PURPOSE: Delirium in the elderly is common in the postoperative period but there are only few reports on detailed studies of this condition. Number of urologic patients with postoperative delirium was increas ed in our hospital for recent 24 months. The clinical characteristics of patients with postoperative delirium was analyzed retrospectively. MATERIALS AND METHODS: We selected the patients with postoperative delirium from 1010 patients who had undergone urological surgery under general or spinal anesthesia in the period from Jan. 1997 to Dec. 1999. Diagnosis of postoperative delirium was established with Diagnostic and Statistical Manual of Mental Disorders(DAM-III-R) by psychiatric clinicians. Onset and recovery of symptoms, risk factors, previous psychiatric clinicians. Onset and recovery of symptoms, risk factors, previous psychiatric disorder, relationship with anesthesia, drugs, and surgical procedures, concomittant medical conditions, and complications were retrospectively reviewed. RESULTS: Postoperative delirium was observed in 13 patients (1.3%). All patients were male and mean age was 70.4 years (46-86 years). Surgical procedures included TURP(8 patients), cystectomy (3 patients), nephroureterectomy (1 patient), and bladder rupture repair (1 patient). Delirium became apparent between one day and two days after the operation (mean 32.2 hours) and lasted for up to 7 days (mean 53 hours). Several factors such as older age (>65 years), male patient, longterm medication, past history of CVA, memory impairment, hearing difficulty, traumatic brain contusion, and obsessive personality were thought to be risk factors of postoperative delirium. Treatment with Haloperidol(R) intramuscular injection (2.5-5mg, every 30 minutes, 2-4 times until symptom resolution was achieved) with or without Ativan(R) intravenous injection (2mg) were effective. Complete symptom recovery was seen in 92.3% (12/13) of patients. One patient (7.7%) with previous history of dementia had persistent memory disturbance and disorientation during follow-up periods. CONCLUSIONS: Generally, postoperative delirium is an acute transient confusional state without considerable sequeles. Treatment is sedation and prevention of inadvertent accident associated with confusional state. Urologic surgeon must be attentive to the development of this illness especially when high risk factors were present.

We present 20 medicolegal autopsies performed at the Department of Forensic medicine, Seoul National University Medical College during the year of 1996. In Korea Postmortem Invesigation (PI) system is not established and is needed greatly provide the basic considerations on PI system, we detailed the cases with impediments to be overcome. Among the 20 cases, 13cases were unusual deaths and 6 cases were natural. For unusual deaths, 7 were by mechanical injuries, four by asphyxia. Test for toxic stance was the most needed part to be solved.

Korean Journal of Legal Medicine 1999;23(1):35-42
This treatise summarizes the medical facts about the persistent vegetative state(PVS) and the associated issues. In August 1998, the opinions of the 380 neurologists and the 1007 neurosurgeons are inquired about the diagnostic criteria of PVS, the degree and the withdrawal of treatment on PVS patients. The response rate is 18.8%. The diagnostic criteria of PVS is determined by the items approved above 5007o of responses. (1) no evidence of cerebral function and an inability to interact with visual, auditory stimuli and follow commands. (2) maintaining the respiratory function with spontaneous respiration and normal respiratory pattern. (3) spontaneous eye opening and eye ball movements without sustained tracking. (4) variably preserved brain stem reflexes. (5) presence of sleep-wake cycles. (6) (1)-(5) symptoms should be persist for 6 months after the development of vegetative state. (7) the diagnostic criteria of PVS should be applied more than 3 times during the minimum observation period. (8) this diagnostic criteria of PVS could be applied to adults over 7 ages. As to the degree of treatment, nasogastric tube feeding and air-way keeping through the tracheostomy are approved over 9007b. Also antibiotics can be used in infection. As to the withdrawal of treatment, do not resuscitate order of patient s family is accepted by 46.1% in an emergency condition like cardiac arrest. But discharge against medical advice by the patient s family is accepted by 73.107o in non-emergency condition. In the case of neonates, parents decision is more determinative than any other thing.

We present two cases of adrenocortical oncocytomas that were well-delineated on multi-detector computed tomography and magnetic resonance imaging. The images showed a well-enhanced large mass with multiple stippled calcifications in a 10-yr-old girl who was consulted due to precocious puberty. A well-enhanced solid mass with necrotic components was incidentally noticed in a 54-yr-old man. These lesions were resected and diagnosed as adrenocortical oncocytomas through immunohistochemical studies and electron microscopy. Adrenocortical oncocytomas are rare disease entities, therefore, we report these interesting, rare adrenocortical oncocytomas here with radiologic findings, and discuss differential diagnosis.

