Afet ve Acil Durumlar İçin Sağlık Personelinin Hazırlıklı Olma Durumu
Authors: DİNÇER Samet , KUMRU Seda
Published: March 2021

Afetler, öngörülemeyen bir zamanda bir toplumun günlük yaşamını olumsuz etkileyen ve genellikle sağlık hizmeti ihtiyacına yol açan olaylardır. Bu çalışmanın amacı araştırmaya katılan sağlık personellerinin afet ve acil durumlar için hazırlıklı olma durumunun, kendi görüşleri doğrultusunda değerlendirilmesidir. Bu araştırma tanımlayıcı bir çalışma olup araştırma verileri, araştırmacılar tarafından oluşturulan anket ile toplanmış ve 276 anket değerlendirilmiştir.

Katılımcıların %23,2'si kimyasal, biyolojik, radyolojik ve nükleer olayların olması durumunda maruz kalan hastalar için uygulanması gereken prosedürü bildiğini ifade etmiştir. Yangın-patlamalar ile gaz kaçağı durumlarında uygulanacak prosedürleri bildiğini ifade edenlerin payı sırasıyla %35,9 ve %31,5’tir. Katılımcıların %60,2’si hastanede olası bir tahliye durumunda uygulanması gereken prosedürü bilmediğini ya da kısmen bildiğini ifade etmiştir (hayır %29; kısmen %31,2). Araştırmaya katılan sağlık personelinin görüşlerine göre belirlenen afet ve acil durumlara hazırlıklı olma durumunu etkileyen değişkenler; meslekte ve hastanede çalışma yılları, afet deneyimine sahip olmak, afet eğitimi ve tatbikatına katılmak, afet planını okumak, afet planını hazırlamak ve güncelleme çalışmalarına katılım olarak belirlenmiştir.

Çalışmanın bulgularına göre, sağlık personelinin afet ve acil durumlara hazırlıklı olmalarında öncelikle hastane afet planının tüm çalışanlar tarafından bilinmesi ve anlaşılması önemlidir. Bununla birlikte, çalışanların afetlere hazırlık eğitimleri ve tatbikatlarla desteklenmeleri gerekmektedir. Özellikle, mesleğinin ilk yıllarındaki sağlık personeline afet yönetimi eğitimi verilmesi gerektiği düşünülmektedir. Afetlere hazırlık çalışmalarında öncelik verilmesi gereken hususlar kimyasal, biyolojik, radyolojik ve nükleer olaylar ile ilgili prosedürler, terör ve sabotaj gibi durumlarda uygulanacak prosedürler, hastaneden tahliye prosedürleri, triyaj uygulaması gibi konulardır.

Glossolalia is currently a relevant topic. There is much controversy and debate about the practice of speaking in tongues. This paper will conduct a comparative analysis of tongues in 1 Corinthians and Acts. The practice referred to is specifically whether the Bible allows simultaneous speaking in tongues based on both books. Also regarding the speaking in tongues, whether it must be understood by others or is it necessary for someone to interpret it. This situation also occurs in the current context. Believers in some churches when in a worship (singing or praying) together speaking in tongues and without interpretation. The author finds that there are significant differences regarding the practice of speaking in tongues as instructed by Paul in 1 Corinthians and the story of speaking in tongues as written by Luke in Acts. In fact, there is an interpretive vacuum that contemporary interpreters must fill. The author uses a comparative method and a grammatical-historical hermeneutic approach to the biblical text.
Pergeseran Perspektif Teologi Penggembalaan Dengan Layanan Virtual Pada Masa Pandemi Sekarang dan Nanti
Authors: Harmadi Mariani , Budiatman Adi Dharma
Published: March 2021

