Tecnologia: Duloxetina e outros antidepressivos disponíveis no Sistema Único de Saúde (amitriptilina, nortriptilina, clomipramina, fluoxetina e bupropiona). Indicação: Tratamento do primeiro episódio depressivo no transtorno de depressão maior em adultos. Pergunta: A duloxetina é mais eficaz e tolerável que a amitriptilina, nortriptilina, clomipramina, fluoxetina e bupropiona para o tratamento do primeiro episódio de depressão maior em adultos? Métodos: Revisão rápida de evidências (overview) de revisões sistemáticas, com levantamento bibliográfico realizado na base de dados PUBMED, utilizando estratégia estruturada de busca. A qualidade metodológica das revisões sistemáticas foi avaliada com AMSTAR-2 (Assessing the Methodological Quality of Systematic Reviews). Resultados: Foi selecionada 1 revisão sistemática, que atendia aos critérios de inclusão. Conclusão: Os antidepressivos, comparados ao placebo, tinham maior taxa de resposta, taxa de remissão e taxa de descontinuação devido a efeitos colaterais, no tratamento de curto prazo. Duloxetina tinha taxa de resposta similar a amitriptilina, clomipramina, fluoxetina e bupropiona. Duloxetina e amitriptilina tinham maior taxa de remissão que fluoxetina. Comparando-se as taxas de abandono de tratamento devido a efeitos colaterais, clomipramina era menos seguro, amitriptilina, bupropiona e duloxetina eram parecidos entre si, e fluoxetina era o antidepressivo mais seguro

Technology: Duloxetine and other antidepressants available in the Brazilian Public Health System (amitriptyline, nortriptyline, clomipramine, fluoxetine and bupropion). Indication: Treatment of the first depressive episode in adult major depressive disorder. Question: Is duloxetine more effective and tolerable than amitriptyline, nortriptyline, clomipramine, fluoxetine and bupropion for the treatment of first episode of major depression in adults? Methods: Rapid response review of evidence (overview) from systematic reviews, with a bibliographic search in the PUBMED database, using a structured strategy. The methodological quality of systematic reviews was assessed with AMSTAR-2 (Methodological Quality Assessment of Systematic Reviews). Results: One systematic review was selected, which met the inclusion criteria. Conclusion: In short-term treatment, antidepressants, compared to placebo, had a higher rate of response, rate of remission and rate drop-out due to side effects. Duloxetine had a similar response rate to amitriptyline, clomipramine, fluoxetine and bupropion. Duloxetine and amitriptyline had higher remission rates than fluoxetine. Comparing rates of dropout due to side effects, clomipramine had the worst rates, amitriptyline, bupropion, and duloxetine were similar to each other, and fluoxetine had the better rates

Uma abordagem atual da utilização de antidepressivos no manejo da depressão pós-parto / A current approach to the use of antidepressants in the management of postpartum depression / Enfoque actual de la utilización de antidepresivos en el manejo de la depresión postparto

OBJETIVO: caracterizar a utilização de antidepressivos no manejo da depressão pós-parto. MÉTODO: empregou-se uma revisão integrativa de literatura, das bases de dados PubMed e Biblioteca Virtual em Saúde, com aplicação de descritores, visando responder a pergunta norteadora do trabalho, entre os dias 25 de fevereiro e 10 de março de 2019. Com base nos critérios de inclusão e exclusão, foram selecionados 23 artigos que, posteriormente, foram submetidos à categorização. RESULTADOS: a sertralina deve ser a droga de escolha para o tratamento farmacológico da depressão puerperal. Constatou-se também, que a utilização profilática de antidepressivos em mulheres susceptíveis é contestável e pouco se sabe sobre os possíveis efeitos colaterais. Ademais, foi encontrado que não há consenso sobre a superioridade da terapia farmacológica em detrimento às psicoterapias. CONCLUSÃO: há evidencias que fundamentam o uso de sertralina, paroxetina, duloxetina, nortriptilina e imipramina para tratar mulheres com depressão pós-parto, sendo a amamentação sempre recomendada. Ressalta-se que emerge a necessidade de estudos com amostras representativas para validar ou restringir o uso de psicofármacos na profilaxia da depressão puerperal.

