Spirituality in Parkinson's Disease within a Sample from the USA.

Spirituality and religious beliefs are important for coping with medical conditions. The dopaminergic system is involved in reward behavior, and its dysfunction in Parkinson Disease (PD) raises questions about religiosity and spirituality in people with PD. This study examines the association between levels of spirituality and religiosity and the severity of PD motor and non-motor symptoms. The secondary aim investigates the perceived impact of PD diagnosis on spirituality and religiosity. This was a cross-sectional analysis of demographic, physical, mental, and spirituality and religiosity status in patients with PD recruited for the Health Outcomes Measurement (HOME) Study at the University of Maryland Parkinson Disease and Movement Disorders Center, Baltimore, USA. Spirituality and religiosity were assessed using the Spiritual Well-being Scale, and the World Health Organization Quality of Life Spiritual Religious and Personal Belief field-test instrument. The sample size was 85 PD patients. The mean age (standard deviation) was 65.5 (9.4) years and 67.1% were male. Higher levels of spirituality and religiosity were associated with younger age, sex (female), less education, religious affiliation (Christian), and mental health status. After adjusting for age, education, gender, race, marital status, religion, physical health, mental health, and comorbidity, only anxiety was associated with all of the spirituality/religiosity assessments. The majority of patients reported no change in their religious or spiritual beliefs following diagnosis. Greater spirituality and religiosity were associated with less anxiety. Also, younger women with PD showed higher levels of spirituality and religiosity. Longitudinal studies on more diverse populations are needed.

Accumulation of pTau231 at the Postsynaptic Density in Early Alzheimer's Disease.

BACKGROUND: Phosphorylated cytoplasmic tau inclusions correlate with and precede cognitive deficits in Alzheimer's disease (AD). However, pathological tau accumulation and relationships to synaptic changes remain unclear. OBJECTIVE: To address this, we examined postmortem brain from 50 individuals with the full spectrum of AD (clinically and neuropathologically). Total tau, pTau231, and AMPA GluR1 were compared across two brain regions (entorhinal and middle frontal cortices), as well as clinically stratified groups (control, amnestic mild cognitive impairment, AD dementia), NIA-AA Alzheimer's Disease Neuropathologic Change designations (Not, Low, Intermediate, High), and Braak tangle stages (1-6). Significant co-existing pathology was excluded to isolate changes attributed to pathologic AD. METHODS: Synaptosomal fractionation and staining were performed to measure changes in total Tau, pTau231, and AMPA GluR1. Total Tau and pTau231 were quantified in synaptosomal fractions using Quanterix Simoa HD-X. RESULTS: Increasing pTau231 in frontal postsynaptic fractions correlated positively with increasing clinical and neuropathological AD severity. Frontal cortex is representative of early AD, as it does not become involved by tau tangles until late in AD. Entorhinal total tau was significantly higher in the amnestic mild cognitive impairment group when compared to AD, but only after accounting for AD associated synaptic changes. Alterations in AMPA GluR1 observed in the entorhinal cortex, but not middle frontal cortex, suggest that pTau231 mislocalization and aggregation in postsynaptic structures may impair glutamatergic signaling by promoting AMPA receptor dephosphorylation and internalization. CONCLUSION: Results highlight the potential effectiveness of early pharmacological interventions targeting pTau231 accumulation at the postsynaptic density.

Movement Disorder Specialists Survey Regarding Use of Telemedicine During the COVID-19 Pandemic.

Aim: To assess the overall satisfaction level of movement disorder specialists using a virtual platform during the COVID-19 pandemic. Methods: This was a multicenter cross-sectional survey for a 6-month period during the beginning of the COVID-19 pandemic. Movement disorder specialists, who utilized telehealth visits from March 2020 to August 2020, were included. The study surveys, including provider's satisfaction with the care that they were able to provide and visit quality, were completed by the provider after each visit. Results: A total of 206 visits, provided by movement disorder specialists, were analyzed. Zoom was the most popular platform used for remote visits (70, 34%). A backup platform was not needed in the majority of movement disorder visits (171, 83%). The majority of physicians were very satisfied or satisfied with the care provided (72.9%) and visit quality (61%). Conclusions: The satisfaction level of specialists using telemedicine during COVID-19 was high despite having encounters with elderly patients with cognitive impairment or lacking advanced skills with technology.

