Nd:YAG/Er:YAG dual laser compared with topical steroid to treat vulvar lichen sclerosus: A randomised controlled trial.

OBJECTIVE: To evaluate the efficacy and safety of a novel non-ablative Nd:YAG/Er:YAG dual laser treatment for vulvar lichen sclerosus (LS) in comparison with the recommended first-line therapy with topical steroid. DESIGN: A randomised investigator-initiated active-controlled trial. SETTING: Single tertiary referral centre. POPULATION: Women with vulvar LS. METHODS: Randomisation (2:1) to Nd:YAG/Er:YAG laser therapy or topical clobetasol proprionate therapy. Four laser treatments at 0, 1, 2 and 4 months or decreasing doses of steroid for 6 months. MAIN OUTCOME MEASURES: The primary outcome was the change in objective validated clinical LS score in the laser arm between baseline and 6 months. Secondary outcomes were laser tolerability/safety, symptom scores and patient satisfaction. RESULTS: Sixty-six women were included, 44 in the laser group and 22 in the steroid group. The total LS score decreased by -2.34 ± 1.20 (95% CI -2.71 to -1.98) in women treated with laser compared with a decrease of -0.95 ± 0.90 (95% CI -1.35 to -0.56) in those receiving steroid applications (p < 0.001). Laser treatment was safe and well tolerated. Subjective severity scores (on visual analogue scale) and vulvovaginal symptoms questionnaire scores improved similarly for the laser and steroid arms without significant differences between the two treatments. Patient satisfaction was higher in the laser arm than in the steroid arm (p = 0.035). CONCLUSIONS: Non-ablative dual Nd:YAG/Er:YAG laser therapy was safe and significantly improved clinical outcome and subjective symptoms at the 6-month follow up. This suggests that laser may be a promising alternative to corticosteroid therapy. However, the authors caution regular follow ups because of the premalignant nature of the disease.

Efficacy of steroid therapy for improving native liver survival after pediatric acute liver failure with immune activation.

AIM: Recent evidence suggests that acute liver failure (ALF) in some patients may reflect a dysregulated immune response, and that corticosteroids improve survival of the native liver in ALF patients with high serum alanine aminotransferase levels, which are an indication of liver inflammation. However, it is unclear whether steroids are effective for pediatric acute liver failure (PALF). The aim of this retrospective case-control study is to examine whether steroid therapy for PALF accompanied by immune activation improves the survival of native liver and to identify factors that predict responses to steroid treatment. METHODS: Of 38 patients with PALF treated at Kyoto University Hospital from February 2006 to August 2022, 19 receiving steroids who met the specific criteria for identifying the pathophysiology of immune activity in the liver (the "Steroid group"), and seven steroid-free patients who also met the criteria ("Nonsteroid group") were enrolled. Patients in the "Steroid group" were categorized as "responders" or "nonresponders" according to treatment outcome. Clinical and histological data were analyzed. RESULTS: Survival of the native liver in the Steroid group was significantly higher than that in the Nonsteroid group (68% vs. 0%, respectively; p = 0.0052). Nonresponders were significantly younger, with higher Model for End-stage Liver Disease and pediatric end-stage liver disease scores, higher prothrombin time - international normalized ratio, and higher serum ferritin levels than responders. Massive hepatic necrosis was more common in nonresponders. CONCLUSION: Steroid therapy is effective for PALF patients with liver inflammation; however, liver transplantation should be prioritized for young children with ALF accompanied by severe coagulopathy or massive hepatic necrosis.

Steroid therapy in acute exacerbation of fibrotic interstitial lung disease.

