MR findings suggestive of idiopathic intracranial hypertension in 117 patients with spontaneous cerebrospinal fluid rhinorrhea.

PURPOSE: The purpose of this study is to document the prevalence of MR findings suggestive of idiopathic intracranial hypertension (IIH) in patients undergoing endoscopic repair of spontaneous CSF rhinorrhea (SCSFR). METHODS: In a retrospective study, MR images of 117 consecutive patients who had undergone endoscopic repair of SCSFR were evaluated for features suggestive of IIH (empty sella, widened optic nerve sheath, tortuous optic nerve, flattened posterior globe, and enlarged Meckel's cave). Pituitary height was used to diagnose partial and complete empty sella. MR images were independently evaluated by two of the authors without knowledge of the clinical findings. Consensus method was used to resolve differences between the two evaluators. RESULTS: Empty or partially empty sella was diagnosed in the MR of 105 (89.7%) patients. In 38/105 (36.2%) patients with empty/partial empty sella, no additional MR findings were present. In 43/105 (41%) patients, one or more of the MR features with high specificity for diagnosis of IIH (flattened posterior globe and enlarged Meckel's cave) were seen. In the other 24 (22.9%) additional MR findings, less specific for IIH (widened optic nerve sheath, tortuous optic nerve) were noted. Papilledema was seen in 11 of 60 (18.3%) patients who underwent funduscopic examination. All patients with papilledema had empty/partial empty sella, and 9/11 (81.8%) had an additional MR finding suggestive of IIH. CONCLUSION: The majority of patients with SCSFR have MR imaging features of IIH. These imaging features should be a major component of previously published modified diagnostic criteria for IIH in patients with SCSFR.

Changes in olfaction & quality of life following standard medical therapy in patients with intermittent & persistent allergic rhinitis.

Background & objectives: Allergic rhinitis (AR) is an inflammatory disease prevalent worldwide which can affect both olfaction and quality of life (QoL). The objective of the present study was to assess olfaction and QoL changes in patients with AR before and after medical therapy. Methods: Adult participants (>18 yr) with AR were recruited for this study. These patients prospectively underwent olfaction testing using the modified Connecticut Chemosensory Clinical Research Centre Test and QoL assessment using Rhinoconjunctivitis QoL Questionnaire (RQLQ) before and after standard medical therapy with topical steroids and/antihistaminics. Results: Of the 150 patients recruited, 72 per cent had intermittent AR. The symptom of hyposmia was present in 34 patients (22.7%) and was more prevalent in patients with moderate-to-severe type of AR (P<0.001). However, olfaction testing revealed hyposmia/anosmia in 44 patients (29.3%). Mean composite olfaction scores were significantly higher in patients with mild AR compared to moderate/severe AR (P=0.026). The pre-therapy mean composite olfaction score in the 34 patients with olfaction disturbances was 3.1 standard deviation (±1.06 SD). Following therapy, the mean composite olfaction score rose to 4.3 (±1.34 SD) and this change was found to be significant (P<0.001). Mean pre-therapy RQLQ scores were 2.87 (0.06-5.33) overall. Significant improvement was also found in RQLQ scores following therapy (P<0.001). Mean RQLQ scores were significantly lower in those with moderate-to-severe AR (P<0.001) as well as those with intermittent AR (P=0.004). Nine patients had persistently high RQLQ scores after medical therapy. Interpretation & conclusions: Both olfaction and QoL showed significant improvement after medical therapy in Indian adults with AR. In those patients who do not improve, other causes must be sought for the persistent symptoms.

Rhino-orbito-cerebral mucormycosis: patient characteristics in pre-COVID-19 and COVID-19 period.

