[Oral health as the mirror of health: the primary care medicine's poor relative?]

Oral health (OH) is indivisible from general health. Several studies have established the link between morbi-mortality, especially cardiovascular, and bad OH, particularly in the case of edentation. Regrettably, part of the population choses dental care renunciation for financial reasons. The primary care physician (PCP), as the health professionnal with the most frequent and intense contacts with the patients, plays an important role to reinforce prevention measures, OH maintenance and to detect oral pathologies. To fulfill this mission, he has to be trained to endo-buccal examination. Furthermore, both the PCP and the dentist have to proactively build an interprofessional approach to promote patients' OH.

[Should we screen and treat subclinical hypothyroidism?]

Subclinical hypothyroidism, defined as an elevated thyroid stimulating hormone and normal thyroxine level, is common with aging, particularly after 65 years old. This condition is potentially associated with important consequences, such as cardiovascular diseases and cognitive disorders. So far, indications for screening and thyroxine replacement therapy are still controversial. In this review, we examine the data on those risks and the potential benefits of the treatment. We also present a large European randomized clinical trial that should clarify this controversy, in order to improve clinical care of patients with subclinical hypothyroidism and to give reliable data on maintaining good health among the elderly.

Thrombotic microangiopathic syndromes associated with drugs, HIV infection, hematopoietic stem cell transplantation and cancer

Thrombotic microangiopathy (TMA) has multiple etiologies. In the four disorders described in this review, the primary organ involved is the kidney. Drug-associated TMA can be an acute, immune-mediated disorder or the result of gradual, dose-dependent toxicity. TMA may occur in patients with advanced HIV infection, possibly mediated by angio-invasive infections. TMA following allogeneic hematopoietic stem cell transplantation may also be caused by drug toxicity; the pathogenesis may involve inhibition of vascular endothelial cell growth factor in renal podocytes. Malignancies of many types with systemic microvascular involvement may cause TMA. Recognition that these syndromes may mimic TTP is important to provide appropriate management and to avoid the inappropriate use of plasma exchange treatment.

[Fetal programming of cardiovascular disease: new causes and underlying mechanisms]

There exists an association between pathologic events occurring during early life and the development of cardiovascular disease in adulthood. For example, transient perinatal hypoxemia predisposes to exaggerated hypoxic pulmonary hypertension and preeclampsia predisposes the offspring to pulmonary and systemic endothelial dysfunction later in life. The latter finding offers a scientific basis for observations demonstrating an increased risk for premature cardiovascular morbidity in this population. Very recently, we showed that offspring of assisted reproductive technologies also display generalized vascular dysfunction and early arteriosclerosis. Studies in animal models have provided evidence that oxidative stress and/or epigenetic alterations play an important pathophysiological role in the fetal programming of cardiovascular disease.

Traumatic brain injury in children

The general practitioner has an important role in the acute management and during the rehabilitation process of children after a traumatic head injury. Latest research shows that sequelae may occur even after a mild head injury without loss of consciousness. Recognizing the warning signs and symptoms after a head injury allows the general practitioner to counsel the child and parents in secondary prevention, particularly in order to avoid any further head injury during the recovery phase. Under the supervision of the general practitioner, a gradual progressive return to the child's everyday activities optimizes the chances of a rapid and complete recovery.

[New european guidelines for dyslipidemia]

Lifestyle changes should be considered before anything else in patients with dyslipidemia according to the new guidelines on dyslipidemias of the European Society of Cardiology (ESC) and the European Atherosclerosis Society (EAS). The guidelines recommend the SCORE system (Systematic Coronary Risk Estimation) to classify cardiovascular risk into four categories (very high, high, medium or low risk) as the basis for treatment decisions. HDL cholesterol, which is inversely proportional to cardiovascular risk, is included to the total risk estimation. In addition to calculating absolute risk, the guidelines contain a table with the relative risk, which could be useful in young patients with a low absolute risk, but high risk compared to individuals of the same age group.