OBJECTIVE: this study aimed to characterize the use of antidepressants in the management of postpartum depression. METHOD: an integrative literature review of the PubMed and Virtual Health Library databases was used, with the application of descriptors, aiming to answer the guiding question of the work, between February 25th and March 10th, 2019. Based on the inclusion and exclusion criteria, 23 articles were selected that were later submitted to categorization. RESULTS: sertraline should be the drug of choice for the pharmacological treatment of puerperal depression. It was also found that the prophylactic use of antidepressants in susceptible women is controversial and little is known about the possible side effects. In addition, it was found that there is no consensus on the superiority of pharmacological therapy to the detriment of psychotherapies. CONCLUSION: there is evidence supporting the use of sertraline, paroxetine, duloxetine, nortriptyline and imipramine to treat women with postpartum depression, and breastfeeding is always recommended. It is worth noting that the need for studies with representative samples to validate or restrict the use of psychotropic drugs in the prophylaxis of puerperal depression emerges.

Spontaneous Ejaculation Due to Duloxetine: A Case Report

ABSTRACT Ejaculation is controlled by both the sympathetic and parasympathetic system and consists of an emission and expulsion phase. Ejaculation latency time is regulated by the sympathetic system. Hypothetically, by reducing ejaculatory latency time, spontaneous ejaculation can occur. Extending the duration of ejaculation is a well-known side effect of antidepressants, especially selective serotonin reuptake inhibitors, serotonin and norepinephrine reuptake inhibitors and noradrenergic reuptake inhibitors. Adrenergic drugs are sometimes used as treatment for delayed ejaculation. A spontaneous ejaculation due to the use of these drugs has rarely been reported. Although most reports of spontaneous ejaculations are related to the use of venlafaxine and reboxetine, this study is based on a case of the side effect of duloxetine.

Tratamiento conservador de la artrosis de cadera / Conservative treatment of hip osteoarthritis

Ante un escenario clínico de coxalgia por artrosis de cadera se planteó la necesidad de conocer los tratamientos con-servadores más seguros y efectivos para el manejo del dolor. El tratamiento de la artrosis requiere un enfoque integral e individualizado en función de las preferencias del paciente para lograr el máximo beneficio clínico. Existen numerosas estrategias útiles para el manejo del dolor en pacientes con artrosis de cadera siendo fuertemente recomendados de inicio la actividad física, los antiinflamatorios no esteroideos (AINE) orales y en ciertos casos los corticoides intraarticulares, tramadol o duloxetina, siempre asociado con la actividad física. Los ejercicios más recomendados son los aeróbicos y el Tai Chi o yoga. (AU)

Faced with a clinical scenario of coxalgia due to hip osteoarthritis, the need to know the safest and most effective conservative treatments for pain management arose. The treatment of osteoarthritis requires a comprehensive and individualised approach based on the patient's preferences to achieve maximum clinical benefit. There are numerous useful strategies for pain management in patients with hip osteoarthritis being strongly recommended from the beginning such as physical activity, oral non-steroidal anti-inflammatory drugs (NSAID) and in certain cases intra-articular corticosteroids, tramadol or duloxetine, always associated with physical activity. The most recommended exercises are aerobics and Tai Chi or yoga. (AU)

Treatment data from the Brazilian fibromyalgia registry (EpiFibro)

