Is COVID-19 to Blame for Sensorineural Hearing Deterioration? A Pre/Post COVID-19 Hearing Evaluation Study

Our study aimed to evaluate the associations between COVID-19 infection and deterioration in sensorineural hearing thresholds among a cohort of patients from Meuhedet healthcare services (the third largest of four public healthcare provider organizations in Israel) that had undergone hearing evaluations pre- and post-COVID-19. Our findings suggest that COVID-19 does not appear to be associated with deterioration of the sensorineural hearing among unvaccinated patients who had known hearing loss pre-infection, after correcting for age-related hearing loss. Moreover, our findings do not validate previous reports of a greater deterioration in the hearing of infected patients who possess background risk factors such as smoking, hypertension, and diabetes, suggesting no interaction between risk factors and hearing deterioration post-infection.


Objectives

Here, we aimed to (a) determine whether a clinically significant sensorineural hearing loss (SNHL) change could be detected in post-coronavirus disease (COVID-19) hearing levels on comparing them with pre-infection hearing levels after controlling for the effect of age and (b) to identify risk factors, such as hypertension, diabetes, and smoking, which increase the likelihood of hearing loss in COVID-19 patients.

Methods

We retrospectively analyzed hearing thresholds in unvaccinated patient's pre- and post-COVID-19 infection. Thresholds were controlled for age and the duration between the pre- and post-COVID-19 hearing evaluations. Correlations between additional COVID-19-related symptoms, hypertension, diabetes, and smoking and hearing threshold changes were analyzed.

Results

A significant (but not clinical) threshold elevation was found post-COVID-19 infection. However, on controlling for age and the duration between the pre- and post-COVID-19 hearing evaluations, no significant threshold elevation was found. No significant correlation was found between hearing threshold changes and additional COVID-19-related symptoms, hypertension, diabetes, or smoking.

Conclusion

COVID-19 did not lead to a significant hearing threshold elevation in our cohort, even among patients with additional COVID-19 symptoms, hypertension, or diabetes mellitus or among those who smoked.

Incidence of Sinus Inflammation After Endoscopic Skull Base Surgery in the Pediatric Population

The extended endonasal approach has been utilized in the resection of anterior skull base lesions in the pediatric population. There are unique challenges to these patients in the post-operative setting, including patient compliance with medical therapy and post-operative debridements, and a smaller nasal airway that may increase propensity towards scarring. Our objective for this study is to evaluate the incidence of post-operative radiographic inflammation in this patient population using the Lund-Mackay (LM) score.


Background

The extended endonasal approach has been utilized in the resection of anterior skull base lesions in the pediatric population. There are unique challenges to these patients in the post-operative setting, including patient compliance with medical therapy and post-operative debridements, and a smaller nasal airway that may increase propensity toward scarring. Our objective for this study is to evaluate the incidence of post-operative radiographic inflammation in this patient population using the Lund-Mackay (LM) score.

Methods

A single-center, retrospective review of pediatric patients undergoing endoscopic approach to the skull base between 2009 and 2021 was performed. Demographic and clinicopathologic data and pre- and post-operative imaging were analyzed. One-way ANOVA followed by Tukey multiple pairwise comparisons statistical tests were used to compare mean LM scores between groups.

Results

Seventy-two patients (52 males, 20 females) were identified with a median follow-up of 27 months. All patients underwent an extended endonasal approach for resection of skull base lesions. The mean LM scores were compared between pre-operative MRI, first post-operative MRI > 30 days after surgery, and most recent post-operative MRI. One-way ANOVA was performed with significant differences noted between the groups (p < 0.001). Tukey multiple pairwise comparisons test was then performed and noted significant differences between the pre-operative and first post-operative LM (p < 0.0001) and the first post-operative and most recent LM (p < 0.0001). There was no significant difference noted between the pre-operative LM score and most recent LM score (p = 0.14).

Conclusion

Despite concerns regarding possible subsequent development of chronic rhinosinusitis following endoscopic skull base surgery in pediatric patients, the current study suggests that transient radiographic evidence of sinus inflammation can be seen up to six months postoperatively, which appears to resolve by approximately two years after surgery.

Impact of respiratory infection and chronic comorbidities on early pediatric antibiotic dispensing in the United States

alexandrossfakianakis shared this article with you from Inoreader
Abstract
Background
In the United States, children under age 5 receive high volumes of antibiotics, which may contribute to antibiotic resistance. It has been unclear what role preventable illnesses and chronic comorbidities play in prompting antibiotic prescriptions.
Methods
We conducted an observational study with a cohort of 124,759 children under age 5 born in the United States between 2008 and 2013 with private medical insurance. Study outcomes included the cumulative number of antibiotic courses dispensed per child by age 5 and the proportion of children for whom at least one antibiotic course was dispensed by age 5. We identified which chronic medical conditions predicted whether a child would be among the top 20% of antibiotic recipients.
Results
Children received a mean of 6.8 (95% confidence interval [CI] 6.7, 6.9) antibiotic courses by age five, and 91% (95% CI 90, 92) of children had received at least one antibiotic course by age five. Most antibiotic courses (71%, 95% CI 70, 72) were associated with respiratory infections. Presence of a pulmonary/respiratory, otologic, and/or immunological comorbidity substantially increase a child's odds of being in the top 20% of antibiotic recipients. Children with at least one of these conditions received a mean of 10.5 (95% CI 10.4, 10.6) antibiotic courses by age 5.
Conclusions
Privately insured children in the US receive high volumes of antibiotics early in their lives, largely related to respiratory infections. Antibiotic dispensing is unequally distributed among children, with substantially more antibiotics dispensed to children with select comorbidities.

