Risk Factors Associated with Mortality in Patients with Mucormycosis Post Severe Acute Respiratory Syndrome Coronavirus-2 (Sars-Cov-2) Infection.

To study the potential risk factors associated with mortality in patients with mucormycosis. A retrospective study of 490 patients with diagnosis of sinonasal mucormycosis was done. They were divided in two groups-Group A included 87 patients that expired during the study period and Group B included 403 control patients. All the demographic, clinical and outcome parameters were collected from the patient's record files and noted in a structured case proforma and were analysed. During the mean hospital stay of 22 ± 6 days, 17.7% patients expired during the treatment course. Multiple risk factors like uncontrolled diabetes, dyselectrolytemia, underlying renal disease and extensive nature of the disease involving orbit, intracranium and with pulmonary dissemination, all were associated with high mortality in Mucormycosis. Early recognition and appropriate management of the secondary factors can grossly reduce the risk of mortality in patients with mucormycosis.

An Objective Comparison of the Quality and Reliability of Information Regarding Autism Spectrum Disorder on YouTube.

BACKGROUND: YouTube serves as a good source of information on autism; however, the reliability and quality of such content remain uncertain. This study aimed to evaluate the reliability and quality of autism-related information presented in YouTube videos using the Global Quality Score (GQS) and Reliability Score.  Methods: A cross-sectional observational study was conducted in November 2023. A total of 48 autism-related videos on YouTube were sourced using keywords such as 'autism', 'autism cause', 'autism treatment', and 'autism kids'. The authors then viewed the videos and collected data regarding the number of views, likes and comments, uploader type, and type of information disseminated. The authors also used The GQS and modified DISCERN score to assess the quality and reliability of information in the videos. The data was then subjected to statistical analysis using the Kruskal-Wallis test and IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States).  Results: Out of 48 videos, seven videos were excluded, leaving 41 for analysis. The included videos amassed 25,540,635 views, 304,557 likes, and 37,039 comments. The majority of videos were uploaded by hospitals (n=15; 36.59%), followed by news channels (n=12; 29.27%). Most videos described autism symptoms (n=26; 63.41%), with fewer addressing potential etiology (n=16; 39.02%). The median GQS was highest for videos uploaded by healthcare professionals (n=5), contrasting with news channels. The Kruskal-Wallis test revealed significant differences (p=0.02).  Conclusion: These videos collectively garnered substantial viewership, likes, and comments. Most videos described autism symptoms, although fewer addressed potential causes. Notably, videos uploaded by healthcare professionals achieved the highest GQSs, highlighting their significance in disseminating reliable autism information. Healthcare professionals therefore play a crucial role in disseminating reliable autism information via YouTube. Encouraging their involvement in creating informative videos can enhance public understanding of autism.

Investigating the causal interplay between sleep traits and risk of acute myocardial infarction: a Mendelian randomization study.

BACKGROUND: Few studies have investigated the joint effects of sleep traits on the risk of acute myocardial infarction (AMI). No previous study has used factorial Mendelian randomization (MR) which may reduce confounding, reverse causation, and measurement error. Thus, it is prudent to study joint effects using robust methods to propose sleep-targeted interventions which lower the risk of AMI. METHODS: The causal interplay between combinations of two sleep traits (including insomnia symptoms, sleep duration, or chronotype) on the risk of AMI was investigated using factorial MR. Genetic risk scores for each sleep trait were dichotomized at their median in UK Biobank (UKBB) and the second survey of the Trøndelag Health Study (HUNT2). A combination of two sleep traits constituting 4 groups were analyzed to estimate the risk of AMI in each group using a 2×2 factorial MR design. RESULTS: In UKBB, participants with high genetic risk for both insomnia symptoms and short sleep had the highest risk of AMI (hazard ratio (HR) 1.10; 95% confidence interval (CI) 1.03, 1.18), although there was no evidence of interaction (relative excess risk due to interaction (RERI) 0.03; 95% CI -0.07, 0.12). These estimates were less precise in HUNT2 (HR 1.02; 95% CI 0.93, 1.13), possibly due to weak instruments and/or small sample size. Participants with high genetic risk for both a morning chronotype and insomnia symptoms (HR 1.09; 95% CI 1.03, 1.17) and a morning chronotype and short sleep (HR 1.11; 95% CI 1.04, 1.19) had the highest risk of AMI in UKBB, although there was no evidence of interaction (RERI 0.03; 95% CI -0.06, 0.12; and RERI 0.05; 95% CI -0.05, 0.14, respectively). Chronotype was not available in HUNT2. CONCLUSIONS: This study reveals no interaction effects between sleep traits on the risk of AMI, but all combinations of sleep traits increased the risk of AMI except those with long sleep. This indicates that the main effects of sleep traits on AMI are likely to be independent of each other.

