A Study of Incidence and Management of Postoperative Hypocalcemia in Patients Undergoing Near-Total and Total Thyroidectomy

To study the incidence and management of postoperative hypocalcemia in participants undergoing near-total (NTT) and total thyroidectomy (TT) at a tertiary health care center. This is an observational prospective study. Patients posted for NTT and TT in our institute and meeting the inclusion criteria were included. A total of 45 participants were enrolled. The serum calcium was measured on postoperative day 2, at the time of discharge and on 3 months follow-up. A combination of injectable and oral calcium supplements with or without vitamin D sachet was used for the treatment of hypocalcemia. Hypocalcemia was observed in 49% cases. Women were observed to develop hypocalcemia at a higher rate than men. Incidence of hypocalcemia was more in TT patients than NTT patients. Cases with malignant pathology were more susceptible to develop hypocalcemia than those with benign pathology. Operated TT with concomitant neck dissection were at higher risk for development of hypocalcemia. There was no significant association between age and incidence of hypocalcemia. Serum calcium measured on postoperative day 2 was a reliable indicator of risk of hypocalcemia. The early measurement of serum calcium level is a reliable indicator of the risk of hypocalcemia. Standardized treatment of hypocalcemic patients with calcium and vitamin D supplements can reduce the incidence and morbidity associated with postoperative hypocalcemia.

Epidemiology, Clinical Features and Management of Rhino Orbital Mucormycosis in Post COVID 19 Patients

COVID 19 infections may be associated with a wide range of bacterial and fungal co-infections. Mucormycosis is a fungal infection primarily affecting immunocompromised individuals. We have observed sudden rise of mucormycosis cases in post COVID 19 patients. Here we have reported 100 cases of mucormycosis associated with COVID 19. To study epidemiology and clinical features of rhino orbital mucormycosis in post COVID 19 patients. To evaluate efficacy of medical as well as surgical treatment in such patients. This was an observational mixed (retrospective + prospective) study with a duration of 2 months. After noting demographic data, necessary radiological investigation was advised and representative tissue was sent for KOH and histopathological examination. Medical and surgical treatment was planned accordingly. Most patients (55%) presented with complaint of headache and facial pain. Hard palate involvement was observed in 45% patients. Unilateral presentation (68%) was more common. Only 25% patients who presented early had normal vision. We reported 22 patients with complete loss of vision. Eye movements were restricted in 58% patients. Diabetes mellitus is most common predisposing factor (65%). 9 patients required orbital exentration. Only 18% patients required Amphotericin for more than 14 days. Immune dysregulation caused by COVID 19 infection in addition to widespread use of steroids and broad-spectrum antibiotics may lead to the development mucormycosis. Diabetes Mellitus type II is another important risk factor and the presence of both have additional effect in causing mucormycosis. Headache and facial pain should be considered highly suspicious of mucormycosis. Early diagnosis with efficient treatment can improve prognosis.

Ototoxic effects of irradiation

In this study ototoxic effect of ionizing radiation was studied in 70 ears with minimum follow up of 6 months post radiotherapy. Patients of nasopharyngeal carcinoma and with conductive deafness pre radiotherapy were excluded from the study to eliminate mechanical obstruction that may play role in Eustachian tube dysfunction. We found that Eustachian tube dysfunction and conductive deafness were reversible where as Sensorineural hearing loss was an irreversible effect of radiotherapy. Dose of radiation was directly proportional to ototoxicity, minimum 60 Gys of total radiation dose was required to produce significant ototoxicity.
