PURPOSE: This study was undertaken to compare the growth promoting effect between patients with idiopathic growth hormone deficiency(IGHD) and those with organic growth hormone deficiency(OGHD). METHODS: Seventeen children with GH deficiency were divided into two groups: 7 IGHD and 10 OGHD including craniopharyngioma(5), sella germinoma(1), prolactinoma(1), Langerhans cell histiocytosis(1) and postirradiation(1). Diagnosis of GHD was made on the basis of two growth hormone provocative tests, serum IGF-1 & IGFBP 3 level, and bone age. Both groups were treated with recombinant human growth hormone(0.6-0.8IU/Kg/week) for 2 years and auxological parameters (height velocity, height SDS CA(standard deviation score for chronologic age)) were analyzed during 2 years of treatment by using KIGS 4.0 software program. RESULTS :The mean pretreatment height velocity in both groups did not differ statistically(2.6+/-.8cm/yr in IGHD vs 2.5+/-.9cm/yr in OGHD: p>0.05). However, height velocity after 2 years of growth hormone treatment was significantly greater in IGHD group than in OGHD group(9.0+/-.3cm/yr in IGHD vs 7.2+/-.8cm/yr in OGHD: P<0.05). The height SDS for CA has improved remakably during 2 years of growth hormone treatment; -3.46 SDS before treatment to -1.53 SDS in IGHD group, -2.3 SDS to -0.5 SDS in OGHD group. CONCLUSION: Growth hormone replacement therapy has remakably improved height velocity and height SDS for CA in both groups during the 2 years of the treatment. However, the height velocity in OGHD group was significantly less than in IGHD, indicating that additional factors such as malnutrition, associated multiple hormone deficiencies, spinal irradiation and sexual precocity might significantly hamper the growth promoting effect in OGHD group during growth hormone treatment.

PURPOSE: In this study, efforts have been made to evaluate the sella MRI in 14 patients with growth hormone deficiency to define more clearly the structural abnormalities of the hypothalamo- hypophyseal axis, examine frequency of these abnormalities, and determine whether a relationship exists between the sella MRI findings and types of endocrine dysfunction. METHODS: Sella MRI was performed in 14 patients who were diagnosed as growth hormone deficiency (GHD) based on a strict diagnostic criteria. If abnormal sella MR findings were associated, then combined anterior pituitary function test was carried out. RESULTS: Among the 14 patients with GHD, complete deficiency was found in 10 patients and partial deficiency in 4 patients. Three with complete GHD showed normal MRI findings and isolated GHD only. Others revealed 3 pituitary stalk interruption syndrome (PSIS), 2 hypoplastic pituitary gland, 1 prolactinoma, and 1 Langerhans histiocytosis. These patients have multiple endocrine dysfunctions in addition to GHD. Three out of 4 patients with partial GHD, showed normal sella MR findings and isolated GHD. Only one patient with partial GHD had a delayed puberty and hypoplasia of pituitary gland. CONCLUSION: Sella MRI enables us to identify mophologic pictures in GHD previously considered 'idiopathic'. Abnormal sella MR findings strongly suggest that multiple hormone deficiencies are associated. This study justifies that routine sella MRI should be recommended in an attempt to identify the etiology of GHD in case that the diagnosis of GHD is strictly made.

