Effects of Temperature Dependent Thermal Conductivity and Viscous Dissipation on Free Convective Flow along a Vertical Flat Plate with Asymptotic Solution
Authors: Islam AKM Safiqul , Alim MA , Karim Md Rezaul , Rahman ATM M
Published: June 2017

This paper reports us the surface temperature distribution effects of free convective flow along a vertical flat plate with temperature dependent thermal conductivity and viscous dissipation with asymptotic solution. The governing equations with associated boundary conditions reduce to local non-similarity boundary layer equations for this phenomenon are converted to dimensionless forms using a suitable transformation. The transformed non-linear equations are then solved using the implicit finite difference method together with Keller-box technique. Numerical results of the velocity and temperature profiles, skin friction and surface temperature profiles for different values of the thermal conductivity variation parameter, the Prandtl number and the viscous dissipation parameters are presented graphically. Also we considered the asymptotic solution for the effect of the thermal conductivity variation parameter, the Prandtl number and the viscous dissipation parameters in skin friction and surface temperature profiles. Detailed discussion is given for the aforementioned parameters. A good similarity is found in small and large value solution with all value solution for the thermal conductivity variation parameter, the Prandtl number and the viscous dissipation parameter for skin friction and surface temperature. Divergence is found near one (1).GANIT J. Bangladesh Math. Soc.Vol. 36 (2016) 33-46

Determination of the Homology and the Cohomology of a Few Groups of Isometries of the Hyperbolic Plane
Authors: Akhter Nasima , Majumdar Subrata
Published: June 2017

In this paper we determine the homology and the cohomology groups of two properly discontinuous groups of isometries of the hyperbolic plane having non-compact orbit spaces and the fundamental group of a graph of groups with a finite vertex groups and no trivial edges by extending Lyndons partial free resolution for finitely presented groups. For the first two groups, we obtain partial extensions and the corresponding homology. We also compute the corresponding cohomology groups for one of these groups. Finally we obtain homology and cohomology in all dimensions for the last of the above mentioned groups by constructing a full resolution for this group.GANIT J. Bangladesh Math.

Slip Velocity Distribution on MHD Oscillatory Heat and Mass Transfer Flow of a Viscous Fluid in a Parallel Plate Channel
Authors: Malapati Venkateswarlu , Dasari Venkata Lakshmi
Published: June 2017

The present investigation deals with the effect of slip on the hydromagnetic pulsatile flow through a parallel plate channel filled with saturated porous medium. Based on the pulsatile flow nature, the transformed conservation equations are solved analytically subject to physically appropriate boundary conditions by using two term perturbation technique. Exact solutions are obtained for the velocity, temperature and concentration fields. In particular skin friction coefficient, Nusselt number and Sherwood number are found to evolve into their steady state case in the large time limit. The results obtained here may be further used to verify the validity of obtained numerical solutions for more complicated transient free convection fluid flow problems. Parametric study of the solutions are conducted and discussed.GANIT J. Bangladesh Math. Soc.Vol. 36 (2016) 91-112

Un conte singulier
Authors: Guillou Paul-Vincent
Published: June 2017

La Barbe Bleue est un conte d’une richesse d’inspiration peu commune. Et l’on ne prête qu’aux riches. Très tôt la postérité a associé cette figure à des personnages historiques voire mythologiques. Barbe Bleue est devenu une figure archétypique de tueur de femmes. Il est lui-même devenu un mythe. En fait, aucun de ces modèles de référence n’est satisfaisant. Cet étonnant conte à la morale ambiguë connut de multiples adaptations tant littéraires que musicales et cinématographiques et suscita l’intérêt non assouvi de nombreux chercheurs.

Authors: Ramachandran Rakesh , Manohar Sai , Somayaji Gangadhara
Published: June 2017

Aim:

Lipids play an important role in cell division and growth and have long been associated with cancers. Smoking is also known to alter serum lipid level. In this study, serum lipid profile in chronic smokers with head and neck malignancy was compared with chronic smokers without head and neck malignancy.

Materials and methods

In this study, 50 chronic smokers with histopathologically proven head and neck malignancy and 50 chronic smokers without malignancy were studied. Fasting blood samples were collected from the subjects and plasma lipid profile estimated.

