In 1989, the Bethesda System (TBS) was introduced as an attempt to standardize cervical/vaginal reporting systems. TBS nomenclature was created for reporting cytologic diagnoses to replace the currently used Cervical Intraepithelial Neoplasia (CIN) and Papanicolaou Class System, which are deemed less reproducible. The name for preinvasive squamous lesions was changed to squamous intraepithelial lesion (SIL), subdivided into low-grade and high-grade types. TBS recommends a specific format for cytologic report, starting with explicit statement on the adequacy of the specimen, followed by general categorization and descriptive diagnosis. Pathologic and epidemiologic studies performed over last 10 years have provided evidence that human papillomavirus (HPV) plays a significant role in the development of cervical neoplasia. TBS corresponds not only to currently held views of the behavior of preinvasive lesions and their HPV distribution, but also to the current guidelines for clinical management.

Supernumerary isochromosome resulting in autosomal tetrasomy are rare and have been described only for 12P, 18P, and 9P. Tetrasomy 9P, initially described by Ghymer et al, is a rare chromosomal aberration that has been described in 20 patients. Affected subjects show both cytogenetic and ohenotypic variability. Some patients have the abnormal cell line in all cells, but many display tissue limited mosaicism. The phenotype varies in severity from prenatal death to mild developmental delay and minor anomalies. We reported a infant with mild manifestations of tetrasomy 9p with brief review of related literatures.

PURPOSE: Rotavirus infection is a leading cause of severe gastroenteritis among infants and young children worldwide. In temperate regions, institutional outbreaks of the disease occur mainly in cold dry weather, whereas in tropical settings its seasonal course is less well defined. We studied the annual changes in the seasonal prevalence of rotavirus infection for 5 years. METHODS: The study was conducted on 502 patients who lived in Taejon city and its vicinity. They were diagnosed with rotavirus gastroenteritis by stool latex coagulation method in Eulji Medical College Hospital from July 1993 to June 1998. RESULTS: During the 5-years period, 502 fecal specimens were positive by rotavirus latex coagulation method. The peak of the infection occurred in 1994 (July 1994-June 1995), 152 cases (30.3%) from July 1994 to June 1995 and the next peak occurred in 111 cases (22.1%) from July 1993 to June 1994. The seasonal peaks of the infection occurred in December 1993 (17.1%) and January 1994 (21.1%) and in March 1996 (23.4%) and March 1997 (22.5%). CONCLUSOIN: We observed that the seasonal peak in rotavirus infection changed over a 5-year period. The timing of rotavirus activity peaked during December-January(1993 and 1994), Februray-March (1996), and March-April (1997).

Favre-Racouchot syndrome is a disease of senile or actinic processes and another name is nodular elastosis with cysts and comedones. Clinically, facial skin shows, especially lateral to the eyes, multiple open and cystically dilatated comedones and can be defined as cutaneous disturbances characterized by a degenerative process of the dermis associated with cysts and comedones. Sunlight is a strong causative factor and dermal degenerative processes result in this condition. We report the case of a 78-year-old man who showed multiple yellowish papules on both sides of cheeks, the periorbital and, malar areas. He had had this condition for 25-years. His job used to involve physical labor and much exposure to sunlight. An excisional biopsy specimen from the facial malar lesion showed cystically dilated comedones with basophilically degenerated dermal tissue. We performed a therapeutic excision on the two large nodular lesions on both malar areas and applied topical tretinoin. The Patients clinical appearance was much improved 2 months later.

BACKGROUND: The recent studies shows that LV relaxation abnormalities are the important factors of heart failure in elders. To determine the association between LV diastolic functions and heart failure, we assessed LV diastolic functions in elderly patients with pulmonary congestion and in asymptomatic elders by using pulsed doppler echocardiography. METHODS: In order to assess LV diastolic function, we performed pulsed doppler echocardiography to elderly patients with pulmonary congestion and asymptomatic elders from Mar.2001 to Sep.2001. The following parameters were used as indices of LV diastolic function; Mitral E wave(E), Mitral A wave(A), Deceleration time(DT), Isovolumic relaxation time(IVRT), Systolic pulmonary venous flow(PVs), Diastolic pulmonary venous flow(PVd). RESULTS: In elderly patients groups, there was significant increase in deceleration time compared with asymptomatic elders(255.83+/-54.41 vs 210.80+/-48.53, p<0.05). There was significant increase in isovolumic relaxation time in elderly patient group compared with asymptomatic elders(123.06+/-25.07 vs 98.78+/-15.12, p<0.01). Although there was no significant difference, decreased E/A ratio and increased PVs/PVd were noted in both groups. CONCLUSIONS: The results shows that the impairments of LV diastolic function were noted in both groups. Especially DT and JVRT were significant increase in elderly patient group with pulmonary congestion. Therefore these parameters, such as DT, IVRT, can be helpful as predictive indices of diastolic heart failure in elders.

