- Pituitary tumors and subsequent treatment with endoscopic transsphenoidal surgery (ETSS) may cause injury to suprasellar structures, causing long-term fatigue and neurocognitive impairment. A method to quantify brain injury after ETSS is not available. In this prospective, exploratory study of patients undergoing ETSS for pituitary tumors, a novel approach to detect possible neuronal damage is presented. Plasma concentrations of brain injury biomarkers (glial fibrillary acidic protein [GFAP], tau, and neurofilament light [NFL]) were measured the day before surgery, immediately after surgery, at day 1 and 5, and at 6 and 12months after surgery, using enzyme-linked immunosorbent assays. The association between the increase of biomarkers with preoperative tumor extension and postoperative patient-perceived fatigue was evaluated. Suprasellar tumor extension was assessed from MRI scans, and self-perceived fatigue was assessed using the Multidimensional Fatigue Inventory before and 6months after surgery. Thirty-five patients were included in the analysis. Compared to baseline, GFAP showed a maximal increase at day 1 after surgery (p=0.0005), tau peaked postoperatively on the day of surgery (p=0.019), and NFL reached its maximum at day 5 after surgery (p<0.0001). The increase in GFAP correlated with preoperative chiasmal compression (p=0.020). The increase in tau was correlated with preoperative chiasmal (p=0.011) and hypothalamus compression (p=0.016), and fatigue score 6months after surgery (p=0.016). In conclusion, the concentrations of brain injury biomarkers in blood increased after ETSS for pituitary tumors. The results indicate that postoperative plasma GFAP and tau might reflect astroglial and neuronal damage after ETSS.

- Objective Headache is a common symptom among patients with pituitary tumors, as it is in the general population. The aim of the study was to investigate headache as a symptom in patients with pituitary tumors before and 6 months after endoscopic transsphenoidal surgery (TSS). Design This is a prospective observational cohort study. Setting This study was conducted at university tertiary referral hospital. Participants A total of 110 adult patients underwent endoscopic TSS for pituitary tumors. Main Outcome Measures The Migraine Disability Assessment (MIDAS) questionnaire was used before and 6 months after surgery for the assessment of headache. Clinical variables with potential influence on headache were analyzed. Results Sixty-eight (62%) patients experienced headaches at least once during the 3 months before surgery. Thirty (27%) patients reported disabling headache before surgery, with younger age being an independent associated factor ( p <0.001). In patients with disabling headache before surgery, the median (interquartile range) MIDAS score improved from 78 (27-168) to 16 (2-145; p =0.049), headache frequency decreased from 45 (20-81) to 14 (4-35) days ( p =0.009), and headache intensity decreased from 6 (5-8) to 5 (4-7) ( p =0.011) after surgery. In total, 16 of the 30 (53%) patients reported a clinically relevant improvement and five (17%) a clinically relevant worsening. Four (5%) patients developed new disabling headache. No predictor for postoperative improvement of headache was identified. Conclusion In this prospective study, the results show that disabling headache improves following endoscopic TSS in a subset of patients with pituitary tumors. However, no predictive factors for improvement could be identified.

