Skin Necrosis, Diffuse Urticaria, and Cellulitis Due to Presumed Loxosceles Spider Bite.

Wilderness Environ Med 2021 May 6. Epub 2021 May 6.

Department of Dermatology, Faculty of Medicine, Mersin University, Mersin, Turkey.

The clinical manifestations of a recluse spider bite range from local erythema to necrotic skin reactions; bites rarely lead to a systemic disease known as viscerocutaneous loxoscelism. A 29-y-old female patient was admitted to the emergency department with a wound, swelling, and pain on her left leg and a rash on her whole body as a result of a spider bite. On physical examination, a round, hard, black, irregularly shaped necrotic area was found in the bite zone on the lower posterior part of the left thigh, as were lesions in the form of erythematous papules around the area.

Simultaneous Cervical and Lumbar Spinal Cord Stimulation Induces Facilitation of Both Spinal and Corticospinal Circuitry in Humans.

Front Neurosci 2021 20;15:615103. Epub 2021 Apr 20.

Neuroscience and Mental Health Institute, University of Alberta, Edmonton, AB, Canada.

Coupling between cervical and lumbar spinal networks (cervico-lumbar coupling) is vital during human locomotion. Impaired cervico-lumbar coupling after neural injuries or diseases can be reengaged via simultaneous arm and leg cycling training. Sensorimotor circuitry including cervico-lumbar coupling may further be enhanced by non-invasive modulation of spinal circuity using transcutaneous spinal cord stimulation (tSCS). Read More

Effect of transcranial direct current stimulation on the psychomotor, cognitive, and motor performances of power athletes.

Sci Rep 2021 May 6;11(1):9731. Epub 2021 May 6.

Service de Psychiatrie de L'Adulte, Centre Hospitalier Universitaire de Besançon, 25030, Besançon Cedex, France.

In sports science, transcranial direct current stimulation (tDCS) has many unknown effects on neuromuscular, psychomotor and cognitive aspects. Particularly, its impact on power performances remains poorly investigated. Eighteen healthy young males, all trained in a jumping sport (parkour) performed three experimental sessions: anodal tDCS applied either on the left dorsolateral prefrontal cortex (dlPFC, cathode in supraorbital area) or on the primary motor cortex (M1, cathode on contralateral shoulder), and a placebo condition (SHAM), each applied for 20 min at 2 mA.

Does ischemic preconditioning really improve performance or it is just a placebo effect?

PLoS One 2021 3;16(5):e0250572. Epub 2021 May 3.

Physiology and Human Performance Research Group, Department of Physiology, Federal University of Juiz de Fora, Juiz de Fora, Minas Gerais, Brazil.

This study examined the effects of a simultaneous ischemic preconditioning (IPC) and SHAM intervention to reduce the placebo effect due to a priori expectation on the performance of knee extension resistance exercise. Nine moderately trained men were tested in three different occasions. Following the baseline tests, subjects performed a first set of leg extension tests after the IPC (3 X 5 min 50 mmHg above systolic blood pressure) on right thigh and the SHAM (same as IPC, but 20 mmHg) on left thigh.

Easy-to-use preload stress echocardiography by using combined dynamic postural stress can identify high-risk patients with heart failure with reduced ejection fraction.

ESC Heart Fail 2021 May 2. Epub 2021 May 2.

Division of Cardiovascular Medicine, Department of Internal Medicine, Kobe University Graduate School of Medicine, 7-5-2, Kusunoki-cho, Chuo-ku, Kobe, 650-0017, Japan.

Aims: Haemodynamic assessment during stress testing is not commonly performed in patients with heart failure with reduced ejection fraction (HFrEF) because of its invasiveness, lower feasibility, and safety concerns. This study aimed to assess the haemodynamic characteristics of patients with HFrEF in response to non-invasive preload stress during dynamic postural alterations achieved by combining both semi-sitting position and passive leg-lifting and to evaluate whether combined postural stress could be used for risk stratification in these patients.

Methods And Results: For this study, 101 patients with HFrEF and 35 age-matched and sex-matched healthy controls were prospectively recruited. Read More

The ins and outs of dynamic balance during 90-degree turns in people with a unilateral transtibial amputation.

J Biomech 2021 Apr 20;122:110438. Epub 2021 Apr 20.

School of Kinesiology, University of Michigan, Ann Arbor, MI 48109, USA. Electronic address:

The ability to maintain balance when turning is essential to functional and independent living. Due to the lack of neuromuscular ankle control on the prosthetic side in people with a transtibial amputation (TTA), turning is likely more challenging. The purpose of this study was to quantify how people with TTA maintain dynamic balance during 90-degree turns made with the prosthesis on the inside and outside of the turn compared to people without amputation.

Objective: An advantage of lateral lumbar interbody fusion (LLIF) surgery is the indirect decompression of the neural elements that occurs because of the resulting disc height restoration, spinal realignment, and ligamentotaxis. The degree to which indirect decompression occurs varies; no method exists for effectively predicting which patients will respond. In this study, the authors identify preoperative predictive factors of indirect decompression of the central canal. Read More

Diagnostics (Basel) 2021 Apr 22;11(5). Epub 2021 Apr 22.

Department of Nuclear Medicine, Institut Curie, 92210 Saint-Cloud, France.

Early detection of immune-related adverse events (irAEs) with immune checkpoint inhibitors (ICIs) is crucial, particularly when these are likely to mimic tumor progression, as well as sarcoid-like reactions. Here, we report the case of a 68-year woman, with a history of four primary cutaneous melanomas (thickest lesion with BRAF mutation removed from the left axilla 2 years before), who was diagnosed with BRAF V600E-mutant metastatic melanoma and treated by ICI targeting the PD-1 receptor. Follow-up whole-body positron emission tomography/computed tomography (PET/CT) using 18F-fluorodeoxyglucose ([18F]-FDG) was performed at 15 months, and FDG-avid subcutaneous nodules on her legs were detected.
