Doctors must regularly adjust their patients' care according to recent relevant publications. The chief residents from the Department of Internal Medicine of a university hospital present some major themes of internal medicine treated during the year 2008, such as heart failure, diabetes, COPD, and thromboembolic disease. Emphasis will be placed primarily on changes in the daily hospital practice induced by these recent studies. This variety of topics illustrates both the broad spectrum of the current internal medicine, and the many uncertainties associated with modem medical practice based on evidence.

Research carried out in several Anglo-Saxon countries shows that many undergraduatesidentify oral sex and anal sex as examples of abstinent behaviour, while manyothers consider kissing and masturbation as examples of having sex. The objective ofthis research was to investigate whether a sample of Spanish students gave similarreplies. Seven hundred and fifty undergraduates (92% aged under 26, 67.6%women) produced examples or definitions of the term ‘abstinence’. Spanish studentsmade similar errors to those observed in the Anglo-Saxon samples, in thatbehaviours that were abstinent from a preventive point of view (masturbating andsex without penetration) were not considered as such, while a number of studentsreported oral sex as abstinent behaviour. The results suggest that the information onrisky and preventive sexual behaviour should cease to use ambiguous or euphemisticexpressions and use vocabulary that is clear and comprehensible to everyone

OBJECTIVE To describe what is, to our knowledge, the first nosocomial outbreak of infection with pan-drug-resistant (including colistin-resistant) Acinetobacter baumannii, to determine the risk factors associated with these types of infections, and to determine their clinical impact. DESIGN Nested case-control cohort study and a clinical-microbiological study. SETTING A 1,521-bed tertiary care university hospital in Seville, Spain. PATIENTS Case patients were inpatients who had a pan-drug-resistant A. baumannii isolate recovered from a clinical or surveillance sample obtained at least 48 hours after admission to an intensive care unit (ICU) during the time of the epidemic outbreak. Control patients were patients who were admitted to any of the "boxes" (ie, rooms that partition off a distinct area for a patient's bed and the equipment needed to care for the patient) of an ICU for at least 48 hours during the time of the epidemic outbreak. RESULTS All the clinical isolates had similar antibiotic susceptibility patterns (ie, they were resistant to all the antibiotics tested, including colistin), and, on the basis of repetitive extragenic palindromic-polymerase chain reaction, it was determined that all of them were of the same clone. The previous use of quinolones and glycopeptides and an ICU stay were associated with the acquisition of infection or colonization with pan-drug-resistant A. baumannii. To control this outbreak, we implemented the following multicomponent intervention program: the performance of environmental decontamination of the ICUs involved, an environmental survey, a revision of cleaning protocols, active surveillance for colonization with pan-drug-resistant A. baumannii, educational programs for the staff, and the display of posters that illustrate contact isolation measures and antimicrobial use recommendations. CONCLUSIONS We were not able to identify the common source for these cases of infection, but the adopted measures have proven to be effective at controlling the outbreak.

Syphilis is a chronic infection that is categorized by a three-stage progression. The tertiary stage may affect bones and produce distinctive skull lesions called caries sicca. This paper aims to present an unusual case of syphilis associated with a diagnosis of cirrhosis, which was recorded as the cause of death in a 28-year-old female in 1899. The appearance and distribution of the lesions were compatible with acquired syphilis, as observed in the skull from the Medical Schools Collection of the University of Coimbra. However, the cause of death was recorded as "hypertrophic cirrhosis of the liver", this is a condition that is compatible with several liver disorders, including a primary liver disorder, such as cirrhosis provoked by alcoholism, infection of the liver by syphilis pathogens or by damage to the liver from the use of mercury compounds, which was the common treatment for syphilis at the time. This paper represents a contribution to the understanding of the natural evolution of syphilis.

Virulence and antibiotic resistance are significant determinants of the types of infections caused by Staphylococcus aureus and paediatric groups remain among the most commonly affected populations. The goal of this study was to characterise virulence genes of methicillin-susceptible S. aureus (MSSA) and methicillin-resistant S. aureus (MRSA) strains isolated from a paediatric population of a Colombian University Hospital during 2009. Sixty MSSA and MRSA isolates were obtained from paediatric patients between zero-14 years. We identified the genes encoding virulence factors, which included Panton-Valentine leucocidine (PVL), staphylococcal enterotoxins A-E, exfoliative toxins A and B and toxic shock syndrome toxin 1. Typing of the staphylococcal chromosome cassette mec (SCCmec) was performed in MRSA strains. The virulence genes were more diverse and frequent in MSSA than in MRSA isolates (83% vs. 73%). MRSA strains harboured SCCmec types IVc (60%), I (30%), IVa (7%) and V (3%). SCCmec type IVc isolates frequently carried the PVL encoding genes and harboured virulence determinants resembling susceptible strains while SCCmec type I isolates were often negative. PVL was not exclusive to skin and soft tissue infections. As previously suggested, these differences in the distribution of virulence factor genes may be due to the fitness cost associated with methicillin resistance.

