RESUMO

INTRODUCTION/AIMS: Electrodiagnostic examinations, such as nerve conduction studies (NCS) and needle electromyography (EMG), are perceived as painful by children and their parents/guardians. Methods to reduce peri-procedural pain improve compliance and have neurocognitive and neuropsychiatric benefits. This study aimed to assess the efficacy of combined oral and topical analgesics (COTA), oral analgesics (OA), and placebo in reducing pain during NCS/EMG in children. METHODS: We performed a double-blind, randomized, placebo-controlled trial on children presenting to our neurophysiology lab. Patients were stratified into two age groups (6M-6Y and 7Y-18Y) and randomized into three arms: COTA, OA, and placebo. Pain scores post-NCS/EMG were assessed using the Modified Behavioral Pain Scale (MBPS) and Faces Pain Scale-Revised (FPS-R). RESULTS: One hundred thirteen participants were enrolled. A comparison of participants from both age groups combined revealed no significant differences in guardian FPS-R scores across all arms for NCS and EMG. A significant difference in the distribution of post-NCS FPS-R score severities in children aged 7Y-18Y was noted between OA and placebo (p = .007). EMG was more painful than NCS across all arms (p < .05). In children aged 6M-6Y undergoing at least 10 muscle samplings during EMG, those receiving COTA had significantly lower pain scores (p = .014). DISCUSSION: This study reveals the complexity of pediatric pain perception during NCS/EMG and highlights that other methods to reduce experienced pain are required. Our findings suggest that procedural characteristics, such as number of muscles sampled, may influence the effectiveness of analgesia and serve as a foundation for future research aimed at optimizing pain management strategies.

RESUMO

BACKGROUND: Ischemic stroke associated with coronavirus 2019 (COVID-19) has been well recognized by now. Few studies have compared COVID related versus unrelated strokes. We intend to report on a large group of Asian patients from two countries and compare COVID with non-COVID strokes admitted during the same time period. METHODS: Consecutive cases of acute ischemic stroke either presenting or developing, between March 2020 and December 2021 in four tertiary care hospitals (1 in Dubai, UAE and 3 in Karachi, Pakistan) and testing positive for COVID-19 were included in the study. Patients admitted with ischemic stroke during the same time period and who tested negative for COVID-19 were also randomly selected from the four hospitals. All data was collected from the medical records of the patients and recorded on a standard questionnaire before it was entered in SPSS version 21 for analysis. RESULTS: There were 139 COVID positive and 271 COVID negative patients with acute ischemic stroke included in the current study. There were significantly more males (80.6% vs 64.9%, p=0.001) and more large vessel strokes in the COVID positive group (41% vs 21.8%, p<0.001). Being COVID positive was an independent predictor of poor outcome at discharge, defined as a modified Rankin score of 3-6 (OR 3.87, 95% CI 2.21-6.77) after adjusting for country, age, sex, vascular comorbid conditions and stroke subtype. CONCLUSIONS: In this largest series of patients with COVID related strokes from Asia, COVID-19 was an independent predictor of poor outcomes at discharge after adjusting for other variables.

RESUMO

Cerebral venous thrombosis (CVT) is an uncommon cerebrovascular disease, which has been reported with covid infection as well as covid vaccines, particularly AstraZeneca and Janssen vaccines. We present four consecutive cases of CVT after receiving either Sinopharm or Sinovac vaccine, both of which are composed of an inactivated-virus. All the patients recovered well with anticoagulation and discharged with a good functional outcome. This is the first case series reporting CVT following the administration of these vaccines.

