It has been known that head posture may influence directly and/or indirectly the growth and development of craniofacial morphology and can also be influenced by the funtional demand of physiologic activity. It was reported that facial morphology has close relationships with hyoid bone position and head posture. In many previous studies, Natural Head Posture(NHP) was guided, and also it was shown that NHP has high degree of reproducibility. Otherwise, There was few study about the relationship of head posture, with routine cephalometric film which is used for clinical orthodontic purpose. In this study, according to the Wits and ANB of initial cephalometric film which was taken with vertical pendulum as representative of true vertical reference line. We classified the subjects which is comprised of 60 adult female patients into Class 1, II, III (Cl I, II, III)and we tried to find out the correlation of head posture and hyoid bone position according to the classification of malocclusion. As a result of our research, we found the followigs. 1. In comparison of vertical position of hyoid bone relative to the cranial base. the position of hyoid bone of Cl III was lower than that of Cl II. 2. In comparison of anteriorpostes or position of hyoid bone, relative to the cervical column. The position of hyoid bone of Cl III was more anterior than that of a II 3. in comparison of vertical position of hyoid bone relative to mandible. There was no significant correlation aumoug the groups of malocclusion. 4. ANB and Wits showed no significant correlation with hyoid bone position. 5. The relative extension of head, which was noted in Cl II, showed negative with Sum, ANB. 6. In Cl II and Cl III, Post to Ant facial height showed positive correlation with NSL/VER.

BACKGROUND: One of the unique feature of ambulatory blood pressure monitoring is its ability to describe the variations of BP throughout the day and night. Left ventricular hypertrophy and other measures of target organ damage in hypertension are more closely related to the average 24-h BP than to clinic BP. In addition to the mean levels of BP, the characteristics of the 24-h BP profile might be a further determinant of organ in essential hypertension. METHODS: Data were obtrained from 105 patients with essential hypertension and 44 normal subjects. Echocardiography and 24 hour ambulatory blood pressure monitoring were performed in all subjects. At first, relative wall thickness(RWT) and left ventrcular mass index were calculated from normal subject and normal values(RWT<0.44, LV mass index,120gm/m2) were applied to hypertensive patients which were classified to dipper and non-dipper according to the result of ambulatory monitoring. RESULTS: 1) There were 49 dippers and 56 non-dipper in hypertensive patients subjects. 2) Among the dippers, left ventricular mass index and relative wall thickness were normal in 51%, whereas 8.2% had increased relative wall thickness with normal ventricular mass(concentric remodeling), 32.7% had increased mass with normal relative wall thickness(eccentric hypertrophy) and 8.2% had typical hypertensive concentric hypertrophy. 3) Among the non-dippers, left ventriculat mass index and relative wall thicksness were normal in 40%, whereas 41.8% had eccentric hypertophy, 16.4% had concentric hypertrophy, only 1.8% had concentric remodeling. 4) The incidence of concentric hypertophy was significantly increased in non-dipper subjects(15.2%) than dippers(8.2%), especially in non-dipper female patients. 5) The incidence of concentric remodeling was increased in dipper(8.2%), especially in dipper female patients. 6) There were no difference between left ventricular geometies in duration of hypertension, ejecton fracton, fractional shortening, and cardiac index. 7) There were no difference between dipper and non-dipper subjects in total peripheral resistance except dipper female patients(1,484+/-535 dynes.s.cm5). CONCLUSION: Patterns of left ventricular hypertophy and geometric remodeling in essential hypertension may not be influenced by the duration of hypertension, but by gender, blood pressure level, diurnal rhythm and total peripheral resistance.

We experience a case of 34-year-old Turner's syndrome(45, XO) associated with atrial septal defect(secondum type) and mitral valve prolapse who was admitten due to moderate exertional dyspnea. It is well know hat chromosomal abnormality is one of the etiology of congenital heart disease. In case of Turner's syndrome, coarctation of aorta or bocuspid aortic valve is frequently combined, but atrial septal defect simultaneously with mitral valve prolapse is not reported till now in Krea. We report this case with a brief review of the literature.

BACKGROUND: This clinical trial was performed to evaluate the hemodynamic and side effects of enoximone, a newly developed phosphodiesterase inhibitor, in moderately severe congestive heart failure in Korean population and to base the development of long acting oral preparations in the future. METHODS: Principal admission criteria for this trial were a left ventricular ejection fraction of less than 45% by radionuclide ventriculography, NYHA functional class II or III and a documented congestive cardiomyopathy. Exclusion criteria were restrictive cardiomyopathy, valvular heart disease, multisystemic lillness and uncontrolled ventricular tachyarrhythmia. The hemodynamic measurements were made by using the thermodilution Swan-Ganz catheter and radial arterial canulation. Enoximone was administered(continuous infusion) for 24 hours after initial bolus. The hemodynamic parameters to be observed were blood pressure, heart rate, cardiac output, pulmonary capillary wedge pressure, systemic and pulmonary vascular resistance. The clinical reponse, hematology, blood chemistry, and Holter monitoring were checked before and after enoximone trial. RESULTS: The following results are obtained. 1) The included patients were 15 females, 24 males, total 39 patients and mean age of 55.3 years old(28-70 years old). 2) The causes of congestive cardiomyopathy were idiopathic 35(89.9%), hypertensive 3(7.7%), and alcoholic 1(2.6%). 3) The mean ejection fraction measured by radionuclide left ventriculography were 28. 6%. 4) THe cardiac output was significantly increased(50%), and pulmonary capillary wedge pressure(38%), systemic vascular resistance(34%), pulmonary vascular resistance(27%) were significantly decreased during enoximone infusion. 5) NYHA Functional Class was improved by 1 step with enoximone. 6) There were no significant changes in hematology, blood chemistry, and Holter monitoring with enoximone. CONCLUSION: From the above results, the short term intravenous enoximone was very effective in moderately severe congestive heart failure in congestive cardiomyopathy without major adverse effects in Korean.

PURPOSE: To investigate the postural change of intraocular pressure (IOP) from sitting to supine position and determine the relationship to other ocular parameters including ocular pulse amplitude (OPA) in glaucoma suspect and open angle glaucoma patients. METHODS: The present study included 46 eyes of 46 patients. First, we measured IOP and OPA using Goldmann applanation tonometer (GAT), Pascal dynamic contour tonometer and TonoPen(R). Using TonoPen(R), the IOP was measured immediately after the subjects were placed in a supine position and 10 minutes and 30 minutes thereafter. We also investigated the correlation between positional change of IOP and axial length (AL), refractive error (RE), and OPA. RESULTS: IOPs of patients in a sitting position measured with GAT and TonoPen(R) were 15.3 +/- 3.3 mm Hg and 16.6 +/- 2.9 mm Hg, respectively, and OPA was 2.57 +/- 0.89 mm Hg. IOPs measured with TonoPen(R) were 17.6 +/- 2.9 mm Hg immediately after position change, 18.2 +/- 3.7 mm Hg after 10 minutes and 17.5 +/- 2.7 mm Hg after 30 minutes. Each IOP change was statistically significant and the largest change was after 10 minutes. Changes of IOP after 10 minutes were positively correlated with OPA (R = 0.340) and RE (R = 0.330) and negatively correlated with AL (R = -0.410). CONCLUSIONS: When placed in a supine position, the IOP of patients increased and then decreased over time. Positional IOP change was influenced by AL and OPA and variable hemodynamic factors and apparently influenced OPA and ocular perfusion pressure.
