AimTo evaluate Perceptual visual skills in delayed language developed children.Material and methodsThe relation between visual skills and language has not been rigorously examined in previous investigations. This is a case-control study which comprised of 25 preschool children with Delayed Language Development (DLD) (cases) and 25 typically developed children (control). Exclusion criteria: any neurological or visual impaired disorder. All children had undergone Intelligent Quotient (I.Q) using Stanford Binet (IV edition), Attention Deficit Hyperactivity disorder Test (ADHDT) and Illinois Test of Psycholinguistic Abilities (ITPA). The performance of cases was surprisingly superior to the performance of controls in all visual skills. Moreover, it was significantly different in visual closure (P value=0.027) and visual memory (P value=0.005).ConclusionReading disorders that may develop in children with DLD are more related to language than to visual skills. DLD has some strong perceptual skills such as visual closure and visual memory. This should be taken in consideration while planning a strategy for language therapy.

Helicobacter pylori infection and extragastric diseases in 2017
Abstract
The huge variety of extragastric diseases linked to Helicobacter pylori infection is widely known, and new studies are conducted every year on this topic. Neurological disorders and metabolic syndrome are some of the main issues debated in the most recent literature. Articles on the association of H. pylori with skin diseases, inflammatory bowel diseases, immunologic impairment, kidney dysfunction, allergic asthma, and respiratory diseases have been published as well. In this perspective, eradication therapy for this infection could become a mandatory measure in prevention strategy.

Genomics of Helicobacter pylori
Abstract
As Helicobacter pylori infects half the world's population and displays an extensive intraspecies diversity, genomics is a powerful tool to understand evolution and disease, to identify factors that confer higher risk of severe sequelae, and to find new approaches for therapy both among bacterial and host targets. In line with these objectives, this review article summarizes the major findings in Helicobacter genomics in papers published between April 2016 and March 2017.

Gastric cancer: Basic aspects
Abstract
Gastric cancer is one of the most incident and deadliest malignancies in the world. Gastric cancer is a heterogeneous disease and the end point of a long and multistep process, which results from the stepwise accumulation of numerous (epi)genetic alterations, leading to dysregulation of oncogenic and tumor suppressor pathways. Gastric cancer stem cells have emerged as fundamental players in cancer development and as contributors to gastric cancer heterogeneity. For this special issue, we will report last year's update on the gastric cancer molecular classification, and in particular address the gastric cancer groups who could benefit from immune checkpoint therapy. We will also review the latest advances on gastric cancer stem cells, their properties as gastric cancer markers and therapeutic targets, and associated signaling pathways. The understanding of the molecular basis underlying gastric cancer heterogeneity and of the role played by gastric cancer stem cells in cancer development and heterogeneity is of major significance, not only for identifying novel targets for cancer prevention and treatment, but also for clinical management and patient stratification for targeted therapies.

Other Helicobacters, gastric and gut microbiota
Abstract
The current article is a review of the most important and relevant literature published in 2016 and early 2017 on non-Helicobacter pylori Helicobacter infections in humans and animals, as well as interactions between H. pylori and the microbiota of the stomach and other organs. Some putative new Helicobacter species were identified in sea otters, wild boars, dogs, and mice. Many cases of Helicobacter fennelliae and Helicobacter cinaedi infection have been reported in humans, mostly in immunocompromised patients. Mouse models have been used frequently as a model to investigate human Helicobacter infection, although some studies have investigated the pathogenesis of Helicobacters in their natural host, as was the case for Helicobacter suis infection in pigs. Our understanding of both the gastric and gut microbiome has made progress and, in addition, interactions between H. pylori and the microbiome were demonstrated to go beyond the stomach. Some new approaches of preventing Helicobacter infection or its related pathologies were investigated and, in this respect, the probiotic properties of Saccharomyces, Lactobacillus and Bifidobacterium spp. were confirmed.

Diagnosis of Helicobacter pylori infection
Abstract
Important progress is being made in endoscopic methods which allow clinicians to predict the presence of Helicobacter pylori based on characteristics of gastric mucosa and to obtain targeted biopsies. There are also important developments in molecular methods with various techniques derived from standard PCR, applied both on gastric biopsies and stool specimens. Progress is being made in microfluidic systems to get a reliable diagnosis in a very short time. The interest of the 13C urea breath test has been confirmed as well as stool antigen tests. Attempts are being made to find biological markers of premalignant conditions by serology, other than pepsinogens.

