Proliferative fasciitis is a benign pseudosarcomatous mesenchymal lesion occurring in the subcutis. The lesion occurs clinically as a tumorous mass that develops within a rather short time in elderly patients. We recently experiecened a case of fine needle aspiration cytology of proliferative fasciitis in the left anterior chest wall of a 72 year-old male patient. The smear revealed two types of cells. One was the large and mostly oval cell with one or two nuclei lying at the periphery of the cell body and abundant basophilic cytoplasm like the ganglion cell. The nuclei were round to oval, had vesicular chromatin and contained prominent nucleoli. The other was the spindle shaped fibroblast with an oval nucleus. The differential diagnosis includes a true tumor such as ganglioneuroma, rhabdomyosarcoma, and liposarcoma and therefore fine needle aspiration cytology is very much indicated in order to exclude these possibilities.

This study was conducted to determine the electromyographic features in the perioral muscles of class II division 1 malocclusion with incompetent lips, and to grope the correlation between its activities and craniofacial morphology. In this study, 14 subjects with class II division 1 malocclusion with incompetent lips(mean age of 20.5 years) and 20 subjects with normal occlusion(mean age of 23.9 years) were investigated. Electromyographic data were recorded from orbicularis oris, mentalis, buccinator and suprahyoid muscles durig rest lip posture, lip position at sealing, maximum sealing, maximal blowing, maximal biting, sipping milk, sipping and swallowing milk, chewing gum, masticating almond, swallowing almond and phonation utilizing the Medelec MS-25 electromyographic apparatus. Lateral cephalometric radiographs were taken with the mandible in intercuspal position on all subjects. All data were recorded statistically processed. The findings of this study can be summerized as follows: 1. In class II division 1 malocclusion with incompetent lips, the overall augmentations of perioral muscle activities during various functional movements set for lip sealing were manifested and particular swelling in mentalis activity at rest was detected. 2. On the other hand remarkable diminution of upper lip activities at lip sealing movements was drawn. 3. In Class II division 1 malocclusion with incompetent lips, negative correlations existed between the diversity of upper lip activities and upper incisor position and overjet as well in contrast to positive correla?tions in the lower lip. 4. It was suggested that the abnormal function of lower lip and mentalis muscle contributed somewhat the revelation of the characteristics of Class II division 1 malocclusion.

Slipped capital femoral epiphysis is a rare disease in Korea, but the incidence has being increased according to the changes of body contour and life style. Now we have more concern about slipped capital femoral epiphysis, especially the factors which contribute to the final result of treatment. Many factors such as severity of slip, stability of slipped epiphysis, whether closed reduction was done or not, whether severe complication like avascular necrosis or chondrolysis has occurred or not have effect on the result. We analyzed 20 cases of slipped capital femoral epiphysis, which occurred in 16 adolescence in view of which factors contributed to the final satisfactory result. In our study, the difference in the duration of symptoms, instability of slipped epiphysis, patients age, association with obesity or acute trauma and the number of pins had much effect on the final results and whether the reduction was done or not, the kinds of pins and association with endocrinopathy made a little difference. But further studies are necessary because the number of cases is not sufficient and the length of follow up period is not long.

It has been submitted that different ion solutions containing sulfate induce crystal growth and might substitute conventional acid etching for pretreatment of enamel in orthodontic bonding(Artun et al., Am. J. Orthod. 85, 333, 1984). This investigation was designed to evaluate the relevance of crystal growth on the enamel surface as an alternative to conventional acid etching in direct bonding of orthodontic brackets. Annexing Li2SO4, MgSO4, KeSO4 respectively in the solution with 25% polyacrylic and 0.3M sulfuric acids were employed to enhance the crystal growth. Human bicuspids were treated with various parameters as combinations of crystal growth and glass ionomer cement, crystal growth and orthodontic resin, acid etching and orthodontic resin for an inveatigative purpose. Crystal growth solution cintaining MgSO4 showed the highest shear bond strength(15.6MPa) wuthin the groups of bonding brackets with glass ionomer cement(P<0.01). Bonding with glass ionomer cement on the surface treated with crystal growth solution containing MgSO4 or K2SO4 was not different shear bond strength statistically from bonding with orthodontic resin on the acid-etched surface. It suggests that bonding brackets with glass ionomer cement on the surface treated with crystal growth solution containing MgSO4 or K2SO4 is a potential altermative to bonding with resin on the acid etched sufrace.

