Purpose: Although the autogenous tissue transfer has been the mainstay of the breast reconstruction, concern for the donor site morbidity can lead to the superseded method using tissue expander with implant or permanent expander-implant. However, the additional procedure of tissue expansion possibly cause discomfort and raise the cost. We tried to verify the efficacy of using the saline-filled breast implant by itself for the safe and convenient immediate breast reconstruction modality if the patients have small, round and non-ptotic breasts and the sufficient breast skin can be saved with mastectomy. Methods: From July 2002 to July 2005, 29 breasts of 26 patients were restored only with the saline-filled breast implant immediately after the skin sparing or nipple-areolar skin sparing mastectomy in Asan Medical Center. A pocket with pectoralis major and serratus anterior muscle was created and the implant was covered with this muscle pocket. Simultaneous contralateral augmentation was performed in patients whose mastectomy specimen weighed less than 100g. Results: Using only the saline-filled breast implant resulted in the successful reconstruction with few complications including partial necrosis of nipple areolar skin (five cases, 17.2%), capsular contracture (three cases, 10.3%), hematoma (one case, 3.4%), depigmentation of areolar skin (one case, 3.4%), hypertrophic scar (one case, 3.4%), which were all healed by conservative management. There were no significant complications such as implant exposure and subsequent removal. Conclusion: Immediate breast reconstruction only with the saline-filled breast implant can be a satisfactory alternative option for the patients whose breast is small, round and non-ptotic, especially when the nipple-areolar skin of the breast is preserved in the mastectomy.

Synthetic pyrethroids are analysis of a natural chemical moiety, pyrethrin derived from the pyrethrum plant Chrysanthemum. The natural pyrethrin structure has been modified to be highly lipophilic and photostable, creating an effective pesticide and resulting in an increased presence in the environment. Worldwide, they are commonly used insecticides against ticks, mites, mosquitoes, and as treatment for human head lice and scabies. Therefore, human exposure to their compounds in extensive. Several studies on the effects of pyrethroids on thyroid hormone regulation, estrogen and androgen function have been reported and yet little has been done try assess their potential hormonal activities. Among humans, a pyrethroid compound was suggested to be the causal agent for gynecomastia in a group of Haitian men. The reports suggest that some pyrethroid compounds are capable of disrupting endocrine function. Therefore, we examined estrogenic/antiestrogenic potential of three pyrethroid insecticides, that is permethrin, allethrin and fenvalerate in human breast cancer cell and action mechanism mediated by the estrogen receptor. Fenvalerate showed weak estrogenic activity but aallethrin and permethrin showed no effect. In combination with high levels (10$^{-10}$ M, 10$^{-11}$ M) of 17$\beta$-estradiol and three synthetic pyrethroids inhibited cert proliferations in MCF7-BUS cell by 17$\beta$-estradiol. Whereas, fenvalerate increased cell proliferative activity at lower level of estradiol (10$^{-12}$ M, 10$^{-13}$ M). The relative affinities to the estrogen receptor were observed by allethrin and permethrin treatment, but not by fenvalerate. These results indicated that some of pyrethroid insecticides may modulate estrogen functions in human breast cancer cell. The action mechanisms of estrogen receptor mediated antiestrogenicity by allethrin and permethrin were postulated.

Objectives : Antipsychotic-induced hyperprolactinemia causes physical symptoms, such as amenorrhea, galactorrhea, gynecomastia, sexual dysfunction, and bone density loss, as well as psychiatric symptoms, such as depression and cognitive impairments. This study aimed to clarify the associations among hyperprolactinemia caused by antipsychotics in patients with schizophrenia, psychiatric pathology, and psychosocial factors. Methods : Ninety-nine patients with schizophrenia in the psychiatry department of a university hospital were registered between 2015 and 2017. All participants were assessed using structured questionnaires to elucidate psychopathology, social function, quality of life, and hyperprolactinemia-related side effects. The standard levels for hyperprolactinemia were 24ng/mL for women and 20ng/mL for men. Results : The average prolactin levels were $73.45{\pm}49.37ng/mL$ in patients with hyperprolactinemia and $9.16{\pm}6.42ng/mL$ in those without hyperprolactinemia. The average prolactin level in women was significantly higher than that in men(p=0.04). Risperidone was most commonly administered in patients with hyperprolactinemia(58.1%, p<0.01), while aripiprazole was most commonly administered in those without hyperprolactinemia(44.7%, p<0.01). Patients with hyperprolactinemia had significantly higher Positive and Negative Syndrome Scale(p=0.03) and Patient Health Questionnaire-9(p=0.05) scores and had significantly lower Social and Occupational Functioning Assessment Scale(p=0.04) and Strauss-Carpenter Levels of Functioning Scale(p=0.03) scores than patients without hyperprolactinemia. There were no significant differences in side effects or quality of life between the two groups. Conclusion : These findings demonstrate that hyperprolactinemia confers negative effects on depression and social function, but does not directly affect the quality of life. These results suggest that patients with schizophrenia who take antipsychotics that increase prolactin or cause side effects of hyperprolactinemia need to be assessed and receive interventions for depression.

Purpose: To evaluate long-term local control rate and toxicity in patients treated with external beam radiotherapy (EBRT) for pituitary adenomas. Materials and Methods: We retrospectively reviewed the medical records of 60 patients treated with EBRT for pituitary adenoma at Korea University Medical Center from 1996 and 2006. Thirty-five patients had hormone secreting tumors, 25 patients had non-secreting tumors. Fifty-seven patients had received postoperative radiotherapy (RT), and 3 had received RT alone. Median total dose was 54 Gy (range, 36 to 61.2 Gy). The definition of tumor progression were as follows: evidence of tumor progression on computed tomography or magnetic resonance imaging, worsening of clinical sign requiring additional operation or others, rising serum hormone level against a previously stable or falling value, and failure of controlling serum hormone level so that the hormone level had been far from optimal range until last follow-up. Age, sex, hormone secretion, tumor extension, tumor size, and radiation dose were analyzed for prognostic significance in tumor control. Results: Median follow-up was 5.7 years (range, 2 to 14.4 years). The 10-year actuarial local control rates for non-secreting and secreting adenomas were 96% and 66%, respectively. In univariate analysis, hormone secretion was significant prognostic factor (p = 0.042) and cavernous sinus extension was marginally significant factor (p = 0.054) for adverse local control. All other factors were not significant. In multivariate analysis, hormone secretion and gender were significant. Fifty-three patients had mass-effect symptoms (headache, dizziness, visual disturbance, hypopituitarism, loss of consciousness, and cranial nerve palsy). A total of 17 of 23 patients with headache and 27 of 34 patients with visual impairment were improved. Twenty-seven patients experienced symptoms of endocrine hypersecretion (galactorrhea, amenorrhea, irregular menstruation, decreased libido, gynecomastia, acromegaly, and Cushing's disease). Amenorrhea was abated in 7 of 10 patients, galactorrhea in 8 of 8 patients, acromegaly in 7 of 11 patients, Cushing's disease in 4 of 4 patients. Long-term complication was observed in 4 patients; 3 patients with cerebrovascular accident, 1 patient developed dementia. Of these patients, 3 of 4 received more than 60 Gy of irradiation. Conclusion: EBRT is highly effective in preventing recurrence and reducing mass effect of non-secreting adenoma. Effort to improve tumor control of secreting adenoma is required. Careful long-term follow-up is required when relatively high dose is applied. Modern radiosurgery or proton RT may be options to decrease late complications.
