BACKGROUND: Aurora kinase A (Aurora-A) plays an important role in the regulation of mitosis and cytokinesis. Dysregulated Aurora-A leads to mitotic faults and results in pathological conditions. No studies on Aurora-A expression in human diabetic skin tissue have been reported. In light of this, we explored the expression of Aurora-A in human diabetic skin tissue. METHODS: Aurora-A protein was evaluated by western blotting in 6 human diabetic skin tissue and 6 normal skin specimens. RESULTS: Increased expression of Aurora-A protein was detected in all diabetic skin tissue samples in both western blot analysis and immunohistochemical staining. However, in the case of the normal skin tissue, no bands of Aurora-A protein were detected in either the western blotting analysis or the immunohistochemical staining. CONCLUSIONS: Thus far, there have been no studies on the expression of Aurora-A in diabetic skin tissue. However, we believe that oxidative DNA damage related to the expression of Aurora-A protein and Aurora-A could be involved inhuman diabetic skin tissue.

Endoscopic sphincterotomy (E.S.T.) has relatively low complications and is the theraphy of choice in patients with common bile duct stones. It is also an useful technique for decompression of biliary tract obstruction. Thirty two cases of patients were selected according to opedrative risks: old age, severe jaundice and recurrent or retained bile duct stones after cholecystecomy from 1986 to 1988. The results were as follows, 1) In thirty two cases nf E.S.T., male to female ratio was 1:1.46. Most frequent age was older than 40 years. (male, 84.6%, female, 84.2%). 2) Out of thirty two cases, 20 cases (62.5% were under post clholecystectomy state, 12 eases (37.5%) were obstructive jaundice. 3) Spontaneous stone passage after E.S.T. was 81.3% (26 cases), and total stone remoral rate was 87.5% (28 cases), 4) Complications of E.S.T. were noted in three cases. In the two cases of bleeding, it was spontaneously improved and a case of acute pancreatitis was treated by medical care.

BACKGROUND: The most common complication of latissimus dorsi myocutaneous flap in breast reconstruction is seroma formation in the back. Many clinical studies have shown that fibrin sealant reduces seroma formation. We investigated any statistically significant differences in postoperative drainage and seroma formation when utilizing the fibrin sealant on the site of the latissimus dorsi myocutaneous flap harvested for immediate breast reconstruction after skin-sparing partial mastectomy. METHODS: A total of 46 patients underwent immediate breast reconstruction utilizing a latissimus dorsi myocutaneous island flap. Of those, 23 patients underwent the procedure without fibrin sealant and the other 23 were administered the fibrin sealant. All flaps were elevated with manual dissection by the same surgeon and were analyzed to evaluate the potential benefits of the fibrin sealant. The correlation analysis and Mann-Whitney U test were used for analyzing the drainage volume according to age, weight of the breast specimen, and body mass index. RESULTS: Although not statistically significant, the cumulative drainage fluid volume was higher in the control group until postoperative day 2 (530.1 mL compared to 502.3 mL), but the fibrin sealant group showed more drainage beginning on postoperative day 3. The donor site comparisons showed the fibrin sealant group had more drainage beginning on postoperative day 3 and the drain was removed 1 day earlier in the control group. CONCLUSIONS: The use of fibrin sealant resulted in no reduction of seroma formation. Because the benefits of the fibrin sealant are not clear, the use of fibrin sealant must be fully discussed with patients before its use as a part of informed consent.

Epidermal cysts are the most common cysts of the skin. Aconventional epidermal cyst rarely reaches a size of more than 5 cm in diameter. We report on two cases of giant epidermal cyst occurring in the neck. One patient had a cyst measuring 12x9x9 cm and the other patient had a non-pulsatile, dome-shaped lesion in the neck, which measured 6x5x3 cm. The lesions were totally excised. Histopathologically, both were confirmed as giant epidermal cysts.

