BACKGROUND: Disinfection is essential for the prevention of hospital infoction. Tego-51, one of the amphoteric surfactants based on the dodecyl-di( aminoethyl)-glycine, has been considered as an effctive disinfectant having a broad specturn of antimicrobial activity. We evaluated the disinfective activity of Tego-51 against several clinical isolates of bacteria and yeasts including Helicobacter pyiori. METHODS: Twenty three strains of vacteria including H. pylori, and a strain of yeast were exposed to the various concentrations (0.05%, 0.01%, 0.005%) of Tego-51 for the various periods (0.5, 1, 2, 4, 8, 16min). After the exposure to Tego-51 disinfectant, 0.01 mL of mixture of microorfanisms and Tego-51 was inoculated into brain-heart infusion broth, into Sabouraud dextrose agar. or Wilkins-Chalgren agar with 10% sheep blood, and incubated at 37 degrees C for 48 hours or in the Campy Pouch microaerophilic system. RESULTS: Most strains were killed within 30 seconds after an exposure to 0.01% of Tego-51, but Proteus mirabilis was eradicated after two minutes of exposure. At the concentration of 0.005 % concentration. P. mirabilis and Bacillus subtilis were killed after eight minutes od exposure. H. pylori was killed with 0.005% Tego-51within 30 seconds. Conslusions: This study showed that Tego-51disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital. It may be recommended that Tego-51 should be used at concentration greater than 0.1% for the effective disinfection of skin, instruments and hospital floors.

PURPOSE: To evaluate the prevalence of the opacification of paranasal sinuses and to correlate the prevalence and severity of the sinus opacification with presence of upper respiratory infection (URI) in infants and children using CT. MATERIALS & METHODS: We analyzed CT scans of 162 children aged under 16 who have no signs and symptoms of paranasal sinusitis. Both sides of maxillary and ethmoidal sinuses were evaluated. We scored from 0 to 3 according to the degree of soft tissue opacification of each sinus and then summed up the scores of each sinus. We divided the children into 5 groups according to their age. We paid particular attention to the following respects: 1) the prevalence of the opacification of the paranasal sinuses in each group; 2) the difference in the prevalence between the children with and without URI ;3) the correlation between the severity of the sinus opacification and the presence of URI. RESULTS: Of 162 children, one or more paranasal sinus opacification was noted in 76(47 %):31(65%) less than 1 year old;11(52%) between 1 and 2 years old;16(53%) between 2 and 6 years old ;15(28%) between 6 and 12 years old;and 3(33%) above 12 years old. In children less than 1 year old, no significant difference in the prevalence of the sinus opacification was found between URI-positive(71%) and URI-negative(58%) subgroups. In chilren between 1 and 12 years old, although the prevalence of the sinus opacification in URI-positive subgroups was much greater than that in URI-negative subgroup, statistically significant difference was noted only in children between 2 and 6 years old. As to the correlation between the severity of the sinus opacification and the presence of URI, these was a statistically significant difference in children between 2 and 6 years old and between 6 and 12 years old. CONCLUSION: Although the exact pathophysiology is not fully understood, the opacification of the paranasal sinuses is not an uncommon finding at CT in children without the signs and symptoms of sinusitis. We think that the clinical correlation is essential in determining the diagnosis and treatment plan in cases that the sinus radiographs or CT scans show the abnormal findings.

BACKGROUND: Since the first introduction of radioimmunoassay for the quantification of the thyroidstimulating hormone (TSH), more advanced analytical methods have been developed and used in laboratories. However, they are still inconvenient in that they require time-consuming procedures, special safety in handling isotopes, expensive equipment, and a highly qualified expert. METHODS: As an immunoassay system for the rapid measurement of TSH in serum, we have developed a new analytical system based on immunochromatographic assay with fluorescencelabeled anti-TSH monoclonal antibodies. The assay system is composed of a test strip housed within a cartridge and a laser-fluorescence scanner for quantification. The strip contains a sample pad, an absorption pad, and a nitrocellulose membrane where a captured antibody is immobilized and antigen-antibody reaction occurs. Fifty microL of serum was added to 50 microL of a detector solution and the mixture was loaded onto the well of the sample pad on the cartridge. After incubation for 12 min, the cartridge was quantified with the laser-fluorescence scanner. RESULTS: The calibration curve displayed linearity (R=0.95) at concentrations of 1-40 mIU/L. Intraand inter-assay imprecisions were determined to be CVs within 10%. Analytical recovery was 93.9% at 3 different concentrations and the detection limit was 0.868 mIU/L of TSH. The new assay system correlated well with an Abbott AxSYM for quantification of TSH (R=0.97, slope 0.94, N=20). CONCLUSIONS: The TSH measurement system developed in this study showed good reproducibility. However, our TSH quantification system needs some improvement to be used in the medical field because of its low analytical sensitivity. With enhanced performance in analytical sensitivity, introduction of a whole-blood type strip, and a more miniaturized fluorescence scanner, we expect the TSH analytical system to be used for point-of-care testing in the near future.

