Diplopia from Subacute Bilateral Subdural Hematoma after Spinal Anesthesia

Subdural hematoma (SDH) is a rare, but life-threatening complication of spinal anesthesia. Subdural hematoma resulting from this procedure could present with vague symptoms such as chronic headache and could easily be missed. Chronic headache is one of the symptoms of chronic SDH in postpartum women. Diplopia as the presenting complaint in SDH secondary to peripartum spinal anesthesia has not, to our knowledge, been previously reported. Here, we report a case of diplopia secondary to postpartum subacute bilateral SDHs with transtentorial herniation after spinal anesthesia in a healthy primagravid 25-year-old woman. SDH can expand gradually and the initial symptoms might be subtle as in our case, despite critically high intracranial pressure

Gigantic Stomach: A Rare Manifestation of Duchenne Muscular Dystrophy

Duchenne muscular dystrophy (DMD) is characterized by degeneration and atrophy of skeletal, cardiac, and smooth muscles after a latent period of apparently normal development and function. The gastrointestinal manifestations start in the second decade of life and are mainly due to atrophy of smooth muscle layers. Refractory gastroparesis and chronic constipation can lead to severe gastric and small bowel dilatation, which can be life threatening. Here, we present a case of a 21-year-old male with a gigantic stomach secondary to DMD resolved with conservative management and no surgical intervention

The Role of Acetyl Cysteine in Cocaethylene (Non-Acetaminophen) Acute Liver Failure

Background: Acute liver failure can result from acetaminophen overdose, viral infection, toxins, and other disease conditions. Liver transplant is available in limited fashion and the criteria are strict as to who should get an available liver. N- Acetyl Cysteine (NAC) has been used in non-acetaminophen induced liver failure with success. Here we report a case of acute liver failure from cocaethylene that was reversed with NAC along with other medical therapy. Case Presentation: A 50-year-old female patient presented to the Emergency Department (ED) with a two-day history of coffee ground vomiting and hematemesis. She reported occasional substance abuse and heavy alcoholism. She reported shortness of breath and chest pain from the recurrent forceful vomiting. The rest of the review of systems was unremarkable except a fall from intoxication. Physical examination revealed anicteric conjunctiva and nontender abdomen and her vital signs were within normal limits. Initial blood work revealed acute liver and renal failure. The patient was started with general medical management and liver transplant service rejected the case due to active substance abuse. She underwent brief hemodialysis and was started on NAC. Over the course of her hospital stay her liver function and kidney function improved significantly and patient was discharged to home. Conclusion: In cases where liver transplant is not an option for various reasons including active substance abuse, a trial of N-Acetyl Cysteine may be beneficial and should be considered in the Emergency Department

Epidemiology of stroke patients in Tikur Anbessa Specialized Hospital: Emphasizing clinical characteristics of Hemorrhagic Stroke Patients

Background: Stroke is one of the leading causes of death and adult disability. Unlike the developed world, hemorrhagic stroke has been reported to be more prevalent in sub-Saharan Africa. Risk factors and determinants of stroke are not well identified in Ethiopia.Methods: A retrospective chart review of all stroke patients who presented from December 2010 to December 2014 was conducted. Demographic characteristics, risk factors and stroke types and their hospital outcome were reviewed, emphasizing on hemorrhagic stroke patients.Result: During the study period, 301 patients were seen for stroke, of which a total of 139(46.1%) were hemorrhagic stroke patients. From the hemorrhagic stroke patients, 88 (63.3%) of them were male and 51 patients (36.7%) were female. From those hemorrhagic stroke patients, 103 patients (74.1%) of them had hypertension. Majority, 65(63.1%), of hypertensive hemorrhagic stroke patients were not adherent to their antihypertensive medication. From hemorrhagic stroke patients with HTN, 28(27%) of them were diagnosed to have HTN after stroke already occurred. From the study participants, 58(19.2%) of the patients died in the hospital and 35 (60.3%) of them were hemorrhagic stroke.Conclusion: The proportion of hemorrhagic stroke is higher compared with other developed countries. Untreated hypertension may be the contributing factor. Early detection of hypertension and strict control, early health seeking, and good comprehensive stroke care will potentially decrease the mortality and morbidity of stroke.Key words: Stroke, Hemorrhagic, Hypertension, non-complianc

Effects of Novel Calpain Inhibitors in Transgenic Animal Model of Parkinson\u27s Disease/Dementia with Lewy Bodies

Parkinson\u27s disease (PD) and dementia with Lewy bodies (DLB) are neurodegenerative disorders of the aging population characterized by the accumulation of alpha-synuclein (alpha-syn). The mechanisms triggering alpha-syn toxicity are not completely understood, however, c-terminus truncation of alpha-syn by proteases such as calpain may have a role. Therefore, inhibition of calpain may be of value. The main objective of this study was to evaluate the effects of systemically administered novel low molecular weight calpain inhibitors on alpha-syn pathology in a transgenic mouse model. For this purpose, non-tg and alpha-syn tg mice received the calpain inhibitors - Gabadur, Neurodur or a vehicle, twice a day for 30 days. Immunocytochemical analysis showed a 60% reduction in alpha-syn deposition using Gabadur and a 40% reduction using Neurodur with a concomitant reduction in c-terminus alpha-syn and improvements in neurodegeneration. Western blot analysis showed a 77% decrease in alpha-spectrin breakdown products (SBDPs) SBDPs with Gabadur and 63% reduction using Neurodur. There was a 65% reduction in the active calpain form with Gabadur and a 45% reduction with Neurodur. Moreover, treatment with calpain inhibitors improved activity performance of the alpha-syn tg mice. Taken together, this study suggests that calpain inhibition might be considered in the treatment of synucleinopathies

