PURPOSE:We performed this study to compare correlation between the indices of insulin resistance using fasting insulin and glucose level and body mass index (BMI), and to determine the clinical usefulness of glucose/insulin ratio (G/I ratio), which is easily available in clinical base. METHODS:Total 119 children with simple obesity, whose BMI is over 95th percentile, were evaluated. We calculated G/I ratio, logInsulin, HOMA-IR, logHOMA-IR, and QUICKI and evaluated their relationship to BMI. RESULTS:Children with high-degree obesity had higher insulin resistance than children with mild to moderate-degree obesity (logInsulin, 1.13+/-.23 vs 1.27+/-.29; logHOMA-IR, 0.46+/-.24 vs 0.61+/-.30; QUICKI, 0.33+/-.03, 0.31+/-.03)(P<0.01), and pubertal children had higher insulin resistance than prepubertal children (G/I ratio, 7.39+/-.07 vs 4.85+/-.29; logInsulin, 1.14+/-.27 vs 1.31+/-.22; logHOMA-IR, 0.47+/-.28 vs 0.65+/-.22; QUICKI, 0.33+/-.03 vs 0.31+/-.02) (P<0.001). BMI had correlation coefficient as -0.436 for QUICKI, -0.432 for G/I ratio, 0.430 for logInsulin, and 0.425 for logHOMA-IR (P=0.000). G/I ratio was well correlated with QUICKI (r=0.901, P=0.000), logHOMA-IR (r=-0.865, P=0.000), and logInsulin (r=0.899, P=0.000). The changes of BMI were correlated with changes of G/I ratio (r=-0.547, P<0.01), QUICKI (r=-0.464, P=0.01), and logHOMA-IR (r=0.429, P<0.05). CONCLUSION: This study revealed that the degree of BMI had statistically significant correlation with insulin resistance, which can be reflected by G/I ratio, logHOMA-IR and QUICKI. G/I ratio was well correlated with logHOMA-IR and QUICKI, which suggests that G/I ratio could be used as an bedside index of insulin resistance. The changes of G/I ratio were more correlated with changes of BMI than those of logHOMA-IR and QUICKI.

INTRODUCTION: In this study, we compared sleep structure, EEG characteristic of pediatric obstructive sleep apnea (OSA) and normal controls which were matched in sex and age. METHODS: Fifteen children (male:female=4:11) who complained snoring and were suspected to have sleep apnea and their age and sex matched normal controls (male:female=5:10) have been done nocturnal polysomnography (NPSG). Sleep parameters, sleep apnea variables and relative spectral components of EEG from NPSG have been compared between both groups. RESULTS: Pediatric OSA group were distinguished from normal controls in terms of apnea index, respiratory disturbance index and nadir of oxyhemoglobulin desaturation. Pediatric OSA group showed increased percent of sleep stage 1, decreased rapid eye movement sleep percent and increased delta power in O1 EEG channel. However other sleep parameters and spectral powers were not different between two groups. CONCLUSION: In pediatric OSA group, sleep structure parameter disruption may be not prominent as the previous studies for adult OSA group because of including mild OSA data in diagnostic criteria. In addition, EEG changes might not be distinct due to low arousal index compared to adult OSA patients. We can observe general characteristics and particularity of pediatric OSA through this study.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 1999;26(5):798-803
Management of the bulbous nasal tip with inadequate projection and drooping is challenging aesthetic plastic surgery. The bulbous nasal tip is influenced by several factors; 1) thick, non-elastic oily skin, 2) soft tissue bulkiness due to supratip fibrous fatty tissue, and 3) a wide intercrural angle or increased interdormal distance. Another common factor among caucasians, hypertrophic alar cartilage, is seen less in orientals. These variable factors can be corrected with various surgical maneuvers for proper tip projection and refined alar shape. All these procedures are performed through open rhinoplasty incision. The fibromuscular fatty tissue on the nasal tip is resected with subdermal tangential excision without violating the detmal blood supply. The proximal part of the lateral crus, dome and the part of medial crus which was isolated from the skin and nasal mucosa are replaced and plicated in midline in the role of a new columellar strut and skeletal support. If more skeletal supports are desired, the new columellar is reinforced with a silicone strut and conchal cartilage onlay grafts are applied. And for lengthening of the columella, a V-Y advancement incision on the columellar base with open rhinoplasty is applied. The pressure splint on the upper third of the columella and nasal tip is applied on the 7th postoperative day and maintained for two months. All procedures are focused on the preservation of catilaginous integrity and in providing skeletal support. We performed nasal tip plasty on the bulbous nasal tip and its simple technique and predictability resulted in improved nasal tip projection and contour.

