    Full Text Available A 15-month-old girl, born to the consanguineous parents, was referred with the sign of massive splenomegaly associated with thrombocytopenia and anemia. Plasma Chitotriosidase estimation was carried out as a screening test and was found to be normal with reduced activity of β-glucosidase in leucocytes suggestive of Gaucher disease. At the age of 4 years, severe osteoporosis and cardiomegaly with pulmonary congestion were observed in the child. Molecular analysis for GBA gene has revealed homozygous status for L444P (c.1448C in the proband, whereas parents and two elder sisters were found to be heterozygote. Prenatal study during the fourth pregnancy was carried out from cultured chorionic villi for β-glucosidase, which was in the carrier range. Further confirmation of the carrier status was carried out from amniotic fluid DNA and was found to be heterozygous for L444P (c.1448C in the GBA gene. This case demonstrates that children with the sign of splenomegaly with anemia and thrombocytopenia need to be screened for Gaucher disease, and molecular study can further help to confirm the heterozygous status, where prenatal study by enzyme investigation demonstrate heterozygous condition.

    Full Text Available Para analisar as repercussões da cardiomegalia sobre a função pulmonar em indivíduos adultos com insuficiência cardíaca (IC crônica, foram revisados artigos nas bases PUBMED, BIREME, ISI Web of Knowledge e COCHRANE, publicados na última década, estudos observacionais e sem restrição de idioma. Utilizados os descritores "cardiomegaly" e "Respiratory Function Tests", e negada a palavra "exercise". Foram incluídos artigos com IC crônica, de ambos os sexos, entre 19 e 64 anos, incluindo IC congestiva e cardiomiopatia dilatada e excluídos com IC aguda, com avaliações pós-intervenção clínica ou por exercício. Para avaliar a qualidade dos artigos foi utilizada a escala da Agency for Healthcare Research and Quality (AHRQ e aceitos aqueles com escore>50 pontos (0-100. Foram selecionados cinco artigos do total de 1093 e agrupados por parâmetros relacionados aos fluxos e volumes pulmonares, padrão ventilatório e desempenho muscular. Na AHRQ, dois estudos ficaram na faixa de 50-75% e os demais >75%. Eles apontam para redução da capacidade vital inspiratória (CVI, volume expiratório forçado no 1º segundo (VEF1 e pressão inspiratória máxima (PImáx em função da cardiomegalia, com discreta redução na relação VEF1/CVI e na capacidade de difusão para monóxido de carbono (DLCO. Portanto, segundo os estudos, a cardiomegalia leva a um padrão respiratório restritivo, com redução do volume alveolar que interfere na DLCO. As correlações mais fortes envolvem a redução da PImáx, CVI e VEF1.To analyze the repercussions of the cardiomegaly on lung function in adults with chronic heart failure (CHF, the databases PUBMED, BIREME, ISI Web of Knowledge and COCHRANE were considered to review observational studies published in the last decade without language restriction.

    Full Text Available Presentamos un nuevo procedimiento que determina de forma automática y fiable la presencia de cardiomegalia en radiografías torácicas. El CTR muestra la relación entre el tamaño del corazón y el tamaño del tórax. El esquema propuesto utiliza un clasificador robusto difuso para encontrar los valores correctos del tamaño del tórax y los límites del corazón derecho e izquierdo para medir el agrandamiento del corazón para detectar cardiomegalia. El método propuesto utiliza operaciones clásicas de morfología para segmentar los pulmones proporcionando baja complejidad computacional y el método difuso propuesto es robusto para encontrar las medidas correctas del CTR proporcionando un cálculo rápido porque las reglas difusas usan operaciones aritméticas elementales para desempeñar una buena detección de cardiomegalia. Finalmente, se mejoran los resultados de clasificación del método difuso propuesto utilizando una red neuronal función de base radial (RBF en términos de precisión, sensibilidad y especificidad.

    The effects of low energy laser radiation on the descendants of irradiated rats were investigated by comparing natimortality and the frequency of congenital malformations in three experimental and a control group. Natimortality was not significantly different among the groups. However, cardiomegaly, anophtalmia, dilated abdominal viscera, and premature closures of cranial sutures were recorded only in the experimental groups. (author)

    The cardiomyopathy associated with Adriamycin is frequently fatal and full clinical recovery is uncommon. To evaluate the radiological manifestation and the outcome of Adriamycin induced cardiac toxicity, we retrospectively reviewed the serial chest X-ray films of children treated with Adriamycin. Among 154 children with leukemia, fourteen patients developed clinical and radiologic evidence of congestive heart failure (CHF). Six out of 14 (43%) died of CHF within 2 weeks after attack and eight children survived after their acute episodes of CHF, were controlled following digoxin and diuretic therapy. Despite the improving clinical evidence of heart failure, the follow-up chest roentgenograms of these 8 children showed definite cardiomegaly as compared with the pre-treatment chest X-ray. Three children among 8 had minimal cardiomegaly and the remaining five children showed persistent, marked cardiomegaly during the period of 9-25 months of follow up. In summary, when CHF develops during chemotherapy in leukemic children, the possibility of Adriamycin induced cardiac toxicity should be suspected. Our findings showed that persistence of cardiomegaly represented significant cardiomyopathy despite clinical improvement of CHF

    Congenital tricuspid valve disease (Ebstein's anomaly, tricuspid valve dysplasia) with severe tricuspid regurgitation and cardiomegaly is associated with poor prognosis. Fetal echocardiography can accurately measure right atrial enlargement, which is associated with a poor prognosis in the fetus with tricuspid valve disease. Fetal lung volumetric assessments have been used in an attempt to predict viability of fetuses using ultrasonogram and prenatal MRI. We describe a fetus with tricuspid dysplasia, severe tricuspid regurgitation, right atrial enlargement and markedly reduced lung volumes. The early gestational onset of cardiomegaly with bilateral lung compression raised the possibility of severe lung hypoplasia with decreased broncho-alveolar development. Use of fetal echocardiography with measurement of pulmonary artery size combined with prenatal MRI scanning of lung volumes resulted in an improved understanding of this anomaly and directed the management strategy towards a successful Fontan circulation. 2010 S.

    Echocardiographic aspects of chronic mitral valvular disease were studied and compared to physical, radiographic and electrocardiographic aspects. Seventy dogs were used, and clinical examination, thoracic radiography, electrocardiogram and echocardiogram were performed. Correlations between regurgitation severity with cardiac failure functional class and murmur intensity were observed. The electrocardiogram showed a low sensibility in detecting cardiac chamber enlargement, caused by mitral regurgitation. All the dogs with severe mitral regurgitation showed cardiomegaly according to thoracic radiographies

    We experienced a case of transient right-sided heart failure after angioplasty of membranous obstruction of the inferior vena cava confirmed by sonography and an inferior vena cavogram. Angioplasty involved the use of a self-expandable metallic stent, but after successful recanalization of the obstruction, the patient became dyspneic. Chest radiography revealed mild cardiomegaly with pulmonary congestion, but this was resolved spontaneously. For the prevention of serious heart failure, we recommend preprocedural evaluation of cardiac function. (author)

    To identify the incidence of clinically significant findings on preoperative thoracic radiographs in dogs with gastric dilatation-volvulus (GDV) and to determine if those findings are associated with survival. Retrospective study from 2000 to 2010. Urban university small animal teaching hospital. One hundred and one dogs diagnosed with GDV that had thoracic radiographs obtained preoperatively, and medical records available with the following information available: signalment, time of presentation, respiratory status, plasma lactate, presence of cardiac arrhythmias, reason for thoracic radiographs, radiographic findings, and outcome. None. Findings on preoperative thoracic radiographs included small vena cava (40%), esophageal dilation (39%), microcardia (34%), aspiration pneumonia (14%), cardiomegaly (5%), pulmonary nodule (4%), pulmonary edema (2%), sternal lymphadenopathy (1%), and pulmonary bullae (1%). Eighty-four percent of dogs (85 out of 101) survived to discharge. Dogs without cardiomegaly on presenting thoracic radiographs had a 10.2 greater odds of surviving to discharge. The most common findings on preoperative thoracic radiographs include esophageal dilation, microcardia, and a small vena cava while the incidence of pulmonary nodules was low. A negative association between survival and presence of cardiomegaly on preoperative thoracic radiographs in dogs with GDV supports the need to obtain these images for prognostic information in spite of the emergency surgical nature of the GDV. The main limitations of this study include the possibilities of type I and type II errors, the retrospective nature of the study, and the lack of well-defined criteria for obtaining thoracic radiographs. © Veterinary Emergency and Critical Care Society 2012.

    Full Text Available Cardiovascular disorders are common in HIV-1 infected persons in Africa and presentation is often insidious. Development of screening algorithms for cardiovascular disorders appropriate to a resource-constrained setting could facilitate timely referral. Cardiothoracic ratio (CTR on chest radiograph (CXR has been suggested as a potential screening tool but little is known about its reproducibility and stability. Our primary aim was to evaluate the stability and the inter-observer variability of CTR in HIV-1 infected outpatients. We further evaluated the prevalence of cardiomegaly (CTR≥0.5 and its relationship with other risk factors in this population.HIV-1 infected participants were identified during screening for a tuberculosis vaccine trial in Khayelitsha, South Africa between August 2011 and April 2012. Participants had a digital posterior-anterior CXR performed as well as history, examination and baseline observations. CXRs were viewed using OsiriX software and CTR calculated using digital callipers.450 HIV-1-infected adults were evaluated, median age 34 years (IQR 30-40 with a CD4 count 566/mm3 (IQR 443-724, 70% on antiretroviral therapy (ART. The prevalence of cardiomegaly was 12.7% (95% C.I. 9.6%-15.8%. CTR was calculated by a 2nd reader for 113 participants, measurements were highly correlated r = 0.95 (95% C.I. 0.93-0.97 and agreement of cardiomegaly substantial κ = 0.78 (95% C.I 0.61-0.95. CXR were repeated in 51 participants at 4-12 weeks, CTR measurements between the 2 time points were highly correlated r = 0.77 (95% C.I 0.68-0.88 and agreement of cardiomegaly excellent κ = 0.92 (95% C.I. 0.77-1.

    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

    Male, 0 FINAL DIAGNOSIS: Bland-White-Garland syndrome Symptoms: Cardiomegaly, feeding problems Medication: - Clinical Procedure: Reimplantation of the left coronary artery to the aorta Specialty: Pediatrics and Neonatology. Rare disease. Bland-White-Garland syndrome (BWGS) is a very rare disease characterized by anomalous origin of the left coronary artery from the pulmonary trunk (ALCAPA). WBGS affects 1 in every 300 000 live births. Children typically present with dyspnea, pallor, and failure to thrive. Without surgical repair, most of these children die during the first months of life. This case report describes 3-month-old boy admitted to the hospital because of feeding problems. The boy was born at term, with birth weight 3200 g, and was 10 points in Apgar score. He was breast-fed from birth. From the seventh week of age, his mother observed his increasing difficulties with feeding. Physical examination revealed pale skin, diminished heart sounds, tachycardia, cardiomegaly, and hepatomegaly. Results of urine and blood tests and ultrasonography of the central nervous system and abdomen were normal. The chest radiography showed cardiomegaly and electrocardiogram revealed anterolateral myocardial infarction. On echocardiography, an anomalous left coronary artery arising from the pulmonary artery was found. The life-saving treatment of choice was immediate surgical reimplantation of the left coronary artery to the aorta. Children with congenital heart disease are often prone to malnutrition, but in rare cases failure to thrive and breast-feeding problems can be the first symptoms of life-threatening diseases like myocardial infarction secondary to Bland-White-Garland syndrome (BWGS).

    2007-06-15

    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 {approx} 39 (9.7%), age 40 {approx} 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 {approx} 49 group, age 35 {approx} 39 group, and age 50 or older group represented the case of CP angle blunting, pulmonary nodule, and cardiomegaly/tortuous aorta, respectively.

    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.

The most frequent radiographic parenchymal abnormality was multiple bilateral nodules

    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

    While rarely seen in the present-day Western world, phocomelia is not uncommon in underdeveloped countries. Phocomelia is an abnormality in which the limbs are not fully formed. It may be inherited as an autosomal recessive or dominant disorder. This case concerns a 12-year-old Afghan boy with multiple skeletal anomalies, most prominently of his right arm, including aplasia of the entire proximal humerus, hypoplasia of the clavicle and scapula, and absence of the radial ray and thumb. A hypoplastic left thumb was also present. Other anomalies included thoracic scoliosis, upper thoracic hemivertebrae, and mild cardiomegaly. The differential diagnosis and likely diagnosis are discussed.

    Left anterior, lateral, and posterior views on 50 consecutive /sup 99m/Tc-sulfur colloid lung scans were examined. Normal patients had continuity of activity between the left lung and the spleen on all three views. Patients with subphrenic abscess or large left pleural effusions showed no continuity between lung and spleen activity on any view, while other abnormalities, most commonly cardiomegaly, accounted for lack of lung-spleen continuity on the anterior view only. It is suggested that in all combined /sup 99m/Tc-sulfur colloid lung studies, the left side be examined as well as the right for abnormalities adjacent to the left diaphragm. (auth)

    Full Text Available A two-year-old girl with congenital dyserythropoietic anemia (CDA acutely developed fever, tachypnea, and increased oxygen requirement. Chest X-ray revealed bilateral interstitial infiltrates and mild cardiomegaly. Blood cultures grew no infectious agents, while pulmonary specimens grew cytomegalovirus (CMV. Treatment with intravenous ganciclovir was initiated but without response. Final cytologic preparations of bronchoalveolar lavage (BAL fluid revealed eosinophilic amorphous material consistent with pulmonary alveolar proteinosis (PAP. CDA and PAP are extremely rare disorders in pediatrics. PAP should be considered in patients with hematological disorders who present with acute interstitial pneumonia, after infectious causes are ruled out.

    Full Text Available Idiopathic aneurysmal dilatations of the right atrium are rare anomalies. We report one such case of a young man presenting with fatigue, abdominal distension, pedal oedema, unremarkable cardiac examination except for raised jugular venous pressure, an electrocardiogram showing normal sinus rhythm with right bundle-branch block, and an radiograph of the chest showing cardiomegaly. The echocardiographic examination revealed a giant right atrium with low pressure tricuspid regurgitation. The computed tomography confirmed the findings of two-dimensional echocardiography. He was put on medical treatment and remained symptomatically controlled on follow-up.

    A three-year-old spayed domestic short-haired cat presented for evaluation of weight loss, cardiomegaly and pleural effusion. Echocardiographic examination demonstrated a thickened pericardium with mild pericardial effusion and a large volume of pleural effusion characterized by exudate. Although the cat was treated with antibiotics, the clinical symptoms did not improve. The cat developed dyspnea and died on day 7. Necropsy revealed a large amount of modified transudates ascites, pleural effusion and markedly dilated pericardium. Histopathological examination revealed severe exudation of fibrin and granulation tissue in a thick layer of the epicardium. The cat was diagnosed with fibrinous pericarditis secondary to bacterial infection.