Prospective Assessment of Patients with Stroke in Tikur Anbessa Specialised Hospital, Addis Ababa, Ethiopia

Introduction: The burden of stroke is increasing in many low- and middle-income countries. In Ethiopia, stroke has become a major cause of morbidity, long-term disability, and mortality. Time from stroke onset to hospital presentation is a critical factor in acute stroke care. This study aimed to describe risk factors for stroke and clinical presentation of patients presenting to the emergency centre with stroke. Methods: We conducted a cross sectional study conducted from August 2015 to January 2016 in an urban tertiary care centre in Addis Ababa, Ethiopia. Descriptive statistics and multivariable logistic regression models were used to evaluate associations between stroke types and stroke risk factors, and delayed presentation and clinical indicators. P-values less than .05 were considered statistically significant. Results: A total of 104 patients were included. The mean age was 53years, and 56% were male. Only 30% of patients arrived using an ambulance service. The most common presenting symptoms were altered mental status (48%), hemiparesis (47%), facial palsy (45%), hemiplegia (29%), and aphasia (25%). Hypertension was the most common risk factor (49%), followed by cardiovascular disease (20.2%) and diabetes mellitus (11%). The majority of strokes were haemorrhagic in aetiology (56%). The median arrival time to the emergency centre was 24h after symptoms onset; only 15% presented within three hours. Patients with hypertension, or presented with loss of consciousness were significantly more likely to have haemorrhagic stroke (\u3c .001 and p=.01 respectively). The only risk factor robustly associated with ischaemic stroke was cardiac illness (odds ratio 3.99, p=.01). Discussion: Our study identified hypertension to be the most common risk factor for stroke. The predominant aetiology type in this cohort is haemorrhagic stroke. Lastly, the median arrival time to an emergency centre was 24h after symptom onset

Development and Utilization of 3D Printed Material for Thoracotomy Simulation

Medical simulation is a widely used training modality that is particularly useful for procedures that are technically difficult or rare. The use of simulations for educational purposes has increased dramatically over the years, with most emergency medicine (EM) programs primarily using mannequin-based simulations to teach medical students and residents. As an alternative to using mannequin, we built a 3D printed models for practicing invasive procedures. Repeated simulations may help further increase comfort levels in performing an emergency department (ED) thoracotomy in particular, and perhaps this can be extrapolated to all invasive procedures. Using this model, a simulation training conducted with EM residents at an inner city teaching hospital showed improved confidence. A total of 21 residents participated in each of the three surveys [(1) initially, (2) after watching the educational video, and (3) after participating in the simulation]. Their comfort levels increased from baseline after watching the educational video (9.5%). The comfort level further improved from baseline after performing the hands on simulation (71.4%)

B-Type Natriuretic Peptide: A Predictor for Mortality, Intensive Care Unit Length of Stay, and Hospital Length of Stay in Patients With Resolving Sepsis

Background: B-type natriuretic peptide (BNP) is a hormone secreted by cardiomyocytes in response to myocardial ischemia, increased ventricular wall tension, and overload. BNP is utilized as a diagnostic and prognostic marker in congested heart failure (CHF). Its prognostic value in sepsis is unknown. The aim of this study is to determine if BNP correlates with increased in-hospital mortality for septic patients. Methods: This was a retrospective study of 505 patients admitted for sepsis or severe sepsis or septic shock during the period of January 2013 and August 2014. Patients that received \u3e 3 L of intravenous fluids on presentation were included. Intensive care unit length of stay (ICULOS), hospital length of stay (HLOS) and in-hospital mortality were measured. Mean BNP level was calculated and compared to ICULOS and HLOS and in-hospital mortality. Controlled variables included ejection fraction (measured by echocardiogram within 6 months of presentation), glomerular filtration rate (calculated by Cockroft-Gault equation), patient demographics, and lactic acid trends. Exclusion criteria were no echocardiogram within 6 months of admission, no BNP levels on admission, and no repeat lactate or rising lactate levels within 24 h to indicate worsening sepsis. Results: Patients\u27 mean BNP with in-hospital mortality was 908 pg/mL as compared to mean BNP of 678 pg/mL in survivors. T-test comparisons were statistically significant (P = 0.0375). The Kaplan-Meier curve for BNP as a predictor for in-hospital mortality showed that for the first 25 days, patients with BNP higher than 500 pg/mL had a higher mortality than patients with BNP lower than 500 pg/mL. When comparing HLOS, there is a statistically significant correlation (P = 0.0046). A similar scatter plot was prepared for ICULOS which showed there was a weak positive correlation (r = 0.199). Conclusion: Septic patients with in-hospital mortality had an average BNP of 908 pg/mL and statistically significant higher HLOS

Isolated T Wave Inversion in Lead aVL: An ECG Survey and a Case Report

Background. Computerized electrocardiogram (ECG) analysis has been of tremendous help for noncardiologists, but can we rely on it? The importance of ST depression and T wave inversions in lead aVL has not been emphasized and not well recognized across all specialties. Objective. This study\u27s goal was to analyze if there is a discrepancy of interpretation by physicians from different specialties and a computer-generated ECG reading in regard to a TWI in lead aVL. Methods. In this multidisciplinary prospective study, a single ECG with isolated TWI in lead aVL that was interpreted by the computer as normal was given to all participants to interpret in writing. The readings by all physicians were compared by level of education and by specialty to one another and to the computer interpretation. Results. A total of 191 physicians participated in the study. Of the 191 physicians 48 (25.1%) identified and 143 (74.9%) did not identify the isolated TWI in lead aVL. Conclusion. Our study demonstrated that 74.9% did not recognize the abnormality. New and subtle ECG findings should be emphasized in their training so as not to miss significant findings that could cause morbidity and mortality