Choroid plexus papilloma(CPP) is a rare intraventricular neoplasm occurring primarily in the lateral ventricle of children and the 4th ventricle of adults. The 3rd ventricle is an extremely rare site for CPP to occur. The authors report two cases of CPP of the 3rd ventricle in a 2-month-old girl and a 4-month-old boy, and one case of CPP of the 4th ventricle in a 17-year-old male. Two CPP of third ventricle were totally removed by transcortical-transventricular approach and transcallosal subchoroidal approach, respectively. The CPP in the fourth ventricle was totally removed by suboccipital approach. The subdural hygroma and hydrocephalus due to CSF overproduction was managed with subduroperitoneal shunt and ventriculoperitoneal shunt.

Bowen's disease is a squamous cell carcinoma in situ and has the potential to progress to a squamous cell carcinoma. The authors treated two female patients (a 39-year-old and a 41-year-old) with Bowen's disease in the vulva area using topical photodynamic therapy (PDT), involving the use of 5-aminolaevulinic acid and a light-emitting diode device. The light was administered at an intensity of 80 mW/cm2 for a dose of 120 J/cm2 biweekly for 6 cycles. The 39-year-old patient showed excellent clinical improvement, but the other patient achieved only a partial response. Even though one patient underwent a total excision 1 year later due to recurrence, both patients were satisfied with the cosmetic outcomes of this therapy and the partial improvement over time. The common side effect of PDT was a stinging sensation. PDT provides a relatively effective and useful alternative treatment for Bowen's disease in the vulva area.

PURPOSE: The purpose of this study was to compare the diagnostic efficacy of mammography, Ultrasonography(US) and T-scan in pathologically confirmed breast diseases. MATERIALS AND METHODS: Thirty-eight patients withpathologically confirmed breast diseases who had undergone T-scan and mammography and/or US were retrospectivelyreviewed. Cases were categorized as normal, benign, or malignant, and on the basis of disease entity and masssize, the results were compared with pathologic diagnosis. For the of t scans, the conductance ratio was alsoused. RESULTS: Twenty cases were benign and 18 were malignant. The sensitivity, specificity and positivepredictive value of mammography were 100%, 70%, 74%;respectively. For US, the corresponding figures were 100%,82%, 88%, and for T-scan, 33%, 85%, 67%. Between masses with a diameter of less than 2cm and more than 2cm, thesensitivity, specificity, and positive predictive value of mammography and US demonstrated no significantdifference, except in some cases ; for T-scan however, the respective results were 10%, 80%, 33% when lesion sizewas less than 2cm, and 56%, 90%, 83% when lesions were larger than 2cm. The diagnostic efficacy of T-scan was thusgreater for larger lesions than for smaller ones. With regard to the conductance ratio of T-scan no pathologicallymalignant lesions showed high suspicion of malignancy but 33% showed moderate suspicion. CONCLUSION: Mammographyand US were useful in diagnosing breast malignancy. T-scan was less efficient for the diagnosis of breastmalignancies smaller than 2cm, and of infiltrating ductal carcinoma and ductal carcinoma in situ. They may thus beconsidered a complementary to mammography and ultrasound examination.

In order to find out possible causes and measures for prevention of intracerebral hemorrhage remote from the site of cerebral aneurysm surgery, the authors analyzed five patients who developed such a complication following aneurysm surgery among 720 surgical cases of cerebral aneurysm. The aneurysm sites were posterior communicating artery(Pcom) in two cases, anterior communicating artery(Acom) in two, and Acom and middle cerebral artery(MMCA) in one. The hemorrhages in three cases occurred in the cerebellum. One in the contralateral hemisphere and one in the ipsilateral hemisphere to the operation site. All hemorrhages except one occurred vasospasm preoperatively. Fluctuation of blood pressure with sudden elevation to high level was noticed in three cases preoperatively and in all cases postoperatively. We conclude that sudden elevation of blood pressure during the remission stage of vasospasm seems to be possible cause for remote hemorrhage. To prevent this complication, we recommend meticulous control of blood pressure during surgery and in the postoperative period, especially in cases that showed fluctuation of blood pressure preoperatively.