Results

There is no significant difference in total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, very low-density lipoprotein values between the groups.

Conclusion

There is no significant alteration of serum lipid profile in patients with head and neck malignancies and therefore it cannot be used as a serum marker as a diagnostic tool for early detection.

Medrobotics Flex System for Laryngeal Surgery: A Feasible Study in Two Cadavers
Authors: Roy Soham , Naqvi Syed HS , Karni Ron J
Published: June 2017

Objective

To report the feasibility of Medrobotics Flex® System for laryngeal surgery.

Materials and methods

Cadaver study in research laboratory.

Results

The Medrobotics Flex System was utilized with the Medrobotics Flex Retractor to evaluate robotic laryngeal surgery in a cadaver model. Two surgeons using two cadavers tested the robotic system to expose the larynx and facilitate robotic airway surgery using the Flex Instruments. In both cadavers, these procedures were performed transorally with excellent visualization: supraglottoplasty, arytenoidectomy, epiglottectomy, vocal cord lesion excision, posterior cordotomy, hemilaryngectomy, and endoscopic anterior/posterior cricoid split. Laryngeal cleft repair was limited by availability of suture to close the interarytenoid band. Laryngeal exposure was rated as “excellent” by both surgeons using the robotic platform.

Conclusion

Robotic surgery for the head and neck, while still in relative infancy, remains one of the newest platforms for the otolaryngologist. Currently available robotic platforms, while adapted to head and neck and airway surgery, were not designed for this purpose and pose challenges in size and accessibility to the larynx. The Flex System is specifically designed for head and neck and laryngeal surgery. This system provides outstanding visualization of hard to access areas in the larynx and hypopharynx. The flexible surgical instruments used with the Flex System allow for reasonable surgical exposure and technique. The Flex System may provide an improved robotic experience for transoral laryngeal and head and neck surgery.

Comparison of Clinical and Radiographic Success Rates of Pulpotomy in Primary Molars using Ferric Sulfate and Bioactive Tricalcium Silicate Cement: An in vivo Study
Authors: Marwaha Mohita , Sirohi Kavita , Bansal Kalpana , Srivastava Ankit
Published: June 2017

Introduction

Formocresol has been a popular pulpotomy medicament for many years. It is considered the “gold standard” in pediatric dentistry. However, concerns have been raised over its use in children. It has been reported that formocresol has toxic and mutagenic effects in cell culture, dental crypts, and precancerous epithelial cells. Therefore, additional biocompatible treatment alternatives are required to replace formocresol pulpotomy.

Aims

This study compared the clinical and radiographic success rates of ferric sulfate (FS) and bioactive tricalcium silicate cement (Biodentine, Septodont) as pulpotomy agents in primary molar teeth over a period of 9 months.

Materials and methods

Fifty primary molar teeth, symptom free, requiring pulpotomy in children aged 4 to 8 years were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 25 teeth) and Biodentine (for 25 teeth) were used as pulpotomy agents. Permanent restorations were stainless steel crowns in most cases, in both groups. Patients were recalled for follow-up at 1, 3, 6, and 9 months intervals. The data were statistically analysed using chi-square test.

Results

At 9 months, 96% clinical success rate was observed in the FS and 100% in the Biodentine group. Radiographic success rate in the FS group was 84%, whereas 92% in the Biodentine group at 9 months. No statistically significant difference was found between the two groups.

Conclusion

Biodentine can be used as a pulpotomy agent but further long-term studies are required.

Clinical and Practical Implications of Storage Media used for Tooth Avulsion
Authors: Khinda Vineet IS , Brar Gurlal S , Kallar Shiminder , Khurana Heena
Published: June 2017

Replantation is being widely accepted as an effective treatment option for an avulsed tooth. However, the long-term fate of replanted teeth is unpredictable; it is dependent on various factors, such as the time interval between avulsion and replantation, extra-alveolar storage period (dry storage or storage media), the vitality status of pulp or periodontal tissues and the type and period of splinting. The appropriate use of storage media is an important clinical factor affecting the postoperative prognosis of avulsed teeth following replantation. Hank's balanced salt solution and pasteurized milk are considered to be the most appropriate and clinically recommended storage media for avulsed teeth. The present review discusses the various available storage media for avulsed teeth and their potential maintenance of the vitality of periodontal ligament cells. A brief overview of the effect of clinical factors, such as the storage time, pH, and the osmolarity of storage media on their efficacy is included.

