RESUMEN

Considerable variation in clozapine utilization exists across the United States, and little is known about the perspective of psychiatrists in states with low clozapine use. To better understand clozapine practices, attitudes, and barriers, a survey was administered to a group of southeastern state conference attendees (SSCA; N = 86). The same survey was administered to psychiatrists belonging to a national community psychiatry organization (AACP; N = 57), and differences were analyzed across the two samples. In comparison to the AACP, the SSCA group felt less comfortable, perceived clozapine as less safe and effective, had fewer patients on clozapine, and were more likely to prefer antipsychotic polypharmacy to clozapine use. Across the sample, use of a myocarditis screening protocol was rare (N = 14/76; 18%) and less than half used plasma antipsychotic levels to guide dosage (N = 60/129; 47%). Continuing professional education on clozapine are needed for psychiatrists who see individuals with psychotic disorders.

RESUMEN

Despite its unique efficacy, clozapine remains underutilized in the United States. Perceptions about clozapine and barriers to its use have been examined among prescribers, but insufficiently studied among consumers. We surveyed 211 antipsychotic consumers (86 on clozapine and 125 on other antipsychotics) on their medication-related perspectives in a public hospital system in Atlanta, Georgia, USA. In contrast to their previous regimen, 72% of clozapine consumers reported they were more satisfied with clozapine. When compared with consumers taking other antipsychotics, clozapine consumers reported more side effects but did not differ on other measures of satisfaction or efficacy. We found Caucasians to be overrepresented among clozapine, as compared to other antipsychotic consumers. Side effects most strongly associated with poor safety ratings were sedation, limb jerking, and dizziness when standing. However, clozapine was only rated less safe by consumers who experienced more than one of these side effects. We used an unsupervised clustering approach to identify three major groups of clozapine consumers. Cluster A (19%) had the lowest safety ratings, aversion to blood work, and a high rate of side effects that associate with lower safety ratings. Cluster B (25%) experienced more hospitalizations and reported satisfaction with clozapine that correlated with efficacy ratings, irrespective of safety ratings. Cluster C (56%) experienced fewer hospitalizations, fewer previous drug trials, greater educational attainment, lower rates of smoking, and rated clozapine more highly. This work identifies common side effects that influence the subjective safety of clozapine and suggests that attitudes toward clozapine depend on context-specific factors.

RESUMEN

BACKGROUND: Bipolar Affective Disorder (BPAD) accounts for 10-25% of all mood disorders in the geriatric population and 5% of all inpatient admissions to geropsychiatric units. Electroconvulsive therapy (ECT) is an effective treatment for all phases of BPAD, though only a few studies have focused on BPAD in the geriatric population. This study examines the safety and efficacy of ultra-brief right unilateral (UBRUL) ECT for patients with late-life bipolar depression (BD). METHODS: A retrospective chart review was conducted of patients with late-life BD who received UBRUL ECT treatments. Symptomatic response was measured using pre- and post-ECT Quick Inventory of Depressive Symptomatology (QIDS-SR16) and Beck Depression Inventory (BDI-II) scores. Clinical improvement and cognitive change were measured using Clinical Global Impression-Improvement (CGI-I) and Electroconvulsive Cognitive Assessment (ECCA) scores. RESULTS: Twenty-Seven elderly patients (mean age 69.1 ± 7.7 years) were included in the analysis. Baseline QIDS-SR16 was 17.3 ± 5.3 and BDI-II 30.0 ± 9.2. 80.0% (16/20) and 57.1% (4/7) of patients achieved response (50.0% decline) in their QIDS-SR16 and BDI-II scores, respectively. Remission rates in QIDS-SR16 (post-ECT scores ≤5) and BDI-II (post-ECT scores ≤12) were 65.0% (13/20) and 42.9% (3/7), respectively. Mean QIDS-SR16 and BDI-II scores were reduced by a statistically significant 68.2% and 50.5%, respectively (two-tailed, paired p-values <0.01) after ECT. CGI-I of ≤2 was attained by 85.2% (23/27) of patients. 85.7% (12/14) of patients saw no change or improvement in ECCA scores. LIMITATIONS: Inherent complications of chart review regarding quality, availability, and homogeny of data. CONCLUSIONS: UBRUL ECT is a safe and effective treatment for patients presenting with late-life BD.

