Targeting non-canonical nuclear factor-κB signalling attenuates neovascularization in a novel 3D model of rheumatoid arthritis synovial angiogenesis.

Objective: Angiogenesis is crucial in RA disease progression. Lymphotoxin β receptor (LTβR)-induced activation of the non-canonical nuclear factor-κB (NF-κB) pathway via NF-κB-inducing kinase (NIK) has been implicated in this process. Consequently, inhibition of this pathway may hold therapeutic potential in RA.

A new technique to simplify the minimally invasive parathyroidectomy: Ultrasound-assisted guided wire localization for solitary parathyroid adenomas.

Objective: To investigate the benefits of ultrasound-assisted guided wire localization in MIP for selected cases.

Methods: In this prospective, nonrandomised study, we included 36 patients with solitary parathyroid adenomas diagnosed preoperatively by 99m Tc sesta MIBI scintigraphy and/or neck ultrasonography. An ultrasound-guided wire was placed in the solitary parathyroid adenoma preoperatively.

L-carnitine has a protective effect on the colonic mucosa during abdominopelvic radiotherapy in rats.

Purpose:: To evaluate histopathologically the radioprotective effect of L-carnitine on the colonic mucosa in rats undergoing abdominopelvic irradiation.

Methods:: Thirty-two rats were randomly assigned to four experimental groups: intraperitoneal administration of normal saline (group 1) or L-carnitine (300 mL/kg; group 2), followed in groups 3 and 4, respectively, by one dose of abdominopelvic radiation (20 Gy) 30 min later. Rats were sacrificed 5 days after radiation, and their descending colons were resected for histopathological evaluation of the presence and severity of damage.

EGFR mutation testing using archival-stained smears in non-small cell lung carcinoma.

Objective: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have shown benefits regarding progression-free and overall survival in patients whose tumours show EGFR mutations. Most patients' lung cancer is metastatic when detected. Small tissue samples and cytological materials are widely used in diagnosis.

Vitamin-D measurement in patients with adolescent idiopathic scoliosis.

Our retrospective study compared vitamin-D levels in 229 patients with adolescent idiopathic scoliosis (AIS) and 389 age-matched controls, and evaluated the correlation between vitamin-D levels and sex, Cobb's angle, and serum levels of calcium (Ca), phosphorus, and alkaline phosphatase in the AIS group. Vitamin-D levels were lower in the AIS group, with no sex-specific effects, indicative of a possible vitamin-D resistance in AIS. Vitamin-D levels correlated positively with Ca levels and negatively with Cobb's angle, indicative of a possible role of vitamin D in the etiopathogenesis of AIS.

The effect of amifostine on bacterial translocation after radiation ınduced acute enteritis.

Methods: Thirty-two female Wistar albino rats were divided into four groups: Group-1 (n=8): only normal saline was administered intraperitoneally. Group-2 (n=8): first serum saline was administered intraperitoneally and 30 minutes later 20 Gy radiation was applied to abdominopelvic region.

Discovery of Innovative Therapies for Rare Immune-Mediated Inflammatory Diseases via Off-Label Prescription of Biologics: The Case of IL-6 Receptor Blockade in Castleman's Disease.

Biologics have revolutionized the field of clinical immunology and proven to be both effective and safe in common immune-mediated inflammatory diseases (IMIDs) such as rheumatoid arthritis, inflammatory bowel diseases, and various hematological disorders. However, in patients with rare, severe IMIDs failing on standard therapies, it is virtually impossible to conduct randomized controlled trials. Therefore, biologics are usually prescribed off-label in these often severely ill patients.

An investigation of the relationship of drooling with nutrition and head control in individuals with quadriparetic cerebral palsy.

[Purpose] The aim of the present study was to investigate the relationship of drooling, nutrition, and head control in individuals with quadriparetic cerebral palsy. [Subjects and Methods] Fifty-six individuals between the ages 2 and 15 diagnosed with spastic quadriparetic cerebral palsy and their families/caretakers were included in the study. Drooling severity and frequency of individuals was evaluated by using the scale developed by Thomas-Stonell and Greenberg (Drooling Severity and Frequency Scale).

