We report a case of primary intracranial malignant melanoma (PIMM) with extracranial metastases. The patient was an 82-year-old woman diagnosed with PIMM under the left cerebellar tentorium. We performed a tumor resection followed by gamma knife surgery. An magnetic resonance imaging at 11 months after surgery showed a local intracranial recurrence. At 12 months, vertebral metastasis was suspected, and 2-[fluorine-18]-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (FDG-PET/CT) showed multiple extracranial metastases. She died at 13 months after surgery. Although extracranial metastases of PIMM are extremely rare, we should carefully follow up extracranial metastases together with intracranial ones, especially by FDG-PET/CT, even at an early asymptomatic stage.

Social welfare center is a representation agency in the local welfare system to provide the local residents with necessary services directly. The purpose of this study is to give the fundamental materials for space program in terms of planning a social welfare center by means of analyzing spatial arrangement of each section in senior welfare activity. The structure of the social welfare center should be adopted to the reality and the center of local should pay attention to enhance the quality of life in elderly. As the aspects of the programs, distinctive program should be designed. To do so, social welfare center should be adjusted to the local situation and get flexibility on operating in the local level. Each program in senior welfare activity should be connected in the spatial organization and various space should be provided in desire of elderly. So the section of dining room and medical rehabilitation is a places mostly for the elderly. Multipurpose space for the interest and leisure and the space of the senior education facility are provided in social welfare center.

Background: Early recognition and treatment of sepsis would improve patients' outcome. But it is difficult to distinguish between sepsis and non-infectious conditions in the acute phase of clinical deterioration. We studied serum level of procalcitonin (PCT) as a method to diagnose and to evaluate sepsis. Methods: Between 1 March 2009 and 30 September 2009, 178 patients had their serum PCT tested during their clinical deterioration in the medical intensive care unit. These laboratories were evaluated, on a retrospective basis. We classified their clinical status as non-infection, local infection, sepsis, severe sepsis, and septic shock. Then, we compared their clinical status with level of PCT. Results: The number of clinical status is as follows: 18 non-infection, 33 local infection, 39 sepsis, 26 severe sepsis, and 62 septic shock patients. PCT level of non-septic group (non-infection and local infection) and septic group (sepsis, severe sepsis, septic shock) was $0.36{\pm}0.57$ ng/mL and $18.09{\pm}36.53$ ng/mL (p<0.001), respectively. Area under the curve for diagnosis of sepsis using cut-off value of PCT >0.5 ng/mL was 0.841 (p<0.001). Level of PCT as clinical status was statistically different between severe sepsis and septic shock ($^*severe$ sepsis; $4.53{\pm}6.15$ ng/mL, $^*septic$ shock $34.26{\pm}47.10$ ng/mL, $^*p$ <0.001). Conclusion: Level of PCT at clinical deterioration showed diagnostic power for septic condition. The level of PCT was statistically different between severe sepsis and septic shock.

Background Topical anesthetics, such as eutectic mixture of local anesthetics (EMLA) cream, can be applied to reduce pain before minor procedure. This trial evaluated EMLA as pretreatment for facial lacerations and compared pain, discomfort and overall satisfaction. Methods This trial included consecutive emergency department patients ${\geq}16years$ of age who presented with simple facial lacerations. At triage, lacerations were allotted to either the routine processing group or EMLA pretreatment group according to date of admission. Initially, the emergency department doctors inspected each laceration, which were dressed with saline-soaked gauze. In the pretreatment group, EMLA cream was applied during wound inspection. The plastic surgeon then completed primary closure following the local injection of an anesthetic. After the procedure, all patients were given a questionnaire assessing pain using the 10-point visual analog scale (VAS) ("no pain" to "worst pain"). All questionnaires were collected by the emergency department nurse before discharge. Results Fifty patients were included in the routine processing group, and fifty patients were included in the EMLA pretreatment group. Median age was 39.9 years, 66% were male, and the average laceration was 2.67 cm in length. The EMLA pretreatment group reported lower pain scores in comparison with the routine processing group (2.4 vs. 4.5 on VAS, P<0.05), and lower discomfort scores during the procedure (2.0 vs. 3.3, P=0.60). Overall satisfaction was significantly higher in the EMLA pretreatment group (7.8 vs. 6.1, P<0.05). Conclusions Pretreating facial lacerations with EMLA topical cream aids patients by reducing pain and further enhancing overall satisfaction during laceration treatment.

