Extensive arm skin necrosis following administration of unfractionated heparin

Unfractionated heparin (UH), a commonly used anticoagulant, can rarely cause skin necrosis following heparin-induced thrombocytopenia (HIT). A 38-year-old female, a case of chronic inflammatory demyelinating polyneuropathy (CIDP) admitted to the neurology ward, developed extensive skin necrosis following a change in UH dose at the exact site of UH injection. A sudden fall in the platelet count was observed within 48 h of increasing the UH dose. Necrosis of the outer layer of the skin along with clot formation and inflammation in the inner layers was detected after histopathological evaluation. UH was discontinued, and rivaroxaban was started for the patient as soon as the complication was detected. The patient was discharged in good condition after completing treatment for CIDP without any need for surgical removal of the necrotic tissue. Extensive skin necrosis, as a result of HIT, requires immediate discontinuation of UH and substitution of a nonheparin-based anticoagulation treatment.

Evaluating cognitive impairment in the early stages of Parkinson's disease using the Cambridge brain sciences-cognitive platform

BACKGROUND

Non-motor symptoms (NMS) such as cognitive impairment are among common presentations in patients with Parkinson's disease (PD). In parallel with motor symptoms, these impediments can affect PD patients' quality of life. However, cognitive impairment has received less attention in early PD. On the other hand, the relationship between olfactory symptoms and cognitive impairment is unclear in early PD. Considering the importance of accurate and timely assessment of cognitive function in PD patients using readily available/validated tests, this study has employed the Cambridge Brain Sciences-Cognitive Platform (CBS-CP) as a computer-based tool to assess cognitive presentations in early PD patients.

METHODS

Thirty-four eligible males and females were assigned to PD and healthy controls (HCs). The cognitive performance was assessed using CBS-CP and Mini-Mental State Examination (MMSE), and olfactory function was measured through the standardized olfactory Quick Smell test (QST).

RESULTS

PD patients had poorer performance in all CBS-CP tasks, including short-term memory, attention, and reasoning domains than HCs. Meanwhile, the verbal domain task scores showed no significant difference between groups. PD MMSE results were in the normal range (mean=26.96), although there was a significant difference between the PD and HCs groups (P = 0.000). Our results revealed no correlation between cognitive impairment and olfactory function in PD patients.

CONCLUSION

Given the widely studied features of CBS-CP and its reliability across published evidence, CBS-CP appears to be a suitable measurement to evaluate cognitive impairment in early PD with normal MMSE scores. It seems cognitive and olfactory impairments are independent in early PD.

The hospitalization rate and clinical characteristics of mucormycosis prior and during COVID-19 pandemic: A single-center study

INTRODUCTION

There have been some reports of the association between SARS-CoV-2 infection and mucormycosis. This study aims to compare the hospitalization rates and clinical characteristics of mucormycosis before and during the COVID-19 pandemic.

METHODOLOGY

In this retrospective study, we compared the hospitalization rate of mucormycosis patients in Namazi hospital in Southern Iran for two periods of 40 months. We defined July 1st, 2018 to February 17th, 2020, as the pre-COVID-19 period and February 18th, 2020, to September 30th, 2021, as the COVID-19 period. In addition, a quadrupled group of hospitalized patients with age and sex-matched SARS-COV-2 infection without any sign of mucormycosis was selected as the control group for COVID-associated mucormycosis.

RESULT

In the total of 72 mucormycosis patients in the COVID period, 54 patients had a clinical history and a positive RT-PCR, which confirms the diagnosis of SARS-COV2 infection. The hospitalization rate of mucormycosis showed an increase of + 306% (95% CI: + 259%, + 353%) from a monthly average value of 0.26 (95% confidence interval (CI): 0.14, 0.38) in the pre-COVID period to 1.06 in the COVID period. The use of corticosteroids prior to the initiation of hospitalization (p ≤ 0.01), diabetes (DM) (p = 0.04), brain involvement (p = 0.03), orbit involvement (p = 0.04), and sphenoid sinus invasion (p ≤ 0.01) were more common in patients with mucormycosis during the COVID period.

CONCLUSIONS

In high-risk patients, especially diabetics, special care to avoid the development of mucormycosis must be taken into account in patients with SARS-COV-2 infection considered for treatment with corticosteroids.

Early and mid-term outcomes of carotid angioplasty and stent placement in 579 patients

BACKGROUND AND PURPOSE

Carotid angioplasty and stenting (CAS) could be considered for preventing stroke in patients with carotid artery stenosis. This study aimed to determine the incidence and the risk factors of the early and mid-term complications associated with CAS.

METHODS

This is a retrospective cohort study conducted at Shiraz University of Medical Sciences from March 2011 to March 2019. Patients at high risk and standard risk for carotid endarterectomy were included. The primary composite outcome was defined as stroke, myocardial infarction (MI), and death in the first 30 days after CAS. All-cause mortality, vascular mortality, and stroke were investigated during mid-term follow-up.

RESULTS

A total of 579 patients (618 CAS) were recruited (mean age: 71.52 years). Overall, 394 (68.40%), 211 (36.63%), 179 (31.07%), and 96 (16.72%) patients had hypertension, dyslipidemia, diabetes mellitus, or were cigarette smokers, respectively. Primary composite outcomes were observed in 2.59% of patients (1.55% stroke, 0.69% MI, and 1.72% death). Atrial fibrillation was a predictor of primary composite outcome in multivariate logistic regression (p = .048). The presence of total occlusion in the contralateral carotid artery was significantly associated with the risk of stroke in univariate logistic regression (p = .041). The patients were followed for a period ranging from 1 to 83 months. The overall survival rate for all-cause mortality was 93.48% at 1 year, 77.24% at 5 years, and 52.92% at 8 years. All-cause mortality was significantly higher among patients with symptomatic carotid stenosis (p = .014).