Sebelum pandemi covid-19 pola penggembalaan berkiprah di dunia nyata dan pada masa pandemi hijrah ke dunia maya dengan tantangan tersendiri walau terjadinya di ruang dan waktu yang tanpa batas. Namun dengan komposisi jemaat yang tidak berimbang antara native-digital dan migrant-digital, maka perspektif teologi penggembalaan sebagai dasar yang sudah teruji dan mapan mengalami gugatan untuk bergeser demi mengemban tugas dan fungsi sebagai gembala terhadap domba-dombanya yang secara manusia sedang mengalami penderitaan dan menghadapi ujian iman. Kejenuhan atas dampak pandemi yang berlangsung tanpa kepastian berakhirnya, mulai menimbulkan hasrat para domba untuk melirik sajian layanan virtual lainnya yang tersedia dari pelbagai gereja, sinode, komunitas Kristen lainnya dengan aneka menu santapan. Hal ini merupakan ujian bagi peran gembala atas kemanusiaan para dombanya yang berpotensi tergiur untuk menikmati rumput tetangga yang nampak lebih hijau. Selain juga para gembala yang tergodai untuk menjadi pengkhotbah favorit dengan sejumlah follower setara public figure umum hingga jerat untuk menggembalakan dirinya sendiri (Yeh 34:2). Metode yang digunakan yaitu riset kualitatif deskripsi dengan meneliti sumber kepustakaan untuk menganalisa aspek-aspek kajian dari teologi pastoral, biblika, hermeneutik, dan trend yang berkembang untuk menemukan hasil yang sesuai tujuan yaitu penggambaran tentang perspektif teologi pastoral dengan kondisi jemaat sebagai domba dalam penderitaan dan kemanusiaannya yang sedang teruji untuk tetap berada dalam kandang yang tercukupi kebutuhan rohaninya.

Authors: Zaluchu Sonny Eli
Published: March 2021

A common problem regarding the method section in the structure of scientific journals is that they are written in general and not typical. A research method must report the procedures the researcher takes to carry out his research. The contents are not the same as the method descriptions in other studies. Therefore, this paper aims to explain the importance of methods in the structure of writing scientific journal articles. In particular, several methods commonly referred to in theological research are presented descriptively and topically. The conclusion obtained is, with the correct understanding of the research method, lecturers or researchers can produce theological research work that can be accounted for its academic validity. Research contribution: This paper provides insights to lecturers and researchers in writing and formulating methods in scientific journal papers and contributing material in writing scientific papers.Permasalahan umum mengenai bagian metode di dalam struktur jurnal ilmiah adalah ditulis secara umum dan tidak khas.

We present a recent Atacama Large Millimeter/submillimeter Array observation of the CO(1−0) line emission in the central galaxy of the Zw 3146 galaxy cluster (z = 0.2906). We also present updated X-ray cavity measurements from archival Chandra observations. The 5 × 1010
M
⊙ supply of molecular gas, which is confined to the central 4 kpc, is marginally resolved into three extensions that are reminiscent of the filaments observed in similar systems. No velocity structure that would be indicative of ordered motion is observed. The three molecular extensions all trail X-ray cavities, and are potentially formed from the condensation of intracluster gas lifted in the wakes of the rising bubbles. Many cycles of feedback would be required to account for the entire molecular gas reservoir. The molecular gas and continuum source are mutually offset by 2.6 kpc, with no detected line emission coincident with the continuum source. It is the molecular gas, not the continuum source, that lies at the gravitational center of the brightest cluster galaxy. As the brightest cluster galaxy contains possible tidal features, the displaced continuum source may correspond to the nucleus of a merging galaxy. We also discuss the possibility that a gravitational wave recoil following a black hole merger may account for the displacement.

Published: March 2021

Les épidémies s’inscrivent dans un imaginaire ancien du fléau et de l’événement catastrophique qui vient bouleverser les sociétés appelant en réponse des mesures drastiques de la part des sociétés et des États. Comme nous le montre Anne Rasmussen, l’épidémie de Covid-19 ne fait pas exception. Cependant, son caractère global intégrant intimement les dimensions sanitaires, sociales, politiques et économiques lui donne une dimension singulière. Elle en fait un moment historique qui vient questionner des principes fondamentaux de l’organisation sociale et politique, à commencer par la valeur que l’on accorde à la vie.
Penser l’État par les plans et les cartes
Authors: Schlimmer Sina
Published: March 2021

Depuis plusieurs années, les Village Land Use Plans sont promus en Tanzanie comme une « meilleure pratique » favorisant des approches dites responsables de l’investissement agricole. Cet article analyse les VLUP comme un instrument d’action publique véhiculant des idées et des intérêts par une pluralité d’acteurs. En proposant une sociohistoire des instruments de planification du foncier en Tanzanie, l’article défend l’argument que ces instruments révèlent différents moments et facettes de la formation étatique en Tanzanie. D’une part, le recadrage et la redéfinition des outils de planification adoptés depuis l’Indépendance reflètent le passage d’un État central socialiste vers un régime politique qui véhicule les principes du libre marché. D’autre part, la fabrique des VLUP dans le cadre des grandes transactions foncières depuis les années 2010 donne à voir de nouvelles formes de déploiement étatique à l’échelle infranationale dans un contexte d’extraversion.
Géopolitique des nuages : enjeux stratégiques et sécuritaires de la modification du temps
Authors: de Guglielmo Marine
Published: March 2021

