The promise of mobile technologies and single case designs for the study of individuals in their natural environment.

Mobile technologies are growing rapidly around the world to broad demographics of society. These technologies hold great promise for their integration with Single Case Designs (SCDs) and the study of individuals in their natural environment. This paper discusses the theoretical, methodological and analytic implications of these tools for the advancement of the contextual behavioral etiology of behavioral disorders, and their remediation.

The multidisciplinary management of giant cell tumor of bone.

Giant cell tumor of bone is a locally aggressive lesion with a predilection for local recurrence, and in a small proportion of patients, metastatic disease can develop. Surgery is the mainstay of management for extremity-based lesions. For tumors located in challenging anatomical locations such as the sacrum and spine however, surgery may be associated with unacceptable functional morbidity.

Long-term effect of depot medroxyprogesterone acetate on vaginal microbiota, epithelial thickness and HIV target cells.

Background: Depot medroxyprogesterone acetate (DMPA) has been linked to human immunodeficiency virus type 1 (HIV-1) acquisition.

Methods: Vaginal microbiota of women using DMPA for up to 2 years were cultured. Mucosal immune cell populations were measured by immunohistological staining.

Brentuximab vedotin in patients aged 60 years or older with relapsed or refractory CD30-positive lymphomas: a retrospective evaluation of safety and efficacy.

Older adults constitute a significant proportion of the cancer population, but are underrepresented in clinical trials. We conducted a retrospective analysis of the safety and efficacy of brentuximab vedotin in adults ≥ 60 years with relapsed CD30-positive lymphomas. Baseline characteristics and safety data were compared for older (median age 66) and younger patients (< 60 years, median age 32).

A Phase II multicenter, open-label, clinical and pharmokinetic trial of PM00104 in patients with advanced Ewing Family of Tumors.

Ewing sarcoma is a rare connective tissue tumor characterized by the translocation of the EWS gene, mainly between chromosome 11 and 22, giving rise to gene re-arrangements between the EWS gene and various members of the ETS gene family. Multi-agent chemotherapy has improved the outcome for patients with localized Ewing sarcoma, but survival of patients with recurrent/metastatic disease remains poor. An exploratory two-stage, single-arm Phase II multicenter trial of the synthetic alkaloid, PM00104, was conducted in patients with recurrent Ewing sarcoma.

Multidisciplinary approach to brain metastasis from melanoma; local therapies for central nervous system metastases.

The overall treatment paradigm for melanoma brain metastases continues to evolve and reflects the relative radioresistance of this histology, as well as the effect of emerging systemic therapies with central nervous system (CNS) activity. Local therapies, including surgery, whole brain radiotherapy (WBRT), and stereotactic radiosurgery (SRS), play an important role in the multidisciplinary management of melanoma brain metastases. Treatment selection for local therapies must consider many factors: (1) size, number, and location of lesions, (2) presence or absence of neurological symptoms, (3) extracranial disease status, expected survival, age, and performance status, (4) prior treatment history, (5) expected treatment toxicities, and (6) predicted response to systemic therapies.

Multidisciplinary approach to brain metastasis from melanoma: the emerging role of systemic therapies.

Melanoma brain metastases are common, difficult to treat, and carry a poor prognosis. Until recently, systemic therapy was ineffective. Local therapy (including surgery, stereotactic radiotherapy, and whole brain radiotherapy) was considered the only option for a chance of disease control in the brain, and was highly dependent on the patient's performance status and age, number and size of brain metastases, and the presence of extracranial metastases.

Galactomannan Antigen Testing for Diagnosis of Invasive Aspergillosis in Pediatric Hematology Patients.

Objective: Invasive aspergillosis (IA) can cause significant morbidity and mortality in immunocompromised children. The galactomannan (GM) enzyme immunoassay (EIA) has been shown in adult studies to be a useful adjunct in diagnosing IA. Data on this assay in children are limited by small sample sizes and conflicting results; false-positive assays were a concern in historical studies.

Diagnosis, prognosis, and management of leiomyosarcoma: recognition of anatomic variants.

Purpose Of Review: The purpose of this review is to present the most recent advances in the diagnosis of the more common leiomyosarcoma (LMS) anatomic variants, potentially useful prognostic markers that have recently been identified and the systemic approaches currently used or under evaluation to improve the outcome of patients with this disease.

Recent Findings: Over the last few years emphasis has been placed on incorporating effective imaging tools and using pathological biomarkers in the diagnostic workup of LMS. Moreover, efforts are being made to identify meaningful prognostic and predictive parameters that will aid the development of effective novel therapeutics.

Stem cell transplantation for multiple myeloma: current and future status.

Stem cell transplantation (SCT) has been used in the treatment of multiple myeloma (MM) for decades and has become a standard of care for newly diagnosed MM patients. However, several important questions remain regarding the optimal use of SCT, particularly in light of the many recent advances in the treatment of MM. Bortezomib-based therapy or, in some cases, lenalidomide-based therapy should be considered as an induction therapy in transplantation-eligible patients.

Targeted treatment for advanced soft tissue sarcoma: profile of pazopanib.

