Strong evidence for age as the single most dominant predictor of medically supervised driving test-mini mental status test outcomes provide only weak but significant moderate additional predictive value.

Background: With age, medical conditions impairing safe driving accumulate. Consequently, the risk of accidents increases. To mitigate this risk, Swiss law requires biannual assessments of the fitness to drive of elderly drivers.

[Daytime Sleepiness in Patients with Restless Legs Syndrome: A Risk Factor for Traffic Accidents?].

Daytime Sleepiness in Patients with Restless Legs Syndrome: A Risk Factor for Traffic Accidents? Abstract. Restless legs syndrome (RLS) is a symptom complex of predominantly leg-focused paraesthesias and the associated increased urge to move. Since evening exacerbations are typical, many patients suffer from sleep disorders, which can lead to increased daytime fatigue in the long term.

Matricides in South Australia - a 20-year retrospective review.

A 20-year retrospective review of files at Forensic Science SA, Adelaide, Australia was undertaken for cases of matricide occurring between the years 1985 and 2004. A total of 11 cases were identified: 10 males and 1 female. The victims were aged between 42 and 83 years (mean=61 years) and the perpetrators were aged between 15 and 53 years (mean=28.

Congenital mesenteric defects and unexpected death-a rare finding at autopsy.

Gastrointestinal causes of sudden and/or unexpected death in the young are uncommon and only rarely involve congenital anomalies of the mesentery. Two cases are reported of unexpected deaths following herniation of intestine through congenital mesenteric defects to illustrate the forensic issues that may arise. Case 1 involves a 2.

Histologic dating of bruises in moribund infants and young children.

It is generally held that leukocytes are found within bruised subcutaneous tissues within 4-12 h of injury as part of a standard cellular response to trauma. As a corollary, the absence of leukocytes is often cited as evidence of more recent injury. To investigate how long after injury it may be before a leukocyte response occurs selected bruises from three children aged 27, 11, and 3 months, respectively, were examined microscopically.

Is right coronary artery hypoplasia and sudden death an underdiagnosed association?

Determining whether hypoplasia of a coronary artery has caused or contributed to death is often complicated by an absence of histologic evidence of myocardial ischemia in the area of the heart supplied by the affected artery and also by the lack of data for assessing coronary artery size at autopsy. A 45-year-old woman is reported who collapsed and died and who was found at autopsy to have a dominant, small-caliber, right coronary artery, with acute and chronic ischemic changes in the posterior interventricular septum supplied by the diminutive vessel. This case provides evidence that small-caliber coronary arteries may be associated with a lethal outcome.

Fatal electrocution in adults--a 30-year study.

A retrospective study was undertaken of all cases of death in adults (>16 years) due to electrocution which were autopsied at Forensic Science SA, Adelaide, Australia, over a 30-year period from 1973 to 2002. A total of 96 cases were identified with 87 males (91%) (mean age=41.6 years; range 17 to 86 years) and nine females (9%) (mean age=49.

Mechanisms of unexpected death and autopsy findings in Leigh syndrome (subacute necrotising encephalomyelopathy).

A 21-year-old previously-well woman who was undergoing medical investigations for problems with balance and suspected multiple sclerosis, developed a headache and breathing difficulties, and died suddenly and unexpected at home. The autopsy was unremarkable except for pulmonary and cerebral oedema. However, subsequent microscopy of the brain revealed characteristic features of Leigh syndrome with multifocal areas of astrogliosis, capillary proliferation, and parenchymal vacuolation.

Café coronary syndrome-fatal choking on food: an autopsy approach.

To examine the characteristic features of fatal food asphyxia and to develop an autopsy approach to such cases a retrospective study of autopsy files was undertaken at Forensic Science SA (Adelaide, Australia) over a 10 year period from 1993 to 2002 for all cases of food asphyxia/café coronary syndrome. Forty-four cases were identified (M;F=21:23), with one infant (11 mths) and 43 adults (30-96 yrs; mean 68.9 yrs), with a preponderance of victims (57%) aged between 71 and 90 yrs.

Mechanisms of unexpected and/or sudden death in Lafora disease.

A 23-year-old male was found dead wedged between two chairs at his home address. His past history included a diagnosis of Lafora disease (a type of heritable progressive myoclonic epilepsy) at the age of 16 years. This had been characterised by the development of epilepsy and progressive motor impairment and mental deterioration.

The pathological features and circumstances of death of lethal crush/traumatic asphyxia in adults--a 25-year study.

A 25-year retrospective study of cases of crush/traumatic asphyxia autopsied at Forensic Science SA, Adelaide, Australia from 1980 to 2004 was undertaken. A total of 79 cases of crush asphyxia was found consisting of 63 males (80%) and 16 females (20%). The age range of the males was 19-86 years (mean=41.

Ultrastructural changes in the cervical epithelium during the estrous cycle of the marsupial Monodelphis domestica (grey short-tailed opossum).

Ultrastructural changes in the cervical epithelium related to the estrous cycle have been studied in the South American marsupial Monodelphis domestica. The two cervices protrude with prominent papillae into the sinus vaginalis. At times of simple columnar at others of more pseudostratified character consists of two types of cells, ciliated and secretory cells.

Ultrastructural changes in the uterine luminal and glandular epithelium during the oestrous cycle of the marsupial Monodelphis domestica (grey short-tailed opossum).

Ultrastructural changes in the endometrium associated with the oestrous cycle were studied in the South American marsupial Monodelphis domestica. The most conspicuous changes include the height and the differentiation of the uterine luminal and glandular epithelium, which consists of ciliated and non-ciliated cells. The glandular epithelium attains its maximum development during oestrus, the luminal epithelium at postoestrus.
