Decreased Serum Tryptophan and Severe Ulcerative Damage of Colon Mucosa Identify Inflammatory Bowel Disease Patients With High Risk of Cytomegalovirus Colitis.

Patients with inflammatory bowel disease (IBD) are predisposed to the reactivation of viral infections such as cytomegalovirus (CMV). Clinical discrimination of disease flares and colonic CMV reactivation is difficult in patients with established diagnosis of IBD, and there are no reliable noninvasive diagnostic tools yet. Furthermore, the influence of novel therapeutics including biologicals and Janus kinase inhibitors on the risk of CMV colitis is unclear. The goal of this study was to identify risk factors and clinical determinants of CMV colitis that could serve as minimally invasive markers both for active CMV colitis and relapse. To this end, a retrospective analysis of 376 patients with suspected or confirmed CMV colitis 2016-2023 was performed. Previous administration of systemic steroids increased the odds of CMV colitis to OR 4.6. Biologicals did not change the incidence of CMV colitis but decreased the OR of a relapse to 0.13. Clinical parameters such as severely bloody diarrhea, intense microscopic ulcerative damage, and decreased serum tryptophan correlated with detection of CMV. Importantly, persistent decrease of tryptophan was observed in patients with CMV relapse. Furthermore, tryptophan degradation through the kynurenine pathway was increased in CMV-positive patients. Taken together, we identify decreased serum tryptophan as a novel potential minimally invasive marker to aid identification of IBD patients with active CMV colitis and at high risk for relapse.

Clinical practice and outcome of patients with elderly-onset ulcerative colitis: Insights from a nationwide claims database study in Japan.

The number of older patients with ulcerative colitis is increasing; however, limited data exist regarding the differences between elderly- and non-elderly-onset ulcerative colitis. We aimed to compare the clinical practice and course of elderly-onset ulcerative colitis with those of non-elderly-onset ulcerative colitis. We selected older patients with ulcerative colitis and divided them into the elderly- and non-elderly-onset ulcerative colitis groups according to their age at onset. We compared the cumulative systemic steroid-free, molecular targeting drug-free, and surgery-free rates between the two groups. We performed a multivariate analysis to identify the clinical factors related to systemic steroid administration, the use of molecular targeting drugs, surgery, and death. We collected data of 2669 and 277 elderly and non-elderly-onset ulcerative colitis patients, respectively. The cumulative systemic steroid-free rate of elderly-onset ulcerative colitis was significantly lower than that of non-elderly-onset ulcerative colitis. However, no difference was observed in the cumulative molecular targeting drugs and surgery-free rates between the two groups. Elderly-onset ulcerative colitis significantly increased the risk of systemic steroid administration and death but not the use of molecular targeting drugs and surgery. The disease severity of ulcerative colitis and clinical practice may not differ between the elderly- and non-elderly-onset groups. However, elderly-onset ulcerative colitis was associated with increased mortality risk. Thus, we need to pay attention to the patients' condition and appropriate timing of surgery for patients with elderly-onset ulcerative colitis.

Variation in care and outcome for fragile hip fracture patients: a European multicentre study benchmarking fulfilment of established quality indicators.

Despite the availability of clinical guidelines for hip fracture patients, adherence to these guidelines is challenging, potentially resulting in suboptimal patient care. The goal of this study was (1) to evaluate and benchmark the adherence to recently established quality indicators (QIs), and (2) to study clinical outcomes, in fragile hip fracture patients from different European countries. This observational, cross-sectional multicenter study was performed in 10 hospitals from 9 European countries including data of 298 consecutive patients. A large variation both within and between hospitals were seen regarding adherence to the individual QIs. QIs with the lowest overall adherence rates were the administration of systemic steroids (5.4%) and tranexamic acid (20.1%). Indicators with the highest adherence rates (above 95%) were pre-operative (99.3%) and post-operative haemoglobin level assessment (100%). The overall median time to surgery was 22.6h (range 15.7-42.5h). The median LOS was 9.0 days (range 5.0-19.0 days). The most common complications were delirium (23.2%) and postsurgical constipation (25.2%). The present study shows large variation in the care for fragile patients with hip fractures indicating room for improvement. Therefore, hospitals should invest in benchmarking and knowledge-sharing. Large quality improvement initiatives with longitudinal follow up of both process and outcome indicators should be initiated.

