Understanding the histogenesis of a HRAS-PIK3R1 co-driven metastatic metaplastic breast carcinoma associated with squamous metaplasia of lactiferous ducts.

Metaplastic breast carcinoma (MBC) represents a heterogeneous group of aggressive primary breast cancers that can show differentiation into carcinomatous and sarcomatous elements. Due to its rapid growth, this malignancy can replace precursor lesions, which remain unknown in most cases. Herein, we describe a MBC presenting as a deceptive post-biopsy hematoma.

A clinicopathological study of fibroadenomas with epithelial proliferation including lobular carcinoma in-situ, atypical ductal hyperplasia, DCIS and invasive carcinoma.

Background: Fibroadenoma is a benign mixed tumor composed of epithelial and non-epithelial components. The epithelial component of a fibroadenoma may exhibit proliferation, including lobular carcinoma in-situ, atypical ductal hyperplasia, DCIS and rarely, invasive breast carcinoma.

Objective: In this series of 30 cases of fibroadenoma with epithelial proliferation, we assessed the radiological and histopathological findings of each entity.

Automated whole breast ultrasound.

Bilateral whole breast (screening) ultrasound has been well established in multiple single- and multi-institution published studies as a valuable adjunct to mammography screening for early detection of breast cancer. However, implementation of screening breast ultrasound programs has been limited and has met with resistance because of the number of potential false positives generated by ultrasound screening, and the lack of available personnel to perform the examination. Automated breast ultrasound, which has recently been approved by the US Food and Drug Administration for use in whole-breast ultrasound screening, is a potential option for providing breast ultrasound screening on a widespread basis.

Solitary neurofibroma of the breast.

Neurofibromas are slow-growing, painless, benign nerve-sheath tumors. They occur most commonly in the dermis and subcutis and are rarely found in the breast. We report a rare case of a solitary neurofibroma of the breast in a 61-year-old asymptomatic woman.

The use of research measures in adult clinical practice.

Many psychopathology research assessment tools can be used easily and productively in clinical practice. We conducted a workshop in 2009 and 2010 at the American Psychiatric Association annual meeting designed to bring clinicians some commonly used adult research measures with broad applicability to a variety of conditions. This article reviews what was most helpful to the practicing clinicians at the workshop.

The History and Accomplishments of the LIVESTRONG Young Adult Alliance.

Purpose: This article outlines the history, background, and accomplishments of the LIVESTRONG Young Adult Alliance.

Background: The LIVESTRONG Young Adult Alliance, a program of the Lance Armstrong Foundation, was developed as a vehicle for a strategic plan designed to implement the Adolescent and Young Adult Oncology Progress Review Group (AYAO PRG) recommendations. The AYAO PRG was co-sponsored by Lance Armstrong Foundation and the National Cancer Institute (NCI); both LIVESTRONG and NCI provide strategic oversight and guidance to the Alliance.

ACR Appropriateness Criteria® on nonpalpable mammographic findings (excluding calcifications).

Screening mammography can detect breast cancer before it becomes clinically apparent. However, the screening process identifies many false-positive findings for each cancer eventually confirmed. Additional tools are available to help differentiate spurious findings from real ones and to help determine when tissue sampling is required, when short-term follow-up will suffice, or whether the finding can be dismissed as benign.

To foster healing among adolescents and young adults with cancer: what helps? What hurts?

Purpose: The physical and emotional well-being of adolescents and young adults with cancer (AYA) rests on the ability of all concerned to promote helpful forms of care and reduce hurtful forms. The purpose of this study was to identify aspects of behavior that may promote or inhibit healthy psychosocial adjustment for this age-defined population.

Method: Seventeen young adult cancer survivors participated in focus groups to discuss what people said or did that they found helpful or hurtful.

Emotional expression in children treated with ADHD medication: development of a new measure.

Objective: Although existing instruments contain items addressing the effect of ADHD medications on emotional expression, a review of measures did not yield any instruments that thoroughly evaluated positive and negative aspects of emotional expression.

Method: The Expression and Emotion Scale for Children (EESC), a parent-report measure, was developed from an analysis of qualitative data from parent focus groups and expert opinion. Data from 179 parents and children treated with stimulants or atomoxetine are used to examine the psychometric properties of the EESC.

