Ethical implications of COVID-19 management-is freedom a desired aim, or a desired means to an end?

Most developed societies managed, due to their prosperity and resource abundance, to structure relationships among free individuals in such a way to leave them fundamentally unstructured, according to the free market principle. As the pandemic illustrated well, this lack of structure when facing collective threats makes it impossible to collectively and proportionately assess and manage its implications and consequences. This may be particularly precarious when introducing comprehensive, monitoring and tracking, surveillance systems dependent on the vaccination status of the individual. If our previously shared aims were successfully and collectively enacted with the greatest of costs, is it permissible that the degree of personal freedom is a commodity, and everyone is a compulsory participant? The need to control one's COVID-19 status allows the individual to become legally free from excessive enactment of sovereignty of the state. Should these rights be regulated by the free market?

The Relationship between Tumor Budding and Tumor Deposits in Patients with Stage III Colorectal Carcinoma.

Background/Objectives: Recently, some new morphological features of colorectal cancer have been discovered as important prognostic factors; in this paper, we study the relationship between tumor budding (TB) and tumor deposits (TDs). Methods: The retrospective cohort study included 90 patients with pathohistologically confirmed stage III CRC who were treated with radical surgical resection. All hematoxylin and eosin (H and E)-stained slides from each patient were reviewed, and histological parameters were recorded. The samples were divided into two groups with similar sizes: a group without TDs (N = 51) and a control group with TDs (N = 39). The presence and TB grade were further analyzed in these groups and compared with other clinical and histological features. Results: The prevalence of TB in the investigated cohort was unexpectedly high (94.4%). Overall, there were 23 (25.6%) Bd1, 20 (22.2%) Bd2, and 47 (52.2%) Bd3 cases. The presence of TDs was significantly associated with a higher number of TB (p < 0.001, OR 16.3) and, consequently, with a higher TB grade (p = 0.004, OR 11.04). A higher TB grade (p = 0.001, HR 2.28; 95% CI 1.93-4.76) and a growing number of TDs (p = 0.014, HR 1.52; 95% CI 1.09-2.1) were statistically significantly associated with shorter survival. Conclusions: TDs appear more often in patients with higher TB grades in stage III CRC. A higher TB grade and a growing number of TDs were statistically significantly associated with shorter overall survival. These results could give additional emphasis to the importance of TB as an adverse prognostic factor since a strong relationship with TDs has been demonstrated.

Impact Of Sensorineural Hearing Loss On Subjective Tinnitus Quality In Patients With Bilateral Tinnitus.

INTRODUCTION: Tinnitus is a frequent condition that indicates the sensation of sound in the absence of a corresponding external stimulus and can significantly impair the quality of life. The main risk factor for developing tinnitus is hearing loss. The diagnosis of tinnitus is based on history, assessment of tinnitus severity, clinical examination, and audiological tests. The main purpose of this research was to examine the relationship between the presence and level of hearing loss and the characteristics of tinnitus in patients with bilateral subjective tinnitus. METHODS: Total number of 50 participants, 20 men, and 30 women were included in the research. Demographic data, data on hearing impairment obtained by tone audiometry, and data on difficulties caused by tinnitus obtained in two questionnaires - Tinnitus Handicap Inventory (THI) and Tinnitus Functional Index (TFI) were used. RESULTS: Age above 30 years is significantly associated with tinnitus with hearing loss. Hearing impairment is also significantly more often associated with an auditory TFI index >6.7, a total THI index >20, and an emotional THI index >3. Hearing loss was noted in 76% of patients. CONCLUSION: Tinnitus represents a significant burden for patients, therefore it is important to assess the impact of tinnitus on daily activities and quality of life.

Assessing Symptomatic Hypocalcemia Risk After Total Thyroidectomy: A Prospective Study.

