Effects of medical therapy, alcohol, smoking, and endocrine disruptors on male infertility

Infertility affects up to 15% of the sexually active population, and in 50% of cases, a male factor is involved, either as a primary problem or in combination with a problem in the female partner. Because many commonly encountered drugs and medications can have a detrimental effect on male fertility, the medical evaluation should include a discussion regarding the use of recreational and illicit drugs, medications, and other substances that may impair fertility. With the knowledge of which drugs and medications may be detrimental to fertility, it may be possible to modify medication regimens or convince a patient to modify habits to decrease adverse effects on fertility and improve the chances of achieving a successful pregnancy. Concern is growing that male sexual development and reproduction have changed for the worse over the past 30 to 50 years. Although some reports find no changes, others suggest that sperm counts appear to be decreasing and that the incidence of developmental abnormalities such as hypospadias and cryptorchidism appears to be increasing, as is the incidence of testicular cancer. These concerns center around the possibility that our environment is contaminated with chemicals - both natural and synthetic - that can interact with the endocrine system.

Impact of health legislation on the sale of anorectics in a city in the Amazon region

OBJECTIVES: The International Narcotics Control Board released its 2005 annual report, highlighting the Brazil population as one of the largest consumers of anorectics. In Brazil, the National Health Surveillance Agency issued the resolution RDC 58/2007 in order to control the prescription and sale of such drugs. In Belém, the biggest city in the Brazilian Amazon region, this resolution came into force in 2008, leading to inspections of drugstores and magistral pharmacies. The aim of this work was to evaluate the consumption of psychotropic anorectic drugs and the impact of RDC 58/2007 on the prescription and dispensing of anorectics in drugstores and magistral pharmacies in Belém. METHODOLOGY: A retrospective quantitative and descriptive study was conducted of records from the Municipal Department of Health Surveillance of Belém, for 2005 to 2008. The differences in findings were regarded significant when p < 0.05. RESULTS: A total of 1,641 balance sheets of drugstores and magistral pharmacies were analyzed. Amfepramone was the most dispensed medication, followed by fenproporex and mazindol. The highest consumption of anorectics occurred in magistral pharmacies. In 2008, there was a significant reduction in dispensing of anorectics, in drugstores as well as in magistral pharmacies. CONCLUSIONS: This study showed that there was a decrease in the dispensing of anorectics after RDC 58/2007 came into force, and that the magistral pharmacies dispensed more of these drugs. This resolution is a remarkable tool in health control, where it is of great benefit to public health and contributes substantially to the rational use of medicines in Brazil.

Cardio-respiratory symptoms in panic disorder: a contribution from cognitive-behaviour therapy

Objective: To compare patients with panic disorder with agoraphobia treated with cognitive-behavioural therapy (CBT) associated with the medication with patients treated only with medication and verify the behaviour of the cardio-respiratory symptoms of both groups. Methods: Randomized sample in the Psychiatry Institute of the Federal University of Rio de Janeiro, divided in two groups of 25 participants each. Group 1 undertook 10 weekly sessions of CBT with one hour of duration each together with medication. Group 2, Control, were administered medication that only consisted of tricyclic anti-depressants and selective inhibitors of the re-uptake of serotonin. Evaluation instruments were applied at the beginning and to the end of the interventions. Results: According to the applied scales, group 1 showed statistically more significant results than group 2, with: reduction of panic attacks, cardio-respiratory symptoms, anticipatory anxiety, agoraphobia avoidance and fear of bodily sensations. Conclusion: Exposures (in vivo and interoceptive), especially for induction symptom exercises and relaxation, were considered essential to prepare patients with panic disorder to handle future cardio-respiratory symptoms and panic attacks with agoraphobia.

