Seizures l: Introduction

Seizures l: Introduction

Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...

Pulmonary Embolism I: Introduction

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Diabetic Ketoacidosis l: Introduction

Diabetic Ketoacidosis l: Introduction

DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...

Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Asthma III: Clinical Manifestations

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Summary

Neurologic symptoms like headache often precede eclamptic seizures in pregnant women. However, some women (17%) experience no warning signs, highlighting the need for vigilant monitoring during pregnancy.

Area of Science:

Obstetrics and Gynecology
Neurology
Maternal Health

Background:

Eclampsia is a severe complication of pregnancy characterized by seizures.
Identifying premonitory symptoms is crucial for timely intervention and improved maternal outcomes.

Purpose of the Study:

To characterize the symptoms that immediately precede eclamptic seizures.
To determine the frequency of prodromal symptoms in women with eclampsia.

Main Methods:

Prospective observational study conducted in a single center in Tanzania.
Inclusion of all women admitted with eclamptic seizures over a one-year period.
Standardized questioning regarding pre-seizure symptoms during admission.

Main Results:

Eclampsia occurred in 1.4% of deliveries (46 cases).
Headache (80%) and visual disturbances (45%) were the most common neurologic prodrome symptoms.
Twenty percent of women reported no neurologic symptoms preceding their eclamptic seizure.

Conclusions:

Neurologic symptoms frequently serve as early warning signs for eclampsia.
A significant minority (17%) of patients with eclampsia lack prodromal symptoms.
Recognizing premonitory symptoms can aid in the early detection and management of imminent eclampsia.
