Investigating the mortality trend of gastrointestinal cancers in Babol, North Iran (2013-2021).

BACKGROUND AND AIM: This study aims to examine the mortality rate and trend of gastrointestinal cancers, particularly gastric cancer, as the leading cause of death among cancers in northern Iran over a 9-year period. In light of the changing incidence and mortality rates of cancer in Iran and around the world, the importance of these diseases in people's lives, and the necessity of updating and monitoring the trend of cancer mortality, we have decided to report on the mortality trend of gastrointestinal cancers, based on crude and age-standardized rates. METHOD: This study is a cross-sectional examination of deaths caused by gastrointestinal cancers in Babol city, Iran, between 2013 and 2021. Data was collected from the cause of death registration and classification system of Babol University of Medical Sciences. Population estimation was obtained from the latest census reports. The crude and age-standardized mortality rates and trends of the cancers were calculated. RESULTS: Overall, there were 1345 deaths from gastrointestinal cancers with an average age of 69.11 ± 14.25 years. The crude and age-standardized rates of these cancers rose from 24.1 to 20.1 per hundred thousand people in 2012 to 29.5 and 25.5 per hundred thousand people, respectively. This trend became more prevalent significantly with the increase of each decade of age for both men (P-value Trend = 0.002) and women (P-value Trend = 0.012). An analysis of gastrointestinal cancers revealed a decreasing trend for cancers of the small intestine, an increasing trend for cancers of the colon, pancreas, and gallbladder, and a stable trend for the remaining cancers over the study period. CONCLUSION: The age-standardized rate and the number of gastrointestinal cancers is rising, highlighting the importance of preventative measures such as screening, increasing public awareness, and appropriate diagnostic methods.

Saliva and Serum Acetylcholinesterase Activity in Multiple Sclerosis.

Multiple sclerosis is mediated by the immune system that damages the myelin sheath. Most patients experience inflammation. Since one of the factors that have a role in reducing inflammation is acetylcholine, and according to the benefits of saliva, in this study, the level of salivary and serum cholinesterase activity in patients with multiple sclerosis and healthy were evaluated. Thirty women with multiple sclerosis who were hospitalized in the neurology ward of Imam Reza and Hazrat Rasoul Hospitals and 30 healthy females participated in the study. The severity of multiple sclerosis was calculated by expanded disability status scale (EDSS). Saliva and serum samples were collected in the morning. Cholinesterase activity was assessed by a photometric method. The mean cholinesterase activity in stimulated and unstimulated saliva and serum significantly reduced in the multiple sclerosis group. The cutoff for differentiation of multiple sclerosis patients from healthy individuals by assessing cholinesterase activity (IU/L) was 3577 in serum, 241 in unstimulated saliva, and 266 in stimulated saliva. It seems that cholinesterase activity decreases in patients with multiple sclerosis.

The study of trends in mortality of respiratory system cancers in Babol, North of Iran (2013-2021).

Background: In Iran, cancers are known as the second leading cause of death, among which respiratory system cancers are particularly important because lung cancer is the second most common cause of death in this country. This study aimed to estimate the crude and age-standardized mortality and its trends during 9 years in the Northern city of Iran, Babol. Methods: In this cross-sectional study, all the recorded deaths due to respiratory system cancers in Babol during the years 2013-2021 on the Classification of Causes of Deaths and Death Registration System of Babol University of Medical Sciences were taken into consideration, and the population estimate was based on the latest census. Finally, the crude and age-standardized rates of mortality and trends of cancer incidents were calculated. Results: In general, 393 deaths with an overall mean age of 67.8±3.9 years have happened due to respiratory system cancers. The crude and standardized rates of respiratory system cancers increased from 6.5 and 5.5 per hundred thousand people in 2013 to 9.1 and 7.8 per hundred thousand people in 2021, respectively. With each decade in age, their trends increased significantly in men (p=0.024) and remained constant in women (p=0.262). In examining the trend of respiratory system cancers, we found an increasing trend for lung cancer and a constant trend for larynx and oropharynx cancers. There was also a decreasing trend for hypopharyngeal cancer. Conclusions: The age-standardized rate and trend of respiratory system cancers are increasing. Therefore, it is important to prevent their prevalence by reducing the risk factors and increasing the general awareness of risks and timely diagnosis.

Preliminary report of Iranian Registry of Alzheimer's disease in Tehran province: A cross-sectional study in Iran.

