An analysis was performed of history, course of pregnancy, parturition, and condition of the newborn babies in female patients with pyelonephritis depending on the microbiological factor and environmental situation in the zone of residence. The pregnant women living under adverse environmental conditions display high levels of endocrine, cardiovascular, gastrointestinal disorders, and of tonsillitis. In the majority of cases, pregnancy is noted to be complicated by anemia (76.7%) and fetoplacental incompetence (62.9%), with infants being born in asphyxia presenting with signs of hypotrophy, congenital infection. Of the above infants, 37% develop postnatal inflammatory conditions. Two variants were shown to play a part in the etiology of pyelonephritis: monoetiological one marked by predominance of Staphylococcus aureus and Escherichia coli and polyetiological variant characterized by predominance of Candida fungi, Staphylococcus aureus, and mycoplasma. Irrespective of the microbiological factor, the female patients with pyelonephritis demonstrated high levels of premature birth, had a history of infertility, and were presenting with genital and extragenital pathologies.

The aim of the present study is to investigate the pathophysiological characteristics of a number of recent cases of malignant hypertension (MHT) and to compare them to the characteristics of earlier cases. Patients with MHT (age 25-76, mean 44+/-2 years) who were admitted to our hospital from 1984-1999 were retrospectively studied. All of the patients had either grade III or IV retinopathy and diastolic blood pressure levels higher than 120 mmHg. The observations in this study were compared to previously reported findings regarding 59 MHT patients who were admitted from 1971-1983. Of the 37 recent MHT patients, 20 had essential hypertension (EHT) as the underlying disease, 13 had chronic glomerulonephritis (CGN), and the remaining 4 presented with other diseases including pyelonephritis and renovascular hypertension. A positive family history of hypertension was more prevalent in the EHT patients than in other patients, and persistent proteinuria, microhematuria, and anemia were more prevalent in the CGN patients. These characteristics were similar between the recent and previous cases. Within 4 weeks after admission, hemodialysis was initiated in 3 of the 13 patients (23%) with CGN and 2 of the 20 (10%) patients with EHT. The prevalence of renal death at 1 year after admission was 30%, which was lower than the prevalence in the previous cases (42%). Grade IV retinopathy was seen in 45% of the patients admitted from 1984-1999, significantly less than in the patients admitted from 1971-1983 (66%, p<0.05). In addition, left ventricular hypertrophy was less frequently observed on electrocardiogram in the recent cases (67%) than in the previous cases (88%, p<0.05). Our results suggest that the recent cases of MHT demonstrate less severe organ damage.

In the group of 289 pregnant diabetic women hospitalised and followed-up between 1991-2000 in the Maternal-Fetal Medicine Dept., Research Institute Polish Mothers Memorial Hospital, 44 patients were diagnosed with hypertension arterialis (15.2%), significantly more frequently in women with long lasting diabetes complicated by angiopathy and whose who trend to be obese. Metabolic control did not differ in the group with hypertension and without. In the group of pregnant women with hypertension following symptoms occurred significantly more frequently: proteinuria (29.5%), pyelonephritis (11.4%), anaemia (25%) and the risk of premature delivery (25%). Hypertension arterialis shortened significantly the duration of pregnancy (34.7 weeks of gestation vs. 37.3) and affected the obstetrical outcome such as:-low birth weight and longer time of newborn hospitalisation.

The incidence of asymptomatic bacteriuria is reported as 2-14% during pregnancy. Fetal and maternal complications like acute pyelonephritis, hypertension, anemia, preterm labor, low-birth-weight infants and intrauterine growth retardation can be expected. The purpose of this study was to determine the incidence of asymptomatic bacteriuria during pregnancy and its relation to pregnancy complications. The study involved 270 pregnant women up to 32 gestational weeks during a 9-month period. At the initial visit, they were screened with urine culture in order to detect asymptomatic bacteriuria. A control group was formed in a retrospective manner from the first day of the study with 186 pregnant women who delivered in our clinic and who were not screened for asymptomatic bacteriuria. The incidence of asymptomatic bacteriuria was 9.31%. Escherichia coli accounted for 79%, which was the most frequent of the isolates. We observed recurrence and had to apply treatment again to 21.7% of the women. The sensitivity, specificity, positive predictive and negative predictive values of leucocyturia as a screening test for asymptomatic bacteriuria were 91.3%, 83.6%, 45.6% and 98.5%, respectively. We diagnosed preterm labor in six of 23 (26%) with asymptomatic bacteriuria and 16 in 163 (9.3%) women in the urine culture negative group. The ratio acute pyelonephritis in the group which was routinely screened and treated for asymtomatic bacteriuria was 0.5% while the prevalence was 2.1% in the nonscreened group. Considering the relatively high incidence of asymptomatic bacteriuria during pregnancy and the relevant complications, we propose to screen and treat asymptomatic bacteriuria routinely in all pregnant women.