RESUMEN

BACKGROUND: Recent evidence suggests that biologic therapy with targeted activity within the Type 2 inflammatory pathway can improve the clinical signs and symptoms of chronic rhinosinusitis with nasal polyposis (CRSwNP). There remains a population in CRSwNP that despite medical therapy and endoscopic sinus surgery have persistent signs and symptoms of disease. Therefore, biologics, monoclonal antibody agents, could be beneficial therapeutic treatments for these patients. There have been eight randomized, double-blind, placebo-controlled trails performed for CRSwNP targeted components of the Type 2 inflammatory pathway, notably interleukin (IL)-4, IL-5 and IL-13, IL-5R, IL-33, and immunoglobulin (Ig)E. However, there are no formal recommendations for the optimal use of biologics in managing Chronic Rhinosinusitis (CRS) within the Canadian health care environment. METHODS: A Delphi Method process was utilized involving three rounds of questionnaires in which the first two were completed individually online and the third was discussed on a virtual platform with all the panelists. 17 fellowship trained rhinologists across Canada evaluated the 28 original statements on a scale of 1-10 and provided comments. A rating within 1-3 indicated disagreement, 8-10 demonstrated agreement and 4-7 represented being neutral towards a statement. All ratings were quantitively reviewed by mean, median, mode, range and standard deviation. Consensus was defined by removing the highest and lowest of the scores and using the "3 point relaxed system". RESULTS: After three rounds, a total of 11 statements achieved consensus. This white paper only contains the final agreed upon statements and clear rationale and support for the statements regarding the use of biologics in patients with CRS. CONCLUSION: This white paper provides guidance to Canadian physicians on the use of biologic therapy for the management of patients with CRS, but the medical and surgical regimen should ultimately be individualized to the patient. As more biologics become available and additional trials are published we will provide updated versions of this white paper every few years.

RESUMEN

Parkinson disease (PD) is a debilitating neurological condition that includes both motor symptoms and nonmotor symptoms (NMS). Psychiatric complaints comprise NMS and are collectively referred to as neuropsychiatric manifestations. Common findings include atypical depressive symptoms, anxiety, psychosis, impulse control disorder, deterioration of cognition, and sleep disturbances. Quality of life (QoL) of patients suffering from NMS is greatly impacted and many times can be more debilitating than motor symptoms of PD. We expand on knowledge gained from treatment models within a comprehensive care model that incorporates multidisciplinary specialists working alongside psychiatrists to treat PD. Insight into background, clinical presentations, and treatment options for patients suffering from neuropsychiatric manifestations of PD are discussed. Identifying symptoms early can help improve QoL, provide early symptom relief, and can assist tailoring treatment plans that limit neuropsychiatric manifestations.

RESUMEN

Electroconvulsive therapy (ECT) is an effective treatment for severe psychiatric disorders. Patients referred to ECT are often taking multiple medications, many of which can potentially affect the safety and efficacy of their course of ECT. This review evaluates the impact of a variety of psychotropic medications often used in conjunction with ECT and examines strategies to optimize their management. The review encompasses mood stabilizers, antidepressants, benzodiazepines, antiepileptics, antipsychotics, and other commonly used psychotropics.

RESUMEN

BACKGROUND: Electroconvulsive therapy (ECT) is a well-established treatment for severe depression but may result in adverse cognitive effects. Available cognitive screening instruments are nonspecific to the cognitive deficits associated with ECT. An ECT-cognitive assessment tool which can be easily administered was developed and validated in a clinical setting. METHODS: One hundred and thirty-six participants were enrolled. The ElectroConvulsive therapy Cognitive Assessment (ECCA) and the Montreal Cognitive Assessment (MoCA) were administered prospectively to 55 participants with major depressive disorder (MDD) undergoing ECT at three time points: pre-treatment, before the sixth treatment and one-week post-treatment. The psychometric properties of the total and domain scores were evaluated at all three time points. Forty demographically comparable participants with MDD who did not receive ECT, and 41 healthy, age-matched controls were evaluated at a single time point. RESULTS: ECCA and MoCA scores were not statistically different at baseline. Prior to the sixth and final ECT session, total ECCA scores were significantly lower than the MoCA total scores. The ECCA domains of subjective memory, informant-assessed memory, attention, autobiographical memory and delayed verbal recall were significantly lower post-ECT compared to pre-ECT. LIMITATIONS: The ECCA was compared only to the MoCA rather than to a more comprehensive neuropsychological testing. This limitation reflected the real-life clinical burden of performing full neuropsychological testing at three time points during the treatment course. CONCLUSIONS: The ECCA is a brief, reliable, bedside cognitive screening assessment tool that may be useful to monitor cognitive function in patients treated with ECT. The test can be downloaded from fuquacenter.org/ecca.

