Authors: Li Tao , Jiang BA Bo , Zhou Xiaodong 
Published: December 2018

Abstract
Background: To summarize the clinical characteristics of patients with ocular chemical injuries and evaluate their potential relationship with the visual outcome by analyzing the medical records of these patients from January 1, 2012, to December 31, 2017.
Methods: This is a retrospective case series study. Patient data included age, gender, occupational classification, location of ocular chemical injury, initial and final best-corrected distance visual acuity (BCDVA), intraocular pressure (IOP), nature and chemical phase, distribution and severity of chemical injury, management methods, and complications. All variables were evaluated for their potential relationship with visual outcome.
Results: A total of 160 patients were hospitalized with ocular chemical injuries. The majority of the patients were factory workers and arrived at the consultation room less than 24 hours after injury. The most common ocular injury setting, classification of severity, causative chemical, chemical phase, and complications were workplace, grade Ⅱ, unknown and mixed substance, liquid, and elevated IOP, respectively. The risk factors for poor final BCDVA were identified as older age, poor initial BCDVA, and irrigation 24 hours after injury (P < 0.001, P < 0.001, and P = 0.011, respectively).
Conclusion: We elaborate the clinical characteristics and outcomes of patients with ocular chemical injuries in Jinshan District, Shanghai. A comprehensive education program should be established and the use of protective eyewear should be promoted to prevent occupation-related ocular chemical injuries.
Glucocorticoid Induced Paraplegia in a Patient with Intracranial Dural Arteriovenous Fistula: Case Report
Authors: Zhang Hongqi , Ma Yongjie , Lu Jie 
Published: December 2018

Abstract
BACKGROUND:
Glucocorticoid inducing paraplegia has been reported and regard as a diagnostic clue for spinal dural arteriovenous fistulas (DAVFs). Intracranial DAVF in the posterior fossa draining into the perimedullary venous system can induce congestion of spinal cord while often be misdiagnosed and treated with steroid.
CASE PRESENTATION:
A 54-year-old woman presented progressive bilateral extremities weakness, bowel and bladder symptoms. A cervical MRI showed a longitudinally extensive spinal cord lesion from medulla oblongata to level of T4. A diagnose of NMO and cervical spondylopathy was made. On hospital day 2, methylprednisolone was prescribed at dose of 1g intravenous daily. After that, the patient experienced acute paraplegia. Treatment was stopped. And the patient improved on the hospital day 6, almost returned to her initial state. So the diagnosis of SDAVF was suspected. Spinal angiography was performed but the result was normal, and cerebral angiography demonstrated an DAVF fed by the right meningohypophyseal trunk and drain through right petrosal vein and into perimedullary venous system. Operation was performed successfully and the fistula was obliterated. The patient experienced an improvement of weakness and incontinence.
CONCLUSIONS:
We reported a case of intracranial DAVF with acute paraplegia response to intravenous glucocorticoid therapy.Intracranial DAVF can also lead venous congestion of the spinal cord, which induce similar clinical manifestation with spinal DAVF, the MRI examination of spinal cord can also find cord edema and typical enlarged medullary veins.
Serial Magnetic Resonance Imaging Findings in a Patient with Hyperglycemia-Related Osmotic Demyelination Syndrome: A Case Report
Authors: Kim Jong Hyuk , Park Noh Hyuck 
Published: December 2018

Abstract
Background: The authors report serial magnetic resonance imaging findings of osmotic demyelination syndrome (ODS) related to hyperglycemia in a patient with uncontrolled diabetes mellitus.
Case presentation: A 61-year-old man with diabetes was admitted for general weakness and severe thirst. A few days later, he complained of dysarthria, dysphasia, and dysmetria. On admission, he exhibited significant hyperglycemia (33.5 mmol/L [627 mg/dL]), with a glycated hemoglobin level of 18.1%. Other laboratory investigations revealed a sodium level of 133 mEq/L, potassium 3.8 mEq/L, blood urea nitrogen 43.9 mg/dL, with a calculated serum osmolality of 324 mOsm/kg. Brain magnetic resonance imaging (MRI) revealed T2 signal abnormalities that were symmetrical, non-space occupying, and located in the central pons with a peripheral sparing pattern, which were findings suggestive of ODS. In addition, subsequent MRI revealed progression of signal hyperintensity; however, the patient's symptoms were improved and he was discharged after 2 months.
Conclusion: We report a rare case of hyperglycemia-related ODS that exhibited gradual progression in imaging features despite the prompt correction of blood sugar levels and improvement of neurological symptoms
Large diameter hand-dug wells in South Africa
Authors: Gomo Modreck , Kotzé Yolanda , Vermeulen Danie 
Published: December 2018