BACKGROUND AND OBJECTIVE: Evidence for the benefit of steroid therapy in acute exacerbations (AEs) of idiopathic pulmonary fibrosis (IPF) is limited; however, they remain a cornerstone of management in other fibrotic interstitial lung diseases. This retrospective observational study assesses the effect of steroid treatment on in-hospital mortality in patients with acute exacerbation of fibrotic interstitial lung disease (AE-FILD) including IPF and non-IPF ILDs. METHODS: AE-FILD cases over a 10-year period were filtered using a code-based algorithm followed by individual case evaluation. Binary logistic regression analysis was used to assess the relationship between corticosteroid treatment (defined as ≥0.5 mg/kg/day of prednisolone-equivalent for ≥3 days within the first 72 h of admission) and in-hospital mortality or need for lung transplantation. Secondary outcomes included readmission, overall survival, requirement for domiciliary oxygen and rehabilitation. RESULTS: Across two centres a total of 107 AE-FILD subjects were included, of which 46 patients (43%) received acute steroid treatment. The steroid cohort was of younger age with fewer comorbidities but had higher oxygen requirements. Pre-admission FVC and DLCO, distribution of diagnoses and smoking history were similar. The mean steroid treatment dose was 4.59 mg/kg/day. Steroid use appeared to be associated with increased risk of inpatient mortality or transplantation (OR 4.11; 95% CI 1.00-16.83; p = 0.049). In the steroid group, there appeared to be a reduced risk of all-cause mortality in non-IPF patients (HR 0.21; 95% CI 0.04-0.96; p = 0.04) compared to their IPF counterparts. Median survival was reduced in the steroid group (221 vs. 520.5 days) with increased risk of all-cause mortality (HR 3.25; 95% CI 1.56-6.77; p < 0.01). CONCLUSION: In this two-centre retrospective study of 107 patients, AE-FILD demonstrates a high risk of mortality, at a level similar to that seen for AE-IPF, despite steroid treatment. Clinicians should consider other precipitating factors for exacerbations and use steroids judiciously. Further prospective trials are needed to determine the role of corticosteroids in AE-FILD.

Bronchiolitis 2021-2022 epidemic: multicentric analysis of the characteristics and treatment approach in 214 children from different areas in Italy.

Bronchiolitis causes a remarkable number of hospitalizations; its epidemiology follows that of respiratory syncytial virus (RSV), its main pathogen. The aim of this study was to evaluate the presenting features, treatment approach, and impact of medical therapy in four pediatric hospitals in Italy. Data on infants < 24 months of age hospitalized with bronchiolitis in the 2021-2022 season were collected. Between October 2021 and February 2022, 214 children were admitted. Median hospital stay was 5 days; none of the patients died. The distribution of the presenting features is largely comparable in the 33 (15.8%) RSV-negative versus the 176 (84.2%) RSV-positive children; also, no difference was observed in medical therapy provided: duration of oxygen therapy, administration of steroid, and duration of hospital stay. Systemic steroids, inhalation, or antibiotic therapy were given to 34.6%, 79.4%, and 49.1% of children respectively. Of the 214 patients with bronchiolitis, only 19 (8.8%) were admitted to ICU.   Conclusion: Our data suggest that, irrespective of treatments provided, RSV-positive and RSV-negative children had a similar clinical course. The results of our retrospective study further underline the need to improve adherence to existing guidelines on bronchiolitis treatment. What is Known: • Bronchiolitis is a common diseases with seasonal peak. The outcome is usually favorable but hospitalization and even ICU admission is not exceptional. What is New: • Children with RSV associated bronchiolitis do not have a different course and outcome. The analysis of the 2021-2022 cohort, following COVID pandemic peaking, did not show a different course and outcome. • Adherence to literature recommendation, i.e. to focus on oxygen and hydration therapy while avoiding unnecessary systemic therapy with steroid and antibiotics, should be improved.

A retrospective study of pulse steroid therapy for acute respiratory failure associated with tuberculosis.

BACKGROUND: Tuberculosis can cause acute respiratory failure, which is associated with a high mortality rate, even in patients receiving effective anti-tuberculosis therapy. We retrospectively analyzed patients with acute respiratory failure associated with tuberculosis who underwent pulse steroid therapy to describe the clinical characteristics and effectiveness of pulse steroid therapy in this condition. METHODS: The medical records of patients admitted to our hospital for culture-proven tuberculosis treatment from April 1, 2017, to March 31, 2022, who received pulse steroid therapy for acute respiratory failure associated with tuberculosis were reviewed. RESULTS: In total, 10 patients were included in this study. Chest computed tomography (CT) revealed diffuse ground-glass opacities and consolidation in these patients. Overall, 70% of the patients (7/10) showed an adjudicated response to pulse steroid therapy, with improved respiratory condition and radiological findings. Three patients died without response to pulse steroid therapy. One patient died of pancreatic cancer after recovering from respiratory failure. The remaining six patients were discharged without supplemental oxygen and completed anti-tuberculosis therapy. CONCLUSIONS: Pulse steroid therapy can lead to dramatic improvements in some patients with acute respiratory failure associated with tuberculosis.

