ABSTRACT
BACKGROUND: We aimed to evaluate the predictability of extended-spectrum beta-lactamase (ESBL)-producing bacteria (PB) with inflammation markers and hemogram parameters as neutrophil-lymphocyte-ratio (NLR), platelets-lymphocyte-ratio (PLR) and mean-platelet-volume (MPV) in infants with febrile urinary tract infection until the urine cultures are resulted. METHODS: Infants between 2-24 months hospitalized for the first febrile urinary tract infections were grouped as those infected with ESBL-PB and non-ESBL-PB. The demographic and laboratory data (inflammation markers and hemogram parameters) and the ultrasonographical findings were compared between the two groups. RESULTS: A total of 232 patients were included in the study. The mean age was 8.82 ± 5.68 (2-23) months and 114 (49%) of them were female. Escherichia coli was the most common isolated bacteria (79%) followed by Klebsiella pneumoniae (15.5%) in urine cultures. There were 88 patients in ESBL-PB infected group and 144 patients in the non-ESBL-PB group. The hematologic parameters such as white blood cell count (WBC) count, NLR, PLR, MPV and procalcitonin (PCT) were similar between the two groups. Only the rate of ultrasonographic abnormalities was significantly higher in infants infected with ESBL-PB (p=0.012). The risk of ESBL-PB positivity in urine cultures increased with age (OR 1.068, 95% CI 1.002-1.139, p=0.045), PCT (OR 1.094, 95% CI 1.011-1.184, p=0.025), and ultrasonographic abnormalities (OR 3.981, 95% CI 1.792-8.845, p=0.001). CONCLUSIONS: Platelet counts, WBC, MPV, NLR, PLR, and PCT were not reliable markers, however having an ultrasonographic abnormality is the most important independent risk factor for prediction of infection with ESBL-PB.

BACKGROUND: Chronic kidney disease (CKD) may lead to increase in serum levels of peptide hormones as a result of changes in peripheral metabolism. The pathogenesis of uremic hyperprolactinemia in CKD is not fully understood. Plasma prolactin levels are elevated in women, pubertal girls, and also in men with chronic kidney disease. But this is not comon in prepubertal boys. Also in prepubertal children and postmenopausal women, hyperprolactinemia rarely results in galactorrhea. We aimed to discuss hyperprolactinemia and galactorrhea in a 12-year-old male with CKD. CASE: A twelve-year-old boy with chronic kidney disease (CKD) suffered from bilateral galactorrhea. He was on follow-up at Pediatric Nephrology Department from the age of two due to bilateral dysplastic kidney. On physical examination, his weight was - 0.59 SDS, height was -2.82 SDS, Blood pressure was 115 / 72 (75p), stretched penis length was 6 cm, testicular volume was 3mL / 3mL, pubic hair was Tanner Stage 1, breast examination did not reveal plaque on bilateral breast. He was receiving recombinant erythropoietin, sodium bicarbonate, polystyrene sulfonate, calcium acetate, and calcitriol treatments. Glomerular filtration rate was 23ml/min/1.73 m2 (CKD stage IV). Serum prolactin (PRL) was > 200 µg/L (N, 2.64-13.13). The pituitary adenoma was excluded with pituitary and cranial magnetic resonance imaging (gadolinium). Cabergoline (0.5 mg/ twice weekly) was initiated to decrease PRL levels and reduce galactorrhea. In the second week of treatment, serum PRL level was suppressed (0.4 µg/L) and galactorrhea was completely resolved. CONCLUSIONS: Although uremic hyperprolactinemia is very rarely seen in childhood, it is important to evaluate, and initiate an appropriate treatment since it is associated with delayed puberty and infertility in adulthood in many cases.

OBJECTIVE: We aimed to evaluate the effects of blood pressure (BP) values obtained by 24-h ambulatory BP monitoring (ABPM) of hypertensive children and adolescents on left ventricular mass index (LVMI). METHODS: Patients diagnosed with HT with BP measurements confirmed with ABPM and evaluated with echocardiography for LVMI were included. The patients were divided into two groups according to their BMI as obese and nonobese. SDSs of ABPM parameters were compared between the groups. RESULTS: A total of 158 children with HT were included in the study. Ninety of these patients were obese. In obese and nonobese cases, mean SDS levels were similar in ABPM parameters, whereas LVMI was significantly higher in obese patients ( P = 0.049). There was a significant correlation between LVMI and 24-h SBP SDS, daytime SBP SDS, 24-h SBP load and daytime BP load. In obese cases, there was a statistically significant correlation between LVMI and 24-h SBP SDS, daytime SBP SDS, 24-h SBP load, daytime SBP load as well as nighttime SBP SDS and nighttime SBP load. When the whole group was evaluated, 24-h SBP SDS was the most effective parameter influencing LVMI ( P = 0.001). Similarly, the most effective ABPM parameter on LVMI in obese patients was 24-h SBP SDS ( P = 0.001). CONCLUSION: A significantly higher rate of LVMI in obese patients suggests that obesity itself is an effective factor on LVMI. In addition, systolic hypertension is more effective on cardiac functions compared with DBP measurements and systolic-DBP dipping ratios.