Introduction The most common postoperative complication of total thyroidectomy is hypocalcemia, usually monitored using serum parathyroid hormone and calcium values. Objective To identify the most accurate predictors of hypocalcemia, construct a risk assesment algorithm and analyze the impact of using several calcium correction formulas in practice. Methods A prospective, single-center, non-randomized longitudinal cohort study on 205 patients undergoing total thyroidectomy. Parathyroid hormone, serum, and ionized calcium were sampled post-surgery, with the presence of symptomatic or laboratory-verified asymptomatic hypocalcemia designated as primary outcome measures. Results Parathyroid hormone sampled on the first postoperative day was the most sensitive predictor of symptomatic hypocalcemia development (sensitivity 80.22%, cut-off value ≤2.03 pmol/L). A combination of serum calcium and parathyroid concentration sampled on the first postoperative day predicted the development of hypocalcemia during recovery with the highest sensitivity and specificity (94% sensitivity, cut-off ≤2.1 mmol/L, and 89% specificity, cut-off ≤1.55 pmol/L, respectively). The use of algorithms and correction formulas did not improve the accuracy of predicting symptomatic or asymptomatic hypocalcemia. Conclusions The most sensitive predictor of symptomatic hypocalcemia present on the fifth postoperative day was PTH sampled on the first postoperative day. The need for algorithms and correction formulas is limited.

Systematic Review of Current Audiological Treatment Options for Patients with Treacher Collins Syndrome (TCS) and Surgical and Audiological Experiences of an Otorhinolaryngologist with TCS.

Treacher Collins syndrome (TCS) is a rare congenital craniofacial condition that affects approximately one out of fifty thousand births. Different ratios of TCS patients have conductive hearing loss: 88%1 vs. 91.4-100.00%2. For this reason, it was examined which hearing solutions can be used with this condition and how effective they are. A systematic literature review was conducted, which showed that the bone-anchored hearing aid (BAHA, OSIA), the bone conduction implant (Bonebridge) or the active implant of the middle ear (Soundbridge) are reliable methods for the treatment of conductive hearing loss in TCS patients. After the implantation of all available hearing solutions, improved hearing and speech comprehension were observed. Additionally, a statement regarding the treatment of TCS and a personalized point of view of a clinical expert with TCS were provided. However, due to the small amount of data, no general recommendations can be given for the treatment of hearing loss in TCS patients; therefore, it is advised to collect more data on hearing solutions for TCS patients in future research.

Management of Implant Extrusion following Thyroplasty for Vocal Fold Paralysis: A Case Report.

The most widely used laryngeal surgery technique for patients with vocal fold paralysis is medialization thyroplasty. Materials such as Gore-Tex, silastic, and hydroxyapatite are often used, and the most worrisome possible complication is extrusion of the implant. A 36-year-old female patient with a history of pediatric cardiac surgery was diagnosed with left vocal cord paralysis after an episode of upper respiratory infection with a working diagnosis of subclinical left vocal cord paralysis following cardiac surgery. She underwent medialization thyroplasty with a Gore-Tex implant under local anesthesia. On the 21st postoperative day, she presented with sudden-onset hoarseness and dysphagia due to Gore-Tex implant extrusion. The implant was removed and augmentation of the left vocal cord with adipose tissue was performed. Only 14 cases of Gore-Tex implant extrusion have been described in the literature so far. The aim of this case report was not only to show one possible complication when using a Gore-Tex implant but also to present fat augmentation as one of the solutions for revision medialization and salvage treatment, with sustained long-term results.

Dedifferentiated Primary Parosteal Osteosarcoma of the Temporal Bone in a 19-Year-Old Patient: A Case Report.

Osteosarcoma is the most common primary malignant tumor affecting the bone but is a rare occurrence in the head and neck region. Complete surgical resection with wide surgical margins is currently the main treatment strategy for osteosarcoma but can be hard to achieve due to the complex anatomy of the head and neck. We report the first case of primary high-grade dedifferentiated parosteal osteosarcoma arising from the temporal bone in published literature. The 19-year-old patient presented with a left retroauricular lesion measuring 3 cm in diameter. Radiographic imaging and biopsy suggested the diagnosis of intermediate-grade chondrosarcoma, but definitive histopathology confirmed a diagnosis of dedifferentiated parosteal osteosarcoma. The tumor was resected with wide margins, removing the underlying temporal bone, periosteum and overlying soft tissue through a lateral temporal bone resection. The middle ear was reconstructed with cartilage grafting, and the dura of the posterior and middle cranial fossa was covered using temporal fascia grafts and local transpositional flaps. The patient is recurrence free 10 months after treatment. This report was assembled following CARE [The CARE guidelines (for Case Reports)] guidelines and describes clinical, histological, and radiological manifestations of our patient's rare clinical entity and may provide more data in treating patients with osteosarcoma affecting the anatomically complex head-and-neck region.

