The vitreous body is a gel-like structure occupying a space of about 4 cc posterior to the intraocular lens and provides an optically clear medium for light transmission. It has a complex physical and chemical composition and structure consists primarily of water, collagen, and hyaluronic acid. Floaters are tiny dark specks that can be seen in the visual field, especially when looking at the blue sky, a white wall, or any other uninterrupted, light colored expanse. They are created from tiny clumps in the clear, jelly-like substance inside the eyeball. Floaters occur in different sizes and shapes. They may appear as little dots, threads, or hairy clumps. Floating specks are most commonly caused by the posterior vitreous detachment due to thickening and shrinkage of the vitreous, frequently starting in middle ages but can also be caused by blood or inflammatory cells. In most cases, floaters are normal and harmless. However, a sudden increase in number may indicate a damage to certain internal structures of the eye. Any case with an acute onset of floaters or flashing lights should be carefully examined for the vitreoretinal condition. It should be borne in mind that the peripheral retina and vitreous can be visualized only in a dilated pupil, with careful examination using binocular indirect ophthalmoscopy or contact lens biomicroscopy.

We reported the case of Mr. M.H. Lee aged 46 years, who was first seen March. 4, 1972. The Chief complaint was pain on the left forehead and nausea for one day. Tension with the Schiotz tonometer was 45mmHg. The skin of left side of the forehead, inside of the eyebrow, left side of the radix nasi and nostril showed irregular papule formation in small circumscribed areas 2 days after admission. Acute iritis finding was occurred 6 days after the onset. The clinical course was one month. Sensitivity of the cornea was recovered and vision was improved to normal without posterior synechia or corneal ulcer.

Elderly adults are the demographic most likely to utilize emergency medical services (EMS). This study aimed to examine the difference in EMS utilization in subgroups of the elderly population by assessing the predictors for using EMS.

An in situ DNA hybridization technique was applied to detect human papillomavirus(HPV) DNA, HPV types 6/11 and 16/18, on paraffin sections of 36 cervical condylomatous lesions associated with cervical intraepithelial neoplasia and invasive squamous cell carcinoma. 1) HPV DNA sequences were identified in 14 of 36 cervical condylomatous lesions(39.0%); HPV 6/11 in 7 cases(19.0%) and HPV 16/18 in 7 cases(19.0%). 2) With the use of biotinylated HPV 6/11 DNA probes, 5 of 5 condyloma acuminata(100%), 1 of 5 flat condylomata(20%), and 1 of 7 mild dysplasias(14.3%) were positive. 3) With the use of HPV 16/18 DNA probes, 1 of 7 mild dysplasias(14.3%), 2 of 5 moderate dysplasias(40%), 2 of 4 severe dysplasias(50%), and 2 of 5 invasive squamous cell carcinomas(40%) were positive. 4) The positive stainings to HPV DNA probes were primarily detected in koilocytotic nuclei of the superficial epithelium. No positive signals were found in the normal, dysplastic or carcinoma cells. 5) The numbers positively stained cells were decreased with increasing severity of the lesions from benign condylomas to invasive squamous cell carcinomas. In conclusion, HPV types 6/11 were more commonly identified in benign condylomatous and low grade intraepithelial lesions than high grade lesions. However, HPV types 16/18 were identified in high grade CIN and invasive squamous cell carcinomas. The present results while supporting the concept on HPV 16/18 as the high risk of HPV types in cerivical carcinogenesis also emphasize the applicability of the situ DNA hybridization as a tool in analysis of the specific HPV DNA sequences in routine biopsies of these lesions.

Cholesteatoma in the kidney and ureter are accumulations of waxy, gray flakes of keratin materials, secondary to squamous metaplasia of the transitional epithelium. Herein, we describe a case of cholesteatoma in the renal pelvis of a 69-year-old woman, and give a brief review of the literature. In the upper pole of the left kidney was a 6 cm cystic lesion filled with a thick, flaky, grayish, comified material. Microscopically, the cystic area showed calyceal and pelvic structures being replaced by keratinizing stratified squamous epithelium. The surrounding renal parenchyma was atrophic with features of chronic pyelonephritis.

Adult Wilms' tumor, unlike that of childhood, is a rare disease. Microscopically, the tumor is fundamentally characterized by triplastic embryonal renal tumor composed of variable amounts of metanephric blastema and its epithelial and stromal derivatives but rarely a small group of tumors composed virtually entirely of differentiated epithelial derivatives, the abundance of tubular structures. These monomorphous epithelial type of Wilms' tumor tended to have an early onset and benign course. Grossly, classic Wilms' tumor is a solid tumor, but very rarely shows cystic change and may lead to misinterpretation as a polycystic kidney or multicystic nephroma. Here, we reports a case of primary renal tumor, grossly very similar to a multicystic kidney but histologically represent a tubular monomorphous epithelial variant of Wilms' tumor occured in 63 year old male adult.

As a part of fundamental studies for establishing appropriate electrocardiographic criteria of left ventricular hypertrophy for Koreans, 39 various criteria proposed by 25 authors were applied to 500 Koreans and the reliability of each criterion was analysed based upon cardiothoracic ratios in the chest teleroentgenograms. The subjects analysed in this study included cardiac and non-cardiac patients as well as healthy adults: in all of them electrocardiograms and chest roentgenograms were obtained on the same day. Both true and false positivities of the precordial voltage criteria were extremely high, whereas those of voltage criteria of the extremity leads and the remainder of various criteia were qutie low except for the point score system of Romhilt and Estes, which revealed relatively high true positivity and low false positivity. True positivities of all precordial voltage criteria were higher in males than in females. Their false positivities were also higher in males, except for criteria SV1>==24mm, RV1<==1mm and RV6>RV5, which were higher in females. No significant differences were noted between males and females, however, in the true and false positivities in the voltage criteria of the extremity leads. True and false positivities of the other criteria excluding various voltage criteria were also slightly higher in males than in females. In females, true positivities of the precordial voltage criteria were not closely related to the cardiothoracic ratios, whereas those of voltage criteria of the extremity leads and of the other criteria excluding voltage criteria were higher in those with greater cardiothoracic ratios. In males, however, true positivities of nearly all the criteria, including precordial voltage criteria, were higher in those with increased cardiothoracic ratios. In both males and females, criteria SV1>==24mm, RV1<==1mm, RV5>==33mm, RV6>RV5, RV6>==26mm, ventricular activation time(VAT) and left axis deviation(LAD) revealed low true and false positivities indicating that these criteria were of little practical values. In females, true positivitieies of criteria RaVF>==20mm or 21mm and VAT in V(5-6)>==0.66sec. were zero, indicating that these criteria were totally impractical. Both true and false positivities of almost all precordial voltage criteria were higher in Koreans than in Westerns but those of the voltage criteria of the extremity leads were similar in both groups. The remainder of the criteria revealed lower true positivities in Koreans than in Westerns but false positivities were similar in both groups. These facts denote that higher false positivities of electrocardiographic criteria of left ventricular hypertrophy proposed by the western authorities, when applied to Koreans, are mainly due to the precordial voltage criteria. Criteria with a high true positivity and low false positivity indicating., more reliable and more appropriate for Korean males, were RV6>20mm, RV(5-6)>==27mm and SV2+RV(5-6)>45mm in the precordial leads, RaVL>==7.6mm in the extremity leads and point score system. In females, they were similar to those in males except that criterion SV1+RV(5-6)>35mm was more appropriate than SV2+RV(5-6)>45mm. However, these selected criteria also revealed higher false positivities in Koreans than in Westerns, and obviously still further studies are needed to establish more reliable criteria for Koreans.
