Off-label indications for atypical antipsychotics: A systematic review

INTRODUCTION: With the introduction of newer atypical antipsychotic agents, a question emerged, concerning their use as complementary pharmacotherapy or even as monotherapy in mental disorders other than psychosis. MATERIAL AND METHOD: MEDLINE was searched with the combination of each one of the key words: risperidone, olanzapine and quetiapine with key words that refered to every DSM-IV diagnosis other than schizophrenia and other psychotic disorders, bipolar disorder and dementia and memory disorders. All papers were scored on the basis of the JADAD index. RESULTS: The search returned 483 papers. The selection process restricted the sample to 59 papers concerning Risperidone, 37 concerning Olanzapine and 4 concerning Quetiapine (100 in total). Ten papers (7 concerning Risperidone and 3 concerning Olanzapine) had JADAD index above 2. Data suggest that further research would be of value concerning the use of risperidone in the treatment of refractory OCD, Pervasive Developmental disorder, stuttering and Tourette's syndrome, and the use of olanzapine for the treatment of refractory depression and borderline personality disorder. DISCUSSION: Data on the off-label usefulness of newer atypical antipsychotics are limited, but positive cues suggest that further research may provide with sufficient hard data to warrant the use of these agents in a broad spectrum of psychiatric disorders, either as monotherapy, or as an augmentation strategy.     

Endogenous opiates: 1980

Vast amounts of research have been done that have attempted to delineate the pharmacological and physiological effects of the endogenous opiate peptides. A great deal of knowledge has also been accumulated in a limited time span concerning the types and locations of the opiate receptors and peptides, as well as their functions. In 1980, reports were made concerning the effects of these peptides on analgesia, on tolerance and dependence, on activity, on learning and memory, on schizophrenia and other types of emotional disturbances, and on physiological responses such as eating and drinking, cardiovascular responses, and sexual function. Additional understanding was also gained concerning their interactions with neurotransmitters, other neuropeptides, and hormones. These and other studies published only in 1980 are reviewed in this paper, which is the third of an annual series.     

Activities of the nuclear envelope in the salivary glands of Drosophila

Morphological data are presented concerning the single-membrane-bound vesicles ("oval bodies") associated with the nuclear envelopes of larval salivary gland cells of Drosophila. Data are also presented concerning the existence of cytoplasmic annulate lamellae in these same cells. The mode of formation of these structures, as well as the relationships between them and with other cytoplasmic organelles are described. The possible functional significance of these phenomena is discussed.     

DNA strand breaks in pancreatic islets by in vivo administration of alloxan or streptozotocin

Administration of diabetogenic doses of alloxan or streptozotocin to rats caused extensive DNA strand breaks in pancreatic islets. DNA of pancreatic exocrine cells was not affected by either alloxan or streptozotocin. hepatocyte DNA was fragmented by streptozotocin but not by alloxan. Intracellular NAD level was decreased in tissues whose DNA was fragmented. The results may raise a novel aspect concerning the mechanisms of action of the diabetogenic agents as well as concerning the organotropisms of the agents.     

Immunobiological properties of Yersinia pestis antigens

The present review contains information concerning immunobiological properties of plague microbe antigens. All of the identified antigens are evaluated in relation to pathogenicity of Yersinia pestis namely a resistance to phagocytosis, toxicity, adhesiveness etc. as well as persistence ability and adaptation to variable environment. In addition, the role of antigens in immunogenicity of living plague microbe for experimental animals is considered. The data concerning mechanisms of antigenic contribution to the development of adaptive immunity are presented.     

The effects of rate variation on ancestral inference in the coalescent

We describe a Markov chain Monte Carlo approach for assessing the role of site-to-site rate variation in the analysis of within-population samples of DNA sequences using the coalescent. Our framework is a Bayesian one. We discuss methods for assessing the goodness-of-fit of these models, as well as problems concerning the separate estimation of effective population size and mutation rate. Using a mitochondrial data set for illustration, we show that ancestral inference concerning coalescence times can be dramatically affected if rate variation is ignored.     

