The Impact of the COVID-19 Lockdown on the Quality of Life in Chronic Neurological Diseases: The Results of a COVQoL-CND Study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic and lockdown period may induce an impairment in quality of life (QoL), disruption in treatment (DIT), and posttraumatic stress disorder (PTSD) in chronic neurological diseases (CNDs). To reach this information, a multicenter, cross-sectional study (COVQoL-CND) was planned. Parkinson's disease (PD), headache (HA), multiple sclerosis (MS), epilepsy (EP), polyneuropathy (PNP), and cerebrovascular disease (CVD) were selected as the CND. METHODS: The COVQoL-CND study includes demographic data, the World Health Organization Quality of Life short form (WHOQOL-BREF), and Impact of Event Scale-Revised (IES-R) forms. RESULTS: The mean age of a total of 577 patients was 49 ± 17 (19-87 years), and the ratio of female/male was 352/225. The mean age of patients with PD, HA, MS, EP, PNP, and CVD were 65 ± 11, 39 ± 12, 38 ± 10, 47 ± 17, 61 ± 12, and 60 ± 15 years, respectively. The IES-R scores were found to be higher in the younger group, those with comorbid disease, contacted with CO-VID-19 patients, or diagnosed with COVID-19. In the group with a high IES-R score, the rate of DIT was found to be high. IES-R scores were negatively correlated with QoL. IES-R total scores were found highest in the CVD group and lowest in the PD group. The ratio of DIT was found highest in the PNP group and the lowest in the EP group. Contact with CO-VID-19 patients was high in the EP and HA group. CONCLUSIONS: The results of the COVQoL-CND study showed that lockdown causes posttraumatic stress and deterioration in the QoL in CND.

Comparison of conventional and modern methods in determining ischemic stroke etiology by general and stroke neurologists

Background/aim: This study aimed to investigate the consistency between stroke and general neurologists in subtype assignment using the Trial of ORG-10172 in Acute Stroke Treatment (TOAST) and Causative Classification of Stroke (CCS) systems. Materials and methods: Fifty consecutive acute ischemic stroke patients admitted to the stroke unit were recruited. Patients were classified by two stroke and two general neurologists, each from different medical centers, according to TOAST followed by the CCS. Each neurologist was assessed for consistency and compliance in pairs. Concordance among all four neurologists was investigated and evaluated using the kappa (ĸ) value. Results: The kappa (ĸ) value of diagnostic compliance between stroke neurologists was 0.61 (95% CI: 0.45­0.77) for TOAST and 0.78 (95% CI: 0.62­0.94) for CSS-5. The kappa (ĸ) value was 0.64 (95% CI: 0.48­0.80) for TOAST and 0.75 (95% CI: 0.60­0.91) for CCS-5 for general neurologists. Compliance was moderate [ĸ: 0.59 (95% CI: 0.52­0.65)] for TOAST and was strong [ĸ: 0.75 (95% CI: 0.68­0.81)] for CCS-5 for all 4 neurologists. 'Cardioembolism' (91.04%) had the highest compliance in both systems. The frequency of the group with 'undetermined etiologies' was less in the CCS (26%) compared to TOAST. Conclusion: The CCS system improved compliance in both stroke and general neurologists compared with TOAST. This suggests that the automatic, evidence-based, easily reproducible CCS system was superior to the TOAST system.

Gender differences in older adults with chronic migraine in Turkey.

AIM: Chronic migraine is a growing and disabling subtype of migraine with different risk factors and clinical features, even in older adults. We sought to define and differentiate clinical features of chronic migraine in older adults. We also aimed to compare major clinical features of chronic migraine in older adults with those in younger people of both sexes. METHODS: We used electronic dataset (Turkish Headache Database) from 13 tertiary headache centers in Turkey. Electronic dataset included detailed headache-defining features according to ICHD-II criteria based on face-to-face interviews and examination by a headache specialist. Using statistical methods, clinical variables of chronic migraine in older adults were compared with those of younger adults. We included 915 patients with chronic migraine (mean age 43.80 ± 13.95 years); 83.3% were females. In total, 301 patients (32.9%) with chronic migraine aged >50 years were compared with 614 patients aged <50 years. RESULTS: There was no significant change in men with increasing age. However, duration of headache history, severity of attacks, previous histories of motion sickness and positive family history of headaches were significantly different in women with increasing age. Further sex-related differences have been shown in parameters such as attack duration, quality and associated nausea. CONCLUSION: Chronic migraine is an infrequent type of migraine and shows age-related changes in some phenotypic characteristics, such as severity of attacks, especially in women aged older than 50 years. Furthermore, positive family history of headaches and history of motion sickness increase the likelihood of developing chronic migraine in older women, indicating involvement of some gender-related, but as-yet unknown, genetic factors.

Desensitization in interferon-beta1a allergy: a case report.

