BACKGROUND: The pediatric CPR is rather uncommon practice than adult CPR in emergency room. Therefore, few interest and studies were focused in pediatric CPR. The object of this study is to make an analysis about pediatric CPR performed within hospital setting. METHOD: From January 1. 1990 to December 31. 1996, a total of 59 patients, less than 15-year-old, who received cardiopulmonary resuscitation were subject of this study. The study was done retrospective chart analysis for sex, age, weight, the place of cardiac arrest, initial EKG rhythms, endotracheal tube size, the causes of arrest, CPR time, ROSC, the amount and types of CPR drugs used during resuscitation. Wilcoxon rank sum test and chi2 test were used to compare the dose of drugs during CPR in each group. RESULTS: There were no statistical difference between ROSC and non-ROSC group in place of arrest, initial EKG rhythms, CPR time, dosage of CPR drugs. CONCLUSION: The uniform reporting guideline of pediatric advanced life support should be used for future pediatric CPR study, such as Utstein style guideline in pediatric CPR.

The "flosting knee" is the term applied to the flail knee joint segment resulting from a fracture of the shaft of adiacent metanhysis of the ipsilateralfemur and tibia. The various methods of treatment of the "floating knee" were adapted by many authors according to degree of the comminution, degree of the soft tissue injury, general condition state of the fracture. Authors experienced the floating knee in 52 cases on 51 patients who were treated at Soon Chun Hyang University Hospital in the period of 4 years and 5 months from January 1985 to June 1989 and among them, 45 cases were treated by operative method and 7 cases by conservative methods at least one of the femur and tibia, The results were as follews;1. Floating Knee occured six times more in male and the peak age was third and fourth decades. 2. The most common cause of fractures was traffie aecident and there was difficulty in diagnosis of ligamentous disruption of the ipsilateral knee. 3. The common fracture site were middle one third and the most common fracture shape was comminuted in both femur and tibia. 4. A good or excellent functional result was aohieved in treated with open reduction and rigid fixation of both fracture and there were no significant difference in group of the internal fixation of both femur and tibia. 5. Intramedullary nailing on the femur and plate fixation on the tibia provided rigid fixation of fracture and the it made possible early joint motion exercise and ambulation and the average healing time of fracuture was much shortened. 6. The most common concomitant injury were soft tissue injury and delayed or nonuion and osteomyelitis were developed more frequently in the plate and screw fixation group of the open fracture.

BACKGROUND AND OBJECTIVES: Coffee is one of the most popular beverages in the world. Caffeine is one of the substances contained in coffee and it is well known to increase blood pressure and the peripheral vascular resistance, in part because it stimulates the sympathetic nervous system. Arterial stiffness is an important factor for the performance of the cardiovascular system and it is an independent prognosticator of cardiovascular disease. We investigated the acute effect of caffeine on arterial stiffness in young healthy subjects. SUBJECTS AND METHODS: We enrolled 20 young healthy subjects, who were randomly divided two groups. The caffeine group (10 subjects, 4 males, mean age: 23.3+/-1.1 years) received 520 mL caffeinated coffee and the control group (10 subjects, 4 males, mean age: 23.1+/-1.3 years) received 520 mL water. The arterial stiffness was evaluated by the carotid-radial pulse wave velocity and the augmentation index as corrected by heart rate (75 bpm), and all the hemodynamic measurements were obtained at baseline, 30, 60, 120 and 180 minutes after ingestion of the coffee or water. RESULTS: Arterial stiffness measured by carotid-radial pulse wave velocity increased progressively from 9.4+/-1.2 m/sec at baseline to 11.5+/-1.6 m/sec (p<0.05) at 30 minutes after the coffee intake. In addition, peripheral systolic pressure increased progressively from 107.1+/-10.2 mmHg at baseline to 114.4+/-12.9 mmHg (p<0.05) at 60 minutes after the coffee intake. Such changes were not seen in control group. CONCLUSION: Caffeine affects increased the pulse wave velocity and systolic blood pressure. This means that coffee might have an adverse effect on arterial stiffness.

We report a case of thoracic post-herpetic neuralgia which was improved by dorsal root ganglionectomy. The patient had failed to obtain adequate pain relief from conservative therapy such as carbamazepine, amitriptyline, thioridazine, gabapentin, and transcutaneous lidocaine infiltration. Thoracic dorsal root ganglionectomy from T5 to T7 on left side was performed and satisfactory pain relief without significant postoperative neurologic deficit was achieved. Although dorsal root entry zone operation for refractory pain was the most commonly performed procedure in past, dorsal root ganglionectomy is an alternative anatomically and technically safe procedure for the pain in the thoracic lesion. The clinical feature, operative technique and clinical result are presented with review of the literatures.

