Radiation-induced aneurysm of the cavernous internal carotid artery

We report a case of intra-cranial aneurysm of the left cavernous internal carotid artery occurring 27 years after radiotherapy of the pterygopalatine fossa for Hodgkin disease. The development of the aneurysm within the irradiation field, the long latency after radiotherapy, the normality of carotid angiography before radiotherapy and the absence of other etiologies led to the diagnosis of radiation-induced aneurysm. The main characteristics of radiation-induced intra-cranial aneurysms are reviewed.     

Length of hospital stay, discharge planning, and policy regarding the shortening of hospital stays: patients'and hospital care providers'point of view

BACKGROUND: In the context of health care cost containment, we interviewed hospitalized patients and their health care teams concerning the length of stay they considered necessary and hospital discharge. Patients were also interviewed on the present tendency to shorten hospital stays. METHODS: Prospective study conducted in a subacute internal medicine ward with 254 consecutive patients and their health care teams. RESULTS: The mean evaluation of the length of stay considered as necessary was not significantly different between patients (9.7 days, SD=9.5) and their health care teams (9.6, SD=8.5). However, agreement between the two parties was moderate (r=0.64). Hospital discharge was considered as planned in similar proportions (18% vs 22% respectively), but was reported as more 'assured' by health care teams than by patients (p<0.001). Health care teams and patients approved discharge planning in 200 cases (63.3%), but agreement was only moderate (Kappa 0.43, IC 95%=0.34-0.51). Regarding the tendency to shorten hospital stays, patients'responses were favorable in only 9%, clearly unfavorable in 17% and disclosed explicit fears in 54% of the cases. CONCLUSIONS: These results show that what patients and health care teams consider the necessary length of stay and the right time for hospital discharge can diverge notably. They highlight the difficulties of medical decisions in the context of cost containment, and the fundamentally asymmetrical character of the relationship between patients and health care teams.     

Prevalence and comorbidity of psychiatric disorders in the French general population

INTRODUCTION: ESEMeD is the first international epidemiological study using a random sampling method that has allowed the prevalence of psychiatric disorders in France to be measured with precision and compared directly with that observed in other European countries. OBJECTIVES: 1) To determine the 12 month and lifetime prevalence of mood -disorders, anxiety disorders and alcohol-related disorders. 2) To estimate the comorbidity between these disorders. 3) To evaluate potential demographic risk factors for these disorders. METHODS: This was a transversal survey carried out between 2001 and 2003 of non-institutionalised subjects aged 18 or over in the general population of Germany (n = 3,555), Belgium (n = 2,419), Spain (n = 5,473), France (n = 2,894), the Netherlands (n = 2,372) and Italy (n = 4,712). In France, the sampling source was a randomly generated list of telephone numbers. Subjects were interviewed at home by professional interviewers. The WMH-CIDI questionnaire was used. RESULTS: The participation rate was 46% for France and 61% for all six countries combined. The 12 month and lifetime prevalence rates observed were respectively 6.0% and 21,4% for major depressive episodes, 1.6% and 7.9% for dysthymia, 2.1% and 6.0% for the generalised -anxiety disorders, 1.2% and 3.0% for panic disorders, 0.6% and 1.8% for agoraphobia, 2.2% and 3.9% for post-traumatic stress disorder, 1.7% and 4.7% for social phobia, 4.7% and 11,6% for specific phobia, 0.5% and 4.1% for alcohol abuse and 0.3% and 1.6% for alcohol dependence.Mood disorders and anxiety disorders were significantly more frequent in women, whilst alcohol-related disorders were more frequent in men. The prevalence of all three types of disorder was lower in elderly subjects and in those living in a rural environment. Mood disorders and alcohol-related disorders were more frequent in individuals living alone and mood disorders more frequent in those without paid employment. 38% of subjects with mood disorder also presented an anxiety disorder or an alcohol-related disorder. The comorbidity of mood and anxiety disorders was more frequent in women, younger subjects and those living alone. The comorbidity rate in subjects with anxiety disorders was 26% and did not differ between genders. For alcohol-related disorders, there was a striking difference in comorbidity rate between men and women: 26% in the former and 67% in the latter. CONCLUSION: This study underlines the high prevalence of mood disorders, anxiety disorders and alcohol-related disorders in France and demonstrates a high degree of comorbidity between them. For this reason, it is important to evaluate and take into account potential comorbidity in the management of individuals with psychiatric disorders.     

