ObjectiveTo analyze the effects of pregnancy on neuromyelitis optica spectrum disorder (NMOSD) according to patients' serostatus and immunosuppressive therapy (IST).MethodsWe performed a retrospective multicenter international study on patients with NMOSD. Patients were tested for aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) antibodies (Ab). Informative pregnancies were reported when NMOSD onset occurred before or during pregnancy or up to 12 months postpartum. The mean annualized relapse rate (ARR) was calculated for the 12 months before conception, for each trimester of pregnancy, and postpartum. Events such as miscarriage, abortion, and preeclampsia were reported. IST was considered if taken in the 3 months before or during pregnancy.ResultsWe included 89 pregnancies (46 with AQP4-Ab, 30 with MOG-Ab, and 13 without either Ab) in 58 patients with NMOSD. Compared to the prepregnancy period, the ARR was lower during pregnancy in each serostatus group and higher during the postpartum period in patients with AQP4-Ab (p < 0.01). Forty-eight percent (n = 31) of pregnancies occurred during IST and these patients presented fewer relapses during pregnancy and the 12 months postpartum than untreated patients (26% vs 53%, p = 0.04). Miscarriages occurred in 10 (11%) pregnancies, and were mainly in patients with AQP4-Ab (with or without IST) and a previous history of miscarriage. Preeclampsia was reported in 2 (2%) patients who were AQP4-Ab-positive.ConclusionWe found a rebound in the ARR during the first postpartum trimester that was higher than the prepregnancy period only in AQP4-Ab-positive patients. Taking IST just before or during pregnancy reduces the risk of relapses in these conditions.

Neuromyelitis optica spectrum disorder is uncommon in children, and often seronegative for aquaporin-4 immunoglobulin G (AQP4-IgG). We conducted a retrospective study of 67 children presenting to a single Australian center with acquired demyelinating syndromes over a 7-year period. All patients were tested for AQP4-IgG. Five children (7.5%) had neuromyelitis optica spectrum disorder. One child was seropositive for AQP4-IgG (1.5%) and had a relapsing disease course with mild residual deficits. She also had a concomitant motor axonal neuropathy that improved with immunosuppressive therapy. Of the remaining 4 children, 3 had a monophasic course and 1 a relapsing course. Two were tested for anti–myelin oligodendrocyte glycoprotein (anti-MOG) antibody and both were seropositive. This study confirms that neuromyelitis optica spectrum disorder is uncommon in children, and that AQP4-IgG seropositivity is rare. Anti-MOG antibodies should be tested in children with neuromyelitis optica spectrum disorder.

Background and objective. Preeclampsia is a multisystemic disorder, which involves the placenta, liver, blood, neurological and cardiovascular systems. It is one of the leading causes of maternal and fetal morbidity and mortality. This study aimed at describing the characteristic features for mothers who had severe preeclampsia and to know the complications during puerperium. Methods. A prospective study conducted over a period from February 2009 up to November 2009 involving 100 pre-eclampsia patients admitted and delivered in Aljalaa Maternity Hospital, Tripoli, Libya. Results. The patients mean age was 33.3 +5.9 years. The mean gestational age at admission time was 36.8+3.2 weeks and 64% of them were term. 58% of the patients with severe preeclampsia had a positive family history of chronic hypertension whereas 42% of patients had a previous history of preeclampsia. 40% of patients were primigravida. The mean systolic blood pressure at admission was 164+15.4 mmHg and the mean diastolic pressure was 113+6 mmHg. The common symptoms were headache, abdominal pain, and blurred vision (54%, 37%, and 31% respectively), whereas 9% of the patients presented with the eclamptic fit. The pregnancy in 66% patients ended by caesarean section, 78% of them were emergency caesarean section. The birth weight of 13% of new-borns was less than 1500 grams. Furthermore, 10% diagnosed with intrauterine fetal death (IUFD) antenatally and 9% died after admission to nursery intensive care unit post-delivery. Conclusion. the effects of hypertensive disorder associated with pregnancy could be prevented by close antenatal care particularly for whose had previous history of preeclampsia. In addition; early recognition and adequate treatment, and timely delivery can prevent preeclampsia and will improve maternal and neonatal outcomes.

