The Study of Education Effect on Knowledge of, and Attitudes Toward Electroconvulsive Therapy Among Iranian Nurses and Patients’ Relatives in a Psychiatric Hospital, 2009-2010

AbstractElectroconvulsive therapy (ECT) is a cost effective method in the treatment of some psychiatric disorders. Although, service users such as health providers and nurses, also patients and their relatives may refuse ECT when indicated, due to the myths and little or lack of knowledge about the procedure. The knowledge of and attitudes toward ECT among nurses, may reflect on patients and influence treatment choice. For doing this procedure relatives informed consent is necessary, so their knowledge of and attitude toward ECT is important for getting informed consent and following treatment sessions. Objective: This research was conducted as a quasi-experimental study to measure knowledge of and attitudes toward ECT in 2 groups: relatives and nursing. Also, to study the effect of education on knowledge of and attitudes toward ECT in 2 groups. Methods: In this research the pre and post test self – administered questionnaires were completed by 46 relatives and 46 nurses before and after education about ECT. Results: Nurses in this research received a mean score of X=34.97 knowledge before education and X=39.78 after education (t=2.02, p<0.05), and a mean score of X=33.41 attitude before education and, X=42.82 after education (t=-14.25, p<0.001). Relatives received a mean score of X=23.41 knowledge before education and X=30.15 after education (t=-12.44, p<0.001), and a mean score of X=33.39 attitude before education and, X=41.13 after education (t=-9.10, p<0.001). The differences between the 2 means among two groups were found to be statistically significant. Conclusion: Education given to nurses and relatives about ECT increased their knowledge of, and improved their attitudes toward ECT. For this reason it is recommended that continuing education about ECT process should be planned and given at regular intervals

Limitations of Tc99m-MIBI-SPECT Imaging Scans in Persistent Primary Hyperparathyroidism

In primary hyperparathyroidism (PHPT) the predictive value of technetium 99m sestamibi single emission computed tomography (Tc99m-MIBI-SPECT) for localizing pathological parathyroid glands before a first parathyroidectomy (PTx) is 83-100%. Data are scarce in patients undergoing reoperative parathyroidectomy for persistent hyperparathyroidism. The aim of the present study was to determine the value of Tc99m-MIBI-SPECT in localizing residual hyperactive parathyroid tissue in patients with persistent primary hyperparathyroidism (PHPT) after initial excision of one or more pathological glands. We retrospectively evaluated the localizing accuracy of Tc99m-MIBI-SPECT scans in 19 consecutive patients with persistent PHPT who had a scan before reoperative parathyroidectomy. We used as controls 23 patients with sporadic PHPT who had a scan before initial surgery. In patients with persistent PHPT, Tc99m-MIBI-SPECT accurately localized a pathological parathyroid gland in 33% of cases before reoperative parathyroidectomy, compared to 61% before first PTx for sporadic PHPT. The Tc99m-MIBI-SPECT scan accurately localized intra-thyroidal glands in 2 of 7 cases and a mediastinal gland in 1 of 3 cases either before initial or reoperative parathyroidectomy. Our data suggest that the accuracy of Tc99m-MIBI-SPECT in localizing residual hyperactive glands is significantly lower before reoperative parathyroidectomy for persistent PHPT than before initial surgery for sporadic PHPT. These findings should be taken in consideration in the preoperative workup of patients with persistent primary hyperparathyroidis

Recommendations for Diagnosis and Treatment of Pseudohypoparathyroidism and Related Disorders : An Updated Practical Tool for Physicians and Patients