Soft tissue sarcomas comprise approximately 1% of all adult solid malignancies. While chemotherapy is the mainstay of treatment for patients with metastatic or inoperable disease, overall survival for these patients is approximately 12 months, highlighting the need for novel agents. Both laboratory and clinical data have suggested that antiangiogenic agents may have a role in the treatment of soft tissue sarcomas.

Management of gastrointestinal stromal tumors.

Gastrointestinal stromal tumors (GISTs) comprise <1% of all gastrointestinal tumors, but are the most common mesenchymal tumors of the GI tract. This review highlights the dramatic changes in clinical practice with regards to GIST in the last decade, with a focus on overall management and recent developments. For localized primary GISTs, surgical resection is the mainstay of therapy with the 5-year survival rate after complete resection averaging approximately 50-65%.

Epidemiology, Diagnosis, and Treatment of HIV-Associated Non-Hodgkin Lymphoma in Resource-Limited Settings.

Lymphoma was a common complication of HIV infection in the pre-antiretroviral era, and the incidence of HIV-associated lymphoma has dropped dramatically since the introduction of combination antiretroviral therapy (cART) in resource-rich regions. Conversely, lymphoma is an increasingly common complication of HIV infection in resource-limited settings where the prevalence of HIV infection is high. Relatively little is known, however, about the true incidence and optimal treatment regimens for HIV-associated lymphoma in resource-poor regions.

Long-term dynamics of bone mineral density during intermittent androgen deprivation for men with nonmetastatic, hormone-sensitive prostate cancer.

Purpose: To investigate changes in bone mineral density (BMD) and fracture risk in men who received intermittent androgen deprivation (IAD) for nonmetastatic, hormone-sensitive prostate cancer.

Patients And Methods: Men with prostate cancer who lacked radiographically detectable metastases were treated in a prospective trial of IAD. After 9 months of treatment with leuprolide and flutamide, androgen deprivation therapy (ADT) was stopped until prostate-specific antigen reached a threshold (1 ng/mL for radical prostatectomy; 4 ng/mL for radiation or primary ADT) for a new cycle.

Salvage therapy with single agent bendamustine for recurrent glioblastoma.

The treatment of recurrent glioblastoma (GBM) remains challenging notwithstanding the recent approval of bevacizumab for this indication. Bendamustine has a bifunctional mechanism of action including alkylation, penetrates the CNS and does not show cross resistance to other alkylator chemotherapies. In a single institution phase 2 trial, patients with recurrent GBM were treated with bendamustine (100 mg/m(2)/day administered intravenously for two consecutive days every 4 weeks).

Hydroxyurea for recurrent surgery and radiation refractory meningioma: a retrospective case series.

Hydroxyurea (HU), an orally administered chemotherapy, has become the de facto standard therapeutic agent in patients with surgically and radiation refractory meningiomas based on a limited literature. A retrospective case series of 60 patients with recurrent WHO grade 1 meningioma treated with HU following progression after surgery and radiotherapy was conducted with primary study objective progression free survival (PFS) at 6- and 12-months. Sixty patients (45 women; 15 men: median age 61.

Efficacy and safety of gemcitabine, carboplatin, dexamethasone, and rituximab in patients with relapsed/refractory lymphoma: a prospective multi-center phase II study by the Puget Sound Oncology Consortium.

We conducted a multi-center phase II trial of gemcitabine (G), carboplatin (C), dexamethasone (D), and rituximab (R) in order to examine its safety and efficacy as an outpatient salvage regimen for lymphoma. Fifty-one patients received 2-4 21-day cycles of G (1000 mg/m(2), days 1 and 8), C (AUC = 5, day 1), D (40 mg, daily days 1-4), and R (375 mg/m(2), day 8 for CD20-positive disease) and were evaluable for response. Characteristics included: median age 58 years (19-79 years), stage III/IV 88%, elevated LDH 33%, median prior therapies 2, prior stem cell transplant 12%, chemoresistant 62%, median prior remission duration 2.

"Could I add something?": Teaching communication by intervening in real time during a clinical encounter.

Supervising learners as they communicate often places faculty preceptors in a classic educational dilemma. What should a preceptor do when the learner is not communicating well and is not asking for help? What usually happens, in the authors' experiences, is that the preceptor decides at some point that she or he cannot stand the situation anymore-then interrupts the learner and takes over the conversation. Interrupting in this way, however, comes at the cost of undermining the learner.

Temozolomide for recurrent intracranial supratentorial platinum-refractory ependymoma.

Background: To the authors' knowledge, there currently is no standard therapy for platinum-resistant ependymoma; hence, a need exists for new therapies. In the current study, a retrospective evaluation of temozolomide (TMZ) in adults with recurrent, supratentorial, platinum-refractory, World Health Organization grade 2 ependymoma was performed, with an objective of determining 6-month progression-free survival (PFS).

Methods: A total of 25 patients, ages 28 to 63 years, with recurrent ependymoma were treated.

Temsirolimus in patients with advanced renal cell carcinoma: an overview.
