Objective: Chest CT has higher sensitivity in comparison to reverse transcription-polymerase chain reaction (RT-PCR) for COVID-19 diagnosis. We aim to identify the association of CT severity scores (CTSS) with lab markers and the need for oxygen. Methods: Cross-sectional observational study of 104 COVID-19 RT-PCR positive hospitalized patients. Patients underwent pulmonary CT, and their CTSS was calculated. SpO2, D-dimer and C-reactive protein (CRP) were also measured. The data was then collected and analyzed. Results: CT Severity Score (CTSS) was higher in patients above 50 years of age and males, though statistically insignificant. CTSS was positively correlated with D-dimer (p = 0.048) and oxygen requirement (0.000). However, HbA1C was lower in patients with higher CTSS. Conclusion: High CTSS correlates well with oxygen requirement, low SpO2, and high D-dimer but not with CRP and HbA1C. Our data suggest that CTSS can help predict disease outcomes by assessing disease severity.

Aim: The purpose of this survey is to assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on dental education in the state of Rajasthan. Materials and methods: An online questionnaire was circulated through Google forms for a period of about 3 months to both the postgraduate (PG) and undergraduate (UG) dental students of Mahatma Gandhi Dental College & Hospital, and the chain referral sampling method was followed to recruit more participants in this survey. The dental students participated in the study via the internet. Results: Among the 302 students that participated, 60.3% participants were females, 39.7% were males, 38.1% participants were PG students, and 61.9% were UG students. Female participants (74.2%) had greater difficulty in selecting the webinars than male participants (67.5%) (p = 0.028). The physical health of female participants was more impacted than males (p = 0.014). PG students are in more dilemma in choosing the webinars than UG students (p = 0.033). The UG students (31.6%) agreed more with the statement that the online exams/assessments were effective compared to PG students (23.5%) (p = 0.020). Conclusion: There is an indication that the students have been negatively affected by the pandemic. The shift to online learning is not greatly accepted by most of them, whereas some have adapted to the transient use of technology in the curriculum. In addition, one of the majorly impacted areas is the underdevelopment of their hands on skills.

Most facial palsies are lower motor neuron lesions. Occasionally, however, an isolated facial palsy is seen, which appears to be upper motor neuron in nature. Computed tomography demonstrated small deep infarcts in the internal capsular/corona radiata regions. Pure upper motor neuron facial palsy may be another lacunar syndrome due to a lesion in the internal capsule or corona radiata.

Protein losing enteropathy (PLE) describes a diverse group of disorders associated with excessive loss of serum proteins into the gastrointestinal (GI) tract. This excess protein loss leads to hypoproteinemia and may be manifested by edema, ascites, and malnutrition. This case of a rare condition, primary intestinal lymphangiectasia leading to protein loss, is being reported to highlight the clinical features and presentation of these disorders as they are easily detectable and treatable, and many can be cured.

Basilar artery occlusion is rare, accounting for approximately 1% of ischemic strokes characterized by pons and cerebellum infarction. Symptoms range from paresthesia and oculomotor symptoms to locked-in syndrome. Here, we report a rare case of basilar artery infarction in a 79-year-old female patient who presented with a right-sided lower motor neuron-type facial nerve palsy. This case is being reported to highlight the neuroimaging and clinical features of this condition.

Metronidazole is an antibiotic and an antiprotozoal drug very commonly used in our day-to-day practice. It is generally well tolerated and common vomiting, abdominal cramps, and metallic taste. We are presenting a rare case of metronidazole-induced cerebellar ataxia in a patient who received the drug for a relatively shorter duration. The neurological features usually occur when the drug dose exceeds 2 gm/day for a prolonged period. Peripheral neuropathy, dizziness, encephalopathy, seizures, and optic neuropathy can be seen. Cerebellar ataxia is a rare and serious side effect of this drug.

Background: Mandibular advancement device (MAD) has been described as an alternative treatment to severe obstructive sleep apnea (OSA), but it is not as effective as continuous positive airway pressure (CPAP) therapy in reducing the apnea-hypopnea index (AHI). Case description: We report a case of a 55-year-old male who presented with moderate sleep apnea. Polysomnography report shows an AHI score of 50 which is diagnosed as severe sleep apnea. MAD was planned for the treatment of sleep apnea. Conclusion: Mandibular advancement device (MAD) resulted in an increase in the upper airway space. This ultimately helped in the therapeutic treatment of snoring and improved quality of life.

Aim: To rehabilitate a patient of microstomia in need of a fixed dental prosthesis. Background: Microstomia, is a common terminology used for patients with restricted mouth opening. It may be caused by any damage to the facial nerve and subsequent fibrosis on facial muscles on the affected side. Patients with restricted mouth opening have difficulty maintaining oral hygiene due to limited access. Hence, dental decay and periodontal problems have been found to be prevalent in the affected population. Case description: A 42-year-old female patient reported to the Department of Prosthodontics Crown & Bridge at Mahatma Gandhi Dental College & Hospital, Jaipur, Rajasthan, India, with a chief complaint of pain in her lower right back tooth for the last 2 months. The patient gave a medical history of a parotid tumor on the right side of her face, behind her ear, which was excised at the age of 15 and led to facial nerve paralysis along with restricted mouth opening. On extraoral examination, it was observed that the patient had gross facial asymmetry on the right side. Conclusion: The present case report describes simplified locking designs of the tray segments, which could be used for both dentulous and edentulous patients for the fabrication of custom trays. Using the pin-lock method of tray fabrication stated in this case report, a clinician can make an accurate impression with increased ease. The method described in the report is not only comfortable for the patient but also yields accuracy and precision. Clinical significance: Using the pin-lock method of tray fabrication stated in this case report, a clinician can make an accurate impression with increased ease.
