Reduced cardiac baroreceptor sensitivity (BRS) after acute stroke is associated with worse outcome. The underlying mechanisms of reduced BRS are unclear. We evaluated cross correlation BRS (xBRS) in 184 patients with suspected acute ischemic stroke within 72 h of symptom onset. Among these patients, 22 had a transient ischemic attack (TIA) and 27 had a stroke mimic. Sixty-four age- and sex-matched ambulant control subjects without stroke were included. Compared with controls, xBRS was significantly lower in patients with ischemic stroke, TIA, and stroke mimics (4...

Cobalt exposure in the hard metal and bonded diamond tool industry is a well-established cause of ILD. The primary theories regarding the underlying mechanism of cobalt related ILD include an immunologic mechanism and an oxidant injury mechanism. Cobalt related ILD may present in subacute and chronic forms and often has associated upper respiratory symptoms. The evaluation begins with a thorough occupational history and includes PFTs, HRCT, and bronchoalveolar lavage. HRCT findings are nonspecific and may resemble NSIP, UIP, sarcoidosis, or HP...

Our ability to use ionizing radiation as an energy source, as a therapeutic agent, and, unfortunately, as a weapon, has evolved tremendously over the past 120 years, yet our tool box to handle the consequences of accidental and unwanted radiation exposure remains very limited. We have identified a novel group of small molecule compounds with a 4-nitrophenylsulfonamide (NPS) backbone in common that dramatically decrease mortality from the hematopoietic acute radiation syndrome (hARS). The group emerged from an in vitro high throughput screen (HTS) for inhibitors of radiation-induced apoptosis...

María Soriano-Ramos, Enrique Salcedo Lobato, María Baro Fernández, Daniel Blázquez-Gamero
Langerhans cell histiocytosis in infants is a rare condition, and presentation as an isolated cervical adenitis is exceptional at this age. We describe the case of a 3-month-old female infant presenting with a neck mass in the right mandibular angle with poor response to antibiotic treatment. Fine needle aspiration was performed and confirmed the diagnosis of Langerhans cell histiocytosis with complementary tests showing no features of systemic involvement. Langerhans cell histiocytosis should be considered in the differential diagnosis of subacute neck masses with poor outcome in infants and physicians should consider performing a fine needle aspiration to establish the diagnosis...

Postmortem computed tomography (PMCT) of the brain has an important role in detection of subarachnoid hemorrhage (SAH), which has a high mortality rate. However, a phenomenon known as "pseudo-SAH," or high-attenuation areas along the cisterns mimicking SAH, may be seen on CT. The aim of this study was to evaluate the diagnostic accuracy of brain PMCT for SAH and to identify the characteristics of pseudo-SAH. Findings on PMCT (sulcal effacement, asymmetry, maximum thickness of SAH signs, presence of acute/subacute intraventricular/intraparenchymal hemorrhage) and clinical history (left ventricular assist device [LVAD] implantation, anticoagulation therapy/coagulation disorder, global ischemia) were compared between subjects with true SAH and those with pseudo-SAH...

Leber inherited optic neuropathy (LHON) is characterized by subacute bilateral loss of central vision due to dysfunction and loss of retinal ganglion cells (RGCs). Comprehensive visual electrophysiological investigations (including pattern reversal visual evoked potentials, pattern electroretinography and the photopic negative response) performed on 13 patients with acute and chronic LHON indicate early impairment of RGC cell body function and severe axonal dysfunction. Temporal, spatial and chromatic psychophysical tests performed on 7 patients with acute LHON and 4 patients with chronic LHON suggest severe involvement or loss of the midget, parasol and bistratified RGCs associated with all three principal visual pathways...

BACKGROUND: Postherpetic neuralgia (PHN) is a refractory condition that impairs the patient's quality of life (QoL), it develops secondary to herpes zoster infection. Therefore, it's important to prevent the transition of acute/subacute zoster-related pain to PHN. Despite of numerous studies, the optimal intervention that reduces PHN incidence is still unknown. OBJECTIVE: We evaluate the efficacy of short-term spinal cord stimulation (stSCS) in patients with refractory acute/subacute zoster-related pain...

Reports on neuroprotective effects of Insulin-like growth factor-1 (IGF-1) and Insulin-like growth factor binding protein-3 (IGFBP-3) in ischemic brain tissue are inconsistent. The aim of this study was to determine if plasma levels of IGF-1 and IGFBP-3 in acute stroke patients are indicative of 3 months functional outcome. Plasma levels were measured via chemiluminescence immunoassay in heparin blood samples of patients included in the EARLY trial (NCT00562588). Plasma samples were drawn on admission and 8 days post-stroke...

Behavioural disturbances are frequently found after aneurysmal subarachnoid haemorrhage (aSAH). Social cognition impairments have been suggested as a possible underlying mechanism for behavioural problems. Also, aSAH is likely to result in damage affecting frontal-subcortical circuits underlying social cognition. Therefore, we aimed to investigate social cognition after aSAH and its associations with behavioural problems (deficits in interpersonal behaviour, apathy, and impaired self-awareness) and focal as well as diffuse brain damage...
