OBJECTIVEAlthough it is well known that major curve severity in adolescent idiopathic scoliosis (AIS) is inversely related to self-image, surgeons often encounter patients who complain of low self-image with preoperatively mild curves or postoperatively well-corrected main curves, suggesting the presence of other factors. This study examined factors contributing to self-image in AIS.METHODSA total of 86 consecutive patients who underwent posterior spinal fusion for AIS Lenke 1 or 2 curves and were followed for a minimum of 2 years were included in this study of patient self-image based on data that included scores reported on the Scoliosis Research Society survey (SRS-22r). The authors evaluated sex, BMI, Risser grade, age, angle of trunk rotation, Cobb angle of the main thoracic (MT) curve, Cobb angle of the thoracolumbar/lumbar (TL/L) curve, apical vertebral translation (AVT), T5–12 kyphotic angle, and clavicular angle. Univariate and multivariate general linear models were employed to identify preoperative and 2-year postoperative factors that impact self-image.RESULTSUnivariate analysis revealed no significant correlation between preoperative MT curve Cobb angle and SRS-22r self-image score (p = 0.51), although patients with a higher MT curve AVT had a significantly worse preoperative self-image (p < 0.01). Two years postoperatively, larger Cobb angle of the TL/L curve (p = 0.01) and higher Risser grade (p = 0.03) resulted in significantly lower self-image scores. In multivariate testing, preoperative MT curve AVT remained significantly related to diminished self-image (p < 0.01). Two years later, higher TL/L curve (p < 0.01), Risser grade (p = 0.03), and MT curve AVT (p = 0.03) had significant associations with lower self-image scores.CONCLUSIONSPreoperative MT curve AVT appears more strongly related to self-image than does Cobb angle. Two years postoperatively, persistent TL/L region curvature and high Risser grade may also be associated with diminished patient self-image.

OBJECTIVEEarly-onset scoliosis (EOS) is not uncommon in patients with neurofibromatosis type 1 (NF1). Despite conservative treatment, spinal deformities progress and require early surgical intervention. To avoid potential interference with chest and trunk growth, growing rods (GRs) have been used effectively in EOS of various etiologies. In this study the authors sought to analyze the outcomes of GRs in EOS patients with NF1.METHODSThis was a retrospective single-center cohort study that included consecutive EOS patients with NF1 who were treated with GRs and were followed up for a minimum of 2 years. Clinical and radiological analyses were performed preoperatively and until the last follow-up.RESULTSFrom to 2008 to 2017, 18 patients (6 male, 12 female) underwent GR surgery (14 single GRs, 4 dual GRs) at a mean age of 8 ± 2.1 years. Mean follow-up was 5 ± 2.4 years. Fifty-five lengthenings were performed at a mean rate of 3 lengthenings per patient (range 0–7). Ten of 14 single GRs (71%) were converted into dual GRs during treatment. No patient underwent definitive posterior spinal fusion (PSF) at GR treatment completion. The mean initial and last follow-up major curves were 57° and 36°, respectively (p < 0.001, 37% correction). The average T1–S1 increase was 13 mm/yr. Six of 9 hyperkyphotic patients had normal kyphosis at last follow-up. There were 26 complications involving 13 patients (72%), with 1 patient who required unplanned revision. The primary complications were instrumentation related, consisting of 17 proximal hook dislodgments, 6 distal pedicle screw pullouts, and 2 rod fractures. Only 1 patient experienced a mechanical complication after dual GR implantation. There were no wound infections.CONCLUSIONSThe GR technique provided satisfactory spinal deformity control in EOS patients with NF1 while allowing substantial spinal growth. Adequately contoured dual GRs with proximal hooks placed in nondystrophic regions should be used to minimize implant-related complications. Surgeons should not attempt to correct kyphosis at GR implantation.

