RUNX2 as a novel biomarker for early identification of patients progressing to advanced-stage mycosis fungoides.

Introduction: The majority of patients with mycosis fungoides (MF) have an indolent disease course, but a substantial fraction (20-30%) of patients progress to advanced stages - usually with a grave prognosis. Early differentiation between indolent and aggressive types of MF is important for the choice of treatment regimen and monitoring of the individual patient. Good biomarkers are therefore desired.

Multicentre investigation on the effect of decompressive surgery on Balance and physical ActiviTy Levels amongst patients with lumbar Spinal stenosis (B-ATLAS): protocol for a prospective cohort study.

Introduction: Patients with lumbar spinal stenosis may have poor balance, decreased physical function and problems maintaining physical activity levels due to radiculopathy. Decompressive surgery is often indicated if conservative management fails to achieve a satisfactory clinical outcome. While surgical management has proven effective at treating radiculopathy, and patients report increased physical function postoperatively, objective measures of postural control and physical activity remain sparse.

High-intensity resistance training improves quality of life, muscle endurance and strength in patients with myositis: a randomised controlled trial.

Myositis is associated with reduced quality of life, which is accompanied by significant impairments in muscle endurance and strength, altogether representing cardinal traits in patients with myositis. This randomised controlled trial aimed to investigate the effect of high-intensity resistance training on quality of life in patients with myositis. Thirty-two patients with established, stable myositis were randomised to 16 weeks of high-intensity resistance training (intervention group) or 16 weeks of usual care (control group).

Effects of sporadic inclusion body myositis on skeletal muscle fibre type specific morphology and markers of regeneration and inflammation.

Sporadic inclusion body myositis (sIBM) is a subgroup of idiopathic inflammatory myopathies characterised by progressive muscle weakness and skeletal muscle inflammation. Quantitative data on the myofibre morphology in sIBM remains scarce. Further, no previous study has examined fibre type association of satellite cells (SC), myonuclei number, macrophages, capillaries, and myonuclear domain (MD) in sIBM patients.

Work Disability and Return to Work After Treatment for Acute Lymphoblastic Leukemia: A Danish Nationwide Cohort Study.

Purpose: Most adult patients diagnosed with acute lymphoblastic leukemia (ALL) are below retirement age. The overall survival of patients with ALL has improved with implementation of high intensity pediatric-inspired treatment protocols. However, this treatment comes with a risk of long-term complications, which could affect the ability to work.

Staphylococcus aureus induces drug resistance in cancer T cells in Sézary syndrome.

Patients with Sézary syndrome (SS), a leukemic variant of cutaneous T-cell lymphoma (CTCL), are prone to Staphylococcus aureus infections and have a poor prognosis due to treatment resistance. Here, we report that S aureus and staphylococcal enterotoxins (SE) induce drug resistance in malignant T cells against therapeutics commonly used in CTCL. Supernatant from patient-derived, SE-producing S aureus and recombinant SE significantly inhibit cell death induced by histone deacetylase (HDAC) inhibitor romidepsin in primary malignant T cells from patients with SS.

Effect of early initiation of steroid-sparing drugs in patients with bullous pemphigoid.

Introduction: Bullous pemphigoid (BP) can be treated using systemic and topical glucocorticoids and/or other immunomodulatory agents. However, the long-term use of systemic glucocorticoids causes severe adverse side effects. This study was aimed at investigating whether the early initiation of corticosteroid-sparing therapy (CST) in BP patients results in better outcomes than late or no CST.

S2k guidelines on the management of paraneoplastic pemphigus/paraneoplastic autoimmune multiorgan syndrome initiated by the European Academy of Dermatology and Venereology (EADV).

Background: Paraneoplastic pemphigus (PNP), also called paraneoplastic autoimmune multiorgan syndrome (PAMS), is a rare autoimmune disease with mucocutaneous and multi-organ involvement. PNP/PAMS is typically associated with lymphoproliferative or haematological malignancies, and less frequently with solid malignancies. The mortality rate of PNP/PAMS is elevated owing to the increased risk of severe infections and disease-associated complications, such as bronchiolitis obliterans.

[Bullous skin diseases].

This review finds that topical corticosteroids and systemic corticosteroids are the mainstays of initial treatment for bullous pemphigoid and pemphigus diseases. Additional immunomodulatory therapies such as methotrexate, azathioprine and mycophenolatmofetil should be added early during treatment to minimize the adverse effects of chronic corticosteroid therapy and to augment improvement in the disease. Rituximab is a first-line immunomodulatory treatment for moderate to severe pemphigus disease.

Malignant T cells induce skin barrier defects through cytokine-mediated JAK/STAT signaling in cutaneous T-cell lymphoma.

Cutaneous T-cell lymphoma (CTCL) is a devastating lymphoid malignancy characterized by the accumulation of malignant T cells in the dermis and epidermis. Skin lesions cause serious symptoms that hamper quality of life and are entry sites for bacterial infection, a major cause of morbidity and mortality in advanced diseases. The mechanism driving the pathological processes that compromise the skin barrier remains unknown.

Lack of muscle stem cell proliferation and myocellular hypertrophy in sIBM patients following blood-flow restricted resistance training.

Sporadic inclusion body myositis (sIBM) is characterised by skeletal muscle inflammation, progressive muscle loss and weakness, which is largely refractory to immunosuppressive treatment. Low-load blood-flow restricted (BFR) training has been shown to evoke gains in myofibre cross sectional area (mCSA) in healthy adults. This could partially be due to the activation and integration of muscle satellite cells (SC) resulting in myonuclei addition.