Authors: Shashikiran ND , Ahirwar Pratibha , Maran Priyanka , Kannojiya Pawan Raj
Published: June 2017

Introduction

Dental caries and trauma are the most common oral health problems for many decades. There is need for prevalence data to analyze the nature of the problems and to take necessary steps in improving public health.

Aim and objectives

To assess the prevalence of dental caries and traumatic dental injuries among schoolchildren of age 6 to 12 years in Bhopal city.

Settings and design

Cross-sectional study design was selected. Universal sampling method was followed in this study.

Materials and methods

A total of 1,204 children were examined. The distribution of samples was done based on age, gender, residing area, and type of school.

Statistical analysis

Data were collected and statistically evaluated under chi-square test and analysis of variance.

Results

The overall caries experience (73.17%) was found to be higher than that of traumatic injury experience (20.9%). There was age-related correlation between age and decay, missing, and filled teeth score.

Conclusion

Since most injuries occur at home or at school, educating the individual is the key that will have a great impact on the prognosis of traumatic injuries. Also good food habits need to be instilled in children from a tender age with the help of parents, which is the ultimate solution to fight caries.

Authors: Hegde Rahul , Agrawal Geet
Published: June 2017

Aims and objectives

To measure the prevalence of anterior teeth trauma in 9- to 14-year-old schoolchildren and their association with predisposing factors, such as lip competence, molar relationship, overjet, and variables, such as age, gender, and cause of trauma.

Materials and methods

Epidemiological cross-sectional study was carried out among 3,012 schoolchildren aged 9 to 14 years in Navi Mumbai (Kharghar-Belapur region). The sample size was derived using the stratified random sampling method; we picked six schools from the region. These schools had 3,000 students in the acceptable age group of the study which constituted our final sample size. All children were examined for traumatic dental injuries, and the children with positive findings were further examined for lip competence, Angle's molar relationship, and overjet. The results were statistically analyzed using cross-tabulation and Chi-square test.

Results

The prevalence of dental injuries was 7.3%, and the ratio of male to female children was found to be 1.6:1. The maximum number of traumatic dental injuries was found with class I molar relationship and overjet less than 3.5 mm in children with competent lips. Maximum number of injuries occurred in the age group of 13–14 years. The most predominant type of injury was the enamel fracture and the most common cause determined was due to fall.

Conclusion

The present study is a collection of data on traumatic injuries to anterior teeth, which is seen very commonly in day-to-day practice. The frequency and cause of traumatic injuries to anterior teeth is important for identification of risk groups, treatment needs, and cost involved in order for establishing effective preventive measures.

A Rare Concomitant Occurrence of Talon Cusp in Fused Mandibular Permanent Teeth: Report of Two Cases
Authors: Jangra Babita
Published: June 2017

Fusions of teeth and talon cusp are two rare developmental dental anomalies, affecting both primary and permanent dentitions. Both the anomalies are mostly reported as isolated finding and are rarely associated with other dental anomalies. Talon cusp is more common in maxillary anterior teeth in permanent dentition and fusion is commonly reported in mandibular teeth in primary dentition. The concomitant occurrence of talon cusp and fusion is rare and its occurrence in fused mandibular permanent teeth is also rare. This case report presents two unusual cases of concomitant occurrence of talon cusp with fusion in permanent mandibular incisors. The clinical problems associated with these dental anomalies and importance of their management are discussed in these case reports.

Evaluation of the Correlation between the Vertical Dimension of Occlusion and the Length of the Ear, Nose, and Little Finger: An Anthropometric Study
Authors: Tewary Shivsagar , Kore Abhijeet , Rege Janhavi J , Gosavi Sulekha S , Gosavi Siddharth Y
Published: June 2017

Introduction

The aim of this study was to find out the anthro- pometric correlation of vertical dimension of occlusion (VDO) with the length of ear, nose, and little finger in dentate male and female subjects in Karad population, so as to use this correlation to determine VDO in edentulous patients.

