Six cases with Straight back syndrome were reported and studied by physiological, radiological electrocardiographic, phonocardiographic and echocardiographic evidences. They were classified according to A-P diameter and arch distance as Type I, II, III. by Kim's Consideration. 1. It was noticed that "pancake" configuration of heart with or without LVH in chest PA view with subsequent compression of the heart against the sternum and straight thoracic vertebra in lateral view was revealed. 2. Anterior-posterior diameter, and A-P/T ratio of six patients were below the average value. 3. Grade 2-3/6 ejection type systolic murmurs on pulmonary artery area and lateral sternal border or apex were auscultated, but systolic murmur on apex was considered to be insignificant due to normal mitral valve motion by Echocardiogram. 4. On ECG, there was observed one case with atrial fibrillation and the other with sinus bradycardia who had prominant straight thoracic vertebra. 5. There was observed normal mitrla valve motion on Echocardiogram in all six cases.

To evaluate the change of corneal sensation following LASIK, the corneal sensation of 26 eyes(14 patients) were examined before and 1 week, 2 week, 1 month, 2 month, 3 month, and 6 month after LASIK. The corneal sensation was measured on the following points of the center, temporal, inferior, nasal, and superior side with an esthesiometer of Cochet-Bonnet type. Each measurement of side point was taken 3mm apart from corneal center. The eyes were divided into two groups; group I was eyes with a corneal ablation depth under 100micrometer and group II was those with a value over 100micrometer. Corneal sensations in all cases were not recovered to the level of preoperation until 6 month after LASIK. The pattern of recovery was indifferent among the various points on the cornea except for the hinge side, which has shown more rapid recovery than any other area. The recovery speed between the hinge side and other areas was statistically significant(P<0.05). A decrease of corneal sensation was more prominent in group I than group II. With these results, we are able to suggest that lamellar cut of the cornea by LASIK procedure makes a damage on the corneal sensation and the depth of ablation might cause an influence on the amount of loss and recovery of the corneal sensation.

This study was carried out to evaluate the effect of electrocauterization on corneal astigmatism after cataract operation with temporal incision. Forty-two eyes of patients undergoing routine phacoemulsification with one piece type polymethymethacrylate(PMMA) posterior chamber lens implantation with 6.0mm temporal scleral pocket incision and sutureless method by one surgeon were randomly selected Corneal astigmatism was evaluated for postoperative 3 months and analyzed by Cravy`s vector method. Both groups(electrocauterization group and no electrocauterization group) showed slight with-the-rule change of corneal astigmatism till postoperative 3 months and electrocauterization group showed +0.31D at postoperative 3 months but these differences were not statistically significant(student`s t-test: p=1.10). This results demonstrate that the scleral electrocauterization at temporal incision site induced more with-the-rule change than no cauterization group.

OBJECTIVE: To compare the age of menarche, changing patterns of the menstrual characteristics in adolescent girls between 1988 and 1998. METHODS: A survey was undertaken for 1,500 highschool girls and compare with those of pervious study for 5,000 middle and highschool girls performed by same author in 1998 by means of questionnaire. RESULTS: During a decade, the mean menarcheal age decreased from 13.5+/-1.0 to 12.7+/-1.0 years(p=0.001). Gynecologic age, Body mass index were associated with age of menarche in both 1988 and 1998. The interval of menstruation was 30.6 3.5dyas in 1998 and shortened compared with 32.1+/-6.3 days in 1988(p=0.001). The duration of menstruation was lengthened in 1998 than in 1988(6.1+/-1.1 days vs 5.8+/-2.2 days, p=0.001). The incidence of irregular cycle(28.2% vs 58.2%, p=0.001), dysmenorrhea(73.9% vs 77.8%, p=0.001), and secondary amenorrhea(16.2% vs 27.2%, p= 0.001) decreased in 1998 compared with those of 1988. The incidence of agonies about menstruation was also decreased in 1998 than in 1988(26.2% vs 69.1%, p=0.001). The most common agony about menstruation in 1988 was irregular cycle(28.4%), but dysmenorrhea( 64.3%) in 1998. CONCLUSIONS: From the above results, the mean age of menarche was advanced since last decade but most of the adolescent girls still have suffered from dysmenorrhea.