Isolated Frontal Sinus Mucormycosis Post Covid 19-external Approaches Revisited!

Background: Isolated frontal sinus involvement in mucormycosis is seen very infrequently. Recent technological advances including image guided navigation and angled endoscopes have shifted paradigm towards minimally invasive surgeries. Open approaches are still relevant for the disease of frontal sinus with lateral extension where effective clearance cannot be obtained if approached endoscopically. Objectives: The objective of this study was to describe the presentation and management of patients of mucormycosis with isolated frontal sinus involvement with help of external approaches. Materials and methods: The available records of the patients were retrieved and analysed. The literature, the associated contributory clinical features and management techniques were reviewed. Results: 4 patients presented with isolated frontal sinus mucor involvement. 3 out of 4 patients had history of diabetes mellitus (75%). All patients had history of covid-19 infection (100%). 3 out of 4 patients had unilateral frontal sinus involvement and were operated by Lynch Howarth approach. Mean age of presentation was 46 years with male predominance. Bicoronal approach was used in one case with bilateral involvement. Conclusion: Although conservative endoscopic surgeries are preferred nowadays for frontal sinus clearance but the extensive bony destruction with lateral extension in our series of patients with isolated frontal sinus mucormycosis warranted the need for open procedures.

Secondary Cutaneous Mucormycosis - Retrospective Analysis From Tertiary Care Hospitall.

Background: Covid-19 infection increases the risk of opportunistic infections like mucormycosis. Cutaneous mucormycosis can occur primarily by direct inoculation or secondary to involvement of the underlying structures. Cutaneous manifestations include tender, erythematous, indurated lesions and necrotic plaques. As the disease evolves, cutaneous features manifest progressively. Objectives: To study the manifestations of the cutaneous signs of sinonasal mucormycosis and management of such cases based on severity of involvement. Materials and methods: A retrospective analysis of 21 patients with diagnosis of cutaneous mucormycosis secondary to sinonasal involvement was done with assessment of their skin lesion, area involved and their clinical stage being noted at the time of admission and after 24 h. Treatment consisted of combination of surgical debridement, daily dressing and liposomal amphotericin B. Observations and Results: Out of total 21 patients, there were 10 males and 11 females. Among risk factors, 14 cases had history of covid 19 infection, 5 had history of steroid intake, 6 had history of ICU stay and all had deranged blood sugar levels. Among disease prognosis, excellent outcomes appeared in stage I and stage III showed worst outcome. Conclusion: Since initial clinical presentation is similar to cellulitis and other soft-tissue infections, early recognition is difficult. In this cohort, the prognosis of secondary cutaneous mucormycosis remained poor, especially in ICU patients and those with numerous predisposing factors. Such patients presented in late stages of the disease and mortality rate was very high in such group.

Self-reported insomnia symptoms, sleep duration, chronotype and the risk of acute myocardial infarction (AMI): a prospective study in the UK Biobank and the HUNT Study.

