« Si on fouillait dans les cartons des photographes » : désir et défis de la collection photographique au Muséum national d’histoire naturelle (1840-1880)
Authors: Lafontaine Lisa 
Published: December 2023

Si l’histoire des collections naturalistes connaît un renouveau historiographique, la place que la photographie a pu occuper dans les laboratoires du Muséum, au cœur du travail des naturalistes, est relativement peu connue. Nous aborderons d’abord l’ambition, développée tôt par ces savants, de former des collections photographiques, inscrivant ce nouveau médium dans une démarche collectionniste caractéristique du processus scientifique des sciences naturelles. Nous évoquerons ensuite les premiers projets esquissés dans ce sens par divers acteurs du Muséum, ainsi que les freins et limites qui ont parfois contrarié leur désir de collectionner ces images. Nous aborderons enfin la profonde mutation, du classement à la numérisation, que connaissent aujourd’hui ces images. Leur nouveau statut patrimonial représente l’aboutissement d’un enjeu au long cours : celui de la mise au service du bien commun des collections naturalistes.
Le fonds photographique sur Pompéi et Herculanum d’Adolf Michaelis à l’Université de Strasbourg : premières approches sur les usages, l’histoire et la valorisation d’une collection au service de la pédagogie
Authors: Acolat Delphine 
Published: December 2023

Le fonds Adolf Michaelis, du nom du professeur d’histoire de l’art et d’archéologie classique qui a commencé à le constituer dans les années 1860 jusqu’en 1907, conservé à l’Université de Strasbourg, comprend un fonds photographique sur Pompéi, tripartite, composé d’une collection de tirages sur papier privée, d’une collection de l’Institut d’archéologie et d’une collection de plaques de verre de projection. L’ensemble, déjà partiellement valorisé par une numérisation, permet d’étudier la constitution et l’évolution d’une collection à but universitaire de recherche et d’enseignement, et d’en montrer la valeur patrimoniale.
Aperçus sur les images publicitaires destinées aux enfants à la fin du xixe et au début du xxe siècle
Authors: Robin Christian 
Published: December 2023

Les chromos publicitaires, depuis la fin du xixe siècle, font l’objet de collections qui, semble-t-il, sont restées beaucoup plus dans le domaine privé que dans les ressources de conservation publique. Ils rivalisent du reste avec les cartes postales dans le circuit des échanges entre particuliers. Si la fragilité matérielle de ces images, comme leur relative rareté, les rendent difficiles à consulter, les sites d’internet, parfois assurés par les grandes marques, comblent ce déficit. Ils ne sont pas nombreux à avoir attiré l’attention sur ce patrimoine qui a été indissociable d’une « culture moyenne ». Même si des artistes prestigieux ont signé de modestes primes distribuées à un jeune public, l’anonymat du dessinateur règne dans ces images qui ne manquent pas de qualités esthétiques. Elles font preuve d’une variété de formes remarquable d’invention, et leurs sujets, multiples, nous renseignent sur une société qui mettait déjà l’enfant au centre de ses préoccupations pédagogiques et économiques.
L’apprentissage de la taille du silex sur le site aurignacien de Bourg-Charente (Charente, France) : interactions cognitives et implications sociétales
Authors: Connet Nelly , Bertran Pascal , Claud Émilie , Larmignat Blandine , Boitard Ève 
Published: December 2023

Résumé. Le site de Bourg-Charente est un site stratifié de plein air occupant un versant calcaire en rive gauche de la Charente (France). Le niveau aurignacien, objet du présent article, est conservé sur une surface de 1 000 m2 et comprend 12 concentrations de vestiges lithiques qui représentent autant de postes de taille. Les analyses taphonomiques et dynamiques (dont remontages de silex taillés), préalable indispensable à l’analyse palethnologique proposée, permettent de mettre en synchronie sept d’entre eux. Les restes osseux ne sont pas conservés, mais l’analyse fonctionnelle réalisée sur les restes lithiques taillés permet d’identifier des aires d’activités spécifiques avec, d’une part des activités de boucherie en découpe réalisées en parallèle d’activités de taille du silex et, d’autre part des activités de raclage requérant des outils produits de façon anticipée. Une des concentrations de vestiges correspond à une aire d’apprentissage de taille du silex. Distincte des autres zones d’activités tout en en étant peu éloignée, elle entretient avec celles-ci les liaisons physiques qui témoignent d’interactions entre apprenants et tailleurs aguerris/tuteurs. Les relations observées entre ces zones permettent de proposer que les exercices de taille ont eu pour principal objectif l’acquisition et la maîtrise des gestes prévalant au détachement d’éclats.
Questionner en classe le texte littéraire du point de vue du droit : une motivation pour la lecture littéraire ?
Authors: Mas Marion 
Published: December 2023