- © 2021 Thieme Medical Publishers, Inc.. All rights reserved. Objectives Despite the limited invasiveness of endoscopic transsphenoidal surgery (ETSS), some degree of nasal structure destruction is unavoidable. Our objective was to evaluate sinonasal morbidity and self-reported health before and 6 months after ETSS for pituitary tumors, and to identify possible predictive factors for deterioration in sinonasal health. Design Prospective observational cohort study. Setting University tertiary referral hospital. Participants Totally 109 consecutive adult patients undergoing ETSS for pituitary tumors between 2015 and 2019. Main Outcome Measures Sinonasal symptoms and self-reported health before and 6 months after ETSS, assessed by the Sinonasal Outcome Test (SNOT-22) and the EQ-5D questionnaire. Predictive factors for postoperative deterioration in sinonasal symptoms. Results The overall SNOT-22 score did not change, but the score of the rhinologic domain of SNOT-22 worsened from 6.0 ± 5.9 before to 8.0 ± 7.4 6 months after surgery (p = 0.011). The EQ-5D visual analog scale improved from 64.0 ± 22.9 before to 71.1 ± 18.7 6 months after surgery (p = 0.00088). Univariate and multivariable regression analyses showed that prior sinonasal surgery was associated with a significant worsening in rhinologic symptoms 6 months after surgery (p = 0.046 and p = 0.020, respectively). Conclusions Although self-reported overall health improved, significant deterioration of rhinologic symptoms was seen 6 months after ETSS. This information is important for preoperative patient counselling. Further refinement of the surgical technique and follow-up strategies to reduce postoperative sinonasal morbidity could be of value, especially in patients who have undergone prior sinonasal surgery.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE Despite ample experience in surgical treatment of pituitary adenomas, little is known about objective indices that may reveal risk of visual impairment caused by tumor growth that leads to compression of the anterior visual pathways. This study aimed to explore diffusion tensor imaging (DTI) as a means for objective assessment of injury to the anterior visual pathways caused by pituitary adenomas. METHODS Twenty-three patients with pituitary adenomas, scheduled for transsphenoidal tumor resection, and 20 healthy control subjects were included in the study. A minimum suprasellar tumor extension of Grade 2-4, according to the SIPAP (suprasellar, infrasellar, parasellar, anterior, and posterior) scale, was required for inclusion. Neuroophthalmological examinations, conventional MRI, and DTI were completed in all subjects and were repeated 6 months after surgery. Quantitative assessment of chiasmal lift, visual field defect (VFD), and DTI parameters from the optic tracts was performed. Linear correlations, group comparisons, and prediction models were done in controls and patients. RESULTS Both the degree of VFD and chiasmal lift were significantly correlated with the radial diffusivity (r = 0.55, p < 0.05 and r = 0.48, p < 0.05, respectively) and the fractional anisotropy (r = -0.58, p < 0.05 and r = -0.47, p < 0.05, respectively) but not with the axial diffusivity. The axial diffusivity differed significantly between controls and patients with VFD, both before and after surgery (p < 0.05); however, no difference was found between patients with and without VFD. Based on the axial diffusivity and fractional anisotropy, a prediction model classified all patients with VFD correctly (sensitivity 1.0), 9 of 12 patients without VFD correctly (sensitivity 0.75), and 17 of 20 controls as controls (specificity 0.85). CONCLUSIONS DTI could detect pathology and degree of injury in the anterior visual pathways that were compressed by pituitary adenomas. The correlation between radial diffusivity and visual impairment may reflect a gradual demyelination in the visual pathways caused by an increased tumor effect. The low level of axial diffusivity found in the patient group may represent early atrophy in the visual pathways, detectable on DTI but not by conventional methods. DTI may provide objective data, detect early signs of injury, and be an additional diagnostic tool for determining indication for surgery in cases of pituitary adenomas.

Tidskriftsartikel (refereegranskat)abstract
- Previous randomized studies comparing the two commonly used palliative treatments for incurable esophageal cancer, i.e. stent insertion and intraluminal brachytherapy, have revealed the pros and cons of each therapy. While stent treatment offers a more prompt effect, brachytherapy results in more long-lasting relief of dysphagia and a better health-related quality of life (HRQL) in those living longer. This prospective pilot study aimed to explore the feasibility and safety of combining these two regimes and incorporating a single high dose of internal radiation. Patients with newly diagnosed, incurable cancer of the esophagus and dysphagia were eligible for inclusion, and stent insertion followed by a single dose (12Gy) of brachytherapy was performed as a two-stage procedure. Clinical parameters including HRQL and adverse events were registered at inclusion, and 1, 2, 3, 6, and 12 months later. Twelve patients (nine males) with a median age of 73 years (range 54-85) were included. Stent insertion followed by a single dose of brachytherapy was successfully performed in all but one patient who was treated with stent only. Relief of dysphagia was achieved in the majority of cases (10/11, P < 0.05), but HRQL did not improve except for dysphagia-related items. Only minor adverse events, including chest pain, reflux, and restenosis, were reported. The median survival time after inclusion was 6.6 months. Our conclusion is that the combination of stent insertion and single high-dose brachytherapy seems to be a feasible and safe palliative regime in patients with advanced esophageal cancer. Randomized trials comparing the efficacy of this strategy to stent insertion or brachytherapy alone are warranted.

- OBJECTIVES/HYPOTHESIS: Eosinophilic esophagitis is a rather new disease entity diagnosed with increasing frequency. The main symptoms in adults are dysphagia and food impaction. The aim of this review is to summarize the present knowledge about adult eosinophilic esophagitis, and in particular to cast light on certain issues of concern for the ear, nose, and throat (ENT) specialist. STUDY DESIGN: Scientific review. METHODS: The biomedical literature on adult eosinophilic esophagitis was reviewed regarding epidemiology, etiology, subjective symptoms and objective signs, diagnosis, treatment, and prognosis with an emphasis on matters of interest for the ENT specialist. PubMed was used as the search engine. RESULTS: Among the 393 papers on eosinophilic esophagitis published in PubMed, only 162 deal with adults. During the last few decades, the annual number of papers has been exponentially increasing. A high prevalence of eosinophilic esophagitis in combination with a diagnostic delay suggests the existence of an unacceptable number of undiagnosed cases. This calls for increased attention. Endoscopic examination, including proper biopsies, verifies the diagnosis. Untreated, the disease will lead to substantial distress and in some cases even strictures. Keeping the diagnosis in mind will avoid improper treatment and the risk of accidental perforation. CONCLUSIONS: It is imperative that ENT specialists recognize patients with eosinophilic esophagitis.

