A retrospective longitudinal study of 52 Finnish patients with X-linked retinoschisis.

To describe clinical characteristics in Finnish patients with X-linked retinoschisis (XLRS) longitudinally with emphasis on retinal morphology and genotype-phenotype correlations. A retrospective cohort study reviewed medical records from patients with genetically confirmed XLRS from the Department of Ophthalmology, Helsinki University Hospital. Best-corrected visual acuity (BCVA), refraction, colour fundus photography, spectral-domain optical coherence tomography and genetic information were collected. Fifty-two males were diagnosed at the median age of 7 years (range 1-57) and followed for a median of 8 years (range, 1-49). Baseline findings included macular retinoschisis in 92(89%), macular atrophy in 25 (24%) and peripheral retinoschisis in 22 (21%) eyes. Vitreous haemorrhage occurred in 10 (10%) eyes, more frequently with peripheral schisis (p < 0.001). Nearly half of the patients, 22 (42%) were classified as visually impaired according to WHO. Median central retinal thickness was similar between initial (355 μm) and latest visits (360 μm) (p = 0.781). Low BCVA was associated with macular atrophy (p < 0.001), ellipsoid zone disruption (p = 0.007) and peripheral retinoschisis (p = 0.006). The three Finnish founder mutations c.214G >A, c.221G >T, and c.325G >C in exon 4 of retinoschisin 1 (RS1) were identified in 40 patients (77%). No associations were found between the genotypes and phenotypes. Three-fourths of the patients carried the Finnish founder mutations in RS1, but we did not detect any genotype-phenotype association. Macular atrophy was associated with the poorest visual acuity. Ocular compilations were associated with peripheral retinoschisis, suggesting that these patients should be followed more frequently.

Reconstructive surgical therapy of peri-implant defects with ribose cross-linked collagen matrix and crosslinked hyaluronic acid – a prospective case series

ObjectiveTo investigate the efficacy of ribose-crosslinked collagen (RCLC) matrices functionalized by crosslinked hyaluronic acid (xHya) for reconstructive treatment of class I and III (b-c) peri-implantitis lesions in a transmucosal healing mode.Materials and methodsThirteen patients presenting with 15 implants were included in this prospective case series. Upon flap reflection, the implants were thoroughly decontaminated employing glycine powder air polishing and adjunctive sodium hypochlorite. For defect augmentation, xHyA was administered to the bony defect walls, exposed implant surfaces, and the RCLC matrix before defect grafting. The full-thickness flap was readapted and sutured around the implant neck for transmucosal healing. Baseline and respective values at the 12 months post-op evaluation were recorded for the clinical parameters peri-implant probing depth (PPD), buccal soft tissue dehiscence (BSTD) and bleeding on probing (BoP). Furthermore, two independent investigators analyzed radiographic changes in the defect area. The mean changes for all variables were analyzed with a paired t-test.ResultsThe initial mean PPD was 7.2 ± 1.9 mm, and BoP was present in 63% of sites. After 12 months, PPD at the latest visit was 3.2 ± 0.66 mm, which amounted to a respective 3.9 ± 1.85 mm reduction, while the BoP frequency dropped to 10% at all sites. Radiographic bone fill was accomplished for 62.8% of the former defect area, accompanied by a mean MBL gain of 1.02 mm around the treated implants (all p < 0.001).ConclusionsWithin the limits of this case series, we conclude that the proposed treatment sequence substantially improved peri-implant defects and offered a simplified but predictive technique.Clinical relevanceReconstructive treatment approaches for peri-implantitis are effective but remain non-superior to open flap debridement. Further research on novel biomaterial combinations that may improve reconstructive treatment outcomes are warranted. Ribose-crosslinked collagen matrices biofunctionalized by hyaluronic acid used in this study yield improved clinical and radiographic peri-implant conditions after 12 months.Graphical

Paracentral Acute Middle Maculopathy and Risk of Cardiovascular Disease, Stroke, and Death: A Longitudinal Study

