Outpatient thyroidectomy is safe and reasonable: experience with more than 1,000 planned outpatient procedures.

Background: Thyroidectomy has traditionally been performed as an inpatient hospital procedure, but low risk and high patient tolerance make it acceptable as an outpatient procedure.

Study Design: All thyroidectomies performed by a single surgeon between March 2003 and June 2009 were retrospectively and prospectively reviewed as planned outpatient or planned inpatient operations, noting the patient's American Society of Anesthesiologists (ASA) classification, success of completion as an outpatient procedure, time to same-day discharge, postoperative emergency room visit, hospital admission, and complications.

Results: Overall, 1,136 of 1,242 thyroidectomies were planned as outpatient procedures and 1,063 (93.

Aromatic residues at the edge of the antibody combining site facilitate viral glycoprotein recognition through membrane interactions.

The broadly neutralizing anti-HIV antibody 4E10 recognizes an epitope very close to the virus membrane on the glycoprotein gp41. It was previously shown that epitope recognition improves in a membrane context and that 4E10 binds directly, albeit weakly, to lipids. Furthermore, a crystal structure of Fab 4E10 complexed to an epitope peptide revealed that the centrally placed, protruding H3 loop of the antibody heavy chain does not form peptide contacts.

Hyperhomocysteinemia selectively alters expression and stoichiometry of intermediate filament and induces glutamate- and calcium-mediated mechanisms in rat brain during development.

The aim of the present work was to investigate the actions of a chemically induced chronic hyperhomocysteinemia model on intermediate filaments (IFs) of cortical and hippocampal neural cells and explore signaling mechanisms underlying such effects. Results showed that in hyperhomocysteinemic rats the expression of neural IF subunits was affected. In cerebral cortex, glial fibrillary acidic protein (GFAP) expression was donwregulated while in hippocampus high and middle molecular weight neurofilament subunits (NF-H and NF-M, respectively) were up-regulated.

Methylphenidate treatment increases Na(+), K (+)-ATPase activity in the cerebrum of young and adult rats.

Methylphenidate is a central nervous system stimulant used for the treatment of attention-deficit hyperactivity disorder. Na(+), K(+)-ATPase is a membrane-bound enzyme necessary to maintain neuronal excitability. Considering that methylphenidate effects on central nervous system metabolism are poorly known and that Na(+), K(+)-ATPase is essential to normal brain function, the purpose of this study was to evaluate the effect of this drug on Na(+), K(+)-ATPase activity in the cerebrum of young and adult rats.

[Recurrent abcesses of the parotid gland in Sjögren's syndrome].

We report on a 48-year old female patient suffering from recurrent suppurative sialo-adenitis. Resections of both parotid and the left submandibular glands had to be performed due to abscesses. The woman had suffered from recurrent swelling of the salivary glands as well as xerostomia and xerophthalmia for years.

[Complication after subacute cervical lymphadenitis].

A 56-year-old female patient presented with a 3-day-old odynophagy and a painful swelling in the left side of the neck. In addition to reddening and swelling of the left side of the neck, which was painful on palpation, leukocytosis and increased C-reactive protein (CRP) and fibrinogen levels were also found. Enlarged lymph nodes along the left vessel-nerve sheath and thrombosis of the internal jugular vein were detected by sonography and computed tomography.

(142)Nd evidence for an enriched Hadean reservoir in cratonic roots.

The isotope (146)Sm undergoes alpha-decay to (142)Nd, with a half-life of 103 million years. Measurable variations in the (142)Nd/(144)Nd values of rocks resulting from Sm-Nd fractionation could therefore only have been produced within about 400 million years of the Solar System's formation (that is, when (146)Sm was extant). The (142)Nd/(144)Nd compositions of terrestrial rocks are accordingly a sensitive monitor of the main silicate differentiation events that took place in the early Earth.

Na+,K+-ATPase activity in an animal model of mania.

We evaluated Na(+),K(+)-ATPase activity in hippocampus of rats submitted to an animal model of mania which included the use of lithium and valproate. In the acute treatment, amphetamine or saline was administered to rats for 14 days, between day 8 and 14, rats were treated with lithium, valproate or saline. In the maintenance treatment, rats were treated with lithium, valproate or saline, between day 8 and 14, amphetamine or saline were administered.

