Since it was first detected, novel coronavirus disease rapidly spread, striking over 4 million people worldwide. 1 While adults with COVID-19 demonstrate a range of disease severity with 20% of infected adults being critically ill and an estimated fatality rate as high as 2%, children mostly suffer from a mild disease, only minority presenting with respiratory distress syndrome or multi-organ failure. [2][3][4] However, the role of infected children in spreading the virus to their older relatives and caregivers is yet to be determined.Many countries struggle to stave off the spreading of COVID-19 by using different strategies. In many countries, including Israel, authorities instructed the public to stay at home and to avoid visiting local clinics and hospitals as much as possible while using more telemedicine-based practice. 5 However, emergent medical situations continue to appear alongside the current outbreak and their diagnosis should still be made promptly. Delayed diagnosis and treatment of those common paediatric conditions may lead to significant morbidity that may overweigh the harm caused by COVID-19 infection.Appendicitis is the most common abdominal surgical emergency in paediatric population. 6 Early diagnosis of appendicitis

This large longitudinal study provides new data on the decrease in eGFR with age. Accurate prediction of the natural rate of GFR decline might be used to distinguish between normally aging kidneys and those with chronic disease. This approach could avoid unnecessary diagnostic procedures in the former and facilitate appropriate treatment in the latter.

Our findings support the applicability of VCD measurement in the estimation of hydration status in paediatric haemodialysis patients. The combination of clinical parameters and measurement of IVCD may enable more accurate evaluation of hydration of children on haemodialysis.

Seven patients aged 13 to 17.5 years developed acute renal failure after treatment with a variety of non-steroidal anti-inflammatory drugs (NSAID): naproxen, diclofenac, ibuprofen, dipyrone and paracetamol. Six of the patients used more than one kind of NSAID. None of the patients had previous history of renal disease or concomitant treatment with other drugs. The time interval between NSAID administration to the emergence of symptoms ranged from 1 to 4 days. The most common presenting symptoms were flank pain (4 patients), abdominal pain (3 patients) and vomiting (3 patients). All patients had normal urine output. Microscopic hematuria and proteinuria were found in 5 patients and leukocyturia in 2. Serum creatinine ranged from 1.3 to 8.3 mg% at presentation. Kidney biopsy was performed in 3 patients and showed findings consistent with mild interstitial inflammation in 1 patient, and normal renal tissue in 2. All patients were treated with intravenous fluids, 1 received corticosteroids. Renal function completely normalized in all patients within 7 to 16 days.

Deferasirox is a recently approved oral iron chelator for treatment of patients with transfusion-related iron overload. Although renal function disturbances were recognized, proximal renal tubulopathy was not addressed in published safety reports for deferasirox. Although subclinical proximal tubulopathy was described in β-thalassemia homozygotes, overt Fanconi kidney is not an established disease complication. We describe 4 cases out of 50 children and adults with transfusion-dependent β-thalassemia, treated with deferasirox for iron overload, who developed clinically significant Fanconi syndrome. Three had concomitant infectious events; the fourth case was entirely spontaneous. In addition, all 4 patients were moderately to well chelated. Cessation of deferasirox resulted in prompt recovery. We propose the necessity for diligent monitoring for proximal tubule nephropathy, possibly related to infectious events, during treatment with deferasirox.

Vesicoureteral reflux (VUR) after a first episode of urinary tract infection (UTI) is apparently diagnosed much more frequently (25%-40%) in children than in neonates. The aims of the study were to determine the actual rate of VUR in neonates with UTI and to define the clinical clues to its diagnosis. The study sample included term infants with a diagnosis of UTI during their first month of life who were seen in this hospital between January 1997 and May 1999. All infants underwent complete diagnostic work-up (renal ultrasound and voiding cystourethrography [VCUG]). The medical files were reviewed for patient sex, age at UTI diagnosis, laboratory findings (including causative pathogen), and ultrasonographic findings. These parameters were correlated with the finding of VUR on VCUG. Sixty-four neonates (55 males, 9 females) with UTI were included in this study. UTI was 6 times more common in males than females, although the incidence of VUR was equal between the sexes (about 20%). The presence of VUR was associated with a significantly younger age at presentation of UTI (11.4+/-4 vs 16.9+/-6.6 days, p<0.01). VUR was diagnosed at a fourfold higher rate in neonates with Klebsiella-induced UTI compared to those with E. Coli-UTI. In 80% of those with significantly abnormal ultrasonographic findings VUR was found on VCUG. Jaundice was noted at UTI diagnosis 3 times more often in infants with VUR, and elevated creatinine level, 2.5 times more often.
