Purpose This study aims to investigate the outcome of shunt surgery in patients with idiopathic normal pressure hydrocephalus (iNPH) in relation to age at surgery, using data from the Swedish Hydrocephalus Quality Registry (SHQR). The disease affects older patients, with a mean age at diagnosis of 74 years. Since shunt surgery, which introduces a risk of serious complications, is the only available treatment, appropriate selection of patients eligible for surgery is essential. It has been suggested that higher age negatively affects outcome after shunt surgery. Methods Patients operated upon during January 2004–February 2022 were included. The inclusion criteria were: age ≥ 60 years and data available from ≥ 3 domains by the iNPH scale. Clinical outcomes were assessed at 3 and 12 months using the modified version of the iNPH scale (miNPH), the Timed Up-and-Go (TUG) test and the modified Rankin scale (mRS). These were related to 5-year-interval age groups. Results Improvement was seen in all age groups, with no statistically significant differences in outcome between age groups in miNPH score, TUG or mRS. The oldest group (> 85 years) showed significant improvements, as illustrated by miNPH scale score changes at 3 and 12 months of 4.3 (–8.1 to 21.5) and 10.1 (–6.5 to 36.8), respectively. Conclusions This population-based study shows similarly favourable outcomes across ages, suggesting that there should be no upper age limit for shunt surgery in patients with iNPH.

In this trial of preexposure prophylaxis with tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) in men who have sex with men, TDF-FTC was found to be effective in preventing HIV-1 infection when it was taken before sexual activity. The prevention of infection with human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) remains a major public health challenge. 1 Owing to the lack of an effective HIV vaccine, consistent condom use remains the cornerstone of prevention, but biomedical interventions such as male circumcision and the use of antiretroviral drugs for the treatment of HIV infection represent additional prevention strategies. 2 – 5 Among the promising interventions is preexposure prophylaxis, in which antiretroviral drugs are started in HIV-negative persons before potential exposure to the virus. Daily oral preexposure prophylaxis with either tenofovir disoproxil fumarate (TDF) or the combination of TDF and . . .

BK virus (BKV) reactivation has been increasingly associated with the occurrence of late-onset hemorrhagic cystitis (HC) after allogeneic hematopoietic SCT (allo-HSCT) resulting in morbidity and sometimes mortality. We investigated the incidence, risk factors and outcome of BKV-HC in 323 consecutive adult patients undergoing allo-HSCT over a 5-year period. BK viremia values for HC staging were evaluated, as well as the medico-economic impact of the complication. Forty-three patients developed BKV-HC. In univariate analysis, young age ( P =0.028), unrelated donor ( P =0.0178), stem cell source ( P =0.0001), HLA mismatching ( P =0.0022) and BU in conditioning regimen ( P =0.01) were associated with a higher risk of developing BKV-HC. In multivariate analysis, patients receiving cord blood units (CBUs) ( P =0.0005) and peripheral blood stem cells ( P =0.011) represented high-risk subgroups for developing BKV-HC. BK viremia was directly correlated to HC severity ( P =0.011) with a 3 to 6-log peak being likely associated with grades 3 or 4 HC. No correlation was found between BKV-HC and acute graft versus host disease or mortality rate. Patients with BKV-HC required a significantly longer duration of hospitalization ( P <0.0001), more RBC ( P =0.0003) and platelet transfusions ( P <0.0001). Over the 5-year study period, the financial cost of the complication was evaluated at €2 376 076 ($3 088 899). Strategies to prevent the occurrence of late-onset BKV-HC after allo-HSCT are urgently needed, especially in CBU and peripheral blood stem cell recipients. BK viremia correlates with the severity of the disease. Prospective studies are required to test prophylactic approaches.

There have been many epidemiological studies of chickenpox but only a few of herpes zoster. We report data from an observational study, conducted in France during a 1-year period, of 9038 patients who presented with acute herpes zoster (n = 8103) or postherpetic neuralgia (PHN; n = 935) at the office practices of 4635 general practitioners or dermatologists. The incidence of herpes zoster in France was found to be similar to that in the literature: from 1.4 to 4.8 cases per 1000 population per year. The patient profiles and clinical patterns were delineated, as well as the management decisions made according to the type of treating physician. The impact of herpes zoster on quality of life was evaluated on the basis of the Medical Outcome Study Short Form 36 (MOS SF 36) scale, which is widely used for assessing quality of life in the field of health. This study provides reference data on the substantial deterioration in quality of life associated with herpes zoster and PHN.