Long term follow-up results of deep brain stimulation of the Globus pallidus interna in pediatric patients with DYT1-positive dystonia.

OBJECTIVES: Primary generalized dystonia (PGD) due to heterozygous torsin 1A (TOR1A) gene mutation (DYT1) is a childhood onset dystonia with rapid deterioration of symptoms, leading to severe disability in adolescence. Globus pallidus interna deep brain stimulation (GPi-DBS) has been shown to provide significant improvement in these cases. METHODS: This was a retrospective study of TOR1A mutation positive dystonia patients, conducted at a university hospital from 2006 to 2018. Burke-Fahn-Marsden Dystonia Rating Scale (BFM-DRS) was used to evaluate dystonia severity before and after surgery. Emergence of postsurgical parkinsonian symptoms was evaluated using the Unified Parkinson Disease Rating Scale (UPDRS) part III. Montreal Cognitive Assessment (MOCA) was applied to assess cognitive dysfunction. SPSS version 18 was used for data analysis. RESULTS: Eleven patients entered for analysis with an average age of 22.36 (±3.35) years (range: 18-28). Seven patients (63.6 %) were female. Mean follow-up period was 8.72 (±0.87). Difference between baseline and most recent BFM scores was significant (disability: 10.5 ±4.52 versus 2.09 (±3.20), P: 0.001; severity: 48.45 (±17.88) versus 9.36 (±10.47), P<0.001). The mean MOCA and UPDRS III scores after 7-9 years of DBS were 27.18 (±2.99), and 6.09 (±4.15), respectively. CONCLUSION: Our experience confirms that GPi-DBS in pediatric patients with DYT1 dystonia is overall successful, with significant and long-lasting positive effects on motor and cognitive functions. There was no prominent side effect in long-term follow up.

Weight loss and weight gain in Parkinson disease.

INTRODUCTION: Parkinson disease (PD) has been associated with both weight loss and gain in different stages of the disease. Our study aimed to determine the prevalence and associations with weight change over two years based on 3% and 5% weight change. METHODS: In this longitudinal analysis, weight at baseline and follow-up was used to classify patients into groups of weight loss, stable, and weight gain. Differences between these groups at baseline and then with change over time were tested. RESULTS: The sample was 668 patients with mean(SD) age 66.1(10) and disease duration 5.3(5.4) years. Using 3% weight change criteria: 32.6% lost, 23.1% gained, and 55.7% had stable weight. Using 5% criteria: 22.6% lost, 15.7% gained, and 61.7% had stable weight. Age was associated with both 3% and 5% change in weight. Other associations with 5% weight change were disease duration, Total and Motor Unified Parkinson's Disease Rating Scale, Older Americans Resource and Services disability, and Hoehn & Yahr staging. The effects of 3% weight loss on Motor UPDRS, IADLs, and depression, and the effects of 5% weight loss on IADLs remained statistically significant when controlling for baseline differences in age, levodopa use, and Total UPDRS. CONCLUSION: PD patients are more likely to experience 3% than 5% weight change and this lower threshold of weight change was associated with greater disease severity and disability over time. Attention to more subtle weight change may help identify those at greater risk of disability.

Midbrain area for differentiating Parkinson's disease from progressive supranuclear palsy.

OBJECTIVES: We aimed to investigate the values of midbrain area in diagnosing Parkinson's Disease (PD) and progressive supranuclear palsy (PSP) by using transcranial sonography (TCS). Disease duration effect on brain sonographic findings could decrease the accuracy of TCS in PD and PSP patients. We reduced the disease duration effect on sonographic differences found between PD and PSP patients by using multivariate analysis. PATIENTS AND METHODS: Patients with clinical diagnosis of PSP and PD were recruited. We used SonoSite Edge II Ultrasound system to measure midbrain area, diameter of third ventricle and substantia nigra echogenicity. Diagnostic value of each measured area in sonography was estimated regarding its power for diagnosing PD or PSP. Independent sample t-test, Regression analysis and receiver operating characteristic (ROC) curve were performed using SPSS software. RESULTS: Of 35 patients, 18 were PD and 17 PSP cases. The mean midbrain area was 4.86 ± 0.71cm2 in PD patients and 3.61 ± 0.85cm2 in those with PSP (P < 0.005). Regression for reducing the effect of disease duration on midbrain area variances between patients with PD and PSP revealed a significant P value (P < 0.005, Adjusted R2 = 0.36). The sensitivity and specificity of midbrain area in diagnosing PD were 83.3% and 70.6% respectively. The sensitivity of the third ventricle size in diagnosing PSP was 82% although its specificity was 62%. CONCLUSION: Midbrain area in patients with PD was wider than those with PSP that was not affected by disease duration. Midbrain area was the most accurate index for diagnosing PD by TCS although third ventricle size was the most sensitive one for diagnosing PSP.

