Meralgia paraesthetica following laparoscopic inguinal hernia repair. An anatomical analysis.

Entrapment of the lateral cutaneous nerve of the thigh (LCNT) is a recognized complication of laparoscopic hernia repair. In our first 10 patients in a series of 30 laparoscopic herniorrhaphies we encountered two cases of meralgia paraesthetica, leading us to review our surgical technique and analyze the local anatomy in 20 LCNT cadaver dissections. The distances of the LCNT from fixed anatomical points were analyzed and safe margins of mesh placement at laparoscopic herniorrhaphy were defined.

Consensus at zero acquaintance: replication, behavioral cues, and stability.

That observers tend to agree in their ratings of a target even if they have never interacted with that target has been called consensus at zero acquaintance. The basic finding that consensus is highest for judgments concerning a target's degree of extraversion (EV) and somewhat weaker for judgments of conscientiousness is replicated. Several potential observable cues that might be used by judges when rating targets are examined. The finding that ratings of physical attractiveness correlate with judgments of EV is replicated. In Study 1, rapid body movements and smiling were also found to correlate with EV judgments. The level of consensus declined when initially unacquainted Ss interacted one-on-one (Study 2), but did not decline--and even increased--when Ss interacted in a group (Study 3). Ss judged as extraverted at zero acquaintance were also seen as extraverted after interacting with others.

Ice-skating and roller disco injuries in Dublin.

A comparative study was carried out on a series of 72 ice-skating and 57 roller skating injuries over a sixteen month period. The average patient age was 20.5 years in the ice-skating group and 16.5 years in the roller skating group. Females predominated in both groups accounting for 72% of ice-skaters injured and 77% of roller skaters injured. Ice-skaters sustained more serious injuries than roller skaters as was evident from the significant difference in fracture numbers in the two groups. Ice-skating fractures accounted for 40% of all injuries while roller skating fractures were only 14% of their total injuries. The majority of ice-skating fractures occurred in females. As a result of our study we recommended several preventative measures.

alpha-chlorohydrin induced changes in sperm fertilizing ability in the rat: association with diminished sperm ATP levels and motility.

In the present study, alpha-chlorohydrin (ACH) (5, 10, 25, 50 and 75 mg/kg, po) was administered to rats and the effects on sperm ATP levels, sperm motility, and the ability of sperm to bind and penetrate rat oocytes were determined. Groups of rats were killed 5 days and 3 h following treatment. At both time points, sperm from ACH-treated rats (>/=10 mg/kg) had significantly lower levels of ATP when diluted in media containing glucose. No diminution of ATP was seen in sperm diluted in phosphate-buffered saline (PBS). Computer analysis of sperm motility indicated that straight-line velocity (VSL) was the most sensitive parameter to ACH treatment and was significantly decreased in rat sperm three hours after ACH exposure (25 mg/kg). A clear drop in percent penetration (35% vs. 85% in control) of zona-free rat oocytes by rat sperm of both ACH groups was observed at 10 mg/kg. Higher dose levels produced no significant further decrease in percent penetration. Overall, the fertilizing ability of sperm was highly sensitive to ACH doses that caused minor but significant changes in sperm ATP levels and no significant changes in motility. These data are consistent with the spermatozoan's need for an uncompromised energy supply to maintain its ability to bind and penetrate the oocyte.
