Etizolam is a thienodiazepine derivative which produces an anxiolytic effect similar to benzodiazepines such as alprazolam (Xanax). Like classic benzodiazepines, etizolam has a high affinity towards the GABAA receptor, and allosterically potentiates the effects of GABA resulting in neuronal hyperpolarization related to chloride influx. When taken in therapeutic doses, etizolam produces a similar effect to Xanax. Counterfeit Xanax tablets contain variable amounts of etizolam. Tablets with high amounts of etizolam can cause toxicity if ingested, especially when combined with other substances. When toxic symptoms occur in patients, they may include severe sedation, unconsciousness, and depression of the medullary respiratory center. …

Dysplasia In Oral Lichen Planus In A Sample Of Egyptians Attending 2 Tertiary Care Centers In Cairo, Dalia Ghalwash, Ayman El-Gawish

Dentistry

The present retrospective study aimed to evaluate dysplastic changes in oral lichen planus (OLP) lesions and related risk factors in a sample of Egyptians. The records of patients with histological diagnosis of OLP, who attended the Oral Medicine and Periodontology Department, Faculty of Dentistry, Cairo University, and Faculty of Dentistry, the British University in Egypt, in the period from 2020 to 2023 were used. The frequency of dysplasia was 10.19% and was statistically not associated with age, gender or smoking. Our results showed that the erosive type registered the highest rate (p<0.001), followed by atrophic, whereas papular type did not show dysplasia. Also, the most common site for dysplasia was the buccal mucosa and tongue (p<0.001 and p=0.001, respectively), then gingiva, lips, and floor of the mouth. Given the importance of OLP, among the Egyptian population seeking care in our clinics, more research should be conducted to create a database of statistical information.
