RESUMO

PURPOSE: It is known that children with diabetes have more severe vitamin D deficiency than healthy children. This study aimed to investigate serum vitamin D status and analyze the relationships between serum vitamin D levels and clinical parameters in children with diabetes. METHODS: We checked serum vitamin D levels of children with diabetes aged below 18 years who were treated at our Department of Pediatrics between December 2011 and February 2012 (winter) as well as between June 2012 and August 2012 (summer). We retrospectively analyzed relationships between their serum vitamin D levels and clinical parameters. RESULTS: The serum 25-hydroxyvitamin D level in children with diabetes during winter was markedly lower than during summer (10.8±5.1 ng/mL vs. 17.6±5.6 ng/mL); vitamin D deficiency was more prevalent during winter (95% vs. 62%). However, there was no difference between children with diabetes and healthy children. In children with type I diabetes mellitus, among all the clinical parameters, age had the greatest negative correlation with serum vitamin D level. CONCLUSION: In children with diabetes, serum vitamin D levels showed marked seasonal variation. However, no clear relationship was identified between vitamin D deficiency and diabetes. This was because the control group had an equally high vitamin D deficiency rate. Additional studies including other clinical parameters after vitamin D supplementation in children with diabetes should be considered.

RESUMO

Situs inversus of the abdominal organs in the presence of normally placed heart on the left side of the thorax is known as situs inversus with isolated levocardia. This rare condition is commonly associated with severe congenital defects of the heart. We report a case of situs inversus with levocardia in a 19-year-old asymptomatic male patient with completely normal heart on the left chest. Spiral computed tomography of the thorax and abdomen and echocardiographic studies revealed situs inversus of abdominal organs, normal heart (levocardia), mirrored left lungs, a midline liver, a left-sided inferior vena cava connecting to the right atrium, multiple splenic masses in the abdominal right upper quadrant, and aneurysmal dilatation of a splenic artery.

RESUMO

In this paper, we describe 72-year-old female patient without evidence of malignant disease presented with significantly elevated serum carbohydrate antigen (CA) 19-9 levels by respiratory infections. She was diagnosed with respiratory infections due to Mycobacterium avium complex and Pseudomonas aeruginosa. The serum CA 19-9 levels remarkably increased (1,453-5,300 U/mL; reference range, <37 U/mL) by respiratory infection and abruptly decreased (357-534 U/mL) whenever infection was controlled by specific treatments. This case suggests that serum CA 19-9 levels may be used as a diagnostic marker to indicate new or resistant infections to previous antibiotics in chronic lung diseases without significant changes in chest X-ray findings.

RESUMO

Identification of molecular alterations in biological fluids has been proposed as a powerful tool for cancer diagnosis. The purpose of this study was to identify cells that carry chromosomal alterations indicative of malignancy-specifically, gains in the loci 5p15.2 (D5S23, D5S721), 6p11 approximately q11, 7p12 (EGFR), and 8q24.12 approximately q24.13 (MYC)-for the detection of lung cancer using induced sputum. The overall sensitivity of the multicolor fluorescence in situ hybridization (FISH) assay from 52 lung cancer patients was 71% and the specificity was 100% (15 of 15). The most frequently detected gains were at 7p12 (EGFR) in 17 of 24 completely resectable early-stage (II+IIIA) non-small cell lung cancers (NSCLC) (71%). There was a statistically significant increase in the proportion of cases with gains of EGFR in squamous cell carcinomas (SCC), compared with adenocarcinomas (AC) (82 vs. 43%, respectively; P = 0.017), and a higher average EGFR gene copy number in the SCCs than in the ACs (5.04 vs. 3.78, respectively; P = 0.013) in 41 NSCLCs. Conversely, a gain at the 6p11 approximately q11 and 8q24.12 approximately q24.13 (MYC) regions appears to have a higher frequency of gain in the ACs (71 and 86%, respectively) than in the SCCs (48 and 56%, respectively). The results of this study showed the potential utility of the LAVysion FISH assay for the detection of lung cancer by a noninvasive technique based on the analysis of genetic alterations of induced sputum. Defining abnormalities in sputum specimens as FISH aneusomy may be a possible diagnostic method for the early detection of lung cancer in screening of high-risk populations and monitoring for recurrence.

RESUMO

Detection of genetic alterations could provide a tool as an adjuvant for the diagnosis of non-small cell lung cancer (NSCLC) and to define patients at risk for early relapse. In this study, a multi-target fluorescence in situ hybridization (FISH) assay was conducted to investigate the correlation between the alterations of chromosomes, including 5p15.2, 6p11.1-q11, 7p12, and 8q24.12-q24.13 (LaVysion Test), and clinicopathological variables, and to clarify the potential of the multi-target FISH assay in 37 NSCLC. The most notable finding was the higher frequency of a gain in chromosome 5p15.2 in early-stage (I+IIa) lung cancers. The frequency of the gain was 81.3% (16/22) in stage I tumors. The frequencies of gains in 6p11.1-q11 and 8q24.12-q24.13 were 61.5% (8/13) and 84.6% (11/13) in stage IIIa cancers, as compared with lower frequencies in stage I tumors at 25.0% and 31.3%, respectively. There was also a significant difference in the histological type. Our results suggest that a gain in 6p11.1-q11 and 8q24.12-q24.13 plays an important role in tumor progression and is associated with histological differentiation. On the other hand, gene amplification in the 5p region was one of the most consistent alterations in early-stage lung cancer, and thus a series of genes in the critical 5p15.2 region might potentially associated with the development of lung cancer.
