Treatment of maxillary transverse deficiency with rapid expansion of the palate with mini-implant: a review

One of the most prevalent malocclusions is maxillary constriction, which is a narrowing of the upper arch; its etiology is multifactorial, including mainly genetic factors and parafunctional habits. It is characterized by a posterior crossbite that can be unilateral or bilateral, total or partial, and may even not occur in cases with simultaneous constriction of the mandibular arch. Transverse deficiency or maxillary hypoplasia affects facial growth and the integrity of the dentoalveolar structures. Therefore, it must be corrected as soon as it is diagnosed. As the maxilla widens, the midpalatal suture and the intermaxillary suture expand. When they are not fused, it is connective tissue and behaves viscoelastically in response to externally applied forces. In order to effectively treat any dentofacial deformation, an early diagnostic and therapeutic approach is required

Intentional replantation: case report

Intentional reimplantation is a procedure in which an intentional tooth extraction is performed followed by reinsertion of the extracted tooth. We present the case of a 50-year-old male patient who came to the consultation due to incrustation detachment in tooth #37, when performing the radiographic study an extensive apical lesion was observed in tooth #36 with a sinuous path and the presence of purulent exudate. The tooth #36 was extracted, apicoectomy, retro preparation and retrograde filling were carried out for later reimplantation, showing bone regeneration after one year of evolution

Endodontic regenerative treatment for internal radicular resorption using bio-ceramic material, case report

The internal resorption of the internal radicular conduct is a process than can be both physiological or pathological, being the osteoclasts, odontoclasts and dentinoclast responsible for said process. 49-year-old female patient, refers orthodontic treatment at age 20, attends a dental check-up due to pain when chewing. Dental organ (DO) #11 was diagnosed with internal root resorption and symptomatic, suppurative apical periodontitis. Treatment started performing an endodontic access and taking a conductometry reading with an apical foramen locator, using a precision hybrid instrumentation technique and applying hypochlorite irrigation, the intra-canal was medicated with chemically pure calcium hydroxide for 7 days. The canal obturation was repaired infiltrating a bio-ceramic material (BIO-C Sealer) followed by the placement of the single cone using a vertical condensation technique

Acute stomal necrosis, conservative management. Case report and literature review

It is estimated that in the world in 2019 there were 1.3 million people living with an ostomy, and that each year in the US around 100,000 colostomies are made, most of which are performed due to trauma or cancer, offering a fairly good alternative In acute cases but they are not exempt from complications , one of the less frequent is ostomal necrosis which is generally managed surgically , we present the case of a patient who due to advanced cervical cancer had to undergo an urgent loop colostomy due to intestinal obstruction , which on the second day presented a purplish coloration and was managed conservatively and resolved spontaneously . We present this case as an alternative treatment for this ostomy complication for the knowledge of the scientific community

Transformaciones y retos de la educación en las artes y los diseños (tomo 1)

El presente libro contiene doce reflexiones que nos sugieren un balance para repensar la educación superior tras las experiencias pandémicas en tres dimensiones: pedagogía, didáctica general y didácticas especiales, Estas tres dimensiones ofrecen un panorama integral para repensar los problemas educativos actuales. A diferencia de otros balances que hemos visto o leído en los últimos años, el presente se compone de tres ejes que atraviesan todas las reflexiones: reorganización de ideas, consolidación de la inter y transdisciplina, y mejora efectiva de las prácticas de enseñanza-aprendizaje desde planes y programas de estudios hasta actividades entre docentes y alumnos.Coordinadoras: Alma Elisa Delgado Coellar, Juana Cecilia Angeles Cañedo & Daniela Velázquez Ruí

The Caldera. No. 24

El poder extraordinario que tiene la literatura, en la vida de un ser humano, es incalculable; no sólo es abrir un libro y pasar los ojos por las páginas; ¡No! Es dejarse atrapar, dejarse llevar por mundos y contextos distintos, diversos, pletóricos de vivencias humanas que nos hacen únicos e irrepetibles. Cada vez que abrimos un libro y nos damos el permiso de leerlo, nos volvemos mejores seres humanos, porque comprendemos más al otro, o por lo menos, tratamos de reconocer cómo vivían, cómo pensaban, cómo actuaban, en otras épocas, incluyendo la nuestra. Con la lectura, podemos entender por qué los seres humanos son como son, potenciamos la empatía y fortalecemos la conciencia moral, entre algunas ventajas que tiene este proceso que nos acompaña a lo largo de toda la vida. Este año, en la mejor Feria del Libro del Oriente Colombiano, ULIBRO 2021, que se realiza del 30 de agosto, al 4 de septiembre, estamos invitados a participar en conversatorios, talleres, encuentros con autores, entre otras actividades propuestas, de manera presencial y virtual, para seguir fortaleciendo nuestro proyecto de vida; también, estamos invitados a dejarnos contagiar de la lectura, de la escritura, de la oralidad, a partir de “Las historias asombrosas”, que se van a tomar los diferentes espacios propuestos.1.

It is to let yourself be trapped, to let yourself be carried away by different, diverse worlds and contexts, full of human experiences that make us unique and unrepeatable. Every time we open a book and give ourselves permission to read it, we become better human beings, because we understand others more, or at least, we try to recognize how they lived, how they thought, how they acted, in other times, including ours. . With reading, we can understand why human beings are the way they are, we enhance empathy and strengthen moral conscience, among some advantages that this process has that accompanies us throughout our lives. This year, in the best Book Fair of the Colombian East, ULIBRO 2021, which takes place from August 30 to September 4, we are invited to participate in talks, workshops, meetings with authors, among other proposed activities, in person and virtual, to continue strengthening our life project; Also, we are invited to let ourselves be infected with reading, writing, orality, starting from "The amazing stories", which are going to take the different spaces proposed

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Long-term thermal sensitivity of Earth’s tropical forests

The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (−9.1 megagrams of carbon per hectare per degree Celsius), primarily by reducing woody productivity, and has a greater impact per °C in the hottest forests (>32.2°C). Our results nevertheless reveal greater thermal resilience than observations of short-term variation imply. To realize the long-term climate adaptation potential of tropical forests requires both protecting them and stabilizing Earth’s climate