Tidskriftsartikel (refereegranskat)abstract
- Cancer of the pharyngoesophageal junction (PEJ) is associated with late onset of symptoms, high morbidity, and a dismal prognosis. Radical surgery with pharyngolaryngectomy and reconstruction with a free vascularized jejunal transplant has been increasingly practiced in the treatment of these patients. This strategy is not devoid of challenges, and the present study is aimed at evaluating the long-term functional outcome among patients who have undergone such surgical treatment. Ten patients (mean age 59 years) with a mean follow-up time of 54 months were included. Clinical assessment, health-related quality of life (HRQL) questionnaires, and a standardized radiography examination were used for evaluation. The Karnofsky index ranged from 60 to 90 (mean 82). Global QL scores (EORTC QLQ-C30) had a mean value of 74, and the mean scores for dysphagia-related items of the EORTC QLQ OES-18 questionnaire were within the lower range. Radiographic signs of disturbed bolus transport through the jejunal transplant were found in all patients examined despite the grading of dysphagia from 0 to 1. The Watson dysphagia score varied between 0.5 and 45.0 (mean 16.2). No correlations were found between radiographic findings and the clinical evaluations or the outcomes assessed by the HRQL questionnaires. HRQL was found to be generally good after cancer of the PEJ and jejunal transplant insertion. Most patients reported mild dysphagia. Radiologic signs of disturbed bolus passage were common, but their clinical impact seemed questionable.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND/AIMS: To evaluate the functional outcome of a reconstruction by a free vascularized jejunal transplant combined with a voice prosthesis after chemoradiotherapy and surgery for proximal oesophageal or hypopharyngeal cancer. METHODS: Seven patients (6 men, mean age 52 years, range 28-70) with squamous cell cancer in the proximal oesophagus (n = 6) or the hypopharynx received preoperative chemoradiotherapy (40.8 Gy, cisplatinum and 5-FU) followed by a circumferential pharyngolaryngectomy and resection of the proximal oesophagus. A single-stage reconstruction was carried out with a free jejunal transplant using a microsurgical technique. A tracheojejunal puncture and insertion of a voice prosthesis (Provox I) was performed after 3 months in suitable cases. RESULTS: All operations had a per- and postoperative uneventful course. Five patients were alive after a mean follow-up time of 5 years and 7 months after surgery (range 3 years 4 months to 7 years 10 months), while 2 patients died from metastases within 2 years after surgery. Postoperative examination showed histopathological down-staging in all cases. Relief of dysphagia was achieved in most cases. Good or average speech was recorded in 3 patients. CONCLUSION: Reconstruction after radical resection for proximal oesophageal and hypopharyngeal cancer can be carried out with low mortality, acceptable morbidity and a promising functional outcome.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Eosinophilic oesophagitis is thought to be an isolated oesophageal disease associated with biopsy-verified eosinophilia of the squamous cell epithelium of the oesophagus. Food- or aeroallergens have been suggested to be the cause of eosinophilic oesophagitis; however, as these allergens pass through the pharynx sharing the same squamous cell epithelium, eosinophilic infiltration could be expected also here. Whether this is true or not has hitherto not been clarified. AIM: To find out whether eosinophilia is present also within the pharyngeal epithelium in patients with eosinophilic oesophagitis. METHODS: In all, 10 patients (median age 34, range 15-70) with biopsy-verified eosinophilic oesophagitis [peak count >20 eosinophils per high power field (hpf)] were biopsied also in the pharynx. The biopsies underwent histopathological examination and at each level, the peak number of eosinophils per hpf was counted. RESULTS: None of the patients examined was found to have eosinophilia within the squamous cell epithelium of the pharynx (median peak count 0, range 0-1). CONCLUSIONS: The pronounced eosinophilic infiltration in eosinophilic oesophagitis appears to be an isolated oesophageal phenomenon not shared by the adjoining organ sites and in particular, not by the pharynx. This may have implications for future research.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to validate the Swedish version of the dysphagia-specific quality-of-life questionnaire, the M. D. Anderson Dysphagia Inventory (MDADI). Patients with oropharyngeal dysphagia due to neurologic disease (n=30) and head and neck (H&N) cancer patients with post-treatment subjective dysphagia (n=85) were compared to an age- and gender-matched nondysphagic control group (n=115). A formal forward-backward translation was performed and followed international guidelines. Validity and reliability were tested against the Short-Form 36 (SF-36) and Hospital Anxiety and Depression Scale (HADS). Internal-consistency reliability was calculated by means of Cronbach's α coefficient. Test-retest reliability was assessed by intraclass correlation (ICC). Convergent and discriminant validity were assessed by correlations between MDADI, SF-36, and HADS. Known-group validity was examined and statistically tested. Of 126 eligible patients, 115 agreed to participate (response rate=91.3%). The age of the participants ranged between 37 and 92 years. Most of the MDADI items showed good variability and only minor floor or ceiling effects in solitary items were found. The internal-consistency reliability (Cronbach's α) of the MDADI total score was 0.88 (after correction for systematic errors in the subjects' responses to two reversed questions). All estimates reached over the satisfactory >0.70 reliability standard for group-level comparison. ICC ranged between 0.83 and 0.97 in the test-retest. The mean MDADI total score was 66.9 (SD=14.7) for the H&N cancer patients, 65.0 (16.9) for the neurologic patients, and 97.5 (4.4) for the control group (P<0.001; study patients vs. controls). The MDADI was also sensitive to disease severity as measured by different food textures. The Swedish version of the MDADI showed good psychometric properties and is a valid instrument to assess dysphagia-related quality of life. It was also shown to be a reliable instrument after correction for systematic errors in the subjects' responses to two reversed questions. Its known-group validity enables the differentiation between dysphagic and nondysphagic patients for group-level research.