Materials and methods

The study was conducted in Krishna Institute of Medical Sciences Deemed University, Karad, India, on 320 dentate subjects (160 males and 160 females) who fulfilled the inclusion criteria. Anthropometric measurements of VDO, length of ear, length of nose, and length of little finger were recorded using a digital vernier caliper. Simple linear regression model was used to develop a prediction formula for VDO using length of ear, nose, and little finger as the independent variable. Correlation between VDO and length of ear, nose, and little finger was studied using Pearson's correlation test.

Results

Statistical analysis in male and female subjects showed that VDO is significantly different with the length of nose, ear, and little finger. Pearson correlation test showed VDO in males has strong coefficient correlation with the length of the ear (r = 0.500), and strong coefficient correlation with the length of the nose (r = 0.335) in females.

Conclusion

The regression analysis was conducted to formu- late the regression equation for determination of VDO in male and female subjects. The study revealed that the length of ear in males [VDO = 25.591 + 0.565 (length of ear)] and the length of nose in females [VDO = 36.933 + 0.353 (length of nose)] are strongly correlated with VDO.

Clinical significance

The regression formulae were formulated for male and female subjects in dentate patients which can be used to determine the VDO in edentulous patients.

A Three-dimensional Finite Element Analysis of Stress Distribution in the Cortical Bone in Single Tooth Implant and Post Core-treated Tooth subjected to variable Loads
Authors: Rao Suneetha , Arora Honey , Hameed Shahul
Published: June 2017

Purpose

In spite of many advances in the field of prosthetic dentistry, the choice of whether to treat and retain a grossly compromised tooth or to extract and replace with an implant is debatable. Alveolar bone preservation is one of the main criteria to select the treatment option. This is directly affected by the stress generated in the cortical bone under variable loads and is therefore, relevant.

Materials and methods

Two three-dimensional finite element models were generated in relation to maxillary second premolar using ANSYS software. Model-I was parallel-tapered titanium implant with screw-retained titanium abutment and porcelain fused to metal (PFM) crown. Model-P was fiber post and com- posite resin core with PFM crown. Luting cement was resin cement. Both the models were surrounded by homogeneous and isotropic cortical and cancellous bone, and were subjected to variable loads of 300, 400, and 500 N in axial (0°) and nonaxial (15°, 45°) directions.

Results

Stress in the cortical bone in megapascal (MPa) in Model-I/Model-P when subjected to variable loads in newtons(N) in axial direction was 300 N - 37.6 MPa/47.3 MPa; 400 N - 50.2 MPa/63.0 MPa; 500 N - 62.7 MPa/63.0 MPa. 15°- 300 N - 68.5 MPa/65.9 MPa; 400 N - 91.3 MPa/87.9 MPa; 500 N - 114.2 MPa/87.9 MPa. 45° - 300 N - 136.3 MPa/88.9 MPa; 400 N - 181.8 MPa/118.5 MPa; 500 N - 227.2 MPa/118.5 MPa.

Conclusion

Within the limitation of this study, it was concluded that on axial loading, both the treatment modalities showed no significant difference, but on nonaxial loading, the cortical bone in the implant model showed to have considerably higher stress than post core-treated tooth model. Hence, given a choice, this study favors retaining and restoring a compromised tooth with post core and crown rather than extracting and replacing with an implant.

Evaluation of Patient Satisfaction in Implant-supported Dentures retained with Ball and Bar Attachment through Verbal Rating System
Authors: Singla Naresh , Nagarajan Thiruvalluvan
Published: June 2017

Teeth loss is a traumatic experience. It disturbs the total integrity of the masticatory system. Its successful rehabilitation should address a range of biomechanical problems, tolerances, and perceptions. Implant-supported overdenture with two implants placed in the interforamina region is a predictable treatment option in edentulous mandible rather than conventional complete denture as it offers increased stability, comfort, and patient compliance. Success in complete dentures is still an unanswered question as various authors have differing opinion. Patients and prosthodontists often disagree on a successful denture experience. Criteria for quality standards in denture fabrication have been articulated; however patients and prosthodontists often disagree on a successful denture experience. This study was carried out to determine patient satisfaction with implant-supported overdentures and its impact on the treatment outcome. Thirty edentulous patients were randomly divided into two groups to receive implant-supported overdentures supported with two implants in the interforamina region of mandibular arch retained with either ball or ball attachment. Questionnaires were given to the patient before and after treatment at 3- and 6-month interval. Data collected were statistically analyzed. Results obtained from this study show that patients with implant-supported overdentures were more satisfied with the treatment outcome, and there was no significant difference in patient satisfaction between the two groups.