To evaluate the risk of acute cardiovascular events (CVE), including cardiovascular diseases, cerebrovascular diseases, and all-cause mortality in patients with paracentral acute middle maculopathy (PAMM). Retrospective cohort study METHODS: We studied 43 individuals with optical coherence tomography -documented PAMM attending Moorfields Eye Hospital between January 2014 and June 2021. We excluded patients with preceding (< 2 years) major adverse cardiac events. We stratified patients by age (<50 years & ≥50 years) and whether associated with retinal vascular diseases (RVD) or isolated (iPAMM). We assessed risk factors, clinical characteristics, and visual prognosis of the patients. CVE risk was estimated using Kaplan-Meier curves, the log-rank test, and Cox proportional hazards regression. In young patients with iPAMM patients (n=12), underlying predisposing factors included six (50%) sickle cell disease and five (41.6%) others, including breakthrough bleeding in pregnancy, migraine, genetic cardiomyopathy, amphetamine use; among those with PAMM+RVD (n=12) one (9%) had a vascular disorder, and four (44.4%) oral contraceptive use. In the older group of 20 patients, 15 (75%) had at least one coronary risk factor. During a median follow-up of 14 months (range 12-54), older subjects with iPAMM had a higher risk of developing CVE than those with PAMM+RVD (p<0.001). Notably, iPAMM displayed a significantly earlier peak in peri-PAMM CVE risk compared to PAMM+RVD (median: 1 month, range 1-40 months vs. 36 months, range 12-54 months). Relative to those with PAMM+RVD, risk of CVE was significantly higher in patients with iPAMM, adjusted for age and sex (hazard ratio: 6.37, 95% Confidence Interval 1.68-24.14, p=0.017). No young patients experienced adverse CVE. At baseline, older iPAMM patients mean best corrected visual acuity of 0.7 (0-1.8) LogMAR, which improved significantly to 0.2 (0-1.30) LogMAR at the latest visit (p=0.033). Young individuals with iPAMM have a higher prevalence of predisposing factors compared to those presenting with combined PAMM+RVD. Older patients with iPAMM had a higher risk of CVE than those with PAMM+RVD, especially in the peri-onset timeframe. This suggests the need for a prompt cardiovascular assessment to rule out systemic etiologies and optimize cardiovascular risk factors, in addition to ongoing ophthalmology input.

Clinical Course of Residual Ventricular Septal Defects After Congenital Heart Disease Repair.

The clinical course of residual ventricular septal defects after congenital heart disease repair is not completely elucidated in the medical literature. This study assessed the incidence, size, and clinical course of residual defects.This single-center retrospective study included 132 patients who survived after ventricular septal defect patch closure (n = 107) and intracardiac repair of double-outlet right ventricle (n = 16) and tetralogy of Fallot (n = 9). Residual defect was evaluated on transthoracic echocardiogram upon hospital discharge and at outpatient clinic visits.The median age at surgery was 1.2 (0.3-13.9) years. In total, 45 (34.1%) patients presented with residual defects upon hospital discharge. The residual defects were within 2mm (n = 27), 2-3mm (n = 15), and > 3mm (n = 3), and the median size was 1.5 (0.5-3.8) mm. There was no late mortality during a median follow-up of 5.4years. Among 42 residual defects measuring < 3mm upon hospital discharge, 37 (82.2%) spontaneously closed. Further, five defects decreased in size (1.8 ± 0.6mm upon hospital discharge vs1.2 ± 0.8mm at the latest visits, p = 0.15). However, the size of three residual defects measuring > 3mm upon hospital discharge increased, and two patients required re-surgery for residual defect.Significant residual defect requiring reoperation was rare. In most cases, residual defects measuring < 3mm upon hospital discharge spontaneously closed within 5years, and the size of the other defects decreased.

Five-year follow-up of patients with difficult-to-treat rheumatoid arthritis.