BACKGROUND: Hepatitis B virus infection is a global public health problem. The virus has infected more than one-third of the global population. It has been estimated that 360 million chronic carriers are living around the world with a high risk for developing cirrhosis, hepatic carcinoma and hepatic failure. OBJECTIVE: The aim of this study was to determine the prevalence of some hepatitis B markers among pregnant women attending antenatal clinic in Sokoto Specialist Hospital, Nigeria. METHODS: The hepatitis testing was carried out using the Skytec-Rapid Diagnostic HBV-5 rapid kit (Skytec-Rapid Diagnostic, USA). The kit is based on lateral flow chromatographic immunoassay for the qualitative detection of HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb in human serum or plasma. Panel format can conveniently test for five targets at once and utilizes all markers to help distinguish between acute and chronic infections. RESULTS: Out of 117 pregnant women tested, 15 were positive for HBsAg (12.8%), 6 positive for HBsAb (5.1%), 1 for HBeAg (0.9%), 14 tested positive for HBeAb (12.0%), and 14 tested for HBcAb (12.0%). The prevalence of HBsAg, HBsAb, HBeAg, HBcAb and HBcAb was compared based on ethnicity. HBsAb was significantly higher among the Hausa ethnic group (p= 0.001). The prevalence of HBsAb, HBeAg, HBcAb and HBcAb was not affected by ethnicity (p> 0.05). The prevalence of HBsAg, HBsAb, HBeAg, HBcAb and HBcAb was compared based on age. Infection by the hepatitis B virus markers was higher among young adult and middle age groups. The difference was however not statistically significant (p> 0.05). The prevalence of HBsAg, HBsAb, HBeAg, HBcAb and HBcAb was compared based on the educational status, previous history of blood transfusion, jaundice, employment status and previous history of still births among the pregnant subjects. There were no statistically significant differences in the prevalence of Hepatitis B virus markers (p> 0.05). CONCLUSION: The study observed a high prevalence of various hepatitis B viral markers among pregnant women attending antenatal care in Specialist Hospital Sokoto. There is need for routine screening of all pregnant women and infants born to hepatitis B positive mothers. Government and non-governmental organizations should intensify efforts to enlighten the general population on the public health importance of the disease and the importance of hepatitis screening. There is also need for the development of a treatment protocol for the management of pregnant women positive for hepatitis B to prevent mother to child transmission. There is an urgent need for the implementation of evidenced-based best practice of providing universal vaccination against hepatitis B for all hepatitis B negative women of child bearing age in particular and all Nigerians in general.

“The Surgery” is the product of a live model study and an intuitive collage that evolved into the representation of my memories observing a surgical procedure. My most prominent memory is the anesthesiologist comforting and holding the patient’s hand, asking her to count downwards from ten as her time and sensations slowly vanished. The elements in “The Surgery” are inspired on visions and sensations described by people that have been under the effects of anesthesia.

Published: April 2020

This study was concerned at a limestone quarry located southeast of Helwan city, Egypt, in order to investigate the effect of hydric swelling on the geomechanical aspects of limestone rocks. The Volume of Egyptian limestones change due to the presence of clay minerals (swelling/shrinking). These changes in volume induced by changing environmental conditions, high temperature and fluctuation of the relative humidity, causes accelerated physical deterioration of limestone. The rainfall is infrequent, and it is usual for the area to have no precipitation for successive months. There is a remarkable variability in daily temperature between summer and winter. The hot and arid environment that controls the geological development can affect the engineering behavior of local sedimentary stones. Petrographic investigation by scanning electron microscopy (SEM) of Helwan limestone (biomicritic limestone) revealed the existence of smectite and glauconite within the stone. The clay fraction extracted from Helwan limestone is equal to 10 % by weight. The analysis of oriented clay mounts by X-ray diffraction (XRD) confirmed the dominance of smectite in the clay fraction.To study the effect of the clay content on the mechanical behavior of Helwan limestone, hydric swelling tests were performed at first by using a displacement sensor, afterwards, the effect of a sequence of wetting/ drying cycles on the stone strength was determined by the unconfined compressive strength (UCS) test. Results confirmed that the strength loss of the limestone is directly proportional to the degree of swelling of the clay, as expected. This highlights the importance of this parameter for selecting stones in new construction or for replacing purposes, and for establishing preventive measurements to minimize this damage in historic buildings.

Authors: Rahman Mohammad Asifur 
Published: April 2020

Inflammatory myofibroblastic tumour (IMT) is an extremely rare, benign softtissue lesion of unknown aetiology and pathogenesis that mimics malignant lesions clinically and radiologically found in the maxillofacial region. It occurs primarily in the lungs but occurred in other extra-pulmonary sites. Histologically these lesions appear as an inflammatory infiltrate within a variable of myofibrotic background. The current mode of treatment for inflammatory myofibroblastic tumour (IMT) is surgical excision with regular follow up. In this case report a 40 years old female presented with an intraosseous inflammatory myofibroblastic tumour (IMT) in the left side of mandible which was treated by surgical excision of the lesion. This article also describes the clinicopathological features and treatment of a case of inflammatory myofibroblastic tumour (IMT) of the mandible.

Published: April 2020

Globulomaxillary cyst found in between the roots of lateral incisor and canine of maxilla and is a non-odontogenic developmental origin. It is usually diagnosed by routine radiographic examination and it is inverted peer shaped radiolucent lesion. Adjacent teeth remain vital. Complete enucleation or marsupialization is a treatment option for this. This case report is to observe the expected results after marsupialization followed by enucleation. An eighteen years old boy noticed a painless swelling for 1 year at the left side of upper lip and we performed surgery enucleation after doing marsupialization. Here, marsupialization done to promote bone regeneration and to avoid injury to vital structures and possible fracture. Patient was followed for 3 months after enucleation and the radiolucent area was gradually reduced.This article reports the management of a globulomaxillary cyst in at two-stage procedure and it was more conservative. It might be a good treatment option for management of globulomaxillary cyst.

