Purpose: The purpose of this study was to evaluate the radiologic features of juxtafacet cyst and determine the correlation between these features and clinical outcome. Materials and Methods: We analyzed a total of 23 patients. The degree of facet joint degeneration was classified using the Fujiwara method. The facet joint angles were measured with an magnetic resonance imaging to determine whether there was a difference between the cystic lesion that was occupied and the cystic lesion that was not occupied. Disc degeneration was measured by the Pfirrmann classification method. The clinical result was evaluated using the Oswestry disability index score and visual analogue scale. Results: The L4-5 level of juxtafacet cyst was mostly affected, as found in previous studies. Facet joint arthritis was more severe within the side with the cystic lesion. Significant correlation was found between disc degeneration and juxtafacet joint cyst. All patients underwent wide decompression and fusion. Clinical result was excellent. No patients had signs of recurrence during the follow-up periods. Conclusion: Juxtafacet cyst has a significant correlation with facet joint degeneration. Therefore, aggressive surgical treatment-not just simple cyst excision-should be considered as the treatment option for juxtafacet cyst associated with degenerative lumbar disease.

Intraductal papillary neoplasm of the bile duct (IPN-B) is a rare disease characterized by multicentric proliferation of adenomatous epithelium within the bile ducts. It has better prognosis because of slow disease progression and high probability of early diagnosis, but also has potential for malignant transformation. Therefore early treatment such as surgical resection has been recommended. There are few reports about nature course of IPN-B without treatment. We report a case of papillary adenoma of intrahepatic duct that transformed into intrahepatic cholangiocarcinoma with 8 years of follow up.

Glycogen storage disease type Ib (GSD Ib) is one of the rare inherited metabolic disease caused by mutation of SLC37A4 gene. Clinical characteristics include hepatomegaly, hypoglycemia, lactic acidosis, hyperlipidemia and high serum uric acid concentration. The authors analyzed clinical and molecular characteristics of three Korean patients (one male and two females) with GSD Ib by retrospective review of medical records. Two patients were diagnosed in toddler period by hypoglycemia and hepatomegaly. One patient was diagnosed by growth retardation and short stature in puberty. c.412T>C (p.Trp138Arg) (3/6 alleles, 50.0%) was most frequently observed, following by p.Leu348Valfs*53 (1 allele), p.Pro191Leu (1 allele), p.Ala148Val (1 allele) in molecular analysis. Uncooked corn starch and allopurinol was administered. Because all three patients had neutropenia and recurrent infections, G-CSF was administered. Two patients had severe osteoporosis needing calcium supplement. The patient who diagnosed at puberty had relatively poor prognosis demonstrated by having severe infection and complications in liver and kidney.

Objectives: Domestic violence is related to many psychiatric diseases, such as depression, anxiety disorder, and PTSD. Heart rate variability (HRV) is an index of autonomic control of the heart and is related to cardiovascular and emotional disorders. Although there have been some studies on the effects of domestic violence on women's mental health, relatively little information is available on HRV in this population. The aim of this study is to investigate demographic data, psychological features, and HRV in female victims of domestic violence and difference between Korean and foreign female victims. Methods: A total of 210 female victims of domestic violence (166 Korean women and 44 foreign women) were recruited for this study. Psychological symptoms were measured using the Hamilton Rating Scale for Anxiety (HAM-A), Hamilton Rating Scale for Depression (HAM-D), and Impact of Event Scale-Revised (IES-R). HRV measures were assessed by time-domain and frequency-domain analyses. Results: The mean score of HAM-A was 13.81, that of HAM-D was 12.92, and that of IES-R was 33.61 ; there were no significant differences between Korean and foreign women in these measures. In HRV time domain analyses, approximate entropy (ApEn) was significantly increased in foreign women compared to the Korean women. The square root of the mean of the sum of the squares of differences between adjacent NN intervals (RMSSD) was significantly decreased in foreign women compared to Korean women. There were no significant differences in the other HRV variables between Korean and foreign women. Conclusion: Female victims of domestic violence in Korea are associated with depression, anxiety, and PTSD symptoms. The physiologic factors of a female victim's nationality could be related to higher ApEn and lower RMSSD in foreign female victims. These findings have important implications for future study to study the relationships among ethnic and environmental factors and HRV variables.

