Abstract
Catastrophic antiphospholipid syndrome (CAPS) is a rare and fatal condition that is characterized by diffuse venous and/or arterial thromboembolism within a short period of time and histopathological confirmation of small-vessel occlusion in at least one organ or tissue in the presence of positive antiphospholipid antibodies. Here we report the case of a 19-year-old woman with CAPS. During the first week of her hospitalization, she was diagnosed with CAPS on the basis of skin necrosis, pulmonary artery thrombosis, cerebral venous sinus thrombosis, and positive lupus anticoagulant. She was treated with corticosteroids, intravenous immunoglobulins, plasmapheresis, and anticoagulants. Forty days after the onset of CAPS, cutaneous lesions were recurred during skin surgery. She required a high dose of corticosteroids, intravenous immunoglobulins, and rituximab. No further thrombotic events occurred. Rituximab may be an effective treatment option for patients with CAPS.

Abstract
Granulomatosis with polyangiitis (GPA) is a systemic necrotizing granulomatous disease that involves small- and medium-sized arteries and affects the main respiratory tracts and kidneys. Upper respiratory tract involvement usually occurs in 90% of patients, who most frequently present with symptoms of chronic sinusitis. Subglottic stenosis (SS) is a rare and severe complication that is usually observed in approximately 15% of patients. Here we present a case of SS in a patient with limited form of GPA during remission.

Abstract
Antiphospholipid syndrome (APS), a leading entity in acquired thrombophilia, is characterized by recurrent thrombosis, morbidity in pregnancy and presence of antiphospholipid antibodies (APA). Although the etiopathogenesis is unclear, APA against negatively charged phospholipids and phospholipid-protein complexes are held responsible for the clinical picture. In case of acute thrombosis due to APS, thrombolytic therapy is not a commonly administered treatment option. Here, we present a case with acute thrombosis in the left renal artery showing partial response to thrombolytic therapy.

Abstract
The clinical and laboratory parameters widely used are not specific to discriminate the abdominal pain due to FMF attack from that of acute appendicitis. The present study aims to investigate the urinary beta-2 microglobulin (U-β2M) level as a potential parameter to identify these two diseases mimicking each other. A total of 51 patients with established FMF diagnosis due to Tel Hashomer criteria on colchicine treatment (1-1.5 mg/day), 15 patients with acute appendicitis who had appropriate clinical picture and were also supported pathologically after the surgery, and 20 healthy controls were enrolled in the study. Of the 51 patients with FMF, 25 were at an attack period, while remaining 26 were not. For the diagnosis of acute attack, as well as physical examination, laboratory tests including white blood cell count, C-reactive protein, and erythrocyte sedimentation rate were performed. From urine specimens U-β2M, microalbumin, and N-acetyl glucosaminidase (U-NAG) were measured. U-β2M levels were significantly higher in acute appendicitis group compared to FMF attack, FMF non-attack, and control groups (p < 0.001, p < 0.001, and p < 0.001, respectively). U-NAG and microalbuminuria were significantly higher in acute appendicitis, FMF attack, and FMF non-attack groups compared to controls (U-NAG p < 0.001, p = 0.016, p = 0.004, microalbuminuria p < 0.001, p < 0.001, p < 0.001, respectively). Microalbuminuria was significantly higher in acute appendicitis group compared to the FMF attack group (p = 0.004). Determination of U-β2M levels may be helpful for differential diagnosis of peritonitis attacks of FMF patients on colchicine treatment and acute appendicitis. However, this finding should be substantiated with other studies.

Abstract
Inflammatory myopathies are a heterogeneous group of diseases with unknown etiology characterized by inflammation of the skeletal muscles and proximal muscle weakness. Dermatomyositis (DM) is an idiopathic inflammatory myopathy with characteristic cutaneous findings such as heliotrope rash, Gottron's sign, Gottron's papules, shawl sign and machinist hand. Amyopathic dermatomyositis (ADM) is a rare but well-recognized clinical subtype of DM, constituting aproximately 10-20% of patients with this disease. It generally manifests only pathognomonic skin findings without clinical and laboratory evidence of muscle involvement. In this report, we present a rare case of ADM associated with interstitial pulmonary disease.

