Nasal dermoid cysts are rare congenital anomalies that affect one in 20,000 to one in 40,000 individuals. Herein, we report a case of an initially misdiagnosed nasal dermoid cyst with intracranial extension. Among nasal dermoids, the lesion of the nasal tip is considered uncommon. Therefore, this should always be considered as a differential diagnosis of midline nasal masses, and a proper diagnostic approach should be taken.
Background Various types of external breast tissue expanders have been found to be effective for aesthetic breast augmentation. However, their use has been limited when compared with implant-based breast augmentation due to the burdensome nature of their application. This article reports the possibility that external breast tissue expanders may be applied safely and effectively with higher pressure and shorter application time.Methods The participants comprised patients who desired breast augmentation using the EVERA-RAPHA device between January 2020 and March 2020. A double-blinded prospective study was conducted on two groups of eight patients each, with either 60 mmHg or 100 mmHg of pressure applied. Standardized photographs were taken and blinded measurements of volume and circumference were made. The Mann-Whitney and paired t-tests were conducted.Results Sixteen patients were evaluated after 1 month of treatment. The women in groups 1 and 2 (60 mmHg and 100 mmHg, respectively) used EVERA-RAPHA for 15.400± 0.704 and 15.300±0.477 minutes per day, respectively. The mean volume increases in groups 1 and 2 were 39.000±42.526 cc and 27.700±20.260 cc, respectively. No patients dropped out of the study. All patients reported that the device was tolerable. Mild bruising was found in 62.5% of the patients in group 2.Conclusions Breast augmentation using external tissue expanders can be a safe, effective, and practical option. Pressures of 60 mmHg or 100 mmHg can be safely applied for a shorter duration. Larger studies are needed to further confirm our findings.
Radiation ulcers can occur as a complication following exposure to ionizing radiation. Advances in medical technology, followed by the wider range of radiation application in recent decades has steadily increased the incidence of radiation ulcers. Radiation causes hypoxia, hypovascularity, and hypocellularity in tissues. Moreover, the surrounding skin adjacent to the radiation ulcer lacks follicular stem cells and is more prone to chronic, non-healing wounds. While no guidelines have been established regarding optimal treatment, management facilitating angiogenesis and migration of fibrogenic cells can be a recommended option, considering the etiology of ulcers induced by radiation exposure. Herein, we present a patient exposed to prolonged radiation during a fluoroscopic intervention procedure, who had developed a vast radiation ulcer at his coccyx, and was completely treated with injectable acellular dermal matrix combined with 14 weeks of negative pressure wound therapy.
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.
