Gene Conversion02:08

Gene Conversion

10.7K
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Conversion of Units

36.8K
Sometimes, there is a need to convert from one unit to another one. For instance, reading a cookbook in which quantities are expressed in units of liters or ounces may require conversion of quantities to cups. Or, when looking up directions on how to get to a location, we may be interested to know how many miles we are going to walk. In this case, we would have to convert units of feet or meters to miles.
The first step in the unit conversion is to list the given units and the units required...

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Conversion of Alcohols to Alkyl Halides

8.5K
This lesson delves into the conversion of alcohols to corresponding alkyl halides and the mechanism of action for different reagents. Typically, the hydroxyl group is first protonated to convert it to a stable leaving group. Consequently, based on the starting alcohol, the mechanism undergoes either of the nucleophilic substitution routes, SN1 or SN2. Tertiary alkyl halides are made using the two-step SN1 mechanism that occurs via a carbocation intermediate, which is stabilized by...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

5.2K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Summary

This study highlights two cases where patients initially diagnosed with conversion disorder in the ambulance were later found to have acute stroke. Conversion disorder is a condition where physical symptoms lack a clear medical cause, but stroke can present with similar symptoms, leading to diagnostic confusion. The authors emphasize the need for emergency physicians to consider stroke in patients with atypical presentations and to perform thorough neurological assessments. The study underscores the importance of accurate diagnosis in emergency settings to avoid delays in treatment.

Area of Science:

  • Neurology and stroke diagnosis
  • Emergency medicine and triage
  • Psychosomatic disorders in clinical settings

Background:

Conversion disorder is a recognized condition within psychiatric and neurologic fields, often linked to psychosomatic symptoms. It is more common in women and populations with limited education or lower socioeconomic status. Despite this, a significant proportion of patients diagnosed with conversion disorder are later found to have organic neurological or non-psychiatric conditions. This diagnostic uncertainty creates a challenge in emergency settings. Existing knowledge highlights the overlap between conversion disorder and other neurological disorders. However, the extent to which stroke can mimic conversion disorder is not well understood. No prior work had resolved how frequently stroke is misdiagnosed as conversion disorder during initial assessments. This gap motivated the need to explore cases where stroke was initially mistaken for conversion disorder. The authors aimed to shed light on the clinical presentation of stroke that closely resembles conversion disorder. By doing so, they hoped to improve diagnostic accuracy in emergency departments.

Purpose Of The Study:

The study aimed to highlight the diagnostic challenges of distinguishing stroke from conversion disorder in emergency settings. The authors sought to present two cases where stroke was initially misdiagnosed as conversion disorder. They wanted to emphasize the importance of thorough neurological assessment in patients with suspected conversion disorder. The motivation for the study arose from the high rate of misdiagnosis in such cases. The authors proposed that stroke can present with symptoms mimicking conversion disorder, leading to diagnostic errors. They also aimed to raise awareness among emergency physicians about this possibility. The study's goal was to improve early recognition of stroke in patients with atypical presentations. By doing so, they hoped to reduce the risk of delayed treatment and poor outcomes.

Main Methods:

The authors described two case reports of patients who presented with symptoms resembling conversion disorder. Both patients were initially diagnosed with conversion disorder during ambulance transport. Upon arrival at the emergency department, further neurological assessments were conducted. The patients underwent brain imaging and other diagnostic tests to rule out stroke. The authors analyzed the patients' clinical presentations and diagnostic processes. They compared the initial and final diagnoses to identify discrepancies. The study focused on the diagnostic journey of each patient. The authors emphasized the importance of re-evaluating patients diagnosed with conversion disorder.

Main Results:

In both cases, the initial diagnosis of conversion disorder was later found to be incorrect. Brain imaging revealed evidence of acute stroke in both patients. The first patient had a right middle cerebral artery infarction. The second patient exhibited signs of a left thalamic stroke. The symptoms of both patients closely resembled those of conversion disorder. The authors noted that the patients' neurological deficits were consistent with stroke. The misdiagnosis occurred due to the similarity in symptom presentation. The study highlighted the need for careful neurological evaluation in such cases.

Conclusions:

The authors concluded that stroke can present with symptoms that closely mimic conversion disorder. This similarity can lead to misdiagnosis in emergency settings. The study emphasized the importance of thorough neurological assessment. The authors proposed that emergency physicians should consider stroke in patients with suspected conversion disorder. They suggested that brain imaging should be performed to confirm the diagnosis. The findings indicate that stroke should not be overlooked in such cases. The authors recommended a higher index of suspicion for stroke in patients with atypical presentations. Their conclusion aligns with the need to improve diagnostic accuracy in emergency departments.

Stroke can cause neurological deficits that mimic psychosomatic symptoms, such as sudden weakness or sensory loss, leading to diagnostic confusion.

Brain imaging, including MRI or CT scans, was used to identify acute stroke in both patients.

Because stroke can present with similar symptoms, and misdiagnosis may delay treatment, leading to worse outcomes.

Emergency physicians should perform detailed neurological exams and consider stroke in patients with atypical presentations.

Both patients received appropriate stroke treatment after the initial misdiagnosis was corrected.

The authors recommend a higher index of suspicion for stroke and thorough neurological evaluation in patients with suspected conversion disorder.