Abstract
AIM Rheumatoid arthritis (RA) is an inflammatory autoimmune disease with unknown etiology and systemic involvement. Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are two new inflammatory markers used in the assessment of systemic inflammation. The aim here is to study NLR and PLR in patients with RA to investigate their relation with Disease Activity Score of 28 joints (DAS-28). METHODS The study included 104 patients with RA and a control group of 51 age- and gender-matched healthy subjects. We divided the patients into two groups according to the DAS-28 score. Group 1 included patients with a score of lower than 2.6 by the DAS-28 (patients in remission) and Group 2 included patients with a score of 2.6 and higher (patients with active disease). RESULTS NLR was 2.12 ± 0.83 in the patient group and 1.58 ± 0.57 in the control group. PLR was 136.50 ± 53.52 in the patient group and 114.84 ± 29.41 in the control group. There was a statistically significant difference in NLR and PLR between the patient and control groups (P ≤ 0.0001 and P = 0.001, respectively). Patients in Group 1 had an NLR of 1.84 ± 0.61 and a PLR of 119.25 ± 41.77. Patients in Group 2 had an NLR of 2.29 ± 0.90 and a PLR of 147.28 ± 56.96. There was a statistically significant difference in NLR and PLR between the two groups (P = 0.003 and P = 0.005 respectively). A correlation was observed between NLR and PLR by DAS-28 (r = 0.345, P ≤ 0.0001 and r = 0.352, P ≤ 0.0001, respectively). CONCLUSIONS The present study showed us that NLR and PLR were two new inflammatory markers which could be used to assess disease activity in patients with RA.

Abstract
OBJECTIVE Knowledge about the inhibition of centrally located angiotensin-I (AT-I) receptors by highly lipophilic AT-I receptor blockers and its' effect are limited with experimental studies. Thus, we aimed to investigate the effect of Telmisartan on Inter-dialytic weight gain (IDWG) % and echocardiographic measurements in anuric hemodialysis (HD) patients. PATIENTS AND METHODS A total of forty-one anuric HD patients with ≥ 6 months maintenance on HD were included in this prospective, randomized and self-controlled study. Four weeks prior the study, angiotensin converting enzyme blockers and AT-I receptor blocker drugs were stopped. Patients were assessed three times during the study protocol. These are baseline, three months later (without Telmisartan period) and three months after Telmisartan therapy. RESULTS IDWG % was significantly decreased in the period of with Telmisartan compared to period without Telmisartan (5.6 ± 1.0% vs 5.3 ± 1.0%, p = 0.03). After the administration of Telmisartan left ventricule end-diastolic diameter (LVEDD) (p = 0.001) and inferior vena cava diameter (IVCD) (19.1 ± 3.8 mm vs 17.3 ± 4.2 mm, p = 0.001) were significantly decreased compared to the period of without Telmisartan. Despite of significantly changes observed in IVCD and LVEDD measurements in a period without Telmisartan, there was no significantly difference in left ventricular mass index (LVMI) measurements in this period. However, LVMI was significantly regressed after the administration of Telmisartan (269.3 ± 82.7 g vs 256.3 ± 70.3 g, p = 0.003 respectively). CONCLUSIONS Treatment of anuric HD patients with Telmisartan at a dose of 40 mg a day reduces IDWG%, LVEDD and IVCD measurements. Further studies investigating the long-term effect of these beneficial effects on clinical outcomes are necessary.