To elucidate the long-term outcomes of patients with difficult-to-treat rheumatoid arthritis (D2T RA). We collected data on the clinical course of patients who had been identified as D2T RA in 2018 until 2023. We stratified the patients according to outcomes at the last visit: resolved D2T RA, persistent D2T RA, and mortality. We compared their clinical characteristics and investigated the predictive factors for the resolution of D2T RA or mortality. Furthermore, we investigated the impact of the causes of D2T RA identified in 2018, multidrug resistance, comorbidities, and socioeconomic factors on outcomes in 2023. Of 173 patients identified as D2T RA in 2018, 150 were included in the analysis. Among them, D2T RA was resolved in 67 (45%), 75 (50%) remained as D2T RA, and 8 (5%) died. Patients with resolved D2T RA were significantly younger at the latest visit (p= 0.02), had a higher proportion of treatment changes during five years (p= 0.002), and had a higher proportion of interleukin-6 receptor inhibitors use in 2023 (p= 0.04) than those in patients with persistent D2T RA or those who died. D2T RA resolved in 38% of patients with multidrug resistance, mainly with treatment changes. Rheumatic disease comorbidity index and glucocorticoid dose escalation were independent risk factors for mortality (odds ratio [OR], 3.50; p= 0.02 and OR, 31.9; p= 0.002, respectively). Further modifications in RA treatment are useful for resolving D2T RA. Multiple comorbidities and glucocorticoid use are associated with mortality.

Chorioretinal Atrophic Lesions Evolution in Patients with Quiescent Myopic Choroidal Neovascularization Followed for More Than 10 Years.

To evaluate the progression of chorioretinal atrophic areas associated with myopic choroidal neovascularization (CNV) in high myopic patients followed by a minimum period of 10 years. Patients with myopic CNV lesions that achieved clinical and structural remissions over 10 years of follow-up were included. Medical records were reviewed for CNV characterization and treatment, best-corrected visual acuity at baseline (BCVA0), immediately after the last treatment (BCVA1) and at the latest visit (BCVA2). Fundus autofluorescence (FAF) was used to quantify the amount of atrophic area increase per year associated with the treated myopic CNV lesion. The first FAF performed after treatment suspension (FAF1) was compared with the most recent exam (FAF2). Thirty-six eyes from 36 patients were included. Mean total follow-up was 12.38 ± 2.68 years. Mean number of intravitreal injections (IVI) was 12.50 ± 12.40 and 25% of the eyes had previous treatment with photodynamic therapy (PDT). Mean improvement between BCVA0 and BCVA1 was 5.58 ± 15.98 letters (p < 0.001). However, a drop of 8.03 ± 12.25 letters was noticed between BCVA1 and BCVA2. FAF1 was 6.34 ± 4.92mm2 and increased to 9.88 ± 7.56mm2 (3.54 ± 3.79mm2 variation p < 0.001). The mean growth rate of the atrophic area was 0.89 ± 0.84mm2 per year. BCVA2 negatively correlated with FAF2 (k = -0.498, p = 0.002) being worse in patients with higher atrophic area growth rate (k = -0.341, p = 0.042). Eyes treated with PDT needed less IVI (5.89 ± 5.21 vs 14.70 ± 13.36, p = 0.008) but had larger FAF1 (9.80 ± 5.33 vs 5.19 ± 4.27, p = 0.013) and FAF2 (16.05 ± 7.10 vs 7.83 ± 6.63, p = 0.003). Hypothyroidism was associated with higher atrophy growth rate (1.55 ± 1.15 vs 0.73 ± 0.67, p = 0.016). This research demonstrates the importance of chorioretinal atrophy progression after myopic CNV lesions regression and its impact on visual prognosis, reporting a mean yearly growth of 0.89 mm2 in atrophic areas. Previous treatment with PDT and hypothyroidism were identified as risk factors associated with larger atrophic areas and worse visual outcomes.

Optical Coherence Tomography Parameters and Optimal Cut-off Values for Predicting Visual Prognosis in Ethambutol-Induced Optic Neuropathy.

