The effect of intravesical formalin instillation as a therapeutic modality for intractable bladder hemorrhage in well known. And despite clear evidence of therapeutic efficacy of intravesical cytotoxic drugs and / or BCG immunotherapy, there have been substantial recurrences during follow up after transurethral resection for superficial bladder tumor. If formalin injected at the bed of superficial bladder tumor is able to coagulate and necrotize the tumor, it will be greatly helpful to the patients with recurrent bladder tumor developed during follow up. Since this technique is applicable on outpatient basis, an economical as well as a psychological burden of the patients can be reduced considerably. The purpose of this study is to evaluate the effect of submucosal formalin injection on rat bladder wall. 36 healthy adult male Sprague-Dawley rats (weighing 350 gm in average) were divided into 3 groups: In Group I (control group), 0.01ml of normal saline was injected submucosally at the left posterolateral wall of the bladder opened under intraperitoneal Nembutal anesthesia; In Group II and III, 0.01 ml of 10% and 4% formalin, respectively, were administered at the same site as in the Group I, two rats in each group were sacrificed at day 1, 2, and 3, and week 1, 2, and 4 after injection, respectively. Gross and microscopic examination of the cystectomized specimen were done in each group. In the Group II, bladder stones were formed at week 1, and in both the Group I and III, stones were seen at week 2 post injection. There was no significant difference in histologic findings of the bladder between the group II and III. Mucosal ulcer and/or prominent mucosal disruption was observed at 24 hours after injection in both Group II and III. Epithelial regeneration began at day 2, and was marked at day 3, and epithelial lining was almost normalized one week after injection. Subepithelial edema, telangiectasia and inflammatory reaction were prominent at 24 hours post formalin injection. Subepithelial edema persisted in moderate degree for 1 week. Telangiectasia and inflammatory reaction were noted for 4 weeks. Mild degree of these findings also appeared in the control group. Fibroblastic proliferation appeared at day 2 and persisted in moderate degree for 4 weeks. There has been no mortality or bladder perforation. These results suggest that clinical application of this technique is feasible for the selected cases of recurrent, solitary superficial bladder tumor. However, optimal dosage of formalin in relation to the size of the lesion remains to be investigated.

The peripheral blood eosinophil and serum IgE level in 53 patients with atopic dermatitis (AD) were measured. The patients were divided into 2 groups by severity(mild and severe grous) and into 3 groups by the associated respiratory atopic deseases and/or their family history : respiratory group(patient, with both AD and respiratory atopy), family history group (patient with both AD and family history of respiratory atopy), and atopic group(patient with neither respiratory atopy nor family history of respiratorv atopy). We designed to study which factors are important in the elevation of serum IgE and peripheral blood eosinophil level in AD, and to know possible relationships between the serum eosinophil and IgE level and the several groups of AD. The results are as follows : 1. Peripheral eosinophil counts were higher in severe group(224.8/mm) than in mild group (180.0/mm)(p<0.05). 2. Peripheral eosinophil counts were 220.0/mm in atopic group, l65.0/mm in family history group, and 332.4/mm in respiratory group, but there was no stitistically significant difference among 3 groups. This suggests that concomitant respiatitiry atopy or a family history of respiratory atopy is not an important factor in the elvation of peripheral blood eosinophil counts in AD. 3. Serum IgE was higher in severe group(443.2IU/ml) than in mild group(231.5IU/ml)(p<0.05). 4. Serum IgE level in respiratory group(754.6IU/ml) were signifiiantlly higher than in atopic (286.6IU/ml) or family history group(342.0IU/ml)(p<0,01). But there was no significant. difference between family and atopic group. This result suggests that concomittent respiratory atopy is a potential factor in elevation of serurn Igi in AD. 5. Slightly high correlation between peripheral blood and IgE level appeared in all 53 patients (r=0.434) and severe group(r=0.480). But, respiratory group(r=0.060), family history group(r=0.111) and atopic group(r=0.202) showed poor relationships.

PURPOSE: We evaluated the effects of amitriptyline in patients with urinary frequency or pelvic pain syndrome and compared with propiverine hydrochloride (BUP-4(R)) and diazepam (Valium(R)). MATERIALS AND METHODS: One-hundred and sixty-eight patients with urinary frequency or pain were included and 38 out of 168 patients were lost to follow up. The patients with interstitial cystitis, UTI and neurogenic bladder were excluded. Amitriptyline group were instructed to take 25mg to 75mg of amitriptyline before bed. Propiverine hy drochloride and diazepam group were instructed to take 20mg, 4-6mg before bed, respectively. The clinical effects and side effects were evaluated after 4 weeks of medication. RESULTS: In the amitriptyline group, 73.1% in 78 patients with frequency, 68.3% in 60 pain, 65.6% in 32 nocturia, 53.8% in 26 weak urinary stream, 53.8% in 13 dysuria, 72.7% in 11 urgency showed symptom improvement. Urinary frequency and pain score were significantly decreased in the amitriptyline group. In the propiverine hydrochloride group, 66.7% in 21 patients with frequency, 38.8% in 18 pain showed symptom improvement. In the diazepam group, 37.5% in 24 patients with frequency, 31.3% in 16 pain showed symptom improvement. Side effects of amitriptyline had appeared in 24 (27.6%) out of 87 patients; 17 cases of dry mouth, 10 drowsiness, 2 agitation, 2 nausea, 1 constipation and 1 skin rash. CONCLUSIONS: Amitriptyline is useful in vague voiding symptoms especially in urinary frequency and chronic pelvic pain syndrome. It is equally effective in both men and women. Side effects are minimal and tolerable. A double-blind placebo-controlled trial is necessary for general acceptance in the future.

