    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. 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.

  8. Post-traumatic heterotopic ossification of distal tibiofibular syndesmosis mimicking a surface osteosarcoma

    International Nuclear Information System (INIS)

    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

    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.

  16. Transcatheter Device Closure of Patent Ductus Arteriosus

    International Nuclear Information System (INIS)

    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)

    2011-01-01

    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.

  7. Frequency of etiological factors leading to patent ductus arteriosus

    International Nuclear Information System (INIS)

    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)

    2016-01-01

    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

    2013-01-01

    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

Methods This observational study using repeated measurements on premature infants with PDA detected at days 2-3 of life was undertaken in Cipto Mangunkusumo Hospital and Fatmawati Hospital, Jakarta, from April to May 2014. The PDA was diagnosed using 2-D echocardiography and PGE2 levels were measured by immunoassay. Pearson’s correlation test was used to evaluate a possible correlation between PGE2 level and DA diameter. Results Thirty-three premature infants of median gestational age 31 (range 28-32 weeks and median birth weight 1,360 (range 1,000-1,500 grams were enrolled. Almost two-thirds of the subjects were male. Almost all (30/33 subjects had spontaneous DA closure before the age of 10 days. Subjects’ mean DA diameter was 2.9 (SD 0.5 mm with maximum flow velocity of 0.2 (SD 0.06 cm/sec, and left atrial-to-aortic root ratio (LA/Ao of 1.5 (SD 0.2. Their mean PGE2 levels at the ages of 2-3, 5-7, and after 10 days were 5,238.6 (SD 1,225.2, 4,178.2 (SD 1,534.5, and 915.2 (SD 151.6 pg/mL, respectively. The PGE2 level at days 2-3 was significantly correlated with DA diameter (r = 0.667; P < 0.001, but not at days 5-7 (r = 0.292; P = 0.105 or at day 10 (r = 0.041; P = 0.941. Conclusion There is a strong, positive correlation between the PGE2 level and DA diameter in preterm infants at 2-3 days of age. However, there is no significant correlation between PGE2 level and persistence of PDA.

  19. Evaluation of radioisotopic angiocardiography in patent ductus arteriosus

    International Nuclear Information System (INIS)

    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.&lt;br&gt; 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.&lt;br&gt;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. &lt;br&gt;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.

  3. Stenting the ductus arteriosus: Case selection, technique and possible complications

    International Nuclear Information System (INIS)

    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

  4. 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?

    International Nuclear Information System (INIS)

    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.)

    International Nuclear Information System (INIS)

    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)

    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 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

    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

    2015-01-01

    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.

    2011-01-01

    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.

  4. Black hole mimickers: Regular versus singular behavior

    International Nuclear Information System (INIS)

    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

  5. Double-chambered right ventricle, ventricular septal defect, patent ductus arteriosus in a dog

    International Nuclear Information System (INIS)

    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)

    2015-05-01

    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...

    2011-09-01

    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 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

    2015-10-01

    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.

  10. Percutaneous closure of patent ductus arteriosus in interrupted inferior caval vein through femoral vein approach

    International Nuclear Information System (INIS)

    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

    2010-11-01

    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.

    2014-08-14

    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.

    2011-12-01

    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.

  8. Transcatheter closure of re-canalized patent ductus arteriosus after surgical ligation

    International Nuclear Information System (INIS)

    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

  10. Retrograde wire-track based percutaneous transcatheter closure of persistent duct arteriosus: a new application

    International Nuclear Information System (INIS)

    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.

    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

  18. Early results of transcatheter closure of patent ductus arteriosus: retrospective study of 61 patients

    International Nuclear Information System (INIS)

    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

Era 1 (January 2005 to December 2007 featured traditional management with indomethacin and/or surgical ligation used early to close PDAs; Era 2 (January 2008 to June 2009 featured fluid restriction and watchful waiting for PDA closure, limiting indomethacin or surgical ligation to only those infants with large PDAs needing significant respiratory support.Results: Era 2 infants (n = 129, mean ± standard deviation 27 ± 2 weeks received less and later indomethacin and less Day 1–28 total fluids as compared to Era 1 infants (n = 240, mean ± standard deviation 27 ± 2 weeks. The Chronic Lung Disease (CLD rate was higher in Era 2 (48% versus 34%, P < 0.01 as was the combined outcome of Death after Day 7 or CLD (57% versus 42%, P < 0.01. 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

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

  17. Post-traumatic osteomyelitis

    International Nuclear Information System (INIS)

    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.)

    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.

    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.

  10. Acute traumatic patellar dislocation.

    Duthon, V B

    2015-02-01

    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

  17. The exploration of the closure of patent ductus arteriosus with Amplatzer occluder through single venous approach under ultrasound monitoring

    International Nuclear Information System (INIS)

    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)

  18. Hybrid management of a large atrial septal defect and a patent ductus arteriosus in an infant with chronic lung disease

    International Nuclear Information System (INIS)

    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

    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.

    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.

  9. Hyperdense dots mimicking microcalcifications : Mammographic findings

    International Nuclear Information System (INIS)

    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

    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

  20. Transcatheter closure of large patent ductus arteriosus with severe pulmonary arterial hypertension: Short and intermediate term results

    International Nuclear Information System (INIS)

    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.

  5. Traumatic hip dislocations in children

    International Nuclear Information System (INIS)

    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

    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 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

    2015-07-01

    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

    Singh, Anshuman; Anand, Akshay; Mittal, Sanchit; Sonkar, Abhinav Arun

    2016-01-01

    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.

  15. Interventional treatment of common congenital heart diseases: the common view of Chinese medical experts. Part Three; interventional treatment of patent ductus arteriosus

    International Nuclear Information System (INIS)

    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.

  17. Traumatic injuries of brachial plexus

    International Nuclear Information System (INIS)

    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

    This investigation sought to determine if exposure to exceptional stress is associated with academic deficits or whether academic deficits are specifically associated with post-traumatic stress disorder (PTSD). In order to address these questions, the Metropolitan Achievement Test (MAT) as well as a measure of intelligence were administered to three groups of Lebanese adolescents. The first group met diagnostic criteria for PTSD. The second group had been exposed to qualitatively and quantitatively similar stressors but did not meet diagnostic criteria for PTSD. The third group consisted of nontraumatized controls. Data analysis using IQ as a covariate determined that the MAT scores of the PTSD subjects were significantly lower than the scores of the stress exposed PTSD negatives and controls. No significant differences were observed when the MAT scores of the stress exposed PTSD negatives and controls were compared. PMID:9149452

    2016-01-01

    There is a lack of evidence-based approach regarding the best practice for airway management in patients with a traumatized airway. General recommendations for the management of the traumatized airway are summarized in table 5. Airway trauma may not be readily apparent, and its evaluation requires a high level of suspicion for airway disruption and compression. For patients with facial trauma, control of the airway may be significantly impacted by edema, bleeding, inability to clear secretions, loss of bony support, and difficulty with face mask ventilation. With the airway compression from neck swelling or hematoma, intubation attempts can further compromise the airway due to expanding hematoma. For patients with airway disruption, the goal is to pass the tube across the injured area without disrupting it or to insert the airway distal to the injury using a surgical approach. If airway injury is extensive, a surgical airway distal to the site of injury may be the best initial approach. Alternatively, if orotracheal intubation is chosen, spontaneous ventilation may be maintained or RSI may be performed. RSI is a common approach. Thus, some of the patients intubated may subsequently require tracheostomy. A stable patient with limited injuries may not require intubation but should be watched carefully for at least several hours. Because of a paucity of evidence-based data, the choice between these approaches and the techniques utilized is a clinical decision depending on the patient's condition, clinical setting, injuries to airway and other organs, and available personnel, expertise, and equipment. Inability to obtain a definitive airway is always an absolute indication for an emergency cricothyroidotomy or surgical tracheostomy. PMID:26517857

    2016-01-01

    Sleep disturbances are frequently identified following traumatic brain injury, affecting 30%-70% of persons, and often occur after mild head injury. Insomnia, fatigue, and sleepiness are the most frequent sleep complaints after traumatic brain injury. Sleep apnea, narcolepsy, periodic limb movement disorder, and parasomnias may also occur after a head injury. In addition, depression, anxiety, and pain are common brain injury comorbidities with significant influence on sleep quality. Two types of traumatic brain injury that may negatively impact sleep are acceleration/deceleration injuries causing generalized brain damage and contact injuries causing focal brain damage. Polysomnography, multiple sleep latency testing, and/or actigraphy may be utilized to diagnose sleep disorders after a head injury. Depending on the disorder, treatment may include the use of medications, positive airway pressure, and/or behavioral modifications. Unfortunately, the treatment of sleep disorders associated with traumatic brain injury may not improve neuropsychological function or sleepiness. PMID:26929626

  6. Unilateral traumatic oculomotor nerve paralysis

    International Nuclear Information System (INIS)

    The present authors report a case of unilateral traumatic oculomotor nerve paralysis which shows interesting CT findings which suggest its mechanism. A 60-year-old woman was admitted to our hospital with a cerebral concussion soon after a traffic accident. A CT scan was performed soon after admission. A high-density spot was noted at the medial aspect of the left cerebral peduncle, where the oculomotor nerve emerged from the midbrain, and an irregular, slender, high-density area was delineated in the right dorsolateral surface of the midbrain. Although the right hemiparesis had already improved by the next morning, the function of the left oculomotor nerve has been completely disturbed for the three months since the injury. In our case, it is speculated that an avulsion of the left oculomotor nerve rootlet occurred at the time of impact as the mechanism of the oculomotor nerve paralysis. A CT taken soon after the head injury showed a high-density spot; this was considered to be a hemorrhage occurring because of the avulsion of the nerve rootlet at the medial surface of the cerebral peduncle.

  7. Sterile post-traumatic immunosuppression.

    Science.gov (United States)

    Islam, Md Nahidul; Bradley, Benjamin A; Ceredig, Rhodri

    2016-04-01

    After major trauma, the human immune system initiates a series of inflammatory events at the injury site that is later followed by suppression of local inflammation favoring the repair and remodeling of the damaged tissues. This local immune response involves complex interactions between resident cells such as macrophages and dendritic cells, soluble mediators such as cytokines and chemokines, and recruited cells such as neutrophils, monocytes and mesenchymal stromal cells. If of sufficient magnitude, these initial immune responses nevertheless have systemic consequences resulting in a state called post-traumatic immunosuppression (PTI). However, controversy exists regarding the exact immunological changes occurring in systemic compartments triggered by these local immune responses. PTI is one of the leading causes of post-surgical mortality and makes patients vulnerable to hospital-acquired infections, multiple organ failure and many other complications. In addition, hemorrhage, blood transfusion, immunesenescence and immunosuppressant drugs aggravate PTI. PTI has been intensively studied, but published results are frequently cloudy. The purpose of this review is to focus on the contributions made by different responsive modalities to immunosuppression following sterile trauma and to try to integrate these into an overall scheme of PTI.

  8. Chronic Traumatic Encephalopathy: A Review

    Directory of Open Access Journals (Sweden)

    Michael Saulle

    2012-01-01

    Full Text Available Chronic traumatic encephalopathy (CTE is a progressive neurodegenerative disease that is a long-term consequence of single or repetitive closed head injuries for which there is no treatment and no definitive pre-mortem diagnosis. It has been closely tied to athletes who participate in contact sports like boxing, American football, soccer, professional wrestling and hockey. Risk factors include head trauma, presence of ApoE3 or ApoE4 allele, military service, and old age. It is histologically identified by the presence of tau-immunoreactive NFTs and NTs with some cases having a TDP-43 proteinopathy or beta-amyloid plaques. It has an insidious clinical presentation that begins with cognitive and emotional disturbances and can progress to Parkinsonian symptoms. The exact mechanism for CTE has not been precisely defined however, research suggest it is due to an ongoing metabolic and immunologic cascade called immunoexcitiotoxicity. Prevention and education are currently the most compelling way to combat CTE and will be an emphasis of both physicians and athletes. Further research is needed to aid in pre-mortem diagnosis, therapies, and support for individuals and their families living with CTE.

Characterization of an example phantom revealed acoustic properties consistent with those found in fibrous tissues. At 20 MHz, the velocity measured parallel to the microstructure orientation of 1555 ms(-1) was significantly greater than that perpendicular to the microstructure of 1537 ms(-1). The attenuation coefficient was measured to be 5 dBxmm(-1) and proportional to the 1.6 power of frequency, which is in good agreement with that for normal human myocardium. PMID:20639144

    The case of a 23-year-old female treated with aggressive high-dose therapy for Burkitt's lymphoma is reported. A positron emission tomography and computed tomography scan after completion of chemotherapy revealed a residual hypermetabolic lesion in the right pelvic cavity. A pelvic magnetic resonance imaging scan showed circumferential wall thickening at the tip of the appendix. A laparoscopic exploration and appendectomy were performed, and a pathologic examination of the resected appendix revealed xanthogranulomatous appendicitis. This is a rare case of a xanthogranulomatous appendicitis mimicking remnant Burkitt's lymphoma after completion of chemotherapy.

  12. Primary hepatic tuberculosis mimicking intrahepatic cholangiocarcinoma: report of two cases

    Science.gov (United States)

    2015-01-01

    Hepatic tuberculosis (TB) is usually associated with pulmonary or miliary TB, but primary hepatic TB is very uncommon even in countries with high prevalence of TB. The clinical manifestation of primary hepatic TB is atypical and imaging modalities are unhelpful for differential diagnosis of the liver mass. Image-guided needle biopsy is the best diagnostic method for primary hepatic TB. In the cases presented here, we did not perform liver biopsy because we believed the liver masses were cholangiocarcinoma, but primary hepatic TB was ultimately confirmed by postoperative pathology. Here we report two cases of patients who were diagnosed with primary hepatic TB mimicking mass-forming intrahepatic cholangiocarcinoma. PMID:26236700

    Full Text Available A cutaneous horn is a general name for cornified material protruding from skin. On the other hand, polydactyly is a common congenital anomaly of the hand and foot which is characterized by extra finger or toe. A cutaneous horn might mimick polydactyly by resembling an extra toe. Hereby, we present a 72-year-old white Caucasian male with an extra toe-like projection on his fourth toe. Initially, polydactyly was suspected, however a cutaneous horn was also considered. The lesion was surgically removed. The histopathological examination of the specimen revealed hyperkeratosis, and thus confirmed the  lesion to be a cutaneous horn.

