We observed 2 cases of multiple trichoepithelioma, which occured in 25-year- old male and 20-year-old female. They visited our department for multiple skin rashes on the face of 8 years duration in male and 7 years' duration in female patient. Both of them have similar skin lesions characterized by multiplel waxy gshiny, skin colored, firm papules scattered on the nasolabial folds, both eyelids and forehead. Each one of them has a history of similar skin lesions in the family. Literatures are briefly reviewed for discussion of clinical and histopathologicl findings in this disease.

Schizophrenia has been conceptualized as a biologically caused mental disease. However, its causes and pathophysiology have not yet been clearly defined. Unlike physical diseases that are defined using specific biomarkers, mental disorders, such as schizophrenia, are usually diagnosed using the diagnostic criteria established by the consensus of a professional committee. The Diagnostic and Statistical Manual of Mental Disorders (DSM) published by the American Psychiatric Association is widely used as the authoritative guide for the diagnosis of mental disorders, including schizophrenia. If the cause and pathophysiology of a disease are uncertain, a diagnostic concept should be considered valid only when the course, prognosis, or treatment response is generally predictable and consistent. However, patients with schizophrenia who are diagnosed based on the criteria defined by the DSM frequently display varied disease courses and outcomes. This strongly suggests that the current diagnostic concept of schizophrenia in the DSM fails to meet the standards for a valid diagnosis. Although this limitation has been recognized since the DSM-III was published, many psychiatrists today mistakenly believe that the diagnostic concept in the DSM looks at schizophrenia as an explicit disease rather than as a concept. In this review article, we analyze the historical changes in the concepts and diagnostic criteria of schizophrenia. We believe that this will help us to better understand the nature of the current diagnostic approach and also improve our understanding of how the DSM should be used in research and everyday clinical practice.

Transcatheter arterial embolization (TAE) is widely used in the treatment of unresectable hepatocellular carcinoma. Its common complications are right upper quadrant pain, nausea, vomiting, and rare complications include focal pancreatic necrosis, gastric ulcer, renal failure, DIC, biliary tree necrosis and splenic infarction and so on. It has been reported that hepatobronchial fistula could develop as a pleuropulmonary complication of liver abscess. We report a case of hepatobronchial fistula caused by complicating liver abscess in a patient with hepatocellular carcinoma who was treated with TAE.

Objectives: The optimal duration of maintenance treatment for patients with first-episode schizophrenia (FES) remains unclear. We examined the first antipsychotic treatment duration and its association with re-initiation of treatment using a nationwide claim database. Methods: Data from the Health Insurance Review and Assessment Service database in South Korea for 2007–2016 were used. Linear regression analysis and Cox proportional hazard models were used to evaluate the associations between the duration of the first antipsychotic treatment, time to re-initiation of treatment, and occurrence of treatment re-initiation. Results: Of 30,143 patients with FES, 80.4% (n=24,231) received <2 years of the first antipsychotic treatment. In patients who discontinued treatment (n=23,030), the rate of treatment re-initiation was 74.2% (n=17,086). As the duration of the first antipsychotic treatment increased, the time to re-initiation of treatment decreased (β=-0.146, p<0.001); however, the rate of treatment re-initiation was relatively constant (hazard ratio=1.001, p<0.001). Conclusion Long-term antipsychotic treatment was not significantly associated with the rate of treatment re-initiation but showed a negative association with the time to re-initiation of treatment. Further research is needed to better understand the optimal treatment duration for FES.

Objective The aim of this study was to evaluate the clinicopathologic findings of eight patients with primary cancer of fallopian tube diagnosed and treated in the department of Obstetrics and Gynecology, University of Ulsan, Asan Medical Center for nine years. Methods Demographic characteristics, symptoms, signs, stage, tumor grade, mode of therapy and survival of patients were reviewed retrospectively. Results The patients with primary cancer of fallopian tube constituted 0.4% of all gynecologic malignancies encountered during this period. The age of patients ranged 42 to 70 years(mean+/- S.D.; 53.9+/-9.9) and half of patients were postmenopausal and two patients were nulliparous. Patients were treated by simple or radical hysterectomy and bilateral salpingoophorectomy with or without omentectomy and five patients received postoperative chemotherapy. The FIGO surgical stages of the patients were I(4 cases), II(2 cases), III(1 case) and IV(1 case). There were 3 cases of adenocarcinoma, 3 cases of malignant mixed Mullerian tumor, 1 case of undifferentiated carcinoma and 1 case of serous cystic tumor of low malignancy potential. Serum CA 125 values were followed during treatment and decreased during clinical remission and increased at the time of tumor progression. The mean follow-up duration was 24.3(+28.3) months and 7 patients were alive free of disease and one patients with stage Ic died of the disease. Conclusion Primary fallopian tube cancer is an extremely rare malignancy of the female genitalia and preoperative diagnosis of this disease is difficult. Cytoreductive surgery and postoperative combination chemotherapy seem to be effective treatment and CA 125 value could reflect the disease status during the treatment and follow-up of patients.

The intubating laryngeal masK airway is a newly available device designed to allow for blind endotracheal intubation and treatment of patients with difficult airways. Emergency tracheostomies are required for oropharyngeal, hypopharyngeal, and laryngeal tumors acutely obstructing the airway. Patients with an airway obstructive tumor maintain their airway by a very active inspiratory effort in a sitting position. In these patients, it may be impossible to position them for a tracheostomy with shoulder extension. We report a case where a patient was tracheostomized successfully under general anesthesia with blind intubation via ILMA insertion in a sitting position.