Published: June 2017

Aim:

This study aims to find out the effects of Probiotics, delivered with a lozenge for its effect on clinical and microbiological parameters in subjects with chronic periodontitis after scaling and root planing (SRP).

Materials and methods:

A total of 40 generalized mild to moderate chronic periodontitis subjects were finally enrolled in a double-blind, placebo-controlled, randomized clinical study. Selected subjects after SRP were randomly divided into two groups: Group I (test group) with 20 subjects receiving probiotic tablet once daily and group II (control group) receiving placebo tablets once daily. Clinical parameters and bacterial count for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum were evaluated at baseline, 2, and 4 months after the medication.

Results:

On comparative evaluation between the two groups, results indicated that group I (probiotic group) exhibited statistically significant reduction in both clinical and microbiological levels than group II (control group) over the entire span of the study.

Conclusion:

Our results proved that daily oral supplementation of probiotics could be a useful adjunct to SRP in chronic periodontitis patients.

Comparison of Effectiveness of Two Designs of Interdental Toothbrushes in removing Dental Plaque
Authors: Jayasinghe Vajira P , Tilakaratne A , Perera Kathya L
Published: June 2017

Aim

To compare the plaque removal ability of two designs of interdental toothbrushes (IDTBs) [“tube-like” IDTB = TT and “conical” IDTB = CT] in the posterior part of the mouth in adult patients.

Materials and methods

The study sample consisted of 107 adult patients who were in the periodontal maintenance phase having completed treatment for “chronic mild–moderate gingivitis.” Each selected patient was subjected to plaque scoring in the posterior sextants. Four sites per tooth were scored after plaque disclosing. The percentage of plaque was calculated. One of the two designs of IDTBs (TT or CT) was randomly assigned for each patient. They were instructed to carry out eight strokes back-and-forth in the relevant interdental spaces, following demonstration of the technique on a model. The interdental surfaces were reexamined for remaining plaque, and the plaque score was taken. The percentage of reduction of plaque after using the IDTB was calculated.

Results

The mean interdental plaque score for the “TT design” group (n = 56) was 82% initially, whereas the same for “CT design” group (n = 51) was 78%, and this difference was not significant statistically. Following use of TT design, the plaque score in this group was reduced to 24%, which is a 71% reduction from the initial plaque score. This reduction was significant statistically (p < 0.004; t-test). The CT design also showed a dramatic reduction (79%) in plaque score following use of this design (p < 0.007; t-test).

Conclusion

Although both designs (CT and TT) were highly effective in posterior interdental spaces, the CT design appeared to be better than TT design in controlling interdental plaque.

Effects of Silane on the Push-out Bond Strength of Fiber-reinforced Resin Posts luted with different Self-adhesive Resin Cements
Authors: Radnai Marta , Rajnics Zsolt , Marada Gyula , Moetaz El-Hag
Published: June 2017

Aim

The present study was completed to evaluate the effect of silane on the push-out bond strength on fiber-reinforced posts. The intention of the study was also to determine if there was a regional relation between the adhesive system and the push-out bond strength of the fiber post.

Materials and methods

Fifteen single rooted human teeth were endodontically treated and 2 mm diameter glass fiber-reinforced composite posts were cemented in the root canal. In the first group Futurabond DC without silane, in the second group the same luting material after silane treatment of the posts, and in the third group Clearfil DC Core System without silane were used to lute the posts.

After complete setting of the luting agents three 2-mm-thick slices were obtained from the cervical, middle, and apical regions of the roots. The specimens were subjected to push-out test in special equipment. Bond strength data were analyzed with analysis of variance tests.

Results

The Rebilda posts cemented with Futurabond DC without silane had the highest push-out bond strength at the coronal region (164.71 N ± 72.12), while the posts cemented with Clearfil without silane had the lowest value at the apical region (94.86 N ± 34.14). Silane had no significance on the push-out bond strength (p = 0.909); however, the root canal dentin regions had a significant effect (p < 0.010).

