Sample records for cardiomegaly

  1. X-ray criteria for assessment of cardiomegaly

    International Nuclear Information System (INIS)

    Cardiomegaly is a clinico-roentgenologic entity, uniting cardiovascular diseases of diverse nature, differing in their pathomorphological structures and pathophysiological characteristics and requiring different therapeutic apporoach. The following X-ray cardiometric criteria for cardiomegaly are accepted: 60-65% increase in the cardio-thoracic segment; 100% enlargement of the relative cardiac volume, as compared to the normal one; increased heart weight to more than 500-550 g in women and 550-600 g in men. These X-ray cardiometric criteria are essential in assessing the indications and in the bypass operative intervention

    A systematic study following infection by various strains of the protozoan parasite, Trypanosoma cruzi, and the simultaneous monitoring of the humoral immune response together with the elicited cellular response, could add greatly to our understanding of differences between strains of this important human pathogen. In that sense, acute and chronic infections with distinct T. cruzi strains (Y, Berenice-78 and ABC) in Beagle dogs were studied through a longitudinal evaluation of immunoglobulin G (IgG), IgG1 and IgG2 isotypes (by ELISA and flow cytometry (FC)), as well as measurements of peripheral blood mononuclear cell (PBMC) proliferation over a 100-week period, and their correlation with cardiomegaly. Our results show that infected animals presenting cardiomegaly showed lower or absent levels of IgG1 during the chronic phase of the infection, when compared to those that did not show an increase in heart weight. In that manner, our results suggest that IgG1 could be used as a marker for cardiac pathogenicity in Chagas disease. PMID:18439688

  3. Establishing the cardiothoracic ratio using chest radiographs in an indigenous Ghanaian population: a simple tool for cardiomegaly screening

    International Nuclear Information System (INIS)

    Cardiothoracic ratio is a simple and cheap tool in the estimation of heart size. It is a useful index of cardiac size evaluation, and a value of 50% is generally considered to indicate the upper limit of normal. This study is to ascertain the normal mean value in cardiothoracic ratio of Ghanaians using chest radiography to serve as baseline for screening for cardiomegaly. Standard postero-anterior radiographs of the -clients/patients were used in the study. The cardiothoracic ratio (CTR) was obtained by dividing the transverse cardiac diameter [sum of the horizontal distances from the right and left lateral-most margins of the heart to the midline (spinous processes of the vertebral bodies)] by the maximum internal thoracic diameter. Systematic sampling with appropriate inclusion and exclusion criteria were used to obtain a sample size of 1989. The mean transverse cardiac diameter and cardiothoracic ratio increased with age. The transverse thoracic diameter increased with age until the sixth decade when it reduced with age. The mean CTR increased gradually with age with females having greater values than males. The mean CTR of the study population were 0.459, 0.467 and 0.452 for the general population, females and males respectively. This study has been able to establish 0.459 as the mean CTR values for Ghanaians. It has also shown the relationship between age and clients /patient’s cardiothoracic ratio which compares favourably with findings of a similar study in Nigeria, a neighbouring country in the West African sub region with similar ethnic and social structure.

    Aortic arch calcification (AoAC) is associated with cardiovascular and all-cause mortality in end-stage renal disease population. AoAC can be simply estimated with an AoAC score using plain chest radiography. The objective of this study is to evaluate the association of AoAC with brachial-ankle pulse wave velocity (baPWV) and cardiomegaly in patients who have undergoing hemodialysis (HD).We retrospectively determined AoAC and cardiothoracic ratio (CTR) by chest x-ray in 220 HD patients who underwent the measurement of baPWV. The values of baPWV were measured by an ankle-brachial index-form device. Multiple stepwise logistic regression analysis was used to identify the factors associated with AoAC score >4.Compared patients with AoAC score ≦4, patients with AoAC score >4 had older age, higher prevalence of diabetes and cerebrovascular disease, lower diastolic blood pressure, higher baPWV, higher CTR, higher prevalence of CTR ≧50%, lower total cholesterol, and lower creatinine level. After the multivariate stepwise logistic analysis, old age, cerebrovascular disease, high baPWV (per 100 cm/s, odds ratio [OR] 1.065, 95% confidence interval [CI] 1.003-1.129, P = 0.038), CTR (per 1%, OR 1.116, 95% CI 1.046-1.191, P = 0.001), and low total cholesterol level were independently associated with AoAC score >4.Our study demonstrated AoAC severity was associated with high baPWV and high CTR in patients with HD. Therefore, we suggest that evaluating AoAC on plain chest radiography may be a simple and inexpensive method for detecting arterial stiffness in HD patients. PMID:27175684

    Full Text Available Introduction. The presence of aortic arch calcification (AoAC and cardiomegaly on chest radiography has been demonstrated as important risk factors for cardiovascular mortality in patients with chronic kidney disease (CKD. However, the interrelationship among AoAC, cardiomegaly, and renal function progression remains unclear. The aim of this study is to assess whether AoAC and cardiomegaly are independently associated with the renal function progression in patients with stages 3–5 CKD. Methods. We retrospectively determined AoAC and cardiomegaly by chest X-ray in 237 patients, followed up for at least three years without entering dialysis and classified into 4 groups according to the presence or absence of AoAC and cardiomegaly. The change in renal function was measured by the slope of estimated glomerular filtration rate (eGFR. Results. Of the 237 patients, the rate of eGFR decline was significantly higher in the group with coexistence of AoAC and cardiomegaly than any other groups. Baseline AoAC and proteinuria were independently associated with eGFR decline. AoAC were independently determined by age, eGFR slope, and cardiomegaly. Conclusions. The coexistence of AoAC and cardiomegaly is associated with faster eGFR decline. AoAC is an independent determinant of renal outcomes in patients with CKD stages 3–5.

  3. A study on findings from simple chest radiographs without any clinical symptoms

    International Nuclear Information System (INIS)

    In this study, the analysis on findings from simple chest radiography (CXR) test with total 1,669 subjects without any special clinical symptom came to the following conclusions: In terms of the general characteristics of subjects hereof, male and female group accounted for 55.2% and 44.8% respectively out of all 1,669 people. Pulmonary disease cases amounted to 249 persons (14.9%) out of all subjects. In the analysis on prevalence rate by age distribution, it was noted that the older age led to the more number of diseases, which was demonstrated by age 34 or younger (6.1%), age 35 ∼ 39 (9.7%), age 40 ∼ 49 (13.3%), and age 50 or older (30.8%). In regard of pulmonary disease alone, the region of onset was represented primarily by right upper lobe, which was followed by both upper lobe and left upper lobe, respectively. In terms of disease types, it was found that most cases were represented by pulmonary nodule (55.0%), which was followed by cardiomegaly (24.5%), CP angle blunting (4.8%), scoliosis (4.6%) tortuous aorta (2.8%), bronchial luminal dilatation(2.4%), and pleural thickening (2.0%). However, dextrocardia, cystic dilation of bronchus, cavitary lesion, and lung collapse accounted for relatively low rate (0.4% respectively). In terms of disease types by sex, it was found that male group accounted for higher percentage of having cardiomegaly, tortuous aorta and scoliosis than the former. In terms of disease types by age distribution, it was noted that age 34 or younger group accounted for higher percentage of scoliosis than any other age groups, while age 40 ∼ 49 group, age 35 ∼ 39 group, and age 50 or older group represented the case of CP angle blunting, pulmonary nodule, and cardiomegaly/tortuous aorta, respectively

  4. Pulmonary edema: radiographic differential diagnosis

    International Nuclear Information System (INIS)

    To evaluate the feasibility of using chest radiography to differentiate between three different etiologies of pulmonary edema. Plain chest radiographs of 77 patients, who were clinically confirmed as having pulmonary edema, were retrospectively reviewed. The patients were classified into three groups : group 1 (cardiogenic edema : n = 35), group 2 (renal pulmonary edema : n = 16) and group 3 (permeability edema : n = 26). We analyzed the radiologic findings of air bronchogram, heart size, peribronchial cuffing, septal line, pleural effusion, vascular pedicle width, pulmonary blood flow distribution and distribution of pulmonary edema. In a search for radiologic findings which would help in the differentiation of these three etiologies, each finding was assessed. Cardiogenic and renal pulmonary edema showed overlapping radiologic findings, except for pulmonary blood flow distribution. In cardiogenic pulmonary edema (n=35), cardiomegaly (n=29), peribronchial cuffing (n=29), inverted pulmonary blood flow distribution (n=21) and basal distribution of edema (n=20) were common. In renal pulmonary edema (n=16), cardiomegaly (n=15), balanced blood flow distribution (n=12), and central (n=9) or basal distribution of edema (n=7) were common. Permeability edema (n=26) showed different findings. Air bronchogram (n=25), normal blood flow distribution (n=14) and peripheral distribution of edema (n=21) were frequent findings, while cardiomegaly (n=7), peribronchial cuffing (n=7) and septal line (n=5) were observed in only a few cases. On plain chest radiograph, permeability edema can be differentiated from cardiogenic or renal pulmonary edema. The radiographic findings which most reliably differentiated these two etiologies were air bronchogram, distribution of pulmonary edema, peribronchial cuffing and heart size. Only blood flow distribution was useful for radiographic differentiation of cardiogenic and renal edema

    To describe radiologic findings of burn-associated persistent candidemia of the thorax. This study included 42 patients with major burns in whom blood culture had shown the presence for more than 24 hours of persistent candidemia. The duration of positive culture for candidiasis ranged from two to 67 days(mean, 15 days). Radiographic(n=42) and thin-section CT findings(n=13) were retrospectively analyzed. The onset, pattern, size, distribution and persistence of parenchymal abnormalities as well as the presence or absence of pleural effusions, mediastinal lymphadenopathy and cardiomegaly were assessed. On chest radiographs, positive findings were noticed in 61.9%(26/42) and on thin-section CT, in 76.9%(10/13). The most frequent radiographic finding was pulmonary nodule(s), observed in 14 patients(33.3%); in 13, these were bilateral. Bronchovascular bundle thickening(n=6, 14.3%), consolidation(n=4, 9.5%), cardiomegaly(n=6, 14.3%) and pleural effusion(n=4, 9.5%) were also observed. Those lesions appeared eight to 129 days(mean, 33 days) after the burn. Radiographic abnormalities persisted for seven to 115(mean, 35) days, regardless of the treatment. Thin-section CT showed parenchymal abnormalities in 10/13 patients(76.9%) and subpleural nodules of less than 1cm in diameter and without halo in all patients. Cardiomegaly, pleural effusion and mediastinal adenopathy were observed on CT in 5(38.5%), 4(30.8%) and 2(15.4%) of the 13 patients, respectively. In a high proportion of patients with burn-associated candidemia, chest radiograph and thin-section CT findings were positive. The most frequent radiographic parenchymal abnormality was multiple bilateral nodules.

    Ten full-term newborn infants with transient myocardial ischemia developed radiographic evidence of cardiomegaly and pulmonary venous congestion within the first few hours of life. In five patients, radiographic findings returned to normal during the first week of life. In the remaining five patients radiographic findings improved within the second week and eventually became normal. Echocardiography done on six patients demonstrated left ventricular dysfunction in all six patients. Those infants with documented perinatal insults tend to have a protracted clinical course with eventual recovery. Pathophysiology and clinical course are discussed. (orig.)

  8. Prenatal MR findings in a case of aneurysm of the vein of Galen

    International Nuclear Information System (INIS)

    We describe a case of aneurysm of the vein of Galen (AVG), which was diagnosed by intrauterine US, MRI and MRA. The baby girl was born at 35 weeks' gestation. She had severe clinical symptoms at birth and died at 29 h of age from intractable congestive heart failure. Intrauterine US detected an intracranial aneurysm and cardiomegaly due to excessive arteriovenous shunting. Intrauterine MRI (SSFSE) confirmed the diagnosis of AVG, and intrauterine MRA (2D-TOF) successfully demonstrated the anatomical structure of the AVG. MRA may be a useful additional sequence to evaluate AVG, and 2D-TOF is thought to be an appropriate technique for scanning fetal AVG. (orig.)

The baby presented with severe progressive hepatic dysfunction and cardiomegaly. Multimodality imaging demonstrated a large hypervascular solitary hepatic mass with marked transhepatic shunting, consistent with rapidly involuting congenital hemangioma. Because medical therapy failed, transarterial and transvenous embolization was performed with the main intention to improve the hepatic perfusion and function. Unfortunately, despite improvement in the cardiac overload, liver function continued to deteriorate. The baby eventually underwent successful liver transplantation. (orig.)

    A 32-year-old Caucasian woman presented with shortness of breath four weeks postpartum. She was known to suffer from systemic lupus erythematosus with cutaneous, joint and minor renal involvement. During pregnancy, the patient had developed nephrotic syndrome for which she was managed with prophylactic anticoagulation and corticosteroid therapy. A leg deep vein thrombosis had arisen following caesarean section following antepartum haemorrhage. Examination revealed a heart murmur, and pulmonary signs. Computed tomography pulmonary angiogram showed cardiomegaly and bilateral pleural effusions but no pulmonary embolus. Echocardiogram demonstrated dilated cardiomyopathy. An initial diagnosis of peripartum cardiomyopathy was considered, with lupus myocarditis and coronary in situ thrombosis among the differential diagnoses.

    Full Text Available The dog is considered the main domestic reservoir for Trypanosoma cruzi infection and a suitable experimental animal model to study the pathological changes during the course of Chagas disease (CD. Vaccine development is one of CD prevention methods to protect people at risk. Two plasmids containing genes encoding a trans-sialidase protein (TcSP and an amastigote-specific glycoprotein (TcSSP4 were used as DNA vaccines in a canine model. Splenomegaly was not found in either of the recombinant plasmid-immunized groups; however, cardiomegaly was absent in animals immunized only with the plasmid containing the TcSSP4 gene. The inflammation of subendocardial and myocardial tissues was prevented only with the immunization with TcSSP4 gene. In conclusion, the vaccination with these genes has a partial protective effect on the enlargement of splenic and cardiac tissues during the chronic CD and on microscopic hearth damage, since both plasmids prevented splenomegaly but only one avoided cardiomegaly, and the lesions in heart tissue of dog immunized with plasmid containing the TcSSP4 gene covered only subepicardial tissue.

    Full Text Available Tuberculosis is generally followed by secondary amyloidosis. The association of primary systemic amyloidosis with tuberculosis is very rare. There is only one case thus far reported in literature. We report such a rare case of primary amyloidosis with tuberculous lymphadenopathy. A 45 year old woman presented at the medicine department of all India institute of medical sciences , New Delhi with on & off erythematous rashes over both eyes for 1 year; low grade fever, fatigue and significant weight loss for 4 months, dysphagia for solid food since 1 month. Main finding on examination were pallor, macroglossia, bilateral periorbital erythematous rashes (racoon eyes, hepatomegaly & cardiomegaly. She had raised serum alkaline phosphatase level. Chest x-ray revealed cardiomegaly. USG abdomen revealed multiple retroperitoneal mesenteric lymph nodes and hepatomegaly. USG guided FNAC from mesenteric lymph node showed acid fast bacillus. Histological examination of liver biopsy showed amyloid deposition on congo red stain. Patient was treated with DOTS category I ATT with Bortezomib and Dexamethasone based weekly chemotherapy.

    Sickle cell anaemia (SCA) is one of the commonest chronic hemolytic anaemias in the Sudan; it is a disease with high mortality and morbidity. This study was conducted aiming to observe the clinical pattern of cardiac abnormalities in children with sickle cell anaemia, and to assess the relationship between the cardiac abnormalities and the severity of the disease. The study was conducted in sickle cell disease clinic at Khartoum Children Emergency Hospital. The study group consisted of 289 patients with sickle cell anaemia, age range from 6 months to 18 years. Data were collected using a questionnaire which include full history, clinical examination findings, chest x-rays, and Electro-cardiography. Tachycardia, systolic murmurs, and cardiomegaly were detected in 28%, 61%, and 54% of patients with SCA respectively. Left ventricular dilatation was observed in 51% of the study group, while right ventricular dilatation was observed in 22% of the patients. Left and right atrial dilatations were observed in 16% and 6% of the patients respectively. Contractility, ejection fraction (EF) were found almost always normal in all study subjects. Chamber dilatations were not associated with any abnormality in Left ventricular functions. Hemglobin (Hb) levels correlated negatively with cardiomegaly. Left Ventricular End Diastolic Dimension (LVEDD) correlates negatively with Hb levels and positively with the severity index. Only four patients (1%) had abnormal valves. In conclusion, cardiac abnormalities in patients with SCA correlate with the age of the patients and the severity of the disease. PMID:27493331

    The landmark 1933 case report from Massachusetts General Hospital by Bland, White and Garland (Am Heart J 8:787-801) described a 3-month-old child with progressive feeding problems, cardiomegaly on chest radiography, and EKG evidence of left ventricular damage. Of interest was the fact that the vigilant father of the infant was Aubrey Hampton, a radiologist and future chairman of radiology at Massachusetts General Hospital. At autopsy, the left coronary artery originated from the pulmonary artery rather than from the aorta. Effective treatment for this condition was not available until 1960 when Sabiston, Neill and Taussig showed that the blood flowed from the left coronary artery toward the pulmonary artery. The anomalous left coronary artery was ligated at its junction with the pulmonary artery and the child survived. This historical review of Bland-White-Garland syndrome, now known as anomalous left coronary artery arising from the pulmonary artery (ALCAPA), stresses the continued diagnostic significance of cardiomegaly on chest radiography and EKG changes suggesting left ventricular damage in 2- to 3-month-old infants with feeding intolerance or irritability. With a high index of suspicion, an echocardiogram can be obtained to confirm the diagnosis. Modern surgical methods involve left coronary artery translocation and afford excellent outcomes. (orig.)

    Full Text Available Abstract Background Investigation of pulmonary pathology with computed tomography also allows visualisation of the heart and major vessels. We sought to explore whether clinically relevant cardiac pathology could be identified on computed tomography pulmonary angiograms (CTPA requested for the exclusion of pulmonary embolism (PE. 100 consecutive CT contrast-enhanced pulmonary angiograms carried out for exclusion of PE at a single centre were assessed retrospectively by two cardiologists. Findings Evidence of PE was reported in 5% of scans. Incidental cardiac findings included: aortic wall calcification (54%, coronary calcification (46%, cardiomegaly (41%, atrial dilatation (18%, mitral annulus calcification (15%, right ventricular dilatation (11%, aortic dilatation (8% and right ventricular thrombus (1%. Apart from 3 (3% reports describing cardiomegaly, no other cardiac findings were described in radiologists' reports. Other reported pulmonary abnormalities included: lung nodules (14%, lobar collapse/consolidation (8%, pleural effusion (2%, lobar collapse/consolidation (8%, emphysema (6% and pleural calcification (4%. Conclusions CTPAs requested for the exclusion of PE have a high yield of cardiac abnormalities. Although these abnormalities may not have implications for acute clinical management, they may, nevertheless, be important in long-term care.