Chronic hyperhomocysteinemia alters antioxidant defenses and increases DNA damage in brain and blood of rats: protective effect of folic acid.

We have previously demonstrated that acute hyperhomocysteinemia induces oxidative stress in rat brain. In the present study, we initially investigated the effect of chronic hyperhomocysteinemia on some parameters of oxidative damage, namely total radical-trapping antioxidant potential and activities of antioxidant enzymes (superoxide dismutase, catalase and glutathione peroxidase), as well as on DNA damage in parietal cortex and blood of rats. We also evaluated the effect of folic acid on biochemical alterations elicited by hyperhomocysteinemia.

25 years of HIV research on virology, virus restriction, immunopathogenesis, genes and vaccines.

From 19 to 21 May 2008 an important meeting was held at the Pasteur Institute in Paris to mark the 25th Anniversary of the discovery of HIV as the aetiological agent of AIDS. This review summarizes the historical findings, recent work and future directions presented at this meeting.

Formation of alpha-dicarbonyl compounds in beer during storage of Pilsner.

With the aim of determining the formation of alpha-dicarbonyl intermediates during beer aging on the shelf, alpha-dicarbonyls were identified and quantified after derivatization with 1,2-diaminobenze to generate quinoxalines. The sensory effects of alpha-dicarbonyls were evaluated by the quantification of key Strecker aldehydes and by GC-olfactometry (GCO)analysis of beer headspace using solid phase microextraction. Four alpha-dicarbonyls, reported here for the first time, were detected in fresh and aged beers, three were derived from the 2,3-enolization pathway of mono- and disaccharides, and the fourth was derived from the epimerization of 3-deoxy-2-hexosulose.

Guanidinoacetate administration increases acetylcholinesterase activity in striatum of rats and impairs retention of an inhibitory avoidance task.

Guanidinoacetate methyltransferase deficiency (GAMT-deficiency) is an inborn error of metabolism biochemically characterized by accumulation of guanidinoacetate (GAA) and depletion of creatine; the pathogenesis of brain dysfunction in this disorder is not yet established. In the present study we investigated the effect of intrastriatal administration of GAA on acetylcholinesterase (AChE) activity and on memory acquisition, consolidation and retrieval of step-down inhibitory avoidance task in rat. Results showed that GAA significantly increased AChE activity in rat striatum 30 min (50%) and 3 h (25%), but not 6 h after drug administration.

Guanidinoacetate decreases antioxidant defenses and total protein sulfhydryl content in striatum of rats.

Guanidinoacetate methyltransferase (GAMT) deficiency is an inherited neurometabolic disorder biochemically characterized by tissue accumulation of guanidinoacetate (GAA) and depletion of creatine. Affected patients present epilepsy and mental retardation whose pathogeny is unclear. In the present study we investigated the in vitro and in vivo (intrastriatal administration) effects of GAA on some oxidative stress parameters in rat striatum.

Themes and time use by participants in general team meetings at a psychiatric day hospital.

This naturalistic study was realized through observation and aimed to characterize general staff meetings held at a day hospital regarding theme and the professionals' participation in the use of time. We observed 21 meetings, during which 144 announcements were made and 46 issues were discussed, with greater participation in discussions by fixed team members. In 18 of these meetings, the discussed themes corresponded to daily situations registered during the weeks preceding the meetings.

Difficulties in eliciting broadly neutralizing anti-HIV antibodies are not explained by cardiolipin autoreactivity.

Objective: In a recent report [Haynes et al. Science 2005; 308:1906-1908], difficulties in eliciting broadly neutralizing antibodies to HIV were linked to the binding of prototypic broadly neutralizing monoclonal antibodies to autoantigens and in particular, to the binding of two antigp41 antibodies, 2F5 and 4E10, to the autoantigen cardiolipin. We used a number of assays to understand whether 2F5 and 4E10 are autoreactive, polyreactive, or have a generalized affinity for lipids that may facilitate recognition of their membrane proximal epitopes.