- Background: This randomized study aimed to evaluate the effects of the Shaker head-lift exercise (HLE) to improve dysphagia following oncologic treatment for head and neck cancer (HNC). Methods: Patients with dysphagia following oncologic treatment for HNC were randomly assigned to intervention (n = 23) or control (standard dysphagia management, n = 24) groups. Swallowing was evaluated at baseline and at 8-week follow-up using flexible endoscopic evaluation of swallowing (FEES) and self-perceived swallowing with the Eating Assessment Tool (EAT-10). Analysis was performed regarding secretion, initiation of swallow, residue after swallowing, and penetration/aspiration. Results: Few statistically significant differences were found in the FEES analysis. Some improvement of self-perceived swallowing function was found in both groups. Adherence to training was high. Conclusions: This randomized study regarding the effect of the HLE demonstrated that swallowing outcome measures used in assessment of FEES did not improve in patients treated with radiotherapy for patients with dysphagia following HNC.

Tidskriftsartikel (refereegranskat)abstract
- Background: Critically ill COVID-19 patients may develop acute respiratory distress syndrome and the need for respiratory support, including mechanical ventilation in the intensive care unit. Previous observational studies have suggested early tracheotomy to be advantageous. The aim of this parallel, multicentre, single-blinded, randomized controlled trial was to evaluate the optimal timing of tracheotomy. Methods: SARS-CoV-2-infected patients within the Region Vastra Gotaland of Sweden who needed intubation and mechanical respiratory support were included and randomly assigned to early tracheotomy (<= 7 days after intubation) or late tracheotomy (>= 10 days after intubation). The primary objective was to compare the total number of mechanical ventilation days between the groups. Results: One hundred fifty patients (mean age 65 years, 79% males) were included. Seventy-two patients were assigned to early tracheotomy, and 78 were assigned to late tracheotomy. One hundred two patients (68%) underwent tracheotomy of whom sixty-one underwent tracheotomy according to the protocol. The overall median number of days in mechanical ventilation was 18 (IQR 9; 28), but no significant difference was found between the two treatment regimens in the intention-to-treat analysis (between-group difference:- 1.5 days (95% CI -5.7 to 2.8); p= 0.5). A significantly reduced number of mechanical ventilation days was found in the early tracheotomy group during the per-protocol analysis (between-group difference: - 8.0 days (95% CI - 13.8 to - 2.27); p= 0.0064). The overall correlation between the timing of tracheotomy and days of mechanical ventilation was significant (Spearman's correlation: 0.39, p < 0.0001). The total death rate during intensive care was 32.7%, but no significant differences were found between the groups regarding survival, complications or adverse events. Conclusions: The potential superiority of early tracheotomy when compared to late tracheotomy in critically ill patients with COVID-19 was not confirmed by the present randomized controlled trial but is a strategy that should be considered in selected cases where the need for MV for more than 14 days cannot be ruled out.

