Breast cancer knowledge and practices amongst women in Algeria.

The present study aims at investigating how Algerian women feel about Breast Cancer (BC) and Breast Self-Examination (BSE) in terms of knowledge and attitude and to determine the factors associated with performing BSE and its reluctance. We carried out a cross-sectional survey between October 14, 2021 and November 14, 2022, targeting Algerian females aged more than 18years and living in the country using a self-administered questionnaire. A total of 436 participants were involved in this study among which 41.28% were aged between 21 and 30years and 34.86% were aged between 31 and 40years. The average level of correct responses with regard to knowledge about BC was estimated at 51.31%, whereas it was 32.93% concerning knowledge about BC risk factors. Family history was the less reported incriminating factor for developing BC among the asked women (7.34%). Concerning alarming signs of BC, the current study revealed that Algerian women were less knowledgeable about breast dimpling-puckering (44.27%), breast inward traction (50.23%), breast redness (54.13%), and nipple position change (54.13%). In terms of belief in the utility of BSE in the early detection of BC, almost all the participants (97.98%) were convinced of its utility, whereas 96.33% of them showed an interest in learning more about it. In what concerns the early screening tests, approximately, four-fifth of the participant (77.52%) heard about them, while 94.72% believed that its early detection could reduce the disease's severity and mortality. These findings revealed an insufficient level of knowledge concerning BC, especially in regard to its risk factors and some alarming signs as well as a lack of knowledge about BSE and other BC screening tests; hence the necessity of awareness campaigns about this disease that should target categories with the lowest level of knowledge.

How to perceive the insecticide? The Neotropical termite Nasutitermes corniger (Termitidae: Nasutitermitinae) triggers alert behavior after exposure to imidacloprid

In eusocial insects, alarm signaling is used to inform nestmates about threats such as predators, competitors, and pathogens. Such behavior is important for the survival of colonies. However, studies evaluating the effect of insecticides on the alarm in termites have not yet been reported. Here, we inspected the effects of insecticide on alarm communication in Nasutitermes corniger. Specifically, we test the following hypotheses: (1) termite groups exposed to insecticide imidacloprid increase the body shaking movements, displaying an alert behavior; and (2) the alert behavior displayed after exposition to insecticide is dose dependent. Bioassays were conducted evaluating the body shaking movements and walking activity of termite groups exposed and non-exposed to insecticide. Thereafter, body shaking movements were evaluated in groups submitted to different doses of insecticide. In general, exposing termite groups to insecticide resulted in significantly higher body shaking movements compared to non-exposed groups. There was a positive effect of imidacloprid doses on the shaking movements. Walking activity, however, decreases in those groups exposed to the insecticide. Our results demonstrate the existence of ‘insecticide alert behavior’ in N. corniger and it appears to be a previously unrecognized communication mechanism in termites that allows for reducing the intoxication risks in the colony.

Comprehension of own and other species’ alarm calls in sooty mangabey vocal development

Primates understand the meaning of their own and other species’ alarm calls, but little is known about how they acquire such knowledge. Here, we combined direct behavioural observations with playback experiments to investigate two key processes underlying vocal development: comprehension and usage. Especifically, we studied the development of con- and heterospecific alarm call recognition in free-ranging sooty mangabeys, Cercocebus atys, across three age groups: young juveniles (1–2y), old juveniles (3–4y) and adults (> 5y). We observed that, during natural predator encounters, juveniles alarm called to a significantly wider range of species than adults, with evidence of refinement during the first four years of life. In the experiments, we exposed subjects to leopard, eagle and snake alarm calls given by other group members or sympatric Diana monkeys. We found that young juveniles’ locomotor and vocal responses were least appropriate and that they engaged in more social referencing (look at adults when hearing an alarm call) than older individuals, suggesting that vocal competence is obtained via social learning. In conclusion, our results suggest that alarm call comprehension is socially learned during the juvenile stage, with comprehension preceding appropriate usage but no difference between learning their own or other species’ alarm calls.Significance statementUnder natural conditions, animals do not just interact with members of their own species, but usually operate in a network of associated species. However, ontogenetic research on primate communication frequently ignores this significant element. We studied the development of con- and heterospecific alarm call recognition in wild sooty mangabeys. We found that communicative competence was acquired during the juvenile stages, with alarm call comprehension learning preceding appropriate vocal usage and with no clear difference in learning of con- and heterospecific signals. We also found that, during early stages of life, social referencing, a proactive form of social learning, was key in the acquisition of competent alarm call behaviour. Our results show that primates equally learn to interpret alarm calls from their own and other species during their early stages of life and that this learning process is refined as the animals mature.

