Baseline findings of a multicentric ambispective cohort study (2021-2022) among hospitalised mucormycosis patients in India.

In India, the incidence of mucormycosis reached high levels during 2021-2022, coinciding with the COVID-19 pandemic. In response to this, we established a multicentric ambispective cohort of patients hospitalised with mucormycosis across India. In this paper, we report their baseline profile, clinical characteristics and outcomes at discharge. Patients hospitalized for mucormycosis during March-July 2021 were included. Mucormycosis was diagnosed based on mycological confirmation on direct microscopy (KOH/Calcofluor white stain), culture, histopathology, or supportive evidence from endoscopy or imaging. After consent, trained data collectors used medical records and telephonic interviews to capture data in a pre-tested structured questionnaire. At baseline, we recruited 686 patients from 26 study hospitals, of whom 72.3% were males, 78% had a prior history of diabetes, 53.2% had a history of corticosteroid treatment, and 80% were associated with COVID-19. Pain, numbness or swelling of the face were the commonest symptoms (73.3%). Liposomal Amphotericin B was the commonest drug formulation used (67.1%), and endoscopic sinus surgery was the most common surgical procedure (73.6%). At discharge, the disease was stable in 43.3%, in regression for 29.9% but 9.6% died during hospitalization. Among survivors, commonly reported disabilities included facial disfigurement (18.4%) and difficulties in chewing/swallowing (17.8%). Though the risk of mortality was only 1 in 10, the disability due to the disease was very high. This cohort study could enhance our understanding of the disease's clinical progression and help frame standard treatment guidelines.

Prospective Evaluation of Hearing Status in Neonatal Hyperbilirubinemia.

Elevated bilirubin levels in neonates are commonly seen both physiologically and in pathological conditions. There are few articles describing the effects of elevated bilirubin levels on the auditory system. The objectives of this paper was to study the prevalence of hearing impairment in neonates with hyperbilirubinemia and assess outcome/reversibility of hearing impairment in these neonates with follow-up hearing evaluation. This was a prospective single centre, case control study. Cases: neonates, total bilirubin levels >15 mg/dl. Controls: <15 mg/dl. Exclusion criteria included neonates with neonatal hypoxia, intrauterine infections, sepsis or meningitis, infants with a family history of hearing loss, low birth weight, ototoxic medications, external and middle ear pathology. Otoacoustic emission testing (OAE) was done at birth. Neonates who fail OAE were advised follow up with Brainstem Evoked Response Audiometry (BERA) after 2 months. Neonates having abnormal BERA waves were called for follow up at 6 months. Out of 57 cases, 3 had failed OAE and had normal BERA waves on follow up at 2 months. Out of 60 controls, 5 had failed OAE and follow up BERA for 3 patients were normal and 2 babies were lost to follow up. No statistical significance in hearing impairment in hyperbilirubinemia v/s normal babies was noted. Elevated bilirubin levels in the absence of any other risk factors may not show significant changes in the hearing screening. Some effect owing to the p value close to being significant in cases has been noted. The same may not contribute to permanent hearing impairment as first OAE changes may be transient and seem to revert with age.

SMARCB1 (INI-1) - Deficient sinonasal carcinoma: Report of two cases.

SMARCB1 (INI-1)-deficient sinonasal carcinoma is a rare, poorly differentiated carcinoma defined by complete loss of tumor suppressor gene SMARCB1 (INI-1) within the neoplastic cell nuclei demonstrated by the immunohistochemical stain. SMARCB1 (INI-1) gene inactivation has been implicated in the pathogenesis of a diverse group of malignant neoplasms that tend to share "rhabdoid" morphology. SMARCB1 (INI-1)-deficient sinonasal carcinoma was first reported by Agaimy et al. in 2014. These tumors are often basaloid with focal rhabdoid differentiation, prominent necrosis, increased mitotic activity, and aggressive behavior. Other than being INI-1 and NUT negative, they are positive for pancytokeratin and express variable immunoreactivity for squamous markers like p63 and neuroendocrine markers like synaptophysin. Most patients present with locally advanced disease and hence a combination of chemotherapy, radiotherapy, and surgery is usually recommended.

Role of Total Laryngopharyngoesophagectomy with Gastric Pull Up in the Management of Locally Advanced Hypopharyngeal Cancers.