Subjects of Speculation: Emergent Life Sciences and Market Logics in the United States and India

This article traces systems of exchange concerning the life sciences and capital and how they configure subjectivity in the United States and India. This is done through case studies concerning the emergence of personalized medicine in the two locales. In the U.S. case, I argue for the configuration of the subjects of personalized medicine as sovereign consumers; in the Indian case, I argue for their configuration as experimental subjects. I situate these arguments in the context of epistemologies of genomics and the consolidation of systems of speculative capitalism.     

Fatty acid levels in blood of cyclostomes and fish

Synopsis Experimental data obtained on cyclostomes and fish concerning the levels of plasma fatty acids (PFA), their biological role as an energetic substrate, various factors affecting PFA and mechanisms involved in the control of their level are reviewed.It was shown that PFA levels in lamprey and fish depend strongly on season, circadian rhythm, nutritional state, age, sex, intrinsic activity of individuals and are regulated by some metabolites as well as hormones. The question concerning the nervous control of PFA in cyclostomes and fish needs further elucidation on account of scarce information available at present.     

Genetic counseling in balanced chromosomal inversions

The genetic counseling given at carriers of equilibrated chromosomal inversions is in relation with the type of the inversion. The risk for carriers of pericentric inversions concerning euchromatic regions depends on many factors, i.e. the length of the inserted segment in relation with the total length of the chromosome involved, the sex of the carrier and the way of assortment. In contrast, the carriers of pericentric inversions concerning the heterochromatic regions, as well as of paracentric inversions, have not a particular risk for their descendance.     

Contribution of trigeminal and facial reflexes to the localization of Vth, VIIth, and VIIIth cranial nerve dysfunction.

After a review of electrophysiological studies in 1,500 cases concerning different types of lesions of the trigeminal nerve, the acousticofacial complex, and the brain stem, one can conclude that beside the intensive clinical examination which most often allows a precise topographic diagnosis, study of trigeminofacial and facial reflexes appears to be an essential diagnostic method to determine the topography of the lesions. On the other hand, this study can sometimes contribute to the prognostic evaluation as well as the choice of the approach in some lesions concerning the acousticofacial complex.     

An Uncertain Dominion: Irish Psychiatry,Methadone, and the Treatment of Opiate Abuse

This paper investigates some productive ambiguities around the medical administration of methadone in the Republic of Ireland. The tensions surrounding methadone maintenance therapy (MMT) are outlined, as well as the sociohistorical context in which a serious heroin addiction problem in Ireland developed. Irish psychiatry intervened in this situation, during a time of institutional change, debates concerning the nature of addiction, moral panics concerning heroin addiction in Irish society and the recent boom in the Irish economy, known popularly as the Celtic Tiger. A particular history of this sort illuminates how technologies like MMT become cosmopolitan, settling into, while changing, local contexts.     

Tendencies in auditory physiology

Main tendencies in studying of human and animals auditory system with psychoacoustical and electrophysiologycal methods are considered. Concerning psychoacoustical studies some basic data are presented as well as contemporary tendencies in hearing physiology in analysis of the intensity, frequency, temporal characteristics of the sound signals and data related to such phenomena as masking and adaptation. Data concerning directional hearing are presented in detail as a basis of auditory virtual reality. In electrophysiological studies of the auditory system detailed analysis of mapping in auditory centers and mechanisms concerning localization of unmoved and moving auditory stimuli was performed. Special attempt was paid to consider the reflection of different types of auditory signals in human evoked potentials.     

Man-made trace fossils on bones

The different types of ancient man-made bone modifications serve as evidence concerning human activities. Correct identification and interpretation of cut, scrape, chop, sawing, and blow marks is based on their morphology and recurrent position on the various bones. Important information concerning the processes by which the marks were inflicted leads to a greatly improved insight into modes of fundamental human activities such as hunting, killing, skinning, butchering, food preparation, and marrow fracturing.     

Support and conflict of kinsmen in Norse Earldoms,Icelandic families,and the English royalty

Data concerning the Norse Earls of the Orkney Islands, Icelandic families, and the conflicts concerning the sovereignty of England are presented. The data suggest that support vs conflict with kin is influenced by degree of biological relatedness but also by the needs for support by kinsmen, as influenced by the ability to hire retainers, and by the costs and benefits of support vs conflict.     

