Objectives: To evaluate whether transcatheter closure with this device offers an alternative to surgical closure of PDA. Patients and Methods: Between July 2006 to July 2008, 149 patients (98 females and 51 males with PDA underwent cardiac catheterization in an attempt to close their PDA by transcatheter approach using Amplatzer duct occluder device. Results: The patient′s age ranged from 4 months to 45 years (median 5 years. Successful PDA closure was achieved in 136 patients (91.2% with 100% complete closure rate within 24 hours after the procedure. Thirteen patients (8.7% had unsuccessful attempts, 11 (7.3% of them had failure of deployment of the device, while embolization of the device occurred in two of the patients (1.3%. Conclusions: Amplatzer duct occluder device is safe and effective for closure of different types and sizes of PDA with low rate of complication.

Patent ductus arteriosus (PDA) is a congenital cardiovascular malformation in which a fetal connection between the aorta and pulmonary artery remains patent after birth. This defect commonly results in clinical complications, even death, necessitating closure. Surgical ligation is the most common treatment but requires a thoracotomy and is therefore invasive. A minimally invasive option is preferable. A prototype device for PDA occlusion which utilizes shape memory polymer foams has been developed and evaluated using mechanical and in vitro experiments. Removal force and radial pressure measurements show that the prototype device exhibited a lower removal force and radial pressure than a commercially available device. The in vitro experiments conducted within simplified and physiological PDA models showed that the prototype does not migrate out of position into the pulmonary artery at either physiological or elevated pressures in multiple model configurations. While the radial pressure and removal force were lower than commercial devices, the device performed acceptably in the in vitro benchtop experiments warranting further prototype development.

Objective:We performed a multicenter study of preterm infants, who were about to undergo patent ductus arteriosus ligation, to determine whether echocardiographic indices of impaired myocardial performance were associated with subsequent development of catecholamine-resistant hypotension following ligation.Study Design:A standardized treatment approach for hypotension was followed at each center. Infants were considered to have catecholamine-resistant hypotension if their dopamine infusion was >15 μg kg(-1)min(-1). Echocardiograms and cortisol measurements were obtained between 6 and 14 h after the ligation (prior to the presence of catecholamine-resistant hypotension).Result:Forty-five infants were enrolled, 10 received catecholamines (6 were catecholamine-responsive and 4 developed catecholamine-resistant hypotension). Catecholamine-resistant hypotension was not associated with decreased preload, shortening fraction or ventricular output. Infants with catecholamine-resistant hypotension had significantly lower levels of systemic vascular resistance and postoperative cortisol concentration.Conclusion:We speculate that low cortisol levels and impaired vascular tone may have a more important role than impaired cardiac performance in post-ligation catecholamine-resistant hypotension.Journal of Perinatology advance online publication, 14 August 2014; doi:10.1038\\/jp.2014.151.

There is growing knowledge of the effects of stress on professionals, including various negative symptoms that may mirror the biopsychosocial effects exhibited by the victims of trauma. Multiple concepts including burn out, compassion fatigue, post-traumatic stress disorder (PTSD), and secondary traumatic stress, are terms that have been incorrectly interchanged with the term vicarious traumatization (VT). Clarity of vicarious victimization and understanding contributing factors is imperative in order to facilitate future research and implement timely and effective interventions, as well as sculpt evidence based practice. This concept anaylsis, complete with a concept map, discusses VT; related terminology; symptomology; prevention and relevant interventions; and discusses opportunities for personal/professional growth for nurses and especially forensic nurses working with victims of violence.

Full Text Available OBJECTIVE: To identify clinical and echocardiographic indicators of the necessity for early surgical closure of patent ductus arteriosus in preterm neonates. METHODS: The prospective study was conducted at the Neonatal Unit of Hospital Municipal Odilon Behrens between 2006 and 2010. The study population comprised 115 preterm neonates diagnosed with patent ductus arteriosus in the first week after birth, of whom 55 (group S were submitted to clinical and or surgical closure and 60 (group NS received non-surgical treatment. The parameters analyzed were birth weight, diameter of the ductus arteriosus (DAD, left atrial-to-aortic root diameter ratio (LA:Ao, the quotient of DAD² and birth weight (mm²/kg, and ductal shunting. RESULTS: The study population comprised 58 males and 57 females. The average birth weight of group S (924 ± 224.3 g was significantly (P=0.049 lower than that of group NS (1012.3 ± 242.8 g. The probability of the preterm neonates being submitted to surgical closure was 62.1% (P=0.006 when the DAD2/birth weight index was > 5 mm²/kg, 72.2% (P=0.001 when the LA:Ao ratio was > 1.5, and 61.2% when ductal shunting was high (P=0.025. CONCLUSION: The parameters DAD²/birth weight index > 5 mm²/kg, LA:Ao ratio > 1.5 and high ductal shunting were statistically significant indicators (P 1.5 was associated with the occurrence of shock, the probability of surgical closure increased to 78.4%.

Full Text Available Background and Objectives : Initial experience with transcatheter closure of patent ductus arteriosus (PDA using detachable coils and Amplatzer duct occluder devices is reported. We evaluated the outcome, complications, and influence of the learning curve, and also assessed the need of surgical backup for such interventional procedures. Methods: From January 2000 to December 2004, 121 patients underwent transcatheter closure of PDA. Aortic angiogram was performed to evaluate the size, position, and shape of the duct for appropriately choosing the occluder device type and size. A second aortic angiogram was performed 10 minutes after device deployment. Echocardiography was repeated at intervals of 24 hours, then at 1, 3, and 6 months after the procedure to assess complications. Stepwise multiple regression analysis was used to assess the role of experience in improving the outcome of the procedure. Results: Of 121 cases, four patients had pulmonary artery embolization of the occluder device which was successfully retrieved in the catheterization laboratory, while two others had embolization that required surgical intervention. Four patients had temporary residual leak, nine had protrusion of the device into the aorta without significant Doppler pressure gradient or hemolysis on follow-up, and five had partial hemodynamically insignificant obstruction to the left pulmonary artery. Statistical analysis showed that the effect of the learning curve and experience was responsible for 93% improvement in the procedural outcome over the five-year study period. Conclusion: Transcatheter occlusion of PDA is safe and effective alternative to surgery. Complications occurred in those with unfavorable duct anatomy and with the use of multiple coils. Surgical backup was important for such interventional procedures. Experience played a major role in the proper choice of device type and size which greatly influenced the outcome of the procedure.
Objective: To evaluate the effectiveness of transcatheter closure of re-canalized patent ductus arteriosus (PDA) after surgical ligation. Methods: Between June 1995 and November 2000, 14 patients (5 male, 9 female) with re-canalized PDA after surgical ligation underwent transcatheter closure, their median age was 13 years (range 4 to 48 years). The time between surgical ligation and the interventional procedure ranged from one month to twenty-two years. Implantations of Amplatzer duct occluder and Rashkind occluder were performed trans-venously. Cook coil occlusions was performed trans-arterially. Follow-up with X-ray radiograph and echocardiography was made 24 hours, 1, 3, 6 months, and more than 1 year after the procedure. Results: Twelve PDAs were of funnel shape, and the remaining two PDAs were of tubular shape. The median minimum diameter of re-canalized PDA after ligation was 4 mm (range 1 to 8 mm). Aortograms ten minutes after closure showed complete closure and trivial residual shunt in 11 and 3 patients, respectively. The technical success rate was 100%, and there were no complications. Echocardiography showed complete closure in all patients within 24 hours. All patients were discharged in one to two days after the procedure. At a follow-up of one to eighteen months in ten patients, there were no migration of devices and residual PDA. Conclusion: Transcatheter closure using Amplatzer duct occluder, coil (Cook company or Pfm company) and Rashkind occluder was an effective method for patients with re-canalized PDA after surgical ligation. It may be an alternative to second surgery owing to its safety, reliability, min-invasiveness, and short hospitalization

