Poor R-Wave Progression(PRWP) of precordial leads is frequently encountered electrocardiographic findings of uncertain significance and has simply been deemed as suggestion of anterior myocardial infarction without concrete ground. 217 cases with poor R-Wave Progression have been analyzed on clinical records and results are as follows. 1) PRWP was most frequently found in fifties and sixities, comprising 63.9% of the subjects. 2) Co-existent disease entities with PRWP were classified into three categories, cardiovascular diseases, chronic lung diseases and normal variants. 3) The cardiovascular diseases related with PRWP were mainly hypertensive diseases, comprising 59.8% of cardiovascular diseases, followed by ischemic heart disease, valvular heart disease and cardiomyopathies. 4) PRWP may be an early sign of acute myocardial infarction in a certain part of cases, which was endorsed by typical clinical symptoms and enzyme studies. 5) As the criterion of PRWP, V3R equal to or less than 3 mm was thought more adequate for higher specificity rather than 4 mm.

The traditional treatment for the femoral shaft fractures in children is closed reduction by continuous traction, usually for 2–3 weeks, until the fracture has achieved partial stability, followed by spica cast immobilization. Fifty three cases, from 3 to 10 years of age, has been treated with closed reduction and immediate application of hip spica csst; all of them were closed fractures of femoral shaft and were not associated with head, abdominal, or vascular injuries. Any angulations in excess of acceptable ranges were corrected with wedging the cast; any overridings in excess of acceptable ranges were corrected by skeletal traction for 1 week, followed by incorporation of the pin to the cast. The resultant overriding and angulation of fragments were within acceptable ranges, and complications were not significant.This method of treatment not only is likely easy in nursing care and comfortsble to the patients but also has some advantages of short stay in the hospital, better utilization of hospital beds, and costsaving. This immediate hip spica cast immobilization seems to be a good method of treatment for the femoral shaft fracture in children.

The goals of orthopaedic management of pelvic ring injuries are to achieve anatomical reduction and secure fixation of fragment and mobilize the patient as early as possible. Previously, pelvic ring injuries have been treated by a wide variety of conservative methods. Their application, however, necessitated a prolonged period of recumbency with associated likelyhood for many complications and did not facilitate accurate reduction and stabilization of most types, resulting in pelvic deformity, non-union and late sacroiliac joint instability. During the past decade, experience with techniques of external and internal fixation of the pelvis has grown and the goals of the methods include provision for sufficient pelvic stability in satisfactory position so that immediate postoperative bed-to-chair transfers can be undertaken and complications due to prolonged recumbency and pelvic deformity can be markedly reduced. We reviewed 47 cases of unstable pelvic ring injuries treated at the depatment of orthopaedic surgery, Dongkang Hospital from January 1984 to December 1987, and the results were as follows ;1. The highest incidence was in the 4th decade and sex ratio between male and female was 1.6:1 2. The most common cause of injury was traffic accident (68.2%) followed by falling down accident (19%) 3. Associated injuries occurred in 28 cases (60%): injuries of the extremities were most common (30%) followed by head injury (13%) and genitourinary tract injury (11%). 4. According to classification of Pennal et al, lateral compression injury was most common (51.1%). Bucholz Group II injury was 57% of all and Group III, 43%. 5. Operative methods, with which 21 cases were treated, were anterior external fixation with AO apparatus or symphyseal plating in Bucholz Group II injuries ; and external fixation, internal fixation (anterior and/or posterior) or both, in Group III injuries. 6. Advantages of operative treatment of unstable pelvic ring disruptions were, by giving stability, early mobilization; easy care of associated injuries, open wounds and nursing; prevention of possible complications of prolonged recumbent position; rapid reduction of pain; and prevention of late complications such as lumbosacral or pelvic pain and gait disturbance.

A number of studies have documented the reasonable efficacy and safety of radial keratotomy, but most based upon results obtained in low or moderate myopia or short term follow up after surgery. We complied 5 year and longer follow up data on 91 consecutive radial keratotomy surgeries on high myopia (over -6.00 diopters) performed by one surgeon 5 year-follow up was obtained on 21 (23%) of these eyes. The mean spherical equivalent before surgery was -11.02 diopters (D), the average keratometry value was 44.40 D, and all of the eyes had an uncorrected visual acuity of 0.04 or less. The average change in spherical equivalent was 3.44 D for eyes examined at 1 year, compared with 3.05 D for eyes at 3 years and 2.87 D at 5 years after surgery. Average keratometry value were 42.30 D at 1 year, 41.60 D at 3 years, and 41.30 D at 5 years after surgery. In our study, the decrease in spherical equivalent of 0.57 D was statistically significant (P < 0.05), as was the reduction in average keratometry value of 1.00 D. The effect of the surgery on spherical equivalent continued to regress through all the 5 years of follow up. However, the keratometric measurement decreased up to 5 years which indicated progressive flattening of the cornea. Also we divided these eyes into 2 groups, lower-myopic group (-6.00 D~-9.75 D) and higher-myopic group (over -10.00 D). In each category, the changes in spherical equivalent were 3.60 D, 2.21 D at 5 years, compared with 3.65 D, 3.25 D at 1 year respectively. The efficacy of radial keratotomy was lower, and the change of spherical equivalent between 1 year and 5 years was larger in the higher-myopic group than in the lower-myopic group. The results show that both radial keratotomy effectiveness and long term stability decrease in higher myopic cases.
