Botulin Toxin in the Treatment of Nonrelaxing Puborectalis Syndrome
TLDR
Botulin toxin injection in the external anal sphincter is a simple, easy and safe method for the treatment of nonrelaxing puborectalis syndrome and is to be considered after biofeedback has failed. Expand
A study of the effect of distension of the rectosigmoid junction on the rectum and anal canal with evidence of a rectosigmoid-rectal reflex.
  • A. Shafik
  • Medicine
  • The Journal of surgical research
  • 1 March 1999
TLDR
It is postulated that stools passing from the sigmoid colon to the rectum distend the RSJ and evoke the rectosigmoid-rectal reflex, which produces rectal contraction. Expand
Vagino-levator reflex: description of a reflex and its role in sexual performance.
  • A. Shafik
  • Medicine
  • European journal of obstetrics, gynecology, and…
  • 1 June 1995
TLDR
The levator contraction upon penile thrusting leads to genital responses that could facilitate sexual performance that comprise widening of the vaginal introitus, vaginal elongation and ballooning of the upper vagina as well as uterine elevation. Expand
Study of the electrical and mechanical activity of the rectum: an experimental study.
  • A. Shafik
  • Biology, Medicine
  • European surgical research. Europaische…
  • 1994
TLDR
The results suggest that PP start at the 3rd electrode, which corresponds anatomically to the rectosigmoid junction (RSJ), which seems to be the site of a pacemaker triggering the PP that pace the AP which initiate the rectal contractile activity. Expand
MECHANISM OF EJECTION DURING EJACULATION: IDENTIFICATION OF A URETHROCAVERNOSUS REFLEX
TLDR
The mechanism of bulbocavernosus muscle (BCM) contraction, once the seminal fluid reaches the bulbous urethra, is investigated and it is suggested that the urethrocavernosUS reflex be included in current andrologic investigations for patients with ejaculatory disorders. Expand

  • A. Shafik
  • Medicine
  • Diseases of the colon and rectum
  • 1 June 1995
TLDR
Perianal fat injection is effective in treatment of partial fecal incontinence with perianal injection of autologous fat, simple, easy, cost-effective, and performed on an outpatient basis. Expand
Contraceptive efficacy of polyester-induced azoospermia in normal men.

F fertile men can be rendered azoospermic by wearing the polyester sling, and it is a safe, reversible, acceptable and inexpensive method of contraception in men. Expand
Vaginocavernosus reflex. Clinical significance and role in sexual act.
  • A. Shafik
  • Medicine
  • Gynecologic and obstetric investigation
  • 1993
TLDR
The reflex cavernosus muscle contraction on vaginal distension during the sexual act seems to enhance both the clitoris and penile erection and is suggested to support the head during its descent and prevent vaginal and perineal tears. Expand
