Association between preoperative serum C-reactive protein level and leukocyte count and postoperative pain after otolaryngological surgery.

PURPOSE: To determine whether the preoperative inflammatory serum C-reactive protein (CRP) and leukocyte count (LEUK) are associated with postoperative pain and complaints after otolaryngological surgery. METHODS: Retrospective evaluation of 680 patients (33% female, median age 50 years) receiving otolaryngological surgery between November 2008 and March 2017 in a tertiary university hospital. Postoperative pain on the first postoperative day was assessed using the validated questionnaire of the German-wide project Quality Improvement in Postoperative Pain Treatment (QUIPS) including a numeric rating scale for assessment of postoperative pain (NRS, 0-10). The influence of preoperative parameters including CRP and LEUK on patients' postoperative pain was estimated. RESULTS: Mean CRP value was 15.6 ± 34.6 mg/l and mean LEUK value 7.8 ± 3.2 Gpt/l. Patients with pharyngeal surgery had the highest CRP values (34.6 ± 52.9 mg/l), highest LEUK values (9.2 ± 4.2 Gpt/l) and the highest pain levels (3.1 ± 2.4 NRS) compared to all other surgical procedures (all p < 0.05). Higher postoperative pain was associated with LEUK values > 11.3 Gpt/l (r = 0.093, p = 0.016) and higher preoperative chronic pain (r = 0.127, p = 0.001). Multivariate analysis confirmed younger age, female gender, duration of surgery, preoperative chronic pain, type of surgery, and higher LEUK values > 11.3 as independent factors for postoperative pain. Perioperative antibiotics had no effect on the postoperative pain. CONCLUSION: Beyond known factors, preoperative LEUK as inflammation marker is an independent predictor for pain on the first postoperative day.

High-resolution MRI of the human palatine tonsil and its schematic anatomic 3D reconstruction.

The palatine tonsils form an important part of the human immune system. Together with the other lymphoid tonsils of Waldeyer's tonsillar ring, they act as the first line of defense against ingested or inhaled pathogens. Although histologically stained sections of the palatine tonsil are widely available, they represent the tissue only in two dimensions and do not provide reference to three-dimensional space. Such a representation of a tonsillar specimen based on imaging data as a 3D anatomical reconstruction is lacking both in scientific publications and especially in textbooks. As a first step in this direction, the objective of the present work was to image a resected tonsil specimen with high spatial resolution in a 9.4 T small-bore pre-clinical MRI and to combine these data with data from the completely sectioned and H&E stained same palatine tonsil. Based on the information from both image modalities, a 3D anatomical sketch was drawn by a scientific graphic artist. In perspective, such studies could help to overcome the difficulty of capturing the spatial extent and arrangement of anatomical structures from 2D images and to establish a link between three-dimensional anatomical preparations and two-dimensional sections or illustrations, as they have been found so far in common textbooks and anatomical atlases.

Non-idiopathic peripheral facial palsy: prognostic factors for outcome.

OBJECTIVES: There is a lack of data on patients' and diagnostic factors for prognostication of complete recovery in patients with non-idiopathic peripheral facial palsy (FP). METHODS: Cohort register-based study of 264 patients with non-idiopathic peripheral FP and uniform diagnostics and standardized treatment in a university hospital from 2007 to 2017 (47% female, median age: 57 years). Clinical data, facial grading, electrodiagnostics, motor function tests, non-motor function tests, and onset of prednisolone therapy were assessed for their impact on the probability of complete recovery using univariable and multivariable statistics. RESULTS: The most frequent reason for a non-idiopathic peripheral FP was a reactivation of Varicella Zoster Virus (VZV; 36.4%). Traumatic origin had a higher proportion of complete FP (52.9%). Furthermore, in traumatic FP, the mean interval between onset and start of prednisolone therapy was longer than in other cases (5.6 ± 6.2 days). Patients with reactivation of VZV, Lyme disease or otogenic FP had a significant higher recovery rate (p = 0.002, p < 0.0001, p = 0.018, respectively), whereas patients with post-surgery FP and other reasons had a significant lower recovery rate (p < 0.0001). After multivariate analyses voluntary activity in first EMG, Lyme disease and post-surgery cause were identified as independent diagnostic and prognostic factors on the probability of complete recovery (all p < 0.05). CONCLUSION: Infectious causes for non-idiopathic FP like VZV reactivation and Lyme disease had best probability for complete recovery. Post-surgery FP had a worse prognosis. LEVEL OF EVIDENCE: 2.

Ratings of Emotional Expressions in Static and Dynamic Facial Recordings Before and After Upper Face Botulinum Injections-An Observational Prospective Study.