  15. Epithelioid sarcoma mimicking abscess: review of the MRI appearances

    International Nuclear Information System (INIS)

    A case of epithelioid sarcoma involving the soft tissue of the ankle is presented. The tumor was a hemorrhagic, fluid-filled, multiloculated lesion with inflammatory changes in the surrounding planes. Tuberculous abscess was diagnosed on the basis of the clinical picture, ultrasound and MRI findings. Surgical exploration of the ankle mass was carried out because of lack of local healing while the patient's general and pulmonary status improved on antituberculosis treatment. This was an unusual case of epithelioid sarcoma mimicking a multilocular abscess. (orig.)

    We report an interesting case in which overt aortic dissection mimicked two episodes of aortic intramural hematoma (IMH) (Stanford A, DeBakey I). This took place over the course of four days and had a major influence on the surgical treatment strategy. The first episode of IMH regressed completely within 15 hours after it was clinically diagnosed and verified using imaging techniques. The recurrence of IMH was detected three days thereafter, resulting in an urgent surgical intervention. Overt aortic dissection with evidence of an intimal tear was diagnosed intraoperatively.

    We herein describe a rare case of a 24-year-old man who presented with severe epigastralgia after consuming a considerable amount of broiled meat. Computed tomography revealed a cystic lesion adjacent to the distal stomach, with high intensity on T2-weighted magnetic resonance imaging. Upper endoscopy showed a cystic mass measuring 6 cm in diameter, mimicking a submucosal tumor adjacent to the pyloric valve, with duodenum invagination, characteristic of ball valve syndrome. Endoscopic ultrasonography showed that the lesion was contiguous through the first to the third layer of the stomach. Therefore, we performed distal gastrectomy. Pathology showed that the lesion was a gastric duplication cyst without malignancy. PMID:27580540

    Opportunistic subcutaneous fungal infections are increasing nowadays due to the growing number of medical conditions causing immunosuppression, especially organ transplant. The incidence rate of subcutaneous phaeohyphomycosis is very low. Most studies found are case reports. They showed a wide variation of clinical presentations. Pyrenochaeta romeroi, a fungus from the Dematiaceae group is a saprophyte found in soil and plants and a possible causative agent of phaeohyphomycosis. We present a rare case of subcutaneous phaeohyphomycosis caused by P. romeroi mimicking a synovial cyst in a diabetic patient.

    2016-08-01

    This research focused on secondary traumatization of wives and offspring of 115 male Vietnam veterans, a subsample from the National Vietnam Veterans Readjustment Study who had one or more children aged 6 to 16 years and had had a clinical interview. Traumatization was defined as meeting criteria for lifetime war-related posttraumatic stress disorder (PTSD). Secondary traumatization was operationalized by elevated scores on children's internalizing or externalizing behavior problems and on wives' demoralization. There was evidence of secondary traumatization in the veterans' sons (odds ratio [OR] = 20.31 for internalizing behavior problems). Current PTSD in the veterans was associated with demoralization in their wives or partners (β = 0.24), which in turn was associated with behavior problems in their daughters (ORs = 2.67 and 4.61 for internalizing and externalizing behavior problems, respectively; these were adjusted for veteran's PTSD). Demoralization of the wife or partner was also associated with current alcoholism in the veterans (β = 0.30, adjusting for veteran's PTSD). These associations were also adjusted for other veteran risk factors, including severity of combat exposure, involvement in harming civilians or prisoners, and prewar vulnerability. Even with the degree of secondary traumatization present, the veterans' children appeared at least as healthy as counterparts in the general population. PMID:27529559

    2016-02-01

    Full Text Available Mari Viola-Saltzman, Camelia Musleh Department of Neurology, NorthShore University HealthSystem, Evanston, IL, USA Abstract: Sleep disturbances are frequently identified following traumatic brain injury, affecting 30%–70% of persons, and often occur after mild head injury. Insomnia, fatigue, and sleepiness are the most frequent sleep complaints after traumatic brain injury. Sleep apnea, narcolepsy, periodic limb movement disorder, and parasomnias may also occur after a head injury. In addition, depression, anxiety, and pain are common brain injury comorbidities with significant influence on sleep quality. Two types of traumatic brain injury that may negatively impact sleep are acceleration/deceleration injuries causing generalized brain damage and contact injuries causing focal brain damage. Polysomnography, multiple sleep latency testing, and/or actigraphy may be utilized to diagnose sleep disorders after a head injury. Depending on the disorder, treatment may include the use of medications, positive airway pressure, and/or behavioral modifications. Unfortunately, the treatment of sleep disorders associated with traumatic brain injury may not improve neuropsychological function or sleepiness.

    2001-10-01

    Full Text Available We report a case of leptospirosis that occurred after elective surgery involving tendon transfer and shoulder arthroscopy. The disease mimicked hospital infection after orthopedic surgery and was at first misdiagnosed as post-operative sepsis. The patient was 60 year old female that developed sepsis with hypotension, shock, bleeding, jaundice and renal insufficiency 4 hours after surgery. Shock treatment procedures were performed and broad spectrum antibiotic therapy was used with coverage for bacteria acquired in hospitals. A careful investigation was carried out by the Hospital Infection Control Service in search of the possible source of the infection. After clinical evaluation by a specialist in infectious diseases, the hypothesis of leptospirosis was put forward based on clinical and epidemiological data. The hypothesis was later confirmed by the positive result of serological tests with the microagglutination method that yielded 1:800 and then 1:12,600 7 days later. This is the first reported case of leptospirosis manifest directly following surgery, mimicking postoperative sepsis.

  10. Role of prophylactic surgical ligation of patent ductus arteriosus in extremely low birth weight infants: Systematic review and implications for clinical practice

    International Nuclear Information System (INIS)

    To investigate the effectiveness and safety of prophylactic surgical ligation of patent ductus arteriosus (PDA) on mortality and morbidity of preterm infants weighing less than 1000 g at birth. The study conducted a systematic search of available database from 1996-2008. Retrieved articles were assessed for eligibility and data was abstracted independently by two reviewers. Decisions to include studies for review and the methodological quality of included studies were asssessed in duplicate based on predetermined criteria. No language restrictions were applied. Only one eligible study that enrolled 84 extremely low birth weight infants was identified. Prophylactic surgical ligation of PDA resulted in a statistically significant reduction of severe stage II or III necrotizing enterocolitis, [RR 0.25, 95% CI (0.08, 0.83), P value 0.02, number needed to treat 5]. The study, however, found no statistically significant difference in mortality, intraventricular hemorrhage, bronchopulmonary dysplasia, and retinopathy of prematurity. Current evidence does not support the use of prophylactic surgical ligation of PDA in the management of the preterm infants

    The juxtaposition of heart and gills in teleost fish means that the Windkessel function characteristic of the whole mammalian arterial tree has to be subserved by the extremely short ventral aorta and bulbus arteriosus. Over the functional pressure range, arteries from blue marlin (Makaira nigricans) and yellowfin tuna (Thunnus albacares) have J-shaped pressure-volume (P-V) loops, while bulbi from the same species have r-shaped P-V loops, with a steep initial rise followed by a compliant plateau phase. The steep initial rise in pressure is due to the geometry of the lumen. The interactions between radius, pressure and tension require a large initial pressure to open the bulbar lumen for flow. The plateau is due to the unique organization of the bulbar wall. The large elastin:collagen ratio, limited amount of collagen arranged circumferentially, lack of elastin lamellae and low hydrophobicity of the elastin itself all combine to lower stiffness, increase extensibility and allow efficient recoil. Even though the modulus of bulbus material is much lower than that of an artery, at large volumes the overall stiffness of the bulbus increases rapidly. The morphological features that give rise to the special inflation characteristics of the bulbus help to extend flow and maintain pressure during diastole. PMID:12939364

    2016-05-01

    Background Cyclo-oxygenase inhibitors (COX-I) treatment of patent ductus arteriosus (PDA) in very low birth weight (VLBW) infants during the early postnatal period is well established, but their use beyond early postnatal period is not well studied. Objective The objective of this study was to determine the effectiveness of postnatal COX-I for PDA treatment beyond 2 weeks of age in VLBW infants. Study Design A retrospective cohort of VLBW infants admitted to two tertiary NICUs between 1990 and 2008 were studied. Infants with symptomatic PDA were treated with COX-I and infants with failed medical treatment were candidates for surgical ligation. Effectiveness of COX-I treatment, measured by the need for surgical ligation, was compared between early (day of life [DOL] value: not significant). There were no significant differences in demographics or morbidities between the two groups. Conclusions In VLBW infants, late treatment of PDA with COX-I was as effective as early treatment. Trial of late COX-I treatment is warranted for symptomatic PDA before surgical treatment. PMID:26731181

  16. Traumatic intracranial aneurysms in children

    International Nuclear Information System (INIS)

    To describe the imaging findings of traumatic intracranial aneurysms (TICA) in children. Five boys aged 3-15 (mean, 7) years with surgically confirmed TICA were included in this study. All had a history of nonpenetrating head trauma, and they underwent precontrast CT imaging immediately after the injury and follow-up CR or MRI. In all cases, angiography revealed the presence of aneurysms, which at surgery were shown to be pseudoaneurysms with sever adhesions. Angiography demonstrated that all aneurysms were located in the anterior cerebral artery (ACA) or its branches. The precise locations were the A2 segment of the ACA, the site of origin of the callosomarginal artery or its first branch, or of the anterior internal frontal artery, or between the first and second branch of the pericallosal artery. In all patients, precontrast CT performed immediately after trauma depicted subarachnoid hemorrhage (SAH) in the anterior interhemispheric fissure (AIHF). Follow-up precontrast CT showed nodular high density around the anterior falx in three, recurrent SAH in the AIHF in two, and intracerebral hemorrhage (ICH) with intraventricular hemorrhage in two. In two patients with a nodular high-density lesion, nodular enhancement was demonstrated at postcontrast CT, and in one, follow-up MRI revealed a nodular signal void around the anterior falx; nodular enhancement was seen at postcontrast imaging, and MR angiogram depicted a saccular aneurysm. In one patient, MRI demonstrated infarction in the caudate nucleus and ACA territory. If, after head injury, an area of nodular high density is revealed by CT, or a signal void by MRI, or is SAH or ICH is present around the anterior falx, the possibility of TICA should be considered

    Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

    Full Text Available Traumatic diaphragmatic injury (DI is a unique clinical entity that is usually occult and can easily be missed. Their delayed presentation can be due to the delayed rupture of the diaphragm or delayed detection of diaphragmatic rupture, making the accurate diagnosis of DI challenging to the trauma surgeons. An emergency laparotomy and thorough exploration followed by the repair of the defect is the gold standard for the management of these cases. We report a case of blunt DI in an elderly gentleman and present a comprehensive overview for the management of traumatic injuries of the diaphragm.

  9. Traumatic dural laceration in a racing Greyhound

    International Nuclear Information System (INIS)

    Acute pelvic limb paralysis occurred in a racing Greyhound after a traumatic incident. During myelography, a dorsal laceration of the dura mater was detected at T12–13. Immediate hemilaminectomy was performed at T12–13, but neurologic status did not improve. At necropsy there was epidural and subdural hemorrhage at the T12–13 interspace, and malacia and swelling of the spinal cord at that level. Intramedullary hemorrhage, malacia, and free fibrocartilaginous material characterized histopathology of the lesion. Possible mechanisms of the traumatic disk extrusion are discussed

    Traumatic hemorrhagic shock (HS) is a severe outcome of traumatic injury that accounts for numerous traumatic deaths. In the process of traumatic HS, both hemorrhage and trauma can trigger a complex cascade of posttraumatic events that are related to inflammatory and immune responses, which may lead to multiple organ injury or even death. From a mechanistic perspective, systemic inflammation and organ injury are involved coagulation, the complement system, impaired microcirculation and inflammatory signaling pathways. In this review, we discuss the systemic inflammation and multiple organ injury in post-traumatic HS. PMID:25961533

    2009-01-01

    This paper presents an experimental research aiming to realize an artificial hind wing that can mimic the wing unfolding motion of Allomyrina dichotoma, an insect in coleopteran order. Based on the understanding of working principles of beetle wing folding/unfolding mechanisms, the hind wing unfolding motion is mimicked by a combination of creative ideas and state-of-art artificial muscle actuator. In this work, we devise two types of artificial wings and the successfully demonstrate that they can be unfolded by actuation of shape memory alloy wires to provide actuation force at the wing base and along the leading edge vein. The folding/unfolding mechanisms may provide an insight for portable nano/micro air vehicles with morphing wings.

    2011-05-01

    Amiodarone is a highly effective antiarrhythmic drug. Its long-term use may, however, lead to several adverse effects, with pulmonary toxicity being the most serious. The article presents the case of a 78-year-old woman with a history of cardiac surgery, who after 2 years of amiodarone therapy for prophylactic treatment of atrial fibrillation developed amiodarone pneumonitis mimicking an acute pulmonary edema. The patient failed to respond to diuretic therapy and several courses of anti-infective therapy. Differential diagnosis of different causes of pulmonary infiltrates did not demonstrate any other abnormality. Lung biopsy findings were consistent with the diagnosis of amiodarone pneumonitis. Given the widespread use of amiodarone as an antiarrhythmic agent, pneumologists and cardiologists should consider this important adverse effect as a differential diagnosis of pulmonary distress refractory to therapy in all patients treated with amiodarone who present with respiratory symptoms and pneumonia-like illness.

    2014-01-01

    Full Text Available Langerhans cell histiocytosis (LCH is a rare idiopathic disease characterized by the clonal proliferation of Langerhans cells. LCH affects five children per million population. The peak incidence is from 1 to 4 years of age. LCH involves the head and neck region quite commonly. Oral soft tissue lesions are also common. The differential diagnosis of oral LCH includes leukemia, neutropenia, prepubertal periodontitis, hypophosphatasia, fibrous dysplasia, and Papillon-Lefevre syndrome. The prognosis of LCH depends on early detection and appropriate management. Surgical management alone is used in 50% of cases with an additional 23% of the lesions being treated with both surgery and radiation therapy. A case of LCH in a 6-year-old girl involving the mid root level of developing first permanent molar with a floating developing tooth bud of permanent second molar mimicking an inflammation is reported.

