RESUMO

PURPOSE: Current fracture risk assessment options in men call for improved evaluation strategies. Recent research directed towards non-classic bone mass determinants have often yielded scarce and conflicting results. We aimed at investigating the impact of novel potential bone mass regulators together with classic determinants of bone status in healthy young and middle-aged men. METHODS: Anthropometric measurements, all-site bone mineral density (BMD) and body composition parameters assessed by dual-energy X-ray absorptiometry and also serum concentrations of (1) the adipokines leptin and resistin, (2) vitamin D and parathormone (PTH), (3) sex hormone binding globulin (SHBG), total testosterone and estradiol (free testosterone was also calculated) and (4) C-terminal telopeptide of type I collagen (CTx) were obtained from 30 apparently healthy male volunteers aged 20-65 years enrolled in this cross-sectional study. RESULTS: Only lean mass (LM) and total estradiol independently predicted BMD in men in multiple regression analysis, together explaining 49% (p ≤ 0.001) of whole-body BMD variance. Hierarchical regression analysis with whole-body BMD as outcome variable demonstrated that the body mass index (BMI) beta coefficient became nonsignificant when LM was added to the model. Adipokines, fat parameters, testosterone (total and free), SHBG, PTH and vitamin D were not independently associated with BMD or CTx. CONCLUSIONS: The present study shows that LM and sex hormones-namely estradiol-are the main determinants of bone mass in young and middle-aged men. The effects of BMI upon BMD seem to be largely mediated by LM. Lifestyle interventions should focus on preserving LM in men for improved bone outcomes.

RESUMO

Background and aim: The goals of bariatric surgery are to improve the quality of life by lowering body mass index (BMI) but also to treat obesity comorbidities. The aim of our study was to evaluate the impact of laparoscopic sleeve gastrectomy (LSG) on metabolic parameters. Methods: 85 obese patients treated by bariatric surgery LSG procedure were included in the study. Basal, 6 and 12 months after surgery serum glucose levels and lipid fractions were measured. Metabolic syndrome criteria according to IDF 2006 were evaluated at baseline and after bariatric surgery. Results: Our group included 61.2 % female patients, the mean age was 40.2 ±10.2 years and the metabolic syndrome criteria at baseline were confirmed in 69.4% of the study group. At twelve months after the intervention, the mean excess weight loss (%EWL) was 72%, with age and BMI subgroups variations. We found significant improvements of serum concentrations for triglycerides (P-value = 0.001, decreased by 30%), HDL-cholesterol (P-value = 0.017, increased by 26%), total cholesterol (P-value = 0.043, decreased by 12%) and glucose (P-value = 0.007, decreased by 12%). Conclusions: The positive effect of bariatric surgery was confirmed for lipid fractions and fasting glucose levels, also the metabolic syndrome prevalence was significantly reduced, all these changes contribute to lower cardiovascular risk together with significant weight loss.

RESUMO

There is a wide variety of local therapeutical methods for extensive burns. This article aims to be a general overview of the most common methods used in the local treatment for extensive burns, both in our clinic and globally. Clinical examples are shown from our clinic; cases of the last 8 years. None of the less there is no such thing as the "perfect method of treatment" but a thin balance between the clinical experience of plastic surgeons, every case particularities and specified characteristics, meaning advantages, disadvantages and limited indications of local topics or methods of skin covering.

RESUMO

Squamous cell carcinoma is a very rare type of urachal malignancy, only a few cases being reported in the medical literature. We present the case of a 49-year-old male patient diagnosed with infected squamous cell urachal carcinoma with multiple pulmonary metastases, after complaints of lower abdominal pain, abdominal mass and fever, without respiratory symptoms. The abdominal ultrasonography and the CT scan revealed a tumoral mass in the lower abdomen in contact with the abdominal wall and the urinary bladder dome, displacing the small bowel. Pulmonary nodular lesions were described in the left lobe pyramid. The intraoperative diagnosis was necrotic urachal tumor with urinary bladder dome invasion and suspected pulmonary metastases, and tumor ablation with bladder dome resection and suture of the bladder were performed. The histopathological result was poorly differentiated squamous cell carcinoma (G3), with negative resection margins. The patient recovered well after surgery, but the prognosis is very poor due to the metastatic stage in which the tumor was diagnosed, no standard chemotherapy regimen for the treatment of metastatic urachal carcinoma being known as effective until now.

