The use of patient-orientated questionnaires is of utmost importance in assessing the outcome of spine surgery. Standardisation, using a common set of outcome measures, is essential to aid comparisons across studies/in registries. The Core Outcome Measures Index (COMI) is a short, multidimensional outcome instrument validated for patients with spinal disorders. This study aimed to produce a Brazilian-Portuguese version of the COMI. A cross-cultural adaptation of the COMI into Brazilian-Portuguese was carried out using established guidelines. 104 outpatients with chronic LBP (> 3 months) were recruited from a Public Health Spine Medical Care Centre. They completed a questionnaire booklet containing the newly translated COMI, and other validated symptom-specific questionnaires: Oswestry Disability Index (ODI) and Roland Morris disability scale (RM), and a pain visual analogue scale. All patients completed a second questionnaire within 7-10 days to assess reproducibility. The COMI summary score displayed minimal floor and ceiling effects. On re-test, the responses for each individual domain of the COMI were within 1 category in 98% patients for the domain 'function', 96% for 'symptom-specific well-being', 97% for 'general quality of life', 99% for 'social disability' and 100% for 'work disability'. The intraclass correlation coefficients (ICC2,1) for COMI pain and COMI summary scores were 0.91-0.96, which compared favourably with the corresponding values for the RM (ICC, 0.99) and ODI (ICC, 0.98). The standard error of measurement for the COMI was 0.6, giving a "minimum detectable change" (MDC95%) of approximately 1.7 points i.e., the minimum change to be considered "real change" beyond measurement error. The COMI scores correlated as hypothesised (Rho, 0.4-0.8) with the other symptom-specific questionnaires. The reproducibility of the Brazilian-Portuguese version of the COMI was comparable to that of other language versions. The COMI scores correlated in the expected manner with existing but longer symptom-specific questionnaires suggesting good convergent validity for the COMI. The Brazilian-Portuguese COMI represents a valuable tool for Brazilian study-centres in future multicentre clinical studies and surgical registries.

OBJECTIVE: Anticoagulation is a challenge for the prophylaxis of thromboembolic events in elderly patients with chronic atrial fibrillation. Stable anticoagulation is defined as the time within > 70% of the therapeutic range. However, the dosage required to achieve stable anticoagulation remains unknown. The aim of this study was to analyze the warfarin dose necessary for the maintenance of stable oral anticoagulation therapy in elderly patients. METHODS: We analyzed 112 consecutive outpatients with atrial fibrillation who were >= 65 years of age, had received anticoagulation therapy with warfarin for more than 1 year and had a stable international normalized ratio between 2.0 and 3.0 for >= 6 months. The international normalized ratio was measured in the central laboratory using the traditional method. RESULTS: The patients were stratified according to the following age groups:,75 or >= 75 years and <80 or >= 80 years. The mean daily doses of warfarin were similar for patients, <75 or >= 75 years (3.34 +/- 1.71 versus 3.26 +/- 1.27 mg/day, p = 0.794) and <80 or >= 80 years (3.36 +/- 1.49 versus 3.15 +/- 1.23 mg/day, p = 0.433). In 88 (79%) patients, the daily warfarin dose was between 2 and 5 mg/day; in 13 (11%) patients, the daily warfarin dose was,2.0 mg/day; and in 11 (10%) patients, the daily warfarin dose was >5.0 mg/day. The correlation between the daily warfarin dose and the international normalized ratio was 0.22 (p = 0.012). CONCLUSION: Stable anticoagulation was achieved in 80% of patients who received doses of 2 to 5 mg/day of warfarin, and the mean daily dose was similar across the age groups analyzed.

This study's purpose was to identify the therapeutic journey of families seeking health care for their children with respiratory diseases. This qualitative study had the participation of parents of children younger than five years old who were hospitalized with respiratory diseases. Path mapping was used as an instrument to collect data, which was analyzed through thematic analysis. The finding indicate that families sought the health services as soon as they perceived symptoms and had access to medical care, however such care was not decisive in resolving their health issues. Even though the families returned to the service at least another three times, the children had to be hospitalized. The attributes of primary health care were not observed in the public health services, while therapeutic encounters had no practical success.