Background and Aims: Alzheimer's disease (AD) is the main cause of dementia and over the 55 million people live with dementia worldwide. We aimed to establish the first database called the Iranian Alzheimer's Disease Registry to create a powerful source for future research in the country. In this report, the design and early results of the Iranian Alzheimer's Disease Registry will be described. Methods: We performed this multicenter investigation and patients' data including age, sex, educational level, disease status, Mini-Mental State Examination (MMSE), and Geriatric Depression Scale (GDS) from 2018 to 2021 were collected, registered, and analyzed by GraphPad Prism software. Results: Totally 200 AD patients were registered in our database. 107 (54%) were women and age of 147 (74%) were over 65. The mean age for men and women was 76.20 ± 8.29 and 76.40 ± 8.83 years, respectively. 132 (66%) were married and 64 (32%) were illiterate. Also, 94 (47%) were in the moderate stage of disease, and 150 (75%) lived at home together with their families. The most frequent neurological comorbidity was psychosis (n = 72, 36%), while hypertension was the most common non-neurological comorbidity (n = 104, 52%). The GDS score of women in the mild stage (5.23 ± 2.9 vs. 6.9 ± 2.6, p = 0.005) and moderate stage (5.36 ± 2.4 vs. 8.21 ± 2.06, p = <0.001) of the disease was significantly greater than men. In univariate analysis, MMSC score was remarkably associated with stroke (ß = -2.25, p = 0.03), psychosis (ß = -2.18, p = 0.009), diabetes (ß = 3.6, p = <0.001), and hypercholesteremia (ß = 1.67, p = 0.05). Also, the MMSE score showed a notable relationship with stroke (ß = -2.13, p = 0.05) and diabetes (ß = 3.26, p = <0.001) in multivariate analysis. Conclusion: Iranian Alzheimer's Disease Registry can provide epidemiological and clinical data to use for purposes such as enhancing the current AD management in clinical centers, filling the gaps in preventative care, and establishing effective monitoring and cure for the disease.

Huntington's disease and neurovascular structure of retina.

BACKGROUND: Retinal biomarkers in neurodegenerative disorders have attracted much attention in recent years. Recent studies have reported visual dysfunction in Huntington's disease (HD). However, little is known about retinal structural changes in HD. METHODS: A total of 50 subjects, including 25 motor-manifest HD patients and 25 gender- and age-matched controls, were enrolled. Unified Huntington's Disease Rating Score-Motor part was assessed in HD patients. Spectral-domain Optical Coherence Tomography (SD-OCT) was used to evaluate the macular thickness and peripapillary retinal nerve fiber layer (pRNFL). Superficial and deep capillary plexus densities were measured using OCT angiography (OCTA). To account for inter-eye correlation, generalized estimating equation (GEE) model was used. RESULTS: HD patients had a significant reduction in macular thickness in both inner and outer superior sectors and the inferior outer sector. Inferior pRNFLs were significantly decreased in thickness. There was no significant difference in retinal capillary plexus density between the two groups. Age and disease duration were negatively correlated with macular thickness in HD patients. However, the severity of motor involvement was not correlated with SD-OCT or OCTA parameters. CONCLUSIONS: We observed attenuated pRNFL and macular retinal thickness in patients with HD, independent of macular capillary plexus parameters. It can support the hypothesis that the retina may be a potential biomarker for monitoring the neurodegenerative process in HD.

Rituximab and risk of COVID-19 infection and its severity in patients with MS and NMOSD.

BACKGROUND: Choosing a safe disease modifying therapy during the COVID-19 pandemic is challenging. This case series study was conducted to determine the incidence rate and the course of Covid-19 infection in MS/NMOSD patients treated with Rituximab. METHODS: In this study, we designed a web-based questionnaire. Baseline information such as patient- reported walking disability, total number of Rituximab infusions received, delayed injections, occurrence of any relapse, and the use of corticosteroids during the pandemic were collected. Also, information regarding the Covid-19 pandemic such as adherence to self-isolation, any recent exposure to an infected individual and the presence of suggestive symptoms were collected. In case of positive test results, patients were grouped into 2 categories; mild to moderate and seriously ill and outcomes were evaluated as favorable (improved/ discharged) and unfavorable (expired). RESULTS: Two hundred fifty-eight patients with Multiple Sclerosis were enrolled in this study, 9 of the subjects (3.4%) were confirmed positive for Covid-19, five of which required hospitalizations (55.5%), two patients required ICU admission (22.2%) and 2 two patients died (22.2%). None of these patients ever mentioned using corticosteroids during the pandemic. In comparison to MS patients who were not receiving disease modifying therapy (DMT), our study indicated a higher incidence of Covid-19 infection, higher ratio of serious illness and a higher fatality ratio. CONCLUSIONS: Rituximab seems not to be safe enough during the pandemic.