- The purpose of this study was to evaluate the psychometric properties of the Swedish version of the Swallowing Quality of Life questionnaire (SWAL-QOL). The study design was cross-sectional and the study was performed in patients with subjective oropharyngeal dysphagia due to head and neck (H&N) cancer (n=85) or neurological disease (n=30) and in a sample of age- and gender-matched controls (mean age=63years, 57% males) without subjective dysphagia (n=115). The Short-Form 36 (SF-36) and Hospital Anxiety and Depression Scale (HADS) questionnaires were used for assessment of convergent and discriminant validity. The Swedish version of SWAL-QOL was well accepted, the response rate was high (>90%), and the number of missing items were very low (<1%). Overall, the questionnaire showed good to excellent psychometric properties, including floor and ceiling effects (range=0-16 and 0-21%), internal consistency [Cronbach's α>0.70 for all domains except Eating Duration (0.69) and Sleep (0.68)], test-retest reliability (intraclass correlations=0.75-0.98) and convergent and discriminant validity as assessed by correlations between SWAL-QOL and SF-36 and HADS. SWAL-QOL also proved able to differentiate between dysphagic and nondysphagic patients (P<0.00001) (known-groups validity) and sensitive to disease severity as measured by different food textures.

- Eosinophilic esophagitis (EoE) is a chronic immune/antigen-mediated disease, with dysphagia as the main symptom. The aim of this study was to survey symptoms and health-related quality of life in adult patients with EoE at least 1year after diagnosis and a 2-month course of topical corticosteroids. Forty-seven consecutive patients [79% males, mean age 49years (range 18-90years)] were evaluated using three different questionnaires at three different occasions: the Watson Dysphagia Scale (WDS), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Oesophageal Module 18 (EORTC QLQ-OES18) and the Short Form-36 (SF-36). The median time from diagnosis to the long-term follow-up was 23months (range 12-34months). The WDS scores and the EORTC QLQ-OES18 Dysphagia and Eating scale scores were improved after 2months of treatment (p=0.00007, p=0.01, p=0.004, respectively), as were the long-term follow-up scores (p=0.01, p=0.03, p=0.005, respectively), relative to the scores at diagnosis. In addition, the EORTC QLQ-OES18 Choking scores were improved after the steroid course (p=0.003) but not after the long-term follow-up. No significant differences were detected with respect to the SF-36 scores. In summary, EoE seems to be associated with a substantial burden of symptoms that improve significantly after treatment. A partial remission persists more than 1year after diagnosis and the discontinuation of medication. The WDS and the EORTC QLQ-OES18 appear to be sensitive instruments appropriate for surveillance in these patients.

- The aim of this study was to assess whether the symptom severity and health-related quality of life (HRQL) of patients with dysphagia and esophageal eosinophilia correlate with disease activity as expressed by the number of eosinophils in the esophageal mucosa. This study included newly diagnosed (n = 58) or relapsed patients (n = 7), where 40% were diagnosed in connection with esophageal bolus impaction. The mean age was 45 years (19-88), and 74% were men. Symptoms and HRQL were recorded using the Watson Dysphagia Scale (WDS), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Oesophageal Module 18 and the Short Form-36 Questionnaire. Histological samples gathered from the proximal and distal esophageal mucosa were stained using both hematoxylin and eosin (HE) and an immunohistochemical (IHC) technique against 'Eosinophil Major Basic Protein,' and the peak number of eosinophils per high-power field was assessed. More eosinophils were detected after IHC staining than HE staining (P < 0.001). No correlation was found between symptoms or the HRQL and the number of eosinophils. However, higher numbers of eosinophils at the proximal esophagus were found in patients with concomitant bolus impaction (IHC P < 0.05 and HE P < 0.05) and could serve as a risk marker.

- Eosinophilic esophagitis (EoE) afflicts both children and adults. It has been debated whether pediatric and adult EoE represent different disease entities. The objectives of this study were to determine if the blood eosinophil molecular pattern of children with EoE is: 1) distinct from that of healthy children; and 2) different from that of adults with EoE.Blood eosinophils from children and adults with EoE, and healthy controls, were analyzed with flow cytometry regarding levels of CD23, CD44, CD54, CRTH2, FOXP3 and galectin-10. Eosinophil FOXP3 and galectin-10 mRNA levels were determined by qPCR. The data was analyzed by using a multivariate method of pattern recognition.An eosinophil molecular pattern capable of distinguishing children with EoE from control children was identified. A smaller fraction of eosinophils from children with EoE expressed CD44 and a larger fraction expressed CRTH2 than the controls. Eosinophils from children with EoE also had higher levels of galectin-10 mRNA and lower levels of FOXP3 mRNA. The eosinophils from children with EoE had lower levels of surface CD54 and of FOXP3 mRNA compared with the eosinophils from the adult patients. A key finding was the detection in healthy individuals of age-related differences in the levels of several eosinophil markers.Children with EoE can be distinguished from healthy children based on the molecular patterns of their blood eosinophils. Age-related physiologic differences in eosinophil molecular patterns may partly explain the different blood eosinophil phenotypes in children versus adults with EoE.