Abstract Background: EpiFibro (Brazilian Epidemiological Study of Fibromyalgia) was created to study patients with fibromyalgia (FM). Patients were included since 2011 according to the classification criteria for FM of the American College of Rheumatology of 1990 (ACR1990). Objective: To analyze the therapeutic measures prescribed by Brazilian physicians. Materials and methods: Cross-sectional study of a multicenter cohort. The therapeutic measures were described using descriptive statistics. Results: We analyzed 456 patients who had complete data in the registry. The mean age was 54.0 ± 11.9 years; 448 were women (98.2%). Almost all patients (98.4%) used medications, 62.7% received health education, and less than half reported practicing physical exercise; these modalities were often used in combination. Most patients who practiced exercises practiced aerobic exercise only, and a significant portion of patients combined it with flexibility exercises. The most commonly used medication was amitriptyline, followed by cyclobenzaprine, and a minority used medication specifically approved for FM, such as duloxetine and pregabalin, either alone or in combination. Combinations of two or three medications were observed, with the combination of fluoxetine and amitriptyline being the most frequent (18.8%). Conclusion: In this evaluation of the care of patients with FM in Brazil, it was found that the majority of patients are treated with a combination of pharmacological measures. Non-pharmacological methods are underused, with aerobic exercise being the most commonly practiced exercise type. The most commonly prescribed single drug was amitriptyline, and the most commonly prescribed combination was fluoxetine and amitriptyline. Drugs specifically approved for FM are seldom prescribed.(AU)

Comparing the efficacy and safety of duloxetine and amitriptyline in the treatment of fibromyalgia: overview of systematic reviews

Abstract Background: Duloxetine and amitriptyline are antidepressants used in the treatment of fibromyalgia. In published systematic reviews, there is no agreement about which drug is more effective and safer. This study aimed to compare evidence of the efficacy and safety of duloxetine compared with amitriptyline in the treatment of adult patients with fibromyalgia. This work contributes to guiding clinicians on the use of duloxetine or amitriptyline for the treatment of fibromyalgia and provides information for public health decision-makers. Methods: Overview of systematic reviews of clinical trials comparing duloxetine and amitriptyline in the treatment of fibromyalgia. The reviews were screened in Cochrane, PubMed, EMBASE, and SRDR with no restrictions on language and year of publication, considering that the research was conducted in July 2018 and updated until May 2020. The selection was based on the following criteria: adult patients with a diagnosis of fibromyalgia treated with duloxetine or amitriptyline, comparing the efficacy and safety in pain, fatigue, sleep, and mood disorder symptoms and quality of life, in addition to the acceptability of these antidepressants. The methodological quality and strength of evidence were assessed using the AMSTAR and GRADE instruments. Results: Eight systematic reviews were selected. Amitriptyline had low evidence for pain, moderate evidence for sleep and fatigue, and high evidence for quality of life. Duloxetine had high quality of evidence in patients with mood disorders. With low evidence, duloxetine has higher acceptability, but is safer in older patients, while amitriptyline is safer for non-elderly individuals. Conclusion: Both antidepressants are effective in the treatment of fibromyalgia, differing according to the patient's symptoms and profile. Registration: PROSPERO: CRD42019116101.(AU)

Psychometric properties of Turkish version of Jenkins sleep scale in fibromyalgia syndrome

Abstract Background: Fibromyalgia syndrome (FMS) has adverse effects on the quality of sleep. The aim of this study was to investigate the validity and reliability of Jenkins Sleep Scale (JSS-TR) in Turkish FMS patients. Methods: FMS patients who met the 2016 fibromyalgia diagnostic criteria were included in the study. Clinical and demographic data of the patients were noted. The relationship between this scale and other functional parameters such as Pittsburgh Sleep Quality Index (PSQI), European Quality of Life Scale-5 Dimensions (EQ-5D), Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI) was examined. Fibromyalgia Impact Questionnaire (FIQ) was used to evaluate the functional status of the patients and the progression of the disease. Test-retest reliability was calculated by re-applying the questionnaire to patients at 2-week intervals. Duloxetine treatment was initiated in newly diagnosed patients and sensitivity to change was tested at the end of the treatment. Spearman correlation coefficient was used. P < 0.05 was accepted as significant. Results: Eighty-one FMS patients (71 females, 10 males) were included in the study. The mean age was 44.2 ± 10.7 years. The strongest correlation of JSS-TR was with another sleep questionnaire, PSQI (rho = 0.79, p < 0.0005). The correlation with other functional parameters and FIQ was moderate. In test-retest validity, intraclass correlation coefficient was found to be 0.98 (p < 0.0005). Chronbach α value calculated for internal consistency was found to be 0.741. Conclusions: JSS-TR is a valid, simple and feasible sleep instrument that can be easily applied to FMS patients both in researches and clinical settings.(AU)