PURPOSE: To compare the incidence and clinical characteristics of infants with atypical CLD and those with classic BPD among premature infants less than 32 weeks' gestation. METHODS: Clinical data was collected retrospectively from the 256 premature infants less than 32 weeks' gestation and their mothers during 3-year study period. RESULTS: Among 212 preterm infants less than 32 weeks' gestation who survived to 28 days of life, 19 (9%) had atypical CLD and 38 (17.9%) had classic BPD. Atypical CLD infants were significantly heavier and more mature than classic BPD infants (mean birth weights, 1,100+/-294 g vs 915+/-225 g; and mean gestational age, 26.9+/-1.6 weeks vs 21.1+/-1.3 weeks). Duration of ventilator therapy and oxygen inhalation within 28 days of age were shorter in atypical CLD infants than in classic BPD infants (mean duration of ventilator therapy, 16.3+/-6.9 days vs 27+/-6.8 days; and mean duration of oxygen inhalation, 25.5+/-13.5 days vs 53.8+/-39 days). Oxygen dependency in atypical CLD infants showed bimodal pattern, decreasing gradually to 3-week after birth and upturning to peak at about 5-week after birth. Comparing the respiratory indices between classic BPD and aypical CLD, FiO2 at day 2,7, and 10, and oxygen index at day 2, and 10 were significant in classic BPD, but MAP were not. Considering the birth weight, MAP per birth weight, and modified oxygen index showed more apparent differencies between the two groups. CONCLUSION: 35.5% of total CLD were atypical CLD and showed bimodal pattern in oxygen dependency. Atypical CLD infants were significantly heavier and more mature than classic BPD infants.

Implant-supported overdenture is a reliable treatment option for the patients with edentulous mandible when they have difficulty in using complete dentures. Several options have been used for implant-supported overdenture attachments. Among these, bar attachment system has greater retention and better maintainability than others. SFI-Bar(R) is prefabricated and can be adjustable at chairside. Therefore, laboratory procedures such as soldering and welding are unnecessary, which leads to fewer errors and lower costs. A 67-year-old female patient presented, complaining of mobility of lower anterior teeth with old denture. She had been wearing complete denture in the maxilla and removable partial denture in the mandible with severe bone loss. After extracting the teeth, two implants were placed in front of mental foramen, and SFI-Bar(R) was connected. A tube bar was seated to two adapters through large ball joints and fixation screws, connecting each implant. The length of the tube bar was adjusted according to inter-implant distance. Then, a female part was attached to the bar beneath the new denture. This clinical report describes two-implant-supported overdenture using the SFI-Bar(R) system in a mandibular edentulous patient.

The incidence of malaria in Korea is significantly on the rise since its reemergence in 1993 and no screening test that can prevent the infection has been available. Very low birth weight infants are especially susceptible to malaria infection due to transfusions from multiple donors. We report a case of transfusion transmitted Plasmodium vivax infection in a 120-day-old infant of a gestational age 24 weeks with birth weight of 700 gm who was successfully treated with hydroxychloroquine.

BACKGROUND: Adenosine is secreted by myocardial cells during myocardial ischemia or hypoxia. It has many beneficial effects on arrhythmias, myocardial ischemia, and reperfusion ischemia. Although many investigators have demonstrated that cardioplegia that includes adenosine shows protective effects in myocardial ischemia or reperfusion injury, reports of the optimal dose of adenosine in cardioplegic solutions vary. We reported the results of beneficial effects of single dosage (0.75 mg/Kg/min) adenosine by use of self-made Langendorff system. But it is uncertain that dosage was optimal. The objective of this study is to determine the optimal dose of adenosine in cardioplegic solutions. MATERIAL AND METHOD: We used a self-made Langendorff system to evaluate the myocardial protective effect. Isolated rat hearts were subjected to 90 minutes of deep hypothermic arrest (15degree C) with modified St. Thomas' Hospital cardioplegia including adenosine. Myocardial adenosine levels were augmented during ischemia by providing exogenous adenosine in the cardioplegia. Three groups of hearts were studied: (1) group 1 (n=10) : adenosine -0.5 mg/Kg/min, (2) group 2 (n=10): adenosine -0.75 mg/Kg/min, (3) group 3 (n=10) : adenosine -1 mg/Kg/min. RESULT: Group 3 resulted in a significantly rapid arrest time of the heart beat (p<0.05) but significantly slow recovery time of the heart beat after reperfusion (p<0.05) compared to groups 1 and 2. Group 2 showed a better percentage of recovery (p<0.05) in systolic aortic pressure, aortic overflow volume, coronary flow volume, and cardiac output compared to groups 1 and 3. Group 1 showed a a better percentage of recovery (p<0.05) in the heart rate compared to the others. In biochemical study of drained reperfusates, CPK and lactic acid levels did not show significant differences in all of the groups. CONCLUSION: We concluded that group 2 [adenosine (0.75 mg/Kg/min) added to cardioplegia] has better recovery effects after reperfusion in myocardial ischemia and is the most appropriate dosage compared to group 1 and 3.

