Authors: Jaume Alejandra , Salle Federico , Pereda Pablo , Martínez Fernando , Sgarbi Nicolas , Russo Alejandro
Published: October 2018

The study of the mesial aspect has gained importance due to its anatomic complexity and its relationship to the surgical treatment of epilepsy. The aim of this paper is to do an anatomo-radiologic correlation of the morphology and topography of the mesial aspect of the temporal lobe, with its neurosurgical application in the treatment of diseases in the region. Eight (8) adult formalin fixed hemispheres with no pathologic signs were studied. On 4 of them sections within the 3 planes were performed (sagittal, coronal and axial), for radiologic correlation. On the remaining 4, dissection of the mesial region was done, in order to correlate the structures found during surgical approach to the region. Both in the cadaveric hemispheres and in the radiologic images, structures from the mesial region were identified, this included: collateral sulcus, rinal sulcus, parahippocampal gyrus, temporal uncus, hippocampal sulcus, hippocampus with its 3 sectors (head, body and tail), the inferior choroidal point and the collicular point that divides the hippocampus intro 3 sectors (anterior, medium and posterior). With the results obtained, the principal anamoto- radiologic aspects of the approach to the mesial aspect of the temporal lobe were analyzed, comparing them with results of previous reports. The proper knowledge of both morphologic and topographic anatomy of the mesial aspect of the temporal lobe is crucial for both interpreting radiologic studies and a correct surgical approach for surgical treatment of epilepsy.
Scientific Production and h-Index of Chilean Specialists in Digestive Surgery
Authors: Cantín Mario
Published: October 2018

The Hirsch index (h-index) is recognized as an effective way to summarize, an individual’s scientific research output. However, a benchmark for evaluating surgeon scientists in the field of digestive surgery is still not available. The bibliometric evaluation was conducted on the Scopus Database on all active members joining the Chilean Surgical Society, specifically, digestive surgery specialists. Scientific production was analyzed by considering the number of total publications, number of total citations and h-index; the geographical data for each case was also recorded. The median h-index for the digestive surgeons was 2 (4.3±6.8; range, 0-40); 76.8% of digestive surgeons had at least one scientific journal indexed in Scopus. The 43 surgeons analyzed, jointly published a total of 1011 articles (minimum 1, maximum 434), which were cited 9424 times (range 0 to 5368 citations), with a Median of 30 citations. Additional, 62.5% of digestive surgeons are from the city of Santiago. Of the authors with a higher h-index 3, only two were not from Santiago. The difference in h-index between men and women was statistically significant. Bibliometric analysis of the scientific production in digestive surgery may facilitate the recognition of factors that may further enhance research activity and clinical performance, and be useful for a comparative assessment of authors or research groups in terms of quality and quantity of the scientific production.

Trigeminal Neuralgy
Authors: Vásquez Bélgica
Published: October 2018

The objective of this review was to present information on the main causes, possible treatments and morpho-quantitative aspects of trigeminal neuralgia. Trigeminal neuralgia is a condition characterized by intense facial pain, severe throbbing or stabbing; it is usually unilateral and recurrent and is located in the facial area innervated by the trigeminal nerve. The causes of this disease are varied and include neurovascular compression stresses. Medical treatment of choice is carbamazepine, reserving surgical treatment for cases resistant to medical therapy or cases when side effects of drugs used, outweigh the risks and disadvantages of surgery. In this context a detailed knowledge of the structure of the trigeminal nerve and its morphoquantitative characteristics could provide relevant information to make type of treatment more effective.

Authors: Arellano María , Alveal Diego
Published: October 2018

During the last years there has been an important increase in the research of associations between periodontal disease and some systemic diseases, looking for a relationship beyond the single epidemiological coincidence. Rheumatoid arthritis (RA) is a chronic systemic disease that damages the bone and connective tissue; despite a low prevalence in the population, the disease has a high morbidity in patients. Rheumatoid Arthritis and Periodontal Disease have common pathophysiological characteristics. A negative influence of periodontal disease over rheumatoid arthritis has been suggested, this has led to increase the interest of studying and elucidating the relationship and possible effects of periodontal therapy on the metabolic control and severity of RA.