INTRODUCTION: Multisystem inflammatory syndrome in children (MIS-C) is a rarely seen severe complication of coronavirus disease-2019 (COVID-19). Although fever is one of the indispensable symptoms, other infections should be considered in the differential diagnosis during the pandemic. CASE REPORT: An 8-year-old and a 16-year-old female patient were admitted with fever, vomiting, headache. Both had fulfilled the criteria and were diagnosed with MIS-C. However, they both had remarkable persistent costovertebral angle tenderness, which was unexpected in MIS-C. In Case-1, urine analysis showed microscopic hematuria without pyuria, and urine culture showed no bacterial growth. Case-2 had microscopic hematuria and pyuria with Escherichia coli growth in urine culture. Contrast-enhanced computed tomography showed wedge-shaped hypodense multiple lesions in bilateral kidneys for Case-1, in the right kidney for Case-2. They diagnosed acute focal bacterial nephritis (AFBN). CONCLUSIONS: The diagnostic criteria of MIS-C can overlap with the symptoms of other severe septic infections such as AFBN, which is a rare urinary tract infection, diagnosed by imaging of localized renal inflammatory mass-like or wedge-shaped lesion. A detailed anamnesis and careful physical examination may help differential diagnosis.
ABSTRACT
BACKGROUND: Herein we present our experience with abatacept in a patient diagnosed with primary focal segmental glomerulosclerosis (FSGS) and resistant to steroid and other immunosuppressives. CASE: A 17-year-old girl was diagnosed with idiopathic nephrotic syndrome (NS) at the age of 8 years. Kidney biopsy was performed when she did not respond to 6-weeks of steroid (2mg/kg) therapy followed by three doses of pulse methylprednisolone (PMP) and considered as steroid resistant NS. The biopsy revealed focal segmental glomerulosclerosis (FSGS) and cyclophosphamide was added to the steroid treatment but the patient had no response. The genetic analysis revealed G34G/A318A compound homozygous synonym aminoacid variation in NPHS2 gene, thus all immunosuppressive regimes were stopped and she was put on supportive treatment. Throughout this period, she had nephrotic range of proteinuria, however serum albumin levels were > 3g/dl. At the end of two years, the patient had NS with severe edema and hypoalbuminemia. When the genetic analysis was interpreted again, it was found to be consistent with a polymorphism rather than a mutation. Following 3 doses of PMP, oral steroid treatment was resumed and cyclosporine (CsA) was added to the treatment at the fifth year of follow up. However, she was unresponsive to CsA at the end of the first year as well as mycophenolate mofetil used for 12 months and rituximab used for 6 months, respectively. Then abatacept was instituted and proteinuria decreased below 1 gr/day and serum albumin levels increased to 3 g/dl at the end of 6 doses. Serum albumin levels remained stable in the following 7 months. CONCLUSION: Partial remission including the decrease in proteinuria and increase in albumin levels achieved in our patient encourages the usage of abatacept in patients who do not respond to multiple immunosuppressive therapies.

