Evaluation of severe hypoglycemia and common mental disorders in patients receiving insulin analogues for treatment of type 1 diabetes

ABSTRACT This is a retrospective report of the frequency of severe hypoglycemia and the association between common mental disorders and type 1 diabetes mellitus treated with insulin analogues. Patients with severe hypoglycemia compared with those without this complication had a higher prevalence of positive screening for common mental disorders (88% vs.77%, respectively, p = 0.03).

Post-finasteride syndrome

Abstract Finasteride is a 5α-reductase enzyme inhibitor that has been approved for the treatment of male androgenic alopecia since 1997. Over time, it has been considered a safe and well-tolerated drug with rare and reversible side effects. Recently there have been reports of adverse drug-related reactions that persisted for at least three months after discontinuation of this drug, and the term post-finasteride syndrome arose. It includes persistent sexual, neuropsychiatric, and physical symptoms. Studies to date cannot refute or confirm this syndrome as a nosological entity. If it actually exists, it seems to occur in susceptible people, even if exposed to small doses and for short periods, and symptoms may persist for long periods. Based on currently available data, the use of 5α-reductase inhibitors in patients with a history of depression, sexual dysfunction, or infertility should be carefully and individually assessed.

Preventive effects of Topiramate on methylphenidate induced behavioral disorders / Efectos preventivos de topiramato en los trastornos del comportamiento inducidos por metilfenidato

Neuronal cell damage is often caused by prolonged misuse of Methylphenidate (MPH). Topiramate (TPM) carries neuroprotective properties but its assumed mechanism remains unclear. The present study evaluates in vivo role of various doses of TPM and its mechanism against MPH-induced motor activity and related behavior disorder. Thus, we used domoic acid (DOM), bicuculline (BIC), Ketamine (KET), Yohimibine (YOH) and Haloperidole (HAL) as AMPA/kainite, GABAA, NMDA, ɑ2 adrenergic and D2 of dopamine receptor antagonists respectively. Open Field Test (OFT), Elevated Plus Maze (EPM) and Forced Swim Test (FST) were used to study motor activity, anxiety and depression level. TPM (100 and 120 mg/kg) reduced MPH-induced rise and inhibited MPH-induced promotion in motor activity disturbance, anxiety and depression. Pretreatment of animals with KET, HAL, YOH and BIC inhibited TPM- improves anxiety and depression through the interacting with Dopaminergic, GABAA, NMDA and ɑ2-adrenergic receptors.

El daño a las células neuronales a menudo es causado por el uso prolongado de metilfenidato (MPH). El topiramato (TPM) tiene propiedades neuroprotectoras, pero su mecanismo de acción no es claro. El presente estudio evalúa el papel in vivo de varias dosis de TPM y su mecanismo contra la actividad motora inducida por MPH y el trastorno de comportamiento relacionado. Utilizamos ácido domoico (DOM), bicuculina (BIC), ketamina (KET), yohimbina (YOH) y haloperidol (HAL), así como antagonistas AMPA/kainato, GABAA, NMDA, ɑ2-adrenérgico y D2 dopaminérgicos, respectivamente. Se utilizaron las pruebas de campo abierto (OFT), elevación de laberinto (EPM) y natación forzada (FST) para estudiar la actividad motora, la ansiedad y el nivel de depresión. El TPM (100 y 120 mg/kg) redujo el aumento inducido por MPH e inhibió la promoción inducida por MPH en la alteración de la actividad motora, la ansiedad y la depresión. El tratamiento previo de animales con KET, HAL, YOH y BIC inhibió el TPM, mejora la ansiedad y la depresión a través de la interacción con los receptores dopaminérgicos, GABAA, NMDA y ɑ2-adrenérgico.

