RESUMO
Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with psoriasis. The use of inflammatory markers can be disappointing in PsA since they are elevated in only about half of the patients. This study aimed to measure serum calprotectin level in PsA patients and to assess its association with disease activity in PsA (DAPSA) and musculoskeletal ultrasound findings. The study included 50 PsA patients and 30 controls. All subjects underwent medical history, musculoskeletal examination, hand and wrist joints ultrasound, and laboratory assessment. The mean age of patients was 41.04±11.8 years with female: male ratio of 3:2, and the median duration of arthritis 2 years (1-4 years) and DAPSA 25 years (3-84 years). The most common finding in patients by ultrasound was synovial hypertrophy in wrist joint (32%) followed by hand joints (28%). Patients' serum calprotectin level was significantly higher (174.2 ng/ml; ranged 127.5-282.6 ng/ml) than controls 41.4 ng/ml; ranged 19.9-59.8 ng/ml) (p < 0.001). Serum calprotectin predicted the occurrence of PsA at cutoff >106.4 ng/ml (with sensitivity 98%, and specificity 86.6%; p=0.001) and predicted synovial hypertrophy in hand joints at cutoff >258.9 ng/ml (with sensitivity 71%, and specificity 83%). There was a significant relation between serum calprotectin with synovial hypertrophy (p=0.004), osteophytes (p < 0.0001), nail affection (p=0.03) and erosions (p=0.01). Serum calprotectin is a more potential predictor for PsA (p < 0.0001) compared to erythrocyte sedimentation rate (p=0.005) and C-reactive protein (p=0.001). In conclusion, serum calprotectin level is significantly high in PsA patients. It is associated with small hand joints synovitis and nail changes. This makes it a promising biomarker for defining patients with suspected PsA who do not meet specific disease criteria.

BACKGROUND: Ionizing radiation exposure is an ever-present part of the dental diagnostic process. A public concern often exists due to the misunderstanding of the stochastic effects of dental X-rays. This information can be difficult to explain to the patient since many patients are apprehensive about the subject matter. OBJECTIVE: This article aims to assess the public's knowledge of radiation exposure and estimate the general concern or apprehension about these diagnostic imaging modalities in an effort to understand and therefore ensure patient reassurance during treatment. METHOD: A questionnaire was conducted asking adults between the ages of 18 to 74 in Jeddah, Saudi Arabia questions pertaining to radiation risk. RESULTS: There were 105 respondents; 21.9% showed concerns toward dental imaging, while 20% were skeptical. approximately 74% of respondents believed there was a limit to the amount of radiation exposure a patient could receive for diagnostic purposes, while only eight percent correctly identified that there was no set limit. Only 21.9% knew that a breastfeeding mother could have dental X-rays if need be; 33.3% understood that ionizing radiation from an intra-oral dental X-ray caused less exposure than natural background radiation from a return flight from Jeddah to Dammam. Conclusions: Patients are not aware of ionizing radiation exposure equivalencies between different imaging modalities. A more effective approach to convey exposure risk would be relating the radiation doses to natural background radiation as comparators.
RESUMO
A strong correlation between lupus nephritis (LN), disease activity, and serum beta 2-microglobulin (b2MG) was observed. The current study examines the correlation between serum b2MG and renal involvement, damage score, and disease activity in systemic lupus erythematosus (SLE) patients. One hundred SLE patients from Ain Shams University Hospital were enrolled and categorized into two groups. Group I had 40 patients with negative b2MG, while Group II had 60 patients with positive b2MG levels. Medical history, clinical examination, and assessing disease activity based on SLE disease activity index (SLEDAI-2 K), and damage score were recorded for all patients. Laboratory examinations, such as serum b2MG, complete blood count, blood urea nitrogen (BUN), serum creatinine, glomerular filtration rate (GFR), urine analysis, 24 h urinary protein excretion, Antinuclear antibodies (ANA), anti-dsDNA antibody, and serum complement (C3, C4). BUN, 24 h urinary protein, serum creatinine, active urinary sediment, SLEDAI score, and damage score were all elevated in group II compared to group I (p < 0.001). There is a positive correlation between serum b2MG and 24 h urinary protein, BUN, serum creatinine, disease activity, and damage score (p < 0.001), while it was negatively correlated with GFR, C3, and C4 (p < 0.001). Serum b2MG has proven to be a predictor of LN in SLE patients (Sensitivity 92.45%, Specificity 74.47%), also being a predictor of the activity of the disease as well as damage index (Sensitivity 96.67%, Specificity 85%) (Sensitivity 92.45%, Specificity 74.47%), respectively. Serum b2MG level can be used as a valuable predictor for LN, clinical disease activity, and damage score.

