Nasal reshaping with hyaluronic acid: technique, risks, and benefits

Rhinoplasty is a common procedure performed by plastic surgeons. Nasal reshaping with hyaluronic acid (HA) is a fast and straightforward procedure that does not involve distancing recovery activities while providing results comparable to surgical rhinoplasty. Indications for nasal filling include patients who want to "test" the result of rhinoplasty, patients undergoing rhinoplasty who do not wish to further surgery to review a deformity, patients who are not candidates for surgery, and patients waiting for the appropriate time interval before undergoing a secondary rhinoplasty. The nose is the subunit of the face most at risk for fillings after glabella. As the number of patients submitted to fillings increases, so does the number of associated adverse effects

Bullous pyoderma gangrenosum and myelodysplastic syndrome

Pyoderma gangrenosum can present as a cutaneous manifestation of paraneoplastic syndromes. A case of bullous pyoderma gangrenosum associated with bicytopenia is described. During the complementary investigation, myelogram, bone marrow biopsy and karyotype were performed, and showed a pattern consistent with myelodysplastic syndrome. The patient was treated with dapsone with improvement. Pyoderma gangrenosum can be a manifestation of systemic diseases. The possibility of myelodysplastic syndrome should always be considered in patients with pyoderma gangrenosum associated with cytopenia. Pyoderma gangrenosum could indicate poorer prognosis in patients with systemic diseases.O pioderma gangrenoso pode apresentar-se como manifestação paraneoplásica. Relata-se um caso de pioderma gangrenoso, da variante bolhosa, acompanhado de bicitopenia, em que foi evidenciado, por meio de mielograma, biópsia de medula óssea e cariótipo, padrão compatível com síndrome mielodisplásica, subtipo citopenia refratária com displasia de multilinhagens. Foi tratado com dapsona, obtendo cicatrização das lesões. O pioderma gangrenoso pode associar-se a doenças sistêmicas, devendo a síndrome mielodisplásica ser considerada nos casos acompanhados de citopenias. Portanto, o pioderma gangrenoso pode ser um marcador cutâneo de doença sistêmica de prognóstico reservado.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de MedicinaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Anatomia PatológicaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de DermatologiaUNIFESP, EPM, Depto. de MedicinaUNIFESP, EPM, Depto. de Anatomia PatológicaUNIFESP, EPM, Depto. de DermatologiaSciEL