George Canguilhem(1904-1995) is one of the rare French philosophers of the 20th century to develop an approach that was shaped by a medical education. For him, medicine is considered as "a technique or an art at the junction of many different sciences, rather than a proper science." The thesis that medicine is a technique is presented not at a practical level, but on an axiological horizon which reflects the totality of humanity. This character of medicine became a motive that concretized Canguilhem's philosophical thinking. Medical knowledge is not an application of physiology, but is derived from clinical observations which are based on the personal experiences of each patient. If medicine were based on scientific knowledge and its practice the very application of this pure knowledge, the patient might be a passive object. However, the patient doesn't remain passive, but reacts to the menace of disease according to attitude that the patient developed over the course of his or her life. Canguilhem characterizes this point as 'normativity', the core of individual life, which eludes positivist medicine. Here appear the essential contents of his vitalism. Although they emphasized the activity of individual living being, other modern French vitalists didn't consider this dimension of norms. Since the normativity in Canguilhem concerns the subjectivity of the first person, it avoids a mechanical form of explanation. Thus Canguilhem's originality is found in his derivation of the essence of medicine from individuality, values and norms.

Background: Acinetobacter baumannii has emerged as an important nosocomial pathogen worldwide. The incidence of these infections has recently begun to increase. The mortality rate associated with these infections is high (bacteremia; 52%, pneumonia: 23%~73%) and multidrug resistance has been reported. For the effective control of multidrug-resistant Acinetobacter baumannii(MDR-AB), the impact of these organisms in clinical practice should be determined. This study compared the clinical characteristics, mortality and morbidity of Acinetobacter nosocomial pneumonia between MDR strain and non-MDR strain. Methods: From Jan. 1, 2002 to Nov. 1. 2004, 47 adult patients with Acinetobacter nosocomial pneumonia in Chuncheon Sacred Heart Hospital were recruited and analyzed retrospectively. MDR-AB was defined as showing in vitro resistance to all commercially available antibiotics against A. baumannii. Results: There were 47 patients with Acinetobacter nosocomial pneumonia. MDR-AB and non MDR-AB was the cause of the pneumonia in 17 and 30 patients, respectively. Mean age of the former was $69{\pm}11$ years old and the latter was $70{\pm}13$ years old. The mean APCHE II score, ICU days and mortality were not different between the two groups ($16.1{\pm}5.4$ vs. $14.9{\pm}4.8$, P=0.43, $25.1{\pm}13.6$ vs. $39.1{\pm}31.0$, P=0.2, 58.8% vs. 40%, P=0.21). Conclusion: There are no significant differences in mortality and morbidity between MDR and non-MDR Acinetobacter baumannii. The mortality of the two groups is surprisingly high, therefore proper infection control practices are essential.

Bladder cancer is a relatively common cancer type, with a high recurrence rate, that can be often encountered in the imaging study. Accurate diagnosis and staging have a significant impact on determining treatment and evaluating prognosis. Bladder cancer has been evaluated by transurethral resection of bladder tumor for clinical staging and treatment, but it is often understaged when compared with final pathologic result by radical cystectomy. If the location, size, presence of muscle invasion, lymph node metastasis, distant metastasis, and presence of upper urinary tract cancer can be accurately diagnosed and evaluated in an imaging study, it can be treated and managed more appropriately. For an accurate diagnosis, radiologists who evaluate the images must be aware of the characteristics of bladder cancer as well as its types, imaging techniques, and limitations of imaging studies. Recent developments in MRI with functional imaging have improved the quality of bladder imaging and the evaluation of cancer. In addition, the Vesical Imaging Reporting and Data System was published to objectively assess the possibility for muscle invasion of cancer. Radiologists need to know the types of bladder cancer treatment and how to evaluate the changes after treatment. In this article, the characteristics of bladder urothelial carcinoma, various imaging studies, and findings are reviewed.

