ABSTRACT
Acute idiopathic scrotal edema (AISE) is a self-limiting condition that is characterized by acute scrotal swelling and erythema. AISE is a very rare cause of acute scrotum, especially in neonates. We report a case of AISE in a 26-day-old infant who was admitted to the outpatient clinic with swelling and erythema of the penis and scrotum for a week. His vital signs were stable, and laboratory findings were non-specific. A diagnosis of AISE was made using scrotal ultrasonography with color Doppler. His symptoms resolved within four days after the onset of supportive treatment, and he was discharged from the hospital. In neonates with an acute scrotum, AISE should be considered to prevent unnecessary surgical exploration.

Acute hemorrhagic leukoencephalitis (AHLE) is an acute, rapidly progressing, fulminant demyelinating disease. It is a rare disease of the central nervous system with high mortality; survivors commonly present with significant neurological deficit. We report the case of a 16-month-old girl who survived AHLE and presented with the associated neurologic deficit. The patient came into the emergency department with febrile seizure. She showed bilateral pinpoint-sized pupils and hyperactive deep tendon reflexes. Her mental status was initially drowsy and rapidly progressed to stupor. Extensive demyelination and microbleeds were found in the cerebral white matter, thalamus and left cerebellum on Magnetic resonance imaging (MRI) scans. Her mental status was improved by intravenous administration of immunoglobulin and methylprednisolone. Five months after being discharged, increased white matter connectivity was found on color-coded follow-up MR diffusion tensor imaging (DTI) as compared to previous MRI. We therefore suggest adding the DTI technique when a follow-up MRI is performed in patients with AHLE. It could be useful to visualize the status of axonal injury and to encourage patients and their parents to continue the rehabilitation program.

PURPOSE: Disruption of normal renal development can lead to congenital anomalies of the kidney and urinary tract, including renal hypodysplasia. We aimed to clarify whether small kidney size affects clinical manifestations in children with urinary tract infection (UTI). METHODS: One hundred fifty-four patients who had their first symptomatic UTI between January 2014 and June 2015 were enrolled in this study. Differences in kidney size were estimated based on percent uptake of (99m)Tc-dimercaptosuccinic acid (DMSA) in scintigraphy. The patients who showed more than 10% difference in kidney size on DMSA scintigraphy with none or minimal cortical defects were included in group A. (group A, n=17). Laboratory, clinical, and imaging results were compared with those of the other patients (group B, n=137). RESULTS: Group A had a relatively higher incidence of vesicoureteral reflux than group B (44% vs 20%, P<0.05). The levels of plasma neutrophil gelatinase-associated lipocalin (NGAL) and serum C-reactive protein were significantly higher in group A (193 [64-337] vs 91 [59-211] ng/mL and 4.1 [0.5-11.9] vs 2.1 [0.7-5.3] ng/mL, respectively; all P<0.05). Linear regression analysis revealed that plasma NGAL level strongly correlated with the difference in renal uptake in DMSA scintigraphy in group A (R²=0.505). CONCLUSION: The difference in kidney size could influence the clinical course and severity of pediatric UTI.
