Symptomatic congenital hemangiomatosis in a neonate: Imaging of a life-threatening presentation with multifocal liver involvement.

Hemangiomas are the most common benign vascular neoplasms of infancy. Congenital hemangiomas proliferate in utero, and are fully formed at birth. They are usually solitary. Generalized forms are exceptional. The liver is the second most common site of hemangiomas after the skin. When >5 cutaneous hemangiomas are present, screening abdominal ultrasound is recommended. Based on the degree of liver parenchyma involvement, 3 hepatic hemangiomas' subtypes are defined: focal, multifocal, and diffuse. Hepatic hemangiomas' clinical presentation varies from asymptomatic to life-threatening. High output cardiac failure, consumptive coagulopathy, abdominal compartment syndrome, and liver dysfunction are possible complications. We report an unusual case of symptomatic congenital hemangiomatosis in a male infant born with innumerable generalized cutaneous hemangiomas whose screening abdominal ultrasound revealed multifocal hepatic hemangiomas with extensive mixed shunts. We aim to highlight this unique entity with severe associated complications and stress the role of imaging at initial presentation, for follow-up, and to guide therapeutic choices.

Frequency of Drug Induced Acute Kidney Injury in Pediatric Intensive Care Unit.

BACKGROUND: Acute kidney injury (AKI) is known to complicate one-third of cases in pediatric intensive care units (PICU), and almost one-fourth of these are due to nephrotoxic drugs (NTDs). Although stopping NTDs seems the most obvious option, it is not practically applicable. Many NTDs are the only existing option, and their potential benefits outweigh the risk of drug-induced AKI. OBJECTIVES: To assess the proportion of children receiving NTDs in the PICU and highlight the children who developed AKI. METHODS: A prospective observational study was conducted in the PICU of the National Institute of Child Health, Karachi. All children admitted to the PICU for at least 72 hours not diagnosed with any acute or chronic kidney disease were included. Serum creatinine (SCr) was done at admission and then after 72 hours. Data was entered and analyzed using IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp. RESULTS: Of 99 children, 53 (53.5%) were male. NTD exposure was positive in 97 (97.9%), and 72 (72.7%) had high exposure (≥3 NTDs). Drug-induced AKI was diagnosed in 46 (46.5%). It was significantly related to high SCr even at admission and high NTDs exposure. The mortality rate in the AKI group was 17% compared to 4% in the non-AKI (p=0.02). CONCLUSION: Almost half of all PICU admissions were infants. Almost all patients were exposed to NTDs, and three-fourth experienced high exposure. AKI developed in 46% of patients and may be predicted by raised creatinine at the time of admission. Children exposed to ≥3 NTDs had a higher chance of drug-induced AKI.

Toxicity testing of indocyanine green and fluorodeoxyglucose conjugated iron oxide nanoparticles with and without exposure to a magnetic field.

Iron nanoparticles (MNPs) are known to induce membrane damage and apoptosis of cancer cells. In our study we determined whether FDG coupled with iron oxide magnetic nanoparticles can exert the same destructive effect on cancer cells. This research study presents data involving NIC-H727 human lung, bronchus epithelial cells exposed to conjugated fluorodeoxyglucose conjugated with iron-oxide magnetic nanoparticles and indocyanine green (ICG) dye (FDG-MNP-ICG), with and without the application of a magnetic field. Cell viability inferred from MTT assay revealed that FDG-MNPs had no significant toxicity towards noncancerous NIC-H727 human lung, bronchus epithelial cells. However, percentage cell death was much higher using a magnetic field, for the concentration of FDG-MNP-ICC used in our experiments. Magnetic field was able to destroy cells containing MNPs, while MNPs alone had significantly lower effects. Additionally, MNPs alone in these low concentrations had less adverse effects on healthy (non-target) cells.

Expanding the phenotypes of congenital hemangiomas.

Congenital hemangiomas (CH) are benign vascular tumors that are present at birth and do not stain for the marker Glut-1. Herein, we describe five cases of CH with atypical presentations: 3 with late growth, 1 with slow involution, and 1 that partially involuted rapidly then manifested late growth.

Congenital hemangioma exhibiting postnatal growth.

Congenital hemangiomas are vascular tumors that are fully formed at birth, typically without postnatal growth. Noninvoluting congenital hemangiomas (NICH) have a distinctive clinical, radiologic, and histopathological profile and lack of expansion or involution over time. Herein, we describe two cases of NICH with atypical postnatal growth.

Recent advances in understanding intestinal stem cell regulation.

