    Perinatal mortality is a relevant indicator of a country health status. Through the centuries, measures have been promoted to reduce modifiable risk factors or to treat installed diseases. That was the example of the English medical doctor John Clarke (1758/1760?-1851), who dedicated his life to mother-child health care [1]. Among his contributions is the report of a placental tumour in 1798, named Chorangioma placenta (CP) [2]. It may occur in primiparas or multiparas, apparently increasing with the mother’s age, with association to the mother’s hypertension or diabetes mellitus [3]. Chorangioma may appear in single or multiple pregnancies and may lead to foetal heart failure, hydrops, or sudden intra-uterine death [3]. The authors report the case of a 2 cm diameter chorangioma (Fig. 1A), which ended in premature death of the male foetus in utero at 35 weeks and 5 days, in a multiparous mother. Histopathological examination confirmed the macroscopic suspicion by disclosing a benign vascular capillary proliferation (Fig. 1B) positive for endothelial markers CD34/CD31 (Fig. 1C). Its current incidence ranges from 0.5% to 1% of analysed placentas [4] and may represent a primitive angioblastic tissue malformation, aggravated with hypoxia and/or haemodynamic changes during pregnancy. To conclude, we highlight the relevance of chorangioma as a cause of perinatal death, which is around 30% [4]info:eu-repo/semantics/publishedVersio

    Dental abscess and “unexpected death”...

    Even though we are living in an era of major technical-scientific advances and effective antimicrobial and antiviral therapy,dental infections are still the most important predisposing factors for head and neck infections. Odontogenic infections can cause severe complications, e.g. compromised airways, tissue necrosis, deep neck infections, mediastinitis, endocarditis and sepsis. These severe odontogenic infections can be potentially life-threatening. Usually odontogenic infections respond well to a combination of surgical treatment (incision, rainage) and antibiotic therapy. However, especially when the medico-surgical therapy is installed late, cases may evolve unfavourably and be fatal. The authors report a case of a 30-year-old man who was observed on three consecutive occasions by the General Practitioner in a District Hospital, for a decayed tooth with abscess and was, then, referred to a Central Hospital. There, he was examined for the fourth time, this one by a Stomatologist at the Emergency Department, where he died. The post mortem examination revealed bacterial (Gram +) acute neutrophilic (purulent) infection of soft tissues of the mandibular region and neck with para-tracheal extension, as well as thrombosis ofthe left jugular vein. Circumstantial clinical information, post mortem findings, pathophysiology (including complications andprogression of the disease to death) are discussed, highlighting the relevance of accurate and timely diagnosis and treatmentto avoid malpractice and mortality.info:eu-repo/semantics/publishedVersio

    Aiming at the search for a new alternative for the sustainability of the properties in the irrigated areas of the Brazilian Northeast, the objective of this study was to identify the ideal irrigation system and depth for a better yield and quality of pear fruits in the Sub-middle São Francisco region. The experiment was conducted in the commercial orchard of the Frutos do Sol farm, located in the municipality of Petrolina, PE, Brazil, from October 2016 to November 2017. The treatments consisted of four irrigation depths (60; 80; 100 and 120% of crop evapotranspiration -ETc), under two irrigation systems (drip and micro-sprinkler), in two crop cycles of ?Triunfo? pear. Yield, average fruit weight, water productivity, pulp firmness and titratable acidity, total soluble solids and lightness of the fruits were analyzed. Irrigation depths of 96.04% and 94.84% ETc promote, respectively, the highest marketable yields for the first (43.48 t ha-1) and second (26.55 t ha-1) cycle of ?Triunfo? pear in the Brazilian semi-arid region. Drip irrigation system in the warmer period promotes higher yield. The cultivation of ?Triunfo? pear irrigated by drip and micro-sprinkler promotes fruits with good commercial quality in the Brazilian semi-arid regio

    Gas exchange and post-harvest quality of Kent mango subjected to controlled water deficit in semi-arid region.

    Brazil is the seventh largest producer of mangoes in the world, and the São Francisco Valley is the main producing region, with ?Kent? as one of the main cultivars. Considering that irrigation management affects physiological events, production and fruit quality, the objective of this work was to evaluate the gas exchange in the leaves and fruit quality of ?Kent? mango subjected to controlled water deficit in the semi-arid region. The experiment was carried out in Petrolina-PE, semi-arid region of the São Francisco Valley. The experimental design used was randomized blocks, in a triple factorial scheme, with four irrigation depths (40, 60, 80 and 100% of crop evapotranspiration - ETc), three phenological stages (F1 - flowering, F2 - fruit growth, F3 - fruit maturation) and two production cycles (2018 and 2019), with four replicates. During the phenological stages, the physiological parameters of gas exchange were evaluated. After harvesting, the following parameters were evaluated: soluble solids content, titratable acidity, pH, firmness and peel color. Irrigation with a depth between 79.5 and 83.6% ETc during the evaluated stages promoted greater gas exchange in the leaves, greater firmness and acidity in the fruits. The reduction in irrigation depth in F1 and F3 reduced the soluble solids content, while in F2 the highest soluble solids content was obtained with irrigation between 68.24 and 74.5% ETc. The most suitable irrigation depth for ?Kent? mango cultivation depends on the purpose of the producer and on the phenological stage of the crop

    The objective of this study was to evaluate the influence of irrigation systems and water depths on physiological, biochemical and production processes of pear trees grown in the Brazilian semi-arid region. The experimental design was randomized blocks, with 2 × 4 factorial scheme, corresponding to two irrigation systems (drip and microsprinkler) and four irrigation depths (60, 80, 100 and 120% of the crop evapotranspiration - ETc), with four replicates. Water deficit and excess applied to plants are harmful to gas exchange as well as to biosynthesis and accumulation of carbohydrates, amino acids and proteins in leaves, compromising the cultivation cycle of pear plants grown in the Sub-Middle São Francisco region. The irrigation depth of 91.8% ETc promotes the highest production of pear (18.49 kg plant -1) under drip and microsprinkler irrigation systems, under the edaphoclimatic conditions of the Sub-Middle São Francisco region

    Considering the growing demand for mango to meet the national and international market and the competitiveness among the producing markets, the use of new products and management techniques that improve the potential production in the irrigated areas of the Brazilian northeast can be an important tool for the sustainability of its cultivation. In this context, the objective of the present study was to evaluate the effect of doses and periods of application of calcium from Lithothamnium seaweed via fertigation, in two production cycles of ?Palmer? mango in the Brazilian semiarid region. The experiment was conducted at the Saúde farm, located in the Projeto Senador Nilo Coelho N-09, in the city of Petrolina, PE, Brazil. The experimental design was randomized blocks, in a 5 × 4 × 2 factorial scheme, corresponding to five doses of Lithothamnium via fertigation (0, 5, 10, 15 and 20 L ha-1), four periods of application (30, 60, 90 and 120 days after flowering) and two production cycles, with three blocks, totaling 120 plots. The variables evaluated were: number of marketable fruits and parthenocarpic fruits per plant, average weight of marketable fruits and parthenocarpic fruits, and marketable fruit production. Application of 12 L per plant of calcium from Lithothamnium promotes a 20% increase in ?Palmer? mango yield in the Sub-middle São Francisco Valley. Calcium from Lithothamnium should be applied from the beginning up to 30 days after flowering of ?Palmer? mango in the Sub-middle São Francisco Valley. The effect of the application of calcium from Lithothamnium seaweed on ?Palmer? mango production varies according to doses and production cycles
