Comparison of facial features in fetuses and newborns following natural delivery with cephalic presentation: a pilot study.

Background: Malocclusions are usually diagnosed around 3-4 years of age according to specific criteria. The purpose of this protocol is to validate a method to understand how the type of delivery can influence the development of malocclusions.

Materials: This pilot study, conducted at the Fondazione IRCCS Cà Granda Ospedale Maggiore Policlinico of Milan, evaluated the relationship between the type of delivery, fetal presentation, and the presence of malocclusions in children.

Microbiological Analysis of Plaque and Its Composition in Three Patient Groups under Different Orthodontic Treatments.

Background: This article analyzes differences in microbiological parameters and periodontal health conditions among three patient groups: those undergoing conventional orthodontic treatment with fixed appliances, patients undergoing orthodontic treatment with clear aligners, and a control group receiving no treatment.

Materials And Methods: In this study, 60 patients were enrolled. The microbiological analysis employed a qualitative and semi-quantitative methodology of bacterial morphotype analysis.

Accuracy of automated 3D cephalometric landmarks by deep learning algorithms: systematic review and meta-analysis.

Objectives: The aim of the present systematic review and meta-analysis is to assess the accuracy of automated landmarking using deep learning in comparison with manual tracing for cephalometric analysis of 3D medical images.

Methods: PubMed/Medline, IEEE Xplore, Scopus and ArXiv electronic databases were searched. Selection criteria were: ex vivo and in vivo volumetric data images suitable for 3D landmarking (Problem), a minimum of five automated landmarking performed by deep learning method (Intervention), manual landmarking (Comparison), and mean accuracy, in mm, between manual and automated landmarking (Outcome).

3D Cephalometric Normality Range: Auto Contractive Maps (ACM) Analysis in Selected Caucasian Skeletal Class I Age Groups.

Unlabelled: The objective of this paper is to define normal values of a novel 3D cephalometric analysis and to define the links through an artificial neural network (ANN).

Methods: One hundred and fifteen CBCTs of Class I young patients, distributed among gender-adjusted developmental groups, were selected. Three operators identified 18 cephalometric landmarks from which 36 measurements were obtained.

Cephalometric measurements performed on CBCT and reconstructed lateral cephalograms: a cross-sectional study providing a quantitative approach of differences and bias.

Background: Cephalometric analysis is traditionally performed on skull lateral teleradiographs for orthodontic diagnosis and treatment planning. However, the skull flattened over a 2D film presents projection distortions and superimpositions to various extents depending on landmarks relative position. When a CBCT scan is indicated for mixed reasons, cephalometric assessments can be performed directly on CBCT scans with a distortion free procedure.

[Hysteroscopic evaluation of the endometrium in 63 postmenopausal patients treated with tamoxifen for breast cancer].

This retrospective analysis intends to evaluate by histeroscopy the endometrial findings in a group of 63 patients in post-menopausal treated with tamoxifen for breast cancer. Our patients assumed tamoxifen for a different period between 6 and 120 months. Patients have been divided in two groups: I) patients undergoing hysteroscopy because of some clinical symptoms; II) patients who undergoing hysteroscopy as a routine examination.

Clinical stage IIb carcinoma of the uterine cervix: results in 122 patients.

122 patients affected by clinical stage IIb cervical carcinoma were referred to the Radiation Therapy Department and Obstetrics and Gynaecology Department of the University of Florence between 1977 and 1986 for either radiation therapy only (42 patients) or preoperative treatment followed by surgical resection (80 patients). Among the 42 patients receiving radiation therapy only 23 were treated with external beam therapy only (total dose ranging between 50 Gy and 70 Gy at the mid-plane of the pelvis) while 19 received an additional intracavitary boost (total dose ranging between 68 Gy and 98 Gy at Manchester point A). Higher doses of irradiation to point A were correlated with significantly improved survival (65% vs.

[Erythrocyte zinc-protoporphyrin content in pregnancy].

The assessment of iron deficiency represents a major aspect of routine laboratory chemico-clinical analysis, but the results provided by traditional hemato-clinical tests (sideremia, transferrinemia, mean cell volume and red blood cell levels) may not prove conclusive. During pregnancy iron deficiency is common and it would be extremely valuable to obtain a precise method of evaluating anemia. The assay of erythrocytic zincoprotoporphyrin (ZNPP) offers further diagnostic possibilities.

GnRH analogs in gynecological oncology: a review.

Chronic GnRH analogs (GnRH-A) administration has proven to be effective for the control of some hormone-dependent tumors. GnRH-A are now in the standard treatment of prostatic cancer. In the present paper experimental and clinical data on the use of GnRH-A in gynecologic oncology are reviewed in order to identify a possible role in the therapy of breast, endometrial and ovarian cancer.