Uso e abuso de benzodiazepínicos na atenção primária à saúde: práticas profissionais no Brasil e em Cuba / Use and abuse of benzodiazepines in primary healthcare: professional practices in Brazil and Cuba / Uso y abuso de benzodiacepinas en la atención primaria de salud: prácticas profesionales en Brasil y Cuba

O presente estudo buscou compreender aspectos assistenciais presentes na base da utilização indiscriminada de benzodiazepínicos. Com base numa parceria entre uma universidade brasileira e uma cubana, buscou-se o entendimento das práticas relacionadas ao uso desses medicamentos na atenção primária e dos sentidos que profissionais de saúde atribuem a elas. A investigação integrou um estudo de casos múltiplos realizado nos municípios de São Paulo e Diadema (Brasil) e Santiago de Cuba (Cuba). O trabalho de campo adotou como estratégias de coleta de dados entrevistas individuais e grupos focais. Os dados, analisados tematicamente, revelaram cinco temas: (i) terra de ninguém: a ausência de gestão sobre o uso dos benzodiazepínicos pelos profissionais da atenção básica; (ii) indicação inadequada: o benzodiazepínico prescrito psra situações injustificáveis; (iii) salvação e perdição: o medicamento como atenuante da dificuldade de atuação na saúde mental pelos profissionais da atenção primária; (iv) pouco empoderamento dos profissionais da atenção primária para atuação na saúde mental; e (v) cuidado fragmentado: a desarticulação da rede de atenção psicossocial. A pouca apropriação das questões da saúde mental pelos profissionais da atenção primária, a fragmentação do cuidado, a sobrecarga de trabalho com temas considerados prioritários, as deficiências na disponibilidade de recursos terapêuticos e o pouco investimento em formação específica contribuem para o uso não adequado de benzodiazepínicos. Independentemente dos contextos sanitários estudados, os desafios são semelhantes para os sistemas de saúde e só podem ser enfrentados se convertidos em prioridade para a gestão das organizações e para o conjunto dos profissionais.

The current study aimed to grasp the healthcare aspects present at the basis of the indiscriminate use of benzodiazepines. Based on a partnership between a Brazilian university and a Cuban university, the study aimed to understand the practices related to the use of these drugs in primary care and the meanings healthcare workers assign to them. The research was part of a multiple case study in the cities of São Paulo and Diadema (Brasil), and Santiago de Cuba (Cuba). The fieldwork data collection strategy was based on individual interviews and focus groups. Data were analyzed thematically and yielded five themes: (i) no man's land: lack of management of benzodiazepine use by primary care workers; (ii) inadequate indications: the benzodiazepine prescribed for unjustifiable situations; (iii) salvation and perdition: the medicine as attenuating the difficulty of acting in mental health by primary care professionals; (iv) limited empowerment to work in mental health; and (v) fragmented care: dissociation of the psychosocial care network. Limited grasp of mental health issues by primary care workers, fragmented care, work overload with what are considered other priorities, deficiencies in the availability of therapeutic resources, and limited investment in specific training contribute to the inadequate use of benzodiazepines. Independently of the health contexts, the challenges are similar for the health systems and can only be confronted if they become a priority for the organizations' management and the health workers as a whole.

La investigación integró un estudio de casos múltiples, realizado en los municipios de Sao Paulo y Diadema (Brasil) y Santiago de Cuba (Cuba). El trabajo de campo adoptó como estrategias de recogida de datos entrevistas individuales y grupos focales. Los datos, analizados temáticamente, revelaron cinco temas que detallamos a continuación. (i) tierra de nadie: la ausencia de gestión sobre el uso de las benzodiacepinas por parte de los profesionales de la atención básica; (ii) indicación inadecuada: las benzodiacepinas para situaciones injustificables; (iii) salvación y perdición: la medicación como atenuación de la dificultad de actuar en la salud mental por los profesionales de la atención primaria; (iv) poco empoderamiento para trabajar en el ámbito de la salud mental y (v) cuidado fragmentado: la desarticulación de la red de atención psicosocial. La escasa asunción de las cuestiones de salud mental por parte de los profesionales de atención primaria, la fragmentación del cuidado, la sobrecarga de trabajo con temas considerados prioritarios, las deficiencias en la disponibilidad de recursos terapéuticos y la poca inversión en formación específica contribuyen al uso no adecuado de benzodiacepinas. Independientemente de los contextos sanitarios estudiados, los desafíos son semejantes en todos los sistemas de salud y sólo pueden enfrentarse si se convierten en prioridad para quienes gestionan instituciones, así como para el conjunto de profesionales.