Case 1: A term male child was re-admitted on day 10 of life due to acute onset of respiratory distress. Physical examination revealed tachypnoea, tachycardia and blood pressure (BP) above the 95th centile in all four limbs. Cardiovascular examination revealed a short systolic murmur on the sternal border. Abdomen showed hepatomegaly of 3 cm below the costal margin. Chest X-ray showed a cardiothoracic ratio of 0.65 with normal vascularity. Ultrasound and Doppler of the kidneys and brain were normal. The high parasternal view showed a large ductus arteriosus aneurysm (DAA) of 2.0×2.5 cm. The baby was managed with inotropes and antihypertensives. CT angiogram showed 1.6×0.6 cm thrombosed DAA, which was extending from the posterior descending aorta to the ampulla. With the resolution of aneurysm BPs normalised and antihypertensives were stopped at 6 weeks of age. Case 2: A premature male neonate weighing 1.2 kg was admitted to the neonatal intensive care unit for respiratory distress syndrome. On the 4th day of life during routine measurement of vitals, the BP was consistently above 95th centile in all four limbs. Blood tests revealed thrombocytopenia that persisted inspite of single donor transfusions. The evaluation for sepsis was negative. The ultrasound and Dopplers of the kidneys and brain were all normal. A transthoracic echocardiogram showed a large DAA measuring 5×1.8 mm. Hypertension was managed with antihypertensives. Serial transthoracic echocardiogram showed organising DAA. CT angiogram showed 6 mm×2 mm thrombosed DAA. As the arterial BP normalised, antihypertensives were stopped on day 15 of life. The baby was discharged on day 29 of life and on follow-up BP remained normal. PMID:24798362
Objective: To explore the value and technique key point of retrograde wire-track based new application in percutaneous transcatheter closure of persistent duct arteriosus (PDA). Methods: From May 1998 to July 2005, 831 patients with PDA underwent transcatheter closure, 11 cases ( about 1.3% ) with anatomy too difficult to be antegradely approached and were closed by building femoral artery-PDA- pulmonary artery-femoral vein wire-track. The mean age of the 11 patients was (42±20) years (ranged from 8 to 76 years), the mean weight was (61±23) kg (ranged from 20 to 100 kg); the mean diameter of PDA was (4.1±1.9) mm (ranged from 1.6 to 6.7). Results: Wire-track were smoothly built up in all the 10 patients and then finished deployment according to Amplatzer method. The size of occluders were 6/4 mm (3 cases), 8/6 mm(4 cases), 10/8 mm(2 cases), 12/10 mm( 1 case), 14/12 mm(1 case). There was complete closure in 10 patients immediately, and tiny residual shunt in only 1 patient at the descending aortography. Twenty minutes later, the tiny residual shunt disappeared. There were no other complications. Conclusion: Deformed ostium and difficult anatomy of PDA leads to failure to track the delivery system to cross the ductus from the pulmonary artery. This new application by building femoral artery-PDA-pulmonary artery-femoral vein wire-track can overcome the technical difficulty safely and effectively. (authors)
Full Text Available Abstract Introduction Single ventricle and truncus arteriosus are both rare congenital cardiac syndromes with limited survival. Their occurrence together is extremely uncommon and prolonged survival is exceptionally rare. We present the case of a patient who had both of these defects with survival to age 45. Case presentation We describe the vase of a 45-year-old man with the unusual occurrence of two very rare congenital cardiac defects. He was found to have both truncus arteriosus and single ventricle with long survival. His history, clinical course, and anatomic findings are discussed along with the factors which may have contributed to his longevity, which is unique in the medical literature. His management reflected the state of medical knowledge at the time when he presented, and although alternate approaches may have been utilized if the patient presented today, this case does indicate the efficacy of the management options available at the time and place of the patient's contacts with the medical care system in Belarus. We discuss the findings, frequency, classification, and management of both of these congenital defects. Conclusion This case demonstrates that patients with very complex congenital cardiac disease may survive to adulthood, presenting challenges in both medical and surgical treatment. As the management of these patients is constantly evolving, and interventional techniques are improving, patients such as this with prolonged survival will be more common, with each case providing insights to future treatment. Challenges in management may include prior care provided in health care systems with limited resources.

Purpose This study aimed to evaluate the correlation, according to postnatal age, between plasma B-type natriuretic peptide (BNP) levels and echocardiographic parameters for the assessment of patent ductus arteriosus (PDA) in preterm infants with respiratory distress. Methods We enrolled 42 preterm infants with respiratory distress who underwent serial echocardiographic evaluation with simultaneous plasma BNP measurements until ductal closure. The correlations between BNP levels and the following 4 representative echocardiographic parameters were studied: diameter of the ductus arteriosus (DA), ratio of the left atrial diameter to the aortic diameter (LA/Ao), ratio of the PDA diameter to the infant's left pulmonary artery diameter (PDA/LPA), and the antegrade diastolic flow of LPA (DFLPA). Results BNP levels were significantly correlated to the magnitude of the ductal shunt, comprising the DA diameter, PDA/LPA ratio, LA/Ao ratio, and antegrade DFLPA for the overall study period. The earliest significant correlation, starting from postnatal day 2, was observed between the LA/Ao ratio and BNP levels. The PDA/LPA ratio and the antegrade DFLPA showed significant correlations with BNP levels postnatal day 3 onward, and with the DA diameter, postnatal day 5 onward. Conclusion BNP levels and echocardiographic parameters showed a positive correlation, but the significance of the correlations differed according to the postnatal age, especially during the first few days of life.

A 47-year-old patient presented with a chylous knee effusion and traumatic infected skin lacerations. The diagnosis of septic arthritis was considered because of purulent looking joint fluid, spuriously high synovial fluid white cell count, and signs of acute knee synovitis. Synovial fluid lipid analysis showed increased total lipids due to high concentration of neutral lipids, mainly triglycerides, and repeated knee radiographs showed a small fracture of the tibial spine.

There is little consensus regarding the use of echocardiography in patent ductus arteriosus (PDA) treatment in preterm infants. The use of troponin T (cTnT) and N-terminal Pro-BNP (NTpBNP) in combination with echocardiography assessment may facilitate the development of a superior predictive model.

Abstract Background: Traumatic diaphragmatic hernias (TDHs) are sometimes difficult to identify at an early stage and can consequently result in diagnostic delays with life-threatening outcomes. It is the aim of this case study to highlight the difficulties encountered with the earlier detection of traumatic diaphragmatic hernias. Methods: Clinical data of patients who received treatment for delayed traumatic diaphragmatic hernias in registers of the First Affiliated Hospital of Xi’an Jiaotong University from 1998 to 2014 were analyzed retrospectively. Results: Six patients were included in this study. Left hemidiaphragm was affected in all of them. Most of the patients had a history of traffic accident and 1 a stab-penetrating injury. The interval from injury to developing symptoms ranged from 2 to 11 years (median 5 years). The hernial contents included the stomach, omentum, small intestine, and colon. Diaphragmatic injury was missed in all of them during the initial managements. All patients received operations once the diagnosis of delayed TDH was confirmed, and no postoperative mortality was detected. Conclusions: Delayed TDHs are not common, but can lead to serious consequences once occurred. Early detection of diaphragmatic injuries is crucial. Surgeons should maintain a high suspicion for injuries of the diaphragm in cases with abdominal or lower chest traumas, especially in the initial surgical explorations. We emphasize the need for radiographical follow-up to detect diaphragmatic injuries at an earlier stage. PMID:27512848

Patent ductus arteriosus (PDA) accounts for 6 - 11% of all congenital heart defects. Complications of PDA include congestive heart failure, repeated chest infections, pulmonary hypertension, and an increased risk of infective endocarditis. Transcatheter closure of PDA has largely replaced surgical ligation in different age groups. Currently, surgical intervention is restricted to premature babies or small infants with large symptomatic PDA, cases with unfavorable duct anatomy, and whenever the cost of the closure devices is unaffordable. PDA was the first example of congenital heart dis-ease to be treated by transcatheter closure, which becomes an established form of treatment for the majority of patients with PDA and as a safe alternative to surgery. The per-cutaneous technique was first described by Porstmanur et al., since then various devices such as Rashkind PDA umbrella, button device, PDA coils and most recently the Amplatzer duct occluder (ADO) have been introduced. The ADO device was designed to provide the most desirable characteristics for a percutaneous closure device that can be used in most if not all patients with PDA. These include user - friendly delivery system, high complete closure rate, small delivery system (allowing its use in small infants), trans-venous delivery route, ability to adapt to various PDA sizes and types, and the ability to retrieve or reposition the device prior to release from a secure delivery system. Common complications of trans-catheter closure of PDA include residual shunt, left pulmonary artery (LPA) obstruction, protrusion of the device into the aorta, and embolization of the device. Incidence of complications increases with certain types and large size ducts, and with the use of multiple coils for occlusion. There are only a few reports correlating out-come and complications with the learning curve and experience. In this study, we are reporting our initial experience with PDA closure using Amplatzer duct occluder (ADO

Full Text Available Endothelial cells (ECs lining the blood vessels serve a variety of functions and play a central role in the homeostasis of the circulatory system. Since the ductus arteriosus (DA has different arterial characteristics from its connecting vessels, we hypothesized that ECs of the DA exhibited a unique gene profile involved in the regulation of DA-specific morphology and function. Using a fluorescence-activated cell sorter, we isolated ECs from pooled tissues from the DA or the descending aorta of Wistar rat fetuses at full-term of gestation (F group or neonates 30 minutes after birth (N group. Using anti-CD31 and anti-CD45 antibodies as cell surface markers for ECs and hematopoietic derived cells, respectively, cDNAs from the CD31-positive and CD45-negative cells were hybridized to the Affymetrix GeneChip® Rat Gene 1.0 ST Array. Among 26,469 gene-level probe sets, 82 genes in the F group and 81 genes in the N group were expressed at higher levels in DA ECs than in aortic ECs (p2.0. In addition to well-known endothelium-enriched genes such as Tgfb2 and Vegfa, novel DA endothelium-dominant genes including Slc38a1, Capn6, and Lrat were discovered. Enrichment analysis using GeneGo MetaCore software showed that DA endothelium-related biological processes were involved in morphogenesis and development. We identified many overlapping genes in each process including neural crest-related genes (Hoxa1, Hoxa4, and Hand2, etc and the second heart field-related genes (Tbx1, Isl1, and Fgf10, etc. Moreover, we found that regulation of epithelial-to-mesenchymal transition, cell adhesion, and retinol metabolism are the active pathways involved in the network via potential interactions with many of the identified genes to form DA-specific endothelia. In conclusion, the present study uncovered several significant differences of the transcriptional profile between the DA and aortic ECs. Newly identified DA endothelium-dominant genes may play an important role in DA

Multiple regression analysis showed Era 2 birth was a predictor of CLD. However, Poisson regression analysis determined the predictors of all seven major Vermont Oxford Network morbidities were earlier gestational age, lower birth weight, and male gender, not the era of birth. Significantly more infants were discharged home with PDAs in Era 2.Conclusion: Permissive tolerance of PDAs may increase the risk of CLD and Death after Day 7 or CLD but is not associated with significant changes in other Vermont Oxford Network morbidities.Keywords: premature infant

Almost a century ago, the first clinical account of the punch-drunk syndrome emerged, describing chronic neurological and neuropsychiatric sequelae occurring in former boxers. Thereafter, throughout the twentieth century, further reports added to our understanding of the neuropathological consequences of a career in boxing, leading to descriptions of a distinct neurodegenerative pathology, termed dementia pugilistica. During the past decade, growing recognition of this pathology in autopsy studies of nonboxers who were exposed to repetitive, mild traumatic brain injury, or to a single, moderate or severe traumatic brain injury, has led to an awareness that it is exposure to traumatic brain injury that carries with it a risk of this neurodegenerative disease, not the sport or the circumstance in which the injury is sustained. Furthermore, the neuropathology of the neurodegeneration that occurs after traumatic brain injury, now termed chronic traumatic encephalopathy, is acknowledged as being a complex, mixed, but distinctive pathology, the detail of which is reviewed in this article.

