Dermatite atopique : données génétiques actuelles

The genetic approach has allowed identification of chromosomal loci and candidate genes involved in predisposition to atopic dermatitis. Some are skin-specific, while others are common with other atopic disorders. However, results may be discordant because of genetic heterogeneity and uncertainties about the relative importance of environmental and genetic factors in phenotype expression. The relative risk for atopic dermatitis in relatives of affected patients may be defined, and a better understanding of the pathogeny of atopic dermatitis is expected.     

Internal Medicine Residents Reject “Longer and Gentler” Training

Background Increasing complexity of medical care, coupled with limits on resident work hours, has prompted consideration of extending Internal Medicine training. It is unclear whether further hour reductions and extension of training beyond the current duration of 3 years would be accepted by trainees. Objective We aimed to determine if further work-hour reductions and extension of training would be accepted by trainees and whether resident burnout affects their opinions. Design A postal survey was sent to all 143 Internal Medicine residents at the University of Colorado School of Medicine in May 2004. Measurements The survey contained questions related to opinions on work-hour limits using a 5-point Likert scale ranging from strongly agree to strongly disagree. Burnout was measured using the Maslach Burnout Inventory, organized into three subscales: emotional exhaustion (EE), depersonalization (DP), and personal accomplishment, with burnout defined as high EE or DP. Results Seventy-four percent (106/143) of residents returned the survey. The vast majority (84%) of residents disagreed or strongly disagreed with extending training to 4 or 5 years. Burnout residents were less averse to extending training (strongly agree or agree, 18.9% vs 4.3%, P = .04). The majority of residents (68.9%) disagreed or strongly disagreed with establishing a 60-hour/week limit. Residents who met the criteria for burnout were more likely to agree that a 60-hour limit would be better than an 80-hour limit (strongly agree or agree, 22% vs 8%, P = .02). Conclusions In this program, most Internal Medicine residents are strongly opposed to extending their training to 4 or 5 years and would prefer the current 80 hours/week cap. A longer, less intense pace of Internal Medicine training seems to be less attractive in the eyes of current trainees.     

Is Training in a Primary Care Internal Medicine Residency Associated with a Career in Primary Care Medicine?

PURPOSE

Professional and governmental organizations recommend an ideal US physician workforce composed of at least 40 % primary care physicians. They also support primary care residencies to promote careers in primary care. Our study examines the relationship between graduation from a primary care or categorical internal medicine residency program and subsequent career choice.

METHODS

We conducted a cross-sectional electronic survey of a cohort of internal medicine residency alumni who graduated between 2001 and 2010 from a large academic center. Our primary predictor was graduation from a primary care versus a categorical internal medicine program and our primary outcome is current career role. We performed chi-square analysis comparing responses of primary care and categorical residents.

RESULTS

We contacted 481 out of 513 alumni, of whom 322 responded (67 %). We compared 106 responses from primary care alumni to 169 responses from categorical alumni. Fifty-four percent of primary care alumni agreed that the majority of their current clinical work is in outpatient primary care vs. 20 % of categorical alumni (p < 0.001). While 92.5 % of primary-care alumni were interested in a primary care career prior to residency, only 63 % remained interested after residency. Thirty of the 34 primary care alumni (88 %) who lost interest in a primary care career during residency agreed that their ambulatory experience during residency influenced their subsequent career choice.

CONCLUSIONS

A higher percentage of primary care alumni practice outpatient primary care as compared to categorical alumni. Some alumni lost interest in primary care during residency. The outpatient clinic experience may impact interest in primary care.

Evaluation of therapeutic strategies for myocardial infarction: the ESTIM Midi-Pyrénées survey

