The purpose of this study was to investigate the association between two genetic polymorphisms (PvuII and XbaI restriction fragment length polymorphisms, RFLPs) of the estrogen receptor-alpha (ER1) gene and the quantitative ultrasound (QUS) parameters at the calcaneus. ⋯ The results suggest that the PvuII and XbaI RFLPs of the ER1 gene may be genetic factors that affect QUS at the calcaneus.

Effects of preoperative gabapentin on postoperative nausea and vomiting after open cholecystectomy: a prospective randomized double-blind placebo-controlled study.
To evaluate the effect of gabapentin on the incidence and severity of postoperative nausea and vomiting (PONV) after open cholecystectomy. ⋯ Our data show that gabapentin not only reduced PONV after open cholecystectomy, but also reduced the need for additional postoperative analgesics.

Additional intra-operative sedation may help improve acceptability and comfort of anaesthesia in patients undergoing minor anorectal (perianal) procedures under spinal saddle block. This observational study was done to determine which patients request sedatives and to what extent sedatives affect the patients' recovery. ⋯ Female gender, younger age, lower body weight and lower BMI were associated with higher subjective requirements for sedation. The use of sedation showed prolongation of time to first mobilization and micturition and a higher incidence of nausea.

To evaluate the accuracy of urine sample collection methods among children suspected of having urinary tract infections. ⋯ Suprapubic aspiration showed the lowest contamination rate and sterile urine bag showed the highest contamination rate among 4 methods of urine sample collection. Contaminated specimens, needed to be repeated and this procedure increased the cost of urine culture. In conclusion, measures should be taken to reduce the contamination rate in our center. This is an area where further investigation is required.

The objective of the present study was to investigate smoking habits of Iranian dental students in relation to their background characteristics and oral self-care (OSC). ⋯ Smoking among Iranian dental students is similar to their socioeconomic group, and is associated with the characteristics of their background, such as gender and father's level of education, as well as the quality of OSC. The results indicate a need to include smoking cessation education and public health activities in the dental curriculum to provide future health care professionals and role models for patients with adequate training in up-to-date patient management to control smoking.