Pulmonary arterial dissection is an uncommon but usually a deadly complication of chronic pulmonary hypertension. A 26-year-old female patient was admitted to our clinics with sudden dyspnea and chest discomfort one hour after giving birth to twins by vaginal delivery. An echocardiography was performed with a pre-diagnosis of pulmonary embolism. However, echocardiographic examination revealed a dilated main pulmonary artery and a dissection flap extending from main pulmonary artery to left pulmonary artery. In summary, in this report, we described a very rare case of pulmonary artery dissection in a pregnant patient with a previously un-diagnosed patent ductus arteriosus without an obvious rise in pulmonary artery pressure and reviewed the relevant literature.
Full Text Available Background: Although, patent ductus arteriosus (PDA is associated with significant morbidity due to hemodynamic instability in preterm infants, the effect of ductus closure on mortality and morbidity is a controversial issue. The aim is to evaluate the efficacy of oral and intravenous (IV ibuprofen treatment on ductal closure and effects on mortality and bronchoplumonary dysplasia. Materials and Methods: The medical records of 292 premature infants treated at Ege University Neonatal Intensive Care Unit were retrospectively evaluated. Patients were classified into 3 groups as; No PDA, hemodynamically insignificant PDA (hiPDA and hemodynamically significant PDA (hsPDA according to the presence and hemodynamical significance of PDA by echocardiography. hsPDA group was treated with IV or oral ibuprofen. Results: Patent ductus arteriosus was diagnosed by routine echocardiography in 145 patients, of whom 78 (53.7% had hsPDA. All 65 infants with hiPDA had spontaneous PDA closure. Echocardiographic measurements were similar to those patients treated with oral or IV ibuprofen, as in the response rate to treatment without serious adverse effects. The presence of respiratory distress syndrome, surfactant therapy, late sepsis, bronchopulmonary dysplasia (BPD and mortality rates were significantly higher in patients with hsPDA. However, with stepwise logistic regression; 5th min Apgar score (odds ratio [OR], 1.321, 95% confidence interval [CI], 1.063-1.641, P = 0.012 and gestational age (OR, 1.422, 95% CI, 1.212-1.662, P < 0.001 were the only significant variables associated with mortality. Gestational age (OR, 0.680, 95% CI, 0.531-0.871, P = 0.002 was the only significant variable associated with BPD shown with logistic regression. Conclusion: Ibuprofen treatment is effective for hsPDA closure with minimal side effects. HiPDA can close spontaneously; therefore treatment decision should be individualized. However, medical treatment of PDA does not reduce

Full Text Available Introduction. Although fractures of humeral shaft show excellent results with conservative management, nonunion does occur. Case Report. We bring forth the case of a young male with a 1.5-year-old hypertrophic nonunion of the humerus mimicking an enchondroma. The initial X-ray images of the patient appeared to be an enchondroma, which only on further evaluation and histopathological analysis was diagnosed conclusively to be a hypertrophic nonunion. Discussion. Enchondromas are often incidentally diagnosed benign tumours. It is however not common to misdiagnose a hypertrophic nonunion to be an enchondroma. We present this case to highlight the unique diagnostic dilemma the treating team had to face.
Full Text Available Benzalkonium chloride (BAC is a frequently used disinfectant and its most well-known side effect is contact dermatitis. In this report, two children who had vesicular dermatitis, headache, lethargy, fever and encephalopathy mimicking Herpes zoster encephalitis were presented. Their consciousness level improved on the second day. From the medical history it was understood that the mother had applied 20% BAC solution to the scalps of two children. The aim of the presentation of this report is to draw attention to the fact that BAC application to the scalp for treating pediculosis capitis may resemble the herpes encephalitis clinical picture.

Actinomycosis is a rare, chronic, spreading, suppurative,granulomatous and fibrosing infection. Actinomyces are normal inhabitants of the oral cavity and gastrointestinal tract. They rarely cause disease and are seldom reported as pathogens. Herein, we reported on a 69-year-old male patient who had undergone Whipple's operation due to ampulla Vater carcinoma, and became infected with actinomycosis at the pancreaticojejunostomy, which mimicked a recurrent malignancy. He was treated with radical resection of the mass at the pancreaticojejunostomy and had an uneventful postoperative course.
Two children with right middle lobe lesions mimicking pericardial effusion on ultrasonography are presented. They were admitted with fever and chest radiographs showed atelectasis or consolidation of the middle lobe of the right lung along the right heart border. A low-echogenic layer suggesting pericardial fluid was seen on ultrasonography, but with a spatial distribution closely corresponding to the lesions seen on the chest radiographs. If the possibility that a lung lesion adjacent to the heart can simulate pericardial fluid on ultrasonography is kept in mind, the correct diagnosis should not be difficult to make. (orig.)

Where the attacker creates mimicked web pages from the legitimate web pages to fool users. In this paper, we propose an effective anti-phishing solution, by combining image based visual similarity based approach to detect plagiarized web pages. We used effective algorithms for our detection mechanism, speeded up Robust Features (SURF algorithm in order to generate signature based on extracting stable key points from the screen shot of the web page. When a legitimate web page is registered with our system, this algorithm applied on that web page in order to generate signatures, and these signatures are stored in the database for our trained system. When there is a suspected web page, this algorithm is applied to generate both the signatures of the suspected page and is verified against our database of corresponding legitimate web pages. Our results verified that our proposed system is very effective to detect the mimicked web pages with minimal false positives

Inflammatory myofibroblastic tumors (IMTs) are rare. IMTs of the head and neck occur in all age groups, from neonates to old age, with the highest incidence occurring in childhood and early adulthood. An IMT has been defined as a histologically distinctive lesion of uncertain behavior. This article describes an unusual case of IMT mimicking apical periodontitis in the mandible of a 42-year-old man. At first presentation, the patient showed spontaneous pain and percussion pain at teeth #28 to 30, which continued after initial endodontic treatment. Panoramic radiography revealed a radiolucent lesion at the site. Cone-beam computed tomographic imaging showed osteolytic lesions, suggesting an aggressive neoplasm requiring incisional biopsy. Histopathological examination indicated an IMT. The lesion was removed en bloc under general anesthesia, and the patient manifested no clinical evidence of recurrence for 24 months. Lesions of nonendodontic origin should be included in the differential diagnosis of apical periodontitis. Every available diagnostic tool should be used to confirm the diagnosis. Cone-beam computed tomographic imaging is very helpful for differential diagnosis in IMTs mimicking apical periodontitis. PMID:26602450
Only 24 patients with post-traumatic osteomyelitis were found from records covering a period of five years. Twenty-two of them with complete medical histories are reviewed here. The radiographs were usually taken through plaster of Paris, and therefore the radiological diagnosis was established later than the clinical one in half of the cases. There were only four cases with a true delay. The primary radiological signs leading to the osteomyelitis diagnosis appeared on average 4.3 months after the assumed time of infection. It is our feeling that the current widespread use of antibiotics causes the diagnosis to be delayed even more than it was in the days of haematogenous osteomyelitis. Continuous formation of periosteal new bone layers indicated poorer prospects for healing of the osteomyelitis. (orig.)

We hereby report a 35-year-old gentleman who sustained wedge compression fracture of L-1 vertebral body 15 years back and had complete paraplegia with bowel/bladder involvement. The neurological deficit recovered with minimal residual motor deficits and erectile dysfunction. He presented now with increasing neurological deficits associated with pain and paresthesia. The MRI spine showed a syrinx extending from the site of injury up to the medulla. He underwent a syringo-peritoneal shunt and at follow-up his pain and motor functions had improved but erectile dysfunction was persisting.

