Tumor-induced osteomalacia (TIO) is caused by the hormone fibroblast growth factor 23 (FGF-23). It is mainly produced in the tissue of mesenchymal tumors. Patients with TIO frequently suffer from a chronic decompensated pain syndrome and/or muscle weakness with postural deformity. Despite the severity of the disease, the diagnosis is frequently established late. In some cases, it takes several years to establish the condition. This case report concerning a 68-year old woman demonstrates the selective blood sampling for FGF-23 as path-breaking diagnostics to confirm the diagnosis of a neuroendocrine tumor...

The advent of hybrid cameras that combine magnetic resonance imaging with either single-photon emission computed tomography (SPECT/MRI) or positron-emission tomography (PET/MRI) has stimulated growing interest in developing multi-modality imaging probes. Countless options are available for fusing magnetically active species with positron- or gamma-ray emitting radionuclides. The initial problem is one of choice: which chemical systems are a suitable basis for developing hybrid imaging agents? Any attempt to answer this question must also address how the physical, chemical, and biological properties of a unified imaging agent can be tailored to ensure that optimum specificity and contrast is achieved simultaneously for both imaging modalities...

An 18-year-old Caucasian man presented with a lack of sense of surrounding smell. The problem was first noticed when a family member discussed the smell of the food, which he had no idea what it was. The patient had normal development and sexual function, no history of trauma, surgery, chemical exposure or infection. Physical examination revealed no significant abnormalities. Smell threshold test using phenyl-ethyl-alcohol revealed bilateral anosmia. MRI showed bilateral aplastic olfactory bulbs and tracts associated with absent cortical growth of the olfactory sulci and asymmetrical gyrus rectus...

Here we examined neural substrates for physically and observationally learning to construct novel objects, and characterized brain regions associated with each kind of learning using fMRI. Each participant was assigned a training partner, and for five consecutive days practiced tying one group of knots ("tied" condition) or watched their partner tie different knots ("watched" condition) while a third set of knots remained untrained. Functional MRI was obtained prior to and immediately following the week of training while participants performed a visual knot-matching task...

A 9-month-old female Weimaraner was presented to the emergency service due to episodes of fever and neck pain. Physical examination revealed a stiff neck posture and elevated body temperature. Shortly after clinical examination was performed, the dog developed peracute onset of non-ambulatory tetraparesis compatible with a C1-C5 spinal cord (SC) lesion. Immediately thereafter (<1 h), MRI of the cervical SC was performed with a 3-T scanner. A left ventrolateral intradural-extramedullary SC compression caused by a round-shaped structure at the level of C3--C4 was evidenced...

Polyarteritis nodosa (PAN) is a medium vessel vasculitis affecting systemic organs. Muscle involvement of PAN usually lacks elevation of creatinine kinase (CK). We herein report a case of PAN with rhabdomyolysis. A 71-year-old man was hospitalized because of muscle weakness of the lower limbs that persisted for 1 month. On a physical examination, rapidly progressive lower proximal muscle weakness and bilateral drop foot were observed. His blood test showed an elevation in the C-reactive protein (CRP) (19.5 mg/dL) and CK (13,435 IU/L) levels and negativity for anti-neutrophilic cytoplasmic antibody (ANCA)...

BACKGROUND: Iron based ferromagnetic nanoparticles (IONP) have found a wide range of application in microelectronics, chemotherapeutic cell targeting, and as contrast enhancers in MRI. As such, the design of well-defined monodisperse IONPs is crucial to ensure effectiveness in these applications. Although these nanostructures are currently manufactured using chemical and physical processes, these methods are not environmentally conducive and weigh heavily on energy and outlays. Certain microorganisms have the innate ability to reduce metallic ions in aqueous solution and generate nano-sized IONP's with narrow size distribution...

The diagnosis of multiple sclerosis (MS) is based on a history consistent with demyelination of the central nervous system and corresponding physical signs on examination. However, this diagnosis is supported radiologically using magnetic resonance imaging (MRI). At present, MRI serves as the most reliable and widely available biomarker for the practising clinician to measure disease activity and treatment response in MS. As MRI remains central to both the diagnosis and management of MS, this paper provides proposed guidelines for its use in routine clinical practice...

