The authors attempted to choose what has the best reproducibility and predictability for prognosis of the prostatic adenocarcinoma among four most widely used gradings methods; the Gleason's Mostofi's, Bocking and MD Anderson hospital systems. According to these gradings systems, each of two pathologists made histologic gradings of 40 consecutive prostatic adenocarcinomas which had been diagnosed with the surgically resected specimens. Correlation between the histological grades and the clinical stages was studied and a comparison was made among each system. For the comparison, the Gleason's and MDAH systems were revised as 3 grades and adjusted to the other gradings systems. In this study, MDAH grading system yielded the highest reproducibility as represented by 90% agreement, as compared with the other systems which showed 82.5~87.5% agreement. By the Gleason's, Mostofi's and Bocking's systems, 46.2%, 23.1% and 46.2% of grade 3 tumors respectively fell under the clinical stage A. On the contrary, there were no cases of grade 3 in stage A and no cases of grade 1 in stage D, by MDAH gradings system. These results suggest that MDAH gradings system is superior to the other systems in reproducibility and for predicting the biological behavior.

To obtain the basic data of prognosis of acute carbon monoxide (CO) intoxication, one hundred and sixteen cases of CO intoxication defined by carboxyhemoglobin (COHb) and admitted via emergency room of Yeungnam University Hospital from Oct. '85 to April' 89 have been clinically analyzed and evaluated, including delayed postanoxic encephalopathy (DPE) and the following results were obtained. 1. The ratio of male to female was 1:1.5 and mental state was drowsy mostly (26.2% of 116 cases) 2. The more disturbed the mental state, the more decreased was the arterial pH and PaCO₂, which may be the result of metabolic acidosis. 3. The early laboratory findings in patients of CO intoxication were as follows: leukocytosis-65.5%, increase of hematocrit-23.3%, hyperglycemia-19.8%, increase of GPT-19.8% increase of creatinine-0.9% and glucosuria-12.1%. 4. The early findings of EKG were abnormal in 35.3%: change of rhythm-25.0%, abnormal ST segment 15.5% (change of rhythm and abnormal ST segment-5.2%) but the conduction disorder was not present. 5. The abnormal EEG above mild degree was 93.1%, of which moderate was most frequent (80.2%). 6. The incidence of DPE was 7.8% among all admitted CO patients. DPE cases had long duration of exposure time (8 hours), severe leukocytosis (20,000) and an abnormal EEG (MA).

BACKGROUND: The severity of several chronic inflammatory diseases was reported to be associated with polymorphism of the IL-1 receptor antagonist gene(IL-lrn). OBJECTIVE: This study was performed to study the polymorphism of the IL-1rn in vitiligo and in the normal Korean population. METHODS: Thirty one cases of vitiligo and seventy nine normal Koreans as control were studied for the polymorphism of IL-1 rn. RESULTS: The frequency of allele 2 of the IL- I rn in 31 patients with vitiligo was compared with that of the 79 healthy controls. The frequency of allele 2 was 1.6% in vitiligo patients and 3.8% in the normal controls. CONCLUSION: There was no significant difference in the frequency of allele 2 between the vitiligo patients and normal controls.

BACKGROUND: Primary stenting as a direct reperfusion procedure after acute myocardial infarction might reduce recurrent myocardial infarction and target vessel revascularization. However, result of long or multiple stenting in the long or tandem lesions were not known. METHOD: From Jan. 1996 to Dec. 1998, patients with acute myocardial infarction including cardiogenic shock were undergone primary stenting using long or multiple stent. The clinical end points were death, recurrent infarction, subsequent bypass surgery, or repeat angioplasty of the infarct-related vessel. The results were compared with age, sex, lesion, and risk matched standard stenting group. RESULT: Baseline characteristics were similar for the 20 patients who underwent standard length stenting and the 13 patients who underwent long or multiple stenting. Stent diameter was similar in two group (3.4+/-0.3 mm vs. 3.5+/-0.4 mm, p=0.65), but total stent length was longer in long or multiple stenting group (15.5+/-1.8 mm vs. 40.18.4 mm, p=0.01). Average numbers of stent using in multiple stenting were 1.5+/-0.7. Stenting in the infarct-related artery was successful in all patients randomized to stent treatment. At 6 months, the incidence of the primary end point was 25% (5/20) in the standard stent group and 31%(4/13) in the long or multiple stent group (p=0.5). CONCLUSION: Outcomes of long or multiple stenting including mortality, recurrent myocardial infarction and target vessel revascularization was similar to standard stenting. Long or multiple stenting after acute myocardial infarction may possible procedure in some selective cases having long or tandem lesion.

Background:
Ablative fractional CO2 laser treatment is popular for improving atrophic acne scars; however, complications after laser treatment are unavoidable. The purpose of this study was to investigate the efficacy and safety of a moisturizer containing Centella asiatica extract when applied after ablative fractional CO2 laser resurfacing.
Methods:
A split-face study was conducted between September 2020 and December 2020 on 34 patients (16 females and 18 males) who were treated with ablative fractional CO2 laser resurfacing. After laser treatment, C. asiatica extract was applied to the right side of the face and purified water was applied to the left side. We compared the right and left sides of the face at various time points after laser treatment using an automatic skin analysis device to investigate the degree of moisture and post-inflammatory hyperpigmentation.
Results:
No significant difference in the degree of moisture was found between the two sides of the face immediately after laser treatment (P=0.059), but there was a significant difference at 1 and 4 hours after post-laser treatment care (P<0.001). Regarding post-inflammatory hyperpigmentation, there was no significant difference between the two sides of the face before laser treatment (P=0.184), but a significant difference was found at 6 weeks after laser treatment (P<0.001).
Conclusions
Our results show that applying C. asiatica extract is a novel post-laser treatment modality that can provide satisfactory results without complications after ablative fractional CO2 laser resurfacing.

A 33-year-old man presented to the plastic surgery department for foreign body removal 1 month after the insertion of a continuous glucose monitoring (CGM) sensor (Dexcom G5) in the left upper arm. The patient had used the CGM system for 5 years, and the insertion was done in the usual manner. The entire sensor wire was visible on simple radiography and ultrasonography. In the operating room, and the sensor wire was identified in the intermuscular septum and removed. No foreign body reaction or inflammatory signs were found around the CGM, and the extracted wire measured 2.5 cm. Thus, it was assumed that the whole sensor wire was detached from the transmitter, not fractured. No remnant foreign body was observed on follow-up simple radiography.

Peritoneal melanosis is an extremely rare condition characterized by diffuse pigmentation in the peritoneum. Only 7 cases have been reported in the literature, 4 cases in associated ovarian teratoma, 1 case in peritoneal cyst, 1 case in ovarian teratoma and mucinous adenoma, and 1 case in enteric duplication cyst. All occurred in young females and the source of the pigmentation was inconclusive. The authors have experienced one case of primary peritoneal melanosis with mucinous cystadenoma and report our case with a brief review of literature.