The role of Candida albicans in the severity of multiple sclerosis.

The purpose of this study was to compare the specific activity of proteinase A in Candida albicans (C. albicans) between multiple sclerosis (MS) patients and controls. A total of 135 and 100 C. albicans strains were isolated from superficial surfaces of MS patients and healthy controls. Analytical models (regression and neural network) were applied to predict the severity of MS considering specific enzyme activity (SEA) and other factors which affect the expanded disability status scale (EDSS). The SEA of C. albicans in MS patients (3466.95 ± 277.25 µmol min-1 mg-1 ) was significantly more than that of healthy controls (1108.98 ± 294.51 µmol min-1 mg-1 ) that was confirmed by regression model (P < 0.001). The SEA had a positive correlation with the severity of MS (P < 0.001, r = 0.65). Analytical models showed that SEA played the most important role (among all included factors that affect on EDSS) in the severity of MS. The SEA of C. albicans in MS patients was significantly more than the healthy controls. The results suggest that the level of SEA of proteinase A and probably the capacity of C. albicans isolates to invade the host tissue is associated with the severity of MS.

A novel effect of Noscapine on patients with massive ischemic stroke: A pseudo-randomized clinical trial.

BACKGROUND: Massive ischemic stroke causes significant mortality and morbidity in stroke patients. The main treatments for massive ischemic stroke are recombinant tissue plasminogen activator (rtPA), craniotomy, and endovascular interventions. Due to destructive effects of bradykinin on the nervous system in ischemic stroke, it seems reasonable that using Noscapine as a Bradykinin antagonist may improve patients' outcome after ischemic stroke. The effect of Noscapine on massive ischemic stroke was shown by the previous pilot study by our group. This pseudo-randomized clinical trial study was designed to assess the result of the pilot study. METHODS: Patients who had clinical symptoms or computed tomography scan indicative of massive stroke (in full middle cerebral artery territory) were entered to the study. The cases received the drugs according to their turns in emergency ward (pseudo-randomized). The patient group received Noscapine, and the control group received common supportive treatments. The patients and data analyzer were blinded about the data. At the end of the study, to adjust confounding variables we used logistic regression. RESULTS: After 1-month follow-up, 16 patients in the control group and 11 patients in the case group expired (P = 0.193). Analyzing the data extracted from Rankin scale and Barthel index check lists, revealed no significant differences in the two groups. CONCLUSION: Despite the absence of significant statistical results in our study, the reduction rate of 16% for mortality rate in Noscapine recipients is clinically remarkable and motivates future studies with larger sample sizes.

Raphe nuclei echogenicity changes in major depression.

BACKGROUND: Major depression is a common disorder with great social and individual burdens. Transcranial sonography (TCS) is a useful and noninvasive measure for assessment of normal and impaired brain parenchyma. The brainstem raphe nuclei are in close association with dorsocaudal limbic system and plays an important role in depression. In this study we compared the echogenicity of the raphe nuclei in patients with major depressive disorder and the control group. METHODS: Thirty patients suffering from depression, diagnosed by a psychiatrist, and 30 cases of similar age and sex were entered into the case and control groups respectively. Semi-structural clinical conversation was done according to the DSM IV-TR in order to confirm the depression by the psychiatrist member of the group. Echogenicity of the brainstem raphe nuclei was assessed by a trained neurologist using TCS. To compare the mean echogenicity between the two groups independent sample t-test was used. In order to assess the strength of association between the disease and the echogenicity, odds ratio was also calculated. RESULTS: The echogenicity of the brainstem raphe nuclei was significantly decreased in depressed patients (36.7%) in comparison with the control group (10% ) (p= 0.015, OR= 5.21). CONCLUSION: Echogenicity of the brainstem raphe nuclei in patients with depression is significantly lower than normal population. To confirm the results, we recommend a meta analysis considering previous articles' results.