CONCLUSION

CAS provides acceptable short-term and mid-term outcomes in a unique population of high- and standard-surgical-risk, symptomatic and asymptomatic, octogenarian, and nonoctogenarian patients.

Diagnostic accuracy of brain stem auditory evoked response in distinguishing drug-induced parkinsonism from Parkinson'sdisease

OBJECTIVES

Brainstem auditory evoked response (BAER) is a non-invasive modality that can be used to investigate brainstem neuronal function in movement disorders. The differentiation between drug-induced parkinsonism (DIP) and Parkinson's disease (PD) can be very challenging. Although PD and DIP to some extent display similar clinical symptoms, the underlying pathophysiologic mechanisms are entirely different. Given these differences in pathogenesis, and the diagnostic utility of BAER for detecting brainstem function, BAER may help to distinguish between PD and DIP. This study aimed to assess the accuracy and predictive values of BAER parameters in differentiating DIP from PD.

METHODS

We prospectively studied143 participants classified within three groups, including 50 controls, 57 PD, and 36 DIP. BAER was performed on all patients in the study. Patients in the DIP group were followed up for at least one year after discontinuation of the causative drug and examined for final diagnosis. We compared BAER latencies of the three groups and measured sensitivity, specificity, predictive values, likelihood ratios, and accuracy of BAER in diagnosing DIP.

RESULT

Waves V, I-V, and III-V latencies were significantly prolonged among the PD patients compared to the DIP and the control group; however, there were no significant differences in BAER latencies between the DIP and the control group. Waves V and I-V latencies revealed the highest accuracy (86% and 79%, respectively) in distinguishing DIP from PD with high negative predictive value(89% and 83%, respectively) as well as a high negative likelihood ratio (0.2and 0.3, respectively).

CONCLUSION

This study showed that waves V and I-V latencies are significantly prolonged in PD patients compared to those with DIP, consistent with the proposed mechanisms of neurodegeneration in PD, particularly in the midbrain and pons. Consequently, BAER could be used as a useful diagnostic tool for differentiating DIP from PD.

Improving working conditions in an Iranian hospital: a participatory ergonomics approach

Objectives. The future workshop (FW), as a participatory ergonomics approach, is used to change the actual situation of a system into a preferable one. This study was conducted at a major hospital to identify ergonomic problems and provide appropriate solutions for improving working conditions using the FW technique. Methods. Twenty-five mid-level managers of the hospital participated in a 2-day FW. In the critique phase, the ergonomic problems were thoroughly discussed. After brainstorming followed by structuring and grouping of ideas, 75 ergonomic problems were identified and classified into four groups. Solutions and action plans were proposed to improve working conditions. Results. There were nine problems in the personnel-managerial group. Eighteen action plans were proposed to fix them. Stressful occupational factors were the worst problem in this group. Five problems were characterized in the physical space group and 10 action plans were presented. Seven problems were detected in the equipment group, for which 13 action plans were presented. In the welfare group, six problems and 12 action plans were presented. Conclusion. The results revealed that the FW was an appropriate method to find ergonomic bottlenecks in the hospital and a good basis for devising ergonomic interventions.

Studies on the Bottom-Up and Top-Down Neural Information Flow Alterations in Neurodegeneration

BACKGROUND

A proper explanation for perceptual symptoms in neurodegenerative disorders including Alzheimer's disease and Parkinson's disease (PD) is still lacking.

OBJECTIVE

This study aimed at investigating the imbalance between 'bottom-up' and 'top-down' information flow (IF) and processing in PD in relation with visual hallucination symptoms.

METHODS

Here, we looked at bottom-up and top-down IF markers using resting state electroencephalographic (EEG) data from PD patients analyzed through three different IF measures (direct Directed Transfer Function (dDTF), full frequency Directed Transfer Function (ff-DTF), and renormalized Partial Directed Coherence (rPDC).

RESULTS

We observed an increased gamma band IF and a reduced beta band IF in PD patients compared to healthy controls. Additionally, we noticed a reduced theta band IF in PD patients using dDTF as a measure of IF. By source localizing the EEG activity of the PD patients and healthy controls, we looked at the alterations of IF in the prefrontal cortex of PD patients as well.

CONCLUSION

In line with previous studies, our results suggest that the delicate balance between bottom-up and top-down IF is disrupted in Parkinson's disease potentially contributing to the cognitive symptoms of PD patients.

Efficacy of oral administration of licorice as an adjunct therapy on improving the symptoms of patients with Parkinson's disease, A randomized double blinded clinical trial

ETHNOPHARMACOLOGICAL RELEVANCE

Licorice preparations are used as neuroprotective remedies in Persian ethnomedicine, in order to prevent from disabilities in neurodegenerative conditions like Parkinson's disease (PD).

AIM OF THE STUDY

This study was designed to determine the licorice (root of Glycyrrhiza glabra L.) effectiveness as an adjunct treatment in the PD management.

MATERIAL AND METHODS

In this double-blinded trial, 128 patients were assessed for eligibility criteria. Seventy-eight patients were ineligible and 11 of them refused from participating. Thirty-nine PD patients (YAHR staging ≤ 3) were divided into two groups by random. The patients received oral licorice or placebo syrups with a dose of 5 cc, twice a day for 6 months. High-performance liquid chromatography and spectrophotometric instruments determined licorice syrup constituents. The patients' situation for Unified Parkinson's rating scale (UPDRS) was assessed every 6 weeks for the duration of six months. In addition, patients' blood pressure, blood glucose, sodium and potassium levels, quality of life and dizziness were determined.