RESUMEN

OBJECTIVE: Much of the functional disturbance in patients with dementia reflects the presence of noncognitive behavioral and psychological symptoms of dementia (BPSD). Agitation is among the most distressing symptoms for patients, clinicians, and caregivers. Currently no pharmacotherapy has clearly been shown to be of value for this condition. This study used a chart review method to examine the safety and efficacy of electroconvulsive therapy (ECT) for patients with dementia receiving ECT for agitation. METHODS: A retrospective chart review was conducted of patients with dementia presenting with symptoms of aggression or agitation and who received ECT treatments. Aggression and agitation were measured by pre- and post-ECT Pittsburg Agitation Scale (PAS) scores. Detailed history of the use of psychotropic medications as well as other clinically relevant variables was analyzed. FINDINGS: Sixty elderly patients (45 women and 15 men, 75% female, mean age 77.5 ± 8.0 years) were included in the analysis. Most patients were treatment resistant to multiple psychotropic medications prior to ECT (mean number 6.1±1.5). The baseline PAS total was 9.3 ± 3.7 and it decreased significantly after three (2.5±2.8) and six (1.5±2.3) ECT treatments. No significant ECT-related medical complications were observed except transient confusion. A decrease in the number of psychotropics prescribed along with an increase in the GAF score was observed after the ECT treatment course. CONCLUSION: ECT was safe in this sample of patients who had co-morbid medical conditions. ECT was associated with the following observations: 1) a reduction in agitation; 2) a reduction in psychotropic polypharmacy; and 3) an improvement in global functioning level. Further research evaluating the effects of ECT in the setting of dementia is warranted.

RESUMEN

We conducted a cross-sectional survey including specialist trainees in obstetrics and gynaecology in the Health Education West Midlands region, UK, to capture their views and assess training opportunities on the use of Kielland's forceps. Half of the trainees in the region completed the survey (87/172, 50%). Only 31% of our trainees worked in units that supported the training on these forceps (27/87, 31%). The majority reported that they did not get enough exposure to using Kielland's forceps (53/87, 60.9%). Only a minority (5.7%, 5/87) felt confident to perform a Kielland's rotational delivery independently. The majority (64.3%, 56/87) were keen to continue using Kielland's forceps in the future if competent. More than two-thirds (86.2%, 75/87) felt that simulation could aid their training. There was large enthusiasm for training on the safe use of Kielland's forceps among trainees in obstetrics and gynaecology in the West Midlands region. A national assessment of training resources is needed to better plan training recourses on this complex skill.

RESUMEN

A major medical problem for patients undergoing electroconvulsive therapy (ECT) is the occurrence of postictal agitation (PIA). This phenomenon is associated with confusion and disorientation that can have severe clinical implications for the safety of the patient and health care professionals. Many different pharmacological strategies have been used to prevent PIA. We present data on 40 patients who suffered from PIA after a course of ECT and evaluate the prophylactic use of orally disintegrating olanzapine in the prevention of PIA in subsequent ECT treatments.

RESUMEN

Our team at Emory University Hospital contacted experts at the National Network of Depression Centers (NNDC) for clinical guidance concerning a patient with schizophrenia hospitalized in the intensive care unit with a complex case of prolonged delirium secondary to neuroleptic malignant syndrome (NMS). Through the NNDC, leading psychiatrists across the United States with expertise in electroconvulsive therapy (ECT) provided us with treatment strategies based on experience in our area of concern. This report describes our use of ECT to treat severe NMS in this patient with schizophrenia, utilizing the recommendations made by the NNDC's ECT experts concerning electrode position, number and frequency of treatments, and selection of anesthetic induction agents. This case report highlights the utility of expert consultation in the treatment of rare diseases and provides guidance on how to treat NMS in the intensive care unit setting.