In view of the rapid spread of COVID-19 and the high mortality rate of severe cases, reliable risk stratifying indicators of prognosis are necessary to decrease morbidity and mortality. The aim of the present study was to evaluate the value of serum amyloid A (SAA) and carcinoembryonic antigen (CEA) as prognostic biomarkers in comparison to other predictors, including C-reactive protein (CRP) and ferritin levels. This study included 124 patients diagnosed with COVID-19, and they were assigned to one of two groups: Mild and severe, based on the severity of the infection. Radiological and laboratory investigations were performed, including evaluation of CRP, ferritin, D-Dimer, SAA and CEA levels. Significantly higher levels of CRP, ferritin, D-Dimer, SAA and CEA were observed in severe cases. SAA was significantly correlated with CRP (r=0.422, P<0.001), ferritin (r=0.574, P<0.001), CEA (r=0.514, P<0.001) and computed tomography severity score (CT-SS; r=0.691, P<0.001). CEA was correlated with CRP (r=0.441, P<0.001), ferritin (r=0.349, P<0.001) and CT-SS (r=0.374, P<0.001). Receiver operator characteristic (ROC) curves for performance of SAA, CEA, ferritin, CRP and SAA showed the highest AUC value of 0.928, with a specificity of 93.1%, and a sensitivity of 98.5% at a cut-off of 16 mg/l. The multi-ROC curve for SAA and ferritin showed 100% specificity, 100% sensitivity and 100% efficiency, with an AUC of 1.000. Thus, combining SAA and ferritin may have guiding significance for predicting COVID-19 severity. SAA alone showed the highest prognostic significance. Both SAA and CEA were positively correlated with the CT-SS. Early monitoring of these laboratory markers may thus provide significant input for halting disease progression and reducing mortality rates.
RESUMO
Introduction The temporomandibular joint (TMJ) is an important joint that plays major functions, including dental occlusion, mastication, and facial expressions. Different diseases can affect the TMJ, including chronic inflammatory arthritis. Rheumatoid arthritis (RA) is the most common inflammatory arthritis worldwide associated with TMJ dysfunction. In this study, we assess the prevalence of TMJ among RA patients based on the Fonseca Anamnestic Index. Methods Eighty-one patients with rheumatoid arthritis were interviewed by a trained physician to fulfill the Fonseca Anamnestic Index questionnaire. All participants underwent a medical file review to collect their sociodemographic data, RA duration, co-existing comorbidities, and different lab results. Result According to the Fonseca score, 29.6% had no temporomandibular disorder (TMD) among RA patients, while 39.5% had mild TMD. Only 6% had severe TMD. The female sex and increased body weight were associated with TMJ disease. Conclusion The majority of rheumatoid arthritis patients (70%) suffer from some degree of temporomandibular joint disorder.
RESUMO
OBJECTIVE: This study aims to comprehensively evaluate olfactory and gustatory dysfunctions during the COVID-19 pandemic regarding onset, course, associated symptoms, prognosis and relation to patients' demographics, treatment received and other symptoms. PATIENTS& METHODS: This is a prospective study conducted on patients proven to be infected with COVID-19 and with olfactory/gustatory dysfunction symptoms. Detailed history was taken from each patient about the onset of this dysfunction, associated symptoms. Then follow-up survey was done after 6 months to evaluate the prognosis. RESULTS: 1031 patients were included in the study, aged 18 to 69 years old, with 31.8% were male. Olfactory/gustatory dysfunctions occurred after other COVID-19 symptoms in 43.5% of cases, occurred suddenly in 80.4% and gradually in 19.6%. These dysfunctions were anosmia & ageusia in 50.2%, hyposmia & hypogeusia in 23.3%, anosmia alone in 17.7%, phantosmia in 18%, Parosmia in 28.4%. In terms of recovery 6-month follow up, 680 patients (66%) recovered completely, 22.1% recovered partially while 11.9% did not recover. Most improvement occurred in the first two weeks. Headache, malaise, nasal obstruction and rhinorrhea were the commonest COVID-19 symptoms associated. CONCLUSION: Most recovery of olfactory/gustatory dysfunction in COVID-19 infection occurs at the first two weeks and is unrelated to patient demographics, treatment or olfactory training. Parosmia is an independent predictor for complete recovery, while phantosmia is significantly associated with lower probability of complete recovery.

