Psychiatric disorders and homicide recidivism

There are no firm epidemiologic data concerning psychiatric disorders associated with homicide recidivism. The authors studied all homicide recidivists who were incarcerated in Finnish prisons or high-security hospitals and had committed their last offense during the 3-year period July 1, 1988-June 30, 1991. All recidivists (13 subjects) could be considered to suffer from either severe alcoholism combined with personality disorder (N = 11, 85%) or from schizophrenia (N = 2, 15%).     

Cerebral palsy following cutting of the nuchal cord before delivery

Five cases identified in the course of medicolegal reviews are described where the umbilical cord wrapped around the neck of the foetus once was cut intentionally, or broken, prior to the extraction of the body. Delivery was delayed on account of shoulder dystocia for a period of time varying from three to seven minutes. All of these infants were born with a low APGAR score. Subsequently, they displayed manifestations of cerebral palsy and two of them also had permanent brachial plexus lesion. This series of incidents indicates that an unexpected arrest of the shoulders may inadvertently compound the problem that the severing of the cord prior to the delivery of the body entails. If, as in the cases presented here, hypoxic brain damage ensues, the severing of the cord may become a suspected causative factor. Our literary review has revealed no reference to severing of the cord having been followed by shoulder dystocia. Along with other instances where similar reviews drew attention to as yet unrecognized clinical phenomena, this unusual cluster of a previously unconsidered type of accident at birth underlines the value of carefully conducted medicolegal reviews as a potential clinical research tool in medicine.

Software for dynamic reconfigurable order picking systems

This paper describes an approach, conceptual framework, and software architecture for dynamic reconfiguration of the order picking system. The research and development project was sponsored by the Material Handling Research Center (MHRC), a National Science Foundation sponsored Cooperative Industry/University Research Center. The storage configuration is assumed to be an in-the-aisle order picking system in which stockkeeping units (SKUs) can occupy variable capacity storage locations and stock-splitting is allowed among zones (clusters). The product mix may include multiple product families with different life cycles, correlated demand within families and commonality of demand across families.

DNA flow cytometric analysis in patients with operable non-small cell lung carcinoma

Fresh surgical specimens of tumors from 60 patients with previously untreated non-small cell lung carcinoma (NSCLC) who underwent radical surgery between January 1991 and October 1992 were investigated by means of flow-cytometry. The nuclear DNA measurement was carried out using a Facscan (Becton, Dickinson, USA). Analysis of the DNA content was performed in all 60 patients whilst cell cycle analysis was possible in 41 cases (68.3%). Forty-two of the 60 cases (70%) were aneuploid and 18 (30%) were diploid. The overall mean value of DNA index was 1.5. Diploid NSCLC were compared with aneuploid tumors: no significant differences in age distribution, sex ratio, histology and staging were found between the two groups (P > 0.05). An S-phase proportion of more than 10% was found in 30 out of 41 patients (73.2%). Early cancer deaths were reported in four patients (6.6%): the aneuploidy rate was very close in these patients (75%) and in the remaining surviving patients (69.6%). An S-phase proportion of more than 10% was found in 100% of early cancer deaths and in 70.2% of the remaining cases; such a difference seems of some importance although it was not statistically significant (P = 0.071). In conclusion, flow-cytometry studies seem to be a useful tool in the understanding of the biological behavior of patients with NSCLC. In the present prospective report there were no significant correlations between DNA measurements and clinical outcome, however, these results suggest that a high S-phase proportion should be seen as a possible prognostic indicator.(ABSTRACT TRUNCATED AT 250 WORDS)     

HIV arthritis

Whether reexposure of varicella-immune persons to varicella-zoster virus would protect against or predispose to development of zoster was analyzed. The rate of zoster in 511 leukemic recipients of varicella vaccine who had 1 or > 1 dose of varicella vaccine and in those who did or did not have a household exposure to varicella was determined. A Kaplan-Meier life-table analysis revealed that the incidence of zoster was lower in those given > 1 dose of vaccine (P < .05). A Cox proportional hazards analysis showed that both household exposure to varicella and receipt of > 1 dose of vaccine were highly protective (P < .01) against zoster. Thus, the risk of zoster is decreased by reexposure to varicella-zoster virus, either by vaccination or by close exposure to varicella.     

Effects of rilmenidine on rats made insulin resistant and hypertensive by a high fructose diet

This study was aimed to determine the effects of rilmenidine, an hypertensive drug, in an animal model of hypertension associated with insulin resistance, i.e. rats fed on a high fructose diet. Wistar rats were fed during four weeks either on a standard diet (S) or on a high fructose diet (F, 34.5% de fructose). In half of the F groups, rilmenidine (1 mg/kg/day) was added to the drinking water during the two last weeks of the diet (FR). Arterial blood pressure as well as insulin efficiency were determined at the end of the four weeks. Body weight gain was higher in F than in S rats (66 +/- 8 g versus 45 +/- 8 g; p < 0.05), this was prevented by rilmenidine treatment (32 +/- 2 g). Arterial systolic blood pressure was increased in F rats (162 +/- 2 vs 155 +/- 2 mmHg; p < 0.05), rilmenidine brought this value back to normal (149 +/- 3 mmHg). During the euglycemic hyperinsulinemic clamp, glucose utilization was lower (10 +/- 1 vs 14 +/- 1.5 mg/min/kg; p < 0.05) and hepatic glucose production higher (1 +/- 0.01 vs 0 mg/min/kg; p < 0.01) in F than in S rats. These changes in insulin action were totally abolished by rilmenidine. These data demonstrate that rilmenidine can ameliorate the deleterious effects of a high fructose diet, i.e. weight gain, hypertension and resistance to the effects of insulin Rilmenidine could represent a potential therapeutic agent for the treatment of hypertension associated with metabolic disorders such as syndrom X and obesity.     

Salvage chemotherapy with mitomycin, vindesine, and cisplatin (MiViP) in recurrent carcinoma of the cervix

We report two cases of metastatic non-functioning pancreatic endocrine tumour with very elevated plasma levels of alpha-fetoprotein. In these two cases, serial plasma levels of alpha-fetoprotein, initially normal, correlated well with hepatic tumour progression and were associated with fatal outcome. These results suggest that elevated plasma concentration of alpha-fetoprotein may be caused by metastatic pancreatic endocrine tumour and than alpha-fetoprotein serial measurement may be useful in prognostic evaluation.