PURPOSE: The aim of the present study was to assess the clinicopatholgical significance of Bcl-2 oncoprotein expression in childhood non-Hodgkin's lymphoma (NHL). METHODS: We have assessed 16 cases of childhood NHL during last 6 years from 1990 to 1995. Bcl-2 oncoprotein expression has been semiquantitatively analyzed in paraffin sections from 16 cases of childhood NHL with 39 control cases of adult NHL. The expression of Bcl-2 oncoprotein was correlated with histologic grade, immunophenotype, proliferative activity as measured by immunostain of Ki-67 antigen, clinical stage, and survival rate (event free survival rate, EFS). RESULTS: 1) Bcl-2 oncoprotein expression significantly decreased according to increase of histological grade (P<0.05). 2) High Bcl-2 oncoprotein expression was more frequent in B-cell NHL than T-cell NHL (P<0.05). 3) Proliferative activity as measured by immunostain of Ki-67 antigen was negatively correlated with Bcl-2 oncoprotein expression (P<0.05). 4) Bcl-2 oncoprotein expression was not correlated with clinical stage (P>0.05). 5) EFS of patients was significantly correlated with Bcl-2 oncoprotein expression, that is, reduced EFS was demonstrated in the patients with low Bcl-2 oncoprotein expression (P<0.05). CONCLUSIONS: Thus Bcl-2 oncoprotein, as demonstrated immunohistochemically in routinely paraffin embedded tissue, can be restrictively used in prediction of prognosis and grade of childhood NHL, in aggrement with the role of Bcl-2 oncoprotein in blocking of apoptosis and indirect contribution to increase of cellular proliferative activity of NHL.

OBJECTIVES: Several studies have delineated the relationship between hearing disturbances and the prevalence or characteristics of psychotic symptoms; however, most of those studies focused on psychiatric patients and not general inpatients. Delirium has a high incidence among general inpatients, and patients with delirium are easily affected by psychotic symptoms that lead to irritable behaviors. This study examined the relationship between hearing disturbance and psychotic symptoms among patients with delirium. METHODS: At the Asan Medical Center in Seoul, South Korea, this study examined 27 inpatients who had both delirium and hearing disturbances between January 1, 2009 and December 31, 2018, and 146 inpatients at the Asan Medical Center who had delirium but no hearing disturbances between July 1, 2018 and December 31, 2018. This study investigated whether the two groups showed differences in the prevalence and characteristics of delirium symptoms, particularly psychotic symptoms. In addition, the correlation between clinical characteristics of delirium and the recommended dosage of antipsychotics was analyzed in patients who had been diagnosed with delirium and had hearing disturbances. RESULTS: Compared to inpatients who only had delirium, those who had both delirium and hearing disturbances had a significantly higher prevalence of hallucination and delusion. CONCLUSION: The prevalence of psychotic symptoms, such as hallucination and delusion, was higher in patients who had both delirium and hearing disturbances, which is in line with the results from previous studies on psychiatric patients. Physicians should focus on improving communication with such patients by employing non-verbal communication methods.

PURPOSE: To assess the clinical characteristics and surgical approaches in different anatomical and hemodynamic types of corrected transposition of great arteries(TGA) and learn the surgical results of those patients. METHODS: All 52 patients who were diagnosed as corrected TGA between December 1987 and November 1999 and their medical records were reviewed. Three groups were identified according to associated anomalies', Group 1: TGA with intact ventricular septum(n=7), Group 2: TGA with ventricular septal defect(n=6), Group 3: TGA with ventricular septal defect and pulmonary stenosis(n=39). RESULTS: The clinical manifestations and managements according to associated anomalies were different. The average ages at operation were 190, 8.8 and 47 months in Groups 1, 2, and 3, respectively. The five patients underwent double switch operation and the remainder were managed conventionally without correcting discordant connection. Four patients died and 5 patients were re-operated. Eleven patients developed complete heart block, and 7 of them had permanent pacemakers. Progressive systemic tricuspid valve regurgitation developed in 15 patients and progressive systemic right ventricle dysfunction developed in 3 patients. CONCLUSION: The results of conventional management were disappointing, with significant morbidity of tricuspid failure, right ventricle failure and conduction system failure. Anatomical repair of corrected TGA can be achieved with favorable immediate surgical results but long-term follow up will be necessary.

PURPOSE: Congenital mitral stenosis(CMS) is a rare anomaly accounting for 0.4-0.5% of total heart disease. CMS which cases needed surgical correction in infancy are even rare. In this study, we analyzed 11CMS patients of less than 2 year of age who needed surgical corrections, in order to find out their diagnoses, the characteristics, the results of operation and prognoses, and the progress of disease without surgical correction. METHODS: Retrospective studies were performed on eleven CMS patients of less than 2 years of age admitted to Sejong General Hospital between Jan. 1989 and Aug. 1999. RESULTS: The surgeries were performed on 9 out of 11 enrolled patients. The median age was 8(3-20) months and the median weight was 5(4-9)kg. The mitral valves of the patients were classified anatomically as supramitral ring(4), parachute mitral valve(3), "typical" symmetric hypoplastic mitral valve(2) and asymmetric hypoplastic mitral valve(2). Three patients died after the surgical correction. Among them, fibroelastosis of left ventricle was found during the surgery in two cases, and the other case was considered to be in Eisenmenger state. 5. Reoperations were performed on 3 out of 6 surviving patients. While one case was an early reoperation, two case were late ones. CONCLUSION: The patients with severe CMS under the age of two can be surgically corrected with an acceptable success rate. Poor results were observed, however, if the decisions for surgical intervention were delayed.
