As a postoperative complication, the recurrence of aural cholesteatoma is well documented. On rare occasions, a recurred cholesteatoma can penetrate the adjacent soft tissues instead of middle ear or extemal auditory canal. Recently, authors experienced a cholesteatoma in soft tissues of posteriorinferior portion of auricle, developing 8 years after an intact bridge mastoidectomy. We reviewed the reported case of cholesteatoma in soft tissues.

A benign fibrous histiocytoma is a tumor with 6brohlastic and histiocytic differentiation, most commonly found in soft tissues or adult bones. Its occurrence in the ear is, however, extremely rare, and there hasn't been any report on the case originating from the middle ear. We experienced a case of 37-year old male patient who complained of intermittent otorrhea and hearing loss. The patient had an 1 x 1 cm-sized mass in the right mastoid antrum in the temporal bone CT. Under the impression of cholesteatoma or benign tumor, a mass removal was done. A histopathologic investigation of the resected tumor showed typical features of benign fibrous histiocytoma. We herein report along with a brief literature review a case of benign fibrous histiocytoma arising in the mastoid antrum.

OBJECTIVES: This study compared attitudes toward antipsychotic treatment according to awareness of the name of their illness in patients with schizophrenia. METHODS: Information on sociodemographic and clinical characteristics, including awareness of the importance of antipsychotic treatment, was obtained through a self-report questionnaire. The Drug Attitude Inventory (DAI) was administered. The data were compared according to awareness of the name of their illness. RESULTS: The study analyzed data for 199 patients with schizophrenia. Of these, 115 patients (57.8%) were aware that their illness was called schizophrenia, while 84 patients (42.2%) knew it by their psychotic symptoms or as another mental illness, such as depression. The patients aware of the name of their illness had significantly longer durations of illness and higher scores on the DAI. They were significantly more likely to have stopped taking medication on their own accord and to agree with the importance of antipsychotic treatment. Statistical significance was sustained in a logistic regression analysis after adjusting for the duration of illness and study site, except for the DAI score, which had borderline significance (p=0.055). In subjects with duration of illness > or =5 years, patients aware of the name of their illness had significantly higher scores on the DAI. CONCLUSION: Awareness of the name of their illness was associated with awareness of the importance of, and a positive attitude toward, antipsychotic treatments in patients. Psycho-education, including telling the patient the correct name of his or her illness, might be needed for maintaining antipsychotic treatment in patients with chronic schizophrenia.

This study was designed to evaluate the potential applications of magnetic resonance imaging for the diagnosis of early and sequential changes of acute renal ischemia. Renal isehmia was induced in seventeen rabbits by surgical ligation of the left renal artery. Magnetic resonance imaging(MRI) was performed with a 2.0T super conductive MR system and s pin-echo technique was used with echo times(TE) of 30 and 80 msec and repetition times(TR) or 0.5 and 2.5 seconds. Kidneys were evaluated before and up to 48 hours after left renal artery ligation, and the spin echo images were analyzed for intensity difference and T1, T2 relaxation times between the cortex and the medulla of both kidneys. After one, and one and half hour following ligation of the left renal artery, the kidneys showed a 4-20% decrease in the left cortex compared to the right cortex contrast uptake(CCC) (P<01). There was a 14-29% decrease in left medulla to right medulla contrast uptake(MMC) (P<01). A 29-147% increase in contrast uptake was noted when the left cortex was compared to the left medulla(P<05). There was a 51-68% decrease in CMC of the right kidney (P<05) on three different spin echo images. In the cortex of the left kidney, T2 relaxation time decreased 14% (P<01). CCC and MMC showed more prominent changes than CMC, and sequential changes of CCC and MMC were most prominent on T2 weighted images with TR = 2.5sec and TE=80msec when compared with T1 weighted and proton density weighted images. Twelve hours after renal arterial ligation. T2 relaxation time, CMC, CCC, and MMC returned to normal values and these findings were believed to be due to congestion and collateral blood supply. In renal ischemia, the most useful MRI findings for diagnosis were fund to be changes of CCC and MMC on T2 weighted image, and T2 relaxation time of the cortex in the ischemic kidney.