Intestinal homeostasis and regeneration are driven by intestinal stem cells (ISCs) lying in the crypt. In addition to the actively cycling ISCs that maintain daily homeostasis, accumulating evidence supports the existence of other pools of stem/progenitor cells with the capacity to repair damaged tissue and facilitate rapid restoration of intestinal integrity after injuries. Appropriate control of ISCs and other populations of intestinal epithelial cells with stem cell activity is essential for intestinal homeostasis and regeneration while their deregulation is implicated in colorectal tumorigenesis. In this review, we will summarize the recent findings about ISC identity and cellular plasticity in intestine, discuss regulatory mechanisms that control ISCs for intestinal homeostasis and regeneration, and put a particular emphasis on extrinsic niche-derived signaling and intrinsic epigenetic regulation. Moreover, we highlight several fundamental questions about the precise mechanisms conferring robust capacity for intestine to maintain physiological homeostasis and repair injuries.

NICH at Its Best for Diabetes at Its Worst: Texting Teens and Their Caregivers for Better Outcomes.

BACKGROUND: There is growing evidence for the feasibility of text-based interventions for pediatric patients with type 1 diabetes (T1D). However, less is known regarding whether the use of personalized text messages with high-risk youth and their caregivers is associated with improvements in youth health. This study examines the use of diabetes-specific texts and associated health outcomes for participants of the Novel Interventions in Children's Healthcare (NICH) program. METHODS: Text messages sent to youth with T1D and their caregivers during NICH intervention were coded regarding diabetes relevance and adherence-related content. Health outcome data (eg, HbA1c values, hospital admissions) prior to and following NICH program enrollment were collected. RESULTS: Fewer than half (43%) of texts sent to patients and their caregivers were identified as being related to diabetes, and over 95% of diabetes-related texts were identified as adherence-related. Participants in the NICH program demonstrated a significant decrease in HbA1c values, t(23) = 2.78, p ≤ .05, and DKA-related hospital visits, t(24) = 2.78, p ≤ .01, during program involvement. Although no relationships were identified between patient-recipient text characteristics and health outcomes, the frequency and type of text messaging with caregivers was significantly associated with changes in health outcomes. CONCLUSIONS: This study represents the most extensive evaluation of diabetes-related SMS use and health outcomes for NICH participants to date. Findings demonstrate improvements in patient health during NICH program involvement. Implications include that sending frequent, personalized, and adherence-reinforcing texts to patients' caregivers may result in improved patient health, decreased utilization, and, potentially, associated reductions in health care costs.

Minor Nonintracranial Hemorrhage and Poor Prognosis among Stroke Patients Undergoing Intravenous Thrombolysis.

BACKGROUND: Whether nonintracranial hemorrhage (NICH) associated with intravenous thrombolysis (IVT) is a predictor of intracranial hemorrhage (ICH) and poor prognosis is ambiguous. We sought to analyze the rate of NICH and the relationship between NICH and poor outcome in the ischemic stroke population undergoing IVT. METHODS: This is a single-center, hospital-based prospective study. All ischemic stroke patients undergoing IVT between December 2015 and November 2016 were included. NICH was defined according to the criteria of the Bleeding Academic Research Consortium (BARC). ICH associated with IVT was defined based on the European Cooperative Acute Stroke Study II definition. On the basis of the modified Rankin Scale (mRS), 90-day outcome was divided into favorable outcome (mRS score 0-1) versus unfavorable outcome (mRS score 2-6) and independency (mRS score 0-2) versus dependency and death (mRS score 3-6). RESULTS: A total of 212 patients undergoing IVT were included in the analysis. Forty-five NICH events were reported in 42 patients (19.8%). Older age was independently associated with NICH (P = .049, odds ratio [OR] = .97, 95% confidence interval [CI] .94-1.0). Neither NICH with BARC class 1 or higher (P = .56, OR = .61, 95% CI .11-3.24) nor NICH with BARC class 2 or higher (P = .87, OR = 1.19, 95% CI .14-10.23) was associated with ICH. NICH with BARC class 1 or higher was not associated with unfavorable outcome (P = .67, OR = 1.17, 95% CI .56-2.45) and dependence and death (P = .47, OR = .72, 95% CI .30-1.75), neither was NICH with BARC class 2 or higher (P = .97, OR = 1.02, 95% CI .46-2.27 and P = .30, OR = .59, 95% CI .22-1.62). CONCLUSIONS: NICH was common among ischemic stroke populations receiving IVT. NICH with BARC class 2 or lower was not associated with ICH and poor outcome.

Partnering with Insurers in Caring for the Most Vulnerable Youth with Diabetes: NICH as an Integrator.

PURPOSE OF REVIEW: In this review, we outline barriers to appropriately caring for high-risk youth with diabetes and discuss efforts in partnering with insurers through Alternative Payment Models to achieve the Triple Aim (improved health, improved care, and reduced costs) for this population. RECENT FINDINGS: Current approaches in caring for youth with diabetes who evidence a high degree of social complexity are woefully ineffective. These youth are vulnerable to repeat diabetic ketoacidosis episodes, poor glycemic control, and excessive utilization of healthcare resources. To effectively pursue the Triple Aim, an "integrator" (i.e., an entity that accepts responsibility for all components of the Triple Aim for a specified population) must be identified; however, this does not fit into current fee-for-service models. Integrators for youth with diabetes are limited, but early examples of integrator efforts are promising. We present one successful "integrator," Novel Interventions in Children's Healthcare (NICH), and detail this program's efforts in partnering with insurers to serve high-risk youth with diabetes.