Targeting of proangiogenic signalling pathways in chronic inflammation.

Angiogenesis is de novo capillary outgrowth from pre-existing blood vessels. This process not only is crucial for normal development, but also has an important role in supplying oxygen and nutrients to inflamed tissues, as well as in facilitating the migration of inflammatory cells to the synovium in rheumatoid arthritis, spondyloarthritis and other systemic autoimmune diseases. Neovascularization is dependent on the balance of proangiogenic and antiangiogenic mediators, including growth factors, cytokines, chemokines, cell adhesion molecules and matrix metalloproteinases.

Correcting the Alar Base Retraction in Crooked Nose by Dissection of Levator Alaque Nasi Muscle.

Background: Nasal base retraction results from cephalic malposition of the alar base in the vertical plane causing disharmonies in the alar base. In literature, there are some excisional procedures to correct this deformity, but it may result to nostril distortion, stenosis, or upper lip elevation. Here, a new technique is reported for the correction of nasal base retraction in crooked nose by manipulating the levator labii alaeque nasi muscle.

Recent Advances in the Treatment of Immune-Mediated Inflammatory Diseases.

The treatment of immune-mediated inflammatory diseases (IMIDs) has dramatically improved over the last two decades by the development of a series of targeted biological therapies. This paper focuses on new developments in the treatment of IMIDs. In particular, we discuss how different ways of targeting the same mediators can lead to different efficacy and safety profiles, using B cell targeting as example.

Anti-interleukin 6 receptor therapy for hyper-IgD syndrome.

Hyper-IgD syndrome (HIDS) is a rare, severe hereditary autoinflammatory disease characterised by periodic fevers, elevated serum IgD levels and a wide range of symptoms. Although a few randomised controlled trials have been performed in this disorder, there are no straightforward treatment protocols and none of the potential therapies are registered for this indication. We report a case of a young woman with severe HIDS who failed numerous therapies.

Dynamic Contrast-Enhanced Magnetic Resonance Imaging Using Pharmacokinetic Modeling: Initial Experience in Patients With Early Arthritis.

Objective: Analysis of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) using pharmacokinetic modeling (PKM) provides quantitative measures that mirror microvessel integrity and can be used as an objective marker of the level of synovial inflammation. The aim of this study was to investigate the PKM parameters K(trans) , kep , and ve in a prospective cohort of disease-modifying antirheumatic drug (DMARD)-naive patients with early arthritis, and to validate the results by assessing their correlation with the number of synovial endothelial cells (ECs).

Methods: Forty-seven patients with early arthritis (arthritis duration <1 year, DMARD naive; comprising 14 patients with rheumatoid arthritis, 22 with unclassified arthritis, 6 with spondyloarthritis [SpA], and 5 with other arthritides) were included.

Does "smoker's paradox" exist in clopidogrel-treated Turkish patients with acute coronary syndrome.

Previously conducted studies revealed that smoking enhanced the efficacy of clopidogrel by increasing formation of the active metabolite (AM) from the prodrug through induction of the cytochrome CYP1A2. The expression of cytochrome enzymes depends on genotype and no data exists in literature conducted in Turkish patients comparing the clopidogrel responsiveness between active smokers and non-active smokers treated with clopidogrel. In this study, our aim was to investigate the clopidogrel responsiveness in clopidogrel-treated Turkish acute coronary syndrome (ACS) patients according to their smoking status.

Prognostic value of neutrophil-to-lymphocyte ratio in pulmonary arterial hypertension.

Objective: To evaluate the prognostic value of baseline neutrophil-to-lymphocyte ratio (NLR) in the prediction of long-term mortality in patients with pulmonary arterial hypertension (PAH).