The current consensus in the management of hypopharyngeal cancers favors the non-surgical management. However, many studies have reported relatively better oncological and functional outcomes with the surgical approach in locally advanced hypopharyngeal cancers. In here, we report a tertiary care center's experience with total laryngopharyngoesophagectomy with gastric pull-up done for such cases. We also describe a slight modification of the procedure that has been followed at our institute, and discuss its advantages. It is a retrospective study of patients who have undergone the surgical procedure between the September 2016 and the March 2019. The primary objective was to analyze the surgical complications and the benefits in terms of disease clearance, survival duration, and functional outcomes. Study consisted of 15 patients, mostly men, with mean age of 56 years. 12/15 had stage IV disease and 7/15 were failed chemoradiotherapy. Most common complication of surgery was anastomotic failure (33%). Perioperative mortality rate was 13.3%. Higher complications could probably be attributed to poor nutrition and tension over the anastomosis. Mean survival duration and disease free interval were 12.1 and 11 months, respectively. Oral feeds was restored in 77%, and the average time to restore oral feeds was 17 days. Most of our results were comparable with the literature, which supports the surgical excision of larynx-pharynx-esophagus and reconstruction by pull-up, in all those medically fit cases of radio-recurrent/residual tumors, and also in primary cases of locally advanced hypopharyngeal cancers with non-functional larynx. In these scenarios, the radical surgical treatment would atleast serve as palliative if not curative.

Budesonide vs Saline Nasal Irrigation in Allergic Rhinitis: A Randomized Placebo-Controlled Trial.

OBJECTIVES: Budesonide nasal irrigation is currently widely used in the treatment of chronic sinusitis typically following endoscopic sinus surgery to improve inflammatory control. Its application in treatment of allergic rhinitis has not been previously studied. This study assesses the subjective and clinical response to budesonide buffered hypertonic saline nasal irrigation and hypertonic saline nasal irrigation in patients with allergic rhinitis. STUDY DESIGN: This is a prospective, single-center, double-blind, randomized placebo-controlled trial. SETTING: Tertiary care hospital. SUBJECTS AND METHODS: Fifty-two patients diagnosed with allergic rhinitis were randomized into 2 groups to receive either buffered hypertonic saline nasal irrigation with a placebo respule or buffered hypertonic saline nasal irrigation with a budesonide respule. Patients were assessed at baseline and 4 weeks subjectively using the Sino-Nasal Outcome Test-22 (SNOT-22) questionnaire and visual analog scale (VAS). Clinical assessment was done using the modified Lund-Kennedy score. RESULTS: The average SNOT-22, VAS, and modified Lund-Kennedy scores improved in both groups (P < .001). The budesonide irrigation group was found to have significantly better improvement than the saline nasal irrigation group with the SNOT-22 scores (P = .012) and VAS scores (P = .007). However, the difference in the clinical response between the 2 groups was not significant (P = .268). CONCLUSION: This study adds evidence to the use of saline nasal irrigation in allergic rhinitis but also demonstrates efficacy of the addition of budesonide to irrigations. Budesonide nasal irrigation thus appears to be a viable treatment option for allergic rhinitis.

Comparative Study of Nasal Symptoms and Pulmonary Function Tests Post FESS in Ethmoidal Polyposis.

The objective of this study were to assess the pulmonary function in patients with ethmoidal polyposis who did not respond to medical treatment; to evaluate the effect of Functional Endoscopic Sinus Surgery on the lung function of these patients and to compare the total nasal symptom score in these patients. A prospective observational study was conducted in Department of ENT, KMC Manipal on 50 subjects with ethmoidal polyposis who were unresponsive to medical treatment and hence underwent FESS. Pulmonary function tests were assessed using spirometry and nasal symptoms were scored as per TNSS system prior to surgery and 3 months post-surgery and compared with the pre-operative values and analysed. Pre operatively majority (35 patients) had TNSS value of 6-9 whereas post operatively the score was reduced to 2-3 in many patients (38 patients). The mean TNSS was 7.24 before surgery which declined to 2.82 after surgery with a p value < 0.0001 indicating a statistically significant improvement in the nasal symptoms post FESS. The mean pre-operative FVC, FEV1, MEFR were 2.94, 2.41 and 2.51 L respectively whereas the mean post-operative values were 2.95, 2.39 and 2.49 L respectively. There was no statistically significant change in lung function tests following FESS. Our study shows that FESS benefits patients with nasal polyposis by improving the symptoms and there by the quality of life without any adverse effects on the lower airways.

Sinonasal Metastatic Renal Cell Carcinoma: A Report of Two Cases with Varied Presentation and a Review of Literature.