Auditory Brainsteam Response Testing in Children with Speech and Language Pathology: A Non-Randomized Observational Study.

INTRODUCTION: The aim of this study was to compare ABR findings of normal hearing preschool children with different types of speech and language pathology. METHODS: This retrospective, non-randomized, cohort study was conducted at a tertiary speech and hearing rehabilitation institution according to STROBE guidelines. The study enrolled 123 preschool children diagnosed with speech language pathology and normal hearing. The participants included children with developmental language disorder, autism spectrum disorder, isolated articulation pathology, organic brain lesions, cognitive delay and a group of very young children with clinically significant speech development delay. All patients underwent standard ABR procedures. RESULTS: The latencies were the longest in the group of children with organic lesion, followed by the group of children with ASD, then the group with DLD, and the young children group. In the group of children with articulation pathology and the cognitive delay group, the latencies were the shortest. DISCUSSION/CONCLUSION: This study showed a connection between several groups of children with language pathology that include comprehension problems and prolongation of ABR latencies.

In search of new stratification strategies: tissue proteomic profiling of papillary thyroid microcarcinoma in patients with localized disease and lateral neck metastases.

INTRODUCTION: Papillary thyroid carcinomas (PTC) are the most common thyroid malignancies that are often diagnosed as microcarcinomas when the tumor is less than one centimetre in diameter. Currently, there are no valid stratification strategies that would reliably assess the risk of lateral neck metastases and optimize surgical treatment. MATERIALS AND METHODS: Aiming to find potential tissue biomarkers of metastatic potential, we conducted a cross-sectional proteomic pilot study on formalin-fixed paraffin-embedded tissues of metastatic (N = 10) and non-metastatic (N = 10) papillary thyroid microcarcinoma patients. Samples were analysed individually using liquid chromatography/mass spectrometry, and the differentially expressed proteins (DEP) were functionally annotated. RESULTS: We identified five overexpressed DEPs in the metastatic group (EPB41L2, CSE1L, GLIPR2, FGA and FGG) with a known association to tumour biology. Using bioinformatic-based tools, we found markedly different profiles of significantly enriched biological processes between the two groups. CONCLUSIONS: The identified DEPs might have a role as potential tissue biomarkers for PTC metastases. However, further prospective research is needed to confirm our findings.

Wearing masks to prevent one epidemic may mask another.

Background: With attempts at lifting most COVID-19 pandemic-related restrictions, other common respiratory viruses have caused more health concern than in earlier seasons in pediatric populations. Objective: To explore the role of non-pharmaceutical interventions (NPIs) in a rebound in other respiratory viral pathogens, especially in light of general vaccination fatigue, COVID-19 boosters, and operational challenges in the healthcare system. Methods: A research-based commentary supported with recent literature review. Findings: Pandemic-related lockdowns in Europe, Australia, and New Zealand have created a significant population of susceptible young children without preexisting immunity due to lack of exposure during the colder months. Relying on NPIs for a prolonged period due to low vaccination rates may lead to increased respiratory infection susceptibility, especially among young children less than 5 years old. The key public health question is whether NPIs should be implemented in the long run and what are the long-term implications on the dynamics of endemic infections and population immunity. Discussion: Prevention cannot be the only cure for any infectious disease, and long-term impact of NPIs depends on the dynamics of population susceptibility. The SARS-CoV-2 pandemic has reinforced the importance of vaccination and the knowledge on vaccine use combined with NPIs will be of great value in controlling other known and unknown respiratory pathogens. Combining NPIs and vaccination is paramount in disease control, and the discussion on how to prevent collateral damage to sensitive populations while relaxing NPI-related measures should also merit attention.

Impact of Intraoperative Findings on Hearing in Revision Ear Surgery.