Published: October 2018

Zygomatic-orbital complex fractures are common in the middle face. As a protocol, it is necessary to establish an adequate exposure of the surgical site. The best surgical approach still remains a lot of controversy. However, the bicoronal flap is a versatile surgical technique to expose the craniofacial skeleton and allow an appropriate access to reduce and fix the fractured segments, being therefore a good alternative for the treatment. The association of other surgical approaches could promote better exposure of the fractured areas, turning an invasive procedure more complete and favorable. This article aims to report a case of zygomatic-orbital complex fractures and suggest a coronal approach along with others techniques to treat this kind of trauma. The great outcomes showed a satisfactory rehabilitation, fractures stabilized, favorable function and good aesthetic.
Epidemiology and Clinical Epidemiology
Authors: Manterola Carlos
Published: October 2018

Epidemiology is a medical discipline in which the subject of study is a group of individuals who share some common feature. It is very useful to measure and quantify the level of health in populations; describe diseases; identify determinants of disease; act on the control and prevention of these; and to take action planning and evaluation health. Meanwhile, clinical epidemiology is the application of epidemiological principles and methods to problems in clinical practice; and its purpose is to promote methods of observation and interpretation that lead to valid conclusions. For the socalled father of clinical epidemiology, this is a "Science of art of medicine". Science, because it is based on knowledge, logic and previous experience that has no explanation. And art, because it is based on beliefs, judgments and intuitions without explanation. The aim of this manuscript is to summarize the differences between epidemiology and clinical epidemiology; as well as the following concepts: epidemiological object, method and epidemiological strategy.

Published: October 2018

In implantology, an increase in the bone thickness of the alveolar ridge is often associated with the use of autogenous bone, which is considered to be the gold standard. The aim of the present study was to report the clinical case of a patient with abnormal bone thickness in the alveolar ridge, causing severe esthetical damage, and the use of xenogeneic block bone grafts. A female, 43-year old patient exhibited a considerable bone defect in the region of teeth 11 (absent), although there was sufficient native bone available for the implantation. The patients treatment involved positioning the implant and performing a block bone graft using bone of bovine origin. The post-operative period passed without complications. The post-operative clinical examination confirmed the correction of the pre-existing esthetic defect and the health of the soft tissues involved. The tomographic examination 180 days post-surgery also confirmed an excellent increase in thickness. The bovine block bone graft used in the present case was shown to be viable in terms of correcting esthetic defects when there is sufficient native bone available for the implantation.

Authors: Manterola Carlos
Published: October 2018

Ganglioneuroma (GN) is a benign infrequent tumor whose most common site is the abdomen. Theyare usually asymptomatic and usually diagnosed incidentally by imaging study. Treatment is surgical and indication for surgery depends on the size and location of the lesion; as well as the symptoms that are possibly generated. Even though there is evidence of laparoscopic resection in some cases of retroperitoneal location based on isolated cases reporting promising results, the main access road remains the traditional way. The aim of this article is to provide a case of thoracoabdominal retroperitoneal GN and discuss the related literature.

Pancreatic Insulinoma. About a Personal Experience of 3 Cases
Authors: Manterola Carlos
Published: October 2018

Pancreatic insulinomas (IP), are uncommon tumors that come from the beta cells of pancreatic islets, which are characterized by producing insulin excessively, therefore causing hypoglycemia; which is manifested by neuroglycopenic and autonomic symptoms. IP diagnosis is proposed by Whipple's triad, characterized by hypoglycemia, neuroglycopenic symptoms and the reversal of the symptoms following the administration of glucose. Surgery remains the treatment of choice for IP, either by laparotomy or laparoscopy, performing enucleation or segmental pancreatectomies. These procedures are not free of complications, most notably are pancreatic fistula, and pseudocyst formation, and the development of diabetes mellitus. The aim of this paper is to report the personal experience in treating consecutive patients with PI and discuss the related literature.

Published: October 2018

The Human Anatomy is an ancient Science, which uses the human body as the main material of study. However, structural differences between individuals that make up the species are quite common in the population and always emerge as a source of reports that aim to demonstrate and clarify these differences. These structural changes are called anatomical variations and may be presented externally or internally in any of the body systems, with no functional impairment to the individual. The salivary glands are exocrine glands that secrete saliva directly into the mouth through their ducts. This secretion has the functions of keeping mucous membranes moist, cleaning teeth, lubricating, dissolving and starting the food digestion process. Most of the saliva is secreted by the major salivary glands, the parotid glands and the submandibular glands, the latter being the focus of this case report. The purpose of this paper is to report a case of finding an accessory submandibular gland on a cadaver from the Human Anatomy Laboratory of the University Center of Rio Grande do Norte located in Natal, Rio Grande do Norte, Brazil. The discovery was made during a dissection of an adult male body in 2012, where an accessory submandibular gland was found in the right antimere. Thus, by identifying such variations, its clinical importance can be observed for the purpose of diagnostic imaging, surgery and anatomical teaching applied to clinic, given the scarcity of published reports, thus providing better understanding those working directly or indirectly on the subject.

