Intravenous versus inhalation anaesthesia for one-lung ventilation

BackgroundThis is an update of a Cochrane Review first published in The Cochrane Library, Issue 2, 2008.The technique called one-lung ventilation can confine bleeding or infection to one lung, prevent rupture of a lung cyst or, more commonly, facilitate surgical exposure of the unventilated lung. During one-lung ventilation, anaesthesia is maintained either by delivering an inhalation anaesthetic to the ventilated lung or by infusing an intravenous anaesthetic. It is possible that the method chosen to maintain anaesthesia may affect patient outcomes. Inhalation anaesthetics may impair hypoxic pulmonary vasoconstriction (HPV) and increase intrapulmonary shunt and hypoxaemia.ObjectivesThe objective of this review was to evaluate the effectiveness and safety of intravenous versus inhalation anaesthesia for one-lung ventilation.Search methodsWe searched the Cochrane Central Register of Controlled Trials (CENTRAL); The Cochrane Library (2012, Issue 11); MEDLINE (1966 to November 2012); EMBASE (1980 to November 2012); Literatura Latino-Americana e do Caribe em Ciencias da Saude (LILACS, 1982 to November 2012) and ISI web of Science (1945 to November 2012), reference lists of identified trials and bibliographies of published reviews. We also contacted researchers in the field. No language restrictions were applied. The date of the most recent search was 19 November 2012. The original search was performed in June 2006.Selection criteriaWe included randomized controlled trials and quasi-randomized controlled trials of intravenous (e. g. propofol) versus inhalation (e. g. isoflurane, sevoflurane, desflurane) anaesthesia for one-lung ventilation in both surgical and intensive care participants. We excluded studies of participants who had only one lung (i.e. pneumonectomy or congenital absence of one lung).Data collection and analysisTwo review authors independently assessed trial quality and extracted data. We contacted study authors for additional information.Main resultsWe included in this updated review 20 studies that enrolled 850 participants, all of which assessed surgical participants no studies investigated one-lung ventilation performed outside the operating theatre. No evidence indicated that the drug used to maintain anaesthesia during one-lung ventilation affected participant outcomes. The methodological quality of the included studies was difficult to assess as it was reported poorly, so the predominant classification of bias was 'unclear'.Authors' conclusionsVery little evidence from randomized controlled trials suggests differences in participant outcomes with anaesthesia maintained by intravenous versus inhalational anaesthesia during one-lung ventilation. If researchers believe that the type of drug used to maintain anaesthesia during one-lung ventilation is important, they should design randomized controlled trials with appropriate participant outcomes, rather than report temporary fluctuations in physiological variables.

Rubella Vaccination of Unknowingly Pregnant Women: The Sao Paulo Experience, 2001

Background. Rubella vaccination is contraindicated during pregnancy. During mass immunization of women of childbearing age against rubella, women unknowingly pregnant may be vaccinated. To evaluate the effects of rubella vaccination during pregnancy, the Brazilian state of Sao Paulo conducted a follow-up study of pregnant women vaccinated during a rubella campaign in 2001.Methods. Women vaccinated during pregnancy were reported to a national surveillance system. In the state of Sao Paulo, follow-up of vaccinated women included household interviews. Serum samples from vaccinated women were tested for antirubella antibodies to classify susceptibility to rubella infection. Children born to susceptible mothers were tested for evidence of congenital rubella infection and evaluated for signs of congenital rubella syndrome.Results. The Sao Paulo State Health Department received 6473 notifications of women vaccinated during pregnancy. Serology performed for 5580 women identified 811 (15%) that were previously susceptible. Incidence of spontaneous abortion or stillbirth among previously susceptible vaccinated women was similar to women with prior immunity. Twenty-seven (4.7%) of 580 newborns tested had evidence of congenital rubella infection; none had congenital rubella syndrome.Conclusions. Mass rubella vaccination of women of childbearing age was not associated with adverse birth outcomes or congenital rubella syndrome among children born to women vaccinated during pregnancy.