Background:
The Advanced RBC Application of the CellaVision DM9600 system (CellaVision AB, Lund, Sweden) automatically characterizes and classifies red blood cells (RBCs) into 21 morphological categories based on their size, color, shape, and inclusions. We evaluated the diagnostic performance of the CellaVision Advanced RBC Application with respect to the classification and grading of RBC morphological abnormalities in accordance with the 2015 International Council for Standardization in Haematology (ICSH) guidelines.
Methods:
A total of 223 samples, including 123 with RBC morphological abnormalities and 100 from healthy controls, were included. Seven RBC morphological abnormalities and their grading obtained with CellaVision DM9600 pre- and post-classification were compared with the results obtained using manual microscopic examination. The grading cut-off percentages were determined in accordance with the 2015 ICSH guidelines. The sensitivity and specificity of the CellaVision DM9600 system were evaluated using the manual microscopic examination results as a true positive.
Results:
In pre-classification, > 90% sensitivity was observed for target cells, tear drop cells, and schistocytes, while > 90% specificity was observed for acanthocytes, spherocytes, target cells, and tear drop cells. In post-classification, the detection sensitivity and specificity of most RBC morphological abnormalities increased, except for schistocytes (sensitivity) and acanthocytes (specificity). The grade agreement rates ranged from 35.9% (echinocytes) to 89.7% (spherocytes) in pre-classification and from 46.2% (echinocytes) to 90.1% (spherocytes) in post-classification. The agreement rate of samples with withinone grade difference exceeded 90% in most categories, except for schistocytes and echinocytes.
Conclusions
The Advanced RBC Application of CellaVision DM9600 is a valuable screening tool for detecting RBC morphological abnormalities.

To know the prevalence of the diabetes mellitus and associated diseases, we analyzed the date of the 3,088 subjects who were examined with the Computed Automated Medi-Screening Test System which consisted of 65 parameters including blood glucose determination fasting and one hour after 100 g of oral glucose load. We grouped the subjects by the modified criteria of National Diabetic Data Group. Followings are the results of the various analysis: 1. The prevalence of diabetes mellitus and impaired glucose tolerance in 2.27% and 18.26% respectively. 2. The prevalence of diabetes mellitus is 2.63% in male and 1.66% in female. There is no statistically significant difference between male and female. 3. There in tendency of increasing prevalence of diabetes mellitus as the age increases. From second to eighth decade, the prevalence of diabetes mellitus increases as 0.0, 0.45, 0.67, 2.28, 3.47, 5.36, 10.00% respectively. 4. There is no statistically significant difference of prevalence of obesity between normal and diabetes: that is, 18.03%, 22.86% respectively (P≥0.1). 5. There is no statistically significant difference of prevalence of impaired glucose tolerance and diabetes between non-obese and obses group (P≥0.1). 6. There is statistically significant increases of frequency of proteinuria, azotemia, hypertension as the glucose tolerance decreases (P≤0.05).

Actinomycosis, in which the principal causative agent in man is known to Actinomyces israelii, is a chronic, suppurative diseases characterized by extensive fibrosis, multiple abscesses, and formation of sinus tracts that drain suppurative exudates. On the basis of the anatomical sites involved; it can be subclassified into the cervicofacial form, which is the most common form, pulmonary form and abdominal form. Kidneys are rarely affected. Clinically, radiologically, and at operation it is difficult to differentiate the renal actinomycosis from renal tuberculosis and renal carcinoma. The prognosis is excellent after nephrectomy followed by appropriate antibiotic therapy. We presented a case of renal actinomycosis with a brief review of the literatures.

In order to evaluate antitumor rnechanisms of interleukin (IL)-12/IL-2 that has been shown significant tumor suppressive activity on established primary and metastatic Renca tumor, we studied chemokine gene expression induced by direct action of IL- 12/IL-2 or cytokine cascade. IL-12/IL-2 induced gene expression of interferon gamma (IFN-r) and granulocyte monocyte-colony stimulating factor (GM-CSF) in splenocytes, and it induced gene expression of monokine induced by IFN-r (Mig), interferon inducible protein 10 (IP- 10), SDF-1, macrophage inflammatory protein (MIP)-1a, MIP-1B, MIP-2, monocyte chemotactic protein (MCP)-1, and Rantes in tumor mass. However IL-12/IL-2 could not induce these chemokines in tumor mass of GKO mice and Renca cell in vitro. IL- 12 also did not increased chemokine gene expression in Renca cell in vitro, but IFN-r induced gene expression of Mig, IP-10, MCP-1 in Renca cell in vitro. In the chemotaxis assay, culture supernatant of Renca cell stimulated with IFN-r increased splenocyte migration in vitro. All these data suggest IL-12/IL-2 can induce IFN-r-chemokine cascade in tumor mass, and Mig, IP-10, MCP-1 produced from tumor cell may play an important role for initial immune cell migration into tumor mass.
