Background:
The study aimed to compare the growth responses to 3 years of growth hormone (GH) treatment in children and adolescents with GH deficiency (GHD) according to idiopathic, organic, isolated (IGHD), and multiple pituitary hormone deficiency (MPHD).
Methods:
Total 163 patients aged 2–18 years (100 males and 63 females; 131 idiopathic and 32 organic GHD; 129 IGHD and 34 MPHD) were included from data obtained from the LG Growth Study. Parameters of growth responses and biochemical results were compared during the 3-year GH treatment.
Results:
The baseline age, bone age (BA), height (Ht) standard deviation score (SDS), weight SDS, mid-parental Ht SDS, predicted adult Ht (PAH) SDS, and insulin like growth factor-1 (IGF-1) SDS were significantly higher in the organic GHD patients than in the idiopathic GHD patients, but peak GH on the GH-stimulation test, baseline GH dose, and mean 3-year-GH dosage were higher in the idiopathic GHD patients than in the organic GHD patients. The prevalence of MPHD was higher in the organic GHD patients than in the idiopathic GHD patients. Idiopathic MPHD subgroup showed the largest increase for the ΔHt SDS and ΔPAH SDS during GH treatment, and organic MPHD subgroup had the smallest mean increase after GH treatment, depending on ΔIGF-1 SDS and ΔIGF binding protein-3 (IGFBP-3) SDS.The growth velocity and the parental-adjusted Ht gain were greater in the idiopathic GHD patients than the organic GHD patients during the 3-year GH treatment, which may have been related to the different GH dose, ΔIGF-1 SDS, and ΔIGFBP-3 SDS between two groups.Multiple linear regression analysis revealed that baseline IGF-1 SDS, BA, and MPH SDS in idiopathic group and baseline HT SDS in organic group are the most predictable parameters for favorable 3-year-GH treatment.
Conclusion
The 3-year-GH treatment was effective in both idiopathic and organic GHD patients regardless of the presence of MPHD or underlying causes, but their growth outcomes were not constant with each other. Close monitoring along with appropriate dosage of GH and annual growth responses, not specific at baseline, are more important in children and adolescents with GHD for long-term treatment.

In case of young women treated with ovarian preservation in cervical cancer surgery, it is regarded pertinent to reduce the risk of early menopause resulting from adjuvant pelvic irradiation through ovarian transposition. On the other hand, lots of authors have raised questions in regard with the ovary being possibly affected by micrometastasis. Studies have reported appropriate indications of ovarian transposition and risk factors of ovarian metastasis to cope with this problem. We conducted ovarian transposition with cervical cancer patient who had no ovarian metastasis risk factors reported in previous literature and experienced such case that metastasis took place only in the ovary without spreading to other organs. This study is to report that case based on brief literature review.

Background and Objectives:
The prognostic implications of septic cardiomyopathy have not been clearly demonstrated. We evaluated serial changes in left ventricular (LV) and right ventricular (RV) function in patients with septic shock and their prognostic value on 7-day and in-hospital mortality.
Methods:
Transthoracic echocardiography was performed within 48 hours of the diagnosis of septic shock and 7 days after the initial evaluation. In addition to traditional echocardiographic parameters, LV and RV function was evaluated using global longitudinal strain (GLS), and tricuspid annular plane systolic excursion (TAPSE).
Results:
A total of 162 patients (men, 83, 51.5%; 70.7±13.4 years; Acute Physiology and Chronic Health Evaluation [APACHE] II, 30.6±9.2) were enrolled. Initial GLS and TAPSE were −14.9±5.2% and 16.9±5.5 mm, and improved in the follow-up evaluation (GLS, −17.6±4.9%;TAPSE, 19.2±5.4 mm). Seven-day and in-hospital mortality were 24 (14.9%) and 64 (39.8%).Seven-day mortality was significantly associated with initial GLS >−16% (odds ratio [OR], 14.066, 95% confidence interval [CI], 1.178–167.969, p=0.037) and APACHE II score (OR, 1.196, 95% CI, 1.047–1.365, p=0.008). The in-hospital mortality of 7-day survivors was associated with follow-up TAPSE <16 mm (OR, 10.109, 95% CI, 1.640–62.322, p=0.013) and Sequential Organ Failure Assessment score (OR, 1.340, 95% CI, 1.078–1.667, p=0.008). GLS was not associated with in-hospital mortality of 7-day survivors.
Conclusions
Fluctuation of both ventricular function was common in septic shock. Sevenday mortality of patients with septic shock was related to GLS, whereas in-hospital mortality of 7-day survivors was related to TAPSE, not to GLS.