양성 종양(benign tumor)을 언급하기에 앞서 과오종(hamartoma) 및 과다 형성(hyperplasia)과의 차이를 구분할 필요가 있다. 양성 종양은 기원조직과 유사한 조직이 이상 증식하는 것으로 서서히 성장하지만 일반적으로 치료하기 전까지 이상 증식을 지속하는 진성 신생물을 일컫는다. 이에 비해 과오종은 정상 조직이 무질서하게 과증식하는 것으로 일정기간 후에는 성장을 멈추기 때문에 진성 신생물로 간주하지 않는다. 그러나 일부 과오종이 양성 종양에 포함되기도 하는데, 예를 들어 치아종은 정상적인 치성 조직의 성장이 완료되는 시기와 거의 동일한 시기에 성장을 멈추지만 양성 종양으로 분류된다. 과다 형성은 조직의 세포가 정상적인 배열 양상을 보이면서 세포의 수가 증가하는 것으로 지속적인 성장 양상을 보이지만 그 성장이 제한적이므로 양성 종양과는 구별된다. 양성 종양은 일반적으로 무통성으로 서서히 성장하기 때문에 종양의 크기가 증가하여 안면 종창이나 동통 등을 유발하는 경우에 발견될 수 있으며, 방사선검사에서 우연히 발견되기도 한다. 방사선검사는 병소의 위치, 범위, 특징 및 병소와 인접 해부학적 구조와의 관계 등 많은 방사선학적 진단 정보를 제공한다. 일부 종양은 방사선사진에서 매우 특징적인 소견을 나타내기 때문에 방사선학적 소견으로 예비 진단을 할 수 있을 정도의 진단정보를 제공하기도 하는 반면 어떤 종양들은 방사선사진에서 관찰되는 소견이 매우 유사하여 진단에 어려움을 주기도 한다. 따라서 종양의 확진을 위해서는 생검이 필수적이며, 방사선검사는 반드시 생검에 앞서 진행되어야만 정확한 방사선학적 진단을 할 수 있다. 양성 종양은 각각의 특징적인 방사선학적인 소견을 나타내지만 일반적으로 관찰되는 양성 종양의 특징이 존재하므로 이러한 일반적인 특징을 관찰하여 병소가 양성인지 악성인지를 감별할 수 있다. 첫째, 양성 종양은 대개 호발하는 부위가 있으므로 종양의 발생부위는 감별 진단을 하는 데 매우 중요하다. 일반적으로 치성 병소는 치아가 형성되는 하악관 상방의 치조돌기에서, 혈관성 및 신경성 병소는 하악관 내에서, 연골성 종양은 하악과두와 같이 연골세포가 잔존되어 있는 부위에서 발생하는 경우가 많다. 둘째, 양성 종양은 대체로 명확한 경계와 피질골성 변연을 보이며, 종종 병소가 결체조직으로 둘러싸여 있어 병소 주위에 방사선투과성 띠가 관찰되기도 한다. 셋째, 양성 종양은 일반적으로 인접 주위 조직에 압력을 가하면서 서서히 성장하기 때문에 인접 치아의 변위 또는 흡수, 피질골의 비박, 팽융 등의 소견을 보이며 피질골의 천공은 드물다. 방사선학적으로 양성 종양의 병소 내부는 방사선투과상으로 관찰되거나, 방사선불투과상으로 관찰되거나, 방사선투과상과 방사선불투과상이 혼재된 상으로 관찰된다. 저자는 이 지면에서 이러한 방사선학적 특징을 기초로 하여 구강악안면영역에 발생하는 양성 종양을 분류하고 각각의 특징에 대해 살펴보고자 한다.

Hypophosphatemic rickets is lack of reponse to physiologic doses of vitamin D, different from the vitamin D-dependent rickets. It is inherited in an X-linked dominant fashion. The prime features of this disorder are lowered serum phosphate levels, elevated serum alkaline phosphatase and normal serum calcium levels. The dental manifestation often include apical radiolucencies, abscess and fistulas of clinically sound teeth. Dental radiographs show ricketic bone trabeculations, abscent or abnormal lamina dura and abnormal cementum. This case which was diagnosed to hypophosphatemic rickets, showed multiple spontaneous periapical abscess and gingival fistula enlarged pulp chambers, extension of the pulp horns into the cusp tips and delayed eruption.