Spermatogenesis is a complex physiological process that involves cell proliferation, meiotic division and a final cell differentiation of post-meiotic cells into spermatozoa. During this process male germ cells also undergo a metabolic differentiation process, in which post-meiotic spermatogenic cells (spermatids) but not meiotic spermatogenic cells (spermatocytes) respond differentially to D-glucose metabolism, glucose transporters (GLUTs) distribution and utilization of non-hexose substrates, such as lactate/pyruvate or dihydroxyacetone. These differences might be explained by the requirement for a specific metabolic process to support cell differentiation or in some cases, cell viability. In addition, though glycogen is considered to be the main glucose store, in male germ cells this polymer may play a novel role in cell proliferation, acting as a new marker for apoptotic events in testicular tissue via a yet unknown mechanism. In this article, we summarize the main metabolic changes that occur during male germ differentiation, with a specific focus on metabolic sources during spermatocyte to spermatid transition. The latter considering that these cells come from the same cell linage as specialized cells, but are not isolated from their environment, describing the roles from single molecules to polymers on the viability of male germ cells.
ADAM17 As Inducer of Male Germ Cell Apoptosis
Authors: Moreno Ricardo
Published: October 2018

Apoptosis during mammalian spermatogenesis is important to control sperm output and to eliminate damaged unwanted cells. A deregulation in apoptosis rate has deleterious consequences and leads to low sperm production. Apoptosis in spermatogenesis has been widely studied, but the mechanism by which it is induced under physiological or pathological conditions has not been clarified. We have recently identified the metalloprotease ADAM17 (TACE) as a putative physiological inducer of germ cell apoptosis. ADAM17 is widely distributed enzyme in many tissues, its main function is to shed (release) its substrates, which leads to the activation of different signaling pathways according to the cellular context. However, in spermatogenesis, ADAM17 is involved in the control or induction of germ cell apoptosis, this seems to be unique and may reflect the complexity of spermatogenesis. In this review I will focus on the published evidence that show how this enzyme involved in the control of germ cell apoptosis during physiological condition and in different insults such as heat stress, DNA damaging agent or endocrine disruptors.
Sperm Conjugates (Association of Several Sperm in the Epididymis) Reach Zone Fertilization in Rats, but Fertilizes Only One Sperm

En mamíferos se produce el fenómeno de conjugación espermática, tanto dentro del epidídimo como post eyaculación. Los conjugados espermáticos consisten en decenas hasta cientos de espermatozoides asociados. La conjugación de espermatozoides se ha encontrado en el eyaculado de algu- nas especies pero se desconoce si ascienden por el tracto femenino alcanzando la zona de fertilización (tercio distal de las trompas) y si la disociación es previa o durante la interacción con el cumulus ovocitario. Se han propuesto distintos mecanismos por los cuales la formación de estas estructuras favorecerían la fecunda- ción: a. incremento en la velocidad de desplazamiento por sinergia respecto de espermatozoides individua- les, particularmente en casos de competencia espermática, b. protección de los espermatozoides conjuga- dos frente al medio hostil, c. prevención de una reacción acrosomal anticipada, entre otros. Nuestro grupo describió este fenómeno en rata y ratón denominándolos Rosetas y propusimos un posible mecanismo asociativo. Estos conjugados consisten en grupos de espermatozoides unidos por sus cabezas y con sus flagelos libres en un número no menor a 10 células. Se describieron dentro del lumen de la región de la cola del epidídimo, pero no en localizaciones más proximales, sugiriendo que para asociarse entre sí los espermatozoides deben haber madurado y tomado contacto con factores del fluido epididimario. Para cono- cer cuál es el destino final de los conjugados espermáticos se estudió la presencia de gametas masculinas conjugadas o no en el tracto genital femenino de rata luego de la eyaculación. Muestras del contenido de las trompas obtenidas a diferentes tiempos post apareamiento nos permitieron observar conjugados cerca de los complejos cumulus - ovocito. Pero sólo se observaron espermatozoides individuales entre las células del cumulus. Esto sugiere que los conjugados de espermatozoides luego de alcanzar la zona de fertilización se separan en espermatozoides individuales.
Foreign Gene Expression in the Mouse Cauda Epididymis is Regulated by Androgens
Authors: Esponda Pedro
Published: October 2018