- Eosinophilic esophagitis (EoE) is an antigen-driven T cell-mediated chronic inflammatory disease where food and environmental antigens are thought to have a role. Human eosinophils express the immunoregulatory protein galectin-10 and have T cell suppressive capacity similar to regulatory T cells (Tregs ). We hypothesized that one function of eosinophils in EoE might be to regulate the T cell-driven inflammation in the oesophagus. This was tested by evaluating the suppressive capacity of eosinophils isolated from the blood of adult EoE patients in a mixed lymphocyte reaction. In addition, eosinophilic expression of forkhead box protein 3 (FOXP3), the canonical transcription factor of Tregs , was determined by conventional and imaging flow cytometry, quantitative polymerase chain reaction (qPCR), confocal microscopy and immunoblotting. It was found that blood eosinophils from EoE patients had T cell suppressive capacity, and that a fraction of the eosinophils expressed FOXP3. A comparison of EoE eosinophils with healthy control eosinophils indicated that the patients' eosinophils had inferior suppressive capacity. Furthermore, a higher percentage of the EoE eosinophils expressed FOXP3 protein compared with the healthy eosinophils, and they also had higher FOXP3 protein and mRNA levels. FOXP3 was found in the cytosol and nucleus of the eosinophils from both the patients and healthy individuals, contrasting with the strict nuclear localization of FOXP3 in Tregs . To conclude, these findings suggest that the immunoregulatory function of eosinophils may be impaired in EoE.

- Swallowed topical corticosteroids are the standard therapy for eosinophilic esophagitis (EoE) in adults. Eosinophils in the blood of untreated EoE patients have an activated phenotype. Our aim was to determine if corticosteroids restore the phenotype of eosinophils to a healthy phenotype and if certain cell-surface molecules on blood eosinophils correlate with eosinophilic infiltration of the esophagus. Levels of eight surface markers on eosinophils from treated and untreated EoE patients were determined by flow cytometry and analyzed using multivariate methods of pattern recognition. Corticosteroid-treated EoE patients' eosinophils had decreased levels of CD18 compared to both untreated patients and healthy controls, but maintained their activated phenotype. CD18 expression correlated positively with eosinophil numbers in the esophagus and promoted the adherence of eosinophils to ICAM-1, ICAM-2, and to endothelial cells. The diminished expression of CD18 may be one mechanism behind the reduced entry of eosinophils into the esophagus in corticosteroid-treated EoE patients.

- This reference study aims to survey the bacterial flora of the healthy lower human esophagus and to compare it with that of the upper esophagus and oral mucosa. The use of biopsies, in addition to brush samples, allows inclusion of not only transient bacteria present on the surface but also bacteria residing in the epithelia, and the yield of the two methods can be compared. Forty patients scheduled for surgery for reasons with no known influence on esophageal flora and with no symptoms or endoscopic signs of esophageal disease were included. Samples were collected from the oral, upper esophageal, and lower esophageal mucosa using sealed brushes and biopsy forceps. Colonies cultivated on agar plates were classified and semiquantified. Twenty-three different bacterial species were identified, with similar strains present at the three sites. The most common group of bacteria was viridans streptococci, with an occurrence rate in brush samples and biopsies of 98% and 95%, respectively. The median number of species occurring in the oral cavity, upper esophagus, and lower esophagus was between 3 and 4 (range 0-7). The total number of species in the oral cavity was significantly higher when compared with either level in the esophagus, while the yields obtained by brush and biopsy sampling were highly correlated. Hence, the normal human esophagus is colonized with a resident bacterial flora of its own, which has similarities to that of the oral mucosa. There are diverse species that make up this flora, although in relatively low amounts. The most frequent inhabitants of the esophagus are streptococci, with an occurrence rate in brush samples and biopsies of 95-98%. Comparative studies of patients with eosinophilic esophagitis and gastroesophageal reflux disease are warranted.