    Recent literature on chemoradiotherapy for esophageal cancer report the comparable survival results as surgery, and suggest the importance of management for the late adverse effect of chemoradiotherapy. The aim of this study is to investigate the incidence and risk factors of cardiomegaly after chemoradiotherapy using low dose continuous infusion of 5FU/CDDP+5FU for esophageal cancer. Fifty-one patients with stage I-IVA esophageal cancer who were treated by radiotherapy with more than 50 Gy with or without chemotherapy and followed up for more than 6 months were analyzed. Sixteen patients were treated by radiation alone and 35 patients were treated by chemoradiotherapy. A change of CTR (cardio-thoracic ratio) was defined as the difference between CTR in the pre-treatment X-ray film and CTR in the post-treatment X-ray film with maximum cardiac silhouette. A change of CTR by more than 10% was defined as ''significant cardiomegaly''. In this study cardiac area-dose'', which is the sum of the products of cardiac area within every radiation field and its target dose, was calculated in each patient as a radiation parameter. Significant cardiomegaly was noted in 1 patient (6%) in the radiation alone group, in 8 patients (23%) in the chemoradiotherapy group and in 9 patients (18%) in the total population. In cases with more than 0.4 m{sup 2}{center_dot}Gy in cardiac area-dose, CTR elevation was significantly higher than in cases with less than 0.4m{sup 2}{center_dot}Gy. More than moderate pleural effusion was noted in 5 patients (10%). Chronic pericardial effusion and subsequent cardiac tamponade was considered to be one of the contributing factors for pleural effusion, because increases of pleural effusion coincided with CTR elevations in 3 cases. In addition, the fact that no case had right-sided unilateral pleural effusion suggested the direct effect of radiation to the pleura. Significant cardiomegaly was seen in 18% of 51 patients with

    Cardiac involvement in Beckwith-Wiedemann syndrome is mostly limited to mild cardiomegaly. Although these patients have visceromegaly, macroglossia, gigantism, and adrenal cytomegaly, no significant myocardial changes have been described. An infant with dysmorphic features of this syndrome had supraventricular tachycardia since birth. Nodular lesions were present in the right atrium. Morphologically these lesions were composed of hypertrophic myocardial fibers admixed with multinucleated giant cells of myogenic origin. The exact nature of these lesions remains undetermined. It is postulated that hypertrophic myocardial cells may represent cardiac cytomegaly as a manifestation of the accelerated growth potential of cells seen with this syndrome.

    Tracheomalacia is an unfrequent disease that causes tracheal collapse during breathing. It is generally associated to esophageal atresia, but cases of primary tracheomalacia and others secondary to extrinsic compression, have also been described. Spontaneous resolution is generally the rule and only a few cases need surgical treatment. When this therapy fails or is not indicated for any reason, endoluminal tracheobronchial stents may be used. We have treated two patients with four expandable metallic stents: one had severe tracheomalacia associated to esophageal atresia and the other tracheobronchomalacia secondary to cardiomegaly. Results have been good in both cases.

    The patient was a 26 year-old man who was referred to our hospital in June 2011 because of severe heart failure. At age 24 years, he was found to have Becker muscular dystrophy. He received enalapril for cardiac dysfunction; however, he had worsening heart failure and was thus referred to our hospital. Echocardiography showed enlargement of the left ventricle, with a diastolic dimension of 77 mm and ejection fraction of 19%. His condition improved temporarily after an infusion of dobutamine and milrinone. He was then administered amiodarone for ventricular tachycardia; however, he subsequently developed hemoptysis. Amiodarone was discontinued and corticosteroid pulse therapy was administered followed by oral prednisolone (PSL). His creatinine phosphokinase (CPK) level and cardiomegaly improved after the corticosteroid therapy. The PSL dose was reduced gradually, bisoprolol was introduced, and the catecholamine infusion was tapered. A cardiac resynchronization device was implanted; however, the patient's condition gradually worsened, which necessitated dobutamine infusion for heart failure. We readministered 30 mg PSL, which decreased the CPK level and improved the cardiomegaly. The dobutamine infusion was discontinued, and the patient was discharged. He was given 7.5 mg PSL as an outpatient, and he returned to normal life without exacerbation of the heart failure. There are similar reports showing that corticosteroids are effective for skeletal muscle improvement in Duchenne muscular dystrophy; however, their effectiveness for heart failure has been rarely reported. We experienced a case of Becker muscular dystrophy in which corticosteroid therapy was effective for refractory heart failure.

    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.

    Cardiothoracic ratio (CTR), the ratio of cardiac diameter (CD) to thoracic diameter (TD), is a useful screening method to detect cardiomegaly, but is reliable only on posteroanterior chest radiography (chest PA). We performed this cross-sectional 3-phase study to establish reliable CTR from anteroposterior chest radiography (chest AP). First, CDChest PA/CDChest AP ratios were determined at different radiation distances by manipulating chest computed tomography to simulate chest PA and AP. CDChest PA was inferred from multiplying CDChest AP by this ratio. Incorporating this CD and substituting the most recent TDChest PA, we calculated the 'corrected' CTR and compared it with the conventional one in patients who took both the chest radiographies. Finally, its validity was investigated among the critically ill patients who performed portable chest AP. CDChest PA/CDChest AP ratio was {0.00099 × (radiation distance [cm])} + 0.79 (n = 61, r = 1.00, P chest AP with an available previous chest PA. This might help physicians detect congestive cardiomegaly for patients undergoing portable chest AP. PMID:22065900

    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.

    To describe plain radiographic and thin-section CT findings of hematogenous candida pneumonia in major burn patients. We reviewed nine cases of hematogenous candida pneumonia in major burn patients who had positive blood culture for candida and findings of pneumonia on plain chest radiograph. On five of nine cases, thin-section CT was done. We evaluated retrospectively nine cases for onset, the pattern, distribution, and size of lesions on plain chest radiograph and thin-section CT. On plain chest radiograph, randomly distributed 2-10 mm nodules were seen in six cases(66%) and randomly distributed 10-15 mm consolidations in remaining three cases(33%). Lesion occurred in 11th to 75th post-burn day(average, 34th post-burn day). Other findings were cardiomegaly in three cases, atelectasis in three cases, and pulmonary edema in one case. Thin-section CT showed variable shaped subpleural nodules in all five cases. The size of nodules were 1-5 mm in two cases(40%) and 5-10 mm(60%) in three cases. Feeding vessel signs were seen in two cases. Other findings were atelectasis in three cases, cardiomegaly in three cases, ground-glass opacity and interlobular septal thickenings by pulmonary edema in two cases. Plain chest radiographic findings of hematogenous candida pneumonia in major burn patients are randomly distributed nodules or consolidations of variable size. Thin-section CT findings are variable shaped subpleural nodules less than 1 cm

    2007-01-01

    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.)

    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)

    We present a case of pure erythroleukemia, diagnosed at autopsy, in a dysmorphic premature infant who died of multiorgan failure within 24 hours of birth. Dysmorphic features included facial and limb abnormalities with long philtrum, microagnathia, downturned mouth, short neck as well as abnormal and missing nails, missing distal phalanx from the second toe, and overlapping toes. Internal findings included gross hepatomegaly and patchy hemorrhages in the liver, splenomegaly, and cardiomegaly; and subdural, intracerebral, and intraventricular hemorrhages. Histology revealed infiltration of bone marrow, kidney, heart, liver, adrenal, lung, spleen, pancreas, thyroid, testis, thymus, and placenta by pure erythroleukemia. Only 6 cases of congenital erythroleukemia have been previously reported with autopsy findings similar to those of this case. The dysmorphic features, although not fitting any specific syndrome, make this case unique. Congenital erythroleukemia and possible syndromes suggested by the dysmorphic features are discussed.

    Color slides and black/white prints were made of the fundus of both eyes of 458 males age > 39 y, and the results related to age, blood pressure, duration of hypertension, and arteriole-venule (A-V) ratio. Evaluation of changes from color slides was similar to ophthalmoscopic findings. Frequency of abnormal findings increases with age, blood pressure, and hypertension; people with fundus abnormalities had a higher frequency of cardiomegaly, aortic calcification and tortuosity, and ECG abnormalities. Generalized narrowness of arterioles and changes in venule caliber at A-V crossing were the most frequently observed abnormalities. The A-V ratio can be related to generalized narrowness but not to either age, blood pressure, or hypertension. No correlation was observed between frequency of abnormal findings and estimated radiation dose among A-bomb survivors (5 tables, 4 figures). (DLC)

    Pulmonary artery hypertension with chronic pulmonary embolism is an uncommon entity that is potentially treatable with pulmonary embolectomy. Although the classic radiographic features have been described, several recent investigators report a significant percentage of these patients with normal chest radiographs. In a series of 22 patients, no normal radiographs were seen. Findings included cardiomegaly (86.4%) with right-sided enlargement (68.4%), right descending pulmonary artery enlargement (54.5%), azygos vein enlargement (27.3%), mosaic oligemia (68.2%), chronic volume loss (27.3%), atelectasis and/or effusion (22.7%), and pleural thickening (13.6%). Good correlation with specific areas of diminished vascularity was seen on chest radiographs compared with pulmonary angiograms.

    1981-01-01

    The radiological signs of transient tachypnoea are analysed via a study conducted with 9 children suffering from this disturbance of respiratory adaptation. The main signs are reticulonodular structural increases on both sides and extended vessels with unsharp outlines; to a lesser extent, marked small interlobar fissure, signs of an expiratory disturbance of ventilation, and cardiomegaly are seen also. Differentiation against hyaline membranes is easy and delineation against pneumonic and haemorrhagic infiltrations is usually not at all difficult. However, it may be less easy to differentiate between a relatively severe transient tachypnoea and cardiac left decompensation, since the radiological signs resemble each other. Assessment of a chest X-ray film of the newborn should be evaluated in such cases only if the clinical pattern of signs is known, since this is the only way to obtain adequate radiological clarification.

    2016-01-01

    Full Text Available We report a 2.5-year-old girl who presented with hoarseness of voice since 3 months of age and failure to thrive. Chest X-ray showed cardiomegaly with a deviation of the trachea and mediastinum to the right side. Two-dimensional echocardiography showed decreased flow across the right pulmonary artery, a small atrial septal defect (ASD with a right-to-left shunt, and a dilated right atrium and right ventricle with severe tricuspid regurgitation suggestive of severe pulmonary hypertension. A silent large patent ductus arteriosus was also seen. Multiple detector computerized tomography aortogram confirmed the findings of absent right pulmonary artery and hypoplastic right lung with small cystic lesions suggestive of congenital cystic adenomatoid malformation in the right lower lobe. Hoarseness of voice was due to the left vocal cord palsy probably secondary to severe pulmonary hypertension (Ortner′s syndrome.

    Full Text Available Both iron overload and iron deficiency have been associated with cardiomyopathy and heart failure, but cardiac iron utilization is incompletely understood. We hypothesized that the transferrin receptor (Tfr1 might play a role in cardiac iron uptake and used gene targeting to examine the role of Tfr1 in vivo. Surprisingly, we found that decreased iron, due to inactivation of Tfr1, was associated with severe cardiac consequences. Mice lacking Tfr1 in the heart died in the second week of life and had cardiomegaly, poor cardiac function, failure of mitochondrial respiration, and ineffective mitophagy. The phenotype could only be rescued by aggressive iron therapy, but it was ameliorated by administration of nicotinamide riboside, an NAD precursor. Our findings underscore the importance of both Tfr1 and iron in the heart, and may inform therapy for patients with heart failure.

    Wei-Ting Lai

    2013-12-01

    Full Text Available A 7-year-old boy developed a left ventricular aneurysm with massive hemopericardium 3 years ago due to a fall from a fourth-floor window. He had mild neurological sequelae including cranial nerve III palsy and abnormal electroencephalography findings at that time. He had no chest pain until recently when he presented with chest tightness and abdominal pain for 2 days prior to admission. Chest X-ray showed marked cardiomegaly. Echocardiography revealed massive pericardial effusion and a large left ventricular aneurysm. The massive hemopericardium was surgically drained, and the aneurysm was resected under cardiopulmonary bypass. He was discharged uneventfully 1 week after operation. Because symptoms and signs can vary in patients with ventricular aneurysm, we strongly suggest a close clinical follow-up, preferably with chest X-ray or echocardiography, for patients experiencing a blunt chest trauma.

    2007-01-01

    Full Text Available Post Partum Cardiomyopathy (PPCM is a relatively rare form of heart failure associated with pregnancy. It was recognized first in the 19th century by Ritchie and is defined as the onset of acute heart failure in the last trimester or early post partum period in the absence of infections, metabolic, toxic, ischaemic or valvular causes of myocardial dysfunction. Prognosis depends on the degree of cardiomegaly at presentation and in the following 6 months. Initial high risk period carries a mortality of 25 to 50%. Keeping in mind the reduced contractility and ejection fraction with ventricular dilatation proceeding to cardiac failure, the anesthesiologist managing a case of PPCM faces the challenge of avoiding myocardial depression, hypovolemia and increased SVR, all of which may be hazardous

    2011-01-01

    In the United States, approximately 100,000 infants are born to diabetic mothers each year. If diabetes in pregnancy is uncontrolled, the diversity of resulting health problems can have a profound effect on the embryo, the fetus, and the neonate. These infants are at risk for a multitude of physiologic, metabolic, and congenital complications such as macrosomia, asphyxia, respiratory distress, hypoglycemia, hypocalcemia, hyperbilirubinemia, polycythemia and hyperviscosity, cardiomegaly, and central nervous system disruption. Preconception control of glucose metabolism throughout the trajectory of a woman's pregnancy is a significant factor in decreasing the adverse impact of diabetes on the fetus and newborn. Meticulous attention to neonatal glucose levels, thorough physical examination, and precise diagnosis are prerequisites to appropriate care for the neonate.

    Anomalous origin of the left coronary artery from the pulmonary artery also recognized as Bland White Garland syndrome is a very rare congenital condition. A two-months old baby boy presented with dyspnoea for two weeks and a pansystolic murmur on auscultation. The base line investigations showed cardiomegaly and bilateral basal haze on X-ray chest. ECG showed ST elevation in leads l and AVl and echocardiography showed situs solitus, levocardia, hypokinetic intraventricular septum, ejection fraction of 30%, mitral regurgitation of grade-I and an anomalous origin of the left coronary artery from pulmonary artery was diagnosed. Patient was in left heart failure. It was rectified surgically by creating a transpulmonary tunnel (Takeuchi repair). Postoperative course was uneventful and he was finally discharged in stable condition. (author)

    The cardiological examination of 22 patients to be suspected of heart sarcoidosis (histologically established sarcoidosis, heart rhythm disturbances, cardiomegaly) has revealed thallium scan defects in 20 patients at rest and during exercise. In 19 patients pathologic left heart wall motions established by levocardiography applying the half axis method were found. The number of pathologic half axis shortenings correlated with ejection fraction, but not with left ventricular enddiastolic pressure and volume index, resp. Coronary heart disease could not be found by coronarography in any case. Myocardial biopsy did not show myocarditis. Cardiomyopathies, other specific heart muscle diseases or rheumatic myocarditis could not be excluded as causes of the results mentioned above. The follow-up examinations of the patients will give more detailed information on the etiology of the pathologic cardiac findings. (author)

    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.

    A 48-year-old man presented with complaints of shortness of breath and lower extremity swelling. His medical history was significant for hypertension on minoxidil and recent intracerebellar hemorrhage. Electrocardiography showed sinus tachycardia with left ventricular hypertrophy, and cardiomegaly was noted in the chest x-ray. The patient was hypertensive and tachypneic on admission. An echocardiogram taken immediately showed a large pericardial effusion with evidence of cardiac tamponade. He underwent immediate pericardiocentesis with drainage of 900 mL of pericardial fluid with significant improvement in the symptoms. Analysis of the pericardial fluid proved to be nondiagnostic. Infectious and rheumatologic causes were ruled out. After an extensive battery of tests, not yielding any diagnostic results, the pericardial effusion was attributed to minoxidil therapy. Closer monitoring is needed to prevent potentially fatal complications such as cardiac tamponade as in our patient.

    Full Text Available Human Chagas' disease, caused by the protozoan Trypanosoma cruzi, is associated with pathological processes whose mechanisms are not known. 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.