BACKGROUND: Botulinum toxin A (BTX), a neurotoxin widely used for facial aesthetics, causes dose-dependent muscle paralysis. It was hypothesized that treatment of mimic muscles with BTX might have a positive impact on emotional expression in static images (photographs), but a negative impact in dynamic recordings (videos). OBJECTIVES: The aim of this study was to compare of emotional expression recorded in photographs and videos before and after treatment with BTX. METHODS: Twenty healthy women (mean age, 45 years) received a dose of 19 mouse units of XEOMIN (Merz, Frankfurt am Main, Germany) into the procerus, occipitofrontalis, and orbicularis oculi muscles. Photographs and videos of the participants' faces with neutral and happy expressions were recorded before treatment and 2 weeks later. Recordings were rated by naive raters blind to the conditions and in balanced order. RESULTS: Videos were generally rated as more pleasant, arousing, attractive, and genuine than photographs (all Ps > 0.001). This was especially the case for videos with neutral expression (P = 0.003). Independent of presentation mode and facial expression, women were rated as more attractive after BTX treatment (P = 0.03). CONCLUSIONS: In contrast to the hypothesis, the reduced mobility had no detectable negative impact on dynamic emotional expression, but videos received more positive ratings, particularly for neutral expressions. It is thus recommended to assess emotional expression with dynamic recordings to evaluate the effects of treatment with BTX. BTX seems to improve perceived attractiveness, although the cause of this effect remains unclear.

Riboswitching with ciprofloxacin-development and characterization of a novel RNA regulator.

RNA molecules play important and diverse regulatory roles in the cell. Inspired by this natural versatility, RNA devices are increasingly important for many synthetic biology applications, e.g. optimizing engineered metabolic pathways, gene therapeutics or building up complex logical units. A major advantage of RNA is the possibility of de novo design of RNA-based sensing domains via an in vitro selection process (SELEX). Here, we describe development of a novel ciprofloxacin-responsive riboswitch by in vitro selection and next-generation sequencing-guided cellular screening. The riboswitch recognizes the small molecule drug ciprofloxacin with a KD in the low nanomolar range and adopts a pseudoknot fold stabilized by ligand binding. It efficiently interferes with gene expression both in lower and higher eukaryotes. By controlling an auxotrophy marker and a resistance gene, respectively, we demonstrate efficient, scalable and programmable control of cellular survival in yeast. The applied strategy for the development of the ciprofloxacin riboswitch is easily transferrable to any small molecule target of choice and will thus broaden the spectrum of RNA regulators considerably.

Prognostic factors for the outcome of Bells' palsy: A cohort register-based study.

OBJECTIVES: There is a lack of data on patients' and diagnostic factors for prognostication of complete recovery in patients with Bell's palsy. DESIGN AND SETTING: Cohort register-based study of 368 patients with Bell's palsy and uniform diagnostics and standardised treatment in a university hospital from 2007 to 2017 (49% female, median age: 51 years). MAIN OUTCOME MEASURES: Clinical data, facial grading, electrodiagnostics, motor function tests, non-motor function tests and onset of prednisolone therapy were assessed for their impact on the probability of complete recovery using univariable and multivariable statistics. RESULTS: Median onset of treatment was 1.5 days. 46% of patients had a House-Brackmann scale at baseline of ≥ III. The median recovery time was 2.6 months (95% confidence interval [CI] = 2.1-3.0). 54.9% achieved a complete recovery. If prednisolone therapy started later than 96 hours after onset, the recovery rate decreased significantly. Beyond less severe palsy, no abnormal electroneurography side difference, no pathological spontaneous activity in electromyography and normal stapedius reflex testing were the most powerful tool for prognostication of recovery after Bell's palsy. CONCLUSION: Beyond severity of the palsy, facial electrodiagnostics and stapedius reflex testing are the most powerful tool for prognostication of recovery time after Bell's palsy. Prednisolone therapy should have started at best within a time window of 96 hours after onset to reach the highest probability of complete recovery.

[Current Consideration of Tonsillectomy and Tonsillotomy]. / Aktuelle Betrachtung der Tonsillektomie und Tonsillotomie.

What is right? Tonsillotomy or tonsillectomy? Moreover, when and what has to be preferred? Is the discussion never ending? No, and this is good. Tonsil surgery is and will remain a frequent surgical procedure for the otolaryngologist. Especially, because many children are operated, and because - also rare - significant complications can occur, a quality-controlled benefit-risk-analysis is important. Part of this is systematic analysis of the evidence of the benefits and risks of tonsillotomy and tonsillectomy, as it was performed recently by the Institute for Quality and Efficiency in Health Care (Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen, IQWiG) by order of the Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA). One result was the implementation of the tonsillotomy as a regular service paid by the insurance companies. Nevertheless, the discussion is not yet concluded. Actually, a randomized controlled trial is in preparation sponsored by the G-BA to proof the non-inferiority of tonsillotomy against tonsillectomy for the treatment of patients with recurrent acute tonsillitis. The present article on ENT specialist knowledge should put the reader, especially ENT residents, in a position to advice patients and their relatives on the pros and cons of tonsil surgery.