Booster vaccination against SARS-CoV-2 induces potent immune responses in people with HIV

alexandrossfakianakis shared this article with you from Inoreader
Abstract
Background
People with HIV on antiretroviral therapy with good CD4 T cell counts make effective immune responses following vaccination against SARS-CoV-2. There are few data on longer term responses and the impact of a booster dose.
Methods
Adults with HIV were enrolled into a single arm open label study. Two doses of ChAdOx1 nCoV-19 were followed twelve months later by a third heterologous vaccine dose. Participants had undetectable viraemia on ART and CD4 counts >350 cells/µl. Immune responses to the ancestral strain and variants of concern were measured by anti-spike IgG ELISA, MesoScale Discovery (MSD) anti-spike platform, ACE-2 inhibition, Activation Induced Marker (AIM) assay and T cell proliferation.
Findings
54 participants received two doses of ChAdOx1 nCoV-19. 43 received a third dose (42 with BNT162b2; 1 with mRNA-1273) one year after the first dose. After the third dose, total anti-SARS-CoV-2 spike IgG titres (MSD), ACE-2 inhibition and IgG ELISA results were significantly higher compared to Day 182 titres (P < 0.0001 for all three). SARS-CoV-2 specific CD4+ T cell responses measured by AIM against SARS-CoV-2 S1 and S2 peptide pools were significantly increased after a third vaccine compared to 6 months after a first dose, with significant increases in proliferative CD4 + and CD8+ T cell responses to SARS-CoV-2 S1 and S2 after boosting. Responses to Alpha, Beta, Gamma, and Delta variants were boosted, although to a lesser extent for Omicron.
Conclusions
In PWH receiving a third vaccine dose, there were significant increases in B and T cell immunity, including to known VOCs.

Role of sentinel lymph node biopsy for oral squamous cell carcinoma: Current evidence and future challenges

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Sentinel lymph node biopsy (SLNB) has been used across oncological specialties for prognostication, staging, and identification of occult nodal metastasis. Recent studies demonstrated the potential clinical utility of SLNB in oral cavity squamous cell carcinoma (OCSCC). Elective neck dissection is the current standard of care in early management of OCSCC with depth of invasion greater than 2–4 mm; however, majority of patients ultimately do not have nodal disease on final pathology. SLNB is an alternative procedure widely adopted in early cancer management in many oncological subspecialities. Several considerations such as depth of invasion, nodal mapping, histopathology methods, operator variability, postoperative complications, and advancement in preoperative and intraoperative imaging technology can guide the appropriate application to SLNB in OCSCC. The aim of this review is to discuss the current evidence for SLNB in the treatment of early stage OCSCC, imaging technologie s that support SLNB procedures, and studies that are currently underway.

Irinotecan dose schedule for the treatment of Ewing sarcoma

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Irinotecan and temozolomide achieve objective responses in patients with Ewing sarcoma that recurs after initial therapy. Optimal dose schedules have not been defined. We reviewed published series of patients treated with irinotecan and temozolomide for Ewing sarcoma that recurred after initial therapy. We compared objective response rates for patients who received 5-day irinotecan treatment schedules to response rates for patients who achieved 10-day irinotecan treatment schedules. Among 89 patients treated with a 10-day irinotecan schedule, there were 47 objective responses (53%). Among 180 patients treated with a 5-day irinotecan schedule, there were 52 responses (29%). In the treatment of recurrent Ewing sarcoma, investigators should consider the use of a 10-day schedule for administration of irinotecan.

Relationship between the timing of chemotherapy and surgical complications following surgical biopsy in children with malignant solid tumors

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Biopsies for diagnosis before chemotherapy is common in children with malignant solid tumors. Wound healing is delayed by chemotherapy; however, the ideal interval between biopsy and chemotherapy remains unknown. We aimed to summarize the relationship between chemotherapy timing and postoperative surgical complications.

Procedure

We retrospectively reviewed patients with malignant solid tumors who underwent chemotherapy after surgical biopsy at our institution between January 2014 and August 2020. The primary outcomes were postoperative surgical complications (within 30 days) and the timing of chemotherapy.

Results

Forty-three patients were analyzed. The types of tumors were neuroblastoma (n = 20), hepatoblastoma (n = 10), Ewing sarcoma (n = 5), germ cell tumor (n = 3), angiosarcoma (n = 1), clear cell sarcoma (n = 1), ganglioneuroblastoma (n = 1), rhabdoid tumor (n = 1), and rhabdomyosarcoma (n = 1). The operative procedures were thoracoscopy (n = 5), laparotomy (n = 17), laparoscopy (n = 14), and superficial (n = 7). The median time [range] to chemotherapy after biopsy was 4 [0–21] days. No surgical complications occurred before chemotherapy, and two (4.7%) patients experienced complications after chemotherapy. These included postoperative hemorrhage (grade 3) and surgical site infection (grade 1). Chemotherapy was initiated 1 and 6 days after biopsy, respectively, in these cases. Complications occurred 10 and 23 days after biopsy, respectively.

Conclusion

The rate of postoperative surgical complications related to biopsy seems acceptable, even when chemotherapy was initiated in the early postoperative period. Early initiation of chemotherapy after biopsy may be a suitable option, particularly in children with bulky or symptomatic malignant solid tumors.

Imaging of pediatric testicular tumors: A COG Diagnostic Imaging Committee/SPR Oncology Committee White Paper

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Primary intratesticular tumors are uncommon in children, but incidence and risk of malignancy both sharply increase during adolescence. Ultrasound is the mainstay for imaging the primary lesion, and cross-sectional modalities are often required for evaluation of regional or distant disease. However, variations to this approach are dictated by additional clinical and imaging nuances. This paper offers consensus recommendations for imaging of pediatric patients with a known or suspected primary testicular malignancy at diagnosis and during follow-up.