BACKGROUND: The current health care system demands provision of quality patient care in a cost-effective manner. A clinical path defines an optimal sequencing and timing of intervention by a health care team. This path facilitates the streamlining of this process. Implementation of clinical paths may decrease hospital cost without increasing complications in acute appendicitis patients. METHODS: A prospective evaluation of a clinical pathway for acute appendicitis (during March 1999) was conducted and the results were compared with those for control patients (during Feb 1999). Pregnant patients or patients with chronic disease were excluded. The patients with acute appendicitis were classified into three groups: A-type for acute focal and suppurative appendicitis, B-type for gangrenous appendicitis, and C-type for perforative appendicitis. RESULTS: The data for 40 patients with a clinical pathway were compared to those for 30 control patients. The mean age was 25.3 11.7 years in the pathway group versus 39.3 15.8 years in the control group. The mean hospital duration were 4.5 days for the pathway with A-type appendicitis versus 5 days for the control patients (p<0.05) and the mean hospital cost was 85.73% of that for the control group (p<0.05). In B- and C-type, the hospital duration and the cost were not different. The satisfaction rates were increased in all the types of pathway patients. The complication rates for in all the pathways were no different from those for the control patients. CONCLUSION: The clinical pathway with A-type appendicitis decreased the duration of hospitalization and the cost without adversely affecting the diagnosis or the therapy. The clinical paths were useful as means to minimize cost while increasing patient satisfaction.

Korean Journal of Dermatology 2022;60(4):242-253
Background:
The Baumann skin type (BST) classification provides a new approach for clinical care of dermatologic patients.
Objective:
To investigate the correlation of skin types with genetic factors and environmental factors that have an important influence on Korean skin by comparing and analyzing the correlation between phenotype and genotype.
Methods:
From July to October 2016, 774 adults who visited the one online shopping mall were subjected to skin BST questionnaire and gene single-nucleotide polymorphism (SNP) tests. Oral epithelial cells of the subjects were collected using a Genoplan DNA analysis kit, and 14 genes were analyzed by a genetic analysis agency (Genoplan Inc., Fukuoka, Japan).
Results:
The most abundant skin type was OSNT (oily, sensitive, non-pigmented, tight) observed in 205 participants (26.5%). Of the filaggrin (FLG) SNPs, 143 participants (18.5%) had the GG (good) SNP; 391 (50.5%), GA (normal) SNP; and 240 (31.0%), AA (poor) SNP. Among those whose FLG SNP was GG (good), 121 (84.6%) were sensitive and 22 (15.4%) were resistant. Of those whose filaggrin (FLG) SNP was GA (normal), 337 (86.2%) were sensitive and 54 (13.8%) were resistant. Of those whose FLG SNP was AA (poor), 213 (88.8%) were sensitive and 27 (11.3%) were resistant. There was also a statistically significant difference in the fruit-vegetable consumption and use of a sunbathing bed between sensitive and resistant type in the groups that classified the FLG SNP as GA.
Conclusion
This is the first study to investigate the association of BST with genetic factors and environmental factors.

Background:
Nasotracheal intubation is the most commonly used method to secure the field of view when performing surgery on the oral cavity or neck. Like orotracheal intubation, nasotracheal intubation uses a laryngoscope. Hemodynamic change occurs due to the stimulation of the sympathetic nervous system. Recently, video laryngoscope with a camera attached to the end of the direct laryngoscope blade has been used to minimize this change. In this study, we investigated the optimal effect-site concentration (Ce) of remifentanil for minimizing hemodynamic responses during nasotracheal intubation with a video laryngoscope.
Methods:
Twenty-one patients, aged between 19 and 60 years old, scheduled for elective surgery were included in this study. Anesthesia was induced by slowly injecting propofol. At the same time, remifentanil infusion was initiated at 3.0 ng/ml via target-controlled infusion (TCI). When remifentanil attained the preset Ce, nasotracheal intubation was performed using a video laryngoscope. The patient's blood pressure and heart rate were checked pre-induction, right before and after intubation, and 1 min after intubation. Hemodynamic stability was defined as an increase in systolic blood pressure and heart rate by 20% before and after nasotracheal intubation. The response of each patient determined the Ce of remifentanil for the next patient at an interval of 0.3 ng/ml.
Results:
The Ce of remifentanil administered ranged from 2.4 to 3.6 ng/ml for the patients evaluated. The estimated optimal effective effect-site concentrations of remifentanil were 3.22 and 4.25 ng/ml, that were associated with a 50% and 95% probability of maintaining hemodynamic stability, respectively.
Conclusion
Nasotracheal intubation using a video laryngoscope can be successfully performed in a hemodynamically stable state by using the optimal remifentanil effect-site concentration (Ce50 , 3.22 ng/ml; Ce95 , 4.25 ng/ml).