RESUMO

OBJECTIVES: Amongst all the global catastrophe due to Coronavirus disease 2019, a significant bright spot is a reduction in air pollution as countries undergo lockdowns to limit the spread of infection. Another reduction that has been reported is in the number of strokes presenting to hospitals, despite the virus implicated in causing a hypercoagulable state. Acute exposure to air pollution has been linked to increase in stroke incidence and the improvement in air quality may be responsible for the decrease in stroke presentations. MATERIALS AND METHODS: To explore this hypothesis, we compared the air quality index (AQI) of Karachi, the largest cosmopolitan city of Pakistan, during the lockdown period in 2020 to the same period in the previous year. RESULTS: We found a significant drop in AQI depicting an improvement in air quality. Simultaneously, we identified a drop in number of stroke admissions to less than half from 2019 to 2020 at one of the largest tertiary care hospitals of the city, during this period of interest. CONCLUSION: We hypothesize that one important reason for this drop in stroke admissions, may be an actual reduction in stroke incidence brought about by an improvement in air quality.

RESUMO

The aim of the present study was to determine the deleterious effects of prolonged oral cyanide insult on various organs and tissues in rabbits. For this purpose, 12 locally bred adult male rabbits were allocated into two groups of 6 viz. control and experimental. Rabbits in control group were offered feed only while the rabbits in experimental group received feed plus potassium cyanide (KCN) at 3 mg/kg body weight orally for a period of 40 days. None of the rabbit in both the groups demonstrated any of the gross changes in any organ on postmortem examination. Liver was normal in size, shape, texture and color. Kidneys were also normal in size and color. Histopathological examination revealed severe hepatocyte vacuolation and degeneration in liver of rabbits in experimental group. There was also excessive congestion in liver and bile duct of rabbits in experimental group. Kidneys of rabbits in experimental group demonstrated severe glomerular and tubular necrosis and congestion. In the tubular epithelial cells, pyknotic nuclei were also present. On the other hand, heart and pancreas of rabbits in both control and experimental group did not show any histopathological change in microscopic structures. In conclusion, prolonged oral cyanide administration could have harmful effects on liver and kidney functions.

RESUMO

Coccidiosis is a protozoal and occasionally fatal diarrheic disease of goats imposing heavy economic losses to farming community. This study aimed to evaluate the efficacies of Furazolidone, Sulfadimidine and Amprolium against coccidiosis in Beetal goats. Twenty-four (24) Beetal goats naturally infected with coccidiosis were randomly divided into four groups of 6 (A-D). Goats in groups A, B and C were treated orally with Furazolidone (10 mg/Kg), Sulfadimidine (100 mg/Kg) and Amprolium (55 mg/Kg), respectively for 7 days. Goats in-group D served as positive control. Oocysts per gram (OPG) of feces counts of individual goats in each group were performed on Days; 0 (pre-treatment) 7, 14 and 21 (post-treatment). OPG counts amongst goats in all groups at day 0 were not significant (P>0.05). On days 7, 14 and 21, OPG values decreased significantly (P<0.05) in groups A, B and C compared to group D. The efficacy of Furazolidone, Sulfadimidine and Amprolium was 98.6, 98.0 and 99.6 percent, respectively on Day 21 (end of trial). Statistically, the efficacies of three drugs were not significantly different (P>0.05). In conclusion, Furazolidone, Sulfadimidine and Amprolium are well-tolerated and any one of these may be recommended to effectively treat coccidiosis in Beetal goats.

RESUMO

Twelve adult rabbits bred locally were divided into two equal groups of 6; experimental and control groups. Rabbits in the experimental group were orally dosed with KCN at 3mg/kg body weight for 40 consecutive days. Members in control group were given placebo (distilled water) for the same period. Animals in both groups were offered feed at 90gm/kg/day while ample drinking water was available ad lib. Feed consumption and body weight of rabbits in both the groups were recorded. Blood samples were also drawn to determine various hematological parameters. Statistical analysis revealed a non-significant difference of total and daily feed intakes in rabbits of experimental and control groups. Whereas the feed efficiency of rabbits in the experimental group were significantly reduced (P<0.05) compared to controls. Likewise a significant decrease in body weight gain of rabbits in experimental group (P<0.05) was observed. A non-significant difference (P>0.05) was observed in leukocyte count, differential leukocyte count and platelets of rabbits in both the groups. Erythrocyte count, hemoglobin concentration, packed cell volume and mean corpuscular hemoglobin were significantly decreased in treated rabbits. It was concluded that chronic cyanide intake had a deleterious effect on feed efficiency, growth rate and blood components of rabbits.