Cet article cherche à mettre en relief l’intérêt des approches théoriques du mouvement « droit et littérature » dans le cadre de l’enseignement de la lecture littéraire. D’une part, l’analyse s’appuie sur les travaux de Martha Nussbaum et de François Ost, considérant la littérature comme un espace privilégié d’exercice du jugement pratique ; d’autre part, elle mobilise la « critique judiciaire » de Caroline Julliot, qui, dans le prolongement de la « critique policière » de Pierre Bayard, s’attache à juger ou à rejuger les personnages de fiction, en dressant leur « instruction » à partir d’une lecture approfondie du texte. Ces démarches, qui invitent à postuler une analogie entre l’acte de lecture et l’opération de jugement, conduisent à questionner l’acte de lecture et, à l’issue de l’observation d’une séquence menée dans deux classes, à proposer un dispositif didactique à trois dimensions (reposant sur la fiction du rôle de juge, le débat interprétatif et la contextualisation), visant un décentrement du sujet lecteur, en vue d’un retour approfondi au texte et du développement de compétences lectorales et interprétatives spécifiques.
Role of growth modulation in the management of idiopathic scoliosis: A narrative review of literature
Authors: Prabhavi R.P. Umanda , Amarasekera Hiran 
Published: December 2023

Scoliosis is a condition in which there is a lateral curve to the spine. The cause of scoliosis is unknown, but different aetiologies have been suggested, but mostly cause has been idiopathic in nature. Muscle spasms, cerebral palsy, Marfan syndrome, and tumours (neurofibromatosis) are some of the suggested aetiologies. Progressive adolescent idiopathic scoliosis (AIS) affects mainly girls and anterior spinal overgrowth during the second growth spurt appear to be a significant cause. The diagnosis of scoliosis is primarily a clinical suspicion followed by an AP and lateral X ray of spine in standing position. Measurement of the Cobb angle is the standard method of assessing the curvature in a quantitative manner. It is the angle between two lines, drawn perpendicular to the upper endplate of the first vertebra involved and the lower endplate of the last vertebra involved. Cobb angles are followed for both curves for those with two curves. Risser classification grades the skeletal maturity on X rays and is considered along with the Cobb angle to making a decision towards surgery. Indications for surgical correction of scoliosis is not clearly defined however, the treatment of scoliosis is based on the severity and progressive nature of the curve. Cobb angle above 40 degrees, rapidly progressing curve, major thoracic deformity affecting the function such as breathing and cosmetic reasons, are some of the indications for surgery. There are several modalities of surgical correction. Main method has been correction of the deformity and fixation with one or two rods and pedicle screws followed by bone grafting. Harrington rods were the primarily used system, but with time many spinal instrumentation systems and rods have been introduced to the market. Apart from using rods some have tried anterior vertebral body stapling and anterior vertebral body tethering for correction scoliosis using the principle of growth modulation.
We conducted a systematic review to answer the question, 'What is the role of growth modulation in the management of idiopathic scoliosis?' All articles / publications published from 2010 May to 2019 October were used as research data. A health, related database (PubMed) was used for the search. Search criteria revealed 99 articles initially and 37 articles after filtered based on title reading. Then 18 articles were selected for the final analysis after being filtered manually by reading summary and abstracts of each article.
Laparoscopic versus open appendectomy in the management of chronic appendicitis
Authors: Abdelgawaad Moamen S. , Elnabi Abd Elrazik Mahmoud H. , Badee Mena H. , Sobhy Ragai 
Published: December 2023

Background
The term ‘chronic appendicitis’ (CA) is still clearly undefined. However, once established, it necessitates appendectomy, which could be performed via open or laparoscopic approaches. Comparisons between the two approaches have been made in acute appendicitis cases, with no previous trials including CA patients. That is why we conducted this study to compare these two approaches in the management of CA patients.