    Objective. To study the change of taurine transport, and taurine transporter (TAUT) and cysteine sulfinate decarboxylase (CSD) Mrna contents in hypertension and hypertensive cardiomegaly. Methods. Taurine content was determined with a amino acid analyser. Taurine uptakes were determined by (H)-taurine incubation. The content of TAUT and CSD Mrna levels were measured by competitive quantitative RT-PCR in myocardial and vascular tissues of L-Nω-nitro-arginine (L-NNA)-in-duced hypertensive rats. Results. After the treatment of rats with L-NNA for 28 days, myocardial and vascular taurine contents decreased by 11% and 15% (P<0.05), respectively, and plasma taurine level increased by 13%(P<0.05). Myocardil and vascular Vmax of taurine uptake reduced by 30% and 19% (P<0.05), respec-tively. Their Km of taurine uptake increased by 36% and 17% (P<0.05). Myocardial and vascular TAUT Mrna content decreased by 22% and 19% (P<0.05), respectively, but CSD Mrna content increased by 22% (P<0.05)and 30% (P<0.01), respectively. Conclusions. This study suggests that there is a decreased taurine content in myocardial and vascular tissues of L-NNA-induced hypertension rats. The decreased taurine content may result from the decreased number of TAUT on the cell membrane mainly due to the down-regulation of TAUT gene and TAUT affinity eansed by hypertension and hypertensive cardiomegaly.

  19. Prevalence of heart disease in symptomatic cats: an overview from 1998 to 2005

    International Nuclear Information System (INIS)

    A total of 408 cats with various cardiovascular problems has been presented to two investigational clinics during the last 8 years. The number of yearly examinations has steadily increased during this period. Definitive cardiovascular disease was diagnosed in 287 cats, whereby hypertrophic cardiomyopathy (HCM) was the most common diagnosis with 67.6%. Congenital cardiovascular malformations were found in 11.8% of the cases. Ventricular septal defect (VSD) was the most frequent anomaly, in contrast to previously published studies. The ECG was found to be relatively non-specific and insensitive for the diagnosis of heart disease. Its usefulness lies in the recognition and diagnosis of cardiac arrhythmias. The radiographically recognized changes were also non-specific for certain heart diseases. Radiographs of the thorax are especially useful in the evaluation of cardiomegaly, and secondary signs of congestion

  20. Diagnostic radiology and nuclear cardiology: their use in assessment of equine cardiovascular disease

    International Nuclear Information System (INIS)

    Survey thoracic radiography, although limited by physical considerations in the adult horse, can supply clinically useful information about changes in cardiac size and function. The radiographic features of cardiomegaly, altered pulmonary circulation, pulmonary edema, and pleural effusion as manifested in the horse are discussed. Nuclear cardiology can be performed in the standing horse. The initial transit of a radioactive tracer through the central circulation provides information about cardiac chamber size, efficiency of ventricular contraction, valvular competence, and presence of intracardiac or extracardiac shunts. Computer analysis of similar studies allows quantitation of several useful cardiac parameters including ventricular ejection fraction and shunt size (QP/QS). Gated blood pool nuclear studies are better suited to evaluate cardiac response to stress but are difficult to perform in the conscious horse with standard imaging equipment

    An Argentine boa (Boa constrictor occidentalis) of 5 yr 7 mo of age was presented for respiratory problems and regurgitation. Radiographs revealed evidence of cardiomegaly and pneumonia. Blood smear examination revealed the presence of intracytoplasmic inclusion bodies in peripheral lymphocytes, consistent with inclusion body disease. Cultures of a tracheal wash sample resulted in growth of Ochrobactrum intermedium and Pseudomonas putida. Echocardiographic examination revealed a large vegetative lesion on the right atrioventricular valve with valvular insufficiency, a mildly dilated right atrium, and pulmonary hypertension. Postmortem examination confirmed the presence of pneumonia and bacterial endocarditis with dystrophic mineralization of the right atrioventricular valve, associated with different bacteria than those cultured from the tracheal wash. The present case is the first report of endocarditis in a boa constrictor and contributes to the rare reports of cardiac disease in snakes. PMID:25831585

  4. Radiographic findings of mycoplasma pneumonia in adult

    International Nuclear Information System (INIS)

    Mycoplasma pneumonia has known to be a not uncommon disease. However, the differential diagnosis of mycoplasm pneumonia with other viral pneumonia is difficult because of its variable clinical symptoms and atypical radiologic findings. A retrospective review was made of plain chest radiologic findings and clinical manifestations of 33 patients, who were admitted at Yonsei University Hospital from January, 1985 to February, 1990. The most prevalent age was 4th decade (33%) and main symptoms were cough (24/33), fever (2/33) and sputum (20/22). The most frequent season was winter (50%). The radiologic patterns were predominently interstitial (15/33), combined (13/33) and predominently alveolar (5/33) lesion. In alveolar infiltration cases (n 18), unilateral single lobe involvement was the most common (17/18) and left lower lobe (8/18) was predominently involved. Associated radiologic findings were hilar lymphadenopathy (4/33), pleural effusion (4/33) and cardiomegaly (7/33)

    Full Text Available Abstract There have been few case reports which discuss a relationship between warfarin overdose and aortic pseudoaneurysm leakage. We report the case of a female receiving warfarin who presented with dsypnea. Her international normalized ratio was > 10. Chest radiograph revealed cardiomegaly, and chest computed tomography (CT showed a bulging pouch-like lesion below the aortic arch greater than 6x6 cm in size and a fluid collection suggesting blood in the pericardium. Thoracic endovascular aneurysm repair (TEVAR was successfully performed by a cardiovascular surgeon. Aortic pseudoaneurysm formation and leakage may be considered as a rare complication in patients receiving warfarin therapy. Further study regarding warfarin use and the incidence of pseudoaneurysm leakage is needed.

    Full Text Available We report a case of severe intrauterine hemolysis caused by sole anti-E alloimmunization. A 36-year-old multipara woman presented with hydrops fetalis at 27 weeks of gestation. She had a history of previous neonatal death. In this pregnancy, she was found to have very high titer of anti-E antibody. Ultrasonography detected marked skin edema, cardiomegaly, hepatosplenomegaly, pleural effusion, ascites, placentomegaly, and polyhydramnios. The Doppler peak systolic velocity in the middle cerebral artery was 0.8 m/s, indicating severe fetal anemia. Multiple intrauterine transfusions for the anemic fetus were administered. However, persistent severe fetal anemia and placentomegaly caused poor neonatal death and mirror syndrome in the mother. Uncommon red blood cell alloimmunization has to be watched for early in any population, especially in a woman with a history of unexplained perinatal loss.

    @@ Twin-twin transfusion syndrome (TTTS) is a serious obstetric complication, occurring in about 15% of monochorionic (MC) twin pregnancies. If untreated, the prognosis is poor, with an overall perinatal mortality of 80%.1 It is now clear that TTTS is the result of an unbalanced unidirectional blood flow through placental arteriovenous anastomoses (also termed deep anastomoses) between the two fetal circulations.2 The donor twin progressively becomes anemic, and develops growth restriction, oliguria, and oligohydramnios/anhydramnios; whereas the recipient becomes plethoric and polyuric, and develops congestive heart failure, cardiomegaly, polyhydramnios and fetal hydrops. Preterm labor is common because of gross polyhydramnios, and further deteriorations will lead to intrauterine death of both twins.

  8. Demonstration of chronic recurrent pulmonary emboli with spiral CT

    International Nuclear Information System (INIS)

    Chronic recurrent pulmonary emboli may lead, in rare cases, to progressive pulmonary arterial hypertension which cannot be treated medically. These patients may be helped by bilateral pulmonary thrombenarterectomy. The value of spiral CT in the diagnosis of this condition was demonstrated in 31 patients. In 12 patients, thrombi could be shown to be cause of the pulmonary arterial hypertension. Indirect criteria were vascular occlusions, changes in calibre and mural irregularities which were shown in varying degrees in all patients. In 22 of 31 patients there was non-homogeneity of perfusion with greater opacification of the perfused lung parenchyma. In 11 patients scars related to pleural surfaces were seen. Typical changes of right heart insufficiency (cardiomegaly, widened central pulmonary arteries) were shown in all patients by CT. (orig.)

To address this question, T cell lines were developed from chronic chagasic patients peripheral blood mononuclear cells (PBMC and cloned. These T cell clones (TCC were analyzed phenotypically with monoclonal antibodies by the use of a fluorescence microscope. The surface phenotype of the TCC from the asymptomatic patient were predominantly CD4 positive (86%. On the contrary, the surface phenotype CD8 was predominant in the TCC from the patients suffering from cardiomegaly with right bundle branch block (83%, bradycardia with megacolon (75 % and bradycardia (75%. Future studies will be developed in order to identify the antigens eliciting these T cell subpopulations.

    Full Text Available Abstract Background Giant placental chorioangiomas have been associated with a number of severe fetal complications and high perinatal mortality. Case presentation We report a case of giant chorioangioma with fetal hydrops, additionally complicated by severe anemia, mild cardiomegaly with hyperdinamic heart circulation and maternal mirror syndrome. Intrauterine blood transfusion and amniodrainage was performed at 29 weeks. Worsening of the fetal and maternal condition prompted us to proceed with delivery at 29 + 5 weeks. The newborn died 3 hours later due to pulmonary hypoplasia and hemodynamic failure. Maternal course was favourable, mirror syndrome resolved in the second day and the patient was discharged four days following delivery. Conclusions In the case described here, fetal condition got worse despite of the anemia correction and amniodrainage. Our outcome raises the issue whether additional intrauterine clinical intervention, as intersticial laser, should have been performed to stop further deterioration of the fetal condition when progressive severe hydrops develops.

    Introduction: Cardiac rhabdomyoma is type of benign myocardial tumor that is the most common fetal cardiac tumor. Cardiac rhabdomyomas are usually detected before birth or during the first year of life. They account for over 60% of all primary cardiac tumors. Case report: A 6 month old child with coughing and obstruction in breathing, was hospitalized in the Pediatric Clinic in UCCK, Pristine. The difficulty of breathing was heard and the pathological noise of the heart was noticed from the pediatrician. In the echo of the heart at the posterior and apico-lateral part of the left ventricle a tumoral mass was presented with the dimensions of 56 × 54 mm that forwarded the contractions of the left ventricle, the mass involved also the left ventricle wall and was not vascularized. The right ventricle was deformed and with the shifting of the SIV on the right the contractility was preserved. Aorta, the left arch and AP were normal with laminar circulation. The pericard was presented free. Radiography of thoracic organs was made; it resulted on cardiomegaly and significant bronchovascular drawing. It was completed with an MRI and it resulted on: Cardiomegaly due to large tumoral mass lesion (60×34 mm) involving lateral wall of left ventricle. It was isointense to the muscle on T1W images, markedly hyperintense on T2W images. There were a few septa or bant like hypointensities within lesion. On postcontrast study it showed avid enhancement. The left ventricle volume was decreased. Mild pericardial effusion was also noted. Surgical intervention was performed and it resulted on the histopathological aspect as a huge infantile rhadbomyoma. Conclusion: In most cases no treatment is required and these lesions regress spontaneously. Patients with left ventricular outflow tract obstruction or refractory arrhythmias respond well to surgical excision. Rhabdomyomas are frequently diagnosed by means of fetal echocardiography during the prenatal period. PMID:27147810

    We observed patients in whom the fluid collection in the right lateral portion of the superior aortic recess on computed tomography (CT) scans mimicked a right anterior mediastinal mass on chest PA radiographs. The purpose of this study was to assess chest PA and CT features of these patients. All chest PA radiographs and CT scans in 9 patients were reviewed by two radiologists on a consensus basis; for the presence of pleural effusion, pulmonary edema and heart size on chest PA radiographs. For the portion of the fluid collection in the superior aortic recess (SAR), a connection between the right lateral portion of the SAR (rSAR) and posterior portion of the SAR (pSAR) on CT scans, and the distance between the right lateral margin of the rSAR and the right lateral margin of the superior vena cava. Fluid collection in the rSAR on CT scans caused a right anterior mediastinal mass or a bulging contour on chest PA radiographs in all women patients. All patients showed cardiomegaly, five patients had pleural effusion, and two patients had mild pulmonary edema. Further, eight patients showed a connection between the rSAR and the pSAR. The characteristic features of these patients are the right anterior mediastinal mass-like opacity due to fluid collection in the rSAR, are bulging contour with a smooth margin and cardiomegaly regardless of pulmonary edema on the chest PA radiographs, and fluid connection between the rSAR and the pSAR on CT scans.

    Pompe disease is a rare autosomal recessive disease caused by the deficiency of acid alpha-glucosidase (GAA), which is required for the degradation of lysosomal glycogen. Glycogen accumulation in heart, muscle and liver eventually leads to muscle weakness, hepatomegaly and cardiomegaly. Although an approved therapy does not exist, the efficacy of enzyme replacement therapy (ERT) has recently been reported in multinational trials in Europe and the US. Here, we present data on the efficacy of recombinant human acid alpha-glucosidase (rhGAA) (provided by Genzyme Corporation) in a patient with Pompe disease. At 5 months of age, motor delay (could not raise his head) and cardiomegaly were observed. A definite diagnosis of Pompe disease was made at 8 months of age after the accumulation of glycogen in a muscle biopsy specimen was observed. This was confirmed by low GAA activity. Since then, motor delay predominated and he was unable to sit independently by age 2.5 years. Every 2 weeks, 20 mg/kg of rhGAA was infused intravenously. To assess the effectiveness, chest X-ray, echocardiography and auditory brain response were recorded. The patient was administered rhGAA for 26 months from 2 years and 8 months of age. Following the initiation of ERT, hepatomegaly and cardiac function (ejection fraction) were rapidly improved and motor function was gradually improved. At 4 years and 10 months, the patient could walk with support. No adverse event has been observed. It can be concluded that ERT with rhGAA is an effective and safe regimen for this case.

    International Nuclear Information System (INIS)

    Eighteen cats were exposed to Dirofilaria immitis infected mosquitoes. Thoracic radiography was performed prior to exposure and at 5, 7, and 9 month intervals following exposure. Immunologic testing for adult heartworm antigen was performed on days 168, 195, 210, 224, 237, 254 and 271 post infection. Necropsies were performed on all cats. Adult heartworms were found in 61% of the exposed cats. Radiographic findings in heartworm positive cats included bronchointerstitial lung disease, lobar pulmonary arterial enlargement and pulmonary hyperinflation. In most heartworm positive cats, lobar arterial enlargement resolved as the disease progressed while pulmonary hyperinflation progressively became more common. Pulmonary patterns in heartworm positive cats remained abnormal throughout the study while abnormal pulmonary patterns resolved in over 50% of the heartworm negative cats. Cardiomegaly was seen in less than 50% of the cats with adult heartworms at necropsy. This study suggests that the radiographic appearance of heartworm disease is variable and radiographic changes are dependent on the time post infection at which cats are evaluated. Echocardiographic examinations were randomly performed on 16 of 18 cats. Heartworms were identified in 7 cats. No false positive identifications were made. Persistent pulmonary disease accompanied by resolving vascular disease in heartworm cats with pulmonary hyperinflation may be difficult to distinguish from cats with feline allergic lung. Echocardiograms may be helpful in identifying adult heartworms in cats in which the radiographic signs or immunodiagnostic data are insufficient to provide a diagnosis

  16. Carlos Chagas Discoveries as a Drop Back to Scientific Construction of Chronic Chagas Heart Disease

    Full Text Available Abstract The scientific construction of chronic Chagas heart disease (CCHD started in 1910 when Carlos Chagas highlighted the presence of cardiac arrhythmia during physical examination of patients with chronic Chagas disease, and described a case of heart failure associated with myocardial inflammation and nests of parasites at autopsy. He described sudden cardiac death associated with arrhythmias in 1911, and its association with complete AV block detected by Jacquet's polygraph as Chagas reported in 1912. Chagas showed the presence of myocardial fibrosis underlying the clinical picture of CCHD in 1916, he presented a full characterization of the clinical aspects of CCHD in 1922. In 1928, Chagas detected fibrosis of the conductive system, and pointed out the presence of marked cardiomegaly at the chest X-Ray associated with minimal symptomatology. The use of serological reaction to diagnose CCHD was put into clinical practice in 1936, after Chagas' death, which along with the 12-lead ECG, revealed the epidemiological importance of CCHD in 1945. In 1953, the long period between initial infection and appearance of CCHD was established, whereas the annual incidence of CCHD from patients with the indeterminate form of the disease was established in 1956. The use of heart catheterization in 1965, exercise stress testing in 1973, Holter monitoring in 1975, Electrophysiologic testing in 1973, echocardiography in 1975, endomyocardial biopsy in 1981, and Magnetic Resonance Imaging in 1995, added to the fundamental clinical aspects of CCHD as described by Carlos Chagas.

    A 68-year-old woman presented to the emergency department owing to exertional dyspnoea and bilateral leg oedema for 3 weeks. Her vital signs included the following: heart rate of 95 bpm, respiratory rate of 24 breaths/min, oxygen saturation of 73% on room air and a blood pressure of 184/108 mm Hg. Physical examination revealed tachypnoea with clear lungs to auscultation, elevated jugular veins, cyanosis and bilateral pitting oedema. A chest X-ray demonstrated cardiomegaly without obvious pulmonary oedema. A CT of the chest was negative for pulmonary embolus; however, the scan did reveal a large right ventricular (RV) mass. An echocardiogram with bubble study confirmed a patent foramen ovale with significant right-to-left shunting and a large RV mass that significantly obstructed the pulmonary outflow tract. A cardiac biopsy revealed a low-grade neuroendocrine tumour. The patient underwent successful debridement and adjuvant chemotherapy. She improved greatly and was asymptomatic at a 9-month follow-up visit. PMID:26969366

    Inter- and intraobserver variation and diagnostic accuracy in estimation of heart size and pulmonary vasculature were evaluated for conventional film-screen technique and image intensifier photofluorography. Interpretation of 218 p.a. and lateral chest films by both imaging techniques was performed independently by 4 readers. Heart size relative to body surface area measured from the plain chest films was used as the reference in cardiac size determination. Overall diagnostic accuracies of conventional radiography and image intensifier photofluorography for cardiomegaly were close to each other, 0.70 vs 0.68, respectively. Specificity of film-screen radiography was better than that of photofluorography (0.92 vs 0.84, p<0.05). Interobserver agreement was poor both in assessment of the heart size and pulmonary vasculature (range of kappa coefficients 0.18-0.59) while the intraobserver consistency (kappa coefficients 0.60-0.85) was good to excellent. The results suggest a limited usefulness of visual assessment of heart size and pulmonary vasculature in chest roentgenographs. (orig.).