Conclusion

This study did not show any significant differences among different luting protocols. The bond strength was significantly higher in the coronal region due to the greater cemented surface area and the difference in dentin structure.

Clinical significance

Based on the results of the push-out tests, the retention of the posts did not depend on the luting methods; however, the region of the root canal played a significant role.

A Modified Three-piece Base Arch for en masse Retraction and Intrusion in a Class II Division 1 Subdivision Case
Authors: Lekhadia Dhaval Ranjitbhai , Hegde Gautham
Published: June 2017

This case report describes the orthodontic and orthopedic treatment of an 18-year-old male patient who presented with prognathic maxilla, deep bite, low mandibular plane angle, and proclined incisors. Modified three-piece base arch was used for the intrusion and retraction of maxillary incisor. En masse retraction was achieved in 6 months. Reduced time for retraction was attributed to a single stage of retraction unlike Burstone three-piece intrusion base arch where canines are individually retracted followed by retraction of incisors. A modified utility arch was used in lower arch followed by a continuous archwire technique. The case was finished using bite settling elastics on a continuous archwire. The step between canine and premolar was corrected in the finishing phase of treatment. The final treatment outcomes were satisfactory and true intrusion was achieved with proper selection of biomechanics.

Efficiency of Mandibular Advancement Device and Bilevel Positive Airway Pressure Treatment for Severe Obstructive Sleep Apnea
Authors: Keyf Filiz , Firat Selma , Ciftci Bulent
Published: June 2017

Recently, attention to oral appliance therapy, as mandibular advancement device (MAD), has increased. Mandibular advancement device is a popular alternative treatment, particularly for mild to moderate obstructive sleep apnea (OSA). Oral appliances for treating severe OSA are recommended for patients who failed to comply with continuous positive airway pressure treatment. This clinical report presents the treatment outcome of oral appliance therapy and bilevel device in a 70-year-old man with severe OSA and also having respiratory disturbance index (RDI) of 62.7. Polysomnographic (PSG) evaluation was performed before and about 1 week after continuous use of the MAD and then with bilevel device. The results were compared, and RDI decreased 27.5 per hour with the custom MAD, whereas RDI decreased 3.1 per hour with bilevel device. Improved PSG parameters showed that bilevel device was efficient in treatment.

Dentin Dysplasia Type I: Report of Two Cases
Authors: Azimi Somaye , Jafari Soudeh , Farzanegan Amir , Elmi R Zahra
Published: June 2017

Objectives

In this article, we report two cases of type I dentin dysplasia (DD): the first case is subtype “d” DD and second case is severe form of DD type I, which presents all of four subtypes and describes characteristics and the management of this type of teeth anomalies.

Materials and methods

Dentin dysplasia is a rare abnormality of dentin that involves both primary and permanent dentition. The normal shape of crown, short roots or its total absence, pulp chamber obliteration, crescent-shaped pulp, pulp stone, and periapical radiolucencies are the characteristics of DD type I.

Conclusion

There are many problems in the management of a patient with DD. Depending on root development and pulp canal situation, endodontic treatment and tooth extraction are applied in teeth with pulp necrosis and periapical abscess. The prognosis of DD largely depends upon the age at which the diagnosis is made, and the quality of the treatment provided.

Authors: Ghasempour Maryam , Seyedmajidi Maryam , Forooghi Ramin , Gharekhani Samane
Published: June 2017

Aim

This article aimed to report the case of a complex odontoma interfering with tooth eruption.

Background

A common local factor causing tooth impaction or interfering with eruption of teeth is odontoma.

Case report

This case report represented a case of complex odontoma in a girl child overlying the crown of first permanent molar, which involved dental follicle and seemed to be interfering with tooth eruption. Surgical removal was done and follow-up was scheduled to control tooth eruption.

Conclusion

Odontoma as a local factor potentially interfering with tooth eruption can be resolved if it is detected early.

Clinical significance

A routine radiographic survey with panoramic images in mixed dentition period and clinical oral examination would be useful to early detection of tooth eruption problems.