Methods: This prospective study recorded NLR during initial diagnostic right-sided cardiac catheterization in adult patients with PAH. Demographic, clinical, laboratory and haemodynamic variables were compared by NLR tertile.

Sonographic short-term follow-up after surgical decompression of the median nerve at the carpal tunnel: a single-center prospective observational study.

OBJECT Carpal tunnel syndrome causes increased cross-sectional area (CSA) of the median nerve, which can be assessed by high-definition ultrasonography. It is unclear today, however, whether high-definition ultrasonography may play a role in the postoperative period. This prospective study aimed to determine the natural history of the morphology of the median nerve at the carpal tunnel after surgical decompression assessed by high-definition ultrasonography.

Nuclear Factor-κB-inducing Kinase Is Expressed in Synovial Endothelial Cells in Patients with Early Arthritis and Correlates with Markers of Inflammation: A Prospective Cohort Study.

Objective: The nuclear factor-κB (NF-κB) family of transcription factors is strongly involved in synovial inflammation. We have previously shown that NF-κB-inducing kinase (NIK) is a key regulator of inflammation-induced angiogenesis in rheumatoid arthritis (RA) synovial tissue (ST). Here, we investigated synovial NIK expression in patients with early arthritis and in autoantibody-positive individuals at risk of developing RA.

A New Technique to Correct Saddle Nose Deformity in Failure of Diced Cartilage Grafts: Diced Cartilage Flap.

Background: To correct saddle nose deformity, diced cartilage grafts have been commonly used over the past decade. However, following the correction of saddle nose deformity with diced cartilage graft, some problems like graft absorption or displacement may occur, which require revision surgery. Here, a new technique is presented for correcting saddle nose deformity when diced cartilage graft fails.

A comparison of results of 3-dimensional gait analysis and observational gait analysis in patients with knee osteoarthritis.

Objective: This study aimed to investigate levels of validity, and inter- and intra-observer reliability of observational gait analysis (OGA) in clinical usage, done by the physical therapists with varying clinical experience, in subjects with knee osteoarthritis.

Methods: The study included 33 subjects (22 female, 11 male; mean age: 58.24±9.

Salt-sparing diuretic action of a water-soluble urea analog inhibitor of urea transporters UT-A and UT-B in rats.

Inhibitors of kidney urea transporter (UT) proteins have potential use as salt-sparing diuretics ('urearetics') with a different mechanism of action than diuretics that target salt transporters. To study UT inhibition in rats, we screened about 10,000 drugs, natural products and urea analogs for inhibition of rat UT-A1. Drug and natural product screening found nicotine, sanguinarine and an indolcarbonylchromenone with IC50 of 10-20 μM.

Tertiary Lymphoid Structures in Rheumatoid Arthritis: NF-κB-Inducing Kinase-Positive Endothelial Cells as Central Players.

Tertiary lymphoid structures (TLSs) in chronic inflammation, including rheumatoid arthritis (RA) synovial tissue (ST), often contain high endothelial venules and follicular dendritic cells (FDCs). Endothelial cell (EC)-specific lymphotoxin β (LTβ) receptor signaling is critical for the formation of lymph nodes and high endothelial venules. FDCs arise from perivascular platelet-derived growth factor receptor β(+) precursor cells (preFDCs) that require specific group 3 innate lymphoid cells (ILC3s) and LTβ for their expansion.

Acupuncture relieves symptoms in chronic prostatitis/chronic pelvic pain syndrome: a randomized, sham-controlled trial.

Background: There are multiple approaches to the management of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS); and lately the data suggesting the ability of acupuncture treatment to decrease pain, positively impact quality of life and potentially modulate inflammation has suggested it as a potential therapeutic option for men with CP/CPPS. We conducted this study to determine whether acupuncture is really an effective therapeutic modality for CP/CPPS in terms of >50% decrease in total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score from baseline compared with sham.

Methods: One hundred patients with CP/CPPS (category III B) in an outpatient urology clinic were randomized to receive acupuncture at either seven acupoints bilaterally or sham points adjacent to these points.
