Objectives Thyroid hormone deficiency during the neurodevelopmental period can impair brain development and induce psychiatric symptoms. This study examined the association between thyroid dysfunction and the severity of symptoms in schizophrenia patients, and the treatment response of patients with schizophrenia. Methods Three hundred thirty-eight schizophrenia patients, with no prior history of thyroid disease or taking medication associated with it, were studied. We assessed the blood thyroid hormone level, the Brief Psychiatric Rating Scale (BPRS) scores on the day of admission and discharge, admission period, dose of administered antipsychotics, and the number of antipsychotic combinations. The collected data were subsequently analyzed using the Kruskal-Wallis test and Pearson's chi-square test. Results The percentage of schizophrenia patients who presented with abnormal thyroid hormone level was 24.6%. High total triiodothyronine (TT3) (p = 0.003), low TT3 (p = 0.001), and high free thyroxine (fT4) (p < 0.001) groups showed a higher BPRS score on admission than did the normal thyroid hormone group, while thyroid stimulating hormone (TSH) levels were not significantly correlated with the severity of symptoms. Furthermore, thyroid hormone was not associated with the treatment response assessed by the rate of BPRS score reduction, admission days, use of clozapine, and dose of antipsychotics. Conclusions The TT3 and fT4 hormone levels were significantly associated with the severity of symptoms in schizophrenia patients. These relations suggested that thyroid dysfunction may be associated with the severity of schizophrenia. And hence, further analysis of the results of the thyroid function test, which is commonly used in cases of psychiatric admission, is required.

This study aims to clarify the socio-economic factors which have an effectiveness on the social support in rural areas and analyze how it relates to the Individual Health promotion behavior. It is advised to improve social support in the community. The target population was all residents with no chronic and no serious disease who live in five villages of Chuncheon in Kangwon province during July of 2002. This study was done by the interview survey using questionnaire which was composed with questions about Medical Outcomes Study-Social Support Survey(MOS-SSS) and the health promotion behavior. MOS-SSS was translated to Korean and modified to be suitable for the study. The functional and social support variables were also added. The health promotion behavior was formed through the questions about whether or not stop smoking, stop drinking, the excise, the health examinations, attending health education, and hormone replacement therapies. The results are as follows; 1) the case of low-educated, divorce or separation to death, or the subject of social assistance, the social support was low. 2) the case of high social class, the social support was high. 3) there were no significant findings in the health status. 4) according to the analysis of correlation of health promotion behavior, the group with the most social support showed a high percentage of getting health examinations, attending health education, Hormone replacement therapies. However, the adjusted rate of smoking and drinking of trying to stop smoking and stop drinking resulted in low figures. The well-structured social support which the community can provide should be firstly given a priority for the group with low-income, low-educated, divorce or separation to death, and social assistance who are provided poor social support. Moreover, the social support service should be actively reflected to the health promotion program in the community.

Background : It is difficult to differentiate between tuberculous pneumonia and Community Acquired Pneumonia, so the diagnosis and treatment of tuberculous pneumonia can be delayed frequently. In this study, we attempted to retrospectively evaluate the clinical and radiologic characteristics of tuberculous pneumonia. Methods : We conducted a retrospective analysis of clinical characteristics of 58 patients diagnosed with tuberculous pneumonia from Nov. 1997 to May 2001 at Korea university kuro hospital. Result : The male to female ratio was 1:1 and the mean age at diagnosis was $54.5{\pm}18.6$ years. Fifty five patients were confirmed microbiologically and three patients pathologically. There were 20 patients(34.5%) who had diabetes mellitus(8cases), chronic obstructive pulmonary disease(3cases), malignancy(3cases), bronchiectasis(2cases), chronic renal failure(1cases) or long term history of corticosteroid treatment(3cases). Many patients had multilobar infiltration in chest X-ray, dominantly in the lower lobe. thirty two patients(55.2%) had infiltration in more than 2 lobes and 5 patients in more than 4 lobes. The significant correlation between the diabetes mellitus and the infiltrated Rt lower lobe(RLL) was found on the borders of confidence limit.(P=0.07<0.1). There was significant correlation between woman and infiltrated lobe(RML, RLL, LLL) excluding the both upper lobe(P=0.029). Conclusion : We must consider tuberculous pneumonia when lobar pneumonia with consolidation resistant to antibiotics, especially in the patients who have diabetes mellitus, chronic obstructive pulmonary disease, malignancy, bronchiectsis, chronic renal failure or long term history of corticosteroid treatment.