OBJECTIVE: To evaluate the clinicopathologic characteristics and prognostic factors of ovarian granulosa cell tumors. METHODS: Medical records of 113 patients presenting between January 1995 and December 2007 were retrospectively reviewed. RESULTS: One-hundred two patients had adult type disease, with a mean age of 46.2 years (range, 18 to 83 years) and a mean follow-up period of 54.7 months (range, 1 to 155 months). The distribution of FIGO stages was 86 patients at stage I, 11 at stage II, and 5 at stage III. During follow-up, ten patients recurred at a mean time of 48 months (range, 4 to 109 months). Among them, three patients died after a mean of 57 months (range, 25 to 103 months). In recurrence analysis, advanced stage (p=0.032) and presence of residual disease (p=0.012) were statistically significant, and age<40 years, premenopause and positive washing cytology were marginally significant (p<0.1). In multivariate analysis, stage was the only factor associated with recurrence; adjuvant chemotherapy and fertility-sparing surgery were not statistically significant. Among 36 patients with fertility-sparing operations, eight patients had nine pregnancies and delivered seven babies. Eleven patients had juvenile type tumors; the mean age was 20.0 years (range, 8 to 45 years) and the mean follow-up period was 69.8 months (range, 20 to 156 months). The distribution of FIGO stage was nine patients at stage I and two at stage III. There were no recurrences or deaths reported. Four patients had seven pregnancies and delivered six babies. CONCLUSION: Stage is the only factor associated with disease-free survival, and fertility-sparing surgery may be a treatment option for women with early-stage disease who want to retain fertility.

OBJECTIVE: To compare clinicopathologic characteristics and surgical outcomes of laparoscopic surgery in women with endometrial cancer according to body mass index (BMI). METHODS: From June 2009 to October 2010, prospective observational study without randomization of 159 patients treated by laparoscopic surgery from 10 hospitals nationwide. RESULTS: Patients were divided according to the WHO guidelines for Asia-Pacific populations and the distributions of BMI were as follows: 3 patients (1.9%) in underweight (BMI < 18.5 kg/m2), 50 patients (31.4%) in normal weight (BMI, 18.5-22.9 kg/m2), 45 patients (28.3%) in overweight (BMI, 23.0-24.9 kg/m2), 49 patients (30.8%) in obese (BMI, 25.0-29.9 kg/m2), and 12 patients (7.5%) in morbid obese (BMI > or = 30.0 kg/m2). Age, history of previous surgery, surgery extend, and history of previous surgery were not different between non-obese patients (BMI < 25.0 kg/m2) and obese patients (BMI > or = 25.0 kg/m2). Co-morbidities were more common in obese patients but marginally significant (23.5% vs. 37.7%, p=0.072). Four patients (2.5%) were converted to abdominal surgery because of severe adhesion. Regarding to surgical outcomes, operation time was significantly longer in obese patients (199 min vs. 235 min, p=0.013) but blood loss, lymph node yield, hospital stay, Foley removal, transfusion rate and peri-operative complication were not statistically significant. Regarding to pathologic results, there were no difference in terms of lymphovasucular space invasion, tumor grade, histologic type, lymph node metastasis and FIGO stage. CONCLUSION: Clinicopathologic characteristics and surgical outcomes does not seem to be significantly influenced by BMI except operation time. So the laparoscopic approach can be the alternative method for obese patients.
