REVIEW
Jose Manuel Carbajo, Francisco Maraver
In Health Resort Medicine, both balneotherapy and thalassotherapy, salt waters and their peloids, or mud products are mainly used to treat rheumatic and skin disorders. These therapeutic agents act jointly via numerous mechanical, thermal, and chemical mechanisms. In this review, we examine a new mechanism of action specific to saline waters. When topically administered, this water rich in sodium and chloride penetrates the skin where it is able to modify cellular osmotic pressure and stimulate nerve receptors in the skin via cell membrane ion channels known as "Piezo" proteins...

There are few data available that describe the current anaesthetic management of children. We have analysed anaesthetic practice and peri-operative complications for children in Denmark aged less than two years. We conducted a population-based observational cohort study using the Danish Anaesthesia Database to identify children who received anaesthesia in hospital from 1 January 2005 until 31 December 2015. Data were combined with that from the Danish National Patient Registry and the Danish Civil Registration System...

First responders and health care providers must prepare to provide care for patients poisoned by acetylcholinesterase (AchE) inhibitor chemical warfare agents or pesticides. However, pre-deployed medical countermeasures (MCMs) may not be sufficient due to production and delivery interruption, rapid depletion of contents during a response, expiration of MCM components, or lack of local availability of approved MCMs. To augment supplies of community-based and forward-deployed nerve agent countermeasures, the American College of Medical Toxicology (ACMT) supports several strategies: (1) The use of expired atropine, diazepam, and pralidoxime auto-injectors and vials if non-expired drugs are unavailable; and (2) Investigation, development, and identification of alternative countermeasures-commonly stocked drugs that are not approved for nerve agent poisoning but are in the same therapeutic class as approved drugs...

In daily clinical practice, there is a growing number of patients receiving new biological agents used in the treatment of malignancies. Ipilimumab is a fully humanized monoclonal antibody approved for patients with melanoma. It acts as an immune checkpoint inhibitor, binding and blocking cytotoxic T-lymphocyte antigen-4 in order to increase the antitumor immune response. There are several reports of autoimmune responses after its use. A 74-year-old man developed a mild rash and pruritus a few hours after the second infusion of ipilimumab and 24 h after the third dose of ipilimumab, he presented with shortness of breath, proximal limb muscle weakness, and diplopia...

Magnetic resonance imaging (MRI) combined with contrast agents is believed to be useful for stem cell tracking in vivo, and the aim of this research was to investigate the biosafety and neural induction of SD rat-originated adipose derived stem cells (ADSCs) using cationic superparamagnetic iron oxide (SPIO) nanoparticle which was synthesized by the improved polyol method, in order to allow visualization using in vitro MRI. The scan protocols were performed with T2-mapping sequence; meanwhile, the ultrastructure of labeled cells was observed by transmission electron microscopy (TEM) while the iron content was measured by inductively coupled plasma-atomic emission spectrometry (ICP-AES)...

Nerve agents are organophosphorus chemical warfare agents that exert their action through the irreversible inhibition of acetylcholinesterase, with a consequent overstimulation of cholinergic transmission followed by its shutdown. Beyond warfare, they have notoriously been employed in acts of terrorism as well as high profile assassinations. After a brief historical introduction on the development and deployment of nerve agents, this review provides a survey of their chemistry, the way they affect cholinergic transmission, the available treatment options, and the current directions for their improvement...

OBJECTIVE: The selection of local anesthetic in dental practice is essential to the patient's comfort and the success of the treatment. Many patients prefer anesthesia even for short treatments. Articaine is a local anesthetic commonly used for dental practice. The duration of the effect of articaine on the nerve fibers is not yet precisely reported. This study was aimed to evaluate the clinical efficacy of 4% articaine with and without epinephrine in treatment of occlusal caries. MATERIALS AND METHODS: Thirty healthy patients were included in this randomized double-blind study...

Adriamycin is a potent anthracycline-type antitumor agent, but it also exerts potentially serious side effects due to its cardiotoxic and neurotoxic propensity. Multiple impairments in sensory nerve functions have been recently reported in various rat models. The present experiments were initiated in an attempt to reveal adriamycin-induced changes in sensory effector functions of chemosensitive meningeal afferents. Meningeal blood flow was measured with laser Doppler flowmetry in the parietal dura mater of adult male Wistar rats...

