BACKGROUND: Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT) evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration. METHODS: The medical records of 37 patients (37 orbits) with an orbital fracture with muscle incarceration from January 2001 to January 2015 were reviewed. The presence of Incarcerated muscle was confirmed via CT, as well as by intraoperative findings. Various factors potentially contributing to complications lasting for over 1 year after the injury were categorized and analyzed, including age, cause of injury, injury-to-operation time, operative time, fracture type, nausea, vomiting and other concomitant symptoms and injuries. RESULTS: All patients who presented with extraocular muscle limitations, positive CT findings, and/or a positive forced duction test underwent surgery. Of the 37 patients, 9 (24%) exhibited lasting complications, such as diplopia and gaze restriction. The mean follow-up period was 18.4 months (range, 1–108 months), while that of patients who experienced prolonged complications was 30.1 months (range, 13–36 months). Two factors were significantly associated with prolonged complications: injury-to-operation time and nausea/vomiting. Loss of vision, worsening of motility, and implant complication did not occur. CONCLUSIONS: Patients who present with gaze limitations, with or without other signs of a blow-out fracture, require a thorough evaluation and emergent surgery. A better prognosis is expected with a shorter injury-to-operation time and lack of nausea and vomiting at the initial presentation.

BACKGROUND: Prealbumin, a sensitive marker for protein–energy status, is also known as an independent risk factor for mortality in hemodialysis patients. We investigated the impact of prealbumin on survival in incident peritoneal dialysis (PD) patients. METHODS: In total, 136 incident PD patients (mean age, 53.0 ± 15.8 years) between 2002 and 2007 were enrolled in the study. Laboratory data, dialysis adequacy, and nutritional parameters were assessed 3 months after PD initiation. Patients were classified into 2 groups according to prealbumin level: high prealbumin (≥ 40 mg/dL) and low prealbumin (< 40 mg/dL). RESULTS: The patients in the low-prealbumin group were older and had more comorbidities such as diabetes and cardiovascular diseases compared with the patients in the high-prealbumin group. Mean subjective global assessment scores were lower, and the high-sensitivity C-reactive protein levels were higher in the low-prealbumin group. Serum creatinine, albumin, and transferrin levels; percent lean body mass; and normalized protein catabolic rate were positively associated, whereas subjective global assessment scores and high-sensitivity C-reactive protein levels were negatively associated with prealbumin concentration. During the median follow-up of 49 months, patients in the lower prealbumin group had a higher mortality rate. Multivariate analysis revealed that prealbumin < 40 mg/dL (hazard ratio, 2.30; 95% confidence interval, 1.14–4.64) was an independent risk factor for mortality. In receiver operating characteristic curves, the area under the curve of prealbumin for mortality was the largest among the parameters. CONCLUSION: Prealbumin levels were an independent and sensitive predictor for mortality in incident PD patients, showing a good correlation with nutritional and inflammatory markers.

BACKGROUND/AIMS: This study was performed to compare the mucosal findings after esophagogastroduodenoscopy in two groups before and after the use of alendronate only and following administration of the enteric-coated alendronate (5 mg) and calcitriol (0.5 microg) combined drug (Maxmarvil, Yuyu Co.). METHODS: The study population consisted of 33 postmenopausal healthy female volunteers, aged 50 to 70 years (mean age, 58 +/- 5) without gastrointestinal symptoms and with normal baseline endoscopic findings. Esophagogastroduodenoscopy was performed at baseline and was repeated 2 weeks later after daily intake of Maxmarvil (n = 17 subjects) or alendronate only (n = 16 subjects). Mucosal injury scores were reported by an endoscopist after 2 weeks of treatment with each medication schedule. RESULTS: Esophageal mucosal injuries developed in two of 16 subjects in the alendronate only group and 0 of 17 in the Maxmarvil group. Gastric mucosal injuries developed in eight subjects in the alendronate group and four subjects in the Maxmarvil group; this difference was statistically significant. CONCLUSIONS: The mucosal damage scores for the alendronate group (total score 24) were significantly higher than those for the Maxmarvil group (total score 9) in the esophagus and stomach. Therefore, this study suggested that enteric-coated Maxmarvil is less harmful to gastrointestinal mucosa than alendronate, and may improve the tolerability of osteoporosis medication in clinical practice.

BACKGROUND/AIMS: The relationship between Runt-related transcription factor 3 (RUNX3) gene inactivation and various solid tumors has been reported; however, little information is available about RUNX3 in thyroid cancers. METHODS: We evaluated the DNA methylation of RUNX3 in 13 papillary thyroid cancer tissues and four thyroid cancer cell lines. Additionally, using reverse transcriptase-polymerase chain reaction, we analyzed RUNX3 gene expression in several thyroid cancer cell lines after treating with the demethylating agent 5-aza-2'-deoxycytidine (DAC). RESULTS: RUNX3 was hypermethylated in many thyroid cancer cell lines and in 10 of the 12 papillary thyroid cancer tissues. Treatment with DAC increased the expression of RUNX3 in some thyroid cancer cell lines. CONCLUSIONS: We suggest that RUNX3 is associated with thyroid carcinogenesis, and RUNX3 methylation is a potentially useful diagnostic marker for papillary thyroid cancer.