PURPOSE: To determine predictive factors for stent failure-free survival in patients treated with a retrograde ureteral stent for a malignant ureteral obstruction. MATERIALS AND METHODS: We retrospectively reviewed 71 patients who underwent insertion of a cystoscopic ureteral stent due to a malignant ureteral obstruction between May 2004 and June 2011. Performance status, type of cancer, hydronephrosis grade, location of the obstruction, presence of bladder invasion, C-reactive protein (CRP), serum albumin, and inflammation-based prognostic score (Glasgow prognostic score, GPS) were assessed using a Cox proportional regression hazard model as predicting factors for stent failure. RESULTS: A univariate analysis indicted that hypoalbuminemia (<3.5 g/dL; hazard ratio [HR], 2.43; 95% confidence interval [CI], 1.21 to 4.86; p=0.012), elevated CRP (> or =1 mg/dL; HR, 4.79; 95% CI, 2.0 to 11.1; p=0.001), and presence of a distal ureter obstruction (HR, 3.27; 95% CI, 1.19 to 8.95; p=0.021) were associated with stent failure-free survival. A multivariate analysis revealed that the presence of a mid and lower ureteral obstruction (HR, 3.27; 95% CI, 1.19 to 8.95; p=0.007), GPS > or =1 (HR, 7.22; 95% CI, 2.89 to 18.0; p=0.001), and elevated serum creatinine before ureteral stent placement (>1.2 mg/dL; HR, 2.16; 95% CI, 1.02 to 4.57; p=0.044) were associated with stent failure-free survival. CONCLUSIONS: A mid or lower ureteral obstruction, GPS > or =1, and serum creatinine before ureteral stent insertion >1.2 mg/dL were unfavorable predictors of stent failure-free survival. These factors may help urologists predict survival time.

OBJECTIVE: Uterine papillary serous carcinoma (UPSC) has been recognized as an aggressive tumor characterized by deep myometrial invasion and reported high recurrence and low survival rates. METHODS: We retrospectively investigated the clinicopathologic findings and analyzed the survival rate and prognostic factors in 25 patients with UPSC who were surgically staged at the oncology department between January 1994 and December 2003. RESULTS: The mean age of the cases was 55.8 (range: 45-69) years. The most frequent presenting symptom was abnormal uterine bleeding (88%). According to FIGO staging, seven of the cases were stage I, six of the cases were stage II, eleven of the cases were stage III, and one case was stage IV. Mean follow up period is 42.7 months (range: 9-123 months). Overall survival rate was 80 percent. The recurrence was seen in 5 patients (25%). CONCLUSION: Univariate analysis showed that invasion of uterine serosa, ovarian and tubal metastasis, and positive peritoneal washing cytology were significantly associated with prediction of prognosis. In multivariate analysis, tubal metastasis was an independent prognostic factor for overall survival.

