ABSTRACT

Onychomycoses are fungal infections of the fingernails or toenails having a prevalence of 3% among adults and accounts for 50% of nail infections. It is caused by dermatophytes, non-dermatophyte filamentous fungi, and yeasts. Compressions and microtraumas significantly contribute to onychomycosis. Laser and photodynamic therapies are being proposed to treat onychomycosis. Laser light (1064 nm) was used to treat onychomycosis in 156 affected toenails. Patients were clinically followed up for 9 months after treatment. Microbiological detection of fungal presence in lesions was accomplished. A total of 116 samples allowed the isolation of at least a fungus. Most of nails were affected in more than two thirds surface (some of them in the full surface). In 85% of cases, after 18 months of the onset of treatment, culture turned negative. After 3 months months, only five patients were completely symptom-free with negative culture. In 25 patients, only after 6 months, the absence of symptoms was achieved and the cultures negativized; in 29 patients, 9 months were required. No noticeable adverse effects were reported. This study reinforces previous works suggesting the applicability of laser therapies to treat toenail onychomycosis.

ABSTRACT

Fundamento y objetivo: El hiperparatiroidismo por enfermedad renal crónica (ERC) puede alterar la composición y arquitectura ósea, y ocasionar fracturas. La densidad mineral ósea (DMO) determinada mediante densitometría (DEXA), empleada para predecir el riesgo de fractura1, estima la cantidad de calcio presente en el hueso. Sin embargo, desconocemos la relación entre DMO y la composición del hueso. Pacientes y método: Nuestro estudio se ha realizado en 2 grupos de pacientes con enfermedad renal que presentaban hiperparatiroidismo e intervenidos de paratiroidectomía, pacientes en hemodiálisis (grupo HD) y pacientes con trasplante renal (grupo TR). Se pretende: cuantificar y valorar las diferencias en la DMO entre estos dos grupos; cuantificar y definir diferencias en los parámetros de histomorfometrícos ósea entre estos 2 grupos y un grupo control; y definir si existe relación entre la DMO, elementos óseos y parámetros histomorfométricos.Resultados: El valor medio de la DMO en fémur fue superior en el grupo TR que en el grupo de HD. Del análisis de correlacion lineal realizado entre parámetros de DMO versus elementos en hueso e histomorfometría, considerando en conjunto TR y HD, únicamente observamos correlación entre DMO en fémur (gr/cm2) y calcio (r=0.435, p= 0.034, n=24).Conclusiones: Los pacientes con hiperparatiroidismo intervenido con TR tienen mejor DMO femoral que aquellos en HD. El volumen trabecular es inferior en TR, mientras que el volumen de fibrosis es superior en HD. Los elementos en hueso en TR y en HD se encuentran en proporción semejante, si bien el contenido de calcio tiende a ser superior en TR (AU)


Background and objectives: Hyperparathyroidism (HPT) in chronic kidney disease (CKD) may alter the composition and bone architecture, and cause fractures. The DEXA bone mineral density (BMD), used to predict fracture risk, measures the amount of calcium in bone. However, we do not know the relationship between BMD and bone composition. Patient and method: Our study, conducted in two groups of renal patients with HPT who underwent parathyroidectomy (PTX): patients on hemodialysis (HD group) and patients with renal transplant (RT group). The aims were to quantify and value the differences among groups and by gender on bone mineral density, quantify and define differences between these two groups and a control group regarding the elemental composition of bone marrow biopsy obtained and static parameters of bone histomorphometry, and define a possible relationship between bone mineral density and bone elements versus histomorphometric parameters. Results: The BMD mean in femur was higher in TR group than in HD group. Linear correlation analysis performed between parameters versus BMD and bone histomorphometry elements, considering both TR and HD, only correlation between femur BMD (gr/cm2) and calcium (r=0.435, p=0.034, n=24) was observed.Conclusion: Hyperparathyroidism patients undergoing renal transplant had better femoral BMD than those on hemodialysis; the trabecular volume was lower in kidney transplantation, while the volume of fibrosis was higher in hemodialysis patients; the elements in bone transplant and hemodialysis were in similar proportion, while the calcium content tended to be higher in renal transplant (AU)

ABSTRACT

Este artículo muestra la resolución de un proceso ulceroso de más de un año de evolución mediante cirugía. El conocimiento de la etiopatogenia del proceso, así como los factores que intervienen en su origen y evolución, son elementos que condicionan a la hora de la resolución y con ello a la opción del tratamiento de elección a realizar (AU)

ABSTRACT

Este artículo muestra la clasificación del pie diabético en seis grupos. Esta clasificación se lleva a cabo después de la exploración de los llamados factores de riesgo en este tipo de pacientes. Una vez conocemos a que grupo incluimos ese pie, determinamos nuestra actuación preventiva, con el fin de evitar la amputación parcial o total del mismo. Los factores de riesgo son los siguientes: neuropatía, angiopatía, morfología del pie, queratopatías y edema. Después de realizar la exploración y observar o no la presencia de los factores de riesgo clasificamos el pie en: Grupo 1: el pie diabético no tiene de ulceración; Grupo 2: los factores de riesgo están presentes; Grupo 3: existencia de ulceración; Grupo 4: la infección retrasa la curación y puede destruir los tejidos; Grupo 5: la necrosis es el resultado de la destrucción del tejido a partir de la infección y la isquemia; Grupo 6: aparición de osteitis extensa, la amputación es inevitable (AU)