BACKGROUND: As an immune modulator, vitamin D has been implicated in the coronavirus disease 2019 (COVID-19) severity. This study aimed to investigate the association between vitamin D levels and the severity of COVID-19 infection. METHODS: A cross-sectional study, which included 124 patients diagnosed with COVID-19 and were selected from Ain Shams University Hospitals and assigned to two groups; mild and severe COVID-19. All patients underwent detailed history taking, clinical data, and different laboratory investigations as complete blood count, blood urea nitrogen, serum creatinine, liver enzymes, C-reactive protein, D-dimer, ferritin and serum vitamin D concentration. In addition to findings of initial chest computed tomography (CT) were recorded. COVID-19 Reporting and Data System (CO-RADS) and CT chest severity scores (CT SS) were reported. RESULTS: In this study of 124 COVID-19-positive individuals, a high prevalence of hypovitaminosis D was found (97.6%). Lower vitamin D levels were significantly associated with more severe COVID-19 cases (p-value < 0.001), higher blood levels of inflammatory markers including (D-dimer, CRP, and ferritin), a higher CT SS and longer disease duration. Serum vitamin D can be used as a predictor for the severity of COVID-19 infection with a specificity of 96.6%, and sensitivity of 45.5%. CONCLUSION: The high frequency of hypovitaminosis D in severe COVID-19 patients provides further evidence of a potential link to poor prognosis and severity of the disease, so vitamin D deficiency may be a marker of poor prognosis in these patients.

OBJECTIVE: This study was conducted to estimate the frequency of anti-nuclear antibodies (ANAs), anti-dsDNA, and anti-extractable nuclear antigen (ENA) antibodies in juvenile systemic lupus erythematosus (JSLE) patients and their association with different clinical manifestations and disease activity. PATIENTS AND METHODS: A cross-sectional study that includes 100 JSLE patients from Ain Shams University Hospital was conducted. All subjects underwent history taking, clinical examination, assessment of disease activity based on the SLE disease activity index (SLEDAI), laboratory investigations, and tests for autoantibodies, namely ANA, anti-dsDNA, and anti-ENA antibodies, including anti-Ro (SSA), anti-La (SSB), anti-Smith (Sm), and anti-U1-ribonucleoprotein (U1-RNP). RESULTS: The most common clinical features were polyarthralgia (71%), haematological manifestations (65%), malar rash (54%), and nephritis (51%), respectively. All patients had positive ANA (100%), while anti-dsDNA frequency was 83%. The most common anti-ENA antibodies were anti-RNP (41%), anti-Sm (31%), anti-SSA (27%), and anti-SSB (20%), respectively. Anti-RNP had a clinical association with oral ulcer, Raynaud' phenomena, haematological, neuropsychiatric and thromboembolic manifestations. Meanwhile, anti-Sm had a significant association with serositis, mucocutaneous, constitutional, and neuropsychiatric manifestations. Anti-SSA was associated with mucocutaneous, musculoskeletal, Raynaud' phenomena, renal, haematological and cardiac manifestations, while anti-SSB was significantly associated with malar rash, serositis, thromboembolic, musculoskeletal, and neuropsychiatric manifestations. Concerning SLEADI score, anti-dsDNA antibody was significantly associated with moderate disease activity score (p=0.032) while anti-SSA significantly associated with high disease activity (p=0.045). Both anti-SSB and anti-Sm were significantly associated with both moderate and high disease activities, meanwhile anti-U1-RNP was associated with moderate disease activity (p=0.014). CONCLUSION: Anti-dsDNA and anti-ENAs antibodies were frequently found in JSLE patients (83%, 63%), respectively. They were significantly associated with variable clinical manifestations and could be used as predictors for assessment of disease activity.
RESUMO
OBJECTIVE: Lupus nephritis (LN) is closely associated with hyperuricemia, and uric acid is considered a risk factor for renal involvement in systemic lupus erythematosus (SLE). This study aimed to examine the association between serum uric acid (SUA) level and LN development and progression in SLE patients with normal renal function. METHODS: A total of 60 SLE patients with normal renal function from Ain Shams University Hospital were selected and assigned to group 1 (30 patients with LN) and group 2 (30 patients without LN). All patients were subjected to history taking, clinical examination, disease activity assessment based on SLE disease activity index (SLEDAI) and renal SLEDAI (SLEDAI-R) scores, and laboratory investigations, including as SUA, complete blood count, blood urea nitrogen (BUN), serum creatinine, creatinine clearance, urine analysis, protein/creatinine ratio, 24-h urinary protein excretion, Antinuclear antibodies (ANA), anti-dsDNA antibody, and serum complement (C3, C4). RESULTS: Disease duration, SLEDAI score, and SUA level were higher in group 1 than in group 2 (p < 0.001). SUA level was positively correlated with SLEDAI and SLEDAI-R scores, proteinuria, urinary casts, renal biopsy class, disease activity and chronicity indices, BUN level, and serum creatinine level but was negatively correlated with creatinine clearance (p < 0.05). SUA was a predictor of LN development in SLE patients (sensitivity, 83.3%; specificity, 70%). CONCLUSION: SUA is associated with the development of lupus nephritis in patients with normal kidney function also SUA in-dependently correlated with disease activity and chronicity in LN.

