RESUMO
Objective: Evaluation of sexual dimorphism is a crucial concern for anthropologists, forensic scientists, and archaeologists. Teeth have been used as an alternative tool to determine sex in forensic anthropology. However, it is necessary to use data specific to a particular population, as different populations exhibit varying degrees of sexual dimorphism. This study aimed to determine the sexual dimorphism in the buccolingual dimensions of permanent anterior teeth in the young Iranian population. Materials and methods:A total of 100 students (50 females and 50 males) participated in the current study. A total of 1200 permanent anterior teeth were examined. The buccolingual dimension of all anterior teeth was measured using Vernier Calipers with a calibration of 0.01 mm. Data were analyzed using an independent sample T-test and paired sample T-test, and a P-value of less than 0.05 was considered statistically significant. Results:The mean values of the buccolingual dimension of the maxillary canines on the right and left sides (13, 23) were statistically greater in males than females (P=0.04, P=0.03) and had the greatest percentage of sexual dimorphism (4.08% and 5.26%, respectively). Conclusion:The buccolingual dimension of Iranian canines could be used as a reliable material to identify gender in forensic studies, and the degree of sexual dimorphism varies among different populations. Therefore, it is essential to use the relevant data samples for each population. It was concluded that Europeans had the greatest amount of sexual differences in the anterior teeth, while Iranians had the least amount of sexual dimorphism in the anterior teeth.
RESUMO
Introduction:Endometriosis is defined by the presence of endometrial tissue outside the uterus, therefore leading to a chronic inflammatory reaction, adhesions development, scar tissue and a distorted pelvic female anatomy, most of the times leading to female infertility. Kisspeptin represents a neuropeptide thought to have an essential role in the reproductive functions of both female and male patients. Recently, positive correlations with kisspeptins were noticed in patients diagnosed with endometriosis. Materials and methods: Our study was performed between January 2021-March 2022 in "Elena Doamna" Clinical Hospital of Obstetrics and Gynecology Iasi, Romania. It was a prospective case-control study and included two groups of patients. Both groups consisted in female patients aged between 18 and 45 years, with a body mass index (BMI) between 18,5-30 kg/m2 and similar medical data. Patients in the study group had primary or secondary infertility and endometriosis, while the control group consisted of women with no reproductive issues who had healthy regular menstruations and at least one child. All patients agreed to participate in our study and signed the consent form. Clinical examination, pelvic ultrasound and hormonal dosages were performed. We tested the levels of LH, FSH, kisspeptin, estradiol, prolactin, testosterone, insulin and the glycemic levels in both groups during the follicular phase of their menstrual cycle. Results: We managed to enroll eight patients with endometriosis in the study group and an equal number of patients in the control group. There were significant differences between serum kisspeptin levels, but not also between other hormonal dosages. All patients in the study group had medical evidences of endometriomas but none of them had been subjected to laparoscopy. Conclusion:When considering our study, we regarded the first attribution given to kisspeptin, the one of a metastasis suppressor, and concluded that the high serum values of kisspeptin in patients with endometriosis represented a compensatory-adaptive mechanism needed to constrain future spread of endometriomas in early stages of this pathology.
RESUMO
Background and Objectives: The multiple pregnancies associated with COVID-19 is a new and difficult condition to manage. The prognosis for rapid deterioration after the cesarean delivery is difficult to assess and needs close interdisciplinary follow-up due to pregnancy and postpartum-related changes. Materials and Methods: We report the case of a 37-year-old primigesta primipara patient who was admitted to "Elena Doamna" Clinical Hospital of Obstetrics and Gynecology at 33 weeks and 3 days of gestation with high-grade multiple pregnancies (triplets) for threatened premature birth associated with COVID-19. The patient had a history of surgically corrected atrial septal defect during childhood and currently is known to have paroxysmal supraventricular tachycardia. Tocolysis was ineffective and the decision to perform a cesarean operation was made. The diagnosis was established: primigesta, primipara, at 34 weeks of gestation, high-grade multiple pregnancy with triplets, intact membranes, threatened premature birth, surgically corrected atrial septal defect, paroxysmal supraventricular tachycardia, infection with COVID-19. The patient underwent a cesarean intervention and treatment for COVID-19 pneumonia. The intervention took place at 33 weeks and 4 days of gestation resulting in four newborns with weights between 1400 g and 1820 g and Apgar scores between 6-8. All newborns were transferred to a third-degree Neonatology ICU service due to their prematurity. The fourth newborn was not identified in any of the ultrasounds performed during pregnancy. During the postpartum period, the patient had a fulminant evolution of COVID-19 pneumonia, with rapid deterioration, needing respiratory support and antiviral treatment. Discussions: Managing high-risk obstetrical pregnancies associated with COVID-19 requires a multidisciplinary team consisting of obstetricians, anesthesiologists, neonatologists, and infectious disease doctors. Conclusion: Our case is the first to our knowledge in Romania to present an association of high-grade multiple pregancy with COVID19 moderate form, rapidly evolving postpartum, needing rapid intensive care admission, and specific treatment with Remdesivir, with good post-treatment evolution.