    2011-01-01

    Full Text Available Ectopic ureter is one of the most common urinary tract anomalies. We, herein, present a case of a giant ureter with ectopic orifice, mimicking pelvic organ prolapse, which is the first in the literature. A 59-year-old female patient presenting with frequently recurrent urinary tract infection had grade 3 pelvic organ prolapse. On examination, the organ producing the appearance of prolapse was found to be a right ureter of giant size and was obstructed by a large stone at the distal segment. The proximal end of the ureter ended blindly. After exploration, the stone was removed, the ureter was detached from the urethra, and the lumen was tied off and cut 5 cm proximally. At 6 months postoperatively, the patient is being followed up without any clinical problems. In such cases with nonfunctioning renal segment draining proximally, the chance of cure can be obtained without a need for a comprehensive intervention such as total abdominal ureterectomy.

    Optical phantoms mimicking optical properties of real biotissues in the visible and IR spectral regions are developed based on measurements of the spectral characteristics of ex vivo samples of laboratory mouse biotissues. The phantoms are composed of aqueous solutions of Lipofundin, Indian ink and red ink with different spectral characteristics. The deviations of the measured absorption and scattering coefficients of phantoms in the wavelength range 480 – 580 nm from the corresponding values for real biotissues do not exceed 25% and 2%, respectively. For phantoms in the wavelength region 580 – 880 nm, the deviations of the absorption coefficient do not exceed 40% and the deviations of the scattering coefficient do not exceed 25%. These values, in general, fall within the range of variations for different individual mice of one strain.

    In this investigation, we report on a fabrication method of epineurium-mimicking tubular conduits based on electrodeposition from chitosan solution. The pre-enrichment of electrodeposition solution with hyaluronic acid and/or collagen components results in structures which structural, morphological, and physicochemical properties can be controlled. In order to determine the optimal composition of the initial chitosan solution resulting in conduits meeting the requirements imposed on peripheral nerve implants, we perform chemical, physical, and biological studies. Both the molecular weight of hyaluronic acid and the concentration of additives are found to be crucial for the final mechanical as well as biological performance of conduits. Because, the obtained structures show biocompatibility when contacting with a mouse hippocampal cell line (mHippoE-18), we further plan to test their application potential on an animal model.

    2013-02-01

    Full Text Available The bioimpedance of tissues under compression is a field in need of study. While biological tissues can become compressed in a myriad of ways, very few experiments have been conducted to describe the relationship between the passive electrical properties of a material (impedance/admittance during mechanical deformation. Of the investigations that have been conducted, the exodus of fluid from samples under compression has been thought to be the cause of changes in impedance, though until now was not measured directly. Using a soft tissue-mimicking phantom material (tofu whose passive electrical properties are a function of the conducting fluid held within its porous structure, we have shown that the mechanical behavior of a sample under compression can be measured through bioimpedance techniques.

    Various forms of hepatic actinomycosis can be observed on the imaging studies. We report here the imaging findings of three cases of hepatic actinomycosis, which presented as a solid mass mimicking a malignant tumor. With respect to their enhancement pattern on the contrast-enhanced CT and MR images, one case showed homogeneous and persistent enhancement throughout three phases, while the other two cases showed variable degrees of delayed enhancement with their own features during the portal and equilibrium phases, suggesting that they have abundant fibrosis at different stages. Also, normal vascular structures traversing the masses were noted in all three cases. One core needle biopsy and two surgical resections were performed, and the masses were pathologically proven to be hepatic actinomycosis. In conclusion, we need to be aware that a hepatic tumor with abundant fibrosis, in which the normal vasculature is traversing, can be diagnosed as hepatic actinomycosis.

    2015-08-01

    Protein toxins secreted from pathogenic bacteria and venomous animals rely on multiple mechanisms to overcome the cell membrane barrier to inflict their virulence effect. A promising therapeutic concept toward developing a broadly applicable anti-toxin platform is to administer cell membrane mimics as decoys to sequester these virulence factors. As such, lipid membrane-based nanoparticulates are an ideal candidate given their structural similarity to cellular membranes. This article reviews the virulence mechanisms employed by toxins at the cell membrane interface and highlights the application of cell-membrane mimicking nanoparticles as toxin decoys for systemic detoxification. In addition, the implication of particle/toxin nanocomplexes in the development of toxoid vaccines is discussed. PMID:25868452

    Malignant fibrous histiocytoma (MFH) is a pleomorphic mesenchynal sarcoma. It is uncommonly arises primarily from the intra-peritoneal cavity. Primary peritoneal MFH with tumor bleeding and rupture is rare. We describe the imaging features of a 70-year-old patient presenting with ruptured hemorrhagic peritoneal MFH at subhepatic area, accompanied by massive hemoperitoneum,mimicking a ruptured pedunculated hepatocellular carcinoma. Computed tomography (CT) revealed a large heterogeneous enhanced subhepatic mass with adjacent liver, gallbladder and colon invasion. Tumor hemorrhage and rupture complicated with peritoneal seeding and massive bloody ascites were also detected.Angiography showed a hypervascular tumor fed by enlarged right hepatic arteries, cystic artery and omental branches of gastroepiploic artery. The patient underwent laparotomy for tumor resection, but the tumor recurred one month after operation. To our knowledge, the CT appearance of ruptured intraperitoneal MFH complicated by hemoperitoneum has not been previously described.

    Primary mucosal leishmaniasis is a rare infectious disease, particularly in immunocompetent patients. We present a 50-year-old patient with a 6-week history of a painful lesion of the left buccal mucosa that mimicked cancer. The exophytic lesion looked invasive, and we took an incisional biopsy specimen to exclude cancer. The diagnosis of leishmaniasis was unexpected, and the patient was successfully treated with amphotericin B for five weeks. After five months the patient had a visceral recurrence. Chronic exophytic and ulcerated mucosal lesions that do not heal within 3-4 weeks should be regarded as the first signs of oral cancer, but primary oral leishmaniasis can easily mimic it.

    One strategy for assessing efficacy of a liver transplant is to monitor perfusion and oxygenation after transplantation. An implantable optical sensor is being developed to overcome inadequacies of current monitoring approaches. To facilitate sensor design while minimizing animal use, a polydimethylsiloxane (PDMS)-based liver phantom was developed to mimic the optical properties of porcine liver in the 630-1000 nm wavelength range and the anatomical geometry of liver parenchyma. Using soft lithography to construct microfluidic channels in pigmented elastomer enabled the 2D approximation of hexagonal liver lobules with 15mm sinusoidal channels, which will allow perfusion with blood-mimicking fluids to facilitate the development of the liver perfusion and oxygenation monitoring system.

    2015-01-01

    Full Text Available Malignant mesothelioma is an uncommon tumor with strong association with asbestos exposure. Few cases of malignant pleural mesothelioma metastatic to the female breast have been reported. Herein, we presented, for the first time, a case of locally infiltrating malignant pleural mesothelioma forming a mass in the breast of a male as the first pathologically confirmed manifestation of the disease. Breast ultrasound revealed an irregular mass in the right breast which involves the pectoralis muscle. Breast core biopsy revealed a proliferation of neoplastic epithelioid cells mimicking an infiltrating pleomorphic lobular carcinoma. IHC studies showed the cells to be positive for calretinin, CK5/6, WT1, and CK7. The cells were negative for MOC-31, BerEp4, ER, and PR. A final diagnosis of malignant mesothelioma, epithelioid type, was rendered. This case demonstrates the importance of considering a broad differential diagnosis in the setting of atypical presentation with application of a panel of IHC markers.

    Cytomegalovirus (CMV) colitis is uncommon in immunocompetent patients, despite a high seroprevalence rate of CMV in the general population. CMV infection has been described in individuals with compromised immune systems: in AIDS, under corticosteroid and immune modulating treatment, with cancer or haematological malignancies. Its most frequent clinical presentation is a necrotising ulcerative form; pseudotumoural CMV colitis has been described as highly exceptional. We report a case of CMV colitis mimicking rectal carcinoma in an immunocompetent elderly woman. The immunosenescence and protein-energy malnutrition increase incidence and severity of infectious diseases in elderly individuals. Immunosenescence may affect all aspects of immunity; severe protein malnutrition modifies mostly cellular immunity, growing susceptibility to infections. PMID:27166009

Other variables that could affect TI, such as the type and characteristics of traumatic events and personal characteristics have been little or no studied. The present study evaluated the power of these variables to predict TI in a sample of 273 college students who had experienced at least one traumatic event. Of the sample, 7.7% and 13.2% responded with TI according to the two stricter definitions adopted. Most of the variables were significantly associated with TI in univariate analyses. However, in a multiple regression analysis, only certain features of the events (occurrence of physical/sexual abuse, number of different types of events experienced and certain reactions to them (perception of how traumatic were the events, severe fear response were significant predictors of TI. Since these predictors explained only 25% of the variance, the influence of other variables -such as neuroticism, negative affectivity and perceived lack of personal control or resources to cope with traumatic events- should be investigated.

    2010-01-01

    Brain edema leading to an expansion of brain volume has a crucial impact on morbidity and mortal-ity following traumatic brain injury as it increases intracra-nial pressure, impairs cerebral perfusion and oxygenation,and contributes to additional ischemic injuries.Classically,two major types of traumatic brain edema exist: "vasogenic"and "cytotoxic/cellular".However, the cellular and molecu-lar mechanisms contributing to the development/resolution of traumatic brain edema are poorly understood and no ef-fective drugs can be used now.Aquaporin-4 (AQP4) is a water-channel protein expressed strongly in the brain, pre-dominantly in astrocyte foot processes at the borders be-tween the brain parenchyma and major fluid compartments, including cerebrospinal fluid and blood.This distribution suggests that AQP4 controls water fluxes into and out of the brain parenchyma.In cytotoxic edema, AQP4 deletion slows the rate of water entry into brain, whereas in vasogenic edema, AQP4 deletion reduces the rate of water outflow from brain parenchyma.AQP4 has been proposed as a novel drug target in brain edema.These findings sug-gest that modulation of AQP4 expression or function may be beneficial in traumatic brain edema.

    Tissue-mimicking phantoms play a crucial role in medical ultrasound research because they can simulate biological soft tissues. In last years, many types of polymeric tissues have been proposed and characterized from an acoustical and a thermal point of view, but, rarely, a deep discussion about the quality of the measurements, in terms of the uncertainty evaluation, has been reported. In this work, considering the necessity to develop laboratory standards for the measurement of ultrasonic exposure and dose quantities, a detailed description of the experimental apparatuses for the sound speed and the attenuation coefficient measurements is given, focusing the attention on the uncertainty evaluation both of the results and analysis algorithms. In particular, this algorithm reveals a novel empirical relation, fixing a limit to the energy content (therefore limits the number of cycles) of the three parts in which the authors have proposed to divide the acoustical signal. Furthermore, the realisation of multi-components phantoms, Agar and Phytagel based tissue-mimicking gels along with others long chain molecules (dextrane or polyvinyl alcohol) and scattering materials (silicon carbide and kieselguhr) are investigated. This paper reports accurate speed of sound and attenuation coefficient measurements. Speed of sound is measured by a pulse-echo technique in far-field condition, using an optical glass buffer rod; while attenuation coefficient is determined by an insertion technique, using demineralized water as reference material. The experimental sound speed results are subjected to an overall estimated relative uncertainty of about 1.5% and the attenuation coefficient uncertainty is less than 2.5%. For the development of laboratory standards, a detailed analysis of the measurement uncertainty is fundamental to make sample properties comparable. The authors believe this study could represent the right direction to make phantoms characterizations referable and traceable

    Full Text Available A persistência do canal arterial ocorre com freqüência em neonatos prematuros, provocando um grave quadro de disfunção cardiopulmonar. O tratamento envolve duas abordagens, sendo uma clínica e outra cirúrgica. A operação para a ligadura do canal arterial é praticada desde 1938. O enfoque clínico preconiza o uso da indometacina, com o intuito de promover a oclusão do canal arterial. O presente trabalho tem por objetivo avaliar os resultados obtidos com o tratamento cirúrgico da persistência do canal arterial, através de toracotomia e ligadura em 14 pacientes, incluindo crianças de baixo peso e neonatos prematuros com quadro clínico instável. A principal indicação cirúrgica, nestes casos, foi a presença de insuficiência respiratória aguda e insuficiência cardíaca. A técnica empregada foi a tripla ligadura do canal arterial. Nos 14 casos não obtivemos nenhum tipo de complicação e sem mortalidade. A presença de uma Unidade de Tratamento Intensivo Neonatal (U.T.I no Hospital foi de extremo valor no preparo dos pacientes e na evolução no período de pós-operatório. Este trabalho comprova a eficácia do método cirúrgico empregado, com baixas taxas de morbidade e mortalidade e a importância da U.T.I neonatal no acompanhamento dos pacientes.The patent ductus arterious frequently occurs in premature neonates causing serious cardiopulmonary disfunction. The treatment includes two options; one clinic and the other surgical procedure. The surgery for patent ductus arteriosus has been done since 1938. Clinical treatment with indometacin induces closure of the arteriosus ductus. The aim of the article is to analize the surgical results with thoractomy by triple-ligature of the ductus for the treatment of persistent ductus arteriosus in fourteen patients including low weight children and premature neonates with cardiopulmonary disfunction. The indications for surgery in these cases were respiratory distress and congestive

    Full Text Available Purpose: To investigate the incidence, mechanisms, characteristics, and visual outcomes of traumatic wound dehiscence following keratoplasty. Methods: Medical records of 32 consecutive patients with traumatic globe rupture following keratoplasty who had been treated at our center from 2001 to 2009 were retrospectively reviewed. Results: The study population consisted of 32 eyes of 32 patients including 25 men and 7 women with history of corneal transplantation who had sustained eye trauma leading to globe rupture. Mean patient age was 38.1 (range, 8 to 87 years and median interval between keratoplasty and the traumatic event was 9 months (range, 30 days to 20 years. Associated anterior segment findings included iris prolapse in 71.9%, lens extrusion in 34.4%, and hyphema in 40.6% of eyes. Posterior segment complications included vitreous prolapse (56%, vitreous hemorrhage (28% and retinal detachment (18%. Eyes which had undergone deep anterior lamellar keratoplasty (DALK; 5 cases, 15.6% tended to have less severe presentation and better final visual acuity. There was no correlation between the time interval from keratoplasty to the traumatic event, and final visual outcomes. Conclusion: The host-graft interface demonstrates decreased stability long after surgery and the visual prognosis of traumatic wound dehiscence is poor in many cases. An intact Descemet′s membrane in DALK may mitigate the severity of ocular injuries, but even in these cases, the visual outcome of globe rupture is not good and prevention of ocular trauma should be emphasized to all patients undergoing any kind of keratoplasty.

