RESUMO
BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic multi-systemic autoimmune disease. SLE patients may experience a wide range of physical, psychological, and social perception of well-being influenced by the patient illness that are not always fully captured by descriptions of the disease's physiological consequences alone. Nowadays, patients with SLE have a better survival than decades ago, nevertheless still experience a low health related quality of life (HRQoL). Assessing disease activity in SLE is crucial to the physician as it forms the basis for treatment decisions, moreover careful evaluation for respiratory involvement should be routinely considered. More chronic lung disease related to SLE can have a significant negative effect on patient well-being and physical performance status and are detrimental to quality of life. OBJECTIVE: The aim of this study was to evaluate quality of life changes in SLE patients using Lupus QoL scale, assessing their correlation with different disease aspects particularly pulmonary manifestations and predictors for worse QoL. MATERIALS AND METHODS: Total of 60 SLE patients, who fulfilled the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria, were enrolled in this study. Disease activity was measured by systemic lupus erythematosus disease activity index (SLEDAI) and quality of life was assessed by Lupus QoL. Pulmonary evaluation included pulmonary function tests parameters (PFTs), mMRC dyspnea scale, HRCT score, and pulmonary damage index. RESULTS: Lupus QoL had a strong significant correlations with PFTs FEV1, FVC, and DLCO (r = 0.79, 0.78, 0.76, p < .001), respectively}, while Lupus QoL had strong negative correlations with both mMRC dyspnea scale and HRCT score (r = -0.96, -0.85, p < .001), respectively, and moderate negative correlation with neuropsychiatric lupus (NPSLE) (r = -0.61, p < .001). Weak negative correlations were found between Lupus QoL, photosensitivity, alopecia, Raynaud's and renal affection (r = -0.29, -0.30, -0.30, 0.38, p = .03, .02, .02, .002), respectively. NPSLE and pulmonary involvement were the most consistent predictors of low HRQoL [contributing 36% and 18% of the variance of Lupus QoL], respectively. CONCLUSION: Lupus QoL is negatively correlated with different SLE clinical parameters particularly pulmonary manifestations. Neuropsychiatric, pulmonary, renal affection, and SLEDAI are the best determinants for worse Lupus QoL.

BACKGROUND: Although the significance of inflammatory cytokines and chemokines in the pathogenesis of SLE is well established, the findings showed diversity and implied that combining different biomarkers could be useful in monitoring disease activity or organ involvement. Despite the potentially high prevalence of lung involvement in SLE, only a few studies have investigated for lung biomarkers. OBJECTIVE: The aim of this study was to assess the value of Chemokine Ligand 21 (CCL 21) and Interferon gamma-induced protein 10 (IP10) as serum biomarkers for pulmonary involvement in SLE and their correlation with disease activity, organ involvement, pulmonary function tests (PFTs), and chest CT findings. MATERIALS AND METHODS: Sixty SLE patients and 30 age- and sex-matched controls were enrolled into this study. All patients underwent serological tests, PFTs, and chest CT examination. The serum levels of CCL21 and IP10 were analyzed, and their correlations with PFTs and CT were explored. RESULTS: SLE patients with pulmonary involvement had higher serum CCL21 and IP10 levels compared to those without pulmonary involvement which in turn had higher levels than the controls. There were strong negative correlations between CCL21 and IP10 and FEV1, FVC, and DLCO. There were also strong correlations between both biomarkers and HRCT and pulmonary damage, but no correlation with other disease manifestations. Serum level of 2095 pg/mL for CCL21 and 7185 pg/mL for IP10 could detect pulmonary involvement in SLE with a sensitivity of 83.7% and a specificity of 94.1%. Both biomarkers performed equally well in detecting SLE pulmonary involvement with a strong agreement between them (κ = 0.86, p < .001), but CCL21 was better correlated with PFT abnormalities. CONCLUSION: Both CCL21 and IP10 are serum biomarkers to detect pulmonary involvement in SLE with high sensitivity and specificity. CCL21 correlates better with PFT abnormalities.