Au regard de la généralisation des pratiques d’ensemencement de nuages, il semble primordial d’en analyser les enjeux géostratégiques croissants, parmi lesquels, d’abord, leur potentiel d’intensification des tensions géopolitiques. Ces tensions entrent dans le cadre plus large des nouveaux rapports de force qui se structurent autour de la modification de la météo, et notamment des relations commerciales qui apparaissent entre les pays détenteurs et les pays clients de ces techniques. En outre, l’incertitude environnementale qui les entoure laisse présager une multiplication des conflits liés à leur utilisation, et souligne le besoin accru d’un encadrement juridique à l’échelle nationale comme internationale.
Engagement envers le changement et départs volontaires : un test du modèle à trois composantes
Authors: Robert Véronique , Vandenberghe Christian
Published: March 2021

Sur la base du modèle général de l’engagement en contexte de travail de Meyer et Herscovitch (2001), Herscovitch et Meyer (2002) ont proposé un modèle d’engagement envers le changement comprenant les composantes affective, normative, et de continuité. La présente étude prolonge la recherche antérieure sur le modèle à trois composantes de l’engagement envers le changement de deux façons importantes. Premièrement, nous proposons une version révisée de la mesure en trois composantes de l’engagement envers le changement qui inclut des sous-composantes de sacrifice perçu et de manque d’alternatives au sein de l’engagement de continuité, comme cela a été réalisé pour la mesure de l’engagement organisationnel. Deuxièmement, notre étude a examiné comment les composantes de l’engagement envers le changement prédisaient le risque de départ volontaire des employés, un comportement qui ne relève pas des comportements focaux (par exemple, coopération ou soutien actif du changement) associés à l’engagement envers le changement. Ce faisant, nous avons inclus les composantes de l’engagement organisationnel, pour lequel les départs volontaires (versus le maintien à l’emploi) correspondent à un comportement focal. Sur la base d’un échantillon de 602 employés travaillant pour des organisations en situation de changement, nos analyses confirment une structure de l’engagement envers le changement incluant quatre composantes : affective, normative, par sacrifice perçu, et par manque d’alternatives. De plus, les composantes de l’engagement envers l’organisation et envers le changement ont été utilisées comme prédicteurs de la probabilité d’observer des départs volontaires pendant les 6 à 8 mois suivants pour un sous-échantillon de 235 employés. L’engagement organisationnel normatif se révéla être un prédicteur négatif du risque de démission, alors que l’engagement affectif et l’engagement normatif envers le changement augmentaient le risque de démission. Les implications de ces résultats pour la recherche sur l’engagement envers le changement sont discutées.

Published: March 2021

The mode of transit in the current trend is gradually shifting from internal combustion engine operated vehicle to battery operated electric vehicle. The need of electric vehicle began the revolution from traditional gasoline-powered vehicles to electric vehicles (EVs). An electric vehicle uses electric traction motors for propulsion. It could also be powered through a collector system by electricity from off-vehicle sources or could also be self-contained with a battery, solar panels, or an electrical generator to convert fuel to electricity.
The Community of Inquiry Framework, Online and Blended Learning, and the i2Flex Classroom Model
Authors: Swan Karen
Published: March 2021

The community of inquiry (CoI) framework was developed by researchers at the University of Alberta who were interested in exploring the learning that took place among participants in online discussions. Garrison, Anderson, and Archer grounded their thinking in Dewey's progressive epistemology which placed inquiry within a community of learners at the center of the educational experience. The CoI model they created conceptualizes learning in online environments as supported by three interacting presences – social presence, cognitive presence, and teaching presence. This chapter will describe the CoI framework, briefly review research supporting its efficacy in online course design and implementation, and explore how the framework can be applied to blended and online learning environments in general and the i2Flex model in particular.

