Which is Better in Predicting CT Scores in Patients with Chronic Rhinosinusitis after Medical treatment-Baseline Rhinosinusitis Disability Index (RSDI) or Endoscopic Score?

Introduction

Rhinosinusitis disability index (RSDI) questionnaire is used to assess the severity of chronic rhinosinusitis (CRS) from the patient's perspective. The severity of CRS can be measured objectively with the endoscope and computed tomogram (CT) using the Lund-Kennedy endoscopic score and Mackay-Lund scores respectively. The objective of the study is to evaluate whether baseline RSDI and Lund-Kennedy (LK) endoscopy scoring can help predict the Mackay-Lund CT (MKLCT) scores after medical treatment in patients with CRS.

Methodology

This is a prospective, observational study, carried out from 1st October 2017 to 30th September 2019 in the ENT out- patient department at a tertiary hospital in Northern India. 90 patients diagnosed with CRS were enrolled consecutively in the study. RSDI questionnaire was filled out for all the participants. They all underwent a diagnostic endoscopy and CRS was graded according to the Lund-Kennedy endoscopic scores. All participants were given medical treatment. Patients underwent CT of the paranasal sinuses after medical treatment and the MLKCT scores were calculated. The baseline RSDI and Lund-Kennedy scores were correlated with the MKLCT scores using Spearman's Rank correlation tests. The diagnostic ability of the RSDI and LK endoscopy scores to predict the least MKLCT scores was compared using the receiver operator characteristics curves (ROC).

Results

A statistically significant correlation was seen with LK endoscopy scores and MKLCT scores (r = 0.396, p < 0.001) Among the individual parameters of the LK endoscopy scores only the polyp score had a statistically significant correlation with MKLCT scores (r = 0.593, p < 0.001). A weak negative correlation (r = - 0.058, p = 0.586) was seen between the RSDI scores and MKLCT scores. AUC in ROC curves for a LK endoscopy scores and RSDI scores were 0.690 and 0.462 respectively. Cut-off for predicting a MKLCT score of one or more for RSDI score was 25, with a sensitivity of 61% and specificity of 38.5%. Similarly, the cut-off for LK endoscopic score was 4.5, with a sensitivity of 68.8% and specificity of 61.5%.

Conclusion

Statistically significant (p < 0.001) association was found between baseline Lund-Kennedy endoscopic scores and Mackay-Lund CT scores post medical treatment. No significant association was found between RSDI scores and Mackay-Lund CT scores. ROC analysis indicated that Lund- Kennedy endoscopy score is a more accurate tool than RSDI score to predict a Mackay-Lund CT scores after medical treatment.

The different clinical presentations of pediatric allergic fungal sinusitis

In this paper, we aim to study the different clinical presentations of pediatric allergic fungal sinusitis (AFS) in the Eastern Province of Saudi Arabia, and to review the experience in the diagnosis & management of AFS in children at King Fahad Specialist Hospital. This study is a retrospective case series of pediatric patients diagnosed and managed as AFS at a tertiary referral hospital in Saudi Arabia. The clinical presentation of pediatric AFS varies widely and includes unilateral, unilateral with proptosis, bilateral, alternating, isolated sphenoid and extensive with intracranial & intraorbital involvements. Children with AFS present with different clinical features when compared to adults. Therefore, they require a high index of suspicion for evaluation and early aggressive treatment.

Pediatric Allergic Fungal Rhinosinusitis: Does Age Make a Difference?

Background Allergic fungal rhinosinusitis (AFRS) is a hypersensitive response to fungi within the sinus cavity. Children represent a challenging group of patients with sinonasal disorders, as their sinus anatomy is not fully developed. This study aimed to determine the various clinical manifestations and management outcomes in children with AFRS. Methods A retrospective chart review of children who underwent sinus surgery for AFRS at a tertiary healthcare center between 2005 and 2021 was performed. Demographics, clinical manifestations, radiological and laboratory results, treatment regimens, complications, and recurrence rates were collected. Subanalysis was performed based on age at first surgery: group A (<13 years) and group B (≥13 years). Results Overall, 35 children underwent sinus surgery for AFRS during the study period. The mean patient age at the time of surgery was 14 years. Bilaterality was present in 15/35 (42.9%) patients and anosmia in 12/35 (34.3%). Polyps on examination were present in 31/35 (88.6%) patients and proptosis in 8/35 (22.9%). Sub-analysis revealed that group A showed less bilateral disease (11.4%) than group B (31.4%) and a lower Lund-Mackay score (median=11.50 and 17, respectively, p=0.002). Conclusion Age at surgery did not have an impact on the outcome. A high index of suspicion should be exercised when dealing with children with sinonasal symptoms that do not respond to routine treatment and should be investigated for chronic sinusitis.

Literature review. Noninvasive fungal rhinosinusitis

Fungus ball (FB) of the paranasal sinuses has a distinctive clinicopathological presentation. The disease occurs more frequently in elderly patients and has a female preponderance. Classically, it involves only one paranasal sinus in more than 90% of the cases, most commonly the maxillary sinus. Imaging characteristics (calcifications and / or erosion of the inner wall of the sinus visible on CT) and histopathological ones (luminal aggregation of fungal hyphae) confirm the diagnosis.

Allergic fungal rhinosinusitis (AFRS) usually occurs in younger, immunocompetent patients, with a history of atopy, including allergic rhinitis and / or asthma, or a long clinical picture of chronic rhinosinusitis (CRS), refractory to antibiotic treatment. Nasal polyps (NP) are present in almost all patients, while extra-sinusal complications are described only in some of them. Usually, there is involvement of several sinuses, as well as bilateral damage. The definitive diagnosis is confirmed only by examining surgical specimens - the characteristic appearance of eosinophilic mucin is the most reliable indicator of AFRS.