Insomnia and short/long sleep duration increase the risk of AMI, but their interaction with each other or with chronotype is not well known. We investigated the prospective joint associations of any two of these sleep traits on risk of AMI. We included 302 456 and 31 091 participants without past AMI episodes from UK Biobank (UKBB; 2006-10) and the Trøndelag Health Study (HUNT2; 1995-97), respectively. A total of 6 833 and 2 540 incident AMIs were identified during an average 11.7 and 21.0 years follow-up, in UKBB and HUNT2, respectively. Compared to those who reported normal sleep duration (7-8 h) without insomnia symptoms, the Cox proportional hazard ratios (HRs) for incident AMI in UKBB among participants who reported normal, short and long sleep duration with insomnia symptoms were 1.07 (95% CI 0.99, 1.15), 1.16 (95% CI 1.07, 1.25) and 1.40 (95% CI 1.21, 1.63), respectively. The corresponding HRs in HUNT2 were 1.09 (95% CI 0.95, 1.25), 1.17 (95% CI 0.87, 1.58) and 1.02 (95% CI 0.85, 1.23). The HRs for incident AMI in UKBB among evening chronotypes were 1.19 (95% CI 1.10, 1.29) for those who had insomnia symptoms, 1.18 (95% CI 1.08, 1.29) for those with short sleep duration, and 1.21 (95% CI 1.07, 1.37) for those with long sleep duration, compared to morning chronotypes without another sleep symptom. The relative excess risk for incident AMI in UKBB due to interaction between insomnia symptoms and long sleep duration was 0.25 (95% CI 0.01, 0.48). Insomnia symptoms with long sleep duration may contribute more than just an additive effect of these sleep traits on the risk of AMI.

Normocalcemic Parathyroid Adenoma with Brown's Tumor Maxilla: A Rare Case.

Introduction: Primary hyperparathyroidism due to parathyroid adenoma commonly causes raised serum calcium and focal giant cell lytic lesions in bones known as Brown's tumors. It is more common in females in the post-menopausal age group. Case Report: We report a case of a 29-year-old female patient with Brown's tumor maxilla in a clinical setting of normocalcemic primary hyperparathyroidism. The patient presented to us with facial and palatal swelling for which FNAC was done. Cytology revealed hemosiderin-laden macrophages suspicious for Brown's tumor. On further imaging studies such as CT Neck, Tc99 Sestamibi scan, and other biochemical tests like parathyroid hormone assay and serum calcium level, the diagnosis of a hyperfunctioning parathyroid gland with normal calcium level was made. Parathyroidectomy was performed and parathyroid adenoma came out to be the primary pathology. On post-operative follow up there was regression of the swelling on the face and palate relieving the patient symptomatically. Conclusion: The diagnostic suspicion of primary hyperparathyroidism should be kept in mind whenever a young female presents with suspected Brown's tumor, even with normal serum calcium levels, for appropriate management. Ours was a highly uncommon case that was a diagnostic challenge and had a successful treatment outcome. Very few such cases have been reported in the literature to date to the best of our knowledge.

Comparison of Treatment for Recurrent Respiratory Papillomatosis at a Public County Versus Private Academic Hospital.

OBJECTIVE: To compare patient, disease and treatment characteristics of patients treated for recurrent respiratory papillomatosis (RRP) at a public county versus a private hospital. METHODS: A retrospective cohort study was conducted of adult patients undergoing treatment for RRP at a tertiary-care academic center (TAC, n = 48) versus public safety net hospital (PSNH, n = 14), both staffed by the same Otolaryngology providers. RESULTS: There was no difference between cohorts in age, gender, medical comorbidities, history of juvenile-onset presentation, or history of prior treatment at a different institution. PSNH patients were more likely to be Hispanic/Latino, primarily speak Spanish, have public or no insurance, and reside in a zip code with lower median income compared with TAC patients. Despite living significantly closer to the hospital, PSNH patients were more likely than TAC patients to present with respiratory symptoms (50% versus 20.8%, P = 0.04), and exhibit more than one involved laryngeal subsite at their first surgical intervention (78.6% versus 27.1%, P = 0.001). They also had high rates of referral for otolaryngologic care via the emergency department (42.9%) rather than outpatient specialty referral (35.7%) and were more likely than TAC patients to require urgent intervention (21.4% versus 2.1%, P = 0.03). There was no difference in time interval from first clinic visit to procedure date or total number of treatments. CONCLUSIONS: PSNH patients present with more severe and symptomatic RRP disease compared with TAC patients. This finding may be related to sociodemographic disparities leading to poorer access in care.

