ABSTRACT
Mercury, a ubiquitous heavy metal, poses a significant threat to human health. Intravenous mercury poisoning is an uncommon but critical medical emergency. The nature and severity of its toxic effects depend on the form of mercury encountered: elemental, inorganic, or organic. It can affect almost all organ systems in the body. Chelating agents are the primary treatment for symptomatic mercury poisoning. This case report is about a 27-year-old male patient who presented to the emergency department with an alleged history of intravenous injection of mercury as an attempt at suicide, followed by breathlessness, chest pain, vomiting, and high-grade fever. He was managed with chelating therapy, non-invasive ventilation, and other supportive measures and was discharged home. After five days of discharge, he presented with fever and rashes and was diagnosed with toxic epidermal necrolysis (TEN). In spite of all aggressive management, he succumbed to death after four days of re-admission. Early intervention can significantly improve the chances of recovery. However, even with successful treatment, some individuals may experience long-term complications.
ABSTRACT
Nonketotic hyperglycemia hemichorea-hemiballismus syndrome (NHH) is an uncommon neurological condition linked to poorly managed diabetes mellitus (DM). It presents with spontaneous, erratic movements that impact just one side of the body. Our case of NHH was of a 76-year-old female with uncontrolled type 2 DM, ischemic heart disease, and dilated cardiomyopathy. Despite previous treatment for similar symptoms, the patient developed left-sided choreo-ballistic movements. Despite difficulties obtaining clear magnetic resonance imaging (MRI) due to involuntary movements, the image revealed T1 hyperintense signals in the right lentiform nucleus and subtle signals in the left lentiform nucleus and external capsule. Management included insulin, tetrabenazine, haloperidol, lorazepam, and other adjunctive therapies, resulting in symptom resolution by the fourth day. This case underscores the importance of considering NHH in patients with uncontrolled DM presenting with abnormal movements, highlighting the challenges in imaging due to involuntary movements and emphasizing the need for aggressive glycemic control and treatment strategies.
ABSTRACT
The aim of this review article is to outline the effectiveness of using bedside ultrasound to measure the optic nerve sheath diameter (ONSD) in order to identify variations in intracranial pressure (ICP) and subsequently avoid the complication of secondary brain injury in patients with traumatic brain injury (TBI), who are admitted to an emergency department (ED). Reputable publications and numerous studies demonstrate the problem's exponential rampancy and pervasiveness. In a TBI patient, the emergence of secondary brain damage has been recognized as a serious emergency. It is believed that secondary brain damage is caused by an abnormally high ICP. High levels of ICP can be measured using both invasive and non-invasive approaches. ONSD measurement via bedside ultrasound has been identified as a quick, useful technique to be used in the ED to avoid potential morbidity and mortality owing to secondary brain injury.
ABSTRACT
Pericardial effusion is a rare manifestation of tuberculosis (TB) that can present as a life-threatening emergency. It poses a diagnostic challenge, as its clinical presentation may mimic other more common causes of acute cardiac emergencies. Emergency physicians should maintain a high index of suspicion for tuberculosis, particularly in regions where the prevalence of the disease is high. This case report is about a 17-year-old girl who presented to the emergency room with dyspnea, chest discomfort, and hemodynamic instability consistent with cardiac tamponade. Urgent diagnostic procedures, including point-of-care ultrasound (POCUS) and pericardiocentesis, were crucial to the successful management of this patient.
ABSTRACT
Scorpion sting cases are everyday encounters in the Emergency Department (ED). However, scorpion sting-induced systemic manifestations are rarely seen. Signs and symptoms of envenomation involve the central nervous system, stimulation of the autonomic nervous system and rarely respiratory and heart failure leading to death. Cardiovascular manifestations are particularly prominent following stings by the Indian red scorpion. This case report is of an 18-year-old male patient who presented to ED with complaints of scorpion sting. Twelve lead electrocardiography (ECG) done was suggestive of acute inferior wall myocardial infarction with raised cardiac markers. He also had autonomic dysfunction in the form of hypertension, hypothermia and priapism. He was treated with an alpha-blocker, dual antiplatelets and analgesics. ECG changes reverted to normal the next day, and he was discharged. So, the anticipation of life-threatening complications of scorpion stings plays a vital role in the treatment and prognosis of patients presenting to ED.
ABSTRACT
Selective serotonin reuptake inhibitors (SSRIs) are the most common antidepressants used due to their comparatively less cardiotoxic effects than tricyclic antidepressants. Corrected QT interval (QTc) prolongation is the most common electrocardiography (ECG) change that has been encountered with SSRI overdose. This case report is about a 22-year-old woman who was brought to the emergency department (ED) with an alleged history of consumption of 200 mg of escitalopram. Her ECG showed T-wave inversions in anterior leads one to five, which reverted (in leads four and five) the next day with supportive management. After 24 hours, she developed dystonia, which resolved with mild doses of benzodiazepine. Hence, ECG changes like T-wave inversions may occur even with a small overdose of an SSRI without any significant adverse effects.
