Published: January 2024

Cette contribution est le prolongement d’une précédente publication1 portant sur l’usage de la particitation dans le discours protestataire des manifestants algériens lors du mouvement populaire du 22 février 2019. Cette présente étude va reprendre le concept de particitation initié par Maingueneau, tout en considérant le langage numérique comme le thésaurus qui nourrit en arrière-plan le discours militant dans les slogans des jeunes manifestants. Ainsi, et à travers une étude sociolinguistique, énonciative et pragmatique ; nous allons montrer que l’usage du code informatique dans ces énoncés ne serait pas seulement l’expression d’une quête de reconnaissance d’une catégorie sociale, mais un nouveau moyen de mobilisation,
Walking pain-free: A prospective study on the efficacy of surgical resection with Achilles tendon reinforcement for painful Haglund lesions
Authors: Toreih Ahmed A , Abdelbadie Ahmed , El-Adawy Moawed F 
Published: January 2024

Abstract

Background
Haglund’s deformity is a common cause of posterior heel pain, often requiring surgical management when conservative treatment fails. Traditionally, surgery focused solely on resection of the bony prominence, yielding suboptimal outcomes.

Aim
This study assessed the efficacy of surgical resection of painful Haglund lesions combined with Achilles tendon reinforcement for managing insertional Achilles tendinitis.

Methods
Twenty patients with insertional Achilles tendinitis underwent surgical resection of Haglund lesions and Achilles tendon reinforcement with suture anchors. Functional outcomes were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score preoperatively and at 6 and 12 months postoperatively. Complications were recorded.

Results
The mean AOFAS score significantly improved from 43.5 ± 7.2 preoperatively to 79.0 ± 9.1 at 6 months and 84.5 ± 9.8 at 12 months postoperatively (P<0.001). Early weight-bearing was achieved in 2 weeks. The complication rate was 25% (all minor). There were no re-ruptures or revisions during the one-year follow-up.

Conclusion
Surgical resection combined with Achilles tendon reinforcement is an effective treatment for Haglund’s deformity, allowing early weight-bearing while significantly improving function. It is associated with a low complication rate and no major adverse events. This technique addresses both bony and soft tissue pathologies, optimizing outcomes.

Authors: Elkhateeb Tameem M , Zahlawy Hany EL , Hussien Mohammed A 
Published: January 2024

Abstract

Purpose
To assess the clinical and radiological outcomes of patients experiencing fusion technique by unilateral versus bilateral instrumentation with interbody lumbar fusion.

Materials and methods
Fifty-nine patients were included in this study. Thirty-six patients were managed with bilateral PSF and interbody fusion, and 23 had unilateral PSF and interbody fusion. Clinically, the patients were evaluated using the mJOA score. They were followed up for a minimum period of 3 years. Fusion at follow-up was established using radiographs.

Results
Procedure periods were quicker, and blood loss was fewer in the unilateral group. Fusion rates were comparable in both groups with insignificant differences. There was a statistically significant difference in clinical improvement of JOA scores in both groups.

Conclusion
Unilateral pedicle screw fixation together with interbody fusion is an efficient choice in chosen cases. Prospective, randomized research with a higher number of cases and longer follow-up times is required for more consistent outcomes.

Authors: Mostafa Ahmed G , Abdelkhalik Waleed S , Abd El Fatah Karim A , Hassaan Ahmed M 
Published: January 2024

Abstract

Background
Pediatric Flexible flat foot is the prevalent type of flat foot. Conservative measures are the first line of treatment. However, surgery may be required in some cases.

Objective
To compare outcomes of lateral calcaneal lengthening osteotomy versus subtalar arthroereisis for the pediatric flexible flat foot.

Methods
Calcaneal lengthening osteotomy was operated on 25 feet and subtalar arthroereisis was operated on 19 feet. Patients were evaluated preoperative and postoperative according to the American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, Meary’s angle and Talonavicular coverage angle. The follow-up duration was 18 months.

Results
Lateral calcaneal lengthening osteotomy showed better clinical and radiological outcome versus subtalar arthroereisis. In LCL group,American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score (68.2 ± 1.45 preoperative to 98 ± 5 postoperative) and Talonavicular coverage angle (18.8 ± 5.6 preoperative to 3.96 ± 2.46 postoperative) improved versus SA group, the AFOAS (68.62 ± 2.93 preoperative to 96.55 ± 3.48 postoperative) and Talonavicular coverage angle (23.98 ± 5.88 preoperative to 5.94 ± 4.59 postoperative) respectively. Significant difference was found postoperative between the two groups regarding Meary’s angle, in LCL group improved from 17 ± 5.04 preoperative to 4.44 ± 1.66 postoperative while in SA group the angle improved from 23.62 ± 7.74 preoperative to 2.98 ± 1.27 postoperative.