Aim:The present study aimed to investigate nurses' knowledge about the care provided to pre-eclamptic patients in a tertiary care centre in Romania. Study design:A cross sectional study. Setting:This study was conducted in Polizu Clinical Hospital of Obstetrics and Gynecology, Bucharest, Romania, from early January 2019 to the end of February 2019. Subjects:Sixty five nurses working at the Obstetrics and Gynecology Department. Data analysis:Data were collected using a self-administered structured questionnaire and they were analysed using IBM SPSS Statistics 20 and Microsoft Office Excel/Word 2013. Tools:Two tools were used for data collection. Tool I: Assessment sheet to collect data regarding nurses' general characteristics; and Tool II: A questionnaire to evaluate nurses' knowledge and practices regarding the management of pre-eclampsia/eclampsia. Results:About 73.8% of nurses confirmed that they participated in educational programs in the obstetrics field; 10.8% of them confirmed that they participated in training programs for pre-eclampsia/eclampsia, 47.7% gave the right answer when they were asked to correctly identify the definition of eclampsia, 78.5% answered correctly to the proper identification of proteinuria in pregnancy definition, only 9.2% gave the right answer when asked to properly identify chronic hypertension, 40% chose the right answer when asked to correctly identify gestation ages for antenatal use of corticosteroids to improve neonatal result, and 70.8% answered correctly to the proper identification of the best anticonvulsant for severe pre-eclampsia/ eclampsia. Conclusion:Continuous professional development is critical in nurses' work in both theory and clinical practice. Unfortunately, this study identified wide gaps in the knowledge of nurses about pre-eclampsia/ eclampsia, including their assessment, diagnosis and management. This is a major concern as globally, severe pre-eclampsia and eclampsia result in 70 000 maternal deaths annually. Recommendations:Improving nurse's awareness regarding nursing knowledge and practices through educational programs aimed to encourage them to use best evidence-based practices in their daily practice and reducing maternal and child mortality by pre-eclampsia/eclampsia in Romania.
RESUMO
Psoriasiform dermatoses represent a wide spectrum of inflammatory conditions, with several major forms represented by psoriasis, as the prototype of this category, followed by pustular psoriasis, Reiter's syndrome, pityriasis rubra pilaris, lichen simplex chronicus and large-plaques parapsoriasis. They create a diagnostic challenge, both clinical and histopathological, because of their complexity and frequent overlapping of the microscopical features. The characteristic histopathological features of psoriasiform reaction comprise extensive hyperkeratosis, with horizontally confluent but vertically intermittent parakeratosis, which alternate with orthokeratosis, thin granular layer, with relative frequent mitoses, uniform elongated and fused rete ridges, edematous superficial papillary dermis, with dilated capillaries, perivascular lymphocytic infiltrate, Munro's microabscesses, and spongiform pustules of Kogoj. Our paper aims to review the histopathology of major form of psoriasiform dermatoses and to emphasize the characteristic microscopical differences between them, for a better approach of the diagnosis as an important key for clinical and therapeutical management. Using the clinicopathological correlations, a thoroughly evaluation of the microscopical features and compartments distribution or special stainings and techniques, the range of differential diagnosis can be decreased and a more accurate diagnostic can be usually achieved. The insights into the pathogenic mechanisms can lead to new therapeutic opportunities targeted to the specific type of inflammatory lesion.
RESUMO
The early diagnosis of dental caries has an important role in pregnancy, as it allows establishing preventive measures. Besides the clinical examination, there are modern preclinical ways of detecting odontal lesions such as electrical conductivity (EC) and quantitative Light-Induced Fluorescence (QLF). Dental radiography and three-dimensional (3D) orthopantomography, although useful, are forbidden during pregnancy (6). Bacteriological evaluation and early detection of demineralized areas allow preventive measures aimed at stopping the destructive process and permit measures for the restoration of the damaged dental structures. Regarding the treatment of caries, superficial coronal odontal lesions in enamel can be treated noninvasively by remineralization. Reconstruction, obturation or inscruction therapy involves loss of dental material, sometimes even healthy one; they are also expensive and stressful for the patient and therefore, remineralization and sealing of dental retention areas is the treatment of choice for children and pregnant women (8). For the restoration of the damaged dental structure, fluoride topics, laques or fluoride gels are applied locally (3). An adequate diet during pregnancy plays an important role in maintaining the general and oral health; it must be high in calories, proteins, vitamins and minerals, and it must have a balanced proportion of salts, carbohydrates and lipids. As with the rest of the population, proper dental brushing at least twice a day in the morning and evening as well as the use of yarn thread are effective ways of oral hygiene, which also prevent the appearance and evolution of dental caries (1).
