BACKGROUND: Work-related musculoskeletal disorders are defined as the disabling or painful injury to the muscles, nerves or tendons that are caused by work or aggravated by it. Some studies confirm the association between working in packaging units in various industries and the pain in the upper limb, but also there are controversies about the possible risk factors among different working populations. OBJECTIVE: The present study aims to define the potential ergonomic risk factors for musculoskeletal pain in the upper limb...

Leptospirosis is a systemic infection that causes, among others, acute kidney injury, acute liver disease, muscle pain, vasculitis, bleeding disorders, and reproductive loss. In an effort to reduce uterine inflammatory responses induced by Leptospira, we evaluated the anti-inflammation effects of emodin, thymol, and astragalin in a mouse model. Our results showed that treatment with emodin, thymol, and astragalin alleviated uterine inflammation induced by leptospira infection via suppression of pro-inflammatory cytokine expression and prevented tissue damage...

BACKGROUND: Rotator cuff tears are a common cause of shoulder pain and often necessitate operative repair. Muscle atrophy, fibrosis, and fatty infiltration can develop after rotator cuff tears, which may compromise surgical outcomes. This study investigated the regenerative potential of 2 human adipose-derived progenitor cell lineages in a murine model of massive rotator cuff tears. METHODS: Ninety immunodeficient mice were used (15 groups of 6 mice). Mice were assigned to 1 of 3 surgical procedures: sham, supraspinatus and infraspinatus tendon transection (TT), or TT and denervation via suprascapular nerve transection (TT + DN)...

Chronic pain in the Ehlers-Danlos syndromes (EDS) is common and may be severe. According to one study, nearly 90% of patients report some form of chronic pain. Pain, which is often one of the first symptoms to occur, may be widespread or localized to one region such as an arm or a leg. Studies on treatment modalities are few and insufficient to guide management. The following is a discussion of the evidence regarding the underlying mechanisms of pain in EDS. The causes of pain in this condition are multifactorial and include joint subluxations and dislocations, previous surgery, muscle weakness, proprioceptive disorders, and vertebral instability...

Whether upper-limb swelling is associated with axillary web syndrome (AWS) is unknown. We recruited unilateral breast cancer (BC) patients who were scheduled for surgical intervention and lymph node dissection. The pre-operative assessment and post-operative assessment 3-4 weeks after surgery evaluated the upper-limb circumferential measurements, segmental limb volume, pain scores, grasp, shoulder range of motion (ROM), shoulder muscle power and quality-of-life scores. In the control group, the peri-elbow volume and upper-arm volume were significantly higher post-operatively than pre-operatively...

BACKGROUND: Lateral epicondylitis is a common cause of pain and upper limb dysfunction. The use of counterforce straps for treatment of lateral epicondylitis is widespread. This kind of orthosis can be modified to have a greater effect on relieving pain by reducing tension on the origin of the extensor pronator muscles. OBJECTIVES: To determine the immediate effects of a newly designed orthosis on pain and grip strength in patients with lateral epicondylitis. MATERIALS AND METHODS: Twelve participants (six men and six women) were recruited (mean age = 41 ± 6...

Voltage-gated sodium channels are pore-forming transmembrane proteins that selectively allow sodium ions to flow across the plasma membrane according to the electro-chemical gradient thus mediating the rising phase of action potentials in excitable cells and playing key roles in physiological processes such as neurotransmission, skeletal muscle contraction, heart rhythm and pain sensation. Genetic variations in the nine human genes encoding these channels are known to cause a large range of diseases affecting the nervous and cardiac systems...

BACKGROUND: Aging is a contributing factor to rotator cuff tears. Dysfunction of the scapular muscles can be a potential cause of rotator cuff tears. Although aging can contribute to dysfunction of the scapular muscles, and subsequently result in rotator cuff tears, the effects of aging on scapular muscles are unclear. OBJECTIVE: To determine changes in sizes and electromyographic activities of the scapular muscles with age in asymptomatic subjects. DESIGN: Cross-sectional study PATIENTS: Fifty-four asymptomatic subjects without shoulder pain and dysfunction (18 males and 36 females) were recruited for this study...

