Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established...

A hiccup is a reflex movement with diffusely distributed afferents and efferents in the thorax; its functional relevance is controversial. In its physiological form, it is mostly a minor complaint that stops spontaneously and rarely leads to medical consultation. However, prolonged agonizing hiccups represent serious deterioration of quality of life. Chronic hiccups by definition last for more than 48 h, with gastroesophageal reflux being the frequent underlying disease. Various other causes affect multiple organ systems, some with serious underlying diseases...

OBJECTIVE The treatment of cervical spinal metastases represents a controversial issue regarding the type, extent, and invasiveness of interventions. In the lumbar and thoracic spine, kypho- and vertebroplasties have been established as minimally invasive procedures for patients with metastases to the vertebral bodies and without neurological deficit. These procedures show good results with respect to pain reduction and low complication rates. However, limited data are available for kypho- and vertebroplasties for cervical spinal metastases...

PURPOSE: Benefits of minimally invasive neurosurgery mandate the development of ergonomic paradigms for neuronavigation. Augmented Reality (AR) systems can overcome the shortcomings of commercial neuronavigators. The aim of this work is to apply a novel AR system, based on a head-mounted stereoscopic video see-through display, as an aid in complex neurological lesion targeting. Effectiveness was investigated on a newly designed patient-specific head mannequin featuring an anatomically realistic brain phantom with embedded synthetically created tumors and eloquent areas...

Metastatic epidural spinal cord compression (MESCC) is an oncologic emergency requiring prompt treatment to maximize neurologic function, ambulatory function and local control. Traditionally, options for MESCC included external beam radiation therapy with or without surgery. Surgery has usually been reserved for the patient with optimal performance status, single level MESCC or mechanical instability. Advances in external beam radiation therapy such as the development of stereotactic body radiation therapy have allowed for the delivery of high-dose radiation, allowing for both long-term pain and local control...

G F Kolb
This article examines the question whether and how geriatrics will change in the future and whether in view of the demographic changes the trend will go more in the direction of a further expansion of geriatrics or more towards a geriatricization of individual specialist medical fields. The different development of geriatrics in the individual Federal States can only be understood historically and is absolutely problematic against the background of the new hospital remuneration system. Geriatrics is a typical cross-sectional faculty and still has demarcation problems with other faculties but has also not yet clearly defined the core competence...

RATIONALE AND OBJECTIVES: Anecdotal reports have recently surfaced of an increase in the number of US senior diagnostic radiology (DR)-bound residency applicants who did not secure a preliminary year position through the Main Resident Match (the Match) of the National Resident Matching Program (NRMP), so-called "partial matches." This study sought to determine the scope of this phenomenon and address potential causes and solutions. MATERIALS AND METHODS: Publicly available and proprietary data from the National Resident Matching Program were analyzed from 2005-2016 to determine the number of partially matched US senior applicants, selectivity of DR residency training, availability of preliminary year positions, number of unique preliminary year applicants, distribution of preliminary year matches by successfully matched applicants in relevant specialties (DR, anesthesiology, dermatology, neurology, physical medicine and rehabilitation, and radiation oncology), and percentage of categorical training programs participating in the Match...

BACKGROUND: There is increasing emphasis on using patient-reported outcomes (PROs) to complement traditional clinical outcomes in medical research, including in multiple sclerosis (MS). Research, particularly in oncology and heart failure, has shown that PROs can be prognostic of hard clinical endpoints such as survival time (time from study entry until death). However, unlike in oncology or cardiology, it is unknown whether PROs are associated with survival time in neurological diseases...

The history and physical examination are important keys to diagnosis and treatment of patients with chronic pelvic pain. The comprehensive history should include questioning regarding patient's pain complaint and a thorough history and review of any body system that may be involved, including neuromusculoskeletal, obstetric, gynecologic, gastrointestinal, urologic, dermatologic, infectious, oncologic, and psychiatric. The physical examination should also follow a focused systems-based approach and includes examination of gastrointestinal, dermatologic, neurologic, and musculoskeletal (including lumbosacral spine, sacroiliac joints, pelvis, and hips) systems, and the pelvic floor (internal and external examination, including neuromuscular anatomy)...

BACKGROUND: Von Hippel-Lindau (VHL) disease is a rare oncological disease with an incidence of 1:36,000, and is characterized by the growth of different types of tumours. Haemangioblastomas in the central nervous system (CNS) and retina, renal carcinoma and pheochromocytomas are the most common tumours. The absence of treatment for VHL leads to the need of repeated surgeries as the only option for these patients. Targeting VHL-derived tumours with drugs with reduced side effects is urgent to avoid repeated CNS surgeries...

A 57-year-old man presented to the surgical oncology clinic with a mildly tender mass under his right arm. Four years prior, the patient had a melanoma removed from his right shoulder along with an ipsilateral right axillary sentinel lymph sampling. Computed tomography (CT) scan was negative for metastatic disease at that time. The patient did not undergo completion axillary node dissection and was lost to follow-up. The patient was originally from Australia, did not tan but reported multiple sunburns before age 18...