This paper deals with the efficiency of in vivo gene transfer to the mouse cauda epididymis and its relation to androgens. Previous experiments in the female reproductive tract have indicated that the efficiency of transfection is related to the hormonal stage of the animal, nevertheless no analysis have been done in the male tract. We used in vivo gene transfer to the mouse cauda epididymis employing a gene construction that expresses the Green Fluorescent Protein (GFP). Untreated and Testosterone treated males were employed. Testosterone injections (5 μg/g weight) were done from 2 days before the gene transfer, and treatment continued each day during a total period of 15 days. Fluorescence microscopy observations showed the expression of GFP in the cytoplasm of the principal cells in the epididymal tubules. The application of the QWin Program that measures the percentage of fluorescent areas showed that they are increased in the epididymis of treated males. This increase was particularly observed two days after gene injections (from 32.24 % in untreated animals to 47.62 % in testosterone treated males) and after seven days (from 29.98 % to 43.05 %). The possibility to improve transfection efficiency would increase the knowledge on epididymal physiology and would permit to modify the fertilizing capacity in mammals.

Authors: Espinoza-Navarro O. , Bustos-Obregón E.
Published: October 2018

Organophosphate pesticides are widely used to eliminate pests in agriculture. In Arica- Chile, they were used to control and eliminate the plague of fruit fly (Ceratitis capitata). They act as acetylcholinesterase inhibitors and induce DNA damage. The aim of this study was to analyze the effects of malathion and methamidophos two organophosphate pesticides on male reproductive parameters of red earthworm Eisenia foetida. After determining the LD50 in mg per kilogram of soil (malathion= 880 mg/kg and methamidophos= 85.3 mg/kg), we proceeded to subdue Eisenia foetida at a dose of 1/10, 1/6, 1/3 and 2/3 of the LD50. The control groups were sprayed with water. All groups were analyzed at 1, 6, 15 and 30 days post treatment. The weight and external morphological changes was determined. Sperm count was held in camera Neubaur, DNA integrity was determined with Acridine orange test. The Ethics / Bioethics Committee at the University of Tarapaca, approved the research protocols. The results show that both organophosphate express a significant decrease in body weight in all animals treated with 100% of coiled tail. A significant rise in the number of sperm at 1, 6 and 15 days followed by a significant decrease from 15 to 30 days was observed. A significant increase of abnormal metachromatic sperm (red fluorescence) in all treated animals was observed. It is concluded that malathion and methamidophos, alter the external morphology, sperm count and quality of Eisenia foetida red earthworm. The use of these chemicals needs better handling and storage procedures to avoid altering human health and the environment.
Cytoreductive Surgery and Hyperthermic Chemotherapy Role in Peritoneal Carcinomatosis Treatment
Authors: Manterola Carlos
Published: October 2018

The aim of this article is to provide a review of some current therapeutic strategies for patients with peritoneal carcinomatosis (PC), which historically has been considered a terminal condition, only amenable to palliative care, and occasionally systemic chemotherapy alone with poor response and lower average survival. The combination of cytoreductive surgery (CRS), which involves peritonectomy and multivisceral resections and intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) is a relatively new intraperitoneal treatment of microscopic residual disease concept. The indication of this method has been extended progressively to highly selected patients with PC and it is based in several phase III studies, which concluded that it is possible to obtain sufficient cytoreduction. However, until now there is some consensus based on evidence, in which HIPEC would be indicated in patients with peritoneal PC originated in pseudomyxoma, peritoneal mesothelioma and colorectal cancer; and CP from another source, depending on each particularcase.

Authors: Letelier Claudia , León Matilde , Boesing Lucinéia , Ortega Rodolfo , Pantoja Roberto
Published: October 2018

Infant facial fracture incidence is low. Most reported cases affect the jaw and are single fractures. We present a twenty-two-month old patient, who had a high-energy car accident. Among other injures, she suffered a multiple mandibular fracture: bicondylar, left body and right parasymphyseal. Stable internal fixation of parasymphyseal and body mandibular fracture was performed on the third day. Condylar fractures had a functional treatment with switching elastic traction to prevent ankylosis. Computed tomography (CT) showed mandibular condyles remodelling after six months. Clinical examination showed that mandibular movement ranges were preserved without alteration. Successful treatment of paediatric patients is based on the achievement of an adequate anatomic reduction and the stability of the fracture, allowing opportune form and function recovery, in order to assure further development of dental and facial structures.

