Platelet-rich Plasma for Skin Rejuvenation and Treatment of Actinic Elastosis in the Lower Eyelid Area.

Cureus 2018 Jul 18;10(7):e2999. Epub 2018 Jul 18.

Plastic Surgery, Waldkrankenhaus Bonn, Bonn, DEU.

Background Treatment of the lower eyelid region to rejuvenate the skin or treat actinic elastosis often proves difficult. Established treatment options, such as hyaluronic acid injections, botulinum toxin injections, microneedling, skin resurfacing (microdermabrasion, chemical peel (exfoliation), laser treatment), as well as blepharoplasties and autologous fat transfers, can be associated with significant risks and increased patient burden. Furthermore, they may not be effective for treating the signs of skin aging or actinic elastosis, including dark rings under the eyes, a lack of volume and cutis laxa. Read More

Real-Time Monitoring of a Botulinum Neurotoxin Using All-Carbon Nanotube-Based Field-Effect Transistor Devices.

Sensors (Basel) 2018 Dec 3;18(12). Epub 2018 Dec 3.

Department of Chemistry, KAIST, 291 Daehak-ro, Yuseong-gu, Daejeon 34141, Korea.

The possibility of exposure to botulinum neurotoxin (BoNT), a powerful and potential bioterrorism agent, is considered to be ever increasing. The current gold-standard assay, live-mouse lethality, exhibits high sensitivity but has limitations including long assay times, whereas other assays evince rapidity but lack factors such as real-time monitoring or portability. In this study, we aimed to devise a novel detection system that could detect BoNT at below-nanomolar concentrations in the form of a stretchable biosensor. Read More

Release of astroglial vimentin by extracellular vesicles: Modulation of binding and internalization of C3 transferase in astrocytes and neurons.

Glia 2018 Nov 28. Epub 2018 Nov 28.

Institute of Integrative Neuroanatomy, Charité - Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Berlin, Germany.

Clostridium botulinum C3 transferase (C3bot) ADP-ribosylates rho proteins to change cellular functions in a variety of cell types including astrocytes and neurons. The intermediate filament protein vimentin as well as transmembrane integrins are involved in internalization of C3bot into cells. The exact contribution, however, of these proteins to binding of C3bot to the cell surface and subsequent cellular uptake remains to be unraveled. Read More

The control of neuronal calcium homeostasis by snap-25 and its impact on neurotransmitter release.

Neuroscience 2018 Nov 23. Epub 2018 Nov 23.

Humanitas University, Via Rita Levi Montalcini, 4, 20090 Pieve Emanuele, Milano, Italy; IRCCS Humanitas, via Manzoni 56, 20089 Rozzano, Italy. Electronic address:

The process of neurotransmitter release is central to the control of cell-to-cell communication in brain. SNAP-25 is a component of the SNARE complex, which, together with syntaxin-1 and synaptobrevin, mediates synaptic vesicle fusion with the plasma membrane. The genetic ablation of the protein or its proteolytic cleavage by botulinum neurotoxins results in a complete block of synaptic transmission. Read More

Department of Oral and Maxillofacial Surgery, University Hospital of Besançon, boulevard Fleming, 25030 Besançon cedex, France.

Introduction: Hyperactivity of the lateral pterygoid muscle (LPM) is one of the presumed mechanisms of the onset of temporomandibular disorders (TMD) and explains why intramuscular injection of botulinum toxin (BT) may be indicated for treatment. Intramuscular injection without guidance is difficult because of its deep location. The objectives of this study were to determine the feasibility of MR-guided navigation for BT injection in the LPM in TMD and to report about our first results. Read More

Botulinum neurotoxin (BoNT) intoxication can lead to the disease botulism, characterized by flaccid muscle paralysis that can cause respiratory failure and death. Due to the significant morbidity and mortality costs associated with BoNTs high toxicity, developing highly sensitive, rapid, and field-deployable assays are critically important to protect the nation's food supply against either accidental or intentional contamination. We report here that the B-cell based biosensor assay CANARY (Cellular Analysis and Notification of Antigen Risks and Yields) Zephyr detects BoNT/A holotoxin at limits of detection (LOD) of 10.

Neurostimulation-Guided Anal Intrasphincteric Botulinum Toxin Injection in Children with Hirschsprung's Disease.

J Pediatr Gastroenterol Nutr 2018 Nov 15. Epub 2018 Nov 15.

Pediatric Surgery Department, Hôpital La Timone-Enfants, Marseille, France.

Objectives: In Hirschsprung's disease (HD), despite successful surgical treatment, 50% of children experience long-term functional gastrointestinal problems, particularly chronic functional obstructive symptoms. We report our experience regarding clinical effects of neurostimulation-guided anal intrasphincteric botulinum toxin (BT) injections on postoperative obstructive symptoms attributed to a non-relaxing anal sphincter complex in HD patients.

Methods: In this monocenter cohort study, 15 HD patients with postoperative functional intestinal obstructive symptoms received neurostimulation-guided anal intrasphincteric BT injections. Read More

Bulbar Muscle Weakness in the Setting of Therapeutic Botulinum Injections.

Clin Pract Cases Emerg Med 2018 Nov 28;2(4):330-333. Epub 2018 Sep 28.

University of California, Los Angeles, Department of Emergency Medicine, Los Angeles, California.

We present a case of new-onset bulbar muscle weakness in the setting of therapeutic botulinum injections for spasticity in a teenaged patient with cerebral palsy. Through a careful history, a systemic effect of the local injections was suspected, and the patient's symptoms improved with a decrease in the dosing of the botulinum injections. Read More