RESULTS

Six weeks after intervention, total UPDRS, daily activities and tremor were significantly improved with a considerable effect size. A significant better motor test and rigidity scores were observed 4 months after licorice intake (p > 0.05). No electrolyte abnormality, significant changes in blood pressure or blood glucose levels were observed during the study. Each 5cc of syrup contained 136 mg of licorice extract with 12.14 mg glycyrrhizic acid, and also 136 μg of polyphenols.

CONCLUSION

The licorice intake could improve the symptoms in PD patients without serious adverse events.

CRISPR System: A High-throughput Toolbox for Research and Treatment of Parkinson's Disease

In recent years, the innovation of gene-editing tools such as the CRISPR/Cas9 system improves the translational gap of treatments mediated by gene therapy. The privileges of CRISPR/Cas9 such as working in living cells and organs candidate this technology for using in research and treatment of the central nervous system (CNS) disorders. Parkinson's disease (PD) is a common, debilitating, neurodegenerative disorder which occurs due to loss of dopaminergic neurons and is associated with progressive motor dysfunction. Knowledge about the pathophysiological basis of PD has altered the classification system of PD, which manifests in familial and sporadic forms. The first genetic linkage studies in PD demonstrated the involvement of Synuclein alpha (SNCA) mutations and SNCA genomic duplications in the pathogenesis of PD familial forms. Subsequent studies have also insinuated mutations in leucine repeat kinase-2 (LRRK2), Parkin, PTEN-induced putative kinase 1 (PINK1), as well as DJ-1 causing familial forms of PD. This review will attempt to discuss the structure, function, and development in genome editing mediated by CRISP/Cas9 system. Further, it describes the genes involved in the pathogenesis of PD and the pertinent alterations to them. We will pursue this line by delineating the PD linkage studies in which CRISPR system was employed. Finally, we will discuss the pros and cons of CRISPR employment vis-à-vis the process of genome editing in PD patients' iPSCs.

Initial Results of Bilateral Subthalamic Nucleus Stimulation for Parkinson Disease in a Newly Established Center in a Developing Country: Shiraz, Southern Iran

OBJECTIVE

To report the establishment of a new center for deep brain stimulation (DBS) as a surgical treatment for Parkinson disease and the surgical outcomes, from 2014 to 2017 in Shiraz, Southern Iran.

METHODS

A new treatment program was established in Shiraz through a multidisciplinary team in 2014. Thirty-four patients underwent implantation of subthalamic nucleus (STN) electrodes during the last 3 years. Twenty-five patients fulfilled the minimum 6-month follow-up criteria. The baseline Unified Parkinson Disease Rating Scale (UPDRS) was assessed 1 month before surgery in both off-medication and on-medication states by a movement disorder neurologist. To evaluate the outcomes, subscores of the UPDRS were assessed in all patients before surgery and at least 6 months after the operation.

RESULTS

All 25 patients had advanced Parkinson disease categorized as stage 3 or 4 using the Hoehn and Yahr scale. STN DBS resulted in a dramatic improvement in motor function of most patients. A reduction in dopaminergic medication dosage (average 60% reduction) was observed. The mean improvement was 40% in UPDRS II and 67% in UPDRS III. No surgical or hardware complications were observed. Stimulation-related adverse effects, including increased falling and worsening of speech, occurred in a few patients after surgery. Most of the patients experienced weight gain after surgery.

CONCLUSIONS

Bilateral STN DBS is a satisfactory and safe treatment for carefully selected patients with advanced Parkinson disease. According to the results, the procedure can be performed safely and with comparable results in developing countries around the world.

Investigation of ischemic and demyelinating lesions by cerebral vasoreactivity based on transcranial Doppler sonography: a comparative study

PURPOSE

Variations of cerebral blood flow in response to hypoxia and hyperoxia in different disease conditions can provide new insights into disease etiopathogenesis. This study aimed to determine the characteristics of cerebral vasoreactivity for ischemia and demyelination.

MATERIALS AND METHODS

This case-control study included: 28 patients with lacunar infarctions verified by history, physical examination, and MRI; 28 age- and sex-matched healthy controls; 28 patients with relapsing-remitting multiple sclerosis (MS), based on McDonald criteria; and 28 age- and sex-matched healthy controls for the MS group. Transcranial Doppler sonography was undertaken in all subjects to calculate the mean flow velocity (MFV) of the right middle cerebral artery (MCA) and, after a breath-holding (BH) maneuver, the breath-holding index (BHI) was determined.

RESULTS

There was no significant difference of BHI and changes of MFV of the MCA in MS patients compared to controls (1.02 ± 0.4 vs 1.02 ± 0.3, p = 0.993; and 16.8 ± 8.1 vs 11.3 ± 10.8, p = 0.057). BHI in patients with lacunar infarctions was significantly lower (0.8 ± 0.4 vs 1.2 ± 0.3, p < 0.001) compared to controls. The BHI (p = 0.040) and variations of MFV of MCA (p = 0.007) in MS patients were significantly higher than in patients with lacunar infarctions. The vasoreactivity of demyelinating lesions was higher than that of ischemic ones.

CONCLUSION

Therefore, cerebral vasoreactivity determined by transcranial Doppler could be utilized for differentiating demyelinating from ischemic lesions.

Detecting and managing drug-related problems in the neurology ward of a tertiary care teaching hospital in Iran: A clinical pharmacist's intervention

Objective:

Nowadays, the role of clinical pharmacists has become more prominent by more clinical pharmacists joining the health-care teams. This study was aimed to assess the role of a clinical pharmacist specialist in detecting and managing drug-related problems (DRPs) in the neurology ward of a tertiary care teaching hospital in Iran.

Methods:

This is a prospective cross-sectional study conducted on 123 hospitalized patients admitted to the neurology ward of a teaching hospital. The clinical pharmacist visited the patients and filled out the designed pharmacotherapy sheet for each patient. Then, the general pharmacist checked the patients' files and pharmacotherapy sheets and categorized DRPs using modified method of “The Pharmaceutical Care Network Europe classification, Version 5.01.”

