Uterine perforation related with dilatation and curettage (D&C) is an uncommon event. Combined complications such as hemorrhage, adjacent organ injury, and omental incarceration may require an emergent surgical treatment. These are usually evident immediately or several days after the D&C, and a delayed presentation of uterine perforation are extremely rare. Herein, we report a rare case of omental incarceration presenting as a hyperechoic endometrial mass in a postmenopausal woman, diagnosed twenty-three years after the D&C. According to this case, when we encounter a hyperechoic endometrial lesion penetrating the uterine wall in women with a history of an intrauterine procedure such as D&C, we need to consider the possibility of an incarcerated omentum.

The Non-incision "double eyelid" operation reported by Mikamoto of Japan in 1896 has the advantage of shorter operating time, less morbidity and minimal scarring thus more natural final appearance. Incidence complications of this procedure such as disappearance of the fold, asymmetry, and inclusion cyst has been reported to be higher than the incision method and there has been reports of complication rates of up to 30%. The surgeon and the patient are most worried about the complete disappearance of the surgical palpebral fold. The complications of Non-Incision ""double eyelid"" operation was evaluated in 190 patients who were available for follow up of more than 1 year. Classification of the complications which required revision surgery was classified and evaluated. There were no major complications such as blindness, retrobulbar hematoma, and blepharoptosis. Total number of complications requiring reoperation: 24(100%). The most common reoperation procedure that we experienced was asymmetry which occurred in 10(42%) patients followed by lowering of the fold line and disappearance of the fold with 6(25%) cases each. All these patients were taken back to surgery and were corrected by Non-incision method with favorable results. Conclusively, 24 complications of Non-incision double eyelid procedure experienced in 190 patients. Disappearance of the palpebral fold was seen in 6 patients who were corrected by another Non-incision technique with excellent results. The complete disappearance of the fold was experienced in very few patients and correction of this complication was satisfactory. Thus, disappearance of the fold after Non-incision double eyelid procedure should not be termed by the patient or the surgeon with full under- standing of the procedure.

Purpose: This study aimed to examine the moderating effect of organizational justice on the relationship between self-efficacy and nursing performance among clinical nurses. Methods: In January 2021, a cross-sectional survey was conducted with 224 clinical nurses recruited from a university-affiliated hospital in Suwon, South Korea. Participants completed online-based, self-report structured questionnaires. Collected data were analyzed using multiple regression and a simple model of PROCESS macro with a 95% bias-corrected bootstrap confidence interval. Results: Self-efficacy and organizational justice were found to be significant predictors of nursing performance. These two predictors explained the additional 34.8% variance of nursing performance in the hierarchical regression model, after adjusting the other covariates. In addition, organizational justice moderated the relationship between self-efficacy and nursing performance among the clinical nurses. In particular, at low self-efficacy level, participants with high organizational justice had higher nursing performance compared to those with low organizational justice. Conclusion Enhancing organizational justice can be used as an organizational strategy for improving the organizational culture in terms of distribution, procedure, and interaction. Ultimately, these efforts will contribute to the improvement of nursing performance through a synergistic effect on organizational justice beyond nurses’ individual competency and self-efficacy.

Vitamin C acts as a antioxidants and as free radical scavengers in biological systems. The objective of this study was to examine whether the administration of vitamin C could improve the skin flap survival. Sprague-Dawley rats (n = 40) were divided into 4 groups (n = 10); normal saline, vitamin C 200 mg/day, vitamin C 500 mg/day, vitamin C 1000 mg/day were injected subcutaneously to each group (n = 10). A classic caudally based random flap (2 X 7 cm) was elevated on the dorsum of rats and then sutured to its normal position. On the 3rd, 7th, 14th days postoperatively each animal was evaluated for percentage area of flap survival by paper template technique, thereafter rats were sacrificed and we obtained tissue from the distal ends of the flap. Following is our results. 1) The experimental group treated with vitamin C revealed an increased rate of random pattern skin flap survival compared with the control group (p < 0.005). 2) There was correlation of vitamin C dosage with flap survival rate (Spearman's correlation coefficient = 0.971). 3) The biopsy of the control group showed extensive atrophy and necrosis. However, New capillary proliferation and collagen deposition were noted in the vitamin C 200 mg and 500mg treated group. In the vitamin 1000 mg group, microscopic findings were very alike compared with normal rat skin texture. Finally, we concluded that the Vitamin C supplement increases survival rate of random pattern flap in rat skin flap model, and flap survival is correlated with vitamin C dosage.

