However, since the establishment of its role in cell cycle arrest, damage repair, and apoptosis (thus also establishing its importance in cancer development), numerous reports have demonstrated additional functions of p53 in various cells. In particular, p53 appears to
have important functions as it relates to neurodegeneration and synaptic plasticity. Objective: In this review, we will address p53 functions as it relates to various neurodegenerative diseases, mainly its implications in the development of HIV-associated neurocognitive disorders. Conclusion: p53 plays a pivotal role in the development of neurodegenerative diseases through its interaction with cellular factors, viral factors, and/or small RNAs that have the ability to promote the development of these diseases. Hence, inhibition of p53 may present an ideal target to restore neuronal functions. Copyright (C) 2011 selleck S. Karger AG, Basel”
“Vocal ford paralysis is a condition often seen in otolaryngologic adult and pediatric clinics. We report a case we believe to be the youngest child to undergo ansa cervicalis (ansa) to recurrent laryngeal nerve (RLN) reinnervation for unilateral vocal fold paralysis. We have included the preoperative and postoperative videostroboscopic
and acoustic findings. The acoustic data shows improvement and Cytoskeletal Signaling inhibitor is consistent with the patient’s improved voice quality. Most notably the patient’s voice quality is less raspy and his volume has improved while subjectively requiring less effort. (C) 2010 Elsevier Ireland Ltd. All rights reserved.”
“Context: Well-known causes of a cicatrizing ectropion are chemical/thermal injuries, dermatitis, cutaneous diseases, malignancies, and trauma. We add to this preceding list a systemic cause of a cicatrizing ectropion as a result of a rare side effect of 5-fluorouracil (5-FU), a common and frequently used chemotherapeutic agent.
Methods: A case report demonstrating the clinical presentation of a cicatricial ectropion caused by (5-FU) chemotherapy toxicity in a patient with dihydropyrimidine dehydrogenase deficiency. We also describe
the subsequent investigations and management of this case.
Results: click here A bilateral cicatrizing lower lid ectropion, bilateral upper lid shortening, cicatrizing and sclerosing facial skin changes occurred in an 80-year-old male, undergoing preoperative chemoradiotherapy, incorporating Capecitabine, an oral 5-FU prodrug for a locally advanced rectal carcinoma. Severe 5-FU toxicity ultimately proved fatal but in addition to typical 5-FU related adverse effects, the patient developed bilateral incomplete lid closure, secondary corneal exposure and keratopathy. Due to the patient’s extreme ill health, he was managed conservatively with a moist chamber.
Conclusion: 5-fluorouracil chemotherapy in patients with dihydropyrimidine dehydrogenase deficiency, can give rise to ocular and cutaneous toxicity.
