| Nodular fasciitis: USP6-associated neoplasia through multiple pathways | Author : Kazumi Fujioka | Abstract | Full Text | Abstract :Even though nodular fasciitis (NF) is benign and self-limited nature, the presentations of clinical, ultrasonographic, and pathological features have been described as mimicking sarcoma. Erickson-Johnson et al. suggested that ubiquitin-specific protease 6 (USP6) transcriptional upregulation may be the driving force behind the high proliferative activity and growth of NF. When the lesion showed the proliferative findings of the margin on both ultrasonography (US) and pathology, accompanied by clinically rapid growth, self-limited and/or regress course, NF could be strongly suggested as previously described. In this article, the author reviews the current knowledge of NF as USP6-associated neoplasia and also describes the therapeutic strategy in NF. In addition to the presentations of clinical, ulrtrasonographic, and pathological appearances of NF, the evaluation of percentage of USP6 break-apart FISH signals reflecting lifetime and mitotic counts in NF may be a potential procedure for accurate diagnosis in particularly young NF. It is putative that the inhibition of USP6-related genes might be the potential therapeutic strategies for the extremely rare malignant nodular fasciitis. |
| | Zingerone Alleviate Toxicity Induced by Cisplatin or Gamma Radiation in Rats by Modulating Pro-Inflammatory Mediators | Author : Gehan R. Abdel-Hamid | Abstract | Full Text | Abstract :Background: Zingerone is one of the active components of ginger that possesses multiple biological activities and anti-inflammatory properties against either radiation effect or cisplatin toxicity.
Purpose: to examine the protective effect of zingerone against gamma radiation (IR) or cisplatin-induced immunotoxicity.
Material and Methods: 48 rats were divided into six groups as follows: (group-1); normal control group received distilled water; (group-2); rats received Zingerone orally at a dose of 25 mg/kg b.wt. Once / day for 14 consecutive days (Zing.). (group-3); Rats were given a single injection of Cisplatin at a dose of 7.5 mg/kg b.wt. intraperitoneally (Cispl.). (group-4); Rats exposed to a single dose of 6 Gy whole-body gamma irradiation using 137Cesium source in a Gamma cell 40 (Rad.). (group-5); rats received same dose of Zingerone then they were exposed to gamma radiation as in group 4 (Zing+Rad.). (group-6); rats received Zingerone followed by single injection of Cisplatin at the dose of 7.5 mg/kg b.wt. Intraperitoneally (Zing+Cisp.).
Results: Exhibited a significant increase in expression of NF-?B, IL-10, caspase-3, and gene expression of TNF-a as well as oxidative stress biomarkers (MDA and NO) levels accompanied with a reduced level of SOD in either whole body-irradiated or cisplatin-received group. Conversely, pro-inflammatory cytokines levels were significantly decreased with an improvement of oxidative stress in groups that received zingerone.
Conclusion: It could be concluded that zingerone exerts its antioxidative activity and immunomodulatory effects through inhibition of pro-inflammatory mediators induced by whole body-gamma irradiation or cisplatin administration at two time interval early and late stage of radiation exposure (after 2 h and one week).Therefore, further studies are required to elucidate the molecular signaling pathway concerning zingerone. |
| | Karapandzic Flap for Functional & Cosmetic Reconstruction of Lower Lip Cancer with Review of Literature | Author : Sachin S Kadam | Abstract | Full Text | Abstract :The incidence and prevalence of lip and oral cavity cancer has increased over the last decade, worldwide and in India. It ranks at 1st position in males in india, all ages, in 2020. Lips are essential organ of the body which carries dynamic role in facial expression, speech, sensuality, deglutition. Resection of central, large, lower lip cancer creates a more than 2/3rd large defect. Covering of this defect with maintenance of oral competency is a difficult task for a treating surgeon. Number of techniques are described for covering of large lower lip defects. Out of these techniques, karapandzic flap is a successful, accepted, simple, easy to learn reconstructive procedure with good cosmetic results. It is a modification of Gillie’s fan flap and it involves unilateral or bilateral full-thickness circumoral advancement-rotation flaps. The feature which distinguishes it from other techniques is preservation of neuro-vascular integrity, symmetry and oral competency. We are reporting a case of an elderly gentleman with large, central, lower lip cancer who underwent oncological resection with reconstruction by karapandzic flap technique. |