Methodology
50 CA were included in our prospective trial, and they were randomly assigned into two groups; the OA group (25 open appendectomy patients) and the LA group (25 laparoscopic appendectomy cases).

Results
The statistical analysis revealed no significant differences between the two groups regarding most preoperative characteristics. The laparoscopic approach was associated with significant prolongation in operative time that had an average of 1 h in the LA group, while it ranged between 0.5 and 1 h in the OA group (P = 0.005). Nonetheless, laparoscopy led to a significantly better postoperative recovery profile, manifested in the shorter hospitalization period (1 vs. 2 days in the open approach) and less postoperative pain (all patients with mild pain compared with moderate pain in the open group). Only 2 (8%) casesexperienced temporary vomiting in the OA group.

Conclusion
Laparoscopy is superior to the open approach in the management of chronic appendicitis patients. It is associated with a better analgesic profile, a shorter hospitalization period, and a better chance of detecting other concomitant intraabdominal pathologies. However, the increased operative time should be considered.
Tricuspid annuloplasty using autologous pericardial strip versus conventional suture annuloplasty (the De Vega and Kay methods) for repair of functional tricuspid regurgitation
Authors: Helmy Ahmed , Elkariem Mohsen A. , Moftah Hassan , Elnahas Yasser , Elkader Amr M. A. 
Published: December 2023

Background
Tricuspid regurgitation (TR) is a common sequelae associated with left-sided heart valve diseases due to right ventricular and tricuspid annular dilatations. Surgical repair for significant TR has been demonstrated to enhance patient outcomes and lower mortality rates.

Aim
The primary endpoint is to evaluate the short-term outcomes of tricuspid annuloplasty employing a flexible band of autologous pericardium compared with the traditional suture annuloplasty procedures.

Patients and methods
A prospective study was conducted on 100 patients with moderate to severe functional TR and left-sided valvular lesions who comprised two study groups. Group (A) included 50 patients who got tricuspid valve repair utilizing a flexible band constructed of autologous pericardium. Whereas group (B) included 50 patients who had traditional suture annuloplasty. The repaired valve was evaluated intraoperatively.
Postoperative follow-up was done for mean duration of 24 ms±12 ms by clinical examination and transthoracic echocardiography.

Results
Both tricuspid annuloplasty techniques resulted in good short-term outcomes, including improvements in TR status and reduction of right a-trial diameters. The use of a pericardial stripasa flexible band did not exhibit any degeneration or retraction over the duration of the study.

Conclusion
For the surgical repair of functional TR, tricuspid annuloplasty utilizing a pericardial band made of the autologous pericardium is an effective alternative. The surgical decision should be made based on the unique characteristics of the patient and variables related to long-term durability. To verify these findings, more research with bigger populations and longer follow-up times are required.
The rational of Cloquet lymph node as a sentinel lymph node in iliac dissection in lower limb melanoma
Authors: Alhanafy Saad S. , Elsisy Alaa A.E. , Alabassy Mahmoud M. 
Published: December 2023

Background and aims
Intraoperative lymphatic mapping and sentinel lymphadenectomy (LM/SL) is a growingly popular operating procedure for staging regional lymph nodes in early-stage melanoma. The groin is a promising area for this method since superficial groin dissection and iliac dissection have a significant risk of morbidity. There is currently no consensus on how best to treat cases with tumor-positive sentinel lymph nodes (SNs) during surgery involving these basins.

Methods
A total of 182 cases were treated using the LM/SL method. There was consistent detection of sentinel lymph nodes. SN dissection was performed on patients who had tumor in their SN. A hematoxylin and eosin stain was used to analyze the sentinel lymph nodes. Patient selection for SN dissection was based only on the presence of tumor in that node. Computerized database containing log-rank tests and Cox regression models for statistical analysis.