La depresión: un desafío en la práctica médica general / La depresión: un desafío en la práctica médica general

Asociada o no a una enfermedad orgánica, la depresión tiene gran prevalencia en la práctica médica pero es subdiagnosticada. El trastorno del ánimo suele coexistir con variadas quejas somáticas y dolores crónicos, configurando síndromes mixtos con un diagnóstico diferencial complejo. En este artículo se describen distintas presentaciones clínicas de la depresión en medicina general, con énfasis en los estados depresivos atípicos, depresiones enmascaradas muy relevantes por su frecuencia y consecuencias: depresión posquirúrgica, cuadros dolorosos crónicos como cefaleas o lumbago, la fatiga crónica y la fibromialgia. Solo el reconocimiento y diagnóstico de la depresión subyacente posibilitará la implementación de las adecuadas intervenciones terapéuticas. Se revisan también algunas recomendaciones para el uso de antidepresivos en atención primaria y la eventual consulta psiquiátrica. (AU)

Associated or not with an organic disease, depression has a high prevalence in medical practice but is underdiagnosed. The mood disorder usually coexists with varied somatic complaints and chronic pain, forming mixed syndromes with a complex differential diagnosis. This article describes different clinical presentations of depression in general medicine, with emphasis on atypical depressive states, masked depressions very relevant for their frequency and consequences: post-surgical depression, chronic painful conditions such as headaches or lumbago, chronic fatigue and fibromyalgia. Only the recognition and diagnosis of the underlying depression will enable the implementation of appropriate therapeutic interventions. Some recommendations for the use of antidepressant drugs in primary care and the eventual psychiatric consultation are also reviewed. (AU)

Efeitos citotóxicos da duloxetina nas linhagens celulares MKN45 e NIH3T3 e efeitos genotóxicos em linfócitos sanguíneos periféricos humanos / Cytotoxic effects of duloxetine on mkn45 and nih3t3 cell lines and genotoxic effects on human peripheral blood lymphocytes

ABSTRACT BACKGROUND: Gastric cancer is the second leading cause of cancer-related death globally. Unfortunately, the survival rate of the gastric cancer patients who underwent chemotherapy following surgery has been less than a half. Besides, chemotherapy has many side effects. Current evidence suggests that some antidepressants like duloxetine have growth-inhibiting effects against a number of cancer cell lines. OBJECTIVE: Thus, the aim of this study was to determine the cytotoxic and genotoxic effects of duloxetine on gastric cancer. METHODS: In this regard, the cytotoxicity and genotoxicity of duloxetine were investigated in MKN45 and NIH3T3 cell lines by MTT assay and on peripheral blood lymphocytes by MN assay. For this purpose, cells were cultured in 96 wells plate. Stock solutions of duloxetine and cisplatin were prepared. After cell incubation with different concentrations of duloxetine (1, 10, 25, 50, 100 and 200 μL), MTT solution was added. For micronucleus assay fresh blood was added to RPMI culture medium 1640 supplemented, and different concentrations of duloxetine (1, 10, 25, 50, 100 and 200 μL) were added. RESULTS: The cytotoxicity of duloxetine on MKN45 cancer cell line and NIH3T3 normal cell line were studied followed by MTT assay. duloxetine exhibited higher IC50 in the MKN45 cells in comparison with the NIH3T3 cells. In addition, genotoxic effect of duloxetine was evaluated by micronucleus assay. The results revealed that duloxetine induced more DNA damage at 100 and 200 μM and no significant difference at 200 μM with respect to cisplatin, but it had less genotoxic effects at 100 and 50 μM concentrations. CONCLUSION: Although, in this study, duloxetine had less genotoxicity than cisplatin in concentrations under 200 μM and showed cytotoxic effects as well, due to its IC50, it cannot be considered as a better choice for gastric cancer therapies with respect to cisplatin as a common anticancer drug.

