Basal cell carcinomas(BCCs) are usually treated with ablative proccdures, but a nonsurgical treatment would conserve tissue and obtain a better cosmetic out come as well as treat patients who refuse surgery or those who are not good surgical candidates. Because of inadequate drug penetration, low cure rates, high recurence rates, and adverse reactions, such as contact dermatitis, topical 5-fluorouracil(5-FU) is unsaitble to treat nodular BCCs. But, int,ralesional 5-FU has been reported to be effective for nodular BCCs. The efficacy and safety of intralesional injection of 5-FU have been evaluated for treatment of BCCs. The results revealed that intralesional injection of 5-FU seems to be effective in the treatment of various premalignant and malignant skin lesions as well as BCCs without side effects.

Twenty-three cases of the scaphoid fracture which were treated at the Department of the Orthopaedic Surgery, Catholic University Medical College during the period of december 1978 to december 1987 were analysed. The main purpose of this study was to clarify the significant factors affecting the union rate of the scaphoid fracture. The results obtained were as follows ; 1. The great majority of 23 cases was male with mean age 31. 2. Ulnar deviated stress oblique view with msking a fist was the most reliable means for diagnosing the fracture, location of fracture and stability of wrist after scaphoid fracture. 3. Union rate was obtained from 88.8% in undisplaced fresh fracture, 85.7% in displaced fresh fracture and 71.4% in old neglected fracture. 4. The union rate and associated factors affecting the prognosis after scaphoid frscture seems to be depended on the location of fracture, the severity of initial displacement of fracture fragments, time elapsed of treatment after fracture and accompanied injuries around the ipsilateral wrist.

Objectives: This study examined the research trends in the field of the five addictions, examining the correlations and co-occurrence among addiction studies. Methods: Bibliographic information from papers was used to examine the correlations and cooccurrence between different fields of addiction. The analysis covered the entire period and specific time frames. Correlation analysis was conducted using cosine similarity, while co-occurrence analysis was performed using text network analysis. Results: An analysis of the correlations and co-occurrence among the five addictions revealed the following. First, since 2000, studies on internet and smartphone addiction have become more active, leading to a significant increase in research connections between the different types of addiction. Second, there is a high correlation between alcohol addiction and internet addiction, with shared research topics being actively explored. Finally, the most commonly addressed topic across studies on the five addictions is adolescent addiction. Conclusion The significance of this study lies in its contribution to understanding the trends in addiction-related research and the insights into the treatment of cross-addiction.

Schizophrenia is a devastating mental illness that can lead to deterioration in the social and occupational functioning of affected individuals with a major cost to society. A wide range of studies suggest a genetic component to the inheritance of schizophrenia. The molecular genetic studies on schizophrenia have been actively performed since late 1980s. In linkage studies, no loci were replicated across studies and there were no loci surpassing genome-wide significance. Candidate gene association studies showed generally inconsistent results and there were no enrichment of smaller P-values. In the GWAS era, the community has coalesced into large international consortia. The largest schizophrenia GWAS to date is 50,000 samples and efforts are ongoing to accumulate 50,000 cases and 50,000 controls as part of 'PGC2' collaboration. With the limitation of GWAS results, several alternatives are being explored. In genotyping, the concepts of allelic spectrum including from common polygenic to rare penetrant variation are emerging. Phenotypes include all phenomena beyond DNA. The developments in transcriptomic & proteomic approach and intensive research on endophenotype will bring crucial insights into the nature of schizophrenia in the future. But there still remains our task about research on many factors including environment that influence gene expression (epigenetics), age, and gender.

Psoriasis is a relatively common disorder that affects at least 1-2% of the population, however, the pathogenesis is not fully understood yet. Histopathologically, psoriatic lesion is characterized by hyperplasia of keratinocyte, intraepidermal neutrophil accumulation and activated T lymphocyte infiltration in the dermis. Among many cytokines, IL-8 is known to play a role for the activation and migration for neutrophil and T lymphocyte and for the proliferation of keratinocyte. We performed immunohistochemical staining with anti-IL-8 monoclonal antibody for the active lesion, stable lesion and normal-looking skin of ten psoriatic patients and ten healthy controls. Strong expression of IL-8 in the epidermis and dermis was noted from the active as well as stable psoriatic skins. In the normal-looking skin of the psoriatic patients, only faint expression which is not different from healthy control skin, was noted. These observations indicate that the expression of IL-8 is increased in psoriatic lesion, and IL-S is important for the initiation and maintenance of psoriasis.

PURPOSE: Atopy is a state of allergic response, mediated by IgE, to common environmental allergens. In recent decades, there has been an increase in prevalence of atopic disorders in children in developed countries. The factor associated with the rise of atopy incidence may be declining exposure to some infection opportunities. The aim of this study is to determine if the immune response to Mycobacterium tuberculosis can suppress atopy by investigating the association between tuberculin responses and serum IgE. METHODS: We divided the patients into two groups according to tuberculin skin test. Group A showed positive response (induration diameter > or =10mm), while Group B showed negative response (induration diameter< l0mm). A comparison was made between the two groups in terms of age, sex, serum total IgE and allergen-specific IgE. RESULTS: Twenty-one patients comprised Group A and 72 comprised Group B. The mean serum total IgE concentration and the number of patients showing positive MAST in Group B was significantly higher than that of Group A (P<0.05). CONCLUSION: In our study, there was an inverse association between delayed hypersensitivity to Mycobacterium tuberculosis and atopy.