We report a 41-year-old patient with multiple sclerosis (MS) who was successfully desensitized after she developed non-injection-site urticaria and angioedema due to interferon (IFN)-beta1a. Although a few cases of urticaria and anaphylaxis have been reported in the literature, to our knowledge this is the first report of a successful desensitization with IFN-beta1a. Desensitization with IFN-beta1a allowed us to continue with the administration of interferon-beta, which is a mainstay in treatment for MS.

[In vitro activity of fosfomycin trometamol in the treatment of Escherichia coli related uncomplicated urinary tract infections]. / Escherichia coli nedenli komplike olmamis üriner sistem enfeksiyonlarinda fosfomisin trometamolün in vitro etkinligi.

Although in certain countries in Europe fosfomycin trometamol (FT) has been used for many years, in Turkey FT has become available in recent years. FT has a broad-spectrum activity against most of gram-positive and gram-negative bacteria. In this study, we aimed to evaluate the effect of FT, a new alternative antimicrobial agent in the treatment of patients with Escherichia coli related uncomplicated lower urinary tract infection (UTI). For this purpose, between May 2007-July 2008, FT susceptibility of 771 nonduplicate E. coli strains, isolated from urine samples of patients with uncomplicated lower UTI (bacteria > or = 10(5) cfu/mL), was determined by disk diffusion method according to Clinical and Laboratory Standarts Institute (CLSI) criteria. Simultaneously, extended-spectrum beta-lactamase (ESBL) detection was performed by double disk synergy test in all isolates. Among all E. coli isolates, FT resistance rate was 0.4% (3/771) and ESBL positivity was 19.5% (150/771). The rates of ESBL producing strains isolated from inpatients and outpatients were 34.1% (70/205) and 14.1% (80/566), respectively, and the difference was found statistically significant (p = 0.0001). Although resistance to FT was not detected in non-ESBL producing E. coli isolates (n = 621), FT resistance rate was 2% (3/150) in ESBL producers. As far as the current literature was concerned this was the largest scale study investigating the activity of FT in Turkey. Resistance to antimicrobials that had been used frequently as therapeutic options for the treatment of E. coli related UTIs, has been increasing. In the present study high susceptibility rates to FT was determined for urinary E. coli isolates. In conclusion, these data suggest that FT may be a good alternative for the treatment of uncomplicated UTIs as a first line antimicrobial agent.

[Antimicrobial resistance profiles of community-acquired uropathogenic Escherichia coli isolates during 2004-2006 in a training hospital in Istanbul]. / Istanbul'da bir arastirma hastanesinde 2004-2006 yillari arasinda izole edilen toplumdan kazanilmis üropatojen Escherichia coli izolatlarinin antibiyotik direnç profilleri.

In order to reveal the antimicrobial resistance profiles against first-line antimicrobial agents in community-acquired acute uncomplicated urinary tract infections (UTIs), resistance patterns were determined for 1664 Escherichia coli strains collected between 2004 and 2006 in GATA Haydarpasa Training Hospital, Istanbul, Turkey. Of the isolates 38.2% were found to be susceptible to all of the tested antimicrobial agents, while the resistance rate to single antibiotic was 13.5%. Highest prevalence of antimicrobial resistance was observed for ampicillin (AMP) (49%), followed by amoxycillin-clavulanic acid (AMC) (34%), sulphamethoxazole/trimethoprim (SXT) (34%) and ciprofloxacin (CIP) (18%). The rate of multidrug resistant isolates was 33.5% and 48.4% of them were co-resistant. Resistance against two antimicrobials was identified in 244, against three antimicrobials in 205, against four antimicrobials in 160, against five antimicrobials in 63 and against six antimicrobials in 23 strains. Most frequent phenotypes indicating resistance against two, three and four antimicrobial agents were AMP/AMC (5.7%), AMP/AMC/SXT (5.4%) and AMP/AMC/cephazolin/SXT (2.6%), respectively. Extended spectrum beta-lactamase (ESBL) activity was detected in 40 (2.4%) of the isolates. Most prominent increases in resistance prevalence during the study period were observed for AMP (from 52% to 63%), AMC (from 33% to 45%) and CIP (from 15% to 22%). These results show that resistance to AMP, AMC and SXT are frequent in community-acquired E. coli strains and empirical initial treatment with these agents will most probably be inappropriate in our region.

[Investigation of methicillin resistance and aminoglycoside modifying enzyme genes in hospital staphylococci by multiplex-polymerase chain reaction]. / Hastane izolati stafilokoklarda metisiliN diRenç ve aminoglikozid modifiye edici enzim genlerinin multipleks-polimeraz zincir reaksiyonu ile aratirilmasi.

