Blood pressure should be routinely measured in all infants and children. Measurements should be performed with an appropriate size cuff and observed pressures compared to normal values for age. Elevated blood pressure is seen in one to ten percent of children, depending on the age group surveyed and the definition of hypertension selected. Thirty to fifty percent of children with elevated blood pressures are asymptomatic. The remainder have symptoms which are nonspecific, including headaches, visual disturbances, seizures, congestive heart failure, and facial palsy. Hypertension in children, unlike hypertension in the adult, usually has a definite cause which often responds to adequate medical and/or surgical treatment. For this reason, children with well-confirmed hypertension should be thoroughly evaluated. The most common causes of hypertension found in children are renal disease (pyelonephritis, vascular disease, structural malformations) and coarctation of the aorta. An approach to the child with transient or persistent hypertension is described. Diagnostic studies should be individualized and should follow clinical clues where possible. Medical management of the child with acute hypertension is discussed.

The clinical and hematological features of 100 patients with sickle cell anemia are reviewed. The heart was enlarged and a murmur was heard in nearly 80 percent of patients. Pneumonia and pulmonary infarction occurred in 43 percent and 12 percent of patients, respectively. Musculoskeletal involvement included the hand-foot syndrome (15 percent), leg ulcers (55 percent), aseptic necrosis ofbone (11 percent), and osteomyelitis (4 percent). Symptoms and signs related to the gastrointestinal system included jaundice (55 percent), hepatomegaly (50 percent), splenomegaly (23 percent), hepatitis (11 percent) and gallstones (9 percent). Three patients underwent cholecystectomy and three patients had their spleens removed. Pyelonephritis occurred in 17 patients, priapism in five and hematuria in seven. Nineteen women had 39 pregnancies, of which 35 resulted in the birth of healthy infants. At least 328 painful crises occurred in 73 patients. There were also 13 hemolytic crises, eight sequestration crises, and five aplastic crises. A trail of alkali therapy in 33 crises in children failed to produce beneficial effects greater than hydration and analgesics alone as used in the control group. Laboratory findings in the 100 patients were comparable to those previously reported in the literature. The renal concentrating defect in most patients was confirmed. There were six deaths: hepatic coma secondary to post-transfusion hepatitis, thrombosis of inferior vena cava, congestive heart failure, exsanguination from erosion of the pancreaticoduodenal artery, extensive bronchopneumonia, and pulmonary infarction.

Renal replacement therapy (RRT) for Brazilian children with uraemia has been utilized since 1970 in the state of Rio Grande do Sul. One hundred and eighty patients receiving this therapy between 1970 and 1988 have been reviewed. The annual acceptance rate of new paediatric patients in this period increased from 0.6 to 6.5 patients per million child population. Glomerulonephritis (36.1%) and pyelonephritis including urological anomalies (31.7%) were the most frequent causes of end-stage renal disease. Outpatient hospital haemodialysis was the primary form of dialytic treatment in patients 5-15 years of age. Continuous ambulatory peritoneal dialysis was more often used in patients less than 5 years of age. The survival after 1 year on dialysis was 79.9% for children aged 5-15 years starting dialysis during the period 1985-1988. Fluid overload with congestive heart failure and infection were the main causes of death in children on dialysis. Eighty-four children received 93 grafts; only 14 (15%) were from cadaveric donors. One-year patient and graft survival of first living-related donor transplants were 92.2% and 78.5% respectively during the period 1985-1988. Infection accounted for 43.5% of deaths after transplantation. We conclude that RRT is becoming increasingly successful for children in our region but that greater emphasis upon patient compliance with all forms of RRT and upon cadaver kidney donation is needed.

