Useful results within mouth reconstruction using myomucosal buccinator flap.
A large portion of this increase in growth can be attributed to the growth in number of rhytidectomies performed. DISCUSSION This study evaluated the impact of social media on the volume of aesthetic cases performed through an established chief resident clinic and its utility in patient recruitment. Chief residents had an increase in the number of aesthetic surgery cases they performed after their clinic was featured on an online social media physician review website. This further reinforces the impact social media and an online presence have on plastic surgery training.BACKGROUND Histological differentiation between hypertrophic scars (HSs) and keloids has been considered difficult. In this study, we analyzed differences in the 3-dimensional tissue architecture between HSs and keloids using focused ion beam/scanning electron microscopy (FIB/SEM). METHODS Five specimens each of normal skin, normotrophic scars (NSs), HSs, and keloids were investigated. Three sites in each specimen were observed by FIB/SEM tomography, resulting in an observation of 15 sites per tissue type. We identified fibroblasts and macrophages and assessed the contact ratio and the mode of intercellular contact (planar contact or point contact). The significance of differences among the 4 tissue types was determined by Fisher exact test. RESULTS In normal skin, contact between fibroblasts and macrophages was observed at all 15 sites, and the mode of contact was always planar. There was contact at 87% of the NS sites (planar point = 80% 7%). In HSs, contact was seen at 80% of the sites (planar point = 20% 60%). In keloids, contact was found at only 15% of the sites (planar point = 7.5% 7.5%). The intercellular contact ratio showed no significant differences among normal skin, NSs, and HSs; however, a significant difference was noted between these tissues and keloids. The intercellular contact mode also showed no significant difference between normal skin and NSs, but a significant difference between these tissues and HSs. CONCLUSIONS These histopathologic findings suggest that FIB/SEM tomography is useful for distinguishing between HSs and keloids and can provide important knowledge for understanding the pathogenesis of keloids.INTRODUCTION Expanding surgical capacity is very difficult in resource-constrained countries. Financial input and additional physical operating room space are needed. The surgical patient volume exists, but the lack of operating room time causes postponement of cases. Hand surgery is particularly important as it improves patient function and allows for a timely return to the workforce after injury. Some hand surgery cases may be performed under local anesthesia with a very basic instrument set in a procedure room. This arrangement eliminates the need and financial burden of an equipped operating room and the need for an anesthesiologist. We hypothesized that performing hand surgery in a simple procedure room by a surgeon with knowledge of adequate local anesthesia could increase hand surgery capacity significantly in a low-income country. selleck inhibitor METHODS This technique has been instituted at Komfo Anokye Teaching Hospital in Kumasi, Ghana, with the use of a single procedure room that was previously used for storage. the main operating rooms. Although the case volume has increased surgical capacity significantly, costs to the hospital and patient have decreased. The hospital is reimbursed in a timely fashion for the procedures directly by the patient using this technique. The creation of a single procedure room for wide-awake local anesthesia no tourniquet hand surgery has helped address the issues of inadequate operating room space, time, and expense in resource-constrained Ghana.Melanocytic tumors with inactivation of protein kinase A regulatory subunit-α (PRKAR1A) have large oval nuclei and intense pigmentation. Historically, these tumors have been categorized under various names, including epithelioid blue nevus, pigmented epithelioid melanocytoma (PEM) and animal-type melanoma. Although a subset of PEM harbor BRAF activating mutations and biallelic inactivation of PRKAR1A, there are only a few reports of melanomas, or of tumors with genomic alterations beyond those of PEMs. Herein, we describe the clinicopathologic and genetic features of 8 melanomas and tumors that lack PRKAR1α expression by immunohistochemistry but do not fit with conventional PRKAR1A-inactivated melanocytomas. These tumors tended to affect younger patients than conventional melanomas (median age=38 y) and presented as dark brown/black papules and nodules. Histopathologically, they demonstrated nodularity, sometimes in a background of conventional melanoma, and large vesicular nuclei with prominent nucleoli. Witf PRKAR1A-inactivated melanomas, discuss the differential diagnosis of heavily pigmented epithelioid melanocytic neoplasms, and propose a new nomenclature for such tumors.In patients with multiple myeloma, plasmablastic transformation in the bone marrow is rare and associated with poor outcomes. The significance of discordant extramedullary plasmablastic transformation in patients with small, mature clonal plasma cells in the bone marrow has not been well studied. Here, we report the clinicopathologic, cytogenetic, and molecular features of 10 such patients (male/female 6/4, median age 65 y, range 48 to 76 y) with an established diagnosis of multiple myeloma in the bone marrow composed of small, mature plasma cells in parallel with a concurrent or subsequent extramedullary plasmablastic transformation. Eight patients with available survival data showed an overall aggressive clinical course with a median survival of 4.5 months after the diagnosis of extramedullary plasmablastic transformation, despite aggressive treatment and even in patients with low-level bone marrow involvement. Pathologically, the extramedullary plasmablastic myeloma were clonally related to the corresponding bone marrow plasma cells, showed high levels of CMYC and/or P53 expression with a high Ki-67 proliferation index by immunohistochemistry and harbored more complex genomic aberrations including frequent mutations in the RAS pathway and MYC rearrangements compared with their bone marrow counterparts. In summary, although genetic and immunohistochemical studies were not uniformly performed on all cases due to the retrospective nature of this study, our data suggest that discordant extramedullary plasmablastic transformation of multiple myeloma has an aggressive clinical course and is characterized by frequent mutations in the RAS pathway and more complex genomic abnormalities.
