Is there a correlation between viral load and olfactory & taste dysfunction in COVID-19 patients?

OBJECTIVES: To evaluate the correlation between cycle threshold (Ct) value and occurrence of olfactory and taste dysfunction in COVID-19 patients. METHODS: This comparative study included COVID-19 patients diagnosed by reverse transcription- polymerase chain reaction (RT-PCR) based test at our hospital with mild to moderate disease. The demographic details and detailed clinical history of the patient, including history of loss of smell and taste was taken at the time of presentation. The patients were divided into 2 groups, group A: COVID-19 patients with OTD; group B: COVID-19 patients without OTD. 100 contiguous patients were recruited in each group. The COVID-19 test by RT-PCR was done and Ct value of the 3 genes: E (Envelope encoding) gene, N (Nucleocapsid encoding) gene, and RdRp (RNA-dependent RNA polymerase) gene, was used for data analysis. The Ct values of each of the three genes were compared between groups A and B. RESULTS: Group A and B did not differ significantly in terms of basic demographics. The differences in the Ct values of the 3 genes E gene, N gene and RdRp gene, of group A and B were found to be statistically significant (p = 0.005, p = 0.001 and p = 0.002, respectively). CONCLUSION: The patients with OTD had a lower Ct value at diagnosis, and hence, a higher viral load than those without OTD. The evaluation of Ct value and viral load in COVID-19 patients may help in further reducing the transmission of the virus in the community.

Association of temperament with dental anxiety and behaviour of the preschool child during the initial dental visit.

The aim of this study was to investigate whether there is an association between temperament characteristics of preschool children, dental anxiety, and their dental behaviour. A total of 100 children, aged 3-5 yr, who were attending their initial dental visit accompanied by a parent, were included in this cross-sectional study. Dental anxiety of children was measured using the Facial Image Scale. The behaviour of children during the initial oral examination and oral prophylaxis was assessed using Frankl's behaviour rating scale. Temperament was assessed using Emotionality, Activity, Shyness Temperament Survey for Children (parental ratings). Statistically significant weak linear positive correlations were seen between the following: the percentage duration of definitely negative behaviour and shyness scores (rs  = 0.28); anxiety level and emotionality scores (rs  = 0.28); and anxiety level and shyness scores (rs  = 0.26). Multinomial logistic regression analysis revealed that children with higher anxiety had higher odds of showing definitely negative behaviour, which decreased with increasing age of the child. Emotionality and shyness temperaments may be weakly associated with dental anxiety, and shyness may be weakly associated with the dental behaviour of the preschool child. Definitely negative dental behaviour is associated with dental anxiety and age of the child.

Removal of an Unusual Neglected Foreign Body in Infratemporal Region Using Navigation.

A 19-year-old male presented with complaint of a bluish mass in the hard palate since 3 months. The patient had a history of trauma 8 years back in the left zygomatic area with a pen. It was lodged in the wound and removed at that time. Computed tomography scan was revealed a linear heterogenous dense structure extending from left infratemporal fossa to oral cavity, traversing through left maxillary sinus, with bone defect seen in lateral and medial wall of maxilla, and in the hard palate, most likely a neglected foreign body. The foreign body was removed by navigation-assisted endoscopic surgery and the palatal perforation repaired using local rotation flap. There were no intraoperative or postoperative complications. Navigation-guided removal of foreign body in proximity to vital structures, in the infratemporal region, is a valuable option with minimal morbidity.

Alveolar Rhabdomyosarcoma of the Temporal Region with Metastatic Cervical Lymph Node.

Introduction: Paediatric rhabdomyosarcoma most commonly occurs in the head and neck region. Its treatment is complex, including multi-drug chemotherapy, surgery and radiotherapy. Case report: Here, we report a case of alveolar rhabdomyosarcoma of the temporal region with a metastatic cervical lymph node, in a 15-year-old girl, and its management. The patient received ne-adjuvant chemotherapy, followed by surgery and post operative radiotherapy. Literature was also reviewed for the various treatment modalities for these rare tumours. Discussion: Rhabdomyosarcoma of the temporal region has rarely been reported in the literature. Due to the rarity of these tumours, there are difficulties in creating standardized therapeutic protocols. However, multimodality treatment, including chemotherapy, surgery and radiotherapy, has been shown to improve the overall survival rate.

Spheno-Orbital Tuberculosis: A Rare Case.

A 9-year-old girl presented with progressive, painless protrusion of the right eye for 2 months. She also complained of multiple bilateral neck swellings for 2 months. On examination, there was proptosis of the right eye with the eyeball displaced downwards and forwards. The extra ocular movements of the right eye showed limitation of abduction. The vision was normal in both eyes. A detailed clinical evaluation with investigations led to a diagnosis of spheno-orbital tuberculosis. Prompt initiation of anti-tubercular therapy (ATT) led to resolution of the lesion.

A Correlation of Tumour Budding and Tumour-Stroma Ratio with Clinicopathological Factors in Oral Squamous Cell Carcinoma.

