Ovarian hyperstimulation syndrome (OHSS) is a potentially severe complication following ovarian stimulation. It has a clinical spectrum ranging from a mild form, which accounts for most cases, to moderate and severe forms that occur rarely but deserve special attention since they are life threatening [1]. Clinical manifestations of OHSS can be classified into (1) mild, with abdominal distension...

We examined whether hemorheology and platelet function are affected in essential hypertensives (EHTs) of the World Health Organization stage I when complicated with metabolic syndrome (Mets). In 156 untreated EHTs, blood viscosity and platelet surface markers were determined. Blood viscosity was significantly elevated in 54 subjects with Mets compared with 102 subjects without Mets. Hematocrit ...

The cause of toxemia of pregnancy is still unclear, and therefore this condition is only treated symptomatically. Edema, hypertension, and proteinuria are the three key elements of this condition, but drug treatment generally targets only hypertension. Although hydralazine hydrochloride and methyldopa have long been used as antihypertensive therapies, newer drugs such as calcium antagonists hav...

Ovarian hyperstimulation syndrome (OHSS) is a lifethreatening iatrogenic complication of in vitro fertilization (IVF). One of the characteristic features of OHSS is increased vascular permeability due to the overproduction of vasoactive mediators from hyperstimulated and enlarged ovaries. Such altered permeability leads to fluid shifts from intravascular to interstitial or third-space compartme...

Systemic capillary leak syndrome (SCLS), also called Clarkson's disease is rare and life-threatening disorder of unknown etiology, which is a characteristic triad of hypovolemic shock, hemoconcentration, and hypoalbuminemia. Unexplained capillary leakage from the intravascular to the interstitial space, which has been estimated up to 70% of the intravascular volume, is the proposed mechanism. B...

A 57-year-old woman was admitted to our hospital because of frequent bloody diarrhea, vomiting, and abdominal cramps. While the patient was diagnosed with norovirus gastroenteritis based on the presence by chance of positive norovirus antigen in the stool samples, endoscopic as well as pathological examinations demonstrated left-sided ischemic colitis. The patient soon recovered solely by suppo...