    The aim of this study was to determine the influence of lateral thoracotomy on the development of scoliosis in subjects undergoing repair of coarctation of the aorta (CoA) and patent ductus arteriosus (PDA). A group of 133 patients with CoA and PDA was evaluated. Forty-five patients with CoA and 38 with PDA underwent surgery using standard posterolateral thoracotomy (operative group), whereas 12 patients with CoA and 31 with PDA were treated using balloon dilatation and stent or coil implantation (nonoperative group). A spinal examination, together with the evaluation of chest and spinal roentgenograms, was conducted. Among the operated patients, 62% of those with CoA and 55% of those with PDA had clinical scoliosis. In the nonoperated patients, scoliosis was present in only 25% of those with CoA and 16% of those with PDA. Scoliosis ranged between 10 degrees and 42 degrees . In 89% of the operated patients with CoA and 76% of those with PDA the curve was thoracic; in 46% of the CoA group and 57% of the PDA group the curve was left-sided. All curves were right-sided in nonoperated subjects. Scoliosis in the operated group was higher in male than in female subjects (63% vs. 60% in CoA and 86% vs. 37% in PDA). The prevalence of scoliosis after standard posterolateral thoracotomy was significantly higher than after nonsurgical treatment methods in the CoA and PDA groups as well as in the general population. The rate of single thoracic and the rate of left-sided thoracic curves in patients after thoracotomy is higher than in nonoperated patients or in those with idiopathic scoliosis. The rate of scoliosis after thoracotomy is higher in male than female patients, especially after thoracotomy for PDA. PMID:19597861

    The conventional transcatheter closure of patent ductus arteriosus (PDA) requires femoral artery puncture and angiography for duct anatomic and shunting estimation. If such estimation can be replaced by transthoracic echocardiography (TTE), the procedure will be further simplified, with fewer invasions. This study aimed to examine whether TTE can serve as an alternative to aorta angiography and as a major guidance for transcatheter duct closure. The study enrolled 298 consecutive patients (71 males and 227 females) with PDA. In the study, TTE with combined two-dimensional echocardiography (2DE) imaging and color-coded flow imaging (CDFI) was performed to measure the minimal shunting width (MSW) as the estimated minimal duct size for selection of an Amplatzer duct occluder (ADO) and to monitor the transcatheter duct closure intraprocedurally. The MSW was validated against the duct-stretched diameter (SDD), against the minimal waist diameter of the conical part of a released occluder measured by X-ray spot picture after successful duct closure (SDC), and against the size of the finally used ADO (SADO). Good correlation was found between MSW and SDD [SDD (mm) = 1.31 MSW; r = 0.89; p MSW and SADO [SADO (mm) = 1.71 MSW; r = 0.88; p MSW as the reference for selection of the occluder, SDC was attained in 288 (97.3%), 5 (1.7%), and 2 (0.7%) patients, respectively, at the first, second (1 ADO replacement), and third (2 ADO replacements) occluding attempt. Acute occluder dislodgement occurred in one patient (0.3%). At the 12-month follow-up assessment, no major complications were found, and the total immediate or 12-month SDC was 99.7%. Echocardiography as an alternative major guidance to angiography for transcatheter duct closure is technically feasible, and TTE guidance can further simplify the procedure, with fewer invasions and potential complications.

    The fidelity of cell culture simulations of traumatic brain injury (TBI) that yield tolerance and mechanistic information relies on both the cellular models and mechanical insult parameters. We have designed and characterized an electro-mechanical cell shearing device in order to produce a controlled high strain rate injury (up to 0.50 strain, 30 s(-1) strain rate) that deforms three-dimensional (3-D) neural cultures (neurons or astrocytes in an extracellular matrix scaffold). Theoretical analysis revealed that these parameters generate a heterogeneous 3-D strain field throughout the cultures that is dependent on initial cell orientation within the matrix, resulting in various combinations of normal and shear strain. The ability to create a linear shear strain field over a range of input parameters was verified by tracking fluorescent microbeads in an acellular matrix during maximal displacement for a range of strains and strain rates. In addition, cell death was demonstrated in rat cortical astrocytes and neurons in response to high rate, high magnitude shear strain. Furthermore, cell response within the 3-D neuronal cultures depended on orientation, with higher predicted shear strain correlating with an increased loss of neurites, indicating that culture configuration may be an important factor in the mechanical, and hence cellular, response to traumatic insults. Collectively, these results suggest that differential responses exist within a 3-D culture subjected to mechanical insult, perhaps mimicking the in vivo environment, and that this new model can be used to investigate the complex cellular mechanisms associated with TBI.

    A pilot study was carried out to investigate the performance of ultrasound stiffness imaging methods namely Ultrasound Elastography Imaging (UEI) and Acoustic Radiation Force Impulse (ARFI) Imaging. Specifically their potential for characterizing different classes of solid mass lesions was analyzed using agar based tissue mimicking phantoms. Composite tissue mimicking phantom was prepared with embedded inclusions of varying stiffness from 50 kPa to 450 kPa to represent different stages of cancer. Acoustic properties such as sound speed, attenuation coefficient and acoustic impedance were characterized by pulse echo ultrasound test at 5 MHz frequency and they are ranged from (1564 ± 88 to 1671 ± 124 m/s), (0.6915 ± 0.123 to 0.8268 ± 0.755 db cm(-1)MHz(-1)) and (1.61 × 10(6) ± 0.127 to 1.76 × 10(6) ± 0.045 kg m(-2)s(-1)) respectively. The elastic property Young's Modulus of the prepared samples was measured by conducting quasi static uni axial compression test under a strain rate of 0.5mm/min upto 10 % strain, and the values are from 50 kPa to 450 kPa for a variation of agar concentration from 1.7% to 6.6% by weight. The composite phantoms were imaged by Siemens Acuson S2000 (Siemens, Erlangen, Germany) machine using linear array transducer 9L4 at 8 MHz frequency; strain and displacement images were collected by UEI and ARFI. Shear wave velocity 4.43 ± 0.35 m/s was also measured for high modulus contrast (18 dB) inclusion and X.XX m/s was found for all other inclusions. The images were pre processed and parameters such as Contrast Transfer Efficiency and lateral image profile were computed and reported. The results indicate that both ARFI and UEI represent the abnormalities better than conventional US B mode imaging whereas UEI enhances the underlying modulus contrast into improved strain contrast. The results are corroborated with literature and also with clinical patient images. PMID:24083832

    Background Traumatic events such as disasters, accidents, war, or criminal violence are often accompanied by the loss of loved ones, and may then give rise to traumatic grief. Traumatic grief refers to a clinical diagnosis of persistent complex bereavement disorder (PCBD) with comorbid (symptoms of) posttraumatic stress disorder (PTSD) and/or major depressive disorder (MDD) following confrontation with a traumatic loss. Trauma survivors, who are frequently from different cultural backgrounds, have often experienced multiple losses and ambiguous loss (missing family members or friends). Current evidence-based treatments for PTSD do not focus on traumatic grief. Objective To develop a treatment for traumatic grief combining treatment interventions for PTSD and PCBD that may accommodate cultural aspects of grief. Method To provide a rationale for treatment, we propose a cognitive stress model of traumatic grief. Based on this model and on existing evidence-based treatments for PTSD and complicated grief, we developed Brief Eclectic Psychotherapy for Traumatic Grief (BEP-TG) for the treatment of patients with traumatic grief. The treatment is presented along with a case vignette. Results Processes contributing to traumatic grief include inadequately integrating the memory of the traumatic loss, negative appraisal of the traumatic loss, sensitivity to matching triggers and new stressors, and attempting to avoid distress. BEP-TG targets these processes. The BEP-TG protocol consists of five parts with proven effectiveness in the treatment of PCBD, PTSD, and MDD: information and motivation, grief-focused exposure, memorabilia and writing assignments, finding meaning and activation, and a farewell ritual. Conclusion Tailored to fit the needs of trauma survivors, BEP-TG can be used to address traumatic grief symptoms related to multiple losses and ambiguous loss, as well as cultural aspects of bereavement through its different components.

    The retrospective analysis of the postoperative course in 204 traumatic cataracts (140 isolated, simple cataracts and 64 aggravated ones) showed an apparent functional improvement in the simple cases (preoperative and postoperative visual acuity 0.0139 and 0.8520, respectively); the incidence of postoperative detachment of retina was of 4.9%, that of postoperative endophthalmitis that of cystoid macular edema of 3.2%; complications more commonly occurred in aggravated traumatic cataracts and partially accounted for the poorer functional results. During the investigated interval (1988-1992) a rapid shift to extracapsular cataract extraction and posterior chamber lens implants was made. The crystalline grafts preserved binocular vision in 92% of the cases and contact lens in 50% of the cases. Lens implant remains a matchless solution for the visual rehabilitation of the patients with aphakia. PMID:7654673

    Traumatic brain injury constitutes a significant proportion of cases requiring forensic examination, and it encompasses (1) blunt, nonmissile head injury, especially involving motor vehicle accidents, and (2) penetrating, missile injury produced by a range of high- and lower-velocity projectiles. This review examines the complex pathophysiology and biomechanics of both types of neurotrauma and assesses the macroscopic and histologic features of component lesions, which may be used to determine the cause and manner of death resulting from an intentional assault or accident. Estimation of the survival time postinjury by pathologic examination is also important where malicious head injury is suspected, in an attempt to ascertain a time at which the traumatic event might have been committed, thereby evaluating the authenticity of statements made by the alleged perpetrator.

    Full Text Available Introduction. Traumatic brain injuries have major socio-economic importance due to their frequency, high mortality and serious consequences. According to their nature the consequences of these injuries may be classified as neurological, psychiatric and esthetic. Various lesions of brain structures cause neurological consequences such as disturbance of motor functions, sensibility, coordination or involuntary movements, speech disturbances and other deviations, as well as epilepsy. Psychiatric consequences include cognitive deficit, emotional disturbances and behavior disturbances. Criminal-legal aspect of traumatic brain injuries and litigation. Criminal-legal aspect of traumatic brain injuries expertise understands the qualification of these injuries as mild, serious and qualified serious body injuries as well as the expertise about the mechanisms of their occurrence. Litigation expertise includes the estimation of pain, fear, diminished, i.e. lost vital activity and disability, esthetic marring, and psychological suffer based on the diminished general vital activity and esthetic marring. Competence and timing of expertise. Evaluation of consequences of traumatic brain injuries should be performed only when it can be positively confirmed that they are permanent, i.e. at least one year after the injury. Expertise of these injuries is interdisciplinary. Among clinical doctors the most competent medical expert is the one who is in charge for diagnostics and injury treatment, with the recommendation to avoid, if possible, the doctor who conducted treatment. For the estimation of general vital activity, the neurological consequences, pain and esthetic marring expertise, the most competent doctors are neurosurgeon and neurologist. Psychological psychiatric consequences and fear expertise have to be performed by the psychiatrist. Specialists of forensic medicine contribute with knowledge of criminal low and legal expertise.

    Full text: The possibilities and advantages of US tomography in the diagnosis and follow-up of traumatic hemothorax in major trauma patients were presented. US examinations of the chest in conditions of emergency with purpose to identify hemothorax were performed in 56 (41 male and 15 female patients for a period of two years.US machine 'Siemens-Adara' supplied with 3.5 and 7 MHz linear and convex transducers was used. The right and left intercostal oblique view was used for US examination to identify free pleural fluid. Tube thoracotomy and/or a CT scan of the chest were used as the criterion standard for positive findings of hemothorax among the studied patients. In 49 (87.5%) of all 56 major trauma patients was achieved true-positive diagnostic result of hemothorax confirmed in 39 cases post operatively and in 10 after investigation by CT. In 6 (10.71%) patients - true-negative and in 1 (1.7%) false negative results were obtained. Our experience demonstrated that US is a sensitive, specific, and accurate diagnostic method in detecting traumatic hemothorax. The advantages of US tomography in the diagnosis of traumatic hemothorax are: First - the examination is not influenced by the position of the patient: Second - the rapidity of examination is 2-4 min and simultaneously differentiation of dense regions. Third - the possibility to present small amount of liquid collections 20-30 cc

    Full Text Available Traumatic asphyxia is a condition presenting with cervicofacial cyanosis and edema, subconjunctival hemorrhage, and petechial hemorrhages of the face, neck, and upper chest that occurs due to a compressive force to the thoracoabdominal region.In this case report a 52 years old lady who was brought to the mortuary because of death due to traumatic asphyxia as a result of being stampeded by her own cows upon her chest was discussed. Congestion on both the conjunctiva, cyanosis on chin and adjacent upper left side of neck found with a well demarcated area observed between the cyanosed area over face and the normal area of neck. Hematoma was present in the chin and the adjacent neck region.Apart from quickly eliminating organ pathologies and initiation of supportive therapy in a case of traumatic asphyxia, possibility of formation of hematoma in neck after few hours of getting injured should also be considered, as this type of hematoma may contribute to the cause of death.DOI: http://dx.doi.org/10.3126/jcmsn.v10i3.12777 Journal of College of Medical Sciences-Nepal, 2014, Vol-10, No-3, 51-55

    Full Text Available Traumatic brain injury (TBI is a significant cause of morbidity and mortality in many age groups. Neuroendocrine dysfunction has been recognized as a consequence of TBI and consists of both anterior and posterior pituitary insufficiency; water and electrolyte abnormalities (diabetes insipidus (DI and the syndrome of inappropriate antidiuretic hormone secretion (SIADH are amongst the most challenging sequelae. The acute head trauma can lead (directly or indirectly to dysfunction of the hypothalamic neurons secreting antidiuretic hormone (ADH or of the posterior pituitary gland causing post-traumatic DI (PTDI. PTDI is usually diagnosed in the first days after the trauma presenting with hypotonic polyuria. Frequently, the poor general status of most patients prevents adequate fluid intake to compensate the losses and severe dehydration and hypernatremia occur. Management consists of careful monitoring of fluid balance and hormonal replacement. PTDI is associated with high mortality, particularly when presenting very early following the injury. In many surviving patients, the PTDI is transient, lasting a few days to a few weeks and in a minority of cases, it is permanent requiring management similar to that offered to patients with non-traumatic central DI.