Disability and its association with psychological factors in multiple sclerosis patients.

BACKGROUND: Multiple Sclerosis (MS) is a neurological, and immune-mediated demyelinating disease. Psychological factors in MS disease and psychosocial interventions based on these factors have a major role in the adjustment of MS patients toward their disease. The aim of the study was to compare the psychological components of happiness, psychological well-being, love of life, meaning in life, and somatic health between MS patients with low Expanded Disability Status Scale (EDSS) scores and MS patients with higher EDSS scores. METHOD: A sample of 128 patients with MS was recruited. Patients were administered the EDSS, the Self-Rating Scale of Happiness (SRH), the World Health Organization-five Well-Being Index (WHO-5), the Love of Life Scale (LLS), the Meaning in Life Questionnaire (MLQ) and the Patient Health Questionnaire-15 (PHQ-15). Patients with EDSS>3 (cases) and EDSS≤3 (controls) were compared. RESULTS: The cases had lower scores for happiness, love of life, psychological well-being, meaning in life, the present of meaning in life subscale, and somatic health, compared with the controls. The differences between cases and controls remained statistically significant after controlling for age and sex. CONCLUSION: Positive health promotion and education intervention programs to reduce disability and increase MS patients' well-being should be one of the priorities in the Iran healthcare system for MS patients. Therapists should take these components into account when working with MS patients with moderate and severe disability.

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.

Impact of anticholinergic drugs withdrawal on motor function in patients with Parkinson's disease.

OBJECTIVES: Physicians have prescribed anticholinergic agents as monotherapy or adjuvant therapy in patients with Parkinson's disease for decades. However, these medications can cause many adverse effects including gait freezing and falling. Herein we assessed the effects of anticholinergic medications on motor function, freezing of gait and falling in a group of patients with PD. PATIENTS AND METHODS: This prospective study evaluated the effect of gradual discontinuation of anticholinergics on motor function in 131 outpatients with Parkinson's disease. We assessed patients' motor function at baseline six and twelve months later using the UPDRS-III. We also evaluated freezing of gait and falling in patients using UPDRS-II part 14 and 13 respectively. The anticholinergics were tapered and gradually discontinued and additional levodopa doses were added as patients needed. RESULTS: 131patients successfully discontinued their anticholinergic medications. Stopping anticholinergics significantly improved the motor symptoms in PD patients as reflected in the change between the mean (±SD) UPDRS-III score of 36.85(±11.5) at the baseline to 32.51(±11.4) and 31.43 (±11.3) after six and twelve months (P < 0.001). The mean (±SD) scores of freezing of gait (FOG)significantly changed from 1.34(±1) to 1.17(±1) and 0.6(±0.7) and for falling down from 0.62(±0.8) to 0.5 (±0.8) and 0.29(±0.5) respectively (p-value of <0.001). CONCLUSION: Our finding demonstrated an improvement in motor function and FOG and falling incidences in PD patients, after discontinuation of anticholinergic drugs. As motor complications adversely affect the quality of life in PD patients, clinicians must be careful with the unnecessary use of anticholinergic drugs in their treatment strategies.

A novel decision tree approach to predict the probability of conversion to multiple sclerosis in Iranian patients with optic neuritis.

BACKGROUND: assessing the risk of conversion to multiple sclerosis (MS) in patients with optic neuritis (ON) has been the topic of numerous studies. However, since the risk factors differ from population to population, the extension of conclusions is a matter of debate. This study focused on the Iranian patients with optic neuritis and assessed the probability of conversion to multiple sclerosis by using a machine-based learning decision tree. METHODS: in this retrospective, observational study the medical records of patients with optic neuritis from 2008 to 2018 were reviewed. Baseline vision, the treatment modality, magnetic resonance imaging (MRI) findings, and patients' demographics were gathered to evaluate the odds of each factor for conversion to MS. The decision tree was then obtained from these data based on their specificity and sensitivity to predict the probability of conversion to MS. RESULTS: the overall conversion rate to MS was 42.2% (117/277). 63.1 percent of patients had abnormal MRIs at baseline. The presence of white matter plaque had the highest odds for the conversion followed by the positive history of optic neuritis attack and gender. The regression tree showed that the presence of plaque was the most important predicting factor that increased the probability of conversion from 16 to 51 percent. CONCLUSION: the decision tree could predict the probability of conversion to MS by considering multiple risk factors with acceptable precision.