Extracorporeal treatments (ECTRs), such as hemodialysis and hemoperfusion, are used in poisoning despite a lack of controlled human trials demonstrating efficacy. To provide uniform recommendations, the EXTRIP group was formed as an international collaboration among recognized experts from nephrology, clinical toxicology, critical care, or pharmacology and supported by over 30 professional societies. For every poison, the clinical benefit of ECTR is weighed against associated complications, alternative therapies, and costs. Rigorous methodology, using the AGREE instrument, was developed and ratified. Methods rely on evidence appraisal and, in the absence of robust studies, on a thorough and transparent process of consensus statements. Twenty-four poisons were chosen according to their frequency, available evidence, and relevance. A systematic literature search was performed in order to retrieve all original publications regardless of language. Data were extracted on a standardized instrument. Quality of the evidence was assessed by GRADE as: High = A, Moderate = B, Low = C, Very Low = D. For every poison, dialyzability was assessed and clinical effect of ECTR summarized. All pertinent documents were submitted to the workgroup with a list of statements for vote (general statement, indications, timing, ECTR choice). A modified Delphi method with two voting rounds was used, between which deliberation was required. Each statement was voted on a Likert scale (1-9) to establish the strength of recommendation. This approach will permit the production of the first important practice guidelines on this topic.

Case fatality rate is considered a main determinant of stroke mortality trends. We applied the World Health Organization's Stroke STEPS to identify case fatality rates in a community hospital in Brazil. We evaluated all patients with first-ever stroke seeking acute care at the hospital's emergency ward between April 2006 and December 2008 to verify early and late case fatality according to stroke subtype. We used years of formal education as a surrogate for socioeconomic status. Of 430 first-ever stroke events, 365 (84.9%) were ischemic and 65 (15.1%) were intracerebral hemorrhage. After 1 year, we adjudicated 108 deaths (86 ischemic; 22 hemorrhagic). Age-adjusted case fatality rates for ischemic stroke and intracerebral hemorrhage were 6.0% v 19.8% at 10 days, 10.6% v 22.1% at 28 days, 17.6% v 29.1% at 6 months, and 21.0% v 31.5% at 1 year. Illiteracy or no formal education was a predictor of death at 6 months (odds ratio [OR], 4.31; 95% confidence interval [CI] 1.34-13.91) and 1 year (OR, 4.21; 95% CI, 1.45-12.28) in patients with ischemic stroke, as well as at 6 months (OR, 3.19; 95% CI, 1.17-8.70) and 1 year (OR, 3.30; 95% CI, 1.30-8.45) for all stroke patients. Other variables, including previous cardiovascular risk factors and acute medical care, did not change this association to a statistically significant degree. In conclusion, case fatality, particularly up to 6 months, was higher in hemorrhagic stroke, and lack of formal education was associated with increased stroke mortality.

Objective: To assess the waiting time for eye care identifying the number of patients with each complaint; to investigate how the waiting time may worsen the patient's condition; to check the screening of urgent cases for effectiveness; and to devise means of increasing the medical-surgical care capacity. Methods: A retrospective descriptive survey was conducted using data obtained on 12 occasions during collaborative team visits to provide eyecare services. These initiatives were designed to decrease the waiting time and to treat urgent cases that occurred on each occasion; eyecare services were provided every Saturday, in the period from June to August 2006, in 16 cities of the region covered by Conderg (Consortium for the Development of the Sao Joao da Boa Vista Administrative Region). Results: Referrals used 1,743 (87.1%) of the 2,000 places available. The most frequent diagnoses were refractive errors, with 683 cases, corresponding to 39.1% of the total, followed by cataracts, with 296 cases, corresponding to 20.9%. Of the 238 surgeries indicated, 54.6% were phakectomies. Thirty-five (2.0%) cases were considered urgent. Conclusion: The most common diagnoses made during the team visits to manage the excess demand for eyecare were refractive errors and cataracts, which, together, accounted for the majority of the cases. The Divinolandia Hospital has the necessary human and material resources to meet the demand left unattended by the local SUS network. Immediate referral of urgent cases by the primary units' screeners proved effective.

Bannayan-Riley-Ruvalcaba syndrome (BRRS) is a rare autosomal, dominantly-inherited, hamartoma syndrome with distinct phenotypic features. Mutations in the PTEN gene have been identified in PTEN hamartoma tumor syndromes. Our aim was to determine the correlation of phenotype-genotype relationships in a BRRS case. We have evaluated a PTEN mutation in a patient with vascular anomalies and the phenotypic findings of BRRS. We described an 8-year-old girl with the clinical features of BRRS, specifically with vascular anomalies. The mutation in the PTEN gene was identified by DNA sequencing. In our patient, we defined a de novo nonsense R335X (c. 1003 C>T) mutation in exon 8, which results in a premature termination codon. Due to vascular anomalies and hemangioma, the patient's left leg was amputated 1 year after the hemangioma diagnosis. Bannayan - Riley - Ruvalcaba syndrome patients with macrocephaly and vascular anomalies should be considered for PTEN mutation analysis and special medical care.

