We evaluated information regarding preoperative evaluation, the surgical anesthetic procedure, the patient's evolution during the hospital admission days and information pertaining to admission at another institution, which are related to unplanned hospital admission.In the period between January 1998 and June 2010, 129,850 procedures were analyzed retrospectively and found 49 cases (0.038%) of unplanned admissions. A diagnostic laparoscopy, colonoscopy and hysteroscopy with or without laparoscopic procedures were more determined to hospital admissions in absolute numbers. The main reasons for hospitalization were bleeding (32.7%) and pain (16.3%). Anesthesia time and body mass index were higher among patients who had unplanned hospital. The ASA III had a higher incidence of hospitalization, being hospitalized in intensive care unit (ICU). Patients undergoing otorhinolaringologic surgery and pediatric surgery had a higher incidence of hospitalization, and those undergoing ophthalmic and coloproctology surgery had higher incidence of hospitalization in ICU.The incidence of unplanned...

Este estudo tem como objetivo a análise retrospectiva de quatrocentos e oitenta e nove prontuários de pacientes que apresentaram fraturas do osso mandibular, pertencentes ao Serviço de Cirurgia e Traumatologia Buco-Maxilo-Faciais da Faculdade de Odontologia de Ribeirão Preto (FORP/USP) provenientes de atendimentos realizados no período compreendido entre agosto de 2002 e julho de 2012. A análise foi direcionada a dados relativos a variáveis populacionais como idade, gênero, cor e profissão. Também foram analisados os exames de imagem solicitados, vícios, etiologia, sinais e sintomas, classificação da fratura, fraturas associadas de face ou não, abordagem, tratamento, tempo para intervenção cirúrgica e internação, além do período de acompanhamento e complicações. O critério para a inclusão dos prontuários na amostra foram de apresentarem fratura de mandíbula, com preenchimento completo de informações e de possuírem o Termo de Consentimento Livre e Esclarecido. Como critérios de exclusão, foram desconsiderados os prontuários com preenchimento incompleto das informações e que não possuiam o Termo de Consentimento Livre e Esclarecido assinado. Os dados coletados por um único examinador foram transportados para uma planilha eletrônica utilizando o programa Microsoft Excel sendo realizada neste momento uma análise descritiva dos resultados obtidos. Tabelas e gráficos foram utilizados para a apresentação e interpretação destes dados. Concluimos que houve prevalência do gênero. / The aim of this study was to retrospectively analyse four hundred and eighty-nine patients files presenting fractures of the mandibular bone, incident from attendances at the Department of Traumatology and Maxillofacial Surgery, from the School of Dentistry of Ribeirão Preto (FORP/USP) during the period between August 2002 and July 2012. The analysis was directed through population data variables such as age, gender, race and profession. Imaging tests requested, addictions, etiology of trauma, signs and symptoms, fractures classification, associated fractures, approach, treatment, time to surgical intervention and hospitalization, apart from follow-up period and complications were also analyzed. The criterion for inclusion of records in the sample were experiencing jaw fracture with complete filling of information and having the Term of Consent. Exclusion criteria were disregarded the charts with incomplete filling of information and lacked the Term of Consent signed. The data collected by a single observer were transported to a spreadsheet using Microsoft Excel program currently being conducted to a descriptive analysis of the results. Tables and graphs were used for the presentation and interpretation of these data. We conclude that there was a prevalence of male gender, white race, aged between 21-30 years with fractures of the left side, unilateral, etiology traffic accident. Most fractures were treated surgically, intraoral access were prevalent and complication rates were low.

<p>Background: This is a retrospective study of patients treated with stereotactic body radiation therapy (SBRT) with the stereotactic body frame for centrally located lung tumours. The purpose was to investigate the doses to the different structures of the tracheobronchial tree and to relate these doses to the incidence of atelectasis. The goal was to estimate a tolerance dose for the bronchi. Materials: The patient material consisted of 71 patient treated at the Karolinska University Hospital for a total of 102 tumours between November 1993 and March 2004. The patient group consisted of 36 men and 35 women with a mean age at the treatment of 67 years (range 34-87). The group was a mixture of patients with primary lung cancer and pulmonary metastases. Methods: After rereading and reactivating the dose plans for the patients in the treatment planning system (TPS) the different tracheobronchial structures (trachea, right mainstem bronchus, right superior bronchus, right intermedius bronchus, right medius bronchus, right inferior bronchus, left mainstem bronchus, left superior bronchus, left intermedius bronchus, left inferior bronchus) were outlined. The dose distribution in each structure was calculated and a dose-volume histogram (DVH) was created. Patients were allocated to four groups, i.e. patients with right sided tumours (22), left sided tumours (14), mediastinal tumours (23) and bilateral tumours (10). After that the maximum and mean doses to all structures were analysed. An oncologist reviewed the medical records for the patients and especially looked for atelectasis. The doses were related to the incidence of atelectasis.</p><p>Results and Conclusions: For the patient group with right sided tumours it seems like the maximum doses to the bronchi are higher for the patients with atelectasis in comparison with patients without atelectasis. A better correlation between atelectasis and maximum doses rather than mean doses was observed for these patients. At this moment the results are too preliminary, so it is not possible to suggest a tolerance dose for the bronchi. What can be said is that the maximum doses to the bronchi for patients with right sided tumours without atelectasis are below 250 Gy3 expressed in biologically equivalent dose (BED) with α/β=3Gy, while at least one bronchi structure in the atelectasis patients received a maximum dose above 250 Gy3.</p>