The Effect of Steroid Intervention before Vitrectomy for Rhegmatogenous Retinal Detachment Associated with Choroidal Detachment: A Meta-Analysis and Systematic Review

Purpose This meta-analysis discusses the effectiveness of steroid intervention before vitrectomy in patients with rhegmatogenous retinal detachment associated with choroidal detachment. Methods We searched PubMed, MEDLINE, EMBASE, and the Cochrane Library for randomized controlled trials and observational studies published until August 2023. We included studies involving: patients with rhegmatogenous retinal detachment associated with choroidal detachment with proliferative vitreoretinopathy; an experimental group that was not administered steroids and a control group that was administered steroids; and assessment of visual acuity, retinal reattachment rate, and complications. The heterogeneity, publication bias, and sensitivity analysis were performed to ensure the statistical power and reliability of the analysis. Results Two randomized controlled trials and four case-control studies involving 490 eyes were included in the meta-analysis. There were no significant differences in the primary and final retinal reattachment rates after surgery between the steroid and non-steroid groups (primary retinal reattachment rate: odds ratio = 1.01, 95% confidence interval = 0.63–1.63, p = .41; final retinal reattachment rate: odds ratio = 0.82, 95% confidence interval = 0.43–1.59, p = .33). There was no statistically significant difference in postoperative visual acuity improvement between the two groups (odds ratio = 1.19, confidence interval = 0.63–2.25, p = .69). In addition, subgroup analyses of different types of steroids showed that systemic and local administration of steroids had similar results for retinal reattachment rate and visual acuity improvement. Conclusion Patients with rhegmatogenous retinal detachment associated with choroidal detachment who did not receive preoperative steroids achieved the same effect as patients with rhegmatogenous retinal detachment associated with choroidal detachment who did receive preoperative steroids in terms of retinal reattachment rate and visual acuity. It is recommended that patients with rhegmatogenous retinal detachment associated with choroidal detachment undergo surgery as promptly as possible.

The Role of Systemic Steroid Administration in Meniere's Syndrome: A Case Report

The Role of Systemic Steroid Administration in Meniere's Syndrome: A Case Report

Isolated Depo-Medrol Administration under Tenon's Capsule for Post-COVID-19 Uveitis in a Child: A Case Report and Literature Review.

Coronavirus disease 2019 (COVID-19) can manifest with ocular symptoms. These symptoms can be divided into isolated events attributed to COVID-19, and those occurring in multisystem inflammatory syndrome in children (MIS-C), a newly diagnosed disease entity associated with COVID-19 infection. Currently, the literature lacks specific guidelines and treatment regimens for COVID-19 ocular symptoms, especially in children. The authors present the case of a 14-and-a-half-year-old boy with bilateral uveitis of the anterior and posterior segments along with vasculitis and optic neuritis associated with SARS-CoV-2 infection. The authors also perform an up-to-date review of all available publications on the treatment of post-COVID-19 uveitis in children described in the literature between 2020 and 2023. In the case described by the authors, the treatment involved a Depo-Medrol 40 mg/mL injection uder the Tenon capsule, with two subconjunctival injections of epinephrine, topical steroid therapy and non-steroidal anti-inflammatory drugs: dexamethasone 0.1%; diclofenac eye drops. In addition, acetylsalicylic acid (150 mg) and pentoxifylline (100 mg, orally) were administered throughout the course of the disease as well as up to 12 months after its termination, until a complete improvement in visual acuity and the withdrawal of ocular lesions were achieved. It can be assumed that this type of treatment is far more beneficial for pediatric patients, with an effect comparable to systemic steroid administration with a preserved improvement in retinal-vascular circulation, without exposing the child to systemic post-steroid complications.

