Retinal hemorrhages and damages from tractional forces associated with infantile abusive head trauma evaluated by wide-field fundus photography.

We evaluated the distribution and types of retinal hemorrhages (RHs) and other damages in eyes with abusive head trauma (AHT). This retrospective, consecutive case series of AHT and non-AHT conditions involved 54 children with AHT, 43 children with head bruises, and 49 children with blunt eye trauma, each of non-AHT supported by reliable witness accounts. RHs and other damage were evaluated using ophthalmoscopy and wide-field fundus photography.

Ultrasonography as a Diagnostic Support Tool for Childhood Takayasu Arteritis Referred to as Fever of Unknown Origin: Case Series and Literature Review.

Introduction: Childhood Takayasu arteritis (c-TA) often shows nonspecific symptoms, such as fever of unknown origin (FUO). Delay of diagnosis may result in organ dysfunction by arterial occlusion; therefore, early diagnosis is very important. Although ultrasonography is the first-line screening tool for children with FUO, its diagnostic efficacy of evaluation of systemic arteries in c-TA that presents as FUO remains unclear.

Incidence of hospitalization for abusive head trauma in Chiba City, Japan.

Backgrounds: This study aimed to examine the incidence of abusive head trauma (AHT) admissions by calculating admission rates of AHT cases among infants <12 months old in a population-based sample in Chiba city, Chiba prefecture, Japan.

Methods: We retrospectively examined medical records of infants admitted to all pediatric secondary and tertiary hospitals in Chiba city between 2011 and 2015. We collected 13 AHT cases, as assessed by hospital-based multidisciplinary child protection teams.

Acute hematogenous pelvic osteomyelitis: appropriate timing for magnetic resonance imaging.

Background: The precise time of appearance of bone marrow edema in acute hematogenous pelvic osteomyelitis (AHPO) is unknown. The purpose of the present research is to clarify the time of appearance of bone marrow edema on magnetic resonance imaging (MRI) in AHPO. Our hypothesis was that onset is slower than in long-bone osteomyelitis.

Indication for voiding cystourethrography during first urinary tract infection.

Background: There is confusion surrounding the precise indications for voiding cystourethrography (VCUG) during the assessment of vesicoureteral reflex (VUR) after a first febrile urinary tract infection (UTI). The aim of this study was to determine the combination of clinical, laboratory and ultrasonography factors correlating with grades IV-V VUR in young children with a first febrile UTI.

Methods: Children 0-24 months of age who were brought to the emergency department at National Center for Child Health and Development with the diagnosis of first time febrile UTI between March 2004 and May 2011, were enrolled.

Efficacy and safety of sirolimus treatment for intractable lymphatic anomalies: A study protocol for an open-label, single-arm, multicenter, prospective study (SILA).

Introduction: Lymphatic anomalies (LAs) refer to a group of diseases involving systemic dysplasia of lymphatic vessels. These lesions are classified as cystic lymphatic malformation (macrocystic, microcystic or mixed), generalized lymphatic anomaly, and Gorham-Stout disease. LAs occur mainly in childhood, and present with various symptoms including chronic airway problems, recurrent infection, and organ disorders.

Osteomyelitis of a sacral neurocentral synchondrosis: a case report of another metaphyseal equivalent.

Pelvic osteomyelitis may occur in a metaphyseal equivalent, defined as a portion of flat or irregular bone that is adjacent to cartilage. The pelvic bone is known to have several metaphyseal equivalents and of these, the sacroiliac joint is the most frequent site of involvement. However, a sacral neurocentral synchondrosis has not been recognized as a metaphyseal equivalent, and there have been no previous reports describing this as the site of origin of sacral osteomyelitis.

Pathological characterization of pachydermia in pachydermoperiostosis.

Pachydermoperiostosis is a rare hereditary disease, which presents with the cutaneous manifestations of pachydermia and cutis verticis gyrata. Histological findings in pachydermia frequently include dermal edema, mucin deposition, elastic fiber degeneration, dermal fibrosis and adnexal hyperplasia. However, the severity of these findings varies between clinical reports, and a systematic multiple-case clinicopathological correlative analysis has not been performed to date.

The degree of spleen stiffness measured on acoustic radiation force impulse elastography predicts the severity of portal hypertension in patients with biliary atresia after portoenterostomy.

Background/purpose: Acoustic radiation focus impulse (ARFI) elastography is a new method for assessing the degree of tissue stiffness. We herein evaluated the degree of spleen stiffness (SS) using ARFI elastography in patients with biliary atresia (BA) after Kasai portoenterostomy (KPE).

Methods: We retrospectively collected the liver stiffness (LS) and SS values on ARFI elastography from 43 patients undergoing KPE between September 2010 and November 2013.

Comparison of patients with Kawasaki disease with retropharyngeal edema and patients with retropharyngeal abscess.

Unlabelled: Kawasaki disease with retropharyngeal edema (KD with RPE) is a rare complication, and it is diagnosed by neck CT. Most reported cases had a delayed diagnosis because those patients' conditions were misdiagnosed as retropharyngeal abscess (RPA). The purpose of this study was to differentiate KD with RPE from RPA.

Olive oil enema in a pre-term infant with milk curd syndrome.

Milk curd syndrome was first reported in the 1960s, but was gradually forgotten because of its low incidence thereafter. This condition in pre-term infants has been reported over the last decade and has again attracted neonatologists' attention. The present report describes a pre-term infant with milk curd syndrome.

Living donor liver transplantation for multiple intrahepatic portosystemic shunts after involution of infantile hepatic hemangiomas.

We describe a 6-year-old girl presenting with multiple intrahepatic portosystemic shunts after the involution of infantile hepatic hemangiomas (IHHs), who successfully underwent living donor liver transplantation. The chronological changes of radiologic findings indicated that remnant portovenous shunts at the time of IHHs involution developed gradually on the background of atrophic intrahepatic portal veins. This suggests that patients should be carefully followed up for the late onset of intrahepatic portosystemic shunts after the involution of IHHs.

CT and MR imaging for pediatric cochlear implantation: emphasis on the relationship between the cochlear nerve canal and the cochlear nerve.

Background: Cochlear implantation has become an accepted treatment for deafness. As the frequency of cochlear implantation has increased, requests for images have also increased in the work-up for candidates. An absent cochlear nerve (CN) is a contraindication to cochlear implantation.