RESUMO

This review focuses on emerging risk factors for stroke, including air pollution and climate change, gut microbiota, high altitude, and systemic infection. Up to 14% of all stroke-associated mortality is attributed to air pollution and is more pronounced in developing countries. Fine particulate matter and other air pollutants contribute to an increased stroke risk, and this risk appears to increase with higher levels and duration of exposure. Short term air pollution exposure has also been reported to increase the stroke risk. The gut microbiota is a complex ecosystem of bacteria and other microorganisms that reside in the digestive system and affect multiple body systems. Disruptions in the gut microbiota may contribute to stroke development, possibly by promoting inflammation and atherosclerosis. High altitudes have been associated with erythrocytosis and cerebrovascular sinus thrombosis, but several studies have reported an increased risk of thrombosis and ischemic stroke at high altitudes, typically above 3000 m. Systemic infection, particularly infections caused by viruses and bacteria, can also increase the risk of stroke. The risk seems to be greatest in the days to weeks following the infection, and the pathophysiology is complex. All these emerging risk factors are modifiable, and interventions to address them could potentially reduce stroke incidence.

RESUMO

INTRODUCTION: Previous reports and meta-analyses derived from small case series reported a mortality rate of up to 40% in patients with coronavirus disease 2019 associated cerebral venous thrombosis (COVID-CVT). We assessed the clinical characteristics and outcomes in an international cohort of patients with COVID-CVT. PATIENTS AND METHODS: This was a registry study of consecutive COVID-CVT patients diagnosed between March 2020 and March 2023. Data collected by the International Cerebral Venous Thrombosis Consortium from patients with CVT diagnosed between 2017 and 2018 served as a comparison. Outcome analyses were adjusted for age and sex. RESULTS: We included 70 patients with COVID-CVT from 23 hospitals in 15 countries and 206 controls from 14 hospitals in 13 countries. The proportion of women was smaller in the COVID-CVT group (50% vs 68%, p < 0.01). A higher proportion of COVID-CVT patients presented with altered mental state (44% vs 25%, p < 0.01), the median thrombus load was higher in COVID-CVT patients (3 [IQR 2-4] vs 2 [1-3], p < 0.01) and the length of hospital stay was longer compared to controls (11 days [IQR 7-20] vs 8 [4-15], p = 0.02). In-hospital mortality did not differ (5/67 [7%, 95% CI 3-16] vs 7/206 [3%, 2-7], aOR 2.6 [95% CI 0.7-9]), nor did the frequency of functional independence after 6 months (modified Rankin Scale 0-2; 45/58 [78%, 95% CI 65-86] vs 161/185 [87%, 81-91], aOR 0.5 [95% CI 0.2-1.02]). CONCLUSION: In contrast to previous studies, the in-hospital mortality rate and functional outcomes during follow-up did not differ between COVID-CVT patients and the pre-COVID-19 controls.

