[Medico legal issues related to driving: the role of the general practitionner]. / Restrictions médico-légales a la conduite automobile rôle du médecin généraliste.

The Belgian law requires that the physician informs his/her patient when he diagnoses a medical reason that makes him/her unfit to drive a vehicle. This paper lists, as they appear in the official texts, the physical conditions and diseases which may be responsible for the inaptitude to drive. Thus are detailed the rules applied in the presence of neurological diseases, psychic disorders, epilepsia, pathological sleepiness, locomotive disorders, cardiovascular disease, rhythm or conduction disturbances, blood pressure abnormalities, coronary or myocardial disease, and hearing loss or vestibular problems. The reader will also find a summary of the rules related to visual ability, alcohol use, driving under the influence of psychotropic drugs, or medicines in general, renal or hepatic diseases, and to the patient who received an organ transplant or an artificial implant. The responsibility of the physician, primarily the general practionner, may be involved in these matters; this issue is discussed.

[Management of intrafamily violence issues by general practitioners]. / Gestion sur le terrain de la violence intra-familiale par le médecin généraliste.

General practitioners often come upon intrafamily abuse cases in their practice. They are either specifically consulted because of these instances of abuse or they discover them by accident. When this happens, they are often unsure of the appropriate procedure to follow, for fear of committing a medical fault or breaking the law. The aim of this short article is not to dwell on the diagnostic methodologies, but to provide a series of general guidelines to follow in everyday practice.

A randomized, controlled pilot study of the safety and efficacy of 4% icodextrin solution in the reduction of adhesions following laparoscopic gynaecological surgery.

BACKGROUND: Adhesion-related readmissions are frequent sequelae to gynaecological surgery. Attempts to prevent adhesions by separating healing peritoneal surfaces include site-specific barriers and hydroflotation by instilled solutions. Rapid absorption limits the effectiveness of solutions such as Ringer's lactated saline (RLS). This pilot study assessed the safety, tolerability and preliminary effectiveness of a non-viscous, iso-osmolar solution of 4% icodextrin, an alpha-1,4 glucose polymer with prolonged intraperitoneal residence, in reducing adhesions after laparoscopic gynaecological surgery. METHODS: Women aged > or = 18 years, requiring laparoscopic adnexal surgery (n = 62), were entered into a randomized, open-label, assessor-blinded, multicentre study to compare 4% icodextrin with RLS. Treatments were coded in blocks of four with equal randomization to each group, and pre-allocated to consecutively numbered patients. At least 100 ml per 30 min was used for intra-operative lavage, with 1 l instilled post-operatively. Per protocol analysis included all eligible patients (n = 53); reformation analysis required one or more baseline adhesion (n = 42). Incidence, extent and severity of post-operative adhesions were assessed at second-look laparoscopy after 6-12 weeks. Procedures were video-taped for third party, blinded assessment. RESULTS: Safety and tolerability (laboratory variables, adverse events, clinical follow-up) were good with no difference between treatments. A shift analysis of incidence-ranked adhesions (n = 53) showed apparent improvements in more patients with icodextrin than RLS (37 versus 15%; not significant). Adhesion score reduction (n = 42) was more frequent in icodextrin- than RLS-treated patients: incidence (52 versus 32%), extent (52 versus 47%), and severity (65 versus 37%). Despite greater baseline adhesions, median reformation was less after icodextrin (24%) than RLS (60%). The pilot study group sizes were not powered for statistical significance. CONCLUSIONS: In this preliminary study, 4% icodextrin lavage plus instillation was well tolerated and reduced adhesion formation and reformation following laparoscopic gynaecological surgery. A Phase III pivotal study is currently in progress.

Mechanisms of cellular insulin resistance in human pregnancy.

OBJECTIVES: The cellular mechanism(s) of insulin resistance developed during pregnancy were studied by investigating the functionality of insulin receptors and glucose transport. STUDY DESIGN: Abdominal adipose tissue was obtained from eight lean pregnant and nine control subjects, matched for insulin resistance by intravenous glucose tolerance testing. Insulin receptor binding and glucose transport were measured in freshly isolated adipocytes. Receptor kinase activity was measured on partially purified receptors. Data were analyzed by Student t test. RESULTS: High-affinity insulin receptors were reduced in cells from pregnant compared with normal controls (2.0 +/- 0.4 vs 5.8 +/- 1.3 x 10(4) sites per cell, p < 0.05). Kinase activity of insulin receptors was unaltered in pregnancy. Adipocytes from pregnant subjects displayed a threefold decrease in insulin sensitivity for glucose transport (median effective concentration 324 +/- 93 vs 93 +/- 14 pmol/L, p < 0.025) and a reduction in maximal insulin-stimulated glucose transport (1.58 +/- 0.15 vs 2.33 +/- 0.24 pmol/10(5) cells/10 seconds, p < 0.025). CONCLUSIONS: These results show that adipocytes from pregnant subjects exhibit decreased insulin receptor number and an impaired insulin sensitivity in the absence of functional alterations of receptor kinase activity.