Renal cell carcinoma is usually slow growing with delayed vague symptoms and may not be detected until an advanced stage. In only 9% of the cases the classical triad of "haematuria, costovertebral pain and abdominal mass" is seen. Less commonly, sinonasal metastasis may also be the presenting feature of RCC. So, in any case of sinonasal mass, possibility of metastasis from renal malignancy should be considered. Sinonasal metastasis from renal malignancy can occur even several years after the primary is treated with nephrectomy. In sinonasal region maxillary sinus is the most commonly affected. Isolated metastasis to the nose is extremely rare. Malignancies from various other sites of the body can also metastasize to sinonasal region. Epistaxis is the most common symptom. This is because of vascular stroma of the metastatic deposit. A 45 year old male with history of right nephrectomy 1 year back presented with intractable epistaxis. A 66 year old male presented with profuse epistaxis without any history of previous malignancies. Both the cases were evaluated resulting to the diagnosis of sinonasal metastasis from Renal Cell carcinoma. In the first case, metastasis occurred 1 year post surgery whereas in second case sinonasal metastasis was the presenting feature of Renal Cell carcinoma. Epistaxis is the most common symptom. This is because of vascular stroma of this metastatic deposit. In renal cancer, symptoms of metastasis often precede the symptoms of primary tumor.

Anatomical Variations of the Nose and Paranasal Sinuses: A Computed Tomographic Study.

To evaluate the anatomical variations in computed tomographic (CT) images of paranasal sinuses and to investigate association between them. DESIGN: Retrospective study. SETTING: Tertiary care center in the southern part of India. SUBJECTS: Radiological images of paranasal sinuses belonging to chronic rhinosinusitis patients managed between June 2016 and November 2018. METHODS: The studied characteristics in the CT images included the deviated nasal septum (DNS), concha bullosa (CB), Haller cell (HC), Onodi cell (OC), pneumatization of anterior clinoid process (ACP), pterygoid base (PB), superior turbinate, inferior turbinate, crista galli (CG), and nasal septum. The height of the lateral lamella of the cribriform plate, the sphenoid pneumatization pattern, and the optic nerve relationship with sphenoid sinus were studied separately. The associations between these factors, and with maxillary sinus opacifications were also investigated. A total of 151 adult patients' CT images were analyzed. The most common manifestations noted were DNS, CB and pneumatized PB, seen in 83.4%, 49% and 47% of the patients respectively. The rates of HC, OC, pneumatized septum, pneumatized CG, and pneumatized ACP were 39%, 23%, 27%, 43% and 27% in that order. Rates of most of these variations were within the range reported in the literature. Chi square test revealed that the OC was independently associated with pneumatized CG and pneumatized septum. The maxillary sinus opacification was related to DNS and CB, but not with protrusion of tooth root into the sinus. Most of the anatomical variations were comparable with the reports across the globe, however, the associations between these variations weren't common in our cohort.

Prevalence of HPV in Oral Squamous Cell Carcinoma in South West India.

There are inconsistent reports regarding the role of HPV in the origin and progression of oral squamous cell carcinoma (OSCC). The observed heterogeneity was mainly attributed to the social and cultural habits of the enrolled cases, discrepancies in the nature of samples procured and varying sensitivity of the assays employed for detection of HPV. The objective of this study was to assess the prevalence of HPV in OSCC in South West India. This was a cross sectional study conducted over a period extending from October 2015 to June 2017. This study involved Department of ENT-Head and Neck Surgery and Department of Virology, Manipal Academy of Higher Education. Fifty histologically confirmed oral squamous cell carcinoma patients undergoing wide local excision of the tumour were enrolled for the study. Intraoperatively 4-5 mm of tissue samples were transported in sterile normal saline at 4-80 °C. The primary screening of tissue samples was performed by nested PCR using PGMY09/11 consensus primers and GP5+/6+ consensus primers and TaqMan based real time multiplex PCR for HPV-16, HPV-18, HPV-31 and HPV-45. All samples tested negative for HPV DNA by conventional nested PCR and TaqMan based real-time Multiplex PCR ruling out four common HPV subtypes such as HPV-16, 18, 31, 45. We did not find presence of HPV DNA in the tissues of patients with OSCC from southwest India. However, studies with more geographic representation from other parts of India are required before generalising our findings.

Preoperative Staging of Differentiated Thyroid Carcinomas: Comparison of USG and CT with Intraoperative Findings and Histopathology.

