Summary
Neurological dysfunction, including seizures and motor weakness, was reported following a Lebanese viper bite. This is the first documented case of such effects from Montivipera bornmuelleri.
Area of Science:
- Herpetology
- Toxicology
- Neurology
Background:
- The Lebanese viper (Montivipera bornmuelleri) is endemic to the Middle East, known for its potent venom causing hypercoagulable and cytotoxic effects.
- Neurological complications from snakebites are common, but specific neurotoxic effects of Montivipera bornmuelleri envenomation have not been previously documented.
Observation:
- A 31-year-old male presented with symptoms after a Montivipera bornmuelleri bite, including decreased consciousness, seizures, and right leg motor weakness.
- The patient also experienced urinary incontinence, erectile dysfunction, and groin anesthesia, while anal sensation was preserved.
Findings:
- Diagnostic tests, including brain and spinal MRI, electromyography, and routine laboratory workups, yielded normal results.
- Urodynamic studies revealed complete bladder areflexia, indicating a significant impact on autonomic bladder function.
Implications:
- This case highlights a previously unreported neurological manifestation of Montivipera bornmuelleri envenomation.
- Further research into the specific venom components and mechanisms responsible for neurotoxicity is warranted to improve patient management and develop targeted treatments.

01:26The Micturition Reflex
1.2K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
321
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

01:23Urinary Bladder
1.8K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

92
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