- Background: The healthy human esophagus is colonized by bacteria similar to that of the oral mucosa. However, little is known about the microbiome of the esophagus in esophagitis or the possible role of bacteria in the inflammatory response.Aim: To survey bacterial diversity and compare the microbiome of the esophagus in subjects with gastro-esophageal reflux disease (GERD) and eosinophilic esophagitis (EoE).Material and methods: Seventeen subjects diagnosed with GERD and 10 with EoE underwent endoscopic examination with brush sampling and biopsies from the oral cavity, upper and lower esophagus. The samples were cultivated on agar plates, and bacterial growth was identified to the genus or species level and semi-quantified.Results: Significantly higher numbers of bacterial groups or species were found in specimens from the lower esophagus in subjects with EoE compared to subjects with GERD (median 4 (range 1-7) vs. 2 (range 0-6), p<.0014). Sixteen vs. 14 different bacterial groups or species were found in subjects with GERD and EoE, respectively, mostly in sparse or very sparse amounts. Alfa-streptococci (viridans streptococci) were the most common bacteria in both groups. Streptococci were present in all of the EoE-subjects but only in approximately 75% in lower esophagus of the GERD-subjects, regardless of the sampling method.Conclusion: Subjects with GERD had significantly less bacterial diversity in both oral and esophageal samples than EoE-subjects. Whether this discrepancy might be explained by an effect on the protective mucosal biofilm by the acidic content of the reflux in subjects with GERD remains unclear.

- Objectives The aim of this study was to analyze the timing of tracheotomy and the duration of mechanical ventilation and stay in the intensive care unit (ICU) in patients with COVID‐19 infection. Furthermore, we aimed to investigate tracheotomy complications and mortality. Methods Consecutive patients with COVID‐19 infection admitted to the Department of Infectious Diseases in Gothenburg, Sweden were identified. Medical records were retrieved and retrospectively assessed. Results One hundred eighty‐eight patients with COVID‐19 infection requiring hospital care were identified. Of these, 116 patients were critically ill and intubated, and 55 patients underwent tracheotomy. The mean time from endotracheal intubation to tracheotomy was 12days (range 5‐28days). There was a correlation between the timing of tracheotomy and the duration of mechanical ventilation, where a shorter time between intubation and tracheotomy was correlated with a shorter duration of mechanical ventilation (r .58, P<.001), and a correlation was identified between the timing of tracheotomy and the duration of ICU stay (r .52, P<.001). Perioperative hypoxemia was registered in 9% of tracheotomies performed, whereas postoperative bleeding was observed in 27% of cases, the majority of which were minor. Conclusions This retrospective cohort study indicates that early tracheotomy is related to a reduced need for mechanical ventilation and a shorter duration of stay in the ICU in severe cases of COVID‐19 disease. Complications during and after tracheotomy in this specific cohort included risk perioperative hypoxia and postoperative bleeding. Prospective randomized controlled trials would be of value to confirm these findings.

- The aim of the study was to validate the Watson scale, the Ogilvie scale, and the Goldschmid scale for assessment of dysphagia due to malignancy of the esophagus. After translation of the scales to Swedish, 35 patients with dysphagia due to esophageal malignancy were asked to participate. On day 1, patients were asked to fill in the questionnaires. The patients also kept a food diary for 4 consecutive days, for assessment of actual swallowing ability. On day 10, the patients were asked to fill in the scales again, to control for individual variability. As an external control group, 29 healthy volunteers were asked to fill in the questionnaires once. External validation was done against actual swallowing ability, and against the European Organization for Research and Treatment of Cancer scales QLQ-C30 and QLQ-OG25, which are already validated quality of life scales for malignancy. Reliability in the categorical variables (Ogilvie and Goldschmid) showed weighted kappa values of 0.52 and 0.54, respectively. For the Watson scale and the Dysphagia module of QLQ-OG25, the intraclass correlation coefficients were 0.68 and 0.80, respectively. Correlations between all scales were good to excellent with values of correlation coefficients (rs) between 0.69 and 0.88, with the strongest correlations between the Ogilvie score and the dysphagia module in QLQ-OG25. These latter two scales had the strongest correlation to the food diary (rs = 0.72). Although the Ogilvie scale was superior, all the three scales showed good reliability and are thus judged to have good validity for assessment of dysphagia due to esophageal malignancy. © The Author(s) 2018.