Evolution and resolution of brain involvement associated with SARS- CoV2 infection: A close Clinical - Paraclinical follow up study of a case.

The new severe acute respiratory syndrome- coronavirus 2 is reported to affect the nervous system. Among the reports of the various neurological manifestations, there are a few documented specific processes to explain the neurological signs. We report a para-infectious encephalitis patient with clinical, laboratory, and imaging findings during evolution and convalescence phase of coronavirus infection. This comprehensive overview can illuminate the natural history of similar cases. As the two previously reported cases of encephalitis associated with this virus were not widely discussed regarding the treatment, we share our successful approach and add some recommendations about this new and scarce entity.

Randomized control trial of evaluation of Clemastine effects on visual evoked potential, nerve fiber layer and ganglion cell layer complex in patients with optic neuritis.

OBJECTIVES: Optic neuritis (ON) is the most common cause of optic neuropathy; typically presenting with a unilateral visual loss in young adults, with incidence of 1-5 in 100,000 per year. We evaluated the effect of Clemastine, a first-generation and CNS (central nervous system)-penetrant H1 receptor antagonist on visual evoked potential (VEP), retinal nerve fibre layer (RNFL) and ganglion cell layer (GCL) complex in patients with optic neuritis. PATIENTS AND METHODS: This is a prospective comparative interventional case series in 25 patients with acute optic neuritis. Patients were randomly assigned to group 1 (treated with Clemastine 1 mg orally twice a day for 90 days; 16 patients) or group 2 (received placebo for 90 days; 9 patients) and both groups received standard treatment of optic neuritis. We recorded VEP and peripapillary OCT (optical coherence tomography) of patients before and after three months of treatment. RESULTS: In contrast to patients treated with Clemastine, RNFL thickness loss between base line phase and after three months follow up in control group were statistically significant in temporal, supra temporal, Infrotemporal and almost global sections of RNFL map. The reduction in GCL thickness between base line phase and after three months follow up in control group were significant, while it did not reach significance in treatment group except in inferior region. CONCLUSION: In contrast to treatment group, RNFL and GCL thickness of most quadrants are decreased significantly after three months in patients with ON in control group. In contrast to control group, p100 wave's amplitude recovered in a significant manner in treatment group.

Parkinsonism management issues in a patient with exhausted subthalamic deep brain stimulation battery, stricken by severe acute respiratory syndrome coronavirus 2.

Background: Nowadays, many neurological conditions, including Parkinson's disease (PD), are treated with deep brain stimulation (DBS). Life-threatening consequences can occur from DBS hardware failure or sudden implantable pulse generator (IPG) battery depletion. This issue may potentially worsen in concomitance with medical or infectious conditions, requiring stronger emergency management. Methods: We present here a 58 year-old PD patient with DBS, whose IPG replacement surgery was complicated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and we report management of this patient along with recommendations for patients with similar situation. Results: As the newly-emerged coronavirus disease 2019 (COVID-19) is now announced to be pandemic, new protocols and specific measures for each individual group of patients with chronic diseases seem obligatory. Regarding our recent experience with a patient suffering from PD, on DBS treatment, who needed hospitalization, we felt useful to share our experience as a recommended protocol for similar patients in the time of current pandemic. Conclusion: Close monitoring of laboratory and clinical signs should be warranted in patients with PD awaiting IPG replacement in order to be prepared in these novel conditions that may precipitate an akinetic crisis/dystonic storm and to prevent life-threatening complications during the current pandemic.

Correlations between developmental test of visual perception-adolescent and adult and visual evoked potential in people with multiple sclerosis.