    Full Text Available Background: Infantile-onset Pompe disease is a rare genetic and lethal disorder which is caused by the lack of acid alpha-glucosidase activity (GAA. The aim of our study was to identify the demographic and clinical characteristics, and natural history of these patients. Materials and Methods: In this retrospective study, clinical file of 15 patients diagnosed with infantile-onset Pompe disease whose symptoms started before the age of 12 months were studied. Diagnosis was based on clinical history, physical examination and diagnostic parameters in chest X-ray, echocardiogram, electrocardiogram and biochemical tests after rule out the other metabolic and neuromuscular disorders. Results: Sixty percent of the patients were male and 40% were female. The mean age at the onset of symptoms was 78 days (range: 3-150 days. Most frequent clinical and paraclinical symptoms were cardiomegaly, hypotonia, hyporeflexia, macroglossia, failure to thrive, hepatomegaly, and feeding problems, respectively. The mean age at the time of death was 5.96 months (range: 4-8 months, and all patients died before one year of age. Muscle enzymes including AST, ALT, LDH, and CPK were elevated in all patients. Due to the lack of availability, enzyme replacement therapy was not possible for any patient. Conclusion: The study showed that despite the supportive measures and no specific treatment, the clinical course is not significantly different with similar studies and the overall prognosis of this form of disease is very poor and disappointing.

    Full Text Available This study investigated the profiling of polycyclic aromatic hydrocarbon- (PAH- induced genotoxicity in cell lines and zebrafish. Each type of cells displayed different proportionality of apoptosis. Mitochondrial DNA (mtDNA copy number was dramatically elevated after 5-day treatment of fluoranthene and pyrene. The notable deregulated proteins for PAHs exposure were displayed as follows: lamin-A/C isoform 3 and annexin A1 for benzopyrene; lamin-A/C isoform 3 and DNA topoisomerase 2-alpha for pentacene; poly[ADP-ribose] polymerase 1 (PARP-1 for fluoranthene; and talin-1 and DNA topoisomerase 2-alpha for pyrene. Among them, lamin-A/C isoform 3 and PARP-1 were further confirmed using mRNA and protein expression study. Obvious morphological abnormalities including curved backbone and cardiomegaly in zebrafish were observed in the 54 hpf with more than 400 nM of benzopyrene. In conclusion, the change of mitochondrial genome (increased mtDNA copy number was closely associated with PAH exposure in cell lines and mesenchymal stem cells. Lamin-A/C isoform 3, talin-1, and annexin A1 were identified as universal biomarkers for PAHs exposure. Zebrafish, specifically at embryo stage, showed suitable in vivo model for monitoring PAHs exposure to hematopoietic tissue and other organs.

    Full Text Available Anabolic steroid use is becoming increasingly more popular in the United States. Many deleterious effects have been described in the literature, yet there is still much to be understood. Our case describes a severe cardiomyopathy as a result of an extensive anabolic-androgenic steroid regimen in a weightlifter. A 38-year old male with no past medical history presented to our emergency department complaining of worsening dyspnea over two weeks’ duration. Pertinent findings showed a patient in atrial fibrillation with marked jugular venous distension, extensive pulmonary crackles, and lower extremity edema. Diagnostic evaluation included imaging demonstrating cardiomegaly with marked pulmonary edema. Echocardiography showed a severely reduced left ventricular ejection fraction of 16% with severe biventricular failure and biatrial and biventricular enlargement. Our patient ultimately admitted to the use of a “sophisticated” anabolic steroid regimen, including using trenbolone enanthate, testosterone enanthate, sustanon, stanozolol, oxandrolone, clenbuterol, as well as tamoxifen and anastrozole. Clinic follow-up three weeks after the initiation of heart failure medications with discontinuation of the steroid regimen showed improvement in his cardiac function with a left ventricular ejection fraction of 38%. Our case demonstrates the possibility of a severe cardiomyopathy as a result of anabolic steroid use. It also suggests that prompt discontinuation of such substances can lead to reversibility of the condition. Our case also emphasizes the complexity of a steroid regimen in an abuser.

    SP-C-deficient (SP-C -/-) mice developed a severe pulmonary disorder associated with emphysema, monocytic infiltrates, epithelial cell dysplasia, and atypical accumulations of intracellular lipids in type II epithelial cells and alveolar macrophages. Whereas alveolar and tissue surfactant phospholipid pools were increased, levels of other surfactant proteins were not altered (SP-B) or were modestly increased (SP-A and SP-D). Analysis of pressure-volume curves and forced oscillatory dynamics demonstrated abnormal respiratory mechanics typical of emphysema. Lung disease was progressive, causing weight loss and cardiomegaly. Extensive alveolar remodeling was accompanied by type II cell hyperplasia, obliteration of pulmonary capillaries, and widespread expression of alpha-smooth muscle actin, indicating myofibroblast transformation in the lung parenchyma. Dysplastic epithelial cells lining conducting airways stained intensely for the mucin, MUC5A/C. Tissue concentrations of proinflammatory cytokines were not substantially altered in the SP-C (-/-) mice. Production of matrix metalloproteinases (MMP-2 and MMP-9) was increased in alveolar macrophages from SP-C (-/-) mice. Absence of SP-C caused a severe progressive pulmonary disorder with histologic features consistent with interstitial pneumonitis. PMID:12519727

  4. Fractures in children with Pompe disease: a potentiallong-term complication

    International Nuclear Information System (INIS)

    Pompe disease (glycogen storage disease type II or acid maltase deficiency) is an autosomal recessive disorder caused by deficiency of the lysosomal enzyme acid α-glucosidase (GAA). Classic infantile-onset disease, characterized by cardiomegaly and profound weakness, leads to death in the first year of life from cardiorespiratory failure. Reversal of cardiomyopathy and improved motor function have been shown in clinical trials of rhGAA enzyme replacement therapy (ERT) with alglucosidase alfa (Myozyme), recently approved for clinical use. Increased survival potentially unmasks long-term complications of this previously lethal disease, including risk of skeletal fracture, recently identified at our institution and not previously reported in children with Pompe disease. To report the risk of fracture in children with Pompe disease with increased survival with ERT. We present four cases of fracture in patients with classic infantile Pompe disease treated with ERT at our institution, and review a study database for additional reports of fracture in this population. We review 19 fractures in 14 children with Pompe disease on ERT. Radiologists should be familiar with and vigilant for the association of fractures and increased survival on ERT in children with Pompe disease. We discuss potential mechanisms, implications for radiographic surveillance, potential intervention, and needs for further research. (orig.)

  5. The diagnostic value of myocardial perfusion for diagnostics of the ischemic cardiomyopathy and hypertensive heart disease

    International Nuclear Information System (INIS)

    Objective of this study was to detect regional myocardial perfusion defects performing 99mTc-MIBI myocardial perfusion imaging and to compare the results with echocardiography for differential diagnostics of the ischemic and hypertensive cardiomyopathy until coronary angiography will be performed. In total 50 patients with cardiomegaly have been evaluated: 18 patients with hypertensive cardiomyopathy (Ist group), 15 - with ischemic and hypertensive cardiomyopathy (IInd group) and 17 patients with ischemic cardiomyopathy (IIIrd group). All patients underwent 2D echocardiography examination and 99mTc-MIBI myocardial perfusion imaging before coronary angiography was done. Thickness of interventricular septum, myocardial mass and relative wall thickness were statistically significantly smaller in the IIIrd group of patients in comparison with the Ist and the IInd group of patients. Logistic regression model including selected data from myocardial perfusion imaging with 99mTc-MIBI in combination with selected echocardiography data enables prognosis of coronary arteries stenosis with 91.2% sensitivity and 93.8% specificity.

    Histiocytoid cardiomyopathy (Histiocytoid CM) is a rare form of cardiomyopathy observed predominantly in newborn females that is fatal unless treated early in life. We have performed whole exome sequencing on five parent-proband trios and identified nuclear-encoded mitochondrial protein mutations in three cases. The molecular genetic basis of Histiocytoid CM remains unknown despite several hypotheses in medical literature. The findings presented in this manuscript may represent components of genetic etiologies for this heterogeneous disease. Two probands had de novo non-sense mutations in the second exon of the X-linked nuclear gene NDUFB11. A third proband was doubly heterozygous for inherited rare variants in additional components of complex I, NDUFAF2 and NDUFB9, confirming that Histiocytoid CM is genetically heterogeneous. In a fourth case, the proband with Histiocytoid CM inherited a mitochondrial mutation from her heteroplasmic mother, as did her brother who presented with cardiac arrhythmia. Strong candidate recessive or compound heterozygous variants were not found for this individual or for the fifth case. Although NDUFB11 has not been implicated before in cardiac pathology, morpholino-mediated knockdown of ndufb11 in zebrafish embryos generated defective cardiac tissue with cardiomegaly, looping defects, and arrhythmia which suggests the role of NDUFB11 in the pathogenesis of this abnormal cardiac pathology. Taken together, the unbiased whole exome sequencing approach confirms the suspected genetic heterogeneity of Histiocytoid CM. Therefore, the novel NDUFB11 mutation may cause a complex 1 deficiency in synergy with additional unknown mtDNA variants. PMID:25921236

    Between January 1969 and May 1990, 100 patients were operated on for discrete subaortic stenosis. Three patients died in the perioperative period. Patients with intrinsic lesions, prosthetic replacement, or extensive operative remodeling of the aortic valve were excluded from the analysis. The 67 remaining patients had a median follow-up of 62 months. Preoperatively, 8 patients had aortic valve competence, 51 had mild incompetence, and 8 patients moderate aortic valve incompetence. At follow-up mild incompetence persisted in 27 and moderate incompetence in 6 patients. In 1 patient it worsened from no incompetence to mild and in another patient from mild to moderate. The probability of aortic incompetence at follow-up was significantly and simultaneously related (multivariate ordinal logistic model) to (1) older age at operation (logarithm of months, p = 0.007), (2) higher preoperative gradient (third power of milligrams of mercury, p = 0.0004), (3) preoperative cardiomegaly (p = 0.04), and (4) surgical myectomy (p = 0.002). There was an interaction between age and gradient (p = 0.03). Two nomograms are proposed as a generalizable aid to decision making. The data support the policy of early repair of subaortic stenosis.

    From 1994 to 1999, 16 captive African hedgehogs (Atelerix albiventris), from among 42 necropsy cases, were diagnosed with cardiomyopathy. The incidence of cardiomyopathy in this study population was 38%. Fourteen of 16 hedgehogs with cardiomyopathy were males and all hedgehogs were adult (>1 year old). Nine hedgehogs exhibited 1 or more of the following clinical signs before death: heart murmur, lethargy, icterus, moist rales, anorexia, dyspnea, dehydration, and weight loss. The remaining 7 hedgehogs died without premonitory clinical signs. Gross findings were cardiomegaly (6 cases), hepatomegaly (5 cases), pulmonary edema (5 cases), pulmonary congestion (4 cases), hydrothorax (3 cases), pulmonary infarct (1 case), renal infarcts (1 case), ascites (1 case), and 5 cases showed no changes. Histologic lesions were found mainly within the left ventricular myocardium and consisted primarily of myodegeneration, myonecrosis, atrophy, hypertrophy, and disarray of myofibers. All hedgehogs with cardiomyopathy had myocardial fibrosis, myocardial edema, or both. Other common histopathologic findings were acute and chronic passive congestion of the lungs, acute passive congestion of the liver, renal tubular necrosis, vascular thrombosis, splenic extramedullary hematopoiesis, and hepatic lipidosis. This is the first report of cardiomyopathy in African hedgehogs. PMID:11021439

    Full Text Available Determining the size of the heart is important for evaluating cardiac patients, because the increase of the cardiac silhouette in the chest radiography can be indicative of heart disease. The vertebral heart size (VHS method is useful because it allows objective assessment of the limits of cardiac silhouette, and can help assess cardiomegaly and document changes in heart size in response to treatment or disease progression. The aim of this study was to compare VHS values of Maine Coon cats (MCC with values cited in the literature (7.5 ± 0.3 vertebrae obtained in non Maine Coon cats (NMCC. Sixty three MCC underwent the physical examination, electrocardiography, echocardiography, laboratory tests (blood count, biochemistry, including liver and kidney function, and total T4, as well as measurement of blood pressure. Faced with normal results, the cats were positioned in right lateral decubitus (right laterallateral projection, to perform chest radiography. The radiographic examinations were performed using the Fuji computed radiography system. The values of VHS found in the animals of this study were 7.61 ± 0.34 vertebrae with a minimum of 6.9 and of maximum 8.5 vertebrae. Statistical analysis performed by Student’s t test identified a significant difference between the values obtained in this study with those in the literature (p = 0.03 for non Maine Coon cats. The highest values of VHS obtained in MCC may be associated with the size of this giant breed.

  11. Clinical features and MRI characteristics in patients with cardiac amyloidosis

    International Nuclear Information System (INIS)

    Objective: To observe the clinical features and cardiac magnetic resonance (CMR) imaging characteristics in patients with cardiac amyloidosis. Methods: A total of 5 patients (4 males and 1 female) with the diagnosis of cardiac amyloidosis (3 were proven by heart transplantation, 2 by endomyocardial biopsy) were evaluated by electrocardiogram, echocardiogram, chest X-ray and CMR with delayed Gadolinium enhancement. Results: Echocardiograms were abnormal in all five patients; chest X- ray showed pulmonary hemorrhage (3), cardiomegaly (5), pleural effusion (3); echocardiogram showed atrial enlargement, left ventricular wall thickening, limited ventricular wall motion, etc. CMR exhibited increased thickness of the left ventricular wall, mild to moderate depression of systolic function (mean ejection fraction: 32.5%±15.0%) and bilateral atrial enlargement with restriction of diastolic ventricular filling. In all patients, there were widespread enhancement of the thickened myocardium on delayed post- contrast studies. In 4 patients, global subendocardial delayed gadolinium enhancement was found, in papillary muscles, and interventricular septa with 'zebra-like' sign in 3 patients. Left ventricular transmural delayed gadolinium enhancement was found in 1 patient. Conclusions: CMR shows a characteristic pattern of global subendocardial delayed gadolinium enhancement in cardiac amyloidosis. The findings may be valuable in the diagnosis of cardiac amyloidosis.

  12. Assessment of congenital heart disease (CHD): Is there a role for fetal magnetic resonance imaging (MRI)?

    International Nuclear Information System (INIS)

    Purpose: To review our experience with fetal magnetic resonance imaging (MRI) to evaluate congenital heart disease (CHD). Methods: We performed fetal MRI in 32 fetuses with an echocardiographically assessed CHD. Both direct and indirect signs of CHD were investigated. Direct signs considered were: morpho-volumetric abnormalities of the heart; malrotations; ventricular and atrial septal defects; anomalies of the origin, size and course of the great arteries. Indirect signs considered were: difficulty to recognize a 'normal' anatomical structures in the reference projections; increase of the vascular size before a stenosis; hypertrophy of the papillary muscles; cardiomegaly and pericardial effusion. All MRI findings were compared with postnatal or autoptic findings. Results: MRI allowed the CHD to be visualised by direct signs in 17 fetuses, indirect signs in 5 and both direct and indirect signs in 9 fetuses, excluding the prenatal echocardiographic suspect of hypoplastic left heart syndrome in 1 fetus. Postnatal echocardiograms or autoptic findings confirmed a normal heart in 1 fetus and CHD in 31 fetuses including a single cardiac anomaly or syndrome in 19 fetuses, 2 associated cardiac abnormalities in 11 and 3 cardiac anomalies in 1 fetus. However, in 2 fetuses MRI detected a ventricular septal defect successively disclosed by gold standard. Conclusions: MRI is a promising method for further assessment of the cardiovascular pathologies diagnosed by echocardiography, and may be a valuable tool in assessing associated extracardiac anomalies.

    8 cases of congenital coronary artery fistula of child age group, diagnosed by cineangiography and confirmed by operation at Seoul National University Hospital in recent 9 years were analysed. The summaries are as follows: 1. The overall incidence was 0.18% of those who underwent cardiac cineangiography (8/4460). 2. Age distribution was from 3 months to 14 years (mean was 5.6 years). Male to female was 4:4. 3. Important physical findings were continuous murmur (7/8) and ischemic change in EKG (3/8). 4. Chest X-ray findings were non-specific but mild cardiomegaly (6/7) and normal pulmonary vascularity (5/7). 5. In cinecardiography, origin of coronary artery fistula was right in 5 case, left in 1 case and single left coronary artery in 1 case. Draining sites were right atrium (3), right ventricle (2), pulmonary artery (1) and left ventricle (1). 6. Associated anomalies were single coronary artery in 1 case, ASD in 1 case and VSD in 1 case. 7. For accurate diagnosis of congenital coronary artery fistula, biplane cineangiography is an essential procedure (Root aortography or selective coronary angiography)

    Aortic dissection is a critical condition requiring immediate assessment and management. Clinical presentation is commonly associated with severe chest pain and high blood pressure. However, misdiagnosis is frequent because of various features. We presented a case of 51-year-old woman who complained of dyspnea for 3 d after she experienced back pain for one week. She was presented with severe respiration distress with impending respiration failure on arrival to our hospital. Her chest X-ray showed cardiomegaly with acute pulmonary edema. The laboratory data revealed elevated cardiac enzyme and electrocardiography demonstrated sinus tachycardia. She was hospitalized under the initial diagnosis of acute coronary syndrome. The patient remained hemodynamically stable, and experienced one episode of chest discomfort. After electrocardiography, she was found with bigeminy ventricular premature beats without ST-T change. Follow-up cardiac enzyme demonstrated progressive declined. Cardiac catheterization was performed on the third day of admission, and coronary angiography revealed large intimal flap on aortic root with bilateral coronary artery involvement. Surgical management was arranged after immediate chest computed tomography study.