RESUMO

INTRODUCTION AND OBJECTIVE: Safe care is a challenge around the globe, especially in developing countries. In resource-limited settings achieving patient safety is an additional complexity. Patient safety is now considered a significant public health concern worldwide. Despite a vital role in delivering quality care, little attention has been given to describe healthcare professionals' perceptions of the patient safety culture in Pakistan. This study aimed to assess the patient safety culture at a tertiary care public hospital in Lahore from the perspectives of doctors and nurses. METHODS: During this cross-sectional study, data were collected from 290 nurses and doctors using a validated safety assessment survey tool of the Hospital Survey of Patient Safety Culture (HSOPSC). The respondent's demographic characteristics and study variables influencing patient safety culture were presented, and a chi-square test was applied to identify the variables influencing patient safety. RESULTS: A total of 114 medical doctors (39.3%) and 176 registered nurses (60.7%) participated in assessing patient safety culture (PSC) across tertiary care public healthcare centers in Lahore. The dimensions of organizational learning and continuous improvement (90.6%) and teamwork within units (86.6%) were the highest. Other dimensions include feedback and communication about the error (71.8%), teamwork across units (74.9%), management support for patient safety (67.3%), supervisor/manager expectations, and actions promoting patient safety (64.6%), communication openness (64.5%), overall perceptions of patient safety (65.3%), frequency of events reported (58.7%), and handoffs and transitions (60.9%) showed moderate status. The dimensions of staffing (35.8%) and non-punitive response to errors (39.1%) had the lowest score. CONCLUSIONS: The present public hospital survey results revealed that medical staff working in a healthcare setting have a less positive perception of patient safety culture.

RESUMO

BACKGROUND/OBJECTIVE: Cerebral venous thrombosis (CVT) has been increasingly reported in patients with COVID-19. Most published literature is descriptive and focuses only on CVT in COVID-19 patients. The objective of our study was to compare CVT patients' characteristics with and without an associated COVID-19 infection. MATERIALS AND METHODS: This is a retrospective cross-sectional study. All adult patients with a confirmed diagnosis of CVT admitted to our hospital over a period of 30 months, from January 2019 to June 2021, were included. They were further divided into two groups, with and without COVID-19 infection. RESULTS: A total of 115 CVT patients were included, 93 in non-COVID-CVT and 22 in COVID-CVT group. COVID-CVT patients were male predominant and of older age, with longer hospital stay, and higher inpatient mortality. COVID-CVT patients presented with a higher frequency of headache (82% vs. 63%), seizures (64% vs. 37%, p = 0.03), hemiparesis (41% vs. 24%), and visual changes (36% vs. 19%) as compared to non-COVID-CVT patients. Venogram showed a higher frequency of superior sagittal sinus (64% vs. 42%) and internal jugular vein (23% vs. 12%) involvement in the COVID-CVT cohort. More than 90% of patients in both groups received therapeutic anticoagulation. Mortality rates were higher in COVID-CVT group (18% vs. 11%). CONCLUSION: COVID-CVT patients were male predominant and of older age, with higher hospital stay, and higher inpatient mortality as compared to non-COVID-CVT patients.

RESUMO

In human medical practice, a hematological rule of three has been validated for healthy human populations. One such formula is estimating hemoglobin (Hb) levels as 1/3rd of Packed Cell Volume (PCV). However, no such hematological formulae have been devised and validated for veterinary medical practice. The present study was devised with an aim to evaluate the relationship between hemoglobin (Hb) concentration and Packed Cell Volume (PCV) in camels (n = 215) being reared under pastoralism, and to devise a simple pen-side hematological formula for estimation of Hb from PCV. The PCV was determined through microhematocrit method whereas Hb estimation by cyanmethaemoglobin method (HbD). The Hb was also calculated as 1/3rd of PCV and was dubbed as calculated Hb (HbC). Overall HbD and HbC were significantly (P≥0.05) different. Similar results were attained for all study groups i.e. males (n = 94) and females (n = 121), and young (n = 85) and adult (n = 130) camels. The corrected Hb (CHb) was deduced through regression prediction equation attained from linear regression model. Scatterplots were drawn, linear regression was carried out, and Bland Altman chart was built for agreement of both methods of Hb estimation. A non-significant (P≥0.05) difference was noticed between HbD and CHb. Bland Altman agreement analysis revealed satisfactory agreement between HbD and CHb and the data was distributed closely around the mean difference line (Mean = 0.1436, 95% CI = 3.00, -2.72). A simplified pen-side hematological formula for deducing Hb concentration from PCV is accordingly recommended viz. Hb concentration (g/dL) = 0.18(PCV)+5.4 for all age and gender groups of camels instead of its calculation as one-third of PCV.