Introduction: Hearing results after chronic ear surgery encompass recurrence, localization and extent of cholesteatoma, type of surgery, ossiculoplasty methods, but rarely interpret intraoperative findings. This study aimed to analyze the impact of intraoperative findings in revision tympanomastoidectomy in predicting postoperative hearing. Materials and Methods: This was a retrospective non-randomized cohort of 101 patients treated for recurrent chronic otitis media by tympanomastoidectomy. The patients' demographics, localizations of disease recurrence and perioperative hearing results were analyzed. Results: Logistic regression showed that presence of tympanic perforation (p=0.036), ossicular chain damage (p=0.006), were negatively associated with improved hearing postoperatively. Attic cholesteatoma was associated with better postoperative hearing (p=0.045). Presence of tympanic perforation (p=0.050), alongside perifacial localization of imflammation (p=0.021) and ossicle destruction (p=0.013) were associated with worse postoperative hearing results. Multivariate analysis confirmed that tympanic perforation (p=0.040, F=4.401), and ossicular chain involvement (p=0.025, F=5.249), were consistent negative predictors of hearing improvement, while postoperative deterioration of hearing was associated with tympanic perforation (p=0.038, F=4.465) and facial nerve dehiscence (p=0.045, F=4.160). Conclusions: Comparison of postoperative revision tympanomastoidectomy hearing outcomes revealed significant positive reductions in air-bone gap values, primarily at low and mid frequencies. Postoperative hearing results at high frequencies are not affected by revision surgery.

Surgical Considerations in Addressing Cholesterol Granuloma of the Petrous Apex through an Infracochlear Approach.

Cholesterol granuloma of the petrous bone is a foreign body giant cell reaction to cholesterol deposits with symptoms including hearing loss, vestibular dysfunction, and cranial nerve deficit as a result of cystic mass compression. Surgical treatment is often difficult to plan due to limited access to the lesion and possible injury to surrounding structures. We report on a case of petrous apex cholesterol granuloma drainage through an infracochlear approach. A 27-year-old female patient presented with acute diplopia due to left-sided abducens paralysis. Multislice computed tomography (MSCT) and magnetic resonance (MR) imaging described a 3.5-cm well-marginated lesion in petrous bone apex, compressing the left abducens nerve at the point of entry into the cavernous sinus, corresponding to cholesterol granuloma. The patients was surgically treated through a transcanal infracochlear approach, since preserving the external and middle ear conduction mechanisms was paramount for the patient. The patient was discharged on the second postoperative day and diplopia resolved within 5 days postoperatively. Six months after the surgery, her hearing on the left side is normal, and she remains symptom-free. This case underpins the value of preoperative planning when approaching the petrous apex, an anatomically complex area due to abundance of important neurovascular structures crowded in a narrow and confined region.

Comparison of Intratympanic Steroid and Hyperbaric Oxygen Salvage Therapy Hearing Outcomes in Idiopathic Sudden Sensorineural Hearing Loss: A Retrospective Study.

OBJECTIVES: Systemic steroids are the most common first-line therapy in sudden sensorineural hearing loss (SSNHL), with significant improvement in hearing outcomes in over 60% of patients. It is unknown why 40% of patients do not respond to systemic steroid therapy. Salvage treatment includes intratympanic steroids (ITS) and hyperbaric oxygenation (HBO) therapy, with inconsistent results reported. This study aimed to compare the results of ITS and HBO therapy in patients with SSNHL that previously failed systemic steroid therapy. DESIGN: This is a comparative retrospective nonrandomized interventional cohort study, enrolling 126 patients with SSNHL. Out of these, 35 patients received HBO therapy, 43 patients received ITS, and 48 patients did not receive any second-line therapy (control group). Pure-tone audiograms were performed before and after the salvage therapy in the IT and HBO groups and at the same time interval in the control group. Study variables included age, time until therapy initiation, tinnitus status, and hearing outcomes, with a cutoff criteria of cumulative >30 dB improvement on all frequencies indicating recovery. RESULTS: ITS and HBO therapy were associated with statistically significant hearing recovery at all frequencies compared to systemic steroids. The results show an average hearing improvement of 13.6 dB overall frequencies (250 to 8000 Hz) after ITS therapy and 7.4 dB in HBO therapy in comparison to the control group. Presence of significant hearing improvement positively correlated with age, ITS therapy, and HBO therapy. Presence of tinnitus before therapy was negatively correlated with hearing improvement. Patients with tinnitus present at the start of therapy improve 4.67 dB less on average compared to those without tinnitus. ITS therapy significantly reduced tinnitus compared to the other two treatment options. Patients with tinnitus present before therapy significantly improve hearing at low frequencies, compared to the control group. CONCLUSIONS: ITS and HBO therapy show superior hearing results compared to observation alone after failed oral steroid therapy for SSNHL. ITS shows an additional positive impact on tinnitus reduction and shows superior hearing outcomes after salvage therapy.