The objective of this study was to evaluate the prognostic value of optical coherence tomography (OCT) parameters in patients with ethambutol-induced optic neuropathy (EON) and establish their optimal cut-off values for predicting visual acuity outcomes. A retrospective cross-sectional study was conducted on 64 eyes of 32 patients with EON who underwent OCT. Peripapillary retinal nerve fiber layer (pRNFL) and macular ganglion cell-inner plexiform layer (mGCIPL) thickness were measured using Cirrus high-definition OCT (HD-OCT) within 3 months after EON diagnosis. Visual acuity of patients was recorded and analyzed at the first visit, the 1-year visit, and the latest visit. Prognostic capacities of OCT parameters for visual prognosis were evaluated and their optimal cut-off values for predicting final visual acuity were established. Increased pRNFL thickness was significantly associated with better visual acuity at 1 year postdiagnosis and the latest visit. A significant association was established between increased pRNFL thickness and a higher rate of recovery to visual acuity >20/25 at 1 year postdiagnosis. Receiver-operating characteristic curves identified ideal cut-off values for OCT parameters as follows: pRNFL thickness of 83 μm (sensitivity 100%, specificity 48.3%) and mGCIPL thickness of 74 μm (sensitivity 100%, specificity 83.3%) for visual acuity >20/25 at 1 year, mGCIPL thickness of 61 μm (sensitivity 85.7%, specificity 71.4%) for visual acuity >20/40 at 1 year, with corresponding AUCs exceeding 0.7. Both pRNFL and mGCIPL thickness possess potential values for predicting visual outcomes in patients with EON. Future research should continue to explore the utility of OCT parameters in EON prognosis.

The Characteristics and Outcomes of Nonhospitalized Patients With Heart Failure in Saudi Arabia: A Contemporary Single-Center Study.

Background Contemporary data on patients with heart failure (HF) in Saudi Arabia is limited. Methods This was a retrospective study of patients who were followed in the HF Clinic at our center after January 1, 2022. The study end date was August 31, 2023. Patients who were alive and followed for <6 months were excluded. We reported the clinical characteristics, utilization of established therapies for HF, proportion of potential candidates for ancillary HF treatments, and rates of HF events and mortality. Results A total of 202 patients met the study criteria. The mean age was 56.0 ± 15.2 years. The median follow-up from the initial visit to the study end date was 47 months (interquartile range {IQR}: 29-58 months). Coronary artery disease (CAD) was the cause of HF in 85 (42%) patients. At their latest visit, 103 (51%) patients had diabetes, 82 (41%) were obese, and 134 (66%) received quadruple therapy. Iron deficiency was present in 143 (71%) patients during follow-up. At their latest visit, moderate-to-severe or severe functional mitral regurgitation (MR) and hyperkalemia were present in 15 (7%) and 20 (10%) patients, respectively. The combined annual rate of HF hospitalization and emergency visits for HF was 20%. At least one hospitalization for HF within a year before the study end date occurred in 19 (9%) patients. The annual all-cause mortality was 1.8%. Conclusion This contemporary cohort of outpatients with HF was relatively young and had a high prevalence of diabetes, obesity, and iron deficiency. An estimate of potential candidates for iron replacement, transcatheter repair of the mitral valve, novel potassium binders, and the implantation of the pulmonary artery pressure monitorwas among the first reported regionally. All-cause mortality was low, yet the burden of HF-related events was significant.

12-year follow-up of the first endothelial keratoplasty without Descemet stripping in a 3-month newborn with Congenital Hereditary Endothelial Dystrophy (CHED)

BackgroundEndothelial Keratoplasty (EK) is now considered as the standard treatment for Congenital Hereditary Endothelial Dystrophy (CHED) by many surgeons. We present the 12-year clinical outcome of the youngest operated patient with CHED in which we successfully performed a bilateral EK procedure without removing the recipient endothelium-Descemet complex.Case presentationIn November 2010 we performed EK without Descemet Stripping in a 3-month female newborn, thinking that the lower manipulation obtained by leaving the recipient endothelium–Descemet complex could be the key factor for the success of our surgery. Such a particular technique was new in newborns. The surgery was a success, but the long-term visual result was not predictable at that time. We followed the patient at 4 months, and then yearly. At the latest visit in October 2022 the visual, cognitive, and motorial developments were normal, with Best-corrected Distance Visual Acuity of 0.4 LogMAR with − 0.75 D sf + 2.75 D cyl @ 105° in the right eye (RE) and 0.4 LogMAR with + 1.50 D sf + 2.50 D cyl @ 60° in the left eye (LE). The endothelial microscope showed an unexpected healthy endothelium, with a cell count of 2383 cells/mm2 in the RE and of 2547 cells/mm2 in the LE from a starting donor count of 2900 cells/mm2. No secondary procedures were performed during the 12-year follow-up.ConclusionEK without Descemet stripping has proved to be a successful procedure over time in our newborn. The unexpected healthy endothelium suggests a role of the Descemet membrane in CHED.