Clinical and laboratory characteristics of idiopathic inflammatory myositis in Saudi patients: A retrospective study in a single tertiary centre.

Idiopathic inflammatory myositis (IIM) in Saudi patients has been poorly studied owing to the lack of available data. This study aimed to identify the clinical and laboratory features of patients at a single tertiary care center. This retrospective study reviewed the medical records of Prince Sultan Military Medical City, Riyadh, Saudi Arabia to collect clinical and laboratory data between December 2022 and February 2017 as follows: age at disease onset, gender, follow-up duration and disease duration; clinical symptoms; laboratory result; presence and type of myositis-specific autoantibody or myositis-associated autoantibody; and type of immunosuppression, presence of malignancy, disease course, and outcome. There were 26 patients with a mean age of 36.16±13.48, and 84.6% were women. The most prevalent form of IIM was dermatomyositis (n=16, 61.5%), and the most affected organ was the skin. weakness was observed in 25 patients (96.2%), and dysphagia was the most common alarm sign (n=10, 38.5%). During follow-up, the creatine kinase level was elevated at the beginning of the disease and then decreased following treatment, with a mean of 277.73 IU/L. Of the total patients, 17 (68%) were positive for anti-nuclear antibody and 5 (19.2%) were positive for anti-Jo-1. In our patients, dermatomyositis was the most common form of myositis, and skin manifestations were the most prevalent clinical characteristics. None of the patients developed a malignancy or died.

Alzheimers Disease Mechanism in Neuroimmunology Perspective

Among the several neurodegenerative illnesses, one of these is the illness Alzheimer's (AD). it is hard to cure completely for now. To find fresh targets for the therapy of AD, neuroimmunology have been getting attention gradually. Neuroimmunology response, which happened in the central nervous system (CNS), is innate immune response of human. In the AD, microglia activated by damage signals lead to a series of cellular cascade responses. Then, a large number of chemokines and inflammatory cytokines are released by microglial cells. The cytokines have neurotoxic effects on the certain brain areas, causing neuronal degeneration. Since microglia can be activated by tau aggregation in addition to alarm signals, with tau protein aggregation releasing from the degenerative neurons, it provokes a positive feedback mechanism of neuroimmunology in hippocampal area. Microglia mainly play a role of neuroprotective by clearing -amyloid (A) on early stage of AD and have a neurotoxic effects induced by an A-induced phenotypic change on late stage of AD. TREM2 mainly expressed on microglia, it may downregulate the inflammatory response in AD. The review has explained clearly and demonstrated that tau assembly and clearance of A are effective therapeutic targets on AD. In addition, it explained AD nosogenesis from the new view of TREM2 mutations.

Neonatal Outcomes of Term Infants Born with Meconium-Stained Amniotic Fluid.

Background Meconium-stained amniotic fluid (MSAF) is considered an alarming sign of possible fetal compromise and it has recently been reported that neonatal outcome correlates with the degree of meconium thickness. Methods We retrospectively studied 400 term infants allocated in clear amniotic fluid and grade 1, 2, and 3 MSAF groups on the basis of color and thickness of AF. Multivariable logistic regression analysis was performed to evaluate the potential independent effect of delivery with MSAF of different severity on the risk of a composite adverse neonatal outcome. Results We found that delivery with grade 2 (OR 16.82, 95% Cl 2.12-33.52; p = 0.008) and 3 (OR 33.79, 95% Cl 4.24-69.33; p < 0.001) MSAF is independently correlated with the risk of adverse neonatal outcome, such as the occurrence of at least one of the following: need of resuscitation in the delivery room, blood cord pH < 7.100, occurrence of meconium aspiration syndrome (MAS), persistent pulmonary hypertension (PPH), transient tachypnea of the newborn (TTN), acute respiratory distress syndrome (ARDS), hypoxic-ischemic encephalopathy (HIE), and sepsis. Conclusions There is a positive correlation between the severity of amniotic fluid meconium staining and thickness and the outcomes of term infants. Therefore, the evaluation and grading of MSAF during labor is useful in order to plan for the presence of a neonatologist at delivery for immediate and proper neonatal care.