    A previously healthy 3-year-old boy presented to the emergency department with abdominal pain, fever, and emesis. Laboratory and radiologic evaluation for causes of acute abdomen were negative; however, review of the abdominal x-ray demonstrated cardiomegaly with the subsequent diagnosis of pericardial cyst by echocardiogram and computed tomography. The patient underwent surgical decompression and attempted removal of the cystic structure revealing that the cyst originated from the epicardium. His abdominal pain and fever resolved postoperatively and he completed a 3-week course of ceftriaxone for treatment of Propionibacterium acnes infected congenital epicardial cyst. Emergency department physicians must maintain a broad differential in patients with symptoms of acute abdomen to prevent complications from serious cardiac or pulmonary diseases that present with symptoms of referred abdominal pain.

    Tsutsugamushi disease is an acute febrile systemic disease caused by Rickettsia tsutsugamushi. Attention to Tsutsugamushi disease is increasing as it has recently been known that Tsutsugamushi disease is one of the epidemic febrile disease that occur in late fall in Korea. We analysed chest radiographic findings of 60 serologically confirmed Tsutsugamushi disease patients. 47 infiltration, mostly reticulonodular interstitial pattern. High resolution CT in a patient strongly supported that the lesions are interstitial location. 29 patients (62%) showed findings of hilar lymphadenopathy and septal lines were seen in 22 patients (47%). Other findings were cardiomegaly (10 patients), pleural effusion (6 patients), mediastinal lymphadenopathy (3 patients). Diffuse bilateral interstitial lung infiltration, hilar lymphadenopathy and septal lines are typical chest ratio graphic findings of Tsutsugamushi disease.

    A 4-month-old male infant with Bland-White-Garland (BWG) syndrome complicated myocardial infarction was reported. Signs included tachypnea, coughing, and failure to thrive. However, there was no sign of myocardial infarction. A chest radiograph revealed cardiomegaly (CTR = 65%) and electrocardiogram showed abnormal Q waves in I, aVL, V6 leads. Cardiac catheterization and angiography revealed marked dilatation of left ventricle (end-diastolic volume = 384 ml/m2) and extremely depressed ejection fraction (16%), confirming the diagnosis of BWG syndrome. A 201TlCl-myocardial SPECT demonstrated apical defect and hypoperfusion in the anterolateral, inferoposterior walls, whereas 123I-beta-methyl-p-iodophenylpentadecanoic-acid (123I-BMIPP) SPECT showed a wider defect area. SPECT studies with 201TlCl and 123I-BMIPP, are useful to assess myocardial viability more accurately in BWG syndrome.

    Left ventricular aneurysm (LVA) is an abnormal dilated heart structure, either congenital or acquired. LVA is a rare cardiac condition with no symptoms in most cases, thus occasionally diagnosed during investigations of other diseases. Its association with certain cardiac complications and sudden cardiac deaths has been reported. However, its role as a cause of sudden unexpected death is rare. The author reported a sudden cardiac death in a 29-year-old man with LVA. Without a significant coronary artery disease and known etiologies of LVA, such an abnormal heart structure in the present case was considered congenital LVA. As no other possible mechanisms of death could be identified other than LVA with its associated pathologic lesions, mural thrombi, and dilated cardiomegaly, his death was attributable to fatal cardiac arrhythmia (most commonly ventricular tachycardia) secondary to LVA. © 2017 American Academy of Forensic Sciences.

  3. Fournier gangrene and unexpected death.

    Fournier gangrene represents a rare but progressive perineal infection that may result in rapid death. A 70-year-old man with poorly controlled diabetes mellitus and alcohol abuse is reported who was found unexpectedly dead. He had last been contacted the night before his death. At autopsy, the most striking finding was deep necrotic ulceration of the scrotum with exposure of underlying deep muscles and testicles, with blood cultures positive for Escherichia coli. Death was, therefore, attributed to necrotic ulceration/gangrene of the perineum (Fournier gangrene) that was due to E. coli sepsis with underlying contributing factors of diabetes mellitus and alcoholism. In addition there was morbid obesity (body mass index 46.9), cirrhosis of the liver, and marked focal coronary artery atherosclerosis with significant cardiomegaly. Fournier gangrene may be an extremely aggressive condition that can result in rapid death, as was demonstrated by the rapid progression in the reported case. © 2012 American Academy of Forensic Sciences.

    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.

    Radiographic finding of the chest of toxemia in pregnancy and septicemia are observed during 4 years period from January 1968 to December 1971. There were 930 cases of toxemia in pregnancy and 14 cases of septicemia encounted among the total deliveries of 8295 cases in Ewha Womans University Hospital, Seoul, Korea. 1. The incidence of toxemia of pregnancy was 11.2% and that of septicemia was 0.2%. 2. Abnormalities of the chest roentgenogram of toxemia are analysed as cardiomegaly with pulmonary congestion and edema (20.7%), and other cases indicate pneumonitis. 3. In the case of septic pneumonia, 57.1% of its patient shows severe form, and in toxemia, 85% shows cardiac and pulmonary involvement in abnormal chest roentgenogram.

    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. 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. 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.

    Idiopathic pulmonary arterial hypertension (IPAH) is a rare disease in children. By definition it is a diagnosis of exclusion, and CT of the chest is primarily performed to exclude other causes. Previous studies have defined CT features suggestive of the diagnosis of IPAH, but these have all been limited to the adult population. Contrast-enhanced chest CT and high-resolution CT findings in IPAH were evaluated in an attempt to define features consistently seen in children with this condition. The chest CT scans performed at initial presentation were reviewed in 17 children with echocardiographic or angiographic evidence of IPAH. There were nine boys and eight girls, ranging in age from 1 month to 17 years. The extrapulmonary findings included cardiomegaly with right-sided cardiac enlargement, which was seen in 13 children. The central pulmonary arteries were enlarged in 15 children, with peripheral enlargement in two. In six children this resulted in bronchial compression. In addition, mediastinal and hilar lymphadenopathy was noted in three children. Prominent intrapulmonary features included a peripheral vasculopathy, with enlarged tortuous vessels, seen in eight children. Ill-defined ground-glass centrilobular opacities were also noted in eight children, representing the most common parenchymal abnormality. Other findings included septal lines in five, diffuse ground-glass opacification in four and focal hyperlucent zones in three. Mosaic attenuation was seen in one child. A variety of imaging findings are identified in IPAH. Features particularly consistent with the diagnosis include peripheral vasculopathy and centrilobular opacities in the setting of cardiomegaly and central pulmonary arterial enlargement. (orig.)

    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

    Convolutional neural networks (CNNs) are a subtype of artificial neural network that have shown strong performance in computer vision tasks including image classification. To date, there has been limited application of CNNs to chest radiographs, the most frequently performed medical imaging study. We hypothesize CNNs can learn to classify frontal chest radiographs according to common findings from a sufficiently large data set. Our institution's research ethics board approved a single-center retrospective review of 35,038 adult posterior-anterior chest radiographs and final reports performed between 2005 and 2015 (56% men, average age of 56, patient type: 24% inpatient, 39% outpatient, 37% emergency department) with a waiver for informed consent. The GoogLeNet CNN was trained using 3 graphics processing units to automatically classify radiographs as normal (n = 11,702) or into 1 or more of cardiomegaly (n = 9240), consolidation (n = 6788), pleural effusion (n = 7786), pulmonary edema (n = 1286), or pneumothorax (n = 1299). The network's performance was evaluated using receiver operating curve analysis on a test set of 2443 radiographs with the criterion standard being board-certified radiologist interpretation. Using 256 × 256-pixel images as input, the network achieved an overall sensitivity and specificity of 91% with an area under the curve of 0.964 for classifying a study as normal (n = 1203). For the abnormal categories, the sensitivity, specificity, and area under the curve, respectively, were 91%, 91%, and 0.962 for pleural effusion (n = 782), 82%, 82%, and 0.868 for pulmonary edema (n = 356), 74%, 75%, and 0.850 for consolidation (n = 214), 81%, 80%, and 0.875 for cardiomegaly (n = 482), and 78%, 78%, and 0.861 for pneumothorax (n = 167). Current deep CNN architectures can be trained with modest-sized medical data sets to achieve clinically useful performance at detecting and excluding common pathology on chest radiographs.

    The median age at presentation for dogs with patent ductus arteriosus (PDA) is closure is associated with a decrease in heart size and increased survival time, which are not well described in older dogs. To describe the clinical characteristics of dogs with PDA ≥5 years of age at the time of presentation to a veterinary referral hospital. 35 client-owned dogs. Retrospective case series. PDA was diagnosed at a median age of 7.4 years (range, 5.1-12.3 years). Females represented 23/35 (65.7%) of the patients. Concurrent heart disease included degenerative mitral valve disease (DMVD; 13), arrhythmias (11), pulmonary hypertension (7), and other congenital defects (2). Cardiomegaly was documented in the majority of dogs consisting of left ventricular enlargement (91%) and left atrial enlargement (86%). Median vertebral heart size in 24 dogs was 12.9 (range, 10.7-18.2). The PDA shunt direction was left-to-right in 33 and bidirectional in 2 dogs. Closure was performed in 26 dogs, including 4 with pulmonary hypertension. In 10 dogs receiving furosemide pre-operatively for management of heart failure, furosemide was discontinued (8) or the dosage decreased (2) at the time of discharge. Adult dogs can present with a left-to-right shunting PDA that results in cardiomegaly and clinical signs that can improve or resolve with PDA closure. This improvement is also apparent in dogs with PDA complicated by DMVD. Pulmonary hypertension that does not result in complete right-to-left shunting should not be considered a contraindication to closure. Copyright © 2017 The Authors.

  14. The pleura

    Kuhn, J.P.

    1985-01-01

    The thin, healthy parietal pleura casts such a fine shadow that it is invisible radiologically; visualization of it indicates that it has been pathologically thickened. The similarity of some of the shadows cast by normal structures in the thoracic wall to pleural shadows was discussed in a previous section. For purposes of description, the pleural space is divided into costal, mediastinal, interlobar, diaphragmatic, and apical portions. The normal visceral layer of the pleura closely adherent to the lung dips into the pulmonary fissures and is usually not visible in roentgenograms, but occasionally, in apparently healthy infants and children, portions of the interlobar fissures are visualized as fine, thin lines. Anomalous fissures commonly recognized include the azygos fissure and the inferior accessory fissure. Occasionally, the caudal end of the right major fissure is observed as a curved strip of increased density ascending laterally from the right leaf of the diaphragm. Davis found that this caudal segment is seen in the films of healthy children when it is ectopic and lies forward so that part of it is in axial projection when the patient is filmed in the frontal projection. The high incidence of this ''vertical fissure line'' in association with cardiomegaly is probably due to rotation of the fissure when the heart enlarges. Friedman noted that this longitudinal pleural line can occasionally be seen bilaterally and concluded that the presence of the line indicated local underaeration of the lung

    Full Text Available Dogs with the presumptive diagnosis of Chagas disease are commonly sent to our School of Veterinary Medicine by independent veterinarians. This prompted us to evaluate the prevalence of canine trypanosomiasis in some villages of the Central Valley of Costa Rica. A total of 54 dogs (21 males and 33 females from five rural villages, with ages between 3 months and 10 years old, were bled and submitted to three serological tests: indirect immunofluorescence, indirect hemagglutination and ELISA. Among all animals, 15 (27.7% revealed antibodies (6 pure bred and 9 mongrels and in 3 of them the parasite was also demonstrated by xenodiagnosis. All positive animals except 1, and 9 negative animals (control group were examined by X-rays and electrocardiography, revealing different degrees of cardiomegaly and ECG alteration, consistent with Chagas disease pathology in one dog (SA-11 of the infected ones. Examination of 50 inhabitants living in the houses where dogs and Triatoma dimidiata were found, yielded negative serological reactions. This was assumed to support the hypothesis that dogs are commonly infected by the oral route, a more effective means of infection compared with the vector transmission mechanism that occurs in humans.

    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.

    Full Text Available Symptomatic pulmonary arterial hypertension (PAH in patients with isolated atrial septal defect (ASD is rare during infancy. We report a case of isolated ASD with severe PAH in an infant who developed airway obstruction as cardiomegaly progressed. The patient presented with recurrent severe respiratory insufficiency and failure to thrive before the repair of the ASD. Echocardiography confirmed volume overload on the right side of heart and severe PAH (tricuspid regurgitation [TR] with a peak pressure gradient of 55 to 60 mmHg. The chest radiographs demonstrated severe collapse of both lung fields, and a computed tomography scan showed narrowing of the main bronchus because of an intrinsic cause, as well as a dilated pulmonary artery compressing the main bronchus on the left and the intermediate bronchus on the right. ASD patch closure was performed when the infant was 8 months old. After the repair of the ASD, echocardiography showed improvement of PAH (TR with a peak pressure gradient of 22 to 26 mmHg, and the patient has not developed recurrent respiratory infections while showing successful catch-up growth. In infants with symptomatic isolated ASD, especially in those with respiratory insufficiency associated with severe PAH, extrinsic airway compression should be considered. Correcting any congenital heart diseases in these patients may improve their symptoms.

  18. Acromegaly: Role of Surgery in the Therapeutic Armamentarium

    2012-01-01

    Full Text Available Acromegaly is a complex disease that requires the intervention of a multidisciplinary team. The most frequent clinical manifestations are growing of distal parts of the body and some areas of the face. Patients may also present arterial hypertension, diabetes mellitus, colonic polyps, cardiomegaly, neurological and endocrine changes secondary to the presence of a GH-secreting tumor in pituitary or extrapituitary origin, or eutopic hypothalamic GHRH hypersecretion and peripheral GHRH hypersecretion. Surgery is the first treatment used for most patients, regardless of the cause. In the great majority of cases, pituitary tumor can be removed through a transsphenoidal approach. Craniotomy is reserved for those cases with giant tumors, particularly when they grow toward the middle or posterior cranial fossa. Best surgical results are obtained when the tumor is confined into the sella turcica or if it has a regular suprasellar extension. When the disease cannot be controlled with surgery, medical treatment is indicated. Somatostatin analogues are included as the first line of medication, followed by dopamine agonist and growth hormone receptors antagonists. Radiation therapy can be also indicated in two main forms for residual tumor with medically refractory patients: radiosurgery for small tumors or fractionated stereotactic radiotherapy for larger ones.

    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.

    Full Text Available 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.