Findings:

A total of 168 errors were found and 346 interventions were done by the clinical pharmacist during the study period. The most common form of errors in our study was “drug choice problems” (57.76%). The acceptance rate of interventions was 41.91% among physicians.

Conclusion:

The large number of interventions reported in several studies, as well as this study, revealed that clinical pharmacy services could contribute to a rationalization of drug therapy and may eventually lead to more medication safety.

Treatment of Idiopathic Intracranial Hypotension With Tea: A Case Report

INTRODUCTION

The syndrome of spontaneous intracranial hypotension has been increasingly diagnosed since its discovery through magnetic resonance imaging (MRI). It is a rare syndrome that is due to the leakage of cerebrospinal fluid (CSF) from a tear in the dura and can occur at any age, even among adolescents, but is most frequently seen among females in late middle age.

CASE PRESENTATION

Here, we describe a 32-year-old woman with a two-month history of headaches and occasional nausea and vomiting (N/V). MRI without gadolinium was normal, but meningeal enhancement was seen in MRI with gadolinium. The lumbar puncture revealed a low opening pressure. Computed tomography myelography (CT myelography) showed no leakage; Therefore, idiopathic intracranial hypotension was diagnosed. Treatment was started using tea, and the patient's headache got significantly better in about a day.

CONCLUSIONS

Conservative therapy, such as bed rest and caffeine treatment with eight cups of tea daily, yielded a significant improvement in our patient. Effectively, the patient constitutes a case of idiopathic intracranial hypotension due to undetectable CSF leakage or hyper-absorption, with good response to conservative management through tea-drinking. Further investigations with an appropriate sample size are needed in order to confirm this intervention in the treatment of idiopathic intracranial hypotension.

Migraine responds better to a combination of medical therapy and trigger point management than routine medical therapy alone

BACKGROUND

Migraine is one of the most frequent headaches. Cervical myofascial and trigger point disorders are effective factors on accession of this type of headache. PRT is an indirect technique that treats trigger points.

OBJECTIVE

The purpose of this study was to compare the effectiveness of trigger points' management by positional release therapy (PRT) combined with routine medical therapy and routine medical therapy alone in treatment of migraine headache.

METHODS

Forty-four patients with active trigger points in cervical muscles entered to the study. They were randomly assigned to PRT-medical therapy or medical therapy group. Headache frequency, intensity, duration and tablet count were recorded by use of a daily headache diary. The sensitivity of trigger points was assessed by the use of a digital force gauge (Wagner-FDIX). Cervical range of motion was measured by a goniometer.

RESULTS

Both groups showed significant reduction in headache intensity, frequency, duration and tablet count after 4 months follow up. The sensitivity of trigger points and all cervical range of motions significantly increased in PRT-medical group after 4 months follow up; however in medication group except cervical right lateral flexion, right and left rotation the other factors showed no change after 4 months follow up. In comparison of the two study groups, there was no significant difference in headache-related variables. Apart from the headache intensity and tablet count, the trends of other factors were significantly different between the two groups (p <  0.05).

CONCLUSIONS

The combined PRT-medical therapy is more effective than the medical therapy alone. Thus, the combination of PRT and medical therapy is suggested as a treatment choice for patients with migraine headache.

Pseudo-Foster Kennedy Syndrome as a Rare Presentation of Vitamin B12 Deficiency

Introduction

Pseudo-Foster Kennedy syndrome is a triad consisting of ipsilateral optic atrophy, contralateral optic disc edema, and ipsilateral anosmia in the absence of an intracranial mass. Vitamin B12 plays an important role in DNA synthesis, and its deficiency causes peripheral neuropathy, myeloneuropathy, and, very rarely, optic neuropathy.

Case Presentation

In this study, we describe a 34-year-old male who presented with progressive loss of visual acuity and field. Fundoscopy showed optic disc edema with telangiectasia in the right eye, while the left eye had optic disc atrophy. We ruled out nearly all possible and common causes of optic neuropathy, and vitamin B12 deficiency was finally diagnosed. After treatment with vitamin B12, the patient improved.

Conclusions

Demyelinating disease, anterior ischemic optic neuropathy, non-arteritic anterior ischemic optic neuropathy, autoimmune disease, and hereditary optic neuropathy could cause optic neuropathy. Normal CBC parameters and the absence of clinical manifestations of vitamin B12 deficiency could not rule out its diagnosis. Careful physical examinations and history-taking with a classical approach led us to the diagnosis of vitamin B12 deficiency and its treatment.

Immune Rebound: Multiple Sclerosis after Treatment of Cushing's Disease

High cortisol level in endogenous Cushing's syndrome suppresses the immune system and after treatment there may be an over activity of immune reaction leading to autoimmune diseases mostly thyroid and rheumatologic disorders. This is the second reported case of multiple sclerosis developing after treatment of Cushing's syndrome. A 42-year old man is reported who presented with bone fracture and osteoporosis and diagnosed with Cushing's disease. Six months after surgical treatment of his pituitary adenoma, he developed progressive multiple sclerosis. We conclude that after treatment of endogenous Cushing's syndrome, the patients should be watched for development of autoimmune disorders including those affecting the central nervous system.

Development and Assessment of a Gas Chromatographic Based Method for the Quantification of Thymol from Cream Based Formulation

INTRODUCTION

Herbal medicines have been used for different illnesses. However, standardization of these medicaments should be done before introducing for treatment purposes. Ajwain an essential oil, is traditionally used for neuropathic pain.

OBJECTIVE

To develop and assess a gas chromatographic-based method for the quantification of thymol in Ajwain essential oil, current work was performed.