Surgical management and outcome of primary intracranial Rosai-Dorfman disease: a single-institute experience and pooled analysis of individual patient data.

Primary intracranial Rosai-Dorfman disease (PIRDD) is considered a nonmalignant nonneoplastic entity, and the outcome is unclear due to its rarity. The study aimed to elaborate the clinic-radiological features, treatment strategies, and progression-free survival (PFS) in patients with PIRDD. Patients with pathologically confirmed PIRDD in our institute were reviewed. Literature of PIRDD, updated until December 2019, was systematically searched in 7 databases (Embase, PubMed, Cochrane database, Web of Science, Wanfang Data Knowledge Service Platform, the VIP Chinese Science and Technology Periodical Database (VIP), and the China National Knowledge Infrastructure (CNKI)). These prior publication data were processed and used according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Clinical-radiological characteristics and adverse factors for PFS were evaluated in the pooled cohort. The pooled cohort of 124 cases (81 male and 43 female), with a mean age of 39.7 years, included 11 cases from our cohort and 113 cases from 80 prior studies. Twenty-nine patients (23.4%) had multiple lesions. Seventy-four patients (59.7%) experienced gross total resection (GTR), 50 patients (40.3%) had non-GTR, 15 patients (12.1%) received postoperative adjuvant radiation, and 23 patients (18.5%) received postoperative steroids. A multivariate Cox regression revealed that GTR (HR = 4.52; 95% CI 1.21-16.86; p = 0.025) significantly improved PFS, and multiple lesions (p = 0.060) tended to increase the hazard of recurrence. Neither radiation (p = 0.258) nor steroids (p = 0.386) were associated with PFS. The overall PFS at 3, 5, and 10 years in the pooled cohort was 88.4%, 79.4%, and 70.6%, respectively. The PFS at 5 and 10 years in patients with GTR was 85.4% and 85.4%, respectively, which was 71.5% and 35.8%, respectively, in patients without GTR. Gross total resection significantly improved PFS and was recommended for PIRDD. Radiation and steroids were sometimes empirically administered for residual, multiple, or recurrent PIRDD, but the effectiveness remained arguable and required further investigation.Systematic review registration number: CRD42020151294.

Steroid responsive encephalopathy associated with autoimmune thyroiditis as a cause of acuteencephalopathy.

Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT), known as Hashimoto's encephalopathy (HE), represents a heterogeneous group of neurological and neuropsychiatric symptoms associated with a presence of antithyroid antibodies in case of other causes of encephalopathy were excluded. Clinical symptoms most commonly includes acute onset of encephalopathy, behaviour changes and cognitive dysfunction, epileptic seizures as well as cerebellar and extrapyramidal symptoms. Corticoids provides rapid and sustained therapeutic benefit in most patients and only a few patients require other immunosuppressive therapy such as plasmapheresis, intravenous immunoglobulins, or others. We present the cases of two patients with acute onset of encephalopathy, status epilepticus based on SREAT, with rapid improvement after steroid treatment.

Evaluation of steroid therapy in COVID-19 patients; in the right dose at the right time to the right patients.

Background: Although there is still no universally accepted treatment agent, steroids have been administered chronologically at every dose and at every stage of the COVID-19 pandemic. Aim: We aimed to evaluate the clinical efficacy of high-dose steroid therapy and its effect on mortality in COVID-19 patients with severe pneumonia, severe Acute Respiratory Distress Syndrome (ARDS), and septic shock. Patients and Methods: : Patients with severe pneumonia, septic shock, and ARDS due to COVID-19 who were followed up in the intensive care unit were retrospectively reviewed. Results: The study population was divided into two groups; the methylprednisolone pulse group (MP) (n = 55) and the dexamethasone group (Dex) (n = 39). When the values before and after treatment were compared; there was a statistically significant increase in the neutrophil/lymphocyte ratio after treatment in the MP group (p = 0.006). Although it was not statistically significant in the MP group, There was a numerical increase in D-dimer levels (p = 0.28). Thromboembolic complications developed in 2 patients in the MP group. The mortality outcomes of the groups were statistically similar (p = 0.943). Conclusion: We recommend steroids use in the condition that it is indicated in the critically ill group with the poor general condition. Since there is no significant difference between high-dose pulse steroid treatment and standard treatment doses, we think that the risk of complications should not be taken into account and high doses should not be used.