RESUMO CONTEXTO: O câncer gástrico é a segunda principal causa de morte relacionada ao câncer globalmente. Infelizmente, a taxa de sobrevivência dos pacientes com câncer gástrico que se submeteram à quimioterapia após a cirurgia, tem sido inferior à metade. Além disso, a quimioterapia tem muitos efeitos colaterais. Evidências atuais sugerem que alguns antidepressivos como a duloxetina têm efeitos inibidores de crescimento contra um número de linhas de células cancerosas. OBJETIVO: Assim, o objetivo deste estudo foi determinar os efeitos citotóxicos e genotóxicos da duloxetina sobre o câncer gástrico. MÉTODOS: A este respeito, a citotoxicidade e a genotoxicidade da duloxetina foram investigadas em linhas celulares MKN45 e NIH3T3 por ensaio de MTT e por ensaio de MN em linfócitos periféricos de sangue. Para este efeito, as células foram cultivadas em 96 placas. Soluções de estoque de duloxetina e cisplatina foram preparadas. Após incubação celular com diferentes concentrações de duloxetina (1, 10, 25, 50, 100 e 200 μL), a solução de MTT foi adicionada. Para o teste do micronúcleo o sangue fresco foi adicionado ao meio de cultura RPMI 1640 suplementado, e as concentrações diferentes de duloxetina (1, 10, 25, 50, 100 e 200 μL) foram adicionadas. RESULTADOS: A citotoxicidade da duloxetina na linha celular cancerosa MKN45 e NIH3T3 linha celular normal foram estudadas e seguidas pelo ensaio de MTT. A duloxetina exibiu maior IC50 nas células MKN45 em comparação com as células NIH3T3. Além disso, o efeito genotóxico da duloxetina foi avaliado pelo ensaio de micronúcleos. Os resultados revelaram que a duloxetina induziu mais dano de DNA em 100 e 200 μM e não houve diferença significativa em 200 μM em relação à cisplatina, mas teve menos efeitos genotóxicos nas concentrações de 100 e 50 μM. CONCLUSÃO: Embora, neste estudo, a duloxetina tenha menos genotoxicidade do que a cisplatina em concentrações inferiores a 200 μm e também tenha mostrado efeitos citotóxicos, devido ao seu IC50, não pode ser considerada como uma escolha terapêutica melhor para o câncer gástrico no que diz respeito à cisplatina como uma droga anticâncer comum.

Effectiveness of Pregabalin for Treatment of Burning Mouth Syndrome

Treatment of burning mouth syndrome (BMS) is challenging because there is no consensus regarding pharmalogical or nonpharmalogical therapies. The use of anticonvulsants is controversial. We present nine patients BMS who respond to pregabalin. They were diagnosed secondary BMS except two. Etiologic regulations were made firstly in patients with secondary BMS but symptoms did not decrease. We preferred pregabalin in all patients and got good results. Furthermore the addition of pregabalin to the treatment of two patients who did not respond adequately to duloxetine provided good results. We are only aware that pregabalin may reduce symptoms as a result of case reports. We believe that the diagnosis of pathologic etiology with appropriate diagnostic tests will result in better outcomes in treatment.