Abstract
OBJECTIVE Ankylosing spondylitis (AS) is a progressive chronic inflammatory disease mainly characterized by axial skeleton and sacroiliac joint involvement. We aimed to investigate the relation between neutrophil-to-lymphocyte ratio (NLR) and disease severity of AS and to explore its availability in clinical practice. METHODS A total of 102 AS patients and 60 individuals who were age- and gender-compatible with the control group were included into the study. Patients were divided into 2 groups according to Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores. Patients with BASDAI scores < 4 were considered to be having mild disease activity, whereas those with scores ≥ 4 were considered to be displaying severe disease activity. Hemogram test during the diagnosis, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and other laboratory values of the control group were recorded. RESULTS NLR was observed to be higher in AS patients compared to the controls (2.47 ± 1.33 and 1.72 ± 0.47; respectively; p<0.0001). NLR was observed to be significantly higher in severe AS disease activity compared to the mild AS disease activity (2.72 ± 1.41, 2.20 ± 1.19; respectively; p = 0.001). NLR had statistical significant differences between mild disease activity compared to the controls (2.20 ± 1.19 and 1.72 ± 0.47, respectively; p = 0.263). There was a positive correlation between NLR and BASDAI (r = 0.193, p = 0.041). The performance of NLR evaluating the disease severity by Roc analysis had sensitivity of 69%, specificity of 54% (cut-off value 1.91), and AUC of 0.652 (95% Cl, 0.549-0.755) (p = 0.006). CONCLUSIONS NLR may be a simple and inexpensive marker to indicate disease activity in patients with AS in daily clinical practice (Tab. 3, Fig. 3, Ref. 25).

Abstract
OBJECTIVE Plasma interleukin-18 (IL-18) has been reported to be associated with homeostasis model assessment of insulin resistance (HOMA-IR). It also has been described as one of the factors that, in addition to insulin resistance, may also contribute to atherosclerosis. Parameters of systemic inflammation are also significantly associated with circulating IL-18. Our objective was to investigate whether IL-18 is associated with insulin resistance and atherosclerosis in patients with rheumatoid arthritis (RA) in which accelerated atherogenesis develops. MATERIAL AND METHODS Fifty-one female RA patients and 30 female controls were enrolled in the study; 31 of them were without disease-modifying antirheumatic drug (DMARD) treatment and had a relatively short disease duration. Disease activity was assessed by Disease Activity Score (DAS) 28 index. HOMA-IR method was used to detect insulin resistance. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), fasting plasma glucose (FPG), insulin, tumor necrosis factor alpha (TNF-α), and IL-18 levels were evaluated. Also, carotid intima-media thickness (cIMT) was measured. RESULTS There were no differences between patients and the control group according to age, sex, and body mass index. ESR, CRP, insulin, FPG, HOMA-IR, TNF-α, IL-18 levels, and cIMT measurements were significantly high in the patient group. HOMA-IR and cIMT measurements were similar and high in both the DMARD and non-DMARD patient groups. HOMA-IR correlated with TNF-α (r=0.308, p=0.028), but no correlation was found between IL-18 and HOMA-IR. However, IL-18 was correlated positively with cIMT (r= 0.318, p=0.028) and negatively with BMI (r=-0.360, p=0.01). CONCLUSION IL-18 is associated with atherosclerosis in RA patients. However, no significant relation was found with insulin resistance. IL-18 may be a marker for early evaluation of atherosclerosis in RA patients.