PURPOSE: To evaluate the significance of T2-weighted MR imaging(T2WI) in the diagnosis of pituitarymicroadenoma. MATERIAL AND METHODS: We retrospectively evaluated the MR imaging findings of 30 cases of pituitarymicroadenoma. Diagnosis was made on the basis of surgery, serum hormonal level, and the presence of mass lesion onMR (T1WI and T2WI), and conventional as well as dynamic contrast enhanced T1WI images were obtained. In each MRsequence, signal intensity and detectability of the tumor were evaluated. We also determined whether diagnosis waspossible on both T1WI and T2WI. In eight cases, histopathologic findings (cellularity, fibrosis, and cysticchange) were correlated with T2 signal intensity of the tumor. RESULTS: T2WI, T1WI, and dynamic and conventionalenhanced T1WI detected the tumor in 21 cases (70%), 21 cases (70%), 28 cases (93.3%), and 22 cases (73.3%),respectively. On T2WI, pituitary microadenomas showed a high signal in 18 cases (60%), an iso-signal in nine(30%), and a low signal in three (10%) compared with normal pituitary gland. In 20 cases (66.7%), diagnosis ofpituitary microadenoma was possible on both T1WI and T2WI, but in one case, the tumor was detected only on T2WI.Three cases with fibrosis, as seen on histopathologic examination showed an iso or low signal on T2WI. CONCLUSION: T2WI is useful in the diagnosis of pituitary microadenoma Decreased signal intensity on T2WI may suggestfibrosis.

Craniofacial cleft is a rare congenital anomaly with a wide range of clinical manifestation and severity of deformity. In 1976, Tessier announced classification system on the basis of anatomical observation derived from clinical finding or operative dissection. Nowadays, this system is in common use because it is in accordance with terminology and observational finding and clinical manifestation is accordant with operative finding. Median facial cleft(No. 0-14 facial cleft) has a wide range of congenital malformation from a midline cleft upper lip to orbital hypertelorism, among which the bifid nose is frequently associated with hypertelorism. The manifestation of a bifid nose is variable from a simple central groove at the nasal tip to a complete clefting of the osteocartilaginous framework. In consequence, the planning of correction of the bifid nose must be individualized. We contrived correction of bifid nose using rib bone graft containing small amount of costal cartilage with maneuver of 2mm incision on nasal root skin together with fixation with 9mm miniscrew through an open approach in two No. 0-14 facial cleft patients with mild hypertelorism and bifid nose. With this method we could obtain satisfactory results in the standpoint of function as well as aesthetics. We think that this method is appropriate for correction of bifid nose of mild median facial cleft.

The treatment of fingertip amputation is difficult and controversial. Although the microsurgery has been accepted as a procedure of choice, in distal location, however, both reattachment of amputated portion as a composite graft and microvascular anastomosis are prone to failure. The fact that microscopic reconstruction of vessels is safer means of replacing amputated digits, makes considerably smaller the need to use the technique of composite graft nowadays. Nevertheless, there still remains a group of distal digital amputations which cannot be replaced by microsurgical procedure and the composite grafting is the only way of achieving a full length digit with a normal nail complex. Nowadays, it is generally accepted that replacement should be made as early as possible for the prevention of bacterial and proteolytic activity. However, if the replacement is made so quickly that bleeding doesn't stop, there is a layer of clot blocking adhesion between the two surfaces, and the union will not be achieved. We report a new strategy: the tie-over dressing ensures not only fixation, but also hemostasis, and the drainage application is used to drain retained blood, so composite graft doesn't need to be delayed until the bleeding stops. We achieved good results by using this new technique.