Patients affected by pseudohypoparathyroidism (PHP) or related disorders are characterized by physical findings that may include brachydactyly, a short stature, a stocky build, early-onset obesity, ectopic ossifications, and neurodevelopmental deficits, as well as hormonal resistance most prominently to parathyroid hormone (PTH). In addition to these alterations, patients may develop other hormonal resistances, leading to overt or subclinical hypothyroidism, hypogonadism and growth hormone (GH) deficiency, impaired growth without measurable evidence for hormonal abnormalities, type 2 diabetes, and skeletal issues with potentially severe limitation of mobility. PHP and related disorders are primarily clinical diagnoses. Given the variability of the clinical, radiological, and biochemical presentation, establishment of the molecular diagnosis is of critical importance for patients. It facilitates management, including prevention of complications, screening and treatment of endocrine deficits, supportive measures, and appropriate genetic counselling. Based on the first international consensus statement for these disorders, this article provides an updated and ready-to-use tool to help physicians and patients outlining relevant interventions and their timing. A life-long coordinated and multidisciplinary approach is recommended, starting as far as possible in early infancy and continuing throughout adulthood with an appropriate and timely transition from pediatric to adult care.Peer reviewe

Diagnosis and management of pseudohypoparathyroidism and related disorders: first international Consensus Statement

This Consensus Statement covers recommendations for the diagnosis and management of patients with pseudohypoparathyroidism (PHP) and related disorders, which comprise metabolic disorders characterized by physical findings that variably include short bones, short stature, a stocky build, early-onset obesity and ectopic ossifications, as well as endocrine defects that often include resistance to parathyroid hormone (PTH) and TSH. The presentation and severity of PHP and its related disorders vary between affected individuals with considerable clinical and molecular overlap between the different types. A specific diagnosis is often delayed owing to lack of recognition of the syndrome and associated features. The participants in this Consensus Statement agreed that the diagnosis of PHP should be based on major criteria, including resistance to PTH, ectopic ossifications, brachydactyly and early-onset obesity. The clinical and laboratory diagnosis should be confirmed by a molecular genetic analysis. Patients should be screened at diagnosis and during follow-up for specific features, such as PTH resistance, TSH resistance, growth hormone deficiency, hypogonadism, skeletal deformities, oral health, weight gain, glucose intolerance or type 2 diabetes mellitus, and hypertension, as well as subcutaneous and/or deeper ectopic ossifications and neurocognitive impairment. Overall, a coordinated and multidisciplinary approach from infancy through adulthood, including a transition programme, should help us to improve the care of patients affected by these disorders

Burden of illness in patients with chronic hypoparathyroidism not adequately controlled with conventional therapy: a Belgium and the Netherlands survey.

PURPOSE: To determine the burden of illness in patients with not adequately controlled chronic hypoparathyroidism receiving conventional therapy in Belgium and the Netherlands. METHODS: Data were generated from a cross-sectional, two-part online survey where endocrinologists from both countries and nephrologists from Belgium were invited by phone to participate. Part 1 included collecting data on general management of patients with hypoparathyroidism. In Part 2, physicians were requested to provide data on one or two current cases of patients with chronic hypoparathyroidism not adequately controlled on conventional therapy. Data collected included aetiology of hypoparathyroidism, clinical manifestations, comorbidities, results of laboratory and other investigations used for diagnosis and screening for complications, therapy received, and physician's perception of impaired quality of life (QoL). RESULTS: Thirty-six endocrinologists and 29 nephrologists from Belgium and 28 endocrinologists from the Netherlands participated in the survey. Data included clinical symptoms, biochemical parameters, and QoL for 97 current patients with not adequately controlled chronic hypoparathyroidism on conventional therapy. Median duration of not adequately controlled hypoparathyroidism was 2.2 years, range 0.17-20.0. Most patients had neuromuscular (85%) and/or neurological (67%) symptoms, 71% had abnormal biochemical parameters, 10% were overweight, and physicians perceived that 71% had impaired QoL. Most frequently reported comorbidities included hypertension (25%), renal comorbidity (20%), diabetes mellitus (12%), and dyslipidaemia (11%). CONCLUSION: Patients with chronic hypoparathyroidism not adequately controlled on conventional therapy experience a substantial burden of illness, mainly due to persistence of symptoms and presence of multiple comorbidities

The flare in alkaline phosphatase activity post-orchidectomy predicts which patient may benefit from early chemotherapy in metastatic prostate cancer