The higher prevalence of non-right handers among patients with restless leg syndrome.

Restless leg syndrome (RLS) is a common disorder described as an urge to move the legs. Dopamine, the main neuro-transmitter in the pathophysiology of RLS, is likely related to the development of brain laterality and human handedness. We aimed to compare the prevalence of RLS in right and non-right handers. A checklist including Edinburgh questioner for handedness, questions for RLS diagnosis and basic characteristics was filled out by a sample of population. The exclusion criteria included prolonged use of dopaminergic or psychologic drugs and having diseases with similar symptoms to RLS. The frequency of non-right handers in RLS patients was compared with the controls by Chi square test. P value less than 0.05 was considered significant. 164 persons were divided into RLS patients (69) and non-RLS controls (95). There was no significant difference between demographic characteristics. The prevalence of non-right handers in RLS patients was significantly more than non-RLS controls (P: 0.03). Our finding regarding the higher prevalence of non-right handers in RLS patients needs more justifications based on neuroscientists' guides. RLS as a disease in which dopaminergic system involves is highly assumed to be linked with handedness. This is just a hypothesis that impaired modulation of immune system in left handers may be accompanied with lower dopamine levels in RLS.

Retinal nerve changes in patients with tremor dominant and akinetic rigid Parkinson's disease.

Parkinson disease is a multisystem neurodegenerative disease which involves not only basal ganglia and extrapyramidal system but also many other neurologic systems such as retinal ganglion cells. Optical coherence tomography (OCT) is a non-invasive method for assessment of retinal nerve fiber layer (RNFL) thickness and its changes in different diseases. To evaluate the RNFL thickness in patients with Parkinson disease (PD), we performed OCT in patients with PD and compared it with a control group. From October 2010 to July 2011, 27 PD patients (54 eyes) and 25 healthy persons (50 eyes) were entered to this analytical cross-sectional study according to the defined criteria. PD patients were categorized into two groups "akinetic rigid (AR) and tremor dominant (TD)". RNFL was divided into four quadrants and was assessed by OCT. Afterwards; the data were analyzed by bivariate and multivariate models. The RNFL thickness in PD was significantly lower than the control group. Also, the thicknesses of inferior and nasal quadrants of RNFL in TD group were significantly more than AR group. According to these findings, OCT can be used as a sensitive and objective marker for assessment of early neurodegenerative changes of PD and early initiation of neuroprotective treatments. Future studies with adequate sample sizes are recommended to investigate interactions between age, distribution of the disease and type of PD as well as the effects of individual factors.

A study of factors associated with cerebral venous thrombosis.

Cerebral venous thrombosis (CVT) is an uncommon but important cause of stroke. Since there are few number of studies about the factors associated with CVT, we aimed to perform a study on Iranian patients, during a 12-year period (1997-2010) and assessed the risk factors, mortality rate, symptoms and signs, imaging and seasonal distribution. This study was a retrospective cross sectional study conducted in Rasul-e-Akram Hospital of Tehran University of Medical Sciences. The hospital is a referral neurology center for west, south and east parts of the capital city. The patients' data were extracted from the documents and entered to a self-designed checklist including probable risk factors, sequels, involved venous and also demographic characteristics. From 62 patients, 85.5% of the patients were female. Most of the patients were between 25 and 35 years old. Superior sagittal sinus was involved in 35 patients. Generalized seizure in the expired group (7 patients) was significantly more than the alive group (P = 0.017). There was a significant relationship between intracranial hemorrhage and mortality rate and between the site of thrombosis and level of consciousness. There was also a significant relationship between fasting and pregnancy with seizure in these patients. Although most of the patients presented in spring and autumn, majority of the expired cases were reported in autumn. This study can help defining risk factors, symptoms, and predicting risk factors of seizure in patients with CVT. We suggest future studies based on gathering data for meta-analysis.

An epidemiologic study of factors associated with nasal septum deviation by computed tomography scan: a cross sectional study.