Background: The absence of Aquaporin-4 Antibody (AQP4-Ab) in a fraction of the Neuromyelitis Optica Spectrum Disorder (NMOSD) patients has led to a search for other serologic markers. Myelin Oligodendrocyte Glycoprotein (MOG) is a protein component of the myelin sheets encapsulating the neural fibers. Objectives: We aimed to compare the presence and levels of anti-MOG (Ig-G) in a group of seronegative NMOSD patients with a healthy control group. Materials & Methods: In this cross-sectional study, 30 NMOSD patients with negative AQP-Ab status, who were referred to the Neurology Clinic of Kashani University Hospital in Isfahan City, Iran, from March 2015 to March 2016, and 26 healthy controls were consecutively recruited. Their baseline demographic and clinical data were recorded. Serum anti-MOG levels were measured in both groups. The obtained data were analyzed using the Student t-test, Mann-Whitney U, and Chisquare test in SPSS V. 18. Results: The anti-MOG test results were statistically higher in patients (n=12, 37.5%) compared to controls (n=0, 0%) (P<0.0001). The level of anti-MOG in Healthy Control (HC) was higher compared to patients with negative anti-MOG (P<0.0001) and was lower than patients with positive anti-MOG (P<0.0001). Conclusion: Our study showed that nearly one-third of seronegative NMOSD patients were positive for MOG-Ab. Further studies are needed to assess the characteristics and outcome of these patients.

Background: Tramadol is a widely prescribed analgesic and due to its opioid-like effects, the potential for abuse of tramadol is noticeable. Besides, the complications of tramadol abuse have become a public health concern. This study aimed to investigate the affecting factors on the seizure, as one of the most common complications of tramadol consumption. Methods: A total number of 64 patients from 315 patients who were referred to Sina Hospital, Tabriz, Iran because of tramadol toxicity were included in this 9 months cross-sectional retrospective study. Results: There were 52 males and 12 females in the study. The seizure happened in 53.1% of the subjects and the Mean±SD time between tramadol consumption and seizure was 5.9±7.36 hours. There was no significant association between seizure and sex, age, the dose of tramadol, and previous tramadol consumption history. A significant association was seen between the dose of tramadol and the time of seizure. Conclusion: Seizure that happens due to tramadol overdose is not dependent on sex, age, and previous history of tramadol consumption. As the dose of tramadol is higher, the seizure happens later. More research is needed to understand why the seizure occurs later in higher doses.

Background. Early diagnosis of cerebral venous sinus thrombosis (CVST) associated with reproductive health-related risk factors (RHRF) including pregnancy, puerperium, and oral contraceptive (OC) use can prevent severe neurological sequelae; thus, the symptoms must be documented in detail for each group. Methods. Out of 1144 patients with CVST, a total of 777 women were enrolled from a multicenter for the study of cerebral venous sinus thrombosis (VENOST). Demographic, biochemical, clinical, and radiological aspects were compared for 324 cases with RHRF and 453 cases without RHRF. Results. The mean age of the RHRF (-) group (43.2 ± 13 years) was significantly higher than of the RHRF (+) group (34±9 years). A previous history of deep venous thrombosis (3%), isolated cavernous sinus involvement (1%), cranial neuropathy (13%), comorbid malignancy (7%), and its disability scores after 12 months (9%) were significantly higher in the RHRF (-) group. The RHRF (+) group consisted of 44% cases of puerperium, 33% cases of OC users and 23% of pregnant women. The mean age was found to be higher in OC users (38±9 years). A previous history of deep venous thrombosis was slightly higher in the pregnancy subgroup (4%). Epileptic seizures were more common in the puerperium group (44%). Conclusion. The results of our study indicate that the risk of CSVT increases parallel to age, OC use, and puerperium period. In addition, when considering the frequency of findings and symptoms, epileptic seizures in the puerperium subgroup of the RHRF (+) group and malignancies in the RHRF (-) group may accompany the CSVT. In daily practice, predicting these risks for the CSVT and early recognition of the symptoms will provide significant benefits to patients.

Neuromyelitis Optica Spectrum Disorder

Neuromyelitis optica spectrum disorder (NMOSD) and anti-myelin oligodendrocyte glycoprotein (anti-MOG) syndromes are immune-mediated inflammatory conditions of the central nervous system that frequently involve the optic nerves and the spinal cord. Because of their similar clinical manifestations and habitual relapsing course they are frequently confounded with multiple sclerosis (MS). Early and accurate diagnosis of these distinct conditions is relevant as they have different treatments. Some agents used for MS treatment may be deleterious to NMOSD. NMOSD is frequently associated with antibodies which target aquaporin-4 (AQP4), the most abundant water channel in the CNS, located in the astrocytic processes at the blood-brain barrier (BBB). On the other hand, anti-MOG syndromes result from damage to myelin oligodendrocyte glycoprotein (MOG), expressed on surfaces of oligodendrocytes and myelin sheaths. Acute transverse myelitis with longitudinally extensive lesion on spinal MRI is the most frequent inaugural manifestation of NMOSD, usually followed by optic neuritis. Other core clinical characteristics include area postrema syndrome, brainstem, diencephalic and cerebral symptoms that may be associated with typical MRI abnormalities. Acute disseminated encephalomyelitis and bilateral or recurrent optic neuritis are the most frequent anti-MOG syndromes in children and adults, respectively. Attacks are usually treated with steroids, and relapses prevention with immunosuppressive drugs. Promising emerging therapies for NMOSD include monoclonal antibodies and tolerization.

