Hernial Pelvic Floor Prolapse Spontaneous development of perineal hernias is a very rare condition and many techniques have been used for repairing the pelvic floor defect. This case study is of a patient with a massive perineal hernia.
The patient is a 68-year-old healthy female (shown above) with a two-year history of posterior perineal bulging that caused discomfort and prevented her from sitting down comfortably. It was associated with obstipation and fecal incontinence. She had no history of perineal surgeries nor vaginal deliveries. Examination showed a herniation of a 22cm x 16 cm in the right buttock. Digital anal examination showed a laterally displaced rectum. A defect in the levator ani muscle group, along the posterior-lateral wall of the rectum on the right side, could be seen. Computerized tomography (CT) scan and magnetic resonance imaging (MRI) of the lower pelvis showed a large protruding mass containing herniated loops of the sigmoid colon and part of the rectum. The right levator ani muscle could not be recognized. During surgery, the sigmoid loop and small bowel were easily cut off the hernia sac, the hernia was removed, the levator ani defect was repaired and the rectum was restored. A vacuum drain was inserted and the skin was closed with stitches. The patient was discharged uneventfully from hospital on the sixth day after the operation. Five years on, the patient is moving her bowels regularly, has no fecal incontinence, nor any evidence of perineal hernia recurrence. Tetanus and Botulism, pg. 304: Under anaerobic conditions, spastic paralysis caused by the bacterium Clostridium tetani- causing tetanus. It blocks the neurotransmitter Gylycine. This results in overstimulation of muscles and excessive muscle contractions. C. tetani, is common soil organism that withstands harsh environmental conditions and can survive for a long time. We get immunized with the tetanus shot and need to get periodic booster shots to guarantee protection.
Botulism is caused by a toxin produced by the bacterium Clostridium botulinum. This toxin prevents the release of acetylcholine at synaptic terminals and leads to muscular paralysis. It is also common in the environment and produces its toxin only in anaerobic conditions. Mostly we get this toxin from canned foods that are not processed correctly. This is especially dangerous for children under 6 months, if they eat unpasteurized honey.
Botulism is also used in cosmetic Botox to remove wrinkle lines.
Paralysis of the diaphragm, pg. 344: Paralysis of diaphragm is most common in spinal cord injuries at or above 4th cervical vertebra. It can also be caused by injuring the brain, spinal cord, or phrenic nerves. When paralyzed, the diaphragm cannot contract, no air is exchanged in lungs. Polio was a common cause in earlier times. It can be treated now with a ventilator and other respiratory techniques, but in earlier times they used an Iron Lung. It was a chamber where the air pressure was cyclically decreased to facilitate inhalation and then increased to facilitate exhalation.
Hernias, pg. 349: A hernia is a condition in which a portion of the viscera protrudes through a weekend point of muscular wall of abdominopelvic cavity. If the herniated portion swells and becomes trapped, blood flow will diminish and this portion of the intestine could die. Inguinal hernia is most common because inguinal region is one of the weakest areas of abdominal wall. Males get this more often, because their inguinal canals are larger to allow sperm to pass. You can get them by lifting really heavy objects. They can either by direct inguinal hernia, where loop of small intestine protrudes into superficial inguinal ring, but not entire length of inguinal canal. Mostly seen in middle-aged males with protruding abdomens. It can also be an indirect inguinal hernia where herniation travels through the entire inguinal canal and may extend all way to scrotum. Usually occurs in younger males. A femoral hernia in in upper thigh, just below inguinal ligament. Medial part of femoral triangle is weak and prone to stress injury. Women more commonly develop these because of their wide hips.
Episiotomy, pg. 349: surgical incision made in perineal skin and soft tissue between vagina and anus during childbirth to prevent tearing and help get baby out. Lately it has come into question on whether it needs to be used as much as it has. 25-30% of women can benefit from procedure.

This recent study conducted by Kaiser Permanente of Southern California is the most extensive research on the subject to date. It talks about the disorders studied, the study purpose and treatment options available.