Abstract
Behcet's disease (BD) is a chronic, inflammatory, and multisystemic condition although its pathogenesis is uncertain. Main component of St. John's wort (Hypericum perforatum, HP) is hyperforin and induces antiinflammatory and antioxidant properties. We aimed to investigate effects of HP on oxidative stress, apoptosis, and cytosolic-free Ca²⁺ [Ca²⁺](i) concentration in neutrophil of BD patients. Nine new-diagnosed active patients with BD and nine control subjects were included in the study. Disease activity was considered by clinical findings. Neutrophil samples were obtained from the patients and controls. The neutrophils from patients were divided into three subgroups and were incubated with HP, voltage-gated calcium channel (VGCC) blockers, (verapamil+dilitiazem) and non-specific TRPM2 channel blocker (2-aminoethyl diphenylborinate, 2-APB), respectively. The neutrophils were stimulated by fMLP as a Ca²⁺-concentration agonist and oxidative stress former. Caspase-3, caspase-9, apoptosis, lipid peroxidation, and [Ca²⁺](i) values were high in the patient groups, although cell viability, glutathione (GSH), and glutathione peroxidase (GSH-Px) values were low in patient group. However, the [Ca²⁺](i), caspase-3, and caspase-9 values decreased markedly in patient+HP group although GSH and GSH-Px values increased in the group. The [Ca²⁺](i) concentration was also decreased in the patient group by V+D, 2-APB, and HP incubations. In conclusion, we observed the importance of neutrophil Ca²⁺ entry, apoptosis, and oxidative stress through gating VGCC and TRPM2 channels in the neutrophils in the pathogenesis and activation of the patients with BD. HP induced protective effects on oxidative stress by modulating Ca²⁺ influx in BD patients.

Abstract
OBJECTIVES The aims of this study are to evaluate the dentofacial morphology of patients with rheumatoid arthritis (RA) and to compare the morphological data with those of healthy age- and sex-matched control subjects. METHODS Twenty-seven RA patients (mean age, 45.77 ± 8.64 years) and 25 healthy subjects (mean age, 44.80 ± 8.24 years) participated in this prospective study. Clinical and functional evaluations of the RA patients were assessed. The erythrocyte sedimentation rate, C-reactive protein level, rheumatoid factor level, and anti-citrullinated peptide antibodies (ACPA) titers of RA patients were determined, and DAS28 scores were calculated. Linear and angular measurements were performed on cephalometric tracings and condylar erosion was evaluated on lateral panoramic radiographs. Statistical comparison of the two groups was performed with an independent samples t test. Pearson correlation analysis was used to assess the relationship between the clinical and laboratory parameters. RESULTS Based on DAS28 scores, no patient with RA was in the remission period, 3 patients had low, 23 had medium, and 1 had high disease activity. Sixteen (59.26 %) patients with RA had positive ACPA titers. Lateral cephalometric radiographs revealed statistically significant difference between the two groups for the measurement of U1-NA (millimeter; p = 0.047), U1-NA (degrees; p = 0.031), L1-NB (degrees; p = 0.030), IMPA (L1-MP; p = 0.001), interincisal angle (U1-L1; degrees; p = 0.022) and midface length (Co-A; millimeter; p = 0.033). A significant positive linear correlation was found between disease duration time and DAS28 scores (r = 0.066, p = 0.040). CONCLUSIONS Dentoalveolar effects of RA on dentofacial morphology are more significant than the skeletal effects. Future studies with larger sample sizes are required to evaluate the exact effects of RA on dentofacial morphology. CLINICAL RELEVANCE Clinicians should consider the fact that RA-associated dentoalveolar changes can be observed and may affect the orthodontic treatment process.