BACKGROUND: Rhino-orbito-cerebral-mucormycosis (ROCM), a rare and potentially fatal disease was seen in increasing numbers during the COVID-19 pandemic. This study describes and compares the patient characteristics and outcomes in COVID-19 associated mucormycosis (CAM) and non-COVID-19 mucormycosis (non-CAM). METHODOLOGY: CAM patients (24 cases) were recruited from the COVID-19 period and non-CAM (24 controls) from the pre-COVID-19 period. Clinical data of the CAM group was collected retrospectively with 3 month outcomes prospectively. The non-CAM group data was collected retrospectively. Patient characteristics were compared and risk factors for mortality in ROCM were assessed. RESULTS: Orbital symptoms [altered vision, restricted eye movements, ptosis] and intracranial involvement were higher in CAM patients on presentation. Similarly, the radiological involvement of orbit (orbital apex, superior orbital fissure) and intracranial cavity (intracranial thrombosis, cavernous sinus) was also higher in CAM patients. Newly detected diabetes was found only in CAM patients (29.2%). Although univariate analysis suggested an increased mortality risk in ROCM patients with orbital involvement, the multivariate analysis showed no increased risk with any of the parameters assessed, including COVID-19 positivity. CONCLUSIONS: Compared to the non-CAM, the disease presentation was severe in CAM with higher frequency of orbital and intracranial involvement. However, with early detection and treatment, the short term survival was comparable in both groups.

Rhinofacial conidiobolomycosis: Clinical and microbiological characterisation and shift in the management of a rare disease.

BACKGROUND: Conidiobolomycosis is a rare tropical rhinofacial fungal infection which has not been well characterised. The available evidence in its management is sparse due to lack of clinical studies and the limited data on antifungal susceptibility patterns. OBJECTIVE: To analyse the clinical manifestations, antifungal treatment and outcomes of patients with conidiobolomycosis and to determine antifungal susceptibility profiles of the isolates. PATIENTS/METHODS: Retrospective analysis of data of all patients with a diagnosis of conidiobolomycosis confirmed by histopathology and culture at a tertiary care hospital from 2012 to 2019 was done. RESULTS: There were 22 patients, 21 males and one female, with a mean age of 37.1 years. Most common presenting symptom was nasal obstruction, found in 20 (90.90%) patients. Patients who presented within 12 months had a better cure rate (85%) compared to those who presented late (67%). Among the 19 patients who had a follow-up, good outcome was seen in 15 of the 17 (88.24%) patients who were on itraconazole or potassium iodide containing regimen. Of the six patients who received additional trimethoprim-sulphamethoxazole (co-trimoxazole), 67% showed good outcome with two patients showing complete cure and two patients still on treatment with significant improvement. High minimum inhibitory concentration (MIC) values were noted for azoles and amphotericin B, whereas co-trimoxazole showed lowest MIC ranges. CONCLUSION: Itraconazole and potassium iodide are reasonable first-line options for the treatment of conidiobolomycosis. Good clinical response to KI and comparatively lower MIC of co-trimoxazole are promising. Further studies are required for developing clinical breakpoints that can predict therapeutic outcomes.

Association of Streptococcus pneumoniae nasopharyngeal colonization and other risk factors with acute otitis media in an unvaccinated Indian birth cohort.

In order to study the epidemiology of acute otitis media (AOM) and Streptococcus pneumoniae nasopharyngeal colonization in the first 2 years of life, we followed up an unvaccinated birth cohort monthly and at visits when sick, with otoscopy to detect AOM and performed nasopharyngeal swabbing to detect S. pneumoniae. Serotyping of positive cultures was also performed. Of 210 babies who were enrolled at birth, 61 (29·05%) experienced 128 episodes of AOM [relative risk 2·63, 95% confidence interval (CI) 1·21-5·75] with maximum incidence in the second half of the first year of life. Episodes ranged from 1 to 7 (mean 2·1 episodes). Most (86·9%) babies with AOM had a positive culture swab giving an odds ratio (OR) of 1·93 (95% CI 1·03-3·62, P = 0·041) for this association. Other risk factors identified for AOM were winter season (OR 3·46, 95% CI 1·56-7·30, P = 0·001), upper respiratory infection (OR 2·43, 95% CI 1·43-4·51, P = 0·005); residents of small households were less likely to develop AOM (OR 0·32, 95% CI 0·17-0·57, P < 0·01). Common S. pneumoniae serotypes isolated during episodes were 19, 6, 15, 35, 7, 23, 9 and 10 which indicated a theoretical coverage for pneumococcal vaccines PCV10 and PCV13 constituent serotypes of 62·8%. We conclude that AOM in Indian infants is often associated with S. pneumoniae colonization of the nasopharynx as well as other risk factors.