RESUMEN

Lithium is a mood stabilizer rarely associated with drug-induced parkinsonism (DIP). We present a case of an elderly woman with bipolar disorder who developed parkinsonian symptoms after chronic lithium administration despite therapeutic serum levels. Upon evaluation, classic parkinsonian signs of muscle rigidity, tremor, bradykinesia, freezing of gait, and cognitive decline were observed. Initially, she was diagnosed with Parkinson's disease (PD); however, DaTscan SPECT imaging clarified the diagnosis as DIP. As the daily lithium dosage was reduced, the patient's motor symptoms improved. This report emphasizes close monitoring of lithium levels in geriatric populations and the need to consider lithium-induced parkinsonism when PD symptoms appear in chronic lithium users.

RESUMEN

BACKGROUND: Unilateral sudden sensorineural hearing loss due to an infarct in the vertebrobasilar system has been widely reported. Most patients have a background of traditional coronary risk factors related to these cerebrovascular episodes. CASE REPORT: A 32-year-old male, a regular user of anabolic steroids, presented to the emergency department with unilateral sensorineural hearing loss and symptoms suggestive of an infarct of the anterior inferior cerebellar artery but in the absence of risk factors for ischaemic stroke. RESULTS: Magnetic resonance imaging confirmed the presence of infarction in the region supplied by the anterior inferior cerebellar artery. Polycythaemia was found on haematological analysis, which we believe was secondary to the use of anabolic steroids. The patient was commenced on aspirin as per the stroke management protocol. There was resolution of neurological symptomatology six weeks after the episode, but no improvement in hearing. CONCLUSION: To our knowledge, this is the first case report of unilateral sensorineural hearing loss secondary to the use of anabolic steroids causing polycythaemia. This cause should be considered in the differential diagnosis of patients presenting with sensorineural hearing loss, especially in young males, when no other risk factors can be identified.

RESUMEN

Malaria transmission is unstable in Pakistan with the highest number of cases reported during the monsoon season. Despite its high incidence, malaria is still a poorly resourced, poorly funded and an uncontrolled disease especially in far-flung areas. Pakistan's National Malaria Control Program (NMCP), although operational since its inception in 1947, has suffered due to the unstable political, socioeconomic and financial situation prevalent in the country. In Pakistan, more than 300 000 cases of malaria are reported every year with 68% of the cases caused by Plasmodium vivax. It is estimated that about 70-80% of the population accesses the private sector for treatment. As the private sector does not routinely report data to the government, the actual malaria burden could be 4-5 times higher than reported. P. vivax now accounts for more than 85% of all cases requiring hospital admission compared to 54% in 2000. In this review, we have described the saga of poor control of malaria in Pakistan over several years in context of restructuring of the Malaria Control Program, challenges to improvement, and way forward.

RESUMEN

AIM: Many patients having anterior resection for rectal cancer suffer from severe long-term bowel dysfunction, known as low anterior resection syndrome (LARS). The LARS score was developed in Denmark, and Swedish, Spanish and German versions have been validated. The aim of this study was to validate the English translation of the LARS score in British rectal cancer patients. METHOD: Rectal cancer patients who underwent an anterior resection in 12 UK centres received the LARS score questionnaire, the EORTC QLQ-C30 and a single ad hoc quality of life question. A subgroup of patients received the LARS score questionnaire twice. RESULTS: The response rate was 80% and 451 patients were included in the analyses. A strong association between LARS score and quality of life (convergent validity) was found (P < 0.01), discriminative validity was good (P < 0.02) and the test-retest reliability was high (intraclass correlation coefficient 0.83). CONCLUSION: The English translation of the LARS score has shown good psychometric properties comparable with recently published results from an international multicentre study. Thus, the English translation of the LARS score can be considered a valid and reliable tool for measuring LARS.

