A 63-year-old male patient with extensive carcinoma in situ of the urinary bladder was found to have unsuspected transitional cell carcinoma of the prostate. Mapping of the totally embedded radical cystectomy specimen demonstrated diffuse, multifocal, epithelial abnormalities, ranging from mucosal atypia to the nonpapillary carcinoma in situ with extension to the urethra, prostatic ducts and glands, seminal vesicles and ureter, probably reflecting individual urothelial susceptibility in reaction to carcinogenic stimulus. The importance of prostatic assessment in the evaluation of the patient with carcinoma in situ of the urinary bladder is emphasized.

We studied distribution of fibronectin in paraquat-induced adult fibrotic lung by indirect immunofluorescence and indirect immunoperoxidase methods, using affinity-purified antifibronectin IgG peroxidase conjugates and antifibronectin IgG FITC conjugates. In contrast to the relative paucity of staining in normal lung, there was a marked increase in interstitial staining for fibronectin in this fibrotic lung. This marked alterations in the apparent amounts and distribution of fibronectin in fibrotic human lung suggest its involvement in the cellular events accompanying human lung fibrosis.

Carbamylated hemoglobin (CarHb) is formed by the reaction of hemoglobin with cyanate derived from the spontaneous dissociation of in vivo urea. Previous studies have shown that formation of CarHb depends upon both the severity and the duration of renal failure. To study the clinical significances of CarHb in Korean patients with chronic renal failure, we measured CarHb levels by high-performance liquid chromatography in 159 CRF patients and 46 normal controls. Patients with CRF had a higher CarHb concentration than normal controls (107.9+/-58.8 vs 35.1+/-14.2 microgramVH/gHb; P<0.001). In patients with CRF, nondialysis group had a higher value than dialysis group (129.8+/-77.9 vs 98.7+/-46.1 microgramVH/gHb; P<0.05). There were no siginificant difference in CarHb levels between hemodialysis (92.0+/-35.8microgramVH/gHb) and peritoneal dialysis (106.7+/-55.3microgramVH/gHb) groups. CarHb levels were not different between diabetic and nondiabetic patients in predialysis and hemodialysis groups. Although there was a significant difference in peritoneal dialysis group, the BUN levels were also lower in diabetic patients than nondiabetic patients. There were no correlation between CarHb and HbA1c percentage in patients with diabetes. CarHb levels were positively correlated with BUN (r=0.489; P<0.001) and creatinine (r=0.458; P<0.01) concentrations. There were negative correlations between CarHb and both Kt/V (r=-0.358; P<0.05) and URR (r=-0.415; P<0.05) in hemodialysis patients. In conclusion, CarHb may be a useful index of uremic control in patients with chronic renal failure, and are independent of the mode of dialysis and the presence of diabetes.

The result of artificial skins made with collagen is poor after grafting over the full thickness wounds due to their rapid degradation by enzymatic cleavage. This study is an in vivo study of an artificial skin made with a biodegradable polymer, which can better address the problem of the collagenous artificial dermis. To investigate the availability of a biodegradable polymer for an artificial dermis and to get an information about the optimal degradation rate of a polymer for an artificial dermis, we made an artificial dermis by seeding of fibroblasts within the vicryl mesh and made a bilayer artificial skin by covering the artificial dermis with cultured keratinocytes. And these artificial dermis and artificial skin were evaluated in a full thickness wound model. The results are as followings: 1. The artificial dermis was available for grafting for 1 week culture of vicryl mesh-fibroblast. 2. The artificial dermis retarded the contraction of full thickness wounds. 3. The artificial dermis generated the granulation tissue and accepted the STSG completely. 4. The generated tissue from the artificial dermis had incorporated into the surrounding tissue by 4 weeks postgrafting. 5. Vicryl in the artificial dermis became to biodegrade from the culture period and absorbed completely by 5 weeks. 6. The epidermal portion was poorly differntiated during in vitro culture period. In conclusion, the polymer-fibroblast graft can retard the wound contraction and generate a new tissue permitting a useful dermal replacement. And to get more optimal results, another polymer which has slower biodegradation rate than vicryl should be used for the artificial dermis and the epidermal portion should be differentiated after in vivo grafting.

As the traffic accidents and occupational accidents increase, the pure blow out fracture has been increased. If we could know the prognostic information of the pure blowout fracture according to the fracture sites, it would be of benefit in consulting the patients preoperatively and in planning the treatment. In this study we defined the posterior wall fracture as that extending 2 cm from orbital rim and the anterior wall fracture as that presenting within 2 cm from orbital rim. These fractures were individually classified into inferior wall fractures, medial wall fractures, and combined inferior and medial wall fractures, based on the operative finding and the preoperative CT scanning. We experienced 76 cases of pure blowout fracture patients underwent surgical correction and followed up the subsidence of diplopia and extraocular muscle limitation with ophthalmic Hess test. The results obtained are as following: 1. Posterior wall fractures were improved more slowly than anterior wall fractures. 2. Combined inferior and medial wall fractures were improved more slowly than isolate inferior wall or medial wall fractures. These results may be related to the difference of the traumatic forces and the anatomical structure of the fracture sites. These results inform the importance of accurate anatomical reconstruction of fracture sites and can be used as a prognostic information of the pure blow out fractures.

The pubic louse, Pthirus pubis is a blood-sucking ectoparasite adapted to hold onto pubic, axillary and body hairs. It is usually confined to the pubic and inguinal region. However, it may also rarely involve the scalp and eyelashes. We report two cases of phthiriasis occurring on unusual sites, the first case occurring on the scalp of a 5 month-old male infant, and the second case on the eyelashes of a 49-year-old fe-male.
