BACKGROUND: The diagnostic gold standard for diagnosing chronic exertional compartment syndrome (CECS) is a dynamic intracompartmental pressure (ICP) measurement of the muscle. The potential role of a repeat ICP (re-ICP) measurement in patients with persistent lower leg symptoms after surgical decompression or with ongoing symptoms after an earlier normal ICP is unknown. PURPOSE: To study whether re-ICP measurements in patients with persistent CECS-like symptoms of the lower leg may contribute to the diagnosis of CECS after both surgical decompression and a previously normal ICP measurement...

Chronic exertional compartment syndrome that is refractory to conservative management should be treated with surgical fasciotomy. However, owing to the limitations of intracompartmental needle manometry in reaching a definite diagnosis, the appropriate timing for fasciotomy and on which compartment remain unclear. The authors report the case of a 22-year-old male military cadet who reported pain in his left calf when running or walking for long distances. The pain was located at the lateral aspect of the calf, from the mid-calf level to the ankle...

The transmembrane receptor guanylyl cyclase-C (GC-C), expressed on enterocytes along the intestine, is the molecular target of the GC-C agonist peptide linaclotide, an FDA-approved drug for treatment of adult patients with Irritable Bowel Syndrome with Constipation and Chronic Idiopathic Constipation. Polarized human colonic intestinal cells (T84, CaCo-2BBe) rat and human intestinal tissues were employed to examine cellular signaling and cystic fibrosis transmembrane conductance regulator (CFTR)-trafficking pathways activated by linaclotide using confocal microscopy, in vivo surface biotinylation, and protein kinase-II (PKG-II) activity assays...

Acute-on-chronic exertional compartment syndrome is a rare and severe progression of the likely common and more benign chronic exertional compartment syndrome. This is a report of one 17-year-old male on a pediatric inpatient service with bilateral anterior leg pain of unknown origin. Because of the nonspecific nature of pain, a high level of suspicion is required for timely diagnosis to avoid compartment ischemia and irreversible soft tissue and nerve damage. While high-energy orthopaedic trauma, orthopaedic surgery, or closed reduction and casting are common preceding events for compartment syndrome, this patient presented with acute-on-chronic exertional compartment syndrome...

Chronic myelomonocytic leukemia (CMML) and juvenile myelomonocytic leukemia (JMML) are characterized by monocytosis, myelodysplasia, and a characteristic hypersensitivity to GM-CSF. Currently, there are no available disease-modifying therapies for CMML, nor are there preclinical models that fully recapitulate the unique features of CMML. Through use of immunocompromised mice with transgenic expression of human GM-CSF, IL-3, and SCF in a NOD/SCID-IL2Rγ(null) background (NSGS mice), we demonstrate remarkable engraftment of CMML and JMML providing the first examples of serially transplantable and genetically accurate models of CMML...

INTRODUCTION: Muscle changes in patients with diabetes and lower leg pain due to chronic exertional compartment syndrome (CECS) were investigated before and after fasciotomy. METHODS: The tibialis anterior muscle was analyzed with histochemical and morphological techniques in 7 patients with diabetes and CECS before fasciotomy, and in 5 of them 1-year after fasciotomy. Non-diabetic patients with CECS and healthy subjects served as references. RESULTS: Before treatment, walking distance until occurrence of pain was limited (<0...

T lymphocyte homeostatic proliferation, driven by the engagement of T cell antigen receptor with self-peptide/major histocompatibility complexes, and signaling through the common γ-chain-containing cytokine receptors, is critical for the maintenance of the T cell compartment and is regulated by the Fas death receptor (Fas, CD95). In the absence of Fas, Fas-deficient lymphoproliferation spontaneous mutation (lpr) mice accumulate homeostatically expanded T cells. The functional consequences of sequential rounds of homeostatic expansion are not well defined...

REVIEW
Ralph Gaulke, Christian Krettek
Because of the complex fracture morphology and vulnerable soft tissue coverage, fractures of the tibial pilon are difficult to treat. Complications are more common than in bi- or trimalleolar fractures. The surgeon has to know about the special risks of these injuries to avoid complications. Early complications are soft tissue necrosis, persisting fragment dislocations after surgery, loss of reposition and deep wound infection. The surgeon has to be aware of early signs of compartment-syndrome and chronic regional pain syndrome (CRPS)...

BACKGROUND: Chronic lung allograft dysfunction in the form of bronchiolitis obliterans syndrome (BOS) is the main cause of death beyond 1-year post-lung transplantation. The disease-initiating triggers as well as the molecular changes leading to fibrotic alterations in the transplanted lung are largely unknown. The aim of this study was to identify potential early changes in the extracellular matrix (ECM) in different compartments of the transplanted lung prior to the development of BOS...