Possible toxicity following embolization of congenital giant vertex hemangioma: case report.

The authors describe the case of a 3-year-old boy with a giant congenital vertex hemangioma who underwent presurgical embolization with Onyx (ethylene-vinyl alcohol copolymer dissolved in dimethyl sulfoxide) and Glubran ( N-butyl-2-cyanoacrylate). This vascular tumor had no intracranial vascular communication as assessed by pre-embolization MRI and catheter angiography. All embolizations were performed by direct percutaneous injection. One week following the last embolization procedure the child presented with a 24-hour history of ataxia and extrapyramidal tremor. He was diagnosed with a possible immune-mediated reaction to Onyx or Glubran, which was treated with an urgent surgical excision of the hemangioma followed by intravenous administration of immunoglobulin and steroids. To the authors' knowledge, this is the first case of possible immune-mediated toxicity secondary to either Onyx or Glubran administration. This case highlights the need for awareness of potential toxic reactions to these embolic agents in the treatment of hemangiomas in the pediatric patient.

Congenital hemangiomas.

Congenital hemangiomas are rare solitary vascular tumors that do not proliferate after birth. They are characterized as either rapidly involuting congenital hemangiomas (RICHs) or noninvoluting congenital hemangiomas (NICHs) based on their clinical progression. NICHs have no associated complications, but are persistent. RICH, while usually asymptomatic, may ulcerate or bleed early in their presentation, but involute quickly during the first few months of life. Hepatic RICHs are not associated with cutaneous RICHs, but may result in high-output cardiac failure due to arteriovenous or portovenous shunting. In the following review, the clinical characteristics and current management specific to congenital hemangiomas is discussed.

Texting Adolescents in Repeat DKA and Their Caregivers.

BACKGROUND: Text message interventions are feasible, preferable, and sometimes effective for youth with diabetes. However, few, if any studies, have examined the personalized use of text messages with youth repeatedly hospitalized for diabetic ketoacidosis (DKA) and their caregivers. This study characterizes the use of personalized text messages in Novel Interventions in Children's Healthcare (NICH). METHODS: Approximately 2 months of text messages sent to youth with repeat DKA and their caregivers were logged regarding the following text characteristics: (1) content, (2) intervention type, (3) timing, and (4) recipient characteristics. RESULTS: NICH interventionists sent 2.3 and 1.5 texts per day to patients and caregivers, respectively. Approximately 59% of outgoing texts occurred outside of typical business hours, and roughly 68% of texts contained some form of support and/or encouragement. The relation between type of intended intervention and day/time of text was significant, χ(2)(2, N = 5,808) = 266.93, P < .001. Interventionists were more likely to send behavioral intervention text messages outside of business hours, whereas they were more likely to send care coordination and case management text messages during business hours. CONCLUSIONS: To our knowledge, this is the first study to specifically categorize and describe the personalized use of text messages with youth repeatedly hospitalized for DKA and their caregivers. Findings indicate that a promising treatment program for these youth frequently used text interventions to deliver praise and encouragement to patients and caregivers alike, often outside of typical business hours, and tailored text content based on patient and caregiver characteristics.

Isoprenaline Induces Periostin Expression in Gastric Cancer.

PURPOSE: Periostin mediates critical steps in gastric cancer and is involved in various signaling pathways. However, the roles of periostin in promoting gastric cancer metastasis are not clear. The aim of this study was to investigate the relevance between periostin expression and gastric cancer progression and the role of stress-related hormones in the regulation of cancer development and progression. MATERIALS AND METHODS: Normal, cancerous and metastatic gastric tissues were collected from patients diagnosed with advanced gastric cancer. The in vivo expression of periostin was evaluated by in situ hybridization and immunofluorescent staining. Meanwhile, human gastric adenocarcinoma cell lines MKN-45 and BGC-803 were used to detect the in vitro expression of periostin by using quantitative real-time polymerase chain reaction (PCR) and western blotting. RESULTS: Periostin is expressed in the stroma of the primary gastric tumors and metastases, but not in normal gastric tissue. In addition, we observed that periostin is located mainly in pericryptal fibroblasts, but not in the tumor cells, and strongly correlated to the expression of α-smooth muscle actin (SMA). Furthermore, the distribution patterns of periostin were broader as the clinical staging of tumors progressed. We also identified a role of stress-related signaling in promoting cancer development and progression, and found that isoprenaline upregulated expression levels of periostin in gastric cancer cells. CONCLUSION: These findings suggest that the distribution pattern of periostin was broader as the clinical staging of the tumor progressed and found that isoprenaline upregulated expression levels of periostin in gastric cancer cells.