Helicobacter: Inflammation, immunology and vaccines
Abstract
Helicobacter pylori is usually acquired in early childhood and the infection persists lifelong without causing symptoms. In a small of cases, the infection leads to gastric or duodenal ulcer disease, or gastric cancer. Why disease occurs in these individuals remains unclear, however the host response is known to play a very important part. Understanding the mechanisms involved in maintaining control over the immune and inflammatory response is therefore extremely important. Vaccines against H. pylori have remained elusive but are desperately needed for the prevention of gastric carcinogenesis. This review focuses on research findings which may prove useful in the development of prognostic tests for gastric cancer development, therapeutic agents to control immunopathology, and effective vaccines.

Pathogenesis of Helicobacter pylori infection
Abstract
Helicobacter pylori is responsible for the most commonly found infection in the world's population. It is the major risk factor for gastric cancer development. Numerous studies published over the last year provide new insights into the strategies employed by H. pylori to adapt to the extreme acidic conditions of the gastric environment, to establish persistent infection and to deregulate host functions, leading to gastric pathogenesis and cancer. In this review, we report recent data on the mechanisms involved in chemotaxis, on the essential role of nickel in acid resistance and gastric colonization, on the importance of adhesins and Hop proteins and on the role of CagPAI-components and CagA. Among the host functions, a special focus has been made on the escape from immune response, the ability of bacteria to induce genetic instability and modulate telomeres, the mechanism of autophagy and the deregulation of micro RNAs.

Treatment of Helicobacter pylori infection 2017
Abstract
This review summarizes important studies regarding Helicobacter pylori therapy published from April 2016 to April 2017. The main themes that emerge involve studies assessing the efficacy of bismuth and nonbismuth quadruple regimens. While in recent years, much of the emphasis on the use of bismuth has focussed on its utility in a second-line setting, an increasing number of studies this year have shown excellent efficacy in first-line therapy. The efficacy of bismuth as a second-line after sequential and concomitant therapy was particularly noteworthy. Antibiotic resistance was more intensely studied this year than for a long time, and definite trends are presented regarding an increase in resistance, including the fact that clarithromycin resistance in particular is now at a level where the continued use of clarithromycin triple therapy first-line as a mainstream treatment is not recommended. Another exciting trend to emerge this year is the utility of vonoprazan as an alternative to PPI therapy, especially in resistant and difficult-to-treat groups.

Epidemiology of Helicobacter pylori infection
Abstract
The study of Helicobacter pylori genetic variability brought us interesting data on the history of mankind. Based on multilocus sequence typing and more recently on whole-genome sequencing, paleomicrobiology still attracts the attention of global researchers in relation to its ancestor roots and coexistence with humans. Three studies determining the prevalence of virulence factors illustrates the controversial results obtained since 30 years by studies trying to associate prevalence of different virulence markers and clinical outcomes of H. pylori infection. Three articles analyzed the prevalence and risk of multiple (genetically distinct isolates) and mixed (susceptible and resistant isolates) infections. A number of studies confirm that H. pylori prevalence is falling worldwide especially in the developed world and in children but that the level of infection is higher in certain ethnic minorities and in Migrants. There is little new in identifying the mode of H. pylori transmission though intrafamilial spread appears to be important. There have, however, been some interesting papers on the presence of the organism in food, water, and the oral cavity.

Helicobacter pylori, gastric cancer and other gastrointestinal malignancies
Abstract
In a retrospective study performed in California, U.S.A., ca. 3% of patients with gastric intestinal metaplasia (GIM) developed gastric cancer (GC) within a median time period of 4.6 years after diagnosis of GIM. This observation stresses the importance of targeted surveillance even in regions with a low GC prevalence. Patients with alcoholic liver disease as well as survivors of colorectal and lobular breast cancer were found to be at increased risk of secondary GC. A population-based Chinese study confirmed "serologic biopsy" as a useful screening tool for stratifying the individual risk of developing GC. Concerning GC therapy, a post hoc analysis of the MAGIC trial reported that regression of lymph node metastases, but not the tumor regression itself, predicts overall survival. Furthermore, in patients with high microsatellite instable tumors, perioperative chemotherapy leads to an increased risk of mortality. Two studies confirmed that eradication therapy is worthwhile as an initial treatment for gastric mucosa-associated lymphoid tissue (MALT) lymphoma irrespective of the H. pylori infection status and stage. An increased risk of a second primary malignancy including GC was observed in these patients treated with immuno/chemotherapy but not in patients treated solely with an H. pylori eradication treatment. With respect to gastrointestinal malignancies other than GC, discrepant data have been published regarding the association of H. pylori with pancreatic cancer whereas no association has been reported with esophageal squamous cell carcinoma. The majority of published studies still support an association of H. pylori with colon neoplasms.

