1.A Case of Short Stature with 46, XXp+(Xqter-->Xp22::Xp22-->Xqter).
Journal of Korean Society of Pediatric Endocrinology 1997;2(1):133-138
We experienced a case of Turner variant in 17 year old girl. She showed normal appearance except short stature. The patient was born at term with a birth weight of 2200g and her height was below the 3 percentile at admission. Thelarche appeared at the age of 13 years. FSH and LH levels were elevated, estradiol was within normal range, but progesterone level was decreased, bone age was 14 to 15 year old, and the small sized uterus was detected by abdominal ultrasonogram. Karyotype analysis revealed 46,XXp+(Xqter-->Xp22::Xp22-->Xqter). Her height didn't grow properly despite serial growth hormone therapy, because her epiphyseal growth plate was nearly closed.

This study was designed to validate the usefulness of the near point of convergence(NPC)test in determination of dominant & non-domnant eyes in intermittent exotropia patients. We performed NPC test in 36 intermittent exotrpic patients, and then, determined the non-dominant eye which deviated outward beyond the NPC. The dominant eyes determined by the NPC were compared to those that were determined by amblyopia, sensory fusion and photophobia. Best corrected visual acuity was used to divide patients into two groups : 26 patients without amblyopia, and 10 with amblyopia. Among the amblyopia group, if the eyes with better visual acuity were taken as dominant eyes, then eight(80%)cases were identical with the NPC test and two(20%)cases were different. Ten patients had sensory anomaly, and among then, nine(90%)cases were identical with the NPC test and one(10%)case was different. Twenty six(64%)patients had photophobia in one eye and all(100%)cases were identical with the NPC test. In intermittent exotropia, determination of dominant eye by the NPC test showed high coincidence with other tests. Therefore, we suggest that the NPC test is an easy and accurate method in determining either the dominant or non-dominant eye for surgery.

BACKGROUND: Doppler echocardiography is a non-invasive technique that has been used to evaluate LV diastolic dysfunction. Impaired left ventricular diastolic filling is known to occur in patients with coronary artery disease. Compared with those in normal subjects, Doppler-derived transmitral blood flow velocities have been reported to be reduced during early diastolic filling and to be compensatory elevated subsequent to atrial systole in patinets with coronary artery disease. But stiffness of myocardium normalize the E/A ratio, and normal E/A ratio may reveal increased ventricular filling pressure. We tried to investigate left ventricular filling parameters by Doppler echocardiography in patients with early myocardial infarction, and to compare left ventricular diastolic function regarding infarct location on EKG, one or multivessel disease on coronary angiography, and treatment modality. METHODS: From September 1993 to August 1995, Pulsed wave Doppler echocardiography was performed in patients with early acute myocardial infarction(N=95) and control group(N=20) within 5 days after admission, and parameters of diastolic function was evaluated. RESULTS: Echocardiographic data showed significant differences in mean ejection fraction, mean left ventricular mass, and mean left ventricular mass index between two groups. There was no significant difference in E/A ratio, deceleration time, and isovolumetric relaxation time between two groups. Neither, there was significant difference in each diastolic parameter for infarct related wall on EKG. And there was no significant difference in deceleration time for one or multi vessel disease on coronary angiography, treatment modality(conservative treatment, thrombolytic therapy, or primary PTCA). CONCLUSION: In patients with early acute myocardial infarction, left ventricular diastolic dysfunction was absent. And there was no significant correlation between the presence of diastolic dysfunction and the location of infarct related wall on EKG, or one or multi vessel disease, or treatment modality.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

BACKGROUND: Left ventricular hypertrophy is a major cardiovascular risk factor for sudden death, acute myocardial infarction and congestive heart failure. The left ventricle is generally thought to adapt to sustained arterial hypertension with increased total peripheral resistance by developing concentric hypertrophy. In recent years, the echocardiogrphy has been developed as a noninvasive method for evaluation of left ventricular geometry and left ventricular mass. However, left ventricular adaptation to hypertension has been shown to be more complex than expected. In fact, many patients with mild to moderate hypertension exhibit normal left ventricular mass and wall thickness, other hypertensive patients have eccentric ventricular hypertrophy that is not related to systolic dysfunction, but rather to increased cardiac output and preload and in some hypertensive patients absolute and relative wall thickness is increased with normal ventricular mass(concentric remodeling). There are differences in the hemodynamics, systolic function and diastolic function in each group. METHODS: From september 1992 to August 1994, in 144 patients with untreated essential hypertension and 50 age and gender matched normal adults studied by two-dimensional, M-mode and Doppler echocardiography. In the present study we used echocardiographically derived left ventricular mass and relative wall thickness to assess the patterns of ventricular geometric adaptation to systemic hypertension and their relations to systemic hemodynamics, left ventricular load and contractile performance. RESULTS: Hypertensive group was 144 cases(M:F=68:76), the mean age 56+/-13years. Normotensive group was 50 cases(M:F=22:28), the mean age 52+/-9years. Among hypertensive patients, left ventricular mass index and relative wall thickness were normal in 42 cases(29%), 24 cases(17%) had increased relative wall thickness with normal ventricular mass(concentric remodelin),48 cases(33%) had both increased relative wall thickness and ventricular mass(concentric hypertrophy), 30 cases(21%) had increased left ventricular mass with normal relative wall thickness(eccentric hypertrophy). Concentric hypertrophy and normal left ventricle group are more common in untreated hypertensive patients in Korea. Systemic hemodynamics showed tendency to paralleled ventricular geomety. In groups with concentric remodeling and hypertrophy, perpheral resistance was increased. Cardiac index was midly increased in eccentric hypertrophy. Diastolic dysfunction was prominent tn concentric hypertrophy. CONCLUSION: Each patterns of left ventricular geometry had different systemic hemodynamics, ventricular pressure overload and ventricular volume overload. Therefore, appropriate selection of antihypertensive agent for the patients with each patterns of hypertrophy reduce the left ventricular hypertrophy and may improve the prognosis.