Purpose: This study was performed to evaluate the disease-free survival and risk factors of recurrence in early breast cancer patients who have undergone breast conserving surgery and radiation therapy. Materials and Methods: From March 1997 to December 2002, 77 breast cancer patients who underwent breast conserving surgery and radiation therapy were reviewed retrospectively. The median follow-up time was 58.4 months (range $43.8{\sim}129.4$ months) and the mean subject age was 41 years. The frequency distribution of the different T stages, based on the tumor characteristics was 38 (49.3%) for T1, 28 (36.3%) for T2, 3 for T3, 7 for T is and 1 for an unidentified sized tumor. In addition, 52 patients (67.5%) did not have axillary lymph metastasis, whereas 14 patients (18.1%) had $1{\sim}3$ lymph node metastases and 3 (0.03%) had more than 4 lymph node metastases. The resection margin was negative in 59 patients, close (${\leq}2\;mm$) in 15, and positive in 4. All patients received radiation therapy at the intact breast using tangential fields with a subsequent electron beam boost to the tumor bed at a total dose ranging from 59.4 Gy to 66.4 Gy. Patients with more than four positive axillary lymph nodes received radiation therapy ($41.4{\sim}60.4\;Gy$) at the axillary and supraclavicular area. Chemotherapy was administered in 59 patients and tamoxifen or fareston was administered in 29 patients. Results: The 5 year overall survival and disease-free survival rates were 98.08% and 93.49%, respectively. Of the 77 patients, a total of 4 relapses (5.2%), including 1 isolated supraclavicular relapse, 1 supraclavicular relapse with synchronous multiple distant relapses, and 2 distant relapses were observed. No cases of local breast relapses were observed. Lymph node metastasis or number of metastatic lymph nodes was not found to be statistically related with a relapse (p=0.3289) nor disease-free survival (p=0.1430). Patients with positive margins had a significantly shorter disease-free survival period (p<0.0001) and higher relapse rates (p=0.0507). However, patients with close margins were at equal risk of relapse and disease-free survival as with negative margins (p=1.000). Patients younger than 40 years of age had higher relapse rates (9.3% vs. 0%) and lower disease-free survival periods, but the difference was not statistically significant (p=0.1255). The relapse rates for patients with tumors was 14% for tumor stage T2, compared to 0% for tumor stage T1 tumors (p=0.0284). A univariate analysis found that disease-free survival and relapse rates, T stage, positive resection margin and mutation of p53 were significant factors for clinical outcome. Conclusion: The results of this study have shown that breast conservation surgery and radiation therapy in early breast cancer patients has proven to be a safe treatment modality with a low relapse rate and high disease-free survival rate. The patients with a positive margin, T2 stage, and mutation of p53 are associated with statistically higher relapse rates and lower disease-free survival.

The major symptoms of terminally ill cancer patients are fatigue, loss of energy, feeling of helplessness, poor appetite and pain as well as general weakness, which are very similar to symptoms of adrenal insufficiency. Adrenal insufficiency-induced symptoms widely vary from mild symptoms to life-threatening conditions and may be resulted from variable medical causes. For terminally ill cancer patients who are hospitalized for palliative care, opioid agents are prescribed to control moderate to severe pain. The use of acute or chronic opioid agents is believed to negatively affect adrenal gland function. In most studies of opioid effects (preclinical/clinical with animal subjects or and patients suffering non-malignant pain, adrenal insufficiency and hormonal abnormalities were observed as side effects. However, opioid-induced adrenal insufficiency has been rarely reported in studies with patients with malignant cancer pain. Relationship between the type, treatment period, dosage of opioid agents and hormonal abnormalities can be examined by measuring the functional level of the adrenal glands. We hope to improve patient's quality of life by indicating hormone substitution to treat symptoms of adrenal insufficiency.

Acne is known as the most common skin disease. It commonly occurs during adolescents, but it is also present in children and adults because of air pollution, drug abuse and so on. In addition to the hormonal, genetic and environmental factors, Propionibacterium acnes (P. acnes) have also critical roles in outbreak of acne by inducing inflammatory mediators. Increase of sebum production provides an ideal environment for P. acnes that induce inflammation on the skin by activation of monocytic cells and stimulation of inflammatory cytokines. In this study, natural extracts were investigated for anti-inflammatory effects against inflammatory acne by P. acnes infection in terms of reducing cytokine production. Eucalyptus globulus extracts effectively suppressed mRNA synthesis of inflammatory mediators such as $TNF-{\alpha}$, $IL-1{\beta}$, IL-2, and NLRP3 in P. acnes-activated macrophages. Moreover, Eucalyptus globulus extracts inhibit activation of transcription factors, $NF-{\kappa}B$ and NFAT, which are known as key regulators of inflammatory cytokine production. This study suggests the potential of using Eucalyptus globulus extracts as alternative agents for the treatment of acne.

Living creatures possess long-conserved mechanisms to maintain homeostasis in response to various stresses. However, chronic and continuous exposure to stress can result in the excessive production of stress hormones, including catecholamines, which have harmful effects on health. Studies on the relationship between the sympathetic nervous system (SNS) and cancer have been conducted based on the traditional hypothesis that stress can promote cancer progression. Many preclinical and epidemiological studies have suggested that the regulation of ${\beta}$-adrenergic signaling, which mediates SNS activity, can suppress the progression of solid tumors. SNS activation has highly pleiotropic effects on tumor biology, as it stimulates oncogenes, survival pathways, the epithelial - mesenchymal transition, and invasion. Moreover, it inhibits DNA repair and programmed cell death and regulates the tumor microenvironment, including immune cells, endothelial cells, the extracellular matrix, mesenchymal cells, and adipocytes. Although targeted therapies on the molecular basis of tumor proliferation are currently receiving increased attention, they have clinical limitations, such as the compensatory activation of other signaling pathways, emergence of drug resistance, and various side effects, which raise the need for pleiotropic cancer regulation. This review summarizes the effects of the SNS on the development and progression of cancer and discusses the clinical perspectives of ${\beta}$-blockade as a novel therapeutic strategy for this disease.