RESUMO

UNLABELLED: Research on the relationship between iodine exposure and thyroid cancer risk is limited and the findings are inconclusive. OBJECTIVES: Given this molecular data on iodine we decided to evaluate the changes of incidence and histology of thyroid cancer in the North-Eastern region of Romania (Moldavia) after the government decision from 2004 that introduced the universal iodination of alimentary salt. After this decision values of urinary iodine increased from 50 microg/L (2001-2002) to 117 microg/L (2006 -2008). MATERIAL AND METHODS: We compared the incidence and the histology of thyroid cancer in residents living in an area known as a mild endemic goiter region (Moldavia-Romania) between 2001-2004 with the incidence and the histology of thyroid cancer between 2005-2008 in the same region after the introduction of universal iodization of alimentary salt. RESULTS: The number of papillary cancers increased from 125 cases (2001-2004) to 276 cases (2005-2008). The number of follicular cancer decreased from 52 cases (2001-2004) to 27 cases (2005-2008). The ratio between papillary and follicular cancers increased from 4.80 / 1 (2001-2004) at 10.61 / 1 (2005-2008). The number of medullar thyroid carcinoma increased from six cases (2001-2004) to 24 cases (2005-2008). Thyroid anaplastic carcinomas number increased from 7 cases (2001-2004) to 12 cases (2005-2008). The total number of thyroid cancer has increased dramatically after the introduction of universal iodination of alimentary salt with 178% compared to 2001-2004 (from 190 cases in 2001-2004 to 339 cases in 2005-2008), despite the fact that the number thyroidectomies decreased from 1734 (2001-2004) to 1449 (2005-2008). CONCLUSION: After the introduction the universal iodination of alimentary salt starting from 2004 the total number of thyroid cancers increased comparative with the period before universal iodination of alimentary salt.

RESUMO

INTRODUCTION: Initially considered experimental, liver transplantation (LT) has become the treatment of choice for the patients with end-stage liver diseases. MATERIAL AND METHODS: Between April 2000 and October 2009, 200 LTs (10 reLTs) were performed in 190 patients, this study being retrospective. There were transplanted 110 men and 80 women, 159 adults and 31 children with the age between 1 and 64 years old (mean age--39.9). The main indication in the adult group was represented by viral cirrhosis, while the pediatric series the etiology was mainly glycogenosis and biliary atresia. There were performed 143 whole graft LTs, 46 living donor LTs, 6 split LTs, 4 reduced LTs and one domino LT RESULTS: The postoperative survival was 90% (170 patients). The patient and graft one-year and five-year survivals were 76.9%, 73.6% and 71%, 68.2%, respectively. The early complications occurred in 127 patients (67%). The late complications were recorded in 71 patients (37.3%). The intraoperative and early postoperative mortality rate was 9.5% (18 patients). CONCLUSIONS: The Romanian liver transplantation program from Fundeni includes all types of current surgical techniques and the results are comparable with those from other international centers.

RESUMO

The reading process takes place in a neuronal network comprising the inferior frontal, posterior dorsal and posterior ventral brain areas. It is suggested that developmental dyslexia is caused by a disruption of the two posterior network areas. What remains debatable is whether these areas are affected in their functionality or whether the neuronal networking (connectivity) of these areas suffer from a disturbed information transfer. Thus, it is of major interest to investigate the time flow of the directed information transfer (time variant connectivity) within the neuronal reading network of dyslexic subjects. We investigated adolescents with dyslexia and normal-reading controls with functional magnetic resonance imaging and electroencephalography (EEG) with a paradigm addressing basic visual, orthographic and phonological processing. EEG data were analyzed with the time variant Granger causality index (tvGCI) to investigate the temporal order of the directed information transfer (time variant causal connectivity: which network node passes when information to which network node) during reading in dyslexic readers. Results show that the reading network of dyslexic readers comprises the same brain areas as identified in normal-reading subjects. The tvGCI analysis of the network profiles of dyslexic readers indicates that dyslexics show a difference in timing and localization of connectivity within this reading network compared to normal readers. Dyslexic readers use right hemisphere language areas to counterbalance posterior left hemisphere processing deficits. The compensatory involvement of homologue right hemisphere brain areas for the reading process may be the neurobiological background for the significantly longer reading times by dyslexics.

