Materials and Methods: A retrospective chart review was performed of children undergoing hydrocele repair at our institution between 1998 and 2006. Operative Nec-1s cell line reports were reviewed by 2 investigators and intraoperative findings were recorded for statistical analysis relating age and findings at the time of the procedure using logistic regression and ROC analysis. Laterality and recurrence rates were also noted.

Results: In this retrospective chart review 82.1% of hydroceles in children older than 10 years had intraoperative findings

consistent with noncommunicating hydrocele and 86.4% in children older than 12 years were noncommunicating. One hydrocele in the age group older than 12 years was communicating and the history was suggestive of communication. Age was significantly associated

with a patent processus vaginalis (OR 0.783, p <0.0001).

Conclusions: It is possible in children older than 12 years to repair hydroceles through a scrotal incision unless the clinical history is suggestive of Y-27632 order a communication. Children younger than 12 years should undergo inguinal exploration for hydrocele repair.”
“Experiences of odours at meals are thought to affect food preference in many animals. To study appetite modulation by odours, we established a new experimental system based on the modification of a previous method, where flies fed sucrose flavoured with D-limonene subsequently showed reduced appetite to plain sucrose. In this new experimental system, a fly population was divided into two groups: (1) the “”simultaneous”" group of flies was exposed

to D-limonene BV-6 order and sucrose simultaneously for 10 min, and (2) the “”separate”" group of flies was exposed to sucrose alone for 10 min, and 1 h later, to limonene for 10 min. The appetite of flies in the “”separate”" group for sucrose was unaffected by the experiment, but the appetite of flies in the “”simultaneous”" group was significantly decreased, and this effect lasted for >= 3 days. To investigate if this appetite modulation by D-limonene was based on long-term memory formation (protein synthesis), we examined the effects of the protein synthesis inhibitor, cycloheximide. Injection of cycloheximide 1 h after exposure to limonene and sucrose inhibited the appetite suppression in the “”simultaneous”" group of flies. In addition, to exclude the possibility that D-limonene exerted its effect through taste, rather than odour, we examined the effect of removing of the olfactory organs, antennae and maxillary palps on appetite modulation by D-limonene. When the olfactory organs were removed, no reduction in appetite was observed in the flies in the “”simultaneous”" group, indicating olfaction. In our new and effective appetite-modulation system for flies, modulation of appetite by olfactory detection of D-limonene was shown. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