  17. Primary intimal sarcoma of the pulmonary artery 1 case report and retrospective analysis of 20 cases published in China

    International Nuclear Information System (INIS)

    Objective: To explore the clinical and histopathological features of primary, intimal sarcoma of the pulmonary artery. Methods: One case of primary intimal sarcoma of the pulmonary artery diagnosed in our hospital and 20 cases published openly in China were analysed retrospectively. Results: The clinical presentation of primary intimal sarcoma of the pulmonary artery was progressive dyspnea, cough, chest pain, syncope, bloody phlegm, fever and fatigue. From the radiological finding, its signs were of pulmonary, artery dilation, reduced pulmonary vasculature and cardiomegaly, soft tissue mass near the right ventricle outflow tract. Histological examination of intimal sarcoma of the pulmonary artery revealed a poorly differentiated mesenchymal tumor of fibroblastic or myofibroblastic differentiation, consisting of mildly atypical spindle cells with atypia, mitosis, and nuclear polymorphism. Immunohistochemical analysis showed positive staining with antibodies against vimentin, alpha-smooth muscle actin, while negative for desmin. Conclusion: Primary, intimal sarcoma of the pulmonary artery has atypical clinical and radiological manifestation with poor prognosis, its definite diagnosis depends on histopathology. (authors)

  18. Radiographic and ultrasonographic features of hypertrophic feline muscular dystrophy in two cats

    International Nuclear Information System (INIS)

    Hypertrophic fellne musculer dystrophy has been reported as an X-linked inherited deficiency of a cytoskeletal myofiber protein called dystrophin. This report deserlbes the radiographic and ultrasonographic abnormalities of two male littermate domestic short-hair cats and reviews the previous reported findings assoclated with hypertrophic feline muscular dystrophy. The thoracic radiographic abnormalities included: progressive cardiomegaly, large convex, scalloped irregularities associated with the vetral aspect of the diaphragm, and variable degrees of esophageal dilation (megaesophagus) with associated cranioventral aspiration pneumonia. Echocardiographic features included: concentric left vetricular wall thickening, increased left ventricular and diastolic and systolic dimensions, and an increase in endocardial echogenicity. Abdominal radiographic abnormalities included: hepatosplenomegaly, peritoneal effusion, renomegaly, adrenal gland mineralization, and paralumbar and diaphragmatic musculature enlargement. Abdomlnal ultrasonographic abnormalities included: irregularly thickened muscular portion of the diaphragm; hypoechogenicity of the liver; peritoneal effusion; hepatosplenomegaly; renomegaly with hyperechoic cortex and medulla; and adrenal gland mineralization. The irregular scalloped appearance of the diaphragm (particularly along the ventral/sternal margin) was a consistenl radiographic abnormlity in the two cats with hypertrophic feline muscular dystrophy after the age of 7 months. This finding was confirmed by ultrasound as a thickened irregular, hyperechoic diaphragm. A diagnosis of hypertrophic feline muscular dystrophy should be strongly suspected if this abnormality is identified

    The radiologic changes of the chest X-ray of 270 newborns with respiratory distress were analyzed. In cases of Hyaline Membranes the chest X-Ray showed finely granular evenly disseminated structures combined with signs of hypoventilation. Localized, patchy, streaky, homogenous and reticulonodular shadows were found in cases of pneumonia and hemorrhage. Hyperinflation were an additional sign for an inflammatory disease. This symptom was also demonstrated in pulmonary bleeding, but was less common. The bilateral interstitial augmentation of the pulmonary structure in combination with cardiomegaly was mainly a symptom for cardial insufficiency and transient tachypnea. The differentiation between fine granular and reticulo-nodular structures should create no problem if the chest X-ray is of good quality. Extrapulmonary air collections were found in a high percentage in the course of artificial ventilation as a consequence of the 'baro-trauma'. The radiologic diagnosis of BPD was no problem. The value of the chest X-ray lies in the demonstration of a pulmonary cause for the respiratory distress, in the demonstration of complications and in the radiological observation of the disease.

    Uremic toxins accumulate in patients with chronic kidney diseases (CKDs) and cause further progression of renal damage and cardiovascular diseases. Recently, it was reported that some of the organic anion transporting polypeptides (OATPs) and the organic anion transporters (OATs) are involved in the renal elimination of uremic toxins. SLCO4C1 is the only OATP expressed at the basolateral side of proximal tubular cells in human kidney, and it mediates the excretion of uremic toxins. The overexpression of human SLCO4C1 in rat kidney promotes the renal excretion of uremic toxins and reduces hypertension, cardiomegaly, and renal inflammation in renal failure. Statins induce SLCO4C1 expression thorough transcriptional factor Aryl hydrocarbon receptor through binding of the xenobiotic responsive element at its promoter region. The administration of statin in a rat renal failure model facilitated the elimination of uremic toxins and mitigated organ damage. In addition, metabolomic analysis of rat renal failure models and patients with CKD by capillary electrophoresis-mass spectrometry is a useful method for identifying new uremic solutes and explores surrogate biomarkers for detecting the progression of early stage CKD.

    We here report an unusual case of Hb Bart's (γ4) disease. Thalassemia screening of a couple showed that the wife was an α(0)-thalassemia (α(0)-thal) carrier and her husband's mean corpuscular volume (MCV) was normal. Chorionic villus sampling (CVS) was performed at 13 weeks' gestation for positive Down syndrome screening and chromosomal study of the cultured CVS showed a normal karyotype. Ultrasound examination at 22 weeks' gestation showed fetal cardiomegaly and raised middle cerebral artery peak systolic velocity. Cordocentesis confirmed fetal anemia and showed Hb Bart's disease. Multiplex gap-polymerase chain reaction (gap-PCR) for α-thal deletions on DNA extracted from the CVS showed the presence of a homozygous α(0)-thal - -(SEA) (Southeast Asian) deletion. The husband was found to be a carrier of the α(+)-thal -α(3.7) (rightward) deletion. Non paternity was excluded by fluorescent PCR using short tandem repeat (STR) markers on chromosomes 13, 18 and 21. A de novo terminal deletion of chromosome 16 was excluded by array comparative genomic hybridization (aCGH). Detection of uniparental disomy (UPD), using STR markers on chromosome 16 showed maternal uniparental isodisomy from 16pter to 16p13.2, and uniparental heterodisomy from 16p13.13 to 16qter.

    An autopsy case of smoldering adult T-cell leukemia (ATL) is presented. 67 year-old woman was admitted to our hospital with complaints of fever, cough and increasing dyspnea on October 2, 1985. Laboratory findings revealed high LDH, azothermia and slightly leukocytosis with low percentage of flower cells. CRP was strongly positive. Gas disturbance was markedly. Anti-ATLA antibody using indirect immunofluorescence method was X40 positive. Subsets of peripheral lymphocytes showed OKT 4 dominant. (OKT 3; 67.5%, OKT4; 60.6%, OKT8; 8.8%). A chest X-ray film revealed cardiomegaly and fine granular shadows in bilateral lower pulmonary fields. Diagnosis of interstitial pneumonitis was defined in transbronchial lung biopsy (TBLB) specimen. O2 therapy, steroid therapy added antibiotics were ineffective, respiratory failure and renal failure were progressive, she died by septic shock in 39th hospital days. In autopsy, no characteristic histological changes of ATL were found in lymph node, bone marrow, spleen, liver, kidney and lung. Sepsis was the cause was of death. Finally this case diagnosed smoldering ATL and pulmonary fibrosis due to bronchial ectasia with repeated pulmonary bacterial infections. The pulmonary complications of patients with ATL were discussed. PMID:2886412

    A 38-day-old male warthog (Phacochoerus aethiopicus) with marked anaemia (haematocrit = 14 %) presented to the Denver Zoological Gardens hospital with ataxia, tachypnoea, suspected stunted growth and cardiomegaly. The piglet demonstrated some features consistent with both iron deficiency anaemia and autoimmune haemolytic anaemia. Serum-soluble iron was below the level of detection (< 8.96 micromol/l). Iron deficiency anaemia is a well recognised entity in domestic swine reared on concrete and denied access to soil. Fifteen captive warthogs were subsequently evaluated for serum soluble iron content (mean = 21.62 +/- 4.36 micromol/l as well as 5 neonatal warthog piglets that required hand-rearing. Only 1 of 5 neonatal warthog piglets had measurable serum soluble iron (9.50 micromol/l). These data suggest that warthogs are similar to domestic swine and are born with low iron stores. Some form of iron supplementation should be considered for captive neonatal warthog piglets, especially if they are reared on concrete. PMID:12515305

    Full Text Available Giant chorioangioma is a placental tumor associated with gestational complications such as preeclampsia, polyhydramnios and hemorrhage. In addition, this tumor might lead to the incidence of non-immune fetal hydrops, heart failure, anemia, thrombocytopenia, weight loss and death among neonates. In this case report, the clinical image of a term newborn (weighing 2800 g with one-minute Apgar score of 7 was suggestive of sepsis on the second day of birth. Moreover, epistaxis, petechia, anemia, thrombocytopenia, hypothermia, cardiomegaly and hepatosplenomegaly were detected in the neonate, which required blood transfusion and antibiotic therapy. However, in case of chorioangioma in the gestational history, it was possible to detect the motive for a clinical sepsis-like disease. According to the pathophysiological explanation, this tumor functions as a "dead space", increasing the rate of blood ejection with subsequent fetal heart failure, anemia through intratumoral hemorrhage or fetal-maternal transfusion, and consumption or intratumoral sequestration resulting in disseminated intravascular coagulation. After blood transfusion, all treatment procedures, including antibiotic therapy, were suspended due to the recovery of the newborn.

  6. Persistent release of IL-1s from skin is associated with systemic cardio-vascular disease, emaciation and systemic amyloidosis: the potential of anti-IL-1 therapy for systemic inflammatory diseases.

    Directory of Open Access Journals (Sweden)

    Keiichi Yamanaka

    Full Text Available The skin is an immune organ that contains innate and acquired immune systems and thus is able to respond to exogenous stimuli producing large amount of proinflammatory cytokines including IL-1 and IL-1 family members. The role of the epidermal IL-1 is not limited to initiation of local inflammatory responses, but also to induction of systemic inflammation. However, association of persistent release of IL-1 family members from severe skin inflammatory diseases such as psoriasis, epidermolysis bullosa, atopic dermatitis, blistering diseases and desmoglein-1 deficiency syndrome with diseases in systemic organs have not been so far assessed. Here, we showed the occurrence of severe systemic cardiovascular diseases and metabolic abnormalities including aberrant vascular wall remodeling with aortic stenosis, cardiomegaly, impaired limb and tail circulation, fatty tissue loss and systemic amyloid deposition in multiple organs with liver and kidney dysfunction in mouse models with severe dermatitis caused by persistent release of IL-1s from the skin. These morbid conditions were ameliorated by simultaneous administration of anti-IL-1α and IL-1β antibodies. These findings may explain the morbid association of arteriosclerosis, heart involvement, amyloidosis and cachexia in severe systemic skin diseases and systemic autoinflammatory diseases, and support the value of anti-IL-1 therapy for systemic inflammatory diseases.

    Purpose: To review our experience with fetal magnetic resonance imaging (MRI) to evaluate congenital heart disease (CHD). Methods: We performed fetal MRI in 32 fetuses with an echocardiographically assessed CHD. Both direct and indirect signs of CHD were investigated. Direct signs considered were: morpho-volumetric abnormalities of the heart; malrotations; ventricular and atrial septal defects; anomalies of the origin, size and course of the great arteries. Indirect signs considered were: difficulty to recognize a 'normal' anatomical structures in the reference projections; increase of the vascular size before a stenosis; hypertrophy of the papillary muscles; cardiomegaly and pericardial effusion. All MRI findings were compared with postnatal or autoptic findings. Results: MRI allowed the CHD to be visualised by direct signs in 17 fetuses, indirect signs in 5 and both direct and indirect signs in 9 fetuses, excluding the prenatal echocardiographic suspect of hypoplastic left heart syndrome in 1 fetus. Postnatal echocardiograms or autoptic findings confirmed a normal heart in 1 fetus and CHD in 31 fetuses including a single cardiac anomaly or syndrome in 19 fetuses, 2 associated cardiac abnormalities in 11 and 3 cardiac anomalies in 1 fetus. However, in 2 fetuses MRI detected a ventricular septal defect successively disclosed by gold standard. Conclusions: MRI is a promising method for further assessment of the cardiovascular pathologies diagnosed by echocardiography, and may be a valuable tool in assessing associated extracardiac anomalies.

    A novel avipoxvirus caused diphtheritic lesions in the oesophagus of five and in the bronchioli of four Magellanic penguins (Spheniscus magellanicus) and also cutaneous lesions in eight Magellanic penguins housed in outdoor enclosures in a Rehabilitation Centre at Florianópolis, Santa Catarina State, Brazil. At the same time, another avipoxvirus strain caused cutaneous lesions in three Magellanic penguins at a geographically distinct Rehabilitation Centre localized at Vila Velha, Espírito Santo State, Brazil. Diagnosis was based on clinical signs, histopathology and use of the polymerase chain reaction (PCR). Clinical signs in the penguins included cutaneous papules and nodules around eyelids and beaks, depression and restriction in weight gain. The most common gross lesions were severely congested and haemorrhagic lungs, splenomegaly and cardiomegaly. Histological examination revealed Bollinger inclusion bodies in cutaneous lesions, mild to severe bronchopneumonia, moderate periportal lymphocytic hepatitis, splenic lymphopenia and lymphocytolysis. Other frequent findings included necrotizing splenitis, enteritis, oesophagitis, dermatitis and airsacculitis. Cytoplasmic inclusion bodies were seen within oesophageal epithelial cells in five birds and in epithelial cells of the bronchioli in four penguins. DNA from all samples was amplified from skin tissue by PCR using P4b-targeting primers already described in the literature for avipoxvirus. The sequences showed two different virus strains belonging to the genus Avipoxvirus of the Chordopoxvirinae subfamily, one being divergent from the penguinpox and avipoxviruses already described in Magellanic penguins in Patagonia, but segregating within a clade of canarypox-like viruses implicated in diphtheritic and respiratory disease.

  9. Pulmonary manifestation of leptospirosis

    International Nuclear Information System (INIS)

    Authors analysed and present chest X-ray findings of serologically proven leptospirosis from Seoul National University Hospital, either admitted or referred for serological verification, during recent 2 years. Radiological findings were correlated with the lung specimen findings of experimentally induced leptospirosis in guinea pig. The results are as follows: 1. 24 cases (56%) showed positive X-ray findings. 2. Predominant radiological patterns of involved lung were tiny dot, small nodule, rosette density in 11 cases, massive confluent consolidation in 4 cases, and diffuse ill-defined velly increased density in 9 cases. 3. Distribution of pulmonary lesions were bilateral (100%), non-lobar, non-segmental (95%), and there were conspicuous tendency of peripheral lung predominance. 4. Extrapulmonary manifestation, such as pleural effusion or cardiomegaly was rate. 5. Pulmonary lesions resolved completely usually 5 to 10 days after their appearance. 6. From the gross and microscopic findings of serially sacrificed guinea pig's lung and a case of autopsy, authors concluded that fine dot-like density in chest X-ray was due to paleolithic hemorrhage in intraalveolar space at initial stage, growing up to ressette density or confluent consolidation as the pathetic extends to surrounding lung forming purpura and coalescent hemorrhage.

  10. Determination of the left ventricular volumina by computerized tomography, as compared to laevo-angiocardiography

    International Nuclear Information System (INIS)

    Cardiac CT, both prior to and after contrast medium injection, according to the current knowledge is a good and informative method of non-invasive volume measurements of the end-diastolic volume of the left ventricle, using the two-axial technique. The correlations made have shown that the evaluation model chosen will allow statistically satisfactory results to be obtained even by non-experienced analysts, and that it hence is a reliable and reproducible method. The evaluation employing planimetry consistently yields results exceeding those of cardiac catheterisation by up to 20 p.c. This difference is even higher in case of cardiomegaly or cardiac wall hypertrophy. The error sources inherent in this method still make end-systolic volume determination less satisfactory, although the results indicate possible ways of optimization. As the determination of stroke volume and output fraction is based on the end-systolic volume measurement, the error sources of this part of the method are taken into account in the evaluation. This explains the low linear correlation which, according to the current state of knowledge, would characterise the method as non-acceptable. Breaking down the case material into various groups of disease results in differently high correlations, due to the different configurations presented by the left ventricle as a consequence of various diseases. The best agreement is obtained in the group of patients suffering from cardiomyopathy. (orig./MG)

  11. Radiologic analysis of total anomalous pulmonary venous return;

    International Nuclear Information System (INIS)

    We reviewed cardiac cineangiographic and plain chest film findings of 48 patients aged from a half month to 14 years, with TAPVR which was documented by cineangiography. The numbers of supracardiac, cardiac, subdiapragmatic and mixed group were 20, 17, 3 and 8 in each. The frequency of the various types of TAPVR was: Left vertical vein, 15 pt's; right atrium, 11 pt's; Mixed, 8 pt's; coronary sinus, 6 pt's; subdiaphragmatic, 3 pt's; right SVC, 2 pt's etc. TAPVR occured without severe cardiac anomalies (isolated TAPVR) in 79%. In general, plain chest films revealed the tendency of pulmonary plethora, cardiomegaly and no evidence of congestion, but in the cases with stenosis of connecting vein showed the tendency of pulmonary congestion. Patients in whom the venous retum to left vertical vein or left SVC via right connecting vein and right innominate vein (mirror image of anomalous drainage to left vertical vein) showed a typical 'snowman' or unilateral superior mediastinal widening on the AP chest film (7 of 9 cases) and a density anterior to the trachea on the lateral film (3 of 9 cases). In a connection with azygos vein, the dilated azygos vein was recognized as an oval density in right tracheobronchial angle and right superior mediastinum was widened. Lateral chest film showed a posterior cardiac bulging shadow representing the dilated coronary sinus in 2 of 6 patients with anomalous drainage to the coronary sinus.

