Statistical Aspects of Partial Edentulism in a Sample of Adults in Craiova, Romania.

The purpose of the study was to analyze the prevalence of different forms of partial edentulism and the description of the various parameters associated with this disease. Materials and Methods. The study was conducted on a total of 204 subjects who presented themselves at the Clinic of Dental Prosthetics and Oral Rehabilitation Clinic of the Faculty of Dentistry Craiova between October 2015 and June 2016. Results. Of the 204 subjects diagnosed with partial edentulism, 51.47% belonged to the age group of 20-29 years, 52.46% were female and 82.84% came from the urban environment. The most frequent cause of the edentulism was dental caries and their complications. The present study has shown that the partial edentulism forms encountered, especially those of the Kennedy III class, had an increased frequency among the young population, especially in the maxillary arch.

First Trimester Ultrasound Diagnosis of Right Aortic Arch (RAA).

OBJECTIVES: In the present research we proposed to evaluate the cases diagnosed in the first trimester of pregnancy by ultrasound with RAA, knowing the fact that although, in most cases the disease is isolated and asymptomatic, in some cases the presence of RAA can be associated with other fetal structural abnormalities that must be detected and monitored during pregnancy. We established correlations between the postnatal or anatomopathological examination (in cases ended by therapeutic abortion) and the presence of RAA detected in the first trimester. MATERIAL AND METHOD: We conducted a retrospective analytical study that investigated the role of the RAA early detection (isolated or associated with other cardiac abnormalities) for a correct pregnancy monitoring and postpartum management. Between 2012 and 2018, patients admitted in the first Obstetrics and Gynecology Clinic-the Prenatal Diagnostic Unit-of the Emergency County Hospital from Craiova, were evaluated in the first trimester of pregnancy for genetic abnormalities and early morphology. The study material was represented by the patient's medical records (observation sheets, surgical protocol records, anatomopathological diagnostic records). The obtained information was stored in Microsoft Excel files and statistically processed. RESULTS: During the study period, 14 cases with right aortic arch were diagnosed in the first and second trimester of pregnancy. 4 cases were detected in the first trimester: 2 cases (50%) presented left ductus arteriosus (DA)-RAA type 2 ("U" sign) and 2 cases (50%) presented right DA-RAA type 1 (mirror image-"V" sign). RAA type 1 associated Tetralogy of Fallot in one case (25%) and in another one case (25%) the anomaly was isolated. RAA type 2 associated atrio-ventricular septal defect (AVSD) in one case (25%) and in another one case (25%) the anomaly was isolated. There were no fetal extracardiac structural abnormalities associated with the RAA diagnosis in the first trimester. CONCLUSIONS: Over a seven years study period (2012-2018), 14 cases with RAA in the first and second trimester of pregnancy were detected. In the low-risk pregnancies group, the first trimester incidence of the RAA was 0.11% and the association of congenital heart abnormalities was 50%.

Prosthetic Treatment Possibilities for Extended Partially Edentulous and Completely Edentulous Patients, Depending on the Clinico-Morphological Characteristics of the Oral Mucosal Substrate.

The number of partially and completely edentulous patients requiring removable prosthetic treatment has increased constantly and denture wearers often have an associated oral status pathology. The purpose of this article is to present removable prosthetic treatment options that we chose for the extended partially edentulous and completely edentulous patients who required prosthetic rehabilitation treatment. We conducted this study on 52 extended partially edentulous and completely edentulous patients. We recorded in the examination chart the characteristics of the mucosal membrane covering the denture supporting structure and the peripheral structures and we performed a statistical analysis using Microsoft Excel. The prosthetic treatment phases were individualized according to morphological characteristics of the oral mucosal substrate.

Genetic evidence of multiple transmissions of HIV type 1 subtype F within Romania from adult blood donors to children.

We studied the phylogeny of HIV-1 subtype F viruses from children and adults in Romania in order to (1) clarify whether the Romanian subtype F epidemic was caused by one or several virus introductions and (2) gain insight into the route of spread of the HIV-1 subtype F virus among children and adults in Romania. env (V3), gag (p17/half p24), and pol (prot/half RT) sequences were obtained from three districts in Romania: Tirgu Mures (n = 9, children), Craiova (n = 15, children), and Bucharest (n = 13, adults). Of 37 HIV V3 sequences from Romania, 35 belonged to the genetic subtype F in the neighbor-joining tree, whereas 2 sequences from adults clustered with subtypes A and C. Within the subtype F cluster, no bootstrap-supported subclusters were observed according to geographic area in Romania. Two of the adult V3 sequences that clustered with the children were obtained from individuals who tested HIV seropositive in 1989 and 1990, showing that the subtype F virus was present among adults when the HIV epidemic began among children in Romania. The HIV-1 subtype F viruses obtained from children showed a mean pairwise V3 nucleotide distance of 7.9% and maximum distances of between 18 and 19%; both are higher than previously described. The mean V3 distances (overall, synonymous, and nonsynonymous) were significantly higher for adults than for children. One V3 sequence from the Democratic Republic of Congo clustered within the Romanian sequences, suggesting that the subtype F virus in Romania may originate from this area. Our data also suggest that HIV-1 subtype F was present among Romanian adults before it appeared in 1989 among institutionalized children. The juvenile population was most likely infected with the HIV-1 subtype F virus on more than one occasion, presumably through HIV-contaminated blood (products) obtained from adults.

Heidelberg Retina Tomography analysis in optic disks with anatomic particularities.

Due to its objectivity, reproducibility and predictive value confirmed by many large-scale statistical clinical studies, Heidelberg Retina Tomography has become one of the most used computerized image analysis of the optic disc in glaucoma. It has been signaled, though, that the diagnostic value of Moorfieds Regression Analyses and Glaucoma Probability Score decreases when analyzing optic discs with extreme sizes. The number of false positive results increases in cases of megalopapillae and the number of false negative results increases in cases of small size optic discs. The present paper is a review of the aspects one should take into account when analyzing a HRT result of an optic disc with anatomic particularities.

Detection of genetically diverse human immunodeficiency virus type 1 group M and O isolates by PCR.

A panel of 136 genetically diverse group M and 5 group O adult isolates from outside the United States and Europe were evaluated by PCR with the Roche AMPLICOR HIV-1 test, a modified version of the AMPLICOR HIV-1 test, and a new primer pair/probe system. Detection of some of these isolates was less efficient with the AMPLICOR HIV-1 test; however, the assay was significantly improved by reducing the sample input and lowering the annealing temperature. The new primer pair/probe set detected 140 of 141 isolates, including the 5 group O isolates that were not detected with either of the AMPLICOR HIV-1 test formats.