    2008-01-01

    Purpose: To determine thin-section computed tomography (CT) characteristics of acute eosinophilic pneumonia (AEP). Materials and methods: Thin-section CT scans of 29 patients (14 males, 15 females; mean age, 26 ± 15 years; age range, 15-72 years) with AEP were included this retrospective study. The clinical diagnosis of AEP was established by Allen's criteria. Each thin-section CT was reviewed by two observers. Results: Bilateral areas with ground-glass attenuation were observed on thin-section CT in all patients. Areas of air-space consolidation were present in 16 (55%) of 29 patients. Poorly defined centrilobular nodules were present in 9 patients (31%). Interlobular septal thickening was present in 26 patients (90%). Thickening of bronchovascular bundles was present in 19 patients (66%). Pleural effusions were present in 23 patients (79%) (bilateral = 22, right side = 1, left side = 0). The predominant overall anatomic distribution was central in only 2 (7%) of 29 patients, peripheral in 9 patients (31%), and random in 18 patients (62%). The overall zonal predominance was upper in 4 patients (14%), lower in 8 patients (28%), and random in 17 patients (58%). Conclusion: CT findings in AEP patients consisted mainly of bilateral areas of ground-glass attenuation, interlobular septal thickening, thickening of bronchovascular bundles, and the presence of a pleural effusion without cardiomegaly. The most common overall anatomic distribution and zonal predominance of the abnormal CT findings were random

    Full Text Available Echocardiographic aspects of chronic mitral valvular disease were studied and compared to physical, radiographic and electrocardiographic aspects. Seventy dogs were used, and clinical examination, thoracic radiography, electrocardiogram and echocardiogram were performed. Correlations between regurgitation severity with cardiac failure functional class and murmur intensity were observed. The electrocardiogram showed a low sensibility in detecting cardiac chamber enlargement, caused by mitral regurgitation. All the dogs with severe mitral regurgitation showed cardiomegaly according to thoracic radiographies.Avaliaram-se os aspectos ecocardiográficos da doença valvar crônica, comparando-os com os aspectos clínicos, radiográficos e eletrocardiográficos em cães. Estudaram-se 70 animais, realizando-se exames físicos, radiografias torácicas, eletrocardiograma e ecocardiograma. Observaram-se correlações entre a gravidade da regurgitação, a classe funcional da insuficiência cardíaca e a intensidade de sopro. O eletrocardiograma mostrou baixa sensibilidade para detectar aumento de câmaras cardíacas causadas por regurgitação mitral. Todos os cães com regurgitação mitral grave apresentaram cardiomegalia nas radiografias torácicas.

    Aim: To evaluate the role of cine magnetic resonance imaging (MRI) in the preoperative assessment and postoperative follow-up of patients undergoing left ventricular (LV) reduction surgery. Patients and Methods: 6 patients with cardiomegaly were examined on a 1.5 T MR imager before and after LV reduction surgery. The heart was imaged along the short and long axes using a breath-hold ECG-triggered cine gradient-echo sequence for assessing ventricular and valvular morphology and function and performing volumetry (end-diastolic and end-systolic volumes, ejection fraction). Results: Postoperatively, the mean ejection fraction increased from 21.7% to 33.4% and the enddiastolic and end-systolic left ventricular volumes decreased in all patients (304.0 and 252.5 ml before to 205.0 and 141.9 ml after surgery). Mean myocardial mass decreased slightly from 283.8 g to 242.7 g. Differences were significant for all parameters (p [de

    We report a case of a 30-year-old woman who suddenly collapsed after having a physical altercation with her husband. Despite immediate resuscitation, she died on arrival at the hospital. The victim's parents requested an autopsy because they believed that their daughter was killed by her husband. Postmortem examination revealed that the victim had a diffusely enlarged thyroid gland and cardiomegaly with left ventricular hypertrophy. There was no evidence of significant trauma on the body. Further postmortem thyroid function tests and review of her medical history indicated that her death was due to Graves' disease. To the best of our knowledge, this is the first case reported of sudden death due to cardiac arrhythmia from Graves' disease induced by physical and emotional stress associated with the criminal activity of another person. The autopsy findings are described. In addition, the literature is reviewed and the significance of postmortem evaluation of thyroid hormones in the cases of sudden death is discussed. © 2013 American Academy of Forensic Sciences.

    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.

    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

    Increased cardiothoracic ratio noted on chest radiographs often prompts concern and further evaluation with additional imaging. This study pools available data assessing the utility of cardiothoracic ratio in predicting left ventricular dilation. A systematic review of the literature was conducted to identify studies comparing cardiothoracic ratio by chest x-ray to left ventricular dilation by echocardiography. Electronic databases were used to identify studies which were then assessed for quality and bias, with those with adequate quality and minimal bias ultimately being included in the pooled analysis. The pooled data were used to determine the sensitivity, specificity, positive predictive value and negative predictive value of cardiomegaly in predicting left ventricular dilation. A total of six studies consisting of 466 patients were included in this analysis. Cardiothoracic ratio had 83.3% sensitivity, 45.4% specificity, 43.5% positive predictive value and 82.7% negative predictive value. When a secondary analysis was conducted with a pediatric study excluded, a total of five studies consisting of 371 patients were included. Cardiothoracic ratio had 86.2% sensitivity, 25.2% specificity, 42.5% positive predictive value and 74.0% negative predictive value. Cardiothoracic ratio as determined by chest radiograph is sensitive but not specific for identifying left ventricular dilation. Cardiothoracic ratio also has a strong negative predictive value for identifying left ventricular dilation.

    Marfan syndrome is rarely diagnosed in the neonatal period because of variable expression and age-dependent appearance of clinical signs. The prognosis is usually poor due to high probability of congestive heart failure, mitral and tricuspid regurgitations with suboptimal response to medical therapy and difficulties in surgical management. The authors have studied two cases of Marfan syndrome in the newborn period. Two cases of neonatal Marfan syndrome, one male and one female, were diagnosed by characteristic physical appearance. Both infants had significant cardiovascular abnormalities diagnosed by ultrasonography. Genetic DNA analysis in the second case confirmed the mutations in the fibrillin-1 gene located on chromosome 15q21 which is responsible for the development of Marfan syndrome. The boy died at six weeks of age with signs of rapidly progressive left ventricular failure associated with pneumonia. The second infant was having only mild signs of congestive heart failure and has been treated with beta blockers. At the age of 4 years her symptoms of congestive heart failure had worsened due to progression of mitral and tricuspid insufficiency and development of significant cardiomegaly. Mitral and tricuspid valvuloplasy had to be done at that time. Early diagnosis of Marfan syndrome in the newborn period can allow treatment in the early stages of cardiovascular abnormalities and may improve the prognosis. It also helps to explain to the family the serious health problem of their child.

    2015-01-01

    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 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.

    To evaluate the chest radiographic findings of rickettsial disease including murine typhus and tsutsugamushi disease in Chunchon. Chest radiographic films of 81 cases diagnosed as rickettsial disease(55 cases of tsutsugamushi disease, 26 cases of murine typhus) by immunofluorescence test were retrospectively analyzed. Main serotypes of Rickettsia tsutsugamushi were Gilliam and Karp. Incidence rate of tsutsugamushi disease was 2.1 times greater than that of murine typhus. Chest radiographs were abnormal in 63.6% of tsutsugamushi disease, and in 30.8% of murine typhus. Radiographic findings were Kerly's B line, reticulonodular densities, hilar enlargement, pleural effusion, and splenomegaly in both entities, but pulmonary consolidation was only found in tsutsugamushi disease. The patients with the abnormal radiographic findings were statistically well correlated with cardiomegaly ({rho} < 0.01) and azygos engorgement ({rho} < 0.05), as compared to the patients with normal radiographic findings. Radiographic findings of both murine typhus and tsutsugamushi disease were interstitial pattern. But the chest radiographs in patients with tsutsugamushi disease showed more severe pattern with higher rate of abnormality.

    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.

    We obtained the following results by reviewing the radiographic findings of 15 cases of Sinus valsalva rupture who were diagnosed surgically at Seoul National University Hospital since 1979. 1. Among distribution was from 15 years to 40 years with the mean age of 24 years. Among the 15 cases, 9 cases were male and 7 were female. 2. Ruptured sinus is right coronary sinus projecting to right ventricle in all 15 cases. Combined diseases are ventricular septal defect in 12 cases, Aortic Valvular heart disease in 4 cases, and narrowing of right ventricular outflow tract in 2 cases, and aneurysmal dilatation of right pulmonary artery in 1 cases. 3. Chest X-ray findings were that of left to right shunt, i.e, cardiomegaly, increased pulmonary vascularity but were normal in 3 cases. 4. Aortography showed sequential leakage of dye from right coronary sinus to right ventricle and finally to pulmonary artery in 9 cases, and in 9 cases of them the leakage is directly to right ventricular outflow tract without filling of sinus portion of the ventricle., i.e., type I. 5. The leakage was well shown in left ventricular diastolic phase and not shown in systolic phase. 6. Ventricular septal defects were not detected definitely in spite of taking left ventriculography. 7. Cine angiography is essential for detecting accurate site, degree and direction of sinus valsalva rupture and other associated cardiac abnormality.

    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.

    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)

    With increasing use of prospective scanning techniques for cardiac computed tomography (CT), meaningful evaluation of chamber volumes is no longer possible due to lack of normal values. We aimed to define normal values for mid-diastolic (MD) chamber volumes and to determine their significance in comparison to maximum volumes. Normal ranges at MD for left ventricular (LV) volume and mass and left atrial (LA) volume were determined from 101 normal controls. Thereafter, 109 consecutive CT scans, as well as 21 post-myocardial infarction patients, were analysed to determine the relationship between MD and maximum volumes. MD volumes correlated closely with maximal volumes (r = 0.99) for both LV and LA, and could estimate maximum volumes accurately. LV mass, measured at ED or MD, were very similar (r = 0.99). Abnormal MD volumes had excellent sensitivity and specificity to detect chamber enlargement based on maximal volumes (LV 86 %, 100 %, respectively; LA 100 %, 92 %, respectively). A single MD phase can identify patients with cardiomegaly or LV hypertrophy with a high degree of accuracy and MD volumes can give an accurate estimate of maximum LV and LA volumes. circle Traditionally, helical cardiac CT provided clinically important information from chamber volume analysis.

    Full Text Available Background: Homozygous familial hypercholesterolemia is a rare inherited metabolic disease caused by low-density lipoprotein receptor abnormality. Patients with homozygous familial hypercholesterolemia have an increased risk of cardiovascular complication that usually occurs in the first decade of life. Here, we report a 12-year-old girl with an unpredicted presentation for coronary artery disease and found to have homozygous familial hypercholesterolemia. Case Report: A 12-year-old girl was admitted to our unit with syncope. Chest X-ray showed bilateral diffuse pneumonic consolidation and mild cardiomegaly. We detected stable ST depression by electrocardiography. Echocardiography showed normal systolic functions. Troponin-1 levels were high (66 mcg/dL, upper limit: 0.04 mcg/dL. Influenza A virus DNA was detected by the respiratory viral panel. After her successful treatment for acute pneumonia and myocarditis due to Influenza A virus, her syncope attacks persisted. Marked ST elevation was observed during exercise electrocardiography. Coronary angiography showed severe occlusions in the coronary arteries. High serum levels of total cholesterol (756 mg/dL and low-density lipoprotein-C (556 mg/dL were noticed. She had no tendon xanthomas. Medical histories revealed that her family members were diagnosed with heterozygous familial hypercholesterolemia. A coronary bypass surgery was performed. Statin and ezetimibe treatments were started. We also planned lipid apheresis. Conclusion: Children with homozygous familial hypercholesterolemia may present with symptoms of premature coronary heart disease requiring a routine lipid test and careful anamnesis.

    Full Text Available Kazunori Otsui, Nobutaka Inoue, Anna Tamagawa, Kazuo OnishiDepartment of Cardiovascular Medicine, Kobe Rosai Hospital, Kobe, JapanAbstract: A 61-year-old diabetic woman with a mitochondrial A3243G mutation was hospitalized for evaluation of breathlessness, general fatigue, and leg edema. Chest radiography revealed cardiomegaly with massive pleural effusion. Serum lactate, pyruvate, and brain natriuretic peptide concentrations were elevated. Transthoracic echocardiography revealed a restrictive pattern of transmitral flow, although systolic function of the left ventricle was only mildly impaired. Based on these findings and her clinical course, the patient was diagnosed with right-sided heart failure caused by mitochondrial cardiomyopathy associated with a restrictive transmitral filling pattern. Treatment with furosemide, enalapril, and eplerenone was effective, and improvement in her symptoms was associated with amelioration of transthoracic echocardiographic findings and a reduction in serum brain natriuretic peptide levels. Previous reports have indicated heterogeneity in the clinical features of mitochondrial cardiomyopathy in patients carrying the A3243G mutation; the present case highlights the substantial variability in the clinical features of this disease.Keywords: mitochondrial disease, A3243G mutation, diastolic dysfunction, transmitral flow

    High titer of maternal thyroid-stimulating hormone receptor antibody (TRAb) in patients with Graves' disease could cause fetal hyperthyroidism during pregnancy. Clinical features of fetal hyperthyroidism include tachycardia, goiter, growth restriction, advanced bone maturation, cardiomegaly, and fetal death. The recognition and treatment of fetal hyperthyroidism are believed to be important to optimize growth and intellectual development in affected fetuses. We herein report a case of fetal treatment in two successive siblings showing in utero hyperthyroid status in a woman with a history of ablative treatment for Graves' disease. The fetuses were considered in hyperthyroid status based on high levels of maternal TRAb, a goiter, and persistent tachycardia. In particular, cardiac failure was observed in the second fetus. With intrauterine treatment using potassium iodine and propylthiouracil, fetal cardiac function improved. A high level of TRAb was detected in the both neonates. To the best of our knowledge, this is the first report on the changes of fetal cardiac function in response to fetal treatment in two siblings showing in utero hyperthyroid status. This case report illustrates the impact of prenatal medication via the maternal circulation for fetal hyperthyroidism and cardiac failure.

    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 99 mTc-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

    Over the last decades exercise training has evolved into an established evidence-based therapeutic strategy with prognostic benefits in many cardiovascular diseases (CVDs): In stable coronary artery disease (CAD) exercise training attenuates disease progression by beneficially influencing CVD risk factors (i.e., hyperlipidemia, hypertension) and coronary endothelial function. In heart failure (HF) with reduced ejection fraction (HFrEF) training prevents the progressive loss of exercise capacity by antagonizing peripheral skeletal muscle wasting and by promoting left ventricular reverse remodeling with reduction in cardiomegaly and improvement of ejection fraction. Novel areas for exercise training interventions include HF with preserved ejection fraction (HFpEF), pulmonary hypertension, and valvular heart disease. In HFpEF, randomized studies indicate a lusitropic effect of training on left ventricular diastolic function associated with symptomatic improvement of exercise capacity. In pulmonary hypertension, reductions in pulmonary artery pressure were observed following endurance exercise training. Recently, innovative training methods such as high-intensity interval training, resistance training and others have been introduced. Although their prognostic value still needs to be determined, these approaches may achieve superior improvements in aerobic exercise capacity and gain in muscle mass, respectively. In this review, we give an overview of the prognostic and symptomatic benefits of exercise training in the most common cardiac disease entities. Additionally, key guideline recommendations for the initiation of training programs are summarized. Copyright © 2014 Elsevier Inc. All rights reserved.

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

    International Nuclear Information System (INIS)

    Rottloff, R.

    1982-01-01

    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) [de

  12. Cerebral vascular disease in Hiroshima. Report of a six-year period of surveillance, 1958 to 1964

    1966-08-25

    Cerebral vascular disease (CVD) in the population of Hiroshima, Japan, is described for the period 1958 to 1964. The incidence of CVD in the male population over 30 years of age was 7.4 per 1000 per year and in females 4.1, approximately twice the observed incidence of coronary heart disease. Being based on examined individuals only, these estimates are biased downward, perhaps by a factor of 10%. The frequency of cerebral thrombosis was twice that of cerebral hemorrhage. These findings on incidence and type of CVD are in accord with the known high incidence of this disease in Japan but do not suggest that any disease other than atherosclerosis of the cerebral arteries is responsible. Hypertension, cardiomegaly (ascertained by ECG or chest film), and proteinuria were important factors in the risk of subsequent CVD. The singular association between hypertension and CVD, and the evidence that CVD is declining in Japan, the US and Europe during a period of widespread use of antihypertensive agents, encourage further epidemiologic study in CVD. 30 references, 15 figures, 8 tables.