Background: Hyperglycemia during cardiopulmonary bypass may increase the incidence and severity of neurologic deficits that may result from cerebral ischemia. Moderate hyperglycemia has been noted to occur in pediatric patients undergoing cardiac surgery despite measures such as eliminating dextrose from the CPB clear pump priming solution and from the intra-operative iv fluids. To ameliorate the hormonal and hemodynamic stress responses during cardiac surgery in neonates, infants and children, high dose fentanyl anesthesia is widely used. The authors wished to determine prospectively whether fentanyl dosage is associated with reduced blood glucose or not in pediatric patients undergoing cardiac surgery. METHODS: Twenty four pediatric patients undergoing cardiac surgery were allocated randomly into 3 groups who received 25 g/kg fentanyl, 50 g/kg fentanyl or 75 g/kg fentanyl before CPB. The changes of plasma glucose and insulin levels were observed after sternotomy, on bypass, 30 min after bypass, off bypass, and the end of the operation. RESULTS: Blood glucose levels were not increased after sternotomy, but significantly increased at bypass to the end of the operation in all fentanyl dosage groups. Plasma insulin level increased, but statistically not significant. Different fentanyl dosage (25~75 g/kg) is not associated with differences in blood glucose level. CONCLUSION: At a dosage of 25~75 g/kg fentanyl anesthesia during pediatric open heart surgery were associated with no differences and below 250 mg/dl of blood glucose level and no significant changes in insulin level.

The development of endotracheal tubes with high-volume and low-pressure cuffs has decreas ed the incidence of associated tracheal injury. If room air used for inflation of the cuff during general anesthesia using N2O-O2, mixtures, however, endotracheal tube cuff result in distention and potential pressure changes. Therefore, tracheal pressure injury may occur during long general anesthesia(especially, head and neck surgery). For the prevention of this problems and the determination of proper methods, we performed this study relating to nitrous oxide diffusion into a gas filled endotracheal tube cuff.

PURPOSE: To present the enhancement pattern of acute cerebral or cerebellar cortical infarctions aged 1-3 days on MR. MATERIALS AND METHODS: Contrast-enhanced MR images of 26 patients with acute cerebral or cerebellar ischemic events were retrospectively reviewed. MR was performed within 3 days after ictus. RESULTS: Contrast enhancement in the area of infarction was observed in 61.5% (16/26) on MR. Of these 50% (13/26) showed non-parenchymal enhancement (NPE) representing either vascular or leptomeningeal enhancement, 7.7% (2/26) showed parenchymal enhancement (PE), and 2.8% (1/26) showed both NPE and PE. The earliest enhancement was seen in images obtained 12 hours after the onset of symptoms and appeared as NPE. One patient showed NPE without apparent high signal intensity at the corresponding area on T2-weighted images. In 38. 5% (10/26), there was no enhancement. CONCLUSION: Contrast-enhanced MR imaging may be needed in acute ischemic infarction, because NPE may be seen as the earliest MR finding of acute cortical infarction aged 1-3 days.

The frequent occurrence of hematuria in children necessitates diagnostic evaluation. Hematuria may occur with either renal or lower urinary tract disease. Clarification of the etiology of hematuria, whether microscopic or gross, is facilited by localizing the site of bleeding to the kidney (glomerular) or the lower urinary tract (non-glomerular). The mean cellular volume (MCV) of urinary red blood cells (RBCs) of pediatric patients with glomerular (group I; n=77) and non-glomerular (group II; n=34) hematuria was determined using Coulter Counter Model S plus IV. We found that re blood cells of glomerular origin had a smaller volume than non-glomerular cells(73.79 9.75 m3 vs 83.55 3.77 m3, p<0.001). If an urinary MCV equal to 80.56 m3 was taken as the cut-off value between glomerular and non-glomerular hematuria, a correct assessment of the site of bleeding was made in 89 (80%) of the 111 patients studied (sensitivity 76%, specificity 88%). The ratio of the urinary erythrocyte MCV to that in blood(Umcv/Bmcv) was compared with the diagnosis. If an Umcv/Bmcv ratio equal to 0.95 was taken as the cut-off value between glomerular and non-glomerular hematuria, a correct assessment of the site of bleeding was made in 93 (83%) of the 111 patients studied (sensitivity 79.6%, specificity 94%). Coulter counter analysis of urine provides a simple noninvasive and objective aid to the diagnosis of hematurai. This test, when used early in the management of pediatric patients with hematuria, may help to avoid invasive investigations.

Epidermolytic keratosis palmaris is a rare disease which shows clinical findings of Unna Thost keratoderma and histopathologic of epidermolytic hyperkeratosis. We report herein a case of epidermolytic keratosis palmaris et plantaris in a 16-month-old female baby. Light microscopy shows marked hyperkeratosis, large irregular keratohyalin granules, and large clear spaces in the granular and upper spinous layers. Eletron microscopic findings shows that the clear spaces are areas of cytoplasm filled with a fibrillar material and cellular organelles. Abnormal clumping of tonofilament and keratohyalin is also present.