Laser in situ keratomileusis(LASIK) composed of corneal flap and excimer laser photorefractive keratectomy(PRK) has been used for correction of high myopia. Among many kinds of excimer laser, VISX STAR has advantages like correction of cylindrical astigmatism and prevention of central island. We evaluate the effects and clinical course of LASIK using SCMD microkeratome and VISX STAR on 105 myopic eyes under -7.00D from Dec. 1996 to July 1997. The range of refractory error was from -7.00D to -15.00D and age was from 21yrs to 44yrs(mean age was 28.6yrs). The attempted correction of refractory error was determined depending on cycloplegic refraction. We evaluated the change of uncorrected visual acuity, best corrected visual acuity, spherical equivalent, astigmatism, corneal topography before operation, one day, one week, two months, and six months after operation. Uncorrected visual acuity was improved from 0.05 to 0.77, whereas best corrected visual acuity was decreased slightly from 0.92 to 0.85. Spherical equivalent was changed from -10.07 to -0.38D. However, change of cylindrical error was from -1.22D to -1.06D. This difference was not statisyically significant(p>0.05). 105 high myopic eyes were divided into two groups, in which one group was from -7.00D to -10.00D and the other group was from -10.00D to 15.00D. These two groups were compared in the point of effect of LASIK on visual improvement and correction of refractory error, retrospectively. However, there was no statistically significant differences of clinical results between two groups. With these results, it was found that LASIK using VISX STAR would be an excellent procedure for visual improvement and correction of refractory error in high myopia. However, the methods and technology would be required to control underlying astigmatism in VISX STAR system.

Laser in situ kratomileusis(LASIK) is a prefered method to excimer laser photorefractive keratectomy (PRK) because the former cuts only corneal stroma, while the latter cuts corneal epithelium, Bowmans membrane, and stroma, LASIK is a complex procedure composed of corneal flap preparation and photo-ablation. In corneal flap preparation, two types, manual and automatic, of microkeratomes have been used. We experienced problems during and after LASIK procedure using a manual microkeratome in learning curve period(8 months) and criticized the problems to shorten a learning curve of manual microkeratome. One hundred eighty six myopic eyes treated with LASIK using manual microkeratome(MLK, SCMD, USA) from January 1997 to August 1997 by one operator(Joo) were subjects. Problems occurred in 24 eyes(12.9%) and consisted of hole in corneal flap (5 eyes), thin corneal flap(3 eyes), winkling of corneal flap (2 eyes), hinge inside optical zone of laser(3 eyes), haze of interface (3 eyes), and free corneal flap(8 eyes). Majority of complications occurred in the first 3 months and most complicated cases were preventable when the speed of microkeratome enhancement was slow in late series of study. It seems that a manual microkeratome takes longer learning curve than automated microkeratome. Therefore, to decrease the number of problem cases in learning curve of LASIK using manual microkeratome a didatic course, advices from experienced surgeons, and participation in wet lab would be mandatory.

PURPOSE:To evaluate the prognosis of vision and the development of amblyopia in primary congenital glaucoma patients. METHODS: The author reviewed 38 eyes of 22 primary congenital glaucoma patients and evaluated variables such as age at time of surgery and at the last visit, preoperative IOP, Cup-to-disc(CD) ratio, corneal diameter, refractive error, axial lengths and IOP, CD ratio and visual acuity at the last visit. According to visual acuity, the patients were divided into 3 groups, good (>0.5), fair (0.1~0.5), and poor (<0.1). The amblyopia was defined when BCVA was below 0.8 and no evidence of progression of glaucoma. There were 4 types of amblyopia: deprivation, anisometropic, strabismic and organic. The author compared the 3 groups and evaluated factors affecting the vision as well as the prevalence of amblyopia. RESULTS: There were 17 eyes in the good group, 4 eyes in the fair group and 17 eyes in the poor group (p<0.05). Amblyopia developed in 17 eyes with 7 eyes showing deprivation amblyopia. Anisometropic and organic amblyopia were each found in 4 eyes, and strabismic amblyopia was found in 2 eyes. The postoperative IOP and CD ratio and preoperative CD ratio were significantly lower in the good group than the other groups (p<0.05). CONCLUSIONS: Final VA was poor in 45% of eyes with primary congenital glaucoma, and amblyopia developed in 45% of these eyes. The prognosis for vision may be related to the treatment of glaucoma and amblyopia.

Prurigo pigmentosa(PP) is a rare dermatosis with an unknown cause characterized by intensely pruritic papules that resolve with reticulate pigmentation. It is a disease entitity commonly reported in Japan but seemingly rare in other parts of the world. We report 5 cases that clinically and histopathologically fulfilled the characterisitics of PP and were treated with dapsone resulting in significant clinical improvement.