This study was conducted to investigate the presence of methicillin and aminoglycoside resistance encoding genes by multiplex-polymerase chain reaction (PCR) and by phenotypic methods in staphylococci isolated from inpatients' clinical specimens. The presence of aac(6')1aph(2"), aph(3')-IIIa and ant(4)-Ia genes encoding aminoglycoside modifying enzymes (AME) and mecA gene encoding methicillin resistance were genotypically investigated. A total of 19 S. aureus and 30 coagulase negative staphylococci (CNS) were tested. Thirty four (69.4%) of the isolates were found to be resistant to oxacillin with disk diffusion test, 33 (97%) of which were found to harbour mecA gene. The correspondance between oxacillin resistance and presence of mecA gene was found to be 100% in S. aureus isolates, while it was 95.7% in CNS. Twenty two (44.9%), 7 (14.3%) and 2 (4.1%) isolates were found to harbour aac(6')/aph(2"), aph(3')-IIIa and ant(4)-/a AME genes, respectively. At least one or more AME genes were detected in 72.7% of mecA positive isolates.

The efficacy and safety of dipyrone (Novalgin) tablets in the treatment of acute migraine attacks: a double-blind, cross-over, randomized, placebo-controlled, multi-center study.

Dipyrone, an effective analgesic drug, is widely used in the management of headache. However, few studies have evaluated its efficacy and safety in migraine. We aimed to assess the efficacy and safety of 1 g dipyrone (Novalgin, two 500 mg tablets) on pain and related symptoms in acute migraine attacks with or without aura in a double-blind, cross-over, randomized, placebo-controlled, multi-center study design. Seventy-three migraine with or without aura patients, diagnosed according to the IHS criteria, were randomized to receive dipyrone (for 2 attacks) and placebo (for 1 attack). Pain intensity was measured on a four-point verbal pain scale before and 1, 2, 4 and 24 hours after drug intake. Significant improvement of pain was achieved with dipyrone compared to placebo at all time points measured. Both patient and physician evaluations were significantly in favor of dipyrone. Side effects were few and trivial in both groups. We conclude that dipyrone is an effective, safe and cost-effective option in acute migraine management.

[Comparison of electrocardiographic abnormalities in patients with ischemic and hemorrhagic stroke]. / Iskemik ve Hemorajik Inmeli Hastalarda Elektrokardiyografik Anormalliklerin Karsilastirilmasi.

OBJECTIVE: The aim of this study was to compare the electrocardiographic (ECG) abnormalities in patients with acute ischemic and hemorrhagic stroke who had no history of heart disease. METHODS: During 12 months, 222 consecutive stroke patients were enrolled in this study. Of them 162 had ischemic stroke and 60 had hemorrhagic stroke. Frequency of arrhythmias and ECG changes were compared between two stroke groups. Electrocardiographic abnormalities included ischemia-like changes (ST-segment depression or elevation, abnormal T and U waves), QTc prolongation and arrhythmias. RESULTS: Ischemic stroke patients were elder than hemorrhagic ones (64+/-14 years vs. 57+/-13 years, p=0.003). Other clinical characteristics were comparable in both groups. Ischemia-like ECG changes were found in 65% of ischemic stroke patients while they were observed in 57% of hemorrhagic stroke patients (p=0.33). Atrial fibrillation was more frequent in ischemic stroke than in hemorrhagic stroke (34% vs. 13%, p=0.01) patients. Individually, other ECG abnormalities were not different in both groups. With relation of ECG abnormalities to location of the brain lesion, there was a trend in favor of involvement of the temporal, frontal and parietal lobes. CONCLUSION: Regardless stroke-related lesion, ECG abnormalities can be seen frequently in stroke patients without primary heart disease. They can lead to diagnostic and therapeutic difficulties for cardiologists and neurologists.

Ankylosing spondylitis and multiple sclerosis in an HLA-B27 negative patient.

A 41-year-old man presented with vertigo and gait disturbance. He gave a 10-year history of definite ankylosing spondylitis with low back pain, limitation of spinal mobility, decreased chest expansion and radiological evidence of bilateral sacroiliitis. The vertigo attacks started 3 years before and he had insidious evolution of bilateral leg weakness, increased muscle tension and walking disability during the past 2 years. The HLA haplotypes of the patient were A2, A33, B14, B49, Bw4, Bw6, Cw7 and he was HLA-B27 negative. The axial and sagittal cranial magnetic resonance imaging (MRI) showed multiple foci of increased signal intensity in the periventricular white matter and cerebellar hemispheres, suggesting a demyelinating disease process. The MRI of the spine showed centromedullar high intensity lesions at C7, Th7-8, Th9-10 levels. The diagnosis was definite MS (primary progressive MS) as the patient had insidious neurological progression, CSF evidence of inthrathecal production of oligoclonal bands, conduction defects at VEP, multiple brain and additional spinal cord lesions on MRI and continued progression for more than 1 year.

Effect of botulinum-A toxin to cremaster muscle: an experimental study.