    Two captive agoutis (Dasyprocta mexicana) died of anemia with centrilobular hepatocellular necrosis (2/2), severe flea ectoparasitism (2/2), and cardiomegaly attributed to anemia (1/2). Other agoutis were similarly parasitized and one had anemia. Fleas were manually removed and all agoutis treated topically with propoxur and selamectin and moved to another enclosure. No additional cases of fatal anemia were seen. Cutaneous lesions suggestive of hypersensitivity were observed in three additional agoutis with dorsal alopecia (3/3), a penetrating wound associated with pruritus and self-mutilation in the flank (2/3), flea ectoparasitism at the time of morphologic diagnosis (1/3), and hyperplastic perivascular dermatitis (3/3). One of these died of bacterial infection of the wound. Similar but milder skin disease was seen in 3 out of over 30 maras (Dolichotis patagonum) housed in the same exhibit. Fleas collected from all the fatal agouti cases and maras were classified in the genus Echidnophaga based on the angular front margin of head, contracted thorax, absence of genal and pronotal combs, and the fact that fleas did not jump. These findings suggest that flea ectoparasitism may be an important cause of morbidity and mortality in captive rodents. PMID:18556127

    Certain drugs can induce ventricular tachycardia (VT) by creating reentry, ventricular after potentials or exaggerating the slope of phase 4. These may or may not be symptomatic, sustained or non-sustained and have variable ECG appearances: monomorphic or polymorphic, bidirectional, torsades de pointes. They risk degenerating into ventricular flutter of fibrillation and have been held responsible for the increased mortality observed unexpectedly in some long-term treatments. The drugs responsible are mainly those used in cardiology, probably due to predisposing circumstances (cardiomegaly, cardiac failure, previous severe ventricular arrhythmias, therapeutic associations, metabolic abnormalities). These include primarily the antiarrhythmic drugs (IA, IC, sotalol and bepridil), digitalis, sympathomimetics and phosphodiesterase inhibitors. These complications may be toxic or idiosyncratic, in patients with or without cardiac disease, and may also occur with other drugs: vasodilators and anti-anginal drugs (lidoflazine, vincamine, fenoxedil), psychotropic agents (phenothiazine and imipramine), antimitotics, antimalarials (chloroquine) or antibiotics (erythromycin, pentamidine). The prognosis is severe and the treatment is often difficult which makes prevention, helped by repeated surface ECG (or Holter monitoring), very important with careful assessment of patients at risk.

    We report a rare case of subclinical primary aldosteronism (PA) and subclinical Cushing's syndrome (CS). A 49-year-old woman was referred to our hospital for the evaluation of an adrenal incidentaloma. The patient had no previous medical history and no family history of notable illness. Her blood pressure was 103/60 mmHg. She had no Cushingoid features. Routine laboratory examinations were within the normal ranges including normokalemia. Based on the endocrinological results and imaging findings, we finally made a diagnosis of subclinical PA caused by both adrenal glands and subclinical CS caused by bilateral adrenal tumors. Interestingly, this patient had no risk factors for cardiovascular disease. In addition, the optimal management of patients with subclinical CS and subclinical PA has not been established. Therefore, we are observing her without medical therapy. Four years after diagnosis, no cardiovascular complications have been detected, including cerebral infarction, chronic kidney disease, cardiomegaly on echocardiography, and atherosclerosis on carotid ultrasonography. One important question is why the excessive hormone secretion did not affect the cardiovascular status of this patient. In this regard, we discuss several possible mechanisms including mineralocorticoid resistance and glucocorticoid sensitivity. PMID:27050894

    Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient''s high risk of strokes and hemorrhaging prompted investigation by a 99mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome

The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome.

    This paper reports four fatal cases of metastrongylid nematode Angiostrongylus dujardini infection observed in a Saguinus oedipus and a Callimico goeldii monkey and in two suricates (Suricata suricatta). All animals were kept in captivity in a zoo of central Italy. The two monkeys died with no premonitory signs, while the two-month-old suricates showed malaise, anorexia and tachypnea for a few days prior to death. Cardiomegaly and/or granulomatous pneumonia were the major anatomo-pathological findings. Inflammatory lesions were observed in the liver, heart and kidney of the suricates at histology. A. dujardini diagnosis was confirmed through both morphological identification of adult worms recovered at necropsy and molecular characterization of larvae in tissue samples. Callitrichidae and suricates are active predators and maintain their hunting behaviour in captivity and it is then likely that they were exposed to infection by preying on parasitized gastropods, intermediate hosts of A. dujardini, entering zoo enclosures from the surrounding environment. This is the first report of A. dujardini in Italy and in S. suricatta. PMID:27094227

    Trisomy 13 is a clinically severe entity; 85% of the patients do not survive beyond one year, and most children die before completing six months of age. We report a female child, 28 months old, white, the fourth child of a non-consanguineous couple, who presented trisomy 13. The child was born at term, from a vaginal delivery, weighing 2600 g. At birth, she was cyanotic, icteric, spastic, and cried weakly. The initial clinical examination detected polydactyly in the left hand, congenital clubfoot and convex soles, ocular hypertelorism, a low nasal bridge, numerous hemangiomas distributed throughout the body, cardiomegaly, and perimembranous inter-ventricular communication. There was no cleft lip or palate. On physical examination at 18 months old, the child weighed 6,900 g, had a cephalic perimeter of 41 cm, a thoracic perimeter of 43 cm and was 76 cm tall. At 28 months, she weighed 10,760 g and was 88.5 cm tall. Neuropsychomotor development retardation was evident from birth and, according to the psychologist and the social assistant of APAE (Handicapped Parents and Friends Association) in Canguçu, Rio Grande do Sul, there was a noticeable improvement after physiotherapy and recreational sessions.

    Full Text Available Background. Majority of dengue fever cases follow a benign self-limiting course but recently rare presentations and complications are increasingly seen due to rising burden of disease. Cardiac involvement in dengue fever with fatal outcome is a very rare complication. We report a case of 44-year-old patient who presented with symptoms of severe acute congestive heart secondary to myocarditis induced cardiomyopathy caused by dengue virus infection. Case Presentation. A 44-year-old man presented to ER with the complaints of high fever, fatigue, and shortness of breath. Patient was lethargic and blood pressure was low when he was brought to the ER. CXR showed cardiomegaly with pulmonary congestion and echocardiography revealed dilated left ventricle and ejection fraction of 10%. Patient condition worsened and he got admitted to the ICU because of acute hypoxic respiratory failure. Despite aggressive measures, patient died on day 5. Conclusion. Dilated cardiomyopathy is a rare complication of dengue myocarditis. Early recognition of acute DCM caused by dengue myocarditis is imperative in the management of dengue fever as early detection and management of cardiac failure can improve the survival of patient.

  1. Generation and use of sketches for chest X-ray image data base

    International Nuclear Information System (INIS)

    As the use of image processing technique extends into various fields, the realization of am image data base has been desired, which accumulates and manages images in large volume and takes the efficient retrieval and further the operative ability for processing into account. In this paper, the use of a kind of compressed images called ''sketch'' is proposed to do high grade retrieval based on image contents at high speed, and its usefulness is shown with the data base of actual chest X-ray images. The sketch must well express the main features of chest X-ray images (heart, ribs, blood vessels, forcuses, etc.) and minimize the quantity of data. The application of the developed sketch automatic extraction procedure to about 400 actual examples in the data base resulted in almost satisfactory extracted results. As an application of sketches, the retrieval using image pattern recognition technique and diagnostic results were recorded. In the experiment of extracting the cases of cardiomegaly out of 226 image sheets using the cardiothoracic ratio measured from the sketches, 11 sheets out of 14 true symptom cases were correctly retrieved to prove the usefulness of sketches to some extent. This data base of chest X-ray images is composed of an image input assembly which converts the directly and indirectly photographed images into digital density images of 3000 x 300 points, 8 bits per each point, and of five files, or master, control, header, temporary and sketch files.

    Full Text Available An 18-year-old boy was admitted with chest discomfort, nausea, and dyspnea at rest. At the age of 3 years, he underwent muscle biopsy and dystrophin gene analysis owing to an enlarged calf muscle and elevated serum kinase level (6,378 U/L without overt weakness; based on the results, Becker muscular dystrophy (BMD was diagnosed. The dystrophin gene showed deletion of exons 45 to 49. He remained ambulant and could step upstairs without significant difficulties. A chest roentgenogram showed cardiomegaly (cardiothoracic ratio, 54%, and his electrocardiogram (ECG showed abnormal ST-T wave, biatrial enlargement, and left ventricular hypertrophy. The 2-dimensional and M-mode ECGs showed a severely dilated left ventricular cavity with diffuse hypokinesis. The systolic indices were reduced, including fractional shortening (9% and ejection fraction (19%. Despite receiving intensive medical treatment, he died from congestive heart failure 5 months after the initial cardiac symptoms. We report a case of BMD with early-onset dilated cardiomyopathy associated with deletion of exons 45 to 49. Early cardiomyopathy can occur in BMD patients with certain genotypes; therefore, careful follow-up is required even in patients with mild phenotypes of BMD.

    Viral infections have been implicated as the cause of cardiomyopathy in several mammalian species. This study describes hypertrophic cardiomyopathy (HCM) and myocarditis associated with feline immunodeficiency virus (FIV) infection in five cats aged between 1 and 4 years. Clinical manifestations included dyspnoea in four animals, one of which also exhibited restlessness. One animal showed only lethargy, anorexia and vomiting. Necropsy examination revealed marked cardiomegaly, marked left ventricular hypertrophy and pallor of the myocardium and epicardium in all animals. Microscopical and immunohistochemical examination showed multifocal infiltration of the myocardium with T lymphocytes and fewer macrophages, neutrophils and plasma cells. An intense immunoreaction for FIV antigen in the cytoplasm and nucleus of lymphocytes and the cytoplasm of some macrophages was observed via immunohistochemistry (IHC). IHC did not reveal the presence of antigen from feline calicivirus, coronavirus, feline leukaemia virus, feline parvovirus, Chlamydia spp. or Toxoplasma gondii. The results demonstrate the occurrence of FIV infection in inflammatory cells in the myocardium of five cats with myocarditis and HCM. PMID:26797583

    Full Text Available Hypertrophic obstructive cardiomyopathy (HOCM is a rare disorder. There is paucity of literature on anaesthetic management of this disorder. Aim of this case report is to highlight the anaesthetic problems encountered during management of such patients. A thirty-five year old male was admitted with atypical chest pain for last one year. X-ray chest revealed cardiomegaly (CT ratio 0.6. Electrocardiographic findings were left axis deviation with left ventricular hypertrophy. On echocardiography, there was moderate mitral regurgitation (MR, systolic anterior motion (SAM of anterior mitral leaflet and prominent systolic narrowing of left ventricle cavity. Transoesophageal echocardiography (TOE also showed an anomalous muscle bundle stretching into LV causing obstruction. Preload was kept high. Systemic vascular resistance (SVR was maintained, avoiding use of vasodilators and inotropes. Morrow′s septal myectomy was done. Anomalous muscle bundle was excised. On postoperative TOE, there was no MR and no obstruction. Optimal anaesthetic management in such patients involves maintaining adequate preload, systemic vascular resistance and minimal outflow obstruction. Other considerations are to maintain haemodynamic stability, sinus rhythm and afterload. Transoesophageal echocardiography is an extremely useful monitoring device in such patients.

    Cardiac tamponade as an initial manifestation of undifferentiated connective tissue diseases (UCTD) is extremely rare, with only one case reported in literature thus far. We describe here, a case of a middle-aged man who presented with symptoms of fatigue, exertional dyspnea and orthopnea. His physical exam was significant for anasarca, elevated JVP and pulsus paradoxus. Chest X-ray showed pleural effusions and cardiomegaly, electrocardiogram revealed electrical alternans and a transthoracic echocardiogram demonstrated massive pericardial effusion with hemodynamic compromise. There was clear evidence of tamponade on right heart catheterization. All common causes of pericardial effusion were assiduously excluded before working up the patient for connective tissue disorders, which revealed a high antinuclear antibody titer (1:160), grossly elevated SSA, SSB antibodies and increased C-reactive protein levels (13.04 mg/dl). Patient had no signs or symptoms suggestive of systemic sclerosis (xerophthalmia or xerostomia) and did not meet criteria for any other known connective tissue diseases. He was therefore diagnosed with UCTD, and successfully treated with colchicine after emergency pericardiocentesis. This case presents UCTD as a rare cause of cardiac tamponade and large pericardial effusions and suggests that colchicine can be used to treat UCTD-associated effusions. These patients once diagnosed, are at risk of developing known connective tissue diseases within 5 years of disease onset and should be followed up in clinic periodically. PMID:20013265

    We report herein a case of benign cardiac schwannoma in the interatrial septum. A 42-year-old woman was transferred from a clinic because of cardiomegaly as determined by chest X-ray. A transthoracic echocardiography and chest computed tomography examination revealed a huge mass in the pericardium compressing the right atrium, superior vena cava (SVC), left atrium, and superior pulmonary vein. To confirm that the tumor originated from either heart or mediastinum, cine magnetic resonance imaging was performed, but the result was not conclusive. To facilitate surgical planning, we used 3D printing. Using a printed heart model, we decided that tumor resection under cardiopulmonary bypass (CPB) through sternotomy would be technically feasible. At surgery, a huge tumor in the interatrial septum was confirmed. By incision on the atrial roof between the aorta and SVC, tumor enucleation was performed successfully under CPB. Pathology revealed benign schwannoma. The patient was discharged without complication. 3D printing of the heart and tumor was found to be helpful when deciding optimal surgical approach.

    Full Text Available Cor-triatriatum is a rare congenital cardiac anomaly. It accounts for 0.1% of congenital heart diseases. Its association with multiple ventricular septal defects (VSD is even rarer. A five-month-old baby was admitted with respiratory distress and failure to thrive. Clinical examination revealed diastolic murmur over mitral area. Chest X-ray showed cardiomegaly. Haematological and biochemical investigations were within normal limits. Electrocardiogram showed left atrial enlargement. 2D echo showed double-chambered left atrium (cor-triatriatum, atrial septal defect (ASD and muscular VSD with moderate pulmonary arterial hypertension. The child was treated with 100% oxygen, diuretics and digoxin and was stabilized medically. We used balanced anaesthetic technique using oxygen, air, isoflurane, fentanyl, midazolam and vecuronium. Patient was operated under cardiopulmonary bypass (CPB with moderate hypothermia. Through right atriotomy abnormal membrane in the left atrium was excised to make one chamber. VSD were closed with Dacron patches and ASD was closed with autologous pericardial patch. Patient tolerated the whole procedure well and was ventilated electively for 12h in the intensive care unit. He was discharged on the 10 th postoperative day.

    Full Text Available A full-term female newborn with neonatal asphyxia and severe anemia (Hb 2.5 g/dL with normal heart developed a massive myocardial infarction. No examinations were performed during pregnancy for parental nomadism. The baby had immediate external cardiac massage, ventilatory assistance, and blood transfusion. Cardiomegaly was evident at chest X-ray and marked signs of ischemia-lesion at ECG. Echocardiography showed dilated, hypertrophic, and hypocontractile left ventricle (LV, mitral and tricuspid regurgitation, and moderate pericardial effusion. Rh isoimmunization and infective agents were excluded at laboratory tests. Despite the treatment with inotropes, hydrocortisone, and furosemide, the baby worsened and died at 45 hours of life. Postmortem examination showed diffuse subendocardial infarction of LV and diffuse parenchymal hemorrhages and myocardial hypertrophy, increase of eosinophilia, and polymorphonucleated cells at histology. Our patient suffered apparently from longstanding fetal anemia of unknown etiology that led to perinatal distress, severe hypoxia, and massive myocardial infarction, unresponsive to the therapy.

    Full Text Available INTRODUCTION: Polycystic Kidney Disease is a genetic disorder characterized by progressive cystic dilations of the renal ducts, presenting as autosomal dominant or recessive forms with an incidence of 1 in 1.000 and 1 in 20.000 births, respectively, according to international series. The autosomal recessive variety can be lethal in the neonatal period due to respiratory failure secondary to pulmonary hypoplasia and can manifest during childhood with hypertension, short stature and complications of portal hypertension. CASE REPORT: 3 years and 11 months old preschoolar with antecedent of fetal growth restriction and oligohydramnios during prenatal period, and a history of asthenia, pallor and progressive feeding difficulty with postprandial vomiting. Physical examination shows cardiac bruit, hypertension, splenomegaly, caput medusae and short stature. Laboratory tests with peripheral pancytopenia; abdominal ultrasonography showed hepatosplenomegaly, findings consistent with autosomal recessive polycystic kidney disease and periportal fibrosis; renal scintigraphy with bilateral kidney failure; a positive fecal occult blood test; an upper endoscopy that shows small esophageal varices; a hand radiography that shows bone age delayed and an echocardiography with cardiomegaly. DISCUSSION: This infrequent disease requires a high degree of suspicion by the clinician and presents with portal hypertension, with platelet count being the best predictor of severity. This condition has no cure and will progress to end-stage renal disease in any moment, so the aim is to minimize and treat renal and hepatic complications.

    Fourteen cases of double chambered right ventricle were diagnosed angiographically and of these nine cases were confirmed after operation and autopsy at Seoul National University Hospital in recent four years since 1979. The clinical and radiological findings with the emphasis on the cinecardiographic findings were analysed. The summaries of the analysis are as follows: 1. Among 14 cases, 6 cases were male and 8 cases were female. Age distribution was from 4 years to 36 years. 2. In chest x-ray findings, pulmonary vascularity was increased in 8 cases, decreased in 4 cases, and normal in 2 cases. Cardiomegaly was observed in 8 cases and other showed normal heart size. 3. In cinecardiography, 11 cases had interventricular septal defect. Among these 11 cases, VSD located in proximal high pressure chamber was in 2 cases and located in distal low pressure chamber was in 9 cases. 4. The location of aberrant muscle bundle in sinus portion of right ventricle was in 8 cases. In the rest 6 cases, the aberrant muscle bundle was located below the infundibulum of right ventricle. 5. For accurate diagnosis and differential diagnosis with other congenital cardiac anomalies such as Tetralogy of Fallot or isolated pulmonic stenosis, biplane cineangiography and catheterization is an essential procedure.