PURPOSE: For conservative treatment of shaft fractures, the butterfly fragments that were somewhat larger in the closed intra-medullary (IM) nailing. The results of treatment were monitored using radiography separately for the weight-bearing femur and non-weight-bearing humerus. MATERIALS AND METHODS: 27 from Group I and 31 from Group II. In the two groups, the displacement and angulation changes in the fragments, and the degree of improvement of these two factors, were compared using follow-up radiography. RESULTS: The mean angulation of fragments in Groups I and II were 9.2degrees and 9.6degrees, and the mean degree of displacement of the fragments in Groups I and II were 16.7 mm and 21.2 mm, respectively. Follow-up radiography showed that the above factors improved in both groups. The degree of displacement was significantly lower in the normal cases than in the complicated cases (p=0.001). CONCLUSION: Displacement and angulation gradually improved in both groups. It was found that the degree of displacement after the initial reduction is more important than the influence of anatomical position or weight bearing. This indicates that care should be taken when inserting IM nails to prevent displacement or angulation.

PURPOSE: To elucidate a potential association between Helicobacter pylori (HP) infection and iron-deficiency anemia (IDA) in infants and children in terms of the other factors related to iron utilization and storage although the association of ferritin was previously studied. METHODS: We evaluated 135 infants (aged 6-24 months) admitted at Gyeongsang National University Hospital from 2000 to 2006. Western blot assays using the HP CagA antigen (120 kD) were conducted to identify infections. The concentrations of six parameters were measured: hemoglobin (Hb), serum ferritin, soluble serum transferrin receptors, interleukin-6, prohepcidin, and C-reactive protein. In addition, the infants were classified into IDA, anemia from inflammation (AI), unclassified anemia (UCA), and normal groups on the basis of Hb and ferritin concentrations. RESULTS: In the IDA group (n=20), seven infants were infected with HP, with the other infants showing no evidence of infection. The mean Hb levels in the IDA group were significantly lower in HP-infected infants than those uninfected (7.1 vs. 8.2 g/dL, respectively); the mean ferritin levels were also significantly lower in the infected infants (3.2 vs. 6.8 microgram/L). The other four parameters did not differ significantly among the IDA infants. No correlations were found between the six parameters and HP infection status in the other groups. CONCLUSION: There were no significant differences in the HP infection rates among the study groups. However, in the IDA group, the HP-infected infants had significantly lower serum ferritin and Hb levels than the HP-negative infants (P<0.05).

PURPOSE: The concentration of soluble transferrin receptor (sTfR) is estimated as an iron parameter to evaluate erythropoiesis and iron status. The aim of our study is to evaluate the correlation between sTfR concentration and inflammatory parameters and to distinguish iron deficiency anemia from anemia of inflammation. METHODS: One hundred and forty-four infants younger than two years of age who visited Gyeongsang University Hospital for 7 years from 2000 to 2006 were enrolled. Patients who had hemoglobin (Hb) <11 g/dL and ferritin <12 mg/L were excluded. Routine hematologic lab, serum ferritin, sTfR, and inflammatory markers [C-reactive protein(CRP), interleukin-6(IL-6), and absolute neutrophil count (ANC)] were investigated. RESULTS: In all patients, the sTfR concentration showed a correlation with Hb, ferritin, MCV, and ANC, but not with CRP and IL-6. In multiple regression models, positive correlations were found between sTfR concentration and IL-6 (r=0.078, P=0.043), and negative correlations were found between sTfR concentration and ANC (r=-0.117, P=0.033) and MCV (r=-0.027, P=0.009). CONCLUSION: sTfR concentration was influenced by inflammatory parameters. Therefore, sTfR does not appear to be a useful parameter for discriminating between iron deficiency anemia and anemia of inflammation in infants.

BACKGROUND: Due to the irreversible nature of chronic obstructive pulmonary disease (COPD), the treatment aim in patients with COPD is not to cure but to reduce the symptoms, increase lung function, and improve the quality of life. It has been suggested that depression is a common emotional disturbance in patients with COPD who are faced with a major physical impairment and embarrassing symptoms. This study evaluated the prevalence and risk factors of depression in patients with chronic obstructive pulmonary disease. METHODS: A total of 59 patients with a registered diagnosis of chronic obstructive pulmonary disease were selected. Depression was assessed using the Centers for Epidemiologic Studies Depression (CES-D) scale. The quality of life was assessed using the Korean version of the St. George's Respiratory Questionnaire. RESULTS: The prevalence of depression was 17.0%. In the correlation model, the interaction of the FEV1% over predicted value and SGRQ score(symptom, activity, impact, overall score) was statistically significant. The interaction of the FEV1% over predicted value and depression scale(CES-D) was also statistically significant. There was a positive correlation between the SGRQ scores(symptom, activity, impact, overall score) and the depression scale. CONCLUSION: The prevalence of depression in patients with chronic obstructive pulmonary disease is relatively high. The pulmonary function and the living standards were found to be significant risk factors for depression.
