A 17-year-old spayed female Shih Tzu dog, weighing 5.0 kg, presented with frequent coughing and respiratory distress. Blood tests revealed mild thrombocytosis, and thoracic ultra-sonography and radiography confirmed a significant amount of pleural effusion. However,the thoracic radiographs showed no radiopaque nodules or interstitial patterns indicative ofthoracic tumors. Thoracentesis was performed to relieve effusion-induced thoracic pressure, yielding a hemorrhagic serosanguinous pleural fluid. The cytological analysis of this fluid re-vealed mesothelial cells, supporting the clinical diagnosis of mesothelioma in situ. To address the patient’s clinical symptoms, an aggressive management approach was implemented withchest tube placement to address recurrent pleural effusion after initial thoracentesis. Duringtreatment, the patient exhibited stable health and adapted well to daily life. To the best of our knowledge, this is the first reported case of mesothelioma in situ with hemorrhagic malignant pleural effusion in South Korea. Using a chest tube as an aggressive treatment successfullyalleviated dyspnea symptoms and provided symptomatic relief in a patient with mesothelioma in situ.

4.Concept of Countertransference.
Journal of Korean Neuropsychiatric Association 2016;55(4):321-333
Freud originally defined countertransference as “a result of the patient’s influence on (the analyst’s) unconscious feelings.” The result of uncontrolled countertransference is a loss of analytic neutrality. Beginning circa 1950, the literature on countertransference reflected an increasing awareness of the clinical importance of the phenomenon, and there was a significant expansion of the meaning of the term beyond that in Freud’s original definition. Moreover, many clinicians began dealing with countertransference as a tool for understanding the analysand. In the 1980s and 1990s, countertransference emerged as an area of common ground among psychoanalysts with diverse theoretical perspectives. This convergence can be traced to the development of two key concepts– projective identification and countertransference enactment. Within the intersubjectivity theory, countertransference is an amalgam of the therapist’s response to therapeutic reality with the influence of past experiences on the immediate responses of both patient and therapist. Currently, although there are many differences among the diverse theoretical schools of psychoanalytic thought, there is an area of convergence regarding the usefulness of countertransference in understanding the analysand. In addition, there is widespread acknowledgement that an inevitable aspect of analysis is that a patient will treat the analyst as a transference object. Moreover, the analyst’s countertransference reaction is a joint creation that includes contributions from both patient and analyst.

5.Stereotactic Cardiac Radiation to Control Ventricular Tachycardia and Fibrillation Storm in a Patient with Apical Hypertrophic Cardiomyopathy at Burnout Stage: Case Report

Journal of Korean Medical Science 2020;35(27):e200-
Stereotactic cardiac radiation for ablation (radioablation) of life-threatening ventricular arrhythmia was recently introduced into clinical practice. A 76-year-old male patient with apical hypertrophic cardiomyopathy at burnout stage, who received defibrillator implantation for the secondary prevention of sudden arrhythmic death, was admitted for repeated defibrillator therapy. Radiofrequency catheter ablation was unsuccessful due to the induction of ventricular fibrillation (VF) and hemodynamically unstable sustained monomorphic ventricular tachycardia (VT). However, intracardiac activation mapping for the induced VT revealed the earliest ventricular activation at the apical aneurysm. Radioablation was performed to control VT and VF storm refractory to antiarrhythmic drug therapy. A total of 24 Gray was radiated, divided into three fractions around the apical aneurysm. The onset of electrical modulation was instantaneous and the antiarrhythmic effect was maintained for at least 6 months without significant radiation toxicities. This case suggests that radioablation may be considered as a rescue therapy for VT and VF storm refractory to other treatment modalities.

Even though uroplakins (UPs) are believed to serve a strong protective barrier against toxic materials, cyclophosphamide (CP) causes extensive cystitis. We investigated the expression of UPs in the urothelium in CP induced mouse cystitis. A total of 27 ICR female mice received a single intraperitoneal injection of 200 mg CP/kg. Nine CP-treated mice and 6 controls were sequentially killed at 12, 24, and 72 hr post injection. Extensive cystitis and an increased vesical weight were seen. These all peaked within 12 hr post injection and they tended to decrease thereafter. The level of all the UPs mRNA, the protein expressions of UP II and III on immunoblotting study, and the expression of UP III on immunolocalization study were maximally suppressed within 12 hr; this partially recovered at 24 hr, and this completely recovered at 72 hr post CP injection. In conclusion, CP reduced the expression of UPs. The reduction of the UPs mRNA and protein was time dependent, and this peaked within 12 hr after CP injection. However, the damage was rapidly repaired within 24 hr. This study demonstrates a dynamic process, an extensive reduction and rapid recovery, for the UPs expression of the mouse urinary bladder after CP injection.