    1981-01-01

    We evaluated 193 consecutive unstable angina patients by clinical features, hospital course and electrocardiography. All patients were managed medically. Of the 193 patients, 150 (78%) had a technetium-99m pyrophosphate (Tc-PYP) myocardial scintigram after hospitalization. Of these, 49 (33%) had positive scintigrams. At a follow-up of 24.9 +- 10.8 months after hospitalization, 16 of 49 patients (33%) with positive scintigrams died from cardiac causes, compared with six of 101 patients (6%) with negative scintigrams (p < 0.001). Of 49 patients with positive scintigrams, 11 (22%) had had nonfatal myocardial infarction at follow-up, compared with seven of 101 patients (7%) with negative scintigrams (p < 0.01). Age, duration of clinical coronary artery disease, continuing angina during hospitalization, ischemic ECG, cardiomegaly and a history of heart failure also correlated with cardiac death at follow-up. Ischemic ECG and a history of angina with a crescendo pattern also correlated with nonfatal infarction at follow-up. Patients with continuing angina, an ischemic ECG and a positive scintigram constituted a high-risk unstable angina subgroup, with a survival rate of 58% at 6 months, 47% at 12 months and 42% at 24 and 36 months. We conclude that the assessment of clinical features, hospital course, ECG and Tc-PYP scintigraphy may be useful in identifying high-risk unstable angina patients

Patients with continuing angina, an ischemic ECG and a positive scintigram constituted a high-risk unstable angina subgroup with a survival rate of 58% at 6 months, 47% at 12 months and 42% at 24 and 36 months. We conclude that the assessment of clinical features, hospital course, ECG and Tc-PYP scintigraphy may be useful in identifying high-risk unstable angina patients

    Full Text Available We report here a case of reexpansion pulmonary edema following laparoscopy-assisted distal gastrectomy (LADG for early gastric cancer. A 57-year-old Japanese woman with no preoperative comorbidity was diagnosed with early gastric cancer. The patient underwent LADG using the pneumoperitoneum method. During surgery, the patient was unintentionally subjected to single-lung ventilation for approximately 247 minutes due to intratracheal tube dislocation. One hour after surgery, she developed severe dyspnea and produced a large amount of pink frothy sputum. Chest radiography results showed diffuse ground-glass attenuation and alveolar consolidation in both lungs without cardiomegaly. A diagnosis of pulmonary edema was made, and the patient was immediately intubated and received ventilatory support with high positive end-expiratory pressure. The patient gradually recovered and was weaned from the ventilatory support on the third postoperative day. This case shows that single-lung ventilation may be a risk factor for reexpansion pulmonary edema during laparoscopic surgery with pneumoperitoneum.

    Scrub typhus (Tsutsugamushi disease) is an acute febrile systemic illness caused by Rickettsia Tsutsugamushi that is transmitted to humans by the bite of larval-stage trombiculid mites (chiggers). The authors analyzed chest radiographic findings of scrub typhus in 160 patients in Ulsan area. One hundred and eight (67.5%) of 160 patients showed abnormal findings which included lung lesions in 108 patients (67.5%), cardiomegaly in 37 patients (23.1%), lymphadenopathy in 25 patients (15.6%) and pleural effusion in 11 patients (6.9%). Among the lung lesions, interstitial patterns were seen in 107 patients (66.9%), mostly fine or medium reticulonodular, and air-space patterns in 14 patients (8.8%) and combined interstitial and air-space patterns in 13 patients (8.1%). Sixty-four patients (40%) had combined chest radiographic findings. The typical chest radiographic findings of scrub typhus would be helpful in evaluation of the causes of acute febrile illness that occur during late fall in the endemic area.

    To evaluate the chest radiographic findings of rickettsial disease including murine typhus and tsutsugamushi disease in Chunchon. Chest radiographic films of 81 cases diagnosed as rickettsial disease(55 cases of tsutsugamushi disease, 26 cases of murine typhus) by immunofluorescence test were retrospectively analyzed. Main serotypes of Rickettsia tsutsugamushi were Gilliam and Karp. Incidence rate of tsutsugamushi disease was 2.1 times greater than that of murine typhus. Chest radiographs were abnormal in 63.6% of tsutsugamushi disease, and in 30.8% of murine typhus. Radiographic findings were Kerly's B line, reticulonodular densities, hilar enlargement, pleural effusion, and splenomegaly in both entities, but pulmonary consolidation was only found in tsutsugamushi disease. The patients with the abnormal radiographic findings were statistically well correlated with cardiomegaly (ρ < 0.01) and azygos engorgement (ρ < 0.05), as compared to the patients with normal radiographic findings. Radiographic findings of both murine typhus and tsutsugamushi disease were interstitial pattern. But the chest radiographs in patients with tsutsugamushi disease showed more severe pattern with higher rate of abnormality

    A 5-month-old, intact male ferret (Mustela putorius furo) was presented with apathy, tachypnea and exercise intolerance. On initial physical examination, tachypnea and cyanosis were the two primary clinical signs detected. The complete blood count also revealed a severe polycythemia, with lymphopenia, neutrophilia and eosinophilia. Further diagnostic imaging tests were performed. The thoracic radiographs revealed cardiomegaly and a diffuse alveolar pulmonary pattern. Consequently, an echocardiography was performed and showed an interventricular septal defect, pulmonic artery occlusion, overriding of the aorta and right ventricle hypertrophy. All abnormalities were compatible with a tetralogy of Fallot (TOF). As a treatment plan, a phlebotomy was performed and the ferret was posteriorly maintained with oxygen and fluid therapy. The following day, the hematocrit decreased 11% and the respiratory distress improved. Four days later, the ferret got clinically worse and was euthanized. A necropsy was performed and confirmed the presence of an extreme TOF with a diffused interstitial pneumonia secondary to Pneumocystis carinii. To the author's knowledge, this is the first report of an extreme tetralogy of Fallot with polycythemia in a ferret. Copyright © 2017 Elsevier Inc. All rights reserved.

    Aminophylline [(theophylline ethylene diamine (TED)] reportedly improved cardiac hemodynamics by lowering vascular resistances and increasing contractility. TED as used clinically has not been compared to the vasodilator sodium nitroprusside (NP). To assess the relative hemodynamic effects of these two commonly used agents, the following comparison was made. Ten patients with congestive cardiomyopathy in chronic refractory heart failure [New York Heart Association (NYHA) class IV] were studied. All patients demonstrated cardiomegaly by chest x ray and echocardiography (LVd = 6.3 +/- 0.7 cm) and markedly abnormal hemodynamics during baseline observations (see Table I). Hemodynamic measurements at baseline were compared after TED infusion (mean blood level = 16 +/- 12 micrograms/m/TED) and during intravenous NP. No significant changes in heart rate occurred during either therapeutic intervention; a fall in mean arterial pressure of 10 mmHg (p TED. Theophylline ethylene diamine demonstrated no detectable cardiac hemodynamic effects 60--90 min post infusion despite proven blood levels, whereas NP exhibited distinctly beneficial effects in this patient group. Previous studies demonstrating improved hemodynamics occurring with TED have been limited to the time of infusion or within the following 40 min, a time when TED blood levels are maximum and therefore closest to toxicity. The results of this study suggest that TED demonstrates no beneficial hemodynamic effects in refractory heart failure as early as 1 h after infusion despite blood levels in the therapeutic range.

    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. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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.

    Purpose: To determine thin-section computed tomography (CT) characteristics of acute eosinophilic pneumonia (AEP). Materials and methods: Thin-section CT scans of 29 patients (14 males, 15 females; mean age, 26 {+-} 15 years; age range, 15-72 years) with AEP were included this retrospective study. The clinical diagnosis of AEP was established by Allen's criteria. Each thin-section CT was reviewed by two observers. Results: Bilateral areas with ground-glass attenuation were observed on thin-section CT in all patients. Areas of air-space consolidation were present in 16 (55%) of 29 patients. Poorly defined centrilobular nodules were present in 9 patients (31%). Interlobular septal thickening was present in 26 patients (90%). Thickening of bronchovascular bundles was present in 19 patients (66%). Pleural effusions were present in 23 patients (79%) (bilateral = 22, right side = 1, left side = 0). The predominant overall anatomic distribution was central in only 2 (7%) of 29 patients, peripheral in 9 patients (31%), and random in 18 patients (62%). The overall zonal predominance was upper in 4 patients (14%), lower in 8 patients (28%), and random in 17 patients (58%). Conclusion: CT findings in AEP patients consisted mainly of bilateral areas of ground-glass attenuation, interlobular septal thickening, thickening of bronchovascular bundles, and the presence of a pleural effusion without cardiomegaly. The most common overall anatomic distribution and zonal predominance of the abnormal CT findings were random.

    Full Text Available Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

    Full Text Available Graves disease (GD can lead to complications such as cardiac arrhythmia and heart failure. Although dilated cardiomyopathy (DCMP has been occasionally reported in adults with GD, it is rare in children. We present the case of a 32-month-old boy with DCMP due to GD. He presented with irritability, vomiting, and diarrhea. He also had a history of weight loss over the past few months. On physical examination, he had tachycardia without fever, a mild diffuse goiter, and hepatomegaly. The chest radiograph showed cardiomegaly with pulmonary edema, while the echocardiography revealed a dilated left ventricle with an ejection fraction (EF of 28%. The thyroid function test (TFT showed elevated serum T3 and decreased thyroid stimulating hormone (TSH levels. The TSH receptor autoantibody titer was elevated. He was diagnosed with DCMP with GD; treatment with methylprednisolone, diuretics, inotropics, and methimazole was initiated. The EF improved after the TFT normalized. At follow-up several months later, although the TFT results again showed evidence of hyperthyroidism, his EF had not deteriorated. His cardiac function continues to remain normal 1.5 months after treatment was started, although he still has elevated T3 and high TSH receptor antibody titer levels due to poor compliance with drug therapy. To summarize, we report a young child with GD-induced DCMP who recovered completely with medical therapy and, even though the hyperthyroidism recurred several months later, there was no relapse of the DCMP.

    2017-02-01

    Acromegaly is a clinical syndrome which results from growth hormone excess. Uncontrolled acromegaly is associated with cardiovascular mortality, due to an excess of risk factors including diabetes mellitus, hypertension and cardiomegaly. Diabetes mellitus is a frequent complication of acromegaly with a prevalence of 12-37%. This review will provide an overview of a number of aspects of diabetes mellitus and glucose intolerance in acromegaly including the following: 1. Epidemiology and pathophysiology of abnormalities of glucose homeostasis 2. The impact of different management options for acromegaly on glucose homeostasis 3. The management options for diabetes mellitus in patients with acromegaly RECENT FINDINGS: Growth hormone and IGF-1 have complex effects on glucose metabolism. Insulin resistance, hyperinsulinaemia and increased gluconeogenesis combine to produce a metabolic milieu which leads to the development of diabetes in acromegaly. Treatment of acromegaly should ameliorate abnormalities of glucose metabolism, due to reversal of insulin resistance and a reduction in gluconeogenesis. Recent advances in medical therapy of acromegaly have varying impacts on glucose homeostasis. These adverse effects influence management choices in patients with acromegaly who also have diabetes mellitus or glucose intolerance. The underlying mechanisms of disorders of glucose metabolism in patients with acromegaly are complex. The aim of treatment of acromegaly is normalisation of GH/IGF-1 with reduction of co-morbidities. The choice of therapy for acromegaly should consider the impact of therapy on several factors including glucose metabolism.

    Full Text Available It was reported previously that a Candida albicans water-soluble fraction (CAWS, including a mannoprotein and β-glucan complex, has strong potency in inducing fatal necrotizing arteritis in DBA/2 mice. In this study, histopathological changes and cardiac function were investigated in this system. One mg/day of CAWS was given to DBA/2 mice via peritoneal injection for five days. The CAWS-treated DBA/2 mice were induced aortitis and died at an incidence of 100% within several weeks. Histological findings included stenosis in the left ventricular outflow tract (LVOT and severe inflammatory changes of the aortic valve with fibrinoid necrosis. Cardiomegaly was observed and heart weight increased 1.62 fold (<0.01. Echocardiography revealed a severe reduction in contractility and dilatation of the cavity in the left ventricle (LV: LV fractional shortening (LVFS decreased from 71% to 38% (<0.01, and the LV end-diastolic diameter (LVDd increased from 2.21 mm to 3.26 mm (<0.01. The titer of BNP mRNA increased in the CAWS-treated group. Severe inflammatory changes resulting from CAWS brought about lethal LV dysfunction by aortic valve deformation with LVOT stenosis. This system is proposed as an easy and useful experimental model of heart failure because CAWS arteritis can be induced by CAWS injection alone.

    Objective: To describe and quantify the main changes seen on computed tomography of the chest in mildly symptomatic adult patients with sickle cell disease, as well as to evaluate the radiologist accuracy in determining the type of haemoglobinopathy. Materials and Methods: A prospective study involving 44 adult patients with sickle cell disease who underwent inspiration and expiration computed tomography of the chest. The frequency of tomography findings and the extent of involvement are reported. We also calculated radiologist accuracy in determining the type of haemoglobinopathy by analyzing the pulmonary alterations and morphology of the spleen. Results: The changes found on computed tomography scans, in descending order of frequency, were as follows: fibrotic opacities (81.8%); mosaic attenuation (56.8%); architectural distortion (31.8%); cardiomegaly (25.0%); lobar volume reduction (18.2%); and increased caliber of peripheral pulmonary arteries (9.1%). For most of the findings, the involvement was considered mild, five or fewer lung segments being affected. The accuracy in determining the type of haemoglobinopathy (HbSS group versus not HbSS group) was 72.7%. Conclusion: In adult patients with sickle cell disease, the main tomography findings reflect fibrotic changes. In addition, computed tomography can be helpful in differentiating among haemoglobinopathies. (author)

  10. Myocarditis exacerbation in a child undergoing inguinal hernioplasty after viral infection

    Simić Dušica

    2009-01-01

    Full Text Available Introduction Immunosuppressive effects of general anesthesia and surgery could have unexpected consequences in a child with recent infection. The incidence of myocarditis in childhood is unknown. Case outline During general anesthesia for inguinal hernia repair, a seven-year-old boy suddenly developed heart failure. Clinical presentation included hypotension, pulmonary edema, drop in hemoglobin oxygen saturation, ST segment elevation and premature ventricular contractions. Homodynamic stability and adequate oxygenation were achieved with dopamine and furosemide. Preoperative history, physical examination and complete blood count were unremarkable. Moderate cardiomegaly and pulmonary edema were present on chest radiography. Diminished left ventricular contractility found on echocardiography increased troponin I and CK-MB levels suggested myocardial injury. Increased C-reactive protein with lymphocytosis suggested inflammation as its cause. Parents failed to report rubella 10 days before the operation. A clinical diagnosis of myocarditis as a complication of rubella was based on increased titer of IgM to rubella. With intravenous immunoglobulin, corticosteroids and symptomatic treatment for heart failure, his condition improved and ejection fraction reached 68 % one month after operation. Conclusion In future, we need protocols with instructions for pediatric patients undergoing elective surgery and anesthesia after viral infections.

    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

    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.

    Hb Constant Spring (Hb CS, HBA2: c.427T > C) is a common nondeletional α-thalassemia (α-thal) that results from a nucleotide substitution at the termination codon of the α2-globin gene. Homozygosity for Hb CS (α(CS)α/α(CS)α) is relatively rare, and generally characterized with mild hemolytic anemia, jaundice, and splenomegaly. In this report we present a fetus with cardiomegaly, pericardial effusion, enlarged placenta and increased middle cerebral artery-peak systolic velocity (MCA-PSV) at 24 weeks' gestation. Fetal blood sampling revealed the severe anemia [hemoglobin (Hb) level being 4.8 g/dL] and Hb H (β4) disease-like hematological findings with Hb Bart's (γ4) level of 17.9%. DNA sequencing of the α-globin genes found that both partners were Hb CS carriers and the fetus was an Hb CS homozygote. Therefore, this was a rare case of homozygous Hb CS which demonstrated an unusual and serious anemia and hydrops fetalis in utero.

