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.

PURPOSE: Fine needle aspiration is a safe and relatively accurate procedure for distinguishing benign and malignant lesions. We determined the diagnostic value of ultrasoundguided fine needle aspiration using an extension tube and examination by an endocrine surgeon. METHODS: We reviewed the medical records of 257 consecutive patients receiving surgery for thyroid nodules in the Department of Surgery, Jesus Hospital, from January, 2006, to August, 2008. All patients received ultrasound-guided fine needle aspiration with an extension tube. RESULTS: The male to female ratio was 1:5.5. Definitive histopathological diagnosis revealed benign lesions in 120 cases (47%) and malignant lesions in 137 cases (53%). Benign lesions were composed of nodular goiter (102 cases), follicular adenoma (13 cases), and Hashimoto thyroiditis (5 cases). Malignant lesions were composed of papillary carcinoma (131 cases) and follicular carcinoma (6 cases). Fine needle aspiration cytology revealed benign lesions in 103 cases and malignant lesions in 126 cases. The Overall results of ultrasound-guided FNA were: sensitivity, 94.5%, specificity, 95.0%, positive predictive value, 96.0%, negative predictive value, 93.2%, accuracy rate, 94.7%, false negative, 5.4%, and false positive, 4.9%. Most specimens (96.4%) were amenable for diagnosis. CONCLUSION: Fine needle aspiration is a good method for the differential diagnosis of thyroid nodules. High resolution ultrasound-guided FNA with an extension tube is helpful for obtaining good specimens.
