Objectives: We aimed to determine whether the occurrence of early-onset toxicities due to 5-fluorouracil (5-FU) in treatment-naive patients undergoing their first cycle of FOLFOX/FOLFIRINOX was associated with decreased overall survival, increased risk of treatment cessation, and hospitalization.

Methods: This was a retrospective cohort study using patient information from community oncology practices. Patients who received their first dose of 5-FU from 1 January 2015 through 1 August 2023 were included.

Article Synopsis
  • High-dose methotrexate (HDMTX) can cause acute kidney injury (AKI), making early detection crucial to prevent further damage.
  • A study analyzed MTX elimination patterns as potential biomarkers for AKI in patients undergoing HDMTX treatment, utilizing ROC curves to identify significant markers.
  • Results showed that early MTX elimination times are linked to AKI risk, suggesting that monitoring these patterns can help tailor patient care, including hydration and treatment adjustments.

Primary central nervous system lymphoma (PCNSL) is a highly aggressive non-Hodgkin lymphoma that is confined within the CNS. Due to its ability to cross the blood-brain barrier, high-dose methotrexate (HDMTX) is the backbone for induction chemotherapy. This systematic review was conducted to observe outcomes among different HDMTX doses (low, <3 g/m; intermediate, 3-4.

Background: Transverse myelitis (TM) in childhood is a rare disorder characterized by the presence of spinal cord inflammation. Gait difficulty in children with TM is common; however, there is a paucity of literature regarding quantitative assessment of gait in children and adolescents with TM.

Objectives: To characterize gait patterns in a cohort of ambulatory children with TM and age-matched, typically developing peers in order to better understand the functional mobility of patients diagnosed with childhood TM.

Study Design: International focus groups.

Objectives: The objective of this project was to develop the International Spinal Cord Injury (SCI) Pediatric Activity and Participation (A&P) Basic Data Set.

Methods: A focus group of experts in pediatric and adult SCI, and contributors of the existing adult International SCI Adult A&P Basic Data Set convened to develop an initial draft of the data set, which was iteratively refined over a 12 month period based on relevant literature and existing outcome measures that evaluate pediatric activity and participation.

Objectives: To describe long-term outcomes of neurogenic bowel dysfunction (NBD), determine changes over time in the type of bowel program, and determine changes in psychosocial outcomes associated with NBD-related factors in adults with pediatric-onset spinal cord injury (SCI).

Design: Longitudinal cohort survey. Follow-up occurred annually for a total of 466 interviews, with most participants (75%) contributing to at least 3 consecutive interviews.

Background: Employment rates among individuals with spinal cord injury (SCI) are lower than in the general population and little is known about the specific occupations in which they are employed.

Objectives: To describe specific occupations of adults with pediatric-onset SCI using the 2010 Standard Occupational Classification (SOC) system and to determine associations between SOC occupations and demographic factors.

Methods: Cross-sectional data specific to education and employment were collected from the last interviews of a larger longitudinal study.

Background: Cardiovascular measures in children with spinal cord injury (SCI) may vary depending on the child's age and physical development in addition to injury-related factors. Developmental changes should be considered when addressing cardiovascular complications in this population.

Objectives: To determine baseline blood pressure (BP) and heart rate (HR) measurements in youth with SCI, and to investigate differences in BP and HR in relation to age, gender, body mass index (BMI), and injury-related factors.

Objective: The purpose of this manuscript is to present a general overview and preliminary results of pilot projects of two complications in pediatric spinal cord injury (SCI): autonomic cardiovascular dysfunction and vitamin D deficiency.

Methods: Retrospective cross-sectional investigations of blood pressures (BP), heart rates (HR), and vitamin D levels were performed.

Results: Among 279 children with SCI, it was observed that baseline BP increases and HR decreases with increasing age.

Objective: To evaluate the psychometric properties of the Care and Comfort Caregiver Questionnaire (CareQ), which was developed to measure the perceived effort of caregivers in providing care for children with moderate to severe cerebral palsy (CP).

Design: Cross-sectional data collection from a representative sample of a large racially/ethnically diverse geographic region.

Setting: Outpatient CP clinics at a metropolitan rehabilitation institution.

Biomechanical properties of calf muscles and Achilles tendon may be altered considerably in children with cerebral palsy (CP), contributing to childhood disability. It is unclear how muscle fascicles and tendon respond to rehabilitation and contribute to improvement of ankle-joint properties. Biomechanical properties of the calf muscle fascicles of both gastrocnemius medialis (GM) and soleus (SOL), including the fascicle length and pennation angle in seven children with CP, were evaluated using ultrasonography combined with biomechanical measurements before and after a 6-wk treatment of passive-stretching and active-movement training.

Background: Ankle impairments are closely associated with functional limitations in children with cerebral palsy (CP). Passive stretching is often used to increase the range of motion (ROM) of the impaired ankle. Improving motor control is also a focus of physical therapy.

The current study introduces a novel rehabilitation robot for treatment of impaired ankle in children with cerebral palsy (CP). The treatment consisted of passive stretching under intelligent control and active movement training with motivating game-playing using the portable robot. After 18 sessions of training (3 sessions/week for 6 weeks), we found significant improvement in 12 children with CP in terms of improved passive and active ranges of motion, selective motor control and mobility functions.

Intramuscular hemangioma, an infrequent but important cause of musculoskeletal pain, is often difficult to establish the diagnosis clinically. This report describes a case of a 32-yr-old woman who presented with severe left calf pain for 10 yr. Initial conservative treatments consisting of intramuscular electrical stimulation, herb medication, acupuncture, and intramuscular lidocaine injection under the diagnosis of myofascial pain syndrome in other facilities, failed to alleviate the symptoms.

"Hip-huggers" may be a precipitating factor for meralgia paresthetica (MP), especially in thin persons with an aberrant pathway of the lateral femoral cutaneous nerve (LFCN). We describe a 25-year-old woman with a long-standing history of MP caused by an abnormal course of the LFCN and tight trousers, specifically hip-huggers. Ultrasonography was useful for detecting the lesion site and the abnormal pathway of the LFCN.
