Dentistry is an ever-evolving field that has seen significant advances in recent years. This article sheds light on some of the current and emerging trends in oral health care, including digital dentistry, regenerative medicine, and the use of lasers. For example, digital dentistry involves the use of computer-aided design and manufacturing technology, which enables more accurate and efficient production of dental devices. On the other hand, regenerative medicine and nanoDentistry can be considered promising area that combines the use of stem cells, growth factors, biomaterials, and nanotechnology to regenerate damaged tissue and improve treatment outcomes. Lasers are increasingly being used in dentistry for a range of applications, including the treatment of gum disease and teeth whitening. Other developing technologies such as 3D printing and artificial intelligence are also being increasingly incorporated into dentistry, providing improved treatment options for our patients. Last yet definitely would/will not least, controlled drug delivery systems are being developed to deliver drugs to specific target sites in a localized and sustained manner, reducing the risk of adverse effects. Currently, these emerging trends are transforming the landscape of odontology and beyond. Hence, in this mini-Review, we explore such trends in oro-dental and cranio-maxillo-facial indications to highlight the potential benefits, advancements, and opportunities of applications for improved patient care.

Objectives: This study aimed to compare the quality and quantity of bone at intraoral autogenous graft donor sites in type II diabetes mellitus (DM) patients versus healthy controls using cone-beam computed tomography (CBCT). Materials and methods: This case-control study was conducted on CBCT scans of 50 DM patients and 50 healthy controls between 20-70 years. Maximum height, width, length, and volume of harvestable bone at the symphysis, ramus, palate, and tuberosity were measured bilaterally. The Hounsfield unit (HU) was also calculated to assess bone quality. The two groups were compared regarding the quality and quantity of harvestable bone using an independent t-test. The effect of confounders was analyzed by the regression model (alpha = 0.05). Results: DM patients had significantly lower harvestable bone volume at the symphysis, ramus, and tuberosity than healthy controls (p < 0.001) but this difference was not significant at the palate (p = 0.957). Also, bone quality was significantly lower at the symphysis, ramus, palate, and tuberosity in DM patients (p < 0.001). Conclusion: Diabetic patients had significantly lower bone quality and quantity at intraoral graft donor sites than healthy controls. Mandibular symphysis had higher bone volume and density than ramus, palate, and tuberosity for graft harvesting in diabetic patients.

The dynamics of the glucose-insulin regulatory system are highly nonlinear and must be understood to be controlled effectively. Bifurcation analysis and multiobjective nonlinear model predictive control (MNLMPC) are performed on a glucose-insulin dynamic model. MATCONT was used for the bifurcation analysis, and for the MNLMPC calculations, the optimization language PYOMO is used in conjunction with the solvers IPOPT and BARON. The bifurcation analysis revealed a Hopf bifurcation point and a limit point. A Hopf bifurcation point is a tipping point where a system that was behaving steadily suddenly starts to oscillate or cycle on its own, like a machine that begins to vibrate instead of staying still. A limit point is a tipping point at which pushing a system a little further suddenly causes it to jump to a completely different state, rather than changing smoothly. MNLMC converged on the Utopia solution. The Hopf bifurcation point, which leads to an unwanted limit cycle, is eliminated by an activation factor. A limit cycle is a repeating pattern of behavior that a system naturally settles into over time, like a steady heartbeat or a clock that keeps ticking. The limit point (which causes multiple steady-state solutions from a singular point enables the Multiobjective nonlinear model predictive control calculations to converge to the Utopia point (the best possible solution) in the model. A Utopia solution in multi-objective nonlinear model predictive control is an ideal operating point at which all goals are simultaneously perfectly optimized.

Allogeneic hematopoietic stem cell transplant (alloHSCT) is a curative treatment for many hematologic malignancies. Unfortunately, about 30-50% of all recipients undergoing alloHSCT develop acute graft-versus-host-disease (aGVHD), which is associated with high morbidity and mortality [1,2]. Treatment of aGVHD involves the use of immune suppressive drugs such as high dose of steroids that leads to further immunosuppression and risk for opportunistic infections. Often patients are refractory to steroids therapy making the prognosis dismal. Thus, it is critical to identify robust biomarkers to detect aGVHD before onset of clinical symptoms so that therapeutic strategies can be implemented that may result in better treatment responses and less toxicity. 

A 37-year-old woman suffered from a painful and swelling lesion of the base of the tongue, with no history of smoking or medical history of tumours.

Cotton crop is infested with different kinds of insects in the production cycle. Jassids, thrips, aphids and whiteflies are among the sucking pests, and bollworms (American and spotted) and Spodoptera caterpillars attack leaves and bolls. Bollworms can cause up to 40% - 50% crop losses in severe incidences.