    The adenine and guanine riboswitches regulate gene expression in response to their purine ligand. X-ray structures of the aptamer moiety of these riboswitches are characterized by a compact fold in which the ligand forms a Watson-Crick base pair with residue 65. Phylogenetic analyses revealed a strict restriction at position 39 of the aptamer that prevents the G39-C65 and A39-U65 combinations, and mutational studies indicate that aptamers with these sequence combinations are impaired for ligand binding. In order to investigate the rationale for sequence conservation at residue 39, structural characterization of the U65C mutant from Bacillus subtilis pbuE adenine riboswitch aptamer was undertaken. NMR spectroscopy and X-ray crystallography studies demonstrate that the U65C mutant adopts a compact ligand-free structure, in which G39 occupies the ligand-binding site of purine riboswitch aptamers. These studies present a remarkable example of a mutant RNA aptamer that adopts a native-like fold by means of ligand mimicking and explain why this mutant is impaired for ligand binding. Furthermore, this work provides a specific insight into how the natural sequence has evolved through selection of nucleotide identities that contribute to formation of the ligand-bound state, but ensures that the ligand-free state remains in an active conformation.

    The multiple protecting and barrier-supporting properties of the creamy, white biofilm vernix caseosa (VC) before and after birth suggest that a VC biomimetic could be an innovative barrier cream for barrier-deficient skin. The aim of this study was the rational design and preparation of synthetic biofilms mimicking the unique composition and properties of natural VC. Hexagonal, highly hydrated hyperbranched polyglycerol microgel particles (30 microm in diameter) were embedded in a synthetic lanolin-based lipid mixture using a micromixer. In these formulations, the water content of the particles (i.e. 50% and 80%), an additional lipid coating of the particles and different particle/lipid ratios were varied. Characterization with confocal laser scanning microscopy (CLSM) showed a homogeneous distribution of the labeled particles in the lipid matrix. Regarding structural appearance, particle density and distribution, the formulations with a high particle/lipid ratio (5:1) resembled native VC very closely. Comparable results between native VC and the synthetic formulations were obtained concerning water handling properties, thermotropic behavior while lower elasticity and lower viscosity were observed for the synthetic biofilms. The biofilm formulations were stable for at least 1 month at 4 degrees C. In conclusion, our formulations mimic natural VC very closely and are promising candidates for in vivo studies.

    Full Text Available Relapsing polychondritis (RP is a severe progressive inflammatory condition involving cartilaginous structures and caused by an autoimmune process, for which there is no confirmatory serological biomarker and which still is diagnosed on a mainly clinical basis. RP has been associated with many diseases like Sweet’s syndrome, Behcet’s disease, rheumatoid arthritis, and other autoimmune disorders. We attempt to describe here a unique case of a 38-year-old female with a high-grade fever, sore throat, difficulty in swallowing, hoarseness of the voice, and found to have signs of tongue swelling and inflammation of the oral cavity that mimicked Ludwig’s angina, necessitating antibiotic use. On careful re-evaluation the patient was diagnosed to have relapsing polychondritis based on auricular and respiratory tract chondritis and response to steroids. The purpose of this report is to emphasize the fact that careful clinical assessment is needed to diagnose RP, which may be misdiagnosed as Ludwig’s angina.

    Incorporation of charcoal produced by biomass pyrolysis (biochar) in agricultural soils is a potentially sustainable strategy for climate change mitigation. However, some side effects of large-scale biochar application need to be investigated. In particular a massive use of a low-reflecting material on large cropland areas may impact the climate via changes in surface albedo. Twelve years of MODIS-derived albedo data were analysed for three pairs of selected agricultural sites in central Italy. In each pair bright and dark coloured soil were identified, mimicking the effect of biochar application on the land surface albedo of complex agricultural landscapes. Over this period vegetation canopies never completely masked differences in background soil colour. This soil signal, expressed as an albedo difference, induced a local instantaneous radiative forcing of up to 4.7 W m-2 during periods of high solar irradiance. Biochar mitigation potential might therefore be reduced up to ˜30%. This study proves the importance of accounting for crop phenology and crop management when assessing biochar mitigation potential and provides more insights into the analysis of its environmental feedback.

    Full Text Available Context Majority of the patients developing obstructive jaundice have an underlying malignancy. Identification of a benign pathology like heterotopic pancreas as an aetiology is uncommon and usually occurs only subsequent to a major operation. Case report We report a case of heterotopic pancreas adjacent to the ampulla of Vater mimicking distal cholangiocarcinoma. A 47- year-old patient presented with abdominal pain and obstructive jaundice. ERCP demonstrated a distal common bile duct stricture suspicious of cholangiocarcinoma. He underwent a pylorus-preserving pancreaticoduodenectomy. Histology showed a nodule of heterotopic pancreatic tissue adjacent to the ampulla. Conclusion We have reviewed the literature on heterotopic pancreas of the periampullary region presenting with biliary obstruction. This is a rare entity and remains difficult to diagnose, despite advances in radiological and endoscopic imaging techniques. For symptomatic patients with an established diagnosis of periampullary heterotopic pancreas, local excision may be sufficient. However, in the absence of unequivocal imaging or histological confirmation of benign pathology, and when there is a suspicion of underlying malignancy, pancreaticoduodenectomy may be the only treatment option, as in this case.

  20. Acoustic resolution photoacoustic Doppler velocimetry in blood-mimicking fluids

    Brunker, Joanna; Beard, Paul

    2016-02-01

    Photoacoustic Doppler velocimetry provides a major opportunity to overcome limitations of existing blood flow measuring methods. By enabling measurements with high spatial resolution several millimetres deep in tissue, it could probe microvascular blood flow abnormalities characteristic of many different diseases. Although previous work has demonstrated feasibility in solid phantoms, measurements in blood have proved significantly more challenging. This difficulty is commonly attributed to the requirement that the absorber spatial distribution is heterogeneous relative to the minimum detectable acoustic wavelength. By undertaking a rigorous study using blood-mimicking fluid suspensions of 3 μm absorbing microspheres, it was discovered that the perceived heterogeneity is not only limited by the intrinsic detector bandwidth; in addition, bandlimiting due to spatial averaging within the detector field-of-view also reduces perceived heterogeneity and compromises velocity measurement accuracy. These detrimental effects were found to be mitigated by high-pass filtering to select photoacoustic signal components associated with high heterogeneity. Measurement under-reading due to limited light penetration into the flow vessel was also observed. Accurate average velocity measurements were recovered using “range-gating”, which furthermore maps the cross-sectional velocity profile. These insights may help pave the way to deep-tissue non-invasive mapping of microvascular blood flow using photoacoustic methods.

    Full Text Available Background. Ultrasound (US is the most accurate tool in the diagnosis of thyroid nodules if performed by expert physician. Misdiagnosis due to extrathyroidal lesions mimicking thyroid nodules is reported in literature. We describe the first case of an esophageal fibrovascular polyp misdiagnosed as a thyroid nodule on US examination. Patient Findings. A 54-year-old woman presented to emergency department for headache and underwent carotid Doppler extended to neck ultrasound with incidental finding of a nodule in the posterior side of the left thyroid lobe. A following thyroid US performed by an endocrinologist allowed the characterization of the lesion as an esophageal pathology, considering the extrathyroidal position, the typical peripheral hyperechoic spots and hypoechoic rim, the connection to the esophagus, and the swallowing connected movement. The patient was addressed to further investigations and finally to anterior pharyngotomy with histological diagnosis of esophageal fibrovascular polyp. Summary. Differential diagnosis between thyroid nodules and other neck lesions is important to prevent an unnecessary fine needle aspiration biopsy and to treat the extrathyroidal pathology. In this case, an US performed by an expert endocrinologist allowed detecting an esophageal fibrovascular polyp requiring surgical removal. In conclusion, the possibility of an esophageal pathology, and even fibrovascular polyp, should be considered during US thyroid examination.

    Full Text Available Abstract Introduction The incidence of tuberculosis is rising worldwide and rare manifestations of the past are seen more often nowadays. Mammary tuberculosis is a rare clinical entity, often mimicking breast cancer or abscesses of benign or malignant origin. Clinical awareness is necessary during diagnostic work-up for establishing the correct diagnosis and treatment. Case presentation We present a case of breast tuberculosis diagnosed in a 73 year old woman at our institution. The patient presented with a palpable mass of the right breast with clinical, laboratory and mammographic findings indicative of breast carcinoma. The patient underwent lumpectomy and sentinel lymph node biopsy. Frozen section of the tumor and the sentinel node revealed "granulomatous inflammation", while gross examination confirmed the diagnosis of tuberculous mastitis. The patient received anti-tuberculosis therapy for six months with no side effects or any further complications. Conclusion Breast tuberculosis is an obscure disease often mistaken for carcinoma or pyogenic abscess of the breast, especially if well-defined clinical features are absent. A high index of suspicion is required because the disease can usually be treated conservatively with current antituberculous modalities while surgical intervention is reserved for rare cases only.

    We present a case of a seven-year-old immunocompetent female patient who developed systemic symptoms mimicking an autoimmune rather than an infectious disease. The patient presented with rash, biquotidian fever, night sweats, and arthralgias. There was no antecedent history of cat contact. Investigations showed increased inflammatory markers, leukocytosis, thrombocytosis, hypercalcemia, and raised angiotensin-converting enzyme. Interferon-gamma releasing assay for tuberculosis infection was negative. Abdominal imaging demonstrated multifocal lesions of the liver and spleen (later proved to be granulomata), chest X-ray showed enlarged hilar lymph nodes, and ophthalmology review revealed uveitis. Clinical, laboratory, and imaging features pointed towards sarcoidosis. Subsequently, raised titers (IgM 1 : 32, IgG 1 : 256) against Bartonella confirmed the diagnosis of B. henselae infection. She was treated with gentamycin followed by ciprofloxacin; repeat investigations showed complete resolution of findings. The presence of hepatic and splenic lesions in children with bartonellosis is well documented. Our case, however, exhibited certain unusual findings such as the coexistence of acute ocular and systemic involvement in an immunocompetent host. Serological testing is an inexpensive and effective way to diagnose bartonellosis in immunocompetent patients; we suggest that bartonella serology is included in the baseline tests performed on children with prolonged fever even in the absence of contact with cats in countries where bartonellosis is prevalent.

    Cumulative tool-based culture underwrote our species' evolutionary success, and tool-based nut-cracking is one of the strongest candidates for cultural transmission in our closest relatives, chimpanzees. However the social learning processes that may explain both the similarities and differences between the species remain unclear. A previous study of nut-cracking by initially naïve chimpanzees suggested that a learning chimpanzee holding no hammer nevertheless replicated hammering actions it witnessed. This observation has potentially important implications for the nature of the social learning processes and underlying motor coding involved. In the present study, model and observer actions were quantified frame-by-frame and analysed with stringent statistical methods, demonstrating synchrony between the observer's and model's movements, cross-correlation of these movements above chance level and a unidirectional transmission process from model to observer. These results provide the first quantitative evidence for motor mimicking underlain by motor coding in apes, with implications for mirror neuron function. PMID:24923651

  15. Measurement of guided mode wavenumbers in soft tissue–bone mimicking phantoms using ultrasonic axial transmission

    International Nuclear Information System (INIS)

    Human soft tissue is an important factor that influences the assessment of human long bones using quantitative ultrasound techniques. To investigate such influence, a series of soft tissue–bone phantoms (a bone-mimicking plate coated with a layer of water, glycerol or silicon rubber) were ultrasonically investigated using a probe with multi-emitter and multi-receiver arrays in an axial transmission configuration. A singular value decomposition signal processing technique was applied to extract the frequency-dependent wavenumbers of several guided modes. The results indicate that the presence of a soft tissue-mimicking layer introduces additional guided modes predicted by a fluid waveguide model. The modes propagating in the bone-mimicking plate covered by the soft-tissue phantom are only slightly modified compared to their counterparts in the free bone-mimicking plate, and they are still predicted by an elastic transverse isotropic two-dimensional waveguide. Altogether these observations suggest that the soft tissue–bone phantoms can be modeled as two independent waveguides. Even in the presence of the overlying soft tissue-mimicking layer, the modes propagating in the bone-mimicking plate can still be extracted and identified. These results suggest that our approach can be applied for the purpose of the characterization of the material and structural properties of cortical bone. (paper)

    Pseudoknots are a fundamental RNA tertiary structure with important roles in regulation of mRNA translation. Molecular force spectroscopic approaches such as optical tweezers can track the pseudoknot's unfolding intermediate states by pulling the RNA chain from both ends, but the kinetic unfolding pathway induced by this method may be different from that in vivo, which occurs during translation and proceeds from the 5' to 3' end. Here we developed a ribosome-mimicking, nanopore pulling assay for dissecting the vectorial unfolding mechanism of pseudoknots. The pseudoknot unfolding pathway in the nanopore, either from the 5' to 3' end or in the reverse direction, can be controlled by a DNA leader that is attached to the pseudoknot at the 5' or 3' ends. The different nanopore conductance between DNA and RNA translocation serves as a marker for the position and structure of the unfolding RNA in the pore. With this design, we provided evidence that the pseudoknot unfolding is a two-step, multistate, metal ion-regulated process depending on the pulling direction. Most notably, unfolding in both directions is rate-limited by the unzipping of the first helix domain (first step), which is Helix-1 in the 5' → 3' direction and Helix-2 in the 3' → 5' direction, suggesting that the initial unfolding step in either pulling direction needs to overcome an energy barrier contributed by the noncanonical triplex base-pairs and coaxial stacking interactions for the tertiary structure stabilization. These findings provide new insights into RNA vectorial unfolding mechanisms, which play an important role in biological functions including frameshifting. PMID:26595106

  20. Pleomorphic adenoma mimicking lymphoma of the palatine tonsil

    International Nuclear Information System (INIS)

    Full text: Introduction: Pleomorphic adenoma is a mixed benign tumor of the salivary glands having myoepithelial and epithelial components. It is frequently encountered in big salivary glands such as parotid glands. Those originating from small salivary glands are usually seen in the palatal region. They can be rarely seen in buccal region, tongue, base of the oral cavity, tonsils, pharynx, retromolar region and nasal cavity. Objectives and tasks: In this article, we aimed to represent computed tomography (CT) and Magnetic resonance imaging findings of a case with pleomorphic adenoma located in the palatine tonsil region mimicking lymphoma. Material and methods: 19-year-old boy was referred to our radiology clinic due asymmetrical hypertrophic changes in the left palatine tonsil region. The case was evaluated by contrast enhanced CT and MR. Results: In CT, a 2.5x3 cm hypodense solid lesion without prominent contrast enhancement located in the left palatine tonsil region narrowing the nasopharyngeal-oropharyngeal passage was revealed. In MR imaging lesion was isointense to the muscle tissue in T1WI and hyperintense in T2WI. It was showing heterogeneous contrast enhancement in postcontrast T1WI. As a consequence, palatine tonsil lymphoma was compatible with radiologic features. But, diagnosis was turned out to be pleomorphic adenoma by histopathologic assessment. Conclusion: Salivary gland neoplasia is rarely seen in the minor salivary glands. The diagnosis of atypically located salivary gland tumor may be challenging. CT and MR imaging can be used to assess the location, dimensions, extension and relationship with the adjacent structures of the tumor. The minor salivary gland tumor such as pleomorphic adenoma should be included in the differential diagnoses in lesion located in the oral-nasal-pharyngeal regions