To study the efficacy of USG and CECT in preoperative staging of differentiated thyroid carcinomas in comparison to the intraoperative and histopathological findings. A prospective, observational study was conducted in a tertiary care hospital over a period of one and a half years where USG and CECT of 23 subjects with histopathologically proven differentiated thyroid malignancy were analysed to study the characteristics of the primary tumour, lymphatic metastasis and evaluate the sensitivity and specificity of the radiological investigations in comparison to the intra-operative and histopathological findings. When compared with intraoperative and histopathological T-staging, USG had an accuracy of 69.5% and 73.9% and CECT had an accuracy of 78.2% and 73.9% respectively. The sensitivity and specificity of USG and CECT in determining a malignant nodule was 71.4% and 33.3% and 52.4% and 66.7% respectively. The N-staging according to the histopathological examination findings was in agreement with that of USG in 65.2% and CECT in 65.2% patients. The sensitivity and specificity of USG was 94.4% and 41.7% and that of CECT was 92.2% and 44.4% respectively in detecting lymphatic metastasis. The sensitivity and specificity of USG was 94.4% and 44.4% and that of CECT was 92.2% and 27.3% respectively in detecting lateral compartment lymphatic metastasis. USG identifies the characteristics of the malignant nodules better and CECT has a higher identifying central compartment lymphatic metastasis. CECT should be used as an adjunct to ultrasound to determine the extent of lymphatic metastasis and staging of disease.

A Retrospective Study to Assess the Role of Using Fine Needle Aspiration Cytology and Frozen Section in the Diagnosis of Thyroid Swelling.

The most cost-effective test is fine needle aspiration cytology (FNAC). Many surgeons use intraoperative frozen section to confirm the FNAC findings and to guide the extent of thyroid surgery. Though it is a valuable tool in the diagnosis of the thyroid lesion and determining the extent of thyroid surgery, still in certain cases diagnosis can be incorrect or inconclusive, so histopathology of the excised specimen remains the most reliable test. The purpose of this study will be to compare the result attained by FNAC and frozen section of the thyroid to the final histopathological diagnosis, in order to establish their role in thyroid surgery today. A retrospective study with a total of 140 patients who underwent thyroid surgery at the ENT department, of a tertiary hospital in coastal Karnataka. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated for FNAC and frozen section. The sensitivity, specificity, positive predictive rate, and negative predictive rate of frozen section was found to be 66.7%, 88.4%,76.6%, 82.4% respectively for detecting malignancy. This was found to be higher than the results of FNAC for the same which were 64.4%, 77.8%, 64.4%, 77.8% respectively. As the sensitivity of FNAC is similar to frozen section in detecting malignant cases, FNAC is a good tool for screening the patient for determining malignancy in thyroid, but frozen section is more specific in confirming the malignancy.

Nasal septal schwannoma: a rare sinonasal tumour with certain peculiarities.

Sinonasal schwannomas constitute 4% of head and neck nerve sheath tumours; however, schwannomas involving the nasal septum are quite rare. We present a 57-year-old male patient with nasal septal schwannoma who was managed successfully by endoscopic excision. 32 cases of septal schwannoma have been reported so far in the literature. This report discusses certain peculiar features exhibited by schwannomas of the nasal septum. Septal schwannoma does not show any age, sex or side predilection. However, they tend to involve posterior part of the septum and presumed to arise from the nasopalatine branch of the trigeminal nerve. Imaging findings of the sinonasal schwannoma are non-specific, but the histopathological characteristics are diagnostic, with seldom need for immunohistochemistry. Endoscopic excision is the safe and effective treatment option for the septal schwannoma of any size and location. Recurrence has not been reported in the literature following endoscopic excision.

Rhinofacialentomophthoromycosis.

Entomopthoromycosis is a rare subcutaneous fungal infection caused by onidiobolus coronatus affecting mainly the upper respiratory mucosa in immunocompetent people.The manifestations of this disease masquerades other clinical entities.Hence, high index of suspicion is required for prompt diagnosis.Histopathological examination and culture are the gold standard diagnostic tools, however no standard treatment protocols ha been mentioned in literature.We present a case of rhinofacial entomopthoromycosis in a yearold ma with a leftsided rhinofacial swelling to highlight the presence of this unusual fungal infection and its treatment.

Benign Lymphoepithelial Cyst of the Parotid in HIV Negative Patient.