Abstract
Despite technical advances, traditional large diameter hand-dug wells remain very important in remote and rural communities as a method for gaining access to groundwater for drinking, domestic and agricultural activities. This paper explores and discusses large diameter hand-dug wells in South Africa, with regard to their utilisation, research and development, and the legislative and policy framework guiding their development and use. While large diameter hand-dug wells have featured in national legislative and policy frameworks, and in early technical guidelines, in recent years the subject has not received much attention. There is also little evidence to suggest that large diameter hand-dug wells receive any attention in typical academic and research curriculums. While South Africa's national vision is to provide improved water supply schemes in rural areas under which clean drinking water can be accessed via communal water taps, it is clear that in some rural communities household large diameter hand-dug wells still remain the most feasible and convenient way to provide water, not only for drinking but also for agricultural activities – a key form of livelihood support contributing to poverty reduction. Large diameter hand-dug wells still need attention in the policy arena to improve technical guidance to optimise the development, utilisation and management of these wells.

Published: December 2018

Background:
Tetralone derivatives, important resources for the development of new drugs
which can act in the treatment of central nervous system disorders or participate in synthesis reaction
for the synthesis of various pharmaceuticals, have great research value and a bright prospect in exploitation.

Methods:
A novel chiral HPLC method for efficient enantioseparation of eight tetralone derivative enantiomers
was developed on cellulose based CHIRALPAK IC chiral stationary phase under normal
mode by investigating the effects of type and content of organic modifier, column temperature and flow
rate on retention and enantioselectivity. Besides, the specificity, linearity, stability, precision, accuracy
and robustness of this method were also validated.

Results:
Satisfactory enantioseparation was obtained for all enantiomers in n-hexane/2-propanol mobile
phase system at ambient temperature. The thermodynamic study indicated that the solute transfer from
the mobile to stationary phase was enthalpically favorable, and the process of enantioseparation was
mainly enthalpy controlled. This method met the requirements for quantitative determination of tetralone
derivative enantiomers.

Conclusion:
This study can provide great and important application value for enantioseparation of eight
pairs of newly synthesized tetralone derivative enantiomers under normal mode using CHIRALPAK IC
chiral column.

Authors: Erbe Christina , Klukowska Malgorzata , Timm Hans C , Barker Matthew L , van der Wielen Janneke , Wehrbein Heinrich 
Published: December 2018

ABSTRACT

Objectives:
To assess plaque and gingivitis reduction in orthodontic patients after 4 weeks' use of an oscillating-rotating power brush, irrigator, and mouthrinse.

Materials and Methods:
This was a randomized, examiner-blind, clinical trial comparing plaque and gingivitis outcomes for an experimental power brush/irrigator/mouthrinse oral hygiene routine vs a dental prophylaxis followed by regular manual brushing (positive control). Fifty-one participants with fixed orthodontic appliances in the upper and lower jaw and a minimum of 15 gingival bleeding sites were randomly assigned to experimental or positive control treatment. Both groups were instructed to use their products at least twice daily. At baseline, week 1, and week 4, plaque was evaluated using digital plaque imaging analysis and a conventional subjective index. Gingival inflammation and bleeding were also measured. Analysis of covariance was used to compare groups.

Results:
Fifty-one participants (mean age = 13.9 years) were randomized; 50 (25 per group) completed the study. At baseline, group means were not statistically different (P &gt; .1) for gingival inflammation or bleeding. At week 4, the experimental and control groups had a 10.0% to 32.7% and 5.9% to 6.7% reduction vs baseline, respectively, in plaque (across both methods); 12.6% and 8.3% reduction, respectively, in gingival inflammation; and 50.6% and 37.8% reduction, respectively, in bleeding. At week 4, group differences favoring the experimental group were statistically significant (P &lt; .05) for gingival inflammation, gingival bleeding, and plaque (by conventional and digital imaging indexes).

Conclusions:
Use of a power brush/irrigator/mouthrinse resulted in statistically significantly greater plaque and gingivitis reductions than prophylaxis followed by manual brushing in patients with fixed appliances over 4 weeks.

