1.Histologic Estimation of Intrauterine Retention Time after Fetal Death.
Korean Journal of Legal Medicine 2013;37(4):191-197
The intrauterine retention time (IURT) after fetal death can be estimated from the loss of nuclear basophilia. We therefore attempted to derive an autolysis equation to estimate IURT in experimental rat fetuses and human fetal autopsy slides. The degree of loss of nuclear basophilia in various tissues was assessed by hematoxylin and eosin (H & E) staining. Fetal rat tissues showed different rates of autolysis, allowing for the construction of an experimental autolysis curve. We also reviewed the H & E stained slides obtained from 27 human fetal autopsy cases with well-documented death intervals. The degree of autolysis in various tissues was evaluated using percentile scores (PS). Using the findings from H&E staining, we derived the equation Ln (PS/[100-PS]) = 2.62716-0.02377 x IURT. However, this equation or autolysis scores showed some limitations. Owing to the inconsistency of PS, this equation is reliably applicable only within 24 hours of intrauterine fetal death. In the fetal autopsy review, fetal hydrops, local effusion, and sepsis also contributed to accelerated autolysis.

2.Arthroscopic Excision of Intra-articular Osteochondroma of the Elbow: A Case Report.
Clinics in Shoulder and Elbow 2016;19(3):172-175
Osteochondromas are one of the most common benign bone tumors usually involving extraarticular metaphysis of long bone. Solitary intra-articular osteochondroma arising from the elbow joint has rarely been reported. We present a case of 23-year-old female who had pain and limited motion of the left elbow as a result of intraarticular osteochondroma of the distal humerus. Arthroscopic excision of the osteochondroma yielded complete relief of symptoms. Absence of recurrence was confirmed radiographically at two years after surgery. To the best of our knowledge, this is the first report of osteochondroma of the elbow successfully treated arthroscopically.

3.The pathogenic mechanisms of motor weakness following aneurysmal subarachnoid hemorrhage: A review
Neurology Asia 2017;22(3):185-191
Motor weakness is one of the neurological complication that can occur after aneurysmal subarachnoid
hemorrhage (SAH); incidence of motor weakness of 14~29% has been reported. Detailed information
on the pathogenic mechanism of motor weakness is essential for brain rehabilitation because it enables
estimation of the severity of injury, establishment of scientific rehabilitative strategies, and prediction
of motor outcomes by clinicians. However, the exact pathogenic mechanisms of motor weakness
following aneurysmal SAH have not been clearly elucidated. In this article, 14 previous studies on
pathogenic mechanisms in patients with aneurysmal SAH were reviewed according to the location of
the lesion (cerebral cortex, brainstem, spinal cord, and peripheral nerve). The following pathogenic
mechanisms have been suggested: vasospasm, cerebral ischemia, hydrocephalus, compression of
cerebral cortex, neural injury, spinal cord infarction, and radiculo-neuropathy. Considering the high
incidence of aneurysmal SAH and motor weakness following aneurysmal SAH, we believe that the
pathogenic mechanisms of motor weakness have been relatively understudied. More effort should be
taken to investigate this important topic.

6.Experience of Double J Stents on Urinary Diversion.
Korean Journal of Urology 1987;28(6):881-886
Double J stents have been advocated for drainage or splintage of the ureter. Fifty-four attempts at double J stent insertion were made in 46 patients. In 93% attempts the stent was satisfactorily placed. Their use in adjunct to urologic and gynecologic surgery, percutaneous nephrolithotomy and ureterorenoscopy has been encouraging but poor results have been obtained in patients with ureteral obstruction due to tuberculosis and malignancy.

