In a racially mixed community in Gisborne, New Zealand, the prevalence of asymptomatic (covert) bacteriuria of pregnancy was 9.6%. The prevalence in Maori women was 17.1% and in non-Maori women 4.7%. There was a higher prevalence of bacteriuria in the younger women. Escherichia coli was the infecting organism in 58 of the 72 women with bacteriuria. Twenty-five (44%) of the E. coli were resistant to ampicillin and amoxycillin. Fifty-eight (81%) of the women with bacteriuria also had pyuria. In 37 of the 44 women (84%) who received antimicrobial therapy, the infection was cured. Single dose therapy was just as effective as a course of treatment. In 14 of the 28 untreated women, the infection cleared spontaneously. Four of the 28 (14%) patients in the untreated bacteriuric group developed acute pyelonephritis. More patients with bacteriuria had anaemia and a low fetal birth-weight.

Eleven children with xanthogranulomatous pyelonephritis are reported. The left side was affected in all patients. It is suggested that the diagnosis can be made pre-operatively. The condition is characterised by the fact that it is always unilateral and that renal calculi are found in a kidney with gross impairment of function; associated anaemia, leucocytosis and raised ESR are also present. The cause is unclear, but an obstructive element with infection is usually found.

Technical and maternal factors known to affect urinary estriol level or its measurement are discussed in view of the current use of serial estriol as an indicator of fetoplacental function. Technical artifacts can result from presence of methenamine mandelate, phenolphthalein, glucose, or high urine specific gravity. Aside from normal maternal factors such as inaccurate urine collection or variable fluid intake, estriol levels are depressed by corticosteroids and ampicillin. Pyelone phritis, anemia, hemoglobinopathy, abnormal renal status, malnutrition, and high altitude all depress estriol level or excretion. In some conditions such as pyelonephritis, amniotic estriol level may be a better indicator of fetal status.

Four pregnancies in three patients with spinal cord injury are presented. The major complications encountered include anemia, pyelonephritis, decubiti, premature labor, precipitate labor, and autonomic hyperreflexia. Autonomic hyperreflexia, a severe mass autonomic reflex response to labor, is associated with tachycardia, hypertension, headache, diaphoresis, and severe anxiety. It is probably due to increased norepinephrine release, as very high urinary metanephrines were measured in the latter two cases presented. Maternal and fetal physiology in labor are altered. Despite severe maternal and fetal stress responses, no fetal depression was observed.

Forty-three spinal cord injured patients with endstage renal disease (ESRD) maintained on hemodialysis were studied. The most prevalent renal lesions consisted of chronic pyelonephritis and amyloidosis while the main renal functional features included nephrotic range proteinuria, high urine output and relatively low serum creatinine for the degree of renal insufficiency. Normocytic, normochromic anemia with low reticulocyte response, low serum iron and iron binding capacity and high transfusion requirement and serum ferritin were noted. Various cardiovascular, pulmonary and gastrointestinal abnormalities were found with considerable frequencies. The incidence of amyloidosis was much higher than that reported previously. This is thought to be due to continued progression of amyloidosis occasioned by longer survival in the present series.

A black multipara was shown, by hemoglobin electrophoresis, to have hemoglobin SD disease. The patient exhibited a typically mild anemia that probably was secondary to folate and iron deficiencies as well as to hemoglobinopathic hemolysis. The course of her pregnancy was complicated by pyelonephritis and hyposthenuria, both of which have been reported in association with hemoglobin SD disease in pregnancy. The patient also was shown to have acute cholecystitis probably superimposed on a chronic cholelithiasis. This latter complication was probably the result of hemolysis due to hemoglobin SD disease. The patient was treated medically with good results, and, despite poor compliance and heroin addiction, delivered a viable infant at term.