AI-based hip prosthesis failure prediction through evolutional radiological indices.

This study aimed to develop artificial intelligence models for predicting hip implant failure from radiological features. Analyzing the evolution of the periprosthetic bone and implant's position throughout the entire follow-up period has shown the potential to be more relevant in outcome prediction than simply considering the latest radiographic images. Thus, we investigated an AI-based model employing a small set of evolutional parameters derived from conventional radiological features to predict hip prosthesis failure. One hundred sixty-nine radiological features were annotated from historical anteroposterior and lateral radiographs for 162 total hip arthroplasty patients, 32 of which later underwent implant failure. Linear regression on each patient's chronologically sorted radiological features was employed to derive 169 corresponding evolutional parameters per image. Three sets of machine learning predictors were developed: one employing the original features (standard model), one the evolutional ones (evolutional model), and the last their union (hybrid model). Each set included a model employing all the available features (full model) and a model employing the few most predictive ones according to Gini importance (minimal model). The evolutional and hybrid predictors resulted highly effective (area under the ROC curve (AUC) of full models = 0.94), outperforming the standard one, whose AUC was only 0.82. The minimal hybrid model, employing just four features, three of which evolutional, scored an AUC of 0.95, proving even more accurate than the full one, exploiting 173 features. This tool could be shaped to be either highly specific (sensitivity: 80%, specificity: 98.6%) or highly sensitive (sensitivity: 90%, specificity: 92.4%). The proposed predictor may represent a highly sensitive screening tool for clinicians, capable to predict THA failure with an advance between a few months and more than a year through only four radiological parameters, considering either their value at the latest visit or their evolution through time.

Clinical outcomes of collagen matrix as adjuvant to open bleb revision with mitomycin C following failed trabeculectomy

ABSTRACT Introduction Trabeculectomy (TB) with mitomycin C (MMC) is a mainstay of glaucoma surgery for intraocular pressure reduction and visual field preservation, but surgical outcomes are often limited by episcleral and subconjunctival fibrosis leading to intraocular pressure (IOP) spikes. Research Design and Methods Retrospective case series presents seven eyes at a tertiary glaucoma center where open bleb needling was performed in combination with a collagen matrix implant and MMC following failed TB due to excessive fibrosis. Results Seven eyes of seven patients were included. Baseline IOP was 23.9 (±7.4) mmHg with a significant decrease on post-operative (post-op) day 1 to 4.6 mmHg. By post-op month 1, all eyes maintained a non-hypotonus IOP ≥ 5. Notably, four eyes (57%) had at least 1 unsuccessful open bleb needling without a collagen matrix implant prior. All eyes were complication-free by the latest visit without any complication-related visual decline, and six eyes (86%) were glaucoma medication-free at the most-recent post-op follow-up (12.4 ± 11.4 months). All cases were performed by one experienced glaucoma subspecialist (author DL). Conclusions Open bleb needling and MMC in combination with a collagen matrix implant may result in improved and sustained IOP control for encapsulated blebs following failed trabeculectomy, especially in those with prior unsuccessful bleb revisions.

Differences in treatment strategies for LDL-cholesterol reduction in a university lipid clinic vs. standard care apart from the use of PCSK9 inhibitors