Conclusion
Calcaneal lengthening osteotomy achieved more improvement in AOFAS score than subtalar arthroereisis group with better clinical and radiological outcomes but subtalar arthroereisis is less invasive procedure with early weight bearing and mobilization.
Comparison between magnetic resonance imaging and intraoperative arthrogram in detection of soft tissue obstacles to reduction in developmental dysplasia of the hip
Authors: Youssef Amin A-R , Mosa Mena M , Elsharkawi Karim M , Barakat Mohamed S , Farahat Ali A K , Bastawi Rim A 
Published: January 2024

Abstract

Background
The spectrum of abnormalities in developmental dysplasia of the hips (DDH) is not limited to osseous changes, but extends to include periarticular soft tissue changes, which could not be visualized by conventional radiographs or computed tomography (CT). Both MRI and conventional arthrogram can evaluate those soft tissue obstacles to reduction.

Patients and methods
In total, 16 children with DDH (21 hips), dated for surgical management by open reduction, were chosen. All patients were examined by preoperative MRI as well as intraoperative arthrogram. Both modalities were used to assess different obstacles to reduction, such as the labrum, pulvinar, ligamentum teres (LT), iliopsoas tendon interposition, and the transverse acetabular ligament (TAL).

Results
Both MRI and conventional arthrogram showed similar sensitivity (100%) for detection of ligamentum teres pathology, labral inversion, and hypertrophied pulvinar. MRI showed higher sensitivity than arthrogram for detection of the iliopsoas tendon interposition (100% vs. 64.5%) and for detection of the thickened transverse acetabular ligament (85.7% vs. 19%).

Conclusions
Both MRI and conventional arthrogram can visualize the soft tissue obstacles to reduction in dysplastic hips. MRI is a noninvasive technique, requiring sedation in the pediatric population. Conventional arthrogram is an invasive technique. However, significant complications can be readily avoided.

Published: January 2024

Abstract

Introduction
Percutaneous pinning of supracondylar humerus fracture(SCHF) in children is an effective way to maintain the anatomic reduction of a displaced. closed reduction and percutaneous pinning (CRPP) had been considered the standard treatment for displaced SCHF in children.

Patients and methods
A prospective case series, was conducted at the emergency department of Helwan university hospital from February 2020 to September 2021. It includes 40 patients with Gartland type III fracture who presented to the orthopaedic casualty and were included in the study. Four patients (10%) had the transolecranon wire was directed intramedullary, 11 patients (27%) had the wire directed posterolaterally, and 16 patients (40%) had the wire directed posteromedially and 9 patients (23%) had the wire directed posteriorly.

Results
The mean age was 5.57 years (range from 2–12 years). The mean Baumann angle in the patients was (70.89 ± 2.40). The mean follow-up duration was 3 months (range from 3–3.2 months). with mean carrying angle was about (9.37 ± 2.52) and no one of the patients had an excessive deformity of carrying angle that required correction. Regarding ROM loss, there were 25, but always poor. A few complications occurred including pin tract infection and broken transolecranon wire and all were tolerable with no effect on the outcome.

Conclusion
The Transolecranon and lateral Kirschner wires fixation is an effective option that provides good stability with the little number of trials in the management of supracondylar fracture of the humerus in children, and the risk of nerve injury or fishtail deformity was avoided especially in the hands of junior trainees in their first 3 years of training.

Published: January 2024

Abstract
Non union after intramedullary nail fixation is difficult to treat. Many options are available for its management including nail exchange, bone graft while keeping the nail, nail removal and plating. Each method has its advantages and disadvantages. The aim of this study is to evaluate the results of management of tibial non union after intramedullary fixation using plate augmentation. Between January 2012 and December 2019, thirty four patients with nonunited fracture tibia previously treated with locked intramedullary nails were included in this study. The ages of patients ranged from 20 to 62 years ( an average age: 43 years). All patients were diagnosed to have aseptic nonunion. All patients achived bony union except 2. Bone union was achieved in a time ranged from 3 to 9 months (an average time 5 months). The average limb length discrepancy was 1 cm ( range 0 to 1.5 cm ). The reported complications were superficial wound infection in 2 cases, joint stiffness in 3 patients and nonunion in 2 cases. There were no intraoperative complications. All patients reported no pain at the fracture site during weight bearing at the final follow-up. We concluded that augmentation plate fixation is a good option for treatment of tibial nonunion after intramedullary nail.