We retrospectively studied atypical lymphocytes (AL and atypical lymphocytosis (ALO, defined as AL > 5% of total white blood cells in 1310 uncomplicated malaria patients. In 718 falciparum malaria patients, AL and ALO on day 0 were found in 53.2% and 5.7% of the patients, respectively, with median AL on admission of 1% (range 0%–10%, whereas in 592 vivax malaria patients, AL and ALO on day 0 were found in 55.4% and 9.5% of the patients, respectively, with median AL on admission of 1% (range 0%–14%. After antimalarial treatment, AL and ALO declined in both falciparum and vivax malaria. However, AL and ALO remained in falciparum malaria on days 7, 14, and 21, whereas AL and ALO remained in vivax malaria on days 7, 14, 21, and 28. In both falciparum and vivax malaria patients, there was a positive correlation between AL and total lymphocytes, but a negative correlation between AL and highest fever on admission, white blood cells, and neutrophils, eosinophils, and platelets (P < 0.05. In conclusion, AL or ALO may be found in uncomplicated falciparum and vivax malaria mimicking dengue infection. In tropical countries where both dengue and malaria are endemic, presence of AL or ALO in any acute febrile patients with thrombocytopenia (similar to the findings in dengue malaria could not be excluded. Particularly if the patients have risk of malaria infection, confirmative microscopic examination for malaria should be carried out

    2007-01-01

    Full Text Available Abstract Background Hypophosphatasia (HP is characterized by a genetic defect in the tissue-nonspecific alkaline phosphatase (TNSALP gene and predominantly an autosomal recessive trait. HP patients suffer from reduced bone mineralization. Biochemically, elevated concentrations of substrates of TNSALP, including pyridoxal-5'-phosphate and inorganic pyrophosphate occur in serum, tissues and urine. The latter has been associated with chronic inflammation and hyperprostaglandinism. Case presentation We report on 2 affected children presenting with multifocal inflammatory bone lesions mimicking malignancy: A 6 years old girl with short stature had been treated with human growth hormone since 6 months. Then she started to complain about a painful swelling of her left cheek. MRI suggested a malignant bone lesion. Bone biopsy, however, revealed chronic inflammation. A bone scan showed a second rib lesion. Since biopsy was sterile, the descriptive diagnosis of chronic non-bacterial osteomyelitis (CNO was established. The diagnostic tests related to growth failure were repeated and subsequent analyses demonstrated a molecular defect in the TNSALP gene. The second girl (10 years old complained about back pain after she had fallen from her bike. X rays of her spine revealed compressions of 2 thoracic vertebrae. At first these were considered trauma related, however a bone scan did show an additional lesion in the right 4th rib. A biopsy of this rib revealed a sterile lympho- plasmocytoid osteomyelitis suggesting multifocal CNO. Further analyses did show a decreased TNSALP in leukocytes and elevated pyridoxal phosphate in plasma, suggesting a heterozygous carrier status of HP. Conclusion Chronic bone oedema in adult HP and chronic hyper-prostaglandinism in childhood HP do suggest that in some HP patients bone inflammation is present in conjunction with the metabolic defect. Sterile multifocal osteomyelitis could be demonstrated. Non-steroidal anti

  3. Mimicking Nonequilibrium Steady States with Time-Periodic Driving

    Under static conditions, a system satisfying detailed balance generically relaxes to an equilibrium state in which there are no currents. To generate persistent currents, either detailed balance must be broken or the system must be driven in a time-dependent manner. A stationary system that violates detailed balance evolves to a nonequilibrium steady state (NESS) characterized by fixed currents. Conversely, a system that satisfies instantaneous detailed balance but is driven by the time-periodic variation of external parameters—also known as a stochastic pump (SP)—reaches a periodic state with nonvanishing currents. In both cases, these currents are maintained at the cost of entropy production. Are these two paradigmatic scenarios effectively equivalent? For discrete-state systems, we establish a mapping between nonequilibrium stationary states and stochastic pumps. Given a NESS characterized by a particular set of stationary probabilities, currents, and entropy production rates, we show how to construct a SP with exactly the same (time-averaged) values. The mapping works in the opposite direction as well. These results establish a proof of principle: They show that stochastic pumps are able to mimic the behavior of nonequilibrium steady states, and vice versa, within the theoretical framework of discrete-state stochastic thermodynamics. Nonequilibrium steady states and stochastic pumps are often used to model, respectively, biomolecular motors driven by chemical reactions and artificial molecular machines steered by the variation of external, macroscopic parameters. Our results loosely suggest that anything a biomolecular machine can do, an artificial molecular machine can do equally well. We illustrate this principle by showing that kinetic proofreading, a NESS mechanism that explains the low error rates in biochemical reactions, can be effectively mimicked by a constrained periodic driving.

    Full Text Available Background: Management of patients with the brugada ECG sign who have no previous history of syncope is still negotiable. We present a case of a 57 year-old Caucasian lady who presented to the emergency department with substernal chest pain. Results: Her past medical history showed that she had two previous episodes of lightheadedness, but no syncope. She had a family history of sudden death secondary to unknown cause in her aunt at the age of 61. Physical exam was unremarkable except for diaphoresis. Electrocardiography (ECG showed ST elevation in the right precordial leads (V1-V2 with T inversion, mimicking a STEMI. Emergent cardiac catheterization revealed normal coronary arteries. Echocardiogram was normal. Again, interpretation of ECG revealed a Brugada type 1 pattern, characterized by coved-type, gradually descending ST-T segment, elevated J point of more than 2 mm and T wave inversion. Electrophysiological (EPS testing with a Sodium channel blocker challenge showed a persistent Brugada type 1 pattern with non inducible ventricular tachycardia. This patient had Brugada type 1 ECG pattern with no previous history of syncope (asymptomatic. Thus she was considered at low risk of developing a serious arrhythmogenic event in the future. Conclusion: A history of syncope remains the best available predictor for arrhythmogenic events. EPS testing in such patients, to stratify the risk and predict for any future events, is still controversial. It is still unjustified to place an implantable cardioverter-defibrillator in asymptomatic non-inducible individuals with the Brugada pattern. These patients should follow up closely with a cardiologist and be aware of the risk of possible triggers of ventricular arrhythmias.

    2014-09-01

    Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking.

    2015-09-01

    Full Text Available Repetitive brain trauma is associated with a progressive neurological deterioration, now termed as chronic traumatic encephalopathy (CTE. Although research on the long-term effects of TBI is advancing quickly, the incidence and prevalence of post-traumatic neurodegeneration and CTE are unknown. The incidence and prevalence of chronic traumatic encephalopathy and the genetic risk factors critical to its development are currently under research. CTE can be diagnosed only by post mortem neuropathological examination of the brain. Great efforts are being made to better understand the clinical signs and symptoms of CTE, obtained in most cases retrospectively from families of affected persons.Patients with CTE are described as having behavioral, mood, cognitive and motor impairments, occurring after a long latency from the traumatic events. Recent pathogenetic studies have provided new insights to CTE mechanisms, offering important clues in understanding neurodegenerative process and relations between physical factors and pathologic protein deposition. Further research is needed to better identify the genetic and environmental risk factors for CTE, as well as rehabilitation and treatment strategies.

    The primary aim for this research was to explore the overlap and differences between the concepts related to secondary traumatization: posttraumatic stress disorder (PTSD), secondary traumatic stress (STS), compassion fatigue (CF), and burnout (BRN). A secondary aim for this research was to examine the impact of secondary traumatization and some of the personal and professional elements that affect how pediatric healthcare providers experience PTSD, STS, CF, and BRN. An online survey was sent via e-mail to numerous list serves for healthcare providers who had worked on PICU, NICU, or PEDS units within the last year. The analyses revealed that a significant overlap existed between the terms of STS, PTSD, BRN, CS, and CF for PICU, NICU, and PEDS providers. However, a hierarchical linear regression revealed a significant amount of unique contributions to the variance in CF based on each of the measured concepts. Despite previous literature that indicates that the terms STS and CF can be used interchangeably, the two most prominent measures utilized in the assessment of CF and STS are actually capturing at least some unique elements. Given these results, future researchers should examine and conceptualize the difference in etiology, prevalence, symptoms, and treatment efficacy for CF and STS as separate but related entities and then return their focus to understanding secondary traumatization in healthcare providers.

    Full Text Available Abstract Background The aim of the study was to explore resilience among refugee children whose parents had been traumatized and were suffering from Post-Traumatic Stress Disorder (PTSD. Methods The study comprised 80 refugee children (40 boys and 40 girls, age range 6–17 yrs, divided into two groups. The test group consisted of 40 refugee children whose parents had been tortured in Iraq before coming to Sweden. In accordance with DSM-IV criteria, these children were further divided in two sub-groups, those who were assessed as having PTSD-related symptoms (n = 31 and those who did not have PTSD-related symptoms (n = 9. The comparison group consisted of 40 children from Egypt, Syria and Morocco whose parents had not been tortured. Wechsler Intelligence Scale for Children, 3rd edn. (WISC-III, Diagnostic Interview for Children and Adolescents- Revised (DICA-R, Post-Traumatic Stress Symptoms checklist (PTSS, "I Think I am" (ITIA and Strengths and Difficulties Questionnaire (SDQ were used to assess IQ; PTSD-related symptoms; self-esteem; possible resilience and vulnerability. Results Children without PTSD/PTSS in the traumatized parents group had more favorable values (ITIA and SDQ with respect to total scores, emotionality, relation to family, peer relations and prosocial behavior than the children in the same group with PTSD/PTSS and these values were similar to those the children in the comparison group (the non-traumatized parents group. The children in the non-traumatized parents group scored significantly higher on the IQ test than the children with traumatized parents, both the children with PTSD-related symptoms and those without PTSD-related symptoms. Conclusion Adequate emotional expression, supportive family relations, good peer relations, and prosociality constituted the main indicators of resilience. Further investigation is needed to explore the possible effects of these factors and the effects of IQ. The findings of this study are

    Association of repetitive brain trauma with progressive neurological deterioration has been described since the 1920s. Punch drunk syndrome and dementia pugilistica (DP) were introduced first to explain symptoms in boxers, and more recently, chronic traumatic encephalopathy (CTE) has been used to describe a neurodegenerative disease in athletes and military personal with a history of multiple concussions. Although there are many similarities between DP and CTE, a number of key differences are apparent especially when comparing movement impairments. The aim of this review is to compare clinical and pathological aspects of DP and CTE with a focus on disorders of movement. PMID:27021775

    Only a few studies have been reported on the MR contrast enhancement and the apparent diffusion coefficient (ADC) findings of the post-traumatic lesion of the brain. We report a case of the venous ischemia in the left frontal lobe observed in the MRI obtained one day after the incidence of trauma. Considering the presented slight increase in the ADC, the vasogenic edema was thought to be the major mechanism of the venous ischemia and excitotoxic injury. In spite of a slight increase in the ADC, the hyperintensity in the diffusion weighted imaging and contrast-enhanced areas eventually changed into hemorrhagic lesions.

  3. Traumatic ureteropelvic disruption in the child

    International Nuclear Information System (INIS)

    Traumatic disruption of the ureter from the renal pelvis is a rare injury because the ureteropelvic junction is situated deep in the retroperitoneum and is thus protected by the spine and paraspinal muscles. The mechanism for this injury is thought to be the stretching of the proximal ureter by sudden extreme hyperextension of the trunk. As a non-fatal injury, this occurs only in the child because of the greater elasticity and mobility of the young skeleton. At The Children's Hospital we have seen 3 cases of avulsion of the ureter from the pelvis following blunt trauma. (orig.)

    First responders routinely experience work-related events that meet the definition of a traumatic stressor. Despite the high exposure to traumatic events, prevalence rates of posttraumatic stress disorder (PTSD) are relatively low. This discrepancy points to the potential value of identifying factors that distinguish those traumatic stressors that produce ongoing traumatic stress symptoms from those that do not. The present study surveyed 181 first responders from rural settings. A repeated-measures design was used to compare characteristics of traumatic stressors that were or were not associated with ongoing PTSD symptoms. A factor analysis revealed that distressing events were characterized by chaos and resource limitations. Consistent with contemporary models, two mediational analyses revealed that each event characteristic predicted peritraumatic dissociation and posttraumatic cognitions, which in turn predicted PTSD symptoms. Moreover, the effect of each event characteristic on PTSD symptoms was partially mediated by these cognitive processes. PMID:26188614

    Full Text Available Introduction: Sarcoidosis is an inflammatory disease characterized by non-caseating granulomas that can be present in diverse organ systems. Sarcoidosis can be associated with malignancy, presenting either preceding, during, or after chemotherapy. We herewith report a case of sarcoidosis mimicking cancer recurrence that developed after radioactive iodine therapy for papillary thyroid cancer. Background: A 68-year-old Caucasian woman was found to have an incidental mediastinal lymph node. She underwent biopsy, which revealed sarcoidosis. There was no further treatment or evidence of recurrence over the ensuing 9 years. She was then diagnosed with low-grade papillary thyroid cancer in the right posterior lobe and treated with total thyroidectomy followed by radioactive iodine therapy. Six months later, she was found to have elevated serum thyroglobulin. Post–remnant ablation scan showed increased tracer uptake in the bed of the thyroid. Though two thyroid ultrasound scans were negative, she was treated with I-131 for possible recurrence. She then developed right hip pain, prompting further investigation. Though a skeletal survey was negative, an 18-fluorodeoxyglucose positron emission tomography (PET scan study revealed multiple hypermetabolic skeletal lesions in both humeri and the proximal left femur. In addition, hypermetabolic hilar and mediastinal nodes were noted. As widespread cancer metastasis was suspected, bone biopsy was performed, which showed non-caseating granulomas, consistent with recurrence of sarcoidosis. Conclusion: Sarcoid lesions may mimic metastatic disease or recurrence in oncologic patients. Biopsy and histopathology examination should be performed to confirm the diagnosis. Recurrence or reactivation of sarcoidosis has been proposed to result from altered immunologic milieu because of the presence of either active cancer or its therapy. Teodorovic and colleagues postulated that the radioactive I-131 therapy leads to

    Full Text Available The traumatisms that affect the extremities represent 80% of all the vascular traumatisms approximately. The inadequate handling of these it contributes to fateful consequences as the loss of the life or of the function of the extremity. The vascular lesions for firearm constitute one of the main causes with the appearance of arteriovenous fistula. We present the case of a 36 year old masculine patient with antecedents of having hurt 1 year ago by firearm in the root of the left thigh goes to present increase of volume of the extremity and difficulty to the march with sensation of fatigue and gravity. To the physical exam increase of volume of the limb more marked affection was verified in the root of the thigh, in the area related with the bullet impact thrill is felt and blow holosistólico is auscultated. The echo doppler and the tomography with contrast use evidenced the presence of a arteriovenous fistula. With this diagnosis was carried out surgical exploration and repair by means of veins bond for exclusion and interference of ilio-femoral arterial implant of politetrafluoroethylene (PTFE. The postoperative evolution was satisfactory with regression of all the clinical signs.