OBJECTIVE: Calyceal diverticulum (CD) is rarely diagnosed in children. It mimics other cystic lesions of the kidney and may be very difficult to identify. Displaying the communication of these fluid-filled cavities with the collecting system of the kidney via imaging methods is the key diagnostic method. The purpose of this study is to determine the presence of calyceal diverticulum in pediatric patients followed up due to simple renal cyst and/or parapelvic cyst. MATERIAL, AND METHOD: Patients who were newly diagnosed or being followed up with the ultrasonographic diagnosis of simple cyst(s) or parapelvic cyst(s) in the Department of Pediatric Nephrology of Izmir University of Health Sciences Tepecik Training and Research Hospital between December 2015 and July 2018 were included in the study. Age, gender, admission symptoms, recurrent urinary tract infections, stone disease, trauma history, accompanying urinary system and systemic anomalies, localization, and size of the cyst(s) at admission and during follow-up, treatment type and developing complications were noted. Contrast MR urography was applied to all patients. RESULTS: A total of 43 patients [mean age:132 ± 54.9 (12-228) months] including 25 girls were enrolled in the study. The mean follow-up period was 36. 74 ± 19 (1-90) months. The cysts were located mostly in the right kidney and also in the upper pole of the kidney. The mean cyst size was 20.4 ± 11 (8-58) mm at admission, and comparably 20.3 ± 8.6 (10-45) mm at the end of the follow-up. In contrast MR urography, a total of 16 cases were observed at first glance to be associated with pelvicalyceal system. However, in the postcontrast images taken at the 5th minute it was determined that 9 of them were compatible with calyceal diverticulum. CONCLUSION: Although it is thought that well-circumscribed solitary renal fluid collections may be thought to be a simple renal cyst at first glance, the differential diagnosis of calyceal diverticulum (CD) should be absolutely kept in mind. Contrast studies and late-phase postcontrast images are needed for the diagnosis of CD. Although the standard management of CDs in children is conservative, surgical intervention may be rarely required.

INTRODUCTION: Urolithiasis (UL) in infancy has different incidence, etiology, presentation and course compared to UL in childhood and in adults. We evaluated the clinical, radiological, metabolic factors and course of infant UL in western Turkey. METHODS: Medical records of the infants between 1 and 12 months of age with a diagnosis of UL were reviewed retrospectively for gender, gestational age, age at diagnosis, presenting symptoms, past medical history, parental consanguinity, family history of UL, urinary tract abnormalities, urinary tract infections, localization-size-number of stones, course of stones, treatment modality of UL (medical vs surgical) and follow up duration. Patients were grouped as those who did not require surgical intervention (Group 1) and those who underwent any kind of stone surgery (Group 2). Both groups were compared for the study parameters. RESULTS: There were 80 infants (48 males) with a mean age of 6.0 ± 2.9 months at diagnosis. Mean follow-up duration was 29.7 ± 23.1 months. Two thirds of the patients presented with symptoms/signs not directly related to urinary system. Predisposing factors included metabolic abnormalities in 24 (30%) patients and urinary tract malformations in 9 (11%) patients. Group 1 (n = 58) and Group 2 (n = 22) were not different with respect to the study parameters except for the larger stone size and higher rate of hyperuricosuria in Group 2. Stone size of 4.5 mm has a 72.7% sensitivity and 74.1% specificity for predicting surgical intervention. Infants treated medically and those followed by hydration only did not differ for regression rate of stones and for requirement for surgical intervention. However, metabolic abnormalities were significantly higher in medically treated infants. CONCLUSION: Every infant with urolithiasis should be evaluated for risk factors. Modification of such predisposing factors when possible may mitigate the notably high recurrence rate of UL in children. Increased awareness of infant UL may allow for earlier detection, improved evaluation and follow up, and may thereby decrease the morbidity of the disease.

BACKGROUND: Myalgia is one of the presenting symptoms of Familial Mediterranean Fever (FMF), which is reported at a rate of 27-39.6%. Recurrent fasciitis in those cases are extremely rare. We aimed to present a case with FMF having radiologically proven fasciitis. CASE: An 11-year-old male patient with a diagnosis of FMF and M694V homozygote mutation, using colchicine regularly at a dose of 2 mg/day (0.08 mg/kg/day) for 4 years; was admitted to the hospital with severe pain and tenderness on the right calf. There were no accompanying symptoms like fever or abdominal pain. He described three similar episodes with pain and tenderness in left and right calves, which were not accompanied by fever in the last 6 months. The erythrocyte sedimentation rate and C-reactive protein levels were high and serum creatinine kinase was normal. The day after initiation of non-steroidal anti-inflammatory drug (NSAID), his complaints regressed. However, after a week, he again had a severe calf pain. Lower extremity arterial and venous doppler ultrasonography was normal. Increased peripheral signal intensity and fasciitis around the soleus muscle was defined in MRI. With NSAIDs, myalgia disappeared in a few days and acute phase reactants decreased within a week. In the follow up, canakinumab was prescribed due to febrile attacks as frequent as once a month and calf pain observed almost weekly. Thereafter, both febrile attacks and recurrent debilitating calf pain were completely ceased. CONCLUSION: There are three cases in the literature with fasciitis related myalgia. With this case, we wanted to emphasize fasciitis as a cause of FMF associated myalgia on MRI. In such cases MRI may be helpful to demonstrate fascial involvement.