OBJECTIVE: A controversy exists on the definition, etiology and treatment of the retractile testes. In the present experimental study, we aimed to show the effect of botulinum-A toxin (Botox) on cremasteric muscle of a rat, and whether it may be an alternative to surgical treatment of retractile testis. METHODS: Ten Wistar rats were used in the study. By stimulating cremasteric reflex, five compound muscle action potentials (CMAP) of the right and left cremasteric muscles of each rat were recorded using surface electrodes. Intramuscular injection of botulinum-A toxin was done to the right side. Saline was injected to the left cremasteric muscles, and the left side also served as control. CMAP of the cremasteric muscles were recorded 45 days after the injection. Statistical analysis was done using Wilcoxon Signed rank test. RESULTS: Mean CMAP of the right side was 3.25+/-1.39 microV before the injection and 0.44+/-0.25 microV after botulinum-A toxin injection. The difference was statistically significant (p<0.05). Mean CMAP on the left side was 3.48+/-0.32 microV and 3.14+/-1.12 microV at baseline and the end of the study, respectively. The difference was not statistically significant (p>0.05). CONCLUSION: The botulinum-A toxin paralyzes the cremasteric muscles of the rats. As cremasteric hypertonicity is accepted as one of the reasons for retractile testes, botulinum-A toxin injection to cremasteric muscles may be helpful in diagnosis and may be an alternative to surgical treatment of this pathology in repeated dosages. Long-term evaluation of this paralysis is necessary.

Hyperbaric oxygen ameliorates bacterial translocation in rats with mechanical intestinal obstruction.

PURPOSE: The aim of this study was to demonstrate bacterial translocation after experimentally induced intestinal obstruction as well as investigate the preventive effects of hyperbaric oxygen on obstruction-induced bacterial translocation in rats. METHODS: Forty Wistar-albino male and female rats were used. Although no procedure was done in the control group (n = 8), hyperbaric oxygen treatment under 2.5 atm absolute for 90 minutes daily was applied for two days in the hyperbaric oxygen group (n = 8). In the sham group (n = 8), after laparotomy the small bowel was only handled gently, and tissue sampling was done 48 hours later. In the obstruction group (n = 8) the ileum was ligated by 5-0 polypropylene just 5 cm proximal to the ileocecal valve. In the obstruction and hyperbaric oxygen group (n = 8), after obstruction hyperbaric oxygen treatment was applied. Forty-eight hours after the procedures, tissue samples from small bowel, mesenteric lymph nodes, spleen, and liver were taken and 1 ml of blood from the portal vein was withdrawn. All samples were cultured for microbiologic examination. RESULTS: Hyperbaric oxygen treatment significantly reduced the endogenous bacterial overgrowth in the small intestine of normal rats. Endogenous bacteria in the small intestine were significantly increased in the obstruction group, and the presence of bacterial overgrowth was proven by bacterial presence on mesenteric lymph nodes, spleen, liver, and blood. Hyperbaric oxygen treatment significantly reduced the endogenous bacterial overgrowth in the small intestine and prevented the bacterial translocation almost completely in obstruction-induced rats. CONCLUSIONS: Intestinal obstruction causes bacterial overgrowth and translocation. Hyperbaric oxygen treatment prevents the bacterial translocation effectively.

Hyperbaric oxygen prevents bacterial translocation in thermally injured rats.

This study was designed to evaluate the effects of hyperbaric oxygen (HBO2) on intestinal microflora and bacterial translocation (BT) caused by experimentally induced thermal injury in rats. Rats were separated into four groups, namely, HBO2 group, thermal injury (TI) group, TI + HBO2 group, and control group. All groups were further separated into short-term (2 days) and long-term (7 days) treatment or injury groups. Control group was neither exposed to thermal injury nor was given any treatment. Thirty percent second-degree thermal burn was induced on the dorsal body part of the rats in TI groups. In the HBO2 groups, rats received HBO2 treatment either without TI or following TI induction, for 2 and 7 days, respectively. Sampling from tissues and portal vein was performed on day 3 in the short-term groups and on day 8 in the long-term groups. Samples were cultured for identification of bacteria and colony counts. HBO2 treatment significantly reduced the colony counts of endogenous microflora in distal ileum of healthy rats (p < .05), while TI significantly increased the colony counts of endogenous microflora in distal ileum in short and long-term TI groups (p < .05). Presence of bacterial translocation was proven by bacterial isolation in mesenteric lymph nodes, liver, spleen and blood. Both short- and long-term HBO2 treatment following TI significantly reduced the colony counts of intestinal microflora (p < .05) and prevented bacterial translocation almost completely. It is concluded that thermal injury causes both bacterial overgrowth within intestinal lumen and bacterial translocation across the intestinal wall. HBO2 administration prevents both bacterial overgrowth and translocation.
