Psychosis associated with methimazole-induced hypothyroidism: a case report

INTRODUCTION: Thyroid dysfunction has often been associated with several psychiatric manifestations. Previous case reports/series suggest the possible role played by acute alteration of thyroid status in the onset of psychotic symptoms. METHODS: Case report and literature review. RESULTS: A 45-year-old woman with no psychiatric antecedents was brought to the ER with a full-blown psychotic episode, marked by paranoid delusions, which developed gradually over two months. She had been treated elsewhere for hyperthyroidism for five years with methimazole 40 mg/d, with poor compliance. One month before the beginning of the psychotic symptoms, methimazole was raised to 60 mg/d and she started taking it correctly. Five months earlier she had TSH: 0.074 uUI/ml and free T4: 1.3 ng/dl. At admission we found a diffuse thyroid goiter, TSH: 70.9 uUI/ml and free T4: 0.03 ng/dl. Brain CT was normal. We hospitalized her with the diagnosis of a psychosis secondary to hypothyroidism, suspended methimazole, and gave her levothyroxine (up to 75 µg/d) and risperidone (2 mg/d). The patient had a quick remission and was discharged after 15 days. Within one month she had TSH: 0.7 uUI/ml and was completely recovered psychiatrically. She has been well since then, with risperidone in the first 8 months, and without it for 10 months now. CONCLUSION: This case report is a reminder of the necessity of checking thyroid status as part of clinical assessment of psychoses. It also supports the hypothesis that antithyroid drugs may have severe psychiatric consequences, especially when they lead to an acute change of thyroid status.

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.

Extensive subcutaneous emphysema as a presentation of ischemic colitis

Introduction . Subcutaneous emphysema is usually benign and self-limited; however, it may be associated with a life-threating situation. Case Report . An elderly woman with progressive malaise with extensive subcutaneous emphysema (cervical to abdominal wall) was observed at the emergency department. Colonic perforation was diagnosed and the patient underwent surgery. Intraoperatively, necrosis and perforation of the sigmoid colon into the retroperitoneum were found and a Hartmann procedure was performed. Conclusion . Cervical and thoracic subcutaneous emphysema may be the first sign of intra-abdominal lesion.

Hematoma retroesofágico com grave disfagia após estreptoquinase para tratamento da trombose venosa axilo-subclávia

Homem de 72 anos, portador de neoplasia de próstata estádio IV, submetido à osteossíntese da coluna cervical para descompressão metastática da raiz nervosa, responsável por dor intensa no membro superior direito. Após três meses da internação, apresentou trombose total da veia axilo-subclávia direita, complicação da cateterização prolongada da veia subclávia direita para controle de septicemia secundária a pneumonia hospitalar. Foi submetido a terapia trombolítica com estreptoquinase por via venosa, no membro superior contra-lateral, na dose de 250.000UI em 15min, seguida de 100.000UI/h durante cinco dias, com total recanalização do trombo e redução do edema. Após 24h do término da trombólise, apresentou disfagia a líquidos e o esofagograma mostrou extensa compressão extrínseca do esôfago, por provável hematoma retroesofágico. Necessitou de nutrição enteral durante três meses, quando ocorreu normalização da deglutição, reabsorção do hematoma retroesofágico e passagem adequada do contraste pelo esôfago. No seguimento evolutivo não apresentou seqüelas da trombose venosa profunda, não tem disfagia e permaneceu em uso profilático de meias elásticas e heparina de baixo peso molecular.

Cholinergic stimulation with pyridostigmine, hemodynamic and echocardiographic analysis in healthy subjects

OBJECTIVE: Growing evidence suggests that sudden death after an acute myocardial infarction (AMI) correlates with autonomic nervous system imbalance. Parasympathomimetic drugs have been tested to reverse these changes. However, their effects on ventricular function need specific evaluation. Our objective was to analyze pyridostigmine's (PYR) effect on hemodynamic and echocardiographic variables of ventricular function. METHODS: Twenty healthy volunteers underwent Doppler echocardiographic evaluations, blood pressure (BP), and heart rate (HR) assessment at rest, before and 120 min after ingestion of 30 mg PYR or placebo, according to a double-blind, placebo-controlled, crossed and randomized protocol, on different days. RESULTS: PYR was well tolerated and did not cause alterations in BP or in ventricular systolic function. A reduction in HR of 10.9±1.3% occurred (p<0,00001). There was an A wave reduction in the mitral flow (p<0.01) and an E/A ratio increase (p<0.001) without changes in the other diastolic function parameters (p>0.05). CONCLUSION: PYR reduces HR and increases E/A ratio, without hemodynamic impairment or ventricular function change.

Right ventricular bifocal stimulation in the treatment of dilated cardiomyopathy with heart failure

OBJECTIVE: To describe a new more efficient method of endocardial cardiac stimulation, which produces a narrower QRS without using the coronary sinus or cardiac veins. METHODS: We studied 5 patients with severe dilated cardiomyopathy, chronic atrial fibrillation and AV block, who underwent definitive endocardial pacemaker implantation, with 2 leads, in the RV, one in the apex and the other in the interventricular septum (sub pulmonary), connected, respectively, to ventricular and atrial bicameral pacemaker outputs. Using Doppler echocardiography, we compared, in the same patient, conventional (VVI), high septal ("AAI") and bifocal ("DDT" with AV interval ~ 0) stimulation. RESULTS: The RV bifocal stimulation had the best results with an increase in ejection fraction and cardiac output and reduction in QRS duration, mitral regurgitation and in the left atrium area (p <= 0.01). The conventional method of stimulation showed the worst result. CONCLUSION: These results suggest that, when left ventricular stimulation is not possible, right ventricular bifocal stimulation should be used in patients with severe cardiomyopathy where a pacemaker is indicated.

Reduction of QTc interval dispersion. Potential mechanism of cardiac protection of pyridostigmine bromide

OBJECTIVE: Parasympathetic dysfunction is an independent risk factor in individuals with coronary artery disease, and cholinergic stimulation is a potential therapeutical option. We determined the effects of pyridostigmine bromide, a reversible anticholinesterase agent, on electrocardiographic variables of healthy individuals. METHODS: We carried out a cross-sectional, double blind, randomized, placebo-controlled study. We obtained electrocardiographic tracings in 12 simultaneous leads of 10 healthy young individuals at rest before and after oral administration of 45 mg of pyridostigmine or placebo. RESULTS: Pyridostigmine increased RR intervals (before: 886±27 ms vs after: 1054±37 ms) and decreased QTc dispersion (before: 72±9ms vs after: 45±3ms), without changing other electrocardiographic variables (PR segment, QT interval, QTc, and QT dispersion). CONCLUSION: Bradycardia and the reduction in QTc dispersion induced by pyridostigmine may effectively represent a protective mechanism if these results can be reproduced in individuals with cardiovascular diseases.