OBJECTIVE: The aim of the study is to determine the clinical characteristics and management of primary fallopian tube malignancies together with the results there unto that had been diagnosed and treated in Samsung Cheil Hospital oncology department retrospectively. METHODS: The fifteen cases of fallopian tube malignancies, of a total of 3495 gynecologic malignancies (0.043%) that has been diagnosed in or referred to our hospital between January 1993 and December 2004 were evaluated retrospectively. We investigate the clinicopathologic findings and analyze the survival period for 15 patients with primary fallpian tube malignancies who were surgically operated. RESULTS: The mean age of patients is 53.47 years. Most frequent application symptoms of the cases are pelvic mass (46.7%) and abnormal uterine bleeding (40%). The staging laparotomy was done in 12 patients. According to FIGO staging, seven of the cases are stage I, six of the cases are stage III, and one of the cases is borderline malignancy. Adjuvant chemotherapy was applied 13 cases and adjuvant radiotherapy was applied one case. Mean follow up period of the cases is 27.8 months. CONCLUSION: Primary fallopian tube malignancies are very rare malignancies. Diagnosis can be made generally peri or postoperatively. More extensive clinical research must be performed in order to have definite etiologic diagnostic management modalities and prognostic markers.

OBJECTIVE: This multi-center, randomized, double-blind, phase 3 trial was conducted to compare the safety and efficacy of contrast agents iohexol-380 and iohexol-350 for coronary CT angiography in healthy subjects. MATERIALS AND METHODS: Volunteers were randomized to receive 420 mgI/kg of either iohexol-350 or iohexol-380 using a flow rate of 4 mL/sec. All adverse events were recorded. Two blinded readers independently reviewed the CT images and conflicting results were resolved by a third reader. Luminal attenuations (ascending aorta, left main coronary artery, and left ventricle) in Hounsfield units (HUs) and image quality on a 4-point scale were calculated. RESULTS: A total of 225 subjects were given contrast media (115 with iohexol-380 and 110 with iohexol-350). There was no difference in number of adverse drug reactions between groups: 75 events in 56 (48.7%) of 115 subjects in the iohexol-380 group vs. 74 events in 51 (46.4%) of 110 subjects in the iohexol-350 group (p = 0.690). No severe adverse drug reactions were recorded. Neither group showed an increase in serum creatinine. Significant differences in mean density between the groups was found in the ascending aorta: 375.8 ± 71.4 HU with iohexol-380 vs. 356.3 ± 61.5 HU with iohexol-350 (p = 0.030). No significant differences in image quality scores between both groups were observed for all three anatomic evaluations (all, p > 0.05). CONCLUSION: Iohexol-380 provides improved enhancement of the ascending aorta and similar attenuation of the coronary arteries without any increase in adverse drug reactions, as compared with iohexol-350 using an identical amount of total iodine.

BACKGROUND: Vascular endothelial growth factor (VEGF) is associated with the development of diabetic complications. However, it is unknown whether systemic VEGF treatment has any effects on the pancreatic islets in an animal model of type 2 diabetes mellitus. METHODS: Anti-VEGF peptide (synthetic ATWLPPR, VEGF receptor type 2 antagonist) was injected into db/db mice for 12 weeks. We analyzed pancreatic islet morphology and quantified beta-cell mass. Endothelial cell proliferation and the severity of islet fibrosis were also measured. VEGF expression in isolated islets was determined using Western blot analysis. RESULTS: When anti-VEGF was administered, db/db mice exhibited more severe hyperglycemia and associated delayed weight gain than non-treated db/db mice. Pancreas weight and pancreatic beta-cell mass were also significantly decreased in the anti-VEGF-treated group. VEGF and VEGF receptor proteins (types 1 and 2) were expressed in the pancreatic islets, and their expression was significantly increased in the db/db group compared with the db/dm group. However, the elevated VEGF expression was significantly reduced by anti-VEGF treatment compared with the db/db group. The anti-VEGF-treated group had more prominent islet fibrosis and islet destruction than db/db mice. Intra-islet endothelial cell proliferation was also remarkably reduced by the anti-VEGF peptide. CONCLUSION: Inhibition of VEGF action by the VEGF receptor 2 antagonist not only suppressed the proliferation of intra-islet endothelial cells but also accelerated pancreatic islet destruction and aggravated hyperglycemia in a type 2 diabetes mouse model. Therefore, the potential effects of anti-VEGF treatment on pancreatic beta cell damage should be considered.