We present a post-mortem examination of two hearts in which we found organized mural thrombi attached to the right atrial endocardium in the recess called antrum atrii dextri. This region is a place where the sinus node is situated very close to the endocardium of right atrium. Any pathological process involving the node (inflammation, degeneration) may reach this part of endocardium by continuity, this in turn creates convenient conditions for mural thrombi formation. The first case--a 52-year old man who died of severe congestive heart failure caused by rheumatic disease with mitral and aortic stenosis. Atrial fibrillation had developed several years before his death. Apart from typical changes of mitral and aortic valves a post-mortem examination revealed an organized, globular thrombus in antrum atrii dextri. In the microscopical findings of the sino-atrial region the fatty degeneration of the sinus node with multiple mononuclear cell infiltration was the most striking feature. The sinus node artery was narrowed due to fibro-muscular dysplasia of its wall. The second case--a 74-years old man who suffered from arterial hypertension and chronic pyelonephritis with a history of heart infarct in the past. The ECG recording showed multifocal atrial rythm with variable P wave morphology and P-Q distance. At necropsy the whole heart was significantly enlarged with no scars or any other signs of healed infarct. The microscopical findings revealed the heart muscle to be infiltrated by amyloid deposits particularly apparent in the sinus node. Similar thrombus of 1.5 cm in diameter was found in antrum of the right atrium.(ABSTRACT TRUNCATED AT 250 WORDS)

The frequency and degree of circulatory insufficiency depending on the stage of the disease are analyzed in 404 patients with chronic glomerulonephritis and 145 patients with chronic pyelonephritis aged 15 to 74 years. When the renal function is still preserved different degrees of circulatory insufficiency are diagnosed in 29.4% of patients. Circulatory insufficiency complicates more often chronic glomerulonephritis than pyelonephritis and is more common in the aged. Latent cardiac insufficiency is more common. In the period of chronic renal insufficiency cardiac decompensation is seen in 78.1% of cases, its frequency is practically the same in glomerulonephritis and pyelonephritis. The mechanisms of development of cardiac insufficiency and the principles of treatment depending on the functional state of the kidneys are discussed.

Macroscopic and histological studies of 3000 consecutive autopsies (43.9% of the registered deaths) were performed by the same pathologist in a geriatric institution over a period of 20 years. Bronchopneumonia (42.9%), malignant neoplasms--mainly of the gastrointestinal tract and its annexae and the lungs (28.1%)-pulmonary thrombo-embolism (21.2%) and acute myocardial infarction (19.6%), were the most prevalent fatal conditions observed. Next, in decreasing order were: urinary tract infection (12.3%), acute cerebrovascular disease (6.5%), internal haemorrhage (5.5%), and congestive cardiac failure (3.3%). Some "rare" causes of death noted included trauma, metabolic disease, acute asphyxia from foreign body obstruction of the upper respiratory tract and degenerative neurological diseases. Some potentially treatable disorders which led to death were unsuspected clinically: for example, acute pyelonephritis (87%), pulmonary thrombo-embolism (74%), acute myocardial infarction (74%) and active pulmonary tuberculosis (61%). With advancing age there is an increased frequency of multiple pathological processes in a given subject and interactions play an important role in morbidity and mortality. We observed that two or more co-existing conditions often determine the fatal event. We also emphasize the relevance of post-mortem examination to prevention of disease and to therapeutic medicine in a hospitalized geriatric setting.

Kidneys from 74 consecutively autopsied primarily non-insulin-dependent diabetes cases and 59 age-, sex-, and ethnic group-matched controls were examined qualitatively and semiquantitatively to determine whether focal mesangiolyses (FMs), Kimmelstiel-Wilson (KW) nodules, and glomerular capillary microaneurysms (GCMs) were related lesions, to determine their extent and pathogenic sequence, and to look for associations with structural and functional factors. Light microscopic examination of serial sections, immunohistochemical stains, image analysis, and electron microscopy were used. Focal mesangiolyses, KW nodules, and GCMs occurred in 31 of the 74 diabetes cases (27 had FMs, 29 had KW nodules, and nine had GCMs) and were positively correlated with each other semiquantitatively (r = .71, .70, and .68, respectively). Numerous FMs were found, involving 62% and 78% of the glomeruli in the two most severely affected cases. Most FMs were located at the periphery of KW nodules, but de novo FMs were documented in six cases. Glomerular capillary microaneurysms were deemed occasional complications of FMs because they were much less common, and 25 of the 27 GCMs identified were contiguous with FMs. Focal mesangiolyses and GCMs were deemed transient lesions, being absent in end-stage kidneys. Both FMs and KW nodules consisted of a spectrum of lesions. For the sake of clarity they were arbitrarily divided into two types: edematous and proliferative FMs and simple and complicated KW nodules. Their characteristics suggested the following pathogenic sequence: edematous FM-->proliferative FM-->focal nodular mesangial expansion-->simple KW nodule-->recurrent FM-->complicated KW nodule. Complicated nodules were associated with marked alterations in the lobular capillary. The number of mesangial cells was increased in FMs and they were thought to be responsible for increased matrix production. Focal mesangiolyses and KW nodules were positively associated with diabetes, proteinuria, and hyalinization of afferent and efferent arterioles, but were weakly or not associated with hypertension, arcuate and interlobular artery stenosis, hydroenphrosis, acute pyelonephritis, renal arterial atheromatous emboli, glomerular platelet-fibrin thromboemboli, and congestive heart failure.