Benign lymphoepithelial cysts are slow growing tumours commonly seen in HIV positive adults. It is rare to find them in non HIV individuals. In this article we discuss an uncommon presentation of a parotid swelling occurring in a 49-year-old non HIV male, which was diagnosed as benign lymphoepithelial cyst. The various investigative modalities and treatment options are outlined in this article.

Ganglioneuroblastoma of Skull Base.

Neuroblastic tumours are common in childhood and adrenal glands are the most common site. Head and neck ganglioneuroblastomas are extremely rare and nose is a very uncommon site for a ganglioneuroblastoma. The management of this primitive sympathogonic tumour may vary depending on the age of the patient and stage of the tumour. We present a middle-aged man with a ganglioneuroblastoma of skull base, management of this tumour and a review of literature.

Recurrent angioleiomyoma of the middle turbinate.

We present a case of a middle-aged woman with a history of not only progressive nasal obstruction, facial pain, hyposmia and epistaxis, but also excision of the nasal mass diagnosed as a vascular leiomyoma. On examination, a smooth bulge was seen over the middle turbinate. Surgical excision along with histopathology and immunohistochemistry revealed a diagnosis of recurrent vascular leiomyoma of the middle turbinate.

Sclerosing lipogranuloma of the eyelid: unusual complication following nasal packing in endoscopic sinus surgery.

An eyelid or orbital lipogranuloma can occur following nasal packing with liquid paraffin, petroleum jelly or an antibiotic-based cream. It usually presents a few weeks or months after the initial procedure. We present a report of three such cases of sclerosing lipogranuloma involving the eyelid, which occurred following a sinonasal surgery where nasal packing using petroleum jelly was performed. The typical clinical course and the classical histopathological features are highlighted. All cases were diagnosed by histopathological examination as sclerosing lipogranuloma. Complete surgical removal resulted in complete resolution on 1 month follow-up. The diagnosis is based on a high degree of suspicion following a detailed history of prior use of lipid-based products for nasal packing following endonasal surgery. Histopathology is diagnostic. Surgical excision is the treatment of choice, however, due to its infiltrative nature, it may be difficult to obtain a complete cure.

Amelanotic malignant melanoma of the cervical oesophagus.

We report the case of a young woman who presented with progressive dysphagia and swelling in the anterior aspect of the neck of short duration. On evaluation, she was diagnosed with amelanotic malignant melanoma of the cervical oesophagus. She underwent total laryngopharyngo-oesophagectomy with gastric transposition with bilateral modified radical neck dissection with feeding jejunostomy and a permanent tracheostomy with postoperative combined chemoradiation therapy. However, in spite of aggressive treatment, the patient expired 8 months after initial presentation with distant metastasis.

Juvenile aggressive cemento-ossifying fibroma of the sphenoid sinus with proptosis: a surgical dilemma.

The term fibro-osseous lesion has currently grown in popularity as an overall designation for a number of rare, histologically benign head and neck lesions that are made up of bone, fibrous tissue and cementum. Cemento-ossifying fibroma is a variant of cementifying fibroma and is a fibro-osseous disease. They are usually small innocuous lesions which follow a slow benign course and are commonly seen in the skull bone rather than the sphenoid. It is rare for these tumours to attain large size, behave aggressively, destroy bone and require a radical surgery. One such rapidly growing juvenile cemento-ossifying lesion of sphenoid in our 10-year-old young patient causing proptosis and impaired vision is reported here because of its uncommon nature and its surgical dilemma. Selection of surgical approach to resect this tumour becomes difficult because it is deeply seated and needs a multidisciplinary approach.

Endoscopic approach to middle turbinate squeeze syndrome.

Middle turbinate squeeze syndrome (MTSS) refers to sino-nasal headache due to intense contact between the middle turbinate and the nasal septum and/or between middle turbinate and other structures in the lateral nasal wall. This study was intended to evaluate the efficacy of precise endoscopic surgical treatment of MTSS. This is a prospective study of 126 patients with refractory cephalgia due to endoscopically confirmed MTSS who underwent functional endoscopic naso-sinus surgery (FENS) wherein the contact points and ostio-meatal complex obstruction were endoscopically relieved. 91% of cases reported improvement/resolution of headache and 95% of cases had relieved contact points as documented endoscopically. This surgery was also found to facilitate resolution of sinus disease, both radiologically (in 64% of cases) and endoscopically (in 94% of cases). Cephalgia caused by MTSS can be effectively treated by an ultra-conservative endoscopic approach.
