A 10-year-old boy with cystic fibrosis (CF) (DeltaF508/G551D mutation) underwent an uneventful elective interval laparoscopic appendectomy. During routine laparoscopic inspection of the abdomen and groins, congenital bilateral absence of the vas deferens was noted. Pictures of the patient's internal inguinal ring noted at time of laparoscopy are presented and compared with a similar-aged patien...

BACKGROUND Vitamin A deficiency (VAD) is associated with increased mortality. To prevent VAD, WHO recommends high-dose vitamin A supplementation (VAS) every 4-6 months for children aged between 6 months and 5 years of age in countries at risk of VAD. The policy is based on randomized clinical trials (RCTs) conducted in the late 1980s and early 1990s. Recent RCTs indicate that the policy may hav...

Insertion of a copper wire into the vas deferens of male rats released 4 micrograms of copper in themid portion of the vas deferens in two days time. In urethral and epidymal segments of the vas deferens copper released was less than one microgram. The present study demonstrates that the in vivo effects of 4 microgram of copper in 2 days time in the vas deferens are enough to induce antifertili...

Background. A patient- and assessor-blinded randomized controlled trial was conducted to examine the effectiveness of auricular transcutaneous electrical nerve stimulation (TENS) in relieving posthysterectomy pain. Method. Forty-eight women who had undergone a total abdominal hysterectomy were randomly assigned into three groups (n = 16 each) to receive either (i) auricular TENS to therapeutic ...

Vasicine (VAS), a potential natural cholinesterase inhibitor, exhibited promising anticholinesterase activity in preclinical models and has been in development for treatment of Alzheimer's disease. This study systematically investigated the in vitro and in vivo metabolism of VAS in rat using ultra performance liquid chromatography combined with electrospray ionization quadrupole time-of-flight ...

Visual analogue scales (VAS) of sensory intensity and affective magnitude were validated as ratio scale measures for both chronic and experimental pain. Chronic pain patients and healthy volunteers made VAS sensory and affective responses to 6 noxious thermal stimuli (43, 45, 47, 48, 49 and 51 degrees C) applied for 5 sec to the forearm by a contact thermode. Sensory VAS and affective VAS respo...

To determine the reliability and concurrent validity of a visual analogue scale (VAS) for disability as a single-item instrument measuring disability in chronic pain patients was the objective of the study. For the reliability study a test-retest design and for the validity study a cross-sectional design was used. A general rehabilitation centre and a university rehabilitation centre was the se...
