Sex Linked Disorders01:43

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Disorders of the Male Reproductive System01:20

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...

    Summary

    Extensive colorectal surgery can cause sexual dysfunction in men. This study reviews nerve anatomy and surgical techniques to help prevent these post-operative sexual disorders.

    Area of Science:

    • Urology
    • Colorectal Surgery
    • Neuroanatomy

    Context:

    • Sexual dysfunction is a common complication following extensive colorectal operations, affecting 16-100% of patients.
    • A significant percentage of men (21.3%) in the study cohort reported sexual disorders post-surgery.

    Purpose:

    • To present an anatomical survey of the nerve supply crucial for sexual function.
    • To highlight surgical tactics and techniques that can prevent damage to vital nervous structures during colorectal procedures.

    Summary:

    • The study details the anatomical basis of sexual function related to colorectal surgery.
    • It emphasizes the importance of preserving specific nerve pathways during surgical interventions.
    • Findings aim to reduce the incidence of post-operative sexual dysfunction.