BACKGROUND: Chronic exertional compartment syndrome (CECS) is characterized by activity-induced pain, swelling, and decreased muscle function due to increased pressure and decreased circulation within a confined muscle compartment. Although well-known to occur in the leg, involvement of the hand has rarely been reported in the literature. METHODS: We present a 44 year old male with CECS involving bilateral thenar and hypothenar compartments. Symptoms were reproduced on exam by driving screws into wood with a screwdriver...

BACKGROUND: Foot compartment syndrome (FCS) has been reported to cause neuropathic pain, claw or hammer toes, and motor and sensory disturbances. The optimal treatment of FCS is controversial. The purpose of this study was to determine if foot fasciotomies improve patient outcomes in high-energy, combat-related lower extremity trauma. METHODS: Medical records of patients with documented FCS from May 2007 to January 2009 were retrospectively reviewed. Consecutive, matched control patients were identified based on similar hindfoot, mid-foot and/or forefoot injuries who did not undergo foot fasciotomy during the same period...

Impingement syndrome of the ankle is a clinical diagnosis caused posttraumatically by overuse due to repetitive mechanical loading or the presence of predisposing anatomical variants. Ankle impingement syndrome is characterized by chronic pain and limited range of movement caused by mechanical compression of bony or soft tissues within the joint compartments. Ankle impingement syndrome is classified according to the various anatomical locations around the tibiotalar joint as anterior, anterolateral, anteromedial, posterior or posteromedial...

Several novel therapeutics are poised to change the natural history of chronic lymphocytic leukaemia (CLL) and the increasing use of these therapies has highlighted limitations of traditional disease monitoring methods. Here we demonstrate that circulating tumour DNA (ctDNA) is readily detectable in patients with CLL. Importantly, ctDNA does not simply mirror the genomic information contained within circulating malignant lymphocytes but instead parallels changes across different disease compartments following treatment with novel therapies...

BACKGROUND: Chronic exertional compartment syndrome (CECS) is a recognized condition in the lower limb, with many reports in the literature. However, very few instances include CECS of the upper limb. This article presents the case of a collegiate softball pitcher presenting with CECS in her right forearm. To our knowledge, this is the first case report of a softball player with CECS, with only one similar incident in a major league baseball player. PURPOSE: The rarity of this condition normally places it low on the differential diagnosis...

PURPOSE: The forearm is prone to raised compartment pressure and it is the second most common site for compartment syndrome. The normal compartment pressure of the forearm should be known and serve as a benchmark for the diagnosis of acute and chronic compartment syndrome. This study was aimed to determine the normal compartment pressures of the forearm using a digital compartment pressure monitor. METHODS: This was a prospective hospital-based study of the uninjured forearm in 30 patients, who presented with closed unilateral forearm fracture at the accident and emergency department of a tertiary health care facility, between June 2012 and December 2013...

The term 'serotonin syndrome' describes a constellation of symptoms caused by serotonergic overstimulation. Its characteristic clinical presentation consists of encephalopathy, neuromuscular signs and autonomic hyperactivity. After removal of the offending agent, the clinical course is usually self-limited but can occasionally lead to severe symptoms. We report the case of a 68-year-old woman who presented emergently with encephalopathy. Home medications included paroxetine and dextroamphetamine/amphetamine...

M Tschopp, F Brunner
Running is one of the most popular sports worldwide, with running events attracting hundreds of thousands of runners of all age groups. Running is an effective way to improve health but is also associated with a high risk of injuries. Up to 50% of regular runners report having more than one injury each year. Some injuries are caused by an accident but most are caused by overuse. The most frequent diagnoses are patellofemoral pain syndrome, tibial stress syndrome (shin splint), Achilles tendinopathy, iliotibial band friction syndrome (runner's knee), plantar fasciitis and stress fractures of the metatarsals and tibia...

BACKGROUND: Magnetic resonance imaging (MRI) of thigh muscles is increasingly used to assess disease activity and damage extent in chronic myositis, but the validity of the findings is not clear. Here, the primary aim was to compare thigh MRI findings in patients having chronic myositis associated with anti-synthetase syndrome (ASS) and in matched healthy controls. METHODS: Cross-sectional analyses of thigh muscle MRI, muscular function and creatinine kinase (CK) were performed in 68 ASS patients (median disease duration 71 months) and 67 controls matched for age and gender...
