CAD/CAM technology-elaboration of electronic model through optical impression in the fabrication of the dental prostheses by a computer assisted device

In modern CAD/CAM technology of dental prosthetics, the "optical impression" taken by special video cameras deploying 3D-recording of the oral situation (Cerec 1, Cerec 2) initiates the computer-generated production of a digital model. The computer receives and renders the digital data obtained through "optical impression" i.e. data acquisition not as a "negative" of the oral situation but as a "positive" copy of it, namely as a digital model in a virtual environment which can be displayed on the screen and be further used in the fabrication of dental prostheses by means of a computer-assisted device (CAM or CIM).     

Paclitaxel in combination with weekly 24-hour infusional 5-fluorouracil plus leucovorin in the second-line treatment of metastatic breast cancer: Results of a phase II study

Purpose: To evaluate the antitumor activity in terms of response rate (RR), time to progression (TTP) and survival of paclitaxel in combination with weekly 24-hour infusional 5-fluorouracil (5-FU)/leucovorin in pretreated metastatic breast cancer (MBC).Patients and methods: Fifty-four patients with bidimensionally measureable disease were included during phase II. Thirty-two had anthracycline resistant disease. Treatment consisted of 5-FU (24-hour i.v. infusion) 2.0 g/m², leucovorin (two-hour i.v. infusion prior to 5-FU) 500 mg/m², weekly for six weeks (day 1, 8, 15, 22, 29, 36) and paclitaxel (three-hour i.v. infusion) 175 mg/m² was administered additionally on days 1 and 22, q 50 days.Results: We observed complete remissions in 4% of patients (2 of 54), partial remissions in 55% (30 of 54), stable disease in 37% (20 of 54) and progressive disease in 4% (2 of 54). The overall RR was 59% (95% CI 48%–72%). The RR in 32 patients with anthracycline resistant disease was 59% (19 of 32). The median duration of response was 12 months (3–22), median TTP eight months (2–22) and median survival time 15 months (2–28). Neutropenia was common, but of CTC grade 2 or 3 in most patients. Nonhematologic toxicities mostly consisted of CTC grade 1 and 2 myalgia, diarrhea, mucosits, nausea and vomiting.Conclusions: Paclitaxel combined with weekly 24-hour infusional 5-FU/leucovorin is well tolerated in the second line treatment of MBC. High efficacy was documented even in the treatment of anthracycline resistant disease, which warrants further evaluation.     

MATERNAL ANEMIA AND POSTPARTUM WEIGHT CHANGE ASSOCIATED WITH DECREASED MATERNAL-INFANT INTERACTION IN A RURAL KENYAN POPULATION

Associations between maternal nutritional factors including energy intake, body mass index, postpartum weight change, and anemia status and maternal-infant interactions were examined in 124 mother-infant pairs from a marginally malnourished, rural Kenyan population. Anemic mothers spent less time holding and caring for their infants than nonanemic mothers. Mothers who retained their pregnancy weight gain or were able to gain weight postpartum spent more time looking at their infants than mothers who lost weight postpartum. Maternal food intake per se was not associated with patterns of infant interaction. Lower birth weight infants were held more, cared for more, and looked at face-to-face more by their mothers. Older sisters tended to be more involved in infant interactions with higher birth weight infants.     

Long-term effects of neovaginal reconstruction with sigmoid loop technique on sexual function and self image in patients with gynecologic malignancies: results of a prospective study

ObjectiveWe evaluated the long-term results of sigmoid vaginoplasty in women with gynecologic malignancies after radical pelvic surgery, with specific focus on safety and effects of the procedure on patients' sexuality and self image.MethodsThis prospective study included women with gynecologic malignancies who underwent partial or complete colpectomy as part of the cancer treatment. In all cases a pedicled sigmoid loop was used for the neovaginal reconstruction. Systematic clinical examination was performed and validated questionnaires about sexuality (Female Sexual Function Index), quality of life (SF-12) and susceptibility to depression (ADSk-15) were answered by all patients at the earliest 6 months after vaginoplasty.ResultsSeven patients with sigmoid vaginoplasty, recruited between 11/2003 and 02/2008, were evaluated in the present analysis. Mean patients age was 48 ± 8.49 years. Mean neovaginal length was 6.4 cm (range: 2–12 cm). The mean Female Sexual Function Index (FSFI)-score of all patients was 16.6 ± 12.6. In the subset of sexually active patients the mean FSFI-score was 22.5 ± 9.4 higher. Regarding early operative morbidity and complications, sigmoid vaginal reconstruction appears to be a safe procedure, though in a long-term assessment 85% of the patients developed a vaginal stenosis with the need for operative bougienage.ConclusionsThe vaginal reconstruction using a sigmoid loop is a safe and well accepted procedure in patients with gynecologic malignancies. However lower sexuality scores seem to be achieved than in non-cancer patients after equivalent vaginoplasty. Cancer-related physical and psychological comorbidity seem to have negative effects on the overall outcome and patient's satisfaction.     

How important is consent in maternal serum screening for Down syndrome in France? Information and consent evaluation in maternal serum screening for Down syndrome: a French study

OBJECTIVES: To evaluate the level of information and informed consent for maternal serum screening (MSS) for Down syndrome (DS) in the second trimester of pregnancy and analyse the exercise of autonomy towards the test by the women concerned. METHODS: We studied the population of pregnant women attending obstetric consultations in two French hospitals over a 3-month period. The women were assigned to three groups according to MSS results for DS: women at high risk of having a child with DS (group 1), women at low risk (group 2) and women who did not undergo the test (group 3). A questionnaire was completed before the medical consultation, to assess the quality of consent before amniocentesis for the group at high risk and before the second-trimester ultrasound scan for the other two groups. RESULTS: We analysed 305 questionnaires for 89, 137 and 79 women belonging to groups 1, 2 and 3 respectively. In total, 123 women (40.3% [IC 95%, 35-46%]) were considered to be well informed; 33 (10%, [IC 95%, 8-12%]) had a high level of knowledge, but made choices not consistent with their stated attitude, and 149 (49.7% [IC 95%, 45-56%]) were considered uninformed. Logistic regression analysis showed that maternal consent depended on three independent components: The score attributed to the doctor for information about MSS (t = 4.216, p < 0.001).Whether the patient belonged to group 1 (t = -2.631, p < 0.009).Educational level (< high-school diploma, high-school diploma or at least two years of higher education after high school) (t = 2.324, p < 0.02). The rate of consent increased with educational level and was highest for the women in group 1 and for those whose doctor had a high information score. CONCLUSIONS: Our findings clearly show that women are provided with insufficient information concerning MSS screening for DS in the second trimester of pregnancy for real and valid consent to be obtained.