Lipid-lowering therapy (LLT) in patients with cardiovascular disease (CVD) is insufficient despite clear guideline recommendations. Lipid clinics have specialized in patients with dyslipidemia, but the magnitude and reduction of low-density lipoprotein cholesterol (LDL-C) in lipid clinics has not yet been studied in depth. To assess LDL-C reduction in very high-risk CVD patients achieved in a lipid clinic through different forms of LLT in comparison to standard care without the initiation of PSCK9 inhibitors. Data from 96 lipid clinic patients were analyzed retrospectively and compared to 84 standard care patients. Very high-risk patients were defined according to the European Society of Cardiology (ESC). Different combinations of LLT focusing on statins and ezetimibe were investigated. Achievement of LDL-C treatment goals according to ESC guidelines as well as LDL-C reduction were assessed. Baseline and follow-up data of 180 very high-risk CVD patients (mean age 67.7 (±9.8) y; 60.6% male) were used. Achievement of the LDL-C goal in lipid clinic patients increased significantly from 14.6% at baseline to 41.7% at the latest visit (p<0.001) while standard care patients improved from 21.4% to 33.3% (p=0.08). The largest relative LDL-C reduction via an adjustment in LLT was achieved by initiation of high-intensity statins (50.8 ± 4.9%, n=5, p < 0.05). Treatment in a lipid clinic leads to a superior LDL-C goal achievement in very high-risk CVD patients as compared to standard care with the highest reduction under LLT with high-intensity statins and ezetimibe. Referral algorithms have to be established for high-risk patients.

Weight Gain and Nutritional Improvement After Magnetically Controlled Growing Rod Surgery in Early-Onset Scoliosis: A Single Centre Analysis of 68 Patients.

Early-onset scoliosis (EOS) is frequently associated with complex spine and chest wall deformities that may lead to severe cardiopulmonary impairment and malnutrition. The aim of this study is to evaluate the change in the nutritional status of EOS patients after treatment with magnetically controlled growing rod instrumentation (MCGR) in a single center. We prospectively collected data of patients treated with MCGR for EOS in a single center. Exclusion criteria were <2 years' follow-up and incomplete weight-for-age Z-scores (WAZ) data. Preoperative and postoperative WAZ, radiographic parameters, including major coronal curve, kyphosis angle, space available for lung ratios, thoracic height, and unplanned returns to the operating room (UPROR), were analyzed. SD and 95% Confidence intervals (CI) are presented with means. Sixty-eight patients (37 males/31 females) were included. The mean age at surgery was 8.2 years (SD 2.8, range 1.8-14.2), and the mean follow-up time was 3.8 years (SD 1.0, range 2.1-6.8). The study population was categorized by the primary diagnosis as follows: 23 neuromuscular, 18 idiopathic, 15 congenital, and 12 syndromic patients. The major coronal curve improved between the preoperative and latest visits by 40% ( P <0.005, SD 27, CI 33-47), while the space available for lung ratios improved by 8% ( P <0.005, SD 13, CI 5-12). Thoracic height increased by 25% ( P <0.005, SD 13, CI 22-28), and kyphosis angle decreased by 25% ( P <0.005, SD 26, CI 9-39). Eighteen patients (27%) required a total of 53 UPRORs. WAZ improved significantly between the preoperative and the latest follow-up ( P =0.005). Regression analysis showed WAZ improvements were most significant in the underweight patients and the Idiopathic or Syndromic EOS patients. UPROR was not associated with deterioration in WAZ. Treatment of EOS patients with MCGR resulted in an improvement in nutritional status, as evidenced by the significant increase in WAZ. Underweight, Idiopathic and Syndromic EOS patients, and those who required UPROR all had significant improvement in their WAZ with MCGR treatment. Therapeutic Study-Level II.

Capturing the Transition From Intermediate to Neovascular AMD: Longitudinal Inner Retinal Thinning and Factors Associated With Neuronal Loss.

To estimate the impact of transition from intermediate to exudative neovascular age-related macular degeneration (AMD) on the inner retina and to assess the relationship of clinical characteristics and optical coherence tomography (OCT) findings with inner retinal changes. A total of 80 participants (80 eyes) with intermediate AMD at baseline who developed neovascular AMD within 3 months were included in the analysis. OCT scans at follow-up visits (after transition to neovascular AMD) were compared with values at the latest visit with evidence of intermediate AMD to quantify longitudinal inner retinal changes. OCT images were also reviewed for qualitative features reflecting distress of the outer retina or retinal pigment epithelium and for the presence and characteristics of exudation. The parafoveal and perifoveal inner retinal thicknesses were 97.6 ± 12.9 µm and 103.5 ± 16.2 µm, respectively, at baseline, and a significant increase in values was detected at the visit with first evidence of neovascular AMD (parafoveal: 99.0 ± 12.8 µm, P = 0.040; perifoveal: 107.9 ± 19.0 µm, P = 0.0007). Conversely, the inner retina was significantly thinner at the 12-month follow-up visit after initiation of the anti-vascular endothelial growth factor therapy (parafoveal: 90.3 ± 14.8 µm, P < 0.0001; perifoveal: 92.0 ± 21.3 µm, P < 0.0001). At the 12-month follow-up visit, OCT evidence of alterations of the external limiting membrane and history of previous intraretinal fluid were associated with a greater inner retinal thinning. The development of exudative neovascularization is associated with significant neuronal loss that may be detected once the exudation is resolved. OCT analysis demonstrated a significant relationship between morphological alterations detected using structural OCT and the amount of inner neuronal loss.