Helicobacter pylori infection in children
Abstract
Helicobacter pylori infection in children differs from that in adults, from the point of view of epidemiology, host response, clinical features, related diseases, and diagnosis, as well as treatment strategies.
The prevalence of H. pylori infection, in both children and adults, is decreasing in the Western World as well as in some developing countries, which contrasts with the increase in childhood asthma and allergic diseases. Recurrent abdominal pain is not specific during H. pylori infection in children. The role of H. pylori infection and failure to thrive, children's growth, type I diabetes mellitus (T1DM) and celiac disease remains controversial.
The main initial diagnosis is based on upper digestive endoscopy with biopsy-based methods. Nodular gastritis may be a pathognomonic endoscopic finding of childhood H. pylori infection. The infection eradication control is based on validated noninvasive tests.
The main cause of treatment failure of H. pylori infection is its clarithromycin resistance. We recommend standard antibiotic susceptibility testing of H. pylori in pediatric patients prior to the initiation of eradication therapy. H. pylori treatment in children should be based on an evaluation of the rate of eradication in the local population, a systematic use of a treatment adapted to the susceptibility profile and a treatment compliance greater than 90%. The last meta-analysis in children did not show an advantage for sequential therapy when compared to a 14-day triple therapy.
Finally, the high rate of antibiotic resistance responsible for therapy failure in recent years justifies the necessity of a novel vaccine to prevent H. pylori infection in children.

Helicobacter pylori infection and nonmalignant diseases
Abstract
A substantial decrease in Helicobacter pylori-associated peptic ulcer disease has been observed during the last decades. Drug-related ulcers as well as idiopathic ulcers are becoming predominant and are more refractory to treatment; however, H. pylori infection still plays an important role in ulcer bleeding and recurrence after therapy. The effect of H. pylori eradication upon functional dyspepsia symptoms has been reviewed in this article and generally confirms the results of previous meta-analyses. Additional evidence suggests a lack of impact upon the quality of life, in spite of improvement in symptoms. The association of H. pylori with gastroesophageal reflux disease and Barrett's esophagus remains controversial with a majority of published studies showing a negative association. Furthermore, a strong inverse relationship between the presence of H. pylori and the esophageal eosinophilia was also reported. Several studies and a review addressed the role of H. pylori in autoimmune gastritis and pernicious anemia. The association of the above still remains controversial. Finally, the necessity of routine endoscopy and H. pylori eradication before bariatric surgery is discussed. Several studies suggest the rationale of preoperative upper endoscopy and H. pylori eradication prior to surgery. However, the prevalence of H. pylori infection prior to surgery in these studies generally reflects the overall prevalence of the infection in the particular geographic area. In addition, results on the role of H. pylori in developing postoperative complications remain controversial.

The new targeted therapy in systemic lupus erythematosus: Is the glass half-full or half-empty?
Source:Autoimmunity Reviews
Author(s): Andrea Doria, Ricard Cervera, Mariele Gatto, Gamal Chehab, Matthias Schneider
Biologic therapy is still limited in lupus, where chronic steroid exposure and wide-spectrum immunosuppression are major triggers of organ damage.In this viewpoint, the authors summarize their views for a "half-full or half-empty" glass on targeted therapy in SLE.The are several reasons for seeing the glass half-empty and in this section the authors propose a critical reflection on scarceness of novel targeted lupus therapies. They show how hard it is to identify suitable biological and clinical targets and to choose the patients that may best fit those targets, as well as to stratify patients according to disease subtype and response, all contributing to the final outcome.On the other hand, reasons are emerging to see the glass half-full, including the growing evidence that disease activity and damage can both be hindered by the proper use of novel drugs and that promising molecules are upcoming. In this section, the authors contextualize potentials and failures of new drugs, providing a critical reading of disappointing results and underlining the concrete benefits obtainable through a wise use of available treatments.Indeed, combining medications with new therapeutic strategies such as the treat-to-target seems the right approach to add some water to a filling glass.