Coronavirus Disease 2019-Associated Mucormycosis: Risk Factors and Mechanisms of Disease.

The severe surge of coronavirus disease 2019 (COVID-19) cases on the Indian subcontinent in early 2021 was marked by an unusually high number of COVID-19-associated mucormycosis (CAM) cases reported during this same period. This is significantly higher than predicted based on available data about prevalence and risk factors for this condition. This may be due to an unusual alignment of multiple risk factors for this condition. There is high background prevalence of mucormycosis in India likely from a high prevalence of risk factors, including undiagnosed or poorly controlled diabetes. COVID-19-induced immune dysregulation and immune suppression from steroid therapy increase the risk. The role of environmental exposure is unclear. System factors such as lack of access to healthcare during a pandemic may result in delayed diagnosis or suboptimal management with potentially poor outcomes. Here, we review currently identified risk factors and pathogenesis of CAM in a pandemic surge.

Impact of severe acute respiratory syndrome coronavirus-2 infection on the outcome of primary central nervous system lymphoma treatment: A study of the International PCNSL Collaborative Group.

To optimise management of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection identifying high-risk patients and maintaining treatment dose intensity is an important issue in patients with aggressive lymphomas. In the present study, we report on the presentation, management, and outcome of an international series of 91 patients with primary central nervous system lymphoma and SARS-CoV-2 infection. SARS-CoV-2 was diagnosed before/during first-line treatment in 64 patients, during follow-up in 21, and during salvage therapy in six. Among the 64 patients infected before/during first-line chemotherapy, 38 (59%) developed pneumonia and 26 (41%) did not clear the virus. Prolonged exposure to steroids before viral infection and/or treatment with high-dose cytarabine favoured pneumonia development and virus persistence and were associated with poorer survival; 81% of patients who did not clear virus died early from coronavirus disease 2019 (COVID-19). Vaccination was associated with lower pneumonia incidence and in-hospital mortality. Chemotherapy was initiated/resumed in 43 (67%) patients, more commonly among patients who did not develop pneumonia, cleared the virus, or did not receive steroids during infection. Chemotherapy resumption in patients with viral persistence should be indicated cautiously as it was associated with a poorer survival (6-month, 70% and 87%, p = 0.07). None of the 21 patients infected during follow-up died from COVID-19, requiring similar measures as infected subjects in the general population.

Short Stature in Patients with Diamond-Blackfan Anemia: A Cross-Sectional Study.

OBJECTIVE: To systematically describe the short stature of patients with Diamond-Blackfan anemia and to explore factors affecting the height development of patients with Diamond-Blackfan anemia. STUDY DESIGN: This cross-sectional study was conducted at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, and the height, weight, and clinical data of 129 patients with Diamond-Blackfan anemia were collected from June 2020 to September 2020. RESULTS: The median height-age-z score (HAZ) of children affected by Diamond-Blackfan anemia was -1.54 (-6.36-1.96). Short stature was found in 37.98% of the patients. Specific Diamond-Blackfan anemia growth curves were developed for weight, height, and body mass index, separately for male and female patients. Multivariable logistic regression models showed that female sex (aOR 4.92; 95% CI 1.29-18.71; P = .0195), underweight (aOR 10.41, 95% CI 1.41-76.98, P = .0217), cardiovascular malformations (aOR 216.65; 95% CI 3.29-14279.79; P = .0118), and RPL11(aOR 29.14; 95% CI 1.18-719.10; P = .0392) or RPS26 (aOR 53.49; 95% CI 1.40-2044.30; P = .0323) mutations were independent risk factors for short stature. In the subgroup of patients who were steroid-dependent, patients with a duration of steroid therapy over 2 years (OR 2.95; 95% CI 1.00-8.66; P = .0494) or maintenance dose of prednisone >0.1 mg/kg per day (OR 3.30; 95% CI 1.02-10.72; P = .0470) had a higher incidence of short stature. CONCLUSIONS: Patients with Diamond-Blackfan anemia had a high prevalence of short stature. The risk of short stature increased with age and was associated with sex, underweight, congenital malformations, and RPL11 or RPS26 mutations. The duration of steroid therapy and maintenance dose of steroid was significantly associated with the incidence of short stature in steroid-dependent patients with Diamond-Blackfan anemia.