BACKGROUND: Sinusitis is an inflammation of the paranasal sinuses that can be caused by anatomic variations of the nasal cavity and paranasal sinuses. In this study we aimed to find the relationship between sinusitis and septal deviation (SeD) and concha bullosa. METHODS: Two trained resident of ENT evaluated sinus CT scans of 463 cases presenting with nasal obstruction or chronic sinusitis symptoms from April 2011 to December 2011. CT scans were checked for the presence of conchae bullosa and the degree of septal deviation. The severity of sinusitis was evaluated according to the Lund Mackay criteria. The frequency of patients with different degrees of SeD and different grades of chronic sinusitis were studied. RESULTS: Of 463 cases, 47% had septal deviation. Concha bullosa was seen in 16.8% of the patients in the left side and 27.6% of them in the right side. There was no significant relationship between the presence of concha bullosa and the severity of sinusitis. Also the P value of analytical tests between the severity of sinusitis, osteomeatal involvement and the degree of septal deviation was not significant. Analysis of the relationship between the presence of SeD (either to right or left) and the severity of sinusitis in different sinuses revealed no significant P value. CONCLUSIONS: By this study, the relationship between concha bullosa in osteomeatal complex and the severity of sinusitis was not cleared. No relationship was found between the severity of sinusitis, osteomeatal involvement and the degree of septal deviation. Also SeD (either to right or left) was not found to be associated with the severity of sinusitis in different sinuses.

Lycopene an adjunctive therapy for Helicobacter pylori eradication: a quasi-control trial.

Although some herbal remedies in association with vitamin therapy have been investigated in eradicating HP, no research has been done to investigate the effects of lycopene it. Our aim was to understand if lycopene could be effective in eradication of HP. In this parallel group quasi-control trial, a total of 54 patients whose diagnosis of HP had been confirmed by rapid urease test (RUT) were enrolled. Group 1 received the standard 4-drug therapy to eradicate HP (Metronidazole 500 mg/BD, Amoxicillin 1g/BD, Omeprazole 20mg/BD, and Bismuth 240 mg/BD) and group 2 received the same regimen in association with Lycopene (30 mg/daily). One month after the initiation of the treatment, the patients were evaluated for HP eradication by RUT. Although eradication rate was higher in the second group, bivariate analysis showed no significant statistical difference between the two groups. In contrast with other nutrients, it seems that Lycopene does not have any significant effects on eradicating HP in comparison with the standard antibiotic therapy. The prevalence of HP is in association with socioeconomic situation, so the patients in different studies should be paid more attention about their own life style. We recommend that more studies can be designed by considering control group and placebo administration.

Porous high-density polyethylene in facial reconstruction and revision rhinoplasty: a prospective cohort study.

INTRODUCTION: Initial methods which used human tissues as reconstruction materials caused different problems including rejection, limited shapes and infection. In 1970s, PHDPE (Medpor®) was introduced by its exclusive advantageous including no donor site morbidity, easily shaped and the minimal foreign body reaction. Hereby, we report our experience of using Medpor® in facial reconstruction especially in frontal reconstruction and orbital rim with a large sample size. METHODS: This study was a prospective cohort study. Surgical techniques included using Medpor® in reconstruction of lamina papiracea (LP) (15 patients), frontal bone (15 patients), orbital rim (18 patients) and open rhinoplasty (8 patients). All interventions on LP were performed by endoscopic procedures. All frontal operations were carried out by bicoronal incision. In orbital defects, we used subciliary incision. RESULTS: From all 56 patients, 1 case had primitive neuroectodermal tumor (PNET) of maxillary sinus. In that case, reconstruction of inferior orbital rim was not successful and extrusion was occurred after radiotherapy. In rhinoplasty and other experiences no extrusion or infection were detected within the next 1 to 3 years of follow up. There were not any palpable and visible irregularities under the skin in our experiences. CONCLUSIONS: In this study the patients did not experience any complications during the follow up periods and the satisfaction was remarkable. Gathering these data gives rise to future review studies which can provide more organized evidences for replacing classic reconstructive methods by the presented material.

Detection of helicobacter pylori in benign laryngeal lesions by polymerase chain reaction: a cross sectional study.