Full Text Available Traumatic injury of the diaphragm ranges from 0.6 to 1.2% and rise up to 5%among patients who were victims of blunt trauma and underwent laparotomy.Clinical suspicion associated with radiological assessment contributes to earlydiagnosis. Isolated diaphragmatic injury has a good prognosis. Generallyworse outcomes are associated with other trauma injuries. Bilateral andright diaphragmatic lesions have worse prognosis. Multi detector computed tomography (MDCT scan of the chest and abdomen provides better diagnosticaccuracy using the possibility of image multiplanar reconstruction. Surgicalrepair via laparotomy and/ or thoracotomy in the acute phase of the injury hasa better outcome and avoids chronic complications of diaphragmatic hernia.The authors present the case of a young male patient, victim of blunt abdominaltrauma due to motor vehicle accident with rupture of the diaphragm, spleenand kidney injuries. The diagnosis was made by computed tomography of thethorax and abdomen and was confirmed during laparotomy.

The literature surrounding minor traumatic brain injury is complex, methodologically challenging, and controversial. Although we lack a consistent standardized definition, the annual rate is likely in excess of 200 per 100,000 children. The proportion of children with minor traumatic brain injury who will require neurosurgery is certainly return to play is currently recommended. The recurrence risk for subsequent concussions is elevated, but there is limited documentation of the effectiveness of preventative efforts. Much remains to be learned. PMID:17178354

Post-traumatic stress disorder (PTSD) is characterised by disabling symptoms of re-experiencing a traumatic event, avoidance behaviour, and hyperarousal (e.g., irritability or hypervigilance), lasting at least 1 month. PTSD may affect 10% of women and 5% of men at some stage, and symptoms may persist for several years.Risk factors include major trauma, lack of social support, peritraumatic dissociation, and previous psychiatric or personality factors.

Only about 1% of marine bacteria have been brought into culture using traditional techniques. The purpose of this study was to investigate if mimicking the natural bacterial environment can increase culturability.We used marine substrates containing defined algal polymers or gellan gum as...... solidifying agents, and enumerated bacteria from seawater and algal exudates. We tested if culturability could be influenced by addition of quorum sensing signals (AHLs). All plates were incubated at 15°C. Bacterial counts (CFU/g) from algal exudates from brown algae were highest on media containing algal...... polymers. In general, bacteria isolated from algal exudates preferred more rich media than bacteria isolated from seawater. Overall, culturability ranged from 0.01 to 0.8% as compared to total cell count. Substitution of agar with gellan gum increased the culturability of seawater bacteria approximately...
Pelvic-peritoneal tuberculosis is a common extrapulmonary site in young females mimicking an advanced ovarian malignancy. We present 2 cases with the classical triad of advanced-stage ovarian carcinoma-ascites, abdominopelvic masses and elevated serum CA-125 levels. Laparoscopic examination revealed peritoneal nodules which on biopsy showed granulomatous inflammation and no malignant cells. Patients were started on anti-tuberculous therapy and on follow-up their symptoms as well as CA-125 levels normalized. Medical awareness of peritoneal tuberculosis is lacking and many young women with this disease undergo unnecessary extended surgery. Diagnostic laparoscopy combined with peritoneal biopsy seems to be a sufficient and safe method to provide a definitive diagnosis for this curable infection. If left untreated, the disease may disseminate and result in significant organ dysfunctions particularly infertility. (author)

High-altitude cerebral oedema (HACO) is the most fatal high-altitude illness seen by rural physicians practising in high-altitude areas. HACO presents clinically with cerebellar ataxia, features of raised intracranial pressure (ICP) and coma. Early identification is important as delay in diagnosis can be fatal. We present two cases of HACO presenting with focal deficits mimicking stroke. The first patient presented with left-sided hemiplegia associated with the rapid deterioration in the sensorium. Neuroimaging revealed features suggestive of vasogenic oedema. The second patient presented with monoplegia of the lower limb. Neuroimaging revealed perfusion deficit in anterior cerebral artery territory. Both patients were managed with dexamethasone and they improved dramatically. Clinical picture and neuroimaging closely resembled acute ischaemic stroke in both cases. Thrombolysis in these patients would have been disastrous. Recent travel to high altitude, young age, absence of atherosclerotic risk factors and features of raised ICP concomitantly directed the diagnosis to HACO. PMID:24671373

Differential diagnosis between spinal metastasis and infectious spondylodiscitis is one of the occasional challenges in daily clinical practice. We encountered an unusual case of spinal metastasis in a 75-year-old female breast cancer patient that mimicked infectious spondylodiscitis. Magnetic resonance imaging (MRI) showed diffuse bone marrow infiltrations with paraspinal soft tissue infiltrative changes in 5 contiguous cervical vertebrae without significant compression fracture or cortical destruction. These MRI findings made it difficult to differentiate between spinal metastasis and infectious spondylodiscitis. Infectious spondylodiscitis such as tuberculous spondylodiscitis was regarded as the more appropriate diagnosis due to the continuous involvement of > 5 cervical vertebrae. The patient's clinical presentation also supported the presumptive diagnosis of infectious spondylodiscitis rather than spinal metastasis. Intravenous antibiotics were administered, but clinical symptoms worsened despite treatment. After pathologic confirmation by computed tomography-guided biopsy, we were able to confirm a final diagnosis of spinal metastasis.
Full Text Available Eventration of diaphragm is a condition in which there is abnormal elevation of the diaphragm as a result of thinning of muscular layer. It can be congenital as well as acquired. It is more common left sided. Herniation of the abdominal contents can be there. Clinical manifestations range from asymptomatic to life threatening respiratory distress requiring mechanical ventilator support. Ultrasound provides valuable information regarding the integrity of the diaphragm. Other imaging modalities include fluoroscopy, CT and MRI that provide valuable information when diagnosis is in doubt. We are presenting a case report of 25-year-old male with eventration of left hemidiaphragm mimicking as cavity. After taking detail history, examination and proper investigations we finally reached to this diagnosis.

Inaugural traumatic patellar dislocation is most often due to trauma sustained during physical or sports activity. Two-thirds of acute patellar dislocations occur in young active patients (less than 20 years old). Non-contact knee sprain in flexion and valgus is the leading mechanism in patellar dislocation, accounting for as many as 93% of all cases. The strong displacement of the patella tears the medial stabilizing structures, and notably the medial patellofemoral ligament (MPFL), which is almost always injured in acute patellar dislocation, most frequently at its femoral attachment. Lateral patellar glide can be assessed with the knee in extension or 20° flexion. Displacement by more than 50% of the patellar width is considered abnormal and may induce apprehension. Plain X-ray and CT are mandatory to diagnose bony risk factors for patellar dislocation, such as trochlear dysplasia or increased tibial tubercle-trochlear groove distance (TT-TG), and plan correction. MRI gives information on cartilage and capsulo-ligamentous status for treatment planning: free bodies or osteochondral fracture have to be treated surgically. If patellar dislocation occurs in an anatomically normal knee and osteochondral fracture is ruled out on MRI, non-operative treatment is usually recommended. PMID:25592052

Post-traumatic headache (migraine) is the most common symptom of concussion and traumatic brain injury. An expert opinion-based review along with a literature review (PubMed) was conducted looking at known interventional procedures for post-traumatic headache using the keywords post-traumatic headache, post-traumatic migraine headache, concussion, mild traumatic brain injury, and traumatic brain injury and the following categories: mechanism, pathophysiology, treatment, physical therapy, neurostimulation, Botox@/Onabotulinum toxin, and surgical intervention. The results returned a total of 181 articles of which 52 were selected. None of the articles included randomized placebo-controlled studies, and most were either prospective or retrospective case analysis and/or review articles or consensus opinion papers, with most studies yielding positive results. Despite a lack of hard evidence, interventional procedures, alone or in combination, appear to be an effective treatment for post-traumatic headaches. PMID:27130542

Objective: To explore the feasibility and effectiveness of transcatheter closure of patent ductus arteriosus (PDA) with Amplatzer occluder by using single venous approach method under ultrasound monitoring. Methods: During the period from May 2003 to April 2010, transcatheter closure of PDA were performed in 123 cases. Of the 123 patients, the procedure was accomplished by using arteriovenous dual approach method in 46 and by using single venous approach method in 77. All the procedures were monitored by ultrasound. The shape, size of PDA and immediate therapeutic results were checked with angiography in arteriovenous dual approach method or with ultrasonography in single venous approach method. The size of Amplatzer occluder was individually selected according to the smallest diameter of PDA. Echocardiography was performed at 3 days, one, 6 and 12 months after the procedure to evaluate the results. Results: Successful device placement with the initially selected occluder was obtained in 118 cases. In 4 cases the procedure was eventually completed after a bigger occluder was employed to replace the initial one, while in one case a smaller occluder had to use to replace the first one. The technical success rate was 100%. Conclusion: The transcatheter closure of PDA with Amplatzer occluder under ultrasound monitoring by single venous approach method is clinically effective and feasible. Being technically simple and time-saving, this single venous approach method is of great value in clinical practice. (authors)
We report a case wherein a dysmorphic four-month-old infant (weighing 4.5 kgs) with an 8 mm atrial septal defect (ASD), a 1.5 mm patent ductus arteriosus (PDA), a 2 mm mid-muscular ventricular septal defect (VSD) associated with chronic lung disease, and severe pulmonary hypertension, was successfully managed using a hybrid approach, without the use of cardiopulmonary bypass (CPB). Through a median sternotomy, the PDA was ligated and the ASD was closed with a 9 mm Amplatzer septal occluder implanted through peratrial access. The VSD was left untouched. Serial echocardiograms showed complete closure of the ASD and PDA, with progressive normalization of the pulmonary artery (PA) pressures within three months. The child rapidly gained weight and was weaned from sildenafil and oxygen administration. After 12 months, the VSD closed spontaneously and the child remained well, with normal PA pressures. A hybrid approach without the use of CPB should be considered in the management of infants with congenital heart disease, associated with chronic lung disease and pulmonary hypertension