RESUMO

BACKGROUND/OBJECTIVE: The aim of this study is to identify frequencies of various neurological disorders (NDs) and associated disability in patients attending neurologic clinics in rural and urban centers in Pakistan. METHODS: This is an observational study conducted in 39 neurological centers in both rural and urban areas, public and private health sectors all over Pakistan. This study was conducted between august 2017 to December 2019. RESULTS: A total of 28,845 adults were enrolled. Mean age of the study participants was 46.2 ± 17.2 years, 15,252 (52.9%) were men and 13,593 (47.1%) were women. Most common comorbid medical condition was hypertension 7622(26.4%) followed by Diabetes 3409(11.8%). Among neurological diagnoses, vascular diseases (20%) were the most common followed by Headache disorders (18.6%), Epilepsy (12.5%), nerve and root diseases (12.4%), Psychiatric diseases (10%), Dementias (8%) and movement disorders (7.9%). Half of the patients 15,503(53.7%) had no neurological disability, while minor disability was present in 10,442(36.2%) of cases. Moderate to severe disability was present in 2876(10%) cases. Headache disorders, psychiatric diseases, muscle pain/muscle related disorders and demyelinating diseases were more common in women. Vascular diseases, movement disorders and Dementias were more common in 46 years and above age group whereas headache disorders, Epilepsy and Psychiatric disorders were more prevalent in <46 years age groups. CONCLUSION: Vascular diseases are the most common presentation of patients in neurology clinics followed by headache disorders and epilepsies. Minor disability was present in 36% while moderate to severe disability was present in 10% cases.

RESUMO

Background: Vaccine apprehension poses a serious threat to global health. While there has been a tremendous global effort to create a vaccine against coronavirus disease 2019 (COVID-19), little is known about its reception in  Iraq. Therefore, we sought to examine COVID-19 vaccine acceptance, hesitation, and related elements in the Iraqi population. Methods: Between the 19th of May and the 22nd of September 2021, a descriptive, cross-sectional web-based survey was conducted employing a quantitative approach. Respondents from both sexes aged 18 years and above who live in Iraq and agreed to participate were included. An anonymized online structured questionnaire was designed based on data from prior research on vaccine  hesitation in general,  and COVID-19 vaccination reluctance specifically. Results: A total of 1221 eligible participants from various regions in Iraq actively participated in the short web-based questionnaire. The overall acceptance rate of the COVID-19 vaccine was 56.2%, with a greater acceptance rate among younger male participants (p<0.05). Marital status had no significant association (p=0.834). Urbanization influenced the acceptance rate significantly (p=0.002). The barriers to receiving the COVID-19 vaccine were exemplified by the vaccine not being evaluated for a sufficient period in 51.4% of the responses, as well as concerns about future side effects in 76.6% of the responses and a lack of efficacy in 55.7% of the responses. The Pfizer-BioNTech vaccine received 39.6% preference and participants confidence, followed by the Oxford/AstraZeneca vaccine at 18.1% and the Sinopharm vaccine at 14.6%. Conclusions: COVID-19 vaccination apprehension was discovered in almost half of the study population. Lack of understanding about vaccination eligibility, anxiety about adverse events and vaccine efficacy, and distrust in the government were independently predictive of vaccine hesitation.