    Hb Zurich-Albisrieden [HBA2: c.178G > C; α59(E8)Gly→Arg (α2)] is a rare nondeletional α-thalassemia (α-thal) that results from a nucleotide substitution at codon 59 of the α2-globin gene. In this report, we present a fetus with cardiomegaly, enlarged placenta and increased middle cerebral artery-peak systolic velocity (MCA-PSV) at 25 weeks' gestation. Fetal blood sampling revealed the severe anemia [hemoglobin (Hb) level being 5.5 g/dL] and Hb H (β4) disease-like hematological findings with Hb Bart's (γ4) level of 30.7%. Molecular analysis of the family found that the father was an Hb Zurich-Albisrieden carrier, the mother heterozygous for the - - SEA α 0 -thal deletion, and the fetus was a compound heterozygote for Hb Zurich-Albisrieden and the - - SEA α 0 -thal deletion. Therefore, this was a rare case of Hb Bart's hydrops fetalis associated with Hb Zurich Albisrieden.

    Objective: To describe and quantify the main changes seen on computed tomography of the chest in mildly symptomatic adult patients with sickle cell disease, as well as to evaluate the radiologist accuracy in determining the type of haemoglobinopathy. Materials and Methods: A prospective study involving 44 adult patients with sickle cell disease who underwent inspiration and expiration computed tomography of the chest. The frequency of tomography findings and the extent of involvement are reported. We also calculated radiologist accuracy in determining the type of haemoglobinopathy by analyzing the pulmonary alterations and morphology of the spleen. Results: The changes found on computed tomography scans, in descending order of frequency, were as follows: fibrotic opacities (81.8%); mosaic attenuation (56.8%); architectural distortion (31.8%); cardiomegaly (25.0%); lobar volume reduction (18.2%); and increased caliber of peripheral pulmonary arteries (9.1%). For most of the findings, the involvement was considered mild, five or fewer lung segments being affected. The accuracy in determining the type of haemoglobinopathy (HbSS group versus not HbSS group) was 72.7%. Conclusion: In adult patients with sickle cell disease, the main tomography findings reflect fibrotic changes. In addition, computed tomography can be helpful in differentiating among haemoglobinopathies. (author)

  16. Pericardial Effusion due to Primary Malignant Pericardial Mesothelioma: A Common Finding but an Uncommon Cause

    Full Text Available This case report describes a 37-year-old female who was admitted to our Emergency Department because of shortness of breath. On physical examination, she had dyspnea and tachycardia and blood pressure was 80/50 mmHg with a pulsus paradoxus of 22 mmHg. Neck veins were distended, heart sounds were distant, and dullness was found on both lung bases. Her chest X-ray revealed bilateral pleural effusion and cardiomegaly. On both computed tomography and echocardiography the heart was of normal size and a large pericardial effusion was noted. The echocardiogram showed signs of impending tamponade, so the patient underwent an emergent pericardiocentesis. No infectious etiology was found and she was assumed to have viral pericarditis and was treated accordingly. However, when the pericardial effusion recurred and empirical therapy for tuberculosis failed, a pericardial window was performed. A typical staining pattern for mesothelioma was found on her pericardial biopsy specimen. Since no other mesodermal tissue was affected, a diagnosis of primary malignant pericardial mesothelioma was made. Chemotherapy was not effective and she passed away a year after the diagnosis was made. This case highlights the difficulties in diagnosing this uncommon disease in patients that present with the common finding of pericardial effusion.

    Myxedema coma (MC) is a rare, but often fatal endocrine emergency. The majority of cases that occur in elderly women with long-standing primary hypothyroidism are caused by particular triggers. Conversely, MC of central origin is extremely rare. Here, we report a case of MC with both central and primary origins. A 56-year-old woman was transferred to our hospital due to loss of consciousness; a chest x-ray demonstrated severe cardiomegaly. Low body temperature, bradycardia, and pericardial effusion suggested the presence of hypothyroidism. Endocrinological examination revealed undetectable levels of serum free thyroxine (T(4)) and free triiodothyronine (T(3)), whereas serum thyroid-stimulating hormone (TSH) levels were not elevated. The woman's serum anti-thyroid peroxidase antibody and anti-thyroglobulin antibody tests were positive, indicating that she had Hashimoto's thyroiditis. Provocative tests to the anterior pituitary revealed that she had TSH and growth hormone (GH) deficiency; however, GH levels were restored after supplementation with levothyroxine for 5 months. This was not only a rare case of MC with TSH deficiency and Hashimoto's thyroiditis; the patient also developed severe osteoporosis and possessed transient elevated levels of serum carcinoembryonic antigen (CEA). This atypical case may suggest the role of anterior pituitary hormone deficiencies, as well as hypothyroidism, in the regulation of bone metabolism.

  18. 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

    Respiratory system involvement in scrub typhus is seen in 20-72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed. The study cohort contained 398 patients. Common presenting complaints included fever (100%), generalized myalgia (83%), headache (65%), dyspnea (54%), cough (24.3%), and altered sensorium (14%). Almost half of the patients (49.4%) had normal chest radiographs. Common radiological pulmonary abnormalities included pleural effusion (14.6%), acute respiratory distress syndrome (14%), airspace opacity (10.5%), reticulonodular opacities (10.3%), peribronchial thickening (5.8%), and pulmonary edema (2%). Cardiomegaly was noted in 3.5% of patients. Breathlessness, presence of an eschar, platelet counts of 2 mg/dL had the highest odds of having an abnormal chest radiograph. Patients with an abnormal chest X-ray had a higher requirement of noninvasive ventilation (odds ratio [OR]: 13.98; 95% confidence interval CI: 5.89-33.16), invasive ventilation (OR: 18.07; 95% CI: 6.42-50.88), inotropes (OR: 8.76; 95% CI: 4.35-17.62), higher involvement of other organ systems, longer duration of hospital stay (3.18 ± 3 vs. 7.27 ± 5.58 days; Pscrub typhus have abnormal chest radiographs. Chest radiography should be included as part of basic evaluation at presentation in patients with scrub typhus, especially in those with breathlessness, eschar, jaundice, and severe thrombocytopenia.

    In a unit serving a population of three million, 60 hypertensive patients with renovascular disease were identified over a 10-year period. The presence of renovascular disease was usually suggested by intravenous urography (IVU), although this was falsely negative in 21 per cent of cases; isotope renography (IR) was normal in a similar proportion of patients (25 per cent). Eight patients were treated medically and 52 underwent surgical procedures; nephrectomy in 32, autotransplantation in 10, by pass graft in six and percutaneous transluminal angioplasty in four. Twenty-three per cent of patients were cured, 37 per cent improved and 40 per cent unchanged one year after surgery, but the response could not be accurately predicted. Clinical features were of some value in that those patients most likely to benefit from surgery were younger, had less severe hypertension of shorter duration, smoked less, had less severe retinopathy and less cardiomegaly. There was also a trend for those with better renal function and less electrocardiographic evidence of left ventricular hypertrophy to benefit from surgery. The IVU and IR did not predict response to surgery but arteriographic appearances of fibromuscular dysplasia indicated there should be a favourable response. The renal vein renin ratio, basal or stimulated, was of no prognostic value since approximately two-thirds of patients with ratios above or below the threshold value had some benefit from surgery. We conclude that the surgical treatment of renovascular hypertension is worthwhile but the number of patients suitable for surgery is small. Clinical features and the results of simple investigations provided the best guide to surgical outcome in our patients.

  1. Clinical studies on the thallium-201 myocardial scintiphotography in patient with ischemic heart disease

    1980-01-01

    Thallium-201 myocardial scintiphotography was performed in 41 patients with myocardial infarction, 13 with angina pectoris and 12 without coronary artery disease. 1) In patients with congestive heart failure, blood clearance of 201 Tl was delayed and radioactivity on the lung area increased compared with normal cases. 2) The scintillation camera image on a globular model containing 0.5 mCi of 201 Tl was recorded in a magnetic disk as 64 * 64 matrix. Myocardial area was estimated as an area where the count showed more than 55% of maximum counts of myocardium. On the myocardial area, cold area due to infarction was defined as an area where the count showed less than 70% of the maximum. 3) The infarct size (%) was calculated as an ratio of the number of matrix in cold area against to myocardial area on the images of ANT, LAO, and LAT view. The mean infarct size (%) was larger in the patient with cardiomegaly (CTR >= 55%) than those without it, and it was larger in the patients with high values of serum CPK or LDH than in those with low values of them. 4) The correlation coefficient between the mean infarct size (%) and direction of QRS vector at the maximum, 20 msec and 40 msec were r = 0.780, 0.672 and 0.766, respectively. 5) Mean values of MBF/CO (%) ratio were showing significant low in myocardial infarction and in angina pectoris. 6) The mean value of Myocardial blood flow (MBF) was showing significant low in myocardial infarction and in angina pectoris. MBF (ml/min/m 2 ) value expressed the states of coronary blood flow better than MBF/CO (%). (J.P.N.)

    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.

    An investigation on the relationship between dietary arsenic exposure and cardiovascular diseases was made. In Antofagasta Commune, northern Chile, since 1955 arsenic has polluted public drinking water. This environmental contamination is of geological origin. The concentration of arsenic in drinking water for the 1955 to 1970 period was 0.5980 ppM. In the period June 1970 to March 1972, the concentration decreased to 0.0815 ppM due to a water filtration plant which started operating in May 1970. Greater Santiago showed 0.00 ppM of arsenic in drinking water. Amongst 10 autopsied patients with chronic arsenical dermatosis from Antofagasta Commune, 9 showed marked fibrous intimal thickening of the arterial wall and/or restricted lumen of the left coronary artery, 2 of these 9 also exhibiting myocardial infarction. Of the 10 patients, 7 developed cardiomegaly, which was related to chronic exposure to dietary arsenic. Two series of patients with myocardial infarction under 40 years of age, one from Antofagasta Commune, the other from greater Santiago (not exposed to arsenic) were compared. The Yates corrected chi 2 value being 11.7776. The difference was statistically highly significant. In Antofagasta Commune, the number of cases which had myocardial infarction with chronic arsenical dermatosis were compared with the cases which showed, myocardial infarction without chronic arsenical dermatosis. The Yates corrected chi 2 value was 13.0395. A highly significant difference was detected. Children from the two cities were also compared. The number of cases with myocardial infarction showed a significant difference; Fisher's exact test yielded a P approximately equal to 0.004944, the Yates corrected chi 2 value being 20.7311. The number of children with systemic occlusive arterial disease from the two cities also exhibited a highly significant difference.

    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

    Full Text Available Abstract Background There have been no reports discussing which imaging procedures are truly necessary before treatment of endoscopically-diagnosed early gastric cancer (eEGC. The aim of this pilot study was to show which imaging examinations are essential to select indicated treatment or appropriate strategy in patients with eEGC. Methods In 140 consecutive patients (95 men, 45 women; age, 66.4 +/- 11.3 years [mean +/- standard deviation], range, 33-90 with eEGC which were diagnosed during two years, the pre-treatment results of ultrasonography (US and contrast-enhanced computed tomography (CT of the abdomen, barium enema (BE and chest radiography (CR were retrospectively reviewed. Useful findings that might affect indication or strategy were evaluated. Results US demonstrated useful findings in 13 of 140 patients (9.3%: biliary tract stones (n = 11 and other malignant tumors (n = 2. Only one useful finding was demonstrated on CT (pancreatic intraductal papillary mucinous tumor but not on US (0.7%; 95% confidential interval [CI], 2.1%. BE demonstrated colorectal carcinomas in six patients and polyps in 10 patients, altering treatment strategy (11.4%; 95%CI, 6.1-16.7%. Of these, only two colorectal carcinomas were detected on CT. CR showed three relevant findings (2.1%: pulmonary carcinoma (n = 1 and cardiomegaly (n = 2. Seventy-nine patients (56% were treated surgically and 56 patients were treated by endoscopic intervention. The remaining five patients received no treatment due to various reasons. Conclusions US, BE and CR may be essential as pre-treatment imaging examinations because they occasionally detect findings which affect treatment indication and strategy, although abdominal contrast-enhanced CT rarely provide additional information.

    Methamphetamine dependence is a major public health problem. This study examined the nature, and extent, of cardiovascular disease amongst cases of methamphetamine-related death in Australia, 2009-2015. Analysis of 894 cases of methamphetamine-related death with full autopsy reports retrieved from the National Coronial Information System. The mean age was 37.9yrs (range 15-69yrs) and 78.5% were male. A quarter (26.3%) of cases had enlarged hearts and left ventricular hypertrophy was diagnosed in 18.9%. Severe coronary artery disease was present in 19.0%, the left coronary artery being the vessel most frequently stenosed (16.6%). Replacement fibrosis (evidence of earlier ischaemic events) in the heart muscle was observed in 19.8% of cases, and cardiomyopathy was diagnosed in 5.5%. Histological evidence of hypertension was observed in 32.7% of cases. With the exception of cardiomyopathy, equally common amongst both sexes, cardiovascular disease was more common amongst males, and those aged >35yrs. Clinically significant levels of cardiovascular disease were also observed amongst cases where the cause of death was not attributed to cardiovascular disease: cardiomegaly (19.3%), left ventricular hypertrophy (14.6%), severe coronary artery disease (9.4%), replacement fibrosis (14.4%), cardiomyopathy (3.3%). Cardiovascular disease was highly prevalent, despite the relatively young age of cases. With methamphetamine use increasing rapidly in major regions, cardiovascular disease and cardiovascular-related death will likely increase amongst methamphetamine users.

    Jr(a) is a high-prevalence red cell (RBC) antigen. The clinical significance of anti-Jr(a) is controversial. When hemolytic disease of the fetus and newborn (HDFN) occurred, most reported cases were clinically mild. We report the first case of fatal HDFN due to anti-Jr(a). A 28-year-old Caucasian woman with transfusion history was monitored at the 29th week of pregnancy (G4P1). An ultrasound scan showed fetal cardiomegaly and hepatomegaly. An antibody directed against a high-prevalence antigen was detected, but without conclusive identification. An emergency cesarean section was performed at the 36th week. The newborn was hydropic and showed severe anemia. Death occurred 30 hours after birth. Serologic methods were performed to investigate the mother's RBCs and serum. An in vitro functional cellular assay and semiquantitative measurement of anti-Jr(a) were used to determine the clinical significance of the antibody. Anti-Jr(a) was identified in the serum and Jr(a-) phenotype was confirmed. The anti-Jr(a) titer was 1024, with predominant immunoglobulin (Ig)G1 and minor IgG4 subclasses. The functional cellular assay was consistent with an antibody unlikely to cause HDFN. Semiquantitative measurement of anti-Jr(a) showed a reactivity equivalent to a 25 IU per mL (5 microg/mL) concentration of anti-D, a value associated with a significant risk of HDFN. This is the first documented case of fatal HDFN due to anti-Jr(a). Therefore, we recommend close monitoring of pregnant women with a high-titer anti-Jr(a), especially those with an incompatible transfusion history and/or multiple pregnancies. This case report provides new arguments about the clinical significance of anti-Jr(a) in the transfusion setting.