Authors: Subramanian Shalini , Shetty Deepa , Dudeja Gagan , Das Priyanka 
Published: January 2024

Background and Aims:
Inhalational technique is used to induce anaesthesia in children without intravenous access. We aimed to determine the median effective dose (ED50) of intranasal dexmedetomidine to ensure satisfactory mask acceptance during inhalation induction in children with retinoblastoma undergoing examination under anaesthesia.

Methods:
A prospective sequential allocation study was conducted in children aged 1–60 months divided into Group A (1–18 months) and Group B (18–60 months). Children were administered dexmedetomidine intranasally as premedication. Sedation was assessed using the modified Observer Assessment of Alertness and Sedation Scale until induction. Successful mask acceptance was defined as a cooperative or asleep child during inhalational induction. The starting dose of dexmedetomidine was 1 µg/kg. The next dose varied by 0.2 µg/kg depending on the outcome of this case. According to the Dixon up-and-down method, the mean of midpoints of the failure–success sequence was calculated to obtain the ED50 values.

Results:
The ED50 of intranasal dexmedetomidine for satisfactory mask acceptance was 0.7 µg/kg (95% confidence interval [CI]: 0.54–0.86) in Group A (n = 23) and 0.96 µg/kg (95% CI: 0.83–1.08) in Group B (n = 25) (P = 0.020). The mean (standard deviation) duration of anaesthesia was 33.5 (14.9) minutes in group A versus 23.5 (8.48) minutes in Group B (P = 0.007).

Conclusion:
ED50 was lower in children younger than 18 months than in older children. There was no difference in the time to discharge from the post-anaesthesia care unit despite the procedure being longer in smaller children.

Authors: Sassi Kaissar , Tardif Elsa , Lasry Louis , Manenc Lola , Guerby Paul , Minville Vincent 
Published: January 2024

Background and Aims:
Pregnancy presents risks, particularly for women with pre-existing health problems. Pre-anaesthetic consultations can help anticipate these risks and establish a medical management strategy on the delivery day. While teleconsultations gained popularity during the coronavirus disease 2019 (COVID-19) pandemic, research on pre-anaesthetic teleconsultations during pregnancy is limited. This study aimed to assess patient satisfaction and physician perception of teleconsultations for third-trimester pre-anaesthetic consultations.

Methods:
A prospective observational study included pregnant women who opted for teleconsultations for pre-anaesthetic consultations. Patient satisfaction was assessed using Likert scale questions and the System Use Scale. Anaesthetist satisfaction was evaluated using a Likert scale and by considering changes in anaesthetic techniques and missing clinical data in the pre-anaesthetic assessment. Data analysis utilised SPSS Statistics for Windows, Version 20.0. encompassing descriptive statistics, hypothesis testing and odds ratio calculations. This approach explored the correlation between patient and anaesthetist satisfaction and pertinent risk factors.

Results:
The study enroled 99 patients, with 85% expressing satisfaction and high satisfaction on the Likert scale and 88% finding the teleconsultation acceptable based on the System Use Scale (score ≥ 70). Anaesthetists reported being satisfied with the pre-anaesthetic consultations in 94% of cases.

Conclusion:
This study demonstrates the feasibility and effectiveness of telemedicine consultations in obstetric anaesthesia, showing high patient and anaesthetist satisfaction rates.
Comparative evaluation of nebulised dexmedetomidine vs fentanyl for the treatment of post-dural puncture headache (PDPH) in parturients after caesarean section under spinal anaesthesia: A randomised controlled study
Authors: Kumar Amarjeet , Sinha Chandni , Singh Kunal , Anant Monika , Kumar Ajeet , Kumari Poonam 
Published: January 2024

Background and Aims:
The incidence of post-dural puncture headache (PDPH) following spinal anaesthesia in the obstetric population is around 0.5%–2%. Hydration, bed rest, caffeine, paracetamol, non-steroid anti-inflammatory drugs, epidural blood patches, etc., are the various modalities used for its management. This study aims to compare nebulised dexmedetomidine versus fentanyl for the treatment of PDPH in parturients after caesarean section under spinal anaesthesia.

Methods:
Ninety obstetric patients aged 18–35 years with American Society of Anesthesiologists (ASA) physical status II/III and suffering from PDPH as per the criteria of the International Headache Society after caesarean section under spinal anaesthesia were recruited in this double-blinded randomised study. Patients were randomised to Group D (dexmedetomidine 1 µg/kg nebulisation), Group F (fentanyl 1 µg/kg nebulisation), and Group S (saline nebulisation 4mL). The nebulisation was done 12 hourly for 72 hours. Assessment parameters included pain score and the requirement of additional treatment such as paracetamol, caffeine, and epidural blood patch. Analysis of variance test was used for continuous quantitative variables, and the Kruskal–Wallis test was used for quantitative discrete data.