    Full Text Available The paper present the results of the survey that was designed to examine attitudes towards reconciliation, traumatic experience, as well as some basic values, attitudes and stereotypes in two cities of the former Yugoslavia where the nationalities that were in conflict live together. The survey was conducted on 400 subjects in Vukovar (inhabited by Serbs and Croats and 400 subjects in Prijedor (Serbs and Bosniaks. The results show that the level of traumatic experience, as a single variable, has no correlation with the readiness for reconciliation. On the other hand, in General Linear Model, best predictors of the readiness for reconciliation were attitudes and values represented by the factors “Non-Ethnocentric” and Non-Nationalistic/ Xenophobic”. Also, having friends among the “opposing” nationality and having positive experiences with the members of opposing national groups is highly related to a readiness for reconciliation. Finally, a belief in war crime trials, combined with a readiness to admit the war crimes among its own nationality, was a significant predictor of readiness for reconciliation.

    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.

  17. MRI findings of traumatic cervical disc herniation

    International Nuclear Information System (INIS)

    In general practice, disc hernia is increasingly being questioned about its relation with traffic injuries. In this study, we examined the image findings of cervical disc herniation for findings indicative of traumatic hernia. In 2008, we examined 35 cases of cervical disc herniation at our hospital by MRI. The patients were divided into two groups; patients with trauma history (19 cases) and those without (16 cases), and their images were compared. Disc herniation in the trauma group showed high intensity at T2, with some of the patients in this group also indicating continuous high intensity of the internal and herniated discs. Traumatic force was found to cause swelling under the laryngeal soft tissue. Cases with further flexion injury showed interspinous ligament hemorrhage. These findings strongly suggest the involvement of injury. But given that some younger patients in the non-trauma group also show high intensity at T2*, attention must be paid not to confuse swelling below the larynx with inflammation of the longus colli muscle.

    Traumatic brain injury (TBI) is common and especially with military service. In Iraq and Afghanistan, explosive blast related TBI has become prominent and is mainly from improvised explosive devices (IED). Civilian standard of care clinical practice guidelines (CPG) were appropriate has been applied to the combat setting. When such CPGs do not exist or are not applicable, new practice standards for the military are created, as for TBI. Thus, CPGs for prehospital care of combat TBI CPG [1] and mild TBI/concussion [2] were introduced as was a DoD system-wide clinical care program, the first large scale system wide effort to address all severities of TBI in a comprehensive organized way. As TBI remains incompletely understood, substantial research is underway. For the DoD, leading this effort are The Defense and Veterans Brain Injury Center, National Intrepid Center of Excellence and the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury. This program is a beginning, a work in progress ready to leverage advances made scientifically and always with the intent of providing the best care to its military beneficiaries.

  19. Post traumatic tetanus and role magnesium sulphate

    International Nuclear Information System (INIS)

    Tetanus is a life threatening disease. Reported mortality for tetanus is 15-39%. Conventional treatment includes heavy sedation and artificial ventilation. Complications resulting from long term heavy sedation and artificial ventilation contribute to 60% of the total mortality caused by tetanus. In this study magnesium sulphate was used to reduce the need for sedation and artificial ventilation. Objectives of this prospective study were to determine the role of magnesium sulphate in post traumatic tetanus. The study was carried out in surgical Intensive Care at Pakistan Institute of Medical Sciences (PIMS), Islamabad from Jan 2004 to Dec 2007. Forty-four patients presented during this period and 33 patients were included in the study. All patients had tracheostomy done within 48 hours. Every patient was started Magnesium Sulphate therapy for control of spasms after sending baseline investigations. Patients were given ventilatory support when needed. All data was entered in well structured proforma. SPSS-10 was used to analyse data. Thirty-three patients were included in the study and all patients were given magnesium sulphate. Out of these, 45.5% cases were grade 4 tetanus, 73.6% and 63.3% cases did not require artificial ventilation and additional sedation respectively, 51.1% patients remained free of complications of tetanus. Overall mortality was 30.3%. Use of Magnesium Sulphate is safe and reduces the need for sedation and artificial ventilation in high grade tetanus thus contributing to survival benefit in adult post-traumatic tetanus cases.

    Traumatic musculoskeletal injury results in a high incidence of chronic pain; however, there is little evidence about the nature, quality, and severity of the pain. This study uses a prospective, observational, longitudinal design to (1) examine neuropathic pain symptoms, pain severity, pain interference, and pain management at hospital admission and 4 months after traumatic musculoskeletal injury (n = 205), and (2) to identify predictors of group membership for patients with differing moderate-to-severe putative neuropathic pain trajectories. Data were collected on mechanism of injury, injury severity, pain (intensity, interference, neuropathic quality), anxiety (anxiety sensitivity, general anxiety, pain catastrophizing, pain anxiety), depression, and posttraumatic stress while patients were in-hospital and 4 months after injury. A third of patients had chronic moderate-to-severe neuropathic pain 4 months after injury. Specifically, 11% of patients developed moderate-to-severe pain by 4 months and 21% had symptoms immediately after injury that persisted over time. Significant predictors of the development and maintenance of moderate-to-severe neuropathic pain included high levels of general anxiety while in-hospital immediately after injury (P stress 4 months after injury (P management in-hospital and at 4 months. Future research is needed among trauma patients to better understand the development of chronic pain and to determine the best treatment approaches. PMID:27058677

    Head injury has been the leading cause of death and disability in people younger than 40 years and the incidence is rising continuously. Anticipation of the pathological consequences of post-traumatic subarachnoid hemorrhage (tSAH) and an outcome-oriented management are very important in these cases. To encounter the complications pertaining to traumatic brain injury (TBI) and tSAH, various classifications have been proposed and goal-oriented screening strategies have been offered. The role of serial computed tomography (CT) scans, perfusion studies, transcranial Doppler, magnetic resonance imaging (MRI), and angiographic studies as diagnostic tools, has been described. Recently, MRI fluid-attenuated inversion recovery (FLAIR), gradient reversal echo (GRE), and susceptibility weighted imaging (SWI) have emerged as excellent complimentary MRI sequences, and the authors of this article have evaluated their role in the diagnosis and prognostication of patients with tSAH. Numerous studies have been conducted on the various complications associated with tSAH such as vasospasm, hydrocephalus, and electrolyte disturbances and their management. This article discusses these aspects of tSAH and their management nuances. PMID:26954974

    International Nuclear Information System (INIS)

    We describe a case of epithelioid sarcoma of the median nerve in a 57-year-old woman presenting with symptoms and signs of carpal tunnel syndrome for 2 years. The clinical examination was suggestive of a wrist ganglion compressing the median nerve. Magnetic resonance imaging (MRI) showed a 5 cm x 3 cm mass involving the median nerve in the carpal tunnel and appearances mimicked a benign peripheral nerve sheath tumour. This report illustrates a rare tumour presenting in a rare location and emphasizes the atypical clinical and MRI features that should alert the radiologist to the possibility of a rare sarcoma mimicking a benign peripheral nerve sheath tumour

    The present study aims to examine the relationship between trait resilience and virtues in the context of trauma. A total of 537 participants who attended the preliminary investigation and completed the Life Events Checklist were screened. Of these participants, 142 suffered from personal traumatic experiences in the past year; these individuals were qualified and invited to respond to online questionnaires to assess trait resilience, virtues (i.e., Conscientiousness, Vitality, and Relationship), post-traumatic stress disorder (PTSD) symptoms, and post-traumatic growth (PTG). The following questionnaires were used: Connor-Davidson Resilience Scale-Revised, Chinese Virtues Questionnaire, PTSD Checklist-Specific, and Post-traumatic Growth Inventory-Chinese. Only 95 participants who manifested self-reported PTSD symptoms and PTG were involved in the current analyses. Trauma was positively and significantly correlated with PTSD in the current sample. Results indicated that trait resilience was positively associated with virtues and PTG; by contrast, PTSD scores were negatively but not significantly related to most of these factors. The three virtues contributed to PTG to a greater extent than trait resilience in non-PTSD and PTSD groups. However, trait resilience remained a significant predictor in the PTSD group even when the three virtues were controlled. The relationship between trait resilience and PTG was moderated by PTSD type (non-PTSD group vs. PTSD group). Our results further suggested that trait resilience and virtues were conceptually related but functionally different constructs. Trait resilience and virtues are positively related; thus, these factors contributed variances to PTG in the context of trauma; however, trait resilience is only manifested when virtues are controlled and when individuals are diagnosed as PTSD. Furthermore, implications and limitations of this study are discussed. PMID:25932954

    Highlights: • MR neurography is the imaging modality of choice in patients who have sustained brachial plexus injury. It is helpful in determining the level and extent of injury. • The authors have used a Visual Per-operative Scoring system to assess the usefulness of MR neurography in delineating the level and type of the lesion. • The imaging findings were classified based on the level of injury—root, trunk or cord. These findings were correlated with those seen on surgical exploration. A good correlation was found in the majority (65%) of patients and average correlation (30%) in others. - Abstract: Objectives: Imaging of the brachial plexus has come a long way and has progressed from plain radiography to CT and CT myelography to MRI. Evolution of MR imaging sequences has enabled good visualization of the small components of the plexus. The purpose of our study was to correlate the results of MR neurography (MRN) in patients with traumatic brachial plexopathy with their operative findings. We wanted to determine the usefulness of MRN and how it influenced surgical planning and outcome. Methods: Twenty patients with features of traumatic brachial plexopathy who were referred to the MRI section of the Department of Radiology between September 2012 and January 2014 and subsequently underwent exploration were included in the study. MR neurography and operative findings were recorded at three levels of the brachial plexus—roots, trunks and cords. Results: Findings at the level of roots and trunks were noted in 14 patients each and at the level of the cords in 16 patients. 10 patients had involvement at all levels. Axillary nerve involvement as a solitary finding was noted in two patients. These patients were subsequently operated and their studies were assigned a score based on the feedback from the operating surgeons. The MRN study was scored as three (good), two (average) or one (poor) depending on whether the MR findings correlated with operative

    International Nuclear Information System (INIS)

    This prospective, randomised study was performed to determine the best treatment for mild noncomplicated traumatic hyphema. This study comprised 120 patients who fulfill the criteria of our study. The patient were admitted in our center through the eye casualty department and they were randomly divided into three equal and similar groups, one group received Predforte eye drops, the other received Predforte and Cyclogel 1% eye drops and the control group received Tears Natural eye drops. For each patient, the following characteristics were recorded at presentation: age, sex, size of hyphema, initial visual acuity (IVA), intraocular pressure (IOP) and fundus examination. The outcome, hyphema resorption time, and occurrence of complications such as rebleeding and secondary glaucoma were recorded and compared between groups. The resorption time was almost the same (4 days) regardless of the treatment modality the patient received. Four (3.3%) patients developed a rebleed, two (5%) in the first (steroid only) group and 2(5%) in the third (control) group. The final visual activities (FVA) were 0.3 log MAR in all (100%) the patients in the second (steroid cyclo) and the third (control) groups, the mean log MAR is 0.05 and 0.035 in the second and third group respectively. However, in the first (steroid only) group 36(90%) patients had FVA of 0.3 log MAR and 4 (10%) had FVA>0.3 log MAR on discharge, the mean log MAR is 0.1. P value of (0.04). The cause of the decline in final visual acuity in these 4 patients was the development of traumatic cataract rather than the treatment used. A total of 14 patients (11.6%) developed a mild to moderate elevation of IOP (23-29 mmHg); 10(25%) in the first (steroid only) group, 2(5%) in the second (steroid cyclo) group and 2(5%) in the third (control) group. In all cases, the IOP returned to the normal either without treatment or with short term Timolol eye drops. In cases of mild simple traumatic hyphemas not exceeding 50%, simple

    Full Text Available Mucocele and traumatic neuroma are two lesions related to the traumatic events; however there is only one reported case in which these two entities were perceived simultaneously. The current study reported a 21-year-old man who complained of painless recurrent swelling, accompanied by paresthesia on his left lower labial mucosa. He had a previous history of similar lesion and had been treated with surgery and cauterization last year. The primary clinical impression was a recurrent mucocele. Microscopic surveys displayed a traumatic neuroma in the vicinity of a mucocele which seems to be arising from the previous surgical treatment.

    Traumatic lumbar hernia describes the extrusion of intraperitoneal or extraperitoneal contents through a defect in the posterolateral abdominal wall caused by a trauma. This is a rare entity and usually diagnosed by computed tomography. A 64-year-old male received an injury on his cervical spinal cord after an accident in which he fell down. He complained of a mass on his left posterolateral back area. We diagnosed the mass as a traumatic lumbar hernia by ultrasonography and confirmed it by computed tomography. We conclude that the ultrasonography can be a useful diagnostic tool for traumatic lumbar hernia

    Traumatic brain injuries (TBI) often involve vascular dysfunction that leads to long-term alterations in physiological and cognitive functions of the brain. Indeed, all the cells that form blood vessels and that are involved in maintaining their proper function can be altered by TBI. This Review focuses on the different types of cerebrovascular dysfunction that occur after TBI, including cerebral blood flow alterations, autoregulation impairments, subarachnoid hemorrhage, vasospasms, blood-brain barrier disruption, and edema formation. We also discuss the mechanisms that mediate these dysfunctions, focusing on the cellular components of cerebral blood vessels (endothelial cells, smooth muscle cells, astrocytes, pericytes, perivascular nerves) and their known and potential roles in the secondary injury cascade. © 2016 Wiley Periodicals, Inc.