Republic of Kazakhstan
Authors:   International Monetary Fund. Middle East and Central Asia Dept.
Published: June 2017

This Selected Issues Paper evaluates Kazakhstan’s oil rules, current fiscal stance, and long-term sustainability. The sharp and sustained drop in oil prices since 2014 has reduced the value of Kazakhstan’s oil wealth. Kazakhstan’s non-oil deficit path has been higher than suggested by long-term benchmarks, and adjustment is needed in the coming years to avoid fiscal sustainability risks and to promote intergenerational equity. Price-based fiscal rules can help anchor short- and medium-term fiscal policy. The non-oil deficit path introduced in the new National Fund of the Republic of Kazakhstan concept is broadly consistent with the proposed approach and should be followed by timely and decisive implementation of revenue and expenditure measures.

Published: June 2017

Background

This study presents the long-term results of the Cementless Spotorno (CLS) total hip arthroplasty system and an analysis of factors associated with clinical and radiographic outcome.

Methods

We studied a series of 120 consecutive CLS arthroplasties in a young patient group (mean age at surgery: 55.9 ± 5.9 years). The Merle d'Aubigné-Postel score, polyethylene (PE) wear, and radiographic status were recorded during follow-up. Survival analyses, repeated-measures analysis of variance, and a nested case-control study were used for statistical evaluation.

Results

After a mean follow-up of 14.6 years (range 0.1-24.2 years, including revisions and lost to follow-up), 24 revisions had been performed, 16 of which for aseptic cup loosening. Kaplan-Meier survival analysis showed a 24-year survival of 72.8% (95% CI, 63.0%-82.6%) with revision for any reason as endpoint, and 80.1% (95% CI, 70.9%-89.3%) for revision for aseptic cup loosening. Mean final Merle d'Aubigné-Postel score was 16.1 points (range 7-18). Mean PE wear at final follow-up was 2.3 mm (range 0.6-6.8 mm). A higher rate of PE wear was associated with better clinical scores but also with revision for cup loosening. Factors associated with more PE wear were: younger age at surgery; 32 - mm head; longer follow-up; and steeper inclination angle.

Conclusions

Beyond 10 years, the CLS stem is reliable, but the high revision rate for aseptic cup loosening is concerning, specifically with better performing (cementless) alternatives available.

Introduction

Gait analysis is one of the poorly understood dimensions of the functional results obtained after periacetabular osteotomy (PAO) due to dysplasia of the hip.

Materials and methods

Spatiotemporal parameters as well as coronal and sagittal plane kinematics and moments were compared among three demographically similar groups of subjects: (i) 23 patients with excellent results according to the Harris Hip Score (HHS) (mean 6.6 years of follow-up); (ii) 12 patients with good and fair results according to the HHS (mean 9.3 years of follow-up); and (iii) 35 asymptomatic controls.

Results

50% of the analysed sagittal plane kinematic parameters were significantly better (p<0.05) in the control group not only for the hip joint but also for the ipsilateral knee and ipsilateral ankle. A vast majority of the other evaluated gait parameters resulted similar among the groups (p>0.05).

Conclusions

In our experience, most of the gait parameters after PAO are close to those observed in control subjects; however, the obtained pattern cannot be classified as a completely normal gait. The excellence in terms of functional results seems not to be determined by the achievement of this theoretical goal.
Radiographic Outcomes of Cable-Plate versus Cable-Grip Fixation in Periprosthetic Fractures of the Proximal Femur
Authors: Ricciardi Benjamin F. , Nodzo Scott R. , Oi Kathryn , Lee Yuo-yu , Westrich Geoffrey H.
Published: June 2017

Background

Newer generation cable-plate designs are commonly used for periprosthetic proximal femur fractures; however, comparisons relative to cable-grips remain limited. The aim of this study was to compare radiographic healing rates of cable-plate versus cable-grip fixation for periprosthetic proximal femur fractures.