Outcomes of postnatal systemic corticosteroids administration in ventilated preterm newborns: a systematic review of randomized controlled trials.

Prolonged mechanical ventilation, commonly used to assist preterm newborns, increases the risk of developing bronchopulmonary dysplasia (BPD). In recent decades, studies have demonstrated that systemic corticosteroids play a significant role in the prevention and management of BPD. In this systematic review of randomized controlled trials (RCTs), we evaluated the association between the administration of systemic corticosteroids in preterm infants and its long-term outcomes, such as neurodevelopment, growth, extubation rate, and related adverse effects. We conducted an electronic search in Medline, Scopus, and PubMed using the following terms: "premature infants" and "corticosteroids." We considered all RCTs published up to June 2023 as eligible. We included all studies involving preterm newborns treated with systemic corticosteroids and excluded studies on inhaled corticosteroids. A total of 39 RCTs were evaluated. The influence of steroids administered systemically during the neonatal period on long-term neurological outcomes remains unknown, with no influence observed for long-term growth. The postnatal administration of systemic corticosteroids has been found to reduce the timing of extubation and improve respiratory outcomes. Dexamethasone appears to be more effective than hydrocortisone, despite causing a higher rate of systemic hypertension and hyperglycemia. However, in the majority of RCTs analyzed, there were no differences in the adverse effects related to postnatal corticosteroid administration. Dexamethasone administered during the neonatal period appears to be more effective than hydrocortisone in terms of respiratory outcomes; however, caution should be taken when administering dexamethasone. Data derived from current evidence, including meta-analyses, are inconclusive on the long-term effects of the administration of systemic steroids in preterm infants or the possibility of neurodevelopmental consequences.

Preterm Birth and in Utero Exposure to Corticosteroids Are Associated With Increased Infection Risk in Children of Mothers With IBD.

Corticosteroids, thiopurines, and biologics may come into play during pregnancy in women with inflammatory bowel disease and potentially impact the developing fetal immune system. We aimed to assess the risk of serious infections in children stratified by in utero exposure to biologics and immunomodulators or concomitant treatment with corticosteroids. All singleton IBD pregnancies between 2008 and 2022 at a tertiary IBD center in Denmark were included. Maternal and offspring demographics, maternal disease activity, antenatal medical treatment, and infant infections resulting in hospital admission were recorded after review of medical records. In 602 live births (99.0%), we registered exposure to antenatal treatment as follows: biological monotherapy (n = 61, 10.2%), thiopurines (n = 110, 17.9%), biologics and concomitant thiopurines (n = 63, 10.3%), and controls (ie, no treatment with biological and/or thiopurines; n = 369, 60.6%). Preterm delivery (<37 gestational weeks) and systemic steroid administration during the third trimester were associated with an increased risk of serious infection in the offspring immediately after birth (relative risk = 17.5; 95% confidence interval, 7.8-39.8; P < .001, and relative risk = 4.8; 95% confidence interval, 1.5-12.7; P = 0.003, respectively).Intra-uterine exposure to biologics or combination treatment were not associated with a statistically significant higher risk of serious infections compared with controls; however, combination treatment showed an inclination towards an increased risk across analyses. Preterm birth and systemic corticosteroid administration late in pregnancy are significant risk factors for serious infections in the offspring of IBD mothers.

Brown syndrome: a literature review.