Sarcoidosis is a multisystem disease of unknown origin that is characterized by non-caseating epithelioid granuloma formation within various organs, mainly the lungs [1]. The objective of this study is the analysis of sarcoidosis patients affected by pulmonary manifestation alone or extrapulmonary expression.

The National Health Surveillance Agency (ANVISA) is a public institution created by Law 9782/1999, which integrates the field of Collective Health and acts in the prevention, control, and inspection of sanitary conditions in various sectors, such as food, health, pharmacies, hospitals, and commercial establishments. Its main objective is to guarantee the protection of public health, ensuring that products, services, and environments comply with established standards, to promote health and preventing diseases. To exercise its inspection and control function, Sanitary Surveillance has the power of sanitary police, which gives it the authority to apply necessary measures and curb practices that pose risks to the health of the population.The performance of the Sanitary Surveillance is fundamental to prevent health risks in any part of society and to guarantee national programs for patient safety. It is also essential to prevent diseases, control risks, and monitor compliance with health standards and specific regulations. The police power of Sanitary Surveillance consists of establishing norms and technical regulations, carrying out inspections and inspections, issuing temporary or permanent interdiction orders in establishments that do not comply with the norms, as well as forwarding complaints to the Public Ministry in cases of crimes against public health. Arrests carried out by Sanitary Surveillance agents are extreme measures and applied in serious situations of risk to public health or when there is repeated disrespect for sanitary regulations. The prohibited establishments have the right of defense and may seek to regularize the situation to obtain the release of activities.The performance of the Sanitary Surveillance has significant impacts on the prevention of disease outbreaks and epidemics. Identifying and correcting inappropriate practices helps to prevent the spread of pathogenic agents and reduce the risk of contagion in collective environments. The institution’s preventive and supervisory activities contribute to reducing risks to the population’s health, preventing disease outbreaks, food poisoning, and the proliferation of pests, among other problems. Finally, the importance of exercising police power with transparency, impartiality, and respect for individual rights is emphasized, always aiming at the collective interest and the promotion of the common good. In summary, Health Surveillance plays an essential role in protecting public health, seeking to ensure that the population has access to safe products and services, contributing to the improvement of quality of life and disease prevention.

Primary myelofibrosis (PMF) is a distinct clinicopathological myeloproliferatve disease (MPD) not preceded by any other MPD ET, PV, CML,... Combined use of bone marrow histology and increased erythrocyte counts above 5.8x1012/L can replace increased red cell mass at time of presentation as the pathognomonic clue for the correct diagnosis of hetero/homozygous or homozygous mutated PV. Erythrocyte counts are in the normal range below 5.8x1012/L in heterozygous JAK2V617F mutated ET and prodromal PV but above 5.8x1012/L in heterozygous-homozygous or homozygous mutated PV. The bone marrow cellularity and morphology in pre-fibrotic ET, prodromal PV and PV carrying the JAK2V617F mutation are overlapping showing clustered increase of large mature pleomorphic megakaryocytes (M) with no increase of cellularity (<60%) in ET. The bone marrow is hypercellular (60%-80%) due to increased erythropoiesis megakaryopoiesis (EM) in prodromal and classical PV and trilinear hypercellular (80%-100% due increased megakaryopoiesis, erythropoiesis and granulopoiesis (EMG) in advanced PV and masked PV. Bone marrow cellularity ranging from normal (<60%) in ET to increased erythropoiesis (EM) in prodromal PV to hypercellular (80-100%) in advanced PV and masked PV largely depends on increasing JAK2V617F mutation load from low to high on top of other biological MPN variables like constitutional symptoms during long-term follow-up. MPL515 mutated ET is featured by an increase of clustered small and giant megakaryocytes with hyper-lobulated staghorn-like nuclei in a normal cellular bone marrow. The third entity of pronounced JAK2/MPL wild type ET associated with primary megakaryocytic granulocytic myeloproliferation (PMGM) without PV features proved to be caused by calreticulin (CALR) mutation. CALR mutated thrombocythemia is characterized by dual proliferation of megakaryocytic and granulocytic bone marrow proliferation of dense clustered large to giant immature dysmorphic megakaryocytes with bulky (bulbous) hyperchromatic nuclei, which are not seen in MPL515-mutated Thrombocythemia and JAK2V617F-Thrombocythemia, prodromal PV and classical PV. 

The spleen plays a pivotal role in our immune system by facilitating the proliferation and differentiation of lymphocytes and monocytes. Typically located in the left upper quadrant retroperitoneally, splenic tissue found outside of its usual position is termed ectopic spleen. When the tissue maintains its histological architecture and encapsulation and receives blood supply from splanchnic vessels, it is called an accessory spleen. Although it commonly presents near the splenic hilum or pancreatic tail, rare instances have been reported in the gastric, liver, gastrosplenic/lienorenal ligaments, as well as thoracic and gonadal regions. However, the case of an accessory spleen, mimicking a hepatic lesion in the right diaphragm represents a novel observation.
