BACKGROUND: The peripheral blood hemoglobin and serum ferritin were analyzed in 30 consecutive repeat blood donors (28 men, 2 women; mean +/- SD age: 28.0 +/- 8.6 years: median number of donation 12.9 +/- 9.5) to evaluate the influence of the whole blood donation. 16 beginners in the blood donation were used for normal control (12 men, 4 women; 27.5 +/- 7.5years). METHOD: The repeat donors were grouped into the interval and frequency of donation. At the time of donation, blood samples were collected from all for research. Hemograms were performed using an automatic cell counter and enzyme immunoassay were used for the serum ferritin determination. Total protein and albumin were determined with an autoanalyzer. RESLUTS: The levels of the peripheral blood hemoglobin of the repeat donors were within normal limits and the median level was not significantly differentiated between the tested groups and normal control group. The median level of serum ferritin of the repeat donors was 32.19 +/- 22.82ng/mL, which was significantly low compared to the level of the normal control (62.10 +/- 25.67ng/mL, n=16)and was correlated with the interval and frequency of donation. The donors having short intervals less than 4 month reveal low ferritin level compared to other tested groups even though it was not significant. However the frequency of donation influenced significantly the level of serum ferritin. The median level of serum ferritin of the W/B donors having frequency of donation more often than 5 times was 30.64 +/- 16.22ng/mL, significantly lower than that of other tested groups and normal control (P<0.05). CONCLUSION: The Interval and frequency of blood donation seem to be very important factors that act upon nutiritional status of consecutive repeat donors. Especially consecutive, frequent donation of W/B must be deplet the storage iron in the body. Therefore the interval and frequency of donation must be adjustified and must be permitted in proper manner for korean blood donors. Test items such as hemoglobin and serum ferritin seem to be essential for repeat donors at the time of donation. Also if we can, oral iron supplement could be recommended for the repeat donors in proper time to prevent iron depletion.

Background: Radiation therapy (RT) is frequently used for supportive treatment and management of advanced head and neck cancers. This study performed a retrospective review of the treatment methods that were used for intractable draining fistulas in seven patients who had received RT for head and neck cancers. Treatment methods used for two of the seven patients are presented in detail. Methods From 2009 to 2020, seven patients underwent reconstructive surgery for intractable fistulas which occurred after RT for head and neck cancers. Patient characteristics, medical history, treatment method, and treatment outcome were reviewed for each case. The type of surgery performed, failure rate, and treatment period were also analyzed. Results: In this study, a total of seven patients received additional management for radiation-induced fistulas. Patients underwent a mean of 3.3± 1.4 surgeries (maximum: six surgeries) to resolve their fistulas. The mean time interval from the first surgery to the last surgery for the patients to achieve resolution of the fistula was 8.7 months. Loco-regional flaps have performed an average of 1.9± 1.5 times. However, all loco-regional flaps failed. Instead, the patients’ intractable fistulas were resolved with the use of distant flaps or free tissue transfers. Conclusion: Fistulas that develop after head and neck cancer treatment following RT are difficult to treat with simple loco-regional flap procedures. Therefore, more aggressive treatment techniques, such as distant flap or free tissue transfer, may be needed to shorten patients’ treatment periods and avoid unnecessary surgeries.

BACKGROUND: Hepatitis viral markers and ALT levels were evaluated in 190,679 blood donors to infer correlation between positive and control groups. The positive rate of anti-HBc was also observed in HBsAg and anti-HBs negative donors to know necessity about adding the item to the donor screening test. METHODS: The viral markers were tested by EIA method and ALT test was carried by auto-chemistry analyzer. Anti-HCV ELISA positive samples were confirmed by immunoblot assay. RESULTS: The rate of HBsAg(+) was 3.01% and that of anti-HCV was 0.54% of blood donors. The rate of HBsAg(+) and anti-HCV(+) was 0.01% of blood donors. Average ALT level of anti-HCV(+) (immunoblot assay) group was significantly higher than that of the control group. (p<0.001). The positive rate of anti-HCV in confirmatory test (immunoblot assay) was 15.76%. The proportion of donors who were HBsAg(-) and anti-HBs(-) and anti-HBc(+) was 1.87% in 1500 blood donors. CONCLUSION: The average ALT levels seem to be not correlated with viral hepatitis marker positivity except anti-HCV immunoblot assay positivity. It is suggested that anti-HBc and anti-HBs test should be added to screening test for donors and recipients to prevent post transfusional hepatitis.