Pharmacological Therapy in Panic Disorder: Current Guidelines and Novel Drugs Discovery for Treatment-resistant Patient

Panic disorder (PD) being one of the most intensively investigated anxiety disorders is considered a heterogeneous psychiatric disease which has difficulties with early diagnosis. The disorder is recurrent and usually associated with low remission rates and high rates of relapse which may exacerbated social and quality of life, causes unnecessary cost and increased risk for complication and suicide. Current pharmacotherapy for PD are available but these drugs have slow therapeutic onset, several side effects and most patients do not fully respond to these standard pharmacological treatments. Ongoing investigations indicate the need for new and promising agents for the treatment of PD. This article will cover the importance of immediate and proper treatment, the gap in the current management of PD with special emphasis on pharmacotherapy, and evidence regarding the novel anti-panic drugs including the drugs in developments such as metabotropic glutamate (mGlu 2/3) agonist and levetiracetam. Preliminary results suggest the anti-panic properties and the efficacy of duloxetine, reboxetine, mirtazapine, nefazodone, risperidone and inositol as a monotherapy drug. Apart for their effectiveness, the aforementioned compounds were generally well tolerated compared to the standard available pharmacotherapy drugs, indicating their potential therapeutic usefulness for ambivalent and hypervigilance patient. Further strong clinical trials will provide an ample support to these novel compounds as an alternative monotherapy for PD treatment-resistant patient.

Antidepressants in Spine Surgery: A Systematic Review to Determine Benefits and Risks

Antidepressant drugs can be advantageous in treating psychiatric and non-psychiatric illnesses, including spinal disorders. However, spine surgeons remain unfamiliar with the advantages and disadvantages of the use of antidepressant drugs as a part of the medical management of diseases of the spine. Our review article describes a systematic method using the PubMed/Medline database with a specific set of keywords to identify such benefits and drawbacks based on 17 original relevant articles published between January 2000 and February 2018; this provides the community of spine surgeons with available cumulative evidence contained within two tables illustrating both observational (10 studies; three cross-sectional, three case-control, and four cohort studies) and interventional (seven randomized clinical trials) studies. While tricyclic antidepressants (e.g., amitriptyline) and duloxetine can be effective in the treatment of neuropathic pain caused by root compression, venlafaxine may be more appropriate for patients with spinal cord injury presenting with depression and/or nociceptive pain. Despite the potential associated consequences of a prolonged hospital stay, higher cost, and controversial reports regarding the lowering of bone mineral density in the elderly, antidepressants may improve patient satisfaction and quality of life following surgery, and reduce postoperative pain and risk of delirium. The preoperative treatment of preexisting psychiatric diseases, such as anxiety and depression, can improve outcomes for patients with spinal cord injury-related disabilities; however, a preoperative platelet function assay is advocated prior to major spine surgical procedures to protect against significant intraoperative blood loss, as serotonergic antidepressants (e.g., selective serotonin reuptake inhibitors) and bupropion can increase the likelihood of bleeding intraoperatively due to drug-induced platelet dysfunction. This comprehensive review of this evolving topic can assist spine surgeons in better understanding the benefits and risks of antidepressant drugs to optimize outcomes and avoid potential hazards in a spine surgical setting.

Combined Use of Duloxetine and Olanzapine in the Treatment of Urologic Chronic Pelvic Pain Syndromes Refractory to Conventional Treatment: A Case Report

Patients with urologic chronic pelvic pain syndromes (UCPPS) report interstitial cystitis/bladder pain syndrome and/or chronic prostatitis/chronic pelvic pain syndrome. The pathogenesis of these syndromes remains unclear and there is currently no standard treatment. UCPPS is, therefore, often misdiagnosed and its management is complex. The present case report involves a 62-year-old male patient with UCPPS whose main presentation is painful bladder filling and painful urgency refractory to conventional treatment with medication, which was successfully treated with the combined use of duloxetine and olanzapine. The combined use of duloxetine and olanzapine may become a new therapeutic option in the management of UCPPS.

