Drug-facilitated sexual assault followed by femicidal chloroform poisoning and suffocation: A case-report of criminal responsibility.

Introduction: Criminal responsibility evaluation represents one of the most controversial and debated issues in forensic psychiatry. Although clear procedures have been recommended, little research exists on decision-making process by forensic psychiatrists. We present a case assessing the criminal responsibility of a murderer who committed femicide as a result of chloroform poisoning and suffocation after a drug-facilitated sexual assault.

Morpho-functional changes in human tendon tissue.

Insertion tissue biopsies of right arm common extensor tendons from 11 patients with chronic lateral epicondylitis were processed for light and electron microscopy. The subjects were aged between 38 and 54 years (only one was 25). The specimens showed a variety of structural changes such as biochemical and spatial alteration of collagen, hyaline degeneration, loss of tenocytes, fibrocartilage metaplasia, calcifying processes, neovascularization and vessel wall modifications.

Giant cell tumor of tendon sheath: a light and electron microscopic study.

A neoformation has been surgically withdrawn from third finger extensor tendon of the right hand of a 52 year male subject. Light (LM) and electron microscope (EM) observations from a number of tissue fragments allowed the identification of tumor nature, which appeared a giant cell tendon sheath. Moreover, some structural patterns have been described and compared to the previously reported cases.

Calcific chronic lateral epicondylitis: a histological and ultrastructural study.

Fragments of insertion tissue from right arm common extensor muscle have been collected from a 25-year patient with chronic lateral epicondylitis. Specimens, processed for light (LM) and electron (EM) microscopy, evidentiated a variety of degenerative alterations, such as focal hyalinosis, lipoidosis, collagen fiber redistribution, calcifications and vascular changes. Evidence of collagen normal function maintenance and turnover have been also observed in tenocytes.

Early events of liver regeneration in rats: a multiparametric analysis.

5-Bromodeoxyuridine (BrdU), a synthetic analogue of thymidine, has been utilized in vivo to detect the proliferation which occurs in the liver after two-thirds surgical hepatectomy. Immunocytochemical detection of BrdU incorporation has been carried out at both the morphological and flow cytometrical level, while structural changes of regenerating liver have been investigated, using Mallory-Azan-stained paraffin sections, by means of an image analyser. The results obtained show that in vivo DNA synthesis progression throughout S phase follows a pattern similar to that previously described in vitro in both 3T3 fibroblasts and Friend erythroleukemia cells and also demonstrate a precise correlation between morphological patterns of BrdU incorporating cells and their lobular distribution.

Pathology from hydroxyapatite deposits in periarticular tissues. First conclusions on etiopathogenesis.

Biopsies of periarticular tissues from patients with episodes of chronic periarthritis were examinated by histological, ultrastructural and chemico-crystallographic methods. In all samples the mineralogical observations at the optical microscope, showed aggregates of microcrystalline incrustations, whose ultrastructural morphology has been characterized by SEM. The histological observations showed necrosis of collagen fibres and microcrystallization process in cavities and in metaplastic fibrocartilage.

Scanning electron microscopy, chemical and histologic analysis in human periarthritic shoulder biopsy.

In the present study biopsies were analyzed, taken from the left shoulder of a patient who, according to the radiological diagnosis, was suffering from calcific periarthritis. In both optical and electronic microscopy the mineralogical observations showed crystalline aggregations, while the chemical analysis, carried out with an Edax EDS spectrophotometer, confirmed the presence of Ca and P in them, in the ratio typical of biological apatites. The histological observations clearly indicate a change in the metabolism of the tissues present.

Effects of pulsed magnetic fields in the therapy of osteoporosis induced by ovariectomy in the rat.

This paper presents preliminary results on the effects of pulsed electromagnetic fields (EMF) in the therapy of post menopausal osteoporosis induced by ovariectomy in female rats aged ten months. In particular, the effects of the intensity of pulsed EMF applied at constant frequency has been studied. Magnetic fields pulsed at 50 Hz were used having a positive sinusoidal wave form with a maximum intensity of 30 and 70 Gauss.

Morphological aspects of steroid hormone action on rat hepatocyte.

