Gastric mucosa lesions in drowning: its usefulness in forensic pathology.

In a retrospective study of 52 autopsy cases of drowning fatalities, death circumstances, macroscopical and histological findings of the stomach mucosa were carefully studied. Results were compared with a control group, composed by 80 cases of different kinds of asphyxia (hanging, chocking and suffocation), skull injuries, sudden cardiac death and poisonings. The spectrum of gastric lesions observed during autopsy in drowning group, are presented. Stomach mucosa tears were found in 21.1% of the cases of drowning, preferably on fundus (54.5%). The control group does not show similar lesions. The physiopathological mechanism of its production, are also discussed. On sight of these results, it is concluded that the macro and microscopical examination of the stomach could be useful as an adjunct procedure for drowning diagnosis. The presence of gastric mucosa lesions has an intravital significance and could be correlated with other anatomical or histological signs of drowning for the diagnosis. In every case, necropsic examination must be carried out as soon as possible in order to avoid putrefactive artifacts.

Left aortic arch with right-sided descending aorta associated with sudden neonatal death: a case report.

We present the case of a 26-day-old female in whom left aortic arch with right-sided descending aorta occurred. The previously healthy newborn baby was found dead on her bed. This anomaly is very uncommon and its clinical presentation as sudden death is also exceptional with only a few cases having been reported in the literature. The pathological findings and embryological origins of this malformation, so-called 'circumflex aorta' are discussed. The pertinent literature is reviewed.

Delayed presentation of carotid dissection, cerebral ischemia, and infarction following blunt trauma: two cases.

Carotid artery dissection followed by cerebral infarction as a result of blunt trauma can occur in a number of forensically relevant situations. We describe two such cases. In the first case, a 19-year-old female was involved in a road traffic accident, when her car crashed into the rear of another car. Initially, the young woman presented a minor head injury without loss of consciousness and minor bruising to the left side of the neck. After 48 h, she had developed confusion, speech difficulties, right facial nerve paralysis, and right hemiplegia. CT scan and carotid angiography showed cerebral ischemia with infarction in the territory of the middle left cerebral artery and complete dissection of the left carotid artery. In the second case, a 33-year-old male with depression attempted to hang himself. The rope gave way and he fell down. He had also taken a paracetamol, and a non-steroidal anti-inflammatory drug overdose. He did not lose consciousness but appeared withdrawn and depressed. Approximately 6 h later, his conscious state deteriorated. A CT scan revealed thrombosis of the left internal carotid artery, extending to the middle cerebral artery. The patient died. Both cases reinforce the need for full neurological assessment and review of any individual subject to blunt trauma to the neck, whether accidental or deliberate or where the history is incomplete. In the forensic setting, in particular, RTAs, suspension by the neck, strangulation, and garotting are all instances when examination and assessment must be thorough--and clear advice given--in the absence of any immediate signs or symptoms--that any new symptoms or signs require immediate and thorough neurological investigation. There should be low threshold for prolonged neurological observation or further neurovascular investigations such as ultrasound, CT or MRI scan or angiography, to minimize the risk of developing potentially fatal or incapacitating sequelae.

Allele frequency distribution of the STR loci HUMTPOX, HUMTH01 and HUMVWA in Asturias (north Spain).

In order to use genetic loci in forensic identity testing, some population data are needed. This paper presents a report of allele frequency data for the loci HUMTH01, HUMTPOX and HUMVWA in a population sample from Northern Spain. No deviation from the Hardy-Weinberg equilibrium was detected in any of the three markers investigated and there was no evidence of association between the alleles of these loci. Statistical analysis was also carried out to obtain some parameters of medicolegal interest and comparative studies were carried out with other populations studied to date for these five loci. The Asturian sample does not differ substantially from other Caucasian and Spanish populations.

Characteristics of a population undergoing treatment for drug addiction in a therapeutic community setting in Spain.

The authors discuss the findings of a study of the personal history characteristics of a population of 223 individuals who underwent treatment for drug addiction at the Masma Therapeutic Community, Lugo, Spain, during the period September 1984 to March 1986. The population consisted of 58 females and 165 males, predominantly from middle-class backgrounds. Nearly all were multiple drug abusers, cannabis and heroin being the most widely abused drugs. Over half the population received treatment prior to admission to the Masma Community for the abuse of either barbiturates or opiates. The research instrument used was a self-report questionnaire, completed by participants anonymously and on a voluntary basis. It included items relating to personal and family background, aspects of drug abuse and type of prior treatment.

[Suicide in the elderly].

Being the suicide a conduct very old, it's at present a problem with the epidemic characteristics and it's for this question that it has aroused a great interest. But, we have observed that the interest is only about the suicide youngest persons. They are little the factors and tendencies suicides studies in years old persons ("third age"), though also the suicide in years old persons is augmenting. We have analyzed 74 suicides in greater 60 years old persons occurred in our community. We have studied several epidemiological factors: sex, age, civil condition, the suicide mechanism, place where it's occurred, hour, day, month, the pathological antecedents and the other case antecedents.

[Prison psychosis: apropos of a case].

We have realized a review and actualization of prisons psychosis; an important problem at present in prison's ambit because it generates a great number of recoveries and graves questions to prison's doctors and psychiatry's doctor which they work in this world. Also, this problem origins a numbers judicial's questions in relation with the imputability. Further, we expose a clinic case of our practice.

Drug use among adolescents in Asturias (Spain).

A survey of drug use, based on a sample of 2,537 school students in the 15-17 year age group selected from 11 schools in central Asturias (Spain), showed that 697 respondents, or 29.1 per cent, were drug users. Cannabis was the most widely abused drug: 500 respondents, or 20.8 per cent of the total sample, became involved with this drug at some time in their lives. The percentages of the total sample show that the use of cannabis at any time ("ever" use) was followed by use of: tranquillizers (10.3 per cent), amphetamines and amphetamine-like substances (7.9 per cent), inhalants (2.3 per cent), hallucinogens (2.0 per cent), sedatives (1.7 per cent), opiates (1.4 per cent) and cocaine (1.2 per cent). Males were generally more involved with drugs than females were. The average age at first drug use was 15.4 for males and 15.5 for females.

[Epidemiologic differences in delinquents relative to their psychiatric records].

We report the results of a survey carried out by us in the penitentiary from 1989 to 1992. The aim of it was to determine a possible relationship between criminal behaviour and previous psychiatric pathology. A total of 121 individuals imprisoned from February to april 1989 were studied. Only those convicts who had been free taken into account. Individuals who had been imprisoned before in other prisons were not included in our study. A questionnaire was elaborated by us to carry out this survey. The convicts were tested as soon ad they came into the Oviedo penitentiary. The convicts were classified within two groups. In the first group only those who had previous psychiatric pathology were included. The rest of them, including drug addicts were part of the second group of our study. Our results show that criminal behaviour is much common between those who do not have suffered previously from psychiatric pathology. Furthermore, relationship between psychiatric pathology of the convict and his mother's criminal behaviour was proven. It aslo was shown between psychiatric pathology and suicide or own-inflected injuries.
