La prise en charge du malade et de la maladie doit être globale.

Amussat's sign is a transverse laceration of the intimal layer of the carotid arteries. It is known to be strongly suggestive of hanging. The discovery of this sign in a body recovered from water can arise several questions from a legal point of view. In this paper, we report a case of a drowned body with Amussat's sign. A 41 year-old man was found dead face down in a ten-meter-deep well with a water level of four meters. He has medical history of psychiatric illness and he has stopped his medication in the preceding period. Autopsy revealed Amussat's sign at the level of the two carotid arteries. The medico-legal value and the mechanism of this sign will be discussed.

Les infiltrations de corticostéroïdes dans le traitement des kystes synoviaux est de pratique courante dans le domaine thérapeutique. Cet acte, réputé anodin, n’est pas à l’abri de survenue d’incidents pouvant induire des séquelles fonctionnelles. Dans ce contexte, nous rapportons un cas de rupture d’un tendon extenseur de la main faisant suite à une injection locale de corticostéroïdes et nous discutons les implications médicolégales ainsi que la responsabilité du médecin traitant.

Electrical injuries consist mainly in external burn marks. Internal injuries are rarely observed especially in low-voltage electrocution. In this context, we report two fatal cases due to electrocution by low voltage current (220 volts), with a special emphasis on pathological internal changes.

Myocardial abscess (MA) is a life-threatening condition, where the early detection and the initiation of adequate therapy are crucial for the patient's survival. MA is generally related to either septic emboli or endocarditis. Its occurrence at an infarct site is uncommon and has been rarely reported in the literature. We herein report an autopsy case of a 57-year-old male, without any known past medical history, who was found dead at home. A medico-legal autopsy was conducted. The external examination of the body showed facial cyanosis with no traumatic lesions. The autopsy findings included pulmonary edema and visceral congestion. The heart weighed 420g and the body weight was 88kg. Examination of the valvular structures was normal. There was a critical atherosclerosis of the left anterior descending artery with a narrowing of more than 90%. Serial biventricular section of the heart, revealed an heterogeneous area on the anterior wall of the left ventricle, measuring 1cm in diameter, containing both an infarction myocardial zone and fibrous ischemic scar. Microscopic examination showed a well-circumscribed, destructive lesion with central necrotic debris with numerous neutrophils surrounded by a rim of granulation tissue and mixed inflammatory infiltrates which is consistent with the diagnosis of a myocardial abscess. PAS staining was negative. Histologically, there was no evidence of abscess in other organs. The troponins I in the pericardial fluid were high. Toxicological analysis and postmortem blood culture were performed with negative results. The cause of death was attributed to an arrhythmia secondary to a myocardial infarction complicated with a myocardial abscess.

Hypocotyl, cotyledon and zygotic embryo explants from two Tunisian Cucumis meloL. cultivars Beji and Maazoun, cultured on the MS medium added with 2,4-D(0.25–1 mg l−1) and BA (0.10–0.50 mg l−1), produce calluses with somatic embryos after 3 weeks of culture. For Beji c.v. the highest percentage (62.50%) of embryogenesis was observed for cotyledons. The average embryo number per callus was 10.40. Embryogenesis induction for zygotic embryos reached 33.50% with 29 embryos per callus. The embryogenesis ability of hypocotyls did not exceed 12.50% (2.50 embryos per callus). Somatic embryogenesis for Maazoun c.v. explants was less efficient. Embryos formation was observed only for cotyledons (29%) and zygotic embryos (25%). Cotyledonary staged embryos, when transferred to hormone free MS medium, germinated. The maximum germination rates were 51.50 and 44.50%, respectively for Maazoun and Beji c.v. The highest percentage (36.50%) of survival plants was noted for Beji c.v. Regenerants were diploids (2n= 2x= 24) and morphologically similar to their parents issued from seeds.Hypocotyl, cotyledon and zygotic embryo explants from two Tunisian Cucumis meloL. cultivars Beji and Maazoun, cultured on the MS medium added with 2,4-D(0.25–1 mg l−1) and BA (0.10–0.50 mg l−1), produce calluses with somatic embryos after 3 weeks of culture.