Cone-beam computed tomography (CBCT) has become popular, and its many inherent advantages are indisputable. Nevertheless, CBCT is prescribed cautiously because the radiation dosage is higher than that of conventional radiography. When and to what extent should CBCT be prescribed for orthodontic patients? The purpose of this article is to present 4 curious cases in which a considerable discrepancy was found between the conventional panoramic radiograph and the CBCT view. Is it time to spare patients an unnecessary conventional panoramic radiograph and shift to CBCT for all patients?

The aim of this study was to find the correlation between severity of dry eye and rheumatoid arthritis (RA) disease activity. Forty- two RA patients with dry eye were recruited from Rheumatology Outpatient Clinic in Minia University Hospital. Assessment of RA disease activity was performed using disease activity score (DAS-28). Ocular tests include Schirmer test I, tear film break up time (TBUT) and ocular staining score (OSS) was performed by ophthalmologist to find evidence of ocular dryness. Erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), anti SSA/Ro and anti SSB/La was also tested. Patients with severe dry (OSS ≥ 3) underwent minor salivary gland biopsy (MSGB) as suspected to have secondary Sjögren's syndrome (SS). Of 42 RA patients, 30 had definite dry eye. DAS-28 did not show significant correlation with any of ocular tests for dryness while the duration of RA was significantly positively correlated with Schirmer test and OSS. The biopsy results of RA patients with severe dry eye show no evidence of SS. The severity of dry eye is not correlated with activity of RA but with its duration.

PURPOSE: To assess the frequency of SjÓ§gren's syndrome (SS), either primary or secondary to rheumatic disease, in a cohort of patients with aqueous-deficient dry eye and to determine the most accurate objective test for diagnosis of SS. METHODS: A total of 111 patients with dry eye were recruited from Minia University's âOphthalmology Outpatient Clinic (69 patients) and Rheumatology Outpatient Clinic (42 patients). The patients were screened for aqueous tear-deficient dry eye by abnormal test results of Schirmer test I (<10 mm) and tear-film break-up time (<10 seconds) in at least one eye. The diagnosis of SS was made according to the 2012 American College of Rheumatologyâ criteria. A complete work up for SS was performed, including clinical examination, serological tests, ocular tests, and labial salivary-gland biopsy (LSGB). RESULTS: Of the 111 patients, 58 had aqueous-deficient dry eye: 23 in the ophthalmology clinic cohort (group I) and 35 in the rheumatology clinic cohort (group II). Three patients had pSS, and its frequency was 13% in group I and 5.2% among all studied patients. The ocular staining score is the most diagnostic ocular test (sensitivity 100% and specificity 90.9%). Anti-SSA/Ro antibody is the most accurate serological method (sensitivity 33.3% and specificity 100%). LSGB histopathology is the most diagnostic method for SS, with sensitivity, specificity, and positive and negative predictive values of 100%. CONCLUSION: SS was detected with reasonable frequency among dry-eye patients, particularly pSS. Screening of dry eye for SS can select SS patients early in the disease course.
RESUMO
OBJECTIVE: To assess the validity of ultrasound (US) in the early detection of arthritis and enthesitis, with assessment of the validity of magnetic resonance imaging (MRI) in the early detection of sacroiliitis and spondylitis in patients with psoriasis and to compare the findings of clinical examination and conventional radiography. MATERIAL AND METHODS: The study included 50 patients with psoriasis and 20 healthy controls. All patients and controls underwent US and power Doppler analyses for the joints of both hands and feet and the entheseal sites. MRI of the lumbosacral spine and sacroiliac joints was performed. RESULTS: Abnormal US findings of arthritis were present in 18% patients, whereas only 6% patients had X-ray abnormalities, the enthesopathy represent 74%, at a higher percentage than clinical and radiological assessment (46, 26% respectively). MRI and radiological study demonstrated evidence of inflammation in the spine in 44% and 16% patients, respectively, and evidence of sacroiliitis in 10% and 6% patients, respectively. CONCLUSION: Use of newer imaging modalities allows early diagnosis and early initiation of therapy.
RESUMO
INTRODUCTION: A great number of nickel-titanium (NiTi) rotary systems with noncutting tips, different cross-sections, superior resistance to torsional fracture, varying tapers, and manufacturing method have been introduced to the market. The purpose of this study was to evaluate and compare the effect of 4 rotary NiTi preparation systems, Revo-S (RS; Micro-Mega, Besancon Cedex, France), Twisted file (TF; SybronEndo, Amersfoort, The Netherlands), ProFile GT Series X (GTX; Dentsply, Tulsa Dental Specialties, Tulsa, OK), and ProTaper (PT; Dentsply Maillefer, Ballaigues, Switzerland), on volumetric changes and transportation of curved root canals. METHODS: Forty mesiobuccal canals of mandibular molars with an angle of curvature ranging from 25° to 40° were divided according to the instrument used in canal preparation into 4 groups of 10 samples each: group RS, group TF, group GTX, and group PT. Canals were scanned using an i-CAT CBCT scanner (Imaging Science International, Hatfield, PA) before and after preparation to evaluate the volumetric changes. Root canal transportation and centering ratio were evaluated at 1.3, 2.6, 5.2, and 7.8 mm from the apex. The significance level was set at P ≤ .05. RESULTS: The PT system removed a significantly higher amount of dentin than the other systems (P = .025). At the 1.3-mm level, there was no significant difference in canal transportation and centering ratio among the groups. However, at the other levels, TF maintained the original canal curvature recording significantly the least degree of canal transportation as well as the highest mean centering ratio. CONCLUSIONS: The TF system showed superior shaping ability in curved canals. Revo-S and GTX were better than ProTaper regarding both canal transportation and centering ability.