Malignant tumors of the maxilla represent about 3-4% of head and neck malignant neoplasm and the origins are maxillary gingiva, hard palate and maxillary sinus. We are to investigate clinical features and results according to various treatment modalities of maxillary malignant tumor to get information for better treatment results. Sixty patients with malignant maxillary tumors treated at Yonsei medical center from 1992 to 1997 were studied retrospectively. They are evaluated according to clinical signs & symptoms, stages at first diagnosis, primary site, histopathologic features, treatment method, recurrence and survival rate with clinical records, biopsy results and CT radiograph. The most common primary site was maxillary sinus and most common histopathology was squamous cell carcinoma. The local recurrence rate was 18% at 5 years, neck failure was 3% and distant metastasis was 18%. Overall survival rate was 78% at 2 years and 69% at 5 years. Failure at primary site is the main problem in the curative treatment. So, to improve survival in these patients efforts should be directed toward improvement of local control.

Caliceal diverticula are eventrations of the upper collecting system lying within the renal parenchyma and communicating with renal pelvis or a calyx through a narrow channel. The incidence on a routine IVP is approximately 0.21 to 0.45 percent and stone formation in a caliceal diverticulum has arised from 9.5 to 50 percent. Traditionally, treatment has included nephrotomy with extraction of the calculi and percutaneous nephrolithotripsy, but more recently ESWL has been challenged due to less invasive and safer procedure. We report the results of 11 patients with calculi in caliceal diverticula treated with EDAP LT-01 lithotriptor. All patients were followed during 2-11 months (average in 6.6) The results were obtained as follows ; 1. The symptoms were included chronic vague flank pain in seven, acute renal colic in two, epigastric discomfort in one and incidentally diagnosed in one. 2. The location of diverticula were upper third in seven, mid third in three and lower third of kidney in one. The stone size showed under 10mm in seven, 11-20mm in three and over 21mm in one. 3. The average numbers of treatment were 2.2 sessions and average storage was 102. 4. The complete success rate in 63.6 % (stone free rate in 45.5 %) and partial success rate in 27.2% were showed. 5. The complete relief of symptom was in eight (72.7% ), partial in one (9.1%) and persistent symptom in two (18.2 9t ). 6. Complication was showed only gross hematuria for 1 day in 63.6 %, but all patients recovered with conservative treatment. Therefore, the possibility of producing a satisfactory result (relief of symptom in 81.1%) and the low morbidity of ESWL suggest that this treatment may be appropriate for calculi in caliceal diverticuli.

Extramammary Pagets disease of the vulva is an uncommon vulvar neoplasm with a high rate of recurrence. We report a young woman in whom vulval Paget's disease occurred in association with local adenocarcinoma. The patient presented at the age of 28 years with slowly growing vulval mass which had some mucoid discharge. Biopsy of the mass showed Paget's disease with associated local adenocarcinoma. This patient received modified radical vulvectomy with unilateral inguinofemoral lymphadenectomy. Until now she is under follow up without evidence of recurrence for 24 months. According to our medline research from 1980 to 2000, this case is the youngest asian patient yet recorded. We recommend that abnormally growing vulvar mass need to be biopsied eventhough she is young.

Winkelmann granuloma is a very rare disorder characterized by histologic findings of perhaps[ic] infiltration, collagen degeneration, and granulomatous inflammation, which usually show palisading features. A number of diseases, especially systemic immunoreactive diseases, are associated with this disorder. We describe a focal neutrophilic necrosis : type of Winkelmann granuloma associated with hypothy- roidism and rheumatoid arthritis.

ESWL is clearly an effective noninvasive treatment for a wide variety of urinary tract calculi. However, numerous clinical and experimental reports present evidence that ESWL can cause acute and chronic complications, especially new onset hypertension. We evaluated that relationship between hypertension and plasma renin activity with follow-up of 1 month after one session ESWL and round that 3.1% of patient showed new onset hypertension. The plasma renin activity was slightly elevated 24 hours after ESWL, but by 1 month after procedure the renin had decreased to near pre-ESWL level. However. these data represented no statistically significant change (p>0.05). Therefore, we believed that at the moment no relation between plasma renin activity and hypertension at least early period of post-ESWL (1 month).
