Diphtheria01:28

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Anthelminthic Agents01:15

Anthelminthic Agents

Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin

Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
The binding of dantrolene to the RYR1...
Encephalitis ll: Pathophysiology01:26

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Area of Science:

  • Infectious Diseases
  • Parasitology
  • Neurology

Background:

  • Trichinellosis is a parasitic zoonosis caused by Trichinella spp. nematodes.
  • Neurotrichinellosis is a severe, potentially fatal complication, particularly with Trichinella spiralis.
  • Nervous system involvement occurs via direct or indirect parasite mechanisms, with inflammatory cells like eosinophils playing a key role.

Purpose of the Study:

  • To review the mechanisms, clinical presentations, diagnosis, and treatment of neurotrichinellosis.
  • To highlight the significance of encephalopathy as a leading cause of mortality.
  • To emphasize diagnostic approaches and therapeutic strategies.

Main Methods:

  • Review of literature on Trichinella spp. and neurotrichinellosis.
  • Analysis of clinical manifestations, diagnostic criteria, and treatment outcomes.
  • Discussion of pathomechanisms involving direct and indirect parasite effects on the nervous system.

Main Results:

  • Encephalopathy, neuromuscular disturbances, and ocular involvement are common presentations.
  • Imaging (CT/MRI) and serology aid diagnosis in individuals with relevant exposure history (e.g., raw pork consumption).
  • Muscle biopsy provides definitive diagnosis, while albendazole/mebendazole with corticosteroids are recommended treatments.

Conclusions:

  • Neurotrichinellosis requires prompt diagnosis and management due to its potential severity.
  • Understanding parasitic mechanisms and inflammatory roles is crucial for effective treatment.
  • Anthelmintic therapy combined with corticosteroids is essential for managing this parasitic neurological complication.