Pulsatile ocular blood flow of choroidal neovascularization in asymmetric age-related macular degeneration after transpupillary thermotherapy

PURPOSE: A previous study has shown that the pulsatile ocular blood flow (POBF) in eyes with asymmetric age-related macular degeneration (AMD) differs. Whereas eyes with drusen have higher POBF than contralateral eyes with disciform scarring, the POBF of eyes with drusen is lower relative to contralateral eyes with choroidal neovascularization (CNV). This study was designed to assess whether the POBF of eyes with CNV changes after transpupillary thermotherapy (TTT), using the contralateral eyes with drusen or scarring without TTT as controls. METHODS: In total, 26 patients with CNV in one eye and drusen or scarring in the other were enrolled in this prospective case series. Eyes with CNV were treated with TTT. POBF was measured monthly in both eyes of each subject. RESULTS: Before TTT, the POBF of eyes with CNV was 1179+/-317 microl/min. After TTT, the POBF of CNV eyes had decreased at 1 month (1015+/-273 microl/min, P=0.002) and 2 months (945+/-398 microl/min, P=0.011) of follow-up, but had rebounded at 3 months (P=0.441) and 6 months (P=0.084). CONCLUSIONS: These findings suggest that TTT decreases the pulsatile choroidal blood flow in eyes with CNV in patients with asymmetric AMD and the effects persist for 2 months. POBF may be used as a modality to monitor the therapeutic effects of CNV in asymmetric exudative AMD.     

Effect of Near-Total Thyroidectomy on Thyroid Orbitopathy Due to Toxic Goiter

Background  The relative merit of surgery in the treatment of Graves’ ophthalmopathy as well as the extent of surgical resection are still matters of debate. This study aimed at reporting an assessment of the impact of near-total thyroidectomy on the course of ophthalmopathy including exophthalmos. Methods  A total of 20 patients with thyrotoxic goiters who were suffering from mild to moderate exophthalmos were enrolled in this prospective study. Preoperative evaluation of ophthalmopathy was accomplished through the NOSPECS classification, magnetic resonance imaging (MRI) for measuring the extraocular muscle diameters, and measurement of the exophthalmos using Hertel’s exophthalmometer. Ophthalmopathy including exophthalmos was reevaluated 6 months after operation using the same parameters. Results  Clinical activity evaluation, exophthalmometry, and extraocular muscles measurement by MRI revealed that most of the patients experienced improvement of their ophthalmopathy (65%). This improvement was statistically significant. In addition, no major postoperative complications were observed. However, the study, unlike a number of reported retrospective ones, failed to specify any statistically significant prognostic factors affecting the course of ophthalmopathy; this may have been due to the limited number of patients. In addition, all of the patients were of relatively young age and thyrotoxic, and most were female and nonsmoking. Conclusions  In addition to the fact that near-total thyroidectomy adds the advantages of total thyroidectomy (no recurrence) to those of subtotal thyroidectomy (low incidence of temporary and permanent hypoparathyroidism), it has a significant positive impact on thyroid-associated orbitopathy.     

New therapeutic approaches in glioblastomas

Current treatment of glioblastomas relies on surgical resection, radiotherapy and chemotherapy. However, the efficacy of these therapeutics is still limited and new therapeutic approaches based on the understanding of brain tumor biology are emerging. High expression of the EGF receptor by tumor cells, activation of the PI3K/Akt and the Ras/Raf pathways represent interesting targets for new selective drugs under development. The most promising drugs are currently antiangiogenic agents. This article reviews these emerging therapies currently under clinical trials in glioblastomas.     

Relationship between the level of antibodies in bulk tank milk and the within-herd seroprevalence of Coxiella burnetii in cows

The relationship between the level of antibodies in bulk tank milk (BTM) and the within-herd seroprevalence of Coxiella burnetii in cows was assessed. Blood from milking cows and BTM were sampled in 55 infected herds and tested using commercial enzyme-linked immunosorbent assay (ELISA) kits. The relationship between antibody levels and WHP, which was quantified using a general linear model, was only moderate (R(2)=0·15). Nevertheless, the lowest antibody level in BTM was associated with the lowest mean within-herd prevalence. The present finding indicates that ELISA applied to BTM could identify infected herds with quite low within-herd seroprevalence. For such herds, the vaccination of dairy cows as well as nulliparous heifers using a phase I vaccine could effectively prevent C. burnetii shedding.     

Effect of raised lung volume technique on subsequent measures of V'maxFRC in infants

Partial and "full" forced expiratory maneuvers are both used to assess airway function in infants. Despite the increasing use of the raised volume technique, there is little information regarding the influence of lung inflations as are necessary for the raised volume technique on other measurements of lung function in infants. The aim of this study was to assess whether application of the raised volume technique influences subsequent tidal measurements of maximal expired flow at functional residual capacity (V'maxFRC). Paired measurements of V'maxFRC were obtained in 29 healthy infants (aged 6-65 weeks) before and after raised volume maneuvers, wherein a lung inflation pressure of 3 kPa was used. When compared with measurements prior to raising lung volume, there was a highly significant (P < 0.001) decrease in V'maxFRC by 40 ml.sec(-1) when measurements were repeated (95% CI, -59, -20 ml.sec(-1)), equivalent to a reduction of 20% or -0.6 SD scores in flows. There was no significant change in selected tidal breathing parameters, 95% CI of differences between the two sets of measurements being -1.5, 1.2 bpm for respiratory rate; -0.5, 0.2 ml.kg(-1) for weight corrected tidal volume, and -0.04, 0.01 for tidal breathing ratio (tPTEF:tE). In conclusion, although the mechanism remains unclear, raised volume maneuvers may influence subsequent measures of lung function in infants. Further research is needed to clarify the potential mechanisms. In the meantime, the potential impact of the order of lung function tests within any given study protocol should be considered carefully.
