The results of treatment of iron deficiency anemia in 217 children and infants (aged 8 months to 12 years) with ferrosulfate serin complex are demonstrated: 208 children with simple iron deficiency anemia with hemoglobin 9.1 g/100 ml before treatment had in the first 4 weeks a daily increase of 0.082 g/10000 ml hemoglobin; in 3 children with severe anemia of chronic blood loss the daily increase was 0.21 mg/100 ml and in 6 children with hypoxic polycythemia with congenital heart disease and so called latent iron deficiency anemia the increse was 0.16 g/100 ml. Through the better absorption of this serin-ferrosulfate complex the required dosis is only 3 mg/kg/d. The benefit of this small dosis is the low rate of side effects.

Forty children with chronic renal failure (CRF) on conservative treatment, on hemodialysis, or after renal transplantation and 22 children respresenting a non-uremic control group were subjected to repeated cardiologic examinations by ECG, PCG, chest X-rays and cycle ergometer exercise tests to monitor signs of uremic heart disease and to evaluate physical working capacity (W170). In the CRF group a progressive impairment of W170 was found, starting at an early stage of the disease. Exercise tolerance was inversely related to the degree of CRF. A correlation was also found between W170 and renal anemia. After starting dialysis, W170 failed to increase significantly. Immediately after dialysis an acute drop in W170 occurred. Renal anemia was found to be the main pathogenetic factor of uremic heart disease in children. In some cases hypercirculation following arteriovenous fistulae became equally important as a cause of reduced myocardial performance. Physical rehabilitation, as measured by exercise tolerance tests, was better in transplanted than in dialysed children.

A study of 200 pregnant women at the State Zenana Hospital, Jaipur, was conducted to analyse the effects of various maternal diseases on neonates. The maternal diseases were anemia, hypertension, urinary tract infection, heart disease, and tuberculosis. 200 healthy pregnant women were studied as controls. A high incidence (64.3%) of low birth weight babies were born to the unhealthy mothers. 80% of the tubercular mothered babies weighed less than 2.5 kg; 70% of the heart disease; 65% urinary tract infections; 60% hypertensive; and 64.3% anemia. The abnormal newborns showed a smaller average length and smaller head circumference (less than 33 cm.) than the normal group. There was also higher incidence of prematurity and poor neurological status among the abnormal group. Congenital malformations accounted for 2.15% in the abnormal cases, compared to .5% in the control group. The morbidity rate was 85%, compared to 46% in the controls. The causes were conjunctivitis, diarrhea, and cord sepsis.

In this paper demographic characteristics, etiology, pathology and clinical features of infective endocarditis are reviewed simultaneous presentation of the data from our series of 50 cases with infective endocarditis. The peak incidence of infective endocarditis is between 11 and 15 years. Both sexes are equally affected. Patients with congenital or acquired heart disease tend to have hemodynamic trauma to the endocardium and vascular endothelium. These sites form the nidus for circulating bacteria of either spontaneous origin or the result of any oro-dental, genitourinary or other surgery or procedures and produce vegetations characteristic of infective endocarditis. The location of the vegetation is dependent upon the predisposing cardiac lesion. Embolic phenomenon is another cardinal feature of endocarditis and may occur in any organ system. Although a large variety of microbes have been known to cause endocarditis, streptococci and staphylococci remain the most frequent offenders. Clinical diagnosis of infective endocarditis is difficult because of the insidious onset and varied clinical features. A high degree of suspicion is essential for early diagnosis. Any patient with known heart disease and unexplained fever should be suspect for endocarditis. Splenomegaly, petechiae and embolic phenomena support this diagnosis. New or changing murmurs, splinter hemorrhages, Osler's nodes. Janeway's lesions and Roth's spots may be present. Elevated sedimentation rate, microscopic hematuria, leukocytosis with a shift-to-the-left and anemia may further support the diagnosis. Congenital or acquired heart disease and fever are all that will be present in many cases. Only isolation of the causative agent from the blood can confirm the diagnosis.

30 patients with tetralogy of Fallot were examined before and after correction. 10 of whom had previous procedures including 13 Blalock-Taussig shunts, 1 Cooley anastomosis and 6 pulmonary valvulotomies (Brock) with a dilator. Hemoglobin and blood gases were measured in 22 patients pre- and postoperatively on the 7th respectively 14th day and finally after 12 months. In 8 children the concentration of 2,3-DPG was accessed (pre-, postoperatively, immediately in ICU, on the 1st, 7th, 14th day and after 21 months). Hypoxia of various degrees was found at any time of the investigation, verified by a low venous oxygen saturation, high 2,3-DPG concentration and an erythrocytosis. The 2,3-DPG concentration was always elevated (preoperatively 18.2 +/- 1.8 muMol/g Hb; postoperatively 1st till 14th day 19.0 +/- 2.2; after 21 months 16.3 +/- 1.2 muMol/g Hb). Preoperatively hypoxia was correlated to the degree of the heart disease expressed by the hight of the Hb-concentration. In contrary after the correction signs of hypoxia (decreased venous oxygen saturation, increased 2,3 DPG-concentration) appeared with a low Hb as found in patients with anemia. The long term check-ups are indicative for slight cardiac residual disorders as there are hypoxic myocardial damage, residual gradients over the right ventricular outlet, reopened VSD's, and ventriculotomy scar tissue. Though the elevated 2,3-DPG-concentration and the consecutive rightward shift of the oxygen saturation curve obviously compensate these cardiac handi-caps as the excellent physical condition of the children shows.