Results:
The pain scores at 1, 6, 12, 24, 48, and 72 hours following nebulisation were significantly lower in Group D in comparison to groups F and S (P < 0.001). The number of patients requiring additional analgesic therapy was lower in Group D in comparison to patients in other groups (P < 0.001).

Conclusion:
Dexmedetomidine nebulisation resulted in effective reduction in PDPH symptoms and pain scores. Nebulisation with fentanyl did not alleviate PDPH symptoms when compared to the control group.
Single‐shot phase‐shifting on Michelson interferometry for incoherent digital holography
Authors: Hong Keehoon , Choi Kihong 
Published: January 2024

AbstractA single‐shot phase‐shifting method in incoherent digital holography (IDH) based on Michelson interferometry is proposed herein. The proposed method uses polarization‐modulating optical elements and a polarization sensor in the Michelson interferometer optics to induce a geometric phase shift. It acquires four holograms with different geometric phase retardations in a single exposure to eliminate the bias and conjugate noise using a phase‐shifting technique. The proposed optical system enables real‐time bias and conjugate term removal from a recorded hologram without requiring sequential recording for phase shifting. Furthermore, because it is based on Michelson interferometry, it can be implemented using simple reflective optics without expensive or difficult‐to‐produce optical elements for single‐shot phase shifting. The principles of self‐interference and geometric phase shifting in the proposed optical structure were analyzed mathematically. A real‐time IDH‐recording experimental setup was constructed to verify the proposed method. The experimental results of single‐shot phase‐shifting IDH and hologram movie recordings confirm the feasibility of the proposed method.
Límites del derecho a huelga en los servicios públicos
Authors: Castro Medina Raquel 
Published: January 2024

En el contexto del derecho de huelga en España, se evidencia su arraigo constitucional como un medio fundamental para la protección de los intereses laborales, siendo reconocido como un derecho subjetivo, constitucional, fundamental e inalienable. No obstante, a pesar de su importancia, la regulación actual presenta desafíos notables. La falta de una legislación específica para funcionarios públicos, a pesar de su reconocimiento expreso en el Estatuto Básico del Empleado Público (EBEP), genera un vacío normativo que requiere atención inmediata. La carencia de límites claros y condiciones específicas para el ejercicio del derecho de huelga por parte de los funcionarios públicos añade complejidad a la situación. Mientras el EBEP reconoce expresamente este derecho, la ausencia de una normativa detallada deja interrogantes sobre aspectos cruciales como los procedimientos de convocatoria y tramitación, así como las excepciones y limitaciones aplicables a este colectivo.
La urgencia de abordar esta falta de legislación específica se fundamenta en la necesidad de garantizar un ejercicio equitativo del derecho de huelga por parte de los funcionarios públicos. La claridad normativa en cuanto a los límites y condiciones permitirá una aplicación más coherente y justa de este derecho fundamental, armonizando así las dinámicas laborales en el ámbito público con los principios constitucionales que rigen el derecho de huelga. Este llamado a la acción legislativa pretende superar las complejidades actuales y consolidar un marco normativo robusto que asegure tanto la protección del derecho fundamental como el funcionamiento efectivo de los servicios públicos esenciales.

The coronavirus 2019 (COVID-19) pandemic resulted in widespread isolation, with hospitalized patients and healthcare workers (HCWs) bearing the physical and emotional brunt of patient loneliness. While music has well-documented therapeutic effects in reducing depression, anxiety, and stress in patients and HCWs, in-person performances were not possible during the pandemic. In response, Virtual Bedside Concerts (VBC) was created to provide interactive virtual music to patients during this time of isolation. Volunteer coordinators (VCs) work with HCWs at healthcare facilities to pair musician volunteers with interested patients. Over the first 15 months, VBC hosted 209 concerts performed by 66 volunteer musicians at 5 different healthcare facilities. Anonymous feedback surveys indicate that patients, musicians, and HCWs value the opportunity for music to complement traditional medical care and provide musical healing and a sense of community and connection. VBC has been widely successful in demonstrating how interactive virtual music may provide an unprecedented level of social. Facilitating social bonds through music has improved the rapport between HCWs and patients, supplemented traditional medical care, and brought a more humanistic experience to healthcare settings. Our framework may be used at other institutions to provide musical healing and a sense of community throughout and beyond the pandemic.
