Evaluation of GLUT1, IGF-2, VEGF, FGF 1, and angiopoietin 2 in infantile hemangioma.

INTRODUCTION: Infantile hemangioma (IH) is a common vascular tumor in children. It is reported that IHs are associated with immunochemical markers such as vascular endothelial growth factor (VEGF)-A, glucose transporter isoform 1 (GLUT1), and insulin-like growth factor-2 (IGF-2). MATERIAL AND METHODS: This cross-sectional study focused on pediatric patients with IH. A total of 46 patients (mean age 14.2±21.9 months) with IH and 45 healthy controls (mean age 21.8±15.08 months) were enrolled. Demographic data, clinical findings, and laboratory parameters were recorded. Blood samples were collected. Serum GLUT1, IGF-2, VEGF-A, fibroblast growth factor 1 (FGF1), and angiopoietin 2 levels were assessed by enzyme-linked immunosorbent assay. RESULTS: Serum GLUT1, IGF-2, and VEGF-A levels were significantly higher in patients with IH than in healthy controls (8.80±4.07pg/mL vs. 5.66±4.34pg/mL, 281.10±84.12pg/mL vs. 234.19±75.38pg/mL, 1196.99±389.34pg/mL vs. 996.99±349.16pg/mL, respectively, p=0.026, p=0.030, and p=0.036). Serum GLUT1, IGF-2, and VEGF-A levels in patients with complicated hemangioma were significantly higher than in healthy controls (9.69±3.94pg/mL vs. 5.66±4.34pg/mL, 289.94±83.18pg/mL vs. 234.19±75.38pg/mL, 1276.22±388.24pg/mL vs. 996.99±349.16pg/mL, respectively, p=0.017, p=0.022, and p=0.011). Serum GLUT1, IGF-2, and VEGF-A levels in patients with hemangioma receiving propranolol treatment were significantly higher than in healthy controls. Serum FGF1 levels were higher in patients with IH, complicated hemangioma, and hemangioma receiving propranolol treatment than in healthy controls but the difference was not statistically significantly. CONCLUSION: Serum GLUT1, IGF-2, and VEGF-A levels were positively correlated with disease severity in patients with hemangioma, for example, in complicated hemangioma and hemangioma requiring propranolol treatment. However, further research on larger and different age subgroups is warranted to assess these markers.

Ketogenic diet experience at Ondokuz Mayis University.

BACKGROUND AND OBJECTIVES: The ketogenic diet (KD) is a special diet that is rich in fat, and poor in protein and carbohydrates. KD is the first-line treatment for some metabolic disorders, and is also used in resistant epilepsy, autism, cancer, Parkinson, Alzheimer's diseases, and stroke. The KD team consists of a doctor (child neurologist), nurse, and dietician. After diet adjustment, family training, metabolic tests, consultations, material supply, the initial and follow-up stages are performed by this team. METHOD: Retrospective data analyses of patients followed at ketogenic diet outpatient clinic were made. RESULTS: Fourteen patients (6F, 8M) continued their KD treatment, and nine (4F, 5M) of them stopped the treatment. KD treatment duration for those who continued KD was between 1 and 24 months (mean 7.1, median 4), and KD duration of those who left was between 0.5 and 12 months (mean 5, median 5). Three patients became seizure-free, seven patients had ≥ 50% reduction in their seizures, and four patients had no change in seizure. Anti-epileptic drugs could be reduced in five patients. Improvement in perception and social behaviour of the children was expressed by the families. Although one of the patients was seizure-free and the others had 75% decrease in seizures, they left KD due to frequent infection and family desire. The other seven patients who left KD had no changes in their seizures, but four of them continued KD in less than 2 months, and two of them only for 15 days. Weight loss, family problems, infection, and financial concerns were the reasons for them leaving. CONCLUSION: Today, although the approach is changing, KD still comes to mind for the most resistant, troubled patients. Stopping the patients' seizures, opening their perceptions, and reducing the medications are satisfactory results. We wanted to share our small group of patients and their results in the hope of expanding the ketogenic diet.

An Unusual Presentation of T-Cell Lymphoblastic Lymphoma with Isolated Renal Involvement.

