OBJECTIVE: In spite of the richness of the Brazilian biodiversity, no phytomedicines have been developed from this flora with the purpose of being used in psychiatric treatments. The objective of the present study was to document the use of plants with possible psychoactive effects in rituals performed by the Krahô Indians, who live in the cerrado savannahs biome in the central region of Brazil. Also, the present data were compared with the data obtained during a review of the literature on the use of psychoactive plants by 25 Brazilian indigenous groups. METHOD: The study was carried out during two years of fieldwork during which anthropological and botanical methods were employed. RESULTS: Seven local shamans were interviewed and they indicated 98 formulas, consisting of 45 plant species that appear to have psychoactive properties and were used in 25 different treatments. Some of the psychoactive properties were "prevention of madness", "stimulant effect", "tranquilizing effect", "prevention of tremors", "longer sleeping period", "open mind" and "induction of sleep". This article also describes the review of literature, which recorded 58 plants that may have psychoactive effects used by 25 Brazilian Indian cultures. CONCLUSION: The treatment of psychological/psychiatric disorders based on the plants used by the Krahô Indians is very rich. It is also observed among other Brazilian indigenous groups. Future phytochemical and pharmacological studies on these plants may develop new medicines to treat psychiatric disorders.

Psychoactive plants contain chemicals that presumably evolved as allelochemicals but target certain neuronal receptors when consumed by humans, altering perception, emotion and cognition. These plants have been used since ancient times as medicines and in the context of religious rituals for their various psychoactive effects (e.g., as hallucinogens, stimulants, sedatives). The ubiquity of psychoactive plants in various cultures motivates investigation of the commonalities among these plants, in which a phylogenetic framework may be insightful. A phylogeny of culturally diverse psychoactive plant taxa was constructed with their psychotropic effects and affected neurotransmitter systems mapped on the phylogeny. The phylogenetic distribution shows multiple evolutionary origins of psychoactive families. The plant families Myristicaceae (e.g., nutmeg), Papaveraceae (opium poppy), Cactaceae (peyote), Convolvulaceae (morning glory), Solanaceae (tobacco), Lamiaceae (mints), Apocynaceae (dogbane) have a disproportionate number of psychoactive genera with various indigenous groups using geographically disparate members of these plant families for the same psychoactive effect, an example of cultural convergence. Pharmacological traits related to hallucinogenic and sedative potential are phylogenetically conserved within families. Unrelated families that exert similar psychoactive effects also modulate similar neurotransmitter systems (i.e., mechanistic convergence). However, pharmacological mechanisms for stimulant effects were varied even within families suggesting that stimulant chemicals may be more evolutionarily labile than those associated with hallucinogenic and sedative effects. Chemically similar psychoactive chemicals may also exist in phylogenetically unrelated lineages, suggesting convergent evolution or differential gene regulation of a common metabolic pathway. Our study has shown that phylogenetic analysis of traditionally used psychoactive plants suggests multiple ethnobotanical origins and widespread human dependence on these plants, motivating pharmacological investigation into their potential as modern therapeutics for various neurological disorders.

Two clinical cases of meconium peritonitis in the fetuses are presented. The diagnosis was made prenatally at 30+5 and 20+1 weeks of gestation. The main ultrasound signs were ascites, loop expansion and thickening of the intestinal wall, peritoneal calcifications, meconium pseudocysts. In one case, pregnancy was complicated by polyhydramnios. In both cases, the pregnancy ended in premature birth, followed by surgical treatment during the first days of life. A review of the literature on the topic are discussed the etiology, the spectrum and frequency of ultrasound signs suggesting this condition in the fetus, the effectiveness of prenatal diagnosis, the prognosis for the life and health of the newborn, as well as the impact of the quality and timeliness of the prenatal diagnosis on the management of pregnancy and timeliness of surgical care for the newborn.

<b><i>Background:</i></b> Arteriovenous malformations (AVMs) of the brain and face present unique challenges for clinicians. Cerebral AVMs may induce hemorrhage or form aneurysms, while facial AVMs can cause significant disfigurement and pain. Moreover, facial AVMs often draw blood supply from arteries providing critical blood flow to other important structures of the head which may make them impossible to treat curatively. Medical adjuvants may be an important consideration in the management of these patients. <b><i>Summary:</i></b> We conducted a systematic review of the literature to identify other instances of molecular target of rapamycin (mTOR) inhibitors used as medical adjuvants for the treatment of cranial and facial AVMs. We also present 2 cases from our own institution where patients were treated with partial embolization, followed by adjuvant therapy with rapamycin. After screening a total of 75 articles, 7 were identified which described use of rapamycin in the treatment of inoperable cranial or facial AVM. In total, 21 cases were reviewed. The median treatment duration was 12 months (3–24.5 months), and the highest recorded dose was 3.5 mg/m<sup>2</sup>. 76.2% of patients demonstrated at least a partial response to rapamycin therapy. In 2 patients treated at our institution, symptomatic and radiographic improvement were noted 6 months after initiation of therapy. <b><i>Key Messages:</i></b> Early results have been encouraging in a small number of patients with inoperable AVM of the head and face treated with mTOR inhibitors. Further study of medical adjuvants such as rapamycin may be worthwhile.

The paper explores the factors that affect proximal and distal employability behavior within the employer satisfaction perspective a vis recruitment of the fresh management graduates. The study undertakes a comprehensive review of the literature and categories the literature as divided across three broad streams: individual preparedness, institutional support mechanisms and organization support to career enhancement. The ‘determinants’ of employer satisfaction in recruiting the fresh management post graduates and their effective operationalization is indeed challenging. The paper attempts to explore and bring together the divergent pieces of literature under the proximal and distal perspectives as shaping ‘employability’ prospects.

BackgroundPrevious reports have suggested an increased prevalence of minor physical anomalies (MPAs) in schizophrenia.MethodA review of the literature was performed to examine the relationship between MPAs, schizophrenia and other disorders.ResultsPrevious studies demonstrate a number of methodological shortcomings. Moreover, MPAs are found in several other psychiatric disorders. Proponents of the neurodevelopmental model of schizophrenia have focused on an environmental explanation for the increased prevalence of MPAs. We argue that this may be overly simplistic and propose various ways in which genetic factors may also be involved.ConclusionsBetter studies should be performed to examine more precisely the nature of MPAs in schizophrenia and other disorders and also the relationship between MPAs and other developmental abnormalities. At present, it is unclear if MPAs are directly related to the pathogenesis of the disorder or even if they are related to the timing of critical events.

AbstractInternet addiction is a newly emergent disorder. It has been found to be associated with a variety of psychiatric disorders. Information about such coexisting psychiatric disorders is essential to understand the mechanism of Internet addiction. In this review, we have recruited articles mentioning coexisting psychiatric disorders of Internet addiction from the PubMed database as at November 3, 2009. We describe the updated results for such disorders of Internet addiction, which include substance use disorder, attention-deficit hyperactivity disorder, depression, hostility, and social anxiety disorder. We also provide discussion for possible mechanisms accounting for the coexistence of psychiatric disorders and Internet addiction. The review might suggest that combined psychiatric disorders mentioned above should be evaluated and treated to prevent their deteriorating effect on the prognosis of Internet addiction. On the other hand, Internet addiction should be paid more attention to when treating people with these coexisting psychiatric disorders of Internet addiction. Additionally, we also suggest future necessary research directions that could provide further important information for the understanding of this issue.