METHODOLOGY

Both pure thymol and Ajwain creams were prepared and subjected to hydrodistillation method under temperature-controlled procedure to re-extract the applied essential oil and pure thymol. Previously, Ajwain seeds essential oil composition was analyzed and identified using GC/MS. After re-extraction, GC/FID was applied quantitatively to determine the thymol content in the Ajwain and thymol creams. The parameters represented in International Conference on Harmonization (ICH) guidelines were considered for the determination.

RESULTS

Thymol content in a 50 g laminated tube of Ajwain cream was calculated as 2.34 g ± 0.02. Regarding the total thymol content of a 50 g laminated tube of Thymol cream (2.43 g), recovery percent for Ajwain cream was calculated as 96.29 %.

CONCLUSION

Using hydrodistillation for an essential oil- containing cream sample via Clevenger proved to be a simple and convenient method to work up and extract active volatile components of such semisolid formulation. However, the extraction yield was profoundly related to the condenser temperature. The current employed determination method is introduced as a rapid and reliable method and thus, can be suggested for the quality control assessment of phytopharmaceutical semisolid preparations containing thymol and similar volatile constituents.

The Prevalence and Factors Contributing to Hemodynamic Depression in Patients Undergoing Carotid Angioplasty and Stenting

BACKGROUND

Hemodynamic depression, including bradycardia and hypotension, is among the most common complications of carotid angioplasty and stenting.

METHODS AND MATERIAL

A prospective, cross-sectional study was conducted at Shiraz University of Medical Sciences in southern Iran from 2011 to 2013. Consecutive patients undergoing carotid angioplasty and stenting were included. Demographic data, atherosclerotic risk factors, preprocedural blood pressure, the site of stenosis, the degree of stenosis, and data regarding technical factors were recorded. Hemodynamic depression was defined as a systolic blood pressure less than 90 mmHg and/or heart rate less than 50 beat/min.

RESULTS

About 170 patients (67% male, mean age: 71+9.8, 55.9% right side, 82.9% symptomatic) were recruited. Mean degree of stenosis was 79.4% in operated side and 40.7% in nonoperated side. Predilation, postdilation, or both were conducted in 18(10.5%), 141(83%), 11(6.5%) patients respectively. Thirteen (7.6%), 41(24%), and 12(7%) of patients developed postprocedural bradycardia, hypotension or both, respectively. Two patients had a stroke after CAS and periprocedural mortality was 0%. Hemodynamic depression after CAS had a significant association with preprocedure blood pressure and the use of an open cell stent design, but not with atherosclerotic risk factors, site and/or degree of stenosis, predilation, or postdilation. Hemodynamic depression significantly increased hospital stay too.

CONCLUSION

Preprocedural hydration and close-cell stents may decrease the risk of poststenting hemodynamic depression.

Implementation of Pharmaceutical Practice Guidelines by a Project Model Based: Clinical and Economic Impact

All around the world a few studies have been found on the effect of guideline implementation on direct medications' expenditure. The goal of this study was to evaluate cost savings of guideline implementation among patients who had to receive 3 costly medications including albumin, enoxaparin, and pantoprazole in a tertiary hospital in Shiraz, Iran.An 8-month prospective study was performed in 2 groups; group 1 as an observational group (control group) in 4 months from June to September 2014 and group 2 as an interventional group from October 2014 to January 2015.For group 1 the pattern of costly medications usage was determined without any intervention. For group 2, after guideline implementation, the economic impact was evaluated by making comparisons between the data achieved from the 2 groups.A total of 12,680 patients were evaluated during this study (6470 in group 1; 6210 in group 2). The reduction in the total value of costly administered drugs was 56% after guideline implementation. Such reduction in inappropriate prescribing accounts for the saving of 85,625 United States dollars (USD) monthly and estimated 1,027,500 USD annually.Guideline implementation could improve the adherence of evidence-based drug utilization and resulted in significant cost savings in a major teaching medical center via a decrease in inappropriate prescribing of costly medications.

Demographic and Technical Risk Factors of 30-Day Stroke, Myocardial Infarction, and/or Death in Standard- and High-Risk Patients Who Underwent Carotid Angioplasty and Stenting

BACKGROUND

Carotid angioplasty and stenting (CAS) is an accepted treatment to prevent stroke in patients with carotid artery stenosis. The purpose of this study is to identify risk factors for major complications after CAS.

MATERIALS AND METHODS

This is a prospective study that was conducted at Shiraz University of Medical Sciences in southern Iran from March 2011 to June 2014. Consecutive patients undergoing CAS were enrolled. Both standard- and high-risk patients for endarterectomy were enrolled. Demographic data, atherosclerotic risk factors, site of stenosis, degree of stenosis, and data regarding technical factors were recorded. Thirty-day stroke, myocardial infarction, and/or death were considered as the composite primary outcomes of the study.

RESULTS

A total of 251 patients were recruited (mean age: 71.1 ± 9.6 years; male: 65.3%). Of these, 178 (70.9%) were symptomatic, 73 (29.1%) were diabetic, 129 (51.4%) were hyperlipidemic, 165 (65.7%) were hypertensive, and 62 (24.7%) patients were smokers. CAS was performed for left internal carotid artery (ICA) in 113 (45.4%) patients. Fourteen (5.6%) patients had sequential bilateral stenting. Mean stenosis of operated ICA was 80.2 ± 13.8%. An embolic protection device was used in 203 (96.2%) patients. Pre- and postdilation were performed in 39 (18.5%) and 182 (86.3%) patients, respectively. Composite outcomes were observed in 3.6% of patients (3.2% stroke, 0% myocardial infarction, and 1.2% death). Left-sided lesions and the presence of diabetes mellitus were significantly associated with poor short-term outcome (p = 0.025 and p = 0.020, respectively).

