Partial Fractions01:28

Partial Fractions

227
A partial fraction is a component of a rational expression represented as the sum of simpler fractions. When a rational function is expressed as a ratio of two polynomials, it can often be decomposed into a sum of fractions whose denominators are simpler polynomials, typically linear or irreducible quadratic factors. This process is called partial fraction decomposition, and it is used to simplify complex expressions for integration, solving equations, or analysis.Partial fraction decomposition...

Dosage Regimens: Partial Pharmacokinetic Parameters

180
It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...

Drug Dosing: Infants and Children

312
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Epilepsy and Seizures: Overview

1.4K
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Mixtures of Gases: Dalton's Law of Partial Pressures and Mole Fractions

44.3K
Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each gas in a mixture exerts the same pressure that it would exert if it were present alone in the container. The pressure exerted by each individual gas in a mixture is called its partial pressure.

Dalton's Law of Partial Pressure01:11

Dalton's Law of Partial Pressure

2.6K
The partial pressure of a gas is a measure of the thermodynamic activity of the gas's molecules. The pressure that a gas would create if it occupied the total volume available is called the gas's partial pressure. If two or more gases are mixed together in a container, the molecules move randomly and collide with each other, causing them to reach thermal equilibrium. When the gases have the same temperature, their molecules have the same average kinetic energy. Thus, each gas obeys the...

Area of Science:

  • Neurology
  • Pediatrics
  • Epileptology

Context:

  • Analysis of 101 patients with partial epilepsy.
  • Study conducted at Neuropediatric Clinics of Hospital General Base Cayetano Heredia.
  • Data collected retrospectively and prospectively from January 1984 to July 1988.

Purpose:

  • To analyze the characteristics and causes of partial epilepsy in pediatric patients.
  • To determine the prevalence of idiopathic and symptomatic epilepsy in this cohort.
  • To identify common etiologies of symptomatic epilepsy in young children.

Summary:

  • 19% of cases were classified as idiopathic epilepsy.
  • 7.7% represented benign childhood epilepsies.
  • Symptomatic epilepsies were primarily linked to perinatal issues, CNS infections, and tuberculosis granulomas.

Impact:

  • Provides insights into the epidemiology of pediatric partial epilepsy.
  • Highlights the importance of identifying underlying causes for effective management.
  • Contributes to understanding epilepsy etiology in developing countries.
