Diving-related fatalities caused by underwater explosions: a report of two cases.

The authors report two cases of diving-related water blast with fatal outcome resulting from nearby underwater explosions. Water blast with fatal outcome almost exclusively occurs in wars at sea. Underwater explosions are extremely rare in diving because of the limited exposure. Forensic findings in both cases reported included expected injuries to gas-filled organs such as the middle ear, lungs, and intestine; some rarely described injuries such as rupture of the liver, spleen, and kidneys; and also some lesions that were not found in a search of the literature: rupture of the heart and contusion of the hypophysis. Injuries caused by fatal underwater explosions should be carefully evaluated in forensic medicine to provide data that may support a criminal investigation.

Histopathology and immunopathology of skin biopsy specimens in Mediterranean spotted fever.

Histology of skin lesions and demonstration in them of Rickettsia conorii by direct immunofluorescence test (DIF) are presented in 13 patients with Mediterranean spotted fever (MSF). The lymphohistiocytic vasculitis which dominated the picture is not specific, however, it could be suggestive for the diagnosis of rickettsiosis. By DIF we demonstrated rickettsial coccobacillary forms in all the patients: in 12 macular lesions and in one "tache noire". The diagnosis was also confirmed by indirect immunofluorescence test in each case. DIF test was shown to be sensitive, specific and reliable in early diagnosis of MSF.

[Patho-anatomic changes in a narcotic addict].

The pathoanatomical analyses made on biopsy specimens of organs of a woman with a several year history of drug abuse who died suddenly because of drug intoxication is presented. Characteristic pathological findings such as scars on the forearm arranged in a series along the vein as well as fresh needle marks in the cubital region suggesting intravenous drug use are described. Birefringent talc crystals as a positive sign of drug addiction were found in macrophages of the lungs, liver, spleen and kidneys. In the lungs, they were present perivasculary within the foreign-body granulomas, in the liver, within the Kupffer's cells and macrophages of the porta hepatis, in the spleen, in macrophages around the folliculi and in the kidneys within the endothelial cells of glomerular loops. The liver showed chronic viral hepatitis as well. As a sign of an acute drug intoxication, the so-called "drug addict's lung" was observed and the brain showed a pronounced edema and perivascular bleeding. The mentioned acute pathological changes demonstrate that the sudden death was most probably caused by drug intoxication and this has been confirmed by toxicological analysis. In summary, the value of the necroscopy and histological analysis of organs, particularly by using a polarizing microscope, in detecting pathological changes caused by drug addiction and, thus, the need for pathoanatomical analysis of all drug addicts who expired and young persons who died by a sudden death of unknown origin is emphasized.

[Factors contributing to the onset of heart rupture in acute infarct].

The aim of this study was to find out the contributing factors for cardiac rupture in the course of acute myocardial infarction (AMI). Past medical histories and autopsy data of 80 patients were analyzed. The first group consisted of 30 patients who died due to heart rupture in the course of AMI and the control group of 50 patients who died from the other, more common complications of AMI. There was no difference between the groups according to age and sex of the patients. All patients who died from the rupture of the heart had a history of heavy chest pain, while it was lacking in 30% of the patients of the control group (p less than 0.01). All the first group patients showed electrocardiograms diagnostic for AMI, while it was lacking in 14% of the second group patients (p less than 0.05). Almost a half of the second group patients (47%) were in the class I of the Killip's classification, while only 20% of the control group did not developed left ventricular failure. Pathological study showed that the rupture of the heart most commonly occurred in the course of an anterior myocardial infarction. There was no difference according to the size of infarctions between observed groups, but the thickness of the left ventricular wall was significantly less (p less than 0.05) in the control group, and the heart weights were higher (p less than 0.05) in the control group. There was advanced atherosclerosis of the coronary arteries and about two thirds of the first group patients showed acute coronary thrombosis.(ABSTRACT TRUNCATED AT 250 WORDS)
