Introduction: Trichilemmal cysts (TCs) are common skin lesions that occur in hairy areas. A TC involving a fingertip has not been previously described in the literature. We herein report a case of a TC occupying a fingertip region.Case presentation: A 43-year-old woman presented with a 1:5 Â 1:5 cm nodular lesion on the third fingertip. The lesion was completely excised, and histopathological examination revealed a TC.Conclusion: TCs may involve atypical locations, such as fingertips, where there are no hair follicles. After surgical excision, a careful histopathological examination should be performed to differentiate TCs from proliferating pilar tumors.
Soft-tissue defects of the pretibial region constitute a major reconstructive challenge because of the insufficiency of the local tissues. In such cases, a long cross-leg flap may be an alternative option. This study presents a case with an atonic wound in the pretibial region caused by a previous traffic accident, which had received cross-leg flap repair following the excision.
The deltoid free flap is a thin, reliable flap that is easily dissected from the posterolateral arm. It has large-caliber vessels and is capable of sensory reinnervation to portions of the flap above the deltoid/triceps groove through the lateral brachial cutaneous nerve. There is little sensory return to the large vascular territory, which can be extended inferiorly below the deltoid triceps groove. The donor site can be closed primarily or skin grafted and when large may be objectionable to some patients. The flap is an excellent choice for extremity soft-tissue reconstruction on the plantar or palmar surfaces. Because of its excellent color-matching and texture-matching characteristics, it has recently been widely used for the reconstruction of soft-tissue defects during oral and maxillofacial surgery.
Management of condylar fractures has been the subject of much disagreement and debate. There is no general consensus for definitive treatment. Although there is a growing tendency for open reduction and internal fixation technique, risks and morbidity of the surgical procedure are still a point of concern for maxillofacial surgeons. To reduce potential complications and improve surgical exposure, the transmasseteric anteroparotid approach was introduced. Since 2008, we have operated on 6 patients (7 fractures) using this approach. The technique is easy to learn, provides adequate surgical exposure for open reduction internal fixation, and has few complication rates.
Background. Epigallocatechin gallate (EGCG), a green tea polyphenol, has potent antioxidant properties. Objectives. The purpose of the present study was to examine the possible preventative effects of EGCG against internal organ injury due to large-surface skin burns in a rat model. Material and Methods. The study design involved three groups of rats: a sham group and two groups with 25-30% full-thickness burns: (a) the sham group without burns or treatment (n = 18); (b) the control burn group (burns + sterile saline, n = 18); and (c) the burn treatment group (burns + treatment with EGCG, n = 18). EGCG was administered intraperitoneally immediately after the thermal injury, and daily in 100 μmol/kg doses. Kidney and lung tissue samples were taken to determine the levels of malondialdehyde (MDA), superoxide dismutase (SOD), tumor necrosis factor-α (TNF-α), and glutathione peroxidase (GPX) after the first, third and seventh post-burn days. Results. In the EGCG-treated burn group, SOD and GPX activity were significantly higher than in the burn control group. Additionally, MDA and TNF-α levels were significantly lower in the EGCG-treated burn group. Conclusions. Based on this study, it might be anticipated that EGCG treatment may be beneficial in burn injury cases (Adv Clin Exp Med 2015, 24, 3, 409-417).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