RESUMO
The aim of this exploratory research is to capture spatial evolution patterns in the Bucharest metropolitan area using sets of single polarised synthetic aperture radar (SAR) satellite data and multi-temporal radar interferometry. Three sets of SAR data acquired during the years 1992-2010 from ERS-1/-2 and ENVISAT, and 2011-2014 from TerraSAR-X satellites were used in conjunction with the Small Baseline Subset (SBAS) and persistent scatterers (PS) high-resolution multi-temporal interferometry (InSAR) techniques to provide maps of line-of-sight displacements. The satellite-based remote sensing results were combined with results derived from classical methodologies (i.e., diachronic cartography) and field research to study possible trends in developments over former clay pits, landfill excavation sites, and industrial parks. The ground displacement trend patterns were analysed using several linear and nonlinear models, and techniques. Trends based on the estimated ground displacement are characterised by long-term memory, indicated by low noise Hurst exponents, which in the long-term form interesting attractors. We hypothesize these attractors to be tectonic stress fields generated by transpressional movements.
RESUMO
Polycystic ovary syndrome is a common endocrinopathy characterized by oligo ovulation or anovulation, signs of androgen excess and multiple small ovarian cysts. It includes various metabolic abnormalities: insulin resistance, hyperinsulinemia, impaired glucose tolerance, visceral obesity, inflammation and endothelial dysfunction, hypertension and dyslipidemia. All these metabolic abnormalities have long-term implications. Treatment should be individualized and must not address a single sign or symptom. Studies are still needed to determine the benefits and the associated risks of the medication now available to practitioners.

Congenital disorders of glycosylation (CDG) comprise a clinically and biochemically heterogeneous group of monogenetic-inherited, multisystemic diseases that affect the biosynthesis of N- and/or O-glycans linked to glycoconjugates. Recently, we identified the first patient with a defect in the cytosolic-orientated GDP-mannose:Man(3-4) GlcNAc(2)-PP-dolichol alpha-1,2-mannosyltransferase (ALG11), who presented an accumulation of shortened dolichol-linked oligosaccharides leading to CDG-Ip (ALG11-CDG). Here we describe an improved metabolic labeling method that allowed the identification of three new CDG-Ip cases that were missed so far in routine diagnostics. Although all CDG-Ip patients carry different mutations in the ALG11 gene, they share a variety of clinical syndromes like an unremarkable prenatal period followed by developmental delay, psychomotor, and mental retardation, strabismus convergens and seizures occurring in the first year of life.

Congenital disorder of glycosylation-Ia (CDG-Ia, also known as PMM2-CDG) is caused by mutations in the gene that encodes phosphomannomutase 2 (PMM2, EC 5.4.2.8) leading to a multisystemic disease with severe psychomotor and mental retardation. In a hypomorphic Pmm2 mouse model, we were able to overcome embryonic lethality by feeding mannose to pregnant dams. The results underline the essential role of glycosylation in embryonic development and may open new treatment options for this disease.

Modification of glycoproteins by the attachment of fucose residues is widely distributed in nature. The importance of fucosylation has recently been underlined by identification of the monogenetic inherited human disease "congenital disorder of glycosylation IIc," also termed "leukocyte adhesion deficiency II." Due to defective Golgi GDP-fucose transporter (SLC35C1) activity, patients show a hypofucosylation of glycoproteins and present clinically with mental and growth retardation, persistent leukocytosis, and severe infections. To investigate effects induced by the loss of fucosylated structures in different organs, we generated a mouse model for the disease by inactivating the Golgi GDP-transporter gene (Slc35c1). Lectin binding studies revealed a tremendous reduction of fucosylated glycoconjugates in tissues and isolated cells from Slc35c1(-/-) mice. Fucose treatment of cells from different organs led to partial normalization of the fucosylation state of glycoproteins, thereby indicating an alternative GDP-fucose transport mechanism. Slc35c1-deficient mice presented with severe growth retardation, elevated postnatal mortality rate, dilatation of lung alveoles, and hypocellular lymph nodes. In vitro and in vivo leukocyte adhesion and rolling assays revealed a severe impairment of P-, E-, and L-selectin ligand function. The diversity of these phenotypic aspects demonstrates the broad general impact of fucosylation in the mammalian organism.