<p>Background: Stereotactic body radiation therapy (SBRT) is a relatively new method which has been employed e.g. in the treatment of liver tumours. Little dosimetric data has been published for SBRT in the liver. The aim of this retrospective study was to quantify the dosimetric parameters that influence the toxicity of the healthy liver, and the effect on the tumour, for SBRT to liver tumours in patients treated at Karolinska University Hospital. A comparison was made to relating published studies.</p><p>Patients and Methods: The patient group to be studied were treated at Karolinska University Hospital for liver metastases with SBRT between July 1993 and October 2004. There were 64 patients treated with 71 treatment plans for 81 tumours. Differential dose volume histograms were collected for the clinical target volume (CTV), the planning target volume (PTV) and the liver excluding the CTV, from all dose plans. Since different fractionation schedules were used, the doses were normalised using the linear quadratic model, to be comparable. The doses to the uninvolved liver were evaluated with the mean liver dose, the Lyman-Kutcher-Burman (LKB) effective volume normal tissue complication probability (NTCP) model as well as the critical volume NTCP-model. A comparison was made to the studies of Dawson et al (2002) and Schefter et al (2005). The doses to the CTV were evaluated using the equivalent uniform dose tumour control probability (TCP) model, and related to target size and date of treatment.</p><p>Results: When the mean doses to the uninvolved liver (the liver volume without tumour tissue) were compared to Dawson and Ten Haken’s results (2005), 20 treatments out of 71 were predicted to give a risk of radiation induced liver disease (RILD) higher than 50%. The effective volume calculations predicted that 18 treatments gave a risk of RILD higher than 50%, when compared to the results of Dawson et al (2002). According to the critical volume model and the parameter values of Schefter et al (2005), our data predict that 10 of the treatments gave a risk of liver function failure, to an unspecified risk level. Treatments of large tumours resulted in higher doses to the liver. The doses to the CTV showed that the maximum prescribed dose decreased with increasing CTV.</p><p>Discussion and Conclusions: An evaluation of clinical data is necessary to make a full analysis of the treatments of this study.

Aproximadamente 40% dos casos de Linfoma não Hodgkin (LNH) se originam fora dos linfonodos, sendo então denominados linfomas extralinfonodais. No trato gastrointestinal (TGI), o estômago é o local mais freqüentemente envolvido, representado pelo linfoma MALT e pelo linfoma difuso de grandes células B (LDGCB). No Brasil, apesar da sua freqüência e importância, existem poucos dados epidemiológicos em relação aos linfomas, especialmente no que se refere aos linfomas de origem extralinfonodal. Para avaliar as características dos linfomas primários gástricos em uma população brasileira, 60 casos foram avaliados retrospectivamente. Trinta e oito (63,3%) foram classificados como LDGCB e 22 (36,6%) como MALT. Entre os dois grupos, não houve diferenças significativas em termos de sexo, idade, sintomas dispépticos, sintomas B, presença de massa Bulky, infiltração de medula óssea, estádio, infecção por H. pylori, achados laboratoriais e endoscópicos. Foram adotados diferentes protocolos de tratamento. A taxa de remissão completa foi de 73,1% no LDGCB e de 95% no linfoma MALT. A taxa de sobrevida livre de doença em 7 anos foi de 84,8% no LDGCB e de 94,1% no linfoma MALT. A taxa de sobrevida global em 7 anos foi de 65,7% no LDGCB e de 92,9% em 5 anos no linfoma MALT. Como não conseguimos demonstrar diferenças entre os dois tipos histológicos, concluímos que o diagnóstico histológico correto é essencial para a terapêutica mais adequada. / Approximately 40% of the non-Hodgkins Lymphoma arises outside lymph node tissue, being then termed extranodal lymphoma. In the gastrointestinal tract, gastric is the commonest localization represented by MALT and diffuse large B-cell lymphoma (DLBCL). In Brazil, despite its importance and frequency there are very few epidemiological data concerning lymphomas, specially the extranodal ones. In order to study the primary gastric lymphoma features in a Brazilian population, 60 patients were retrospectively evaluated. Thirty eight cases (63.3%) were classified as DLBCL and 22 (36.6%) as MALT lymphoma. There were no significant differences between the 2 groups in terms of sex, age, gastric symptoms, B symptoms, Bulky disease, bone marrow infiltration, stage, H. pylori infection, laboratory and endoscopic findings. Different treatment methods were adopted. The complete remission rate was 73.1% for DLBCL and 95% for MALT lymphoma. The disease free survival in 7 years was 84.8 for DLBCL and 94.1% for MALT lymphoma. The 7 year overall survival (OS) rate for DLBCL was 65.7% and 5 year OS for MALT was 92.9%. Because we could not demonstrate differences between the two histological groups, we conclude that the correct histological diagnosis is essential for choosing the best therapeutic approach.