To evaluate the impact of renal infection on pregnancy outcome, we studied a group of pregnant women with asymptomatic renal bacteriuria and another group who had acute pyelonephritis. In 248 women with asymptomatic bacteriuria, infection was localized by the antibody-coated bacteria method. These women were prospectively matched with abacteriuric control subjects and we found no adverse effects of treated renal or bladder infection. Specifically, the number of women with hypertension and anemia in each group was similar, and infants born to these women were comparable regarding perinatal mortality, mean gestational age, and birth weight, as well as indices of maturity. A total of 487 women with acute pyelonephritis were evaluated in a case-control study and observations of the correlation of maternal anemia and pyelonephritis were confirmed. Women with antepartum infection had no increased adverse perinatal outcome; however, in some women with intrapartum infection, pyelonephritis appeared to have initiated premature labor. We concluded that treated renal infection, whether symptomatic or asymptomatic, does not significantly modify pregnancy outcome.

99 patients with a chronic renal disease (glomerulonephritis, pyelonephritis, polycystic kidneys) with a GFR reduced to 2/3 normal and without anaemia were subjected to detailed haemodynamic investigation. The earliest haemodynamic abnormality was found even before the blood pressure became elevated. This consisted in a rise of the cardiac output. Ist most likely cause was an increase in the circulating blood volume. As the arteriolar and capacitance vessels adjusted to it, the blood pressure remained unchanged and the central venous pressure slightly decreased. Blood pressure rises, when this vascular adjustment subsides. At this moment the raised blood volume will drop to normal. These changes do not correlate with the minor fluctuations of the PRA which obviously are not responsible for the subsidance of the vascular adjustment and for the rise of blood pressure.

528 pregnancies of primiparous girls 13-17 years old who gave birth during 1988-90 at the obstetrical ward of the city of Pleven, Bulgaria, were evaluated. The pregnancy outcome and neonatal results were compared with those of 100 controls. These 528 births amounted to 5.48% of a total of 9635 births at the clinic. These girls were of low socioeconomic status, 14.2% were illiterate or had low educational attainment, and 56.42% were of Gypsy origin, without skills, and from rural areas. Only 32.89% of the Bulgarian girls had an official marriage license. Anemia was found in 13.64%, kidney infection (without symptoms of bacteriuria, pyelonephritis) in 6.44%, preeclampsia in 2.46%, and eclampsia in 0.76%. The most frequent occurrence was premature rupture of the membrane (9.85%). Term deliveries numbered 433 and preterm deliveries 95. There was a statistically significant difference between the two groups with respect to term and preterm deliveries (p 0.01). Dystocia amounted to 2.8% and instrumental delivery to 1.70% among these adolescent girls. The rate of premature delivery reached 17.99%, and cesarean section was performed in 5.44%. There was a significant difference between the two groups with respect to vaginal delivery (p 0.01) and cesarean section (p 0.01). 44% of 16-year old girls underwent cesarean section; and there was a significant difference in the rate of cesarean section between 14-year-old and 17-year-old girls (p 0.05) as well as between 16-year-old and 17-year-old girls (p 0.01). 71.95% of newborns had a birth weight of less than 3000 g. There was also a significant difference between the groups with regard to term and prematurely born neonates (p or = 0.01). Intrauterine growth retardation reached 2.46% because of the inadequate uterine size of girls 13-14 years old, insufficient weight gain during pregnancy (under 9 kg), and complications (preeclampsia and eclampsia). The rate of stillbirths was 7.63%, attributed to prematurity and malformation of the fetus. Maternal mortality reached 1.89% owing to pregnancy complications (eclampsia) among 17-year old girls because of low socioeconomic status and complete lack of prenatal care.

Four cases of diffuse xanthogranulomatous pyelonephritis (XPN) in young children are presented. In three patients the clinical picture was one of weight loss, anaemia and neutrophilia with a large renal mass. The fourth presented with haematuria. Ultrasound (US) and CT findings were almost identical in all four patients. US showed the affected kidney was massively enlarged but retained a reniform shape. Dilated fluid spaces containing calculi were present. CT confirmed the US findings and revealed peripheral enhancement without contrast excretion, with dilated calyceal spaces producing the "bear paw sign". Extrarenal extension into abdominal wall and psoas muscle is typical and was well demonstrated by CT. The affected kidneys were non-functioning and nephrectomy was required. Typical US and CT features allow a confident diagnosis of XPN and appropriate early treatment.
