The clinical profile of 28 consecutive patients admitted with infective endocarditis (IE) between 1987 and 1988 was studied. There were 21 males and seven females with a mean age of 24 +/- 11 years. Rheumatic heart disease (RHD) was the commonest underlying disease (68%) followed by congenital heart disease (CHD). Mitral regurgitation with aortic regurgitation were the commonest valvular lesions (47%) in those with RHD while ventricular septal defect was the commonest (43%) in those with CHD. A younger age of onset, complicated course and high mortality were seen in these six patients with acute IE. Persistently positive blood cultures during life or at autopsy were obtained in 21%. Strep viridans was the commonest isolate and was often resistant to streptomycin. 2D echocardicgram revealed vegetations in 96% of patients, the aortic valve (39%) being more commonly affected than the mitral valve (11%). ESR of more than 20 mm drop 1st hour (Wintrobe) was seen in 96%. Thrombophlebitis was a common complication of therapy and cloxacillin the commonest drug implicated. A mortality of 21% as a result of refractory congestive heart failure (CHF) (50%), uncontrolled sepsis (33%) and embolic events (17%) was seen. A rising incidence of culture negative IE, combined aortic and mitral valve disease and CHF is noted.

A total of 99 cases of viridans streptococcal endocarditis encountered during the period of 1973 and 1990 at the Veterans General Hospital-Taipei were reviewed to evaluate its prognostic factors. Applying strict clinical and laboratory criteria, 24 cases were categorized as definite, 44 probable, 23 possible and 8 likely. The symptoms were frequently subtle and atypical but initial laboratory tests gave useful indications: 69.1% with leukocytosis, 78% with anemia, 58.5% with elevation of LDH level, 88.9% with elevation of ESR value and 100% with elevation of CRP level. Furthermore, 32.4% of the cases demonstrated proteinuria and 67.4% microscopic hematuria. Seventy-three of the subjects had a history of underlying heart disease, predominantly rheumatic heart disease. Histological examination and echocardiography revealed that 51 patients suffered from vegetative endocarditis, 7 (13.7%) of whom were found to have anatomically confirmed vegetations without initial echocardiographic evidence, Vascular events were seen in 61 cases (61.6%): peripheral stigmata (32 cases), cerebral vascular accidents (17 cases), pulmonary embolism (10 cases) and others (2 cases). The overall mortality rate was 18.2%. Congestive heart failure with embolization was the most common cause of death in this group. The presence of vegetation was not well correlated with embolic events. There was no statistically significant association between the mortality and the following characteristics: age, sex, underlying heart disease, evidence of echocardiographically detected vegetations, major surgical intervention and recurrent cases except for embolic events (p less than 0.01). In conclusion, viridans streptococcal endocarditis complicated embolic events usually presented with a fulminant course and a grave outcome.

We present a case history of 29-year old female with infective endocarditis, who was admitted 15 months after neurosurgical treatment of disruption of cerebral aneurysm. The diagnosis of organic heart disease had been established in her childhood. 6 months after discharge from neurosurgery she developed marked dyspnoea on exertion and became febrile (up to 39.0 C). The presumptive diagnosis of infective endocarditis was established 6 months later, when she developed the symptoms and signs of severe anaemia with ESR 170 mm/hr although blood cultures were negative. The patient underwent treatment with Penicillin and Debecillin. On admission to our Institute echocardiography showed a very large, mobile vegetation in the left ventricle, connected to the anterior leaflet of mitral valve. Decision of mitral valve replacement was made, but rupture of the next cerebral aneurysm was the reason of unexpected, sudden death of the patient. The postmortem examination revealed 7 x 4 cm large vegetation, with the mass of 7.0 g. Histologically the vegetation consisted of mass of fibrin strands, platelets and blood cell with inflammatory cells. On its base the signs of the process of organization were marked. This vegetation was the largest one that we found in literature on this subject.