A Clinical Response-Adjusted Steroid Treatment Protocol for Children With Newly Diagnosed Idiopathic Nephrotic Syndrome.

RATIONALE & OBJECTIVE: Prednisone protocols for children with idiopathic nephrotic syndrome (INS) are generally similar in dose and duration, despite wide variations in time to response. We assessed the feasibility of a novel clinical treatment protocol characterized by a shorter duration and lower cumulative dose for children with early clinical response. STUDY DESIGN: Nonrandomized pilot clinical trial. SETTING & PARTICIPANTS: The study population included 59 children with newly diagnosed INS treated between 2014 and 2019 who responded to treatment within 8 days. INTERVENTION: The intervention group (n = 27) was treated with a response-adjusted protocol during which responders received an 8-week course of tapering doses of prednisone. The usual care group (n =32) was treated with the standard protocol (prednisone, 60 mg/m2/24 hours for 6 weeks, followed by 40 mg/m2/48 hours for 4 weeks, followed by a slow taper for a total of 24 weeks). OUTCOME: Consent rate, cumulative prednisone dose, the development of frequently relapsing or steroid-dependent nephrotic syndrome (FRNS or SDNS, respectively), relapses per year, treatment with steroid-sparing therapies, and adverse effects of steroid therapy over 3 years of follow-up observation. RESULTS: The consent rate was 88%. The mean cumulative steroid dose for the initial treatment was 70 mg/kg and 141 mg/kg (P < 0.001) in the intervention and usual care groups, respectively. None of the patients in the intervention group relapsed while on faster steroid taper down. The occurrence of FRNS and SDNS in the intervention group was not statistically different than in the usual care group, hazard ratios were 0.80 (95% CI, 0.37-1.73) and 0.61 (95% CI, 0.30-1.27), respectively. The proportions of relapse-free patients were similar (P = 0.5), and adverse steroid events did not differ between the groups. LIMITATIONS: Lack of randomization and small sample size. CONCLUSIONS: These findings demonstrate the feasibility of a shortened duration of steroid dosing for INS when patients demonstrate an initial clinical response to treatment. A larger study is needed to characterize the relative efficacy and toxicity of this novel treatment regimen. FUNDING: This study received no funding. TRIAL REGISTRATION: Registered at ClinicalTrials.gov with study number NCTO2649413.

Long-term outcomes of refractory esophageal strictures after endoscopic submucosal dissection of superficial esophageal neoplasms.

BACKGROUND: Many studies have focused on prophylactic therapy for post-endoscopic submucosal dissection (ESD) of esophageal strictures. However, various strategies cannot prevent the occurrence of postoperative strictures after extensive ESD. Postoperative strictures often inevitably occur, and endoscopic dilation is still a temporarily effective therapy. METHODS: This study included patients with post-ESD refractory esophageal strictures (RESs) from January 2014 to November 2019. Clinical effectiveness was assessed using univariate analysis and multivariate logistic regression. Hierarchical linear models were used to identify factors that predicted the dysphagia-free period. RESULTS: A total of 50 patients fulfilled the inclusion criteria and entered the study. Twenty-seven (54%) patients had a history of prophylactic oral steroid therapy. Forty-six patients (92%) underwent ≥ 75% circumferential resection, including 32 (64%) cases involving entire circumferential ESD. The mean dysphagia-free period of 50 patients was 2.9 months (95% CI 2.3-3.5). The dysphagia-free period had a linear growth trend over time, increasing by 6.9 days per endoscopic therapy, and the estimated last dysphagia-free period was 85.9 days. Old and female patients had shorter dysphagia-free periods compared with young and male patients. Endoscopic therapy success was achieved in 30 (60%) patients. Multivariate analysis revealed that circumferential lesions (OR 6.106, 95% CI 1.013-36.785, P = 0.048) were significant predictive factors for poor clinical outcome. CONCLUSION: Endoscopic dilation seemed effective in patients with post-ESD RESs by increasing the dysphagia-free period. After approximately 10 continuous dilations, 60% of patients achieved endoscopic success, and the remission rate of obstruction was increased. Prophylactic oral steroid therapy could reduce the occurrence of RESs. However, once a RES had occurred, prophylactic steroid therapy could not reduce the frequency of dilations or change the long-term outcomes. TRIAL REGISTRATION: This study was prospectively registered and approved by the Ethics Committee of West China Hospital of Sichuan University (IRB number: ChiCTR-ONN-17012382) on 2015.