RESUMO

PURPOSE: Neurologic involvement is commonly reported in coronavirus disease (COVID-19) patients. The published literature regarding the COVID-19-related neurophysiological findings, including the EEG findings, is still quite limited. The objective of this study was to evaluate the EEG findings in patients with a COVID-19 infection and look for a possible correlations and prognosis. METHODS: This is an inpatient hospital-based retrospective observational study. All admitted COVID-19 patients undergoing an EEG study between January 1, 2020 and June 30, 2021 were included in this study. EEG was ordered by the primary intensive care physician or a neurologist taking part in the clinical care of patients. RESULTS: Sixty-six EEG studies in 57 patients were included. Mean age was 62.2 ± 16.3 years with male predominance (65%). Encephalopathy (70%) was the most common indication for an EEG. Background EEG abnormalities were seen in most of the patients (92.4%) with severe abnormalities correlating with the prognosis of the patient. Epileptiform discharges were only seen in 7.5% of the EEGs, with majority of the discharges arising from the frontal region. Mortality reported was high (47%). CONCLUSIONS: Nonspecific diffuse background EEG abnormalities are commonly seen in COVID-19 patients. Epileptiform discharges are less common but mostly originate from frontal region. Most of these patients also had an abnormal neuroimaging. The significance of this peculiar finding needs further research. SIGNIFICANCE: Nonspecific background EEG changes are common in COVID-19 patients. Among epileptiform discharges, focal epileptiform discharges arising from the frontal region were common, usually associated with an abnormal neuroimaging.

RESUMO

The current study highlights prospective mechanisms of biogenesis of extracellular vesicles (EVs) and potential involvement in cellular signaling and transport with great emphasis to illustrate their role as biomarkers in certain pathologies. The current review highlights EVs, the heterogeneous entities secreted by cells in highly conserved manner. A series of consensus terminologies for various types is yet to be organized. Exosomes, microvesicles and apoptotic bodies are major populations among EVs. EVs are key regulators in cellular physiological homeostasis, disease progression and evolve either from plasma membrane (microvesicles) or fusion of endosomes with exosomes. However, how vesicular inclusions elicit a plethora of biological responses is still not much clear. However, how these vesicular inclusions get packaged and delivered by these EVs shows great involvement in inter- and intracellular cellular signaling and channeling of multiple proteins, variety of RNAs and certain fat molecules. It's worth to mention that EVs carry small non-coding RNAs (snRNAs) which are involved in multiple cellular molecular events at targeted sites. Moreover, snRNA trafficking through exosomes and microvesicles depicts remarkable potential as non-invasive biomarkers in different clinical disorders especially immune system pathologies, cardiovascular issues, and metabolic syndromes.

RESUMO

OBJECTIVE: Neurological manifestations in patients with coronavirus disease 2019 (COVID-19) have been reported from early features of anosmia and dysgeusia to widespread involvement of the central nervous system, peripheral nervous system, as well as the neuromuscular junction and muscle. Our study objective is to evaluate the electromyography and nerve conduction study (EMG/NCS) findings among COVID-19 patients and look for possible correlations. METHODS: This is a hospital-based retrospective observational study. All COVID-19 patients between the period of 1st January 2020 to 31st December 2020 undergoing an EMG/NCS were included. RESULTS: Eighteen patients (12 male and 6 female) were included. Mean age was 55 ± 12 years. 11 patients required intubation for a mean period of 18.6 days (range: 3-37 days). Electrodiagnostic findings were consistent with a myopathy in a majority of these patients (82%). Five of them also had a concurrent axonal neuropathy. In the remaining patients who did not require intubation (n = 7), three patients had myopathic EMG changes and one had Guillain Barre syndrome. CONCLUSION: At this time, there are no neuromuscular-specific recommendations for patients who contract COVID-19. Only time and additional data will unveil the varying nature and potential neurological sequelae of COVID-19. SIGNIFICANCE: Myopathic EMG changes are commonly seen in critically ill COVID-19 patients, especially with a prolonged hospital stay.