Authors: Anderson Elizabeth , Avgerinou Maria D. , Dimas Stavi , Robinson Rhonda
Published: March 2021

Visual literacy (VL) is considered among the essential literacies of the 21st century not only due to its significance to most subject areas and fields of knowledge, but also because without it we are the illiterati of today's visually saturated world, suffering any implications that come with this serious void. The chapter discusses the importance of the VL concept in education, and then focuses on illustrating it from the trenches through (a) the design and implementation of a VL course in a pre-service educational technology context presented by two academic colleagues and (b) the personal trajectory of an in-service teacher's experiences and observations in visual literacy within informal and formal educational settings.

Published: March 2021

In the present study, Iron-based FeMnAlNi and Cobalt-based CoNiGa shape-memory alloys (SMA) were processed by laser metal deposition for the first time. The materials show susceptibility to cracking upon processing when unheated substrates are employed. Pre-heating of the substrate materials eliminated cracking completely and enabled robust deposition of thin-wall structures. Microstructural analysis using optical microscopy revealed different microstructural evolution for the two materials considered.
Cellular Automata Analysis of Effects of Substrate Conditions on Microstructure and Texture Evolution during Selected Laser Melting
Authors: Mohebbi Mohammad Sadegh , Illies Oliver , Ploshikhin Vasily
Published: March 2021

A Cellular Automata Finite Difference (CAFD) method was applied to analyze the effects of substrate grain size and texture on the microstructure and texture evolution during additive manufacturing. It was found that the grain size within the substrate is only effective at a short distance. Grains developed from the surrounding powders can lead to an almost similar microstructure away from the substrate. Texture evolution during build-up can be explained by the two main components of {001}<100> and {011}<100>. Development of the former and the latter components can be described by the competitive growth mechanism at the regions beneath and on the sides of the melt-pool, respectively. As a result, the former component is more pronounced at the higher ratios of the melt-pool width to the hatch distance. An almost similar fiber texture can develop from a substrate with the fiber texture of {001}||build-direction (BD). However, a substrate having the fiber {011}||BD evolves into the component {011}<100>, implying that other components of this fiber are not favored. In either case, due to the highly elongated melt-pool, the orientation {001}||hatch-direction (HD) is preferred and {011}||HD is not likely to happen.

Published: March 2021

Ti-6Al-4V is used as a high-performance material in many industries (mainly automotive and aerospace, but also the medical industry) and traditionally produced by hot forging, with subsequent extensive post-processing and machining, leading to a material yield far from 100 % [1]. New production chains, such as additive manufacturing, enable the near net shape production of high-performance parts, however, still with long production cycles and high manufacturing costs, especially for larger parts [2]. Therefore, an efficient and feasible production is often limited to low quantities and/or small pieces. In the present study, we propose a hybrid manufacturing route, combining additive laser metal deposition (powder LMD) on hot forged base components, enhancing material efficiency, but still enabling the production of industrial quantities. Primary investigations on the microstructure and mechanical properties of the material show results similar to conventional hot forged material, but reduce the number of processing steps and increase the material yield.In more detail, the relationship between the primary beta grain size and the secondary alpha phase characteristics was investigated and moreover, related to the cooling history of the material. Furthermore, the influence of the microstructure and phase characteristics on the mechanical properties of the material was analyzed. For the determination of the primary beta grain size, the programming language MATLAB as well as its integrated open-source toolbox MTEX were used, where a GUI has been developed for the reconstruction of the primary beta grain orientations and sizes from recorded EBSD data of the secondary alpha (Ti) phase, using the Burger’s orientation relationship (BOR, [3-7]).

Published: March 2021

Pervious concrete pavement is a porous urban surface. It could reduce runoff capacity, decrease a storm-water detention, reduce the amount of requiring rain drainage pipes, and let rainwater filter into ground and allow groundwater resources to renew in time. Fire damage, could be one of important factors since European countries have been used pervious concrete in buildings construction. This study was conducted to assess the fire damage on pervious concrete with silica fume and steel fiber. The test results find that pervious concrete with 10% silica fume and 2% steel fibers showed the maximum increase in compressive and flexural strengths by 60% and 23% respectively over the control mix while maintaining adequate permeability. It also shows that the flexural strength of pervious concrete with 10% silica fume and 2% steel fiber could reach 45 kg/cm2strength specification. The high temperature exposure results find that pervious concrete could hardly be detected any crack at the temperature of 700 °Cor 800°C and fire duration of 2 hours. There is some damage on strength after the fire-attack test, the ratio of the residual strength can range from about 20%~60% and it depends on temperature, steel fiber, and silica fume content. By this study of pervious concrete will be valuable for fire safety design and construction of practice.