Clinical outcome of neurological patients with COVID-19: the impact of healthcare organization improvement between waves.

OBJECTIVE: The aim of this study is to evaluate the differences in clinical presentations and the impact of healthcare organization on outcomes of neurological COVID-19 patients admitted during the first and second pandemic waves. METHODS: In this single-center cohort study, we included all patients with SARS-CoV-2 infection admitted to a Neuro-COVID Unit. Demographic, clinical, and laboratory data were compared between patients admitted during the first and second waves of the COVID-19 pandemic. RESULTS: Two hundred twenty-three patients were included, of whom 112 and 111 were hospitalized during the first and second pandemic waves, respectively. Patients admitted during the second wave were younger and exhibited pulmonary COVID-19 severity, resulting in less oxygen support (n = 41, 36.9% vs n = 79, 70.5%, p < 0.001) and lower mortality rates (14.4% vs 31.3%, p = 0.004). The different healthcare strategies and early steroid treatment emerged as significant predictors of mortality independently from age, pre-morbid conditions and COVID-19 severity in Cox regression analyses. CONCLUSIONS: Differences in healthcare strategies during the second phase of the COVID-19 pandemic probably explain the differences in clinical outcomes independently of disease severity, underlying the importance of standardized early management of neurological patients with SARS-CoV-2 infection.

Combination of Hyperbaric Oxygen Therapy and Oral Steroids for the Treatment of Sudden Sensorineural Hearing Loss: Early or Late?

Background and Objectives: Several treatments are available for sudden sensorineural hearing loss (SSNHL), but no studies have compared the different treatments based on the delay from the onset of the disease. Our study aims to compare the effect of hyperbaric oxygen therapy (HBOT), oral steroids (OS) and combination of both therapies (HBOT + OS) for treating SSNHL. Materials and Methods: This randomized study analyzed 171 patients with SSNHL. Patients were evaluated by pure tone audiometry test (PTA) at baseline (T0) and 20 days after treatment (T1). Three groups were available HBOT-A-, OS-B- and HBOT + OS-C-. After baseline PTA, patients were randomly assigned to each group. Statistical analysis was performed by one-way ANOVA and Chi-square. Results: Patients in the HBOT + OS and HBOT groups improved their auditory function (p < 0.05). HBOT was the best choice for treatment when started by 7 days from SSNHL onset, while HBOT + OS in case of late treatment. Profound SNHL recovered equally by HBOT and HBOT + OS (p < 0.05). Upsloping SNHL obtained better auditory results by HBOT compared to HBOT + OS (p < 0.05). Downsloping and flat SSNHL had the most improvement with HBOT + OS compared to HBOT only (p < 0.05). Conclusions: Combination of HBOT and OS is a valid treatment for SSNHL both in case of early and late treatment. Combination of HBOT and OS was the choice with the best results in case of treatment started >14 days from symptom onset.

Keratitis-ichthyosis-deafness Syndrome with Heterozygous p.D50N in the GJB2 Gene in Two Serbian Adult Patients.

