Background: There has been a dramatic change in the pattern of patients being seen in hospitals and surgeries performed during the ongoing COVID-19 pandemic. The objective of this study is to study the change in the volume and spectrum of surgeries performed during the ongoing COVID-19 pandemic compared to pre-COVID-19 era. Methods: Details of all patients who were operated under department of neurosurgery at our institute since the onset of COVID-19 pandemic in India were collected and compared to the same time period last year. The demographic profile, diagnosis, surgery performed, type of surgery (routine/emergency, cranial/ spinal and major/minor) in these two groups were compared. They were further categorized into various categories [neuro-oncology (brain and spine tumors), neuro-trauma (head injury and spinal trauma), congenital cases, degenerative spine, neuro-vascular, CSF diversion procedures, etc.] and compared between the two groups. Results: Our study showed a drastic fall (52.2%) in the number of surgeries performed during the pandemic compared to pre-COVID era. 11.3% of patients operated during COVID-19 pandemic were nonemergent surgeries compared to 57.7% earlier (p = 0.000). There was increase in proportion of minor cases from 28.8% to 41.5% (p = 0.106). The proportion of spinal cases decreased from 27.9% to 11.3% during the COVID-19 pandemic (p = 0.043). Conclusions: The drastic decrease in the number of surgeries performed will result in large backlog of patients waiting for 'elective' surgery. There is a risk of these patients presenting at a later stage with progressed disease and the best way forward would be to resume work with necessary precautions and universal effective COVID-19 testing.

Xanthogranulomatous pyelonephritis is a relatively rare entity that is associated with obstruction, stones and infection of the urinary tract. Late presentation leads to loss of renal parenchyma. It cannot be differentiated preoperatively with renal tumours (renal cell carcinoma and Wilms' tumour), pyonephrosis, infected hydronephrosis and renal lymphoma. Nephrectomy and antibiotics are the treatment of choice.

This study has demonstrated for the first time the important role of joint orientation and its correlation with the severity of BI and AAD and has described new joint indexes.

Lingual mucosal graft harvesting is feasible, provides a long graft, is easy to carry out and is the least morbid procedure.
