RESUMEN
BACKGROUND: Urinary tract infections (UTI) are one of the most common bacterial infections in children and a major cause of hospitalization. In this study we investigated the clinical characteristics, causative uropathogens; their antibiotic susceptibility and resistance patterns, treatment modalities and efficacy in children hospitalized for UTI in a tertiary care setting. METHODS: Patients hospitalized for an upper UTI between March 2009 and July 2014 were enrolled. The urine culture-antibiogram results and accompanying urinary tract abnormalities were recorded retrospectively. RESULTS: A total of 142 patients (104 girls, 73.2%; 38 boys, 26.8%) were enrolled. Mean patient age was 32.6 ± 4.1 months. History of recurrent UTI was present in 45.8% (n = 65), with prior hospitalization in 12.0% (n = 17). Frequency of vesicoureteral reflux was 18.3% (n = 26). Gram-negative enteric microorganisms yielded growth in all culture-positive UTI and the most common microorganism was Escherichia coli (n = 114, 80.3%). Extended spectrum beta-lactamase-producing (ESBL (+)) bacterial strains were detected in 49.3% (n = 70), with third-generation cephalosporin resistance in all and increased duration of hospitalization. CONCLUSIONS: The prevalence of UTI with ESBL (+) bacterial strains with multi-drug resistance is increasing in the hospitalized pediatric population, therefore rational use of antibiotics is essential.

BACKGROUND: Crescentic glomerulonephritis (CsGN) is characterized by crescents in 50% or more of glomeruli and clinically by a sudden and progressive decline in renal function. METHODS: We evaluated the etiology, clinical features, prognostic factors and long-term outcome of CsGN. Between January 2000 and December 2010, 45 children (26 girls, 19 boys) with biopsy-proven CsGN (>50% crescents) were investigated retrospectively. RESULTS: The mean age of the patients was 130.86±33.77 months. The mean duration of symptoms prior to diagnosis was 26±12 days (4-40 days). Most of the children had hypertension (62.2%), macroscopic hematuria (73.3%), oligoanuria (44.4%), edema (51.1%) and purpuric rash (40%) at presentation. The final clinical status of the patients was complete remission (n=21), partial remission (n=5) or chronic kidney disease (n=19). Adverse outcomes were significantly associated with a long duration between the onset of symptoms and treatment (P=0.038), the presence of oligoanuria (P=0.006), a severe decreased glomerular filtration rate (GFR <30 mL/min/1.73m²) and the need for dialysis (P=0.003) on admission, the ratio of crescents (>75%) (P=0.03), and the ratio of fibrous crescents (P=0.015). CONCLUSION: The outcome of CsGN in children continues to be poor, and it should be treated as a renal emergency.

Behçet's disease (BD) is a multisystemic inflammatory disorder of unknown etiology. Neurologic involvement is known to be the most devastating feature of BD. The frequency and types of neurologic involvement in the pediatric age group are not clear, and the available information is limited to case reports. Here, we report a BD patient who presented with urinary incontinence as the initial feature of spinal cord involvement.

BACKGROUND: Identifying the risk factors is important in prevention of urinary tract infections (UTIs) in children. The aim of this study is to evaluate the association of UTI and idiopathic hypercalciuria (IHC). METHODS: Two hundred and twenty-four children aged between 1 month and 16 years and diagnosed to have UTI were evaluated for urinary calcium excretion. The children were diagnosed to have IHC if their urinary calcium/creatinine ratios in at least two different spot urine samples were >0.6 between 0-1 year old and ≥0.21 over 1 year or daily calcium excretion >4 mg/kg. RESULTS: The frequency of IHC was found to be 16.7%. Family history of urolithiasis, parental consanguinity, presentation with abdominal pain, loss of appetite, and discomfort were found to be significantly higher in the IHC group. No association was found between IHC and the recurrence of UTI, presence of vesicoureteral reflux, renal scar formation, and the prognosis. CONCLUSIONS: IHC should be considered among the risk factors for UTI and should be investigated particularly in patients with family history of urinary stones and suggestive complaints of IHC.