Authors: Park Hyo-Jin , Choi Sung-Hwan , Choi Yoon Jeong , Park Young-Bum , Kim Kwang-Mahn , Yu Hyung-Seog 
Published: December 2018

ABSTRACT

Objectives:
To determine whether the success rate and primary stability of surface-treated miniscrews differ from those of nontreated miniscrews.

Materials and Methods:
Patients who required one or more miniscrews for the same reason in each quadrant were recruited into a single-blinded, split-mouth, randomized, controlled trial with a 1:1 allocation ratio. Self-drilling miniscrews with two surface types were used: those with no surface treatment, and those with an acid-etched surface treatment. The cumulative success rate and primary stability of each type of miniscrew were examined, and factors potentially affecting the success and failure of miniscrews were investigated.

Results:
Forty patients were included in the study, with a total of 98 orthodontic miniscrews. The overall success rate was 88.8%, and the respective success rates for acid-etched and machined surface miniscrews were 91.8% and 85.7%. The respective mean insertion torques were 13.62 ± 5.95 N·cm and 13.38 ± 4 N·cm, and periotest values measured immediately after insertion were −0.50 ± 2.77 for acid-etched miniscrews and −0.28 ± 3.36 for machined surface miniscrews. There was no significant difference in the mean insertion torques and periotest values according to surface treatment and jaw.

Conclusions:
Neither the success rate nor the primary stability of acid-etched surface miniscrews and machined surface miniscrews differed significantly. There is a high possibility that miniscrews will fall out in patients who have an open bite or those who require total distalization.

ABSTRACTObjectives:To investigate the difference in heritability of craniofacial skeletal and dental characteristics between hypodivergent and hyperdivergent patterns.Materials and Methods:53 Korean adult monozygotic (MZ) and dizygotic (DZ) twins and their siblings were divided into a hypodivergent group (Group 1, SN-MP &lt; 35°, 17 MZ pairs; 11 DZ and sibling [DS] pairs of the same gender) and hyper-divergent group (Group 2, SN-MP &gt; 35°, 16 MZ pairs; 9 DS pairs of the same gender). A total of 56 cephalometric variables were measured using lateral cephalographs. Craniofacial structures were divided into anteroposterior, vertical, dental, mandible, and cranial base characteristics. Falconer's method was used to calculate heritability (h2 &gt; 0.8, high). After principal component analysis (PCA), the mean h2 value of each component was calculated.Results:Group 1 exhibited high heritability values in shape and position of the mandible, vertical angular/ratio variables, cranial base shape, and maxillary incisor inclination. Group 2 showed high heritability values in anteroposterior position of the maxilla, intermaxillary relationship, vertical angular variables, cranial base length, and mandibular incisor inclination. Occlusal plane inclination showed high heritability in both groups. Although vertical structure presented a high overall mean h2 value in Group 1, there were no structures that exhibited a high overall mean h2 value in Group 2. PCA derived 10 components with 91.2% and 92.7% of cumulative explanation in Groups 1 and 2, respectively.Conclusions:It is necessary to estimate or predict growth according to vertical pattern for providing differential diagnosis and orthodontic/orthopedic treatment planning.

Published: December 2018

SUMMARY

Objective:
This randomized, double-blind clinical trial aimed to evaluate the influence of different dentin surface treatments in noncarious cervical lesions (NCCLs).

Methods and Materials:
Twenty-nine patients participated in this study. One hundred sixty-five NCCLs were selected and randomly assigned to three groups: G0 (control group) with phosphoric acid etching for 15 seconds; G1: phosphoric acid etching for 30 seconds; and G2: ultrasound probe applied for 30 seconds on the dentin surface. Class V composite resin restorations were performed (Z350, 3M ESPE, St Paul, MN, USA). The restorations were evaluated at baseline and at six, 12, 24, and 36 months according to the World Dental Federation criteria. Survival curves were obtained using the Kaplan-Meier method and the log-rank test. Comparisons between groups and times were performed using the McNemar and Chi-square tests (α=0.05).

Results:
The presence of failures due to retention was statistically different among the groups (p=0.012), and G0 and G2 showed better clinical performance than did G1. Sensitivity decreased over time in all groups. Marginal discoloration, postoperative sensitivity, and marginal adaptation were not different among the groups (p&gt;0.05).

Conclusions:
The studied dentin surface treatments showed similar clinical performance to the conventional technique at 36 months in terms of marginal discoloration, marginal adaptation, and postoperative sensitivity. In contrast, increased acid-etching time resulted in a higher risk of failure due to retention over time in composite Class V restorations.