    The efficacy and safety of sirolimus (SRL) plus tacrolimus (TAC) versus SRL plus cyclosporine (CsA) were compared in high-risk renal allograft recipients. Evaluable patients (448) were randomly assigned (1:1) before transplant to receive SRL+TAC or SRL+CsA with corticosteroids. Eligible patients were black and/or repeat transplant recipients, and/or those with high titer of panel-reactive antibodies. Demographics were similar between groups. Both treatments demonstrated equivalent efficacy of the composite endpoint at 12 months with efficacy failure rates of 21.9% vs. 23.2% (SRL+TAC vs. SRL+CsA, respectively, 95% CI -10.0 to 7.1, P=0.737). Biopsy-confirmed acute rejection rate (13.8% vs. 17.4%) and graft survival rate (89.7% vs. 90.2%) were similar (SRL+TAC vs. SRL+CsA, respectively). In evaluable patients (received at least 1 dose of study drug), renal function (calculated Nankivell glomerular filtration rate) was not superior in SRL+TAC versus SRL+CsA (54.5 vs. 52.6 mL/min, P=0.466); however, in on-therapy patients, glomerular filtration rate was significantly higher in SRL+TAC at most time points. At 12 months, there were no significant differences in rates of death, discontinuation because of adverse events, hypercholesterolemia, hyperlipemia, or proteinuria. Diarrhea and herpes simplex infections occurred significantly more often in SRL+TAC patients. Hypertension, cardiomegaly, increased creatinine, overdose (primarily calcineurin inhibitor toxicity), acne, urinary tract disorders, lymphocele, and ovarian cysts occurred significantly more often in SRL+CsA patients. This study demonstrated that SRL-based therapy was efficacious in high-risk renal allograft recipients in the first year after transplant, providing equivalent efficacy with CsA or TAC, similar graft survival, low biopsy-confirmed acute rejection rates, excellent renal function, and an acceptable safety profile.

    The prevalence of obesity is increasing worldwide. Obese children without hypertension are becoming an important health challenge. Complications of obesity in adults are well established, but in obese children, cardiac dysfunction has not been reported clinically. The present crosssectional study investigates subclinical systolic and diastolic dysfunction using echocardiographic modalities. Twentyfive youngsters with body mass index (BMI) >30 and 25 healthy children with BMI <25 were assigned into case and control group, respectively. In all participants, complete cardiovascular examination, electrocardiography, and echocardiography were fulfilled. Echocardiography surveys included standard, pulsed wave Doppler (PWD), and tissue Doppler imaging (TDI). SPSS software, version 24. The two groups were matched for age and sex. The resting heart rate and blood pressure were markedly higher in the obese group ( P = 0.0001) though they were within the normal range in either category. Ejection fraction in the two groups was similar. Left ventricular (LV) mass ( P = 0.0001), LV mass index ( P = 0.029), left atrialtoaortic diameter ratio ( P = 0.0001), and LV enddiastolic diameter ( P = 0.008) were significantly greater in the case group, indicating cardiomegaly and subclinical systolic and diastolic dysfunction. Except for the aortic velocity, all PWD variables were considerably lower in the case group, suggesting subclinical diastolic dysfunction. All TDI parameters varied significantly between the two categories. There was a direct correlation between isovolumetric relaxation time and BMI. Obesity in children without hypertension is associated with subclinical systolic and diastolic cardiac dysfunction. We propose the evaluation of blood pressure as well as myocardial performance using PWD and TDI in all obese children without hypertension, regularly.

    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

    Preeclampsia (PE) is a devastating disorder of pregnancy that classically presents with maternal hypertension and proteinuria after 20 wk of gestation. In addition to being a leading cause of maternal and fetal morbidity/mortality, epidemiological and prospective studies have revealed long-term consequences for both the mother and baby of preeclamptic pregnancies, including chronic hypertension as well as other cardiovascular diseases and metabolic derangements. To better understand the effect of in utero exposure of PE on offspring, we utilized the BPH/5 mouse, a spontaneous model of the maternal and fetal PE syndrome. We hypothesized that young BPH/5 offspring would have altered metabolic and cardiovascular phenotypes. Indeed, BPH/5 growth-restricted offspring showed excess catch-up growth by early adulthood due to hyperphagia and increased white adipose tissue (WAT) accumulation, with inflammation markers isolated to the reproductive WAT depot only. Both excessive WAT accumulation and the inflammatory WAT phenotype were corrected by pair-feeding young BPH/5 female mice. We also found that young BPH/5 female mice showed evidence of leptin resistance. Indeed, chronic hyperleptinemia has been shown to characterize other rodent models of PE; however, the maternal metabolic profile before pregnancy has not been fully understood. Furthermore, we found that these mice show signs of cardiovascular anomalies (hypertension and cardiomegaly) and altered signaling within the reproductive axis in early life. Future studies will involve challenging the physiological metabolic state of BPH/5 mice through pair-feeding to reduce WAT before pregnancy and determining its causal role in adverse pregnancy outcomes.

    The anti-Trypanosoma cruzi antibodies isotype profile in Chagas' disease has been studied in relation to different clinical manifestations. A high titer of IgG anti-T. cruzi antibodies is found in patients with cardiac involvement, while a high titer of IgA anti-T. cruzi antibodies is associated with digestive forms. The aim of this work was to analyze the IgG subclass reactivity of anti-T. cruzi antibodies in patients with chronic Chagasic cardiomyopathy. Twelve consecutive chagasic patients were analyzed for IgG subclass reactivity to a T. cruzi antigenic extract. They had a complete clinical evaluation, peripheral EKG, echocardiography, left ventriculogram, and coronariography. All patients came from rural areas of Mexico and had lived in endemic zones for over seven years. They presented left ventricular endsystolic dimension above 42 mm in 58% (7/12) and ejection fraction below 50% in 58% (7/12). We found that IgG1 and IgG2 anti-T. cruzi antibodies showed higher titer than IgG3 antibodies, with consistently low titer of IgG4 antibodies. Expression of the four IgG subclasses of anti-T. cruzi antibodies suggest a mixed Th1/Th2-like immune response under a probably continuous chronic antigenic stimulation. On the other hand, high levels of IgG2 anti-T. cruzi antibodies showed a tendency to be associated with severe cardiomegaly. Our results suggest that a mixed Th1/Th2-like immune response may take place in chronic chagasic patients under a chronic antigenic stimulation.

    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.

    Seventy-eight patients undergoing mitral valve surgery with or without replacement of the aortic valve also underwent procedures on the tricuspid valve over a period of 10 years. All patients were in functional class III or IV preoperatively. The procedures were performed in all patients with organic disease of the tricuspid valve (N = 44) and in those with moderate or severe functional tricuspid valvar regurgitation (N = 34). Seventy-one patients underwent DeVega's annuloplasty with or without commissurotomy. The overall mortality was 11.5%. 65 long-term survivors were followed up for a period of 6 months to 10 years (mean 5.3 years). Sixty-three patients were in functional class I or II at the last follow-up. Six patients had clinical evidence of mild to moderate tricuspid regurgitation. Regression of cardiomegaly (as judged by the chest radiograph and right ventricular hypertrophy seen in the electrocardiogram) was evident in most cases. Fifty-one of 54 patients evaluated by cross-sectional echocardiography were reported to have a functionally normal tricuspid valve. Doppler echocardiography in 28 patients showed no significant tricuspid regurgitation or stenosis in 26 patients. Eleven consecutive patients undergoing DeVega's annuloplasty were studied prospectively with pre- and postoperative Doppler echocardiography. Good correlation existed between right ventricular systolic pressures predicted by Doppler with those obtained preoperatively at cardiac catheterization. Postoperative Doppler echocardiography in these 11 patients showed complete restoration of competence of the tricuspid valve as well as normalisation of the right ventricular systolic pressure in 10 patients.

    We present a novel variant of the bag-of-visual-words (BoVW) method for automated medical image classification. Our approach improves the BoVW model by learning a task-driven dictionary of the most relevant visual words per task using a mutual information-based criterion. Additionally, we generate relevance maps to visualize and localize the decision of the automatic classification algorithm. These maps demonstrate how the algorithm works and show the spatial layout of the most relevant words. We applied our algorithm to three different tasks: chest x-ray pathology identification (of four pathologies: cardiomegaly, enlarged mediastinum, right consolidation, and left consolidation), liver lesion classification into four categories in computed tomography (CT) images and benign/malignant clusters of microcalcifications (MCs) classification in breast mammograms. Validation was conducted on three datasets: 443 chest x-rays, 118 portal phase CT images of liver lesions, and 260 mammography MCs. The proposed method improves the classical BoVW method for all tested applications. For chest x-ray, area under curve of 0.876 was obtained for enlarged mediastinum identification compared to 0.855 using classical BoVW (with p-value 0.01). For MC classification, a significant improvement of 4% was achieved using our new approach (with p-value = 0.03). For liver lesion classification, an improvement of 6% in sensitivity and 2% in specificity were obtained (with p-value 0.001). We demonstrated that classification based on informative selected set of words results in significant improvement. Our new BoVW approach shows promising results in clinically important domains. Additionally, it can discover relevant parts of images for the task at hand without explicit annotations for training data. This can provide computer-aided support for medical experts in challenging image analysis tasks.

    Echocardiographic and computed tomographic findings of a case of intrapericardial tumor are reported, and two other cases of mediastinal tumor are presented in a discussion of the differential diagnosis of intrapericardial from mediastinal tumors. Case report: A 7-year-old male complained of cough and dyspnea. Cardiomegaly had been pointed out at a mass X-ray examination about a month prior to the admission. Two-dimensional echocardiography revealed a massive anterior pericardial effusion and a fist-sized tumor with cystic structure. The tumor pushed the heart backward at the level of the aortic root. Non-gated computed tomography of the chest disclosed the size and location of the tumor, but failed to clarify the internal structure. The patient underwent successful removal of a tumor, 12 x 10 x 8 cm in size and 350 g in weight, originating from the left atrial wall. Histologically, the tumor was a fibrosarcomatous mesothelioma. Usually, an intrapericardial tumor is easily suspected by echocardiography by the presence of pericardial effusion, although there have been a few reports of intrapericardial tumors without pericardial effusion. Echocardiographic diagnosis of the intrapericardial tumor is difficult in such cases. Identification of the pericardium is necessary to diagnose whether a tumor is intra- or extrapericardial. This identification, however, is not always easy by echocardiography when the ultrasonic beams become tangent to the pericardium. The pericardium between the tumor and the heart could not be identified by echocardiography in our two cases of mediastinal tumor. Computed tomography is helpful in diagnosing the size and location of a mediastinal tumor. (author)

  18. 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

    Among US adults, utilization of pharmacotherapy for attention-deficit hyperactivity disorder (ADHD) has increased more than ninefold since 1995-1996. Potential contraindications to ADHD pharmacotherapy include serious cardiovascular disease (CVD) and, for stimulants, addictions and bipolar disorder (BPD). To assess the prevalence of potential contraindications among adults treated with ADHD pharmacotherapy. A retrospective cohort analysis was performed using the Truven Health MarketScan ® database. Subjects filled ≥ 1 prescription for atomoxetine or ≥ 1 stimulant in 2014-2015, were aged 18-64 years, commercially insured throughout observation, and diagnosed with ADHD on two or more medical claims. Diagnoses and medical procedures were measured in the 12 months prior to pharmacotherapy initiation. Metrics included serious CVD (cardiomegaly, cardiomyopathy, cerebrovascular occlusion, congestive heart failure, myocardial infarction, pacemaker, or valvular disorder) and any CVD (serious CVD, other atherosclerotic CVD, arrhythmia, congenital heart anomaly, or hypertensive heart disease). Rates of substance addiction or abuse were measured in a range to address nonspecific diagnostic coding. Only 2.0% of treated adults (n = 91,588) had one or more diagnosis indicating serious CVD. CVD prevalence increased monotonically with age. Of patients aged 55-64 years (n = 5,237), 7.2% had serious CVD; 15.9% had any CVD; and 1.9% had been hospitalized with one or more CVD. Of patients treated with stimulants (n = 87,167), 11.3-18.5% were diagnosed with addiction/abuse and 4.1% with BPD. CVD prevalence is generally low among adults using ADHD medication but increases with age. Although difficult to estimate precisely, the rate of addiction/abuse among stimulant-treated patients appears unexpectedly high. Further research should assess cardiovascular events and other potential harms associated with contraindicated use in high-risk adults.

    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.

    Dilated cardiomyopathy (DCM) is characterized by dilation and impaired contraction of the left ventricle or both ventricles. Among hereditary DCM, the genetic causes are heterogeneous, and include mutations encoding cytoskeletal, nucleoskeletal, mitochondrial, and calcium-handling proteins. We report three severely affected males, in a four-generation pedigree, with DCM phenotype who underwent cardiac transplant. Cardiomegaly with marked biventricular dilation and fibrosis were noticeable histopathological findings. The affected males had tested negative on a 46-gene pancardiomyopathy panel. Whole Exome Sequencing (WES) was performed to reveal mutation in the gene responsible in generation of DCM phenotypes. The 1-bp (Chr10:121435979delC; c.913delC) novel heterozygous deletion in exon 4 of BAG3, was identified in three affected males, resulted in frame-shift and a premature termination codon (p.Met306-Stop) producing a truncated BAG3 protein lacking functionally important PXXP and BAG domains. WES data were further utilized to map 10 SNP markers around the discovered mutation to generate shared disease haplotype in all affected individuals encompassing 11 Mb on 10q25.3-26.2 harboring BAG3. Finally genotypes were inferred for the unavailable/deceased individuals in the pedigrees. Here we propose that Chr10:121435979delC in BAG3 is a causal mutation in these subjects. Our and earlier studies indicate that BAG3 mutations are associated with DCM phenotypes. BAG3 should be added to cardiomyopathy gene panels for screening of DCM patients, and patients previously considered gene elusive should undergo sequencing of the BAG3 gene. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Full Text Available Background and Rationale: Respiratory system involvement in scrub typhus is seen in 20–72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. Materials and Methods: Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed. Results: The study cohort contained 398 patients. Common presenting complaints included fever (100%, generalized myalgia (83%, headache (65%, dyspnea (54%, cough (24.3%, and altered sensorium (14%. Almost half of the patients (49.4% had normal chest radiographs. Common radiological pulmonary abnormalities included pleural effusion (14.6%, acute respiratory distress syndrome (14%, airspace opacity (10.5%, reticulonodular opacities (10.3%, peribronchial thickening (5.8%, and pulmonary edema (2%. Cardiomegaly was noted in 3.5% of patients. Breathlessness, presence of an eschar, platelet counts of 2 mg/dL had the highest odds of having an abnormal chest radiograph. Patients with an abnormal chest X-ray had a higher requirement of noninvasive ventilation (odds ratio [OR]: 13.98; 95% confidence interval CI: 5.89–33.16, invasive ventilation (OR: 18.07; 95% CI: 6.42–50.88, inotropes (OR: 8.76; 95% CI: 4.35–17.62, higher involvement of other organ systems, longer duration of hospital stay (3.18 ± 3 vs. 7.27 ± 5.58 days; P< 0.001, and higher mortality (OR: 4.63; 95% CI: 1.54–13.85. Conclusion: Almost half of the patients with scrub typhus have abnormal chest radiographs. Chest radiography should be included as part of basic evaluation at presentation in patients with scrub typhus, especially in those with breathlessness, eschar, jaundice, and severe thrombocytopenia.