CHARGE syndrome is linked to autosomal dominant mutations in the CHD7 gene and results in a number of physiological and structural abnormalities, including heart defects, hearing and vision loss and gastrointestinal (GI) problems. Of these challenges, GI problems have a profound impact throughout an individual's life, resulting in increased morbidity and mortality. A homologue of CHD7 has been identified in the zebrafish, the loss of which recapitulates many of the features of the human disease. Using a morpholino chd7 knockdown model complemented by a chd7 null mutant zebrafish line, we examined GI structure, innervation, and motility in larval zebrafish...

Several chemotherapeutic agents used for cancer treatment induce dose-limiting peripheral neuropathy that compromises patients' quality of life and limits cancer treatment. Recently, mitochondrial dysfunction has been shown to be involved in the mechanism of chemotherapy-induced peripheral neuropathy. SS-20 is a mitochondria-targeted peptide that promotes mitochondrial respiration and restores mitochondrial bioenergetics. In the present study, we examined the protective effect of SS-20 against the development of chemotherapy-induced peripheral neuropathy utilizing a murine model of peripheral neuropathy induced by oxaliplatin, a first-line chemotherapy agent for colon cancer...

BACKGROUND AND OBJECTIVES: This randomized trial compared ultrasound (US)-guided interscalene block (ISB) and small-volume supraclavicular block (SCB) for arthroscopic shoulder surgery. We hypothesized that SCB would provide equivalent analgesia to ISB 30 minutes after surgery without the risk of hemidiaphragmatic paralysis (HDP). METHODS: All patients received an US-guided intermediate cervical plexus block. In the ISB group, US-guided ISB was performed with 20 mL of levobupivacaine 0...

Video-assisted thoracoscopic surgery (VATS) is a minimally invasive technique that allows a faster recovery after thoracic surgery. Although enhanced recovery after surgery (ERAS) principles seem reasonably applicable to thoracic surgery, there is little literature on the application of such a strategy in this context. In regard to pain management, ERAS pathways promote the adoption of a multimodal strategy, tailored to the patients. This approach is based on combining systemic and loco-regional analgesia to favour opioid-sparing strategies...

As the rate of total joint arthroplasty increases with the aging population of the United States, new focus on decreasing opioid use through the development of multimodal pain regimens (MPRs) is becoming an important area of research. MPRs use different agents and modes of delivery in order to synergistically address pain at many levels of the pain pathway. MPRs include a combination of acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), gabapentinoids, opioids (short- and long-acting), spinal/epidural analgesia, regional nerve blocks, and local anesthetics...

Collagen XIII occurs as both a transmembrane-bound and a shed extracellular protein, and is able to regulate the formation and function of neuromuscular synapses. Its absence results in myasthenia, i.e. pre-and postsynaptic defects at the neuromuscular junction (NMJ), leading to destabilization of the motor nerves, muscle regeneration and atrophy. Mutations in COL13A1 have recently been found to cause congenital myasthenic syndrome (CMS), characterized by fatigue and chronic muscle weakness, which may be lethal...

BACKGROUND: A dose-limiting side effect of chemotherapeutic agents such as vincristine (VCR) is neuropathic pain, which is poorly managed at present. Chemokine-mediated immune cell/neuron communication in preclinical VCR-induced pain forms an intriguing basis for the development of analgesics. In a murine VCR model, CX3 CR1 receptor-mediated signalling in monocytes/macrophages in the sciatic nerve orchestrates the development of mechanical hypersensitivity (allodynia). CX3 CR1 -deficient mice however still develop allodynia, albeit delayed; thus, additional underlying mechanisms emerge as VCR accumulates...

BACKGROUND: The concept of the effect-site concentration of anesthetic agents is important. The effect compartment model can be explained using the concepts of effect-site concentration and effect-site equilibration rate constant ( k e0 ). This study confirms that the time-to-peak effect ( tpe ) can be measured easily in clinical practice by applying a priming dose and train-of-four (TOF) during general anesthesia induction, and k e0 can be calculated from the tpe of the four muscle relaxants that are commonly used in general anesthesia...