Adesão ao tratamento medicamentoso em pacientes do espectro esquizofrênico: uma revisão sistemática da literatura

OBJETIVO: Realizar revisão sistemática para avaliar a adesão medicamentosa ao tratamento em pacientes do espectro esquizofrênico. MÉTODO: As buscas dos artigos foram conduzidas nas seguintes bases de dados: PubMed/Medline, Lilacs, SciELO e PePSIC, considerando artigos publicados entre 2001 e 2010. Na estratégia de busca, foram utilizados descritores de acordo com sua definição no DeCS e no MeSH: "schizophrenia" and "patient adherence" or "patient compliance" or "medication adherence". As correspondências em português e espanhol foram respectivamente "esquizofrenia/esquizofrenia" e "cooperação do paciente/cooperácion del paciente" ou "adesão à medicação/cumplimiento de lá medicación". Também foram realizadas buscas manuais nas referências dos artigos selecionados. RESULTADOS: A busca bibliográfica resultou em 1.692 artigos. Contudo, apenas 54 preencheram os critérios para compor esta revisão. CONCLUSÕES: A maioria dos estudos sobre o tema foi realizada em países desenvolvidos, prejudicando a aplicação dos achados à nossa realidade. As taxas da adesão e os métodos utilizados para avaliação variaram bastante, porém os fatores associados à não adesão se repetiram, como falta de insight, comorbidade com uso de substâncias psicoativas, falta de apoio social, efeitos colaterais da medicação, comportamento violento, situação de rua, tentativa de suicídio, entre outros. Assim sendo, há necessidade da realização de mais estudos nacionais para investigar potenciais variáveis associadas a não adesão e suas consequências para a população estudada.

Is psychodynamic psychotherapy an effective intervention for individuals at ultra-high risk (UHR) of psychosis?: a case report

OBJECTIVE: To report a case and to discuss the use of psychodynamic psychotherapy (PD-P) to treat individuals at ultra-high risk (UHR) of psychosis. METHODS: An individual at UHR was followed up for 24 months. The baseline evaluation included a psychiatric interview, the Structured Interview for Prodromal Symptoms (SIPS), the Scale of Prodromal Symptoms (SOPS), and neuropsychological assessment. He underwent weekly sessions of PD-P for 12 months and was followed up for 12 months after the end of PD-P. The evaluations were at baseline, after 6-, 12-, and 24-month follow-up. No medication was prescribed during the 24-month follow-up. RESULTS: The prodromal symptoms remitted. The initial total score on the SIPS/SOPS was 37 points. After the first 12 months of PD-P, there was a reduction to 12 points on the SIPS/SOPS score, which stabilized in the 24-month follow-up. There was also a slight improvement in his performance on the neuropsychological evaluations. CONCLUSION: This case report suggests that PD-P can reduce prodromal symptoms; nevertheless, a better understanding of the specificity and efficacy of PD-P as an option of treatment for UHR individuals is needed.

Clozapine-induced severe eosinophilia: report of a case with good outcome

INTRODUCTION: Clozapine is the antipsychotic of choice in the treatment of refractory schizophrenia. However, its side effects, such as eosinophilia, may preclude its use. METHODS: Case report and literature review. RESULTS: Young woman, 19 years old, diagnosed with hebefrenic schizophrenia, admitted at Unicamp's psychiatry ward after psychotic symptoms relapse. Clozapine was started after unsuccessful attempts with risperidon and olanzapine. By the fourth week of clozapine use, eosinophils began to increase. Drug titration was stopped, but eosinophils counts continued to rise up, reaching the mark of 5200/mm³. Due to severity of psychotic symptoms and to the good response obtained with clozapine, we decided to investigate organs involvement before withdrawing the medication. As the patient had no organs involvement, clozapine was maintained and one month after eosinophils peak, it was already normalized. CONCLUSION: Eosinophilia should not necessarily lead to clozapine's withdrawal. Patients who present eosinophilia must be at rigorous observation for organs involvement, and if there is no such involvement, clozapine might be maintained, considering the possible benign and transitory nature of the eosinophils count elevation.