  3. Computer-aided diagnosis in medical imaging: historical review, current status and future potential.

    Computer-aided diagnosis (CAD) has become one of the major research subjects in medical imaging and diagnostic radiology. In this article, the motivation and philosophy for early development of CAD schemes are presented together with the current status and future potential of CAD in a PACS environment. With CAD, radiologists use the computer output as a "second opinion" and make the final decisions. CAD is a concept established by taking into account equally the roles of physicians and computers, whereas automated computer diagnosis is a concept based on computer algorithms only. With CAD, the performance by computers does not have to be comparable to or better than that by physicians, but needs to be complementary to that by physicians. In fact, a large number of CAD systems have been employed for assisting physicians in the early detection of breast cancers on mammograms. A CAD scheme that makes use of lateral chest images has the potential to improve the overall performance in the detection of lung nodules when combined with another CAD scheme for PA chest images. Because vertebral fractures can be detected reliably by computer on lateral chest radiographs, radiologists' accuracy in the detection of vertebral fractures would be improved by the use of CAD, and thus early diagnosis of osteoporosis would become possible. In MRA, a CAD system has been developed for assisting radiologists in the detection of intracranial aneurysms. On successive bone scan images, a CAD scheme for detection of interval changes has been developed by use of temporal subtraction images. In the future, many CAD schemes could be assembled as packages and implemented as a part of PACS. For example, the package for chest CAD may include the computerized detection of lung nodules, interstitial opacities, cardiomegaly, vertebral fractures, and interval changes in chest radiographs as well as the computerized classification of benign and malignant nodules and the differential diagnosis of

    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

    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

Las manchas hipocrómicas asociadas con espasmos infantiles o cardiomegalia en lactantes y la evidencia de crisis epilépticas y angiofibromas faciales en la infancia tardía, constituyen las formas habituales de presentación de le enfermedad, aunque no es raro observar formas paucisintomáticas en la adultez. Los nódulos subependimarios, las tuberosidades corticales y los astrocitomas de células gigantes son las manifestaciones neuropatológicas características de este proceso, identificables radiológicamente mediante tomografía axial computadorizada y resonancia magnética nuclear craneales. El diagnóstico precoz permite brindar consejo genético a los padres; y la evaluación periódica de los casos, la identificación temprana de posibles complicaciones.An updated review on the clinical, radiological and neuropathological pecularities of tuberous sclerosis is made. This is the most representative of the neurocutaneous diseases that evolve with hypochromic stains and is the second in frequency of pharcomatosis. The hypochromic stains associated with infantile spasms or cardiomegaly in infants and the evidence of epileptic seizures and facial angiofibromas in late childhood are the habitual forms of presentation of this disease, although it is not rare to observe oligosymptomatic forms in adults. The subepindemal nodules, the cortical tuberosities and the astrocytomas of giant cells are the characteristic neuropathological manifestations of this process that may be radiologically identified by CAT and cranial magnetic resonance imaging. The early diagnosis allows to give genetic counseling to parents, to periodically evaluate the cases, and to identify the

Also, by opening ATP-sensitive potassium channels, it causes vasodilatation with the reduction in both afterload and preload. Because of the long halflife, its effects last for up 7 to 9 days after 24-hour infusion. Case report. We presented three patients 2, 15 and 17 years old. All the patients had severe acute deterioration of the previously diagnosed chronic heart failure (dilatative cardiomyopathy; univentricular heart with bidirectional Glenn anastomosis and restrictive bulboventricular foramen; bacterial endocarditis on artificial aortic valve with severe stenosis and regurgitation. Signs and symptoms of severe heart failure, cardiomegaly (cardio-thoracic index 0.65 and left ventricular dilatation (end-diastolic diameter z-score 2.6; 4.1 and 4.0 were confirmed on admission. Also, myocardial contractility was poor with ejection fraction (EF - 27%, 25%, 35%, fractional shortening (FS - 13%, 11%, 15% and stroke volume (SV - 40, 60, 72 mL/m2. The treatment with standard intravenous inotropic agents resulted in no improvement but in clinical deterioration. Thus, standard intravenous inotropic support was stopped and levosimendan treatment was introduced. All the patients received a continuous 24-h infusion 0.1 μg/kg/min of levosimendan. In a single patient an initial loading dose of 11 μg/kg over 10 min was administrated, too. Levosimendan treatment resulted in both clinical and echocardiography improvement with the improved EF (42%, 34%, 44%, FS (21%, 16%, 22% and SV (59, 82, 93 mL/m2. Hemodynamic improvement was registered too, with the reduction in heart rate in all the treated patients from 134-138 bpm before, to less than 120 bpm after the treatment. These parameters were followed by the normalization of lactate levels. Nevertheless, left

    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

    Full Text Available A citomegalovirose congênita sintomática é entidade clínica de grande importância devido a sua vasta sintomatologia fetal. No Brasil, o diagnóstico intra-útero é ainda pouco realizado, apesar do grande arsenal propedêutico. Relatamos um caso de citomegalovirose congênita grave com hepatoesplenomegalia, agenesia parcial do vérmix cerebelar, calcificações intracranianas, placentomegalia, aumento da ecogenicidade intestinal e renal, cardiomegalia, hipoplasia pulmonar, derrame pericárdico e ascite. A ressonância nuclear magnética fetal foi utilizada para confirmação dos achados ultra-sonográficos. A amniocentese foi realizada para análise do líquido amniótico por meio da PCR, sendo evidenciado resultado positivo. O óbito fetal foi constatado na 31ª semana de gestação, sendo confirmados os achados através da citopatologia e estudo anatomopatológico do natimorto. O arsenal propedêutico existente, na atualidade, para diagnóstico intra-útero da citomegalovirose congênita é de grande importância para confirmação diagnóstica e determinação do prognóstico fetal.Congenital cytomegalovirus infection is an important clinical entity, due to its sonographic symptomatology. In Brazil, in utero diagnosis is not accomplished despite the improvements in diagnostic methods. We report a congenital infection including: splenomegaly and hepatomegaly, hypoplasia of the cerebellar vermis, intracranial calcifications, hyperechoic kidneys, hyperechoic bowel, cardiomegaly, lung hypoplasia, ascites, and pericardial effusion. Fetal magnetic resonance imaging confirmed the sonographic findings. Amniocentesis was performed for cytomegalovirus PCR in amniotic fluid, which confirmed fetal infection. Fetal loss occurred in the 31st week of pregnancy. Necropsy studies confirmed the sonographic findings. The diagnostic methods have been useful to confirm congenital cytomegalovirus infection and to establish fetal outcome.

    Full Text Available Resumen: El tumor fantasma es una efusión interlobal pulmonar, interpretada como una manifestación radiológica poco común en personas con falla cardíaca descompensada; una vez se establece el tratamiento, estas lesiones que inicialmente se pueden confundir con infecciones o lesiones tumorales, desaparecen, por lo cual es fundamental realizar un diagnóstico adecuado que evite la práctica de estudios invasivos y no invasivos. Se expone el caso de un hombre con antecedente de falla cardíaca congestiva, quien ingresó al servicio de urgencias por exacerbación de síntomas respiratorios, edemas de miembros inferiores, disnea paroxística nocturna, ortopnea y signos clínicos de falla cardíaca. La radiografía de tórax mostró cardiomegalia, engrosamiento pleural derecho periférico y dos imágenes de tipo masa en tercios medio e inferior derechos y opacidad intersticial en bases. Se estableció manejo médico para falla cardíaca y se ordenó radiografía de tórax tres días después del tratamiento, luego de lo cual se observó desaparición de lesión intrapulmonar, confirmando diagnóstico de tumor fantasma. Abstract: The phantom (evanescent tumour is an interlobar lung effusion, interpreted as a rare radiological sign in individuals with decompensated heart failure. Once the treatment is established, these lesions, which initially can be confused with infections or tumour lesions, disappear. This makes it essential to make an appropriate diagnosis that avoids carrying out invasive and non-invasive studies. The case is presented of a man with a history of congestive heart failure, who was admitted to the Emergency Department due to the exacerbation of respiratory symptoms, swelling in the legs, paroxysmal nocturnal dyspnoea, orthopnoea, and clinical signs of heart failure. The chest x-ray showed cardiomegaly, right pleural peripheral thickening, and two mass-type images in the right middle and lower thirds, as well as interstitial

    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 There is no standardised criterion on the handling of Classical Sudden Infant Death Syndrome (SIDS and Gray Zone SIDS. Particularly international discussion is needed on the handling of Gray Zone cases. Autopsy findings for Classical SIDS and Gray Zone SIDS in Japan has been analysed in preparing the basic data for this discussion in this report. The material analysed was found in the Japanese Pathology and Autopsy Report from the Japanese Society of Pathology (January 1982 to December 1986. A x2 test was required to find the difference between Classical SIDS and Gray Zone SIDS in each autopsy finding. In addition, factor analysis (the principal factor method with Varimax rotation was carried out to identify the structure of the autopsy findings not only for Gray Zone SIDS but also for Classical SIDS. Using the x2 test a lymph tissue enlargement was found to have a high statistical value in Classical SIDS. Congestion, thymus enlargement, pulmonary oedema, adrenal gland atrophy, lymph tissue enlargement and neonate were recorded with .high factor loadings in Classical SIDS by factor analysis. Pneumonia, premature baby, and cardiomegaly was recorded with high statistical value in Gray Zone SIDS by the x2 test. Asphyxia, congestion, atelectasis, pulmonary emphysema, adrenal gland atrophy, premature baby, thymus hypoplasia, cardial malformation and ectopic hemopoesis were recorded as having high factor loadings in Gray Zone SIDS using factor analysis. Thymus enlargement and adrenal gland atrophy were recorded in the third factor of Gray Zone SIDS having rather high negative factor loading using factor analysis. It is remarkable that asphyxia was extracted in the first factor of Gray Zone SIDS with the highest loading factor using factor analysis. This fact might suggest indirectly that a percentage of Gray Zone SIDS would be underdiagnosed because of a substitutional diagnosis of asphyxia as being an external cause of death in Japan, even in general

  14. Dietary manipulation and social isolation alter disease progression in a murine model of coronary heart disease.

    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

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.

    obtained indicated that the chagasic patients are predominantly alloctones with low-grade schooling, and were exposed to triatomines. 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.

  17. CLINICAL PROFILE OF ANAEMIA IN A TERTIARY CARE HOSPITAL

    2016-04-01

    Full Text Available BACKGROUND Anaemia causes a reduction in the oxygen carrying capacity of the blood resulting in tissue hypoxia. Cardiac output at rest is not usually increased in most chronic anaemia until haemoglobin levels fall below 7 g/dL, but abnormal rise in output with exercise may occur with levels as high as 10 g/dL. The increase in cardiac output has been observed to correlate well with the degree of anaemia. Other compensatory mechanisms to chronic anaemia available to the body include decreased circulation time and increased tissue oxygen uptake. The latter is facilitated by a shift to the right of the oxygen haemoglobin dissociation curve. Cardiomegaly may also be as a result of the increased workload on the heart from the increased viscosity of blood in anaemia patients. Anaemia in the elderly is an extremely common problem that is associated with increased mortality and poorer health-related quality of life, regardless of the underlying cause of the low haemoglobin. A study of anaemia in elderly patients found a wide variation in prevalence, ranging from 2.9% to 61% in men and 3.3% to 41% in women. Higher rates were found in hospitalised patients than in community dwellers. It is easy to overlook anaemia in the elderly, since such symptoms as fatigue, weakness, or shortness of breath may be attributed to the ageing process itself. Our objective is to show the prevalence of anaemia even in a tertiary health care centre. METHODS One hundred patients were identified who were admitted in the Department of Medicine, Deccan College of Medical Sciences. Among the 100 patients, 38 were male and 62 were female. The study was conducted from Jan 2014 To Jan 2015. Patients having haemoglobin less than 10 g% in the medical wards were enrolled in the study. RESULTS Among the 100 patients, 38 were male and 62 were female. The average haemoglobin was 6.4 g%, the lowest being 2.8 g%. Peripheral blood smear showed hypochromic picture in 58, macrocytic picture in

    phenotypic characteristics to Human Muscular Dystrophy and are considered a proper animal model for DMD studies. Latero-lateral and dorso-ventral thoracic radiographies were obtained from 10 Golden Retriever dogs affected by muscular dystrophy, to investigate possible radiographic alterations. Thorax radiographic examination revealed (a interstitial and alveolar pattern, (b initial phases of pneumonia and pulmonary edema, (c cardiomegaly as a principal alteration in the thoracic cavity, (d megaesophagus displacing the trachea and heart silhouette, and (e cranial protrusion of the diaphragm lining into the thorax with development of a hiatus hernia displacing the stomach to the caudal mediastinum. Postmortem examination showed pleural effusion, pulmonary emphysema, degenerative and metaplasic processes in the diaphragm and intercostal muscles. Radiographic examination was considered essential for the diagnosis of cardiac and respiratory disease in Golden Retriever dogs affected by muscular dystrophy, and to identify the primary pulmonary process and to provide the establishment of suitable therapeutic treatment, with a reserved prognosis in advanced stage of the disease.

    risk factors for mortality. 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.

    formas crõnicas sintomáticas são de reprodução experimental imprevisível. O presente trabalho objetivou caracterizar os aspectos da patologia da doença de Chagas no cão, tentar as suas correlações eletrocardiográficas, os seus aspectos evolutivos, com a finalidade de fornecer elementos para estudos futuros com o referido modelo experimental.Young dogs experimentally infected with Trypanosoma cruzi developed acute disease and were studied by pathologic, immunologic, parasitologic and eletrocardiographic methods. The main lesion was an acute myocarditis that began in the atria and propagated through the septum toward the ventricles and, when fully developed, predominated in the right atrium, the right half of the ventricular septum and the free wall of the right ventricle. ECG changes were progressive and reflected the predominant atrial involvement. Cardiac blocks appeared only at the terminal stages and coincided with severe inflammation and necrosis along the A-V conducting tissue. Specific treatment made in 15 dogs with severe acute disease frequently reversed both the histological and ECG changes. Ten animals went into a chronic asymptomatic stage of the infection, three of them after being treated, and were observed from periods of 8 months to 3 years. None of them developed signs of congestive cardiac failure. ECG changes were both non-specific and transient. However, there were focal areas of fibrosis, sclero-atrophy and fatty replacement within the conducting tissue of the heart, probably sequelae from the lesions occuring during the acute infection. There were focal and mild myocarditis in some of the cases. The chronic cardiac form of the disease was studied in microscopic slides from one typical case. This dog developed chronic progressive cardiac failure and complete right bundle branch block 18 months after inoculation. There were cardiomegaly and chronic progressive diffuse myocarditis with fibrosis. Thus, the canine model of Chagas' disease

    hemoptysis in adults. Interventions such as pulmonary artery reconstruction and lobectomies were performed in 17% of the cases. We analyzed four of these cases, two in natural evolution and two with late term PH regression after surgical correction. METHODS: Three 22,10 and 35 month old male children and one 20 month old female child were included in the study. The 22 month old presented right-sided heart failure (RHF and cyanosis; the 10 month old presented RHF and the other two presented exertion fatigue. All had PH symptoms, right ventricular strain on the EKG and cardiomegaly. Cardiac catheterization showed systemic pressures in the contralateral pulmonary artery, with right-sided agenesis in three of the children and left-sided agenesis in one child. RESULTS: Surgical correction of pulmonary artery continuity was possible in the 22 month old and 10 month old using a 7mm diameter Goretex conduit between the pulmonary arteries up to the hypoplastic contralateral pulmonary hilum. There was early and late regression of the PH signs and the children remained stable during follow-up to the ages of 7 and 2.5 years, respectively. The pressure ratio between the left and right ventricles was 30 and 40%, in both cases. Pulmonary perfusion increased from 8 to 44% and from 8 to 23%, in the two cases. The same procedure was scheduled for the other patients. CONCLUSION: This technique has become the operation of choice for similar cases, that are rarely described in literature, even in the presence of severe PH and contralateral pulmonary artery hypoplasia.
