Several studies have examined how military-provided training affects post-service employment experience, but this study is the first to investigate that relationship for young men and women who enlisted in the "all-volunteer" era that began in 1974. Using data from the National Longitudinal Survey-Youth Cohort, the authors find that the transfer of skills to civilian employment was as high for military training as for civilian training (45-50 percent), once employer-provided training is excluded from consideration. Furthermore, within two years of their return to civilian life, those who received military training had higher earnings than those who received training in the civilian sector-a finding that contrasts with the results of studies of Vietnam veterans, but agrees with the results found for veterans of World War II and the Korean Conflict.

The potential effect of co-medication with phenobarbitone, primidone and carbamazepine on plasma and saliva concentrations of 5-(4-hydroxyphenyl)-5-phenylhydantoin (4-HPPH), the major metabolite of phenytoin in man and on the incidence of phenytoin-induced gingival overgrowth was investigated in a group of 36 adult epileptic patients. There were no significant differences in plasma or saliva concentrations of 4-HPPH or phenytoin in patients prescribed phenytoin alone, compared to those who received phenytoin with either phenobarbitone, primidone, or carbamazepine. In addition, the extent and the incidence of gingival overgrowth were similar in the 2 groups. The results suggest that chronic co-medication with other anti-convulsant drugs which induce phenytoin metabolism, does not affect the plasma or saliva 4-HPPB steady-state levels, nor the degree of gingival overgrowth in adult epileptic patients on therapy with phenytoin.

The incidence of CDI complicating IBD has fallen since 2007. CDI is no longer associated with worse short-term outcomes in patients with IBD than in those without. Patients with CDI and IBD have similar outcomes to those with IBD alone.

The aim of this study was to determine whether phenytoin (PHT) could be detected in gingival crevicular fluid (GCF), and to relate its concentration to both plasma level and degree of gingival overgrowth. 23 patients medicated with phenytoin for at least 6 months were clinically examined for signs of periodontal disease and gingival overgrowth. 12 patients out of these demonstrated clinically significant overgrowth and their plaque scores and gingival inflammation were greater than for the non-overgrowth group (p < 0.001). Phenytoin concentrations were determined by high performance liquid chromatography, and was detected in GCF. There was a significant correlation between the GCF and plasma phenytoin concentrations (p < 0.05), but it was not related to the extent of gingival overgrowth. Inflammation increased the GCF volume, but was not a determinant of GCF phenytoin concentration. It is concluded that effusion of phenytoin into GCF is regulated by the plasma levels of the drug, but its concentration in GCF is not related to the incidence of gingival overgrowth.
