Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Area of Science:

  • Ophthalmology and Genetics
  • Neurology and Psychiatry

Background:

  • Hallgren's syndrome is a rare genetic disorder.
  • It is characterized by a combination of retinitis pigmentosa and sensory-neural hearing loss.
  • Psychiatric manifestations are less commonly associated but have been reported.

Purpose of the Study:

  • To report two unique cases of Hallgren's syndrome.
  • To highlight the co-occurrence of psychiatric disorders with this rare syndrome.
  • To provide a brief overview of Hallgren's syndrome for clinical awareness.

Main Methods:

  • Case report methodology.
  • Clinical presentation and diagnostic evaluation of two patients.
  • Review of existing literature on Hallgren's syndrome.

Main Results:

  • Case 1: Hallgren's syndrome with retinitis pigmentosa, sensory-neural hearing loss, and schizophrenia.
  • Case 2: Hallgren's syndrome with retinitis pigmentosa, sensory-neural hearing loss, and major depression.
  • Both cases illustrate the variable phenotypic expression of Hallgren's syndrome.

Conclusions:

  • Hallgren's syndrome can present with significant psychiatric comorbidities.
  • Schizophrenia and major depression are potential co-occurring conditions.
  • Increased clinical vigilance is warranted for psychiatric symptoms in patients with Hallgren's syndrome.