The aim of the ESTIM Midi-Pyrénées survey was to monitor the management of acute coronary syndrome with ST segment elevation by cardiologists and emergency departments in the Midi-Pyrénées region. Over a period of 2 years between June 2001 and June 2003, 1287 patients presenting with acute coronary syndrome within the first 24 hours were recruited prospectively. The initial management of these patients was undertaken either by a mobile medical team in the pre-hospital phase, or in a hospital emergency department, non-interventional cardiology department or an interventional cardiology department in 51.8%, 28.8%, 9.6% et 9.9% of cases respectively. Depending on these four modes of initial management, the median time for initial management was 1h30, 2h45, 4h30 et 4h respectively. Emergency coronary reperfusion was proposed in 89.6% of cases. Of the patients in whom reperfusion was attempted within the first 12 hours, 33.7% underwent pre-hospital thrombolysis (median delay of 1h48), 35.8% underwent thrombolysis in hospital (median delay 3h), and 30.4% underwent primary angioplasty (median delay 4h40). Thrombolysis was followed by angioplasty in 80% of cases. A combined approach with thrombolysis and angioplasty was applied in 41% of patients. At one month the rate of major cardiac events, death, and/or subsequent myocardial infarction was 12%. Multivariate analysis revealed that the only significant adverse prognostic features were: not offering reperfusion [Odds ratio (OR) 4, confidence interval (CI) 2.3-3.7] and age [OR 3.8, CI 2.3-6.2]. The method of reperfusion did not influence the subsequent outcome in this regional survey. Conclusion: pre-hospital management allows early revascularisation. In our region there was no significant prognostic difference between pre-hospital thrombolysis and primary angioplasty. It shows that the logistic and therapeutic potentials of prehospital care are not being sufficiently exploited.

Vaccination de l’adulte : données générales,actualités et perspectives

Vaccination in immunocompetent adult mainly concerns booster vaccination against diphtheria, tetanus, polio and pertussis. Some chronic diseases may also require the achievement of pneumococcal and influenza vaccines. In addition, from the age of 65, annual influenza vaccination as well as one dose of a live attenuated shingles vaccine between 64 and 75 years are recommended. Immunocompromised adults, due to the increased risk of serious infections responsible of significant morbidity and mortality, are particularly concerned by vaccination. Main issues in this population are the decreased immunogenicity and efficacy of vaccination and the risk of infection with live attenuated vaccines and. Depending on the type of immunosuppression, the recommended vaccines and vaccination schemes differ. Vaccination of healthy persons caring or residing with immunocompromised patients is an important point in the vaccine strategy. The current perspectives in vaccinology concern the development of vaccines against healthcare associated infections (Clostridium difficile and Staphylococcus aureus in particular), the strategy of vaccination during pregnancy to protect new-borns (respiratory syncytial virus, group B streptococcus) and the development of new adjuvants and new routes of immunization. With the overall decline in immunization coverage and increasing distrust of vaccination, the problem of vaccine hesitancy is also a hot topic. The reasons for doubt in the vaccine usefulness and the solutions to be applied are also crucial issues.     

Bartonella quintana in head lice from Sénégal

Head and body lice are strict, obligate human ectoparasites with three mitochondrial clades (A, B, and C). Body lice have been implicated as vectors of human diseases, and as the principal vectors of epidemic typhus, relapsing fever, and Bartonella quintata-associated diseases (trench fever, bacillary angiomatosis, endocarditis, chronic bacteremia, and chronic lymphadenopathy). Using molecular methods (real-time and traditional PCR), we assessed the presence of Bartonella quintana DNA in black head lice collected from three locations in Sénégal. DNA from B. quintana was identified in 19 lice (6.93%) collected from 7 patients (7%) in Dakar. B. quintana-positive lice collected from three subjects were identified as clades C and A.     

Internal Medicine Residents’ Perceptions of Team-Based Care and its Educational Value in the Continuity Clinic: A Qualitative Study

BACKGROUND

In order to teach residents how to work in interprofessional teams, educators in graduate medical education are implementing team-based care models in resident continuity clinics. However, little is known about the impact of interprofessional teams on residents’ education in the ambulatory setting.

OBJECTIVE

To identify factors affecting residents’ experience of team-based care within continuity clinics and the impact of these teams on residents’ education.

DESIGN

This was a qualitative study of focus groups with internal medicine residents.

PARTICIPANTS

Seventy-seven internal medicine residents at the University of California San Francisco at three continuity clinic sites participated in the study.

APPROACH

Qualitative interviews were audiotaped and transcribed. The authors used a general inductive approach with sensitizing concepts in four frames (structural, human resources, political and symbolic) to develop codes and identify themes.