According to data found in the literature, children born to epileptic mothers on anticonvulsant therapy have an increased perinatal mortality rate, namely 2-3 times the average. The congenital malformations attributed to anticonvulsant drugs cannot fully account for this high mortality rate. A case is described in which a severe bleeding disorder manifested itself in successive offspring. A discussion follows in which this defect in blood coagulation in the newborn and the role played by vitamin K is considered as representing an important and preventable cause of neonatal death and morbidity. Other features of the postnatal syndrome (CNS depression, congenital heart disease, withdrawal symptoms, anemia) are mentioned in the case report. Suggested preventative measures employing vitamin K, folic acid and vitamin D are briefly discussed.

Haemoglobin M is a rare cause of congenital cyanosis and is usually misdiagnosed as being due to congenital heart disease. This was also the case in a family on whom this report is based. In five members of three generations the characteristic grey-blue cyanosis was due to a haemoglobin M anomaly. In all of them cardiopulmonary disease, anaemia and haemolysis had been excluded. The amino-acid substitution was in the alpha-chain of the globin molecule. Consequently the carriers of the trait have an abnormal haemoglobin content of 20-25%. Despite marked cyanosis they feel well.

The signs that may arise after perinatal infection with human immunodeficiency virus type 1 (HIV-1) have been classified by the Centers for Disease Control, but the clinical usefulness of the classification system and the prognostic importance of each disease pattern have not been established. We sought to address these issues by analysing data from the Italian Register for HIV infection in children. We studied 1887 children born to HIV-1-seropositive mothers. 1045 were identified at birth and the others were registered later (median age 4.8 [range 0.4-72] months). HIV-1-associated signs developed in 433 (81.8%) of 529 seropositive infected children at a median age of 5 (0.03-84) months. These signs appeared significantly earlier in the 102 children who died of HIV-1-related illness than in those who are still alive (median 3 [0.03-55] vs 6 [0.03-84] months; p less than 0.001). The cumulative proportion surviving at age 9 years was 49.5% (95% confidence interval 27-65%) and the median survival time was 96.2 months. Separate analysis of the 112 seropositive infected children followed from birth and older than 15 months gave similar results. Hepatomegaly, splenomegaly, lymphadenopathy, parotitis, skin diseases, and recurrent respiratory tract infections formed the mildest disease pattern. Lymphoid interstitial pneumonitis and thrombocytopenia were signs of intermediate disease. By contrast, in multivariate analysis specific secondary infectious diseases, severe bacterial infections, progressive neurological disease, anaemia, and fever were significant and independent negative predictors of survival. Growth failure, persistent oral candidosis, hepatitis, and cardiopathy were associated in univariate analysis with significantly shorter survival. Our findings suggest that the outlook for children with perinatal HIV-1 infection is better than previously thought and that a new clinical staging system of single disease patterns is needed.

Thirty-one patients with chronic severe anemia of more than 3 months' duration (hemoglobin less than 7 gm/dl) and no underlying heart disease were studied by means of M-mode, two-dimensional, and Doppler echocardiography; an equal number of normal control subjects was also studied. There are conflicting reports regarding the influence of chronic severe anemia on systolic myocardial function, but diastolic function has not been systematically assessed. It is also uncertain whether anemia alone can cause heart failure in a structurally normal heart. We therefore performed a detailed study of echocardiographic indexes of systolic and diastolic left ventricular function in these patients. We found that patients with anemia have significantly faster heart rates and lower diastolic and mean blood pressures than normal subjects. They also have a significantly elevated cardiac output and stroke volume and larger left ventricles. Left ventricular contractility, assessed by the end-systolic stress-dimension relationship, was enhanced. There was no systematic evidence of diastolic dysfunction by Doppler assessment of mitral inflow. There was also no clinical evidence of congestive heart failure. We conclude that chronic severe anemia leads to a hyperdynamic state with systolic hyperfunction and no impairment of diastolic function. Anemia does not lead to congestive heart failure in the absence of underlying heart disease.

Pulmonary hemosiderosis (PH), a rare pathology, usually occurring during infancy and childhood, is characterized by numerous and repeated intra-alveolar bleedings, interstitial iron build-up with consequent progressive fibrosis and severe anemia. PH can be basically divided into 3 different categories: Primitive or idiopathic, involving a primitive deficit of antioxidizing enzymes in the erythrocytes in genetically predisposed subjects; Secondary, subsequent to chronic pneumopathy or cardiopathy; Associated with various pathologies including collagenopathies, glomerulonephritis, myocardiopathies, diabetes, steatorrhea, tireotossicosis. A particular type of Pulmonary Hemosiderosis, associated with allergy to cow's milk, has been described for the first time by Heiner. We present in this paper our personal experience of a young patient suffering from pulmonary hemosiderosis induced by cow's milk protein.