Results
61% of the 182 cases were female, with an average age of 50 (range, 15–89). Tumor-positive SNs were detected in 21% of cases. 67% of cases were identified to have sentinel full lymph node dissection and a single tumor-positive lymph node after LM/SL, whereas 27% had 2 tumor-positive lymph nodes and 6% had 3 or more tumor-positive lymph nodes. Recurrence in the dissected basin occurs in just 4% of individuals with tumor-negative SNs. Cases whose lymph nodes tested negative for tumors had a significantly greater 5-year overall survival (mean±SD, 94% 5%) compared with those whose lymph nodes tested positive for tumors (meanSD, 75% 4%; P 0.01). Primary tumor thickness (P = 0.03), Tumor-positive SN (P 0.001) and ulceration (P = 0.001) were revealed to be important indicators of survival in multivariate studies using a Cox regression model.

Conclusions
This surgical treatment ought to become common for cases with early-stage melanoma of the lower extremities and trunk because the accuracy of LM/SL as judged by the infrequent recurrences implies that it should. When a tumor-positive SN is found in the groin, it is important to take a sample from the Cloquet node so that one may decide whether or not an iliac dissection is necessary.
Endoscopic retrograde cholangiopancreatography plus laparoscopic cholecystectomy versus laparoscopic common bile duct exploration and cholecystectomy for cholecysto-choledocholithiasis − The same operator: a multicenter randomized controlled trial
Authors: Omar Mohammed A. , Redwan Alaa A. 
Published: December 2023

Background
Laparoscopic cholecystectomy (LC) plus either intraoperative endoscopic retrograde cholangiopancreatography (intraERCP) or laparoscopic common bile duct exploration (LCBDE) are one-stage, minimally invasive procedures to treat cholecysto-choledocholithiasis. This study aimed to compare the safety, efficacy, and surgical outcomes of the LC-intraERCP and LC-LCBDE for patients with cholecysto-choledocholithiasis. Both authors completely performed both procedures.

Patients and methods
This multicenter randomized controlled trial included 218 patients with cholecysto-choledocholithiasis randomized to LC-intraERCP (n = 109) and LC-LCBDE (n = 109) treatment groups between February 2019 and October 2022. The primary outcome was a technical success, while conversion to open surgery, operative time, morbidity, mortality, length of hospital stay, and cost were considered secondary outcomes.

Results
Both groups had no significant differences in success (94.5% for LC-intraERCP and 87.2% for LC-LCBDE) and morbidity rate. The conversion to open surgery, the mean operative time, the length of hospital stay, and the cost were significantly lower in the LC-intraERCP. There was no mortality in either group.

Conclusion
LC-intraERCP is safer and more effective than LC-LCBDE for treating cholecysto-choledocholithiasis. Moreover, it is associated with reduced hospital stay and cost.
Effect of coronavirus disease 2019 lockdown on admission of surgical emergencies at Ain Shams University Hospital
Authors: Fadl Ehab M.A. , Helmy Ramy , Hanafy Dina M. 
Published: December 2023

Background:
Globally speaking, the COVID-19 pandemic has had a significant impact on healthcare services. Several publications about the restructuring of surgical activity during the COVID-19 pandemic have been written, but few of them have specifically addressed the effects of this restructuring on the emergency and trauma surgery. The goal of this study was to evaluate the impact of the COVID-19 pandemic and Egypt’s national lockdown on admissions for acute surgical conditions at Ain Shams University Hospitals and compare those numbers to any existing international literature.

Methods:
The data were collected from the records of the surgical emergency department at Ain Shams University Hospital (El-Demerdash) for the period of national lockdown in the months of March, April, May and June 2020 and compared this with the data of the year 2019.

Findings and Results:
Total patients’ visits in the period from first of March till the end of June 2020 was 10294 patients visits with average daily visits 84, while it was 15672 with average daily visits 128 in the same period of 2019. There was a slight increase in the percent of admission from total visits from 30% in the period of March to June 2019 to 32% in the lockdown period in 2020, which means slight decrease of the unnecessary patients visits. The percent of emergency room (ER) operations of total admissions increased in the lockdown period which refer to the decrease in the number of conservatively managed patients of admitted patients.