Association between vascular supply, stage and tumour size of juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular tumour seen in adolescent males. To study the vascular pattern of these tumours, we retrospectively reviewed the records of patients with JNA who underwent preoperative angiography. Most (82.2 %) of the 45 patients assessed were Radkowski stage III with a mean size of 5.29 cm. There was a significant association between tumour stage and size (p = 0.029). Ten different vessels were seen to supply these tumours. All tumours had primary supply from the distal third of the ipsilateral internal maxillary artery (IMA). Accessory vessel supply was chiefly from the Vidian branch of internal carotid artery (ICA) (55.6 %). Stage III tumours were supplied by a greater number of feeding vessels than earlier stage tumours (p < 0.01). Larger tumours were more likely to have ICA supply (p = 0.04). Bilateral supply was seen in 48.7 %. However, there was no predominance of bilateral over ipsilateral IMA supply even in advanced stage tumours. One patient in our series was found to have a caroticocavernous fistula. Residual or recurrent tumours were characterized by new vasculature (100 %) and greater accessory supply from the ipsilateral ICA (85.7 %). Our study highlights the fact that surgical planning cannot be dependent on staging alone and should include preoperative assessment of tumour vasculature by angiography.

Current therapeutic protocols for chronic granulomatous fungal sinusitis.

BACKGROUND: The treatment of chronic granulomatous fungal sinusitis (CGFS), a rare form of invasive fungal sinusitis, is controversial. AIM: To assess the response to postoperative antifungal therapy in patients with CGFS and suggest an effective treatment protocol. METHODOLOGY: Clinical records of patients with CGFS who had undergone excisive surgery followed by antifungal therapy were reviewed to assess current disease status. RESULTS: Fourteen male and 4 female patients were diagnosed with CGFS, based on typical histopathological and fungal smear/ culture results. Aspergillus flavus was isolated from 88.9% cases. Stage 1 patients had resectable sinonasal disease, stage 2 had additional spread to orbit/palate and stage 3 had extensive disease. Follow-up ranged from 6 months to 8 years. Residual disease was seen in all but one patient who received amphotericin B as first line therapy and in none of those who received itraconazole or voriconazole. Even those who received azoles as second line therapy were disease free at last follow-up. CONCLUSION: Surgery followed by itraconazole or voriconazole for Stage 1 and 2 disease and voriconazole for stage 3 disease is recommended for a good outcome. Amphotericin B is not recommended as first line therapy for CGFS.

Different types of fungal sinusitis occurring concurrently: implications for therapy.

The purpose of this study is to describe the clinical and histopathological features, management and outcome of a series of patients with simultaneous occurrence of invasive and non-invasive fungal sinusitis (mixed fungal sinusitis). The histopathological records of patients with fungal sinusitis seen over the last 6 years were reviewed. The clinical, histopathological, treatment and follow up details of all cases with mixed fungal sinusitis were noted. Six cases of mixed fungal sinusitis with concurrent occurrence of chronic granulomatous fungal sinusitis and allergic fungal sinusitis (AFS) were seen during the study period. Most (83.3 %) had bilateral disease. All patients had undergone prior endoscopic sinus surgery at least once within the previous 2 years. Histopathological features showed predominance of invasive disease in half the patients. Except for one patient who did not report for follow up, all patients with predominant chronic granulomatous fungal sinusitis received systemic antifungal therapy and inhaled steroids. Those with predominant features of AFS received oral and inhaled steroids. Five patients with mixed fungal sinusitis who had follow up ranging from 6 months to 5 years were disease free following treatment. Mixed fungal sinusitis should be recognized by the surgeon and pathologist as a separate category of fungal sinusitis whose treatment depends on accurate histological diagnosis. A good outcome may be expected with appropriate therapy.

Effect of the nasal airflow inducing manoeuvre on olfaction and quality of life after laryngectomy.