BACKGROUND: Peritoneal dialysis (PD) is an effective and successful therapy for end-stage renal disease (ESRD). However, PD does not have a life-long effectiveness, and peritoneal membrane failure is commonly observed in long-term PD patients. We hypothesized that ultrasonography could be used to follow these patients. METHODS: We recruited two patient groups (age range 3-18 years), of whom 20 had ESRD with ongoing PD for ≥24 months (study group) and 20 were pre-dialysis non-ESRD patients (control group). None of the patients had peritonitis during the preceding 3 months, and none had a history of abdominal surgery or malignancy. We measured the sonographic thickness of the parietal peritoneum and obtained Doppler indices of the superior mesenteric artery (SMA) by trans-abdominal ultrasonography. RESULTS: Peritoneal thickness as determined by sonography was significantly greater in the PD group than in the controls. The correlation between duration of PD and thickness of the peritoneal membrane was linear and statistically significant. We categorized all 20 patients as either rapid transporters or slow transporters for both creatinine and glucose. The peritoneal membranes of patients who were rapid transporters for both creatinine and glucose were significantly thicker than those of the slow transporters. No statistical difference was found between the Doppler indices of the SMA between the groups. CONCLUSION: Thickness of the parietal peritoneum as determined by sonography is associated with PD duration and transport characteristics. We conclude that ultrasonography is a non-invasive and practical method which can be useful for following PD patients.

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that may affect any organ of the body. We report here an unusual case of seronegative SLE presented as vasculitis with rash, lower gastrointestinal system bleeding and acute renal failure. The patient was a 13-year-old boy, with abdominal distention, pretibial edema, arthritis and petechia on bilateral ankles. He had deteriorated renal functions (creatinine 1.65 mg/dl), hypoalbuminemia (1.6 g/dl) and hypocomplementemia with nephrotic range proteinuria and hematuria. He developed pleural effusion and peritonitis. Serum ANA, anti dsDNA, p ANCA, c ANCA, anticardiolipin IgM and IgG titers were negative. A renal biopsy was performed which revealed diffuse proliferative glomerulonephritis with full-house staining pattern in immunofluorescent microscopic examination suggesting Class IV Lupus Nephritis. He was administered a total of six courses of monthly intravenous pulse methyl prednisolone, dipyridamole, oral cyclophosphamide followed by azothiopirine and oral prednisolone therapy. The renal functions and serum albumin levels turned normal but peritonitis persisted and disappeared after the third pulse steroid therapy. In conclusion, we presented this patient to remind the possibility of SLE in such seronegative patients with unusual findings in order to avoid the delay in the management of this disease with high mortality and morbidity if not treated. Full-house nephropathy is an important clue especially for the diagnosis of ANA negative SLE.

Neurofibromatosis type 1 (NF1) is a relatively common autosomal dominant disorder affecting mainly ectodermal and mesodermal tissues. It is well known that patients with NF1 have an increased risk of developing benign and malignant tumors, but its association with autoimmune diseases has been rarely reported. Systemic lupus erythematosus is an autoimmune chronic inflammatory disease that has the potential to affect various organ systems. There are four cases with NF1 and SLE reported in the literature up to date. Here, we report a 9-year-old girl presenting with NF1 and SLE, and to our knowledge, this is the first childhood case in the literature.