We reviewed 43 adult kidney transplant patients (32 males and 11 females, 14-68 years of age) performed at our center between July 1999 and February 2002. Donors (39 males and 4 females) comprised two cadaverics, five living-related and 36 living-unrelated; age 18-44 years. Indications for kidney transplantation (KT) were: chronic glomerulonephritis (8), re-transplantation (4) and chronic pyelonephritis (3); kidney disease was unknown in 15 cases. ATG-F was given as a single intra-operative bolus induction therapy in 26 patients; extended ATG-F dose was given in 17 patients because of a high sensitization status, slow graft function (SGF) or development of calcineurin inhibitors toxicity. ATG-F was stopped in seven out of 17 patients because of thrombocytopenia or severe anemia. ATG-F-related fever occurred in six patients. Acute rejection (AR) occurred in eight patients (18%) 5-11 days post-KT. ATG-F was given in three steroid-resistant AR. Infection occurred in 19 patients (44%) for a total of 32 infectious episodes comprising 24 bacterial infections (nine urinary, seven catheter-related and three respiratory), six viral infections (five CMV and one herpes) and two fungal infections (one pulmonary aspergillosis and one catheter-related candidiasis). The hospital stay was 8-75 days for a median of 13 days. The mean serum creatinine upon discharge, at 1 and 6 months after KT were: 2.04+/-0.37, 1.43+/-0.16 and 1.29+/-0.08, respectively. One patient lost his graft on day 9 because of graft microthrombi related to Factor V-Leiden mutation. The 6 months actuarial patient and graft survival were 100 and 97.6%, respectively. ATG-F as a bolus therapy is an effective and safe induction treatment in KT.

Xanthogranulomatous pyelonephritis is an uncommon disease in children. We report of a 2-month-old girl with urinary tract infection and with a renal mass detected by ultrasound scan. The preoperative differential diagnoses were Wilms tumor, multicystic dysplastic kidney, renal abscess, and mesoplastic nephroma. The subsequent histopathological findings allowed the diagnosis of xanthogranulomatous pyelonephritis (XGP). Although XGP is rare at this age, it must be considered in the differential diagnosis of a child presenting with renal mass, either with or without associated urolithiasis, anemia, and elevated inflammatory markers. The long-standing mainstay of therapy for diffuse XGP has been nephrectomy. However, we report the successful preservation of renal mass with partial nephrectomy for diffuse XGP. The affected kidney grew normally and preserved residual function after the operation. Hence we strongly suggest parenchymal saving in pediatric cases of XGP to preserve renal function.

Xanthogranulomatous pyelonephritis is a rare disease in childhood. Because the symptoms and signs are chronic and non-specific, preoperative diagnosis is usually difficult. We report an 8-year-old boy who had an abdominal mass and anemia for more than 6 months. Fever and dyspnea occurred 4 days prior to admission. Ultrasonography revealed an enlarged right kidney with multiple parenchymal hypoechogenic areas, absence of normal parenchymal structures, and perinephric thickening with multiple calcifications. An abdominal computed tomogram demonstrated an irregular, enlarged right kidney with multiple low-density round areas consistent with hydronephrosis and calculi. Diminished excretion of contrast media and a severe perinephric inflammatory reaction were present. Poor right kidney function was demonstrated by Tc99m-diethylenetriamine penta-acetic acid split renal function examination. We diagnosed xanthogranulomatous pyelonephritis preoperatively based on the clinical and radiological features. The child first had drainage of an extrarenal abscess and antibiotic therapy, followed by definitive nephrectomy. The hospital course was complicated with pleural effusion, peritonitis, pelvic abscess, and sepsis. A two-stage nephrectomy requiring less radical resection and decreasing the surgical complications would have been preferable.