Neuroprotective Effect of Duloxetine on Chronic Cerebral Hypoperfusion-Induced Hippocampal Neuronal Damage

Chronic cerebral hypoperfusion (CCH), which is associated with onset of vascular dementia, causes cognitive impairment and neuropathological alterations in the brain. In the present study, we examined the neuroprotective effect of duloxetine (DXT), a potent and balanced serotonin/norepinephrine reuptake inhibitor, on CCH-induced neuronal damage in the hippocampal CA1 region using a rat model of permanent bilateral common carotid arteries occlusion. We found that treatment with 20 mg/kg DXT could attenuate the neuronal damage, the reduction of phosphorylations of mTOR and p70S6K as well as the elevations of TNF-α and IL-1β levels in the hippocampal CA1 region at 28 days following CCH. These results indicate that DXT displays the neuroprotective effect against CCH-induced hippocampal neuronal death, and that neuroprotective effect of DXT may be closely related with the attenuations of CCH-induced decrease of mTOR/p70S6K signaling pathway as well as CCH-induced neuroinflammatory process.

Therapeutic alternatives in painful diabetic neuropathy: a meta-analysis of randomized controlled trials

BACKGROUND: One of the most frequent problems caused by diabetes is the so called painful diabetic neuropathy. This condition can be treated through numerous types of therapy. The purpose of this study was to analyze, as a meta-analysis, different treatments used to alleviate painful diabetic neuropathy, with the aim of generating results that help making decisions when applying such treatments to tackle this pathology. METHODS: A search was conducted in the main databases for Health Sciences, such as PUBMED, Web of Science (WOS), and IME biomedicina (Spanish Medical Reports in Biomedicine), to gather randomized controlled trials about treatments used for painful diabetic neuropathy. The analyzed studies were required to meet the inclusion criteria selected, especially those results related to pain intensity. RESULTS: Nine randomized controlled trials were chosen. The meta-analysis shows significant positive effects for those treatments based on tapentadol [g: −1.333, 95% CI (−1.594; −1.072), P < 0.05], duloxetine [g: −1.622, 95 % CI (−1.650; −1.594), P < 0.05], pregabalin [g: −0.607, 95% CI (−0.980; −0.325), P < 0.05], and clonidine [g: −0.242, 95 % CI (−0.543; −0.058), P < 0.05]. CONCLUSIONS: This meta-analysis indicates the effectiveness of the treatments based on duloxetine, gabapentin and pregabalin, as well as other drugs, such as tapentadol and topic clonidine, whose use is better prescribed in more specific situations. The results provided can help increase the knowledge about the treatment of painful diabetic neuropathy and also in the making of clinical practice guidelines for healthcare professionals.

TeleCondutas: ansiedade / TeleGuides: anxiety

A ansiedade pode ser vista como sintoma psiquiátrico e/ou como reação emocional não patológica associada a diversos contextos de vida. Ela representa um sinal de alarme a determinado estímulo percebido pelo indivíduo como perigoso. Em geral, é composta por uma combinação variável de sintomas físicos, pensamentos catastróficos e alterações de comportamento. A ansiedade pode ser compreendida como mecanismo evolutivo, isto é, uma ferramenta que nos ajuda a detectar o perigo e adotar as medidas necessárias para lidar com ele. No entanto, esse recurso adaptativo muitas vezes encontra-se desregulado, causando sofrimento e prejuízo ao desempenho social e/ou profissional. A ansiedade se torna um transtorno psiquiátrico quando representa emoção desconfortável e inconveniente, surgindo na ausência de um estímulo externo claro ou com magnitude suficiente para justificá-la, e apresenta intensidade, persistência e frequência desproporcionais. Estudos epidemiológicos indicam os transtornos de ansiedade como os mais prevalentes dentre os transtornos psiquiátricos. Na grande maioria dos casos, não há como estabelecer uma causa específica aos transtornos aqui tratados. A interação entre fatores genéticos e ambientais resume a etiologia atualmente proposta e aceita.

