Korea
The eunuchs of Korea, called Naesi (내시, 內侍), were officials to the king and other royalty in traditional Korean society. The first recorded appearance of a Korean eunuch was in Goryeosa ("History of Goryeo"), a compilation about the Goryeo Dynasty period. In 1392, with the founding of the Joseon Dynasty, the Naesi system was revised, and the department was renamed the "Department of Naesi" (내시부, 內侍府).The Naesi system included two ranks, those of Sangseon (상선, 尙膳, "Chief of Naesi"), who held the official title of senior second rank, and Naegwan (내관, 內官, "Common official naesi"), both of which held rank as officers. 140 naesi in total served the palace in Joseon Dynasty period. They also took the exam on Confucianism every month. The naesi system was repealed in 1894 following Gabo reform. During the Yuan dynasty, eunuchs became a desirable commodity for tributes.Eunuchs were the only males outside the royal family allowed to stay inside the palace overnight. Court records going back to 1392 indicate that the average lifespan of eunuchs was 70.0 ± 1.76 years, which was 14.4–19.1 years longer than the lifespan of non-castrated men of similar socioeconomic status. Vietnam
The Vietnamese adopted the eunuch system and castration techniques from China. Records show that the Vietnamese performed castration in a painful procedure by removing the entire genitalia with both penis and testicles being cut off with a sharp knife or metal blade. The procedure was agonizing since the entire penis was cut off.
In these patients although the left ventricle is able to supply some blood flow to the rest of the body the overall left ventricular systemic output remains inadequate.In all of these cases blood is unable to be pumped to the rest of the body by the left ventricle. The neonate is reliant on blood flowing through an atrial septal defect to mix oxygenated and deoxygenated blood, and on a patent ductus arteriosus to allow blood to reach the aorta and the systemic circulation via the right ventricle. This is what defines HLHS as a "single ventricle" defect.Due to the underdevelopment of the left side of the heart in utero, the increased afterload causes hypertension of the left atrium, pulmonary edema, and therefore lung damage to the fetus before birth. Diagnosis
Hypoplastic left heart syndrome can be diagnosed prenatally or after birth via echocardiography. Typical findings include a small left ventricle and aorta, abnormalities of the mitral and aortic valves, retrograde flow in the transverse arch of the aorta, and left-to-right flow between the atria. It is often recognized during the second trimester of pregnancy, between 18 and 24 weeks gestation. Management
Medical
Without life-prolonging interventions, HLHS is fatal, but with intervention, an infant may survive. A cardiothoracic surgeon may perform a series of operations or a full heart transplant.