PURPOSE: We compared the clinical manifestations of patients with tsutsugamushi disease between children and adults. METHODS: From January 2003 to December 2012, 768 patients diagnosed with tsutsugamushi disease were retrospectively reviewed, and the clinical characteristics, laboratory findings, and complications were compared between children and adults. RESULTS: No patterns of annual increases in the number of patients were noted in both children and adults. The higher incidences occurred in October and November respectively. By gender, male outnumbered female in children, but the opposite trend was seen in adults. By residential area, the urban distribution of children was higher than that of adults. Rashes (P=0.001) and eschar (P=0.004) were more common in children, while myalgia was more common in adults. Children had a high prevalence of anemia (P=0.041), and low incidence rates of thrombocytopenia, abnormal liver and renal function. Children yielded better results in the duration of their hospital stay and the incidence of complications (P<0.001). A comparison of the therapeutic effects of doxycycline and macrolide antibiotics, which was performed only on the children, did not reveal any significant differences. CONCLUSION: Compared to adults, children had higher incidence rates of male patients and more often suffered from rashes and eschar. Children yielded better results in the laboratory findings and duration of the hospital stay and complications. Therefore, when children are suspected to have tsutsugamushi disease, especially during its peak occurrence period, detailed physical examination and serological test should be performed to ensure a prompt diagnosis, and the use of macrolide antibiotics, which have fewer side effects, is expected to yield the same therapeutic effects.

BACKGROUND: Few studies have reported the results of arthroscopic coracoplasty concomitantly conducted with subscapularis tear. Therefore, this study was conducted to examine and compare the outcomes of arthroscopic subscapularis repair after arthroscopic coracoplasty using either the subacromial approach or rotator interval approach. METHODS: We retrospectively reviewed 51 patients who underwent coracoplasty with subscapularis repair. The patients were grouped according to whether the subacromial approach group (24 patients) or rotator interval approach group (27 patients) was used during coracoplasty. Preoperative and postoperative visual analogue scale scores, American shoulder and elbow surgeons scores, Korean shoulder scores, and range of motion (ROM) were assessed. Assessment of repaired rotator cuff tendon integrity was performed at 1 year after surgery using either magnetic resonance imaging or ultrasonography. RESULTS: At final follow-up, overall functional scores and ROM improved significantly in both groups when compared with preoperative values (p>0.05). The re-tear rates were not significantly different between groups; however, the rotator interval approach group showed a significant increase in ROM compared with that in the subacromial approach group (p<0.05). CONCLUSIONS: Arthroscopic coracoplasty conducted concomitantly with subscapularis repair can provide a satisfactory outcome. There were no significant differences between the two approach groups regarding final functional scores and re-tear rates. However, the rotator interval approach group showed a greater increase in ROM at final follow-up, especially in external rotation.

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.

Angiogenesis is a crucial step in tumor growth and progression. Scarce data is available on angiogensis in gastrointestinal tumors. We studied 16 normal colon, 44 adenomas and 29 carcinomas to evaluate angiogenesis in colorectal tumors and to assess the correlation among p53 protein, proliferative activity and other clinical prognostic parameters. Endothelial cells were immunostained with an anti-Factor VIII mAb; in each case three microscopic fields(x 200) were counted: average number of the three fields was defined as microvessel density (MVD). p53 protein expression was 45.5%(20/44) in adenomas, and 79.3%(23/29) in carcinomas (p<0.01). p53 protein expression of carcinomas was 57.1%(4/7) in diploid tumors, 100%(8/8) in aneuploid tumors (p=0.07), 100%(8/8) in well differentiated tumors, and 50%(2/4) in poorly differentiated tumors (p=0.09). MIB-1 score was 2.3+/-0.7(38) in adenomas, 3.4+/-0.5(29) in carcinomas (p<0.01). There was no significant correlation between p53 protein and MIB-1 score. MVD was 10.4+/-4.1(16) in the normal mucosa, 21.5+/-7.9(39) in the adenomas, 35.3+/-9.7(26) in carcinomas (normal versus adenomas, p<0.01; adenomas versus carcinomas, p<0.01). MVD was 25.8+/-5.4(2) in carcinomas confined to mucosa, and 36.1+/-9.6(24) in carcinomas with transmural invasion. The higher MIB-1 score was in carcinomas the more MVD increased but there was no statistical significance (r=0.38, p=0.055). MVD of carcinomas was not associated with nodal metastasis, p53 expression, and DNA ploidy. p53 protein and MIB-1 expression are useful methods for the evaluation of malignancy, and tumor angiogenesis is an early event in a colorectal tumor but MVD does not correlate with prognostic parameters except for the tumor depth.