A chylous fistula has been reported to occur in 1% to 2% of cases as a complication of neck dissections, but a bilateral chylothorax following neck dissection, without concurrent chylous leakage at operation site, was very rare. In the chylothorax, serious problems may occur in cardiopulmonary function, metabolism, and nutrition of patient. Early diagnosis and proper management is very important. Recently authors experienced a case of bilateral chylothorax following neck dissection and managed with conservative treatment.

OBJECTIVES: This article aims to describe the development of smartphone application for the case management of patients with schizophrenia. METHODS: Gwangju Bukgu-Community Mental Health Center developed and launched a smartphone application (HYM) for cognitive-behavioral case management and symptom monitoring. The development of the application involved psychiatrists, nurses, social workers, psychologists, and software technicians from a software development company (Goosl Corp.). RESULTS: The HYM application for clients includes six main modules including Thought record, Symptom record, Daily life record, Official notices, Communication, and Scales. The key module is the 'Thought Record' for self-directed cognitive-behavioral treatment (CBT). When the client writes and sends the self-CBT sheet to the case manager, the latter receives a notification and can provide feedback in real time. 'Communication' and 'Official notices' are useful for promoting communication between case managers and clients with schizophrenia. Ratings in 'Symptom record', 'Daily life record', and 'Scales' modules are stored in graphic or table form representing changes in them and shared with case managers. CONCLUSION: The interactive function of this application is the key characteristics that distinguishes it from other mobile self-treatment tools. This smartphone application may contribute to the development of a youth- and customer-friendly case management system for individuals with early psychosis.

Until 1972, many carcinoid tumors of the thymus were not recognized as distinct lesions and were mistakenly labeled as variants of thymomas. Thymic carcinoid tumors are unusual neoplasms that show different morphological, functional, and behavioral characteristics than those of thymomas. We report a case of a 65-year-old woman with thymic carcinoid tumor. The cinicopathological findings are discussed with a review of the literature.

BACKGROUND AND OBJECTIVES: Both carotid intima-media thickness (CIMT) and carotid plaque are important factors in the primary prevention of cardiac disease. However, it is unclear which one is more important for prognosis, especially in patients with coronary artery disease (CAD). SUBJECTS AND METHODS: In total, 1426 consecutive CAD patients, proven by angiography, were followed-up for a mean of 85 months. The study population was divided into four groups depending on the CIMT (> or =0.83 mm, >95 percentile in Korea) and the presence or absence of carotid plaque. RESULTS: Patients with carotid plaque and thick CIMT (n=237, 16.6%) had a higher prevalence of hypertension, diabetes mellitus, and dyslipidemia than those had plaque and thin CIMT (n=213, 14.9%), those without plaque and thick CIMT (n=265, 18.6%) and those without plaque and thin CIMT (n=711, 49.9%). The patients with carotid plaque and thick CIMT group had a higher cardiac mortality rate (20.7% vs. 13.1%, 9.4% and 3.9%, respectively, p<0.001) and higher major adverse cardiovascular events (MACE) including death, acute myocardial infarction, and stroke (27.8% vs. 18.8%, 15.5% and 9.3%, respectively, p<0.001) than any other groups. Multivariate Cox regression analysis showed that the presence of carotid plaque with thick CIMT had the highest hazard ratio (HR) compared to other groups (HR 2.23 vs. 1.81, 2.01) for cardiac mortality. Also, carotid plaque had a higher HR than CIMT for mortality (HR 1.56 vs. 1.37) and MACE (HR 1.54 vs. 1.36) in the total study population. CONCLUSION: Carotid plaque is a more important prognostic factor than CIMT in patients with CAD, and adding a thick CIMT to carotid plaque increases the prognostic power for cardiac events.
