Prevalence and Distribution of Cervical Dentin Hypersensitivity in a Greek Population

Background and aims. The aim of the present study was to estimate the prevalence of dentin hypersensitivity in an adult population in Greece. Materials and methods. Eight hundred patients participated in the present study, including 380 males and 420 females with an age range of 18‒64 years. All the subjects answered questions regarding gender, age, educational level, teeth affected and any factor that initiated dentin hypersensitivity. This was followed by a clinical examination involving assessment of sen-sitive teeth per patient and any buccal gingival recession associated with sensitive teeth. Data were analyzed using descriptive statistics and chi-squared test. Results. Our findings showed that 13.5% of the patients had dentine hypersensitivity. Prevalence of hypersensitivity in fe-males (15%) was not significantly higher (p=0.465) than males (11.8%). The mean number of sensitive teeth per patient showed a peak in the 35‒44 age group and then reduced slowly in the older and younger cohorts. The teeth most commonly affected by dentin hypersensitivity were the first and second premolars of both jaws followed by the canines of both jaws. The majority (82.5%) of sensitive teeth had at least 1-3 mm of gingival recession. Pain-initiating stimuli frequently observed were the consumption of cold drinks followed by consumption of hot drinks and tooth-brushing. A statistically significant difference was recorded between dentin hypersensitivity and educational level (p=0.045). Conclusions. The prevalence of dentin hypersensitivity in an adult population sample in Greece was 13.5% and the mean number of sensitive teeth per patient was observed to increase with age.
DynamFluid: Development and Validation of a New GUI-Based CFD Tool for the Analysis of Incompressible Non-Isothermal Flows

A computational fluid dynamics software (DynamFluid) based on the application of the finite element method with the characteristic-based-split algorithm is presented and validated. The software is used to numerically integrate the steady and unsteady Navier–Stokes equations for both constant-density and Boussinesq non-isothermal flows. Benchmark two-dimensional computations carried out with DynamFluid show good agreement with previous results reported in the literature. Test cases used for validation include (i) the lid-driven cavity flow, (ii) mixed convection flow in a vertical channel with asymmetric wall temperatures, (iii) unsteady incompressible flow past a circular cylinder, and (iv) steady non-isothermal flow past a circular cylinder with negligible buoyancy effects. The new software is equipped with a graphical user interface that facilitates the definition of the fluid properties, the discretization of the physical domain, the definition of the boundary conditions, and the post-processing of the computed velocity, pressure and temperature fields.
Conversations with long-term heroin users in Amsterdam

Het medisch beeld van heroïne heeft geleid tot een ideologische constructie van ‘verslaving’ waarbij heroïne-gebruikers gezien worden als fysiek afhankelijk van de drug tot schade van hun leefsituatie. In de Westerse maatschappij draagt heroïne een stigma: het botst met belangrijke culturele waarden zoals productiviteit, zelfbeheersing, en een ‘gezond lichaam’. Het is deze verslavingsideologie, gecreëerd en versterkt door beleidsmakers, (para)medici, vertegenwoordigers van volksgezondheid en politici, die heeft vorm gegeven aan het type zorg dat aangeboden wordt aan gebruikers van heroïne. Vanuit het perspectief van de gebruiker krijgen wij echter een geheel ander beeld van het effect van heroïne op gezondheid en welzijn. Uit gesprekken met vijf langdurige gebruikers van heroïne wordt duidelijk dat er een grote diversiteit is in typen van heroïne-gebruikers en dat sommigen van hen in staat zijn met gebruik te stoppen of een normaal leven te leiden met heroïne. Dit artikel pleit voor verandering in het beleid van institutionele en maatschappelijke ondersteuning aan heroïne-gebruikers en voor vermindering van het stigma dat op hen geplakt wordt.
Macrophages and Microglia in Brain Malignancies