Oxygen reduction in chloroplasts and the ascorbate cycle

Current views concerning the generation of superoxide radicals and hydrogen peroxide in chloroplasts as well as their toxic influences on photosynthesis are presented. Systems of H2O2 detoxification including the ascorbate peroxidase reactions and the ascorbate regenerating reactions are described. Data concerning mechanisms of monodehydroascorbate reduction by the photosynthetic electron transport chain are reviewed. The participation of the Mehler-peroxidase reaction in building of a proton gradient across the thylakoid membrane and its possible input in ATP synthesis and in protection from photoinhibition are analyzed. Ascorbate functions in chloroplasts and the need to consider the high concentration of ascorbate in chloroplasts when photosynthetic reactions in vivo are discussed are briefly reviewed.     

The complexity of anti-estrogen responses

The actions and biological responses of anti-estrogens are a function of: the experimental conditions, the parameters, the organ and the animal species considered. Target tissues for estrogens in the guinea-pig during the perinatal period are interesting models to explore the action of anti-estrogens. The summary of the data indicates: (1) In the fetal uterus of guinea-pig in in vivo experiments (after injection to the maternal compartment) tamoxifen acts as a real agonist concerning growth, as a partial agonist concerning the stimulation of the progesterone receptor. (2) In in vitro experiments (in organ culture of fetal uterus or in isolated cells) anti-estrogens (tamoxifen or 4-hydroxy-tamoxifen) act as antagonists and also inhibit the effects provoked by estrogens. (3) In the uterus and vagina of newborn guinea-pigs, tamoxifen and its derivatives: 4-hydroxytamoxifen and N-desmethyltamoxifen act as real agonists concerning the uterotrophic and vaginotrophic effects, and also stimulate the amount of DNA per organ, but concerning the progesterone receptor in the uterus, in the short treatment anti-estrogens act as partial agonists but they have no effect in the long treatment. In the vagina in the short treatment anti-estrogens provoke no significant effects, but in the long treatment they are full agonists. In neither of the two biological responses studied (growth and progesterone receptor) does tamoxifen and its derivatives block the action of estradiol. (4) The use of a monoclonal antibody to the estrogen receptor revealed quantitative differences in the activation of the estrogen receptor when bound to estradiol or tamoxifen. This observation was in agreement with the lesser extent of binding to DNA-cellulose of the tamoxifen-estrogen receptor complex as compared with the estradiol-estrogen receptor complex. This fact suggests an impaired activation of the estrogen receptor induced by tamoxifen which might be related to the different biological responses provoked by estrogens and anti-estrogens.     

Effect of weak alternating ultra-low frequency magnetic fields on the development of the hypercoagulation syndrome in immobilized rats

The experimental results are given concerning the effect of variable magnetic field (VMF) with the frequency of 8 Hz and intensity 4 A/m on some parameters of rat haemocoagulation system under standard mobile regime as well as under prolonged hypokinesia. It is stated that repeated daily exposition of VMF causes hypocoagulational blood shift in intact animals. Under the effect of simultaneous VMF and hypokinesia the correction of hypercoagulational shift induced by animal hypokinesia was detected. The highest VMF effect was observed in prolonged experiments. A conclusion is drawn concerning the ability of VMF with the given parameters to limit the development of rat blood hypercoagulation under hypokinesia.     

Radiosensitivity of somatic cells and imaginal disks of male and female Drosohila]

Primary chromosome damages as well as the frequency of spontaneous and X-rays induced chromosome aberrations in Drosophila melanogaster males and females are studied. It is found using cytofluorimetric method that primary chromosome damages in ganglia cells of females and males are the same. In these cells as well as in cells of imaginal discs the frequency of induced chromosome aberrations, except gaps, is considerably higher for females. Ganglia cells of females and males of Drosophila are found not to differ from each other in their proliferation activity. The frequency of morphoses for both sexes is also the same. The assumption is made concerning the role of the non-identical repair in the increased mutability of female somatic cells, which is more intensive in this sex, as well as concerning more intensive identical repair in imaginal discs of females.
