Scalp Infection Caused by Mycobacterium abscessus Manifested as Patchy Alopecia in an Immunocompetent Female.

Mycobacterium abscessus (M. abscessus) is a fast-growing, non-tuberculous mycobacterium (NTM) that can cause human infections varying from superficial infection to pulmonary or even systemic infections. The latter is more commonly appeared in immunocompromised patients. The skin infection caused by M. abscessus often appears after trauma or surgical procedure. It is often manifested by subcutaneous nodules, papules, erythema, tender erythematous or violaceous plaques, cellulitis, abscesses, ulcerations, and draining sinuses. Herein, we present a non-typical cutaneous manifestation of M. abscessus infection in a 46-year-old woman who presented with alopecia on the scalp with no itching or pain. The pathogen was isolated and identified as M. abscessus by morphology and DNA sequencing. To our best knowledge, there was no report that this organism could cause skin lesions mimicking patchy alopecia. After 3 months of antibacterial treatment, the cutaneous lesion disappeared, and new growth of hair occurred in this patient.

Management of skin damage of health workers' face: the role of plastic surgery in the time of Pandemic.

Background The Sars-Cov-2 virus is characterized by a being highly contagiousness, and this is the reason why massive use of personal protective equipment is required by medical and paramedical staff of the COVID-19 dedicated departments. The aim of this manuscript is to describe and share our experience in the prevention and treatment of the personal protective equipment related pressure sores and other skin alterations in the medical and paramedical staff. Materials and methods All healthcare workers with PPE-related skin damages were registered at time 0. Age, sex, profession, type of skin damage, diseases and possible drugs were registered. Results Two strategies were emplyed: the first strategy was to immediately treat the skin and the second one was to prevent pressure wounds formation both in already affected healthcare workers and the recurrence in healed staff. Three weeks after the two strategies were used, the incidence rate PPE-related skin damage was reduced in a statistically significant way. Conclusions Proper management helps in reducing the incidence of pressure ulcers related to  personal protective devices in CoVid-19 Units. Skin prevention and hydration, have been obtained achieved by using products applied at home, autonomously.

The Morphology and Bending Behavior of Regenerated Costal Cartilage with Kawanabe-Nagata Method in Rabbits - the Short Term Result of an Experimental Study.

BACKGROUND: The chest wall deformity is a well-known complication following costal cartilage harvest with the biomechanical factor considered to be a cause of this donor-site morbidity. Kawanabe-Nagata method is a widely-accepted approach to prevent the deformity. However, knowledge about the biomechanical properties of regenerated costal cartilage is limited, and the value of reimplantation of autologous costal cartilage blocks is not clear. METHODS: The fifth costal cartilage on both sides of six male, 8 weeks of age, New Zealand white rabbits were harvested with the perichondrium preserved intact in situ. The perichondrium was sutured to form a perichondrial pocket and part of the excised costal cartilage was cut into 0.5 mm cartilage blocks and returned to the perichondrial pocket of left side. The animals were sacrificed 16 weeks postoperatively and the regenerated and a piece native costal cartilage was harvested for morphological and three point bending test. RESULTS: There was no remarkable chest wall deformity in all animals, and there were no apparent differences in the appearance of the regenerated cartilage with and without reimplantation autologous cartilage blocks. The elastic modulus of native cartilage was significantly higher than the regenerated cartilage. The stiffness of regenerated cartilage without reimplantation was higher than that of with reimplantation, but this difference was not significant. CONCLUSIONS: The stiffness of regenerated cartilage was significantly lower than the native cartilage. Reimplantation of autologous cartilage blocks was not superior to that without reimplantation in regard to restoring the volume defect and strengthening the regenerated cartilage.

Fat graft for reducing pain in chronic wounds.

BACKGROUND: Chronic wounds are one of the most important challenge for regenerative surgery. Plastic surgeon can use fat graft to increase wound healing because its growth factors can enhance tissue regeneration. In a recent study, the authors evaluated a reduction of pain in a cohort of patients submitted to breast reconstruction with breast implant and lipofilling, putting into evidence that growth factors in fat graft can reduce post-surgical pain. The aim of this work is to evaluate ultra-filtered fat graft potential in reducing pain in chronic wounds. PATIENTS AND METHODS: Fifty new patients with chronic wounds of different etiology were recruited for this study and divided into two groups: A, treatment and B, control. Twenty-five patients per group. Negative pressure therapy dressing was applied after surgical debridement. Three days later patients in group A received ultrafiltered fat graft. Pain was evaluated with preoperative Visual Analogic Scale, repeated twice a day for 14 days and finally 21 days from procedures. RESULTS: In group A (treated patients), pain was lower. These data were confirmed even after 7 days. The overall statistical analysis of the average of all values (SD 1.72) confirmed that the differences were significant at the 95% with the Chi-square test and analysis of variance (P value < .05). CONCLUSIONS: The ultra-filtered fat graft placed on the wound bed and edges was effective in reducing pain in chronic wounds. The reduction of pain was statistically significant.

Taking care of healthcare workers during COVID-19 pandemic: does plastic surgery have a role?

