The aim of this study was to quantitatively estimate the effect of hypertension upon the left ventricle, using the systolic time intervals. The subjects for this study consist of 72 hospitalized hypertensive patients including 38 males and 34 females. The measurements of the systolic time intervals were obtained from simultaneous high speed recording(100mm/sec) of an electrocardiographic lead best displaying the onset of left ventricular depolarization, a carotid pulse tracing, and a phonocardiogram best displaying the initial high frequency vibrations of the aortic valve closure sound. All data were corrected for heart rate and sex using the regression equations of Weissleretal. The results were follows: 1) As the diastolic blood pressure increased, shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. 2) As the electrocardiographic findings related to hypertension became severe shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. 3) As the hypertensive retinopathy became severe, shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. It was suggested that the measurement of the systolic time intervals are useful in assessing the effects of hypertension upon the left ventricular function and in detecting early recognition of cardiac dysfunction in hypertension, even though not necessarily associated with overt heart failure.

Noninvasive prenatal test (NIPT) is a novel screening method for the diagnosis of fetal chromosomal aneuploidies. NIPT is based on technology that detects cell-free fetal DNA in maternal plasma and analyzes it with massively parallel sequencing technology to determine whether the fetus is at risk of trisomy 21, trisomy 18, trisomy 13 or sex chromosome abnormalities (SCAs). NIPT has been reported to have sensitivity of 99% and a false positive rate of less than 1% for detecting trisomy 21 and trisomy 18. Although extension of the application of NIPT to other SCAs has been attempted, there are concerns in extending NIPT to SCAs because of maternal or fetal mosaicism, undetected maternal SCAs, and multiple pregnancies. Recently, we assessed a pregnancy with the rare Turner syndrome mosaicism 45, X/47, XXX, which was reported as 45, X with NIPT. We present the case here and briefly review the current literatures on NIPT in testing for fetal monosomy X. To the best of our knowledge, this is the first report of the 45, X/47, XXX mosaicism in Korea to be reported as 45, X by NIPT with whole genome sequencing. This case report will provide valuable information for counseling women who want to undergo NIPT.

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in women, which is characterized by the oligo/ anovulation, hyperandrogenism (HA) and polycystic ovarian morphology which are diagnostic criteria. PCOS has diverse clinical aspects in addition to those diagnostic criteria including increased risk for cardiovascular diseases, metabolic syndrome, dyslipidemia, type 2 diabetes and impaired fertility. Because of the heterogeneity of the disease, the pathogenesis of the disease has not been elucidated yet. Therefore, there is no cure for the endocrinopathy. HA and insulin resistance (IR) has been considered two major pillars of the pathogenesis of PCOS. Recent advances in animal studies revealed the critical role of neuroendocrine abnormalities in developing PCOS. Several pathways related to neuroendocrine origin have been investigated such as hypothalamus pituitary ovarian axis, hypothalamus pituitary adrenal axis and hypothalamus pituitary adipose axis. This review summarizes the current knowledge about the role of HA and IR in developing PCOS. In addition, we review the results of recent genome wide association studies for PCOS. This new perspective improves our understanding of the role of neuroendocrine origins in PCOS and suggest a novel potential therapeutic target for the treatment of PCOS.

In the past, irritant or radiation therapy have been used to treat discoid lupus erythematosus, therefore malignant and proriferative change in the lesion of discoid lupus erythematosus were not uncommon. In recent year, however, because the preferred treatment of discoid lups erythematosus consisted of steroids and antimalarials, the association with squamous cell carcinoma has been extremely rare. We present a case of giant squamous cell carcinoma arising in the discoid lupus erythematosus in 39 year-old women. She had had a 20 year history of facial discoid lupus erythematoseus. In September of 1976, a thumb tip-sized tumor mass found on the right cheek and the maas grew into the adult palm size rapidly. The tumor show ulceration, serosanguinous discharge, easy bleeding, and foul oder. Histopathologically, the specimen obtained from plaques of the left cheek showed hyperkeratosis with plugging, atrophy of the stratum malpighii, a patchy, chiefly lymphoid cell infiltrate with a tendency to arrangement about the cutaneous appendages, hydropic degeneration of the basal cells, edema and vasodilatation in the dermis. The specimen obtained from tumor mass of the right cheek showed many nests consisted of well differentiated squamous cells, keratin pearls.

Discrete subaortic stenos is one of the subtype of congenital left ventricular outflow obstruction and frequently associated with other defect such as ventricular septal defect, coarctation of the aorta, inturrupted aortic arch, double-chambered right ventricle and atrioventricular canal. It is progressive disease from the neonatal period and can be a cause of secondary endocarditis or aortic regurgitation. The authors have experienced a case of discrete subaortic stenosis without other associated lesions in 8 years old male patient who has complained chest discomfort. The diagnosis was established by the findings of echocardiography and cardiac catheterization. We report this case with a brief review of related literatures.