OBJECTIVE: We performed a cross-sectional study to examine the relationship between premorbid personality and behavioral and psychological symptoms in dementia (BPSD) in Korean patients with Alzheimer's disease (AD). METHODS: We assessed 103 patients diagnosed with AD for the presence of BPSD over the disease course by using the caregiver-rated Korean version of the Neuropsychiatric Inventory (K-NPI) and for the premorbid personality by using a retrospective version of the NEO-Five Factor Inventory questionnaire completed by informants. RESULTS: Premorbid neuroticism was significantly correlated with delusion, agitation, anxiety, disinhibition, total K-NPI score (p<0.05), and sleep disturbances (p<0.01). Lower premorbid conscientiousness was significantly correlated with symptoms of hallucinations and sleep disturbances in AD patients (p<0.05). However, premorbid neuroticism and low premorbid conscientiousness did not act as independent predictors for "psychosis, hyperactivity," or "moods, apathy, frontal" factors of BPSD. CONCLUSION: Premorbid personality was associated with the K-NPI score, but was not observed to be potential predictors of BPSD.

8.Optimal Radiation Therapy Field for Malignant Astrocytoma and Glioblastoma Multiforme.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2002;20(3):199-205
PURPOSE: This study was performed to determine the optimal radiation therapy field for the treatment of malignant astrocytoma and glioblastoma multiforme. MATERIALS AND METHODS: From Jan. 1994 to Mar. 2000, 21 patients with malignant astrocytoma and glioblastoma multiforme, confirmed as recurrent by follow up MRI after surgery and radiation therapy, were analyzed. The distance from the margin of the primary lesion to the recurrent lesion was measured. The following factors were analyzed to investigate the influence of these factors to recurrence pattern; tumor size, degree of edema, surgical extent, gamma knife radiosurgery and multiple lesions. RESULTS: Among the 21 patients, 18 (86%) were recurred within 2 cm from the primary lesion site. 12 within 1 cm, 6 between 1 and 2 cm. The other 3 patients all with multiple lesions, were recurred at 3, 4, 5 cm, from the primary lesion site. The recurrence pattern was not influenced by the factors of tumor size, extent of edema, surgical extent, or gamma knife radiosurgery. However, patients with multiple lesions showed a tendency of recurrence at sites further from the primary lesion. CONCLUSIONS: Most (86%) of the recurrences of malignant astrocytoma and glioblastoma multiforme occurred within 2 cm from the primary lesion site. The width of treatment field does not need to be changed according to tumor size, degree of edema, surgical extent, or gamma knife radiosurgery. However, the treatment field for multiple lesions appears to be wider than that for a single lesion.

Acute appendicitis is very rare in premature neonates. Preoperative diagnosis of this condition is difficult, and then it leads to high morbidity and mortality. We report 9-day-old premature male with ruptured acute appendicitis presented with pneumoperitoneum on plain films of the abdomen. Awareness of this rare condition and possible differential diagnosis in this age group is also discussed.

Journal of Korean Geriatric Psychiatry 2002;6(2):110-116
OBJECTIVE: This study was designed to evaluate the cause of mortality in patients with dementia, including Alzheimer's disease and multi-infarct dementia, and those without dementia. METHOD: Hospital records of geriatric patients (> or =65) in nursing home having dementia were reviewed retrospectively for 6 years. The total number of patients was 351 (the number of demented patients was 146 and those without dementia was 68). Of the ones with dementia, 146 had dementia of Alzheimer's type, 101 patients had vascular dementia, and 36 patients had non-specific dementia. This study focused on the different complications associated with Alzheimer's disease and cerebrovascular dementia. RESULT: 1) The average age at death of demented patient is higher than the non-demented population;however, there is no difference in age between Alzheimer's disease and vascular dementia. 2) There is no difference in time spent in the nursing home among the non-demented group, Alzheimer's disease and vascular dementia group from admission to death. The life expectancy of male patients with Alzheimer's disease after admission to the nursing home is significant shorter than their female counterpart. 3) Patients with vascular dementia have a higher incidence of hypertension, atherosclerotic disease, and diabetes than the Alzheimer's patients. 4) The main overall causes of the death (in nursing home patients) are infection and sepsis. In Alzheimer's disease's, sepsis is the major cause of death, while in vascular dementia, atherosclerotic disease is the number one cause. CONCLUSION: Knowledge of the causes of the death in demented patients may help the management of the possible complications associated with the different types of dementia. However, long-term research is then needed to analyze the survival rates of demented nursing home patients.