CONCLUSION

There was a higher risk of short-term major complications in diabetic patients and for left carotid artery intervention.

Effect of Motor Imagery on the F-Wave Parameters in Hemiparetic Stroke Survivors

Objective

To assess the effect of motor imagery, as a rehabilitation method in stroke, on F-wave parameters that undergo changes during upper motor neuron involvement.

Methods

Twenty-one fully conscious hemiparetic stroke survivors with a completely plegic hand (power 0/5) and a minimum interval of 72 hours since stroke were recruited into this study. The mean F-wave latency, amplitude, and persistence in the median and ulnar nerves were measured in both the affected and non-affected sides at rest and in the paretic hand during a mental task. Comparison was made between data from the affected hand and the non-affected hand as well as between data from the affected hand at baseline and during motor imagery.

Results

Patients had significantly different F-wave persistence between the affected and non-affected sides (paired t-test, p<0.001). Motor imagery could improve F-wave persistence in both the investigated nerves (paired t-test, p=0.01 for ulnar nerve and p<0.001 for median nerve) and F-response amplitude in the median nerve (paired t-test, p=0.01) of the affected limb.

Conclusion

The amplitude and persistence of F-wave were improved during motor imagery, representing F-wave facilitation. This result suggests that motor imagery can restore motor neuron excitability, which is depressed after stroke.

Large-vessel stenosis in the patients with ischemic stroke in Iran: Prevalence, pattern, and risk factors

BACKGROUND

Large artery disease (LAD) is a common cause of stroke, but a little is known regarding its role in Iranian stroke patients. The current study investigates the prevalence and risk factors for cervicocephalic arterial stenosis in the patients with ischemic stroke using digital subtraction angiography (DSA).

METHODS

This was a prospective cross-sectional study performed in hospitals affiliated to Shiraz University of Medical Sciences from March 2011 to March 2013. Patients with ischemic stroke underwent noninvasive vascular and cardiac investigations to find the etiology of the stroke. Patients suspected of having large artery stenosis underwent DSA. The severity of the stenosis was calculated according to the North American Symptomatic Carotid Endarterectomy (NASCET) and Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) Trial criteria. The presence of cigarette smoking, hyperlipidemia, hypertension, and diabetes mellitus were documented for all subjects.

RESULTS

A total of 3703 stroke patients were identified. Of them, 342 patients (62.3%, male) underwent DSA for LAD. The mean age at the time of angiography was 66.7±10.3 years. Extracranial and intracranial arteries were involved in 305 (89.2%) and 162 (47.4%), respectively. And 301 patients (88%) had anterior circulation and 128 patients (37.4%) had posterior circulation involvement. Diabetes mellitus but not age, sex, hypertension, hyperlipidemia, or smoking was significantly associated with intracranial involvement. (P = 0.002).

CONCLUSION

It can be concluded that the distribution of the large arterial atherosclerotic disease in Iran is similar to that seen in North America and Europe. Intracranial stenosis was more prevalent in diabetic patients.

Management of insomnia in traditional Persian medicine

Insomnia is a sleep disorder which affects 10-48% of general population. Different measures, such as pharmacotherapy and behavioral management, are applied for insomnia and associated complaints. In traditional medical systems, herbal medicines are considered beneficial. Therefore, the present paper compiles pharmacological and medical insights into the management of insomnia according to Traditional Persian Medicine. Herein, preserved medical and pharmaceutical manuscripts of Persian medicine from 10th to 18th century A.D. were investigated for information about concepts of insomnia treatment and herbal remedies. Additionally, for all herbal remedies, an extensive search of scientific databases, such as MEDLINE and Scopus, has been performed to find related works concerning hypnotic, sedative, and anxiolytic as well as narcoleptic effects. Insomnia (generally called Sahar in Persian manuscripts) is a well-known disorder. Herbal medical intervention was the major treatment prescribed by Iranian physicians. Totally, 36 medicinal herbs related to 25 plant families are derived from the searched literature. These remedies were applied orally, topically, and nasally. Based on scientific data, 50% of reported herbs have relevant pharmacological effects. Besides historical elucidation, this paper presents medical and pharmacological approaches that had been applied by Persian practitioners in order to deal with sleep complications. Considering the fruitful results of these findings, this essay should encourage researchers to conduct more investigations in this field in order to understand the mechanisms and effects of traditionally applied herbs still unknown to modern medicine.

Outcome of decompressive craniectomy in comparison to nonsurgical treatment in patients with malignant MCA infarction

Background

Malignant cerebral infarction is a well-recognized disease, comprising 10-15% of all cases with cerebral infarction and causing herniation and death in 80% of cases. In this study, we compare the effects of decompressive craniectomy versus conventional medical treatment on mortality rate and functional and neurological outcome in patients with malignant MCA infarction.

Methods

We performed a prospective case–control study on 60 patients younger than 80years of age suffering malignant MCA cerebral infarction. The case group underwent decompressive craniectomy in addition to routine aggressive medical care; while the control group received routine medical treatment. Patient outcome was assessed using Glasgow outcome scale and modified Rankin scale within three months of follow-up. The data were analyzed by SPSS version 16.0 software using Chi Square, One-way ANOVA and Mann–Whitney tests.

Results

There were 27 male and 33 female patients with a mean age of 60.6 years (SD = 12.3). Glasgow outcome scale score averaged 2.93 in the surgical versus 1.53 in the medical group; this difference was significant (p = 0.001). Outcome in modified Rankin scale was also significantly lower in the surgical (3.27) versus medical (5.27) group (p < 0.001). Surgery could decrease the mortality rate about 47%.

Conclusion

In this study, decompressive craniectomy could decrease mortality rate, and improve neurological and functional outcome, and decrease long-term disability in patients with malignant MCA infarction.