Disorders of the heart frequently cause pulmonary dysfunction because of the close structural and functional association of the heart and lungs. The pulmonary vasculature is very commonly affected by cardiac pathology. The pulmonary vasculature is normally a low-pressure, low-resistance circuit with high compliance and tremendous vascular reserve. Although resting vascular tone is low, there are many identified mediators of pulmonary arterial tone that may help mediate pulmonary blood flow. Alveolar hypoxia is clearly a stimulus for increasing pulmonary vascular resistance although factors that mediate the response to hypoxia are not fully understood. Patients with left-to-right shunting due to congenital heart disease because of elevations in pulmonary artery flow and pressure tend to develop progressive anatomic changes in the pulmonary vasculature. This leads to an increase in pulmonary vascular resistance, irreversible pulmonary hypertension, right heart failure, reversal of shunt flow, and Eisenmenger's syndrome. The degree of anatomic vascular damage due to left-to-right shunting can be graded histologically. Lesser grades of damage are reversible with corrective surgery, whereas more severe grades show no improvement or progression with operation. Chronic left-sided congestive heart failure seen in rheumatic mitral stenosis can cause secondary changes in the pulmonary vasculature. Pulmonary hypertension and increased pulmonary vascular resistance can increase reflexly and form a "second stenosis" that further limits cardiac output. Unlike congenital heart disease, severe grades of pulmonary arterial damage are not seen in left heart failure from mitral stenosis or other causes, and consequently with surgical correction pulmonary hypertension reverses. Pulmonary function testing is adversely affected by congestive heart failure. Both restrictive (stiff lungs) and obstructive (cardiac asthma) defects are observed in congestive heart failure. DLCO is abnormally decreased. With treatment of heart failure these defects reverse. Both elevated systemic and pulmonary venous pressures affect fluid filtration in the pleural space and cause pleural fluid accumulation. The fluid is transudative with low protein, low lactate dehydrogenase, and low cell counts. Transudative effusions from heart failure resolve with treatment. With large effusions and cardiomegaly, pulmonary dysfunction results because of atelectasis from compression and space-occupying effects of the heart and pleural fluid. Following myocardial infarction, cardiac surgery, or other cardiac trauma, the postcardiac injury syndrome can result. The syndrome is characterized by exudative pleural and pericardial effusions along with pulmonary infiltrates, fever, chest pain, leukocytosis, and an elevated ESR. The syndrome must be diagnosed by exclusion of bacterial pneumonia, pulmonary emboli, and congestive heart failure. Treatment is with nonsteroidal anti-inflammatory agents or systemic co

The authors describe 3 cases of left atrial myxoma confirmed by two-dimensional echocardiography and at operation. One patient had the symptoms of embolisms to the cerebral and renal vessels in the absence of heart disease, 2 patients presented with the symptoms of congestive heart failure. In one patient, loud first sound as well as systolic and diastolic murmur at the heart apex were documented. The nonspecific manifestations (weight loss, fever, high ESR, dysproteinemia, and rheumatoid factor) were observed in all the cases. The difficulties encountered in the clinical diagnosis of heart myxoma are discussed. The differential diagnosis is made between valvular heart disease and infective endocarditis, systemic vasculitis, cardiomyopathy, etc. Echocardiography to exclude myxoma should be performed in patients with thromboembolism, rheumatic valvular disease, subacute endocarditis (particularly in the absence of the classical symptoms) and in those with fever of unknown origin.

Sixty-seven patients with brain abscess were managed over 19 years (1975-1993). Our series had a 2.5 to 1 male predominance; the age distribution was from 3 days to 81 years. The underlying conditions of hematogenic brain abscesses (n = 33; 49%) included lung infections (n = 16), heart disease (n = 4), sepsis (n = 10), and other foci (n = 3). Otolaryngologic infections led to the abscess in 10 cases; there were 9 traumatic abscesses. The causes remained unknown in 15 cases. There were 47 solitary abscesses (70%) and 20 multiple abscesses. The most frequent presenting signs and symptoms were neurologic deficits (n = 17), disturbances of consciousness (n = 14), seizures (n = 6), and headaches, meningism and vomiting (n = 13). Causative organisms were isolated in 39 cases (58%) and included staphylococci (n = 6), streptococci (n = 6), enterobacteriae (n = 2), and anaerobic pathogens (n = 9). The most reliable laboratory sign of inflammation was an elevated ESR (52/59 patients). With the advent of computed tomography, burr hole aspiration of the abscess with or without drainage was possible in 30 cases; the mortality in this subgroup was 9%. All 4 patients with surgical excision in the pre CT-era died. The mortality of patients treated with antibiotics only was 62% (18/29). Overall mortality was 37% (25/67), including 5 cases with post mortem-diagnosis of brain abscess. Good recovery was achieved in 29/42 survivors. Predictors of a poor outcome were the patient's age, the level of consciousness, multiple abscesses, polybacterial cultures, and a hematogenic etiology, but not the size of the abscess.

Underlying diseases, complications, clinical findings, and laboratory findings were evaluated in 158 cases of septicaemia admitted to Jikei University Hospital from 1975 to 1994, in order to conjectured factors that prescribe for the prognosis. 50% of the patients had underlying diseases. Malignancy including leukaemia (31 cases, 39.2%) was the most common underlying disease, followed by low birth weight infant (17 cases, 21.5%), aplastic anemia (9 case, 11.4%), and congenital heart disease (7 cases, 8.9%). The death rate for patients with underlying disease (27.8%) was significantly greater than the mortality for normal patients with septicaemia (8.9%) (p < 0.05). Meningitis (24.7%) was the most common complication, followed by DIC (19.6%), shock (15.2%), and pneumonia (10.8%). The mortality rate of septicaemia complicated by shock was 66.7% (p < 0.01), and that complicated by DIC was 45.2% (p < 0.01). The mortality rate for patients with the clinical findings of respiratory distress, cough, abdominal distention, cyanosis, splenomegaly, or peripheral coldness was more than 40% and significantly greater (p < 0.01). Mortality rate in patients with granulocyte counts of < 4.000/mm3, platelet counts of < 5 x 10(4)/ mm3, total protein of < 5.0 g/dl, or ESR of < 20 mm/hr were significantly greater (p < 0.01) than those in patients with normal laboratory findings. Coincidence rate of blood and stool cultures was 57.9% for E. coli, and 28.6% for Klebsiella sp., and that of blood and throat cultures was more than 30% for Pseudomonas sp., Haemophilus influenzae, and Staphylococcus aureus. In the study of antimicrobial susceptibility for microorganisms isolated, the number of drug resistant S. aureus had increased in the last 10 years.