OBJECTIVE: To assess the effectiveness of the nasal airflow inducing manoeuvre or 'polite yawn' technique in improving olfaction and quality of life in laryngectomised patients. METHODS: Using a prospective study design, 42 patients scheduled to undergo laryngectomy at a tertiary care centre were subjected to olfaction testing before surgery and two weeks following the surgery. The nasal airflow inducing manoeuvre was taught, and the olfaction test was repeated with the patient performing the nasal airflow inducing manoeuvre. Quality of life was assessed using the Appetite, Hunger and Sensory Perception questionnaire with calculation of scores after the patient had learnt the nasal airflow inducing manoeuvre. RESULTS: There was a significant reduction in the composite olfaction score, from a mean (standard deviation) baseline value of 4.01 (1.39) to 0.44 (0.51), two weeks after surgery (p < 0.001). After practising the nasal airflow inducing manoeuvre, the olfaction scores increased to 3.05 (1.32) (p < 0.001). Appetite, Hunger and Sensory Perception questionnaire scores ranged from 52 to 110 (normal range, 29-145), suggesting an improvement in the quality of life of patients. CONCLUSION: The nasal airflow inducing manoeuvre, an inexpensive, simple, patient-friendly manoeuvre, can be used in the olfaction rehabilitation of patients undergoing laryngectomy.

Unusual Cause of Neonatal Stertor.

We report a case of neonatal respiratory distress caused by an epignathus. This rare tumour, arising from the basisphenoid and protruding from the mouth, is associated with high perinatal mortality. We highlight unique clinico-radiological findings and multidisciplinary approach for a successful outcome. We review oropharyngeal teratomas reported in the literature with current management approaches.

Risk factors and predictors of mortality in acute invasive fungal sinusitis - a single-institution experience.

OBJECTIVE: To determine risk factors affecting mortality in acute invasive fungal sinusitis. METHOD: This observational cohort study was conducted over a five-year period. RESULTS: Of 109 recruited patients, 90 (82.6 per cent) had diabetes mellitus. Predominant fungi were zygomycetes (72.6 per cent) with Rhizopus arrhizus being most common. Of the patients, 12.8 per cent showed a positive biopsy report from radiologically normal sinuses. Factors affecting mortality on multivariate analysis were: female sex (p = 0.022), less than two weeks between symptoms and first intervention (p = 0.01), and intracranial involvement (p = 0.034). Other factors significant on univariate analysis were: peri-orbital swelling (p = 0.016), restricted ocular movements (p = 0.053), intracranial symptoms (p = 0.008), posterior disease (p = 0.058), imaging showing ocular involvement (p = 0.041), fungus being zygomycetes (p = 0.050) and post-operative cavity infection (p = 0.032). Bilateral, palatal and retromaxillary involvement were not associated with poor prognosis. CONCLUSION: Diagnosis of acute invasive fungal sinusitis requires a high index of clinical suspicion. Recognition of factors associated with poor prognosis can help when counselling patients, and can help initiate urgent intervention by debridement and antifungal therapy. Post-operative nasal and sinus cavity care is important to reduce mortality.

Effect of Silver Nitrate Cauterisation of Nasal Mucosa on Quality-of-Life and Histology in Patients with Intractable Chronic Rhinitis.

Patients with chronic rhinitis causing intractable sneezing which is non-responsive to conventional medication require alternative therapies. The aim of the study was to ascertain the effect of topical 10% silver nitrate solution on the inferior turbinate mucosa as well as quality of life in such patients. Patients with severe chronic rhinitis who failed conventional therapy had application of 10% silver nitrate solution to inferior turbinate mucosa. The number of sneezes/day and mini Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) score was noted before and 8 to 16 weeks after treatment. Pre- and post treatment turbinate biopsies were performed to assess histological changes. At baseline, 67 patients had a mean of 36.6 sneezes/day and mean mini RQLQ score of 4.0 ± 0.7. Pre-treatment biopsies showed epithelial denudation and hyalinization of basement membrane. Following 10% silver nitrate application, 64/67 (95.5%) patients showed significant reduction in number of sneezes both at 1 week (p < 0.001) and 8-16 weeks (mean = 5.5 ± 7.8; p < 0.001). Post- treatment mean global mini RQLQ score was also significantly reduced (mean = 1.3 ± 1.1; p < 0.001). A single application was sufficient in 70.1% patients. There were no complications. Squamous metaplasia (p = 0.005) and epithelial hyperplasia (p = 0.013) as well as epithelial and basement membrane restoration occurred following therapy. 10% silver nitrate solution application is an effective and safe office- based procedure which significantly reduces sneezing improves QoL with corresponding histological changes.

