World Spinal Cord Injury Day

 

 

 
 

Charles-Édouard Brown-Séquard (1817–1894), a French physiologist, is credited with describing Brown-Séquard syndrome.

In 1849, Brown-Séquard first described the neurological effects of hemisection of the spinal cord in animal experiments.

                                 Animal Experiments Shed Light On Spinal Cord Injury

Brown-Séquard initially reported his findings in animal models, especially on guinea pigs, rabbits, and dogs.

 He demonstrated that a unilateral lesion of the spinal cord produced a characteristic pattern of deficits:

Ipsilateral paralysis (motor loss)

Ipsilateral loss of proprioception and fine touch

Contralateral loss of pain and temperature sensation

His findings were revolutionary in linking specific neurological deficits to localized spinal cord injuries

 
 
By the mid-19th century, his observations were confirmed in human clinical cases of spinal cord injury.

World Sexual Health Day


One of the oldest surviving medical papyri 

The papyrus is essentially a medical textbook of ancient Egypt. 

Provides direct insight into how the ancient Egyptians understood disease and healing

Location Today: Preserved at the University of Leipzig, Germany (acquired by Egyptologist Georg Ebers in 1873–74).

                                                 

                                           Chlamydia Trachomatis In Ebers Papyrus

The Ebers Papyrus (c. 1550 BCE) is a 20-meter-long ancient Egyptian medical scroll, one of the oldest known medical documents. It describes hundreds of diseases and treatments — including eye infections like trachoma, which links it historically to Chlamydia trachomatis. 





                                                    Chlamydia Trachomatis 

Chlamydia trachomatis has different strains (serovars) causing different diseases:

  • A, B, Ba, C → Trachoma (chronic eye infection → blindness).
  • D–K → Urogenital infections (most common cause of bacterial STDs worldwide).
    • Cervicitis, urethritis, pelvic inflammatory disease (PID), infertility.
    • Can also cause neonatal conjunctivitis & pneumonia.
  • L1, L2, L3 → Lymphogranuloma venereum (LGV), an invasive STD causing genital ulcers and lymph node swelling.

Current Events

World Sexual Health Day (WSHD) is observed annually on September 4, first established in 2010 by the World Association for Sexual Health (WAS)

Raises global awareness about sexual health, rights, justice, and pleasure as fundamental human aspects

World Leukemia Day

 

Leukemia was first described in the early 19th century by Velpeau and formally named by Virchow in 1845. Progress accelerated in the 20th century with chemotherapy and the discovery of the Philadelphia chromosome.




First chromosomal abnormality identified in cancer.

 Provided direct evidence of a genetic cause for cancer.

1960 – Philadelphia, USA

  • Peter Nowell (pathologist) and David Hungerford (graduate student) at the University of Pennsylvania and the Fox Chase Cancer Center discovered a small abnormal chromosome consistently present in patients with chronic myeloid leukemia (CML).
  • They named it the Philadelphia chromosome after the city where it was discovered.
  • This was the first consistent chromosomal abnormality linked to a human cancer





Current Events

World Leukemia Day is observed annually on  September 4. It’s a coordinated global campaign led by patient advocacy groups worldwide