BACKGROUND: Hemodynamic balance in the heart-brain axis is increasingly recognized as a crucial factor in maintaining functional and structural integrity of the brain and thereby cognitive functioning. Patients with heart failure (HF), carotid occlusive disease (COD), and vascular cognitive impairment (VCI) present themselves with complaints attributed to specific parts of the heart-brain axis, but hemodynamic changes often go beyond the part of the axis for which they primarily seek medical advice...

BACKGROUND: Gartner duct cysts are embryologic remnants of the mesonephric ducts that may present as a vaginal mass or cyst. CASE: A patient was referred for surgical management of prolapse whose bulging anterior vagina was actually a Gartner duct cyst that required excision as a result of symptoms. Preoperative magnetic resonance imaging helped confirm the diagnosis. CONCLUSION: A Gartner duct cyst may present as a vaginal cyst that, if large, may mimic pelvic organ prolapse...

Since centuries, scientists, clinicians and philosophers have been debating about the interactions between the body and the mind. Researches and advances in neurophysiology over the last decades have challenged many principles and theories, mainly based on empirical observations, generally well accepted in clinical practice. These new findings, achieved through functional "magnetic resonance imaging", awake brain surgery and allow new techniques and opportunities in physical rehabilitation. More than ever the body and the brain must be considered and treated as a functional entity, the distinction between body and soul developed by Platon should no longer be applied...

As the incidence of anterior cruciate ligament (ACL) reconstruction continues to increase, the rate of revision surgery continues to climb. Revision surgery has inherent challenges that must be addressed in order to achieve successful results. The cause of the primary ACL reconstruction failure should be determined, and careful preoperative planning should be performed to address the cause(s) of failure. Each patient undergoing revision surgery should undergo a thorough history and physical examination, receive full length alignment radiographs, lateral radiographs, 45-degree flexion weight-bearing postero-anterior radiographs, and patellofemoral radiographs...

The scientific study of human consciousness has greatly benefited from the development of non-invasive brain imaging methods. The quest to identify the neural correlates of consciousness combined psychophysical experimentation with neuroimaging tools such as functional magnetic resonance imaging (fMRI) to map the changes in neural activity associated with conscious vs. unconscious percepts. Different neuroimaging methods have also been applied to characterize spontaneous brain activity fluctuations during altered states of consciousness, and to develop quantitative metrics for the level of consciousness...

Prevention of dementia due to Alzheimer's disease (d/AD) requires interventions that slow the disease process prior to symptom onset. To develop such interventions, one needs metrics that assess pre-symptomatic disease progression. Familiar measures of progression include cerebrospinal fluid (CSF) biochemical and imaging analyses, as well as cognitive testing. Changes in the latter can sometimes be difficult to distinguish from effects of "normal" aging. A different approach involves testing of "central auditory processing" (CAP), which enables comprehension of auditory stimuli amidst a distracting background (e...

Large-scale intrinsic brain systems have been identified for exteroceptive senses (e.g., sight, hearing, touch). We introduce an analogous system for representing sensations from within the body, called interoception, and demonstrate its relation to regulating peripheral systems in the body, called allostasis. Employing the recently introduced Embodied Predictive Interoception Coding (EPIC) model, we used tract-tracing studies of macaque monkeys, followed by two intrinsic functional magnetic resonance imaging samples (N = 280 and N = 270) to evaluate the existence of an intrinsic allostatic/interoceptive system in the human brain...

Value-based care emphasizes achieving the greatest overall health benefit for every dollar spent. We present an interesting case of stroke, which made us consider how frequently health care providers are utilizing value-based care. A 73-year-old Caucasian, who was initially admitted for a hypertensive emergency, was transferred to our facility for worsening slurring of speech and left-sided weakness. The patient had an extensive chronic cerebrovascular disease, including multiple embolic type strokes, mainly in the distribution of the right temporal-occipital cerebral artery and transient ischemic attacks (TIAs)...