    The effect of anemia on the coronary microcirculation was studied in young male rats. Chronic anemia resulted in increased left ventricular end-diastolic pressure and decreased functional reserve. Cardiac mass in anemic animals increased by 25%. Capillary and arteriolar densities in these hearts remained unchanged, indicating angiogenesis in this experimental situation (estimated aggregate capillary length in the left ventricle of anemic hearts was 3.06 km compared with 2.35 km in control hearts). Capillary hematocrit was decreased in chronic anemia less than systemic hematocrit: from 25 to 18% in anemia versus 45 to 28% in controls. Capillary hematocrit and red blood cell spacing were also studied after acute blood withdrawal. Here, capillary hematocrit was preserved even more: 22 versus 24% in systemic hematocrit. Finally, the same was studied in isolated hearts perfused with solutions of various hematocrits. After perfusion with low-hematocrit solution (14%), the capillary hematocrit (24%) was even higher than the perfusate hematocrit! In conclusion, we found evidence of angiogenesis in cardiomegaly induced by chronic anemia. Microvascular growth was accompanied by advantageous regulation of red blood cell spacing within these vessels. This was even more pronounced during acute hemodilution and in isolated perfused hearts. PMID:11179091

    "Hypertensive" variant of congenital adrenal hyperplasia is rare. The authors describe an interesting case of a 6-y-old boy who presented with an acute respiratory illness and progressive breathlessness since 1 y. Genital hyperpigmentation was noticed since 2 y of age; the onset of pubarche and increasing penile size at 4 y. He was admitted in congestive cardiac failure with a blood pressure of 150/100 mm Hg. Facial acne; slight facial, pubic hair and penile enlargement were additionally noted. Chest radiograph revealed cardiomegaly. Basal ACTH and 17-OHP levels were high. A diagnosis of congenital adrenal hyperplasia (11β-hydroxylase deficiency) was made due to hypertension with virilized genitalia. Cardiac failure was controlled with fluid restriction and diuretics; he was started on prednisolone, spironolactone and nifedipine. This case is presented for its rarity where hypertension can cause complication of cardiac failure, if diagnosis is delayed despite early features of pseudoprecocious puberty. PMID:22231770

    Background The anomalous origin of the left coronary artery (LCA) from the pulmonary artery (ALCAPA) and congenital left main coronary artery atresia (CLMCA-A) are two kinds of very rare coronary heart diseases which affect heart function profoundly.This study aimed to retrospectively illustrate the clinical features and therapy experience of ALCAPA and CLMCA-A patients.Methods From April 1984 to July 2012,in Beijing Anzhen Hospital,23 patients were diagnosed with ALCAPA and 4 patients with CLMCA-A.We summarized the clinical data of the 27 cases and retrospectively analyzed the clinical manifestation,diagnosis,and treatments of these two kinds of congenital coronary abnormalities.Results The 23 patients (13 males and 10 females,aged ranging from 2.5 months to 65 years) identified with ALCAPA were classified into infantile type (age of onset younger than 12 months,16 cases) and adult type (age of onset older than 12 months,7 cases).Four patients were diagnosed with CLMCA-A (three males and one female,aged ranging from 3 months to 2 years).The main clinical manifestations of infantile-type ALCAPA and CLMCA-A include repeated respiratory tract infection,heart failure,dyspnea,feeding intolerance,diaphoresis,and failure to thrive.And these two congenital coronary abnormalities might be misdiagnosed as endocardial fibroelastosis,dilated cardiomyopathy,and acute myocardial infarction.As for the adult-type ALCAPA,cardiac murmurs and discomfort of the precordial area are the most common presentations and might be misdiagnosed as coronary heart disease,myocarditis,or patent ductus arteriosus.In ECG examination:Infantile-type ALCAPA and CLMCA-A showed abnormal Q waves with T wave inversion in leads I,avL,and V4-V6,especially in lead avL.However,ECG of adult-type ALCAPA lacked distinct features.In chest radiography:pulmonary congestion and cardiomegaly were the most common findings in infantile-type ALCAPA and CLMCA-A,while pulmonary artery segment dilation was more common in

  14. Thoracic radiographic features of anticoagulant rodenticide toxicity in fourteen dogs

    International Nuclear Information System (INIS)

    Thoracic radiographs and clinical records from 14 dogs with confirmed anticoagulant rodenticide toxicity were reviewed. Twelve of the 14 dogs were presented with a chief complaint of respiratory distress, and 12 had elevated prothrombin and activated partial thromboplastin times consistent with a coagulopathy secondary to a clotting factor deficiency. Thoracic radiographs of the 14 dogs were reviewed and abnomalities included increased mediastinal soft tissue opacity with extra and intrathoracic tracheal narrowing (4/14), increased mediastinal soft tissue opacity without tracheal narrowing (8/14), variable degrees of pleural effusion (13/14) and generalized, patchy interstitial/alveolar pulmonary infiltrates (8/14). Radiographic evidence of cardiomegaly and pulmonary artery abnormalities consistent with concurrent heartworm infestation were detected in one dog. In four dogs, dramatic tracheal narrowing was identified on the lateral thoracic radiograph caused by either mediastinal hemorrhage compressing the trachea or submucosal hemorrhage within the tracheal lumen. The trachea was displaced in a ventral direction in two dogs, and extra and intrathoracic luminal diameter narrowing was evident cranially in all four dogs. Two of these four dogs had soft tissue opacity within the dorsal trachea that extended from the larynx to the intrathoracic trachea. Twelve of the 14 dogs survived with standard treatment protocols utilizing injectable and oral vitamin K1. One dog died from pancreatitis and disseminated intravascular coagulopathy. The other dog died soon after presentation due to severe, disseminated hemorrhage. Follow-up thoracic radiographs were made in four dogs that survived and showed resolution of the mediastinal, pleural and pulmonary changes within one to five days after the initiation of vitamin K1 therapy

  15. Pulmonary embolism

    International Nuclear Information System (INIS)

    Pulmonary embolism is a common medical problem whose incidence is likely to increase in our aging population. Although it is life-threatening, effective therapy exists. The treatment is not, however, without significant complications. Thus, accurate diagnosis is important. Unfortunately, the clinical manifestations of pulmonary embolism are nonspecific. Furthermore, in many patients the symptoms of an acute embolism are superimposed on underlying chronic heart or lung disease. Thus, a high index of suspicion is needed to identify pulmonary emboli. Laboratory parameters, including arterial oxygen tensions and electrocardiography, are as nonspecific as the clinical signs. They may be more useful in excluding another process than in diagnosing pulmonary embolism. The first radiologic examination is the chest radiograph, but the clinical symptoms are frequently out of proportion to the findings on the chest films. Classic manifestations of pulmonary embolism on the chest radiograph include a wedge-shaped peripheral opacity and a segmental or lobar diminution in vascularity with prominent central arteries. However, these findings are not commonly seen and, even when present, are not specific. Even less specific findings include cardiomegaly, pulmonary infiltrate, elevation of a hemidiaphragm, and pleural effusion. Many patients with pulmonary embolism may have a normal chest radiograph. The chest radiograph is essential, however, for two purposes. First, it may identify another cause of the patient's symptoms, such as a rib fracture, dissecting aortic aneurysm, or pneumothorax. Second, a chest radiograph is essential to interpretation of the radionuclide V/Q scan. The perfusion scan accurately reflects the perfusion of the lung. However, a perfusion defect may result from a variety of etiologies. Any process such as vascular stenosis or compression by tumor may restrict blood flow. 84 references

    Arterial leiomyosarcomas account for up to 21% of vascular leiomyosarcomas, with 56% of arterial leiomyosarcomas occurring in the pulmonary artery. While isolated cases of primary pulmonary artery leiomyosarcoma document survival up to 36 months after treatment, these uncommon, aggressive tumors are highly lethal, with 1-year survival estimated at 20% from the onset of symptoms. We discuss a rare case of a pulmonary artery leiomyosarcoma that was originally diagnosed as a pulmonary embolism (PE). A 72-year-old Caucasian female was initially diagnosed with ‘saddle pulmonary embolism’ based on computerized tomographic angiography of the chest 2 months prior to admission and placed on anticoagulation. Dyspnea escalated, and serial computed tomography scans showed cardiomegaly with pulmonary emboli involving the right and left main pulmonary arteries with extension into the right and left upper and lower lobe branches. An echocardiogram on admission showed severe pulmonary hypertension with a pulmonary artery pressure of 82.9 mm Hg, and a severely enlarged right ventricle. Respiratory distress and multiorgan failure developed and, unfortunately, the patient expired. Autopsy showed a lobulated, yellow mass throughout the main pulmonary arteries measuring 13 cm in diameter. The mass extended into the parenchyma of the right upper lobe. On microscopy, the mass was consistent with a high-grade primary pulmonary artery leiomyosarcoma. Median survival of patients with primary pulmonary artery leiomyosarcoma without surgery is one and a half months, and mortality is usually due to right-sided heart failure. Pulmonary artery leiomyosarcoma is a rare but highly lethal disease commonly mistaken for PE. Thus, we recommend clinicians to suspect this malignancy when anticoagulation fails to relieve initial symptoms. In conclusion, early detection and suspicion of pulmonary artery leiomyosarcoma should be considered in patients refractory to anticoagulation, prompting initiation

  18. Chest radiography for predicting the cause of febrile illness among inpatients in Moshi, Tanzania

    International Nuclear Information System (INIS)

    Aim: To describe chest radiographic abnormalities and assess their usefulness for predicting causes of fever in a resource-limited setting. Materials and methods: Febrile patients were enrolled in Moshi, Tanzania, and chest radiographs were evaluated by radiologists in Tanzania and the United States. Radiologists were blinded to the results of extensive laboratory evaluations to determine the cause of fever. Results: Of 870 febrile patients, 515 (59.2%) had a chest radiograph available; including 268 (66.5%) of the adolescents and adults, the remainder were infants and children. One hundred and nineteen (44.4%) adults and 51 (20.6%) children were human immunodeficiency virus (HIV)-infected. Among adults, radiographic abnormalities were present in 139 (51.9%), including 77 (28.7%) with homogeneous and heterogeneous lung opacities, 26 (9.7%) with lung nodules, 25 (9.3%) with pleural effusion, 23 (8.6%) with cardiomegaly, and 13 (4.9%) with lymphadenopathy. Among children, radiographic abnormalities were present in 87 (35.2%), including 76 (30.8%) with homogeneous and heterogeneous lung opacities and six (2.4%) with lymphadenopathy. Among adolescents and adults, the presence of opacities was predictive of Streptococcus pneumoniae and Coxiella burnetii, whereas the presence of pulmonary nodules was predictive of Histoplasma capsulatum and Cryptococcus neoformans. Conclusions: Chest radiograph abnormalities among febrile inpatients are common in northern Tanzania. Chest radiography is a useful adjunct for establishing an aetiologic diagnosis of febrile illness and may provide useful information for patient management, in particular for pneumococcal disease, Q fever, and fungal infections

  19. Echocaridography, electrocardiography, and radiography of cats with dilatation cardiomyopathy, hypertrophic cardiomyopathy, and hyperyroidism

    International Nuclear Information System (INIS)

    The echocardiographic, ECG, and radiographic findings of sequentially examined cats with dilatation cardiomyopathy (DCM, n = 7), hypertrophic cardiomyopathy (HCM, n = 8), and hyperthyroidism (HT, n = 20) were compared with those of healthy control cats (n = 11). Cats with DCM were easily differentiated from healthy cats by echocardiography and from cats with HCM and HT by a dilated left ventricle at end-diastole with a mean +/- SD of 2.20 +/- 0.36 cm, reduced fractional shortening (2.9% +/- 3.7%), reduced aortic amplitude (0.07 +/- 0.05 cm), reduced left ventricular wall amplitude (0.09 +/- 0.09 cm), and increased E-point septal separation (0.83 +/- 0.29 cm). The cats with HCM were most consistently recognized echocardiographically by increased left ventricular wall thickness at end-diastole (0.75 +/- 0.12 cm). Some cats with HT had abnormal echocardiograms with left ventricular wall hypertrophy. These cats could usually be differentiated from the cats with HCM because of normal or increased ventricular wall amplitude, aortic amplitude, or percentage of thickening of the left ventricular wall and interventricular septum. Left atrial enlargement (left atrial diameter greater than 1.57 cm or left atrium/aorta greater than 1.75) was commonly detected by the echocardiogram in cats with DCM, HCM, or HT. The echocardiogram was helpful in differentiating the type of cardiomyopathy (DCM, HCM, or HT) when plain thoracic radiographs indicated that cardiomegaly existed. The ECG may have indicated incorrectly that there was left ventricular enlargement in some cats with HT, and it did not indicate consistently that left ventricular enlargement existed when present in cats with DCM or HCM. The ECG was a poor indicator of left atrial enlargement in all cats

    Full Text Available Introduction: Pulmonary embolism (PE is a common lethal disease that its clinical symptoms may be seen in many other diseases. Computed tomography pulmonary angiography (CTPA is a valuable diagnostic modality for detection of PE. In addition, it can accurately detect the other diseases with clinical symptoms similar to PE. The aim of this study is to evaluate the frequency of PE and nonembolic disease with similar clinical symptoms including pulmonary, pleural, mediastinal, and cardiovascular diseases that have been detected by CTPA and to describe the importance of reporting these CT findings. Materials and Methods: In this cross‐sectional study, we evaluated the medical records of CTPA in 300 patients of suspected PE between March 2012 and February 2013 in Imam Reza Hospital and Ghaem Hospital in Mashhad University of Medical Sciences, Mashhad, Iran. Demographic information and the results of CTPA of these patients were re‐evaluated. One radiologist reviewed all of the CTPA and the results have been analyzed by SPSS‐16 software. Results: In this study, PE was detected in 18.7% of patients. Multiple incidental imaging findings were diagnosed as follow: pulmonary consolidation (33.2%, pleural effusion (48.7%, pulmonary nodules (10%, pulmonary masses (1.3%, pneumothorax (4.7%, mediastinal mass and lymphadenopathy (9.3%, aortic calcification (42%, coronary arteries calcification (27.3%, mitral valve calcification (2 %, cardiomegaly (30.7%, and the evidences of right ventricular dysfunction (6.7%. Conclusion: A group of disease can cause the clinical symptoms similar to that of PE. Among them, pulmonary consolidation and pleural effusion have much higher frequency than PE. In addition, CTPA can show pathologic findings in the patients that need follow‐up. It is important to detect and report these imaging findings because some of them may change the treatment and prognosis of patient who are suspected to have PE.

  1. Swiss cheese ventricular septal defect with myocarditis - A rare coexistence in a neonate

    Full Text Available Myocarditis is defined as acute inflammation of the myocardium, usually following a non-specific flu-like illness, and encompasses a wide range of clinical presentations ranging from mild or subclinical disease to heart failure. We report a 12-day-old healthy full-term neonate who presented with abrupt onset of congestive cardiac failure (CCF following a viral prodrome. Examination revealed persistent sinus tachycardia, lymphocytosis, gross cardiomegaly, nonspecific electrocardiogram changes with echocardiography showing Swiss cheese ventricular septal defect (VSD. VSD alone very rarely presents as early-onset cardiac failure in the absence of other precipitating factors like anemia, sepsis, hypoglycemia etc. Myocarditis, however, can mimic VSD and can present as fulminant cardiac failure in an otherwise healthy newborn. Myocarditis is usually diagnosed based on circumstantial evidence such as a recent viral infection and the sudden onset of cardiac dysfunction while ruling out other diagnostic possibilities. Elevated troponin T level is one of the most crucial noninvasive diagnostic modalities. Several trials have concluded that levels >0.055 ng/ml are statistically significant for diagnosing myocarditis in children. In our case an abrupt onset of cardiac failure following a viral prodrome and markedly elevated cardiac troponin T without sepsis and in the presence of normal coronary anatomy clinched the diagnosis of myocarditis. An early and aggressive treatment for CCF along with regular long-term follow-up plays a key role in the management of myocarditis. Role of high-dose Intravenous immunoglobulin in myocarditis has been studied by many trials with different outcomes. This is the first case report showing coexistence of VSD with myocarditis in a neonate presenting as early-onset acute cardiac failure. The report highlights the importance of screening for myocarditis in all previously normal babies presenting primarily with cardiogenic

    Background and purpose. Abnormalities of the chest wall have been described in bronchopulmonary dysplasia (BPD). Clinical, radiographic and pulmonary function variables were evaluated in 1-year-old children ventilated because of neonatal lung disease in order to quantify these thoracic changes and to evaluate the lung disease. Methods. The pulmonary status of 51 infants with neonatal lung disease requiring artificial ventilation was reevaluated clinically and radiographically at the age of 1 year. Twenty-two of these infants had developed BPD. Thoracic depth and width were measured clinically and on chest X-ray. The Toce score evaluated the presence of cardiomegaly, hyperinflation, emphysema and interstitial lung disease. Lung function was measured after sedation using previously reported methods. In BPD patients, Toce score and lung function were determined and compared at 1 month and at 1 year of age. Results. In BPD patients, chest depth was significantly smaller when measured clinically as well as on chest radiograph (P < 0.05; Mann-Whitney U-test). There was a statistically significant correlation between chest depth measured clinically and on chest X-ray. Toce score was significantly higher in BPD patients (P < 0.05). In BPD patients intersitial abnormalities and decreased lung compliance were more frequent at the age of 1 month than at the age of 1 year. At the age of 1 year, hyperinflation was more frequent and at that time increased airway resistance was still noted. Thus the type of X-ray abnormality reflects the type of lung function disturbance. Conclusion. The flatness of the chest is most likely a consequence of the long-standing lung function abnormalities. (orig.). With 3 figs., 6 tabs.

  3. Chest radiographic appearances in adult inpatients admitted with swine flu infection: local experience in Melbourne

    International Nuclear Information System (INIS)

    The influenza A virus (H1N1) pandemic began in Mexico in March 2009. As of July 2009, there were 5298 reported cases in Australia including 10 deaths. The aim of this review is to demonstrate the local chest radiographic findings in adult inpatients with proven H1N1, to assess the radiological disease progression and resolution, and to evaluate whether the severity of chest X-rays findings had a bearing on the length of admission and need for intensive care admission. Eleven H1N1 patients (5 males and 6 females, mean age of 36), presenting with cough (64%), fever (55%) and shortness of breath (55%), were admitted to our hospital between 13 August and 1 November 2010. Details of radiographic features, risk factors, clinical course including length of stay, doubling time of consolidation and time for 50% resolution of consolidation were recorded and analysed. Seventy-three per cent of our patients presented with bilateral mid and/or lower zone alveolar consolidation. One patient with underlying cystic fibrosis had only bilateral upper zone consolidation. No pleural effusion, lymphadenopathy or cardiomegaly was noted on any of the plain chest radiographs. The mean doubling time of consolidation was 1.5 days. The mean time for 50% resolution of consolidation after antiviral treatment was 10.5 days. The average length of stay in hospital was 22 days. Ninety-one per cent of our patients required intensive-care unit admission with 50% of those requiring intubation. Rapid progression of bilateral mid and lower zone air-space opacities in relatively young unwell patients, with lack of pleural effusion, pericardial effusion or lymphadenopathy on plain radiographs, should raise the clinical suspicion of H1N1 infection. Patients requiring hospital admission usually show slow clinical and radiological improvement, and require prolonged hospital stays.