The current data on various aspects of Brown syndrome are limited and sporadic. This review provides a coherent and comprehensive review of basic features, etiology, classification, differential diagnosis, and different management strategies of patients with Brown syndrome. In this topical review, PubMed, Scopus, and Google Scholar search engines were searched for papers, published between 1950 and January 2023 based on the keywords of this article. The related articles were collected, summarized, categorized, assessed, concluded, and presented. Brown syndrome is identified by restricted passive and active elevation of the eye in adduction. The condition is divided into congenital and acquired causes. The clinical features result from a restricted motion of the superior oblique tendon sheath through the trochlea while trying to look up in adduction. The newest explanation of the underlying pathophysiology has been explained as the presence of a fibrotic strand in the superior oblique muscle tendon with variable insertion sites which creates various elevation deficits seen in Brown syndrome. The most common clinical features include the presence of an abnormal head posture, V-pattern strabismus, and hypotropia in the primary position. Management of Brown syndrome includes watchful observation, surgical, and non-surgical procedures. Some cases might resolve spontaneously without any intervention; however, some acquired cases might require systemic and/or intra-trochlear steroid administration to treat the underlying causes. Surgical procedures such as superior oblique tenectomy and using a silicon tendon expander are indicated in the presence of hypotropia and significant abnormal head posture in the primary position.

Leflunomide for the Treatment of Immune-Mediated Uveitis in a Dog.

A 5 yr old castrated male bichon frise presented with chronic bilateral uveitis that had previously been controlled with systemic steroid administration for 6 mo, resulting in weight gain, polyuria, and polydipsia. To control the uveitis without systemic side effects, oral cyclosporine was started after discontinuing oral steroid, but discontinued one month later because of severe vomiting. Leflunomide (2 mg/kg q 12 hr) was initiated, and the uveitis symptoms resolved after 2 mo. The dose was tapered according to the remission of clinical signs, with no relapse during the following 13 mo. Leflunomide therapy was then discontinued due to vomiting caused by severe gastroenteritis and pancreatitis, and topical prednisolone monotherapy was continued . At 8 mo after discontinuation of leflunomide, bilateral uveitis recurred, and leflunomide therapy was resumed. However, the patient lost vision due to the progression of clinical signs at 33 mo after commencing leflunomide, and evisceration of the glaucomatous right eye was performed at 43 mo. Histopathologic examination revealed lymphocyte and plasma cell infiltration and melanin-laden macrophages in the uveal tissue, and the patient was diagnosed with immune-mediated uveitis. This case indicated that oral leflunomide may be a viable treatment option for canine idiopathic immune-mediated uveitis.

Successful use of dupilumab for egg-induced eosinophilic gastroenteritis with duodenal ulcer: a pediatric case report and review of literature

BackgroundNon-esophageal eosinophilic gastrointestinal disorder (non-EoE-EGID) is a rare disease in which eosinophils infiltrate parts of the gastrointestinal tract other than the esophagus; however, the number of patients with non-EoE-EGID has been increasing in recent years. Owing to its chronic course with repeated relapses, it can lead to developmental delays due to malnutrition, especially in pediatric patients. No established treatment exists for non-EoE-EGID, necessitating long-term systemic corticosteroid administration. Although the efficacy of dupilumab, an anti-IL-4/13 receptor monoclonal antibody, for eosinophilic esophagitis, has been reported, only few reports have demonstrated its efficacy in non-EoE EGIDs.Case presentationA 13-year-old boy developed non-EoE-EGID with duodenal ulcers, with chicken eggs as the trigger. He was successfully treated with an egg-free diet, proton pump inhibitors, and leukotriene receptor antagonists. However, at age 15, he developed worsening upper abdominal pain and difficulty eating. Blood analysis revealed eosinophilia; elevated erythrocyte sedimentation rate; and elevated levels of C-reactive protein, total immunoglobulin E, and thymic and activation-regulated chemokines. Upper gastrointestinal endoscopy revealed a duodenal ulcer with marked mucosal eosinophilic infiltration. Gastrointestinal symptoms persisted even after starting systemic steroids, making it difficult to reduce the steroid dose. Subcutaneous injection of dupilumab was initiated because of comorbid atopic dermatitis exacerbation. After 3 months, the gastrointestinal symptoms disappeared, and after 5 months, the duodenal ulcer disappeared and the eosinophil count decreased in the mucosa. Six months later, systemic steroids were discontinued, and the duodenal ulcer remained recurrence-free. The egg challenge test result was negative; therefore, the egg-free diet was discontinued. Blood eosinophil count and serum IL-5, IL-13, and eotaxin-3 levels decreased after dupilumab treatment. The serum levels of IL-5 and eotaxin-3 remained within normal ranges, although the blood eosinophil counts increased again after discontinuation of oral prednisolone.ConclusionsSuppression of IL-4R/IL-13R-mediated signaling by dupilumab may improve abdominal symptoms and endoscopic and histologic findings in patients with non-EoE-EGID, leading to the discontinuation of systemic steroid administration and tolerance of causative foods.