Acral Necrosis in a COVID-19-Infected Man Treated with Botulinum Toxin Type A.

COVID-19 has been associated with acral ischemia and digital necrosis. Standard treatment of acral ischemia and digital or acral necrosis includes ongoing therapy with vasodilators and anticoagulants. However, these treatments are not always efficient to avoid the progression of necroses, which in the worst case can lead to amputation.

Pyoderma Gangrenosum and Interleukin Inhibitors: A Semi-Systematic Review.

Background: Pyoderma gangrenosum (PG) is a rare ulcerating skin disease associated with multiple comorbidities and increased mortality. In recent decades, newer biologics such as interleukin inhibitors have been used to treat PG; however, the literature is scarce, consisting predominantly of case reports and caseseries. The aim of our review was to evaluate the effectiveness and safety of interleukin inhibitors for the treatment of PG in adults.

[Spinefractures - diagnosis and treatment].

Acute onset back pain is a common reason for referral to primary health care or emergency departments. In this review, the different spine fracture types are highlighted, and a treatment algorithm is proposed. CT is the modality of choice when a spine fracture is suspected.

[Pyoderma gangrenosum].

Pyoderma gangrenosum is a diagnostic and therapeutic challenge. A misdiagnosis or delayed diagnosis can lead to increased morbidity and death. A fast workup and initiation of treatment is essential.

[Diagnostic approach of bullous skin disease].

Bullous skin diseases are characterised by a large group of diseases, where the essential clinical feature is fluid-filled skin lesions. Physicians in many different specialities can meet patients with bullous skin diseases, which include a wide range of skin diseases from mild cases to very severe and life-threating diseases. The aim of this review is to provide systematically approach of how make the accurate diagnosis, using important and basic elements of history taking, clinical and paraclinical examination.

Evaluation of Treatment With Respiratory Gene Technology and Serum in a Group of Standard Bred Racehorses With Cytological Evidence of Mild Equine Asthma.

Alternative treatment options to glucocorticoids for equine asthma is desirable due to withdrawal time. The objective was to evaluate if serum and Respiratory Gene Technology (RGT), a commercial kit to produce autologous conditioned serum, was effective in reducing bronchoalveolar lavage (BAL) neutrophils and mast cells in racehorses with cytological evidence of mild equine asthma . Thirty-six Standardbred trotters in active training were enrolled in this randomized clinical trial; a healthy control group (n=11), a RGT group (n=12) and a serum group (n=13).

Comorbidities, mortality and survival in patients with pyoderma gangrenosum: a Danish nationwide registry-nested case-control study.

Background: Pyoderma gangrenosum (PG) is an ulcerative skin disease associated with comorbidities and increased mortality; however, the literature on this topic is scarce.

Objectives: To investigate the mortality, prevalence and risk of comorbidities in patients with PG.

Methods: This nationwide registry nested case-control study included all inpatients and outpatients diagnosed with PG in tertiary dermatology centres in Denmark between 1 January 1994 and 31 December 2016.

Pyoderma Gangrenosum: A Retrospective Study of Clinical Charac-teristics, Comorbidities, Response to Treatment and Mortality Related to Prednisone Dose.

Pyoderma gangrenosum is an uncommon ulcerative neutrophilic dermatosis. Clinical presentation, location and associated diseases are diverse. Treatment of pyoderma gangrenosum includes treating the underlying comorbidity supplemented with topical and/or systemic agents.

Updated S2K guidelines on the management of pemphigus vulgaris and foliaceus initiated by the european academy of dermatology and venereology (EADV).

Background: Pemphigus encompasses a group of life-threatening autoimmune bullous diseases characterized by blisters and erosions of the mucous membranes and skin. Before the era of immunosuppressive treatment, pemphigus was almost always fatal. Due to its rarity, only few randomized controlled therapeutic trials are available.

Skeletal Muscle Microvascular Changes in Response to Short-Term Blood Flow Restricted Training-Exercise-Induced Adaptations and Signs of Perivascular Stress.

Previous reports suggest that low-load muscle exercise performed under blood flow restriction (BFR) may lead to endurance adaptations. However, only few and conflicting results exist on the magnitude and timing of microvascular adaptations, overall indicating a lack of angiogenesis with BFR training. The present study, therefore, aimed to examine the effect of short-term high-frequency BFR training on human skeletal muscle vascularization.

The immune system in sporadic inclusion body myositis patients is not compromised by blood-flow restricted exercise training.

Background: Sporadic inclusion body myositis (sIBM) is clinically characterised by progressive proximal and distal muscle weakness and impaired physical function while skeletal muscle tissue displays abnormal cellular infiltration of T cells, macrophages, and dendritic cells. Only limited knowledge exists about the effects of low-load blood flow restriction exercise in sIBM patients, and its effect on the immunological responses at the myocellular level remains unknown. The present study is the first to investigate the longitudinal effects of low-load blood flow restriction exercise on innate and adaptive immune markers in skeletal muscle from sIBM patients.

Pemphigus Vulgaris: Short Time to Relapse in Patients Treated in a Danish Tertiary Referral Center.

Pemphigus vulgaris is an autoimmune skin disorder with development of blisters in the skin and mucosa, and it can be a life-threatening disease if not treated. Corticosteroids have been a cornerstone for treating PV, but because of side effects the treatment is combined with other conventional immune modulating drugs and rituximab. The Danish treatment protocol for pemphigus vulgaris is similar to the other Scandinavian countries, and therefore this study is of importance for clinicians in the Scandinavian countries as well as other European countries.