RESUMO

Time-variant Granger Causality Index (tvGCI) was applied to simulated and measured BOLD signals to investigate the reliability of time-variant analysis approaches for the identification of directed interrelations between brain areas on the basis of fMRI data. Single-shot fMRI data of a single image slice with short repetition times (200 ms, 16000 frames/subject, 64x64 voxels) were acquired from 5 healthy subjects during an externally-driven, self-paced finger-tapping paradigm (57-59 single taps for each subject). BOLD signals were derived from the pre-supplementary motor area (preSMA), the supplementary motor area (SMA), and the primary motor cortex (M1). The simulations were carried out by means of a Dynamic Causal Modelling (DCM) approach. The tvGCI as well as time-variant Partial Directed Coherence (tvPDC) were used to identify the modelled connectivity network (connectivity structure - CS - of the DCM). Different CSs were applied by using dynamic systems (Generalized Dynamic Neural Network - GDNN) and trivariate autoregressive (AR) processes. The influence of the low-pass characteristics of the simulated hemodynamic response (Balloon model) and of the measuring noise was tested. Additionally, our modelling strategy considered "spontaneous" BOLD fluctuations before, during, and after the appearance of the event-related BOLD component. Couplings which were extracted from the simulated signals were statistically evaluated (tvGCI for shuffled data, confidence tubes for tvGCI courses). We demonstrate that connections of our CS models can be correctly identified during the event-related BOLD component and with signal-to-noise-ratios corresponding to those of the measured data. The results based on simulations can be used to examine the reliability of connectivity identification based on BOLD signals by means of time-variant as well as time-invariant connectivity measures and enable a better interpretation of the analysis results using fMRI data. A readiness-BOLD response was only detected in one subject. However, in two subjects a strong time-variant connection (tvGCI) from preSMA to SMA was observed 3 s before the tapping was executed. This connection was accompanied by a weaker rise of the tvGCI from preSMA to M1. These preceding interrelations were confirmed in the other subjects by the dynamics of tvGCI courses. Based on the results of tvGCI analysis, the time-evolution of an individual connectivity network is shown for each subject.

RESUMO

OBJECTIVES: The main objective is to show current topics and future trends in the field of medical signal processing which are derived from current research concepts. Signal processing as an integrative concept within the scope of medical informatics is demonstrated. METHODS: For all examples time-variant multivariate autoregressive models were used. Based on this modeling, the concept of Granger causality in terms of the time-variant Granger causality index and the time-variant partial directed coherence was realized to investigate directed information transfer between different brain regions. RESULTS: Signal informatics encompasses several diverse domains including: processing steps, methodologies, levels and subject fields, and applications. Five trends can be recognized and in order to illustrate these trends, three analysis strategies derived from current neuroscientific studies are presented. These examples comprise high-dimensional fMRI and EEG data. In the first example, the quantification of time-variant-directed information transfer between activated brain regions on the basis of fast-fMRI data is introduced and discussed. The second example deals with the investigation of differences in word processing between dyslexic and normal reading children. Different dynamic neural networks of the directed information transfer are identified on the basis of event-related potentials. The third example shows time-variant cortical connectivity networks derived from a source model. CONCLUSIONS: These examples strongly emphasize the integrative nature of signal informatics, encompassing processing steps, methodologies, levels and subject fields, and applications.

RESUMO

Elemental carbon represents a fundamental building block of matter and the possibility of ferromagnetic order in carbon has attracted widespread attention. However, the origin of magnetic order in such a light element is only poorly understood and has puzzled researchers. We present a spectromicroscopy study at room temperature of proton irradiated metal-free carbon using the elemental and chemical specificity of x-ray magnetic circular dichroism. We demonstrate that the magnetic order in the investigated system originates only from the carbon pi-electron system.

RESUMO

The antimicrobial and antifungal activity of some 4,4'-bipyridine derivatives were studied. The diffusimetric gelose surface diffusion method with stainless steel cylinders was used to study bacteria and Sabouraud fields for Candida albicans. Comparative analysis of the results led to the following conclusions. Diquaternary salts of 4,4'-bipyridinium possess a remarkable antimicrobial and antifungal activity. The influence of R1 and R2 substitutes in the para or meta position of the benzoylic radical affects selectivity but does not greatly influence activity.

RESUMO

Nicorandil (N-(2-hydroxy-ethyl)-nicotine amide nitrate), drug recently introduced in therapy, is used as a vasodilator through potassium channel activation. Nicorandil is obtained by treating nicotinic acid chloride hydrochloride with nitro-oxy-ethyl-amine nitrate in an organic solvent. The authors suggest a method that uses ethyl nicotinate as raw material. Thus, the drug can be obtained from indigenous raw materials, at a lower price than the imported ones, with a high purity and a good yield.