An increase in power consumption density is related to the internal thermal characteristics of an electronic device, and the heat dissipation of the device is directly related to the high performance and miniaturization of the device. TIM (thermal interface material) with excellent internal heat dissipation performance are mainly used to improve the heat dissipation performance of electronic devices. Recently, the need for a high-efficiency TIM with high-performance thermal conductivity and low thermal contact resistance has increased. In this study, thermal grease was prepared by mixing Cu-Ni nanopowders with silicon oil, the thermal grease was then used as a heat transfer material. Compared to silicone thermal grease, the thermal conductivity of all prepared samples was excellent. In particularly, thermal conductivity was improved by about maximum 212% compared to that of thermal silicone of thermal grease mixed with Cu-Ni powder.

As a vital male accessory reproductive gonad, the prostate requires vascular endothelial growth factors for promoting its growth and development. In this study, we investigated the localizations and expressions of vascular endothelial growth factor (VEGF) and its receptors including VEGF-receptor1 (VEFGR1) and VEGF-receptor2 (VEGFR2) in the prostate of the wild ground squirrels during the breeding and the non-breeding seasons. The values of total prostate weight and volume in the breeding season were higher than those in the non-breeding season. Histological observations showed that the exocrine lumens of the prostate expanded in the breeding season and contracted in the non-breeding season. The mRNA expression levels of VEGF and VEGFR2 in the prostate were higher in the breeding season than those in the non-breeding season, but the mRNA expression level of VEGFR1 had no significant change between the breeding and non-breeding seasons. Immunohistochemical results revealed that VEGF, VEGFR1 and VEGFR2 were presented in epithelial and stromal cells during the breeding and non-breeding seasons. In addition, the microvessels of the prostate were widely distributed and the number of microvessels increased obviously in the breeding season, while decreased sharply in the non-breeding season. These results suggested that expression levels of VEGF and VEGFR2 might be correlated with seasonal changes in morphology and functions of the prostate, and VEGF might serve as pivotal regulators to affect seasonal changes in the prostate functions of the wild male ground squirrels via an autocrine/paracrine pathway.

Published: March 2021

Background

Studies have shown that public awareness of ovarian cancer is weak, and women are often diagnosed at late stages when treatment is difficult. This study aimed to determine the barriers for seeking early medical care and level of knowledge and awareness among women regarding ovarian cancer.

Design and methods

A structured questionnaire was designed and adapted from the validated cancer awareness measure.

Results

The recognition level of ovarian cancer symptoms among women in this study varied from 12-51%, and the most alarming ones, back pain, eating difficulties, and persistent abdominal pain, were missed by most of the surveyed women. The most recognized ovarian cancer risk factors were never being pregnant, having a history of infertility, and going through menopause, while the least recognized was having personal or family history of breast cancer. Non-UAE nationals women with higher educational levels had better knowledge of ovarian cancer compared to their peers.

Conclusions

A change or implementation model is highly recommended in order to improve women's awareness of ovarian cancer symptoms. Strengthening education among women with regards to risk factors, early symptoms, and the need to seek early medical help should help to increase ovarian cancer awareness and reduce a delay in the diagnosis.

Sensory Brain Responses and Lateralization in Nonpainful Tactile Stimuli during Sleep
Authors: Inanç Gonca , Özgören Murat , Öniz Adile
Published: March 2021

Aims and Objectives:

The aim of this study was to investigate the difference between sensory brain responses of nonpainful tactile stimuli applied to the fingers of the right-hand dominant individuals between the hemispheres. Materials and

Methods:

Nineteen healthy volunteers (9 women, mean age ± standard deviation: 23.00 ± 2.24 years) participated in the study. Electroencephalogram (EEG) recordings were taken from 40 channels polysomnography system. A uniform nonpainful stimulus was applied to two fingers (index and middle fingers) of the right and left hand with a pneumatic stimulator unit.