Obstructive sleep apnoea/hypopnoea syndrome (OSAHS) is the periodic reduction or cessation of airflow during sleep. The syndrome is associated whit loud snoring, disrupted sleep and observed apnoeas. Surgery aims to alleviate symptoms of daytime sleepiness, improve quality of life and reduce the signs of sleep apnoea recordered by polysomnography. Surgical intervention for snoring and OSAHS includes several procedures, each designed to increase the patency of the upper airway. Procedures addressing nasal obstruction include septoplasty, turbinectomy, and radiofrequency ablation (RF) of the turbinates. Surgical procedures to reduce soft palate redundancy include uvulopalatopharyngoplasty with or without tonsillectomy, uvulopalatal flap, laser-assisted uvulopalatoplasty, and RF of the soft palate. More significant, however, particularly in cases of severe OSA, is hypopharyngeal or retrolingual obstruction related to an enlarged tongue, or more commonly due to maxillomandibular deficiency. Surgeries in these cases are aimed at reducing the bulk of the tongue base or providing more space for the tongue in the oropharynx so as to limit posterior collapse during sleep. These procedures include tongue-base suspension, genioglossal advancement, hyoid suspension, lingualplasty, and maxillomandibular advancement. We reviewed 269 patients undergoing to osas surgery at the ENT Department of Forlì Hospital in the last decade. Surgery was considered a success if the postoperative apnea/hypopnea index (AHI) was less than 20/h. According to the results, we have developed surgical decisional algorithms with the aims to optimize the success of these procedures by identifying proper candidates for surgery and the most appropriate surgical techniques. Although not without risks and not as predictable as positive airway pressure therapy, surgery remains an important treatment option for patients with obstructive sleep apnea (OSA), particularly for those who have failed or cannot tolerate positive airway pressure therapy. Successful surgery depends on proper patient selection, proper procedure selection, and experience of the surgeon. The intended purpose of medical algorithms is to improve and standardize decisions made in the delivery of medical care, assist in standardizing selection and application of treatment regimens, to reduce potential introduction of errors. Nasal Continuous Positive Airway Pressure (nCPAP) is the recommended therapy for patients with moderate to severe OSAS. Unfortunately this treatment is not accepted by some patient, appears to be poorly tolerated in a not neglible number of subjects, and the compliance may be critical, especially in the long term if correctly evaluated with interview as well with CPAP smart cards analysis. Among the alternative options in Literature, surgery is a long time honoured solution. However until now no clear scientific evidence exists that surgery can be considered a really effective option in OSAHS management. We have design a randomized prospective study comparing MMA and a ventilatory device (Autotitrating Positive Airways Pressure – APAP) in order to understand the real effectiveness of surgery in the management of moderate to severe OSAS. Fifty consecutive previously full informed patients suffering from severe OSAHS were enrolled and randomised into a conservative (APAP) or surgical (MMA) arm. Demographic, biometric, PSG and ESS profiles of the two group were statistically not significantly different. One year after surgery or continuous APAP treatment both groups showed a remarkable improvement of mean AHI and ESS; the degree of improvement was not statistically different. Provided the relatively small sample of studied subjects and the relatively short time of follow up, MMA proved to be in our adult and severe OSAHS patients group a valuable alternative therapeutical tool with a success rate not inferior to APAP.