Patient Characteristics Associated with Growth of Patient-Derived Tumor Implants in Mice (Patient-Derived Xenografts).

Background: patient-derived xenografts (PDXs) have defined the field of translational cancer research in recent years, becoming one of the most-used tools in early drug development. The process of establishing cancer models in mice has turned out to be challenging, since little research focuses on evaluating which factors impact engraftment success. We sought to determine the clinical, pathological, or molecular factors which may predict better engraftment rates in PDXs. Methods: between March 2017 and January 2021, tumor samples obtained from patients with primary or metastatic cancer were implanted into athymic nude mice. A full comprehensive evaluation of baseline factors associated with the patients and patients' tumors was performed, with the goal of potentially identifying predictive markers of engraftment. We focused on clinical (patient factors) pathological (patients' tumor samples) and molecular (patients' tumor samples) characteristics, analyzed either by immunohistochemistry (IHC) or next-generation sequencing (NGS), which were associated with the likelihood of final engraftment, as well as with tumor growth rates in xenografts. Results: a total of 585 tumor samples were collected and implanted. Twenty-one failed to engraft, due to lack of malignant cells. Of 564 tumor-positive samples, 187 (33.2%) grew at time of analysis. The study was able to find correlation and predictive value for engraftment for the following: the use of systemic antibiotics by the patient within 2 weeks of sampling (38.1% (72/189) antibiotics- group vs. 30.7% (115/375) no-antibiotics) (p = 0.048), and the administration of systemic steroids to the patients within 2 weeks of sampling (41.5% (34/48) steroids vs. 31.7% (153/329), no-steroids) (p = 0.049). Regarding patient's baseline tests, we found certain markers could help predict final engraftment success: for lactate dehydrogenase (LDH) levels, 34.1% (140/411) of tumors derived from patients with baseline blood LDH levels above the upper limit of normality (ULN) achieved growth, against 30.7% (47/153) with normal LDH (p = 0.047). Histological tumor characteristics, such as grade of differentiation, were also correlated. Grade 1: 25.4% (47/187), grade 2: 34.8% (65/187) and grade 3: 40.1% (75/187) tumors achieved successful growth (p = 0.043), suggesting the higher the grade, the higher the likelihood of success. Similarly, higher ki67 levels were also correlated with better engraftment rates: low (Ki67 < 15%): 8.9% (9/45) achieved growth vs. high (Ki67 ≥ 15%): 31% (35/113) (p: 0.002). Other markers of aggressiveness such as the presence of lymphovascular invasion in tumor sample of origin was also predictive: 42.2% (97/230) with lymphovascular vs. 26.9% (90/334) of samples with no invasion (p = 0.0001). From the molecular standpoint, mismatch-repair-deficient (MMRd) tumors showed better engraftment rates: 62.1% (18/29) achieved growth vs. 40.8% (75/184) of proficient tumors (p = 0.026). A total of 84 PDX were breast models, among which 57.9% (11/19) ER-negative models grew, vs. 15.4% (10/65) of ER-positive models (p = 0.0001), also consonant with ER-negative tumors being more aggressive. BRAFmut cancers are more likely to achieve engraftment during the development of PDX models. Lastly, tumor growth rates during first passages can help establish a cutoff point for the decision-making process during PDX development, since the higher the tumor grades, the higher the likelihood of success. Conclusions: tumors with higher grade and Ki67 protein expression, lymphovascular and/or perineural invasion, with dMMR and are negative for ER expression have a higher probability of achieving growth in the process of PDX development. The use of steroids and/or antibiotics in the patient prior to sampling can also impact the likelihood of success in PDX development. Lastly, establishing a cutoff point for tumor growth rates could guide the decision-making process during PDX development.