Biphenotypic Sinonasal Sarcoma with Intracranial Extension - A Case Report with Review of Literature.

Rationale: Biphenotypic sinonasal sarcoma is a rare malignant tumour exclusively involving the sinonasal cavity. These tumours have variable and atypical presentations. Early approach and correct treatment modalities are key factors in the management of such cases. Patient Concern: A 48-year-old male patient presented with left-sided nasal obstruction and intermittent nasal bleeding for one year. Diagnosis: Biphenotypic sinonasal sarcoma confirmed on histopathological examination and immunohistochemistry. Treatment: The patient underwent surgical excision with left lateral rhinotomy and bifrontal craniotomy with skull base repair. The patient also received postoperative radiotherapy. Outcome: The patient is on regular follow-up with no similar complaints. Take-Away Lesson: Treating team should keep the diagnosis of biphenotypic sinonasal sarcoma in mind while investigating a patient with nasal mass. Surgical management is the treatment of choice, due to its local aggressive nature and proximity to the brain and eyes. Postoperative radiotherapy is vital to prevent tumour recurrence.

Lingual Cysticercosis: A Case Series with Review of Literature.

Cysticercosis is a condition in which humans are infected by the larval form of Pork Tapeworm Taenia solium. Isolated lingual cysticercosis is a rare entity due to the high muscular activity and metabolic rate of tongue which prevents the development of larva. We present a series of three patients with isolated lingual cysticercosis. One patient was treated by medical management while the other two were treated with surgical excision followed by medical therapy. All patients are asymptomatic after repeated follow ups.

Factors Associated With Tolerance for In-Office Laryngeal Laser Procedures.

OBJECTIVES/HYPOTHESIS: A variety of laryngeal pathologies are increasingly being managed with in-office KTP laser (IOKTP) endoscopic procedures. The primary goal of this study was to identify patient characteristics and disease-related features that correlated with tolerance for IOKTP. STUDY DESIGN: Retrospective chart review. METHODS: The study was a retrospective review of adult patients undergoing office-based laryngeal laser procedures between November 2016 and December 2019 at a tertiary care center. Two blinded otolaryngologist reviewers scored videotaped recordings of IOKTP procedures and assessed severity and distribution of disease using a modified Derkay score, and evaluated procedure tolerance using a visual analog scale. RESULTS: A total of 56 patients who received IOKTP procedures for laryngeal pathology were reviewed, 42 male and 14 female, with a mean age of 61 years. Gender, age, and BMI were not correlated with tolerance. There was a moderate, negative correlation between tolerance and total number of pathological anatomic laryngeal subsites (rs(56) = -0.35, P = .01). There was a weak, negative correlation between tolerance and total modified Derkay score (rs(56) = -0.29, P = .03). The median tolerance score was lower for patients with posterior lesions (Mdn = 6.4) compared with patients with non-posterior lesions (Mdn = 7.4), P = .04, and lower for current or former smokers (Mdn = 6.5) compared with never smokers (Mdn = 7.3), P = .04. CONCLUSION: Patients with large disease burden or posterior lesions and patients with smoking history may exhibit poorer tolerance of IOKTP procedures, factors which can help guide pre-procedural counseling and management decisions.

Association of Maternal Plasma Total Cysteine and Growth among Infants in Nepal: A Cohort Study.