Electroconvulsive therapy and anticoagulation after pulmonary embolism: a case report

Introduction Electroconvulsive therapy (ECT) is considered the most effective treatment for catatonia regardless its underlying condition. The rigid fixed posture and immobility observed in catatonia may lead to several clinical complications, of which, pulmonary embolism (PE) is one of the most severe. The rapid improvement of the psychiatric condition in catatonia-related PE is essential, since immobility favors the occurrence of new thromboembolic events and further complications. In that scenario, ECT should be considered, based on a risk-benefit analysis, aiming at the faster resolution of the catatonia. Methods Case report and literature review. Results A 66-years-old woman admitted to the psychiatric ward with catatonia due to a depressive episode presented bilateral PE. Clinically stable, but still severely depressed after a trial of antidepressants, she was treated with ECT in the course of full anticoagulation with enoxaparin. After five ECT sessions, her mood was significantly better and she was walking and eating spontaneously. She did not present complications related either to PE or to anticoagulation. After the eighth ECT session, she evolved with hypomania, which was managed with oral medication adjustments. The patient was completely euthymic at discharge. Conclusion The case we presented provides further evidence to the anecdotal case reports on the safety of ECT in the course of concomitant full anticoagulant therapy after PE, and illustrates how, with the proper precautions, the benefits of ECT in such condition might outweigh its risks.

Assessing treatment response to prophylactic lithium use in patients with bipolar disorder

ABSTRACT Objetive To identify potential clinical and epidemiological predictors of long-term response to lithium treatment. Methods A total of 40 adult outpatients followed in an university hospital, with confirmed diagnosis of bipolar disorder and with history of lithium use for at least a six months period, had their response to this medication assessed through the use of a standardized instrument. The ALDA scale is based on retrospective clinical data, in our study assessed through a thoroughly reviewed of the medical charts, and is used to evaluate the clinical improvement with the treatment (Criterion A), corrected by the acknowledgement of possible confounding factors, such as duration of the treatment, compliance and concomitant use of additional medications (Criterion B), in order to estimate the response that can be specifically attributable to lithium. Results Our study found an inverse relation between the number of mood episodes with psychotic symptoms and lithium treatment outcome. Conclusion The results reinforce the hypothesis that lithium seems to be less efficacious in patients with bipolar disorder who present psychotic symptoms.

Therapeutic approach to patients complaining of high blood pressure in a cardiological emergency room

OBJECTIVE: To evaluate the management of patients complaining of high blood pressure (BP) in a cardiological emergency room. METHODS: Patients referred to the cardiological emergency room with the main complaint of high blood pressure were consecutively selected. The prescriptions and the choice of antihypertensive drugs were assessed. The classification of these patients as hypertensive emergencies or pseudoemergencies, according to the physician who provided initial care, was recorded. RESULTS: From a total of 858 patients presenting to the emergency room, 80 (9.3%) complained of high BP, and 61 (76.3%) received antihypertensive drugs. Sublingual nifedipine was the most commonly used drug (59%). One patient received intravenous medication, one patient was hospitalized and 6 patients (7.5%) were classified as hypertensive emergencies or pseudoemergencies. CONCLUSION: High BP could seldom be classified as a hypertensive emergency or pseudoemergency, even though it was a frequent complaint (9.3% of visits). Currently, the therapeutic approach is not recommended, even in specialized clinics.

Effects of carvedilol in heart failure due to dilated cardiomyopathy. Results of a double-blind randomized placebo-controlled study (CARIBE study)

OBJECTIVE: To assess the effects of carvedilol in patients with idiopathic dilated cardiomyopathy. METHODS: In a double-blind randomized placebo-controlled study, 30 patients (7 women) with functional class II and III heart failure were assessed. Their ages ranged from 28 to 66 years (mean of 43±9 years), and their left ventricular ejection fraction varied from 8% to 35%. Carvedilol was added to the usual therapy of 20 patients; placebo was added to the usual therapy of 10 patients. The initial dose of carvedilol was 12.5 mg, which was increased weekly until it reached 75 mg/day, according to the patient's tolerance. Clinical assessment, electrocardiogram, echocardiogram, and radionuclide ventriculography were performed in the pretreatment phase, being repeated after 2 and 6 months of medication use. RESULTS: A reduction in heart rate (p=0.016) as well as an increase in left ventricular shortening fraction (p=0.02) and in left ventricular ejection fraction (p=0.017) occurred in the group using carvedilol as compared with that using placebo. CONCLUSION: Carvedilol added to the usual therapy for heart failure resulted in better heart function.