Compensation for Occupational Neurological and Mental Disorders

Standards for the recognition of occupational diseases (ODs) in Korea were established in 1954 and have been amended several times. In 2013, there was a significant change in these standards. On the basis of scientific evidence and causality, the International Labour Organization list, European Commission schedule, and compensated cases in Korea were reviewed to revise the previous standards for the recognition of ODs in Korea. A disease-based approach using the International Classification of Diseases (10th version) was added on the previous standards, which were agent-specific approaches. The amended compensable occupational neurological disorders and occupational mental disorders (OMDs) in Korea are acute and chronic central nervous system (CNS) disorders, toxic neuropathy, peripheral neuropathy, manganese-related disorders, and post-traumatic stress disorder. Several agents including trichloroethylene (TCE), benzene, vinyl chloride, organotin, methyl bromide, and carbon monoxide (CO) were newly included as acute CNS disorders. TCE, lead, and mercury were newly included as chronic CNS disorders. Mercury, TCE, methyl n-butyl ketone, acrylamide, and arsenic were newly included in peripheral neuropathy. Post-traumatic stress disorders were newly included as the first OMD. This amendment makes the standard more comprehensive and practical. However, this amendment does not perfectly reflect the recent scientific progress and social concerns. Ongoing effort, research, and expert consensus are needed to improve the standard.

[ comparative study on the personality traits of opioid- dependents with and without somatic chronic pain complaints]

Some people use opioid substances to relief their chronic somatic pains. There are differences in the personality traits of this individuals and others who abuse opioid substances. The purpose of the present study was to compare these two groups in regard to their personality traits and disorders. In a cross-sectional study between 2007 to 2011, all patients referred for drug quit to the outpatient addiction clinic of Imam Hospital affiliated to Jundishapur University were investigated demographically. In addition, all of them underwent physical examination, MMPI test and psychiatric interview. Then they were divided into two groups of "with pain complaint" and "without pain complaint". Their personality traits were compared using t-test and chi[2]. The total number of patients was 488, including 478 males and 10 females. Mean scores of Psychatenia [pt] and paranoia [Pa] indexes in the patients who suffered from chronic non- cancer pain was lower in comparison to the patients without pain complaint. Based on the results of psychological interview, the prevalence of personality disorder was higher in the "without pain" group. Patients with chronic pain had higher educational degrees and they were more likely under the influence of their friends at the onset of opioid abuse. In the present study those who used opioid for pain relief, had healthier psychiatric profiles and personalities. Their psychiatric interviews were more valid and reliable and their psychological problems were less than the other group and their addiction was a maladaptive behavior

Advances in research of ketamine addiction mechanism / 法医学杂志

Ketamine is a phencyclidine derivative acting primarily as a noncompetitive antagonist of N-methyl-D-aspartate (NMDA) excitatory glutamate receptors. As a common intravenous anaesthetic in clinic, it is also increasingly abused because of its hallucination and addiction effects. Based on the pharmacological and toxicologic characteristics of ketamine and the acknowledged addiction mechanism of other abused drugs, this article reviews the possible addiction mechanism of the ketamine in the aspects of its enhanced effects and reward systems, the anatomic structures, the related receptors and the individual differences.