KEY RESULTS

Residents believed that team-based care improves continuity and quality of care. Factors in four frames affected their ability to achieve these goals. Structural factors included communication through the electronic medical record, consistent schedules and regular team meetings. Human resources factors included the presence of stable teams and clear roles. Political and symbolic factors negatively impacted team-based care, and included low staffing ratios and a culture of ultimate resident responsibility, respectively. Regardless of the presence of these factors or resident perceptions of their teams, residents did not see the practice of interprofessional team-based care as intrinsically educational.

CONCLUSIONS

Residents’ experiences practicing team-based care are influenced by many principles described in the interprofessional teamwork literature, including understanding team members’ roles, good communication and sufficient staffing. However, these attributes are not correlated with residents’ perceptions of the educational value of team-based care. Including residents in interprofessional teams in their clinic may not be sufficient to teach residents how team-based care can enhance their overall learning and future practice.KEY WORDS: interprofessional collaboration, graduate medical education, qualitative research, primary care     

Clinical-epidemiological study of leptospirosis in humans and reservoirs in Yucatán,México

A leptospirosis clinical-epidemiological study was made in humans and reservoirs in the state of Yucatán, México. Interviews and serological analyses were made on 400 persons from an open population, 439 probable cases of leptospirosis and 1060 animal reservoirs (cows, pigs, dogs, rats and opossums). IgM Leptospira Dipstick and Microscopic Agglutination Test (MAT) was used to detect human antibodies to leptospiras and serovar respectively. Leptospirosis incidence in humans was 2.2/100,000 inhab. in 1998, 0.7/100,000 in 1999 and 0.9/100,000 in 2000. Overall seroprevalence was 14.2%, relatively unchanged from seroprevalences observed 20 years ago. Highest seropositivity was found in people over 56 years of age, predominating males over females. Predominant serovars in the open population were tarassovi, hardjo, pomona and panama. Leptospirosis cases were most frequent in rural areas, and the anicteric course predominated over the icteric. The panama, icterohaemorrhagiae and pomona serovars predominated in both anicteric and icteric courses. Dogs, pigs and rodents had the highest seropositivity among the reservoirs. Contact with rodents and natural water sources were significant factors (p < or = 0.05). Human cases (74%) occurred during the rainy season. It is concluded that leptospirosis is still a serious illness with important clinical and epidemiological implications in the state of Yucatán, Mexico.     

Alternative Approaches to Ambulatory Training: Internal Medicine Residents’ and Program Directors’ Perspectives

BACKGROUND  Internal medicine ambulatory training redesign, including recommendations to increase ambulatory training, is a focus of national discussion. Residents’ and program directors’ perceptions about ambulatory training models are unknown. OBJECTIVE  To describe internal medicine residents’ and program directors’ perceptions regarding ambulatory training duration, alternative ambulatory training models, and factors important for ambulatory education. DESIGN  National cohort study. PARTICIPANTS  Internal medicine residents (N = 14,941) and program directors (N = 222) who completed the 2007 Internal Medicine In-Training Examination (IM-ITE) Residents Questionnaire or Program Directors Survey, representing 389 US residency programs. RESULTS  A total of 58.4% of program directors and 43.7% of residents preferred one-third or more training time in outpatient settings. Resident preferences for one-third or more outpatient training increased with higher levels of training (48.3% PGY3), female sex (52.7%), primary care program enrollment (64.8%), and anticipated outpatient-focused career, such as geriatrics. Most program directors (77.3%) and residents (58.4%) preferred training models containing weekly clinic. Although residents and program directors reported problems with competing inpatient-outpatient responsibilities (74.9% and 88.1%, respectively) and felt that absence of conflict with inpatient responsibilities is important for good outpatient training (69.4% and 74.2%, respectively), only 41.6% of residents and 22.7% of program directors supported models eliminating ambulatory sessions during inpatient rotations. CONCLUSIONS  Residents’ and program directors’ preferences for outpatient training differ from recommendations for increased ambulatory training. Discordance was observed between reported problems with conflicting inpatient-outpatient responsibilities and preferences for models maintaining longitudinal clinic during inpatient rotations. Further study regarding benefits and barriers of ambulatory redesign is needed.
