The 5th outbreak of trichinosis occurred in a mountainous area of North Vietnam in 2012, involving 24 patients among 27 people who consumed raw pork together. Six of these patients visited several hospitals in Hanoi for treatment. Similar clinical symptoms appeared in these patients within 5-8 days after eating infected raw pork, which consisted of fever, muscle pain, difficult moving, edema, difficult swallowing, and difficult breathing. ELISA revealed all (6/6) positive reactions against Trichinella spiralis antigen and all cases showed positive biopsy results for Trichinella sp. larvae in the muscle. The larvae detected in the patients were identified as T. spiralis (Vietnamese strain) by the molecular analysis of the mitochondrial cytochrome c oxidase subunit III (cox3) gene.

Knowledge of the prevalence of human Toxoplasma gondii infection is required in the Republic of Korea. In this study, we surveyed the seroprevalence of T. gondii infection and analyzed the risk factors associated with seropositivity among residents in 2 administrative districts; Seoul and the island of Jeju-do, which have contrasting epidemiologic characteristics. Sera and blood collected from 2,150 residents (1,114 in Seoul and 1,036 in Jeju-do) were checked for IgG antibody titers using ELISA and for the T. gondii B1 gene using PCR. In addition, participants completed a questionnaire that solicited information on gender, age, occupation, eating habits, history of contact with animals, and travel abroad. The T. gondii B1 gene was not detected in all residents examined. However, ELISA showed 8.0% (89 of 1,114 sera) positive for IgG antibodies against T. gondii in Seoul and 11.3% (117 of 1,036 sera) in Jeju-do. In both districts, the positive rates were higher in males than in females, and those 40-79 years of age showed higher rates than other ages. In Seoul, residents older than 70 years of age showed the highest positive rate, 14.9%, whereas in Jeju-do the highest prevalence, 15.6%, was in those in their sixties. The higher seropositive rate in Jeju-do than in Seoul may be related to eating habits and occupations. The present results and a review of related literature are indicative of an increased seroprevalence of T. gondii in Korea in recent years.

Successive Multisite Peripheral Nerve Catheters for Treatment of Complex Regional Pain Syndrome Type I.

Complex regional pain syndrome (CRPS) type I is a painful and disabling syndrome that is accompanied by physical changes in the affected extremity. It generally occurs after trauma, manifesting as pain that is out of proportion to the inciting event. Treatment of the disorder is difficult, with many patients being refractory to multiple pharmacologic regimens. Regional anesthetic techniques, including neuraxial blockade, sympathetic blockade, Bier block, or peripheral nerve catheters, have been used with varying degrees of success. We describe, for the first time, the use of multiple peripheral nerve catheters to treat CRPS type I in a 10-year-old girl when multimodal pharmacologic regimens failed. At separate times, a peripheral nerve catheter was placed to treat CRPS of the distal left lower extremity as well as the right upper extremity. The goal of this therapy was to relieve pain and thereby allow the reinitiation of intensive physical therapy. A continuous infusion of 0.1% ropivacaine was infused via the catheters for ?60 hours. The patient was subsequently able to participate in physical therapy as well as activities of daily living with improved eating, sleeping, and mood. Although many therapeutic modalities have been tried in CRPS type I, given the debilitating nature of the disorder and the variable response to therapy, new and alternative therapeutic interventions, such as continuous peripheral nerve catheters, are needed.