Aspectos da toxoplasmose na clínica de pequenos animais

Toxoplasmosis, a zoonosis of worldwide distribution, has importance in human and veterinary medicine. Animals can be direct or indirect source of infection to man, and this intermediate host, the disease may be responsible for encephalitis and deaths due to congenital form as coinfection in neonates and patients with acquired immunodeficiency syndrome. The man and animals can acquire the disease by eating undercooked meat or cures, infected with tissue cysts, as well as food and water contaminated with oocysts. Iatrogenic, such as, blood transfusion and organ transplantation are other less frequent routes of transmission. The causative agent of this disease is Toxoplasma gondii, a protozoan obligate intracellular coccidian. In small animals, the infection has been reported in several countries, promoting varied clinical manifestations and uncommon but severe and fatal, which is a challenge in the clinical diagnosis of small animals, especially when the nervous system involvement. Thus, constitute the purpose of this review address the participation of small animals in the spread of the disease, clinical aspects related to it, as well as discuss methods of diagnosis, therapeutic measures, prophylaxis and control of this disease.

Meningitis and pneumococcal pyomyositis in a child with intramuscular hemangiomas: an autopsy case report

Pyomyositis is the bacterial infection of skeletal muscle, usually accompanied by abscesses. The main etiologic agent is Staphylococcus aureus. There are rare cases attributed to Streptococcus pneumoniae. This paper presents an autopsy of a four year old child with multiple congenital intramuscular hemangiomas that developed pneumococcal pyomyositis associated with meningitis. The authors propose the hypothesis that patients with hemangiomas, mainly the intramuscular type, may also represent a risk group for pyomyositis. The possibility of respiratory/meningeal co-infection, might also be considered even if the clinical picture is restricted to the muscular system.

Echocardiographic and radiographic aspects of tetralogy of Fallot in a Border Collie: case report

Tetralogy of Fallot is a complex cardiac malformation characterized by four anatomical defects: pulmonary valve stenosis, right ventricular hypertrophy, interventricular septal defect and aortic dextroposition. Imaging techniques are useful in the diagnosis of this disease, such as radiography for screening and Doppler echocardiography for a definitive diagnosis. Our objective is to report the radiographic and Doppler echocardiographic aspects of a tetralogy of Fallot case in a 10 month-old Border Collie dog.

Portal hypertension in dogs

Portal hypertension (PH) is the pathological increase in portal vein pressure above normal limits. Two variables control the pressure in the portal system: the resistance to blood flow and blood flow volume in the portal system. If one these variables changes, PH may develop. Classification: Pre-hepatic (e. g. compression of the portal vein), intrahepatic (e. g. chronic hepatitis and cirrhosis) or post-hepatic (e. g. right heart failure). The invasive methods (intravenous catheter) were replaced by an indirect method of diagnosis: Doppler Ultrasound. This technique does not measure portal pressure, but indirectly allows the diagnosis of PH. Average speed of portal flow decrease (<10 cm/s) and hepatofugal flow have been reported in cirrhotic dogs with PH. Currently, the focus of the ultrasound is the detection of acquired collateral portal circulation (ACPC), closely correlated with hepatic encephalopathy. The characterization of these vessels is essential to differentiate them from congenital shunts. They are usually multiple vessels, small and tortuous, with turbulent flow, near to the kidneys, and/or a single and larger vessel, draining into the left renal vein (dilated gonadal vein). Gastric, esophageal and mesenteric varices may occur. After identifying the PH, it is important to determine its origin in order to treat the underlying disease. B-Mode Ultrasound and Doppler are the best choices in cases of suspected PH, because they may recognize not just the hypertension, but also its complications and origin.