We report an unusual case of sebaceous hyperplasia in an 18-year-old male manifestated clinically as yellowish, grouped papules with a linear distribution, present on the right side of forehead since birth. Histopathologically, a large sebaceous gland composed of numerous lobules grouped around a centrally dilated duct was seen. The sebaceous lobules distributed in the upper dermis showed direct connection to the skin surface, which suggested a transepidermal elimination of sebaceous lobules.

The onset of systemic scleroderma in the first. decade of lif occurs in less than 1.5% of instances. Systemic sclerodrma in childhood have been characterized by less severe visceral involvement and a benign course We report a boy, aged 7 years, with a history of Raynaid; phenomenon and dysphagia. He had a mask-like face, flexion contracture of hands and knee joints, digital pitting scars, ichthyosiform skin change on leg and hyperpigrnented induration on all extremities and trunk. Antinuclear antibodies were positive in nucleolar type and Scl-70 antiocy was also present. On radiologie study, the pattern of reflux esophagitis and resorption of the listal ends of all phalanges were nated. Histopathological findings were compatible with sclerodma. He was treated with Penicillamine-D and oral corticosteroic with good improvernent.

BACKGROUND: Tufted angioma is an uncommon slowly progressive vascular tumor found typically in infants and young children with characteristic histologic findings, so called "cannonball" appearance. OBJECTIVE: The purpose of this study was aimed to investigate the clinical and histopathological characteristics of tufted angioma and the response to intralesional steroid. METHODS: Clinical information of 10 patients with tufted angioma diagnosed in Severance hospital and Pundang CHA hospital from 1983 to 1999 was obtained from the medical records and clinical follow-ups. We re-evaluated 10 biopsy specimens obtained from them with routine H&E staining. RESULTS: Five male and five female patients were included. In 9 patients the lesion appeared before 2 months of age. Four had a lesion at birth. The thigh was the most common site. The clinical symptoms were diverse, but characteristically tenderness was present in most cases. In all the patients the lesions had a tendency to spread progressively. Microscopically, numerous, distinct, variably sized, tightly packed capillary and endothelial cellular lobules were scattered in the dermis. There were characteristic semilunar spaces adjacent to the capillary tufts. Six patients received intralesional triamcinolone. This treatment was found to be effective in 5 patients who experienced remarkable improvement. The improved cases had similar histologic findings which were composed of cellular mass more than lumen formation. We classified our specimens into two categories, one with more cellular mass and the other with more lumen formation in relative proportion. The former was different from the latter in that it had more solid appearance and more definite margin. And we realized that it was useful to divide into these two categories since its response to treatment could be different. CONCLUSIONS: Tufted angioma is a relatively uncommon disease with characteristic histopathologic findings. It seems not to regress spontaneously. So early treatment is required to pre-vent further spreading up to the extent. We treated 6 patients with intralesional injection of triamcinolone and 5 patients experienced marked improvement which had more cellular mass more than lumen formation histopathologically.

BACKGROUND: Cockroaches are important components of house dust allergens. In spite of significant subject reactivity to cockroach extracts, the specific source of the allergen remains unclear. OBJECTIVE: This study was performed to identify the important allergens in German cockroach whole body (GWBE), egg (GEE) and fecal (GFE) extracts in Korean atopy, and to compare the reactivity of GWBE and GEE by Western blot inhibition. METHODS: Sera from 11 subjects with Korean atopy were used for sodium dodecil sulfate polyacrylamide gel elctrophoresis (SDS-PAGE) and Western blot analysis. RESULTS: Allergenic fractions in German cockroach extracts were numerous and distributed throughout the wide range of molecular weights. The important allergens of GWBE, GFE and GEE were similar to each other by using SDS-PAGE and Western blot ysis. The aUergen bands at 55 kd showed the most significant reactivity; in GWBE, GFE and GEE 73%, 82%, 55%, respectively. Other bands exhibiting significant activity were the 67 kd band with 37%, 19% and 19%, the 64 kd band with 64%, 37% and 9% respectively. Furthermore, Western blot inhibition investigations revealed that either GWBE or GEE could almost completely inhibit the reactivity of the other extract. CONCLUSION: This study confirms that the 55 kd allergen can be considered as the major allergen in Korean atopy and demonstrated that the GWBE and GEE antigens have identical IgE-binding sites.