Efficacy and safety of atomoxetine in adolescents with attention-deficit/hyperactivity disorder and major depression.

This double-blind study examined efficacy and safety of atomoxetine (ATX; < or =1.8mg/kg per day) in adolescents aged 12-18 with Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) diagnoses of both attention-deficit/hyperactivity disorder (ADHD) and co-morbid major depressive disorder (MDD). Diagnoses were confirmed by the Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version and persistently elevated scores on the Attention-Deficit/Hyperactivity Disorder Rating Scale-IV, Parent version, Investigator-administered and -scored (ADHDRS-IV-Parent:Inv, > or =1.

Neuroleptic malignant syndrome from aripiprazole in an agitated pediatric patient.

Objective: Neuroleptic malignant syndrome was induced by aripiprazole in a 12 1/2-year-old boy. The patient had a history of reactive airway disease, pervasive developmental disorder, and learning disability.

Method: The patient was interviewed and examined, and additional history was taken from the medical records.

Fluoxetine 40-60 mg versus fluoxetine 20 mg in the treatment of children and adolescents with a less-than-complete response to nine-week treatment with fluoxetine 10-20 mg: a pilot study.

Objective: The aim of this study was to compare fluoxetine dosage titration to 40-60 mg/day with fixed fluoxetine 20-mg/day treatment for an additional 10 weeks in pediatric outpatients with major depressive disorder (MDD) who had not met protocol-defined response criteria after 9-week acute fluoxetine treatment.

Methods: Patients unresponsive (less than or equal to 30% decrease in Children's Depression Rating Scale-Revised [CDRS-R] score) after 9-week fluoxetine treatment were randomly reassigned to continue at 20 mg/day or to increase to 40 mg/day. After 4 weeks, patients unresponsive to 40 mg/day could receive 60 mg/day.

Short-term efficacy of methylphenidate: a randomized, double-blind, placebo-controlled trial among survivors of childhood cancer.

Purpose: Children surviving acute lymphoblastic leukemia (ALL) and malignant brain tumors (BTs) have a higher incidence of attention and learning problems in school than do their healthy peers. The present study tests the hypothesis that the psychostimulant methylphenidate (MPH) improves cognitive and social functioning among these patients.

Patients And Methods: We report on 83 long-term survivors of ALL and BT identified as having attentional deficits on behavioral testing and parent or teacher report, and problems with academic achievement.

A model of care for childhood cancer survivors that facilitates research.

The majority of children and adolescents diagnosed with cancer will achieve long-term survival after contemporary therapy. Consequent to this success are challenges inherent in coordinating lifelong health care for a group predisposed to a variety of cancer-related complications. With increasing numbers of aging adult survivors of childhood cancer, clinicians now face the additional challenge of studying delayed effects of childhood cancer in the context of organ senescence.

Improvement in sensitivity of screening mammography with computer-aided detection: a multiinstitutional trial.

Objective: Our study evaluated radiologist detection of breast cancer using a computer-aided detection system.

Materials And Methods: Three radiologists reviewed 377 screening mammograms interpreted as showing normal or benign findings 9-24 months before cancer diagnosis from 17 of the 18 participating centers. In 313 cases, study radiologists recommended additional mammographic evaluation.

Wound fluid bacterial levels exceed tissue bacterial counts in controlled porcine partial-thickness burn infections.

In the present study, an established controlled burn wound model was used to test the hypothesis that controlled surface contamination with is capable of generating a noninvasive method for the creation of a reproducible deep tissue burn wound infection. Using a liquid tight-wound chamber in Yorkshire pigs, partial-thickness burns were inoculated with saline-immersed for 24 hours. Noninoculated burns and unwounded skin immersed in normal saline served as controls.

Intracranial infantile myofibromatosis with intraparenchymal involvement.

Infantile myofibromatosis is the most common fibrous disorder of infancy and early childhood. Intracranial involvement is rare, with the majority of lesions being localized to the skull or dura with variable intracranial extension. We present the case of a 19-month-old girl with infantile myofibromatosis and an incidentally discovered, enlarging, calcified, posterior fossa mass.