Analysis of Prognostic Factors Impacting Pediatric Acute Mastoiditis Outcomes.

BACKGROUND: This study aimed to investigate the outcomes of pediatric patients with acute mastoiditis while examining the role of intravenous steroid therapy, patient demographics, and serum inflammatory values as prognostic factors. METHODS: This study is a single-center retrospective observational study including 73 consecutive patients treated for acute mastoiditis in the course of the 10-year study period (January 2010 to December 2019). RESULTS: Data analysis showed that patients requiring surgical treatment (14%) had a 3-fold higher C-reactive protein value at admission compared to those treated conservatively (P < .001). Receiver operating characteristic analysis revealed that a C-reactive protein cut-off of ≥98.7 had a sensitivity and specificity of 100% and 74.6%, respectively, for predicting the need for surgery (area under the curve=0.927, P < .001). The duration of symptoms before hospitalization was nearly 2 days shorter in male patients (P=.031), and the use of intravenous steroid therapy significantly shortened the length of hospitalization (P=.023), by 1.4 days on average. CONCLUSION: Intravenous steroid therapy may be useful in decreasing the length of hospital stay. Mastoiditis tends to present more severely in male patients, and monitoring C-reactive protein values during treatment correlated well with the need for surgery.

Diagnostic Accuracy of Preoperative CT and Endoscopy Staging in Early Laryngeal Cancer.

OBJECTIVES: This study aims to evaluate the diagnostic accuracy of preoperative computed tomography (CT) and intraoperative endoscopic tumor staging with regard to histopathologic staging in patients with early laryngeal cancer. STUDY DESIGN: A retrospective nonrandomized single-institution comparative cohort study including 109 patients. SETTING: A tertiary surgical center. METHODS: Patients were treated for T1a, T1b, and T2a laryngeal squamous cell carcinoma by endoscopic laser surgery. The outcome measures were the presence of under- or overstaging in endoscopic and CT findings and positive postoperative margins. RESULTS: Endoscopic overstaging as compared with histopathologic T category correlated with rising tumor category (P = .001; odds ratio [OR], 69.1) and CT findings showing anterior commissure involvement (P = .002; OR, 9.54), while endoscopic understaging correlated with rising tumor histologic grade (P = .039; OR, 4.28) and smaller tumor size (P = .011; OR, 6.39). CT overstaging vs histopathologic T category correlated with CT findings showing anterior commissure involvement (P = .001; OR, 21.76), supraglottic involvement (P = .001; OR, 59.98), subglottic involvement (P = .001; OR, 39.94), rising clinical T category (P = .01; OR, 9.11), and rising tumor histologic grade (P = .004; OR, 10.95). CT understaging as compared with histopathologic T category correlated with smaller clinical T categories (P = .002; OR, 12.72) and smaller tumor histologic grade (P = .030; OR, 7.02). Rising age, rising tumor size, anterior commissure involvement on CT, and tumor extension into the supraglottis were risk factors for positive margins. CONCLUSION: Our results indicate that CT adds little valuable information in differentiating small superficial lesions in the glottis, while systematically overstaging cases of early laryngeal cancer. In T1a and T1b glottic tumors, endoscopy should be the preferred diagnostic method.

Systemic Inflammatory Markers as Predictors of Postoperative Complications and Survival in Patients With Advanced Head and Neck Squamous Cell Carcinoma Undergoing Free-Flap Reconstruction.