Magnetic resonance imaging screening forosteonecrosis ofthe femoral head after coronavirus disease 2019.

Systemic steroid administration has been suggested for the treatment of coronavirus disease 2019 (COVID-19), but the occurrence of osteonecrosis of the femoral head (ONFH) was one of the concerns for this treatment. This study aimed to use magnetic resonance imaging (MRI) to assess the incidence of ONFH after the treatment for COVID-19. The study included 41 patients who were hospitalized and treated for pneumonia or other COVID-19-induced diseases. We conducted interviews with these patients regarding hip pain and performed MRI screenings for ONFH. The incidence and timing of ONFH after COVID-19 treatment were investigated. Of the 41 patients, one died of pneumonia and the remaining patients did not complain of hip pain. MRI screening was performed for 26 patients, and asymptomatic ONFH was detected in one patient (3.8%) whose ONFH appeared 1 month after the COVID-19 infection. Our MRI screening of ONFH in post-COVID-19 patients revealed asymptomatic ONFH, which would not have been identified without active screening. Physicians should be aware that ONFH may occur in patients after treating COVID-19.

Postauricular versus systemic use of steroids for sudden hearing loss: A systematic review and meta-analysis of randomized controlled trials.

Sudden sensorineural hearing loss (SSNHL) can be debilitating and is one of the most common otological diseases. Steroids play an important role in its treatment. There are many ways to administer steroids, and the efficacy and safety of different administration routes remain unclear. This meta-analysis aimed to investigate the effect and safety of different types of steroid delivery administration for the treatment of SSNHL. We searched the Weipu, Wanfang, Chinese Biomedical Literature, National Knowledge Infrastructure, Web of Science, Embase and PubMed databases for randomized controlled trials (RCTs) on glucocorticoid treatments for SSNHL to compare the efficacy of postauricular injection and systemic steroid administration. Review Manager 5.4 software was used for data synthesis, which included the recovery rate (RR) of reported hearing improvement and change level in pure-tone audiometry (PTA). Subgroup analyses were performed based on different drugs, basic treatment, initial PTA, drug administration methods, onset time, and treatment course. Stata 15.1 software was used for analyses of publication bias and sensitivity. Our meta-analysis included 38 studies involving 3609 patients with SSNHL. In all included studies, the risk difference (RD) using reported improvement as an outcome measure was 0.12 for postauricular injection administration compared with systemic therapy (95% confidence interval [CI] = 0.008, 0.16, P < .00001, I2 = 59%). When examining PTA changes as an outcome measure (19 studies), the mean difference was 6.06 (95% CI = 3.96, 8.16, P < .00001, I2 = 70%). The RD for hearing improvement was compared among different factors, and the results showed that postauricular injection is superior to systemic steroid administration. Postauricular injection may be safer and more effective treatment than systemic therapy as a treatment for SSNHL.

Targeting Epithelium Dysfunction and Impaired Nasal Biofilms to Treat Immunological, Functional, and Structural Abnormalities of Chronic Rhinosinusitis.

Chronic rhinosinusitis (CRS) with (CRSwNP) or without (CRSsNP) nasal polyps is a prevalent and heterogeneous disorder existing as a spectrum of clinical conditions with complex underlying pathomechanisms. CRS comprises a broad syndrome characterized by multiple immunological features involving complex interactions between the genes, the microbiome, host- and microbiota-derived exosomes, the epithelial barrier, and environmental and micromilieu exposures. The main pathophysiological feature is an epithelial barrier disruption, accompanied by microbiome alterations and unpredictable and multifactorial immunologic overreactions. Extrinsic pathogens and irritants interact with multiple epithelial receptors, which show distinct expression patterns, activate numerous signaling pathways, and lead to diverse antipathogen responses. CRSsNP is mainly characterized by fibrosis and mild inflammation and is often associated with Th1 or Th17 immunological profiles. CRSwNP appears to be associated with moderate or severe type 2 (T2) or Th2 eosinophilic inflammation. The diagnosis is based on clinical, endoscopic, and imaging findings. Possible CRS biomarkers from the peripheral blood, nasal secretions, tissue biopsies, and nasally exhaled air are studied to subgroup different CRS endotypes. The primary goal of CRS management is to maintain clinical control by nasal douching with isotonic or hypertonic saline solutions, administration of nasal and systemic steroids, antibiotics, biologic agents, or, in persistent and more severe cases, appropriate surgical procedures.

