1.Storage of the split-thickness skin piece using proper antibiotics.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1998;25(6):997-1002
Todays, remnant split-thickness skin graft is stored for graft failure or for delayed grafting. Refrigerated skin is usually stored for 3 weeks, after which, cellular respiration ceaces. Even though the refrigerated skin can be used before 3 weeks after harvest, the success rate of the skin graft is usually lower than in case of fresh skin. One of the most reliable explanations is multiplication of microorganisms on the stored skin, that is, the more microorganisms on the refrigerated skin, the less the success rate of grafts. For this reasons, some kind of antibiotics have been used for storage of the split-thickness skin piece. But there is no report about the effect of antibiotics on stored skin. We want to know the effect of the antibiotics on stored skin. For this purpose, we did three experiments for qualititative bacteriology of refrigerated skin. Experiment 1 was qualititative identification of microorganisms colonizing split-thickness skin after 2 weeks storage in low temperature, and sensitivity tests for identified microorganisms. On the basis of experiment 1, the proper antibiotics were selected and samples of split-thickness skin were stored using this antibiotics. At 2 weeks after storage in low temperature, samples of split-thickness skin were cultured for identification of bacterial growth. This is experiment 2. Experiment 3 is histologic examination of the split-thickness skin involved in experiment 1 and 2.In the experiment 1, we found five kinds of microorganisms in 9 out of 30 split-thickness skin samples. The most common microorganism was coagulase negative Staphylococcus which was found in 4 samples. Through the antibiotics sensitivity test, teicoplanin was selected as the most proper antibiotics. In experiment 2, we could not find any microorganisms in 30 split-thickness skin samples. In experiment 3, there were no histologic differences in the split-thickness skin samples whether antibiotics were used or not. Through these results, we have confirms that split-thickness skin pieces are more safely stored using proper antibiotics.

To investigate the role of the p53 gene in the development of endometrial adenocarcinoma and to study the relation between alteration of the p53 gene and histologic grade, the author studied the alteration of thep53 gene in hyperplastic lesions and adenocarcinomas of the uterine endometrium. The study was carried out with immunohistochemical stain and PCR-SSCP. The materials included ten cases of endometrial hyperplasia (five simple and five atypical complex) and 18 cases of endometrial adenocarcinoma. Overexpression of the p53 protein were found in one of five atypical complex hyperplasias (20%) and 11 of 18 adenocarcinomas (61.1%). The intensity of p53 overexpression appeared to have increasing tendency with higher histologic grade of adenocarcinomas. Among the II cases of adenocarcinoma that overexpressed p53 protien, five cases (45.5%) were found to have mutations by PCR-SSCP. One was grade 1 (20%), two were grade 11 (25%), and two were grade III (40%). The sites of mutation were three exon 8, one exon 5, and one exon 6. In conclusion, alteration of the p53 gene may paly a role in the development of endometrial adenocarcinoma and appears to occur as a late event in carcinogenesis.HHowever, inactivation of the p53 gene in early stage of tumor development cannot be excluded.

This study was conducted to evaluate the effect of ambroxol on preventing the infantile respiratory distress syndrome (IRDS) in preterm birth at the Dept. of Obstetrics and Gynecology of Taegu Catholic Medical Center during the period from Jan. 1996 to Dec. 1996. Total of 68 cases were evaluated including 16 ambroxol group and 52 control group. The result were as follows : 1. In the comparison of preventing IRDS, there was 0 case of IRDS in ambroxol group and 7 cases of IRDS in control group (13.46 %). There was a significant difference between two groups (p<0.05). 2. The side effects of ambroxol after administration were nausea in 5 cases, headache in 3 cases, and chest discomfort in 4 cases, but these were not serious and self controlled. 3. There was no significant difference in neonatal morbidity between two groups (p > 0.05).