BACKGROUND: A flare in serum alkaline phosphatase (ALP) activity post-orchidectomy has been shown to be of negative prognostic value for progression-free survival (PFS) in patients with prostate cancer. The aim of this study was to investigate whether a flare in ALP may help identify patients in whom prognosis could be positively influenced by early chemotherapy. METHODS: A retrospective analysis of the database of a Dutch multicenter study was conducted to evaluate the prognostic value of the flare in ALP post-orchidectomy for survival and PFS in 112 patients treated with orchidectomy (previously reported) compared to 121 age- and stage-matched patients additionally treated with estramustine-phosphate (EMP) as first line therapy. RESULTS: There was no overall difference in PFS and survival between the two treatment regimen. Subgroup analysis of patients demonstrating a greater than 50% increase in ALP post-orchidectomy showed, however, a significant increase in PFS in patients additionally treated with EMP. CONCLUSIONS: Our data suggest that the simple measurement of ALP activity within 4 weeks of castration represents a useful adjunct in assessing which patients with prostate cancer undergoing androgen ablation may benefit from additional early chemotherap

The role of selective venous sampling in the management of persistent hyperparathyroidism revisited

Localization studies are mandatory prior to revision surgery in patients with persistent hyperparathyroidism in order to improve surgical outcome and reduce the risk of lengthy explorations. However, in this case, noninvasive localization studies are reported to have a poor sensitivity. The aim of our study is to determine the accuracy of selective venous sampling (SVS) for parathyroid hormone (PTH) in localizing residual hyperactive parathyroid glands in patients with persistent or recurrent hyperparathyroidism. We retrospectively evaluated the localizing accuracy of 20 PTH SVS performed prior to revision surgery in 18 patients with persistent or recurrent primary hyperparathyroidism (n=11) or autonomous (tertiary) hyperparathyroidism (n=7). Tc99m-methoxy-isobutyle-isonitrile (MIBI)-single photon emission computed tomography (SPECT) was also performed in all patients prior to revision surgery. Operative and pathological data were obtained from hospital records. The SVS was able to accurately localize 15 of the 20 pathological glands removed at revision surgery, representing a sensitivity of 75%. This sensitivity is significantly higher than that of Tc99m-MIBI-SPECT, which was only 30% (P=0.012). Our findings demonstrate that SVS is a valuable localization study in patients with persistent or recurrent hyperparathyroidism, with a sensitivity significantly higher than that of Tc99m-MIBI-SPECT. Our data suggest that SVS represents a useful addition to the preoperative workup of these patients prior to revision surger

Determinants of Quality of Life in Adult Patients with Chronic Non-Bacterial Osteomyelitis (CNO) of the Sternocostoclavicular Region (SCCH): A Dutch Single Center Study

Sternocostoclavicular hyperostosis (SCCH), the main clinical manifestation of chronic non-bacterial osteomyelitis (CNO) in adults, is associated with various degrees of chronic pain and restricted shoulder girdle function. We evaluated the impact of CNO/SCCH on quality of life (QoL) and its determinants in 136 adult patients with this rare auto-inflammatory bone disorder using the Short Form 36, Brief Pain Inventory, Brief Illness Perception, Utrecht Coping List, and Shoulder Rating questionnaires. Data were compared with those of the general Dutch population, patients with chronic pain, fibrous dysplasia, or osteoarthritis. Eighty-six (64%) predominantly female (85%) patients with completed questionnaires were included in the study. Sixty-four (75%) had isolated CNO/SCCH. Mean delay in diagnosis was 3.0 &plusmn; 5.5 (SD) years, 90% had variable pain, and 84% limited shoulder function. Compared to healthy and chronically diseased reference populations, CNO/SCCH patients demonstrated significant impairments in almost all aspects of QoL, maladaptive illness perceptions, and ineffective coping strategies. For patients with &gt;5-year delay in diagnosis, higher pain scores and limited shoulder function were identified as determinants for impaired QoL. Patients with CNO/SCCH reported significant impairments in QoL associated with clinical and psychological determinants. Clinical measures such as shortening delay in diagnosis, effective pain management, and psychosocial interventions targeting these factors should help minimize the negative impact of CNO/SCCH on QoL
