Paciente con amputación transfemoral derecha, clavo gamma y síndrome hemimotor derecho: valoración y manejo del proceso de protetización / Patient with a right transfemoral amputation, gamma nail, and right Hemi-motor syndrome: assessment and management of the prosthetic fitting

Introducción: la decisión de protetizar a un paciente amputado depende de: la etiología, nivel de amputación, uni o bilateralidad, comorbilidades, soporte sociofamiliar, capacidad funcional y motivación del paciente. Observación clínica: varón, 83 años, diabético, cardiopatía isquémica, accidente cerebrovascular con paresia braquial derecha residual en año 2000. Clavo gamma por fractura pertro-cantérea derecha en 2012 y amputación transfemoral derecha en 2018 de causa vascular. Se protetiza mediante encaje de contención isquiática CAT-CAM, sistema de suspensión tipo Kiss, rodilla de bloqueo a la extensión con adaptación del sistema de desbloqueo en porción antero-interna del encaje y pie Sach. Tras tratamiento fisioterápico, consigue deambulación autónoma con ayuda de un bastón y tercera persona por dificultad para agarre de MSD. Conclusión: los médicos rehabilitadores debemos apostar por dotar a nuestros pacientes de autonomía y funcionalidad, siempre que sea viable.

Introduction: prosthesis, an amputee patient, depends on etiology, level, uni or bilaterality, comorbidities, socio-family support, functional capacity, and motivation of the patient. Clinical observation: male, 83 years old, diabetic, ischemic heart disease, stroke with residual upper right limb (URL) paresis in 2000. Gamma nail due to the right trochanteric fracture in 2012, and right transfemoral amputation in 2018 of vascular cause. Prosthetic fitting CAD-CAM socket/interface, Kiss type suspension system, extension locking knee with an adaptation of the unlocking system in the antero-internal portion of the socket, and Sach foot. After physiotherapeutic treatment, he achieves independent walking with the help of 1 cane and third-person due to difficulty in the URL grip. Conclusion: rehabilitation doctors must bet on providing our patients with independency, and better function, whenever it is viable.

The role of socioeconomic status in the susceptibility to develop systemic lupus erythematosus in Mexican patients.

INTRODUCTION: Systemic lupus erythematosus (SLE) is an autoimmune inflammatory disorder for which Major Histocompatibility Complex (MHC) genes are well-identified as risk factors. SLE patients have different phenotypes or clinical presentations, which vary among Mexicans. This variation could be explained by ethnicity and admixture. Since socioeconomic status probably limits and change the patterns of migration, this factor could favor inbreeding and homogamy in some geographic areas. Consequently, it could alter or restrict the possibilities of admixture too. Therefore, the socioeconomic status may also have implications in the susceptibility and the clinical heterogeneity of SLE in Mexican patients. METHODS: One hundred twenty-three SLE patients and 234 healthy individuals with Mexican admixed ancestry were recruited. HLA alleles were analyzed using the HLA typing method based on Sequence-based typing (SBT). RESULTS: As expected, it was found an increased frequency of the HLA-DRB1*03:01 allele in all socioeconomic groups when compared with healthy individuals. The susceptibility allele found in the low-income SLE patients was HLA-DRB1*04:05 whereas, the susceptibility alleles for the high-income SLE patients were HLA-DRB1*07:01 (pC = 0.03, OR = 2.0) and HLA-DRB1*11:04 (pC = 0.0004, OR = 5.1). Additionally, the frequencies of two protective alleles HLA-DRB1*14:06 (pC = 0.01, OR = 0.28) and HLA-DRB1*16:02 (pC = 0.04, OR = 0.22) were found diminished. These findings correlate with the admixture differences between low-income and high-income SLE patients. The clinical manifestations showed a different distribution between both groups. Arthritis and neurological disorder were prevalent in low-income SLE patients, while the hematological disorder was prevalent in high-income SLE patients. CONCLUSIONS: These findings suggest that HLA class II DRB1 genes contribute to the susceptibility and protection to develop SLE differently depending on socioeconomic status. Due to this, the clinical manifestations vary among patients and it could be related to different admixture charge.Key Point• HLA class II DRB1 genes contribute to the susceptibility and protection to develop SLE differently depending on socioeconomic status.