AIM: To investigate the frequency of MEFV mutations and their associations with the clinical and laboratory findings in children with Henoch-Schönlein purpura (HSP). METHODS: One hundred and seven children with HSP were investigated for 12 common MEFV mutations. RESULTS: Forty-seven patients (43.9%) were found to have one of the MEFV mutations. Eight patients (7.5%) were homozygous for one mutation, 33 (30.8%) were heterozygous for one and six (5.6%) were compound heterozygous for two mutations. There were no age and sex differences between patients with or without mutations. Scrotal involvement was statistically more frequent in patients with mutations. Leucocyte counts, erythrocyte sedimentation rates, serum C-reactive protein (CRP) concentrations, number of patients with increased CRP levels and number of patients with increased immunoglobulin A concentrations were found to be higher in patients with MEFV mutations. p.M694V was the most frequent mutation and was found to have effects on clinical and laboratory findings in children with HSP. Fifteen patients were started on colchicine with the diagnosis of familial Mediterranean fever (FMF). CONCLUSION: MEFV mutations are more frequent in HSP than in the general population, and mutation carriers may have more severe clinical findings with higher inflammatory response, suggesting a dysregulation of the inflammatory response because of defective gene encoding the protein pyrine. Investigation of these mutations may be beneficial to follow-up the susceptible patients more closely leading to early diagnosis and treatment of FMF.

BACKGROUND: The Pediatric Advanced Life Support Program (PALS) course very important for teaching about intubation, resuscitation, shock, trauma, respiratory failure and rhythm disturbances. The aim of the present study was to evaluate the effect of the PALS course on pediatric residents' intubation success during their rotation, daytime and night-time practice in the pediatric intensive care unit (PICU). METHODS: The study was carried out from 1 March 2005 to 28 February 2007. The study period had two parts, in that the number of attempts and successful intubations performed by pediatric residents, and the pediatric intensivist successful intubation ratio were evaluated in two different periods: before the PALS course, 1 March 2005-28 February 2006, and after the PALS course, 5 March 2006-28 February 2007. The participating residents' pediatric levels (PL) were classed as PL-1, PL-2, PL-3, PL-4, and all had first experience in the PICU at the PL-1 level. The PALS instructor was a pediatric emergency or intensive care doctor. We evaluated whether the PALS course influenced intubation success or not. RESULTS: Sixteen residents participated in the study. The proportion of successful intubations was 110 (53.3%) and 104 (65.4%) attempts before and after the PALS course, respectively. The proportion of intubations done by intensivists decreased from 49.1% to 31.7% before and after PALS. The most frequently used endotracheal tube (ETT) internal diameter (ID) was 4.0 mm, and cuffed ETT was used 16% and 21% before and after the course, respectively. Appropriate placing of ETT tip occurred 70.4% and 82.2% of the time before and after the PALS course, respectively. Proportion of successful intubations by residents increased in all levels, except for PL-1. The most important reason for unsuccessful attempts was inappropriate patient position. Only one patient could not be intubated, and laryngeal mask airway was used in that case. During intubation, complications were broken teeth in two patients before the course, and subglottic stenosis developed in only one patient due to cuffed ETT. CONCLUSION: Successful intubation is a life-saving intervention during resuscitation, ETT revision for extubation or obstruction for extubation or obstruction during mechanical ventilation. This skill can be developed in the PALS course and by clinical study in PICU and pediatric emergency services. The PALS course must be given to pediatric residents especially within the first year. Also, cuffed ETT can be used for infants and children.

We present here two girls with cystinosis initially diagnosed as Bartter syndrome. Both cases were admitted with hypokalemic, hypochloremic alkalosis. Their proximal tubular functions, ophthalmologic and bone marrow examinations were normal. They were started on therapies with the diagnosis of Bartter syndrome. The first patient developed signs of rickets, and the second patient was lost to follow-up and readmitted with chronic renal failure. On reevaluation cystine crystals were detected in cornea and bone marrow aspirates of both patients. We aimed to remind the rare presentation of cystinosis with metabolic alkalosis mimicking Bartter syndrome by these two cases and review the literature.

The diagnosis of polyarteritis nodosa (PAN) is often delayed because patients present with diverse clinical symptoms, but with less disease-specific signs. However, early diagnosis and treatment of PAN is necessary to prevent serious organ damage. Herein, we present a boy in whom the diagnosis of classical PAN was established rapidly with ultrasound and computed tomography (CT) angiography. Moreover, complete disappearance of the aneurysms after one month of therapy was documented. This case is presented in order to underline the role of new imaging techniques in the diagnosis and follow-up of patients with PAN.
