- ItemSomente MetadadadosExtraoral Implants for Anchoring Facial Prostheses: Evaluation of Success and Survival Rates in Three Anatomical Regions(Quintessence Publishing Co Inc, 2017) dos Reis, Heitor Batista; Piras de Oliveira, Joaquim Augusto [UNIFESP]; Pecorari, Vanessa Arias; Raoufi, Shiva; Abrahao, Marcio [UNIFESP]; Dib, Luciano LauriaPurpose: The aim of this study was to evaluate the success and survival rates of extraoral implants for the fixation of facial prostheses in three anatomical regions. Materials and Methods: Subjects were consecutive patients with facial defects who underwent implant placement by the same surgeon in the orbital, nasal, and auricular regions between 2003 and 2012. After a minimum of 4 months of osseointegration, prostheses were anchored to the implants, and the patients were monitored for 11 to 111 months. Success rate, implant survival time, and occurrence of previous radiotherapy were evaluated. Rate of implant survival was estimated as a function of the anatomical region of the three groups (orbital, nasal, or auricular), and confidence intervals were calculated using Kaplan-Meier analysis with alpha = .05. Results: In the 68 patients' 138 fixed implants, 48 showed defects in the orbital, 9 in the nasal, and 11 in the auricular region. The success rates and survival times were 95.9% and 8.6 years for the orbital, 92.9% and 2.8 years for the nasal, and 92% and 9.0 years for the auricular region, respectively. The success rate of implants in previously irradiated regions was 90.3% for the orbital and 100% for the auricular region. None of the patients was irradiated in the nasal region. Conclusion: No significant differences in implant success or survival were observed with regard to anatomical region or previous irradiation.
- ItemSomente MetadadadosFactors associated with survival of very-low-birth-weight infants in a Brazilian fee-paying maternity in the 1990s(Oxford Univ Press, 2007-06-01) Bernardes de Mello, Filomena; Branco de Almeida, Maria Fernanda; Dos Santos, Amelia Miyashiro [UNIFESP]; Paula Fiod Costa, Helenilce de; Miyoshi, Milton Harumi; Amaro, Eduardo Rahme; Universidade Federal de São Paulo (UNIFESP); Santa Joana Hosp & MaternThis study describes intra-hospital survival rates of very-low-birth-weight infants, as well as factors present at birth associated with survival, during a period of 10 years. This is a Retrospective cohort study performed in a 3rd level nursery at Santa Joana Maternity Hospital, a fee-paying institution in São Paulo, Brazil. From January 1991 to December 2000, 963 live-born infants with a birth weight of 500-1499 g, without congenital anomalies, were followed until discharge. Survival was studied according with year of birth, and stratified by birth weight and gestational age. Factors present at birth associated with survival were analyzed by logistic regression. Patient characteristics were: birth weight 500-999 g (38%), gestational ages <= 27 weeks (32%), prenatal care (100%), small for gestational age (39%), multiple gestation (22%), male (52%) and C-section (68%). According to birth weight 500-749, 750-999, 1000-1249 and 1250-1499 g, survival rate in 1991 was, respectively, 0, 6,60 and 80% and increased to 15, 71, 93 and 96% in 2000. Regarding gestational age of 24-25 weeks, 26-27 weeks and 28-31 weeks, intra-hospital survival in 1991 was 0, 0 and 57%, and in 2000, improved to 44, 74 and 82%. Survival was associated with increasing birth weight (OR 0.996; CI 95%: 0.995-0.997) and gestational age (OR 0.73; CI 95%: 0.67-0.80), female gender (OR 1.52; CI 95%: 1.04-2.22) and year of birth (OR 0.70; CI 95%: 0.65-0.76). in the 1990s, survival rates among very-low-birth-weight infants improved according to year of birth, mainly in female patients with birth weight >= 750 g, and gestational age >= 26 weeks.
- ItemAcesso aberto (Open Access)Laparoscopic left lateral segmentectomy for metachronic metastases of small intestine adenocarcinoma: a case report(Sociedade Brasileira de Coloproctologia, 2011-12-01) Pais-costa, Sergio Renato [UNIFESP]; Araujo, Sergio Luiz Melo; Lima, Olímpia Alves Teixeira; Paes, Marcio Almeida; Martins, Sandro José; Universidade Federal de São Paulo (UNIFESP); Hospital Santa Lucia; Universidade de Brasília (UNB); Hospital de Base do Distrito Federal; Universidade de Brasilia (UNB)Hepatectomy has been the standard treatment for metachronic metastases of non-colorectal (NCR) origin, mainly when the disease-free interval is more than two years. Laparoscopic hepatectomy has become the golden standard mainly for left side resections, due to lower morbidity, shorter hospital stay, early recovery and good cosmetic outcome. The authors report the case of a female patient with two metachronic metastases (ten years of disease-free survival), of non-colorectal origin (adenocarcinoma of small intestine), treated by laparoscopic left lateral segmentectomy (left hepatic lobectomy) with success. The postoperative progress was satisfactory. To date, the patient has presented no tumoral recurrence (six months of follow-up period). Laparoscopic left lateral segmentectomy can be satisfactorily performed in selected cases of hepatic metastasis. This approach presents low morbidity and good cosmetic result. The lack of alternative treatments and the poor prognosis of untreated cases have justified surgical resection in order to increase overall survival. Nevertheless, this approach should be performed by hepatic surgery expertise teams trained on advanced laparoscopic procedures.
- ItemSomente MetadadadosLiver retransplantation: A model for determining long-term survival(Lippincott Williams & Wilkins, 2006-04-15) Linhares, M. M.; Azoulay, D.; Matos, D.; Castelo, A.; Trivino, T.; Goldenberg, A.; Castaing, D.; Adam, R.; Delvart, V; Ichai, P.; Saliba, F.; Lemoine, A.; Samuel, D.; Bismuth, H.; Universidade Federal de São Paulo (UNIFESP); Hop Paul Brousse; Univ Paris SudBackground. Because of the worse results from retransplantation in relation to the initial liver transplantation, there is a need to refine the indication for retransplantation, such that fair distribution of this benefit is obtained.Methods. This was a Study of 139 patients who underwent liver retransplantation. Thirty variables were studied: 18 relating to the recipient and 12 to the donor. All the independent variables were initially compared with the length of survival using univariate analyses. Variables presenting significance were compared with the dependent variable of length of survival, to determine which factors were related to longer survival among patients, when evaluated together.Results. A multivariate model for determining long-term survival among patients with retransplants was built up using the following variables: recipient's age, creatinine, urgency of retransplantation and early failure of the first graft. Through this multivariate model it was possible to determine a score that was categorized according to tertile distributions (below the 33rd percentile, score < 24; 33rd to 66th percentile, 24 <= score <= 32; above the 66th percentile, score > 32). One-year, 3-year, and 5-year patient survival rates following retransplantation were respectively 85%, 82%, and 77% for scores < 24; 69%, 66%, and 61% for scores between 24 and 32; and 21%, 19%, and 16% for scores > 32 (P < 0.0001).Conclusion. the variables of recipient's age, creatinine, urgency of retransplantation, and early failure of the initial transplantation were factors that were independently related to the long-term survival of patients with liver retransplants.
