概括
帕斯普拉纳玻璃切除术与子视网膜组织等离子体激活剂 (tPA) 注射有效地治疗来自视网膜动脉宏动脉瘤 (RAM) 破裂的子视网膜出血. 在两周内进行早期手术可以改善视力敏度,但RPE缩位置会影响结果.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜外科手术 视网膜外科手术
- 血管眼疾病 血管眼疾病
背景情况:
- 视网膜动脉大动脉瘤 (RAM) 破裂可能导致显著的脑下动脉出血,导致视力丧失.
- 亚管出血对视觉恢复构成挑战,因为它可能会损害光受体和视网膜色素上皮质 (RPE).
研究的目的:
- 评估帕斯普拉纳玻璃切除术 (PPV) 结合上腺复合组织等离子素激活剂 (tPA) 和用于RAM相关的上腺出血的气体吸管的长期功能和解剖学结果.
- 评估症状到手术间隔和手术后RPE缩对视觉结果的影响.
主要方法:
- 对18只眼睛进行PPV,上tPA注射和因RAM破裂而引起的下出血的气体吸管进行了回顾性分析.
- 在至少12个月的随访期间评估最佳校正的视敏度 (BCVA),中央黄斑厚度 (CMT) 和并发症.
- 分析症状到手术间隔和视觉结果之间的关系,以及RPE缩位置的影响.
主要成果:
- 在12个月内,BCVA从20/3300到20/140 (p < 0.001) 的平均值显著改善.
- 在14天内进行手术与更好的BCVA收益相关.
- 亚叶RPE缩 (38.9%) 与视觉结果的恶化有关 (p = 0.02);整体术后RPE缩发生在77.8%的患者中.
结论:
- 带有皮tPA和气体坦波纳的PPV对RAM相关的皮出血是有效的,可显著改善视力敏度.
- 及时的手术干预 (在两周内) 对于最佳的视力恢复至关重要.
- 手术后的RPE缩的位置是影响长期视觉结果的关键预后因素.

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System
2.1K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