RESUMO

BACKGROUND AND PURPOSE: Coronavirus disease 2019 (CO-VID-19) has an increased propensity for systemic hypercoagulability and thromboembolism. An association with cerebrovascular diseases, especially cerebral venous thrombosis (CVT), has been reported among these patients. The objective of the present study was to identify risk factors for CVT as well as its presentation and outcome in COVID-19 patients. METHODS: This is a multicenter and multinational observational study. Ten centers in 4 countries (Pakistan, Egypt, Singapore, and the United Arab Emirates) participated in this study. The study included patients (aged >18 years) with symptomatic CVT and recent COVID-19 infection. RESULTS: Twenty patients (70% men) were included. Their mean age was 42.4 years, with a male-to-female ratio of 2.3:1. Headache (85%) and seizures (65%) were the common presenting symptoms, with a mean admission Glasgow Coma Scale (GCS) score of 13. CVT was the presenting feature in 13 cases (65%), while 7 patients (35%) developed CVT while being treated for COVID-19 infection. Respiratory symptoms were absent in 45% of the patients. The most common imaging finding was infarction (65%), followed by hemorrhage (20%). The superior sagittal sinus (65%) was the most common site of thrombosis. Acute inflammatory markers were raised, including elevated serum D-dimer (87.5%), erythrocyte sedimentation rate (69%), and C-reactive protein (47%) levels. Homocysteine was elevated in half of the tested cases. The mortality rate was 20% (4 patients). A good functional outcome was seen in the surviving patients, with a mean modified Rankin Scale score at discharge of 1.3. Nine patients (45%) had a modified Rankin Scale score of 0-1 at discharge. CONCLUSION: COVID-19-related CVT is more common among males at older ages when compared to previously reported non-COVID-19-related CVT cases. CVT should be suspected in COVID-19 patients presenting with headache or seizures. Mortality is high, but functional neurological outcome is good among survivors.

RESUMO

Cerebellar ataxia has a very broad differential diagnosis in adults, including paraneoplastic and postinfectious etiologies. We report a case of a 56-year-old male presented with right-sided cerebellar dysfunction preceded by fever and headache. He was diagnosed with subacute postinfectious cerebellar ataxia. Blood serology showed the presence of anti-amphiphysin and anti-Ri (ANNA-2, antineuronal nuclear autoantibody type 2) antibodies, which have a known association with cerebellar syndrome. The patient subsequently improved with the steroids. Although no evidence of an underlying tumor was found in the patient, the presence of the paraneoplastic antibodies remains a mystery. We suggest a probable association of these antibodies with the postinfectious cerebellar syndrome.

RESUMO

Antidepressant discontinuation syndrome (ADDS) is reported to occur in almost 30-50% of the patients who take antidepressants for a duration of at least four to six weeks and then suddenly discontinue the drug. Since there is an increase in the use of antidepressants for various reasons by general practitioners, patient education about when and how to discontinue a drug is not acknowledged enough. It is reported to occur with the use of different classes of antidepressants - selective serotonin reuptake inhibitor (SSRI), monoamineoxidase inhibitor (MAOI), tricyclic antidepressants (TCAs), and atypical antipsychotics like risperidone, trazodone, clozapine, and venlafaxine. Slow tapering off the drugs has also caused ADDS. Symptoms start within two to four days of quitting the drug and are usually mild lasting for two to four weeks (can persist for six to 12 months) but could be severe enough leaving the patient nonambulatory. Here, we represent a case of a 55-year-old female who presented to the outpatient clinic with complaints of headache, vomiting, and diarrhea. The patient had 10 to 12 episodes of watery diarrhea every day and bilateral, continuous, pressing headache associated with multiple episodes of non-projectile vomiting. She was investigated for ultrasound sonography (USG) abdomen, CT head, and lab investigations which turned around to be normal. A follow-up visit with detailed history revealed she suddenly stopped taking escitalopram after six months by herself without tapering off the dose, two days before the onset of symptoms. Escitalopram was reinstated and the symptoms started to resolve in two to three days. All the unnecessary investigations and treatment could have been prevented if the proper history was taken and revealed at the initial visit.