Objectives: This study aimed to analyse the association of tumour budding (TB) and tumour-stroma ratio (TSR) with clinicopathological parameters that can be easily viewed on routine haematoxylin and eosin (H&E)-stained slides to provide an easy and cost-effective method for prognosticating oral squamous cell carcinoma (OSCC). Methods: This study was conducted at the ESIC Medical College and Hospital in Faridabad, India, from July 2022 to October 2022. In patients with histologically diagnosed OSCC, TB and TSR were evaluated via routine H&E-stained sections and correlated with clinicopathological parameters. Statistical analysis was performed using Chi-squared test. Results: A total of 50 patients were included. The mean age of participants was 61 ± 12.72, and the male-to-female ratio was 7.1:1. Most of the tumours were located on the tongue (46%), followed by the buccal mucosa (26%), gingivobuccal sulcus (12%) and retromolar trigone (8%). The palate and alveolus were the other sites involved, constituting 4% each. TB and TSR were both found to be significantly associated with the tumour grade, lymph node metastasis and tumour size. A highly significant correlation was also found between TB and TSR (P = 0.001). Conclusions: Both TB and TSR can be easily evaluated on routine H&E sections; they are highly reproducible and were found to be reliable independent prognostic markers in OSCC. Therefore, this simple and cost-effective method of prognostication, which is currently lacking in clinical practice, will help clinicians to identify patients with poor prognosis and thus individualise their treatment plan.

Monoarticular carcinomatous knee joint arthritis as an initial presentation of cervical carcinoma.

When it comes to cancer, one can expect the unexpected. The clinical presentations can be very bizarre. One of these uncommon presentations is monoarticular arthritis. The age group affected by cancer and arthritis are similar. However, the possibility of joint pain being secondary to metastatic involvement does not come to mind easily. In this report, a 65-year-old postmenopausal woman presented with complaint of pain and restricted movement of the right knee joint, in whom the clinical and magnetic resonance imaging features were suggestive of infective monoarthritis. However, synovial fluid aspirate showed presence of malignant cells. Hence, patient was evaluated with whole-body (18)F-fluorodeoxyglucose positron emission tomography computed tomography which detected primary malignancy of the cervix with regional nodal and right knee joint metastasis. To our knowledge, this is the first reported case of cervical malignancy with solitary skeletal metastasis involving the knee joint. The report also discusses overall incidence of malignant arthritis.

MRSA Causing Necrotizing Fasciitis in 18-Month-Old Boy.

Necrotizing fasciitis is a rare and fulminant infection of the superficial fascia and subcutaneous cellular tissue. It is commonly polymicrobial, with the combination of aerobic and anaerobic bacteria, which contributes to the rapid progression and severity of the disease. The microbes commonly involved include group A streptococcus, Enterobacteriaceae, anaerobes, and Staphylococcus aureus. Over the past few years, skin and soft tissue infections, including necrotizing fasciitis, due to methicillin-resistant Staphylococcus aureus are increasing.

Infantile Fibrosarcoma of the Tongue Base.

Infantile fibrosarcoma is an uncommon soft tissue tumour in infants and children mostly located in the extremities. Its occurrence in the head and neck, particularly in the oral cavity is extremely rare. Here, we report a case of infantile fibrosarcoma of the tongue base in a 9-year-old boy and discuss the complexities in arriving at diagnosis and its management. The patient underwent wide local excision of the tumour. Histopathology was essential in confirming the diagnosis. As per search in English literature, this is the first case of infantile fibrosarcoma of the tongue base to be reported till date. Treatment of choice is wide local excision with or without chemotherapy.

Sarcomatoid Carcinoma of Larynx: A Rare Case.

Sarcomatoid carcinoma is a rare tumour consisting of both sarcomatous and carcinomatous elements. It accounts for less than 1% of laryngeal malignancies. This case report describes sarcomatoid carcinoma of the larynx in a 54-year-old male managed by total laryngectomy with post operative radiotherapy. Surgery is the treatment modality of choice for this rare entity. However, early stage sarcomatoid carcinoma tumours are better treated with radiotherapy alone similar to early stage squamous cell carcinoma of the larynx with favourable results.

Anosmia: A Clinical Indicator of COVID-19 Reinfection.

COVID-19, an ongoing world pandemic, is caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). Many organizations have recognized that COVID-19 patients may have sudden loss of smell or taste and have included these symptoms in their diagnostic guidelines. However, the occurrence of anosmia and dysgeusia in COVID-19 reinfection is yet to be ascertained.

Loss of smell and taste in COVID-19 infection in adolescents.

OBJECTIVES: To study the prevalence, clinical course and outcomes of olfactory and taste dysfunction in COVID-19 positive adolescents. METHODS: This prospective study was carried out from May to August 2020. The adolescents, aged 10-19 years, who were detected COVID-19 positive by RT-PCR with mild to moderate disease were included in the study. The following epidemiological and clinical outcomes were studied: age, sex, general symptoms, olfactory and taste dysfunction. RESULTS: Out of 141 patients included in the study, there were 83 males (58.9%) and 58 females (41.1%). The age varied from 10 to 19 years with an average of 15.2 years. Forty patients (28.4%) had olfactory or taste dysfunction. Out of these 40 patients, 28 patients (19.8%) had both olfactory and taste dysfunction. Of the 34 patients (24.1%) who complained of olfactory dysfunction, 16 patients complained of hyposmia and 18 patients complained of anosmia. Dysgeusia was reported by 34 patients (24.1%). The duration of OTD varied from 2 to 15 days with an average of 5.7 days. CONCLUSION: Loss of smell and taste are common symptoms in COVID-19 positive adolescents. It recovers spontaneously within a few weeks, along with the resolution of other symptoms.