Botulinum Toxin Type A Injection for Neuropathic Pain in a Patient With a Brain Tumor: A Case Report

Neuropathic pain is usually managed pharmacologically, rather than with botulinum toxin type A (BTX-A). However, medications commonly fail to relieve pain effectively or have intolerable side effects. We present the case of a 62-year-old man diagnosed with an intracranial chondrosarcoma, which was removed surgically and treated with radiation therapy. He suffered from neuropathic pain despite combined pharmacological therapy with gabapentin, amitriptyline, tramadol, diazepam, and duloxetine because of adverse effects. BTX-A (100 units) was injected subcutaneously in the most painful area in the posterior left thigh. Immediately after the injection, his pain decreased significantly from 6/10 to 2/10 on a visual analogue scale. Pain relief lasted for 12 weeks. This case report describes intractable neuropathic pain caused by a brain tumor that was treated with subcutaneous BTX-A, which is a useful addition for the management of neuropathic pain related to a brain tumor.

Randomized controlled trials of serotonin-norepinephrine reuptake inhibitor in treating major depressive disorder in children and adolescents: a meta-analysis of efficacy and acceptability

New generation antidepressant therapies, including serotonin-norepinephrine reuptake inhibitor (SNRIs), were introduced in the late 1980s; however, few comprehensive studies have compared the benefits and risks of various contemporary treatments for major depressive disorder (MDD) in young patients. A comprehensive literature search of PubMed, Cochrane, Embase, Web of Science, and PsycINFO databases was conducted from 1970 to January 2015. Only clinical trials that randomly assigned one SNRI or placebo to patients aged 7 to 18 years who met the diagnostic criteria for major depressive disorder were included. Treatment success, dropout rate, and suicidal ideation/attempt outcomes were measured. Primary efficacy was determined by pooling the risk ratios (RRs) of treatment response and remission. Acceptability was determined by pooling the RRs of dropouts for all reasons and for adverse effects as well as suicide-risk outcomes. Five trials with a total of 973 patients were included. SNRIs were not significantly more effective than placebo for treatment response but were for remission. The comparison of patients taking SNRIs that dropped out for all reasons and those taking placebo did not reach statistical significance. Significantly more patients taking SNRIs dropped out for adverse effects than those taking placebo. No significant difference was found in suicide-related risk outcomes. SNRI therapy does not display a superior efficacy and is not better tolerated compared to placebo in these young patients. However, duloxetine has a potential beneficial effect for depression in young populations, showing a need for further research.

Oral pharmacological therapy for urinary incontinence

Urinary incontinence (UI) has been a serious health problem which can significantly affect quality of life. UI may occur at any age but more common in the elderly population. Many conditions may leak to UI and differential diagnosis is critical to guide appropriate manage strategy. After a brief description of the pathophysiology, classification, and diagnostic evaluation of UI, this review highlights oral pharmacological therapy mainly in clinical point of view. For urge UI, antimuscarinic are the most commonly used medication supported with high level of evidence. Antimuscarinics competitively block muscarinic receptors with variations in selectivity for the different subtypes. Common adverse effects are dry mouth, constipation, and blurred vision. High caution for cognitive function should be applied in the use of antimuscarinics in the elderly. Mirabegron, a beta3-agonist, is a new class of drug targeting urge UI, which reported similar efficacy with antimuscarinics and favorable adverse effect profile. For stress UI, various type of medications have been clinically investigated but so far none showed satisfactory resolution of stress UI. Duloxetine is the only medication approved for stress UI in European countries but not in US Food and Drug Administration and Korean Food and Drug Administration due to low benefit-risk profile for UI. Conclusively, pharmacological therapy should be tailored to the type of UI. Recent options of medications may give further treatment possibilities for the optimal treatment for each patient.

Treatment of Persistent Somatoform Pain Disorder by Floating Needle Therapy and Duloxetine / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).</p><p><b>METHODS</b>Totally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.</p><p><b>RESULTS</b>(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).</p><p><b>CONCLUSIONS</b>Floating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.</p>
