Five years ago, we made the cut-off value of Tsh by dry filter paper method as 15 microU/ml to sereening congenital hypothyroidism. Since then, 1,210 term neonates, who had no perinatal problems, were born in SNUCH between Aug. 1987 and Apr. 1992, had been performed this neonatal Tsh screening test with this cut-off point. Neonates had been recalled for measurement of serum T4/TSH to rule out congenital hypoothyroidism if their TSH value by screening tests reveal more than 15 microU/ml. Because there had been high false-positive rate during 5 years, we felt thiscut-off value of TSH should be set higher than 15 microU/ml with same method. Therefore, we analyzedthis TSH values to set a new cut-off point to recall the neonates. The results ars asbelow: 1) TSH value by dry filter paper method was 8.48+/-4.41 U/ml(mean+/-S.D.) 2) Assuming 15 microU/ml as a cut-off point for recall the neonates, the false positive fate is 8.01% 3) Tomake the false positive rates as 0.3%, it is reasonable to set the cut-off point at 22 microU/ml, whichis +/-3S.D.(99.7 percentile) of measured TSH level by dry filter paper method.

Benign paroxysmal positional vertigo (BPPV) is characterized by episodic vertigo and nystagmus provoked by head motions. To study the characteristics of BPPV in a large group of patients in Korea, we retrospectively analyzed clinical features of 1,692 patients (women: 1,146, 67.7%; men: 54.6, 32.3%; mean age: 54.8+/-14.0 yr), who had been diagnosed as BPPV by trained neuro-otologists Dizziness Clinics. The diagnosis of BPPV was based on typical nystagmus elicited by positioning maneuvers. Posterior semicircular canal was involved in 60.9% of the patients, horizontal canal in 31.9%, anterior canal in 2.2%, and mixed canals in 5.0%. The horizontal canal type of BPPV (HC-BPPV) comprised 49.5% of geotropic and 50.5% of apogeotropic types. We could observe significant negative correlation between the proportion of HC-BPPV of each clinic and the mean time interval between the symptom onset and the first visit to the clinics (r=-0.841, p<0.05). Most patients were successfully treated with canalith repositioning maneuvers (86.9%). The high incidence of HC-BPPV in this study may be explained by relatively shorter time interval between the symptom onset and visit to the Dizziness Clinics in Korea, compared with previous studies in other countries.

Although most persons infected with Helicobacter pylori harbor a single strain of the organism, multiple strain colonization in the same patient is also occasionally reported in developed countries. The aims of this study were to determine the prevalence of multiple strain colonization in Korean patients and to detect the cagA, iceA1, and babA status of H. pylori isolated from the antrum and body of the stomach. H. pylori was obtained from 35 patients from the antrum and body of the stomach. The genomic diversity of H. pylori was determined by random amplified polymorphic DNA analysis. The status of cagA, iceA1, and babA genes of H. pylori was assessed by polymerase chain reaction with appropriate primers. Clearly different diversity patterns were identified among the isolates from 35 individual patients. Eighteen (51.4%) patients had a single strain of H. pylori. Eight (22.9%) and nine (25.7%) patients had subtypically (one or two bands difference) and typically (clearly different pattern) different strains of H. pylori in the antrum and body, respectively. Among the 70 isolates of H. pylori from 35 patients, the positive rates of 349-bp and 208-bp cagA gene fragments and the iceA1 gene were 68/70 (97.1%), 68/70 (97.1%), and 58/70 (82.9%), respectively. However, the babA gene was found in 22/66 cases (31.4%). In five out of 18 patients with a single strain, the genetic status of cagA, iceA1, and babA varied between the isolates from the antrum and the body. In 8/17 patients with subtypically or typically different strains, the gene status differed between antrum and body isolates. The prevalence of co-colonization with typically or subtypically different strains is high in Korea, and sub-clones with different pathogenic gene status exist within strains of identical RAPD patterns.

OBJECTIVE: To figure out the more optimal method for freezing and thawing the sperm, we compared with the sperm motility after handling of the sperm based on the different types of freezing and thawing methods. METHODS:Twenty four adult males who visited our infertility clinic from Aug 2004 to Feb 2005 were enrolled. We applied two kinds of freezing method to normal sperm according to WHO standard criteria; automatic slow freezing method (Auto) and manual vapor freezing method (Manu). We also use two different methods of thawing; a 37 degreesC warm water bath (37 degreesC) and 22 degreesC room temperature thawing (22 degreesC). Mean motile percent (MMP) was compared by the freezing methods and thawing methods respectively. We also evaluated the motility in four different ways of freezing and thawing combination. A written informed consent was obtained from each client. This study was approved by IRB. RESULTS: MMP by the freezing method was 56% in Auto group and 52% in Manu group. It was significantly different (P=0.037). In thawing method, it was 59% in 37 degreesC group and 49% in 22 degreesC group (P=0.000). Each of freezing and thawing methods was joined to make four different types of freezing and thawing combinations. In MMP there were 63% in Auto/37 degreesC, 50% in Auto/22 degreesC, 56% in Manu/37 degreesC and 48% in Manu/22 degreesC (P>0.05). CONCLUSION: The automatic method in freezing and room temperature in thawing showed respectively the highest MMP. In four different types of freezing and thawing combinations, Auto/37 degreesC MMP was the highest. There was no statistical difference. This means that all four types of freezing and thawing methods might be used clinically. If further study of larger population or comparison of fertility is done, we would have a better result.

Pelvic actinomycosis is a chronic, progressive, granulomatous and suppurative disease caused by an anaerobic or microaerobic Gram-positive organism, not fungi. Actinomyces species exhibit branching, filamentous growth and appear in the human skin, oral cavity, gastrointestinal tract. Actinomyces infection in human is relatively rare, however, prolonged use of an intrauterine contraceptive device (IUD) is a well known risk factor of pelvic actinomycosis. Pelvic actinomycosis can mimick pelvic malignancy leading to mutilating surgical excision, and diagnostic problems necessitated a laparotomy in many patients. The pathohistological diagnosis is based on the characteristic microscopic image and specific staining of sulfur granule. Adequate surgical excision and administration of antibiotics show good prognosis. We experienced 2 cases of pelvic actinomycosis with the intestinal obstruction, confirmed patho- histologically after laparotomy.
