Waardenburg syndrome is a very rare auditory-pigment syndrome with autosomal dominant inheritance. In his first report in 1951, Waardenburg characterized this syndrome as dystopia canthorum, a high broad nasal bridge, synophrys[confluent eyebrows], heterochromia iridid, a white forelock or early graying, and sensory neural deafness. We observed a case of Type 2 Waardenburg syndrome with openangle glaucoma and, therefore report with literature review.

The advent of the global pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) necessitates a thorough study of the stability and transmissibility in the environment. We characterized the stability of SARS-CoV-2 in three water matrices: fresh, tap, and seawater. The minimum infective dose of SARS-CoV-2 in Vero cells was confirmed to be 10 3 PFU/mL. The stability of SARS-CoV-2 varied according to the water matrix: infective SARSCoV-2 was undetectable after treatment with fresh water and seawater, but remained detectable for 2 days in tap water, when starting with an initial concentration of 10 4 PFU/mL. When the starting concentration was increased to 10 5 PFU/mL, a similar trend was observed. In addition, viral RNA persisted longer than infectious virus in all water matrices. This study was conducted in stagnant water containing a significantly high titer of virus, thus, human-to-human transmission of SARS-CoV-2 through the actual aquatic environment is expected to be rare.

It is well known that the cell type and histopathological grading of gliomas correlate well with clinicalcourse and prognosis. Therefore, it is tempting to set certain criteria that could predict the histopathologiccharacteristics of the gliomas before the surgical intervention. With a total of 56 cases of gliomas which wereverified histopathologically in Seoul National University Hospital between July 1978 and May 1983, a statisticalanalysis of the computed tomographic findings was done with the particular emphasis on the correlation withhistopatholoigcal features. The results are as follows; 1. The calcification is observed in 27 cases (48.2%) intotal: in 20 cases (62.5%) among low grade group, in 6 cases (46.1%) among high grade group and in 1 case (9.1%)among glioblastoma multiformed group respectively. 2. The mass effect, especially surrounding low densitycorrelates well with the grade of malignancy. 3. The contrast enhancement is observed in 43 cases (76.8%). Thepattern of enhancement provides clues for the assessment of cell type and grade with fair degree of reliability.Among low grade group, 10 cases (31.3%) show no enhancement and 10 cases show solid enhancement. Among high gradegroup, 6 cases (46.8%) show solid enhancement and nodular or ring enhancement are not observed. Among glioblastomamlultiform group, 8 cases (72.7%) show characteristic thick irregular ring enhancement. 4. Plain CT densities arenot useful in differentiating each group in statistically significant level. 5. Neither the margin of the mass northe degree of contrast enhancement contributes for the differentiation of each group. 6. Summarizing the abovementioned findings it is concluded that CT is very helpful in differentiating the gliomas with regard tohistopathological cell type and the grade of malignancy as well.

A pathological study was done to elucidate sequential changes of the lungs in various time intervals following experimental paragonimiasis in 15 dogs and 15 cats. The dogs and cats were fed with 30-50 metacercariae of Paragonimus westermani, and were sacrificed at 15, 20, 30, 45, 60, 90 and 120 days after infection respecively. Autopsies were performed immediately after death. Gross and microscopic examination of the lungs showed following findings: There were no qualitative difference in pathological findings between dogs and cats. Pathological findings were first noticed at 20 days of infection in thoracic cavity, which consisted of fibrinous plueritis along with superficial hemorrhage. Although no worm was found in the lung parenchyma at this period, juveniles were seen in pleural cavity together with turbid effusion. Paragonimus juveniles were first recognized inside the lung parenchyma by 30 days of infection. This was the period when the lungs showed multiple areas of hemorrhage and probably active penetration by smaller worms. Hemorrhagic bronchopneumonia was quite pronounced from this stage through 45 days of infection. Paragonimus worm cyst was essentially composed of fibrous scar and heavy inflammatory cellular infiltrate. The lining epithelial cells were first became noticed by 2 months of infection. And these epithelial cells were thought to be probably transformed alveolar lining cells rather than bronchiolar epithelial cells. As the infection progress, the cyst wall became more stabilized and often showed squamous metaplasia. Fibrinous pleuritis with pleural effusion was very prominent finding in early periods of infection. Bronchiolitis and focal vascular sclerosis were often seen in experimental paragonimiasis.

PURPOSE: The purpose of this study was to construct and test a structural equation modeling on the reproductive health behavior of single women with sexual experiences. This study employed Ajzen's Theory of Planned Behavior (TPB). METHODS: The data were collected after receipt of consent from 250 single women with sexual experiences, and analyzed using SPSS 18.0 and AMOS 18.0. RESULTS: Model fit indices for the hypothetical model were suitable for the recommended level: x²=362.407, RMR=0.065, RMSEA=0.070, GFI=0.867. TLI=0.927, CFI=0.938, IFI=0.939, and x²/dF=2.237. Intention showed direct effect with the biggest effect being on reproductive health behavior. Attitude, subjective norm and perceived behavioral control were found to have a direct effect on intention. Among them, perceived behavioral control revealed the largest influence. CONCLUSION: This study suggests that the TPB is a suitable model in explaining the reproductive health behavior of single women with sexual experience. Strategic plans for educational and intervention programs should be aimed to encourage single women to engage in reproductive health behavior.