Deep learning health management diagnostics applied to the NIST smoke experiments

Fire is one of the most important hazards that must be considered in advanced nuclear power plant safety assessments. The Nuclear Regulatory Commission (NRC) has developed a large collection of experimental data and associated analyses related to the study of fire safety. In fact, computational fire models are based on quantitative comparisons to those experimental data. During the modeling process, it is important to develop diagnostic health management systems to check the equipment status in fire processes. For example, a fire sensor does not directly provide accurate and complex information that nuclear power plants (NPPs) require. With the assistance of the machine learning method, NPP operators can directly get information on local, ignition, fire material of an NPP fire, instead of temperature, smoke obscuration, gas concentration, and alarm signals. In order to improve the predictive capabilities, this work demonstrates how the deep learning classification method can be used as a diagnostic tool in a specific set of fire experiments. Through a single input from a sensor, the deep learning tool can predict the location and type of fire. This tool also has the capability to provide automatic signals to potential passive fire safety systems. In this work, test data are taken from a specific set of the National Institute of Standards and Technology (NIST) fire experiments in a residential home and analyzed by using the machine learning classification models. The networks chosen for comparison and evaluation are the dense neural networks, convolutional neural networks, long short-term memory networks, and decision trees. The dense neural network and long short-term memory network produce similar levels of accuracy, but the convolutional neural network produces the highest accuracy.

Urinary tract infection with renal abscess

Renal abscess is very rare among intra-abdominal abscesses in children. Ascending infection is the most common cause in children compared to hematogenous spread in adults and Escherichia coli is the main pathogen. Persisting high-grade fever is an alarming sign to intervene and has to be taken care of. Here, we are presenting the case of a 3-year-old boy with Klebsiella urinary tract infection and E. coli renal abscess of 4 cm size. Contrast-enhanced computed tomography abdomen helped in early intervention and management. The child responded very well to parenteral antibiotics and ultrasound-guided percutaneous aspiration.

Selective selfishness in alarm calling behaviour by some members of wintering mixed-species groups of crested tits and willow tits.

Animals adjust their use of alarm calls depending on social environments. We tested whether dominant (adult) and subordinate (juvenile non-kin) male crested tits (Lophophanes cristatus) warn each other and heterospecific willow tits (Poecile montanus) across the wintering season. Birds rarely alarm called when feeding alone. Both adult and juvenile crested tits warned each other in early winter, and adults did so in the middle of wintering season. However, juvenile males rarely warned conspecific adult males in the middle of the winter. Both adult and juvenile males stopped giving alarm calls when feeding together at the end of wintering season. The results suggest that the mid-winter reduction of juvenile alarms could increase the likelihood of successful predator attacks on adults, increasing the chances for juveniles to replace adults and acquire their territories. By contrast, both adult and juvenile males produced alarm calls throughout the season when foraging together with willow tits. Whether juvenile male crested tits could be selectively altering alarm call propensity to endanger adult males, thereby selfishly enhancing their own succession to territory ownership, is discussed. The results add to the understanding of the origin of mixed-species groups and explain the dynamics of social communication. This article is part of the theme issue 'Mixed-species groups and aggregations: shaping ecological and behavioural patterns and processes'.

Causes of gastrointestinal bleeding in children based on endoscopic evaluation at a tertiary care center in Bahrain.

Gastrointestinal bleeding (GIB) is a serious health problem worldwide, particularly during childhood. This can be an alarming sign of an underlying disease. Gastrointestinal endoscopy (GIE) is a safe method for the diagnosis and treatment of GIB in most cases. To determine the incidence, clinical presentation, and outcomes of GIB in children in Bahrain over the last two decades. This was a retrospective cohort review of the medical records of children with GIB who underwent endoscopic procedures in the Pediatric Department at Salmaniya Medical Complex, Bahrain, between 1995 and 2022. Demographic data, clinical presentation, endoscopic findings, and clinical outcomes were recorded. GIB was classified into upper (UGIB) and lower (LGIB) GIB according to the site of bleeding. These were compared with respect to patients' sex, age, and nationality using the Fisher's exact, Pearson's χ 2, or the Mann-Whitney U tests. A total of 250 patients were included in this study. The median incidence was 2.6/100000 per year (interquartile range, 1.4-3.7) with a significantly increasing trend over the last two decades (P < 0.0001). Most patients were males (n = 144, 57.6%). The median age at diagnosis was 9 years (5-11). Ninety-eight (39.2%) patients required upper GIE alone, 41 (16.4%) required colonoscopy alone, and 111 (44.4%) required both. LGIB was more frequent (n = 151, 60.4%) than UGIB (n = 119, 47.6%). There were no significant differences in sex (P = 0.710), age (P = 0.185), or nationality (P = 0.525) between the two groups. Abnormal endoscopic findings were detected in 226 (90.4%) patients. The common cause of LGIB was inflammatory bowel disease (IBD) (n = 77, 30.8%). The common cause of UGIB was gastritis (n = 70, 28%). IBD and undetermined cause for bleeding were higher in the 10-18 years group (P = 0.026 and P = 0.017, respectively). Intestinal nodular lymphoid hyperplasia, foreign body ingestion, and esophageal varices were more common in the 0-4 years group (P = 0.034, P < 0.0001, and P = 0.029, respectively). Ten (4%) patients underwent one or more therapeutic interventions. The median follow-up period was two years (0.5-3). No mortality was reported in this study. GIB in children is an alarming condition, whose significance is increasing. LGIB, commonly due to IBD, was more common than UGIB, commonly due to gastritis.

