		                        			 Background:
		                        			A recent concern in breast reconstruction procedures is skin color mismatch of the pedicled transverse rectus abdominis myocutaneous (TRAM) flap. With the goal of objectively quantifying the skin tone of the TRAM flap donor site, contralateral breast, and flap, a comparative study was conducted. 
		                        		
		                        			Methods:
		                        			This study was conducted in July 2021, included 17 patients who received delayed breast reconstruction via TRAM flaps from January 2016 to December 2020 with at least 12 months of follow-up. Melanin levels and redness values of the flap, abdomen, and contralateral breast were measured in patients using a skin pigmentation analyzer. Furthermore, in 20 healthy women in their 40s to 60s, measurements were made of the abdomen, as well as breast. 
		                        		
		                        			Results:
		                        			The contralateral breast had lower mean melanin and redness than the abdomen. The flaps had slightly higher melanin levels than the contralateral breasts. The flaps tended to have higher redness values, but the difference was not significant. The difference between the flap and abdomen was significant for melanin, but not redness. Preoperative radiotherapy did not affect skin tone. The upper abdomen showed lower melanin and redness than the lower abdomen. 
		                        		
		                        			Conclusions
		                        			The breast had a brighter skin tone than the abdomen. The upper abdomen showed brighter skin tone than the lower abdomen, and the area used as the donor site of the TRAM flap presented the same tendency. In the process of TRAM flap engrafting, the melanin level of the tissue decreases, and the redness value tends to increase slightly compared to the contralateral breast.

		                        			  Primary cutaneous marginal zone B-cell lymphoma (PCMZL) is an uncommon type of malignant lymphoma that mainly occurs in the trunk and upper extremity, with less frequent incidence observed on the head. Herein, we report the early diagnosis and treatment of a rare case of facial PCMZL in an Asian patient. A 51-year-old man presented with masses on the forehead and nose tip, which he had incidentally discovered 2 months previously. The masses appeared as a papule on the forehead and a patch on the nose. There were no signs of infection or bleeding, and the patient reported no other symptoms. After complete surgical excision, PCMZL was diagnosed based on the permanent biopsy. The histopathological findings revealed lymphoid aggregations with multifocal granulomas. Further treatment and follow-up were conducted at the hematology and oncology department. Despite its rarity in Asian populations, cutaneous lymphoma should be included in the differential diagnosis of facial masses. Early diagnosis and treatment based on a physical examination, imaging study, and excisional biopsy are important for a favorable prognosis.

		                        			Posttraumatic pseudoaneurysm of the face is caused by blunt, penetrating, or surgical trauma. Although its incidence is low, pseudoaneurysm rupture can cause a life-threatening, massive hemorrhage. A 48-year-old man visited our emergency center due to a fall-down accident. Three-dimensional computed tomography (CT) showed a comminuted zygomaticomaxillary complex fracture of the left face. After open reduction and internal fixation, the surgical wound healed without any complications. However, the patient was readmitted 10 days after surgery due to pus-like discharge from the wound. Contrast-enhanced CT to find the abscess unexpectedly revealed a pseudoaneurysm in the left retromaxillary area. Massive oral bleeding occurred on the night of re-hospitalization and emergency surgery was done. The bleeding site was identified as a pseudo-aneurysmal rupture of the posterior superior alveolar artery in the retromaxillary area. Hemostasis was achieved by packing Vaseline gauze in the maxillary sinus using an endoscope. Delayed rupture and massive bleeding of posttraumatic retromaxillary pseudoaneurysm after a zygomaticomaxillary fracture is a low-probability, but high-impact event. Therefore, additional contrast-enhanced CT should be considered to evaluate the possibility of a posttraumatic pseudoaneurysm in cases of severe comminuted zygomaticomaxillary fracture.

		                        			 Background:
		                        			Previous studies reported that waist circumference can be a more important risk factor of chronic diseases than body mass index.Abdominal obesity is known to be associated with physical activity and lifestyle. Recent studies have found a high prevalence of abdominal obesity and low physical activity levels in Korean women. The purpose of this study was to investigate the effects of physical activity and lifestyle on abdominal obesity in Korean middle-aged women. 
		                        		
		                        			Methods:
		                        			We collected data from the 7th Korea National Health and Nutrition Examination Surveys in 2016 and 2017, and 2,274 women aged 45–65 years were evaluated. Logistic regression analysis was used to examine the association between abdominal obesity and many factors after adjusting for confounding variables with significant correlations. 
		                        		
		                        			Results:
		                        			The results showed that the mean waist circumference was 80.20±9.05 cm and the prevalence of abdominal obesity was 28.8% in the population. The low physical activity group had the largest population (48.5%). Abdominal obesity was associated with moderate and high physical activity levels (odds ratio [OR], 0.791; 95% confidence interval [CI], 0.651–0.962; P=0.019), sedentary time (≥5 h; OR, 1.495; 95% CI, 1.173–1.906;P=0.001), and weekend sleep duration (<7 h/d; OR, 1.406; 95% CI, 1.127; P=0.003). 
		                        		
		                        			Conclusion
		                        			In the Korean middle-aged women, a statistically significant correlation was found between physical activity and abdominal obesity.

