The paper presents the data confirming the hypothesis on the involvement of the congenital enteroviral infection in etiology of chronic nephropathy manifesting in children in the presence of influenza-like and acute respiratory infections diseases. 100 relevant children were examined. Family history indicated a high risk of enteroviruses inheritance from mothers who were chronic carriers in 19 out of 20 children with pyelonephritis or interstitial nephritis (95%), in 17 out of 23 children with transitory nephropathy (73.9%) and 16 out of 57 patients without nephropathy (28.1%). Coxsackie enteroviruses (A and B) occurred in the urinary sediment in 82.3, 68.4, 29.5% of the patients from the groups under comparison, respectively. In children free of nephropathy the viruses manifested primarily in the seasons with the highest prevalence of the enteroviral diseases, in those with nephropathy Coxsackie viruses detection rate was not season-related. Recognition of enteroviruses (Coxsackie B, as a rule) was significantly related to the risk of the transmission from the mother. Persistence of the viruses in the cells of the urinary system of children with congenital viral infection seems to run subclinically for a long time. Influenza and other acute respiratory diseases promoted activation of the endogenic infection which resulted in transitory nephropathy or interstitial nephritides.

A 37-year-old female patient reported marked weight loss, prolonged alopecia, recurrent infections and watery diarrhoea. Examination revealed Salmonella infection, candidiasis and immunological signs of previous toxoplasmosis. Between 1978 and 1981, the patient had had close sexual relations to a patient with haemophilia A. Due to this fact, AIDS was suspected. Serological tests for HIV were not available at the time. The findings in DNA image cytometry (nuclear DNA inclusion bodies, polyploid lymphocyte nuclei and binuclear lymphocytes) suggested a viral infection of the lymphoid cells. Electron microscopy revealed in hepatocytes and cerebral cells intranuclear inclusion bodies whose size and contents were not compatible with an infection caused by cytomegalovirus, herpes virus or Epstein-Barr virus. In autopsy, infections of various organ systems such as pneumonia, tracheobronchitis, urocystitis, pyelonephritis, Candida oesophagitis and enteritis were found.

Pharmacokinetic, bacteriological and clinical studies on SY5555 were performed in children. The results were as follows: 1. A total of 15 patients considered to have bacterial infections were treated with SY5555. Each dose, 5 mg/kg, was orally administered 3 times daily, for 4-11 days. Clinical efficacies of SY5555 in 13 patients with bacterial infections (1 with pneumonia, 2 with bronchitis, each 1 with maxillary sinusitis, 2 with otitis media, 5 with pharyngitis, 1 each with gastroenteritis and pyelonephritis) were evaluated as excellent in 10 patients and as good in 3 patients with an efficacy rate of 100%. Two patients with viral infection and malignant lymphoma were not evaluated. Thirteen causative strains in 7 species were found in 10 patients. Streptococcus pneumoniae in 1/3, Haemophilus influenzae in 2/2, Streptococcus pyogenes 4/4, Salmonella spp. in 1/1, Escherichia coli in 1/1 were eradicated. Only one patient developed mild diarrhea as an adverse reaction. Another patient showed elevated GPT (glutamate pyruvate transaminase). The abnormality was mild and the patient recovered after the cessation of SY5555 administration without specific treatment. 2. MICs of SY5555 were examined against 33 clinical isolates. SY5555 has low MICs against Enterococcus faecalis and other Gram-positive cocci. 3. Pharmacokinetic studies Peak plasma concentrations of SY5555 was 1.15 micrograms/ml at a dose level of 4.9 mg/kg orally administered at fasting. Based on the above results and the broad spectrum of the anti-bacterial activities, SY5555 appears to be a promising antibiotics that is usable as a single agent for the primary therapy of respiratory tract infections, skin soft tissue infections and urinary tract infections in children.

A 27-year-old woman presented to a hospital with symptoms resembling pyelonephritis; respiratory distress did not develop until nearly a day after admission and she subsequently died. The Unexplained Deaths and Critical Illnesses Project of the Centers for Disease Control and Prevention confirmed Sin Nombre virus infection by the results of serological testing and sequencing of the viral genome; staining of Sin Nombre virus antigen in the pulmonary capillaries was relatively weak.

We previously showed that children are more likely to develop viral infections post-kidney transplant while adults are more likely to develop bacterial infections. In this study we determined the overall risk factors for hospitalization with either a bacterial (HBI) or a viral infection (HVI). We analyzed data from 28 924 United States Renal Data System (USRDS) Medicare primary renal transplant recipients from January 1996 to July 2000, for adjusted hazard ratio (AHR) for HBI or HVI in the first 3 years posttransplant. For HVI, significantly higher AHR was seen with (a) recipient age <18 years (AHR 1.57, 95% CI = 1.02, 2.42), (b) donor CMV positive (AHR 1.72, 95% CI = 1.34, 2.19). For HBI, significantly higher AHR was seen with (i) delayed graft function (AHR 1.28, 95% CI = 1.076, 1.518), (ii) primary renal diagnosis chronic pyelonephritis (AHR 1.71, 95% CI = 1.18, 2.49); (iii) associated pretransplant diabetes (AHR 1.80, 95% CI = 1.53, 2.12); (iv) female gender AHR 1.63, 95% CI = 1.41, 1.88). Lower AHR for HVI was seen in CMV-positive recipients and for HBI with more recent year of transplant. Other covariates did not impact significantly in either HVI or HBI.