Author(s): S. Sciascia, E. Coloma-Bazán, M. Radin, M.L. Bertolaccini, C. López-Pedrera, Gerard Espinosa, P.L. Meroni, R. Cervera, M.J. Cuadrado
The current mainstay of treatment in patients with thrombotic antiphospholipid syndrome (APS) is long-term anticoagulation, mainly with Vitamin K antagonist agents. Some recently available studies have created new ground for discussion about the possible discontinuation of anticoagulation therapy in patients with a history of thrombotic APS in whom antiphospholipid antibodies (aPL) are not detected any longer (i.e. aPL seroconversion).We report the main points discussed at the last CORA Meeting regarding the issue whether or not anticoagulation can be stopped after aPL seroconversion. In particular, we systematically reviewed the available evidence investigating the clinical outcome of APS patients with aPL seroconversion in whom anticoagulation was stopped when compared to those in whom therapy was continued regardless the aPL profile. Furthermore, the molecular basis for the aPL pathogenicity, the available evidence of non-criteria aPL and their association with thrombosis are addressed.To date, available evidence is still limited to support the indication to stop oral anticoagulation therapy in patients with a previous diagnosis of thrombotic APS who subsequently developed a negative aPL profile. The identification of the whole risk profile for cardiovascular manifestations and possibly of a second level aPL testing in selected patients with aPL might support the eventual clinical decision but further investigation is warranted.

Humanistic and cost burden of systemic sclerosis: A review of the literature
Source:Autoimmunity Reviews
Author(s): Aryeh Fischer, Evelina Zimovetz, Caroline Ling, Dirk Esser, Nils Schoof
BackgroundSystemic sclerosis (SSc), or systemic scleroderma, is a chronic multisystem autoimmune disease characterised by widespread vascular injury and progressive fibrosis of the skin and internal organs. Patients with SSc have decreased survival, with pulmonary involvement as the main cause of death. Current treatments for SSc manage a range of symptoms but not the cause of the disease. Our review describes the humanistic and cost burden of SSc.MethodsA structured review of the literature was conducted, using predefined search strategies to search PubMed, Embase, and the Cochrane Library. Grey literature searches also were conducted.ResultsIn total, 2226 articles were identified in the databases and 52 were included; an additional 10 sources were included from the grey literature. The review identified six studies reporting relevant cost estimates conducted in five different countries and four studies that assessed the humanistic burden of SSc. Total direct annual medical costs per patient for Europe varied from €3544 to €8452. For Canada, these costs were reported to be from Can$5038 to Can$10,673. In the United States, the total direct health care costs were reported to be US$17,365 to US$18,396. Different key drivers of direct costs were reported, including hospitalisations, outpatients, and medication. The total annual costs per patient were reported at Can$18,453 in Canada and varied from €11,074 to €22,459 in Europe. Indirect costs represented the largest component of the total costs. EQ-5D utility scores were lower for patients with SSc than those observed in the general population, with reported mean values of 0.49 and 0.68, respectively. The average value of the Health Assessment Questionnaire for patients with SSc was significantly higher than the control population (0.94), and the average value of the SF-36 was significantly lower than the control population: 49.99 for the physical dimension and 58.42 for the mental dimension.ConclusionsOverall, there is a paucity of information on the burden of SSc. Nonetheless, our review indicates that the quality of life of patients with SSc is considerably lower than that of the general population. In addition, SSc places a considerable economic burden on health care systems and society as a whole.

Author(s): Carlo Salvarani, Alessandra Soriano, Francesco Muratore, Yehuda Shoenfeld, Daniel Blockmans
The increasing availability and improvement of imaging techniques are deeply influencing diagnosis and work-up of patients affected with vasculitis, particularly those with large vessel vasculitis (LVV). Fluorodeoxyglucose (18F-FDG) positron emission tomography (PET), especially when integrated with computed tomography (CT), is taking hold as a useful diagnostic technique to examine the aorta and the other large vessels in giant cell arteritis (GCA) with concomitant large vessel involvement (LV-GCA). In this paper we examined the progresses performed in this field in the last twenty years and the evidence available so far according to two different points of view ('pros' and 'cons'), in order to give a comprehensive answer to a still open question about the role of PET/CT in the diagnosis and follow-up of GCA.