INTRODUCTION: Tetanus is a severe and potentially fatal infection caused by the bacterium Clostridium tetani. Of all the cases described in literature, generalized tetanus is by far the most common presentation, but it may also present as neonatal tetanus, cephalic tetanus, and localized tetanus, the latter two being much rarer. In this case report, we present the rare form of this disease, i.e., localized tetanus in an adult male with a history of minimal trauma as well as a late, unusual mode of presentation...

Re-emergence of chikungunya virus, a mosquito-transmitted pathogen, is of serious public health concern. In the past 15 years, after decades of infrequent, sporadic outbreaks, the virus has caused major epidemic outbreaks in Africa, Asia, the Indian Ocean, and more recently the Caribbean and the Americas. Chikungunya virus is mainly transmitted by Aedes aegypti mosquitoes in tropical and subtropical regions, but the potential exists for further spread because of genetic adaptation of the virus to Aedes albopictus, a species that thrives in temperate regions...

: 97 Background: Myofascial pain syndrome (MPS) is a condition that involves skeletal muscles. It is caused by overload or disuse of muscles and is characterized by extreme tenderness in the muscles with taut bands. Treatment for MSP is different from that for cancer-related pain. Cancer patients have many factors that cause restriction of body movement and posture. Although cancer patients appear to demonstrate risk factors for MPS, its prevalence has not been reported in patients with incurable cancer...

We herein report the first case of a pancreatic fistula extending into the thigh caused by the rupture of an intraductal papillary mucinous neoplasm (IPMN) of the pancreas. An 80-year-old man was suspected to have necrotizing fasciitis because of right femoral pain. Computed tomography showed fluid retention from the pancreatic head to the right iliopsoas muscle and an IPMN at the pancreatic head. The findings of endoscopic retrograde pancreatography led to the suspicion of a minor leak and a pancreatic stent was placed...

Myocardial infarction (MI), a subset of acute coronary syndrome, is damage to the cardiac muscle as evidenced by elevated cardiac troponin levels in the setting of acute ischemia. Coronary artery disease is the leading cause of mortality in the United States. Chest pain is a common presentation in patients with MI; however, there are multiple noncardiac causes of chest pain, and the diagnosis cannot always be made based on initial presentation. The assessment of a possible MI includes evaluation of risk factors and presenting signs and symptoms, rapid electrocardiography, and serum cardiac troponin measurements...

REVIEW
Kyla Joubert, Jonathan A Laryea
Rectal prolapse is a debilitating condition with a complex etiology. Symptoms are most commonly prolapse of the rectum and pain with bowel movements or straining, with worsening fecal incontinence over time due to progressive stretching of the anal sphincters. Physical findings are fairly consistent from patient to patient-most notably diastasis of the levator ani muscles, deep pouch of Douglas, redundant sigmoid colon, a mobile mesorectum, and occasionally a solitary rectal ulcer. Evaluation includes a physical exam or imaging demonstrating the prolapse, and evaluating for other causes of pelvic floor dysfunction...

Anterior cutaneous nerve entrapment syndrome (ACNES) is a commonly underdiagnosed and undertreated chronic state of pain. This syndrome is characterized by the entrapment of the cutaneous branches of the lower thoracoabdominal intercostal nerves at the lateral border of the rectus abdominis muscle, which causes severe, often refractory, chronic pain. This narrative review aims to identify the possible therapeutic strategies for the management of the syndrome. Seventeen studies about ACNES therapy were reviewed; of them, 15 were case-control studies, case series, or case reports, and two were randomized controlled trials...

Shogo Watanabe, Shinichi Fukuhara, Takeshi Fujinaga, Hisao Oka
The summation of the muscle force caused by an increase in the firing rate is named a tetanic contraction (tetanus), and the minimum stimulation frequency necessary to evoke an unfused/fused tetanus is related to the contraction time (CT) and relaxation time (RT) of the twitch. In particular, the fusion index (FI) is a very useful indicator, and it is used to evaluate the change in the muscle fiber component ratio. However, the measurement of the FI is invasive, because most patients experience pain during the electrical stimulation for tetanus...