Ten per cent of girls and 3% of boys will have had a UTI by 16 years of age. The majority are acute, isolated illnesses that resolve quickly, with no long-term implications for the patient. However, UTIs may be associated with underlying congenital abnormalities, and recurrent infections can lead to renal scarring. UTI is defined as bacteriuria in the presence of symptoms. Asymptomatic bacteriuria does not require treatment or investigation. The presentation of UTI is extremely variable. The only way to differentiate a UTI from a viral infection is by testing the urine and this should be carried out within 24 hours in children with non-specific fever. UTIs can also present with vomiting, failure to thrive or persistent irritability. A urine infection in the presence of any of the above symptoms is a pyelonephritis (upper UTI). Children may also present with classical symptoms of cystitis (lower UTI) such as urinary frequency, dysuria and abdominal pain. Most children with UTI, even if febrile, can be managed in the community. If the initial assessment shows a high risk of serious illness, there should be an urgent referral to a paediatrician. The same applies to infants under three months with suspected UTI. It is better to obtain a urine sample by the clean catch method, rather than using urine pads or bags. Leucocyte esterase and nitrite dipsticks are not reliable in children under three, so a negative dipstick does not rule out UTI. Not every child needs to be referred after a first UTI. However, they should all be evaluated to help determine which require renal imaging as well as identifying triggers for recurrence. GPs are central to the identification of children at risk of renal pathology. All children who are diagnosed and treated for a UTI must be assessed for risk of renal abnormalities and/or recurrence.

The incidence, risk factors and outcome of graft pyelonephritis are variably described in literature. All patients who had been transplanted at our center between January 2002 and November 2006 and had presented with acute graft dysfunction were subjected to biopsy. Those patients who had neutrophilic casts and interstitial inflammation with predominant neutrophils were included in the study. Out of the 265 patients, 110 were transplanted in the period and underwent biopsy for graft dysfunction. Out of the 110 patients, 26 had biopsy proven acute graft pyelonephritis (AGPN). Nine patients had early AGPN (within 6 months) and the other 17 had late AGPN. Nearly 19% of patients were culture negative and five patients had no clinical features of urinary tract infection; AGPN being a surprise finding on biopsy. Among the risk factors, only hepatitis C virus infection was significantly associated with AGPN. All patients received 4-6 weeks of antibiotics with at least 3 weeks of parenteral antibiotics. Majority (75%) of our patients experienced relapse of AGPN. Graft function was significantly lower 6 months after onset when compared to baseline, portending a poor outcome for these patients. Out of 26, 7 (27%) of our patients had biopsy features of concomitant acute cellular rejection. The treatment of acute rejection, however, did not improve the outcome.

Fever in children is a very common symptom associated most of the time with a viral infection. However, in 7% of children, fever without source is the first symptom of a serious bacterial infection such as pneumonia, meningitis, pyelonephritis or bacteremia. The key point in clinical examination of these children is the early identification of toxic signs. Because SBI prevalence is higher in very young children (1-3 month-aged), they required a specific management with some systematic complementary investigations and a broad indication of probabilistic antibiotherapy treatment.

- Fever in children is usually caused by benign viral infection.- Approximately 1-10% of children with fever has or develops a serious infection such as pneumonia, meningitis or pyelonephritis.- It is more important to timely recognize symptoms that may indicate a potentially serious disease course than to make an exact diagnosis.- Children < 3 months are at greater risk for a serious disease course.- During follow-up it is important to provide parents with proper advice on the expected disease course and who they should contact, and when, in cases of deterioration or concern.- Paracetamol or ibuprofen should only be given when there is a combination of fever and pain. Combating fever is not an end in itself.

Pediatric fever is one of the most common presenting complaints to emergency departments (ED). While often due to a viral illness, in young children without a source the most common bacterial infection is pyelonephritis. For this reason, when no focal source can be identified a urinary specimen is recommended. In young children who are unable to urinate on demand, a straight catheter is required to obtain a sterile specimen. This is generally a benign procedure and is performed frequently in EDs. We report a case of a young girl who underwent straight bladder catheterization and was subsequently found to have a retained catheter that had become knotted in the bladder. This case report highlights a rare complication of this common procedure and describes the technique required to remove the catheter. An understanding of these issues may avoid the need for transfer to a pediatric facility or for subspecialty consultation.