The growing geriatric population is facing numerous economic challenges and oral health changes. This study explores the relationship between affordability of dental care and untreated root caries among older American adults, and whether that relationship is independent of ethnicity and socioeconomic factors. Data from 1776 adults (65 years or older) who participated in the National Health and Nutrition Examination Survey (NHANES) were analyzed. The association between affordability of dental care and untreated root caries was assessed using logistic regression models. Findings indicated that untreated root caries occurred in 42.5% of those who could not afford dental care, and 14% of those who could afford dental care. Inability to afford dental care remained a statistically significant predictor of untreated root caries in the fully adjusted regression model (odds ratio 2.79, 95% confidence interval: 1.78, 4.39). Other statistically significant predictors were gender (male), infrequent dental visits, and current smoking. The study concludes that the inability to afford dental care was the strongest predictor of untreated root caries among older Americans. The findings highlight the problems with access to and use of much needed dental services by older adults. Policy reform should facilitate access to oral healthcare by providing an alternative coverage for dental care, or by alleviating the financial barrier imposed on older adults.

OBJECTIVE: The aim of this study was to objectively quantify the topographic relation of the mandibular canals, impacted third molars, and cortical plates using cone beam computed tomography (CBCT). STUDY DESIGN: A retrospective chart review was conducted using the database of a university-based imaging service. Two calibrated reviewers examined the CBCT images of 100 cases scheduled for mandibular third molar removal. They characterized the position and condition of the mandibular canal and measured its dimensions at 3 different points relative to the third molars. RESULTS: The mandibular canal is more often located buccal to the third molars but is more likely to be compressed when in a lingual position. The vertical (cephalocaudal) dimensions of the mandibular canal change significantly as the canal progresses toward the ramus. The horizontal (buccolingual) dimensions of the mandibular canal fluctuate very little but significantly narrow in proximity to the third molars. Thinning of the lingual cortical plate is common, whereas grooving of molar roots is uncommon. CONCLUSIONS: Minor variations in the horizontal dimensions of the mandibular canal close to the third molars signify an effect on the canal. This effect may indicate an increased risk of neurovascular injury. The mandibular canal can have a direct or indirect effect on the cortical plates.

Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin. These nodules are formed by the deposition of lamellar bone and are characterized by osteocytes in the core and osteoclasts around the periphery. Interpretation of osteoma cutis cases has always been challenging especially using conventional two-dimensional (2D) radiographs, owing to difficulty in localization. Cone beam CT (CBCT), with its three-dimensional (3D) capabilities, offers a great tool to help detect and diagnose these calcific entities. We report a case of miliary type OC incidentally detected in the maxillofacial region using CBCT imaging.
RESUMO
To our knowledge, the imaging features of costochondral grafts (CCGs) on cone-beam computed tomography (CBCT) have not been documented in the literature. We present the case of a CCG in the facial soft tissue to the anterior mandible, with changes mimicking a cartilaginous neoplasm. This is the first report to describe the CBCT imaging features of a long-standing graft in the anterior mandible. Implants or grafts may be incidental findings on radiographic images made for unrelated purposes. Although most are well-defined and radiographically homogeneous, being of relatively inert non-biological material, immune reactions to some grafts may stimulate alterations in the appearance of surrounding tissues. Biological implants may undergo growth and differentiation, causing their appearance to mimic neoplastic lesions. We present the case of a cosmetic autogenous CCG that posed a diagnostic challenge both radiographically and histopathologically.