AB1660 ASSOCIATION OF COMMON COMORBIDITIES WITH ASEPTIC OSTEONECROSIS: EXPERIENCE OF RHEUMATOLOGY DEPARTMENT

BackgroundOsteonecrosis (ON) (avascular necrosis, aseptic necrosis or subchondral avascular necrosis) is not a specific disease entity but the final common pathway of a number of conditions leading to bone death [1].ObjectivesTo examine the frequency of ON and to investigate different common comorbidities association with ON in a rheumatology department.MethodsAll patients with a first-time hospital diagnosis of ON in rheumatology department during 1995–2022 were included. We obtained a complete hospital history of comorbidities preceding the diagnosis of ON.Results43 ON cases were included with an average of 1.6 cases/year. The mean age of our patients was 53 years (27-82). The sex-ratio male to female was 1,75 (12 females and 21 males).The different sites of osteonecrosis were distributed as follows: femoral head, femoral condyle, semilunar and humeral head.The diagnosis of ON was confirmed by simple radiography in15 cases, bone scan in 14 cases and with magnetic resonance imagery in 14 cases.Dyslipidemia was the most common comorbidity (13.9 % of patients), followed by high blood pressure, hypothyroidism, allergic asthma, obesity, alcohol abuse, renal failure, rheumatoid arthritis, diabetes, gout, hemopathy, trauma, and coronary artery disease.Among these chronic conditions, the most common recognized risk factor of ON in our series was medications (corticosteroids) followed by dyslipidemia, alcohol abuse, hemopathy (sickle cell anemia, Hodgkin’s lymphoma and beta thalassemia) and trauma (fractures and dislocation of the hip).All patients received medical treatment based on painkillers and functional rehabilitation.12 patients had surgical treatment: 8 total hip prosthesis, 3 Core decompression and bone marrow aspirate concentrate injection for Avascular Necrosis of the femoral head and 1 Proximal row carpectomy for semilunar osteonecrosis.ConclusionThis monocentric study provides evidence for an increasing ON incidence associated to systemic steroid administration. Hence the need for early and adequate management of this factor to prevent possible complications such as aseptic osteonecrosis.Reference[1]Pavelka K. Osteonecrosis. Baillieres Best Pract Res Clin Rheumatol. 2000 Jun;14(2):399-414. doi: 10.1053/berh.2000.0072. PMID: 10925752.Acknowledgements:NIL.Disclosure of InterestsNone Declared.

Acute kidney injury and chronic kidney disease in umbilical cord blood transplant recipients.