A clinical observation was made on 7 patients with postrenal complete anuria in the department of Urology. Medical School, Jeonbug National University during recent 3 years. The results were as follows. 1. Most common age groups were the 5th and 6th decades (57.1%), and the male to female ratio was 1.3:1. 2. Of etiology, ureteral stones were most common (3 cases), and the others were malakoplakia of both ureteral surrounding tissues (1 case), both ureteral obstruction due to renal bleeding (1 cases) post-catheterization ureteral obstruction (1 case) and ureteral compression due to metastatic cervical cancer involved lower ureter (1 case) Incidence of complete anuria were relatively high in the solitary kidney. 3. In most cases. The BUN and the creatinine levels were nearly normalized in 6th postoperative day. And 5 cases of high blood level in preoperative state showed massive diuresis after operation.

Spinal hematomas are a rare but serious complication that is typically observed in the epidural space. Spinal subdural hematomas are a dangerous clinical situation because of their potential to cause significant compression of the neural elements and can be mistaken easily for spinal epidural hematomas. This paper reports a case of a severe whole lumbar subdural hematoma after a simple epidural injection that was treated with surgical decompression with excellent clinical results.

Journal of Korean Society of Spine Surgery 2020;27(2):48-54
Objectives:
This study was conducted to identify the correlations and usefulness of lateral cervical radiographs compared with wholespine sagittal lateral radiographs for evaluating cervical sagittal alignment.Summary of Literature Review: Few reports have compared cervical lateral radiographs with whole-spine sagittal radiographs.
Materials and Methods:
We retrospectively analyzed 181 patients with both cervical standing lateral radiographs and whole-spine standing lateral radiographs. The radiographs were evaluated using the following sagittal alignment parameters: C2-7 lordosis, C2-7 sagittal vertical axis (SVA), T1 slope, spino-cranial angle (SCA), and whole-spine SVA. We evaluated the relationships between the two radiographs. The patients were divided into four groups according to age and the measured sagittal parameters were compared across groups. An analysis according to clinical symptoms was also done.
Results:
C2-7 lordosis was 16.86° and 15.76°, C2-7 SVA was 15.76° and 16.86°, T1 slope was 29.03° and 22.49°, and SCA was 74.74° and 74.5°, respectively, on the cervical and whole spine radiographs. The whole-spine SVA was -2.64 mm. Correlation analysis between the two types of radiographs showed significant relationships for each sagittal parameter. The whole-spine SVA was related with wholespine C2-7 lordosis, T1 slope, and SCA. Cervical C2-7 lordosis and the whole-spine SVA increased with age. A decrease of C2-7 lordosis on whole-spine radiographs was shown in patients with neck pain.
Conclusions
Cervical SVA and T1 slope were lower on whole-spine standing lateral radiographs than on simple cervical lateral radiographs. The cervical sagittal parameters measured on cervical radiographs were correlated with those measured on whole-spine radiographs. Cervical radiographs can be used to replace whole-spine radiographs with due consideration of these findings.
8.Clinical outcomes and optimal indications for nonoperative management of acute appendicitis in adult patients: a comprehensive literature review
Annals of Coloproctology 2025;41(2):107-118
Appendectomy as the standard treatment for acute appendicitis has been challenged by accumulating evidence supporting nonoperative management with antibiotics as a potential primary treatment. This review aimed to summarize the clinical outcomes and the optimal indications for nonoperative management of acute appendicitis in adults. Current evidence suggests that uncomplicated and complicated appendicitis have different pathophysiologies and should be treated differently. Nonoperative management for uncomplicated appendicitis was not inferior to appendectomy in terms of complications and length of stay, with less than a 30% failure rate at 1 year. The risk of perforation and postoperative complications did not increase even if nonoperative management failed. Complicated appendicitis with localized abscess or phlegmon could also be treated conservatively, with a success rate of more than 80%. An interval appendectomy following successful nonoperative management is recommended only for patients over the age of 40 years to exclude appendiceal malignancy. The presence of appendicoliths increased the risk of treatment failure and complications; thus, it may be an indication for appendectomy. Nonoperative management is a safe and feasible option for both uncomplicated and complicated appendicitis. Patients should be informed that nonoperative management may be a safe alternative to surgery, with the possibility of treatment failure.