BACKGROUND: Anaemia represents a common complication of inflammatory bowel disease (IBD). Most studies on anaemia in IBD patients have been performed in tertiary referral centres (RC) and data from gastroenterologic practices (GP) are lacking. We investigated the frequency and severity of anaemia in IBD patients from tertiary referral centres and gastroenterologic practices compared to the general population. METHODS: Data were acquired from patients included in the Swiss IBD Cohort Study. IBD activity was evaluated by CDAI and modified Truelove and Witts severity index (MTWSI). Anaemia was defined as haemoglobin ≤120g/L in women and ≤130g/L in men. RESULTS: 125 patients from RC (66 with Crohn's disease (CD) and 59 with ulcerative colitis (UC)) and 116 patients from GP (71 CD and 45 UC) were included and compared to 6074 blood donors. Anaemia was found in 21.2% (51/241) of the IBD patients and more frequently in patients from RC as compared to GP and healthy controls (28.8% vs. 12.9% vs. 3.4%; P<0.01). IBD patients from RC suffered more frequently from active disease compared to IBD patients in GP (36% vs. 23%, P=0.032). Supplementation therapy (iron, vitamin B12, folic acid) was performed in 40% of anaemic IBD patients in GP as compared to 43% in RC. CONCLUSIONS: Anaemia is a common complication in patients with IBD and significantly more prevalent in patients from referral centres as compared to patients from gastroenterologic practices. Physicians treating IBD patients should pay attention to the presence of anaemia and ensure sufficient supplementation therapy.

RÉSUMÉ Il existe dans la pratique de prescription des médicaments de grandes variations entre les hôpitaux. Ces variations sont d'origines multifactorielles, comme par exemple des traditions de prescriptions locales, des considérations pharmato-économiques, la disponibilité d'un médicament, des différences de population, la prévalence d'une maladie, etc. Les études disponibles sur les pratiques de prescription sont souvent réduites à un centre unique, à une région ou à un pays. L'emploi de méthodes et de définitions particulières a jusqu'à pressent limité des comparaisons plus étendues entre les pays et régions. Le but de cette étude est de comparer la pratique de prescription de nouveaux médicaments psychotropes dans des cliniques suisses et allemandes. Cinq hôpitaux psychiatriques ont été sélectionnés, faisant tous partie du projet AMSP, et représentant des cliniques suisses, allemandes, de niveau universitaire ou non. Des données sur 572 patients et 1745 prescriptions ont été collectées durant un jour précis. Les comparaisons ont été ajustées pour l'âge et le sexe. Une différence significative (p <0.001) a été trouvée dans la prescription de nouveaux médicaments antidépresseurs, les cliniciens suisses en donnant en moyenne plus (65.2%) que les allemands (48.3%). Aucune différence significative n'a été démontrée dans la prescription des nouveaux médicaments antipsychotiques atypiques. Il semble en conséquence que les psychiatres suisses ont une propension plus élevée à prescrire des nouveaux médicaments antidépresseurs. Cela semble être dû à des différences de traditions de prescriptions nationales ou régionales. D'autres études sont nécessaires pour investiguer les influences économiques sur la pratique de prescription dans des cliniques suisses et allemandes. SUMMARY Obiective: There are great variations between hospitals in the way drugs are prescribed and these variations may be due to multiple factors such as local prescribing traditions, pharmacoeconomic considerations, drug availability; regional differences of population, disease prevalence etc. Available studies on prescribing habits have, besides studies performed in a unique centre, until now often been restricted to single countries or regions and the comparisons across countries or regions have often been limited by the use of diverse methodologies and definitions. The aim of the present study was to compare drug prescriptions between German and Swiss psychiatric services with regard to their preference of newer psychotropics. Material, method: Five psychiatric hospitals, associated to the AMSP-project, were chosen to represent Swiss and German clinics, university and non-university settings. Data were available from one index day on 572 patients and 1745 prescriptions. The comparisons were adjusted for age and gender. Results: There was a significant difference (p < 0.001) with regard to the prescription of newer antidepressants (NAD), Swiss clinicians giving proportionally more (65.2 %) than the German psychiatrists (48.3 %). No significant difference was, on the other hand, found as to the proportion of atypical antipsychotics, the lack of difference being due to the higher proportion of clozapine among the atypical antipsychotics in Germany. Conclusion: There seems therefore to be a higher propensity for Swiss hospital psychiatrists to prescribe newer antidepressants. This seems to be due to national or regional prescribing traditions. Further studies are needed to investigate the economical influences on antidepressant prescribing in Swiss and German clinics.)