PANDORA - Survey of Brazilian cardiologists about cholesterol reduction

OBJECTIVE: To report about a group of physicians' understanding of the recommendations of the II Brazilian Guidelines Conference on Dyslipidemias, and about the state of the art of primary and secondary prevention of atherosclerosis. METHODS: Through the use of a questionnaire on dyslipidemia, atherosclerosis prevention, and recommendations for lipid targets established by the II Brazilian Guidelines Conference on Dyslipidemias, 746 physicians, 98% cardiologists, were evaluated. RESULTS:Eighty-seven percent of the respondents stated that the treatment of dyslipidemia changes the natural history of coronary disease. Although most of the participants followed the total cholesterol recommendations (<200mg/dL for atherosclerosis prevention), only 55.8% would adopt the target of LDL-C <100 mg/dL for secondary prevention. Between 30.5 and 36.7% answered, in different questions, that the recommended level for HDL-C should be <35mg/dL. Only 32.7% would treat their patients indefinitely with lipid- lowering drugs. If the drug treatment did not reach the proposed target, only 35.5% would increase the dosage, and 29.4% would change the medication. Participants did not know the targets proposed for diabetics. CONCLUSION: Although the participating physicians valued the role played by lipids in the prevention of atherosclerosis, serious deficiencies exist in their knowledge of the recommendations given during the II Brazilian Guidelines Conference on Dyslipidemias.

Effects of losartan on ventricular remodeling in experimental infarction in rats

OBJECTIVE: To evaluate the effects of losartan on ventricular remodeling and on survival after myocardial infarction in rats. METHODS: After surgical occlusion of left coronary artery, 84 surviving male Wistar rats were divided into two groups: LO treated with losartan (20mg/kg/day, n=33) and NT (n=51), without medication. After 3 months, we analyzed mortality; ventricular to body mass ratio (VM /BM); myocardial hydroxyproline concentration (HOP); isovolumetric pressure, +dp/dt, -dp/dt, and diastolic volume/left ventricle mass ratio (VO/LV). RESULTS: Mortality was: LO = 22%, and NT = 47% (p<0.05). Ventricular mass,(VM/BM, mg/g) was 4.14 ± 0.76 and 3.54±0.48, in the NT and LO groups, respectively (p<0.05). HOP (median) was 4.92 upsilong/mg in the LO and 5.54 upsilong/g in the NT group (p>0.05). The V0/LV values (median) were 0.24 mL/g in group LO and 0.31 mL/g in group NT (p<0.05) compared to NT group. There were no differences between the groups for +dp/dt and -dp/dt parameters. CONCLUSION: 1- The use of losartan myocardial infarction causes an attenuation of ventricular remodeling, bringing about an increased survival, an attenuation of ventricular hypertrophy and dilation, and an improvement of the isovolumetric pressure; 2- the treatment does not modify the myocardial collagen concentration.