La bioetica è il luogo ideale per cercare risposte ai grandi interrogativi concernenti la vita, la morte e la cura dell'essere umano. I recenti dibattiti sull'uso, ed il temuto abuso, del corpo umano in medicina hanno messo in evidenza la necessità di una discussione approfondita sul potere di scelta che l'individuo può esercitare sulla propria mente e sul proprio corpo. Spinta dal desidero di indagare l'estensione di tale potere di scelta ho voluto analizzare le tematiche riguardanti “il corpo”, “l'individuo”, “la proprietà” e “l'autodeterminazione”. L'analisi è stata condotta individuando alcuni dei differenti significati che questi termini assumono nei diversi ambiti che la bioetica lambisce e mostrando, in particolare, la visione di tale realtà attraverso le lenti del giurista. A chi appartiene il corpo? Chi ha il potere di decidere su di esso? Il potere di scelta valica gli antichi i confini legati al corpo del paziente e coinvolge tessuti, organi e cellule staccati dal corpo umano, parti che un tempo erano considerati scarti operatori sono oggi divenuti tesori inestimabili per la ricerca. L'importanza assunta dai campioni biologici ha portato alla creazione di biobanche nelle quali sono raccolti, catalogati e il DNA studiato in campioni biologici Le biobanche riflettono le tensioni della bioetica e del biodititto. Lo studio delle biobanche riguarda, tra l'altro, la riceca dell'equilibrio tra le diverse esigenze meritevoli di tutela: in primo luogo il diritto alla privacy, diritto a che le “proprie informazioni” non vengano divulgate ed il diritto a non essere discriminato ed in secondo luogo le necessità dettate dalla ricerca e dalla scienza medica. Nel 2009 la rivista Times messo biobanche tra le 10 idee in grado di cambiare il mondo anche in considarazione della medicina personalizzata e del fatto che costituiscono una la speranza per la ricerca contro le malattie attuali e future.

Im Zentrum der vorliegenden Untersuchung steht die Nutzung von Medizinalpflanzen vor dem Hintergrund einer zurückgehenden Phytodiversität in Nordbenin. Die Dissertation ba-siert auf ethnologischen Forschungen, die in das interdisziplinäre Forschungsprojekt BIOTA (Biodiversity Monitoring Transect Analysis in Africa) eingebunden sind. Das BIOTA-Projekt untersucht die Wirkung menschlichen Handelns (insbesondere Nutzung) auf die Biodiversi-tät und versucht aus diesen Erkenntnissen Maßnahmen zum Erhalt der biologischen Vielfalt abzuleiten. Die vorliegende Studie basiert auf einem 13-monatigen Feldforschungsaufenthalt im Zeitraum von April 2004 bis August 2006 in der nordbeninischen Gemeinde Ouassa-Pehunco. Meine Informanten sind überwiegend traditionelle Heiler, mit denen ich standardi-sierte und offene Interviews durchführte, deren Behandlungsverfahren und Heilzeremonien ich teilnehmend beobachtete sowie dokumentierte und auf deren Initiative hin ich mich bei dem Aufbau eines Medizinalpflanzengartens einbrachte (cf. Kap. 1). In diesem Forschungsfeld situiere ich mich mit der Frage nach dem Einfluss einer verän-derten Pflanzenvielfalt auf die traditionelle medizinische Versorgung der Baatombu Nordbe-nins. Die Beantwortung dieser Frage erfolgt in mehreren Schritten. 1. Die Phytodiversität nimmt, wie von naturwissenschaftlicher Seite bestätigt, in der Region ab. 2. Lokale Heilkun-dige nehmen diesen Rückgang an verfügbaren Heilpflanzen ebenso wahr. 3. Die Abnahme der Pflanzenbestände führen die Heiler vor allem auf den Baumwollanbau und die demogra-fischen Entwicklungen der Region zurück - dies entspricht ebenfalls den Auffassungen von Naturwissenschaftlern, die eine Verdichtung der landwirtschaftlichen Bodennutzung fest-stellten. 4. Heilkundige und Heilpflanzenverkäuferinnen vermerken eine zunehmende Nach-frage nach lokaler Pflanzenmedizin aufgrund der steigenden Bevölkerungszahlen. 5. Die pflanzenbasierte Gesundheitsversorgung der lokalen Bevölkerung ist jedoch relativ gesi-chert, da die Heiler sich alternativ wirkender Medizinalpflanzen bedienen, ihre Therapiefor-men der veränderten Lage anpassen (z.B. geringere Dosierungen) und sie regelmäßig genutz-te Pflanzen im Medizinalpflanzengarten Guson wieder anpflanzen. Ein wichtiger Aspekt der Arbeit ist, dass die Heilpraktiken der Baatombu nicht allein auf naturheilkundlichem Erfahrungswissen beruhen, sondern in magisch-religiöse Vorstellungen eingebettet sind (cf. Kap. 2). Demzufolge untersuche ich die lokalen Krankheits- und Ge-sundheitsvorstellungen und die symbolischen Klassifikationen von Heilpflanzen und Krank-heiten (cf. Kap. 3). Ich stellte fest, dass nach Auffassung von Heilkundigen soziokulturelle Faktoren wie der Zeitpunkt und der Ort einer Sammlung sowie entsprechende Ernte-Rituale die medizinische Wirksamkeit von Pflanzen maßgeblich bedingen (cf. Kap. 5). Die Umwelt-klassifikation der Heiler (Landschafts- und Vegetationstypen) richtet sich demzufolge nach dem medizinischen Wert, den sie einer Heilpflanze zuschreiben (cf. Kap.4). Basierend auf diesen Erkenntnissen wurde von einigen engagierten Heilern und mit Un-terstützung von BIOTA, der GTZ und der Deutschen Botschaft der Medizinalpflanzengarten Guson eingerichtet, der eine Antwort auf die regionale Ressourcenverknappung darstellt und in seiner Anlage dem lokalen ökologischen und heilkundlichen Wissen der Heiler entspricht (cf. Kap. 6). Den Anwendungsbezug der Forschung nutzten die Heiler, um sich als Interes-sensgemeinschaft für den Erhalt der benötigten pflanzlichen Ressourcen einzusetzen.

