The Use of Lactide Polymers in Bone Tissue Regeneration in Dentistry-A Systematic Review.

(1) Background: Different compositions of biodegradable materials are being investigated to successfully replace non-resorbable ones in bone tissue regeneration in dental surgery. The systematic review tried to address the question, "Can biodegradable polymers act as a replacement for conventional materials in dental surgery procedures?" (2) Methods: An electronic search of the PubMed and Scopus databases was conducted in October 2022. The following keywords were used: (lactide polymers) and (hydroxyapatite or fluorapatite) and (dentistry) and (regeneration).

Ischemic postconditioning reduces infarct size and microvascular obstruction zone in acute ST-elevation myocardial infarction - a randomized study.

Introduction: Ischemic postconditiong (postcon) has been reported to reduce infarct size in ST-segment myocardial infarction (STEMI). However, recently a few other studies did not show any effect of postcon or suggested that it may even be harmful.

Aim: We sought to assess whether postcon could reduce infarct size (IS) and the microvascular obstruction (MVO) zone in early presenters with STEMI.

Postconditioning attenuates early ventricular arrhythmias in patients with high-risk ST-segment elevation myocardial infarction.

Background: It has been demonstrated that postconditioning (postcon), brief episodes of ischemia during reperfusion period, in patients with ST-segment elevation myocardial infarction (STEMI) confers protection against ischemia-reperfusion injury and as a result, postcon might reduce infarct size. However, whether postcon may exert its beneficial effect on STEMI patients by reducing the occurrence of early malignant ventricular arrhythmias (VA) is still unknown. The aim of the study was to evaluate the influence of postcon on the presence of VA in early presenters with high-risk STEMI treated with primary coronary intervention (PCI).

The role of bioactive lipids in the development of soft tissue sarcomas in children – a review article.

Soft tissue sarcoma accounts for almost 7% of all malignant tumours in children and adolescents. This heterogeneous group of mesenchymal and neuroectodermal tissue neoplasms can be characterized by common biological and clinics traits. Bioactive lipids are described as lipids, the levels of which – when changed – lead to changes in cell functioning.

Postconditioning reduces enzymatic infarct size and improves microvascular reperfusion in patients with ST-segment elevation myocardial infarction.

Objectives: Postconditioning has been reported to reduce infarct size in ST-segment myocardial infarction (STEMI). However, recently, few other studies did not show any effect of postconditioning and suggested that it may be even harmful. We sought to assess whether postconditioning could reduce infarct size and improve myocardial reperfusion in early presenters with STEMI.

Estimation of vascular endothelial growth factor and placental growth factor serum levels' in infant with hemangioma and population of healthy infants.

Introduction: Hemangioma is found in approximately 10% of infants as the most prevalent benign neoplasm. The natural history of hemangioma is typical for this lesion and includes two phases: fast growth during the first year of life of the child and subsequent slow regression lasting some five years. Even though the etiopathogenesis of hemangioma has not been fully elucidated, the role played in this process by vascular growth factors remains unquestionable.

[Impact of L-thyroxine replacement therapy on pituitary changes secondary to congenital primary hypothyroidism--three cases report].

The aim of the study was an evaluation of the impact of L-thyroxine substitution therapy on the size and structure of the pituitary gland using MRI in three patients with pituitary hyperplasia or tumor secondary to primary congenital hypothyroidism. Along with imaging studies (MRI, skull X-rays) all patients had performed hormonal tests. All hormones (except adrenocorticotropic hormone) of anterior pituitary lobe were measured in basal condition, and some of them (GH, PRL) after stimulation tests, which showed hyperprolactinemia in one case and pituitary somatotropin insufficiency in the other.

[Magnetic resonance imaging and hormonal profile of the pituitary gland in patients with primary congenital hypothyroidism].

Unlabelled: The aim of our study was an estimation of the size and structure of the pituitary gland using MRI and the estimation of hormonal profile of the pituitary anterior lobe (except for ACTH) in 21 adult patients with congenital primary hypothyroidism.

Material And Methods: The studied group was divided into 2 subgroups: A--with normal level of serum TSH and B--with its elevated. The MRI showed pituitary hyperplasia or tumor in 28.

[Cantrell's pentalogy--a case report].

Pentalogy of Cantrell is a rare multiple congenital malformation syndrome characterized by a combination of features: a midline supraumbilical abdominal wall defect, a defect of the lower sternum, a defect of the diaphragmatic pericardium, deficiency of the anterior diaphragm, and congenital cardiac anomalies. This congenital defects could be diagnosed as early as in the first trimester of pregnancy. The complexity of this anomaly especially coexistent heart defects, determines the way and order of surgical treatment and commonly is a prognostic factor.

[Primary hyperparathyroidism in patient with thyroid papillary cancer--case report].

Patient with primary hyperparathyroidism and papillary thyroid cancer was presented. The female patient, 45 years old, because of papillary thyroid cancer was treated in the typical way by total strumectomy with lymphadenectomy following by 1131 therapy and L-thyroxine suppressive therapy. After 9 years, during one of control routine examinations, the serum levels of calcium and parathormone were increased (Ca2+: 1.

[Analysis of changes in peripheral and central nervous system in irregularly treated adult patients with primary congenital hypothyroidism].

Unlabelled: Lack of thyroid hormones in the womb and the first years of life causes changes in the nervous system and mental retardation. The aim of the study was to assess changes in peripheral and central nervous system in 29 adult patients with primary congenital hypothyroidism (PCH) depending on the cause of the disease and systematic treatment of L-thyroxine.

Material And Methods: The analysis was performed in 29 adult patients with PCH (16 women, 13 men) on the basis of the results of neurological examination, EEG, SPECT (Computer tomography single photon emission) of the brain.

[Intrauterine intestinal volvulus].

Intrauterine intestinal volvulus is an extremely rare case of acute congenital intestinal obstruction. The diagnosis is usually possible in the third trimester of a pregnancy. Fetal midgut volvulus is most likely to be recognized by observing a typical clockwise whirlpool sign during color Doppler investigation.

[Intralesional corticosteroid therapy in infantile hemangiomas].

Introduction: This study was undertaken to evaluate the effectiveness of intralesional corticosteroid therapy in infantile hemangiomas.

Material And Methods: The study was done in 38 patients aged 1 month to 14 years with infants accounting for 84% of all patients. Physical investigation was carried out before and after treatment.

[Biologically active compounds of edible mushrooms and their beneficial impact on health].
