The vagina is an infrequent site of primary sarcomas, which are less than 2% of all malignant vaginal neoplasm. The most common malignant mesenchymal tumor of the vagina is rhabdomyosarcoma, but leiomyosarcoma is rare type tumor of the vagina. Microscopically, spinle cells with pleomorphic nuclei and mitotic figures were frequently noted, but cross-striations were not found in the tissue. Alpha-smooth muscle actin and desmin were positive, but sarcomeric actin was negative in the tumor cells. The authors report a case of primary leiomyosarcoma of the vagina with brief literature review.

As the use computed tomographic (CT) scanning spread, the diagnosis of blowout fractures of the medial orbital wall increased. Now, the diagnosis of blowout fracture in the medial wall are not uncommon. Conventionally, the surgery of blowout fractures in medial orbital wall was performed by the various approach with external incision. The conventional method had seveal possible disadvantages, including an external scar, incomplete reduction, increased mobidity rate and general anesthesia. Recently, endoscopic reconstruction of the medial orbital wall has provided good functional and cosmetic results. We performed endoscopic transnasal reduction surgery without external incision in 12 cases of medial blowout fracture under local anesthesia. The fractured bony fragments were removed after the intranasal ethmoidectomy and the entrapped medial rectus was released. And then a sheet of silicone late or uncinate process were placed on the fracture site. For the maintain of the position of fractured wall, Merocel packing or urinary ballon catheter were used in orbital fracture site for 1-3 weeks. There were no specific complications related to this procedure. Result of the surgery in all cases were satisfactory. In this article, we discussed the surgical procedure, the benifit of the transnasal endoscopic approach, the indications for surgery, and possible comlications.

BACKGROUND: Melanin pigment plays a major role in the expression of normal human skin color as well as in the photoprotection against ultraviolet damage. Melanin produced in melanocytes is transferred via dendrites to surrounding keratinocytes, and this anatomical relationship is termed as epidermal melanin unit. The rates of pigment synthesis and transfer by melanocytes appear to be influenced by ultraviolet light, though the precise factors regulating human epidermal pigmentation remain unelucidated. It has been reported that keratinocytes in vitro release factors that could modulate melanocyte behavior. Ultraviolet irradiation was also been known to enhance the release of various kinds of cytokine from keratinocytes in vivo and in vitro. OBJECTIVE: We postulated that keratinocytes rather than melanocytes could play a primary role in UVB-induced pigmentation, and keratinocytes, when irradiated with UVB, release substances that could modulate or stimulate melanin synthesis from melanocytes. The fact that keratinocytes are located efficiently for direct sunlight irradiation at the top of melanocytes, that they release various biological factors known to simulate melanin synthesis from melanocytes and that they constitute the majority of epidermal cells supported this possibility. To investigate this possibility, we evaluated the effect of supernatant from UVB-irradiated cultured keratinocytes on the growth, melanin content, and tyrosinase activity of human melanocytes. METHODS: Human cultured keratinocytes were irradiated with UVB(30, 60, or 120mj/cm2)once, and after 24 hours, supernatant of the keratinocytes were collected and added to a growth medium of melanocytes for 5 days in concentration of 15, 25 or 35%, We observed numeric and morphologic changes as well as melanin content and tyrosinase activity in situ of cultured human melanocytes. RESULTS: 1. When cultured melanocytes were incubated with supernatant of non-irradiated keratinocytes, the number of melanocytes, amount of melanin and tyrosinase activity increased in groups added with 25% or35% concentration of supernatant. 2. The number of melanocytes incubated with 15% or 25% concentrations of supernatant from cultured keratinocytes irradiated with UVB increased in both 30 and 60mj/cm2 of UVB irradiated groups and decreased in 120mJ/cm2of UVB irradiated groups. 3. The melanin content of melanocytes incubated with 15% concentration of supernatant from UVB-irradiated cultured keratinocytes increased in 120mJ/cm2 of UVG irradiated groups. 4. The tyrosinase activity of melanocytes incubated with 15% concentration of supernatant from UVB-irradiated cultured keratinocytes increased in 120mJ/cm2 of UVB irradiated groups and the tyrosinase activity of melanocytes incubated with 25% concentration of supernatant from UVB-irradiated cultured keratinocytes increased with 35% supernatant concentration of supernatant from UVB-irradiated keratinocytes, the tyrosinase activity increased in 30mJ/cm2of UVB irradiated groups. CONCLUSION: The above results suggest that UVB-irradiated kerationcytes release soluble or photoactivated factors which could modulate the growth and melanization of melanocytes, and that keratinocytes play an important or primary role in the regulation of UVB induced pigmentation.