Creating safe environments: optimal acoustic alarming of laypeople in fire prevention

Hazards like fires occur regularly and can cost people’s lives. Optimal auditory alarm signals enable laypeople to recognise dangers and to protect themselves. Existing fire alarm sound research focuses on alarm sounds and voice alerts presented singularly. We explored a combination of both and aimed to identify alarm signals that work optimally in everyday life. Thus, we conducted two online experiments: In Study 1 (N = 379), we tested eight alarm sounds regarding their typicality, their familiarity, their arousal, their valence, and their dominance. Siren-like alarm sounds were the most effective. In Study 2 (N = 206), we combined the four most effective alarm sounds with a voice alert. The voice alert reinforced ambiguity reduction, action motivation, and action intention. Hence, we suggest using alarm sounds with siren-like patterns. They should be combined with a voice alert to foster a quick and specific (target task-oriented) reaction. Practitioner summary: Warning laypeople is of great importance in time-critical hazards. In two remote testing studies (N Total = 585), auditory alarm sounds with siren-like patterns resulted in the most distinct and emotional perception. Combining the alarm sound with a voice alert adds meaning to the alarm and fosters action intention.

Anti-predator strategies of adult male Central Himalayan Langurs (Semnopithecus schistaceus) in response to domestic dogs in a human-dominated landscape.

The evolution of predator-prey relationships is an important topic in primatology. Many aspects of primate society have been explained as a response to predation pressure. While predation has been discussed in broad theoretical terms, few systematically collected data exist on the subject. Furthermore, little information exists regarding the inter-male variation in responses to predators. To address this data gap, predatory dog-primate interactions were studied in a 78-member group of habituated, individually recognized Central Himalayan Langurs (CHL) (Semnopithecus schistaceus) living in a high-altitude subsistence agricultural landscape of northern India. We recorded 312 langur-dog interactions over 2 years. These predation events resulted in 15 serious attacks on adult females, infants, juveniles and sub-adults, in eight of which the prey was killed and consumed on the spot. In response to dog predation, adult males performed three types of anti-predator response behaviors: direct fighting with a predator, emitting alarm calls, fleeing and/or freezing. Differences were noted in each male's response to village dogs. The results showed that the likelihood of CHL adult males engaging in more costly counterattacks or attention getting alarm calls were better predicted by the level of investment in the group (genetic relatedness, duration of residency, social relationships), but not rank and mating rate. Long-duration resident adult males performed high and/or intermediate cost behaviors to protect vulnerable members of the group; their potential offspring, maternal siblings or cousins, and adult female social partners. Short-term residents or recent immigrant males exhibited two less energetically costly, more self-preserving behaviors, depending on their rank: (1) high-ranking short-tenure duration males, with high mating frequencies, performed flee and freeze responses; (2) low-ranking, low-mating-frequency males performed more alarm calls. Counterattacks and alarm calls were performed by adult males with relatively more experience with village dogs and were directed towards dogs with predatory histories significantly more often than dogs with non-predatory histories. Natural selection and kin selection have both contributed to the evolution of CHL anti-predator tactics.