60 cases of endotoxic shock in obstetrics and gynecology in a 7 year period, January 1974 to December 1980 in Nigeria are reviewed. The most common and causative conditions were septic abortion, puerperal sepsis and pyelonephritis in pregnancy. The commonest cultured organism was Eschericha Coli. There were 33 deaths, giving a mortality rate of 55%, which falls within the range reported in the literature. The mortality rate in the institution where this study was conducted has shown a downward trend. Early surgery is advocated in those cases with infected retained products of conception and pyoperitoneum, and more liberal use of steroids, hypertonic glucose solution and digoxin, especially in patients with cardiac decompensation. The patients of the sample met the following criteria: 1) the occurrence of hypotension with consistent reading of 80/50 mm Hg or less; 2) demonstrable evidence of infection as determined by fever, hematological and bacteriological studies; and 3) the presence of persistent tachycardia. Conditions related to pregnancy accounted for 50% of of all cases. A significant finding was that 14 out of 18 patients with induced abortion had it at 2 weeks before admission. A majority of the patients in this study had subnormal temperature. The presence of jaundice, pneumonia, persistent oliguria and hepatomegaly are ominous signs accompanied by high mortality. Pulmonary factors in shock are important in determining patient survival as well as lung functions afterwards. The mortality in endotoxic shock remains high despite widespread use of fluids, antibiotic and steroid therapy, indicating that eliminating bacteria and restoring blood pressure are not the only considerations in treating shock. Insufficient nutrition may contribute to cardiorespiratory deterioration in the acutely ill patient; important physiological variables are improved by administration of hypertonic glucose solution, which leads to increased clearance of E. Coli from the blood.

This study compared the management, prognostic factors and outcomes of patients with emphysematous pyelonephritis (EPN). Twenty-one patients with EPN were studied between September 1996 and August 2005, and were assigned to two groups. Patients in Group 1 received conservative treatment with/without percutaneous catheter drainage (PCD) while patients in Group 2 underwent nephrectomy following medical treatment and PCD. A post hoc analysis of the prognostic factors was performed between survivors and nonsurvivors, and between the survivors in Group 1 and Group 2. There were 14 patients in Group 1, and seven in Group 2. The mortality in Group 1 was 35.7% (5/14) and in Group 2 was 0% (p = 0.12). There were no statistically significant differences in prognostic factors between the two groups, though patients in Group 1 had relatively lower platelet counts (p = 0.07) and Group 2 patients had a higher incidence of dialysis after nephrectomy (p = 0.03). Comparing the survivors and nonsurvivors, patients with comorbid congestive heart failure and patients initially presenting with consciousness disturbances had higher mortalities (p = 0.02 and p < 0.01, respectively). Nonsurvivors also had lower platelet counts (p = 0.06). In conclusion, medical treatment with/without PCD can be used to manage patients with EPN. More agressive drainage is needed in patients with congestive heart failure who initially present with consciousness disturbances or thrombocytopenia.

We report a case of ventricular septal defect (VSD) associated with infective endocarditis complication of aortic and pulmonary valvular regurgitation. He received treatment for pyelonephritis and after 2 months he was suffering from congestive heart failure. Echocardiography showed vegetation on the aortic valve and the anterior semilunar cusp of the pulmonary valve. He was referred to our department for surgical repair. Aortic valvular replacement, pulmonary valvular repair and direct closure of VSD were performed. The postoperative course was uneventful and the patient discharged at 28 postoperative day.