Results:

Non-rapid eye movement sleep (NREM) whole night sleep-related potentials were evaluated. When the stimulus was applied to the right hand, central and parietal regions of the P50 response component appeared significantly earlier in the left hemisphere. When the left-hand stimulus was applied, the P50 and N100 response components appeared significantly early in central, parietal, and temporal regions in the left hemisphere. Hence, amplitudes of the right-hand response components (P50 and N100) were found to be greater in the central, parietal, and temporal regions in the left hemisphere. When the stimulus is applied to the left hand, the amplitude of the P50 component was greater in the central and temporal regions in the left hemisphere.

Conclusion:

P50 and N100 are components related to sensory processing. The difference in latency and amplitude observed in these components between hemispheres indicates the presence of lateralization in sensory processing during sleep.
The Effect of Vision on Top-Down Modulation of Hand Blink Reflex
Authors: Çalikusu Fatma Zehra , Gündüz Ayşegül , Kızıltan Meral
Published: March 2021

Objective:

The magnitude of hand blink reflex (HBR) increases when a threatening stimulus is positioned in the peripersonal space (PPS) compared with stimulus in the extrapersonal space (EPS). We hypothesized that the reflex increase in PPS might change depending on whether the stimulus was seen. We aimed to investigate the alterations in HBR response to understand the effects of vision on cortical modulation of HBR.

Methods:

The HBR was recorded from 11 healthy volunteers while the hand was far away from the face (EPS), close to the face with eyes open (PPS-eyes open), and close to the face with eyes closed (PPS-eyes closed). Changes in the response magnitudes were compared between the three conditions.

Results:

HBR was obtained in all subjects. As expected, there was an increase in the reflex magnitude in the PPS-eyes open condition relative to EPS. In the PPS-eyes closed condition, the duration and latency were shorter and the area under the curve was significantly smaller compared with the PPS-eyes open condition.

Conclusion:

The enhancement of HBR in PPS is attributed to tonic top-down modulation. Our study provides evidence for the special sensory modulation of the PPS effect on HBR and may suggest cortical modulation of top-down modulation of brainstem neural circuits.

Published: March 2021

Objectives:

Chronic tension-type headache (TTH) is a serious disease that disrupts quality of life. In this study, the effect of prophylactic oral melatonin treatment on headache and cerebral vasomotor reactivity (VMR) was investigated in patients diagnosed with chronic TTH per the International Classification of Headache Disorders criteria.

Subjects and Methods:

Twenty patients with chronic TTH and 20 healthy individuals were included in the study. The patients were administered a melatonin treatment at 3 mg/day for 12 weeks. The number of monthly painful days and pain severity were recorded with the “Visual Analog Scale” before and after the treatment. Cerebral VMR measurements were performed at baseline in the control group and in patients before and after the treatment.

Results:

The median number of monthly painful days was 20 (15–27) before the treatment and 10 (4–18) after the treatment; the median pain severity score was 70.00 (45–80) before the treatment and 42.50 (15–75) after the treatment. The difference was statistically significant (P = 0.001). No statistically significant difference between the VMR values was observed (P > 0.05).

Conclusions:

Melatonin treatment was effective in reducing the pain severity and decreasing the number of monthly painful days in patients with chronic TTH but demonstrated no effect on the cerebral VMR.
The Use of Botulinum Toxin as an Adjunct in the Treatment of Severe Congenital Unilateral Upper Limb Muscular Hypertrophy
Authors: Üstün Galip Gencay , Firat Tüzün , Çetin Alp , Aksu Ali Emre
Published: March 2021

Congenital unilateral upper limb muscular hypertrophy is a rather new entity. Patients have unbalanced muscular forces on their upper extremities due to muscular hypertrophy. These unbalanced forces preclude physiological movements, and in the late course, cause joint deformities. Once joint deformities occur, benefit from surgery diminishes; botulinum toxin can be used for the prediction of a possible benefit from surgery. A 14-year-old girl presented with flexion and ulnar deviation contracture of the left wrist, narrowing of the first web space, flexion contracture of all fingers, and more evident on the first, third, and fourth fingers. After botulinum toxin injection, the most notable benefit was seen on the wrist contracture. In surgery, adductor myotomy, flexor carpi ulnaris transfer to palmar aponeurosis, and tendon transfers of flexor digitorum superficialis to flexor digitorum profundus in the third, fourth, and fifth fingers were made. The postoperative gain was similar to the outcome after botulinum toxin injection. Botulinum toxin may help the surgeon to understand if chronic joint deformities have occurred and predict possible benefit from surgery.
