Tick paralysis is caused by a neurotoxin secreted by female tick. Characteristic initial manifestation is bilateral flaccid ascending paralysis similar to Guillain-Barr? syndrome. The predominant electrophysiological abnormality is a reduction in complex muscle action potentials. Here, we present a 62-year-old man who initially experienced a sudden biting pain on his scalp. Subsequently he developed bilateral lower extremity paralysis that ascended symmetrically involving the upper extremities. Within 2 weeks, the patient showed a full recovery without treatment.

PURPOSE: This study was done to evaluate xerostomia following intensity modulated radiotherapy for patients with head and neck cancer, and to analyze the correlation between the dosimetric parameters and xerostomia parameters. MATERIALS AND MEHTODS: From February till October 2003, 13 patients with 3 months of follow-up were evaluated for xerostomia after being treated for head and neck cancer with IMRT. Their median age was 57 years (range: 43~77). Xerostomia were assessed with a 4-question xerostomia questionnaire score (XQS) and a test for salivary flow rates (unstimulated and stimulated). The patients were also given a validated LENT SOMA scale (LSC) questionnaire. The evaluations were completed before radiation therapy (pre-RT) and at 1 and, 3 months after radiation therapy (RT). We evaluated xerostomia at pre-RT, 1 and, 3 months after RT. The association between the xerostomia parameters (XQS and LSC) and salivary flow rates (unstimulated and stimulated: USFR and SSFR) was assessed at 1 and 3 months after RT. RESULTS: All 13 patients showed no significant changes in XQS, LSC and Salivary Flow rates. As a result, we couldn`t find out about xerostomia development. Based on the total mean parotid dose, 3,500 cGy, we divided these patients into two groups. The 8 patients (<3,500 cGy) showed no significant changes in XQS, LSC and Salivary Flow rates. However, in 5 patients (> or =3,500 cGy), there was a significant increase in USFR and, SSFR at 3 months after RT, and for the XQS and, LSC at 1 and 3 months after RT. The correlation between XQS and, LSC, and USFR and, SSFR in all patients (13) was significant at 3 months after RT. The correlation had a tendency to the decrease for USFR and, SSFR in proportion to the increase of XQS and, LSC. CONCLUSION: Based on the results of this study, IMRT seem to be an effective treatment to significantly decrease the xerostomia. XQS and, LSC seem to be a effective tool for predicting the xerostomia. A total parotid gland mean dose of <3,500 cGy should be a planning goal if substantial sparing of the gland function is desired. Furthermore, patients should be enrolled in a study to define a more accurate threshold dose for the parotid gland.

PURPOSE: We determine the Korean antibody titer and positive rate of tetanus by using a with qualitative test (ELISA) and a quantitative test (TQS(R)). METHODS: This study was prospective collecting study with uncontolled patients who were admitted in 21 Emergency Departments during 3 months in South Korea. We measured TQS(R) and collected the serum with a centrifuge for 5 groups, which was classified with age: 2~10 years (I), 11~20 years (II), 21~30 years (III), 31~40 years (IV), 41~60 years (V), in each hospital. The freezed serum and the protocol with TQS(R) results were taken at the Soonchunhyang University Bucheon hospital to be analyzed. RESULTS: The number of enrolled patients was 1816 (male 58%). The positive rate of TQS(R) was 835 patients (46%), and there was no relation with region or sex. In sex and age, there was a definitive decline in the group III fort males and females. The results of ELISA was showed that 62.8% (> 0.15 IU/ml) and 52.2% (> 0.2 IU/ml) had protective levels of tetanus antibody. The proportion decreased to approximately 43% and 18% among persons 40~60 years of age at each level of antibody titers. By region and population, there was no statistical relationship with TQS(R) and ELISA, but previous military service was associated with a higher prevalence of protective antibodies to tetanus (p<0.001). CONCLUSIONS: A substantial portion of adults in South Korea do not have antibody levels that are protective against tetanus. Also, the mean level of tetanus antibody titers was definitively lower than those of other developed conturies and consistently decreased with aging. Therefore, an adult formulation diphteria and tetanus toxoid every 5 or 10 years is recommended for all adults between 20 and 60 years of age after being tested with TQS(R) in South Korea.