Cannabidiol: from an inactive cannabinoid to a drug with wide spectrum of action / Canabidiol: de um canabinóide inativo a uma droga com amplo espectro de ação

OBJECTIVE: The aim of this review is to describe the historical development of research on cannabidiol. METHOD: This review was carried out on reports drawn from Medline, Web of Science and SciELO. DISCUSSION: After the elucidation of the chemical structure of cannabidiol in 1963, the initial studies showed that cannabidiol was unable to mimic the effects of Cannabis. In the 1970's the number of publications on cannabidiol reached a first peak, having the research focused mainly on the interaction with delta9-THC and its antiepileptic and sedative effects. The following two decades showed lower degree of interest, and the potential therapeutic properties of cannabidiol investigated were mainly the anxiolytic, antipsychotic and on motor diseases effects. The last five years have shown a remarkable increase in publications on cannabidiol mainly stimulated by the discovery of its anti-inflammatory, anti-oxidative and neuroprotective effects. These studies have suggested a wide range of possible therapeutic effects of cannabidiol on several conditions, including Parkinson's disease, Alzheimer's disease, cerebral ischemia, diabetes, rheumatoid arthritis, other inflammatory diseases, nausea and cancer. CONCLUSION: In the last 45 years it has been possible to demonstrate that CBD has a wide range of pharmacological effects, many of which being of great therapeutic interest, but still waiting to be confirmed by clinical trials.

OBJETIVO: O objetivo desta revisão é descrever a evolução histórica das pesquisas sobre o canabidiol. MÉTODO: Esta revisão foi conduzida utilizando-se bases de dados eletrônicas (Medline, Web of Science e SciELO). DISCUSSÃO: Após a elucidação de sua estrutura química, em 1963, os estudos iniciais do canabidiol demonstraram que ele não foi capaz de mimetizar os efeitos da maconha. Na década de 70, o número de publicações sobre o canabidiol atingiu um primeiro pico, com as investigações centrando-se principalmente na sua interação com o delta9-THC e nos seus efeitos antiepiléptico e sedativo. As duas décadas seguintes apresentaram um menor nível de interesse e as propriedades terapêuticas potenciais do canabidiol investigadas foram, principalmente, as ansiolíticas, antipsicóticas e seus efeitos sobre as doenças motoras. Os últimos cinco anos têm demonstrado um notável aumento de publicações sobre o canabidiol, principalmente estimulado pela descoberta dos seus efeitos anti-inflamatório, anti-oxidativo e neuroprotetor. Estes estudos têm sugerido uma vasta gama de possíveis efeitos terapêuticos da canabidiol em várias condições, incluindo doença de Parkinson, doença de Alzheimer, isquemia cerebral, diabetes, náusea, câncer, artrite reumatóide e outras doenças inflamatórias. CONCLUSÃO: Nos últimos 45 anos, foi possível demonstrar uma vasta gama de efeitos farmacológicos do canabidiol, muitos dos quais são de grande interesse terapêutico, que ainda necessitam ser confirmados por estudos clínicos.

Neuropsychological dysfunction related to earlier occupational exposure to mercury vapor

We assessed the neuropsychological test performances of 26 patients (mean age = 41.5 ± 6.1 years; mean years of education = 9.8 ± 1.8; 20 males) diagnosed with chronic occupational mercurialism who were former workers at a fluorescent lamp factory. They had been exposed to elemental mercury for an average of 10.2 ± 3.8 years and had been away from this work for 6 ± 4.7 years. Mean urinary mercury concentrations 1 year after cessation of work were 1.8 ± 0.9 æg/g creatinine. Twenty control subjects matched for age, gender, and education (18 males) were used for comparison. Neuropsychological assessment included attention, inhibitory control, verbal and visual memory, verbal fluency, manual dexterity, visual-spatial function, executive function, and semantic knowledge tests. The Beck Depression Inventory and the State and Trait Inventory were used to assess depression and anxiety symptoms, respectively. The raw score for the group exposed to mercury indicated slower information processing speed, inferior performance in psychomotor speed, verbal spontaneous recall memory, and manual dexterity of the dominant hand and non-dominant hand (P < 0.05). In addition, the patients showed increased depression and anxiety symptoms (P < 0.001). A statistically significant correlation (Pearson) was demonstrable between mean urinary mercury and anxiety trait (r = 0.75, P = 0.03). The neuropsychological performances of the former workers suggest that occupational exposure to elemental mercury has long-term effects on information processing and psychomotor function, with increased depression and anxiety also possibly reflecting the psychosocial context.