The clinical presentation of Non-Hodgkin lymphoma (NHL) is frequently associated with the involvement of the abdomen and mediastinal lymphadenopathies, but rarely the kidney, ovaries, and testicles. Here, we report a rare case of T-cell lymphoblastic lymphoma (T-LBL) presenting with bilateral nephromegaly without acute renal failure (ARF) as the first manifestation. A 30-month-old boy was admitted to the department of pediatric nephrology exhibiting abdominal distension. Physical examination revealed bilateral renal palpation up to the inguinal region. Elevated lactate dehydrogenase (LDH) levels were detected in his blood. Bilateral diffuse enlarged kidneys with increased hypoechogenicity were found on abdominal ultrasonography. In the next step, contrast-enhanced computed tomography showed diffusely enlarged kidneys, which were compressing the intestinal bowels and midline structures. Renal biopsy demonstrated precursor T-LBL. We wish to report our patient with renal T-LBL presenting with diffuse renal enlargement, which has rarely been reported in the literature.

Harmony in Life Scale - Turkish version: studies of validity and reliability

This article presents the adaptation and psychometric evaluation of the Turkish version of Harmony in Life Scale (Turkish-HiL). The present paper investigates (study 1; N 1 = 253) confirmatory factor analysis, measurement invariance; (study 2; N 2 = 231) concurrent validity; (study 3; N 3 = 260) convergent and known-group validities; (study 4; N t − t = 50) test-retest, Cronbach alpha, and composite reliabilities of the Turkish-HiL. In study 1, based on a confirmatory factor analysis, results confirmed that unidimensional-factor structure. The results suggested that the model demonstrated a configural and metric invariance across the gender groups. In study 2, Turkish-HiL significantly correlated with measures of satisfaction with life, subjective happiness, positive affect, and negative affect. In study 3, Turkish-HiL was predicted positively by flourishing, conversely, negatively predicted by depression, anxiety, and stress. Finally, in study 4, alpha, composite and test-retest reliabilities are acceptable. Overall, the scale presented here may prove useful for satisfactorily assessing, in Turkish, the harmony in life of the university students. (AU)

Lack of influence of pregnancy on the prognosis of survivors of thyroid cancer.

OBJECTIVE: The aim of this study is to investigate the influence of pregnancy on prognosis of thyroid cancer. METHODS: A total of 72 patients aged between 15-45 years who underwent total or subtotal thyroidectomy and subsequently radioablation were followed up under suppression. Individuals who had term pregnancies after diagnosis of cancer (group 1, n: 36) and who were non-pregnant (group 2, n:36) were included in the study. Both groups were compared in terms of scintigraphic relapse and metastasis, ultrasonographic relapse, stage change of lympadenopathy at the beginning and at the end of the study. RESULTS: Relapse was detected in 4 out of 36 pregnant patients (11.1%) and in 5 out of 36 non-pregnant patients (13.9%) with no significant difference between groups (p=1.00). Pathologic lymphadenopathy was detected in 2 out of 36 pregnant patients (5.6%) and in 2 out of 36 non-pregnant patients (5.6%) (p=1.00), and metastasis in 3 (8.3%) and in 1 (2.8%), respectively (p=0.61). While stage change was detected in only one pregnant patient (2.8%), and none of the non-pregnant again there was no significant difference (p=1.00). CONCLUSIONS: We conclude that pregnancy does not have an influence on prognosis of thyroid cancer.

Light-emitting iridium(III) and ruthenium(II) polypyridyl complexes containing quadruple hydrogen-bonding moieties.

A novel compound containing both a 2,2'-bipyridine as well as a 2-ureido-4[1H]-ureidopyrimidinone supramolecular moiety (3) has been synthesised and fully characterized by 1H-NMR, MALDI-TOFMS, UV-vis and IR spectroscopy. Subsequent coordination to iridium and ruthenium polypyridyl precursors allowed the formation of iridium(III) and ruthenium(II) polypyridyl dimers (5 and 7) assembled via quadruple hydrogen-bonding as well as metal coordination interactions. The syntheses and complete characterization of these materials by means of two-dimensional NMR techniques (1H-1H COSY and 1H-1H DOSY) as well as IR and MALDI-TOFMS are described in detail. Comparative studies of the optical properties of the luminescent model complexes (5' and '7) and the dimer species (5 and 7) are also illustrated. In addition, good processability of the materials has been demonstrated by inkjet printing leading to thin films revealing their potential for light-emitting devices.
