Bites of tiger spiders belonging to Poecilotheria genus cause moderate to severe pain and long-lasting local or generalized muscle cramps in humans. Bites occur in regions of the spiders' natural habitat, India and Sri Lanka, but the popularity of these colorful tarantulas as pets leads to reports of envenomation cases worldwide. Treatment is predominantly symptomatic and often inadequate since there is almost no clinical or toxicology research data available, and physicians outside India or Sri Lanka typically have no experience in treating such cases...

BACKGROUND: Pathologies of the long head of biceps tendon (LHB) can cause anterior shoulder pain. Surgical treatment includes tenotomy and tenodesis (TD), however TD causes fewer cosmetic deformities and less cramping of the biceps muscle. To date, numerous techniques for TD have been described but the "gold standard" has not yet been established. OBJECTIVES: The purpose of this study is to evaluate the functional and cosmetic outcome following subpectoral biceps TD with an interference screw and a cortical-button (STLHB-IC) after 1 year...

REVIEW
Jason A Chou, Kamyar Kalantar-Zadeh
PURPOSE OF REVIEW: Volume management in hemodialysis patients is often challenging. Assessing volume status and deciding how much fluid to remove during hemodialysis, the so-called ultrafiltration rate (UFR), has remained a conundrum. RECENT FINDINGS: To date there is no objective assessment tool to determine the needed UFR during each hemodialysis session. Higher volume overload or higher UFR is associated with poor outcomes including worse mortality and unfavorable clinical outcomes...

Brody disease (BD, OMIM #601003) is an inherited skeletal muscle disease clinically characterized by exercise-induced impairment of muscle relaxation and stiffness due to the delay in the Ca(2+) re-uptake in the sarcoplasmic reticulum (SR)[1, 2]. The delayed muscle relaxation mainly affects legs, harms, hands and eyelids and usually improves after a few minutes rest [1-3]. Patients frequently report myalgia, painless or mildly painful cramps whereas recurrent rhabdomyolysis have been described in a few cases [2, 3]...

INTRODUCTION: Some clinicians advocate stretching to prevent muscle cramps. It is unknown if static or proprioceptive neuromuscular facilitation (PNF) stretching increases cramp threshold frequency (TFc ), a quantitative measure of cramp susceptibility. METHODS: Fifteen individuals completed this randomized, counterbalanced, cross-over study. We measured passive hallux ROM and then performed three minutes of either static stretching, PNF stretching (hold-relax-with agonist contraction), or no stretching...

BACKGROUND: In Guadeloupe (French West Indies), many marine envenomation cases by jellyfish are observed. Some of them might induce an Irukandji syndrome (IS). The aim of this study was to analyse the clinical features of IS from the envenomation cases in the two public hospitals in Guadeloupe, and to compare them to non-IS stings. METHODS: All jellyfish envenomation cases between the 1st of January 2010 and the 1st of September 2016, from the emergencies data-base, have been extracted...

Triathletes need to effectively fuel during training and racing to maximize their potential for success. While most research on fueling has focused on elite male triathletes, triathlon participation encompasses a broader demographic of racers ranging from those with aspirations of winning to those whose goals are completion. Carbohydrate is the primary macronutrient for fueling endurance activities. Athletes can usually tolerate 60 to 90 mg·h in the form of multiple different carbohydrate sources. Athletes should drink as thirst dictates and consider sodium replacement of sweat loss especially in individuals with a history of exercise-associated muscle cramps...

AIM: Acute gastric or intestinal spasm-like pain is a common symptom in digestive diseases. Hyoscine butylbromide (HBB), an anticholinergic agent, relieves the pain of stomach and bowel cramps by inhibiting smooth muscle contractility. The aim was to compare the efficacy and safety of parenteral HBB versus anisodamine, for acute gastric or intestinal spasm-like pain. METHODS: In this randomized, positive-controlled, double-blind, parallel-group, multi-center non-inferiority trial, 299 Chinese patients were randomly assigned to HBB or anisodamine in a 1:1 ratio...

A self-rating scale was developed to permit patient-reported, remote assessment of Parkinson's disease symptom severity. The goal was to create a continuous outcome measure that does not require a clinical exam, does not fluctuate in response to dopaminergic medications, takes only a few minutes to complete, allows for stratification by symptom(s), and captures both motor and non-motor Parkinson's disease symptoms, major contributors to quality of life. The Patient Reported Outcomes in Parkinson's Disease (PRO-PD) is the cumulative score of 32 slider bars, each evaluating a common Parkinson's disease symptom...

The analgesic properties of myrrh (Commiphora myrrha) have been known since ancient times and depend on the presence of bioactive sesquiterpenes with furanodiene skeletons. MyrLiq is a C. myrrha extract with a standardized content of curzerene, furanoeudesma-1,3-diene, and lindestrene (12.31 ± 0.05 g kg(-1), 18.84 ± 0.02 g kg(-1), and 6.23 ± 0.01 g kg(-1), resp.) and a high total furanodiene content (40.86 ± 0.78 g kg(-1)). A balanced sample of 95 female and 89 male volunteers (with ages ranging from 18 to older than 60 years) exhibiting different pain pathologies, including headache, fever-dependent pain, joint pain, muscle aches, lower back pain, and menstrual cramps, was divided into two groups...

INTRODUCTION: Patients with Ehlers Danlos Syndrome are known to have genetically impaired connective tissue and skeletal muscle symptoms in form of pain, fatigue and cramps, however earlier studies have not been able to link these symptoms to morphological muscle changes. METHODS: We obtained skeletal muscle biopsies in patients with classic EDS (cEDS, n=5 (Denmark)+ 8 (The Netherlands)) and vascular EDS (vEDS, n=3) and analyzed muscle fiber morphology and content (Western blotting and muscle fiber type/area distributions) and muscle mRNA expression and protein synthesis rate (RT-PCR and stable isotope technique)...

PURPOSE: Previous data indicate that a strong sensory input from orally administered TRPV1 and TRPA1 activators alleviates muscle cramps in foot muscles by reducing the α-motor neuron hyperexcitability. We investigated if TRP activators increase the cramp threshold frequency of the medial gastrocnemius. METHODS: We randomly assigned 22 healthy male participants to an intervention (IG) and a control group (CG). While participants of the IG ingested a mixture of TRPV1 and TRPA1 activators, the CG received a placebo...

BACKGROUND: Mast cells are present in the airways of patients who have severe asthma despite glucocorticoid treatment; these cells are associated with disease characteristics including poor quality of life and inadequate asthma control. Stem cell factor and its receptor, KIT, are central to mast-cell homeostasis. We conducted a proof-of-principle trial to evaluate the effect of imatinib, a KIT inhibitor, on airway hyperresponsiveness, a physiological marker of severe asthma, as well as on airway mast-cell numbers and activation in patients with severe asthma...