Differences in periodontal parameters between SPT patients who regularly and irregularly visited the dental clinic analyzed at tooth level: a 14-year retrospective cohort study.

The purpose of this study was to evaluate the periodontal status of patients who routinely did SPT, when compared to patients that did not SPT. This retrospective cohort study was conducted at a general dental office from 2001 to 2019. Patients aged 18 to 81years who visited the dental office over a 10-year period were assigned into two groups: an SPT group, which included patients who continually visited the dental office for SPT one or more times every year, and an irregular group, consisting of patients who did not visit the dental office at least once a year. A total of 7307 teeth (SPT group) and 4659 teeth (irregular group) were evaluated, and the periodontal conditions were compared between the first and latest visits. Multiple regression analysis was used to analyze the results. The mean follow-up time was 13.74years. The risk factors for improvements in probing pocket depth included age, sex, smoking, diabetes mellitus, molar tooth, and irregular SPT group (p < 0.001), and that for a positive bleeding on probing site was the irregular group (odds ratio 2.94; 95% confidence interval 2.63-3.29). This study showed that lack of routine in attending the SPT program significantly decreased the periodontal parameters, thus highlighting the importance of continuing with the program to maintain the periodontal health.

Erysipelas-Like Erythema: A Manifestation of Severe Disease Phenotype in Pediatric Patients with Familial Mediterranean Fever.

Erysipelas-like erythema is the pathognomonic skin manifestation of familial Mediterranean fever although not frequently seen in the pediatric population. This study aims to describe the differences between patients presenting with and without erysipelas-like erythema and to examine the relation of erysipelas-like erythema with subclinical inflammation in a large pediatric cohort of familial Mediterranean fever patients. This retrospective study from a single pediatric rheumatology referral center included familial Mediterranean fever patients with a follow-up for at least 6 months in the last 5 years. Patients were grouped according to the presence of erysipelas-like erythema and subclinical inflammation. Among 515 patients with familial Mediterranean fever, 35 patients (6.8%) were found to present with erysipelas-like erythema, and the earliest age for erysipelas-like erythema was 2.9 years. All erysipelas-like erythema lesions were defined on lower extremities with concurrent arthritis in 21 patients (60.0%). Compared to other patients in the cohort, patients presented with erysipelas-like erythema had significantly higher frequencies of acute arthritis, subclinical inflammation, and biallelic exon 10 mutations, and they used significantly higher doses of colchicine at the latest visits (all P ≤ .002). Patients with subclinical inflammation more frequently presented with erysipelas-like erythema compared to others without subclinical inflammation (21.7% vs. 2.9%, P &lt; .001). Erysipelas-like erythema is an uncommon but important finding that can be a sign of severe disease course and subclinical inflammation in the pediatric population with familial Mediterranean fever.

