Femoral head fractures combined with hip dislocation are very rare injuries. In most cases, they result from high-energy trauma to the hip or lower extremity during traffic accidents. Various therapy options have been suggested to treat these injuries. Especially, different joint-preserving surgical options have been described for the treatment of traumatic osteochondral injury of the femoral head in young, active patients. In this report, we present a case that a traumatic osteochondral lesion to the femoral head after hip dislocation was treated with osteochondral autografts (OATS) from the non-weight-bearing area of the ipsilateral inferior femoral head through a surgical hip dislocation. After 1 year, the clinical and radiological outcome was satisfactory with no evidence of posttraumatic osteoarthritis and no pain of patients.

OBJECTIVES: The aim of this study was to identify the health and environmental risk factors of air contaminants that influence environmental and respiratory diseases in Gyeongju, Pohang and Ulsan in South Korea, with a focus on volatile organic compounds (VOCs). METHODS: Samples were collected by instantaneous negative pressure by opening the injection valve in the canister at a fixed height of 1 to 1.5 m. The sample that was condensed in -150degrees C was heated to 180degrees C in sample pre-concentration trap using a 6-port switching valve and it was injected to a gas chromatography column. The injection quantity of samples was precisely controlled using an electronic flow controller equipped in the gas chromatography-mass spectrometer. RESULTS: The quantity of the VOC emissions in the industrial area was 1.5 to 2 times higher than that in the non-industrial area. With regards to the aromatic hydrocarbons, toluene was detected at the highest level of 22.01 ppb in Ulsan, and chloroform was the halogenated hydrocarbons with the highest level of 10.19 ppb in Pohang. The emission of toluene was shown to be very important, as it accounted for more than 30% of the total aromatic hydrocarbon concentration. CONCLUSIONS: It was considered that benzene in terms of the cancer-causing grade standard, toluene in terms of the emission quantity, and chloroform and styrene in terms of their grades and emission quantities should be selected for priority measurement substances.

PURPOSE: This study was performed to evaluate the clinical outcomes of operative treatment using mini-open sinus tarsi approach for displaced intraarticular calcaneal fractures. MATERIALS AND METHODS: We studied 18 cases (16 patients) of intraarticular calcaneal fractures who were treated with sinus tarsi approach by same surgeon. The mean age of patients was 44.8 years, and mean follow-up period was 17.2 months. The measurement of Bohler angle, Gissane angle, the degree of articular surface depression, and the period to union were performed through preoperative and postoperative radiographs. The clinical evaluation was performed according to hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) and scale of the Creighton-Nebraska health foundation (CNHF). RESULTS: Bohler angle and Gissane angle had improved significantly from preoperative average 9.8degrees, 117.6degrees to average 22.4degrees, 113.4degrees immediate postoperatively, and had maintained to average 21.8degrees and 114.2degrees at the last follow-up. The degree of articular surface depression had improved significantly from preoperative average 5.2 mm to 1.2 mm at the last follow-up. All cases achieved bone union, and the period to union was average 10.5 weeks. AOFAS score was average 86.2 points at the last follow-up. There were 7 excellent, 9 good, and 2 fair results according to the CNHF scale. Therefore, 16 cases (88.8%) achieved satisfactory results. CONCLUSION: The minimally invasive sinus tarsi approach using headless compression screw seems to be an effective surgical method for displaced intraarticular calcaneal fractures, because of the possibility of accurate restoration of articular surface and the low risk of postoperative soft tissue complications.

A Spitz nevus is an uncommon benign tumor that often occurs in children. Angiomatoid Spitz nevus is a rare and distinct variant of the Spitz nevus that exhibits a spindle and/or epithelioid nevus between angioma-like, densely arranged small blood vessels. We present a case of angiomatoid Spitz nevus with high cellularity and lymphovascular tumor emboli-like features. In our case, tumor cells with high cellularity were observed throughout the lesion, and lymphovascular tumor emboli-like nests were present.

Syringocystadenocarcinoma papilliferum in situ is extremely rare. A 51-year-old female presented with a solitary yellowish patch on the scalp, accompanied by hair loss and a protruding mass. Histopathological evaluation revealed a large number of sebaceous glands and mild papillomatosis without hair follicles. The tumor contained many cystic spaces filled with amorphous material and a connection to the epidermis. The tumor cells showed papillomatous projections and were multilayered with nuclear atypia but no dermal involvement or lymphovascular invasion. On immunohistochemical analysis, the tumor cells showed immunopositivity for carcinoembryonic antigen, Ki-67, epithelial membrane antigen, and gross cystic disease fluid protein-15. Therefore, the patient was diagnosed with syringocystadenocarcinoma papilliferum in situ originating from a nevus sebaceus. The tumor was removed by wide excision, and no recurrence was observed. Our case report supports the multistep pathogenesis of syringocystadenocarcinoma papilliferum originating from a nevus sebaceus.
