Case Report Lingual Abscess in a Psychiatric Patient: A Case Report

We present a 46-year-old psychiatric patient presenting with a lingual abscess. This paper covers the epidemiology, clinical features, diagnosis, and differential diagnosis with a view to assisting emergency physicians in the timely recognition and management of this rare but potentially life-threatening condition

A Rare Cause of Peripheral Facial Nerve Palsy: Chondromyxoid Fibroma of the Temporal Bone

Purpose:To report a rather rare entity of facial palsy due to chondromyxoid fibroma. The authors present a case along with clinico-pathological features, management, treatment options and follow-up.Methods:The authors present a case of a 29-year-old male who suffered from right facial weakness and numbness for a period of 6-months. imaging studies demonstrated a soft, locally invasive tumor, located mainly in the right temporal bone and extended extracranially.Results:A surgical procedure of local excision followed by cross-facial nerve grafting was performed.Conclusions:Diagnosis should be based on combination of histo-pathologic and radiographic findings, because of its histological similarities to chondrosarcoma. © 2022 Lippincott Williams and Wilkins.

Inhibition of molar eruption and root elongation in MT1-MMP-deficient mice

To study whether eruption of teeth and root growth require remodeling of collagen in the peridental tissues, we studied molar development in mice deficient in MT1-MMP, an enzyme essential for remodeling of soft tissue-hard tissue interfaces. The lower jaws of deficient mice and their wildtype littermates were subjected to stereologic analysis. It was shown that in deficient animals, eruption and root elongation were severely inhibited, signifying a role of the enzyme in these developmental processes

On the role of MT1-MMP, a matrix metalloproteinase essential to periodontal collagen remodeling, in murine molar eruption and root growth

Although the connective tissues of the periodontium are subject to a high turnover rate, no conclusive evidence has yet emerged that periodontal collagen turnover is essential for the eruption of teeth or for root elongation. These processes were studied in mice deficient in MT1-MMP, a membrane type matrix metalloproteinase essential for remodeling of soft tissue-hard tissue interfaces. Mandibular first molars of deficient mice and their wild-type littermates were subjected to stereological analysis in order to assess root length, eruption and the volume density of phagocytosed collagen in periodontal ligament fibroblasts. The data showed that both eruption and root elongation were severely inhibited in animals lacking the enzyme. We also found, in periodontal ligament fibroblasts from MT1-MMP-deficient mice, a massive age-related accumulation (up to 60-fold over controls) of collagen fibril-containing phagosomes. Phagolysosomes, which represent the next downstream step in collagen fibril degradation by the lysosomal pathway, did not accumulate. These observations indicate that MT1-MMP plays a central role in periodontal remodeling. The stunted root growth and the failure to erupt indicate the important role of the enzyme in tooth developmen