Coronectomy in Third Mandibular Molars as an Alternative Treatment to Prevent Damage to the Inferior Alveolar Nerve: Bibliographic Review and 30 Cases Report
Authors: Guerrero Fermín , Huitzil Enrique , Luna Abraham , Flores Beatriz
Published: October 2018

The inferior alveolar nerve (IAN) injury to remove the third molars is often caused by the intimate relationship between the nerve and the roots of the teeth. Coronectomy technique or intentional root retention, may minimize this problem. Thirty patients underwent coronectomy in 30 third molars with follow up of at least 6 months. Coronectomy technique deliberately protected the lingual nerve as part of the surgical procedure. All roots were at least 3 mm below the buccal and lingual bony walls. All patients were radiographed preoperatively, immediately postoperatively, and after 6 months. There were no cases of IAN damage involved in this study of 30 patients who underwent 30 coronectomies. There was one case of transient lingual nerve involvement, probably by the use of lingual retractor. One patient required subsequent removal of the roots of both lower third molars, due to lack of healing, and one patient required subsequent removal of a root cause of migration back to the surface. migration of the roots was observed in approximately 30 % of patients during a period of six months. Coronectomy seems to be a viable technique in those cases where the removal of all tooth could put the IAN at considerable risk of damage. The technique appears to be associated with a low incidence of complications, but the subsequent migration of the roots can be a problem in the long term.

She was treated with immunoglobulin every two weeks for six doses after two months of hospitalization with achieved improvement. Currently, episodes of seizures have decreased significantly and almost not convulsing, she presented alterations in neurodevelopment.
Effects of Smoking on the Microbiota and Periodontal Tissue: Literature Review
Authors: Cid Felipe , Soto Bárbara
Published: October 2018

Periodontitis is a chronic local inflammatory disease of tissue supporting the teeth that leads to progressive loss of periodontal ligament and alveolar bone. Smoking is a known risk factor for many diseases and increasing evidence suggests that smoking negatively affects periodontal health. Cigarette smoking increased periodontal pathogenic bacterial flora, increasing their pathogenicity and alterations in the periodontal tissue, however the effect of smoking is not directly to these bacteria. Nicotine causes a decreased blood flow and decreased capillary hindering the immune response against pathogenic bacteria. In addition, the immune system is suppressed, so the action of leukocytes is poorly effective against periodontal disease. In conclusion, smoking, mainly nicotine, affects the gingival blood flow, cytokine production, the neutrophil function, replacement of connective tissue and because of these factors, increases the number of periodontal pathogenic bacteria which negatively affects the periodontal tissue.

Vinasse and biocarbon are used as recuperators of saline-sodium soils. The objective was to analyze remediation process of saline-sodium soils in the district of Tambo Grande, Piura. A sample of 10 kg of saline soil was used and it was taken to the laboratory for testing. Two columns of ground were built; at the lower end of each column was placed a leachate collecting vessel. The columns were divided into two treatments: the first was treated with water and the second was treated with vinasse; the conditions of the field washing were simulated for each column, periodically the leachates were analyzed and at the end of one month of treatment was performed analysis each of the soils in the columns. The final results indicated a decrease PSI (0.49), sodium (3.52 meq/L), Electrical Conductivity (1.46 dS/m), as well as an increase of nutrients mainly potassium (20 meq/L) and percentage of organic matter (2.17%). To evaluate the effectiveness of the soil, tests were carried out in pots with a culture called wild radish (raphanus sativus) in four pots of which one was a blank sample (without any treatment) and the remaining three had the soil treated with vinasse with different proportions of (25%, 50%, 75% by weight), for which the growth (cm) and vigor (number of leaves, number of shoots) of the crop were taken as parameters. The results indicated a better growth in the treatment with 25% of biochar, also evidenced the lack of growth in the control treatment.
Reduction of Coliforms presents in domestic residual waters by Air-Ozone Micro-Nanobubbles In Carhuaz city, Peru
Authors: Cruz Rudy , Valverde Flores Jhonny
Published: October 2018