A morphological study was performed on the effect of HC treatment on normal and adrenalectomized rat liver. The observation of liver fragments shows that the hormone treatment can balance only partially the hormonal deficiency caused by ADX, resulting in particular changes of both hepatic architecture and fine ultrastructural organization.

Further observations on pineal brain sand formation and evolution in man.

Acervuli obtained from fragments of the human pineal glands of subjects of both sexes and age ranging from 23 to 87 years were analyzed by light microscopy after histochemical stains and by EDS-microanalysis. It was found that the sub-units and acervuli are positive to P.A.

Bone mineral alterations and Mg content in aging.

The authors propose to determine whether the quantity of bone mass reduction linked to aging is accompanied by qualitative modifications of the mineral structure. To this end, 18 samples of cancellous bone from the femoral heads of two groups of patients (Groups A & B), were examined. Group A was made up of 8 old osteopenic patients suffering from fracture of the femur neck (age 62-84).

A preliminary study of human pineal gland concretions: structural and chemical analysis.

Acervuli and fragments of pineal gland obtained from 33 subjects of both sexes and age ranging from 1 to 87 years, (30 autopsy and 3 biopsy specimens) were analyzed by light microscopy, transmission and scanning electron microscopy, X-ray diffraction and X-ray energy dispersive microanalysis. It was found that primary mineralization occurs in an organic matrix formed by pinealocytes and that hydroxyapatite also takes place in mineral deposition. From our analysis, the formation of acervuli appears to be age and sex independent and can be possibly related to the secretory activity of the gland.

Addiction time and value of Z indicators in Rorschachs of heroin users.

Rorschach test scores for short-term (1 to 3 yr.) and long-term (5 or more yr.) heroin users (ns = 25 each) were compared, to ascertain whether the use of heroin influences the organizational activity, namely, the form level of each response (as measured by Zf and Zd indices).

Histochemical and ultrastructural study of the human pineal gland in the course of aging.

A histochemical and ultrastructural study was carried out on the pineal gland of 2 day- to 86-year-old subjects. Specimens were obtained by stereotaxis in the course of neurosurgery; other specimens were autoptical pineal fragments. Histochemical and ultrastructural analyses showed lipofuscin pigments, frequently localized in the proximity of blood capillaries and of cytoplasmic microacervuli.

Effect of water irrigations on human colonic mucosa structure after sigmoidostomy.

The colonic mucosa of patients with sigmoidostomies, who were operated on for rectal cancer, and treated thereafter for different periods of time with daily water irrigations to obtain complete evacuation, was investigated by histologic and histochemical methods. Microscopic examination of the test specimens showed that the epithelial continuity, the characteristic brush border, and the positive mucous reaction to PAS and Alcian blue-Alcian yellow methods were not significantly changed with respect to controls. In some test specimens a remarkable number of mitoses were evident in the crypts.

[Microscopic research on arachnoid villi in various mammals].

The sagittal sinus in the man, dog, cat and rabbit was studied; we have noted remarkable histological differences within the zoological succession in the system of discharge of the cerebrospinal fluid in the venous system. The differences, probably, are chargeable to the different metabolic encephalic exigences which in the man are exalted and which justify the presence of the more complicated structures.

[Adolescent dyssocial behavior and lack of a father figure during the latency period].

The Authors, taking Andry's hypothesis about the pathogenetic role of the deprivation of father-image during infancy in structuring an inadequate, too rigid or incoherent Super-Ego, assume that could be a possible factor in explaining the social misadaptation of adolescents with prolonged experiences of institutionalisation. The test group, consisted of 163 adolescents and pre-adolescents released from three state institutions in Modena, in the period 1966-1973, it seems to confirm, through the indexes of the socialisation in the family, scholastic and work groups after releases from the institutions, as well as through those of social misadaptation and antisociality, the Author's hypothesis interpreting the social misadaptation as one of the manifestations of the difficulties encountered by adolescents in the adaptation process. These difficulties depend a great deal on a surplus of pathological defenses arising from retarding of the consolidation of the Ego and from developing a negative Ego-Ideal.