PURPOSE: The aim of this study was to determine the prognostic value of systemic inflammatory indices as factors for postoperative complications and survival in patients with advanced stages of p16-negative head and neck squamous cell carcinoma undergoing free-flap reconstruction. METHODS: This was a retrospective cohort study. The primary predictor variables were inflammatory markers such as neutrophil, lymphocyte, monocyte, and platelet count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio, lymphocyte-monocyte ratio, derived NLR, systemic immune-inflammatory index, and systemic inflammatory marker index (SIM). Multivariate regression analyses were used to measure the associations between systemic inflammatory indices and overall and disease-free survival as a primary outcome and occurrence of postoperative complications as a secondary outcome measure. RESULTS: The sample was composed of 69 male (76.67%) and 21 female (23.33%) patients, with an average age of 61.15 ± 9.79 years. The median follow-up time was 24 months, and 73 of 91 (66.43%) patients were alive during the median follow-up. Overall disease survival correlated with systemic immune-inflammation (P = .022, cutoff >1,005.3, sensitivity 67.1%, and specificity 70.6%) and SIM (P = .0001, cutoff >4.05, sensitivity 90.4%, and specificity 41.2%), preoperative platelets (P = .036, cutoff <194, sensitivity 28.8%, and specificity 94.1%), and postoperative lymphocytes (P = .012, cutoff <0.6, sensitivity 38%, and specificity 76.5%), whereas increased SIM (P = .042, cutoff >4.05, sensitivity 91.3%, and specificity 38.1%), NLR (P = .031, cutoff >13.2, sensitivity 56.9%, and specificity 60%), and preoperative platelets (P = .006, cutoff <244, sensitivity 52.3%, and specificity 76%) were associated with adverse disease-free survival. The cumulative postoperative complication rate was 34.5%, of which 13.3% accounted for major complications, whereas derived NLR (P = .013, degrees of freedom 1, χ2 test 6.161, cutoff >2.3) and postoperative lymphocytes (P = .009, DF 1, χ2 test 6.756, cutoff <1) correlated with occurrence of complications. CONCLUSIONS: Inflammatory indices as measures of inflammation-related systemic dysfunction may be associated with adverse survival in patients with head and neck squamous cell carcinoma and occurrence of postoperative complications and with specific cutoff values.

Chronic spontaneous urticaria and angioedema in a patient with autoimmune thyroid disease resolved after thyroidectomy.

The link between chronic urticaria and accompanying thyroid disease is still not understood, with current treatment focusing on antihistamines and levothyroxine. A 35-year-old female patient presented with chronic idiopathic urticaria and facial angioedema for 9 months prior to evaluation. Oral corticosteroid therapy, antihistamines, leukotriene-antagonists, selenium, and omalizumab were all administered, with the disease relapsing within several days, accompanied with facial angioedema of varying severity. Laboratory results were negative for antinuclear antibodies (ANA) and cytoplasmic antineutrophil antibodies (ANCA). Immunoglobulins and complement levels were normal. Autologous serum testing, and skin-prick test for common inhalatory allergens were all normal. Levothyroxine was then administered with no effect on the symptoms. After considering all of the available treatment options, the patient decided to undergo total thyroidectomy. Urticaria and angioedema subsided on the third postoperative day, and she remains free of symptom recurrence during 10 months of postoperative follow-up. Her antiTPO titer decreased from > 1300 to 31.1 kIU/L and antiTG decreased from 272 to 4.9 kIU/L three months after the surgery. The most important element in this case report is an unexpected extra-thyroid presentation of an autoimmune thyroid disease, with a newly described association with facial angioedema. Additional important evidence may confirm the hypothesis that both conditions are indeed caused by a common immunological patohogenetic pathway that should be routinely evaluated in patients presenting with chronic idiopathic urticaria.

A case study of complex disasters within the resilience framework in Zagreb, Croatia: Two earthquakes in one pandemic.

This paper is an analysis of complex crisis management and the importance of resilience on the example of co-occurring disasters. A resilience framework model was analyzed based on epidemiologic data and the interplay of several disasters; the COVID-19 pandemic and two 2020 Zagreb, Croatia earthquakes. A dose-response principle may be applied to a complex crisis scenario, within a resilience-vulnerability framework. The available data present the concept of balance between vulnerability and resilience of the population affected by complex crises as well as possible adaptation mechanisms. Multiple disasters that last for a prolonged period reduce the populations' resilience and increase the risk of the next crisis becoming a disaster as well. Such complex disasters should not be approached by multiple risk management protocols, but rather by a single, multilayered protocol. Health policies that predict the possible effects of complex disasters on health risk management need to provide measures to maintain and promote resilience instead of collapse. These is a clear need to adopt green environmental policies, reduce socioeconomic inequality, train volunteer managers during crises, introduce timely evidence-informed policies and transfer new research and innovations in society rapidly.