Heart failure (HF) is a complex clinical syndrome due to ischaemic heart disease, idiopathic cardiomyopathy, hypertension, valve heart disease and others. It is not clear if the etiology of HF influences decreased in this syndrome exercise tolerance. Controversial is also dependence of cytokine levels on etiology of HF. The aim of the study was to compare exercise capacity and cytokines levels in pts with ischaemic and dilated cardiomyopathy. We analyzed circulating levels of TNF-alpha and its soluble receptors sTNF-RI and sTNF-RII, and interleukin-1beta (IL-1beta), and interleukin-6 (IL-6) in 41 pts with CHF, functional class NYHA I-IV, mean EF--25.2 +/- 7.1%. For determination of cytokines level (using R & D System tests) venous blood was withdrawn after 30 minutes of supine rest. All underwent echocardiography and cardiopulmonary exercise stress testing. Dilated cardiomyopathy (DCM) was diagnosed in 21 pts, ischaemic (ICM) in 20 pts. Pts with DCM were younger then with ICM (48 +/- 6.6 vs 56 +/- 6.6 yrs; p = 0.001). There were no significant differences between groups concerning BMI and EF. There were no significant differences in the level of TNF-alpha and sTNF-RI between groups. There was a trend of increased sTNF-RII in pts with ICM (3179.7 +/- 832.7 vs 2699 +/- 680.1 pg/ml; p = 0,07), IL-1beta (2.55 +/- 2.41 vs 1.49 +/- 1.68 pg/ml; p = 0.087) and IL-6 (6.25 +/- 2.21 vs 4.98 +/- 3.64 pg/ml; p = 0.065), and significant increased ESR (11.2 +/- 9.5 vs 5.5 +/- 4.7 mm/h; p = 0.04). Peak VO2 was reduced in pts with ICM group as compared to those with DCM (14.1 +/- 3.7 vs 18.1 +/- 4.8 ml/kg/min; p = 0.0069). In chronic heart failure circulating levels of cytokines tended to be higher in pts with ischaemic origin of the syndrome. The exercise capacity is lower in ischaemic cardiomyopathy.

This prospective study was undertaken in Dhaka Shishu Hospital from 15th March 2005 to 15th October 2006 to determine the role of micro-ESR and immature and total neutrophil (I/T) ratio in early diagnosis of neonatal septicaemia. Eighty suspected cases of septicaemia admitted in neonatal ward of Dhaka Shishu Hospital were included in this study. Patients those who had history of perinatal asphyxia, infant of diabetic mother, congenital cyanotic heart disease etc. were excluded from the study. Thirty neonates without sign symptoms of septicaemia admitted for other causes like jaundice, feeding problems etc. were taken as a control group. After taking informed consent data were collected in structured questionnaire. Following hematological investigations like total WBC count, differential count, absolute neutrophil count, band cell count, platelet count, CRP, blood culture were done. Micro-ESR was done as bed side test. I/T ratio detected from total neutrophil and band form count. Patients with positive blood culture were categorized as definite sepsis. Patients with negative blood culture but abnormal hematological report suggestive of sepsis were categorized as probable sepsis. Those who had no signs of sepsis were categorized as control group. Micro-ESR more than age of the patient in days+3 mm in 1st hour were considered significant for sepsis. I/T ratio more than 0.2 was considered positive for sepsis. Sensitivity and specificity of micro-ESR was 63.3% and 60% respectively. Sensitivity and specificity of I/T ratio was 70% and 56% respectively. Combination of micro-ESR and I/T ratio showed high sensitivity (80%) and specificity (70%).

This prospective study was undertaken in Dhaka Shishu Hospital from 15th March 2005 to 15th October 2006 to evaluate the role of simple hematological test for early diagnosis of neonatal sepsis. Eighty suspected cases of septicaemia admitted in neonatal ward of Dhaka Shishu Hospital were included in this study. Patients those who had history of perinatal asphyxia, infant of diabetic mother, congenital cyanotic heart disease etc. were excluded from the study. Thirty neonates without sign symptoms of septicaemia admitted for other causes like jaundice, feeding problems etc. were taken as a control group. After taking informed consent data were collected in structured questionnaire. Following laboratory investigations like total WBC count, differential count, absolute neutrophil count, band cell count, platelet count, CRP, blood culture were done. Micro-ESR was done as bed side test. Immature and total neutrophil ratio (I/T ratio) detected from total neutrophil and band form count. Patients with positive blood culture were categorized as definite sepsis. Patients with negative blood culture but abnormal hematological report suggestive of sepsis were categorized as probable sepsis. Those who had no signs of sepsis were categorized as control group. Absolute neutrophil count (ANC) had low sensitivity (13%) but Micro-ESR, CRP, I/T ratio, platelet count had moderately high sensitivity and specificity. These simple hematological screen are useful marker for early diagnosis of neonatal sepsis.
