[Herpes simplex hepatitis with macrophage activation syndrome in an immunocompetent patient].
Herpes simplex hepatitis is a rare cause of acute hepatitis in immunocompetent patients. The triad of fever, increase in liver enzymes and leucopenia is suggestive of herpes simplex hepatitis. Delayed diagnosis without antiviral therapy contributes significantly to an unfavorable outcome. ⋯ Despite its relatively low occurrence rate, diagnosis of herpetic hepatitis should be discussed in immunocompetent patients with acute liver failure. The benefit of an early acyclovir treatment should lead clinicians to consider this uncommon diagnosis in unexplained cases of hepatitis and to test rapidly HSV DNA levels by PCR in plasma.

In the context of the French National Health Service, a free access to healthcare facilities (the PASS: "permanence d'accès aux soins de santé") has been implanted in 2000 for patients without health insurance or those dealing with financial hardship. There is few data about socio-demographic characteristics of the patients using these services. The objective of this study was to provide descriptive data about socio-demographic characteristics and motivation of those patients who use these clinics. ⋯ The findings of this study suggest that the PASS carry out their mission: most of the patients frequenting these facilities live under poor conditions and are in poor health status compared to the patients having access to conventional outpatient services.

Over the past decades, the incidence and the number of hospital admissions for acute pancreatitis have increased in the Western countries. The two most common etiological factors of acute pancreatitis are gallstones (including small gallstones or microlithiasis) and alcohol abuse. Acute pancreatitis is associated with a significant mortality (4-10%) and 25% in case of pancreatic necrosis, especially. ⋯ The incidence trends of acute pancreatitis possibly reflect a change in the prevalence of main etiological factors (e.g. gallstones and alcohol consumption) and cofactors such as tobacco, obesity and genetic susceptibility. Priority is to search for associated causes, especially in cases with atypical symptoms. In case of first acute pancreatitis in patients older than 50 years, the presence of a tumor (benign or malignant) has to be specifically ruled out, using CT-scan, MRI and endoscopic ultrasound.

Obstructive sleep apnea syndrome is a chronic disease characterized by repeated upper airway obstructions during sleep, resulting in fragmented sleep with arousals, nocturnal intermittent hypoxemia and diurnal dysfunctions. Despite its high prevalence in elderly, sleep apnea syndrome seems to be underestimated and difficult to be recognized because of the lack of clinical symptoms specificity in this population. Among the numerous consequences of the obstructive sleep apnea syndrome, cognitive impairment prevails on the attention, executive functions and memory. ⋯ In this context, the question arises whether obstructive sleep apnea syndrome is a possible etiological or aggravating factor of cognitive decline in elderly with mild cognitive impairment or Alzheimer's disease. Although there are conflicting results in studies evaluating therapeutic efficiency of continuous positive air pressure, obstructive sleep apnea syndrome seems nevertheless as a correctable factor, at least for its impact on some cognitive consequences. Looking for sleep apnea syndrome in elderly with cognitive decline should be considered in a global, diagnosis and therapeutic management.

Adulterants are compounds added to street drugs to increase profits for the seller. Levamisole, a veterinary antihelminthic agent, has become the most common adulterant of cocaine. The prevalence of levamisole in samples of cocaine is increasing. Levamisole can lead to neutropenia and to a dramatic vasculopathy and even vasculitis of small and medium-size blood vessels. ⋯ Clinicians should be aware that agranulocytosis or vasculitis or vasculopathy could be related to levamisole toxicity in individuals who use cocaine.