L’obiettivo di questa tesi è rilevare se e quanto i medical dramas abbiano contribuito a ridefinire conoscenze, aspettative e pratiche dei telespettatori/pazienti rispetto a questioni concernenti la salute e il loro ruolo all’interno della relazione medico-paziente. Grazie ad un lavoro di campo, fatto di questionari e interviste con utenti, operatori della sanità di Centro e Nord Italia e studenti di Medicina, sono state poi registrate le modalità di interazione che i protagonisti della scena della cura dichiarano di sperimentare quotidianamente. Ciò ha permesso di rendere conto delle trasformazioni più recenti della professione medica e di come viene elaborato oggi il sapere sulla malattia da parte dei soggetti implicati, fra tecnicismi, atteggiamenti difensivi, sfiducia e affidamento. La tesi restituisce anche alcune modalità sperimentali di interazione fra pazienti e medici, messe in atto in contesti locali, che testimoniano l’esigenza di approdare a un sapere partecipato delle relazioni di cura. Infine, raccogliendo la sfida posta dalle medical humanities, immagina un utilizzo del medical drama nella formazione degli studenti di medicina per l’apprendimento di competenze narrative necessarie ad una pratica medica più umana e efficace.

Low back pain (LBP) is the most prevalent health problem in Switzerland and a leading cause of reduced work performance and disability. This study estimated the total cost of LBP in Switzerland in 2005 from a societal perspective using a bottom-up prevalence-based cost-of-illness approach. The study considers more cost categories than are typically investigated and includes the costs associated with a multitude of LBP sufferers who are not under medical care. The findings are based on a questionnaire completed by a sample of 2,507 German-speaking respondents, of whom 1,253 suffered from LBP in the last 4 weeks; 346 of them were receiving medical treatment for their LBP. Direct costs of LBP were estimated at 2.6 billion and direct medical costs at 6.1% of the total healthcare expenditure in Switzerland. Productivity losses were estimated at 4.1 billion with the human capital approach and 2.2 billion with the friction cost approach. Presenteeism was the single most prominent cost category. The total economic burden of LBP to Swiss society was between 1.6 and 2.3% of GDP.

This study seeks to answer whether the availability heuristic leads physicians to utilize more medical care than is economically efficient. Do rare, salient events alter physicians' perceptions about the probability of patient harm? Do these events lead physicians to overutilize certain medical procedures? This study uses Pennsylvania inpatient hospital admissions data from 2009 aggregated at the physician level to investigate these questions. The data come from the 2009 Pennsylvania Health Care Cost Containment Council (PHC4). The study is divided into two parts. In Part I, we examine whether bad outcomes during childbirth (defined as maternal mortality, an obstetric fistula or a uterine rupture) lead physicians to utilize more cesarean sections on future patients. In Part II, we examine whether bad outcomes associated with appendicitis (defined as patient death, a perforated or ruptured appendix or sepsis) lead physicians to perform more negative appendectomies (appendectomies performed when the patient did not have appendicitis) on future patients. Overall the study does not find evidence to support the claim that the availability heuristic leads physicians to overutilize medical care on future patients. However, the study does find evidence that variations in health care utilization are strongly correlated with individual physician practice patterns. The results of the study also imply that physicians' financial incentives may be a source of variation in health care utilization.