Recruitment Microcirculatory - Mitochondrial through a permissive systemic perfusion pressure combats microcirculatory - mitochondrial distress syndrome. Cases report

Systemic Perfusion Pressure, SPP disorders cause ischemia of the affected microcirculation with critical mitochondrial damage, manifested by a hypercarbia pCO2 AV &gt; 6 mm Hg. Thus, pCO2 has become an alarm signal, used as a marker of ischemia in terminal states with the generation of microcirculatory-mitochondrial distress syndrome, MMDS, and the installation of multiorgan organs dysfunction syndrome, MODS. Definition of SPP (~ 70 mm Hg), there is a difference between mean arterial pressure, MAP (90 mm Hg), and capillary resistance pressure, CRP (20 mm Hg) [1]. According to Maria Vasilieva's study [2,3], a tear can be a diagnostic test for various diseases. CRP in the practice of the doctor on duty can be compared with intraocular pressure, by the Kalmakov method, except for oculist glaucoma, consultation of which is essential for examining the fundus in these patients. Permissive optimization of perfusion pressure through Microcirculatory - Mitochondrial recruitment, MMR reduces the AV gap &lt; 6 mm Hg, thus reducing MMDS. Mitochondria promote energy homeostasis by improving the functions of biosystems and pauses the expansion of MODS. Maintaining permissive SPP in critically terminal states in daily emergency clinical practice contributed to their survival [1-5]. Thus, the decisive success of Multi-organ Supportive Therapy (MOST) in Extracorporeal Life Support Organizations (ELSO) has perfusion pressure.

Alarm Calling in Plateau Pika (Ochotona curzoniae): Evidence from Field Observations and Simulated Predator and Playback Experiments

Acoustic communication plays a vital role in passing or sharing information between individuals. Identifying the biological meaning of vocal signals is crucial in understanding the survival strategies of animals. However, there are many challenges in identifying the true meaning of such signals. The plateau pika (Ochotona curzoniae) is a call-producing mammal endemic to the Qinghai-Tibet plateau (QTP) and considered a keystone species owing to its multiple benefits in alpine rangeland ecosystems. Previous studies have shown that plateau pikas emit alarm calls as part of their daily activities. However, only field observations have been used to identify these alarm calls of the plateau pika, with no attempts at using playback experiments. Here, we report the alarm calling of plateau pikas through field observations as well as simulated predator and playback experiments in the Eastern QTP from 2021 to 2022. We found that both female and male adults emitted alarm calls, the signals of which comprised only one syllable, with a duration of 0.1-0.3 s. There were no differences in the characteristics between the observed alarm calls and those made in response to the simulated predator. The duration of the alarm call response varied with altitude, with plateau pikas living at higher altitudes responding at shorter durations than those at lower altitudes.

THE ANALYSIS OF THE PERCEPTION AND AWARENESS OF USM STUDENTS TOWARDS DOMESTIC VIOLENCE AGAINST FEMALES

Due to lockdowns and stay-at-home measures in combating COVID-19 worlwide, the number of domestic violence cases have increased tremendously since 2020. In order to eliminate domestic violence against females, it is imperative to better understand the background of domestic violence against females, as well as the societal institutions that promote its persistence. This study aimed at determining and analysing the perception and awareness level of USM students on domestic violence against females. The result showed that USM students have a strong awareness of different types of abuses. Among those six categories, 72.4% of the respondents strongly agreed with physical abuse as a form of domestic violence and had the largest mean 4.667 while 38.1% of respondents strongly agreed with stalking as a form of domestic violence with the lowest mean 3.905. However, the result also revealed that the majority of the students are unaware that the illness-based violence is one of the causes of domestic violence as opposed to the other five causes. We also found that there exists a significant difference of percentages of responses between strengthening laws and legislations against domestic violence as a potential solution (73.34%) with the mean of 4.686. This shows a rather alarming signal that USM students are generally too dependent on law and have the mindset that law can overcome domestic violence issues. Recommendations to improve the students’ awareness on this matter are presented accordingly.

Alarming signals: Worsening obesity, physical inactivity and high perception of stress in first-year medical and dental students in Chile

The high prevalence of obesity, smoking, and physical inactivity in Chile despite government-sponsored measures and campaigns, along with others in the last 30 years, suggests additional reinforcement of these efforts at the primary care level. To determine if lifestyles and modifiable health risk factors in first-year students from the University of Chile Faculties of Medicine and Dentistry, potential future promoters of healthy lifestyles, show changes throughout their first academic year. In a randomized stratified sample of 388 students according to sex and chosen career weight, height, waist circumference, waist circumference-weight ratio, food consumption, smoking prevalence and dependence, alcohol use, perceived stress level, and physical activity were measured at the first week, 3 and 6 months after their admission. The Cochrane test assessed dichotomic variables, and the Friedman test was used for nonparametric values. 253 students (186 women) completed the follow-up. A significant worsening of obesity (general and abdominal) and physical inactivity, persistent moderate and high-stress perception, and smoking prevalence were documented throughout the study period. The progressive obesity and physical inactivity, high-stress perception, and persistent smoking prevalence in the first year of academic life suggest considering measures in the curricular academic structure that facilitate adjustments in the student's lifestyles. Future follow-up of this cohort, increasing participants, and assessing students' mental health are planned.