The Jurassic rift succession of East Greenland has been intensely studied over the last 25 years, particularly within the main outcrop areas of Jameson Land and Wollaston Forland. The more isolated and poorly known outcrops on Traill Ø, Hold with Hope, Hochstetter Forland and Store Koldewey were investigated in the late 1980s and mid-1990s in order to develop a better regional understanding of the Jurassic in eastern Greenland.
This collection of seven papers focuses on stratigraphic and depositional aspects of the Jurassic at these localities. Comprehensive descriptions of the Jurassic on Hold with Hope and south-eastern Traill Ø are accompanied by papers covering fluvial deposits and new ammonite collections from the Middle Jurassic of Traill Ø. The bulletin is concluded by studies of the dinoflagellate cyst stratigraphy of the Middle and Upper Jurassic of Hold with Hope, Hochstetter Forland and Store Koldewey.

Published: April 2020

Nine
lignin-degrading bacteria were isolated from petroleum-contaminated soil and animal
manure samples and characterized by 16S rRNA sequence analysis. Three isolates
were identified as Enterobacter cancerogenus, two as Enterobacter
ludwigii, one as Citrobacter sedlakii,
one as Citrobacter farmeri, one as Klebsiella pneumoniae, and one as Citrobacter murliniae.
These bacteria used ligno sulphate as
the sole carbon source but did not
utilize kraft lignin (KL) as the sole source of carbon and energy. For this reason, basic nutrients, such as 1.0% glucose
(w/v) and 0.5% peptone (w/v), were used as additional carbon and nitrogen
sources to stimulate bacterial growth for KL decolorization.
Under these conditions, the isolates L1, L2, L3, L4, PT21, PT22, PT41, G1, and
C1 degraded kraft lignin by 37 %, 14 %, 20%, 43%, 48%, 51%, 28%, 60%, and %99,
respectively. The decolorization of Remazol Brilliant Blue R (RBBR) by the
isolates was analyzed. The isolates were decolorized at 20-90 % of RBBR,
respectively.

The article is about possibilities of using an educational potential in the process of developing human capital in an enterprise company. Research conducted at a large enterprise that is part of a global corporation. The author presented the system of professional development of employees. The results of the study show that a modern production company at the same time is an organization that assesses the value of human capital for the effectiveness of the company. The way in which the system of employee professional development is formed indicates that the researched enterprise applies the principles that are specific for a "knowledge-based organization". This means creating an organization where the system of acquiring and transferring new knowledge is not the domain of a narrow group of specialists, but becomes an integral part of every lesson, is a usual procedure and task of each employee.
Forms of used trainings and its evaluation by management are an interesting aspect of the employee improvement system in the enterprise company. An analysis of this material helps to use it in the methodological preparation of the adult learning process and the evaluation of learning effectiveness.

ФОРМУВАННЯ ХУДОЖНЬОГО СМАКУ СТУДЕНТІВ МИСТЕЦЬКИХ СПЕЦІАЛЬНОСТЕЙ У ПРОЦЕСІ ВИВЧЕННЯ КУРСУ «ІСТОРІЯ МИСТЕЦТВ»
Authors: Торчевська Наталя 
Published: April 2020

У публікації на основі загальнонаукових методів: аналізу, синтезу, порівняння та узагальнення визначено сутність поняття «художній смак» та виокремлено форми роботи з формування художнього смаку студентів митецьких спеціальностей у процесі вивчення курсу «Історія мистецтв». «Художній смак» – це складна інтегративна якість особистості, основа розвитку духовності та активно-творчої її діяльності; здатність до сприймання, аналізу й естетичного оцінювання творів мистецтва відповідно до сформованих ідеальних переконань про прекрасне. Художній смак особистості виявляється у процесі естетичного оцінювання, під час висловлювання власних суджень щодо творів мистецтва керуючись естетичними почуттями, потребами, світоглядом та знаннями. Передусім формування художнього смаку студентів мистецьких спеціальностей залежить від успішного оволодіння знаннями з курсу «Історія мистецтв», а також від налагодження міжпредметних зв’язків із циклом фахових дисциплін. Так, студенти набувають системних знань про виникнення та історичний розвиток основних видів, жанрів мистецтва; розуміння особливостей художніх стилів; вивчення кращих зразків світового мистецтва, їх сприймання, аналіз і оцінювання відповідно до ідеальних уявлень про прекрасне, що є основою формування художнього смаку. Виокремлено форми і методи роботи з формування художнього смаку студентів мистецьких спеціальностей у процесі вивчення курсу «Історія мистецтв»: аналіз творів мистецтв за спеціальним алгоритмом; створення ілюстрованих словників мистецтвознавчих термінів, понять, напрямів мистецтва; виступи з підготовленими презентаціями (метод ілюстрації); застосування інформаційно-комунікаційних технологій (методи спостереження і ілюстрації); відвідування музеїв мистецтва, персональних виставок, екскурсії до пам’яток архітектури, творчі зустрічі (словесні і наочні методи: бесіда, дискусія, спостереження, ілюстрація); відвідування екзаменаційних переглядів; відвідування екзаменаційних переглядів, виконання практичних форм роботи (методи графічних вправ, замальовки).
Ключові слова: історія мистецтв, художній смак, мистецька освіта, естетичне виховання.