Tumour and myeloid cell interactions that occur in the brain are exposed to unique microenvironmental conditions. While tumour outgrowth ultimately has a major impact, the intrinsic properties of the brain initially impose the framework on which subsequent cellular interactions must build. The particularities of the brain are partly anatomical, with strictly controlled traffic of cells and molecules from the blood by virtue of the blood brain barrier (BBB). But they are also due to a unique cellular composition not found outside the nervous system; this includes the neurons and glial cells which have potent immunoregulatory properties. Taken together, these factors have been used to attempt to explain the “immune privilege” of the brain, which is often used to describe low level adaptive immune responses. But in addition immune privilege also impacts on, and is influenced by, the brain myeloid cells which are the subject of this chapter.
Galium spurium AND G . aparine RESISTANCE TO ALS-INHIBITING HERBICIDES IN NORTHERN GREECE Resistência

Knowledge of the level of resistance of weed populations and the herbicides to which they survive is important for recommending suitable advice to farmers and allowing the selection of appropriate management strategies. Wholeplant dose response experiments were carried out to assess the resistance status of eight putative resistant Galium spurium L. populations and one G. aparine L. population, originating from northern Greece. High levels of resistance of both species to the ALS-inhibiting herbicides chlorsulfuron and tribenuron were found, while their susceptible populations were controlled. Three G. spurium (GS) populations showed additional cross-resistance to [florasulam + 2,4-D], whereas the remaining five resistant GS populations were controlled with [tribenuron + mecoprop-p], [florasulam + 2,4-D], and [florasulam + aminopyralid]. Also, [florasulam + fluroxypyr] was very effective against two resistant GS populations tested. DNA sequence alignment of the three GS populations (GS 1, GS 6, and GS 8) with cross-resistance to chlorsulfuron, tribenuron, and florasulam revealed a point mutation at Trp-574 (tryptophan-574), causing amino acid substitution by Leu (leucine). The G. aparine (GA) population showed cross-resistance to chlorsulfuron and tribenuron, but it was controlled with [tribenuron + mecoprop-p], [florasulam + aminopyralid], [florasulam + 2,4-D], and [florasulam + fluroxypyr]. The confirmed cross-resistance of both GS and GA species to chlorsulfuron and tribenuron in northern Greece is the first report of Galium spp. resistance to ALS-inhibiting herbicides in Europe. Finally, all populations (8 GS and 1 GA) that showed resistance to chlorsulfuron and tribenuron were controlled with the mixtures [tribenuron + mecoprop-p] and [florasulam + fluroxypyr].
Effects of Household Use of Biomass Fuel and Kerosene on Birth Weight of Babies in the Philippines

Birth weight is an important indicator of a child’s health status. It is a significant factor of mortality and morbidity. Infants with low birth weight are 40 times more likely to die within the first 28 days of birth than infants with normal birth weight. Moreover, low birth weight infants exhibit a much higher incidence of neurological impairment, gross and fine motor dysfunction and developmental delay. Instead of going down to reduce the incidence of child mortality (which is one of the Millennium Development Goals), the incidence of low birth weight in the Philippines has gone the opposite direction: rising from 20.3% in 2003 to 21.2% in 2008. This paper tackles the very serious issue of birth weight using data from the 2008 National Demographic and Health Survey (NDHS), and focuses on one important risk factor: type of cooking fuel used in the household. Using ordinal logistic regression model, the study establishes that the use of dirty cooking fuel (biomass fuel or kerosene) for daily use of cooking and heating is a significant environmental risk factor of low birth weight. Moreover, the results also show that maternal smoking is significantly associated with the size of the child at birth. Other demographic factors that may be associated with low birth weight are examined as well. Information about the effect cooking fuel on birth weight should lead the government and policymakers to make clean cooking fuel available to Philippine households at a cheap cost.