    CASE DESCRIPTION An adult sexually intact female Harris hawk (Parabuteo unicinctus) housed at a wildlife hospital was evaluated because of acute collapse during an educational exhibition. CLINICAL FINDINGS Physical examination and hematologic analysis revealed no abnormalities; radiography revealed findings consistent with a previous tibiotarsal fracture. Coelioscopy with histologic examination and fungal culture of lung and air sac samples revealed anthracosis but no fungal infection. The hawk was discharged and temporarily removed from the education program; 1 month later, upon reintroduction into the program, it collapsed again. Physical examination and hematologic findings were similar to those after the first episode. Transcoelomic and transesophageal echocardiography and CT angiocardiography findings were consistent with cardiomyopathy. TREATMENT AND OUTCOME Initial cardiac treatment included furosemide (0.5 mg/kg [0.23 mg/lb], PO, q 24 h) and pimobendan (10 mg/kg [4.5 mg/lb], PO, q 12 h). After 10 days of treatment, peak and trough plasma concentrations of pimobendan were measured at 25, 196 and 715.97 ng/mL, respectively; the dosage was decreased to 0.25 mg/kg (0.11 mg/lb), PO, every 12 hours. No overt signs of toxicosis were detected. A sample was collected to reevaluate plasma pimobendan concentration after 30 days of treatment; results were not obtained prior to the patient's death but revealed a peak concentration of 16.8 ng/mL, with an undetectable trough concentration. The hawk was found dead 6 months after initial evaluation. Necropsy revealed cardiomegaly, but histologic examination did not reveal an inciting cause of cardiac dysfunction. CLINICAL RELEVANCE Cardiac disease in raptors may be underreported. Transcoelomic and transesophageal echocardiography and CT angiography provided useful information for the diagnosis of cardiac disease in the hawk of this report. PMID:27379599

    Full Text Available Background: Cardiovascular abnormalities are among common complication in patients with cirrhosis waiting for liver transplantation (LT. The aim of the present study was to investigate cardiac abnormalities among pediatric liver transplant candidates.Methods: We prospectively evaluated the pediatric patient aged less than 18 years listed for LT between 2006 and 2008. Besides history taking and physical examination all the patients underwent electrocardiogram, chest radiograph, contrast echocardiography and color Doppler echocardiography, as well as arterial blood gas analyses.Results: Totally 89 patients with mean age of 8.1±4.6 years were included in the study. The most common causes for liver disease were cryptogenic cirrhosis followed by biliary atresia and autoimmune cirrhosis. Clubbing was found in 27 out of 89 patients and was the most common abnormalities in physical examination. In 22 patients (24.7% heart murmur was heard by a pediatric cardiologist. Sixty nine patients (77.5% had normal cardiac findings in chest radiograph. Cardiomegaly was found in 17 (19.1% patients as the most common abnormal finding in chest radiograph. Electrocardiogram showed sinus tachycardia in 16 (18% patients. Eleven patients (12.4% had tricuspid regurgitation as the most common abnormal findings in echocardiography. Thirteen (14.6% patients had positive contrast echocardiography in favor of intrapulmonary shunt.Conclusion: As the leading cause of post transplant death after graft rejection are cardiovascular complications cardiac evaluation should be considered in all pediatric patients before LT to lower morbidity and mortality during and after transplantation.

    Full Text Available There is controversy regarding the inclusion of patients with hypertension among cases of peripartum cardiomyopathy (PPCM, as the practice has contributed significantly to the discrepancy in reported characteristics of PPCM. We sought to determine whether hypertensive heart failure of pregnancy (HHFP (i.e., peripartum cardiac failure associated with any form of hypertension and PPCM have similar or different clinical features and outcome.We compared the time of onset of symptoms, clinical profile (including electrocardiographic [ECG] and echocardiographic features and outcome of patients with HHFP (n = 53; age 29.6 ± 6.6 years and PPCM (n = 30; age 31.5 ± 7.5 years. The onset of symptoms was postpartum in all PPCM patients, whereas it was antepartum in 85% of HHFP cases (p<0.001. PPCM was more significantly associated with the following features than HHFP (p<0.05: twin pregnancy, smoking, cardiomegaly with lower left ventricular ejection fraction on echocardiography, and longer QRS duration, QRS abnormalities, left atrial hypertrophy, left bundle branch block, T wave inversion and atrial fibrillation on ECG. By contrast, HHFP patients were significantly more likely (p<0.05 to have a family history of hypertension, hypertension and pre-eclampsia in a previous pregnancy, tachycardia at presentation on ECG, and left ventricular hypertrophy on echocardiography. Chronic heart failure, intra-cardiac thrombus and pulmonary hypertension were found significantly more commonly in PPCM than in HHFP (p<0.05. There were 5 deaths in the PPCM group compared to none among HHFP cases (p = 0.005 during follow-up.There are significant differences in the time of onset of heart failure, clinical, ECG and echocardiographic features, and outcome of HHFP compared to PPCM, indicating that the presence of hypertension in pregnancy-associated heart failure may not fit the case definition of idiopathic PPCM.

  7. When a pulmonary embolism is not a pulmonary embolism: a rare case of primary pulmonary leiomyosarcoma

    Full Text Available Arterial leiomyosarcomas account for up to 21% of vascular leiomyosarcomas, with 56% of arterial leiomyosarcomas occurring in the pulmonary artery. While isolated cases of primary pulmonary artery leiomyosarcoma document survival up to 36 months after treatment, these uncommon, aggressive tumors are highly lethal, with 1-year survival estimated at 20% from the onset of symptoms. We discuss a rare case of a pulmonary artery leiomyosarcoma that was originally diagnosed as a pulmonary embolism (PE. A 72-year-old Caucasian female was initially diagnosed with ‘saddle pulmonary embolism’ based on computerized tomographic angiography of the chest 2 months prior to admission and placed on anticoagulation. Dyspnea escalated, and serial computed tomography scans showed cardiomegaly with pulmonary emboli involving the right and left main pulmonary arteries with extension into the right and left upper and lower lobe branches. An echocardiogram on admission showed severe pulmonary hypertension with a pulmonary artery pressure of 82.9 mm Hg, and a severely enlarged right ventricle. Respiratory distress and multiorgan failure developed and, unfortunately, the patient expired. Autopsy showed a lobulated, yellow mass throughout the main pulmonary arteries measuring 13 cm in diameter. The mass extended into the parenchyma of the right upper lobe. On microscopy, the mass was consistent with a high-grade primary pulmonary artery leiomyosarcoma. Median survival of patients with primary pulmonary artery leiomyosarcoma without surgery is one and a half months, and mortality is usually due to right-sided heart failure. Pulmonary artery leiomyosarcoma is a rare but highly lethal disease commonly mistaken for PE. Thus, we recommend clinicians to suspect this malignancy when anticoagulation fails to relieve initial symptoms. In conclusion, early detection and suspicion of pulmonary artery leiomyosarcoma should be considered in patients refractory to anticoagulation

    Objectives To review all patients with SCO2 mutations and to describe a Brazilian patient with cardioencephalomyopathy carrying compound heterozygous mutations in SCO2, one being the known pathogenic p.E140K mutation and the other a novel 12–base pair (bp) deletion at nucleotides 1519 through 1530 (c.1519_1530del). Design Case report and literature review. Setting University hospital Patient Infant girl presenting with an encephalomyopathy, inspiratory stridor, ventilator failure, progressive hypotonia, and weakness, leading to death. Main Outcome Measures Clinical features, neuro-imaging findings, muscle biopsy with histochemical analysis, and genetic studies. Results This infant girl was the first child of healthy, nonconsanguineous parents. She developed progressive muscular hypotonia and ventilatory failure. At the end of the first month of life, she developed cardiomegaly and signs of cardiac failure. Routine blood tests showed lactic acidosis and mild elevation of the creatine kinase level. Brain magnetic resonance imaging showed increased T2 and fluid-attenuated inversion recovery signals in the putamen bilaterally. Nerve conduction studies showed severe axonal sensorimotor neuropathy. Muscle biopsy revealed a neurogenic pattern with mitochondrial proliferation and total absence of cytochrome-c oxidase histochemical stain. Sequencing of SCO2 showed that the patient had compound heterozygote SCO2 mutations: the previously described c.1541G A (p.E140K) mutation and a novel 12-bp deletion at nucleotides 1519 through 1530 (c.1519_1530del). The patient died at age 45 days. Conclusions Our findings and the literature review indicate that it is important to consider the diagnosis of mitochondrial disease in newborns with hypotonia and cardiomyopathy. In our case, the accurate diagnosis of SCO2 mutations is particularly important for genetic counseling. PMID:23407777

    2007-01-01

    Full Text Available An 8-week old 3-kilogram male baby was brought to this tertiary care hospital with respiratory distress, marked tracheal tug, poor feeding and a heart rate of 46/minute. The child had been referred from a peripheral hospital as a case of neonatal lupus with complete congenital heart block. The mother was seropositive for systemic lupus erythematosus with a history of two abortions. Evaluation on admission revealed a heart rate between 40-60/ minute, respiratory rate 40-50/ minute, inspiratory stridor, bilateral crepitations, chest retrac-tion and a marked tracheal tug that improved with prone positioning. Electrocardiography and echocardiography confirmed complete congenital heart block with cardiomegaly and mild left ventricular dysfunction. Keeping in view the impending congestive heart failure, possible early cardiomyopathy and the bad obstetric history ur-gent pacemaker implantation was planned to allow early recovery of the child. The anaesthetic risk was high due to the heart block, ventricular dysfunction, laryngomalacia, severe tracheal tug and anticipated difficult weaning from controlled ventilation. General anaesthesia was administered with endotracheal tube and con-trolled ventilation using ketamine, rocuronium and sufentanil. For patient safety invasive monitoring was pro-vided and external pacing was kept standby. Epicardial pacemaker leads were implanted onto the left ventricu-lar wall through a left anterior 6th intercostal space thoracotomy. The child was electively ventilated for two post operative days. The tracheal tug and secretions gradually subsided over 2 weeks with oxygen, antibiotics, steroids, bronchodilators and physiotherapy. At the time of discharge from hospital 2 weeks after the implant the child was feeding well, tracheal tug was minimal and the lungs were clear.

    Full Text Available Diagnosis of congenital cardiac defects is challenging, with some being diagnosed during pregnancy while others are diagnosed after birth or later on during childhood. Prompt diagnosis allows early intervention and best prognosis. Contemporary diagnosis relies upon the history, clinical examination, pulse oximetery, chest X-ray, electrocardiogram (ECG, echocardiography (ECHO, computed tomography (CT and cardiac catheterization. These diagnostic modalities reliable upon recording electrical activity or sound waves or upon radiation. Yet, congenital heart diseases are still liable to misdiagnosis because of level of operator expertise and other multiple factors. In an attempt to minimize effect of operator expertise this paper built a classification model for heart murmur recognition using Hidden Markov Model (HMM. This paper used Mel Frequency Cepestral coefficient (MFCC as a feature and 13 MFCC coefficients. The machine learning model built by studying 1069 different heart sounds covering normal heart sounds, ventricular septal defect (VSD, mitral regurgitation (MR, aortic stenosis (AS, aortic regurgitation (AR, patent ductus arteriosus (PDA, pulmonary regurgitation (PR, and pulmonary stenosis (PS. MFCC feature used to extract feature matrix for each type of heart sounds after separation according to amplitude threshold. The frequency of normal heart sound (range= 1Hz to 139Hz was specific without overlap with any of the studied defects (ranged= 156-556Hz. The frequency ranges for each of these defects was typical without overlap according to examined heart area (aortic, pulmonary, tricuspid and mitral area. The overall correct classification rate (CCR using this model was 96% and sensitivity 98%. This model has great potential for prompt screening and specific defect detection. Effect of cardiac contractility, cardiomegaly or cardiac electrical activity on this novel detection system needs to be verified in future works.

    International Nuclear Information System (INIS)

    Total 32 cases of pulmonary atresia were diagnosed radiographically at Seoul National University Hospital from March, 1979 to August 1982. Some characteristic radiological findings were analyzed in chest PA and cineangiographies. The results were as follows: 1. In the evaluation of chest PA, cardiomegaly was noticed in 16 cases, dextrocardia in 8 cases, elevated cardiac apex in 7 cases and right-sided aortic arch in 6 cases. The pulmonary vascularties were mildly decreased in 20 cases, markedly decreased in 9 cases and decreased with reticular pattern in 3 cases. 2. As final diagnoses after cineangiography, pulmonary atresia was associated with Tetralogy of Fallot variant in 17 cases, transposition of great vessels in 7 cases, single ventricle in 5 cases, tricuspid atresia in 2 cases and intact ventricular septum in 1 case. 3. The classification according to the pattern of pulmonary artery is main pulmonary trunk with PDA(Type Ia) in 10 cases, pulmonary arterial confluence with PDA (Type Ib) in 10 cases, no pulmonary arterial confluence with PDA (Type Ic) in 5 cases, main pulmonary trunk without PDA (Type IIa) in 0 case, pulmonary arterial confluence without PDA (Type IIb) in 5 cases, and no pulmonary arterial confluence without PDA ( Type IIc) in 2 cases. 4. Pulmonary wedge venography was done and successful in 8 cases. Among them, confluence between right and left pulmonary arteries was noticed in 5 cases. 5. Biventricular cineangiograpy and/or pulmonary wedge venography, if necessary, is essential for the accurate diagnosis of pulmonary atresia to demonstrate detailed anatomy of pulmonary artery

  13. Complications and co-morbidities in radiographs of patients in traditional bone setters’ homes in Ogwa, Edo State, Nigeria: a community-based study

    International Nuclear Information System (INIS)

    Background: Musculoskeletal injuries are common in developing countries, but access to high quality orthopedic care is not. Traditional bone setters (TBS) serve to fill the gap, but the nature and quality of their treatment are largely understudied. Traditional bone setting in Idunmunkpaghan clan of Ogwa community, Edo State, Nigeria, was founded by Odion Ekhimere between about 1680 and 1705. The TBS practice in this community is studied to find out the complications and co-morbidities associated with it. Methods: A prospective community-based study of the patients admitted in the traditional bone setters’ homes was done at Ogwa over a -2-year period by studying the admission and discharge radiographs of patients treated in the community and by interviewing the TBS and patients. Result: Ninety patients with radiographs of the lesion sites were followed up from admission to discharge at the TBS homes, comprising 53 males (53.89%) and 37 females (41.11%) with a male to female ratio of 1.4:1. Sixty five patients (72.2%) had fracture or dislocation. Forty four of the 65 patients (67.7%) with fracture/dislocation had complications including mal-union 31(70.4%), secondary osteoarthritis 8 (18.2%), non-reduction of dislocation 7 (11.9%), non-union 8 (18.2%), and others 12 (27.2%). Co-morbidities were identified in 15 patients (16.7%) and included severe osteoarthritis 7 (46.7%), diabetic foot ulcer 4 (26.7%), severe hypertension with cardiomegaly 4 (26.7%), metastatic carcinoma of the prostate 3 (20.0%), septic arthritis 2 (13.3%), pulmonary tuberculosis 1 (6.7%) and others 3 (20.0%). Conclusion: The practice of traditional bone setting is well established in Idunmunkpaghan clan in Ukpogo quarter of Ogwa. Education and training of the TBS is the key to reduction of complications and co-morbidities seen in their practices as they have high patronage and the patients have high regards for them and will continue to patronize them

    Full Text Available Cardiac resynchronization therapy (CRT has become an increasingly important therapeutic option for patients (pts to treat dyssynchrony associated moderate and severe heart failure. Few reports however, determined the beneficial effects of CRT in pediatrics and midterm outcome following this therapy. Our aim is to assess the mid-term outcomes of CRT in children with evidence of dyssynchrony associated heart failure. Cardiac resynchronization therapy is beneficial in treating congenital heart disease patients who have evidence of dyssynchrony associated heart failure. Retrospective review of 18 consecutive pediatric patients who underwent CRT at our institution between January 2002 and August 2011 Cardiac resynchronization pacemaker was implanted in 18 pts the majority of pts (14 with congenital heart disease. Fourteen pts had preexisting complete heart block and chronic right ventricular pacing. Epicardial left ventricular leads were implanted in all pts while the atrial and right ventricular leads approach varied according to the pt size and anatomy. Indication for CRT was symptomatic dilated cardiomyopathy with evidence of electrical and/or mechanical dyssynchrony demonstrated by M-mode, 3-D echo, or tissue Doppler. The median age of this cohort was 14 years (range 6 months–16 years, the median follow-up time was 7.2 years (range 1–10 years. Subjectively, 16 out of 18 pts reported symptomatic improvement with decreased hospitalizations. The left ventricular ejection fraction improved from mean of 27% (SD 13% to mean of 50% (SD 13% (P value <0.001. Additionally, cardiomegaly improved significantly in during follow up (P value <0.001. The QRS duration with CRT was less but the change is not significant (P value = 0.1 suggesting that electrical resynchronization is not a prerequisite for clinical improvement in this cohort.