INTRODUCTION: Pulmonary arterial hypertension (PAH) is a serious and often fatal complication of systemic lupus erythematosus (SLE). Because the diagnosis of PAH often is made years after symptom onset, early diagnostic strategies are essential. Doppler echocardiography currently is considered the noninvasive screening test of choice for evaluating pulmonary hypertension. AIM: Screening for asymptomatic pulmonary hypertension in systemic lupus erythematosus patients using Doppler echocardiography, and correlating it with inflammatory parameters of the disease. PATIENTS AND METHODS: Doppler echocardiography was performed in 74 patients with systemic lupus erythematosus over one year (66 adult and 8 juvenile), adult SLE included 57 patients with adult-onset and 9 patients with childhood-onset. Pulmonary hypertension was diagnosed if the peak systolic pressure gradient at the tricuspid valve was more than 30 mmHg. All patients were subjected to full history taking, rheumatological examination, laboratory studies and chest x-ray. RESULTS: In seventy four SLE patients, the pulmonary hypertension was detected in 8 patients (10.8%), 7 adult-onset SLE patients (aged from 19 to 30 years) and 1 juvenile SLE (aged 12 years). The range of pulmonary artery systolic pressure was 34-61.2 mmHg (43.19 ± 9.28). No significant differences between patients with and those without pulmonary hypertension as regard clinical features. Significantly higher frequencies of rheumatoid factor and anti-cardiolipin antibodies were found in patients with pulmonary hypertension versus those without (P = 0.02, P = 0.008 respectively). Positive rheumatoid factor and ACL were significantly associated with occurrence of PAH in SLE (P = 0.007, P = 0.006 respectively). No significant correlations were found between pulmonary artery pressure, disease duration, SLE Disease Activity Index (SLEDAI), ESR, and anti-ds DNA. CONCLUSION: Patients with SLE have an increased risk of pulmonary arterial hypertension. Echocardiography should be used as a screening tool in patients at high risk for development of pulmonary hypertension. Positive anti-cardiolipin antibodies and rheumatoid factor were significant predictors of pulmonary hypertension in our study.