Patients and methods

Consecutive patients with an acute or chronic Vancouver A, B1, or B2 periprosthetic proximal femur fracture undergoing trochanteric fixation with a cable-plate (n = 46 cases) or cable-grip (n = 24 cases) system were identified retrospectively from a single-centre hospital database (mean follow-up 28 months [range 6-89 months]). Demographics, radiographic fracture healing, and complications were compared between the 2 groups. Radiographic union rates were not different between the cable-grip versus cable-plate group (67% vs. 76% respectively; p = 0.4). Healing rates of greater trochanteric fractures alone were not different between the cable-plate versus cable-grip groups (75% vs. 71% respectively; p = 0.38). The cable-plates were used for a more diverse range of fracture patterns relative to the cable-grips.

Results

An increased number of cables was associated with radiographic healing (odds ratio 14 [95% confidence interval 2-64]; p = 0.01), and body mass index had a negative correlation with radiographic healing (odds ratio −0.4 [95% confidence interval 0.5-0.9].

Conclusions

Similar rates of periprosthetic fracture healing were seen using a cable-grip versus cable-plate system; however, the cable-plate system could be used for a more diverse range of fracture patterns.
Total Hip Arthroplasty in Young Patients with Post-Traumatic Arthritis of the Hip
Authors: Swarup Ishaan , Sutherland Ryan , Burket Jayme C. , Figgie Mark P.
Published: June 2017

Background

Post-traumatic arthritis of the hip is a degenerative condition that commonly affects young patients. In this study, we evaluate long-term implant survival and patient-reported outcomes after primary total hip arthroplasty (THA) in patients aged 35 or younger with post-traumatic arthritis of the hip.

Methods

We conducted a retrospective study with follow-up. A chart review was performed to identify young patients with post-traumatic arthritis of the hip treated with primary THA. Follow-up surveys were conducted to determine implant survival and patient-reported outcomes. Implant survival was assessed using Kaplan-Meier survival analysis, and patient outcomes were determined using the hip disability and osteoarthritis outcome score (HOOS).

Results

We studied 42 patient s (44 THAs) with a mean time to follow-up of 14 years. The 10-year implant survival rate was 87% and 20-year implant survival rate was 41%. Implant survival did not differ based on patient age, gender, implant type, bearing surface, or use of cement for implant fixation (p>0.05). The mean HOOS scores at follow-up were 87 for pain, 85 for symptoms, 89 for ADLs, and 76 for sports. HOOS scores were significantly worse in patients that had undergone revision THA (p<0.05).

Conclusions

Young patients with post-traumatic arthritis of the hip have good long-term outcomes after THA. However, revision THA is predictive of worse long-term outcomes.
Determination of Structural Femoral Head Allograft Viability and Integrity with a Novel Diagnostic Tool: SPECT/CT. A Preliminary Study
Authors: Kilicarslan Kasım , Yalcin Nadir , Bicici Vedat , Ozdemir Elif , Bingol Izzet , Turkolmez Seyda
Published: June 2017

Objective

To evaluate the viability and integrity of fresh frozen bulk femoral head allografts obtained from the institutional bone bank that were used to reconstruct severe acetabular defects and to validate the SPECT/CT method which gives both anatomical and functional data for this purpose.

Methods

We retrospectively reviewed 9 patients (6 female, 3 male; mean age 63.6 years). Preoperative and postoperative leg lengths, existence of the Trendelenburg sign, range of motion of the hip, visual analogue score (VAS), Harris Hip Score (HHS) and any complication were assesed at each follow-up. Radiographically, position of the cup, signs of loosening or migration, and union of the graft were all determined. At the latest follow-up, patients were evaluated with hybrid SPECT/CT.

Results

The average duration of follow-up was 38.1 months (24-50 months). The overall mean HHS and VAS scores were significantly improved (p<0.05). When hybrid SPECT/CT results were evaluated, the vascular phase of scintigraphy showed hyperaemia of the graft and the bone phase of scintigraphy showed normal or increased radiotracer uptake in the graft site in 7 patients. SPECT/CT images were used to determine the exact localisation of osteoblastic activity. 1 patient with minor resorption of the graft without clinical symptoms revealed mild osteoblastic activity. The patient who had no activity in the graft site was rerevised because of infection.

Conclusions

Institutional bank allografts are still excellent options for treating large acetabular defects in revision total hip arthroplasty where trabecular metals are not available or in common use. The Hybrid SPECT/CT method is a reliable, noninvasive method for evaluating both the integrity and viability of a bulk graft in 3-D.
