Cardiomyopathy III: Hypertrophic Cardiomyopathy

550
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Long-term Depression

33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Cranial Bones: Lateral View

7.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Summary

Cryptogenic temporal hollowing, a rare condition without prior trauma or surgery, was treated successfully with autologous fat grafting. This case highlights the need for further research into this unusual form of temporal hollowing.

Area of Science:

  • Plastic Surgery
  • Neurosurgery
  • Regenerative Medicine

Background:

  • Temporal hollowing is a known complication following coronal approach surgeries.
  • It typically results from atrophy of the superficial temporal fat pad.
  • Incidence can be as high as 6% after specific surgical procedures.

Purpose of the Study:

  • To present a rare case of cryptogenic temporal hollowing.
  • To investigate the diagnostic findings in a patient with no history of trauma or surgery.
  • To report the successful treatment outcome using autologous fat grafting.

Main Methods:

  • A 22-year-old male patient presented with unexplained temporal hollowing.
  • Diagnostic workup included magnetic resonance imaging (MRI) and electromyography (EMG).
  • Treatment involved autologous fat injection using the modified Coleman technique.

Main Results:

  • MRI revealed fatty degeneration of the temporalis muscle.
  • EMG and nerve conduction studies showed no neurological abnormalities.
  • The patient underwent successful autologous fat grafting for temporal hollowing.

Conclusions:

  • Cryptogenic temporal hollowing can occur without apparent cause.
  • Autologous fat grafting is a viable treatment option for temporal hollowing.
  • Further investigation into the etiology of cryptogenic temporal hollowing is warranted.