Persistent patency of the ductus arteriosus (PDA) is a common problem in preterm infants. The antacid cimetidine is a potent antagonist of the H2 histamine receptor but it also inhibits certain cytochrome P450 enzymes (CYPs), which may affect DA patency. We examined whether cimetidine contributes to PDA and is mediated by CYP inhibition rather than H2 blockade. Analysis of a clinical trial to prevent lung injury in premature infants revealed a significant association between cimetidine treatment and PDA. Cimetidine and ranitidine, both CYP inhibitors as well as H2 blockers, caused relaxation of the term and preterm mouse DA. CYP enzymes that are inhibited by cimetidine were expressed in DA subendothelial smooth muscle. The selective CYP3A inhibitor ketoconazole induced greater DA relaxation than cimetidine, whereas famotidine and other H2 antagonists with less CYP inhibitory effects caused less dilation. Histamine receptors were developmentally regulated and localized in DA smooth muscle. However, cimetidine caused DA relaxation in histamine-deficient mice, consistent with CYP inhibition, not H2 antagonism, as the mechanism for PDA. Oxygen-induced DA constriction was inhibited by both cimetidine and famotidine. These studies show that antacids and other compounds with CYP inhibitory properties pose a significant and previously unrecognized risk for PDA in critically ill newborn infants. PMID:23454087

@@ A 36-years-old female had heart palpitation and chest press for five years and the symptoms had been worsening for half a year. She was diagnosed with patent ductus arteriosus with moderate pulmonary hypertension in a local hospital 5 years before but was not operated. Physical examination showed: T 37℃, P 87?bpm, R 18?bpm and BP 130/70?mm?Hg. There was no distension of the jugular vein, and the lungs were clear. There was continuous mechanic murmur at the second intercostal space, and grade 2 systolic blowing murmur at the apex. P2 was strengthened. The liver and spleen were not enlarged and there was no edema in either leg. ECG showed a pulmonary P wave and right ventricular hypertrophy. Chest X-ray film showed pulmonary segment projection 3?cm, and the dimension of the right inferior pulmonary artery bed increased to 3?cm in diameter. On echocardiography, both atria, the pulmonary artery and the right ventricle were enlarged.

Between May 1997 and June 2000, 69 patients, ages 0.1 to 34 years, underwent attempted anterograde transcatheter closure of a patent ductus arteriosus (PDA) using the Amplatzer Duct Occluder (ADO). The ADO is a cone-shaped, self-centering, and repositionable occluder made of nitinol wire mesh. A 5Fr to 7Fr sheath was used for the delivery of the device. The mean PDA diameter (at the pulmonary end) was 4.6 +/- 1.9 mm (range 1 mm-8.5 mm). Sixty-seven of the 69 patients had successful device placement. The mean ADO smallest diameter was 6.9 +/- 1.8 mm (range 4 mm-12 mm). Complete angiographic closure occurred in 62 (92.5%) of 67 patients (95% confidence interval, 88.22%-98.77%). In five patients, there was a trivial residual shunt immediately after the procedure. At 24 hours, color Doppler flow imaging revealed complete closure in all 67 (100%) patients. The unsuccessful attempts occurred in two patients with a small, 1-mm diameter native PDA and residual PDA after surgical occlusion. Fluoroscopy time was 7.6 +/- 1.8 minutes (4 min-18 min). No complications were observed. At a median follow-up of 1.5 years (range 0.25 to 3.2 years), all patients had complete closure without complications. We conclude that transcatheter closure using the ADO is a highly effective and safe treatment for most patients with PDA. PMID:12053313
Full Text Available Since indomethacin has many side effects, ibuprofen has been started to be used with beneficial results and less side effects for the closure of patent ductus arteriosus (PDA in recent years. The frequency of PDA, and the effects and side effects of oral ibuprofen were investigated by echocardiographic evaluation, in 164 preterm neonates in Neonatology Unit of Dicle University,between April and December 2004. Oral ibufrofen was given at 10 mg/kg/day dose to infants who had significant left-right shunt on the third day of birth but those who had contraindication for ibuprofen were excluded. By daily echocardiographic evaluations in those without closure after the first dose, a second and third dose of 5 mg/kg/day were given if necessary. Ductus closure has ocured in 24 of 27 (88.8% patients, at a mean period of 1.7±0.9 (1-4 days. Complications like hyponatremia, hypercreatininemia, thrombocytopenia, and necrotizing enterocolitis were not seen. Only in one patient intracranial hemorrhage was occured two days after the treatment. In conclusion, treatment with oral ibuprofen is an effective and safe treatment method for the closure of the PDA in preterm infants.
Full Text Available Introduction: We decided to investigate the effects of injecting Indomethacin on reducing complications of Patent Ductus Arteriosus (PDA and the need for prolonged mechanical ventilation. Methods: During this randomized clinical trial, 70 premature infants with matched gestational age and birth weight were divided into case and control groups. In the study group, intravenous indomethacin started from the first 2-12 hours of birth. All patients were followed by echocardiography at the fourth day and skull ultrasound in the second week. Results: Symptomatic PDA rate was significantly higher in the control group (25.7% vs. 0%; P≤0.001. Incidence of grade 1-3 intraventricular hemorrhage was higher in the control group and the ratio of needed time for respiratory support in the control group to the case group was approximately 2.1. Conclusion: Intravenous Indomethacin reduced the number of PDA cases and incidence of grade 2 and 3 intraventricular hemorrhage, without any short term side effects.

Post-traumatic stress disorder is a very broad category among mental disorders. Since its inclusion in DSM-III, the diagnostic criteria of post-traumatic stress disorder has undergone a number of changes. The diagnosis and treatment of people who have some symptoms of post-traumatic stress disorder without meeting full criteria still remains controversial. Although subthreshold post-traumatic stress disorder has been debated since it was first defined, the presence of subthreshold post-trauma...

The restoration of a traumatized tooth may require minimally invasive or more extensive treatment options. The majority of injuries occur in the younger population, so management should consider the long-term outcome, failure and future treatment needs over the course of, often, many decades. The aim should be to provide a tooth-restoration complex that closely mimics the functional and aesthetic qualities of an intact tooth for as long as possible. This narrative review will assess the relevant literature pertinent to restoration of traumatized teeth in order to provide guidance for the practising clinician. PMID:26923452
Chemical compositions and microsturcture of mature human tooth enamel were investigated by XRD , FTIR and SEM to further understand the characteristics of tooth enamel. In order to obtain apatite crystals chemically and structurally similar to those in tooth enamel, biomimetic way was employed. Selfassembled monolyers terminated with-SO3 H groups were used as deposition substrates and 1.5 SBF ( the concentrations of Ca2+ and PO43- ions 1.5 times than those in simulated body fluid ) with and without 5 ppm F- were used as soaking medium. The XRD and FTIR results showed that both the deposited fluoride-substituted hydroxyapatite( F-HAp ) crystals in 1.5 SBF with F- and hydroxyapatite ( HAp ) crystals in 1.5 SBF were carbonate-containing, mimicking human tooth enamel in chemical compositions. The SEM photos showed that needle-like F-HAp crystals bad large aspect ratios and grew in bundles, which were similar to the crystals in human tooth enamel.The results provide available information on dental restoration.
To differentiate fine hyperdense dots mimicking microcalcifications from true microcalcifications on mammography. Mammograms showing hyperdense dots in ten patients (mean age, 59 years) were evaluated. Two radiologists were asked to differentiate with the naked eye the hyperdense dots seen on ten mammograms and proven microcalcifications seen on ten mammograms. Densitometry was also performed for all lesions and the contrast index was calculated. The shape and distribution of the hyperdense dots were evaluated and enquires were made regarding any history of breast disease and corresponding treatment. Biopsies were performed for two patients with hyperdense dots. Two radiologists made correct diagnoses in 19/20 cases(95%). The contrast index was 0.10-0.88 (mean 0.58) for hyperdense dots and 0.02-0.45 (mean 0.17) for true microcalcifications. The hyperdense dots were finer and homogeneously rounder than the microcalcifications. Distribution of the hyperdense dots was more superficial in subcutaneous fat (seven cases) and subareolar area (six cases). All ten patients with hyperdense dots had history of mastitis and abscesses and had been treated by open drainage (six cases) and/or folk remedy (four cases). In eight patients, herb patches had been attached. Biopsies of hyperdense dots did not show any microcalcification or evidence of malignancy. These hyperdense dots were seen mainly in older patients. Their characteristic density, shape, distribution and clinical history makes differential diagnosis from true microcalcifications easy and could reduce unnecessary diagnostic procedures such as surgical biopsy

Full Text Available Abstract Renal cell carcinoma constitutes about 3% of adult malignancies. It has a high metastatic potential associated with synchronous or metachronous metastatic disease. Further, it is known to metastasize mainly to the lung, bone, brain, liver, or adrenal glands. In very rare cases it can metastasize to the gallbladder mimicking acute cholecystitis on clinical exam. In this case we present a patient who developed a gallbladder metastasis five years after a renal cell carcinoma mimicking acute cholecystitis.