    Full Text Available Purpose: The objective of this exhibit is to explain imaging of ACL traumatic injuries and post operative changes.Content: Cruciate ligaments have an extra-synovial and intra-capsular location between which fatty tissue lies. The ACL is best seen on sagittal oblique images with slices oriented parallel to the cortex of the lateral femoral condyle so with extension during examination the ligament should therefore appear taut with an approximate 60 degree angle to the tibial plateau. Following injury, there are primary and secondary signs of ACL tearing which will discussed.Summary: In this exhibit, we present imaging findings of ACL injuries. Information about these findings may permit the radiologist to play a significant role in the diagnosis of the problem and prevention of any additional procedures.

    Tribulin (endogenous monoamine oxidase inhibitor/benzodiazepine receptor binding inhibitor) output was measured in the urine of 18 patients with post-traumatic stress disorder (PTSD) and 13 controls. The level of the two inhibitory activities was highly significantly correlated in the group as a whole. There was no difference between output of either inhibitor in patients and controls. However, when the PTSD group was subdivided according to various psychometric ratings, a pattern of output did emerge. Levels of both inhibitory activities were higher in agitated compared with non-agitated subjects, and lower in extroverts compared with introverts. This finding supports the view that tribulin output is raised in conditions of greater arousal. PMID:3270828

    Full Text Available An 8-month-old male infant had presented with a history of a fall from the crib a fortnight ago. He had developed progressive weakness of both lower limbs. On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

    As part of a special issue of The Journal of Head Trauma Rehabilitation, forensic neuropsychology is reviewed as it applies to traumatic brain injury (TBI) and other types of acquired brain injury in which clinical neuropsychologists and rehabilitation psychologists may be asked to render professional opinions about the neurobehavioral effects and outcome of a brain injury. The article introduces and overviews the topic focusing on the process of forensic neuropsychological consultation and practice as it applies to patients with TBI or other types of acquired brain injury. The emphasis is on the application of scientist-practitioner standards as they apply to legal questions about the status of a TBI patient and how best that may be achieved. This article introduces each topic area covered in this special edition. PMID:19333063

    Traumatic brain injury (TBI) elicits an inflammatory response in the central nervous system (CNS) that involves both resident and peripheral immune cells. Neuroinflammation can persist for years following a single TBI and may contribute to neurodegeneration. However, administration of anti-inflammatory drugs shortly after injury was not effective in the treatment of TBI patients. Some components of the neuroinflammatory response seem to play a beneficial role in the acute phase of TBI. Indeed, following CNS injury, early inflammation can set the stage for proper tissue regeneration and recovery, which can, perhaps, explain why general immunosuppression in TBI patients is disadvantageous. Here, we discuss some positive attributes of neuroinflammation and propose that inflammation be therapeutically guided in TBI patients rather than globally suppressed. PMID:27540166

    Full Text Available A rare case of a posttraumatic extensive ganglion cyst of the anterolateral thigh with connection to the knee joint is presented. A 54- year-old man presented a palpable mass in the anterolateral region of his right thigh with a 15 months existing sense of fullness and tightness. He had an accident with his bicycle 21 months ago. Magnetic resonance imaging (MRI was performed showing a cyst inside the quadriceps femoris muscle between vastus lateralis and intermedius with connection to recessus suprapatellaris and knee joint. In addition MRI detected a traumatic lesion in the quadriceps femoris tendon in the near of the knee joint. The ganglion cyst was 18 cm long and was excised completely. Intraope - ratively, the knee joint connection was confirmed and excised as well. The ganglion cyst was filled with a gelatinous and viscous fluid.

    Full Text Available Traumatic brain injury (TBI occurs when a sudden trauma causes brain damage. Depending on the severity, outcome can be anything from complete recovery to permanent disability or death. Emergency medical services play a dominant role in provision of primary care at the site of injury. Since little can be done to reverse the initial brain damage due to trauma, attempts to prevent further brain damage and stabilize the patient before he can be brought to a specialized trauma care centre play a pivotal role in the final outcome. Recognition and early treatment of hypoten-sion, hypoxemia, and hypoglycemia, objective neurological assessment based on GCS and pupils, and safe transport to an optimal care centre are the key elements of prehospital care of a TBI patient.

  10. Accommodation in mild traumatic brain injury

    Wesley Green, MS

    2010-05-01

    Full Text Available Accommodative dysfunction in individuals with mild traumatic brain injury (mTBI can have a negative impact on quality of life, functional abilities, and rehabilitative progress. In this study, we used a range of dynamic and static objective laboratory and clinical measurements of accommodation to assess 12 adult patients (ages 18-40 years with mTBI. The results were compared with either 10 control subjects with no visual impairment or normative literature values where available. Regarding the dynamic parameters, responses in those with mTBI were slowed and exhibited fatigue effects. With respect to static parameters, reduced accommodative amplitude and abnormal accommodative interactions were found in those with mTBI. These results provide further evidence for the substantial impact of mTBI on accommodative function. These findings suggest that a range of accommodative tests should be included in the comprehensive vision examination of individuals with mTBI.

    Traumatic brain injury (TBI) is a major cause of death and disability that often affects young people. After injury, the degree of recovery can be highly variable, with some people regaining near complete function while others remain severely disabled. Understanding what factors influence recovery is important for counseling patients and families in the acute period after injury and can help guide therapeutic decisions in the acute period following injury. In this review, prognostic algorithms useful for clinicians are discussed. Tools for grading patient outcomes, their role in clinical care and research studies, and their limitations are reviewed. Ongoing work focusing on the development of biomarkers to track TBI recovery and the refinement of clinical outcome metrics is summarized. PMID:27072952

  12. Brain SPECT in severs traumatic head injury

    International Nuclear Information System (INIS)

    The aim of this work was to compare the results of the early brain scintigraphy in traumatic brain injury to the long term neuropsychological behavior. Twenty four patients had an ECD-Tc99m SPECT, within one month after the trauma; scintigraphic abnormalities were evaluated according to a semi-quantitative analysis. The neuropsychological clinical investigation was interpreted by a synthetic approach to evaluate abnormalities related to residual motor deficit, frontal behavior, memory and language disorders. Fourteen patients (58%) had sequela symptoms. SPECT revealed 80 abnormalities and CT scan only 31. Statistical analysis of uptake values showed significantly lower uptake in left basal ganglia and brain stem in patients with sequela memory disorders. We conclude that the brain perfusion scintigraphy is able to detect more lesions than CT and that it could really help to predict the neuropsychological behavior after severe head injury. Traumatology could become in the future a widely accepted indication of perfusion SPECT. (authors)

    2013-01-01

    Traumatic brain injury (TBI) is among the earliest illnesses described in human history and remains a major source of morbidity and mortality in the modern era. It is estimated that 2% of the US population lives with long-term disabilities due to a prior TBI, and incidence and prevalence rates are even higher in developing countries. One of the most feared long-term consequences of TBIs is dementia, as multiple epidemiologic studies show that experiencing a TBI in early or midlife is associated with an increased risk of dementia in late life. The best data indicate that moderate and severe TBIs increase risk of dementia between 2-and 4-fold. It is less clear whether mild TBIs such as brief concussions result in increased dementia risk, in part because mild head injuries are often not well documented and retrospective studies have recall bias. However, it has been observed for many years that multiple mild TBIs as experienced by professional boxers are associated with a high risk of chronic traumatic encephalopathy (CTE), a type of dementia with distinctive clinical and pathologic features. The recent recognition that CTE is common in retired professional football and hockey players has rekindled interest in this condition, as has the recognition that military personnel also experience high rates of mild TBIs and may have a similar syndrome. It is presently unknown whether dementia in TBI survivors is pathophysiologically similar to Alzheimer disease, CTE, or some other entity. Such information is critical for developing preventive and treatment strategies for a common cause of acquired dementia. Herein, we will review the epidemiologic data linking TBI and dementia, existing clinical and pathologic data, and will identify areas where future research is needed. PMID:22776913

  14. MRI features of peripheral traumatic neuromas

    International Nuclear Information System (INIS)

    To describe the MRI appearance of traumatic neuromas on non-contrast and contrast-enhanced MRI sequences. This IRB-approved, HIPAA-compliant study retrospectively reviewed 13 subjects with 20 neuromas. Two observers reviewed pre-operative MRIs for imaging features of neuroma (size, margin, capsule, signal intensity, heterogeneity, enhancement, neurogenic features and denervation) and the nerve segment distal to the traumatic neuroma. Descriptive statistics were reported. Pearson's correlation was used to examine the relationship between size of neuroma and parent nerve. Of 20 neuromas, 13 were neuromas-in-continuity and seven were end-bulb neuromas. Neuromas had a mean size of 1.5 cm (range 0.6-4.8 cm), 100 % (20/20) had indistinct margins and 0 % (0/20) had a capsule. Eighty-eight percent (7/8) showed enhancement. All 100 % (20/20) had tail sign; 35 % (7/20) demonstrated discontinuity from the parent nerve. None showed a target sign. There was moderate positive correlation (r = 0.68, p = 0.001) with larger neuromas arising from larger parent nerves. MRI evaluation of the nerve segment distal to the neuroma showed increased size (mean size 0.5 cm ± 0.4 cm) compared to the parent nerve (mean size 0.3 cm ± 0.2 cm). Since MRI features of neuromas include enhancement, intravenous contrast medium cannot be used to distinguish neuromas from peripheral nerve sheath tumours. The clinical history of trauma with the lack of a target sign are likely the most useful clues. (orig.)

  15. A study of the traumatic bone cyst

    International Nuclear Information System (INIS)

    Traumatic bone cyst is a pathologic cavity that is not lined with epithelium. It is, therefore, not a true cyst. It may be a normal variant rather than a disease process. The etiology of the condition is unknown. This condition is occurred widely ranging ages(2 to 75 years), however, most are found during the second decade of life. Radiographically, this condition is radiolucent lesion with well-defined outline, scalloping of superior margins. Cyst enucleation and curettage is the treatment of choice. The authors compared and analyzed the clinicoradiologic features of the five cases of traumatic bone cyst, diagnosed at the Dental college hospital in Chosun University, Kwangju, Korea. The five cases were shown the followed results; 1. 3 cases occurred in second decade of life and no significant sex differences (M:F, 2:3) All cases occurred in mandible. 2. Two patients complained symptoms, but three cases had no symptom with encountering during routine examination. 3. In 3 of 5 cases, teeth vitality existed except one tooth and no checking of teeth vitality in two cases. 4. All cases didn't have any accurate trauma history, but one case was in orthodontic treatment, another case was postextraction site area. 5. Radiologically, 'scalloping appearance' were evident in all cases; in 3 cases, multilocular tendency and only one case seen intact mandibular canal image. 6. Histologically, all section showed bone trabeculae with ballistic activity, 2 cases showed no epithelial lining, and other 2 cases were seen inflammatory cell infiltration in edematous tissue. 7. Surgical intervention (curettage) was that treatment of choice.

    Full Text Available Background and Aims: Delayed traumatic hematomas and expansion of already detected hematomas are not uncommon. Only few studies are available on risk factors of expanding hematomas. A prospective study was aimed to find out risk factors associated with such traumatic lesions. Materials and Methods: Present study is based on 262 cases of intracerebral hematomas / contusions out of which 43 (16.4% hematomas expanded in size. computerized tomography (CT scan was done in all the patients at the time of admission and within 24 hours of injury. Repeat CT scan was done within 24 hours, 4 days and 7 days. Midline shift if any, prothrombin time, activated partial thromboplastin time, bleeding time, clotting time and platelet counts, Glasgow coma scale at admission and discharge and Glasgow outcome score at 6 months follow up were recorded. Results: Twenty six percent, 11.3 and 0% patients developed expanding hematoma in Glasgow Coma scale (GCS of 8 and below, 9-12 and 13-15 respectively. The chances of expanding hematomas were higher in patients with other associated hematomas (17.4% as compared to isolated hematoma (4.8% (Fisher′s exact results P =0.216. All the cases of expanding hematoma had some degree of midline shift and considerably higher proportion had presence of coagulopathy. The results of logistic regression analysis showed GCS, midline shift and coagulopathy as significant predictors for the expanding hematoma. Thirty nine patients (90.7% of the total expanding hematomas developed within 24 hours of injury. Conclusions: Enlargement of intracerebral hematomas is quite common and majority of them expand early after the injury. These lesions were common in patients with poor GCS, associated hematomas, associated coagulopathy and midline shift.

    Full Text Available Background: Traumatic ulcer is a common form of ulceration occured in oral cavity caused by mechanical trauma, either acute or chronic, resulting in loss of the entire epithelium. Traumatic ulcer often occurs in children that are usually found on buccal mucosa, labial mucosa of upper and lower lip, lateral tongue, and a variety of areas that may be bitten. To properly diagnose the ulcer, dentists should evaluate the history and clinical description in detail. If the lesion is allegedly accompanied by other infections, such as fungal, bacterial or viral infections, microbiological or serological tests will be required. One of the initial therapy given for fungal infection is nystatin which aimed to support the recovery and repair processes of epithelial tissue in traumatic ulcer case. Purpose: This case report is aimed to emphasize the importance of microbiological examination in suspected cases of ulcer accompanied with traumatic fungal infection. Case: A 12-year-old girl came to the clinic of Pediatric Dentistry, Faculty of Dentistry, University of Indonesia on June 9, 2011 accompanied with her mother. The patient who had a history of geographic tongue came with complaints of injury found in the middle of the tongue. The main diagnosis was ulcer accompanied with traumatic fungal infection based on the results of swab examination. Case management: This traumatic ulcer case was treated with Dental Health Education, oral prophylaxis, as well as prescribing and usage instructions of nystatin. The recovery and repair processes of mucosal epithelium of the tongue then occured after the use of nystatin. Conclusion: It can be concluded that microbiological examination is important to diagnose suspected cases of ulcer accompanied with traumatic fungal infection. The appropriate treatment such as nystatin can be given for traumatic fungal infection.Latar belakang: Ulkus traumatic merupakan bentuk umum dari ulserasi rongga mulut yang terjadi akibat trauma

    Ground-state quantum computers mimic quantum mechanical time evolution within the amplitudes of a time-independent quantum state. We explore the principles that constrain this mimicking. A no-cloning argument is found to impose strong restrictions. It is shown, however, that there is flexibility that can be exploited using quantum teleportation methods to improve ground-state quantum computer design.