Abstract
Gout results from multifactor interactions between gender, age, genetic and environmental factors. Environmental factors underlying gout and precipitating factors triggering acute attacks might vary in different populations with different lifestyles. In this study, we aimed to collect data regarding the demographic and clinical features, comorbid factors, and precipitating factors associated with the initiation of acute attacks in gout patients in Turkey. A total of 312 patients were included in this study (mean age, 58.8 ± 13.8 years; female/male ratio, 55/257). The demographic features, alcohol intake, clinical and laboratory features, and comorbid conditions including obesity, diabetes mellitus, hyperlipidemia, hypertension, and coronary heart disease were noted in a standard questionnaire. Precipitating factors initiating acute attacks (if any) were also noted. The patients were divided into 4 groups according to the region of location as central Anatolian region, southeast Anatolian region, Aegean region, and Trakya region. Our results were compared according to the gender and the location of the patients. The mean age at the start of the symptoms was 10 years higher in women (60.4 ± 14.8 and 50.6 ± 13.5 years in women and men, respectively, p < 0.001).Obesity was present in 40.1 %, diabetes mellitus in 17.9 %, hyperlipidemia in 30.1 %, hypertension in 53.5 %, coronary artery disease in 17 %, and nephrolithiasis in 21.8 % of patients. Precipitating factors triggering gout flares were as follows: diet (high consumption of meat or fish) in 46.5 %, alcohol consumption in 15.7 %, diuretics in 8.3 %, diet or diuretics in 5.1 %, diet or alcohol in 4.5 %, diet or alcohol or diuretics in 1.6 %, others in 4.2 %, and none in 14.1 %. The presence of diabetes and diuretic use was more common among women. Use of diuretics is a more common trigger for gout flares among women. On the other hand, various comorbid conditions, such as obesity and hypertension, and triggers for gout flares may differ between patients living in different geographic regions. In summary, we reported the first data regarding clinical and demographic characteristics of gout in Turkey. The majority of our patients could describe at least one "trigger" that initiated gout flare. Both comorbid conditions and triggers of attack might differ between men and women, and in different geographic areas. Better knowledge of the modifiable risk factors can be useful for the management strategy to optimize long-term patient outcomes in local clinics.

Abstract
The aim of this study was to investigate the clinical, radiographic, and magnetic resonance imaging (MRI) findings of temporomandibular joint (TMJ) and masticatory muscles in rheumatoid arthritis (RA) patients. Twenty-eight RA patients and 29 healthy subjects were participated in the study. The patient underwent clinical and laboratory investigation. DAS28 scores were calculated. Lateral panoramic radiography was performed to evaluate condylar erosion and condylar movement. Craniofacial MRI was performed to evaluate TMJ and masseter, medial and lateral pterygoid muscles' thickness, and cross-sectional area. It was found that the mean maximal interincisal distance, range of lateral, retrusive (P < 0.05) and protrusive motion were all lesser in RA group. Lateral panoramic radiography revealed a distinct erosion in 10.7% (3/28) and restricted condylar movement in 53.6% (15/28) of RA patients. Two RA patients demonstrating marked condylar erosion in lateral panoramic radiographs were RF negative and had DAS28 scores 3.41 and 4.61. MRI findings revealed condylar erosion and effusion in one RA patient and atrophic changes of masticatory muscles in another patient. There was no statistical significance between RA and healthy groups for the thickness and cross-sectional areas of the masticatory muscles. RA group revealed a strong linear relationship for the right and left muscle thickness and cross-sectional areas in regression analysis. TMJ symptoms are frequent findings and thought to be affected from mean disease duration in RA. Laboratory findings should be considered for disease activity-related TMJ involvement. RA patients did not present muscular atrophy or hypertrophy.

Abstract
Although so many studies exist on effect of fluoride on hematological parameters in experimental animals, a few studies have been conducted to investigate the effects of chronic fluorosis on hematological parameters in humans' subjects with endemic fluorosis. So we aimed to determine the hematological parameters in patients with endemic fluorosis. The study group consisted of 60 patients with endemic fluorosis (27 females, 33 males, and mean age 33.4 ± 9.6 years). An age-, gender-, and body mass index-matched control group was composed of 34 healthy volunteers (11 females, 23 males with a mean age 32.6 ± 5.6 years). Urine fluoride levels of fluorosis patients were significantly higher than control subjects as expected (0.42 ± 0.09 vs 1.92 ± 0.14 mg/l, respectively; P < 0.001). There were no statistically significant differences between the fluorosis group and control group with respect to hematological parameters (complete blood count and ferritin). We concluded that chronic fluorosis has no effect on hematological parameters in patients with endemic fluorosis.