Health-care authorities encouraged A(H1N1)2009 influenza vaccination for all hospital workers because of their high risk of contracting and transmitting the virus. Six months after the vaccination campaign began, an electronic anonymous questionnaire was completed by 1630 among 14,000 hospital workers (11.6%). Vaccination rate was 54.3%. Independent predictors for vaccination acceptance were advanced age (OR=1.61–2.19), being a physician (OR=5.07), working in gynaecology-obstetrics or podiatry (OR=1.62), and having been informed about vaccination (OR=2.78). The main reasons for getting vaccinated were to avoid flu for relatives (82.4%), themselves (65.8%) and patients (57.1%). Arguments against vaccination were lack of sufficient studies of the vaccine (75.7%) and the perception of A(H1N1)2009 influenza as a benign disease (51.5%). Vaccination coverage would be insufficient to keep the health-care system operating at maximum capacity during a severe pandemic disease, and to avoid nosocomial transmission of influenza. These results suggest a better-targeted vaccination campaign.

To describe characteristics of infective endocarditis (IE) in pacemaker (PM) recipients, including the annual incidence and exact localization of IE on PM leads, cardiac valves, or both, we prospectively analyzed 45 PM recipients from a group of 559 patients with definite IE who responded to a population-based survey conducted in France in 1999. Thirty-three patients had definite PM-lead IE (group I), and 12 had valvular IE without evidence of PM involvement (group II). The valvular structure was involved in almost two-thirds of IE cases among PM recipients. Of the 28 patients (62%) with valvular IE, 10 group I patients had tricuspid involvement, and 6 group I patients had left heart-valve involvement. The most frequent causative organisms in groups I and II were staphylococci (82%) and streptococci (50%), respectively. The incidence of age- and sex-standardized IE was 550 cases/million PM recipients per year. The incidence of IE with PM involvement is between that of valvular IE in the general population and prosthetic valve IE.

The purpose of this paper is to describe the impact of exposure to influenza on hospitalizations and deaths in the elderly residents of long-term care facilities (LTCFs). An observational, longitudinal, prospective, multicenter, cohort study collected influenza and influenza-like cases, diseases, hospitalizations, and deaths of dependant elderly residents of French LTCFs during the 2004-2005 seasonal influenza epidemic. A total of 8,041 residents of 98 participating LTCFs were included. The mean age was 85 ± 9 years; 93% were vaccinated against influenza and 64% of the residents were exposed to influenza during the epidemic. Exposure to influenza increased both the all-cause risk of hospitalization (9.2% of the residents exposed vs. 7.4% of the residents not exposed) (relative risk, RR [95% confidence interval, CI] = 1.24 [1.05; 1.47]) and the all-cause risk of death (5.8% vs. 4.3%) (RR [95% CI] = 1.36 [1.10; 1.70]). Exposure to influenza increased the risks of death and hospitalization. Additional measures should be taken to avoid influenza exposure and apply recommendations more thoroughly in the particularly susceptible population of elderly LTCF residents.

Actinomycosis is a rare chronic disease caused by Actinomyces spp., anaerobic Gram-positive bacteria that normally colonize the human mouth and digestive and genital tracts. Physicians must be aware of typical clinical presentations (such as cervicofacial actinomycosis following dental focus of infection, pelvic actinomycosis in women with an intrauterine device, and pulmonary actinomycosis in smokers with poor dental hygiene), but also that actinomycosis may mimic the malignancy process in various anatomical sites. Bacterial cultures and pathology are the cornerstone of diagnosis, but particular conditions are required in order to get the correct diagnosis. Prolonged bacterial cultures in anaerobic conditions are necessary to identify the bacterium and typical microscopic findings include necrosis with yellowish sulfur granules and filamentous Gram-positive fungal-like pathogens. Patients with actinomycosis require prolonged (6- to 12-month) high doses (to facilitate the drug penetration in abscess and in infected tissues) of penicillin G or amoxicillin, but the duration of antimicrobial therapy could probably be shortened to 3 months in patients in whom optimal surgical resection of infected tissues has been performed. Preventive measures, such as reduction of alcohol abuse and improvement of dental hygiene, may limit occurrence of pulmonary, cervicofacial, and central nervous system actinomycosis. In women, intrauterine devices must be changed every 5 years in order to limit the occurrence of pelvic actinomycosis.