OBJETIVO: Determinar, em adolescentes de baixa renda, a prevalência de transtornos psiquiátricos durante a gravidez, a prevalência de uso de cocaína e maconha no terceiro trimestre de gestação e descrever suas características sociodemográficas. MÉTODO: Mil adolescentes grávidas foram avaliadas por meio do Composite International Diagnostic Interview e de um questionário sociodemográfico e socioeconômico no centro obstétrico de um hospital público de São Paulo. Dessas, foi colhida amostra para análise de fios de cabelo.RESULTADOS: Das mil pacientes entrevistadas, 53,6% têm baixa renda, 60,2% abandonaram a escola, 90,4% estão desempregadas e 92,5% são financeiramente dependentes, 6% usaram drogas durante o terceiro trimestre da gravidez (maconha: 4%, cocaína: 1,7%, ambos: 0,3%) e 27,6% tiveram ao menos um transtorno psiquiátrico. Os diagnósticos mais freqüentes foram: depressão (12,9%), transtorno de estresse pós-traumático (10,0%) e ansiedade (5,6%). DISCUSSÃO: Famílias desestruturadas, evasão escolar, desemprego e baixa capacitação profissional são fatores que contribuem para a manutenção desta situação socioeconômica desfavorável, cenário no qual são elementos importantes a alta prevalência de uso de cocaína e maconha no 3º trimestre da gravidez e de transtornos psiquiátricos.

Cannabidiol, a Cannabis sativa constituent, as an antipsychotic drug

A high dose of delta9-tetrahydrocannabinol, the main Cannabis sativa (cannabis) component, induces anxiety and psychotic-like symptoms in healthy volunteers. These effects of delta9-tetrahydrocannabinol are significantly reduced by cannabidiol (CBD), a cannabis constituent which is devoid of the typical effects of the plant. This observation led us to suspect that CBD could have anxiolytic and/or antipsychotic actions. Studies in animal models and in healthy volunteers clearly suggest an anxiolytic-like effect of CBD. The antipsychotic-like properties of CBD have been investigated in animal models using behavioral and neurochemical techniques which suggested that CBD has a pharmacological profile similar to that of atypical antipsychotic drugs. The results of two studies on healthy volunteers using perception of binocular depth inversion and ketamine-induced psychotic symptoms supported the proposal of the antipsychotic-like properties of CBD. In addition, open case reports of schizophrenic patients treated with CBD and a preliminary report of a controlled clinical trial comparing CBD with an atypical antipsychotic drug have confirmed that this cannabinoid can be a safe and well-tolerated alternative treatment for schizophrenia. Future studies of CBD in other psychotic conditions such as bipolar disorder and comparative studies of its antipsychotic effects with those produced by clozapine in schizophrenic patients are clearly indicated.

This study includes a random sample of sixty eight families [68] where the parent [male] is considered to be alcoholic according to W.H.O definition. Chronic alcoholism is almost exclusively confined to men in Sudan. It was clear from the result that the alcoholic, his wife, his children, his work and the society that contained him; all suffered the ill effects of Alcoholism. These ill effects are elaborated and put in statistical terms

A retrospective survey on side effects of praziquantel among 25,693 cases of schistosomiasis japonica.

A retrospective survey involving 25,693 persons was carried out in four provinces and the city of Shanghai, China between December 1981 until May 1982 to document relatively serious side effects of praziquantel used in a mass treatment programme for schistosomiasis japonica. Only 122 or 0.47% of those participating in the study had experienced relatively serious side reactions to the drug. Most had only one kind of side effects but two or more were recorded in a few patients. Neuropsychiatric reactions were seen in 39 persons (0.15%,) cardiovascular reactions in 37 (0.14%), hepatic changes in four (0.02%), dermatological reactions in 18 (0.07%) and delayed reactions resulting in fatigue and inability to work in 29 (0.11%). Praziquantel remains the drug of choice for the treatment of oriental schistosomiasis, it is highly effective and although side effects are minimal, caution should be taken in the treatment of chronic disease with heart failure, ascites, poor hepatic compensation and renal failure.
