Summary
This case study highlights a rare, rapid progression of systemic sclerosis (SSc) leading to fatal cardiogenic shock in a young woman. It underscores the potential for fulminant SSc, even before diagnosis.
Area of Science:
- Rheumatology
- Cardiology
- Nephrology
Background:
- Progressive systemic sclerosis (PSS), now known as systemic sclerosis (SSc), is an autoimmune disease characterized by fibrosis, vascular abnormalities, and organ damage.
- While often indolent, SSc can present with rapid, severe manifestations, posing diagnostic and therapeutic challenges.
Observation:
- A 22-year-old female presented with severe hypertension, acute renal insufficiency, pericardial tamponade, and shock.
- Initial stabilization with pericardiocentesis was transient, followed by rapid deterioration.
Findings:
- The patient died of cardiogenic shock, with autopsy confirming progressive systemic sclerosis (PSS).
- This case illustrates a fulminant course of PSS, leading to death prior to definitive clinical diagnosis.
Implications:
- The case emphasizes the critical need to consider aggressive autoimmune processes in young patients with unexplained cardiorenal failure.
- Early recognition and management of fulminant SSc are crucial, despite diagnostic delays, to potentially improve outcomes.

Tumor Progression
7.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

mTOR Signaling and Cancer Progression
4.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Autophagic Cell Death
4.6K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

Overview of Cell Death
10.2K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Second Order systems II
412
In an underdamped second-order system, where the damping ratio ζ is between 0 and 1, a unit-step input results in a transfer function that, when transformed using the inverse Laplace method, reveals the output response. The output exhibits a damped sinusoidal oscillation, and the difference between the input and output is termed the error signal. This error signal also demonstrates damped oscillatory behavior. Eventually, as the system reaches a steady state, the error diminishes to zero.

First Order Systems

First-order systems, such as RC circuits, are foundational in understanding dynamic systems due to their straightforward input-output relationship. Analyzing their responses to different input functions under zero initial conditions reveals significant insights into system behavior.
When a first-order system is subjected to a unit-step input, its response is characterized by its transfer function. By applying the Laplace transform of the unit-step input to the transfer function, expanding the...