Cysteine is a semi-essential amino acid that has been positively associated with growth in children. However, transgenerational effects remain unclear. The aim of this analysis was to assess whether maternal plasma total cysteine (tCys) concentration is associated with various growth indicators in infants living in peri-urban settings in Bhaktapur, Nepal. We used data from the 561 mothers enrolled in an ongoing randomized controlled trial. We built linear regression models to evaluate the associations between maternal tCys and birth weight, length-for-age Z-scores (LAZ) and weight-for-length Z-scores (WLZ) at birth and six months of age. Maternal tCys was inversely associated with birth weight among boys after adjusting for confounders (p < 0.05). In addition, there was a negative association between maternal tCys and LAZ at birth (p < 0.01). No associations between maternal tCys and the other anthropometric indicators were found significant, although there was a tendency for maternal tCys to be associated positively with WLZ at birth among girls (p < 0.10). This is a first study evaluating transgenerational relation of tCys on growth in infants. Further, larger and more comprehensive studies are needed to determine if and how maternal tCys alters child growth.

Schwannoma of the Brachial Plexus: A Rare Case Report.

INTRODUCTION: Brachial plexus schwannomas are extremely rare tumours of the head and neck region accounting for less than 5 % overall. Due to its rarity and anatomic complexity of the brachial plexus, schwannomas in this region present a diagnostic and surgical challenge to the surgeon. CASE REPORT: We present a case of a 56-year-old female who presented with a slow growing right sided neck swelling associated with pain and tingling in the distal end of the right forearm. According to FNAC, imaging studies results, a diagnosis of benign neurogenic tumour possibly schwannoma was made. After taking proper consent patient underwent surgical excision of the tumour. Postoperatively, patient developed numbness and tingling in right arm and stiffness at elbow joint, which is showing improvement after regular physiotherapy sessions. CONCLUSION: Although brachial plexus schwannomas are extremely rare head and neck tumours they should be kept as a differential diagnosis in patients presenting with supraclavicular neck swellings. These are potentially curable lesions. As such, detailed history and examination together with imaging studies is important in establishing a preoperative diagnosis for proper management.

Tuberculous Bronchoesophageal Fistula in Nephrotic Syndrome: A Silent Assassin.

Tuberculosis, a global public health concern, is emerging as an important complication in children with nephrotic syndrome. We report a case of an adolescent with nephrotic syndrome who developed fatal miliary tuberculosis after initiation of steroid therapy, presenting as a bronchoesophageal fistula. The case highlights the importance of maintaining a high index of suspicion prior to starting immunosuppressive therapy in pediatric patients of nephrotic syndrome.

Laryngocele: A Rare Case Report and Review of Literature.

Laryngocele is an abnormal cystic dilatation of the saccule of the larynx. It communicates with the laryngeal lumen and contains air. Laryngocele can be classified as internal (within the larynx), external (outside the larynx) and mixed (both). It is a rare entity. Hereby, we are reporting a case of laryngocele, which presented to us with a diagnostic quandary. After confirming the diagnosis by radiology, patient was operated upon by external approach. In the following article, we also discuss the establishment of the diagnosis and review different surgical modalities for the management of various types of laryngocele.

Annexin II Light Chain p11 Interacts With ENaC to Increase Functional Activity at the Membrane.

The epithelial Na+ channel (ENaC) provides for Na+ absorption in various types of epithelia including the kidney, lung, and colon where ENaC is localized to the apical membrane to enable Na+ entry into the cell. The degree of Na+ entry via ENaC largely depends on the number of active channels localized to the cell membrane, and is tightly controlled by interactions with ubiquitin ligases, kinases, and G-proteins. While regulation of ENaC endocytosis has been well-studied, relatively little is understood of the proteins that govern ENaC exocytosis. We hypothesized that the annexin II light chain, p11, could participate in the transport of ENaC along the exocytic pathway. Our results demonstrate that all three ENaC channel subunits interacted with p11 in an in vitro binding assay. Furthermore, p11 was able to immunoprecipitate ENaC in epithelial cells. Quantitative mass spectrometry of affinity-purified ENaC-p11 complexes recovered several other trafficking proteins including HSP-90 and annexin A6. We also report that p11 exhibits a robust protein expression in cortical collecting duct epithelial cells. However, the expression of p11 in these cells was not influenced by either short-term or long-term exposure to aldosterone. To determine whether the p11 interaction affected ENaC function, we measured amiloride sensitive Na+ currents in Xenopus oocytes or mammalian epithelia co-expressing ENaC and p11 or a siRNA to p11. Results from these experiments showed that p11 significantly augmented ENaC current, whereas knockdown of p11 decreased current. Further, knockdown of p11 reduced ENaC cell surface population suggesting p11 promotes membrane insertion of ENaC. Overall, our findings reveal a novel protein interaction that controls the number of ENaC channels inserted at the membrane via the exocytic pathway.