Prognostic value of selected microscopic criteria in medullary breast cancer

Introduction. WHO defines medullary carcinoma of the breast as a circumscribed neoplasm consisting of poorly- differentiated cells with scant stroma and significant lypmhocytic infiltration. Material and methods. We analyzed 110 patients with medullary breast cancer, who received primary surgical treatment at the Cancer Center in Krakow between the years 1956 and 1988. The clinical presentation of medullary breast cancer was analyzed and the clinical picture and treatment results were compared for typical and atypical variants of medullary breast cancer, aiming at the evaluation of the usefulness of distinguishing between typical and atypical variants. The characteristic immunohistochemical and cytometric features of medullary breast cancer were also studied. Results. In 77 patients the typical variant of medullary breast cancer was diagnosed, and in 33 patients - atypical. When we applied the criteria of Ridolfi et al. in cases with typical variant 10 survival was significantly longer, as compared to the atypical variant; when we used the criteria of Petersen et al. criteria we found no statistically significant differences. ; additionally in the typical variant group 10 the survival rates were almost 10% smaller when compared to the criteria of Ridolfi et al. Univariate analysis of prognostic factors showed significant, unfavorable impact on 10 year disease-free survival rate of: lymph node metastases, atypical medullary breast cancer and (with borderline significance) proliferation index >11 and MIB-1 >70. Age, symptom duration, DNA ploidy, S-phase fraction, expression of p53 gen, c-erb B-2 and vimentine had no significant impact on the treatment results. Multivariate analysis showed that independently significant unfavorable factors were: atypical variant of medullary breast cancer, axillary lymph node metastases, tumor localization other than outer upper quadrant, proliferation index >11. The diagnosis of the typical variant of medullary breast cancer has no significant impact on the choice of treatment, but it has a useful clinical prognostic value.
SEROPREVALENCE OF BRUCELLOSIS IN ANIMALS IN DISTRICT KOHAT NWFP AND COMPARISON OF TWO SEROLOGICAL TESTS

Seroprevalence of brucellosis in 637 cattle and 344 sheep / goats from Government (Militry Dairy Farm Kohat) and private livestock farm (Wahid Jan Dairy Farm Kohat) was carried out by performing Rose Bengal Plate Test (RBPT) and serum agglutination test (SAT) at Veterinary Research and Diagnostic Laboratory Kohat during 5 years (1996-2001). RBPT Positive animals, 17.58% cattle and 32.5% sheep/goats were found seropositive when applied SAT.
A 65-nm Neuromorphic Image Classification Processor With Energy-Efficient Training Through Direct Spike-Only Feedback

Recent advances in neural network (NN) and machine learning algorithms have sparked a wide array of research in specialized hardware, ranging from high-performance NN accelerators for use inside the server systems to energy-efficient edge computing systems. While most of these studies have focused on designing inference engines, implementing the training process of an NN for energy-constrained mobile devices has remained to be a challenge due to the requirement of higher numerical precision. In this article, we aim to build an on-chip learning system that would show highly energy-efficient training for NNs without degradation in the performance for machine learning tasks. To achieve this goal, we adapt and optimize a neuromorphic learning algorithm and propose hardware design techniques to fully exploit the properties of the modifications. We verify that our system achieves energy-efficient training with only 7.5% more energy consumption compared with its highly efficient inference of 236 nJ/image on the handwritten digit [Modified National Institute of Standards and Technology database (MNIST)] images. Moreover, our system achieves 97.83% classification accuracy on the MNIST test data set, which outperforms prior neuromorphic on-chip learning systems and is close to the performance of the conventional method for training deep neural networks (NNs), the backpropagation.
Vesico-vaginal Fistula Surgery in Uganda.