		                        			Gastric lipoma is a typical benign submucosal tumor that is usually asymptomatic and is generally detected incidentally when performing gastroscopy. However, depending on its size and location, an atypical gastrointestinal lipoma can cause abdominal pain, diarrhea, constipation, intestinal obstruction, intussuception and life-threatening gastrointestinal bleeding. We report herein a case of gastric lipoma with bleeding in a 43-year-old man. The gastroscopy showed a 4x4 cm ulcero-fungating submucosal mass at the anterior wall of the gastric antrum. Laparoscopic gastric wedge resection was performed and the lesion was diagnosed as gastric lipoma.

		                        			OBJECTIVE: To evaluate the outcomes of patients undergoing percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy. MATERIALS AND METHODS: Fifty patients (mean age, 62.4 years; range, 27-86 years) who underwent percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy were included. The technical success rate, clinical success rate, complication rate, stent patency, patient survival and factors associated with stent patency were being evaluated. RESULTS: The median interval between the gastrectomy and stent placement was 23.1 months (range, 3.9-94.6 months). The 50 patients received a total of 65 stents without any major procedure-related complications. Technical success was achieved in all patients. The mean total serum bilirubin level, which had been 7.19 mg/dL +/- 6.8 before stent insertion, decreased to 4.58 mg/dL +/- 5.4 during the first week of follow-up (p < 0.001). Clinical success was achieved in 42 patients (84%). Percutaneous transhepatic biliary drainage catheters were removed from 45 patients (90%). Infectious complications were noted in two patients (4%), and stent malfunction occurred in seven patients (14%). The median stent patency was 233 +/- 99 days, and the median patient survival was 179 +/- 83 days. Total serum bilirubin level after stenting was an independent factor for stent patency (p = 0.009). CONCLUSION: Percutaneous transhepatic placement of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy is a technically feasible and clinically effective palliative procedure.

		                        			PURPOSE: To investigate the results of surgical treatment of the symptomatic accessory navicular in adolescent. MATERIALS AND METHODS: 11 patients who were 11~16 years old with symptomatic accessory navicular were identified between 2001 and 2009. Six cases were diagnosed after trauma and 8 cases were diagnosed by accident with painful bony protrusion on medial aspect of foot. In cases after at least 3 months of ineffective conservative treatment, patients were treated by resection of accessory navicular and reattachment of tibialis posterior tendon to the apex of the medial longitudinal arch using periosteum and ligamentous soft tissue without transposition of its course. And then short leg cast was applied for correction of the flat foot (if it is combined) which was molded into the longitudinal arch with the talonavicular joint released and foot inverted during about 6 weeks. RESULTS: All were type II accessory navicular without tibialis posterior tendon lesions. In most cases pain was improved, results were excellent in seven and good in four. Calcaneal pitch angle and talus-first metatarsal angle was improved about 4.64degrees and 5.79degrees in average. CONCLUSION: Symptomatic accessory navicular in adolescent might not be associated with the tibialis posterior tendon lesions. The surgical treatment composed of excision of the accessory navicular with simple replication of the tibialis posterior tendon without altering its course led to good results in most cases. The procedure has a low rate of complications. And it is easy to be performed with a good satisfaction.

		                        			PURPOSE: To investigate the results of surgical treatment of the symptomatic accessory navicular in adolescent. MATERIALS AND METHODS: 11 patients who were 11~16 years old with symptomatic accessory navicular were identified between 2001 and 2009. Six cases were diagnosed after trauma and 8 cases were diagnosed by accident with painful bony protrusion on medial aspect of foot. In cases after at least 3 months of ineffective conservative treatment, patients were treated by resection of accessory navicular and reattachment of tibialis posterior tendon to the apex of the medial longitudinal arch using periosteum and ligamentous soft tissue without transposition of its course. And then short leg cast was applied for correction of the flat foot (if it is combined) which was molded into the longitudinal arch with the talonavicular joint released and foot inverted during about 6 weeks. RESULTS: All were type II accessory navicular without tibialis posterior tendon lesions. In most cases pain was improved, results were excellent in seven and good in four. Calcaneal pitch angle and talus-first metatarsal angle was improved about 4.64degrees and 5.79degrees in average. CONCLUSION: Symptomatic accessory navicular in adolescent might not be associated with the tibialis posterior tendon lesions. The surgical treatment composed of excision of the accessory navicular with simple replication of the tibialis posterior tendon without altering its course led to good results in most cases. The procedure has a low rate of complications. And it is easy to be performed with a good satisfaction.

		                        			Patients with nonfunctioning bladders, such as found in anuric renal failure, are prone to a severe form of urinary tract infection called pyocystis. Pyocystis is the accumulation of pus in the bladder. Anuric patients are often believed to be incapable of acquiring a urinary pathogen; thus, the urinary tract may be mistakenly discounted as a possible source of sepsis and bladder rupture. Although bladder rupture is normally associated with trauma, spontaneous bladder rupture may occur, especially in patients with mental disabilities, alcohol abuse and urinary tract infection. We report a rare case of a spontaneous intraperitoneal bladder rupture, probably precipitated by pyocystis. Symptoms and signs were atypical and included pain and vomiting with fever, abdominal distension and ascites. An abdominal CT and retrograde cystography showed a large quantity of intraperitoneal fluid and tearing in the dome of the bladder. Repair of the rupture site of the bladder after laparotomy was performed. However,, the patient expired due to peritonitis and pulmonary infection.