Partial traumatic hemipelvectomy is a devastating condition. Although by definition the affected limb is not totally transected from the trunk because of retained soft tissue, the reported mortality rate is actually higher than in complete traumatic hemipelvectomy. Between January 2000 and December 2011, a total of 917 patients were admitted to the authors' institution for pelvic fracture. Seven of these patients met the criteria for partial traumatic hemipelvectomy. All 7 patients had multiple associated injuries and met the criteria for Baskett class IV hypovolemic shock on arrival at the emergency department. The amount of bleeding was the greatest issue, and control of hemorrhage and rapid blood transfusion were the initial goals. Abdominal aorta balloon occlusion, laparotomy and packing, and pelvic external fixation were useful to control bleeding. Two patients died during the initial resuscitation phase. Angiography (digital subtraction or computed tomographic) was performed in 4 patients but did not provide any treatment-altering information. Limb preservation was attempted in 2 patients; both of these patients eventually required hindquarter amputation. One patient died, and the second patient survived after a difficult postoperative course. The best results were obtained in 3 patients who underwent completion of the hindquarter amputation within 24 hours of trauma. All patients became wheelchair dependent, and no patient was able to return to work. Early completion of hindquarter amputation after hemorrhaging has been controlled is recommended in patients with partial traumatic hemipelvectomy. Angiography did not prove useful in decision making. PMID:24200435

Full Text Available BACKGROUND: Patent ductus arteriosus (PDA is one of the most common forms of congenital heart disease. Mutations in transcription factor TFAP2B cause Char syndrome, a human disorder characterized by PDA, facial dysmorphysm and hand anomalies. Animal research data are needed to understand the mechanisms. The aim of our study was to elucidate the pathogenesis of Char syndrome at the molecular level. METHODOLOGY/PRINCIPAL FINDINGS: Gene expression of Tfap2b during mouse development was studied, and newborns of Tfap2b-deficient mice were examined to identify phenotypes. Gel shift assays had been carried out to search for Tfap2 downstream genes. Promoters of candidate genes were cloned into a reporter construct and used to demonstrate their regulation by Tfap2b in cell transfection. In situ hybridizations showed that the murine transcription factor Tfap2b was expressed during the entire development of mouse ductus arteriosus. Histological examination of ductus arteriosus from Tfap2b knockout mice 6 hours after birth revealed that they were not closed. Consequently, the lungs of Tfap2b(-/- mice demonstrated progressive congestion of the pulmonary capillaries, which was postulated to result secondarily from PDA. In addition, Tfap2b was expressed in the limb buds, particularly in the posterior limb field during development. Lack of Tfap2b resulted in bilateral postaxial accessory digits. Further study indicated that expressions of bone morphogenetic protein (Bmp genes, which are reported to be involved in the limb patterning and ductal development, were altered in limb buds of Tfap2b-deficient embryos, due to direct control of Bmp2 and Bmp4 promoter activity by Tfap2b. CONCLUSIONS/SIGNIFICANCE: Tfap2b plays important roles in the development of mouse ductus arteriosus and limb patterning. Loss of Tfap2b results in altered Bmp expression that may cause the heart-limb defects observed in Tfap2b mouse mutants and Char syndrome patients. The Tfap2b knockout
To assess the efficacy and safety of transcatheter closure (TCC) of patent ductus arteriosus (PDA) with severe pulmonary arterial hypertension (PHT). TCC of small and moderate-sized PDAs is well established. However, there is a paucity of data on TCC of large PDA with severe PHT. This is a retrospective observational study of 76 patients with large PDA and severe PHT who were referred for TCC. Multiple clinical and investigational parameters were evaluated to decide the reversibility of PHT. Following the TCC, patients were serially followed up to assess the efficacy and safety of closure and its impact on PHT. Of 76 patients, nine were found to have PDA with Eisenmenger's syndrome. Of remaining 67, two were thought to have irreversible PHT based on hemodynamic data obtained after balloon occlusion of the duct. Sixty five patients, who eventually underwent TCC of PDA, had a median age of 9.1 years (range 1 month to 40 years). The weight ranged between 2.5 to 62 kg (median 14 kg). The PDA size was 9.1 ± 4.6 mm. The mean systolic pulmonary artery pressure was 66.9 ± 15.3 mm Hg. Duct occluder was used in 63 and muscular ventricular septal defect closure device in 2. The follow up was available in 56 (86%) with a mean follow up period of 65 ± 34 months. All the patients had complete closure of the PDA at 6 months follow up. Mild obstruction of left pulmonary artery (n=3) and aortic isthmus flow (n=6) was noted at the time of discharge. During the follow up, partial or complete resolution of PHT was observed in all the patients in whom Doppler-derived right ventricular systolic pressure was recorded (available in 40 of 56 patients). TCC of large PDA with severe PHT and significant left to right shunt was found to be effective and safe in the short and intermediate term
Full Text Available Background: Transcatheter closure of patent ductus arteriosus (PDA has become an alternative treatment to surgery. We evaluated the long-term results of the transcatheter closure of PDA with the Amplatzer Duct Occluder (ADO in children.Methods: Between May 2004 and October 2012, 138 children with PDA (43 males and 95 females underwent transcatheter PDA closure. Clinical, electrocardiographic, echocardiographic, and hemodynamic data were assessed pre and postprocedurally and at follow-up.Results: The mean age of the patients at procedure was 3.53 ± 2.43 years (range = 1.1 to 9.5 years, mean weight was11.9±4.6 kg (range = 6 to 29 kg, median pulmonary end diameter of the PDA was 5 mm (range = 4 to 15 mm, and median diameter of the ADO was 8 mm (range = 6 to 16 mm. The mean follow-up time was 43.4 ± 23.5 months (range = 13.5 to98 months.The devices were successfully deployed in 136 (98.5% patients. Device embolization occurred in 2 patients, immediately in one patient and during the first postprocedural night in the other patient. The first patient had percutaneous device retrieval, followed by implantation of a larger device. The second patient had surgical device removal and PDA ligation. Immediately after device implantation, trivial to mild residual shunts were detected in 112 (80% patients; all the shunts, however, disappeared 24 hours after the procedure. One patient had left pulmonary artery stenosis with a gradient of 25 mm Hg at 24 hours', 40 mmHg at one month's, and 64 mmHg at 6 months' follow-up. There were no cases of late embolization, aortic obstruction, late hemolysis, infective endocarditis, or death.Conclusion: Transcatheter PDA closure with the ADO was safe and effective, with a high success rate at long-term follow-up.

Surgical ligation for patent ductus arteriosus (PDA) in extremely low birth weight infants (ELBWIs) has been shown a possible association with neurodevelopmental impairment (NDI) because of its invasiveness. However, we have undergone surgical ligation for ELBWIs immediately after cyclooxygenase inhibitor failed to close a hemodynamically significant PDA (hsPDA) to maintain proper systemic circulation. We aimed to determine the effect of surgical ligation for hsPDA on NDI in ELBWIs. In enrolled 71 ELBWIs, the clinical parameters, including the developmental quotient (DQ), were collected and compared among three groups that were divided by closure mode: spontaneous closure (n = 11), cyclooxygenase inhibitor therapy (n = 37) and surgical ligation (n = 23). No significant differences in DQ at the age of 36 months among the three groups were found: Median (interquartile range): 92.0 (31.0), 89.0 (22.0) and 92.0 (24.5), respectively. In a comparison between groups of DQ < 70 (n = 15) and DQ ≥ 70 (n = 56), a significant difference was found in the parameters related to prematurity (p < 0.05 for each): gestational age [23.9 (1.70) vs. 25.4 (2.50) weeks], birth weight [595 (183) vs. 714 (192) g], Apgar score < 5 (1 min) (67% vs. 36%), and laser photocoagulation for retinopathy of prematurity (73% vs. 43%), but there was no significant association with hsPDA. Therefore, we propose that surgical ligation for hsPDA in ELBWIs should be immediately carried out for preventing future neurodevelopmental deterioration if the cyclooxygenase inhibitor failed to close hsPDA.

We evaluated the distribution, age incidence and interval from injury to diagnosis of these lesions, and the frequency of new subdural lesions in each lesion. ASD...
Objectives: To evaluate clinical features, treatment and relationship to the time period between dislocation, reduction and early complications of traumatic dislocation of hip in children. Methods: Case series conducted at Jinnah Post Graduate Medical Centre Karachi from July 2005 to August 2009. Children with traumatic hip dislocation up to fifteen years of age who presented in last four years were included in this study. Their clinical information, etiology, associated injuries, duration, method of reduction and early complications are evaluated through emergency room proforma and indoor record. Follow up of patient was updated in outpatient department. Results: We had eight patients, six boys and two girls. Youngest 2.4 years and eldest was 12 years with mean age of 6.2 +- 3.8 years. All presented with posterior hip dislocation. Etiology was road traffic accident in two and history of fall in remaining six patients. Average duration of time between dislocation and reduction was 19 hours range 3-72 hours. Dislocated hips were reduced under General Anaesthesia in two patients and under sedation analgesia in six patients. No complications were noted in eight cases with mean 18.75 +- 13.23 months follows up. Conclusion: Traumatic hip dislocation in children is not rare. Slight trauma causes dislocation in younger age and immediate closed reduction and Immobilization reduces complications. (author

Brain areas implicated in the stress response include the amygdala, hippocampus, and prefrontal cortex. Traumatic stress can be associated with lasting changes in these brain areas. Traumatic stress is associated with increased cortisol and norepinephrine responses to subsequent stressors. Antidepressants have effets on the hippocampus that counteract the effects of stress. Findings from animal studies have been extended to patients with post-traumatic stress disorder (PTSD) showing smaller h...
The impact of trauma in the Irish healthcare setting is considerable. We present the results of a retrospective assessment of referrals to a Neurophysiology department for suspected traumatic nerve injury. A broad range of traumatic neuropathies was demonstrated on testing, from numerous causes. We demonstrate an increased liklihood of traumatic nerve injury after fracture \\/ dislocation (p = 0.007). Our series demonstrates the need for clinicians to be aware of the possibility of nerve injury post trauma, especially after bony injury.