Analysis of the essential oil components from different Carum copticum L. samples from Iran

Background:

The family Apiaceae is defined with the diversity of essential oil. Fruits of Ajwain (Carum copticum), a famous herb of Apiaceae, accumulate up to 5% essential oil which is remarked as important natural product for food and flavoring industry, as well as pharmacological approaches. It is believed that differences in essential oil profile in a certain plant are resulted from various cultivation situations and locations, time of cultivation and also different extracting method.

Objective:

Present study aimed to evaluate major components of ten different collected Ajwain samples from random cultivation locations of Iran.

Materials and Methods:

Samples were individually subjected to hydrodistillation using a Clevenger-type apparatus for the extraction of essential oil. GC/MS analysis for samples was carried out using Agilent technologies model 7890A gas chromatograph with a mass detector.

Results:

The yield of extracted essential oil was calculated as 2.2 to 4.8% (v/w) for ten samples. Major oil components were thymol, para-cymene and gamma-terpinene. Five of ten samples have thymol as the main component with amount of 35.04 to 63.31%. On the other hand, for four samples, para-cymene was major with amount of 40.20 to 57.31% and one sample had gamma-terpinene as main constituent containing 37.43% of total oil. Accordingly, three different chemotypes, thymol, para-cymene and gamma-terpinene can be speculated from collected samples.

Conclusion:

While these components possess pharmacological effect, screening of different chemotypes not only represent the effect of cultivation situations and locations but also can be beneficial in further investigation.

Living with and caring for patients with Alzheimer's disease in nursing homes

INTRODUCTION

Many of the patients with Alzheimer disease are taken care of in nursing homes. However the literature on the experiences of Iranian formal caregivers of older adults with Alzheimer disease is scarce. This qualitative study explored the caring experiences of formal caregivers in nursing homes that can improve the quality of care and patient's quality of life.

METHODS

This qualitative study used the principles of descriptive content analysis to analyze these data. Our participants included 11 female and 3 male caregivers aged 25 to 38 years who were selected for interviewing based on a purposive sampling method. The data were analyzed with a content analysis method.

RESULTS

Nearly 900 initial codes were extracted and categorized into 6 main themes including "managing difficult behaviors", "dependence on familial care", "continuum of different feelings", "care for a child", "living with the patients" and "not understanding the patients", which was further analyzed in the two subcategories "caring without enough information" and " a dead man moving". conclusion: The care provided by our informants was mainly influenced by attitudes, culture and religious beliefs of caregivers about family attachment and ample driven reward of helping and caring frail or old people in Islam. These cultural and religious beliefs could facilitate provision of care and confrontation with patients' child-like behaviors. It is suggested that employment of trained staff and plans for their continued education can improve the quality of care and the quality of the patient's life.

Cerebral Artery Velocity Determined by Transcranial Doppler Ultrasonography in Patients With β-Thalassemia Intermedia Compared to β-Thalassemia Major

We aimed to compare cerebral artery velocity and relevant clinical factors in patients with β-thalassemia intermedia (β-TI), β-thalassemia major (β-TM), and healthy individuals. For this study, 60 patients with β-TM and 64 with β-TI were randomly selected. Sixty healthy adults comprised the control group. Time average maximum mean velocity (TAMMV) was measured in large cerebral arteries with transcranial Doppler (TCD) ultrasonography. In all arteries, TAMMV was significantly higher in the β-TI group than that of β-TM or controls ( P < .001). Patients with β-TM had significantly higher TAMMV than controls in most arteries evaluated ( P < .001). Overall, the lack of regular blood transfusions, splenectomy, and lower age (to a lesser extent) was found to be independent influencing factors contributing to high cerebral artery velocities. Further detailed longitudinal studies are needed to confirm these results and to determine the risk of silent infarction and stroke in patients with thalassemia and abnormal TCD, with particular focus on patients with β-TI.

Types of headache and those remedies in traditional persian medicine

The history of headache, as a common neurological complication, goes back to almost 9000 years ago. Many ancient civilizations present references to headaches and the coherent treatment strategies. Accordingly, several documents comprising headache complications embodying precise medical information stem from Traditional Persian Medicine (TPM) that can provide useful opportunities for more comprehensive treatment. We conducted a survey on headache through original important pharmacopeias and other important medical manuscripts of TPM which were written during 9(th) to 19(th) centuries and have derived all headache categories and herbal remedies. An extensive search of scientific data banks, such as Medline and Scopus, has also been exercised to find results relating to the anti-inflammatory, anti-nociceptive, and analgesic effects of denoted medicinal herbs. The concept of headache and treatments in TPM covers over 20 various types of headache and more than 160 different medicinal plants administered for oral, topical, and nasal application according to 1000 years of the subject documents. Nearly, 60% of remarked medicinal herbs have related anti-inflammatory or analgesic effects and some current headache types have similarities and conformities to those of traditional types. Beside historical approaches, there are many possible and available strategies that can lead to development of new and effective headache treatment from medicinal plants so that this study can provide beneficial information on clinical remedies based on centuries of experience in the field of headache which can stand as a new candidate for further investigations.

Characteristics of care and caregivers of Alzheimer's patients in elderly care homes: a qualitative research

BACKGROUND

Due to the increase in the number of Alzheimer's patients in Iran and also the limitation of cultural knowledge about caring of these patients, this study was designed to explore the perceptions of Iranian caregivers about caring Alzheimer patients in the elderly care homes.

METHODS

A qualitative content analysis method was conducted on two elderly care homes of Shiraz/Iran, during 2009-2011. Fourteen key informants (10 women and 4 men, between 25-35 years of age), who had been working in elderly care homes caring for the elderly with Alzheimer disease for about 1-11 years (Mean=30 months) were selected by purposive sampling method. The caring experience and ability of transferring their experience to others were the main criteria for selection of the participants. They were participated in 2 focus groups and 4 interviews.