The authors analysed 196 cases of convulsive disorder in children who were admitted to the pediatric department of Kyunghee Hospital from June 1993. Blood samples were drawn immediately following seizures on arrival. Serum prolactin values were measured by radioimmunoassay. The results obtained were as follows: 1) Mean serum prolactin value was 55.4+/-20.8ng/ml in generalized seizures within 1 hr following seizures, 22.5+/-3.9ng/ml in partial seizures. There was a significant difference between generalized scizures and partial scizures (p<0.05). 2) Mean serum prolactin value was 23.5+/-9.7ng/ml in generalized seizures within 1~3 hrs following seizures, 10.4+/-4.9ng/ml in partial seizures. There was a significant difference between generalized seizures and partial seizures (p<0.05). 3) Mean serum prolactin value was 9.5+/-4.4ng/ml in generalized seizures 3 hrs following seizures, 9.8+/-4.8ng/ml in partial seizures. There was no significant difference between generalized seizures and partial seizures (p>0.05). We found transient hyperprolactinemia following generalized seizures but a little change following gartial seizures. Postictal elevation of serum prolactin may represent a biochemical marker of generalized and partial seizures.

Immunosuppressive therapy based on the use of antilymphocyte globulin (ALG) has become standard therapy for patients with splastic anemia who are not eligible for bone marrow transplantation. In this study, T cell subsets before and after ALG therapy, hematologic responses, complications and prognostic factors were analysed. Eleven (42%) out of twenty-six patients treated with ALG showed response, but two patients showed relapse. Most of the response (9 cases) was noticed within 6 months after the initiation of ALG therapy (median: 3 months). The main complications of ALG therapy were fever (91%), thrombocytopenia (86%), neutropenia (63%), and serum sickness (56%). Four patients were died just ALG therapy because of serum sickness (2 cases), intracranial hemorrhage (1 case), and shock (1 case). Short interval from diagnosis to treatment suggested to show good response (P=0.0575), but it was not significant statistically. Lymphocyte subsets were measured in the blood of 23 patients. Helper T/suppressor T cell ratio (T4/T8 ratio) at the initiation of ALG therapy (day 0) was higher significantly in patients who were responded (P=0.0299). The patients who showed above 1.0 of T4/T8 ratio on day 0 might be speculated good response (P=0.032). More difference of T4/T8 ratio between day 14 after ALG therapy and day 0 might show good response (P=0.0673). Then the actuarial probability of survival at 3 years in patients treated with ALG was 77%. Our data suggest that ALG therapy may be used as an alternative treatment to bone marrow transplantation, and T4/T8 ration of peripheral blood at the initiation of therapy may be used as one of the prognostic factors.

The immunoreactivities of surgically removed 16 cardiac myxomas were studies for factor VIII-related Ag (F VIII-RA), Ulex europaeus agglutinin I (UEA-I) and desmin alpha1-antichymotrypsin, and this study was accompained by a clinicopathologic review. More than 50% of the patients with cardiac myxomas were in their fourth and fifth decades, and cardiac myxomas were much more common in women than in men. All but on occurred in the left atrium, and the majority were attached to the atrial septum, usually in the region corresponding to the fossa ovalis. In one case, an atrial myxoma recurred 37 months after the initial excision. Microscopically, the myxomas contained a myxoid matrix composed of acid mucopolysaccharides within which were embedded polygonal cells. The cells forming both the surface and complicated vascular like channels throuhout the myxoid stroma tested positive for F VIII-RA and UEA-I. The outer cell layers of the complex vascular structures demonstrated variable staining for F VIII-RA, while isolated bundles of smooth muscle cells were present and stained for desmin. A small number of the so-called myxoma cells, immunoreactive for alpha1-antichymotrypsin which were not laden with hemosiderin pigment but were similar to histiocytes, were present particularly around the areas of hemorrhage. These findings support the current view that cellular and histologic heterogeneity arose from the divergent differentiation of multipotential mesenchymal cells. In particular, it remains to be confirmed by further study whether or not true histiocytic differentiation occurs.