Introduction. The relevance of carbohydrate metabolism studying in patients with Cushing disease can be explained by frequent occurrence of glucose metabolism disturbances on the one hand, and difficulties in glucose-lowering therapy in these patients on the other. The effectiveness of hyperglycaemia treatment may be reduced due to difficulties in remission / cure of the underlying disease, as well as to the use of specific drug-therapy, leading to the hyperglycaemia. There is a growing interest in research aimed at studying the role of incretin system in the pathogenesis of secondary hyperglycemia associated with neuroendocrine diseases recently.Methods. A total of 20 patients with Cushing disease were included, (19 female and 1 male), the mean age was 37.5 years (18-69). All of the patients were diagnosed with Cushing disease for the first time (using urinary free cortisol levels and MRI-data); none of them had a history of previous drug therapy, radiotherapy or pituitary surgery. The mean HbA1c level was 5,8% (5,3-6,2). All patients underwent OGTT, during which glucose, glucagon, GLP1, GLP2, GIP, ghrelin were measured at 0, 30 and 120 min respectively. The control group included 21 patients without previous history of carbohydrate metabolism disturbances. After OGTT 57% were presented without any carbohydrate metabolism disturbances, 28,57% presented with prediabetes and 14,43% were diagnosed with diabetes.Results. After glucose levels analyzing 40% of patients were diagnosed with early carbohydrate metabolism disturbances ,15% were diagnosed with diabetes. After glucose intake a slight inrease in glucagon levels with a peak by 30’ (p=0,001) compared to gradually decreasing levels in controls was observed . The levels of GIP during OGTT were not significantly different compared to control group. GLP-1 and GLP-2 levels were significantly higher compared to controls (p=0,017 and p<0,001 respectively) with peak levels at 30’. Ghrelin levels were also significantly higher compared to controls (p=0,013)Conclusion. Incretins levels can be possible markers of specific carbohydrate metabolism disturbances in patients with Cushing disease and presumably will help to differentiate steroid diabetes from T2DM. Further investigations needed to prove these speculations.

Background: Preoperative apprehension is a widespread global problem. This anxiety and apprehension can significantly affect all aspects of anesthesia and surgery. Thus, it is essential to detect and address the patient's anxiety to assist in recovery after surgery and improve the patient's outcome. Materials and Methods: This is a cross-sectional study conducted over one year in the allied hospitals of Rawalpindi Medical University (RMU). Our sample size was 380 preoperative patients, who were selected by convenience sampling. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) was used.Results: The overall prevalence of anxiety was 30.5%, while the prevalence of information requirement was 33.2%. The mean total APAIS was 12.73±8.56, the mean anxiety subscore was 8.25±5.58, and the mean need for information subscore was 4.48±3.16. A statistically significant difference was found in the scores of the patients based on age, gender, education, type of anesthesia, and type of surgery (p< 0.05). The previous history of anesthesia and the presence of comorbidities did not bring a significant difference in the scores of the patients (p>0.05). Postoperative pain was the most important concern, found in 32% of the patients. Conclusion: Younger age group, female gender, having no formal education, surgery under regional anesthesia, and undergoing C-section, IOL implantation and septoplasty are associated with higher preoperative anxiety, while the presence of comorbidities and previous history of anesthesia are factors that do not significantly affect preoperative anxiety in our population.

Abstract Introduction: Corona virus disease 2019 (COVID-19) pandemic has become a globally challenging issue after its emergence in December 2019 from Wuhan, China. Despite its common presentation as respiratory distress, patients with COVID-19 have also shown neurological manifestation especially stroke. Therefore, the authors sought to determine the etiology, underlying risk factors, and outcomes among patients with COVID-19 presenting with stroke. Methods: We conducted a systematic review of the electronic database (PubMed, Google Scholar, Scopus, Medline, EMBASE, and Cochrane library) using different MeSH terms from January 2000 to June 2020. Results: A total of 39 patients with stroke from 6 studies were included. The mean age of our included patients was 61.4±14.2 years. Majority of the patients (92.3%) with COVID-19 had ischemic stroke, 5.1% had hemorrhagic stroke, and 2.6% had cerebral venous thrombosis at the time of initial clinical presentation. Almost all of the patients presented had underlying risk factors predisposing to stroke which included, diabetes mellitus, hyperlipidemia, hypertension, and previous history of cerebrovascular disease. 51.2% of the included patients infected with COVID-19 with stroke died, while remaining patients were either discharged home or transferred to a rehabilitation unit. Conclusion: Exploring the neurological manifestation in terms of stroke among patients with COVID-19 is a step towards better understanding of the virus, preventing further spread, and treating the patients affected by this pandemic.
