BACKGROUND Autologous fat injection is getting popular in cosmetic procedures, however, still has a risk of fat embolism. Herein, we report the first case of segmental ischaemic infarction of the iris, which occurred after autologous fat injection into the lower eyelid. CASE PRESENTATION A 28-year-old Korean woman complained of the discolouration of the iris after the fat injection. Slit-lamp...

BACKGROUND Acute renal infarction is an uncommon condition resulting from an obstruction or a decrease in renal arterial blood flow. Isolated spontaneous renal artery intramural hematoma is a rare cause of renal infarction. CASE REPORT A 46-year-old healthy man presented to our emergency room because of sudden onset of severe right flank pain. An enhanced abdominal computed tomography scan sh...

Utilizing the microsurgical method of transplantation in the rat, the role of the kidney in an experimental renal hypertension due to segmental renal infarction was studied. When the infarcted kidney was transplanted into the bilaterally nephrectomized recipient, hypertension developed so long as the donor kidney was transplanted within 2 weeks after infarction. With transplantation of the norm...

Left ventricular asynergy in myocardial infarction was assessed quantitatively by computer analysis of the cross sectional echocardiogram. Short axis cross sectional images of the left ventricle at the levels of the mitral valve, papillary muscle, and apex were recorded by a phased array sector scanner in 30 patients with healed myocardial infarction and 15 normal controls. Endocardial and epic...

OBJECTIVE Renal infarction is rare and has variable clinical presentations causing diagnostic difficulties. Although most renal infarctions are caused by an obvious thromboembolic factor some are only explained by hereditary or acquired thrombophilia. The authors present a case of segmental renal infarction associated with factor V Leiden. METHODS/ RESULTS: A 48-year-old man presented with righ...

According to the wide application of segmental lining in mechanized tunneling, recognizing the behavior of segmental lining joints is important in tunnels designing. In the structural analysis of the tunnel segmental lining, segmental joints can be considered as elastic joints, and their stiffness characteristics are affected by the rotational, shear, and axial stiffness. The purpose of this wo...