Acute kidney injury (AKI) is a frequent early complication post hematopoietic stem cell transplant (HSCT), associated with high morbidity and mortality. Cord blood transplant (CBT) recipients are potentially exposed to more nephrotoxic insults, compared to patients undergoing HSCT from other donor sources. We aimed to identify risk factors for AKI in patients undergoing CBT. We also aimed to identify the impact of AKI on chronic kidney disease (CKD) and survival outcomes by one-year post-CBT. Adults and children who underwent a first CBT at our Institution were retrospectively evaluated. AKI was staged according to Kidney Disease Improving Global Outcomes (KDIGO) definitions. Cox regression models were used to estimate the association of demographic factors and post-CBT parameters with the cause-specific hazard of AKI. We identified 276 patients. Median age was 32 years, 28% (77/276) were children (<18 years) and 129 (47%) were white. A myeloablative conditioning regimen was administered to 243 patients (88%) and 248 (90%) received cyclosporine for GVHD prophylaxis. One-hundred and eighty-six patients (67%) developed AKI by day 60 post-transplant, with 72 (26%) developing severe AKI (stage 2 and 3). In a multivariable analysis, each increase in bilirubin level of 1 mg/dL was associated with a 23% increase in the risk of severe AKI (adjusted HR 1.23, 95% CI 1.13 - 1.34, p<.0001). Conversely, systemic steroid administration appeared to be protective of severe AKI (unadjusted HR 0.36, 95% CI 0.18 - 0.72, p=.004) in a univariate model . Two-hundred-forty-seven patients were evaluable at the one-year time point. Among those, 100 patients (40%) developed CKD one-year post-CBT. Severe AKI was associated with a higher hazard of non-relapse mortality (adjusted HR=3.26, 95% CI 1.65-6.45, p=.001) and overall mortality (adjusted HR=2.28, 95% CI 1.22-4.27, p=.01). AKI is a frequent complication after CBT and is associated with worse outcomes. Questions remain as to the mechanism of the protective role of steroids on kidney function in the setting of CBT.

Relationship between Ventricular Size on Latest Ultrasonogram and the Bayley Scores ≥ 18 Months in Extremely Low Gestational Age Neonates: A Retrospective Cohort Study.

A ventricle-to-brain index (VBI) >0.35 is associated with low scores on the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) in preterm infants with birth weight <1,250 g. However, VBI obtained at the third ventricle has only moderate interobserver reliability. The objective of this study was to test (1) reliability of VBI measured at the foramen of Monro on the latest ultrasonogram (US) before discharge using the intraclass correlation coefficient (ICC) and (2) the relationship between VBI and BSID-III scores at ≥18 months corrected age. The present study is a single-center retrospective cohort study. The study included 270 preterm infants born at 230/7 to 286/7 weeks of gestational age. The ICC of VBI between independent measurements by two study radiologists on the first 50 patients was 0.934. Factors associated with the value of VBI included severe intraventricular hemorrhage, bronchopulmonary dysplasia, and systemic steroid administration for BPD but not postmenstrual age. In multivariate analysis, VBI was negatively and independently associated with cognitive (p = 0.002), language (p = 0.004), and motor (p < 0.001) BSID-III scores. The association between VBI and BSID-III scores was observed even in infants in whom the latest US was obtained before term equivalent age. The association between VBI and BSID-III scores was also observed after excluding those with severe intraventricular hemorrhage. In this very preterm cohort the measurement of VBI had excellent reliability. Moreover, VBI measurements were negatively associated with motor, language, and cognitive BSID-III scores. · Mean values of VBI are stable with postmenstrual age.. · Values at the foramen of Monro are reliable and reproducible.. · VBI is negatively associated with Bayley scores.. · The association is observed even before term age..

Adjuvant multimodal treatment for spinal intradural extramedullary capillary hemangioma with subpial growth: illustrative case.

Spinal intradural extramedullary capillary hemangiomas are rare vascular lesions. Although total resection is the first treatment, the efficacy of adjuvant therapies, such as steroid or radiation therapy, has not been investigated. A 74-year-old man presented with progressive back pain, gait disturbance, and left chest pain. Spinal magnetic resonance imaging (MRI) revealed an intradural extramedullary lesion at the middle thoracic level. Preoperatively, systemic steroid administration improved his chest pain and reduced the tumor size. The authors performed tumor extirpation. Because the tumor strongly adhered to the pia matter, in short, the tumor accompanied with partial subpial growth, subtotal resection was performed, leaving a thin layer of the tumor. A pathological examination revealed capillary hemangioma. His gait disturbance showed rapid improvement. Stereotactic cyber knife treatment was performed for the residual tumor at 1 month after the operation. Serial MRI showed a gradual decrease in the tumor size and no recurrence at 2 years after the operation.