Conclusion:
The COVID-19 pandemic had its impact on the surgical emergency departments all over the world. It reduced the number of avoidable non-emergency ER visits, but in same time, it hasn’t stopped patients with high-risk surgical emergencies from getting urgent care. Also, during the pandemic surgeons delt with more severe conditions and complications as a result of the pandemic.
Comparative study between 1-year patency of brachiobasilic arteriovenous fistula versus brachial to basilic forearm loop graft in patients with end-stage renal disease
Authors: Mohammed Islam B. , Khattab Mahmoud S. , Wahba Ramez M. , Fakhr Mohammed E. 
Published: December 2023

Background
The most preferred method of vascular access is the autogenous arteriovenous fistula (AVF). When ready for dialysis, autogenous AVF outperforms arteriovenous grafts (AVG) in terms of patency and survival. An alternate method of vascular access for such individuals is the transposed AVF or AVG.

Aim
The goal of this trial is to evaluate and contrast the results of those who were treated with a brachiobasilic (BB) AVF to those who were treated with a polytetrafluoroethylene brachial to basilic forearm loop graft.

Primary endpoints
Assisted primary patency, primary patency also secondary patency. Secondary endpoints: postoperative complications (wound infection, bleeding, steal syndrome, and procedure-related mortality), functional maturity.

Patients and methods
This is a prospective cohort observational trial performed at the Vascular Surgery Department, Faculty of Medicine, Ain Shams University. Data about patients who had forearm loop grafts or BB AVFs during the period from January 2021 to January 2022 were collected according to the study inclusion criteria. There was a total of 50 individuals included (25 patients in each group). The first group included cases who had BB AVF with basilic vein transposition (BB tAVF) whereas the second group included patients who had brachial-basilic forearm loop graft (BB AVG).

Results
Regarding age and sex distribution or risks of cardiovascular events, there was not a statistically significant distinction among the two study groups. The fistula group required statistically significant longer time to achieve functional maturity mean±SD (BB tAVF=9.64±2.29 vs .BB AVG=6.6±2 assisted and secondary patencies at 3, 6, 12, and 18 months). No statistically significant variation existed among groups regarding postoperative bleeding, infection, and procedure-related mortality.

Conclusion
Both BB AVF and polytetrafluoroethylene brachial to basilic forearm loop graft can be considered as viable options for vascular access in this patient population. The choice of procedure may depend on individual patient factors, possible risks of prolonged central venous catheter (CVC) use, as well as the risks of infection and thrombosis, which should be carefully evaluated.
The effect of platelet-rich plasma on sternal healing postmedian sternotomy in patients undergoing open heart surgery
Authors: El-Fiky Mohamed M. , Ahmed Hamdy A. , Fouad Ahmed A. , Elsaka Ahmed B. B. B. , El Ghanam Mohamed 
Published: December 2023

Background
Plasma is the fluid portion of blood which contains clotting factors, other proteins, and ions. Platelet-rich plasma (PRP) is defined as a volume of the plasma fraction of autologous blood with many more platelets than what is typically found in blood. The concentration of platelets and thereby the concentration of growth factors (GFs) can be 5 to 10 times greater (or richer) than usual. The aim of this study is to evaluate the effect of PRP on sternal healing post median sternotomy in patients undergoing cardiac surgery.

Patients and methods
A single-center, prospective, comparative study. We recruited 100 patients who were referred for open heart surgery, through median sternotomy, to our Cardiothoracic Surgery Department, Faculty of Medicine, Ain Shams University, Cairo, Egypt between March 2020 and January 2022. Patients were divided into two equal groups; the study group where we applied topical autologous PRP to the sternal edges before sternal closure, and the control group who did not receive PRP.

Results
The two groups were similar in their demographics. We found no significant benefit in terms of sternal healing between the two groups assessed by measuring bone density. Superficial and deep wound infections were similar in both groups; however, we found a marked reduction in blood loss in patients who received PRP (group 1) compared with control group (group 2).

Conclusion
Applying PRP topically to the sternal edges following median sternotomy did not improve sternal healing of the incidence of superficial or deep sternal wound infection. It may be beneficial in reducing blood loss from the sternal edges and hence blood transfusion requirement following surgery.