Giant Cell Tumour of Temporal Bone and Infratemporal Fossa: A Rare Case.

Giant cell tumours (GCT) of the bone are uncommon primary bone neoplasms that occur mainly in the epiphysis of long bones. GCT of the skull is rarely encountered, particularly of the temporal bone. We report a rare case of giant cell tumour of the squamous portion of the temporal bone extending to the infratemporal fossa in a 38-year old male. The patient presented with progressive trismus, and swelling and pain in the right temporal region. The patient underwent excision of the mass by maxillary swing approach. The treatment of choice for GCT is complete surgical excision. Based on the location and extent of the GCT in the infratemporal fossa, several surgical approaches have been tried for its excision.

Paediatric nasal dermoids: Our experience.

OBJECTIVES: Nasal dermoids are rare developmental anomalies seen in children. This study reports our experience in a developing country of the clinical and radiological findings as well as the management of nasal dermoids. METHODS: A retrospective analysis was performed, from 2012 to 2017, for 10 patients admitted for the treatment of nasal dermoids at a tertiary care center. The clinical presentation, preoperative imaging (CT/MRI), surgical approach, intraoperative findings, complications and recurrence were reviewed. RESULTS: Ten patients were included in this study, 6 males and 4 females, with an average age of 10.2 years at the time of presentation. Three patients presented with a mass located on the nasal dorsum, 1 had a nasoglabellar mass, 2 patients had a mass located on the nasal dorsum with visible sinus, and 4 patients presented with a sinus on the nasal dorsum, in which 1 patient had a tuft of hair. CT was performed in all the cases. It was not suggestive of intracranial extension in 9 patients, and was non-diagnostic in one patient. Both CT and MRI were performed on 2 patients, with no evidence of intracranial extension. Surgical and radiological findings were concordant in 8 patients (80%). CONCLUSION: Nasal dermoids require preoperative imaging and precise surgical planning to achieve complete removal.

Epidemiological Profile of ENT Emergencies: Our Experience.

Emergencies in otorhinolaryngology are common occurrence. Early diagnosis and management result in reduction in morbidity and mortality. To assess the epidemiology, pattern and distribution of ENT emergencies at a tertiary level hospital. Cross sectional, retrospective, descriptive study over a period of 5 years. Medical records of these patients were studied, noting the age, sex, diagnosis on admission and outcome of emergency care. A total of 38,793 patients, age ranging from 15 days to 85 years were included in the study. The number of male and female patients were 25,971 (66.95%) and 12,822 (33.05%) respectively and the male to female ratio 2:1. The most commonly encountered emergency was epistaxis, which accounted for 25.58% of the emergencies attended. This was followed by ear ache and ear discharge. The ENT emergency ward plays a key role in the management of life-threatening conditions requiring immediate evaluation and management by specialized physician. It is important to prioritize and reduce the number of non-urgency/emergency cases attending the emergencies in order to ensure proper care is given to the emergency cases.

Baseline Pancreatic Beta Cell Imaging After Pancreatic Transplantation Using Whole-Body 68Ga-DOTA-Exendin-4 PET/CT: A Spectrum of 2 Cases of Diabetes Mellitus.

Whole pancreatic transplant and islet cells transplantation are currently available strategies aiming toward diabetes cure. Beta cell specific noninvasive functional imaging using novel PET radiotracers are now available and can be used for beta cell imaging and quantification. Herein we describe a spectrum of 2 cases demonstrating beta cell targeted imaging using Ga-DOTA-exendin-4 PET/CT in patients with diabetes after simultaneous pancreas-kidney transplantation.

Internal Carotid Artery Bleed: A Rare Complication of Invasive Sphenoidal Aspergillosis.

BACKGROUND: Invasive sinonasal aspergillosis is rarely seen in immunocompetent individuals. It may involve adjacent intracranial and intraorbital structures causing high morbidity and mortality. CASE DESCRIPTION: We report a rare case of invasive Aspergillus sinusitis in a young, immunocompetent woman causing headache and vision loss. Endoscopic débridement under general anesthesia was complicated by rupture of a mycotic cavernous carotid artery aneurysm. This was managed by packing with muscle and fascia followed by endovascular coiling. Subsequently, the aneurysm extended intradurally and caused fatal subarachnoid hemorrhage. CONCLUSIONS: This case emphasizes the need for early diagnosis of invasive fungal sinusitis to prevent intracranial complications and fatal outcome. When the diagnosis is made, aggressive treatment with surgical débridement and adjuvant antifungal therapy is required. Internal carotid artery involvement is a rare but life-threatening complication of invasive fungal sinusitis.
