Coronavirus disease has taken a toll on everyone's lives either physically or emotionally throughout the world. One of the most serious complications occurring currently in covid-positive and recovered patients is the deadly invasive mucormycosis. There are five clinical types of mucormycosis, out of which rhino-orbito-cerebral is the most common form (44%–49%). Management includes early diagnosis, control of the underlying diseases, and aggressive medical and surgical intervention. In patients undergoing maxillectomies, the use of immediate surgical obturators has become the gold standard. The rationale for its use is threefold—functional (matrix for the surgical dressing; allows the patient to speak and swallow), hygienic (separates the maxillary surgical site from contents of the oral cavity), and psychological (restores patient's self-image by reproducing lost oral structure). This article includes two case reports of patients diagnosed with rhinocerebral mucormycosis. The surgical debridement, medical management, and immediate reconstruction using palatal obturators have been explained.

From ancient time Calotropis gigantean has lots of beneficial effects already reported, but in this research work two different concentration of plant methanolic extracts showed remarkable anthelmintic activity against India earthworms Pheretima posthuma. The result was also compared by standard drug Albendazole and Carboxy Methyl Cellulose (CMC) as a control group. Here we also find out the phytochemical constituent of this plant.

Objective: To investigate the effects of folic acid on testicular oxidative damage in sodium fluoride-induced male Wistar rats. Methods: A total of 24 male Wistar rats were divided into 4 groups: the control, sodium fluoride (fed with 100 mg/L sodium fluoride through drinking water orally for 21 days), folic acid (36 μg/kg body weight/day, orally), and sodium fluoride plus folic acid (received similar dose orally) groups. At the end of 21 days, epididymal sperm parameters, biochemical analysis of testicular tissue, and serum hormonal levels were performed along with histopathological studies. Results: Sodium fluoride intoxication resulted in marked reduction in gonado somatic index, serum luteinizing hormone, and testosterone level along with 3 β -hydroxysteroid dehydrogenase and 17 β -hydroxysteroid dehydrogenase activities. In addition, reduction in sperm density, as well as loss of sperm motility and sperm viability, were also observed. Besides, increased levels of testicular malondialdehyde, nitrite, interleukin-6 and tumor necrosis factor- α as well as decreased levels of superoxide dismutase and catalase activities and reduced glutathione content were found to be associated with this toxicity. Folic acid co-treatment, on the other hand, could prevent all the sodium fluoride-induced testicular pathophysiology and oxidative stress related parameters. Histological examinations of testicular sections from the experimental rats supported these results. Conclusions: Combining all, this study suggests that being an antioxidant, folic acid plays a beneficial role against fluoride-induced adverse effects on the male reproductive system.