BACKGROUND: The massive use of personal protective equipment is required by the medical and paramedical staff of the COVID-19 dedicated departments. This often causes painful pressure injuries. The aim of this study is to value the use of anesthetic cream and collagen veil masks for the treatment of pain. We also evaluated the possible psychological impact on healthcare workers involved in the emergency, which is currently a hot topic in the worldwide literature. MATERIALS AND METHODS: We applied lidocaine idrochloride 5% cream and a collagen veil mask respectively  before and after each work shift. We evaluated the improvement of pain symptoms through VAS assessments. We used a modified Maslach burnout inventory as well to evaluate the psychological impact of our treatments on  healthcare workers. RESULTS: A significant reduction of pain was detected within the first 3 days, but this was not significant over the long period (10 days). Otherwise, we saw a significant improvement of the psychological assessment (p<0,05). CONCLUSIONS: Parameters such as pain or psychological stress are not objective, but, anyway, our data show a  reduction of pain due to continuative PPE wearing and a significant improvement of psychological wellness of healthcare workers from two different countries, a finding which should not be undervalued by all the health caregivers not directly involved in COVID-19 pandemic.

[Mechanical study of polyurethane elastomer and Medpor as the material of artificial auricular scaffold].

OBJECTIVE: By comparing the mechanics of human auricular cartilage, polyurethane elastic material, and high density polyethylene material (Medpor), to produce theoretical proof on choosing optimal artificial auricular scaffold materials. METHODS: The experimental materials were divided into 3 groups with 6 samples in each: the auricular cartilage group (group A), the polyurethane elastic material group (group B), and the Medpor group (group C). With an Instron5967 mechanical testing machine, compression and tensile testing were performed to respectively measure values of compression parameters (including yield stress, yield load, elastic modulus, yield compressibility, compressibility within 2 MPa, and compression stress within 10% strain) and values of tensile parameters (including yield stress, yield load, elastic modulus, yield elongation, elongation within 2 MPa, tensile stress within 1% strain) for comparison. RESULTS: Compression testing: no obvious yield points were observed in the whole process in samples of group B, while obvious yield points were observed in samples of groups A and C. There was no significant difference between groups A and C with respect to yield stress and yield load ( P>0.05); while the yield compressibility in group C was significantly lower than that in group A ( P<0.05) and the elastic modulus in group C was significantly higher than that in group A ( P<0.05). There was a significant difference with respect to compressibility within 2 MPa of materials among the 3 groups ( P<0.05), the high, medium, and low values go to groups B, A, and C respectively. The compression stress within 10% strain in group C was significantly higher than that in groups A and B ( P<0.05), and there was no significant difference between that in groups A and B ( P>0.05). Tensile testing: the materials in group B had extremely high tensile strength. The yield stress in groups A and B was significantly higher than that in group C ( P<0.05), and the elastic modulus and tensile stress within 1% strain were significantly lower than those in group C ( P<0.05); but no significant difference was found between those in groups A and B ( P>0.05). There was no significant difference with respect to yield load among the 3 groups ( P>0.05); but there was significant difference with respect to yield elongation among the 3 groups ( P<0.05), and the high, medium, and low values go to groups B, A, and C respectively. The elongation within 2 MPa in group B was significantly higher than that in groups A and C ( P<0.05), and there was no significant difference between that in groups A and C ( P>0.05). CONCLUSION: Compared with the Medpor, the polyurethane elastic material is a more ideal artificial auricular scaffold material.

Necrosis of the Glabella After Injection With Hyaluronic Acid Into the Forehead.

Skin necrosis is a rare but severe potential complication after injection of hyaluronic acid (HA). Based on the understanding of the causes and mechanisms of this complication, many precautions have been proposed. Still, this adverse reaction happened from time to time. Here, the authors present a patient with glabellar skin necrosis following an injection into the forehead using HA filler. Although not uncommon, this patient might suggest an alternative cause or mechanism of tissue necrosis following HA injection besides intravascular injection or extravascular compression directly by HA filler. Further study is needed to examine other possible causes in order to eliminate this risk.

[Reconstruction of large vermilion defects with buccinator myomucosal flap].

OBJECTIVE: To investigate a novel method for the reconstruction of large vermilion defects. METHODS: Based on the size and shape of the defects, a buccinator myomucosal flap pedicled with the junction of buccinator and orbicularis oris in the oral commisure was designed and rotated to reconstruct the large vermilion defects. The upper bound of the flap is at least 1 cm away from the stensen's duct. The width is about 2.5-3.0 cm, and the length is as far as to arrive the raphe pterygomancibularis. The donate site is directly closed primarily. There is no need for secondary pedicle division. RESULTS: From July 2003 to April 2013, 14 cases with large vermilion defects was reconstructed with this method. No flap necrosis occurred with primary healing. 5 cases were followed up with an average follow up period of 1 year (0.5-3 years). The apprearance and function of the reconstructed vermilion were satisfactory without any apparent donor site defect. The patients were satisfied with both the functional and cosmetic results. CONCLUSION: The buccinator myomucosal flap is a simple and ideal method for reconstruction of large vermilion defects, especially for the defects closed to the commisure.