Contribution of coronal vertebral and IVD wedging to Cobb angle changes in adolescent idiopathic scoliosis during growth

Study designProspective studyBackgroundVertebral and intervertebral disc (IVD) wedging are often seen in patients with adolescent idiopathic scoliosis (AIS). However, the relationship between wedging and curve progression, and the change of wedging before bracing to final weaning is unknown. The aim of this study was to investigate the pattern and sequence of vertebral and IVD wedging development, and to determine the relationship between the change of wedging and curve progression in AIS during growth.MethodsThis was a prospective study of 32 AIS females with right-sided thoracic curves and/or left-sided lumbar curves who completed brace treatment. They were classified into progression and non-progression groups. Vertebral and IVD wedging were calculated for each spinal segment. The wedging pattern was first identified and then used to determine the sequence of wedging development. Percentage change in the sum of wedging during growth was calculated and compared.ResultsThe sum of vertebral wedging for both groups was 2.4° to 8.7° more than that of IVD wedging in the thoracic spine but 8.7° to 17.7° less in the lumbar spine. Out of the 20 curves assessed, 5 thoracic curves and 1 lumbar curve developed vertebral wedging before IVD wedging, and 3 thoracic curves and 4 lumbar curves had the opposite pattern. The progression group had larger increases in sum of vertebral (40%) and IVD (28.6%) wedging as compared to the non-progression group (both 16.7%). A significant difference in wedging between the first and the latest visits was found in the progression group only (p < 0.05).ConclusionPattern and sequence of vertebral and IVD wedging were related to the location of the curve rather than the presence of curve progression. Progressed curves were associated with increased wedging during growth.Level of evidenceII

Characteristics of Optic Neuritis in South Korean Children and Adolescents: A Retrospective Multicenter Study.

Purpose To analyze the clinical characteristics and prognosis of optic neuritis (ON) in pediatric patients aged <19 years in South Korea. Methods This multicenter retrospective cohort study included 127 pediatric patients (median age: 10.3 (IQR: 7.3–14.2) years; female, 62.2%) who experienced ON for the first time between January 2004 and January 2018, with data obtained from five tertiary university-based hospitals in Korea. When ON was bilateral, the worse eye was selected for analysis. The baseline clinical characteristics and prognoses of patients, as well as the associations between these parameters, were analyzed. Results The baseline clinical characteristics of the patients were as follows: best-corrected visual acuity (BCVA) < 20/200, 65.9%; pain on eye movement, 47.2%; optic disc swelling, 66.9%; and bilateral involvement, 41.7%. Among 101 patients who were followed up for ≥6 months, 48 (47.5%), 12 (11.9%), 19 (18.8%), 13 (12.9%), and 9 (8.9%) had been diagnosed with isolated ON, recurrent ON, multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and acute disseminated encephalomyelitis (ADEM)-related ON, respectively. At the latest visit, 81.9% and 71.1% had achieved BCVA of ≥20/40 and ≥ 20/25, respectively. Only disc swelling at presentation was associated with poor baseline BCVA (coefficient: 0.31, P=0.004) and greater improvement in BCVA (coefficient: 0.49, P = 0.001P=0.001); there were no significant associations between the baseline factors and final BCVA. Conclusions This study demonstrated pediatric ON-related clinical characteristics and visual outcomes in South Korea. Within this cohort, in about 40.6% of patients, ON was associated with other demyelinating diseases, namely, MS, NMOSD, and ADEM.

Physical Activities and Associated Factors Among HIV/AIDS Patients: A Questionnaire Survey.

PurposeRegular physical activity is essential for maintaining health and improving people’s overall quality of life living with HIV; improving metabolic side effects associated with taking highly active antiretroviral therapy (HAART). This study investigated physical activity levels and associated factors among HIV/AIDS patients.Patients and MethodsA single-center, cross-sectional study was conducted from July to September 2021. A convenience sample of 377 HIV/AIDS patients was recruited from a medical center in Zhuhai, China. Data were collected through self-report questionnaires and patients’ medical records.ResultsThe average physical activity of HIV/AIDS patients was 1007.15±868.63 met-min/w; 53.8% of patients expressed medium-level activity, and 46.2% in low-level activity. Log-link gamma generalized linear model results showed that gender, T-CD4+ at the latest visit, self-efficacy, and perceived barriers were significant predictors of assessing physical activity levels.ConclusionNearly half of HIV/AIDS patients have low levels of physical activity. In particular, women and patients with lower CD4 cells, lower self-efficacy, and more perceived barriers had lower levels of physical activity. More knowledge is needed on the causes of physical inactivity among people with HIV, and physical activity programs need to be developed for people living with HIV in developing countries.