Background: Optic neuritis (ON) is a common visual sign in multiple sclerosis (MS). Although ON is recovered in most cases, other visual functions such as visual perception are affected and are not fully recovered. The aim of this study is to investigate the relationship between visual evoked potential (VEP) P100 and N70 latencies and visual perception using the Developmental Test of Visual Perception-Adolescent and Adult (DTVP-A) in people with MS. Methods: In this cross-sectional study, 24 people with ON due to MS, aged 18-50 years old took part. In order to assess the visual perception and optic nerve conductivity, the DTVP-A and the VEP were accomplished, respectively. Pearson's product-moment correlation coefficient was used to analyze the data. Results: There was a significant negative correlation between right VEP P100 latency and total score of DTVP-A (r = -0.450, P < 0.05) as well as a significant negative correlation between right VEP P100 latency with visual-motor integration (VMI) subtest of DTVP-A (r = -0.485, P < 0.05). Conclusion: The visual perception has an important role in safety and independent daily activities. Therefore, determining the related factors is essential. Although the findings of the current study revealed a moderate statistical correlation between visual perception and right VEP P100 latency, the small sample size might limit the generalization of our findings; therefore, further study is required to confirm our results.

Stroke in supplementary motor area mimicking functional disorder: a case report.

Supplementary motor area, the posterior third of the medial aspect of superior frontal gyrus, is known to be a heterogeneous area in function. It is involved in self-initiated motor movements, planning and sequencing the motor action, response inhibition, and bimanual movements. Blood supply for supplementary motor area is mostly by callosomarginal branch of anterior cerebral artery. Stroke in anterior cerebral artery territory is relatively uncommon, moreover, isolated supplementary motor area stroke is a rare entity. Supplementary motor area stroke, as a syndrome, has variable symptoms consisting of impairment of volitional movements, hemineglect, dyspraxia of contralateral limbs, impaired muscle tone, mutism and contralateral weakness. As symptoms are sometimes ambivalent, patients may be misdiagnosed as functional disorder and lose the chance for immediate adequate treatments such as thrombolysis. We report a 59-year-old man with previous history for myocardial infarction, referred to emergency room with an acute dense right-side hemiplegia, positive Hoover sign, asymmetrical Babinski responses and intermittent ability to move his arm in some specific reflex actions despite plegia. Since brain computed tomography scan was unremarkable we could not be sure whether his symptoms were organic or functional until a diffusion weighted imaging of magnetic resonance imaging elucidated the situation. To our knowledge, there is only one case report in the literature prior to ours, presenting a supplementary motor area stroke patient, mimicking functional disorder. Therefore, we may claim our report to be the second reported case.

Bilateral Cavernous Sinus Thrombosis as First Manifestation of Primary Burkitt Lymphoma of the Thyroid Gland.

Cavernous sinus thrombosis (CST) is a rare condition that is usually associated with infections, pregnancy, vasculitis and some types of medication, such as the contraceptive pill and paraneoplastic. Primary Burkitt lymphoma (PBL) of the thyroid gland is very uncommon and the clinical description of such cases has been largely limited to case reports. In this paper, we present a case of CST as the first manifestation of PBL of the thyroid gland. To the best of our knowledge, our patient is the first case report of PBL of the thyroid gland that presents with bilateral CST.

Diagnostic Value of D-Dimer's Serum Level in Iranian Patients with Cerebral Venous Thrombosis.

Cerebral venous thrombosis (CVT) is a long-term debilitating vascular brain disease with high morbidity and mortality. It may be associated with rise in D-dimer level. The aim of this study was to examine this potential association and identify the critical D-dimer cut-off level corresponding to increase the risk of CVT. This case-control study was conducted on two groups of patients with and without CVT attending the Rasool Akram Hospital (Iran) during 2014 and 2015. D-dimer levels were measured by the rapid sensitive D-dimer assay. Data were analyzed by Spearman's correlation coefficient test, independent-samples t-test, backward-selection multiple linear regression and multiple binary logistic regression analyses. Sensitivity-specificity tests were used to detect D-dimer cut-off for CVT. Differences between the D-dimer levels of the case and control groups were significant (P<0.001). It showed that each level of increase in the number of symptoms could increase the risk of thrombosis occurrence for about 3.5 times. All symptom types except for headache were associated with D-dimer level, while headache has negative association with D-dimer level. D-dimer cut-off point for CVT diagnosis was estimated at 350 ng/mg. We concluded that D-dimer serum level significantly rises in CVT patients. A rounded cut-off point of 350 ng/mg can be used as a diagnostic criterion for CVT prediction.
