Fat grafting associated with negative pressure wound therapy

Abstract Purpose: To describe a case report of FG associated with NPWT in the treatment of complex wound on the distal third of the lower limb with bone exposure. Case Report: A 59-year-old patient with chronic left tibial osteomyelitis since childhood underwent extensive debridement of the distal tibial diaphysis (40% of bone thickness per 10 cm extension) and placement of bioactive glass S53P4. Distal necrosis occurred in the fasciocutaneous flap used as the primary bone coverage. After flap debridement, the case was resolved with FG, directly on the exposed bone and biomaterial, associated with NPWT. Three weeks after the first FG session over bony tissue, 100% granulation was achieved with NPWT. The closure was completed with thin laminated skin graft over the granulated wound area. Discussion: The association of FG and NPWT is not known in the clinical practice. Except for the only one experimental study described by Kao et al.4, the theme was not addressed in the medical literature before. In this clinical case, the result obtained regarding the granulation tissue formation drew attention and prevented the use of more complex flaps such as the microsurgical ones. Accelerated granulation tissue formation was observed, filling an extensive and deep bone defect, even with infected bone and biomaterial. Low morbidity and no complications were observed with the use of FG associated with NPWT. When the grafted fat was compacted with the NPWT, it seemed to behave as a true autologous biological matrix with large amount of cells. To date, scientific studies on fat grafting have focused on the cellular aspect (adipocytes and mesenchymal cells), growth factors and fat differentiation in different tissues. The property of aspirated adipose tissue as a biological matrix seemed to be revealed by the application of NPWT in association with FG. This new roll for the aspirated fat tissue may represent a new research field in plastic surgery.

Caracterización y seguimiento durante seis meses de una cohorte de recién nacidos con sífilis congénita / Characterization and six-month follow-up on a cohort of newborns with congenital syphilis

Introducción. La sífilis congénita es una enfermedad prevenible cuya incidencia en Colombia ha aumentado, alcanzando la cifra de 3,28 casos por 1.000 nacidos vivos en el 2011. Objetivo. Caracterizar a los recién nacidos con sífilis congénita y describir su diagnóstico y tratamiento durante el seguimiento de seis meses. Materiales y métodos. En el periodo comprendido entre agosto de 2011 y febrero de 2012 en el Hospital La Victoria, sede Instituto Materno Infantil, se identificaron y trataron los recién nacidos con sífilis congénita, y se hizo seguimiento clínico y de laboratorio hasta la curación de la enfermedad. Las variables analizadas incluyeron las características clínicas y de laboratorio. Resultados. En este periodo se diagnosticaron 29 pacientes que cumplían con los criterios de caso de sífilis congénita, cuya frecuencia en la institución era de un caso por cada 69 nacimientos. Hubo un mortinato y una muerte neonatal, cuatro recién nacidos fueron prematuros y cinco presentaron restricción en el crecimiento. De los 28 recién nacidos vivos, 15 fueron asintomáticos. Se presentaron dos casos con neurosífilis, es decir, 15 % de los sintomáticos. Se hizo seguimiento a 18 de los 27 niños (66,6 %), incluidos la mayoría de los sintomáticos y los dos casos con neurosífilis; la disminución esperada de los títulos en la prueba del Venereal Disease Research Laboratory , VDRL, se presentó en todos los pacientes, y no hubo secuelas clínicas, con lo que se cumplieron los criterios de curación. Conclusiones. Se evidenció una gran incidencia de la enfermedad, fallas en su prevención, una variada expresión en su presentación y la efectividad del tratamiento en el periodo neonatal.

Introduction: Congenital syphilis is a preventable disease. However, the incidence in Colombia has increased and reached the figure of 3.28 cases per 1,000 live births in 2011. Objective: To characterize newborns with congenital syphilis and describe follow-up over 6 months following their diagnosis and treatment. Materials and methods: Between August, 2011, and February, 2012, in Hospital La Victoria, sede Instituto Materno Infantil , newborns with congenital syphilis were identified and treated. Clinical and laboratory follow-up was carried out for six months until it was determined that the disease was cured. The analyzed variables included patients´ clinical and laboratory characteristics. Results: In this period, we identified 29 cases that met the criteria of congenital syphilis, with a frequency in the institution of one case per 69 births. There was one stillbirth and one neonatal death, four were premature, and five had growth restriction. Of the 28 live births, 15 were asymptomatic. There were two cases with neurosyphilis, representing 15% of symptomatic newborns. Follow-up was done on 18 out of 27 children (66.6%), including most symptomatic cases and the two cases of neurosyphilis . All cases showed the expected decrease in VDRL titers without clinical sequelae, meeting the criteria of being cured. Conclusions: A high incidence of the disease, failure to prevent it, varied expression in its presentation, and the effectiveness of treatment in the neonatal period were evidenced in this study.