Concurrent folate treatment prevents Na+,K+-ATPase activity inhibition and memory impairments caused by chronic hyperhomocysteinemia during rat development.

We investigated the hypothesis that folate administration would prevent hyperhomocysteinemia-induced memory deficits and Na(+),K(+)-ATPase activity inhibition. Chronic hyperhomocysteinemia was induced from the 6th to the 28th day of life by subcutaneous injection of homocysteine (0.3-0.

Reflections on the care delivered in a suspected case of infanticide.

This study resulted from the experience of supervising a suspected infanticide case hospitalized at a psychiatric ward. We aimed to find support in scientific literature about infanticide, point out an interdisciplinary health team's affliction and uncertainties when faced with this kind of case and suggest strategies for dealing with these feelings and their possible consequences in dealing with this case. Professionals involved in this case observed their discomfort about the situation and difficulties caused by feelings of guilt about the child's death, whether intentional or not.

Reduction of gangliosides, phospholipids and cholesterol content in cerebral cortex of rats caused by chronic hypermethioninemia.

Neurological dysfunction is observed in patients with severe hypermethioninemia, whose physiopathology is still poorly understood. In the current study we investigated the effect of chronic administration of methionine on the content and species of gangliosides and phospholipids, as well as on the concentration of cholesterol in rat cerebral cortex. Wistar rats received subcutaneous injections of methionine (1.

Hypermethioninemia increases cerebral acetylcholinesterase activity and impairs memory in rats.

In the present study we investigated the effect of chronic hypermethioninemia on rat performance in the Morris water maze task, as well as on acetylcholinesterase (AChE) activity in rat cerebral cortex. For chronic treatment, rats received subcutaneous injections of methionine (1.34-2.

Reflections on nursing teaching in the post-modernity era and the metaphor of a theory-practice gap.

This article presents a theoretical reflection on nursing teaching. First, we contextualize the topic regarding the globalized world and the repercussions of its paradigms on mankind and, consequently, on nursing students' learning. Next, we focus on the theory-practice gap established in the nursing learning.

Group therapy with nursing students during the theory-practice transition.

This study aimed to verify whether the intervention of short term groups could provide nursing students means to cope with stress, typical of the transition process from the theoretical to the practical learning. Participant observation was used, allowing 12 students in the discipline Fundamentals II, to express their anxieties and anguish towards the new and future role of taking care of other people's health. Results suggest that higher nursing education institutions should consider the group technique not only as a support resource, but also as a didactical resource in their curricula.

Supplementation with vitamins E plus C or soy isoflavones in ovariectomized rats: effect on the activities of Na(+), K (+)-ATPase and cholinesterases.

Since a previous study demonstrated that ovariectomized rats present an activation of Na(+), K(+)-ATPase and acetylcholinesterase (AChE) activities, in the present study we investigated the influence of vitamins E plus C or soy isoflavones on the effects elicited by ovariectomy on the activities of these enzyme in hippocampus of ovariectomized rats. We also determined the effect of the same compounds on the reduction of serum butyrylcholinesterase (BuChE) activity caused by ovariectomy. Female adult Wistar rats were assigned to one of the following groups: sham (submitted to surgery without removal of the ovaries) and ovariectomized.

Homocysteine reduces cholinesterase activity in rat and human serum.

In the present study we investigated the effect of homocysteine administration, the main metabolite accumulating in homocystinuria, on cholinesterase activity in rat and human serum. For the in vivo study, 8-, 15- and 60-day-old rats received one subcutaneous injection of homocysteine (0.3, 0.

Effect of hypermethioninemia on some parameters of oxidative stress and on Na(+),K (+)-ATPase activity in hippocampus of rats.

In the present study we investigated the effect of chronic administration of methionine, a metabolite accumulated in many inherited pathological conditions such as methionine adenosyltransferase deficiency and homocystinuria, on some parameters of oxidative stress, namely thiobarbituric acid reactive substances (TBARS), catalase activity and total thiol content, as well as on Na(+),K(+)-ATPase activity in rat hippocampus. For chronic treatment, rats received subcutaneous injections of methionine (1.34-2.