Correlação entre aneuploidia cromossômica em espermatozóides e taxa de implantação embrionária: subtitulo

Infertility is directly related to chromosomal abnormalities in germ cells. Among them, the aneuploidies are the most frequent chromosomal abnormalities and responsible for embryo implantation failures, miscarriages, fetal losses and newborns with congenital malformations, mental disability and neuropsychomotor developmental delay. Male patients with normal somatic karyotype may present different rates of aneuploidies in sperm, resulting in abnormal embryos. This study aimed to correlate the frequency of chromosomal aneuploidies in spermatozoa with embryo implantation rate in couples undergoing assisted reproductive techniques. The methodology has included chromosomal analysis by GTG banding and molecular cytogenetic study using Fluorescent In Situ Hybridization technique for evaluation of chromosomes 9, X and Y in germ cells of 22 patients referred to the Human Reproduction Service of the Clinical Hospital FMRP-USP. Embryo implantation rates were determined by hormonal evaluation in maternal peripheral blood and ultrasound confirmation. Two patients presented abnormal karyotype, characterized by polymorphism of the heterochromatic region of the long arm of chromosome 9 and a satellite in the short arm of chromosome 22. Both alterations, usually considered variants of normality, have been related to infertility phenotype and miscarriages. Significant differences were detected between couples who presented pregnancy (group 1) and couples with embryo implantation failure (group 2), with higher frequency of aneusomy and diploidy of chromosome 9, as well as total aneuploidy in sperm of group 2 patients. Our results suggest a correlation between aneuploidy and embryo implantation rates, since the infertile group with reproductive failure has showed higher frequency of aneuploidy. Screening for aneuploidies detection in male germ cells should be included in order to decrease embryo implantation failures, miscarriages and fetuses with chromosomal ...

Avaliação da exposição ao propionato de testosterona em ratas fêmeas in utero e lactação

It is known that exposure to substances in the environment can contribute to various reproductive disorders, especially if such exposure occurs during critical periods of development such as the intra-uterine and postnatal. The female reproductive system may be the target of androgens, both as a result of exposure to environmental chemicals, or by pathological conditions (polycystic ovary syndrome or congenital adrenal hyperplasia).Usually, little attention is given off in relation to the study of androgenic effects in the female reproductive axis. This study aims to evaluate the effects of exposure to androgens on the development, structure and reproductive function in rats whose mothers were exposed to testosterone propionate from gestational day 12 (DG12) after weaning - postnatal day 21 (DPN21) . For this purpose, pregnancy rats were divided into four groups: a control group that received corn oil (vehicle) and three groups receiving testosterone propionate in doses of 0.05 mg / kg / day, 0.1 mg / kg / day and 0.2 mg / kg / day, all under the same experimental conditions. The possible effects of exposure were assessed using reproductive parameters, such as a measure of anogenital distance, count areolas / nipples, age at vaginal opening and first estrus (puberty indicative installation), weight and histological evaluation of the reproductive organs ( uterus and ovaries), weight of the kidneys, liver and pituitary hormone levels, regularity of the estrous cycle, sexual behavior and fertility. Such analysis is important in understanding the effects of androgen exposure on the female genital system, especially on the reproductive potential, and processes that may involve morphofunctional changes. In these experimental conditions, it is concluded that treatment with PT caused reduction in body weight and initial masculinization in females without cubs, however, commit further sexual development

Atualizações sobre o uso de óleo de peixe no tratamento de cardiopatia canina

There are cardiopathies that acometem the dogs, being able this being congenital or acquired and lately have grown the number of cases due to the increase of the life expectancy of these animals becoming each time more necessary prevention methods. In recent years innumerable research is being carried through to understand the influence of the fish oil in the cardiopathies. The fish oil ingestion, Omega 3, has shown beneficial effect in the prevention of cardiovascular illnesses in such a way in the men as in the animals. Such effect this related to the presence of acid greasy polyunsaturateds n-3, mainly acid the eicosapentaenóico (EPA) and acid the docosahexaenóico (DHA). These substances can be found in foods as marine cold water fish (salmon, tuna, sardine and Trout), hemp seeds and soy. The present study, therefore, it has as objective to carry through an update on the use of the fish oil in the treatment of cardiopathies in dogs