Neutrophil extracellular traps (NETs) in autoimmune diseases: A comprehensive review

The structures named neutrophil extracellular traps (NETs) are fibrous networks which protrude from the membrane of activated neutrophils. NETs are found in a variety of conditions, such as infection, malignancy, atherosclerosis, and autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV), psoriasis, and gout. The impact of NETs on the development mechanisms of autoimmune diseases are proposed to arise from an imbalance between "NETosis" which is a process of NET formation and NET degradation. Neutrophils, interleukin-8, ANCA and other many inflammatory molecules are considered to play a key role in NET formation. In this way, prolonged exposure to these abnormal cascade of NETs affect autoimmunity and increase the chance of systemic organ damage. In this review, we will discuss the specific roles of various inflammatory molecules in relationship to NETs. We will also provide evidence of the importance of NETs in the pathogenesis of autoimmune diseases and furthermore highlight the potential that target therapies may influence NET formation and associated molecules.

Despite the improvement in the quality of life of patients with SLE due to scientific and technological advances, SLE remains a disease that over the years may produce irreversible damage to patients. Osteoporosis and secondary bone fractures are two of the major causes of irreparable injury in patients with SLE. Vitamin D insufficiency may play a vital role both in reduced Bone Mineral Density (BMD) and in the appearance of fractures, although its mechanisms of action are still unclear. We performed a systematic review of the literature in order to determine the prevalence and predictors of reduced vitamin D plasma levels, bone loss and the presence of fractures in SLE patients. Our review encompassed all English-language publications using Medline and EMBase electronic databases from their inception (1966 and 1980, respectively) to December 2016. We included all intervention studies and observational studies in which vitamin D plasma levels, BMD and bone loss were measured and applied to patients with SLE. Previous studies suggested an increase in bone loss and fracture in patients with SLE compared with general population and although there is a high prevalence of vitamin D insufficiency in the general population, previous studies had demonstrated lower vitamin D levels in patients with SLE compared to age-matched controls. The etiology of reduced bone mass and reduced vitamin D plasma levels in SLE is multifactorial and includes a variety of intrinsic factors related to the disease itself and treatment side effects. SLE patients are at risk for developing these two comorbidities (reduced vitamin D plasma levels and low BMD) and it is therefore essential to study, monitor, prevent and treat bone metabolism disorders in SLE patients.

Is ACPA positivity the main driver for rheumatoid arthritis treatment? Pros and cons
Source:Autoimmunity Reviews
Author(s): Stefano Alivernini, Mauro Galeazzi, Hagit Peleg, Barbara Tolusso, Elisa Gremese, Gianfranco Ferraccioli, Yaakov Naparstek
Rheumatoid Arthritis (RA) is an autoimmune chronic disease that is characterized by the positivity of various antibodies, the most specific being autoantibodies against citrullinated antigens (ACPA). Despite ACPA are not arthritogenic by themselves, ACPA positive individuals have high risk of RA development and ACPA positivity is associated with severe erosive phenotype and higher mortality rate compared to seronegative RA. Moreover, ACPA status is associated with favorable response to biologics targeting pathways involving autoantibody producing cells as B lymphocytes. In the current review we have discussed the pros and cons on the available scientific evidences, regarding the diagnostic, prognostic and management implications of ACPAs in RA.

Cytotoxicity and potential anti-inflammatory activity of velutin on RAW 264.7 cell line differentiation: Implications in periodontal bone loss
Source:Archives of Oral Biology, Volume 83
Author(s): Carlos Brito, Alexander Stavroullakis, Tatiane Oliveira, Anuradha Prakki
ObjectivesHypoxia-inducible factor-1α (HIF-1α) has been implicated in periodontal tissue inflammation and possibly in osteoclast differentiation, while polyphenols are known to be anti-inflammatory natural compounds that are capable of regulating the NF-κB protein complex pathway. The objective of this study was to investigate cytotoxicity and HIF-1α expression through the NF-κB pathway by polyphenol velutin (Euterpe oleracea Mart.), found in the pulp of acai fruit, during inflammatory RAW 264.7 differentiation.DesignRAW 264.7 mouse monocyte macrophage cells were stimulated with RANKL (30ng/mL) and Porphyromonas gingivalis lipopolysaccharide (1μg/mL). Cells were treated with various concentrations of velutin (0.5–2μM) to check for viability, morphology, osteoclast differentiation, and HIF-1α expression (Western blot).ResultsAlamar blue cell viability assay showed no toxicity to RAW cells with the use of velutin in all concentrations tested (p>0.05). Velutin did not induce cell apoptosis based on caspase 3/7 assay (p>0.05). Fluorescence images stained by DAPI showed no alteration in the morphology of RAW cell nuclei (p>0.05) treated with velutin. TRAP assays demonstrated a dose-dependent reduction in osteoclast formation by velutin when compared with control (p<0.05). Velutin showed a reduction in HIF-1α expression related to IκB phosphorylation when compared with control (p<0.001).ConclusionsAt the tested concentrations, velutin was not cytotoxic to RAW 264.7 and differentiated cells. Velutin reduced osteoclast differentiation and downregulated HIF-1α through the NF-κB pathway.