RESUMO

Levothyroxine (LT4) treatment in benign thyroid nodules is a controversial management. The favorable response varies between 10-60%, being, in some studies, comparable between treated and untreated groups. The aim of this study was to evaluate the response of uninodular goiter at the LT4 treatment, in comparison with untreated patients. The study group (S) included 53 patients diagnosed with nodular goiter, treated with LT4 for 1 year. 26 patients with nodular goiter, age and sex-matched, untreated, constituted the control group (C). All patients were from a minor iodine deficient area. The including criteria were euthyroidism, single nodule, solid (ultrasonography), cold (Scintigraphy), and benign (FNAB). After 1 year mean nodular volume had a significant decrement in both groups, higher in group S (35%: from 7.8 to 5.2 mL, p = 0.0098) than in group C (25%: from 8.4 to 5.9 mL, p = 0.026). Linear regression showed a slight correlation between the nodular decrement and the initial volume (r = 0.23): the responders percentage was higher in nodules with a volume < 5 ml than in those with volume > 5 ml (51.5% vs o 19.6%, p < 0.0001). The evolution of treated nodules seamed to be better than of the untreated ones, but the differences were only slightly significant. We believe that the evolution of thyroid nodules under LT4 treatment can be influenced by the iodine supply, since in most of the studies from minor iodine deficiency regions (Europe, South America) the response is better than in regions with sufficient iodine supply (North America). Knowing the potential side effects of LT4 therapy, this kind of management of benign thyroid nodules should be reserved to selected cases.

RESUMO

Ultrasonography is a useful tool in diagnosing and monitoring thyroid pathology. The aim of this study was to evaluate the value of thyroid ultrasonography in the follow-up of subacute thyroiditis (SAT). The study group included 48 subjects with clinical and biological diagnosis of subacute thyroiditis. All patients were evaluated by ultrasonography and followed-up for a mean period of 12 months. The evaluation protocol included biological data (TSH, T4, erythrocyte sedimentation rate--ESR) and ultrasonography, performed at 1, 2, 3, 6, and 12 months. Initially, all patients had an enlarged thyroid volume (median = 30.5 ml, range 23-90) and a low echogenicity, with an inhomogeneous aspect in 54.1% cases. After a mean period of 3 months thyroid volume had a significant reduction (median volume = 20.2 ml, range 7-36, p < 0.0001). Echogenicity was also significantly improved, with a decrement, on a semi-quantitative scale of 4 degrees (1 = normal, 4 = intense hypoechogenicity), from 3.25 to 2.48 (p < 0.0001). Almost half of the patients (45.8%) presented persistent (although slighter) hypoechoic/inhomogeneous pattern. Ultrasonographic abnormalities were not correlated with the intensity of the inflammatory syndrome and/or the thyroid status. Recurrence appeared in 10 (20.8%) patients. All patients presented a new thyroid enlargement (from a median = 16.1 ml to 31.5 ml, p = 0.056) and an extension of hypoechoic regions. The risk of recurrence could not be correlated with thyroid function, inflammatory syndrome or ultrasonographic aspect. There were not significant differences between the subgroups of patients with and without recurrence concerning the initial thyroid volume (p = 0.889), echogenicity (p = 0.735), TSH (p = 0.321) or ESR (p = 0.1332). Thyroid ultrasonography is useful not only for the initial diagnosis but also for the follow-up of patients with subacute thyroiditis. Remission and recurrence can be appreciated and monitored by the ultrasonographic pattern of the thyroid.

RESUMO

Prolactinoma is a frequent endocrine cause of infertility in both man and women. The aim of this study was to evaluate female fertility in association with hyperprolactinemia. The study is a retrospective one, based on the cases monitored in the Endocrinology Department of Iasi. From the 113 cases of prolactinoma in women we have selected 83 women aged between 18-45 years (fertile age). The diagnosis was suspected on clinical bases: endocrine (amenorrhea-galactorrhea, associated or isolated, spaniomenorrhea, infertility), and tumoral (headache, visual disturbances) syndromes and confirmed by biological (PRL dosage) and morphological (pituitary CT) tests. We classified the found associations between prolactinoma and fertility in: no correlation (previous pregnancies with no desire for another child--76 patients = 75.2%); prolactinoma diagnosed immediately after a pregnancy by persistency of galactorrhea, lack of menses reapparition, headache (16 cases = 15.8%); prolactinoma diagnosed before pregnancy, which was obtained thanks to the hyperprolactinemia treatment (9 patients = 8.9%). All 9 patients of the last group were in remission at the moment of pregnancy apparition and had a normal pregnancy, giving birth to normal children. Infertility associated with prolactinoma is reversible with treatment. Lowering of prolactin levels to normal is often necessary to permit ovulation. Bromocriptine used by pregnant women appears to be safe for the developing fetus, at least in our study where the treatment was interrupted in most cases in the first trimester of pregnancy.