Epidemiological Aspects and Antibiotics Susceptibility Patterns of Streptococcus pyogenes Isolated from Subjects with Tonsillitis, Sudan

Background: Globally, Streptococcus pharyngitis is a major public health challenge. The current study investigates the prevalence of Streptococcal pyogenes among children under 17 years old in ENT Kosti Teaching Hospital and examines the susceptibility of isolated S. pyogenes strains to commonly used antibiotics.Methods: A total of 384 throat swabs were obtained from children under the age of 17 who attended the Kosti Teaching Hospital between 2019 and 2021. Streptococcus pyogenes was isolated by conventional microbiology procedures. Each S. pyogenes strain was subjected to antibiotic susceptibility testing according to the CLSI guidelines.Results: Most participants of this study were females 219 (57%) and aged between 5 and 10 years 259 (67.4%). Out of the 384 participants, 134 (34.9%) and 255 (66.4%) suffered from lymphadenopathy and tonsil hyperplasia, respectively. Interestingly, lymphadenopathy and tonsil hyperplasia were more (P 0.05) in the 5–10 age group than those aged 11–16 years. Moreover, 41.4% of the participants were infected by a GAS sore throat. GAS sore throat is significantly associated with lymphadenopathy (AOR: 2.375, 95% CI: 1.479–3.815, P 0.000) and tonsil hyperplasia (AOR: 3.374, 95% CI: 1.939–5.874, P 0.000). Notably, males (AOR: 0.853, 95% CI: 0.549–1.325, P 0.479) and individuals aged 5–10 years (AOR: 0.867, 95% CI: 0.464–1.618, P 0.654) were less likely to have a GAS sore throat. In our study, all isolated strains were sensitive to penicillin. Clindamycin, azithromycin, and erythromycin resistance were observed in 7 (4.4%), 44 (27.7%), and 47 (29.6%) isolates, respectively.Conclusion: The study displayed the current situation of GAS sore throat in the White Nile state. Penicillin was found to be the effective drug to cure S. tonsillitis but a high rate of resistance to macrolides was noticed which is an alarming sign.

Benign Late T Wave Inversion Post Coronary Artery Bypass Grafting: Case Report of Myocardial Reperfusion Sign Appearing Late on ECG

The onset of new T wave inversion (TWI) on an electrocardiogram (ECG) has always been considered an alarming sign of myocardial ischemia. Successful myocardial infarction reperfusion is indicated by the presence of early TWI after revascularization. We report a case of benign late precordial TWI post-coronary artery bypass grafting (CABG) with no evidence of myocardial ischemia.

Migraine with aura and stroke - the role of warning signs in the context of secondary headaches: case report

IntroductionHeadache is a very common complaint in doctors' offices, with primary causes being the majority in relation to secondary ones. Despite this, the identification of secondary headaches is very relevant in clinical practice, since these can be a life-threatening condition, functionality or even a reversible cause. However, imaging screening for all individuals with headache is costly and unrewarding. Therefore, it is important to know the warning signs that, together with the clinical context, lead to a more precise indication of these exams and early and well-targeted therapeutic interventions.Clinical caseThis is a 60-year-old man, previously dyslipidemic and smoker, with migraine with aura reported since childhood, who underwent treatment with sodium valproate, with headache attack suppression. About 4 months before admission, he presented with an alteration in the pain pattern, amaurosis fugax in the right eye, dizziness and mild paresis and hypoesthesia in the left side of the body, primarily treated by him as migraine crises, without improvement with the use of triptans. A new outpatient investigation was carried out, which showed multiple small infarcts in the right hemisphere secondary to atheromatous plaque in the right carotid bulb with an obstruction of approximately 85%. Diagnostic and therapeutic arteriography was performed, with stent implantation, uneventfully.ConclusionThe differential diagnosis between migraine with aura and a cerebrovascular event has already been widely reported in the literature and constitutes a pitfall in the routine of headaches, since a serious and potentially disabling condition can be overlooked. The joint evaluation of the alarm signs with the global context becomes an important tool in the propaedeutics of these patients, with knowledge of this casuistry being something relevant within clinical practice.
