BACKGROUND: Laser resurfacing of cutaneous scars, rhytides, and photodamaged skin has become very popular. Pulsed erbium:YAG laser resurfacing has recently come into favor for the treatment of pitted acne scars. OBJECTIVE: This study was designed to investigate the efficacy and safety of pulsed erbium:YAG laser in cutaneous resurfacing of pitted acne scars. METHODS: 100 patients with pitted acne scars were enrolled in this study. All patients were treated by means of a pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 to 1000mJ/pulse and fluences used varied between 5-15J/cm2. Photographs of the face were obtained at baseline and 2 week postoperatively. Two weeks after treatment, postoperative care such as applying hydroquinone 4% and tretinoin 0.05% was recommended for 2 to 4 weeks. RESULTS: Out of 100 patients, 20% of patients showed an excellent response, 50% a good response, 21% a fair response and 9% a poor response. After 6 months, erythema had developed in two patients and and three patients had developed postinflammatory hyperpigmentation, hypopigmentation and delayed contact dermatitis. CONCLUSION: Treatment with pulsed erbium:YAG laser shows high efficacy and low morbidity in pitted acne scar resurfacing.

Trichoblastoma is a rare benign neoplasm that arises in the follicular germinative cells. The terminology and histopathological definition of this tumor is both complex and confusing. Trichoblastoma occurs only on the hair bearing areas such as the scalp, face and pelvic area with varying degrees in size. We describe a case of trichoblastoma occurring as a nodule on the nose. The tumor was composed of numerous lobules of basaloid epithelial cell nests with distinct peripheral palisading of nucleoli that were clearly demarcated from the stroma.

The prevalence of dermographism in 96 patients of acute or chronic urticaria was studied using dermographic tester. The results were summarized as follows : 1. The prevalence rate of dermographism in acute or chronic urticaria was 26.0% (25/96). 2. Dermographism was more common in acute or chronic urticaria than in the general population(p<0.005). 3. There was no significant difference in the prevalence rate of dermographiam between acute and chronic urticaria. 4. The prevalence rate of dermographism was not significantly correlated with the level of serum IgE.

Cardiac size of 291 new-born infants was measured using the method illustated on Fig 1. Among the 291 infants,53 were asphyxiated, and asphxia was only regared from Apgar score below 6 on 1 min. and 5 min. Remaining 238infants were normal, and classified to group with lung abnormalities and without lung abnormalities on chest A-Pfilm. The results are as follows; 1. The average CTR. of normal group was 52.37(C/T1;54.89, C/T2;49.43, C/T3;49.15, C/T;55.97) 2. The average CTR. of asphxiated group was 54.91 (C/T1;57.13, C/T2;51.69, C/T3;51.94,C/T4;58.25) 3. Consequently, asphyxiated infants revealed larger cardiac size than normal infant group.

PURPOSE: To evaluate the predictive value of the early response of 18F-flurodeoxyglucose positron emission tomography (FDG PET) during concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: FDG PET was performed before and during CCRT for 13 NSCLC patients. Maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were measured and the changes were calculated. These early metabolic changes were compared with the standard tumor response by computed tomograms (CT) one month after CCRT. RESULTS: One month after the completion of CCRT, 9 patients had partial response (PR) of tumor and 4 patients had stable disease. The percent changes of SUVmax (%DeltaSUVmax) were larger in responder group than in non-responder group (55.7% +/- 15.6% vs. 23.1% +/- 19.0%, p = 0.01). The percent changes of SUVmean (%DeltaSUVmean) were also larger in responder group than in non-responder group (54.4% +/- 15.9% vs. 22.3% +/- 23.0%, p = 0.01). The percent changes of MTV (%DeltaMTV) or TLG (%DeltaTLG) had no correlation with the tumor response after treatment. All the 7 patients (100%) with %DeltaSUVmax > or = 50% had PR, but only 2 out of 6 patients (33%) with %DeltaSUVmax < 50% had PR after CCRT (p = 0.009). Likewise, all the 6 patients (100%) with %DeltaSUVmean > or = 50% had PR, but only 3 out of 7 patients (43%) with %DeltaSUVmean < 50% had PR after CCRT (p = 0.026). CONCLUSION: The degree of metabolic changes measured by PET-CT during CCRT was predictive for NSCLC tumor response after CCRT.

Most insects including the honeybee cause erythema and edema at the site of a sting in non-allergic individuals. This reaction usually resolves within a few days. However, in certain cases, the persistence of inciting materials in the cutaneous tissue may promote a local inflammatory foreign body reaction. Localized nodular lesions were seen in our two patients and erythemstous patches were present in one patient due to rarely encountered complications induced by retained sting materials. In these cases histopathology showed multiple foci of foreign body granuloma containing yellow refraetile material in the center surrounded by histiocytes and foreign body giant cells. The granulomatous skin lesions in these patients were treated with intralesional injections of triamcinolone acetonide and partial excisions of the nodular masses were performed.

Eight patients with primary non-transitional cell carcinoma of the bladder during the period from January 1978 to December 1982 were reviewed, and following results ware obtained. 1. Primary non-transitional bladder carcinomas were 8 cases (11%) of 52 bladder carcinomas. 2. The age distribution was from 28 years to 72 years. Male to female ratio was 5 to 3. 3. Hematuria was presented in all cases, dysuria in 2 cases, frequency in 2 cases, lower abdominal pain in 2 cases. 4. Histopathological findings showed squamous cell carcinoma in 3 cases, adenocarcinoma in 3 cases, undifferentiated carcinoma in 1 cases, carcinosarcoma in 1 cases. According to 2Iewett classification, the degree of invasion was stage C in 5 cases, stage B2 in 1 case, stage B1 in 1 case and stage A in 1 case. 5. Five cases arised on lateral wall, 3 cases on dome, 1 case on posterior wall and 1 case on trigone. Four cases were nodular in type. 2 cases were papillary and 2 cases were smooth surface round pedunculated mass. Five cases were single and 3 cases were multiple. 6. 1) In stage C of adenocarcinoma, partial cystectomy was made in 1 case, radical cystectomy with ureteroileocutaneostomy in 1 case, partial cystectomy with postoperative irradiation in 1 case. In former two case, tumor metastasized to periaortic lymphnodes and lumber vertebrae after 6 months post-operatively. 2) Partial cystectomy was performed in 1 case of carcinosarcoma in stage A, tumor recurrence or metastasis did not occur after 1 year post-operatively. 3) In 2 cases of squamous cell carcinoma of stage C, preoperative irradiation with total cystectomy and ureterocutaneostomy was made in 1 case, total cystectomy with ureterocutaneostomy in 1 case and partial cystectomy with 5-FU instillation into the bladder was performed in 1 case of stage B2. In all cases, we couldn't follow up post-operatively. 4) In stage B1 of undifferentiated carcinoma, radical cystectomy with ureteroileocutaneostomy was performed. This case also couldn't be followed up.