Inpatient treatment of patients with idiopathic sudden sensorineural hearing loss: a population-based healthcare research study.

PURPOSE: The aim was to determine inpatient treatment rates of idiopathic sudden sensorineural hearing loss (ISSNHL) with focus on diagnostics, treatment, and outcome. METHODS: A retrospective population-based study in the federal state Thuringia in 2011 and 2012 was performed on all 490 inpatients (51% females, median age: 60 years) treated for ISSNHL (Median duration: 7 days). The association between analyzed parameters and the probability of recovery was tested using univariable and multivariable statistics. RESULTS: The inpatient treatment rate for ISSNHL was 11.23 per 100,000. 172 patients (35%) had an outpatient treatment prior to inpatient treatment. For pure-tone audiometry of the three most affected frequencies (3PTAmax), the initial median hearing loss was 66.67 dB, the median absolute hearing gain ΔPTAabs was 10.0 dB, and the median relative hearing gain in relation with the contralateral side ΔPTArel contral was 30.86%. 51% of the patients reached a ΔPTAabs of ≥ 10 dB. About 2 of 5 patients recovered to a ΔPTArel contral ≥ 50% or reached ≤ 10 dB of contralateral ear. The multivariate analysis revealed that an ISSNHL on the left side [Hazard ratio (HR) = 1.6.88; confidence interval (CI) = 1.161-2.454], no down-sloping audiogram type (HR = 2.016; CI = 1.391-2.921), and no prior outpatient prednisolone treatment (HR = 2.374; CI = 1.505-3.745) were independent factors associated with better recovery (ΔPTAabs ≥ 10 dB). CONCLUSION: Inpatient treatment of ISSNHL is variable in daily practice. The population-based recovery rate was worse than reported in clinical trials. More standardization and clearer criteria for outpatient, inpatient, and salvage therapy are needed.

[Influence of a structured follow-up on CPAP adherence in patients with an OSAS]. / Einfluss einer strukturierten Nachsorge auf die Therapietreue bei OSAS-Patienten unter CPAP-Therapie.

OBJECTIVE: Continuous positive airway pressure (CPAP) therapy is the reference therapy for moderate and severe obstructive sleep apnea syndrome (OSAS). However, CPAP adherence is dissatisfying. We analyzed influencing factors on CPAP adherence and we evaluated if a structured follow-up enhances its adherence. MATERIAL AND METHODS: In this study all patients (n = 237) with a newly adjusted CPAP therapy due to the diagnosis of mild to severe OSAS between 2011 and 2013 were investigated. Follow-up took place every 1593.7 ± 77.4 CPAP operation hours. RESULTS: AHI (Apnea-hypopnea index) decreased significantly during therapy (5.6 ± 8.5/h; p < 0.001). 79 % fulfilled the criteria of CPAP adherence (at least 4 operation hours at 7 days a week). There were no significant influences on CPAP adherence seen in patients' demographic, clinical and pharmacological characteristics. The most common problems of patients receiving a CPAP therapy were dryness of the mucous membranes (43.7 %) and pressure marks (22.4 %). Considering the changes in Epworth Sleepiness Scale there were no significant relations to CPAP adherence. Satisfaction with our follow-up significantly correlated with CPAP adherence (r = 0.185; p = 0.032), whereas therapy pressure did not have any significant influence on CPAP adherence (r = -0.072; p = 0.383). CONCLUSION: A structured and individually adapted follow-up is important. In future, apart from control of therapy success, greater attention in the follow-up of CPAP therapy should be given to aspects of problem solution, feedback, education, and motivation.

Comparison of old (75-79 years) to very old (80+ years) hospitalized otorhinolaryngology patients.

BACKGROUND: The aim was to determine the patients' characteristics, comorbidity, and inpatient treatment features of very old otorhinolaryngology patients (80+ years) compared to old patients (75-79 years). METHODS: A single-center cohort study in a tertiary and university care center was performed with 144 old and 143 very old patients who were hospitalized in 2012. Predictors for differences between old and very old patients were analyzed univariately and multivariately using regression models. RESULTS: Ear (30 %) and nose/paranasal sinus (23 %) diseases were the most frequent reasons for hospitalization. Baseline and disease characteristics were not different between the two groups of elderly patients. Duration of hospitalization was no longer in very old patients (p = 0.827). Mobility (p = 0.017), dietary intake (p = 0.017), and having hearing aid (p < 0.0001) were independent comorbidity predictors in very old patients compared to old patients. Polymedication was found less frequently in very old patients (p = 0.017). To take cardiovascular drugs (p = 0.009) or psychotherapeutic drugs (p = 0.045) were independent permanent medication predictors in very old patients compared to old patients. About half of the patients received a surgical treatment (52 %) and the other half a conservative treatment (48 %). The very old patients received significantly more often an antibiotic treatment (p < 0.0001). Complication rates for surgical cases and non-surgical cases were not different (p = 0.686 and p = 0.524, respectively). CONCLUSIONS: Although comorbidity continues to increase in hospitalized very old compared to old otorhinolaryngology patients, most of the disease, treatment and treatment related complication characteristics seem not to change significantly from old to very old patients.