수수로가 항암요법만으로 치료한 국소 진행된 위암환자에서 치료실패의 양상을 분석해봄으로써 수술후 방사선치료의 가능성을 알아보기 위하여 1989년 6월부터 1990년 8월까지 치료받은 107명의 환자를 대상으로 후향적 분석을 시행하였다. 제2기 ($T_2N_1,\;T_3N_0$)환자는 20이었으며 제3기 ($T_3N_1,\;T_3N_2$(환자는 87명이었다 16명은 수술후 추적이 어려워 91명에 대한 분석을 시행하였다. 모든 환자는 근치적 절제술을 시행받았고 이중 57명은 수술후 항암요법을 시행하고 24명은 계속적 추적 관찰만을 하였다. 국소재발율은 항암 요법 시행군에서는 $321\%$, 추적관찰군에서는 $24\%$로 차이가 없었고 원격전이는 항암요법 시행군에서는 $12\%$ 추적관찰군에서는 $26\%$로 항앙요법 시행군에서 원격 전이가 적어지는 것을 관찰할 수 있었다. 국소 재발환자의 $52\%$는 anastomosis site에서 재발하였고 원격 전이시 가장 많이 침범되는 장기는 간이었다. 아직 추적 관찰 기간이 짧으나 수술후 방사선 치료가 최소한 $20\%$이상의 환자에서 도움이 될것으로 생각된다.

Correlation between vaccine reactogenicity and immunogenicity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unclear. Thus, we investigated to determine whether the reactogenicity after coronavirus disease 2019 vaccination is associated with antibody (Ab) titers and T cell responses. This study was prospective cohort study done with 131 healthcare workers at tertiary center in Seoul, South Korea. The degrees of the local reactions after the 1st and 2nd doses of ChAdOx1 nCov-19 (ChAdOx1) vaccination were significantly associated with the S1-specific IgG Ab titers (p=0.003 and 0.01, respectively) and neutralizing Ab (p=0.04 and 0.10, respectively) in age- and sex-adjusted multivariate analysis, whereas those after the BNT162b2 vaccination did not show significant associations. T cell responses did not show significant associations with the degree of reactogenicity after the ChAdOx1 vaccination or the BNT162b2 vaccination. Thus, high degree of local reactogenicity after the ChAdOx1 vaccine may be used as an indicator of strong humoral immune responses against SARS-CoV-2.

Lumbar spinal stenosis is a commonly treated with epidural injections of local anesthetics and corticosteroids, however, these therapies may relieve leg pain for weeks to months but do not influence functional status. Furthermore, the majority of patients report no substantial symptom change over the repeated treatment. Utilizing balloon catheters, we successfully treated with three patients who complained persistent symptoms despite repeated conventional steroid injections. Our results suggest that transforaminal decompression using a balloon catheter may have potential in the nonsurgical treatment of spinal stenosis by modifying the underlying pathophysiology.

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.

Many different factors which may affect the prognosis of the soft tissue sarcomas have been reported by many authors ; Generally, tumor size, histologic type, surgical margin, and multi modality therapy therapy as the prognostic factors were reported. The objectives of this retrospective study of soft tissue sarcomas are : 1) to define more clearly prognostic variables that have significant predictive value for disease-free and overall survival ; and 2) to evaluate tumor histologic grade based upon extent of tumor necrosis as a means of stratifying more aggressive soft tissue sarcomas(grade II & III) of the extremities. We treated 94 patients who had soft tissue sarcoma of the extremities and trunk from May 1984 to September 1994(average duration of follow-up was 5 years ranging from 2 months to 10 years) and evaluated the prognostic factors of the soft tissue sarcomas; age, sex, depth, size, location, histologic type and grade, stage, therapy modality, surgical margin, local recurrence and distant metastasis. The results were as follows. 1. The patients with poorer prognosis were over the age of fifty, whose mass was deeply located, size of the mass was over 10cm in diameter, grade III in histology, who had local recurrence, metastasis, and received only surgery. 2. Among these prognostic factors, the most significant prognostic factor was histologic grade base upon extent of tumor necrosis.
