3.Colony Formation Assay and Chemosensitivity Test for Urologic Malignancies: A Preliminary Report.
Korean Journal of Urology 1989;30(3):301-306
Use of the Hamburger-Salmon soft agar assay method for in vitro chemotherapy sensitivity testing was tried. In this assay, double soft agar was used to culture 9 human urologic tumors, including 2 renal adenocarcinomas, one Wilms' tumor, 4 bladder transitional cell carcinomas, one paratesticular rhabdomyosarcoma and one penile squamous cell carcinoma. Among these cancers, Wilms' tumor and penile carcinoma grew to the extent that they could be used in chemosensitivity testing in soft agar (> or =30 colonies per control plate). It is concluded from this study that in vitro chemosensitivity testing by colony formation assay may be a useful tool in the treatment of urologic cancers, but more experiences should be gathered.

BACKGROUND: For a rapid transfusion, pressure is sometimes applied to packed red blood cells during the operation. However, there are neither standard guidelines nor reported data regarding adequate change interval of transfusion kits. The aim of this study is to present relevant data by simulating a surgical situation. METHODS: Each unit of packed red blood cells was mixed with 50 mL of normal saline. Pressure (250 mmHg) was applied to the mixed red blood cells. Each filtration time was measured without change of the transfusion kit. The weight of the mixed red blood cells was measured before and after administration. The passed blood was examined microscopically for detection of possible microaggregation. Eight transfusion sets were tested with 70 packed red blood cells. RESULTS: International guidelines have recommended replacement of the transfusion set if flow rate decreased to less than 100 mL/min. The flow rate of five transfusion sets was recorded as less than 100 mL/min. The flow rate of the third packed red blood cells decreased to less than 100 mL/min. No microaggregate was detected. CONCLUSION: Therefore, we recommended replacement of the blood filter after filtering two units of packed red blood cells with pressure under operation room circumstances.

PURPOSE: The conventional surgical treatment for patients with potentially curable low rectal cancer is abdominoperineal resection. Recently there has been increasing interest in the use of preoperative radiation therapy and sphincter-saving procedure as primary therapy for selected low rectal cancers. We report our institutional experience with this approach. METHODS: From 1995 to 1997, Twelve patients with resectable distal rectal cancer were offered sphincter-saving procedure, excluding the patients whose pretreatment tumor presentation demonstrated fixation to anal sphincter or puborectalis muscle. The distance from the anal verge to the distal tumor margin at initial diagnosis ranged from 1 to 5 cm. Patients received a median 50.4 Gy and chemotherapy Surgery was carried out 4 to 8 weeks after radiation. RESULTS: No patient had toxic reaction that required interruption of chemoradiation. Four patients (33%) had complete pathologic response, but one patient with complete clinical response had residual cancer. Seven patients underwent hand-sewn coloanal anastomosis and five patients transanal excision en bloc. All patients were able to successfully undergo a sphincter-saving procedure. With a mean follow-up of 23 months (range, 6~32), the authors noted no recurrence or complication. Sphincter function was good in 92%. Daily bowel movements was two (range, 1~10). CONCLUSION: Preoperative chemoradiation appears promising in terms of better patient compliance, lesser toxicity, and downstaging tumor, making the sphincter-saving procedure feasible in carefully selected cases. Surgical resection remains essential to confirm and to achieve complete clinical remission. The results of preoperative chemoradiation and sphinctersaving procedure are encouraging, but more experience is needed to determine whether this approach ultimately has similar local control and survival rate compared to standard surgery.

A 2-month-old male patient visited with recurrent erythematous papules and pustules on face and neck that had developed 20 days after birth. Direct microscopic examination on smears for pustules showed forms of yeasts and culture yielded Malassezia sympodialis. Applying topical 2% ketoconazole cream for 15 days showed marked clinical improvement. We report this case of neonatal Malassezia pustulosis which be would probably improperly termed as neonatal acne with the review of literature.

One year field study of 400 lead workers on the effect of maintenance free respirator(MFR) to alleviate the lead burden revealed that MFR protection program with biological monitoring with simple measurement of zinc protoporphyrin in whole blood could be applied as an interim method to prevent lead workers from lead burden even in fairly bad working condition until fundamental environmental control will be taken in korea.