Background: Childbirth injuries are common in Uganda. This paper describes our experience with Vesico-vaginal Fistula repair and aftercare. Methods: Between 1999 and 2003, 341 consecutive patients underwent VVF repair complicating childbirth trauma. Another 29 VVF patients were seen but not operated because of time constraints. Five new patients who were considered inoperable from the start. Results: The mean age was 27 years and the mean duration of the fistula was 6 years. New cases comprised 82% of the cases. Over half (55%) of the patients were primiparous. Nearly two-thirds (64%) of cases had delivered by Caesarean section. Surgery was attempted in almost every patient regardless of how complicated the VVF was. Only 20% of VVF repairs were assessed as being easy. Early in the series an abdominal approach was generally used for vesico-cervical fistulae following Caesarean section. With increasing experience however, the transvaginal approach became the procedure of choice. The majority were repaired in a single layer. Rarely fat grafts were used. Postoperative care was simplified to free open drainage of the catheter via plastic tubing into a small bucket under the bed. Most patients were allowed out of bed from day two. A high fluid intake was encouraged at all times starting before the operation. Around 90% were closed at the first attempt but a further 10% may have unacceptable stress incontinence. Conclusion: We believe there is a reservoir of untreated VVF patients in Uganda and fistula camps can make a significant contribution to teaching and cure of patients
The noun-verb distinction in Catalan Sign
 Language

This paper investigates the morpho-phonological differences between the members of related noun-verb pairs in Catalan Sign Language. Like parallel investigations in other sign languages, our experimental work provides evidence that the major differentiating factors between related nouns and verbs materialize in the movement component of signs and non-manual markers, thus providing empirical support to the hypothesis that most noun-verb pairs have different morpho-phonological properties. We distinguish different types of movements, which we categorize into four regular morphological subgroups. We also take into account a fifth group that shows no apparent movement distinction. Concerning non-manual markers, we provide empirical evidence that nouns are mostly produced simultaneously with mouthing, in contrast to verbs, which in a smaller proportion are produced mainly with mouth gestures. Crucially, the fifth group presents the largest ratio of mouthing for nouns and even for verbs. We address these findings within an exo-skeletal theoretical syntactic approach (Borer 2005a,b, 2013, 2014).
MANAGEMENT OF COMPLICATIONS OF MUSTARD GAS KERATITIS WITH CORNEAL AND LIMBAL STEM CELL TRANSPLANTATION

Purpose: To report the clinical findings and compare the outcomes of different surgical techniques evolved over time in a large series of patients with delayed-onset mustard gas keratitis (MGK). Methods: This interventional retrospective case series includes patients with complications of delayed MGK. Medical and surgical interventions to address dry eye, limbal ischemia and limbal stem cell deficiency (LSCD), and corneal complications were reviewed. Outcomes of limbal stem cell transplantation techniques such as living-related conjunctival-limbal allograft (lrCLAL) and keratolimbal allograft (KLAL), as well as corneal transplantation techniques including penetrating keratoplasty (PKP) and lamellar keratoplasty (LKP) were compared. Results: A total of 175 eyes of 90 patients (all male) aged 34 to 68 years were included. Mean follow up was 101 months. The most common ocular complication was chronic blepharitis and dry eye. Conjunctival vascular abnormalities and limbal ischemia were observed in 27.4% and 29.7% of eyes, respectively. LSCD necessitating stem cell transplantation developed in 41.1% of eyes. The most common corneal signs were central and peripheral anterior stromal opacity (58.9%) followed by corneal stromal thinning (36.0%) and neovascularization (27.4%). lrCLAL was performed in 32 eyes (18.3%) and KLAL in 40 (22.9%). The rejection-free graft survival rate was 39.1% in the lrCLAL group and 80.7% in the KLAL group at 40 months with mean duration of 24.9 and 68.8 months, respectively (P=0.02). 30 eyes (17.1%) underwent PKP and 51 (29.1%) received LKP. Corneal graft failure was observed in 9 (30%) PKP and 6 (11.8%) LKP eyes. The rejection-free graft survival rate was 39.0% in the PKP and 90.3% in the LKP group at 28 months with a mean duration of 29.6 and 85.0 months, respectively (P<0.001). Conclusion: Chemical warfare victims may ultimately develop significant ocular involvements requiring some sorts of surgical intervention. Limbal and corneal abnormalities can best be managed by KLAL and LKP, respectively.
Review of Packaging Schemes for Power Module

