Prevelance of Common Aeroallergens in Allergic Rhinitis and its Correlation with Bronchial Asthma: A Study on 798 Patients by Skin Prick Test.

Allergic rhinitis affects 30% of the Indian population (Dey et al. in Int Arch Allergy Immunol 178:60-65, 2019). Patients can be sensitive to single or multiple allergens. Polysensitization is more common (Bousquet et al. in Ann Epidemiol 20:797-803, 2010; Arbes et al. in J Allergy Clin Immunol 116:377-383, 2005). Sensitization to multiple allergens may have a role in the severity and the association of Asthma in such patients. A total of 798 patients with allergic rhinitis (SFAR ≥ 7) were included. Disease severity and associated symptoms were evaluated using questionnaire. Each patient underwent a Skin prick test with an allergen panel of 35 allergens each (Annesi-Maesano et al. in Allergy 57:107-114, 2002) and the results were evaluated to study the association of asthma and severity of Allergic rhinitis. Data consisting of 389 (48.7%) males and 409 (51.3%) females were assessed. A total of 82.2% of the study population of symptomatic patients were sensitized to at least one of the allergens. Seventy patients (8.78%) had associated asthma. Forty-four patients were polysensitized and fifteen were mono sensitized. Among polysensitized patients, 36 patients had sensitization to at least 6 different allergens. Dermatophagoides pteronyssinus was the most common allergen among asthma patients. This study provides a thorough knowledge of locally prevalent aeroallergens which is essential for the prompt diagnosis and treatment of allergic patients. Skin prick test can be a non-invasive vital tool in analyzing patterns of allergen exposure, the prevalence of allergen, sensitizing potential of different allergens in that specific geographic area.

Sinonasal and Olfactory Quality of Life in Endoscopic Pituitary Surgery and Time Interval to Olfactory Recovery: A Comparative Prospective Study.

Background and Objective: Superior turbinate manipulation is often required in cases of narrow cavities and expanded endonasal approaches with concern for olfaction. The objective of the study was to compare the pre- and postoperative olfactory function in patients undergoing endoscopic endonasal transsphenoidal pituitary excision with and without superior turbinectomy, using the Pocket Smell Identification Test and the quality of life (QOL) and Sinonasal Outcome Test-22 (SNOT-22) scores, irrespective of the extension (Knosp grading) of pituitary tumors. We also aimed to identify olfactory neurons in the excised superior turbinate with immunohistochemical (IHC) stains and correlate them with clinical findings. Materials and Methods: The study was a prospective, randomized study performed in a tertiary center. Two groups A and B, with superior turbinate preserved and resected, respectively, during endoscopic pituitary resection, were compared using pre- and postoperative Pocket Smell Identification Test and QOL and SNOT-22 scores. The superior turbinate was subjected to IHC staining to identify the presence of olfactory neurons in patients with tumors of pituitary gland requiring endoscopic trans-sphenoid resection. Results: Fifty patients with sellar tumors were enrolled. The mean age of patients in this study was 46.15 years. The minimum age was 18 years and the maximum was 75 years. Of the 50 patients in the study, 18 were female and 32 were male. Eleven patients had more than one presenting complaint. Loss of vision was the commonest and altered sensorium was the rarest symptom. Conclusion: Superior turbinectomy is a viable option to gain wider access to sella without affecting the sinonasal function, quality of life, and olfaction. There was doubtful presence of olfactory neurons in superior turbinate. The extent of tumor resection and postoperative complications were unaffected and statistically nonsignificant in both the groups.

Primary Calvarial Ewing Sarcoma: A Case Series.

Background Calvarial Ewing tumor is a relatively rare differential among bony neoplasms. We present our experience of managing primary calvarial Ewing sarcoma (EWS), highlighting their clinical and radiological findings. Method In a retrospective analysis, we evaluated our 12-year database for pathologically proven EWS. A literature search was conducted for the comparative presentation and update on the management and outcome. Result From January 2008 to December 2020, we managed eight patients (male:female = 5:3; age range 6 months to 19 years, mean 11.5 years) harboring primary calvarial EWS. All cases underwent wide local excision; two patients required intradural tumor resection, while one required rotation flap for scalp reconstruction. Mean hospital stay was 8 days. All patients received adjuvant chemo- and radiotherapy. Three patients remained asymptomatic at 5 years of follow-up, while two patients died. Conclusion Primary calvarial EWS is a rare entity. It usually affects patients in the first two decades of life. These tumors can be purely intracranial, causing raised intracranial pressure symptoms, which may exhibit rapidly enlarging subgaleal tumors with only cosmetic deformities or symptoms of both. Radical excision followed by adjuvant therapy may offer a favorable long-term outcome.

Management of CVJ tuberculosis: the changing paradigm.

BACKGROUND: The literature seems fractured for the management of craniovertebral junction (CVJ)-tuberculosis (TB). Presently, non-surgical management has been in vogue for neurologically intact patients. On the contrary, severely disabled cases of CVJ-TB continue to attract discussion, tilted towards surgical intervention. We present our experience with the non-surgical management of CVJ-TB tailored to their neurological status. METHODS: Authors managed 37 cases (2004-2019; age 1-57 years, mean 36 years) of CVJ-TB, of which eighteen (18/37, 48.6%) were severely disabled (Nurick grade ≥ 3) with a mean follow-up of 84 months (48-192 months). Irrespective of the clinical status and radiological findings, all patients were managed on medical management only. Needle aspiration established pathology in 23 (62.2%) cases, while 9 (24.3%) cases required drainage of an abscess. All patients received 18 months of anti-tubercular therapy (ATT). In patients with Nurick grade ≥ 3 and documented AAD, we applied halo vest for 12 months to achieve cervical immobilization. Only hard cervical collar for 3 months was prescribed in patients with no documented AAD. RESULTS: All minimally disabled cases (Nurick grade ≤ 2, n = 19) responded favorably (n = 18) to ATT, except for an infant, who succumbed to irreversible hypoxic brain damage due to the obstructed aero-digestive gateway. Of the severely disabled cases (Nurick grade ≥ 3, n = 18), 16 cases had favorable outcomes with only external orthosis (12) and 18-month ATT. One patient succumbed to multiple cerebral infarcts, while one required realignment surgery at CVJ due to fusion in malaligned position. CONCLUSION: The authors conclude that the disability grading of CVJ-TB is pertinent only for assessing the functional disability of patients at presentation, with minimal relevance in deciding its management strategy. Irrespective of neurological disability, almost all patients respond favorably to external immobilization and ATT.

Endoscopic management of congenital nasal meningoencephaloceles: a short series of 15 paediatric cases.

PURPOSE: To retrospectively analyse surgical management of clinico-radiologically proven nasal meningoencephalocele amongst children and results of repair with single-layer septo-mucosal flap at a tertiary skull base surgery centre in north India. METHODS: Fifteen children with clinic-radiological nasal meningoencephaloceles with or without CSF rhinorrhoea were included. Radiological scans included CT scans and MRI scans for all cases to delineate soft tissue and bony architecture. All children underwent endoscopic excision of encephaloceles and repair of the skull base defect. RESULTS: The authors were successful in fourteen cases. Successful cases included 4 children less than 6 months of age who underwent single-layer rotated septo-mucosal flaps, thereby avoiding donor site morbidity. CONCLUSION: As endoscopic excision of nasal encephalocele is an established management approach, the authors take the concept of minimally invasive surgery a step further by successfully managing these lesions with single-layer repair. Vascularized septo-mucosal flap seems to be the only determining factor for a successful repair for congenital meningoencephalocele. However, a prospective study comprising a larger subset of patients would substantiate the assumption.