Characteristics of Chronic Rhinosinusitis with Nasal Polyps Based on Allergic Mucin and Fungal Elements in Patients Undergoing Revision Endoscopic Sinus Surgery.

This study sought to document the features in chronic rhinosinusitis with nasal polyp (CRSwNP) patients undergoing revision endoscopic sinus surgery (RESS), based on presence or absence of allergic mucin (AM) and fungal elements (F). A retrospective chart review of RESS cases collected Lund Mackay score (LMS), endoscopic, microbiological, histopathological, surgical and follow-up data of these patients. Patients were categorised into AM + F +, AM + F-, AM-F + and AM-F- subgroups based on the presence or absence of AM and F. The total serum IgE was significantly higher (p > 0.001) in the AM + F + subgroup. Other factors analysed including LMS, duration from previous surgery, comorbidities, degree of inflammation and disease recurrence showed no specific predilection among subgroups. Patients with a retained middle turbinate showed lesser (p = 0.04) recurrence on follow-up. Subgroups of recurrent CRSwNP showed similar characteristics and had further disease recurrence which was independent of allergic mucin and fungal elements. The presence of an intact healthy middle turbinate could reduce early disease recurrence following RESS.

Revised workflow practices in the management of acute invasive fungal sinusitis during the coronavirus disease 2019 pandemic.

OBJECTIVE: To document changes in evaluation protocols for acute invasive fungal sinusitis during the coronavirus disease 2019 pandemic, and to analyse concordance between clinical and histopathological diagnoses based on new practice guidelines. METHODS: Protocols for the evaluation of patients with suspected acute invasive fungal sinusitis both prior and during the coronavirus disease 2019 period are described. A retrospective analysis of patients presenting with suspected acute invasive fungal sinusitis from 1 May to 30 June 2021 was conducted, with assessment of the concordance between clinical and final diagnoses. RESULTS: Among 171 patients with high clinical suspicion, 160 (93.6 per cent) had a final histopathological diagnosis of invasive fungal sinusitis, concordant with the clinical diagnosis, with sensitivity of 100 per cent, positive predictive value of 93.6 per cent and negative predictive value of 100 per cent. CONCLUSION: The study highlights a valuable screening tool with good accuracy, involving emphasis on 'red flag' signs in high-risk populations. This could be valuable in situations demanding the avoidance of aerosol-generating procedures and in resource-limited settings facilitating early referral to higher level care centres.

Unusual complications of bone wax at the skull base.

OBJECTIVE: This study aimed to describe the clinical presentation, microbiological profile and management of complications of bone wax usage for surgical procedures at the skull base. METHOD: The case records of a series of five patients who developed post-operative surgical site complications because of bone wax usage during skull base surgery were reviewed. RESULTS: In all five patients, persistent site-specific clinical features were noted along with intra-operative presence of excessive bone wax. Three unique cases of presentation, one with a fungal brain abscess because of Aspergillus flavus infection, another with fungal osteomyelitis because of Trichosporon beigelii infection and a third with intradural migration of bone wax into the cerebellopontine angle cistern are highlighted. CONCLUSION: The presentation of surgical site infection at the skull base because of excessive use of bone wax can be manifold. The need for testing appropriate cultures including fungal culture is highlighted.

Changes in pattern of presentation of patients with unilateral vestibular schwannoma over two decades: Influence of cell phone use in early diagnosis.

We aimed to study whether the increased use of cell phone in south Asia over the past two decades has impacted presentation of patients with vestibular schwannoma (VS). In this observational cohort study, data on cell phone use and severity of hearing loss and tumor size was collected using a questionnaire through a patient interview (n = 62) in consecutive patients with VS managed between 2017 and 2020. Association between cell phone use and severity of hearing loss and tumor size were studied and compared with our data published earlier when telephone use was not widely prevalent. 71% of the 62 patients (aged between 15 and 81 years) had large or giant VS. Pure tone audiometry showed moderately severe or profound hearing loss in77.4%. Sixty (96.7%) patients used cell phones. 50% of patients complained of difficulty in using their cell phone because of hearing loss. Compared to the earlier era, a higher proportion consulted an ENT surgeon first for hearing loss (59.7% vs 26%; p = 0.0005) and had small or medium sized tumors (29% vs 8%; p = 0.008) with a smaller mean tumor size (3.3 vs 3.9 cm; p = 0.03). Increased cell phone use has led to earlier diagnosis of VS and smaller tumours in recent years when compared to an earlier era. However, the vast majority of patients continue to present with severe to profound hearing loss and large tumors.