PURPOSE: There have been repoty on radiological features of lower respiratory track infection in infants and children caused by RSV(respiratory syncytial virus) in KOREA. The aims of this study were to summarize radiological features of lower respiratory tract infection caused by common viral agents other than RSV and to find any specific radiological features which might provide clue to the etiologic diagnosis. MATERIALS AND METHODS: We retrospectively analyzed radiological features in 51 children with symptoms of lower respiratory tract infection and identification of viral agents(except RSV). They included parainfluenza (n=22), adenovirus(n=16), influenza A(n--11), influenza B(n=2) virus infections. The mean age of the patients was 23 months. RESULTS: Major radiological findings of viral lower respiratory tract infection were bilateral parahilar peribronchial infiltration(62%), bilateral overaeration(60%), atelectasis(59%)(segmental or subsegmental atelectasis(43%), Iobar atelectasis(16%)) and patchy or confluent consolidation(20%). Pleural effusion was seen in only one case and hilar adenopathy was not observed in any of them. In the cares of adeno virus, consolidation was seen in 5 cases(31%) including 3 cases919%) of extensive confluent consolidations and overaerations were less frequent findings(44%) than in other viruses. In 24 patients with radiological follow up for more than 1 week, consolidation improved most rapidly, while was persistent atelectasis. CONCLUSION: The major radiologic features in vital lower respiratory tract infection(except RSV) were overinflation, bilateral peribronchial infiltration and atelectasis. In adenoviral infection, confluent consolidations which are usually seen in bacterial pneumonia were more common findings than in other viral lower respiratory tract infections.

Adenosquamous cell carcinoma (Ad-SCC) of the colon is rare. The pathogenesis of Ad-SCC is unclear, however, several hypotheses have been suggested. The clinical presentation and gross findings of Ad-SCC of the colon are similar to those of adenocarcinoma of the colon, but Ad-SCC has a more aggressive clinical course and a poorer prognosis. We report on two cases of Ad-SCC of the colon with obstruction; a collision-type Ad-SCC that has not only obstruction but also numerous hepatic metastases, and a composite-type Ad-SCC treated with left hemicolectomy followed by an adjuvant chemotherapy.

We experienced a case of unilateral vocal cord paralysis following tracheal extubation. The patient was a 60-year-old man undergoing subtotal gastrectomy. He had no laryngeal symptoms prior to operation and the trachea was intubated with a cuffed endotracheal tube. The surgical procedure lasted 6 hours and was uneventful. Three days later after operation, he began to complain of hoarseness and mild aspiration symptom. On endoscopic examination, left vocal cord paralysis was found. Fifteen weeks later the voice and left vocal cord function return to normal without specific management. In this case, we suggested that possible causes of unilateral vocal cord paralysis are compression of recurrent laryngeal nerve by overexpanded endotracheal cuff, laryngeal trauma during difficult intubation, stretching of the nerve as a result of traction on distant organ, decreased elasticity of trachea and surrounding tissues in the older age group and long operating time.

Malignant struma ovarii is a rare tumor of the ovary. This can be diagnosed by histologically when carcinomas of the thyroid gland are excluded. We present a case of malignant struma ovarii arising from cystic teratoma. A 42-year-old female was admitted for evaluation of lower abdominal mass. Hysterectomy and both adnexectomy were performed on the basis of a clinical impression of uterine leiomyoma and an ovarian mass. The uterus revealed intramural leiomyoma, measuring 8 cm in diameter. Ovarian mass was predominantly cystic and partly solid. Microscopically, thyroid tissue with papillary structures were found in the solid area Papillae were complex, branching and randomly oriented. These papillae were infiltrated in the adjacent fibrous capsule, Clinical evidence of a primary thyroid carcinoma was not found.