Traumatic cataract is due to lens damage when mechanical, irradiative, electrical or chemical agents injury the globe. The appearance of a traumatic cataract is typically short and unilateral with rare spontaneous resolution and often involves other ocular anatomical areas. Medico-legal evaluation of the appearance and the consequences of a traumatic cataract requires a correct methodological approach with the support of qualified ophthalmological competences.

The relationship between exposure to traumatic events and traumatic grief and the role of mediating and moderating variables [peritraumatic distress, post traumatic stress disorder (PTSD) symptoms and symptoms of depression] were studied in survivors of the genocide of Batutsi in Rwanda in 1994. One hundred and two survivors (70 women, mean age 45 ± 7.53 years) participated in this retrospective study. All of them had lost a member of their family. The severity of traumatic exposure (Comprehensive Trauma Inventory), peritraumatic distress (Peritraumatic Distress Inventory), current PTSD symptoms (PTSD Checklist), depressive symptoms (Beck Depression Inventory) and traumatic grief symptoms (Inventory of Traumatic Grief) was evaluated. A hierarchical multiple regression analysis was then conducted to examine the relative contribution of each variable to the symptoms of traumatic grief. The severity of traumatic exposure was related to traumatic grief symptoms (B=0.06, R=0.6, R(2) =0.36 and ß=0.6, t=7.54, p=0.00). The Baron and Kenny procedure (1986) (including three separate regressions), along with the Sobel test, was used to test mediation effects. Peritraumatic distress and PTSD symptoms may be mediating variables between traumatic exposure and traumatic grief. Traumatic grief is a complex but assessable entity, where previous distress and suffering result from both psychological trauma and the loss of a loved one. PMID:22282057

Munchausen syndrome is a disorder in which patients intentionally produce symptoms mimicking physical or psychiatric illnesses with the aim to assume the sick role and to gain medical attention. Once a patient receives a Munchausen syndrome diagnosis every complaint made thence tends to be regarded with scepticism by clinical staff. However, it is possible that a bona fide illness, which might be disregarded, may coexist in these patients. We report a case of MS mimicking psychiatric disease with concomitant genuine acute physical illness. Despite the initial doubts about the veracity of the latter, due to its prompt recognition, treatment was successful. PMID:22798096
Full Text Available Traumatic thoracic aortic rupture is a life-threatening condition; aortic isthmus is the most common site of rupture, but in rare cases traumatic injury can localize elsewhere, such as at aortic arch or at the level of the diaphragm. In the past few years, endovascular treatment of traumatic aortic injury became a safe procedure, with lower mortality and complication, if compared with open surgery. We report a case of a 40-year-old-man admitted to emergency department after a violent car crash in which an aortic traumatic double rupture was successfully treated with two endovascular stent-grafts coverage.

Traumatic brain injury is a global health concern and is the leading cause of traumatic morbidity and mortality in children. Despite a lower overall mortality than in adult traumatic brain injury, the cost to society from the sequelae of pediatric traumatic brain injury is very high. Predictors of poor outcome after traumatic brain injury include altered systemic and cerebral physiology, including altered cerebral hemodynamics. Cerebral autoregulation is often impaired following traumatic bra...

Gossypiboma is an inflammatory pseudomass formed by a retained surgical sponge or gauze with reactive tissue after surgery. Gossypiboma has been reported most frequently after abdominal or thoracic surgery. As such, gossypiboma following brain surgery is very rare. We report a case of gossypiboma mimicking tumor recurrence in the brain after a craniotomy and surgical excision of a low grade astrocytoma.
Full Text Available Unexpected extreme sudden traumatic stressor may cause post-traumatic stress disorder (PTSD. Important traumatic events include war, violent personal assault (e.g., sexual assault, and physical attack, being taken hostage or kidnapped, confinement as a prisoner of war, torture, terrorist attack, severe car accidents, and natural disasters. In childhood age sexual abuse or witnessing serious injuries or unexpected death of a beloved one are among important traumatic events.PTSD can be categorized into two types of acute and chronic PTSD: if symptoms persist for less than three months, it is termed “acute PTSD,” otherwise, it is called “chronic PTSD.” 60.7% of men and 51.2% of women would experience at least one potentially traumatic event in their lifetime. The lifetime prevalence of PTSD is significantly higher in women than men. Lifetime prevalence of PTSD varies from 0.3% in China to 6.1% in New Zealand. The prevalence of PTSD in crime victims are between 19% and 75%; rates as high as 80% have been reported following rape. The prevalence of PTSD among direct victims of disasters was reported to be 30%–40%; the rate in rescue workers was 10%–20%. The prevalence of PTSD among police, fire, and emergency service workers ranged from 6%–32%. An overall prevalence rate of 4% for the general population, the rate in rescue/recovery occupations ranged from 5% to 32%, with the highest rate reported in search and rescue personnel (25%, firefighters (21%, and workers with no prior training for facing disaster. War is one of the most intense stressors known to man. Armed forces have a higher prevalence of depression, anxiety disorders, alcohol abuse and PTSD. High-risk children who have been abused or experienced natural disasters may have an even higher prevalence of PTSD than adults.Female gender, previous psychiatric problem, intensity and nature of exposure to the traumatic event, and lack of social support are known risk factors for work

More than one-half million patients are hospitalized annually for traumatic brain injury (TBI). One-quarter demonstrate sleep-disordered breathing, up to 50% experience insomnia, and half have hypersomnia. Sleep disturbances after TBI may result from injury to sleep-regulating brain tissue, nonspecific neurohormonal responses to systemic injury, ICU environmental interference, and medication side effects. A diagnosis of sleep disturbances requires a high index of suspicion and appropriate testing. Treatment starts with a focus on making the ICU environment conducive to normal sleep. Treating sleep-disordered breathing likely has outcome benefits in TBI. The use of sleep promoting sedative-hypnotics and anxiolytics should be judicious. PMID:26118920
Traumatic lesions of the hip in athletes may be clinically challenging because of the overlap in clinical presentation due to differing pathologies and the presence of multiple injuries. Imaging of the hip in the athlete has undergone a recent resurgence of interest and understanding related to the increasing accessibility and use of hip arthroscopy, which expands the treatment options available for intra-articular pathology. MR imaging and MR arthrography have a unique role in diagnosis of these pathologies, guiding the surgeon, arthroscopist, and referring clinician in their management of bony and soft tissue injury.
Traumatic subarachnoid-pleural fistulas are rare. The authors found nine cases reported since 1959. Seven have been secondary to trauma and two following thoracotomy. One patient's death is thought to be directly related to the fistula. The diagnosis should be suspected in patients with a pleural effusion and associated vertebral trauma. The diagnosis can usually be confirmed with contrast or radioisotopic myelography. Successful closure of the fistula will usually occur spontaneously with closed tube drainage and antibiotics; occasionally, thoracotomy is necessary to close the rent in the dura

Morel-Lavallee seroma (MLS) or post-traumatic pseudocyst is a soft tissue seroma developing due to closed degloving injury by a shearing force that causes separation of subcutaneous fatty layer from the deeper muscular fascia resulting in collection of fluid in the created space. Presentation is usually fluctuant swelling following history of injury. More frequently described in orthopaedic literature, it occurs more commonly over gluteal and trochanteric regions, knee and flanks with occurrence over back, thorax being a rare entity. Despite mimicking several other similar presenting conditions, diagnosis of MLS can be made by meticulous history and physical examination with classical findings on ultrasonography, CT scan and MRI. Treatment modality may vary from conservative management to open surgical debridement of the wound with percutaneous aspiration and sclerodhesis forming useful adjuncts to conservative management.