SiC devices are promising for outperforming Si counterparts in high-frequency applications due to its superior material properties. Conventional wirebonded packaging scheme has been one of the most preferred package structures for power modules. However, the technique limits the performance of a SiC power module due to parasitic inductance and heat dissipation issues that are inherent with aluminum wires. In this article, low parasitic inductance and high-efficient cooling interconnection techniques for Si power modules, which are the foundation of packaging methods of SiC ones, are reviewed first. Then, attempts on developing packaging techniques for SiC power modules are thoroughly overviewed. Finally, scientific challenges in the packaging of SiC power module are summarized.
A Case of Pneumothorax in Which Progression of Reexpansion Pulmonary Edema Was Arrested

We report a case of pneumothorax secondary to emphysema in which we arrested reexpansion pulmonary edema. The patient was a 58-year-old male. A chest drainage tube was inserted to manage the secondary left pneumothorax, but further aggravation of dyspnea and frothy airway secretions were observed shortly after drainage. Because reexpansion pulmonary edema was suspected, we intentionally chose to perform oxygen administration and opening of the drain. As symptoms subsided, the patient was put in a right lateral decubitus, and gradual expansion of the lungs was attempted. As chest X-ray showed suspected edema in the left lung, a potent diuretic was administered. Since no exacerbation of symptoms or decrease in transcutaneous arterial oxygen pressure was noted, the patient was kept under observation without requiring further medication. In a clinical situation where a patient shows aggravation of dyspnea and appearance of frothy sputum during reexpansion of collapsed lungs, it is critical to prevent the development of fatal reexpansion pulmonary edema by arresting rapid expansion of the lungs and avoiding the increase in blood flow into the reexpanding lungs.
Young-onset Diabetes in Central Kerala -A Preliminary Report

Out of a total of 1603 patients, 58 patients had the onset of diabetes below 20 years . The most common type of diabetes was IDDM (67%) , followed by FCPD (19%) and NIDDM (14%). The number of FCPD patients in Kerala are decreasing. The IDDM group has more of congenital anomalies and viral infections, prone to ketosis, and required on an average of 44 units of insulin per day for control of diabetes, whereas the FCPD group had the lowest BMI, no ketosis, all had p ancreatic pain and calculi and required 61 units of insulin per day. NIDDM patients had a strong family history of diabetes as compared to the other groups, suggesting g enetic factors in its causation . Retinopathy is present in all three types after 5 years of the onset of diabetes but it is of earlier onset FCPD and of later onset in NIDDM.
RESULTS AND COMPLICATIONS OF ENDOSCOPIC ULTRASOUND GUIDED-FNA IN PATIENTS WITH PANCREATIC AND GASTROINTESTINAL SUB MUCOSAL LESIONS

Background: Linear endoscopic ultrasonography (EUS) is a proven modality for the diagnosis and treatment of different gastrointestinal lesions. The aim of this study was to describe the role of EUS-FNA in the evaluation of pancreatic and submucosal lesions. Materials and Methods: Over a 1-year period, in a prospective descriptive study, patients referred to Naft Hospital, underwent linear EUS. Results: Of the 40 linear EUS performed, 32 (80%) patients had pancreatic lesions which 26 (81%) of these cases were referred for pancreatic tumor biopsy. The most of these tumors (73%) were in the head of pancreas. EUS-guided fine-needle aspiration biopsy was performed in all 26 patients successfully without complications, which in 16 (61.5%) of them the diagnosis of pancreatic malignancy confirmed cytopathologically. Sensitivity and specificity of this method in pancreatic lesions were 84% and 100%, respectively. Eight patients (20%) were referred because of submucosal upper gastrointestinal lesions which in 7 (87.5%) of them GIST were diagnosed. Sensitivity and specificity of EUSFNA in submucosal lesions was 100%. No adverse effect of EUS-FNA was observed. Conclusions: EUS-FNA is a safe method with an acceptable accuracy in the evaluation and diagnosis of pancreatic and submucosal lesions. The results of this study are similar to that reported previously from other countries. Performing this new method requires more gastroenterologists and pathologists experience as well as more support from different societies (such as gastroenterology and surgery).