Pain after pediatric otorhinolaryngologic surgery: a prospective multi-center trial.

The purpose of this study was to describe postoperative pain within the first day after pediatric otorhinolaryngologic surgery and to identify factors influencing postoperative pain. Using a prospective evaluation and a Web-based multi-center registry, children ≥4 years of age (n = 365) rated their pain using questionnaires of the project Quality Improvement in Postoperative Pain Treatment for Children including faces numeric rating scales (FNRS, 0-10) for the determination of patient's pain on ambulation and his/her maximal and minimal pain within 8 h after day case surgery or at the first postoperative day for inpatient cases. Additionally, functional interference and therapy-related side effects were assessed. Half of the children were 4 or 5 years of age. The predominant types of surgery were adenoidectomy and tonsillectomy ± ear ventilation tubes. Although analgesics were applied preoperatively, intraoperatively, in the recovery room and on ward, maximal pain within the first day after surgery reached 4.4 ± 3.3 (FNRS). Pain was highest after oral surgery, especially after tonsillectomy and nose surgery. 39% of the children reported pain interference with breathing (39%). The most frequent side effect was drowsiness (55%). Multivariate analysis revealed that maximal pain was independently associated with the non-standardized use of opioids in the recovery room, or use of non-opioid or opioids on ward. Analgesia and perioperative pain management in pediatric otorhinolaryngologic surgery seems to be highly variable. Tonsillectomy and nose surgery are very painful. After otorhinolaryngologic surgery many children seem to receive less analgesia than needed or ineffective analgesic drug regimes.

Preoperative serum pattern analysis to predict the outcome of tonsillectomy in adults with chronic tonsillitis.

The method of classification and tree analysis (CART) was used to predict the outcome of tonsillectomy for chronic tonsillitis (CHT) analyzing patterns of serological markers. In a prospective case study of 24 adult patients with CHT in comparison to 24 patients with acute peritonsillar abscess (PTA) blood samples were assessed 1 day before (T-1) and 3 days after tonsillectomy. Outcome 6 months later (T180) was documented using the Glasgow Benefit Inventory (GBI) and the Specific Benefits from Tonsillectomy Inventory (SBTI). In comparison to PTA, patients with CHT were at best classified by C-reactive protein with a cut-off value of <16.735 mg/dl. For CHT, immunoglobulin E ≤ 144.65 kU/l and the combination of monocytes ≤ 0.565 Gpt/l plus leucocytes >5.855 Gpt/l at T-1 were the best classificators for higher SBTI overall score and symptom score symptom score, respectively, at T180. A higher benefit subscore at T180 was associated to γ-globulin >15.85 % plus α2-globulin >8.950% at T-1. The best classificator for better GBI overall score at T180 was an ASL titer >169.0 IU/ml or the combination of an ASL titer ≤ 169.0 IU/ml with lymphocytes ≤ 2.195 Gpt/l. Lymphocytes ≤ 2.195 Gpt/l were associated with higher GBI general subscore. Leukocytes ≤ 6.780 Gpt/l were related to higher GBI social support subscore. The combination of immunoglobulin A >1.360 g/l with procalcitonin level >0.058 ng/ml was the best combination to classify for higher physical health score. Instead of looking on isolated serologic markers, CART of multiple parameters seems to be more effective to predict the outcome of tonsillectomy for CHT.

[Differential diagnosis of headaches]. / Differenzialdiagnostik des Kopfschmerzes.

Headache is a frequent symptom in otorhinolaryngology. Such a secondary headache is typically caused by an organic disease in the head and neck area. Much more frequent is primary headache i.e. that an organic cause cannot be found. The most frequent primary headache types are migraine, tension-type headache, and cluster headache. What has to be done when the otorhinolaryngologist cannot find a cause for a headache in the head and neck area? This continuing education article should enable the otorhinolaryngologist to perform a first differential diagnostic exploration. Often a detailed inquiry of the patient's history and a clinical examination are sufficient to decide to which other medical discipline the patient should be referred. Furthermore, the article should enable the reader to capture red flag symptoms, i.e. to catch symptoms accompanying the headache that might be related to underlying and life-threatening disease.