BACKGROUND: Although Helicobacter Pylori (HP) was detected in some cases of chronic laryngitis, the results were not confirmed by polymerase chain reaction (PCR). By this time, it has not been found in laryngeal lesions by in house PCR, the most sensitive method for detecting the genome tracks. Regarding the previous results and also few numbers of studies about the presence of HP in benign laryngeal lesions, specifically by PCR, we aimed to investigate the presence of HP in benign laryngeal lesions by in-house PCR. METHODS: The samples were taken from 55 patients with benign laryngeal lesions and frozen in -20°C. One milliliter (ml) of lysis buffer was added to 100 mg (mg) of each sample and the tube was placed in 56°C overnight. Then DNA extraction was carried out. RESULTS: To find HP DNA, in-house PCR was performed that revealed 5 positive results among 55 patients with benign laryngeal lesions. Of them, 3 were polyp, 1 was nodule and 1 was papilloma. CONCLUSION: Although the number of positive results was not a lot in this study, it was in contrast with previous studies which could not find any HP tracks in benign laryngeal lesions by other methods. More studies about the prevalence of HP in benign laryngeal lesions improve judging about the effect of this infection on benign laryngeal lesions.

Air column in esophagus and symptoms of gastroesophageal reflux disease.

BACKGROUND: During imaging of the normal esophagus, air is often detected. The purpose of this study was to determine the correlation between the appearance of air bubbles on imaging and Gastroesophageal Reflux Disease (GERD) symptoms. METHODS: The cross-sectional imaging study was conducted at Rasole Akram Hospital, Tehran, Iran. A total of 44 patients underwent X-ray computed tomography (CT) scanning; the presence of air in the esophagus and visible on CT imaging was scrutinized. RESULTS: The average age of the subjects was 59 and the male to female ratio was 0.83. We found a significant relationship between the presence of GERD symptoms, the size of air bubbles and esophageal dilation (ED) on the CT scan. CONCLUSIONS: Air bubbles in the esophagus may be seen frequently in CT scans, but their size and location can vary. The GERD symptoms can arise when a small diameter air column is present within the esophagus, especially in the middle and lower parts.

Prevalence of diabetes mellitus and impaired fasting blood glucose in patients with Lichen Planus.

BACKGROUND: The relationship between Lichen Planus (LP) and diabetes was studied previously, but the results were in conflict. The aim of this study was to find the prevalence of diabetes mellitus (DM) in patients with LP among Iranian patients. METHODS: In this study, 80 patients with LP were enrolled. They referred to dermatology clinic of our hospital during one year. A self-designed checklist for the study included duration of the disease, the pattern of the distribution of lichenoid lesions and fasting blood sugar (FBS). RESULTS: From 80 patients with LP, 16 (20%) had diabetes. Also, 14 patients (17.5%) had impaired fasting glucose. The mean age of diabetic patients was significantly higher than non-diabetic group (p=0.039). In addition, the duration of LP in patients with DM was significantly higher than non-diabetic patients (p=0.024). CONCLUSION: In our study, we saw a high prevalence of DM among patients with LP. Comparing our findings with the overall prevalence of DM in Iran, there was a significant difference between the prevalence of DM among patients with LP and the overall prevalence (p=0.001). Regarding our findings screening for FBS in patients with LP is required in Iran.

Fulminant multiple sclerosis (MS).

Fulminant multiple sclerosis (MS) is the most malignant form of MS which usually leads to death in few weeks. Although it can be accompanied by optic neuritis (ON), but long interval between ON and the grave onset has not been reported. Fulminant MS usually occurs as the first onset and previous ON is not common. We report a rare case of 30-year-old woman with a history of ON 1 year ago. The rapid deterioration to vegetative state followed by a seizure and previous ON differentiated this case from previous reported cases. The differential diagnosis of a rapidly progressive leucoencephalopathy in this patient includes inflammatory, vascular, infectious and toxic disorders. Regarding the previous history of optic neuritis with positive brain MRI (multiple T2 hyperintense lesions in white matter) in our patient, multiple sclerosis is the most probable diagnosis. More effective treatments, such as plasmapheresis and cyclophosphamide, that influenced on the prognosis of some previous patients could be useful, but should be performed before progressive brain atrophy emerges.
