Directing Effect of Substituents: meta-Directing Groups01:09

Directing Effect of Substituents: meta-Directing Groups

6.0K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Traumatic Memory01:20

Traumatic Memory

593
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Nephrotic Syndrome I : Introduction

689
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Acute Coronary Syndrome I: Introduction

1.1K
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

590
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

meta-Directing Deactivators: –NO2, –CN, –CHO, –⁠CO2R, –COR, –CO2H01:13

meta-Directing Deactivators: –NO2, –CN, –CHO, –⁠CO2R, –COR, –CO2H

6.8K
All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

Summary

Traumatic chiasmal syndrome can cause bitemporal hemianopia after head injury. This condition, often linked to frontal bone injury, requires consideration in differential diagnoses for visual field defects.

Area of Science:

  • Ophthalmology
  • Neurology
  • Trauma Surgery

Background:

  • Traumatic chiasmal syndrome is a rare condition.
  • Head injuries can lead to optic chiasm damage.

Purpose of the Study:

  • To report a case of traumatic chiasmal syndrome presenting with bitemporal hemianopia.
  • To compare this case with existing literature on traumatic chiasmal syndrome.

Main Methods:

  • Literature search of PubMed, MedIND, Taylor and Francis, and Wiley online library.
  • Systematic review and summarization of individual case reports of traumatic chiasmal syndrome.

Main Results:

  • Common features include frontal bone injury and anterior skull base fracture.
  • Bitemporal hemianopia presentation and visual acuity are variable and do not correlate with injury severity.
  • Isolated bitemporal hemianopia is rare, with unpredictable clinical improvement.

Conclusions:

  • Traumatic chiasmal syndrome should be considered in patients with bitemporal hemianopia post-head injury.
  • Frontal and anterior skull base fractures are key indicators.