    Full Text Available BACKGROUND: Mice with a deficiency in the HDL receptor SR-BI and low expression of a modified apolipoprotein E gene (SR-BI KO/ApoeR61(h/h called 'HypoE' when fed an atherogenic, 'Paigen' diet develop occlusive, atherosclerotic coronary arterial disease (CHD, myocardial infarctions (MI, and heart dysfunction and die prematurely (50% mortality ~40 days after initiation of this diet. Because few murine models share with HypoE mice these cardinal, human-like, features of CHD, HypoE mice represent a novel, small animal, diet-inducible and genetically tractable model for CHD. To better describe the properties of this model, we have explored the effects of varying the composition and timing of administration of atherogenic diets, as well as social isolation vs. group housing, on these animals. METHODOLOGY/PRINCIPAL FINDINGS: HypoE mice were maintained on a standard lab chow diet (control until two months of age. Subsequently they received one of three atherogenic diets (Paigen, Paigen without cholate, Western or control diet for varying times and were housed in groups or singly, and we determined the plasma cholesterol levels, extent of cardiomegaly and/or survival. The rate of disease progression could be reduced by lowering the severity of the atherogenic diet and accelerated by social isolation. Disease could be induced by Paigen diets either containing or free of cholate. We also established conditions under which CHD could be initiated by an atherogenic diet and then subsequently, by replacing this diet with standard lab chow, hypercholesterolemia could be reduced and progression to early death prevented. CONCLUSIONS/SIGNIFICANCE: HypoE mice provide a powerful, surgery-free, diet-'titratable' small animal model that can be used to study the onset of recovery from occlusive, atherosclerotic CHD and heart failure due to MI. HypoE mice can be used for the analysis of the effects of environment (diet, social isolation on a variety of features of

    Ezetimibe (Zetia(®), Ezetrol(®), Merck, Whitehouse Station, NJ) is a potent inhibitor of sterol absorption, which selectively blocks the uptake of biliary and dietary cholesterol in the small intestine. Clinical trials have demonstrated the beneficial effects of ezetimibe on the reduction of atherogenic lipoproteins and the attainment of guideline-recommended lipid levels. Direct evidence that these improvements translate to a reduction in atherosclerosis or cardiovascular events is limited, although reductions in major atherosclerotic events that are consistent with the LDL-C lowering achieved have recently been presented for patients with chronic kidney disease treated with ezetimibe/simvastatin 10/20mg in the SHARP trial. Animal models of atherosclerosis have played a central role in defining the mechanisms involved in initiation and development of disease and have been used in drug development to evaluate potential therapeutic efficacy. The effect of ezetimibe on atherosclerosis has been examined in several of these animal model systems. ApoE knockout mice develop severe hypercholesterolemia and premature atherosclerosis with features similar to that seen in humans and techniques ranging from gross visualization of plaque to high-resolution MRI have demonstrated the consistent ability of ezetimibe to significantly inhibit atherosclerosis. sr-b1(-/-)/apoE(-/-) double knockout mice exhibit additional characteristics common to human coronary heart disease (CHD), and the one study of ezetimibe in sr-b1(-/-)/apoE(-/-) mice showed a significant reduction in aortic sinus plaque (57%), coronary arterial occlusion (68%), myocardial fibrosis (57%), and cardiomegaly (12%) compared with untreated controls. The effects of ezetimibe have also been evaluated in ldlr(-/-)/apoE(-/-) double knockout mice, demonstrating that functional LDL receptors were not required for ezetimibe-mediated reduction of plasma cholesterol or atherosclerosis. For the few studies that have been

The diagnose performed by the occurrence of bradi- takhikardia episode and the clinical symptoms, could be syncope, palpitation, or maybe asymptomatic. Some of the literature defined that the perioperative management of sick sinus syndrome is preoperative insertion of pacemaker (transcutaneal or transvenous pacing. A 75 years old man underwent laparotomy with diffuse peritonitis caused by gastric perforation. In preoperative clinical evaluation the patients revealed full awake ( compos mentis, with history of uncontrolled hypertension. In physical exammination a severe bradicardia was found with pulse of 31x/minute, and the blood pressure was 190/100 mmHg. In this rural hospital there was no fascility to insert the pace-maker.

    Obstructed total anomalous pulmonary venous connection (TAPVC) is frequently misdiagnosed as pulmonary disease and without operative correction early death is common. It is important to make a correct diagnosis before surgery. The purpose of this study was to describe the chest radiographic features of obstructed TAPVC and compare CT angiography with transthoracic echocardiography in the evaluation of obstructed TAPVC. Eighteen children with obstructed TAPVC were assessed. Their clinical and imaging data were retrospectively reviewed. The characteristic radiographic findings were analyzed and compared with surgical results, and the diagnostic accuracy of CT angiography and transthoracic echocardiography was evaluated in terms of pulmonary venous drainage and obstruction detection. The common radiographic features included pulmonary venous congestion or edema or both (16 of 18 cases, 89%), and absence of cardiomegaly (12 of 18 cases, 67%). CT angiography correctly diagnosed TAPVC and clearly revealed the draining sites in all children (five with supracardiac TAPVC, three with cardiac TAPVC, eight with infracardiac TAPVC and two with mixed TAPVC). The diagnostic agreement between CT angiography and surgery was 100%. Transthoracic echocardiography only correctly revealed the draining sites in 11 children (5 with supracardiac TAPVC, 2 with cardiac TAPVC and 4 with infracardiac TAPVC). The diagnostic agreement between transthoracic echocardiography and surgery was 61%. The diagnostic accuracy of CT angiography was higher than that of transthoracic echocardiography (P = 0.0156). Thirty-four sites of obstruction were correctly detected by CT angiography (11 in the mediastinum, 1 at the diaphragmatic level, 9 below the diaphragm and 13 stenotic individual pulmonary veins in the lung). The diagnostic agreement between CT angiography and surgery was 92%. Transthoracic echocardiography only correctly detected 15 sites of obstruction (11 in the mediastinum, 1 at the

    Background: Musculoskeletal injuries are common in developing countries, but access to high quality orthopedic care is not. Traditional bone setters (TBS) serve to fill the gap, but the nature and quality of their treatment are largely understudied. Traditional bone setting in Idunmunkpaghan clan of Ogwa community, Edo State, Nigeria, was founded by Odion Ekhimere between about 1680 and 1705. The TBS practice in this community is studied to find out the complications and co-morbidities associated with it. Methods: A prospective community-based study of the patients admitted in the traditional bone setters’ homes was done at Ogwa over a -2-year period by studying the admission and discharge radiographs of patients treated in the community and by interviewing the TBS and patients. Result: Ninety patients with radiographs of the lesion sites were followed up from admission to discharge at the TBS homes, comprising 53 males (53.89%) and 37 females (41.11%) with a male to female ratio of 1.4:1. Sixty five patients (72.2%) had fracture or dislocation. Forty four of the 65 patients (67.7%) with fracture/dislocation had complications including mal-union 31(70.4%), secondary osteoarthritis 8 (18.2%), non-reduction of dislocation 7 (11.9%), non-union 8 (18.2%), and others 12 (27.2%). Co-morbidities were identified in 15 patients (16.7%) and included severe osteoarthritis 7 (46.7%), diabetic foot ulcer 4 (26.7%), severe hypertension with cardiomegaly 4 (26.7%), metastatic carcinoma of the prostate 3 (20.0%), septic arthritis 2 (13.3%), pulmonary tuberculosis 1 (6.7%) and others 3 (20.0%). Conclusion: The practice of traditional bone setting is well established in Idunmunkpaghan clan in Ukpogo quarter of Ogwa. Education and training of the TBS is the key to reduction of complications and co-morbidities seen in their practices as they have high patronage and the patients have high regards for them and will continue to patronize them.

    Full Text Available A 25-year-old young male patient presented in casualty department with severe respiratory distress on the fourth day from onset of symptoms. The patient was nonsmoker and had no antecedent medical or drug history. Prior to admission, patient had dry cough and bilateral pleuritic chest pain for the last three days. He was in severe respiratory distress with use of accessory muscles of respiration. On examination, he had heart rate of 120 beats/min, blood pressure (BP of 150/80, respiratory rate of 48-52/min and central cyanosis present. On systemic examination, reduced intensity of breath sounds with extensive rhonchi and crepitation was found in both lung fields, with other examination being within normal limits. On pulse oximetry, oxygen saturation was 28% on room air, which increased up to 36% with the help of 4 L oxygen via nasal prongs. PaO 2 /FiO 2 ratio was 100. Chest X-ray analysis was suggestive of non-cardiac pulmonary edema in view of bilateral fluffy opacity without cardiomegaly. In view of 2/3 positive criteria, his provisional diagnosis was Acute Respiratory Distress Syndrome (ARDS. He required mechanical ventilatory support and was gradually weaned over a period of 10 days. The patient was treated with broad spectrum antibiotics and other supportive measures. On re-evaluation of history, we found that he was a goldsmith by occupation, smelting silver and gold for the past 8-10 years. On the day of onset of symptoms, while smelting silver he was exposed to golden yellow fumes for around 15 minutes, with the quantum of exposure more than any other day earlier. From previous experience and analysis of similar silver metals, he was able to tell us that the silver was adulterated with large amount of cadmium on that day than before. Serum level of cadmium was 2.9 μg/L 6 days after initial exposure. At the time of discharge, he had residual opacities in the chest radiograph and resting oxygen saturation was 94% on room air.

    Full Text Available Background & objectives: Recently, vivax malaria is also presenting as severe malaria causing multiorgan dysfunction similar to falciparum malaria. The present study was undertaken to evaluate the involvement of cardiovascular system in severe malaria. Methods: This is a clinical prospective study conducted on the cases of severe malaria in S.P. Medical College and PBM Hospital, Bikaner, India. In total, 100 cases (45 males, 55 females; age range 13-75 yr of severe malaria (P. vivax 60; P. falciparum 28; and mixed 12 diagnosed by peripheral blood smear examination, rapid card test and PCR were studied. Evaluation of cardiovascular system was done by clinical examination, chest Xray, ECG, high resolution transthoracic echocardiography and estimation of cardiac markers. Results: In all, 17% cases (9 P. falciparum, 5 P. vivax and 3 mixed were found to be suffering from cardiovascular involvement (11% circulatory failure, 7% congestive cardiac failure and 2% pulmonary edema. ECG showed sinus tachycardia in all the 17 patients, one had atrial ectopic and eight had non-specific ST-T changes. Cardiomegaly was seen in eight cases and pulmonary edema in two on X-ray chest. Echocardiography was within normal range but cardiac dimensions were increased in all the 17 cases. Troponin-I and CPK-MB were increased in 14 cases. Cardiovascular involvement in P. falciparum and mixed infection was associated with high parasite density but P. vivax infection was associated with relatively low parasite density. Involvement of cardiovascular system was associated with increased hospital stay (7.67 ± 2.23 vs 6.59 ± 0.87 days; p <0.001 and high mortality (5 died out of 17 patients. Significant ECG changes and cardiac markers indicate myocardial involvement in severe malaria. Interpretation & Conclusion: The present study indicates involvement of cardiovascular system in severe malaria as evidenced by changes in ECG and cardiac markers (Trop 1 and CPK-MB. The present

Apenas os búfalos dosados com 2,5 (1 dia e 1 mg/kg (7 dias de monensina não morreram. Os sinais clínicos iniciaram cerca de 6 h após dosagem com monensina e incluíram apatia, anorexia, diarréia, sialorréia, fraqueza muscular, taquicardia, dificuldade locomotora, dispnéia, distensão da jugular, decúbito e morte. As dosagens de creatinina quinase (CK dos búfalos aumentaram acentuadamente após dosagem com monensina. As alterações macroscópicas foram ascite, hidrotórax, hidropericárdio, cardiomegalia, hepatomegalia e áreas pálidas focais no miocárdio e nos músculos esqueléticos. Degeneração e necrose de miofibras foram os principais achados histopatológicos. Por outro lado, nenhuma evidência de doença, nem mesmo alteração nos níveis de CK, foram observados nos bovinos dosados com as mesmas dosagens de monensina, confirmando observações preliminares que esses animais são mais resistentes à monensina que os búfalos.Monensin is widely used as a feed additive to improve performance of livestock; however accidental poisoning by this ionophore compound has been reported in a number of animal species.

METHOD: From 1981 to 2000, 99 patients ranging in ages from one day to 13 years (4.1 ± 3.6 and median = 3 years underwent permanent transfemoral pacemaker implantation due to congenital (39.4%, postsurgical (54.5%, or non-surgically acquired bradycardia (6.1%. RESULTS: By the end of 7.1 ± 5.3 years (708.3 patient-years of prospective follow-up, 18 (18.2% patients had died. The actuarial survival rates were 85%, 79.5%, and 74.2%, at 5, 10, and 15 years, respectively. Independent predictors of mortality identified by Cox proportional hazards analysis were younger age at implantation (p = 0.028, the presence of untreated cardiac anomalies or intracardiac prostheses (p = 0.0001, and radiographic evidence of cardiomegaly (p = 0.035. CONCLUSIONS: Permanent endocardial pacing via the femoral vein presented survival expectance comparable to other techniques with a low rate of pacing complications. Long-term survival was limited by lower ages and cardiac dilatation at the time of implantation as well as by the presence of untreated cardiac defects or valve prostheses.

The frequency of spontaneous abortion was higher in chagasic women. Chronic chagasic cardiopathy, estimated to occur in 20.2% of the patients, showed 7.5% cardiomegaly, 6.2% aneurysm of the left ventricle, and with a predominance of dyspnea, palpitations and arterial hypertension. Xenodiagnosis was positive for 26.1% of the chagasics and the PCR was positive for 53.7%, and was significantly higher in males and alloctones. An analysis of the results shows that Chagas' disease, in the group studied, presented clinical and parasitologic characteristics demonstrating significant regional differences.

    AIM: To study the alterations of myocardial taurine transport function, taurine transporter (TAUT), and cysteinesulfinate decarboxylase (CSD) mRNA as well as effect of exogenous taurine in rats with isoproterenol (ISO)-induced cardiomegaly. METHODS: [3H]-Taurine uptake and release on myocardium were determined. Bindingsites of [3H]-taurine for myocardial sarcolemma were measured. TAUT and CSD mRNA levels were assayed usingcompetitive quantitative reverse transcription polymerase chain reaction (RT-PCR). RESULTS: ISO group ascompared with control group, myocardial taurine uptake markedly reduced, taurine release obviously increased;Bmax value of [3H]-taurine binding on cardiac sarcolemma reduced by 42 % (P<0.05); TAUT and CSD mRNA levelsdecreased by 40 % and 38 % (P<0.05), respectively. ISO+taurine group as compared with ISO-treated group, theamounts of taurine uptake and TAUT mRNA returned to normal; taurine release reduced; Bmax increased by 92 %(P<0.01), and CSD mRNA content augmented by 23 % (P<0.05). There were no statistical differences of Kdvalues among the four groups (P>0.05). CONCLUSION: The data indicate that the failure to generate sufficientTAUT on myocardial sarcolemma may be the fundamental abnormality in ISO-induced cardiac injury. The mecha-nism by which administration of murine considerably improves ISO-induced cardiac damage is probably to increasethe expression of TAUT gene and recover taurine transport function.%目的:观察异丙肾上腺素(ISO)导致心肌损伤大鼠的心肌组织牛磺酸跨膜转运功能及牛磺酸转运体(TAUT)和半胱氨酸亚磺酸脱羧酶(CSD)的改变.方法:用[3H]标记的牛磺酸测定心肌牛磺酸转运及其与心肌浆膜结合功能;竞争性RT-PCR测定TAUT和CSD mRNA的含量.结果:ISO组与对照组比,心肌[3H]-牛磺酸摄入减少,释放量增加,心肌浆膜最大结合速率(Bmax)减少,TAUT和CSD mRNA水平减少.牛磺酸治疗组与ISO组比,心肌牛磺酸摄入量明显增

    Background Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart anomaly. We aimed to illustrate the clinical features and long-term prognosis of patients with ALCAPA.Methods Twenty three patients (13 males and 10 females, ages ranging from 2.5 months to 65 years) identified as ALCAPA in Beijing Anzhen Hospital from April 1984 to June 2009 were divided into two groups, based on the age of onset: group 1 (≤12 months, n=16) and group 2 (>12 months, n=7).Results Fifty six point three percent of patients in group 1 had been misdiagnosed as endocardial fibroelastosis (9/16),18.8% as dilated cardiomyopathy (3/16) and 6.3% as myocardial infarction (1/16). Patients in group 2 were usually diagnosed as coronary heart disease, myocarditis, or patent ductus arteriosus. Electrocardiography in group 1 revealed abnormal Q waves with T wave inversion in leads I, avL, V4-V6, especially in lead avL (deep and wide Q wave); but no specific manifestations in group 2. A higher percentage of patients in group 1 had cardiomegaly on chest radiograph (86.7% vs. 33.3%, P=0.031), while pulmonary artery protrusion was more common in group 2 (26.7% vs. 83.3%,P=0.046). Lower left ventricular ejection fraction (LVEF) was present in group 1 than in group 2 ((48.5±11.5)% vs.(65.0±6.1)%, P <0.001). Apical ventricular aneurysm (62.5% vs. 0%, P=0.007), enhanced echogenicity of papillary muscles (87.5% vs. 28.6%, P=0.011) and endocardial thickening (93.8% vs. 14.3%, P <0.001) were more frequent in group 1 than in group 2. The ratio of the proximal right coronary artery (RCA) diameter to the aortic root diameter exceeded 0.14 in all cases, more prominent in group 2 (0.26±0.05 vs. 0.33±0.03, P=0.009). Increased coronary artery collaterals within the interventricular septum were detected in 18 patients (78.3%) by Doppler imaging. Twenty one patients underwent cardiac surgery, including left coronary artery (LCA) ligation (1/21), LCA

Group I consisted of 30 patients in the acute phase of the disease. Twenty two patients took an insufficient dose. Only 8 patients used the drug for 120 days in an initial daity dose of 15 mg/kilogram body weight for up to 2 weeks and later in a daily dose of 10 mg/kilo body weight. In 4 patients (50% the xenodiagnosis became negativa after treatment and in 3 the Machado Guerreiro test became negative. One patient died with acute cardiac failure on the 5th day of treatment. Six patients developed evidence of sensory peripheral neuritis while on treatment. Group II consisted of 15 outpatients in the chronic phase. They also took the drug for 120 days in a variable dosage of 5-15 mg/kilo body weight. They had at least one xenodiagnosis performedafter treatment in four patients xenodiagnosis became negative. The treatment had no effect on the electrocardiogram, degree of cardiomegaly, or appearance on barium swallow. Treatment did not prevent one patient from developing an arrhythmia and another cardiac failure. Group III also contained 15 patients in the chronic phase with positive xenodiagnosis treated with 10 mg/kilo body weight for 120 days. Twelve serial monthly xenodiagnosis were done after treatment using 80 T. infestans (10 to a box for each examination. In only 28.5% of the patients were all these xenodiagnoses negative. The frequency of parasitemia was decreased in the other patients but not eradicated. The number of xenodiagnoses positive before treatment was 43% and afterwards 24.4%. The number of positive boxes diminished from 29.6% to 7%. Group IV consisted of 17

Materials and methods: This is a prospective, descriptive and analytic study of 70 patients (3 to 13 years referred to the Cardiology Clinic of the Hospital Nacional de Niños, during a one year period. Every patient had a clinical history, a physical exam, a chest x-ray and ECG and an echocardiogram taken. Results: Only 62 patients completed all their evaluating tests, 3 4 (54.5% boys and 28 (45.2% girls. The mean age was 8.5 years and the median was 9 years. In 21% of the cases the chest x-ray was abnormal (6 showed bronchopneumonia, 2 air trapping, 2 pulmonary artery enlargement, 2 prominent hila and 2 cardiomegaly. The ECG was normal in 97%, the Echocardiogram was abnormal in 4 (1 showed and ASD, 1 a patent ductus arteriosus, 1 a dysplastic pulmonic valve and 1 a pericardial effusion. Stress tests and Holters were normal. Only 4.8% of the patients had heart disease. Conclusion: Consultation for chest pain in the pediatric age is frequent. History and physical examination are very important for the diagnosis and handling of these children. Chest pain though is infrequently associated with cardiac anomalies during childhood years and the patients with heart conditions and chest pain had other findings such as bradychardia, pericardial rub and murmurs.