Full Text Available Abstract We present a case of post-traumatic diaphragmatic herniation of the liver, which mimicked an intrathoracic tumor. After an automobile accident, the patient underwent thoracotomies for hemothorax and lung cancer in the right chest. Seven months later, computed tomography (CT demonstrated a round tumor in the thorax adjacent to the right diaphragm with a higher density than the liver parenchyma. An intrathoracic tumor including a primary or metastatic lung cancer was suspected. However, positron emission tomography (PET showed that the uptake of fluorine-18-fluorodeoxyglucose (FDG was identical to that in the liver, and the tumor appeared to be contiguous with the liver. Thus, we suspected liver herniation. Core needle biopsy revealed liver cells without neoplastic tissue. Upon surgical exploration, herniation of the liver was found and repaired. PET was helpful in providing morphological and functional information leading to accurate diagnosis of liver herniation in this unusual case.
Patent ductus arteriosus (PDA) represents 10%-20% of all congenital heart diseases. Percutaneous transcatheter device closure of PDA has been an effective alternative to surgical treatment and has been increasingly becoming the treatment of choice for most PDAs in children and adults. The indication for percutaneous closure of PDA has been further expanded with the development of domestic devices in China and almost all the patients with PDA can be cured by this therapy. This chapter will systematically describe the indications, contraindications for percutaneous PDA occlusion, how to close PDAs by using coils and umbrella devices, procedural complications and preventions. How to treat infant PDA, PDA with severe pulmonary arterial hypertension as well as the post-surgery residual shunt will be also discussed in detail in this chapter. (authors)
Full Text Available PHACE association is a rare neurocutaneous condition in which facial hemangiomas associate with a spectrum of posterior fossa malformations, arterial cerebrovascular anomalies, cardiovascular anomalies, and eye anomalies. We reported a case of PHACE association in a premature infant showing facial, intracranial, and oropharyngeal hemangiomas with evidence of the Dandy-Walker variant and complicated cardiovascular anomalies, including a right-sided aortic arch and an atypical patent ductus arteriosus arising from a tortuous left subclavian artery. To our knowledge, intracranial hemangiomas are rare in PHACE association, and a concomitant oropharyngeal hemangioma has not been previously reported in the PHACE association literature. In infants presenting with large, plaque-like facial hemangiomas, it is important to conduct active cardiovascular and neurological evaluations. Special attention should be given to the laryngoscopic examination to search for additional hemangiomas in the airway.
The authors report their experience in 144 patients with traumatic brachial plexus injury who underwent Direct Cervical Myelography (DCM). Sometimes the diagnostic investigation was completed by CT. Various myelographic patterns are described: pseudomeningocele, missing sheet of the root, scarring lesions. In 9 cases only, myelography was not sufficient to provide a complete diagnosis. The examination showed all plexus roots lacerated in 14 patients, a monoradicular lesion in 75 cases, and no lesion in 26 cases. Twenty-one out of the 26 negative cases were confirmed during surgery, while in 2 patients an intracanalar injury was found, which had not been detected due to the presence of scars. Scars often compress healty roots, and may mask intracanalar injuries. In such cases, and when the spinal cord stretches towards the side of the lesion, Myelo-CT can be useful. DCM proved to be an extremely sensitive and specific method, which can be used as a first-choice radiological procedure in the study of traumatic injuries of the brachial plexus

Visual impairment following head injury may be an enigma especially if the onset of symptoms were to be few days after the actual trauma and the bias arising out of the initial normal ophthalmological examination is not neutralised by unbiased repeated formal clinical evaluation aided with electrophysiology. We report and discuss here a 32-year-old lady with delayed onset of indirect traumatic visual loss with anaemia who failed to improve after blood transfusion but improved immediately following steroid therapy seven days after trauma. Though steroids have not been shown to have a significant contribution on outcomes following Traumatic optic neuropathy, this report rekindles its role in delayed progressive visual loss following head trauma and the need to re-analyse the role of steroids in patients with delayed progressive visual disturbance following head injury excluding those with acute onset symptoms in view of different pathologies in both these presentations. This paper also highlights potential mechanisms for the two major types of presentation. PMID:27134913
Traumatic diaphragmatic injury (TDI) is relatively rare condition, and is associated with high rates of morbidity and mortality. TDI usually results from blunt trauma and penetrating trauma. The majority causes of blunt TDI are victims of motor vehicle accidents. The incidence rates of TDI is unknown because of it can be overlooked if it is unsuspected with non-specific radiological and clinical findings. The mortality rates associated with blunt and penetrating TDI are affected by the severity of concurrent organ injuries. The diagnoses of TDI are frequently missed in the post-traumatic assessment because of non-specific symptoms or physical findings. When the site of trauma is in the abdomen, there will be high rate of an intra-abdominal organ injury. Furthermore, when the site of trauma is in the chest, there will be the abdominal organ injury in 50%.Surgical operation should be performed as soon as possible for concomitant injuries. Diaphragmatic repair can be performed using laparotomy, thoracotomy, or both approaches. Primary suture of the diaphragm can be performed in the majority of TDI patients. The outcome of post TDI depends on concurrent organ injury. In case of emergency, it is important to take an appropriate diagnosis and treatment for any concomitant injuries. PMID:26197916

Traumatic brain injury (TBI) treatment is now focused on the prevention of primary injury and reduction of secondary injury. However, no single effective treatment is available as yet for the mitigation of traumatic brain damage in humans. Both chemical and environmental stresses applied before injury, have been shown to induce consequent protection against post-TBI neuronal death. This concept termed “preconditioning” is achieved by exposure to different pre-injury stressors, to achieve the induction of “tolerance” to the effect of the TBI. However, the precise mechanisms underlying this “tolerance” phenomenon are not fully understood in TBI, and therefore even less information is available about possible indications in clinical TBI patients. In this review we will summarize TBI pathophysiology, and discuss existing animal studies demonstrating the efficacy of preconditioning in diffuse and focal type of TBI. We will also review other non-TBI preconditionng studies, including ischemic, environmental, and chemical preconditioning, which maybe relevant to TBI. To date, no clinical studies exist in this field, and we speculate on possible futureclinical situation, in which pre-TBI preconditioning could be considered. PMID:24323189

Objective Following traumatic brain injury (TBI),brain tissue that surrounding the regional primary lesion is known as traumatic penumbra; this region may undergo secondary injury and is considered to have the potential to recover.This review aimed to reveal the existence and significance of traumatic penumbra by analyzing all relevant studies concerning basic pathologic changes and brain imaging after TBI.Data sources We collected all relevant studies about TBI and traumatic penumbra in Medline (1995 to June 2013) and ISI (1997 to March 2013),evaluated their quality and relevance,then extracted and synthesized the information.Study selection We included all relevant studies concerning TBI and traumatic penumbra (there was no limitation of research design and article language) and excluded the duplicated articles.Results The crucial pathological changes after TBI include cerebral blood flow change,cerebral edema,blood-brain barrier damage,cell apoptosis and necrosis.Besides,traditional imaging method cannot characterize the consequences of CBF reduction at an early stage and provides limited insights into the underlying pathophysiology.While advanced imaging technique,such as diffusion tensor imaging (DTI) and positron emission tomography (PET),may provide better characterization of such pathophysiology.Conclusions The future of traumatic brain lesions depends to a large extent on the evolution of the penumbra.Therefore,understanding the formation and pathophysiologic process of the traumatic penumbra and its imaging research progress is of great significant for early clinical determination and timely brain rescue.

Migrating bats have increased mortality near moving turbine blades at wind farms. The authors evaluated competing hypotheses of barotrauma and traumatic injury to determine the cause. They first examined the utility of lungs from salvaged bat carcasses for histopathologic diagnosis of barotrauma and studied laboratory mice as a model system. Postmortem time, environmental temperature, and freezing of carcasses all affected the development of vascular congestion, hemorrhage, and edema. These common tissue artifacts mimicked the diagnostic criteria of pulmonary barotrauma; therefore, lung tissues from salvaged bats should not be used for barotrauma diagnosis. The authors next compared wind farm (WF) bats to building collision (BC) bats collected near downtown Chicago buildings. WF bats had an increased incidence in fracture cases and specific bone fractures and had more external lacerations than BC bats. WF bats had additional features of traumatic injury, including diaphragmatic hernia, subcutaneous hemorrhage, and bone marrow emboli. In summary, 73% (190 of 262) of WF bats had lesions consistent with traumatic injury. The authors then examined for ruptured tympana, a sensitive marker of barotrauma in humans. BC bats had only 1 case (2%, 1 of 42), but this was attributed to concurrent cranial fractures, whereas WF bats had a 20% (16 of 81) incidence. When cases with concurrent traumatic injury were excluded, this yielded a small fraction (6%, 5 of 81) of WF bats with lesions possibly consistent with barotrauma etiology. Forensic pathology examination of the data strongly suggests that traumatic injury is the major cause of bat mortality at wind farms and, at best, barotrauma is a minor etiology. PMID:22291071

An opportunity exists today for cross-cutting research utilizing advances in materials science, immunology, microbial pathogenesis, and computational analysis to effectively design the next generation of adjuvants and vaccines. This study integrates these advances into a bottom-up approach for the molecular design of nanoadjuvants capable of mimicking the immune response induced by a natural infection but without the toxic side effects. Biodegradable amphiphilic polyanhydrides possess the unique ability to mimic pathogens and pathogen associated molecular patterns with respect to persisting within and activating immune cells, respectively. The molecular properties responsible for the pathogen-mimicking abilities of these materials have been identified. The value of using polyanhydride nanovaccines was demonstrated by the induction of long-lived protection against a lethal challenge of Yersinia pestis following a single administration ten months earlier. This approach has the tantalizing potential to catalyze the development of next generation vaccines against diseases caused by emerging and re-emerging pathogens.

Bandura's Multidimensional Scales of Perceived Self-Efficacy (MSPSE) were administered to three matched groups of adolescents. The first group met diagnostic criteria for PTSD. The second had been exposed to qualitatively and quantitatively similar stressors and did not meet criteria for PTSD (traumatized PTSD negatives). The third group consisted of non-traumatized controls. Data analysis revealed that the adolescents with PTSD had appreciably lower self-efficacy ratings on eight of the nine subtests that comprise the MSPSE. Non-significant differences were observed when the MSPSE subtest scores of the traumatized PTSD negatives and controls were compared. PMID:7654163