Peru generates approximately 2 217 946 m3 per day of wastewater discharged to the sewage system and only 32% receive treatment. The rest of the waters are discharged to the rivers, which have presence of fecal coliforms. Preliminary analyzes of the domestic wastewater of the Carhuaz district were carried out, with total coliforms (at 35ºC) of 240,000 CFU / 100 mL and thermotolerant coliforms (at 44.5ºC) of 130,000 CFU / 100mL at pH 7 , 17 exceeding the environmental standard values. The treatments were carried out with the air-ozone micro-nanobubbles generator with a water flow rate of 4.67 L/min and a pressure of the air-ozone mixture of 90 PSI, achieving a reduction of total coliforms up to 100 CFU/100 mL (99.96%) and fecal coliforms up to 100 CFU/100mL (99.92%)
Efficiency Of Micro-Nanobubbles for Wastewater Treatment in Puerto Bermúdez, Oxapampa, Pasco

Published: October 2018

In our country, the wastewater discharges affect to water bodies, public health and as well as different ecosystems without any kind of treatment. For this reason, a different and effective treatment is proposed for the minimization of total coliforms present in the wastewater from Puerto Bermudez, Oxapampa, Peru with the generation of air micro-nanobubbles. The degree of contamination shown in the different physico-chemical and biological parameters was determined; as well as their impact’s minimization to obtain a better quality of life.The research was experimental, the assembly of the air micro-nanobubbles generator was done to get treatment by dosage. The analysis were carried out to determine the degree of contamination and thus treat them with air micro-nanobubbles in different quantities and thus have the best result. The results of the treatment with air micro-nanobubbles were favorable.  The efficiency achieved was 66.21%.

New effects in and control of exciton systems in quasi-two-dimensional structures
Authors: Lozovik Yu E
Published: October 2018

New effects in systems of quantum dipoles are discussed, such as anisotropic superfluidity in external fields, strong correlations, crystallization, and the supersolid phase. Roton instability effects typical of strongly correlated Bose systems but also manifesting themselves in weakly interacting systems of titled dipoles are analyzed. Among the interesting physical realizations of the systems under consideration are dipole excitons in single or coupled quantum wells under a strong transverse electric field and in van der Waals heterostructures of new 2D materials, such as transition metal dichalcogenides (TMDCs). The use at ultralow temperatures of polar molecules or atoms with permanent or external-field-induced dipoles is also interesting, as are Rydberg atoms in an external electric field.
L’Hôtel-Dieu de Tonnerre. Questions d’architecture
Authors: Boulet Jacques
Published: October 2018

Il ressort des divers récits sur l’Hôtel-Dieu de Tonnerre une histoire architecturale de l’édifice Hôtel-Dieu centrée sur les dimensions exceptionnelles d’une nef unique sur le plan basilical, à la fois église et salle des malades. La généalogie d’une singularité architecturale est réduite aux dimensions imposantes de l’Hôtel-Dieu, dont le classement au titre de « monument historique », en 1842, autorise la démolition de ce qu’il reste de l’histoire architecturale et urbaine de la Maison-Dieu initiée en 1292 et vouée aux Sept Miséricordes par Marguerite de Bourgogne.Le vestige de la Maison-Dieu participe alors d’une histoire de la monumentalité, où les valeurs mémorielles du document d’architecture qui justifient son devenir monument entrent en tension, sinon en conflit, avec ses valeurs d’usage au sens large.L’ouverture de la nef à des manifestations diverses illustre la pérennité de l’usage cultuel qui demeure (messe d’anniversaire de la mort de Marguerite de Bourgogne), et le passage très lent de l’usage hospitalier, abandonné en 1642, à un usage culturel.Au-delà de la seule vertu d’un grand contenant culturel, l’hospitalité offerte à des installations artistiques éphémères instaure un rapport nouveau à l’architecture de l’édifice, un sens nouveau du monument, de nouvelles perceptions de sa monumentalité. Ce qui fait œuvre avec les installations de Caroline Coppey et de Didier Guth, ce n’est pas tant le placement in situ des installations que la « prise de site » qu’elles opèrent et l’expérience esthétique qu’elles proposent. L’ici de l’installation ouvre sur un ailleurs, un espace de déplacements libres avec ses réversibilités et ses temporalités, un autrement de l’espace muséal et monumental.