Pregnancy in SCD women, with a major sickle cell syndrome, is a high-risk situation and is associated with raised incidence of maternal and fetal morbidity and mortality, mainly in late pregnancy, during delivery and in the postpartal periods. Pregnancy increases the incidence of sickle cell specific complications such as anaemia, vaso-occlusive crisis, abdominal, pulmonary (acute chest syndrome) or placental thrombosis, infections (urinary tract infection, pyelonephritis, pneumonia), and toxemia. Maternal death can occur. Sickle cell disease is responsible for high risk of spontaneous abortion, intra-uterine growth retardation, intra-uterine fetal death, preterm delivery, and perinatal mortality related to hypoxemia and placental thrombosis. More and more sickle cell affected women reach adulthood and reproductive age (fertility of sickle cell women is normal). The knowledge of these risks has contributed to the implementation of specific management program and to a better outcome of pregnancy. Such a program includes a close multidisciplinary approach for the duration of the pregnancy, the delivery and the postpartal period, in tertiary maternal health services level. Blood transfusion depends on teams and is related to strictly restricted maternal, obstetrical and hematologic indications.

A 37-year-old woman with a personal history of appendicectomy, cholecystectomy, left oophorectomy secondary to an ovarian cyst complication, nephritic colic with repeated episodes of pyelonephritis, alcoholic hepatopathy, Raynaud's phenomenon and bilateral exophthalmos showed an increase in volume in the root of the upper limbs and in the base of the neck over a period of 4 years, painful to the touch and of a soft consistency. She presented with a pseudo-athletic appearance (Fig. 1) produced by an increase in the volume at the root of the upper limbs, upper back and the back of the neck (Fig. 2). The lesions produced a pulling sensation and were associated with paresthesia, hyperesthesia, and a moderate loss of strength in both arms. A biopsy taken from the upper third of the right arm showed a diffuse proliferation of the subcutaneous adipose tissue, which appeared normal, and extended between the collagen fibers, reaching in some cases into the most superficial zones of the reticular dermis (Fig. 3). Laboratory evaluation revealed a chronic anemia, leukopenia with moderate lymphopenia, increased erythrocyte sedimentation rate, elevation of enzymes of hepatic function, decrease in total proteins, and increase in ferritin, all in the context of hepatopathy. Antinuclear antibodies and the hormonal profile were normal. Abdominal and gynecologic echography revealed a right ovarian cyst of no clinical relevance. Cranial nuclear magnetic resonance (NMR) revealed an increase in the periorbital fat responsible for bilateral exophthalmos.

"Watermelon stomach" is a common name for gastric antral vascular ectasia (GAVE syndrome). This endoscopic finding is characterized by the appearance of parallel longitudinal red columns along mucosal folds, along with capillars dilatation and hemorrhagy. Finding reliable method for its recognition is of paramount importance. Patient B.D., a 54-year-old woman, developed renal failure, which led to hemodialysis treatment, on the basis of pyelonephritis chronica. As a consequence of the gastrointestinal bleeding, the patient had black stools and developed severe anemia. The endoscopic finding showed the existence of visible columns of vessels transversing the antrum in longitudinal folds and converging in the pylorus, with clear red spots and surrounding hyperemy covered by drops of fresh blood. The diagnosis of "watermelon stomach" was confirmed after the pathohistological examination of the tissue taken at the biopsy, followed by total gastrectomy. Postoperative status was normal, without gastrointestinal hemorrhagia, and she went on with hemodialysis. Before the surgery she received 105 blood transfusions, and after surgical treatment she has received only 18 so far. At the moment she is in good health condition, and on hemodialysis. The reason we have reported this case of "watermelon stomach" syndrome in patient with chronic renal failure is to indicate that this rare anomaly of gastric blood vessels can lead to gastrointestinal blood loss in these patients. Since it is often the reason for many wrong diagnoses, it should be also taken into consideration in cases like these.