- Eosinophilic esophagitis (EoE) and gastroesophageal reflux disease (GERD) share many histopathological features; therefore, markers for differentiation are of diagnostic interest and may add to the understanding of the underlying mechanisms. The nitrergic system is upregulated in GERD and probably also in EoE. Esophageal biopsies of patients with EoE (n = 20), GERD (n = 20), and healthy volunteers (HVs) (n = 15) were exposed to antibodies against inducible nitric oxide synthase (iNOS), nitrotyrosine, eosinophilic peroxidase, eotaxin-3, and galectin-3. The stained object glasses were randomized, digitized, and blindly analyzed regarding the expression of DAB (3,3 '-diaminobenzidine) by a protocol developed in QuPath software. A statistically significant overexpression of iNOS was observed in patients with any of the two inflammatory diseases compared with that in HVs. Eotaxin-3 could differentiate HVs versus inflammatory states. Gastroesophageal reflux patients displayed the highest levels of nitrotyrosine. Neither iNOS nor nitrotyrosine alone were able to differentiate between the two diseases. For that purpose, eosinophil peroxidase was a better candidate, as the mean levels increased stepwise from HVs via GERD to EoE. iNOS and nitrotyrosine are significantly overexpressed in patients with EoE and GERD compared with healthy controls, but only eosinophil peroxidase could differentiate the two types of esophagitis. The implications of the finding of the highest levels of nitrotyrosine among gastroesophageal reflux patients are discussed.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The Nasal Obstruction Symptom Evaluation (NOSE) scale is a symptom-specific quality-of-life questionnaire for patients suffering from nasal obstruction. The instrument is designed specifically for patients with septal deviation and for the evaluation of the outcome of septoplasty. The aim of this study was to validate a Swedish version of the NOSE instrument for use in clinical practice and research.Methods: A Swedish version of the NOSE was tested in a case group consisting of 125 subjects with nasal obstruction (of which 31 underwent septoplasty) and a control group consisting of 65 healthy subjects. Base line data for the case and control groups were used to evaluate face validity, known groups validity, construct validity, internal consistency and factor structure analysis. Fifty participants in both the case groups and control groups were assessed both at baseline and after 2 weeks to evaluate test-retest reliability. The participants who underwent septoplasty were assessed at baseline and after 3-6 months to evaluate responsiveness.Results: The S-NOSE was found to be reliable, valid, and responsive. Both Cronbach's alpha and McDonald Omega coefficients were > 0.7, and the intra class coefficient was 0.942. The S-NOSE scores were significantly correlated with nasal patency VAS in both the case group and the control group (p < .001 and p = .018, respectively). After septoplasty, the mean S-NOSE score were significantly improved (p < .001). Furthermore, the S-NOSE was shown to have excellent and robust psychometric properties.Conclusion: The S-NOSE can be recommended in both clinical practice and research to evaluate the outcome of septoplasty in Swedish-speaking populations.

- Background Dysphagia is common following treatment for head and neck cancer (HNC) and intervention to improve swallowing function is warranted. This study aimed to evaluate the efficacy of the Shaker head-lift exercise (HLE) to improve dysphagia in HNC patients. Methods Patients treated for HNC with radiochemotherapy and with subsequent dysphagia were randomly assigned to intervention (HLE, n = 25) and control (standard dysphagia management, n = 27) groups. Videofluoroscopic evaluation of penetration-aspiration, initiation, residue, movement of selected structures, and self-perceived swallowing function, before and after 8 weeks of treatment, were compared. Results Although adherence to training was high, no statistically significant differences in objectively measured swallowing function between the groups or within-group changes were found. Self-perceived swallowing function improved in the intervention group. Conclusions In this HNC population, neither HLE nor standard dysphagia management improved objectively measured swallowing function as evaluated after 8 weeks. Future research focusing on finding effective interventions for dysphagia is warranted.

- Objectives Topical corticosteroids are considered a cornerstone in the treatment of patients with eosinophilic esophagitis. The aim of this study was to evaluate the benefit of using mometasone furoate spray versus placebo on dysphagia and health-related quality of life in these patients. Material and Methods Consecutive, newly diagnosed adult patients with eosinophilic esophagitis were randomized and treated with either 200 micrograms of orally administered topical mometasone furoate or placebo 4 times daily for 8 weeks. Symptoms and quality of life were evaluated using questionnaires including the Watson Dysphagia Scale, the European Organization for Research and Treatment of Cancer Quality of Life-Oesophageal Module 18 and the Short Form-36 before and after treatment. Results In the intention-to-treat analysis (n = 36) the Watson Dysphagia Scale score after mometasone treatment was reduced by 6.5 (median, p < .01) compared with 0 (median, ns) in the placebo group. The benefit of mometasone over placebo was significant (p < .05). In the per-protocol analysis (n = 33) the Watson Dysphagia Scale score was reduced by 5 (median, p = .01) after mometasone treatment compared with 0 (median, ns) in the placebo group. The advantage of mometasone over the placebo was significant (p < .05). The benefit of using mometasoneas evaluated by the two quality of life questionnaires was, however, insignificant. Conclusions Our finding suggests that in adult patients with eosinophilic esophagitis, topical mometasone furoate exerts a beneficial effect compared with placebo regarding the main symptom, i.e., dysphagia. A corresponding benefit could not be verified regarding the various quality of life measurements.