RESUMEN

RATIONALE: Low circulating progenitor cell numbers and activity may reflect impaired intrinsic regenerative/reparative potential, but it remains uncertain whether this translates into a worse prognosis. OBJECTIVES: To investigate whether low numbers of progenitor cells associate with a greater risk of mortality in a population at high cardiovascular risk. METHODS AND RESULTS: Patients undergoing coronary angiography were recruited into 2 cohorts (1, n=502 and 2, n=403) over separate time periods. Progenitor cells were enumerated by flow cytometry as CD45(med+) blood mononuclear cells expressing CD34, with additional quantification of subsets coexpressing CD133, vascular endothelial growth factor receptor 2, and chemokine (C-X-C motif) receptor 4. Coefficient of variation for CD34 cells was 2.9% and 4.8%, 21.6% and 6.5% for the respective subsets. Each cohort was followed for a mean of 2.7 and 1.2 years, respectively, for the primary end point of all-cause death. There was an inverse association between CD34(+) and CD34(+)/CD133(+) cell counts and risk of death in cohort 1 (ß=-0.92, P=0.043 and ß=-1.64, P=0.019, respectively) that was confirmed in cohort 2 (ß=-1.25, P=0.020 and ß=-1.81, P=0.015, respectively). Covariate-adjusted hazard ratios in the pooled cohort (n=905) were 3.54 (1.67-7.50) and 2.46 (1.18-5.13), respectively. CD34(+)/CD133(+) cell counts improved risk prediction metrics beyond standard risk factors. CONCLUSIONS: Reduced circulating progenitor cell counts, identified primarily as CD34(+) mononuclear cells or its subset expressing CD133, are associated with risk of death in individuals with coronary artery disease, suggesting that impaired endogenous regenerative capacity is associated with increased mortality. These findings have implications for biological understanding, risk prediction, and cell selection for cell-based therapies.

RESUMEN

AIM: Adenocarcinoma of the lower rectum is clinically challenging because of the need to choose between a wide excision to achieve oncological clearance, on the one hand, and sphincter conservation to maintain anal function, on the other. The English National Low Rectal Cancer Development Programme (LOREC) was developed under the auspices of the Association of Coloproctology of Great Britain and Ireland and the English National Cancer Action Team to improve the outcome of low rectal cancer in England. METHOD: LOREC was initiated focusing on preoperative imaging, selective neoadjuvant therapy, optimal surgical treatment and detailed pathological assessment of the excised specimen. Its key elements were 1-day multidisciplinary team (MDT) workshops, cadaveric surgical training, surgical mentoring, pathological audit and radiological workshops. RESULTS: Overall, 147 (89.6%) of 164 MDTs from 151 National Health Service (NHS) Trusts (some with two MDTs) in England participated in 15 workshops in Basingstoke or Leeds. In addition, 112 surgeons attended a 1-day cadaveric training programme in Bristol, Newcastle or Nottingham, with the main focus on extralevator abdominoperineal excision and pelvic reconstruction, with input from anatomists and from colorectal and plastic surgeons. CONCLUSION: Optimal staging, selective preoperative chemoradiotherapy and precise surgery were considered as crucial to improve the outcome for patients with low rectal cancer.

RESUMEN

INTRODUCTION: Port site hernia is an important yet under-recognised complication of laparoscopic surgery, which carries a high risk of strangulation due to the small size of the defect involved. The purpose of this study was to examine the incidence, classification, and pathogenesis of this complication, and to evaluate strategies to prevent and treat it. METHODS: Medline was searched using the words "port site hernia", "laparoscopic port hernia" "laparoscopic complications" and "trocar site hernias". The search was limited to articles on cholecystectomy, colorectal, bariatric or anti-reflux surgery published in English. A total of 42 articles were analysed and of these 35 were deemed eligible for review. Inclusion criteria were laparoscopic gastrointestinal surgery in English only with reported incidence of port site herniation. Studies were excluded if insufficient data was provided. Eligible studies were also cross-referenced. RESULTS: Analysis of 11,699 patients undergoing laparoscopic gastrointestinal procedures demonstrated an incidence of port site hernias of 0.74% with a mean follow-up of 23.9 months. The lowest incidence of port site herniation was for bariatric surgery with 0.57% in 2644 patients with a mean follow-up of 67.4 months while the highest incidence was for laparoscopic colorectal surgery with an incidence of 1.47% in 477 patients with a mean follow-up of 71.5 months. CONCLUSION: All fascial defects larger than or equal to 10mm should be closed with peritoneum, while smaller defects may require closure in certain circumstances to prevent herniation. Laparoscopic port site herniation is a completely preventable cause of morbidity that requires a second surgical procedure to repair.