Complication of an Odontogenic Infection to an Orbital Abscess: The Role of a Medical Fraudster ("Quack").

INTRODUCTION: Complication of an odontogenic infection to an orbital abscess is not a common presentation. The progression from a simple toothache to a condition that may lead to loss of vision is sudden and severe. CASE REPORT: We report a rare case in which a patient developed facial cellulitis that progressed to orbital abscess after unsterile dental manipulation by a medical fraudster ("quack"). The patient was initiated on high-grade antibiotics, which resolved the facial cellulitis. However, the patient developed orbital abscess with restricted mobility of the right eye in the lateral gaze. After radiological confirmation of the abscess, it was drained by an external approach. Due to timely intervention, the extra-ocular mobility was regained, and the vision remained unaffected. CONCLUSION: Knowledge of the routes of the spread of dental infection to the vital structures and the urgent need for aggressive multidisciplinary management is paramount. Furthermore, awareness of the rising quack culture in developing nations needs to be increased.

Type 1 Tympanoplasty by Cartilage Palisade and Temporalis Fascia Technique: A Comparison.

(1) To compare graft take up of type-1 tympanoplasty with cartilage palisade technique with those of type-1 tympanoplasty using autotemporalis fascia. (2) To compare hearing results of type 1 tympanoplasty with cartilage palisade technique with those of type-1 tympanoplasty using autotemporalis fascia. A prospective clinical study. It consisted of 60 patients divided into two groups of 30 patients each. After randomization 30 patients underwent type 1 tympanoplasty using cartilage palisade technique and 30 underwent type 1 tympanoplasty using autotemporalis fascia. In follow up, pure tone audiogram were carried out at 2nd, 4th and 6th month. Clinical assessment was done at 2nd 4th and 6th month. The graft uptake rate between the group 1 and group 2 are 93.33 and 90% respectively. As p value was greater than 0.05 so statistically there is no significant difference between the two group. The post operative air bone gap of the two groups were compared using student t test. The pre op mean of group 1 was 32.5 db and pre op mean of group 2 was 30.66 db. The post op mean of group 1 was 21.33, with standard deviation of 3.6984 and standard error of 0.67523. The post op mean of group 2 was 21.09 with standard deviation of 3.29 and standard error of 0.58261. t value was 0.1357. Analysis was done using student t test and p value was found to be greater than 0.05. p value is greater than 0.05 which shows that there is no statistical difference between the two groups. This study establishes the fact that hearing results after performing type 1 tympanoplasty by autotemporalis fascia when compared with type 1 tympanoplasty performed by cartilage palisade technique showed similar hearing gain and post operatively graft take up rate was also similar in two groups. The disadvantage of reducing the mechanical vibration of the tympanic membrane was overcome by the palisade reconstruction of the tympanic membrane. This study definitely emphasizes upon usage of new grafting materials in reconstruction of tympanic membrane, with similar, if not better functional results, without compromising the acoustic transfer characteristics.

Massive juvenile nasopharyngeal angiofibroma: ode to the open surgical approach.

The management of juvenile nasopharyngeal angiofibroma has undergone a significant evolution, with more surgeons moving towards the minimal invasive endoscopic approaches. Although considered the standard of care by most, an endoscopic approach may not be sufficient for extensive tumours, as exemplified by the current case of a young man presenting with the largest juvenile nasopharyngeal angiofibroma described in English literature until the present that was eventually excised via an anterior external approach.