RESULTS

Nearly, 800 initial codes were extracted and categorized into 3 groups of "multidimensional care", "going along with the patients" and "need to be professional" and 12 subcategories. Although several aspects of care were mentioned by the participants but the main aspect was physical care. Infantilizing the patients was the main feature of care and caring personality was an important characteristic of caregivers.

CONCLUSION

An appropriate schedule of care considering main categories and subcategories of this research based on cultural context should be prepared. Moreover, consistent promotion of the schedule, employment of trained staff and plans for continued education for them can improve the quality of care and patient's life in elderly care homes.

Helicobacter pylori infection in patients with epilepsy

BACKGROUND

The possible role of Helicobacter pylori (HP) infection in extra-intestinal diseases has been suggested. The main purpose of this study was to determine the frequency of infection with HP in two groups of patients with epilepsy: patients with idiopathic generalized epilepsy (IGE) and patients with temporal lobe epilepsy (TLE), compared to healthy controls.

METHODS

In this cross-sectional study a random sample of adult patients above 18 years of age with a diagnosis of IGE or TLE were recruited at the outpatient epilepsy clinic at Shiraz University of Medical Sciences, from January 2009 through June 2011. A group of healthy individuals were included as control group. For all patients and controls a urea breath test (UBT) was requested.

RESULTS

Thirty-four patients with IGE, 28 patients with TLE and 33 individuals as control were recruited. Positive UBT was observed in 21 individuals (61.8%) with IGE, 50% (14 patients) of patients with TLE and 72.7% (24 individuals) in control group. The difference between patients with IGE and control group was not significant (P=0.3). The difference between patients with TLE and control group was not significant either (P=0.068).

CONCLUSION

The rate of HP infection was not higher in patients with epilepsy compared to healthy individuals. At the moment, there is not enough epidemiological data to support the role of HP infection in patients with either IGE or TLE.

Meningoencephalitis with Aspergillus and mycobacterium tuberculosis in a renal transplant recipient

OBJECTIVES

We report a case of central nervous system coinfection with 2 types of opportunistic organisms-Aspergillus and Mycobacterium tuberculosis-in a 33-year-old woman who underwent a renal transplant.

MATERIALS AND METHODS

She developed a high-grade fever and right-sided weakness 1 month after the transplant while on mycophenolate mofetil, prednisolone, and cyclosporine.

RESULTS

Brain magnetic resonance imaging revealed multiple mass lesions with peripheral ring enhancement. Colony-stimulating factor polymerase chain reaction was positive for Aspergillus and Mycobacterium tuberculosis.

CONCLUSIONS

Broad-spectrum antibiotics, antituberculous agents, and amphotericin were started. Unfortunately, the woman's condition deteriorated, and she died 2 weeks after admission to the hospital.

Patent foramen ovale in patients with tension headache: is it as common as in migraineurs? An age- and sex-matched comparative study

The association of patent foramen ovale (PFO) and atrial septal aneurysm (ASA) with migraine headache attack (MHA) has been clearly shown. The same findings have been recently demonstrated also in cluster headache. Although tension-type headaches (TTH) are the most common kind of headache, their association with these atrial septal abnormalities has never been studied before. The study was conducted to clarify whether there was a significant association between the presence of such atrial septal abnormalities and tension headache, when compared with migraineurs. One hundred consecutive patients with migraine and 100 age- and sex-matched subjects with TTH and 50 healthy volunteers with no headache were enrolled in the study and underwent a complete transesophageal echocardiographic study with contrast injections at rest and with the Valsalva maneuver. There was no significant difference between the age and the sex of the participants of the three groups. The overall prevalence of PFO was 23% in patients with TTH and that of large PFOs was only 11%. The 23% prevalence of PFO in patients with TTH was not statistically different from 16% found in our normal control group. Furthermore, we found a significantly higher prevalence of PFO in migraineurs (50%) when compared with patients with tension headache (p < 0.001). This was also true for the collective presence of large PFOs and ASAs (35%) (p < 0.001). Although atrial septal anomalies have an association with MHA, they do not have a significant association with TTH.

Serum creatine phosphokinase is helpful in distinguishing generalized tonic-clonic seizures from psychogenic nonepileptic seizures and vasovagal syncope

OBJECTIVE

Distinguishing epileptic generalized tonic-clonic seizures (GTCS) from either psychogenic nonepileptic seizures (PNES) or vasovagal syncope (VVS) is important. In this study, we investigated the use of postictal serum creatine phosphokinase (CPK) concentrations in distinguishing between these events.

METHODS

Patients admitted to the Neurology Ward at Namazi Hospital in Shiraz, Iran, with an attack of transient loss of consciousness and abnormal movements witnessed by a neurologist were studied. We categorized the patients into three groups: 20 patients with GTCS, 22 with VVS, and 20 with PNES. A group of 20 normal healthy individuals were included in the study as the control group. Serum CPK concentration was measured 12-15 h after the attack in all patients and at one time in the control group. A P value less than 5% was considered significant.

RESULTS

There were no significant differences between the four groups with respect to age and sex. Mean CPK concentrations statistically significantly differed between the four groups, with higher levels in patients with GTCS (P=0.0001). Serum CPK concentration had a sensitivity of 75% and specificity of 86% for the diagnosis of GTCS. CPK concentration was above 160 mg/dl in 75% of patients with GTCS, 15% of patients with PNES, 13.6% of patients with VVS, and 15% of the control group (P=0.0001). The PNES, VVS, and control groups did not statistically significantly differ with respect to CPK concentrations.

CONCLUSION

In patients with a recent loss of consciousness and abnormal movements, serum CPK concentration is a useful, practical, and relatively accurate parameter to assist in the differentiation of epileptic seizures from either VVS or PNES.
