Resumen
La escisión de circuito grande de la zona de transformación (LLETZ) regenera parcialmente el volumen cervical, con la cantidad de tejido extirpado y la paridad que influye en la curación. La ecografía evalúa con precisión el volumen cervical después del procedimiento.
Área de la Ciencia:
- Ginecología
- Oncología quirúrgica
- Radiología
Sus antecedentes:
- El cribado del cáncer de cuello uterino a menudo implica la escisión de bucle grande de la zona de transformación (LLETZ).
- La comprensión de la regeneración cervical después de LLETZ es crucial para el manejo del paciente.
- Se necesitan métodos estandarizados de ecografía para evaluar las dimensiones cervicales.
Objetivo del estudio:
- Evaluar el impacto del LLETZ en las dimensiones cervicales.
- Identificar los factores que influyen en la regeneración cervical después del LLETZ.
- Verificar la concordancia entre las diferentes técnicas de ecografía para la evaluación del volumen cervical.
Principales métodos:
- Estudio observacional prospectivo (mayo 2022-abril 2023) en un hospital universitario.
- Mediciones ultrasónicas de longitud y volumen cervical antes de LLETZ y 3, 6 meses después del procedimiento.
- Regresión lineal generalizada para el análisis de factores; fórmula de cilindro frente al software VOCAL para la concordancia de volumen.
Principales resultados:
- La longitud cervical mostró una regeneración casi completa 6 meses después de LLETZ.
- El volumen cervical demostró una regeneración parcial a los 6 meses.
- El volumen de tejido extirpado y la paridad influyeron significativamente en la regeneración; las evaluaciones de volumen por ultrasonografía mostraron una alta concordancia.
Conclusiones:
- La regeneración cervical después de LLETZ es completa en longitud pero parcial en volumen.
- La cantidad de tejido extirpado durante LLETZ y la paridad del paciente son factores clave en la curación cervical.
- Los métodos ecográficos bidimensionales y tridimensionales proporcionan evaluaciones comparables del volumen cervical.

01:22Sutures of the Skull
13.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:16Vertebral Column: Regions and Curvature
8.6K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

01:30General Structure of a Vertebra
7.5K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:16Spinal Cord: Cross-sectional Anatomy
5.7K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...
