    Bone resorption of the posterior mandible can result in diminished bone edge and, therefore, the installation of implants in these regions becomes a challenge, especially in the presence of the mandibular canal and its contents, the inferior alveolar nerve. Several treatment alternatives are suggested: the use of short implants, guided bone regeneration, appositional bone grafting, distraction osteogenesis, inclined implants tangential to the mandibular canal, and the lateralization of the inferior alveolar nerve. The aim was to elucidate the success rate of implants in the lateralization technique and in inferior alveolar nerve transposition and to determine the most effective sensory test. We conclude that the success rate is linked to the possibility of installing implants with long bicortical anchor which favors primary stability and biomechanics

    For many years, silicone implants were used in reconstructive and esthetic surgeries, especially in cases in which the facial profile of patients presented deficiencies in the inferior third of the face. This material proved to be successful in most aspects. However, several complications were well reported in the literature, as the case of bone reabsorption in the region of the mandibular chin. In this article, the authors present two clinical cases of bone reabsorption from the anterior cortex of the chin associated with silicone implants and discuss the etiology, complications, and treatment plan

    IntroductionThe influence of intestinal microbiota, particularly lactic-acid bacteria, on digestion and nutrient metabolic activities has been extensively studied. In this research, we investigated the effects of supplementing the feed of rainbow trout (O. mykiss) with P. acidilactici or L. lactis probiotics. A Control group without probiotic supplementation was also included. The study aimed to evaluate growth, feed conversion indices, free amino acid levels in serum and feces, and the relative gene expression of amino acid solute carrier transporters (SLC).MethodsRainbow trout weighing 73.9±10 g were fed with a basal commercial diet supplemented with mono-strains of P. acidilactici or L. lactis at a dosage of 5 x 108 CFU per gram of feed for 60 days. The trout were reared in 100-liter tanks with independent closed recirculation systems, with a water replacement rate of 80% of the total volume daily and a controlled temperature of 15 ± 0.3 °C. The proximate composition of the basal diet consisted of crude protein (49.8%), fat (32.1%), fiber (1.31%), ash (13%), and moisture (8.3%) on a dry matter basis. The diet was provided at a rate of 2% of bodyweight per day.ResultsNo significant differences (p > 0.05) were observed in growth and feed conversion indices between the experimental groups. However, significant differences in free amino acid levels in feces and serum samples (p ≤ 0.05) were observed. The P. acidilactici group exhibited significantly higher levels of glutamate, lysine, proline, and tyrosine in feces samples, and higher levels of arginine, iso/leucine, phenylalanine, proline, serine, threonine, and valine in serum samples compared to the Control group. Additionally, the supplemented probiotic groups showed significant downregulation (p ≤ 0.05) of theslc6a19 and slc7a9 genes, which encode transporters for neutral and cationic amino acids.DiscussionThe autochthonous rainbow trout strain, P. acidilactici, demonstrated more pronounced effects on amino acid levels in feces and serum compared to the non-autochthonous L. lactis strain. However, the increased amino acid levels, particularly in the serum, resulting from P. acidilactici supplementation, did not lead to improved trout growth or feed conversion. Nonetheless, lactic-acid bacteria supplementation induced measurable metabolic effects, as evidenced by elevated levels of specific amino acids in the serum and feces.Future research should focus on evaluating these probiotic effects using specialized diets and considering the observed metabolic effects in this study

    Postpartum Depression (PPD) is a clinically complex condition that manifests as a mental disorder. This condition is characterized by profound sadness, feelings of incapacity, and a lack of hope that occur shortly after childbirth. PPD is influenced by a variety of risk factors. These include the mother's past history, socioeconomic and cultural factors, and conditions related to prenatal, childbirth, and postpartum. Past history may include the mother's life experiences, such as trauma or stress, which may increase the likelihood of developing PPD. Socioeconomic factors, such as lack of social or financial support, can also contribute to PPD development. Additionally, conditions related to prenatal, childbirth, and postpartum, such as complications during childbirth or baby health problems, may increase the risk of PPD. To better understand PPD and its risk factors, research was conducted across various databases. This research included articles in Portuguese and English, published from the year 2014 onwards. All selected studies were read in full to ensure a comprehensive understanding of the results. The research highlighted the relevance of various risk factors for PPD. In particular, factors related to the mother were identified as significant contributors to PPD development. These may include the mother's mental health before childbirth, childbirth experience, and available social support for the mother after childbirth. Additionally, the research also highlighted the economic and social impacts of PPD on the healthcare system. PPD can result in significant costs for the healthcare system, including the cost of medical treatment for the mother and the long-term impact on the child's health and development. Furthermore, PPD can have a significant social impact, including the stigma associated with the illness and the impact on the mother's family. In summary, PPD is a complex condition that is influenced by a variety of risk factors. Understanding these factors is essential for the development of effective prevention and treatment strategies. Additionally, it is important to recognize the economic and social impacts of PPD and work to minimize them. This may include providing adequate support for mothers and their families, as well as public education about PPD to reduce the stigma associated with the illness.La Depresión Posparto (DPP) es una condición clínicamente compleja que se manifiesta como un trastorno mental.

    Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation.

    Short dental implants in posterior mandible

    No full text
    The rehabilitation with oral implants is, without any doubt, a consecrated technique. But often we face situations of high bone atrophy where the conventional installation of dental implants is not possible. The posterior mandible, when severely resorbed, generally requires complex techniques to be rehabilitated with implants, such as the lateralization of the inferior alveolar nerve. As an option for these cases, this paper proposes the use of short implants for the rehabilitation of severely resorbed posterior mandible. Copyright © 2013 by Mutaz B. Habal, MD