A prospective, randomised, placebo-controlled trial of postoperative oral steroid in allergic fungal sinusitis.

The aim of this study is to determine the effectiveness of postoperative oral steroid in controlling disease in patients with allergic fungal sinusitis (AFS). The study design includes prospective, randomised, double blind,placebo-controlled trial using oral prednisolone.Twenty-four patients diagnosed with AFS underwent sinus surgery (endoscopic sinus surgery with or without open surgery) to completely excise disease. Patients were randomised to receive either oral steroid (n = 12) or placebo(n = 12) soon after surgery. All patients were also administered itraconazole and steroid nasal spray in the postoperative period. Subjective evaluation of symptom relief and objective evaluation by rigid nasal endoscopy at 6 and 12 weeks following surgery was performed. After12 weeks, the code was broken and the two groups of patients were identified to note their response to treatment.At 6 weeks, complete relief of preoperative symptoms was obtained in eight patients who had received oral steroid and none who had received placebo (p = 0.001). Partial relief of preoperative symptoms was obtained in four who had received oral steroid and eight who had received placebo.Nasal endoscopy revealed that 8 of 12 patients who had received oral steroid and 1 patient who had received placebo were disease free (p = 0.009). At 12 weeks, complete symptom relief was obtained by all patients who received oral steroid but only one who received placebo(p = 0.0001). Nasal endoscopy at 12 weeks revealed that all 12 patients who had received oral steroid and only 1 patient (the same patient) who had received placebo were disease free (p = 0.0001). In conclusion, postoperative oral steroid in a tapering dose produces significant subjective and objective improvement of patients with AFS. It is also effective in preventing early recurrence. Inclusion of post operative oral steroid therapy for at least 12 weeks is recommended in all patients who undergo excisive surgery for AFS.

Sinonasal organising haematoma - a little known entity.

INTRODUCTION: Sinonasal organising haematoma is a recently described, rare, benign inflammatory condition, which closely resembles malignancy in its clinical presentation. OBJECTIVE: To describe the clinical features of organising haematoma and to review the evolution of surgical options successfully used. METHODS: A retrospective review of charts of all patients with a histopathological diagnosis of sinonasal organising haematoma was performed. RESULTS: Six (60%) of the 10 patients were male with a mean age of 47.4 years. All patients had unilateral disease with recurrent epistaxis as the presenting symptom. Maxillary sinus was the most commonly involved sinus. There was no history of trauma in any of the patients. Hypertension (80%) was the most commonly associated comorbidity. Contrast-enhanced CT scan of the paranasal sinuses showed heterogeneous sinus opacification with/without bone erosion. Histopathological examination was diagnostic. Complete endoscopic excision was done in all patients resulting in resolution of the disease. CONCLUSION: Awareness of this relatively new clinical entity and its evaluation and treatment is important for otolaryngologists, maxillofacial surgeons and pathologists alike. Despite the clinical picture of malignancy, histopathological features of benign disease can safely dispel such a diagnosis.

Deep head and neck infections: outcome following empirical therapy with early generation antibiotics.

In order to study the bacteriological profile, antibiotic sensitivity and outcome following empirical therapy with early generation antibiotics in patients with deep head and neck infection, a retrospective review of 42 patients admitted for drainage and intravenous antibiotic therapy was performed. Ludwig's angina was the commonest infection, with the most common organisms isolated being Group F ß-haemolytic (15%) and non-haemolytic (12.5%) streptococcus. All streptococci and anaerobic gram-positive cocci were susceptible to penicillin. S. aureus isolates were oxacillin-sensitive and enterococcus isolates were ampicillin-sensitive. All 42 patients received empirical therapy with either intravenous penicillin or its derivatives. In only three patients was a change of antibiotic required based on culture and sensitivity results. Early generation antibiotics appear ideal as empirical therapy for deep head and neck infection.