Purpose: Keratitis-ichthyosis-deafness (KID) syndrome is a rare congenital ectodermal dysplastic syndrome presenting with keratitis, ichthyosis and sensorineural hearing loss. The most common causes of KID syndrome are heterozygous missense mutations in the GJB2 gene that codes for connexin 26. Case report: During the ophthalmological examination, two adult females complained of recent worsening of visual acuity in both eyes. Anamnesis revealed that their eyes were red and irritated from early childhood onwards. Both of them had thickening and keratinisation of eyelid margins, lash loss, diffuse opacification of cornea and conjunctiva caused by keratinisation of eye surface, superficial and deep corneal vascularisation and corneal oedema. Partial sensorineural hearing loss and difficulties in speech were also noted along with typical ichthyosiform erythroderma. Genetic testing of the GJB2 gene revealed a heterozygous p.D50N mutation in both patients.Patients were treated with a combined topical corticosteroid and artificial tears therapy, with steroid therapy being intensified during the last month. The therapy increased the visual acuity by decreasing corneal oedema and by forming a more regular air-tear interface during the six months follow up. Subsequently, the disease progressed despite the continuation of the therapy. Conclusion: This is the first report of Serbian patients with KID syndrome. Despite the administration of the combined topical corticosteroid and artificial tears therapy the disease is relentlessly progressive and therapeutic success of ophthalmological signs with local therapeutic modalities used so far had been disappointing.

Analysis of factors correlated with spinal clinically isolated syndrome conversion to multiple sclerosis.

INTRODUCTION: The present study aims to explore the factors influencing spinal clinically isolated syndrome (CIS) conversion to multiple sclerosis (MS). MATERIAL AND METHODS: Sixty-one patients diagnosed with spinal CIS from January 2010 to November 2020 were divided into a non-progressing (CIS) group with 27 patients, and a conversion to MS (MS) group with 34 patients, based on whether they had converted to MS. The clinical presentation at onset, the Expanded Disability Status Scale (EDSS) before and after steroid therapy, the results of magnetic resonance imaging (MRI), the oligoclonal bands in cerebrospinal fluid (CSF-OCB), and the evoked potentials (EPs) were retrospectively analysed. RESULTS: Differences in gender and age were not statistically significant between the MS and CIS groups. The median time to relapse was 12 months for the MS group, with an upper quartile of 23.7 months, and 91.2% of patients relapsed within three years. In univariate analysis, patients with CIS beginning with sensory symptoms had a lower level of progression to MS (OR = 0.311). Patients with Kurtzke Functional Systems Scores (FSSs) of pyramidal functions ≥ 2 (OR = 3.582) and positive CSF-OCB (OR = 5.208) quickly progressed to MS. There was no significant difference between the two groups in terms of spinal cord lesions < 3 vertebral segments, gadolinium enhancing lesions, or abnormal EPs. The difference in the EDSS scores before and after steroid therapy was higher in the MS group than in the CIS group (p = 0.001). Differences of ≥ 1.5 in the EDSS scores before and after steroid therapy were risk factors for CIS conversion to MS (OR = 9.333). CONCLUSIONS: Patients with spinal CIS with pure sensory abnormalities at onset were less likely to convert to MS (OR = 0.311), and the risk factors were, in order of risk, the difference in EDSS score before and after steroid therapy (≥ 1.5; OR = 9.333), positive CSF-OCB (OR = 5.208), and those with an FSS of the pyramidal functions score ≥ 2; OR = 3.582). The present study serves as a simple 'first step'. Any potential predictors identified should be validated via future prospective studies.

Long-term (16-26 years) follow-up outcome of steroid therapy in refractory autoimmune sensorineural hearing loss.

