Trophic Levels01:35

Trophic Levels

37.5K
All organisms in an ecosystem occupy a trophic level in the food chain. The lowest level consists of primary producers, which synthesize their food from either solar or chemical energy. Each subsequent level obtains energy from the levels below. Detritivores can occupy any of the levels above primary producers.

Trophic Efficiency00:46

Trophic Efficiency

25.1K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

Nephrotic Syndrome I : Introduction

609
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: Introduction01:30

Acute Coronary Syndrome I: Introduction

933
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...

Irritable Bowel Syndrome I: Introduction

996
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Restless Leg Syndrome and Night Terrors01:27

Restless Leg Syndrome and Night Terrors

535
Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

Summary

This case study highlights trigeminal trophic syndrome (TTS) on the scalp, initially misdiagnosed. Accurate diagnosis required reviewing patient history and understanding TTS, differentiating it from other scalp conditions.

Area of Science:

  • Neurology
  • Dermatology

Background:

  • Trigeminal trophic syndrome (TTS) is a rare condition characterized by facial ulcerations.
  • Scalp involvement is an uncommon presentation of TTS.

Observation:

  • A 69-year-old woman presented with scalp lesions.
  • Pityriasis amiantacea was initially considered in the differential diagnosis.

Findings:

  • The final diagnosis was trigeminal trophic syndrome (TTS) of the scalp.
  • A thorough review of pathological history and TTS knowledge was crucial for accurate diagnosis.

Implications:

  • This case underscores the importance of considering TTS in scalp ulcerations.
  • Recognizing TTS aids in appropriate management and differentiates it from other dermatological conditions.