Alternate dosing regimens of brentuximab vedotin for CD30+ cutaneous T-cell lymphoma: reply from authors
Abstract
We thank the authors Lewis, Kim, and Duvic, for their reaction to our article.
The increasingly personalised medicine should also take into account individual tumour entities and their inter-individual pathways.
Therefore, we can only welcome and sustain the comments. As described in our article, it is possible, in some patients, to reduce the dose and interval frequency of Brentuximab Vedotin (BV), while continuing to have good efficacy.

Chronic actinic dermatitis: successful treatment with PUVA photochemotherapy
Abstract
Chronic actinic dermatitis (CAD) is a debilitating photodermatosis. First line therapy consists of strict photoprotection and topical corticosteroids. Second line therapy uses systemic immunosuppression. However an alternative is needed for patients with severe CAD who cannot use systemic immunosuppressants.1,2 Case reports and small case series suggest that PUVA may be effective.3-6

Alternate dosing regimens of brentuximab vedotin for CD30+ cutaneous T-cell lymphoma
Abstract
Stranzenbach et al. propose alternate dosing regimens of brentuximab vedotin (BV) for CD30+ cutaneous T-cell lymphomas (CTCLs) such as mycosis fungoides (MF) and primary cutaneous anaplastic large cell lymphoma (pcALCL).1 They emphasize that lower doses or less frequent dosing schedules for CTCL may be equally effective while limiting adverse events.
The authors indicate that CTCLs may require less aggressive therapy than systemic lymphomas such as systemic ALCL (sALCL) or Hodgkin lymphoma (HL).

The value and pitfalls of biologics registries for psoriasis
Abstract
We are pleased that our initial perspective article in the BJD have sparked discussions. As indicated in our initial paper, our main critical point is the exponential growth in publications relating to drug survival as an efficacy assessment based on non-randomized registry data (Figure 1). Indeed, we ourselves have performed such drug survival analyses.1 While we agree that methods such as propensity score matching could even out some of the between-drug variations in patient characteristics, propensity score matching is a rare sight in drug survival studies.

Registries as a real-world cohort studies that are useful and necessary in the pyramid of evidence
Abstract
Egeberg et al1 enriched us by describing the limitations of registries in psoriasis, but focusing their critical perspective on a misguided outcome measure such as "drug survival". We agree that clinicians and researchers should be cautious when using that proxy measure.2,3However, the frequent use of this poor outcome should not cast doubts over all the capabilities of registries.

Recovery from Repeated Sudden Hearing Loss in a Patient with Takayasu’s Arteritis Treated with Hyperbaric Oxygen Therapy: The First Report in the Literature
Hearing loss has been rarely reported in Takayasu's arteritis, may present as Sudden Sensorineural Hearing Loss, and usually responds well to corticosteroid therapy. Hyperbaric Oxygen Therapy is commonly used as a supplementary treatment to corticosteroids for Sudden Sensorineural Hearing Loss. We present the case of a 36-year-old woman with Takayasu's arteritis who had two episodes of sudden hearing loss involving one ear at a time with an 11-month delay between each episode. During the first episode, the patient was treated with high-dose intramuscular corticosteroids with a temporary improvement of auditory threshold that deteriorated 14 days after cessation of therapy. In the second episode, Hyperbaric Oxygen Therapy was associated with corticosteroids, with improvements in both ears, including the one that was unresponsive in the long term to previous pharmacologic therapy.