Autoimmune sensorineural hearing loss (ASHL) is a rare disease of uncertain etiology, with no established treatment strategy. The duration of morbidity is increased in refractory cases; and therefore, the preservation of hearing and the prevention of adverse effects with steroid therapy are serious long term issues to consider. Long-term follow up of patients treated for ASHL was performed retrospectively in order to elucidate the pathogenesis of ASHL, evaluate the consequences of steroid therapy, and determine a promising treatment course. The cohort in this study consists of four female patients with refractory ASHL that were followed for 16-26 years. Three patients already had profound deafness on one side, probably due to ASHL, before the initiation of steroid treatment. ASHL was managed with steroid administration and the hearing was evaluated through regular audiometric tests (173-212 times). The relationship between pure tone threshold average and steroid dose was reviewed over a long-term follow-up period for each patient. During follow-up, hearing deficit progressed rapidly several times in all patients, as did responsiveness to steroid therapy. Long-term high-dose steroid therapy was not required for hearing maintenance. Hearing thresholds were nearly maintained in three patients during the 16- to 21- year follow-up, and gradually declined over a 26-year follow-up period in one patient. Considering the progress due to presbycusis, the maintenance of hearing was considered sufficient in all patients. No serious adverse effects were observed in any of the patients. Management of patients affected by ASHL with regular audiometry allowed for hearing maintenance without the morbidity of prolonged steroid therapy. The current observations give insight into the pathogenesis of ASHL pathogenesis and establish an efficient course of treatment.

Prognosis and recurrence in cardiac sarcoidosis: Serial assessment of BMIPP SPECT and FDG-PET.

BACKGROUND: We analyzed 18F-Fludeoxyglucose positron emission tomography (FDG-PET) and 123I-betamethyl-p-iodophenyl-pentadecanoic acid (BMIPP) single-photon emission computed tomography (SPECT) performed for cardiac sarcoidosis (CS) patients taking prednisolone, identified recurrence by FDG-PET, and investigated BMIPP as a recurrence and prognostic factor in CS. METHODS AND RESULTS: CS patients who underwent BMIPP and FDG-PET within 2 months were enrolled. The recurrence-free group included patients with standardized uptake value (SUVmax) < 4 in the myocardium consecutively for ≥ 2 years. The total BMIPP SPECT defect score (BDS) was used to estimate myocardial damage. The predictability of the initial BDS and SUVmax for major adverse cardiac events (MACE) was analyzed using Kaplan-Meier analysis. Overall, 73 patients and 250 BMIPP and FDG-PET sets were analyzed retrospectively (mean follow-up, 3.5 years). The BDS was significantly greater for the recurrence group (N = 21) vs recurrence-free group (20 ± 13 vs 14 ± 12, P = 0.041). Patients with BDS ≥16 had a significantly higher MACE rate than patients with BDS < 16 (log-rank test, P = 0.016). However, MACE occurrence was comparable between patients with SUVmax ≥ 4 and < 4. CONCLUSIONS: BDS is a predictive marker of recurrence and MACE. SUV is not related to MACE. Recurrence, defined by prednisolone treatment-induced SUV variability, was observed in approximately 30% of CS patients.

Therapeutic approach with squaric acid dibutylester for steroid resistant-alopecia areata incognita: A pilot study of a single center.

Topical immunotherapy is widely used in the treatment of alopecia areata (AA). Alopecia areata incognita (AAI) is a relatively common disorder, predominantly affecting females, characterized by widespread hair thinning in the absence of typical alopecic patches. AAI can have a chronic relapsing course and in some cases can be resistant to current standard treatments. Topical immunotherapy has been used in the management of AA with encouraging results, but to date there are no literature studies reporting the efficacy of topical immunotherapy with squaric acid dibutylester (SADBE) in AAI. The aim of our study is to evaluate the efficacy and tolerance of topical immunotherapy with SADBE in AAI not responding to conventional steroid therapy. A total of 12 patients were enrolled in our Hair Disease Outpatient Service, with a proved histological diagnosis of AAI, and resistant to classical steroid therapy. Each patient underwent global photography, pull test, and trichoscopy at beginning and during the follow-ups. The efficacy of topical immunotherapy with SADBE was assessed by evaluating the changes of clinical and trichoscopic signs. Complete regrowth was achieved in 66.7% of cases (8/12), three patients remained unchanged on clinical evaluation but showed subclinical improvement on trichoscopy, whereas one patient progressed and worsened both on clinical and trichoscopic examination. All patients reported scalp diffuse mild erythema and itching the day after the application of SADBE, which were well tolerated. Three patients developed reactive cervical lymphoadenomegaly. No other side effects were observed. Topical immunotherapy with SADBE is widely used in the management of patchy AA and can be considered an effective alternative in resistant AAI, providing visible clinical and trichoscopic improvement in the majority of cases. Further studies are warranted to confirm and validate our findings.