Immunologic evaluation in infective endocarditis

OBJECTIVE: To analyze the immune response in peripheral blood of patients with infective endocarditis. METHODS: We studied 10 patients with infective endocarditis, age range from 20 to 50 years-old, males and females, and 20 healthy subjects in the same age range. The diagnosis of the disease was based on the clinical picture, echocardiogram, and hemoculture based upon samples drawn and tested before the treatment started. The were no history of atopy or malnutrition, no autoimmune disease, and they were not using any immunosuppressant or antibiotic medication. RESULTS: The patients with endocarditis had significantly higher T and B lymphocyte, CD4+ and CD8+ cell counts, IgM and IgG serum levels, and C4 component of the complement than the control group; no significant difference concerning serum IgA and neutrophil oxidative metabolism; a significant decrease in C3, chemotaxis, and monocyte phagocytosis;cryoglobulins were detected in 66.6% of patients and they were formed by IgG, IgM, IgA, C3, and C4. CONCLUSION: The patients with infective endocarditis were immunocompetent in most sectors of immune response and, at a certain moment, an autoimmune component may be present.

Prescription and adherence to statins of patients with coronary artery disease and hypercholesterolemia

OBJECTIVE: Statins have proved to be safe and effective in the secondary prevention of coronary artery disease, but the level of prescription and the reasons for nonadherence to treatment in many coronariopathy treatment centers has not been determined. The purpose of this study was to identify reasons for nonadherence to statin therapy. METHODS: We analyzed 207 consecutive patients with coronary artery disease and hypercholesterolemia (total cholesterol > or = 200mg/dL or LDL - cholesterol > or = 130mg/dL). Patients' average age was 61.7±10 year; 111 (53.6%) male were and 94 (46.6%) were female. We analyzed the level of prescription and adherence to treatment with statins. RESULTS: Statins were prescribed for 139 (67%) patients, but only 85 (41%) used the drug. In spite of being indicated, statins were not prescribed in 68 (33%) patients. Of 54 (26%) patients, nonadherent to statins, 67% did not use the drug due to its high cost, 31% due to the lack of instruction, and only 2% due to side effects. Total cholesterol (260.3±42.2 vs 226.4±51.9; p<0.0001) and LDL cholesterol (174.6±38.1 vs 149.6±36.1; p<0.0001) were lower in patients on medication. HDL-cholesterol increased from 37.6±9.6 to 41.5±12.9mg/dL (p=0.02), and triglycerides were not modified in patients using statins. CONCLUSION: The prescription of statins in patients with coronary artery disease and dyslipidemia is high; however, its adherence is far from satisfactory, due to the high cost of the medication. Reduction in total cholesterol and LDL cholesterol levels did not reach the targets recommended by the Brazilian Consensus on Dyslipidemia.

Reliability of the information about the history of diagnosis and treatment of hypertension. Differences in regard to sex, age, and educational level. The pró-saúde study

OBJECTIVE: To assess the intraobserver reliability of the information about the history of diagnosis and treatment of hypertension. METHODS: A multidimensional health questionnaire, which was filled out by the interviewees, was applied twice with an interval of 2 weeks, in July '99, to 192 employees of the University of the State of Rio de Janeiro (UERJ), stratified by sex, age, and educational level. The intraobserver reliability of the answers provided was estimated by the kappa statistic and by the coefficient of intraclass correlation (CICC). RESULTS: The general kappa (k) statistic was 0.75 (95% CI=0.73-0.77). Reliability was higher among females (k=0.88, 95% CI=0.85-0.91) than among males (k=0.62, 95% CI=0.59-0.65).The reliability was higher among individuals 40 years of age or older (k=0.79; 95% CI=0.73-0.84) than those from 18 to 39 years (k=0.52; 95% CI=0.45-0.57). Finally, the kappa statistic was higher among individuals with a university educational level (k=0.86; 95% CI=0.81-0.91) than among those with high school educational level (k=0.61; 95% CI=0.53-0.70) or those with middle school educational level (k=0.68; 95% CI=0.64-0.72). The coefficient of intraclass correlation estimated by the intraobserver agreement in regard to age at the time of the diagnosis of hypertension was 0.74. A perfect agreement between the 2 answers (k=1.00) was observed for 22 interviewees who reported prior prescription of antihypertensive medication. CONCLUSION: In the population studied, estimates of the reliability of the history of medical diagnosis of hypertension and its treatment ranged from substantial to almost perfect reliability.
